ABSTRACT:
The invention comprises a truck box cover device. The device has a rod with a rectangular tarp attached to the rod at its one end and attached to the edge of a truck box at its other end. The tarp is rolled onto the rod toward the edge of the truck box where the outer end of the tarp is attached to uncover the open top of a truck box, and is unrolled in the opposite direction to cover the truck box. A pair of ropes are attached to the outer ends of the rod at one end of the ropes. The outer ends of the ropes are attached to springs and the springs are attached to the sides of the truck box. As the tarp is unrolled the ropes are wound onto the rod. The springs act to place tension on the rope and clearly place tension on the rods and thereby urge the tarp in a straight line toward an unrolled position and thereby act to keep the tarp straight.
