Abstract
Abstract A goods stacking platform comprises a base frame having a post upstanding from each corner, and a laterally projecting foot rigid with the lower end of each post having a fixed axis pivot connection to the base frame located to one side of the post providing for movement of the post between an erect upstanding position to a collapsed folded position substantially flatly overlying said base frame. Axially slidable offset locking pins distinct from the pivots are mounted on said base frame for displacement into corresponding apertures in the lower ends of said posts when the posts are erect.
