Abstract

Novelty: a geometrical drawing instrument for rectilinear lines and cycles is disclosed. Constitution: it has a housing 3 meant to receive whatever writing instrument, two at least wheels 1 and one at least rotary articulation (2,5). The wheels 1 allow the geometrical instrument–when manually pushed-to roll onto the drawing surface in a rectilinear mode for drawing up rectilinear lines. Respectively, the articulation(s) (2,5) allow the circular rolling of the drawing instrument onto the drawing surface for drawing up cycles and circular arcs. Purpose: to draw up rectilinear lines of whatever length and cycles/circular arcs of adjustable radius with one single geometrical drawing instrument which can be easily transported and stored up thanks to its small volume.
