Description

and the coupling members are provided with active closure surfaces which can be fitted with adjacent active closure surfaces formed on similar floorboards.

The present invention is particularly useful in connection with integrated mechanical systems for floor elements, such as those described in WO 94/26999, WO 99/66151, WO 99/66152, SE 0100100-7 and SE 0100101-5. (Aluminum AB), but they are also suitable for use in various slab systems whereby floor elements are connected to each other.

The invention is particularly applicable to sliding systems of floor elements consisting of a core and a decorative surface layer arranged on the top surface of the core, which at the same time are moisture and moisture proof.

The present invention is particularly suitable for assembling heifers whose floor members are mechanically connected to one another by means of a tongue and groove system, which is an integral part of the floor member, i.e., a factory seating system and one or more waterproof or waterproof tops. They are provided with a layer, which may also be a decorative plastic, and an intermediate core part, which is formed from a pressed plate or plastic material and preferably has a lower leveling layer on the back side of the core. The following description, while disclosing the state of the art, first addresses problems with known systems, and is not to be construed as limiting the objects and advantages of the invention in which this embodiment is the focus, and in particular laminated floors made of square rectangular floor panels. However, it should be noted that the invention may be used in conjunction with other floor elements, where the connection systems may be different, but where the floor element has a core and a final shape9S989-263SA / FT-KO (5/27/2008)

It is made with six chisels. However, the invention is also applicable to solid wood and other wood flooring having two or more layers of wood or pressed panels and a decorative wood surface layer. Thus, the invention can also be applied to floor elements which are made of fibreboard, solid wood, plywood, chipboard, fibreboard, MDF, h'DF, and the like. The invention relates in particular to problem areas related to the penetration of moisture from above the front side of a floor element. Systems for solving the moisture problem can also be used to prevent moisture penetration from the back of the floor element into the lymphatic system.

Laminate flooring generally consists of a core of 8-9 mm thick pressed fiberboard or fibreboard, and a top decorative layer 0.2 to 0.8 mm thick, which itself is laminated, and 0.1 ~ Q.8 mm thick. lower screeds made of laminated plastics, paper or similar materials. The surface layer influences the appearance of the subfloor as well as the durability of the subfloor. The core provides stability and the leveling layer keeps the base element level when relative humidity (RH) changes throughout the year. RH humidity ranges from 15% stake to 90% summer. The floor elements are usually laid in a floating system, i.e. without glue, on an existing substrate, which should be completely flat and crying. However, any unevenness occurring is compensated for by the use of a pad material, for example a board or foam, which is located between the floor elements and the subfloor. Conventional hard floor elements in this float type floor are joined to one another by tongue and tongue joints (e.g. that one floor has a tongue and the other has a tongue groove to which the former can be attached) on both the long side and the shorter side. During installation, the panels are connected horizontally by inserting a protruding tongue along a panel flange into a socket formed along the panel flange of the panel to be joined. The same procedure is followed for both longer and shorter pages.

In addition to these traditional bonded tongue and tongue and groove jointing pads, flooring elements which do not require adhesive have now been developed, instead these elements are known as adhesives. They are connected by mechanical bonding to one another, such a floor member being also disclosed, for example, in DE-A-1248. These systems work with a locking element which secures the panels horizontally and vertically. The mechanical fastening systems can be formed by 35 working of the panel core. The fastening system components may be made of a separate material which is then combined with the floor element even during manufacture.

.The greatest benefit of floating floors, at least those fitted with mechanical locking systems, is that they can be laid easily and quickly, by tapping and snaps. It's also easy to pick up and reuse in another place. A further advantage of mechanical bonding agents is that the edges and edges of the floor elements can be made of materials which do not need good adhesive properties. The most common core material for parquet is wood, in addition to fiber-based laminate floorboards of high density and generally they give good stability and are usually called HDF (high density pressed plate). Occasionally, MDF (a press plate with a density of about 10 pes) is also used as the core material.

Laminate floors, as well as many other floors, having a surface made of plastic, wood, plywood, or cork or the like, are made by applying a surface layer and a leveling layer to the core material. This application may take place by gluing the previously machined decorative layer, for example, when the pressed sheet is provided with a decorative high pressure laminate, which is formed during various operations, e.g. Impregnated paper sheets are compressed under high pressure and at high temperatures. However, the most common method used in the manufacture of laminate flooring today is direct layering or lamination, which is based on a much more modern principle and where the decorative laminate layer and the application on the fibreboard are produced in the same manufacturing operation. The impregnated sheets of paper are applied directly to the floor panel and secured without gluing using high pressure and temperature;

In addition to these two methods, there are several other methods for providing a surface layer to the core. A decorative pattern can be printed on the surface of the core, which is, for example, coated with stone 25 with an abrasive layer. The core may be provided with a layer of wood, veneer sheet, decorative paper or plastic film, and these materials may then be coated with an abrasive layer.

Generally, the above processes result in a floor element which is large and which is subsequently cut into saws, for example a few times ten floor elements, which are then processed into floor elements. In some cases, the above methods may also produce finished flooring elements, which then need not be sawn before being processed into finished flooring elements. Individual floor elements are usually made when the surface of the floor elements is made of wood or veneer.

However, the above floor elements are always individually worked along their edges to form the floor tiles. Edges are machined on precision gauges, where the floorboards are precisely aligned between one or more belts or chains, which are mounted so that they can be moved at high speed and high accuracy along the probes, which are provided with diamond tools or metal tools, and which work on the edges of the floor element. The use of a number of milling heads operating at different angles provides high-quality joint geometry at speeds greater than lpm / min, with an accuracy of ± 0.02 mm.

In the following, the visible surface of a completely finished assembled floor element will be called the "snow surface" while the other opposite surface of the floor element facing the subfloor will be called the "back surface".

The plate-like: starting material is the "core". The term "fibreboard core" refers to a core material comprising fibrous materials such as homogeneous wood, MDF HDF, pressed board, flake board, veneer sheet or fibreboard and the like. Once the core has been coated with a surface layer on the forehead and preferably also with a smoothing surface on its back surface, a semi-finished product, called a "floorboard or" floor element, is formed.

A "floor tile" is generally substantially the same size as the floor element that we intend to manufacture from the floor tile, so the floor tile can generally be converted or even converted into a floor element,

On the other hand, the floor element is typically so large that at least two floor elements can be made of it, so that the floor element can generally be divided into two or more floor tiles which are successively converted into floor elements.

Thus, when the edges of the floorboards are machined and finished floorboards are formed and the fitting system is formed, 'floorboards are obtained. "Surface layer" means any layer which is applied to the face of the core and which preferably covers the entire face. The "decorative layer" is a layer which gives the floor a substantially decorative appearance. Abrasion layer is a layer primarily intended to enhance the durability of the faceplate.

The remainder of the floor tile is the "connecting flange" at the edge of the tile between the front and the back. Usually, the connecting flange has a number of "connecting surfaces" which may be vertical, horizontal, angled, rounded, oblique, slanting, etc. These connecting surfaces may be made of various materials of the floor element, such as laminated, wood, wood, pressed or laminated board, made of plastic, metal (especially aluminum) or insulating material. The term "fly flange" refers to portions of a floor element that are close to its edge.

Αζ “Fitting or“ Flange System ^K ”refers to cooperating elements that connect the floor elements together vertically and / or horizontally.

Laminate floors, but also wood floors, are often laid in kitchens, lobbies 5 and public areas where they are constantly exposed to water because, for example, people walk on the floor with wet shoes, or clean the floor with water or the like. Nowadays laminate flooring is also used in bathrooms. Laminate and tile floors are widespread throughout the world and are common in humid climates where relative humidity can exceed 90%. 10 When water enters a material, or when moisture or condensation appears on or on a material, this is generally referred to as "moisture.

"Moisture resistant material" generally refers to a material which, to a limited extent, absorbs moisture or is a material which does not suffer from moisture.

If a laminate flooring with a fiberboard base core is exposed to a limited amount of moisture in the rooms listed above, can moisture penetrate along the joining between adjacent flooring elements for the edge of the lining system? It also penetrates into the core and the wood fibers of the core. Although the moisture absorbed is low, the water will usually evaporate after some time, but due to the constant swelling of the joint edges, the upper edge of the joint wind rises, breaking the surface layer and cracking especially if the seed quality is not good enough, and if the surface layer is thin. Elevation of the wind along the joint edges results in increased wear on the surface layer. Relatively high relative humidity has become too high for joining flanges in wood floors. They can also swell and crack.

If the effect of the moisture is strong or if it lasts for a long period of time, moisture can penetrate the entire joint system and even reach the substrate, resulting in significant degradation, such as mold,

This can occur even if the floor element is made of a moisture barrier core, since this moisture barrier core generally only prevents swelling of the connecting flanges or that moisture is spread in the core. However, the moisture-resistant core cannot prevent moisture from penetrating the lapping system and reaching the substrate. The propagation of moisture through the lining system is enhanced when the mechanical bond geometry consists of many joining surfaces on a floor member that are not in contact with the adjacent floor member. 6 ~ with wooden surfaces. Such a geometric design, for example, facilitates the sliding of the floor elements along the connecting edges of adjacent floor elements, but is not advantageous in the sense of being resistant to any moisture penetrating through the joint system,

S The common notion is that mechanical lapping systems are more sensitive to moisture than traditional glue containing lining systems because adhesives are assumed to prevent moisture from penetrating into the lining system. to allow moisture to penetrate into the priming system. One reason for this is that the adhesive is usually only part of the soldering system. Another reason is that the moisture that comes in contact with the adhesive tape dissolves the bonded bond. Moisture penetrates the ventilation system and the elements loosen at the joints.

