Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: To provide a structure for connecting a head and a shaft of a golf club, which allows a hit ball to fly accurately for a long time and which does not cause a movement disorder of a hitter. A neck is cut to an appropriate height, and an inner hole of the original neck is extended downward toward the inside of the head, thereby lowering the center of gravity of the head main body and extending the hitting distance. In addition, the inner hole of the neck is made larger than the conventional one, and a metal connecting device having a flange whose outer diameter is gradually increased downward is provided at the upper end of the cylinder. It fits in the inner hole and reduces the vibration transmitted to the shaft at the time of striking, so that the user's hand, arm, and elbow do not have a movement disorder.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a golf club head-shaft connecting structure.

[0002]

[Prior art]

 Golf clubs are used with no more than several tens depending on the function and location, but since each club has a special function and design, the hitter must make an appropriate selection. Good results can be achieved for the first time. That is, the golf club is used properly for each specific scene, and the par can be achieved when the combination of the proper use is appropriate. In normal play, the player who hits the hole with a small number of hits wins the game. Therefore, it is important to hit the ball accurately and as close to the hole as possible. To do this, lower the center of gravity of the head, and combine this with the correct swing posture of the hand and elbow.

Most current clubs have a long tubular neck at the joint with the head shaft (as shown in FIG. 1), and since the center of gravity of the head main body is relatively high, the hitter swings to swing the ball. The flight angle when striking was not good (as in Fig. 2), so we could not fly the ideal distance.

Further, generally, when the shaft is coupled to the neck, an adhesive is applied between the neck and the shaft to directly bring them into contact with each other. For this reason, the vibration of the shaft directly hits the user's hand. It may be transmitted to the arms and elbows and cause movement disorders.

Further, since the conventional neck has a long tubular shape, the resistance of the wind to the neck upon striking is large, and therefore the flight distance cannot be extended.

[0006]

[Problems to be solved by the device]

 The present invention makes it possible to lower the center of gravity of the golf club head, thus enabling the ball to be struck far and accurately, reduce the vibration of the shaft at the time of hitting, and prevent movement obstacles. The challenge is to provide a connection structure.

[0007]

[Means for Solving the Problems]

 The connection structure of the head and shaft of the golf club of the present invention has the neck cut to an appropriate height, the inner hole of the neck is made larger than the original diameter, and it extends downward toward the inside of the head, and A metal connecting device with a flange that gradually increases in outer diameter is used as a cushioning member to apply adhesive to the inner and outer peripheries of the device, then insert it into the inner hole of the neck, and at the same time make a metal cushion. The shank is inserted into the inner hole of the member.

[0008]

[Embodiment of device]

 The golf club head-shaft connecting structure of the present invention has the neck cut to an appropriate height, and the inner hole of the original neck is extended downward toward the inside of the head. To lower the ball and extend the hitting distance. In addition, the inner hole of the neck was made larger than the conventional one, and a metal connecting device with a flange with the outer diameter gradually increasing downward at the upper end of the cylinder was used as a cushioning member and the adhesive was applied to the outer and inner circumferences. After that, the shaft is inserted into the inner hole of the metal connecting device while being fitted into the inner hole of the neck, thereby reducing the vibration transmitted to the shaft at the time of striking. Do not cause movement disorders in the arms and elbows.

[0009]

【Example】

 As shown in FIGS. 3 and 3, according to the present invention, the neck 100 of the connecting portion 10 of the head 1 is cut to an appropriate position, and the inner hole 101 of the original neck is extended downward, The center of gravity 102 is lowered to extend the flight distance of the ball when hit (as shown in FIG. 4). Further, the inner hole 101 is made larger than the conventional one, and a flange having a gradually increasing outer diameter is provided at the upper end of the cylinder, and the metal shock absorbing member 3 into which the shank 2 is fitted is used as a connecting device in the inner hole 101. To attach.

As shown in FIG. 5, the golf club head-shaft connecting structure according to the present invention includes an adhesive 4 inside the inner hole 101 and an inner periphery 30 and an outer periphery 31 of the metal cushioning member 3. And the lower end of the shank 2 is inserted into the metal buffer member 3 as well as the metal buffer member 3 is inserted into the inner hole 101. By installing the metal cushioning member 3, the vibration transmitted to the shank 2 at the time of impact is reduced, and the occurrence of movement disorder to the user's hand, arm or elbow is reduced.

FIG. 6 shows another embodiment of the present invention. In this embodiment, the neck 500 of the connecting portion 50 of the other type of head 5 is cut to an appropriate position, and the original After the inner hole 501 of the neck is expanded and extended to the inside of the head 5, the metal buffer member 6 having the inner hole 60 is further inserted into the inner hole 501, and then the inner hole 6 of the metal buffer member 6 is inserted. Insert the shaft 7 into 0. The combination method is the same as that of the above-mentioned embodiment, so that further description will be omitted.

[0012]

[Effect of device]

 In the golf club head-shaft connection structure of the present invention, the center of gravity of the head body is lowered by cutting the neck to an appropriate height and extending the inner hole of the neck downward toward the inside of the head. Therefore, it is possible to extend the flight distance of the ball, and by inserting one metal cushioning member into the inner hole of the neck and assembling the shaft to the head through the metal cushioning member Vibrations are dampened by the metallic cushioning member to reduce shaft vibrations and thus reduce movement disorders in the user's hands, arms and elbows.
