Description

TECHNICAL FIELD

[0001] The invention relates to a toilet module for a vehicle and to a vehicle with a vehicle cabin and at least one toilet module. BACKGROUND OF THE INVENTION

[0002] A key objective in the design of passenger cabins in modes of transport is often to maximize the available number of seats for passengers, which is limited by, among other things, the number of required seats for crew members, mandatory safety features, utility facilities, and lavatories. The ratio of the number of passenger seats to other facilities in passenger cabins is a factor that determines the economic viability of an aircraft in scheduled service. In addition to official regulations for type and operational certification of modes of transport, customer requirements, such as customized special installations by the mode of transport operator, must also be taken into account when selecting seat sizes, seat pitches, utility facilities, and lavatories.

[0003] Aircraft kitchens are generally virtually unchangeable in size due to the amount of food carried and the necessary capacity for heating equipment. DE 10 2009 034 406 A1, however, shows an expandable toilet module whose external dimensions can be increased during flight. However, this can only be achieved in a door area where the toilet module can be extended.

[0004] DE 43 00 877 A1 and US 5 474 260 A show an aircraft with a number of service facilities and toilets.

[0005] US 2008 / 0 265 092 A1 describes an accessible aircraft lavatory comprising a wheelchair area, a toilet assembly adjacent to the wheelchair area and oriented at a non-zero angle thereto, and a sink assembly adjacent to the toilet assembly. The sink assembly includes a basin positioned at a predetermined height and a predetermined lateral distance relative to the toilet seat, wherein the predetermined height and the predetermined distance are selected such that the sink assembly is within arm's reach of a passenger sitting on the toilet seat (for example, a male passenger of the 95th percentile). Additional amenities such as mirrors, toilet paper, tissues, and the like may also be similarly positioned.

[0006] DE 20 2005 015 729 U1 describes a cubicle comprising a rear wall with vertical joints that are integrally connected to the side walls of the cubicle. The rear wall and the side walls are provided with a bead that runs horizontally to the cubicle. The hand basin and waste bin are arranged side by side and connected by a one-piece neck. A toilet seat is arranged in an interior chamber, and a curved strike plate is provided with a curved door.

[0007] US 2004 / 0 163 170 A1 describes dual-purpose toilet units. A toilet unit comprises a first section, a second section, and a partition separating the first and second sections. The first section comprises a toilet, and the second section comprises at least one urinal and one washbasin. The multi-purpose toilet can be constructed as a unit mountable in a vehicle, for example, an aircraft.

[0008] US 6 079 669 A describes a pull-out toilet with two swivel joints for use in confined spaces, such as in an aircraft.

[0009] US 7 364 119 B2 describes a compartment in a passenger aircraft that is equipped with functional elements that can be adapted for different uses or purposes.

[0010] SUMMARY OF THE INVENTION The object of the invention is to propose a toilet module for integration into a vehicle cabin which is as space-saving as possible and which essentially has the smallest possible width while maintaining the same overall depth as possible compared to conventional toilet modules in order to optimize the space available in the vehicle cabin.

[0011] The object is achieved by a toilet module having the features of independent claim 1. Advantageous further developments and embodiments can be found in the subclaims and the following description.

[0012] A toilet module for a vehicle has a front wall, a first useful wall and at least one second useful wall, wherein the first useful wall is arranged opposite the front wall and carries a toilet unit, wherein the at least one second useful wall runs between the first useful wall and the front wall and encloses a right angle with the front wall, wherein the toilet unit has a longitudinal axis which encloses an angle with the at least one second useful wall which is greater than 0°.

[0013] The designations of the individual walls of the housing of the toilet module according to the invention are chosen according to their function. While a front wall acts as a visual boundary separating the toilet module from a passenger cabin and allowing access through an opening, the first utility wall and the at least one second utility wall are primarily necessary to fulfill the function of the toilet module, particularly through their load-bearing function.

[0014] The toilet module is designed to be installed transversely or longitudinally within a vehicle cabin between other modules or between rows of seats. The access opening in the front wall is accessible from an aisle within the vehicle, so the front wall should be aligned either parallel to the aisle or, if the toilet module is to be installed in the rear area of ​​the vehicle, perpendicular to it.

[0015] A toilet unit can be understood, in particular, as a toilet bowl or urinal, on which a frame, a housing, an adapter, or a mounting flange is arranged for attachment to a wall. The toilet unit is equipped with the necessary functional devices, such as water supply and wastewater connections, locking sensors, operating elements, and possibly cladding elements. The toilet unit can generally have a base facing away from a user side, which can be attached to the first usable wall.

