ABSTRACT:
The invention relates to a stand arrangement (100) for a medical-optical instrument. The stand arrangement includes a first link (104) which is pivotally supported on a holding unit (101) by a first rotational joint. The stand arrangement (100) further includes a second link (106) which is rotatably connected to the first link (104) via a second rotational joint (105). A take-up unit (109) for medical-optical equipment is held in a forward section (107, 108) of the second link (106) by a third rotational joint. The take-up unit (109) includes a front link (111) which, in turn, is connected via a third link (112) and a fourth link (113) to the second rotational joint (105). The holding unit (101) and the fourth link (113) are coupled with the aid of a toothed gear unit (118) in such a manner that the orientation of the front link (111) does not change with the movement of the first link (104).
