EP3246505B1 - Composite profile for doors, window or façade elements - Google Patents

Description

The present invention relates in each case to a composite profile for doors, windows or facade elements according to the preambles of claims 1 and 2.

Known composite profiles of this type - see, for example, the generic DE 71 11 558 U - Are often designed as shear-resistant composite. This means that the sub-profiles, which form a frame profile together with an insulating web, can not be displaced relative to one another in the 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. This shear strength is not dug by Dillatationseffekte.

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 it 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 composite is designed so that a relative displacement of its elements 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 shell, as well as between two parts of a composite of these parts insulating web (which preferably consists of plastic). There are also other solutions are known with which unobstructed composite profiles are realized, but in terms of their production, however, are usually quite complex and therefore easier.

Against this background, it is the object of the present invention to provide easily produced composite profiles in which the problems explained above are further minimized by bimetallic effects.

The invention achieves this object by the subject matter of claims 1 and 2. The invention also provides the advantageous method of claim 12.

Created according to claim 1 the following object: A composite profile for doors, windows or facade elements with two outer profiles which are interconnected via an insulating profile arranged between them, wherein between the one ends of the outer profiles, a surface element is used, wherein the insulating profile to each of the outer profiles each having at least two thickened end portions which engage in grooves of the respective outer profiles, wherein the end portions each have mutually facing sides forming the undercuts, and sides facing away from each other, the end faces form. The construction is further characterized in that at least one pressure element - for example in a simple manner an elastomeric spring - is provided, wherein due to the action of the at least one pressure element in each case a torque on one or both of the outer profiles is exercisable, such that two of the end portions of the insulating profile are supported only to their mutually facing undercuts in the respective groove to the two outer profiles. According to this construction, therefore, the insulating profile (one-piece or multi-piece) is arranged between two outer profiles.

There are also constructions in which one of the two outer profiles is integrally formed with the insulating profile, so that the outer profile for this purpose one or more corresponding molded webs to the other outer profile out, which optimize as an insulating profile and the thermal insulation of the outer profile or against a Solution without such a bridge or such webs increase. Claim 2 refers to such a construction. Claim 2 provides: a composite profile for doors, windows or façade elements with two outer profiles, which are connected to each other via an insulating profile integrally formed on one of the two outer profiles - ie one or more insulating webs, wherein between the ends of the outer profiles, a surface element is used, and wherein the insulating profile to one of the outer profiles in each case at least two thickened end portions which engage respectively in corresponding grooves of this outer profile, wherein one of the end portions has sides forming the undercuts, and the other end portion of a side (the other outer profile out ) forms an end face. This construction is characterized in that at least one pressure element is provided, wherein due to the action of the at least one pressure element in each case a torque between the outer profiles is exercisable, such that the one of the end portions of the insulating profile to the corresponding outer profile only at the undercuts of the associated Grooved groove.

It is further provided as a supplement to claim 1 preferably that the other two end portions of the insulating profile are supported with their facing away from each other end faces in the respective other groove, or as a supplement to claim 2, that the other end portion of the insulating profile in the groove with its front side facing this outer profile is supported.

In this way, in each case with structurally simple means on the one hand not shear resistant and on the other hand not shearless but sheared bond between the or the insulating profiles and the outer profiles - claim 1 - or between the one outer profile with or integrally provided thereon insulating profile (s) and the other outer profile - claim 2 - are formed.

At the unsupported surfaces of the insulating profile or the insulating profiles, which lie within the groove, an air gap to the outer profile is preferably formed in each case.

As a result, the assembly of the composite profile is particularly advantageously simplified because only the elements of the composite profile must be plugged together and then the surface element must be mounted on the composite profile. A rolling of webs of the outer profiles of the insulating profile is eliminated.

The term of the outer profile is functional to the arrangement of the at least one (one-piece or multi-piece) insulating profile or more insulating profiles (this also falls under the claims) to relate between the outer profiles. Although the outer profiles can also spatially "completely outside" lie in the composite profile, so that they lie in a manufactured from the composite profile window or in a door that is built into a building opening, once the room inside and once the room outside. However, it can also be provided a composite profile in which, for example, one of the two outer profiles not in the composite profile is completely outside but with this outer profile one or more further layers connect, such as another insulating bar and another metal profile.

