Abstract
A lock assembly for a door includes a lock body for mounting above a door lever of the door and including a locking bolt supported in a housing of the lock body for movement between a retracted position and an extended position. The locking bolt is held in the retracted position and spring biased toward the extended position and releasable from the retracted position to move to the extended position in response to actuation of a trigger operatively coupled with the lock body. The lock assembly further includes a door lever assembly adapted for mounting on the door lever in rotative fixed relationship with the door lever, and operatively coupled with the locking bolt so that rotation of the door lever assembly causes movement of the locking bolt from the extended position to the retracted position.
