Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the prefabricated private room of Patent Document 1 has a problem that it is difficult to secure a storage place for the purpose of stockpiling because the maximum dimension in the storage state is approximately the same as the height dimension of the prefabricated private room and is long, and it is difficult to carry.

[0005] An object of the present invention is to provide a prefabricated private room that is easy to assemble and can make the maximum dimension in the storage state smaller than the height dimension of the prefabricated private room.

Means for Solving the Problems

[0006] (1) The first invention is a prefabricated private room comprising four walls that form a rectangular cylindrical shape when assembled, with a door provided on the front wall of the four walls, wherein each of the four walls consists of a lower member and an upper member that are arranged vertically in the assembled state and are detachably connected by a plurality of connectors or connected to each other via a plurality of hinges, and at least two of the four walls are foldable wall members consisting of the lower member and the upper member connected to each other via the plurality of hinges, wherein adjacent lower members are detachably connected by a plurality of connectors or connected via a plurality of hinges, and adjacent upper members are detachably connected by a plurality of connectors or connected via a plurality of hinges, wherein the four walls can be separated into four or fewer parts by removing all the connectors, and each of the parts includes one of the foldable wall members and can be folded by bending all of the hinges included in the part.

[0007] With this configuration, each wall consists of a lower and upper member, allowing the maximum dimensions of each part obtained by separating the four walls to be smaller than the height of the modular compartment. This reduces storage space constraints, making it easier to secure storage space and facilitating transport. Furthermore, since each part includes a foldable wall member, there are no parts consisting only of an upper or lower member, thus minimizing the increase in the number of parts. This reduces the number of connection points during assembly, making the assembly process easier.

[0008] (2) The second aspect of the present invention is a prefabricated private room comprising four walls forming a rectangular cylindrical shape when assembled, a door provided on the front wall of the four walls, and in the assembled state, the front-to-back length of two of the four side walls being longer than the left-to-right length of the front and rear walls, wherein each of the side walls is arranged in the front-to-back direction when assembled and consists of a front side member and a rear side member that are separated and connected to each other by a plurality of connectors, or connected to each other by a plurality of hinges, and each of the front wall, the rear wall, the front side member and the rear side member of the two side walls is arranged in the vertical direction when assembled and separated and connected to each other by a plurality of connectors, or connected to each other by a plurality of hinges The four walls consist of a front wall, a rear wall, and at least two of the front and rear side wall members of the two side walls are foldable wall members consisting of a lower member and an upper member connected to each other via a plurality of hinges, wherein adjacent lower members are detachably connected to each other by a plurality of connectors or connected via a plurality of hinges, and adjacent upper members are detachably connected to each other by a plurality of connectors or connected via a plurality of hinges, and the four walls are separated into six or fewer parts by removing all the connectors, each of which includes one foldable wall member and is folded by bending all the hinges included in the part.

[0009] With this configuration, the front wall, rear wall, and the front and rear side wall members of each side wall consist of a lower and upper member, respectively. This allows the maximum dimensions of each part obtained by separating the four walls in a folded state to be smaller than the height of the modular compartment. Therefore, even with modular compartments that have a large length in the front-to-back direction, storage space constraints are alleviated, making it easier to secure storage space and to transport. Furthermore, since each part includes a foldable wall member, there are no parts consisting only of an upper member or only a lower member, thus suppressing an increase in the number of parts. As a result, there are fewer connection points during assembly, making the assembly process easier.

[0010] (3) The first or second prefabricated private room of the present invention may further have the following configuration: Each of the at least two folding wall members corresponds to at least one of the following: a first folding wall member, a second folding wall member, and a third folding wall member, wherein the lower member and the upper member of the first folding wall member are detachably connected to the lower member and the upper member adjacent to one side of the first folding wall member by the plurality of connectors, respectively, the lower member and the upper member adjacent to one side of the first folding wall member are detachably connected to each other by the plurality of connectors, or connected to each other via the plurality of hinges, and the lower member and the upper member of the second folding wall member are detachably connected to the lower member and the upper member adjacent to one side of the second folding wall member The lower and upper members adjacent to one side of the second folding wall member are connected via the plurality of hinges and are detachably connected to each other by the plurality of connectors, one of the lower and upper members of the third folding wall member is detachably connected to one of the lower and upper members adjacent to one side of the third folding wall member by the plurality of connectors, the other of the lower and upper members of the third folding wall member is connected via the plurality of hinges to the other of the lower and upper members adjacent to one side of the third folding wall member, and the lower and upper members adjacent to one side of the third folding wall member are detachably connected to each other by the plurality of connectors.

[0011] (4) In the first or second prefabricated private room of the present invention, the front wall may be the folding wall member.

[0012] With this configuration, since the front wall is a foldable wall component, there is no need to separate the components that support the door so that it can be opened and closed into upper and lower parts, which simplifies the structure of the front wall and makes it lighter.

[0013] (5) The first or second modular cubicle of the present invention may have the following configuration: Each of the lower members has a lower panel made of corrugated plastic, each of the upper members has an upper panel made of corrugated plastic, each of the lower members of the foldable wall member has a lower frame portion that supports the lower panel in addition to the lower panel, each of the upper members of the foldable wall member has an upper frame portion that supports the upper panel in addition to the upper panel, the plurality of hinges that connect the lower and upper members of each foldable wall member to each other are provided on the lower frame portion and the upper frame portion, and the lower panel and upper panel of each foldable wall member are detachably connected to each other and are separated when the part including the foldable wall member is folded.

[0014] This configuration allows for a lightweight, modular cubicle, as all lower and upper components are made of corrugated plastic panels, making assembly and transport easy. Furthermore, since corrugated plastic is water-resistant, it can be used outdoors. Furthermore, since the lower and upper members of the folding wall member each have a frame that supports the panel, the rigidity of the folding wall member can be increased. In addition, since a hinge connecting the lower and upper members of the folding wall member is provided on the frame, even if a large load is applied to the hinge when folding the folding wall member, damage to the panel due to that load can be suppressed.

