Description

GERMAN

The invention relates to a door lock for vehicles, the latch bolt in the closed position is blocked by a pawl which, when the bolt is withdrawn by means of the separately arranged Outside or inside handle is lifted. The lock is self-closing, i.e. H. its under Effect of the spring bolt latch is in the closed position when the door is open, it is closed when it slams the door pushed back against the action of its spring, with the pre-pressed by a spring The pawl engages and the latch locks.

With the locks of vehicles, especially the fast moving vehicles, a safe one is Locking closed doors is of the utmost importance. With these. Doors that make a rattle Avoiding the need to lie in the door frame free of play when driving is a particular danger great that the latch does not get into its full Sch'Heßlage when closing or slamming the door.

The known door locks can only secure the bolt latch when it is in the fully closed position stands, the bolt in the front or safety catch remains unsecured.

To eliminate this deficiency is according to the invention the locking device of the lock blocking the bolt in the closed position, double-acting designed, a pawl blocks the latch in the fully closed position and in its pre-closing position. The latch bolt odfer also their blocking device have two of the two closed positions of the Latch catches corresponding notches, which block them in both positions and also when not in proper order Secure the lock of the door in the closed position. For this; is the pawl of one in the closed position through the strike plate in the everted and in the open position from the pull-out release latch can be controlled in a non-positive manner, whereby in the offendage the The latch releases.

This double securing of the lock bolt can be used for locks of different types, so z. B. with the most common vehicle door locks with bolt latch, as well as with the door locks, in which a guide pin is built into the lock, which is in one with two notches provided pin housing engages the door frame.

The drawing represents the application of the invention in a conventional bolt latch lock and in a Mortise lock in exemplary designs.

^a 5, the latch 1 is constantly pressed into the closed position by the spring 2, it is to be withdrawn by the nut arm 3 of the outer handle nut 4 and through the nut arm 5 of the inner handle nut 6. The latch has two notches 7 and 8, in which the locking hook 10, which is pivotably mounted on the bolt 9, can engage. The notch 7 corresponds to the fully closed position of the bolt latch, the notch 8 corresponds to its position in the front or security notch of the locking bolt that is fixed on the door frame. In both cases the.

after the door has been slammed, the latch bolt that has come forward is blocked by the locking hook 10 (Fig. 1 and 2).

To lift the locking hook out of the catches of the latch bolt, move the outside handle and the Inside handle follower when it rotates with arms 11 and 12 a slide 13, which the locking hook 10 pulls out of the catches of the bolt latch. Here, the locking hook 10 acts via a spring 14 on the Release slide 15, which under the action of the spring 16 stands, which is constantly striving to close the slide move that its abutment end protrudes from the lock faceplate 17 (Fig. 3). When the door slammed the latch 1 and the release slide 15 by their impact on the locking bolt or strike plate of the Pushed back the door frame, the tensioned spring 14 of the slide 15 pushes the The locking lug of the locking hook 10 against the sliding surface of the lock latch located in front of the notches 7 and 8, so that the locking hook when the

The latch catches in one of the two notches 7 and 8 and blocks the latch.

Those of the closing and pre-emptying positions Latch latch corresponding notches can also, instead of on the latch latch with the same effect on the Locking hook 10 lie.

The latter arrangement of the double notches is in the case of the bolt lock according to, Fig. 4 to 6 realized. The engaging in the fixed on the door frame housing for the lock pin 18 Latch 19 has the blocking of the bolt in its closed position and its pre-locked position serving approach 20, which in the notch of the pivotably mounted on the bolt 21 locking lever 22 engages or bumps against the head end.

The notch and the head end of the locking lever 22 correspond to the two possible closed positions the latch 19, which it occupies when it is in the fully closed position or in the safety catch stands. In this lock, the latch bolt in the open position is not closer by one in dfer drawing shown locking rail 23 held (Fig. 6), which is pushed back when the door is slammed and the latch 19 for engagement with the lock housing of the door frame releases. When opening the Door by means of the outside handle 24 or the inside handle 25 is the locking lever by a with the Nut arm 26 of the outside handle or the nut arm 27 of the inside handle cooperating lever mechanism withdrawn from its blocked position. So that the locking lever 22 does not interfere with the latch 19 can, something is wrong.
