[0003] [Patent Document 1] Special Publication No. 2006-510531 Summary of the Invention [Problem to be solved by the invention]

[0004] On a ship, if a passenger or crew member becomes infected with an infectious disease, it is desirable to isolate the infected person from other passengers and crew members who are not infected within the limited space of the ship. However, it is difficult for a ship with limited space to always have rooms for isolating infectious disease patients on board in case of an infectious disease epidemic. Furthermore, isolating and accommodating multiple infectious disease patients in a large space such as a hall or foyer is not effective in terms of preventing infection or ensuring privacy.

[0005] Therefore, it is desirable to be able to convert cabins that are normally used as living spaces for crew and passengers into isolation spaces for infectious disease patients in the event of an outbreak. In this case, it is desirable to effectively isolate cabins housing infectious disease patients from other spaces, such as corridors connected to the cabins, in order to prevent the spread of infection.

[0006] The present disclosure has been made to solve the above-mentioned problems, and aims to provide a floating body that can effectively suppress the spread of infectious diseases and make effective use of limited space on board a ship. [Means for solving the problem]

[0007] In order to solve the above problems, a float according to the present disclosure comprises a float body, a passageway, a plurality of cabins, a first door, a second door, and a pressure adjustment unit. The passageway is provided within the float body. The plurality of cabins are arranged along the passageway. Each of the plurality of cabins has a main cabin and an auxiliary cabin. The first door is provided so as to be able to separate the passageway from the main cabin. The second door is openable and closable between a first position and a second position. In the first position, the second door is 、 In the second position, the second door divides the main room and the sub-room. The main room Lobby space and the above Excluding the lobby space Divide the space into living spaces. When the second door is in the second position, it does not separate the main room from the antechamber, and forms the lobby space between the first door and the second door. The pressure adjusting unit is capable of adjusting the pressure in the passageway, the lobby space, and the living space so that the pressure in the living space is lower than the pressure in the lobby space and the passageway. [Effects of the Invention]

[0008] The float of the present disclosure can effectively prevent the spread of infectious diseases and make effective use of limited space on board the ship. [Brief explanation of the drawings]

[0010] Hereinafter, a floating body according to an embodiment of the present disclosure will be described with reference to FIGS. (Vessel configuration) As shown in Fig. 1, a ship (floating body) 1 as a floating body in this embodiment includes at least a hull (floating body main body) 2 as a floating body main body, a plurality of cabins 10, and a pressure adjustment unit 80 (see Fig. 3). In this embodiment, the ship 1, such as a ferry or passenger ship that can navigate by a main engine or the like, will be described as an example of a floating body.

[0011] The hull 2 has a pair of side walls 3A, 3B, a bottom 4, and an upper deck 5 that form its outer hull. The side walls 3A, 3B are equipped with a pair of side wall shell plates that form the port and starboard sides, respectively. The bottom 4 is equipped with a bottom wall shell plate that connects the side walls 3A, 3B. The pair of side walls 3A, 3B and the bottom 4 give the hull 2 an outer hull U-shape in a cross section perpendicular to the bow-stern direction FA. The upper deck 5 is a full-length deck that is exposed to the outside. The hull 2 has a superstructure 7 formed on the upper deck 5, which has accommodation areas. A plurality of cabins 10 are provided within the hull 2. Note that a plurality of cabins 10 may also be provided on the superstructure 7.

[0012] (Cabin configuration) As shown in Figures 2 to 4, a passage 9 is provided inside the hull 2. A plurality of cabins 10 are arranged along the passage 9. The plurality of cabins 10 are arranged in a passage longitudinal direction De, which is the direction in which the passage 9 extends. In this embodiment, the passage 9 is formed in a straight line extending in the passage longitudinal direction De. In Figures 2 to 4, a plurality of cabins 10 are provided on only one side of the passage 9, but a plurality of cabins 10 may be provided on each side of the passage 9.

[0013] The multiple cabins 10 are configured as pairs of two cabins 10 (a first cabin 10A and a second cabin 10B) adjacent to each other in the aisle longitudinal direction De. In a depth direction Dd that intersects with the aisle longitudinal direction De of the aisle 9 in the horizontal plane, the first cabin 10A and the second cabin 10B are each formed between an aisle side wall 11 on the aisle 9 side and an opposite wall 12 on the opposite side from the aisle 9 side. The aisle side wall 11 and the opposite wall 12 each rise upward from the floor surface 16 in the vertical direction Dv.