[0015] (6) The first or second prefabricated private room of the present invention may have the following configuration in addition to the configuration of (5) above: In each pair of lower members and upper members arranged vertically in the assembled state, one of the lower members and the upper member includes an intermediate horizontal plate that extends horizontally and covers the upper end of the lower panel and the lower end of the upper panel in the assembled state, and the other of the lower member and the upper member is detachably connected to the intermediate horizontal plate.

[0016] In this configuration, the lower panel and the upper panel are connected using an intermediate horizontal plate that covers their ends, thereby increasing the rigidity of the wall having the intermediate horizontal plate.

[0017] (7) The first or second prefabricated private room of the present invention may have the following configuration in addition to the configuration of (5) above: Each lower frame portion includes two lower support columns arranged on both sides in the horizontal direction when the lower panel is assembled, and each upper frame portion includes two upper support columns arranged on both sides in the horizontal direction when the upper panel is assembled, and two hinges connecting the lower and upper members of each folding wall member are provided on the two lower and two upper support columns.

[0018] In this configuration, the rigidity of the folding wall member is increased because the lower and upper frames of the folding wall member each have two support columns positioned on both sides of the panel in the horizontal direction.

[0019] (8) The first or second prefabricated private room of the present invention may have the following configuration in addition to the configuration of (7) above: The front wall is the folding wall member, and the lower panel and upper panel of the front wall constitute at least a part of the door, the lower panel of the front wall is connected to one of the two lower pillars of the front wall via a plurality of hinges for opening and closing the door, and the upper panel of the front wall is connected to one of the two upper pillars of the front wall via a plurality of hinges for opening and closing the door.

[0020] With this configuration, hinges connecting the lower and upper members, and hinges for opening and closing the door are provided on the support columns of the front wall, thus simplifying the structure of the front wall and reducing its weight.

[0021] (9) The assembled private room of the first or second aspect of the present invention may have the following configuration in addition to the configuration of (8) above. A first rotation lock mechanism provided on the lower support column on the left side and the upper support column on the left side of the front wall, which restricts the relative rotation between the lower support column and the upper support column; and at least one of a second rotation lock mechanism provided on the lower support column on the right side and the upper support column on the right side of the front wall, which restricts the relative rotation between the lower support column and the upper support column.

[0022] According to this configuration, the relative rotation between the lower support column and the upper support column of the front wall can be restricted. Therefore, the rigidity of the front wall can be increased, and the assembly work and disassembly work can be facilitated.

[0023] (10) The assembled private room of the first or second aspect of the present invention may have the following configuration in addition to the configuration of (9) above. The first rotation lock mechanism includes a first rotating member provided rotatably about a horizontal axis in the assembled state on one of the lower support column on the left side and the upper support column on the left side of the front wall and having a recess, and a first protrusion provided on the other of the lower support column on the left side and the upper support column on the left side of the front wall and fitting into the recess of the first rotating member. The second rotation lock mechanism includes a second rotating member provided rotatably about a horizontal axis in the assembled state on one of the lower support column on the right side and the upper support column on the right side of the front wall and having a recess, and a second protrusion provided on the other of the lower support column on the right side and the upper support column on the right side of the front wall and fitting into the recess of the second rotating member.

[0024] According to this configuration, since the first rotation lock mechanism and the second rotation lock mechanism are constituted by the rotating member and the protrusion, the relative rotation between the lower support column and the upper support column of the front wall can be restricted with a simple configuration.

[0025] (11) The assembled private room of the first or second invention of the present invention may have the following configuration in addition to the configuration of (8) above. The lower member of the front wall has, in addition to the lower panel and the lower frame portion, a lower reinforcing member fixed to the lower panel, and the upper member of the front wall has, in addition to the upper panel and the upper frame portion, an upper reinforcing member fixed to the upper panel. The lower reinforcing member and the upper reinforcing member extend in the vertical direction in the assembled state, are arranged side by side in the vertical direction, and are separably connected to each other.

[0026] According to this configuration, since the lower member and the upper member of the front wall each have a reinforcing member, the rigidity of the door can be increased.

[0027] (12) The assembled private room of the first or second invention of the present invention may further include a ceiling member installed at the upper ends of the four walls.

[0028] According to this configuration, since the assembled private room has a ceiling member, it can be used outdoors.

[0030] The prefabricated private room 1 according to the first embodiment of the present invention will be described with reference to Figures 1 to 12. First, the prefabricated private room 1 in its assembled state will be described using the front, back, left, and right directions shown in Figure 1, etc. As shown in Figure 1, the prefabricated private room 1 comprises a main body 2 that forms a rectangular cylindrical shape in its assembled state, and a ceiling member 3 installed at the upper end of the main body 2. The main body 2 is composed of a front wall 10, a rear wall 30, and two side walls 40. The two side walls 40 are formed symmetrically. As will be described in detail later, the main part of the prefabricated private room 1 is made of corrugated plastic. Corrugated plastic is a thermoplastic resin sheet material with a structure in which a plurality of partition walls are arranged between two parallel sheets. The plurality of partition walls may be arranged perpendicular to the sheets, or they may be arranged in a corrugated pattern. The prefabricated private room 1 has, for example, a length of about 1 m in the left-right direction, a length of about 1 m in the front-back direction, and a height of about 2 m. The prefabricated private room 1 may be used as a toilet booth by, for example, placing a manhole toilet or a portable toilet inside. Furthermore, the prefabricated private room 1 may be used as a changing room or nursing room in evacuation shelters during disasters. Since the prefabricated private room 1 has a ceiling member 3, it can be used outdoors, but it may also be used indoors.

