Abstract

An exemplary handle assembly including a handle and a coupling mechanism. The handle includes a shank and a manually graspable portion extending from the shank. The coupling mechanism includes a coupling member and a cam sleeve. The coupling member is mounted to the shank for movement between a coupling position and a decoupling position. The cam sleeve is movably mounted to the shank and covers the coupling member. A radially-inner portion of the cam sleeve includes a cam surface operable to engage the coupling member. The cam surface is configured to drive the coupling member from the decoupling position to the coupling position as the cam sleeve is displaced from a home position to a displaced position.
