Abstract

(57) [Problem] To extend the spin duration of a golf ball by an inertia effect. SOLUTION: A filament of a shape memory superelastic alloy has a mesh structure.
And cover and cover the spherical structure core.
Alternatively, a golf ball structure in which a spherical core is wrapped and covered with a filament of a shape memory superelastic alloy.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention provides a specific gravity difference between the inner core of the internal structural core of the golf ball and the inside of the cover.

[0002]

[Prior art]

 Currently, commercially available golf balls have a core structure, called a center core or a liquid center, in which a core rubber structure is wound around a thread rubber and covered, or a two-layer or three-layer spherical structure made of a synthetic resin material. It is made by forming and covering the core. Others use a synthetic resin material with a heavy metal powder distributed in the intermediate structure layer.

[0003]

[Problems to be solved by the invention]

 By adopting the structure of the present invention, the inertia effect of the golf ball is activated, the spin time of the launched golf ball is prolonged, and good flight results can be obtained.

[0004]

[Means for Solving the Problems]

 As a means of extending the spin time, which is the subject of the present invention, a filament of a shape memory superelastic alloy is combined with a core of a spherical structure close to the cover of the golf ball so that the launched golf ball will fly due to the inertial effect. Is the means to solve the problem.

[0005]

[Embodiment of the invention]

 According to an aspect of the present invention, in a golf ball formation structure, a golf ball is formed by forming a net or mesh with a filament of a shape memory superelastic alloy, covering a spherical structure core close to a skin cover of the golf ball, and covering the core. Make a ball. Alternatively, a golf ball is made by wrapping a spherical core with a shape memory superelastic alloy filament and covering it. In these cases, adjust the weight of the spherical core to complete the total weight of the golf ball as defined in the Golf Rules.

[0006]

【Example】

 Depending on the composition density of the net and mesh structures composed of the filaments of the shape memory superelastic alloy of the present invention, there is a degree of freedom to make various types of golf balls according to the purpose.

[0007]

[Effect of the invention]

 The present invention is based on the assumption that the specific gravity of the shape memory superelastic alloy fiber that is formed close to the ball cover is assumed to be about 6.5 g, which is higher than the ball-forming substance, and the rotational inertia effect when flying. This increases the spin time and gives good flight results.

[Embodiment of the invention]

According to an aspect of the present invention, in a golf ball formation structure, a spherical structure core close to a golf ball outer cover is covered and covered with a mesh structure made of filaments of a shape memory superelastic alloy. Make a golf ball. Alternatively, a golf ball is made by wrapping a sphere structure core with filaments of a shape memory superelastic alloy and covering it. In these cases, adjust the weight of the spherical core so that the total weight of the golf ball is as specified in the Golf Rules.
