摘要: In a dimpled golf ball, the parameters of dimples are optimized to improve the aerodynamic performance of the ball and thus increase its flight distance. The dimples have a planar shape which is circular, and are of at least three types of mutually differing diameter. At least one of the types of dimples has a cross-sectional shape differing from that of the other types. One of the dimple types may have a cross-sectional shape defined by the union of at least two concave portions of differing slope.

摘要: When the spherical surface of a golf ball is divided into a plurality of substantially congruent spherical triangles, dimples are substantially equally distributed in the spherical triangles. The spherical triangles are minimum triangular units which are substantially congruent with each other. The dimples distributed in each minimum triangular unit include crossing dimples that each lie across a side of the minimum triangular unit. The total of the crossing lengths of the crossing dimples is 70-80% of the total side length of the minimum triangular unit. The golf ball is improved in the symmetry of elevation angle and carry, and has good aerodynamic performance and an increased total flight distance.

摘要: A golf ball has plural types of dimples on a spherical surface, which is assumed to be a regular icosahedron having twenty triangles. Apexes of five triangles join together at a vertex. Those dimples arranged in each triangle constitute an arrangement unit. A first dimple having a smallest diameter is located at the vertex, and second dimples having a greater diameter are equidistantly arranged around the first dimple. When a pentagon which circumscribes the second dimples is drawn, an average depth of those dimples located within the pentagon is up to 85% of the average depth of those dimples located in the remaining areas.
