As shown in FIG. 2, the first unit 10 includes a first piezoelectric element 11a and a second piezoelectric element 11b that generate electric power according to the applied pressure, a power supply circuit 12, and a signal wireless transmission unit 13 (signal output unit). doing. The power supply circuit 12 stabilizes the power obtained by the power generation while the first piezoelectric element 11 a and the second piezoelectric element 11 b are generating power, and supplies the power to the signal wireless transmission unit 13.

  The signal wireless transmission unit 13 includes a signal generation unit 131 and a transmission unit 132. The signal generator 131 generates a first pressure response signal using the power supplied from the power supply circuit 12 by the power generation when the pressurized first piezoelectric element 11a generates the power. The signal generator 131 also generates a second pressure response signal using the power supplied from the power supply circuit 12 by the power generation when the second piezoelectric element 11b to be pressurized generates power. The first pressure response signal is, for example, a two-pulse signal, as will be described later, and the second pressure response signal is, for example, a one-pulse signal, as will be described later.

  When the first piezoelectric element 11a generates power, the transmission unit 132 uses the first pressure response signal (for example, two pulses) generated by the signal generation unit 131 using the power supplied from the power supply circuit 12 by the power generation. Signal) is transmitted (output) in accordance with a predetermined wireless communication system. The transmission unit 132 also generates the second pressure response signal generated by the signal generation unit 131 using the power supplied from the power supply circuit 12 by the power generation when the second piezoelectric element 11b generates power (for example, 1 pulse signal) is transmitted (output) in accordance with the predetermined wireless communication method.

  In the first unit 10 having the above-described configuration, each of the first piezoelectric element 11 a and the second piezoelectric element 11 b has a function as a pressure detection unit and is used as a power source for the signal wireless transmission unit 13.

  As shown in FIG. 3, the second unit 20 includes a signal reception unit 21 (signal input unit), a signal generation unit 22, an output circuit 23, and a speaker 24. The signal reception unit 21 uses the first pressure response signal and the second pressure response signal transmitted from the first unit 10 (signal wireless transmission unit 13), and the wireless communication employs the signal wireless transmission unit 13 (transmission unit 132). Receive (input) according to the method. The signal generator 22 generates a first sound signal based on the first pressure response signal (for example, a two-pulse signal) in synchronization with the reception timing of the first pressure response signal in the signal receiver 21. The signal generator 22 also generates a second sound signal based on the second pressure response signal (for example, one pulse signal) in synchronization with the reception timing of the second pressure response signal at the receiver 21. . The first sound signal can be, for example, a sound signal that represents two intermittent short tones (pi-pi) corresponding to the first pressure response signal that is a two-pulse signal. For example, a sound signal representing one short sound (beep) can be obtained corresponding to the second pressure response signal which is a one-pulse signal.

  The output circuit 23 drives the speaker 24 based on the first sound signal and the second sound signal from the signal generation unit 22. As a result, the first sound based on the first sound signal (for example, two intermittent short tones (pi)) from the speaker 24 and the second sound based on the second sound signal (for example, 1) Two short tones are emitted.

  As shown in FIGS. 4 to 7, the first unit 10 is installed in a shoe.

  As shown in FIGS. 4 and 6, the first piezoelectric element 11a is embedded in a predetermined part (hereinafter referred to as a heel load part) E1 of the shoe 100 to which pressure is applied by the heel part of the foot FT. As shown in FIGS. 5 and 6, the second piezoelectric element 11b is embedded in a predetermined part (hereinafter referred to as a thumb load part) E2 of the shoe 100 to which pressure is applied by the thumb part of the foot FT. Specifically, each of the first piezoelectric element 11a and the second piezoelectric element 11b includes a shoe sole 101 (outer sole) and an insole 102 at the corresponding heel load site E1 or thumb load site E2, as shown in FIG. Embedded in the boundary.

  As shown in FIG. 6, the power supply circuit 12 and the signal wireless transmission unit 13 (the signal generation unit 131 and the transmission unit 132) in the first unit 10 are housed in one package. The foot FT is provided at a portion corresponding to the arch. Thereby, it is possible to avoid an extremely large force being applied to the package containing the power supply circuit 12 and the signal wireless transmission unit 13 during walking.

  For example, as shown in FIG. 8, the second unit 20 is attached to the user's arm. Thereby, the user who wears the shoes 100 provided with the first unit 10 can walk while listening to the sound emitted from the speaker 24 of the second unit 20.

  Next, the operation of the above-described walking training apparatus will be described with reference to the timing chart shown in FIG.