Preferably, each one of the two end portions is closer to the surface element than the other of the end portions and due to the action of the pressure element, the torque is exerted on the outer profiles such that in each case lying closer to the surface element end portions of the insulating only at their facing each other Undercuts in the respective groove are supported and that the further away from the surface element remote end portions are each supported with their facing away from each other end faces in the respective groove.

According to a preferred - but not mandatory - design, the pressure element is formed by the fact that between the one ends of the outer profiles and the surface element in each case an elastic element, in particular in each case a seal is arranged, so that the surface element and the seals the outer profiles at these ends press apart ..

In a preferred embodiment of the composite profile, the respective end sections and the respective geometrically corresponding groove are designed and matched to one another such that the respective end sections are fitted with a clearance into the respective geometrically corresponding groove. As a result, the assembly of the composite profile is particularly advantageously simplified.

It is advantageous that the insulating profile is wholly or partially made by extrusion, casting or spraying and that the end portions are mechanically reworked after this production so that their distance corresponds to a predetermined nominal dimension. As a result, the precision of the insulating profile is advantageously increased.

In a further embodiment of the invention, the closer to the surface element end portions of the insulating profile have a different cross-sectional geometry to the farther away from the surface element end portions of the insulating profile. This ensures advantageous that the insulating profile can be mounted only in its correct alignment with the outer profiles.

It is advantageous that the end sections of the insulating profile each have a cross section in the form of a trapezoid, in particular a symmetrical trapezoid. As a result, a geometry with an undercut is produced simply and thus advantageously. In an easily realizable embodiment of the invention, the end portions of the insulating profile are each a cross section in the form of a rectangle.

It can be provided in each case according to advantageous variants that the outer profiles completely or partially made of a metallic material and / or wood and / or plastic and / or the insulating completely or partially made of plastic and / or that the outer profiles on or are formed in several pieces and / or the insulating one or more pieces is formed.

The Fig. 1 shows a door 1, which has a sash 2 and a frame 3. In Fig. 1 the door 1 is shown as hinged door with hinges. Alternatively, the door 1 can also be designed as a sliding door. Alternatively to the in Fig. 1 shown Door 1, the present invention can also be applied to windows or facade elements. If the term door is used below, it can therefore also be replaced by the terms "window" or "facade element".

By a corner joint vertical wing frame bars 5, 6 with an upper horizontal wing frame spar 7 of the profile composite forms an at least U-shaped frame. The frame can also be formed circumferentially closed. The frame 3 of the door 1 is here formed with side parts 8, 9. It has frame frame spars 10, 11. Individual or all of the spars may be formed as composite profiles 4.

In Fig. 2 is one of the composite profiles 4 of a sash 2 in section along with a surface element 42 mounted thereon, such as an insulating or thermal insulation glazing shown.

The composite profile 4 has a first outer profile 12 and a second outer profile 13. In the assembled state on a building is directed from these outer profiles 12, 13 in an application to an external building opening to the room outside and a building inside out.

The outer profiles 12, 13 are formed here as profile shells without hollow chambers. The outer profiles 12, 13 may alternatively also have one or more hollow chambers. The first outer profile 12 and second outer profile 13 are preferably made as extruded aluminum profiles. Alternatively, the preparation is also made of a different material, e.g. Steel and / or possible by another manufacturing method. The outer profiles 12, 13 may consist wholly or partly of a metallic material and / or of wood and / or plastic.

In a Cartesian coordinate system, the Y-axis is parallel to the plane of the surface element 42. The X-axis extends in the image plane of the Fig. 2 perpendicular to it. The Z axis (in Fig. 2 not shown) is perpendicular to the image plane of Fig. 2 ,

The first outer profile 12 is here with respect to a line of symmetry S1, which is parallel to the x-axis with respect to the coordinate system in Fig. 2 runs, designed symmetrically. It has a continuous main web 15. The main web 15 extends here in relation to the coordinate system in Fig. 2 parallel to the y-direction. He has at its two free ends in each case a groove 16, 17. The respective opening of the Grooves 16, 17 points in relation to the coordinate system in Fig. 2 in the positive x direction (towards the surface element 42).

