Abstract
A lock includes a deadbolt assembly having a deadbolt and a deadbolt actuator. The lock also includes a latch assembly discrete from the deadbolt assembly. The latch assembly includes a shoot bolt and a shoot bolt actuator. A blocking element may block actuation of the shoot bolt from an unlocked position to a locked position when the deadbolt is in a retracted position. Alternatively or additionally, the blocking element may block actuation of the shoot bolt from a locked position to an unlocked position when the deadbolt is in an extended position.
Claims15
A lock comprising:
- a deadbolt assembly disposed in a deadbolt assembly housing and comprising a deadbolt retractably disposed in the deadbolt assembly housing and a deadbolt actuator;
- a latch assembly disposed in a latch assembly housing discrete from the deadbolt assembly housing, the latch assembly comprising a latch retractably disposed in the latch assembly housing, a shoot bolt, and a shoot bolt actuator, wherein the shoot bolt extends from the latch assembly housing and is slidably engaged with a portion of the deadbolt assembly housing;
- and
- a blocking element disposed in the deadbolt assembly housing and adapted to extend into a path of travel of the shoot bolt so as to block at least one of (a) actuation of the shoot bolt from a first position to a second position when the deadbolt is in a retracted position, and (b) actuation of the shoot bolt from a second position to a first position when the deadbolt is in an extended position.
A lock comprising:
- a deadbolt housing;
- a deadbolt retractably disposed in the deadbolt housing;
- a deadbolt actuator for actuating the deadbolt;
- a shoot bolt selectively moveable between a second position and a first position, wherein the shoot bolt is actuated remote from the deadbolt housing, and wherein the shoot bolt is slidably engaged with a portion of the deadbolt housing;
- a pawl located in the deadbolt housing, wherein the pawl is adapted to extend into a path of travel of the shoot bolt so as to block movement of the shoot bolt from at least one of (a) the first position to the second position, and (b) the second position to the first position;
- a latch housing discrete from the deadbolt housing;
- and
- a latch assembly located within the latch housing, the latch assembly comprising a shoot bolt actuator for moving the shoot bolt from the second position to the first position.
