The first striking member 3 is composed of a high step a on the inner peripheral side of the fore edge and a low step b on the outer peripheral side. It is also formed on the second striking member 4 and the third striking member 5 respectively. The material of the high step a can be wood, resin, elastic member, or the like. In addition, by changing the material of each high step a of each striking member, it is possible to produce a different impact sound at each impacting position of each impacting member, and there is also a method in which the form can be confirmed by the sound. Conceivable.
Also, the role of the high step a is to suppress impact force and air resistance. Furthermore, the pressure at the time of collision can be increased, and the push at impact can be strengthened during swing practice.

It is composed of a high step a, a high step a' on the inner peripheral side of the fore edge of the second striking member 4, and a high step a'' on the inner peripheral side of the fore edge of the third striking member 5.
At the beginning of the swing, the first striking member 3 is the lightest of the three striking members and the longest distance from the grip portion 7, so that the centrifugal force is likely to act, and the first striking member 3 is easily ejected in the direction in which the centrifugal force acts. It is structured to move to the striking member 2 side.

FIG. 11 shows the position of the striking member at the time of impact of the practice tool 1 for increasing the flight distance of the present invention. Impacting member 2, first impacting member 3, second impacting member 4, third impacting member 5, lower portion 5' of third impacting member, shaft 6, grip portion 7, high step on the inner peripheral side of the fore edge of the first impacting member a, a high step a' on the inner peripheral side of the fore edge of the second striking member, and a high step a'' on the inner peripheral side of the fore edge of the third striking member.
As described above, since the first striking member 3 is the lightest and is the longest distance from the gripping portion 7, centrifugal force is likely to act, and among the three striking members, the first striking member 3 begins to move toward the struck member 2 side, Collide with member 2. After that, the second striking member 4 on which the centrifugal force acts second most begins to move and collide with the first striking member 3 .
Since the second striking member 4 is heavier than the first striking member 3, when the centrifugal force begins to act, the speed of the second striking member 4 increases, and the force that collides with the first striking member 3 and pushes it in the hitting direction from the impact. comes to work.

FIG. 12 shows the positions of the respective striking members at the time of the final push when the third striking member 5 collides with the second striking member 4 during the practice swing of the practice tool 1 for increasing flight distance of the present invention. The member to be struck 2, the first striking member 3, the second striking member 4, the third striking member 5, the lower portion 5' of the third striking member, the shaft 6, the grip portion 7, and the inner peripheral side of the fore edge of the first striking member are high. It consists of a step a, a high step a' on the inner peripheral side of the fore edge of the second striking member, and a high step a'' on the inner peripheral side of the fore edge of the third striking member.
For example, if the striking members 3, 4, and 5 shown in FIG. 12 are not separated and are integral striking members, they will collide with the member to be struck 2 with a considerable impact due to their increased weight and length. . When the force of collision becomes strong, force is applied to the arms and shoulders, making it impossible to lightly grip the gripping portion 7. - 特許庁In addition, the muscles in the upper body of the arms and shoulders become stiff and the lower body loses flexibility, making it impossible to perform a powerful swing with the weight on the pivot leg.
Therefore, by dividing the striking member into three parts, it is possible to disperse the force of the impact, and by reducing the load, it is possible to make a light grip without straining the arms and shoulders. Because the grip is light, the follow-through naturally increases, and since the arms and shoulders are not strained, it becomes possible to put the weight on the pivot leg and practice swinging in the direction of hitting the ball.
By practicing pushing, it is possible to extend the flight distance and hit the ball with greater force and speed.

Furthermore, by narrowing the fore edge of each striking member on the tip side and forming gaps a, a' and a'' between the striking members, the air resistance is small and the swing is smooth when the swing is performed. With less air resistance, you can feel less strain on your hands and arms, and you can finish with a light grip until the last follow-through.

FIG. 13 shows the position and trajectory of the striking member from the impact to the pressing during the practice swing of the practice tool 1 for increasing the flight distance of the present invention. Hit member 2, first hitting member 3, second hitting member 4, third hitting member 5, gripping portion 7, first impact point (1), second impact point (2), third impact point (3) consists of trajectory A at the beginning of the swing, trajectories B and B' from the time of impact until pushing, and trajectory C of the follow-through.
(1) is the first impact point where the first hitting member 3 collides with the hit member 2 . The first hitting member 3, which is the lightest in weight among the three weights, is likely to exert centrifugal force and collides with the member to be hit 2 to produce the first impact sound. From this impact point (1), the body begins to prepare to put weight on the pivot foot.
(2) is the second impact point at which the second striking member 4 collides with the first striking member 3 . A second beating sound is heard here. By forming the second striking member 4 to be heavier than the first striking member 3, when the centrifugal force begins to act, the speed of the second striking member 4 increases and it collides with the first striking member 3 to apply pressure to the first striking member 3. play a pushing role. By pushing the first striking member 3, the arm gripping the grip part 7 extends forward, and the arm pushes forward while applying weight to the pivot leg at the second impact point (2).
In (3), the third striking member 5, which is the heaviest among the three striking members, collides with the second striking member 4, and a third collision sound is produced. This is the third impact point (3). Start preparing to put the center of gravity on the pivot foot from trajectory B, and push forward while stretching your arms with your lower body to B', creating a long trajectory on the BB' line. The impact point is not a point, but a long line like BB', so even if the batter is broken by a changeup, etc., by practicing pushing in the BB' distance, you can develop a form that leads to a hit. can be made.

