The present invention relates to a golf ball. The peripheral surface of the ball has dimples defining, by their intersections with this peripheral surface (2), intersection circles (44,49,54,59,63) distributed essentially inside 6 first identical elemental surfaces (24) in four-sided regular spherical polyganol form, and 8 second identical elemental surfaces (22) in spherical equilateral triangle form, which elemental surfaces (22,29) are defined by 4 equitorial circles (18,19,20,21) of the sphere defining the general shape of the peripheral surface (2) of the ball (3), each of the equatorial circles (18,19,20,21) being centered on an axis passing through two diametrically opposed apices of a cube inscribed in this sphere; if there is defined as a diagonal circle of a first elemental surface (22) a circular arc (35,36) centered on the center (13) of the sphere (1) and joining two opposed apices (30,31,32,33) of the said regular spherical polygon, certain (44,49,54) of the said intersection circles (44,49,54,59,63) are arranged on the said diagonal circular arcs (35,36). As a function of the diameter attributed to the intersection circles (44,49,54,59,63) one can either render substantially unimportant the orientation of the ball with respect to the strike, or permit sufficient visualization of the elemental surfaces (22,29) for the player to be able to choose a strike zone. |
