Abstract:
1. For use with a load bed cover approximately cab high, raisable at the rear from a closed position to an open position on a load bed of a vehicle having a passenger cab immediately forward of the load bed: A 4-bar hinge comprising a short forward arm and a long rearward arm, each pivotally attached toward an upper end to an upper link means and pivotally attached toward a lower end to a lower link means to create a closed linkage of quadrilateral form; wherein the upper link means is fixedly attachable to a cab high load bed cover mounting rail, and the lower link means is fixedly attachable to a load bed side wall so that the short forward and long rearward arms will be pivotally attached to the upper link means in proximity to the cap mounting rails and will be pivotally attached to the lower link means in proximity to upper edges of the load bed side walls; wherein longitudinal spacing of the rearward arm lower pivot axis from the forward arm lower pivot axis exceeds spacing of the rearward arm lower pivot axis from the rearward arm upper pivot axis; and wherein, as the cover is raised to a fully open position, the short forward arm upper pivot rotates over the short forward arm lower pivot beyond a plane through the forward arm lower pivot axis and perpendicular to a load bed side wall upper surfaces in side view.
