Fastener set to connect

Plastic parts, especially plastic

hollow profiles

Fastening element sets for connecting plastic parts are already part of the state of the art They consist of a known embodiment made of lamellar pieces that snap into the corresponding hollow chambers of the hollow profiles to be connected and thereby result in a detachable snap connection, however, it remains unsatisfactory here that the connection does not have the necessary stability. In principle it would of course be possible by means of an additional work step, such as a sticker, “to remedy this” in the However, this would not be in the interest of rational production, which amounts to the greatest possible reduction in work processes. " The task of the present fire is now to create a connection element set that enables a quick, secure and permanent connection of plastic hollow profiles and also compensate for any tolerance inequalities in the hollow profiles.

equals. To solve this problem, a Connection element assumed that consists of a core piece with at least one attached beveled s there is a leg adapted to the inside of the hollow profile »

The characteristic of such a connecting element is now according to the innovation? that the upper fold is provided with a sawtooth-like, knob-like or point-like profile is and that the lower edge of the same or optionally a different leg is a beveled barb-like has curls that when inserted into the hollow profile in a corresponding opening in Hollow profile engages and thereby a fixed and permanent lock between the connecting element and brings about a hollow profile. The new connection element can be designed as a corner piece or dowel plate * Ss can also have openings in a manner known per se, which in the inserted state are under corresponding Openings come to lie in the hollow profile, so that pins are inserted for additional fastening can be.

The! Firing is in the Pig »1 to 6 by means of Three embodiments explained in more detail, Pig.1 shows a perspective view Elbow 1, which is used to produce a corner joint binding of two hollow profiles 2, of which in Fig.1 only one is shown in sections, is used. The elbow 1 Tfe is at right angles to each other standing legs 3 and 4 and parallel to this the legs 5 and 6. The dimensions

the individual legs and the distance between the pair of legs 3 and 4 from the pair of legs 5 and 6 are held so that the legs fit exactly into the hollow chambers of the hollow profile. In order to achieve a quick and permanent connection, the legs are provided with bevels at their ends. "The upper bevel 7 of the leg 3 and the bevel 8 of the leg 4 are provided with sawtooth-like projections 9 and 9 a 5 which serve to compensate for tolerances" instead The sawtooth-like projections shown in the drawing can also be selected a different design in order to compensate for the different failure of the hollow profiles. For example, the arrangement of point or knob-shaped projections should be mentioned »The folds 7 and 8 are further provided with oval openings 1o and 1o a, which come to lie in the hollow profile (2) , in -]? ig »1 but not visible web 12 attached» The lower folds 13 of the legs 5 and 6 are each provided with a beveled cam 14, which allows the angle piece to be pushed into the hollow profile, but into an opening 15 engages in the hollow profile 2, resulting in a mounting support and results in a pulling out of the angle piece prevented from the hollow profile "between the two pairs of legs 3 and 4 and 5 on the one hand and on the other tabs Ίβ are provided. she

serve your privacy _s . so that, for example. "sees no opening with a butt joint.

]? ig "Figure 2 shows a lateral section of the perspective view in" I ¹ Xg. 1 shown 1 elbow connected to the hollow profile 2. It is seen that is snapped into the opening 15 attract the 14th addition, a notch _S cone or Cylinder pin 17 inserted through the superimposed openings 1o and 11 of the angle piece or hollow profile. This, together with the sawtooth-like projections 9, results in a secure and permanent connection between the hollow profile and the angle piece Innovation. It is used to connect front pieces or other materials to the hollow profiles 2 wi . The cover plate has two legs 19 "and 2o to 5, which are arranged parallel one above the other and each again have right-angled bevels. The upper fold of the leg 19 is in turn provided with sawtooth-like projections 22 and an oval opening, the function of which is analogous to that of the comparable ropes from lig.1. In turn, a web 12 is provided parallel to the bevel 21? which is visible in]? ig.4. Furthermore, the lower bevel 24 of the leg, 2.ο, is again equipped with a beveled curl 25 which engages in the opening -15 of the hollow profile 2;

lall is. Finally, with the dowel plate 18 between the two legs 19 and 2o Another tab 26 is provided, it serves as a privacy screen, so that one is blunt Push sees no opening. TJm allow the attachment of other parts to the dowel plate 18 ζτ /, are on the front of the two cylindrical and with a Tiiderhaken-like Toothed dowel (27) vDrgesegeh. The connection between the anchor plate 18 and the hollow profile 2 results from that which is returned in Fig. 4 Sectional drawing, for which everything else that has been said about Hg »2 applies»

Fig. 5 shows another embodiment of the hay, which serves as a corner connection and is intended to connect hollow profiles of unequal size. The corner connection 28 _S shown in FIG. _{the sole 5} connecting as a two-chamber hollow profile 2 with the only single-chamber hollow profile 29 has two legs on the side facing the hollow profile 2 and only one leg on the side facing the hollow profile 29. Otherwise, analogous to the embodiment of FIG. 1, sawtooth-like projections 3o and 31 and oval openings

32 and 33 are provided on the upper leg line lower bevels also in analogy to Mg. 1 and 3 beveled curls 34 and 35 let in, Regarding the connection between lekstück and hollow profiles, which is shown in section in FIG. 6, everything applies analogously to that in Fig «1 and 2 illustrated embodiment said ^
