Abstract

A laminated dry floor system incorporates a grid having a lattice forming a first array of apertures. A support interlayer is adhered beneath the grid and has a second array of apertures in alignment with the first array, the first array of apertures, second array of apertures and thickness of the support interlayer configured to induce passage of a liquid. A wicking layer is in contact with the support interlayer opposite the grid. A base layer underlies the wicking layer and a pan assembly is configured to receive the base layer.

First claim

What is claimed is:

1 . A laminated dry floor system comprising:
a grid having a lattice forming a first array of apertures; a support interlayer adhered beneath the grid and having a second array of apertures in alignment with the first array of apertures, the first array of apertures, second array of apertures and thickness of the support interlayer configured to induce passage of a liquid; a wicking layer in contact with the support interlayer opposite the grid; a base layer underlying the wicking layer; and a pan assembly configured to receive the base layer.

2 . The laminated dry floor system as defined in claim 1 wherein the first array of apertures and the second array of apertures are concentrically aligned.

3 . The laminated dry floor system as defined in claim 1 wherein the grid comprises a lattice of intersecting members forming the first array of apertures, each of the intersecting members having a tapered cross section with an upper apex and a base surface.

4 . The laminated dry floor system as defined in claim 3 wherein the tapered cross section is triangular with sloping side surfaces extending from the upper apex to the base surface.

5 . The laminated dry floor system as defined in claim 1 wherein the grid is a thermoplastic.

6 . The laminated dry floor system as defined in claim 5 wherein the thermoplastic is urethane.

7 . The laminated dry floor system as defined in claim 1 wherein the support interlayer is titanium.

8 . The laminated dry floor system as defined in claim 1 wherein the support interlayer is aluminum or stainless steel.

9 . The laminated dry floor system as defined in claim 1 wherein the support interlayer has a thickness, T, and each aperture in the first array of apertures in the grid has a width, W, and T≤0.194 W.

10 . The laminated dry floor system as defined in claim 1 wherein the pan assembly comprises:
a dished pan having a rim configured to engage a bottom edge of the base layer, the dished pan having a cavity configured to collect liquid that passes through the grid, and
a plurality of surround members configured to fair the dished pan into a floor in which the pan assembly is installed.

11 . A grid assembly for a dry floor system, the grid assembly comprising:
a grid having a lattice forming a first array of apertures; a support interlayer adhered beneath the grid and having a second array of apertures in alignment with the first array of apertures, the first array of apertures, second array of apertures and thickness of the support interlayer configured to induce passage of liquid; a wicking layer in contact with the support interlayer opposite the grid; and a base layer underlying the wicking layer.

12 . The grid assembly as defined in claim 11 wherein the grid comprises a lattice of intersecting members forming the first array of apertures, each of the intersecting members having a triangular cross section with sloping side surfaces extending from an upper apex to a lower surface and wherein the first array of apertures and the second array of apertures are concentrically aligned.

13 . The grid assembly as defined in claim 11 wherein the grid is a thermoplastic.

14 . The grid assembly as defined in claim 11 wherein the support interlayer is titanium.

15 . The grid assembly as defined in claim 11 wherein the support interlayer has a thickness, T, and each aperture in the first array of apertures in the grid has a width, W, and T≤0.194 W.

16 . A method for maintaining a dry floor, the method comprising:
supporting a grid with a support interlayer adhered beneath the grid; receiving liquid in the grid, the grid having a lattice forming a first array of apertures, said support interlayer having a second array of apertures concentrically aligned with the first array of apertures; and receiving the liquid through the second array of apertures, the support interlayer having a thickness configured to induce contact of the liquid with a wicking layer adhered to a lower surface of the support interlayer.

17 . The method of claim 16 further comprising transmitting the liquid from a bottom surface of the wicking layer through a third array of apertures in a base layer beneath the wicking layer.

18 . The method of claim 17 further comprising receiving the liquid in a pan assembly.

19 . The method of claim 18 further comprising absorbing the liquid in an absorbent pad positioned in a cavity of a dished pan in the pan assembly.

20 . The method of claim 18 further comprising draining the liquid from a dished pan in the pan assembly to a reservoir.
