Patent number: 11913249Abstract: An exemplary lock apparatus includes a housing and a plug assembly rotatably mounted in the housing. The plug assembly includes a tumbler assembly operable to selectively prevent rotation of the plug assembly relative to the housing and a retention mechanism operable to selectively prevent removal of the plug assembly from the housing. A system including the lock apparatus may include a change key configured to actuate the tumbler assembly without actuating the retention mechanism and/or a control key configured to actuate both the tumbler assembly and the retention mechanism.Type: GrantFiled: March 15, 2022Date of Patent: February 27, 2024Assignee: Schlage Lock Company LLCInventors: James Nye, Brian E. Walls

Publication number: 20240011332Abstract: An exemplary portable lock apparatus generally includes a shackle and a crossbar. The crossbar includes a lock mechanism operable to selectively secure the shackle to the crossbar in a closed condition. The shackle includes a rigid shackle core and a cover layer covering at least a portion of the shackle core. The cover layer includes a ceramic material.Type: ApplicationFiled: July 7, 2022Publication date: January 11, 2024Inventors: Carter Kemper, Brian E. Walls

Patent number: 11713595Abstract: A door lock chassis has a gauge insert that defines different dimensions corresponding to different door thicknesses. The gauge insert is positionable in the lock chassis in different orientations corresponding to the different dimensions used to align the lock chassis for different door thicknesses. Additionally, a door lock may include an anti-rotation assembly for preventing rotation of the lock chassis. The anti-rotation assembly may include a retention member that is secured to an inside hub of a lock chassis. As an anti-rotation member is displaced in a first axial direction along the inside hub to a mount position, the anti-rotational member may deflect resilient members of the retention member. With the anti-rotation member at the mounted position, the anti-rotation member may be in a frictional engagement with the previously deflected resilient members so that anti-rotation member is retained at the mount position.Type: GrantFiled: December 29, 2020Date of Patent: August 1, 2023Assignee: Schlage Lock Company LLCInventors: Brian E. Walls, Rich D. Shelinbarger, Scott D. Welsby, Peter Malenkovic

Patent number: 11702862Abstract: A plug assembly including a plug, a sidebar movably mounted on the plug, and a plurality of rack pins seated in the plug. The sidebar is biased to an outer position in which the sidebar extends beyond an outer surface of the plug. Each rack pin includes a key-following leg and a sidebar-engaging leg. The sidebar-engaging leg includes at least one true gate. When a true gate of each rack pin is aligned with the sidebar, the sidebar is free to move radially inward to an inner position.Type: GrantFiled: August 18, 2020Date of Patent: July 18, 2023Assignee: Schlage Lock Company LLCInventors: Brian E. Walls, Jason C. Clifford, Scott D. Welsby
