Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to practice equipment for baseball and softball games,
In particular, the present invention relates to a bat swing training tool used to improve bat swing skills.

(Conventional technology) As a conventional bat swing practice tool.

There were structures shown in FIGS. 3 and 4.

That is, a square-shaped target board 1 is supported upright by a stand 2 so as to be able to move up and down, five arc tubes 3 indicating the strike zone are arranged in a distributed manner on the front surface of the target board 1, and a light emitting tube 3 is arranged at the center of the bat 4. The structure was such that a detector 5 was provided that emitted a sound when light from the arc tube 3 was detected.

(Problems to be Solved by the Invention) In the conventional device described above, it is possible to confirm that the bat 4 has passed through a predetermined strike zone by the sound of the detector 5; It was difficult to confirm which angular position within the batter's bat swing angle range the batter was at.

In other words, with the conventional one, it is difficult to confirm the distance between the target board 1 and the bat 4 that has arrived at the strike zone.

For this reason, the bat 4 is placed against the predetermined arc tube 3.

Even though it is an illegal swing if you swing at an angle that crosses the tip axis.

Detector 5 had a problem in that it emitted a normal sound.

Moreover, in the past, the arc tube 3 corresponding to the ball was located in front of the swing range of the bat, so the batter could not confirm the center point in advance, making it difficult for the batter to get a sense of the center of the pitch, which could discourage the batter from practicing.

Further, since conventional devices use electrical parts, they are expensive, easily damaged, and have the disadvantage that they can only be used in places where there is a power source.

The present invention has been made in view of the above circumstances.

To obtain an inexpensive bat swing practice tool suitable for promoting the acquisition of swing skills.

(Means for Solving the Problems) In order to achieve the above object, the present invention is constructed as follows.

That is, a frame is provided with both end portions extending laterally and facing each other while being spaced apart from each other in the vertical direction, and bar-shaped target members are provided at each end portion of the frame and are spaced apart from each other in the vertical direction, and at least one of the target members is connected to the other target member. The structure is such that an adjuster is provided to adjust the approach to the target member, and a stand is provided to support the frame in a vertically adjustable manner.

(Function) Since the present invention has the above structure, the distance between one fishing member and the other target member can be adjusted by, for example, moving one target member in the vertical direction by operating the adjustment tool. , this will set the passing gap for the bat.

In addition, by adjusting the vertical movement of the frame via the stand, one target member and the other target member move together in the vertical direction while maintaining the gap through which the bat passes, thereby allowing the bat to pass through. A strike zone of a predetermined height for the batter is set in the gap.

In this state, if the batter stands at a predetermined distance from the bat passage gap, the bat passage gap will be positioned relative to the batter in the up/down position, out/in position, and the swing of the bat when hitting the ball. The position of the three axes of angular position is exactly at the wick.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional side view of a main part showing an embodiment of the present invention.

Reference numeral 10 denotes a frame, which is made of a long metal material and is curved into a horizontal U-shape, with both ends 11 and 12 extending laterally and facing each other with a large distance in the vertical direction.

Rod-shaped target members 13 and 14 that face each other vertically are fitted into each of the ends 11 and 12 so as to be slidable in the vertical direction, and each target member 13 and 14 can be positioned at any position in the vertical direction. Adjusters 15 and 16 consisting of wing bolts for locking are provided.

Each of the above-mentioned members 13 and 14 is connected to each end 11 of the frame 10.
・Metallic pipes 13a and 14a fastened to 12,
It consists of elastic bodies 13b and 14b made of bellows rubber parts coaxially connected to these opposing surfaces.

A rod 10a is suspended and fixed to the lower part of the frame 10,
This rod 10a is slidably inserted into the support pipe 17a of the stud 17.

The rod 10a is locked to the support pipe 17a at any vertical position by a tightening bolt 17b attached to the side of the support pipe 17a.

Note that 17c is a base.

Next, the manner of use of the above embodiment will be explained.

First, operate the adjustment tools 15 and 16 to adjust the upper and lower target members 13 and 1.
4 in the vertical direction to set the distance between the elastic bodies 13b and 14b to a gap L1 suitable for the bat 5 to pass through.

Next, for tightening, the bolt 15b is operated to move the frame 10 in the vertical direction to set the height of the gap L1.

In this state, the batter stands up at a predetermined position to the left of the gap Ll in FIG.

As a result, the gap L1 is located at the intersection of three axes, that is, the vertical position, the out/in position, and the batting position in the traveling direction of the ball with respect to the batter, that is, the center point.

In this state, when the batter makes a normal swing and the bat 5 enters the gap L1 from a direction perpendicular to it as shown in FIG. 2(A), it will collide with the upper and lower target members 13a and 14. It passes smoothly through the gap Ll without any problems.

On the other hand, when the batter makes an abnormal swing and the bat 5 enters the gap L1 from an oblique direction as shown in FIGS. 2(A) and 2(T).

The chance of collision with the ends of the elastic bodies 13b and 14b becomes extremely high.

Further, when the bat 5 collides with any of the elastic bodies 13b and 14b, a sound is generated and the elastic bodies 13b and 14b generate sound.
14b will vibrate.

This allows the batter to visually and audibly confirm that the swing was illegal.

(Effects of the Invention) As is clear from the above description, the present invention can place a target at the center point of the batter, so the accuracy of detecting whether the swing is normal or abnormal is high, and You can clearly see the center point and practice your swing.

Further, since the present invention does not require any electrical components, it can be used even in places without a power source, which has the advantage of widening the scope of use, making it cheaper, and less likely to cause failures.
