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: The sudden unrolling of an motor driven overhead door is a hazardous occurrence. The invention provides a method of detection and warning of a damaged counterbalance mechanism or other defect in the door lifting assembly. The amperage readings of the drive motor are observed to increase between 5% and 30%, above that of normal operation when the function of the counterbalance assembly or similar drive assembly component is compromised. The method is reduced to practice as a number of alternative electronic circuits which are placed between the line power source and the drive motor. The circuit senses the motor amperage draw and compares the reading with a preset threshold value. Upon the sensed value exceeding the threshold value, a warning is broadcast. This method alerts one of undue strain on a damaged lifting assembly prior to its catastrophic failure.

Abstract: A door controlling device for opening and closing a door in a wall has a first arm, one end of which is mounted to the wall and the other end of which is pivotally attached to the second end of a second arm. The first end of the second arm is pivotally attached to the top of a door and is adapted for rotation about a horizontal axis at the first end thereof. An electric motor attached to the device has a shaft which drives a gear train, and an output shaft of the gear train is connected to the input end of an electrically operated clutch. The output shaft of the clutch is connected to the first end of one of the arms such that upon the simultaneous engagement of the clutch and the energizing of the motor, that arm will be rotated about the horizontal axis at the first end and will cause the door to be opened or closed. Also, a current measuring device for determining whether the motor is drawing on excessive amount of electric current, a door open sensor for generating a signal when the door is in a fully opened position, and a door closed sensor for generating a signal when the door is in a fully closed position are all connected to a computer to control the opening and closing of a door.

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 keyless system for quickly and conveniently securing the storage area of a delivery type truck against unauthorized entry and theft while the driver is away from the truck making a delivery or pickup. In reaching a delivery point or approaching the truck after a pickup, the driver actuates a portable transmitter to generate a wireless signal which is received and processed by a receiver within the truck and which unlocks and opens the access door to the storage area. Upon exit from the storage area after selecting or depositing a package, the driver simply taps a switch located in the cab of the truck to generate a signal which causes the access door to close and lock automatically. Securement of the rear cargo loading door also is controlled by use of the portable transmitter to generate a further signal for operating the loading door lock.

Abstract: A compartment confining construction comprises an opening and a closure unit movably mounted on the compartment confining construction for movement between a closing position and a fully opened position with respect to the opening. A fluid-based positioning unit is connected to both the compartment confining construction and the closure unit, the fluid-based positioning unit having two working chambers interconnected by at least one flow path, a movement of the closure unit corresponding to a flow of fluid from one chamber to another through the at least one flow path. A fluid flow control device is provided for controlling the flow of fluid through the at least one flow path and thereby controlling the movement of the closure unit. The fluid flow control device is actuatable by an electric actuating device. The flow of liquid occurs in response to movement of the closure unit when the closure unit is moved by an external force.

Abstract: A van door slidable in tracks (16, 18 and 20). An operating module is mounted inside the van adjacent center track 18. A front cable attached to drive pulley (144) extends through guide assembly (54) to hinge and roller assemble (26). A rear cable attached to drive pulley (136) extends through guide assembly (56) to hinge and roller assembly (26). The drive pulleys (136 and 144) each have a large diameter spiral cable groove (164), a small diameter cable groove (208) and a transition cable groove (210). A motor rotates the drive pulleys. The small diameter cable grooves drive the door when the door is in the forward portion of the tracks. The large diameter spiral cable grooves drive the door when the door is in the center and rear portions of the track. Fixed idler rollers (226 and 254) are positioned relative to the cable drive pulleys to insure that the total cable in the continuous cable loop is substantially the same when the cable is driven by the small diameter cable grooves as when the cable is driven by the large diameter spiral cable grooves. A cable tension system (220) maintains cable tension. A slack cable take-up pulley (174) on the drive pulley (136) takes up slack cable to set cable tension and is then locked in position.
