Description

The present invention relates to a plate element, in particular for the construction of furniture, having a polygonal upper surface, a polygonal lower surface and the upper surface and the lower surface connecting side surfaces, wherein the upper surface and the lower surface are flat and parallel to each other.

Furthermore, the present invention relates to a connecting element, in particular for the construction of furniture, for connecting at least two plate elements with at least two receiving elements for receiving a respective plate element.

Moreover, the present invention also relates to a connection system comprising a plurality of such plate elements and a plurality of such connection elements.

With a connection system in the context of the present invention, for example, furniture such as chairs, armchairs, sofas, beds, tables, shelves and cabinets, children's toys such as doll houses, climbing frames, inner partitions and shields, exhibition stands, tents and shelters and containers for storage and Build transport such as suitcases, boxes and chests. All of these examples include plate-like elements, which are usually connected to each other either by fasteners such as screws, hinges or fittings or by bonding with the aid of a corresponding adhesive make a firm connection with each other. However, this has the consequence that such connections between the individual plate elements only with difficulty and in a complicated manner or not at all be separated from each other. While adhesive bonds between individual plate elements are insoluble, plate elements held together by screw connections, hinges or fittings can indeed be separated again, however, connecting elements in the form of screw connections, hinges or metallic fittings always go hand in hand with a fixed attachment of hinges or metallic fittings on the individual plate elements or with holes through the individual plate elements for fixing screws. In addition, the loosening of screw, hinges or fittings is time-consuming, especially in a large number of to be connected or to be separated from each other plate elements.

The publication EP 1 203 549 A1 discloses a kit for making furniture, a variable furniture composed of such a kit, and a method of manufacturing a variable piece of furniture from said kit. In this case, a Velcro strip fixedly attached to a first element and a Velcro strip fixedly attached to a second element are used, so that the two velcro strips connect the first element to the second element in the manner of a hook-and-loop fastener by pressing the two velcro strips together. While this construction allows easy and quick assembly and disassembly, the hook-and-loop tapes disclosed therein have neither sufficient flexibility to form a hinge nor provide a sufficiently strong connection and thus can not prevent unwanted loosening of the two hook-and-loop tapes. Also has a construction according to the document EP 1 203 549 A1 the disadvantage that the resulting connection is not symmetrical and that not several plate elements along a center line can abut each other.

Rigid angular connections between individual plate elements have in contrast to the Velcro strip according to the document EP 1 203 549 A1 again the disadvantage that at least two separate screws for mounting each individual angle connection are needed, which makes the assembly and disassembly consuming and time-consuming. Both of the above-mentioned connection systems also have in common that they provide neither hinges nor the ability to attach other elements such as table legs and chair legs, wheels, handles or the like to the angle elements.

An object of the present invention is to provide a connection system which makes it possible to connect the individual elements with the aid of the connecting elements quickly, easily, flexibly and safely.

A further object of the present invention is that the connection system according to the invention can be easily disassembled by hand, without the need for a great deal of force or other tools.

An object of the present invention is also to provide a connection system, which has the widest possible scope such that other elements such as columns, table legs or chair legs, wheels, handles and the like can be integrated in a simple and secure manner.

At least one of these tasks is solved by:

• A panel having a polygonal top surface, a polygonal bottom surface, and side surfaces connecting top surface and bottom surface, wherein the top surface and the bottom surface are planar and parallel to each other, wherein a plurality of edges of the plate member are at least partially under one Angle of 45 ° or less to imaginary extensions of the top surface and the bottom surface is chamfered, wherein on the top surface and the bottom surface for each corner of the plate member at least one surface portion is provided which is designed such that it between this surface portion and a gravitational or positive locking force acting on a surface portion complementary to this surface portion and engageable with this surface portion surface portion of a connecting element in a direction parallel to the upper surface and the lower surface of the plate member,
• 2. a connecting element for connecting at least two plate elements with at least two receiving elements for receiving a respective plate element, wherein the at least two receiving elements along a connecting line are interconnected and each of the receiving elements has two along the connecting elements interconnected contact elements each having an inner surface, wherein the contact elements are configured such that between the inner surfaces of the two contact elements, a plate member is receivable, wherein the inner surface of the contact elements each having a surface portion configured such that this surface portion between this surface portion and a complementary to this surface portion and engageable with this surface portion surface portion of the plate member in the direction parallel to the upper surface and the lower surface of the plate member acting shear forces frictionally or positively receives, and
• 3. a connection system with at least two plate elements, as described above, and connecting elements, as described above, wherein in at least one connecting element in each case at least two plate elements are received such that the inner surfaces of the two contact elements of a receiving element of the connecting element respectively at least partially comprise one of the chamfered side surfaces and a portion of the upper surface and the lower surface, wherein each arranged on the inner surfaces of the contact elements surface portion with a surface portion complementary surface portion of the plate member is engaged such that a frictional or positive connection between the in engagement surface portions for receiving acting shear forces in the direction parallel to the upper and the lower surface of the plate member.

