Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, since the unit furniture is large, each unit is brought into the house and assembled in the room where the unit furniture is used. Among the units constituting the unit furniture, the staircase unit is a relatively large part, difficult to transport and difficult to handle during assembly. However, when assembling the staircase on site, the number of parts is large and the assembly work is troublesome.

[0005] This invention was made in view of the above circumstances, and its objective is to minimize the number of parts that make up a staircase and to facilitate the assembly of the staircase. [Means for solving the problem]

[0010] Claim 1 The invention described above relates to a unit furniture 10 that is installed in a room 1, as shown in Figures 1 to 3, Figure 7, etc., A floor unit 11 is positioned above a portion of the floor 2 of the aforementioned room 1, A plurality of leg units 12, 13 are installed on the floor 2 and support the floor unit 11, It has a stair section 18 attached to one of the plurality of leg units 12, 13, The leg unit 13 to which the aforementioned stair section 18 is attached has a plurality of vertical plates (back plate 131, side plates 132, 133) arranged perpendicular to the floor 2, The aforementioned staircase section 18 is attached to the vertical plates 132 and 133, which are among the plurality of vertical plates 131, 132, and 133, and are arranged in a plan view along the direction of ascent and descent of the staircase section 18. A first connecting plate 15 connects the leg units (first leg units 12, 12) which are arranged at intervals in the first direction (front-to-back direction), The invention is characterized by comprising a second connecting plate 16 that connects the leg units (first leg unit 12 and second leg unit 13) which are arranged at intervals in a second direction (left-right direction) perpendicular to the first direction.

[0011] Claim 1 According to the invention described, The leg units 12, 13, and 14 have vertical plates positioned perpendicular to the floor 2. Of the multiple floor bodies 11a, 11b, and 11c that make up the floor unit 11, two adjacent floor bodies are fixed to the same vertical plate. This reduces the number of vertical plates compared to the case where two adjacent floor bodies are not fixed to the same vertical plate (i.e., they are fixed to different vertical plates). Therefore, inconveniences such as difficulty entering and exiting the lower space 10a due to the numerous vertical plates supporting the floor unit 11 are avoided, making it easier to enter and exit the lower space 10a and improving usability. Also,The unit furniture 10 is equipped with a first connecting plate 15 that connects the leg units 12, 12 which are spaced apart in the first direction (front-to-back direction), and a second connecting plate 16 that connects the leg units 12, 13 which are spaced apart in the second direction (left-to-right direction) perpendicular to the first direction. This suppresses horizontal wobbling of the unit furniture 10, making it possible to move and work comfortably on the floor unit 11.

[0012] Claim 2 The invention described above is as shown in Figures 1, 7, etc., as described in the Claims 1 In the unit furniture 10 described above, The first connecting plate 15 and the second connecting plate 16 can be used as a counter desk. The upper surface of the first connecting plate 15 and the upper surface of the second connecting plate 16 are set at the same height.

[0013] Claim 2 According to the invention described above, the first connecting plate 15 and the second connecting plate 16 can be used as a counter desk, and since the top surface of the first connecting plate 15 and the top surface of the second connecting plate 16 are set at the same height, it is easy to use, improves work efficiency when working between the first connecting plate 15 and the second connecting plate 16, and also looks good.

[0014] Claim 3 The invention described above relates to a unit furniture 10 that is installed in a room 1, as shown in Figures 2, 4, 7, 8, etc. A floor unit 11 is positioned above a portion of the floor 2 of the aforementioned room 1, A plurality of leg units 12, 13 are installed on the floor 2 and support the floor unit 11, It has a stair section 18 attached to one of the plurality of leg units 12, 13, The leg unit 13 to which the aforementioned stair section 18 is attached has a plurality of vertical plates (back plate 131, side plates 132, 133) arranged perpendicular to the floor 2, The step portion 18 is attached to the vertical plate bodies 132 and 133 that are arranged along the elevating direction of the step portion 18 in a plan view among the plurality of vertical plate bodies 131, 132, and 133. The step portion 18 is attached to at least two of the plurality of leg units 12 and 13. The at least two leg units 13 are characterized in that they are connected by a tread beam (side plate 18c) in the step portion 18.

[0015] Claim 3 According to the invention described in The leg units 12, 13, and 14 have vertical plates positioned perpendicular to the floor 2. Of the multiple floor bodies 11a, 11b, and 11c that make up the floor unit 11, two adjacent floor bodies are fixed to the same vertical plate. This reduces the number of vertical plates compared to the case where two adjacent floor bodies are not fixed to the same vertical plate (i.e., they are fixed to different vertical plates). Therefore, inconveniences such as difficulty entering and exiting the lower space 10a due to the numerous vertical plates supporting the floor unit 11 are avoided, making it easier to enter and exit the lower space 10a and improving usability. Also, Since at least two leg units 13 to which the step portion 18 is attached are connected by a tread beam 18c in the step portion 18, the wobbling of the unit furniture 10 can be suppressed by the member (tread beam 18c) constituting the step portion 18. Therefore, it is possible to suppress wobbling without providing a dedicated member between at least two leg units 13 to which the step portion 18 is attached, so that the number of parts of the unit furniture 10 can be reduced as much as possible.

