Modes for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, although various technically preferable limitations are imposed on the embodiments described below for carrying out the present invention, the technical scope of the present invention is not limited to the following embodiments and illustrated examples. Note that the directions in the following embodiments and illustrated examples are set only for convenience of explanation.

[0019] In FIG. 2, reference numeral 1 indicates a room. This room 1 is disposed inside a building such as a house, and includes a floor surface 2 (floor 2), a pair of wall surfaces 3 and 4 (wall 3, wall 4) facing each other, another wall surface 5 (wall 5) orthogonal to the pair of wall surfaces 3 and 4, and a ceiling 6. And the space surrounded by these floor 2, walls 3, 4, 5, and ceiling 6 is defined as the room space RS of the room 1. On the floor 2 of such a room 1, a unit furniture 10 as shown in FIG. 1 is placed and provided.

[0020] Of the pair of wall surfaces 3 and 4, one wall surface 3 is located on the left side when the unit furniture 10 is viewed from the front side (front side), and the other wall surface 4 is located on the right side. Also, the other wall surface 5 is located on the rear side (back side) of the unit furniture 10. Therefore, in the following description, the wall surface 3 located on the left side is referred to as the left side wall surface 3, the wall surface 4 located on the right side is referred to as the right side wall surface 4, and the other wall surface 5 located on the rear side is referred to as the rear side wall surface 5.

[0021] Note that each of the wall surfaces 3, 4, 5 is pre-finished with a wall cloth (not shown), a skirting board 7, a baseboard (not shown), etc., and the floor surface 2 is also pre-finished with a flooring material, a mat, etc. And the unit furniture 10 is placed and provided for the room 1 having such wall surfaces 3, 4, 5 and the floor surface 2. Therefore, when installing the unit furniture 10 in the room 1, it is necessary to perform the work so as not to damage such finishes.

[0022] The unit furniture 10 is furniture for placement that is installed in Room 1 and is not fixed to the building structure. That is, this unit furniture 10 is in a state where there is no mechanical connection (connection using fixtures such as screws, adhesives, various metal fittings, etc.) to the building structure and it is not built onto the building structure. In short, although the unit furniture 10 is in contact with the floor surface and wall surface of Room 1, it is simply furniture placed in Room 1 and can be arranged in rooms of various buildings including so-called detached houses, apartment buildings 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 structure, the structure of the building in which the unit furniture 10 is placed is not particularly limited. That is, the building structure may be wooden, steel frame, RC, or SRC, and the classification of its construction method (frame construction method, wall method, ramen method, etc.) is not particularly limited either. In short, since there is no need to join the unit furniture 10 and the building structure, there is no need to consider the compatibility when joining the unit furniture 10 and the building structure.

[0023] The unit furniture 10 itself is prefabricated furniture that is assembled on-site, and it is assumed that fixtures such as screws, adhesives, and various metal fittings are appropriately used for joining the members that make up the furniture. Specifically, as shown in FIGS. 1 to 6, the unit furniture 10 basically includes a floor unit 11, leg units 12 and 13 (first leg unit 12, second leg unit 13) that support the floor unit 11, and a staircase portion 16 that connects the floor surface 2 of the room 1 and the upper surface of the unit furniture 10. And spaces 10a and 10b are formed above and below with the floor unit 11 as a boundary. In the present embodiment, the lower space 10a is used as a low-ceiling storage space that can be used from within the room 1, and the upper space 10b can be used as a single room having a ceiling height sufficient for a living room. Also, depending on the height dimensions of the leg units 12 and 13, the lower space 10a may be used as a low-ceiling storage space and the upper space 10b may be used as a single room, or both the lower space 10a and the upper space 10b can be used as a single room or a low-ceiling storage space. In addition to the above basic configuration, the unit furniture 10 in the present embodiment further includes a top plate 14 and a handrail unit 15.

[0024] The floor unit 11 is composed of a building structural frame and has a structural strength comparable to that of the building frame on which the unit furniture 10 is installed. Therefore, not only can a person stand on the upper surface of the floor unit 11, but heavy objects can also be placed on the upper surface. The building structural frame of the floor unit 11 in the present embodiment is composed of wooden building panels used in the so-called wooden panel bonding method. A building panel is one in which vertical and horizontal framing members are assembled in a rectangular shape, auxiliary cross members are assembled vertically and horizontally inside the rectangular frame to form a frame body, and a face material is attached to both or one side of this frame body, having an internal hollow structure. Further, usually, heat insulating materials such as glass wool and rock wool are filled in the internal hollow portion.

[0025] The floor unit 11 is composed of floor bodies (building panels 11a, 11b, 11c for the floor) and is provided above a part of the floor surface 2, and is set to have a width dimension slightly shorter than the interval between the left side wall surface 3 and the right side wall surface 4. A plurality of building panels 11a, 11b, 11c for beds (hereinafter referred to as building floor panels 11a, 11b, 11c) are used, and they are provided at a predetermined height above a part of the floor surface 2 of the room 1, rather than the entire floor surface. In the present embodiment, a plurality of building floor panels 11a, 11b, 11c are provided at a height position where the ceiling height of the lower space 10a is 0.8 to 1.4 meters. Note that the ceiling height of 0.8 m to 1.4 m is a height range for ensuring the minimum height at which a person can enter the lower space 10a and somehow perform work by bending their waist. However, it is not limited to this, and the ceiling height may be arbitrarily set according to the ceiling height of the room 1. 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 posture, 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 bent-waist state, so that the upper space 10b can be used like a loft. Also, for example, if there is a void in the room 1 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 dimensions that allow a person to walk and work in a standing posture. Conversely, the ceiling heights of both the lower space 10a and the upper space 10b may be set to dimensions that allow a person to walk and work in a bent-waist state. In short, since the unit furniture 10 is merely furniture, the vertical height in the lower space 10a and the upper space 10b is not particularly limited and can be arbitrarily set. The building floor panels 11a, 11b, 11c are connected to each other using tools such as screws, bolts, and nuts, thereby constituting the floor unit 11.

