Description

[Technical Field]

[0001] The present invention relates to a room structure and a mobile unit. [Background technology]

[0002] Conventionally, mobile units that can be easily relocated or installed have been widely known as container houses, trailer houses, camper vans, etc. Demand for mobile units has been increasing in recent years, with some being permanently installed as residences, stores, or offices, others being used as temporary accommodations, and others being used as temporary housing in the event of natural disasters. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-305751 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when using a mobile unit for residential or lodging purposes, it is assumed that a bed will be installed, but the bed takes up space, which creates the problem of reducing the living space. This problem can occur not only with mobile units, but also in any room with limited space.

[0005] The present invention has been made in view of the above circumstances, and its object is to prevent the living space from becoming cramped even when a bed is installed in a room. [Means for solving the problem]

[0006] The invention described in claim 1 is a room structure, as shown in, for example, Figs. 1 to 7, A pair of parallel side walls 14, 15 provided on two sides of the room; a bed support portion 25 fixed to the inner wall surfaces of the pair of side walls 14, 15, and a bed 26 supported by the pair of bed support portions 25, The bed 26 is characterized by including a plurality of bed plates 27, 28 arranged adjacent to each other in a direction perpendicular to the direction in which the bed 26 is bridged across the pair of bed support portions 25 in a plan view.

[0007] According to the invention described in claim 1, the bed 26 is provided with a plurality of adjacent bed plates 27, 28 arranged in a direction perpendicular to the direction in which the bed 26 is spanned across a pair of bed support parts 25 in a plan view.Therefore, by stacking the plurality of bed plates 27, 28 or removing the plurality of bed plates 27, 28 from the pair of bed support parts 25, the amount of space that the bed 26 occupies in the room can be reduced, so that even if the bed 26 is installed in a room, the living space is less 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, The side walls 13, 14, 15 are provided on three sides of the room and are adjacent to each other in a U-shape in plan view, and include a pair of the side walls 14, 15 and another side wall 13 located between the pair of the side walls 14, 15; The bed support unit includes a pair of bed support parts 25 and another bed support part 25 located between the pair of bed support parts 25, and the bed support parts 25 on three sides are fixed to the inner wall surfaces of the side walls 13, 14, and 15 on three sides, respectively; Of the multiple bed plates 27, 28, one bed plate 27 is spanned across the bed support parts 25 on three sides, and the other bed plate 28 is spanned across a pair of the bed support parts 25.

[0009] According to the invention described in claim 2, one bed board 27 of the multiple bed boards 27, 28 is spanned across the bed support parts 25 on three sides, and the other bed boards 28 are spanned across a pair of bed support parts 25, so it is possible to remove the other bed board 28 from the pair of bed support parts 25, or to remove one bed board 27 from the bed support parts 25 on the three sides. As a result, by stacking the other bed board 28 on top of one bed board 27, or by removing both of the multiple bed boards 27, 28 from the bed support parts 25 on the three sides, the dimension of the bed 26 that protrudes towards the center of the room can be reduced, so even if 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, in the room structure described in claim 1, The bed 26 is characterized by further comprising connecting means (groove portion 27a, ridge portion 28a) for detachably connecting the other end of one adjacent bed plate 27 to one end of the other adjacent bed plate 28 among the plurality of bed plates 27, 28.

[0011] According to the invention described in claim 3, the bed 26 further includes a connecting means for detachably connecting the other end of one adjacent bed plate 27 of the plurality of bed plates 27, 28 to one end of the other adjacent bed plate 28. Therefore, when the plurality of bed plates 27, 28 are connected and used as the bed 26, the unity of the plurality of bed plates 27, 28 is increased, and the plurality of bed plates 27, 28 can be used stably without bending separately. Furthermore, since the multiple bed plates 27, 28 can be easily attached and detached, when you want to expand the living space of the room or when you go to sleep, there is no time-consuming task of removing and connecting the multiple bed plates 27, 28. This allows you to quickly expand the living space of the room or use the bed 26 immediately.

