Abstract
Sectional upward acting doors used in vehicle cargo bodies are provided with multiple generally planar door panels which are interconnected by spaced apart hinge assemblies. At least selected intermediate hinge assemblies are provided with hinge pin receiving bosses to receive elongated hinge pins extending between adjacent hinge assemblies and secured thereto. The hinge pins preferably comprise elongated cylindrical rods which form hinge pins for adjacent hinge assemblies and extend between adjacent hinge assemblies to form a reinforcing member to minimize lateral deflection of the door panels.