[0016] The first usable wall is the wall that supports the toilet unit. The user of the toilet module according to the invention enters the space enclosed by the housing through the access opening and, upon entry, is directly facing the toilet unit on the opposite side. The special feature of the toilet module is that the longitudinal axis of the toilet unit is not aligned perpendicular or parallel to one of the at least one second usable wall, as is usual in the prior art, but rather diagonally to it at a certain angle. The user therefore approaches a toilet unit that is not directed straight towards them, but rather displays an asymmetry. This allows additional installation space to be created on one side of the toilet unit, allowing for easier accommodation and use of a washbasin or other fixture.At the same time, this allows for a reduction in the width of the toilet module, as the space required for comfortable use is available even with a smaller width. This allows the toilet module according to the invention to be significantly narrower than conventional toilet modules, thus allowing for an increase in the space available within the vehicle cabin without having to forego necessary amenities or comfort.

[0017] In an advantageous embodiment, a base of the toilet unit is arranged centrally on the first utility wall. The base is thus vertically centered on the first utility wall.

[0018] In a simple embodiment, the at least one second utility wall is substantially flat and has a plane of extension extending from the base to a top surface of the toilet module. In this simple embodiment, there are no bulges or indentations.

[0019] In an advantageous embodiment, the angle between the longitudinal axis of the toilet unit and the second utility wall ranges from 15° to 45°. A significant increase in space within the toilet module can be achieved starting at an angle of approximately 15°. Angles above 45° have little impact on the available installation space, but can limit the comfort of using the toilet unit.

[0020] In an advantageous embodiment, the first utility wall has a curved shape that corresponds, at least in sections, to a curved fuselage wall of a vehicle. This particularly applies to the fuselage of an aircraft, which frequently has a cylindrical or elliptical shape, or any combination thereof. If the toilet module according to the invention is integrated transversely between rows of passenger seats, next to, or within a module arrangement, the first utility wall can have a curved shape that allows the toilet module to extend from an aisle in the vehicle cabin directly to the fuselage wall. The first utility wall thus nestles at least partially against the fuselage wall and allows optimal use of space.Arranging the toilet unit against this curved first utility wall, with sufficient extension along the longitudinal axis, allows unrestricted use of the toilet unit while sitting, while still leaving sufficient space between the toilet unit and the front wall for standing. When using the toilet unit while seated, the user's knees point away from the second utility wall, so that a sink or similar device located there is not perceived as a disturbance.

[0021] According to the invention, the toilet module has an upper side, wherein at least one second usable wall on the upper side has a cutout, to which a storage compartment is connected, which extends outwards from the housing of the toilet module. Valuable storage space can therefore be provided outside the toilet module in an area of ​​the vehicle cabin that would not be used by passengers sitting adjacent to the toilet module, without taking up installation space within the toilet module. If the toilet module according to the invention is arranged, for example, to the side of an aisle in a vehicle cabin, storage compartments are often located adjacent to it above the passenger seats. These are often only available in standardized dimensions, as they must be attached between structural components, such as fuselage frames, which are distributed equidistantly over the length of the vehicle fuselage and therefore specify a certain transverse extent of the storage compartments.If the toilet module does not exactly match the width of such a storage compartment with specified dimensions or if it is not located directly next to the relevant structural components used to attach storage compartments, an area between the top of the toilet module and the next storage compartment must be bridged. This is often done with a panel that serves a purely visual function. The toilet module according to the invention, with the storage compartment adjoining it to the outside, can make this space useful. The storage compartment can be dimensioned in such a way that it can be additionally covered with a panel; alternatively, the opening in the at least one second usable wall can also be dimensioned in such a way that the adjoining storage compartment can take on the function of a panel. For example, this storage compartment can be used to store spare towels or other objects.

[0022] In an advantageous embodiment, the toilet module has two second utility walls, which are opposite each other and each have a cutout on their upper side, into which a storage compartment extends outwards. This allows for maximum storage space without having to increase the external dimensions of the toilet module.

[0023] In an advantageous embodiment, a washbasin is arranged on a second usable wall of the at least one second usable wall in an area facing the front wall. This creates a complete toilet module, with the toilet unit and the washbasin being spaced as far apart as possible to fully utilize the available installation space.