[0012] The invention described in claim 4 is, for example, as shown in Figures 4, 6 and 7, in the room structure described in claim 1, A pair of the bed support portions 25 are provided on the upper surfaces thereof with protrusions 25c, At least one of the bed plates 27, 28 has insertion holes 28d formed on the underside of both ends in the bridging direction, into which the protrusions 25c are inserted.

[0013] According to the invention described in claim 4, at least one bed plate 28 out of the plurality of bed plates 27, 28 has an insertion hole 28d formed on the underside of both ends in the spanning direction of the bed plate 28, into which the protrusions 25c provided on the upper surfaces of the pair of bed support parts 25 are inserted, so that when the at least one bed plate 28 is spanned across the pair of bed support parts 25, the protrusions 25c are inserted into the insertion hole 28d, making it difficult for the at least one bed plate 28 to shift position. When it is desired to expand the living space of the room, it is sufficient to remove at least one bed plate 28 so that the protrusions 25c can be removed from the insertion hole 28d, and the living space of the room can be immediately expanded.

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

[0015] According to the invention described in claim 5, the bed support part 25 has a frame body 25a fixed to the inner wall surface of the side walls 14, 15 and a perforated board 25b attached to the surface of the frame body 25a, so that any item that can be hung on the holes in the perforated board 25b can be hung on the perforated board 25b and stored. This makes the bed support part 25 highly convenient as it has both the function of supporting the bed 26 and the function of storing items, and being able to store items in this way prevents the living space from becoming narrow.

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

[0017] According to the invention described in claim 6, the plurality of movable benches 21 are gathered together below the bed 26 to form a lower bunk bed, and can be used as a bunk bed together with the bed 26. Furthermore, the plurality of movable benches 21 can be freely moved on the floor 10 to take on various forms, and can therefore be used as something other than a lower bunk bed, providing great convenience.

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

[0019] According to the invention of claim 7, since the room structure is the interior space of the box-shaped mobile unit 1 that is transported by automobile on the cart 2, by employing the bed 26 equipped with a plurality of bed plates 27, 28, the living space is less likely to become narrow even in a mobile unit 1 that has only a limited room space. That is, by stacking the plurality of bed plates 27, 28 or by removing the plurality of bed plates 27, 28 from the pair of bed support parts 25, the size that the bed 26 occupies in the interior space of the mobile unit 1 can be reduced, so that even if the bed 26 is installed in the interior space of the mobile unit 1, the living space is less likely to become narrow. [Effects of the Invention]

[0020] According to the present invention, even if a bed is installed in a room, the living space can be prevented from becoming narrow. [Brief explanation of the drawings]

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are subject to various limitations that are technically preferable for implementing the present invention, but 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 set solely for the convenience of explanation.

[0023] [Overview of the mobile unit] In Fig. 1, reference numeral 1 denotes a mobile unit. In this embodiment, the mobile unit 1 is a trailer house that is placed on a dolly 2 and towed and transported by an automobile (not shown), and is placed in a suitable location while still on the dolly 2. Although the mobile unit 1 in this embodiment is a trailer house, it is not limited to this and may be a container house that is used by being unloaded from the dolly 2. In this case, the mobile unit 1 is installed on a foundation.

[0024] Furthermore, the mobile unit 1 has passed vehicle inspection and is sized within legal regulations (Building Standards Act, Road Transport Vehicle Act) (Safety Standards Article 2 limits: vehicle width within 2.5 m, vehicle length within 12 m, vehicle height within 3.8 m). This allows the mobile unit 1 to be legally moved on public roads. However, with special permission, it may be possible to sized it larger than the limits. Furthermore, the mobile unit 1 shall meet all criteria required for placement at a fixed location.

[0025] The cart 2 is also called a chassis, and includes a support base 3 to which wheels 3 a are attached, and a plurality of support legs 4 that are detachably attached to the support base 3 . The box-shaped unit body of the mobile unit 1 is placed on and integrated with the support base 3. A connecting portion (not shown) that protrudes forward and is connected to an automobile is integrally formed at the front end of the support base 3. The support legs 4 are provided at a total of six locations: the four corners of the support base 3 and two locations near the wheels 3a (the center of the support base 3 in the longitudinal direction). The support legs 4 are jack devices that can be manually raised and lowered at the locations in contact with the support base 3.

