[0003] [Patent Document 1] JP 2014-195486 A Summary of the Invention [Problem to be solved by the invention]

[0004] In modular furniture, the lower and upper spaces of the floor unit (the ceiling unit in the case of Patent Document 1) are accessible to people. Therefore, if the furniture is placed in a room where people can see it, such as a living room, privacy may be difficult to ensure. In addition, since modular furniture allows people to enter and live in the lower and upper spaces, ease of use is also required.

[0005] The present invention has been made in view of the above circumstances, and an object of the present invention is to ensure privacy when using modular furniture and to improve ease of use. [Means for solving the problem]

[0018] Claim1 The invention described in the above relates to a room 1 structure in which a room space RS is formed by including a floor 2, walls 3, 4, 5, and a ceiling 6, and a unit furniture 10 is placed on the floor 2, as shown in, for example, FIG. 21 to FIG. 23. The unit furniture 10 includes a floor unit 11 arranged above a part of the floor 2, and a plurality of leg units 12, 13 supporting the floor unit 11. A lower space 10a is formed between the floor unit 11 and the floor 2, and an upper space 10b is formed between the floor unit 11 and the ceiling 6. A staircase 50 having a staircase 51 with a landing 52 connecting the floor having the room space RS to the floor above is disposed adjacent to the room space RS. The unit furniture 10 is disposed adjacent to the landing 52 of the staircase 51 via a partition wall 53, The partition wall 53 is An entrance opening 54 formed facing the landing 52 and communicating the upper space 10b of the unit furniture 10 with the stairwell 50; The container is characterized by comprising a closing member 55 that closes the entrance / exit opening 54 and is detachable from the partition wall 53.

[0038] Hereinafter, the 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 carrying out 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.

[0039] In Fig. 2, reference numeral 1 denotes a room. This room 1 is disposed inside a building such as a house, and at least comprises a floor surface 2 (floor 2) and a pair of opposing wall surfaces 3, 4 (walls 3, 4). In this embodiment, the room 1 also comprises another wall surface 5 (wall 5) perpendicular to the pair of wall surfaces 3, 4, and a ceiling 6. The space surrounded by the floor 2, the walls 3, 4 (5), and the ceiling 6 is the room space RS of the room 1. A unit piece of furniture 10 as shown in FIG. 1 is placed on a floor 2 of such a room 1.

[0040] Of the pair of walls 3, 4, one wall 3 is located on the left side when the unit furniture 10 is viewed from the front (front side), and the other wall 4 is located on the right side. The other wall 5 is located on the rear side (back side) of the unit furniture 10. Therefore, in the following description, the wall 3 located on the left side will be referred to as the left wall 3, the wall 4 located on the right side will be referred to as the right wall 4, and the other wall 5 located on the rear side will be referred to as the rear wall 5.

[0041] Each of the walls 3, 4, 5 is previously finished with wall covering (not shown), baseboard 40, molding (not shown), etc., and the floor 2 is previously finished with flooring material, matting, etc. The unit furniture 10 is to be placed and installed in the room 1 having such wall surfaces 3, 4, 5 and floor 2. Therefore, when installing the unit furniture 10 in the room 1, it is necessary to perform the work in a manner that does not damage these finishes.

[0042] The unit furniture 10 is a free-standing piece of furniture that is placed in the room 1 and is not fixed to the building frame. In other words, the unit furniture 10 is not mechanically joined to the building frame (joined with fasteners such as screws, adhesives, various metal fittings, etc.) and is not built into the building frame. In short, although the unit furniture 10 is in contact with the floor and walls of the room 1, it is simply a piece of furniture that is placed in the room 1, and can be placed in rooms of various buildings, including so-called detached houses, collective housing such as condominiums and apartments, and commercial buildings such as offices and office buildings. Since the unit furniture 10 is not joined to the building frame, the structure of the building in which the unit furniture 10 is placed is not particularly limited. In other words, the building frame may be made of wood, steel frame, reinforced concrete, or steel reinforced concrete, and the classification of the construction method (frame construction, wall construction, rigid frame construction, etc.) is not particularly limited. In short, since there is no need to join the unit furniture 10 to the building frame, there is no need to consider compatibility when joining the unit furniture 10 to the building frame.

[0043] The modular furniture 10 itself is knockdown furniture that is assembled on-site, and the components that make up the furniture are joined together using appropriate fasteners such as screws, adhesives, various metal fittings, etc. Specifically, as shown in Figs. 1 to 15, the unit furniture 10 includes, as a basic configuration, a floor unit 11 and leg units 12, 13 (first leg unit 12, second leg unit 13) that support the floor unit 11. Spaces 10a, 10b are formed above and below the floor unit 11. In this embodiment, the lower space 10a is used as a low-ceiling storage space that can be used from inside the room 1, and the upper space 10b can be used as one room with a ceiling height sufficient for living. Depending on the height dimensions of the leg units 12, 13, the lower space 10a may be used as a low-ceiling storage space and the upper space 10b may be used as one room, or both the lower space 10a and the upper space 10b may be used as one room or a low-ceiling storage space. Moreover, the unit furniture 10 in this embodiment includes a tabletop 14, a handrail unit 15, and lifting means 16 in addition to the above basic configuration.

[0044] The floor unit 11 is made of a building structural frame and has a structural strength comparable to that of the frame of the building on which the unit furniture 10 is placed. Therefore, the floor unit 11 is capable of supporting not only people on its upper surface, but also heavy objects on its upper surface. The architectural structural frame of the floor unit 11 in this embodiment is made up of wooden architectural panels used in the so-called wooden panel adhesive construction method. A building panel is a structure in which vertical and horizontal frame members are assembled into a rectangular shape, and auxiliary beam members are assembled vertically and horizontally inside the rectangular frame to form a frame body, with a facing attached to either or both sides of the frame body, resulting in a hollow structure. Furthermore, the hollow part is usually filled with insulating material such as glass wool or rock wool.

[0045] The floor unit 11 is composed of a floor body (floor building panels 11a, 11b) and is provided above a portion of the floor surface 2, with a width dimension set to be slightly shorter than the distance between the left side wall surface 3 and the right side wall surface 4. A plurality of architectural floor panels 11a, 11b (hereinafter architectural floor panels 11a, 11b) are used and are provided at a predetermined height above a portion, not the entire, of the floor surface 2 of the room 1. In this embodiment, the plurality of architectural floor panels 11a, 11b are provided at a height position where the ceiling height of the lower space 10a is 0.8 to 1.4 meters. The ceiling height of 0.8m to 1.4m is a height range that ensures a minimum height where a person can enter the lower space 10a and work by bending over. However, it is not limited to this, and the ceiling height may be set arbitrarily. That is, the ceiling height of the lower space 10a may be set to a dimension that allows a person to walk and work in a standing position, and the ceiling height of the upper space 10b may be set to a dimension that allows a person to walk and work in a bending position, so that the upper space 10b can be used like a loft. Also, for example, if the room 1 has an atrium and the ceiling height of the room 1 is high, the ceiling heights of both the lower space 10a and the upper space 10b may be set to a dimension 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 dimension that allows a person to walk and work in a bending position. In short, since the unit furniture 10 is merely a piece of furniture, there is no particular restriction on the vertical height in the lower space 10a and the upper space 10b, and the height can be set arbitrarily. The architectural floor panels 11a, 11b are connected to each other using tools such as screws, bolts, nuts, etc., thereby forming the floor unit 11.

[0046] The first leg unit 12 has a back panel 121, left and right side panels 122, 123, a bottom panel 124, and a shelf panel 125, and can be used as storage furniture. The first leg units 12 are provided below the front end (front end) of the floor unit 11 in a state where two of them stand side by side. That is, the unit furniture 10 has a pair of first leg units 12, 12 lined up on the left and right. In the following description, of the left and right side panels 122, 123, the side panel 122 located on the inside (the center side of the unit furniture 10) is referred to as the inner side panel 122, and the side panel 123 located on the outside is referred to as the outer side panel 123. In this embodiment, the first leg unit 12 is set to a height dimension such that the ceiling height of the lower space 10a is 0.8 to 1.4 meters.

[0047] The plates 121 to 125 constituting 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, 123 are generally U-shaped in plan view. The bottom plate 124 and the back plate 121 and the side plates 122, 123 are connected in a state in which the lower surface of the bottom plate 124 and the lower end surfaces of the back plate 121 and the side plates 122, 123 are generally flush with each other. The shelf plate 125 and the back plate 121 are connected in a state in which the rear end surface of the shelf plate 125 and the front surface of the back plate 121 are in contact with each other. The shelf plate 125 and the side plates 122, 123 are connected in a state in which the left end surface and the right end surface of the shelf plate 125 and the opposing surfaces of the side plates 122, 123 (the surfaces of the side plates 122, 123 facing each other) are in contact with each other. The number of shelves 125 is not limited to one, but may be more than one. Also, the shelves 125 may be movable shelves. The boards 121 to 125 constituting the first leg unit 12 may be made of a board material such as MDF (medium density fiberboard, JISA5905) or particle board (JISA5908), or may be made of these board materials in a flush structure or solid core structure, and can be selected as appropriate.

[0048] The second leg unit 13 has a back panel 131 and left and right side panels 132, 133. The second leg units 13 are provided below the rear end (rear end) of the floor unit 11 in a state where the two second leg units 13 stand side by side. That is, the unit furniture 10 has a pair of second leg units 13, 13 arranged side by side. In the following description, of the left and right side panels 132, 133, the side panel 132 located on the inside (the center side of the unit furniture 10) is referred to as the inner side panel 132, and the side panel 133 located on the outside is referred to as the outer side panel 133. In this embodiment, the second leg unit 13 is set to a height dimension such that the ceiling height of the lower space 10a is 0.8 to 1.4 meters.

