Abstract
A golf ball has a plurality of dimples in its spherical outer surface and its spherical outer surface is divided into the faces of an icosahedron consisting of 20 regular large spherical triangles. Six (6) great circle paths further divide the golf ball's spherical outer surface into the faces of an icosidodecahedron consisting of 20 regular spherical triangles and 12 regular spherical pentagons. The dimple covalent boundary lines are made evenly and uniformly parallel to the regular dividing lines between the regular spherical triangles and the adjacent regular spherical pentagons. The dimple covalent areas are made between the regular spherical triangles and the adjacent regular spherical pentagons. Therefore, the total surface area of dimples are maximized which is a characteristic of the golf ball. On the polar region, two new larger spherical pentagons are made from the dimple covalent boundary lines which are positioned outside of the regular spherical pentagon along great circle paths on both sides of the polar region. On the equatorial region, ten new smaller spherical pentagons are made from the dimple covalent boundary lines which are positioned inside of the regular spherical pentagons along great circle paths on the equatorial region. A golf ball having a dimple arrangement in accordance with the present invention maximizes flying distance while maintaining the flying stability by obtaining a balance of the dimple free areas on the polar region and the dimple free areas at the equatorial region (mold parting line).
