Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hitting tool-type muscle strength training machine for ball games that trains muscle strength when swinging clubs, rackets, and bats for golf, tennis, baseball, and the like.

In order to improve at a sport such as golf, it is necessary to go out on the course and practice many times, but in reality, going to a golf course or practice range every day is not necessary. There are practice machines and equipment that allow you to practice by swinging a golf club, as well as exercise the muscle strength necessary for golf, but these require space and are mostly designed for outdoor use, so golf club-shaped devices are used both indoors and outdoors. There aren't many things you can practice with.

This invention was made in view of these points, and consists of a training machine in the shape of a golf club, tennis racket, baseball bat, etc., and one end of the training machine is attached to an appropriate object in the posture during a golf shot. While measuring and displaying the pressurizing force when pressed, a timer is installed to maintain this pressurized state for a desired time, and the pressurizing force when shaking the training machine by switching a switch etc. is measured and displayed. The purpose of this machine is to provide a hitting tool type muscle training machine for ball games that allows players to easily train their muscle strength for shots and hits indoors and outdoors while enjoying the atmosphere of golf, tennis, baseball, etc. It is something that can be done.

Embodiments of the present invention will be described below with reference to the drawings. 0 FIGS. 1 and 2 show a first embodiment of the present invention, 1 is a golf club, 2 is a head provided at the tip of the shaft 3 of this golf club 1. A pressurizing force measuring device is built into the head section 2. Reference numeral 4 denotes a pressure-sensitive element provided on the shot surface of the head portion 2. This pressure-sensitive element 4 is made of, for example, pressure-sensitive conductive rubber, and the pressure applied to this pressure-sensitive element (WJ
In Figure 2, it has the function of replacing changes in pressure P) with changes in resistance. 4a is the center point of the pressure sensitive element provided at a position corresponding to the sweet spot of the head portion 2. Reference numeral 5 indicates a display window provided on the top surface of the head section 2 for displaying the pressure force measured by the above-mentioned pressure measurement device; 6 is a set pressure changeover switch provided on the top surface of the head section 2; and 7 is a display window provided on the top surface of the head section 2. This is a timer selector switch provided on the top surface that allows you to select the operating time of the buzzer that sounds when a pressure greater than the set pressure is measured. Reference numeral 8 designates an air intake port provided on the shot surface beside the pressure-sensitive element 4, and reference numeral 9 designates a circuit changeover switch provided on the upper surface of the head portion 2 for selecting the mode of use of the present invention. FIG. 2 shows the configuration of the above-mentioned pressure measuring device, in which the resistance changes due to changes in the force applied to the pressure-sensitive element 4 and the pressure P, and this changes the voltage. Measure. Reference numeral 11 denotes a display element such as an LCD that digitally converts this measured voltage and displays it as a pressure force.The display element 11 displays the pressure force in the display window 5 of the head section 2. 12 is a voltage comparison circuit that compares the set voltage corresponding to the pressurizing force set by the set pressurizing force changeover switch 6 with the measured voltage, and outputs an output if the measured voltage is equal to or higher than the set voltage level. Voltage comparison circuit 12
A transistor 14 which is turned on by the output of the transistor 13 is a timer circuit which is activated by turning on the transistor 13, and a buzzer 15 is sounded according to the time set by the timer circuit 14.

This set time can be selected using the timer changeover switch 7. Reference numeral 16 denotes a sound or vibration generator provided in the air intake hole 8 provided in the head portion 2. This sound or vibration generator 16 is composed of, for example, a whistle or a suitable vibrator, and generates air when the club 1 is swung. When you suck on it, a whistle sounds or a vibrator vibrates. 17 is a sound or vibration sensor that detects the sound or vibration of this sound or vibration generator 16, 18 is a voltage conversion circuit that converts the magnitude or amplitude of the sound detected by this sound or vibration sensor 17 into a total voltage, and 19 is a This is an amplification circuit that increases the output voltage of the pressure sensitive element 4 or the voltage conversion circuit 18 by [1] and sends it to the voltage measurement circuit 10. The circuit changeover switch 9 causes the changeover switches 9a and 9b to interlock with each other, and in the case of the solid line shown in FIG. 19 is connected. Moreover, in the case of a dotted line, the pressure sensitive element 4 is connected to the voltage measuring circuit lo via the amplification circuit 19. The above components are built into the head portion 2 of the club 1.

