Description

[Detailed Description of the Invention] This invention aims to help each person learn a regular pattern according to their physique, so that the swing of the bat that is used for batting is performed along the correct trajectory, and also with the strength of the batted ball. This is a batting practice machine whose purpose is to provide equipment for learning batting skills.

Conventionally, in batting practice, it is common for players to take practice swings under the guidance of a coach, but it is not always difficult to capture the trajectory of the swing starting position, batting position, swing position, etc. However, there was a problem in that the correction of each person's form also lacked precision.

In addition, since the strength (as well as the direction of the ball) at the time of hitting the ball is unknown in the practice swing, the quality of the swing is determined by the individual's own feeling, which is inaccurate.

However, batting form cannot be improved by thinking or thinking, and unless each person learns it physically, good results cannot be expected.In order to acquire a good form, each person must repeat a good form. I needed to practice.

However, in the present invention, a guide path through which a bat passes during batting is installed so as to be adjustable in height and angle, a ball is movably faced into the guide path, and the ball is linked with a striking force indicator. By setting the guide path for the bat in the correct form according to each person's physique, each person can use this practice device to swing the bat and naturally acquire the correct form that suits them. can.

The bat passage guide path mentioned above can be easily obtained by determining it through precise calculations and experience by experts, and can be adjusted based on the user's physique. It can be described as a versatile machine. In addition, the training aircraft of this invention is a fixed type at a dedicated training range,
A mobile type is used indoors and other locations where the line practice location changes. Next, when it is necessary to measure and display the speed of the roses 1 to 1, photoelectric devices 32 and 33 are installed at two locations before and after the guide path.
When the first light beam is interrupted, the output point of the next light tQ'argi is used as input, and the display unit 34 electrically displays a rose 1.
The speed of - can be calculated and displayed.

That is, if this invention is explained with reference to an embodiment, wheels 2.2
The support columns 3.4.5 are planted on the peripheral edge of the base plate 1, and the support columns 3.4.
An elevating rod 6.7 is fitted into the upper part of 5 so as to be able to rise and fall freely, and can be fixed at an arbitrary height with thumbscrews 8.8. Pillar 4
A lower arm rod 10 with a rack 9 is fitted into the upper end of the rack 9 so as to be movable up and down, the rack 9 meshes with a pinion 11 on the upper side of the support 4, and a handle 13 is fixed to the shaft 12 of the pinion 11. Further, the upper part of the support rod 14 is rotatably attached to the upper end of the lifting rod 10 by a gun 15, and the lower part of the support rod 14 is formed in a fan shape, and an arcuate groove 16 is bored inside the fan shape. The bolt 17 of the lifting rod 10 is inserted into the hole 16, and the lifting rod 10 and the support rod 14 are fixed with a wing nut 18. Further, lower guide rods 19 for forming a guide path A through which the roses 1 to 29 pass during batting are fixed to the upper parts of the lifting rods 6.7 and the support rods 14, respectively, and the guide rods 19 have a U-shape. The upper guide rod 20 is fixed at regular intervals via support pieces 21.21a and 21b.

The ball 22 is facing the middle part of the guide path formed by the guide rods 19 and 20, and the support rod of the u1 ball 22 is indicated by the indicator 23.
It can be freely rotated and removed. The display 23 is attached to the base plate 1 by a support 24, and the display 23 has a built-in device that measures the rotational force of the support rod 27 of the ball 22 and displays it numerically, and can be used as a pointer display or digital display. Blow]
is now displayed. Furthermore, the direction of the ball can be indicated by the angle of the bat when hitting the ball and the angle of contact with the ball. 25 in the figure is a board established at one end of the plywood.
If a mirror is installed, the user's entire body can be reflected in the swing position. Further, 26 is a roll-up type sheet that can be pulled out and placed over the top.

In the embodiment, when the user 30 steps on the base plate 1,
The spring 28 contracts and the base plate 1 moves as shown by the chain line in FIG.
It descends as indicated by arrow 31 to position a, and its lower surface contacts the floor and is stabilized. Therefore, the bat 2 is placed at one end of the guideway.
If you hold the bat so that one end of the 9 is in the middle and swing the bat along the guide path, you will get the correct form. Therefore, by repeating this kind of practice swing, you can master the correct form.

In the above, by rotating the handle 13 to determine the height of the lifting rod 10 fitted into the support column 4, the height of the guide path is adjusted to the user's physique, the angle of the support rod 14 is tilted, and the guide path is adjusted. By changing the angle of the path as indicated by the chain line a or b in FIG. 1, the horizontal swing guide path can be adapted to either upswing or downswing. In addition, a rubber collar 32 is fitted to the rose 1 and 29, and the butt 29 is attached to the branch pieces 21.21a, 21.
Regulations are made so as not to collide with b.

That is, according to the present invention, since the guide path through which the bat passes during batting is provided so as to be adjustable in height and angle, by practicing swinging using the guide path, it is possible to easily master the correct batting form. In addition, since the ball is placed in front of a part of the guide path, the player can learn the feeling of hitting the ball and also know the strength of the hit.
