MARK- OG GOLVBELEGG, SAERLIG FOR TENNISPLASSER.

摘要

A surface covering for games arenas such as tennis courts comprising a slab shown inverted formed of a plurality of regular polygon shaped regions (1), e.g. squares, delimited by ribs (5) which depend from the upper load bearing surface of the slab and which abut the surface to be covered and by grooves (2) in the upper surface. Further ribs (3, 4) which depend from the upper surfaces are arranged to abut the surface to be covered, and radiate from the centre of each region. The grooves (2), ribs (3, 4) and apertures 6 allow small expansions or contractions of regions (1) due to temperature differentials to be absorbed by the individual regions (1) and allow larger changes to take place substantially in the plane of the covering, thus avoiding ridges and cavities which occur with known coverings. The outer edges are supported by semi-circular 11 or quarter-circular 13 pegs.
