Abstract:
1. A mechanism for transmitting force in a device for measuring force, in particular for a balance, comprising: a parallel-guiding mechanism comprising a stationary parallelogram leg, a movable parallelogram leg and a pair of parallel-guide members that constrain every movable part of the parallel-guiding mechanism to movement in one of a plurality of parallel planes; a lever mechanism comprising at least one lever; and at least one coupling element for introducing the force into the lever mechanism or for transferring the force therein, each coupling element being stiff in a lengthwise direction thereof but elastically bendable, each coupling element comprising at least one first flexure joint and at least two second flexure joints, each first and second flexure joint having a thin material connection and a pivot axis, each first flexure joint pivot axis being transverse to the plurality of parallel planes and each second flexure joint pivot axis being parallel to the plurality of parallel planes, the second flexure joints being respectively located in an upper and a lower portion of the coupling element to provide the coupling element with mobility transverse to the plurality of parallel planes; wherein the lever mechanism and the at least one coupling element are integrally formed from a block of material.
