Abstract

L’invention concerne un jouet magnétique de type bloc polyédrique construit de façon à ce qu’un aimant figure de manière amovible sur chaque surface d’un polyèdre. Le jouet magnétique comprend une pluralité de blocs polyédriques (31) et d’aimants (32). Chacun des blocs comprend un espace de mouvement d’aimant (R) s’étalant sur chaque surface du polyèdre, subdivisé en une pluralité de petits espaces de mouvement (R s) par une pluralité de cloisons (W), recouvert d’une unité de couverture de façon à ce que chaque extrémité ouverte soit isolée de l’extérieur et ayant la forme d’un sillon droit. Les aimants sont, de préférence, insérés dans les petits espaces de mouvement figurant en des extrémités opposées. Le jouet magnétique de type bloc polyédrique autorise la zone de contact ou la position de couplage à être modifiée comme on le souhaite, lorsque des blocs d'unité entrent l’un l’autre en contact, créant ainsi des formes variées de structure et, par conséquent, étant utiles pour l’éducation.