[0014] 2, the aisle side wall 11 and the opposite wall 12 each extend in the aisle longitudinal direction De of the aisle 9 when viewed from above. When the first cabin 10A and the second cabin 10B face the ship's sides 3A and 3B, the opposite wall 12 may be formed by the ship's side shell plating that forms the ship's sides 3A and 3B. In this case, the opposite wall 12 may be provided with a fixed window (not shown).

[0015] Partition walls 13 are provided on both sides of the adjacent first and second cabins 10A and 10B in the aisle longitudinal direction De—in other words, on the side of the first cabin 10A opposite the second cabin 10B in the aisle longitudinal direction De, and on the side of the second cabin 10B opposite the first cabin 10A in the aisle longitudinal direction De. An intermediate partition wall 14 is provided between the first and second cabins 10A and 10B, which are adjacent in the aisle longitudinal direction De. The partition walls 13 and 14 each rise upward in the vertical direction Dv from the floor surface 16. Furthermore, the partition walls 13 and 14 each extend in the depth direction Dd. The partition walls 13 and 14 each block the space between the aisle-side wall 11 and the opposite-side wall 12. That is, when viewed from above, the first cabin 10A and the second cabin 10B are each formed by being surrounded by an aisle side wall 11, an opposite side wall 12, a partition wall 13, and an intermediate partition wall 14.

[0016] When viewed from above, the first cabin 10A and the second cabin 10B are laid out generally symmetrically across the intermediate partition wall 14. Therefore, in the following description, the first cabin 10A and the second cabin 10B will be simply referred to as cabins 10, except when it is necessary to distinguish between them. The cabin 10 includes a main compartment 21 and an auxiliary compartment 22. The main compartment 21 is connected to the aisle 9 via an opening 11a formed in the aisle side wall 11. In other words, the main compartment 21 and the aisle 9 are in communication with each other via the opening 11a, allowing people to enter and exit the compartment.

[0017] The auxiliary chamber 22 is formed along the intermediate partition wall 14. When viewed from above, the auxiliary chamber 22 is formed in a rectangular shape extending in the depth direction Dd. When viewed from above, the auxiliary chamber 22 is partitioned by the intermediate partition wall 14, a partition wall 22a, an end wall 22b, and the passage side wall 11. The partition wall 22a is disposed at a distance from the intermediate partition wall 14 in the passage longitudinal direction De. The end wall 22b is formed in the middle of the intermediate partition wall 14 in the depth direction Dd. This end wall 22b extends in the passage longitudinal direction De and closes the gap between the intermediate partition wall 14 and the partition wall 22a. The passage 9 side of the intermediate partition wall 14 and the partition wall 22a in the depth direction Dd is closed by the passage side wall 11.

[0018] The auxiliary room 22 is connected to the main room 21 via a partition wall opening 22h formed in the partition wall 22a. In this embodiment, a toilet 101 and a shower cubicle 102 are formed within the auxiliary room 22. The toilet 101 and the shower cubicle 102 are located on either side of the partition wall opening 22h in the depth direction Dd. Specifically, the toilet 101 in this embodiment is located on the passageway 9 side in the depth direction Dd with respect to the partition wall opening 22h, and the shower cubicle 102 in this embodiment is located on the opposite side of the toilet 101 in the depth direction Dd with respect to the partition wall opening 22h.

[0019] Because the auxiliary chamber 22 is formed in this manner, the main chamber 21 is generally L-shaped when viewed from above. More specifically, the main chamber 21 has a first portion 21a and a second portion 21b. The first portion 21a extends in the depth direction Dd along the auxiliary chamber 22 from the opening 11a on the passage 9 side. The second portion 21b is located closer to the opposite wall 12 in the depth direction Dd than the auxiliary chamber 22, and is larger toward the intermediate partition wall 14 than the first portion 21a in the passage longitudinal direction De.

[0020] (Configuration of equipment and fixtures) In the main cabin 21 illustrated in this embodiment, a sink 103, a desk and chair 104, a closet 105, and a bed 107 are arranged as fixtures within the cabin 10. The sink 103 is arranged along the partition wall 13 in the first portion 21a. The desk and chair 104 is arranged in a corner of the main room 21 formed by the opposite wall 12 and the partition wall 13. The desk and chair 104 is arranged in the second portion 21b of the main room 21 on the side of the partition wall 13, away from the intermediate partition wall 14 in the longitudinal direction De of the corridor. The closet 105 is arranged on the opposite wall 12 side in the depth direction Dd with respect to the end wall 22b of the auxiliary room 22. The closet 105 is arranged in a corner formed by the end wall 22b and an intermediate connecting wall 14c of the intermediate partition wall 14, which extends from the auxiliary room 22 toward the opposite wall 12 in the depth direction Dd.

