[Technical field to which the device belongs]

 The present invention relates to a hollow club head composed mainly of a club head, a striking face plate, a weight, and a weight ring, and more particularly to a hollow head structure of an iron golf club capable of adjusting the weight to a position suitable for each golf player.

[0002]

[Prior art]

 Golf clubs have two types of club heads: wooden clubs and iron clubs. The Taiwanese official gazette discloses many weights for changing the position of the center of gravity in wooden clubs. For example, there are utility models such as publication numbers: 189451, 189995, 245974, 256102. Since the wooden club head has a relatively large volume and a large usable space inside, the weight can be easily arranged inside the head. The design of the weight arrangement of the wooden clubs can be adjusted inside the clubs by a mechanism inside the clubs, as in the case of a practical model such as Taiwan Official No .: 216920, 229455, 255205.

However, iron club heads are limited in volume and weight, and the space available for them is also limited. Therefore, how to design a golf club head having the best placement of the center of gravity is determined by the manufacturer. Is a difficult task. Among the known manufacturing methods, there are utility models of Taiwan publication numbers: 181481, 250695, 2252355.

[Problems to be solved by the device]

 The position of the center of gravity of the golf club head is caused by the LD value and the inertia torque. The LD value is a value obtained by multiplying the center-of-gravity distance L-value (distance from the club-head center-of-gravity point to the club axial center) by the center-of-gravity depth D-value (distance from the club-head center of gravity to the striking surface), and the direction in which the ball is projected And the accuracy of the refraction angle. The inertia torque (the distance from the axis of the club to the center of gravity of the club head when the club is swung) is related to the distance the ball travels.

Therefore, a manufacturer of golf club heads is deeply researching the LD value and the inertia torque to manufacture a better product. However, because the club head hits the ball differently due to the difference in the way the individual holds the club and the swinging motion of the club, the requirements for the center of gravity of the club head used differ. In order for club head manufacturers to manufacture club heads with different center of gravity according to the requirements of each user, it is necessary to use countless molds or make them by hand, which is a very expensive product and is unrealistic. Target. Even if it is unavoidable to design some club heads with different center of gravity positions and let the golf player choose the golf player, the golf player will swing the club's habit of holding the club according to the selected club. It is necessary to change the behavior. Alternatively, by applying weight to the club head, the error caused by how to hold the club and the action of swinging the club is corrected. However, this does not provide a fundamental solution to the problem.

In addition, generally, in order to apply weight to the club head, a method of attaching a weight or a method of fixing to the head with a screw is used. With these methods, the weight drops off or loosens due to vibrations and improper attachment that occur when hit, resulting in poor quality reliability. In addition, iron club heads are being replaced with hollow heads like wooden club heads in order to reduce vibration when hit. Taiwan Public Notice No .: 221741, as shown in Figure 6, Figure 7, Figure 8 and Figure 9, how to limit the weight of the iron club head and the strength of the club head in a limited space. A new research topic for club head manufacturers is whether to obtain a relatively large hollow portion.

A main object of the present invention is to provide a golf club head, and effectively solve the problem of the center of gravity of the iron club head.

[0008]

[Means for Solving the Problems]

 The present invention for solving the above-mentioned problems adopts means according to claim 1. According to this procedure, a front tank is provided in the striking section mainly composed of the club head and a striking face plate is attached thereto, and a rear tank is also provided on the back side of the striking section to allow the weight to be attached. The central parts of the front and rear tanks penetrate. In addition, a front fitting groove is provided from the bottom of the front tank to the periphery of the club head main body, and the striking face plate is fitted. Similarly, from the side wall of the rear tank, a rear fitting groove is provided on the periphery toward the main body of the club head, and a weight is fitted to fix the weight. With such a design, by adjusting the specific gravity of the striking face plate, the weight, and the weight ring, it is possible to arrange various positions of the center of gravity of the club heads manufactured from the same mold, which can be selected by various golf players. . In addition, the weight ring can adjust the weight position by changing the distribution of its thickness.

