DE2333060A1 - Tumble lock for car doors - has latch trap over clip spring to ensure closing of locking pin - Google Patents

Abstract

The arrangement of a revolving tumble lock has a latch trap to which is attached a clip spring to ensure that the closed door locks safely over the locking pin on the door frame without the latter having a counter latch. The spring is shaped as a narrow U-section dipped onto the lock framework and with one of its arms pressing resiliently upward against a disc revolvable with the latch, and having a flat engaging with the spring in the locked position.

Arrangement with a rotary latch lock on a door or flap of a vehicle

The invention relates to an arrangement with a rotary latch lock on a door or flap of a vehicle with a rotary latch that engages around a locking pin attached to the door post when the door is closed, as well as with a at least at one end bent support bearing, which with its turning cooperates via a buffer with a counter bearing located on the door post and when it is closed Door ensures a backlash-free fit of the door in the area of the rotary latch lock.

Such an arrangement is already known from German Auslegeschrift 1 553 299, Kl-68a, 91. That is what it consists of Support bearing made of a C-shaped retaining plate attached to the front of the door, the upper leg of which is inclined

when closing the door under the also with a bevel provided buffer runs, which is attached to a on the door

Post located lock bolt is attached. Due to the wedge-shaped design of the buffer and the one Stützla-. gerschenkels, the door is centered in its opening during the closing process and kept practically free of play.

The invention is based on the object of this known arrangement to simplify significantly without affecting their operational safety.

The invention solving this problem consists in the fact that the bend is on the side of the locking pin facing away from the rotary latch lies, carries the buffer and the locking pin forms the counter bearing. An essential achieved by the invention The advantage is that you no longer need a counter bearing specifically required for this purpose. but an already existing rope, namely the locking pin, can take over the function of the counter-bearing. In order to associated is a considerable saving in material, because the locking bolt is essential in the known design can be kept smaller or omitted entirely; the locking pin only needs to be attached to the door post.

According to a further embodiment of the invention, a substantially U-shaped spring clip with inwardly bent leg ends are used, which over the buffer and the bend of the Support bearing is pushed, wherein the leg ends engage behind the buffer and the support bearing. The suitably metallic The spring clip not only has the function of attaching the buffer to the support bearing, it also falls at the same time the task of reducing the wear and tear of the rubber or plastic buffer as a result of friction during the closing process to prevent.

Advantageously, the TJ-shaped spring clip is on her The base is provided with a stop that limits the displacement path of the spring clip in the direction of the buffer. Iir such a measure you can provide the spring clip at its base with a relatively large bending radius, * what the production of the spring clip is made much easier and the local stress on the spring clip is reduced; on the other hand, the stop prevents the spring clip from opening during the closing process would be pushed further over the buffer, causing excessive stress and breaking in the area of their base would. For reasons of space, it will usually be useful that the stop between the legs of the U-shaped spring clip and is worked out directly from the base of the spring clip.

An embodiment of the invention is explained in more detail with reference to the drawing.

FIG. 1 shows a longitudinal section through an embodiment inventive arrangement with the door closed.

Figure 2 shows an end view, partially in section, of the arrangement shown in Figure 1, namely according to the section line II-II in Figure 1 on an enlarged scale.

1 with a holding plate for the locking pin 2 is referred to, which is mostly on the door post, not shown here is attached. On the other hand, the actual rotary latch lock sits on the door, its most essential components the fork-shaped rotary latch 3 and on a base

plate 4 fixed support bearings 5 are. The rotary latch 3 is mounted in a common bore in the base plate 4 ¹¹¹¹ CL support bearing 5 with the aid of a bush 6 and secured against axial movements by a Met 7. On the back of the base plate there is also a locking disk 8, which is non-rotatably connected to the rotary latch, but has no further significance for the present invention. The support bearing 5 has a bend 9 at its lower end, which in this exemplary embodiment is U-shaped, although this is not absolutely necessary because, for example, only a right-angled bend could serve the same purpose. An elastic buffer 11 is attached to the bend 9 by means of an approximately U-shaped spring clip 10.

As can be seen more clearly from Figure 2, the spring clip 10 with the wedge-shaped buffer 11 is laterally on the Turn 9 <les support bearing pushed until the one after inside bent leg end 12 of the spring clip 10 the Support bearing engages behind. The other free leg end 13 the spring clip 10 is also bent inwards and thus prevents the buffer 11 from slipping out to the left. On the right-hand side, the buffer is also held by the geometric adaptation of the spring clip to the buffer.

At its base I4, which is designed in the shape of an arc of a circle, the Spring clip 10 has a stop I5, which the displacement the spring clip on the bend of the support bearing 5 is limited. As can be seen from Figure 1, this stop is 15 between the legs egg "spring clip 10 and is worked out directly from Basis I4.