[0026] [Mobile unit configuration] 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 a dolly 2, and the box-shaped unit main body placed on the support base 3 of the dolly 2 will be described below.

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

[0028] The floor 10, roof 11, and four side walls 12 to 15 are made of architectural wood panels used in the so-called panel construction method, which refers to a construction method in which building components such as walls, floors, and roofs are panelized in advance at a factory and then assembled at the construction site. Architectural wood panels have a hollow structure in which facings are attached to both sides or one side of a frame made of vertical and horizontal frame materials assembled into a rectangular shape, and the hollow interior is filled with fiber-based or foam-based insulation material. In this embodiment, architectural wood panels are used for the floor 10, roof 11, and four side walls 12 to 15 that form the outer shell of the mobile unit 1, and the mobile unit 1 is formed using a panel construction method, but this is not limited to this, and the mobile unit 1 may also be formed based on other building construction methods such as a frame construction method, a wall construction method, or a two-by-four construction method.

[0029] The floor 10 is long in one direction (front-rear direction) and short in the other direction (left-right direction), forming a rectangle in plan view. A floor finishing material (for example, flooring material) is appropriately provided on the upper surface to form the floor surface of the space within the mobile unit 1. Such a floor 10 is made up of a plurality of architectural wood panels. In addition, four side walls 12 to 15 are erected and fixed to the outer periphery of the floor 10.

[0030] The roof 11 is long in one direction (front-to-back) and short in the other direction (left-to-right), forming a rectangle in plan view. A ceiling material (e.g., decorative ceiling panel material) is appropriately provided on the underside, forming the ceiling surface of the space within the mobile unit 1. Furthermore, the roof is a single-sided sloping roof, with one side (the left) higher and the opposite side (the right) lower along the shorter side. This allows rainwater to be guided to one side. As will be described later, an entrance / exit 14a is provided on the left side of the unit body, preventing rainwater from flowing into the entrance / exit 14a. Because the roof 11 is sloped in this way, the ceiling of this embodiment is also a sloped ceiling sloping to one side. However, this is not limited to this, and a horizontal ceiling made of rafters, ceiling material, etc. may also be formed.

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

[0032] The four side walls include 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 on one end side (front end side) of the floor 10 in the length direction. The second side wall 13 is provided on the other end side (rear end side) of the floor 10 in the length direction. The third side wall 14 is provided between one end (left end) of the first side wall 12 in the width direction and one end (left end) of the second side wall 13 in the width direction. The fourth side wall 15 is provided between the other end (right end) of the first side wall 12 in the width direction and the other end (right end) of the second side wall 13 in the width direction. The first side wall 12 and the second side wall 13 form the front and rear surfaces of the unit body, respectively, and have a short width (dimension in the left-right direction). The third side wall 14 and the fourth side wall 15 form the left and right surfaces of the unit body, respectively, and have a long width (dimension in the front-to-back direction). Each of the four side walls 12 to 15 is made up of a plurality of architectural wood panels. The surfaces of the four side walls 12 to 15 are provided with exterior materials (e.g., galvalume steel sheets or siding materials), and the interior surfaces are provided with interior materials (e.g., gypsum boards) and wall finishing materials (e.g., wallpaper).

[0033] The third side wall 14 is formed with a doorway 14a with a fitting, the lower end of which is approximately the same height as the floor 10 and the upper end of which reaches the vicinity of the roof 11. The third side wall 14 also has a fixed window 14b set at the same height as the doorway 14a, which is provided next to the doorway 14a. The fitting of the doorway 14a and the fixed window 14b are both glass fittings and glass windows (glass walls).

[0034] The fourth side wall 15 is provided with a pair of opening / closing windows 15a, which are waist-high windows with their lower ends positioned higher than the floor 10, and a fixed window 15b, which cannot be opened or closed. Both the opening / closing window 15a and the fixed window 15b are glass windows.