[0026] As shown in FIG. 6, the building floor panels 11a, 11b, 11c have different shapes and sizes, and the floor unit 11 is formed in a state where one corner of a rectangle is cut out as a whole. More specifically, the floor unit 11 is formed with its side ends cut out and is provided with a lifting port 20 that communicates the lower space 10a and the upper space 10b. Although the building floor panels 11a, 11b, and 11c have different shapes and sizes, as a basic configuration, they include a plurality of frame members 110, a plurality of auxiliary cross members 112, and a surface member 111 fixed to the upper surface of a frame formed by combining these frame members 110 and auxiliary cross members 112. The building floor panel 11a (the first building floor panel 11a) located on the left side is arranged such that the length direction of the auxiliary cross member 112 is aligned with the front-rear direction. The building floor panel 11b (the second building floor panel 11b) located in the center is arranged such that the length direction of the auxiliary cross member 112 is aligned with the left-right direction. Also, this central building floor panel 11b is set wider than the left and right building floor panels 11a and 11c, and the length in the front-rear direction is set equal to that of the building floor panel 11a on the left side. The building floor panel 11c (the third building floor panel 11c) located on the right side is arranged such that the length direction of the auxiliary cross member 112 is aligned with the front-rear direction. Also, this third building floor panel 11c is set narrower than the first and second building floor panels 11a and 11b, and the length in the front-rear direction is also set shorter than that of the first and second building floor panels 11a and 11b. As a result, a hatch 20 can be formed in the floor unit 11.

[0027] The first leg unit 12 is a leg unit among the plurality of leg units 12 and 13 that does not have a staircase portion 16 attached. In the present embodiment, it is provided at three of the four corners of the floor unit 11 to support the floor unit 11. Such a first leg unit 12 has at least a back plate 121 and left and right side plates 122, 123, and has a substantially U-shaped configuration in plan view. Among the first leg units 12 in the present embodiment, the first leg units 12 provided in a state of standing side by side below the rear end portion (rear surface side end portion) in the floor unit 11 are used in a substantially U-shaped state in plan view composed of the back plate 121 and the left and right side plates 122, 123. On the other hand, the first leg unit 12 provided below the front end portion (front surface side end portion) in the floor unit 11 has a bottom plate 124 and a shelf plate 125, and can be used as storage furniture. In the following description, among the left and right side plates 122, 123, the side plate 122 located on the inner side (the central side of the unit furniture 10) is referred to as the inner side plate 122, and the side plate 123 located on the outer side is referred to as the outer side plate 123. The ceiling height of the lower space 10a of the first leg unit 12 is set to a height dimension of 0.8 to 1.4 meters in the present embodiment.

[0028] The plates 121 to 125 constituting the first leg unit 12 are connected using tools such as screws, bolts, and nuts, thereby constituting the first leg unit 12. The back plate 121 and the side plates 122, 123 have a substantially U-shaped configuration in plan view. Further, the bottom plate 124 is connected to the back plate 121 and the side plates 122, 123 in a state where 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 substantially flush. Further, the shelf plate 125 and the back plate 121 are connected in a state where the rear end surface of the shelf plate 125 and the front surface of the back plate 121 are in contact. Further, the shelf plate 125 and the side plates 122, 123 are connected in a state where the left and right end surfaces 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. Note that the number of the shelf plates 125 is not limited to one, and a plurality of them may be provided. Further, the shelf plate 125 may be a movable shelf. The plates 121 to 125 constituting the first leg unit 12 may be board materials such as MDF (Medium Density Fiberboard, JIS A5905) or particle board (JIS A5908), or may be a flash structure or a solid core structure using these board materials, etc., and can be appropriately selected.

[0029] The second leg unit 13 is the leg unit to which the staircase portion 16 is attached among the plurality of leg units 12 and 13. In the present embodiment, it is provided at one of the four corners of the floor unit 11 and supports the floor unit 11. Such a second leg unit 13 has at least a first support plate 131 and a second support plate 132. These first support plate 131 and second support plate 132 are arranged orthogonal to each other in plan view, and thereby the second leg unit 13 has at least a portion substantially L-shaped in plan view. Note that the second leg unit 13 in the present embodiment further has a third support plate 133. The third support plate 133 is arranged orthogonal to the second support plate 132 in plan view and parallel to the first support plate 131. Also, this third support plate 133 is arranged from the right end portion toward the rear among the left and right end portions of the second support plate 132. On the other hand, the first support plate 131 is arranged from the left end portion of the second support plate 132 toward the front. That is, the second leg unit 13 in the present embodiment is formed in a crank shape in plan view. The height dimension of the ceiling of the lower space 10a of the second leg unit 13 is set to a height dimension of 0.8 to 1.4 meters in the present embodiment. That is, it is set to the same height dimension as the first leg unit 12.

