More Information
Summary:An on-demand power-operating door arrangement includes a supporting structure forming a passage, a door mounted to the supporting structure for closing the passage, and a power operator for operating the door. The power operator includes a motor, and a linkage operably connected to the motor and arranged to move the door to the passage-opening position. The door is manually swingable from a closed position to an open position independently of the linkage. The linkage and the door are returned from the door-opened position by respective springs, the spring which returns the door being weaker than the spring which returns the linkage.
