Description

Golf Club {Golf Club}

The present invention relates to a golf club, and more particularly, by improving the elasticity and repulsive force of the golf club shaft, so that the swing angle of the club head hitting the golf ball hits the deformation track outside the existing track, thereby improving the power of the club head In addition, the present invention relates to an improved type of golf club that can improve the distance of the golf ball by straightening the direction of the club head.

In general, golf is a sport that reacts very sensitively depending on the driving shot posture of the player, swing form, the length of the golf club and the grip state of the grip, unlike other sports events.

In golf, the flying distance of the golf ball is a golfer's greatest concern, and various methods have been tried to improve the flying distance.

As one of these methods, methods for optimizing the thickness of the face of the club head have been proposed. That is, since the flying distance of a golf ball is related to the thickness of the face of a club head, the method of improving the flying distance by changing the thickness of the face of a club head is proposed.

For example, the thicker the thickness of the face of the club head, the greater the sponge effect. Therefore, the distance of the golf ball naturally becomes shorter and vice versa, so that methods of reducing the thickness of the face are proposed. have.

However, if the thickness of the face becomes thin, cracks or breakage may occur due to fatigue phenomenon due to the concentrated stroke or brittleness due to the injection molding of the club head. Therefore, there is a limit to thinning the face thickness. In addition, the thickness having a predetermined strength and hardness that can withstand the impact load is selected.

That is, a specific method for increasing the distance while having an appropriate face thickness has not been proposed yet.

As is generally known, the golf club is configured to fix the head portion 10 to the lower end of the hollow shaft 20 as shown in FIG. 1 and to fit the grip portion 30 around the upper end of the shaft 20.

The shaft 20 may be made of various materials, such as light weight titanium or tungsten, or carbon graphite.

Shaft 20 of carbon graphite material is usually produced by rolling a carbon fabric in a columnar mold, heating it to a high temperature in a furnace, cooling and curing it, and then removing the mold.

In the conventional golf club as described above, the shaft 20 is manufactured in a cylindrical shape.

On the other hand, golf clubs are one of the technical challenges to minimize the distortion during swing and impact to ensure that the ball is sent in the desired direction, while sending the ball farther, and even if the golfer accidentally hit the ground while swinging the shaft High strength is required so that it does not break.

However, the conventional golf club has only a cylindrical body on the shaft and does not have a reinforcement function, so when the ball swings back down from the top swing state by impacting the ball when the ball is impacted, it is retracted by the bending of the shaft 20 at the moment of hitting the ball. The ball is pushed out by pushing the ball. At this time, the restoring force is weak and the propulsion force is shortened and the flying distance is shortened. There was a problem that can not send the ball exactly.

When hitting a golf ball with a golf club, it is known that it is effective to increase the head speed in order to extend the flying distance of the golf ball.

When the golf player swings the golf club, the head is bent by slowing down the head position, and the head is accelerated by rotating the wrist to make up for the slowing of the head from tens of centimeters before the hit position to the hit position. Can be improved.

At the moment when the head of the golf club strikes the golf ball, it is preferable that the face surface of the head is returned to the corresponding position on the shaft axis in view of efficiently transmitting the hit energy to the golf ball.

Fig. 2 is a diagram showing the behavior when the golf ball is hit by a golf club, and shows the state when the head H provided at the tip of the shaft S contacts the golf ball B. Figs.

As shown in Fig. 2, when the golf ball B is hit by the golf club, the head H receives the recoil of the impact from the golf ball B, so that the front end side of the shaft S (shaft on the drawing) At the position where S1 (lower side of S) is relatively advanced in the rotational direction, a phenomenon occurs that the shaft S is bent.

This phenomenon becomes a factor of energy loss when transferring the hitting energy to the golf ball B, which causes the flying distance of the golf ball B to decrease.

Therefore, when the face surface F of the head H hits the golf ball B, the curvature of the front end side S1 of the shaft S is suppressed and the axis line and the face surface F of the shaft S are restrained. It is preferable to position it on the vertical line L shown by the dotted line in FIG. 2 because a hit energy is efficiently given to the golf ball B. FIG.

The present invention improves the elasticity and repulsion of the shaft (S) when the face surface (F) of the club head (H) hit the golf ball (B) to improve the disadvantages of the prior art of the club head hitting the golf ball The swing angle has been improved so that it can hit the modified track beyond the existing track.
