Patent ID: 7829802

Claim:
A parallel-guiding mechanism, comprising: a stationary parallel leg, with an upper and a lower end portion when oriented vertically in an operating state of the parallel-guiding mechanism; a movable parallel leg, having a central longitudinal axis that is also oriented vertically when in the operating state and is surrounded by the stationary parallel leg, the movable parallel leg serving as a force-transmitting connection between a load receiver and a force-measuring cell; a first and a second parallel-guiding element, each of which are connected to the movable parallel leg, with the first parallel-guiding element fastened to the upper end portion of the stationary parallel leg and the second parallel-guiding element fastened to the lower end portion thereof, the respective parallel-guiding elements guiding axial movement of the movable parallel leg; and a means for tilt-adjusting the respective end portions, about at least one tilt axis, to correct a corner load error, the tilt-adjusting means connecting the respective end portions to each other and comprising at least one of: a pair of bending zones, arranged so that one of the tilt axes passes through the pair of bending zones and the central longitudinal axis of the movable parallel leg is in vertical plane between the bending zones; a spherical joint with a contact circle, with one of the tilt axes located in a plane that contains a contact circle and with the central longitudinal axis of the movable parallel leg arranged inside the contact circle, and a ring-shaped constriction having a passage hole and a neutral fiber, with one of the tilt axes located in a plane that contains the neutral fiber and with the central longitudinal axis of the movable parallel leg arranged within the passage hole.
