Patent ID: 7353673

Claim:
A locking device utilizing a key, comprising: a stationary plug having a first aperture extending therein configured to receive the key, the stationary plug further comprising an outer surface, an inner surface defined by the first aperture, and a plurality of apertures extending from the outer surface to the inner surface; a rotatable housing having an outer wall rotatably received around at least a portion of the outer surface of the stationary plug, the outer wall having a plurality of apertures that align with the plurality of apertures of the stationary plug when the rotatable housing is in a first operational position; a bolt member fixedly secured to and depending away from the outer wall of the rotatable housing; and a locking mechanism movably disposed in the plurality of apertures of the rotatable housing, the locking mechanism extending into the plurality of apertures of the stationary plug when the rotatable housing is in the first position, wherein the locking mechanism is configured to retract into the plurality of apertures of the rotatable housing to allow rotation of the rotatable housing about the stationary plug when the key is inserted into the first aperture, the rotatable housing being configured to rotate from the first operational position to a second operational position without rotational movement of the key and in response to a force being applied to the bolt member; and an enclosure configured to receive the stationary plug and the rotatable housing therein, the stationary plug being fixedly secured to the enclosure thereby preventing movement of the stationary plug.
