APPARATUS AND METHOD FOR A ROTATABLE TAILGATE ASSEMBLY HAVING SERVICE AND OUT-OF-SERVICE POSITIONS

摘要

A subassembly is provided for the pivotal body of a heavy-duty truck comprising a tailgate assembly which rotates between service and out-of-service positions in order to provide a truck body having a dual volume capacity. The tailgate assembly includes opposing side beams attached at their first ends to a tailgate which forms a back wall of the truck body when the assembly is in its service position. Pivot means couple the opposing side beams to the opposing side walls of the truck body such that the tailgate assembly may be rotated about an axis of rotation between its service and out-of-service positions. Means are provided for rotating the tailgate assembly about its axis of rotation wherein the rotating means advantageously utilizes the changing position of the center of gravity of the tailgate assembly as it rotates between positions. 39-121
