Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when a mobile unit is used for living or accommodation purposes, the installation of a bed is assumed. However, since the bed takes up space, there is a problem that the living space becomes narrower accordingly. Further, such a problem can occur not only in mobile units but also in rooms with limited space.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to make it difficult for the living space to become narrow even when a bed is installed in a room.

Means for Solving the Problems

[0006] The invention according to claim 1 is a room structure, for example, as shown in FIGS. 1 to 7, a pair of parallel side walls 14, 15 provided on two sides of the room, and Bed support parts 25 respectively fixed to the inner wall surfaces of the pair of the side walls 14 and 15, and a bed 26 spanned and supported by the pair of the bed support parts 25, wherein the bed 26 includes a plurality of bed plates 27 and 28 arranged adjacent to each other in a direction orthogonal to the direction in which the bed 26 is spanned by the pair of the bed support parts 25 in a plan view.

[0007] According to the invention described in claim 1, since the bed 26 includes a plurality of bed plates 27 and 28 arranged adjacent to each other in a direction orthogonal to the direction in which the bed 26 is spanned by the pair of the bed support parts 25 in a plan view, by stacking the plurality of bed plates 27 and 28 or removing the plurality of bed plates 27 and 28 from the pair of the bed support parts 25, the dimensions occupied by the bed 26 in the room can be suppressed, so that even if the bed 26 is installed in the room, the living space is not likely to become narrow.

[0008] The invention described in claim 2 is, for example, as shown in FIGS. 1 to 7, in the room structure described in claim 1, including the pair of the side walls 14 and 15 and another side wall 13 positioned between the pair of the side walls 14 and 15, the three side walls 13, 14, and 15 provided on three sides of the room and adjacent to each other in a U shape in a plan view, including the pair of the bed support parts 25 and another bed support part 25 positioned between the pair of the bed support parts 25, and having the three bed support parts 25 respectively fixed to the inner wall surfaces of the three side walls 13, 14, and 15, wherein, among the plurality of the bed plates 27 and 28, one bed plate 27 is spanned by the three bed support parts 25, and the other bed plate 28 is spanned by the pair of the bed support parts 25.

[0009] According to the invention described in claim 2, among the plurality of bed plates 27, 28, one bed plate 27 is spanned across the three-sided bed support portion 25, and the other bed plate 28 is spanned across the pair of bed support portions 25. Therefore, it is possible to remove the other bed plate 28 from the pair of bed support portions 25 or remove one bed plate 27 from the three-sided bed support portion 25. As a result, by stacking the other bed plate 28 on top of one bed plate 27 or removing both of the plurality of bed plates 27, 28 from the three-sided bed support portion 25, the dimension by which the bed 26 protrudes toward the center of the room can be suppressed. Thus, even when the bed 26 is installed in the room, the living space is not likely to become narrow.

[0010] The invention described in claim 3 is, for example, as shown in FIG. 7 and the like, in the room structure described in claim 1, The bed 26 further includes connecting means (concave groove portion 27a, convex strip portion 28a) for detachably connecting the other end portion of one of the adjacent bed plates 27 among the plurality of bed plates 27, 28 and one end portion of the other adjacent bed plate 28.

[0011] According to the invention described in claim 3, the bed 26 further includes connecting means for detachably connecting the other end portion of one of the adjacent bed plates 27 among the plurality of bed plates 27, 28 and one end portion of the other adjacent bed plate 28. Therefore, when connecting the plurality of bed plates 27, 28 to be used as the bed 26, the integrity of the plurality of bed plates 27, 28 is increased, and the plurality of bed plates 27, 28 can be stably used without being bent separately. Furthermore, since the plurality of bed plates 27, 28 can be easily detached and attached, when it is desired to expand the living space of the room or at bedtime, the work of detaching and connecting the plurality of bed plates 27, 28 does not take much time. As a result, the living space of the room can be expanded immediately, or the bed 26 can be used immediately.

[0012] The invention described in claim 4 is, for example, as shown in FIGS. 4, 6, and 7, in the room structure described in claim 1, On the upper surfaces of the pair of the bed support parts 25, convex parts 25c are respectively provided. Among the plurality of the bed plates 27, 28, insertion holes 28d into which the convex parts 25c are inserted are formed on the lower surfaces of both end parts in the spanning direction of at least one of the bed plates 28.

