The plastic profile has several projections (87) that are formed on base profile, and is made of glass-fiber reinforced polyamide.

Description

State of the art:

Common window concepts can only be improved by increasing the overall depth in their thermal insulation. Currently, the industry is in the process of increasing the current depth from 70mm to 80mm, and there are already the first marketable window systems with 90mm depth.

Large depths of window profiles are extremely demanding during machining (precise cutting, precise joining). In addition, large depths lead geometrically to problems. Because the pivot point is eccentrically mounted on windows, a sash geometrically requires a certain sash width in order to open. The bigger the depth, the bigger the required minimum radius. The wing widths are specified in the redevelopment, so that no windows of the latest generation can be installed here.

Conventional metal window sashes have a sash frame 209 consisting of an inner shell 211, a mandatory outer shell 213 and a multiple glazing 215, which is arranged between the inner shell and the outer shell ( Fig. 1 ). The multiple glazing 215 comprises two or three glass panes 217, 219, which are connected to each other at the edge by means of a spacer 221. To reduce the thermal conductivity of the space 223 between the glass sheets may have a rare gas filling. In this way, multiple glazing can be produced with a thermal conductivity coefficient <0.5 W / m ² K, which are relatively expensive.

This in FIG. 1 shown window is a metal window, in which the inner and outer shell of one or more aluminum profiles 225,227 resp. 229 is formed. Inner shell and outer shell are held together by a glass fiber reinforced plastic seal 231, usually made of polyamide. The polyamide seal 231 is with the aluminum profiles 225,227 resp. 229 form and / or positively connected so that a load-bearing composite structure is created. The multiple glazing 215 rests on a glass support 233, which is supported on the inner shell and the outer shell (profile 229). The glass support 233 may be formed, for example, by a local piece of wood.

Weak point in terms of thermal conductivity is still the wing frame 209, even in modern windows. Here are usually cold bridges, which increase the Gesamtwärmeleitfähigkeitskoeffizienten the sash noticeably. Also sophisticated gaskets with several separate chambers, as in Fig. 1 shown, can not prevent air convection and thus heat exchange. For this reason, the measured u value of such windows varies depending on the mounting position (horizontal or vertical). If deviations from the ideal installation position occur, the u value deteriorates by 30 to 50%.

task

Consequently, there is a need for windows in which the sash has a low U-value and the u-value does not change depending on the installation position. It is also an object of the present invention to propose a window sash, in which even at a small installation depth of about 80 mm, a low u-value can be achieved.

description

These and other objects are achieved by the subject matter of claim 1. Advantageous embodiments of the inventive subject matter are defined in the subclaims.

The invention relates to a window sash with a sash, which consists of an inner shell and an outer shell. A filling, for example a multiple glazing with two, three or more glass panes, is arranged between the inner and the outer shell. Inner and outer shell are thermally separated from each other by an insulation, ie by a region of low thermal conductivity, to heat exchange between the environment and the building interior largely prevent. The insulation, usually in the form of a plastic profile or web, connects the inner and the outer shell.

According to the invention, the inner shell has a profile, in particular a hollow profile, and the insulation is formed as a plastic body with a λ value <0.08 W / m K, preferably <0.06 W / m K and particularly preferably <0.04 W / m K, and the insulation is connected by means of a plastic profile with the hollow profile. This embodiment has the advantage that a significant improvement in the U-value can be achieved in comparison to window sashes with conventional glass fiber reinforced polyamide webs. By using a glass fiber reinforced plastic profile, which is positively and / or positively connected with the plastic body, known and manageable rolling-in techniques can be used for the connection of the plastic profile with the profile of the inner shell. Also, the construction principle of the above-mentioned conventional window does not have to be significantly changed. By using a fine-pored plastic body as a replacement for conventional polyamide webs, significantly lower U-values can be achieved than with conventional polyamide webs.

Advantageously, the plastic profile is connected by means of form and / or material connection with the hollow profile. This has the advantage that known joining techniques can be used to connect plastic profile and hollow profile with each other. Thus, the manufacturers of windows can continue to use their existing joining and curling systems to roll up the plastic connection profiles.

