20100263418 | Mortise Lock Assembly - Several new components are provided for a mortise lock. First, a non-handed clutching assembly, including a pair of spindle hubs rotatable within a pair of outer hubs, is provided for a mortise lock. Second, a spindle-mounted lock-handing selector—which can be removed from one side of the lockset body while the lockset body is installed in the mortise of a door—is provided to set the handing of the clutching assembly. Third, an escapement mechanism is provided for a reciprocating-slide-based clutch-actuator assembly, enabling the slides to move into a position biasing a locker-carrying lever toward a hub-coupling position, even if the outer and spindle hubs are misaligned. Fourth, a guardbolt-actuated blocking assembly for a lockset is provided to block movement of the stop works or clutch works when the door is closed and the outside door handle is disabled. | 10-21-2010 |
20120013135 | Mortise Latchset with Dually Biased Cam Assembly - A mortise latchset has an improved leveraged cam assembly, completely internal to the latchset body, versatile enough to allow the door handles to be rotated in either direction to retract the latchbolt, and robust enough to independently bias each of two lever-type door handles toward a handle-centering position, even when one of the handles is being operated. The mortise latchset uses a pair of coaxially mounted cam followers independently leveraged by a cantilevered spring assembly. The cam followers are located between the operating cams and the latch retracting assembly, and each leveraged cam follower is operable to engage the latch retracting assembly to retract the latchbolt, while the other cam follower biases its operating cam in the handle-centering position. | 01-19-2012 |
20120198896 | Mortise Lock Assembly - A mortise lock is provided with independently rotatable spindles and a highly accessible lock-handing selector. Also, a clutching mortise lock is provided that enables operative rotation in both directions to retract the latch. | 08-09-2012 |
20130239631 | Cylindrical Lockset - A cylindrical lockset comprises a multiple-compartment lock cage subassembly. A retractor is housed within a middle lock cage compartment. Spindle return torsion springs, for biasing corresponding handle-carrying spindles to their default positions, are housed within axially adjacent lock cage compartments. A torque plate transfers torque from the lock cage subassembly to relatively radially distal trim posts. A knob catch assembly seated in each handle-carrying spindle comprises a generally elliptically-shaped wrap around catch spring and a knob catch backup washer to resist axial loads produced by efforts to pull a handle off of the spindle. A key spindle provides a dog travel window defined by a closed, continuous edge of the key spindle, which window is positioned opposite of an axially-extending seam of the key spindle. | 09-19-2013 |
20130239632 | Cylindrical Lockset - A cylindrical lockset comprises a multiple-compartment lock cage subassembly. A retractor is housed within a middle lock cage compartment. Spindle return torsion springs, for biasing corresponding handle-carrying spindles to their default positions, are housed within axially adjacent lock cage compartments. A torque plate transfers torque from the lock cage subassembly to relatively radially distal trim posts. A knob catch assembly seated in each handle-carrying spindle comprises a generally elliptically-shaped wrap around catch spring and a knob catch backup washer to resist axial loads produced by efforts to pull a handle off of the spindle. A key spindle provides a dog travel window defined by a closed, continuous edge of the key spindle, which window is positioned opposite of an axially-extending seam of the key spindle. | 09-19-2013 |
20140196509 | Attack-Thwarting Cylindrical Lockset - Mechanisms are provided to thwart an overtorquing attack on a cylindrical lockset. The cylindrical lockset comprises a lock cage, a split retractor assembly, and a torque-attack-activated spring-loaded blocker assembly coupled to the lock cage. The blocker assembly is set to a default non-blocking configuration. An overtorquing attack triggers the blocking assembly into a blocking setting. When in the blocking setting, the blocking assembly blocks movement of at least an outside door portion of a retractor assembly from translating into a latch-retracting position, but does not block the inside door handle from retracting the latch. A new split retractor assembly is also provided. | 07-17-2014 |
