Description

Technical Field

[0001] The present invention relates to a private room structure that can be mounted on an aircraft.

Background Art

[0002] Currently, in passenger aircraft called wide-body aircraft, which have two or more aisles, it is legally obligatory to provide one or more lavatories (in-flight toilets) that can be used by passengers using wheelchairs. On the other hand, the private rooms of general lavatories for passengers are relatively small, for example, with an outer dimension of 38 inches × 41 inches (965 mm × 1041 mm) in plan view, so it is difficult for a passenger sitting in a wheelchair to enter the private room.

[0003] Therefore, in order to enable passengers using wheelchairs to easily use them, for example, a large private room with a size slightly larger than that of a general lavatory private room, for example, with an outer dimension of 56 inches × 41 inches (1422 mm × 1041 mm) in plan view, is installed, or as shown in Patent Document 1, removing the internal wall between two adjacent standard lavatory private rooms and using it as one private room has been considered.

Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, when a passenger using a wheelchair uses the private room of the lavatory, it is not limited to the case where the passenger himself / herself can move between the wheelchair and the toilet. In some cases, without the help of an assistant, the passenger cannot move between the wheelchair and the toilet. In the latter case, even if the private room of the lavatory in the passenger aircraft is a large private room that can be used by passengers using wheelchairs, there is often no space for an assistant to enter, and appropriate assistance may not be possible.

[0006] On the other hand, since there is little space in an aircraft cabin, if the lavatory compartments were to be enlarged beyond their current size, the number of seats would have to be reduced accordingly, which would result in a decrease in the number of passengers that can board.

[0007] The present invention has been made in consideration of such problems, and aims to provide a compartment structure that can be installed on an aircraft and that can increase the occupied space of the lavatory while suppressing a reduction in the number of seats.

Embodiments for Carrying Out the Invention

[0015] Hereinafter, with reference to the drawings, an individual room structure mountable on an aircraft according to an embodiment of the present invention will be described. FIG. 1 is a plan view showing an enlarged view near the lavatory of the aircraft 1. The traveling direction of the aircraft is indicated by an arrow F in FIG. 1, and the width direction is indicated by an arrow W.

[0016] In the passenger cabin of the aircraft 1, here, three seat units 2 arranged side by side in the width direction W are arranged in three rows in the width direction W, and there is a longitudinal passage 3 between the seat units 2.

[0017] Fuselage doors 4 are arranged on both sides of the aircraft 1. In the region sandwiched between the two fuselage doors 4, the interval between the seat units 2 in the traveling direction F is relatively wide, forming a passage connecting the fuselage doors 4 on both sides. This passage is called a cross aisle. In the present embodiment, a private room structure 10 is arranged in the cross aisle. In this specification, when referring to "small", "medium", and "large", the medium space volume is larger than the small space volume, and the large space volume is larger than the medium space volume.

[0018] (First Embodiment) Figs. 2A to 2C are plan views showing the private room structure 10 of the first embodiment in an enlarged manner. The private room structure 10 includes two lavatory compartments 11 and 12 arranged along the width direction W, a partition 13 arranged behind the lavatory compartments 11 and 12 in the traveling direction, and a shared passage 15 formed between the lavatory compartments 11 and 12 and the partition 13. Let the distance between the lavatory compartments 11 and 12 and the partition 13 (that is, the passage width of the shared passage 15) be L1. Including the embodiments described later, the lavatory compartments 11 and 12 may be arranged behind the aircraft 1 in the traveling direction, and the partition 13 may be arranged in front of the traveling direction.

[0019] In the lavatory compartment (also referred to as a secondary lavatory compartment) 11, a toilet 11b is provided so as to be in contact with the front wall 11a in the traveling direction front, and a washbasin 11d is provided on the side wall (also referred to as the first side wall) 11c opposite to the lavatory compartment 12. The washbasin 11d extends from the front wall 11a to the rear wall (also referred to as the first rear wall) 11e in the traveling direction rear. The rear wall 11e extends from the side wall 11c parallel to the front wall 11a by a predetermined distance and can be connected to the opening / closing door 11f. The upper and lower ends of the front wall 11a, the side wall 11c, and the rear wall 11e are fixed to the fuselage of the aircraft 1.