The market share of laminate floors and adhesives, in particular at the expense of plastics and tiled floors, could increase significantly if they were more resistant to the effects of high relative humidity and water on the surface.

If the surface of the laminate floor is exposed to water, the moisture-resistant surface layer can withstand both moisture permeation through the surface and the core, and limited moisture penetration through the surface layer A and the core penetration will generally not cause damage. In the joints, moisture penetrates the upper joint edges, which are on adjacent panels, and as moisture penetrates the moisture-resistant surface layer and reaches the much less moisture-sensitive, thus much more moisture-sensitive core, the moisture spreads further along the core, towards the back of the floor element. If the core material contains wood fibers, they will swell. As a result, the thickness of the floor element increases and the surface layer increases. This vertical swelling then causes the floor to collapse. When additional moisture reaches the floor, moisture penetrates to the backside, infiltrates through the fitting system and reaches the back surface material as well as the substrate. This can cause even greater destruction.

Several procedures have been developed to solve this problem. Attempts have been made to prevent moisture from penetrating into the floor element along the connecting edge by covering the connecting surfaces with moisture-resistant insulating material such as wax or silicone. Solutions of this type are disclosed, inter alia, in WO 94/26999 (Welding Aluminum AB) and in EP 0903451 (Welding Beheer 8.V.). ERI 262509 U.S. Patent No. 4,102,125 to Dowell et al. discloses a solution in which an adhesive, preferably plastic potolefin at room temperature, or polypropylene is applied to the fitting surfaces, which when glued together at room temperature, glues them together to separate them several times at room temperature.

Attempts have also been made to stop the spread of moisture from the floor panel to the back surface of the floor member along the connecting joints by inserting a resilient insulating member between adjacent floor members. Such a solution can be found, inter alia, in WO 97/47834- (Unilin Beheer B "V").

It can be seen that many methods have been developed to increase the resistance of the Adaptive System to water and moisture in various ways,

The most popular method is that the floor tile is made of KDE panel, which is of extremely high quality, at least in terms of density and moisture resistance. A. The protection of the core from moisture can be enhanced by the addition of special binders, usually by the use of special wood fibers during the manufacture of the core. This procedure significantly reduces, but does not completely eliminate, the swelling caused by moisture. The biggest disadvantage of the procedure is its costly nature. The whole floor tile will be of the same good quality, although these special properties are useful only on certain parts of the floor element, namely the joining edges. A further disadvantage is that this procedure does not provide protection against overheating of moisture through the connection system from the front panel to the back panel of the floor panel.

However, it is also known that it is possible to treat the joining edges with special chemicals that impregnate the fiber of the joining system against moisture infiltration into the core of the floor element by means of squeezing, screening or other methods. Chemicals are applied after the joints have been machined, when they have acquired their final geometry. Generally, impregnation occurs directly during the machining of the edges of the floor elements, since the panel is then properly positioned in the machining device.

The impregnating materials may be applied to the joint system by a variety of methods, which may include spraying, rolling, dispersing and the like. The most commonly used impregnating agents are melted wax and various liquids such as oils, pollurethane-based impregnating agents, and many other compounds that prevent the penetration of moisture into the core at the joint edges, reducing the risk of swelling when the ned35 it penetrates between the upper connection edges.

.All of these procedures are extremely complex, costly and unsatisfactory. It is particularly difficult to form moisture-proof corners. If the application is applied to moving floor tiles (© (spray application, spray application may start too late and parts near the heel will not be impregnated.) If application is finished too late, the impregnating liquid may enter the air and result in unpleasant contamination. It is also difficult to impregnate the core with the connection wind directly below the surface layer without contaminating the floor surface closest to the connection edge. it is difficult to achieve deep and uniform impregnation in the layers or ranges immediately below the surface layer which is most exposed to moisture and thus to swelling. food and thus subsequent impregnation are also carried out at extremely high speeds while the surface layer of the floor tiles is facing downwards. A further disadvantage is that the impregnating agent, especially when water-based and environmentally friendly, causes swelling in the fibers, or the solidified impregnating agent layer is deposited on the ilium system and the connection geometry is changed in an uncontrollable, uncontrolled manner.

With the above methods, it is not possible to provide reliable insulation against the spread of moisture downwards from the direction of the floor panel face along the joining surfaces to the back of the floor panels. In addition, the problem of swelling of the upper edges of the joining edge © of wooden floors cannot be solved.

It is known that a plastic core material which does not swell and does not absorb moisture can be used. This provides perfect insulation against the spread of moisture in the horizontal direction from the connection between the two joined floor elements. However, plastic is disadvantageous because plastic panels are generally more expensive than fibreboard panels, and it is extremely difficult to glue or directly overlay a decorative surface layer on a plastic panel. Processing of plastic is also more cumbersome than fibreboarding and joints of floorboards. design along all four edges. An example of a floor tile made of a plastic core is nonetheless: a

EP 1 4504 A1 A1 in a disclosure document.

For example, U.S. Pat. No. 6,101,778 provides an example of a floorboard with a connecting element made of il.

The aforementioned WO 94/26999 (Válinge Aluminum AB) discloses a system for preventing the penetration of moisture into the floor panels from the joining panels and preventing the spread of moisture in the

-9floor pads from front to back. This disclosure suggests that a material made of silicone or other insulating compound, or a rubber band, or other insulating material that may be attached to the upper leg system prior to assembly may be used. The system of WO 94/26999 (Waing Aluminum AB), for example using an insulating compound or insulating device against moisture penetration applied to the joints during manufacture, also has certain disadvantages. Its main disadvantage is the same as with the flanges when spraying or lubricating impregnation. It is also extremely difficult to handle panels that contain contamination from the insulating compound. The properties of the insulating compound change over time. If the insulating compound is used when laying the floor, laying it will be extremely cumbersome and costly.

DE 20002744 U7 discloses further impregnation of floor tiles

Another possibility for providing moisture-proofing is to insert an insulating device, such as an insulating rubber strip I, into the joint during laying. This procedure is also cumbersome and expensive. If we try to fit the insulating device to the joints during manufacture, we do not know how the insulating device should be designed to work optimally, how best to install it, and how the corners should be designed to insulate work along the connecting edge of the entire floor member, taking into account both the long sides and the shorter sides. Figure 10 of the above-mentioned WO 97/47834 (Unilín Beheer SV) illustrates how an insulating device is applied to the upper joint. between the edges so that a narrow gap is created between adjacent floorboards.

The use of an insulated flexible insulating device in joints is also known for joining partition elements. This can be found, for example, in GB 2177813 (Gstrovskyj), where the described jointing system is not suitable for all floor elements which have to be laid without large visible gaps.

Further, it is known to use insulating paste or waterproof adhesive in the joints between the floorboards as disclosed in EP 05685347A1. However, in such a process, the insulation to be applied is placed at the time the panels are joined. Other drawbacks are mostly similar to those associated with glue-mounted floor elements.

It is also known (WO 99/68152, Válinge Aluminum AB) that separate materials are attached to the core edge, along the long side or the shorter side, which are attached to the core and subsequently worked to provide special functions. in the yeast system, for example in relation to system stability, and in terms of moisture resistance and resilience. However, it is not known how to apply and formulate these materials in order to solve the moisture problem described above in an optimal manner.

A special profile for floorboards and their wetting today is that of joining edges with woody floorboards, in which there are many different layers of fiber in the wood direction, since the wood swells more perpendicular to the fiber direction than in the direction of the fibers. This means that in the case of wooden flooring, where the surface layer has fibers in the longitudinal direction of the floorboard and the core has fibers in different directions, such as fibers transverse to the pad15, and is laid in an environment where moisture or relatively high humidity prevails, the surface layer swells to a greater extent transversely of the floorboard than the core. As a result, the top connecting layer, and especially the parts closest to the connecting surface, swell and expand parallel to the surface of the floorboard and expand and squeeze the floorboards while the core-formed joint system retains its original shape. As a result, destruction may occur, for example, as the decorative layer (surface layer) is compressed, the joining system is broken, or the closure functionality of the melting system is partially or completely lost.

Therefore, it can be concluded that moisture-related problems for Matched Floor Tiles are essentially the following;

> vertical and horizontal swelling of parts of the connection flange, and> penetration of moisture through the joint system,

In summary, there are a number of known methods for providing insulation against penetration of moisture and its penetration from the joining panels in the case of floorboards, however, none of which have been found to be satisfactory in terms of both quality and cost. Insulation against leakage of moisture from the front to the back 35 along the contacts is not solved, so there is no uniform insulation «φ ϊ

- 11 - where panels can be insulated during manufacture to withstand moisture penetration.

The invention is based on the discovery that a number of insulations are possible which, in particular, are formed on a damp or humidity damping system for mating floor tiles:

> "Damp-proof insulation that resists swelling of the joint edges,"> "damp-proof insulation" and "damp-proof insulation that withstands moisture and swelling through the joint system,"> "smoothing insulation" that compensates for swelling and shrinkage of the joint edges.

