Description

Technical Field

[0001] The present invention relates to the technical field of golf balls, in particular to a new type of golf ball. Background Art

[0002] Golf is an ideal outdoor ball sport in which a ball is hit into a hole with a stick. It is widely favored by people for its beautiful scenery, fresh air, bright sunshine and other characteristics. It is also a sport that combines the enjoyment of nature, physical exercise and games. With the increasing consumption level of people, golf has gradually become one of the most ideal luxury items for the public in the future.

[0003] According to the existing golf ball structure, it can be basically divided into single-layer balls, double-layer balls or multi-layer balls, etc. Generally speaking, the more layers a golf ball has, the farther it flies, the less likely it is to deform, and the more expensive it is. Single-layer balls are generally only used as practice balls, double-layer balls are the most commonly used balls, and multi-layer golf balls are rarely used because of their high price.

[0004] Authorization announcement number CN208356042U discloses a new type of golf ball with an enhanced limiting interlayer, which specifically discloses that a resin layer is wrapped around the outer periphery of the sphere core, and a plurality of pits are evenly distributed on the outer surface of the resin layer; a carbon fiber layer is added between the sphere core and the resin layer, and an HFP resin layer is arranged between the carbon fiber layer and the elastic rubber layer, so that corresponding elastic support is formed between the carbon fiber layer and the HFP resin layer.

[0005] It can be seen that the new golf ball with enhanced limiting interlayer is a multi-layer ball. However, after analyzing the defects of the existing golf ball by those skilled in the art, although it is a multi-layer ball, it still has the problems of insufficient elasticity and insufficient speed after hitting the ball.

[0006] Therefore, the present invention, based on the existing technology and combined with the verification of practical applications, proposes technical solutions for further research and development and design of product structures in the same technical field. These proposed technical solutions can completely solve the problems existing in the existing technology, and are also conducive to the solution of many technical problems in the same technical field. Summary of the invention

[0007] In view of the problems existing in the above prior art, the purpose of the present invention is to provide a new type of golf ball, which, by arranging a plurality of gas-filled elastomers inside, can generate pressure and elastic force inside the elastomers, which can be used to greatly enhance the elasticity and speed of the new type of golf ball when hitting the ball, making it more explosive, more rotating and more stable, and significantly improving resistance.

[0008] In order to achieve the above object, the technical solution of the present invention is:

[0009] A new type of golf ball comprises an inner core layer, a first covering layer and a second covering layer which are arranged in sequence from the inside to the outside; a plurality of evenly distributed elastomers are arranged between the inner core layer and the first covering layer or between the first covering layer and the second covering layer; a cavity is arranged inside each of the elastomers and is filled with gas so that the elastomer has elastic force; a plurality of evenly distributed pits are arranged on the outer surface of the second covering layer; by arranging a plurality of the elastomers filled with gas, the elasticity and speed of the new type of golf ball can be greatly enhanced when hitting the ball.

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

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

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

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

[0014] Furthermore, the elastomers are spaced apart from each other; the height of the elastomer protruding outward from the coating layer is less than the thickness of the coating layer; the volume of the cavity occupies between one third and two thirds of the total volume of the elastomer to ensure that a sufficient amount of gas can be filled in the cavity.

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

[0016] Furthermore, the elastomer and the coating layer are integrally manufactured by 3D printing, thereby facilitating production and manufacturing.

[0017] Further, when the coating layer is disposed between the first covering layer and the second covering layer, the second covering layer is matched and covered on the coating layer and the elastomer by injection molding.

[0018] Furthermore, the inner core layer is made of high-elastic rubber; the first covering layer is made of high-elastic ion polymer; and the second covering layer is made of polyurethane.

[0019] The beneficial effects of the present invention are:

[0020] The present invention arranges a plurality of elastic bodies filled with gas inside, that is, the inside of the elastic body is hollow, and after a certain amount of gas is filled in the cavity, pressure and elastic force can be generated inside the elastic body, which can be used to greatly enhance the elasticity and speed of the new golf ball when hitting the ball, making it more explosive, more rotatable and more stable, and significantly improving resistance.

[0021] In addition, the elastomer is connected to the elastic covering layer so that it can cooperate with the elasticity of the elastomer to generate sufficient elastic force for the golf ball, which can be used to further enhance the elasticity and speed of the new golf ball when hitting the ball, and the use effect is good.

[0031] The invention is further described below in conjunction with the accompanying drawings and specific embodiments. The following description is only exemplary and does not limit the protection scope of the invention.

[0032] Embodiment 1:

[0033] like Figure 1-Figure 3 As shown, a new type of golf ball includes a core layer 1, a first cover layer 2 and a second cover layer 3 arranged in sequence from the inside to the outside; an elastic elastomer 4 is also arranged 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, a cavity 5 is arranged inside each elastomer 4 and the cavity 5 is filled with gas to make the elastomer 4 have elastic force; a plurality of evenly distributed pits 6 are arranged on the outer surface of the second cover layer 3. Therefore, the second cover layer 3 is used as a surface shell layer.

[0034] Therefore, the present invention provides a plurality of gas-filled elastic bodies 4, that is, the interior of the elastic body 4 is hollow, and after a certain amount of gas is filled in the cavity 5, pressure and elastic force can be generated inside the elastic body 4, which can be used to greatly enhance the elasticity and speed of the new golf ball when hitting the ball, making it more explosive, more rotatable and more stable, and significantly improving resistance.