[0020] The laboratory compartment (also referred to as the main laboratory compartment) 12 is provided with a toilet 12b so as to be in contact with the front wall 12a in the forward direction of travel aligned with the front wall 11a, and a washbasin 12d is provided on a side wall (also referred to as the second side wall) 12c parallel to the side wall 11c on the side opposite to the laboratory compartment 11. The washbasin 12d extends from the front wall 12a to the rear wall (also referred to as the second rear wall) 12e in the rearward direction of travel. The rear wall 12e extends from the side wall 12c in a direction parallel to the front wall 12a and opposite to the rear wall 12e by a predetermined distance and can be connected to the opening and closing door 12f. The upper and lower ends of the front wall 12a, the side wall 12c, and the rear wall 12e are fixed to the fuselage of the aircraft 1.

[0021] The laboratory compartments 11 and 12 may be symmetrically shaped with an intermediate wall (also referred to as a variable wall) 14 shown in FIG. 2A interposed therebetween, and the toilet and the washbasin are arranged symmetrically with the intermediate wall 14 interposed therebetween. The intermediate wall 14 partitions the space between the laboratory compartments 11 and 12. The front walls 11a and 12a constituting the front walls of the laboratory compartments 11 and 12 may be a single wall. Also, the rear walls 11e and 12e constitute the rear wall. Further, the front walls 11a and 12a, the side walls 11c and 12c, and the rear walls 11e and 12e constitute an outer shell. However, there is also an outer shell that does not include the rear wall 11e.

[0022] The intermediate wall 14 has a fixed wall 14a extending parallel to the side walls 11c and 12c and fixedly connected to the front walls 11a and 12a, a movable wall 14b pivotable with respect to the edge of the fixed wall 14a, and a plate-shaped support portion 14c having a central portion connected to the edge of the movable wall 14b. The support portion 14c is in the same plane as the rear walls 11e and 12e. An opening and closing door 11f is pivotably connected to the edge of the support portion 14c on the rear wall 11e side via a door hinge 11h having a rotation axis perpendicular to the floor, and an opening and closing door 12f is pivotably connected to the edge of the support portion 14c on the rear wall 12e side via a door hinge 12h having a rotation axis perpendicular to the floor. At least one of the opening and closing doors 11f and 12f constitutes a wall-integrated door.

[0023] 3A to 3C are perspective views of the intermediate wall 14, but for ease of understanding, they show only the opening / closing door 11f attached. If the width of the opening / closing door 11f is L2, then L2 = L1. The opening / closing door 11f has a door lock 11g. The door lock 11g is a common type in which a key is extended or extended or a key is engaged or disengaged by operating a lever, for example, and therefore a description thereof will be omitted. Similar door locks are also provided on the opening / closing door 12f and the passage doors 13d and 13e, which will be described later.

[0024] The fixed wall 14a and the movable wall 14b are connected by a hinge 14d having a rotation axis perpendicular to the floor, and the movable wall 14b is rotatable relative to the fixed wall 14a by the hinge 14d. The movable wall 14b has a locking mechanism 16 disposed at one location each on the upper and lower ends near the opening and closing door 11f, or at two locations each. However, when the locking mechanism 16 is disposed at two locations on the upper and lower ends, it is preferable to dispose it near both widthwise edges, and when the locking mechanism 16 is disposed at one location on the upper and lower ends, it is preferable to dispose it near the edge away from the hinge 14d.

[0025] 4A to 4C are perspective views showing an example of the locking mechanism 16. The locking mechanism 16 has a pin 16a that is disposed in the inner space of the movable wall 14b and is movable between an upper position and a lower position, and a lever 16b. In addition, a hole (not shown) into which the pin 16a can fit is formed in the ceiling and floor (included in the lavatory or aircraft body, the same applies below) facing the pin 16a.

[0026] The end of lever 16b is connected to pin 16a, and pin 16a rises when lever 16b is moved upward from the lower position shown in FIG. 4A to the position shown in FIG. 4B. When pin 16a rises to the upper position shown in FIG. 4C, it engages with a hole (not shown) and enters a locked state. When pin 16a moves to the upper position, lever 16b is tilted to the accommodated position of movable wall 14b, thereby fixing the position of protruding pin 16a and maintaining the locked state in which pin 16a engages with the hole. The locking mechanism 16 is not limited to the above configuration.

[0027] In Figures 3A to 3C, in a locked state where pins 16a of locking mechanisms 16 arranged at the upper and lower ends of movable wall 14b are engaged with holes not shown, movable wall 14b does not rotate relative to fixed wall 14a, and only opening / closing door 11f (or opening / closing door 12f) rotates relative to movable wall 14b.

