Claim:
A locker system, comprising: a locker; a door pivotally mounted to the locker; a locking device for locking the door to the locker, wherein the locking device does not require rotational movement of a key for unlocking the locking device, the locking device comprising: a stationary plug fixedly secured to an enclosure of the locking device, the stationary plug having a first aperture extending therein, the first aperture being configured to receive the key; a first plurality of apertures extending from an outer surface of the stationary plug into the first aperture; an outer housing rotatably received about a portion of the stationary plug, the outer housing having a second plurality of apertures configured to align with the first plurality of apertures when the outer housing is in a first position with respect to the stationary plug; a bolt member fixedly secured to and depending away from the outer housing; and a locking mechanism movably disposed in the first and second plurality of apertures, the locking mechanism extends into the first plurality of apertures when the rotatable housing is in the first position and the key is not inserted in the first aperture, wherein movement of the outer housing is prevented when the locking mechanism extends into the first plurality of apertures and wherein the locking mechanism retracts into the second plurality of apertures of the outer housing when the key is inserted in the first aperture and the outer housing is in the first position, wherein rotational movement of the outer housing about the stationary plug is allowed when the key is inserted in the first aperture, the outer housing being configured to rotate from the first position to a second position in response to a force being applied to the bolt member and without rotational movement of the key and the stationary plug; and wherein the stationary plug is fixedly secured to the enclosure and the enclosure is fixedly secured to the locker.
