DETAILED DESCRIPTION
DETAILED DESCRIPTION
[0018] In the description that follows, like parts are marked throughout the specification and drawings with the same reference numerals. The drawing figures may be to scale and certain components can be shown in generalized or schematic form and identified by commercial designations in the interest of clarity and conciseness.
[0019] Prior art paving systems includes those where the pavers are differently sized units, each of which is an integer multiple of a basic rotational tessellation element.
This configuration has the effect of interrupting the joint pattern and making the pavers less regular in appearance.
Although the various units fit together, it is difficult for an installer to assemble the pavers, and this idea has largely failed in the marketplace.

Although the various units fit together, it is difficult for an installer to assemble the pavers, and this idea has largely failed in the marketplace.
[0020]
Another prior art paving system is the single-piece system, wherein all of the units are of the same size and form a repeating pattern that is easier to install. The repeating pattern is disguised in part by false joints in the stones themselves, but the single piece system, which unavoidably has a joint surrounding each unit, also has limitations that render it unacceptable. First, the sides of the stones generally extend from the vertices of the tessellation. So, although the joints are irregularly shaped, they intersect at regular intervals along a straight line, and the joints meet in perfect crossing alignment with each other. These characteristics degrade the illusion of randomness in the completed pavement.

[0021]
Second, sides of adjacent stones have the same length, which introduces another degree of artificiality, and which further degrades the illusion of randomness. Third, the sides of adjacent stones are rotational images of one another, and have the same configuration with only minor variations in the sides. This characteristic limits the ability to imitate hand-split flagstone, which rarely fractures into polygons of any significant concavity. The result is sides which conform closely, and revealingly, to those of the base tessellation array, because for one stone to depart from the array in a credible, convex way requires the adjacent stone to have an incredible, concave side.

The result is sides which conform closely, and revealingly, to those of the base tessellation array, because for one stone to depart from the array in a credible, convex way requires the adjacent stone to have an incredible, concave side.
[0022] Fourth, the use of 120 degree rotational tessellations makes layout and installation difficult for workmen accustomed to rectilinear arrangements. Constructing a rectangular pavement requires either, 1) overlaying and trimming the perimeter, which is costly, or 2) employing a variety of specially-configured termination blocks, which creates estimating and inventory challenges.
[0023] The present disclosure addresses these problems. In one exemplary embodiment, pavers derived from a Cairo pentagonal tiling are used to form the arrangement of stones.
The arrangement is fundamentally orthogonal, integrates more readily with common landscape features (such as rectangular building foundations), and is simple to lay-out with common tools such as try squares, string lines, and Pythagorean triangles.
The arrangement is fundamentally orthogonal, integrates more readily with common landscape features (such as rectangular building foundations), and is simple to lay-out with common tools such as try squares, string lines, and Pythagorean triangles.
[0024] Second, although the perimeter of each stone fits within a common block-bounding polygon, the vertices of the polygon are substantially displaced from the vertices of its associated Cairo pentagon, resulting in joints that intersect imperfectly with each other, and also in the misalignment of the joint intersections with the axes of the tiling array.
[0025] Third, the misalignment of the joint intersections results in abutting sides of adjacent stones having different lengths, which also helps to obscure the Cairo-pentagonal shape that is the basis of each paver. Fourth, the sides of adjacent stones are not images of one another. Instead, substantial gaps, notches, and intersecting false joints on one side of a joint bear no complementary resemblance to the side of the stone on the opposite side of the joint.
[0026] Fifth, the disclosed block-bounding polygon is significantly concave, and the stones inscribed therein include false joints to visually subdivide them into multiple substantially convex polygons, which conform to the usual appearance of flagstone. Sixth, the Cairo pentagon is easily subdivided into two termination stones, which together in normal arrangement can replace a whole stone in the array, together in abutting arrangement can form a straight edge termination, and pairs thereof can easily form outside 90 degree corners.
[0027] One aspect of the present disclosure is the avoidance of rotational images, which improves the ability to avoid readily observable repeating patterns. Rotational images are avoided by using perimeter segments that do not mate or conform to each other, but which also do not interfere with each other. In addition, multiple sides are used to form the perimeter segments for adjacent pavers, which improves the ability to avoid rotational images, mating sides and other inferior features that result in readily discernable repeating patterns.
[0028] FIGURE 1 is an isometric projection of a first paving stone 100, in accordance with an exemplary embodiment of the present disclosure. Paving stone 100 and all other paving stones disclosed herein can be formed from concrete, masonry or other suitable materials, can be wet cast, dry cast or manufactured in other suitable manners.
[0029] As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising,"
when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As used herein, phrases such as "between X and Y" and "between about X and Y" should be interpreted to include X and Y. As used herein, phrases such as "between about X and Y" mean "between about X and about Y." As used herein, phrases such as "from about X to Y" mean "from about X to about Y."
when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

