Integrally formed flexure pivot for a force-measuring device, and force-transfer mechanism with the flexure pivot

Force-transfer mechanism for a force-measuring device, with a stationary portion, and with a lever arrangement comprising:

• at least one reduction lever serving to transmit a force to a measuring transducer;
• at least one coupling element serving to introduce an input force into the lever arrangement, said coupling element being stiff against lengthwise deformation but flexible with regard to bending and having at least one thin material connection;
• and
• a flexible fulcrum pivot for supporting the at least one lever on the stationary portion and/or on a preceding lever, the flexible fulcrum pivot comprising:
• a thin material connection, wherein the thin material connection comprises at least one thin material connection zone, that is delimited by concave-shaped surfaces facing material-free spaces, wherein at least one of the material-free spaces delimiting the thin material connection zone has a shape that creates a constriction of the thin material connection zone.

Flexure pivot in the form of a thin material connection by which solid material portions are flexibly connected, for use in a force-transfer mechanism with a stationary portion and with a lever arrangement comprising:

• at least one reduction lever serving to transmit a force to a measuring transducer;
• at least one coupling element serving to introduce an input force into the lever arrangement, said coupling element being stiff against lengthwise deformation but flexible with regard to bending and having at least one thin material connection:
• and,
• a flexible fulcrum pivot for supporting the at least one lever on the stationary portion and/or on a preceding lever;
• wherein
• the at least one coupling element comprises a thin material connection formed by adjacent material-free spaces and including at least one thin material connection zone delimited by concave-shaped surfaces facing material-free spaces, wherein at least one of the material-free spaces delimiting the thin material connection zone has a shape that creates a constriction of the thin material connection zone.