[0030] Each support plate 131 to 133 constituting the second leg unit 13 is connected using tools such as screws, bolts and nuts, and thereby the second leg unit 13 is constituted. Each support plate 131-133 that constitutes the second leg unit 13 may be a board material such as MDF or particle board, similar to the boards 121-125 that constitute the first leg unit 12. Alternatively, it may be a flush structure or a solid core structure using these board materials, etc., and can be appropriately selected. Note that the second leg unit 13 in the present embodiment has at least a first support plate 131 and a second support plate 132, and thus is provided with at least a portion that is substantially L-shaped in plan view. However, instead of joining the side end portions of the first support plate 131 and the second support plate 132, it may be configured to join the central portion of the first support plate 131 and the side end portion of the second support plate 132 to provide a portion that is substantially T-shaped in plan view.

[0031] The unit furniture 10 includes a plurality of top plates 14, and the top plates 14 are shared by the leg units 12 and 13 arranged in the front-rear direction. In other words, the plurality of top plates 14 arranged on the left side are provided so as to span the upper end surfaces of the first leg units 12 arranged at intervals in the front-rear direction on the left side. The length dimension (front-rear dimension) of the top plate 14 arranged on the left side is set to be substantially equal to the depth dimension (front-rear dimension) of the floor unit 11. The plurality of top plates 14 arranged on the right side are provided so as to span the upper end surfaces of the first leg unit 12 and the second leg unit 13 arranged at intervals in the front-rear direction on the right side. Since the plurality of top plates 14 arranged on the right side are not provided at the lifting port 20, their shapes and sizes are different from those of the plurality of top plates 14 arranged on the left side accordingly.

[0032] And the central side edge portion of the top plate 14 located on the central side among the top plates 14 protrudes toward the central side. Specifically, the right edge portion of the top plate 14 on the left side protrudes to the right more than the inner side plate 122 of each first leg unit 12 on the left side. That is, the top plate 14 on the left side protrudes toward the right side (the central side of the unit furniture 10). Also, the left edge of the right top plate 14 protrudes leftward beyond the inner side plate 122 of the right first leg unit 12 and the first support plate 131 of the right second leg unit 13. That is, the right top plate 14 protrudes toward the left side (the central side of the unit furniture 10).

[0033] The top plate 14 is composed of a first decorative panel 141 and a second decorative panel 142 with higher strength than the first decorative panel 141, and the second decorative panel 142 is arranged closer to the inner side (the central side of the unit furniture 10) than the first decorative panel 141. That is, the second decorative panel 142 with higher strength protrudes laterally beyond 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 a flush structure or a solid core structure using these board materials, and can be appropriately selected. Also, the second decorative panel 142 may be, for example, a board material such as MDF (JISA5905) or particle board (JISA5908), or may be a flush structure or a solid core structure using these board materials, and can be appropriately selected. Furthermore, different strength board materials may be selected for the first decorative panel 141 and the second decorative panel 142. In that case, the second decorative panel 142 is made of a board material with higher strength than the first decorative panel 141.

[0034] The joining of the leg units 12, 13 and the top plate 14 (the first decorative panel 141, the second decorative panel 142) is performed using tools such as screws, bolts, and nuts. For example, in this embodiment, the top plate 14 is fixed to the leg units 12, 13 with screws B. The floor unit 11 is placed on the horizontally arranged top plates 14, 14. That is, the first building floor panel 11a is fixed to the upper surface of the top plate 14 spanned between the left first leg units 12. The third building floor panel 11c is fixed to the upper surface of the top plate 14 spanned between the right first leg unit 12 and the second leg unit 13. Further, the second building floor panel 11b is spanned and fixed between the upper surface of one top plate 14 and the upper surface of the other top plate 14. More specifically, the left and right ends of the second building floor panel 11b are spanned and fixed to the upper surfaces of the central side edges of the left and right top plates 14 (left and right second decorative panels 142).

[0035] The joining of the top plates 14, 14 and the floor unit 11 is performed using tools such as screws, bolts and nuts. For example, in the present embodiment, the floor unit 11 (building floor panels 11a, 11b, 11c) is fixed to the top plate 14 by screws B. In the present embodiment, since the top plate 14 protrudes more toward the center than the left and right leg units 12, 13, the distance between the left leg units 12, 12 and the right leg units 12, 13 (that is, the width dimension of the opening for entering and exiting the lower space 10a) ensures a length that is easy to enter and exit the lower space 10a, and it is possible to prevent the central second building floor panel 11b from falling off. Further, distortion and deflection of the top plate 14 can be prevented, and the stability of the floor unit 11 is improved.

[0036] The handrail unit 15 is a unit of a type that can be used as a desk by a person in the upper space 10b on the upper surface of the floor unit 11. Further, the front side of the right side portion of the handrail unit 15 is a storage shelf having a plurality of shelf boards 156, and a person on the floor surface 2 (a person on the front side of the unit furniture 10) can use it as storage furniture. In the unit furniture 10 of the present embodiment, an elevator opening 20 is formed on the right side of the front end portion of the floor unit 11 and a staircase portion 16 is provided. Therefore, at the front end portion of the upper surface of the floor unit 11, the staircase portion 16 is provided on the right side portion, and the handrail unit 15 is provided on the other portions (central portion and left side portion). Note that the location where the staircase section 16 is installed may be on the left side wall 3 instead of on the right side wall 4 side. In that case, the handrail unit 15 will be provided at the central part and the right side part of the upper surface of the floor unit 11. The joining of the floor unit 11 and the handrail unit 15 is carried out using tools such as screws, bolts and nuts.

