Covering element for protecting banks and shores from waves is hexagonal with alternate straight and concave sides latter forming gentle cavities

摘要

The element (2) is regular hexagon shaped formed by cirumferential sides (7a-f). The sides (7a,7c,7e) are entirely flat and the sides (7b,7d,7f) concave forming gentle cavities (11). Near the vertices the concave surface into flat portions. The straight edges are formed by half elements (3,4). The adjacent elements are rotated over one side with respect to each other so that each element on all sides has a continuous cavity (11). Independent claims are also included for (a) the covering