In the groove 16, a sealing profile 18 is inserted. This engages with a T-shaped foot in the groove 16 and is thus in the x and y directions with respect to the coordinate system in Fig. 2 held positively. The sealing profile 18 serves to seal a fold region 19 in the composite profile 4 to the surface element 42. The fold region 19 here also has an insulating profile 43.

The first outer profile 12 has - here between the grooves 16 and 17 - at least two (here further) grooves 20, 21. These are formed here in a preferred embodiment symmetrically to the line of symmetry S1 on the main web 15.

The grooves 20, 21 are each formed by two angle webs 22a, b and 23a, b, each in the positive x-direction with respect to the coordinate system in Fig. 2 or at a right angle to the main web 15, are formed integrally with the main web 15. Between the ends of the angle webs 22a, b; 23a, b, a gap is formed in each case. The free ends of the angle webs 22a, b; 23a, b are directed towards each other.

The groove 20, here with a variable with respect to the depth of the groove groove width 20, here has a cross section in the form of an isosceles, symmetrical trapezoid, wherein the groove width in the positive x-direction with respect to the coordinate system in Fig. 2 increased. The groove 21, with a with respect to the depth of the groove 20 constant groove width, here has a cross section in the form of a rectangle. The groove opening of both grooves 20, 21 has in each case with respect to the coordinate system in Fig. 2 in positive x-direction. Both grooves 20, 21 each have an undercut in the region of the respective slot opening.

The second outer profile 13 also has a main web 24 and a glass retaining strip 27 attached thereto. The main web 24 extends here in relation to the coordinate system in Fig. 2 parallel to the y-direction and has at its two free ends in each case a groove 25, 26 from. The opening of the groove 25 is in the negative x-direction with respect to the coordinate system in Fig. 2 aligned. The groove 25 is arranged in the composite profile 4 with respect to a symmetry line S2 symmetrical to the groove 17 of the first outer profile 12. The opening of the groove 26 is in the positive y-direction with respect to the coordinate system in Fig. 2 aligned.

In the groove 26, the glass retaining strip 27 is inserted, which engages with a T-shaped foot in the groove 26.

On the glass retaining strip 27, a first elastic sealing profile 28 is arranged, which is clamped between this and the glass retaining strip 27. The sealing profile 28 also serves to seal the folding area 19 on the composite profile 4 to the surface element 42.

The glass retaining strip 27 is held and fixed with a retaining clip 44 in the manner of a clip on the first outer profile 12.

The second outer profile 13 has (as the first outer profile 12) at least two (further) grooves 29, 30, which are arranged here symmetrically to the line of symmetry S1 on the main web 24.

The grooves 29, 30 are each formed by two angle webs 22 c, d and 23 a, b, each in the negative x-direction with respect to the coordinate system in Fig. 2 or at a right angle to the main web 24, are formed integrally with the main web 24.

The groove 29, here with a variable with respect to the depth of the groove 29 groove width, here has a cross-section in the form of a symmetrical trapezoid, wherein the groove width in the positive x-direction with respect to the coordinate system in Fig. 2 reduced. The groove 30, here with a with respect to the depth of the groove 30 constant groove width, here has a cross section in the form of a rectangle. The groove opening of both grooves 29, 30 respectively points in the direction of negative x-coordinates with respect to the coordinate system in FIG Fig. 2 , Both grooves 29, 30 thus each have an undercut in the region of the respective slot opening.

The grooves 29, 30 are arranged here in the composite profile 4 with respect to a line of symmetry S2 symmetrical to the grooves 20 and 21 of the first outer profile 12, which is advantageous because such a statically very advantageous embodiment is formed. Alternatively, however, the grooves 29, 30 of the second outer profile 13 may also be arranged asymmetrically with respect to the grooves 20, 21 of the first outer profile 12.

The first outer profile 12 is connected to the second outer profile 13 via an insulating profile 14. The insulating profile 14 is made of a heat transfer reducing material, preferably made of a plastic material, so that the insulating profile 14 in the assembled composite profile 4 a substantial thermal separation between the metal profiles 12, 13 is achieved.

The insulating profile 14 (see also Fig. 3a . Fig. 3b . Fig. 4 . Fig. 9 ) is designed here as a one-piece profile. However, the insulating profile 14 may alternatively (not shown here) be formed in several pieces. And for example, consist of two individual webs, which are perpendicular to the surface element 42 spaced from each other or via a connection z-.B. mechanical type as a locking connection is connected to mutually facing webs together and form a mounting unit.