[0035] [Regarding the interior space of the mobile unit] The rear part of the interior space of the mobile unit 1 is a living space 20 that can be used as a living room. More specifically, it can be used as a living room and bedroom. Therefore, the living space 20 is provided with living room equipment and bed equipment that can function as both living room furniture and bedroom furniture.

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

[0037] The living room equipment includes a plurality of movable benches 21 that are provided on the floor 10 and can be moved by casters 22a. The movable bench 21 is treated as a bench when the living space 20 is used as a living room, and is treated as a lower bunk when the living space 20 is used as a bedroom. Furthermore, although the number of movable benches 21 is six in this embodiment, it may be nine or any other number.

[0038] The movable bench 21 comprises a box-shaped storage section 22 that has a plurality of casters 22a attached to its underside and opens upward, and a lid 23 that closes the opening of the box-shaped storage section 22. In other words, by removing the lid 23, the opening can be opened and items can be stored in the box-shaped storage section 22, and by closing the opening with the lid 23, the box-shaped storage section 22 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 a plan view, with each side having the same length. The length of each side is approximately equal to the length of the short side of the internal space of the mobile unit 1 divided into three (equally divided). Therefore, when three movable benches 21 are lined up, they can be fitted snugly between the third side wall 14 and the fourth side wall 15. In this embodiment, six movable benches 21 are used, which means that two rows of three movable benches 21 can be arranged. By arranging these two rows of movable benches 21 closer to the second side wall 13 as shown in Fig. 5, these multiple movable benches 21 can be used as lower beds.

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

[0041] Furthermore, because the movable benches 21 are movable, multiple movable benches 21 can be freely combined and used. For example, as shown in Fig. 6, by arranging them in a J-shape in plan view, they can be used like a sofa. Alternatively, they can be arranged in an L-shape in plan view, or they can be scattered with spaces between them.

[0042] The multiple movable benches 21 may also include a movable bench / table. This movable bench / table has a lid 23 that has a cover plate and a protrusion that is integrally formed on the underside of the cover plate and is stored in a box-shaped storage section. When the protrusion is stored in the box-shaped storage section, the movable bench / table can be in a bench state with the upper surface of the cover plate as a seat, and when the lid is turned upside down and the cover plate is placed on the edge of the box-shaped storage section, the movable bench / table can be in a table state with the upper surface of the protrusion as a top surface. When the movable bench / table is in table mode, it can be easily used as a table because the height of the top surface is higher than that of the other movable benches 21. Also, when in bench mode, 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, a third side wall 14 and a fourth side wall 15 arranged perpendicular to both sides of the second side wall 13, and a bed support portion 25 arranged at the same height position relative to the three side walls 13, 14, 15, and adjacent to them in a U-shape (J-shape), and a bed 26 supported by the bed support portion 25.

[0044] The bed support portion 25 has a frame body 25a formed by assembling vertical and horizontal frame members into a rectangular shape, and a perforated board 25b that covers the side surface of the frame body 25a facing the living space 20 and the front end surface. 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. In other words, the upper and lower surfaces of the bed support part 25 are in a state where the upper and lower surfaces of the frame body 25a are exposed. The perforated board 25b is a surface material with numerous punched holes formed through it in the thickness direction, and thin metal linear members such as wires or hook members can be passed through the punched holes and hung on it. This allows furniture or the like having linear members as hanging parts or hook members to be hung on the surface of the bed support part 25. Since the upper surface of the frame body 25a is the surface that the bed 26 contacts, it is preferable that the height position of the upper edge of the perforated board 25b be 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] Of 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 that is approximately half the length from the second side wall 13 to the fixed window 14b. Specifically, the width dimension is set to approximately 850 to 900 mm, and it does not reach the fixed window 14b. In addition, the height dimension of this bed support portion 25 is set to approximately 700 mm, and it is positioned so that its upper end surface is 1,400 mm above the floor 10.

[0046] On the other hand, the bed support portion 25 on the fourth side wall 15 side has a width equal to the length from the second side wall 13 to the fixed window 15b. Therefore, it is set to have a width larger than that of the bed support portion 25 on the third side wall 14 side. Specifically, it is set to have a width of about 2100 mm, reaching the fixed window 15b. In addition, the height of this bed support portion 25 is set to about 700 mm, and it is positioned so that its upper end surface is 1400 mm above the floor 10.