  A user who performs walking training wears the shoes 100 (see FIGS. 4 to 7) provided with the first unit 10 as described above, and wears the second unit 20 on the arm (see FIG. 8) to walk. Do. When the 3-step walking (see FIG. 1) is properly performed, if a load is applied to the heel load site E1 (see FIG. 4) of the shoe 100 by the heel of the foot during the walking (see FIG. 1 (a)). Then, pressure is applied to the first piezoelectric element 11a of the first unit 10, and the first piezoelectric element 11a generates power (see FIG. 9A). The signal generation unit 131 in the signal wireless transmission unit 13 that receives power supply from the power supply circuit 12 by the power generation of the first piezoelectric element 11a is synchronized with the start timing (pressure detection timing) of the power generation period T1 of the first piezoelectric element 11a. A two-pulse first pressure response signal is generated (see FIG. 9C), and the transmitter 131 transmits (outputs) the two-pulse first pressure response signal (see FIG. 9D). In the second unit 20, when the signal reception unit 21 receives (inputs) the two-pulse first pressure response signal transmitted from the first unit 10 (transmission unit 132) (see FIG. 9E), the signal generation circuit. 22 generates a first sound signal (representing intermittent two short tones) based on the first pressure response signal (two pulses) in synchronization with the reception timing (FIG. 9). (Refer to (f)). Based on the first sound signal, the speaker 24 driven by the output circuit 23 emits a first sound consisting of two intermittent short tones (see FIG. 9 (g)).

  When the load on the heel load site E1 of the shoe 100 by the heel of the foot decreases during the walking and a load is applied to the shoe 100 from the center of the sole (see FIG. 1B), the first piezoelectric element is applied. The pressure on the element 11a is reduced, and power generation at the first piezoelectric element 11a is eliminated. It should be noted that the first piezoelectric element 11a provided at the thumb load site E2 has not yet been applied with pressure enough to generate power. In this state, the first piezoelectric element 11a and the second piezoelectric element 11b do not generate power, and the first unit 10 does not supply power to the respective units, and does not perform signal generation and signal transmission operations.

  Then, when a load is applied from the foot during walking and a load is applied to the thumb load portion E2 (see FIG. 5) of the shoe 100 by the thumb of the foot (see FIG. 1 (c)), the first unit. Pressure is applied to the tenth second piezoelectric element 11b, and the second piezoelectric element 11b generates power (see FIG. 9B). The signal generation unit 131 in the signal wireless transmission unit 13 that receives power supply from the power supply circuit 12 by the power generation of the second piezoelectric element 11b is synchronized with the start timing (pressure detection timing) of the power generation period T2 of the second piezoelectric element 11b. A one-pulse second pressure response signal is generated (see FIG. 9C), and the transmission unit 132 transmits the one-pulse second pressure response signal (see FIG. 9D). In the second unit 20, when the signal reception unit 21 receives the one-pulse second pressure response signal transmitted from the first unit 10 (transmission unit 132) (see FIG. 9E), the signal generation unit 22 In synchronization with the reception timing, a second sound signal (representing one short sound (beep)) is generated based on the second pressure response signal (one pulse) (see FIG. 9F). Then, based on the second sound signal, the speaker 24 driven by the output circuit 23 emits a second sound consisting of one short sound (beep) (see FIG. 9G).

  As described above, the first two intermittent short sounds and the second short sound are alternately emitted from the second unit 20 while the user is walking. It is done. The user is grounded at the buttocks according to the timings of the first sound and the second sound that are alternately emitted from the second unit 20 ((a): first step in FIG. 1), the timing at which the thumb is kicked ((C) in FIG. 1: 3rd step) and the timing between them ((b) in FIG. 1: 2nd step) can be confirmed. For example, if the first sound (two short tones) is not emitted, the user can confirm that the buttocks are not sufficiently grounded, and the second sound (one short sound). If (picking) is not issued, the user can recognize that the three-step walking is not performed correctly, such as confirming that the thumb is not kicking sufficiently. As described above, the user performs the training for the three-step walking while confirming whether or not the user is walking according to the three-step walking based on the sounds (first sound and second sound) emitted from the second unit 20. be able to.

  In addition, the user can load the shoe 100 with the heel of the foot due to the difference between the first sound (intermittent two short sounds) and the second sound (one short sound). The timing at which the load is applied to the site E1 and the timing at which the load is applied to the thumb load site E2 of the shoe 100 by the thumb portion of the foot can be clearly distinguished and confirmed.

  Further, since the power supply circuit 12 and the signal wireless transmission unit 13 are housed in separate packages from the first piezoelectric element 11a and the second piezoelectric element 11b, the first pressure response signal and the second pressure response signal can be output. The signal wireless transmission unit 13 (the signal generation unit 131 and the transmission unit 132) that performs such processing is placed in the shoe 100 at a suitable place that is not easily affected by the load from the heel of the foot and the load from the toe of the foot, for example, the insole 102. It can be provided at the site corresponding to the arch.

  In addition, since the first pressure response signal and the second pressure response signal are wirelessly transmitted from the first unit 10 provided in the shoe 100 to the second unit 20 from the first unit 10, the second unit 20 is described above. Thus (see FIG. 8), in addition to the user's arm, it can be freely installed within the possible range of wireless communication by the adopted wireless communication system.