[0021] The bed 107 is disposed within the main room 21 along the opposite wall 12. The bed 107 has a rectangular shape when viewed from above, and is disposed so that its long side faces in the same direction as the longitudinal direction De of the passage.

[0022] As shown in FIGS. 2 to 5 , of the pair of adjacent cabins 10, i.e., the first cabin 10A and the second cabin 10B, the bed 107A of the first cabin 10A is disposed above the bed 107B of the other cabin, the second cabin 10B, in the vertical direction Dv. In other words, the bed 107A of the first cabin 10A is disposed at an upper portion within the first cabin 10A. Furthermore, the bed 107B of the other cabin, the second cabin 10B, is disposed below the bed 107B of the first cabin 10A and the second cabin 10B in the vertical direction Dv. In other words, the bed 107B of the second cabin 10B is disposed at a lower portion within the second cabin 10B. The bed 107A of the first cabin 10A and the bed 107B of the second cabin 10B illustrated in this embodiment are disposed so that their contours overlap when viewed from above.

[0023] The bed 107A of the first cabin 10A located on the upper side is placed on a support plate 15. The support plate 15 is located in the middle of the cabin 10 in the up-down direction Dv. The support plate 15 is formed along a horizontal plane perpendicular to the up-down direction Dv. Both ends of the support plate 15 in the depth direction Dd are connected to the opposite side wall 12 and the intermediate connecting wall 14c of the intermediate partition wall 14, respectively.

[0024] As shown in FIGS. 2 and 5, the bed 107A of the first cabin 10A, the bed 107B of the second cabin 10B, and the support plate 15 extend on both sides of the intermediate partition wall 14 in the longitudinal direction De of the aisle.

[0025] As shown in Figures 2 to 5, an upper surrounding wall 18 is provided above the support plate 15. The upper surrounding wall 18 extends upward in the vertical direction Dv from the support plate 15. When viewed from above (see Figure 2), the upper surrounding wall 18 is formed continuously from the intermediate connecting wall 14c and constitutes a part of the intermediate partition wall 14.

[0026] The upper surrounding wall 18 has an upper side wall 18a and an upper end wall 18b, and is L-shaped when viewed from above. The upper side wall 18a extends from the intermediate connecting wall 14c of the intermediate partition wall 14 along the edge of the support plate 15 toward the center of the second cabin 10B in the passage longitudinal direction De (in other words, toward the side of the second cabin 10B closer to the partition wall 13).

[0027] The upper end wall 18b is connected to the upper side wall 18a. Specifically, the upper end wall 18b extends from the edge of the upper side wall 18a on the center side of the second cabin 10B toward the opposite wall 12 in the depth direction Dd. The upper end wall 18b extends along the edge of the support plate 15 in the passage longitudinal direction De. The upper end wall 18b closes the gap between the upper side wall 18a and the opposite wall 12.

[0028] The upper surrounding wall 18 further closes the gap between the support plate 15 and the ceiling 17, closer to the center of the second cabin 10B than the intermediate connecting wall 14c in the longitudinal direction De of the passage. In other words, the upper surrounding wall 18 separates the space S1 above the bed 107A of the first cabin 10A, which protrudes above the support plate 15 and closer to the center of the second cabin 10B than the intermediate connecting wall 14c, from the space Sb within the second cabin 10B.

[0029] A lower surrounding wall 19 is provided below the support plate 15. The lower surrounding wall 19 extends downward in the up-down direction Dv from the support plate 15. When viewed from above, the lower surrounding wall 19 is formed continuously from the intermediate connecting wall 14c and constitutes a part of the intermediate partition wall 14.

[0030] The lower surrounding wall 19 has a lower side wall 19a and a lower end wall 19b and is L-shaped when viewed from above. The lower side wall 19a extends from the intermediate connecting wall 14c of the intermediate partition wall 14 along the edge of the support plate 15 to the edge of the center side of the first cabin 10A in the longitudinal direction De of the passage (in other words, the side of the first cabin 10A closer to the partition wall 13).

[0031] The lower end wall 19b is connected to the lower side wall 19a. Specifically, the lower end wall 19b extends from the edge of the lower side wall 19a on the center side of the first cabin 10A toward the opposite wall 12 in the depth direction Dd. The lower end wall 19b extends along the edge of the support plate 15 in the passage longitudinal direction De. The lower end wall 19b closes the gap between the lower side wall 19a and the opposite wall 12.