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

[0048] A convex portion 25c that protrudes upward is fixed to the upper surface of the front end portion of the bed support portion 25 on the third side wall 14 side. A similar protrusion 25c is fixed to the upper surface of the front end of the bed support portion 25 on the fourth side wall 15 side. Both protrusions 25c are located at the same position in the front-rear direction of the mobile unit 1.

[0049] The bed 26 is placed on the top surfaces of the three bed support parts 25 adjacent to each other in a U-shape (J-shape) and is installed so as to span these three bed support parts 25. Therefore, the bed 26 is recognized as an upper bed 26 in comparison with a lower bed made up of multiple movable benches 21. However, if the multiple movable benches 21 are not used as lower beds, the bed 26 is simply recognized as a bed 26. Such a bed 26 includes a first bed plate 27 that spans the bed support portions 25 on three sides, and a second bed plate 28 that spans two parallel bed support portions 25 of the three bed support portions 25. In other words, the bed 26 is divided into two in the 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] The bed 26 also has a handrail 29 provided at the front end of the second bed plate 28 at a position that avoids a ladder hook 31, which will be described later. The handrail 29 may be configured to be foldable in a direction that overlaps the upper surface of the second bed plate 28.

[0051] Such a bed 26 can be used as a bed 26 by arranging the first bed plate 27 and the second bed plate 28 side by side. In addition, the first bed plate 27 and the second bed plate 28 can be stacked and arranged close to the central second side wall 13, so that they can be used as if they were a wall-mounted shelf.

[0052] The first bed plate 27 is a plate formed in a rectangular shape in a plan view, and is placed on and spans the bed support parts 25 fixed to the three side walls 13, 14, and 15. The first bed plate 27 is provided in contact with the second side wall 13. In this embodiment, the first bed plate 27 is simply placed on each of the bed support parts 25 on the three sides, but it may also be placed on each of the bed support parts 25 on the three sides and then fixed.

[0053] The second bed plate 28 is a plate formed in a rectangular shape in a plan view, and is placed across the bed support parts 25 fixed to the third side wall 14 and the fourth side wall 15, among the bed support parts 25 fixed to the three side walls 13, 14, and 15. Note that the second bed plate 28 is simply placed on the two parallel bed support parts 25, and is not fixed to the bed support parts 25.

[0054] The lengthwise dimension of the first bed plate 27 and the second bed plate 28 is set to a width of approximately 2000 to 2100 mm, and the widthwise dimension is set to approximately 440 mm. The thickness of the first bed plate 27 and the second bed plate 28 is set to 50 mm. Therefore, the widthwise dimension of the bed 26 formed by arranging the first bed plate 27 and the second bed plate 28 side by side is set to approximately 880 mm. In other words, the bed 26 is about the same size as 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 are connected to each other when they are arranged side by side and used as a bed . More specifically, a groove 27a is formed in the end surface of the first bed plate 27 facing the second bed plate 28. The groove 27a is formed long along the length of the first bed plate 27, and both ends of the groove 27a in the length direction are open. Furthermore, a convex rib portion 28a is provided on the end surface of the second bed plate 28 facing the first bed plate 27. The convex rib portion 28a is made of an aluminum block, and is inserted into a concave groove formed on the end surface of the second bed plate 28 facing the first bed plate 27, and is fixed with a fixing material such as a screw. The convex rib portion 28a is formed long along the length direction of the second bed plate 28. The first bed plate 27 is integrally connected by inserting the ridge 28a of the second bed plate 28 into the groove 27a of the first bed plate 27. In other words, the bed 26 is provided with a recessed / projecting fitting structure consisting of the groove 27a and the ridge 28a as a connecting means for detachably connecting the end of the first bed plate 27 facing the second bed plate 28 and the end of the second bed plate 28 facing the first bed plate 27. However, the form of the connecting means is not limited to this recessed / projecting fitting structure, and can be changed as appropriate, for example, by using a latch or 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 board 27 on the first bed board 27 side and to the groove bottom face of the recessed groove portion 27a. A felt surface material is attached to the opposite end face as vibration-proofing material 27c. That is, vibration-proofing material 27c is provided on the end face of first bed plate 27 on the second side wall 13 side, and is interposed between first bed plate 27 and second side wall 13. This protects the surface of second side wall 13.