[0037] The handrail unit 15 has two back plates 151, two side plates 152, a partition plate 153 that partitions the space between the two side plates 152 left and right, a top plate 154, a standing plate 155 that stands up from the front end surface of the top plate 154, two shelf plates 156, and a bottom plate 157. The left back plate 151 is provided between the front ends of the partition plate 153 and the left side plate 152, while the right back plate 151 is provided at a position that partitions the space between the partition plate 153 and the right side plate 152 front and back, and the shelf plate 156 and the bottom plate 157 are provided in the front space thereof. Note that the number of the shelf plates 156 is not limited to two, and may be one or three or more. Also, the shelf plate 156 may be a movable shelf. The plates 151 - 157 that constitute the handrail unit 15 are connected using tools such as screws, bolts and nuts, and thereby constitute the handrail unit 15.

[0038] Note that the handrail unit 15 in the present embodiment is configured as described above, but is not limited thereto. For example, a storage furniture - type handrail unit that can be used as storage furniture may also be used. Specifically, the handrail unit has two side plates, a partition plate that partitions the space between the two side plates left and right, a top plate, a plurality of shelf plates, and a bottom plate. That is, the handrail unit does not have a back plate and has a state where the line of sight passes through in the front - rear direction. In addition, simply a handrail wall (refer to the handrail unit 215 in FIGS. 7 - 9) may be provided, or a fence - shaped handrail unit may be provided.

[0039] The staircase portion 16 includes a plurality of tread plates 16a, a plurality of kick plates 16b, and side plates 16c, and is formed in a box shape. The side plates 16c are formed in a stepped shape in side view and constitute the outer side surface on the right side in the staircase portion 16. The height dimension of the staircase portion 16 is considered based on the height from the floor 2 to the upper surface of the floor unit 11 (floor covering 17). That is, it is set such that the height from the floor 2 to the upper surface of the lowermost tread plate 16a, the height between the upper surfaces of the respective tread plates 16a, and the height from the upper surface of the uppermost tread plate 16a to the upper surface of the floor unit 11 (floor covering 17) are substantially equal.

[0040] Such a staircase portion 16 is attached to the first support plate 131 arranged along the elevating direction of the staircase portion 16 among the respective support plates 131 to 133 in the second leg unit 13. More specifically, the plurality of tread plates 16a in the staircase portion 16 are provided so as to be bridged between the upper surface of the side plates 16c formed in a stepped shape and the first support plate 131. For the attachment of the tread plate 16a to the first support plate 131, for example, an angle member fixed to the lower surface of the tread plate 16a and the first support plate 131 may be used, or a concave groove portion into which the end portion of the tread plate 16a is fitted may be formed on the side surface of the staircase portion 16 in the first support plate 131, and it may be attached by fitting it into the concave groove portion. That is, the means for attaching the tread plate 16a to the first support plate 131 is not particularly limited.

[0041] Also, the staircase portion 16 has an end portion located on the ascending side in the elevating direction attached to the second support plate 132 located on the ascending side in the elevating direction of the staircase portion 16 among the respective support plates 131 to 133 in the second leg unit 13. More specifically, the end portion (rear end portion) on the side of the second support plate 132 of the step plate 16a located at the uppermost position among the plurality of step plates 16a is attached to the second support plate 132. The attachment of the uppermost step plate 16a to the second support plate 132 may use, for example, the lower surface of the uppermost step plate 16a and an angle member fixed to the second support plate 132, or a concave groove portion into which the end portion of the uppermost step plate 16a is fitted may be formed on the side surface of the step portion 16 of the second support plate 132 and the step plate 16a may be fitted and attached to the concave groove portion. That is, the attachment means of the uppermost step plate 16a to the second support plate 132 is not particularly limited.

[0042] The first support plate 131 and the second support plate 132 are arranged along the edge of the lifting port 20, the step portion 16 is arranged in the lifting port 20, and is attached to the first support plate 131 and the second support plate 132 arranged along the edge of the lifting port 20. And the step portion 16 is sized so as not to protrude from the front end portion or the right end portion of the unit furniture 10. In addition, since the third support plate 133 is arranged to extend rearward from the lifting port 20, in this embodiment, the step portion 16 is not attached to the third support plate 133, but the side plate 16c of the step portion 16 may be attached to the third support plate 133. In this embodiment, a plurality of step plates 16a are assumed to be attached to the first support plate 131, but a plurality of kick-in plates 16b may also be attached to the first support plate 131 together by attachment means such as an angle member. In addition, the surfaces of the first support plate 131 and the second support plate 132 on the side of the step portion 16 are flush with the surface of the curtain plate 19 described later. Also, the step portion 16 is provided in a state of being in contact with the floor surface 2 of the room 1 in a non-fixed state and not in contact with or in contact with the buffer material between the wall surfaces 3, 4, 5 of the room 1.

[0043] On the upper surface of the bed unit 11, a floor covering material 17 such as a flooring material or a mat is provided. Also, between the left top plate 14 and the right top plate 14, a ceiling material 18 is arranged. The ceiling material 18 is a decorative panel having the same thickness as the top plate 14 and is fixed to the lower surface of the second building floor panel 11b. Also, a curtain board 19 is provided on the end face on the front end side of the bed unit 11. The curtain board 19 covers the front end faces of the bed unit 11, the top plate 14, and the ceiling material 18. Also, the curtain board 19 is provided at the lift opening 20 as well.

