Emergency opening device for an aircraft door, comprising a telescopic operating member

An emergency opening device for an aircraft door fitted with an opening mechanism, the device comprising:

• an actuating device (2, 5) to actuate the opening mechanism, which switch between a passive state and an active state of activating the opening mechanism, and which comprise:
• a tubular operating member (2) provided with a first end (3) connected to the door, and with a locking second end (4);
• an elastic compression device (5) arranged between a fixed end-stop element (6) and the operating member (2);
• a retainer for restraining the locking second end (4) to move between a closed position of locking of the locking second end (4), in a position of the operating member (2) corresponding to the passive state of the actuating device in which position the elastic device (5) are kept compressed, and an open position of releasing of the locking second end (4) allowing the operating member (2) to move along an axis of movement (X) toward a position corresponding to the active state of the actuating device, under the effect of the force resulting from the expansion of the elastic device (5);
• for activating the actuating device (2, 5) designed to bring about the opening of the retainer;
• the emergency opening device being comprising:
• a first-end element (10) and a second-end element (11) which are able to move freely relative to one another in translation along the axis of movement (X), the first end (3) of the operating member (2) being situated on the first-end element (10) and the locking second end (4) of the operating member (2) being situated on the second-end element (11);
• the fixed end-stop element (6) comprises a fixing device (18) for fixing it to an aircraft door element;
• an axis cylinder (15) extending along the axis of movement (X) is fixed to the fixed end-stop element (6), the second-end element (11) being mounted with the ability to slide along the axis of movement (X) on the axis cylinder (15);
• the retainer comprises a rotary latch (9) that opens under load capable of rotational motion about the axis of movement (X), the rotary latch (9) being axially fixed on the axis cylinder (15) between two axial end-stops, the rotary latch (9) being in non-sliding pivoting connection with the axis cylinder (15), the rotary latch (9) comprising at least one blade (27) extending parallel to the axis of movement (X) and designed to retain, by traction on a stop surface (30, 43), the locking second end (4) of the second-end element (11);
• the activating device of the actuating device (2, 5) comprise a lever (31) solidly attached to the rotary latch (9) and allowing the latch (9) to be forced to rotate.
