Definitions

  • Spacer frames for insulating glass panes usually consist of hollow profile bars made of aluminum or stainless steel, which contain a free-flowing desiccant, usually molecular sieves. It is the job of the desiccant in the Insulating glass pane to bind existing moisture, so under the on windows occurring temperatures the dew point is not fallen below.
  • the metallic Spacer frames are today mostly bent and in one piece are characterized by good mechanical stability. However, you have that Disadvantage that they, especially if they are made of aluminum, a cold bridge form between the individual glass panes of the insulating glass pane.
  • Spacer frames are also used to reduce the effectiveness of the cold bridge known from metallic U-profiles and from thermoplastic solid profiles, wherein the latter are extruded directly onto a sheet of glass.
  • Spacer frames have also been proposed recently, which are made of Hollow section bars are made of glass fiber reinforced plastic and likewise like spacer frames made of hollow metal profiles with a granular, free-flowing desiccants can be filled.
  • the glass fiber reinforced plastic has only a low thermal conductivity, so that it desirably improves heat transfer between the individual glass panes of an insulating glass pane. Due to the glass fiber reinforcement, the hollow profile also has sufficient mechanical stability.
  • the present invention has for its object to show a way how to produce sufficiently stable spacer frames made of glass fiber reinforced hollow plastic profiles at competitive costs.
  • the spacer frame according to the invention is an angular frame. In most Cases are the legs of the frame formed between the corners form a right angle with each other, but this is not mandatory.
  • the spacer frame can also have corners where its legs meet Include angles that are smaller or larger than 90 °.
  • the hollow profile is cut to form the corners. in the finished spacer frame, there are incisions, which are through the inner vertex of the respective corner and from there further towards the Extend the outer vertex of each corner without closing the outer vertex cut through. Under the inner vertex, the one facing the inside of the frame Understand the vertex of a corner.
  • the outer apex rests the frame outside the corner.
  • the incision provided on one corner enables it to form the corner by bending without material of the inside of the frame To displace profile wall and the flanks of the hollow profile rod.
  • By not cutting the outer vertex of the corner hang the legs of the spacer frame starting from the corner in one piece over the outer vertex. That was done through the incision Weakening of the hollow profile is compensated for in that in the hollow profile rod there is a dimensionally stable elbow that stabilizes the respective corner.
  • a dimensionally stable elbow is understood to be one that holds the corner stabilized so far that the spacer frame when handling the until the completion of installation in an insulating glass pane are required, its wanted at the corners, predetermined by the shape of the insulating glass pane Maintains angle.
  • the spacer frame according to the invention can be rationally manufactured, which at the discussion of the method according to the invention will become clear.
  • the incisions extending from the inner vertex to the outer vertex preferably end in front of the outer apex.
  • Hollow profiles for spacer frames usually have a cross section that is different from a rectangle differs in that two adjacent corners, namely those on the outside of the later spacer frame are chamfered.
  • the incisions preferably end on Transition from the flanks to the inclined surface or in the inclined surfaces without however, to injure the outer profile wall.
  • the profile outer wall and the Provide sloping surfaces with a water vapor barrier then the incisions end already at the transition to the inclined surfaces so as not to block the vapor to hurt.
  • the contra-angle consists of a plastic and can contain fillers. With It is advantageously injected into the hollow section bar.
  • the advantage here is that the elbow while forming the corner or afterwards into the hollow section bar can be injected and that it fits positively with the inside during injection of the hollow profile, with grooves and ridges present there can do what is optimal for stabilizing the corner.
  • Fillers in the plastic shrinkage can counteract the contra-angle. Suitable fillers are known per se. This can also be used as a filler in the spacer frame Desiccants used are used.
  • the contra-angle there are one or more Accesses, preferably only one access in one of the two flanks of the hollow profile educated.
  • the entrances are preferably through the injected elbow closed again.
  • the flanks of the hollow profile rod remain also essentially flat and tightly closed in the corner area.
  • the approaches for the injection of the elbow are preferably such that they are Cover and penetrate incisions. This has the advantage that the Plastic for the contra-angle from there evenly in both from the corner can distribute outgoing legs of the hollow profile rod. It can also on this way the incision itself is used for injecting the plastic become.
  • the contra-angles should extend from the corner into the adjacent one Extend the legs so that good stabilization is achieved.
  • the corner brackets extend 2 to 5 cm, in particular approximately 3 cm deep into the legs of the spacer frame.
  • the cavity required for this is ensured by the stoppers which the desiccant between to lock myself in.
  • the plugs are preferably a composite of one thermoplastic, especially an adhesive, with the desiccant Such a plug has the advantage that it can be easily injected of the plastic in a suitable place in the desiccant and connects sufficiently firmly to the inner walls of the hollow profile. At the same time the plug seals the thighs towards the incisions which are necessary for the formation of the corners are created. Because it makes it possible to fill and cut (Notched) hollow section bars still in the extended position for some time intermediate storage before they are processed into finished spacer frames, without losing the moisture-binding capacity of the desiccant.
  • a spacer frame which consists of a hollow profile bar is made of glass fiber reinforced plastic
  • Appropriate procedures for this and devices are known to the person skilled in the art from filling metallic hollow profile bars known.
  • the desiccant is preferably at least initially secured at one of the ends of the hollow profile rod against trickling out, e.g. by injecting a thermoplastic adhesive or by Insert a straight plastic connector, with which the Hollow section bar after creating the necessary corners to form a frame is closed.
  • the hollow section rod filled with the desiccant then becomes open on both sides of the point intended for a corner, preferably on a flank, and a material is injected, in particular a thermoplastic Adhesive, which forms a plug in the hollow profile rod. Then it will be the hollow profile rod at the point intended for the corner from the later inside the spacer frame in the direction of the later outer Notch of the corner: It becomes an angled, essentially wedge-shaped Cutout formed, the angle of which depends on the angle of the to be formed Corner is selected.
  • the notching can be done with two saw cuts or done by milling.
  • the hollow profile rod is released, that is between the desiccant previously formed is accessible and removed, preferably suctioned off, preferably completely, it being for the further process steps is also portable if a small residual amount of the desiccant remains between the notch and the plug.
  • the hollow profile rod On the notched point is the hollow profile rod by the desired angle of Bent corner and thereby formed the corner. Bump at the end of the bending process the edges of the profile inner wall to form the inner vertex of the corner together. Preferably, they also bump into the flanks by notching formed edges together. As a result of the notching, there is no need for any bending Material of the hollow profile rod are displaced. It can therefore also be there not to an uncontrolled breaking of the glass fiber reinforced plastic come.
  • the material On the outside of the profile, the material is bent and slightly open The more the cut when notching takes place, the less the stress is on the train is approximated to the profile outer wall.
  • this is preferably done before bending and / or during bending warmed, e.g. by putting on a heated body, which is preferably a component a bending tool, or by blowing with hot air, which is because the low heat capacity of the thin hollow profile wall (it is no more than approx. 1 mm thick) quickly leads to success.

  • the notch end there with a tip Preferably leaves but the notch ends end at a distance in front of the profile outer wall. In this case it is preferred that the notching does not end in a tip, but rather dull. This favors the formation of a smooth profile flank in the corner area. This can also be promoted by using the hollow profile rod clamped in the vicinity of the notch between jaws and during bending and injecting the elbow between the jaws leaves so that no material can be displaced to the outside.
