Abstract
Abstract A slide for each end of a pick up truck tailgate; the slide allowing the tailgate shaft to be lifted from a U-shaped cup-portion of the slide, and allowing the shaft to be slided under the truck bed; the bracing arms that normally support the tailgate in a rearwardly horizontal position will in this design support the upper end of the tailgate as the tailgate is horizontally slided underneath the truck bed; the tailgate having a lip at its lower end for holding the shaft in the U-shaped cup when the tailgate is in rearward horizontal loading position.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
214 words
An adjustable tail gate assembly in combination with a vehicular body having a rear end with said tail gate assembly pivotally mounted on the rear end of said body, including a vehicular bed surface extending to the tail gate with spaced sides enclosing said surface, said tail gate being pivotally mounted to said sides by means whereby said tail gate is pivotable from an upper vertical position to horizontal positions, including a rear storing position, providing a loading surface extending rearwardly beyond said bed surface and a forward loading position beneath said bed surface, said body having a space beneath said bed surface to receive said tailgate, said means comprising a pair of shafts extending laterally from said tail gate toward said sides, further including a pair of slides mounted on said sides receiving said shafts slidably, said slides extending from the rear end of said body forwardly a sufficient distance to receive and support said shafts when the tailgate is in the storing position, further including forward retaining means extending from said tailgate for contact with said body beneath said bed surface when said tailgate is in said loading position, also including rearward retaining means pivotally securing a rear portion of said tailgate to said sides to resist downward pivoting of said tailgate.