The plate elements according to the invention have on their upper surface and on their lower surface for each of their corners in each case a surface portion which is designed such that it can be brought into engagement with a surface portion complementary to this and arranged on a connecting element surface portion, so that in a Direction parallel to the upper and the lower surface of the plate member acting shear forces are positively or positively recorded.

The acting shear forces in the direction parallel to the upper and lower surfaces of the plate member denote forces acting on the upper and lower surfaces of the plate member acting parallel to these surfaces. These shearing forces arise at the centerline of the plate member and act between the surface portion of the plate member and the complementary surface portion of a connecting member when in engagement. However, due to the inventive configuration of the engaged surface portions, in which the acting shear forces are received in the direction parallel to the upper and lower surface of the plate member, slippage of the two surface portions relative to each other is prevented and a stable, secure connection between the engaged surface portions allows.

In addition, the arrangement of the surface sections leads to a uniform distribution of the resulting holding forces on the individual plate elements and the connecting elements. As a result, heavy plate elements can be safely and easily connected to each other.

In one embodiment of the present invention, a plurality of edges of the plate member are chamfered at least in sections at an angle of exactly 45 ° to imaginary extensions of the top surface and the bottom surface. Chamfering the edges of the plate element at an angle of 45 ° makes it possible to arrange four plate elements along a common connecting line with the aid of connecting elements according to the invention such that the four plate elements are each aligned at an angle of 90 ° to each other. Also, in particular two plate elements can be aligned by connecting elements according to the invention at an angle of 90 ° to each other. This is for example in the assembly of furniture such as Cabinets from the plate elements according to the invention and connecting elements of advantage, since such pieces of furniture usually require a rectangular construction.

In a further embodiment of the present invention, a plurality of edges of the plate member are chamfered at least in sections at an angle less than 45 ° to imaginary extensions of the top surface and the bottom surface. Such a configuration of the chamfered edges of the plate elements makes it possible to connect more than four plate elements along a connecting line with the aid of connecting elements according to the invention. This is particularly advantageous if structures are to be built from the plate elements, which do not require or should have any rectangular arrangement of plate elements to each other. Examples include climbing frames, in which plate elements are often aligned at an angle less than 90 ° to each other.

In one embodiment of the present invention, the plate member is configured such that the upper surface and the lower surface of the plate member each have a mounting hole for each corner, wherein the mounting holes on the upper surface are mirror-symmetrical to the mounting holes on the lower surface and wherein Center of each mounting hole of the two edges forming the hole associated with this hole of the plate member has a measured in a direction perpendicular to the respective edge equal spacing, and each of the mounting holes is surrounded by a surface portion of the upper surface or the lower surface.

In a preferred embodiment, the distance of the mounting hole to the edges of the plate member is less than half the length of each shortest edge of the plate member. The mounting holes can be both continuous and non-continuous, i. in the form of blind holes, be configured.

In another embodiment, the mounting holes are biconical mounting holes, with the diameter of the mounting holes each decreasing from the top and bottom surfaces of the plate member to the center between the top and bottom surfaces of the plate member. The mounting holes serve to provide, for example, additional brackets in these mounting holes and thus enhance the effect of a stable and secure connection between panel members and connectors. This is particularly advantageous if the plate elements are such heavy plate elements that the absorption of the acting shear forces by the engaged surface portions of at least one plate element and at least one connecting element is no longer completely possible.

In a further embodiment of the present invention, the surface portion disposed on the upper surface and the lower surface of the plate member comprises an element of a hook-and-loop fastener. For the purposes of the present invention, a hook-and-loop fastener describes a textile fastener which can be released almost as often as desired, which is typically in the form of two woven chemical fiber strips, for example consisting of polyamide or polyester fibers. The first chemical strip has flexible barbs while the second buff has loops. Due to the juxtaposition of the first and second man-made strands, the chords of the first man-made stripe hook into the loops of the second man-made stripe to form a load-bearing reversible quick release.

