Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a shoe with a gas tank that naturally supports the foot by injecting air or the like into the gas tank inside the shoe.

[Prior art and its problems] Conventionally, a tank part is provided inside the sole of the shoe, the part that contacts the top of the foot, and around the ankle, and air is injected into the tank part to soften the impact from the sole. So-called pump shoes that provide natural support for the feet are known.

With this type of shoe, if the air pressure injected is too low, it will not be comfortable or cushiony, and it will not be able to provide sufficient support for the ankles, etc. Also, if the air pressure is too high, it will put pressure on the top of the foot, etc. It is not possible to get a comfortable feeling when wearing shoes.

Therefore, it was necessary to adjust the air pressure to be injected so that the user could actually put their feet into the shoe and obtain the cushion strength and fit that suited them.

However, because the air pressure is adjusted by feeling, for example, when trying to increase the air pressure a little, you may end up putting in too much air and need to let out the air, or you may let out too much air and need to re-inject air. As a result, air must be repeatedly injected and exhausted, making it difficult to easily adjust the air pressure to the optimum air pressure desired by the user.

Further, even if the air pressure is adjusted by 100 degrees, the air will sometimes bleed out during use, so it is necessary to repeat the same adjustment work as described above each time.

[Purpose of the invention]

An object of the present invention is to provide a shoe with a gas tank that can be easily adjusted to the gas pressure desired by the user.

[Summary of the Invention] The gist of the present invention is to detect the pressure of the gas injected into the gas tank with a pressure detection means, and when a predetermined switch operation is performed, to store the detected pressure detected by the pressure detection means in a storage means. The pressure stored in the storage means and the injection pressure detected by the detection means are displayed simultaneously when the gas is injected next time.

As shown in Fig. 2, an air tank portion (gas tank) 5 is provided in the part of the inside of the shoe that contacts the instep of the foot, the part of the sole that contacts the back of the foot, and the part that contacts the area around the ankle. By injecting air into this air tank section 5,
It cushions the impact from the sole of the shoe and supports the top of the foot and ankle.

Moreover, as shown in the cross-sectional view of FIG.
An air pump 6 for injecting air into the air tank section 5 and a pressure measuring device 7 for measuring the air pressure in the air tank section 5 are provided. These air pump 6 and pressure measuring device F7 are each connected to the air tank section 5 through an air pipe 8. Air injected from the air pump 6 enters the air tank section 5 through the air pipe 8, and the air in the air tank section 5 is The air enters the pressure measuring device 7 through the air pipe 8 and the air pressure is measured.

Further, an insole 9 is placed above the air tank portion 5.

FIG. 4 is an external view of the pressure measuring device 7, and FIG. 5 is a circuit configuration diagram thereof.

As shown in Fig. 4, the pressure measuring device 7 includes a switch S that is operated when measuring the air pressure, and a switch S that is operated when the pressure adjustment is completed and the current pressure value is stored, or when adjusting the time, the correction digit is selected. A switch S2 is operated to set an arbitrary value to a selected digit when adjusting the time, and a dot matrix display section 11 is used to display measured pressure, memorized pressure, current time, etc. It is provided.

Next, the circuit configuration of the pressure measuring device 7 will be explained with reference to FIG.

In the figure, the CPU 12 is a central processing unit that measures time, measures the air pressure in the air tank section 5, and displays the time and air pressure, and stores the measured current time, measured pressure data, etc. in the RAM 17.

The RAM 17 is provided with various registers as shown in FIG. In the same figure, the 1,000-F register M is
This is a register that indicates the operating mode. For example, "0" indicates the time display mode, and "1" indicates the pressure measurement mode.
is set.

The time register T is a register that stores the current time measured by the CPU 12, and the counter C is a counter that measures the time interval of pressure measurement.

Registers Do and D+ are registers that each store four pressure measurement values and the previous pressure measurement value. The pressure data memory S is a register that stores the pressure value that the user has instructed to import, and stores the pressure value of the air tank section 5 at the end of the pressure adjustment as the target pressure for the next pressure adjustment. do.

