A dimple pattern (dimple pattern) of a golf ball and a dimple arrangement structure

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement structure of dimples formed on the outer surface of a golf ball in a golf ball and a dimple pattern serving as a reference for determining the arrangement structure of the dimples.;The dimple pattern of the present invention is composed of 8 octagons and 8 octagons.;Each of the octagons is formed by one square and four triangles, and one side of the triangle is formed by coinciding the four sides of one square.;The triangle is formed of a s surrounded by the octagonal section and a part of the equatorial line.;The octagonal shape geometrically divides the outer surface of the golf ball to form octagonal and octagonal spherical shapes that are not octagonal and octagonal in plan view. Therefore, since eight octagons are formed on the outer surface of one golf ball, one square has 6 squares, 24 triangles, and 8 octagons.;The dimples are provided in three kinds of sizes of 0.013, 0.145, and 0.150 inches. The dimples of 0.13 inches are placed inside the triangles and the squares. Some dimples are laid over the bevels of the triangles. The dimples of 0.150 inches and 0.145 Inches of dimples are arranged along nine sides of an octagonal shape so that both dimples alternate and dimples of 0.145 inches are arranged inside the array of dimples.;Further, an array structure different from the above array structure may be formed. That is, the dimples are provided in six types having diameters of 0.075, 0.125, 0.125, 0.150, 0.155, and 0.160 inches, and 0.160 inch dimples are placed inside the quadrangle. The 0.075 inch dimple and the 0.15 inch dimple are arranged in a nine-And a 0.15 inch dimple 0.15 inch dimple or a 0.155 inch dimple is arranged inside the array of the 0.15 inch dimple.
