Apparatus for positioning the plane of an apparatus table at an optional inclination

摘要

In an apparatus for positioning the plane (33) of an apparatus table (8) at an optional inclination there are included two rotatable, wedge-shaped housings (4, 6), adapted for giving the plane (33) the selected inclination in a combination of angular rotations. For avoiding a point of singularity within the positioning range for the inclination, an angularity is introduced between the uppermost of the housings (6) and the plane (33).
