Description

The present invention relates to a plastic profile for window, door and facade elements.

Window systems usually consist of a sash profile and a frame profile, the glazed wing and the frame with the building envelope (masonry) is connected. These profiles consist e.g. made of wood, steel, aluminum, plastic or combinations of these materials. The variety of competing materials is partly traditional, but for another, the factors thermal properties, wind-tightness, maintenance costs, aesthetic impact and price are crucial for the choice of material.

There are in the art (eg DE 33 19 144A1 ) extruded hollow profiles made of plastic for windows and doors, in which the hollow profile part has a plurality along the hollow profile part extending hollow chambers. Such hollow profile parts are usually formed of rigid PVC. One or more of the inner chambers may be filled with foamed plastic (see also the EP 1 154 115 B1 ). The corner joint of window frames of such hollow profile parts is produced by welding or by the use of corner connectors which are glued.

The window manufacturer Schüco, Bielefeld, Germany offers window systems (such as, for example, the Corona CT 70 Plus) with foam-free hollow plastic profiles with several hollow chambers and conventional steel reinforcement, in which steel reinforcement profiles are arranged in hollow chambers by insertion. The steel reinforcement profiles are also used for anchoring fittings. With these window systems it is possible to attach aluminum decorative outer shells.

From the DE 201 05 876 U1 , of the DE 32 42 909 A1 and the WO 97/22779 A1 Profiled parts made of plastic foam for window elements are known, in different ways insulating shells (DE 201 pos 876 U1) or profile parts made of metal ( DE 32 42 909 A1 ) or also made of wood or plastic ( WO 97/22779 A1 ) connected to the core of plastic foam are. In the from the DE 201 05 876 U1 known PU foam core separate core profiles are provided in the PU profile.

From the EP 1 705 334 A2 is a plastic profile part for window and door elements known in which metal profile parts are glued or rolled to the two outer sides of the plastic profile part, which form the inside and outside of the window and door element.

Furthermore, aluminum windows, doors and facade elements, which consist of aluminum-plastic composite profiles of weather-side and room-side aluminum profiles, which are non-positively / positively connected with plastic profiles known. The profiles are assembled in the manufacture of the components into frames, wherein the corners are mechanically connected by inserted corner connectors. In addition, composite windows, doors and façade elements, which consist of composite profiles of weather-side and room-side profiles with freely selectable materials, which are non-positively / positively connected to plastic profiles, known ( EP 1 555 376 A1 ). The DE 200 16 611 U1 discloses a reinforced plastic profile for windows, etc., in which a U-shaped groove for receiving fittings, etc., in which a reinforcing profile is attached, is provided.

From the WO 84/03326 A1 is a composite profile with 2 parallel metal profiles, which are connected by means of an insulating plastic profile by rolling, known in which the furthest in the direction of the plastic profile projecting parts of the metal profiles are the rolling hammers.

From the EP 0 764 756 A1 is another composite profile known.

The EP 1 353 034 A2 discloses a plastic profile with two outer arms between which lie two feet of an aluminum profile, which is positively connected to the arms.

It is an object of the invention to provide an improved plastic profile for window, door and facade elements and a reinforced plastic profile with such a plastic profile for window, door and facade elements.

This object is achieved by a plastic profile according to claim 1 or a reinforced plastic profile according to claim 8 or a window, door or facade element according to claim 13.

Further developments of the invention are specified in the subclaims.

B. a multi-piece plastic profile body (115, 116, 117) _; the at least one outer profile body (115a, 116a, 117a) and at least one inner web portion (115b, 116b, 117b), and / or the plastic profile body (111, 112, 113, 114, 115, 116, 117) may be at least partially foamed ,

An armored plastic profile according to any one of claims 8 to 12 may be adapted to optionally decor panels (61, 62, 61, 64) are attachable to the outer sides in the transverse direction (x), and / or that a fitting element in a functional area (131 , 133) is received in the outer geometry of the plastic profile body.

The invention enables a profile system for windows, doors and facades are used in the hollow sections made of plastic with rolled reinforcements, which are installed positionally accurate and longitudinally fixed, which allow a relatively large proportion of the insulating zone to the entire depth.

An embodiment of a profile system according to the invention for windows, doors and facades consists of plastic profiles, preferably made of plastic hollow sections, and outer Armierungsprofilen, preferably made of aluminum, which have a precisely positioned for outer surface receiving chamber for corner joints and longitudinally connected by a curling with the plastic hollow profile.