According to a preferred embodiment, the plastic profile has one or more projections molded onto a base profile. These can serve to connect the plastic profile to the hollow profile. Advantageously, at least one leg projecting at an angle, preferably at a right angle, is provided on the base profile. By means of the leg, the connecting surface between plastic body and plastic profiles can be increased, which contributes to a greater stability and carrying capacity of the insulation.

Advantageously, two legs projecting at a right angle are provided. These can provide for a clasp of one end of the plastic body. However, it is also conceivable that the leg or legs do not cling to the plastic body, but added and glued in a slot provided in the plastic body. The legs of the plastic profile have at least a length of at least 5 mm, preferably at least 10 mm and more preferably at least 20 mm. Similar to the conventional plastic webs, the compound plastic profile can be made of a glass fiber reinforced polyamide.

Advantageously, the projection or projections in a groove of the profile are preferably received positively. By means of the projection, the plastic profile can be connected in a known manner with the hollow profile.

A preferred embodiment provides an outer shell, which is formed by a second hollow profile. In this case, the plastic body is attached to the second hollow profile by means of a second plastic profile, e.g. glued or rolled up.

Advantageously, a directed towards the outer shell projection is provided on the profile of the inner shell, which as a support for the filling, respectively. Multiple glazing serves. In this case, the inner glass pane of a multiple glazing is preferably directly or indirectly (via Glasauflager) at least partially on the projection. In this case, the projection may also be extended by the profile of the inner shell, preferably positively connected plastic profile. In such a case, the weight of the filling can be removed via the dimensionally stable, non-compliant plastic profile on the inner shell.

Conveniently, the plastic profile at least partially has a lamination of a synthetic resin. The present in conventional metal windows, glass fiber reinforced polyamide seals are according to the invention are partially replaced by a fine-pored plastic body. It is conceivable that by laminating the fine-pored plastic body can be reinforced so far that the composite material produced can replace the conventional polyamide gaskets in full.

According to an advantageous embodiment, the lamination is provided with a fiber reinforcement. The fiber reinforcement may be formed by a fibrous web, mat, nets, oriented roving strands, mostly unidirectional or non-directional fiber layers, and the like. This can be the Fiber reinforcement be targeted to the expected main stress directions. The fibers of the fiber reinforcement preferably extend for the most part transversely to the longitudinal extent of the profiles. Advantageously, the Laminierng is materially connected to the plastic body. This results in a stable bond between the plastic body and the fiber reinforcement.

Expediently, the lamination is provided on at least one side of the plastic body, namely either at that which is oriented towards the filling or facing away from the filling. By such, at least one-sided lamination, the plastic body can be further reinforced. However, it is conceivable, the lamination on opposite sides of the plastic body, namely on the longitudinal sides, which respectively of the filling. Multiple glazing facing away and provide. Thus, the mentioned longitudinal sides can take the function of tension and compression webs. In terms of production, however, it may also be expedient to provide the plastic body with lamination on all sides or at least on all longitudinal sides.

To achieve the required stability, the lamination may extend at least partially to the inner shell and preferably to the outer shell. Thus, the inner shell and possibly also the outer shell can be positively and preferably positively connected to the plastic body.

Advantageously, the plastic of the plastic body is an expanded polystyrene particle rigid foam, a foamed PET plastic or a PUR material. These plastics have excellent insulating properties and can be produced with the required strength. Conveniently, the plastic may have a specific gravity of <180 Kg / m3, preferably <160 Kg / m3, and more preferably <130 Kg / m3, but at least 80 Kg / m3 (measured according to the current ISO standard 845). The λ value of the fine-pored plastic is preferably less than 0.08 W / m * K, preferably less than 0.06 W / m * K and particularly preferably less than 0.04 W / m * K.

Advantageously, the inner shell, insulation and the outer shell forms a composite structure. For this purpose, the plastic body may be glued to the inner shell and the outer shell and / or rolled or otherwise connected. Conveniently, the plastic body has a thickness of> 15 mm, preferably> 25 mm and particularly preferably> 35 mm.