[0031] The ceiling member 3 is detachably connected to each side wall 40 by two eye bolts 4. A rope attached to the ring of each eye bolt 4 is attached to a hook provided on the installation surface of the prefabricated room 1. This prevents the prefabricated room 1 from tipping over. As shown in Figure 2, the ceiling member 3 is a rectangular box shape with an opening at the bottom. The ceiling member 3 is positioned above the front wall 10 and the rear wall 30. The front wall 10 is higher than the rear wall 30. Therefore, the ceiling member 3 is sloped so that it becomes lower towards the rear. This allows rainwater to fall to the rear. The ceiling member 3 is made of corrugated plastic. Note that if the prefabricated room 1 is used indoors, the ceiling member 3 does not need to be installed.

[0032] Next, the details of the front wall 10 will be described. As shown in Figures 3 and 4, the front wall 10 consists of a lower front wall member 10a and an upper front wall member 10b arranged side by side in the vertical direction. The lower front wall member 10a has a lower front wall frame portion 11a, a lower front wall panel 21a, an intermediate front wall horizontal plate 22a, a lower reinforcing member 25a, and edge covers 23a and 24a. The upper front wall member 10b has an upper front wall frame portion 11b, an upper front wall panel 21b, an upper reinforcing member 25b, and edge covers 23b and 24b. As will be described in detail later, the lower front wall panel 21a, the upper front wall panel 21b, the edge covers 23a, 23b, 24a, 24b, the intermediate front wall horizontal plate 22a, the lower reinforcing member 25a, and the upper reinforcing member 25b constitute the door 20. The lower front wall panel 21a and the upper front wall panel 21b are made of corrugated plastic. The front wall lower frame portion 11a, the front wall upper frame portion 11b, the front wall intermediate horizontal plate 22a, the lower reinforcing member 25a, the upper reinforcing member 25b, and the edge covers 23a, 23b, 24a, and 24b are formed of a metal such as an aluminum alloy.

[0033] The front wall lower frame section 11a has two front lower support columns 12a and a door lower frame 13a. The front wall upper frame section 11b has two front upper support columns 12b and a door upper frame 13b. The two front lower support columns 12a are positioned at both the left and right ends of the front wall 10. The door lower frame 13a is fixed to the lower ends of the two front lower support columns 12a and extends in the left and right directions. In this specification, "fixed" means a joint (connection) that is not removed when the modular cubicle 1 is disassembled and folded. Also in this specification, the end of a part means the part that is combined with the end of the part and its vicinity. The two front lower support columns 12a and the door lower frame 13a are positioned on the installation surface of the modular cubicle 1. The door lower frame 13a is positioned below the door 20. The modular cubicle 1 does not necessarily have to have a door lower frame 13a. The two front upper support columns 12b are positioned at both the left and right ends of the front wall 10. The two front upper support columns 12b are positioned on top of the two front lower support columns 12a. The door upper frame 13b is fixed to the upper ends of the two front upper support columns 12b and extends in the left and right directions. The door upper frame 13b is positioned above the door 20. The front portion of the ceiling member 3 is installed on top of the door upper frame 13b.

[0034] The two front lower supports 12a are formed approximately symmetrically. The two front upper supports 12b are also formed approximately symmetrically. As shown in Figure 5, the front upper supports 12b have a rectangular prism 121b with a rectangular cross-section and a vertical plate portion 122b that protrudes rearward from the rectangular prism 121b. As shown in Figure 2, the vertical plate portion 122a extends in the vertical direction. The front lower supports 12a, like the front upper supports 12b, have a rectangular prism 121a and a vertical plate portion 122a.

[0035] As shown in Figure 3, the right front lower support 12a and the right front upper support 12b are connected via a hinge 14, and the left front lower support 12a and the left front upper support 12b are connected via a hinge 14. In this way, the front wall lower member 10a and the front wall upper member 10b are connected via two hinges 14. In other words, the front wall upper member 10b is rotatably connected to the front wall lower member 10a via two hinges 14.

[0036] As shown in Figure 6, the front wall 10 has a first rotation locking mechanism 50L and a second rotation locking mechanism 50R on its rear surface. The first rotation locking mechanism 50L is provided at the upper end of the left front lower support 12a and the lower end of the left front upper support 12b. The second rotation locking mechanism 50R is provided at the upper end of the right front lower support 12a and the lower end of the right front upper support 12b. The first rotation locking mechanism 50L has a first rotating member 51L and a first projection 52L. The first rotating member 51L is provided on the rear surface of the left front lower support 12a so as to be rotatable around an axis parallel to the front-rear direction. The first rotating member 51L has a recess 53L that opens in the direction of rotation. The first projection 52L is provided on the rear surface of the left front upper support 12b and fits into the recess 53L of the first rotating member 51L. The second rotation locking mechanism 50R has a second rotating member 51R and a second projection 52R. The second rotating member 51R is provided on the rear surface of the right front lower support 12a so as to be rotatable around an axis parallel to the front-rear direction. The second rotating member 51R has a recess 53R that opens in the direction of rotation. The second projection 52R is provided on the rear surface of the right front upper support 12b and fits into the recess 53R of the second rotating member 51R.

[0037] The first rotation locking mechanism 50L restricts the relative rotation between the left front lower support 12a and the left front upper support 12b. The second rotation locking mechanism 50R restricts the relative rotation between the right front lower support 12a and the right front upper support 12b. As a result, the rigidity of the front wall 10 can be increased, and assembly and disassembly can be made easier. Since the first rotation locking mechanism 50L and the second rotation locking mechanism 50R are composed of rotating members 51L, 51R and projections 52L, 52R, the relative rotation between the front lower support 12a and the front upper support 12b of the front wall 10 can be restricted with a simple configuration. Furthermore, since the rotating members 51L, 51R are provided on opposite sides in the vertical direction for the first rotation locking mechanism 50L and the second rotation locking mechanism 50R, it is possible to prevent the first rotation locking mechanism 50L and the second rotation locking mechanism 50R from disengaging simultaneously.

