Definitions

  • the present invention relates to a composite profile for the frame of a window, a door or similar.
  • the invention is intended for the fixed frame of a window or door, in which there is a turnable leaf with a glass panel for example.
  • the aim of the aforementioned insulating thermal bridge between the metal outer shell and inner shell is to prevent cold flows.
  • the presence of the thermal bridge means that large temperature differences can occur between the outer shell and inner shell, which in turn leads to undesired deformations.
  • each insulating strip with its longitudinally oriented edges is held in a groove of the outer shell and in a groove of the inner shell, whereby each groove is formed by parallel ribs separated by a distance, whereby after affixing the edges in the grooves, at least one rib is folded back in the direction of the other rib as a result of rolling in, in order to grip the edge concerned in the groove without any freedom of movement.
  • the outer shell heats up considerably on hot sunny days and the outer shell can thus expand considerably.
  • the inner shell on the other hand will expand significantly less, and as a result of the difference in thermal expansion between the outer shell and inner shell, the profile can warp.
  • a disadvantage is that the warping can impede or even prevent the closing of the window or door leaf.
  • Another disadvantage is that the warping can create openings between the frame and the leaf.
  • a disadvantage is that because of the freedom of movement in the direction transverse to the longitudinal direction of the strip, the stability of the leaf is reduced as a result, which is inconvenient during production, transport and mounting.
  • Improved insulation profiles are also known, such as "dilation" insulating strips that have a weakening in their axial direction, for example in the form of holes that are distributed along the longitudinal direction of the insulating strips, all such that the outer shell and inner shell can expand independently of one another, such that the warping is reduced or avoided.
  • a disadvantage is that these insulating strips are much more expensive than the conventional insulating strips.
  • the holes not only constitute a weakening in the longitudinal direction, but also in the transverse direction.
  • the purpose of the present invention is to provide one or more solutions to the aforementioned disadvantages and/or other disadvantages by providing a composite profile for the frame of a window, a door or similar, whereby the composite profile contains an outer shell and an inner shell that are connected together by at least one insulating strip, whereby the insulating strip is gripped in a groove of the outer shell and in a groove of the inner shell by its longitudinal edges, whereby each groove is formed by two ribs separated by a distance, whereby, after affixing the edges in the grooves, at least one rib is folded back in the direction of the other rib as a result of rolling in in order to grip the edge concerned in the groove, and whereby the rolling in is done such that a first longitudinal edge of the insulating strip is clamped in a first groove without any freedom of movement, while the second longitudinal edge of the insulating strip is held in the second groove, in such a way that this second edge has freedom of movement in the longitudinal direction of the groove, but no or practically no freedom of movement trans
  • An advantage is that the insulating strip firmly connects the inner shell and outer shell.
  • Another advantage is that under the influence of the thermal expansion of the outer shell, the insulating strip can move in the longitudinal direction of the groove such that the thermal expansion of the outer shell is somewhat compensated, and the composite profile does not warp.
  • the invention thus enables complex insulating strips, such as multi-chamber insulating strips with a number of chambers separated from one another, to be affixed between the outer shell and inner shell so that good insulation is obtained.
  • a composite profile can also be realised that combines a high mechanical strength with a high thermal insulation value, and which enables differential dilation between the outer shell and inner shell.
  • the rib that is folded back upon the rolling in of the first groove has a thickening or a protruding edge with respect to a corresponding roll-in rib of the second groove, and both ribs are folded back or rolled in to the same extent.
  • This thickening or protruding edge extends in the longitudinal direction of the roll-in rib because it form part of the profiling of the respective shell.
  • the invention concerns a composite profile for the frame of a window, a door or similar, whereby the composite profile contains an outer shell and an inner shell that are connected together by at least one insulating strip, whereby the insulating strip is gripped in a groove of the outer shell and in a groove of the inner shell by its longitudinal edges, whereby each groove is formed by two ribs separated by a distance and wherein the combination groove and edge of one of the outer shell and the inner shell is shaped so that free or practically free movement of this edge in this groove in longitudinal direction is possible and no significant play is present in the direction transverse to the longitudinal direction
  • Figure 1 schematically shows a first embodiment of a composite profile 1 according to the invention.
  • Such a composite profile 1 is primarily made from an outer shell 2 and an inner shell 3, preferably of aluminium, but other materials and in particular metals are not excluded according to the invention.
  • the composite profile 1 also has a thermal bridge 4 in the form of one or more insulating strips 5-6 that form a link between the aforementioned outer and inner shell 2-3.
  • both the outer and inner shell 2-3 are constructed in the form of hollow tubular profiles, with an outer chamber 7 and an inner chamber 8 respectively.
  • each insulating strip 5-6 there are a pair of ribs 9-10 for fastening each insulating strip 5-6.
  • ribs 11-14 are on the wall 15 oriented towards the inner shell 3, and each pair 9-10 of ribs defines a groove 16-17.
