Summary of the Invention

Problems to be Solved by the Invention

[0004] In a prefabricated Japanese-style room as described in Patent Document 1, when it is desired to create a space as if on a stage in the indoor space, it is necessary to remove the panel from the framework and set it up around the framework using a stand. Therefore, when it is desired to create a space as if on a stage in the indoor space, it is necessary to take time and effort.

[0008] <One example of a prefabricated Japanese-style room> The following describes one embodiment of a prefabricated Japanese-style room with reference to the drawings. Note that the drawings may be enlarged in some cases for ease of understanding. The dimensional ratios of the components may differ from those in the actual components or those shown in other drawings.

[0009] <About the framework> As shown in Figure 1, the prefabricated Japanese-style room 10 is equipped with a frame 20. The frame 20 includes a base 21, a number of columns 22, and a number of horizontal members 23.

[0010] The base 21 is installed, for example, on the floor of a room. The base 21 is rectangular in plan view. The length of the longer side of the base 21 is approximately 4 / 3 times the length of the shorter side of the base 21. In the following explanation, the axis along the direction in which the long side of the base 21 extends will be called the first axis X. The axis along the direction in which the short side of the base 21 extends will be called the second axis Y. The axis perpendicular to both the first axis X and the second axis Y will be called the third axis Z. Furthermore, one direction along the first axis X will be called the first positive direction X1, and the direction opposite to the first positive direction X1 will be called the first negative direction X2. One direction along the second axis Y will be called the second positive direction Y1, and the direction opposite to the second positive direction Y1 will be called the second negative direction Y2. One direction along the third axis Z will be called the upward direction Z1, and the direction opposite to the upward direction Z1 will be called the downward direction Z2.

[0011] Multiple columns 22 rise upward from the base 21 in the direction Z1. The columns 22 are rectangular prisms. The columns 22 extend along the third axis Z. The dimension of the columns 22 in the direction along the third axis Z is greater than half the dimension of the shorter side of the base 21. In this embodiment, there are six columns 22. Hereafter, when it is necessary to distinguish between the columns 22, they will be referred to as columns 22A to 22F, respectively.

[0012] Column 22A is located at the corner of the base 21 on the first positive direction X1 side and the second positive direction Y1 side. Column 22B is located at the corner of the base 21 on the first negative direction X2 side and the second positive direction Y1 side. Column 22C is located at the corner of the base 21 on the first positive direction X1 side and the second negative direction Y2 side. Column 22D is located at the corner of the base 21 on the first negative direction X2 side and the second negative direction Y2 side. Column 22E is located in the center of the base 21 on the short side on the first positive direction X1 side and along the second axis Y. Column 22F is located in the center of the base 21 on the short side on the first negative direction X2 side and along the second axis Y. Thus, the six columns 22 are connected to the four corners of the base 21 and to the centers of each of the two short sides of the base 21. Furthermore, the dimensions of all six columns 22 in the direction along the third axis Z are identical.

[0013] The frame 20 has multiple horizontal members 23, consisting of two girders 23A, two beams 23B, and one intermediate beam 23C. The girders 23A extend along the first axis X. One of the two girders 23A connects the end of the upward Z1 direction at column 22A to the end of the upward Z1 direction at column 22B. The other of the two girders 23A connects the end of the upward Z1 direction at column 22C to the end of the upward Z1 direction at column 22D.

[0014] Beam 23B extends along the second axis Y. Therefore, beam 23B is perpendicular to both column 22 and girder 23A. One of the two beams 23B connects the end of the upward Z1 direction in column 22A to the end of the upward Z1 direction in column 22C. The other of the three beams 23B connects the end of the upward Z1 direction in column 22B to the end of the upward Z1 direction in column 22D. Therefore, these two beams 23B are connected to both column 22 and girder 23A.

[0015] The intermediate beam 23C connects the center of one girder 23A in the direction along the first axis X to the center of the other girder 23A in the direction along the first axis X. Therefore, this intermediate beam 23C is not directly connected to the column 22.