Here, in a preferred embodiment, it has a symmetrical H-shaped basic cross-section to the symmetry line S2. Alternatively, the insulating profile 14 may also have an asymmetrical cross section or be designed in several parts. The insulating profile 14 has a central region 31. The central region 31 of the insulating profile 14 here has a plurality of hollow chambers 37, 38. Alternatively, the central region 31 may have only one or no hollow chamber 37, 38. Through the hollow chambers 37, 38, the thermal insulation properties of the insulating profile 14 are advantageously improved. The central region 31 is here an integral part of the insulating profile 14, which is advantageous but not mandatory. The central region 31 could also consist of a different material than the remaining insulating profile 14.

The insulating profile 14 also has webs 32a, 32b and 33a, 33b. The webs 32a and 32b extend outwardly from the central area in an opposite direction (in mounted position to the outer profiles 12, 13). The webs 33a and 33b extend outwardly from the central area in the opposite direction (in mounted position to the outer profiles 12, 13). The webs 32a and 33a on the one hand and 32b and 33b are parallel to one another here in a further preferred embodiment. The webs 32a and 32b on the one hand and 33a and 33b are also aligned here in a further preferred embodiment. This contributes to a good statics in each case with beneficial, but is not mandatory. In the simplest embodiment, the central region 31 can also form only one connection point in the webs 32a, b and / or 33a, 33b.

More specifically, the ridge 32a extends from the central region 31 in the negative x-direction with respect to the coordinate system in FIG Fig. 2 . 3a . 3b . 4 . 9 while the ridge 32b, starting from the central region of the insulating profile 14 with respect to the coordinate system in Fig. 2 extends in the positive x direction. Analogous to the webs 32a, 32b are the webs 33a, 33b at the central region 31 of the insulating profile 14, but with respect to the coordinate system in Fig. 2 spaced from the webs 32a, 32b in the negative Y direction. The webs 32a, 32b 33a, 33b thus each form the free ends of the rotated by 90 °, H-shaped cross section of the insulating profile 14. The webs 32a and 33a and 32b and 33b so here each form a partial symmetry on the insulating profile 14, the line of symmetry marked S1.

The central region 31 of the insulating web 14 has two further webs 34a, 34b. The webs 34a, 34b rise in the positive y-direction with respect to the coordinate system in Fig. 2 . Fig. 3a . Fig. 3b . Fig. 4 via the central region 31 and are arranged symmetrically to the symmetry line S2. The webs 34a, 34b protrude in the composite profile 4 in the folding area 19 and fix in the assembled state of the surface element 42 -here as glazing executed- the insulating profile 43rd

The webs 32a, 32b, 33a, 33b each have thickened end portions 35a, 35b, 36a, 36b. The cross-sectional geometry of the end portions 35a, 35b and 36a, 36b can be designed arbitrarily. Preferably, the respective end portions 35a, 35b, 36a, 36b have a flat surface at their respective free end.

The end portions 35a and 35b show in the embodiments Fig. 3a . Fig. 3b . Fig. 4 each have a cross section in the form of a symmetrical trapezoid. Alternatively, the cross section may also be designed in the form of an asymmetric trapezoid. Other geometries are also conceivable. It is in the embodiment of the insulating 14 after Fig. 3a . Fig. 3b . Fig. 4 the design of the trapezoid chosen so that a width B of the trapezoid in each case increases in the direction of the central region 31 of the insulating 14, so that in each case in a boundary region to the respective web 32a, 32b, an undercut 39a, 39b and 40a, 40b is formed (see also Fig. 5 ). The width B of the trapezoid designates the extent of the trapezoid in the y-direction with respect to the coordinate system.

The end portions 36a and 36b here each have a cross section in the form of a trapezoid in the special geometry of a symmetrical trapezoid, here a rectangle. Other geometries are also conceivable, such as non-symmetrical trapezoids or completely different cross sections. It is in the embodiment of the insulating 14 after Fig. 3a . Fig. 3b . Fig. 4 the design chosen so that the rectangle corresponds to a square. Accordingly, the free end of the respective end region 36a, 36b has an end face or end face 41a or 41b. See also Fig. 6 ,

In this case, each of the end sections 35a, 35b or 36a, 36b preferably engages in the respective geometrically corresponding groove 20, 29 or 21, 30, which is formed in each case by one of the metal profiles 12, 13. Dimensionally, the respective end portions 35a, 35b and 36a, 36b and the respective geometrically corresponding groove 20, 29 and 21, 30 designed and matched to each other, that the respective end portions 35a, 35b and 36a, 36b with a game in the each geometrically corresponding groove 20, 29 and 21, 30 are fitted. This facilitates the assembly of the composite profile 4 in an advantageous manner.

