Manual tarp enclosing system for flat bed trucks

摘要

A manual tarp enclosing system is disclosed for enclosing flat bed trailers which has an elongate track on each side and a plurality of U-shaped bows bridging the bed with one of the legs of the bow received in the track on each side of the bed for movement longitudinally in the track means. A cable positioning system for moving and positioning the bow is provided which comprises a closed loop of cable which extends along one side, across the width and down the other side of the bed as parallel double strands. A first bow is secured to one of the cable strands running parallel each of the tracks whereby on manually pulling on the loop of the cable, the first bow is moved towards the front or rear of the bed. A cover is secured to the first bow and at successive intervals to successive of the bows. On drawing the first bow, the cover extends or collapses in an accordion-like manner.
