Abstract

L'invention concerne un instrument de dessin (2) servant à diviser des angles en différentes parties. Pour la réalisation d'une bissection, l'instrument selon l'invention comporte une simple rainure (27) et des points équidistants (21, 22, 23, 24) le long d'une bissectrice perpendiculaire. Pour la réalisation d'autres divisions, par exemple en trois et en quatre, l'instrument comporte des rainures (33A, 34A, 35A, 33B, 34B, 35B) de forme appropriée permettant de définir le lieu où se situe le point de division. Pour définir le point, on trace un arc coupant les lieux et on relie le point d'intersection avec le sommet de l'angle. L'instrument peut également comprendre d'autres éléments comme des règles, des rapporteurs et des trous calibrés pour tracer des cercles et des arcs.