[0028] As shown in Figure 2A, the partition 13 has a fixed partition wall 13a attached to the floor and ceiling and extending vertically, and passage doors 13d and 13e connected to both ends of the fixed partition wall 13a via hinges 13b and 13c. The passage doors 13d and 13e are rotatable relative to the fixed partition wall 13a by the hinges 13b and 13c, which have rotation axes perpendicular to the floor. The width of the passage doors 13d and 13e is L3, where L3 = L1. Note that the passage doors 13d and 13e may be opened and closed by sliding relative to the side walls 11c and 12c or the fixed partition wall 13a.

[0029] (1st form) 2A shows a first configuration of the compartment structure 10 of this embodiment. In the first configuration, the movable wall 14b is fixed by the locking mechanism 16. The aisle doors 13d and 13e are rotated so as to be in close contact with the fixed partition wall 13a, and are fixed in this state with, for example, fasteners or straps (not shown). In this state, the shared aisle 15 can be used as a passageway for passengers and crew members.

[0030] In addition, the intermediate wall 14 is fixed and functions as a fixed wall. The opening and closing doors 11f, 12f are each rotatable relative to the support portion 14c. Therefore, by connecting the opening and closing doors 11f, 12f to the rear walls 11e, 12e and locking the doors from the inside, small lavatory compartments 11 and 12 are formed, each surrounded by the front walls 11a, 12a, side walls 11c, 12c, rear walls 11e, 12e, the intermediate wall 14, and the opening and closing doors 11f, 12f, and these compartments can be used independently. In addition, by opening the opening and closing doors 11f, 12f, passengers can enter and exit the lavatory compartments 11 and 12 from the shared passageway 15.

[0031] (2nd form) 2B shows a second configuration of the compartment structure 10 of this embodiment. In the second configuration, as in the first configuration, the movable wall 14b connected to the support portion 14c is fixed to the ceiling and floor by the locking mechanism 16, but the opening and closing doors 11f, 12f are rotated toward the fixed partition wall 13a and fixed to the fixed partition wall 13a by the door lock 11g or the like, thereby separating the shared passageway 15. Because the width L2 of the opening and closing doors 11f, 12f is equal to the width L1 of the shared passageway 15, there is almost no gap between the locked opening and closing doors 11f, 12f and the fixed partition wall 13a, and the lavatory compartments 11 and 12 can be extended and used up to the shared passageway 15 side. That is, a medium-sized lavatory compartment 11 and a lavatory compartment 12 are formed, each surrounded by front walls 11a, 12a, side walls 11c, 12c, an intermediate wall 14, opening and closing doors 11f, 12f, and a partition 13.

[0032] At this time, by rotating aisle doors 13d, 13e on hinges 13b, 13c relative to both end edges of fixed partition wall 13a and connecting them to side walls 11c, 12c and locking the doors from the inside, expanded lavatory compartments 11, 12 can be used as separate, closed spaces without compromising privacy. Also, by opening aisle doors 13d, 13e, passengers can enter and exit expanded lavatory compartments 11, 12. Wheelchair-using passengers can enter lavatory compartments 11, 12, which have been expanded to shared aisle 15, and can use the lavatory by moving from their wheelchair to the toilet on their own.

[0033] (3rd form) Figure 2C shows the third form of the private room structure 10 of the present embodiment. In the third form, opening / closing doors 11f and 12f are brought into close contact with both sides of the fixed wall 14a and fixed with fixtures or straps or the like, and the locking mechanism 16 is released to rotate the movable wall 14b toward the lavatory private room 11 side. In order to prevent the movable wall 14b (opening / closing door 11f) from colliding with the toilet 11b, for example, a rotation restriction may be provided on the ceiling to limit further rotation by contacting the movable wall 14b (opening / closing door 11f) (the same applies to the following embodiments).

[0034] Due to the rotation of the movable wall 14b, it becomes impossible to use the lavatory private room 11. However, when the movable wall 14b rotates to the side away from the side wall 12c, the space of the lavatory private room 12 is expanded to a part of the lavatory private room 11 and the entire shared passage 15, resulting in a large-sized lavatory. That is, a large-sized lavatory private room 12 surrounded by the front wall 12a, the intermediate wall 14, the rear wall 11e, the side wall 12c, and the partition 13 is formed. Furthermore, by connecting the passage doors 13d and 13e to the side walls 11c and 12c and locking the doors from the inside, a wide closed space that does not compromise privacy is ensured. For this reason, when a wheelchair passenger who requires assistance when using the lavatory enters the lavatory private room 12, the caregiver can also enter the lavatory private room 12 to provide assistance. At this time, for example, when the wheelchair passenger enters from the passage door 13e, the caregiver enters from the opposite passage door 13d, so that their movement lines do not overlap, and efficient use of the lavatory is realized.

