Golf ball
First Claim
1. In a golf ball including an outer cover having a spherical outer surface, said spherical outer surface having a plurality of dimples formed therein and arranged in a repeating pattern, said repeating pattern being defined by projecting onto said spherical outer surface the edges of an icosidodecahedron having 20 regular triangular faces and 12 regular pentagonal faces, and the edges of said icosidodecahedron, as projected onto said spherical outer surface, defining 6 circular dividing lines on said spherical outer surface, the improvement comprising:
- said outer cover including two molded cover parts having respective hemispherical outer surfaces which adjoin one another along a generally circular mold parting line to define said spherical outer surface, said mold parting line being coincident with one of said 6 dividing lines, all of said dimples being arranged in nonintersecting relationship relative to said mold parting line and the dividing line coincident therewith, and the remaining 5 dividing lines each being intersected by at least one of said dimples, whereby said dimples are arranged evenly and uniformly over said spherical outer surface.

Abstract
A golf ball surface is divided into faces of an icosidodecahedron consisting of 20 regular triangles and 12 regular pentagons, each of said 20 regular triangles is subdivided into 4 small regular triangles, each of said 12 regular pentagons is subdivided into 5 isosceles triangles, 6 dividing lines of the spherical surface occur when structured as above, and on the remaining 5 dividing lines except 1 mold parting line of 6 dividing lines are crossed the dimples, said dimples aren'"'"'t crossed on the center of said regular triangles and pentagons, and said dimples intervals are arranged in a spaced circle on the basis of on the center of the respective regular triangles and pentagons.
