Description

Technical Field

[0001] The present invention relates to the technical field of golf balls, and in particular to an improved golf ball. Background Art

[0002] Golf, commonly known as the little white ball, is a sport with special charm. It is an activity for people to exercise their bodies, cultivate their sentiments, and improve their skills in a natural and elegant green environment. Playing golf is to use different golf clubs to hit a golf ball into a hole.

[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] Application publication number CN102294110A discloses a golf ball, which specifically discloses that it includes a core layer and at least two intermediate layers that sequentially wrap the core layer, and a shell layer that surrounds the intermediate layer; the shell layer has a thickness of 0.8 to 1.4 mm and a hardness (unit: Shore D) of 40 to 50; the first intermediate layer closest to the shell layer among the intermediate layers has a thickness of 1.0 to 2.0 mm and a hardness (unit: Shore D) of 50 to 65; the remaining intermediate layers immediately below the first intermediate layer have a thickness of 1.3 to 15 mm and a hardness (unit: Shore D) of 30 to 70; the radius length of the core layer is 5 to 18 mm and a hardness (unit: Shore D) of 30 to 70; the moment of inertia value of the golf ball is less than 83 g·cm2.

[0005] It can be seen that the golf ball is a multi-layer ball. However, the overall design of the golf ball still has the problem that the elasticity and speed when hitting the ball are not good enough. Therefore, it is necessary to improve the prior art. Summary of the invention

[0006] In view of the problems existing in the above prior art, the purpose of the present invention is to provide an improved golf ball, which can increase the softness of the coating layer by setting a plurality of evenly distributed through holes on a coating layer, so as to make the deformation effect better, thereby improving the elasticity and speed of the golf ball when hitting the ball, and also helping to increase the initial velocity and flight distance of the golf ball.

[0007] In order to achieve the above object, the technical solution of the present invention is:

[0008] An improved 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; an elastic covering layer is also arranged between the inner core layer and the first covering layer or between the first covering layer and the second covering layer; the covering layer is provided with a plurality of evenly distributed perforations which penetrate the inner surface and the outer surface of the covering layer; the outer surface of the second covering layer is provided with a plurality of evenly distributed pits; by providing a plurality of the perforations on the covering layer, the softness of the covering layer can be increased, so that the deformation effect is good, and the elasticity and speed of the golf ball can be improved when hitting the ball, which is also beneficial to increase the initial speed and flight distance of the golf ball.

[0009] Furthermore, when the coating layer is located between the inner core layer and the first covering layer, a plurality of bosses that can be matchably inserted into the plurality of perforations protrude from the inner surface of the first covering layer, and the inner surface of the first covering layer matchably abuts against the outer surface of the coating layer; the provision of the bosses is beneficial in improving the connection stability between the coating layer and the first covering layer, so that the coating layer can stably feed back the elastic force to the first covering layer.

[0010] Furthermore, the protrusion passes through the through hole and is connected to the surface of the inner core layer. This structure is relatively stable.

[0011] Furthermore, when the covering layer is located between the first covering layer and the second covering layer, a plurality of bosses that can be matchably inserted into the plurality of perforations protrude from the inner surface of the second covering layer, and the inner surface of the second covering layer matchably abuts against the inner surface of the covering layer; the provision of the bosses is helpful in improving the connection stability between the covering layer and the second covering layer, so that the covering layer can stably feed back the elastic force to the second covering layer.

[0012] Furthermore, the protruding column passes through the through hole and is connected to the outer surface of the first covering layer. This structure is also relatively stable.

[0013] Furthermore, the through hole and the protruding column are both cylindrical.

[0014] Furthermore, the coating layer is made of ionomer resin.

[0015] 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.

[0016] Furthermore, the thickness of the cladding layer is smaller than the thickness of the first covering layer and the second covering layer respectively.

[0017] Furthermore, the shape of the pit is hemispherical.

[0018] The beneficial effects of the present invention are:

[0019] The present invention provides a plurality of evenly distributed perforations on the coating layer, thereby increasing the softness of the coating layer and improving its deformation effect, thereby improving the elasticity and speed of the golf ball, and also facilitating increasing the initial velocity and flight distance of the golf ball.

[0020] In addition, by providing a convex column that can be plugged into the through hole on the inner surface of the covering layer, not only can the stability of the structure be ensured, but also the elastic force can be stably fed back to the outer layer, so that the golf ball can have better elasticity and speed.

