Abstract: An exemplary indicator mechanism is configured for use with a door closer including a body and an adjustment screw. The indicator mechanism generally includes an indicator, at least one indicium, and a cycloidal drive. The cycloidal drive is configured to selectively align the indicator and the at least one indicium in response to rotation of the adjustment screw to thereby indicate an operating characteristic of the door closer.

Abstract: An apparatus comprises a base plate configured to be coupled to a door, the door configured to be positioned in an open position and a closed position; a closing mechanism coupled to the base plate and configured to be coupled to a hinge of the door and having an unprimed state and a primed state, the closing mechanism configured to be transitioned between the unprimed state and the primed state by a user; wherein in the unprimed state the closing mechanism is decoupled from operation of the door; and in the primed state the closing mechanism is configured to move the door into the closed position responsive to receipt of a signal, and the closing mechanism is configured to allow movement of the door between the open position and the closed position in absence of the signal.

Abstract: A door closer may utilize a door closing device (e.g., spring) and a force adjustment device (e.g., a motor) in order to allow for manual door opening and assisted door closing. During operation, as a door is manually opened, the spring is loaded (e.g., compressed or tensioned) above its pre-loaded closed position state. Once manual opening is completed, the spring that is loaded during opening begins returning to the pre-loaded closed position state, and thus, moves the door automatically towards the closed position. Depending on the pre-loaded spring setting, the closing force of the door may not be enough to close the door, or to close the door with the preferred force. As such, during closing a controller may engage a motor not to drive the door directly, but to increase the pre-load of spring to increase the closing force in order to allow the door to close as preferred.

Abstract: A vertical door latch assembly includes a housing and a bolt movably attached to the housing having a catch portion. A drive motor is located within the housing and is configured to selectively move a lock assembly between a locked position preventing movement of the bolt and an unlocked position allowing movement of the bolt. A controller is in electrical communication with the drive motor and is configured to direct the actuator lock assembly between the locked position and the unlocked position.

Abstract: The unlocking mechanism of the present invention is actuated as a result of contact with the door's existing lever. When an occupant rotates the door's lever, it not only retracts the door's latch, but the handle will also engage the unlocking mechanism of the present invention, the door lever engaging the unlocking mechanism. The door's lever follows the geometry of the cam thereby pushing the sliding bar of the unlocking mechanism thereby engaging a latch release. The latch release moves the locked lever of the door's deadbolt assembly and the deadbolt is retracted. When the door's lever is returned to its normal state, a spring pushes the sliding bar backward to the ready position. The latch release rotates to its ready position and the mechanism is ready for a subsequent activation.
