Abstract

PURPOSE:To provide shoes capable of counting accurately the number of steps even in walking and running. CONSTITUTION:When a foot touches down the ground, pressure in a gas tank reaches the peak. When the foot is separated from the ground, the pressure in the gas tank is abruptly lowered and the weight of one's body is not temporarily applied to the gas tank. In an embodiment, when measured pressure data are lowered lower comparative pressure data stored in a comparative pressure register D1 of an RAM 18, it is counted as one step of the number of steps. Namely, a controller section 14 inputs the comparative pressure data stored in the comparative pressure register D1 to an amplifying-voltage comparing section 16 which compares the measured pressure data from a sensor section 15 with the comparative pressure data to judge whether or not the measured pressure data is lowered lower than the comparative pressure data. When the measured pressure data is lowered lower than the comparative pressure data, the amplifying-voltage comparing section 16 outputs a detecting signal to the controller section 14 which advances a counter C by +1 to count the number of steps.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe in which a gas tank is provided inside the shoe to support the foot.

[0002]

2. Description of the Related Art Recently, shoes having a gas tank whose pressure can be adjusted by an air pump have been developed. This shoe is called a pump shoe, and is provided with a gas tank at the shoe bottom, ankles, etc., and air is injected into this gas tank to protect the foot from impact.

However, in the conventional pump shoes, since the pressure of the gas tank provided inside the shoes is adjusted by the user's manual control, it is difficult to determine the pressure and it is difficult to adjust the air pressure. Therefore, the present applicant has devised and filed a pump shoe that is equipped with a pressure gauge for measuring the pressure of the gas tank so that the air pressure can be easily adjusted and the movement result such as the number of steps data can be stored. 2-
291525).

[0004]

By the way, in the shoe of the prior application, the number of steps is counted when the pressure in the gas tank exceeds 1.5 times the set pressure due to the stepping during walking.
In this case, since many pressure peaks appear due to depression, the pressure detection is stopped for a predetermined time (0.5 seconds) thereafter to prevent multiple counting. As described above, in the shoe of the prior application, the circuit is complicated because the detection stopping means is provided. Moreover, since the appearance level of the pressure level and the pressure peak at the time of stepping are different between when walking and when slowly running, it is easy to cause a malfunction by detecting that a predetermined multiple of the set pressure is exceeded. There was a flaw.

The present invention has been made to solve the above problems, and an object thereof is to provide a shoe which can accurately count the number of steps even when walking or running.

[0006]

In order to solve the above-mentioned problems, the present invention provides a gas tank provided inside a cover,
Pressure detecting means for detecting the pressure in the gas tank, counting means for counting the number of times the pressure in the gas tank drops below a preset pressure value set by the pressure detecting means, and counting by the counting means A display unit for displaying step count data based on the content.

The pressure measuring device 10 has a monitor mode “M = 0” and a pedometer mode “M = 1”, measures the pressure in the gas tanks 6 and 7 in the monitor mode, and in the pedometer mode. The number of steps is measured by the pressure change in 6 and 7.

In the figure, the control unit (CPU) 14 is R
It is a central processing unit that performs various processes such as pressure measurement in the gas tanks 6 and 7 and data storage based on a microprogram stored in advance in the OM 17. The sensor unit 15 is composed of a pressure sensor, detects the pressure in the gas tanks 6 and 7 via the air pipe 13, and outputs a detection voltage signal corresponding to the pressure to the amplification / voltage comparison unit 16.

The amplification / voltage comparison unit 16 amplifies the measurement pressure signal output from the sensor unit 15 and further performs A / D (analog / digital) conversion to output to the control unit 14 and output from the control unit 14. The comparison pressure D ₁ thus obtained is compared with the pressure measured by the sensor section 15. The sensor unit 15

The driver 22 is the control unit 14
A display drive signal is output to the display unit 12 configured by an LCD (liquid crystal display element) based on the display data output from the display unit 12.

