Abstract
A multi-purpose golf ball having 812 concave hexagonal surface depressions arranged in a uniformly arranged geodesic nine-frequency icosahedral pattern over the surface of the ball and each depression having a surface diameter in the range of from 0.090 inches to 0.140 inches and a depth in the range of from 0.002 inches to 0.014 inches.
Claims1
A multi-purpose golf ball having 812 concave hexagonal surface depressions uniformly arranged over the surface thereof,
- each of said hexagonal depressions having a surface diameter in the range of from 0.090 inches to 0.140 inches and having a depth in the range of from 0.002 inches to 0.014 inches,
- said 812 hexagonal depressions being uniformly arranged over the surface of the ball in a nine frequency geodesic or curved icosahedral pattern defined by twenty main triangles with each side of each main triangle divided into nine parts to form a total of 812 intersecting vertices uniformly distributed over the entire surface of the ball, and
- each of said depressions being centered on the point of intersection of each of the vertices.
