    • The invention relates to the depiction by drawing of a large number of geometrically harmonic figures, especially cycloids, and their modifications. The solution according to the invention is that one or more rotating wheels (figures) are linked by adhesive friction or toothing to a base wheel or base figure (2) locked on a guide rail (see drawing (4)) by additional push-on shaft mountings. By horizontal pivoting about the axis of the base wheel, a corresponding rotation of the rotating wheels (1) is achieved as a consequence of the adhesive friction or toothing, in the course of which one (or more) radially adjustable pencil(s), fixed to the extended shaft of a particular rotating wheel, draw(s) the geometrical figure on a paper inserted underneath. Rubbers (6) or tension springs between the shaft mountings bring about rolling of the rotating figures and the movement of the shaft mountings along the guide rail in the case of rotating figures which are not positioned centrally or have corners (triangle, square, etc.) or elliptical shapes. A special plug-in design of the individual parts permits rapid conversion and a broad embodiment of the drawing instrument. The instrument is suitable as a creative toy, as a drawing instrument or as a presentation or demonstration instrument in schools.
