Patent ID: 7838783

Claim:
A lever mechanism including: (a) at least one lever and a base body; (b) a first lever arm of the at least one lever and a second lever arm of the at least one lever, wherein a load force acting on the first lever arm generates a reaction force on the second lever arm of the at least one lever; (c) an elastically deformable articulation connecting the at least one lever to the base body or an element connected to the base body, the elastically deformable articulation defining a swivel axis of the at least one lever and including two elastically deformable bending areas, each bending area having a respective first end area connected directly to the at least one lever and having a respective second end area connected directly or indirectly to the base body or the element connected to the base body; (d) wherein the geometry of each bending area defines a respective longitudinal extension plane and wherein each bending area is bendable in a direction that is perpendicular to its respective longitudinal extension plane for the generation of a swivel motion of the at least one lever; and (e) wherein the longitudinal extension plane of one of the bending areas converges toward the longitudinal extension plane of the other one of the bending areas so as to enclose an angle that is not equal to zero, and wherein the bending areas are arranged so as to define a virtual swivel axis of the at least one lever, the virtual swivel axis lying beyond the respective first end area of each bending area in the direction toward the at least one lever.