[0013] According to the invention described in claim 4, among the plurality of the bed plates 27, 28, the insertion holes 28d into which the convex parts 25c respectively provided on the upper surfaces of the pair of the bed support parts 25 are inserted are formed on the lower surfaces of both end parts in the spanning direction of at least one of the bed plates 28. Therefore, when at least one of the bed plates 28 is spanned over the pair of the bed support parts 25, the convex parts 25c are inserted into the insertion holes 28d, and it becomes difficult for at least one of the bed plates 28 to be displaced. When it is desired to expand the living space of the room, at least one of the bed plates 28 may be removed so that the convex parts 25c come out of the insertion holes 28d, and the living space of the room can be expanded immediately.

[0014] The invention described in claim 5 is, for example, as shown in FIGS. 2, 5, and 6, in the room structure described in claim 1. The bed support part 25 is characterized by having a frame body 25a fixed to the inner wall surfaces of the side walls 14, 15 and a perforated board 25b attached to the surface of the frame body 25a.

[0015] According to the invention described in claim 5, since the bed support part 25 has the frame body 25a fixed to the inner wall surfaces of the side walls 14, 15 and the perforated board 25b attached to the surface of the frame body 25a, any article that can be hooked on the holes of the perforated board 25b can be hooked on the perforated board 25b and stored. Thereby, the bed support part 25 has both the function of supporting the bed 26 and the function of storing articles, so the convenience is high. If articles can be stored in this way, it becomes difficult for the living space to become narrow.

[0016] The invention described in claim 6 is, for example, as shown in FIGS. 1, 5, and 6, in the room structure described in claim 1. It further includes a plurality of movable benches 21 provided on the floor 10 of the room and having casters 22a provided on the bottom surface. The plurality of movable benches 21 are characterized in that they are gathered below the bed 26 to form a lower bed.

[0017] According to the invention described in claim 6, since the plurality of movable benches 21 are gathered below the bed 26 to form a lower bed, together with the bed 26, it can be used as a double-decker bed. Furthermore, since the plurality of movable benches 21 can be freely moved on the floor 10 to form various configurations, they can be used for purposes other than the lower bed, providing high convenience.

[0018] According to the invention described in claim 7, as shown in FIGS. 1 to 6 for example, the room structure according to any one of claims 1 to 6 is characterized in that it is placed on a trolley 2 and transported by an automobile, and is the internal space of a mobile unit 1 formed in a box shape.

[0019] According to the invention described in claim 7, since the room structure is placed on a trolley 2 and transported by an automobile, and is the internal space of a mobile unit 1 formed in a box shape, by adopting a bed 26 having a plurality of bed boards 27, 28, even in the mobile unit 1 having only a limited room space, the living space is less likely to become narrow. That is, by stacking the plurality of bed boards 27, 28 or removing the plurality of bed boards 27, 28 from a pair of bed support portions 25, the dimension of the bed 26 occupying the internal space of the mobile unit 1 can be suppressed, so that even if the bed 26 is installed in the internal space of the mobile unit 1, the living space is less likely to become narrow.

Effect of the Invention

[0020] According to the present invention, even if a bed is installed in the room, the living space can be made less likely to become narrow.

Embodiments for Carrying Out the Invention

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, although various technically preferable limitations are imposed on the embodiments described below for carrying out the present invention, the technical scope of the present invention is not limited to the following embodiments and illustrated examples. Note that the directions in the following embodiments and illustrated examples are merely set for convenience of explanation.

[0023] 〔Regarding the outline of the mobile unit〕 In FIG. 1, reference numeral 1 indicates a mobile unit. The mobile unit 1 in the present embodiment is a trailer house, which is placed on a trolley 2 and towed and transported by an automobile (not shown), and can be placed at a stationary location while being placed on the trolley 2. Note that the mobile unit 1 in the present embodiment is a trailer house, but it is not limited thereto, and it may be a container house that is unloaded from the trolley 2 and used. In that case, the mobile unit 1 is installed on a foundation.

[0024] In addition, the mobile unit 1 obtains a vehicle inspection and is set within the size limits of regulations (Building Standards Law, Road Transportation Vehicle Law) (Safety Standard Article 2 limit values: vehicle width within 2.5 m, vehicle length within 12 m, vehicle height within 3.8 m). As a result, the mobile unit 1 can legally move on public roads. However, in some cases, with special permission, it may be set to a size larger than the limit values. Furthermore, the mobile unit 1 shall satisfy all the criteria required for being placed at a stationary location.

