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.
Claims21
-17. (canceled)
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.
A lock comprising:
- a housing;
- a deadbolt disposed within the housing, wherein the deadbolt is linearly movable between a retracted position wherein the deadbolt is fully retracted within the housing and an extended position wherein the deadbolt at least partially extends from the housing;
- a rotatable deadbolt actuator connected to the deadbolt;
- a drive element movably engaged with the deadbolt;
- a first pawl disposed on a first side of the deadbolt, wherein the first pawl is pivotably engaged with the housing and movably engaged with the drive element;
- and
- a second pawl disposed on a second side of the deadbolt, wherein the second pawl is pivotably engaged with the housing and movably engaged with the drive element.
A lock comprising:
- a housing;
- a deadbolt slidably disposed along a first axis within the housing;
- a drive element slidably disposed along a second axis orthogonal to the first axis within the housing, wherein the drive element is engaged with the deadbolt;
- a first pawl pivotably connected to the housing and movably engaged with the drive element;
- a second pawl pivotably connected to the housing and movably engaged with the drive element;
- and
- an actuator pivotably engaged with the housing and engaged with the deadbolt such that a pivotal movement of the actuator moves the deadbolt along the first axis.
