My invention is based on a known device ui * components whose connection wires are in the flfihe of the iindea bent in this way to two oppositely directed bends are that the two identically bent wire parts in two planes perpendicular to the line connecting the free ends, and it is characterized by the fact that the width, Ge: etalt and lung of the opening assigned to each wire in the plate are dug in such a way that · the associated bent wire end · only hindurohgelaaeen after two oppositely directed tilting movements around an axis almost parallel to the line connecting the ends is, and that the bent wire parts are practically completely passed through the plate. As explained in more detail below as a result, it is practically impossible to use the components v. fall out of the plate at the end of the transport.

jSs aei noticed that when mentioned known Device the S-bend of the connection wire is a completely different one The purpose of ftat is to prevent the wires from going too far through the plate wells sink through. The wire parts bent into an S-shape are located outside of the chassis plate and the shape and the Dimensions of the openings must obviously be such that there is the ό-1 'shaped wire parts are not allowed through.

In another known device, the uhüssisplatte consists of three plates placed one on top of the other with holes, whereby three openings are initially aligned. In these the straight wires of the components are inserted into the openings, after which the middle plate is slightly opposite the two muosors

In order to enable the door body to move upwards, this tilting mechanism must be used. Movement to the left can suddenly be converted into a tilting movement to the right (by the angle α in Fig. 2), and it is clear that the forces that are shown on the arrows 11 and 13 during this slow movement Wire 7 act, the ratio can be large. At these points there is a great amount of friction, since the upward movement of the anabolic wire is immediately stopped and in practice the wire does not come further into the dot-dashed position, which, as can be easily seen in FIG. 3, is under Canoe fall back under the action of gravity into the position shown in the drawing.