[0049] The plates 131 to 133 constituting the second leg unit 13 are connected using tools such as screws, bolts, nuts, etc., thereby constituting the second leg unit 13. The back plate 131 and the side plates 132, 133 are generally U-shaped in plan view. The boards 131-133 that constitute the second leg unit 13 may be made of board materials such as MDF or particle board, like the boards 121-125 that constitute the first leg unit 12, or may be made of these board materials in a flush structure or a solid core structure, etc., and can be selected as appropriate. In this embodiment, the second leg unit 13 is constructed with the minimum number of elements forming an approximately C-shape when viewed from above, but it may also be configured in the same manner as the first leg unit 12, including a bottom plate and a shelf plate.

[0050] As shown in FIG. 14, the unit furniture 10 has two tabletops 14, 14, and the first leg unit 12 on the left side of the pair of first leg units 12, 12 and the second leg unit 13 on the left side of the pair of second leg units 13, 13 share one tabletop 14 (the left tabletop 14). The first leg unit 12 on the right side of the pair of first leg units 12, 12 and the second leg unit 13 on the right side of the pair of second leg units 13, 13 share the other tabletop 14 (the right tabletop 14). That is, the length dimension (front-rear dimension) of the tabletop 14 is set to a dimension approximately equal to the depth dimension (front-rear dimension) of the floor unit 11, and the tabletop 14 is fixed between the upper end surface of the first leg unit 12 and the upper end surface of the second leg unit 13.

[0051] The central edge of the top plate 14, which is located on the central side of the top plate 14, protrudes toward the center. Specifically, the right edge of the left tabletop 14 protrudes rightward from the inner side plate 122 of the left first leg unit 12 and the inner side plate 132 of the left second leg unit 13. In other words, the left tabletop 14 protrudes to the right (toward the center of the unit furniture 10). In addition, the left edge of the right tabletop 14 protrudes leftward from the inner side plate 122 of the right first leg unit 12 and the inner side plate 132 of the right second leg unit 13. In other words, the right tabletop 14 protrudes to the left (toward the center of the unit furniture 10).

[0052] The top plate 14 is composed of a first decorative panel 141 and a second decorative panel 142 having higher strength than the first decorative panel 141, and the second decorative panel 142 is disposed on the inside (toward the center of the unit furniture 10) of the first decorative panel 141. In other words, the second decorative panel 142 having higher strength protrudes laterally from the inner side panels 122, 132 of the leg units 12, 13. The first decorative panel 141 may be, for example, a board material such as MDF or particle board, or may be made of these board materials in a flush structure or solid core structure, etc., and can be selected as appropriate. In addition, the second decorative panel 142 may be, for example, a board material such as MDF (JIS A5905) or particle board (JIS A5908), or may be made of these board materials in a flush structure or solid core structure, etc., and can be selected as appropriate. Furthermore, the first decorative panel 141 and the second decorative panel 142 may be made of plate materials having different strengths. In this case, the second decorative panel 142 is made of a plate material having a higher strength than the first decorative panel 141 .

[0053] The leg units 12, 13 and the top plate 14 (first decorative panel 141, second decorative panel 142) are joined together using tools such as screws, bolts, nuts, etc. For example, in this embodiment, the top plate 14 is fixed to the leg units 12, 13 by screws B. The floor unit 11 is placed on top of a pair of top plates 14, 14 arranged side by side. That is, the first leg unit 12, the second leg unit 13, and the top plate 14 that is stretched between the first leg unit 12 and the second leg unit 13 constitute a support unit U that supports the floor unit 11.

[0054] As shown in FIG. 10, the floor unit 11 has a pair of first architectural floor panels 11a, 11a aligned left and right, and a pair of second architectural floor panels 11b, 11b aligned front and rear between the pair of first architectural floor panels 11a, 11a. The first building floor panel 11a is fixed to the upper surface of the top plate 14 spanning between the first leg unit 12 and the second leg unit 13, with the auxiliary rail members 112 arranged in the front-to-rear direction. The second building floor panel 11b is fixed to span between the upper surface of one top plate 14 and the upper surface of the other top plate 14, with the auxiliary rail members 112 arranged in the left-to-right direction. More specifically, the left and right ends of the second building floor panel 11b are fixed to span the upper surfaces of the central edges of the left and right top plates 14, 14.

[0055] The top plates 14, 14 and the floor unit 11 are joined together using tools such as screws, bolts, nuts, etc. For example, in this embodiment, the floor units 11 (architectural floor panels 11a, 11b) are fixed to the top plate 14 with screws B. Specifically, as shown in FIG. 15, the top plate 14 and the first architectural floor panel 11a are connected by driving screws B (e.g., screws having a length of 75 mm) into the underside of the top plate 14 toward the frame members 110 (frame members 110 arranged in the front-to-rear direction) and auxiliary beam members 112 of the first architectural floor panel 11a. In addition, the top plate 14 and the second architectural floor panel 11b are connected by driving screws B (e.g., screws having a length of 75 mm) from the underside of the top plate 14 toward the frame members 110 (frame members 110 arranged in the left-right direction) and auxiliary rail members 112 of the second architectural floor panel 11b. Furthermore, screws B (for example, 150 mm long screws) are driven from the top surface of the second building floor panel 11b toward the inner side panels 122, 132 of the leg units 12, 13 to connect the second building floor panel 11b, the top panel 14, and the leg units 12, 13. In addition, the first architectural floor panel 11a and the second architectural floor panel 11b are connected by driving a screw B (for example, a 50 mm long screw) from the frame 110 (frame 110 arranged in the front-to-rear direction) of the second architectural floor panel 11b toward the frame 110 (frame 110 arranged in the front-to-rear direction) of the first architectural floor panel 11a. In addition, although not shown in the figure, the first architectural floor panel 11a and the leg units 12, 13 are connected by driving screws B (e.g., screws having a length of 150 mm) from the top surface of the first architectural floor panel 11a toward the outer side panels 123, 133 and back panels 121, 131 of the leg units 12, 13.

[0056] In this embodiment, the protruding length of the top plate 14 (the length in the left-right direction of the portion protruding laterally beyond the inner side plates 122, 132) is set to 25 mm to 30 mm. If the protruding length is shorter than 25 mm, the portion of the second building floor panel 11b that comes into contact with the top plate 14 will be narrowed (the engagement between the second building floor panel 11b and the top plate 14 will be weakened), making it impossible to obtain a sufficient fall-off prevention effect. Also, if the protruding length is longer than 30 mm, it will be difficult to drive the screws B from the frame 110 (frame 110 arranged in the front-rear direction) of the second building floor panel 11b toward the frame 110 (frame 110 arranged in the front-rear direction) of the first building floor panel 11a.

[0057] Thus, in this embodiment, the top plate 14 protrudes laterally further than the inner side plates 122, 132, so that the distance between the left leg units 12, 13 and the right leg units 12, 13 (i.e., the width dimension of the opening for entering and exiting the lower space 10a) is long enough to easily enter and exit the lower space 10a, while preventing the floor body (hereinafter referred to as the "central floor body") spanning between the left and right support units U from falling off. That is, in the unit furniture 10 of this embodiment, since the top plate 14 protrudes laterally beyond the inner side panels 122, 132 of the leg units 12, 13, for example, even without shortening the distance between the left and right leg units 12, 13 or preparing a central floor body that is long in the left-right direction, the area of ​​the central floor body that comes into contact with the top plate 14 becomes wider, and the central floor body is engaged with the top plate 14 to an extent that it will not fall off. Therefore, it is possible to prevent the central floor body (second architectural floor panel 11b) from falling off while ensuring an opening with a width dimension that makes it easy to enter and exit the lower space 10a. Furthermore, in this embodiment, as shown in Figure 15, the central floor body (second architectural floor panel 11b) is not only fixed to the top plate 14 with screws B, but also fixed to the inner side plates 122, 132 of the leg units 12, 13 with screws B, so that it is possible to reliably prevent the second architectural floor panel 11b from falling off.

[0058] In this embodiment, as shown in Fig. 15, the contact surface between the first architectural floor panel 11a and the second architectural floor panel 11b is located above the inner side plates 122, 132 (see the two-dot chain line in Fig. 15). In other words, since the contact ends (ends that come into contact with each other) of both the first architectural floor panel 11a and the second architectural floor panel 11b are supported by the side plates, distortion or bending of the top plate 14 can be prevented, and the stability of the floor unit 11 is improved.

[0059] In addition, in this embodiment, as shown in Figure 15, among the frame constituent members (frame members 110 and auxiliary rail members 112) of the second building floor panel 11b, not only the frame constituent members arranged in the front-to-rear direction but also the ends of the frame constituent members arranged in the left-to-right direction are placed on the top plate 14. Furthermore, in this embodiment, among the frame components (frame members 110 and auxiliary rail members 112) of the second building floor panel 11b, not only the frame components arranged in the front-to-rear direction but also the frame components arranged in the left-to-right direction are fixed to the top plate 14 using screws B. In addition, in the second building floor panel 11b, the frame component members arranged in the front-to-rear direction and the frame component members arranged in the left-to-right direction are preferably joined using adhesive in addition to using fasteners such as screws.

