Description

The invention relates to a composite profile with the features of the preamble of claim 1. The composite profile is used in the construction sector as a window, door or façade profile and therefore suitable in particular for the production of windows, fixed glazing, doors or glass roofs. For this purpose, it comprises at least one metal profile as well as an insulator profile which is frictionally and / or positively connected to the metal profile.

Furthermore, the invention relates to a method for producing such a composite profile.

State of the art

Composite profiles of the aforementioned type are well known from the prior art. About the insulator or insulating a thermal separation between the metal profile and another metal profile and / or a substructure is effected so that it does not come to form a thermal bridge. The insulator or insulating profile is for this purpose made of a material which has a much lower thermal conductivity compared to metal. As a rule, plastic is used as material.

In order for the composite profile to be able to absorb high loads, a stable bond between the at least one metal profile and the insulator or insulating profile must be ensured. Furthermore, it is important to ensure that a stable bond over the entire life is given. The metal profile and the insulator or insulating profile are positively and / or positively connected thereto.

From the EP 2 476 853 A1 exemplifies a method for producing a composite profile for windows, fixed glazing, facades, doors or roofs, in which a non-positive and / or positive connection between a metal profile and an insulating profile is produced by plastic deformation of at least one profile section of the metal profile. In the profile section is a side boundary of a mounting groove, in which the insulating profile is used. By rolling the profile section to the insulating profile of the desired force and / or positive connection between the metal profile and the insulating profile is made. However, a stable bond is only ensured if the elastic spring back of the profile section is kept within narrow limits after rolling. In addition, sufficient rigidity must be provided to prevent bending of the mounting groove under load. In the EP 2 476 853 A1 is therefore proposed to connect to the groove-limiting profile sections adjacent and adjacent profile sections of the metal profile in the region of their adjoining each other. In particular, a cohesive connection by laser welding, roll welding, soldering or gluing is proposed, since by these connection methods from the outside invisible connection of the profile sections can be realized, so that smooth visible surfaces of the finished composite profile are maintained.

Based on the above-mentioned prior art, the present invention seeks to provide a composite profile comprising a metal profile and an insulator profile, which has a high dimensional stability and is also as simple and inexpensive to produce.

To solve the problem, the composite profile with the features of claim 1 and the method with the features of claim 14 are proposed. Advantageous developments of the invention can be found in the respective subclaims.

Disclosure of the invention

The proposed composite profile comprises a metal profile produced by forming, in particular by roll forming, from a sheet metal material with a profile cross section forming a groove and a web. The web is formed from profile sections which lie on each other at least in sections and in profile sections that limit the groove. The proposed composite profile further comprises a one-piece or multi-part executed insulator profile, which is partially received in the groove of the metal profile and non-positively and / or positively connected to the metal profile. According to the invention, the insulator profile and / or another profile received in the groove of the metal profile engage or engage pockets of the metal profile which are open towards the groove and which are arranged on both sides of the web. In this way, a cross-web clamping is achieved on the insulator profile and / or the further profile, which counteracts a bending of the insulator profile and / or the further profile receiving groove under load. Elaborate additional measures to prevent bending of the groove of the metal profile are therefore unnecessary. In particular, no material connection of the web-forming profile sections adjoining the groove-limiting profile sections is required.

By means of the clamping action of the insulator profile and / or of another profile received in the groove, an increased dimensional stability of the composite profile is thus achieved by simple means, which promotes a permanently stable bond.

If the insulator profile itself assumes the function of a clip, increased stiffness can be achieved even with insertion of the insulator profile in the groove of the metal profile, but at the latest with reshaping the groove limiting profile sections for producing the non-positive and / or positive connection of the insulator with the profile metal profile.

If the stapling function - as an alternative or in addition - is taken over by at least one further profile received in the groove, the at least one further profile can be inserted into the groove alone or together with the insulator profile. The latter requires that the at least one other profile - if there is still no connection - is first connected to the insulator profile. The connection can be realized for example by a simple plug-in, clamping and / or latching connection. The further profile preferably has a profile cross-section in the form of a clip or a bracket in order to simplify the connection of the further profile with the metal profile and / or the insulator profile.

