Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for practicing exercise equipment such as golf clubs, baseball bats, tennis rackets, kendo bamboo swords, hammer throws, hockey sticks, hanging poles and the like, which are used by players swinging. This is a training machine that informs a competitor of the timing at the moment of the maximum head speed in a competition, and displays the speed value and the quality of the swing.

[0002]

2. Description of the Related Art Conventionally, in sports such as those described above, a training machine for improving the head speed has been such as swinging the tool on a continuous photograph or on a fixed type device. There was no indication of the timing of the maximum speed, nor was there any immediate indication to the competitor of the maximum head speed value and the quality of the swing.

[0003]

SUMMARY OF THE INVENTION The present invention relates to a tool such as a baseball bat or a golf club, which uses the "shake" operation itself to determine the maximum head speed value, swing quality and timing. You can know in real time (every moment you shake),
It is intended to provide a training machine with a high training effect. )

[0004]

SUMMARY OF THE INVENTION The present invention relates to a sensor for measuring acceleration in a direction in which centrifugal force is generated by a circular motion as shown in FIG. Control unit with acceleration sensor 3 for measuring the acceleration in the tangential direction of the circular motion of the part, and acceleration sensors 4 for measuring the acceleration in the direction perpendicular to each of 2 and 3 respectively, and built in the main body based on the measured accelerations 5, the head speed and the quality of the swing are calculated. Similarly, from the measured acceleration value and the rate of change of the value, the instant of the maximum value of the head speed is displayed by the LED 7 arranged on the surface of the main body in a large amount of light, and attached to the main body. A sound is generated by the speaker 9 to inform the trainee of the timing, and then the L arranged on the surface of the main body
The ED 8 displays the maximum head speed value and the quality of the swing, and the speaker 9 displays the maximum head speed value and the quality of the swing by voice. In addition, about the tool to swing down such as a bamboo sword shown in FIG.
With regard to the color display by adjusting the light emission amount, the correspondence of the head speed by the color is determined in advance, and the maximum head speed can be known by calculation and display.

[0005]

According to the present invention, since the above-mentioned means are taken, when using the bat or the golf club, a tool such as a bat or a golf club is placed in a direction in which the trainee can see the surface on which the LEDs 7 and 8 and the speaker 9 are arranged (usually). Each time you shake, the trainee will be notified of the moment when the maximum speed is reached by light and sound, and the speed will be displayed by light and sound.

[0006]

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

As shown in FIG. 2, the head speed measurement in this embodiment measures the circular motion of the head portion around the grip generated when the instrument is shaken by three acceleration sensors attached near the head of the main body. The centrifugal force is measured by an acceleration sensor, and the maximum head speed, its instant, and the quality of the swing are calculated and displayed from the centrifugal force and its change rate.

As shown in FIG. 3, the maximum head speed and the moment measured and calculated by the acceleration sensor are displayed by the LED light emitting element 7 and the speaker 9, and the maximum head speed is indicated by the LED. Numerical display by the element 8 (such as expressing the numerical value by spatial movement of the LED 8 array as shown in FIG. 3) and voice display by the speaker 9 (speaking "125 km" by voice synthesis). is there.

[0009]

The present invention provides a golf club swing,
When using a tool used by swinging a baseball bat such as a swing, the practice is effective by displaying the maximum head speed, its timing and the quality of the swing to the competitor in real time and making them aware. is there.