[0060] The handrail unit 15 is a desk-type unit that can be used as a desk by a person on the upper surface (upper space 10b) of the floor unit 11. In addition, the front side of the right part of the handrail unit 15 is a storage shelf with multiple shelves 156, and can be used as storage furniture by a person on the floor surface 2 (a person on the front side of the unit furniture 10). In the unit furniture 10 of this embodiment, the lifting means 16 is installed on the right side wall surface 4. Therefore, at the front end of the upper surface of the floor unit 11, a fixing metal fitting (not shown) for fixing the rise frame 19a and the lifting means 16 is provided on the right side, and a handrail unit 15 is provided on the other parts (center and left sides). The lifting means 16 may be installed on the left side wall 3 instead of the right side wall 4. In this case, at the front end of the upper surface of the floor unit 11, a fixing bracket (not shown) for fixing the rise frame 19a and the lifting means 16 is attached to the left side, and the handrail unit 15 is provided in the other parts (central and right side). In addition, the lifting means 16 may be installed in the center, in which case, at the front end of the top surface of the floor unit 11, fixing brackets (not shown) for fixing the rise frame 19a and the lifting means 16 to the center are attached, and handrail units 15, 15 are provided in the other parts (left and right parts). The floor unit 11 and the handrail unit 15 are joined together using tools such as screws, bolts, nuts, etc.

[0061] The handrail unit 15 has two back panels 151, two side panels 152, a partition panel 153 that separates the two side panels 152 into left and right, a top panel 154, an upright panel 155 that stands up from the front end surface of the top panel 154, two shelf panels 156, and a bottom panel 157. The left back panel 151 is provided between the front ends of the partition panel 153 and the left side panel 152, while the right back panel 151 is provided in a position that separates the partition panel 153 and the right side panel 152 into front and rear, and the shelf panel 156 and the bottom panel 157 are provided in the space in front of it. The number of shelves 156 is not limited to two, but may be one, or three or more. Also, the shelves 156 may be movable shelves. The plates 151 to 157 that make up the handrail unit 15 are connected using tools such as screws, bolts, nuts, etc., thereby forming the handrail unit 15.

[0062] In addition, the handrail unit 15 in this embodiment is a desk type as described above, but is not limited to this, and may be, for example, a storage furniture type handrail unit that can be used as storage furniture. Specifically, the handrail unit has two side panels, a partition panel that divides the two side panels into left and right, a top panel, multiple shelf panels, and a bottom panel. In other words, the handrail unit does not have a back panel, and the line of sight can be seen in the front and back directions. Alternatively, a handrail wall (see handrail unit 231 in FIG. 19) may simply be provided, or a fence-like handrail unit may be provided.

[0063] In this embodiment, the lifting means 16 is a ladder for climbing up to the upper surface of the floor unit 11. The lifting means 16 (ladder) is attached to the floor unit 11 in a detachable manner. Moreover, the lifting means 16 is in contact with the floor surface 2 of the room 1 in an unfixed state. On the other hand, the lifting means 16 is not in contact with the walls 3, 4, 5 of the room 1. In addition, even if the lifting means 16 is not a ladder but a staircase or a slope connecting the floor surface 2 of the room 1 and the upper surface of the unit furniture 10, it is installed in a state where it is in contact with the floor surface 2 of the room 1 in an unfixed state and is not in contact with each of the walls 3, 4, 5 of the room 1.

[0064] A floor surface material 17 such as a flooring material or a mat is provided on the upper surface of the floor unit 11. A front edge portion of the floor surface material 17 avoiding the handrail unit 15 is housed in a step material 19a. Additionally, a ceiling material 18 is disposed between the left top plate 14 and the right top plate 14. The ceiling material 18 is a decorative panel with the same thickness as the top plate 14, and is fixed to the underside of the second architectural floor panels 11b, 11b. Further, a front panel 19b is provided on the front end surface of the floor unit 11. The front panel 19b covers the front end surfaces of the floor unit 11, the top panel 14, and the ceiling material 18.

[0065] The unit furniture 10 is placed on the floor surface 2 of the room 1. The dimension of the unit furniture 10 in the left-right direction is slightly shorter than the distance between the left side wall surface 3 and the right side wall surface 4, and the unit furniture 10 is in contact with the floor surface 2 and the walls 3, 4, and 5 of the room 1 in an unfixed state. In other words, the unit furniture 10 is not fixed to the building structure, but is installed in contact with the building structure so as to fit snugly (settled) in a corner of the room 1. At this time, between the unit furniture 10 and the floor surface 2 and the walls 3, 4, and 5 of the room 1, there is a vibration suppressing means made of a vibration suppressing resin (foamable resin material) such as urethane foam or EPDM (Ethylene Propylene Diene Monomer), which is ethylene propylene rubber, and it is possible to suppress the transmission of vibration between the unit furniture 10 and the building structure and to absorb construction errors.

[0066] The assembly work of the modular furniture 10 is carried out on-site by workers at their discretion, so a detailed explanation will be omitted, but like a normal building structural frame, it is basically assembled from the bottom up. That is, first, the leg units 12, 13 are assembled and installed. Next, the top plate 14 is provided on the upper end surfaces of the leg units 12, 13 to form the support unit U. Next, the architectural floor panels 11a, 11b are provided on the upper surface of the top plate 14 to form the floor unit 11. Next, a floor surface material 17 is provided on the upper surface of the floor unit 11, and a handrail unit 15, a step material 19a, and a fixing metal fitting (not shown) for fixing the lifting means 16 are provided at the front end of the upper surface. Next, a ceiling material 18 is provided in the center of the lower surface of the floor unit 11, a fascia board 19b is provided on the front end surface of the floor unit 11, and finally the lifting means 16 is provided, thereby forming the unit furniture 10.

[0067] The architectural panels (each architectural floor panel) that make up the floor unit 11 are manufactured in advance at a factory and delivered to the site. If they are manufactured in advance at a factory, they are easy to transport, and have the advantage that they can be assembled immediately on site without any processing or the like.

[0068] 2, a movable storage wagon W is disposed between the first leg unit 12 on the left side and the right leg unit 12, i.e., at the opening for entering and exiting the lower space 10a. By disposing the storage wagon W at the opening, the inside of the lower space 10a can be hidden and the opening can be used as a storage space. In addition, since the storage wagon W is movable, it can be easily moved when entering and exiting the lower space 10a, making it easy to use.

[0069] The unit furniture 10 is configured as described above, but is not limited to this and can be modified as appropriate without departing from the spirit of the present invention. Similarly, the room 1 in which the unit furniture 10 is installed is not limited to the above configuration and can be modified as appropriate without departing from the spirit of the present invention. Below, we will explain the structure of the room 1 (room structure) and examples of the unit furniture 10. The following examples may be combined as much as possible. In addition, in each example, elements that are common to the above explanations are given the same reference numerals, and explanations are omitted or simplified.

[0070] [Configuration Example 1] FIG. 16 is a cross-sectional view showing an example of a room 1 in which a unit piece of furniture 10 is provided. The unit furniture 10 comprises a floor unit 11 placed above a portion of the floor 2, and a plurality of leg units 12, 13 supporting the floor unit 11, such that a lower space 10a is formed between the floor unit 11 and the floor 2, and an upper space 10b is formed between the floor unit 11 and the ceiling 6. In this configuration example, a plurality of casters CA are provided on the lower end surfaces of the plurality of leg units 12, 13, so that the unit furniture 10 can be moved.

[0071] A partition 200 is provided on the ceiling 6 to separate the upper space 10b from the room space RS. The partition body 200 is an expandable partition wall, and is configured to be expandable in a direction (from top to bottom) from the ceiling 6 to separate the upper space 10b and the room space RS. Conversely, when the partition body 200 is to be contracted, it is contracted in a direction from bottom to top. The width dimension of the partition wall which is the partition body 200 may be equal to the width dimension of the floor unit 11, or may be shorter than the width dimension of the floor unit 11 to form a space for movement between the room space RS and the upper space 10b while keeping the upper space 10b and the room space RS separated by the partition wall.

[0072] Partition body 200, which is an expandable partition wall, has a so-called nested structure and has a first wall 201 having a rectangular cylindrical shape that penetrates in the vertical direction, a second wall 202 having a rectangular cylindrical shape that penetrates in the vertical direction, a third wall 203 having a rectangular cylindrical shape that penetrates in the vertical direction, and a fourth wall 204.

[0073] The ceiling 6 is provided with a storage section 6a for storing the partition body 200. Specifically, it is a storage recess that opens toward the room space RS. The storage recess that is the storage section 6a may be configured, for example, as a box body with an open bottom, or may refer to a structure in which an opening is formed in the ceiling material of the ceiling 6 and the first wall 201 is supported by the internal structure of the ceiling 6 (beams, girders, rafters, rafter supports, etc.).

[0074] The first wall 201 is located at the uppermost position (first from the top) of the partition body 200, and is housed and fixed in the above-mentioned storage section 6a.

[0075] The second wall 202 is located second from the top of the partition body 200 in the expanded state, and is stored inside the first wall 201 when the partition body 200 is contracted, as shown in Fig. 16(b). In other words, the second wall 202 is connected to the first wall 201 in a state in which the second wall 202 is movable along the inside of the first wall 201.

[0076] The third wall 203 is located third from the top of the partition body 200 in the deployed state, and is stored inside the second wall 202 when the partition body 200 is in the contracted state. That is, the third wall 203 is connected to the second wall 202 in a state in which the third wall 203 is movable along the inside of the second wall 202.

[0077] The fourth wall 204 is located at the lowermost position of the partition body 200 in the deployed state, and is stored inside the third wall 203 when the partition body 200 is in the contracted state. In other words, the fourth wall 204 is connected to the third wall 203 in a state in which it can move along the inside of the third wall 203.

