ABSTRACT:
A walk board system comprises at least first and second platform assemblies, each assembly having first and second pairs of support legs pivotally connected to the platform. At least one of said pairs of legs presents a staircase for user entry onto the platform. The legs are selectably extensible to vary the height of the platform above the underlying ground surface. The legs are pivotable to a position within the confines of the platform so as to allow for easy transport of the platform assembly between work sites. About the perimeter of each platform are a plurality of slots designed to engage a depending flange of a fastener member therein. Upon placement of the platforms in a side-by-side relationship and alignment of selected slots therebetween, insertion of a fastener within the aligned slots will maintain the platforms in selectable adjacent relationships. The plurality of slots about the perimeter of each platform allows for the platforms to be placed in various adjacent relationships inclusive of straight line, corner or offset relationships. A tool holder on each platform allows for deposit of tools or other articles therein.