[0035] According to the present embodiment, it is possible to form a large space using two adjacent lavatory private rooms 11 and 12 and the shared passage 15 adjacent to the lavatory private rooms. That is, by using the opening / closing doors 11f and 12f of the lavatory private rooms 11 and 12 and the partition 13, and providing the passage doors 13d and 13e that block the shared passage 15, a large space with ensured privacy can be formed. The size of this space is, for example, 76 inches × 64 inches (1930 mm × 1625 mm) in external dimensions in plan view.

[0036] (Second Embodiment) 5A to 5C are enlarged plan views of a compartment structure 10A of a second embodiment. In this embodiment, unlike the first embodiment, the opening and closing doors 11Af, 12Af of the lavatory compartments 11, 12 are bifold (folding) type. Other configurations are the same as those of the first embodiment, so duplicated explanations will be omitted. The omission of explanations of common configurations will be the same in the following embodiments.

[0037] The door 11Af includes a first plate 11A1 having a vertically elongated rectangular shape, a second plate 11A2 having a shape substantially identical to that of the first plate 11A1, and a secondary door hinge 11A3 connecting the first plate 11A1 and the second plate 11A2. The first plate 11A1 is pivotally connected to a support portion 14c by a door hinge 11h. A door lock (not shown) is provided on the second plate 11A2. When the first plate 11A1 and the second plate 11A2 are aligned, the width of the door 11Af is L2, and L2 = L1.

[0038] Similarly, the door 12Af includes a first plate 12A1 that is vertically elongated, a second plate 12A2 that has a shape substantially identical to that of the first plate 12A1, and a secondary door hinge 12A3 that connects the first plate 12A1 and the second plate 12A2. The first plate 12A1 is pivotally connected to the support portion 14c by a door hinge 12h. A door lock (not shown) is provided on the second plate 12A2. When the first plate 12A1 and the second plate 12A2 are aligned, the width of the door 12Af is L2, and L2 = L1.

[0039] (1st form) In the first form of the private room structure 10A of this embodiment, by connecting the opening / closing doors 11Af and 12Af to the rear walls 11e and 12e and locking the doors from the inside, the small laboratory private rooms 11 and the laboratory private room 12 surrounded by walls on all sides can be used independently. Also, as shown in Fig. 5A, by unlocking the door lock and folding the first plate 11A1 and the second plate 11A2, the opening / closing door 11Af is opened, or by folding the first plate 12A1 and the second plate 12A2, the opening / closing door 12Af is opened, so that passengers can enter and exit the laboratory private room 11 or the laboratory private room 12 from the shared passage 15.

[0040] (Second form) In the second form of the private room structure 10A of this embodiment, as shown in Fig. 5B, the opening / closing doors 11Af and 12Af can be rotated to the side of the fixed partition wall 13a and fixed to the fixed partition wall 13a using a door lock. Since the lateral width L2 of the opening / closing doors 11Af and 12Af is equal to the width L1 of the shared passage 15, there is almost no gap between the locked opening / closing doors 11Af and 12Af and the fixed partition wall 13a, and the laboratory private room 11 and the laboratory private room 12 can be extended to the side of the shared passage 15 and used as medium-sized laboratory private rooms. The laboratory private room 11 and the laboratory private room 12 are sealed or opened by the passage doors 13d and 13e.

[0041] (Third form) In the third form of the private room structure 10A of this embodiment, as shown in Fig. 5C, the opening / closing doors 11Af and 12Af are closely attached to both sides of the fixed wall 14a and fixed with fixtures or straps, etc., and the locking mechanism 16 is released to rotate the movable wall 14b to the side of the laboratory private room 11. Thereby, the space of the laboratory private room 12 can be further expanded to form a large-sized laboratory.

[0042] In addition, in the third form of the private room structure 10A of the present embodiment (or the first embodiment), as shown in FIG. 5D, a folding simple bed 13g can be installed upright on the passage door 13e. For example, when there is a passenger in poor condition, the simple bed 13g can be deployed on the shared passage 15 and placed horizontally, and the passenger can be laid on the simple bed 13g. Thereby, the expanded lavatory private room 12 can be used as an ambulance room.

