A hinging device for windows and doors including a fixed frame (14) and a movable frame (16), comprising:
- a first support element (26) to be fastened to the fixed frame (14) bearing a main axis of articulation (34),
- a second support element (28) to be fastened to the movable frame (16),
- a main lever (38) having a first end (40) articulated to the first support element (26) around the main axis of articulation (34),
- a secondary lever (46) articulated to an intermediate region (42) of the main lever (38), and in which a second end (52) of the secondary lever (46) is articulated to the second support element (28) around a first axis of articulation (60), and
- a connecting rod (56) having a first end articulated to the second end (44) of the main lever (38) and a second end (94) articulated to the second support element (28) around a second axis of articulation (62). The first and the second axes of articulation (60, 62) are in fixed position relative to the second support element (28) and they can be inclined in such a way as to allow a displacement of the second support element (28) between a first position corresponding to the position of closed or wing-opened movable frame (16) and a second position corresponding to the position of swivel-opened movable frame (16). |
