[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a swing training tool for ball games such as baseball, golf, and tennis (hereinafter abbreviated as “training tool” as appropriate).

[0002]

[Prior art]

 Conventionally, as a practice tool and method for the ball game, a dedicated practice tool is mainly used, the practice result is replaced with an image of actual sports equipment, an actual sport equipment is used, and it is installed in a separate place. There are various methods such as detecting limited elements with a training device and transmitting the results to the player himself.

[0003]

[Problems to be solved by the device]

 In the former case, there is a difference in weight, shape, center of gravity, balance, feel, etc. between the dedicated training equipment and the actual sports equipment, so that the practice result and the actual sports equipment are likely to deviate from each other, and In the latter case, it is necessary to secure sufficient space for practice and to use the installation technology for the training equipment to function properly, and it is necessary to check and manage to maintain the function, and However, it is economically difficult to keep and use the space and training device as a single person, and thus it is not common.

The present invention has been made in view of the above problems of the conventional technique, and an object of the present invention is that the head speed of the training tool is the maximum during the swing process during practice. It makes it possible to significantly shorten the time required for the player to check, judge, and correct, and to make it easier to master swing technology, and to practice easily without taking up any space. Moreover, it is to provide swing exercise equipment for ball games such as baseball, golf, and tennis, which are inexpensive.

[0005]

In order to achieve the above object, a swing training device for ball games such as baseball, golf, and tennis according to the present invention has one end on the grip side of a sports device and the other one. The non-magnetic moving member is housed in the middle part of the non-magnetic cylindrical main body whose end sides correspond to the head side of the sports equipment, and is reciprocally movable in the axial direction of the cylindrical main body. In the grip body and the head side of the tubular body, a holding piece of a non-magnetic material having a magnet arranged on the moving member side and a collision piece of the non-magnetic material are provided, respectively, and the tubular body In the above, a through hole is provided in a portion between the holding piece and the collision piece.

In such a practice tool, between the inner diameter of the cylindrical body and the moving member, the moving member allows air to flow between the magnet and the collision piece through the through hole. It is preferable to secure a gap necessary for smooth movement.

Further, the magnets arranged on the holding pieces are permanent magnets, and a plurality of holding pieces having fixed magnetic flux densities are prepared, and the holding pieces are appropriately made according to the level of the player and the difference in sports equipment. Further, it is preferable that the tubular body can be easily replaced so that the tubular body can be reassembled.

For the same purpose, it is preferable to change the shape of the moving member so that different weights can be selected.

Further, the contact surface between the magnet and the moving member has a flat surface for the magnet and a spherical surface for the moving member to reduce the contact area, and when the moving member is attracted to the magnet, It is preferable that no matter where the magnets come into contact with the magnet, they exist in the same magnetic flux. It is also preferable that no element other than the magnetic flux is present.

[0010]

[Action]

 The training equipment constructed as described above should be adjusted so that its grip side and head side are aligned with the grip side and head side of the sports equipment, and that the training equipment has a point position specific to the sports equipment or a position along the training purpose. Put it on the sports equipment and use it with both fixed.

When the swing movement of the sports equipment is performed in this state, for example, when a series of movement starts from the state where the moving member is located on the head side, the head side of the training equipment is up and the grip side is down at the backswing stage. Therefore, the moving member falls under its own weight, collides with the magnet and is attracted to the magnet, and the light collision sound generated at that time allows the moving member to move to the grip side by hearing. . In addition, it is possible to visually confirm that the moving member has moved by looking through the through hole.

When moving to the downswing stage, the moving member receives the centrifugal force generated by the rotational movement, but at this stage the head speed does not reach the maximum, so the attractive force of the magnet exceeds the centrifugal force, The moving member maintains the adsorbed state. Next, when the stage of impact is reached, the centrifugal force received by the moving member exceeds the attraction force of the magnet, and the moving member moves away from the magnet against the attraction force of the magnet and accelerates to move to the head side to collide with the collision piece. And collide with and generate a collision sound. At the same time, at this time, the flow of the air generated by the movement of the moving member in this way is smoothly performed without applying pressure or negative pressure to the inside of the cylindrical body by the through hole.

Then, in the follow-through stage, when the centrifugal force and inertia received by the moving member disappears and the moving member's own weight acts, the moving member moves to the magnet side again and is attracted to the magnet at the same time. The moving member does not move while being attracted to the magnet until a backswing condition that starts with the head side up and the grip side down again is satisfied.

As described above, the adsorption sound or the collision sound generated when the moving member is attracted to the magnet or collides with the collision piece is clearly heard and confirmed from the through hole to the outside.

【Example】

 An embodiment will be described with reference to the drawings. A cylindrical main body 2 which constitutes a training tool 1 of the present invention is made of a non-magnetic material such as aluminum, and has an outer diameter of 12 mm, an inner diameter of 10 mm, and a length. A cylindrical pipe of about 70 mm is used. The tubular body 2 has an end 2G on one side (left side in the figure) corresponding to the grip side of the sports equipment, and an end 2H on the other side (right side in the figure) of the sports equipment. It corresponds to the head side. Through holes 2A and 2B of male screws, which will be described later, are formed on the upper side and the lower side of the grip-side and head-side ends 2G and 2H of the cylindrical main body 2, respectively. The through holes 2A and 2B are provided so that the thread diameter and the root diameter of the threaded portion of the male screw pass therethrough. Further, a substantially triangular through hole 2D is formed in the middle portion 2C of the cylindrical main body 2, that is, on both side surfaces of the portion between the holding piece and the collision piece, which will be described later, near the holding piece. Drill so that it faces you.

