Golf swing exercise device {DEVICE FOR EXERCISING SWING GOLF}

The present invention relates to a golf swing practice apparatus, and more particularly, to a golf swing practice apparatus that can practice while checking the swing posture, swing speed, flight direction, flying distance with golf clubs and mats during golf swing practice .

Golf is a sports club that consists of various types of clubs such as wood, iron, and putter. It is a sport in which the ball is put into the hole cup with the smallest number of strokes while randomly setting the course and the number of strokes.

Therefore, the golfer needs to have the correct basic posture and swing posture in order to put the ball in fewer strokes than the number of shots in the green hole cup. In other words, if the correct basic posture and swing posture are not good, the ball will not be hit accurately, so it will not only fly in the direction of the desired batting, but the distance will also be shortened so that the ball cannot be put into the hole cup with the desired stroke. Due to inconvenience to colleagues as well as rounding time is accompanied by a variety of problems.

Therefore, the golfer must go to the field with the correct basic posture and the correct swing posture before the rounding of the field. That is, the golfer needs a lot of practice to learn the correct posture. Using the exerciser, golf simulation, golf swing guide, golf swing correction device, putting exerciser, you will practice basic posture, swing posture, and putting posture.

Among them, even beginners and professional golfers will practice the correct swing posture for even better skills, and the correct swing posture is the position of the club head, the accuracy of the angle, the head's heading direction, speed and flexibility. It is important to keep the ball in the correct and stable position so that the ball can move exactly in the direction and distance you want when shooting.

Therefore, when practicing swing posture, it is common to use the mirror to visually check the swing posture and correct it. Therefore, it is very difficult to check the angle, position and swing speed, tempo, etc. of the club head through the naked eye swing action is a problem that can not determine whether the posture is wrong.

Therefore, recently, for more efficient swing practice, a sensor is installed at a predetermined distance on the golf bench, and the swing speed and head angle are calculated by the time difference detected by the sensor, and displayed by using a separate display device. In addition, a swing analyzer using an infrared sensor analyzes the speed of the swing club, the tempo, the path of the club head, the angle of collision between the club head and the ball, the distance of the ball and the expected path, and displays them on a separate display unit. I have something to do.

However, the swing exerciser practicing using the sensors is displayed after the swing to analyze and confirm the swing posture, so that the postures taken during the swing cannot be easily remembered, and thus, there is a lack of accurate posture analysis and correction.

In addition, not only golf but also sports using bets and sticks (baseball, hockey, etc.) should not be headed up at the moment of swinging (impact) at the moment of the correct hit is made, so that it can proceed in the correct direction and distance In view of this, the swing exercisers may help a little to analyze and correct the overall swing posture during the swing, but the swing posture may be corrected without hitting the head up at the moment of hitting the most basic posture. There is no device that can be taken, the problem is that you can not perform accurate swing posture correction exercises.

The purpose of the present invention is to make it possible to swing while checking the angle of swing, swing trajectory, and speed with the naked eye at the time of golf swing practice, to enable accurate swing practice.