[0038] Furthermore, the two rotating members 51L and 51R may both be provided on the front lower support column 12a, or both may be provided on the front upper support column 12b. Also, only one of the two rotation locking mechanisms 50L and 50R may be provided. In addition, the mounting positions of the first rotation locking mechanism 50L and the second rotation locking mechanism 50R do not have to be on the rear surfaces of the front lower support column 12a and the front upper support column 12b. In that case, the rotating members 51L and 51R may be rotatable around an axis parallel to the left-right direction. Furthermore, the configuration of the rotation locking mechanisms 50L and 50R is not limited to a configuration using rotating members 51L and 51R and projections 52L and 52R, and is sufficient as long as it can restrict the relative rotation between the front lower support column 12a and the front upper support column 12b. Also, the rotation locking mechanisms 50L and 50R may not be provided at all.

[0039] Next, the details of the door 20's configuration will be described. As shown in Figure 3, the front lower panel 21a is positioned between two front lower posts 12a, and the front upper panel 21b is positioned between two front upper posts 12b. In other words, the two front lower posts 12a are positioned on both sides of the front lower panel 21a in the horizontal direction, and the two front upper posts 12b are positioned on both sides of the front upper panel 21b in the horizontal direction. This increases the rigidity of the front wall 10. The front lower panel 21a is connected to the right front lower post 12a via multiple hinges 15a for opening and closing the door 20, and the front upper panel 21b is connected to the right front upper post 12b via multiple hinges 15b for opening and closing the door 20. This allows the door 20 to be opened and closed. Thus, the support columns of the front wall 10 are provided with hinges 14 that connect the lower front wall member 10a and the upper front wall member 10b, and hinges 15a and 15b for opening and closing the door 20. As a result, the structure of the front wall 10 can be simplified and its weight reduced. Thus, the lower front wall panel 21a is supported by the lower front wall frame portion 11a, and the upper front wall panel 21b is supported by the upper front wall frame portion 11b. As a result, the door 20 is supported by the lower front wall frame portion 11a and the upper front wall frame portion 11b.

[0040] The front wall lower panel 21a and the front wall upper panel 21b are rectangular, and more specifically, approximately square. The lower end of the front wall upper panel 21b contacts the upper end of the front wall lower panel 21a. As shown in Figures 4 and 6, the lower end of the front wall lower panel 21a is covered by edge cover 23a on both sides, the upper end of the front wall upper panel 21b is covered by edge cover 23b on both sides, and the left ends of the front wall lower panel 21a and the front wall upper panel 21b are covered by edge covers 24a and 24b on both sides. The edge covers 23a and 24a are fixed to the front wall lower panel 21a, and the edge covers 23b and 24b are fixed to the front wall upper panel 21b.

[0041] As shown in Figure 3, the front wall intermediate horizontal plate 22a is a flat plate extending horizontally and is fixed to the upper end of the front wall lower panel 21a. The front wall intermediate horizontal plate 22a is positioned on the outside (front side) of the front wall lower panel 21a and the front wall upper panel 21b, covering the upper end of the front wall lower panel 21a and the lower end of the front wall upper panel 21b. The front wall intermediate horizontal plate 22a is detachably connected to the front wall upper panel 21b by a plurality of connectors 26. In other words, the front wall upper panel 21b and the front wall lower panel 21a are detachably connected by the front wall intermediate horizontal plate 22a and the plurality of connectors 26. The connectors 26 can be, for example, a single bolt or a combination of a bolt and a nut, but are not limited to these. The same applies to the connectors 37, 44, 45a, and 45b described later. The position of the upper end of the front wall intermediate horizontal plate 22a in the assembled state is set so that the front wall upper panel 21b and the front wall intermediate horizontal plate 22a do not come into contact when the front wall upper member 10b rotates relative to the front wall lower member 10a. The rigidity of the front wall 10 is increased by connecting the lower panel 21a and the upper panel 21b of the front wall 10 using the front wall intermediate horizontal plate 22a that covers their ends.

[0042] As shown in Figure 6, the lower reinforcing member 25a is positioned behind the front wall lower panel 21a and fixed to the front wall lower panel 21a. The upper reinforcing member 25b is positioned behind the front wall upper panel 21b and fixed to the front wall upper panel 21b. The lower reinforcing member 25a and the upper reinforcing member 25b are both flat plates extending in the vertical direction and are arranged side by side in the vertical direction. The lower end of the upper reinforcing member 25b and the upper end of the lower reinforcing member 25a are detachably connected. In detail, the lower end of the upper reinforcing member 25b extends into the area of ​​the front wall lower panel 21a, and a connecting plate 27 rotatably provided on the upper end of the lower reinforcing member 25a is connected to the lower end of the upper reinforcing member 25b by bolts 28. As described above, the lower reinforcing member 25a and the upper reinforcing member 25b are fixed to the lower front wall panel 21a and the upper front wall panel 21b and connected to each other, thereby reinforcing the lower front wall panel 21a and the upper front wall panel 21b and increasing the rigidity of the door 20. Moreover, since the connection position between the lower front wall panel 21a and the upper front wall panel 21b is offset from the boundary between the lower front wall panel 21a and the upper front wall panel 21b, bending at the boundary between the upper front wall panel 21b and the lower front wall panel 21a is less likely to occur, further increasing the rigidity of the door 20. Note that the connection structure between the upper reinforcing member 25b and the lower reinforcing member 25a is not limited to the above configuration, and any configuration that allows them to be connected in a separable manner is acceptable. The upper reinforcing member 25b and the lower reinforcing member 25a do not necessarily have to be provided.

[0043] As shown in Figure 6, etc., a locking device 29 is provided on the left end of the front wall upper panel 21b and on the left front upper support post 12b. The locking device 29 is a slide lock, but it may also be a rotary lock. The locking device 29 is configured such that the color of the outer indicator part changes when operated from the inside. Multiple hinges 15a and multiple hinges 15b are provided so that the door 20 is in an open state when the locking device 29 is not locked. The outer surface (front) of the door 20 does not have a gripping part, but it may have one. Depending on the vertical length of the front wall lower panel 21a and its installation height, the locking device 29 may also be provided on the front wall lower panel 21a and the front lower support post 12a.