A ball 3 as a moving member is accommodated in the cylindrical main body 2 so as to be reciprocally movable in the axial direction. The ball 3 is made by processing non-magnetic iron into a horizontal capsule shape, and each end 3A in the axial direction has a semi-curved curved surface. The outer diameter is about 8 mm, and the length is 10 mm ~. It is 20 mm. The balls 3 can be variously manufactured by exchanging different weights mainly by changing the length.

The holding piece 4 is fixed in the grip side end portion 2G of the tubular body 2. That is, the holding piece 4 is formed by processing a cylindrical rod rod of a non-magnetic material such as aluminum, and has dimensions of an outer diameter of 10 mm and a length of about 18 mm. A female screw 4A having a diameter of 4 mm is provided in a substantially middle portion in a direction perpendicular to the axial direction (vertical direction in the figure). The holding portion 4 is fixed to the tubular body 2 by screwing the female screw 4A into the threaded portion 5A of the male screw 5 which penetrates the through hole 2A of the tubular body 2.

As the male screw 5, a non-magnetic material such as stainless steel having a driver groove 5C in the head portion 5B and having a diameter of 4 mm and a total length of about 17 mm is used. The length of each part is 6 mm for the base part 5D, 9 mm for the screw part 5A, and 2 mm for the root diameter of only the tip part 5F. The head portion 5B and the base portion 5D form a locking portion 7 for engaging with sports equipment. The tip portion 5F of the male screw 5 functions as a guide when the holding piece 4 is assembled and fixed to the tubular body 2.

Further, a recess 4B having a diameter of 5.1 mm and a depth of about 2 to 5 mm is formed in the central portion of the holding piece 4 on the side facing the ball 3, and the magnet 8 is attached to the recess 4B with an adhesive. Embed and fix.

The magnet 8 is a permanent magnet having an accurately displayed magnetic flux density, an outer diameter of 5 mm, and a length of about 2 to 5 mm, and a magnet whose length change has the same relationship as that of the magnetic flux density is selected. To do. The end surface 8A of the magnet 8 on the ball 3 side is a flat surface so that the contact area with the side end portion 3A of the pole 3 is reduced.

In the head-side end portion 2H of the tubular body 2, a collision piece 9 having an outer diameter of 10 mm and a length of 12 mm, which is formed by processing a cylindrical lot rod of a non-magnetic material such as aluminum, is formed. Set up. Similar to the holding piece 4, a female screw 9A having a diameter of 4 mm is vertically provided approximately in the middle of the collision piece 9 in the longitudinal direction, and a male screw 5 having the same specifications as the male screw 5 is screwed into the female screw 9A. Then, the collision piece 9 is fixed to the tubular body 2. The head portion 5B and the base portion 5D of the male screw 5 used on the side of the collision piece 9 serve as a locking portion 7 for the sports equipment, and the tip portion 5F serves as a guide for assembling and fixing the collision piece 9 to the tubular body 2. The same applies to the male screw 5 on the holding piece 4 side.

The total weight of the training implement 1 assembled in this manner is about 20 g.

The usage method and operation of the training tool 1 are as follows. For example, in the practice of hitting a ball in baseball, the first step is to select a training tool that matches the player's own level. That is, looking at the triangular vertex 2E of the through hole 2D of the practice tool 1, aligning the direction of the practice tool 1 with the direction of holding the bat, sandwiching the head side with the thumb and forefinger, and holding the grip side with the palm. Grip lightly to perform a throwing motion, and select a practice tool that makes a collision sound between the ball 3 and the collision piece 9 at the time of maximum snap.

Next, as a second step, as shown in FIG. 3, the direction of the practice tool 1 is aligned with the grip side and the head side direction of the bat 11 using the direction of the apex 2E of the triangle of the through hole 2D. Then, the practice tool 1 is superposed on the periphery of the shin 11A of the bat 11, and then one end of the connecting cord body, for example, the rubber band 12 is hooked on the locking portion 7 to maintain proper tension while maintaining the proper tension. After the training tool 1 and the bat 11 are wrapped around the butt 11 and the bat 11 so as not to be loosened, the training tool 1 is fixed to the bat 11 by hooking the other end of the rubber band 12 to the locking portion 7. .

Then, as a third stage, the player makes a swing at the head speed determined by the player himself, and at the impact point, the sound of collision between the ball 3 and the collision piece 9 is heard, and the practice tool 1 is matched. To confirm. If the collision noise is generated during the downswing, replace it with another holding piece to which a magnet having a larger magnetic flux is fixed, or another ball having a lighter weight. If the collision noise does not occur even after passing the impact point, replace it with another holding piece with a magnet with a smaller magnetic flux fixed to it, or another ball with a heavier weight to repeat the swing. Select a training tool that matches.

After selecting the most suitable training implement 1 in this way, the practice motion is started, and when the player swings at the best head speed, the ball 3 in the tubular body 2 collides at the impact point. Since a collision sound is emitted upon collision with the piece 9, it is possible to judge whether or not the player himself can maintain the best head speed at all times and repeat the motion without slowing down.

If the impact sound at the impact point cannot be heard when the bat 11 is replaced, the grip position or the form is repeatedly changed until it can be heard. , It is possible to judge whether the bat 11 is suitable for the player himself.

In addition, by performing a swing while assuming the type and course of the pitched ball, it is possible to confirm the change of the impact point, reach out the player's advantage, and easily perform the narrowed-down practice for the weak point. Become.

Furthermore, by comparing the magnetic flux value of the magnet and the weight of the ball of the practice tool used by the higher-ranked player with the goal of the practice tool, the player can be encouraged and practiced as a familiar goal for leveling up. can do.

The training equipment and the sports equipment are other than baseball, for example, in the case of golf, around the portion from the shaft to the face through the hosel, and in the case of tennis, between the grip and the frame. It should be fixed around the parts close to the frame, such as at the points specific to each sports equipment, or at a position that suits the purpose of training.
