Device for attaching threaded plates to support rails

The innovation relates to a device for fastening Ge- _(threaded plates for supporting a mosaic juxtapose -

the components to held in a frame supporting rails which are provided in their longitudinal direction with a T-shaped groove, in particular for fastening of table sections in systems of railway signaling system.

tied together.

The previously required assembly of the threaded plates on the mounting rails was previously carried out as follows: A countersunk screw was inserted from above into a central hole in the threaded plates and provided with a square nut, the edge length of which was adapted to the dimensions of the T-shaped groove of the mounting rails . The crewind plates, together with the countersunk screws and the nuts on them, were placed on the support rails from the side, the nuts being guided through the countersunk screws in the T-shaped groove of the support rails. The threaded plates then had to be pushed to the location on the mounting rails where the table panels were to be attached. The installation location could easily be determined by using appropriate stop gauges; However, it was difficult to bring the threaded plates to the respective installation location, because the nuts guided in the T-shaped grooves of the mounting rails jammed slightly and made it difficult to advance the threaded plates to their installation location due to the clamping effect.

The task of the present innovation is to eliminate this deficiency and also to create a threaded plate, which does not require any separate fastening elements to be attached to the mounting rails.

According to the innovation, this is achieved in that each threaded plate is provided with an insertable into the groove of the support rails ble pin, at the end of which two diagonally opposite, outwardly facing bolts are provided, which after the insertion of the pin into the groove when turning of the threaded plate around the axis c ".ea peg behind the legs of the groove and hold the threaded plate.

The innovation is explained in more detail below using an exemplary embodiment.

Pig. 1 shows a threaded plate according to the invention in three Views and FIG. 2 shows a threaded plate fastened to a mounting rail.

Pig. 1 shows a threaded plate 1 with four concentrically arranged, diagonally opposite thread or thread. Through holes 3 and 5 or 2 and 4. Me threaded plate is on its underside with a in the T-shaped groove of the Support rails insertable pin 6 is provided, the end of which has two diagonally opposite, outwardly facing Bolt 7 and θ, which after insertion of the pin Engage in the groove when turning the threaded plate around the axis of the pin behind the legs of the groove and the threaded plate keep. The bolts 7 and 8 are expediently bevelled towards the outside. When choosing a suitable Material for the mounting rails and the threaded plates, these bars cold the threaded plates as a result of the Turning the threaded plates results in cold deformation of their bevels reaching behind the legs of the groove.

The production of the innovation according to the threaded plates can be done, for example, on a turret lathe, which both the production of the pin and the bolt and the production of the through and threaded holes 2 to 5 allowed.

2 shows a threaded plate 1 fastened to a support rail 9. The threaded plate is attached to the from above Support rail 9 brought up and inserted with its pin 6 into the groove 10 of the support rail, the 'bolts 7 and 8 of the pin 6 in the longitudinal direction of the groove. In contrast to the previously common type of fastening of threaded plates on mounting rails, sliding of the threaded plate on the mounting rail is no longer necessary and therefore jamming or wedging of the pin 6 or the bolt 7 and no longer possible. Is the threaded plate in its place of installation

placed on the mounting rail, it is rotated around the pin 6, the bolts 7 and 8 pivoting outwards, reaching behind the legs of the groove 10 and thus holding the threaded plate 1 on the mounting rail.

To fasten the threaded plate, it is preferably 90 ° relative to its position when inserting the pin 6 into the Turned groove 10. For this purpose, devices can be provided which are provided with pins that can be inserted into bores in the threaded plates and, by means of a stop, a Allow 90 ° rotation of the threaded plate.

When attaching a plurality of threaded plates at a recurring spacing on the mounting rails, it is advantageous to design these devices so that they allow the simultaneous plague turning of several threaded plates of these or adjacent mounting rails.
