Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing straightening device adapted to wear a swing suitable for various courses of a ball when practicing batting of softball or baseball.

[0002]

2. Description of the Related Art Swinging is the most important subject in batting practice mainly in juvenile baseball and high school baseball. As a method of practicing this swing, it is common to perform a swing based on the image of the batter's own form, timing, etc. in addition to the ball hitting point, course, and pitch type.

[0003] In such a swing, the difference in skillfulness becomes large depending on the image of the batter himself, and there is a great difference in the degree of improvement depending on whether or not there is a sense.

On the other hand, instruments for practice of actually improving the swing while hitting the ball have been widely used. As an example of this, for example, Shoukai 58-1
There are those described in Japanese Patent No. 24174 and Japanese Utility Model Laid-Open No. 62-21383.

The basics of these instruments are that a ball is set on a pitching course and the stationary ball is hit by a batter with a bat. In the conventional practice method, a coach or the like evaluates the swing and form at the time of practice to improve the swing.

The swing when actually striking the ball with the batting practice machine instead of the stationary ball is also based on the observation and advice from others.

[0007]

The most important point in batting, whether it is a beginner or a person with a certain degree of skill, is
Rather than reading the pitch or course, the bat's head is well off after catching the ball. That is, in a series of movements from the backswing, the body weight movement is performed in conformity with the course of the ball and the desired direction, and whether or not the follow through is appropriate as a result determines the quality of batting.

However, although the conventional practice equipment and batting practice machine can practice hitting the ball itself, it does not have a function of correcting it until the follow-through. That is, although the batter's swing with respect to a ball that is stationary or a ball that is actually pitched can be observed by a coach or the like, research and practice of the batter's own follow-through are practically impossible.

[0009] Therefore, an object of the present invention is to provide a swing straightening device capable of surely learning the most important follow-through in a batting swing.

[0010]

SUMMARY OF THE INVENTION According to the present invention, a front target and a follow target are arranged in order on a trajectory of a bat head of a swing from a backswing of batting to a follow through, and a plane positional relationship and a vertical position of these targets are arranged. It is characterized in that the positional relationship can be set arbitrarily.

[0011]

When the batting swing is practiced, the front target is positioned on the locus of the bat head, and the front target is swung as if it were a ball actually hit. Then, the bat head swings toward the follow target located between the hit and the completion of the follow through.

By changing the position of the front target arbitrarily, it is possible to set a combination of the inner angle, the outer angle, the height, and the height of the strike zone, so that the bat head is directed to the follow target depending on which direction and how the ball is hit. Correcting the swing improves the quality of batting.

1 is a perspective view showing the outline of a swing straightening apparatus according to the present invention.

In the figure, three posts 2a, 2b and 2c are connected on a frame 1 as a multi-tube structure, and the lower 2
The upper two posts 2b, 2 are screwed into the upper ends of the two posts 2a, 2b by the adjusters 3a, 3b.
The height of c can be adjusted.

An arm 5 is connected to the upper end of the post 2c by a joint 4. The joint 4 is in the form of a sleeve having an inner diameter that allows the arm 5 to freely move and rotate, and is provided with two fixing screws 4a for pressing the peripheral surface of the arm 5 and fixing it to the joint 4. is there.

A bar 6 is attached to the arm 5 by a joint 6.
To connect. As shown in FIG. 2, the joint 6 integrates two pipe-shaped sleeves 6a and 6b in a direction in which their respective axes are orthogonal to each other, and
6b is provided with adjusting screws 6c and 6d which can be manually rotated from the outside. The arm 5 is inserted into one sleeve 6a and the adjusting screw 6c is tightened to fix the joint 6 to the arm 5, and the other sleeve 6a
The bar 7 is passed through b and the bar 7 can be fixed by the adjusting screw 6d.

A joint 7a having the same structure as the joint 6 is provided on the tip side of the bar 7, and a wire 7b is hung on the joint 7a. It is suitable that the wire 7b is relatively hard, and the wire 7b is put in the sleeve 7c of the joint 7a and tightened and fixed by the adjusting screw 7d. The wire 7b may be directly tied to the tip of the bar 7 without providing the joint 7a.

At the lower end of the wire 7b, there is a front target 8 corresponding to an actual ball when practicing batting.
To provide. The front target 8 may be, for example, a vinyl string-shaped one that is hung in a streamer shape, and it is preferable that the impact when the bat hits is not transmitted to the wire 7b side. In addition to this, a rubber ball or the like corresponding to the actual size of the ball may be applied.

