Abstract

A lavatory monument assembly that includes an enclosure having front and rear walls and that defines an enclosure interior. A divider wall that extends between the front and rear walls, and a divider door that is movable between closed and opened positions. In the closed position the divider door divides the enclosure interior into first and second lavatory interiors. The divider wall includes first and second sections and the divider door includes first and second portions that meet at an obtuse angle. The divider door is pivotably attached to the divider wall. The front wall includes first and second lavatory doors that are both movable between closed and opened positions and provide access to the first and second lavatory interiors. A first toilet is positioned adjacent the rear wall in the first lavatory interior and a second toilet is positioned adjacent the rear wall in the second lavatory interior.

First claim

What is claimed is:

1. A lavatory monument assembly configured to be positioned in an interior of an aircraft, the lavatory monument assembly comprising: an enclosure that includes a front wall and a rear wall and that defines an enclosure interior, a divider wall that extends between the front wall and the rear wall, wherein the divider wall includes a divider door that is movable between a closed position and an open position, wherein in the closed position the divider door divides the enclosure interior into a first lavatory interior and a second lavatory interior, wherein the divider wall includes a first section and a second section, wherein the divider door includes a first portion and a second portion that meet at an obtuse angle, wherein the first portion is stationary with respect to the second portion, and wherein the divider door is pivotably attached to the divider wall, wherein the front wall comprises a first lavatory door that is movable between a closed and an open position and provides access to the first lavatory interior, a second lavatory door that is movable between a closed and an open position and provides access to the second lavatory interior, and wherein a first toilet is positioned adjacent the rear wall in the first lavatory interior and a second toilet is positioned adjacent the rear wall in the second lavatory interior.

2. The lavatory monument assembly of claim 1 wherein the second portion of the divider door is not parallel with the first section or the second section of the divider wall.

3. The lavatory monument assembly of claim 1 wherein the second section of the divider wall is positioned between the first and second toilets and the first section of the divider wall is positioned between the first and second lavatory doors, wherein the divider door is hingedly connected to the second section of the divider wall.

4. The lavatory monument assembly of claim 1 wherein the first section of the divider wall is not aligned with the second section of the divider wall.

5. The lavatory monument assembly of claim 4 wherein the first section of the divider wall and the second section of the divider wall extend parallel to one another.

6. The lavatory monument assembly of claim 5 wherein the first portion of the divider door extends parallel to the first and second sections of the divider wall.

7. The lavatory monument assembly of claim 6 wherein the second portion of the divider door does not extend parallel to the first and second sections of the divider wall.

8. The lavatory monument assembly of claim 3 wherein the first toilet is positioned closer to the front wall than the second toilet, wherein the divider door pivots into the first lavatory interior to move to the open position.

9. A method of operating a lavatory monument assembly that includes a front wall, a rear wall and a divider wall that extends between the front wall and the rear wall to divide the lavatory monument assembly into first and second lavatory interiors, the method comprising the steps of:
(a) moving a first lavatory door from a closed position to an open position to provide a first lavatory door opening,
(b) moving a divider door from a closed position to an open position to provide a divider door opening, wherein the divider door includes a first portion and a second portion that meet at an obtuse angle, wherein the first portion is stationary with respect to the second portion,
(c) moving a wheelchair through the first lavatory door opening and into the first lavatory interior, and
(d) moving the wheelchair at least partially through the divider door opening such that the wheelchair is positioned partially in the first lavatory interior and partially in the second lavatory interior.

10. The method of claim 9 wherein the divider wall includes a first section and a second section, and wherein the second portion of the divider door is not parallel with the first section or the second section of the divider wall.

11. The method of claim 10 wherein a first toilet is positioned adjacent the rear wall in the first lavatory interior and a second toilet is positioned adjacent the rear wall in the second lavatory interior, wherein the second section of the divider wall is positioned between the first and second toilets and the first section of the divider wall is positioned between the first and second lavatory doors, wherein the divider door is hingedly connected to the second section of the divider wall, and wherein the step (b) includes pivoting the divider door toward the first toilet.

12. The method of claim 11 wherein the first toilet is positioned closer to the front wall than the second toilet, wherein in the open position the second portion of the divider door partially defines an angled entry path.

13. A lavatory monument assembly configured to be positioned in an interior of an aircraft, the lavatory monument assembly comprising:
an enclosure that includes a front wall and a rear wall and that defines an enclosure interior,
a divider wall that extends between the front wall and the rear wall, wherein the divider wall includes a divider door that is movable between a closed position and an open position, wherein in the closed position the divider door divides the enclosure interior into a first lavatory interior and a second lavatory interior, wherein the front wall comprises a first lavatory door that is movable between a closed and an open position and provides access to the first lavatory interior, a second lavatory door that is movable between a closed and an open position and provides access to the second lavatory interior, wherein a first toilet is positioned adjacent the rear wall in the first lavatory interior and a second toilet is positioned adjacent the rear wall in the second lavatory interior,
wherein the divider wall includes a first section and a second section, wherein the divider door includes a first portion and a second portion that meet at an obtuse angle, wherein the first portion is stationary with respect to the second portion, wherein the second section of the divider wall is positioned between the first and second toilets and the first section of the divider wall is positioned between the first and second lavatory doors, wherein the divider door is hingedly connected to the second section of the divider wall, wherein the first section of the divider wall is not aligned with and extends parallel to the second section of the divider wall, wherein the first portion of the divider door extends parallel to the first and second sections of the divider wall, and wherein the second portion of the divider door does not extend parallel to the first and second sections of the divider wall.

14. The lavatory monument assembly of claim 13 wherein the first toilet is positioned closer to the front wall than the second toilet, wherein the divider door pivots into the first lavatory interior to move to the open position.