The plastic profile forms an insulating zone and the proportion of the insulating zone in the overall depth from the room side to the weather side is preferably 80% or more, more preferably 90% or more, still more preferably 95% or more.

The profiles can be connected by analogy to aluminum windows by corner connectors to components such as window, door and facade elements.

For the production of plastic profiles of, for example: rigid PVC, PA, PET, PBT, PA / PPE, ASA (reinforced or unreinforced) or others, a manufacturing method is used which calibrates both the outer contour and the inner contour positionally accurate.

Accurate position calibration ensures accuracy that positions inserted and fixed armor with the required low tolerance to the outside contour.

The invention provides several advantages for the design of the properties of window, door and facade elements in which the reinforced plastic profile is used.

a) Thermal properties

The thermal quality can be designed by the increased proportion of hollow plastic profiles in the depth and the design, size and distribution of the internal cavities, as well as by their foaming.

b) Mechanical properties

The mechanical properties such as torsional stiffness, etc., can be shaped by the depth (i.e., the distance of the weather side to the room side armor) and the design, size, and cross sectional area of the armor.

c) cross section

In the cross-section of the profiles undercuts and arbitrarily complex geometries for receiving fitting and locking elements, seals and other by the use of hollow plastic profiles are possible.

d) surface and color design

The surface and color scheme can be varied by selecting and coloring the plastic and / or by using decorative elements for different design of weather side and room side versatile.

1. a) in der Schließebene Dichtungsaufnahme, Dichtungsanschlag, Beschlagsaufname,
2. b) zur Verglasung Klotzflächen, Funktionsnuten für die Glasleiste, Glasdichtungsaufnahme und Entwässerung,
3. c) zur Gebäudehülle (Mauerwerk) Nuten, Fensterbankanschlag, Aufnahme für Abdichtungsfolien usw., und
4. d) zur Außen- und Raumseite glatte farbige und witterungsbeständige Oberflächen des Hohlprofils und/oder Rastnasen zum Befestigen von Dekorprofilen aus Kunststoff, Holz, Aluminium oder Edelstahl (stranggepresst oder gerollt)

The outer contour of the hollow profile is determined by the features to be guaranteed such as

1. a) in the closing plane, seal seat, sealing stop, fitting,
2. b) for glazing, block surfaces, grooves for the glazing bead, glass seal support and drainage,
3. c) to the building envelope (masonry) grooves, windowsill stop, recording for sealing foils, etc., and
4. d) to the outside and room side smooth colored and weather-resistant surfaces of the hollow profile and / or locking lugs for attaching decorative profiles made of plastic, wood, aluminum or stainless steel (extruded or rolled)

The reinforcement is preferably made of extruded aluminum hollow profiles with an inner contour for receiving corner connectors (as is usual in aluminum windows) and an outer contour with positioning surfaces for precise definition of the position in the plastic hollow profile.

The reinforcements can have additional functions, as they are necessary for the screwing of T-joints or fittings.

The plastic hollow profiles are preferably made of reinforced materials, e.g. PA 66 GF, and have functional elements on the outer contour, e.g. for receiving fitting and locking elements, seals, glass retaining strips, recording decorative covers and the like.

The hollow plastic profiles for windows, doors and facades receive a sufficient static load capacity through the reinforcing profiles, which are longitudinally connected and preferably formed of aluminum. The reinforcing profiles preferably have an area which is suitable for receiving corner joints. Preferably functional areas for receiving fitting and locking elements, seals, glass retaining strips can be integrated into the plastic hollow profile. Preferably, the reinforcing profiles can be covered with decorative panels. The plastic hollow profiles meet application-related mechanical requirements by choosing a suitable plastic, for example, PA 66 GF.

The reinforcing profiles may e.g. be prepared by knurling suitable for the longitudinally fixed connection with the plastic profiles.

Fig. 6

an enlarged view of a part of the first embodiment Fig. 1 ,

Based Fig. 1 and Fig. 6 a first embodiment of the invention will be described. In Fig. 1 are profile parts, as they are part of a frame profile and a sash profile, shown in cross-section (xy plane) perpendicular to the longitudinal direction (z) of the corresponding profile parts.

On the right in Fig. 1 a plastic hollow profile 111 is shown in cross-section perpendicular to its longitudinal direction, which forms part of a window sash. In a manner known per se, a double glass pane 200 can be held by means of sealing / fastening elements 201, which can also be formed in another form, and a glass strip 202 on / in the frame of the window sash. In the Fig. 1 top side is the room side and the in Fig. 1 The bottom side is the weather side of the profile parts.

