Abstract

A shoe containing two scales entirely housed within its sole, which scales may be deployed downward so that they project beneath the shoe'"'"'s sole—making the scales thereby able to accurately weigh the wearer as the wearer briefly stands only upon the thus deployed scales. After such a weight determination, the scales may be retracted—once again housed entirely within the shoe'"'"'s sole—making the shoe ready to be worn and used in any and all conventional manners.

Claims

1. A shoe with at least one scale retractably mounted in the sole comprising:

a shoe with a permanently attached sole having a bottom ground engaging surface;

a scale permanently attached to the sole but selectively movable between a retracted position and a deployed position;

a cavity in the sole to receive the scale in the retracted position;

a lower set of locks to hold the scale in the retracted position;

an upper set of locks to hold the scale in the deployed position wherein it extends partly below the bottom surface;

bias means to urge the scale in the direction of the deployed position;

a device for selectively activating the lower and upper sets of locks; and

a display operatively connected to the scale to produce a visual indication of the weight of the wearer of the shoe.

2. A shoe as described in claim 1 wherein the scale includes a strain gage.

3. A shoe as described in claim 1 further including a microprocessor connected between the scale and the display.

4. A shoe as described in claim 1 further including a radio-frequency telemetry device electronically connected for use in the remote display of weight data produced by the scale.

5. A shoe as described in claim 4 further including a microprocessor connected between the scale and the radio-frequency telemetry device.

6. A shoe as described in claim 1 further including a sound and/or speech-simulation device electronically connected to announce weight data produced by the scale.

7. A shoe as described in claim 6 further including a microprocessor connected between the scale and the sound and/or speech-simulation device.

8. A shoe as described in claim 1 further including electromagnets to activate said locks.

9. A weight-measuring shoe comprising:

a shoe with a permanently attached sole;

a scale mounted within the sole and moveable between a retracted position and a deployed position;

a structural mechanism for selectively moving the scale between the retracted position and the deployed position; and

electronic circuitry connected to the scale for producing a reading of the weight of the person wearing the shoe.

10. A shoe as described in claim 9 further including an information-display device, affixed to the shoe and operatively connected to the scale by means of the electronic circuit, for displaying weight data derived when the scale is in the deployed position.

11. A shoe as described in claim 9 further including a radio-frequency telemetry device, operatively connected to the scale by means of the electronic circuit, for use in the remote display of weight data derived when the scale is in the deployed position.

12. A shoe as described in claim 9 further including a sound and/or speech-simulation device, operatively connected to the scale by means of the electronic circuit, for announcing weight data derived when the scale is in the deployed position.
