The invention relates to a lever mechanism, particularly for a scale receiver of a scale that works on the principle of electromagnetic force compensation, with at least one lever (23), which is connected to a stationary base body (3) or an element connected to the latter, where the at least one lever arm is connected via an elastically deformable articulation (28), which defines a swivel axis of the at least one lever (23), to the base body (3) or to the element connected to it, and where, on a first lever arm of the at least one lever, a load force (FL) acts, which corresponds to the weight force (FG) or is derived therefrom, and which generates on a second lever arm of the at least one lever a reaction force (FR). According to the invention, the elastically deformable articulation (28) comprises two thin, elastically deformable bending areas (29), which connect the lever indirectly or directly to the base body (3) or to the element connected to it, where each bending area (29) is bendable in a direction that is vertical to a longitudinal extension plane defined by the geometry of the bending area (29), for the generation of a swivel motion of the at least one lever (23), where the longitudinal extension planes of the bending areas (29) enclose an angle (α) that is not equal to zero, and where a virtual swivel axis (D) of the at least one lever (29) is defined by the two elastically deformable bending areas (29).
Lever mechanism, particularly for a scale receiver of a scale that works on the principle of electromagnetic force compensation,
Lever mechanism according to one of the preceding claims, characterized in that the intersection line of the two longitudinal extension planes of the two bending areas (29) forms the virtual swivel axis (D) of the at least one lever.
Lever mechanism according to one of the preceding claims, characterized in that the plane, which bisects the angle (α) enclosed by the longitudinal extension planes, and which also runs through the virtual swivel axis (D), runs perpendicularly to the direction of the load force (FL).
Lever mechanism according to one of the preceding claims, characterized in that the load force (FL) is transmitted via a thin, elastically deformable bending area (27) to the lever (23), where the bending area (27) is designed such that its longitudinal extension plane runs parallel to the virtual swivel axis (D).
Lever mechanism according to one of the preceding claims, characterized in that the reaction force (FR) is transmitted via a thin, elastically deformable bending area to the lever (23), where the bending area is designed such that its longitudinal extension plane, which contains the direction of the force transmission, runs parallel to the virtual swivel axis (D).
Lever mechanism according to one of the preceding claims, characterized in that one or both bending areas (29) of the elastically deformable articulation (28) are connected via a coupling element (31) to the base body (3) or the element connected to it.
Scale receiver, particularly for a scale that works on the principle of electromagnetic force compensation, with a lever mechanism according to one of the preceding claims, which magnifies or reduces the weight force (FG) to be determined.
Positioning device, for example, for optical components, with a lever mechanism according to one of the preceding claims, which converts the movement of an actor into a movement of a holder device for the element to be positioned.