"Immersion insulation" means an insulation that prevents or prevents moisture from spreading from the joint edge of the floorboard to the inside of the floor, "Adhesive insulation" means an insulation that prevents or prevents moisture from penetrating through the joint, through the joint, and is an insulation that controls the movement of the material due to changes in moisture content caused by moisture in the floorboard (swelling and shrinkage), for example due to changes in relative humidity of the ambient air, and which prevents pressure stress and prevents visible gaps with one another. between the upper joint edges of adjacent floor tiles due to the movement of material caused by moisture.

As is evident from the foregoing, the known solutions to the problems caused by the dampness of the floor tiles and such solutions to the material of the floor are unsatisfactory. Some of the known solutions are unsatisfactory in terms of their intended effect, while others have disadvantages that make it difficult to manufacture or lay the floor, and other procedures or solutions are inadequate in terms of cost.

Therefore, it is an object of the present invention to eliminate or significantly reduce one or more of the floorboard flooring dependent on waterproofing in the fall. problem that still exists.

The object of the present invention is to provide a floorboard having a body and body having a fibrous core, the floorboard having at least two opposed and parallel folding edges, and the joints are mechanically connected to a floorboard similar to the floorboard. and the coupling members have active closures adapted to adjacent active λΧ closures formed on similar floor tiles, and at least one of the active closure faces being entirely or partially non-acrylic based on thermoplastic, polyethylene, elastomer, made of an elastically deformable rubber-like material,

Preferably, the groove flanges of the floorboard are provided with a moisture-resistant impregnation seal that penetrates the floorboard core from the direction of the joint, and the impregnation of the core with impregnation of the core within the joint flanges with a moisture barrier the tongue and the tongue groove, at least at a certain distance downwards, are provided with a significantly reducing agent.

The floorboard preferably has at least one layer of surface layer applied to one surface of the core, the tongue flaps and tongue grooves for connecting the floorboards vertically to each other at their edge edges. the floorboards being joined together in a vertical connection plane between adjacent floorboards provided with a moisture-proofing joint formed by a resilient insulating material formed on at least one of the two floorboards, is compressed.

The floorboard is preferably rectangular having longitudinal sides, thinner sides, a core, and a surface layer disposed on the core surface, said surface layer comprising an abrasive layer and a decorative layer, and adjacent grooves of the floorboard 20, comprising and a tongue-and-groove trigger system for connecting the floorboard to similar floorboards along the longitudinal and horizontal sides of a vertical and horizontal direction, the tongue system being at least partially machined from the core, and the floorboard further comprising a a penetration-resistant part which forms an infiltrating skeleton and which is elastically deformable, fixed to the floor tile, and p In the position of the slab when connected to a similar slab, the moisture-permeable insulating material 30 is arranged along the connecting surfaces of the connecting flanges between the adjacent slabs.

The invention is particularly advantageous in the use of floor tiles with mechanical locking systems, and in the case of floor tiles made of strip elements which are cut into a number of additional sheets before machining. However, the invention can also be used for floors where a glued pond system is provided, and for floor tiles that are manufactured directly as a separate floor element, which are then processed into floor tiles and that are not machined so as to form a large sheet of material before machining. Who.

Thus, the present invention is primarily a floorboard having a body and body having a fibrous core, further comprising at least two opposing and parallel flanges 115 and engaging means for connecting the floorboard to the floorboard in a horizontal direction, the couplings are provided with active closure surfaces which are provided adjacent to adjacent active closure edges formed on a similar floorboard, and at least one of the active closure members is formed wholly or partially of a resiliently deformable material other than the body of the floorboard.

In forming a core of a floorboard or at least two floor elements to be split into two floorboards, the core is formed of sheet material by forming part of a locking system for vertically sealing the floorboards, comprising forming a groove in the sheet material and an elastic insulating material.

Thus, in the flooring element according to the invention, the core can be provided with insulated and rigidly fixed elastic, i.e., resiliently deformable materials which act as insulation and / or leveling means against swelling and shrinkage of the floorboards. The resiliently deformable material is applied to parts that will be subsequently processed to form the finished floorboard clamping elements. The resiliently deformable material may be machined separately or simultaneously with the molding system. As a result, the resiliently deformable material can be made as a precisely fitted and precisely dimensioned insulation and forms the aforementioned seal or compensation means.

An integral part of the present invention is a process for forming a core of a floorboard or floor element to be split into at least two floorboards, comprising forming a core of sheet material to form a part of an iteration system for vertically sealing the floorboards. In the process, a groove is formed in the sheet-like material. and a flexible insulating material is inserted into the groove.

By suitable methods, such as sawing or milling, the core can be pre-treated prior to applying the surface layer (e.g., decorative surface layer) by, for example, forming one or more grooves on the surface where the edge of the joint system is subsequently machined. Subsequently, suitable insulating material is applied to the groove, by impregnation or injection, or by any other suitable method. The insulating material may be a material which insulates and / or has the property that, once solidified, is a waterproof or moisture-resistant material that is elastically deformable or deformable and is used to insulate the connection. The surface layer can then be placed on the core or on its surface above the groove provided with the insulating material. According to the invention, the insulating material can also be applied after the surface layer has been applied. The groove is subsequently formed on the floor element or floor tile in the surface layer and in the core or only in the core of the floor element. When the floor panel is sawn, the insulation material is already present in the edges.

If the insulating material has been applied in the groove or at the machined edge of the floor element, it is desirable to have the appropriate surface machined in connection with the application of the insulating material. For example, the reference surface may be an outer part of the edge of the floor element. Final machining of the joining system and machining of the seal may take place in a second manufacturing step, where the reference surface is used to adjust the floor element relative to the machining tools. By this method, it is possible to insulate the insulating material with approx. Positioned with a tolerance of 0.01 mm in relation to the connection surfaces and the surface of the floorboard. The core may be sealed at the bottom of the 0.1 to 0.5 mm thick surface layer. The gasket protects the wood fiber core and prevents moisture from penetrating through the fitting pond system. This process allows us to insulate all types of laminate flooring that can be manufactured with the insulating material. Obviously, the process can be used for thicker surfaces, such as 1 to 3 mm for plastic and linoleum surfaces. Such insulation will not be visible from the surface direction and will protect the core of the wood fibers underneath the waterproof or vapor barrier surface layer. If the insulation material is flexible, it will also prevent moisture from leaking through the joint system.

For the construction of the fitting insulation, essentially any known insulating material which can be applied in a liquid state or extruded in a semi-liquid state, for example beans or the like, can be used, which can be deformed after application, elastically deformable and additionally vapor barrier. the insulating materials have properties which enable adhesion to the core. However, such adhesion is not necessarily required, since the insulating material can be mechanically inserted into, for example, undercut grooves.

Subsequent processing of the panels takes place in such a way that the insulating material is only partially removed or modified. For example, the insulating material can be machined into a resiliently fitting insulating material that will fit snugly along the entire longitudinal side, as well as the entire shorter side and corners, and will also fit snugly into the surface layer,

The seal, and in particular the active part thereof, which effectively provides sealing to the gel against moisture, may also be formed by other external geometry, which may be performed with an extremely narrow tolerance field on the other parts of the joint system to be formed.

By providing a penetrating insulation between the decorative layer and the adjoining insulation, the result is a floor with each floor 20 having a moisture-tight connection on both its long and short sides and even at the corners. If the floor is provided with a damp-proof backing made of, for example, plastic, and which is a suitable insulation material or insulating strip applied to the floor, the floor will be sufficiently damp-proof along all joints and walls, • 25 in addition to the font imprint described above, the font can be created in several different ways, for example:

> the core can be made of a moisture-proof material,> in the case of a directly laminated floor, the upper part of the core can be impregnated directly under the decorative layer, for example as described above, an impregnating material may be applied in the grooves of the core for pressure laminated flooring, the reinforcing layer of the sheets with phenol can be impregnated with strong paper underneath the decorative layer and this can form a waterproofing insulation;> another possibility is to place a moisture resistant plastic layer between the core and the decorative surface layer throughout the panel.

Just as the seal is made, other properties, such as non-compressible materials, can be used to protect the joint edge and at the same time to provide a penetrating seal.

Waterproofing insulation may consist of one or more materials which cover the entire surface of the core and which are also resilient and have noise reduction properties. The advantage of this is that, at the same expense, moisture barrier, sound insulation and softer flooring can be achieved. Parts of the gasket may also consist of penetrating insulation. Finally, all or some of the gasket may be soaked. This means that the seal also serves as a penetrating seal with the core impregnated or not having a VAT impregnation.

As will be apparent from the foregoing, the present invention is preferably applicable to core materials made of fibrous material, such as fibreboard, but also to moisture-resistant core materials such as plastic or various combinations of plastic and fibrous material.

Examples of materials that can be used to form seals include acrylic plastic based materials, synthetic rubber elastomers, urethane rubber, slip rubber and the like, or polyurethane-based fusible adhesives.

In a preferred embodiment, the floorboards can be provided with a mechanical test system that, over a long period of time, holds the jointing flange tightly together with the insulating material or other joining edges during swelling and shrinkage of the floorboards. The system may function as a conventional glued groove joint it is more expensive and also much harder to make a tight connection than with a mechanical joint system,

In connection with laying, it is possible to use adhesives, insulating materials and other materials in the joint system described above in order to, for example, further increase the strength or the moisture resistance of the joints on certain parts of the floor or on the whole floor.

