Abstract
A portable scale is provided that includes a fulcrum, a balance beam pivotally mounted on the fulcrum, the balance beam supporting a load pan on one end and including an elongated portion having a measurement strip extending along the elongated portion of the balance beam. The portable scale includes a dynamic weight movable along the elongated portion of the balance beam. The dynamic weight includes a display unit on the elongated portion of the balance beam for detecting the location of the dynamic weight along the measurement strip, for electrically converting the location to a weight measurement, and for displaying the weight measurement. The portable scale may include luminescent material.
Claims35
A portable scale comprising:
- a fulcrum;
- a balance beam pivotally mounted on said fulcrum, said balance beam supporting a load pan on one end and comprising an elongated portion having a measurement strip thereon extending from a first end toward a second, opposite end of said elongated portion of said balance beam, wherein said fulcrum is positioned between said load pan and said first end of said elongated portion;
- and
- a dynamic weight movable along said balance beam from said first end to said second end of said elongated portion of said balance beam, said dynamic weight including a display unit on said elongated portion of said balance beam for detecting said location of said dynamic weight along said measurement strip, for electrically converting the location to a weight measurement, and for displaying said weight measurement.
A portable scale comprising:
- a base;
- a pair of fulcrum posts projecting from said base;
- a balance beam pivotally supportable on said pair of fulcrum posts, said balance beam comprising a load pan support member on one end and an elongated portion having a measurement strip thereon extending from said first end toward a second, opposite end of said elongated portion, said pair of fulcrum posts positioned between said load pan support member and said first end of said elongated portion of said balance beam;
- a load pan pivotally supported by said load pan support member;
- a dynamic weight member movably mounted on said balance beam for movement along said elongated portion, said dynamic weight including a display unit on said elongated portion of said balance beam for detecting said location of said dynamic weight member along said measurement strip, for electrically converting the location to a weight measurement, and for displaying said weight measurement;
- and
- a stationary counter weight attached to said load pan support member;
- wherein said stationary counter weight balances against said dynamic weight member when said dynamic weight is located at a zero position of said measurement strip on said balance beam.
