[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a correction bat for ball games such as baseball or softball, and more particularly, to a swing correction bat used to correct how to use a grip when swinging the bat.
[0002]
[Prior art]
Conventionally, in swing practice performed in baseball, softball, etc., practice using a swing bat that is heavier than the bat actually used at bat, practice with a heavy bat, and after entering the bat, Due to the weight difference between the bat and the swing bat, the swing speed is increased, and measures for long hitting are widely taken.
[0003]
[Problems to be solved by the invention]
However, no matter how much the bat swing speed is improved, if the grip is not used properly, it will not be possible to make a correct swing and not only will not be able to get a long hit as expected, but also because the swing speed has been improved, There is a problem in that an excessive load is applied to the hands, arms, hips, and the like, which may cause injury.
[0004]
Also, when trying to teach the correct bat swing for the purpose of preventing injuries and improving the long hitting rate, the key point is how to use the pusher and puller. Most batters do not need guidance on how to use the puller, and can easily provide guidance even when guidance is required.
Most batters who need to correct their swing must be taught how to use the pusher. Since the use of the pusher changes during the swing, it is difficult to understand even if the timing is explained verbally, and it is difficult to confirm the degree of mastery. There is also a problem that it does not go.
[0005]
The inventor of the present application searched for a bat for swing correction capable of learning a correct bat swing and searched in patent documents and the like and searched in a general market, but could not find any relevant information.
By developing a swing correction bat that can easily teach and learn how to use a correct grip during a bat swing, the present invention makes it possible to easily correct a wrong bat swing without risk of injury. Further, it is an object of the present invention to provide a swing correcting bat capable of improving a long hitting rate.
[0006]
[Means for Solving the Problems]
In order to solve the above problems and achieve the object, the present invention has the following configuration.
That is, the puller grip and the head are separated from each other and connected by a rod, and the pusher grip is disposed so as to be reciprocally movable along the rod between the puller grip and the head. A bat for correcting swings.
With this, when the bat is swung, if the correct swing can be made, the pusher grip and the puller grip collide at the time of impact and emit a sound, so that it is possible for another person to make a correct swing. This makes it easy to teach and learn the correct grip when swinging.
[0007]
Further, it is preferable that stoppers are provided at the upper end of the pull handle and the lower end of the push grip, respectively.
As the shape of the stopper, for example, a brim-shaped one can be used.
This eliminates the risk of injury due to the hand being caught between the pusher stopper and the puller stopper, and also makes it possible to increase the collision noise when the pusher stopper and the puller stopper collide. It is possible to clearly recognize that a correct swing has been made.
[0008]
Further, it is preferable that the rod is provided with an adjusting stopper that regulates a moving range of the push grip.
Thereby, the position of the push hand grip can be adjusted according to the skill level of the user.
Furthermore, it is preferable that the rod is provided with an external thread, and the adjusting stopper is screwed to the rod.
Thereby, the position of the push hand grip can be adjusted at an arbitrary position, so that the operating range of the push hand grip can be appropriately set according to the user's physique and skill level, so that a wide range of users can be targeted. Becomes possible.
[0009]
In addition, the puller in this specification means the hand which comes to the lower side when holding the bat, and the pusher means the hand which comes to the upper side when holding the bat. I have.
Specifically, in the case of a right batter, the puller is the left hand and the pusher is the right hand. In the case of a left batter, the puller is the right hand and the pusher is the left hand.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is an explanatory view showing one embodiment of the present invention, and is a perspective view showing a state where a pusher grip and a puller grip are separated from each other. FIG. 2 is a perspective view showing a state in which the push grip and the pull grip are in contact with each other. FIG. 3 is an explanatory cross-sectional view showing a connected state of the pull grip and the rod.
[0011]
The swing correcting bat 10 according to the present embodiment includes a pull grip 12, a head 14 corresponding to a head of the bat, a push grip 16, an adjusting stopper 18, and a rod 20.
As the material of the rod 20, a metal, a synthetic resin, a composite material, or the like can be used in terms of strength. The grip and the head can be made of wood, metal, synthetic resin, composite material or the like, similarly to the usual bat material.
[0012]
The pull grip 12 and the head portion 14 are connected by a rod 20 so as to be separated from each other. Female threads are formed at opposite ends of the puller grip 12 and the head section 14, and male threads 20a formed at both ends of the rod 20 are screwed. As described above, since the puller grip 12 and the head portion 14 are removably assembled, it is possible to prepare a plurality of types of puller grips 12 and head portions 14 having different sizes, weights, shapes, materials, and the like. This is preferable because it can be provided as a swing correcting bat suitable for a wide range of users having different physical strengths and skills from children to adults.
[0013]
The puller grip 12 is a grip part of a normal bat, and has a stopper 12a attached to an upper end thereof. The stopper 12a is prevented from being injured by being pinched by a pusher grip 16 arranged reciprocally between a head portion 14 to be described later and the stopper 16b of the pusher grip 16 is pulled by the puller handle. It is attached so that a collision sound is easily generated when the grip 12 collides with the stopper 12a.
In the present embodiment, the stopper 12a of the pull grip 12 and the stopper 16b of the push grip 16 are formed by brim-shaped rubber plates. However, the present invention is not limited to this. It is a matter of course that sound can easily be generated when 12a and 16b collide with each other and can be made of durable synthetic resin.