A characteristic feature of a hook and loop fastener is its tensile strength and tensile shear strength. When the surface portions disposed on the upper surface and the lower surface of the plate member, which is an element of a hook-and-loop fastener, i. either flexible barbs or loops comprise, are brought into engagement with a surface portions of a connecting element complementary to these surface portions, this resulting Velcro fastener provides for a positive reception of the shear forces acting in the direction parallel to the upper and the lower surface of the plate member. The resulting hook and loop fastener thus enables a stable connection between plate elements and connecting elements and prevents slippage between plate elements and connecting elements by the engagement of barbs in loops.

In an alternative embodiment, the surface portion disposed on the upper surface and the lower surface of the plate member comprises a tooth structure. Such a surface portion with a tooth structure is engageable with a complementary, also a tooth structure comprising surface portion of the connecting element, so that the engaging surface portions due to the interdigitated teeth of the two tooth structures acting in the direction parallel to the upper and lower surfaces of the plate member Record shear forces with a positive fit. Such a configuration of the opposing surface sections prevents slippage between the plate element and connecting element.

Such a tooth structure usually consists of a harder material than an element of a hook-and-loop fastener, so that a connection formed by intermeshing teeth of two tooth structures is less elastic than a connection by Velcro. Depending on the field of application, it should therefore be selected whether a hook-and-loop fastener or a connection resulting from intermeshing teeth of two tooth structures is the appropriate variant.

In a further alternative embodiment, the surface portion disposed on the upper surface and the lower surface of the plate member is permanently magnetic. This has the consequence that the surface portion with a complementary surface portion of a connecting element, which is also permanently magnetic or at least ferromagnetic, is engageable by a magnetic force of attraction. Incidentally, in one embodiment, the magnetic attraction force is stronger than the shear forces acting in the direction parallel to the upper surface and the lower surface of the plate member, so that the shear forces are compensated by the magnetic attraction force and a stable frictional connection is made between the plate member and the connection member.

In one embodiment, the permanent magnetic surface portion is a magnetic adhesive tape. For example, some self-adhesive self-adhesive magnetic tapes such as SETON (0.77 N / cm ² ), Schallkammer magnetic systems (0.8 N / cm ² ) and HajoFix (0.72 N / cm ² ) have an adhesive force of between 0.7 N / cm ² and 0.85 N / cm ² . Even stronger magnetic tapes with an adhesive force beyond 1 N / cm ² , for example, from the company Magnosphere (1.8 N / cm ² ), are commercially available. Even after repeated opening and closing magnetic tapes do not lose their adhesive power.

In one embodiment of the present invention, the plate member is made of a frame, wherein the frame is filled with a filling material and frame and filler are surrounded by a sheath such that the sheath arranged on the upper surface and the lower surface of the plate member surface portions and possibly leaving any fixing holes free. In one embodiment, the frame is made of light metal, in an alternative embodiment the frame is made of a plastic and in another embodiment the frame is made of wood. In one embodiment, the sheath is a sheath of a material selected from a group consisting of a textile material, a material impregnated with a polymer, for example, polyvinyl acetate, and rubber, or a combination thereof.

In a further embodiment, the filling material of the plate element comprises dried mushroom components. Such fillers grow in the frame with the addition of water and flour and are dried after the mushroom completely fills the frame. In one embodiment, the dried mushroom components are mycelia, i. H. around filamentous cells of a fungus or a bacterium.

Such fillings are produced for example by the company ECOVATIVE (http://www.ecovativedesign.com). The products of the company ECOVATIVE is a mixture that includes dried mushroom components and dried cereal halves. This mixture is made to grow with the addition of water and flour in a corresponding object, for example in the frame according to the invention. In this case, the growing fungus adapts to the respective three-dimensional structure of the object, in the sense of the present invention, a mold from the frame and two lids forming the upper and lower surfaces into which the fungus has been introduced. The fungus grows in this form and fills it completely after complete growth.

In addition to the fact that the mushroom components are an ecological filling material, in one embodiment the fungus grown in the frame of the panel element according to the invention has a fire resistance up to a temperature of at least 300 ° C.

In an alternative embodiment, the filler material of the plate member is a transparent material, for example a glass or a polymer, wherein the transparent material is preferably clamped in the frame with a seal, for example a rubber seal.

The plate elements according to the invention can be connected to one another with the aid of connecting elements according to the invention. The connecting elements according to the invention are designed as follows.

