Abstract
Abstract A generally horizontal platform is provided for removable support from the side of a truck body having a bay doorway therein and defining opposing upstanding door receiving channels extending along opposite sides of the doorway and a lower horizontal sill structure extending between the lower ends of the opposite side marginal portions of the doorway. The platform includes a horizontal panel structure including opposite side marginal edge portions and opposite inner and outer marginal edge portions extending between the opposite side marginal edge portions. The platform further includes oppositely endwise outwardly directed stub axle portions supported therefrom and projecting outwardly from the ends of the side marginal edge portions adjacent the inner marginal edge portion. The stub shaft portions are slidingly and rotatingly receivable in the aforementioned channels and the platform also includes a pair of braces dependingly supported from the side marginal edge portions of the panel and including upstanding abutment surfaces facing outwardly the inner side marginal portion of the panel for abutting engagement with the outer surface of the sill. The braces are hingedly supported from the panel for inward and upward swinging movement toward retracted positions general paralleling and immediately underlying the panel.
