Abstract
Abstract A floor for roller skating or other sports activities and the like consists of extruded metal deck sections of a required length which are placed side-by-side on an even solid surface. Juxtaposed plastic tiles or plates are laid down on the deck sections and are provided on their bottoms with press studs which interlock with continuous channels or grooves formed in the deck sections. Each plastic tile or plate engages at least a pair of the underlying deck sections and thus the tiles serve to secure adjacent deck sections in assembled relationship in the formation of a continuous floor.
