Title
(EN) A CYLINDER LOCK/KEY COMBINATION, A KEY AND A KEY BLANK THEREFOR
(FR) COMBINAISON CLE ET SERRURE A BARILLET ET CLE, ET EBAUCHE DE CLE CORRESPONDANTES
Abstract
(EN)
A cylinder lock/key combination includes a lock cylinder (2), a plug (3) rotatably mounted in the cylinder (2) and having a key slot (4), and a number of tumbler pins (6) that are activatable by the code (5a) on the key (5). The key slot carries or houses an element (7) which extends axially along a substantial part of the slot. The key (5) has a blade part (5c) which includes an axially extending portion (5d) in which there is provided a hole (8) for receiving the slot-carried element (7) as the key is inserted into the lock. The slot-carried element (7) and the hole (8) provided in the key (5) are located excentrically in relation to the centre of the plug (3) and accompany rotation of the plug while aided by the key (5). The profile shape of the slot-carried element (7) and the hole (8) in the key may vary within wide limits. The invention also relates to a key belonging to a combination of the aforementioned kind, and to a key blank from which such a key can be produced.
(FR)
Une combinaison clé et serrure à barillet comprend un barillet de serrure (2), un cylindre (3) monté de façon à tourner dans le barillet (2) et doté d'une fente d'entrée (4) pour clé, et un certain nombre de broches de gorge (6) qu'on peut activer grâce au code (5a) inscrit sur la clé (5). La fente d'entrée porte ou renferme un élément (7) placé dans l'axe sur l'essentiel de la longuer de cette fente. La clé (5) comporte une lame (5c) qui présente une partie axiale (5d) où est prévu un orifice (8) qui reçoit l'élément (7) porté par la fente quand on introduit la clé dans la serrure. Cet élément (7) et l'orifice (8) disposé sur la clé (5) sont excentrés par rapport au centre du cylindre (3) et accompagnent la rotation dudit cylindre en étant assistés par la clé (5). Le profil de l'élément (7) porté par la fente et de l'orifice (8) disposé sur la clé peut varier considérablement. L'invention concerne aussi une clé relative à la combinaison sus-mentionnée, et une ébauche qui permet de fabriquer une telle clé.
