Description

Swing practice golf club

The present invention relates to a golf club for swing practice, and more particularly, to improve the speed at which the golfer rotates the golf club, and to check the down swing and impact points at which the flying distance of the golf ball is determined. It relates to a golf club for swing practice that helps golfers correct their posture.

Golf is an athletic event in which a ball is hit with a golf club and put into a predetermined hole in a stadium equipped with a large number of holes, and the number of strokes is high and low.

The golf club is a batting rod that strikes a ball, and is generally referred to as a golf club, and includes a driver, wood, and iron depending on a head having a batting surface.

In golf, when hitting a golf ball using a golf club as described above, the flying distance and movement path (direction) of the golf ball are determined according to the swing posture and swing speed of the golfer. Accordingly, it is repeated for the correct swing posture of the golfer. In-swing practice is required.

These swings are mainly golf because it is very important to maintain the correct swing posture leading to back swing, top of swing, down swing, impact, and follow through. It is important to keep the correct swing posture at all times when practicing the swing of the club so that the correct hit is made.

For this reason, in order to maintain an accurate and constant swing motion, swing practice is continuously performed using a golf club.Unskilled golfers, if strong force is applied to the shoulder or a smooth swing is not achieved, when hitting the ball, Even before hitting the ball, the head is lifted along with the rotation of the body, so that the gaze does not coincide with the head of the golf club, and a head-up phenomenon occurs in which the gaze rises first, making it impossible to accurately hit the ball.

In particular, beginners cannot accurately grasp the rhythmic feeling of the swing and the required swing speed, so training equipment that can directly recognize this, that is, a golf club for swing practice, is in demand. Accordingly, various training golf clubs or training equipment have been developed. Has been provided.

As a prior document related to this, there is'Patent Document 1'.

The'Patent Literature 1'relates to a golf club for backswing practice with an elastic member for practicing the backswing, and the movement distance of the moving member moving in the shaft of the golf club is long, so that the user generates not only the sound of hitting but also the moving member The wrong backswing posture and speed can be easily corrected through vibration

Since the moving member and the moving path are designed to react by magnetic force, the effect of practicing is improved by feeling as if the club is sprayed during impact and follow swing, and when the moving member touches the end of the moving path, vibration is felt better by using an elastic member. The effect that can be provided is provided.

Such'Patent Document 1'describes a golfer through vibration generated when a moving member constituted in the golf club moves from the handle to the head when swinging a golf club, and sounds and vibrations generated when contacting the head. Although the swing posture can be corrected by allowing the player to directly recognize the vibration, there is a problem that the golfer can directly perceive the vibration, and the generated sound is ambiguous to determine whether the swing speed is the required speed when recognized by the golfer. When there is a part and noise occurs in the surroundings, a problem that is difficult to recognize is also generated, and therefore, training equipment capable of solving such a problem is required.