[0025] The carriage 2, also called a chassis, includes a support base 3 to which wheels 3a are attached, and a plurality of support legs 4 detachably provided on the support base 3. The support base 3 has the box-shaped unit body of the mobile unit 1 placed thereon and integrated. Also, at the front end of this support base 3, a connecting portion (not shown) that protrudes forward and is connected to an automobile is integrally formed. The plurality of support legs 4 are provided at a total of six locations, namely, at the four corners of the support base 3 and at two locations near the wheels 3a (the center in the length direction of the support base 3). The support leg 4 is a jack device capable of manually raising and lowering the portion in contact with the support base 3.

[0026] 〔Regarding the configuration of the mobile unit〕 Next, the configuration of the mobile unit 1 will be described in detail. The mobile unit 1 of this embodiment, which is a trailer house, is configured to include the carriage 2. Hereinafter, the box-shaped unit body placed on the support base 3 of the carriage 2 will be described.

[0027] As shown in FIGS. 1 to 6, the unit body includes, as an outer shell, a floor 10 placed on the support base 3 and integrated therewith, a roof 11, and four side walls 12 to 15 provided between the floor 10 and the roof 11, and is formed in a box shape. The unit body is long in one direction (front-rear direction) and short in the other direction (left-right direction), and is formed in a rectangular parallelepiped shape. Since the mobile unit 1 of this embodiment is used for the purpose of residence or accommodation, the internal space surrounded by these floor 10, roof 11, and four side walls 12 - 15 is treated as a living space (room).

[0028] The floor 10, roof 11, and four side walls 12 - 15 are composed of architectural wooden panels used in the so-called panel method. The panel method refers to a construction method in which building components such as walls, floors, and roofs are pre-panelized in a factory and these panels are assembled and constructed at the construction site. The architectural wooden panel has a structure with a face material attached to both sides or one side of a frame body in which vertical and horizontal framing members are assembled in a rectangular shape and is internally hollow, and the internally hollow part is filled with a fiber-based or foam-based heat insulating material. In this embodiment, architectural wooden panels are used as the floor 10, roof 11, and four side walls 12 - 15 that constitute the outer shell of the mobile unit 1, and the mobile unit 1 is formed by the panel method. However, it is not limited to this, and the mobile unit 1 may be formed based on other construction methods of buildings such as the framework method, the wall method, and the two-by-four method.

[0029] The floor 10 is long in one direction (front - rear direction) and short in the other direction (left - right direction), and is rectangular in plan view. And by appropriately providing a floor finishing material (for example, a flooring material) on the upper surface, the floor surface in the space within the mobile unit 1 is constituted. Such a floor 10 is composed of a plurality of architectural wooden panels. Also, the four side walls 12 - 15 are erected and fixed at the outer peripheral edge of the floor 10.

[0030] The roof 11 is formed long in one direction (front-rear direction) and short in the other direction (left-right direction), resulting in a rectangular shape in plan view. And by appropriately providing a ceiling material (for example, a decorative ceiling board material) on the lower surface, the ceiling surface in the space within the mobile unit 1 is configured. Furthermore, it is a single-slope roof where one side (left side) in the short side direction is high and the opposite side (right side) is low. This enables the induction of rainwater to one side. Also, as will be described later, since an entrance / exit 14a is provided on the left side of the unit body, it is possible to prevent rainwater from flowing into the entrance / exit 14a. Note that since the roof 11 is inclined in a single-slope manner like this, the ceiling of this embodiment is also a sloping ceiling that slopes to one side, but it is not limited to this, and a horizontal ceiling composed of eaves and ceiling materials or the like may be formed.

[0031] Such a roof 11 is composed of a plurality of building wooden panels. Also, a roofing material (for example, a galvanized steel sheet (registered trademark)) is provided on the surface of the roof 11. Furthermore, the roof 11 is placed and fixed on the upper ends of the four side walls 12 to 15, and projects slightly outside the outdoor side surfaces of the four side walls 12 to 15.