[0078] A hook portion 205 onto which a hook or the like, such as an eyebolt, can be hung is attached to the lower end of the fourth wall 204. This allows the partition body 200 to be deployed from above the floor unit 11 or above the floor 2, for example, by using a rod with a hook attached to its tip. That is, the hook at the tip of the rod is hooked onto the hook portion 205 and pulled downward. Instead of pulling the hook portion 205 with a rod with a hook, for example, a pulling string may be attached to the lower end of the fourth wall 204.

[0079] In addition, the walls 201 to 204 constituting the partition body 200, which is an expandable partition wall, are provided with stoppers (not shown) between the walls 201 to 204 in order to maintain the contracted state.

[0080] The unit furniture 10 installed in the room 1 having the above-mentioned structure is arranged along the unfolding direction of the partition body 200. That is, since the partition body 200 separates the upper space 10b and the room space RS as described above, if the unit furniture 10 is not arranged beyond the unfolding direction of the partition body 200, the partition body 200 will not function as a partition body. Therefore, the unit furniture 10 is arranged beyond the unfolding direction of the partition body 200.

[0081] The unit furniture 10 also includes an engaged portion 206 that engages with the end of the partition body 200 in the unfolding direction. The engaged portion 206 in this configuration example has a recessed groove that accommodates the lower end of the fourth wall 204 and the hook portion 205. As the engaged portion 206, for example, a member formed with a grooved cross section such as a runner material is used. The engaged portion 206 is attached to the front edge of the upper surface of the floor unit 11. In this configuration example, the side end of the partition body 200 in the unfolding direction engaging with the engaged portion 206 means that the lower end of the fourth wall 204 and the hook portion 205 are accommodated in the recessed groove of the engaged portion 206. However, this is not limited to this, and for example, the unit furniture 10 may be provided with a hook that can be hung on the hook portion 205.

[0082] The floor unit 11 is formed in a hollow shape, and the leg units 12 and 13 can also be formed in a U-shape or hollow shape by the plates 121-124, 131, and 133. Therefore, the power lines can be wired without being exposed to the outside. This allows electrical wiring to be performed by attaching outlets to the floor unit 11, leg units 12 and 13, and handrail unit 15 of the unit furniture 10. Although not shown in the figure, an outlet is provided at the tip end of the wiring and a plug is provided at the base end, and although the wiring between the outlet and plug is exposed, the wires in between are wired inside the floor unit 11 and leg units 12, 13 so as not to be seen from the outside. The plug is inserted into a room 1 side outlet provided on the floor 2, the walls 3, 4, 5, or the ceiling 6 to obtain power. The room 1 side outlet is installed above the floor unit 11 so that it can be used from the upper space 10b. However, when it is used from the lower space 10a, it is assumed that it is installed below the floor unit 11.

[0083] [Configuration Example 2] FIG. 17 is a cross-sectional view showing an example of a room 1 in which a unit piece of furniture 10 is provided. In this configuration example, a partition body 210 is provided on the ceiling 6 of the room 1 for separating the upper space 10b from the room space RS. The unit furniture 10 comprises a floor unit 11 placed above a portion of the floor 2, and a plurality of leg units 12, 13 supporting the floor unit 11, such that a lower space 10a is formed between the floor unit 11 and the floor 2, and an upper space 10b is formed between the floor unit 11 and the ceiling 6. In this configuration example, a handrail unit 15 is provided at the front end portion on the upper surface of the floor unit 11.

[0084] The ceiling 6 is provided with a partition 210 for separating the upper space 10b from the room space RS. The partition 210 is a membrane (sheet-like member, screen-like member), and in this configuration example, a roll screen 210R shown in FIG. 17(a) or a sound-absorbing curtain 210C with sound-absorbing function shown in FIG. 17(b) is used. The roll screen 210R and the sound absorbing curtain 210C can of course be used continuously as a partition, but because they can be deployed and contracted very easily, they can also be suitably used as a temporary partition. The roll screen 210R and the sound-absorbing curtain 210C may be used at the same time. In this case, the sound-absorbing performance that the roll screen 210R does not have can be complemented, and gaps that occur when only one of them is used can be blocked by the other partition.

[0085] (About roller blinds) The roller blind 210R includes a screen body 211, a weight bar 212 provided at the lower end (tip) of the screen body 211, and a winding section 213 attached to the ceiling 6 and capable of winding up the screen body 211. The width dimension of the roller blind 210R, which is the partition body 210, may be equal to the width dimension of the floor unit 11, or may be shorter than the width dimension of the floor unit 11, thereby forming a space for movement between the room space RS and the upper space 10b while keeping the upper space 10b and the room space RS separated by the roller blind 210R.

[0086] The winding unit 213 has a fixed part 213a that is fixed to the ceiling 6, a winding shaft 213b that is supported between the left and right ends of the fixed part 213a so as to be rotatable around an axis, and an operating part (not shown) for rotating the winding shaft 213b. An upper end (base end) of the screen main body 211 is engaged with the winding shaft 213b, and can be unfolded or wound up according to the rotation of the winding shaft 213b. Therefore, in this configuration example, the winding section 213 functions as a storage section for storing the screen main body 211. The operating unit may be of a chain type, a pull cord type, a one-touch type, or the like, and any of these may be used.

[0087] The roller blind 210R is configured so that the screen body 211 can be deployed in a direction (from top to bottom) that separates the upper space 10b and the room space RS from the ceiling 6. Conversely, when the roller blind 210R is to be contracted, the screen body 211 is configured to be rolled up in a direction from bottom to top.

[0088] The unit furniture 10 also includes an engaged portion 214 with which an end portion of the roll screen 210R, which is the partition body 210, in the unfolding direction, engages. More specifically, the engaged portion 214 in this configuration example is a crosspiece 214 attached to the upper end of the front end surface of the handrail unit 15, and has the same length and cross-sectional shape as the weight bar 212 of the roller blind 210R. The weight bar 212 engages with the crosspiece 214, which is the engaged portion 214. The engagement method may be, for example, by a magnet or a hook-and-loop fastener. In addition, in this configuration example, the crosspiece 214 is used as the engaged portion 214, but a hook or the like on which the weight bar 212 can be hung may also be used.

[0089] The roller blind 210R is configured so that the screen body 211 unfolds in a direction (from top to bottom) from the ceiling 6 to separate the upper space 10b and the room space RS, but is not limited to this. For example, the screen main body 211 may be configured to be deployed in a direction (from top to bottom) that separates the upper space 10b and the lower space 10a from the ceiling 6, and the room space RS. In other words, the screen main body 211 has a length that reaches the floor 2. Also, a configuration may be adopted in which a roller blind 210R is attached to an edge of the floor unit 11 of the unit furniture 10, and the screen body 211 is unfolded from the floor unit 11 toward the ceiling 6 to separate the upper space 10b from the room space RS. Alternatively, the screen body 211 may be unfolded from the floor unit 11 toward the floor 2 to separate the lower space 10a from the room space RS.

[0090] (About sound absorbing curtains) The sound-absorbing curtain 210C is made of a sound-absorbing material, and can improve the sound environment, and can be adjusted by opening and closing the sound-absorbing curtain 210C. As an example of how to use the sound-absorbing curtain 210C, for example, when the upper space 10b of the unit furniture 10 is used as a telework room, the sound-absorbing curtain 210C can be closed during a web conference or a phone call to absorb sound, thereby suppressing the transmission of sound between the upper space 10b and the room space RS, and improving the comfort of the sound environment. Therefore, as in the case of using the sound-absorbing curtain 210C in combination with the roll screen 210R described above, the sound-absorbing curtain 210C may be used at the same time as the partition body in the other configuration examples to complement the sound-absorbing performance. Such a sound absorbing curtain 210C is hung from a curtain rail (not shown) provided on a curtain box 215, and can be expanded and contracted along the length direction of the curtain box 215 and the curtain rail. The curtain box 215 is attached to the ceiling 6. Therefore, the sound absorbing curtain 210C is suspended downward from the ceiling 6. Moreover, the sound absorbing curtain 210C is disposed inside the handrail unit 15 (on the upper space 10b side). The curtain box 215 and the curtain rail are provided from the left wall 3 to the right wall 4, but may be set shorter than that, or may have a curved shape so that the sound-absorbing curtain 210C can be wrapped around multiple sides of the unit furniture 10.

[0091] The upper end of the sound absorbing curtain 210C is stored in an inverted concave cross-section curtain box 215. That is, in this configuration example, the curtain box 215 functions as a storage section for storing the sound absorbing curtain 210C.

[0092] In this configuration example, the sound absorbing curtain 210C is of a horizontal sliding type, but this is not limited to this, and a sound absorbing curtain 210C of a type that is pulled up and contracted may be used. In this case, the sound absorbing curtain 210C unfolds downward.

[0093] In this configuration example, the sound-absorbing curtain 210C has a vertical dimension from the curtain box 215 and curtain rail attached to the ceiling 6 to the floor unit 11 of the unit furniture 10. In other words, the sound-absorbing curtain 210C is configured to separate the upper space 10b and the room space RS. However, the present invention is not limited to this, and the sound-absorbing curtain 210C may have a vertical dimension from the curtain box 215 and curtain rail attached to the ceiling 6 to the floor 2. In other words, the sound-absorbing curtain 210C may be configured to separate the lower space 10a and the upper space 10b from the room space RS.