[0016] The framework 20 configured as described above has a plurality of frames 20A to 20D into which a panel 40 to be described later can be fitted. As shown in FIG. 2, the frame 20A is composed of a base 21, a column 22A, a column 22E, and a beam 23B connecting the columns 22A and 22E. That is, the frame 20A is on the short side on the first positive direction X1 side of the base 21 and is located on the second positive direction Y1 side when viewed from the center of the base 21. Also, when the framework 20 is viewed in the first negative direction X2, the outer shape of the frame 20A is a rectangular shape that is long in the direction along the third axis Z. The dimension of the frame 20A in the direction along the second axis Y is the distance between the columns 22A and 22E. The dimension of the frame 20A in the direction along the third axis Z is the distance between the base 21 and the beam 23B.

[0017] As shown in FIG. 3, the frame 20B is composed of a base 21, a column 22B, a column 22F, and a beam 23B connecting the columns 22B and 22F. That is, the frame 20B is on the short side on the first negative direction X2 side of the base 21 and is located on the second positive direction Y1 side when viewed from the center of the base 21. Also, when the framework 20 is viewed in the first positive direction X1, the outer shape of the frame 20B is a rectangular shape that is long in the direction along the third axis Z. The dimension of the frame 20B in the direction along the second axis Y is the distance between the columns 22B and 22F. The dimension of the frame 20B in the direction along the third axis Z is the distance between the base 21 and the beam 23B.

[0018] As shown in FIG. 2, the frame 20C is composed of a base 21, a column 22C, a column 22E, and a beam 23B connecting the columns 22C and 22E. That is, the frame 20C is on the short side on the first positive direction X1 side of the base 21 and is located on the second negative direction Y2 side when viewed from the center of the base 21. Also, when the framework 20 is viewed in the first negative direction X2, the outer shape of the frame 20C is a rectangular shape that is long in the direction along the third axis Z. The dimension of the frame 20C in the direction along the second axis Y is the distance between the columns 22C and 22F. The dimension of the frame 20C in the direction along the third axis Z is the distance between the base 21 and the beam 23B.

[0019] As shown in FIG. 3, the frame 20D is composed of a base 21, columns 22D and 22F, and a beam 23B connecting the columns 22D and 22F. That is, the frame 20D is on the short side on the first negative direction X2 side and is located on the second negative direction Y2 side when viewed from the center of the base 21. Also, when the framework 20 is viewed facing the first positive direction X1, the outer shape of the frame 20D is a rectangular shape that is long in the direction along the third axis Z. The dimension of the frame 20D in the direction along the second axis Y is the distance between the columns 22D and 22F. The dimension of the frame 20D in the direction along the third axis Z is the distance between the base 21 and the beam 23B.

[0020] As described above, the frames 20A to 20D all have the same rectangular outer shape. Also, the long sides and short sides of the outer shapes of the frames 20A to 20D all have the same dimensions. That is, the frames 20A to 20D all have the same outer shape and dimensions.

[0021] As shown in FIG. 1, the prefabricated Japanese-style room includes a plurality of tatami mats 30. The tatami mats 30 are laid on the surface facing the upward direction Z1 of the floorboards. In this embodiment, six tatami mats 30 are laid out on the base 21 without gaps.

[0022] <Regarding panels, etc.> As shown in FIG. 1, the prefabricated Japanese-style room 10 further includes a plurality of panels 40, a rear wall 50, and a front panel 60. All of these are for partitioning the indoor space by covering the framework 20.

[0023] Multiple panels 40 are attached to the frame 20 by being fitted into frames 20A to 20D of the frame 20. Multiple panels 40 consist of two first side panels 40A and two second side panels 40B. In this embodiment, each panel 40 is a crawl-through panel 41, a serving opening panel 42, a wall panel with a window 43, and a wall panel without a window 44. The two first side panels 40A are the wall panel with a window 43 and the wall panel without a window 44. The two second side panels 40B are the crawl-through panel 41 and the serving opening panel 42. The crawl-through panel 41 is detachable from the frame 20 and is positioned next to the wall panel with a window 43 when attached to the frame 20. The supply opening panel 42 is detachable from the frame 20 and, when attached to the frame 20, is positioned alongside the windowless wall panel 44.

