Definitions

  • the application relates to extruded plastic hollow profile bars for sash and window frames of windows and doors with a subsequently inserted reinforcing hollow profile bar made of metal, which rests at least on part of its circumference on the chamber of the plastic bar receiving it.
  • the plastic rod can consist of all-plastic, it can also consist of foam plastic or, as is particularly advantageous in many cases, of integral foam with an outer and preferably also an internal integral skin which is essentially non-porous.
  • the reinforcement hollow profile rod is usually made of aluminum or steel.
  • the extruded plastic hollow profile bar is first cut to the correct length and mitred. Then the reinforcing metal rod is inserted into the hollow profile rod. The bars forming the frame are then connected to one another at the corners. This is usually done by welding the plastic.
  • the invention has in particular the object of further developing the initially outlined hollow section bar according to the preamble of claim 1 in such a way that in all cases a sufficiently tight fit of the inner surface of the hollow section bar on the outer surface of the hollow, stiffening metal bar is achieved.
  • the hollow chamber of the plastic rod receiving the metal rod is provided with a longitudinal slot which opens the chamber to the outside, that bent lips are provided on the edges of the longitudinal slot - preferably outwards - and that the longitudinal slot from one - preferably also from Metal existing cover strip is covered, which - preferably with edge ribs - overlaps and holds the lips together.
  • the lips it is also possible for the lips to protrude into the hollow chamber.
  • the cover strip e.g. U-profile and a corresponding longitudinal recess is provided in the metal rod, the cover strip can be inserted with its groove outwards into the slot, so that it clamps the lips between them and the flanks of the recess of the metal rod.
  • the hollow profile made of plastic can be brought so far into contact with the metal rod via the metal stiffening rod, which is very stiff and dimensionally stable in comparison with the plastic hollow profile, by tightening the edges of the longitudinal slot that even with relatively large dimensional deviations, the plastic rod still lies sufficiently against the metal rod.
  • the largest hollow, as a rule, on the inner walls receiving the metal rod Chamber of the plastic hollow profile rod run longitudinal ribs that are relatively easily deformable without the plastic hollow profile being deformed in its entirety.
  • Another advantage of these longitudinal ribs is that they keep the sliding resistance low when the metal rod is inserted into the plastic rod. Even if the plastic rod is too narrow, the backs of these longitudinal ribs can be scraped off the front of the metal rod, which also leads to a secure hold.
  • the cover profile strip can be made of plastic. This is especially true when it is snapped behind the lips on the edge of the slot.
  • the cover profile strip is to be connected to the metal rod by means of fastening elements such as screws or explosive rivets
  • the cover strip will preferably be made of metal.
  • a snap-in connection can also be sufficient.
  • the rigidity of the entire rod is increased significantly, so that in many cases the metal rod inserted into the hollow chamber can be manufactured with a smaller wall thickness than was previously necessary.
  • Another advantage of such a clamping is that one can do without the previously usual fastening of the metal profile bar to the plastic profile by means of self-tapping screws.
  • the training is advantageously made so that the edge ribs are locked behind the lips of the slot.
  • the edge ribs always attack the lips with pre-tension and endeavor to press them against each other or against an intermediate layer, which can advantageously also be formed by the metal rod.
  • the chamber of the plastic rod which holds the metal rod is surrounded on at least part of its circumference by air chambers or integral foam walls and calibrated on its corresponding surfaces.
  • a polyvinyl chloride or a corresponding polyblend which is common for window bars, will be used as the material for the - preferably thermoplastic - plastic hollow profile bar. It is essential that the plastic is thermoplastic if the most desired welding is to be carried out at the corners. However, the corner connection can also be effected without welding, for example by corner brackets inserted into the metal hollow profile bars and mechanical fastening thereof or adhesive bonding thereof.
  • the inner wall of the chamber receiving the metal rod can also contact the calibration element during the calibration, which can be held from the side through the slot, despite the necessary external calibration of the plastic profile .
  • This is an important advantage, since the charging of an internal calibration element with cooling water through the torpedo of the nozzle presents considerable difficulties. The invention avoids this.
  • the metal rod also has a longitudinal slot, which is present from the outset, for example, in the case of metal hollow profile rods produced by roll forming from sheet metal. If you ensure that this longitudinal slot of the metal rod has a certain width of, for example, one millimeter and arrange this slot on the opposite side of the slot of the plastic rod, the insertion is particularly easy because on the side where the chamber is practical cannot stretch, the metal rod is relatively easy to compress, while on the opposite side, where the metal rod is not compressible, the hollow plastic profile rod can easily give out through the slot.
  • the Metal rod with a part of its circumference in the slot, so that the lips are clamped between the edge ribs and the flanks of this circumferential part. Since the cover strip is preferably connected to the metal rod by means of screws or the like, an extraordinarily firm clamping is achieved in this way not only of the cover strip with the metal rod, but also of the plastic profile rod with the metal rod and the cover strip.
  • the profile of the cover strip is inserted into the slot, so that the lips are clamped between the edge ribs and the flanks of the indentation.
  • the last-mentioned embodiment with an inserted cover strip also has the great advantage that the indentation can also be designed as a guide for fitting parts of the frame.
  • cover strip and the metal rod are drilling and cutting sheet metal screws seen. These can be provided at intervals of, for example, 15 to 20 cm.
  • cover strip and the metal rod are not made of aluminum or an aluminum alloy but of steel, these elements are preferably galvanized.
