  • Patent number: 6173548
    Abstract: A floor for a basketball court or the like assembled from a plurality of separate floor sections arranged in staggered rows with each section including a plurality of spaced apart sleepers, a subfloor secured to the sleepers, and a wood strip flooring layer secured to the subfloor. Abutting edges of adjoining floor sections are reinforced by tongues and complementary edge pockets mounted on respective abutting edges of adjoining sections. The edge pockets may be formed by recessing the subfloor inwardly of outer edges of the sleepers and the flooring layer. A similar edge pocket may be formed on the adjoining floor section that the tongue is received into. Each tongue is preferably fabricated of a tough, non-marring polymeric material such as ultra-high molecular weight plastic. Alternatively, a similar tongue and pocket arrangement may be formed by mounting a tongue and bracket set on the subfloors of adjoining floor sections.

  • Patent number: 5987839
    Abstract: A portable activity floor comprised of a plurality of separate panels that can be readily and selectively interlocked together into a finalized configuration. Each panel has an underlayment providing a core with spaced stringers fastened to the underside thereof. Elongated finishing strips mounted on the upper surface of the underlayment form the outer surface of the panel. In one type of floor assembly, alternate strips are longer than their adjacent strips at the inner side of each panel to form laterally spaced interlock fingers. A pair of hinge members pivotally connects adjacent panels to one another and allows them to be relatively pivoted on a fixed axis with finger interlock alignment accuracy from an initial connected position to a fully assembled position in which the fingers of the finishing strips closely mesh and interlock. Further, the hinge members when connected prevent lateral movement of adjacent panels.

  • Patent number: 5121579
    Abstract: A floor section assembly having a post anchor built into one of the floor panels for use with portable sectionalized flooring suitable for a volleyball court or the like is disclosed. The post anchor includes a base assembly attached to the undersurface of one of the panels and is coupled to a plurality of adjacent panels by tubes attached to the undersurface of the panels and coupled together by a rigid member extending through aligned tubes. This structure provides a broad base of support for the post carrying a volleyball net which can absorb moments placed on the post without the need for connecting the post to the base on which the flooring is assembled.
