<p>The door hinge has a stationary portion for fixing to the frame and an opening one secured to the door. It incorporates a pin bracket (7) with a plate bearing against the frame (1) and two bosses with holes in line to accommodate the pin. A locking piece fits in the groove formed in the frame, and the bracket is secured to it by a screw (8), whose head fits between the two bosses. A protective component (9) is shaped to fit between the bosses and mask the space between them, so that the hinge cannot be unscrewed from its mounting when the door is shut. This component has a drilling accommodating the hinge pin.</p> |
