Sweet spot tape for correcting hitting point of golf}

The present invention relates to a sweet spot tape for RBI correction of golf, and more particularly, it is possible to immediately recognize whether or not a hit as a touch and a sound transmitted to the fingertips during the hit, and checks his own hit group on the face after the hit. Since it is possible to accurately grasp his hitting posture, impact speed and flying distance, etc., it is related to the spot spot tape for correcting the spot of golf.

Today, golf is becoming one of the most popular sports enjoyed by many people around the world including Korea. Like most sports, golf also differs in accuracy and skill, depending on the individual's natural ability and level of effort. In particular, the golf ball is hit at the golf head face at the impact point of contact with the golf ball during the swing operation from the address to the finish, and whether or not the face at the impact point is perpendicular to the golfer's center position is the correct swing. It is a very important factor for doing this.

A typical golf club, as shown in FIG. 1, has a shaft 12 provided with a grip (not shown) that can be gripped by hand at its upper end, and a face that is joined to the lower end of the shaft 12 and is planar toward the front. The ball | bowl surface 15 consists of the head 10 in which it is formed. In addition, the connection portion between the shaft 12 and the head 10 is called a neck 11, and a portion connected from the neck 11 toward the head 10 is called a heel part 13, and the head 10 is connected to the head 10. The distal end of the c) is referred to as a toe part 14.

In the center of the face 15 corresponding to the hitting surface formed on the front side of the head 10, a virtual spot called a sweet spot 16 can be drawn, and when the ball is accurately hit near the sweet spot 16 The ball will fly ideally.

That is, according to the general golf striking principle, in order for the golfer to strike exactly in the desired direction, the face 15 of the head 10 is perpendicular to the target batting direction, and the golf ball is centered on the face 15, that is, the sweet. In the state of being kept aligned to the spot (Sweet Spot) 16, the hitting golf ball will fly in the desired direction only after hitting the ball 10 while moving to match the target hit direction after the backswing. If the hitting contact with the golf ball at the time of hitting does not coincide with the sweet spot, the hit golf ball causes a small side spin in any direction so that the trajectory of the ball is changed and the head 10 is changed. Since the hitting force of the golf ball can not be completely transmitted to the ball is reduced the distance traveled.

Such accurate hitting can be achieved only by satisfying both of the following requirements: keeping the face 15 perpendicular to the target batting direction and hitting the head 10 to match the target batting direction. Since it is not a machine, it is not always possible to maintain an accurate swing as described above, and even a skilled professional golfer always has some degree of hitting error.

That is, the average golfers often fail to achieve the correct swing due to immature or excessive tension during the swing, and this mistake is mainly an out-in swing that pulls the head 10 toward the body, or It occurs when the in-out swing is pushed outward. In the former case, the slice of the golf ball is deflected outward. In the latter case, the golf ball trajectory occurs. The hook phenomenon that is bent inwardly occurs and it is impossible to hit the desired point.

The impact motion, also referred to as reproducing the address corresponding to the ready position of the swing, is a moment when the golf ball is hit while returning to the square state at the address in the order of the face 15, the grip, the knees of the golfer, the waist, and both shoulders. In this case, the face 15 at this time must be in contact with the golf ball while maintaining a right angle at the center of the golfer to hit the golf ball at a very high speed exactly toward the target direction and fly to the maximum distance.

In addition, even if the face 15 is in contact with the golf ball while maintaining the right angle at the center of the golfer at the moment of impact, the golf ball is not in contact with the sweet spot 16, which is the center of the face 15, and the heel part 13. If the ball is biased toward the toe part 14 or biased toward the upper or lower side of the sweet spot 16, a side spin is generated in the golf ball itself by the connection operation after the impact leading to the follow-through and finish operation. As the golf ball is bent in the form of a hook or slice, the golf ball can not be hit at a desired point, and the flying distance is shortened.

Therefore, the majority of golfers spend a lot of time and effort through countless swing exercises to accurately maintain the direction of the face (15) at the moment of impact and to be able to hit the golf ball at the sweet spot 16 position of the face (15) However, until now there was no proper means to immediately check whether or not properly hit near the sweet spot (16) in the course of this practice had a great difficulty in maintaining and sustaining his own swing sense. As a result, not only could not learn a certain sense of swing in a short time, but also to spend a lot of time to overcome this was forced to practice hard.

In order to improve such a problem, recently, a technique for attaching a heat-sensitive tape to the face 15 of the head 10 to check the spot appearing on the heat-sensitive tape after swing practice has been proposed, but an effective swing In order to be able to practice and immediately grasp his propensity of hitting, it was troublesome to check it after one swing. In other words, conventional methods cannot be used to correct wrong swing postures and to conduct efficient and systematic training.

The present invention has been proposed in order to solve the above-mentioned problems, the object of which is to immediately recognize whether the hitting as a touch and the sound of the sound transmitted to the fingertips during the hit, as well as his own RBI appeared on the face after the hit By being able to check the group, it is possible to accurately grasp his striking posture, impact speed, and feeling of distance, so that the cause analysis and posture correction can be easily performed accordingly, and the golf can be maintained in practice even in practice. It is to provide sweet spot tape for RBI correction.
