The hinge has two pivots (3, 4) between the edge of the opening unit (6) and the jamb (7), located at the top and bottom of the frame and allowing the unit to be opened to up to 180 degrees. The hinge itself is protected by a rubber cover (11), and the edge of the unit has a curved surface (12) created by a semi-rigid strip that prevents the creation of any gap that would allow fingers to be inserted. |