[0024] In an advantageous embodiment, the access opening is narrower than the actual front wall and is located in a section of the front wall facing away from the washbasin. The access opening therefore does not occupy the entire width of the front wall. Due to the asymmetrical arrangement, a usable corner is located between the respective second utility wall and the front wall, into which the washbasin extends. The front wall designed in this way allows for a significant reduction in the required installation space.

[0025] In an advantageous embodiment, the washbasin extends into an area of ​​the front wall facing away from the access opening. The washbasin thus occupies an area of ​​the front wall that has no function for access to the toilet module. The washbasin can also extend minimally into an area in front of the access opening, as long as this does not impede access to the toilet module. The transition from the access opening to the widest point of the washbasin can preferably be designed with a curved shape for a visually appealing appearance and to avoid impact hazards.

[0026] In an advantageous embodiment, the washbasin has a longitudinal extension, wherein the longitudinal extension of the washbasin runs essentially parallel to the longitudinal extension axis of the toilet unit. If the washbasin has an ellipsoid-shaped washbasin, for example, the available width can be greater than the necessary installation depth in the washbasin. In this example, the longitudinal extension could coincide with an axis that lies along the greatest extent of the washbasin or of the washbasin accommodating the washbasin. In addition, the washbasin extends along the relevant second utility wall. For example, a front edge section of the washbasin arranged in the area of ​​the washbasin and protruding into the room, an extension axis of the washbasin, or another distinctive feature can form the longitudinal extension of the washbasin.The parallel alignment of the two longitudinal extensions allows for particularly good use of space and a particularly spacious feeling. A person standing at the washbasin is obstructed as little as possible by the toilet unit, and the space between the toilet unit and the washbasin can be maintained at a largely constant width.

[0027] In an advantageous embodiment, a vertical boundary surface for a storage space extends above the toilet unit up to the first usable wall. The verticality refers to a perpendicular alignment to the base area enclosed by the housing. With a curved first usable wall, as mentioned above, the toilet unit projects far enough into the toilet module that a person can sit upright on it and stand upright in front of it. This creates an area behind the toilet unit up to the first usable wall, which can then be used if a boundary surface is arranged in a vertical alignment. A storage space thus formed is arranged in the toilet module in such a way that a user can use the toilet unit in the conventional way without being disturbed by the storage space.If the first utility wall is not curved, it is particularly preferred that the toilet unit be offset or extended far enough from the first utility wall into the toilet module that the vertical boundary surface can extend completely or largely over it. When installed, the boundary surface is visually perceived as the rear wall of the toilet module.

[0028] In an advantageous embodiment, the first utility wall is aligned parallel to the front wall. Thus, the toilet module according to the invention can have a rectangular cross-section, so that the toilet module can be arranged, for example, in a rear section or in a cylindrical area to the side of an aisle in a vehicle cabin.

[0029] In an equally advantageous embodiment, the first usable wall can also run at an angle to the front wall, so that the resulting toilet module could be arranged in the tail cone of an aircraft, where the available installation depth decreases as it approaches a pressure section bordering the rear of the aircraft cabin. It would also be conceivable to arrange the toilet unit in a deeper area of ​​the toilet module to further enhance the sense of space.

[0030] If consideration is given to using toilet modules with non-rectangular arrangements of the front wall and the second utility wall, the toilet module must be modified such that the front wall has an access opening facing away from one of the at least one second utility wall, with a washbasin arranged in a region of the second utility wall facing the front wall. The washbasin should extend toward the front wall, while the toilet unit has an extension axis facing away from the washbasin.

[0031] In an advantageous embodiment, the second utility wall, toward which the toilet unit faces, has a bulge on its underside. The bulge preferably extends from the base area of ​​the toilet module to a height that exceeds the height of the toilet unit and can be approximately at the height of a washbasin that can be attached to one of the second utility walls. The bulge can provide more installation space on the inside of the toilet module and, on the outside, allows the backrests of passenger seats that are arranged directly adjacent to the toilet module to be swung in. The bulge is preferably located on the second utility wall toward which the toilet unit faces. The other second utility wall, which lies opposite the second utility wall with the bulge, can be flat or essentially flat in a simple variant.

