Lock assembly

摘要

An electrically controllable lock assembly (20) including a lock bolt (28), a first hub (36), a second hub (68), a first hub locker (64), a second hub locker (72), a first driver (62) and a second driver (70). The lock bolt (28) is movable between a latching position and an unlatching position. The first hub (36) is adapted to move the lock bolt (28) in response to movement of a first handle. The second hub (68) is adapted to move the lock bolt (28) in response to movement of a second handle. The first hub locker (64) is positionable to selectively prevent or allow movement of the lock bolt (28) in response to torque being applied to the first hub (36) from the first handle. The second hub locker (72) is positionable to selectively prevent or allow movement of the lock bolt (28) in response to torque being applied to the second hub (68) from the second handle. The first driver (62) is electrically controllable to position the first hub locker (64) to thereby selectively prevent or allow movement of the lock bolt (28) in response to torque being applied to the first hub (36) from the first handle and the second driver (70) is electrically controllable to position the second hub locker (72) to thereby selectively prevent or allow movement of the lock bolt (28) in response to torque being applied to the second hub (68) from the second handle.

1. An electrically controllable lock assembly including:
a lock bolt movable between a latching position and an unlatching position; a first hub adapted to move the lock bolt in response to movement of a first handle; a second hub adapted to move the lock bolt in response to movement of a second handle; a first hub locker positionable to selectively prevent or allow movement of the lock bolt in response to torque being applied to the first hub from the first handle; a second hub locker positionable to selectively prevent or allow movement of the lock bolt in response to torque being applied to the second hub from the second handle; a first driver electrically controllable to position the first hub locker to thereby selectively prevent or allow movement of the lock bolt in response to torque being applied to the first hub from the first handle; and a second driver electrically controllable to position the second hub locker to thereby selectively prevent or allow movement of the lock bolt in response to torque being applied to the second hub from the second handle, wherein the first hub locker and the first driver are settable as either fail safe—or fail secure and the second hub locker and the second driver are settable as either fail safe or fail secure, and wherein the fail setting of the first hub locker and the first driver and the fail setting of the second hub locker and the second driver are independent of one another.