The display register A is a register that stores data to be displayed on the tod matrix display section 11, and stores data transferred from the clock register T, pressure data memory S, or the like.

Returning to FIG. 5, the pressure valve 14 is connected to the air pipe 8 described above, and when the pressure valve 14 is opened, the air in the air tank section 5 is supplied to the pressure sensor 15 and the air pressure is measured.

For example, when the switch S is operated to instruct the start of air pressure measurement, the CPU 12 sends an open signal a to the opening/closing drive section 13.
is output to instruct the opening of the pressure valve 14, and at the same time, a pressure sensor 17 and A/D conversion circuit operation signal is output to start pressure measurement. The measured pressure data is then stored in the register Do of the above-mentioned RA, M17.

Further, the buzzer 18 is used to notify whether the air pressure is increasing or decreasing by two types of alarm sounds when adjusting the air pressure.

The oscillator (O5C) 19 is a circuit that generates a clock signal with a constant period, and the generated clock signal is frequency-divided by a frequency dividing circuit 20 and used as a timing signal that serves as a reference for measurement intervals for time measurement and pressure measurement. It is output to the CPU 12.

Next, the operation of the pressure measuring device 7 will be explained with reference to the flowcharts shown in FIGS. 7 to 9 and the display example shown in FIG. 10.

The CPU 12 is normally in the halt state of step 31 in FIG. 7, and each time a 1-second clock signal is applied, the CPU 12 advances to step S2 and determines whether the mode register M is rlJ.

If M=0, it is the time display mode, and the process advances to step S3 to update the current time in the timer register T, and then displays the updated current time in the display process of the next step S4.

Here, the display process in step S4 will be explained with reference to a more detailed flowchart of the display process in FIG.

First, in step S31 of FIG. 9, it is determined whether the value of the mode register M is "0" or not. If it is the time display mode of 0M-0, the process advances to step S32 and the current time data stored in the time register T is displayed. is transferred to display register A, and the current time data is displayed on dot matrix display section 1.

FIG. 10(a) is a diagram showing an example of the display in the time display mode. ' is displayed.

If any switch operation is detected in the halt state of step Sl in FIG. 7, the process proceeds to step S5 and it is determined whether or not the operated switch is the S+ switch.

When the S1 switch is operated, the next step S6
It is determined whether the value of mode register M is "0" or not.

If M=0, it means that the 31 switch is operated in the time display mode and the start of pressure measurement is instructed,
In the next step S7, an open signal a is output to open the pressure valve 14, and at the same time, in step S8, the sensor section 15 and the A/
The supply of power to the D conversion circuit 16 is started. Also, since the time display mode has been switched to the pressure measurement mode at this time, rl is set in the mode register M in the next step S9.

When "1" is set in the mode register M, the determination of whether the mode register M is "1" in step S2, which is performed every time a 1-second interval clock signal is applied, becomes YES, so the next step S10 The counter C is incremented by "1" each time a clock signal is added. Further, in step 311, it is determined whether the counter C is "5" or not, and if C=5, that is, if 5 seconds have elapsed, the process advances to step S12 and pressure measurement processing is executed.

Here, the pressure measurement process in step S12 will be explained with reference to the flowchart in FIG.

If the determination in step 311 in FIG. 7 is YES and the pressure measurement timing is set to be every 5 seconds, the pressure measurement process in FIG. 8 is executed. First, in step 521 of FIG.
The previous pressure data stored in register Do is transferred to register D+.

Next, in step S22, the pressure data measured this time is stored in the register Do.

Furthermore, in step s23, the pressure data of the register DO and the pressure data of the register D+ are compared, and Do<D
If the value is +, that is, if the pressure in the air tank section 5 is decreasing, the process advances to step S24 and alarm I processing is executed.

Further, if D0≧D1 in the determination in step S23, that is, if the pressure in the air tank section 5 is increasing,
Proceeding to step 325, the alarm (2) process is executed and an alarm sound different from that in the alarm (r) process is sounded.