[0057] A melamine decorative board is attached to the end face of the second bed board 28 on the second bed board 28 side and the opposite end face as a decorative board 28b. A felt surface material is attached to the end surface of the protruding ridge portion 28a in the protruding direction as a vibration-damping material 27c. That is, the vibration-damping material 28c contacts the bottom surface of the recessed groove portion 27a in the first bed plate 27, thereby protecting the recessed groove portion 27a. Furthermore, the vibration-damping material 28c on the end surface of the protruding ridge portion 28a in the protruding direction contacts the second side wall 13 when the second bed plate 28 is stacked on the first bed plate 27, thereby protecting the surface of the second side wall 13.

[0058] Furthermore, insertion holes 28d are formed on the underside of both longitudinal ends of the second bed plate 28. As shown in Figures 4 and 6, these insertion holes 28d are holes into which protrusions 25c are inserted, which are provided on the upper surfaces of the bed support parts 25 on the third side wall 14 side and the fourth side wall 15 side. When the bed 26 is in use, the protrusions 25c of the bed support parts 25 are inserted into the insertion holes 28d on the underside of the second bed plate 28, thereby preventing the bed 26 from shifting position.

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

[0060] [About living style in the living space] In the living space 20 of the mobile unit 1 configured as described above, residents can live in a way that suits their own style by moving the multiple movable benches 21 and changing the shape of the bed 26.

[0061] For example, Figure 5 shows a sleeping style for multiple occupants, in which six movable benches 21 are gathered together on the second side wall 13 side and can be used as beds. Of the movable benches 21, three of the movable benches 21 on the first side wall 12 side have their casters 22a locked.

[0062] A bed 26 of the bed facility is provided above a bed consisting of multiple movable benches 21. That is, a first bed plate 27 and a second bed plate 28 are arranged side by side and can be used as the bed 26. The convex strip 28a of the second bed plate 28 is inserted into the concave groove 27a of the first bed plate 27, so that the first bed plate 27 and the second bed plate 28 are integrally connected. Furthermore, the convex portion 25c on the upper surface of the bed support portion 25 on the third side wall 14 side and the convex portion 25c on the upper surface of the bed support portion 25 on the fourth side wall 15 side are inserted into insertion holes 28d formed on the underside of both longitudinal ends of the second bed plate 28, so that the bed 26 is installed stably.

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

[0064] FIG. 6 shows a style in which the living space 20 is used as a living room, with six movable benches 21 arranged in a roughly J-shape in plan view, allowing several residents to sit at the same time.

[0065] Furthermore, the bed 26 has the second bed plate 28 stacked on top of the first bed plate 27, which reduces the projection dimension of the bed 26 from the second side wall 13. Therefore, a resident sitting on the movable bench 21 located below the first bed plate 27 is less likely to feel pressured by the first bed plate 27 while 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, and multiple movable benches 21 can be used together, or one or multiple movable benches 21 can be used spaced apart from the other movable benches 21. The bed 26 can also be used as a shelf by normally stacking the second bed plate 28 on top of the first bed plate 27, and when guests come over, the second bed plate 28 can be unfolded and used as the bed 26.

