Golf ball
First Claim
1. A golf ball comprising a peripheral surface having a general form 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 centred on a centre of said sphere and mutually connecting points of said peripheral surface corresponding to determined points of a polyhedron inscribed in said sphere, said circular arcs defining elemental spherical surfaces and said dimples being essentially inside said elemental surfaces wherein said polyhedron is a hexa-octohedron and said sub-division is carried out along 12 equatorial circles of which each is centred on an axis passing through respective mid-points of 2 diametrically opposed edges of said hexa-octahedron, and passes through 2 diametrically opposed apices of this in a manner to define:
- 6 identical ones of said elemental surfaces having spherical, regular octagonal form,48 identical ones of said elemental surfaces having spherical triangle form having an obtuse angle,24 first identical ones of said elemental surfaces in the form of spherical quadrilaterals having 2 opposite angles equal to said obtuse angle and 2 different opposite angles, defined by 2 respective equal length sides,24 second identical ones of said elemental surfaces in the form of spherical quadrilaterals different from said spherical quadrilaterals and having 2 opposite angles equal to the difference between 180° and
said obtuse angle and 2 different opposite angles defined by 2 respective sides of equal length,24 third identical ones of said elemental surfaces in the form of spherical quadrilaterals different from said spherical quadrilaterals and having 2 opposite angles equal to said difference and 2 different opposite angles, defined by 2 respective sides of equal length.

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 (123,124,125,126) essentially distributed inside 126 elemental surfaces (104,105,106,115), delimited by 12 equatorial circles (92 to 103) of the sphere defining the general shape of the peripheral surface (2) of the ball (3), on the basis of:
6 identical elemental surfaces (104) of spherical, regular octagonal form,
48 identical elemental surfaces (105) of spherical triangular form,
3 groups of 24 identical elemental surfaces (106,231,115) of spherical quadrilateral form having two equal opposite angles (107,108,131,116,117) and two different opposite angles (109,110,133,134,118,119) defined by two respective equal length sides (111,112,113,114,135, 136,137,138,120,121,122,123).
