ABSTRACT:
A roll tarp system for covering the open top of a truck semi-trailer, characterized by the use of a novel roll bar construction in combination with an adjustable toggle clamp for locking the tarp in its closed unrolled condition. A rectangular tarp or cover member is connected at one longitudinal edge with the upper edge of one longitudinal side wall of the container. A roll bar is connected with the other longitudinal edge of the tarp via a first longitudinally extending peripheral groove contained in the roll bar. The roll bar includes at least one longitudinally slidable and positionable fastening device arranged in a second groove diametrically opposite the first groove, a cable member being fastened at one end to the fastening device. The other end of the cable is connected to the adjustable toggle clamp which is mounted on the external surface of the other longitudinal side wall of the container below and vertically spaced from the roll bar when the tarp is in the unrolled condition covering the opening in the top of the container. When the clamp is operated, it tensions the cable and the tarp and retains the tarp in the unrolled closed condition. The roll bar may have a generally circular outer cross-sectional configuration, or a "figure-8" cross-section.
