Abstract
There is disclosed a dead-latching slam bolt lock that includes a rotating dead-latching slam bolt which prevents attempts at breaking in without actuating the lock mechanism. A tongue or toggle acted on by the door jamb engages the bolt and initiates rotation thereof in the door closing direction, but is passive in the opening direction. The locking mechanism may be manual or electronic, and controls the position of a blocking element which alternately prevents and permits unlocking (rotation) of the rotating bolt. In a forward or blocking position, the blocking element prevents rotation of the bolt from a locked position, while in a retracted position the blocking element permits rotation of the bolt to an unlocked position. A spring detent plunger holds the rotating bolt in either its locked or unlocked positions.