Within the scope of the invention, the longitudinal sides and the shorter sides may be formed in different ways. The reason for this is that the joining procedure used during laying can be different along the long or the short sides. For example, the longer side may be joined by an inward bending motion while the short side may be joined by a snap-type motion and may require different material properties as well as different joint geometry and insulating geometry, where

-18 one side is optimized for inward flush, while the other is optimized for flattening. Another reason is that each square meter of floor has a significantly greater length of sides than a short © side joint when the panels are oblong. The optimization of the material cost can result in different connection designs.

The impregnation of the core and the reinforcement of the flanges at certain locations prior to the application of the surface layer and the smoothing layer may also be performed on the backside, for example to reinforce the part where the lower parts of the lymphatic system are formed. a strong locking member may be formed when the tape or lower lip is machined from the core. For example, if the tape is made of a material other than the core, such as aluminum, the backside is impregnated to reinforce the critical parts where the tape is fastened or where the panel meets the sealing member.

The fabrication methods described above can also be used to form mechanical joining systems that include a flexible closure means. These resilient closures may be compressed with each other like interconnected upper flanges and may swell or expand as they shrink. In this way the horizontal swelling! problems and the appearance of a visible gap on the stem floor can be prevented. Because this is swelling! the problem is mainly on the longer sides, the corners are not considered a dangerous place in this respect. The resiliently deformable material can therefore also be mechanically applied to the groove in a solid form, for example by inserting or stamping into an undercut groove and gluing to the edge of the groove. Thus, these elastic closure devices will act as "elastic compensating insulation".

The manufacturing process described above for providing partial impregnation insulation at certain locations in the core can also be used in connection with the manufacturing of the sheet-like core. The impregnating agent can then be applied either to the mixture of wood fiber and binder that has already been converted into a core, or to the core to obtain its final shape during the manufacturing process.

Accordingly, the present invention also relates to a rectangular floorboard having long sides, shorter sides, a core, and a surface layer disposed on the surface of the core, said surface layer comprising a tile layer and a decorative layer. The floorboard is provided with a flange system adjacent to each other at the opposite flange, whereby the floor panel can be connected to similar floor panels in the grass and in the horizontal direction along the longer and shorter sides, and the joint system is at least partially machined from the core. The floor tile on this

-19 includes, in addition, a part which is provided with a damp-proof insulation which is resistant to moisture penetration from the joint edge of the floorboard into the core, said damp-proof insulation being disposed between the surface layer and a resiliently deformable joint is provided with the floorboard and which, when connected to a similar floorboard, resists moisture penetration along the connecting surfaces of the joint edges between the floorboards.

The flooring element according to the invention may also be one which is capable of forming at least two floorboards and is made of a fiber-based core and a surface layer which is attached to the surface of the core. A groove is formed on the core surface and / or on the surface layer, said groove being arranged on a part of the floor element where a mechanical joint system is formed and said groove is made of or provided with an elastically deformable material.

The flooring element used for forming the floorboard is formed by a fiber-based core and a surface layer fixed to the surface of the core, furthermore, a groove is formed at one of the upper edges of the floorboard where a mechanical joint system is formed. The groove is provided with a resiliently deformable material and / or an impregnating agent.

In the process of forming a joint between two joint edges of the floorboards, the floorboards formed with the core, at least one layer surface layer, and jointing system can be joined to each other at least vertically, whereby their upper connecting edges run along a vertical joint plane. The method comprises attaching a resilient insulating material to at least one of the floorboards, and forming an insulating material at the same time forming the joint edge of the floorboard, which is formed on at least one of the adjacent joint edges of the floorboards and pressed together when the adjacent floorboards are joined. Adhesive insulation is designed to withstand moisture penetration along the vertical joint between adjacent floorboards.

The invention will now be exemplified below. Embodiments of the invention, with reference to the accompanying drawing, are described in detail. In the drawing, the figures la to d illustrate the various steps of manufacturing floorboard, a

Fig. 2A shows a finished floorboard 1 obtained from the floorboard 2 by machining the flange, having a joint system 7, 7 'along its longitudinal sides 4a, 4b, wherein the joint system 7 is mechanical in this case.

One or more reinforcing layers 36a, 35b consisting of a paper core and impregnated with phenol is disposed beneath the decorative layer 35 and has a surface layer 31 of about 0.5 to 0.8 mm in thickness.

2d. and Figures 2e and 2e show the floor laminate 3 which is directly laminated. Abrasion 34 applied to a decorative layer 35 made of paper was applied directly to the core 30 having a decorative surface layer 31 of about 0.2. mm thickness,

3a-c. Figures 6 to 9 show a state of the art mechanical molding system and how the inventors have experimented with the effect of moisture on the masticatory systems.

3a. 1, T consists of a directly laminated surface layer 31, a wood core rosette plate core 38 (KDE) and a leveling layer 32. The vertical closure which closes the floor panels 1, Γ in the D1 direction consists of 9 tongue grooves and 10 tongue pins. The horizontal closure which closes the panels parallel to the surface layer 31 in the D2 direction comprises a coupling element 6 with a coupling element 8 which cooperates with the coupling element 12. The belt is formed by machining the core 30 of the floorboard 1 and therefore formed by the core 30. The dashed MPM arrows indicate how moisture is transmitted from the connecting edge to the core 30 as moisture enters the connection system from the top or sand surface of the floor.

3b. Fig. 6A shows an embodiment in which both vertical and water level closures are formed as a tongue groove 9 with a coupling element 12 and a tongue pin 10 having a coupling element 3. MPJ dashed arrow shows how moisture passes through parts of the joint system,

3c. As shown in Figs. 1 to 4, the floorboard 1 is provided with a surface layer 31 formed of a high-pressure laminate, a core 30 made of HDF board and a leveling layer 32 formed as a high-pressure laminate. In this embodiment as well, the vertical closure member comprises a tongue groove 9 and a tongue pin 10 formed from the core 30 of the floorboard. The coupling member 6, 3 comprises a horizontal closure member made of aluminum and mechanically connected to the core 30.

In each of these cases, the joint system is integrated with the core 30, i.e. is factory-formed and at least part of the joint system is always made by machining the core 30 of the floor element. The matching system is tilted to one another,

-22 horizontal snaps! or by snap-in at an upward angle

4a ~ 4c. Figures 1 to 8 show impregnation of prior art connection flanges 82, 83, the machined connection being impregnated with impregnating agent 24, which is applied from solution by spraying.

In order to facilitate understanding, the floorboards 1 are shown in each of the figures with the surface layers facing upwards. However, in the actual product, the floorboards 1 are generally positioned with their top side facing down during machining and subsequent impregnation.

In the state of the art impregnation technique, the depth of the impregnation on the floorboard 1 varies, and decreases directly below the surface layer, moving away from the surface layer, as is obvious from Figures 4a to 4d. with reference to the figures. Even; this operation is also carried out using protective plates 43 which protect the surface, it is also difficult to provide effective protection. The coupling element 6 and the coupling element 8 are many obstacles in the air 15 and it is extremely difficult to apply the impregnating agent 24 with sufficient accuracy and to achieve a satisfactory depth penetration under the surface layer 31 directly at the top of the joint surface edges 18.

5a ~ 5c. Figures 3 to 5 show impregnation suitable for providing a penetration seal 20 according to the present invention. The impregnating agent 24 is suitably applied to the strip-like areas 44 on the surface 33 of the core 30 before the other layers, such as the decorative layer 35 and the abrasive layer 34, are applied. For example, application may be by spraying or rolling. etc., preferably first in the longitudinal direction L of the zones where the longitudinal side 4a, 4b of the floor element 1 is later formed,

Preferably, one of the longitudinal sides 4a of the core 30 may be used as a guide surface. which is also subsequently used as a guiding surface to facilitate positioning with respect to the surface layer 31 and with respect to sawing and machining. In this way, it will be easier to ensure that the penetration insulation 20 is positioned with sufficient accuracy relative to the finished joint edge.

5b. Figure 3A shows the appropriate impregnation of those parts. which later form the 5 shorter sides of the floor element. In this impregnation, the core W is moved transversely perpendicular to the longitudinal direction L. In this case, one of the shorter sides 5 of the core 30 is used as a guiding surface for subsequent manufacture.

Fig. 5o is an enlarged view of a portion where the corners of the floorboard 1 are formed and are completely impregnated with the longitudinal side 4 as well as the shorter side 5. The dividing lines 45 indicate the line of sawing along the longitudinal side 4 and the short side 5, which is performed in order to divide the floor element 1 into floorboards 2.

8a ~ 8c. Figures 8a and 9b show in detail how the imp5 regression and penetration into the core 30 takes place, and how the impregnated area is positioned relative to the flap members 9, the tongue groove 9 and the tongue pin 10 shown in Figs. and 8b. Figures 1 to 4 are indicated by a dashed line. 8c. Fig. 2A shows the edges of two floorboards 1, 1 'made from the base element 3 after having been cut into individual floorboards 2 by sawing along the dividing line 45.

8a. Fig. 4A shows how the impregnating agent 24, when applied by spray nozzle 40, will penetrate into the core 30 from the direction of the core surface 33 and further into the central portion of the core 30 to provide a soak seal.

The penetration of the impregnating agent 24 into the core 30 may be facilitated by applying a vacuum at the bottom of the core 30 using a vacuum means 48. The vacuum means 46 may consist of, for example, a stationary vacuum tube or moving vacuum tapes. If the core 30 is stationary during the application of impregnation agent 24, for example, moving nozzles 40 are used.

