Adjustable support for optical observation instrument
Abstract
Abstract An adjustable stand for an optical observation instrument, especially for a binocular microscope, the position and/or orientation of which can be adjusted and fixed in a spatial area. A three-axis full Cardan rod assembly connects the observation instrument with a freely adjustable terminal piece of a pivot rod assembly. The Cardan rod assembly and the pivot rod assembly incorporating a number of bearing means each providing singleaxis pivot joints, and each of said bearing means is formed of relatively frictionless roller body bearings. Each of the number of roller body bearings incorporating a respective electrically operable blocking mechanism which can be selectively electrically switched-in and switched-out in such a manner that the observation instrument can be selectively fixed and adjusted, respectively, in each desired orientational position. Operating means render possible a freely combined rotational movement of the three-axis full Cardan rod assembly about three axial directions which are perpendicular to one another, said operating means comprising a forehead support and a mouthpiece by means of which the electrical blocking mechanisms can be selectively released or fixed.
