<p>In scales having a weighing plate (32) that is guided vertically by means of a lying parallelogram system (8,18,22,28) it has been common standard that this system has to be 'stiff', such that the weighing plate is downwardly displaced in parallel even if it is loaded only at a peripheral, local area. In connection with the invention it has been realized that this arrangement can give rise to excessive and demolishing influence on an associated weighing cell (36,52) in case of impact-like loadings of the weighing plate, and on this background it is proposed that the parallelogram system be designed less stiff and more resilient than conventionally. In practice this design implies that a corner of the weighing plate (32) can be locally depressed against an underlying depression stop (6) without the other corners of the weighing plate thereby being depressed against respective, associated depression stops (6). <IMAGE></p> |