[0044] The unit furniture 10 is installed on the floor surface 2 of the room 1. The unit furniture 10 has a lateral dimension that is slightly shorter than the distance between the left wall surface 3 and the right wall surface 4, and is in non-fixed contact with the floor surface 2 and the wall surfaces 3, 4, 5 of the room 1. That is, the unit furniture 10 is not fixed to the building structure, but is provided in contact so as to fit (nest) perfectly into a corner of the room 1. At that time, between the unit furniture 10 and the floor surface 2 and the wall surfaces 3, 4, 5 of the room 1, vibration suppression means made of a resin capable of suppressing vibration (foam resin material) such as urethane foam or EPDM (Ethylene Propylene Diene Monomer) which is an ethylene propylene rubber is interposed, so that the transmission of vibration between the unit furniture 10 and the building structure can be suppressed and construction errors can be absorbed.

[0045] The assembly work of the unit furniture 10 is appropriately judged and advanced on-site by the worker, so a detailed explanation is omitted, but basically, like a normal building structural body, it is assembled sequentially from below. That is, first, the leg units 12 and 13 are assembled and installed. Subsequently, the top plate 14 is provided on the upper end surfaces of the leg units 12 and 13. Subsequently, the building floor panels 11a and 11b are provided on the upper surface of the top plate 14 to form the floor unit 11. Subsequently, the floor covering 17 is provided on the upper surface of the floor unit 11, and a handrail unit 15 and a rising frame member (not shown) are provided at the front end portion on the said upper surface. Subsequently, a ceiling member 18 is provided at the central portion of the lower surface of the floor unit 11, a curtain board 19 is provided on the front end surface of the floor unit 11, and subsequently, the staircase portion 16 is assembled and provided. The assembly of the staircase portion 16 is performed by attaching at least a plurality of treads 16a to the first support plate 131. Also, the topmost tread 16a is attached to the second support plate 132. In this embodiment, an angle member is used for attachment. Also, the plurality of treads 16a are fixed to the upper surfaces of the respective steps of the side plates 16c formed in a stepped shape by screws or the like. The plurality of kick plates 16b are also fixed to the side plates 16c formed in a stepped shape by screws or the like. Thereby, the unit furniture 10 is formed.

[0046] Note that the building panels (each building floor panel) constituting the floor unit 11 are manufactured in a factory in advance and delivered to the site. If they are manufactured in a factory in advance, there is an advantage that they are easy to transport and the assembly work can be carried out immediately without performing processing or the like at the site.

[0047] Also, in the example shown in FIG. 2, a movable storage wagon W is arranged at an opening for entering and exiting between the left first leg unit 12 and the right leg unit 12, that is, in the lower space 10a. By arranging the storage wagon W at the opening, the inside of the lower space 10a can be hidden from view, and the opening can be used as a storage space. Also, since the storage wagon W is movable, it can be easily moved when entering and exiting the lower space 10a, and it is convenient to use. Note that a storage wagon W for each family member may be prepared so that each person can use the storage wagon W.

[0048] The unit furniture 10 is configured as described above, but is not limited thereto, and can be appropriately changed 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 appropriately changed without departing from the spirit of the present invention.

[0049] According to the present embodiment, the following excellent effects are achieved. That is, the second leg unit 13 to which the staircase portion 16 is attached is composed of a plurality of support plates 131, 132, 133 that are adjacent to each other and arranged perpendicular to each other in plan view. The staircase portion 16 is attached to the first support plate 131 that is arranged along the ascending and descending direction of the staircase portion 16 in plan view among the plurality of support plates 131, 132, 133. Therefore, the first support plate 131 can be used as a part of the staircase portion 16, and the staircase portion 16 can be made to be in a state of being attached to the unit furniture 10. As a result, it is not necessary to unitize the staircase portion 16, so the number of parts constituting the staircase portion 16 can be reduced as much as possible, and the assembly of the staircase portion 16 can be easily performed.

[0050] Further, the second leg unit 13 has a first support plate 131 arranged along the ascending and descending direction of the staircase portion 16 and a second support plate 132 adjacent to the first support plate 131 and perpendicular to the first support plate 131 in plan view. The second support plate 132 is located on the ascending side in the ascending and descending direction of the staircase portion 16. Since the end portion of the staircase portion 16 located on the ascending side in the ascending and descending direction is attached to the second support plate 132, the mutually perpendicular first support plate 131 and second support plate 132 can be used as a part of the staircase portion 16, and the staircase portion 16 can be made to be in a state of being attached to the unit furniture 10. As a result, it is not necessary to unitize the staircase portion 16, so the number of parts constituting the staircase portion 16 can be reduced as much as possible, and the assembly of the staircase portion 16 can be easily performed.

[0051] Further, the first support plate 131 and the second support plate 132 of the second leg unit 13 to which the staircase portion 16 is attached are arranged along the edge of the 20 lifting opening, and the staircase portion 16 is the lifting opening20 is disposed at the 20 and is attached to the first support plate 131 and the second support plate 132 disposed along the edge of the hatchway, so that the staircase portion 16 can be stored in the hatchway 20 and can be prevented from protruding outward from the side end of the floor unit 11 in plan view. Thereby, the unit furniture 10 can be made more compact.

[0052] 〔Modification Example〕 Note that the embodiments to which the present invention is applicable are not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention. Hereinafter, modification examples will be described. The following modification examples may be combined as much as possible. Also, in each of the following modification examples, elements common to the above-described embodiments are denoted by common reference numerals, or reference numerals having the same last two digits, and the description thereof is omitted or simplified.

