ABSTRACT:
A free-wheeling lock assembly includes a free-wheeling lock mechanism which prevents damaging forces from being applied to the components of the lock assembly if the lock cylinder is forcibly rotated by a key other than the proper key or by some other instrument. A detent mechanism, which functions independent of spring bias, couples the sleeve to the case in the presence of the proper key in the keyway. A clutch mechanism couples the cylinder to the driver, but decouples the driver from the cylinder for an over-torque condition. The cylinder lock assembly further includes a locking mechanism which prevents operation of the latching mechanism of the lock assembly if the cylinder is slam-pulled from the case. The tumblers are isolated from rotary motion of the tumbler ward.
