A LOCK

摘要

A lock for locking a door, the lock comprises a pin moveable between a retracted position and an extended position for locking the door and an actuator movable from a first position to a second position to move the pin from the retracted position to the extended position. Furthermore, the lock comprises a mechanism comprising a spring for biasing the pin to the retracted position and a latch. When in the latched position the latch prevents the pin from moving from the extended position to the retracted position, and when in an unlatched position the latch allows the pin to move from the extended position to the retracted position. The mechanism is adapted to disengage the actuator from the pin when the pin is in the extended position.
