CA 2542100

A door lock with controllable handle operation including a bolt (3), a follower (5) for moving the bolt and an operation axis (4), on both ends of which an actuator can be installed for operating the follower (5), whereby force transmission from either side of the lock to the follower (5) is established by means of movable coupling members (10a, 10b), which are controlled by a solenoid arrangement (8, 9) or the like, and in which the follower (5) is provided with two separate torsion units (6a, 6b) installed on the operation axis (4) on different sides of the follower (5) and turnably secured thereto, which units can be connected to force transmission with the follower (5) by utilising said coupling members (10a, 10b). The door lock comprises a selecting member (7) movable from one lock side to the other, which member retains the torsion unit (6a, 6b) selected in each case to be unturnable with respect to the follower (5), so that force transmission from the operation axis (4) to the follower (5) is connected on that particular side of the lock, and on the other side of the lock, force transmission from the operation axis (4) to the follower (5) can be selectively either connected or disconnected by means of said coupling members (10a, 10b) under the control of the solenoid arrangement (8, 9).

L'invention porte sur une serrure de porte à commande de fonctionnement de la poignée comportant: un pêne (3); un fouillot (5), agissant sur le pêne et sur un axe de commande, et aux deux extrémités duquel on peut installer un actionneur commandant le fonctionnement du fouillot (5), la transmission de force par un ou l'autre côté du la serrure au fouillot (5) s'appliquant par l'intermédiaire d'éléments mobiles de couplage (10a, 10b) commandés par un solénoïde (8, 9) ou analogue. Le fouillot (5) est muni de deux unités de torsion séparées (6a, 6b) placés sur l'axe de commande (4) de part et d'autre du fouillot (5) et lui étant fixés pivotants, lesdites unités pouvant être reliées à la transmission de force par le fouillot (5) au moyen desdits éléments de couplage (10a, 10b). La serrure comporte un sélecteur (7) mobile d'un côté de la serrure à l'autre et retenant l'unité de torsion (6a, 6b) sélectionnée dans chaque cas pour ne pas pouvoir tourner par rapport au fouillot (5) de manière à ce que la transmission de force de l'axe (4) de commande au fouillot (5) soit reliée à ce côté de la serrure et que de l'autre côté de la serrure on puisse au choix connecter ou déconnecter la transmission de force de l'axe de commande à au fouillot (5) à l'aide desdits éléments de couplage (10a, 10b) en agissant sur le solénoïde (8, 9).
