DESCRIPTION:
BRIEF SUMMARY
This invention relates to paving and tiling.
Paving as a means of providing an acceptable surface for use by pedestrians and traffic has long been known, in the form of paving tiles or slabs traditionally used for pedestrian areas, pavements and the like, and in the form of so-called cobblestones, traditionally used for both pedestrian areas and road surfaces.
The increasing provision of traffic-free pedestrian areas has caused increased attention to the visual effect of a paved or cobblestoned area, and with conventional square or rectangular paving slabs or cobblestones, whilst some variation of pattern and hence surface effect is possible, the number of variations that are possible is very small.
This has led in some instances to first the designing of a desired pattern for a paved or cobblestoned area, and then the production of paving slabs or cobblestones of particular shapes to enable them to be laid to create the required pattern and hence visual effect. This is obviously inconvenient and expensive.
In other instances, it has led to consideration being given to the creation of shapes of, particularly, paving slabs, and where paving slabs of one or a small number of different shapes can be laid side-by-side with a large number of variations of pattern and hence visual effect, than is permitted by conventional square or rectangular shapes, and it is the object of the present invention to provide such shapes.
Equally well-known is the tiling of walls and floors to provide a hard wearing surface of pleasing aesthetic effect. Predominantly, such tiles are square or rectangular, relying on a surface pattern on the tiles to create the desired visual appearance.
According to the present invention, a block or tile comprises a body having each of its ends formed by two equally and oppositely curved surfaces that meet on the general center plane of the body, and generally parallel side surfaces to the body extending between the outer end of the curved surfaces, with one end of the block or tile formed by two equally and oppositely curved convex surfaces, the junctions between the side surfaces and the equally and oppositely curved concave end surfaces to the opposite end lie respectively on a projection of the arcs forming the convex surfaces.
Thus the block or tile of the invention has a generally chevron-like appearance and blocks and tiles can be placed in side-by-side and end-to-end relationship to generate a multiple number of patterns.
Most desirably the operative surface of the block or tile can be patterned or decorated in such a manner that the pattern or decoration on one block or tile blends with the pattern or decoration on an adjacent tile to enhance the appearance generated by the blocks or tiles. Thus, for example, the surface of a block can be patterned to simulate a number of small cobblestones, the simulated cobblestones to each side of a block may be of an arcuate pattern curved in the same direction as the convex and concave surfaces to that side of the block. Thus, an arcuate pattern of one block is continued by the arcuate pattern on an adjacent block to further enhance the appearance.
Particularly with blocks, it is further preferred to form the two sides with castellations that interfit with the castellations on the sides of adjacent blocks, to mask the joint between adjacent blocks, which castellations may be created by simulated cobblestones when provided as the pattern on the surface.
To provide a variety of patterns, a variety of generally rectangular shapes can be provided. Thus a block or tile based on a square can be employed to produce a regular pattern. Alternatively a rectangular shape where the ends are longer than the sides to create a laterally elongate or stretched pattern can be employed. Equally a rectangular shape where the sides are longer than the ends can be employed to create a longitudinally elongate or squashed pattern.
Several embodiments of the invention will now be described by way of example, with reference to the accompany wings, in which:
