Patent number: 10501962Abstract: A lock device that prevents operation of at least one chassis spindle from retracting a latch bolt, and which may provide auto-unlock features. Locking of the lock device can effectuate linear displacement of a slider body from an unlocked position to a locked position. Linear displacement of the slider body is translated into rotational displacement of a cam body that includes, or is coupled to, a locking shaft having a cam protrusion, thereby rotating the cam protrusion. As the cam protrusion rotates, the cam protrusion lifts a locking lug to a locked position wherein the locking lug prevents rotational displacement of a first chassis spindle. When in the locked position, a slider arm of the slider body can be positioned in a retention slot. Subsequent rotatable displacement of a second chassis spindle can effectuate displacement of the slider arm from the retention slot and facilitate unlocking of the lock device.Type: GrantFiled: March 22, 2017Date of Patent: December 10, 2019Assignee: Schlage Lock Company LLCInventors: Nathanael S. Murphy, Peter Malenkovic

Publication number: 20180119453Abstract: 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: ApplicationFiled: August 8, 2017Publication date: May 3, 2018Inventors: Brian E. Walls, Rich D. Shelinbarger, Scott D. Welsby, Peter Malenkovic

Publication number: 20170275917Abstract: An apparatus that at least assists in maintaining a lever or knob of a lock device in a relatively neutral and static position. The apparatus includes a biasing element that can be constructed from a compliant material that may at least assist in reducing impact forces between interfacing surfaces at least when the lever or knob is returns to the neutral, static position from one or more activated positions. The compliant nature of the damper can further alleviate issues relating to manufacturing tolerances and wear between interfacing surfaces.Type: ApplicationFiled: March 22, 2017Publication date: September 28, 2017Inventors: Nathanael S. Murphy, Peter Malenkovic

Publication number: 20170275926Abstract: A latch assembly that is adjustable between first and second backset settings. A cam is rotatable about a cam axis, and facilitates linear displacement of a latch link in a first direction. A multiplier link is rotatable about a multiplier link axis that is offset from the cam axis can be rotated in the first rotational direction by engagement with the latch link. A latch bar is coupled to the multiplier link and is linearly displaced in a second direction by rotation of the multiplier link in the first direction. The latch apparatus also includes a latch bolt that is coupled to the latch bar, the latch bolt being displaced toward a retracted position by the displacement of the latch bar in the second direction. The latch assembly can also include a dead latch link can block retraction of at least the latch bolt.Type: ApplicationFiled: March 22, 2017Publication date: September 28, 2017Inventors: Hassan C. Kumar, Nathanael S. Murphy, Peter Malenkovic, Allen Mani, Madhu H. Siddaramaiah

Publication number: 20170275911Abstract: An apparatus including a chassis assembly having a housing, a spindle rotatably mounted to the housing, a spring collar rotatably mounted to the housing, a first biasing element rotationally urging the spindle toward a spindle home position, and a second biasing element rotationally urging the spring collar toward a spring collar home position. The apparatus may further include a handle mounted on the chassis such that the chassis biases the handle to a handle home position with a return torque. The handle is engaged with the spindle such that the first biasing element contributes to the return torque. In certain embodiments, the handle may further be engaged with the spring collar such that the second biasing element contributes to the return torque.Type: ApplicationFiled: March 23, 2017Publication date: September 28, 2017Inventors: Michael Holman, Nathanael S.
