Abstract

An aircraft lavatory is disclosed herein. The aircraft lavatory includes a standard access door providing access to the aircraft lavatory from at least one of an aisle, a cross aisle, or a passageway of an aircraft, a first moveable wall adjacent the standard access door, the first moveable wall having a first end and a second end and configured to move between a closed position and an open position, the first end of the first moveable wall configured to rotate about a first pivot point, and a second moveable wall adjacent the first moveable wall, the second movable wall having a first end and a second end and configured to move between a closed position and an open position, the first end of the second moveable wall configured to rotate about a second pivot point.

First claim

What is claimed is:

1. An aircraft lavatory, comprising:
a standard access door providing access to the aircraft lavatory from at least one of an aisle, a cross aisle, or a passageway of an aircraft;
a first moveable wall adjacent the standard access door, the first moveable wall having a first end and a second end and configured to move between a closed position and an open position, the first end of the first moveable wall configured to rotate about a first pivot point and into the aisle, the cross aisle, or the passageway of the aircraft; and
a second moveable wall adjacent the first moveable wall, the second movable wall having a first end and a second end and configured to move between a closed position and an open position, the first end of the second moveable wall configured to rotate about a second pivot point opposite a rotation of the first movable wall and into a space adjacent to the aisle, the cross aisle, or the passageway of the aircraft, wherein in the closed positions the second end of the first movable wall is coupled to the second end of the second movable wall.

2. The aircraft lavatory of claim 1 , wherein the first moveable wall is configured to rotate at least 45° about the first pivot point from the closed position to the open position.

3. The aircraft lavatory of claim 1 , wherein the second moveable wall is configured to rotate at least 80° about the second pivot point from the closed position to the open position.

4. The aircraft lavatory of claim 1 , further comprising:
a latch configured to secure the second end of the first moveable wall to the second end of the second moveable wall when in the first moveable wall and the second moveable wall are in the closed position.

5. The aircraft lavatory of claim 1 , wherein the first moveable wall includes a first portion extending in a first direction coupled to a second portion extending in a second direction orthogonal to the first direction.

6. The aircraft lavatory of claim 1 , further comprising:
a first cabin attendant seat coupled to the first moveable wall; and
a second cabin attendant seat coupled to the second moveable wall.

7. The aircraft lavatory of claim 1 , further comprising:
a post configured to secure the standard access door in a closed position, wherein the first end of the first moveable wall is coupled to the post, the post being the first pivot point.

8. The aircraft lavatory of claim 7 , further comprising:
a first fixed wall having a first side and a second side and extending in a first direction;
a second fixed wall having a first side and a second side, the first side of the second fixed wall coupled to the first side of the first fixed wall, the second fixed wall extending in a second direction that is orthogonal to the first direction, wherein the standard access door is coupled to the second fixed wall; and
a third fixed wall having a first side and a second side, the first side of the third fixed wall coupled to the second side of the first fixed wall, the third fixed wall extending in the second direction, wherein the second moveable wall is coupled to the second side of the third fixed wall.

9. The aircraft lavatory of claim 1 , wherein the aircraft lavatory is configured to receive a mobility device through an opening that is defined by the first moveable wall and the second moveable wall being in the open position.

10. An aircraft, comprising:
at least one lavatory, wherein the at least one lavatory includes:
a standard access door providing standard access to the at least one lavatory from an aisle, a cross aisle, or a passageway of the aircraft;
a first moveable wall having a first end and a second end and configured to move between a closed position and an open position, the first end of the first moveable wall configured to rotate about a first pivot point and into the aisle, the cross aisle, or the passageway of the aircraft; and

a second moveable wall having a first end and a second end and configured to move between a closed position and an open position, the first end of the second moveable wall configured to rotate about a second pivot point opposite a rotation of the first movable wall and into a space adjacent to the aisle, the cross aisle, or the passageway of the aircraft, wherein in the closed positions the second end of the first movable wall is coupled to the second end of the second movable wall.

11. The aircraft of claim 10 , wherein the first moveable wall is configured to rotate at least 45° about the first pivot point from the closed position to the open position.

12. The aircraft of claim 10 , wherein the second moveable wall is configured to rotate at least 80° about the second pivot point from the closed position to the open position.

13. The aircraft of claim 10 , the at least one lavatory further comprising:
a latch configured to secure the second end of the first moveable wall to the second end of the second moveable wall when in the first moveable wall and the second moveable wall are in the closed position.

14. The aircraft of claim 10 , wherein the first moveable wall includes a first portion extending in a first direction coupled to a second portion extending in a second direction orthogonal to the first direction.

15. The aircraft of claim 10 , further comprising:
a first cabin attendant seat coupled to the first moveable wall; and
a second cabin attendant seat coupled to the second moveable wall.

16. The aircraft of claim 10 , the at least one lavatory further comprising:
a post configured to secure the standard access door in a closed position, wherein the first end of the first moveable wall is coupled to the post, the post being the first pivot point.

17. The aircraft of claim 10 , further comprising:
a first aisle adjacent the at least one lavatory; and
a first curtain configured to extend across the first aisle, the first curtain providing privacy for the at least one lavatory.

18. The aircraft of claim 17 , further comprising:
a second aisle adjacent the at least one lavatory; and
a second curtain configured to extend across the second aisle, the second curtain providing privacy for the at least one lavatory.

19. The aircraft of claim 10 , the at least one lavatory further comprising:
a first fixed wall having a first side and a second side and extending in a first direction;
a second fixed wall having a first side and a second side, the first side of the second fixed wall coupled to the first side of the first fixed wall, the second fixed wall extending in a second direction that is orthogonal to the first direction, wherein the standard access door is coupled to the second fixed wall; and
a third fixed wall having a first side and a second side, the first side of the third fixed wall coupled to the second side of the first fixed wall, the third fixed wall extending in the second direction, wherein the second moveable wall is coupled to the second side of the third fixed wall.

20. The aircraft of claim 10 , wherein the at least one lavatory is configured to receive a mobility device through an opening defined by the first moveable wall and the second moveable wall being in the open position.
