A COVERING UNIT

摘要

A covering unit for use in combination with similar units for covering a surface with a natural random look, the unit having an hexagonal body compri sing first, second and third pairs of opposed and parallel sides. Each side has a central point of angular symmetry. The second and third pairs are simi lar to each other while the first pair is different from the others. The sid es of the second and third pairs are provided with at least one split deviat ion along their length arranged so that each side of the second pair is a ro tational image of the sides of the third pair, whereby in use in combination with other covering units: each side is matingly engageable with the sides of an equivalent pair of a neighbouring unit; and the unit has a central poi nt of angular symmetry and is matingly engageable with a plurality of neighb ouring unit.
