Abstract
A retractable cover system that folds into a compact storage position which can also be easily removed from the pickup truck box. The inventive device includes a pair of opposing rails attachable to the upper portions of a box of a pickup truck, a front member extending between the pair of rails, a mounting bracket attached to each of the rails for securing the rails within the box, and a cover structure movably positioned between the rails. The cover structure is comprised of a plurality of panels pivotally attached to one another having a set of first rollers and a set of second rollers on opposing sides of the panels that rotatably travel within the rails. A pair of opposing ramp structures are attached to the opposing rails for allowing the set of first rollers to travel downwardly from the rails. The first rollers and the second rollers are preferably staggered with respect to one another upon each side of the panels thereby allowing the second rollers to remain upon the rails while the first rollers travel downwardly and upwardly upon the ramp structures.