The insulator profile of a composite profile according to the invention can not only be connected or connectable to a single further profile, but also with a plurality of further profiles or profile pieces. Preferably, the plurality of profiles or profile pieces are each arranged at a distance from one another behind one another and / or next to one another. The arrangement of several such profiles or profile pieces in a row requires that they are designed shorter in the profile longitudinal direction than the insulator profile.

In order to achieve the desired clamping effect, the pockets formed in the metal profile must have a sufficient depth. The depth is preferably measured parallel to a central longitudinal axis A of the metal profile, which in turn preferably extends centrally with respect to the groove and / or the web of the metal profile. This means that preferably the pockets extend substantially parallel to the central longitudinal axis A of the metal profile. Advantageously, the depth of the pockets is at least equal to or greater than the width of the pockets selected in the transition to the groove, so that a sufficient toothing of the insulator profile and / or the further profile is ensured with the metal profile.

Alternatively or additionally, it is proposed that the side boundaries of the pockets are formed running parallel to one another at least in sections, so that the insulator profile or further profile engaging therein is optimally supported via the parallel planar surfaces. Further preferably, the parallel portions of the side boundaries of the pockets are aligned parallel with respect to the web or web portions forming profile portions to achieve the desired stapling effect.

The insulator profile and / or the further profile receiving groove of the metal profile has a groove bottom and an opening, wherein preferably the opening facing the groove bottom. The pockets open towards the groove, into which the insulator profile inserted into the groove and / or the further profile engage or engage, can be arranged in the region of the groove bottom and / or in the region of the opening of the groove. In the area of the groove bottom arranged pockets have the advantage that the desired clamping effect already with insertion the insulator profile and / or the further profile can be achieved in the groove of the metal profile.

The insulator profile and / or the further profile preferably has or have a profile cross-section forming clamping noses. About the preformed clamping lugs a positive connection of the insulator profile and / or the other profile can be achieved with the metal profile in a simple manner, since the clamping lugs, for example, when inserting the respective profile in the groove of the metal profile, only brought into engagement with the pockets of the metal profile Need to become. Since the metal profile on both sides of the web arranged pockets, that is, at least two pockets, has, it is also proposed that formed on the insulator profile and / or on the further profile clamping noses form at least one pair of clamping noses, which is engageable with the arranged on both sides of the web pockets , In order to optimize the positive connection effected via the clamping noses, the cross-sectional shape of the clamping noses is preferably adapted to the cross-sectional shape of the pockets.

The clamping lugs of the insulator profile and / or the further profile preferably form clamping webs extending in the longitudinal direction of the profile. Furthermore, preferably, the pockets of the metal profile form longitudinal grooves extending in the profile longitudinal direction. In this way, a clamping effect over a partial length or over the entire length of the composite profile can be achieved.

The proposed clamping lugs and / or pockets are preferably formed with the same in the production of the respective profile, so that the measures required to achieve the desired clamping effect measures are largely cost neutral implemented.

Advantageously, the insulator profile of the proposed composite profile is at least partially or partially made of plastic. Plastic has a significantly lower thermal conductivity compared to metal, so that a thermal separation can be achieved via the insulator profile. The thermal separation prevents the formation of a thermal bridge, for example, when the metal profile is connected via the insulator profile with another metal profile.

In a further development of the invention, it is proposed that the insulator profile is made of at least two different materials, in particular two different plastics. For example, a portion or part of the insulator profile may be made of a material that has increased strength over a base material of the insulator profile. Preferably, this portion or this part of the insulator profile is engaged with the pockets formed in the metal profile in order to increase the stiffness in the region of the positive connection. That is, in particular, a clamping noses forming portion or a clamping noses forming part of the insulator profile is made of a material having increased strength. In addition, however, a reduced strength of the clamping lugs or a clamping lugs forming portion or part of the insulator profile may be desired to allow, for example, a plastic deformation of the clamping lugs when inserted into the pockets or when establishing the positive connection between the insulator profile and the metal profile. About the plastic deformation of the clamping lugs can then be ensured that the clamping lugs sufficiently deep into the pockets or fill the pockets as completely as possible.