[0032] The lower surrounding wall 19 further closes the gap between the support plate 15 and the floor surface 16, closer to the center of the first cabin 10A than the intermediate connecting wall 14c in the longitudinal direction De of the passage. In other words, the lower surrounding wall 19 separates the space S2 between the bed 107B of the second cabin 10B and the support plate 15, which protrudes below the support plate 15 closer to the center of the first cabin 10A than the intermediate connecting wall 14c, from the space Sa within the first cabin 10A.

[0033] As shown in Figures 4 and 5, a ladder 108 is provided in the first cabin 10A. The ladder 108 is arranged along the lower sidewall 19a in the first cabin 10A. The ladder 108 is used to allow a user to ascend and descend between the floor 16 in the first cabin 10A and the bed 107A.

[0034] (Door configuration) As shown in FIGS. 2 to 4, a first door 51 and a second door 52 are provided in the cabin 10 (first cabin 10A, second cabin 10B). The first door 51 is configured to be able to open and close the opening 11a of the passage-side wall 11. As shown in Fig. 2, the first door 51 is a hinged door that is provided so as to be rotatable about a shaft 51s extending in the up-down direction Dv. In this embodiment, the shaft 51s is disposed on the partition wall 13 side, but the shaft 51s may also be disposed on the partition wall 22a side.

[0035] The first door 51 is rotatable between a closed state PA in which the opening 11a is closed, and an open state PB in which the opening 11a is open. When in the closed state PA, the first door 51 closes the opening 11a along the aisle side wall 11 when viewed from above. When in the closed state PA, the first door 51 is capable of separating the aisle 9 from the main compartment 21 of the cabin 10. The first door 51 opens toward the main compartment 21, not the aisle 9. When in the open state PB, the first door 51 extends in a direction intersecting the aisle side wall 11 and toward the inside of the main compartment 21 when viewed from above.

[0036] The second door 52 is provided in the main compartment 21 of the cabin 10. The second door 52 is configured to be able to open and close between a first position P1 and a second position P2. The second door 52 is a hinged door that is rotatable about an axis 52s that extends in the vertical direction Dv. The axis 52s is provided on the partition wall 22a. In the first position P1, the second door 52 closes the partition wall opening 22h of the partition wall 22a. In the first position P1, the second door 52 divides the interior of the cabin 10 into the main compartment 21 and the auxiliary compartment 22.

[0037] When in the second position P2, the second door 52 extends in a direction intersecting the partition wall 22a when viewed from above, and closes the space between the partition wall 22a and the intermediate partition wall 14. When in the second position P2, the second door 52 divides the interior of the cabin 10 into a lobby space 21L and a living space 21M.

[0038] The lobby space 21L is defined between the first door 51 and the second door 52 at the second position P2. The lobby space 21L is formed in the first portion 21a of the main room 21, closer to the aisle 9 than the second door 52. A foldable table 110 is provided on the wall surface of the partition wall 22a within the lobby space 21L.

[0039] Living space 21M is formed on the side (opposite wall 12 side) farther from passage 9 than second door 52 in second position P2. Partition wall opening 22h for entering and exiting sub-room 22 is located within living space 21M.

[0040] As shown in FIGS. 6 to 8, in this embodiment, the second door 52 includes a door body 55, a door frame 56, and a seal member 57. The door frame 56 is provided in the first portion 21a of the main room 21, between the partition wall 13 and the partition wall 22a. The door frame 56 has a rectangular shape when viewed from the depth direction Dd. The door frame 56 is formed along the outer periphery of the second door 52 in the second position P2. The door frame 56 has a first side frame 56a, a second side frame 56b, an upper frame 56c, and a lower frame 56d.

[0041] The first side frame 56a extends in the vertical direction Dv along the partition wall 13. The second side frame 56b extends in the vertical direction Dv along the partition wall 22a. The upper frame 56c extends in the aisle longitudinal direction De and connects the upper portions of the first side frame 56a and the second side frame 56b. The space between the upper frame 56c and the ceiling 17 is closed by an upper closing plate 56p. The lower frame 56d extends in the aisle longitudinal direction De along the floor surface 16. The lower frame 56d connects the lower ends of the first side frame 56a and the second side frame 56b.

[0042] The door main body 55 is provided rotatably about an axis 52s extending in the up-down direction Dv via a hinge 55j provided on the second side frame 56b. At the second position P2, the door main body 55 closes an opening surrounded by the first side frame 56a, the second side frame 56b, the upper frame 56c, and the lower frame 56d. The first side frame 56a, the second side frame 56b, and the upper frame 56c have abutment surfaces 56f facing away from the aisle 9 in the depth direction Dd. At the second position P2, the upper and both sides of the outer periphery of the door main body 55 abut against the abutment surfaces 56f of the first side frame 56a, the second side frame 56b, and the upper frame 56c.