Due to the different cross-sectional geometry of the end portions 35a, 35b and 36a, 36b and the respective geometrically corresponding grooves 20, 29 and 21, 30 is advantageously ensured that the insulating profile 14 only in its correct alignment with the outer profiles 12, 13 can be mounted , This is advantageous but not mandatory.

The webs 32a, 32b and 33a, 33b, including their end portions 35a, 35b and 36a, 36b, respectively here have the same length or the same longitudinal extent in each case in the positive or negative x-direction with respect to the coordinate system in the Fig. 2 . 3 . 4 , measured in each case from the symmetry line S2-. This results in each case an imaginary plane, which is spanned by the respective free ends of the end portions 35a, 36a and by the respective end faces 41a, 41b of the end portions 36a, 36b and thus in each case parallel to the yz plane of the coordinate system in Fig. 4 is stretched.

As part of a mechanical post-processing of the insulating profile 14 provided by extrusion to increase the dimensional precision of the insulating profile 14, it is provided here that at the end portions 35a, 35b (with here preferably but exemplary) trapezoidal cross section at least the respective inner surfaces of the undercuts 39a, 39b or 40a, 40b and in a calibration tool (eg, a cutting or milling device with two precisely spaced knives / milling) are brought to a more accurate level, as can be achieved in an extrusion to provide the insulating profile (see Fig. 4 and Fig. 5 ).

The inner - facing each other - surfaces of the undercuts 39 a, b and 40 a, b of the end portions 35 a, b, which in the mounted position of Fig. 2 closer to the surface element 42 are, thus, by the post-processing after the extrusion with respect to a predetermined desired distance more accurately spaced apart than after the extrusion. This is advantageous and essential in this embodiment. They are also advantageously aligned parallel to each other here. This is also advantageous. The remaining geometry of these end portions 35a, b is less important. It can be a trapezoid but also, for example, another cross-sectional geometry, such as a semicircle.

In the context of the mechanical reworking of the insulating profile 14 to increase the dimensional precision of the insulating profile 14 is further provided that at the end portions 36a, 36b (here by way of example but not necessarily rectangular cross-section) at least the respective remote from each other, outer end faces 41a, 41b after the Extrusion can also be reworked to bring the distance between these end faces 41a, 41b to a more accurate distance measure, than this is achieved in extrusion production of the insulating profile 14 (see Fig. 4 and Fig. 6 ).

The outer - facing away from each other - end faces 41a, b of the end portions 36a, b, which in the mounted position of the Fig. 2 are further away from the surface element 42, are thus aligned by the post-processing after extrusion preferably parallel to each other and have a very accurate distance measure. This is advantageous and essential in this embodiment. The remaining geometry of these end portions 36a, b is less important. It can be a trapezoid, here a rectangle formed, but for example, another cross-sectional geometry, such as a semicircle.

In Fig. 3a is the composite profile 4 with the two outer profiles 12, 13 and the insulating profile 14 after assembly of the outer profiles 12, 13 shown with the insulating profile 14.

The trapezoidal cross-section end portions 35a, 35b of the insulating profile 14 are after the assembly of the composite profile 4 with a point or line contact to the respective geometrically corresponding groove 20 and 29 of the respective outer profile 12, 13 after assembly of the composite profile 4.

The end portions 36a, 36b with a rectangular cross-section of the insulating profile 14 are after the assembly of the composite profile 4 with a point or line contact on the geometrically corresponding grooves 21 and 30 of the respective outer profile 12, 13.

The two outer profiles 12, 13 also depend on the assembly of the composite profile 4 due to the prevailing lever and force relationships and the design of the respective fit between the respective end portion 35a, 35b and 36a, 36b and the respective geometrically corresponding groove 20, 21 and 29, 30 with a game initially each at an angle α and β with respect to the symmetry line S2. Thus, the composite profile 4 initially has a kind of A-shaped configuration with respect to its cross-section, wherein the opening of the "A" with respect to the coordinate system in FIG Fig. 4 towards negative y-values (the opening is away from the surface element 42).

