It is also important to ensure that there is a stable bond over the entire service life. For this purpose, the metal profile and the insulator or insulating profile are connected in a non-positive and / or positive manner.
  • From the EP 2 476 853 A1 is an example of a method for producing a composite profile for windows, fixed glazing, facades, doors or light 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.
  • the profile section is a side boundary of a fastening groove in which the insulating profile is inserted.
  • EP 3 048 232 A1 discloses a composite profile and a method with all features of the preambles of claims 1 and 14.

The arrangement of several such profiles or profile pieces one behind the other requires that they are made shorter than the insulator profile in the longitudinal direction of the profile.

  • the depth is preferably measured parallel to a central longitudinal axis A of the metal profile, which in turn preferably runs centrally with respect to the groove and / or the web of the metal profile. This means that the pockets preferably extend essentially parallel to the central longitudinal axis A of the metal profile.

The plastic deformation of the clamping lugs can then ensure that the clamping lugs engage sufficiently deep in the pockets or fill the pockets as completely as possible.
  • the insulator profile is connected to at least one further profile or to the further profile, the at least one further profile or the further profile preferably being 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 wire can have a round, oval or square cross section.
  • 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 lug, the insulator profile can also be connected to two profiles of the same cross section, so that both profiles together form a pair of clamping lugs.
  • the wire or the wires can be made of a material that allows a certain plastic deformation when the profile sections of the metal profile that delimit the groove roll onto the insulator profile, so that the wires enter into the two sides of the web arranged pockets of the metal profile are pressed. It is therefore particularly suitable as a material for the wires a comparatively soft metal, such as aluminum or an aluminum alloy.
  • the pockets of the metal profile open towards the groove have preferably been produced by reshaping, in particular by roll forming, the profile sections delimiting the groove. This means that the pockets can be designed at the same time that the metal profile is manufactured.

  • bags with a rectangular cross-sectional shape can also be produced by reshaping, in particular roll forming. If a bag connects to a sheet metal bend with a sharp-edged inner contour, the bag can be widened because the sheet metal bend takes up less space.
  • the profile sections delimiting the groove are preferably compressed in the area of the groove base, since there is little space available for the formation of pockets due to multiple bends in the sheet metal material.
  • the pockets preferably have a width b in cross section which is at least 0.2 mm. This means that a minimum width of 0.2 mm is not undershot across the entire depth of a pocket. Furthermore, the width b is preferably at least 0.4 mm, so that correspondingly wide clamping lugs can be brought into engagement with the pockets.
  • the width of a pocket can increase towards the groove, but the side boundaries of a pocket preferably run parallel, at least in sections, in order to achieve an optimal form 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. This means that when the profile sections delimiting the groove roll onto the insulator profile to produce the non-positive and / or form-fitting connection with the metal profile, the groove-delimiting profile sections are uniformly deformed. The process is therefore easier to control.
  • the groove can have an essentially triangular, trapezoidal, rectangular and / or at least sectionally round cross-sectional shape. In the case of a substantially triangular or trapezoidal cross-sectional shape, the groove preferably widens in the direction of its opening in order to facilitate the insertion of the insulator profile into the groove. Since the groove-limiting profile sections are plastically deformed when rolling on, a groove with an initially trapezoidal cross section can have a rectangular cross-sectional shape after rolling on.
  • the web of the metal profile is preferably arranged centrally with respect to the groove.
  • a symmetry of the profile cross section of the metal profile is achieved, which facilitates the formation of the pockets arranged on both sides of the web.

  • the flange contributes to an increase in the stiffness of the composite profile.
  • the flange can be used to attach a glass element, a panel, a seal and / or another profile.
  • the flange is preferably oriented essentially perpendicularly with respect to the web, so that it forms a flat contact surface for a glass element, a panel, a seal and / or a further profile.
  • the metal profile of the proposed composite profile can have an essentially T-shaped or L-shaped profile cross section.
  • a large number of further cross-sectional shapes can be realized, which can be designed both symmetrically and asymmetrically with respect to the central longitudinal axis A.

  • a clamping effect is achieved via the insulator profile and / or further profile, which counteracts bending of the groove, since the profile sections of the metal profile forming the web are held together via the insulator profile and / or further profile which is in engagement with the pockets arranged on both sides.
  • the pockets have been formed during the production of the metal profile by reshaping, in particular roll forming, so that no reworking of the metal profile is necessary to produce the pockets.

  • the representations of the Figures 12 to 14 show that simple wires can also be inserted into the insulator profile 4 to form clamping lugs 9.
  • 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 can, for example, be round ( Fig. 12 ), oval ( Fig. 13 ) or angular, especially triangular ( Fig. 14 ), his.
  • Profile cross sections deviating from the round shape have the advantage that an optimal interlocking of the profile 5 with the insulator profile 4 can be achieved.
  • the wires can also be inserted into the insulator profile 4 as short pieces of wire. In this case, the insulator profile 4 has a plurality of such wire pieces in the longitudinal direction of the profile, which are spaced apart in the longitudinal direction.
  • the further profile 5 can extend over the entire length of the insulator profile 4 or be of shorter design. If the latter is the case, the further profile 5 is preferably a profile piece which can be connected or connected to the insulator profile 4 together with other similarly designed profile pieces.
  • the metal profile 1 of a composite profile according to the invention does not necessarily have to be symmetrical with respect to a central longitudinal axis A.
  • Asymmetrical embodiments of a metal profile 1 are exemplary in the Figures 15 to 18 shown.
  • a metal profile 1 can be seen which has an essentially L-shaped profile cross section.
  • the flange 13 is designed asymmetrically for this purpose.
  • Fig. 16 shows a further metal profile 1 with an essentially L-shaped profile cross section.
  • the profile sections 3.1, 3.2 forming the web 3 are bent several times here, so that small loops 17 are formed which delimit the grooves 18.
  • sealing profiles can be inserted into the grooves 18.
  • the metal profile of the Fig. 17 represents a combination of the metal profiles 1 of the Figures 15 and 16
  • the left side corresponds to the metal profile 1 of the Fig. 15
  • the right side corresponds to the metal profile 1 of the Fig. 16
  • a groove 18 is also formed on one side, which is delimited by a loop 17.
  • Metal profile 1 shown represents a modification of the metal profile 1 Fig. 17
  • 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.
  • a groove 20 is also incorporated in the center, which brings about an optical structure of the front view.