[0024] As shown in Figure 2, the entrance door panel 41 is a plate-shaped panel. When the entrance door panel 41 is viewed in a direction parallel to the plate thickness, its outer shape is rectangular. The dimension of the shorter side of the entrance door panel 41 is approximately the same as the dimension of the shorter side of the frame 20A. Also, the dimension of the longer side of the entrance door panel 41 is approximately the same as the dimension of the longer side of the frame 20A. The entrance door panel 41 is attached to the framework 20 by being fitted into the frame 20A.

[0025] The crawl-through entrance panel 41 has a crawl-through entrance 41A and a sliding door 41B. The crawl-through entrance 41A is an entrance to the prefabricated Japanese-style room 10. The dimension of the crawl-through entrance 41A in the direction along the second axis Y is less than half the dimension of the crawl-through entrance panel 41 in the direction along the second axis Y. When viewing the crawl-through entrance panel 41 facing the first negative direction X2, the crawl-through entrance 41A is located below the center of the crawl-through entrance panel 41 in the direction Z2. The sliding door 41B is a rectangular shape with substantially the same shape and dimensions as the crawl-through entrance 41A. The sliding door 41B is slidable in the direction along the second axis Y. That is, the crawl-through entrance 41A can be opened and closed by sliding the sliding door 41B.

[0026] As shown in Figure 3, the supply opening panel 42 is a plate-shaped panel. When the supply opening panel 42 is viewed in a direction parallel to the plate thickness, its outer shape is rectangular. The dimension of the shorter side of the supply opening panel 42's outer shape is the same as the dimension of the shorter side of the crawl-through opening panel 41's outer shape. Also, the dimension of the longer side of the supply opening panel 42's outer shape is the same as the dimension of the longer side of the crawl-through opening panel 41's outer shape. The supply opening panel 42 is attached to the framework 20 by being fitted into the frame 20B.

[0027] The serving opening panel 42 has a serving opening 42A and a sliding door 42B. The serving opening 42A is an entrance to the prefabricated Japanese-style room 10. The dimension of the serving opening 42A in the direction along the second axis Y is larger than the dimension of the opening of the crawl-through entrance 41A in the direction along the second axis Y. In other words, the serving opening 42A is a larger entrance than the crawl-through entrance 41A. The sliding door 42B is a rectangular shape with approximately the same shape and dimensions as the serving opening 42A. The sliding door 42B is slidable in the direction along the second axis Y. That is, the serving opening 42A can be opened and closed by sliding the sliding door 42B.

[0028] As shown in Figure 2, the windowed wall panel 43 is a plate-shaped panel. When viewed in a direction parallel to the plate thickness, the outer shape of the windowed wall panel 43 is rectangular. The dimension of the shorter side of the outer shape of the windowed wall panel 43 is the same as the dimension of the shorter side of the outer shape of the entrance panel 41. Also, the dimension of the longer side of the outer shape of the windowed wall panel 43 is the same as the dimension of the longer side of the outer shape of the entrance panel 41. The windowed wall panel 43 is adjacent to the back wall 50, with the column 22C to which the back wall 50 is connected in between. In this case, the column 22C is a specific column. The windowed wall panel 43 is fitted into a frame 20C that includes the column 22C. When fitted into the frame 20C, the windowed wall panel 43, together with the back wall 50 and the front panel 60, partitions the interior space.

[0029] The windowed wall panel 43 has a window 43A. The window 43A consists of an opening that penetrates the windowed wall panel 43 and a shoji screen that closes the opening. The window 43A can bring light from the outside into the interior of the prefabricated Japanese-style room 10.

[0030] As shown in Figure 3, the windowless wall panel 44 is a plate-shaped panel. When the windowless wall panel 44 is viewed in a direction parallel to its thickness, its outer shape is rectangular. The dimension of the shorter side of the windowless wall panel 44's outer shape is the same as the dimension of the shorter side of the entrance panel 41's outer shape. Also, the dimension of the longer side of the windowless wall panel 44's outer shape is the same as the dimension of the longer side of the entrance panel 41's outer shape. The windowless wall panel 44 is adjacent to the back wall 50, with the column 22D to which the back wall 50 is connected in between. In this case, the column 22C is a specific column. The windowless wall panel 44 is fitted into a frame 20D that includes the column 22D. When fitted into the frame 20D, the windowless wall panel 44, together with the back wall 50 and the front panel 60, partitions the interior space.

