ABSTRACT:
A modular platform suitable for use as a portable roll-out walkway or floor comprising a plurality of interconnected treads of a lightweight molded or formed thermoplastic material, each of the treads comprising a top surface for supporting loads thereon, a ground-engaging bottom surface, and four side portions comprising two adjacent male side portions and two adjacent female side portions disposed between the bottom and top surfaces, the side portions comprising interconnecting member integral with the tread for selectively disengageable interconnection with adjacent treads to configure the platform in variable sizes as desired. The top surface comprises drainage apparatus to allow passage therethrough of air and water. The bottom surface comprises a plurality of ribs spaced so as to form cavities in cooperative relation with the drainage apparatus so as to disperse weight loads, allow passage thereto of water drained through the drainage apparatus, and maintain a moisture canopy underneath the treads. Each of the male side portions comprises an insertion member disposed substantially along the length thereof, comprising an integral living hinge to allow hinged pivoting and an interlocking tab. Each of the female side portions comprises a channel member disposed substantially along the length thereof and adapted to mate with an opposing insertion member located on an adjacent tread, the channel member comprising a mating slot disposed thereon so as to mate in snap-fit relation with an interlocking tab of an adjacent tread when the insertion member of the interlocking tread is inserted in the channel member.
