Description

    The present invention relates to a practice golf club and a golf practice apparatus.

    A golf club has a club head attached to the tip of a shaft, but its sweet spot is offset from the central axis of the shaft. It is difficult to just meet a ball with such a golf club. The reason is that the sweet spot of the club head is away from the center line of the shaft. That is, as shown in FIG. 1, since the club head is offset with respect to the shaft, the hitting point is not on the extension line of the shaft.

    As a human sense, it is natural that there is a dot on the extension line at hand. That is, as shown in FIG. 2, the normal chopsticks have a straight line from the hand for grasping the object, so that no trouble is required when grasping the object. However, in the case of the chopsticks as shown in FIG. 3, since the hand and the tip for actually grasping the object are not in a straight line, training and familiarity are required to grasp the object well. Next, if there is a chopstick as shown in Fig. 4, this chopstick has a complicated shape, but the hand and the tip that holds the object do not deviate from the straight line. The object can be easily grasped.

    In other words, if the hand and the point that is in direct contact with the object are in a straight line, the operation is considered easy.

    Therefore, in golf, since there is a club face that becomes a hit point with a shift from the position of the shaft, the tip of the shaft on the extension line of the hand passes in front of the ball so that the ball can be hit correctly. Here, when the ball is the actual target, it is difficult to play golf because it is necessary to swing before the target deviates.

    Furthermore, the center of gravity of the golf club is also offset from the center axis of the shaft. It is also difficult in golf to control this center of gravity during a swing.

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

    In other words, if the offset can be made zero on the image and the center of gravity can be controlled, the ball can be met relatively easily.

    That is, the gist of the present invention is to transmit information from the eyes to the brain as if the vicinity of the center of gravity from the hand holding the club and the sweet spot is on a straight line as an extension, and to improve the controllability of the center of gravity. To do. In other words, it provides a practice golf club and a practice instrument that can be worn with an efficient swing by planting a sense and consciousness that the hitting point and the center of gravity are on the extension line of the hand shaft, and improving the controllability of the center of gravity. For the purpose.

    In order to achieve the above object, a virtual shaft of a predetermined length is mounted along the shaft of the golf club, and one end of the virtual shaft points at hand and the other points near the center of gravity from the sweet spot of the club head. A golf club is provided.

    The virtual shaft can be arbitrarily adjusted and removed with respect to the shaft of the golf club. Further, a visual appealing mark is provided at the tip of the virtual shaft, and the mark is made 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. Further, some of the virtual shafts can be expanded and contracted, the length thereof can be adjusted, the club head side end portion of the virtual shaft can be retracted from the club head, and a ball can be actually hit with the club head.

    The types of the virtual shaft include metal pipes, plastic pipes, carbon pipes, extendable pipes, springs, rubber strings, string strings, ropes, laser beams, light beams, etc., all of which have the same effect.

    There is also provided an exercise device comprising a virtual shaft and an attachment to the club, which is mounted on a normal golf club and has the same function as the golf club and produces the same effect.

    That is, it has a mounting tool to the shaft of the golf club, and by this mounting tool, it consists of a virtual shaft that can be attached to and detached from the shaft of the golf club. The other end of the exercise tool is characterized by pointing near the center of gravity from the sweet spot of the club head.

    Also, for prior practice, there is also provided a practice shaft in which two shafts with grips are connected to each other at the tip opposite to the grip, and as a result, both ends are golf grips.

    Here, weights are attached to at least one grip so that the weights are different at both ends, so that you can practice with different balances when you grip one grip and the other. It is good to.

    There is also a practice shaft that is provided with a visually appealing mark at the tip, and that the mark is made of at least one of a light emitter, a reflective tape, and a fluorescent paint application body, and the swing path can be visually recognized by the mark.

    In addition, a virtual shaft of a predetermined length is mounted along the shaft of a golf club without a club head, and both ends of the virtual shaft are from the sweet spot of the club head where one is at hand and the other is originally attached. A training shaft with a virtual shaft pointing near the center of gravity is also provided. An interference tool such as rubber for absorbing an impact is provided at the tip of the virtual shaft.

    Furthermore, a visual appealing mark is provided at the tip of the virtual shaft, and the mark is made of at least one of a light emitting body, a reflective tape, and a fluorescent paint application body, and a swing path can be visually recognized by the mark.

    In addition, there is a weight that can be removed in the vicinity of the virtual shaft and the front end of the golf club or near the hand, and the weight can be practiced by arbitrarily adjusting the weight by arbitrarily adjusting the weight. In particular, the golf club shaft that is extremely heavier than the tip side can learn an ideal swing that is not affected by the weight or inertia of the tip side.

