Abstract
A free-wheeling lock assembly includes a case and a drive mechanism which is adapted for coupling to a latching mechanism. The drive mechanism includes a lock barrel supported within the case for rotational and axial movement relative to the case and a driver releasably coupled to the lock barrel but fixed against axial movement. The drive mechanism further includes first and second slidebars supported within the case for axial movement relative to the case. The slidebars are coupled to the lock barrel by tumblers of the lock assembly, and translate the lock barrel axially with respect to the driver, decoupling the driver from the lock barrel in response to rotation of the lock barrel when the tumblers are in a locking position. However, the tumblers permit relative axial movement between the first and second slidebars and the lock barrel when the tumblers are in a releasing position, permitting the lock barrel to rotate the driver for operating the latching mechanism.
