Abstract
Disclosed herein is a golf ball having on its surface a number of dimples and a number of edges separating dimples from each other, wherein the edges are formed from a plurality of edge elements joined together such that some of the joining parts of the edge elements assume a smoothly curved shape as viewed from above. The golf ball has improved aerodynamic performance due to dimples and achieves a long flying distance.
Claims17
A golf ball having on its surface a number of dimples and a number of edges separating dimples from each other, wherein said edges are formed from a plurality of edge elements joined together such that some of the joining parts of said edge elements assume a smoothly curved shape as viewed from above,
- wherein the dimples are formed by combination of circular dimples and non-circular dimples.
A golf ball having on its surface a number of dimples and a number of edges separating dimples from each other, wherein the dimples include non-circular dimples, and wherein said edges are formed from a plurality of edge elements joined together such that some of the joining parts of said edge elements dividing the non-circular dimples assume a smoothly curved shape as viewed from above,
- wherein the wall surface of dimples which continues from the curved joining part of the edge elements is formed in a curved shape like the curved joining part.
A golf ball having on its surface a number of dimples and a number of edges separating dimples from each other, wherein said edges are formed from a plurality of edge elements joined together such that some of the joining parts of said edge elements assume a smoothly curved shape as viewed from above,
- wherein it is hypothesized that the golf ball is a sphere having no dimples on its surface, the ratio of the space of dimples to the volume of the hypothetic sphere is 1.1 to 1.7%.
A golf ball having on its surface a number of dimples and a number of edges separating dimples from each other, wherein the dimples include non-circular dimples, and wherein said edges are formed from a plurality of edge elements joined together such that some of the joining parts of said edge elements dividing the non-circular dimples assume a smoothly curved shape as viewed from above,
- wherein each of the dimples comprises a concave bottom wall surface.