[0067] [Room structure development] The room structure of this embodiment is applied to the interior space of a mobile unit 1 transported by automobile, but is not limited to this and may be applied to rooms in ordinary buildings such as detached houses, apartment buildings, etc. In addition, it may be applied to passenger rooms in sleeper trains or ships, for example. Furthermore, although the bed 26 of this embodiment is supported by spanning three adjacent bed support parts 25 that are U-shaped in plan view, both the first bed plate 27 and the second bed plate 28 may be supported by spanning two parallel bed support parts 25. In this 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, thereby preventing misalignment of both the first bed plate 27 and the second bed plate 28. If a bed 26 that is supported by spanning two parallel bed support parts 25 can be used, multiple beds 26 can be arranged side by side in the living space 20. Furthermore, 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] [About the effects] According to this embodiment, the following excellent effects are achieved. That is, the bed 26 is equipped with a first bed plate 27 that is hung across the bed support parts 25 on three sides, and a second bed plate 28 that is adjacent to the first bed plate 27 and hung between two of the bed support parts 25 on the three sides that are parallel to each other, so that the second bed plate 28 can be removed from the two bed support parts 25 on both sides, and the first bed plate 27 can be removed from the bed support parts 25 on the three sides. As a result, by stacking the second bed plate 28 on top of the first bed plate 27 or removing both the first bed plate 27 and the second bed plate 28 from the bed support parts 25 on the three sides, the dimension of the bed 26 that protrudes towards the center of the room can be reduced, and the living space of the room is less likely to become narrower.

[0069] Furthermore, the bed 26 is further provided with a connecting means for detachably connecting the end of the first bed plate 27 facing the second bed plate 28 to the end of the second bed plate 28 facing the first bed plate 27. Therefore, when the first bed plate 27 and the second bed plate 28 are connected and used as the bed 26, the unity of the first bed plate 27 and the second bed plate 28 is increased, and the first bed plate 27 and the second bed plate 28 can be used stably without bending separately. Furthermore, the first bed plate 27 and the second bed plate 28 can be easily attached and detached, so when you want to expand the living space of the room or when you go to sleep, there is no time-consuming task of removing or connecting the first bed plate 27 and the second bed plate 28. This allows you to quickly expand the living space of the room or use the bed 26 immediately.

[0070] Furthermore, the underside of both longitudinal ends of the second bed plate 28 is formed with insertion holes 28d into which the protrusions 25c provided on the upper surfaces of the two bed support parts 25 are inserted, so that when the second bed plate 28 is placed across the two bed support parts 25, the protrusions 25c are inserted into the insertion holes 28d, making it difficult for the second bed plate 28 to shift position. If it is desired to expand the living space of the room, the second bed plate 28 can be removed so that the protrusions 25c can be removed from the insertion holes 28d, and the living space of the room can be immediately expanded.

[0071] Furthermore, bed support section 25 has frame 25a fixed to the inner wall surfaces of side walls 13, 14, and 15, and perforated board 25b attached to the surface of frame 25a, so that any item that can be hung on the holes in perforated board 25b can be hung on perforated board 25b and stored. This makes bed support section 25 highly convenient as it has both the function of supporting bed 26 and the function of storing items, and being able to store items in this way prevents the living space from becoming cramped.

[0072] In addition, the multiple movable benches 21 are gathered together on the side wall 13 located in the middle of the three side walls 13, 14, 15 to form a bed, and can be used as a bunk bed together with the bed 26 supported by the bed support parts 25 on the three sides. Furthermore, the multiple movable benches 21 can be freely moved on the floor 10 and used in various forms, which is very convenient.

[0073] Furthermore, since the room structure is the internal space of the mobile unit 1, which is formed in a box shape and placed on the cart 2 for transport by automobile, by employing the bed 26 equipped with the first bed plate 27 and the second bed plate 28, the living space of the room is less likely to become narrow, even in a mobile unit 1 with only a limited room space. That is, by stacking the second bed plate 28 on top of the first bed plate 27, or by removing both the first bed plate 27 and the second bed plate 28 from the bed support parts 25 on three sides, the dimension of the bed 26 that protrudes toward the center of the room can be reduced, and the living space of the room of the mobile unit 1 is less likely to become narrow.

[0074] Furthermore, in recent years, there has been a demand for the realization of a carbon-neutral society by promoting carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and for the achievement of the SDGs (Sustainable Development Goals), and in the construction industry, efforts are being made to build buildings using wood, which reduces carbon dioxide emissions.The mobile unit 1 of this embodiment has an outer shell made of architectural wood panels, so it can contribute to the realization of a carbon-neutral society by promoting carbon neutrality, and the achievement of the SDGs (Goals 7, 12, 13, etc.).
