Description

Technical Field

[0001] In a first aspect, the present invention relates to a lavatory device for an aircraft cabin, an aircraft cabin, an aircraft, and a method for modifying the lavatory device for an aircraft cabin.

[0002] In the second part, the present invention relates to a partition wall for an aircraft lavatory in the cabin of an aircraft, a lavatory for an aircraft cabin, a kit for converting a lavatory with two adjacent lavatories into an enlarged lavatory suitable for passengers with mobility impairments (PRM), an aircraft cabin, an aircraft, and a method for transforming the lavatory in an aircraft cabin. Background Technology

[0003] Passenger restrooms are installed on the aircraft to provide sanitation services for passengers. Considering space economy, aircraft restrooms are relatively small to maximize available space for passenger seating. However, passengers with disabilities (PRMs), particularly wheelchair users, may require more restroom space. WO 2011 / 101385 A2 provides a solution with a movable partition. By moving the partition to the open position, two restrooms are combined to form a larger compartment, which can then be used by the PRM. Furthermore, WO 2012 / 110643A1 provides a similar solution in a modular design. However, the need for further improvements in space utilization has been indicated. As a further consideration, a growing need for further optimization of the use of available space has been demonstrated. Summary of the Invention

[0004] Therefore, it may be necessary to make better use of the available space in the bathroom.

[0005] The object of the present invention is achieved through the subject matter of the main aspects of the invention; other embodiments are incorporated into other aspects of the invention. It should be noted that the following aspects of the invention are also applicable to: aircraft cabins, cabins for aircraft, aircraft, and methods for transforming the lavatory facilities of aircraft cabins. It should also be noted that the described aspects are also applicable to: partition walls for aircraft lavatory facilities in aircraft cabins, lavatory facilities for aircraft cabins, kits for converting lavatory facilities with two adjacent lavatories into enlarged lavatories suitable for PRM, cabins for aircraft, aircraft, and methods for transforming the lavatory facilities of aircraft cabins.

[0006] According to a first aspect of the invention, a lavatory device for an aircraft cabin is provided. The device includes: a first lavatory compartment accessible from a passageway area through a first door; and a second lavatory compartment accessible from a passageway area through a second door. A movable dual-function partition wall is arranged between the first and second lavatory compartments. The dual-function partition wall is movable between a primary position and a secondary position. In the primary position, the dual-function partition wall separates the first and second lavatory compartments, and in the secondary position, the dual-function partition wall moves to a position outside the first and second lavatory compartments, whereby the first and second lavatory compartments provide an enlarged public lavatory. In the secondary position, the dual-function partition wall is at least partially arranged outside the lavatory device and within the passageway area outside the first and second lavatory compartments.

[0007] As a result, the usable bathroom space inside is maximized.

[0008] According to the example, in a secondary location, a partition wall at least partially encloses the portion of the passageway area in front of the toilet fixtures, thereby providing additional partition space as an extension of the public restroom.

[0009] According to the example, in a secondary location, the partition wall is arranged to extend toward the building located on the opposite side of the passageway area, such that an additional space is provided in front of the first or second door, separated from the adjacent passageway or seating space, which is provided as an extension of the public restroom.

[0010] According to the example, the partition wall includes a main wall panel and an extension section located at the distal edge of the main wall panel, the extension section being used to extend the effective length of the partition wall in a secondary position. The extension section is movable from a retracted position to an extended position. In a first option, the extension section is a pivoting section attached to the main panel in a manner capable of pivoting about a vertical axis. In a second option, the extension section is a translational section attached to the distal front end of the main panel and capable of translating in a telescoping manner.

[0011] As shown in the example, a movable bridging section is provided on a structure located on the opposite side of the passageway area. The bridging section can move between a parking position and a deployment position. When the partition wall is in a secondary position and the bridging section is in its deployment position, the partition wall can connect to the bridging section.

[0012] According to the example, the partition wall includes at least two wall panel sections connected by vertically hinged connectors. In a secondary location, the partition wall is removed from the device and folded along the vertically hinged connectors and attached by the distal end of the partition wall to provide a supplementary space partition in front of a first or second door, which is provided as a vaulted extension of the public restroom.

[0013] According to the example, the partition wall includes at least two wall panel sections connected by vertically hinged connectors. In a secondary location, the partition wall is removed from the device and folded along the vertically hinged connectors and attached via the distal end of the partition wall to a cabin wall structure located on the side of a first or second restroom, thereby providing an additional space adjacent to the first or second door, which serves as an extension of the public restroom.

[0014] According to the example, in the secondary position, the partition wall is arranged to extend from the toilet fixture to a structure located on the opposite side of the passageway area. To achieve the secondary position, in its fully extended state, the partition wall can be moved via its proximal edge from a position between the first and second doors toward a position opposite to the first and second doors. Furthermore, in the secondary position, the partition wall is connected via its proximal end to a portion of the toilet fixture located on the lateral side of the first or second door, such that an extended additional space, separated from the adjacent passageway or seating space, is provided in front of the first and second doors, serving as an extension of the public restroom.

[0015] According to the example, in a secondary location, the partition wall is positioned in front of either the first or second bathroom door. Alternatively, the partition wall comprises two sections connected in a manner that allows it to fold along a vertical axis, so that it folds in front of either the first or second door in a secondary location.

[0016] As illustrated in the example, the partition wall includes an extendable enclosed section at its upper edge. This enclosed section can be removed in a secondary location to enclose additional partition space upwards.

[0017] According to a first aspect of the invention, a cabin for an aircraft is also provided. The cabin includes at least one passenger seating area with a plurality of passenger seats. The cabin also includes at least one aisle area for allowing passengers to move within the cabin. The cabin further includes at least one toilet structure. The at least one toilet structure includes at least one toilet device according to the invention.

[0018] According to the example, at least one corridor area includes at least one longitudinally arranged corridor. Access to the first and second sanitary cubicles is possible from the corridor.

[0019] As shown in the example, an entrance area is provided, located next to the aircraft door; the entrance area includes an entrance passageway area. Access to the first and second sanitary cubicles is possible from the entrance passageway area.

[0020] According to a first aspect of the invention, an aircraft is also provided. The aircraft includes a fuselage and a cabin space disposed within the fuselage. In a first option, at least one lavatory device according to one of the examples described above is provided within the cabin space. In a second option, a cabin according to one of the examples described above is provided within the cabin space.

[0021] According to a first aspect of the present invention, a method for modifying a toilet facility in an aircraft cabin is also provided. The method includes the following steps:

[0022] - A toilet installation is provided, comprising a first toilet cubicle accessible from a passageway area via a first door and a second toilet cubicle accessible from a passageway area via a second door; and

[0023] - A dual-function partition wall disposed between a first toilet stall and a second toilet stall is moved from a primary position to a secondary position. In order to move the partition wall, the wall is released and then moved to provide an enlarged toilet, and the wall is also placed in a passageway area, wherein the partition wall is fixed in the passageway area; wherein, in the primary position, the dual-function partition wall separates the first toilet stall and the second toilet stall; in the secondary position, the dual-function partition wall is moved to a position outside the first toilet stall and the second toilet stall; in the secondary position, the first toilet stall and the second toilet stall provide an enlarged public toilet; and in the secondary position, the dual-function partition wall is at least partially disposed outside the toilet unit and in the passageway area outside the first toilet stall and the second toilet stall.

