The plate compresses the gasket perimeter against a ridge on the first housing to form a seal around the circuit board.

Abstract: A door holder and release assembly that is adjustable to account for different differences between the door and where the door holder and release assembly will be installed (e.g., a wall, the floor, another support location). The door holder herein has a base member, a holder member, and a connector. The base member may be configured for operative coupling with a wall or a door. The holder member may be configured for operative coupling with a release assembly on the wall or the door opposite the base member. Moreover, the holder member may be configured to be telescopically operatively coupled with the base member through the connector to position the holder member at varied distances from base member to allow for the accommodation of varying distances between a wall and the door, as well as for minor adjustments that a user may want to make.

Abstract: A latch bolt with a bolt head that is removably mounted on a latch tail through the use of a bolt head adjustment mechanism. The bolt head adjustment mechanism may comprise one or more locking members (e.g., within the bolt head, the latch tail, and/or independent from the other components of the latch bolt) that allow the bolt head to be removed, rotated, and reassembled while the latch bolt is located within the case of the mortise lock. The bolt head may comprise an anti-friction latch that is configured to pivot within the flanges of the bolt head in a way that maintains contact between the anti-friction lock and the strike plate.

Abstract: A door system having a linkage assembly with a drive arm and an attendant arm coupled at the ends through a gear joint. The gear joint has drive teeth on an end of the drive arm and attendant teeth on an end of the attendant arm. The drive arm is coupled to a motor in the door system that is coupled to a door, or a door frame or a wall. The attendant arm is coupled to the opposite of the door, or the door frame or the wall to which the door system is coupled. When the door system is installed on the push side or the pull side of the door the drive arm and the attendant arm are parallel with the door and the upper door frame. During operation the motor transfers the torque from the motor through the gear joint to open the door.

Abstract: A door lock system may include an outer spindle operatively connected to a disc with a larger diameter than a diameter of the outer spindle. The disc may include an opening that slidingly receives a lock spindle along a lock axis configured to engage a lock body. The lock spindle and the spindle opening may have complementary shapes and sizes such that the lock spindle is rotationally coupled to the disc about the center axis. Torque may be transmitted from a handle to the disc and from the disc to the lock spindle via the opening.

Abstract: A door lock system includes a toolless handing assembly that selectively sets a handle in a left or right home position. The handing assembly may cooperate with a disc and a spring that biases the disc to a default position. The disc may be rotated in a first direction to set the disc in a first home position. A catch may engage the disc to retain the disc in the first home position. The catch may be released to return the disc to the default position and the disc may be rotated in a second direction to set the disc in a second home position, opposite the first home position.

Abstract: A lock portion of an electronic door lock system includes a first housing and a second housing secured to a backplate of the first housing. The second housing is secured to a first surface of the backplate and only accessible from a second surface of the backplate. One or more wires are secured to the second housing in a service loop and connected to an actuator within the second housing.

Abstract: A door lock system that adjusts to doors of different thicknesses. The door lock system may include self-adjusting spindles that engage and center a lock body in a door. The spindles may exert equal and opposing forces that center the lock body within the door and align the lock body with a latch.

Abstract: A tool for adjusting the backset of a latch bolt. The latch bolt includes a latch bolt and a tailpiece. A housing receives the latch bolt and includes a transversely extending protrusion. A casing slidably receives the housing such that the protrusion on the housing is received in a slot on the casing and an inner end of the tailpiece extends from the housing and casing. The casing is rotated relative to the housing to allow relative axial movement between the casing and the housing when transitioning between the first backset position and the second backset position. The tool includes a member defining a first slot for receiving the inner end of the tailpiece and a pair of second slots for receiving the pair of ears such that rotation of the tool rotates the tailpiece and the casing simultaneously.

Abstract: A door exit device may include a light source for indicating a status of the exit device. The light source may be capable of providing a first indication denoting that the exit device is in a first state (e.g., a dogged state) and a second indication denoting that the exit device is in a second state (e.g., an undogged state). Further, the exit device may include first and second parallel control systems capable of electronically controlling that status of the exit device. In some instances, a first parallel control system may supersede a second parallel control system.

Abstract: A latching device may include an actuator configured to actuate between an actuated state and an unactuated state, a first rod including a threaded end, and a first rod coupler operatively coupled to the actuator and the first rod and configured to transfer force between the actuator and the first rod. The first rod coupler may include a rod receptacle configured to rotate about a first axis and to at least partially receive and engaged the first rod. The first rod coupler may also include a rod adjuster rotatably coupled to the rod receptacle and configured to rotate about a second axis to rotate the rod receptacle about the first axis. The rotation of the rod receptacle may change the position of the first rod relative to the actuator.
