An exemplary pushbutton mechanism is configured for use with a lockset including a spindle and a plunger extending into the spindle, and generally includes a first component, a second component, and a cam interface. The first component is configured for rotational coupling with the plunger and for axial coupling with the spindle, and is rotatable between a locking orientation and an unlocking orientation. The second component is configured for rotational coupling with the spindle and for axial movement relative to the first component and the spindle, and is axially movable between a depressed position and a projected position. The cam interface is configured to correlate rotation of the first component with axial displacement of the second component.

Pushbutton mechanisms for locksets

An exemplary method relates to operating a door closer assembly including a closer body, a pinion rotatably mounted to the closer body, a motor including a motor shaft, and a bidirectional clutch connected between the pinion and the motor shaft. The method generally involves permitting, by the clutch, rotation of the pinion in each of a first direction and a second direction without transmitting rotation of the pinion in either direction to the motor shaft; sensing, with a sensor, a rotational position of the pinion; comparing, by a controller, the rotational position of the pinion with a desired rotational position; based upon the comparing, driving the motor to rotate the motor shaft; and by the clutch, coupling the motor shaft with the pinion in response to rotation of the motor shaft, thereby transmitting torque from the motor shaft to the pinion and urging the pinion toward the desired rotational position.

Latch mechanisms adapted to prevent unauthorized displacement of a latch bolt from an extended, locked position to a retracted, unlocked position. The latch mechanisms prevent the failure of a latch bolt of one latch mechanism to return to an extended lock position from interfering with the ability of a latch bolt of an inter-related latch mechanism from being able to return to an extended, locked position. Further embodiments provide a mounting bracket mounted to a door to allow the associated latch mechanism to be indirectly secured to the door. Additionally, the mounting bracket may have a plurality of mounting orifices that allow the mounting bracket to be used with a wide range of latch mechanisms, as well as provide adjustable attachment of the latch mechanism to the mounting bracket.

Adjustable dead-latching bolt mechanisms

An exemplary armature assembly is configured for use with a door closer comprising a pinion, and generally includes a first arm configured for rotational coupling with the pinion, a second arm pivotably coupled to the first arm at a pivot joint, and a hold-open mechanism. The hold-open mechanism generally includes a clutch having a decoupling and a coupling state, and an electromechanical driver operable to transition the clutch between the coupling state and the decoupling state. With the clutch in the decoupling state, a first torque is operable to cause relative pivoting of the arms. With the clutch in the coupling state, the first torque is inoperable to cause relative pivoting of the arms, and a second torque greater than the first torque is operable to cause relative pivoting of the arms.

An exemplary credential input device includes a mounting plate, a pivot pad, a sensor, an input device, and a controller. The pivot pad is pivotably mounted to the mounting plate, is biased to a home position, and is operable to pivot to each of a plurality of pivoted positions. The sensor is mounted to the pivot pad such that the sensor moves with the pivot pad, and is configured to generate information relating to an orientation of the sensor. The input device operable to move the pivot pad from the home position to each of the plurality of pivoted positions, thereby altering the orientation of the sensor. The controller is in communication with the sensor, and is configured to determine an inputted code based upon information received from the sensor, to compare the inputted code to an authorized code, and to issue a command in response to the comparing.

A hoop lock assembly including a shackle and a crossbar. The shackle includes a straight foot and an angled foot. The crossbar is operable to receive the straight foot and the angled foot, and includes a primary locking mechanism and a secondary locking mechanism. The primary locking mechanism is operable to selectively prevent removal of the straight foot from the crossbar. The secondary locking mechanism is operable to selectively prevent removal of the angled foot from the crossbar.

Adjust dead-latching bolt mechanisms

A door lock includes a deadbolt and a latchbolt each movable between a thrown position and a retracted position, an inside lever operable to move the latchbolt between the thrown and retracted positions, and an outside lever configured in one of a locked and unlocked state in which the outside lever is operable to move the latchbolt between the thrown and retracted position. A thumbturn is coupled to the deadbolt and is movable between a first position in which the deadbolt is in the thrown position, the latchbolt is in the thrown position, and the outside lever is locked, a second position in which the deadbolt is in the retracted position, the latchbolt is in the thrown position, and the outside lever is locked, and a third position in which the deadbolt is in the retracted position, the latchbolt is in the thrown position, and the outside lever is unlocked.

Privacy override function for a door lock

A lock assembly that has a locked state and an unlocked state. The lock assembly includes a latch assembly that has a latch and a clutch mechanism. The clutch mechanism includes a first retractor that is movable in response to movement of an interior handle assembly and selectively in response to movement of the exterior handle assembly, and a second retractor that is movable in response to movement of the interior handle assembly and the exterior handle assembly. The first retractor is always engaged with the latch assembly to move the latch between the extended position and the retracted position. The second retractor is selectively disengaged from the latch assembly and is movable relative to the first retractor when the lock assembly is in the locked state.