[0053] 〔Modification Example 1〕 The unit furniture 210 in FIG. 7 includes a floor unit 211, a first leg unit 212, a second leg unit 213, a handrail unit 215, and a staircase portion 216. And the floor 2 side of the floor unit 211 is a lower space 210a, and the ceiling 6 side of the floor unit 211 is an upper space 210b. The unit furniture 210 of this modification example is in a form in which a hatchway is not formed at the side end of the floor unit 211, and the floor unit 211 is used as a rectangular shape in plan view. Accordingly, the staircase portion 216 is disposed on one side surface of the unit furniture 210.

[0054] The first leg unit 212 is a leg unit to which the staircase portion 216 is not attached, and has at least a back plate, two side plates provided at both ends in the width direction of the back plate, and a partition plate that partitions between the two side plates in both width directions, and has a bottom plate and a shelf plate as necessary. And the first leg unit 212 is in a state where the opposite side of the back plate is open, and the open portion is disposed toward the center side of the lower space 210a. This first leg unit 212 supports the left end portion of the floor unit 211 from below.

[0055] The second leg unit 213 is a leg unit to which the staircase portion 216 is attached, and has at least a back plate, two side plates provided at both ends in the width direction of the back plate, and a partition plate that partitions both sides in the width direction between the two side plates. These back plate, side plates, and partition plate are a plurality of support plates. Further, the second leg unit 213 has a bottom plate and a shelf plate as necessary. And the second leg unit 213 is in a state where the opposite side of the back plate is open, and the open portion is arranged toward the center side of the lower space 210a. This second leg unit 213 supports the right end portion of the floor unit 211 from below. Further, in the second leg unit 213, the back plate is directed right outward, and the staircase portion 216 is attached to this back plate.

[0056] Since the floor unit 211 is rectangular in plan view, the staircase portion 216 can secure a lifting space having a length equal to the length of the right edge portion of the floor unit 211 in plan view. In other words, the lifting direction of the staircase portion 216 is aligned with the length direction of the right edge portion of the floor unit 211 in plan view. And this staircase portion 216 is attached to a support plate (back plate) arranged along the lifting direction of the staircase portion 216 in plan view.

[0057] A handrail unit 215 is provided at the front end portion of the floor unit 211 along the length direction of the front end portion. The handrail unit 215 in this modification is a handrail unit of a storage furniture type.

[0058] The unit furniture 210 configured as described above can use the lower space 210a and the upper space 210b for various purposes. In the table shown in FIG. 7, it is shown that the lower space 210a can be used as a closet or a workspace. Also, it is shown that the upper space 210b can be used as a bedroom, a cubby room, a loft storage, or a collection room. The usage example of the lower space 210a and the usage example of the upper space 210b can be appropriately combined.

[0059] When the lower space 210a is used as a closet, for example, a hanger pipe Hp is spanned and provided between the back plate of the first leg unit 212 and the back plate of the second leg unit 213. Thereby, the space on one side partitioned by the partition plate can be used as a closet. Also, the space on one side partitioned by the partition plate can be used for other storage.

[0060] When the lower space 210a is used as a workspace, for example, shelf boards are provided on the first leg unit 212 and the second leg unit 213, the first leg unit 212 and the second leg unit 213 are used as storage shelves, and further, a desk Dk is installed between the first leg unit 212 and the second leg unit 213. Thereby, the lower space 210a can be used as a workspace.

[0061] When the upper space 210b is used as a bedroom, for example, the floor unit 211 behind the handrail unit 215 is utilized as a bed. When the upper space 210b is used as a nook room, for example, a desk Dk is installed on the floor unit 211 behind the handrail unit 215. When the upper space 210b is used for loft storage, for example, the floor unit 211 behind the handrail unit 215 is utilized as a storage place for articles. When the upper space 210b is used as a collection room, for example, the floor unit 211 behind the handrail unit 215 is utilized as a place to display collections. Since the handrail unit 215 is a storage furniture type handrail unit, it appropriately stores storage articles and collection articles.

[0062] Also, by changing the width dimension, depth dimension, and height dimension of the floor unit 211, the form of the unit furniture 210 becomes different. That is, FIG. 8(a) is an elevation view (side view and front view) of the unit furniture 210 shown in FIG. 7. For example, when the depth dimension is increased, as shown in FIG. 8(b), the lifting space of the staircase portion 216 can be lengthened. As a result, the number of steps of the staircase portion 216 increases by one, so that the height from the top step board to the upper surface of the floor unit 211 can be lowered, resulting in the advantage that it is easier to lift and lower. In addition, the area of the top step board can be widened and used like a dance floor, improving the ease of lifting and lowering.

[0063] According to this modification, the plurality of leg units 212 and 213 are arranged such that the support plate for the back plate is along the side edge of the floor unit 211 and the support plate for the side plate does not protrude outside the side edge of the floor unit 211. The staircase portion 216 is arranged along the side edge of the floor unit 211 and is attached to the support plate for the back plate in the first leg unit 213 among the plurality of leg units 212 and 213. Therefore, the support plate for the back plate can be used as a part of the staircase portion 216, and the staircase portion 216 can be in a state of being built into the unit furniture 210. As a result, it is not necessary to unitize the staircase portion 216, so that the number of component parts constituting the staircase portion 216 can be reduced as much as possible, and the assembly of the staircase portion 216 can be easily performed.