[0032] The four side walls have a first side wall 12, a second side wall 13, a third side wall 14, and a fourth side wall 15. The first side wall 12 is provided at one end side (front end side) in the length direction of the floor 10. The second side wall 13 is provided at the other end side (rear end side) in the length direction of the floor 10. The third side wall 14 is provided between one end in the width direction (left end) of the first side wall 12 and one end in the width direction (left end) of the second side wall 13. The fourth side wall 15 is provided between the other end in the width direction (right end) of the first side wall 12 and the other end in the width direction (right end) of the second side wall 13. The first side wall 12 and the second side wall 13 respectively form the front surface and the rear surface of the unit body, and have a short width dimension (dimension in the left-right direction). The third side wall 14 and the fourth side wall 15 respectively form the left side surface and the right side surface of the unit body, and have a long width dimension (dimension in the front-rear direction). Such four-sided side walls 12 to 15 are each composed of a plurality of building wooden panels. Further, an exterior material (such as a galvanized steel sheet or a siding material) is provided on the surfaces of the four-sided side walls 12 to 15, and an interior material (such as a gypsum board) is provided on the indoor side, and a wall finishing material (such as a cloth) is applied.

[0033] On the third side wall 14, there is formed an entrance 14a with fittings, the height of the lower end portion of which is substantially equal to that of the floor 10 and the height of the upper end portion reaches near the roof 11. Further, on the third side wall 14, a fixed window 14b set at the same height as the entrance 14a is provided side by side with the entrance 14a. The fittings of the entrance 14a and the fixed window 14b are both glass fittings and glass windows (glass walls).

[0034] On the fourth side wall 15, as a waist-high window whose lower end portion is located above the floor 10, an opening / closing window 15a configured to be openable and closable and a fixed window 15b that cannot be opened or closed are provided side by side. The opening / closing window 15a and the fixed window 15b are both glass windows.

[0035] 〔Regarding the internal space of the mobile unit〕 The rear part of the internal space in the mobile unit 1 is a living space 20 treated as a living room. More specifically, it is treated as a living room and a bedroom combined. Therefore, the living space 20 is provided with living room facilities and bed facilities that have both the function of furniture for the living room and the function of furniture for the bedroom.

[0036] Note that the ceiling height of the lower part of such a living space 20 in the mobile unit 1 is set to be around 2300 mm, and the ceiling height of the higher part is set to be about 2500 mm. Also, the length of the living space 20 (the length from the inner wall surface of the second side wall 13 to the vicinity of the fixed windows 14b and 15b) is set to be around 2100 mm. Furthermore, the width of the living space 20 (the length from the inner wall surface of the third side wall 14 to the inner wall surface of the fourth side wall 15) is set to about 1900 to 2000 mm.

[0037] The living room facilities are provided on the floor 10 and have a plurality of movable benches 21 that can be moved by casters 22a. When the living space 20 is used as a living room, the movable bench 21 is treated as a bench, and when the living space 20 is used as a bedroom, the movable bench 21 is treated as a lower bed. In addition, the number of movable benches 21 is six in this embodiment, but it may be nine or other numbers.

[0038] The movable bench 21 includes a box-shaped storage portion 22 with a plurality of casters 22a attached to the lower surface and opening upward, and a lid portion 23 for closing the opening of the box-shaped storage portion 22. That is, when the lid portion 23 is removed, the opening can be opened and items can be stored in the box-shaped storage portion 22, and when the opening is closed by the lid portion 23, it can be used as a bench. The caster 22a includes a wheel and a locking portion for locking and unlocking the rotation of the wheel.

[0039] Such a movable bench 21 is formed in a square shape in plan view and has equal side lengths. And the length of one side is approximately the length obtained by dividing the short-side length of the internal space in the mobile unit 1 into three equal parts. Therefore, when three movable benches 21 are arranged side by side, they can be exactly fitted between the third side wall 14 and the fourth side wall 15. In this embodiment, since six movable benches 21 are used, the movable benches 21 in a row of three can be arranged in two rows. By arranging such two rows of movable benches 21 close to the second side wall 13 side as shown in FIG. 5, these plurality of movable benches 21 can be used as lower beds.

[0040] Incidentally, the length of one side of the movable bench 21 is set to about 640 mm, and the height dimension including the caster 22a is set to about 350 to 400 mm. Therefore, when six movable benches 21 are used as the lower bed as shown in FIG. 5, the size is about the same as that of a so-called semi-double bed.

[0041] Moreover, since the movable bench 21 is movable, a plurality of movable benches 21 can be freely combined and used. Therefore, for example, as shown in FIG. 6, by arranging them in a J shape in plan view, they can be used as if they were a sofa. In addition, they may be arranged in an L shape in plan view, or each one may be arranged at intervals so as to be scattered.

