Description

 Composite profile for window, door or facade elements and insulating bar for such a composite profile

The invention relates to a composite profile for window, door or facade elements and an insulating web for such a composite profile.

Thermally insulated composite profiles for window, door or facade elements and insulating webs for such composite profiles are known in the art. WO 97/09504 Al discloses such a composite profile and such an insulating web for such a composite profile, each extending in a longitudinal direction. The insulating bars are designed as hollow chamber webs. In these hollow chamber webs hollow chambers extend in the longitudinal direction, i. such that in a cross section perpendicular to the longitudinal direction, the hollow chambers have a closed cross section. The insulating bars are connected to the profile parts by rolling. Such hollow chamber webs with one or more hollow chambers are also known from the brochure "Standard Profiles 2012" of the TECHNOFORM BAUTEC, eg the standard profile with the article number 299000 shows a hollow chamber profile with a hollow chamber and the hollow chamber profile with the article number 384200 shows a hollow chamber profile with three hollow chambers Insulating webs with a hollow chamber profile are known from DE 42 38 750 A1, which is referred to as state of the art in WO 97/09504 A1 In DE 42 38 750 A1, the multi-chamber hollow profiles are produced from two parts with different wall thicknesses and, for example, welded.

From EP 1 580 388 A2 and DE 10 2009 023 883 Al each Isolierstege with individual hollow chambers are known, which are assembled from two Isolierstegteilen. The two Isolierstegteile are designed so that the respective curl body are formed in two parts for rolling in grooves of the profile parts and can be plugged together. After curling the mating Isolierstegteile are held relative to each other in position. The recesses and projections for mating lie on a parting plane which runs centrally through the curl body and is located after the mating in the interior of the curl body.

Elongated hollow sections are known from EP 0 584 467 A1, which consist of at least two partial profiles which are extruded separately and are then joined together. From WO 2008/1 19535 AI insulating strips for composite profiles, window, door or facade elements are known which extend in a longitudinal direction and in which the Isolierstegkörper by the wall (s) of the Isolierstegkörpers continuous recesses, which by ladder rung-like webs from each other are separated. This ladder-like design allows limited longitudinal displacement of the profile parts. The insulating web has a cover which is formed integrally with the Isolierstegkörper and can be clipped to the Isolierstegkörper and completely covers the recesses in the clipped state.

FR 2 604 739 A, EP 2 136 024 A1, WO 2011/050954 A1 and WO 2012/000652 A1 each disclose further composite profiles and insulating webs.

It is an object of the invention to provide a composite profile for window, door or facade elements and a Isoliersteg for that allow for simplified manufacturability to securely connect after the production to be joined subregions.

This object is achieved by an insulating web according to claim 1 or a composite profile according to claim 11.

Further developments of the invention are specified in the dependent claims.

The integrally formed insulating web with a plurality of hollow chambers allows a simple and therefore cost-effective design of the tool and at the same time a secure connection of its sections by the clip connection, which is located in the rolled state between the groove limiting Anpress- and stop strips and thereby kept in engagement.

This design also allows for easy filling of one or more of the hollow chambers with foam.

This embodiment is particularly preferred in hollow chambers whose extension in the height direction is <_10 mm. Other features and advantages of the invention will become apparent from the description of exemplary embodiments with reference to FIGS. From the figures show:

The features of composite profiles and hollow chamber profiles which are known in the prior art and are present in the embodiments described here will first be described with reference to FIGS. 1 to 3.

In Fig. 1 is a cross-sectional view of a composite profile is shown, which extends in a longitudinal direction Z. The composite profile has two profile parts 31, 32, which are separated by a predetermined distance in a transverse direction X, which is perpendicular to the longitudinal direction Z. The profile parts 31, 32 are usually formed as metal profiles and preferably as aluminum profiles. The profile parts 31, 32 are sheared by Isolierstege 10 'in the longitudinal direction Z and held in the transverse direction X at a distance and in a vertical direction Y perpendicular to the longitudinal direction Z and the transverse direction X relative to each other in position. In the composite profile 1 shown in FIG. 1, a cavity 1 h is limited by the use of the two insulating webs 10 'and the profile parts 31, 32. In other composite profiles, not shown, only one Isoliersteg 10 'for connection of the profile parts 31, 32 may be provided.

