Description

[Technical field]

[0001] The present invention relates to an interior unit that can be used in a room of a building, and more particularly to an interior unit that can be stored when not in use. [Background technology]

[0002] A room in a building is usually surrounded by a ceiling, a floor, and side walls, and can be divided into multiple spaces by placing partition members such as partitions inside the room. Some partition members are movable (see, for example, Patent Document 1). By using a movable partition member as described in Patent Document 1, the placement position of the partition member within the room can be changed as appropriate. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2007-309056 A Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional partition members, including the movable partition member described above, generally stand vertically relative to the floor of a room and divide the indoor space horizontally into a plurality of spaces. On the other hand, if an interior space can be divided vertically (in other words, if a temporary floor can be constructed above the floor of the room), it is expected that each divided space can be used for purposes different from those in the case of a horizontal division.

[0005] Furthermore, conventional partition members are often permanently installed in a predetermined position within a room, and space must be secured within the room for the partition member, but it is desirable for the partition member to be able to be stored when not in use.

[0006] Therefore, the present invention has been made in consideration of the above problems, and its object is to provide an interior unit that vertically divides the interior space of a room in a building and can be stored when not in use. [Means for solving the problem]

[0007] The above problem is solved by an interior unit of the present invention, which is an interior unit used in a room of a building, and is characterized by comprising: a shaft body that is arranged adjacent to a first wall surface of the room and is rotatable while extended horizontally; a strip-shaped body that is wound around the shaft body when the shaft body rotates in a first direction and is unwound along the horizontal direction from the wound state around the shaft when the shaft body rotates in a second direction opposite to the first direction; and a support body that supports the unwound portion of the strip in a state where it is taut along the horizontal direction.

[0008] According to the above configuration, the interior space of the room can be divided vertically by the unwound portion of the band. Also, since the unwound portion of the band can be stored by being wound around the shaft, the interior unit can be stored when not in use.

[0009] In the interior unit of the present invention, the support may be constituted by a first pillar arranged at a position adjacent to a second wall surface that intersects with the first wall surface in the room. According to the above configuration, since the first support pillar forming the support body is disposed near the wall of the room, the first support pillar can be disposed in a location within the room that causes the least possible inconvenience.

[0010] In the interior unit described above, the first support pillar may be movable within the room by means of casters attached to a lower end of the first support pillar. According to the above configuration, it becomes easy to transport the first support to an appropriate placement position within the room.

[0011] The interior unit of the present invention may further include a case that houses the portion of the shaft and the band that is wound around the shaft, a second support that is disposed adjacent to the first wall surface and supports the case, and a connecting member that connects an upper end of the first support to an upper end of the second support. In this case, the end of the unwound portion in the central axis direction of the shaft may be placed on the upper surface of the connecting member. According to the above configuration, the unwound portion of the band can be appropriately supported by the first support and the connecting member.

[0012] Moreover, in the interior unit described above, it is more preferable that at least one of the connecting member and the first support pillar is provided with a joint portion that can be joined to an outer edge portion of the extended portion. According to the above configuration, the outer edge of the unreeled portion of the band-shaped body is joined to at least one of the connecting member and the first support, thereby making it possible to more appropriately support the unreeled portion of the band-shaped body by the first support and the connecting member.

[0013] In the interior unit described above, the connecting member may be detachably attached to the upper end portion of the first support pillar and the upper end portion of the second support pillar. According to the above configuration, when the interior unit is in use, the connecting member can be attached to the upper end of the first support pillar and the upper end of the second support pillar, and when the interior unit is not in use, the connecting member can be removed from the first support pillar and the second support pillar. This allows the interior unit to be freely stored and used (deployed).

[0014] In the interior unit, the first support pillar, the second support pillar, and the connecting member may each be disposed in pairs at different positions in the central axis direction. In this case, the interior unit may further include an installation member that supports the extended portion from below and is installed between the two connecting members in the central axis direction. According to the above configuration, the unwound portion of the strip can be supported by the installation member while the strip is stretched horizontally, thereby making it possible to appropriately support the unwound portion when, for example, an object or a person is placed on the unwound portion of the strip.

