A hinging device for windows and doors including a fixed frame and a movable frame, comprising: a first support element to be fastened to the fixed frame bearing a main axis of articulation, a second support element to be fastened to the movable frame, a main lever having a first end articulated to the first support element around the main axis of articulation, a secondary lever articulated to an intermediate region of the main lever, and in which a second end of the secondary lever is articulated to the second support element around a first axis of articulation, and a connecting rod having 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 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. |
