HINGES FOR DOORS OR WINDOWS

Abstract

A hinge for doors and windows is described which comprises a first hinge body (1) which has a central recess (2) and is associated with a corresponding cavity which is formed in the profile of a vertical element (3) of the fixed frame a pin (4) which defines an axis (Z) of vertical rotation of the hinge (100) and is placed and held within the recess (2) of the first hinge body (1) a first flap (5) integrated with the rotation pin (4) which projects radially from the rotation pin (4) a second hinge body (6) with a flat profile fixed to the outer surface of the profile of a vertical element (7) of a movable frame or retractable frame a second flap (8) integrated with the second hinge body (6) which projects from the second hinge body (6) a device (9) for a fixed connection between the first (5) and the second (8) flap which is positioned between the first (5) and theof a second blade (8) wherein the device (9) for fixed connection between the first (5) and the second (8) blade comprises a pair of pins (10, 11) parallel to each other, associated with the first blade (5), said pair of pins (10, 11) projecting from the first blade (5), parallel to the axis (Z) of vertical rotation and are coupled by means of sliding with a pair of corresponding cavities (12, 13) formed in the second blade (8) in such a way as to form a single rigid blade.
