  • Patent number: 4265479
    Abstract: A watertight cover for the open bed of a pickup truck has continuous flexible sheathing supported on a collapsible frame and pivot arms swingable with the frame for automatically and positively folding the end section of the cover when the frame is collapsed. The collapsible nature of the frame renders the cover shiftable transversely of the truck bed from a normal extended bed-enclosing position to a retracted position along one side of the bed for providing easy access thereinto. In one embodiment, the cover is provided with remote-actuation mechanism including a central torque shaft operably coupled with the frame for collapsing and extending the latter in response to rotation of the shaft in the appropriate direction.
