Stop in particular for the slide block in a guide track

A stop is disclosed which can be mounted without a great work effort, permits setting in any position and simple adjustment, and whose firm seating is guaranteed. The stop is displaceable in a guide rail having a C-shaped cross section and is preferably served to limit the travel of a sliding piece connected to the window pane of a motor vehicle. It is designed as a spring clip, it can be pushed into the rail having a C-shaped cross section, it can be displaced and fixed in same, and it absorbs a high impact force. The spring clip is bent in a wave-shaped pattern and has claws for fixation inside the said rail having a C-shaped cross section.

The present invention pertains to a stop, especially for a sliding piece 
which is movable in a guide rail having a C-shaped cross section and is 
connected to the window plane of a motor vehicle. 
A sliding place for guiding window panes, especially of motor vehicles, 
which is arranged in a guide rail, is disclosed in DE-PS No. 35 03 547. 
The said sliding piece is pushed into the said rail having a C-shaped 
cross section through a recess provided at the top end of the guide rail. 
A stop fixed by screws in the said rail having a C-shaped cross section 
prevents the undesirable exit of the said sliding piece located in the 
said rail having a C-shaped cross section into the said recess at the top 
end of the said guide rail. The prior-art stop requires cumbersome 
mounting, because it must be fixed with screws. No provision is made for 
continuous adjustment of the said stop. 
The task of the present invention is therefore to create a stop which can 
be mounted without great work effort, permits setting in any desired 
position, and simple adjustment, and in which firm seating is guaranteed. 
This is achieved according to the present invention in an advantageous 
manner in that the said stop is designed as a spring clip, it can be 
pushed into the said rail having a C-shaped cross section, it can be 
displaced and fixed in the said rail, and it absorbs a high impact force. 
According to an advantageous further improvement of the present invention, 
the said spring clip is bent in a wave-shaped pattern and is symmetrical. 
The spring clip has claws with which it can be fixed inside the said rail 
having a C-shaped cross section. Furthermore, the said spring clip may 
also have two legs reaching out of the said rail having a C-shaped cross 
section, which said legs bring about the release of the said claws on 
compression to permit displacement of the spring clip in the longitudinal 
direction of the said rail having a C-shaped cross section. The 
tongue-like claws can be formed by incisions made in the spring plate and 
by bending over. The said claws may be arranged in openings of the said 
spring clip and at the two legs of the said spring clip The said spring 
clip can be inserted into and released in the said rail having a C-shaped 
cross section by means of round-nosed pliers bent at right angles with 
which the said legs reaching out can be pressed together. The said legs of 
the said spring clip may also be flat instead of being curved and may be 
provided with holes for bent round-nosed pliers. 
The said stop according to the present invention can be manufactured simply 
and inexpensively as a stamping part, so that economical mass production 
is possible. It is also characterized by easy and rapid mounting in the 
corresponding rail having a C-shaped cross section, and it can easily be 
released from its locked position and adjusted by means of the said two 
legs reaching out of the said rail.

The symmetrical spring clip 1 is made from a spring plate, bent in the 
shape of a wave and adjusted to the inside dimensions of the rail 2 having 
a C-shaped cross section. As is seen in FIG. 2, the spring clip 1 has the 
shape of two U-shaped parts 3 and 4 which are connected to each other and 
form the stop faces, and it has upwardly directed, tongue-like claws 5 
through 8 on each side, which said claws sink into the material of the 
said rail 2 and bring about firm seating of the said spring clip 1 in the 
said rail 2. The two legs 15 and 16 of the said rail 2 having a U-shaped 
cross section have inwardly bent parts 17 and 18. The tongue-like claws 5 
through 8 are formed by incisions made in the spring plate and by bending 
up. The claws 6 and 7 intended for the bent parts 17 and 18 are located in 
openings 19 and 20 of the said spring clip 1. The said spring clip 1 has 
two legs 22 and 23 at which the said claws 5 and 8 are disposed, and which 
reach out of the slot 24 between the two bent parts 17 and 18 of the said 
rail 1. When the two legs 22 and 23 are compressed by means of round-nosed 
pliers bent at right angles, the said claws 5 through 8 separate from the 
rail 2 having a C-shaped cross section, and the stop formed by the said 
spring clip 1 can be removed from or displaced in the said rail 2 until 
the said spring clip 1 springs back and is fixed in its new position upon 
releasing the legs 22 and 23. 
The said claws 5 and 8 are also sufficient for anchoring the said stop, but 
the plate must be thicker in this case. 
The design of the spring clip 1 as shown in FIG. 4 differs from that shown 
in FIG. 1 by the different shape of the legs. While the legs 22 and 23 are 
curved to enable their being compressed by means of round-nosed pliers 
bent at right angles, the legs 26 and 27 are flat and have holes 28 and 29 
in them for inserting bent round-nosed pliers. 
Although the illustrated embodiment(s) thereof (hereof have) has been 
described in great detail, it should be apparent that certain 
modifications, changes and adaptations may be made in the illustrated 
embodiment(s), and that it is intended to cover all such modifications, 
changes and adaptations which come within the spirit of the present 
invention.
