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 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.
Abstract:
An automatic sliding door in which a main drive moves at least one door panel to open and closed positions. An electromagnetic clutch is located between the main drive and the door panel for the purpose of disconnecting the panel from the drive and to open the door in event of a power failure. An auxiliary drive is connected to the door panel and stores energy received when the door panel is in a closed position, so as to drive the door to the open position when the clutch disconnects the main drive from the door panel in event of power failure. The auxiliary drive has a rubber cable actuated always with the door so that the auxiliary drive can be tested with every movement of the door panel.
Abstract:
A drive suitable for a door or gate operator mechanism has a motor (1) and a gear box (5). The gear box (5) has a drive disengaging means (29) therein which can be pulled by a chord (7) to effect drive engagement of the motor (1) with the gear box (5). When the chord (7) is next pulled drive disengagement of the motor (1) with the gear box (5) is provided. The arrangement permits a door or gate which is driven by the operator to be manually opened in the event of power failure. The mechanical advantage of the gearbox (5) and the motor (1) on the door or gate is such that the gate cannot be manually opened without the drive being disengaged.
