Patent number: 11781342Abstract: An exemplary strike box is configured for use with a lockset including a bolt operable to move in an extending direction and a retracting direction. The strike box includes a housing having an opening sized and configured to receive the bolt, and further includes a bolt-slowing mechanism mounted in the housing. The bolt-slowing mechanism is configured to engage the bolt as the bolt moves in the extending direction, and to exert a force urging the bolt in the retracting direction. The force exerted by the bolt-slowing mechanism slows the extension speed of the bolt, such that the strike box reduces noise generated during such extension.Type: GrantFiled: June 29, 2021Date of Patent: October 10, 2023Assignee: Schlage Lock Company LLCInventors: Bhargav Yalamati, Prabhat Kumar Yadav

Patent number: 11725423Abstract: 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.Type: GrantFiled: November 24, 2020Date of Patent: August 15, 2023Assignee: Schlage Lock Company LLCInventors: Bhargav Yalamati, Chetan V, Sachin Chandra Shetty, Prabhat Kumar Yadav
