Abstract:
A door comprises a frame, first and second outer skins, and first and second stiffeners. The first and second outer skins are respectively connected to first and second sides of the frame, and the first and second stiffeners are positioned between the first and second outer skins and are attached to the frame. The first stiffener is connected to the first side of the frame, and the second stiffener is connected to the second side of the frame. The first and second outer skins are respectively connected to the first and second stiffeners at positions adjacent the frame. The first and second stiffeners are joined together within an area defined by the frame, and the first and second stiffeners are joined together along a plane approximately equidistant from the first and second outer skins. The door also includes a window.
