Description

The present invention relates to a composite profile for doors, windows or facade elements according to the preamble of claim 1.

Composite profiles of the above type are known and have been used successfully for a long time. A feature of such composite profiles is the shear strength of the composite, i. that the sub-profiles, which form a frame profile together with an insulating web, can not be displaced relative to each other in profile direction or longitudinal direction.

In the DE 29 37 454 C2 is a composite profile described, which is characterized by a positive connection between the metallic sub-profiles or shells and the insulating web. This is achieved by a metallic insert forming a positive fit, so that displacement in the longitudinal direction can be prevented. Such a connection is referred to as shear-resistant.

In practice, however, has shown that sets a different bimetallic effect by different thermal expansion of the inner and outer shells of a frame profile. This means that the individual sub-profiles or shells warp in the plane of the frame profile and thus can lead to leaks. This is particularly the case with doors that are exposed to sunlight.

To fix this problem, was in the EP 0 829 609 A2 proposed a so-called non-impact compound. Thereafter, the connection between the insulating web and metallic partial profile or shell is designed so that a displacement in the longitudinal direction is possible. This displacement in the longitudinal direction can take place both between the insulating web and the metallic part profile or the shell, as well as between two parts of an assembled from these parts insulating bar (which preferably consists of plastic).

A disadvantage, however, is that an insulating web is arranged in a composite profile according to the prior art, although in a rebate region of the composite profile, as for example, between a frame and a movable relative to the frame Wing frame is formed in the closed or locked state of the sash, a possibility for positioning and attachment of folding elements, such as sealing profiles but not given and therefore positioning and mounting options in the rebate area in other ways and, consequently, often complex and thus created expensive Need to become.

The invention therefore has the object to at least partially overcome the above problems.

The present invention solves this problem by the subject matter of claim 1.

The invention also provides a window or door or façade element having at least one or more composite profiles according to any of the claims appended hereto. Advantageous embodiments of the invention are specified in the subclaims.

According to the characterizing part of claim 1, it is provided that in a separation zone with a sliding guide between two Isolierstegabschnitten the at least one insulating bar or the plurality of insulating bars, a groove is arranged, in which a foot of a folding element can be used.

Thus, a composite profile is provided in which in a simple and thus advantageous manner to narrow space in the folding area, e.g. a possibility is created between a frame and a relative movable sash, folding elements, such as e.g. to position or fasten a sealing profile.

Advantageously, the groove has an undercut cross-section. Thereby, the folding elements inserted into the groove, such as e.g. the foot of a sealing profile easily and thus advantageously positioned or secured by a positive snap connection.

According to a particularly preferred embodiment of the invention, the groove is disposed within the insulating strip (s) between two parts thereof. Thereby Advantageously existing extrusion dies for the metallic profiles of the composite profile can be used.

It is also particularly preferred that the surface of the insulating bars is made flat, so that no protruding parts hinders the installation of further folding elements. In addition, such insulating bars can also be particularly easily formed.

Further advantageous embodiments of the invention can be found in the dependent claims.

The Fig. 1 shows a door 1, which has a sash 2 and a frame 3. This is merely an example to understand. Alternatively to the in Fig. 1 1, the present invention can also be applied to windows or other components.

If the frame 3 set in the masonry or other construction, the bending stresses occurring in the masonry or other construction are introduced via the fastening means. A bending load in the frame 3 usually does not occur. In this case, a thermally insulated composite profile 4 according to the invention is used only for the production of the wing frame bars 5, 6 of the door 1.

By a corner joint of these vertical wing frame bars 5, 6 with an upper horizontal wing frame spar 7 of the profile composite according to the invention of the vertical wing frame bars 5, 6 is provided in a U-shaped frame with a fixed point. The resulting due to a temperature difference length expansion of metal profiles of the vertical sash frame beams 5, 6 can thus be done freely to the underside of the U-shaped sash 2. The upper horizontal door frame spar 7 can thus be designed in conventional, shear-resistant composite technology. Is the frame 3 of this door 1, but as in the Fig. 1 additionally shown, provided with side parts 8, 9, it may be necessary to manufacture both vertical frame frame members 10, 11 from inventive, thermally insulated composite profiles 4.

In Fig. 2 an inventive composite profile 4 is shown. This composite profile 4 can be used as a sash profile as part of a sash 2 or window frame 3 for doors 1, windows or other components, so that the The following description refers equally to sash profiles and frame profiles.

In the following, a composite profile 4 with two metallic outer profiles 12, 14 and a metallic center profile 16 will be described purely by way of example. Alternatively, the composite profile 4 may be constructed without metallic center section 16, so that in the case the two metallic outer profiles 12, 14 are connected to each other via at least one insulating web. In practice, such a construction of a composite profile 4 with two metallic outer profiles 12, 14 described here as an alternative - here merely for editorial reasons - has hitherto been encountered more frequently than the structure with an additional metallic center profile 16.

