  • Patent number: 7345249
    Abstract: In a force-transmitting mechanism (1, 101) with a parallel-guiding mechanism having a stationary (2) and a movable (4) parallelogram leg (2), with a lever mechanism having at least one lever (6), and with at least one coupling element (5, 105) that introduces a force into the lever mechanism or transfers the force within the lever mechanism, wherein the coupling element is stiff in its lengthwise direction but bends elastically. The coupling element has at least one first flexure joint (8) with a thin material connection and it is movable in the parallelogram plane. The lever mechanism and each coupling element (5, 105) are integral parts of a material block. Each coupling element (5, 105) also has at least two second flexure joints (16, 116) with thin material connections whose flexibility is in the direction transverse to the bending of the first flexure joint (8).

  • Patent number: 5923000
    Abstract: A shock protection device for a force measuring apparatus, particularly a balance, which includes a material block with a stationary parallelogram side member, a deflectable parallelogram side member serving for receiving the force to be measured, two guide members which are bending-elastic in the plane of the parallelogram and which connect the two parallelogram side members, and at least one lever which is connected through a coupling member to the deflectable parallelogram side member. The shock protection device includes a safety bolt inserted into a bore extending at least partially through the force measuring apparatus, wherein the safety bolt is connected without play to one of the components forming the force measuring apparatus, while the safety bolt has radial play relative to the remaining components through which the bolt extends.