Fig. 8b shows how the impregnation agent 24 is located in the core 30 of the floor element.

8c. Fig. 4a shows how the flanges 82, 83 of the floorboards 1, után look after machining. In order to simplify the drawings, only one side of the floorboard 1 is provided with a mechanical coupling part. The impregnation seal 20 is positioned exactly along the two perpendicular sides, and at the corner and above, in the embodiment shown, the connection 80,

81 edges,

The fibreboard core 30, which is, for example, HDF board fiberboard, is mixed with a binder such as melamine and then formed into a panel by pressure and heat treatment.

7a. The impregnating agent 24 is disposed on the future flanges 88, 87 il30 (dashed lines), which form flanges 82, 83 on the floorboard l and are provided with tongue grooves 9 and dowel pins 10. Most of the upper flanges 80, 81 impregnated to provide 20 penetrating insulation.

7b. Figure 3A shows that the floor element 3 is provided with a surface layer 31, a smoothing layer 32, and a core 30 having a penetration seal 20 under the surface layer 31. This

Figure 24 also shows the dividing line 45 and the directions of sawing followed by dashed lines indicating the final contours of the coupling members.

7c. Fig. 2A shows the edges of the floorboard 2, 2 'after sawing. The sawing tolerance field does not affect the position of the impregnation seal 20, which is closest to the connection flange 82. Subsequent machining requires no additional equipment to provide a soaked seal 20 at the upper ends 88, 81 of the connection system.

7d. Fig. 6A shows a machined joint with a penetration seal 20 located just below the surface layer 31. An HP horizontal plane is shown in the figure, parallel to the surface layer of the floorboard 1. The connection flanges 82, 83 of the floorboard 1, Γ may be provided with any locking system. In the illustrated embodiment, the connecting flanges 82, 83 are formed as mechanical tongue and groove joints, which can be connected to one another by inward bending and snaping. The labeled VP vertical plane (connecting plane) is perpendicular to the HP horizontal plane at the top of the edges 80, 81 near the surface layer. T is the thickness T of the floorboard 1. The maximum amount of impregnation insulation 20 is located at the edges 80, 81 of the upper joint just below the surface layer 31, for example in the region most critical to moisture. This concentration of impregnating agent 24 can be achieved directly below the abrasive layer 34 by penetrating into the core 30 from the surface of the core 30 during impregnation.

In the case of the upper connection edges 88, 81, the impregnation insulation 20 is present in the core 30 not only near the surface layer 31 between the vertical VP connector and a lower plane P2 spaced from the surface 33 of the core 38, but also horizontally. is also sufficiently extended from the VP vertical plane to a plane spaced from this Pl. This impregnated volume of the core 38 below the surface 33 forms the impregnation insulation 28.

The concentration of impregnating agent 24 is particularly high near the surface 33 of core 38. Normally, the concentration of impregnating agent 24 decreases with distance from the surface 33 of core 30, as schematically shown in Figures 4a-4d. FIGS.

The impregnation insulation 20 must be limited to a portion of the floorboard 1, primarily because of its cost, where it is intended to provide the connecting members and preferably does not cover the entire surface 33 of the core 38.

Below the surface layer 31, there is thus a penetrating seal 20 which extends over a substantial part of the fitting system 7. With regard to the transverse extent of the impregnation insulation 20, such as transverse to the VP connection plane and HP horizontal plane, it can be mentioned that Pl is 8.2 times the T floor thickness, but all difficulties are eliminated30.

- 25 may reach the value ág of the floor width, or even thicker. In many embodiments, the distance P1 may be so large that each element of the imaging system 7 is impregnated with the impregnating agent 24.

The depth of impregnation, i.e. the distance P2, is preferably 0.1 to 0.3 times the floor T thickness. However, it is often desirable that the depth of the impregnation is such that at least the upper part of the opacifier 7 is impregnated.

According to the invention, the joint system 7 is such that the penetration insulation 20 is located on the surface 33 of the core 30 between the vertical plane VP and the distance P1 measured from the VP plane, and the insulating property is substantially homogeneous within this range. The volume below the surface 33 is uniformly soaked with the impregnating agent 24. This is a significant difference from the state of the art where the application is from the VP glue and in this case the concentration of the impregnating agent 24 as shown in Figures 4a-4d. 3A, the vertical edge VP of the connecting edge decreases at a distance P1 parallel to the surface layer 31 in the direction of the panel interior and the depth of impregnation in the HP horizontal plane is nearer to the core surface 33 but at a greater distance,

Figures 8a-Se illustrate various embodiments of the invention. In this case, a groove 41 is formed on the surface 33 of the core 30, for example in the region where the inner and upper parts of the tongue pin 10 are located. The insulating material 50 is placed in the groove 41 which is moisture resistant, flexible and deformable.

8b. As shown in Fig. 4a, the core 30 having a groove 41 and an insulating material 50 is coated with a surface layer 31 and preferably with a leveling layer 32. The floor panel 3 cut along the dividing line 45 can be machined with a flap system 7. These floorboards 1 are 8o-Se. and shown in detail below.

As described above, the groove 41 could be formed on a floor element 3 or on a floor board 2 having a surface layer 31 and an equalization layer 32 fixed to the core 30. This means that the groove 41 can be formed in the surface layer 31, the smoothing layer 32 and the core 30. This groove 41 may be impregnated and / or provided with insulating material 50. This process has the advantage of using a standard subfloor element 3 and a conventional impregnating agent 24 which can be difficult to laminate or glue the surface layer 31 to the core 30.

) fí A * zo

The insulating material 50 is formed into a seal 55, preferably by being machined with tools specifically designed for working with elastically deformable plastics.

As mentioned above, there are a number of insulating materials available on the market. For example, the following materials having the following properties are mentioned:

Activated! based on plastics, and compounds having synthetic rubber elastomers, silicone gums or the like, which have properties that can be pressed into the groove 41 and adhere to the core material 30 (possibly after application of the primary layer), and have good heat resistance and moisture resistance. , are resistant to detergents and, when applied, harden or dry and solidify, taking a resilient form. The properties of the materials must be optimized in such a way that they can be deformed with sufficient elasticity and, at the same time, can be machined at reasonable costs by means of cutting tools.

Different types of polyurethane-based melt adhesives can also be used, which can be applied by heating and casting to form the joint seal. When such materials solidify, they form a solid, resiliently deformable form. These materials can later be machined, but also hot rolled or ground, which can be contacted and moved along the insulating material 50 to form the appropriate geometry.

8c. Fig. 4A shows a machined joint edge having a mechanical coupling tongue 9, a tongue pin 10, a coupling member 8, a coupling member 8, a coupling member 12 and a resiliently deformable seal 55. As is clear from this figure, the gasket 65 is a compression charge when laying the floorboard. In this embodiment, which represents an inclination inwardly, pressure and deformation occur only when the coupling member 8 is just beginning to be inserted into the coupling member 12, which here is a locking groove, and when the tongue pin 10 is already in contact with the socket groove 9. . Both mechanical and horizontal locking forces occur in the mechanical joint system, and the degree of compression of the gasket 55 increases. As a result, compression is carried out with very little force during laying, and therefore the compression constraint does not cause laying! problems.

8d. In Figs. 1 to 4, the floorboards 1, T are interconnected with each other 35, whereby the compression of the gasket 55 takes place in the same manner as described above for the cooperation between the tongue groove 9 and the nyslvesap 10,

De + but here the lateral movement along the contact planes can be easily performed and the flexible coupling members 6, 8,12 cooperate to compress the matching SS seal during snap-in.

It is extremely advantageous if the sealing gasket SS is configured such that compression can begin when the guide portion 11 of the coupling member 8 contacts the guide portion 13 of the coupling member 12. This contact may be facilitated if the guide portion 11 of the coupling member 8 is rounded or obliquely broken at the upper portions of the coupling member. The guide and compression may also be facilitated if the coupling member 12 is formed with a properly rounded guide portion 13 at the lower .

During laying, the seal 55 is pressed against the coupling surface 58 of the fitting system 7, which is then opposed to the seal 55. 8a to 8e. In the embodiment shown in Figures 1 to 4, the connecting surface 58 is grooved 45 ° relative to the horizontal HP plane of the floorboard 1. This is illustrated in FIG. . The pressure exerted by the seal 55 is evenly distributed on the vertical tongue groove 9, the tongue pin 10 and the horizontal coupling elements 6, 8, 12 of the fitting system 7. This is advantageous because we need to reduce the pressure during laying and in closed position. In the closed position, additional horizontal pressure beyond this may cause the floorboards 1, elv to separate and may result in an undesirable connection gap at the joining of the upper edges 18. Excessively high vertical pressure in the closed position may cause the connecting edge 80 to rise at the top of the tongue groove 9.

9a to 9d. Figures 6 to 9 show how the penetration seal 20 and the seal 55 can be combined in the moisture-tightening system 7. In this case, a groove 41 is formed on the upper side of the core 30 after impregnation thereof, i.e. the impregnation seal 20 is formed.

