A device for opening and closing a pivoting wing (14), comprising:
- a stationary support (22) intended to be attached to a fixed frame (12),
- a slide (32) movable relative to the stationary support (22) along a rectilinear direction (B) between an open wing position and a closed and locked wing position,
- a pivoting arm (52) articulated to the stationary support (22) about an articulation axis (C), and having a distal end intended to be connected to the wing (14),
- a transmission mechanism (43) associated with the slide (32) and the arm (52), comprising an essentially L-shaped cam (46) engaged by a control pin (64), the transmission mechanism (43) being configured to transform the rectilinear movement of the slide (32) along said rectilinear direction (B) into a pivoting movement of the arm (52) about said pivot axis (C), and
- an auxiliary closing mechanism (73) associated with the slide (32) and the arm (52), including a closing pin (74) cooperating with an inclined plane (76), wherein said inclined plane (76) is configured to engage said closing pin (74) when the wing (14) is open and next to the fixed frame (12), in order to apply an additional closing torque to the arm (52) during closing of the wing. |
