Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a golf club in which the length of a shaft can be adjusted.

[0002]

[Prior Art]

 Golf clubs usually consist of three parts: a grip, a shaft, and a head, and among them, they are classified into wood clubs and iron clubs depending on the type of head. There are many types of golf clubs with different head sizes and loft sizes to change the flight distance of the ball. Specifically, there are 1 to 5 woods and 1 to 9 irons in order of increasing flight distance. In addition to these clubs, there are sand wedges that launch golf balls from bunker, pitching wedges that are used for approach shots on the green, and putters that roll the golf ball toward the cup. It is a general practice to use the competition properly from the inside as needed.

[0003]

[Problems to be solved by the device]

 Therefore, when a player plays a conventional golf club, first, the golf club corresponding to the target distance to the green is selected and used. However, the distance settings for each hole on the golf course vary widely, and it is not possible for a golf club with less than nine golf clubs to handle it. Therefore, competitors select and use the golf club with the flight distance that they think is closest to the target distance, but for beginners and unskilled players, the maximum effect is obtained within the range of the selected golf club's ability. For this reason, it is extremely difficult to swing while precisely determining the grip of the grip and adjusting the club head speed delicately, and as a result, there is a problem that accurate play cannot be performed. Furthermore, since the length of the shaft of a golf club is determined for each number, it may not be the optimum size depending on the height of the athlete, and it is even more difficult to swing, especially when playing from a rough rough surface. There was also the problem of doing it. Therefore, the golf club of the present invention has been made to solve the above problems.Even beginners can easily perform an optimum swing when hitting a golf ball, and further The purpose is to provide golf clubs corresponding to the state of the green.

[0004]

[Means for Solving the Problems]

 The present invention made to achieve the above object is a golf club including a grip, a shaft, a neck portion, and a head, wherein the shaft and the grip are independent members, and the inside of the grip is The gist of a golf club is characterized by including a shaft length adjusting member that adjusts the length of the shaft by sliding the upper end of the shaft in the length direction of the grip. The shaft length adjusting member consists of a long bolt that rotatably penetrates from the outside of the upper part of the grip to the inside, and a nut fixed to the upper end of the shaft.The shaft part of the bolt has an inner diameter part of the nut. It is preferable that it is screwed.

[0005]

[Action]

 According to the golf club of the present invention, when the bolt (shaft length adjusting member) in the grip is rotated, the nut (shaft length adjusting member) screwed to the shaft portion of the bolt moves. Then, since the nut is fixed to the upper end of the shaft, the shaft slides in the grip from the upper end as the nut moves. Due to this action, the length of the shaft becomes shorter or longer depending on the rotating direction of the bolt.

[0006]

【Example】

 An embodiment of the golf club of the present invention will be described with reference to the drawings. In the golf club of this embodiment, as shown in FIG. 1, a head 1 as a hitting portion for hitting the golf club, and a shaft 3 having a hexagonal cross section is connected to one end of the head 1 via a neck portion 2. A grip 4 is detachably attached to the upper portion of the shaft 3. As shown in FIG. 2, the upper end 3a of the shaft 3 is provided with a guide sleeve 3b into which the lower end of a pipe 4a, which is the core material of the grip 4, is fitted, and the guide sleeve 3b is provided inside the guide sleeve 3b. The shaft portion 5a of the bolt 5 is inserted from the outside of the upper portion of the grip 4 and two nuts 6 and 7 threadedly threaded through the grip 4 are continuously fixed.

Next, the operation and effect of the golf club of this embodiment will be described with reference to the drawings. 4 and 5 are partially cutaway cross-sectional views showing the connection between the grip 4 and the shaft 3 of the golf club of this embodiment. As shown in FIG. 4, in the golf club of the present embodiment, the shaft portion 5a of the bolt inserted in the pipe 4a of the grip 4 has the inside of the shaft 3 through the nut 7 fixed to the upper end portion 3a of the shaft 3. It is designed to penetrate. Therefore, when the head portion 5b of the bolt is rotated, the nut 7 screwed to the shaft portion 5a of the bolt moves up and down, so that the shaft 3 also slides vertically in the pipe 4a of the grip 3. The length of the shaft 3 of the golf club expands and contracts. In addition, FIG. 5 shows a state in which the length of the shaft 3 is minimized by tightening the nut head 5b clockwise. Further, in the present embodiment, the head portion 5b of the bolt 5 of the grip 4 is described in a bare state, but if the rotating ring 9 as shown in FIG. 6 can be attached / detached, the operability is further improved.

As described above, in the golf club of this embodiment, the length of the shaft 3 can be freely adjusted by the bolt 5 provided in the grip 4 and the nut 7 connected to the shaft 3. .. This allows athletes to improve the skills of beginners and inexperienced players by changing the length of the shaft 3 of the golf club according to their skill, body shape, field condition and individual play style. You will be able to enjoy playing golf. Further, even for a professional golf player, the merit associated with the change in the length of the shaft 3 can be tolerated, and the golf club is a very useful golf club, which leads to further improvement of the technique as a professional.

[0009]

[Effect of the device]

 As described above in detail, in the golf club of the present invention, the shaft and the grip are independent members, and the upper end of the shaft is slid in the grip in the length direction of the grip to increase the length of the shaft. The shaft length adjusting member for adjusting is provided, and further, the shaft length adjusting member is composed of a long bolt rotatably penetrating from the upper outside of the grip to the inside, and a nut fixed to the upper end of the shaft, The length of the shaft can be freely adjusted by screwing the shaft of the bolt onto the inner diameter of the nut. As a result, athletes can improve the skills of beginners and inexperienced players by changing the length of the golf club shaft according to their skills, body shape, field conditions and individual place tiles. You will be able to enjoy playing golf. Furthermore, it is a very useful idea for a professional golf player, as it can set the merits according to the change in the length of the shaft tolerantly and further improve the technique as a professional.
