Modular roll-out portable floor and walkway

A modular platform suitable for use as a portable walkway or floor comprising a plurality of interconnected elongate treads of a lightweight molded or formed thermoplastic material and substantially rectangular in plan, each of said treads comprising:

• (a) a top surface for supporting loads thereon, said top surface comprising drainage means comprising:
• (i) a drainage channel recessed with respect to said top surface and comprising a plurality of drainage openings to allow passage therethrough of air and water;
• and
• (ii) a plurality of raised portions spaced apart so as to form recessed spaces therebetween, said recessed spaces coupled with said drainage channel so as to aid in draining water off said top surface;
• (b) a ground-engaging bottom surface comprising a plurality of ribs extending in spaced relation therebetween, said ribs being spaced so as to form cavities between an underside of said top surface and the ground when said treads are placed on the ground, said cavities being in cooperative relation with said drainage means so as to allow passage thereto of water drained through said drainage means;
• and
• (c) four side portions comprising two adjacent male side portions and two adjacent female side portions disposed between said bottom and top surfaces;
• wherein each of said male side portions comprises:
• an insertion member, said insertion member being in inverted substantially U-shaped cross-section and disposed substantially along the length thereof, said insertion member comprising an integral living hinge formed by a cross-section relatively thinner in its middle than on adjacent outer portions thereof to allow hinged pivoting therebetween, and interlocking tab means comprising a resilient tab protrusion disposed on an outer portion thereof;
• and
• wherein each of said female side portions comprises:
• a channel member, said channel member being in substantially U-shaped cross-section and disposed substantially along the length thereof and adapted to mate with an opposing insertion member located on an adjacent tread;
• said channel member comprising mating slot means disposed thereon so as to mate in snap-fit relation with an interlocking tab means of an adjacent tread when the insertion member of said interlocking tread is inserted in said channel member;
• and tab disengagement means comprising a fulcrum opening perpendicularly juxtaposed with said mating slot for allowing insertion therein of a lever for selective disengagement of said interlocking tab means from said mating slot;
• whereby any number of said treads may be interconnected along any side portion to form a modular platform in any desired dimension, and whereby portions of said platform may be rolled as a result of the flexibility of the living hinges.
