Definitions

  • the invention relates to a heat-insulating composite profile, in particular for window or door frames, with the features specified in the preamble of claim 1.
  • a heat-insulating composite profile of this type is known (DE-A-2 911 832), in which the insulating strip is held in the lower area by corresponding positive guides on the respective metal profile bars.
  • the construction known from DE-A-2 911 832 has the disadvantage that the intermediate webs and the continuous strips are overdetermined in practice with regard to their contact with the insulating strip.
  • the tolerances of the metal profile webs and the insulating strip mean that either the intermediate webs or the metal strips come into contact with the insulating strip.
  • the molding of the metal strips on the insulating strip results in a constraint within the insulating strip in the case of the metal strips being in contact with the insulating strip, which deforms until the intermediate webs also abut. This deformation can of course be different on the two profile sides, so that this deformation leads to inaccuracies in the composite profile, which affects the tolerances of the overall profile.
  • the invention has for its object to design a heat-insulating composite profile of the type mentioned in the preamble of claim 1 so that an accurate positional stability of the metal profile bars and the insulating strip is ensured despite the manufacturing tolerances and manufacturing inaccuracies of the components forming the composite .
  • the measures highlighted in this claim ensure that all the edge strips come with their lateral boundary surfaces to the non-positively against the inner wall of the metal profile bars.
  • the gap between the groove bottom of the receiving groove and the edge strip is very important, as this gap ensures that the edge strips are in contact with the intermediate webs in each case, and the edge strips are caused by a force that occurs during the pivoting and cold deformation of the inner web against the inner surface of the metal profile rod be pressed.
  • US-A-3 517 472 shows and describes composite profiles that do not fall under the preamble of claim 1, since these composite profiles have no intermediate webs that engage in corresponding grooves of the insulating strip.
  • the insulating strip is held only by the metal webs to be molded on both sides.
  • the dimensional accuracy of the entire composite profile depends on the tolerances of the insulating strip and the tolerances of the grooves in the metal profiles.
  • there is a compressibility of the insulating strip which also influences the dimensions of the composite profile. The more a metal bar is molded, the more the material of the insulating strip flows in this area. If the metal webs are shaped differently, the metal profiles will dislocate.
  • the insulating strip has edge strips in all corner regions, which, with their lateral boundary surfaces, bear non-positively on the inner wall of the metal profile bars.
  • the vertical bracing between the metal profile bars and the insulating strip also takes place on account of the non-deformable intermediate webs which engage in grooves in the insulating bar and the deformable continuous strips of the metal profile bars. Since only the continuous strips provided on the inside of the metal profile bars are deformed, the visible surfaces of the metal profile bars are kept parallel to one another. An offset in height is also prevented.
  • two or four cavities serving as air chambers are expediently provided within the insulating strip.
  • the composite profile consists of metal profile bars 1, 2; 1a, 2a and a profiled, dimensionally stable, plastic insulating strip 3 together.
  • the insulating strip in the exemplary embodiment according to FIGS. 1 and 2 has four cavities 4 designed as air chambers, the webs between the cavities 4 being designed as diagonals 5 of the insulating strip 3.
  • the insulating strip 3 is equipped with two cavities 4.
  • the insulating strip 3 On the profile bars 1, 2, 1a, 2a, in the upper area outside the insulating strip 3 connecting them, opposite, in the initial state, horizontal, continuous strips 6, 7, on the underside of which a continuous cam 8 is arranged. A corresponding recess 9 in the insulating strip 3 is assigned to the cam 8.
  • the insulating strip 3 has on its sides facing the metal profile bars 1, 2 in each case an obliquely upward groove 10, 11 directed into the interior thereof. Intermediate webs 12, 13 of the metal profile bars engage in these grooves. The clear width of the oblique grooves 10, 11 is substantially greater than the thickness of the intermediate webs 12, 13.
  • Each intermediate web 12, 13 has a continuous groove 14 at its transition point to the associated metal profile bar 1, 2, 1a, 2a, into which an edge strip 15 the insulating strip 3 engages with its tip. Furthermore, the insulating strip 3 has a nose 16 in the center on its underside, which serves as a stop when the composite profile is used as a window sash for the corresponding frame.
  • a lower hook-shaped bar 17, 18 is attached to each metal profile bar 1, 2, opposite the upper bars 6, 7.
  • Each strip 17, 18 already engages in a corresponding groove 19 of the insulating strip 3 in the untensioned state, which is shown in FIG. 1.
  • the web 20 of the bar 17, 18 is inclined at an angle of approximately 10 ° relative to the transverse plane 21 to the metal profile bar, while the angle between the inside of the hook 22 of the bar 17, 18 and the parallel plane 23 to the metal profile bar is approximately 20 ° is. Accordingly, the angle between the side walls of the groove 19 and the parallel plane 23 is approximately 20 °.
  • Both the transition from the inside of the hook 22 of the strip 17, 18 to the inside of the web 20 of the strip 17, 18 and the transition from the side wall of the groove 19 closest to the associated metal profile rod to the underside of the insulating strip 3 are rounded off .
  • the transitions from the bottom of the groove to its side walls are also rounded.
  • the transition from the top of the hook 22 of the strip 17, 18 to its back has a rounding.
  • the transition from the outside of the web 20 of the strip 17, 18 to the associated profile rod is rounded.
  • the thickness of the hook 22 of the bar 17, 18 corresponds to the thickness of the web 20 of the bar 17, 18.
  • a continuous groove 24 is embedded as a predetermined bending point at the connection point with the associated metal profile bar.
  • the end of the hook 22 of the bar 17, 18 engaging in the side wall of the groove 19 is pointed.
  • the upper ledges 6, 7 are pressed downward from their horizontal position shown in FIG. 1, so that the cams 8 with the depressions 9 in the insulating strip 3 come into engagement and, on the other hand, the lower hook-shaped strips 17, 18 are pushed up from their obliquely downward position into an approximately horizontal position, whereby the hooks 22 of the strips 17, 18 firmly attach the insulating strip to the corresponding inner wall 26 of the metal profile bars 1 , Press on 2.
  • the strips 6, 7 When the strips 6, 7 are deformed from the position shown in FIG. 1 into the position according to FIG. 2, the strips 6, 7 are pivoted about axes A.
  • the hook-shaped strips 17, 18 are pivoted about axes B.
  • the edge strips 15, 25 of the insulating strip 3 are non-positively fixed to the inner wall 26 of the metal profile bars with their lateral boundary surfaces 15a, 25a.
  • the insulating strip 3 is also pressed firmly onto the intermediate webs 12, 13, so that in addition to the frictional connection there is also a positive connection and a permanent, unchangeable connection of the individual components forming the composite is achieved.
  • cold-deformable webs 30 are provided which can be pivoted about an axis B and which delimit a receiving groove 28 on the inside.
  • An edge strip 25 of the insulating strip 3 is inserted into the receiving groove 28.
  • the starting position of the web 30 is shown in full lines in FIG. 3.
  • the end position of the web 30 is indicated in dashed lines.
  • the web 30 has a projecting cam 27 in the region of its free end on the side facing the edge strip 25.
  • the groove bottom 29 of the receiving groove 28 extends transversely to the inner wall 26 of the metal profile bar 2. Even after the web 30 has been formed, there is a gap between the edge strip 25 and the groove bottom.
