A force-reduction mechanism for a force-measuring device is made of a monolithic material block ( ) and has a stationary support ( ), a plurality of levers ( ), and coupling elements ( ) connecting the levers. The fulcrum ( ) of at least one lever ( ) is movable in relation to the stationary support ( ). A movable fulcrum ( ) can, e.g., be located on a preceding lever ( ), so that the fulcrum ( ) shares the motion of the preceding lever ( ). The concept of a movable fulcrum allows a more space-efficient design of the mechanism.

Force-reduction mechanism for a force-measuring device

In a weighing cell a load receiver is constrained in a mode of planar translatory motion in relation to a stationary part (,). The stationary part (,), configured in the shape of a solid H-profile, has two side plates (,) to which the guide links of a parallelogram mechanism are attached. A base plate (,) connects the side plates (,) and supports the parts, that are required for transmitting a force to be measured from the load receiver to a measuring cell. The force-transmitting parts can be configured either as a monolithic material block or as individually assembled components. (FIG. 1)
