ABSTRACT:
An articulated cover assembly for covering the top opening of trailers and the like having two covers which are movable between a position covering at least a portion of the top opening of a trailer and a position substantially removed from the trailer. The covers travel upon a track such that they may be rolled between the opened and closed positions. The covers are preferably comprised of a rigid material, such as plastic or fiberglass. A tongue and groove interface intermediate the two covers provides a seal therebetween. The track may be comprised of two track sections: a horizontal first track section comprised of two elongate rails positioned upon opposite sides of the trailer and extending horizontally therealong, and a second track section comprised of two elongate rails positioned at either end of the trailer and sloping downward from approximately the height of the first track section. Rollers contacting the first track section are mounted upon a trunnion plate to facilitate variances in the angular orientation of the cover relative to the rollers as the cover moves between the open and closed positions. An electric motor and chain drive may be utilized to move the covers between the open and closed positions.
