SAFETY HINGE

摘要

Using a conventional hinge that is fixed to the frame, the complementary hinge that is fixed to the door has a sliding element (3) that comes out perpendicularly from its base plate (1) and is intended to be located in a blind hole on the edge of the door. Said sliding element is closed on the free end thereof by a cover (12) and has a pair of opposite longitudinal guides (4). Corresponding sets of ball bearings enabling sliding of a pad (8) that is provided with complementary guides (4') for the above-mentioned set of ball bearings are mounted in said pair of guides, the pad being an elbowed extension of an arm (9) ending in the bushing (10) or hinge and by means of which said hinge is connected in an articulated manner to the hinge that is fixed to the door. Complementarily, the sliding element (3) and the pad (8) define a cylindrical chamber (5-5') in which a spring is seated (7) that presses the leaf against the frame in the case of the upper hinge and separates these elements in the case of the lower hinge.
