Device for opening and closing a pivoting wing

A device for opening and closing a pivoting wing, comprising:

• a stationary support attached to a fixed frame;
• a slide mounted on the exterior surface of the stationary support, the slide being movable along the stationary support along a rectilinear direction between an open wing position, a closed wing position and a locked wing position, wherein the slide comprises a drive pin;
• a pivoting arm articulated to the stationary support about an articulation axis, and having a distal end intended to be connected to the pivoting wing;
• arm forming a transmission mechanism, the transmission mechanism the slide and the pivoting comprising an essentially L-shaped cam engaged by a control pin, the transmission mechanism converts the rectilinear movement of the slide along the rectilinear direction into a pivoting movement of the pivoting arm about the articulation axis;
• a locking assembly mounted on the pivoting wing, comprising a sliding driver, a plurality of transmission rods connected to the sliding driver, a plurality of closing elements attached to the transmission rods and engaged to corresponding strikers in the closed wing position, attached to the fixed frame, the sliding driver having an engagement formation that is engaged by the drive pin of the slide in the closed wing position;
• and
• an auxiliary closing mechanism including a closing pin fixed to the pivoting arm, the closing pin cooperating with an inclined plane integral with the slide, wherein the inclined plane engages the closing pin when the pivoting wing is open and next to the fixed frame, in order to apply an additional closing torque to the pivoting arm during closing of the pivoting wing.