[0035] As for the type of gas filled in the cavity 5, a suitable gas can be selected according to actual production needs, and it is only necessary to ensure that the gas filled in the cavity 5 is able to fully enhance the elasticity and speed of the new golf ball.

[0036] In this embodiment, the elastomer 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 matched and connected to the outer surface of each elastomer 4, and the inner surface of each elastomer 4 is matched and connected to the outer surface of the first covering layer 2. Under this structure, the elastomer 4 can also play a good supporting role for the second covering layer 2.

[0037] As a preferred embodiment, the outer surface and the inner surface of the elastic body 4 are arc-shaped, and the arc of the outer surface of the elastic body 4 is greater than the arc of the inner surface of the elastic body 4, so that the outer surface of the elastic body 4 can be matched and fitted with the second cover layer 3, and the connection area is large and very stable. Of course, those skilled in the art should know that the shape of the elastic body 4 can also be set to a hemispherical shape or the like.

[0038] Preferably, the elastic bodies 4 are arranged at intervals to provide good elasticity for various positions of the golf ball.

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

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

[0041] In addition, the inner core layer 1 is made of high elastic rubber; the first cover layer 2 is made of high elastic ion polymer; and the second cover layer 3 is made of polyurethane. The above-mentioned high elastic rubber, high elastic ion polymer and polyurethane are all prior art and will not be introduced in detail here. However, those skilled in the art should know that for the material selection of the inner core layer 1, the first cover layer 2 and the second cover layer 3, they can also use other existing materials, which will not be specifically exemplified here.

[0042] like Figure 1 As shown, in the present embodiment, the shape of the pit 6 is set to be hemispherical. In addition, the shape of the pit 6 can also be set to be elliptical, square or polygonal, etc. In specific implementation, the number of the pits 6 can be implemented as a numerical value in the range of 80-120.

[0043] Embodiment 2:

[0044] like Figure 4 As shown, the difference between this embodiment and the first embodiment is that, in this embodiment, the elastomer 4 is arranged between the core layer 1 and the first cover layer 2, that is, no elastomer 4 is arranged between the first cover layer 2 and the second cover layer 3. The inner surface of the first cover layer 2 is matched and connected to the outer surface of each elastomer 4, and the inner surface of each elastomer 4 is matched and connected to the outer surface of the first cover layer 2. Under this structure, the elastomer 4 can also play a good supporting role for the second cover layer 2.

[0045] The function of the elastic body 4 in this embodiment is consistent with that of the elastic body 4 in the first embodiment, both of which are used to enhance the elasticity and speed of the new golf ball when hitting the ball, making it more explosive.

[0046] Embodiment three:

[0047] like Figure 5 and Figure 7As shown, the difference between this embodiment and the first embodiment is that, in this embodiment, an elastic coating layer 7 is further included; the inner surface of each elastic body 4 is connected to the outer surface of the coating layer 7, and the coating layer 7 is correspondingly coated on the first covering layer 2, that is, the elastic body 4 is connected to the outer surface of the first covering layer 2 through the coating layer 7. Of course, the inner surface of the second covering layer 3 is matchedly connected to the outer surfaces of the elastic body 4 and the coating layer 7. Therefore, this design allows the coating layer 7 to be used to enhance the elasticity of the golf ball, and the combination of the coating layer 7 and the elasticity of the elastic body 4 can well generate sufficient elasticity for the golf ball, so that it can be used to further enhance the elasticity and speed of the new golf ball when hitting the ball.

[0048] In order to increase firmness and facilitate production, the second covering layer 3 is matched and covered on the coating layer 7 and the elastomer 4 by injection molding.

[0049] In addition, the height of the elastic body 4 protruding outward on the coating layer 7 is smaller than the thickness of the coating layer 7 .

[0050] The thickness of the coating layer 7 is respectively less than the thickness of the first covering layer 2 and the second covering layer 3. The thickness of the coating layer 4 can also be set according to actual needs, for example, it can be appropriately thickened or thinned, but it should be noted that the thickness of the coating layer 4 should not be too thick or too thin, so as not to affect the use effect of the coating layer 4.

[0051] In this embodiment, the coating layer 7 is also made of ionomer resin. In addition, in order to improve production efficiency and reduce production costs, the elastomer 4 and the coating layer 7 are made of 3D printing, so that they can be produced conveniently and quickly to improve production efficiency.

[0052] Embodiment 4:

[0053] like Figure 6 As shown, the difference between this embodiment and the second embodiment is that, in this embodiment, an elastic coating layer 7 is further included; the inner surface of each elastomer 4 is connected to the outer surface of the coating layer 7, and the coating layer 7 is correspondingly coated on 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 coating layer 7. Of course, at this time, the inner surface of the first covering layer 2 is matched and connected to the outer surfaces of the elastomer 4 and the coating layer 7. Similarly, this design allows the coating layer 7 to be used to enhance the elasticity of the golf ball. The coating layer 7 cooperates with the elasticity of the elastomer 4 to generate sufficient elasticity for the golf ball, so that it can be used to further enhance the elasticity and speed of the new golf ball when hitting the ball.

[0054] In addition, the coating layer 7 is also made of ionomer resin, and the elastomer 4 and the coating layer 7 are also made by 3D printing. The remaining characteristics of the coating layer 7 are consistent with those in the third embodiment, and will not be repeated here.

[0055] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
