ABSTRACT:
A locking mechanism includes a centering axle having an engaging member defined at one end thereof, a sleeve encompassing a portion of the centering axle, and a clutch device that securely receives the sleeve and permits rotation of the centering axle and the sleeve in only one direction. The centering axle defines a plurality of equally spaced grooves, and the sleeve defines a plurality of equally spaced grooves corresponding to the grooves of the centering axle in an opposed manner. Each pair of opposed grooves of the centering axle and sleeve define a narrow passageway that accommodates a ball bearing that is slidable along the longitudinal axis of the centering axle and between the sleeve and centering axle. The ball bearing in each passageway permits longitudinal movement of the centering axle relative to the sleeve and prohibits rotation of the centering axle relative to the sleeve.
