Abstract

A shoe including a shoe body having an outsold and an upper fastened to the outsole; an insole formed as an air bag filled with air and mounted within the outsole; a pressure inductor connected to the insole to detect the pressure applied to the insole; a circuit board mounted in the insole and consisting of a pressure converter and a microprocessor, the pressure converter converting the pressure detected by the pressure inductor into a frequency signal to be processed by the microprocessor so that the microprocessor obtains a value corresponding to the pressure applied to the insole; and a liquid crystal display connected to the microprocessor to display the value obtained by the microprocessor.

Claims

1. A shoe comprising:

a shoe body having an outsole defining a receiving chamber, and an upper fastened to said outsole;

an insole formed as an air bag filled with air;

a pressure inductor connected to said insole to detect the pressure of the air imposed on the pressure inductor in response to pressure applied to said insole;

a circuit board mounted in the receiving chamber of said insole, comprising a pressure converter and a microprocessor, said pressure converter converting the pressure detected by said pressure inductor into a frequency signal having a variable frequency representative of the detected pressure, the frequency signal processed by said microprocessor so that said microprocessor provides a value corresponding to the pressure of the air inside the insole; and

a liquid crystal display connected to said microprocessor to display the value calculated by said microprocessor.

2. The shoe of claim 1, wherein said liquid crystal display is mounted on the upper of said shoe body.

3. The shoe of claim 2, wherein said insole has an air outlet sealed with a diaphragm;

said pressure inductor is coupled with a connector, said connector has a longitudinal through hole and a pointed front projection, said pointed front projection extending through the diaphragm of said air outlet, permitting air to flow from said insole to said pressure inductor.

4. The shoe of claim 1, wherein said microprocessor is connected to a function key, and has a display mode changeable with the state of said function key.

5. The shoe of claim 4, wherein said display mode is a step number display mode which shows the number of steps applied by the user to said insole and measured by said microprocessor by adding one to the reading when the pressure measured surpasses a predetermined value and then drops below it.

6. The shoe of claim 4, wherein said display mode is a maximum weight display mode which shows through said liquid crystal display the maximum value obtained by said microprocessor.

7. The shoe of claim 1, wherein said insole comprises a front air chamber, a rear air chamber, and an intermediate air chamber communicating between said front air chamber and said rear air chamber.

8. The shoe of claim 7, wherein said intermediate air chamber has an air outlet connected to said pressure inductor.

9. The shoe of claim 1, wherein said insole is secured to the outsole by an anchoring means.

10. The shoe of claim 9, wherein said anchoring means include partition ribs formed integral with the outsole.

11. The shoe of claim 1 further comprising a connector coupled to the pressure inductor, and wherein the insole includes an air outlet and a diaphragm sealed within the air outlet, the connector being tightly engaged with the air outlet.
