ABSTRACT:
A tri-fold door system including a pair of spaced uprights defining a door opening, and a door including three vertically oriented panels namely, a distal panel, an intermediate panel and a proximal panel. These panels are hinged together for movement relative to one another from a door closed position wherein the panels are in the plane of the door opening to a door open position wherein the panels lie folded in close juxtaposition to each other. The proximal panel is hinged to a first one of the uprights defining the door opening. A track-way extends from the other one of the uprights part-way toward the first upright and is adapted to receive and guide the distal panel in a path lying in the plane of the door opening away from or toward the other one of the uprights as the door is being opened or closed respectively. At the same time the remaining two panels pivot relative to one another between positions which are co-planar relative to each other and folded positions in close juxtaposition with each other.