[0042] Incidentally, the plurality of movable benches 21 may include a movable bench-cum-table. This movable bench-cum-table has a lid portion 23 having a lid plate and a convex portion integrally provided on the lower surface of the lid plate and housed in a box-shaped storage portion. And when the convex portion of the movable bench-cum-table is housed in the box-shaped storage portion, it can be in the state of a bench with the upper surface of the lid plate as the seating surface, and when the lid portion is turned upside down and the lid plate is placed on the edge of the box-shaped storage portion, it can be in the state of a table with the upper surface of the convex portion as the top surface. When the movable bench-cum-table is in the state of a table, the height position of the upper surface is higher than that of the other movable benches 21, so it is easier to use as a table. Also, when it is in the state of a bench, it looks the same as the other movable benches 21 and can be used in the same way as the other movable benches 21.

[0043] The bed facility includes a second side wall 13, and bed support portions 25 provided at the same height position with respect to the three side walls 13, 14, and 15 of the third side wall 14 and the fourth side wall 15 provided orthogonally to both sides of the second side wall 13 and adjacent to each other in a U shape (J shape), and a bed 26 supported by the bed support portions 25.

[0044] The bed support portion 25 has a frame body 25a assembled in a rectangular shape with vertical and horizontal frame members, and a perforated board 25b that covers the side surface and the front end surface of the frame body 25a on the living space 20 side. The perforated board 25b is not provided on the upper and lower surfaces of the frame body 25a, and these upper and lower surfaces of the frame body 25a are not covered. That is, the upper and lower surfaces of the bed support portion 25 are in a state where the upper and lower surfaces of the frame body 25a are exposed. Further, the perforated board 25b is a surface material formed with a large number of punch holes penetrating in the thickness direction, and thin metal linear members such as wires and wires, or hook members can be hooked through the punch holes. Thereby, furniture or the like having a linear member as a hooking portion or a hook member can be hooked and held on the surface of the bed support portion 25. Since the upper surface of the frame body 25a is the surface in contact with the bed 26, the height position of the upper end edge of the perforated board 25b is preferably slightly lower than the height position of the upper surface of the frame body 25a so that the bed 26 does not contact the perforated board 25b.

[0045] Among the bed support portions 25 provided on the three side walls 13, 14, and 15, the bed support portion 25 on the third side wall 14 side has a width dimension of about half the length between the second side wall 13 and the blind window 14b. Specifically, it is set to a width dimension of about 850 to 900 mm and does not reach the blind window 14b. Further, the height dimension of this bed support portion 25 is set to about 700 mm, and the upper end surface is arranged at a height position of 1400 mm from the floor 10.

[0046] On the other hand, the bed support portion 25 on the fourth side wall 15 side has a width dimension corresponding to the length between the second side wall 13 and the blind window 15b. Therefore, the width dimension is set longer than that of the bed support portion 25 on the third side wall 14 side. Specifically, it is set to a width dimension of about 2100 mm and reaches the blind window 15b. Further, the height dimension of this bed support portion 25 is set to about 700 mm, and the upper end surface is arranged at a height position of 1400 mm from the floor 10.

[0047] The bed support portion 25 on the second side wall 13 side has a width dimension corresponding to the length between the third side wall 14 and the fourth side wall 15. Specifically, it is set to a width dimension of about 2000 to 2100 mm. Further, the height dimension of this bed support portion 25 is set to about 700 mm, and the upper end surface is arranged at a height position of 1400 mm from the floor 10.

[0048] On the upper surface of the front end portion of the bed support portion 25 on the third side wall 14 side, a convex portion 25c protruding upward is fixedly provided. On the upper surface of the front end portion of the bed support portion 25 on the fourth side wall 15 side, a similar convex portion 25c is also fixedly provided. The positions of the two convex portions 25c in the front-rear direction of the mobile unit 1 are the same.

[0049] The bed 26 is placed on the upper surfaces of the three adjacent bed support portions 25 in a U-shaped (J-shaped) manner and is provided so as to span these three bed support portions 25. Therefore, the bed 26 is recognized as an upper bed with respect to the lower bed composed of a plurality of movable benches 21. However, when the plurality of movable benches 21 are not used as the lower bed, it is simply recognized as the bed 26. Such a bed 26 includes a first bed plate 27 spanned over the three bed support portions 25 and a second bed plate 28 spanned over two parallel bed support portions 25 among the three bed support portions 25. In other words, the bed 26 is in a state of being divided into two in its short side direction (the front-rear direction of the mobile unit 1), and thus includes the first bed plate 27 and the second bed plate 28.

