Di ^ vo ^ lies-endp Lieuerun'r concerns a ^ n metal parts or Stamped parts set with connecting device.

"It is known to design the connection device in such a set of parts as a rivet connection, in the coupling points or doT-like projections in a corresponding opening in the other part through which one part races through _we ^m Eils riveted x ^ ground.

the task of the present innovation is to nern - = »| _n p-an °: s named Teiteatz, the connection

Addition of material, clean connection points are available. The solution This task is characterized according to the innovation by at least ^ ine Kup-Dlungszunge on a first part, which in a recess Jan intervenes in a second part of the sentence, wo'oei the side Walls of the coupling tongue and the recess in the

junction show interlocking bumps. This connecting device To a certain extent represents an internal riveting

idar. So only inside, so / invisible surfaces, one Deformation of the material is present, the connection points remain

len outside very clean.

The following is the innovation based on two exemplary embodiments explained in more detail.

; Figures 1 and 2 show a first embodiment in section,

I ^w

namely Fig.1 before and Fig.2 after the connection, so in the finished State. Fig. 3 shows another embodiment, graphically, before the connection.

According to FIG. 1, the Teiteatz has parts 1 and 2. Part 1 is provided with a coupling tongue 3, while the part 2 with a continuous slot 4- is provided. The width of the slot 4 corresponds to the thickness of the part 1 or the tongue 3 The length of the slot 4- corresponds to the width of a head part 5 of the tongue 3. Recesses close on both sides of this head part 5 6 with cylindrical boundary surfaces. The base odei *

The base part 7 of the coupling tongue 3 is wider on the outside the head part 5 and its width also exceeds the length of the slot 4- in the vertical part 2. The edges between the boundary surfaces 6 and the side walls 8 of the foot part 7 each form one sharp cutting edge 9 the purpose of which is explained below.

To connect the parts 1 and 2, the coupling tongue 3 is inserted into the slot 4, which can easily happen until the two cut edges 9 strike the top of the part 2. If the coupling tongue 3 is now further into the slot i
driven in, so cut the two. Cut edges at the edges 10 of the part 2 material away, which material penetrates into the recesses 6. After the coupling tongue 3 has been completely driven in, the situation according to Pig.2 arises, ie the material cut away at the sides of the edges 10 has practically completely filled the recesses 6, so that the tongue 3 is now also rigidly connected to the part 2. Versii.che have found that the connection created with it can withstand very high loads. The connection is also very clean seen from the outside, in that the end face 11 of the coupling tongue 3 closes the visible opening of the slot 4-flush after the connection of the parts.

While in Fig.i and 2 a single connection point with a coupling tongue 3 is shown, can of course Lich the stamped parts 2 and 1 by several similar connection points be connected.
