Abstract
Abstract A channel-shaped track extends along the upper edge of each side of a truck box, the channel-shaped configuration providing an upwardly facing slot. The tracks contain and guide a plurality of shoe mechanisms each comprised of a hinged pair of vertical panels. The laterally spaced ends of the bows, the flexible canopy being placed over the bows, are supported by the shoe mechanisms, there being one shoe mechanism for each bow end and the bow end functioning as a hinge pin in each instance. The lower marginal portions of the canopy are anchored to these panels. The rear portions of the tracks maintain the hinged panels in a straight line relationship, whereas the forward portions of the tracks permit the inward pivoting of the panels as the canopy is collapsed or retracted beneath a protective hood. The hood and sections of the tracks therebeneath can pivot upwardly to permit removal of the sides of the truck box. The rear of the truck box is equipped with a hinged tail piece that is automatically raised when the canopy is fully extended or expanded. Further, the tracks are formed so that moisture will not enter the interior of the truck box.