[0024] In the example, the step of moving the partition wall to a secondary location includes at least partially enclosing the portion of the passageway area in front of the toilet fixtures, thereby providing additional partition space as an extension of the public restroom for use by passengers with mobility impairments.

[0025] On the one hand, a partition wall is a changeable wall that performs two different functions in two different locations.

[0026] According to one approach, a double toilet with two toilet spaces is provided, which can be transformed into an enlarged toilet with increased user space by moving the partition wall between the two toilet spaces to the outside of the toilet and enclosing the passageway outside the toilet so that this space can be used as an additional private user space. Therefore, not only are two toilet spaces provided for example, for passengers with mobility impairments, but also an additional space is provided.

[0027] According to one aspect, a partition wall is provided that allows two toilet spaces, i.e., two separate toilets or toilet cubicles, to be transformed into an enlarged public toilet with increased space available to users.

[0028] According to a second aspect of the invention, a partition wall is provided for an aircraft lavatory in the cabin of an aircraft. The partition wall includes a main wall panel, a secondary wall panel, and a mounting assembly. The main wall panel is configured to be fixedly disposed between a first lavatory and a second lavatory in a dual-lavatory arrangement. The secondary wall panel is configured to be removably disposed between the first and second lavatorys, such that in a first attached position, the secondary wall panel and the main wall panel provide a separation between the first and second lavatorys. The secondary wall panel is movable to a detached second position outside the lavatory arrangement, in which the separation between the first and second lavatorys is eliminated. The mounting assembly is configured to removably install the secondary wall panel in the first position to at least one of the following: a lavatory enclosure and a main wall panel.

[0029] As a result, restrooms can be easily transformed while ensuring maximum use of the expanded space within the public restroom.

[0030] According to the example, the mounting components are configured to removably attach a secondary wall panel in a second position to, for example, the side of a toilet enclosure facing the cabin and / or another structure inside the cabin.

[0031] According to a second aspect of the invention, a toilet arrangement for an aircraft cabin is also provided. The arrangement includes a first toilet compartment accessible from a passageway area and a second toilet compartment accessible from a passageway area. A partition wall, according to an example of the above-described examples, is arranged between the first and second toilet compartments. In a first position, the partition wall separates the first and second toilet compartments. In a second position, a secondary wall panel is moved to the outside of the first and second toilet compartments, in which the first and second toilet compartments provide an enlarged public toilet.

[0032] According to the example, one can enter a first toilet stall from the corridor area through a first door, and a second toilet stall from the corridor area through a second door. In the second location, secondary wall panels are arranged, for example, to extend from the toilet stall toward a structure located on the opposite side of the corridor area, such that additional space, separated from the adjacent corridor or seating space, is provided in front of the first or second door, which serves as an extension of the public restroom.

[0033] According to the example, in the second location, the secondary wall panel is attached to the open distal edge of the first or second bathroom door.

[0034] According to a second aspect of the invention, a kit is also provided for converting a toilet unit having two adjacent toilets into an enlarged toilet suitable for PRM. The kit includes a partition wall according to one example of the above-described examples, the partition wall being configured to replace an existing rigid partition wall between the two adjacent toilets. The kit also includes main fittings for securely mounting the main wall panels inside the toilet unit.

[0035] According to the example, the mounting assembly of the partition wall includes at least one retaining device configured to removably mount a secondary wall panel in a second position to a structure such as the cabin-facing side of a toilet enclosure and / or another structure within the cabin.

[0036] According to a second aspect of the invention, a cabin for an aircraft is also provided. The cabin includes at least one passenger seating area with a plurality of passenger seats, at least one aisle area for allowing passengers to move within the cabin, and at least one toilet structure. The at least one toilet structure includes at least one toilet unit according to one of the examples described above.

[0037] According to a second aspect of the invention, an aircraft is also provided. The aircraft includes a fuselage and a cabin space disposed within the fuselage. The cabin space is provided with: 1) at least one toilet facility according to one of the examples described above; or ii) an aircraft cabin according to one of the examples described above.

[0038] According to a second aspect of the present invention, a method for modifying a toilet facility in an aircraft cabin is also provided. The method includes the following steps:

[0039] - A toilet installation is provided, comprising a first toilet cubicle accessible from a passageway area through a first door and a second toilet cubicle accessible from a passageway area through a second door; a partition wall is provided between the first toilet cubicle and the second toilet cubicle;

[0040] - Release the mounting assembly, which removably mounts the secondary wall panel in the first position to at least one of the following: a bathroom enclosure and a main wall panel; and

[0041] - The secondary wall panel of the partition wall is moved from a first position to a second position. In the first position, the partition wall separates the first sanitary compartment from the second sanitary compartment. In the second position, the secondary wall panel is located outside the first and second sanitary compartments, where the first and second sanitary compartments provide an enlarged public toilet.

[0042] According to one aspect, the present invention relates to transforming the partition between two adjacent restrooms in an aircraft to provide a larger public restroom. The partition wall is a transformable wall that performs two different functions in two different locations.

[0043] According to one approach, a double restroom with two toilet spaces is provided, which can be transformed into an enlarged restroom with increased user space by moving a portion of the partition wall between the two toilet spaces to the outside of the restroom and enclosing the passageway space outside the restroom, thus enabling that space to be used as an additional private user space. Therefore, not only are two toilet spaces provided for example, for use by passengers with mobility impairments, but also an additional space is offered.

[0044] The technological advantage is that a specific folding mechanism for the partition wall inside the bathroom is not necessary. Furthermore, by freely moving the wall panel to the outside of the bathroom, it avoids obstructing items and space inside the bathroom. The partition wall panel to be removed can be equipped with a fairly simple disassembly mechanism.

[0045] The economic benefit is that, when using removable partitions in PRM mode, the partitions create additional private space within the aircraft. The existing layout of the aircraft can be maintained without losing the seating arrangement for the toilets, even if it meets DOT2 standards.

[0046] The removable wall panel is easy for workers to use and offers a more robust, reliable, and lightweight solution compared to folding or sliding mechanisms.

[0047] According to one approach, the partition wall separating two adjacent toilets can be partially and completely detached from the toilet shell structure and moved outside the toilet. Outside the toilet, the partition wall can be attached to an open toilet door on one side and to another cabin module in the passageway area, such as a partition, kitchen, or toilet, on the other side. This "retracted" position of the partition wall panel results in additional private space, which is beneficial for the use of the PRM.

[0048] In one option, the removable partition panel has hinges to allow it to fold for better operation and to compensate for tolerances in “visual barrier” mode.

[0049] According to one interpretation, the partition wall of the toilet comprises two panels, one of which is removable. In the first, and arguably most common, case, the partition wall is closed, providing two separate toilets. In this configuration, the second wall panel is attached to the toilet shell structure. In an intermediate configuration, the second wall panel is detached from the toilet shell structure, folded, and removed to the outside of the toilet. In a second configuration, the second wall panel is detached from the toilet shell structure and attached to an open toilet door on one side, and to a cabin module such as a partition, kitchen, or other toilet on the outer side. For PRM use, both toilet doors can be closed, or one toilet door can be opened.

[0050] These and other aspects of the invention will become apparent and will be explained with reference to the embodiments described below. Attached Figure Description

[0071] Figure 18The basic steps of an example method for transforming the toilet facilities in an aircraft cabin are shown. Detailed Implementation

[0072] Some embodiments will now be described in more detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same elements, even in different drawings. The description, including detailed constructions and elements, is provided to aid in a comprehensive understanding of the exemplary embodiments. Furthermore, well-known functions or structures are not described in detail, as such details would obscure the embodiments. Additionally, expressions such as "at least one of..." when preceding a list of elements modify the entire list of elements rather than individual elements within that list.

