发明名称 ROLL-UP TARP FOR TRAILERS
摘要 <p>A canvas tarpaulin having dimensions sufficient to cover the top of an open truck box has one edge affixed to one longitundinal edge of the truck box top. The opposite edge of the tarpaulin is affixed to a tube which extends for the lenth of the box. The rear of the tube contains an extension attached to a universal joint. A crank handle is also attached to the joint so that the tube can be rolled transversely across the top to roll up the tarpulin thereon. A downward cantilevered lip is attached to the opposite longitudinal edge of the box top. When the tarp is unrolled, the tube rolls over a free edge of the lip and can be wound in the opposite direction rolling up a small portion of the tarpaulin under the free edge. The crank handle is then moved against the rear of the truck body thus locking the universal joint thereby holding the tarp tightly upon the box top. The crank handle is then secured against the rear of the box.</p>