2, the conventional insulating web 10 'shown in Fig. 1 is shown enlarged. The insulating bar 10 'extends in the longitudinal direction Z and in the transverse direction X over a predetermined width B and in the height direction Y over a predetermined height H. The insulating bar 10 'has at its opposite in the transverse direction X outer edges (longitudinal edges) 21, 22 each a curl body 25. Such a curl body 25 is formed as a bar complementary to the groove 31g, 32g, which extends in the longitudinal direction Z and has a predetermined cross-section perpendicular to the longitudinal direction Z. In the embodiment shown in FIG. 2, a recess 25k for an adhesive cord is provided on the respective outer sides. Such an adhesive cord recess 25k is optional and may be omitted.

The insulating web 10 'has the width B in the width direction X, wherein the curl body 25 each have a dimension b2 in the width direction X. This dimension b2 will be explained in more detail with reference to FIG. The insulating bar 10 'has a height H in the vertical direction Y, wherein the hollow chambers 1 have a height (inner height) h in the vertical direction Y. For Isolierstege 10 'of the type shown, the height h of small hollow chambers is 10 mm or less.

In Fig. 3, the configuration of the grooves 31 g, 32g and the curl body 25 and the Anpressleisten 33 and stop strips 34 is shown in more detail. To simplify the explanation, a conventional insulating bar 10 "is shown The description of the configuration of the grooves 3 1 g, 32g and rolling body 25 and of the curling is similar to that of Figures 1 and 2. The groove 31 g, 32g, has a dimension ( Groove depth) bl in the width direction X, which is determined by the height of the lower strips 33, 34 in the transverse direction X. The lower of the strips 33, 34 is usually the stop strip (often also called anvil or shoulder) 34. 3) is deformed by the plastic deformation into the position indicated by 33e in FIG designed so that the most protruding projection of the hammer 33 in the position 33 e is spaced approximately as far in the transverse direction X from the bottom of the groove 31 g, 32g, as the s corresponds to the measure bl.

The groove 31 g, 32 g facing flanks of the pressure bar 33 and the stop bar 34 are usually inclined so that the groove narrows in the transverse direction X away from its bottom. The curl body 25 has a cross section XY perpendicular to the longitudinal direction Z has a correspondingly adapted cross-section (here trapezoidal shape), so that a kind of dovetail connection is formed. Before deforming the Anpressleiste 33 sufficient clearance for insertion of the curl body 25 in the longitudinal direction Z is present in the groove. After deforming the Anpressleiste 33 in the designated 33e position of the curl body 25 is pressed between the Anpressleiste 33 and the stop bar 34 and held so shear resistant. This process and this design of the grooves and the rolling body is basically known. The standard Technoform groove is shown in the "Standard Profiles 2012" catalog on page 22 with dimensions, for example, the dimension bl is 2.5 mm, and in other configurations of the groove 31 g, 32 g, not shown here Measure bl accordingly functionally determined so that the relevant for the shear-resistant clamping of the curl body measure is determined.

The curling body 25 with the complementary dovetail shape usually has a dimension b2 in the transverse direction X which is approximately equal to the dimension bl, preferably slightly larger than the dimension b2. Depending on the shape of the groove and other events, the dimension b2 of the curl body 25 may also be larger or smaller than the dimension bl. Again, in each case, the measure b2 is functionally determined by the fact that it depends on the interaction of the groove and the curl body for shear-resistant holding the insulating web in the groove. Thus, for a dimension bl of 2.5 mm, the dimension b2 of the curl body 25 will usually be 2.5 mm or a little more, e.g. 2.6, 2.7, 2.8, 2.9 or 3.0 mm.

Referring again to Figs. 1 and 2 and the conventional Hohlkammerisoliersteg 10 'shown there, close to the curl body 25 each wall sections 10-4, which limit the hollow chambers 10h in the direction of the curl body 25. In height direction Y, the hollow chambers are each bounded by wall sections 10-2 and 10-3, which adjoin the wall sections 10-4. In the embodiment shown in Fig. 1, 2 with two hollow chambers, a partition wall 10-1 is provided between the two hollow chambers 10h.

The features of the composite profiles and insulating webs described above with reference to FIGS. 1 to 3 also apply to the embodiments of the invention described below, with the exception of the described differences of the embodiments. the same Reference numerals denote the same elements / features and the description is not repeated for reasons of simplicity.

