Description

The present invention relates to a golf and baseball swing training tool, and is a swing training tool that is made of a rod-shaped body, and by repeating the swinging motion by the rod-shaped body, a correct swing can be acquired naturally and easily. It is about.

For the correct or ideal golf swing, for example:
(1) In backswing, takeback should be started without breaking the triangle formed by both arms and shoulders, and the upper body should be twisted sufficiently without moving the position of the head. (2) In the top of swing, the movement of the temporary club should be stopped to make enough slack and then turn back toward the downswing.
(3) Further, in the downswing, the head speed at the time of impact should be accelerated by delaying the return of the cock as much as possible.
(4) At the time of the impact, you should try to move your weight to create a wall on the left side of your body.
(5) Follow-through means that the head is straight out in the direction of the flying ball, and then the wrist is turned back so that the left arm is folded to draw a sufficiently large arc so that the right back is facing upward. Numerous theories have been presented, including what to do.

However, in the course of a golf swing performed in an instant, it is almost impossible to perform a swing while checking the movement according to the above many swing theories. For amateur players, being swayed by a wide variety of golf swing theories is even an obstacle to getting the right ideal swing at an early stage.

In particular, golf clubs that require a recent increase in flight distance are trying to increase the head speed by reducing the length and length of the shaft, but the distance between the player's body and the ball will be increased due to the increase in length. On the contrary, there is a problem that the meat rate of the ball is lowered, and it is required to acquire a more highly trained swing technique.
The energy transmitted to the ball at the impact of the golf swing increases in proportion to the square of the head speed and the head weight. In other words, if you swing quickly with a heavy head, the energy of the ball increases and the flight distance also increases. However, if the head weight is heavy, it will not swing quickly, and it is necessary to lighten the head weight to swing quickly. For general golfers, continuous training is the way to the correct swing that requires both head weight and head speed. It was essential.
Since three examples are shown in the following patent document as a center-of-gravity movement type training tool for guiding a golf swing to a correct swing arc, it will be described below.

Japanese Patent Publication No. 7-16538 Utility Model Registration No. 2596074 Japanese Patent No. 4210691

The training tool disclosed in Patent Document 1 has a weight pipe loaded in a short pipe simulating a grip body of a golf club, and is pressed and held by compression springs from both sides. By turning it, it is possible to experience a change in the center of gravity based on the movement of the weight due to centrifugal force, and to experience whether or not an appropriate swing is being performed.

In addition, the training tool of Patent Document 2 is configured such that an annular weight is slidably attached to a long rod-like body simulating a shaft of a golf club, and is suspended from a grip side by a rubber string (extendable elastic body). As held, by swinging the rod-like body, as described above, the swing state is self-determined by the movement of the weight due to the centrifugal force and the rubbing sound generated at that time.

The training tool of Patent Document 3 is a rod-shaped training tool that substantially corresponds to the length of the golf club in the background of the prior art as described in the above documents 1 and 2, and is simply in accordance with a golf swing. By simply swinging around, it is possible to easily experience whether or not an ideal and preferred swing is being performed. As a result, it is intended to provide a practice tool that enables a correct swing to be acquired easily and naturally. In addition, the present invention provides a golf swing practice tool that can be produced and provided at a relatively low cost without any danger during practice, and that is not likely to break down, and that is also useful for training muscles necessary for a golf swing.

In the case of a golf club, the swing weight is a fulcrum about 14 inches from the grip end, and the feeling of weight consisting of the weight of the head and the length of the club (so-called how the head works) is quantified. Therefore, it is divided into five stages from the lighter to ABCDE, and each of them is subdivided into 0 to 9 from the lighter, and is generally called “balance” or “swing balance”.
In [References 1 to 3] above, a weight that can be moved by its own weight and centrifugal force is added to the shaft, and practice is devised so that the “balance” of the shaft changes as the weight moves during the swing. This is a golf club for golfers, because the head is light when swinging down and the head becomes heavy when impacting, so both the head speed increase and the head weight increase, which are the elements for increasing the flying distance described above, are realized. We are trying to provide a practice tool that encourages training to learn the distance increase.