[0015] In the interior unit, a guide portion extending horizontally may be formed on a second wall surface intersecting with the first wall surface in the room. In this case, the extended portion may be movable horizontally along the guide portion with an end of the extended portion in the central axial direction of the shaft body engaged with the guide portion. According to the above configuration, the unwound portion of the strip can be stretched horizontally by moving the unwound portion of the strip horizontally along the guide portion formed on the second wall surface, which makes it easier to stretch the unwound portion of the strip horizontally.

[0016] In the interior unit of the present invention, the band may be made of a net or sheet, and the unrolled portion may be stretched horizontally in the room at a position above the floor of the room. According to the above configuration, the unwound portion of the strip is stretched horizontally to form a temporary floor, which can vertically divide the room interior space. Each space in the room interior divided vertically in this way, for example, the space directly below the temporary floor, can be used for various purposes. Effect of the Invention

[0017] According to the present invention, an interior unit is realized which vertically divides the interior space of a room in a building and can be stored away when not in use. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, the interior unit of the present invention will be described in detail with reference to the accompanying drawings. However, the embodiment described below is merely an example for facilitating understanding of the present invention, and does not limit the present invention. In other words, the present invention may be modified or improved without departing from the spirit of the present invention. In addition, the present invention naturally includes its equivalents.

[0020] In the drawings referred to in the following description, each component is illustrated somewhat simplified and schematic to make the description easier to understand. Also, the size (dimension) of each component and the interval between components shown in the drawings are different from the actual ones. In addition, in this specification, "orthogonal," "vertical," "parallel," and "horizontal" include the range of error generally accepted in the technical field of the present invention, and also include states where the directions are shifted within a range of less than a few degrees (e.g., 2 to 3°) from strictly orthogonal, vertical, parallel, and horizontal.

[0021] <Regarding the first embodiment of the present invention> An interior unit according to a first embodiment of the present invention (hereinafter, referred to as an interior unit 10) will be described with reference to FIGS. 1 to 6. FIG. 1, the interior unit 10 is a device that can be used in a room R of a building, and is installed (set up) in the room R. The room R of a building in which the interior unit 10 is used can be, for example, a room in a house (including a detached house and an apartment building). However, the interior unit 10 is not limited thereto, and can also be used in rooms in buildings other than houses, specifically, in factories, buildings, warehouses, stores, facilities, and the like.

[0022] As shown in Figs. 1 to 5, the interior unit 10 includes, as a main component, a continuous belt-like strip 16. The strip 16 is made of, for example, a net or sheet, and as can be seen from Figs. 3 and 5, is wound around the shaft 12 and unwound horizontally before use. The portion of the strip 16 that is unwound horizontally from the wound state around the shaft 12 (hereinafter, horizontal portion 18) is stretched horizontally in room R at a position above the floor F of the room R, as shown in Figs. 1 to 3. As a result, the horizontal portion 18 forms a temporary floor on the floor F, forming a space between the floor F and the horizontal portion 18.

[0023] In other words, by using the interior unit 10, the horizontal portion 18 can vertically divide (partition) the interior space of the room R, and a multi-purpose space can be provided within the room R with a simple configuration. For example, the space between the horizontal portion 18 and the floor F can be used as a temporary storage space for luggage. Alternatively, a person can sit on the horizontal portion 18 and use the space above the horizontal portion 18 as a space for resting or napping. In this case, sofas and cushions are not necessary, and the space required for these can be reduced, thereby increasing the effective floor area within the room R.

[0024] The vertical distance between the horizontal portion 18 and the floor F may be set to a suitable value depending on the purpose of use of the space provided by dividing the interior space of the room R with the horizontal portion 18.