[0031] The windowless wall panel 44 does not have windows or doorways that penetrate in a direction parallel to the thickness of the panel. Therefore, the windowless wall panel 44 cannot bring light from the outside to the inside of the prefabricated Japanese-style room 10, unlike the windowed wall panel 43.

[0032] Thus, all of the panels 40 have the same rectangular shape. Furthermore, the long and short sides of the external shape of all of the panels 40 are the same dimensions. Therefore, all of the panels 40 have the same external shape and dimensions. On the other hand, all of the panels 40 differ in appearance from one another in terms of the presence or absence of an opening that penetrates in the thickness direction of the panel, and the dimensions of the opening. Specifically, the only panel 40 that has a crawl-through opening 41A is the crawl-through opening panel 41. The only panel 40 that has a serving opening 42A is the serving opening panel 42. The only panel 40 that has a window 43A is the wall panel with a window 43. The only panel 40 that does not have an opening is the wall panel without a window 44.

[0033] As shown in Figure 1, the rear wall 50 is connected to the side of the frame 20 facing the second negative direction Y2. The rear wall 50 includes a floor kit 51 and a fixed wall 52. The alcove kit 51 is connected to the first positive direction X1 side when viewed from the center of the frame 20 in the direction along the first axis X, among the surfaces facing the second negative direction Y2. The alcove kit 51 has a stepped floor that rises upward Z1 when viewed from the tatami mat 30. In addition, when the alcove kit 51 is viewed facing downward Z2, it has a wall that protrudes in the second negative direction Y2. The floor and wall demarcate the space located upward Z1 when viewed from the floor, i.e., the alcove. Therefore, the alcove kit 51 forms an alcove in the prefabricated Japanese-style room 10.

[0034] The fixed wall 52 is connected to the first negative direction X2 side of the frame 20, when viewed from the center in the direction along the first axis X, on the side facing the second negative direction Y2. The fixed wall 52 is connected to the frame 20 and the alcove kit 51. The fixed wall 52 and the alcove kit 51 completely block the entire surface of the frame 20 facing the second negative direction Y2.

[0035] The front panel 60 is detachable from the frame 20 and is positioned opposite the rear wall 50 across the interior space. The front panel 60 has a plurality of sliding doors 61. The plurality of sliding doors 61 are arranged to cover the surface of the frame 20 facing the second positive direction Y1. In this embodiment, there are four sliding doors 61. The four sliding doors 61 are fitted between the long side of the base 21 on the second positive direction Y1 side and the beam 23A on the second positive direction Y1 side. Each sliding door 61 is slidable in the direction along the first axis X. When viewing each sliding door 61 facing the second negative direction Y2, if the four sliding doors 61 are arranged so that they do not overlap each other, the entire surface of the frame 20 facing the second positive direction Y1 is covered. Then, by sliding the four sliding doors 61, a portion of the surface of the frame 20 facing the second positive direction Y1 is opened.

[0036] The prefabricated Japanese-style room 10 further includes a first canopy 81 and a second canopy 82. The first canopy 81 is, as a whole, a long, plate-like structure in the direction along the first axis X. The first canopy 81 is fixed to the girder 23A on the second positive direction Y1 side. The first canopy 81 is inclined so that it is positioned lower towards the Z2 direction as it approaches the second positive direction Y1.

[0037] The second canopy 82 is, as a whole, a long, plate-like structure in the direction along the second axis Y. The second canopy 82 is fixed to the beam 23B on the first positive direction X1 side. The second canopy 82 is inclined so that the closer it is to the first positive direction X1, the lower it is located towards the Z2 direction.

[0038] <Regarding connecting members> As shown in Figures 2 and 3, the prefabricated Japanese-style room 10 is equipped with multiple first connecting members 70. In this embodiment, three first connecting members 70 are connected to one first side panel 40A.