The swing practice tool of the present invention can be used by easily adjusting the "swing balance" suitable for the trainee's physical strength, skill and current finish level so that the training effect of the above-mentioned practice tool can be immediately enhanced. It is intended to be configured with a focus on what can be done.
In order to achieve the above-described object, the shaft of the golf club for practice of the present invention has a metal particle weight enclosed in the shaft, and the amount of metal particle enclosed depends on the physical strength, skill and current finish of the trainee. It is intended to provide a “swing balance” suitable for the level so that it can be easily adjusted.
Although the present invention has been described as a golf swing practice tool, the object of the present invention is not limited to golf, but is also used as a bat swing practice tool for baseball and softball. .

A golf swing training tool in which a metal granule is movably enclosed in a shaft extending direction from a metal tube into a baseball bat,
The shaft tube is provided with an opening through which the metal particle weight can be easily taken in and out, and the user himself can freely adjust the enclosed weight, and the opening is provided with the opening / outlet. A golf swing practice tool characterized in that a closing tool is provided to close the golf swing.

A training tool for baseball bat swing, wherein a metal granule is enclosed in a shaft tube extending from a metal tube in a baseball bat shape so as to be movable in the tube extending direction. A baseball bat swing practice tool with the same structure.

The swing practice tool of the present invention is configured so that a metal particle weight enclosed in a shaft is enclosed, and a centrifugal force applied by its own weight and swinging acts to freely move inside the shaft. Yes. That is, the metal particle weight in the shaft functions as a counterbalance (a balance weight that promotes the movement of the center of gravity), and the following “swing balance” effect is produced.
(1) The metal particle weight located on the head part side at the time of addressing temporarily moves in the direction of the grip part side by its own weight immediately before turning back from the backswing to the downswing. For this reason, the swing balance changes to the grip side, so that a counter balance state in which the head speed is increased is obtained.
(2) While moving to the downswing and reaching the impact, the head speed increases dramatically, and again returns to the head side due to the centrifugal force at which the metal particle weight is accelerated rapidly, which is a flight distance increasing element. It achieves both increased head speed and increased head weight.
The metal weight in the shaft can be easily inserted and removed from the opening of the shaft, and the amount of encapsulation can be adjusted freely, so that the user during training can counterbalance the exercise tool according to the individual physical condition and the finish level at that time Can be arranged each time. In addition, after the adjustment, the opening can be easily and surely closed by operating the closing tool, and can be used safely.

By repeating swing exercises using the practice tool of the present invention, the striking force works effectively through the process of switching from backswing to downswing, and then transitioning from impact to follow-through. The effect that such a swing can be acquired can be expected.
Use the weight of a golf club or baseball bat to “fly the ball farther” swings, ie without losing the weight of the club or bat, and without losing the reaction force and head speed at impact This is an effect that a swing can be obtained stably.

  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side cross-sectional view of the golf swing practice tool of the present embodiment in a state where the grip portion is placed diagonally upward, and FIG. 2 is a side cross-sectional view of the golf swing practice tool in a state where the grip portion is placed diagonally downward. .
It is formed in the shape of a metal bat for baseball from a hollow tube, and has a grip portion 11 that can be gripped with both hands on one side, and a head portion 12 that is thicker than the grip portion 11 formed in the shape of a hitting portion of a metal bat on the other side. . The end on the grip 11 side opens in the extending direction of the hollow tube, and is applied to the inside of the opening, so that a closing tool 15 is screwed into the screw to close the opening.

Inside the hollow tube, a metal particle weight 20 is movably enclosed, and can move in the tube with the action of gravity and centrifugal force. When the screw 15 is loosened and the closing tool 15 is removed to open the opening, the metal particle weight 20 can be sequentially taken out or increased. Note that the inner diameter of the opening is large enough to take in and out a metal granule having a predetermined size.