In Fig. 3b is the composite profile 4 off Fig. 2 under load of the surface element 42 mounted in the folding area 19 (not shown here, see FIG Fig. 2 ). Among other things, since the sealing profiles 18, 28 (see Fig. 2 ) develop their sealing effect by an elastic deformation of the respective sealing profile 18, 28, acts in each case a reaction force F1, F2, each resulting from the deformation of the sealing profiles 18, 28, on the respective outer profile 12, 13 of the composite profile. 4

The reaction forces F1, F2 generate, in cooperation with the insulating profile 14, in each case a torque M1, M2, which acts in each case on the outer profiles 12, 13. The two torques M1, M2 act opposite to each other in terms of their sense of rotation.

Due to the forces F1, F2 or torques M1, M2 respectively acting on the two outer profiles 12, 13, the following situation arises with respect to the end sections 35a, 35b or 36a, 36b of the insulating profile 14 (see also FIG Fig. 5 and Fig. 6 ):
The reworked surfaces of the undercuts 39a, 39b and 40a, 40b of the end portions 35a, 35b with a trapezoidal cross-section of the insulating profile 14, abut the geometrically corresponding undercut of the respective groove 20 and 29 of the respective outer profile 12, 13, so that between the respective groove bottom of the grooves 20, 29 and the respective end portion 35a, 35b with trapezoidal cross-section results in a game SP1.

The outer post-processed end faces 41a, 41b of the end portions 36a, 36b of rectangular cross-section abut against the respective groove bottoms of the geometrically corresponding grooves 21 and 30, respectively, so as to interplay between a web-facing side and an undercut of the respective geometrically-corresponding groove 20, 29 SP2 results.

The composite profile 4 accordingly has, after the assembly of the surface element 42, substantially parallel outer profiles 12, 13. Under the load of the glazing, the end portions 35a and 35b become trapezoidal Cross section or the corresponding webs 32a and 32b on train and the end portions 36a and 36b with rectangular cross section and the respective webs 33a and 33b loaded on pressure.

By the remaining respective game SP1 or SP2 (see Fig. 5 and Fig. 6 ) so easily and thus advantageously a composite profile 4 is provided which allows a displacement of the outer profiles 12, 13 relative to the insulating profile 14 due to dilation.

The composite profile 4 thus has a shear-reduced, in particular shear-soft or unobstructed connection between the outer profiles 12, 13 and the insulating profile 14.

This results in an advantageous composite profile 4, which can compensate for temperature-induced deformations by a shear-soft or unobstructed connection of one of the outer profiles 12, 13 and the insulating section 14.

In order to avoid repetitions, only deviations or additions to the respective end sections 35a, 35b or 36a, 36b will follow Fig. 4 . Fig. 5 such as Fig. 6 described.

An introduction of force into the respective end section 36a, 36b after assembly of the surface element 42 takes place here analogously to the end sections 36a, 36b Fig. 6 over the end faces 41a, 41b of the rectangle. In the mounted state of the insulating profile 14 with the two outer profiles 12, 13, the clearance SP2 results in each case between an undercut of the respective geometrically corresponding groove 21 and the respective end face 41a, 41b of the rectangle (see Fig. 8 ).

In Fig. 9 is a variant of the composite profile Fig. 2 respectively. Fig. 3b shown. In order to avoid repetitions, only deviations or additions to the composite profile 4 will follow in the following Fig. 2 respectively. Fig. 3b described.

The composite profile 4 after Fig. 9 Contrary to the composite profile 4 at the webs 32a, 32b, which are positioned at the central region 31 of the insulating profile 14 with magnitude larger y-values with respect to the coordinate system, end portion 35a, 35b with trapezoidal cross-section, wherein the here symmetrical trapezoid as in Fig. 7 illustrated is designed so that the width B of the trapezoid in the direction of the central region 31 of the insulating 14 is reduced, so also in each case an undercut 39a, 39b or 40a, 40b is formed, which is formed in each case by the flanks of the trapezoid, as in Fig. 7 is shown.