As an alternative or in addition to the use of different materials, it is proposed that the insulator profile is connected to at least one further profile or to the further profile, wherein preferably the at least one further profile or the further profile is made of a different material than the insulator profile. The at least one further profile can be made, for example, from a further plastic or from metal. The use of a metallic material has the advantage that it usually has a high strength, so that it is particularly suitable for the formation of particularly dimensionally rigid clamping lugs. In addition, particularly small clamping nose cross-sections can be realized when using a metallic material.

The insulator profile and the at least one further profile can be positively, positively and / or materially connected. A material bond can be achieved, for example, by inserting the further profile into the mold during the production of the insulator profile.

Furthermore, it is proposed that the at least one further profile has a substantially U-shaped profile cross-section. The U-shape facilitates one Connection of the further profile with the insulator profile, since the further profile can be oriented such that the lateral legs of the U-shaped further profile embrace the insulator profile end. On the inner sides of the lateral legs also projections may be formed, which engage in the insulator profile, so that in addition a positive connection is achieved. Alternatively or additionally, it is proposed that the lateral legs are designed as spring arms, so that a positive connection can be achieved by subsequent attachment of the further profile to an end portion of the insulator profile. In turn, projections may be formed at the free ends of the spring arms, by means of which a positive connection with the insulator profile can be produced.

The U-shaped profile cross-section of the other profile can also be used to form clamping lugs. For this purpose, the further profile is oriented in such a way that the free ends of the lateral legs point in the direction of the pockets. Angled spring arms can also be formed at the free ends of the lateral limbs, so that the lateral limbs can be brought into clamping engagement with the pockets of the metal profile.

In addition, the further profile may have lateral limbs, each having free ends on both sides, so that on the one hand clamping lugs, on the other hand legs are formed for connection to the insulator profile.

The additional profile connected to the insulator profile can also be designed as a simple wire. The wire may have a round, oval or angular cross-section. For connection to the insulator profile, the wire can be inserted into the shape of the insulator profile during manufacture. If the cross section of the wire is only suitable for forming a single clamping nose, the insulator profile can also be connected to two profiles of the same cross section, so that both profiles together form a clamping nose pair.

To optimize the positive connection between the insulator profile and the metal profile of the wire or the wires may be made of a material that allows a certain plastic deformation when rolling the groove defining profile sections of the metal profile of the insulator profile, so that the wires in the both sides the web arranged pockets of the metal profile are pressed. As a material for the wires is therefore particularly suitable a comparatively soft metal, such as aluminum or an aluminum alloy.

The open towards the groove pockets of the metal profile have preferably been prepared by forming, in particular by roll forming, the groove defining profile sections. This means that the pockets can be formed with in the production of the metal profile with the same.

The profile sections of the metal profile delimiting the groove preferably each have an envelope or a flanging at the end, which engage behind an outer contour of the insulator profile. By the envelopes or flanges, the stiffness of the groove defining profile sections can be increased in particular in the region of the opening of the groove. Since the envelopes or flanges engage behind an outer contour of the insulator profile, a positive connection is also achieved, which counteracts a relative movement of the insulator profile relative to the metal profile in a direction perpendicular to the profile longitudinal direction. The curling also has the advantage that it forms a pocket suitable for receiving a clamping nose, which is arranged in the region of the opening of the groove. Preferably, a clamping nose of the insulator profile engages in this pocket.

Further preferably, the groove defining profile sections of the metal profile are partially compressed. The upsetting can be carried out during the forming, in particular roll forming, of the sheet material for the production of the metal profile. The upsetting leads to locally changed sheet thicknesses, wherein the sheet metal material can be moved so that sharp-edged inner contours are formed in the region of a sheet metal bend and / or in the region of a pocket. This means that by forming, in particular roll forming, also pockets with a rectangular cross-sectional shape can be produced. If a bag connects to a sheet metal bend with a sharp-edged inner contour, the bag can be widened because the sheet bending takes up less space.

The profile sections delimiting the groove are preferably compressed in the region of the groove bottom, since there is little space available for the formation of pockets due to multiple bends of the sheet metal material.

