发明名称 Golf ball
摘要 A golf ball construction wherein the dimples are evenly distributed over the surface to minimize the appearance and effect of an unbroken seam line. The dimples are arranged in three different patterns comprising a pentagon formation at each of the poles, five equally-spaced trapezoid formations in each hemisphere located between the pentagon pattern and the equator, and five equally-spaced triangular formations interposed between the trapezoid formations. The diameter of the dimples is also controlled to maintain the uniformity of the spacing.
