ABSTRACT:
The present invention refers to an arrangement of dimples on a golf ball which has a plurality of dimples on its spherical surface, The arrangement of dimples is made by dividing sphere's surface of a golf ball by great circles to form an octahedron, making the center of a spherical triangle in the said octahedron as a pole, and dividing again the said sphere's surface by great circles to form a new octahedron at the position turning on the said pole as a center in an angle of 60 degrees, and dividing again the said sphere's surface by great circles made by extending the lines connecting the adjacent midpoints of the sides of spherical triangle with a pole to one another, and dividing again the said sphere's surface by great circles made by extending the lines connecting the adjacent midpoints of the sides of spherical triangle at the position turning on the said pole as a center in an angle of 60 degrees to one another, and arranging dimples in the spherical polygons formed in dividing the said sphere's surface by great circles made by extending the lines connecting the midpoints of apices on spherical triangle with a pole as a center and the apices of spherical triangle at the position turning in an angle of 60 degrees to the pole. The aforementioned spherical polygons are composed of 2 spherical hexagons, 12 spherical pentagons, 12 spherical rhombuses and 12 spherical triangles.
