The cargo body of claim 1, wherein the interior side of each of the first and second longitudinal rails is provided with a longitudinally extending channel open along an interior side thereof, such that the longitudinally extending channels of the first and second longitudinal rails are open toward each other in facing relationship, and wherein the first end of the transverse beam is secured to the first longitudinal rail by the at least one fastener partially retained inside the channel of the first longitudinal rail and extending through the first end of the transverse beam, and wherein the second end of the transverse beam is secured to the second longitudinal rail by at least one additional fastener partially retained inside the channel of the second longitudinal rail and extending through the second end of the transverse beam.",
    "11. A cargo body comprising: a floor comprising a floor panel provided to support a load; a first longitudinal rail extending in a lengthwise direction of the cargo body, the first longitudinal rail having a longitudinally extending channel formed therein; a second longitudinal rail extending in the lengthwise direction of the cargo body, parallel to the first longitudinal rail at a fixed distance therefrom, the second longitudinal rail having a longitudinally extending channel formed therein; and a plurality of transverse beams spanning between the first and second longitudinal rails at various positions along the lengthwise direction, such that a first end of each of the plurality of transverse beams lies adjacent the first longitudinal rail and a second end of each of the plurality of transverse beams lies adjacent the second longitudinal rail, wherein each of the plurality of transverse beams is secured to the first and second longitudinal rails exclusively by a plurality of fasteners including at least one T-bolt having a head retained inside the channel of the first longitudinal rail and extending through the first end of the transverse beam, and at least one T-bolt having a head retained inside the channel of the second longitudinal rail and extending through the second end of the transverse beam.",
    "12. The cargo body of claim 11, wherein the end of each of the plurality of transverse beams includes an end cap having a slot with one open end and one closed end.",
    "13. The cargo body of claim 11, wherein the plurality of fasteners secure the plurality of transverse beams to the first and second longitudinal rails without penetration through exterior-facing sides of either of the first and second longitudinal rails such that exposed surfaces of the exterior-facing sides remain completely intact at locations of the plurality of transverse beams when secured.",
    "14. The cargo body of claim 11, further comprising first and second sidewalls extending both in the lengthwise direction and vertically from the floor panel.",

  "description_excerpt": "The invention relates to cargo body construction, for example, for over-the-road trailers pulled by semi tractors. In particular, the invention relates to trailer sidewall panels and joints for such sidewall panels, in addition to trailer doors, walls, floors, and roofs.\n\nIn some embodiments, the invention provides a method of assembling a roof of a cargo body. A plurality of sidewalls are provided, each comprising a side panel and an upper rail coupled to the side panel. A roof panel is located above the plurality of sidewalls adjacent the upper rails. A roof bow extends between the upper rails below the roof panel. The roof bow is fixed to a track of one of the upper rails with a fastener.\n\nIn some embodiments, the invention provides a cargo body comprising a floor comprising a floor panel and a cross member for supporting the floor panel, and a plurality of sidewalls, each sidewall comprising a side panel and a lower rail coupled to the side panel. The plurality of sidewalls extend from the floor at the lower rails and at least partially bound a cargo receiving volume in cooperation with the floor panel. The cargo body further comprises a track extending along each of the lower rails and a fastener coupling the cross member to the rail. The fastener is slidably adjustable to different positions along the track to position the cross member to different locations along the rail.",
