Golf ball
First Claim
1. A golf ball comprising a peripheral surface having a general shape of a sphere and a plurality of dimples arranged in said peripheral surface and distributed on the latter in accordance with at least one repetitive motif defined by sub-division of said peripheral surface along arcs of equatorial circles centred on a centre of said sphere and mutually connecting points of said peripheral surface corresponding to determined points of a cube inscribed in said sphere, said circular arcs defining elemental spherical surfaces and said dimples being essentially inside said elemental surfaces, wherein said sub-division is carried out along:
- 6 said equatorial circles of which each is centred on an axis passing through respective mid-points of two diametrically opposed edges of said cube and passes through four apices of the latter,3 said equatorial circles of which each is centred on an axis passing through respective centres of two diametrically opposed faces of said cube and passes via radial projections, onto said surface, of respective mid-points of 4 mutually parallel edges of said cube,in a manner to define 48 identical elemental surfaces in spherical right-angle triangle form.

Abstract
The present invention relates to a golf ball. In order to improve the indifferent character of the orientation of the ball with respect to the strike, the peripheral surface (2) of it has dimples (69) essentially distributed inside 48 identical elemental surfaces (68), in the form of spherical right-angle triangles, delimited by 9 equatorial circles (56 to 61, 65 to 67) of the sphere defining the general shape of the peripheral surface (2) of the ball (3).