In one embodiment of the present invention, each of the contact elements of the connecting element has at least one hole with a center, wherein each hole is surrounded by one of the surface sections. In this case, the hole may either be a through hole or be in the form of a non-through hole.

In a further embodiment of the present invention, the connecting element is configured such that the receiving elements are arranged pivotable about their common connecting line. Such a design allows on the one hand a lot of flexibility in the assembly of the individual plate elements, but on the other hand also simplifies the assembly of the individual plate elements. If, for example, two plate elements are not yet aligned at a desired angle, usually at an angle of 90 °, to each other, it is not necessary first to release a screw in order to carry out the angle correction. On the basis of an above-described embodiment of the surface sections of the plate element and the complementary surface sections of the connecting element, angular correction is possible in a simple manner by pivoting the respective plate element received in the corresponding receiving element about the connecting line.

In one embodiment of the present invention, the surface portion arranged on the inner surface of the contact elements comprises an element of a hook-and-loop fastener. This surface portion represents the surface portion complementary to the plate member, in which, in the case of a hook and loop fastener, the surface portion is, for example, a woven chemical fiber strip having flexible barbs while the complementary surface portion is in the form of a woven buffed synthetic fiber strip. Due to the juxtaposition of these two surface sections a loadable and reversible quick release is provided. The shear forces acting in the direction parallel to the top and bottom surfaces of the plate member are positively received by the hook and loop fastener and prevent slippage of the contact members against the top or bottom surface of the panel member.

In an alternative embodiment, the surface section arranged on the inner surface of the contact elements consists of a tooth structure. This also represents the complementary surface portion to the corresponding surface portion of the plate member. The two surface portions with tooth structures interlock with each other, so that shear forces acting in the direction parallel to the upper and the lower surface of the plate member are positively received and no slippage of the contact elements against the upper or lower surface of the plate member is possible.

In a further alternative embodiment of the present invention, the surface portion arranged on the inner surface of the contact elements is permanently magnetic. As a result, in cooperation with the complementary surface portion of the plate member, there is a magnetic attraction force between the surface portions on the upper or lower side of the plate member and the complementary surface portions on the inner surface of the contact member. The shear forces acting in the direction parallel to the upper and lower surfaces of the plate element are thereby positively absorbed.

In a further embodiment of the present invention, the contact elements of the connecting element are identical to one another. The identical configuration of the individual contact elements of the connecting elements has the advantage that the basic structure of each connecting element, which is composed of a different, even number of at least four contact elements, is always the same due to the identity of the contact elements. The user of the connecting elements as well as the plate elements therefore need not choose between differently constructed connecting elements or purchase them, but can according to his needs connecting elements of identically designed contact elements, i. Connecting elements with the same basic structure, put together. Such an embodiment also leads to a simplified assembly between the individual plate elements and the connecting elements.

In one embodiment of the present invention, at least two contact elements on their outer surfaces on a voltage applied to the connecting line of the contact elements surface portion, so that the at least two contact elements at these surface portions are engageable with each other. In addition to the surface portions on the inside of the at least two contact elements, which can be brought into engagement with the complementary surface portions of plate elements, surface portions are additionally present on the outer surfaces of the contact elements, which abut the connecting line of the contact elements and engageable with a complementary surface portion are. These arranged on the outer surface of the contact elements surface portions allow that a first contact element of a first receiving element with a second contact element of a second receiving element can be connected by the engageable surface portions. As a result, in particular receiving elements of a connecting element, which are aligned at an angle of 90 ° to each other, are held in their vertical position, since a pivoting of the first contact element relative to the second contact element fails due to the brought on the respective outer surfaces of the contact elements surface portions.

With respect to the connection system, which has plate elements as described above In one embodiment of the present invention, the upper surface and the lower surface of the plate member each have one attachment hole per corner, and each of the contact members has at least one hole centered such that the Center points of the holes of the contact elements when receiving the plate member between the inner surfaces of the contact elements of the connecting element substantially coincide with the centers of the mounting holes of the plate elements. Here, the area arranged on the inner surfaces of the contact elements and the respective hole surrounding surface portion is complementary to the surface portion, the respective mounting hole surrounding surface portion of the plate member engaged such that a frictional or positive connection between the engaged surface portions for receiving Shearing forces in the direction parallel to the upper and the lower surface of the plate member.