[0094] Furthermore, the sound absorbing curtain 210C may have its lower end engaged with the upper surface of the floor unit 11. That is, a hook-and-loop fastener may be attached to the lower end of the sound absorbing curtain 210C and the upper surface of the floor unit 11 to enable engagement. Alternatively, a magnetic sheet may be attached to the lower end of the sound absorbing curtain 210C and the upper surface of the floor unit 11 to enable engagement. In this case, a metal plate to which the magnetic sheet on the sound absorbing curtain 210C side is attached may be embedded in the upper surface of the floor unit 11. Moreover, similar engaging means may be provided between the side edges of the sound absorbing curtain 210C and the walls 3, 4, 5 as in the lower end.

[0095] The modular furniture 10 that is placed and installed in the room 1 having the above-mentioned structure is arranged along the extension direction of the partition body 210. That is, since the partition body 210 separates the upper space 10b (which may include the lower space 10a) from the room space RS as described above, if the unit furniture 10 is not arranged along the unfolding direction of the partition body 210, the partition body 210 will not function as a partition body. Therefore, the unit furniture 10 is arranged beyond the unfolding direction of the partition body 210.

[0096] [Configuration Example 3] FIG. 18 is a cross-sectional view showing an example of a room 1 in which a unit piece of furniture 10 is provided. In this configuration example, a partition body 210 is provided on the ceiling 6 of the room 1 for separating the upper space 10b from the room space RS. The unit furniture 10 comprises a floor unit 11 placed above a portion of the floor 2, and a plurality of leg units 12, 13 supporting the floor unit 11, such that a lower space 10a is formed between the floor unit 11 and the floor 2, and an upper space 10b is formed between the floor unit 11 and the ceiling 6.

[0097] The ceiling 6 is provided with a partition 220 for separating the upper space 10b from the room space RS. The partition body 220 is an interlocking single sliding door 220 in which a plurality of single sliding doors 221, 222, 223 are interlocked, and is configured to be deployable in a direction (from left to right or from right to left) that partitions the upper space 10b and the room space RS from the wall 3. When the partition body 220 is to be contracted, it is contracted in the opposite direction to the deployment direction.

[0098] The multiple single-side sliding hanging doors 221, 222, 223 each have multiple sliders (not shown) at the upper end, and these sliders are slidably engaged with the hanging rail 224, so that the multiple single-side sliding hanging doors 221, 222, 223 are suspended from the hanging rail 224. The hanging rail 224 is attached to the ceiling 6. Therefore, the interlocking single sliding hanging door 220 is in a state of being hung downward from the ceiling 6. In other words, since the interlocking single sliding hanging door 220 is hung in this manner, it can be said that it is in a state of being deployed downward.

[0099] The multiple single-side sliding hanging doors 221, 222, 223 include a first hanging door 221 on the leading end side (rightmost) in the deployment direction, a second hanging door 222 in the middle, and a third hanging door 223 on the base end side (leftmost) in the deployment direction. In the contracted state, these multiple single-side sliding hanging doors 221, 222, 223 overlap and face each other in the front-to-rear direction. Interlocking mechanisms (not shown) are provided between the first hanging door 221 and the second hanging door 222, and between the second hanging door 222 and the third hanging door 223, respectively. The first hanging door 221 is provided with finger hooks 221a on the front and back sides at the side end portions thereof.

[0100] When the interlocking single sliding door 220 is opened, the interlocking mechanism functions as follows. That is, when the first hanging door 221 is pulled in the unfolding direction (rightward) until the left end of the first hanging door 221 reaches the position of the right end of the second hanging door 222, and is further pulled in the unfolding direction, the second hanging door 222 also moves in the unfolding direction together with the first hanging door 221. Then, when the first hanging door 221 and the second hanging door 222 are pulled in the unfolding direction until the left end of the second hanging door 222 reaches the position of the right end of the third hanging door 223, and is further pulled in the unfolding direction, the third hanging door 223 also moves in the unfolding direction together with the first hanging door 221 and the second hanging door 222.

[0101] On the other hand, when the interlocking single sliding door 220 is contracted, the interlocking mechanism functions as follows. That is, when the first hanging door 221 is pulled in the contraction direction (leftward) until the left end of the first hanging door 221 reaches the position of the left end of the second hanging door 222, and is further pulled in the contraction direction, the second hanging door 222 also moves in the contraction direction together with the first hanging door 221. Then, the first hanging door 221 and the second hanging door 22 are pulled in the deployment direction until the left end of the second hanging door 222 reaches the position of the left end of the third hanging door 223, and is further pulled in the contraction direction, the third hanging door 223 also moves in the contraction direction together with the first hanging door 221 and the second hanging door 222.

[0102] When the interlocking single sliding door 220 is fully extended to separate the upper space 10b in the unit furniture 10 from the room space RS, the first hanging door 221 functions as a fixture that opens and closes the entrance between the upper space 10b and the room space RS. That is, the second hanging door 222 does not move from a state where it overlaps and faces the first hanging door 221 in the front-rear direction unless the first hanging door 221 is moved further to the left. In other words, the first hanging door 221 can slide left and right without moving the second hanging door 222 from a position where it is moved to the wall 4 side to a state where it overlaps and faces the second hanging door 222 in the front-rear direction. In other words, since only the first hanging door 221 can be moved, it can be used like a fixture.

[0103] The wall 3 is provided with a storage section 3a for storing the partition body 220. Specifically, the storage section 3a is a door pocket that opens toward the room space RS. The door pocket that is the storage section 3a may be formed, for example, by a box body with an open side. The hanging rail 224 is attached to extend from the ceiling 6 to the ceiling surface of the door pocket which is the storage section 3a. This allows the multiple single sliding hanging doors 221, 222, 223 to be pulled into and stored in the door pocket which is the storage section 3a.

[0104] The modular furniture 10 that is placed and installed in the room 1 having the above-mentioned structure is arranged along the extension direction of the partition body 220. That is, since the partition body 220 separates the upper space 10b and the room space RS as described above, if the unit furniture 10 is not arranged along the unfolding direction of the partition body 220, the partition body 220 will not function as a partition body. Therefore, the unit furniture 10 is arranged along the unfolding direction of the partition body 220.

[0105] [Configuration Example 4] FIG. 19 is a cross-sectional view showing an example of a room 1 in which a unit piece of furniture 10 is provided. In this configuration example, a partition body 230 is provided on the ceiling 6 of the room 1 for separating the upper space 10b from the room space RS. The unit furniture 10 comprises a floor unit 11 placed above a portion of the floor 2, and a plurality of leg units 12, 13 supporting the floor unit 11, such that a lower space 10a is formed between the floor unit 11 and the floor 2, and an upper space 10b is formed between the floor unit 11 and the ceiling 6. In this configuration example, a handrail unit 231 is provided at the front end of the upper surface of the floor unit 11. This handrail unit 231 is not used as a desk or shelf, but functions as a handrail wall. The width dimension of this handrail unit 231 is set shorter than the width dimension of the floor unit 11, so that people can pass by the side of the handrail unit 231 and move between the floor 2 of the room 1 and the floor unit 11.

[0106] In addition, openings 5a, 5b are formed in the wall 5 of the room 1, connecting the room space RS with the outside, and the unit furniture 10 is arranged so that at least one of the lower space 10a and the upper space 10b is adjacent to the openings 5a, 5b. In this configuration example, a ground-level window 5a, which is an opening 5a, is formed at the lower end of the wall 5, and the lower space 10a of the unit furniture 10 is adjacent to this ground-level window 5a. Also, a high window 5b, which is an opening, is formed at the upper end of the wall 5, and the upper space 10b of the unit furniture 10 is adjacent to this high window 5b.

[0107] In addition, the present invention is not limited to the above-mentioned ground-level windows 5a and clerestory windows 5b, and a skylight that communicates with the roof may be formed in the ceiling 6, and the upper space 10b of the unit furniture 10 may be disposed adjacent to this skylight. In addition, the lower space 10a and the upper space 10b in the unit furniture 10 may be disposed adjacent to a waist-high window or a bay window.

[0108] An opening 2a is formed in the floor 2. The opening 2a can be opened and closed by a lid member 2b, and when the lid member 2b is opened, a box-shaped underfloor storage section 2c that opens upward is provided. The lower space 10a of the unit furniture 10 is adjacent to the opening 2a of the floor 2.

[0109] The ceiling 6 is provided with a partition 230 for separating the upper space 10b from the room space RS. The partition 230 includes a vertical wall 232 provided on the ceiling 6 and a shield 233 provided at the lower end of the vertical wall 232 .

[0110] The vertical wall 232 is located above the handrail unit 15, and is provided across the left and right walls 3 and 4. Therefore, the width dimension of the vertical wall 232 is set to be longer than the width dimension of the handrail unit 231.

[0111] The shielding body 233 is provided in a state of being bridged between the upper end of the handrail unit 231 and the lower end of the vertical wall 232. The shielding body 233 is made of, for example, a plate material having translucency, but may be made of a plate material having no translucency. Also, it may be made of a transparent plate material. That is, the partition 230 in this configuration example is a composite partition wall made up of a handrail unit 231 on the unit furniture 10 side, a vertical wall 232 on the room 1 side, and a shielding body 233 provided between them.

[0112] In addition, the shielding body 233 is held between the handrail unit 231 and the vertical wall 232, with its lower end inserted into a lower rail 233a with a concave cross-section provided on the upper end surface of the handrail unit 231 and its upper end inserted into an upper rail 233b with a concave cross-section provided on the lower end surface of the vertical wall 232.