Effect of the Invention

[0016] According to the present invention, the number of parts constituting the step portion can be reduced as much as possible, and the assembly of the step portion can also be easily performed.

[Figure 7] This is a perspective view showing the general configuration of the modular furniture. [Figure 8] This diagram illustrates the relationship between the second leg unit and the staircase section. [Modes for carrying out the invention]

[0018] Embodiments of the present invention will be described below with reference to the drawings. However, while the embodiments described below are subject to various technically preferred limitations for carrying out the present invention, the technical scope of the present invention is not limited to the following embodiments and illustrated examples. The directions in the following embodiments and illustrated examples are set solely for the convenience of explanation.

[0019] In Figures 1 to 4, reference numeral 1 indicates a room. This room 1 is located inside a building such as a house and comprises a floor 2 (floor 2), a pair of opposing walls 3 and 4 (walls 3 and 4), another wall 5 (wall 5) perpendicular to the pair of walls 3 and 4, and a ceiling. The space enclosed by the floor 2, walls 3, 4, and 5, and the ceiling constitutes the room space of room 1. Unit furniture 10 is placed and installed on the floor 2 of room 1.

[0020] Of the pair of walls 3 and 4, wall 3 is located on the left side when the unit furniture 10 is viewed from the front, and the other wall 4 is located on the right side. The other wall 5 is located on the rear side of the unit furniture 10. Therefore, in the following explanation, the wall 3 located on the left side will be referred to as the left wall 3 (left wall 3), the wall 4 located on the right side will be referred to as the right wall 4 (right wall 4), and the other wall 5 located on the rear side will be referred to as the rear wall 5 (rear wall 5).

[0021] Each of the walls 3, 4, and 5 is pre-finished with wall coverings (not shown), baseboards 7, and moldings (not shown), and the floor 2 is also pre-finished with flooring materials and mats. The unit furniture 10 is then installed in room 1, which is equipped with these walls 3, 4, and 5 and floor 2. Therefore, when installing the unit furniture 10 in room 1, it is necessary to carry out the work in a way that does not damage these finishes.

[0022] The unit furniture 10 is a freestanding piece of furniture that is placed in Room 1 and is not fixed to the building structure. In other words, the unit furniture 10 has no mechanical connection to the building structure (such as fasteners like screws, adhesives, or various metal fittings), and is not built into the building structure. In short, although the unit furniture 10 is in contact with the floor and walls of Room 1, it is simply a piece of furniture that is placed in Room 1, and can be placed in rooms of various buildings, including so-called detached houses, apartment buildings and other multi-unit dwellings, and commercial buildings such as offices and office buildings. Since the modular furniture 10 is not joined to the building structure, the structure of the building on which the modular furniture 10 is installed is not particularly limited. In other words, the building structure may be made of wood, steel, reinforced concrete, or steel-reinforced concrete, and the type of construction method (post-and-beam construction, wall-type construction, rigid frame construction, etc.) is not particularly limited. In short, since there is no need to join the modular furniture 10 to the building structure, there is no need to consider compatibility when joining the modular furniture 10 to the building structure.

[0023] The unit furniture 10 itself is a prefabricated furniture that can be assembled on-site, and fasteners such as screws, adhesives, and various metal fittings are used as appropriate to join the components that make up the furniture. Specifically, as shown in Figures 1 to 4, the modular furniture 10 has a basic configuration comprising a floor unit 11, leg units 12 and 13 (first leg unit 12 and second leg unit 13) that support the floor unit 11, and a staircase section 18 that connects the floor surface 2 of room 1 and the upper surface of the modular furniture 10. Spaces 10a and 10b are formed above and below the floor unit 11. In this embodiment, the lower space 10a can be used as a single room (a space with a ceiling height that can be used as a living room) that can be accessed from within room 1, and the upper space 10b can be used as a low-ceiling storage space. Depending on the height dimensions of the leg units 12 and 13, the lower space 10a may be used as a low-ceiling storage space and the upper space 10b as a single room, or both the lower space 10a and the upper space 10b may be used as a single room or a low-ceiling storage space. Furthermore, in this embodiment, the unit furniture 10 includes, in addition to the basic configuration described above, a top plate 14, connecting plates 15 and 16, and a handrail unit 17.