[0014]
The push grip 16 includes a cylindrical grip portion 16a and a stopper 16b. The grip portion 16a is formed in a hollow structure, and the rod 20 is inserted through a hollow portion of the grip portion 16a. Thereby, the push grip 16 can freely reciprocate between the head portion 14 and the pull grip 12.
The diameter of the hollow portion of the grip portion 16a is slightly larger than the diameter of the rod 20, and the pusher grip 16 is formed so as not to rattle. It can be performed.
Needless to say, the stopper 16b is provided at the lower end of the push hand grip 16.
[0015]
An adjustment stopper 18 for restricting the range of movement of the push hand grip 16 is provided between the head portion 14 of the rod 20 and the push hand grip 16. The rod 20 is formed with an adjusting male screw 20b for moving the adjusting stopper 18 in addition to the male screw 20a for connecting with the head portion 14 and the puller grip 16. The adjusting male screw 20b may be formed integrally with the male screw 20a for connection with the head portion 14 and the pull handle 16, or may be formed separately.
[0016]
The adjusting stopper 18 can be simply formed by a nut 18a having the same outer diameter as the outer diameter of the pusher grip 16 inserted through the rod 20, but the position of the nut 18a during repeated swinging is increased. May gradually shift, which may hinder learning of a correct swing.
Therefore, if a plurality of nuts 18a having the same outer diameter as the outer diameter of the push grip 16 are provided and tightened while the nuts 18a are in contact with each other, the position of the adjustment stopper 18 is shifted even after repeated swinging. This is preferable because it does not occur. Further, as shown in FIG. 1, if the adjusting stopper 18 is formed by tightening the nuts 18a from both sides of the washers 18b via the washers 18b formed to have a diameter larger than the grip, the operation of tightening and loosening the nuts 18a is achieved. Since the work is facilitated, the position of the adjusting stopper 18 can be adjusted more easily.
[0017]
In general, when making a correct swing at bat, the player must operate only with the puller from the start of the swing to immediately before the impact, and only after the impact, shake the pusher while pushing it against the puller. Has been a good swing. Hereinafter, a method of using the swing correcting bat 10 in the present embodiment will be described based on this theory.
[0018]
First, the pull grip 14 is connected to one end of the rod 20, and then the push grip 16 and the adjusting stopper 18 are inserted through the rod 20. Concatenate.
Next, the position of the adjustment stopper 18 is set according to the skill level of the user. Specifically, it is preferable that the moving amount of the push grip 16 is set to be small when a skilled user confirms the use, and the moving amount of the push grip 16 is set to be large for a beginner.
[0019]
When the user holds the assembled swing correction bat 10 and holds the swing, the pusher grip 16 slides to the position of the adjustment stopper 18. That is, the pusher and the puller are separated. Thereafter, the swing is started with the pusher and the puller kept apart, and the swing is performed such that the pusher and the puller collide at a position corresponding to the impact.
If the swing is correct, a collision sound is generated by the stopper 12a of the pull grip 12 and the stopper 16b of the push grip 16 at a position corresponding to the impact. By practicing the swing so that the collision sound is generated at a certain timing and the collision sound is increased, the correct use of the pusher and the puller can be learned.
[0020]
By practicing the swing described above while shifting the position of the adjustment stopper 18 and gradually narrowing the movement range of the push hand grip 16, it is possible to learn a swing using the pusher and the puller correctly. it can. In addition, as you practice, you will be able to swing correctly with the pusher and puller even with a normal bat, eliminating the risk of injury caused by the wrong swing, and improving the long hitting rate Can be.
[0021]
Although the swing correcting bat according to the present invention has been described in detail above, the present invention is not limited to this embodiment. Even if various modifications are made without departing from the gist of the invention, it is needless to say that the modifications fall within the technical scope of the invention.
For example, the stoppers of the pull grip 12 and the push grip 16 and the adjustment stopper 18 need not always be provided. In this case, if the end where the puller grip 12 and the pusher grip 16 collide is reinforced with a metal plate, a synthetic resin plate, or the like, a collision sound is easily generated and the grip is prevented from being damaged. Can be.
Further, if the head portion 14 is made longer and the rod 20 is made shorter without providing the adjusting stopper 18, the moving amount of the pusher grip 16 becomes smaller, and the shape becomes closer to a normal bat shape. Since it can be used for batting and free batting, it is possible to practice in a form closer to practice.
[0022]
【The invention's effect】
According to the present invention, since the movable pusher grip collides with the fixed puller grip and makes a collision sound, when a correct swing is made, the collision sound is output at a position corresponding to the impact. Since it is possible to confirm whether or not the correct swing has been performed not only by the person who performed the swing, but also by the surrounding people, it is possible to easily perform the guidance and acquisition of the correction of the swing.
[0023]
Further, since the puller grip and the pusher grip are provided with the stoppers, there is no risk of the hands being pinched during the swing practice, and the collision noise generated at the time of impact can be increased.
In addition, the rod is provided with an adjustment stopper that regulates the range of movement of the pusher grip, so that the position of the puller grip can be set according to the user's physique and skill level. Can be done.
Furthermore, since the adjusting stopper is screwed to the threaded portion formed on the rod, a remarkable effect such as that the position of the adjusting stopper can be easily adjusted can be obtained.