Advantageously, the inner shell comprises a profile, in particular a metal, wood or plastic profile. A combination of different materials, such as metal / wood, wood / plastic or metal / plastic, is also conceivable.

The insulating material used for the plastic body should have such a compressive strength that it is not compressed when parking the window sash. Accordingly, insulation material with low compressive strength and therefore the better insulation value can be used as insulation material. The inventors have found that in this case, for example, a foamed fine-pored plastic with a compressive strength between 0.5 and 5 N / mm ² and preferably between 1 and 3 N / mm ² and more preferably between 1.4 and 2.3 N / mm ^{2 is} already sufficient. The window according to the invention thus no longer uses polyamide webs. The new construction surprisingly wings with a small depth and a small U-value can be produced. Thus, at a strength of the filling resp. the multiple glazing between 44 and 52 mm a depth of a sash of less than 90 and preferably less than 85 mm, specifically between 78 and 82 mm can be achieved. Thus, the window sash is also suitable for renovations.

According to a preferred embodiment, the support elements, also referred to below as glass supports, are formed by an angle profile. An angle profile has the advantage that one leg can be attached directly to the inner shell, while the other serves as a support for the multiple glazing. The attachment of the one leg to the inner shell can be done by means of screws or gluing or by means of a positive connection.

Preferably, the support element is made of fiber-reinforced plastic, in particular of a plastic from the group of polyamides, polycarbonates, polyethers, polystyrenes, polyethylene, polypropylene, polyamide being preferred. In this case, the plastic may also comprise a proportion of recyclate and / or expandable components. Fiber-reinforced plastic has a low thermal conductivity and can be made with sufficient bending strength, so that such a corner profile the load can accommodate the multiple glazing. Because the angle profile with the outer shell is advantageously not in contact, this does not lead to a noticeable heat exchange. Advantageously, the bending strength of the angle profile is greater than 2 N / mm 2, preferably greater than 4 N / mm 2 and particularly preferably greater than 15 N / mm 2. The legs of the corner profile advantageously have a length of less than 30 cm, and preferably less than 20 cm, and more preferably less than 8 cm. A possible gap between the insulation and the multiple glazing - due to the thickness of the corner profile - can be filled with a sealing profile or a plastic foam.

According to a particularly preferred embodiment, the angle profile is formed as a corner profile, and at least two corner profiles are arranged in two diagonally opposite corners of the window sash. Such an arrangement of the corner profiles achieves a high rigidity of the window sash. Conveniently, the hinge profile in the lower corner of the window sash is arranged on the hinge side. This allows the main load to be derived directly into the hinges. In an advantageous embodiment load-bearing corner profiles are provided in all four corners.

Preferably, a support for the corner profile is provided on the profile. As a result, the load of the multiple glazing is introduced directly into the inner shell Advantageously, a second groove is provided at the front of the profile, in which the second leg of the angle profile is added. When assembling the sash, the corner profile can thus be inserted into the profile of the inner shell.

In a metal wing window, a corner connector in the profile (hollow chamber) of the inner shell is preferably arranged adjacent to the first corner profile. A hinge can be fastened to this, in order to divert the weight of the window sash directly into the window frame.

The invention is also a window system comprising a window sash according to the invention and a window frame with an inner and an outer profile. The inner and outer profiles are analogous to the window sash connected by means of a fine-pored plastic body. To reinforce the fine-pored plastic body at the inner and outer ends in separate Plastic profiles recorded, which in turn are positively connected to the inner and Aussprofilen. Since the structure of the window frame corresponds in essential points to that of the window sash, reference can be made in this regard to the description of the window sash.

The in the FIGS. 2 to 4 shown frame 9 of a window sash has an inner shell 11 and an optional outer shell 13, which are thermally insulated interconnected. Inner and outer shell 11, 13 are formed by metal profiles 15,17, in particular aluminum profiles. The metal profiles 15,17 are connected to each other by means of thermal insulation. The thermal insulation is formed by an insulating material, in particular a foamed, fine-pored plastic body 19, which is received in grooves 21, 23 of the profiles and permanently connected. Preferably, the plastic body is rolled into the aluminum profiles, that is held by undercuts in the grooves 21,23 and optionally glued (s.unten description of the FIGS. 7 to 10 ).

