## Abstract

A flooring substrate system of polymer, open cell structural panels that may be attached to framing members beneath or placed atop of a waterproof membrane roof or deck structure. The panels are attached by a clip with a mechanical fastener that can be screwed into the lower framing members at a range of angles relative to the plane of the panel while the mechanical fastener and clip remain in complete mating engagement. The panels may also be operationally positioned using a disk that either has a threaded post that is bolted to the panel through a pin block and washer, a fixed pin or a pair of spring arms that lock onto rabbets in the panel's top face.

## Claims

### Claim 1

A system for the attachment of a planar substrate above a structural surface, said planar substrate adapted for the attachment of a flooring product, comprising;
a structural panel having a top face, a bottom face and a repeatable series of adjacent open voids formed therethrough, said voids with four tapered, internal void sides sloping inward toward a center of said void, wherein said top face of said panel has linear rabbets formed along each of a cell's top edge at an interface between the top of said void sides and said top face of said panel;
at least one four sided, four cornered, planar rigid clip for the retention of said structural panel onto a structural surface or member located there below said clip having a small tab extending from each of said four clip sides dimensionally sized for engagement with said rabbets, and wherein said four corners are bent with respect to said plane of said clip, and said clip having a hemispherical indentation formed thereon with an orifice formed therethrough a midpoint of said indentation;
a mechanical fastener having a threaded shaft with a hemispherical body drive head at a proximal end of said shaft, wherein said mechanical fastener is capable of pivotal movement within said hemispherical indentation of said clip, while said hemispherical indentation remains completely matingly engaged by an outer surface of said hemispherical body drive head;
wherein when said clip is inserted into said cell said small tabs engage in said rabbets, and said corners frictionally engage said internal void sides.

### Claim 2 (depends on 1)

The system for the attachment of a planar substrate above a structural surface of claim 1 wherein said shaft has a first outer diameter and said orifice has an inner diameter, wherein said inner diameter exceeds said first outer diameter.

### Claim 3 (depends on 2)

The system for the attachment of a planar substrate above a structural surface of claim 2 wherein said hemispherical drive head has a second outer diameter and said second outer diameter exceeds said inner diameter.
