Abstract: An exemplary clutch mechanism includes a casing, first and second hubs rotatably mounted to the casing, an electrically-actuated drive assembly mounted within the casing, and a clutching lug movably mounted within the casing. The lug has an engaged position in which the lug couples the hubs for joint rotation and a disengaged position in which the hubs are rotationally decoupled. The drive assembly is operable to drive the lug between the engaged and disengaged positions to couple and decouple the hubs. The clutch mechanism is modular and self-contained within the casing such that the mechanism can be installed to each of a plurality of different lockset products without opening the casing.

Abstract: Lock devices, systems, and methods that can include an internal mechanism to permit backdriven operation and lost motion operation. In one form the lock includes an assembly of parts that includes parts having locating features that that can assist in those parts being assembled with other parts of the assembly in a single, relative orientation.

Abstract: The present disclosure is directed to a lock assembly that can be converted between a clutching and non-clutching orientation by rotating an outer housing 180 degrees relative, to an outside drive assembly. The outer housing includes a notch and an elongate arcuate slot formed in the inner surface of the outer housing adjacent a through aperture and across from one another. A lock control lug is moveably coupled with the outside drive assembly and is selectively engageable with the notch or the arcuate slot of the outer housing. An outer lever is placed in a non-clutching configuration when the lock control lug is engaged with the notch and in a clutching configuration when the lock control lug is engaged with the arcuate slot.

Abstract: The present disclosure is directed to a lock assembly comprising an inner housing positionable on one side of a movable structure such as a door and an outer housing positionable on an opposing side of the structure. A pocket connection region having an aperture formed through a wall of the inner housing is configured to receive a head of a fastener therethrough. After the fastener extends through the aperture, a clamp device may be moved from an open position to a closed position so as to releasably lock the fastener to the pocket connection region of the inner housing. In another form, a retainer is configured to hold the fastener with respect to the inner housing during installation of the lock assembly. In this manner an inner housing may be quickly connected to an outer housing when installing a lock assembly to the structure.

Abstract: An exemplary product line system includes a common platform and a plurality of component families, each of which includes a plurality of interchangeable component species configured for use with the common platform. The common platform includes an inside drive assembly and a chassis assembly including a chassis and an outside drive assembly. A lockset assembled from the system includes the common platform and a plurality of modular components. Each of the modular components corresponds to a respective one of the component families, and is provided as a selected species of the corresponding component family. The lockset has a function defined by the set of component species installed to the lockset. The function of the lockset can be changed by altering the set of component species installed to the lockset without disassembling the chassis assembly.

Abstract: A latch assembly configured to attach to a door includes one of a knob and a lever. The latch assembly further includes a latch extending from the door. A spindle is rotatable from a first position to a second position to move the latch from an extended position to a retracted position. A first biasing member is selectively operable to bias the spindle toward the first position. A second biasing member is selectively operable to bias the spindle toward the first position. An actuator is movable between a knob position in which only one of the first biasing member and the second biasing member biases the spindle toward the first position and a lever position in which both the first biasing member and the second biasing member cooperate to bias the spindle toward the first position.

Abstract: A spring air gun includes a reciprocable piston and a slide for cocking the piston. The slide is movable between forward and rearward positions. A piston rod is connected to the slide and is slidably mounted within a piston tube which is connected to the piston. A pair of springs are concentrically mounted on the piston tube, and the forward end of each spring engages the piston. The rearward end of the inner spring engages the slide, and the rearward end of the outer spring engages the frame of the gun. A detent maintains the slide in the forward position, and a sear maintains the piston in the cocked position and is engageable with the detent for preventing the slide from moving rearwardly until the gun is fired. The gun is fired by pulling a trigger, which releases the sear from the piston. The detent can then be moved to allow the slide to be moved rearwardly to cock the piston. When the slide is not in the forward position, the detent prevents the trigger from being pulled.

Abstract: A gun with a pivoting barrel includes a compression tube having a forked front end and a fork member which is inserted into the front end of the compression tube. The fork member includes a cylindrical body which is inserted into the compression tube and a pair of forked arms which extend along the inside of the forked end of the compression tube. A barrel is pivotably connected to the forked ends of the fork member and the compression tube. A spring clip on the barrel engages a stud on the fork member for releasably retaining the barrel in a firing position. A cocking lever connected to the barrel is engageable with a trigger extension for preventing the trigger from being pulled when the barrel is not in the firing position.

Abstract: A frequency generating circuit and a cap-freeing mechanism in a bolt are responsive to a longitudinal movement of a piston in response to overheating of an associated bearing. The cap-freeing mechanism transfers a force from the piston to a cap, thereby freeing the cap from a head portion of the bolt and allowing an antenna to extend to the outside of the bolt. The frequency generating circuit is activated by a connection made between a switch and a battery of the circuit by the piston. Upon becoming activated, the frequency generating circuit sends a predetermined frequency or frequency pattern through the antenna.
