A lift and slide wing comprising, at its lateral edge, a recess in which are housed operational mechanisms for releasing the wing from the counter-edge of the frame and allowing it to open. In the recess of the wing (2) moreover actuation means for actuating the aforementioned operational mechanisms are housed, such actuation means comprising an electric motor (16) which actuates a worm screw (19) with which a nut (20), which can translate parallel to said screw, is thread-engaged. The nut (20) is connected integral in translation with connection rods (23,24) having rack portions that are engaged with gearwheels (21,22) having square-shaped tangs inserted with prismatic engagement inside the follower of said operational mechanisms. |
