Abstract

Cette invention concerne un élément d'affichage. Cet élément comprend un boîtier comportant une cuvette hémisphérique prolongée par une partie formant logement pour un noyau en fer doux et entouré par une bobine. Le boîtier est complété par un capot de protection transparent hémisphérique. Une pièce d'affichage de forme sphérique, constituée par deux demi-coquilles de couleurs différenciées, est montée dans le boîtier de façon à pouvoir tourner autour d'un axe vertical. Une butée limite la rotation à 180 degrés et positionne la pièce d'affichage au repos. Des moyens sont prévus pour fixer à l'intérieur de chaque demi-coquille un petit aimant. Les polarités des aimants sont de même sens et l'axe reliant les aimants est perpendiculaire à l'axe de rotation et décalé latéralement par rapport à celui-ci. Cet élément, monté dans des modules et des tableaux d'affichage, fournit une meilleure visibilité latérale et évite le brassage d'air lors de sa commande.
