Abstract:
1. A parallel-guiding mechanism comprising: a movable parallel leg; a stationary parallel leg; two parallel guides, connecting the respective parallel legs and constraining the movable parallel leg in guided vertical movement; elastic flexure pivots or elastic parallel guide sections, formed or arranged in the areas of connection between the parallel guides and the parallel legs; at least one adjustment domain, formed by at least one incision provided at least one of the respective parallel legs; and at least one deformation zone, delimited by the at least one incision, each deformation zone being plastically deformable in a controlled manner by applying an adjustment force or torque which causes a controlled permanent change in the position of the parallel guides relative to each other, the controlled permanent change serving to correct a corner load error of the parallel-guiding mechanism, such that each deformation zone is stress-free at least when no load is applied to the movable parallel leg.
