Abstract
A method and apparatus for indicating force, weight in particular, is done mechanically. The method has the steps of engaging the force with a base plate, bending the plate with force, rotating an indicator plate with respect to the base plate and about an obtuse axis hinge movably adjoining the plate, and measuring the rotation and converting it to an expression of force. The Apparatus has a base plate, an indicator plate, a hinge movably adjoining the two plates, an obtuse hinge axis, and structure to measure and interpret rotation of the indicator plate about the obtuse hinge axis as the base plate is bent by a force such as weight. A specific embodiment of the weight scale is provided for a fishing rod, for a fish scale, and for a pail scale.
Claims35
A method of indicating force, comprising the steps of
- a) engaging the force with a generally planar base plate, said base plate having a hinge having a curved hinge axis;
- b) bending the plate and the curved hinge axis;
- c) rotating an indicator about the curved hinge axis during bending of the plate;
- d) measuring rotation of the indicator;
- and
- e) converting the measured rotation into an expression of force.
Apparatus for indicating force, comprising
- a) a base plate;
- b) an indicator plate;
- c) a hinge connecting said plates movably to each other, said hinge having a curved hinge axis;
- d) means on said base plate for engaging two forces;
- e) means on said indicator plate for indicating movement of said indicator plate with respect to said base plate, as a measure of the forces engaged by said base plate.
A weight scale comprising
- a) an elongate base plate;
- b) an indicator plate having an output pointer;
- c) a hinge connecting said base plate and said indicator plate movably to each other, said hinge having a hinge axis which is curved;
- d) a graduated scale on a scale member in proximity to said pointer for prodding a visual quantification of the pointer position, such position being indicative of a measured weight;
- e) handle means connected to said base plate for holding said base plate;
- and
- f) weight connecting means for connecting said base plate to a load to be weighted.
A fishing rod weighing scale, comprising
- a) an elongate base plate;
- b) an indicator plate having an output pointer;
- c) a hinge connecting said base plate and said indicator plate movably to each other, said hinge having an axis which is curved;
- d) a graduated scale on a scale member in proximity to said pointer for enabling visual reading of the pointer with respect to the graduated scale and;
- e) means for connecting said base plate to the shaft of a fishing rod.
