Abstract
Disclosed is a spatially-adjustable supporting frame for a surgical microscope unit which can be selectively locked in any adjusted position. The frame includes a hinged parallelogram which can be pivoted about a bearing supported on a column. The hinged parallelogram carries a second structure in the form of a coupled-hinge parallelogram which, in turn, carries the surgical microscope. Two counterweights are independently adjustable along paths parallel with two adjacent sides of the hinged parallelogram to permit the continuous balancing of the weight of the surgical microscope.