[0044] Next, the details of the rear wall 30's configuration will be described. As shown in Figure 7, the rear wall 30 consists of a lower rear wall member 30a and an upper rear wall member 30b arranged side by side in the vertical direction. The lower rear wall member 30a has a lower rear wall frame portion 34a, a lower rear wall panel 31a, an intermediate rear wall horizontal plate 32a, and an edge cover 33a. The upper rear wall member 30b has an upper rear wall frame portion 34b, an upper rear wall panel 31b, and an edge cover 33b. The lower rear wall panel 31a and the upper rear wall panel 31b are made of corrugated plastic. The lower rear wall frame portion 34a, the upper rear wall frame portion 34b, the intermediate rear wall horizontal plate 32a, and the edge covers 33a and 33b are made of metal, such as aluminum alloy.

[0045] The lower rear wall frame section 34a has two lower rear support columns 35a. The upper rear wall frame section 34b has two upper rear support columns 35b. The two lower rear support columns 35a are positioned at both the left and right ends of the rear wall 30. The two upper rear support columns 35b are positioned at both the left and right ends of the rear wall 30. The two lower rear support columns 35a are positioned on the installation surface of the prefabricated individual room 1. The two upper rear support columns 35b are positioned on top of the two lower rear support columns 35a, respectively.

[0046] As shown in Figure 5, the rear upper support 35b has an L-shaped cross-section, with one side extending inward from the corner of the L-shape (towards the interior of the prefabricated private room 1) and the other side extending forward from the corner of the L-shape. The rear lower support 35a has the same configuration as the rear upper support 35b.

[0047] As shown in Figure 7, the right rear lower support 35a and the right rear upper support 35b are connected via a hinge 36, and the left rear lower support 35a and the left rear upper support 35b are connected via a hinge 36. In this way, the rear wall lower member 30a and the rear wall upper member 30b are connected via two hinges 36.

[0048] The lower rear wall panel 31a is positioned between two lower rear support columns 35a, and the upper rear wall panel 31b is positioned between two upper rear support columns 35b. In other words, the two lower rear support columns 35a are positioned on both sides of the lower rear wall panel 31a in the horizontal direction, and the two upper rear support columns 35b are positioned on both sides of the upper rear wall panel 31b in the horizontal direction. This increases the rigidity of the rear wall 30. The left and right ends of the upper rear wall panel 31b are fixed to the two upper rear support columns 35b, respectively. More specifically, the left and right ends of the upper rear wall panel 31b are positioned on the inside of one side (the inside side of the prefabricated compartment 1) that extends horizontally from the L-shaped upper rear support column 35b, and are fixed to that side. Similarly, the left and right ends of the lower rear wall panel 31a are fixed to the two lower rear support columns 35a, respectively. Thus, the lower rear wall panel 31a is supported by the lower rear wall frame portion 34a, and the upper rear wall panel 31b is supported by the upper rear wall frame portion 34b.

[0049] The rear wall lower panel 31a and the rear wall upper panel 31b are rectangular, and more specifically, approximately square. The lower end of the rear wall upper panel 31b contacts the upper end of the rear wall lower panel 31a. The lower end of the rear wall lower panel 31a is covered on both sides by an edge cover 33a, and the upper end of the rear wall upper panel 31b is covered on both sides by an edge cover 33b. The edge cover 33a is fixed to the rear wall lower panel 31a, and the edge cover 33b is fixed to the rear wall upper panel 31b.

[0050] The rear wall intermediate horizontal plate 32a is fixed to the upper end of the rear wall lower panel 31a and is a flat plate extending horizontally. The rear wall intermediate horizontal plate 32a is positioned outside (rear side) of the rear wall lower panel 31a and the rear wall upper panel 31b, covering the upper end of the rear wall lower panel 31a and the lower end of the rear wall upper panel 31b. The rear wall intermediate horizontal plate 32a is detachably connected to the rear wall upper panel 31b by a plurality of connectors 37. In other words, the rear wall upper panel 31b and the rear wall lower panel 31a are detachably connected by the rear wall intermediate horizontal plate 32a and the plurality of connectors 37. In the assembled state, the position of the upper end of the rear wall intermediate horizontal plate 32a is set so that the rear wall upper panel 31b and the rear wall intermediate horizontal plate 32a do not come into contact when the rear wall upper member 30b rotates relative to the rear wall lower member 30a. The rigidity of the rear wall 30 is increased by connecting the lower panel 31a and the upper panel 31b of the rear wall 30 using the rear wall intermediate horizontal plate 32a that covers their ends.

[0051] Next, the details of the side wall 40's configuration will be described. As shown in Figures 2 and 3, each side wall 40 consists of a lower side wall member 40a and an upper side wall member 40b arranged side by side in the vertical direction. The lower side wall member 40a has a lower side wall panel 41a, an intermediate side wall horizontal plate 42a, and an edge cover 43a. The upper side wall member 40b has an upper side wall panel 41b and an edge cover 43b. The lower side wall panel 41a and the upper side wall panel 41b are made of corrugated plastic. The intermediate side wall horizontal plate 42a and the edge covers 43a and 43b are made of metal, such as aluminum alloy.

[0052] As shown in Figure 2, the lower side wall panel 41a and the upper side wall panel 41b are rectangular, and more specifically, approximately square. The lower end of the upper side wall panel 41b contacts the upper end of the lower side wall panel 41a. The lower end of the lower side wall panel 41a is covered on both sides by an edge cover 43a, and the upper end of the upper side wall panel 41b is covered on both sides by an edge cover 43b.

[0053] The intermediate horizontal plate 42a of the side wall is fixed to the upper end of the lower side wall panel 41a and is a flat plate extending horizontally. The intermediate horizontal plate 42a is positioned outside the lower side wall panel 41a and the upper side wall panel 41b, and covers the upper end of the lower side wall panel 41a and the lower end of the upper side wall panel 41b. The intermediate horizontal plate 42a is detachably connected to the upper side wall panel 41b by a plurality of connectors 44. In other words, the upper side wall panel 41b and the lower side wall panel 41a are detachably connected by the intermediate horizontal plate 42a and the plurality of connectors 44. In this way, the lower side wall member 40a and the upper side wall member 40b are detachably connected by a plurality of connectors 44. The rigidity of the side wall 40 is increased by connecting the lower panel 41a and the upper panel 41b of the side wall 40 using the intermediate horizontal plate 42a that covers their ends.

