Abstract: A modular roll-out floor for use as a temporary, removable cover over an ice surface, the floor includes a plurality of interconnected and disconnectable treads. Each tread is made of three layers: a top portion is made of high impact plastic with an anti-slip surface on a honeycomb structural design for strength and rigidity, an intermediate portion designed as an insulating thermal barrier layer and a lower portion, which is also made of high impact plastic with a honeycomb structural design for strength and rigidity. The three portions are connected to each other. The treads may be connected to other treads to form a floor of any size. Living hinges on each tread allow the floor to be easily rolled up and stored.

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.