[0025] When the interior unit 10 is not in use, the horizontal portion 18 is wound around the shaft 12 and stored in a case 14, which will be described later, as shown in Figures 4 and 5. In other words, the interior unit 10 can be put away (stored) when not in use. This allows the interior space of the room R to be used more effectively, or more simply, to be used more widely by the amount of the interior unit 10 stored, when the interior unit 10 is not in use.

[0026] Next, a configuration example of the interior unit 10 will be described more specifically. The interior unit 10 is constituted by a shaft body 12, a case 14, a band-shaped body 16, a first support column 20, a second support column 24, a connecting member 26, and a mounting member 30, as shown in FIGS.

[0027] 1 to 5, shaft body 12 is disposed at a position adjacent to first wall surface W1 of room R and extends in the horizontal direction. Shaft body 12 is made of a long rod (e.g., a round bar) with a sufficient length in the extension direction, and is supported in a rotatable state within case 14. Here, the rotation direction of shaft body 12 refers to the rotation direction when shaft body 12 rotates around a central axis along the longitudinal direction of shaft body 12.

[0028] Case 14 is a box-shaped container that extends long along the central axis direction of shaft body 12, and accommodates shaft body 12 and the portion of band-shaped body 16 wound around shaft body 12 therein. Case 14 is disposed at a position where it contacts first wall surface W1, as shown in FIGS. 2 to 5. Also, a shaft support part (not shown) that rotatably supports shaft body 12 is disposed within case 14. Also, of the side walls that constitute case 14, the side wall that is positioned opposite first wall surface W1 is provided with opening 14a that allows the portion of band-shaped body 16 wound around shaft body 12 to be discharged to the outside of case 14 when the portion is unwound from shaft body 12.

[0029] As described above, the strip 16 is a continuous body made of a net or a sheet. The strip 16 may be made of a plurality of rectangular plate pieces connected in the continuous direction of the strip 16, like a known blind curtain. One end of the strip 16 in the continuous direction (hereinafter also referred to as the base) is fixed to the outer circumferential surface of the shaft 12. Therefore, as the shaft 12 rotates in the first direction, the strip 16 is wound around the shaft 12 in a roll (see FIG. 5). Here, the first direction is one direction (direction) in the rotation direction of the shaft 12. The rotation direction (direction) opposite to the first direction is the second direction.

[0030] Furthermore, as the shaft 12 rotates in the second direction, the strip 16 wound around the shaft 12 is unwound from its tip (the end of the strip 16 opposite the base in the continuous direction) and discharged to the outside of the case 14 through the opening 14a of the case 14. The portion of the strip 16 that is unwound and discharged to the outside of the case 14, i.e., the horizontal portion 18, is stretched (pulled out) in the horizontal direction at a position above the floor F of the room R, as shown in Figures 2 and 3. Here, the direction in which horizontal portion 18 is stretched, in other words, the direction in which horizontal portion 18 is unrolled, is a direction perpendicular to the central axis direction of shaft body 12 (the direction penetrating the paper of Figures 2 to 5). Hereinafter, the central axis direction of shaft body 12 will be referred to as the "central axis direction," and the direction in which horizontal portion 18 is unrolled in the horizontal direction will be referred to as the "unrolling direction."

[0031] Moreover, the band-shaped body 16 has a sufficient length in the central axis direction of the shaft body 12, and specifically, has a length that is somewhat shorter than the width (length in the central axis direction) of the first wall surface W1.

[0032] 1 and 3, the first support 20 functions as a support that supports the horizontal portion 18 (the unwound portion) of the strip 16 in a stretched state along the horizontal direction. The first support 20 is a rectangular or cylindrical member, and has an appropriate height to support the horizontal portion 18 in a stretched state along the horizontal direction at a position above the floor F.

