The present invention relates to a golf club for practice, and more particularly, the adjacent portion of the head portion of the shaft is folded at the back swing and gradually returned to its original position at the down swing, and at the impact to ensure that the shaft is straightened to strike the ball by straightening By allowing the impact to be possible only in the posture, you can practice the correct posture of the swing, and by increasing the force applied to the ball at impact, it is possible to make a strong impact while using a real golf club.

As is well known, golf is a game that determines the level of how many strokes a golf ball puts in a predetermined hole cup, and the angle of inclination of the head with respect to the shaft for the same swing force in order to accurately hole in fewer strokes. Loft), many golf clubs, such as wood or iron, are used to make the distance appear differently depending on the trajectory.

In other words, wood has a low trajectory according to its material characteristics, so there is almost no loft, so the ball goes straight with straightness, and the iron is made of steel, and the ballistic is large and the loft angle is large so that the ball flies closer. For example, the wood is used to send the golf ball away and the iron is used to send the golf ball at the correct distance. Therefore, the golfer avoids obstacles and calculates the distance to use the golf club selectively.

On the other hand, it is important to correctly select the golf club according to the distance and terrain remaining in the golf game, but the long distance when hitting the ball and the correct direction of the batting is basically required.

There are many factors that can improve the accuracy and distance of the ball, but one of the most important is the golfer's swing posture and the correct impact when hitting the ball. If you hit the ball exactly at the center of the face, you can maintain the accuracy of the ball and improve the flying distance.However, for beginners, it is very difficult to accurately hit the ball at the center of the face of the clubhead. It is required.

However, beginners do not know the exact posture when swinging or know the correct posture during the swing, but the posture is often distracted when they swing. As a result, most of them are being taught by professionals while paying high lesson fees, which is an obstacle to popularizing golf.

In addition, although the golf exerciser is widely distributed in the market, it is not only to learn the technique of catching a golf club and randomly hitting the ball through these golf exercisers, but also to learn the actual correct swing posture and the exact impact of the golf ball. No, there is a limit to its functionality.

The present invention has been proposed in view of such a point, and from the position in which the shaft is extended to the head adjacent to the shaft, the swinging portion of the head and the lower end of the shaft is configured to be hinged 120 degrees in the direction of bending backwards at the time of the backswing to the golf club backswing. When the lower end of the head and shaft is bent backwards and gradually spreads during downswing, the shaft is fully extended at the time of impact, so that the accurate impact is possible, and in the case of paloslow, the practice golf club can be maintained to improve the accuracy of the batting. It is to provide.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The practice golf club according to the present invention, as shown in Figs. 1 and 2, the handle grip, the head (2) hitting the golf ball, the shaft connecting the grip (1) and the head (2) In the golf club consisting of (3), the hinge portion 100 constitutes a head adjacent portion of the shaft (3), the hinge portion (100) of the head (2) and the shaft from the position where the shaft (3) is extended The lower end of (3) is configured to be rotatable 120 ° in the direction of bending backward during the backswing.

At this time, the hinge portion 100 is fixed to the head (2) side of the divided portion of the lower end of the shaft (3), the hinge pin 101 in the center of the first rotational portion 110 is installed mandrel; It is fixed to the grip 1 side of the divided part of the lower end of the shaft 3, the diameter and width are larger than the 1st rotation part 110, and the middle of the side wall surface is the same width as the 1st rotation part 110, and the shaft 3 The sliding contact surface 121, which is open to 0 ° to 120 ° based on the longitudinal direction of the inner side, is identical to the outer diameter of the first rotating part 110 in the concentric circle with the outer rim thereof, and hinge pins 101 are formed at both center portions. ) Is composed of a mandrel and the second rotating unit 120 installed with the first rotating unit (110).

Referring to the operation of the golf club for practice according to the invention configured as described above are as follows.

First, when the first swing back swing is performed, the first rotating part 110 connected to the lower end of the shaft 3 of the head 2 is slid along the sliding contact surface 121 inside the second rotating part 120 to the rear. The bending angle is limited to 120 ° according to the shape of the second rotating part 120.