The plastic hollow profile 111, which forms part of a sash, extends in a transverse direction x, which is perpendicular to the longitudinal direction z and perpendicular to a width direction y, which is again perpendicular to the longitudinal direction z, from the weather side (bottom in FIG Fig. 1 ) to the room side (top in Fig. 1 ). On an outside (weather side), an aluminum hollow profile 21 is attached to the plastic hollow profile 111 in a manner described later. On the opposite side in the transverse direction x, ie the space side (top in Fig. 1 ), an aluminum hollow profile 22 is fastened in a similar manner. Between the two outer sides is a hollow chamber, which is foamed in the first embodiment with a foam 50 low density. The plastic hollow profile has in cross-section (xy) perpendicular to its longitudinal direction z a complex geometry with undercuts, projections and the like for receiving fitting and locking elements (not shown), Gaskets 201, 211, 212, reinforcing strips 23 and other elements such as the window molding 202 and / or for attaching decorative elements 61 on.

The fastening of the aluminum hollow profiles 21, 22 will now be with reference to Fig. 6 described by way of example for the aluminum hollow profile 21. As in Fig. 6 can be clearly seen, the plastic hollow profile 111 on the corresponding outer side (here weather side) curl projections as the curl projections 121a projecting from the plastic hollow section 111 in the transverse direction x and so the furthest projecting on this outside portions / parts of the plastic hollow section 111 ,

The aluminum hollow profile 21 extends in the longitudinal direction z and has a hollow chamber 21 a, which is surrounded by a rectangular in cross-section outer wall. Of course, other cross sections for the hollow chamber are possible, but a rectangular cross-sectional shape whose longer side is in the width direction y, is preferred. From the rectangular wall extending in the width direction y projections 21b, whose ends are formed as a hammer (roll-in hammer) 21ba for rolling and with another part of the aluminum hollow profile (here the wall of the hollow chamber) form the groove.

The curl projections 121a of the plastic hollow profile 111 are, as in FIG Fig. 6 is well recognized, formed in a corresponding kinked shape such that the tips as heads (curling heads) 121aa of Einrollvorsprünge 121a with the hammers 21ba of the projections 21b of the aluminum hollow profile 21 after the rolling process for longitudinally holding the aluminum profile cooperate and that the aluminum hollow profile 21 with the plastic hollow profile 111 comes into contact only on the heads 121aa. The plastic hollow profile is otherwise received in a receptacle 121 such that it does not come into contact with the plastic hollow profile 111 surrounded by an air cushion. That is, the length of the protrusions 121a, that is, the protruding amount against the wall 121b that defines the receptacle 121 is sized so that the depth of the aluminum hollow profile 21 measured in the transverse direction x is smaller relative to the protrusions 21b.

The above statements on the formation of the roll-in projections and the aluminum hollow profiles apply to all embodiments.

Basically, the wall 121b for the inside boundary of the receptacle 121 is not necessary, as later with reference to the Fig. 4 and 5 is explained. In the present first embodiment, however, an inside boundary of the receptacle 121 is provided and preferred.

As is clear from the Fig. 1 Similarly, the aluminum hollow profile 22 is similarly fixed to Einrollvorsprüngen 122 a, 122 c on the opposite outer side (space side) of the plastic hollow profile 111 longitudinally by rolling. In this case, unlike in the case of the weather side, the curl projections 122a, 122c are not of the same length. Nevertheless, on the room side as well, the curl projections 122a and 122c are the most transverse portions x on the room side projecting portions / parts of the plastic hollow profile 111.

The aluminum hollow profile 22 has a hollow chamber 22a surrounded by a wall of rectangular cross-section and projections 22b, 22c extending in the width direction y. These are, unlike the aluminum hollow section 21, adapted to the realization of other functions. Thus, in addition to the hammer 22ba for curling, the projection 22b also has a further projection 22bb, which serves for clicking on a decorative element 62. The protrusion 22c includes the hammer 22ca for curling and an extension 22cb to which a receptacle 22cc for the seal 211 and a protrusion 22cd for clicking the decor 62 are provided.

Basically, the aluminum hollow sections 21, 22 serve as reinforcing elements, which are longitudinally fixed to the plastic hollow profile 111 by rolling. As a result, the mechanical properties of a reinforced plastic hollow profile, which consists of the hollow plastic profile 111 and the aluminum hollow sections 21, 22, achieved.