[0033] As shown in Figs. 2 and 4, two first supports 20 are arranged at different positions in the central axis direction. As shown in Figs. 2 and 4, each first support 20 is arranged at a position adjacent to a second wall W2 in the room R. The second wall W2 is a wall that intersects with the first wall W1, strictly speaking, is perpendicular to the first wall W1 and continues to the first wall W1, and is arranged on both sides of the first wall W1. In the central axis direction, one of the two first supports 20 is arranged at a position adjacent to one second wall W2, and the other first support 20 is arranged at a position adjacent to the other second wall W2.

[0034] 2 and 4, a pillar connecting body 28 that connects the first pillars 20 to each other is provided between the two first pillars 20 in the central axis direction. The pillar connecting body 28 is made of, for example, a square timber, and one end of the pillar connecting body 28 is connected to the upper end of one of the first pillars 20 and the other end of the pillar connecting body 28 is connected to the upper end of the other first pillar 20, thereby connecting the first pillars 20 to each other. Furthermore, when the first pillars 20 are connected to each other by the pillar connecting body 28, the upper surfaces of the two first pillars 20 and the upper surface of the pillar connecting body 28 are in the same position in the vertical direction, specifically, on the same plane.

[0035] 3 and 5, each of the first supports 20 has casters 22 attached to the lower end of the first support 20, and can be moved in the extension direction within the room R by the casters 22. Here, the two first supports 20 that are separated from each other in the central axis direction are connected by a support connector 28, so that the two first supports 20 move as a unit when moved. The casters 22 may be fixed casters whose moving direction is fixed, or may be swivel casters whose moving direction is variable.

[0036] The second support 24 is located directly below the case 14 to support the case 14, and is disposed in a position adjacent to the first wall surface W1 as shown in Figures 2 to 5. The second support 24 is a rectangular or cylindrical member that is fixed to the floor F and has an appropriate height to support the case 14 at a position above the floor F. In addition, the second support 24 supports the case 14, and thereby supports the shaft body 12 and the portion of the band-shaped body 16 that is wound around the shaft body 12, which are housed in the case 14.

[0037] 2 and 4, two second support columns 24 are disposed at different positions in the central axis direction. Each second support column 24 is disposed at a position adjacent to the first wall surface W1 in the room R, as shown in Figs. 2 and 4. One second support column 24 is disposed at the same position as one of the two first support columns 20, and the other second support column 24 is disposed at the same position as the other of the two first support columns 20, in the central axis direction.

[0038] 2 and 3, the connecting member 26 connects the first support 20 and the second support 24. More specifically, the connecting member 26 is made of, for example, a square timber, and when the first support 20 is a predetermined distance away from the second support 24 in the payout direction, one end of the connecting member 26 is joined to the upper end of the first support 20, and the other end of the connecting member 26 is joined to the upper end of the second support 24. It is also preferable that the connecting member 26 is detachably attached to the upper ends of the first support 20 and the second support 24.

[0039] The joining method between the upper end portions of the first support 20 and the second support 24 and the connecting member 26 is not particularly limited, but for example, the joining structure shown in FIG. 6 may be adopted. In the joining structure of FIG. 6, rectangular groove-shaped fitting recesses 32 are provided on the end faces of the first support 20 and the second support 24 and the end face of the connecting member 26. When the fitting recesses 32 on the support side and the fitting recesses 32 on the connecting member 26 side face each other, the flat fitting member 34 can be inserted into both of the two fitting recesses 32 facing each other. In this way, the fitting member 34 is inserted into the two fitting recesses 32, so that the first support 20 and the second support 24 and the connecting member 26 can be joined via the fitting member 34. In addition, the connecting member 26 can be removed from the upper end portions of the first support 20 and the second support 24 by removing the fitting member 34 from the two fitting recesses 32.

[0040] Similarly to the first support 20 and the second support 24, two connecting members 26 are disposed at different positions in the central axis direction, and each connecting member 26 connects a pair of the first support 20 and the second support 24. A pair of the first support 20 and the second support 24 refers to a first support 20 and a second support 24 disposed at the same position in the central axis direction.

