Abstract

L'invention porte sur une cartouche de disque telle que lorsqu'une griffe d'entraînement applique la force d'ouverture d'un volet sur une surface de la portion (702) de contact de la projection d'un volet latéralement à la direction de coulissement, le verrou du volet associé au boîtier de la cartouche est automatiquement neutralisé pour permettre l'ouverture du volet. La surface de glissement (106) du boîtier de la cartouche associée à la portion (702) de contact de la projection d'un volet (700) est munie d'un orifice (124) de verrouillage, tandis que la portion (702) de contact de la projection est dotée intérieurement d'une projection de verrouillage (712a) capable d'engagement/désengagement avec l'orifice de verrouillage (124) et repoussé vers l'orifice (124) de verrouillage par un ressort (748) à lame. Ledit ressort comporte une surface inclinée (712d) dont la section s'amenuise en allant vers la projection de verrouillage. Un curseur (730) de neutralisation de verrouillage coulissant sur la surface inclinée (712d) est monté entre ladite surface inclinée et la paroi (701) du composant de la portion (702) de contact de la projection associée à la surface de coulissement.