[0043] (Third Embodiment) Figs. 6A to 6C are plan views showing an enlarged view of the private room structure 10B of the third embodiment. In the present embodiment, compared with the first embodiment, the lavatory private room 12, the intermediate wall 14, the shared passage 15, and the screen 13 are common, but the difference is that a powder room 11B is installed adjacent to the lavatory private room 12. Note that the intermediate wall 14 does not have the support portion 14c, and the opening / closing door 12f is connected to the movable wall 14b via the door hinge 12h, but the support portion 14c may be provided and the opening / closing door 12f may be connected in the same manner as in the first embodiment.

[0044] The powder room 11B is surrounded by the front wall 11a, the side wall 11c, and the intermediate wall 14, but there is no rear wall and no opening / closing door, and it is connected to the shared passage 15. A washstand 11d and a mirror are installed on the front wall 11a. The width (length in the traveling direction) of the washstand 11d is preferably smaller than the width of the fixed wall 14a. Note that instead of the powder room 11B, a nursing room, a fitting room, a warm-up / cool-down space, an ambulance room, etc. (that is, a non-lavatory private room) can be provided.

[0045] (First Form) In the first form of the private room structure 10B of the present embodiment, by connecting the opening / closing door 12f to the rear wall 12e and locking the door from the inside, a small lavatory private room 12 surrounded by walls can be used in the same manner as in the first embodiment. Also, as shown in FIG. 6A, by unlocking the door lock and opening the opening / closing door 12f, passengers can enter and exit the lavatory private room 12 from the shared passage 15. Since there is no opening / closing door in the powder room 11B, passengers can freely enter and exit the powder room 11B through the shared passage 15. However, by rotating the passage doors 13d and 13e with respect to the fixed partition wall 13a, connecting them to the side walls 11c and 12c, and locking (shielding) them, the privacy of the powder room 11B can be ensured.

[0046] (Second form) In the second form of the private room structure 10B of the present embodiment, as shown in FIG. 6B, the opening / closing door 12f can be rotated toward the fixed partition wall 13a side and fixed to the fixed partition wall 13a using a door lock. Since the lateral width L2 of the opening / closing door 12f is equal to the width L1 of the shared passage 15, there is no gap between the locked opening / closing door 12f and the fixed partition wall 13a. Thus, without compromising privacy, the lavatory private room 12 can be extended up to the shared passage 15 side and used as a medium-sized lavatory private room in the same manner as in the first embodiment. The lavatory private room 12 is sealed or opened by the passage door 13e.

[0047] At this time, the passage door 13d can be rotated with respect to the fixed partition wall 13a, connected to the side wall 11c, and locked from the inside. Since the shared passage 15 is shielded by the opening / closing door 12f, the privacy of the powder room 11B can be ensured by locking the passage door 13d.

[0048] (Third form) In the third form of the cubicle structure 10B of this embodiment, as shown in Fig. 6C, the opening and closing door 12f is attached to one side of the fixed wall 14a and secured with a fixture or strap, and the locking mechanism 16 is released to rotate the movable wall 14b toward the powder room 11B. Because the powder room 11B does not have a toilet, the movable wall 14b can be rotated until it is aligned with the sink 11d. Therefore, the rotation angle of the movable wall 14b is larger than in the first embodiment, and the space of the lavatory cubicle 12 can be further expanded to form a large lavatory cubicle.

[0049] (Fourth embodiment) 7A to 7C are enlarged plan views of a compartment structure 10C according to a fourth embodiment. This embodiment differs from the second embodiment in that a bifold-type opening and closing door 12Cf is provided in the lavatory compartment 12. The opening and closing door 12Cf has a structure similar to that of the opening and closing door 12Af. The powder room 11B is the same as that of the third embodiment.

[0050] (1st form) In the first form of the compartment structure 10C of this embodiment, the small lavatory compartment 12 surrounded by walls can be used as in the second embodiment by connecting the opening / closing door 12Cf to the rear wall 12e and locking the door from the inside. As shown in FIG. 7A, by unlocking the door and opening the opening / closing door 12Cf, passengers can enter and exit the lavatory compartment 12 via the shared passageway 15. Because the powder room 11B does not have a door, passengers can freely enter and exit the powder room 11B via the shared passageway 15. However, privacy of the powder room 11B can be ensured by rotating the passageway doors 13d and 13e relative to the fixed partition wall 13a and connecting and locking (shielding) them to the side walls 11c and 12c.

