摘要:
A lever mechanism, particularly for a scale receiver of a scale that works on the principle of electromagnetic force compensation includes at least one lever which is connected to a stationary base body or an element connected to the base body. The at least one lever arm is connected to the base body or the element connected to the base body via an elastically deformable articulation which defines a swivel axis of the at least one lever. A load force (FL), which corresponds to the weight force (FG) or is derived therefrom, acts on a first lever arm of the at least one lever and generates on a second lever arm of the at least one lever a reaction three (FR). The elastically deformable articulation comprises two thin, elastically deformable bending areas, which connect the lever to the base body or to the element connected to the base body. Each bending area is bendable in a direction that is perpendicular to a longitudinal extension plane defined by the geometry of the respective bending area, for the generation of a swivel motion of the at least one lever. The longitudinal extension planes of the bending areas enclose an angle (α) that is not equal to zero, and a virtual swivel axis (D) of the at least one lever is defined by the two elastically deformable bending areas.
