Abstract
Abstract A surface decking or mat-like sheet material is provided having a lower surface with generally flat portions adapted to lie on a floor, ground or other generally flat surface, and an upper surface having a plurality of parallel spaced unidirectional recessed passageways separated by upwardly extending portions having spaced parallel unidirectional sides which also form the sides of said passageways, said recessed passageways having bottom portions extending between said parallel sides, the exterior sides of said bottom portions constituting said generally flat portions of said flat surface, said bottom portions containing a plurality of spaced openings extending through said lower surface, and said upper surface between said passageways containing a plurality of spaced openings having upwardly extending rims which act as bearing surfaces for animals, persons, or objects in contact therewith.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
166 words
Surface decking comprising a molded, unitary, resilient sheet material formed throughout with a plurality of parallel rectangular corrugations of substantial length, width and thickness, the bottom parts of said corrugations forming a lower surface adapted to lie on a floor, ground or other generally flat surface and the upper parts of said corrugations forming an upper surface, a plurality of rows of spaced openings in the bottom part of each corrugation, and a plurality of rows of spaced openings in the upper part of each corrugation, said rows on the upper part are parallel to the length of the corrugation, said last named spaced openings having upwardly extending rims, the tops of said rims are of substantial width sufficient to act as bearing surfaces for animals, persons or objects in contact with the upper surface of said decking, and downwardly extending, reinforcing ribs disposed on the opposing side of the bearing surface, said ribs are centrally located between each pair of adjacent rows of rimmed openings.
Claim 2
Dependent Claim

A decking as claimed in claim 1 which is in the form of a rectangular panel having greater length than width wherein said openings in said lower surface are aligned transversely and longitudinally of said panel in spaced pairs and said rimmed openings are polygonal in shape and are aligned longitudinally and staggered transversely in spaced pairs, the opposite sides of said panel terminating in said lower surface at approximately one-half of the normal corrugation width so that the edge line is straight and extends longitudinally with only a single series of longitudinally aligned holes therein whereby another identical panel can be secured in butted relationship at said edge line to produce a matching combination of said panels.
Claim 10
Dependent Claim
29 words
A decking as claimed in claim 1 mounted on a supporting surface with sand or other inert granular material covering said supporting surface and lower surface in said decking.
