Stand for a surgical microscope with a parallelogram support driven by an energy storing device

A stand for a surgical microscope, comprising:

• a vertical support;
• at least one horizontal support having a first end facing toward the surgical microscope;
• a first vertical articulation unit that is connected said first end;
• a second articulation unit determining an oblique pivot axis and being connected to the first vertical articulation unit;
• a displacement unit that is attached to the second articulation unit and has multiple degrees of freedom for displacement and balancing of an optics carrier carrying the surgical microscope;
• at least one pivot support encompassed by the displacement unit;
• and
• means for displacing the optics carrier in an X direction extending horizontally and transversely to the oblique pivot axis, said means for displacing being provided at the pivot support;
• wherein said pivot support comprises:
• a pivotable parallelogram support that is provided with at least one of a spring and a gas damper as an energy storing device that interconnects and supports movement of the movable parts in the interior of the parallelogram support assisting with a stored force in a displacement movement;
• and
• a holding arm that is attached to the pivotable parallelogram support and is configured such that it simultaneously serves as a means for displacing the optics carrier in the X direction.
