Abstract

<P>PROBLEM TO BE SOLVED: To solve the following problems: the gravity center of a club head is away from the center line of a shaft, that is, the club head is attached to the shaft by offset, thereby making it difficult for a golf ball to be properly hit squarely; and the distal end of the golf club is extremely heavy, thereby making it difficult to control the club. <P>SOLUTION: In the golf practice apparatus, weights, respectively having an axial line in a direction crossing axial line of a grip, are mounted on both ends of the shaft without having the club head, and moved in a rotary direction with the axial line of the grip of the shaft without having the club head as a center. The weights are removable and adjusted in weight so as to provide practicing by changing balance. A user learns correct swing plane and wrist work by the effect of the weights, or visually recognizes the swing by mounting an LED in the distal end. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

    The present invention relates to a golf practice device.

    The golf club has an extremely heavy tip, and the center of gravity of the head is offset from the central axis of the shaft. It is difficult to swing a golf club whose tip is extremely heavy and whose center of gravity is offset from the center axis of the shaft in a well-balanced manner.

    Conventionally, there have been many practice instruments for swinging a rod-like object, but it has not been possible to acquire the technology to control the center of gravity of the club head.

In addition, there are the following documents as related prior art documents.
JP 2000-5358

    In other words, if the center of gravity of the golf club head can be controlled, the ball can be met relatively easily.

    Providing golf training equipment that can learn the operation of a golf club whose tip is extremely heavy and the center of gravity of the club head is offset from the center axis of the shaft, enhance control of the center of gravity, and wear an efficient swing The purpose is to do.

    In order to achieve the above object, there is provided a golf practice apparatus in which weights having an axis in the direction intersecting the axis of the grip are mounted near both ends of a shaft without a club head.

    And, the weight having an axis in a direction intersecting with the axis of the grip mounted near both ends of the shaft without the club head rotates around the axis of the grip of the shaft without the club head. Some of them can move in the direction you want, so you can learn the correct swing.

    Furthermore, the weight can be removed, and there are some that can be practiced by changing the balance by arbitrarily adjusting the weight of the weight.

    Further, a mark that visually appeals is provided at the tip of the shaft without the club head, and the mark is composed of at least one of a light emitting body, a reflective tape, and a fluorescent paint application body, and the swing path can be visually recognized by the mark. is there.

    When practicing with the golf practice apparatus of the present invention, the normal golf club is extremely heavy on the club head side, and the unstable balance caused by the center of gravity of the club head deviating from the center axis of the shaft is improved. And you can wear an ideal swing.

    A normal golf club has an extremely heavy tip. On the other hand, the golf practice equipment has a good balance because weights are mounted near both ends. Therefore, a natural and correct swing is acquired.

    Further, the center of gravity of the head of a normal golf club is shifted from the center axis of the shaft. Moreover, the club head is far from the gripping hand. For this reason, the balance becomes poor during the swing, and it is difficult to hit the ball correctly.

    In order to improve golf, it is important to acquire a sense of feeling the position of the center of gravity of the golf club head and the technology to control the center of gravity of the head.

    Unlike the normal golf club, the golf practice device is equipped with a weight having an axis in the direction intersecting the axis of the grip on the hand side of the shaft, so that the center of gravity of the club head is felt near the hand. Sense is easy to wear.

    In addition, the weight on the hand side and the tip can be freely rotated about the axis of the grip and the angle thereof can be adjusted, so that the club head can be opened when swinging a normal golf club. You can easily fix a player's habit of being closed, an outside-in, or an inside-out swing plane.

    Furthermore, the correct wrist work in the impact zone can be learned by the effect of the weight on the hand side and the tip.

    Furthermore, since there is a light emitter such as an LED at the tip, the swing path can be visually recognized.

    Next, FIG. 1 shows a first embodiment. As shown in FIG. 1, the golf practice apparatus is provided with detachable weights having an axis in a direction intersecting the axis of the grip at both ends of a shaft without a club head.

    As shown in FIGS. 2 and 3, the swing trajectory can be corrected by moving the weight in the direction of rotation about the grip axis by means of an adjusting bolt and an adjusting nut.

    Then, mark the ball size on a practice mat, etc., and try to swing it. In that case, it is important to swing the tip of the golf practice device so that it passes over a mark that looks like the ball. This is practice.

    Continue this practice until you are able to pass over the mark that looks like the ball, then hitting the ball with a regular golf club will make the ball more accurate and easier than ever. be able to.