[0024] The floor unit 11 is made of floor structural materials, and it is possible for people to stand on its top surface, as well as for heavy objects to be placed on it. In this embodiment, the floor unit 11 is made of wooden building panels used in the so-called wood panel bonding method, and has structural strength comparable to that of the building frame on which the unit furniture 10 is placed. A building panel is constructed by assembling vertical and horizontal frame members into a rectangular shape, and then assembling auxiliary crossbars vertically and horizontally within the rectangular frame to form a frame body. Face material is attached to one or both sides of this frame body, resulting in a hollow internal structure. Furthermore, insulation material such as glass wool or rock wool is usually installed in the hollow internal portion.

[0025] In this embodiment, wooden building panels are used as floor structural materials, but the material is not limited to these. Laminated timber such as CLT (Cross Laminated Timber), load-bearing wall panels used in two-by-four construction, thick structural plywood with a predetermined thickness (e.g., 24 mm or more), single planks of a predetermined thickness, or reinforced concrete panels (RC or S) may also be used.

[0026] The floor unit 11 is composed of floor bodies (architectural panels 11a, 11b for flooring) and is installed above a portion of the floor surface 2, with a width dimension set to be slightly shorter than the distance between the left wall surface 3 and the right wall surface 4. Multiple building floor panels 11a and 11b (hereinafter referred to as building floor panels 11a and 11b) are used and are installed at a predetermined height above a portion of the floor surface 2 of room 1, rather than covering the entire surface. In this embodiment, multiple building floor panels 11a and 11b are installed at a height position such that the height from the floor surface 2 to the top surface of the floor unit 11 (floor surface material 19a) is 1.6m to 1.8m. The height position at which the height from the floor surface 2 to the top surface of the floor unit 11 (floor surface material 19a) is 1.6m to 1.8m is the height range that ensures the minimum height at which a person can enter the lower space 10a in a standing position and walk and work. In other words, in this embodiment, the ceiling height of the lower space 10a is set to a size that allows a person to walk and work in a standing position, and the ceiling height of the upper space 10b is set to a size that allows a person to walk and work in a bent-over position, so that the upper space 10b can be used like a loft. However, this is not the only option, and the ceiling height may be set arbitrarily according to the ceiling height of room 1. For example, if room 1 has an open space and the ceiling height of room 1 is high, the ceiling heights of both the lower space 10a and the upper space 10b may be set to a size that allows a person to walk and work in a standing position. Conversely, the ceiling heights of both the lower space 10a and the upper space 10b may be set to a size that allows a person to walk and work in a bent-over position. In short, since the unit furniture 10 is, after all, furniture, there are no particular restrictions on the vertical height in the lower space 10a and the upper space 10b, and it can be set arbitrarily. The building floor panels 11a and 11b are connected to each other using tools such as screws, bolts, and nuts, thereby forming a floor unit 11.

[0027] As shown in Figures 5 and 6, the floor unit 11 is composed of building floor panels 11a and 11b and is formed in a rectangular shape overall. An access opening 20 is provided on the right side of the floor unit 11, connecting the lower space 10a and the upper space 10b. Although the building floor panels 11a and 11b differ in shape and size, their basic configuration includes a plurality of frame members 110, a plurality of auxiliary cross members 112, and a surface material 111 fixed to the upper surface of a frame formed by combining these frame members 110 and auxiliary cross members 112. The building floor panel 11a (first building floor panel 11a) located on the left side is positioned so that the length of the auxiliary support member 112 is aligned with the front-to-back direction. The building floor panels 11b, 11b (second building floor panels 11b, 11b) located on the right side are arranged front to back so that the length of the auxiliary bracing members 112 is aligned with the left to right direction. Furthermore, the dimensions of the second building floor panel 11b are set to be longer in the left to right direction than the first building floor panel 11a, and the dimensions in the front to back direction are set to be half that of the first building floor panel 11a.

[0028] The first leg unit 12 is one of the multiple leg units 12, 13 that does not have a stair section 18 attached, and in this embodiment, it is provided at the two left corners of the four corners of the floor unit 11 to support the floor unit 11. The first leg unit 12 has at least a back plate 121 and left and right side plates 122, and in plan view it is roughly U-shaped. The height dimension of the side plates 122 is set to be longer than the height dimension of the back plate 121. That is, the upper part of the first leg unit 12 (the part above the first connecting plate 15) does not have a back plate, and the line of sight is unobstructed in the front-to-back direction. The first leg unit 12 is also configured to support the floor unit 11 with the left and right side plates 122. In this embodiment, the height dimension of the first leg unit 12 (specifically the side plates 122, 122) is set so that the height from the floor surface 2 to the top surface of the floor unit 11 (floor surface material 19a) is 1.6m to 1.8m.

[0029] In this embodiment, the first leg unit 12 located below the rear end (back side end) of the floor unit 11 is used in a state that is roughly U-shaped in plan view, consisting of a back plate 121 and left and right side plates 122. On the other hand, the first leg unit 12 located below the front end (front side end) of the floor unit 11 has a shelf board 123 at its upper part (the part above the first connecting plate 15), and can be used as storage furniture. The rear first leg unit 12 may also have a shelf board 123.

