ABSTRACT:
The invention relates to a load receiver comprising an upper plate 10 and lower plate 11, and a weighing mechanism located between them.
The weighing mechanism is made of two half-beams 12 and 13 supported on pieces 128 and 138 hinged on one side with respect to the upper plate 10 and on the other side with respect to the lower plate 11. Connected at their center by an elastic strip 14 having a constriction 140, these beams receive a flection related to the load. This flection is transferred by arms 15 and 16 to electrodes 151 and 161 forming a capacitor. By measuring the capacity of the capacitor, the weight of the load is obtained. The invention is of use notably for flat bathroom scales.