According to a first embodiment of the invention, the weight of a multiple glazing or other filling is removed only on the inner shell and possibly on the frame corner of the inner shell. For this purpose, according to one embodiment, a first corner profile 25 is provided, which is attached to the inner shell and / or is supported on this. According to the preferred embodiment shown, the corner profile 25 with the two legs 24, 26 arranged at a right angle to one another is produced from an angle profile 27. The angle section 27 has in cross section a first leg 29, which serves as a support or stop for the multiple glazing (in the Fig. 2 to 4 not shown), and a second leg 31, which is positively received preferably in a groove 33 of the profile 15. A projection 35, which is provided at a distance from the free leg 37 of the groove 33, serves as a support for the angle profile leg 29. It is important that the projection of the thigh plane by a certain amount, preferably by at least 5 mm and more preferably in order protrudes at least 10 mm, so that the main weight of the filling can be removed on the bridge. The distance between the end face 39 of the groove 33 and the projection 35 preferably corresponds to the thickness of the leg 29. However, a shorter leg 37 is conceivable, as long as it is ensured that the weight of the multiple glazing is substantially completely dissipated to the inner shell 11. Advantageously, the groove has a depth of at least 10 mm and preferably at least 15 mm. The fact that the corner profile 25 extends around the corner of the sash frame, results in a particularly rigid construction.

For stability reasons, a corner connector 41 is provided adjacent to the corner profile 25, which is received in a hollow chamber 43 of the profile 15 ( Fig. 3 ). The corner connector 41 is preferably a stable square profile with strong walls, so that a hinge 45 by means of appropriate screws, rivets or the like (not shown in the figures) can be attached thereto (s. Fig. 4 ).

Below the hollow chamber 43, a fitting groove 44 is provided which serves to receive conventional fittings. To the building inside wall of the profile 15 includes a web 46, at its free end a sealing groove 48 is provided for receiving a plastic seal.

In the FIGS. 5 and 6 the corner profile and the corner connector are shown in more detail in detail. When corner profile 25 is important that this has the smallest possible thermal conductivity coefficient. It is therefore preferably made of a fiber-reinforced plastic. As reinforcements come glass, carbon, natural, aramid fibers and fibers with similar properties in question. The stiffness of the corner profile can be increased by appropriate orientation of the fibers in the longitudinal direction of the legs 29,31 and by the use of rovings. Preferably, the length of the leg 29 is selected so that no contact between the corner profile 25 and the outer shell 13 is made. Also, between the corner profile and the insulation 19, a small air gap of 0.5 to 5 mm, preferably 1 to 2 mm may be present. Preferably, however, there is no gap between the insulation and the side surfaces of the multiple glazing or filling.

A corner profile 25 is preferably provided at least in two corners of a window sash. It may for example be provided in the two lower corners of a window sash or in two diagonally opposite corners of the sash. In the second variant, a corner profile is preferably to be arranged on the hinge side in the lower corner.

The embodiment according to Fig. 7 shows a metal window in section. The multiple glazing consists of a triple glazing with an interior

Glass pane 45, a middle glass pane 47 and an outer glass pane 49, which disks are spaced apart by spacer blocks 51. In order to compensate for size tolerances of the multiple glazing in length, width and thickness, compensation elements 53, such as leveling lumber, can be provided. It can be seen that the multiple glazing - separated only by a narrow sealing strip - rests on the profile 15. The distance between multiple glazing and the free leg 37 is preferably less than 8 mm and more preferably less than 5 mm. In this case, the leg 29 should project in each case by more than the distance of the inner glass pane 45 from the free leg 37 from the plane of the free leg. As a result, the greatest part of the weight of the filling resp. the multiple glazing on the leg 29 are removed.

In the outer profile 17 a serving as a weather protection profile 57 is inserted in a groove 55. At the upper end of the profile, a seal 59 is provided, which seals the outer shell and the outer glass pane 49 against each other.