  • the wall 18 of the inner shell 3 oriented towards the outer shell 2 has similar ribs 19-22.
  • the aforementioned ribs 19-22 define two grooves 23-24 on the inner shell 3 that are opposite the grooves 16-17 of the outer shell 2 in the embodiment shown.
  • the ribs of the outer shell and inner shell are located opposite one another, it is not a strict requirement of the invention.
  • the insulating strip 5 in the example shown is produced as a single profile and is affixed with its longitudinal edges 25-26 in the respective groove 16 of the outer shell 2 and groove 17 of the inner shell 3.
  • a first longitudinal edge of the insulating strip is gripped in a first groove and this in such a way that the edge is secured without any freedom of movement.
  • the rib 19 of the aforementioned groove 23 has a thickening or protruding edge 27, as shown in more detail in figure 2 .
  • figure 2 clearly shows that, after rolling in, the edge of the insulating strip is firmly gripped between the ribs 19 and 20 of the groove 23.
  • the thickening 27 is on the side oriented towards the groove, but as the variant of figure 3 shows, it can also be the other side of the rib, or in other words the side oriented away from the groove has a thickening 27.
  • both sides of the rib it is also possible for both sides of the rib to have a protruding edge or thickening.
  • thickening 27 on the rib 19 can also be realised by making the other rib 11 thinner than the roll-in rib 19.
  • the other longitudinal edge 25 of the insulating strip 5 is held in a second groove 16, in this case a groove 16 of the inner shell 2, and this in such a way that this second edge 25 has freedom of movement in the longitudinal direction of the groove 16, as shown in figures 4 and 5 .
  • the contact surface between the insulating strip 5 and the roll-in rib 11 is formed by a folded edge that is specifically provided at the free end of the roll-in rib for this purpose.
  • the profiling of the roll-in rib after rolling in, matches the profiling of the edge 25 of the insulating strip 5, such that in this case there is a greater contact area between the insulating strip 5 and the roll-in rib 11.
  • the second insulating strip 6 can have an edge gripped in a first groove 24 and have its other edge affixed in a second groove 17, whereby the gripping in the first groove 24 does not allow any freedom of movement, while the other edge has some freedom of movement in the longitudinal direction of the second groove 17.
  • the method for manufacturing the composite profile 1 according to the invention is very simple and as follows.
  • an insulating strip 5 can be affixed between the outer and inner shell 2-3, whereby the one longitudinal edge 25 of the insulating strip 5 is placed in a groove 23 of the inner shell 3 and the other edge 26 in a groove 16 of the outer shell 2.
  • the insulating strip 5 must be connected to the aforementioned inner shell and outer shell 2-3 using a suitable roll-in tool.
  • At least one rib 11,19 of each groove 16,23 is folded back by the rolling in of the groove 16,23 in the direction of the other rib 12,20 in order to grip the edge concerned 25,26 of the insulating strip 5 in the groove 16,23.
  • Figure 6 clearly illustrates that the contact surfaces between the roll-in ribs 11,19 of the outer and inner shell 2-3, and the roll-in tool are located in the same plane, in this case a plane parallel to the longitudinal direction of the grooves 16,23.
  • the roll-in ribs 11,19 or in other words the ribs against which the roll-in tool is placed, is folded back to the same extent.
  • the thickening 27 on the roll-in rib 19 of the inner shell 3 means that the insulating strip 5 is more firmly gripped with its edge 26 in the groove 23 of the inner shell 3 than the other edge 25 in the groove 16 of the outer shell 2.
  • the presence of the thickening 27 on the roll-in rib 19 means that, after rolling in, the groove 23 of the inner shell 3 is more narrowed than the groove 16 of the outer shell 2.
  • the roll-in rib 11 After rolling in, the roll-in rib 11 is folded back such that the second groove 16 has a profiling that matches the profiling of the longitudinal edge 25 of the insulating strip 5, which is shown in figure 5 .
  • an adapted roll-in tool can be used, whereby the roll-in rib 19 of the one groove 23 is folded back to a greater extent than the roll-in rib 11 of the other groove 16, so that again the one groove is more narrowed than the other.
  • the greater folding back of one of the roll-in ribs means that the insulating strip is gripped in one of the grooves without any freedom of movement.
  • the insulating strip 5 is secured without any freedom of movement with respect to the inner shell 3, it is also possible that the insulating strip 5 is secured without any freedom of movement with respect to the outer shell 2. In this last case, the insulating strip 5 must be affixed in a groove of the inner shell 3 with a certain freedom of movement.
  • thermal bridge 4 can consist of only one or more than two insulating strips.
  • the insulating strip 5 is constructed as a hollow tubular profile, whereby the enclosed hollow space is subdivided or otherwise into chambers by partitions, in order to improve the thermal insulation.
  • Such a more complex insulating strip can be fitted with a number of flanges that are gripped in a number of grooves on the outer shell and inner shell.
