Abstract
A semi-trailer has a rear frame with a post extending vertically at a side of the rear frame adjacent a rear end of a trailer side wall. A joint is disposed between the post and the side wall rear end. The joint has a first portion that receives a portion of the rear end of the side wall and a second portion offset inward from the first portion that receives a portion of the post. At least one fastener extends through the portion of the post and the second portion of the joint, without extending through the exterior surface of the side wall.
Claims12
A semi-trailer, comprising:
- a wheeled chassis having at least two wheeled axles at a rearward end of the wheeled chassis, retractable legs, and a kingpin at a forward end of the wheeled chassis, wherein the wheeled chassis is elongated in a longitudinal dimension from the forward end to the rearward end;
- a body comprising
- a cargo deck supported by the wheeled chassis,
- a front wall at the forward end of the wheeled chassis,
- a pair of opposing side walls extending between the front wall and the rearward end of the wheeled chassis,
- a rear frame attached to the rearward end of the wheeled chassis and to each side wall at a rearward end of the side wall so that a cargo volume is bounded by the cargo deck, the front wall, the pair of opposing side walls, and the rear frame, wherein the rear frame has a first post extending vertically at a side of the rear frame adjacent a rear end of a first side wall of the pair of opposing side walls, and
- a first joint disposed between the first post and the rear end of the first side wall, wherein the first joint comprises
- a first portion that defines a first receiving surface that receives a portion of the rear end of the first side wall that includes a surface of the first side wall that is exterior with respect to the cargo volume, and
- a second portion offset, in a dimension transverse to the longitudinal dimension and inward with respect to the cargo volume, from the first portion that defines a second receiving surface that receives a portion of the first post;
- and
- at least one fastener that extends through the portion of the first post and the second portion of the first joint, without extending through the exterior surface of the first side wall.
