Patent number: 11920388Abstract: A retention bracket configured for use with a latch mechanism including a laterally extending housing. The retention bracket includes a first wall, a second wall, a collar, and a deformable section. The first and second walls are longitudinally offset from one another and are structured to receive the housing therebetween. The collar extends longitudinally outward from one of the walls and defines an opening having an effective diameter. The deformable section has a natural state in which the effective diameter is a first diameter, and a deformed state in which the effective diameter is a second diameter greater than the first diameter.Type: GrantFiled: March 9, 2021Date of Patent: March 5, 2024Assignee: Schlage Lock Company LLCInventor: Nathanael S.

Patent number: 11828088Abstract: 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: GrantFiled: February 1, 2022Date of Patent: November 28, 2023Assignee: Schlage Lock Company LLCInventors: Hassan C.

Patent number: 11359402Abstract: An apparatus including a chassis assembly having a housing, a spindle rotatably mounted to the housing, a spring collar rotatably mourned 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: GrantFiled: March 24, 2020Date of Patent: June 14, 2022Assignee: Schlage Lock Company LLCInventors: Michael Holman, Nathanael S.

Patent number: 11332956Abstract: A rose assembly for a door lock and a method of removably securing the rose assembly to a lock chassis. The rose assembly is secured to the lock chassis through the use of an intermediate spring steel attaching plate, which provides both a secure attachment to the lock and orientation of the rose assembly to the lock housing. A single spring plate with integrated retention clip features provides a removably attachable interface between the rose and the lock chassis. The spring plate includes a hook feature to provide positive retention of the rose that is independent of the spring clip features. Additionally, the spring clips are located to minimize the possibility that one clip deflects substantially more than another. The installation process includes inserting the hook feature into a slot in the chassis housing, and then snapping the clip features over the housing to seat and retain the rose.Type: GrantFiled: March 22, 2017Date of Patent: May 17, 2022Assignee: Schlage Lock Company LLCInventor: Nathanael S.

Patent number: 11236524Abstract: 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: GrantFiled: December 17, 2019Date of Patent: February 1, 2022Assignee: Schlage Lock Company LLCInventors: Nathanael S. Murphy, Peter Malenkovic

Patent number: 11220837Abstract: 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 rotable 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: December 10, 2019Date of Patent: January 11, 2022Assignee: Schlage Lock Company LLCInventors: Nathanael S.

Patent number: 10900254Abstract: A lock for a door including a configurable lock function. The lock includes a removable and user accessible actuator which when removed from the lock disables a lock function, and when inserted into the lock enables the lock function. Removal of the actuator places the lock in a disabled condition in which the lock cannot be locked by other means. Insertion of the actuator into the lock places the lock in an enabled condition in which the lock is locked or unlocked by the position of the actuator. The lock is installed without the actuator when the lock is intended to be used only in a passage operation where the door provides access only, but does not restrict access. The lock is installed with the actuator when the lock is intended to be used in a privacy operation where the lock is intended to restrict access to an area.Type: GrantFiled: December 4, 2018Date of Patent: January 26, 2021Assignee: Schlage Lock Company LLCInventors: Nathanael S.

The handle includes a shank having a load bearing section, a primary actuating section, and a secondary actuating section. The chassis includes a housing, a support spindle, a primary actuator, and a secondary actuator. The support spindle is longitudinally coupled with the load bearing section, and the primary actuator is rotationally coupled with the primary actuating section of the handle. The handle set has a first configuration in which the secondary actuating section is engaged with the secondary actuator, and a second configuration in which the secondary actuating section is disengaged from the secondary actuator.Type: ApplicationFiled: July 28, 2020Publication date: January 14, 2021Inventors: Nathanael S.