At this time, if the lower ends of the head 2 and the shaft 3 are bent more than 120 °, the centrifugal force will increase, but there is a possibility that the head 2 and the shaft 3 cannot be straightened at impact, and the head 2 and the shaft ( If the lower end of 3) is bent at less than 90 ° bar centrifugal force is reduced and there is a disadvantage that can not exert a force at impact, the practice golf club according to the present invention is to be able to be folded up to 120 ° but the user to his body You can backswing appropriately to have a bending angle of more than 90 ° and less than 120 °.

When the downswing in such a state, the lower ends of the head 2 and the shaft 3, which were bent backwards, are gradually extended, and at impact, the shaft 3 is straightened to hit the golf ball. It is made of palosuro with the shaft 3 straightened. If this swing posture is not done properly, it is difficult to hit the ball. Even if the ball is hit, a hook or slice is produced, and the back ground or the upper part of the ball is hit, or a swing swing is made. Done.

Therefore, the user can immediately recognize that there is a problem in his swing posture when the golf ball is not hit properly when using the practice golf club according to the present invention so that the hitting can be made properly, the posture of the back swing, the time of the down swing Posture, impact posture, paloslowy posture, finish posture, etc. You can correct yourself by feeling whether you are correct or not, and if you practice with this corrected posture, you will have a proper swing posture naturally on your body. Even if a regular golf club is used, it is possible to make an accurate impact through the correct swing posture.

In addition, the lower end of the head (2) and the shaft (3), which was bent backwards at the time of the backswing, will be unfolded as it is gradually rotated at the time of the downswing, so the impact strength is improved by more than 30% by using the centrifugal force at impact. As a result, the user can directly feel the impact of the impact while gradually gaining confidence in the way to give strength at impact, and if you practice countlessly with these practice golf clubs The technology is naturally doubled to the user's body, even if you use a normal golf club, the distance of the batting is increased as well as the direction is very good.

On the other hand, if the lower end of the head (2) and the shaft (3) is turned sideways instead of rotating the hinge pin (101) of the hinge portion (110) only in one direction at the time of the backswing and downswing, no matter how good the swing posture The hook or slice is bound to fly, but the hinge portion 100 of the practice golf club according to the present invention has a first rotational portion 110 connected to the head 3 side shaft 3 on the grip 1 side shaft 3. The first rotating part is accommodated inside the connected second rotating part 120 and is in sliding contact along the sliding contact surface 121, and the second rotating part 120 has a larger diameter than the first rotating part 110. The shaft 3 connected with the 110 may be supported by the open side surface of the second rotating part so that the lower end of the head 2 and the shaft 3 are not twisted, and the hinge pin 101 of the hinge part 100 is provided. It can only be rotated in one direction about its axis. Therefore, the practice golf club according to the present invention is accurate impact is possible only if the swing posture is made, the distance of the batting is extended, the direction is also good.

In addition, the practice golf club according to the present invention has the advantage that the straight shaft (3) at the time of impact can be maintained in the Palos Rossi as it is to maintain the straightness of the golf ball in the direction of the impact at impact.

4 is a view showing another embodiment of the present invention, wherein the first rotation part 110 is fixed to the head 2 side of the divided portion of the lower end of the shaft 3 and the hinge pin 101 is installed in the center thereof; It is fixed to the grip 1 side of the divided part of the lower end of the shaft 3, the diameter and width are larger than the 1st rotation part 110, and the middle of the side wall surface is the same width as the 1st rotation part 110, and the shaft 3 The bearing receiving groove 122 is formed larger than the outer diameter of the first rotating part 110 in the concentric circumference with the outer edge therein is opened to 0 ° ~ 120 ° based on the longitudinal direction of the), the bearing receiving groove 122 There are a plurality of bearings 123 are installed to contact the outer diameter portion of the first rotating part 110, the hinge pin 101 is hinged with the second rotating part 120 installed in a mandrel together with the first rotating part 110 in both central portions. The branch part 100 is configured, and in this way, the lower end of the shaft 3 including the head 2 can be brought into rolling contact with the bearing 123 while having the same effect as that of the embodiment of the present invention. There is an advantage to doing this.
