Abstract:
A surface covering unit includes at least one face comprised of at least one primary rotational tessellation element. The rotational tessellation element includes at least two pairs of sides, and the sides in each pair of sides have the same length and are images of one another. The sides of a first pair of sides extend from a first vertex and are rotationally spaced from each other, and the sides of a second pair of sides extend from a second vertex and are rotationally spaced from each other. The sides of the first and second pairs of sides have two or more straight line segments or complex curves, and are not a single straight line or a single curve. One pair of sides has a length different from the other pair of sides. The surface covering has a natural appearance such that a repeating pattern is not readily apparent.
Abstract:
A surface covering comprises multiple units adapted to mate with one another and cover a surface. Each said unit comprises at least one primary rotational tessellation element that defines the sides of the unit, has an irregular configuration, includes a face having molded surface irregularities or variations therein, and has at least two pairs of irregularly shaped sides. Preferably, gaps of variable width are defined between visible edges of adjacent units in the surface covering. The surface covering has a natural appearance such that a repeating pattern is not readily apparent. A structural wall unit system is also provided.
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 first and second sides extending radially from the first vertex; a second pair of third and fourth sides extending radially from the third vertex; a third pair of fifth and sixth sides extending radially from the fifth vertex; wherein the sides of at least one 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, and the artificial flagstone has no rotational symmetry when rotated about a central axis.
Abstract:
An irregular, tessellated building unit comprises x primary elements, wherein x is an integer equal to or greater than 1. The primary element is a rotational tessellation having a plural pairs of sides extending in a generally radial direction from plural vertices, respectively. In each pair, the two sides are rotationally spaced by an angle that is divided evenly into 360 degrees. Preferably, all of the sides are irregularly shaped, but one or more sides could be wholly or partially straight. Optionally, spacers are provided on the sides of each unit. A wide variety of units may be constructed having different numbers and arrangements of primary elements. As all the units are combinations of primary elements, they readily mate with each other. A surface covering comprises a multiplicity of units assembled to form a continuous surface without overlap between units and without substantial gaps between units. A structure, such as a wall or column can be formed of building units of the invention. Because of the irregular side configurations, and different sizes and shapes of individual units, the resulting surface or structure has a natural, non-repeating pattern appearance. Optionally, minor surface and edges variations are made from unit to unit to further enhance the natural appearance of the surface covering or structure.

Abstract:
The invention relates to a set of concrete pavers, comprising substantially rectangular pavers of uniform height with vertical side faces, a number of pavers of uniform or different lengths and widths being arranged in a row, and, in particular for forming a rectangular or square laying bundle that can be picked up by machine, comprising a number of parallel, adjacent rows of pavers, continuous linear joints being formed in the end-paver region of the rows of pavers when the sets are laid together or, optionally, substantially meandering joints being obtainable by interchanging row-end pavers, which are of different lengths and are in close proximity, from neighboring sets; at least one section of the upper delimiting surface of the pavers is convexly cambered towards the outside and projections on the base parts of the pavers are spaced apart on the side faces of the base parts, the projections forming support elements for the adjacent pavers and, in combination with projections on adjacent pavers, creating spaces that act as water-drainage openings in the joint regions, the pavers in each set comprising not only paving blocks with a length-to-height ratio of less than or equal to 4 but also at least one paving slab with a length-to-height ratio greater than 4.

Abstract:
Multiple molded polymeric panels of various configurations are mechanically fastened together along a side surface having alternating upright and downward facing steps containing fastening elements to provide putting greens of different dimensions and shape. Each panel has a planar top surface and a bottom integral grid supporting structure. A simulated grass overlies the joined panels. Raised pads are optionally placed between the top surface of the panels and the simulated grass to provide a contoured green.
Abstract:
A family of convex and non-convex tiles which can be tiled together to fill a planar surface in a periodic or non-periodic manner. The tiles are derived from planar space frames composed of a plurality of regular p-sided polygonal nodes coupled by a plurality of struts. p is any odd number greater than three and an even number greater than four. The nodes and struts, along with the areas bounded by them, make up a tiling system. In addition, the lines joining the along the center lines of the struts define a large family of convex and non-convex tiles. The convex tiles include zonogons, and the non-convex tiles include tiles with one or more concave vertices. The latter comprise singly-concave, bi-concave and S-shaped tiles. The tiles can be converted to 3-dimensional space-filling blocks. When these blocks are hollow and inter-connected, architectural environments are possible. Other applications include tiles for walls, floors, and various architectural and other surfaces, environments, toys, puzzles, furniture and furnishings. Special art pieces, murals and sculptures are possible.
Abstract:
Families of node shapes based on prismatic symmetry for space frame constructions. The node shapes include various polyhedral, spherical, elipsoidal, cylindrical or saddle shaped nodes derived from polygonal prisms and its dual. The node shapes are determined by strut directions which are specified by various directions radiating from the center of a regular prism of any height. A plurality of such nodes is used in single-, double- or multi-layered space frames or space structures where the nodes are coupled by a plurality of struts in periodic or non-periodic arrays. The space frames are suitably triangulated for stability. Applications include a variety of architectural structures and enclosures for terrestrial or (outer) space environments. Suitable model-building kits, toys and puzzles are also possible based on the invention.
