Abstract
A spring assisted overhead door is disclosed. An overhead door is movable between an open and a closed position. In the open position the overhead door is in a horizontal orientation and rests on a track that is also horizontal. Weight of the door in this position may be insufficient to initiate downward movement of the overhead door. A spring is used to urge the overhead door along the track until a release point at which point the overhead door is at least partially on a downwardly oriented portion of the track where gravity can pull the overhead door along the track.
