In some embodiments of the present invention, a freewheeling lock assembly (10) is provided that includes a housing (14) at least partially defining a cavity (32) and having a central axis, an actuator (30) rotatably coupled to the housing (14) and substantially axially fixed with respect to the housing (14), a lock cylinder (18) received within the cavity (32), having a locked configuration and an unlocked configuration, and rotatable with respect to the housing (14) in both the locked and unlocked configurations, and a clutch having a sleeve (22) and a disk (26) that are received by the cavity (32) and that selectively couple the lock cylinder (18) and the actuator (30) for rotation together in response to rotation of the lock cylinder (18) in one of the locked and unlocked configurations. In some embodiments, the lock cylinder (18) remains substantially axially stationary with respect to the housing (14) when rotated.

L'invention concerne, dans certaines formes de réalisation, un ensemble verrou tournant librement qui comprend un corps définissant au moins partiellement une cavité et présentant un axe central ; un actionneur couplé rotatif au corps et fixé sensiblement dans l'axe par rapport au corps ; un barillet reçu dans la cavité, qui présente une configuration verrouillée et une configuration déverrouillée et peut tourner par rapport au corps dans les deux configurations ; et un mécanisme comportant un manchon et un disque reçus dans la cavité, qui couplent sélectivement le barillet et l'actionneur afin qu'ils tournent ensemble en réponse à la rotation du barillet, dans l'une ou l'autre des configurations. Dans certaines formes de réalisation, le barillet reste sensiblement fixe dans le sens axial par rapport au corps lorsqu'on le tourne.
