Abstract
A parallel-guiding mechanism (120) has a movable parallel leg (121), a stationary parallel leg (122), a first parallel-guiding member (123) and a second parallel-guiding member (124). The parallel legs and the parallel-guiding members are connected to each other by flexure pivots, in the form of narrow material connections. There is at least one adjustment zone (135). An adjustment flexure fulcrum (136) is arranged between a flexure pivot (131) and a parallel leg. The adjustment zone is connected to the first lever end (138) of an adjustment lever (137). The adjustment flexure fulcrum forms the lever fulcrum (146) of the adjustment lever, which has an elastic domain with a section modulus that is smaller than a section modulus of the adjustment flexure fulcrum.
