Adjustable parallelogram guide, in particular for a gravimetric measuring instrument

The invention relates to a parallel guide that can be used in a gravimetric measuring instrument and comprises a fixed parallel limb which is vertically arranged in the operating state of the parallel guide and has an upper end region and a lower end region. The fixed parallel limb surrounds a mobile parallel limb having a central longitudinal axis extending vertically during operation. The parallel guide also comprises a first parallel guiding element fixed to the upper end region, and a second parallel guiding element fixed to the lower end region, said guiding elements enabling the mobile parallel limb to be connected to the fixed parallel limb and guided in a vertically mobile manner. The mobile parallel limb can be connected to a load receiver and to a load cell in such a way as to transmit a load. The upper end region and the lower end region are interconnected by means of at least one pair of bending points and/or at least one ball-and-socket joint and/or at least one annular constriction, the end regions being mutually pivotable about at least one pivoting axis in order to correct a corner load error.
