Abstract

L'invention concerne un noyau de serrure antivol (5) muni d'un passage de clé incurvé (10), de trous de billes de verrouillage (20) et de billes de verrouillage (3). La partie incurvée du passage de clé (10) est située à proximité de la partie avant de l'orifice de clé. Le noyau de serrure (5) est constitué d'un noyau de serrure supérieur (11) et d'un noyau de serrure inférieur (12) demi-cylindriques. Le noyau de serrure supérieur (11) et le noyau de serrure inférieur (12) sont reliés de façon fixe pour former un cylindre complet. Le noyau de serrure supérieur (11) et le noyau de serrure inférieur (12) comportent respectivement un passage incurvé. Les passages se font face et s'étendent axialement le long du noyau de serrure (5). Lorsque le noyau de serrure supérieur (11) et le noyau de serrure inférieur (12) sont connectés en une unité, les passages respectifs coopèrent pour former un passage de clé (10) dans lequel est introduite la clé de type chaîne. L'extrémité avant du passage de clé (10) comporte une section à trous du boîtier de clé (1) qui correspond au boîtier de clé rigide (1) de la clé de type chaîne utilisée par le noyau de serrure (5). Une clé de type chaîne correspondante est également décrite, laquelle coopère avec le noyau de serrure (5). La clé transmet un couple à travers le boîtier de clé rigide (1) de façon à empêcher la clé de se rompre dans le passage de clé (10).
