Abstract:
A device for angular adjustment of a direction-indicating object in an arbitrary direction the device comprising:a fixed part;a movable part which is rotatably arranged in relation to the fixed part around a first axis of rotation, the movable part comprises a tube, wherein a first end of the tube is arranged on the fixed part and a second end of the tube comprises an outer edge which is bevelled at a predetermined fixed angle;a direction-indicating part which is rotatably arranged in relation to the bevelled outer edge of the tube around a central axis, which runs parallel with a normal to the outer edge of the tube, wherein the direction-indicating part includes the direction-indicating object;a torsionally rigid coupling is coupled between the fixed part and the direction-indicating part, wherein the direction-indicating part, by means of the torsionally rigid coupling and the outer edge of the tube, performs a nutation movement when the movable part rotates around the first axis of rotation.
