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.