[0054] The front end of the upper side wall panel 41b is detachably connected to the upper front support column 12b by a plurality of connectors 45b. More specifically, as shown in Figure 5, the front end of the upper side wall panel 41b is positioned inside the vertical plate portion 122b of the upper front support column 12b (on the interior side of the prefabricated private room 1) and is detachably connected to the vertical plate portion 122b by a plurality of connectors 45b. Similarly, the front end of the lower side wall panel 41a is detachably connected to the lower front support column 12a by a plurality of connectors 45a. In this way, the upper side wall member 40b and the upper front wall member 10b are detachably connected by a plurality of connectors 45b, and the lower side wall member 40a and the lower front wall member 10a are detachably connected by a plurality of connectors 45a. The side wall 40 and the front wall 10 are detachably connected by a plurality of connectors 45a, 45b. The front wall 10 corresponds to the first foldable wall member of the present invention.

[0055] As shown in Figures 5 and 7, the upper side wall panel 41b is connected to the upper rear wall panel 31b via a plurality of hinges 46b. The lower side wall panel 41a is connected to the lower rear wall panel 31a via a plurality of hinges 46a. Thus, the upper side wall member 40b and the upper rear wall member 30b are connected via a plurality of hinges 46b, and the lower side wall member 40a and the lower rear wall member 30a are connected via a plurality of hinges 46a. The side wall 40 and the rear wall 30 are connected via a plurality of hinges 46a, 46b. The rear wall 30 corresponds to the second foldable wall member of the present invention.

[0056] As shown in Figure 5, the rear end of the upper side wall panel 41b is positioned inside one side of the L-shaped upper rear support 35b that extends in the front-rear direction. Similarly, the rear end of the lower side wall panel 41a is positioned inside one side of the L-shaped lower rear support 35a that extends in the front-rear direction. The L-shaped upper rear support 35b covers the left-right ends of the upper rear wall panel 31b and the rear end of the upper side wall panel 41b, preventing them from being exposed to the outside.

[0057] Next, we will explain the procedure for disassembling and folding the modular private room 1. Note that when assembling the modular private room 1, follow the reverse procedure below.

[0058] First, remove the four eye bolts 4 that connect the ceiling member 3 and the two side walls 40. Next, separate the main body 2 into two parts, as shown in Figures 8 and 9. Figure 9 is a schematic diagram showing the connection state of the four lower members 10a, 30a, 40a, 40a and the four upper members 10b, 30b, 40b, 40b of the main body 2. In Figure 9, the parts that are connected in a separable manner are shown with thick lines, and the parts that are connected via hinges are marked with the symbol ○. One of the two parts is the front wall 10, and the other part 5 consists of the rear wall 30 and the two side walls 40. Specifically, separate the main body 2 into two parts 10 and 5 by removing the multiple connectors 45a, 45b that connect the front wall 10 and the two side walls 40.

[0059] Next, the bolts 28 connecting the lower reinforcing member 25a and the upper reinforcing member 25b of the front wall 10 are removed. The multiple connectors 26 of the intermediate horizontal plate 22a of the front wall are removed to separate the lower front wall panel 21a and the upper front wall panel 21b. The rotating members 51L and 51R are rotated to release the lock state of the first rotation lock mechanism 50L and the second rotation lock mechanism 50R. Subsequently, as shown in Figure 10, the front wall 10 is bent at the two hinges 14 to overlap the lower front wall member 10a and the upper front wall member 10b.

[0060] Next, for each side wall 40, the multiple connectors 44 that connect the lower side wall member 40a and the upper side wall member 40b are removed. Then, as shown in Figure 11, each side wall 40 is rotated and overlapped with respect to the rear wall 30 via multiple hinges 46a, 46b. The upper side wall panels 41b of the two side walls 40 fit inside the L-shaped upper rear support column 35b. The same applies to the relationship between the lower rear support column 35a and the lower side wall panel 41a. After that, the multiple connectors 37 of the intermediate horizontal plate 32a of the rear wall are removed to separate the lower rear wall panel 31a and the upper rear wall panel 31b. Next, as shown in Figure 12, the two overlapping upper side wall members 40b and the upper rear wall member 30b are rotated and overlapped with respect to the two overlapping lower side wall members 40a and the lower rear wall member 30a via two hinges 36. In this way, part 5 is folded by bending it using hinges 36, 46a, and 46b. Then, the ceiling member 3, the folded front wall 10, the folded part 5, and other accessories are all stored together in a cardboard box or similar container.

[0061] In the first embodiment of the modular compartment 1, since each wall 10, 30, and 40 consists of lower members 10a, 30a, and 40a and upper members 10b, 30b, and 40b, the maximum dimensions of each part 5 and 10 obtained by separating the main body 2 in a folded state can be made smaller than the height dimension of the modular compartment 1. As a result, storage space constraints are eased, making it easier to secure storage space and to carry the compartment. Furthermore, since there are no parts consisting only of upper members or only of lower members, the increase in the number of parts is suppressed. As a result, the number of connection points during assembly is reduced, making the assembly work easier.

[0062] Since the front wall 10 is constructed with a lower member 10a and an upper member 10b connected by a hinge 14, there is no need to separate the members that support the door 20 so that it can be opened and closed into upper and lower parts, thus simplifying the structure of the front wall 10 and making it lighter.

