US Patent 11618506 Trailer floor panel

A panel for constructing a trailer floor is provided. The panel includes a platform from which a plurality of sidewalls extend from a first edge and a second edge, with slots therebetween for receiving cross members. The sidewalls engage with the cross members to inhibit movement of the sidewalls away from the slots, which simultaneously inhibits the panel from flexing. The inhibition of flexure of the panel increases the load carrying capacity of the panel, allowing utilization of lighter materials to achieve the same load carrying capacity as heavier materials.