[0113] The lower rail 233a is provided on the upper end surface of the handrail unit 231, and therefore the length dimension is approximately equal to the width dimension of the handrail unit 231. In addition, in order to pass by the side of the handrail unit 231 between the floor 2 of the room 1 and the floor unit 11, an end cap (not shown) is provided at the end of the lower rail 233a to prevent the shielding body 233 from protruding. The length dimension of the upper rail 233b is set to be equal to that of the lower rail 233a, but may be set to be longer in accordance with the width dimension of the vertical wall 232. When set to be equal to that of the lower rail 233a, an end cap (not shown) is provided in the same manner as the lower rail 233a. Furthermore, the end caps are detachable from the lower rail 233a and the upper rail 233b, allowing the shield 233 to be removed at any time.

[0114] The lower rail 233a functions as an engaged portion with which the lower end portion of the shielding body 233 located at the lowermost position of the partition body 230 engages. In this configuration example, the deployment direction side end of the partition body 230 engaging with the engaged portion 233a means that the lower end of the shielding body 233 is housed in the recessed groove of the engaged portion 233a.

[0115] The unit furniture 10 that is placed and installed in the room 1 having the above-mentioned structure is arranged along the extension direction of the partition body 230 (the up-down direction and the left-right direction). That is, since the partition body 230 separates the upper space 10b and the room space RS as described above, if the unit furniture 10 is not arranged along the extension direction of the partition body 230, the partition body 230 will not function as a partition body. Therefore, the unit furniture 10 is arranged along the extension direction of the partition body 230.

[0116] [Configuration Example 5] FIG. 20 is a cross-sectional view showing an example of a room 1 in which a unit piece of furniture 10 is provided. In the room 1 in this configuration example, no partition is provided to separate the lower space 10a or the upper space 10b from the room space RS, and a partition 240 is provided for the unit furniture 10. The unit furniture 10 comprises a floor unit 11 that is placed above a portion of the floor 2, and a plurality of leg units 12, 13 that support the floor unit 11, and a lower space 10a is formed between the floor unit 11 and the floor 2, and an upper space 10b is formed between the floor unit 11 and the ceiling 6.

[0117] The partition body 240 includes a wall panel 241 and a pair of left and right support rails 242 that support the wall panel 241 so as to be movable along the length direction of the wall panel 241.

[0118] The wall panel 241 is the main body of the partition 240, and its width is set to be shorter than the width of the floor unit 11. Therefore, it is possible to pass by the side of the wall panel 241 between the floor 2 of the room 1 and the floor unit 11. Furthermore, the vertical dimension of the wall panel material 241 is formed to be longer (higher) than the vertical dimension of the unit furniture 10. Therefore, the partition range provided by the wall panel material 241 can be elongated in the vertical direction. However, this is not limiting, and the width dimension of the wall panel 241 may be the same as the width dimension of the floor unit 11. Furthermore, when the width dimension of the wall panel 241 is the same as the width dimension of the floor unit 11, it is preferable that the vertical dimension of the wall panel 241 is the same as or smaller than the vertical dimension of the unit furniture 10, taking into consideration movement between the floor 2 of the room 1 and the floor unit 11. The wall plate 241 has engagement protrusions 241 a on the left and right end faces thereof, which engage with slits in the support rails 242 .

[0119] The support rail 242 is fixed to the front end surface of the floor unit 11, and may also be fixed to the front surfaces of the leg units 12, 13 as necessary. Such a support rail 242 has a slit formed along the length direction, and this slit engages with an engaging protrusion 241a provided on the left and right end faces of the wall panel material 241. Therefore, the wall panel material 241 is movable along the slits of the pair of left and right support rails 242. In other words, the wall panel material 241 is deployable from the floor unit 11 toward both the floor 2 and the ceiling 6.

[0120] In addition, the pair of left and right support rails 242 are set to a length close to the length from the lower end to the upper end of the unit furniture 10. Therefore, the moving distance of the wall panel material 241 is also set to a length close to the length from the lower end to the upper end of the knitted furniture 10.

[0121] Furthermore, in this configuration example, by moving the wall panel material 241 along a pair of left and right support rails 242, it is possible to transition from a state in which it separates the lower space 10a of the unit furniture 10 from the room space RS to a state in which it separates the upper space 10b from the room space RS. Therefore, when the lower space 10a and the room space RS are separated, the upper space 10b and the room space RS are not separated. Also, when the upper space 10b and the room space RS are separated, the lower space 10a and the room space RS are not separated.

[0122] Although not shown, the unit furniture 10 further includes a stopper portion for fixing the position of the partition body 240. The stopper portion may be provided between the wall panel material 241 and the support rail 242, or may be provided between the wall panel material 241 and the floor unit 11 or the leg units 12, 13.

[0123] [Configuration Example 6] 21 to 23 are cross-sectional views showing a room 1 in which a unit furniture 10 is provided and a staircase 50. FIG. The stairwell 50 is disposed adjacent to the room space RS of the room 1 and is integrated with the room space RS. The stairwell 50 is also provided with a staircase 51 with a landing 52 that connects the floor having the room space RS with the floor above. The staircase 50 is formed in a position surrounded by a right wall 4, a rear wall 5, and a partition wall 53 arranged opposite the right wall 4 and perpendicular to the rear wall 5. The type of the stairs 51 is not particularly limited as long as it has a landing 52, but in this configuration example, it is a return staircase.

[0124] The unit furniture 10 is arranged adjacent to a landing 52 of the stairs 51 with a partition wall 53 interposed therebetween. Moreover, the unit furniture 10 is arranged close to the rear wall 5 and the partition wall 53 that constitute the staircase 50.

[0125] The partition wall 53 has an entrance opening 54 formed facing the landing 52 and connecting the upper space 10b of the unit furniture 10 with the staircase 50, and a closing member 55 that closes the entrance opening 54 and is detachable from the partition wall 53.

[0126] The entrance / exit opening 54 is set in the vertical dimension from the height position of the top surface of the landing 52 of the partition wall 53 to the ceiling 6, and its width dimension is set to be equal to the width dimension (front-to-back dimension) of the landing 52.

[0127] The blocking member 55 has a plurality of vertical lattice members 55a arranged side by side at intervals from each other, and upper and lower connecting members 55b that connect the upper ends and the lower ends of the plurality of vertical lattice members 55a to each other. The upper connecting member 55b is detachably fixed to the ceiling 6, and the lower connecting member 55b is fixed to the lower edge of the entrance opening 54 formed in the partition wall 53. The connecting members 55b are fixed, for example, by bolting to long nuts embedded in the ceiling 6 and the partition wall 53, or by fixing with removable screws. In other words, the blocking member 55 can be fixed by a dry method, making it easy to attach and detach. The strength of the blocking member 55 and the fixing strength of the blocking member 55 are set to maintain safety performance to prevent people from falling. That is, although the blocking member 55 is detachably attached to the partition wall 53, it cannot be easily removed while blocking the entrance / exit opening 54. Therefore, if the blocking member 55 is left attached to the partition wall 53, the entrance / exit opening 54 can be blocked, making it difficult for people or objects to fall through the entrance / exit opening 54. In this configuration example, the blocking member 55 has a plurality of vertical lattice members 55a and upper and lower connecting members 55b, but is not limited to this. In other words, as long as the access opening 54 can be blocked by the blocking member 55, appropriate modifications can be made without departing from the spirit of the present invention.

[0128] When the blocking member 55 is removed from the partition wall 53, the entrance opening 54 is opened, so that communication is established between the landing 52 and the upper space 10b of the unit furniture 10, enabling passage therebetween.

[0129] [Configuration Example 7] FIG. 24 is a cross-sectional view showing an example of a unit furniture 10 with casters. In the unit furniture 10 of this configuration example, the leg units 12 and 13 include a unit body, a caster CA, and a biasing means.

[0130] The unit body of the first leg unit 12 on the front side has at least a bottom plate 124, and side plates 122, 123 on both side ends of the bottom plate 124, the lower ends of which protrude below the bottom plate 124 and contact the upper surface of the floor 2, and in this configuration example also has a back plate 121. It may also have a top plate 14 (141, 142). The unit body of the second leg unit 13 on the rear side is configured similarly to the above-mentioned first leg unit 12. Therefore, in the following description, the first leg unit 12 on the front side will be described as an example, and a description of the second leg unit 13 on the rear side will be omitted.

[0131] A plurality of casters CA are provided on the lower end of the bottom plate 124 of the unit body of the first leg unit 12 and the second leg unit 13. This allows the first leg unit 12 and the second leg unit 13, and therefore the unit furniture 10, to be moved.

[0132] The biasing means, although not shown, can be provided between the unit body and the caster, for example a suspension device, to bias the unit body upward against the caster CA and to position the side panels 122, 123 of the unit body so as to form a gap between them and the upper surface of the floor 2.

[0133] The biasing force of the biasing means is set to be smaller than the load of the floor unit 11. In other words, by removing the floor unit 11 from the multiple leg units 12, 13, the side plates 122, 123 of the unit body are separated from the upper surface of the floor 2, and the multiple leg units 12, 13 can be moved by the casters CA. Conversely, when the floor unit 11 is placed on multiple leg units 12, 13, the biasing force of the biasing means is defeated by the load of the floor unit 11, and the side panels 122, 123 of the unit body contact the upper surface of the floor 2, making it possible to fix the positions of the first leg unit 12 and the second leg unit 13, and ultimately the unit furniture 10.

[0134] [Configuration Example 8] FIG. 25 is a cross-sectional view showing another example of the unit furniture 10 with casters. In the modular furniture 10 of this configuration example, the leg units 12 and 13 are provided with casters CA and height adjustment means 300. The height adjustment means 300 adjusts the height position of the lower ends of the leg units 12, 13 relative to the floor 2, and in this configuration example, a jack device 300 is used.