In this embodiment, both the side of the tongue groove 9 and the side of the tongue pin 10 are provided with insulating material 50a, 50b. A characteristic feature of the embodiment is that the impregnating agent 24 serves as a binder and increases the strength of the core 30. In this embodiment (Fig. 9a), impregnating agent 24 is applied to multiple areas of core 30. These areas will form the infiltration seal 20 and serve as the material reinforcement for the upper joint edges 80, 81. By impregnation, a flange reinforcement 21a, 21b is provided in the areas where the coupling member 6 is joined and in the area 21c of the core 30 adjacent the coupling member 12, where the engagement member 12 cooperates with the cap member 8.

Fig. 9b shows the location of the insulating material 50a, 50b in the groove 41. The core 30 has a surface layer 31 and an equalization layer 32 (Fig. 9c), the connecting flange and the insulating material 50a, 50b forming a seal 55a, 55b (Fig. 9d). The insulating material 50a, 50b may also be arranged in a groove which is present in both the surface layer 31 and the

It is formed in an equalizing layer 32 and each core 30.

The coupling element 8 can be secured to the core 30 in various ways (e.g., as discussed in EP 1081202 (Valing Aluminum AS) or WO 98/24895 (Valing Aluminum AB)) to provide a mechanical joint system 7 for sealing the 1,1 'floor panels together. serves in vertical and horizontal directions, includes 10 tongues10 and 9 tongues; and seals 55a, 55b; and impregnating insulation 20; and a coupling element 6 having a coupling element 8; and securing flange reinforcements 21a, 21b for the coupling member 8; and a reinforced closure 14 in the coupling 12.

The floorboards 1,1 'in this embodiment are provided with upper connection edges 80, 81 which are provided with impregnated insulation 20 in the vertical VP plane directly on the surface layer 31; and under seals 55a, 55b which are in contact with the penetrating seal 20. The penetration seal 20 and the seals 55a, 55b together with the moisture barrier surface layer 31 prevent the moisture from penetrating into the core 30 and penetrating through the lapping system 7. As a result, a moisture barrier floor is formed. As mentioned above, the vertical tongue groove 9, the tongue pin 10 and the horizontal coupling members 8, 8, 12 must be designed to carry elastically deformable seals 55a, 55b which are compressed and elastically deformed throughout the life of the floor. without, however, deforming the joint. It is particularly important for the tongue groove 9 not to be too deep in the horizontal direction and for the upper part of the tongue groove 3 or the lips 15 'to be sufficiently rigid to not rise. Further, the coupling member 8, 8 must be designed to withstand the pressure exerted by the seals 55a, 55b, but without separating the floorboards 1, és and creating a visible gap between the upper edge 81 and the connector 82. along the rim. The insulation material 50a, 50b must be selected to exert pressure throughout the lifetime of the pad and to prevent moisture from spreading through the joint system 7.

As in Sd. Also shown, the core 30 is reinforced in the flange reinforcements 21a, 21b and in the region 21c, where the coupling member 8 is fixed and where the coupling member 8 fits into the coupling member 12. This allows the use of a less expensive 30 core material, which may be of inferior quality, and is reinforced with Imp *> * · * «V * * · ♦ • 29 regns to burn greater strength in the critical ranges. good quality can be combined with low cost.

Is this moisture resistant? There are many variations of the trigger system. The seals 55a, 55b may be provided in the joint system 7 as desired, but it is preferred that the seals 55a, 55b are not visible from the surface direction, although close to the surface layer 31. It may be located on the side of the tongue groove 9 or on the side of the TG tongue, and may be located on both sides as in the embodiment shown. Of course, a plurality of seals 55 may be arranged adjacent to each other in the above connection portions. Further, the coupling surface 10 between the seal 55 and the opposite end portion of the system 7 may be configured such that its geometry is, for example, toothed, triangular, semicircular, and the like. Basically, all shapes that are commonly used when designing elastic insulating tapes or rubber bands are applicable.

The entire jointing system 7 from the surface layer 31 to the smoothing layer 32 may be provided with a penetration seal 15 20 and a flange 21a, 21b. This can increase the joint strength and resistance to moisture, give the machined belt flexibility, improve machinability and create smoother surfaces, and reduce the surfactant forces that occur when the floorboard 1 is moved relative to the other. It is also possible to impregnate the tarostanya with the plastic so that the wood fibers, together with the impregnating material, will be of such a nature that they can be formed into an insulating material.

As discussed above, FIG. The insulating material 50b and / or the penetrating insulation 20 may also be provided in grooves. The groove 41 may be formed in both the core 30 and the surface layer 31,

The insulation material 5a, 50b may also be provided at the edge of the floorboard 2 or the floorboard 1.

By varying the angles of the pressing surfaces between the resiliently deformable seals 55a, 55b, the distribution and direction of the compression force can be controlled between completely horizontal and fully vertical directions. This is advantageous if the printing surfaces are not perpendicular but inclined with respect to the HP horizontal plane so that the pressure can be divided into vertical and horizontal components so that the pressure distribution is optimal compared to the combination of materials, since the rigid upper 9 tongue grooves 15 a horizontal coupling 6, 8, 12 is formed.

10a to 10c. Figures 3 to 5 show in detail how the compression is accomplished by inward angling. The active portion 54 of the seal 55 is a convex outer surface which is compressed when the coupling member 12 contacts the

-30Switches This situation is illustrated in Fig. 10b. FIG. With the final downward bending and closing, the final compression of the mating insulation is effected by the cooperating connector 58 on the opposite side. The connecting surface S8 can be coated with, for example, wax or the like after the joint system 7 has been formed. This can facilitate displacement between the flanges in a closed position and further improve the function of the impregnation seal 20 and the sealing seal

As is evident from Fig. 1c, the fitting system 7 may have one or more expansion spaces 53a, 53b in which the seal 55 may swell when pressed against one another. The seal 55 can thus also be configured to have a certain margin and, if the joint system 7 is formed with the appropriate expansion spaces 53a, 53b, the seal 55 may be formed with smaller tolerance fields but at the same time retaining functions.

The penetration seal 20 at the upper connection edges in this embodiment is made at a greater depth from the core surface 33, which means that the entire region from the upper portion of the seal 55 to the core surface 33 is moisture resistant. In this embodiment, a large portion of the connecting flange portion between the tongue groove 9 and the surface 33 of the core forms the impregnation seal 20.

11a - 11c. Figures 11a-a show different embodiments of the invention. FIG. 4A illustrates an embodiment of the present invention wherein the seal 55 is configured to allow as little flange pitch as possible so that the connecting flanges are separated as little as possible. The contact surface of the seal 55 with its cooperating opposing interface 58 is at an angle to the panel plane, which means that most of the compression force is substantially vertical in the direction of the opening. The connecting flange in this case is the tongue and although it is rigid the risk of the flange rising is small.

11b. In the embodiment illustrated in FIG. 1A, the resiliently deformable seal 55a, 55b is disposed immediately below the surface layer 31, which layer thus covers the mating seal. The upper portion of the gasket 55a, 55b may form a penetrating seal, preventing moisture from penetrating into the core 30, while the lower portions of the gasket 55a, 55b may form the actual sealing seal. The insulation 58a, 58b may partially cover the surface layer 31 and the smoothing layer 32 near the core 30.

11c. 5a, 5Sb, which are very characteristic of the embodiment shown in Figs. These individual insulations 58a, 58b can also be used to decorate the surface layer 31 with, for example, a slant 80, so that the individual insulations 58a, 58b become visible in the joint. Such a decorative material may be used in a groove which is the final edge of the floorboard 1

It is formed in the core 30 and in the surface layer 31 and leveling layer 32 of the floorboard 2 prior to machining.

The insulation is in principle operable without the mechanical joint system 7 using adhesive between the tongue groove 9 and the tongue pin 10.

Referring to FIG. Fig. 4A shows an embodiment where a seal 20 is provided at one end of the floorboard 1 with a seal 55a at the other. The mating insulation covers the lower part of the surface layer 31. 11f. and 11g. Figures 1 to 5 show how the seal 55a and the impregnation seal 20 are inserted into the grooves 41a and 41b formed in the floor panel 1. The advantage of this method is that the insulating material can be placed with high accuracy. Furthermore, surface application can be avoided so that a considerable amount of impregnating agent can be used and the final system 7 may be formed with very high precision in a second machining step where a reference surface such as surface 10a may be used to position the floor element 1. and the application of fitting insulation can be combined in many ways. For example, both sides may be provided with impregnation insulation 20 and adhesive insulation, or only adhesive insulation or only 20 penetration insulation, etc. In this embodiment, a significant amount of impregnating material 24 is present on the upper fitting edges immediately below the wear layer 34, e.g. is the most critical for wetting. This concentration of impregnating agent 24m is the result of impregnating agent 24 leaking directly into the core 34 beneath the abrasive layer 34, where the agent leaks from groove 41b directly below the surface during impregnation. It is not necessary to protect a more calcareous surface for the final flange as this surface is protected by the remainder of the surface layer 31a and a considerable amount of impregnating agent 24 can be used. The part of the core 30 that is closest to the surface is impregnated horizontally to a depth of about 1 mm or more, and the impregnation can be practically performed at this depth over the entire edge of the floorboard. The concentration of the impregnation insulation 20 below the surface layer 31 is higher in the vertical direction at the joint surface than in the core 30. Of course, the above procedure, described in relation to the upper surface 33 of the floorboard 1, can also be applied to the lower surface of the floorboard 1.

