US Patent 7938428 Bracket assembly for a fifth wheel coupling

A bracket assembly for an adjustable fifth wheel hitch is suitable for mounting to a slide rail assembly, which itself is mounted to parallel longitudinal truck frame members, where the slide rails have a generally t-shaped cross-section. The slide rail is comprised of a horizontal portion and a vertical portion, the vertical portion including a plurality of spaced-apart gaps. The bracket assembly comprises a bracket body with longitudinal disposed front and rear ends, with respect to the truck body, a longitudinal channel defined in the underside that extends from front and rear openings defined in the respective surfaces of the front and rear ends with a generally t-shaped cross-section to slidably receive said slide rail. The bracket body also has two spaced-apart transverse channels defined in the underside, perpendicular to the longitudinal channel. The transverse channels align with two of the space-apart gaps as the bracket body is slid along the slide rail. The bracket body also includes a rounded upper portion for providing pivoting support to a fifth wheel hitch plate, and forward and rear tie-bar flanges extending from one side of the lower portion of the body for mounting support for a tie bar to mutually tie brackets together.
