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 the said peripheral surface, said dimples defining intersection circles where they intersect with said peripheral surface, said intersection circles being distributed on said peripheral surface in accordance with a repetitive motif determined by subdivision of said peripheral surface along 6 equatorial circles of which each is centered on an axis passing through respective midpoints of two diametrically opposed edges of a cube inscribed in said sphere, in a manner to define 24 elemental surfaces in the form of a spherical isosceles right-angle triangle, inside which said intersection circles are essentially distributed, at least a 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 mutually cutting in pairs or threes at determined points of intersection on each said hemisphere, wherein at least one intersection circle is arranged about a respective one of said points of intersection of three of said equatorial circular arcs.

Abstract
The present invention relates to a golf ball.
The peripheral surface (2) of the golf ball has dimples defining, by their intersection with this peripheral surface (2) intersection circles (55,57,59,61,62,63) which in their majority (55,57,59,61,62) are distributed essentially inside 24 identical elemental surfaces (50) in spherical isosceles right-angle triangle form defined by 6 equatorial circles (44 to 49) of the sphere defining the general shape of the peripheral surface (2) of the ball (3) each of the equatorial circles (44 to 49) being centered on an axis passing through the respective midpoints of two diametrically opposed edges of a cube inscribed in this sphere; a determined one (48) of these equatorial circles cutting none of the intersection circles subdividing each of the other equatorial circles (44,45,46,47,49) into two circular arcs (44a and 44b, 45a and 45b, 46a and 46b, 47a and 47b, 49a and 49b) which mutually cut in threes at points (7,11) of the peripheral surface (2), at least one (63) of the intersection circles being arranged around a respective one of the these points (7,11).
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 (48) is avoided.