[0030] The plates 121 to 123 that make up the first leg unit 12 are connected using tools such as screws, bolts, and nuts, thereby forming the first leg unit 12. The back plate 121 and the side plates 122, 122 have a roughly U-shape in plan view. The shelf plate 123 is positioned higher than the back plate 121, and the shelf plate 123 and the side plates 122, 122 are connected with the left and right end faces of the shelf plate 123 and the opposing faces of the side plates 122, 122 (the mutually opposing faces of the side plates 122, 122) in contact. The number of shelves 123 is not limited to two; there may be one or more. Also, the shelves 123 may be adjustable. Furthermore, the shelves 123 may be located at the bottom of the first leg unit 12 (the part below the first connecting plate 15). The plates 121 to 123 that constitute the first leg unit 12 may be made of board material such as MDF (Medium density fiberboard, JIS A5905) or particleboard (JIS A5908), or they may be made of these board materials in a flush structure or a solid core structure, and can be selected as appropriate.

[0031] The second leg unit 13 is one of the multiple leg units 12, 13 to which the stair section 18 is attached. In this embodiment, it is provided at the two right-hand corners of the four corners of the floor unit 11 to support the floor unit 11. The second leg unit 13 has a back panel 131 and left and right side panels 132 and 133, and in plan view it is roughly U-shaped. Of the left and right side panels 132 and 133, the first side panel 132 is located on the left side (towards the center of the unit furniture 10), and the second side panel 133 is located on the right side. The second leg unit 13 supports the floor unit 11 with the first side plate 132, which is one of the plate bodies 131 to 133 that make up the second leg unit 13, and has an access opening 20 between the first side plate 132 and the second side plate 133 that connects the lower space 10a and the upper space 10b. In other words, the space between the first side plate 132 and the second side plate 133 is the access opening 20.

[0032] Thus, the first leg unit 12 supports the floor unit 11 with its left and right side plates 122, while the second leg unit 13 supports the floor unit 11 with only its first side plate 132. Therefore, the second leg unit 13 in this embodiment further includes a reinforcing plate 134 to reinforce the first side plate 132. This reinforcing plate 134 is fixed to the left side of the first side plate 132 (the side facing the center of the unit furniture 10). In other words, the left side plate (the side facing the center) of the left and right side plates of the second leg unit 13 can be said to be constructed by stacking two plates.

[0033] The first side plate 132 and the reinforcing plate 134 are set to the same height dimension as the side plate 122 of the first leg unit 12. Furthermore, the height dimension of the second side panel 133 is set to be longer than that of the first side panel 132. In this embodiment, the height dimension of the second side panel 133 is set such that the upper end surface of the second side panel 133 is at approximately the same height as the upper surface of the floor unit 11 (floor surface material 19a). Furthermore, the height dimension of the back panel 131 is set to be shorter than that of the first side panel 132. In this embodiment, the height dimension of the back panel 131 of the rear second leg unit 13 of the front and rear second leg units 13 is set to such a dimension that the uppermost step 18a of the stair section 18 rests on the upper end surface of the back panel 131.

[0034] The plates 131 to 134 that make up the second leg unit 13 are connected using tools such as screws, bolts, and nuts, thereby forming the second leg unit 13. The plates 131 to 134 that make up the second leg unit 13 may be made of board material such as MDF or particleboard, similar to the plates 121 to 123 that make up the first leg unit 12, or they may be made of these board materials in a flush structure or a solid core structure, and can be selected as appropriate.

[0035] The modular furniture unit 10 is equipped with multiple tabletops 14, and the tabletops 14 are shared between the leg units 12 and 13, which are arranged in the front-to-back direction. In other words, the tabletop 14 located on the left side is provided by spanning across the upper surfaces of the first leg units 12, which are spaced apart in the front-to-back direction on the left side. The length dimension (front-to-back dimension) of the tabletop 14 located on the left side is set to be approximately equal to the depth dimension (front-to-back dimension) of the floor unit 11. The tabletop 14 located on the right side is installed by spanning across the upper surfaces of the second leg units 13, which are spaced apart in the front-to-back direction on the right side. Since there is no tabletop 14 at the entrance 20, the shape and size of the tabletop 14 located on the right side differ from those of the tabletop 14 located on the left side.

[0036] Furthermore, the central side edge of the top plate 14 protrudes towards the center. Specifically, as shown in Figure 5, for example, the left top panel 14 protrudes to the right of the right side panel 122 of the first leg unit 12. In other words, the right edge (central side edge) of the left top panel 14 extends out to the right (towards the center of the unit furniture 10). Furthermore, the right-side top panel 14 protrudes to the left more than the reinforcing plate 134 of the second leg unit 13. In other words, the left edge (central edge) of the right-side top panel 14 is projected to the left (towards the center of the unit furniture 10).

