INVENTOR: RUDOLF HELLER INVENTION: SUPPORT APPARATUS FOR AN OPTICAL OBSERVATION DEVICE ABSTRACT OF THE DISCLOSURE The support apparatus in the form of a stand possesses an arm component projecting transversely from a stand component. A surgical operating microscope is arranged at the end of the arm component. A guide linkage with a double scissors type carrier linkage whose movement is combined with an extension movement is provided for the displacement of the operating microscope in a direction transverse to the stand component. This extension movement is controlled by a control linkage in such a way that the upper end of the carrier linkage which carries the stand arm component moves along a straight line. There is thus no need for a counterweight for the transverse movement of the operating microscope over a surgical operating table. A first counterweight for the upwardly and downwardly directed swinging movement of the stand arm component is enclosed in a space saving manner within a housing of the stand component, conjointly with a substantial portion of the guide linkage. The connection between the arm component of the stand and the first counterweight is effected through linkages a predominant portion of which are likewise substantially accommodated within the housing.