A window frame 61 serving as a window frame 61, which also has a core 63 made of foamed plastic, serves as a stop for the window sash. The plastic core 63 is firmly connected to an outer profile 65 and an inner profile 67. An inside profile on the outer profile 65 arranged sealing profile 69 serves to seal a existing between the plastic body 19 and the plastic core 63 gap 64. The wall connector part 61 is in the reveal of a window opening (not shown in the figure) posted and attached.

The embodiment according to FIG. 8 differs from the window according to FIG. 7 in that the window frame 61 and the inner shell is partly made of wood on the room side. The inner shell 17 consists of a wooden profile 70 in which a metal profile 72 is received in a fold 71. The metal profile 72 is fixedly connected to the plastic body 19 and the outer shell 13. The metal profile 72, like the profile 15 has a groove 33 which serves to receive the angle profile leg 31. In the interaction of groove 33 and projection 35 results for the inserted corner profile 25 a form fit with little play.

The embodiment according to Fig. 10 is characterized in that a window sash is combined with a fixed glazing. Incidentally, the structure is the same as the sash of Fig. 7 ,

In the FIG. 9 is shown a double window sash whose sash can be opened in the same or opposite directions of rotation. At the casement, which is in the illustration below, a middle cuff 73 is arranged, on which abuts the upper wing. Incidentally, this embodiment corresponds to the one already described, so that it need not be discussed in more detail.

According to one embodiment of the invention ( FIG. 11 ) As insulation, a plastic body 19 is provided, comprising a fine-pored, dimensionally stable and substantially pressure-resistant insulating material of a material as described above, which plastic body 19 is connected by means of two plastic profiles 78,82 with the inner and outer shell 11,13. The plastic profiles 78,82 are U-shaped in cross-section and have two legs 80,84 formed on a flat base profile. The legs 80,84 of the plastic profiles 78,82 are preferably connected by means of an adhesive bond cohesively with the plastic body.

Optionally, the plastic body may include a lamination 74 of a synthetic resin and a fiber reinforcement (in FIG. 11 not apparent). In the exemplary embodiment shown, the lamination 74 is provided only on the longitudinal side 75 facing the filling 76 (here: multiple glazing) and / or the side 77 facing away from the filling 76. It is conceivable, however, that the lamination 74 is provided at least on all longitudinal sides of the plastic body 19. Advantageously, but not necessarily, the lamination extends into the grooves 21 of the metal profile 15 and preferably into the grooves 23 of the metal profile 17, where by undercuts 79 respectively. 81, which can be formed by rolling, a positive connection is realized.

So that the plastic body 19 can withstand the necessary carrying capacity and also in the longitudinal direction of a large traction force, the plastic body is partially covered by the plastic profiles 78, 82. The plastic profiles are designed to U-shaped and have lateral legs 80,84. The legs 80,84 include the ends of the plastic body 19 at least partially. To the Plastic profiles 78,82 heads or projections 87,89 are formed, which are positively received in the grooves 21,23 with the undercuts 79,81.

Like the window sash according to the invention, the window frame 61 also has a preferably laminated plastic body 93. The plastic body 93 may consist of the same material as the plastic body 19. The plastic body 93 is at least partially encompassed at the ends of two U-shaped plastic profiles 100,102 in each case. The plastic profiles 100,102 have molded-on projections 103,105, which are rolled into corresponding grooves 95,99 of the profiles 65,67. The profile 65 has for this purpose grooves 95, the side walls form undercuts 97. Likewise, the profile 67 grooves 99, the side walls form undercuts 101. Accordingly, the projections 103, 105 of the plastic body 93 are positively held in the grooves 95,99.

It is conceivable to provide only one or more than two grooves 95.99 in the profiles 65, 67. In order to achieve a firm connection also with respect to forces acting in the longitudinal direction of the profiles, the side walls 107, 109 are glued at least in areas and preferably substantially over the entire surface to the inner surfaces of the profiles 65, 67.

To achieve the lowest possible U-value of the whole or at least the largest part of the Falzraumvolumens between the window sash and the window frame is preferably filled by a sealing body 111. A special feature of this window construction is that over at least half and preferably over at least 2/3 of the thickness of the plastic body 19 of the sealing body 111 on the plastic body 19, respectively. Plastic core 93 is applied or only a minimum gap of less than 3 mm, and preferably less than 1 mm releases. By this novel seal, which represents an independent aspect of the invention, a heat exchange in the space between the sash and the window frame can be largely prevented.

