Abstract:
1. A paving stone comprised of a polygonal body formed with: substantially parallel upper and lower faces; a plurality of substantially planar sides extending perpendicularly between the faces; a row of substantially identical and outwardly projecting narrow coupling members all of a uniform predetermined member width on each of the sides and separated from one another by spaces of a predetermined uniform space width, the narrow coupling members being positioned on the respective sides such that when a plurality of the paving stones are fitted together with their upper faces generally coplanar the narrow coupling members of confronting sides of adjacent paving stones fit between one another; and a single wide coupling member on each of the sides and of a width greater than that of the uniform member width of the narrow members and smaller than the space width, the wide member being separated from adjacent narrow members on the respective side by the predetermined uniform space width, the wide member further being oriented such that when a plurality of the paving stones are fitted together with their upper faces generally coplanar the wide members fits between two of the narrow members of a confronting side of an adjacent paving stone and the narrow members on the confronting sides are out of contact with one another.