[0030] Paving stone 100 includes false joints 102 and 104, which separate the upper surface of paving stone 100 into a large area 106, an intermediate area 108 and a small area 110. In this manner, paving stone 100 appears to be three different stones to a casual observer, and the false joints 102 and 104 also help to channel water to the joints between paving stone 100 and adjacent paving stones. Paving stone 100 also includes upper perimeter segment surface 112 and lower perimeter segment surface 114, where upper perimeter segment surface 112 gradually decreases in diameter from the diameter of lower perimeter segment surface 114. In this manner, the minimum spacing between paving stone 100 and adjacent paving stones can appear to be approximately the same as the spacing of the false joints.
[0031] FIGURE 2 is a top view of a first paving stone 200, in accordance with an exemplary embodiment of the present disclosure. Cairo pentagon overlay 202 shows the outline of an ideal or virtual Cairo pentagon, and the outline of paving stone 200 can be seen to deviate from Cairo pentagon overlay 202. In particular, a portion 210 of large section 204 extends significantly beyond the boundary of Cairo pentagon overlay 202, and the point of contact between large section 204 and small section 208 forms a corner of space 212 within Cairo pentagon overlay 202, where space 212 is approximately equal in size to portion 210 of large section 204. Likewise, intermediate section 206 extends for a smaller section 214 outside of Cairo pentagon overlay 202, and intermediate section 206 forms a corner of space 216 with large section 204, where space 216 is approximately the size of smaller section 214.
[0032] The perimeter of paving stone 200 is formed in one of two configurations - either offset perimeter segment 218 or flat perimeter segment 220. Offset perimeter segment 218 is located along a continuous section opposite from flat perimeter segment 220, and is oriented so that paving stone 200 can be readily fitted with other paving stones of the disclosed paving system, by assembling the paving stones so that an offset perimeter segment 218 is adjacent to a flat perimeter segment 220, or in other suitable manners.
[0033] Each of the five perimeter segments 274, 276, 278, 280 and 282 are formed from, multiple sides or portions of sides, so as to avoid rotational images. For example, perimeter segment 274 is formed from a portion of side 270, side 272 and a portion of side 250, and thus avoids the creation of a vertex where perimeter segment 274 meets with perimeter segment 276 or perimeter segment 282. Likewise, perimeter segment 276 is formed from a portion of side 250, side 252, side 254 and a portion of side 256, which avoids the creation of a vertex at the intersection of perimeter segment 276 and perimeter segment 278. Perimeter segment 278 is formed from a portion of side 256, side 258, side 260 and most of side 262, although it will be recognized by one of skill in the art that the "sides" that are discussed herein with respect to every exemplary embodiment are not really sides, as they are formed from irregular shapes that are not straight line segments and are not amenable to characterization as a true "side." Perimeter segment 280 is formed from a portion of side 262 and most of side 264, and perimeter segment 282 is formed from a portion of side 264, sides 266 and 268, and most of side 270. As can be seen, no vertices are formed in paving stone 200 that correspond to the intersection of perimeter segment 280 with perimeter segment 278 or perimeter segment 282.
[0034] Paving stone 200 also includes notches 222, 224 and 226, which are used to improve the random appearance of paving stone 200 when it is used in conjunction with other pavers, and which also provides a space for water to drain from the surface of paving stone 200.
[0035] Paving stone 200 thus has a bottom surface with a fixed orientation relative to its associated Cairo pentagon.
The perimeter of the bottom surface encloses an area greater than about 90% of the area of the Cairo pentagon, but can include greater or lesser areas as suitable. At least about 8% of the bottom surface falls outside the boundaries of the Cairo pentagon, although more or less can fall outside as suitable. In addition, paving stone 200 has no vertices that coincide with the vertices of its associated Cairo pentagon, which helps to avoid the creation of a rotational image. In application, the minimum distance between a perimeter segment of paving stone 200 and a vertex of its associated Cairo pentagon can be within about 10 mm or other suitable distances, can be within about 5% of the total length of the perimeter or other suitable distances, and can have other suitable unique or repeating features. Likewise, while a Cairo pentagon is used in the disclosed embodiments, other suitable shapes can be used as the basis for a paving stone in accordance with the present disclosure, where the paving stone has the other disclosed features and functional attributes as disclosed herein.

