Abstract
An electronic deadbolt lock arrangement including a lock having a bolt movable between locked and unlocked conditions. The lock includes a manual control and a power drive to operate the lock that are connected by a decouplable transmission enabling the lock to be operated by either the manual control or the power drive. The transmission includes two concentric cylinders that can be locked or unlocked for relative rotational movement, with manual operation of the lock decoupling the power drive. A biased pin engages co-operating apertures in the cylinders to lock the two cylinders to each other. A cam operated by the manual drive acts against the pin to cause the two cylinders to be decoupled.

An electronic deadbolt lock arrangement including:
- a lock having a bolt movable between locked and unlocked conditions, the lock having a manual control means serving to operate the lock between said locked and unlocked conditions:
- a power drive coupled by a transmission to the manual control means whereby the lock is operated between the locked and unlocked conditions in response to operation of the power drive;
- a transmission means coupling the manual control means and the power drive whereby the lock moves between said locked and unlocked conditions;
- the transmission means operable to decouple the power drive from the manual control means to enable the lock to be operated by the manual control means independently of the power drive, said transmission means includes an inner and outer concentric rotatable cylinders, the two cylinders are biased into a coupled position by biasing means and are decoupled by a centrally located cam acting on a pin engaging mechanism urging a pin out of engagement with at least one cylinder to thereby decouple the cylinders.
