LOCK ASSEMBLY

摘要

A lock assembly (1) comprises: a rotary latch member (3) rotatable between a first, locking, position and a second, released, position; a deadlocking member (4) rotatable between a first, deadlocking, position and a second, released, position; and a cylinder assembly (6) for receiving a key and including a rotary drive element (23) that is arranged to be rotated, upon turning of the key, from a first position in which the rotary latch member (3) is in the first, locking, position to a second position in which the rotary latch member (3) is in the second, released, position. The assembly (1) is arranged such that upon initial rotation of the rotary drive element (23) from the first position towards the second position, the deadlocking member (4) is driven by direct engagement of the rotary drive element from the first, deadlocking, position to the second, released, position.
