Title (EN) A PLAY AND INSTRUCTION MEANS
(FR) ORGANE DE JEU ET D"APPRENTISSAGE
Abstract:
(EN) A play and instruction means on the basis of spherical elements, each element being an assembly of a hollow, spherical envelope made of a non-magnetizable material, in particular a synthetic plastics material, and a permanent bar-like magnet positioned within the envelope, said magnet having head faces curved analogously to the spherical envelope. The weight of the non-magnetic material processed in the spherical element is minimized relatively to the magnetic strength of the bar-like magnet.
(FR) Un organe de jeu et d"apprentissage se compose d"éléments sphériques, chaque élément étant un assemblage d"une enveloppe creuse sphérique composée d"un matériau non-magnétisable, notamment d"un matériau plastique synthétique, et d"un aimant permanent en forme de barre positionné à l"intérieur de l"enveloppe, l"aimant possédant des faces de têtes courbées de manière analogue à l"enveloppe sphérique. Le poids du matériau non-magnétique utilisé dans l"élément sphérique est minime par rapport à la force magnétique de l"aimant en forme de barre.