Preferably, the pockets have in cross-section a width b which is at least 0.2 mm. This means that over the entire depth of a bag a minimum width of 0.2 mm is not exceeded. Further preferably, the width b is at least 0.4 mm, so that correspondingly wide clamping lugs can be brought into engagement with the pockets. Towards the groove, the width of a pocket may increase, but preferably the side boundaries of a pocket extend at least in sections in parallel in order to achieve an optimum positive fit between the insulator profile or the further profile and the metal profile.

The groove of the metal profile is preferably symmetrical in cross section. That is, when rolling the groove defining profile sections of the insulator profile for producing the non-positive and / or positive connection with the metal profile, the nutbegrenzenden profile sections are uniformly deformed. The process is thus easier to control. The groove may for this purpose have a substantially triangular, trapezoidal, rectangular and / or at least partially round cross-sectional shape. In a substantially triangular or trapezoidal cross-sectional shape, the groove preferably widens in the direction of its opening to facilitate the insertion of the insulator profile into the groove. Since the groove-limiting profile sections are plastically deformed during rolling, a groove having an initially trapezoidal cross-section after rolling up can have a rectangular cross-sectional shape.

Further preferably, the web of the metal profile is arranged centrally with respect to the groove. In this way, a symmetry of the profile cross-section of the metal profile is achieved, which facilitates the formation of the arranged on both sides of the web pockets. The central longitudinal axis A of the metal profile in this case runs centrally with respect to the groove and centrally with respect to the web.

In a further development of the invention, it is proposed that the profile sections forming the web are connected via further profile sections. In this case, the further profile sections form a profile loop, which The profile loop makes it possible to produce the metal profile from a sheet-metal strip, which is preferably deformed in such a way that the free ends of the sheet-metal strip form the groove.

The further profile sections or the profile sections of the profile loop preferably form at least one flange. The flange contributes to an increase in the dimensional stability of the composite profile. Furthermore, the flange can be used for striking a glass element, a panel, a seal and / or another profile. Further preferably, the flange is oriented substantially perpendicular with respect to the web so that it forms a planar contact surface for a glass element, a panel, a seal and / or another profile. For example, the metal profile of the proposed composite profile may have a substantially T- or L-shaped profile cross-section. In addition, a variety of other cross-sectional shapes can be realized, which can be formed both symmetrically and asymmetrically with respect to the central longitudinal axis A.

The profile sections of the profile loop can lie on one another at least in sections. Through such sheet duplications, the stiffness of the metal profile and thus the composite profile can be further increased. Alternatively or additionally, individual profile sections of the profile loop can enclose a cavity or a chamber, so that the metal profile is designed at least in sections as a hollow profile. The stiffness of the metal profile is further increased in this way.

1. a) Bereitstellen eines Metallprofils, das durch Umformen, insbesondere durch Rollformen, aus einem Blechmaterial hergestellt worden ist und einen eine Nut und einen Steg ausbildenden Profilquerschnitt aufweist, wobei der Steg aus Profilabschnitten gebildet wird, die zumindest abschnittsweise aufeinanderliegen und in Profilabschnitte übergehen, welche die Nut begrenzen,
2. b) Bereitstellen eines einteilig oder mehrteilig ausgeführten Isolatorprofils, das in die Nut des Metallprofils abschnittsweise eingesetzt und mit dem Metallprofil kraft- und/oder formschlüssig verbunden wird.

To solve the problem mentioned above, a method for producing a composite profile according to the invention is also proposed. The method comprises the following steps:

1. a) providing a metal profile, which has been produced by forming, in particular by roll forming, from a sheet metal material and having a groove and a web forming profile cross-section, wherein the web is formed from profile sections, at least partially superimposed and pass into profile sections, which Limit groove,
2. b) providing a one-piece or multi-part executed insulator profile, which is inserted in sections in the groove of the metal profile and non-positively and / or positively connected to the metal profile.

According to the invention, the insulator profile and / or another profile, which is inserted into the groove of the metal profile before or together with the insulator profile, is brought into engagement with pockets of the metal profile which are open towards the groove and which are arranged on both sides of the web. About the insulator profile and / or further profile a clamping effect is achieved in this way, which counteracts a bending of the groove, since the web forming profile sections of the metal profile are held together on the standing in engagement with the two sides arranged pockets insulator profile and / or further profile.