Next, the operation of the above embodiment will be described with reference to FIGS. 8 is a flow chart showing the entire operation, FIG. 9 is a flow chart showing the operation when the K2 key is operated, FIG. 10 is a flow chart showing the procedure of use, and FIG. 11 is a gas tank 6 according to the procedure of use of FIG.
7 is a diagram showing a change in pressure inside 7. FIG.

The use procedure will be described with reference to FIG. First, the user wears shoes (step C1) and attaches an air pump to a valve (not shown) communicated with the gas tanks 6 and 7 (step C2). Next, the K1 key is operated to turn on the power source of the pressure measuring device 10, and the K3 key is operated to set the content of the mode register M to "M = 0" (step C3). As a result, the process shown in FIG. 8 is started, and the pressures of the gas tanks 6 and 7 are measured every 3 seconds and displayed on the display unit 12. Then, while observing the pressure data displayed on the display unit 12, air is injected into the gas tanks 6, 7 by the air pump to adjust the air in the gas tanks 6, 7 (step C4).

When the power is turned on, the processing shown in the flowchart of FIG. 8 is started. First, in step A1, "M
= 0 ", that is, whether the content of the mode register M is" 0 "or not. If YES in step A1, the process proceeds to step A2, and if NO in step A1, the process proceeds to step A5. Now, by default, "M = 0", so step A
From 1 to step A2.

In step A2, the timer T is incremented by 1 and the time is counted. Next, in step A3, it is determined whether or not "T = 3 seconds", that is, the content of the timer T is a value corresponding to 3 seconds. If YES in step A3, the process proceeds to step A4, and if NO in step A3, the process proceeds to step A7.

If not "T = 3 seconds", the process proceeds from step A3 to step A7, and the display process according to the contents of the mode register M is executed. That is, the measured pressure data stored in the measured pressure register D ₀ is displayed on the display unit 12 in the monitor mode of “M = 0”, and the step count data stored in the counter C is displayed in the pedometer mode of “M = 1”. Display 12
Displayed in. After execution of step A7, the process returns to step A1, and steps A1 to A3 and A7 are repeatedly executed as described above.

Then, when the time count of the timer T advances and becomes "T = 3 seconds", YES is determined in the step A3 and the process advances to the step A4. In step A4, the pressure in the gas tanks 6 and 7 is measured by the sensor unit 15, and the measured pressure data is stored in the measured pressure register D ₀ . That is,
The control unit 14 outputs an operation signal a to the sensor unit 15 and the amplification / voltage comparison unit 16 every 3 seconds to operate them.
As a result, the sensor voltage output from the sensor unit 15 is input to the amplification / voltage comparison unit 16, converted into a digital signal, and input to the control unit 14. The control unit 14
The measured value input from the voltage comparison unit 16 is stored in the measured pressure register D ₀ of the RAM 18. Also, the timer T is cleared and a new time count is started. From step A4 to step A7, the display processing is performed in the same manner as described above, and the measured pressure data stored in the measured pressure register D ₀ is displayed on the display unit 12.

By the air injection, the pressure in the gas tanks 6 and 7 gradually rises as described as "air injection" in FIG. 11, so the air injection is stopped when the optimum support state is reached. Next, when the foot is lifted and the shoe is separated from the ground (step C5), the weight of the user is not applied to the shoe, so that the pressure in the gas tanks 6 and 7 is significantly increased as shown in A of FIG. Decrease. When the decrease is stable at B in FIG. 11,
When the K2 key is operated, the pressure in the gas tanks 6 and 7 is measured, and the comparison pressure data is set in the comparison pressure register D ₁ (step C6).

That is, the operation shown in the flowchart of FIG. 9 is started by operating the K2 key. First, step B
At 1, it is determined whether or not “M = 0”. If YES in step B1, the process proceeds to step B2, and if NO in step B1, the process proceeds to step B3. Since "M = 0" has been set by the execution of step C3, it is determined to be YES and the process proceeds to step B2.

