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 substant…
