Golf ball
First Claim
1. A golf ball having an equator (16) which is a great circle path about said golf ball, said great circle path being defined as a circle on the surface of the ball formed by a plane which passes through the center of the ball, and first and second poles (14) on the surface of the golf ball, the poles being the points where a line perpendicular to the said plane of the ball and which passes through the center of the ball intersects the surface of the golf ball, and said golf ball having a plurality of dimples on the surface thereof, said dimples being distributed on the surface of the golf ball according to the configuration of a tetrakaidecahedron projected onto the surface of the golf ball, said projected tetrakaidecahedron comprising two spherical hexagons (10) and twelve spherical trapezoids (12), one said spherical hexagon (10) having as its center point the first pole (14) and the other said spherical hexagon having as its center point the second pole (14), the legs (24) of each hexagon (10) serving as a top (24) of each spherical trapezoid (12) and a section of the equator (16) serving as a base of each spherical trapezoid (12), each of the sides (18) of each of the spherical trapezoids (12) extending from a vertex of the spherical hexagon (10) to the equator (16), all said spherical trapezoid sides (18) being equal in length and each said spherical trapezoid (12) having the shape of a truncated spherical isosceles triangle, and said dimples being symmetrically positioned on the surface of the golf ball to correspond to the layout of the hexagons and trapezoids of the said tetrakaidecahedron projected onto the surface of the ball.

Abstract
An arrangement for dimples on the surface of a golf ball is disclosed. The golf ball surface is subdivided by projecting a tetrakaidecahedron onto the surface thereof. Dimples are arranged according to the location of the hexagons and trapezoids which comprise the tetrakaidecahedron. The hexagons and trapezoids can also be divided into triangles by inclusion of diagonals therein. With the inclusion of diagonals, up to ten great circle paths can be defined and the dimples can be arranged so that they do not intersect any of the great circle paths.