[0037] The tabletop 14 is composed of a first decorative panel 14a and a second decorative panel 14b, with the second decorative panel 14b positioned inward (towards the center of the unit furniture 10) compared to the first decorative panel 14a. In other words, the second decorative panel 14b protrudes towards the center compared to each leg unit 12, 13. The first decorative panel 14a may be made of a board material such as MDF or particleboard, or it may be made of such board material in a flush structure or a solid core structure, and can be selected as appropriate. Furthermore, the second decorative panel 14b may be made of board material such as MDF (JIS A5905) or particleboard (JIS A5908), or it may be made of these board materials in a flush structure or a solid core structure, and can be selected as appropriate. Furthermore, the first decorative panel 14a and the second decorative panel 14b may be made of board material with different strengths, in which case the second decorative panel 14b will be made of a board material with higher strength than the first decorative panel 14a. Since no top panel 14 is provided at the entrance 20, the top panel 14 located on the right side is composed solely of the second decorative panel 14b.

[0038] The leg units 12 and 13 are joined to the tabletop 14 (first decorative panel 14a, second decorative panel 14b) using tools such as screws, bolts, and nuts. For example, in this embodiment, the tabletop 14 is fixed to the leg units 12 and 13 with screws. The floor unit 11 is then placed on top of the top plates 14 that are arranged side by side. Specifically, as shown in Figure 5, for example, the first building floor panel 11a is fixed to the upper surface of the top plate 14 that spans between the left first leg units 12. The second building floor panel 11b is spanned and fixed between the upper surface of one top plate 14 and the upper surface of the other top plate 14. More specifically, the left end of the second building floor panel 11b is fixed to the upper surface of the second decorative panel 14b on the left top plate 14, and the right end is fixed to the upper surface of the second decorative panel 14b on the right top plate 14.

[0039] The top plate 14 and the floor unit 11 are joined using tools such as screws, bolts, and nuts. For example, in this embodiment, the floor unit 11 (architectural floor panels 11a, 11b) is fixed to the top plate 14 with screws. In this embodiment, since the top plate 14 protrudes towards the center more than the left and right leg units 12 and 13, it is possible to ensure a length that allows easy access to the lower space 10a as the distance between the left leg unit 12 and the right leg unit 13 (i.e., the width dimension of the opening for entering and exiting the lower space 10a), while preventing the second building floor panel 11b from falling off. In addition, distortion and bending of the top plate 14 can be prevented, improving the stability of the floor unit 11.

[0040] The first connecting plate 15 is installed by spanning between the first leg units 12, 12 which are spaced apart in the front-to-back direction on the left side, and can be used, for example, as a counter desk or shelf. Of the front and rear first leg units 12, the front first leg unit 12 is positioned so that its back plate 121 faces forward, and the rear first leg unit 12 is positioned so that its back plate 121 faces rear. In other words, the front and rear first leg units 12 are positioned so that the open ends on the opposite side of the back plate 121 face each other. A first connecting plate 15 is then placed and fixed between the upper end surface of the back plate 121 of the front first leg unit 12 and the upper end surface of the back plate 121 of the rear first leg unit 12. The first connecting plate 15 is made of a decorative panel. The first connecting plate 15 may be made of board material such as MDF or particleboard, or it may be made of these board materials in a flush structure or a solid core structure, and can be selected as appropriate. The first leg unit 12 and the first connecting plate 15 are joined using tools such as screws, bolts, and nuts. For example, in this embodiment, the first connecting plate 15 is fixed to the first leg unit 12 with screws. The means of attaching the first connecting plate 15 to the first leg unit 12 are not particularly limited; for example, an angle material fixed to the first connecting plate 15 and the first leg unit 12 may be used, or a groove may be formed in the first leg unit 12 into which the end of the first connecting plate 15 is fitted, and the first connecting plate 15 may be fitted into the groove to attach it.

[0041] The second connecting plate 16 is installed by being placed between the first leg unit 12 and the second leg unit 13, which are spaced apart in the left-right direction at the rear, and can be used, for example, as a counter desk or shelf. The second connecting plate 16 is made of a decorative panel. The second connecting plate 16 may be made of board material such as MDF or particleboard, or it may be made of these board materials in a flush structure or a solid core structure, and can be selected as appropriate.