[0051] (2nd form) In the second form of the private room structure 10C of the present embodiment, as shown in FIG. 6B, the opening / closing door 12Cf can be rotated toward the fixed partition wall 13a and fixed to the fixed partition wall 13a using the locking mechanism 16. Since the lateral width L2 (see FIG. 5B) of the opening / closing door 12Cf in the extended state is equal to the width L1 of the combined passage 15, there is almost no gap between the locked opening / closing door 12Cf and the fixed partition wall 13a, and the laboratory private room 12 can be extended to the combined passage 15 side and used as a medium-sized laboratory private room as in the second embodiment. The laboratory private room 12 is sealed or opened by the passage door 13e.

[0052] At this time, the passage door 13d can be rotated with respect to the fixed partition wall 13a, connected to the side wall 11c, and locked from the inside. Since the combined passage 15 is shielded by the opening / closing door 12Cf, the privacy of the powder room 11B can be ensured by locking the passage door 13d.

[0053] (Third form) In the third form of the private room structure 10C of the present embodiment, as shown in FIG. 7C, the opening / closing door 12Cf is brought into close contact with one side of the fixed wall 14a and fixed with a fixing tool, a strap, or the like, and the locking mechanism 16 is released to rotate the movable wall 14b toward the powder room 11B side. Since there is no toilet in the powder room 11B, the movable wall 14b can be rotated along the washstand 11d. Therefore, the rotation angle of the movable wall 14b is larger than that in the first embodiment, and the space of the laboratory private room 12 can be further expanded to form a large-sized laboratory private room.

[0054] (Fifth embodiment) FIGS. 8A to 8B are enlarged plan views showing the private room structure 10D of the fifth embodiment. In the present embodiment, different from the third embodiment, instead of connecting an opening / closing door to the movable wall 14b, an opening / closing door 12Df, which is a sliding door, is provided on the rear wall 12e side.

[0055] (First form) Also in the first form of the private room structure 10D of the present embodiment, by sliding the opening / closing door 12Df toward the intermediate wall 14 to shield the space between the fixed movable wall 14b and the rear wall 11e and connecting it to the movable wall 14b and locking it from the inside, a small-sized lavatory private room 12 surrounded by walls can be used in the same manner as in the third embodiment. Further, as shown in Fig. 8A, by unlocking the door lock and sliding the opening / closing door 12Df toward the rear wall 12e to open it, passengers can enter and exit the lavatory private room 12 from the shared passage 15. Since there is no opening / closing door in the powder room 11B, passengers can freely enter and exit the powder room 11B through the shared passage 15. However, by rotating the passage doors 13d and 13e with respect to the fixed partition wall 13a, connecting them to the side walls 11c and 12c, and locking (shielding) them, the privacy of the powder room 11B can be ensured.

[0056] (Second form) In the second form of the private room structure 10D of the present embodiment, as shown in Fig. 8B, the opening / closing door 12Df is slid and fixed toward the rear wall 11e, and further, the locking mechanism 16 is released to rotate the movable wall 14b toward the powder room 11B. Since there is no toilet in the powder room 11B, the movable wall 14b can be rotated until it reaches along the washstand 11d. Therefore, the rotation angle of the movable wall 14b is larger than that in the first embodiment, and the space of the lavatory private room 12 can be further expanded to form a large-sized lavatory private room. The large-sized lavatory private room 12 is surrounded by the front wall 12a, the fixed wall 14a, the movable wall 14b, the partition 13, and the side walls 11c and 12c, and includes the shared passage 15. By rotating the passage doors 13d and 13e with respect to the fixed partition wall 13a, connecting them to the side walls 11c and 12c, and locking (shielding) them, the privacy of the lavatory private room 12 can be ensured.

[0057] (Sixth embodiment) Figs. 9A to 9C are plan views showing an enlarged view of the private room structure 10E of the sixth embodiment. In the present embodiment, compared with the third embodiment, the arrangement of the interior fittings in the powder room 11E and the lavatory private room 12E is different, but the shared passage 15 and the partition 13 are common.

[0058] In the powder room 11E, the washstand 11d is arranged from the front wall 11a to the rear wall 11e in a state of being in close contact with the side wall 11c.

[0059] The toilet cubicle 12E has an intermediate wall 14E that is only the fixed wall 14a. The washstand 12d is arranged from the fixed wall 14a to the side wall 12c in a state of being in close contact with the front wall 12a. Adjacent to the washstand 12d, the toilet 12b is attached to the side wall 12c. The partition 13 only needs to have the passage door 13d, but may have the passage door 13e as in the above-described embodiment.

