Abstract (en)

[origin: EP1988339A2] A self-locking safety hinge for opening and closing a hatch, comprising a first fixed element (2). A second movable element (3) is jointly connected to the hatch and is coupled to the first element (2) so that it can rotate. Members (4) for articulation between the first element (2) and the second element (3) can be actuated manually and selectively from a free rotation configuration, in which the hatch can be moved from an open position to a closed position and vice versa, to a safety configuration, in which the hatch is locked stably in the open position by way of retention means (5). The retention means (5) comprise at least one profile (6) formed by the second element (3) and at least one contact surface (7) which ends with at least one rear bevel (8) provided on the first element (2). When the articulation members (4) are in the safety configuration, the profile (6) abuts substantially against the bevel (8) of the contact surface (7). When the articulation members (4) are in the free rotation configuration, the profile (6) is substantially spaced from the contact surface (7). The retention means comprise at least one first wall (9) on the second element (3) which can engage the bevel (8), the bevel (8) having a curvature which is adapted for the automatic lifting of the hatch by sliding the first wall (9) on the bevel (8), as a consequence of manual traction of the hatch in the closure direction from the safety configuration.