[0032] In an advantageous embodiment, the respective other second utility wall has a recess, which is preferably designed to correspond to the bulge of the opposite second utility wall. Since a washbasin or other fixture is usually arranged there that does not require excessive installation space on its underside, the recess can be provided without restricting the installation space. This design also allows for the staggering of several toilet modules according to the invention, in which two second utility walls nestle against one another, with each bulge extending into a recess.A first toilet module can, for example, have a flat second utility wall and a second utility wall with a bulge, while a subsequent second toilet module has a recess on a second utility wall and a bulge on the opposite second utility wall, allowing the second toilet module to fit flush against the first toilet module. In addition to staggering, the recess can also be used to provide sufficient foot space or legroom for a passenger seat located behind it.

[0033] In an advantageous embodiment, an outward bulge is arranged on the second utility wall, from which the toilet unit faces away. If the second utility wall in question has a washbasin, the bulge can be arranged in an area lying between the washbasin and the toilet unit. The bulge is located at least at a height above the toilet unit and extends essentially to a top side of the toilet module. However, it can also extend to a lower area. This provides space for the user's shoulder without having to change the basic dimensions of the toilet module.

[0034] In an advantageous embodiment, an attendant seat is arranged on the second useful wall, from which the toilet unit faces away. The attendant seat can preferably be accommodated in an area facing the front wall. The attendant seat is preferably a foldable seat that is only folded out when needed, for example during takeoff and landing in the case of an aircraft. This leaves the toilet module space for a bulge in the second useful wall, from which the toilet unit faces away. The bulge can preferably be designed such that it corresponds to the external dimensions, i.e. in particular the installation depth, of the attendant seat in a folded-in state. The attendant seat is particularly preferably arranged on a second useful wall that does not have an indentation.

[0035] The invention further relates to a vehicle having a vehicle cabin and a toilet module as described above. In a particularly advantageous embodiment, the vehicle can be an aircraft, in particular a commercial aircraft. The vehicle cabin can also be a passenger cabin. SHORT DESCRIPTION OF THE CHARACTERS

All described and / or illustrated features, individually and in any combination, constitute the subject matter of the invention, regardless of their composition in the individual claims or their references. In the figures, the same reference numerals continue to represent the same or similar objects. Fig. 1 shows a toilet module in a three-dimensional view. Fig. 2 shows a transparent toilet module from the same direction as in Fig. 1. Fig. 3 shows a top view of a toilet module. Fig. 4 shows a toilet module in a side section. Fig. 5 shows a modified toilet module in a top view. Fig. 6 shows the toilet module from Fig. 5 in a three-dimensional view. Fig. 7 shows a toilet module with a recess and a bulge on two opposite second usable walls. Fig. 8 shows two staggered toilet modules. DETAILED REPRESENTATION OF EXEMPLARY EMBODIMENTS

[0037] Fig. Figure 1 shows the toilet module 1 according to the invention in a three-dimensional view from the outside. The toilet module 1 comprises a housing 2 with a front wall 4, which has an access opening 6 closed by a door 8. The access opening 6 occupies only a portion of the width of the front wall 4 and is not arranged symmetrically on the front wall 4, but is offset slightly to the left. This creates a corner area 10 that can be utilized on the inside of the toilet module 1.

[0038] To the left of the front wall 4 there is a second utility wall 12 which has a bulge 14 on its underside which enlarges the usable space inside the toilet module 1, but due to a necessary bevel 16 on the outside of the toilet module 1 it allows in particular the swiveling in of backrests of passenger seats which are arranged directly adjacent to the toilet module 1.

[0039] On an upper side 18 of the toilet module 1, the second utility wall 12 has a cutout 20 that is accessible from the inside. Typically, when the toilet module 1 is arranged next to a corridor in a vehicle cabin, overhead storage compartments are located to the left and right of the toilet module 1, which in turn are preferably attached to the fuselage frames. The fuselage frames have a certain, predetermined distance from one another and thus limit the installation positions of overhead storage compartments. The distance between the second utility wall 12 and the last fuselage frame that can be used for attaching an overhead storage compartment can be filled with an additional storage compartment 21 that extends outwards from the cutout 20 of the second utility wall 12 and into Fig. 1 is shown in dashed lines. This allows consumables such as towels and the like to be stored without wasting valuable space within the toilet module 1.

[0040] Fig. Figure 2 shows, in a transparent representation, the arrangement of fixtures within the toilet module 1. Here, a further second utility wall 24 is visible, which supports a washbasin 26 that extends from this second utility wall 24 into the area 10 of the front wall 4. The washbasin 26 is therefore located as far as possible in the corner between the front wall 4 and the second utility wall 24, which form a right angle to each other.