12a. FIG. 4A illustrates an embodiment of the present invention wherein the core 30 is coated with three different surface layers having different functions. The surface of the 1,1 'floor tile comprises a transparent, hard and durable plastic wear layer 34, an intermediate decorative layer 35 made of male plastic and a reinforcing layer 38 made of resilient material which is moisture resistant and ♦ V *

It may have a 32hanging effect. The decorative film 35 made of a plastic film may be replaced by a decorative pattern applied directly to the underside of the transparent wear layer 34 or printed on the upper side of the resilient reinforcing layer 36. This embodiment can also be made without insulation and subsequently used as a heifer parquet panel having a core of fibrous material, such as HDF / MOF, a resilient surface, and a mechanical flap system 7 for vertically and horizontally extending the floor panels 1 and 4; The insulation may in this embodiment also be provided in a groove formed in the core 30 or in the surface layer of the floor panel 1.

The tongue seal 55a has an active portion 54, which is a convex protuberance and is pressed against the opposing plastic cooperating interface 56. The active portion 54 of the gasket 55 is small and leads to a reduction in friction when the short sides 5 of the floorboard 1 are laterally displaced when

1 The floor tiles are snap-connected and locked into place. Friction can be reduced by

55a, 55b, which are coated with different types of friction reducing agents.

12b. Figure 12a shows an embodiment showing the same surface layers 31 as Figure 12a. but the seals 55a, 55b are formed in the form of a resilient and deformable reinforcing layer 36 which is closest to the core 30. If the abrasive layer 34 is harder than the reinforcing layer 35, the deformation of the seal 55b will take place substantially on the lower part 57 of the mating seal closest to the core 30 and on the other hand the abrasion layer 34 will not be significantly deformed. As a result, a moisture absorption and sound absorbing floor can be created. Also in this embodiment, the impregnation insulation 20 and the jigging means formed as a sealing insulation can be designed in a number of different ways, as described above,

It will be appreciated that the above-described embodiments illustrated in Figures 6 to 12 may be combined with one another. For example, Figures 12a and 12b, or 10a. and 10b. The insulating means corresponding to the crab can be arranged in the same IS system 7, The coupling 6 can be made of aluminum, etc.

Fig. 13 illustrates a floorboard 1 having a mechanical joint system 7 along its longitudinal sides 4a, 4b, along its short side 5a, 5b and with seals 55a, 55b on one of its lower sides 5a and 4b. When joining floorboard 1 to another similar floorboard 1 '* +

-33, on both longitudinal sides 4a, 4b and on both sides 5a, 5b, there will be a seal on each side.

In addition, if penetration insulation 20 is provided at the connection flanges 20 in accordance with the above-described embodiments, the tongue and groove system 7 of the floorboards 1 is resistant to moisture penetration into the system 7 along each side 4a, 4b, at each corner 38a, 38b, 38c, 38d.

The linear machining of the shorter sides 5a, 5b and the longer sides 4a, 4b allows the corners 38a, 38b, 38c, 38d to be designed with the same narrow slot ΙΟΙ 0 as used for the longitudinal sides 4a, 4b and 5a, 5b on the sides 1 on the floorboards. The bonding insulation fits exactly in the corners 38a, 38b, 38c, 38d, and is displaced at an angle between the short sides 5a, 5b and the longitudinal sides 4a, 4b, and the misalignment between the longitudinal sides 4a, 4b , can be compensated if we ensure that

The seals 55a, 55b are deformed beyond the manufacturing tolerances when the floorboards 1 are already assembled.

14a. Fig. 4A is a cross-sectional view of a conventionally designed floor tile 1, T through the joint along the longitudinal side 4 of the wood-based floor. The surface layer 31 of the floorboards 1, T is made of wood so that the main fiber direction of the wood fibers is parallel to the longer side 4 and the core 30 is otherwise perpendicular to the longer side 4. The longitudinal side edges on the floorboard 1, ikus tongue groove, 10 rivets. 8 coupling elements, 8 coupling elements, 12 coupling elements are provided with a system. Under the influence of ambient humidity, the upper edges 80, 81 swell more transversely to the fibers (i.e., transverse to the bonding between the adjacent, flimsy floor panels 1, T) than the 30. This means that the floorboards 1,1 'are squeezed along the long sides 4 and the coupling 6 is bent backwards. This entails the risk that the upper connection edges 80, 81 or the cooperating locking surfaces 14, 18 will be compressed or destroyed. As the floorboards 1, T shrink and dry in winter (when relative humidity drops), a joining gap will appear between the upper joints 80, 87.

Figures 14b to 14e illustrate how to reduce the risk of a gap opening by applying the flexible compensating insulation 52 of the present invention to the horizontal coupling member 8, 8, 12 to withstand the effects of drizzle and shrinkage, It appears at 80, 81 edges.

Fig. 14b shows an embodiment of the floorboard 2 'suitable for supplying an insertion system 7 formed by the compensating insulation according to the invention. The contour lines of the insulating system 7 are indicated by dotted and dashed lines in Fig. 14b. The surface layer 31, core 30 and leveling layer 32 are slightly offset from each other on both sides of the tongue groove 9 and the side of the tongue pin 10 to minimize waste when machining the joining edges. A groove 41 is formed in the core 30 on the underside of the floorboard 2. A resiliently deformable material 51 is arranged and secured in the groove 41, for example by extrusion or the like, or possibly by gluing, by mechanical fastening, for example by pressing the material into the groove 41.

Compensation insulation 52 forms the active sealing surface in the coupling member 12 which operates in the horizontal direction D2. This is shown in Fig. 14c. FIG.

As the coupling edges 80, 81 swell, the elastic compensating insulation 32 is compressed by a closing surface 14 which is pressed against the closing surface 18 of the coupling element 8. As a result, the mechanical adjusting system 7 can compensate for larger displacements of the coupling at the top of the edges without damaging the fitting system 7 or creating a visible connection gap in winter when the floor dries and shrinks.

However, the problem of swelling of the upper connection flanges will be better if the surface layer 31 has a significant WT thickness and if this thickness is more than 0.1 times the floor T thickness, for example.

The ventilation system 7 according to the above embodiment is particularly suitable for use with underfloor heating in an environment where the relative humidity changes significantly throughout the year. The resilient closure member or compensating seal 52 may be disposed arbitrarily on the coupling member 8 (as shown in Figure 14d), or on the coupling member 12 (as shown in Figures 14o and 14e), and may be formed in a variety of geometries. , which are designed with different angles and radii, and which facilitate inward tilting and moving. The resilient closure or compensating seal 52 may also be combined with a penetrating seal 30 and a gasket 55 which correspond to the embodiments of the invention already described.

Figure 14d illustrates an embodiment where the resilient closure or compensator 52 serves as a moisture barrier. In this case, the compensation insulation 52, when compressed, also accommodates the movement caused by the swelling or shrinkage of the upper latching edges 80, 81. Compression and thus the insulation capacity of the compensating insulation 52 will also increase when the floorboards 1 are laid in a wet environment. In this case, impregnation insulation 20 is used, which is not explicitly shown in the figure, but which extends downwardly at least to the upper part of the connecting member in the same manner as e.g. illustrated,

14e. FIG. 4A illustrates an embodiment wherein the elastic compensation insulation 52 is compressed by a coupling member 8 made of a material other than the core 30. In this embodiment, the coupling element or strip and the coupling element 8 may be made of aluminum or other suitable metal. This construction is much more flexible than if the coupling element S was formed in one piece from the core 30 of the floorboard. The invention is also applicable in this embodiment. One advantageous feature of this embodiment is that the friction is very low during lateral displacement in the closed position.

Figures 15a-15e illustrate an embodiment of the latching system 7, wherein a seal 55 is provided in the core 30 in a groove 41 formed by a tool 70, adjacent to the upper and inner portions of the tongue pin 1 δ.

15a and 15b. Figures 6 to 7 show the critical tolerance field that is formed during machining with the tool 70, for example the position of the groove 41 in the core 30 or the position of the floor member 3 in the floorboard 1 'relative to the vertical VP plane. . 15b. Figure a

The outermost position of the tool is defined by plane TP2 outside the vertical plane VP. As is clear from these figures, the contact surfaces of the seal 55, which serve to contact the opposing, cooperating coupling surfaces 56, can be formed with high accuracy, although the TP1-TP2 manufacturing tolerance field defines the horizontal alignment of the groove 41 to the joint flange. Compared to the vertical glide environment of the VP, it is of considerable size and can exceed 0.2 times the thickness T of the floor.

15c. Fig. 55 shows a seal 55 in its compressed state with expansion spaces 53 a, 53 b on both sides of the mating insulation,

15d. FIG. 4A illustrates how to form a needle seal 55 to facilitate machining of the surface layer 31 when it is made of a laminate. The upper connecting edge sq is machined with a diamond cutter 71 which operates horizontally, i.e. perpendicular to the vertical plane VP in a position defined by arrow R, at a high wear point 72 of the diamond cutter 71 which machines the aluminum oxide-containing decorative layer 35 . The starting position of the diamond wire cutter 71 is shown by a solid line and its end position by a dashed line 71 '. If the seal 55 is located near the upper inner part of the tongue pin 10 for the position of the groove 41 and if its upper UP is at a certain SD distance from the surface layer surface 31, this SD distance may also be greater than then a seal 55 may be formed such that machining of the joint flange below the surface layer 31 adjacent thereto will be much easier. The configuration and position of the SS seal at a certain distance from the surface layer 31 allows the tongue pin 10 (Fig. 15e) and the opposite coupling surface 53 to be formed by simple machining using a tool 73.