[0135] The jack device 300 is attached to the lower end surfaces of the leg units 12, 13, and the height positions of the lower ends of the leg units 12, 13 relative to the floor 2 can be adjusted by extending the jack device in the vertical direction. When the jack device 300 is contracted, a gap (not shown) can be formed between the lower end surface of the jack device 300 and the floor 2, which enables movement using the casters CA.

[0136] [Configuration Example 9] FIG. 26 is a cross-sectional view showing a unit furniture 10 equipped with height adjustment means. In the modular furniture 10 of this configuration example, the leg units 12 and 13 are provided with height adjustment means 301 and 302. The height adjustment means in this configuration example is for simply adjusting the height of the leg units 12, 13, and includes a jack device 301 and a height adjustment member 302.

[0137] (About the jack device) The jack device 301 serving as the height adjustment means 301 adjusts the height position of the lower ends of the leg units 12 and 13 relative to the floor 2 , and adjusts the height position of the floor unit 11 relative to the floor 2 . When this jack device 301 is employed, the leg units 12, 13 do not include the bottom plate 124, but are formed in a rectangular cylindrical shape including the side plates 122, 123, the back plate 121, and a front plate (not shown).

[0138] The jack device 301 is provided inside the rectangular cylindrical leg units 12, 13, and is located in a position that cannot be seen from the outside, allowing the height of the leg units 12, 13 to be adjusted. To explain in more detail, the upper and lower ends of the jack device 301 are integrally attached with buffer parts 301a that are inserted into the rectangular cylindrical leg units 12, 13.

[0139] The upper buffer portion 301a is attached integrally to the upper ends of the leg units 12 and 13 which are shaped like square tubes. Further, a base portion 301b having an area larger than that of the lower end surface of the lower buffer portion 301a is provided on the lower end surface of the lower buffer portion 301a.

[0140] That is, the jack device 301 has upper and lower buffer parts 301a and a core with a base part 301b on the lower end surface, and is inserted into the rectangular cylindrical leg units 12, 13. When the jack device 301 is extended or contracted inside the rectangular cylindrical leg units 12, 13, the leg units 12, 13 attached to the upper buffer part 301a move upward. Conversely, when the jack device 301 is contracted, the leg units 12, 13 attached to the upper buffer part 301a move downward.

[0141] (About height adjustment parts) The height adjustment member 302, which is the height adjustment means 302, is placed on the upper end surfaces of the leg units 12, 13, and by adjusting the height of the leg units 12, 13, the height position of the floor unit 11 relative to the leg units 12, 13 can be adjusted. The height adjustment member 302 in this configuration example is constructed from an architectural panel similar to the floor unit 11, but is not limited to this and may be any panel strong enough not to be crushed by the load of the floor unit 11 and anything placed on it. A plurality of such height adjustment members 302 may be arranged in a stacked manner.

[0142] [Configuration Example 10] FIG. 27 is a diagram showing the configuration of a floor unit 11 in which an entrance / exit 310 is formed. In the floor unit 11 in this configuration example, an access opening 310 that connects the lower space 10a and the upper space 10b is formed. As described above, the floor unit 11 in this configuration example has a pair of first architectural floor panels 11a, 11a aligned left and right, and a pair of second architectural floor panels 11b, 11b aligned front to back between the pair of first architectural floor panels 11a, 11a. The first architectural floor panel 11a and the second architectural floor panel 11b are constructed by fixing a surface material to the upper surface of a frame body formed by combining multiple frame members 110 and multiple auxiliary rail members 112, but when forming an access opening 310, the multiple frame members 110 and multiple auxiliary rail members 112 are appropriately combined as shown in Figure 27.

[0143] FIG. 28 is a cross-sectional view showing an example of a unit furniture 10 in which an entrance / exit opening 310 is formed. In the unit furniture 10 of this configuration example, the floor unit 11 comprises a cover member 311 that opens and closes the access opening 310, and a desk component 312 that is attached to the cover member 311 and is assembled together with the cover member 311 when the access opening 310 is opened to form a folding desk.

[0144] The cover member 311 is an upper cover (hatch) attached to the edge of the entrance 310 in a state in which one end of the cover member 311 is rotatable about a rotation shaft. The cover member 311 has an illumination unit 311a configured to illuminate the lower space 10a when the entrance 310 is closed, and to illuminate the upper space 10b when the folding desk is in an assembled state. The illumination unit 311a is embedded in the back surface (the lower surface when the entrance 310 is closed) of the cover member 311. The illumination unit 311a may be connected to the above-mentioned power line that is wired so as not to be exposed to the outside, or may be battery-powered.

[0145] The desk configuration part 312 is assembled with the cover member 311 to form a folding desk, and includes a top panel part 313 and legs 314. Furthermore, this desk constituent part 312 is stored in the entrance 310 so as to be located on the underside of the cover member 311 in a folded state. That is, the entrance 310 has a stepped edge as shown in the figure, with the cover member 311 stored in the upper step and the desk constituent part 312 stored in the lower step. A plurality of supporting angle members 310a are provided on the lower step, and the desk constituent part 312 can be stored by bridging between the plurality of supporting angle members 310a.

[0146] The top panel 313 constitutes the top panel of the folding desk, and in this configuration example, a translucent plate material or a plate material having a translucent portion is used. Therefore, even when the entrance 310 is closed by the cover member 311, the lower space 10a can be illuminated by the lighting unit 311a. When the folding desk is in an assembled state, the top panel 313 has a connection member 313a for connecting the top panel 313 to the rear surface of the lid member 311. The connection member 313a is, for example, a fastener that can be advanced and retreated so as to protrude from an end face of the top panel 313, but is not limited to this and can be changed as appropriate.

[0147] Legs 314 are rotatably attached to the underside of tabletop 313 via a rotating shaft. Legs 314 can be rotated downward to be used as legs of a folding desk. Legs 314 can be kept aligned with the underside of tabletop 313 when folded.

[0148] To assemble the folding desk, first, the cover member 311 is lifted to open the entrance 310, and the desk constituent part 312 is removed. Next, the legs 314 of the desk constituent part 312 are rotated so that they are perpendicular to the top plate part 313. Thereafter, the legs 314 are placed in the entrance 310, and the top plate part 313 and the cover member 311 are connected by the connecting member 313a. A user of the folding desk can sit on the floor unit 11 with his / her legs stretched out into the lower space 10a as if sitting in a sunken kotatsu (Japanese-style heated table), and use the folding desk. The lighting unit 311a can also be used as a desk lamp.

[0149] [Configuration Example 11] FIG. 29 is a perspective view showing an example of a unit furniture 10 in which an entrance / exit opening 320 is formed. In the floor unit 11 in this configuration example, an access opening 320 that connects the lower space 10a and the upper space 10b is formed. The access opening 320 in this configuration example is formed by cutting out the edge of the floor unit 11. More specifically, it can be formed by not using one of the pair of second architectural floor panels 11b, 11b arranged in front and behind, among the architectural floor panels 11a, 11b that constitute the floor unit 11.

[0150] A box-shaped staircase 321 is provided at the entrance 320, allowing movement between the floor 2 of the room 1 and the floor unit 11. In addition, the height of the upper end 321a of the staircase 321 that contacts the lower surface of the floor unit 11 is set short, taking into consideration the thickness dimension of the floor unit 11. In other words, the height of the upper end 321a plus the thickness of the floor unit 11 is set to be approximately equal to the height of the riser of one staircase step.

[0151] For example, if a partition (roller screen 210R in the illustrated example) is provided between the ceiling 6 and the edge of the floor unit 11, the partition may make it difficult to see the edge of the floor unit 11. Therefore, forming an entrance 320 as in this configuration example and using stairs 321 for access is preferable in terms of improving safety. In addition, a handrail unit may be provided on the edge of the entrance 320 to further improve safety.

[0152] [Configuration Example 12] FIG. 30 is a diagram showing a unit furniture 10 equipped with a leg unit 330 formed in a stepped shape. In the modular furniture 10 of this configuration example, one of the leg units 12, 13, and 330, the leg unit 330, is formed in a stepped shape that connects the floor 2 of the room 1 and the floor unit 11. When moving between the floor 2 of the room 1 and the floor unit 11, this stepped leg unit 330 is used.

[0153] The stepped leg unit 330 is formed in a box shape with a bottom plate, side plates, risers, step plates, top plate, etc., and is structured to be able to support the floor unit 11 in the same way as the other leg units 12, 13. Moreover, in consideration of the thickness dimension of the floor unit 11, the height of an upper end portion 330a of the leg unit 330 that comes into contact with the lower surface of the floor unit 11 is set to be short. The leg unit 330 may be configured without a back panel, and the inside may be used as a storage section that can be accessed from the lower space 10a side.

[0154] [Configuration Example 13] FIG. 31 is a cross-sectional view showing a state in which a plurality of unit furniture pieces 10, 340 are stacked. That is, a unit furniture 340 smaller than the unit furniture 10 is placed on the upper surface of the floor unit 11 of the unit furniture 10. Note that each part of the small unit furniture 340 is configured similarly to that of the unit furniture 10 below, although the parts are different in size.

[0155] The small modular furniture 340 comprises a floor unit 341 and a plurality of leg units 342 and 343. The space below the floor unit 341 is defined as a lower space 340a, and the space above the floor unit 341 is defined as an upper space 340b. The floor unit 341 is disposed above a part of the floor unit 11 of the lower unit furniture 10. In this configuration example, it is disposed at a position close to the rear wall 5. A plurality of leg units 342, 343 are installed on the floor unit 11 of the lower modular furniture 10 and support the floor unit 341.

