<p>The system has a median rod (7) for maneuvering movable upper and lower rods (5, 6) with respect to a semi-fixed leaf to lock and unlock upper and lower bolts. A lock is carried by a movable leaf, and displaces a dead-bolt (4) in a striker plate of the semi-fixed leaf. The median rod has a locking orifice (10) that receives the dead-bolt, where the orifice is positioned opposite to the dead-bolt when the semi-fixed leaf is in locked position. The median rod has a solid blocking part that partially blocks an inlet passage of the dead-bolt when the semi-fixed leaf is in unlocked position.</p> |
