Description

Golf swing practice equipment with custom construction}

The present invention relates to a golf swing practice device, and more specifically, to a golf swing practice device that includes a user-tailored structure that can guide the swing movement and impact timing by customizing it to the user's body type and swing style during the golf swing. will be.

Golf is one of the sports that emphasizes correct posture compared to other sports, and the swing posture is the movement that requires the most correct posture.

The most appropriate swing motion is when the hands and club head rotate in a circle on a single plane during a golf swing, but this swing motion can only be learned by repeatedly practicing the correct posture.

Therefore, in order to learn the correct swing movement, you have no choice but to correct your incorrect swing movement by paying for expensive private lessons.

However, even if you are a professional golfer, if you do not practice this swing motion constantly, your posture will be disturbed and you will not be able to achieve good game results, so swing motion is an area that is emphasized not only for beginners but also for experienced golfers.

Meanwhile, general swing practice involves taking lessons at an indoor golf course or learning the swing posture on one's own, which has the problem of taking a long time to learn golf and also consuming a lot of money.

To solve this problem, golf swing practice tools of various structures have been developed, but because they use a ring track structure larger than a person's height, practice space is limited. If you want to practice a different swing posture, you can use the prepared ring track structure again. After replacing with another ring track structure, the inclination and left and right height must be adjusted again.

To solve this problem, a compact size golf swing practice tool was developed, as shown in FIG. 1.

However, these golf swing practice tools have problems in that they cannot be customized to the user's body type and swing style and cannot guide swing movement and impact timing.

Therefore, there is a need for a technology that can solve the problems caused by the prior art mentioned above.