[0063] Since all lower members 10a, 30a, 40a and upper members 10b, 30b, 40b have panels made of corrugated plastic, the modular cubicle 1 can be constructed to be lightweight, making assembly and transport easy. Furthermore, since corrugated plastic is water-resistant, it can be used outdoors. In addition, the front wall 10 has frame parts 11a, 11b that support the panels 21a, 21b, thereby increasing the rigidity of the front wall 10. Also, since the hinges 14 of the front wall 10 are provided on the frame parts 11a, 11b, even if a large load is applied to the hinges 14 when folding the front wall 10, damage to the panels 21a, 21b due to that load can be suppressed. Similarly, the rear wall 30 has frame parts 34a, 34b that support the panels 31a, 31b, thereby increasing the rigidity of the rear wall 30. Furthermore, since the hinges 36 of the rear wall 30 are provided on the frame portions 34a and 34b, even if a large load is applied to the hinges 36 when the rear wall 30 is folded, damage to the panels 31a and 31b due to that load can be suppressed.

[0064] Next, the prefabricated private room 101 of the second embodiment will be described. In the following, the differences from the first embodiment will be mainly described, and components having the same or similar functions as those described in the first embodiment will be denoted by the same reference numerals as in the first embodiment and their descriptions will be omitted.

[0065] First, the prefabricated cubicle 101 in its assembled state will be described with reference to Figure 13. The prefabricated cubicle 101 comprises a main body 102 and a ceiling member 103. The main body 102 consists of a front wall 10, two side walls 140, and a rear wall 30. The two side walls 140 are formed symmetrically. The front-to-back length of each side wall 140 is longer than the left-to-right length of the front wall 10 and the rear wall 30. The prefabricated cubicle 101 of the second embodiment can be used as a toilet booth for wheelchairs. The dimensions of the prefabricated cubicle 101 in plan view are, for example, approximately 1.2m in the left-to-right length and approximately 1.8m in the front-to-back length. The ceiling member 103 is separated into a front portion and a rear portion by hook-and-loop fasteners.

[0066] Each side wall 140 consists of a front side wall member 40C and a rear side wall member 40D, which are arranged side by side in the front-rear direction when assembled. The front side wall member 40C consists of a front lower side wall member 40Ca and a front upper side wall member 40Cb, which are arranged side by side in the vertical direction when assembled. The rear side wall member 40D consists of a rear lower side wall member 40Da and a rear upper side wall member 40Db, which are arranged side by side in the vertical direction when assembled. The front lower side wall member 40Ca has a front lower side wall panel 41Ca, a front intermediate horizontal plate 42Ca, an edge cover 43Ca, and a lower intermediate vertical plate 47Ca. The front upper side wall member 40Cb has a front upper side wall panel 41Cb, an edge cover 43Cb, and an upper intermediate vertical plate 47Cb. The rear lower side wall member 40Da has a rear lower side wall panel 41Da, a rear intermediate horizontal plate 42Da, and an edge cover 43Da. The rear upper side wall member 40Db has a rear upper side wall panel 41Db and an edge cover 43Db. The front lower side wall panel 41Ca, the front upper side wall panel 41Cb, the rear lower side wall panel 41Da, and the rear upper side wall panel 41Db are made of corrugated plastic. The front intermediate horizontal plate 42Ca, the rear intermediate horizontal plate 42Da, the lower intermediate vertical plate 47Ca, the upper intermediate vertical plate 47Cb, and the edge covers 43Ca, 43Cb, 43Da, and 43Db are made of metal, such as aluminum alloy.

[0067] The four panels 41Ca, 41Cb, 41Da, and 41Db of each side wall 140 are rectangular, and more specifically, approximately square. The lower ends of the front lower side wall panel 41Ca and the rear lower side wall panel 41Da are covered by edge covers 43Ca and 43Da, respectively, and the upper ends of the front upper side wall panel 41Cb and the rear upper side wall panel 41Db are covered by edge covers 43Cb and 43Db, respectively.

[0068] Similar to the configuration in the first embodiment in which the intermediate horizontal plate 42a and the upper panel 41b of the side wall are connected by a plurality of connectors 44, the front intermediate horizontal plate 42Ca and the front upper panel 41Cb of the side wall are connected by a plurality of connectors 44C, and the rear intermediate horizontal plate 42Da and the rear upper panel 41Db of the side wall are connected by a plurality of connectors 44D. Therefore, the front lower member 40Ca and the front upper member 40Cb of the side wall are detachably connected by a plurality of connectors 44C, and the rear lower member 40Da and the rear upper member 40Db of the side wall are detachably connected by a plurality of connectors 44D. The rigidity of the side wall 140 is increased by connecting the lower panel 41Ca and upper panel 41Cb of the front side wall member 40C using a front intermediate horizontal plate 42Ca that covers their ends, and connecting the lower panel 41Da and upper panel 41Db of the rear side wall member 40D using a rear intermediate horizontal plate 42Da that covers their ends.

[0069] The lower intermediate vertical plate 47Ca and the upper intermediate vertical plate 47Cb are flat plates that extend vertically in the assembled state and are fixed to the rear ends of the front lower side wall panel 41Ca and the front upper side wall panel 41Cb. The lower intermediate vertical plate 47Ca covers the rear end of the front lower side wall panel 41Ca and the front end of the rear lower side wall panel 41Da, while the upper intermediate vertical plate 47Cb covers the rear end of the front upper side wall panel 41Cb and the front end of the rear upper side wall panel 41Db. The lower intermediate vertical plate 47Ca is detachably connected to the rear lower side wall panel 41Da by a plurality of connectors 48a, and the upper intermediate vertical plate 47Cb is detachably connected to the rear upper side wall panel 41Db by a plurality of connectors 48b. Thus, the front lower side wall member 40Ca and the rear lower side wall member 40Da are detachably connected by a plurality of connectors 48a, and the front upper side wall member 40Cb and the rear upper side wall member 40Db are detachably connected by a plurality of connectors 48b. In other words, the front side wall member 40C and the rear side wall member 40D are detachably connected by a plurality of connectors 48a and 48b. The lower panel 41Ca of the front side wall member 40C and the lower panel 41Da of the rear side wall member 40D are connected using a lower intermediate vertical plate 47Ca that covers their ends, and the upper panel 41Cb of the front side wall member 40C and the upper panel 41Db of the rear side wall member 40D are connected using an upper intermediate vertical plate 47Cb that covers their ends, thereby increasing the rigidity of the side wall 140.

