Title
(EN) CYLINDER AND ASSOCIATED KEY
(FR) BARILLET ET CLÉ ASSOCIÉE
Abstract
(EN)
A cylinder (1) with associated key (6), comprising a stator (2) provided with a longitudinal cavity (3) for accommodating a rotor (4) with a longitudinal recess (5) for the insertion of a coded key (6). The rotor (4) and the stator (2) comprise channels (7), which are substantially aligned and face each other when the cylinder (1) is in the closed configuration, for accommodating respective pins (8), complementary pins (9) and any elastic means (7a). The rotor (4) comprises at least one second passage (10), which is not aligned with respect to the channels (7) and faces, in the closed configuration of the cylinder (1), a corresponding cavity (1 1) of the stator (2), the passage and the cavity accommodating at least one respective movable peg (12), whose head (13) rests against the blade edge (14) of the key (6) when the key is inserted in the recess (5). The key (6) is provided with suitable contoured regions (15) on its blade edge (14) at the surfaces that face said pegs (12) when inserted in the recess (5). Each peg (12) has its base (16) inside the respective cavity (11) so as to block the rotation of the rotor (4) with respect to the stator (2) when a key (6) lacking the corresponding contoured regions (15) is inserted.
(FR)
L'invention concerne un barillet (1) et une clé associée (6), comprenant un stator (2) doté d'une cavité longitudinale (3) pour recevoir un rotor (4) présentant un renfoncement longitudinal (5) permettant l'introduction d'une clé codée (6). Le rotor (4) et le stator (6) comprennent des canaux (7), qui sont sensiblement alignés et se font face lorsque le cylindre (1) est dans la configuration fermée, pour recevoir des broches respectives (8), des broches complémentaires (9) et tout moyen élastique (7a). Le rotor (4) comprend au moins un second passage (10), qui n'est pas aligné par rapport aux canaux (7) et fait face, dans la configuration fermée du barillet (1), à une cavité correspondante (11) du stator (2), le passage et la cavité recevant au moins une cheville mobile respective (12), dont la tête (13) repose contre le bord de lame (14) de la clé (6) lorsque la clé est introduite dans le renfoncement (5). Sur son bord de lame (14), la clé (6) est dotée de régions de forme appropriées (15) aux surfaces qui font face auxdites chevilles (12) lorsque la clé est introduite dans le renfoncement (5). La base (16) de chaque cheville (12) est à l'intérieur de la cavité respective (11) de façon à bloquer la rotation du rotor (4) par rapport au stator (2) lorsqu'une clé (6) ne présentant pas les formes correspondantes (15) est introduite.
