An exemplary exit device system includes a pushbar assembly and a control system. The pushbar assembly includes a latch having an extended position and a retracted position, a blocking member having a blocking position in which the blocking member retains the latch in the extended position and an unblocking position in which the blocking member permits the latch to move to the retracted position, a pushbar operable to move the blocking member between the blocking position and the unblocking position, and an electronic driver operable to move the blocking member between the blocking position and the unblocking position. The control system is configured to operate the electronic driver to electrically move the blocking member between the blocking position and the unblocking position based upon information received from a credential reader.

Exit device assembly with integrated access control

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 retrofit module configured for use with a door closer having a pinion. The retrofit module generally includes a case, an output shaft, a motor, and a control assembly. The output shaft is rotatably mounted in the case, and is configured for rotational coupling with the pinion. The motor is mounted to the case, and is operable to rotate the output shaft in a door-opening direction. The control assembly is mounted to the case, and is configured to operate the motor to drive the output shaft in the door-opening direction in response to an actuating signal.

Powered opening module for a door closer

A door closer system is provided that includes a motor, a spring, a reduction gear set, and a rack and a pinion mechanism. The spring and pinion may be coupled to the rack, and the pinion may be selectively coupled to the gear set. The motor may be selectively mechanically coupled to the gear set. The pinion may rotate in a first direction via the rack as the spring is compressed in a second direction opposite the first direction as the spring is expanded. The motor is operable to rotate and act upon the pinion through the gear set, thereby rotating the pinion in the second direction and assist the spring in closing the door.

Door closer system

Certain embodiments relate to an adjustment indicator mechanism for a door closer including a tubular portion and an adjustment screw mounted to the tubular portion. A housing is configured for mounting to the door closer, and includes a channel and indicia adjacent the channel, each of the indicia corresponding to a respective size of the door closer. An adjustment transmission includes a first component configured for coupling with the adjustment screw. An indicator transmission is engaged with the adjustment transmission and mounted in the housing. An indicator is movably mounted to the housing such that a portion of the indicator is visible via the channel. The indicator is engaged with the indicator transmission such that movement of the indicator transmission causes the indicator to selectively align with the indicia to thereby indicate the current size of the door closer.

Door closer adjustment mechanism

Modular add-on devices for door closers

An exemplary trim assembly comprises a housing assembly, a cam rotatably mounted to the housing assembly, a lift finger slidably mounted in the housing assembly such that the cam is operable to linearly drive the lift finger between a deactuated position and an actuated position, and a locking mechanism operable to selectively retain the lift finger in the deactuated position. The locking mechanism includes an interface member engaged with the lift finger such that movement of the lift finger moves the interface member between a home position and an offset position, a blocking member operable to selectively prevent movement of the interface member from the home position, and a driver configured to move the blocking member between a blocking position and an unblocking position to thereby lock and unlock the trim assembly.

Motorized trim

An exemplary door closer has an adjustable size and includes a rotatable member operable to adjust the size and an indicator mechanism configured to indicate the current size. The indicator mechanism includes a cover mounted to a housing of the door closer and a dial rotatably mounted to the cover. The dial is engaged with the rotatable member such that the dial rotates in response to rotation of the rotatable member. The cover includes an indicating region, and the dial includes a display surface including indicia relating to the sizes of the door closer. The display surface is non-perpendicular to the rotational axis of the rotatable member. When the door closer has been adjusted to a particular size, indicia relating to the particular size are indicated by the indicating region.

Door closer power adjustment

An exemplary door closer includes a housing defining a hydraulic chamber having a hydraulic fluid disposed therein. A pinion is rotatably mounted to the housing and extends into the hydraulic chamber. A piston is mounted for reciprocal movement within the housing, and defines a rack engaged with the pinion. The housing further defines an aperture in fluid communication with the hydraulic chamber. A regulating screw is rotatably mounted within the aperture such that rotation of the regulating screw in a first direction advances the regulating screw into the hydraulic chamber and such that rotation of the regulating screw in an opposite second direction withdraws the regulating screw away from the hydraulic chamber. A stop member is mounted in the aperture such that the stop member limits withdrawing movement of the regulating screw to thereby prevent leaking of the hydraulic fluid from the hydraulic chamber via the aperture.

Door closer with backout prevention

A valve mechanism according to certain embodiments includes an adjustment screw and a rotatable control knob coupled with the adjustment screw. The valve mechanism includes a feedback mechanism operable to provide at least one of visual feedback, audible feedback, or tactile feedback to indicate movement and/or a positon of the adjustment screw within a door closer body.

Door closer apparatus and method

A door closer system is provided that includes a motor, a spring, a reduction gear set, and a rack and a pinion mechanism. The spring and pinion may be coupled to the rack, and the pinion may be selectively coupled to the gear set. The motor may be selectively mechanically coupled to the gear set. The pinion may rotate in a first direction via the rack as the spring is compressed in a second direction opposite the first direction as the spring is expanded. The motor is operable to rotate and act upon the pinion through the gear set, thereby rotating the pinion in the second pinion direction and assist the spring in closing the door.

A control assembly configured for a narrow stile door and for interaction with an exit device. The control assembly provides a means to translate user input, such as rotating a lever to operate a centercase. The control includes a slider for sliding movement within a housing between a first position extending a latchbolt of the exit device and a second position withdrawing the latchbolt. The control assembly configuration incorporates a swivel locking latch rotatable into the path of the slider to prevent the slider from moving out of the first position.
