Grass paving structure

Claim 2

A grass paving structure comprising: a plurality of hexagonal cells nested to form a single unit having a first, second, third and fourth side; the first and second sides of the nested cell unit forming complementary sawtoothed walls; the third and fourth sides of the nested cell unit forming complementary half-hexagonal walls, and an integrally formed base supporting the nested cell unit having a first and second edge underlying said first and second sides, respectively, said first and second edges formed as complementary arcuate undulations that extend beyond the recessions of the first and second sides, and third and fourth edges underlying said third and fourth sides, respectively, said third and fourth edges formed as complementary half-hexagonal periodic shapes that extend beyond the recessions of the third and fourth walls; whereby when one grass paving structure is positioned adjacent to another, they interlock and support each other in one plane and support each other in another plane.

Claim 3

The grass paving structure of claim 1 further including a plurality of cleats formed on the bottom side of said base.

Claim 4

The grass paving structure of claim 1 wherein said base includes a circular opening beneath each hexagonal cell.

Claim 5

The grass paving structure of claim 3 wherein the walls of each hexagonal cell have a notch in the upper edge thereof.

Claim 6

The grass paving structure of claim 1 wherein each said arcuate undulations comprises alternating curves of the same arc and radius.

Claim 7

A hexagonal cell structure for installation with an identically formed structure, the hexagonal cell structure having sawtooth sides along first respective opposite sides and a series of spaced apart, half hexagons on second respective opposite sides; and a base means underlying said hexagonal cell structure; said base means, along first respective opposite sides being contoured as complementary half-hexagonal periodic shapes such that a portion of each half-hexagon extends beyond said base means, thereby providing a half hexagonal extension, and such that said base means provides a surface means between each adjacent half-hexagon for receiving an overlying half hexagonal extension of said identically formed structure; said base means, along second respective opposite sides, being contoured as complementary arcuate undulations such that a portion of each sawtooth extends beyond said base means, thereby providing a sawtooth extension, and such that said base means provides a surface means between each adjacent sawtooth for receiving an overlying sawtooth extension of said identically formed structure; whereby when one hexagonal cell structure is positioned adjacent to another, they interlock and support each other in one plane and support each other in another plane.

Claim 8

A hexagonal cell structure for installation with an identically formed structure, the hexagonal cell structure having sawtooth sides along first respective opposite sides and a series of spaced apart, half hexagons on second respective opposite sides; and a base means underlying said hexagonal cell structure; said base means, along first respective opposite sides being contoured as complementary half-hexagonal periodic shapes such that a portion of each half-hexagon extends beyond said base means, thereby providing a half hexagonal extension, and such that said base means provides a surface means between each adjacent half-hexagon for receiving an overlying half hexagonal extension of said identically formed structure; said base means, along second respective opposite sides, being contoured as complementary arcuate undulations such that a portion of each sawtooth extends beyond said base means, thereby providing a sawtooth extension, and such that said base means provides a surface means between each adjacent sawtooth for receiving an overlying sawtooth extension of said identically formed structure; whereby when one hexagonal cell structure is positioned adjacent to another, they interlock and support each other in one plane and support each other in another plane.

Claim 9

A hexagonal cell structure for installation with an identically formed structure, the hexagonal cell structure having sawtooth sides along first respective opposite sides and a series of spaced apart, half hexagons on second respective opposite sides; and a base member underlying said hexagonal cell structure; said base member, along first respective opposite sides being contoured such that a portion of each half-hexagon extends beyond said base member, thereby providing a half hexagonal extension, and such that said base member provides complementary half-hexagonal periodic shapes for receiving overlying half hexagonal extensions of said identically formed structure; said base member, along second respective opposite sides, being contoured such that a portion of each sawtooth extends beyond said base member, thereby providing a sawtooth extension, and such that said base member provides complementary arcuate undulations for receiving overlying sawtooth extensions of said identically formed structure; whereby when one hexagonal cell structure is positioned adjacent to another, they interlock and support each other in one plane and support each other in another plane.

Claim 10

A hexagonal cell structure for installation with an identically formed structure, the hexagonal cell structure having sawtooth sides along first respective opposite sides and a series of spaced apart, half hexagons on second respective opposite sides; and a base member underlying said hexagonal cell structure; said base member, along first respective opposite sides being contoured such that a portion of each half-hexagon extends beyond said base member, thereby providing a half hexagonal extension, and such that said base member provides complementary half-hexagonal periodic shapes for receiving overlying half hexagonal extensions of said identically formed structure; said base member, along second respective opposite sides, being contoured such that a portion of each sawtooth extends beyond said base member, thereby providing a sawtooth extension, and such that said base member provides complementary arcuate undulations for receiving overlying sawtooth extensions of said identically formed structure; whereby when one hexagonal cell structure is positioned adjacent to another, they interlock and support each other in one plane and support each other in another plane.