[0073] Aspect I: Figures 1a to 1c An example of a toilet installation 10 is schematically shown. The toilet installation 10 includes a first toilet cubicle 12 accessible from a passageway area 14 via a first door 16. The toilet installation 10 also includes a second toilet cubicle 18 accessible from the passageway area via a second door 20. A movable dual-function partition wall 22 is arranged between the first toilet cubicle 12 and the second toilet cubicle 18. The dual-function partition wall 22 is movable between a primary position P1 and a secondary position P2. In the primary position P1, the dual-function partition wall 22 separates the first toilet cubicle 12 from the second toilet cubicle 18, and in the secondary position P2, the dual-function partition wall 22 is moved to a position outside the first toilet cubicle 12 and the second toilet cubicle 18, where the first toilet cubicle 12 and the second toilet cubicle 18 provide an enlarged public toilet 24. In the secondary position P2, the dual-function partition wall 22 is at least partially arranged outside the toilet installation 10 and within the passageway area 14 outside the first toilet cubicle 12 and the second toilet cubicle 18.

[0074] Figure 1a The partition wall 22, located in the main position P1, is shown.

[0075] Figure 1b The diagram shows the state during the movement of partition wall 22. Figure 1a Examples. Arrow 26 indicates the motion, such as translation, which is followed by another motion, such as pivoting.

[0076] Figure 1c The secondary position P2 is shown. Figure 1a Examples.

[0077] The first toilet cubicle 12 has a first toilet 28 and a first sink 30 or washbasin. The second toilet cubicle 18 has a second toilet 32 ​​and a second sink 34 or washbasin.

[0078] As an example, expanded public restrooms 24 are provided for use by passengers with mobility impairments.

[0079] The term "toilet cubicle" refers to an enclosed space equipped with toilet facilities such as a toilet, urinal, sink, mirror, or trash can. Toilet cubicles can also be referred to as restrooms, washrooms, toilet stalls, or passenger service rooms. Toilet cubicles can also be called toilet spaces.

[0080] The term "aisle area" refers to the following parts of the aircraft cabin: these parts are designed for the passage of passengers and crew, the movement of passengers and crew on board, and the movement of service units such as trolleys used for in-flight service. Aisle areas are typically adjacent to seating areas with passenger seats. Aisle areas can also be referred to as aisle layout structures.

[0081] The term "partition wall" refers to the wall that separates the space of the first toilet stall from the space of the second toilet stall, that is, the first toilet space from the second toilet space.

[0082] The term "dual-function" refers to a wall that can move between two positions to achieve two different purposes.

[0083] The term "primary position" refers to the first or main position used in a bathroom. The primary position can also be referred to as the dual-toilet position.

[0084] The term "secondary position" refers to a secondary or auxiliary position for use in the bathroom. The secondary position can also be referred to as the PRM toilet usage position.

[0085] The term "public toilet" refers to an enlarged toilet space where two toilets are enclosed, but only one toilet is actually usable.

[0086] The term "exterior of a toilet unit" refers to the removal of the partition wall from the interior of the toilet unit and its movement to the front of the toilet unit's housing.

[0087] In a secondary location, the dual-function partition wall is moved to a position outside the bathroom fixture.

[0088] The expanded public restrooms are designed for use by passengers with mobility impairments (PRMs), such as those using wheelchairs. For a PRM to use the restroom, they must be able to transfer from their wheelchair to the toilet seat and then back to the wheelchair. In addition to extra handles and grips throughout the cabin, more space must be provided for this usage scenario. Further space for assistive personnel may also be needed for PRMs to use the restrooms.

[0089] To save space, the toilet cubicles were designed for standard use, allowing for a layout with minimal footprint. However, these cubicles were too small for use by PRMs. To provide larger cubicles suitable for PRM use, two cubicles were combined by removing the partition wall. Instead of folding and storing the wall inside the toilet, the wall was removed from the cubicle and fixed in a different location. Therefore, the usable space inside the cubicle was maximized.

[0090] The expanded public restrooms allow for wheelchair access. Furthermore, the expanded public restrooms also provide space for assistance personnel.

[0091] In one option, at least one of the first and second sanitary cubicles includes a toilet.

[0092] In one example, the first toilet stall includes a toilet; the second toilet stall may include another facility, such as a sink, urinal, table, etc.

[0093] In another example, the first toilet cubicle includes a toilet, and the second toilet cubicle also includes a toilet.

[0094] Additionally, the first or second toilet stall, or both, may include a sink. In one option, in addition to a toilet, a urinal may also be provided in one or both of the first and second toilet stalls.

[0095] exist Figures 1a to 1c In the middle, the partition wall 22 is provided with a central hinge 36, which allows the partition wall 22 to be folded outside the toilet cubicle, such as... Figure 1c As indicated.

[0096] exist Figures 1a to 1c In the arrangement shown, at the secondary position P2, the partition wall 22 is positioned in front of either the first bathroom door 16 or the second bathroom door 20. Alternatively, the partition wall 22 includes two sections 33 and 35 connected in a manner that allows it to fold along a vertical axis 36, so that it folds in front of either the first door 16 or the second door 20 at the secondary position P2.

[0097] To change from the first position to the second position, the partition wall is pulled out from the toilet unit into the passageway space in front of the first and second doors. The partition wall is either fully pulled out and then folded, or gradually folded once the first section has been pulled out. Once in the folded state, fasteners can be installed to secure the wall section attached to the toilet unit in the folded state.

[0098] In one option, when fully extended, the partition wall remains connected to the toilet fixture via its proximal end.

[0099] The term "far end" refers to the portion of the partition wall that is first removed from the bathroom location. The term "proximal end" refers to the portion of the partition wall that is last removed from the bathroom location.

[0100] Instead of placing the partition wall inside the bathroom building, this variation aims to place the partition wall outside the building by sliding it to the outside and folding it over and placing it on the outside.

[0101] In one option, at a secondary location P2, a partition wall 22 at least partially encloses the portion of the passageway area 14 located in front of the toilet fixture 10, thereby providing additional partition space 42 as an extension of the public restroom 24 (see example below).

[0102] As an example, additional partitioned spaces are provided as an extension of public restrooms for use by passengers with mobility impairments.

[0103] The term "enlarged section" refers to an additional section of space that increases the available space.

[0104] The partitioned space was set up as a private space.

[0105] Instead of placing the partition wall inside the bathroom structure, in this variation, the sliding partition wall is fixed in a way that creates extra space for PRM assistants.

[0106] A partition wall can also be called an isolation wall or a dividing wall.

[0107] In one option, the partition wall is provided with a sliding mechanism located inside the toilet compartment and pivotally supported outside the toilet compartment.

[0108] As an example, the partition wall slides out from the bathroom and locks into the adjacent module. This provides additional privacy for PRM transfers.

[0109] In the example, the bathroom door opens outwards, that is, towards the passageway area.

[0110] Alternatively, considering potential emergencies, the restroom doors are opened in a way that prevents them from opening against the flow of evacuating passengers and causing them to bump into obstructing the doors. Instead, the doors open in the direction of passenger flow, allowing passengers to close the restroom doors again.

