Abstract: A motor for driving a garage door is controlled by a control unit, which counts the time required for the garage door to move between an upper limit switch and a lower limit switch. The control unit sets a comparison reference time on the basis of the time thus counted, and controls the motor in such a manner that the motor driving does not continue for a period of time longer than the comparison reference time.

Abstract: 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.

Abstract: A push-pull chain garage door operator system includes a drive module and an elongated guide rail for a push-pull chain connected to a carriage assembly mounted on the guide rail. The chain is engaged with a sprocket mounted on a generally rectangular plate-like molded plastic support member which includes a serpentine idle chain storage slot formed therein. The support member is releasably connected to a stamped metal frame plate for covering the storage slot and supporting the drive module. The bottomwall of the support member supports a right angle speed reduction drive unit connected to a drive motor retained in a cradle formed by an integral boss on the support member. The motor and a starting capacitor therefor are retained in respective cradle portions of the boss by a removable retaining strap. A control circuit board is mounted on the underside of the support member and a two-part shroud for the operator mechanism is releasably secured to the frame plate.