[0042] The second connecting plate 16 can be attached to the first leg unit 12 by, for example, using an angle material fixed to the lower surface of the second connecting plate 16 and the right side plate 122 of the first leg unit 12, or by forming a recessed groove on the right side surface of the right side plate 122 into which the end of the second connecting plate 16 is fitted and then fitting it into the groove. In other words, the means of attaching the second connecting plate 16 to the first leg unit 12 are not particularly limited, and it may be attached using tools such as screws, bolts and nuts. Furthermore, the attachment of the second connecting plate 16 to the second leg unit 13 may be similar to the attachment of the second connecting plate 16 to the first leg unit 12, for example, by using an angle material fixed to the lower surface of the second connecting plate 16 and the reinforcing plate 134 of the second leg unit 13, or by forming a recessed groove on the left side of the reinforcing plate 134 into which the end of the second connecting plate 16 is fitted, and then fitting it into the recessed groove. In other words, the means of attaching the second connecting plate 16 to the second leg unit 13 are not particularly limited, and it may be attached using tools such as screws, bolts and nuts.

[0043] The handrail unit 17 is a storage furniture type unit that can be used as storage furniture by a person on the upper surface (upper space 10b) of the floor unit 11. The handrail unit 17 is installed at the front end of the upper surface of the floor unit 11. The floor unit 11 and the handrail unit 17 are joined using tools such as screws, bolts, and nuts.

[0044] The handrail unit 17 has two side panels 171, multiple partition panels 172 that divide the space between the two side panels 171 to the left and right, a top panel 173, and a bottom panel 174. In other words, the handrail unit 17 does not have a back panel, and the line of sight is unobstructed in the front-to-back direction. Note that the number of partition panels 172 is not limited to two; there may be one or more. The plate bodies 171 to 174 that make up the handrail unit 17 are connected using tools such as screws, bolts, and nuts, thereby forming the handrail unit 17. In this embodiment, the handrail unit 17 is of the storage furniture type as described above, but it is not limited to this. For example, a simple handrail wall may be provided, or a fence-shaped handrail unit may be provided.

[0045] The staircase section 18 is formed in a box shape and comprises a plurality of treads 18a, a plurality of risers 18b, and two side plates 18c. The side plates (stringers) 18c are formed in a stepped shape when viewed from the side and constitute the left and right outer surfaces of the staircase section 18. The height dimension of the staircase section 18 takes into account the height from the floor surface 2 to the top surface of the floor unit 11 (floor surface material 19a). Specifically, the height from the floor surface 2 to the top surface of the lowest step 18a, the height between the top surfaces of each step 18a, and the height from the top surface of the uppermost step 18a to the top surface of the floor unit 11 (floor surface material 19a) are set to be approximately equal. Furthermore, in this embodiment, the uppermost step 18a is used as a landing, so its depth dimension (dimension in the front-to-back direction) is set to be longer than that of the other steps 18a.

[0046] The stair section 18 is attached to the side plates 132 and 133 of the plate bodies 131 to 133 in the second leg unit 13, which are arranged along the direction of ascent and descent of the stair section 18. To explain in more detail, for example as shown in Figure 7, of the left and right side plates 18c in the staircase section 18, the left side plate 18c is provided spanning the first side plate 132 of the front second leg unit 13 and the first side plate 132 of the rear second leg unit 13, and is fixed to the right side of these first side plates 132, 132. The right side plate 18c is provided spanning the second side plate 133 of the front second leg unit 13 and the second side plate 133 of the rear second leg unit 13, and is fixed to the left side of these second side plates 133, 133. The multiple treads 18a in the staircase section 18 are spanned between the upper surface of the stepped left side plate 18c and the upper surface of the stepped right side plate 18c, and are fixed to the upper surface of each tread of the left and right side plates 18c with screws or the like. Furthermore, the multiple risers 18b in the staircase section 18 are also fixed to the left and right side panels 18c with screws or the like.

[0047] Here, the left and right side panels 18c of the staircase section 18 are fixed to the side panels 132 and 133 of the second leg unit 13 by screws B. Specifically, for example, if the first side panel 132 of the second leg unit 13 is a board material having a core material C such as a flush panel, the left side panel 18c is connected to the first side panel 132 by driving screws B from the right side of the left side panel 18c toward the core material C of the first side panel 132, as shown in Figure 8. Similarly, if the second side panel 133 of the second leg unit 13 is a board material having a core material C such as a flush panel, the right side panel 18c is connected to the second side panel 133 by driving screws B from the left side of the right side panel 18c toward the core material C of the second side panel 133.

[0048] Furthermore, the means of attaching the tread board 18a to the side plates 132 and 133 of the second leg unit 13 are not limited to using the side plate 18c. For example, an angle material fixed to the lower surface of the tread board 18a and the side plates 132 and 133 may be used, or a groove may be formed on the side of the side plates 132 and 133 on the stair section 18 side into which the end of the tread board 18a is fitted, and the tread board 18a may be fitted into the groove. In other words, the means of attaching the tread board 18a to the second leg unit 13 are not particularly limited. Similarly, the means of attaching the riser board 18b to the second leg unit 13 are not particularly limited.

