Patent number: 11885152Abstract: Lock indicators useable to signal the locked or unlocked state of a lock at both sides of a door selectively secured by the lock. Lock indicators include a first cuff for receiving an input causing the first cuff to transition from a first position to a second position associated with the locked state and the unlocked state. The lock indicators include a second cuff for receiving input from the first cuff via a transmission rod causing the second cuff to transition from a first position to a second position associated with the locked state and the unlocked state.Type: GrantFiled: June 22, 2021Date of Patent: January 30, 2024Assignee: dormakaba USA Inc.Inventor: Jason C.

Patent number: 11613910Abstract: A system including a lock class having a plurality of lock families, with each lock family including a plurality of lock cylinders. Each of the lock families has a control pin location which is different from the control pin location of another of the lock families within the lock class. Each of the lock cylinders generally includes a shell, a plug rotatably mounted in the shell, and a control ring rotatably mounted on the plug at the control pin location of the lock family of which the lock cylinder is a member, and a control pin operable to selectively couple the plug with the control ring. Each lock family may be associated with a control key family. Each control key family may include a plurality of control keys, each of which may have a control bitting configured to urge control pins of the associated lock family to a coupling position.Type: GrantFiled: April 30, 2019Date of Patent: March 28, 2023Assignee: Schlage Lock Company LLCInventor: Jason C.