[0050] Further, the bed 26 includes a handrail 29 provided at a position avoiding a ladder hanging portion 31, which will be described later, in the front end portion of the second bed plate 28. The handrail 29 may be configured to be foldable in a direction overlapping the upper surface of the second bed plate 28.

[0051] And such a bed 26 can be used as the bed 26 by arranging the first bed plate 27 and the second bed plate 28 side by side horizontally with respect to each other. Further, the first bed plate 27 and the second bed plate 28 can be used as a shelf against a wall by being arranged close to the central second side wall 13 in a stacked state.

[0052] The first bed plate 27 is a plate body formed in a rectangular shape in plan view, and is placed and spanned on each of the bed support portions 25 fixed to the three side walls 13, 14, and 15. This first bed plate 27 is provided in contact with the second side wall 13. In the present embodiment, the first bed plate 27 is in a state of being merely placed on each of the three bed support portions 25, but it may be fixed after being placed on each of the three bed support portions 25.

[0053] The second bed plate 28 is a plate body formed in a rectangular shape in plan view, and is placed and spanned on the bed support portion 25 fixed to the third side wall 14 and the bed support portion 25 fixed to the fourth side wall 15 among the bed support portions 25 fixed to the three side walls 13, 14, and 15. Note that this second bed plate 28 is in a state of being merely placed on the two parallel bed support portions 25 and is not fixed to the bed support portion 25.

[0054] Note that the longitudinal dimensions of the first bed plate 27 and the second bed plate 28 are set to a width dimension of about 2000 to 2100 mm, and the lateral dimension is set to about 440 mm. Further, the thickness dimensions of the first bed plate 27 and the second bed plate 28 are set to 50 mm. Therefore, the lateral dimension of the bed 26 formed by arranging the first bed plate 27 and the second bed plate 28 side by side horizontally with respect to each other is set to about 880 mm. That is, the bed 26 has a size comparable to that of a so-called single bed.

[0055] As shown in FIGS. 1 to 3, 5, and 7, the first bed plate 27 and the second bed plate 28 are connected when they are arranged side by side horizontally with respect to each other and used as the bed 26. More specifically, a concave groove portion 27a is formed on the end face of the first bed plate 27 on the side of the second bed plate 28. The concave groove portion 27a is formed in a long shape along the length direction of the first bed plate 27, and both ends in the length direction of the concave groove portion 27a are open. Also, a convex rib portion 28a is provided on the end face of the second bed plate 28 on the side of the first bed plate 27. The convex rib portion 28a is composed of an aluminum angle bar, and is inserted into a concave groove portion formed on the end face of the second bed plate 28 on the side of the first bed plate 27, and is fixed by a fixing material such as a screw. The convex rib portion 28a is formed in a long shape along the length direction of the second bed plate 28. Then, by inserting the convex rib portion 28a of the second bed plate 28 into the concave groove portion 27a of the first bed plate 27, they will be integrally connected. In other words, the bed 26 is provided with a concave-convex fitting structure composed of the concave groove portion 27a and the convex rib portion 28a as a connecting means for removably connecting the end portion of the first bed plate 27 on the side of the second bed plate 28 and the end portion of the second bed plate 28 on the side of the first bed plate 27. However, the form of the connecting means is not limited to such a concave-convex fitting structure, and can be appropriately changed, for example, using a latch fitting as the connecting means or using a magnet as the connecting means.

[0056] A melamine decorative board is attached as a decorative board 27b to the end face of the first bed plate 27 on the side of the first bed plate 27 and the groove bottom surface of the concave groove portion 27a. Also, a felt surface material is attached as a vibration-proof material 27c to the opposite end face. That is, the vibration-proof material 27c is provided on the end face of the first bed plate 27 on the side of the second side wall 13, and will be interposed between the first bed plate 27 and the second side wall 13. Thereby, the surface of the second side wall 13 is protected.

[0057] Melamine decorative boards are attached as decorative boards 28b to the end face of the second bed plate 28 on the side of the second bed plate 28 and the opposite end face. Also, a felt surface material is attached to the protruding direction side end face of the rib portion 28a as a vibration damping material 27c. That is, the vibration damping material 28c contacts the groove bottom surface of the concave groove portion 27a in the first bed plate 27 and can protect the concave groove portion 27a. Further, when the second bed plate 28 is laminated on the first bed plate 27, the vibration damping material 28c contacts the second side wall 13 at the protruding direction side end face of the rib portion 28a, so the surface of the second side wall 13 is protected.

