The invention relates to a bearing block of Fonnstoff for InstalIatlonsechalter initially snapping of Bettttigungsorgenen as paddles, in particular GroßfiMchenwippen and zrnn Run / on switch cam carriers, for which purpose the bearing Hock with tele resilient pin engages 1n recordings of SchaltnockentrMgers.

And a good height compensation for different plastering depths to ensure, one would like to train the cones long. However, it is difficult, sufficiently resilient cones, which are nevertheless good Provide support, create. On the other hand, there is a risk that metallic pegs that are guided in order to become stable themselves get caught when assembling.

The invention is based on the object of developing a bearing block that enables long resilient pegs that can be easily assembled and yet ensure a good hold in the switch cam carrier. The solution to the problem described is that webs are formed on the bearing block on its frame, which together with the frame form receptacles for a U-shaped bracket made of resilient material and hold it in pockets at the end of the web. The pins on the bar prevent the pins from the bracket and bar from getting caught in the switch cam carrier when they are inserted. You \ j ien the hanger, on the other hand, at its open end and select the hanger area between its back and its off "" n "i" by fixing it at the end.

Can be easily mounted and securely attached to the bridge using a bracket, whom) the frame of the bearing block in the area of the recording partially protruding edge behind that of the U-veneer Clip protruding tabs into place when inserting the bracket.

The bracket is particularly easy to insert into the bearing block, when the U-shaped bracket at its leg ends up to the web thickness cranked together in the receiving area of the bearing block frame is. The bracket is then guided on the bar during insertion.

Ee is favorable if the cross-section of the webs has a T-shaped β profile have, so doθ the bracket when inserting already lateral support finds.

The invention is intended to be based on one in the drawing schematically reproduced exemplary embodiment are explained in more detail:

In Figure 1, a bearing block is shown in side view.

In Figure 2, after a longitudinal section, the bearing block is attached with Large area rocker reproduced. Figure 2 can be used as a section along II-II of Figure 3 are understood. 25th

In Figure 3 is a bearing block with snapped large area rocker shown when viewed from above.

In FIG. 4, a bracket made of resilient material, an individual part of the bearing block, is shown.

Figure 5 shows the bracket according to Figure 4 in side view.

FIG. 6 shows a sectional view of the bearing block in the section along VI-VI according to FIG.

The bearing block according to FIG. 1 has webs 2 molded onto its frame 1. A second web lies behind the plane of the drawing concealed by the re-gegetu * -new bridge. These webs

2 together form kit π em "laluo ^ n 1 creaming 3 -" to compare Figure 6. In the recordings 3, a U-shaped bracket 4 is made of resilient »* Meter * el inserted. The webs form at their web end Pockets 5 that hold the ironing rides. At 6 the admission is a switch cam carrier, which carries the movable switch contact piece, illustrates. Each of the webs 2 and 4 formed Spigots fit into the receptacle 6.

In Figure 2, the bearing block with snapped large-area rocker 7 is shown in section. The rounded end of the web θ facilitates the introduction into the receptacle 6 of the switching cam carrier, which is shown broken off. The U-shaped bracket 4 is bent together at its leg ends 9 up to the web thickness 10 in the receiving area.
15th

The bracket 4 shown in side view in Figure 4 has protruding Flaps 11, which when inserting the bracket behind a projecting edge 12 according to Figure 6 in the area of the recordings 3 click into place. The pockets 5, which receive and hold the temple ends, can also be seen more clearly from FIG.

By means of holes 13 in the legs of the bracket 4, according to FIG. 5, the spring properties of the legs can be influenced.

The T-shaped profile of the webs 2 according to FIG. 2 gives the bracket 4 lateral support when it is inserted. The T-profile can be seen in a section through the web 2, perpendicular to the plane of the drawing in the illustration according to FIG . 2.
