Abstract
A four sided tile, particularly for paving, flooring or cladding includes a first side edge, a second slide edge parallel with shorter than the first side edge, and third and fourth side edges which are not parallel. The length of the shorter side edges is the same and the sum of their length is equal to the length of the larger side. The side edges are preferable curved with radii of equal length.
Claims20
A tile comprising:
- a first side edge,
- a second side edge,
- third and fourth side edges which extend between the first and second side edges,
- the second, third and fourth side edges being of substantially equal length,
- the length of the first side edge being substantially the sum of the lengths of the other three side edges,
- all of the side edges being of curvilinear shape, and
- each side edge defining a portion of a circle, the radii of curvature of all of the side edges being substantially equal.
