RELATED APPLICATIONS
This application claims the benefit of prior co-pending U.S. patent application Ser. No. 10/923,889, Paving System Using Arrays of Vertically Interlocking Paving Blocks, by Weiss et al., filed Aug. 24, 2004, incorporated herein by reference.
BACKGROUND
Heretofore, providing a lateral attachment between laterally adjacent elements in a paving system has been a problem. U.S. Pat. No. 5,054,253, Rigid Grating Mat with Unidirectional Elements, to Bedics, Oct. 8, 1991, describes a system for
building a mat that has separate plank-like elements that are joined laterally by a tongue and groove construction. This makes for a complicated extrusion that is difficult to construct and is easily extended laterally only in one direction.
U.S. Pat. No. 5,429,451, Grid Matrix System Including Interconnected Revetment Blocks, to Pettee, Jul. 4, 1995, describes a grid matrix system that has interconnected revetment blocks. These square or . . . . More |

A method for fabricating and forming a continuous covered area, such as a
sidewalk or patio, employing vertically interlocking tessellated
components. One embodiment, termed PORTAPAVE.TM., achieves this
interlocking via an array of uniquely configured two-sectioned pavers.
Each paver has a first section of a first shape and a second section of a
second shape impressed upon the first section and bonded together. In one
embodiment, first sections of pavers are installed in a bottom layer to
form a cavity between them having the same shape as the second section of
a paver that is inverted onto the pavers of the bottom layer, thus
providing a top layer. Each inverted paver in this top layer is fitted to
interlock in that cavity formed between the un-inverted pavers in the
bottom layer.

I claim:
1. A method for covering a pre-specified area with vertically interlocking pavers, comprising: leveling said pre-specified area; providing components for a pre-specified array of said
pavers, said components comprising: a first section having first sides parallel to a first plane containing a first bearing surface and a first thickness in a second plane orthogonal to said first plane, said first thickness of a dimension less than that
of any of said first sides; and a second section having second sides parallel to both said first plane and a second plane containing a second bearing surface, said second plane parallel to said first plane, said second section contacting said first
section uniformly along a part of said first plane, said second section oriented to said first section such that said second sides are contained entirely within the perimeter formed by said first sides; arranging four said components in said
pre-specified array in a first plane parallel to . . . . More |
