Abstract
To counteract the adverse effects associated with mounting a parallel-guiding device on a supporting part of a balance, the attachment area (30) is located on a portion (14) of the stationary leg (12) of the parallel-guiding device. Portion 14 projects into the space between the two guide links 3 and 6 by which the load-receiving movable leg (11) of the parallelogram is guided in parallel motion relative to the stationary leg (12).
Claims13
An arrangement for mounting in a force measuring apparatus a parallel-guiding device in the shape of a parallelogram, the parallel-guiding device comprising a load receiver formed by a first leg of the parallelogram and serving to receive a load to be measured, the parallel-guiding device further comprising a second leg of the parallelogram and two parallel guide links connecting the first and second legs to one another to complete the parallelogram, the first and second legs being guided in parallel motion relative to one another by the two parallel guide links, wherein the two parallel guide links are rigid in a lengthwise direction thereof but elastically flexible to bend in a plane defined by the parallelogram, wherein the first leg, the second leg, and the two parallel guide links each have opposite lateral side surfaces, wherein the parallel-guiding device is delimited in the direction transverse to the plane of the parallelogram by two lateral boundary surfaces which extend parallel to the plane of the parallelogram and in which the opposite lateral side surfaces of the first and second legs and the two parallel guide links are respectively positioned so that the first and second legs and the guide links extend between the two lateral boundary surfaces, wherein the second leg has a portion projecting into a space inside the parallelogram between the two parallel guide links, wherein the second leg has a single fastening area for firmly attaching the second leg and thus the parallel-guiding device to a supporting part of the force-measuring apparatus, and wherein the fastening area is provided on the portion of the second leg projecting into the space inside the parallelogram.