  • a metal rod with a closed hollow profile is of course optimal in terms of strength.
  • the roll-formed metal bar with a narrow longitudinal cut also offers advantages, as explained above.
  • sealing compound e.g. silicone-based. Sealing the grooves may also be appropriate.
  • the profile bar shown in FIG. 1 can be used, for example, to produce a frame, in which case the profile projection located at the top right has the function of a stop bar, while the outer grooves visible on the left of the profile serve to accommodate holding elements for the frame.
  • FIG. 1 shows an outer plastic hollow profile rod 1, into which a metal stiffening rod 2 is inserted on the inside.
  • a cover strip 3 can also be seen.
  • the plastic hollow profile rod 1 has a large central receiving chamber 4 for the metal rod 2.
  • the receiving chamber 4 has a substantially rectangular profile and is open to the outside through a slot on its left side, in which it is only surrounded by a simple wall.
  • the metal hollow profile rod 2 formed by roll forming from sheet metal has a corresponding protuberance 2a, with which it protrudes outwards through the slot in the wall of the hollow chamber 4 to approximately the level of the free end of the lips 5, which there outwards to the edges of the slot connect.
  • the lips 5 are formed by webs or ribs, the surfaces of which face away from each other near the free end are somewhat more apart than near the attachment to the corresponding wall 6 of the hollow chamber 4.
  • the cover strip 3 is also formed like the metal rod 2 from roll-formed sheet metal and has essentially a flat U-profile, which overlaps the two lips 5 from the outside with its two legs and against each other and thus also against the two outer side surfaces of the projection 2a of the profile rod 2 presses.
  • the main chamber 4 of the profile rod 1 is separated from the outer surface of the profile rod 1 by an air chamber 7 at the top, by an air chamber 8 on the right and by an air chamber 9 at the bottom. This makes it possible to cleanly calibrate the three surfaces of the main chamber 4 adjacent to the chambers 7, 8 and 9 when extruding the profile rod 1, so that very close tolerances are possible both for the dimensions of the main chamber 4 and for the external dimensions of the rod 2 .
  • the free edges of the legs of the U of the profile of the cover strip 3 are slightly closer to one another than the roots of the cover strip which attach to the web of the U of the cover strip 3. As a result, the cover strip 3 can be snapped on. It is connected to the metal profile rod 2 by self-drilling and self-tapping self-tapping screws arranged at intervals of 15 cm from one another. These connecting screws are indicated at 10 by a center line.
  • the window bar shown in profile in FIG. 2 can be used, for example, to form a casement.
  • the stop bar 21 is provided on the hollow plastic profile rod 20 in Fig. 2 bottom left.
  • the nose 22 visible at the top right can be used together with a retaining strip inserted into the groove 23 to hold the glazing, but also, for example, to hold a door panel.
  • the plastic hollow profile 20 apart from the small chambers in the strips 21 and 22, has only a single large hollow chamber 24 into which a steel stiffening profile, which is in principle rectangular, is inserted.
  • the steel stiffening profile 25 is also made of sheet metal by roll forming.
  • the free slot is arranged opposite the slot 26 in the wall of the hollow chamber 24 of the plastic profile.
  • the hollow chamber of the plastic profile is not internally calibrated. It therefore carries the usual and known support ribs 27 against which the metal profile rod 25 should rest.
  • the wall 28 of the hollow chamber 24 on the left in FIG. 2 is interrupted, as can be seen, by a longitudinal slot.
  • ribs which also project here as lips 30, extend essentially vertically from the plane of the wall delimiting the hollow chamber there (FIG. 3).
  • the lips are provided at a very short distance from the edges 31 of the slot 26.
  • the lips 30, both on their flanks facing away from one another and on their flanks facing one another, which run obliquely towards one another towards the free end of the lip are formed in principle by complementarily shaped grooves 33 on the edges of the cover strip which are delimited on the outside by edge ribs 39 34 overlapped, as can be seen in particular from FIG. 3.
  • the cover strip 34 here essentially has a profile which is turned into the slot 26 and which is not referred to here as a U-profile only to distinguish it from the construction according to FIG. 1.
  • the indentation profile is essentially rectangular, but forms the edge ribs 33 of the cover strip, which form the edge grooves 33, offset somewhat outwards, as can also be seen in FIG. 3.
  • the E instülung has two mutually parallel walls, which are connected to each other by a bottom 36 extending perpendicular to them. The invagination projects through the slot 26 of the plastic profile 20 into the interior of the hollow chamber 24.
  • the wall 28 lying in front of the wall of the metal hollow profile bar 25 with a complementary E instülpung 25a is provided; the outer lateral surfaces of the indentation of the cover strip are guided on the inner side walls of the indentation 25a.
  • the cover strip is clamped against the metal rod 25 with screws indicated only by the arrows 38.
  • the position of the cover strip 34 is relative to the indentation 25 in FIG. 3 in with respect to the possibility of moving up and down clearly fixed.
  • the grooves 33 are tightened over the lips 36, so that here too the edges of the slot 26 are clearly fixed.
  • the cover strip 24 can be tensioned against the metal profile rod 25 by abutting the outer surfaces of the indentation of the cover strip At the outer edges of the indentation of the metal rod 25 achieve that the edge parts of the cover strip 34 forming the grooves 33 move toward one another, which causes an additional reduction in the width of the slot 26.