[0043] The seal member 57 includes a first seal member 57A and a second seal member 57B. The first seal member 57A is provided along the abutment surfaces 56f of the first side frame 56a, the second side frame 56b, and the top frame 56c. The first seal member 57A is a packing made of, for example, a rubber-based material, and is sandwiched between the door body 55 of the second door 52 in the second position P2 and the abutment surfaces 56f of the first side frame 56a, the second side frame 56b, and the top frame 56c.

[0044] As shown in Figures 6 and 7, the second seal member 57B is attached to the lower end of the door main body 55. The second seal member 57B is plate-shaped or brush-shaped extending downward from the lower end of the door main body 55, and seals the gap between the door main body 55 and the lower frame 56d. The second seal member 57B is made of a rubber-based material or the like and is flexible. The second seal member 57B elastically deforms when it comes into contact with the lower frame 56d, allowing the door main body 55 to be opened and closed smoothly. Such seal members 57 (first seal member 57A, second seal member 57B) improve the airtightness between the door main body 55 and the door frame 56 at the second position P2.

[0045] The second door 52 is equipped with a transmission section 59. The transmission section 59 is formed by attaching a light-transmitting resin panel, glass panel, or the like to an opening 52h formed in the second door 52. With the second door 52 positioned at the second position P2, this transmission section 59 makes it possible to check the state of the interior of the living space 21M from the lobby space 21L side and vice versa.

[0046] (Configuration of pressure adjustment unit) As shown in Figures 3 and 4, pressure adjustment unit 80 is configured to be able to adjust the pressure in passageway 9, lobby space 21L, and living space 21M. Pressure adjustment unit 80 includes a first intake and exhaust duct 81, a second intake and exhaust duct 82, and a third intake and exhaust duct 83. First intake and exhaust duct 81, second intake and exhaust duct 82, and third intake and exhaust duct 83 each include an intake duct 84 and an exhaust duct 85. Air intake duct 84 supplies air from an air supply unit (not shown) into passageway 9, lobby space 21L, and living space 21M. Air exhaust duct 85 exhausts air from passageway 9, lobby space 21L, and living space 21M to an exhaust unit (not shown). In first air supply and exhaust duct 81, second air supply and exhaust duct 82, and third air supply and exhaust duct 83, air supply duct 84 and exhaust duct 85 each have a damper (not shown) that adjusts the amount of air supply and exhaust. Pressure adjustment unit 80 adjusts the opening of at least one of the dampers in air supply duct 84 and exhaust duct 85 to individually adjust the balance between the air supply pressure and the exhaust pressure in first air supply and exhaust duct 81, second air supply and exhaust duct 82, and third air supply and exhaust duct 83. In this way, pressure adjustment unit 80 individually adjusts the pressure in passage 9, lobby space 21L, and living space 21M.

[0047] (Example of ship operation) In the boat 1 configured as described above, for example, the cabin 10 is normally used as a living space for the crew of the boat 1. In this case, the second door 52 opens and closes as appropriate based on a first position P1 that separates the main room 21 and the auxiliary room 22.

[0048] During normal times when no infectious disease patients are accommodated in the cabin 10, the pressure adjustment unit 80 maintains the pressure in the aisle 9, lobby space 21L, and living space 21M at an equal level without specifically controlling the pressure in each of the aisle 9, lobby space 21L, and living space 21M individually.

[0049] In the event that an infectious disease patient occurs on board the ship 1, the crew will move from the cabin 10 to another cabin, etc., and the infectious disease patient will be accommodated in the cabin 10. In this case, the second door 52 is set to the second position P2, separating the lobby space 21L from the living space 21M. The infectious disease patient will only use the living space 21M of the main cabin 21 and the auxiliary cabin 22. The second door 52 is fixed in the second position P2 except when the infectious disease patient is entering or exiting the lobby space 21L from the living space 21M.

[0050] In this state, the first door 51, the second door 52, and the lobby space 21L are formed between the passage 9 and the living space 21M. This increases the isolation between the passage 9 and the living space 21M. In addition, the lobby space 21L is formed between the first door 51 and the second door 52. Various items such as food, drinks, and medicine are handed over to an infected patient in the living space 21M through the lobby space 21L. Crew members, medical staff, and other personnel who have delivered the food and other items through the aisle 9 open the first door 51 and enter the lobby space 21L. At this time, the second door 52 is in the second position P2, thereby reducing contact between the staff and the infectious disease patient in the living space 21M. The staff place the items they have brought in the lobby space 21L. By unfolding the table 110 in the lobby space 21L, the items can be placed on the table 110. At this time, the staff can visually check the condition of the infectious disease patient through the transparent portion 59. The staff then opens the first door 51 and exits the lobby space 21L to the aisle 9. The infectious disease patient in the living space 21M opens the second door 52 from the second position P2 to receive the items in the lobby space 21L. At this time, the first door 51 is closed, thereby reducing contact between the infectious disease patient and staff and other personnel passing through the aisle 9.

