Abstract: A truck body includes two opposing side wall panels, a roof panel, and a floor panel, at least two joints of which are connected by hinges. A first hinge connects one of the side panels to the roof panel. A second hinge connects a second one of the side panels to the floor panel. Thus, the two sides, roof and floor may form an open-ended rectangular box when assembled, but they may lie flat when disassembled. The hinges may include one or more rotating hinges, slip hinges or other types of hinge.

Abstract: A hinge, such as a truck body door hinge, includes a first mounting member, a second mounting member, a first connecting member that is pivotably connected to the first and second mounting members, and a second connecting member that is also pivotably connected to the first and second mounting members. The first and second connecting members are pivotally connected to each other at an axial position.

Abstract: A door seal according to an embodiment of the invention includes a rubber seal and a mechanical seal. The rubber seal is a compressible, hollow body having a D-shaped longitudinal cross-section, affixed to the inner surface of a door which is adapted for contacting an outer surface of an associated door frame when in a closed position. The seal extends for substantially the entire perimeter of the door. A mechanical stop, extending from the door frame, engages said door, when in a closed position, to form a channel for directing water away from an opening formed by the door frame.
