Abstract

A lavatory system within an internal cabin of a vehicle includes an enclosure defining an interior chamber, a first lavatory unit within the interior chamber, and a second lavatory within the interior chamber. The first lavatory unit is adjacent to the second lavatory unit. In at least one embodiment, a lavatory within an internal cabin of a vehicle includes an interior chamber defined by one or more outer walls, and a storage compartment extending outwardly from at least one of outer walls. The storage compartment defines an internal storage space that connects to the interior chamber. In at least one embodiment, a lavatory includes a first lavatory unit, a second lavatory adjacent to the first lavatory unit, and a containment compartment common to the first lavatory unit and the second lavatory unit.

First claim

What is claimed is:

1. A lavatory system within an internal cabin of a vehicle, the lavatory system comprising:
an enclosure within the internal cabin, wherein the enclosure defines an interior chamber,
wherein the enclosure comprises:
a first end wall;
an inboard wall indirectly connected to the first end wall, wherein the inboard wall faces an aisle of the internal cabin;
a second end wall connected to the inboard wall, wherein the second end wall is opposite from the first end wall, wherein the second end wall faces an egress path of the internal cabin; and
an outboard wall connected to the first end wall;

a first lavatory unit within the interior chamber, wherein the first lavatory unit is within the enclosure; and
a second lavatory unit within the interior chamber, wherein the second lavatory unit is within the enclosure, wherein the first lavatory unit is inboard in relation to a central longitudinal plane of the internal cabin from the second lavatory unit, wherein the second lavatory unit is outboard in relation to the central longitudinal plane of the internal cabin from the first lavatory unit, and wherein the first lavatory unit is adjacent to the second lavatory unit.

2. The lavatory system of claim 1 , wherein the enclosure is a single monument within the internal cabin.

3. The lavatory system of claim 1 , wherein the first lavatory unit and the second lavatory unit are side-to-side across a portion of the internal cabin.

4. The lavatory system of claim 1 , wherein the second end wall comprises:
a first wall segment that is parallel to the first end wall and perpendicular to the inboard wall;
an angled wall segment that angles toward the first end wall and the outboard wall;
a transition wall segment connected to the angled wall segment, wherein the transition wall segment is parallel to the inboard wall and the outboard wall; and
a second end wall segment connected to the transition wall segment, wherein the second end wall segment is parallel to the first end wall.

5. The lavatory system of claim 1 , wherein the outboard wall is a portion of an outboard wall of the internal cabin.

6. The lavatory system of claim 1 , wherein the first lavatory unit comprises a first passage that connects to an aisle of the internal cabin, wherein a first door is configured to open and close the first passage, wherein the second lavatory unit comprises a second passage that connects to the egress path of the internal cabin, wherein a second door is configured to open and close the second passage.

7. The lavatory system of claim 1 , wherein the first lavatory unit has a first length and the second lavatory unit has a second length, and wherein the first length is greater than the second length.

8. The lavatory system of claim 1 , further comprising a divider wall within the interior chamber, wherein the divider wall separates the first lavatory unit from the second lavatory unit.

9. The lavatory system of claim 8 , wherein the divider wall is moveable between a closed position that separates the interior chamber into the first lavatory unit and the second lavatory unit, and an open position, in which the interior chamber provides an enlarged, expanded single lavatory space.

10. The lavatory system of claim 1 , wherein the first lavatory unit comprises a first sink and a first toilet, and wherein the second lavatory unit comprises a second sink and a second toilet.

11. The lavatory system of claim 1 , further comprising a barrier moveably coupled to one of the first lavatory unit or the second lavatory unit, wherein the barrier is moveable between an extended position and a retracted position, wherein the barrier in the extended position is disposed in front of an exit door of the vehicle, and wherein the exit door is visible within the internal cabin when the barrier is in the retracted position.

12. The lavatory system of claim 11 , wherein the barrier comprises a handle that is configured to be grasped to move the barrier between the extended position and the retracted position.

13. The lavatory system of claim 11 , wherein the barrier comprises a sign that indicates a location of one or both of the first lavatory unit or the second lavatory unit.

14. The lavatory system of claim 1 , further comprising a storage compartment extending outwardly from an outer wall of one or both of the first lavatory unit or the second lavatory unit, wherein the storage compartment defines an internal storage space that connects to the interior chamber.

15. The lavatory system of claim 14 , wherein the storage compartment is at least a portion of a stowage bin assembly.

16. The lavatory system of claim 14 , wherein the storage compartment is at least a portion of an end cap connected to a stowage bin assembly.

17. The lavatory system of claim 14 , further comprising a storage access door disposed between the storage compartment and the interior chamber, wherein the storage access door is configured to be moved between an open position and a closed position, wherein the internal storage space is opened to the interior chamber when the storage access door is in the open position, and wherein the internal storage space is closed to the interior chamber when the storage access door is in the closed position.

18. The lavatory system of claim 14 , wherein the storage compartment is directly connected to the interior chamber, but is not within the interior chamber.

19. The lavatory system of claim 14 , wherein an access opening connects the internal storage space to the interior chamber, wherein the access opening is formed through the outer wall.

20. The lavatory system of claim 14 , wherein the storage compartment comprises a lighting assembly within the internal storage space.

21. The lavatory system of claim 20 , wherein the lighting assembly is operatively coupled to a storage access door of the storage compartment, wherein the lighting assembly is configured to activate to illuminate the internal storage space when the storage access door is opened, and wherein the lighting assembly is configured to be deactivated when the storage access door is closed.

22. The lavatory system of claim 1 , further comprising a containment compartment common to the first lavatory unit and the second lavatory unit.

23. The lavatory system of claim 22 , wherein the containment compartment extends through a divider wall that separates the first lavatory unit from the second lavatory unit.

24. The lavatory system of claim 22 , wherein the containment compartment comprises:
a first interior end wall within the first lavatory unit;
a front wall;
a rear wall;
a base;
an upper counter; and
a second interior end wall opposite from the first interior end wall, wherein the second interior end wall is within the second lavatory unit,
wherein the first interior end wall, the front wall, the rear wall, the base, the upper counter, and the second interior end wall define a containment chamber of the containment compartment.

25. The lavatory system of claim 22 , further comprising a trash container stored within the containment compartment.

26. The lavatory system of claim 22 , wherein the containment compartment further comprises an access door within one of the first lavatory unit or the second lavatory unit, wherein the access door is moveable between an open position and a closed position, wherein the containment compartment is e
