  • Quiet latch for a locking device
    Patent number: 11725423
    Abstract: A locking device for a door located at a door frame having a door strike. The locking device includes an actuator having a neutral position and a displaced position, and a latchbolt assembly having an extended position configured to engage the door strike, and a retracted position configured to move past the door strike. The latchbolt assembly includes a latchbolt link configured to move the latchbolt in response to movement of the actuator. A first dampening device is disposed adjacent to the latchbolt link, with the dampening device resiliently engaging the latchbolt link as the latchbolt link moves from the retracted position to the extended position. The first dampening device limits movement of the latchbolt link. A second dampening device is configured to restrain movement of the latchbolt during movement from the retracted position to the extended position.
