Tetrahedral dimple pattern golf ball |
摘要 |
A golf ball including two poles and an equator is characterized by the arrangement of a preselected number of dimples in a geometrical lattice configuration based upon a subdivided tetrahedron on the surface thereof The lattice includes six dimple-free great circles around the circumference of the ball, one of the circles corresponding with the equator and another of the circles passing through the poles. All of the circles define twenty-four generally equivalent triangles, twelve in each hemisphere of the ball. An equal number of dimples are arranged within each of the triangles, and the dimple arrangement in at least two of the triangles is different from the dimple arrangement in the remaining triangles. |
