ABSTRACT:
A modular cargo system for a truck-style vehicle includes a cargo box having demountable pivot points on opposite sides near the front and bottom. Translating drives move along opposite sides of the truck bed and carry translating pivot blocks. Each translating pivot block has a pivotally-connected dual-link mechanism also pivotally connectable at the opposite ends to the demountable pivot points on the cargo box. The dual link mechanisms are of a length to allow the cargo box to sit on the ground behind the truck bed with the translating blocks moved near the tail end of the truck bed. By moving the translating blocks toward the cab end of the truck bed, the dual-link mechanisms articulate at an approximate end point, and the lower links are adapted to guide over the tail end of the truck bed while raising the front end of the cargo box in a manner that the front end of the cargo box clears the tail end of the truck bed. Further movement toward the cab end pulls the cargo box up into the truck bed. Mechanisms are provided for folding the link mechanisms so the cargo box may be fully boarded, and for ejecting the cargo box in several different ways.