[0156] The lower space 10a and the upper space 10b of the lower unit furniture 10 are integrated with the room space RS of the room 1, and the lower space 340a and the upper space 340b of the small unit furniture 340 are integrated with the upper space 10b of the lower unit furniture 10.

[0157] It is preferable that at least one of the leg units 342, 343 of the small unit furniture 340 is disposed above at least one of the leg units 12, 13 of the unit furniture 10 below. Also, the small modular furniture 340 may be configured to include one first leg unit 342 on the front side, one second leg unit 343, and a floor unit 341 supported by these.

[0158] [Configuration Example 14] Although not shown in the drawings, in addition to the configuration examples given above, various room structure patterns and unit furniture 10 patterns may be adopted. For example, multiple removable tension rods may be installed between the floor unit 11 of the unit furniture 10 and the ceiling 6, or between the left and right walls 3 and 4, and a partition made of a membrane or plate material may be installed between these tension rods. Furthermore, a wire net may be installed between these tension rods, and ornamental plants and various items may be hung on the wire net for decoration. Also, a shutter device having a simpler structure than that used outdoors may be provided on the ceiling 6 as a partition. Further, the floor unit 11 of the unit furniture 10 may be provided with a partition extending in a fan shape from the floor unit 11 toward the left and right walls 3, 4.

[0159] According to this embodiment including the above-described configuration examples, excellent effects are obtained as follows. That is, since the partition bodies 200, 210, 220, 230 for separating at least one of the lower space 10a and the upper space 10b from the room space RS are provided on at least one of the floor 2, walls 3, 4, 5, and ceiling 6 forming the room space RS, when at least one of the lower space 10a and the upper space 10b is in use, the space can be shielded from the room space RS by the partition bodies 200, 210, 220, 230. This makes it easy to ensure privacy even if the unit furniture 10 is installed in a room 1 where people can see it, such as a living room. Furthermore, by simply separating at least one of the lower space 10a and the upper space 10b from the room space RS using the partition bodies 200, 210, 220, and 230, at least one of the lower space 10a and the upper space 10b in the unit furniture 10 can be used temporarily or continuously as a room separated from the room space RS, making it easy to enter and live in the lower space 10a and the upper space 10b.

[0160] In addition, the partition bodies 200, 210, 220, 230 are configured to be deployable from at least one of the floor 2, the walls 3, 4, 5, and the ceiling 6 in a direction separating at least one of the lower space 10a and the upper space 10b from the room space RS, and therefore the partition bodies 200, 210, 220, 230 can reliably shield at least one of the lower space 10a and the upper space 10b from the room space RS.

[0161] In addition, storage sections 6a, 213, 215, 3a for storing the partition bodies 200, 210, 220 are provided in at least one of the floor 2, the walls 3, 4, 5, and the ceiling 6, so that when the lower space 10a and the upper space 10b are not in use, the partition bodies 200, 210, 220 can be stored in the storage sections 6a, 213, 215, 3a and do not interfere with the room space RS.

[0162] Furthermore, since the unit furniture 10 is arranged along the unfolding direction of the partition bodies 200, 210, 230, the partition bodies 200, 210, 230 can be arranged between the unit furniture 10 and at least one of the floor 2, the walls 3, 4, 5, and the ceiling 6, so that the partition bodies can reliably function as partition bodies. Furthermore, the unit furniture 10 is provided with engaging portions 206, 214, 233b with which the unfolding direction side ends of the partition bodies 200, 210, 230 engage. By engaging the unfolding direction side ends of the partition bodies 200, 210, 230 with the engaging portions 206, 214, 233b of the unit furniture 10, the partition bodies 200, 210, 230 can more easily and reliably shield at least one of the lower space 10a and the upper space 10b from the room space RS.

[0163] In addition, since the unit furniture 10 is provided with a partition body 240 for separating at least one of the lower space 10a and the upper space 10b from the room space RS, when at least one of the lower space 10a and the upper space 10b is in use, the at least one space can be shielded from the room space RS by the partition body 240. This makes it easy to ensure privacy even if the unit furniture 10 is installed in a room 1 where people can see, such as a living room. Furthermore, by simply separating at least one of the lower space 10a and the upper space 10b from the room space RS using the partition body 240, at least one of the lower space 10a and the upper space 10b in the unit furniture 10 can be used temporarily or continuously as a room separated from the room space RS, making it easy to enter and live in the lower space 10a and the upper space 10b.

[0164] In addition, the partition body 240 is configured to be deployable from the floor unit 11 toward at least one of the floor 2, the walls 3, 4, 5, and the ceiling 6, so that at least one of the lower space 10a and the upper space 10b can be reliably shielded from the room space RS by the partition body 240.

[0165] In addition, the unit furniture 10 is arranged adjacent to the landing 52 of the staircase 51 via a partition wall 53, and the partition wall 53 has an entrance opening 54 formed facing the landing 52 and communicating the upper space 10b of the unit furniture 10 with the staircase 50, and a blocking member 55 that blocks the entrance opening 54 and is detachable from the partition wall 53, so that if the blocking member 55 is left attached to the partition wall 53, it is easy to block the line of sight from the staircase 50 to the upper space 10b of the unit furniture 10, contributing to ensuring privacy. Moreover, if the blocking member 55 is left attached to the partition wall 53, the entrance opening 54 can be blocked, making it difficult for people or objects to fall through the entrance opening 54. Furthermore, the entrance opening 54 can be opened by removing the blocking member 55 from the partition wall 53. This allows the upper space 10b of the unit furniture 10 to be used from the stairwell 50, making it easy to use. The strength of the blocking member 55 and the fixing strength of the blocking member 55 are set to a level that maintains safety performance to prevent people from falling.

[0166] In addition, since the blocking member 55 has a plurality of vertical lattice members 55a arranged side by side at intervals, it is possible to pass a line of sight from the stairwell 50 to the upper space 10b of the unit furniture 10. This makes it easy to see the state of the upper space 10b of the unit furniture 10 from the stairwell 50.

[0167] In addition, openings 2a, 5a, 5b that connect the room space RS with the outside are formed in at least one of the floor 2, walls 3, 4, 5, and ceiling 6, and the unit furniture 10 is arranged such that at least one of the lower space 10a and upper space 10b is adjacent to the openings 2a, 5a, 5b. As a result, ventilation and lighting can be obtained through the openings 2a, 5a, 5b, movement to and from the outside can be achieved, and items can be moved, making the unit furniture 10 easy to use.

[0168] In addition, the leg units 12, 13 supporting the floor unit 11 comprise a unit body having at least a bottom plate 124 and side plates 122, 123 at both side ends of the bottom plate 124, with their lower ends protruding downwardly from the bottom plate 124 and contacting the upper surface of the floor 2, a caster CA provided at the lower end of the bottom plate 124 on the unit body, and a biasing means provided between the unit body and the caster CA for biasing the unit body upward relative to the caster CA and arranged to form a gap between the side plates 122, 123 of the unit body and the upper surface of the floor 2, and the biasing force of the biasing means is set to be smaller than the load of the floor unit 11, so that by removing the floor unit 11 from the multiple leg units 12, 13, the side plates 122, 123 of the unit body are separated from the upper surface of the floor 2, and the multiple leg units 12, 13 can be moved by the caster CA. Conversely, if the floor unit 11 is placed on the multiple leg units 12, 13, the side panels 122, 123 of the unit body are in contact with the upper surface of the floor 2, so that the multiple leg units 12, 13 can be prevented from moving by the casters CA. This makes it easy to change the position of the unit furniture 10, making it easy to use.

[0169] In addition, the leg units 12, 13 supporting the floor unit 11 are equipped with casters CA provided at the lower ends of the leg units 12, 13, and height adjustment means 300 for adjusting the height position of the lower ends of the leg units 12, 13 relative to the floor 2. Therefore, the position of the unit furniture 10 can be easily changed by the casters CA, and the height adjustment means 300 can easily adjust the height of the floor unit 11 in the unit furniture 10, making it easy to use.

[0170] In addition, the floor unit 11, which is supported by a plurality of leg units 12, 13 and positioned above a portion of the floor 2, is formed with access openings 310, 320 connecting the lower space 10a and the upper space 10b, so that it is easy to move between the lower space 10a and the upper space 10b without passing through the room space RS on the room 1 side, making it easy to use.

[0171] In addition, the floor unit 11 is equipped with a cover member 311 that opens and closes the access opening 310, and a desk component 312 that is attached to the cover member 311 and is assembled together with the cover member 311 when the access opening 310 is open to form a folding desk. Therefore, the access opening 310 can be closed with the cover member 311, and when the access opening 310 is open, a folding desk can be assembled using the cover member 311 and the desk component 312 and used on the floor unit 11, making it easy to use. Furthermore, the cover member 311 has an illumination section 311a configured to illuminate the lower space 10a when the entrance 310 is closed, and to illuminate the upper space 10b when the folding desk is in an assembled state, so that the illumination section 311a can illuminate both the lower space 10a and the upper space 10b, making it easy to use.

[0172] Furthermore, among the multiple leg units 12, 13, 330 supporting the floor unit 11, one of the leg units 330 is formed in a stepped shape connecting the floor 2 of the room 1 and the floor unit 11, so that it is easy to move between the floor 2 of the room 1 and the floor unit 11 via the stepped leg unit 330, making it easy to use.

[0173] In addition, the unit furniture 10 further includes a handrail unit 15, 231 provided on the edge at the upper end of the floor unit 11, thereby preventing items and the like from falling from the floor unit 11 of the unit furniture 10 onto the floor 2 of the room 1, thereby contributing to improved safety.
