Golf Ball

Abstract

[Problem to be solved] To provide a golf ball with improved flight distance due to improvement in aerodynamic properties by means of contriving dimple designs. The golf ball is in the shape of a sphere and is composed of dimples and lands excluding dimples, wherein said dimples are formed by elliptical dimples together with circular dimples, wherein one said elliptical dimple overlaps said circular dimples at both end parts in its major axis direction, said circular dimples and said elliptical dimples are connected with each other, and one said land is formed between three said elliptical dimples.

What is claimed is: 
     
         1 . A golf ball in which the surface of a sphere is composed of dimples and lands excluding dimples, wherein said dimples are formed by elliptical dimples together with circular dimples, wherein one said elliptical dimple overlaps said circular dimples at both end parts in its major axis direction, respectively, said circular dimples and said elliptical dimples are connected with each other, and one said land is formed between three said elliptical dimples. 
     
     
         2 . The golf ball according to the scope of  claim 1  wherein the maximum depth of the overlapping portion of said circular dimples and said elliptical dimples is 0.1 to 0.15 mm, the maximum depth of the central portion of said circular dimples is 0.23 to 0.28 mm, and the maximum depth of the central portion of said elliptical dimples is 0.33 to 0.38 mm.