In one embodiment of the connection system according to the invention, a positive connection between the surface portions on the upper and the lower surface of the plate members and the surface portions on the inner surfaces of the contact elements of the connecting elements is achieved in that the mutually engaged surface portions each comprise an element of a hook and loop fastener. In this case, the barbs of the one element of a hook-and-loop fastener engage in the loops of the other element of a hook-and-loop fastener so that slippage of the plate element against the respective connecting element is avoided and a stable and reversible connection between plate elements and connecting elements is created.

In a further embodiment of the connection system according to the invention, a form-locking connection between the surface sections on the upper and the lower surface of the plate elements and the surface sections on the inner surfaces of the contact elements of the connecting elements is achieved in that the surface portions engaged with each other are in the form of a tooth structure, so that the teeth of the tooth structure on the surface portion of the plate member with the teeth of the tooth structure on the surface portion of the connecting element engage with each other. This avoids that the plate element and the respective connecting element slip against each other, so that a stable, yet reversible connection between plate elements and connecting elements is made possible.

In an alternative embodiment, a frictional connection between the surface portions on the upper and lower surfaces of the plate members and the surface portions on the inner surfaces of the contact elements of the connecting elements is due to the fact that the mutually engaged surface portions are permanent magnetic or ferromagnetic, so that the individual surface portions are connected by a magnetic attraction. The magnetic attraction between the individual surface portions also prevents slippage between plate members and connecting elements and consequently a stable and reversible connection between plate elements and connecting elements. The prerequisite for this is that, in absolute terms, the magnetic attraction force is greater than the acting shear forces.

In one embodiment of the present invention, the mounting holes of the plate members are mounting holes, for example with internal threads or bayonet locks. In this case, holders, for example screws or locking bolts, engage the connecting elements through the holes of the connecting elements and into the mounting holes of the plate elements, such that the holders hold the connecting elements firmly in position relative to the plate element and the connection between the plate element and the reinforce each connecting element. The mounting holes can be designed either continuous or not continuous.

In one embodiment of the connection system according to the invention, the mounting holes of the plate elements are configured continuous and doppelkonisch, with the diameter of the mounting holes respectively from the upper and the lower surface of the plate member to the center between the upper and lower surface decreases, and the holders for the connecting elements at least have a conical head. In such an embodiment, brackets may be screws with a conical head and associated conical nuts.

Other embodiments for mounting holes include threaded holes into which threaded screws are threaded, and threaded cylindrical mounting holes which, in conjunction with a pin, respectively provide reinforcement of the connection between the single plate member and the connector.

In a further embodiment of the connection system according to the invention, the mounting holes are not configured continuously and In each case have a threaded bore in an upper region and in a lower region, so that the holders for the connecting elements with the mounting holes each make a screw connection.

In an alternative embodiment of the connection system according to the invention, the holders for the connecting elements with the mounting holes are firmly connected to one another via a latching mechanism in the manner of a bayonet connection.

In an alternative embodiment of the connection system according to the invention, the holders for the connecting elements and the surface portions surrounding the mounting holes on the upper and lower surfaces of the plate elements are permanently magnetic or ferromagnetic and are connected together by a magnetic attraction.

In one embodiment of the connection system according to the invention, a fastening element, in particular in the form of a furniture foot, a pillar, a roller or a fastening cap, is accommodated in a fastening hole of the plate element. This makes it possible, in addition to screw to reinforce the connection between a single plate member and the corresponding connecting element and other components, such as table legs or chair legs to install in the mounting holes of the plate elements. Such a construction offers a wide variety of applications of the mounting holes with appropriately designed fasteners. Multiple mounting holes can also be used simultaneously in conjunction with mounting caps to attach additional components such as carrying handles, pads, or shields to the panel members. In addition, the mounting holes can be used to attach plate elements to the floor or walls. This underlines in particular the flexibility and versatility as well as the simple assembly of the connection system according to the invention.

In a further embodiment of the connection system according to the invention, the holders for the connecting elements or the fastening elements are equipped with a closure device for avoiding unauthorized disassembly of the connection system. An example of a possible closure device in the context of the present invention is a security key, by means of which individual screw connections of the connection system according to the invention can both be opened and closed.

In a further embodiment of the present invention, a watertight sheath completely surrounds the connection system, the watertight sheath being secured to the surface portions of the individual panel members surrounding the mounting holes. The watertight sheath prevents wetting of the connection system as a whole, i. including the contents of the connection system, which may occur due to transport of the connection system in rain or storage of the connection system in the rain. Furthermore, the watertight sheath prevents contamination of the connection system when it generally comes in contact with liquids. If a waterproof envelope is applied to the inside of the connection system, the connection system designed in this way can serve as a container for liquids.
