Patent

CA 2314097

The invention relates to a lock (1) with a latch bolt (9) which protrudes from the lock housing (2). The tail (8) of the latch bolt, which is displaceably guided in the housing, can be pulled back through the action of an arm (20) of a spring-mounted pusher nut (21) and can be locked forwards and backwards through a locking action, by means of a key, a closing cylinder (45), a second nut (47, 49) or similar after a tumbler has first been lifted. A tumbler which can be lifted by a bit (46, 48) is configured in the form of a one-armed lever bar (24). Said lever bar forms turning recesses (25, 26) in which a turning pin (16) on the side of the latch bolt tail engages. The lever bar is mounted around a stay pin (29) located above a latch bolt head (10) on the housing side.

L'invention concerne une serrure (1) comportant un pêne demi-tour (9) faisant saillie hors du boîtier (2) de ladite serrure. La queue (8) dudit pêne demi-tour est guidée de manière à se déplacer dans le boîtier de la serrure, peut être ramenée en arrière sous l'effet de l'action d'un bras (20) de fouillot de poussoir (21) muni de ressorts et peut être fermée vers l'avant et vers l'arrière, par mouvement de fermeture à l'aide d'une clef, d'un barillet (45), d'un second fouillot (47, 49) ou similaire, après levage préalable d'une gâchette. Une gâchette pouvant être levée par un panneton (46, 48) se présente sous forme d'ergot de gâchette (24) à un seul bras formant des cavités tournantes (25, 26) dans lesquelles s'engage une tige tournante (16) côté queue de pêne demi-tour. Ledit ergot de gâchette est monté autour d'un tenon (29) côté boîtier, monté au-dessus de la tête du pêne demi-tour (10).