[0070] The front end of the front lower side wall panel 41Ca is connected to the front lower support column 12a by a plurality of hinges 49a, and the front end of the front upper side wall panel 41Cb is connected to the front upper support column 12b by a plurality of hinges 49b. The front lower support column 12a has a rectangular column 121a and does not have the vertical plate portion 122a of the first embodiment. The configuration of the front upper support column 12b is similar. Thus, the front lower side wall member 40Ca and the front lower front wall member 10a are connected by a plurality of hinges 49a, and the front upper side wall member 40Cb and the front upper front wall member 10b are connected by a plurality of hinges 49b. Unlike the first embodiment, the side wall 140 and the front wall 10 are connected by a plurality of hinges 49a, 49b. The front wall 10 of the second embodiment corresponds to the second foldable wall member of the present invention.

[0071] Similar to the first embodiment, the side wall 140 and the rear wall 30 are connected via a plurality of hinges 46a and 46b. More specifically, the rear lower member 40Da of the side wall and the rear lower member 30a of the rear wall are connected via a plurality of hinges 46a, and the rear upper member 40Db of the side wall and the rear upper member 30b of the rear wall are connected via a plurality of hinges 46b.

[0072] Next, we will explain the procedure for disassembling and folding the modular private room 101. Note that when assembling the modular private room 101, follow the reverse procedure below.

[0073] First, the ceiling member 103 is removed from the main body 102, separating the ceiling member 103 into a front and rear section. Next, as shown in Figure 14, the main body 102 is separated into two parts 106 and 107. Figure 14 is a schematic diagram showing the connection state of the six lower members 10a, 30a, 40Ca, 40Ca, 40Da, 40Da and the six upper members 10b, 30b, 40Cb, 40Cb, 40Db, 40Db of the main body 102, and the method of illustration is the same as in Figure 9. Part 106 consists of a front wall 10 and two front side wall members 40C, and part 107 consists of a rear wall 30 and two rear side wall members 40D. Specifically, the main body 102 is separated into two parts 106 and 107 by removing the multiple connectors 48a and 48b that connect the front side wall member 40C and the rear side wall member 40D of each side wall 140.

[0074] The procedure for folding part 107 is the same as the procedure for folding part 5 in the first embodiment. On the other hand, part 106 is folded in the following procedure. For each side wall front member 40C, remove the multiple connectors 44C that connect the side wall front lower member 40Ca and the side wall front upper member 40Cb. Remove the bolts 28 that connect the lower reinforcing member 25a and the upper reinforcing member 25b of the front wall 10. Release the lock state of the two locking mechanisms 50L and 50R of the front wall 10. Next, rotate each side wall front member 40C relative to the front wall 10 via the multiple hinges 49a and 49b to overlap. After that, remove the multiple connectors 26 of the front wall intermediate horizontal plate 22a to separate the front wall lower panel 21a and the front wall upper panel 21b. Next, the two overlapping front upper side wall members 40Cb and front upper front wall member 10b are rotated and overlapped with the two overlapping front lower side wall members 40Ca and front lower front wall member 10a via the two hinges 14. In this way, part 106 is folded by bending it with hinges 14, 49a, and 49b. Then, the ceiling member 103, the two folded parts 106 and 107, and other accessories are stored together in a cardboard box or the like.

[0075] In the second embodiment of the modular compartment 101, the front wall 10, the rear wall 30, and the front side wall members 40C and rear side wall members 40D of each side wall 140 consist of a lower member and an upper member, respectively. Therefore, the maximum dimensions of each part 106 and 107 in the folded state can be made smaller than the height dimension of the modular compartment 101. As a result, even with a modular compartment 101 that has a large length in the front-to-back direction, the constraints on storage space are alleviated, making it easier to secure storage space and to carry. Furthermore, since there are no parts consisting only of an upper member or only of a lower member, the increase in the number of parts is suppressed. As a result, the number of connection points during assembly is reduced, making the assembly work easier. Other than that, the same effects as in the first embodiment can be obtained for the same configuration as in the first embodiment.

[0076] Although preferred embodiments of the present invention have been described above, the present invention is not limited to the first and second embodiments described above, and various modifications are possible as long as they are described in the claims for utility model registration.

[0077] In the first and second embodiments, the intermediate horizontal plates 22a, 32a, 42a, 42Ca, and 42Da are fixed to the lower panels 21a, 31a, 41a, 41Ca, and 41Da, but they may also be fixed to the upper panels 21b, 31b, 41b, 41Cb, and 41Db and detachably connected to the lower panels 21a, 31a, 41a, 41Ca, and 41Da. In the second embodiment, the intermediate vertical plates 47Ca and 47Cb are fixed to the front panels 41Ca and 41Cb, but they may also be fixed to the rear panels 41Da and 41Db and detachably connected to the front panels 41Ca and 41Cb.

[0078] In the first and second embodiments, the main parts of each upper and lower member are formed from plastic corrugated cardboard, but the main parts of each upper and lower member may be formed from metal such as stainless steel, or from wood. If wood is used, the entire structure may be made of wood, or the panel may be made of wood and the frame supporting the panel may be made of metal.

[0079] As an example of a modification of the first embodiment, as shown in Figure 15, the main body 2 may be configured to be separated into four parts: a front wall 10, a rear wall 30, and two side walls 40. In this case, the front wall 10, the rear wall 30, and the side walls 40 each correspond to the first foldable wall member of the present invention. Furthermore, as an example of a modification of the second embodiment, the main body 102 may be configured to be separated into six parts: a front wall 10, a rear wall 30, two front side wall members 40C, and two rear side wall members 40D. In this case, the front wall 10, the rear wall 30, the two front side wall members 40C, and the two rear side wall members 40D each correspond to the first foldable wall member of the present invention.
