Golf ball

摘要

Disclosed is a golf ball in which a plurality of dimples is arranged. The golf ball includes first dimples having the largest diameter and second dimples having the second largest diameter arranged on the surface of the golf ball divided into a spherical rhombic dodecahedron, the first dimples are arranged in an LF region of a radius of π/10 radian ±10% around a first apex of the spherical rhombic dodecahedron, shared jointly by 4 spherical rhombi, and the second dimples are arranged in an LS region of a radius of π/20 radian ±10% around a second apex of the spherical rhombic dodecahedron, shared jointly by 3 spherical rhombi. Thereby, air flow and pressure drag are uniformized in all of spherical polygons and thus, a carry distance of the golf ball may be improved.

1. A golf ball in which a plurality of dimples is arranged, comprising first dimples having a first diameter and second dimples having a second diameter arranged on a surface of the golf ball divided into a spherical rhombic dodecahedron,
wherein the first dimples are arranged in a plurality of circular first regions, each circular first region of the plurality of circular first regions having a first radius of 5% of a circumference of the golf ball ±10% located on each first apex of a plurality of first apexes of the spherical rhombic dodecahedron, each first apex being shared jointly by 4 spherical rhombi of the spherical rhombic dodecahedron, and the second dimples are arranged in a plurality of circular second regions, each circular second region of the plurality of circular second regions having a second radius of 2.5% of the circumference of the golf ball ±10% located on each second apex of a plurality of second apexes of the spherical rhombic dodecahedron, each second apex being shared jointly by 3 spherical rhombi of the spherical rhombic dodecahedron.