[0064] 〔Modification 2〕 The unit furniture 310 in FIG. 9 includes a floor unit 311, two first leg units 312, two second leg units 313, a handrail unit 315, and a staircase portion 316. The lower side of the floor unit 311 is a lower space 310a, and the upper side of the floor unit 311 is an upper space 310b. The unit furniture 310 of this modification has a form in which a lifting opening is not formed at the side end of the floor unit 311, and the floor unit 311 is used as a rectangle in plan view. Accordingly, the staircase portion 316 is arranged on one side surface of the unit furniture 310. In addition, the depth dimension of the floor unit 311 is set longer than the depth dimension of the floor unit 211 in the unit furniture 210 shown in FIG. 7.

[0065] The first leg unit 312 is a leg unit without a staircase portion 216, and has at least a back plate and two side plates provided at both ends in the width direction of the back plate, and optionally has a partition plate, a bottom plate, and a shelf plate. And the first leg unit 312 is in a state where the opposite side of the back plate is open, and the open portion is arranged facing the central side of the lower space 310a. Two first leg units 312 are arranged adjacent to each other and support the left end portion of the floor unit 211 from below.

[0066] The second leg unit 313 is a leg unit with a staircase portion 316 attached, and has at least a back plate and two side plates provided at both ends in the width direction of the back plate, and these back plates and side plates are a plurality of support plates. Also, the second leg unit 313 optionally has a partition plate, a bottom plate, and a shelf plate. And the second leg unit 313 is in a state where the opposite side of the back plate is open, and the open portion is arranged facing the central side of the lower space 310a. Two second leg units 313 are arranged adjacent to each other and support the right end portion of the floor unit 311 from below. Also, the two second leg units 313 have their back plates facing right outward, and the staircase portion 316 is attached across these two back plates.

[0067] Since the floor unit 311 is rectangular in plan view, the staircase portion 316 can secure a lifting space having a length equal to the length of the right side edge of the floor unit 311 in plan view. In other words, the lifting direction of the staircase portion 316 is aligned with the length direction of the right side edge of the floor unit 311 in plan view. And this staircase portion 316 is attached to a support plate (back plate) arranged along the lifting direction of the staircase portion 316 in plan view. Also, the top step board of the staircase portion 316 is set to have a large area and is used like a dance floor.

[0068] At the front end of the bed unit 311, a handrail unit 315 is provided along the length direction of the front end. The handrail unit 315 in this modification example is a storage furniture type handrail unit.

[0069] The unit furniture 310 configured as described above can use the lower space 310a and the upper space 310b for various purposes. In the table shown in FIG. 9, it is shown that the lower space 310a can be used as a closet, a workspace, a relaxation space, and a rest space. Also, it is shown that the upper space 310b can be used as a loft storage, a workroom, a collection room, and a bedroom. The usage examples of the lower space 310a and the usage examples of the upper space 310b can be appropriately combined.

[0070] When using the lower space 310a as a closet, for example, a hanger pipe Hp is provided spanning between two side plates in the first leg unit 312 and the second leg unit 313 at the rear side. Also, the inner space in the first leg unit 312 and the second leg unit 313 at the front side can be used for other storage. Thereby, the lower space 310a can be used as a closet.

[0071] When using the lower space 310a as a workspace, for example, a desk Dk is installed in the inner space in the first leg unit 312 or the second leg unit 313 at the rear side. Also, the inner space in the first leg unit 312 and the second leg unit 313 other than where the desk Dk is installed can be used for other storage. Thereby, the lower space 310a can be used as a workspace & closet.

[0072] When using the lower space 310a as a relaxation space, for example, place the sofa Sf in the inner space of the rear first leg unit 312 or the second leg unit 313. Also, the inner spaces of the first leg unit 312 and the second leg unit 313 other than where the sofa Sf is installed can be used as a workspace by installing other storage or a desk Dk. In this way, the lower space 310a can be used as a workspace & relaxation space and a closet. It is preferable to use the space below the seat surface of the sofa Sf as a storage area, as this can improve the storage capacity.

[0073] When using the lower space 310a as a rest space, for example, place the bed Bd in the inner space of the rear first leg unit 312 or the second leg unit 313. Also, the inner spaces of the first leg unit 312 and the second leg unit 313 other than where the bed Bd is installed can be used for other storage. In this way, the lower space 310a can be used as a rest space & closet. Note that instead of the bed Bd, a hammock Hm may be provided by spanning it between the rear first leg unit 312 and the second leg unit 313.

[0074] When using the upper space 310b for loft storage, for example, use the area above the floor unit 311 behind the handrail unit 315 as a storage place for items. When using the upper space 310b as a workroom (enclosed room), for example, install a desk Dk on the floor unit 311 behind the handrail unit 315. When using the upper space 310b as a collection room, for example, use the area above the floor unit 311 behind the handrail unit 315 as a place to display collections. When using the upper space 310b as a bedroom, for example, install a bed Bd on the floor unit 211 behind the handrail unit 315. Since the folding unit 315 is a storage furniture - type folding unit, it appropriately stores storage items and collection items.

[0075] According to this modification example, the plurality of leg units 312 and 313 are arranged such that the support plate for the back plate is along the side edge of the floor unit 311 and the support plate for the side plate does not protrude outside the side edge of the floor unit 311. The staircase portion 316 is arranged along the side edge of the floor unit 311 and is attached to the support plate for the back plate in at least one of the plurality of leg units 313. Therefore, the support plate for the back plate can be used as a part of the staircase portion 316, and the staircase portion 316 can be in a state of being fixedly attached to the unit furniture 310. More specifically, two or more second leg units 313 among the plurality of leg units 312 and 313 are arranged adjacent to each other to support one - side end of the floor unit 311. The support plates for the back plates in the two or more second leg units 313 are arranged adjacent to each other along the right - hand side edge of the floor unit 311. Since the staircase portion 316 is attached to the adjacent support plates for the back plates in the two or more second leg units 313, the adjacent support plates for the back plates can be used as a part of the staircase portion 316, and the staircase portion 316 can be in a state of being fixedly attached to the unit furniture 310. As a result, it is not necessary to unitize the staircase portion 316. Therefore, the number of parts constituting the staircase portion 316 can be reduced as much as possible, and the assembly of the staircase portion 316 can also be easily performed.