[0049] Furthermore, the end of the staircase section 18 located on the upward side in the direction of ascent is attached to the back plate 131 of the plates 131 to 133 of the rear second leg unit 13, which is located on the upward side in the direction of ascent of the staircase section 18. To explain in more detail, for example as shown in Figure 4, the height dimension of the back plate 131 of the rear second leg unit 13 is set such that the upper end surface of the back plate 131 is in contact with the lower surface of the uppermost step 18a (the top step 18a) among the multiple step 18a. The top step 18a is fixed to the upper end of the back plate 131 of the rear second leg unit 13 with its rear end resting on the back plate 131. In addition, a decorative panel 19d is placed on the upper end surface of the back plate 131 along with the rear end of the top step 18a. This decorative panel 19d connects the floor unit 11 and the second side plate 133 of the rear second leg unit 13, for example as shown in Figures 2 and 7. By providing the decorative panel 19d, the sense of unity between the floor unit 11, the stair section 18 and the second leg unit 13 can be enhanced, resulting in a better appearance. Furthermore, by providing the decorative panel 19d, the effect of suppressing the wobbling of the unit furniture 10 can also be obtained.

[0050] Furthermore, the attachment of the uppermost step 18a to the rear second leg unit 13 is not limited to the method of placing the uppermost step 18a on the back plate 131. For example, the height dimension of the back plate 131 may be set such that the upper end surface of the back plate 131 is substantially flush with the upper surface of the uppermost step 18a, or to a dimension where it is located above the upper surface of the uppermost step 18a, and an angle member may be used to fix the lower surface of the uppermost step 18a to the back plate 131. Alternatively, a groove may be formed on the side of the back plate 131 on the stair section 18 side into which the end of the uppermost step 18a is fitted, and the step 18a may be fitted into the groove. In other words, the means of attaching the uppermost step 18a to the second leg unit 13 are not particularly limited. Furthermore, the back plate 131 of the front second leg unit 13 crosses the lower part of the stair section 18. That is, the height dimension of the back plate 131 of the front second leg unit 13 is set such that, for example, the front end of the upper surface of the back plate 131 is in contact with the inclined surface of the side plate 18c.

[0051] The side panels 132 and 133 of the front second leg unit 13, and the back panel 131 and side panels 132 and 133 of the rear second leg unit 13 are positioned along the edge of the entrance 20, and the stair section 18 is positioned in the entrance 20 and attached to these panels positioned along the edge of the entrance 20. The stair section 18 is sized so that it does not protrude from either the front or right end of the unit furniture 10. The staircase section 18 is in a non-fixed state of contact with the floor surface 2 of room 1, and is provided in a state where it is not in contact with the walls 3, 4, and 5 of room 1, or is in contact with them via a buffer material.

[0052] The upper surface of the floor unit 11 is provided with flooring material 19a, such as flooring material or a mat. Furthermore, a ceiling material 19b is positioned between the left top panel 14 and the right top panel 14. This ceiling material 19b is a decorative panel with the same thickness as the top panels 14 and is fixed to the underside of the second building floor panel 11b. Furthermore, a skirting board 19c is provided on the front end face of the floor unit 11. This skirting board 19c covers the front end faces of the floor unit 11, the top plate 14, and the ceiling material 19b. The skirting board 19c is also provided on the entrance / exit 20 (the right end face of the floor unit 11).

[0053] The modular furniture unit 10 is installed on the floor surface 2 of room 1. The dimensions of the modular furniture unit 10 in the left-right direction are slightly shorter than the distance between the left wall surface 3 and the right wall surface 4, and it is in contact with the floor surface 2 and walls 3, 4, and 5 of room 1 in an unfixed state. In other words, the modular furniture unit 10 is not fixed to the building structure, but it is installed in a way that it fits snugly into a corner of room 1. In this configuration, a vibration-dampening means is interposed between the unit furniture 10 and the floor surface 2 and wall surfaces 3, 4, and 5 of room 1. This means is made of a vibration-dampening resin (foamed resin material) such as urethane foam, or EPDM (Ethylene Propylene Diene Monomer), which is ethylene propylene rubber. This means that vibrations are not transmitted between the unit furniture 10 and the building structure, and construction errors are not absorbed.

[0054] The assembly of the unit furniture 10 is carried out on-site at the discretion of the workers, so a detailed explanation will be omitted, but basically, it is assembled sequentially from the bottom up, similar to the structural framework of a normal building. Specifically, the leg units 12 and 13 are first assembled and installed. Next, the connecting plates 15 and 16 are installed, and the top plate 14 is provided on the upper end surfaces of the leg units 12 and 13. Then, the building floor panels 11a and 11b are provided on the upper surface of the top plate 14 to form the floor unit 11. Next, the floor surface material 19a is provided on the upper surface of the floor unit 11, and the handrail unit 17 is provided at the front end of the upper surface, and the step material (not shown) is provided at the right end of the upper surface. Next, the ceiling material 19b is provided in the center of the lower surface of the floor unit 11, and the skirting boards 19c are provided on the front and right end surfaces of the floor unit 11, and then the stair section 18 is assembled and provided. This completes the unit furniture 10.

