  • Patent number: 11885151
    Abstract: A keycam assembly including a rotatable member, a stem, a locking member coupled to the stem for joint longitudinal movement therewith, and a cam driver. The rotatable member includes an aperture. A proximal end portion of the stem is rotatably seated in the rotatable member and defines a cam track. The locking member extends between the aperture and the cam track. The cam track includes a first passage including a locking pocket, a second passage including an unlocking pocket, a first ramped passage including a locking ramp extending from the second passage to the locking pocket, and a second ramped passage including an unlocking ramp extending from the first passage to the unlocking pocket. Relative rotation of the rotatable member and the stem causes the cam driver to travel along the track to thereby cause movement of the locking member between a locking position and an unlocking position.
