<p>An electronic deadbolt lock arrangement including a lock having a bolt movable between locked and unlocked conditions. The lock includes a manual control means 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 means 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 means acts against the pin to cause the two cylinders to be decoupled.</p> |
