Abstract

An arena floor useful alternately as a support for a slab of artificially frozen ice, and, when free from ice, as a deck suitable e.g. for practicing gymnastics and various games, is composed of a plurality of elongate elements held together in side by side relationship on top of a flat supporting bed. The elongate elements, which somewhat resemble matched boards and add only a few centimeters at most to the height of the bed, are formed by extrusion in desired lengths from plastic and have selected cross sectional shapes including passages permitting the circulation longitudinally through the elements of a temperature controlling fluid. By suitably selecting the plastic used in extruding said board-like elements the resiliency and hardness thereof, and hence of the floor as a whole, may be varied to fit different kinds of activities.