By forming a plastic hollow profile 111 so that the curl projections 121a, 122a, 122c in the transverse direction x are the most protruding portions / parts of the plastic hollow profile 111, and the arrangement of the essential part of the aluminum hollow profiles substantially between the curl projections, or more generally within the Plastic hollow sections, a maximum extent of plastic is formed Insulating zone in relation to the total depth in the transverse direction x reached. Unlike known composite profiles, the extension of the cross-section of the aluminum hollow profile in the transverse direction x is not added to the size of the insulating zone, but in the present case the extension of the cross section of the aluminum hollow profile in the transverse direction x is largely within the extent of the insulating zone in the transverse direction x, without reducing the extent of the insulating zone x.

Thus, a proportion of the insulating zone in the overall depth in the transverse direction x of at least 80%, in the present case (without decorative panels) even 92% in the case of the aluminum hollow sections 21, 22 reinforced plastic hollow section 111 is achieved. With a corresponding change of the projection 22c and extension of the curl projection 122c to the length of the Einrollvorsprungs 122a and 96% are possible.

The decorative elements 61, 62 may e.g. be designed as aluminum shells, which are clipped to the profile. There are also other materials such as stainless steel, wood, plastic, etc. for the decorative elements 61, 62 possible. It should be noted that the use of a highly thermally conductive material for the decorative trims, especially if they extend further in the transverse direction x to the inside of the plastic hollow profile 111 like the decorative panel 61 (unlike the decorative panel 62), brings about a deterioration of the insulating properties, but which is much lower than the improvement achieved by the described connection of the aluminum hollow sections with the hollow plastic profile. In addition, these decorative elements can be made very thin, so that further optimizations are possible here.

The plastic hollow profile 111 has, as already described above, a complex geometry. For example, the plastic hollow profile 111 has an undercut recess 131, which is adapted for receiving fitting and locking elements. In the following description is on the Fig. 2 Reference is made, the plastic hollow profile 111 is identical to the plastic hollow profile 111 of the first embodiment. The recess 131 extends in the longitudinal direction z. In the width direction y, the outer wall of the plastic hollow profile 111 forms the rear wall of the undercut recess 131. In the transverse direction x, the recess 131 on the room side becomes a hook-shaped projection 131a limited. In the transverse direction x on the weather side, the outer wall of the plastic trough profile 111 extends at right angles from the part forming the rear wall and has a protrusion 131b projecting toward the room side, so that the undercut recess 131 is bounded overall.

On the inside of the rear wall of the undercut recess 131, a further undercut recess 132 is formed. The undercut recess 132 is bounded by the same part of the outer wall of the plastic hollow profile 111 as a rear wall in the width direction y. In the transverse direction x on the weather side, the recess 132 is bounded by a hook-shaped projection 132b and delimited on the room side by the outer wall of the plastic hollow profile 111 and a protrusion 132a projecting at right angles from this outer wall in the direction of the weather side.

The recess 132 forms a receptacle for a reinforcing element (reinforcing strip) 23, whose function is the secure fastening of the fitting and locking elements, which are received in the undercut recess 131 on the outside. The reinforcing element 23 is held in position by the foam 50 or otherwise (e.g., screws).

The plastic hollow profile 111 of the first embodiment has a continuous from the room side to the weather side hollow chamber. This hollow chamber is foamed with foam 50 for reasons of thermal insulation and strength increase. Depending on the requirement, the plastic hollow profile may have one or more hollow chambers which, depending on the requirements, are completely or partially filled with foam or not at all. The density of the foam used can be varied depending on the requirements.