16a-I8e. Figures 6 to 7 show headgear systems 7 having a plurality of horizontal closures. These jointing systems 7 can be moisture resistant, but are conventional mechanical jointing systems 7, which have high horizontal strength. The bases may be used in slit systems 7 which can be joined by inward bending or snaps and which include clips 6 or straps which may be optionally formed either in the core 30 or in a foreign material such as aluminum and subsequently attached to the core 30.

Several combinations of systems can be formed on the longer sides 4 and the short sides 5. The locking elements 8a, 8b, 8c and the locking grooves 12a, 12b, 12c may be formed at different angles and radii, for example, from wood, fiber-based materials, plastics and similar panel materials by means of coupling elements 8 which are machined from the core 30 or furthermore, the closures Sa, 8b, 8c may be designed such that the floorboards 1 can be connected to one another by bending or snaping.

13a. In the actuator system 7 shown in Figs. 7, there are two straps 8a, 6b, two closures 3a, 8b and two locking grooves 12a, 12b. The locking member 8a and the locking groove 12a allow locking with high mechanical strength and guiding, for example in the case of inward bending / tilting. Above all, the closure 8b provides high strength and significantly increases the horizontal closing force. The closure member 8a, 8b may be configured to operate also when the horizontal tensile force is so large that the upper connecting flanges are to be separated, for example, when a 0.05 mm or 0.1 mm joint gap is formed.

16b. Fig. 7A shows a joint system 7 with three horizontal locking elements 8a, 8b, 8c and 12a, 12b, 12c which can be formed on the basis of these principles. In this embodiment, the closures 8a and the locking grooves 12a are of good conductivity and have two closures 8b, 12b and 8c, 12c, which increase the strength of the coupling system, at least with respect to the horizontal tensile load. This system is held together by pressing the flanges together to compress the seal 55. In this embodiment, a plurality of closures may be formed on the lower and upper surfaces of the tongue pin 10 and the coupling element 8 and may be adjusted to facilitate inward bending, snap-in and guidance to increase strength.

16c. Fig. 4A shows a separate closure member 8b, a locking groove 12b and / or a locking member 12c, for example, to limit the separation of the joint system 7 where the parts of the locking groove 12a are provided with elastic compensating insulations 52.

16a. 18b and 18b. 7 to 9 are primarily suitable for snap-in, but may also be formed by small taping of the radiuses and angles of the rounding system 7. so that they can be easy-going.

16d. Fig. 7A shows a locking system 7 having two horizontal closures 8a, 12a and 8b, 12b which are suitable, for example, for inwardly tilting longitudinal sides 4.

16e. Fig. 4A is a diagram illustrating a clamping system which can be used, for example, on the short side 15, and which is laid down by means of a snap. The adapter system 7 of FIG. Fig. 7 illustrates that the closure member has a smaller and greater inclination relative to the surface layer 31 and that the band 6a is longer and more elastic, the tongue groove 9 is deeper and the closure surface 8b is more inclined relative to the surface layer 31,

The locking grooves 12b and 12c can be formed in a more advanced form with tools that do not need to rotate. 16f. Fig. 18b shows an undercut locking groove 12o in Fig. 18b. figure? iiiesztőrendszerben. The panel can be moved in accordance with state of the art metalworking along a stationary groove-forming tool 74 provided in this embodiment with teeth 75 which work in layers on the surface layer 31. When the floorboard 1 moves in the direction of arrow B, the floorboard 1 passes along the groove-forming tool 74 which is inserted into the tongue groove 9 and whose teeth form the final shape of the undercut coupling 12 with its locking surface.

1? A - 1? D. Figures 3 to 5 show an enlargement of the corner 38a of the floorboard 1, which has already been shown in Figure 13, showing three connections 1, Γ, 1 ”. For example, corners 38a, 38b, 38c, 38d are critical parts of a moisture resistant floor. In order to resist moisture penetration into the connection system through the core 30, it is preferable that the seal 55a, 55b does not break at least one corner 38a, as shown in FIG. is shown. Furthermore, the Membrane Γ in the corner 38d of the ap floorboard must be designed in such a way that the 54 active parts do not

17c and 17d illustrate the interface system 7 shown in FIG. 17b. Fig. 4A is a cross-sectional view taken along the line C1-C2, i.e. the corner 38a and the shorter side 5 of the floorboard 1 'is a side view, where the floorboard 1 is shown in cross section along the C1-C2 lines. In this embodiment, the active portion 54 of the mating insulation in the floorboard ól is intact at the outer end of the upper lip of the tongue groove 9b. This is due to the fact that the active part 54 is located in a region SA which is between the surface layer 31 and the upper part of the tongue groove 3b, which in this case is undercut. The active portion 54 of the mating halo will thus be in contact with the cooperating interface 58 of the third floor panel 1 in this plane SA.

In this embodiment, the continuous and unbroken seal 55a is located in the SA region of the corner 38a. Therefore, there are no gaps or cavities where moisture could penetrate from the surface direction and spread through the lining system 7. Therefore, in this embodiment, it is characteristic that the seals 55a, 55b in the two corners 38b, 38d of the floorboard 1 are in continuous contact with the opposed cooperating connection surface. The active portion 54 of the seal 55 is thus continuous along the entire longitudinal side 4 and over the entire length of one of the short sides 5 and at the corners between the longitudinal sides 4 and 5.

The system described above is one of two interconnecting 4a,

In this system, penetration insulation 20 is provided at the joints 80, 81 of the floorboard 1, which resists moisture penetrating into the core 30 of the floorboard from the direction of the connection flanges 82, 83 and is substantially impregnated with the core 30. formed by impregnating agent 24 within the connection flanges 82, 83 which substantially reduces the swelling caused by moisture by impregnation from the upper surface 33 of the core 30, which is formed at least a certain distance downwardly towards the tongue pin 9 of the tongue 9.

In the system, the concentration of impregnating agent 24 on the flanges 88 _and 87 is greater than a certain distance from the core surface 33.

In the case of the floorboard 1, the core 30 may be impregnated over a distance of less than half the distance between said opposite joint edges,

In the case of the floorboard 1, the core 38 can be impregnated within said connection edges, within which portions of the connecting elements 6 to 10, 12, 14, 18 are at least partially formed on the floorboard.

The floor panel 1 may be rectangular and opposed at the edges of the joint. In the case of the floor panel 1, the joining edge portions on the top side of the floor panel 1 may be impregnated with a moisture barrier agent and / or an agent that resists or significantly reduces moisture swelling.

In the case of the floorboard 1, the joining edges on the lower part of the floorboard 1 can be imp20 adjusted with a resilient enhancer.

The floor panel 1 may comprise a resiliently deformable active portion 54 which is attached to the core in a position such that during the processing of the floor panel 1, the panel 1 is formed by the coupling 8-10, 12, 14, 18 and / or the core 38 of the floor panel 1. of parts of the upper parts of the connecting parts.

According to the invention, the connection «» «

The leading edge portions are formed by an insulation penetrating the floor panels 1 which resists moisture penetration into the core of the floor panel 1 in the direction of the connecting plane. This impregnation seal is formed by impregnating the core with a moisture barrier within said joint edge and / or one that resists or substantially reduces the swelling caused by moisture penetrating from the top surface of the core and at least at a certain distance is formed in the direction of the connecting parts.

This impregnation can extend to a depth of at least 0.1 times the thickness of the floorboard 1 when viewed from the top of the core.

Impregnation of the bottom sheet of the core may be accomplished by the action of a property enhancer, particularly an agent that improves the mechanical properties of the core.

For some ilst systems, it is possible to improve the strength and elastic properties of the core 30 to better suit its function and to this end select the starting material for the mechanical coupling.

In this embodiment, the required properties of the core are achieved within the portions of the floorboard 1 that are most exposed to various effects, such as the edge portions. This represents a major economic advantage since the impregnation of the core 30 is limited to a precise range which needs to be improved in order to provide a floor with the desired properties, i.e. resistance to moisture penetration. Therefore, the impregnation of the core 30 is preferably less than half the distance between the opposing edges of the core 30. More preferably, the impregnation is limited to the portions of the edges within which at least a portion of the connecting means is formed.

In this case, it is particularly advantageous, as mentioned above, to treat the lower portion 30 of the core with an egal enhancer, in particular an elasticity enhancer, so that this lower lip or sealing strip achieves optimal properties with respect to its function. However, within the scope of the present invention, such a sealing tape may be made of various materials, such as aluminum, and in this case, the core portions that form the bond to the separate sealing tape may advantageously be impregnated with such a property enhancing agent. the ability of the core to hold the sealing tape attached thereto.

In this embodiment, the insulating material is in the core and thus not in the entire joint edge, which is impregnated at the point where the joint system is subsequently formed.

The result of the impregnation can be achieved before the floorboards 1 are finally machined, and as a result, high capacity and significant cost savings can be achieved by reducing the amount of cell.

Absorbent insulation is very suitable for all fiber-based core materials, such as homogeneous wood, fibreboard and multi-ply plywood, as well as for laminated timber, fibreboard such as HDF and MDF, plate, flake plate and the like. The process can also be applied to other core materials, such as those that do not contain wood fibers and would not swell when exposed to moisture, but where it is intended first of all to impregnate certain parts thereof to obtain reinforcement or reinforcement of the edges. .
