Description

Technical Field

[0001] This utility model relates to the field of golf ball technology, specifically to a novel golf ball. Background Technology

[0002] Golf is an ideal outdoor sport where players hit a ball into a hole with a club. It is widely popular due to its beautiful scenery, fresh air, and bright sunshine, and combines the enjoyment of nature, physical exercise, and recreation. With rising living standards, golf is gradually becoming one of the most desirable luxury activities for the general public.

[0003] Based on their existing structure, golf balls can be broadly categorized into single-layer, double-layer, and multi-layered balls. Generally, the more layers a golf ball has, the farther it flies, the less prone it is to deformation, and the more expensive it is. Single-layered balls are typically used only as practice balls, double-layered balls are the most commonly used, while multi-layered golf balls are rarely used due to their high price.

[0004] Authorization announcement number CN208356042U discloses a novel golf ball with an enhanced limiting interlayer. Specifically, it discloses that a resin layer is wrapped around the core of the ball, and several pits are evenly distributed on the outer surface of the resin layer; a carbon fiber layer is added between the core of the ball and the resin layer, and an HFP resin layer is set between the carbon fiber layer and the elastic rubber layer, so as to form a corresponding elastic support between the carbon fiber layer and the HFP resin layer.

[0005] Therefore, the aforementioned novel golf ball with reinforced limiting interlayer is a multi-layered ball. However, after analysis of the shortcomings of existing golf balls by those skilled in the art, it is found that although it is a multi-layered ball, it still suffers from problems such as insufficient elasticity and speed after impact.

[0006] Therefore, based on existing technologies and verified by practical applications, this invention proposes technical solutions for further research and development and design of product structures within the same technical field. These proposed technical solutions can completely solve the problems existing in the prior art, and at the same time, they are also conducive to solving many technical problems in the same technical field. Utility Model Content

[0007] To address the problems existing in the prior art, the purpose of this utility model is to provide a new type of golf ball. By incorporating multiple gas-filled elastomers inside, pressure can be generated within the elastomers, producing elasticity. This significantly enhances the elasticity and speed of the new golf ball during impact, resulting in greater explosive power, better spin and stability, and significantly improved resistance.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] A novel golf ball includes a core layer, a first cover layer, and a second cover layer arranged sequentially from the inside out; a plurality of uniformly distributed elastomers are further disposed between the core layer and the first cover layer or between the first cover layer and the second cover layer; each elastomer has a cavity inside which is filled with gas to give the elastomer elasticity; by providing a plurality of gas-filled elastomers, the elasticity and speed of the novel golf ball can be greatly enhanced when the ball is hit.

[0010] Furthermore, the elastomer is disposed between the first cover layer and the second cover layer, and the inner surface of the second cover layer is matchedly connected to the outer surface of each of the elastomers, and the inner surface of each elastomer is matchedly connected to the outer surface of the first cover layer.

[0011] Furthermore, the elastomer is disposed between the core layer and the first cover layer, and the inner surface of the first cover layer is matchedly connected to the outer surface of each of the elastomers, and the inner surface of each of the elastomers is matchedly connected to the outer surface of the core layer.

[0012] Furthermore, the outer and inner surfaces of the elastomer are respectively arc-shaped, and the curvature of the outer surface of the elastomer is greater than that of the inner surface of the elastomer.

[0013] Furthermore, it also includes an elastic covering layer; the inner surface of each of the elastomers is connected to the outer surface of the covering layer, and the covering layer correspondingly covers the core layer or the first cover layer.

[0014] Furthermore, the elastomers are spaced apart; the height by which the elastomer protrudes outward from the covering layer is less than the thickness of the covering layer; the volume of the cavity is between one-third and two-thirds of the total volume of the elastomer, so as to ensure that the cavity can be filled with a sufficient amount of gas.

[0015] Furthermore, both the elastomer and the coating layer are made of ionomer resin.

[0016] Furthermore, the elastomer and the covering layer are integrally manufactured using 3D printing, which facilitates production.

[0017] Furthermore, when the covering layer is disposed between the first covering layer and the second covering layer, the second covering layer is fitted onto the covering layer and the elastomer by injection molding.

[0018] Furthermore, the core layer is made of high-elasticity rubber; the first cover layer is made of high-elasticity ionomer; and the second cover layer is made of polyurethane.

[0019] The beneficial effects of this utility model are as follows:

[0020] This invention incorporates multiple gas-filled elastomers inside, meaning the elastomers are hollow. By filling the cavities with a certain amount of gas, pressure is generated inside the elastomers, producing elasticity. This significantly enhances the elasticity and speed of the new golf ball during impact, resulting in greater explosive power, better spin and stability, and significantly improved resistance.

[0021] In addition, by attaching the elastomer to the elastic coating layer, the elastomer can be combined with the elasticity of the elastomer to generate sufficient elasticity for the golf ball. This can be used to further enhance the elasticity and speed of the new golf ball during impact, resulting in excellent performance. Attached Figure Description

[0031] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the scope of protection of the utility model.

[0032] Example 1:

[0033] like Figures 1-3 As shown, a novel golf ball includes a core layer 1, a first cover layer 2, and a second cover layer 3 arranged sequentially from the inside out. An elastic body 4 is also disposed between the core layer 1 and the first cover layer 2, or between the first cover layer 2 and the second cover layer 3. Specifically, each elastic body 4 has a cavity 5 inside, which is filled with gas to give the elastic body 4 elasticity. Therefore, the second cover layer 3 serves as the outer shell layer.

[0034] Therefore, by setting multiple gas-filled elastomers 4, that is, the interior of the elastomers 4 is hollow, and after filling the cavity 5 with a certain amount of gas, pressure can be generated inside the elastomers 4 and elasticity can be generated. This can be used to greatly enhance the elasticity and speed of the new golf ball when hitting the ball, making it more explosive, with better spin and stability, and significantly improved resistance.