[0051] When an infectious disease patient is accommodated in the cabin 10, the pressure adjustment unit 80 adjusts the pressure in the aisle 9, the lobby space 21L, and the living space 21M so that the pressure in the living space 21M is lower than the pressure in the lobby space 21L and the aisle 9. This prevents the atmosphere in the living space 21M from leaking out to the lobby space 21L side.

[0052] (Action and effect) In the floating body 1 of the above embodiment, a second door 52 is provided in each cabin 10. The second door 52 can be opened and closed between a first position P1 and a second position P2. When the second door 52 is positioned at the second position P2, the second door 52 can divide the cabin 10 into a lobby space 21L on the aisle 9 side and a living space 21M away from the aisle 9. This allows the first door 51, the second door 52, and the lobby space 21L to be present between the aisle 9 and the living space 21M, enhancing the isolation between the aisle 9 and the living space 21M. Furthermore, the lobby space 21L is formed between the first door 51 and the second door 52, allowing various items such as meals to be handed over to an infected patient in the living space 21M via the lobby space 21L. Positioning the second door 52 at the second position P2 can reduce contact between staff entering the lobby space 21L and an infectious disease patient in the living space 21M. After the staff leaves the lobby space 21L to the passageway 9, the infectious disease patient in the room space 21M can open the second door 52 from the second position P2 to receive the items in the lobby space 21L. Pressure adjustment unit 80 makes the pressure in living space 21M smaller than the pressure in lobby space 21L and passageway 9, thereby preventing the atmosphere in living space 21M from leaking out to lobby space 21L. This effectively prevents the spread of infectious diseases. In this way, by using the second door 52 to separate the main room 21 and the auxiliary room 22 under normal circumstances, and forming a lobby space 21L when accommodating infectious disease patients, it is possible to effectively utilize the limited space on board while preventing the spread of infectious diseases. As a result, it is possible to effectively prevent the spread of infection and make effective use of the limited space on board.

[0053] In the above embodiment, the bed 107 in the first cabin 10A and the bed 107 in the second cabin 10B are arranged one above the other, thereby reducing the area occupied by the first cabin 10A and the second cabin 10B. Therefore, it is possible to configure a cabin 10 that ensures livability in the cabin 10 while making effective use of the limited space on board and effectively suppressing the spread of infection.

[0054] In the above embodiment, the pressure adjusting unit 80 adjusts at least one of the supply pressure and the exhaust pressure in each of the first supply and exhaust duct 81, the second supply and exhaust duct 82, and the third supply and exhaust duct 83. This makes it possible to adjust the pressure in the aisle 9, the lobby space 21L, and the living space 21M. Therefore, when an infectious disease patient is accommodated in the living space 21M of the cabin 10, the pressure in the aisle 9, the lobby space 21L, and the living space 21M can be adjusted so that the pressure in the living space 21M is lower than the pressure in the lobby space 21L and the aisle 9.

[0055] In the above embodiment, the second door 52 is provided to be rotatable around the shaft 52s extending in the vertical direction Dv, which allows the compartment to be sealed with a higher degree of airtightness than when the second door 52 is of a sliding type.

[0056] In the above embodiment, by sandwiching the seal member 57 between the door body 55 and the door frame 56 in the second door 52, it is possible to achieve a higher degree of airtightness in the compartment when the door body 55 is closed.

[0057] In the above embodiment, second door 52 is provided with transmission section 59. This allows transmission from lobby space 21L to living space 21M when second door 52 is placed in second position P2. Therefore, the condition of the infectious disease patient in living space 21M can be confirmed from the lobby space 21L side.

[0058] In the above embodiment, a foldable table 110 is provided on a wall surface within the lobby space 21L. With this, when the second door 52 is placed in the second position P2 and the lobby space 21L is formed between the first door 51 and the second door 52, various items such as meals can be handed over via the table 110 between an infected patient in the living space 21M and staff on the aisle 9 side. Because the table 110 is foldable, by folding it up when not in use, the table 110 does not get in the way when entering or exiting the cabin 10.