[0111] In another example, the bathroom door is a folding door that folds inwards within the door opening.

[0112] In another example, the toilet door opens inwards, that is, towards the toilet cubicle.

[0113] The term "aisle area" refers to the space within the aircraft cabin used for the movement of passengers and crew. An aisle area typically refers to the main aisles arranged longitudinally along the aircraft, such as one or more aisles separating two or more seating areas. An aisle area also refers to lateral aisle sections that connect different main aisles or provide access to aircraft doors, galleys and lavatories, cockpit doors, and internal staircases.

[0114] Figures 2a to 2c A second example of the toilet installation 10 is shown, wherein the movable partition wall 22 is in a first state. In a secondary position P2, the partition wall 22 is arranged to extend toward a structure 38 located on the opposite side of a passageway area—for example, an entrance / exit area in the case where the toilet installation is located next to an aircraft door—such as providing an additional space 42 in front of the first or second door, separated from the adjacent passageway or seating space, which is provided as an extension of the public restroom 24.

[0115] For example, the movable partition wall 22 is connected to the building 38 via a corresponding abutment area 40 abutting against the building 38.

[0116] Figure 2a The partition wall 22, located in the main position P1, is shown.

[0117] Figure 2b The diagram shows the state during the movement of partition wall 22. Figure 2a Examples. Arrow 26 indicates the motion, such as translation, which is followed by another motion, such as pivoting.

[0118] Figure 2c The secondary position P2 is shown. Figure 2a Examples.

[0119] In order to change from the first position P1 to the second position P2, the partition wall 22 is pulled out from the toilet unit into the passageway space in front of the first and second doors. In one option, the partition wall 22 is then connected to a structure located on the opposite side of the passageway area.

[0120] In one option, the distal end of the partition wall 22 can be temporarily fixed to the building 38.

[0121] The structure can be a partition wall, kitchen, bathroom, or storage space.

[0122] The partition wall 22 moves from the primary position P1 to the secondary position P2 by translational motion.

[0123] In one option, the partition wall is set as a rigid, one-piece wall section.

[0124] In one option, the partition wall is temporarily locked to the building located on the opposite side.

[0125] In one option, when fully extended, the partition wall remains connected to the toilet fixture via its proximal end.

[0126] In one option, when fully extended, the partition wall remains connected to the toilet fixture, wherein the proximal end of the partition wall is connected to the portion of the toilet fixture located between the first and second doors.

[0127] Figures 3a to 3c A third example of the toilet fixture 10 is shown, wherein a movable partition wall 22 is in a first state. The partition wall 22 includes a main wall panel 44 and an extension section 46 located at the distal edge of the main wall panel 44, the extension section 46 for extending the effective length of the partition wall in a secondary position P2. The extension section 46 is movable from a retracted position PS to an extended position PE. In the first option, the extension section 46 is a pivoting section attached to the main panel in a manner capable of pivoting about a vertical axis 47. Arrow 45 indicates pivoting movement. In the second option, the extension section 46 is a translational section (not shown) attached to the distal front end of the main panel, which is capable of translating in a telescoping manner.

[0128] In a secondary location P2, the partition wall 22 is arranged to extend toward the building 43 located on the opposite side of the passageway area—for example, in the case of an entrance / exit area where the toilet fixtures are located next to the aircraft door—so that an additional space 42, separated from the adjacent passageway or seating space, is provided in front of the first or second door, which is provided as an extension of the public restroom 24.

[0129] Building 43 can be a partition wall, kitchen, bathroom, or storage space.

[0130] In one option, the distal end of the partition wall 22, such as the extension section 46, can be temporarily fixed to the building 43.

[0131] Figure 3a The partition wall 22, located in the main position P1, is shown.

[0132] Figure 3b The diagram shows the state during the movement of partition wall 22. Figure 3a Examples. Arrow 26 indicates the motion, such as translation, which is followed by another motion, such as pivoting.

[0133] Figure 3c The secondary position P2 is shown. Figure 3a Examples.

[0134] The term "main wall panel" refers to the larger wall section that forms a partition when in the main position.

[0135] The term "extension section" refers to a smaller section of wall used only in a secondary position. An extension section can be described as increasing the length of a partition wall.

[0136] The term "collapse position" refers to the position of the panel when it is not in use.

[0137] The term "stretch position" refers to the position of the panel when it is in use.

[0138] The term "pivot" refers to rotational motion about a vertical axis.

[0139] The term "translation" refers to linear sliding motion.

[0140] To move from the first position to the second position, the partition wall is pulled out from the toilet fixture into the passageway space in front of the first and second doors. The extension section is then either extended or retracted. In one option, the extension section is then connected to a structure located on the opposite side of the passageway area.

[0141] In the example, the pivot section is capable of pivoting from a retracted position to an extended position. In one option, a recess is provided in the main panel for at least partially accommodating the pivot section in the retracted position.

[0142] In the example, the translation segment can be translated from a retracted position to an extended position. In one option, a recess is provided in the main panel to at least partially accommodate the translation segment in the retracted position.

[0143] In one option, when fully extended, the partition wall remains connected to the toilet fixture via its proximal end.

[0144] In the example, if applicable, additional baffles are attached to the partition wall to cover a greater distance.

[0145] In another option, the partition wall includes a main wall panel and a reduction section at the distal or proximal edge of the main wall panel, the reduction section being used to reduce the effective length of the partition wall in a secondary location. The reduction section is retractable from an extended partition position to a retracted position. The reduction section is a pivoting section or a translational section; a pivoting section is attached to the main panel in a manner capable of pivoting about a vertical axis, and a translational section is attached to the distal front end of the main panel and is capable of telescoping.

[0146] Figures 4a to 4cA fourth example of a toilet unit 10 with a movable partition wall 22 is shown. A movable bridging section 48 is provided on a structure 51 located on the opposite side of a passageway area—for example, an entrance / exit area if the toilet unit is located next to an aircraft door. The bridging section 48 is movably attached to the structure 51. The bridging section 48 is movable between a parking position PP and a deployment position PD, for example, about a vertical pivot axis between the parking position PP and the deployment position PD. The second arrow 49 indicates the pivoting movement. When the partition wall 22 is in its secondary position P2 and the bridging section 48 is in its deployment position PD, the partition wall 22 is connected to the bridging section via its main panel 50.

[0147] In a secondary location P2, partition wall 22 is arranged to extend toward building 51, such that an additional space 42, separated from the adjacent aisle or seating space, is provided in front of the first or second door, which serves as an extension of public restroom 24.

[0148] Building 51 can be a partition wall, kitchen, bathroom, or storage space.

[0149] In one option, the distal end of the partition wall 22 can be temporarily fixed to the building 51 via a bridging section 48.

[0153] The term "bridging section" refers to the portion of a wall that covers the gap between a partition wall and the opposite building.

[0154] The term "parking location" refers to the location when the section is not in use.

[0155] The term "deployment location" refers to the location where the segment is used.

[0156] To change from the first position to the second position, the partition wall is pulled out from the toilet fixture into the passageway space in front of the first and second doors. The extension section is either extended or pulled out. This can happen simultaneously or independently, for example, before or after the partition wall is pulled out. In one option, the extension section and the partition wall are then connected to each other.

[0157] In one option, when fully extended, the partition wall remains connected to the toilet fixture via its proximal end.

[0158] In the example, if applicable, additional baffles are attached to adjacent modules to cover a greater distance.

