ABSTRACT:
The invention relates to a golfball having a plurality of dimples in its outer spherical surface The dimples have various sizes and depths and are configured in a pattern that is based upon dividing the golfball's surface into a spherical octahedron having eight octahedral triangles and a spherical hexaoctahedron having eight hexaoctahedral triangles and six hexaoctahedral quadrangles. The two poles of the golfball are located within centers of oppositely facing octahedral triangles ("pole triangles"). The remaining six octahedral triangles ("equator triangles") are intersected by the golfball's equator through the two of their three midpoints that are not in contact with the pole triangles.
Six dimples of equal size (having equivalent diameters) are placed in a circle around the centers of each of the eight octahedral triangles. A plurality of dimples having equal size are uniformly placed along the three great circles that define the octahedron, except that no dimple is to be placed along or overlap the golfball's forming joint region, which is incident to the equator. In addition, a dimple of the largest size is placed adjacent to each apex of each of the eight octahedral triangles. A dimple of the largest size is also placed next to each midpoint of each side within each of the two pole triangles. Also, a dimple of the second largest size is placed next to each midpoint of each side within each of the six equator triangles.
