Abstract
A lock assembly (20) including a lock bolt (28), a first hub (36) and a first hub locker (72). 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 first hub locker (72) is positionable in at least three positions. The first hub locker (72) allows movement of the lock bolt (28) in response to torque being applied to the first handle when in two of the at least three positions and prevents movement of the lock bolt in response to torque being applied to the first handle when in another of the at least three positions. Alternatively, the first hub locker (72) prevents movement of the lock bolt (28) in response to torque being applied to the first handle when in two of the at least three positions and allows movement of the lock bolt (28) in response to torque being applied to the first handle when in another of the at least three positions.