The pockets have preferably been formed in the production of the metal profile by forming, in particular roll forming, so that no reworking of the metal profile for the production of the pockets is required. In order to create pockets with a substantially rectangular inner contour, the sheet material can be partially compressed during the forming or roll forming, in particular in the region of a groove bottom of the groove.

It is also proposed that the non-positive and / or positive connection of the insulator profile with the metal profile, the groove defining profile sections of the metal profile, preferably by rolling against the insulator profile, are plastically deformed. The plastic deformation of the groove-limiting profile sections can be used in particular for producing a positive connection. For this purpose, the insulator profile preferably has an outer contour which can be encompassed by the groove-limiting profile sections. The plastic deformation of the groove-limiting profile sections in the production of the positive and / or positive connection of the insulator profile with the metal profile can also be used to form pockets. This applies in particular to the formation of pockets which are arranged in the region of the opening of the groove. For example, the ends of the groove-limiting profile sections can each be provided with a flange, whereby pockets are formed in the region of the opening of the groove.

In order to bring the insulator profile and / or the further profile into engagement with the pockets of the metal profile, these preferably form clamping noses. The clamping lugs are preferably brought into engagement with these pockets when inserting the insulator profile and / or the further profile in the groove of the metal profile. Alternatively or additionally, in the production of non-positive and / or positive Connection of the insulator profile with the metal profile on the insulator profile and / or the further profile formed clamping lugs are brought into engagement with the pockets of the metal profile.

The clamping noses may in particular be such that they completely fill the pockets. The cross-sectional shape of the clamping lugs is adapted to the cross-sectional shape of the pockets. In addition, clamping lugs may be provided which are formed by angled spring arms of a profile and can be brought into clamping engagement with the pockets.

It is also proposed that the insulator profile and / or the further profile in the production of non-positive and / or positive connection of the insulator profile with the metal profile is at least partially, preferably in the range of standing in engagement with the pockets clamping noses, plastically deformed or become , By a plastic deformation of the clamping lugs of the clamping effect generating positive locking can be further optimized.

The sheet metal material from which the metal profile of the composite profile is produced, preferably has a sheet thickness of 1-3 mm, further preferably 1-2 mm. For example, the sheet thickness can be 1.5 mm. The sheet material may in particular be a sheet steel, as this favors a high dimensional stability of the composite profile.

Detailed description of the drawings

That in the Fig. 1 shown in cross-section composite profile comprises a metal profile 1, which has been produced by forming from a metal sheet and having a substantially T-shaped profile cross-section. The metal profile 1 forms a groove 2, which is bounded by profile sections 2.1, 2.2. In the groove 2, an end portion of an insulator profile 4 is accommodated, so that the groove 2 bounding profile sections 2.1, 2.2 of the metal profile 1 enclose the end portion. By means of envelopes 10 formed on the profile sections 2.1, 2.2 at the end, in addition, a positive connection is achieved since these each engage behind an outer contour 12 of the insulator profile 4.

To the groove 2 of the metal profile 1 includes a web 3, which is formed by profile sections 3.1, 3.2. These are connected via further profile sections 13.1, 13.2, 13.3 in such a way that a flange 13 is formed. In the region of the web 3 and the flange 13, the profile sections are flat on each other, so that over the sheet doubling increased stiffness is achieved. The metal profile 1 can also be formed in this way from a sheet metal strip.

The groove 2 limiting profile sections 2.1, 2.2 are repeatedly formed, so that a groove bottom 7 and side boundaries 14 are formed, which end in the envelopes 10 and define an opening 8 of the groove 2 in this way. In order to counteract bending of the groove 2, the groove-limiting profile sections 2.1, 2.2 form in the region of the groove base 7 pockets 6, in which clamping noses 9 of the insulator profile 4 engage. Since a pocket 6 is arranged on both sides of the web 3, a web-spanning clamping effect is achieved via the clamping lugs 9 of the insulator profile 4 that engage the pockets 6, which holds the web sections 3 forming profile sections 3.1, 3.2 under load.