In step B2, the gas tank 6,
The pressure inside 7 is measured by the sensor unit 15, and the pressure data obtained by multiplying the measured pressure data by 1.2 is compared to the comparison pressure register D ₁
Remember. That is, the control unit 14 outputs the operation signal a to the sensor unit 15 and the amplification / voltage comparison unit 16 to operate them. As a result, the sensor voltage output from the sensor unit 15 is input to the amplification / voltage comparison unit 16, converted into a digital signal, and input to the control unit 14. Control unit 14
Is the measured value input from the amplification / voltage comparison unit 16.
The doubled value is stored in the comparison pressure register D ₁ . By executing step B2, the processing in FIG. 9 ends. As a result, the comparative pressure data serving as the reference for detecting the number of steps is stored in the comparative pressure register D ₁ .

Returning to FIG. 10, the contents of the mode register M are inverted from "0" to "1" by operating the K3 key again to set "M = 1" (step C7). Next, operate the K2 key again to change the contents of the flag register F to "F =
1 ”(step C8).

That is, by operating the K2 key, the processing shown in the flowchart of FIG. 9 is started in the same manner as described above. First, in step B1, it is determined whether or not “M = 0”. Since “M = 1” is currently determined, it is determined to be NO and step B3.
Proceed to. In step B3, it is determined whether or not "F = 0". If YES in step B3, step B4
If NO, proceed to step B6. Now, "F
Since it is "= 0", it is determined to be YES and the process proceeds to step B4. If the K2 key is operated when "F = 1", the process proceeds from step B3 to step B6, and "0" is written in the flag register F.

In step B4, the comparison pressure register D ₁
The comparative pressure data stored in is output to the display unit 12 and the counter C is cleared. In the following step B5, "1" is written in the flag register F and "F =
1 ”, and the processing of FIG. 9 ends.

As a result, preparation is completed, and when walking is started, step counting is started (step C).
9). At this time, the processing shown in the flowchart of FIG. 8 is executed. Since "M = 1" is determined in step A1, NO is determined and the process proceeds to step A5. At step A5, “F =
It is determined whether or not it is "1", and since "F = 1" now, it becomes YES and the process proceeds to step A6.

In step A6, a step count detection process is executed. As shown in FIG. 11, when the foot lands on the ground, the pressure in the gas tanks 6 and 7 reaches a peak. Then, when the foot is separated from the ground, the pressure in the gas tanks 6 and 7 drops rapidly, and the weight is temporarily not applied. In this embodiment, when the measured pressure data drops below the comparative pressure data (D ₁ level in FIG. 11) stored in the comparative pressure register D ₁ , this is taken as one step and the number of steps is counted.

That is, the control unit 14 controls the comparison pressure register D ₁
The comparison pressure data stored in is input to the amplification / voltage comparison unit 16. The amplification / voltage comparison unit 16 compares the measured pressure data output from the sensor unit 15 with the comparative pressure data, and determines whether the measured pressure data drops below the comparative pressure data (D ₁ level in FIG. 11). To judge.

When the measured pressure data drops below the D ₁ level), the amplification / voltage comparison unit 16 causes the control unit 14 to
A detection signal is output to. As a result, the control unit 14
Counts the number of steps by incrementing the counter C by 1. When it is desired to obtain the number of steps on the left and right, the number may be set to +2 instead of +1. Then, from step A6 to step A
Proceed to 7. In step A7, since “M = 1”, the step count data stored in the counter C is displayed on the display unit 12. After execution of step A7, the process returns to step A1.

Thereafter, as in the above, steps A1 and A5
A7 is repeatedly executed and the counter C counts the number of steps.

Although air is injected into the gas tanks 6 and 7 in the above-described embodiment, the gas to be injected is not limited to air, and a gas other than air such as carbon dioxide gas or a liquid may be used. Further, the present invention can be applied to various shoes such as athletic shoes, leather shoes, ski shoes, golf shoes, and various boots other than ordinary shoes.
