Definitions

  • the invention relates to a heat-insulating profile body, in particular for use in door or window frames or the like, consisting of two profile rails, preferably those made of metal, which are connected to one another by two profiled connecting strips made of heat-insulating material, the connecting strips being anchored in undercut grooves in the profile rails are.
  • the invention has for its object to design a heat-insulating profile body of the type described above so that it avoids the disadvantages mentioned above.
  • connecting strips are anchored in the undercut grooves with additional fastening elements, preferably those made of metal.
  • the additional fastening elements are effective directly in the area of the undercut grooves, i.e. they are directly involved in the anchoring.
  • Metal as a material for the additional fastening elements has the advantage that it can be processed in a simpler manner in some cases, but in any case in a more varied manner than the heat-insulating materials, such as plastic, which are normally used. It's also harder.
  • additional fastening elements made of metal and connecting strips made of heat-insulating material optimal introduction of force from the additional fastening elements into the profiled rails on the one hand and into the connecting strips on the other hand can be achieved due to the aforementioned properties.
  • the profile body produced according to the teaching of the invention also have the advantage that the cavity enclosed by the profile rails and connecting strips can - if desired - still be foamed in the known manner, the additional fastening elements being able to be designed in such a way that they correspond to the expanding foam mass also allow entry into the undercut grooves.
  • a first practical embodiment of the invention can consist in that the connecting strips are deposited in the undercut grooves with locking strips made of a soft, deformable material, which have been widened by upsetting after assembly.
  • each locking strip on the facing away from the respective anchoring leg Side of the connecting leg is inserted into the groove in question and is compressed continuously or at intervals along its edge facing the groove opening over its length.
  • Soft aluminum can preferably be used as the material for the locking strips.
  • the upsetting at intervals can take place, for example, by means of a gearwheel guided with pressure over the edge of the locking strip in question facing the groove opening.
  • Locking strips opposite one another on an insulating strip can be compressed by means of two gearwheels running in parallel, which simultaneously press the profile rails to fit the distance.
  • a second embodiment of the invention can consist in that the additional fastening elements are wedge-shaped.
  • each wedge-shaped fastening element can be located on the side of the connecting leg facing away from the respective anchoring leg between the corresponding groove wall and the mentioned side of the connecting leg can be driven.
  • the wedge-shaped fastening elements can be formed by wedge strips extending over the entire length of the profile body. But it is also possible that they consist of a large number of wedges which are spaced apart over the length of the profile body. In the latter case, foam can enter the undercut grooves through the spaces between the wedges if foaming of the cavity enclosed by the profile rails and connecting strips is desired.
  • the wedge strips or individual wedges and / or the corresponding groove walls and / or the corresponding sides of the connecting limbs of the connecting strips can be provided with longitudinal grooves in order to fix the driven-in wedge.
  • the application of the invention is particularly advantageous in the event that the connecting strips consist - seen in profile section - of rectangular flat strips, preferably of layer material such as hard paper.
  • This material is characterized by high strength, rigidity and heat resistance. It is also cheap.
  • it has the disadvantage that it can only be profiled to a very limited extent. This material cannot be shaped or processed in such a way that it has suitable end thickenings for engaging in undercut grooves, as is possible, for example, with insulating strips which are extruded from plastic.
  • This disadvantage is eliminated by using the teaching according to the invention in that the connecting strips are provided at their edges with recesses or holes in which the fastening elements can be anchored.
  • the fasteners then take over the engagement in the undercut grooves and optimally direct the flow of force from the profile rails into the connecting strips and vice versa.
  • the shape of the holes or recesses and their distance in the longitudinal direction of the connecting strips can be chosen so that an optimum is achieved for each special profile body with regard to the flow of force between the connecting strips and the profile rails.
  • a further embodiment can consist in that an undercut groove for receiving the fastening elements is provided in at least one of two on each profile rail and extends in the direction of the other profile rail Is webs and that one of the two webs is bent away from the other web before assembly and bent into an approximately parallel position to the other web after assembly.
  • undercut grooves are provided in each of the two webs and that the fastening elements extend into both grooves.
  • the fastening elements can be formed by cylindrical pins inserted into round holes in the connecting strips.
  • the undercut grooves - seen in section - can have a profile that tapers conically towards the bottom of the groove, the diameter of the blunt cylindrical pins at the ends being approximately equal to the groove diameter at approximately half the groove depth. This choice of the diameter of the pins ensures that the pins press into the groove wall when the other web is pressed against the first-mentioned web after assembly.
  • undercut grooves - seen in section - have a tapered profile against the bottom of the groove and that the cylindrical pins on their Ends to form at least three surfaces and cut edges at approximately the same angle as the grooves are pointed.
  • the pins should preferably be made of a harder material than the profile rails. If the profile rails are made of normal aluminum, the pins should be made of hard aluminum. The pins then press into the groove wall.
  • a fourth embodiment of the invention can, when applied to connecting strips, which - seen in profile section - are rectangular flat strips, consist in the fastening elements being formed by toothed strips, the teeth being inserted through holes in the connecting strips. Toothed strips have the advantage that they are quicker and easier to assemble.
  • the teeth can be rectangular or pointed at their front end.
  • the holes in the connecting strips can be elongated in the longitudinal direction of the profile body and have an approximately rectangular cross section.
  • the parts of the teeth that protrude from the connecting bar can be bent or twisted.
  • the continuous part of the toothed strip can be provided on the side of the connecting strip facing the L-shaped web, while the bent or twisted parts of the teeth on the other side of the connecting bar are supported on the straight web.
  • the bending or twisting of the parts of the teeth looking out of the connecting bar acts like riveting.
  • Connecting strips with toothed strips can be inserted into undercut grooves of the type described last in a simple manner in a tilted form and locked in place by erecting them.
  • the locking is done by the mentioned support of the bent or twisted parts of the teeth on the straight webs.
  • This type of assembly can also be called latching.
  • the edges of the connecting strips can be rounded off to make it easier to latch the swivel movement between the tilt position and the straight position.
  • Latching is also made easier when the bent-over parts of the teeth are rounded at the end in such a way that they roll on the straight web when the connecting bar is tilted.
  • recesses can also be provided on the edges of the connecting strips for the foam material to penetrate into the undercut grooves.
  • a fifth embodiment of the invention applied to the - seen in profile section - rectangular flat connecting strips can consist in the fact that the fastening elements are formed by toothed strips engaging in the holes or recesses in the connecting strips and having spring tongues engaging in the undercut grooves.
  • An embodiment of this fifth embodiment is that there is an undercut groove for receiving the spring tongues in at least one of two webs provided on each profile rail and extending in the direction of the other profile rail, that the undercut groove - seen in profile section from about to the connecting bar vertical and a groove flank extending from the base of the groove towards the associated profile rail is formed, and that the toothed strip - seen in profile section through the tooth area has approximately a U-profile, one U-leg forming the tooth, the other U-leg resiliently connecting strip engages under, and from the connecting leg connecting the two U-legs the spring tongues formed by incisions are bent out.
  • the spring tongues can have different lengths within tolerance limits.
  • the spring tongues, which are too long, are pressed into the plane of the connecting leg by the groove neck.
  • the spring tongues with the correct length engage behind the groove flank, which runs approximately perpendicular to the level of the connecting strip, and the spring tongues which are too short serve as a load reserve.
  • the force is introduced from the connecting strips into the additional fastening elements via the teeth of the toothed strip.
  • the force introduction from the additional fastening elements into the profile rails takes place via the spring tongues.
  • the size and spacing of the teeth and the holes in the connecting strips that receive them can be selected so that there is great tear-out resistance.
  • the spring tongues have sharp edges (which is not harmful for metal but causes a harmful notch effect for plastic), with which they can engage behind the undercut grooves in the metal profile rails in a positive and locking manner. Connecting strips provided with such toothed strips can therefore be made much slimmer than connecting strips made of plastic, on which end thickenings are formed for engaging behind the undercut grooves.
  • toothed strips with spring tongues Another advantage of the toothed strips with spring tongues is that the connecting strips do not have to be inserted into the grooves in the longitudinal direction of the profile body, but rather can be pushed directly into the grooves, the spring tongues forming a snap connection with the undercut grooves.
  • the assembly is therefore easier and less time consuming.
  • at least the web - seen in the profile section - that contains the groove for receiving the spring tongues can be beveled at the end.
  • the outwardly bent spring tongues can then slide along the slope, whereby they are first pressed into the plane of the connecting leg of the U-profile and after passing through the Can snap out the neck of the undercut groove.
  • the flat, cross-sectionally rectangular connecting webs in particular those made of layer material, such as hard paper, are only available in certain lengths (for example in the length of 2 m). If such connecting strips have been used at all (they were glued into the grooves), they were glued together at the joints.

