Abstract: A door panel latching apparatus including first and second elongated rods telescoped together for relative sliding movement. The first rod is mounted to the door with a free end for latching near an upper door edge and free to rotate about its longitudinal axis but is prevented from moving longitudinally. The second rod is mounted to the door with a free end for latching near a lower door edge and free to rotate about its longitudinal axis and to move along its longitudinal axis. A handle is connected to the rods by a linkage for longitudinally moving the second rod when the handle is rotated about an axis perpendicular to the longitudinal axis of the rods and for rotating both rods when the handle is rotated about an axis which is coincident with the longitudinal axes of the rods.

Abstract: A truck or trailer body construction is disclosed in which the front portion is shaped to reduce dynamic drag, which has a maximum interior capacity, and in which the front corners, which are particularly subject to damage, can be readily replaced. Provisions are also made for diagonally mounted lights and for relief of air pressure at the upper part of the front corners.

Abstract: A latch mechanism for walk ramps for truck bodies and the like is disclosed which includes, on each side of the walk ramp at its rear end and for retaining the walk ramp in its stored position usually below the floor of the truck body, locking handles carried on vertical pivots and provided with latch fingers which are normally resiliently urged to locked positions but movable to release positions to permit the withdrawal of the walk ramp for use.

Abstract: An air cargo container is disclosed of metallic construction which is light in weight, yet sturdy and which has structure for overcoming problems which have been encountered with cargo containers heretofore available and with particular reference to hold-down or restraint pockets, fork lift pockets and floor construction and which complies with present government and other applicable standards.

Abstract: A ramp and ramp carrier for trucks and the like is disclosed in which the truck body is provided with long rails comprising channels facing inwardly and which carry the cross members and truck floor, the long rails being supported and secured to the spaced parallel truck frame rails, with interposed spacers of wood, the securing elements being exteriorly of the channels and truck frame to avoid interior interference with the ramp, the ramp being carried between and by the long rails with provisions for retention and, upon withdrawal for use, with the outer end on the ground having members for hooking over a rear plate on the body.

Abstract: A transverse interlock floor for the bodies of trucks, vans, trailers and other vehicles is disclosed in which extruded transverse floor panels are employed extending from side to side in the body with edge interlocks between adjoining panels, and with stiffening braces on the undersides of the panels, the panels being secured to and supported from below on transverse I-beams of the body and with intermediate stiffening braces if desired, the transverse I-beams being supported on the longitudinal I-beams or frame members of the body which latter are secured to the longitudinal frame channels of the truck chassis.
