An exemplary noise-reducing mechanism for door hardware includes a housing, a damper, and a stop. The door hardware includes a first component and a second component, and an operational movement of the door hardware causes relative movement of the first and second components. The housing is mounted to the first component, and the damper is mounted to the housing. The stop is mounted to the second component such that the stop engages the damper during the operational movement. The damper is configured to slow the operational movement, thereby reducing noise generated by operation of the door hardware.

Door hardware noise reduction and evaluation

The present disclosure defines a lever handing apparatus that permits simplified changing of the handing of a lever handle between a left hand and a right hand orientation. The lever handing apparatus includes an assembly with a rotatable spring cage housing and lever spindle that can be selectively rotated within an escutcheon housing to change the handing position of a lever arm. The handing orientation of the lever can be repositioned without removing a back plate or accessing internal components positioned within the escutcheon housing assembly.

Simplified lever handing apparatus

An handleset including a housing, a spring cage assembly, a spindle, and a lever handle. The spring cage assembly includes a spring cage rotatably mounted in the housing, and a bias mechanism biasing the spring cage toward a home position. The spindle extends along a longitudinal axis, and is longitudinally movable between an engaged position in which the spindle is rotationally coupled with the spring cage and a disengaged position in which the spindle is rotationally decoupled from the spring cage. The lever handle is rotationally coupled with the spindle, and the spindle is slidable relative to the lever handle between the engaged position and the disengaged position.

Lever handing selection

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.

Modular clutching mechanism

An exemplary modular hold-open device is configured for use with a door closer comprising a body, a pinion rotatably mounted to the body, and an armature connected with the pinion. The modular hold-open device is configured to be mounted to the door closer, to selectively prevent rotation of the pinion by exerting on the pinion a resistive torque in a door-opening direction, and to cease exerting the resistive torque in response to a door-closing torque on the pinion exceeding a threshold torque to thereby permit rotation of the pinion in the door-closing direction.

Modular hold-open device for door closers

A lock assembly is disclosed to lock a moveable structure to a fixed structure. The lock assembly includes an electric actuator operable to move a locking lug between first and second axial positions to correspond with a locked and unlocked configuration of the lock assembly. A resilient member can couple the locking lug to the electric actuator and drive the locking lug between the first and second positions.

Electronic lock with movable in-line locking lug

A lever apparatus having a lever connected to a latch assembly operable to open the latch when rotated to a second position from a first position under an actuation torque. The apparatus further includes a magnet assembly with first and second magnets operably coupled to the lever apparatus. The magnet assembly is operable to generate a return torque in an opposite direction to that of the actuation torque such that the lever is returned to the first position after the actuation torque is removed from the lever.

Lever return mechanism using magnets

An exemplary armature assembly is configured for use with a door control mounted to one of a door or a doorframe. The door control includes a rotatable pinion, and the armature assembly includes an armature, a shoe, and an elastic component. The armature has a first end and an opposite second end, and the first end includes an opening sized and shaped to receive the pinion at a first interface. The shoe is configured for mounting to the other of the door or the doorframe, and the second end of the armature is pivotally connected to the shoe at a second interface. In certain forms, the elastic component coupled with the armature and configured to absorb mechanical shocks at one of the first interface or the second interface. In certain forms, the elastic component is configured to absorb mechanical shocks along the length of the armature.

Door control armature assemblies

An exemplary damper module is configured for use with a latchbolt assembly, and generally includes a mounting bracket, a first slowing mechanism, and a second slowing mechanism. The latchbolt assembly generally includes a drive member, a latchbolt, and a retractor connected between the drive member and the latchbolt. Each of the slowing mechanisms is independently operable to slow the extension speed of the latchbolt. The first slowing mechanism includes a rack gear and a rotary damper including a pinion gear. The rack gear is configured to be mounted to the drive member, and the rotary damper is mounted to the mounting bracket. The second slowing mechanism includes a slowing arm and a biasing member engaged with the slowing arm. The slowing arm is movably mounted to the mounting bracket and is configured to engage the retractor.

Modular add-on devices for door closers

A lockset including a bolt mechanism, an exterior assembly, an interior assembly, a driving tailpiece, and a driven tailpiece. The bolt assembly includes a bolt having an extended position and a retracted position. The exterior assembly includes a rotatable exterior manual actuator. The interior assembly includes a clutch having a coupling state and a decoupling state. The driving tailpiece is connected between the exterior manual actuator and the clutch. The driven tailpiece is connected between the clutch and the bolt mechanism such that rotation of the driven tailpiece actuates the bolt assembly. In the coupling state, the clutch couples the driving tailpiece with the driven tailpiece such that the exterior manual actuator is operable to actuate the bolt assembly. In the decoupling state, the clutch decouples the driving tailpiece from the driven tailpiece such that the exterior manual actuator is inoperable to actuate the bolt assembly.

Electronic lock with clutch

An exit device according to one embodiment includes a plurality of sensors and an electronic dogging mechanism. The exit device is configured to locally analyze sensor data to determine the security state of the exit device, report data to a management system via a wireless communication channel established between the exit device and the management system, and receive and process instructions to perform an electronic dogging operation.

Exit device systems and methods

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.
