Abstract: A cover assembly for the rear compartment of a pickup truck consisting of three rectangular panels arranged longitudinally along the top of the compartment. The center panel is substantially fixed and the side panels are pivotally attached along their inside edges to the outside edges of the center panel and are moveable from a closed to an open position. A flange extends beyond the perimeter of the cover and overlaps the top surfaces of the truck bed providing support for the cover. A horizontal member is attached to the rear edge of the center panel and in combination with a vertical member at each end provides support for the rear of the cover when the tailgate is open.
