Automatic garage door opener

A garage door opener is provided with a drive mechanism formed by a chain that runs in a track. The track is mounted on the platform of a mounting support that is hinged to the vehicle entry wall of a garage directly above the garage door opening. The track includes a track opening directed straight out from the vehicle entry wall. The track extends in a curve from the track opening toward the vehicle entry wall, along a first proximal straight section that lies parallel to the vehicle entry wall, around a one hundred eight degree bend, and along another distal straight section that is located parallel to and spaced from the first, proximal section. The chain is formed with large links having flat upper and lower plates. Each link has a hinged side and an unhinged side and the links are joined together at their corners along their hinged sides. The chain can only be bent in an arc that is concave inwardly toward the hinged sides of the links. A reversible drive mechanism drives the chain so that as the garage door is opened, the chain links emanate in straight linear alignment with each other from the track opening and function as a push rod that forces the top of the garage door inwardly toward the interior of the garage. When the garage door is closed, the links of the chain will flex about their corner connections and thereby follow the chain track on the platform. As the garage door approaches a closed position, a lift mechanism is actuated that rotates the platform upwardly through a small arc to allow the top of the garage door to pass therebeneath.