[0055] The building panels (each building floor panel) that make up the floor unit 11 are manufactured in advance at a factory and delivered to the site. Pre-manufacturing at the factory has the advantage of making them easy to transport and allowing for immediate assembly at the site without any further processing.

[0056] While the modular furniture 10 is configured as described above, it is not limited thereto and can be modified as appropriate without departing from the spirit of the present invention. Similarly, the room 1 in which the modular furniture 10 is installed is not limited to the configuration described above and can be modified as appropriate without departing from the spirit of the present invention.

[0057] This embodiment provides the following excellent effects. In other words, the leg unit (second leg unit 13) to which the stair section 18 is attached has a plurality of vertical plates (back plate 131, side plates 132, 133) arranged perpendicular to the floor 2, and the stair section 18 is attached to the vertical plates (side plates 132, 133) among the plurality of vertical plates 131, 132, 133 that are arranged in line with the direction of ascent and descent of the stair section 18 in a plan view. Therefore, the vertical plates 132, 133 can be used as part of the stair section 18, and the stair section 18 can be built into the unit furniture 10. As a result, there is no need to unitize the stair section 18, so the number of parts that make up the stair section 18 can be reduced as much as possible, and the assembly of the stair section 18 can be made easy.

[0058] Furthermore, the second leg unit 13 to which the stair section 18 is attached has a first vertical plate (side plate 132, 133) arranged along the ascending direction of the stair section 18, and a second vertical plate (back plate 131) that is perpendicular to the first vertical plate 132, 133 in a plan view. The second vertical plate 131 is located on the ascending side of the stair section 18, and the end of the stair section 18 located on the ascending side is attached to the second vertical plate 131. Therefore, the mutually perpendicular first vertical plate 132, 133 and the second vertical plate 131 can be used as part of the stair section 18, and the stair section 18 can be built into the unit furniture 10. As a result, there is no need to unitize the stair section 18, so the number of parts that make up the stair section 18 can be reduced as much as possible, and the assembly of the stair section 18 can be made easy.

[0059] Furthermore, the first vertical panels 132, 133 and the second vertical panel 131 to which the staircase section 18 is attached are positioned along the edge of the entrance 20. Since the staircase section 18 is positioned in the entrance 20 and attached to the first vertical panels 132, 133 and the second vertical panel 131 positioned along the edge of the entrance 20, the staircase section 18 can be contained within the entrance 20 and will not protrude outward from the side edge of the floor unit 11 in a plan view. This makes the unit furniture 10 more compact.

[0060] Furthermore, since the unit furniture 10 is equipped with a first connecting plate 15 that connects leg units (first leg units 12, 12) that are spaced apart in the first direction (front-to-back direction) and a second connecting plate 16 that connects leg units (first leg unit 12 and second leg unit 13) that are spaced apart in the second direction (left-to-right direction) perpendicular to the first direction, horizontal wobbling of the unit furniture 10 can be suppressed. In particular, the unit furniture 10 of this embodiment allows the upper space 10b to be used like a loft, and because of its long height, it is prone to wobbling horizontally, but since the connecting plates 15 and 16 are provided to suppress wobbling, it is possible to move and work comfortably on the floor unit 11 (upper space 10b).

[0061] Furthermore, since the first connecting plate 15 and the second connecting plate 16 can be used as a counter desk, the counter desk's top surface (i.e., the connecting plates 15 and 16) can suppress wobbling of the unit furniture 10. Therefore, it is possible to suppress wobbling without providing dedicated components (dedicated components for suppressing wobbling) between the leg units 12, 12 which are spaced apart in the first direction, or between the leg units 12, 13 which are spaced apart in the second direction, thus minimizing the number of parts in the unit furniture 10. Furthermore, since the top surface of the first connecting plate 15 and the top surface of the second connecting plate 16 are set at the same height, the counter desk is easy to use, the work efficiency when working between the first connecting plate 15 and the second connecting plate 16 is improved, and it also looks good. Furthermore, the first connecting plate 15 and the second connecting plate 16 can also be used as shelves, and since the top surface of the first connecting plate 15 and the top surface of the second connecting plate 16 are set at the same height, they are easy to use and make it easy to move items between the first connecting plate 15 and the second connecting plate 16.

[0062] Furthermore, since the at least two leg units (second leg units 13, 13) to which the stair section 18 is attached are connected by stringers (side plates 18c) in the stair section 18, the wobbling of the unit furniture 10 can be suppressed by the members (stringers 18c) that make up the stair section 18. Therefore, it is possible to suppress wobbling without providing a dedicated member (a dedicated member for suppressing wobbling) between the at least two leg units 13 to which the stair section 18 is attached, and thus the number of parts of the unit furniture 10 can be reduced as much as possible.
