Benefits of technology

[0004] It is an objective of this invention to provide a trailer having a sidewall assembly formed of a plurality of composite panels that reduce the thickness and weight of the side structures. The composite panels of the invention comprise a polyurethane core thermally bonded to inner and outer metal panels or skins. The edge portions of each of the composite panels are respectively riveted to a plurality of side posts having a hat-shaped sectional cross section and to outer posts. The inner surface created by the composite panels and the intervening surfaces of the side posts create a generally smooth and snag free surface. The sidewall assembly herein disclosed is strong, durable, and lightweight, and is easily repaired.

Problems solved by technology

Such sheet and post trailers do not optimize interior cargo space because of the width of the sidewall structure.
Many prior attempts to reduce the thickness of the sidewall of a trailer have suffered from several disadvantages, including extra weight, higher repair costs and designs that are not optimumly strong under all loading conditions.
Prior art post and sheet sidewall constructions are also not efficiently durable and are not economical to manufacture and repair.

Embodiment Construction

[0019] Referring now to FIG. 1-12, there is illustrated a first embodiment of the composite sidewall assembly of the invention to be described in detail herein. In FIG. 1, a general perspective view of a trailer embodying the teachings of the invention is shown. The present invention is not restricted to the particular trailer shown in FIG. 1, but more broadly relates to the construction of cargo containers, including, but not limited to, trailers, vans and the like. In FIG. 1, trailer 2 includes a standard landing gear 4, a floor 6 and a front wall 8. Conventional wheel assemblies 10 are provided at the rear of the trailer 2. The trailer is further provided with the sidewall assembly 12 of the invention to be described more fully herein. Referring to FIGS. 2 and 3, the interior cargo space 14 of the trailer 2 is defined by floor 16, sidewall assemblies 12 on opposite sides of trailer 2, roof 18 (FIG. 2), and front wall 8.

Abstract

A sidewall assembly for a trailer or van having a plurality of composite panels interconnected along the length of the trailer. The composite panels have a polyurethane core sandwiched between inner and outer metal panels in bonded relationship. The composite panels are affixed to a respective hat-shaped inner side post between adjacent vertical ends of the composite panels. A plurality of vertically arranged rivets affixes the composite panel to inner post and to an outer sidepost.

Description

BACKGROUND OF THE INVENTION [0001] This application claims priority to U.S. provisional application No. 60 / 635,145 filed Dec. 10, 2004.FIELD OF THE INVENTION [0002] This invention relates in general to trailers and, more particularly, to a trailer having a sidewall assembly including composite panels interconnected by side posts. SUMMARY OF THE PRIOR ART [0003] A common form of a cargo carrying trailer or van relies on a sheet and post design for its sidewall construction. Known sheet and post designs employ a plurality of hat-shaped side posts to which outer and inside metal side sheets are riveted by a vertical array of rivets. Such sheet and post trailers do not optimize interior cargo space because of the width of the sidewall structure. Many prior attempts to reduce the thickness of the sidewall of a trailer have suffered from several disadvantages, including extra weight, higher repair costs and designs that are not optimumly strong under all loading conditions. Prior art post...
