Abstract

A manipulator comprising a linkage with at least two links (1, 4) which have ball joints (3, 6) at their ends, and a spring device (10) which exerts a tensile force between the links. The spring device (10) comprises a first drawing device (11) with a first angle device (18), a second drawing device (12) with a second angle device (19), which are arranged, displaceable in parallel, side-by-side, and a spring member (13) arranged between the angle devices. The tensile force arises by the spring member exerting a compressive force against the angle devices.
