A lock assembly (10) comprising a casing (12), a lever (14) rotatably attached to the casing (12), the lever (14) having a spindle (18) attached thereto, a motor (30) secured to the casing (12), the motor (30) having a shaft (31), a substantially cylindrical member (40) attached to the motor shaft (31) and having a helically extending groove, and an interfering member (50) threadedly and non-rotatably engaged with the helically extending groove of the cylindrical member (40). The interfering member (50) moves into the locked position to prevent rotation of the lever (14) when the motor shaft (31) rotates in one direction. The interfering member (40) moves into the unlocked position to allow rotation of the lever (14) when the motor shaft (31) rotates in an opposite direction.
Cette invention concerne un ensemble serrure (10) comprenant un boîtier (12), un levier (14) monté rotatif sur le boîtier (12), et auquel est fixée une tige (18), un moteur électrique (30) fixé au boîtier (12) et comportant un axe (31), un élément sensiblement cylindrique (40) fixé à l'axe (31) du moteur, et comportant une gorge hélicoïdale, et enfin, un élément intermédiaire (50) fileté et non rotatif qui entre en contact avec la gorge hélicoïdale de l'élément cylindrique (40). L'élément intermédiaire (50) passe en position de verrouillage de manière à empêcher la rotation du levier (14) lorsque l'axe (31) du moteur tourne dans un sens donné. Ce même élément intermédiaire (50) peut également passer en position de déverrouillage de manière à permettre au levier (14) de tourner lorsque l'axe (31) du moteur tourne dans le sens opposé.
