  • 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.

  • Patent number: 10557288
    Abstract: A hoop lock assembly including a shackle and a crossbar. The shackle includes a straight foot and an angled foot. The crossbar is operable to receive the straight foot and the angled foot, and includes a primary locking mechanism and a secondary locking mechanism. The primary locking mechanism is operable to selectively prevent removal of the straight foot from the crossbar. The secondary locking mechanism is operable to selectively prevent removal of the angled foot from the crossbar.