The composite profile 4 has a first metal profile, an outer profile 12, in which here at least one hollow chamber 13 is formed, and a second metallic outer profile 14, in which also preferably at least one hollow chamber 15 is formed. Between the two metal profiles 12 and 14, a third metal profile, a central profile 16, is arranged, in which also preferably at least one hollow chamber 17 is formed.

The metallic profiles 12, 14, 16 may alternatively be designed without pronounced hollow chambers 13, 15, 17 or have a plurality of hollow chambers.

The first metallic outer profile 12 is connected to the metallic center profile 16 via at least one or more first insulating webs (aligned parallel here) 18. These insulating webs 18 between the first metallic outer profile 12 and the metallic center profile 16 form a first insulating land zone I or plane.

The second metallic outer profile 14 is also connected to the metallic center profile 16 via at least one or more second (parallel here) insulating bars 19. The insulating webs 19 between the second metallic outer profile 14 and the metallic center section 16 form a second insulating land zone II or plane.

The first and second insulating webs 18, 19 have here, by way of example, no hollow chamber. Alternatively, the insulating webs 18, 19 but also one or more Have hollow chambers or the first or the respective second insulating webs 18, 19 may be summarized by transverse webs to a kind of superior insulating profile.

The insulating webs 18, 19 of the Isolierstegzonen I, II are here-purely exemplary- in a plane. Alternatively, it is also possible that the insulating webs 18, 19 of the Isolierstegzonen I, II are each offset vertically and or horizontally to each other and / or arranged inclined.

The first and second metallic outer profile 12 and 14 and the metallic center profile 16 are preferably made as extruded aluminum profiles. Alternatively, the production is also possible from a different material such as steel and / or another manufacturing method. The insulating webs 18 and 19 are made of a plastic material, such as plastic. Polyamide, prepared so that each a substantial thermal separation between the metal profiles 12, 14, 16 is achieved.

Preferably, the insulating webs 18 and 19 are web-shaped in cross-section and have thickened end portions 20. Preferably, each of the end portions 20 engages in a corresponding groove 21 of each one of the metal profiles 12, 14, 16, wherein the groove walls, the thickened end portions 20 of the insulating webs 18, 19 in the x and γ direction (see coordinate system in Fig. 2 ) preferably engage positively. The respective end portion 20 preferably has a trapezoidal or triangular or wedge-shaped or L-shaped or rectangular cross-section. The respective groove 21 accordingly has a cross section with a corresponding cross section.

The respective end portion 20 of the insulating web 18, 19 is preferably additionally in the z-direction (see coordinate system in Fig. 2 ) positively connected to the respective groove 21. This is realized in an advantageous manner by a forming process and / or by a wire 22 having an outer structure, such as knurling. Alternatively, the end sections may be inserted into the groove 21 without wire or the like.

In Fig. 2 has -here purely exemplarily- in the second Isolierstegzone II, the second insulating webs 19, whose respective end portions 20 are positively and non-positively connected to the respective groove 21, so that in each case one in particular in the z-direction (see coordinate system in FIG .) And in a direction orthogonal to the cross-sectional plane of the composite profile 4 shear-resistant connection between the second insulating bars 19 and the adjacent outer and middle metallic sub-profiles 14, 16 results.

The shear strength of the other - here the first - Isolierstegzone I is in contrast lower than that of the first insulating land zone II in all variants. It is chosen such that a displacement of at least two elements in the Isolierstegzone relative to each other due to dilation is possible.

The invention is based on the in Fig. 2 illustrated variant is not limited, but also on a composite profile 4 feasible, in which only two metal profiles 12, 14 (inner profile and outer profile) are connected via a single insulating land zone with one or more insulating webs 18.

In Fig. 2 respectively. Fig. 3 It is shown that the insulating webs 18 of the first insulating land zone I between the first metallic outer profile 14 and the metallic center section 16 have two insulating web sections or partial sections 18a, 18b or parts which are movable relative to one another. Preferably, a separation zone is formed between the subsections 18a, b, in which a thrust-free sliding guide allows a relative movement. But it is also conceivable that between the sections of the insulating bars 18 cross-connections are formed, which in turn are designed such that the sections are movable relative to each other (not shown).

The two sections 18a, b of the insulating webs 18 are in the y- and x-direction (relative to the coordinate system in Fig. 2 ) positively connected by a Kederverbindung. A first section 18a of the insulating web 18 has a Kederwulst 24 and a Kederfahne 25. The other, second section 18b, however, has a groove 26 with corresponding cross-sectional geometry, so that the Kederwulst 24 engages in the groove 26 and the Kederfahne 25 is led out of the groove 26. In this way, a sliding guide is formed. The shear strength in the Slide can orthogonal to the cross-sectional plane of the composite profile, but must not go to zero.