Through these processes, in the process of adjusting the pressure in the air tank section 5, different alarm sounds are reported when the pressure is increased by injecting air and when the pressure is decreased by exhausting the air. Since the alarm sounds, you can check whether the air pressure is increasing or decreasing.

Returning to FIG. 7, the one operated in step S5 is S.
, if it is not a switch, the process proceeds to step 313 and it is determined whether or not the Sz switch has been operated.

If it is the 32 switch that was operated, proceed to the next step 5.
At step 14, it is determined whether the value of mode register M is "1" or not.

When the 32 switch is operated in the M-1's pressure measurement mode, the air pressure can be adjusted to the optimum level for the cushion strength and fit desired by the user, and the 82 switch is activated to memorize the pressure at that time. The pressure value stored in the register Do is transferred to the pressure data memory S at step S15. after that,
Display processing in step S4 is executed.

In the pressure measurement mode where M=1, the determination as to whether the mode register M is "0" in step 331 of the display process in FIG. 9 is NO, and the process proceeds to step S33. In step S33, the current measured pressure data stored in the register Do and the optimum pressure stored in the pressure data memo + JS are transferred to the display register A, and these pressure data are displayed on the dot matrix display section 11. be done.

Figure 10 (℃) shows an example of the display at this time,
The pressure value "1°76 kg" stored in the pressure data memory S is displayed in the upper part of the dot matrix display section 11, and the measured pressure at that time "r134 kg" is displayed in the lower part.
is displayed.

Therefore, if the pressure at which the user's desired cushioning and fit are obtained by adjusting the air pressure is stored in the pressure data memory S, the next time air is injected, the current injection pressure, e.g. , 34 kg'' and the optimum pressure stored in the pressure data memory S, e.g. rl,
76) cg" are displayed, the injection pressure can be easily adjusted to the pressure desired by the user while looking at these displays. As a result, when the air is released like before,
There is no need to delicately adjust the air pressure in the air tank section 5 each time by feeling with the feet, and once the air pressure is adjusted by -degrees, it is easy to adjust the air pressure to provide the cushion strength and fit that the user desires. can be adjusted to

After completing the adjustment of the air pressure as described above and storing the adjusted pressure value in the pressure data memory S, the S
1 switch is operated, step 31 of step S5 in FIG.
The determination as to whether or not the switch has been operated is YES, and the determination as to whether the value of the mode register M in step S6 is "0" is NO, and the process proceeds to step 516, where the closing of the pressure valve 14 is instructed.

Furthermore, in the next step S17, the sensor section 15 and the A/D
The voltage supply to the conversion circuit 116 is stopped, and the pressure measurement ends. After that, in step S18, registers Da and D
+ is cleared, and mode register M is further set to "0" to switch to time display mode.

On the other hand, when the 32 key is operated in the time display mode, it is determined whether or not the 32 switch is operated in step 513 of FIG. becomes No, and step S
Proceed to step 19 to execute correction digit selection processing.

Also, if it was the 33 switch that was operated at this time,
If the determination in step S13 is NO, the process advances to step S20 and a correction process is executed.

That is, in the time display mode, operate the S2 and S3 switches to select each digit of the date, hours, minutes, and seconds.
You can set any numerical value to the selected digit and adjust it to the desired time.

Further, the configuration of the air tank section 5 and the tubes connecting them, or the locations of the air pump and pressure measuring device, etc., are not limited to the above embodiments, and other configurations may be used.

Furthermore, the air pump is not built into the shoe, but instead has an injection valve.
Gas may be injected from an external air pump, gas cylinder, etc.

Further, the measured pressure data and the stored optimum pressure may be displayed in analog form.

The present invention can be applied to various shoes such as leather shoes, sports shoes, mountain climbing shoes, and golf shoes.

〔Effect of the invention〕

According to the present invention, if the gas pressure is adjusted to provide the desired cushioning properties and fit, and the pressure at that time is memorized, from then on the gas pressure will match the memorized optimal pressure. Since the pressure of the gas injected into the cushion can be adjusted easily, the pressure can be adjusted in a short time to a level that provides the cushion strength and fit desired by the user.
