Wall joint configuration

Abstract

The wall joint of the present invention is configured to reduce or eliminate protrusions into the interior of the trailer or container, but does not require coining or stamping of the edges of consecutive sidewall panels. According to some highly preferred embodiments of the present invention, the wall joint includes two consecutive sidewall panels, each bent to form a main plateau, a spliced plateau and a jogged portion serving as a transition therebetween. In this way, the spliced plateau lies in a plane substantially parallel to, but spaced apart from, the main plateau, with the thickness of the sidewall panel most preferably remaining substantially constant throughout. When two consecutive sidewall panels are positioned next to each other, the spliced plateaus of the two consecutive sidewall panels abut each other and lie in a first plane, while the main plateaus of the two panels preferably lie in another parallel plane. Thus, a region recessed from the main plateaus and surrounding the seam between the two panels is created. The main plateaus preferably comprise the bulk of the interior, generally smooth-walled, surface of the cargo body, interrupted only by periodic recessed regions created by the spliced plateaus at the seams between the sidewall panels. While it is preferable for the main plateaus to lie in a single plane to create a generally flat interior cargo body wall, it is not necessary. In some highly preferred embodiments, adhesive and rivets are employed to further strengthen the sidewall panel joints.