In the Fig. 1 two clamping lugs 9 are provided, which are formed by the insulator profile 4 itself. The insulator profile 4 is continuously made of a material. In order to achieve an optimal clamping effect, the clamping lugs 9 have a minimum width, which is predetermined by a minimum width b of the pockets 6 (see also FIG Fig. 2 ). In the Fig. 1 is the width b 0.4 mm. In order to facilitate the insertion of the clamping lugs 9 in the pockets 6, the pockets 6 widen towards the groove 2.

In the Fig. 2 is a modification of the composite profile of Fig. 1 shown. The groove-limiting profile sections 2.1 2.2 have in the region of the groove bottom 7, in each case adjacent to a pocket 6, a flattening 15. This is due to a reduction in sheet thickness with simultaneous compression of the sheet material. While the profile sections 2.1, 2.2 have a sheet thickness s of 1.5 mm in the region of the side boundaries 14, the sheet thickness s' in the region of the sheet thickness reduction is approximately 1-1.2 mm. With the formation of the flats 15 at the same time a part of the sheet material was moved in the direction of the pockets 6, so that they have a rectangular cross-sectional shape. At the same time, the width b of the pockets 6 could be increased, so that this is 0.5 mm. Since an optimal support of the insulating profile 2 is effected via the rectangular cross-sectional shape of the pockets 6, the depth t of the pockets 6 can be made smaller. The depth t is here equal to the width b chosen.

Of the Fig. 3 is a further modification of a composite profile according to the invention can be seen. The clamping lugs 9 and the pockets 6 are not arranged in the region of the groove bottom 7, but in the region of the opening 8 of the groove 2 in this embodiment. To form the pockets 6, the ends of the groove-limiting profile sections 2.1, 2.2 have no envelopes 10, but flanges 11. The arranged in the opening 8 clamping lugs 9 not only counteract bending of the groove 2 under load, but also prevent springing back of the profile sections 2.1, 2.2 when rolling against the insulator profile. 4

A combination of the embodiments of Fig. 2 and the Fig. 3 is in the Fig. 4 represented, since both in the region of the groove bottom 7, as well as in the region of the opening 8 of the groove 2 pockets 6 are formed, engage in the clamping lugs 9 of the insulator profile 4. In this way, a maximum clamping effect is achieved, which counteracts a bending of the groove 2 under load and a springing back of the profile sections 2.1, 2.2 when rolling up.

The embodiment of Fig. 5 shows that the clamping lugs 9 need not necessarily be formed on the insulator profile 4. Because in the Fig. 5 the clamping lugs 9 are formed by a further profile 5, which is made of metal and inserted into the groove 2 of the metal profile 1. The further profile 5 is designed as a U-shaped spring clip, the side legs 5.1, 5.2 are bent end to form spring arms. The spring arms can be brought into clamping engagement with the pockets 6 of the metal profile 1. The spring arms accordingly form clamping lugs 9.

The inserted into the groove 2 further profile 5 can - as in the Fig. 6 shown - also be designed as an angle profile, which has a substantially U-shaped profile cross-section. The lateral legs 5.1, 5.2 of the profile 5 are used in this case, not only the formation of clamping lugs 9, but also the connection of the profile 5 with the insulator profile 4. The compound can be made prior to insertion of the two profiles in the groove 2 or only with insertion of the insulator profile 4. The profile 5 is also supported on groove side flats 15 of the profile sections 2.1, 2.2 of the metal profile 1.

In the embodiment of the Fig. 7 the further profile 5 is positively connected to the insulator profile 4. The positive connection is achieved via angled ends 16 of the lateral legs 5.1, 5.2, which engage in the insulator profile 4. To produce the positive connection, the further profile 5 may have been inserted in the insulator 4 with. The further profile 5 may also have been subsequently postponed to the insulator profile 4. In this case, the insulator profile 4 is designed in several parts and comprises a first part 4.1 and another part 4.2, which is formed by the further profile 5 (see also Fig. 8 ). The further profile 5 can be made for example of metal or plastic.

