US 7,988,382 B2 · Artificial flagstone for providing a surface with a natural random look

Abstract

An artificial flagstone for use in combination with other similar flagstones for covering a surface with a natural random look, the flagstone having a generally hexagonal body comprising a first, second, third, fourth, fifth and sixth consecutive vertices; a first pair of generally congruent irregularly-shaped first and second sides extending radially from the first vertex and being rotationally spaced from each other by an angle α of approximately 120°; a second pair of generally congruent irregularly shaped third and fourth sides extending radially from the third vertex and being rotationally spaced from each other by an angle β of approximately 120°; a third pair of generally congruent irregularly shaped fifth and sixth sides extending radially from the fifth vertex and being rotationally spaced from each other by an angle ω of approximately 120°; wherein the sides of each of the first, second and third pair of sides have at least one split deviation along their length and are respectively rotational images of each other, whereby in use in combination with other flagstones, each one of the sides is matingly engageable with the sides of an equivalent pair of sides of a neighboring flagstone.

An artificial flagstone for use in combination with other ones of said artificial flagstones for covering a surface with a natural random look, the flagstone having a generally hexagonal body comprising:

a first, second, third, fourth, fifth and sixth consecutive vertices;
a first pair of generally congruent first and second sides extending radially from the first vertex and being rotationally spaced from each other by an angle α of approximately 120°;
a second pair of generally congruent third and fourth sides extending radially from the third vertex and being rotationally spaced from each other by an angle β of approximately 120°;
and
a third pair of generally congruent fifth and sixth sides extending radially from the fifth vertex and being rotationally spaced from each other by an angle ω of approximately 120°;
wherein the sides of at least one of said first, second and third pair of sides have at least one split deviation along their length and are respectively rotational images of each other, whereby in use in combination with said other flagstones, each one of said sides is matingly engageable with the sides of an equivalent pair of sides of a neighbouring flagstone, wherein the artificial flagstone has no rotational symmetry when rotated about a central axis.

a first, second, third, fourth, fifth and sixth consecutive vertices;
a first pair of generally congruent first and second sides extending radially from the first vertex and being rotationally spaced from each other by an angle α of approximately 120°;
a second pair of generally congruent third and fourth sides extending radially from the third vertex and being rotationally spaced from each other by an angle β of approximately 120°;
and
a third pair of generally congruent fifth and sixth sides extending radially from the fifth vertex and being rotationally spaced from each other by an angle ω of approximately 120°;
wherein the body of the flagstone is divided into a bottom part devised to contact the surface to cover and an upper part topping the bottom part, the upper part having a contour line generally similar to the bottom part and a surface area smaller than the surface area of the bottom part whereby spaces are created between the upper part of adjacent flagstones covering a surface, wherein the artificial flagstone has no rotational symmetry when rotated about a central axis.
