Lock for a flap or door
First Claim
1. A lock for a door or flap comprising:
- a locking mechanism having a locked state and an unlocked state, the locking mechanism comprising;
a rotary latch;
at least one pawl for locking the rotary latch, the pawl being pivotable between a locking position in which the pawl acts against the rotary latch and an unlocking position in which the pawl disengages from the rotary latch;
a spring that rests against the pawl to bias the pawl in the locking position; and
a triggering lever that is pivotable to rest against the spring and push the spring away from the pawl enabling the rotary latch to initiate a torque into the pawl to pivot the pawl toward the unlocking position for moving the locking mechanism from the locked state to the unlocked state.

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. When the triggering lever is actuated, the triggering lever rests against the spring to push the spring away from the pawl and decrease or cancel the spring force. Using the triggering lever, 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.
