Telescoping type cover for truck beds and the like

摘要

An enclosure assembly enabling the selective covering of an area such as the bed of a pickup truck. The assembly includes a plurality of extendable collapsible cover section interconnected by an actuation system. The actuation system enables the rear cover section of the assembly to be pivoted to a collapsed or extended position by a pivoting structure having unique cam and leverage characteristics. The entire assembly can be selectively power operated or locked into position using a clutch mechanism associated with the actuation system. The actuation system can be powered by an electric motor or by a hand crank operating through bevel gears in case of a system failure.
