Description

Golf swing posture correction device

The present invention relates to a golf swing posture corrector, and more particularly, to an apparatus for correcting posture in the backswing and downswing processes.

In sports such as golf, in which the ball is hit with a stick, the swing posture is important. If you want to reach a certain level or higher, you have to learn a certain shape of the swing form through repeated practice.

However, golf is an extreme upper swing that hits a ball on the ground, and it is difficult to learn an accurate swing posture because the swing trajectory is different from other sports. Therefore, beginners spend a lot of time in the practice field to learn the correct swing posture before going out to the field.

The golf swing consists of a backswing to prepare for a swing, a downswing to hit the ball, and a follow-up swing after hitting. In order to learn a certain swing posture, the posture at the moment of transition from the backswing to the downswing is accurate and constant. should be kept That is, at the end of the backswing, that is, at the moment of transition to the downswing, the distance between the golf club and the body, for example, the shoulder, must be kept constant. In addition, in the downswing process, it is important to maintain the posture so that the arm does not rotate first so that the arm is attached to the body and rotates together to make the downswing.

Accordingly, in order for beginners to learn this in the process of swing practice, the coach examines and corrects the process of converting from the backswing to the downswing and the posture of the downswing, which takes a lot of time and money. Another method is to record your swing process with a camera and monitor it to correct your posture, which is also a process that requires complex equipment and time.

In order to overcome this problem, devices for correcting the posture of the golf swing have been developed. Republic of Korea Patent No. 10-13253060000, 'golf swing posture corrector' discloses a device for correcting posture while worn on the body.
