Abstract

An aircraft lavatory unit that includes a diaper changing platform has a first side wall and a second side wall located on both sides of a toilet bowl, and a rear surface wall located to the rear of the toilet bowl. Handrails are provided on the first side wall and the second side wall. The diaper changing platform can be pivoted between a stowage position in which it is stowed in a stowage recess in the rear surface wall, and a usage position in which the diaper changing platform is lowered above the toilet bowl. The diaper changing platform is configured so that in the usage position it is supported by placing both sides of the bottom surface on the handrails of the first side wall and the second side wall.

First claim

What is claimed is:

1. An aircraft lavatory unit having a toilet bowl provided within a structural frame,
the structural frame including two first wall faces disposed opposite each other, and a second wall face that connects the first wall faces, the second wall face being formed into a shape that includes a curved surface along a side wall of a fuselage of the aircraft,
the toilet bowl being disposed so that the two first wall faces are located at sides of the toilet bowl, and the second wall face being located to a rear of the toilet bowl,
handrails, each having an elongated shape, being provided at positions on the two first wall faces sandwiching the toilet bowl, the handrails for use when sitting down onto a toilet seat of the toilet bowl and when standing up from the toilet seat,
a diaper changing platform being provided on the second wall face at a position above the toilet bowl with a hinge as a support point, that is capable of being pivoted between a stowage position conforming to the second wall face and a usage position when it is lowered to above the toilet bowl,
a thickness of the second wall face being configured to become gradually thinner in a direction from a lower part to an upper part of the second wall face,
the second wall face being provided with a stowage recess capable of stowing the diaper changing platform thereinto formed in the curved surface at a position higher than a position of the toilet bowl, the second wall face having a thickness formed by the stowage recess so that a bottom surface of the diaper changing platform and the second wall face are continuous when the diaper changing platform is stowed into the stowage recess, and
the diaper changing platform being disposed at a position directly above the toilet bowl in the usage position and being supported by the handrails at side portions of the diaper changing platform on sides of the two first wall faces.

2. The aircraft lavatory unit according to claim 1 , wherein the structural frame includes a floor,
the handrails have an elongated shape and extend parallel to the floor, and
the support of the side portions by the handrails in the usage position is through contact of an entire length in a longitudinal direction of the handrails with a bottom surface of the side portions of the diaper changing platform.

3. The aircraft lavatory unit according to claim 2 , wherein the structural frame includes a rectangular shaped floor, a front surface wall that rises from a first long side of two long sides of the floor, a rear surface wall that rises from a second long side of the two long sides, a first side wall that rises from a first short side of two short sides of the floor, and a second side wall that rises from a second short side of the two short sides,
the toilet bowl is disposed at an end portion of the floor near the first side wall,
a doorway is provided in the front surface wall at an end portion near the second side wall,
the two first wall faces are the wall faces of the front surface wall and the rear surface wall, and
the second wall face is the wall face of the first side wall.

4. The aircraft lavatory unit according to claim 1 , wherein the structural frame includes a rectangular shaped floor, a front surface wall that rises from a first long side of two long sides of the floor, a rear surface wall that rises from a second long side of the two long sides, a first side wall that rises from a first short side of two short sides of the floor, and a second side wall that rises from a second short side of the two short sides,
the toilet bowl is disposed at an end portion of the floor near the first side wall,
a doorway is provided in the front surface wall at an end portion near the second side wall,
the two first wall faces are the wall faces of the front surface wall and the rear surface wall, and
the second wall face is the wall face of the first side wall.
