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.
