Door positioning system and door assembly

A folding panel door assembly, comprising:

• a doorway defined by a frame, the doorway having a height between a header and a threshold and parallel to a vertical axis, a length between a first jamb and a second jamb and parallel to a longitudinal axis, the vertical axis and the longitudinal axis defining a vertical plane of the doorway between the first jamb and the second jamb, and a depth parallel to a lateral axis that is perpendicular to the vertical plane;
• a door assembly comprising a folding panel door and an extension, the folding panel door having a first panel moveably attached to a second panel and the extension having a top wall, an inside edge and outside edge parallel to the vertical axis, and an extension length between an inside edge and an outside edge;
• a first pivot connector having a first vertical pivot axis attaching the extension to the frame with the inside edge adjacent to the first jamb;
• and
• a second pivot connector having a second vertical pivot axis attaching the extension to the first panel:
• wherein the door assembly is moveable between a full closed position, a first open position, a second open position, and a fully open position;
• wherein in the full closed position the extension length, the first panel, and the second panel are coaxial and parallel to the vertical plane;
• wherein in the first open position the extension length is generally parallel to the vertical plane, and the first panel and the second panel are generally perpendicular to the extension length and generally parallel to one another and to the lateral axis;
• wherein in the second open position the extension length, the first panel, and the second panel are generally parallel to the lateral axis and to each other;
• and
• wherein in the fully open position the extension length is generally parallel to the lateral axis, the first panel and the second panel are generally perpendicular to the lateral axis and the extension length, and the extension is located between the folding panel door and the doorway.
