Abstract

A hinged device for at least one door (46.1, 46.2) of an aircraft nacelle (40), whereby the door is able to block an opening (44) that is made in the fairing of the nacelle, the device including a base to which is connected at least one door, able to occupy a first retracted state in which the base is located at least in part inside the nacelle and a second extended state in which the base is located outside the fairing of the nacelle so as to be able to move, in a direction that is essentially parallel to the longitudinal axis of the nacelle, outside of the nacelle by entraining the at least one door (46.1, 46.2) to release the opening (44) at least in part.

Claims

1. A hinged device for at least one door (46.1, 46.2) of an aircraft nacelle (40), said at least one door being able to block an opening (44) that is made in a fairing of the nacelle,

wherein said hinged device comprises a base (54) located in a low part of the nacelle to which is connected said at least one door by a pivoting axis (56), said pivoting axis (56) being essentially parallel to a longitudinal axis (42) of the nacelle, said base (54) being able to occupy a first retracted state in which said base (54) is located at least in part inside the nacelle and a second extended state in which said base (54) is located outside the fairing of the nacelle so as to be able to move, in a direction that is essentially parallel to the longitudinal axis of the nacelle, outside of said nacelle by entraining said at least one door (46.1, 46.2) so that movement of the base causes the at least one door to provide access to the opening,

wherein said hinged device further comprises at least one connecting and holding element of which a first end is connected to said at least one door and a second end is connected to the nacelle, and

at least one of the first and second ends of said at least one connecting and holding element is able to slide along a slide that is made at said at least one door.

2. The hinged device for at least one door of an aircraft nacelle according to claim 1, wherein said at least one connecting and holding element comprises a connecting rod (78) that is connected at a first end to the nacelle and comprises at the second end a roller (82) that can move along the slide (76) that is integral with the at least one door.

3. The hinged device for at least one door of an aircraft nacelle according to claim 1, wherein said base (54) is connected to the nacelle by means of at least one connecting element of which a first end is connected to the nacelle and a second end is connected to said base, whereby at least one of the two ends is able to slide along a slide that is integral with the base.

4. The hinged device for at least one door of an aircraft nacelle according to claim 3, wherein said at least one connecting element is in the form of a deformable parallelogram (58) that includes two connecting elements (60.1, 60.2) whose first ends are connected to the nacelle and whose second ends are able to slide along at least one slide (62) that is integral with said base (54), whereby the connecting elements (60.1, 60.2) have lengths that are adapted so that the base (54) can move outside the fairing in the extended state.

5. The hinged device for at least one door of an aircraft nacelle according to claim 4, wherein said opening comprises a front lateral edge parallel with a lateral axis and wherein one of the two connecting elements (60.1, 60.2) is connected at said front lateral edge (48) of the opening of the nacelle so that said base (54) moves toward a front of a nacelle.

6. An aircraft nacelle, comprising:

at least one opening (44) that can be blocked by at least one door, said at least one door being connected to the nacelle by a hinged device wherein said hinged device comprises a base (54) located in a low part of the nacelle to which is connected said at least one door by a pivoting axis (56), said pivoting axis (56) being essentially parallel to a longitudinal axis (42) of the nacelle, said base (54) being able to occupy a first retracted state in which said base (54) is located at least in part inside the nacelle and a second extended state in which said base (54) is located outside a fairing of the nacelle so as to be able to move, in a direction that is essentially parallel to the longitudinal axis of the nacelle, outside of said nacelle by entraining said at least one door (46.1, 46.2), so that movement of the base causes the at least one door to provide access to the opening.

7. The aircraft nacelle according to claim 6, wherein the base (54) is connected to the nacelle by at least one connecting element comprising a deformable parallelogram.

8. The aircraft nacelle according to claim 6, wherein said at least one door (46.1, 46.2) is connected to the nacelle via at least one connecting and holding element that comes in a form of a connecting rod (78) that is connected at a first end to the nacelle and that comprises at an other end a roller (82) that can move along a slide (76) that is integral with the at least one door and wherein the anchoring point to the nacelle of a first end of the connecting rod (78) is offset relative to an end of the slide (76) against which the roller (82) is able to abut.

9. The aircraft nacelle according to claim 6, wherein said at least one door (46.1, 46.2) is connected to the nacelle via at least one connecting and holding element that comes in a form of a connecting rod (78) that is connected at a first end to the nacelle and that comprises at an other end a roller (82) that is able to move along a slide (76) that is integral with the at least one door and wherein a length of the slide is adjusted so that the roller (82) of the connecting rod (78) abuts against its end when the at least one door is in an open position in which the opening is released at least in part.
