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 defining by their intersection with this circles of intersection distributed on said peripheral surface in accordance with a repetitive motif determined by subdivision of said peripheral surface along:
- 3 equatorial circles of which each is centred on an axis passing through respective centres of two diametrically opposed faces of a cube inscribed in said sphere,4 equatorial circles of which each is centred on an axis passing through two diametrically opposed apices of said cube,in a manner to define 24 identical first elemental surfaces in the form of a spherical isosceles right-angle triangle and 8 second identical elemental surfaces in the form of a spherical equilateral triangle, said intersection circles being distributed essentially inside said first and second elemental surfaces, at least one determined one of said equatorial circles, cutting none of said intersection circles and subdividing each of the others of said equatorial circles into two equatorial circular arcs, of which each corresponds to one of two hemispheres defined by said determined equatorial circle, said equatorial circular arcs cutting each other in pairs or threes at determined points of intersection on each said hemisphere;
whereinat least one intersection circle is arranged about a respective one of said points of intersection of 3 of said equatorial circular arcs.

Abstract
The present invention relates to a golf ball.
The peripheral surface (2) of the ball has dimples defining by their intersections with this peripheral surface (2) intersection circles (55,57,59,60,64,68,70) which, in their majority (55,57,59,60,64,68), are distributed essentially inside 24 identical elemental surfaces (40) in spherical isosceles right-angle triangle form, and 8 second identical elemental surfaces (45) in spherical equilateral triangle form, which elemental surfaces (40,45) are defined by 4 equatorial circles (36,37,39) of the sphere defining the general shape of the peripheral surface (2) of the ball (3), eahc of the equilateral triangle (36,37,39) being centered on an axis passing through two diametrically opposed apices of a cube inscribed in this sphere, and by 3 equatorial circles (29,30,31) of this sphere, which are centered on axes passing through the respective centers of two diametrically opposed surfaces of the cube; the determined one (29) of these equatorial circles nevertheless cuts none of the intersection circles and subdivides the other equatorial circles (30,31,36,37,39) into two circular arcs which mutually cut at points (49,50) of the peripheral surface (2 ); at least one of these intersection circles is disposed about a respective one of these points (49,50).
The orientation of the ball with respect to the strike can thus be rendered substantially independent, while a strike on the said determined equatorial circle is avoided.
