    Abstract: A door closer comprises a housing mountable to one of a door or a door frame, an arm having a first end pivotally attached to the housing and a second end connected to the other of the door or door frame, the arm being movable between a neutral door position and first and second open door positions up to 180 degrees from the neutral position in opposite directions, and opposing first and second racks movable relative to each other and relative to the housing. Each of the first and second racks has a first end adapted to engage a piston within the housing. The door closer further comprises a pinion within the housing pivotally connected to the arm first end and engaging teeth of the first and second racks, a piston having a first end adapted to engage the first end of the first and second racks, and a spring compressible by an opposite end of the piston. Movement of the arm from the neutral position to one of the first or second door open positions rotates the pinion and urges the first end of the first or second rack into engagement with the piston first end, the piston compressing the spring until the door reaches one of the first or second door open positions, and movement of the arm from the neutral position to the other of the first or second door open position rotates the pinion in an opposite direction and urges the first end of the other of the first or second rack into engagement with the piston first end, the piston compressing the spring until the door reaches the other of the first or second door open position.

    Abstract: A door closer, comprising a door closer housing mounted to one of a door frame or a door surface and a linkage arm for pivoting the door between open and closed positions. The linkage arm has a first and second end, the first end mounted to the other of the door frame or the door surface. The door closer includes a rotatable connector between the linkage arm and the door closer housing, the linkage arm second end engaging with the rotatable connector. The connector has a rotatable body portion and head protrusion substantially secured in a female receptor to transmit rotation about a longitudinal axis of the connector. One or both of the head protrusion or female receptor has a curved profile and is further movable with respect to the head protrusion to permit limited rotational misalignment of the linkage arm on any axis perpendicular to the connector longitudinal axis.

    Abstract: An apparatus for adjusting the force in a door operator or closer comprises an elongated housing and a spring therein connected to the door operator or closer. A spring collar is non-rotatable about the longitudinal axis of the housing and adapted to move linearly within the housing. A fixed adjusting screw extends along a longitudinal axis of the housing and the spring collar is slidable linearly along an outer surface of the adjusting screw. A nut is threadably engaged at a distal end of the adjusting screw and is rotatable about the longitudinal axis of the screw, the nut bearing on the spring collar during rotation. The spring collar bears on a distal end of the spring to vary the spring compression and thereby vary force applied by the door operator or closer. The housing has an opening in a sidewall through which the spring is visible, and the housing exterior surface includes markings indicating the degree of spring compression. An indicator is moveable along and visible from the exterior of the housing to indicate the compression of the spring.

    Abstract: A door closer with an electric motor-assisted closing feature, that may generate its own power to assist in closing, and controls the speed of opening and closing of the door during generation is disclosed. Embodiments of the present disclosure are realized by a motorized door closer that electrically creates a latch boost force for a closing door. The door closer includes a motor disposed to operatively connect to a door so that the door will be moved toward closed when the motor moves, and a position sensor to determine a position of the door. A processor is programmed to exert a closing force on the door in the latch boost region or when it otherwise detects that a motor assist is needed.

    Abstract: An electronic lock housing for the inside surface of a door with an opening therethrough has an interior portion for receiving electronic components for a door lock, a back portion with channels, a bracket, a plug, and a front portion. The back portion is meant for securing onto the door surface and has an opening meant for alignment with the door opening. The channels in the back portion permit air from the outside of the door to flow through the door opening and housing back opening to the inside of the door without passing through the housing interior. The bracket secures the back portion to the door and receives the plug to create an air-tight seal within the housing interior. The housing front portion is secured over the assembled back portion, bracket, and plug once they are installed to the door surface, fully encasing the electronic components.

    Abstract: A bracket is provided for use in installing door hardware on a support surface. The bracket comprises a rigid member having a longitudinal axis, a front surface, a substantially planar rear surface for engaging the support surface, and a peripheral edge extending between and joining the front and rear surfaces. A spirit bubble level is disposed on the rigid member such that the rigid member can be oriented relative to a horizontal line or a vertical line, the level having the bubble centered only when the level is horizontal or vertical. At least a portion of the peripheral edge of the rigid member provides a mounting surface for the door hardware when the rigid member is secured to the support surface.
