Abstract

The aim of the invention is to design a door lock or flap lock which can be easily and reliably opened with little effort. Said aim is achieved by a door lock or flap lock comprising a locking mechanism that consists of a latch and at least one pawl for locking the latch. The lock further comprises a triggering lever which, upon being actuated, allows the locked locking mechanism to be unlocked. The lock also comprises a spring for moving the pawl in the direction of the locking position. The triggering lever is designed in such a way that the actuation thereof at least reduces, preferably altogether cancels the spring force acting on the pawl, i.e., when the triggering lever is actuated, the spring force that presses the pawl in the direction of the locking position decreases at least. Since such a force makes it difficult to unlock a locking mechanism, actuating the triggering lever at least reduces or altogether does away with said difficulty when the spring force is canceled entirely. As a result of the fact that the triggering lever has two functions, the number of parts can be kept to a minimum Advantageously, the lock therefore is not complex to produce and is compact and lightweight.

Claims

1. A lock for a door or flap comprising a locking mechanism that comprises a rotary latch and at least one pawl for locking the rotary latch and a spring for moving the pawl in the direction of its locking position and a triggering lever for unlocking the locking mechanism by actuation of the triggering lever, wherein the triggering lever is designed in such a way that its actuation reduces or cancels out the force of the spring acting on the pawl.

2. The lock according to claim 1, wherein the pawl and the triggering lever are rotatably mounted on a common axis.

3. The lock according to claim 1, wherein the spring can rest against a lever arm of the pawl for moving the pawl in the direction of the locking position and/or against a lever arm of the triggering lever to reduce or cancel out the spring force acting on the pawl.

4. The lock according to claim 1, wherein the lever arm of the pawl as described in the above claim, and the lever arm of the triggering lever, as described in the above claim, are arranged above each other in the locked state of the locking mechanism.

5. The lock according to claim 1, wherein the rotary latch can initiate an opening moment in the pawl in order to move the pawl out of its locked position.

6. The lock according to claim 1, comprising a tappet, that can also move the pawl out of its locking position and, in particular, after a delay.

7. The lock according to claim 1, comprising a blocking lever, able to block the pawl in its locking position.

8. The lock according to claim 7, wherein the triggering lever can move the blocking lever out of its blocking position.

9. The lock according to claim 7, comprising a spring for moving the blocking lever into its blocking position.

10. The lock according to claim 1, comprising a spring for moving the rotary latch into its opening position.

11. The lock according to claim 1, wherein the triggering lever contains three lever arms.

12. The lock according to claim 1, wherein the pawl contains two lever arms.

13. The lock according to claim 1, comprising a blocking lever with two lever arms.
