Abstract

a. Structure de grille pour un tube image en couleur ou tube cathodique. b. Structure caractérisée en ce que chaque élément d'arceau a une forme de section donnant des modules de section différents par rapport aux différents axes passant par le centre de gravité de la forme de section, la partie centrale de chaque élément d'arceau étant disposée de façon qu'un axe de la forme de section transversale passant par le centre de gravité perpendiculairement à l'axe du module de section maximum de la surface de la section transversale se trouve dans un plan passant par les lignes d'action des forces agissant sur les éléments du châssis en des points prédéterminés voisins des extrémités respectives des éléments de châssis.