[0060] The side edge of the rear wall 12e is connected to one side edge of the movable wall 12E1 via a hinge 12E2, and the movable wall 12E1 is rotatable with respect to the rear wall 12e. Also, the opening / closing door 12Ef is rotatably connected to the other side edge of the movable wall 12E1 via a hinge 12E3. The hinges 12E2 and 12E3 have a rotation axis perpendicular to the floor. The movable wall 12E1 has a locking mechanism 16, and when the lateral width of the movable wall 12E1 is L4, substantially L4 = L1. The opening / closing door 12Ef has a door lock (not shown).

[0061] (First embodiment) In the first form of the cubicle structure 10E of the present embodiment, the movable wall 12E1 is fixed to the ceiling and the floor by a locking mechanism 16. Thereby, by connecting the opening / closing door 12Ef to the fixed wall 14a and locking the door from the inside, a small toilet cubicle 12E surrounded by the front wall 12a, the fixed wall 14a, the opening / closing door 12Ef, the side wall 12c, the rear wall 12e, and the movable wall 12E1 can be used. Also, as shown in FIG. 9A, by unlocking the door lock and opening the opening / closing door 12Ef, the passenger can enter and exit the toilet cubicle 12E through the powder room 11E. Since there is no opening / closing door in the powder room 11E, the passenger can freely enter and exit the powder room 11E through the shared passage 15.

[0062] (Second embodiment) In the second form of the private room structure 10E of this embodiment, as shown in FIG. 9B, the opening / closing door 12Ef can be rotated to the rear wall 11e of the powder room 11E, and the opening / closing door 12Ef is connected to the rear wall 11e and locked from the inside, so that the front wall 12a, the side wall 11c, the rear wall 11e, the side wall 12c, the rear wall 12e, the movable wall 12E1, and the opening / closing door 12Ef can enclose a lavatory private room 12E. Thereby, the lavatory private room 12E can be extended to the powder room 11E and used as a medium-sized lavatory private room.

[0063] (Third form) In the third form of the private room structure 10E of this embodiment, after releasing the locking mechanism 16 of the movable wall 12E1, as shown in FIG. 9C, the movable wall 12E1 is rotated 90 degrees to the side of the fixed partition wall 13a and fixed by the locking mechanism 16 and the like. Further, the opening / closing door 12Ef is fixed in a state of being in close contact with the fixed partition wall 13a by a fixture or a strap (not shown). Since the lateral width L4 of the movable wall 12E1 is substantially equal to the width L1 of the shared passage 15, there is almost no gap between the locked movable wall 12E1 and the fixed partition wall 13a. Thereby, without impairing privacy, the lavatory private room 12E can be further extended to the side of the shared passage 15 and used as a large-sized lavatory private room. At this time, the lavatory private room 12E is surrounded by the front walls 11a, 12a, the side walls 11c, 12c, the rear wall 12e, the movable wall 12E1, and the partition 13, includes a part of the shared passage 15, and is sealed or opened by the passage door 13d.

[0064] (Seventh embodiment) FIGS. 10A to 10C are enlarged plan views showing the private room structure 10F of the seventh embodiment. In this embodiment, compared with the sixth embodiment, the opening / closing door 12Ff is changed to a bifold type, and the other configurations are the same. Also, the opening / closing door 12Ff has the same structure as the opening / closing door 12Af. If the lateral width of the opening / closing door 12Ff in the extended state is L2, then L2 = L1 (see FIG. 5B). The opening / closing door 12Ff has a door lock (not shown).

[0065] (First form) In the first form of the private room structure 10F of this embodiment, the movable wall 12E1 is fixed to the ceiling and the floor by the locking mechanism 16. Thus, by connecting the opening / closing door 12Ff to the movable wall 12E1 and locking the door from the inside, a small lavatory private room 12E surrounded by walls can be used in the same manner as in the sixth embodiment. Further, as shown in FIG. 10A, by releasing the door lock and opening the opening / closing door 12Ff, passengers can enter and exit the lavatory private room 12E through the powder room 11E. Since there is no opening / closing door in the powder room 11E, passengers can freely enter and exit the powder room 11E through the shared passage 15.

[0066] (Second form) In the second form of the private room structure 10F of this embodiment, as shown in FIG. 10B, the opening / closing door 12Ff can be rotated to the rear wall 11e side of the powder room 11E, and by connecting the opening / closing door 12Ff to the rear wall 11e and locking the door from the inside, the lavatory private room 12E can be expanded up to the powder room 11E and used as a medium-sized lavatory private room.

