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.
Claims20
A lock comprising:
- a deadbolt assembly comprising a deadbolt and a deadbolt actuator;
- a latch assembly discrete from the deadbolt assembly, the latch assembly comprising a shoot bolt and a shoot bolt actuator;
- and
- a blocking element for blocking at least one of (a) actuation of the shoot bolt from an unlocked position to a locked position when the deadbolt is in a retracted position, and (b) actuation of the shoot bolt from a locked position to an unlocked position when the deadbolt is in an extended position.
A lock comprising:
- a deadbolt housing;
- a deadbolt located within the deadbolt housing;
- a deadbolt actuator for actuating the deadbolt;
- a shoot bolt selectively moveable between a locked position and an unlocked position, wherein the shoot bolt is actuated remote from the deadbolt housing;
- and
- a pawl located in the deadbolt housing, wherein the pawl blocks movement of the shoot bolt from at least one of (a) the unlocked position to the locked position, and (b) the locked position to the unlocked position.
A method of actuating a multi-point lock, the method comprising:
- extending a first locking element using a first actuation element;
- and
- thereafter, extending a second locking element using a second actuation element, wherein the second locking element is extendable only by first extending the first locking element.