On the left in Fig. 1 a plastic hollow profile 112 is shown, which is part of a frame profile. In the same way as in the plastic hollow profile 111 aluminum hollow sections 24, 25 via roll-up projections 124a, 125a by rolling longitudinally fixed to the plastic hollow profile 112 is connected. Also, the plastic hollow profile 112 has a continuous from the weather side to the room side hollow chamber, which is foamed with a foam 50. In a comparable way, the hollow aluminum profiles 24, 25 have a hollow chamber 24a, 25a, which are surrounded by rectangular in cross-section outer walls, on. Even with the hollow profile 112, the curl projections 124a form a receptacle 124 with a corresponding outer wall 124b of the hollow plastic profile 112 into which the hollow chamber 24a of the aluminum hollow profile 24 is inserted. The aluminum hollow profile 24 is in turn only in contact with the heads 124aa of the curl projections 124a of the plastic hollow profile 112 and otherwise surrounded by an insulating layer of air. The same can be said of the longitudinally fixed fastening by rolling in the aluminum hollow profile 25, in which the receptacle 125 is bounded by the curl projections 125a and the outer wall 125b. The reinforced with the aluminum hollow profile 25 hollow plastic profile 112 has an undercut recess 133 for receiving locking and fitting elements. Unlike the undercut recess 131 of the plastic hollow profile 111, this is not formed exclusively by the hollow plastic profile, but by the combination of the hollow plastic profile 112 with the aluminum hollow profile 25. That is, the undercut recess is partially formed of components (outer wall, projection) 133b, 133a of the hollow plastic profile and partially of components (projection 25b) of the aluminum hollow profile 25. At the in Fig. 1 Shown embodiment, no reinforcing element is provided for secure attachment of the fitting and locking elements. This can, however, as with reference to the Fig. 2 and 3 is explained in various ways.

As can be seen from the description of the first embodiment, the hollow plastic profile allows, with a comparable overall depth, a significant increase in the proportion of the insulating zone in the overall structural depth. This is e.g. characterized in that the curl projections are on the corresponding outer side furthest protruding portions / parts of the hollow plastic profile.

If the reinforcing element is formed with a hollow profile, then the hollow profile is to be arranged so that it essentially (at least more than 50%) in the transverse direction x, preferably largely, ie 80% or more, more preferably 90% or more, even more preferably completely up to the outer wall relative to the projection of the curl projections, is arranged within the overall depth, preferably between the curl projections. The reinforcing elements or the hollow chambers 21a, 22a, 24a, 25a of the aluminum hollow profiles can preferably be used as a receiving area for receiving a corner joint.

The aluminum hollow profiles are preferably produced by aluminum extrusion, so that the cross section of the aluminum hollow profiles over the extension in the longitudinal direction is identical. In this case, the hollow profile and thus also the receiving area for receiving a corner joint in the manner described above between the Einrollvorsprüngen.

Hollow sections are not partially open profiles. Partially open profile in this sense means a profile which in cross-section (x-y) perpendicular to its longitudinal direction z has a shape (such as a U-shape or the like) which partially but not completely surrounds a space. Another example of a partial open profile would be a rectangle profile that is not completely closed on a rectangle side, and the like.

The plastic hollow profiles 111, 112 have a positionally accurate calibration of the curl projections relative to the outer geometry of the plastic hollow profiles, so that the aluminum hollow profiles or the receiving areas for corner joints positionally accurate relative to the outer geometry can be positioned by the longitudinally fixed curling. It follows that a positionally accurate connection of the reinforced hollow plastic profiles by corner joints or by other corner joints such. Welding is possible and the cost of reworking such corner joints is minimized.

The following is a method for producing the in Fig. 1 and Fig. 6 shown plastic hollow profiles described. In the WO 96/30188 A1 and from the DE 199 21 458 A1 Each method and apparatus for producing a hollow chamber profile are described with which individual parts or the entire hollow chamber profile can be calibrated positionally accurate. The plastic hollow profiles 111, 112 of the first embodiment are produced by appropriate methods, wherein materials are selected which are resistant to color, light and / or weather, as required. In this production, the Extruded profiles and preferably calibrated at least the outer surfaces and the roll-in projections accurately positioned. The materials used are hard PVC, PA, PET, PPT, PA / PPE, ASA, PA66 and others (each with or without reinforcing materials).

The reinforcing parts are preferably produced by aluminum extrusion. Preferably, the projections of the reinforcing parts to be rolled are prepared by knurling.

As foams for foaming the hollow plastic profiles thermosets such as PU can be used with appropriate density. Preferably, low density foams (0.01 to 0.3 kg / l) are used. If a high-density foam is to be used, foams of 0.3 to 0.6 kg / l are preferably used.

With the above written embodiment any undercuts are possible at any point of the profile. The surface treatment of exterior or interior linings made of aluminum or other materials can be carried out independently of a foaming process, which is advantageous if the foam tolerates no baking temperatures. In addition to this advantage, the described embodiment allows a system with very good mechanical properties, in which the reinforcement profiles can be used for corner connection by means of corner joints and at the same time the necessary post-processing is minimized. The embodiment also allows the use of different dense foams and the consequent optimization of thermal conduction properties.