[0067] (Third form) In the third form of the private room structure 10F of this embodiment, after releasing the locking mechanism 16 of the movable wall 12E1, as shown in FIG. 10C, the movable wall 12E1 is rotated to the fixed partition wall 13a side and can be fixed to the fixed partition wall 13a using the locking mechanism 16 or the like. Further, the opening / closing door 12Ff can be fixed in a state of being in close contact with the fixed partition wall 13a using a fixture or a strap (not shown). Since the lateral width L4 of the movable wall 12E1 is substantially equal to the width L1 of the shared passage 15, there is no gap between the locked movable wall 12E1 and the fixed partition wall 13a, and thus the lavatory private room 12E can be further expanded to the shared passage 15 side without compromising privacy and used as a large-sized lavatory private room. The lavatory private room 12E is sealed or opened by the passage door 13d.

[0068] (Eighth embodiment) Figs. 11A to 11B are plan views showing an enlarged individual room structure 10G of the eighth embodiment.

The opening / closing door 12f is rotatable with respect to the movable wall 14Gb via a door hinge 12h.

[0069] Fig. 12 is a perspective view schematically showing the movable wall 14Gb. In Fig. 12, the movable wall 14Gb has a wall portion 14G1 and a slider 14G2 attached to the center of the upper edge of the wall portion 14G1. A curtain rail 1G is attached to the ceiling of the lavatory (individual room structure) so as to extend from the lavatory individual room 12 toward the powder room 11B. The curtain rail 1G is, for example, a long member having a C-shaped cross section with an opening facing downward. The slider 14G2 has a T shape that engages with the curtain rail 1G. With the slider 14G2 attached to the curtain rail 1G, the wall portion 14G1 is supported in an upright state, and the slider 14G2 can be moved along the curtain rail 1G together with the wall portion 14G1 while maintaining the upright state. Although not shown, the wall portion 14G1 has a locking mechanism 16.

[0070] (First form) In the first form of the individual room structure 10G of this embodiment, the movable wall 14Gb is fixed to the ceiling and the floor by a locking mechanism 16, and the fixed wall 14a and the movable wall 14Gb are in a connected state. Thereby, as shown in Fig. 11A, by connecting the opening / closing door 12f to the rear wall 12e and locking the door from the inside, a small lavatory individual room 12 surrounded by walls can be used in the same manner as in the third embodiment. Since there is no opening / closing door in the powder room 11B, passengers can freely enter and exit the powder room 11B through the shared passage 15. However, by rotating the passage doors 13d and 13e with respect to the fixed partition wall 13a, connecting them to the side walls 11c and 12c, and locking (shielding) them, the privacy of the powder room 11B can be ensured.

[0073] (First form) In the first form of the private room structure 10H of the present embodiment, the movable wall 14Gb is fixed to the ceiling and the floor by the lock mechanism 16, and the fixed wall 14a and the movable wall 14Gb are in a connected state. As a result, as shown in FIG. 13A, by connecting the opening / closing door 12Hf to the rear wall 12e and locking the door from the inside, a small lavatory private room 12 surrounded by walls can be used in the same manner as in the eighth embodiment. Since there is no opening / closing door in the powder room 11B, passengers can freely enter and exit the powder room 11B through the shared passage 15. However, by rotating the passage doors 13d and 13e with respect to the fixed partition wall 13a and connecting and locking (shielding) them to the side walls 11c and 12c, the privacy of the powder room 11B can be ensured.

[0074] (Second form) In the second form of the private room structure 10H of the present embodiment, by releasing the lock mechanism 16 of the movable wall 14Gb, as shown in FIG. 13B, the movable wall 14Gb is moved along the curtain rail 1G and brought into close contact with the side wall 11c, and can be fixed to the side wall 11c together with the opening / closing door 12Hf using a fixture or strap (not shown). As a result, without impairing privacy, the lavatory private room 12 can be expanded to the powder room 11B and the shared passage 15 side and used as a large-sized lavatory private room. The privacy of the lavatory private room 12 can be ensured by rotating the passage doors 13d and 13e with respect to the fixed partition wall 13a and connecting and locking (shielding) them to the side walls 11c and 12c.

[0075] (Embodiment 10) FIGS. 14A to 14B are plan views showing an enlarged private room structure 10I of the tenth embodiment. In the present embodiment, compared with the eighth embodiment, the opening / closing door 12If is changed to a sliding type, and the other configurations are the same.
