 The present invention relates to a three-layer golf ball structure. In particular, a three-layer golf that can extend the life of a golf ball, improve the feel of impact, and extend the flight distance, especially with a kind of intermediate layer made of a composite and formed material of a thermosetting elastic body and an amorphous metal alloy Related to ball structure.

[Prior art]

 The sport of golf requires not only good hitting techniques but also good tools. Among these tools, there are various types of golf balls. For a three-layer golf ball, which is one type of golf ball, three factors determine its superiority. The first is the feeling of impact. Since the ball has an excellent hit feeling, the hitter can control the direction of the hit ball. The second is the speed of rotation. The ball does not roll unnecessarily after dropping because of its longer flight distance and better suction on the ground by responding to external conditions. Third is strength. The higher the strength of the ball, the longer its life.

A known three-layer golf ball 1 shown in FIG. 1 includes a core 11, an intermediate layer 12, and an outer shell 13. The core 11 is made of a highly elastic aggregate as a main material, and various kinds of high-performance compounding agents are added to the core 11 to form a composite. The elastic body is formed by wrapping a rubber thread around the core 11 multiple times. The layer 12 is formed. The outer shell 13 is made of an ionized resin material. The three-layer golf ball 1 of this type of material has a better hit feeling and good ball control compared to the two-layer golf ball, but has a high rotation speed, and therefore has a tendency to stick to the ground. Is good, but the flight distance is inferior. In addition, since the intermediate layer 12 is formed by winding a rubber thread, its strength is low, and the rubber thread is easily detached from the core 11 when it is strongly hit. That is, the intermediate layer 12 forms a detachment. For this reason, durability is low, and an abnormal sound is emitted at the moment of impact.

On the other hand, a known three-layer golf ball 2 shown in FIG. 2 is constituted by a core 21, an intermediate layer 22, and an outer shell 23. The core 11 is a resilient body mainly composed of a high elasticity aggregate, and added and compounded with various kinds of high-performance compounding agents. The intermediate layer 22 is made of a thermoplastic elastic material. The outer shell 23 is made of an ionized resin material similarly to the conventional product. The three-layer golf ball 2 of this type of material has relatively excellent strength because the intermediate layer 22 has a real core structure of a thermoplastic elastic body. In addition, the flight distance is superior to that of the conventional product. However, since the flexibility of the mid layer 22 is inferior to that of the conventional product in which the rubber thread is wound, even if the flight distance is increased, the suction to the ground is inferior to the conventional product. Thus, both known two types of golf balls need to be improved.

[Problems to be solved by the invention]

 SUMMARY OF THE INVENTION In order to improve various disadvantages of the above-mentioned known structure, an object of the present invention is to provide a structure of a three-layer golf ball. That is, the intermediate layer is made of a composite material of a thermo-solid elastic body and an amorphous metal alloy to enhance the strength of the ball. This not only improves the durability but also reduces the energy transmission loss and increases the flight distance. Further, by adjusting the content of the amorphous metal alloy in the intermediate layer, the specific gravity is adjusted, thereby adjusting the rotation speed of the ball, and achieving the best combination at the time of hitting.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides the following three-layer golf ball structure. It mainly consists of a core, an intermediate layer and an outer shell. The core is a resilient body composed of a heat solid material as a main material, added with various kinds of high-performance compounding materials, and combined, and the outer shell is made of an ionized resin material. The intermediate layer is made of a composite material of a hot solid elastic body and an amorphous metal alloy, and has high strength and high elasticity. Further, since the content of the amorphous metal alloy can be adjusted, the specific gravity is adjusted according to the content of the amorphous metal alloy, and balls having various different specific gravities are manufactured.

[0007]

[Embodiment of the invention]

 As shown in FIG. 3, the present invention mainly includes a core 31, an intermediate layer 32, and an outer shell 33. The core 31 is a resilient body which is formed by adding and combining various kinds of high performance compounding materials with a heat solid material as a main material. The intermediate layer 32 is made of a composite material of a thermo-solid elastic body and an amorphous metal alloy, and the outer shell 33 is made of an ionized resin material. The difference between the structure of the present invention and the conventional product is that the intermediate layer 32 is manufactured using different materials. The intermediate layer 32 of the present invention is a material formed by combining a thermo-solid elastic body and an amorphous metal alloy. Since the synthetic material is a material having high strength and high elasticity, and further includes a metal component, the intermediate layer 32 naturally has high strength and high elasticity. Therefore, the molecules of the intermediate layer 32 are tighter, and the moment the club hits the ball, the ball is pressed and the resilience due to the ball's stability is further increased. In other words, the transmission loss of energy after the club hits the ball is relatively small, and the flight distance of the ball can be extended. In addition, since the content of the amorphous metal alloy in the metal material in the intermediate layer 32 can be changed at will, the specific gravity can be adjusted depending on the content of the amorphous metal alloy to produce balls having various different specific gravities. it can. That is, since the specific gravity is related to the rotation speed of the ball, balls having different rotation speeds can be manufactured. The rotation speed affects the flight distance and the sticking to the ground. For this reason, the improvement of the structure of the mid layer 32 of the present invention allows the player to select a ball having a rotation speed suitable for various conditions of the golf course to be played, and to play in the best combination. In this way, you can naturally achieve the best hitting effect and achieve good results.

[Effect of the invention]

 The present invention not only can improve the drawbacks of the known three-layer golf ball by improving the intermediate layer of the three-layer golf ball, but also at the same time, has an excellent hit feeling and good ball control. It is a whole new idea with creativity and inventiveness that can maintain the characteristics and enhance the overall quality of the ball.