[0159] Figures 5a to 5c A fifth example of a toilet installation 10 is shown, wherein a movable partition wall 22 is in a first state. The partition wall 22 includes at least two wall panel sections 52, 54 connected by a vertically hinged connector 56. In a secondary position P2, the partition wall 22 is removed from the installation and folded along the vertically hinged connector 56, and attached via its distal end to form a supplementary space partition 53, also referred to as a supplementary space portion, providing enclosure in front of the first door 16 or the second door 20. This supplementary space partition 53 is provided as an additional space portion of the toilet, i.e., the public restroom 24 is provided with an additional extension. The supplementary space partition 53 can also be referred to as a vaulted enlargement of the public restroom 24.

[0160] In a secondary location P2, a partition wall 22 is arranged such that an additional space 42, separated from the adjacent aisle or seating space, is provided in front of the first or second door, which serves as an extension of the public restroom 24.

[0161] Figure 5a The partition wall 22, located in the main position P1, is shown.

[0162] Figure 5b The diagram shows the state during the movement of partition wall 22. Figure 5a Examples. Arrow 26 indicates the motion, such as translation, which is followed by another motion, such as pivoting.

[0163] Figure 5c The secondary position P2 is shown. Figure 5a Examples.

[0164] exist Figure 5c In the example shown, one of the two doors, in this case the first door 16, is also used in conjunction with wall panel sections 52, 54 to form a vaulted enlargement.

[0165] exist Figure 5cIn another example not shown, the door is not used in conjunction with wall panel sections 52, 54 to form an arched enlargement, but the door opens into the arched enlargement (see [reference]). Figure 6c The partition wall can have two or three sections or more sections to form an extended space.

[0166] The term "wall panel section" refers to the portion of the wall that forms a partition wall.

[0167] The term "vertical hinged connector" refers to a connector that allows movement about a vertical axis.

[0168] To change from the first position to the second position, the partition wall is pulled out from the bathroom fixture into the passageway space in front of the first and second doors. The partition wall is either fully pulled out and then folded, or gradually folded once the first section has been pulled out.

[0169] In the primary location, the two wall panel sections of the partition wall are arranged in a straight line to form a straight wall panel. In the secondary location, the two wall panel sections of the partition wall are arranged at an angle or folded to form an angled or folded wall panel.

[0170] The door can be opened into the vaulted expansion to be arranged as a wall panel section parallel to the wall panel section.

[0171] Figures 6a to 6c A sixth example of a toilet fixture 10 with a movable partition wall 22 is shown. In this example, in a second position P2, the partition wall 22 is positioned in front of and adjacent to one of the first and second doors, which is hinged at its vertical lateral edge closer to the other, i.e., the door leaf is pivotally mounted on its lateral side facing the other door via a hinge. The partition wall includes two wall panel sections 60, 62, which are connected, for example, by a vertical hinge 64 and mounted to the toilet structure via a vertical hinge 66. In the second position, the proximal wall section has a horizontal width that at least spans the width of the door 20, wherein the proximal wall section is positioned in front of the door 20. The distal wall section may have a smaller or larger width. The proximal wall section is provided with a proximal lateral vertical edge connected to the toilet fixture and is held movably by the toilet fixture. The distal wall section is connected to the distal lateral vertical edge of the proximal wall section via its proximal lateral vertical edge. The distal wall section is secured to the toilet fixture via its distal lateral vertical edge.

[0172] In a secondary location P2, a partition wall 22 is arranged such that an additional space 42, separated from the adjacent aisle or seating space, is provided in front of the first or second door, which serves as an extension of the public restroom 24.

[0176] In another example, the partition wall includes three wall panel sections: a proximal wall section, a distal wall section, and an intermediate wall section disposed between the proximal wall section and the distal wall section.

[0177] In one option, when fully extended, the partition wall remains connected to the toilet fixture via its proximal end.

[0178] In the example, the partition wall slides out of the bathroom, folds, and locks into the bathroom door frame to create additional space for assistants during PRM transfers.

[0179] In another example, a partition wall slides out of the bathroom, folds, and locks into the aircraft lining to create additional space for assistants during PRM transfers.

The partition wall 22 includes at least two wall panel sections 68, 70 connected by a vertically hinged connector 74. In a secondary position P2, the partition wall 22 is removed from the installation and folded along the vertically hinged connector and attached via its distal end to a cabin bulkhead structure 72 or aircraft door located on the side of a first or second toilet, thereby providing an additional space adjacent to the first or second door, which serves as an extension of a public toilet 24.

[0181] In the example, instead of cabin bulkhead structure 72 or aircraft door, a structure is provided, and partition wall 22 is folded to abut the structure, which can be a partition wall, kitchen, toilet or storage space.

[0182] In a secondary location P2, a partition wall 22 is arranged such that an additional space 42, separated from the adjacent aisle or seating space, is provided in front of the first or second door, which serves as an extension of the public restroom 24.

[0183] Door 20 can be opened into the additional space 42.

In a secondary position P2, the partition wall 22 is arranged to extend from the toilet fixture 10 to a structure 82 located on the opposite side of the passageway area. To achieve the secondary position P2, in a fully extended state, the partition wall 22 is movable via its proximal edge from a position between the first door 16 and the second door 20 toward a position opposite to the first and second doors. In the secondary position P2, the partition wall 22 is connected via its proximal end to a portion of the toilet fixture 10 arranged on the lateral side of the first or second door, such that an expanded additional space is provided in front of the first door 16 and the second door 20, separated from the adjacent passageway or seating space, which is provided as an extension of the public restroom 24. The partition wall 22 has a first panel 78 and a second panel 80 that bridge the structure 82, such as an edge or side of the structure 82. The two panels are connected by a hinge 84.

[0191] In a secondary location P2, a partition wall 22 is arranged such that an additional space 42, separated from the adjacent aisle or seating space, is provided in front of the first or second door, which serves as an extension of the public restroom 24.

[0192] Building 43 can be a partition wall, kitchen, bathroom, or storage space.

[0195] Figure 8c The secondary position P2 is shown. Figure 8a Examples.

[0196] The lateral side of the first or second door refers to the position located on the side of the door opposite to the position between the two doors.

[0197] In one option, when fully extended, the partition wall remains connected to the toilet fixture, wherein the proximal end of the partition wall is connected to the portion of the toilet fixture located between the first and second doors.

[0198] Instead of placing the partition wall inside the bathroom structure, in this variation, the sliding partition wall is removed and fixed in a way that creates additional space for PRM assistants.

[0199] In the example, the partition wall slides out of the bathroom, folds, and locks into the aircraft liner to create additional space for assistants during PRM transfers.

[0200] In an option not shown, partition wall 22 includes an extendable enclosed section at its upper edge; the enclosed section can be removed in a secondary location to enclose additional partition space upwards.

[0201] Additional partition space can be provided as a rigid baffle bridging the gap between the partition wall and the toilet compartment shell structure, or as a soft fabric covering section spanning across the partition wall and toilet compartment shell structure.

[0202] Figure 9a A ninth example of a toilet installation is shown, in which the movable partition wall 22 is in the first state, i.e., in the main position P1.

[0203] Figure 9bAn example of the second state is shown, which provides an expanded section of the public health toilet. Figure 6a / Figure 6b A similar example is provided, in which the movable partition 22 is in a secondary position P2. The movable partition 22 includes two panels 88, 90 connected by hinges. The door leaf of the door 20 can be opened into the space provided by the movable partition 22.

