Abstract
Description
Technical Field
[0001] The present application relates to a golf club shaft structure, and more particularly to a golf club shaft structure that combines the advantages of two different materials, metal and carbon fiber, and can give the shaft good elasticity and strong toughness, making the long-range and precision of the swing process easy to control. Background Art
[0002] Golf clubs are used in different ways according to different hitting requirements, so the club heads on golf clubs will also have different designs. For example, the initial "swing" should make the ball fall closer to the hole on the green, so the shape of the club head will be different from the "putt" design that is already near the hole on the green. There are many innovative structures in the design of such club heads. As for the shaft of golf clubs, from the early metal material manufacturing to the carbon fiber material manufacturing, to the current metal material plus carbon fiber material manufacturing, it is constantly being improved to provide more diverse choices for golf enthusiasts.
[0003] However, when the shaft of the golf club is used for "putting" and "swinging", the user's own feel and strength are very important for the accuracy and stability of ball control. In addition to regular practice, the influence of the coordination between the head and shaft materials of the golf club is also directly related. For example, if the shaft is made of metal material because it is heavier, the rolling stability of the trajectory after hitting the ball after "putting" or "swinging" is better (but the rolling or flying distance of the ball is shorter); if the shaft is made of carbon fiber material because it is lighter, the rolling or flying distance of the ball after hitting the ball after "putting" or "swinging" is longer (but the rolling stability of the trajectory of the ball is worse). Based on this, it seems that individuals can achieve ideal ball control by choosing a suitable shaft (metal material or carbon fiber material) according to the center of gravity and strength of their own hitting posture. However, it is difficult for beginners who like golf to choose a suitable shaft (metal or carbon fiber) according to the center of gravity and strength of their own hitting posture. Although experienced players can choose a shaft that suits their own use, due to the limitation that the shaft is made of metal or carbon fiber, the rolling of the ball after hitting the ball as expected by "putting" or "swinging" is not easy to control, especially the trajectory rolling stability or long-range and accuracy during the "swinging" process are even more difficult to control.
[0004] Furthermore, the shaft of the golf club is made of metal and carbon fiber. Although it provides another choice for golfers, it seems to be able to play the characteristics of the metal and carbon fiber materials, but in fact it is not the case. Please cooperate with Figure 1It is further understood that the structure of the shaft 5 includes: an inner carbon fiber layer 51 and an outer metal layer 52, wherein the carbon fiber layer 51 is composed of carbon fibers with different angles; the metal layer 52 is spirally wound around the outer surface of the carbon fiber layer 51 with metal wires, so there is a gap between the inner carbon fiber layer 51 and the metal layer 52 of the overall structure. As a result, the rolling of the ball after hitting the ball as expected by "putting" or "swinging" is also difficult to control, especially the stability or distance and accuracy of the trajectory rolling during the "swinging" process are also difficult to control. The main reason is that after hitting the ball, the force on the carbon fiber layer 51 of the entire shaft 5 is only partially absorbed by the metal layer 52 spirally wound around the outer surface of the carbon fiber layer 51 with metal wires, and most of the force penetrates and explodes from the existing gaps in the metal wires, and the metal wires added to the outer surface of the carbon fiber layer 51 cannot achieve the effect of effectively absorbing the impact force when hitting the ball, and the ball control effect on the golf ball is basically equivalent to that before winding.
[0005] In view of this, the applicant has developed this application based on his experience in composite material research for many years. Utility Model Content
[0006] The technical problem to be solved by the present application is to provide a shaft structure of a golf club, which has the characteristics of both metal and carbon fiber materials, and can give the shaft good elasticity and strong toughness. The metal material adopts a thin sheet design and a full covering setting, which can not only effectively solve the interlayer peeling between the contact surfaces of different materials, but also can provide comprehensive and effective absorption of the force impact when the ball is hit, instead of the problem of the prior art that the force penetrates through the gap by spirally winding the metal wire and cannot absorb the force impact, thereby making the long-range and precision of the golf club swing process easy to control.
[0007] In order to achieve the above-mentioned purpose, the shaft structure of the golf club of the present application includes: a main body, which is a hollow body with two ends. The main body is coated with a layer of metal sheet material. After the metal sheet material is coated on the main body, the overall transverse cross-section is similar to a tree ring structure. In this way, one end of the metal sheet material after being coated on the main body is connected to the handle; the other end is connected to the club head, which can provide the golf club with good elasticity and strong toughness.
[0008] According to the above characteristics, the metal sheet material is fully coated on the main body, and the thickness of the metal sheet material is less than 0.4mm. The metal sheet material can effectively solve the interlayer peeling caused by the extremely different expansion coefficients between the coated different materials, that is, the relatively small volume change of the metal sheet material. When the coated object is a carbon fiber material, the metal sheet material will produce relatively small interlayer peeling stress, which can effectively solve the interlayer peeling between the contact surfaces of different materials (carbon fiber material and metal material). On the contrary, an overly thick metal layer cannot solve the significant impact caused by the interlayer peeling of the contact surface. Therefore, the thickness of the metal sheet material of the present application is set to be less than 0.4mm, which can make the bonding between the mutually bonded surfaces of the coated different materials stable.