Further, a joint 9 is provided on the upper end of the post 2c. The joint 9 has a structure similar to that shown in FIG. 2, and has two sleeves 9a and 9b provided with adjusting screws 9c and 9d, respectively. Then, one sleeve 9a is attached to the post 2c so that it can be fixed at a free height by the adjusting screw 9c, and the bar 10 is inserted into the other sleeve 9b to insert the adjusting screw 9c.
Fix by d.

The bar 10 is longer than the bar 7 for the front target 8. A wire 10b is attached to the tip of the bar 10 through a joint 10a, and a follow target 11 is provided at the lower end of the wire 10b. The follow target 11 is exactly the same as the front target 8 and prevents the impact when the bat hits from being transmitted to the wire 10b.

Here, the front target 8 corresponds to the actual course of the ball when practicing batting, and the follow target 11 is an optimum follow through for various batting methods when hitting the front target 8. The batter's swing is corrected by positioning the bat on the trajectory of the head of the bat. Therefore, it is necessary to set the positional relationship between the front target 8 and the follow target 11 in various ways. By operating the joints 6, 9, 7a, 10a, the length and direction of the bars 7, 10 and This is possible by changing the hanging length of the wires 7b and 10b.

3 and 4 are skeleton diagrams schematically showing the position setting of the front target 8 and the follow target 11 as described above. In these examples, the frame 1 is set on the right side of the home base 50 and is set for practicing a right-handed batter.

When setting the frame 1,
In order to confirm the positional relationship with the hose base 50, it is preferable to provide the bar 7 with a scale 7e as shown in FIG.

In the example of FIG. 3, the front target 8 is located in the middle of the strike zone, and the follow target 11 is located diagonally below and to the left of the front target 8. This kind of setting is equivalent to the practice of batting to bounce the ball toward the middle left direction.

Further, in the example of FIG. 4, the front target 8 is set at a lower inner angle, and the follow target 11 is in the center direction and is located at the upper right position. In this case, this is a practice of scooping up the ball at the batter's knee and hitting it back with the fly or liner in the right middle direction.

In addition to such an example, the front target 8
By changing the two-dimensional positional relationship and the vertical relationship of the front target 8 in various ways, it is possible to practice corresponding to various ball courses, and the batter himself can perform intensive practice on weak courses.

6 to 9 are views showing the outline of the pattern of the actual practice.

FIG. 6 shows the front target 8 at a higher center position.
Is set, and the follow target 11 is located diagonally below and to the left of the batter. This is equivalent to the practice of hitting a ball with a higher outside angle back to the center left by hitting the head of the bat 20 against the front target 8 as shown in (a) of the figure, and as the follow target 11 as shown in (b) of the figure. By hitting the head, the swing is corrected with proper follow-through.

FIG. 7 shows an example of a case where the front target 8 set at a higher center is hit back in the right middle direction, and the practice method for straightening is the same as in the case of FIG.

FIG. 8 and FIG. 9 are examples in which the left batter is practicing to hit a high ball back with a goro.

In FIG. 8, the head of the bat 20 is brought into contact with the front target 8 by the back swing of (a) to the swing of (c), and the swing is executed so that the head goes to the follow target 11. Then, as shown in FIG. 9A, the head of the bat 20 is swung so as to hit the follow target 11, and it is understood that the correction up to the follow through in FIG. 9C is performed.

As described above, by changing the positional relationship between the front target 8 and the follow target 11, it is possible to correct the swing suitable for the course of the ball and the striking direction. Practice can be done.

In the illustrated example, two bars 7 and 10 are provided, but it is also possible to increase the number of these bars so that two people can practice together.

FIG. 10 is a perspective view of a correction device showing another example.

Similarly to the previous example, one post 13 is connected to the frame 12 by the adjuster 12a so that the height of the post 13 can be adjusted, and two joints 14 can be adjusted in height by the adjuster 14a. Incorporated. Rods 15 and 16 are inserted into these joints 14, respectively, and their positions in the axial direction can be freely changed and fixed by an adjuster 14b. Further, the front target 17 and the follow target 18 are suspended from the tip ends of the rods 15 and 16 by wires as in the previous example.

Also in this example, by changing the mutual positional relationship between the front target 17 and the follow target 18, it is possible to practice the batting swing correction suitable for various ball courses. Also, post 13
Two batters can be practiced by adding two joints to and connecting rods to them.

[0037]

According to the present invention, the swing up to the follow-through of the batting can be corrected by assuming the various pitched balls, by following the positional relationship between the two targets. For this reason, compared to the conventional batting practice of hitting just the equivalent of a ball, practice of proper swing including weight transfer can be performed efficiently, and it can be used in a wide range from juvenile baseball to adults. It will be possible.
