ABSTRACT:
A generally horizontal load bed construction including upstanding opposite side walls is provided together with an elongated flexible cover for extension and retraction over the upper edges of the side walls of the load bed. One end of the load bed is provided with a winding member to which one end of the flexible cover is secured for winding thereon and the opposite side walls of the load bed include elongated generally horizontal tracks extending longitudinally thereof and including downwardly directed opposite end portions. A pair of upstanding support arms are secured at their upper ends to the extendible and retractable end of the cover and the lower end of each support arm includes a pair of follower members spaced on opposite sides of the support arm and engaged with longitudinally spaced portions of the corresponding track or track member. When the support arms are disposed at the end of the load bed from which the winding member is journaled, the support arms are inclined upwardly and outwardly of that end of the load bed. As the support arms move away from that end of the load bed they are upwardly shifted toward the remote end of the load bed and thereafter swing to a substantially vertical position for continued movement along the load bed in a horizontal direction. Then, as the support arms approach the end of the load bed remote from the winding member and move onto the corresponding downwardly inclined ends of the track members, the support arms are swung past the upright center positions to positions inclined upwardly and outwardly of the end of the load bed remote from the winding member after which the support arms then move in a downwardly inclined direction to their limit positions of movement away from the winding member.