In addition, the shorter the time difference between the three collision sounds, the more proof that the head speed is improving. Effective.

FIG. 14 is a comparison of the trajectory of the practice tool 1 for extending the flight distance of the present invention and the trajectories of Patent Documents 1 and 2. FIG. A swing start A, a first impact point B, a third impact point B', a trajectory F, and a follow-through C of the practice tool 1 for increasing the flight distance of the present invention. Swing start A, trajectory D, follow-through C″ in Patent Document 1, and swing start A, trajectory E, and follow-through C′ in Patent Document 2. All of them are comparisons made by our company, but the number of striking members is one. 1 is a training device that concentrates on the impact, so the force is applied to the arms and shoulders due to the impact, and the follow-through C″ does not stretch as much as expected. Further, in Patent Document 2, since there are two striking members, the pushing force is stronger than that in Patent Document 1, but since the edge of the striking member is flat, the effect of dispersing the impact force is low, and the arm The impact zone is smaller than the trajectory F of the practice tool 1 of the present invention that increases the flight distance by applying force to the shoulders and shoulders, and the forward pushing becomes weaker.
The trajectory F of the practice tool 1 for increasing the flight distance of the present invention has a longer impact point BB' and a larger follow-through C than those of Patent Documents 1 and 2.

FIG. 15 shows the respective distances between the grip portion 7 and the three hitting members of the practice tool 1 for increasing the flight distance of the present invention. Hit member 2, first hitting member 3, second hitting member 4, third hitting member 5, gripper 7, position (10) of hitting member when held, first impact point (1), second The impact point (2), the third impact point (3), the distance 3r between the center gripping portion 7 and the first striking member 3, the distance 4r between the center gripping portion 7 and the second striking member 4, the center The distance 5r between the gripping portion 7 and the third striking member 5, the distance 3r′ between the central gripping portion 7 and the first striking member 3 at the position (10) of the striking member when the gripping portion 7 is held, and the distance 3r′ from the gripping portion 7 to the second striking member It is composed of a distance 4r' to the striking member and a distance 5r' from the grip portion 7 to the third striking member.

Since the centrifugal force increases as the radius of rotation increases, the first striking member 3 is located at the longest distances 3r and 3r' from the central gripping portion 7, and moves quickly toward the struck member 2 side. It has become. Next to move is the second striking member 4, the distance from the grip 7 being 4r, 4r'. The third striking member 5 that moves last has the shortest distances of 5r and 5r' from the grip. The third striking member 5, which is assumed to have the weakest centrifugal force, is designed to have the heaviest weight among the three striking members and to have a shape with a smaller diameter at the lower portion 5' for smooth movement. As the movement becomes smoother, the centrifugal force acts more easily, and the load when colliding with the second striking member 4 increases. This makes it possible to master a strong push that greatly expands the impact zone.

The greatest feature of the practice tool 1 for increasing flight distance according to the present invention is the structure in which the impact force (ie, the load) with which the striking member collides with the member to be struck can be reduced by using three striking members. By reducing the weight and releasing the force from your arms, you can perform an epoch-making exercise that strengthens the pushing forward.
In addition, the strength of the centrifugal force can be determined by the distance from the grip portion 7 to each striking member, and furthermore, the weight and shape, and a time difference can be created in the movement of each striking member. By creating a time difference, the second hitting member and the third hitting member can each apply force forward, and useful practice of pushing deeply in the hitting direction during practice swing can be performed.
In addition, by making a practice swing with the side of the member to be hit upright (so-called form with the head left), it is possible to make a powerful practice swing with the weight of the lower body on the body, and after the third impact, it is naturally pulled outward and has a strong follow. You can master the technique of extending the flight distance through.

Furthermore, it is also possible to change the length, weight and shape of each striking member and change the position. Thereby, the balance of the center of gravity at the time of impact can be changed at will. For example, a head balance that puts the center of gravity on the head side is for long-distance hitters, a middle balance that puts the center of gravity in the middle is for medium-range hitters, and a hand balance that puts the center of gravity on the hand side. manufacturing becomes possible. These are methods such as making the first striking member 3 at the longest distance from the gripping portion 7 the heaviest, making the second striking member 4 at an intermediate distance from the gripping portion the heaviest, etc. There are a wide variety of combinations, such as making the two striking members 4 of the same weight.

By improving batting techniques for baseball and golf, we will raise the level of the sports population involved in each and increase interest in sports.