Likewise, while a Cairo pentagon is used in the disclosed embodiments, other suitable shapes can be used as the basis for a paving stone in accordance with the present disclosure, where the paving stone has the other disclosed features and functional attributes as disclosed herein.
[0036] While it is recognized that paving stone 200 and other paving stones as disclosed herein also have certain non-functional and ornamental attributes, the ability to have a paving stone system with a small number of different stones that nonetheless creates a random appearance provides the functional attributes of reducing an amount of manual work that is required to create a paving stone layout with a random appearance, reducing the number of different types of paving stones that need to be kept on site to create a random appearing paving stone section, facilitating the easy placement of paving stones within a common rectangular space while maintaining a random appearance, and numerous other benefits as further discussed and disclosed herein, such as facilitating the drainage of water from the surface of the paving stones.
[0037] FIGURE 3 is an isometric projection of a second paving stone 300, in accordance with an exemplary embodiment of the present disclosure. Paving stone 300 includes false joints 302 and 304, which separate the upper surface of paving stone 300 into a large area 306, an intermediate area 308 and a small area 310. In this manner, paving stone 300 appears to be three different stones to a casual observer, and the false joints 302 and 304 also help to channel water to the joints between paving stone 300 and adjacent paving stones. Paving stone 300 also includes upper perimeter segment surface 312 and lower perimeter segment surface 314, where upper perimeter segment surface 312 gradually decreases in diameter from the diameter of lower perimeter segment surface 314. In this manner, the minimum spacing between paving stone 300 and adjacent paving stones can appear to be approximately the same as the spacing of the false joints.
[0038] FIGURE 4 is a top view of a second paving stone 400, in accordance with an exemplary embodiment of the present disclosure. Cairo pentagon overlay 402 shows the outline of an ideal Cairo pentagon, and the outline of paving stone 400 can be seen to deviate from Cairo pentagon overlay 402. In particular, a portion 410 of large section 404 extends significantly beyond the boundary of Cairo pentagon overlay 402, and the point of contact between large section 404 and intermediate section 406 forms a corner of space 412 within Cairo pentagon overlay 402, where space 412 that is approximately equal in size to portion 410 of large section 404. Likewise, small section 408 extends for a smaller section 414 outside of Cairo pentagon overlay 402, and small section 408 forms a corner of space 416 with large section 404, where space 416 is approximately the size of smaller section 414.
[0039] The perimeter of paving stone 400 is formed in one of two configurations - either offset perimeter segment 418 or flat perimeter segment 420. Offset perimeter segment 418 is located along a continuous section opposite from flat perimeter segment 420, and is oriented so that paving stone 400 can be readily fitted with other paving stones of the disclosed paving system, by assembling the paving stones so that offset perimeter segment 418 is adjacent to flat perimeter segments 420, or in other suitable manners.
[0040] Perimeter segment 428 is formed from a portion of side 468, side 438 and a portion of side 440. Perimeter segment 430 is formed from a portion of side 440, sides 442, 444, 446 and 448 and a portion of side 450. Perimeter segment 432 is formed from a portion of side 450, sides 452, 454 and 456 and most of side 458. Perimeter segment 434 is formed from a portion of side 458 and most of side 460. Perimeter segment 436 is formed from a portion of side 460, sides 462, 464 and 466, and most of side 468. The vertices of perimeter segments 428, 430, 432, 434 and 436 do not coincide with any vertex of sides of paving stone 400, and thus avoid any rotational images. In addition, the large number of sides of paving stone 400 and the variations in the number of sides of perimeter segments 428, 430, 432, 434 and 436 results in non-matching perimeter segments that are not rotational images of other perimeter segments, and which do not match perimeter segments on other paving stones, which helps to avoid the creation of easily-observable repeating patterns while simplifying installation.
[0041] Paving stone 400 also includes notches 422, 424 and 426, which are used to improve the random appearance of paving stone 400 when it is used in conjunction with other pavers, and which also provides a space for water to drain from the surface of paving stone 400.
[0042] Paving stone 400 thus has a bottom surface with a fixed orientation relative to its associated Cairo pentagon.
The perimeter of the bottom surface encloses an area greater than about 90% of the area of the Cairo pentagon, but can include greater or lesser areas as suitable. At least about 8% of the bottom surface falls outside the boundaries of the Cairo pentagon, although more or less can fall outside as suitable. In addition, paving stone 400 has no vertices that coincide with a vertex of its associated Cairo pentagon, which also helps to avoid the creation of a rotational image. In application, the minimum distance between a perimeter segment of paving stone 400 and a vertex of its associated Cairo pentagon can be within about 10 mm or other suitable distances, can be within about 5% of the total length of the perimeter or other suitable distances, and can have other suitable unique or repeating features. Likewise, while a Cairo pentagon is used in the disclosed embodiments, other suitable shapes can be used as the basis for a paving stone in accordance with the present disclosure, where the paving stone has the other disclosed features and functional attributes as disclosed herein.

