Abstract

In an exemplary embodiment, a door lock includes a locking latch which is rotatable to and fro between a locking position and an unlocking position; a locking holder that engages the locking latch in a locking position; and a stop that limits the rotational movement of the locking latch; wherein the stop is repositionable and provides different stop positions in different stop receptacles.

Claims (19)

1. A door lock, comprising:

a locking latch;

a locking holder, wherein the locking latch is rotatable relative to the locking holder between a locking position and an unlocking position, wherein the locking holder is configured to engage the locking latch when the locking latch is in the locking position to form a locking engagement therebetween; and

a stop that is configured to engage the locking latch at a stop position to limit rotational movement of the locking latch, wherein the stop is positionable in different stop receptacle to provide different stop positions, and wherein the stop receptacles are arranged on the locking holder.

2. The lock of claim 1 , wherein the stop is repositionable from one stop receptacle into another stop receptacle.

3. The lock of claim 1 , wherein the locking latch has two latch elements, and wherein the door lock is configured such that either of the two latch elements is engageable by the locking latch to form the locking engagement between the locking latch and the locking holder.

4. The lock of claim 3 , wherein the lock is configured such that one of the two latch elements is engaged by the locking holder to lock the door while the other latch element strikes against the stop to limit the rotational movement of the locking latch.

5. The lock of claim 1 , wherein the locking latch is rotatably mounted in a latch housing.

6. The lock as claimed in claim 1 , wherein the stop receptacles are configured as insertion openings into which the stop is selectively insertable.

7. The lock of claim 1 , wherein the stop includes a locking stop surface for limiting a rotational movement of the locking latch in the locking direction and an unlocking stop surface for limiting the rotational movement of the locking latch in the unlocking direction.

8. The lock as claimed in claim 1 , wherein the locking holder includes a mounting element in which the locking holder is fastenable to a door frame in a mounting plane, a holding element, and a holding surface which is arranged at a distance from the mounting plane and which can be engaged behind by the locking latch to lock the door.

9. The lock as claimed in claim 8 , wherein each stop receptacle includes a recess extending into the holding element and/or into the mounting element.

10. The lock of claim 9 , wherein the stop includes a guide element that is guided in the recess.

11. The lock of claim 1 , wherein the stop is connectable to the locking holder via a holding shoe that is pushable onto a holding element of the locking holder.

12. The lock as claimed in claim 11 , wherein the holding shoe holds a guide element of the stop in the associated stop receptacle.

13. A door, comprising:

a lock having a locking latch;

a locking holder, wherein the locking latch is rotatable relative to the locking holder between a locking position and an unlocking position, wherein the locking holder is configured to engage the locking latch when the locking latch is in a locking position; and

a stop that is configured to engage the locking latch at a stop position to limit the rotational movement of the locking latch, wherein the stop is positionable in different stop receptacles to provide different stop positions, and wherein the stop receptacles are arranged on the locking holder.