[0058] Also, insertion holes 28d are formed in the lower surfaces of both end portions in the length direction of the second bed plate 28. As shown in FIGS. 4 and 6, these insertion holes 28d are holes into which the convex portions 25c provided on the upper surfaces of the bed support portions 25 on the third side wall 14 side and the upper surfaces of the bed support portions 25 on the fourth side wall 15 side are inserted. When the bed 26 is in use, the convex portions 25c of the bed support portions 25 are inserted into the insertion holes 28d in the lower surface of the second bed plate 28, so that the displacement of the bed 26 can be prevented.

[0059] Since the bed 26 is at a high position, it is necessary to climb up and down using the ladder 30. The ladder 30 is installed by being hooked on a pair of ladder hanging portions 31 provided at the front end portion of the second bed plate 28 when in use. When not in use, it is stored by being hooked on a storage hanging portion 32 provided on the surface of the third side wall 14.

[0060] 〔Regarding the living style in the living room space〕 In the living room space 20 of the mobile unit 1 configured as described above, the occupant can move a plurality of movable benches 21 or change the shape of the bed 26 and live in a state suitable for their own style.

[0061] For example, FIG. 5 shows the style at bedtime when there are a plurality of occupants. The six movable benches 21 are gathered on the second side wall 13 side and can be used as a bed. Among the movable benches 21, the three movable benches 21 on the first side wall 12 side are in a state where the locks of the casters 22a are engaged.

[0062] Above the bed composed of a plurality of movable benches 21, a bed 26 in the bed facilities is provided. That is, the first bed plate 27 and the second bed plate 28 are arranged side by side horizontally with each other and can be used as the bed 26. Further, the ridge portion 28a of the second bed plate 28 is inserted into the concave groove portion 27a of the first bed plate 27, and the first bed plate 27 and the second bed plate 28 are integrally connected. Furthermore, the convex portions 25c provided on the upper surface of the bed support portion 25 on the third side wall 14 side and the convex portions 25c provided on the upper surface of the bed support portion 25 on the fourth side wall 15 side are inserted into the insertion holes 28d formed on the lower surfaces of both ends in the length direction of the second bed plate 28, and the installation state of the bed 26 is stable.

[0063] The style shown in FIG. 5 can be said to be a style in which the living space 20 is used as a bedroom with a bunk bed. In other words, by providing the upper bed 26, it becomes possible to form a bunk bed in the living space 20.

[0064] FIG. 6 is a style when the living space 20 is used as a living room. The six movable benches 21 are arranged in a substantially J shape in plan view, and several occupants can sit at once.

[0065] Also, the bed 26 is in a state where the second bed plate 28 is stacked on the first bed plate 27, and the overhanging dimension of the bed 26 from the second side wall 13 can be suppressed. Therefore, an occupant sitting on the movable bench 21 located below the first bed plate 27 is less likely to feel a sense of compression by the first bed plate 27 during sitting and is less likely to hit their head when standing up.

[0066] The living style in the living space 20 is not limited to the above examples and can be changed as appropriate. The number of movable benches 21 can also be changed as appropriate. A plurality of movable benches 21 can be gathered and used, or one or more movable benches 21 can be spaced apart from other movable benches 21 and used. The bed 26 can usually be used as a shelf by stacking the second bed plate 28 on the first bed plate 27, and the second bed plate 28 can be deployed as the bed 26 when there are guests or the like.

[0067] 〔Regarding the expansion of the room structure〕 Although the room structure of this embodiment is applied to the internal space of the mobile unit 1 transported by an automobile, it is not limited to this, and it may be applied to rooms of ordinary buildings such as detached houses and apartment houses. In addition, for example, it may be applied to sleeping cars or passenger cabins of ships. Also, although the bed 26 of this embodiment is supported by being bridged over the three bed support parts 25 adjacent to each other in a U-shape in plan view, both the first bed plate 27 and the second bed plate 28 may be supported by being bridged over the two parallel bed support parts 25. In that case, convex parts 25c for both the first bed plate 27 and the second bed plate 28 are provided on the upper surfaces of the two bed support parts 25 to suppress the displacement of both the first bed plate 27 and the second bed plate 28. And if a bed 26 supported by being bridged over the two parallel bed support parts 25 can be adopted, a plurality of beds 26 can be arranged side by side in the living space 20. Also, although the bed 26 of this embodiment is provided with the first bed plate 27 and the second bed plate 28, it may be provided with three or more bed plates.