[0039] As shown in Figure 4, the first connecting member 70 connects the first side panel 40A to a specific column. The first connecting member 70 can also rotate the first side panel 40A around an axis extending parallel to the column 22 until it is parallel to the back wall 50. The first connecting member 70 is a hinge. Therefore, the first connecting member 70 has a rotation axis and two fixing plates.

[0040] With the first side panel 40A fitted into the frame 20A, the rotation axis of the first connecting member 70 is exposed to the outside. On the other hand, with the first side panel 40A fitted into the frame 20A, the two fixing plates of the first connecting member 70 are fixed to the column 22D or the first side panel 40A, respectively, so that the two fixing plates of the first connecting member 70 are not exposed to the outside.

[0041] As shown in Figures 2 and 3, the prefabricated Japanese-style room 10 is equipped with multiple second connecting members 80. In this embodiment, one second connecting member 80 connects one pair of first side panels 40A and second side panels 40B.

[0042] As shown in Figure 4, the second connecting member 80 connects the first side panel 40A and the second side panel 40B. The second connecting member 80 can rotate the second side panel 40B until it overlaps with the first side panel 40A, using an axis extending parallel to the column 22 as the axis of rotation.

[0043] The second connecting member 80 has a plurality of hinges and a connecting plate. Some of the plurality of hinges connect the first side panel 40A to the connecting plate. The remaining hinges connect the second side panel 40B to the connecting plate. When the hinges move to fold, the first side panel 40A and the second side panel 40B rotate to overlap. In other words, the second connecting member 80 has two axes of rotation. When the first side panel 40A and the second side panel 40B are fitted into the frame 20A to 20D, the column 22 located between the first side panel 40A and the second side panel 40B prevents the hinges from moving to fold.

[0044] As shown in Figures 5 and 6, each panel 40 is equipped with a stopper 45. The stopper 45 is cylindrical and extends parallel to the column 22. The length of the stopper 45 is longer than the dimension in the direction along the third axis Z of the base 21. The stopper 45 is housed in a recessed hole in the bottom surface of the panel 40. The hole is recessed deeper than the length of the stopper 45. When the panel 40 is fitted into the frame 20A to 20D, the stopper 45 is housed inside the panel 40. When the panel 40 is detached from the frame 20A to 20D by the first connecting member 70, the stopper 45 protrudes from the bottom surface.

[0045] <Operation of this embodiment> As shown in Figure 5, when the first side panel 40A and the second side panel 40B are rotated by the first connecting member 70 so that they are detached from the frame 20A to 20D, it is possible to create a space that resembles a stage on the tatami mat 30. In this case, in addition to the back wall 50, multiple panels 40 can be arranged to serve as a background.

[0046] Furthermore, as shown in Figure 6, by rotating the second side panel 40B so that it overlaps with the first side panel 40A using the second connecting member 80, the background area can be made smaller compared to before the rotation using the second connecting member 80. In addition, the appearance of the background panel 40 can be changed.

[0047] <Effects of this embodiment> (1) The first connecting member 70 connects the first side panel 40A to a specific column, which is either column 22C or column 22D, and allows the first side panel 40A to rotate using an axis extending parallel to the specific column as the axis of rotation until it is parallel to the back wall 50.

[0048] With the above configuration, when it is desired to create a space that resembles a stage within the interior, the first side panel 40A can be rotated and moved by the first connecting member 70 without having to remove the first side panel 40A from the frame 20. Therefore, the modular Japanese-style room 10 can avoid the hassle of removing the first side panel 40A from the frame 20 when it is desired to create a space that resembles a stage within the interior.

[0049] (2) According to the above configuration, the second connecting member 80 connects the first side panel 40A and the second side panel 40B. Therefore, when the first side panel 40A is rotated by the first connecting member 70, the second side panel 40B can also be moved together with it, detached from the frame 20A or frame 20B. Thus, the modular Japanese-style room 10 can avoid the extra step of having to detach the second side panel 40B from the frame 20 separately from the first side panel 40A when moving it.

