  • Patent number: 5931521
    Abstract: A folding cover for a pickup truck bed includes an improved adjustable front hinge support for mounting the cover that permits the front panel to be opened and permits lateral, vertical, and longitudinal adjustment of the cover position. A wire spring latch fastens the front panel in a closed position and provides for vertical latch position adjustment. A rear panel side latch is opened with a depressible latch opener at the rear of the cover. An intermediate panel latch fastens the intermediate panels down at the side of the pickup truck bed. These latches release automatically when the cover is folded. Another intermediate panel side latch has a wire spring pin that can be manually or automatically disengaged. The cover also has wind deflecting sloped side edges integral with the panel frame and hinges integral with the panel frame. Novel seals seal the junctions between adjacent panels.

    Abstract: A low silhouette cargo bay cover for pickup trucks and the like includes an angle member mounted on the cargo bay sides equipped with a flexible gasket to form a seal with the cover. The cover has a special narrow panel adjacent the cab to make it possible to more completely expose the cargo area of the turck and improved seal means at each of the hinges to more effectively exclude moisture.

  • Patent number: 4844531
    Abstract: The cover for the otherwise open cargo bed of a pickup truck includes a plurality of rectangular panels hinged together laterally of the cargo bed so as to fold forwardly in accordion fashion for storage as a compact stack at the forward end of the bed. The panels are thin whereby the stack has a low silhouette and does not obstruct the rear window of the cab. At least the sides of the cover are enclosed by an upstanding gasket which shields the cover from the vehicle's slip stream and crosswinds which would otherwise make it necessary to provide a tie-down for the cover when in cargo bay closure position.