The cabin 100 also includes at least one aisle area 104 for allowing passengers to move within the cabin. The cabin 100 also includes at least one toilet structure.

[0206] A toilet building is a structure that provides sanitation services. A toilet building contains one or more toilet cubicles. In this example, at least two toilet cubicles are provided. A toilet building may also be referred to as a toilet module, toilet unit, or toilet.

[0207] In one option, the entrance area 105 is positioned adjacent to the aircraft door 107, and includes an entrance passageway area 104'. Access to the first sanitary compartment 12 and the second sanitary compartment 18 is possible from the entrance passageway area. As an example, the first toilet structure 106' is located at the aft end, for example, near the bulkhead.

[0208] In one option, at least one passageway area 104 includes at least one longitudinally arranged passageway 104'. Access to the first toilet cubicle 12 and the second toilet cubicle 18 is possible from the passageway 104'. As another example, a second toilet structure 106" is arranged along the passageway. At least one toilet structure 106 includes at least one example of a toilet fixture 10 according to one of the examples described above.

[0209] The term "passenger seating area" refers to the section of the aircraft cabin where passengers are seated.

[0210] The term "aisle area" refers to the section of the cabin that serves as a passageway for movement within the aircraft.

[0211] The term "toilet building" refers to buildings and other structures in the cabin that provide lavatory facilities on an aircraft.

[0212] Figure 10 An example of an aircraft 150 is also shown, which includes a fuselage 152 and a cabin space 154 disposed within the fuselage 152. In a first option, at least one lavatory device according to one of the examples described above is provided in the cabin space. In a second option, a cabin according to one of the examples described above is additionally or alternatively provided in the cabin space.

[0213] Aspect II: Figure 11a / Figure 11b An example of a partition wall 510 is schematically shown for use in an aircraft lavatory within the cabin of an aircraft. The partition wall 510 includes a main wall panel 512, a secondary wall panel 514, and mounting components 516. The main wall panel 512 is configured to be fixedly disposed between a first lavatory L11 and a second lavatory L12 in a dual-lavatory arrangement. The secondary wall panel 514 is configured to be removably disposed between the first lavatory L11 and the second lavatory L12, such that in an attached first position P11, the secondary wall panel 514 and the main wall panel 512 provide a separation between the first lavatory L11 and the second lavatory L12. The secondary wall panel 514 is movable to a detached second position P12 outside the lavatory arrangement, in which the separation between the first lavatory L11 and the second lavatory L12 is eliminated. The mounting assembly 516 is configured to removably mount the secondary wall panel 514, which is in the first position P11, to at least one of the following: a bathroom enclosure and a main wall panel 512.

[0214] Figure 11a / Figure 11b A horizontal cross-section of the partition wall 510 is shown. For better understanding, a toilet unit with a first toilet L11 and a second toilet L12 is also shown.

[0215] Figure 11a The secondary wall panel 514 is shown in the first attached position P11.

[0216] Figure 11b The secondary wall panel 514 is shown in a disassembled second position P12 outside the toilet unit; the partition between adjacent toilets is removed, and an enlarged public toilet LC is provided. Additionally, the intermediate position of the secondary wall panel 514 during its free movement from the first position P11 to the second position P12 is also shown in dashed lines.

[0217] The term "main wall panel" refers to the portion of partition wall 510 that is constructed to be retained. Main wall panel 512 may also be referred to as main wall component, fixed wall panel, or fixed wall portion.

[0218] The term "secondary wall panel" refers to the portion of partition wall 510 that is temporarily removed. Secondary wall panel 514 may also be referred to as a movable wall component, movable wall panel, or movable wall section.

[0219] The term "mounting assembly" refers to the hardware and connecting parts arranged for installing and releasing a secondary wall panel. Mounting assembly 516 may also be referred to as a removable mounting assembly. Mounting assembly 516 includes latches, bolts, screws, or other removable or releasable mounting elements to hold the secondary wall panel 514 in a first position P11.

[0220] The partition wall 510 can also be referred to as a partition wall or an isolation wall. The partition wall 510 can also be referred to as a movable bifunctional partition wall.

[0221] Secondary wall panel 514 provides a removable partition wall for bathroom structures.

[0222] exist Figure 11a and Figure 11b In one example, mounting component 516 is configured to removably attach the secondary wall panel 514 in the second position P12 to at least one of the following: the cabin-facing side of the lavatory enclosure and another structure within the cabin (see also...). Figures 16a to 16c ).

[0223] Therefore, the secondary wall panel 514 partially encloses or at least separates the additional space in front of the toilet for use by the PRM when using the toilet.

[0224] Furthermore, in the example, mounting assembly 516 is configured to removably connect one end of the secondary wall panel 514 to the cabin-facing side of the toilet enclosure, or to another structure on the other side of the passageway area in front of the toilet within the cabin. Additionally, mounting assembly 516 is configured to removably connect the other end of the secondary wall panel 514 to the other side, i.e., to the cabin-facing side of the structure or toilet enclosure.

[0225] The connection between the secondary wall panel 514 and the bathroom enclosure can be directly connected to the outside of the bathroom enclosure, or indirectly connected via a bridging component, such as an open bathroom door.

[0226] In one option, the secondary wall panel 514 is symmetrical along a vertical axis. The term "symmetrical" refers to having similar lateral connections and mounting joints. In another option, the term "symmetrical" refers to similar connection joints for installation in the first position. This allows the secondary wall panel 514 to be installed in either orientation and facilitates operation when transforming the toilet from a second case—e.g., an enlarged public toilet, with or without a partition space in front of the door opening—to a first case, e.g., a double toilet use. In another option, the term "symmetrical" also refers to similar connection joints for installation in the second position.

[0227] Figure 12a Another example of a partition wall 510 in the first position P11 is shown. The secondary wall panel 514 includes a first panel segment 520 and a second panel segment 522. The first panel segment 520 and the second panel segment 522 are movably connected to each other.

[0228] Figure 12b It shows Figure 12a In the example, the first panel segment 520 and the second panel segment 522 of the secondary wall panel 514 are in the second position P12. Additionally, the intermediate position of the secondary wall panel 514 during its free movement from the first position P11 to the second position P12 is also shown in dashed lines.

[0229] The term "panel segment" refers to the following portions of the secondary wall panel 514: these portions form a removable portion of the partition wall 510. In one option, more than two, i.e., three, four, five or more panel segments are provided.

[0230] In the example, the secondary wall panel 514 includes three or more panel segments that are attached to each other, for example, in a pivotable manner.

[0231] In the first option, the first panel segment 520 and the second panel segment 522 are permanently attached to each other when the secondary wall panel 514 moves from the first position P11 to the second position P12, and the first panel segment 520 and the second panel segment 522 are permanently attached to each other when the secondary wall panel 514 moves from the second position P12 to the first position P11.

[0232] In the example, the first panel segment 520 and the second panel segment 522 are connected in a foldable manner, for example, by means of a vertically hinged connector.

[0233] The term "vertical hinged connector" refers to a connector that allows movement about a vertical axis when the secondary wall panel 514 is arranged vertically, such as in the first position P11.

[0234] In the second option, the first panel segment 520 and the second panel segment 522 are removably attached to each other when the secondary wall panel 514 moves from the first position P11 to the second position P12, and the first panel segment 520 and the second panel segment 522 are removably attached to each other when the secondary wall panel 514 moves from the second position P12 to the first position P11, and two or more panel segments are processed separately.

