DETAILED DESCRIPTION OF THE DRAWINGS
[0064] The composite profile shown in cross section in FIG. 1 comprises a metal profile 1 that has been produced from sheet metal, by means of shaping, and has a substantially T-shaped profile cross section. The metal profile 1 forms a groove 2 that is defined by profile portions 2.1, 2.2. An end portion of an insulating profile 4 is received in the groove 2 such that the profile portions 2.1, 2.2 of the metal profile 1 that define the groove 2 surround the end portion. In addition, crimpings 10 formed on the ends of the profile portions 2.1, 2.2 achieve a positive connection, since said crimpings each engage behind an outer contour 12 of the insulating profile 4.
[0065] A web 3 adjoins the groove 2 of the metal profile 1, which web is formed by the profile portions 3.1, 3.2. Said profile portions are connected by further profile portions 13.1, 13.2, 13.3 such that a flange 13 is formed. The profile portions rest against one another in a planar manner in the region of the web 3 and of the flange 13, such that an increased inherent rigidity is achieved by the doubling of the sheet metal. The metal profile 1 can also be formed from a sheet metal strip in this manner.
[0066] The profile portions 2.1, 2.2 defining the groove 2 are shaped multiple times, so as to form a groove base 7 and lateral boundaries 14 that end in the crimpings 10 and thus define an opening 8 of the groove 2. In order to counteract upward bending of the groove 2, the profile portions 2.1, 2.2 defining the groove form pockets 6 in the region of the groove base 7, in which pockets clamping lugs 9 of the insulating profile 4 engage. Since a pocket 6 is arranged on either side of the web 3 in each case, the clamping lugs 9 of the insulating profile 4 that are engaged with the pockets 6 produce a clamp effect that extends across the web and holds together, when loaded, the profile portions 3.1, 3.2 that form the web 3.
[0067] Two clamping lugs 9 are provided in FIG. 1, which lugs are formed by the insulating profile 4 itself. In this case, the insulating profile 4 is manufactured from one material throughout. In order to achieve an optimal clamp effect, the clamping lugs 9 have a minimum width which is specified by a minimum width b of the pockets 6 (see also FIG. 2). In FIG. 1, the width b is 0.4 mm. In order to facilitate the insertion of the clamping lugs 9 into the pockets 6, the pockets 6 widen towards the groove 2.
[0068] FIG. 2 shows a modification of the composite profile of FIG. 1. The profile portions 2.1, 2.2 that define the groove comprise a flattening 15 in the region of the groove base 7, specifically adjacently to a pocket 6 in each case. This is the result of the sheet metal thickness being reduced and the sheet metal material simultaneously being compressed. While the profile portions 2.1, 2.2 have a sheet thickness s of 1.5 mm in the region of the lateral boundaries 14, the sheet thickness s in the region of the reduction in the sheet metal thickness is approximately 1-1.2 mm. By forming the flattenings 15, a part of the sheet metal material is simultaneously displaced towards the pockets 6, with the result that said pockets have a rectangular cross-sectional shape. At the same time, the width b of the pockets 6 could be increased so as to be 0.5 mm. Since the rectangular cross-sectional shape of the pockets 6 can bring about optimal support of the insulating profile 2, the depth t of the pockets 6 can be smaller. In this case, the depth t is selected so as to be equal to the width b.
[0069] A further modification of a composite profile according to the invention can be seen in FIG. 3. In this embodiment, the clamping lugs 9 and the pockets 6 are not arranged in the region of the groove base 7, but instead in the region of the opening 8 of the groove 2. In order to form the pockets 6, the ends of the profile portions 2.1, 2.2 defining the groove do not comprise a crimping 10, but instead beads 11. The clamping lugs 9 arranged in the region of the opening 8 not only counteract upward bending of the groove 2 when loaded, but furthermore prevent the profile portions 2.1, 2.2 from springing back during the process of roller-forming onto the insulating profile 4.
[0070] FIG. 4 shows a combination of the embodiments of FIG. 2 and FIG. 3, since pockets 6 are formed both in the region of the groove base 7 and in the region of the opening 8 of the groove 2, in which pockets clamping lugs 9 of the insulating profile 4 engage. A maximum clamp effect is thus achieved, which effect counteracts upward bending of the groove 2 when loaded, and springing back of the profile portions 2.1, 2.2 during roller-forming.
[0071] The embodiment of FIG. 5 shows that the clamping lugs 9 do not necessarily have to be formed on the insulating profile 4. In FIG. 5, the clamping lugs 9 are formed by a further profile 5 that is manufactured from metal and is inserted into the groove 2 of the metal profile 1. The further profile 5 is formed as a U-shaped spring clip, the lateral limbs 5.1, 5.2 of which are angled at the ends thereof so as 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.
[0072] The further profile 5 inserted into the groove 2 can, as shown in FIG. 6, also be formed as an angle section having a substantially U-shaped profile cross section. In this case, the lateral limbs 5.1, 5.2 of the profile 5 not only form clamping lugs 9, but furthermore also connect the profile 5 to the insulating profile 4. The connection may have been established prior to inserting the two profiles into the groove 2, or may be established only when the insulating profile 4 is inserted. The profile 5 is in addition supported on groove-side flattenings 15 of the profile portions 2.1, 2.2 of the metal profile 1.
