    Abstract: The present invention is provided with a mechanism for controlling the opening and closing of a door comprising a speed reduction means for reducing a rotational speed. A high speed shaft is connected to the speed reduction means and is connectable to a means for rotating the input shaft, and a low speed output shaft is connected to the speed reduction means. A governor is mounted on the input shaft for limiting the rotational speed thereof, to also regulate the rotational speed of the output shaft. A brake is provided for preventing rotation of the output shaft, and a self-closing mechanism is operatively connected to the door. The self-closing mechanism is adapted for storing energy when the door is opened to an open position, and a connecting means operatively connects the output shaft to the self-closing mechanism. A releasing means is provided for releasing the brake to permit rotation of the output shaft under the urging of the self-closing mechanism whereby the self-closing mechanism releases the energy stored therein so as to close the door to a closed position when the brake is released by the releasing means.

    Abstract: A resettable fail-safe fire door release mechanism which allows normal powered operation of a fire door is disclosed. A solenoid having a first open state in the absence of an applied electric current and a second closed state in the presence of an applied electric current is incorporated into the motor-operator unit of an overhead door. Brake actuator utilizes the spring force of a normally disengaged brake to keep the brake actuator in a first position. The plunger of the solenoid acts through the brake actuator in opposition to the spring so that energizing the solenoid overcomes the force of the spring, moving the brake actuator, and engaging the brake; deenergizing the solenoid causes the spring to again disengage the brake. A normally closed switch having a mechanical actuator is wired in series with the solenoid. The melting of a fusible link releases a spring loaded plunger which depresses the actuator opening the switch. A cable having one end connected to the actuator of the switch and the other end external to the case of the motor-operator allows manual opening of the switch and hence closing of the door.

    Abstract: A retraction device for automatically closing a panel, such as a door or window, after the panel has been opened. The retraction device includes a drum, a coiled spring power assembly for driving the drum, a centrifugal brake for controlling the power assembly and the drum to eliminate slamming of the panel during closing, and a gear train transmission assembly to connect the power assembly and the centrifugal brake. In one embodiment, the drum is a spool which carries a cable to connect the panel to the retraction device. In another embodiment, the drum has a rim which frictionally engages a frame supporting the panel. The centrifugal brake is adjustable to take into account a wide range of panel sizes and frictional conditions. This adjustment can be made through an aperture in the device's housing for quick and easy on-site installation. A one-way clutch mechanism is coupled between the power assembly and the brake to actuate the brake only when the panel is being retracted. This clutch mechanism is formed by two members, each of which is integrally molded of plastic.
