BACKGROUND OF THE INVENTION
Field of the Invention 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 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 and sheet sidewall constructions are also not efficiently durable and are not economical to manufacture and repair. Accordingly, it is desirable to provide a trailer having a sidewall assembly that is economical to manufacture and to operate, is durable during use, and provides a reduced sidewall thickness to increase cargo space and reduce weight.
SUMMARY OF THE INVENTION
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.