    Furthermore, there is a case where a weight is intentionally offset from the central axis of the virtual shaft in the vicinity of the tip of the virtual shaft. Thus, the weight balance is the same as that of a normal golf club, and the controllability of the center of gravity, which is the biggest problem of the golf swing generated from the offset between the shaft center axis and the center of gravity of the golf club, can be cultivated.

    In some golf clubs without a club head, the club head is attached to the tip of the shaft of the golf club in an offset state to actually hit the ball. That is, the center-of-gravity distance becomes longer than that of a normal golf club from the center axis of the shaft of the golf club without the club head, and the center of gravity can be effectively controlled.

    Also, to ensure that the center of gravity is always visible when swinging, it is equipped with a rod of several centimeters and is mounted near the tip of the golf club shaft so that it is perpendicular to the shaft, and the tip points to the center of gravity of the head. Ingredients are also provided.

    In addition, a sticker is provided that is attached so as to connect the base of the hosel and the center of gravity so that the center of gravity angle of the head of the golf club can be visually recognized.

    When practiced with the practice club, the practice instrument, or the practice shaft with virtual shaft of the present invention, it becomes as if the ball is hit on an extension line at hand, so the meet rate is significantly increased. Usually, when the ball is concentrated too much, the ball is often hit with the tip of the shaft of the golf club. It is a socket or shank in the so-called golf term. The reason is that the body reacts naturally when it strikes the ball on the extension line at hand. However, when swinging in the image of a virtual shaft, such mistakes decrease, and the more you concentrate on the ball, the higher the meet rate.

    In addition, at the time of addressing, if the club head side end of the virtual shaft is positioned on the ball about one ball ahead of the flying spot from the sweet spot, it is likely to be an ideal stance for impact. In other words, you can practice hand-first impact.

    Further, since the head is offset with respect to the shaft, the balance of the club becomes unstable during the swing, and the swing may be disturbed. However, the mounting of the virtual shaft improves the balance of the center of gravity, and by concentrating on it, the influence of the conventional club offset brought about by vision is mitigated, and it is easy to wear a stable swing. In other words, unnecessary rolling of the club is suppressed, and the entire swing is stabilized from the down swing to the follow, starting with the take back.

    Further, the practice shaft with a virtual shaft does not have a club head, so that it is released from an unstable balance and can easily wear a correct swing as compared with the case with a head. In particular, those equipped with weights on the hand side are less susceptible to the inertia of the front end side during swing, and are more effective.

    Furthermore, if the weight is attached with an offset in the vicinity of the tip of the virtual shaft, the controllability of the center of gravity can be further improved. In other words, you can feel the sense of having the center of gravity firmly on the shaft, so you can easily wear the ideal swing.

    Also, if you practice with a golf club that does not have a club head attached to the tip of the shaft of the golf club that is offset and can actually hit the ball, the center of gravity distance is longer than that of a normal golf club. This makes it easier to experience various phenomena. Therefore, the club can be effectively controlled, that is, the center of gravity can be controlled.

    In addition, it becomes easier to control the center of gravity by using a practice tool that can always see the position of the center of gravity when swinging. Ideally, the center of gravity should be directly above the shaft when the club is parallel to the ground during takeback and downswing in a golf swing. Swing can be easily checked with the practice tool.

    FIG. 5 shows a first embodiment of the present invention. As shown in FIG. 5, the virtual shaft is attached to the golf club. One of the virtual shafts is near the center of gravity from the sweet spot, and the other is the hand holding the club. In addition, as shown in FIG. 6, when the virtual shaft is set so that the club head side end of the virtual shaft comes about one ball forward from the sweet spot, the hand-first position It becomes.

    Next, as shown in FIG. 7, mark a ball size on a practice mat or the like instead of the ball, and think that it is a ball and swing. In this case, it is important that the club head side end portion of the virtual shaft is passed over the mark that looks like the ball. This is practice.

    This practice is continued until the end of the virtual shaft on the club head side end can be passed over the mark that is likened to the ball, and then the ball is actually hit with a normal golf club. Then you can just meet the ball more accurately and easily than before.

    Further, by adjusting the length of the virtual shaft, it is possible to hit the ball with the virtual shaft mounted.

    Before starting this practice, it is more effective if the golf club is like a shaft without a head and can be swung on the mark on the practice mat. This is because even golfers are not accustomed to hitting the ball accurately with the tip of the shaft. In this case, a rubber tee may be targeted instead of the mark on the practice mat.

    For this prior practice, a predetermined length is provided along the practice shaft having both ends as golf grips as shown in FIG. 8, and the shaft of a golf club without a club head as shown in FIG. There is also provided a practice shaft with a virtual shaft to which the virtual shaft is attached. It is an ideal practice tool in terms of balance and weight.