[0076] 〔Modification Example 3〕 FIGS. 10 and 11 show an example of a partition body 500 that partitions the upper - side space 410b of the unit furniture 410 placed and provided in the room 1 and the room space RS of the room 1.

[0077] The unit furniture 410 includes a floor unit 411 arranged above the floor 2 and a plurality of leg units (not shown) that support the floor unit 411. A lower - side space (not shown) is formed between the floor unit 411 and the floor 2, and an upper - side space 410b is formed between the floor unit 411 and the ceiling 6.

[0078] The partition body 500 has a single opening panel 510, two partition panels 520 and 530 (the first partition panel 520 on the right side and the second partition panel 530 on the left side), and a movable mechanism for moving each of these panels 510, 520, and 530 against the wall (on the side of wall 4) and storing them. The height dimensions of each of the single opening panel 510 and the two partition panels 520 and 530 are set slightly shorter than the height dimension from the upper surface of the floor unit 411 to the ceiling 6.

[0079] The opening panel 510 has a handle 511. The handle 511 operates a latch (not shown) that protrudes from the left end face of the opening panel 510. When the handle 511 is operated, the latch can be retracted. The latch is inserted into a striker (not shown) formed on the right end face of the first partition panel 520 before the handle 511 is operated, suppressing the rotation of the opening panel 510. When rotating the opening panel 510, the handle 511 is operated to remove the latch from the striker and then rotated.

[0082] The guide rail 540 is formed in a substantially L shape so that each panel 510, 520, 530 can be moved from the front side (the front end side of the unit furniture 410) to the right side (the right end side of the unit furniture 410 and the wall 4 side). At the center and the rear end of the portion of the guide rail 540 located at the wall 4 side on the right, branch portions 540a branching from the main body of the guide rail 540 are integrally formed respectively. Hangers for hanging the first partition panel 520 are accommodated in these branch portions 540a. Further, the guide rail 540 is provided in a state of being embedded in the ceiling 6.

[0083] The rotation shaft 541 of the opening panel 510 is provided at the right end of the front portion of the guide rail 540 and the right end of the front portion of the floor unit 411 of the unit furniture 410, and rotatably supports the right end of the opening panel 510.

[0084] Two hangers are provided on both sides in the width direction at the upper end of the first partition panel 520, and two hangers are provided on both sides in the width direction at the upper end of the second partition panel 530. That is, each partition panel 520, 530 is suspended from the guide rail 540 at two points by these two hangers and can move along the guide rail 540.

[0085] The lock is a French drop lock 543 provided at the lower end of each panel 510, 520, 530 and a receiving plate 544 provided on the upper surface of the floor unit 411 of the unit furniture 410. In the opening panel 510, the French drop lock 543 is provided at the end opposite to the rotation shaft 541, and the receiving plate 544 is provided at the center of the right edge of the floor unit 411 of the unit furniture 410. In the first partition panel 520, the French drop locks 543 are provided at both ends in the width direction, and the receiving plates 544 are provided at one place on the front edge of the floor unit 411 of the unit furniture 410, at the center of the right edge of the floor unit 411 of the unit furniture 410, and at two places on the rear edge of the floor unit 411 of the unit furniture 410. In the second partition panel 530, the French drop lock 543 is provided at the right end in the width direction, and the coin slots 544 are provided at one location on the front edge of the floor unit 411 of the unit furniture 410 and at two locations on the rear edge of the floor unit 411 of the unit furniture 410.

[0086] In a state where the room space RS and the upper space 410b of the unit furniture 410 are partitioned by the panels 510, 520, 530, the panels 510, 520, 530 are arranged in a straight line along the portion located on the front side of the guide rail 540 as shown in FIG. 10(a).

[0087] In a state where the panels 510, 520, 530 are stored close to the wall 4, the opening panel 510 and the first partition panel 520 are arranged in a straight line along the portion located at the right side wall 4 of the guide rail 540, and the first partition panel 520 and the second partition panel 530 are arranged overlapping in the left-right direction.

[0088] When applying the partition body 500 in this modified example to, for example, the examples of the unit furniture 210 and 310 above, the handrail units 215, 315 are removed. Further, the panels 510, 520, 530 are arranged so that they can be stored close to the wall 3 on the side opposite to the staircase portions 216, 316. When applying the partition body 500 in this modified example to, for example, the example of the unit furniture 10 above, the handrail unit 15 is removed. Further, only the first partition panel 520 and the second partition panel 530 are applied, and the opening panel 510 is not applied. Then, the first partition panel 520 and the second partition panel 530 are arranged so that they can be stored close to the wall 3 on the side opposite to the staircase portion 16.

[0089] The lower space 410a and the upper space 410b of the floor unit 411 in the unit furniture 410 are each accessible for people to enter and stay. Therefore, when placed in a room 1 where people are present, such as a living room, it may be difficult to ensure privacy. Therefore, according to the present modification example as described above, the partition body 500 can ensure privacy when the unit furniture 410 is in use.