[0050] (3) The second connecting member 80 can rotate the second side panel 40B around an axis extending parallel to the column 22 until it overlaps with the first side panel 40A. With the above configuration, when it is desired to create a space that resembles a stage within the interior, it may not be possible to extend the second side panel 40B to the extension of the first side panel 40A. Even in such cases, the modular Japanese-style room 10 can be moved to a position where a space resembling a stage within the interior can be created by overlapping the second side panel 40B with the first side panel 40A.

[0051] For example, a user can use the modular Japanese-style room 10 with the second side panel 40B rotated until it overlaps with the first side panel 40A. Alternatively, for example, when viewing the modular Japanese-style room 10 in a direction along the third axis Z, the user can use it with the second side panel 40B rotated until the angle between the second side panel 40B and the first side panel 40A is 90 degrees.

[0052] (4) The panel 40 has a stopper 45. The stopper 45 protrudes from the bottom surface of the panel 40 after being rotated from the position where the first connecting member 70 partitions the interior space. With the above configuration, it is easier to fix the panel 40 when the panel 40 is removed from the frames 20A to 20D.

[0053] (5) The stopper 45 is stored inside the panel 40 when the panel 40 is fitted into the frame 20A to 20D. With the above configuration, when the panel 40 is fitted into the frame 20A to 20D, it is possible to prevent the stopper 45 from protruding and spoiling the appearance of the Japanese-style room space.

[0054] <Example of changes> The above embodiment can be implemented with the following modifications. The above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0055] The shape of the frame 20 is not limited to the above embodiment. For example, when viewing the frame 20 facing downwards Z2, it may be hexagonal or polygonal. It is sufficient that it has at least a rear wall 50, a front panel 60, a first side panel 40A, and attachable bases 21 and columns 22.

[0056] The frame 20 does not necessarily have to have all of the frames 20A to 20D. For example, the frame 20 may have only frames 20C and 20D. In this case, the panel 40 becomes detachable from frames 20C and 20D.

[0057] The frame 20 does not necessarily have to have horizontal members 23. In this case, for example, the frame 20A may be composed of a base 21, columns 22A and 22E. In this case, the frame 20A is not closed in the upward direction Z1. In other words, the frame 20A does not have to be a closed frame, and it is sufficient that it encloses at least three directions and allows the panel 40 to be fitted into it.

[0058] • Not all of the multiple panels 40 have to be different in appearance other than their external shape and dimensions. For example, of the four panels 40, one may be a wall panel 43 with a window, and the remaining three may be wall panels 44 without windows.

[0059] Multiple panels 40 may consist only of first side panels 40A. In other words, the prefabricated tea room 10 does not need to have a second side panel 40B. Also, the prefabricated Japanese-style room 40 may have only one first side panel 40A.

[0060] The rear wall 50 is not limited to the example where it is composed of the alcove kit 51 and the fixed wall 52. For example, the rear wall 50 may be composed of a single plate-like wall. The front panel 60 is not limited to examples where it is composed of multiple sliding doors 61. For example, the front panel 60 only needs to be detachable from the frame 20 and does not need to be a sliding type.

[0061] The second connecting member 80 does not need to be able to rotate the second side panel 40B until it overlaps with the first side panel 40A. The second connecting member 80 may simply connect the first side panel 40A and the second side panel 40B. Furthermore, the prefabricated Japanese-style room 10 does not need to be equipped with the second connecting member 80.

[0062] The stopper 45 does not have to be stored inside the panel 40 when the panel 40 is fitted into the frame 20A to 20D. For example, the stopper 45 may be attached to the outside of the panel 40. Also, the panel 40 does not have to be equipped with a stopper 45.

[0063] The first connecting member 70 only needs to be capable of rotating the first side panel 40A until it is parallel to the rear wall 50. Therefore, the detailed structure of the first connecting member 70 is not limited to the example of the above embodiment. For example, the fixing plate of the first connecting member 70 may be fixed to the column 22D or the first side panel 40A such that the rotation axis of the first connecting member 70 and the fixing plate of the first connecting member 70 are exposed to the outside when the first side panel 40A is fitted into the frame 20A.
