ABSTRACT:
Single-piece force-reducing devices for force-measuring apparatuses include levers (18, 25) for reducing the force, and coupling members (17, 21) for transmitting the force, which are formed by no-material portions in one single solid block (1). However, deflection of the levers (18, 25) and, in particular, displacement of their fulcrums (14, 26) leads to incorrect measuring results, so that it is an objective to achieve a very high rigidity of the system under load. In order to achieve such very high rigidity, while the overall size of the system is kept small, the invention provides no-material portions (4, 5, 19, etc.) which make it possible to remove only a minimum of material, resulting in a favorable increase in thickness of the highest-loaded parts, (FIG. 1 ).
