  • AXIAL CLUTCH MECHANISM
    Publication number: 20240125149
    Abstract: An exemplary trim assembly comprises an escutcheon, a drive spindle, a lock mechanism, a cam mechanism, and a driver. The drive spindle is mounted to the escutcheon for rotation about a longitudinal axis. The lock mechanism includes a lock gear movably mounted in the escutcheon. The cam mechanism includes a first cam defined by the escutcheon and a second cam defined by the lock gear. The driver is operable to rotate the lock gear between a first rotational position and a second rotational position. The cam mechanism is configured to longitudinally drive the lock gear from a first longitudinal position to a second longitudinal position as the lock gear rotates from the first rotational position to the second rotational position. Movement of the lock gear between the first longitudinal position and the second longitudinal position transitions the lock mechanism between a locked state and an unlocked state.
