Claims (12)

1. Hinge for doors and windows containing: - the first body (1) of the hinge, which has a central recess (2); wherein the first body (1) of the hinge is connected to the profile of the column (3) of the fixed frame equipped with a cavity with an indentation to accommodate the central recess (2); a rotating pin (4) defining an axis (Z) of vertical rotation of the hinge (100) which is positioned and confined within the recess (2) of the first body (1) of the hinge; wherein the first wing (5) is integral with the rotating pin (4) and radiates radially from the rotating pin (4); - the second body (6) of the hinge with a flat profile attached to the outer surface of the column profile (7) of the movable arm or frame; wherein the second wing (8) is integral with the second body (6) of the hinge and springs from the second body (6) of the hinge; - device (9) for a stable connection between the first (5) and second (8) wings placed between the first (5) and second (8) wings; characterized in that the device (9) for stable connection between the first (5) and the second (8) wings contains at least one pair of pins (10, 11) parallel to each other, connected to the first wing (5); wherein said pair of wedges (10, 11) spring transversely from the first wing (5), parallel to the axis (Z) of vertical rotation, and slidingly connected, in a pair of corresponding cavities (12, 13) made on the second wing (8) on such way to form one rigid wing by means of at least one partial overlapping of the first (5) and second (8) wings. 2. A hinge according to claim 1, wherein at least a pair of pins (10, 11) connected to the first wing (5) has a cylindrical shape and a pair of cavities (12, 13) has a suitable shape for accommodating a pair of pins (10, 11). 3. Hinge according to claim 1 or 2, wherein the first wing (5) is formed from the first (5a) and second (5b) segments, mutually consecutive and placed at an angle to each other, starting from the rotating pin (4); where on the second segment (5b) of the first wing (5) which is farthest from the rotating wedge (4), a part of the protruding pair of wedges (10, 11) is located. 4. A hinge in accordance with claim 3, wherein two cavities (14, 15) are formed on the second segment (5b) of the first wing (5) for partial accommodation of the corresponding pins (10, 11); wherein between the second segment (5b) and each wedge (10, 11) there are inserted means (16) for stabilizing the portion of the cylindrical pair of wedges (10, 11) located in the cavity (14, 15) made on the second segment (5b). 5. A hinge according to claim 4, wherein the stabilization means (16) comprise screw means (16a) which can be placed in corresponding holes made on the outer surface of the second segment (5b) of the first wing (5) in such a way as to block by interfering with the pins (10, 11) in the cavities (14, 15). 6. A hinge according to claim 4, wherein the stabilizing means (16) comprise, on each pin (10, 11), an end provided with a broad head (16b) and a threaded section (16c) which can be screwed onto the lower end of the respective cavity (14, 15) after inserting and passing the wedge (10, 11) along the corresponding cavity (14, 15). 7. A hinge according to any one of claims 2 to 6, wherein a pair of cylindrical pins (10, 11) are positioned, the first (10), at the junction of the first (5a) and second (5b) segments, and the second (11) ) at the free end of the second segment (5b). 8. A hinge according to any of the preceding claims, wherein the second wing (8) forms one body with the second body (6) of the hinge connected to the outer surface of the column profile (7) of the movable arm or frame and in such a way as to form a kind of `L` with the second body (6) of the hinge; wherein the second wing (8) has two cylindrical cavities (12, 13) for accommodating the protruding part of the cylindrical pair of wedges (10, 11); whereby two cylindrical cavities (12, 13) are made, respectively, at the point of connection of the second wing (8) and the second body (6) of the hinge, and at the free end of the second wing (8). 9. A hinge according to any of the preceding claims, comprising elements (26) for adjustment along the vertical axis (Z) of the hinge (100) positioned between the first (5) and second (8) wings and, between the two pins (10, 11), and which act in opposite directions between the first wing (5) and the second wing (8); wherein said adjustment elements (26) are configured to vary the height distance between the first (5) and second (8) wings. 10. A hinge according to any of the preceding claims, wherein the rotating pin (4) of the hinge (100) is composed of a first lower sleeve (17), from which springs the first wing (5), inside which it is rotatably located, in a manner to pass, the first portion of the wedge (4) which has an end hinged in the recess (2) of the first body (1) of the hinge; of the second upper sleeve (18) in which the second part of the wedge (4) is placed in such a way that the second hinged end emerges in the recess (2) of the first body (1) of the hinge. 11. A hinge according to any one of the preceding claims, wherein the recess (2) of the first body (1) of the hinge has a longitudinal extension and a depth configured to accommodate, at least partially, the first (5) and second (8) wings folded in mutual movement towards each other the two surfaces on which the first (1) and second (6) body of the hinge corresponding to the closed position of the mobile arm or frame on the fixed frame are attached. 12. A hinge according to any of the preceding claims, wherein the first body (1) of the hinge has two end flanges (19, 20) configured to enable relative attachment to the outer surface of the column profile (3) of the fixed shoulder.