[0030] 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.

[0031] Embodiment 1:

[0032] like Figure 1-Figure 4As shown, an improved golf ball comprises 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 covering layer 4 is 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; a plurality of evenly distributed through holes 5 are arranged on the covering layer 4 and penetrate the inner surface and the outer surface of the covering layer 4; a plurality of evenly distributed dimples 7 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.

[0033] Therefore, the present invention provides a plurality of evenly distributed perforations 5 on the covering layer 4, thereby increasing the softness of the covering layer 4 and improving its deformation effect, thereby improving the elasticity and speed of the golf ball when hitting the ball, and also helping to increase the initial velocity and flight distance of the golf ball.

[0034] In this embodiment, the covering layer 4 is disposed between the inner core layer 1 and the first covering layer 2 , so that the covering layer 4 can support the first covering layer 2 while facilitating the transmission of the elastic force outward.

[0035] In this embodiment, the coating layer 4 is made of ionomer resin. Since the ionomer resin with a certain elasticity is an existing material, it is not described in detail here. In addition, in order to improve production efficiency and reduce production costs, the coating layer 4 is made of 3D printing, so that it can be produced conveniently and quickly to improve production efficiency.

[0036] Preferably, 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. Since the above-mentioned high elastic rubber, high elastic ion polymer and polyurethane are all prior art, they 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.

[0037] like Figure 3 As shown, in this embodiment, the thickness of the coating layer 4 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 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.

[0038] like Figure 1 As shown, in the present embodiment, the shape of the pit 7 is set to be hemispherical. In addition, the shape of the pit 7 can also be set to be elliptical, square or polygonal shapes. In specific implementation, the number of the pits 7 can be implemented as a numerical value in the range of 80-120.

[0039] Embodiment 2:

[0040] like Figure 5 As shown, the difference between this embodiment and the first embodiment is that, in this embodiment, the covering layer 4 is arranged between the first covering layer 2 and the second covering layer 3, so that the covering layer 4 can support the second covering layer 3 while transmitting the elastic force outward.

[0041] Embodiment three:

[0042] like Figure 6 As shown, the difference between this embodiment and the first embodiment is that, in this embodiment, when the coating layer 4 is located between the core layer 1 and the first covering layer 2, that is, the coating layer 4 is not arranged between the first covering layer 2 and the second covering layer 3; a plurality of protrusions 6 which can be matched and inserted into a plurality of through holes 5 are protruded on the inner surface of the first covering layer 2, and the inner surface of the first covering layer 2 is matched and abutted against the outer surface of the coating layer 4.

[0043] Therefore, the provision of the protruding column 6 is helpful to improve the connection stability between the covering layer 4 and the first covering layer 2, so that the covering layer 4 can stably feed back the elastic force to the first covering layer 2 and allow the golf ball to have better elasticity and speed.

[0044] In addition, in order to ensure stability, each protrusion 6 is connected to the surface of the inner core layer 1 after passing through the through hole 5. This structure is not only stable, but also can well transmit the elastic force of the inner core layer 1 to the outside.

[0045] Preferably, the shapes of the perforations 5 and the bosses 6 can both be set to be cylindrical. Of course, their shapes can also be set to other shapes accordingly if necessary.

[0046] Embodiment 4:

[0047] like Figure 7 As shown, the difference between this embodiment and the first and third embodiments is that, in this embodiment, when the coating layer 4 is located between the first covering layer 2 and the second covering layer 3, that is, the coating layer 4 is not arranged between the inner core layer 1 and the first covering layer 2; a plurality of protrusions 6 which can be matched and inserted into a plurality of through holes 5 are protruded on the inner surface of the second covering layer 3, and the inner surface of the second covering layer 3 is matched and abutted against the inner surface of the coating layer 4.

[0048] Similarly, the provision of the protruding column 6 is also beneficial to improving the connection stability between the covering layer 4 and the second covering layer 3, so that the covering layer 4 can stably feed back the elastic force to the second covering layer 3 and allow the golf ball to have better elasticity and speed.

[0049] In order to ensure stability, each protrusion 6 is also connected to the outer surface of the first covering layer 2 after passing through the through hole 5. This structure is stable and can better transmit the elastic force to the outside.

[0050] More specifically, in this embodiment, the second covering layer 3 is matched and attached to the covering layer 4 by injection molding, so that the second covering layer 3 and the covering layer 4 can be stably connected.

[0051] 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.
