ABSTRACT:
An improved roll-up truck cover assembly is provided for use on trucks having a rectangular open truck body carrying gravel, loose dirt and the like. The roll-up truck cover assembly comprises a rectangular flexible top cover attached at one end to the front wall of the truck body and at the other end to a take-up roll including a biasing member tending to rotate the roll in a take-up operation. A pair of elongated swinging arms are provided one on each opposite side wall of the truck body. The swinging arms may comprise, for example, a first or upper elongated tube or rod rotatably connected at one end to the take-up roll. The first or upper elongated tube or rod is telescopically and retractably mounted at its other end within a second or lower larger diameter tube pivotally mounted to a lower end portion of one of the side walls of the truck body. A roller and an elongated roller guide track are provided for each swinging arm on each opposite side wall of the truck body. Each roller is rotatably mounted onto a shaft which is attached to the first or upper tube of each swinging arm and are moveably engaged within each of the guide tracks. Means are provided for pivotally moving the swinging arms along the opposite side walls of the truck body in an arch-like manner from one to the other opposite end of the truck. The take-up roll and top cover travel along with the swinging arms and the cover is unwound from the take-up roll in one direction covering the open end of the truck body and then wound onto the take-up roll in the opposite direction during the take-up operation. The rollers move along the guide tracks in a straight longitudinal path causing the first or upper tube or rod to retract within the second or lower tube, keeping to a minimum the height to which the take-up roll and top cover can be raised above the truck body.