[0041] A toilet unit 30 is arranged on a first utility wall 28, opposite the front wall 4, and extends from the first utility wall 28 into the interior of the toilet module 1. The toilet unit 30 is arranged at the greatest possible distance from the washbasin 26. The toilet unit 30 is located approximately centrally on the first utility wall 28 and is pivoted slightly to the left. A longitudinal axis of the toilet unit, indicated in the following illustration, therefore forms an angle other than zero with the second utility wall 24, which supports the washbasin 26.

[0042] Fig. Figure 3 shows the structure in a plan view of the toilet module 1 in a somewhat clearer manner. The toilet unit 30 has a longitudinal axis 32 which runs obliquely to the second utility wall 24 and the second utility wall 12. An angle a between the longitudinal axis 32 and the second partition wall 24 is particularly preferably in a range of 15 to 45°. For the sake of clarity, the angle a in Fig. 3 drawn with a parallel to the second utility wall.

[0043] The toilet unit 30 is therefore facing away from the second utility wall 24 and towards the first utility wall 12.

[0044] Furthermore, the washbasin 26 extends completely over the corner area 10 of the front wall 4, still protruding slightly in front of the access opening 6. To avoid impacts and to ensure a visually appealing shape, the washbasin 26 is drop-shaped, i.e., a washbasin is embedded in a drop-shaped, curved shelf. The space between the washbasin 26 and the toilet unit 30 can therefore have a virtually constant width, creating a particularly comfortable feeling of space.

[0045] For example, the first utility wall 28 is not aligned parallel to the front wall 4, but rather runs at a certain angle to it. The toilet module 1 tapers or widens across its width, so that the toilet module 1 can be arranged in the area of ​​an aircraft's tail cone.

[0046] Fig. 4 shows a person 34 using the toilet unit 30, enjoying a fairly comfortable feeling of space despite the reduced width of the toilet module 1. The person's knees and feet can extend into an area within the bulge 14, so that the overall width of the toilet module 1 can be reduced, as long as unobstructed sitting on the toilet unit 30 is possible. The inventive design of the toilet module 1 allows a width of approximately 10 inches to be saved for the toilet module 1, which often allows for the accommodation of an additional row of passenger seats in the vehicle, for example, an aircraft. The distance between passenger seat rows is typically 28-32 inches.

[0047] In an area above the toilet unit, a vertical boundary surface 36 can extend to the first utility wall 28 and enclose a storage space 38 there. The boundary surface 36 can serve as a backrest for the person 34. This design is particularly recommended with a curved first utility wall 28, since the person 34 cannot lean against a curved first utility wall 28 anyway. To enlarge the storage space 38, the toilet unit 30 can optionally be moved further into the interior of the toilet module 1.

[0048] In Fig. 5 shows a plan view of how a toilet module 39 can additionally have a bulge 40 on the second utility wall 24, from which the toilet unit 30 faces away. This bulge provides a person inside the toilet module 39 with sufficient mobility, particularly when the bulge is arranged at a height above the toilet unit 30. At the same time, an attendant seat 42 can be arranged next to the bulge 40, in an area facing the front wall 4, which seat is particularly preferably designed as a folding seat. The depth of the bulge 40 and the attendant seat 42 correspond to one another, so that the attendant does not feel cramped when sitting.

[0049] Fig. Figure 6 shows the toilet module 39 in a three-dimensional view, clearly showing the bulge 40 and the attendant seat 42 enclosed thereby. In addition, the toilet module 39 has a side storage compartment 21 and a bulge 14 on the second utility wall 12, toward which the toilet unit 30 faces.

[0050] Fig. Figure 7 shows a toilet module 44 that has a bulge 48 on a second utility wall 46, toward which the toilet unit 30 faces. On an opposite second utility wall 52, there is a recess 50 whose shape corresponds to the shape of the bulge 48. This allows sufficient foot space to be provided for a passenger seat 54 located behind it.

[0051] Finally, Fig. 8 a staggered arrangement of a toilet module 44 from Fig. 7 in mirrored form and a toilet module 39 from Fig.6, although the latter does not have an external storage compartment 21. The second usable wall of the left toilet module 44 nestles against the second usable wall of the right toilet module 39, creating a unit consisting of two toilet modules.

[0052] Additionally, it should be noted that "comprising" does not exclude other elements or steps, and "a" or "an" does not exclude a plurality. Furthermore, it should be noted that features described with reference to one of the above embodiments can also be used in combination with other features of other embodiments described above. Reference signs in the claims are not to be considered as limitations.
