Abstract

(57) [Summary] (Corrected) [Purpose] From the start of the pitcher's pitching motion, the speed of the ball is reproduced by moving the light source, and the batter recognizes the ball speed and can practice hitting and reaches the home base. We provide a baseball batting practice device that allows you to check the moment you make a sound. [Arrangement] The time for passing between the light emitters 1 is set by an oscillator 3, and a signal from the oscillator 3 activates a counter unit 5 to drive a drive unit 6.
When the light-emitting body 1 that is currently turned on is turned off, the light-emitting body 1 in the next stage is turned on, and a plurality of light-emitting bodies 1 whose lighting positions are sequentially moved and a sounding body 2 that finally emits a sound are provided. A control unit 4 for controlling start and stop is provided. The present invention is characterized in that a changeover switch A14, a changeover switch B15, and a changeover switch C16 are provided for selecting a moderate or rapid ball speed.

Description

[Detailed description of the device]     [0001]   [Industrial application]   This invention relates to a baseball batting practice device.     [0002]   [Conventional technology]   Conventionally, since there is no practice device for the batter to recognize the speed of the ball and swing, Recognizing that, I couldn't practice hitting the bat.     [0003]   [Problems to be solved by the device]   In this way, because the batter cannot recognize the speed and trajectory of the ball and practice batting , Bat before the hitting position of the batter corresponding to the speed and trajectory of the ball I couldn't let the body remember if I could hit the ball.     [0004]   [Means for solving the problem]   Specify the distance between the attached objects and set the time for the ball to move with the oscillator 3. To do. The signal from the oscillator 3 for setting the speed of the ball causes the counter unit 5 to operate. When the drive unit 6 is activated and the light-emitting body 1 that is currently lit is turned off, the light-emitting body 1 in the next stage is A plurality of light emitting bodies 1 which are turned on and whose lighting positions are sequentially moved, and a sound producing body 2 which finally emits a sound are provided. Set up. A control unit 4 for starting and stopping is provided.   It is a baseball batting practice device having the above configuration.     [0005]   [Action]   The control unit 4 controls the signal from the oscillator 3, and the counter unit 5 operates to drive the signal. The moving part 6 operates, and the light emitter 1 and the sounding body 2 operate.     [0006]   [Example]   Example 1   Hereinafter, examples of the present invention will be described.   FIG. 6 is a block diagram of an electric circuit.   First, the signal from the oscillator 3 is used as the start signal of the control unit 4, and the counter unit 5 is started. Drive, the drive unit 6 lights the first light emitter 1, and the lighting position moves in sequence, The sounding body 2 emits a sound. Next, the operation is terminated by the stop signal of the control unit 4.   FIG. 1 is a perspective view showing the first embodiment.   As a place to install this, the sounding body 2 is attached to the upper part of the pillar 9, and the home base 7 put on top. On the pitchers plate 8, a plurality of light emitters 1 are provided on the support column 9. Place. The pitch 9 between the pitchers plate 8 and the home base 7 is evenly spaced. Let go. Further, the height of the light emitting body 1 is on the trajectory of the ball.   The batting practice device body 10, the light emitter 1 and the sounding body 2 are connected by a cable 11.   The movement from the start of the pitcher's pitching motion to the release of the ball from the pitcher's hand This can be reproduced by the lighting movement of the plurality of light emitting bodies 1 on the plate 8.   Depending on the ball speed from when the ball leaves the hand until it reaches the home base 7 The lighting movement time can be obtained by adjusting the frequency of the oscillator 3.   When using this, turn on the power switch 12 and set the frequency according to the ball speed. Then, the oscillator 3 is adjusted by the changeover switch A14. Plural on Pitchers Plate 8 The light-emitting bodies 1 of the above are sequentially turned on and moved, and finally the sounding body 2 on the home base 7 emits a sound. It Determine the position of the batter's bat 13 at the moment when the sound is emitted By doing so, the slowness of swinging of the bat 13 can be properly confirmed.   In this way, from the start of the pitching action of the pitcher until the ball reaches the home base 7. You can reproduce the state with light and sound, and you can select the desired ball speed. Therefore, the ball at the pitching speed of the pitcher is visually recognized as the movement of the light source and reaches the home base 7. By listening to the sound when it reaches, you can practice hitting assuming a real match.   Further, the adjustment switch A14 and the switch B15 are provided to adjust the oscillator 3. By switching the switch C16, it is possible to select the speed of the ball.     [0007]     Example 2   FIG. 2 is a perspective view showing the second embodiment. In the case of Example 1, the color of the light-emitting body 1 Is single. In the second embodiment, the display color of the light emitter 1 is set to a plurality of colors such as red and blue. By using it, it is possible to visually confirm at which position of the light emitter 1 the bat 13 should be started to swing. Recognition becomes easier.     [0008]     Example 3   FIG. 3 is a perspective view showing the third embodiment. Example 3 is used under daylight At the time of lighting, by covering the light-emitting body 1 with the cover 17 to create a shade, light is emitted even in the daytime. The light of the body 1 can be visually confirmed, and can be used for daytime batting practice.     [0009]     Example 4   FIG. 4 is a perspective view showing the fourth embodiment. Example 4 is for indoor use Therefore, the pillars 9 to which the light emitter 1 and the sounding body 2 are attached are installed with a narrow interval.   The interval is shorter than that in the first embodiment, but the time interval is the same, so the moving time of the light source is The sound generation time is the same as that in the first embodiment.   The method of use is the same as in Example 1.     [0010]     Example 5   FIG. 5 is a perspective view showing the fifth embodiment.   The fifth embodiment is provided with the light emitting body 1 which is turned on at the same time as the sound of the sound producing body 2.   This is for starting the lighting of the light emitter 1 on the home base 7 during slow playback of the video. The position of the bat 13 can be visually confirmed.     [0011]   [Effect of device]   The time it takes for the ball to reach the home base 7 from the start of the pitching motion If you feel that bat 13 hit the ball at the moment when the sound comes out, Equivalent to the timing when bat 13 can hit the ball in the ball game. It   By adjusting the frequency of the oscillator 3 according to the ball speed, the speed suitable for the individual I can practice. In addition, by adopting a plurality of colors such as red and blue as the display color of the light emitter 1, The position of the light source can be easily confirmed.   Also, during slow playback of the video, when the lighting of the light-emitting body 2 on the home base 7 is started, You can check the hitting position by checking where the position of the , Available as material for scientific training.