[0043] FIGURE 5 is an isometric projection of a third paving stone 500, in accordance with an exemplary embodiment of the present disclosure. Paving stone 500 includes false joints 502 and 504, which separate the upper surface of paving stone 500 into a large area 506, an intermediate area 508 and a small area 510. In this manner, paving stone 500 appears to be three different stones to a casual observer, and the false joints 502 and 504 also help to channel water to the joints between paving stone 500 and adjacent paving stones. Paving stone 500 also includes upper perimeter segment surface 512 and lower perimeter segment surface 514, where upper perimeter segment surface 512 gradually decreases in diameter from the diameter of lower perimeter segments surface 514. In this manner, the minimum spacing between paving stone 500 and adjacent paving stones can appear to be approximately the same as the spacing of the false joints.
[0044] FIGURE 6 is a top view of a third paving stone 600, in accordance with an exemplary embodiment of the present disclosure. Cairo pentagon overlay 602 shows the outline of an ideal Cairo pentagon, and the outline of paving stone 600 can be seen to deviate from Cairo pentagon overlay 602. In particular, a portion 610 of intermediate section 606 extends significantly beyond the boundary of Cairo pentagon overlay 602, and the point of contact between large section 604 and intermediate section 606 forms a corner of space 612 within Cairo pentagon overlay 602, where space 612 is approximately equal in size to portion 610 of intermediate section 606.
Likewise, small section 608 extends for a smaller section 614 outside of Cairo pentagon overlay 602, and small section 608 forms a corner of space 616 with large section 604, where space 616 is approximately the size of smaller section 614.
Likewise, small section 608 extends for a smaller section 614 outside of Cairo pentagon overlay 602, and small section 608 forms a corner of space 616 with large section 604, where space 616 is approximately the size of smaller section 614.
[0045] The perimeter of paving stone 600 is formed in one of two configurations - either offset perimeter segment 618 or flat perimeter segment 620. Offset perimeter segment 618 is located along a continuous section opposite from flat perimeter segment 620, and is oriented so that paving stone 600 can be readily fitted with other paving stones of the disclosed paving system, by assembling the paving stones so that offset perimeter segment 618 is adjacent to flat perimeter segment 620, or in other suitable manners.

The vertices of perimeter segments 628, 630, 632, 634 and 636 do not coincide with any vertex of sides of paving stone 600, and thus avoid any rotational images. In addition, the large number of sides of paving stone 600 and the variations in the number of sides of perimeter segments 628, 630, 632, 634 and 636 results in non-matching perimeter segments that are not rotational images of other perimeter segments, and which do not match perimeter segments on other paving stones, which helps to avoid the creation of easily-observable repeating patterns while simplifying installation.
