The bolt of a bolt housing according to the invention can be used as a dead bolt.
The bolt can also be used to ensure that the dead bolt remains operable.
The invention also relates to a method for mounting a bolt housing comprising a dead bolt.
A lockset for a door in which the latch bolt assembly includes a bolt (12) movable between a partially extended latching position, a fully extended dead bolt position, and a retracted position.
The bolt (12) automatically extends into its dead bolt position when the door is closed by means of a latch release plunger (192).
The actuator (38) is connected between a deadbolt arm (70) in the mortise lock, which drives the deadbolt (20), and the hook bolt latch mechanisms (22, 24).
A lock includes a deadbolt assembly having a deadbolt and a deadbolt actuator.
The lock also includes a deadbolt mechanism for placing the lock in a deadbolt condition.
Another sensing system senses the position of the bolt and/or a dead-latch bar (1310).
The lock (1) is configurable as either nominally locked or nominally unlocked and is deadbolted when the bolt (3) is extended beyond a certain extent and not deadbolted otherwise.
A deadbolt mechanism including a lock out mechanism that functions to disable the operation of the deadbolt from at least one side of the deadbolt mechanism.
The locking bolt (15) may be a slam bolt having a spring (50) biased latch (16) which slides therewith or the locking bolt (15) may be a deadbolt when the lock is used with a boltwork system of a vault door.
The deadbolting means of the lock according to the invention comprise a locking piece (15) to establish and release the locking of the deadbolting means in the deadboltingposition.
A sensing system senses whether or not a lock's bolt (140), e.g. deadbolt, is aligned with a hole (150) which the bolt is to engage in the locked state.
The deadlock member (60) is moveable relative to the bolt (40) to engage surrounding structure (34) and thereby resist movement of the bolt (40) from the deployed configuration.
The latch bolt assembly is used for triggering a deadbolt (21), is reliable during the trigger process, and completely avoids the phenomenon that the deadbolt (21) collides with other parts.
The state dead-bolt is sensed.
A lock mechanism includes a lock bolt mechanism (6), for instance a key actuated mechanism, having a lock bolt (20a) and a latch bolt mechanism (4) including a latch bolt (9) and actuated by a follower lever (17).