The mechanical reworking takes place at the end section 35a or 35b Fig. 7 in each case at an end face of the trapezoid facing the respective free end of the respective end region 35a, 35b. An introduction of force into the respective end section 35a, 35b after assembly of the surface element 42 takes place here analogously to the end sections 36a, 36b Fig. 6 over a machined end face of the trapezoid. Alternatively, the cross section of the end portions 35a, 35b after Fig. 9 (respectively. Fig. 7 ) also be designed in the form of an asymmetric trapezoid.

The grooves 20, 29 in the outer profiles 12, 13 are correspondingly designed geometrically corresponding to the end portions 35a, 35b. In the assembled state of the insulating 14 with the two outer profiles 12, 13 results in the game SP 1 each parallel to the flanks of the trapezoid (see also Fig. 7 ).

To Fig. 10 is between one of the outer profiles - here in the drawing left outer profile 12 - and the insulating profile 14 as the pressure element at least one elastomeric spring 46a, in particular with a hardness of 30 to 98 Shore arranged. This elastomer spring 46 is located here next to the web 32a. It lies directly between the web 22a and a shoulder of the insulating profile 14 between these two elements, so that they push apart these two elements with their given in this position spring force. Otherwise, the insulating profile engages again with end portions 35a and 36a in grooves 20, 21 of this outer profile 12 (in Fig. 10 left).

To Fig. 10 is alternatively or optionally further between the other of the outer profiles - here in the drawing right outer profile 12 - and the insulating profile 14 as the pressure element at least one elastomeric spring 46b, in particular with a hardness of 30 to 98 Shore arranged.

Due to the force acting on the two outer profiles 12, 13 here respectively by the elastomer spring 46 respectively forces or torques M1, M2 results in terms of the end portions 35a, 35b and 36a, 36b of the insulating 14 a to FIGS. 5 and 6 comparable or basically the same situation (see also Fig. 5 and Fig. 6 ). Also, this composite profile 4 thus has a thrust-reduced, in particular shear-soft or unobstructed connection between the outer profiles 12, 13 and the insulating section 14.

To Fig. 11 this is one of the external profiles 12, 13 - the in Fig. 1 Right outer profile 13 - integrally formed with the insulating profile 14, the anticipated here interface between the two elements "insulating" and "outer profile" deleted by integral web connections. This outer profile 13 adjacent to the insulating profile 14 forming webs is preferably made of plastic and the other of the outer profiles 12, preferably made of metal. On the other hand Isolierprofil 12 towards the construction here, however, similar to those of Fig. 10 ,

In this case, between the one outer profile 13 with the insulating section 14 and the other outer profile 12, in turn, as the pressure element at least one elastomeric spring 46a, in particular with a hardness of 30 to 98 Shore arranged.

Due to the forces or torques M1, M2 acting (primarily) on the two outer profiles 12, 13 (primarily) by the at least one elastomer spring 46a, the following situation arises with respect to the end sections 35a and 36a of the insulating profile 14 (see also FIG Fig. 5 and Fig. 6 ).

The reworked surfaces of the undercuts 39a, 39b of the trapezoidal-shaped end section 35a of the insulating profile 14 abut against the geometrically corresponding undercut of the groove 20 of the outer profile 12 so that a clearance exists between the respective groove bottom of the groove 20 and the trapezoidal-shaped end section 35a (like SP1 in FIGS. 5 and 6 ).

The outer post-processed end faces 41a of the end section 36a with a rectangular cross-section, however, directly against the groove bottom of the geometrically corresponding groove 21, so that in each case between a side facing the insulating 14 and an undercut of the groove 21 a game (comparable SP2 in FIGS. 5 and 6 ).

The composite profile 4 accordingly has, after the assembly of the surface element 42, substantially parallel outer profiles 12, 13. Under the load of the glazing, the trapezoidal section end portion 35a is subjected to tension and the rectangular section end portion 36a is pressure-loaded.

Similar to the remaining game FIGS. 5 and 6 Thus, a composite profile 4 is created so easily and thus that allows a displacement of the outer profiles 12, 13 relative to the insulating profile 14 due to dilation.

Also, this composite profile 4 thus has a thrust-reduced, in particular shear-soft or unobstructed connection between the outer profiles 12, 13 and the insulating section 14.
