Abstract: A lift-roof cover 10 for a light truck open load bed 12, comprising a lift-roof structure 15 pivotally attached about a lateral axis A--A to the upper edge 44 of the cover forward wall 18, the forward wall 18 being fixedly mounted to the load bed 12 so that, alternately, secure weatherproof enclosure of the load bed 12 may be provided with the lift-roof structure 15 in a lowered position, or the lift-roof structure 15 may be raised at the rear about the lateral axis A--A, providing improved access to the load bed 12. A preferred embodiment incorporates the use of compression struts 74, 76 to provide lift assist in raising the lift-roof structure 15 and accommodates the application of flexible curtains 146 to provide full enclosure with the lift-roof structure 15 in a raised position, while maintaining commonality with methods of manufacture, handling, shipping and storage employed for high volume production load bed covers of the prior art.

Abstract: A lift-roof cover for a light truck open load bed, comprising a lift-roof structure pivotally attached about a lateral axis to the lower edge of the cover forward wall, the forward wall being fixedly mounted to the load bed with flexible weatherproof panelling interposed between the lift-roof structure and the forward wall so that, alternately, secure weatherproof enclosure of the load bed may be provided with the lift-roof structure in a lowered position, or the lift-roof structure may be raised at the rear about the lateral axis, providing improved access to the load bed. A preferred embodiment incorporates the use of compression struts to provide lift assist in raising the lift-roof structure and accomodates the application of flexible curtains to provide full enclosure with the lift-roof in a raised position, while maintaining high degrees of commonality with methods of manufacture, handling, shipping and storage employed for high volume production load bed covers of the prior art.

Abstract: A flat-floored trailer having wheels, a load bed and coupling structure assembly including a load floor structure having a lateral cross section in the form of an "inverted top hat" and comprising a central rectangular floor panel attached by suitable fastener means along each longitudinal edge to the lower horizontal flange of a formed panel incorporating a lateral section of "Z" form with a vertical wall joining the lower horizontal flange to an upper horizontal flange or floor surface; the right formed "Z" section panel being a mirror image form of the left formed "Z" section panel and each formed panel being shaped in a parallel configuration of bends and edges and being of approximately the same length as the central rectangular floor panel;the load bed being attached to an "A" frame coupling structure comprising left and right structural bar legs joined at their forward ends to a common coupling bracket and joined toward, but forward of, their rearward ends to a common structural bar cross member; the "
