ABSTRACT:
PCT No. PCT/CH78/00011 Sec. 371 Date Apr. 5, 1979 Sec. 102(e) Date Mar. 12, 1979 PCT Filed Aug. 4, 1978 PCT Pub. No. WO 79/00136 PCT Pub. Date Mar. 22, 1979. A scale, which is particularly intended for weighing humans, comprises a pedestal and a table. The pedestal is provided with upwardly extending and the table with downwardly extending holders, which are arranged at the region of the table edge and essentially uniformly distributed over the table circumference. In each case there alternately follows a holder at the pedestal a holder of the table. The holders are provided at their free ends with a notch which forms a holding location for an electrical conductor. The conductor consists of an electrically elongatable wire and extends in a zig-zag configuration from one holder to the other. Both ends of the conductor are connected with an electronic measuring unit, which contains means for detecting the electrical resistance of the conductor. The conductor thus carries the table and at the same time serves as a measuring transducer, in order to convert the weight load of the table into an electrical signal.