[0059] (Other embodiments) The above describes in detail the embodiments of the present disclosure with reference to the drawings, but the specific configuration is not limited to this embodiment, and design changes and the like are also included within the scope that does not deviate from the gist of the present disclosure. In the above embodiment, the bed 107A in the first cabin 10A and the bed 107B in the second cabin 10B are arranged so that they entirely overlap when viewed from above, but this is not limited to this. It is sufficient that the bed 107A in the first cabin 10A and the bed 107B in the second cabin 10B at least partially overlap when viewed from above.

[0060] In the above embodiment, the auxiliary compartment 22 is arranged on the side of the intermediate partition wall 14 in the aisle longitudinal direction De. In other words, the auxiliary compartment 22 of the first cabin 10A and the auxiliary compartment 22 of the second cabin 10B are arranged on both sides of the intermediate partition wall 14. Alternatively, the auxiliary compartment 22 may be arranged on the partition wall 13 in the aisle longitudinal direction De. In this case, the first portion 21a of the main compartment 21 of the first cabin 10A and the first portion 21a of the second cabin 10B are arranged on both sides of the intermediate partition wall 14.

[0061] In the above embodiment, the arrangement of the fixtures provided in the main cabin 21 and the arrangement of the toilet 101 and shower room 102 in the antechamber 22 has been described, but the arrangement can be changed as appropriate. Furthermore, fixtures other than those described above may be provided, or some of the fixtures described above may be omitted. For example, the bed 107A in the first cabin 10A and the bed 107B in the second cabin 10B may be arranged so that they do not overlap at least partially when viewed from above.

[0062] In addition, in the above embodiment, the cabins 10 normally used by the crew of the ship 1 are repurposed to accommodate infectious disease patients in the event of an infectious disease outbreak, but this is not limited to this. The cabins 10 normally used by the passengers of the ship 1 may also be repurposed to accommodate infectious disease patients. In this case, the configuration, furnishings, etc. of the cabins 10 may be different from those shown in the above embodiment.

[0063] In the above embodiment, the second door 52 is provided with the sealing member 57 and the transmitting portion 59, but the first door 51 may also be provided with the sealing member 57 and the transmitting portion 59.

[0064] In addition, in the above embodiment, the floating body is exemplified as a ship 1 that can navigate using a main engine or the like, but the present disclosure is not limited to this. The configuration of the present disclosure can also be applied to a floating body that does not have a power source for navigation, for example.

[0065] <Additional Notes> The floating body 1 described in the embodiment can be understood, for example, as follows.

[0066] (1) A float 1 according to the first aspect comprises a float body 2, a passage 9 provided within the float body 2, a plurality of cabins 10 arranged along the passage 9 and each having a main room 21 and an auxiliary room 22, a first door 51 arranged to separate the passage 9 from the cabins 10, a second door 52 that can be opened and closed between a first position P1 that separates the cabin 10 into the main room 21 and the auxiliary room 22 and a second position P2 that separates the cabin 10 into a lobby space 21L on the passage 9 side and a living space 21M away from the passage 9, and a pressure adjustment unit 80 that can adjust the pressure in the passage 9, the lobby space 21L, and the living space 21M so that the pressure in the living space 21M is smaller than the pressure in the lobby space 21L and the passage 9. Examples of the floating body 1 include a ship and a floating structure.

[0067] The float 1 has a plurality of cabins 10 arranged along a passage 9 provided within the float body 2. Each cabin 10 can be separated from the passage 9 by a first door 51. A second door 52 is provided within each cabin 10. The second door 52 can be opened and closed between a first position P1 and a second position P2. When the second door 52 is positioned at the first position P1, the second door 52 can divide the cabin 10 into a main room 21 and an auxiliary room 22. When the second door 52 is positioned at the second position P2, the second door 52 can divide the cabin 10 into a lobby space 21L on the passage 9 side and a living space 21M away from the passage 9. As a result, the first door 51, the second door 52, and the lobby space 21L are present between the passage 9 and the living space 21M, ensuring isolation between the passage 9 and the living space 21M. Furthermore, a lobby space 21L is formed between the first door 51 and the second door 52, allowing various items such as meals to be handed over to an infected patient in the living space 21M via the lobby space 21L. For example, a staff member who has brought a meal or other items through the corridor 9 can enter the lobby space 21L by opening the first door 51. At this time, by positioning the second door 52 at the second position P2, contact between the staff member and the infectious disease patient in the living space 21M can be reduced. After the staff member places the meal or other items in the lobby space 21L and exits from the lobby space 21L to the corridor 9, the infectious disease patient in the living space 21M can receive the items in the lobby space 21L by opening the second door 52 from the second position P2. At this time, by keeping the first door 51 closed, contact between the infectious disease patient and the staff member passing through the corridor 9 can be reduced. Pressure adjustment unit 80 makes the pressure in living space 21M smaller than the pressure in lobby space 21L and passageway 9, thereby preventing the atmosphere in living space 21M from leaking out to lobby space 21L. This effectively prevents the spread of infectious diseases. In this way, by using the second door 52 to separate the main room 21 and the auxiliary room 22 under normal circumstances, and forming a lobby space 21L when accommodating infectious disease patients, it is possible to effectively utilize the limited space on board while preventing the spread of infectious diseases. As a result, it is possible to effectively prevent the spread of infection and make effective use of the limited space on board.

