  • Mechanical arm system for opening a door
    Patent number: 8074401
    Abstract: A mechanical arm system for opening a door includes an actuator assembly having an output shaft and an arm driven by the output shaft so as to move the door from a closed position toward an open position. The arm is free from contact with the door when the door moves from the open position to the closed position. The actuator assembly is mounted to a support member adjacent the door. The arm extends between the output shaft and the door. The arm may be moveable between a position in which the arm contacts the door in the open position and a retracted position in which the arm is free from contact with the door in the closed position. The arm may be moved to the retracted position before the door reaches the open position so as to abort the opening of the door.