4, a first embodiment of an insulating web 10 and a corresponding composite profile according to an embodiment of the invention is shown. In view a) is shown a cross-sectional view in which the constructive difference to the conventional insulating webs 10 'of Fig. 1, 2 is clearly visible. In the area of the curl body 25 are each clip connections 27, 28 are provided, by means of which pivotable wall portions 29 of the hollow chambers 10h limiting wall 10-3 (or 10-2) are clipped to the Isolierstegkörper 20 of the insulating 10. The remaining elements and components of the insulating strip 10 correspond to those of the insulating strip 10 'of Fig. 2 and are designated by the same reference numerals, so that the re-description is omitted here for the sake of simplicity.

As can be clearly seen in view b) in FIG. 4, the pivotable wall sections 29 can be pivoted away from the opposite wall 10-2 by bending joints 29g. As can be clearly seen in FIG. 4 b), the wall 10 - 2 (the wall of the insulating web extending essentially in the longitudinal direction Z and transverse direction X) can also consist of sections 29 which can be pivoted about bending joints 29 g. The bending joints 29g need not necessarily be formed exactly at the connection to the partition 10-1, but the bending joints can also be formed by appropriate elastic deformability of the walls 10-1, 10-2, 10-3 itself.

In any case, as can be seen clearly from a comparison of FIGS. 4a) and 4b), the wall 10-1, 10-2, 10-3, 10-4 of the hollow chambers 10h, which is completely closed in the clipped state, can be opened by opening the clip connection 27, 28 open.

The clip connection 27, 28 itself is formed by a clip recess 27 on the outside of the curl body 25 and a corresponding clip device (clip projection) 28 at the free end 29 e of the pivotable wall sections 29 opposite the bending joint 29 g. The term clip connection is to be understood in this application that all connectors that hold the sections 27, 28 closed up to a predetermined counterforce should be detected. Preferably should be recorded clips, plug or Snap-on connections, in which this holding force is generated by utilizing the elasticity of the material of the insulating web.

The corresponding clip connection 27, 28, i. the recess 27 having the outer side of the curl body 25, in the rolled-up state, either the Anpressleiste 33 (see Fig. 4 c)) or the stop bar 34 (see Fig. 4 d)) facing. This located in the height direction Y on the outside of the curl body 25 recess 27 and the matching clip device 28 allow that in the rolled state, an opening of the clip connection 27, 28 is made impossible (see Fig. 4 c) and 4 d)).

In Fig. 5, three modifications of the first embodiment in the views a), b) and c) are shown. In the first modification shown in Fig. 5 a), the bending joint 29g for the pivotable wall portions 29 is formed by a recess on the outside of the corresponding outer wall 10-2, which is located in the height direction Y opposite the transverse wall 10-1. Due to the smaller material thickness of the outer wall 10-2 in the region of the bending joint 29g, the location of the elastic deformation for the pivoting of the wall section 29 can be defined. Such a bending joint can also be referred to as a film hinge.

In Fig. 5 b), two recesses are shown, which are formed in the transverse direction X on both sides of the partition 10-1 on the hollow chambers 10h facing inside of the transverse wall 10-2. These bending joints 29g can be shown as a film hinge.

In Fig. 5 (c), the third modification is shown as a combination of the first and second modifications.

FIG. 6 shows a further modification of the first embodiment in view a). In this case, the latching lug 27r is arranged further (closer) to the outside of the curl body 25 in the transverse direction X than in the embodiments from FIGS. 4 and 5. In Fig. 6 b), a further modification is shown, in which instead of the locking lug 27r a recess 27a, which is complementary to a corresponding nose 28r of the clip device 28, is provided. In Fig. 7, the first embodiment is shown in cross section, are used in the blocks of foam SB in the hollow chambers 1 Oh.

In Fig. 8, in turn, the first embodiment of the insulating web 10 is shown, wherein the hollow chambers 10h are foamed with foam s.

It is obvious, with respect to the embodiments shown in FIGS. 7 and 8, that the possibility of opening and closing the hollow chambers 10h substantially facilitates the insertion of the foam blocks SB or the filling of the foam-foaming material. Of course, only some of the hollow chambers 10h may be filled with foam S, SB, while other hollow chambers are filled with air.

9 shows a second embodiment of the insulating web 10 with three hollow chambers, wherein two of the hollow chambers 10h have a smaller height h than the third, central hollow chamber 10hg.