Of the Fig. 8 is a modification of the embodiment of the Fig. 7 refer to. The profile 5 is here supported on flats 15 of the groove 2 bounding profile sections 2.1, 2.2 of the metal profile 1. The formed on the profile 5 clamping lugs 9 have corresponding to the pockets 6 a rectangular cross-section.

In the embodiments of the FIGS. 9 and 10 the clamping lugs 9 are formed by the insulator profile 4, which is this sectionally made of a different material, in particular of a different plastic. The clamping noses 9 forming portion can thus be coextruded. In contrast to the embodiment of Fig. 9 has the metal profile 1 of the composite profile of Fig. 10 Bags 6, which have a rectangular cross-sectional shape. At the same time border on the pockets 6 flats 15. The nutbegrenzenden profile sections 2.1, 2.2 have been this area compressed.

Of the Fig. 11 is again a multi-part executed insulator profile 4, wherein a part 4.2 is formed by a profile 5 made of metal. The profile 5 forms clamping lugs 9, which engage in pockets 6 of the metal professional 1. The clamping lugs 9 are formed by lateral legs 5.1, 5.2, the other end are bent inwards to engage behind the outer contour 12 of another part 4.1 of the insulator 4. The multiple parts 4.1, 4.2 of the insulator 4 are therefore positively connected. The part 4.2 may be formed shorter than the part 4.1 in the profile longitudinal direction. For example, the part 4.2 may be a short profile piece. In this case, the insulator profile 4 may comprise a plurality of such short profile pieces, which are plugged or clamped spaced apart on the part 4.1.

The representations of the FIGS. 12 to 14 show that the formation of clamping lugs 9 and simple wires in the insulator 4 can be inserted with. Each wire forms a further profile 5, which is firmly connected to the insulator profile 4. The profile cross-section of such a profile 5 may, for example, be round ( Fig. 12 ), oval ( Fig. 13 ) or angular, in particular triangular ( Fig. 14 ), be. Deviating from the round shape profile cross-sections have the advantage that an optimum toothing of the profile 5 with the insulator profile 4 can be achieved. The wires can also be inserted as short pieces of wire in the insulator profile 4 with. The insulator profile 4 has in this case in the profile longitudinal direction a plurality of such pieces of wire, which are arranged spaced from each other in the longitudinal direction.

If the insulator profile 4 is connected to the formation of clamping lugs 9 with a further profile 5 or is connected, the further profile 5 may extend over the entire length of the insulator profile 4 or be formed shorter.

If the latter is the case, the further profile 5 is preferably a profile piece which is connected or connectable together with further identically designed profile pieces to the insulator profile 4.

The metal profile 1 of a composite profile according to the invention need not necessarily be formed symmetrically with respect to a central longitudinal axis A. Asymmetric embodiments of a metal profile 1 are exemplary in the FIGS. 15 to 18 shown.

From the representation of Fig. 15 For example, a metal profile 1 protrudes, which has a substantially L-shaped profile cross-section. The flange 13 is formed asymmetrically for this purpose.

Fig. 16 shows a further metal profile 1 with a substantially L-shaped profile cross-section. The web sections 3 forming profile sections 3.1, 3.2 are bent here several times, so that small loops 17 are formed, the grooves 18 limit. In the grooves 18, for example, sealing profiles can be used.

The metal profile of Fig. 17 represents a combination of metal profiles 1 of FIGS. 15 and 16 The left side corresponds to the metal profile 1 of Fig. 15 , the right side corresponds to the metal profile 1 of Fig. 16 , This leads to a flange 13 which has mutually offset profile sections 13.1, 13.2, 13.3, 13.4. In the region of the web 3, a groove 18 is also formed on one side, which is bounded by a loop 17.

That in the Fig. 18 illustrated metal profile 1 represents a modification of the metal profile 1 of Fig. 17 In order to avoid an offset in the region of the flange 13, a cavity 19 is formed on the left side, which is enclosed by the profile sections 13.1, 13.2, and 13.3 and by the profile section 3.2. In the profile section 13.3 also a groove 20 is incorporated centrally, which causes a visual outline of the front view.
