Golf ball
First Claim
1. A golf ball comprising a peripheral surface having the 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 circles centered on a center 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 equatorial circles of which each is centered 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 equatorial circles of which each is centered on an axis passing through respective centers of two diametrically opposed faces of said cube and passes via radial projections, onto said sphere, of respective mid-points of 4 mutually parallel edges of said cube,4 equatorial circles of which each is centered on an axis passing through two diametrically opposed apices of said cube and passes through radial projections, onto said sphere, of the respective mid-points of six edges, in perpendicular pairs, of said cube,in a manner to define 48 first ones of said identical elemental surfaces and 48 second ones of said elemental surfaces identical between themselves but different from said first elemental surfaces, said first and second elemental surfaces being of spherical right-angle triangle form.

Abstract
The present invention relates to 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 (115,116) essentially distributed inside 2 groups of 48 elemental surfaces (113,114), identical in the same group and different from one group to the other in the form of spherical right-angle triangles, delimited by 13 equatorial circles (56 to 61, 65 to 67, 108 to 111) of the sphere defining the general shape of the peripheral surface (2) of the ball (3).