In the embodiment shown in FIG. 9, the two hollow chambers 10h located outside in the transverse direction X are formed with pivotable wall sections 29, whereas the central hollow chamber 10hg or its wall can not be opened. The hollow chamber 10hg has a substantially greater height hg than the height h of the outer hollow chambers 10h, e.g. 15 mm or more.

10 shows a third embodiment of the insulating web 10. In the third embodiment, the curling body 25 is separated along a parting plane T which is substantially parallel to a plane defined by the longitudinal direction Z and the transverse direction X. At the opposite sides of the parting plane T are clip devices 27, 28 in the form of complementary projections and recesses on both sides (FIG. 10 a) or in the form of recesses on one side and protrusions on the other side (see FIG. 10) b)) or in the form of a recess 27 and a complementary projection 28 (see Fig. 10 c)) are provided.

All embodiments of FIGS. 4 to 10 have in common that the distance b3 of the clip device 27, 28 from the corresponding outer edge 21r, 22r on the outside in transverse direction X, on which the corresponding curl body 25 is located, has a dimension b3 which is smaller than the dimension bl of the depth of the groove 31g, 32g in the transverse direction X. Therefore, it is preferable that the dimension b3 of the distance of the clip device 27, 28 from the corresponding outside is smaller than the dimension b2 of the curl body 25 in the transverse direction X.

In Fig. 1 1 and 12, a fourth embodiment of the Verbundpro fils and the insulating bar 10 is shown. The insulating web 10 of FIGS. 1 1 and 12 is an insulating web, which allows a limited longitudinal displacement of the profile parts 31, 32 in the longitudinal direction Z. This limited longitudinal displacement serves to compensate for the so-called bi-metal effect, which occurs at greatly differing temperatures of the profile parts 31, 32, in particular in the case of large initial stresses in the longitudinal direction Z. The insulating bar 10 has an insulating bar body 20, which extends in the embodiment shown substantially in the longitudinal direction Z and in the transverse direction X and in the height direction Y has a thickness d. Through the Isolierstegkörper through recesses 24 are formed, which are separated from each other by ladder-like webs. On an outer side in the vertical direction Y, a clip recess 27 of the type described with reference to FIGS. 4 to 9 is provided on a curl body 25.

On the opposite side in the transverse direction X of the recesses 24, a clip projection 41 is provided.

The insulating web 10 further comprises a lid 29 which extends in the transverse direction X over the entire width of the recesses 24 and at a free end a clip device 28 which is complementary to the Clipsausnehmung 27 has. At the other free end of the lid 29 in the transverse direction X, a clip recess 42, which is complementary to the clip projection 41, is provided. The lid 29 extends in the longitudinal direction Z substantially parallel to the Isolierstegkörper 20th

As in the embodiments described with reference to FIGS. 4 to 9, the clip devices 27, 28 have a distance b3 from the corresponding outer edge 21 of the insulating strip 10, which is preferably smaller than the dimension b2 of the extension of the curl body in the transverse direction X. In the embodiment of the insulating web shown in FIGS. 11 and 12, the cover 29 can be extruded separately from the insulating web body 20 and subsequently clipped.

The recesses 24 are usually introduced by punching in the Isolierstegkörper 20. If the lid 29 is extruded integrally with the insulating body 20, a significant angle of the bending of the lid 29 is necessary. Due to the separate training this can be avoided, with the formation of the secured in the curled state clip connection 27, 28 nevertheless a very firm connection of the lid can be ensured with the Isolierstegkörper 20.

The formed on the opposite side clip connection 41, 42 may be formed in the arrangement of projection and recess and vice versa. However, the embodiment shown in FIG. 12 a) is preferred.

In Fig. 12 b), an alternative embodiment is shown, in which the non-netted by curling clip connection is formed as a clip connection 43, 44 with a hook-shaped projection 43. The complementary hook 44 formed on the lid 29 is held in engagement by a tensile force acting in the transverse direction X, so that obstruction of the desired longitudinal displaceability of the opposite outer edges 21, 22 can be avoided particularly easily.

There are Isolierstege, which are connected only on one side with a profile part. The invention, i. the rolled-up clip connection can be used there as well.

The Isolierstegkörper all embodiments are made of plastic, preferably made of polyamide or copolyamide, more preferably formed with reinforcing fillings such as glass fibers. Particularly preferred is PA66GF25.
