Abstract

<P>PROBLEM TO BE SOLVED: To provide a training apparatus for practice swing, allowing a user to master a strong and stable form without a shake for swinging out by rotation of the body at the minimum distance and attaining a long carry of a ball by a series of swinging operations from a small orbit to a large orbit to swing the bat in an elliptical orbit. <P>SOLUTION: In this training apparatus for practice swing, a member is provided at the base end part and the tip part of a shaft, and a grip is provided to move along the axial direction. The grip is moved from the tip part to the base end part by a series of operations to vary the fulcrum, thereby making a change from a small orbit to a large orbit. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a swing training device that can be used by anyone anywhere in order to improve skills or to eliminate lack of exercise in a ball training practice of hitting a ball using a hitting tool such as baseball, tennis, golf, or table tennis. It is about.

  In general, the practice of swinging such as baseball, tennis, golf, table tennis, etc., simply swings a bat, a racket, or a trainer that applies centrifugal force.

  However, in the practice of swinging with the hitting tool described above, the fulcrum is constant, so it tends to be a circular orbit, and the important swing is learned from the swing of the elliptical trajectory of “from inside to outside” that swings greatly from the impact at the shortest distance. It was very difficult. In addition, there is a problem in that the center of gravity at the front end portion tends to make a detour, and if the user is not conscious, the side is not tightened and the hand is easily hit.

  In addition, the swing exerciser in which the weight moves has a drawback that the weight tends to make a detour because the weight moves from the proximal end side to the distal end side by centrifugal force.

  For example, in baseball batting practice, a short bat is suitable for catching the ball with certainty, and a long bat is suitable for flying the ball far away because centrifugal force is utilized. There has been a demand for a swing exerciser that can perform these two different batting techniques by a series of swing movements.

  In order to solve the problems of the present invention, the swing training device of the present invention according to claim 1 is characterized in that members are provided at the base end portion and the tip end portion of the shaft, and the grip is movable along the axial direction of the shaft. In the swing training device provided with the grip, the grip is on the tip side when swinging, and the grip moves from the tip side to the base end side by a series of swing operations, changing the fulcrum and changing from a small track to a large track did.

  According to the swing training device of the present invention according to claim 1, it is difficult to acquire from the inside (outside out), which is difficult to acquire even if it is conscious by a change of a large orbit from a small orbit in a series of swing operations. ) Swing can be easily obtained, and the hitting technique can be improved.

  In addition, the fulcrum changes due to impact while maintaining a fast speed in a small orbit, and the acceleration is increased by a greater centrifugal force, greatly increasing the swing speed.

  For example, in the practice of baseball swinging, when you hold it, it will be like a weight under a short bat, it is easy to start from the lower body because the head side is light and the center of gravity is at the bottom, the side is tightened naturally You can make a stable foam without shaking the swing axis.

  In addition, even if a little sound is generated when the grip moves from the distal end to the proximal end and hits the proximal end, the bat will sound as soon as it comes out from the outside, so you just need to be aware that you want to make a sound in front , You can naturally learn to feel the bat in the shortest distance compactly.

  For example, in the case of baseball, the swing is changed from a short bat to a long bat in a series of actions, so you can learn how to use the body naturally. It can be swung out in the shortest distance, and can respond to both fast balls and slow balls, improving the meet power. Since a large trajectory can be drawn from the impact, the ball can be carried far away, and the hitting rate and flying distance can be increased.

  The practice machine in which the weight is moved from the proximal end side to the distal end side by centrifugal force has a drawback that it tends to make a detour. However, according to the swing exerciser of the present invention according to claim 1, the grip is conversely the distal end part. Since it moves from the base end to the base end, it is possible to obtain a strong and stable foam that is inward and has no blurring due to shaft rotation.

  The present invention will be described below with reference to embodiments shown in the drawings.

  FIG. 1 to FIG. 2 show an embodiment of a swinging bat to which a swing training device according to the present invention is applied. FIG. 1 is a diagram showing the overall configuration, and FIG. 2 shows a state when actually used. FIG.

  The practice device for swinging of the present embodiment illustrates a baseball swinging bat.

  As shown in FIG. 1, a baseball swing bat 1 as a swing training device of this embodiment has a shaft 2 formed in a straight line. A head hitting member 3 at the tip of the shaft 2 is provided. A base end hitting member end 5 of the shaft 2 is provided. A grip 4 that is movable along the outer peripheral direction of the shaft 2 is provided.

The shaft 2 of the present embodiment is formed of a material such as a stainless steel pipe, for example, in a cylindrical shape having an outer diameter of about 19 mm, a thickness of about 1 mm, and a length of about 1 m. The distal end head 3 and the proximal end 5 are firmly fixed to the shaft 2 so that a fixing pin penetrates in the radial direction.
The gap between the shaft 2 and the grip 4 is set to about 1 mm so that the grip can move smoothly. The moving distance of the grip 4 is set to about 8 cm to 10 cm so that it can be swung out in the shortest distance. A weight is built in so that the balance comes to the center.

  FIG. 2 is a diagram illustrating a state in actual use. Since the grip 4 is on the distal end side 3 in the prepared state 1, it becomes a state in which a weight is attached to a short bat (with a small trajectory) and can be swung out at the shortest distance. At the meet point, the grip moves from the distal end side 3 to the proximal end side 5 and changes to a long bat so as to draw a large trajectory. Further, since the grip 4 moves from the distal end side 3 to the proximal end side 5, it becomes an inward rotation and rotates around the body axis, so that a strong and stable foam without blur can be obtained.

Claims (1)

In a swing training machine where members are provided at the base end and tip end of the shaft, and a grip that can move along the axial direction is provided, the grip moves from the tip end side to the base end side when swinging. The swing exerciser is characterized by the fact that the fulcrum is changed and the robot swings in an elliptical orbit that changes from a small orbit to a large orbit by a series of movements.
