High-speed sectional door

An overhead sectional door for closing an opening when in a closed position, the door comprising:

• a plurality of panels each arranged in a generally vertical orientation and stacked one upon another when in the closed position;
• wherein each of the plurality of panels is in a generally horizontal orientation and arranged in a stacked configuration when in an open position exposing the opening;
• a track system operable to guide the plurality of panels to and from the closed position and the open position;
• and
• the track system further comprising a plurality of tracks each of which is associated with and guides one of the panels of the plurality of panels;
• wherein each track of the plurality of tracks has one of the panels of the plurality of panels dedicated thereto;
• wherein each of the panels of the plurality of panels has one of the tracks of the plurality of tracks dedicated thereto;
• wherein each track of the plurality of tracks further comprises a dedicated vertical track, a dedicated horizontal track and a dedicated transition track to guide movement of one of the panels of the plurality of panels to and from the closed position and the open position.

An overhead sectional door for closing an opening when in a closed position, the door comprising:

• a plurality of panels each arranged in a generally vertical orientation and stacked one upon another when in the closed position;
• wherein the plurality of panels is positioned above the opening when in an open position exposing the opening;
• a track system operable to guide the plurality of panels to and from the closed position and the open position;
• and
• a counterbalance system to assist movement of the plurality of panels to and from the open and closed positions, the counterbalance system further comprising one of the following:
• compression springs, extension springs, torsion springs and counterbalance weights.

An overhead sectional door for closing an opening when in a closed position, the door comprising:

• a plurality of panels each arranged in a generally vertical orientation and stacked one upon another when in the closed position;
• wherein the plurality of panels is positioned above the opening when in an open position exposing the opening;
• a track system operable to guide the plurality of panels to and from the closed position and the open position;
• and
• a plurality of rollers each mounted to one of the plurality of panels for movement within the track system;
• wherein the plurality of rollers further comprises at least one stabilizing roller having a stabilizing roller axis of rotation and at least one load-bearing roller having a load-bearing roller axis of rotation, wherein each of the at least one stabilizing roller and the at least one load-bearing roller are mounted to each one of the plurality of panels, wherein the stabilizing roller axis of rotation is generally perpendicular to the load-bearing axis of rotation.
