Abstract

A travel sized, compact apparatus which measures the body weight of an individual, comprising a platform small enough to support only one foot of the individual to be weighed; a conversion means for converting the mechanical response signals from the weight of the individual to a display for presenting the measured body weight of the individual. The apparatus is designed to continue to display the individuals'"'"' weight after disengaging the device, until a few seconds has lapsed or, after or the individual causes the display to be reset.

Claims

1. A compact weight scale constructed to hang from a doorframe lintel while also supporting, weighing and indicating the proper weight of an individual comprising:

A case with an internal cavity for housing a load cell, situated to receive the force produced when said case pulled downward due to the weight of an individual, and outputting an electric signal corresponding to the weight of an individual;

A digital display coupled to said load cell for receiving said electric signal and producing a digital display indicating the weight of an individual;

A doorway lintel hook attached to the top portion of a load cell located inside said case for vertical support of said scale;

A support structure for supporting the weight of an individual attached to the bottom portion of said case.

2. The weight scale of claim 1 wherein said support structure is a foot platform and foot support providing sufficient space and support for one foot of an individual

3. A compact weight scale with a digital display for determining and indicating the weight of a person comprising:

A first platform means for supporting one foot of a person, obtaining a coarse measurement of the person'"'"'s weight and outputting a signal corresponding to said measurement;

A second platform means coupled to said first platform means for supporting one foot of a person, receiving said signal from said first platform, obtaining a fine measurement of a person'"'"'s weight and outputting a combined signal corresponding accurately to a person'"'"'s weight;

A digital display for receiving said combined signal and displaying the person'"'"'s weight.

4. A compact weight scale according to claim 3 wherein said first platform comprises graduated measurements of at least 10 pound divisions or equivalents thereof.

5. A compact weight scale with an analogue display for supporting one foot of a person, while also determining and displaying the person'"'"'s weight comprising:

A foot platform for supporting one foot of a person comprising a top and bottom plate with a jack sandwiched between at a central location to enable separation of plates;

Electric contacts attached to the interior surface of said top and bottom plates such that they are in contact when said top and bottom plates are in contact and separated when said plates are separated;

A hand pump to enable pumping of hydraulic fluid into said jack thereby separating said contacts;

A solenoid to enable blocking of hydraulic fluid when said contacts are separated;

A scale gauge attached to said hand pump for displaying the weight of an individual.

6. The weight scale of claim 5 wherein said platform can provide a larger surface area for supporting objects larger than a foot.