[0035] The type of gas filled in cavity 5 can be selected according to actual production needs, as long as it is ensured that the gas filled in cavity 5 can fully enhance the elasticity and speed of the new golf ball.

[0036] In this embodiment, the elastic body 4 is disposed between the first covering layer 2 and the second covering layer 3. That is, the inner surface of the second covering layer 3 is matchedly connected to the outer surface of each elastic body 4, and the inner surface of each elastic body 4 is matchedly connected to the outer surface of the first covering layer 2. In this structure, the elastic body 4 can also provide good support for the second covering layer 2.

[0037] As a preferred embodiment, the outer and inner surfaces of the elastomer 4 are both arc-shaped, with the curvature of the outer surface being greater than that of the inner surface. This allows the outer surface of the elastomer 4 to fit snugly against the second covering layer 3, resulting in a large and very stable connection area. Of course, those skilled in the art will understand that the shape of the elastomer 4 can also be configured as a hemispherical shape or other similar forms.

[0038] Preferably, the various elastic elements 4 are spaced apart to provide good elasticity to various parts of the golf ball.

[0039] Preferably, the volume of the cavity 5 is between one-third and two-thirds of the total volume of the elastomer 4, so as to ensure that the cavity 5 is filled with a sufficient amount of gas.

[0040] Preferably, the elastomer 4 is made of an ionomer resin. Since an ionomer resin with a certain degree of elasticity is an existing material, it will not be described in detail here.

[0041] In addition, the core layer 1 is made of high-elasticity rubber; the first cover layer 2 is made of high-elasticity ionomer; and the second cover layer 3 is made of polyurethane. The aforementioned high-elasticity rubber, high-elasticity ionomer, and polyurethane are all prior art and will not be described in detail here. However, those skilled in the art should understand that other existing materials can also be used for the core layer 1, the first cover layer 2, and the second cover layer 3; specific examples will not be given here.

[0042] like Figure 1 As shown, a plurality of evenly distributed pits 6 are also provided on the outer surface of the second covering layer 3.

[0043] like Figure 1 As shown, in this embodiment, the shape of the recess 6 is set to hemispherical. Alternatively, the shape of the recess 6 can also be elliptical, square, or polygonal, etc. In specific implementations, the number of recesses 6 can be in the range of 80-120.

[0044] Example 2:

[0045] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the elastomer 4 is disposed between the core layer 1 and the first cover layer 2; that is, there is no elastomer 4 between the first cover layer 2 and the second cover layer 3. The inner surface of the first cover layer 2 is matchedly connected to the outer surface of each elastomer 4, and the inner surface of each elastomer 4 is matchedly connected to the outer surface of the first cover layer 2. In this structure, the elastomer 4 can also provide good support for the second cover layer 2.

[0046] The function of the elastomer 4 in this embodiment is the same as that of the elastomer 4 in Embodiment 1, which is to enhance the elasticity and speed of the new golf ball during impact, making it more explosive.

[0047] Example 3:

[0048] like Figure 5 and Figure 7As shown, the difference between this embodiment and Embodiment 1 is that this embodiment further includes an elastic covering layer 7; the inner surface of each elastomer 4 is connected to the outer surface of the covering layer 7, and the covering layer 7 correspondingly covers the first covering layer 2, that is, the elastomer 4 is connected to the outer surface of the first covering layer 2 through the covering layer 7. Of course, the inner surface of the second covering layer 3 is matchedly connected to the outer surfaces of the elastomer 4 and the covering layer 7. Therefore, this design allows the covering layer 7 to be used to enhance the elasticity of the golf ball. Its cooperation with the elasticity of the elastomer 4 can generate sufficient elasticity for the golf ball, thereby further enhancing the elasticity and speed of the new golf ball during impact.

[0049] To increase durability and ease of manufacturing, the second cover layer 3 is applied to the cover layer 7 and the elastomer 4 by injection molding.

[0050] In addition, the height by which the elastomer 4 protrudes outward on the covering layer 7 is less than the thickness of the covering layer 7.

[0051] The thickness of the covering layer 7 is less than the thickness of the first covering layer 2 and the second covering layer 3. The thickness of the covering layer 4 can also be set according to actual needs, such as being appropriately thickened or thinned. However, it should be noted that the thickness of the covering layer 4 should not be too thick or too thin, so as not to affect the performance of the covering layer 4.

[0052] In this embodiment, the coating layer 7 is also made of ionomer resin. Furthermore, to improve production efficiency and reduce production costs, the elastomer 4 and the coating layer 7 are integrally manufactured using 3D printing, allowing for convenient and quick production and thus improving production efficiency.

[0053] Example 4:

[0054] like Figure 6 As shown, the difference between this embodiment and Embodiment Two is that this embodiment further includes an elastic covering layer 7; the inner surface of each elastomer 4 is connected to the outer surface of the covering layer 7, and the covering layer 7 correspondingly covers the outer surface of the core layer 1, that is, the elastomer 4 is connected to the outer surface of the core layer 1 through the covering layer 7. Of course, the inner surface of the first covering layer 2 is matchedly connected to the outer surfaces of the elastomer 4 and the covering layer 7. Similarly, this design allows the covering layer 7 to be used to enhance the elasticity of the golf ball. Its cooperation with the elasticity of the elastomer 4 can generate sufficient elasticity for the golf ball, thereby further enhancing the elasticity and speed of the new golf ball during impact.

[0055] Furthermore, the coating layer 7 is also made of ionomer resin, and the elastomer 4 and the coating layer 7 are also integrally manufactured using 3D printing. The remaining characteristics of the coating layer 7 are consistent with those in Example 3, and will not be repeated here.

[0056] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