[0235] In the example, the first panel segment 520 and the second panel segment 522 are releasably connected along the vertical axis.

[0236] According to the example, the first panel section 520 and the second panel section 522 are symmetrical along the vertical axis of the vertical hinge.

[0237] The term "symmetry" refers to having similar dimensions to fold onto each other. In one option, the term "symmetry" refers to similar connecting elements for mounting in a first position. In another option, the term "symmetry" also refers to similar connecting elements for mounting in a second position.

[0238] The term "vertical axis" refers to a virtual line that can coincide with the pivot axis / rotation axis.

[0239] Figure 13 and Figure 14 A horizontal cross-section or plan view of an example of a lavatory device 600 for an aircraft cabin is shown. The device 600 includes a first lavatory compartment 602 and a second lavatory compartment 604. Access to the first lavatory compartment 602 is possible from a passageway area 606. Access to the second lavatory compartment 604 is also possible from a passageway area 606. An example of a partition wall 510, according to one example of the above example, is arranged between the first lavatory compartment 602 and the second lavatory compartment 604. In a first position P11, the partition wall 510 separates the first lavatory compartment 602 from the second lavatory compartment 604. In a second position P12, a secondary wall panel is moved to the exterior of the first lavatory compartment 602 and the second lavatory compartment 604. In the second position P12, the first lavatory compartment 602 and the second lavatory compartment 604 provide an enlarged public lavatory 608.

[0240] As an example, both bathrooms are equipped with toilets and sinks. However, other interior features are also included.

[0241] exist Figure 13 In the example, the secondary wall panel 514 is configured as a single panel segment. The second location P12 of the secondary wall panel 514 on the exterior of the bathroom is shown in dashed lines.

[0242] exist Figure 14In the example, the secondary wall panel 514 is set as a double-panel section. The second location P12 of the secondary wall panel 514 on the exterior of the bathroom is also shown in dashed lines.

[0243] The toilet unit 600 serves as a dual-function toilet. In the first case, the toilet unit 600 provides a dual toilet for the exclusive use of two passengers. In the second case, the toilet unit 600 provides a single toilet for the exclusive use of only one passenger, such as a single toilet for a passenger / person with mobility impairments.

[0244] In one option, the two toilet cubicles are arranged such that the toilets are displaced relative to each other in terms of their distance from the entrance side.

[0245] In the example, at least one aisle area 606 includes at least one longitudinally arranged aisle. Access to the first and second sanitary compartments is possible from the aisle.

[0246] In the example, the entrance area is positioned next to the aircraft door (see also...). Figures 16a to 16c The entrance area includes the entrance passageway area. It is possible to access the first and second toilet cubicles from the entrance passageway area.

[0247] As an example, the expanded public restrooms were designed for use by passengers with mobility impairments.

[0248] The term "toilet cubicle" refers to an enclosed space containing toilet fixtures such as a toilet, urinal, sink, mirror, or trash can. Toilet cubicles can also be called restrooms, washrooms, lavatories, or passenger service rooms. They can also be referred to as toilet spaces.

[0249] The term "aisle area" refers to the following parts of the aircraft cabin: these parts are designed for the passage of passengers and crew, the movement of passengers and crew on board, and the movement of service units such as trolleys used for in-flight service. Aisle areas are typically adjacent to seating areas with passenger seats. Aisle areas can also be referred to as aisle layout structures.

[0250] The term "partition wall" refers to a wall that separates the first and second toilet cubicles, i.e., the first and second toilet spaces. When first used, the partition wall acts as a dividing structure, and when removed, it "acts" as an integrator or connector for combining the two smaller toilet spaces with an expanded common space. Therefore, a partition wall is a dual-function toilet wall. The term "dual-function" means that the wall can be moved between two locations to achieve two different purposes.

[0251] The term "primary position" refers to the main or primary location for use in the bathroom. Primary position P11 can also be referred to as the dual-toilet location.

[0252] The term "secondary position" refers to a secondary or auxiliary position for use in the toilet. Secondary position P12 can also be referred to as the PRM toilet usage position.

[0253] The term "public toilet" refers to an enlarged toilet space where two toilets are enclosed, but only one toilet is actually usable.

[0254] The term "exterior of a toilet fixture" refers to the removal of a secondary wall panel from the interior of the toilet fixture and its placement in front of the fixture's housing.

[0255] In the second position P12, the dual-function partition wall is moved to a position outside the toilet unit 600.

[0256] The expanded public restrooms are designed for use by passengers with mobility impairments (PRMs), such as wheelchair users. For PRMs to use the restrooms, they must be able to transfer from their wheelchairs to the toilet seat and back to the wheelchair. In addition to extra handles and grips throughout the cabin, more space must be provided for this usage scenario. Further space for assistive personnel may also be needed for PRMs to use the restrooms.

[0257] To save space, the toilet cubicles were designed for standard use, allowing for a layout with minimal footprint. However, these cubicles were too small for use by PRMs. To provide larger cubicles suitable for PRM use, two cubicles were combined by removing the partition wall. Instead of folding the wall section and storing it inside the toilet, the wall was moved out of the cubicle and fixed in a different location. Therefore, the usable space inside the cubicle was maximized.

[0258] The expanded public restrooms allow for wheelchair access. Furthermore, the expanded public restrooms also provide space for assistance personnel.

[0259] In one option, at least one of the first and second sanitary cubicles includes a toilet.

[0260] In one example, the first toilet stall includes a toilet; the second toilet stall may include another facility, such as a sink, urinal, table, etc.

[0261] In another example, the first toilet cubicle includes a toilet, and the second toilet cubicle also includes a toilet.

[0262] Additionally, the first or second toilet stall, or both, may include a sink. In one option, in addition to a toilet, a urinal may also be provided in one or both of the first and second toilet stalls.

[0263] Figure 15 An example of kit 550 is schematically shown, which is used to convert a toilet unit with two adjacent toilets into an enlarged toilet suitable for PRM. Kit 550 includes an example of a partition wall 510 according to one of the examples above, which is configured to replace the existing rigid partition wall between the two adjacent toilets. In addition, kit 550 includes a main fitting 552 for securely mounting a main wall panel 512 inside the toilet unit.

[0264] The term "main components" refers to the arrangement of hardware and connecting joints that provide for the installation of the main wall panels.

[0265] In one option, kit 550 is configured to include a secondary wall panel 514, while the primary wall panel is provided by an existing panel section of the bathroom partition wall.

[0266] Kit 550 allows for the replacement of solid walls and the transformation of the toilet into a larger one, at least temporarily, to make room for the assistive PRM to move from a wheelchair to the toilet seat. Kit 550 can be provided as a retrofit upgrade or modification during cabin installation.

[0267] Therefore, the removable partition wall can be completely removed from the bathroom shell structure and moved outside the bathroom. The movable wall panel acts as a visual barrier outside the bathroom. This visual barrier provides additional privacy in front of the bathroom structure.

[0268] exist Figure 15 In one example, the mounting assembly 516 of the partition wall 510 includes at least one retaining device 554 configured to removably mount the secondary wall panel 514 in the second position P12 to the cabin-facing side of the toilet enclosure and / or another structure within the cabin.

[0269] The term "retaining device" refers to the arrangement of hardware and connecting joints that provide movable mounting for secondary wall panels.

