Door locking device for motor vehicle doors

The invention relates to a door locking device for motor vehicle doors with a spring-loaded rotatable fork latch that is attached to the door frame with a Catching member cooperates, which engages in a slot of the trap when the door is closed and thereby the trap against the The force of the spring rotates into the locking position, in which it is locked by a locking member.

With compact construction of the lock body and in particular with a relatively large angle of rotation of the latch when locking the door, it is necessary to accommodate a spring acting on the latch Difficult with a suitable spring characteristic, both when the spring is designed as a straight tension spring as well as as a leg spring arranged axially to the pivot of the latch.

The invention is based on the object of arranging a spring acting on the fork latch in such a way that see also at The very compact design of the lock body does not result in any accommodation difficulties.

This is achieved in that with a door locking device the initially specified type of lock body with a is provided substantially arcuate groove, the center of which coincides with the axis of rotation of the rotary latch, and in her a helical compression spring acting as the fork latch against the force of the pang member acting on it when the door is closed

arranged

impacting energy store / Tst, the movable end of which is attached a support surface of the rotary latch, preferably supported on a pin of the rotary latch.

The invention is then described with reference to a preferred embodiment shown in the drawings. They represent:

Fig. 1 is a side view of the door locking device according to the invention, in which the cover plate the door lock removed and the latter is disengaged from the catch member;

FIG. 2 shows a side view of the FIG. 1 corresponding to Door lock, but in the state of engagement of the fork latch in the locking eye;

BAD ORlGlNAL

3 shows a partial section along line III-III in FIG. 2.

In the figures, A denotes a door lock according to the invention, which is attached to a wall C of the door (Fig. 3). B denotes a latching fitting which is attached to a door post D (Fig. 3) and which is in the closed position holds when it interacts with the door lock. The latching fitting B has a base plate B, which is attached to the door jamb D is attached, and a closing eye Bp as a catch member, which with the lock A cooperates.

As shown in Fig. 3, the lock includes a lock body 1 with a base plate 6 and a cover plate ¹ J. It is fastened to a wall C of the door by fastening means, for example screw bolts. The lock body 1 is made of synthetic resin and has recesses la, Ib, lc, Id and Ie. In the recess Id when the door engages the striker bp after passing through slots C, and 7a of the door partition C and the Dskplatte 7 for \ locking the forked latch 2 with the striker _2, a B. The fork latch 2 lies in the recess la, its pin 2a is rotatably mounted in the recess Ie. When the door is closed, one leg of the locking eye Bp engages in a slot 2b of the fork latch 2 and rotates the fork latch into the locking position against the force of a spring acting on the latter. The fork latch 2 acts with rising surfaces 2e and 2f on a rotating locking bolt 3 which is under spring force, the

In the area of the trap is provided with a recess which is delimited by a surface yo extending along a diameter. An axial projection 3c of the locking pin ^ is connected to an end locking lever 8. During the rotary movement of the latch 2, the locking pin 3 lies with its circumferential surface 3a first behind a first latching tooth 2c (when the door is not yet fully closed) and then behind a second latching tooth 2d of the latch 2, which adjoins the slot 2b of the latch, the case being locked against turning back when the door is properly closed.

The spring 5 acting on the latch 2 is a helical compression spring which is mounted in a groove Ic of the lock body 1 having an arcuate part, rests with its front end against an axially parallel support surface of the latch 2 and the latch (in the illustration according to FIG and 2) applied clockwise. The support surface of the trap for the spring 5 is formed by a pin K inserted into the trap.

About such a spring arrangement is against / the arrangement of a

Spring of the same length with a straight spring axis Much more space-saving, so that even with a very compact design of the lock body 1, the accommodation of the spring 5 leash Makes trouble.
