Aircraft door with additional safety lift

An aircraft door (1) comprising:

• an opening panel (2) provided with engagement abutments (26);
• a frame (3) intended to be fixed to the fuselage (4) of the aircraft and comprising engagement counter-abutments (27);
• a hinge arm (5) supporting the opening panel (2) with respect to the frame (3) and guiding the opening panel (2) between a closed position in which the opening panel (2) is in the frame (3) and an open position in which the opening panel (2) is open and positioned facing the fuselage of the aircraft, freeing the opening of the frame (3);
• a disengagement handle to drive in rotation a rotary control lever (20) that actuated in a direction of disengagement to unlock the opening panel (2);
• the aircraft door comprising:
• a lifting lever (10) linking the hinge arm (5) to the opening panel (2), the lifting lever (10) being driven by the control lever (20) when the control lever (20) is actuated in order to unlock the opening panel (2), the lifting lever (10) guiding the opening panel (2) between a low position of engagement in which the engagement abutments (26) of the opening panel (2) are arranged against the engagement counter-abutments (27) of the frame (3), and a high position of disengagement in which the engagement abutments (26) of the opening panel (2) are disengaged from the engagement counter-abutments (27) by a lifting motion;
• a one-way operating link (18) linking the control lever (20) to the lifting lever (10) so that the rotation of the control lever (20) in the direction of disengagement drives the pivoting of the lifting lever (10) and the lifting of the opening panel (2) with respect to the frame (3), from the low position of engagement to the high position of disengagement, the one-way operating link (18) being designed to drive the lifting lever (10) only when the control lever (20) is actuated in the direction of disengagement;
• a device for immobilizing the control lever (20) when the door is in open position.

• the aircraft door comprising:
• a lifting lever (10) linking the hinge arm (5) to the opening panel (2), the lifting lever (10) being driven by the control lever (20) when the control lever (20) is actuated in order to unlock the opening panel (2), the lifting lever (10) guiding the opening panel (2) between a low position of engagement in which the engagement abutments (26) of the opening panel (2) are arranged against the engagement counter-abutments (27) of the frame (3), and a high position of disengagement in which the engagement abutments (26) of the opening panel (2) are disengaged from the engagement counter-abutments (27) by a lifting motion;
• a one-way operating link (18) linking the control lever (20) to the lifting lever (10) so that the rotation of the control lever (20) in the direction of disengagement drives the pivoting of the lifting lever (10) and the lifting of the opening panel (2) with respect to the frame (3), from the low position of engagement to the high position of disengagement, the one-way operating link (18) being designed to drive the lifting lever (10) only when the control lever (20) is actuated in the direction of disengagement;
• and
• wherein the one-way operating link (18) comprises a rod (30) provided at one of its ends a pivot (33) linked to the control lever (20), and provided at the other of its ends with an abutment (19), a ball joint (16) being mounted on a friction ring (31) sliding along the rod (30).