  • each hole for receiving a U-shaped spring has a plane perforated wall that is perpendicular to the connecting strip plane and that is closest to the relevant edge of the connecting strip, and a distant oblique to the connecting strip that is located away from the relevant edge of the connecting strip.
  • Level running flat perforated wall has that the two U-legs of the spring enclose approximately the same angle as the two perforated walls, and that the grooves are formed by sawtooth-shaped grooves in profile section, which are located on the opposite sides of two on the The respective profile rail provided and protruding webs against the other profile rail, and that the end of a U-leg protruding from the hole forms a cutting edge intended for engagement in the grooves.
  • This sixth embodiment of the invention is also characterized in that the connecting strips can be pushed directly into the grooves.
  • the tips at the ends of the U-shaped springs protruding from the holes form a latching connection with the sawtooth-shaped grooves, in such a way that an insertion of the Connection strips in the grooves is possible, but no longer pulling out.

  • the cutting edge 55 engages in these grooves, and the arch on the base of the U-shaped spring 51 is also supported on these grooves.
  • the assembly is carried out by pushing the connecting bar 2o - seen in the sectional plane - from above between the two webs 25, 26.
  • the lower U-leg 53 of the spring 51 bends upward, while the upper U-leg 52 on the perforated wall 49 is present.
  • the cutting edge 55 can consequently slide from one groove 54 to the next lower one. If the female connector 2o is at the base of the recess formed by the two webs 25, 26, it can no longer be withdrawn, since the lower U-leg 53 is then supported on the lower perforated wall 5o. In this way, a rigid, stable connection is formed.
  • the pull-out strength of the connector strips is independent of the clamping force exerted by the undercut grooves on the metal fasteners.
