Description

The shaft sticking of training ball}

The present invention relates to a practice ball for removing and attaching a shaft, and in particular, by attaching a practice ball formed of a heavy rubber material to the shaft of a golf club to increase the weight of the head so that the golf practicer can accurately match the swing impact, and golf The present invention relates to a practice ball for detaching and attaching a shaft, which allows the exerciser to swing with confidence in actual field practice, as well as increase the power of the swing by practice, thereby increasing the distance of the golf ball.

In general, golf is a sport that requires a variety of supplies, equipment, among which the club is particularly important (clup), there are three types of clubs, wood, iron, putter, Each one is used in various ways, but basically it is divided into a club in which wood is blown, a club in which iron is attached sideways, and a club in which putter is put.

In addition, the club is divided into a grip (grip) for holding the other end with the head (head) for hitting the golf ball on the other end around the shaft forming a predetermined length, most beginners are more head than the weight of the grip portion Heavy clubs are used because they focus more on the practice and swing of flying away, while maintaining some orientation rather than precise orientation.

Therefore, beginners who practice power swinging as above will have two or three golf clubs and practice swings when warming up to loosen their body before the start of golf. It became.

However, although the player's power may be increased according to the practice swing as described above, by holding and practicing a number of clubs at the same time instead of one club to be used in practice, the sense of the club used in the actual game is deteriorated. There is a lack of sophistication and the impact is not accurate.

Therefore, due to the inaccurate impact as described above, there was a problem such as shortening the flying distance.

In order to solve the above problems, conventionally, a training club equipped with a training ball having a predetermined weight as one end of a shaft to which a head is attached is intended to increase power according to a swing.

However, in the case of the practice club as described above is used only for practice swings in practice in the actual club is provided differently for the practice and practice is used separately so that there is a difference in shaft strength of each club practiced power swing It was difficult to apply this practice, and it also had a problem that the sense of practice caused by the practice was deteriorated, which is why the club's exact impact on the ball was not achieved in practice, which is contrary to the intrinsic purpose of increasing the distance by power swing. .

Therefore, the present invention has been made to solve the problems according to the prior art as described above,

It is an object of the present invention to have a predetermined weight of rubber material as a golfer's shaft in the golf club used in practice, one side is cut to open and close the practice ball that is closed by the connecting ring to the shaft to actually use the golf It is easy to apply the practice according to the power swing practice by enabling the swing practice through the club, to increase the distance according to this, and to provide the practice ball for detachable shaft that can make the swing rhythm according to the weight of the practice ball. have.

Specific means for achieving the above object;

As a spherical hard rubber, the outer circumferential surface of the sphere is made in the longitudinal direction through the center of the sphere to the other end, and one side is connected to each other, and the formed incision surface forms an inclined incision that forms the incision angle of the external optical narrowing. Perforating the installation hole in the direction of the central axis, the inner circumferential surface of the sphere in which the installation hole is formed is formed by the installation surface of the silicon material, and the outer circumferential surface of the incision sphere is achieved by providing a practice ball for detaching, attaching the shaft with a pair of connecting rings.

When described in detail on the basis of the accompanying drawings, the exercise ball for detaching, attaching the shaft according to the present invention having the configuration as described above are as follows.

1 is a perspective view of the practice ball for detaching, attaching the shaft of the present invention, Figure 2 is a cross-sectional view showing a cross-sectional view of the exercise ball for detaching, attaching the shaft of the present invention, Figure 3 is a perspective view showing a state of use in accordance with the present invention to be.

As shown therein, the practice ball for detaching and attaching the shaft of the present invention is a spherical hard rubber having a certain weight, which forms an incision up to the other end via the center of the sphere in the longitudinal direction of the outer circumferential surface of the sphere, but has one side connected thereto (10). The incision surface formed by the incision forms an inclined incision portion 12 forming an incision angle of the outer light inner circumference, punctures the installation hole 14 in the direction of the central axis of the sphere, and the inner circumferential surface of the sphere on which the installation hole 14 is formed. The mounting surface 16 is made of silicon.

In addition, it has a characteristic configuration that the pair of connecting ring 20 is attached to the outer peripheral surface of the sphere is cut.

Therefore, looking at the operation and effect of the shaft removal, attachment exercise ball having the configuration as described above are as follows.

As shown in FIG. 3, the practice ball of the present invention is used by binding to the head engaging portion of the shaft 301 of the golf club 30 for practical use.

At this time, the practice ball is inclined incision 12 as described above is formed to be inclined in the form of external light narrowing in the shaft insertion direction of the golf club so that the shaft can be guided smoothly along the incision surface when inserting the shaft In addition, as one side is connected to the shaft (301) from the outer diameter by forming the connection portion 10 is connected to the practice ball of the present invention is pushed to the left and right both sides through the connection portion 10 and the installation hole formed in the practice ball ( 14) after the shaft is inserted into the complete shaft can be returned to its original position by the elasticity of the connecting portion 10 as shown in FIG.

Therefore, as described above, the outer detachment of the practice ball may occur due to the centrifugal force acting upon the swing only by the elasticity of the connection part 10 of the practice ball in the state where the shaft of the golf club is inserted into the incision of the exercise ball as described above. By forming a pair of connecting rings 20 on the outer circumferential surface of (12), it would be desirable to prevent the external deviation of the practice ball during practice power swing in a state where the practice ball of the present invention is attached to the shaft.

On the other hand, by forming the material of the above-described mounting surface 16 of a high viscosity auxiliary material such as silicon to prevent the phenomenon that the practice ball is transported up and down along the shaft 301 while the practice ball is installed on the shaft 301. It can be fixed at the position installed on the shaft.

Therefore, in the swing practice as described above, while practicing the power swing through a heavy golf club with a practice ball installed in practice, the golf club is actually used because the light golf club is used as a state in which the practice ball is dismantled. You can expect a more powerful swing than when you practice.

As described above, the present invention can be applied to all the clubs used by the user in practice to improve the practical stress on the golf club, and after practicing the swing with the practice ball installed with a heavy weight, the practice ball in practice. Since the game proceeds in the dismantled state, the golf club used by him can get a light feeling, making the power swing to increase the distance, and can be attached and detached.
