Lock for closing and/or locking door of building, has locking mechanism designed such that minimum spring force is applied to pivot lock pawl from detent position by rotary latch, and lever blocking lock pawl in rusty state of mechanism

摘要

The lock (1) has a lock pawl (3) rusting a rotary latch (2) of a locking mechanism. A blockade lever (4) blocks the lock pawl in a rusty state of the locking mechanism, where the rotary latch and the lock pawl are designed such that the rotary latch is able to pivot the lock pawl from a locked position when the lock pawl is not blocked by the blockade lever. The locking mechanism is designed such that minimum spring force is applied to pivot the lock pawl from the detent position by the rotary latch.
