ABSTRACT:
According to the present invention, a slatted floor system comprises a plurality of elongated, spaced, generally parallel slats. Each slat has a top, load-carrying surface with spaced apart, opposite outer edges; a bottom surface substantially parallel to the top surface; and a pair of side surfaces integral with the top surface and the bottom surface. The side surfaces are joined with the top surface along lines recessed from the outer edges of the top surface. The side surfaces further taper toward each other in first portions, adjacent the top surface, then extend substantially parallel to each other and vertically relative to the bottom surface in second portions, thereby forming with the top and bottom surfaces a generally Y-shaped, enclosed main compartment. Each slat also includes a first pair of projection receiving means extending longitudinally along the tapered first portion of its side surfaces and a second pair of projection receiving means extending longitudinally along the second portion of the side surfaces. Adjacent slats are connected and locked in spaced-apart relationship by a plurality of connectors. Each connector has a first pair of projections, with each projection being receivable by one of the first pair of projection receiving means on each of two adjacent slats, and a second pair of projections, with each projection being receivable by one of the second pair of projection receiving means on each of two adjacent slats. At least one of the first and second pairs of projections on the connector is adapted to interlock with its corresponding projection receiving means on adjacent slats.
