摘要

A building including an upper wall portion and a lower wall portion and a bi-fold door assembly mounted within an opening therein. The wall portions have front surfaces facing outwardly of the building and the upper wall portion is disposed in a plane intersecting the plane defined by the lower wall portion. The upper wall portion is sloped downwardly and outwardly of the top thereof to a position overlying the lower wall portion and the plane defined by the lower wall portion is a generally vertical plane with the top of the upper wall portion being disposed in or near the generally vertical plane. The bi-fold door assembly is movable between raised and lowered positions within the opening in the wall portions and includes an upper door section and a lower door section. The upper door section is hinged to the lower door section with the door sections having front surfaces facing outwardly of the building and rear surfaces facing inwardly of the building. The upper door section is disposed in a plane intersecting the plane defined by the lower door section in the lowered position of the door assembly. The upper door section is sloped downwardly and outwardly of the top thereof to a position overlying the lower door section in the lowered position of the door and the plane defined by the lower door section is a generally vertical plane with the top of the upper door section being disposed in or near the generally vertical plane in the lowered position of the door assembly. Additionally, the upper wall portion and upper door section are coplanar and the lower wall portion and lower door section are coplanar in the lowered position of the door assembly.
