A door lock (1), preferably operable both by a mechanical key (C) with a key cylinder (60) and by an electronic signal and having inside and outside handles (A, B) mounted on inside and outside hollow spindles (10, 50), for mounting on a door having an inside face and an outside face, has a cylindrical lock chassis (80) with a provision for retracting a latch bolt (4) in response to rotation of either of the hollow spindles (10, 50); a member (40) for selectively locking the outside spindle (50) against rotation; a reversible electric motor (20) mounted coaxially within the inside spindle (10), the motor being secured against rotation but free to slide axially against resistance provided by a biasing member (21), and having a motor shaft (31) extending through the cylindrical lock chassis (80) to operably engage the member (40) for locking the outside spindle (50); a power supply (101) for the motor (20); and a mechanism (42, 45, 61) for selectively moving the member (40) between locked and unlocked positions.

Serrure de porte (1), de préférence actionnée par une clé mécanique (C) avec un barillet de serrure (60) et par signal électronique, avec poignées interne et externe (A, B) montées sur des axes de poignées creux intérieur et extérieur (10, 50), pour portes ayant une face intérieure et une face extérieure. Un châssis de serrure cylindrique (80) est conçu pour rétracter un pêne demi-tour suite à la rotation de l'un quelconque des axes creux (10, 50); un élément (40) assure le verrouillage sélectif de l'axe extérieur (50) contre la rotation; un moteur électrique réversible (1) monté coaxial dans l'axe intérieur (10), bloqué en rotation mais coulissant axialement sur résistance d'un élément d'appui contraignant (21), a un arbre moteur (31) qui s'étend dans le châssis de serrure cylindrique (80) pour s'enclencher en fonctionnement avec l'élément (40) assurant le verrouillage de l'axe extérieur (50); il existe une source d'alimentation (101) pour le moteur (20) et un mécanisme (42, 45, 61) assurant pour l'élément (40) un changement de position sélectif entre le verrouillage et le déverrouillage.