[0270] The retaining device assembly includes, for example, latches, bolts, screws, or other removable or releasable mounting elements to hold the secondary wall panel in a second position. In one example, the retaining device is configured to attach to the secondary wall panel 514. In another example, the retaining device is configured to attach to the cabin-facing side of the lavatory enclosure and / or another structure within the cabin. In yet another example, the retaining device is configured to attach to the secondary wall panel 514 and a cabin structure, which takes the form of the cabin-facing side of the lavatory enclosure and / or another structure within the cabin.

[0271] Figure 16a , Figure 16b and Figure 16c Another example of a toilet unit 600 is shown.

[0272] exist Figure 16a In this configuration, secondary wall panels 514 are arranged on the exterior of the toilet cubicle in the passageway area in front of the toilet. Figure 16b In this case, secondary wall panels 514 are temporarily attached to a building or other fixed structure on the other side of the passageway area. Figure 16c In this configuration, the secondary wall panel 514 is also temporarily attached to the building or other fixed structure, while the toilet door opens and connects to the secondary wall section 514 via its free end. The foyer is enclosed, thus providing additional space for toilet users, such as PRM passengers.

[0273] In one option, in the fully removed state, the partition wall is not connected to the cabin-facing side and / or structure of the lavatory enclosure before being removably installed to the cabin-facing side and / or structure of the lavatory enclosure.

[0274] According to the example, one can enter the first toilet stall 602 from the corridor area through the first door 610, and can enter the second toilet stall 604 from the corridor area through the second door 612. In the second position P12, the secondary wall panel 514 is arranged to extend from the toilet stall 602 toward the structure 614 located on the opposite side of the corridor area 606, such that an additional space 616 separated from the adjacent corridor or seating space is provided in front of the first or second door, which is provided as an extension of the public toilet.

[0275] The extended section provides an entryway for the enlarged bathroom space.

[0276] In the example, the fitting assembly 516 is configured to removably attach the secondary wall panel 514 in the second position P12 to at least one of the following: the cabin-facing side of the toilet enclosure and another structure within the cabin, such that an additional space 616 separated from the adjacent aisle or seating space is provided in front of the first door 610 or the second door 612, which is provided as an extension of the public restroom.

[0277] The term "removably secured" refers to the secondary wall panel 514 being installed in a releasable manner so that the secondary wall panel 514 can be removed, that is, the secondary wall panel 514 is moved from the second position P12 back to the first position P11.

[0278] The term "cabin-facing side" refers to the outer side of the lavatory enclosure that faces into the cabin interior, such as the aisle area adjacent to the lavatory unit 600. The aisle area or section can be a section extending laterally to the flight direction, for example, a section connecting a main aisle extending in the flight direction to an aircraft door. Alternatively, the aisle area or section can be a section extending along the flight direction.

[0279] The term "another structure" refers to another structure located within the cabin. This other structure can be a separate lavatory, galley structure, storage space, partition wall, or wall behind a row of seats, etc.

[0280] The term "door" refers to a movable part that allows access to the sanitary cubicle.

[0281] As an example, aisle area 606 is located next to aircraft door 618. Therefore, aisle area 606 also serves as an entrance / exit area. However, during flight, aisle area 606 can be used for different purposes.

[0282] As an example, the secondary wall panel 514 can be connected to the cabin-facing side of the lavatory enclosure and another structure within the cabin via at least one retaining device of the mounting assembly 516 of the partition wall 510. The retaining device is configured to removably mount the secondary wall panel 514, in the second position P12, to the cabin-facing side of the lavatory enclosure and another structure within the cabin.

[0283] The secondary wall panel 514 at least partially encloses the portion of the passageway area 606 located in front of the toilet fixture 600, thereby providing additional partition space as an extension of the public restroom.

[0284] As an example, additional partitioned spaces are provided as extended portions of public restrooms for use by passengers with mobility impairments.

[0285] The term "enlarged section" refers to an additional section of space that increases the available space.

[0286] The partitioned spaces are provided as private spaces.

[0287] In order to change from the first position P11 to the second position P12, the partition wall 510 is partially removed from the toilet unit 600 into the passageway space in front of the first and second doors. The movable portion of the partition wall 510 is completely removed and then folded or gradually folded and then removed, and then at least partially unfolded.

[0288] In the first position P11, the two wall panels of the partition wall 510 are arranged in a straight line to form a straight wall panel. In the second position P12, the two wall panels of the partition wall 510 are arranged in an inclined or folded manner to form an inclined or folded panel.

[0289] In the second position P12, the partition wall 510 is arranged to extend from the toilet unit 600 to a structure located on the opposite side of the passageway area. To reach the second position P12, the secondary wall panel 514 can be moved to a position outside the toilet in a completely removed state. In the second position P12, the secondary wall panel 514 is connected to the structure on the other side of the passageway area via one lateral vertical side edge, and to a portion of the lateral side of the toilet unit 600 arranged at the first or second door via another lateral vertical side edge, such that an extended additional space separated from the adjacent passageway or seating space is provided in front of the first and second doors, which is provided as an extension of the public toilet.

[0290] The lateral side of the first or second door refers to the position of the door on the side opposite to the position between the two doors.

[0291] In addition to providing public, expanded restroom space, the removed wall panels were fixed in a way that created additional space for PRM assistants in front of the restrooms, rather than having the movable wall panels of the partition walls stored inside the restroom building.

[0292] The structure can be a partition wall, kitchen, bathroom, or storage space.

[0293] In one option, the secondary wall panel 514 is temporarily locked to the building located on the opposite side.

[0294] The term "aisle area" refers to the space within the aircraft cabin used for the movement of passengers and crew. An aisle area typically refers to the main aisles arranged longitudinally along the aircraft, such as one or more aisles separating two or more seating areas. An aisle area also refers to aisle sections in the lateral direction that connect different main aisles or provide access to aircraft doors, galleys and lavatories, cockpit doors, and internal staircases.

[0295] In the example, the bathroom door opens outwards, that is, towards the passageway area.

[0296] As an alternative, considering potential emergencies, the restroom door is opened in a way that prevents it from opening against the flow of evacuating passengers, causing them to bump into the obstructing door. Instead, the door opens in the direction of passenger flow, allowing them to close the restroom door again.

[0297] In another example, the bathroom door is a folding door that folds inwards within the door opening.

[0298] In another example, the toilet door opens inwards, that is, towards the toilet cubicle.

[0299] As an option, Figure 16c As shown at the second position P12, the secondary wall panel 514 is attached to the open distal edge 620 of the first or second door.

[0300] The term "far edge" refers to the edge of a door opposite to the edge that is connected to the door frame by hinges. The far edge is the free end or edge of a door when it is open.

[0301] In one option, the secondary wall panel 514 is attached to the distal edge of the opening of the bathroom door, which is further away from the external unit structure. This door, further away from the external unit structure, may be referred to as the first bathroom door. The bathroom door, closer to the external unit structure, may be referred to as the second bathroom door. The second bathroom door can be opened such that it closes the opening of the first door.

[0302] The door can be hinged to the outer corner of the bathroom.

[0303] In one option, the door is hinged to the central section of the bathroom between the two openings of the two bathroom doors.

[0304] Alternatively, additional curtain sections can be provided to enclose the area above the open door and above the secondary wall panel 514.

[0305] Figure 17An example of a cabin 700 for an aircraft is shown. The cabin 700 includes at least one passenger seating area 702 having a plurality of passenger seats.