[Embodiment of device]

 As shown in FIGS. 1, 2 and 5, the present invention provides a club head main body 10, a striking face plate 20 made of a material different from the specific gravity of the club head main body 10, a weight 30, and a weight ring 40. Etc. The striking part of the club head main body 10 is provided with a front tank 11 (see FIGS. 1 and 3) to which a striking face plate 20 is attached, and the rear tank 12 (see FIG. 2, FIG. 2) on the back side of the club head main body 10 facing the striking part. 3), so that the weight 30 can be attached. The central portions of the front tank 11 and the rear tank 12 penetrate. Further, a front fitting groove 111 is provided on the peripheral edge of the front tank 11 toward the club head main body 10, and the striking face plate 20 is fitted therein. Further, a rear fitting groove 121 is provided on the peripheral edge of the rear tank 12 toward the main body of the head, and a weight ring 40 is fitted therein to fix the weight 30.

The striking face plate 20 is made of a material having a relatively low specific gravity such as aluminum, titanium, or an alloy thereof when it is desired to move the center of gravity of the club head behind. When the center of gravity of the club head is moved to the front, lead, copper and Select a material with a relatively high specific gravity such as the alloy. The outer shell of the striking face plate 20 and the outer shell of the front tank 11 of the club head main body 10 are the same, and leg portions 21 are provided outward from the bottom of the outer edge of the striking face plate 20 (see FIGS. 1 and 4). Furthermore, the thickness and outer contour of the leg portion 21 are the same as the thickness and outer contour of the front fitting groove 111 of the front tank 11, and these parts can be tightly fitted (see FIG. 6). Since the club head main body 10 and the striking face plate 20 cannot be fitted at room temperature, the striking face plate 20 is inserted after heating the club head main body 10 to make the front tank 11 large, and when the club head main body 10 is gradually cooled, The leg portion 21 of 20 is fitted into the front fitting groove 111, so that the striking face plate 20 and the club head main body 10 are closely joined.

For the weight 30, a material having a relatively low specific gravity is selected when the center of gravity of the club head is desired to be in the front, and a material having a relatively high specific gravity is selected when the center of gravity is moved to the rear. The outer shell of the weight 30 and the outer shell of the rear tank 12 of the club head 10 are the same. The weight 30 is mounted in the rear tank 12 of the club head main body 10, and the upper surface of the weight 30 and the bottom surface of the rear fitting groove 121 are The holes 13 of the club head main body 10 are exactly aligned and closed to form a hollow state (see FIG. 6).

On the other hand, for the weight ring 40, a material having a relatively high specific gravity is selected when the center of gravity of the club head is moved backward, and a material having a relatively low specific gravity is selected when moving the center of gravity forward. The outer shape of the weight ring 40 and the outer shape of the rear tank 12 of the club head main body 10 have the same ring shape. Further, the leg portion 41 extends outwardly from the bottom edge of the weight ring 40 (see A in FIGS. 2 and 7), and the thickness and outer contour of the leg portion 41 are the rear fitting groove 121 of the side wall of the front tank 12. The thickness and contour of the shell, so that when the parts are fitted tightly together, the weight 30 is fixed (see FIG. 6). Since the club head main body 10 and the weight ring 40 cannot be fitted at room temperature, be sure to heat the club head main body 10 to increase the size of the rear tank 12, and then add the weight 30 and then the weight ring 40. When the club head main body 10 is cooled, the leg portion 41 of the weight ring 40 is fitted into the rear fitting groove 121, the weight ring 40 and the club head main body 10 are tightly coupled, and the weight 30 is fixed. Also, as shown in FIGS. 2, 7 and 8, the weight ring of the present invention has the same thickness in a normal cross section (see FIG. 7A and FIG. 8A), but it is necessary for the user. The thickness can be changed accordingly. For example, if you want to raise the center of gravity of the club head slightly, thicken the upper part of the weight ring 40 (see B in FIG. 7), and if you want to lower the center of gravity of the club head slightly, thicken the lower part of the weight ring 40 (Fig. 7C), the center of gravity of the club head can be moved inward or outward by making one of both sides of the weight ring thicker (see B and C in FIG. 8).

Since the club head of the present invention has a large hollow volume and the striking face plate has both excellent elasticity and strength, the vibration generated at the moment when the ball hits the club head can be suppressed more than that of the conventional golf club. it can. Moreover, the center of gravity arrangement is determined by adjusting the striking face plate, weight and weight ring having different specific gravities, and widens the selection of the material of parts. Therefore, the selectivity for arranging the center of gravity of the club head in manufacturing is greater than the conventional one without changing the main structure of the club head main body and other parts. Also, golf players can use the club head of the present invention to better suit their hitting habits.
