<p>PURPOSE: To make dimples on element-planes, which are the different element- planes from that of spherical right angled triangles, made along equatorial circles passing through each midpoint of antagonistic apexes of an inscribing cube to a golf ball. CONSTITUTION: Sub components are made along six equatorial circles 56 to 61 and four equatorial circles 108 to 111. The six equatorial circles passes through the both apexes of ridge lines having centers of axes 50 to 55, which pass through each midpoint of two antipole antagonistic ridge lines 13 to 24 of a cube 4. The four equatorial circles passes through to a sphere 1 via radial projections of midpoints 25 to 36 of six pairs of orthogonal ridgelines 13 to 24 that have axes lines 104 to 107 as centers, which pass through two antipole antagonistic apexes 5 to 12 of the cube 4. Then, forty eight pieces of spherical right angled triangle shaped element-planes 113 and twenty four pieces of element-planes each having two right antagonistic right angles 117 and 118 and two different angles 119 and 120 are formed between two sets of the same length sides, one having sides 121 and 122 and the other having sides 123 and 124.</p> |
