An auxiliary apparatus at a stand for an optical observation device, such as a surgical microscope is disclosed, which contains a stand at which there is mounted the surgical microscope. The stand comprises a number of rotary and brake bearings, a support arm and a pivotal arm as well as a hinge parallelogram. The surgical microscope or other instrument can be freely adjustable, but fixed in position, throughout a predetermined spatial region as concerns its position and orientation. Arranged at the parallelogram is a web or strap for mounting a support element, at which there is laterally arranged a holder for the attachment of the housing of a brake bearing and a head element. In the head element there is movably mounted by means of a ball hinge element a coupling element structured for receiving and attaching the surgical microscope. In order to level the parallelogram there is arranged a levelling device at the brake bearing and in order to avoid a tilting movement of the parallelogram the suspended microscope is adjustable horizontally and vertically by means of adjustment elements, such as adjustment screws, arranged at the support element. |
