Abstract

L'invention concerne les dispositifs de dessin. Un dispositif de dessin de type magnétique comprend essentiellement une planche à dessin 20 qui porte des couches horizontales de matière magnétique 22, et une équerre qui porte des couches de matière magnétique qui sont horizontales dans une partie 25 et verticales dans une partie 24. Cette configuration verrouille l'équerre sur la planche à dessin en lui permettant de se déplacer horizontalement ou verticalement, en fonction de son orientation. Application au dessin industriel.The invention relates to drawing devices. A magnetic type drawing device essentially comprises a drawing board 20 which carries horizontal layers of magnetic material 22, and a set square which carries layers of magnetic material which are horizontal in part 25 and vertical in part 24. This configuration locks the square to the drawing board allowing it to move horizontally or vertically, depending on its orientation. Application to industrial design.