The embodiment described allows portions of the insulating zone made of plastic at the total depth of 95% or more, in each case of 80% or more, with excellent mechanical properties, which is achieved by the longitudinally stable curling of the aluminum hollow sections.

With reference to Fig. 2 a second embodiment will be described. In the second embodiment, the sash profile is identical to the sash profile of the first embodiment, so that the description will not be repeated.

The frame profile has a plastic hollow profile 113, the structure of which corresponds to the hollow plastic profile 112 of the first embodiment, except for the formation of the recess 125 and the recess 134, in which a reinforcing element 27 is inserted.

As in Fig. 2 can be clearly seen, the outer wall 125b is not guided to the outer wall 133b, but passes just before the outer wall 133b in the wall 125c, which forms an outer wall for limiting the receptacle 125. As a result, the undercut recess 134 is formed, which is located on the inner side of the outer wall 133b opposite the undercut recess 133. In this undercut recess 134, a reinforcing element 27 is used, which is analogous to the reinforcing element 23 for secure attachment of fitting and locking elements, which are guided in the undercut recess 133.

The remaining structure of the plastic hollow profile 113 corresponds to that of the hollow plastic profile 112 of the first embodiment, so that the description is not repeated here.

With reference to Fig. 3 a third embodiment will be described. The sash profile of the third embodiment corresponds to the Sash profile of the first and second embodiments, so that the description will not be repeated here.

The frame profile of the third embodiment differs from the frame profiles of the first and second embodiments by the formation of the receptacle 126 and the aluminum hollow profile 26th

As in Fig. 3 can be clearly seen, the aluminum hollow section 26 is rolled on the room side of the frame profile in a known manner. The shape of the aluminum hollow profile 26 corresponds to that of the aluminum hollow profile 25, except for the projection 26c projecting in the width direction y on the space side of the aluminum hollow profile 26, which forms a reinforcing element extending in the transverse direction x and in the longitudinal direction z. A receptacle 126 is bounded by Einrollvorsprüngen 126 a, the tips 126 aa serve as Einrollvorsprünge for the projections 26 ba of the aluminum hollow section 26. For receiving the reinforcing element 26c, the receptacle 126 is provided with a recess extending in the transverse direction x and in the longitudinal direction z, which is bounded by a wall 126c, provided, so that the reinforcing element 26c as the reinforcing member 27 extends on the undercut recess 133 opposite the inside of the outer wall 133b. In this way, the reinforcing element 26 c can fulfill substantially the same function as the reinforcing element 27.

With reference to Fig. 4 A fourth embodiment will be described.

The fourth embodiment differs from the second embodiment in that the one-piece plastic hollow profiles 111 and 113 are replaced by multi-piece plastic hollow profiles 115 and 116. The remaining structure corresponds to that of the second embodiment. Unlike the plastic hollow profile 111, the plastic hollow profile 115 of the sash profile is not in one piece, but formed in several pieces. The outer walls 115a are joined by an inner member 115b forming inner webs (e.g., by plug, clip, or other connections, not shown). The use of the inner webs 115b increases the mechanical rigidity and leads to the formation of several hollow chambers. These hollow chambers can optionally be completely or partially foamed.

The plastic hollow profile 116, which replaces the plastic hollow profile 113 of the second embodiment, is formed in a similar manner. That is, the outer walls 116a are connected by an inner part 116b forming inner webs, forming a plurality of hollow chambers.

With reference to Fig. 5 A fifth embodiment will be described.

The fifth embodiment differs from the third embodiment in the structure of the plastic hollow profiles 115 and 117. The sash profile of the fifth embodiment corresponds to the Sash profile of the fourth embodiment, so that the description will not be repeated here.

The frame profile of the fifth embodiment has, in comparison to the frame profile of the fourth embodiment, instead of the aluminum hollow profile 25, an aluminum hollow profile 26, as in the third embodiment, on. The Kunststöffhohlprofil 117 of the fifth embodiment differs from the plastic hollow profile 116 of the fourth embodiment only in that no undercut recess for receiving the reinforcing member 27 is formed. Instead, the reinforcing member 26 c, which is an integral part of the aluminum hollow profile 26, on the inside of the outer wall 133 b, which forms the rear wall of the undercut recess 133.

Incidentally, the fifth embodiment corresponds to the fourth embodiment, so that the further description is omitted here.

The manufacturing method described in the first embodiment and the features and advantages described in the first embodiment remain applicable to the second to fifth embodiments. The features of the first to fifth embodiments can be freely combined as needed.
