Abstract

A hinging device for windows and doors includes a fixed frame and a movable frame, a first support element, a second support element, a main lever, a secondary lever, and a connecting arm. The first support element is fastened to the fixed frame bearing a main axis of articulation. The second support element is fastened to the movable frame. The main lever has a first end articulated to the first support element around the main axis of articulation. The secondary lever is articulated to an intermediate region of the main lever. A second end of the secondary lever is articulated to the second support element around a first axis of articulation. The connecting rod has a first end articulated to the second end of the main lever and a second end articulated to the second support element around a second axis of articulation. The first and the second axes of articulation are in a fixed position relative to the second support element and they can be inclined in such a way as to allow a displacement of the second support element between a first position corresponding to the position of closed or wing-opened movable frame and a second position corresponding to the position of swivel-opened movable frame.
