Abstract

L'invention concerne un cylindre de serrure (1) comprenant un dispositif de fermeture avec clé (2) adaptée. Le cylindre de serrure (1) présente un boîtier de cylindre (3) et une âme de cylindre (5) montée dans un alésage de montage (4) du boîtier de cylindre (3). La clé (2) peut être insérée dans un canal de clé (6) de l'âme de cylindre (5). L'âme de cylindre (5) présente au moins un alésage d'âme (7) qui débouche dans le canal de clé (6) et le boîtier de cylindre (3) présente au moins un alésage de boîtier (8) aligné sur l'alésage d'âme (7). Une tige ferromagnétique ou magnétique de maintien (9), exempte de ressort, est placée dans l'alésage de boîtier (8) et, lorsque la clé (2) n'est pas enfoncée, s'enfonce par certaines parties dans l'alésage d'âme (7). Lorsque la clé (2) est enfoncée, elle possède une découpe de codage (10) alignée par rapport à l'alésage d'âme (7) et une partie magnétique (11) voisine de cette découpe, et la tige de maintien (9) attirée dans la découpe de codage (10) par la partie magnétique (11) de la clé (2) qui a été enfoncée est située entièrement à l'intérieur de l'alésage d'âme (7). Pour améliorer les capacités techniques de fermeture du cylindre de serrure et en particulier la technique de fabrication d'une clé associée, l'invention propose de former la partie magnétique d'un aimant permanent (11) disposé dans une découpe (19) située sur le côté large de la clé (2).