The sealing body 111 may be a co-extruded sealing profile having a first portion 113 of a first plastic and a second portion 115 of a second plastic. The second plastic is preferably an elastomer, for example based on olefins or urethanes, or a thermoplastic polyamide. The second Section 115 of the sealing body advantageously has a plurality of chambers 117 arranged one behind the other, which fill in their area the space between the casement and the window frame.

The sealing body 111 is on the one hand received in a form-fitting manner in a groove 67 provided in the profile groove 119 and on the other hand in a groove 121.

The embodiment according to Fig. 12 is different from that of Fig. 11 essentially in that the plastic bodies 19, 93 have a different geometric shape. Here it is shown in particular that between the inner and the outer shell 11,13 next to the plastic body 19 still another insulating material, which has an even lower lambda value than the material of the plastic body 19, may be provided. According to the embodiment shown, the plastic body 19 integrated in the sash has a channel extending in the longitudinal direction or a recess 122, in which a second insulating material 127 is accommodated. This may likewise be a foamed plastic or, for example, an airgel. Also, the filling 76 may be supported in the form of multiple glazing on a glass support 123 made of the second or other insulating material. In between, a so-called. Falzraumfüller, for example, a sponge rubber, be arranged to prevent convection of the air as possible.

The inner and outer profiles 65,67 of the window frame according FIG. 12 are held together by two plastic body 93. The lateral edges of the plastic body 93 are each received in plastic profiles 125, which surround the plastic body 93 with the legs 129 partially. The legs 129 preferably have at the end an inwardly oriented bead 130 which can engage in a longitudinal groove in the plastic body or can simply be pressed into the plastic body 93. As a result, a positive connection is realized which prevents removal of the plastic profile 125 from the plastic body 93 or at least counteracts such. Between the two plastic bodies 93, an insulating material, hereinafter referred to as insulation body 131, is provided, which has a lower lambda value than the plastic body 93. Because the plastic bodies 93 have sufficient stability and strength, the insulating body 131 can be optimized in terms of insulating properties, so that the Heat transfer can be further reduced, because in general a higher strength of the insulation material is associated with poorer insulation properties.

The plastic profiles 125 each have a molded-on head or projection 133, which is rolled into a groove 135 of the inner and outer profiles 65,67. The projection 133 is formed as a cone, so that this, once it is rolled into the aluminum profile, is held by a positive connection.

In FIG. 13 is the plastic profile 125, whose essential features are identical to the features of the plastic profile 78, shown by way of example in an enlarged scale. The following description therefore also reads on the plastic profile 78 and the plastic body 19. In order to prevent the plastic body 93 from tearing out, a sawtooth-like elevation 137 is provided at the end of the limb 129. This sawtooth-like elevation 137 can be buried in the surface of the plastic body 93 and thus counteract a tearing of the plastic body 93 from the clasping of the legs 129.

FIG. 14 shows that the inner surfaces of the legs 129 may have a corrugation 139. The corrugation 139 has the purpose, on the one hand between the legs 129 and the plastic body 93 to achieve a positive connection, and on the other hand to provide an enlarged surface for an adhesive connection between the legs 129 and the plastic body 93.

The embodiments of the plastic profiles 125 according to the FIGS. 15 and 16 show further variants of how a positive connection between plastic profile 125 and plastic body 93 can be achieved. According to FIG. 15 are cuts 41 provided in the legs 129. The cut parts 143 are then pressed into the plastic body 93 such that a positive connection is realized.

The embodiment according to FIG. 16 then differs from that of FIG. 15 characterized in that only incisions are made in the legs 129, so that from the plane of the legs herausschwenkbare material parts 145 are formed, which, however, remain connected to the leg. Shown are in the FIG. 16 U-shaped cuts 147 in the legs 129, which are designed so that the material parts 145, when pressed into the plastic body 93, Prevent a withdrawal of the plastic body 93 from the clasp of the plastic profile 125 or at least counteract.
