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.

Door closer

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.

Mounting bracket

A door control apparatus and methods for controlling a door motion device for a hinged door and, optionally, illuminating a designated area on the floor. During the time the designated area is illuminated, a person can expect that the door will not close. The door control apparatus may include control circuitry, and a sensor, and optionally a light emitter and/or a sound emitter. The sensor detects a person proximate to the door and signals the control circuitry upon a detection event. The light emitter is also connected to the control circuitry. Upon a detection event, the control circuitry signals the light emitter to produce light and signals the door motion device to hold the door open. The light emitter directs light to form an image on the floor in the designated area. The light emitter may be, for example, a laser generator or a light emitting diode lamp.

Door control apparatus

A drive mechanism for a door operator comprises a drive member and a driven member. The drive member is adapted to be operably connected between a motor assembly for rotating the drive member and a door closer assembly rotating with the driven member. The drive member and the driven member both include a protrusion. The driven member protrusion moves in the free space defined by driving surfaces of the drive member protrusion. Rotation of the drive member from a first angular orientation to a second angular orientation causes rotation of the driven member for powered opening of the door. The driven member protrusion moves in the free space without engaging the protrusion surfaces when the door is opened manually and allowed to close.

Door operator

A door operator for selectively opening and closing a side hinge door. The door operator may include a motor with a drive shaft, an operator arm assembly, a door position sensor, and a controller. The operator arm assembly may include an output shaft operatively coupled to the drive shaft, an operator arm, and a clutch assembly mounted to the output shaft. The door position sensor, which may be electro-magnetic, signals the controller when the door is not closed. If the door has been manually pushed open, the controller signals the motor to rotate the drive shaft in the closing direction. In automatic mode, the output shaft and the operator arm are operatively engaged, but manual force to open the door overcomes static friction between the operator arm and friction discs in the clutch assembly, operatively disengaging the operator arm and output shaft until the manual force is removed.

A door operator with an electrical back check feature is disclosed. Embodiments of the present invention are realized by a motorized door operator that electrically creates a back check force for an opening door. The door operator simulates the back check normally created by hydraulic means in convention door closers, but without the use of pistons, springs or hydraulic fluid. The door operator includes a motor disposed to operatively connect to a door so that the door will open 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 back check region. In some embodiments, the closing force is exerted by injecting a voltage into the electric motor of the door operator.

A photoluminescent member is provided for an exit device. The photoluminescent member comprises a housing member for mounting to the exterior surface of the exit device. The housing member includes a photoluminescent portion for being energized by exposure to an ambient light source and operable to automatically emit visible light photoluminescently for a substantial period of time in low ambient light or dark conditions and without being energized by an electrical current so that the photoluminescent portion provides illumination to identify the exit device in the low ambient light or dark conditions for providing a visual cue directing a person to a location of the exit device.

Photoluminescent exit device

A drive mechanism is provided for a door operator, comprising a drive member and a driven member. The drive member includes a protrusion, the edges of the protrusion forming first and second driving surfaces which define a free space of at least about 90&#xb0; there between. The driven member includes a protrusion, the sides of the protrusion form a first and a second driven surface, respectively. The drive member is adapted to be operably connected to between a motor assembly for rotating the drive member and a door closer assembly rotating with the driven member. The drive member and the driven member are disposed for relative rotation in substantially the same plane such that the driven member protrusion moves in the free space defined by the driving surfaces of the drive member protrusion. Rotation of the drive member from a first angular orientation to a second angular orientation in a direction toward an adjacent driven surface causes rotation of the driven member for powered opening of the door from the closed position to the open position. The driven member protrusion moves in the free space without engaging the protrusion surfaces when the door is opened manually from the closed position and allowed to close.