[0068] (2) The float 1 of the second aspect is the float 1 of (1), wherein each of the multiple cabins 10 is provided with a bed 107 in the main cabin 21, and among the multiple cabins 10, the bed 107 of either the first cabin 10A or the second cabin 10B that are adjacent in the direction De in which the passage 9 extends is arranged in the upper part of the cabin 10, and the bed 107 of the other of the first cabin 10A and the second cabin 10B is arranged in the lower part of the cabin 10, and at least a portion of the bed 107 of the first cabin 10A and the bed 107 of the second cabin 10B are arranged so as to overlap when viewed from above.

[0069] In this way, by arranging the bed 107 in the first cabin 10A and the bed 107 in the second cabin 10B one on top of the other, it is possible to reduce the area occupied by the first cabin 10A and the second cabin 10B. Therefore, it is possible to configure a cabin 10 that ensures livability in the cabin 10 while making effective use of the limited space on board and effectively suppressing the spread of infection.

[0070] (3) The float 1 of the third aspect is the float 1 of (1) or (2), which comprises a first intake and exhaust duct 81 for supplying and exhausting air to the passage 9, a second intake and exhaust duct 82 for supplying and exhausting air to the lobby space 21L, and a third intake and exhaust duct 83 for supplying and exhausting air to the living space 21M, and the pressure adjustment unit 80 adjusts the pressure in the passage 9, the lobby space 21L, and the living space 21M by adjusting at least one of the intake and exhaust pressure in the first intake and exhaust duct 81, the second intake and exhaust duct 82, and the third intake and exhaust duct 83.

[0071] As a result, the pressure adjustment unit 80 can adjust the pressure in the aisle 9, the lobby space 21L, and the living space 21M by adjusting at least one of the supply pressure and the exhaust pressure in each of the first supply and exhaust duct 81, the second supply and exhaust duct 82, and the third supply and exhaust duct 83. As a result, when an infectious disease patient is accommodated in the living space 21M of the cabin 10, the pressure in the aisle 9, the lobby space 21L, and the living space 21M can be adjusted so that the pressure in the living space 21M is lower than the pressure in the lobby space 21L and the aisle 9.

[0072] (4) The float 1 according to the fourth aspect is any one of the floats 1 of (1) to (3), in which the second door 52 is rotatable around an axis 52s extending in the vertical direction Dv.

[0073] This allows the compartment to be sealed with a higher degree of airtightness than when the second door 52 is of a sliding type.

[0074] (5) The float 1 according to the fifth aspect is the float 1 of (4), wherein the second door 52 further comprises a door body 55 rotatably arranged around an axis extending in the vertical direction Dv, a door frame 56 arranged along the outer periphery of the door body 55, and a sealing member 57 sandwiched between the outer periphery of the door body 55 and the door frame 56.

[0075] As a result, by sandwiching the seal member 57 between the door body 55 and the door frame 56 in the second door 52, it is possible to achieve a compartmentalization with a higher degree of airtightness when the door body 55 is closed.

[0076] (6) The float 1 according to the sixth aspect is any one of the floats 1 of (1) to (5), in which the second door 52 has a transparent portion 59 that allows transmission from the lobby space 21L side to the living space 21M side.

[0077] This allows for visibility from the lobby space 21L side to the living space 21M side when the second door 52 is placed in the second position P2. Therefore, the condition of the infectious disease patient in the living space 21M can be confirmed from the lobby space 21L side.

[0078] (7) The floating body 1 according to a seventh aspect is any one of the floating bodies 1 according to (1) to (6), and is provided with a foldable table 110 on a wall surface within the lobby space 21L.

[0079] As a result, with second door 52 located at second position P2 and lobby space 21L formed between first door 51 and second door 52, various items such as meals can be handed over between infected patients in living space 21M and staff on the aisle 9 side via table 110. Since table 110 is foldable, by folding it up when not in use, table 110 can be prevented from getting in the way when entering or exiting cabin 10. [Explanation of symbols]
