Abstract:
1. A system for releasably maintaining a movable closure element in a predetermined position relative to a support therefor, the system comprising: a latch assembly to engage a part of a support for a movable closure element on which the system is mounted and having a latched state and an unlatched state; a first actuator assembly having a normal state and a release state, the first actuator assembly and latch assembly operatively interconnected so that the latch assembly is changed from the latched state into the unlatched state as an incident of the first actuator assembly being changed from the normal state into the release state, the first actuator assembly comprising a base assembly and a first handle that is repositionable relative to the base assembly between first and second positions, the first actuator assembly in the normal state with the first handle in the first position and in the release state with the first handle in the second position; and a lock assembly having a locked state and an unlocked state and comprising a locking element that is moved between locked and unlocked positions as the lock assembly is changed between the locked and unlocked states, the lock assembly cooperating with the first actuator assembly and: a) in the locked state the locking element is in the locked position and prevents the first handle from being changed from the first position into the second position; and b) in the unlocked state the locking element is in the unlocked position and allows the first handle to be changed from the first position into the second position, the lock assembly comprising a motor that is actuatable to move the locking element and thereby change the lock assembly between the locked and unlocked states, the lock assembly further comprising a manual actuator subassembly that is operable to move the locking element between the locked and unlocked positions to change the lock assembly between the locked and unlocked states, wherein the locking element is part of a lock cam that is movable around an axis as the locking element is changed between the locked position and the unlocked position.
