    Abstract: A power-off door closing device of fire proof rolling door in which the rolling door slides down to close by its own weight under abnormal power-off condition by brake-releasing action or by brake-applied action of a braking pin actuated by a energized solenoid, through successive movement of the first end of a sliding lever of a solenoid with a bent arm, a clamp member and a brake actuating rod. This device can be easily changed into non-failsafe door closing fire proof type with original configurations wherein the solenoid is reverse located so that the brake-released action caused by an energized solenoid or the brake-applied action under abnormal power-off condition applies. A reserved power supply temporarily energizes the solenoid to maintain a temporary brake-releasing under abnormal power-off condition, to enable the rolling door sliding down to close by its own weight.

    Abstract: A method and apparatus according to various aspects of the present invention is configured to automatically reset a rollable fire door curtain in the raised position. In one embodiment, a brake is coupled to a rolling fire door axle by an electromechanical clutch. The fire door is pre-disposed to unroll and close the opening, however, the brake prevents the door from unrolling. When a switch, a signal, or a fusible link indicates that the fire door should close, an electromechanical circuit board sends an electrical signal to an electromechanical clutch which opens the clutch. With the clutch open, the brake is no longer coupled to the fire door and the door closes. When the switch or signal is reversed, the clutch closes, re-coupling the fire door axle to the brake. The brake allows input rotation in both directions, but prevents the rolling door from closing under its own weight. Therefore, upon raising the curtain, the fire door is automatically reset and ready to close in the event of a fire.

    Abstract: A time delay release mechanism has a brake actuator including an actuation member movable between engaged and released positions. The actuation member, when in the engaged position, operatively engages a fire barrier for preventing closure thereof. The actuation member, when in the released position, is operatively disengaged from the fire barrier such that the release mechanism does not prevent closure thereof. A timer includes a magnet which is powered by voltage applied to a capacitor. The magnet is, in turn, connected to the actuator member. When power is interrupted, the capacitor disengages for a predetermined time period. At the conclusion of the time period the magnet releases the actuator which, in turn, releases the brake and causes the fire barrier to close.

    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.