In the case of this embodiment, in order to press the club 1 against an appropriate object and continuously strengthen the pressing force, first turn the club 10 circuit changeover switch 9 and change the changeover switches 9a and 9b to the second
Position it as shown in the solid line in the figure.

As shown in FIG. 3, the practitioner 2o holds the club 1 in a golf shot posture and presses the head portion 2 against a suitable fixed object 21 to apply pressure to the head portion 2. As a result, the sensing force of the pressure sensitive element 4 of the head portion 2 changes, and the resistance value changes. This is converted into a voltage, measured by the voltage measuring circuit 10, and digitally displayed on the display window 5 via the display element 11. At this time, the measurement display also changes as the pressing force changes. When the measured voltage reaches a voltage corresponding to the pressure set by the preset pressure changeover switch 6, the voltage comparison circuit 12 outputs an output, the transistor 13 is turned on, the timer circuit 14 is activated, and the buzzer 15 sounds. . The time for which the buzzer 15 sounds can be arbitrarily set in advance using the timer changeover switch 7.

In this manner, the buzzer 15 sounds for the set time when the practitioner applies the pressure he or she has arbitrarily set, so that the desired pressure can be maintained for the desired time. However, if the practitioner's posture is bad, the force will not be concentrated on the head portion 2 of the club 1, and it can be easily seen from the failure of the display window 5 and the buzzer 15 that the set pressure value will not be reached. In addition, the pressing force is not concentrated at the center point 4a of the pressure sensitive element 4 of the head section 2, and even if it deviates from the center point 4a, the pressing force value in the display window 5 does not increase.

Therefore, it is necessary to apply pressure to the so-called sweet spot of the head g152, where the posture at the time of shot,
It is possible to correct the place where force is applied.

In this way, by increasing the set pressure value and lengthening the duration while correcting your posture, you can increase the muscle strength used during club shots, increase the instantaneous force during actual club shots, and increase the flight distance of the ball. can be extended.

Further, when the head 2 is applied to a suitable fixed object 21 and pressurized in this way, the sound or vibration generator 16 hardly generates any sound or vibration, and the sound or vibration sensor 17 does not detect it. Therefore, only the pressing force P is measured by the pressure sensitive element 4.

Further, instead of the above embodiment, the timer circuit 14 may be turned on by the output of the voltage comparison circuit 12 when measuring the pressurizing force, and when a set time has elapsed, a signal is output and the buzzer 15 sounds. At this time, the practitioner must apply pressure while keeping the pressure value above a certain value while looking at the display window 5.
Since it is located in the head part 2, it corresponds to the ball position when shooting, and it is possible to maintain the correct posture when shooting and train muscle strength.

Further, if there is a large space inside or outside the room, it is possible to make a full swing of the club 1 and measure the pressing force at that time. That is, the switch 9a, 9b of the circuit changeover switch 9 is set to the position shown by the solid line in FIG. 2, and the practitioner holds the club 1 and swings it. When this shaking occurs, air enters the air intake hole 8 of the head part 2, and a sound or vibration is generated by the sound or vibration generator 16. This is detected by the sound or vibration sensor 17, and the loudness and amplitude of the sound are measured. The voltage is converted into a voltage value by a voltage conversion circuit 18, passed through an amplification circuit 19, measured as a pressing force by a voltage measurement circuit 10 and a display element 11, and digitally displayed on a display window 5.

At this time, the maximum pressure applied when taking the picture is recorded and displayed digitally. Furthermore, if you think that you cannot understand the image just by practicing swinging like this, switch the changeover switches 9a and 9b of the circuit changeover switch 9 to the positions indicated by the dotted lines in Figure 2, and place an elastic material such as rubber on the floor as shown in Figure 2. Swing the club 1 using the tongue n as a golf ball and strike it with the pressure-sensitive element 4 of the head part 2. P is applied 9, this voltage is measured by the voltage measurement circuit 10 via the amplification circuit 19, and this voltage is used as the pressure P to be applied via the display element 11 to the display window 5.
