Abstract: The device comprises a main body, a fixing member affording fixing of a door leaf to the main body, a ball socket able to drive the main body under the effect of a motor, a roller able to move between (a) an active locking position in which the roller locks the ball socket with respect to the main body, in a closed position of the door leaf and (b) an inactive unlocking position in which a the roller allows displacement of the ball socket with respect to the main body. The device also includes a sleeve that allows a small movement of the fixing member with respect to the ball socket in a displacement direction from the closed position of the door leaf. The device further comprises a tooth that inhibits sleeve to immobilize the fixing member with respect to the ball socket, at least in translation in the displacement direction, when the roller is in the inactive position.

Abstract: The device comprises a main body, fixing means affording the fixing of the leaf to the body, drive means able to drive a body under the effect of motor means, locking means able to move between an active locking position in which they lock the drive means with respect to the body, in the closed position of the leaf, and an inactive unlocking position in which they allow a displacement of the drive means with respect to this body, and partial opening means able to allow a small movement of the fixing means with respect to the drive means, in the displacement direction, from the closed position of the leaf. The device further comprises means for inhibiting the partial opening means, able to immobilize the fixing means with respect to the drive means, at least in translation in said displacement direction, when the locking means are in their inactive position.