[0068] 〔Regarding the effects〕 According to this embodiment, the following excellent effects are achieved. That is, the bed 26 includes a first bed plate 27 spanned across the three bed support portions 25, and a second bed plate 28 adjacent to the first bed plate 27 and spanned between two parallel bed support portions 25 among the three bed support portions 25. Therefore, the second bed plate 28 can be removed from the two bed support portions 25, or the first bed plate 27 can be removed from the three bed support portions 25. Thereby, by stacking the second bed plate 28 on the first bed plate 27 or removing both the first bed plate 27 and the second bed plate 28 from the three bed support portions 25, the dimension by which the bed 26 protrudes toward the center of the room can be suppressed, so that the living space of the room is less likely to become narrow.

[0069] Further, the bed 26 further includes a connecting means for detachably connecting the end of the first bed plate 27 on the second bed plate 28 side and the end of the second bed plate 28 on the first bed plate 27 side. Therefore, when the first bed plate 27 and the second bed plate 28 are connected and used as the bed 26, the integrity of the first bed plate 27 and the second bed plate 28 is increased, and they can be stably used without being bent separately. Furthermore, since the attachment and detachment of the first bed plate 27 and the second bed plate 28 can be easily performed, when it is desired to expand the living space of the room or at bedtime, the work of removing and connecting the first bed plate 27 and the second bed plate 28 does not take much time. Thereby, the living space of the room can be immediately expanded, or the bed 26 can be immediately used.

[0070] Also, insertion holes 28d into which convex portions 25c provided on the upper surfaces of the two bed support portions 25 are inserted are formed on the lower surfaces of both ends in the length direction of the second bed plate 28. Therefore, when the second bed plate 28 is spanned across the two bed support portions 25, the convex portions 25c are inserted into the insertion holes 28d, and the second bed plate 28 is less likely to be displaced. When it is desired to expand the living space of the room, the second bed plate 28 can be removed so that the convex portions 25c come out of the insertion holes 28d, and the living space of the room can be immediately expanded.

[0071] In addition, the bed support portion 25 has a frame body 25a fixed to the inner wall surfaces of the side walls 13, 14, and 15, and a perforated board 25b attached to the surface of the frame body 25a. Therefore, any article that can be hooked on the holes of the perforated board 25b can be hooked on the perforated board 25b and stored. As a result, the bed support portion 25 has both the function of supporting the bed 26 and the function of storing articles, which is highly convenient. If articles can be stored in this way, the living space is less likely to become narrow.

[0072] In addition, since the plurality of movable benches 21 are gathered towards the side wall 13 located in the middle of the three side walls 13, 14, and 15 to form a bed, they can be used as a two-tier bed together with the bed 26 supported by the three bed support portions 25. Furthermore, since the plurality of movable benches 21 can be freely moved on the floor 10 and used in various forms, they are highly convenient.

[0073] In addition, since the room structure is the internal space of the mobile unit 1 formed in a box shape and placed on the cart 2 and transported by an automobile, by adopting the bed 26 provided with the first bed plate 27 and the second bed plate 28, even in the mobile unit 1 having only a limited room space, the living space of the room is less likely to become narrow. That is, by stacking the second bed plate 28 on the first bed plate 27 or removing both the first bed plate 27 and the second bed plate 28 from the three bed support portions 25, the dimension by which the bed 26 protrudes toward the center of the room can be suppressed, so the living space of the room in the mobile unit 1 is less likely to become narrow.

[0074] In recent years, the realization of a decarbonized society through the promotion of carbon neutrality, which aims to substantially reduce carbon dioxide emissions to zero, and the achievement of the Sustainable Development Goals (SDGs) have been demanded. In the construction industry as well, efforts are underway to use wooden structures for buildings with low carbon dioxide emissions. Since the outer shell of the unit body of the mobile unit 1 of the present embodiment is composed of wooden building panels, it can contribute to the realization of a decarbonized society through the promotion of carbon neutrality and the achievement of the SDGs (such as Goal 7, Goal 12, and Goal 13).
