ABSTRACT:
The suspension (1) permits of the almost frictionless swinging into equilibrium position of an instrument (53) fastened to an instrument holder (5). For the balancing of the weight or the swinging into the position of equilibrium, the spherical end (7) of the instrument holder (5) is raised. In the raised position, there is an approximately punctiform resting surface between the holding part (3), the suspension (1), and the instrument holder (5). After the instrument has swung into the equilibrium position, the spherical end (7) of the instrument holder (5) can be held clamped fast over a large surface by turning the shaft (19) which has eccentric disks (25).