[0009] A further improvement scheme for the shaft structure of the golf club of the present application is that the body is coated with at least one layer of mutually stacked metal sheet material and carbon fiber material, that is, the at least one layer of metal sheet material and carbon fiber material are fully coated on the body, and the overall transverse cross-section is similar to a tree ring structure.
[0010] According to the features of the above-mentioned improvement schemes, the material of the metal sheet can be selected from one of aluminum, aluminum alloy, copper, steel, titanium, titanium alloy, and magnesium-aluminum alloy, and its thickness is less than 0.4 mm.
[0011] According to the features of the above-mentioned improved solutions, when the mutually stacked metal sheet material and carbon fiber material are stacked in multiple layers, the outermost layer is the carbon fiber material, and when the metal sheet material is repeatedly stacked, the thickness of the repeated stacking is less than 0.4 mm.
[0012] According to the characteristics of each of the above-mentioned improvement schemes, when the mutually stacked metal sheet material and carbon fiber material are stacked in multiple layers, the outermost layer is the layer of metal sheet material, and when the metal sheet material has repeated stacking, the thickness of the repeated stacking is less than 0.4 mm.

[0025] The positional relationships described in the following embodiments include: up, down, left and right. Unless otherwise specified, they are all based on the directions in which the components are drawn in the drawings.
[0026] See also Figure 2 The first embodiment of the golf club with the shaft structure of the golf club of the present application is a three-dimensional diagram. As shown in the figure, the golf club 1 has a shaft 2 of the present application. The structure of the shaft 2 includes: the body 20 is a hollow body with two ends 21 and 22, which are made of stacked carbon fibers. The body 20 is coated with at least one layer of metal sheet material 23 ( Figures 3 to 5 ), the metal sheet material 23 after being coated on the body 20 has a transverse cross-section similar to a growth ring structure, which can provide the body 20 with better toughness. When the metal sheet material 23 is coated on the body 20, one end 21 of the body 20 is used to be assembled with the handle 3 (as shown by the dotted line); the other end 22 is used to be assembled with the club head 42 (as shown by the dotted line).
[0027] For further structural features of the shaft 2 of this application, please refer to Figure 3The main body 20 is coated with a layer of metal sheet material 23 and carbon fiber material 24, that is, the layer of carbon fiber material 24 and the layer of metal sheet material 23 are fully coated on the main body 20, and the overall transverse cross-section is similar to a tree ring structure, wherein the layer of metal sheet material 23 can be selected from one of aluminum, aluminum alloy, copper, steel, titanium, titanium alloy, and magnesium aluminum alloy, and its thickness is less than 0.4mm. The layer of carbon fiber material 24 is coated on the metal sheet material 23, and the thickness of the layer of carbon fiber material is greater than that of the layer of metal sheet material 23. If the expansion coefficient difference between the layer of carbon fiber material 24 and the layer of metal sheet material 23 is set, the volume change of the metal sheet material 23 is relatively small, so the interlayer peeling stress generated by the volume change of the carbon fiber layer 24 and the metal layer 23 is relatively small, which can effectively solve the interlayer peeling between the contact surfaces of different materials. On the contrary, an excessively thick metal layer cannot solve the significant impact caused by interlayer peeling on the contact surface, thereby making the bonding between the carbon fiber material 24 and the metal sheet material 23 more stable. In addition, the body 20 is made of carbon fiber material, and if the metal sheet material 23 and carbon fiber material 24 are coated on the body 20 of the present application, the shaft 2 can be provided with better elasticity and toughness.
[0028] Therefore, the shaft 2 structure of the golf club of the present application has the characteristics of combining the advantages of two different materials, namely, metal material and carbon fiber material, as described above, which can give the shaft 2 good elasticity and strong toughness, making it easy to control the long-range and accuracy of the swing process. That is, the outside of the body 20 of the golf club of the present application is fully covered by the layer of carbon fiber material 24 and the layer of metal sheet material 23, which can provide the easy control of the rolling of the ball after hitting the ball as expected by "putting" or "swinging", especially the trajectory rolling stability or long-range and accuracy during the "swinging" process are also easy to control.
[0029] See also Figure 4 , Figure 5 2 are cross-sectional views of the second and third embodiments of the shaft structure of the golf club of the present application. Figure 4 As shown in FIG. 5 , the body 20 ′ and 20 ″ structure of the golf club shaft 2 ′ and 2 ″ of the present application, wherein the mutually fully laminated metal sheet materials 23 ′ and 23 ″ and the carbon fiber materials 24 ′ and 24 ″ are more multi-layered than the aforementioned first embodiment, that is, the metal sheet materials 23 ′ and the carbon fiber materials 24 ′ are alternately laminated, and after being coated on the body 20 ′ and 20 ″, the overall transverse cross-section is similar to a tree ring structure, which can give the shaft 2 ′, 2 ″ good elasticity and strong toughness, so as to achieve the effect of making the long-range and precise swing process easy to control.