With respect to the xy plane (see coordinate system Fig. 2 ) or in a plane orthogonal to the profile direction of the metallic outer profiles 12, 14 and the metallic center section 16 parallel or spaced from the Kederverbindung or sliding, the insulating web 18 has a groove 27 with here undercut cross-section. In the groove 27 engages a foot 28 of a sealing profile 29 here, which forms a sealing lip 30 here. The sealing profile 29 or the sealing lip 30 serves, for example, for sealing a rebate space, as in a structure with a frame 3 and a relative to the frame 3 movable sash 2 between the profile beams 5, 6, 7, 10, 11 in the closed or locked Condition of the sash 2 between the frame 3 and sash 2 is formed.

The groove 27 is in an embodiment of the invention in different ways, as well as the following figures show, that is arranged in a separation zone between sections of the insulating bar 18 in thrust-free execution.

The term "separation zone" is to be understood such that the groove 27 does not have to be arranged centrally to the dividing line of the sliding guide, so that a quasi-continuous dividing line results, but can also be arranged so that a dividing line results, the one or bent several times by 90 °, so that a separation zone is formed through which the dividing line passes.

The groove 27 is designed and arranged such that a folding element, such as a sealing profile 29, or its foot 28, heat-insulating wedges, glass blocks or other profile strips can be securely positioned or fastened. A groove 27 with undercut cross-section offers, for example, as in Fig. 2 or 3 shown the possibility in the form of a snap connection between the groove 27 and the folding element.

Accordingly, the representation as a groove 27 with an undercut cross section in the following figures is purely exemplary, so that the groove 27 may also have other cross-sectional geometries, the secure positioning and the safe Allow attachment of the folding element advantageous according to the form-fitting principle.

The first metallic outer profile 12 is separated from the metallic center profile 16 preferably via a hollow chamber 33 which is formed in the first insulating land zone I between the two first insulating webs 18 and the adjacent metal profiles, while the metallic center profile 16 of the second metallic outer profile 14 via a Hollow chamber 34 is separated, which lies in the second insulating land zone II between the second insulating webs 19 and the adjacent metal profiles. As a result, from a outer side of the first metallic outer profile 12 to a second outer side of the second metallic outer profile 14, a plurality of hollow chambers 13, 33, 17, 34 and 15 are formed, which ensure good thermal insulation. The two metallic outer profiles 12, 14 have on each opposite sides outwardly projecting webs 35 and 36, wherein at the end of the web 35 a groove 37 for receiving a seal and on the web 36, a further groove 38 is provided for receiving a seal.

Thereby, a composite profile 4 is provided, which provides the possibility, in the fold region between the frame 3 and casement 2 in a simple and advantageous manner folding elements, such. a sealing profile 29 and its foot 28 in a limited space to position or fasten.

The insulating bars 18 according to the invention particularly preferably form a planar surface XX with at least one of the metallic profiles 12, 14, 16, but at least one flat surface XY with adjacent parts of the metallic profiles 12, 14, 16.

In order to avoid repetition, only deviations or changes and additions to the above-described embodiment variant of an insulating web 18 according to the invention will be described below Fig. 2 respectively. Fig. 3 described.

Fig. 4 shows a variant similar to Fig. 3 without inserted sealing profile 29. In addition, here protrudes a web 31 on the one metal profile 12 and 16 to the opening area the groove 27 and thus additionally secures an inserted into the groove 27 folding element against falling out.

In Fig. 5 a further embodiment of the invention is shown. Deviating from the embodiment according to Fig. 3 Here, the groove 27 is designed with an undercut cross-section as a groove 27 with a T-shaped cross-section. Consequently, the foot 28 of the inserted seal 29 is also T-shaped and also has a hollow chamber 39. In addition, both sections 18a, 18b of the insulating web 18 are led out of the groove 21 forming zones of the respective metal profile 12, 14, 16, so that the insulating web 18 here at least no continuous plane XX with the groove 21 forming zones of the respective metal profile 12th , 14, 16 forms.

In the 6 and 7 In each case, a thermally insulated composite profile according to the prior art is shown.

The composite profile after Fig. 6 has in each case a shear-resistant insulating web 19, which has no possibilities, folding elements, such as seals to position and / or attach to him.

The composite profile after Fig. 7 has a shearless insulating web, the two sections form a Kederverbindung, however, in each case or together have no opportunities to position and / or fix folding elements, such as seals on the insulating bar or on the sections of the insulating strip.