[0073] In the embodiment of FIG. 7, the further profile 5 is positively connected to the insulating profile 4. The positive connection is achieved by means of angled ends 16 of the lateral limbs 5.1, 5.2 which engage in the insulating profile 4. In order to establish the positive connection, the further profile 5 may have also been inserted into the of the insulating profile 4. However, the further profile 5 may also have been subsequently pushed onto the insulating profile 4. In this case, the insulating profile 4 is formed in multiple parts and comprises a first part 4.1 and a further part 4.2 that is formed by the further profile 5 (see also FIG. 8). The further profile 5 may be manufactured from metal or plastics material for example.
[0074] A modification of the embodiment from FIG. 7 can be seen in FIG. 8. In this case, the profile 5 is supported on flattenings 15 of the profile portions 2.1, 2.2 of the metal profile 1 that define the groove 2. The clamping lugs 9 formed on the profile 5 have a rectangular cross section, in accordance with the pockets 6.
[0075] In the embodiments in FIGS. 9 and 10, the clamping lugs 9 are formed by the insulating profile 4 which, in this case, is manufactured from a different material, in particular a different plastics material. The portion forming the clamping lugs 9 can thus be coextruded. Unlike the embodiment in FIG. 9, the metal profile 1 of the composite profile of FIG. 10 comprises pockets 6 that have a rectangular cross-sectional shape. Flattenings 15 also adjoin the pockets 6. For this purpose, the profile portions 2.1, 2.2 that define the groove have been compressed in regions.
[0076] FIG. 11 again shows an insulating profile 4 formed in multiple parts, a part 4.2 being formed by a profile 5 made of metal. The profile 5 forms clamping lugs 9 which engage in pockets 6 of the metal profile 1. The clamping lugs 9 are formed by lateral limbs 5.1, 5.2 which are bent inwards at the other end in order to engage behind the outer contour 12 of a further part 4.1 of the insulating profile 4. The multiple parts 4.1, 4.2 of the insulating profile 4 can thus be positively connected. The part 4.2 can be shorter than the part 4.1 in the longitudinal direction of the profile. For example, the part 4.2 may be a short profile section. In this case, the insulating profile 4 may comprise a plurality of short profile sections of this kind which are pushed or clamped onto the part 4.1 so as to be mutually spaced.
[0077] The illustrations in FIGS. 12 to 14 show that simple wires can also be inserted into the insulating profile 4 at the same time, in order to form clamping lugs 9. In this case, each wire forms a further profile 5 that is rigidly connected to the insulating profile 4. The profile cross section of a profile 5 of this kind may for example be circular (FIG. 12), oval (FIG. 13) or angular, in particular triangular (FIG. 14). The advantage of profile cross sections that deviate from a circular shape is that it is possible to achieve optimal interlocking of the profile 5 with the insulating profile 4. The wires can also be inserted into the insulating profile 4 at the same time, as short wire pieces. In this case, the insulating profile 4 comprises a plurality of wire pieces of this kind in the longitudinal direction of the profile, which wire pieces are mutually spaced in the longitudinal direction.
[0078] If the insulating profile 4 is connected to a further profile 5 in order to form clamping lugs 9, the further profile 5 may extend over the entire length of the insulating profile 4 or may be shorter. In the latter case, the further profile 5 is preferably a profile section that is or can be connected to the insulating profile 4 together with other similarly designed profile sections.
[0079] The metal profile 1 of a composite profile according to the invention does not necessarily need to be symmetrical with respect to a central longitudinal axis A. Asymmetrical embodiments of a metal profile 1 are shown by way of example in FIG. 15 to 18.
[0080] For example, the illustration in FIG. 15 shows a metal profile 1 that has a substantially L-shaped profile cross section. For this purpose, the flange 13 is asymmetrical.
[0081] FIG. 16 shows a further metal profile 1 having a substantially L-shaped profile cross section. In this case, the profile portions 3.1, 3.2 forming the web 3 are bent multiple times in order to form small loops 17 which define grooves 18. Sealing profiles, for example, can be inserted into the grooves 18.
[0082] The metal profile of FIG. 17 is a combination of the metal profiles 1 from FIGS. 15 and 16. The left-hand side corresponds to the metal profile 1 of FIG. 15, and the right-hand side corresponds to the metal profile 1 of FIG. 16. This results in a flange 13 comprising mutually offset profile portions 13.1, 13.2, 13.3, 13.4. In addition, a groove 18 that is defined by a loop 17 is formed on one side, in the region of the web 3.
[0083] The metal profile 1 shown in FIG. 18 is a modification of the metal profile 1 of FIG. 17. In order to prevent an offset in the region of the flange 13, a cavity 19 is formed on the left-hand side, which cavity is surrounded by the profile portions 13.1, 13.2 and 13.3, and by the profile portion 3.2. In addition, a channel 20 is made in the centre of the profile portion 13.3, which channel provides an optical division of the front view.