[0041] In a state where the first support 20 and the second support 24 are connected by the connecting member 26, as shown in FIG. 3, the upper surfaces of the first support 20 and the second support 24 and the upper surface of the connecting member 26 are at the same position in the vertical direction, specifically, on the same plane. In this state, the horizontal portion 18 of the band-shaped body 16 is unrolled in the horizontal direction, and finally, the horizontal portion 18 is unrolled to a position where the tip of the band-shaped body 16 is placed on the upper surface of the first support 20. At this time, as shown in FIG. 2, the outer edge portion 18a of the horizontal portion 18, or more precisely, the end portion of the outer edge portion 18a in the central axis direction, is placed on the upper surface of each connecting member 26. In other words, the horizontal portion 18 is unrolled so as to be bridged between the pair of second support 24 and the pair of connecting members 26 in the central axis direction.

[0042] 2, at least one of the connecting member 26 and the first support 20 is provided with a joint that can be joined to the outer edge 18a of the horizontal portion 18. In the configuration shown in FIG. 2, the connecting member 26 and the first support 20 are each provided with a joint (hatched portion in FIG. 2). More specifically, as shown in FIG. 2, a connecting member side joint 26a is provided as a joint on the upper surface of the connecting member 26. Also, a first support side joint 20a is provided as a joint on the upper surface of the first support 20. Furthermore, a column connection body side joint 28a is also provided as a joint on the side end surface of the column connection body 28. The joints may be provided at locations other than those mentioned above, for example, on the front end faces (end faces opposite to the first wall face W1 in the extension direction) of the first support 20 and the support member 28. The joints may also be provided on the side end faces (end faces on the outside in the central axis direction) of the first support 20 and the connecting member 26.

[0043] With the horizontal portion 18 stretched horizontally, the connecting member side joint 26a, the first support column side joint 20a, and the column connecting body side joint 28a are each joined to the outer edge portion 18a of the horizontal portion 18. This allows the outer edge portion 18a of the horizontal portion 18 to be fastened to the connecting member 26, the first support column 20, and the column connecting body 28. As a result, the horizontal portion 18 is supported by the first support column 20, the second support column 24, and the connecting member 26 while being stretched horizontally.

[0044] In addition, the connecting member side joint 26a, the first pillar side joint 20a, and the pillar connecting body side joint 28a can each be detachably joined to the outer edge 18a of the horizontal part 18. That is, when the horizontal part 18 is wound around the shaft body 12 to store the interior unit 10, the outer edge 18a of the horizontal part 18 can be removed from each joint. In addition, each joint is not particularly limited as long as it can be freely attached and detached to the outer edge portion 18a of the horizontal portion 18. For example, hook-and-loop fasteners, zipper-type fasteners, pressure-sensitive tape, a button fastening structure, and a hook-and-loop fastening structure can be used.

[0045] As described above, the horizontal portion 18 of the band 16, stretched horizontally, is supported by the two first supports 20, the two second supports 24, and the two connecting members 26 to construct a roughly table-shaped interior unit 10. In this state, the interior unit 10 becomes usable, and more specifically, the horizontal portion 18 functions as a temporary floor, dividing (separating) the interior space of the room R in the vertical direction.

[0046] Furthermore, when the two sets of first support columns 20 and second support columns 24 are connected by the connecting members 26, a mounting member 30 is mounted between the two connecting members 26 in the intermediate axis direction as shown in Figures 2 and 3. The mounting member 30 supports the horizontal portion 18 from below, and a plurality of mounting members 30 may be disposed as shown in Figure 3. For example, two mounting members 30 may be disposed in an X-shaped crossing state as shown in the same figure.

[0047] Each of the installation members 30 is, for example, an expandable rod (expandable rod) and is disposed obliquely with respect to the two connecting members 26. Specifically, a hole (not shown) is formed in each of the end of one connecting member 26 on the first support 20 side and the end of the other connecting member 26 on the second support 24 side, and the end of the rod constituting the installation member 30 can be inserted into the hole. As a result, as shown in FIG. 3, the two installation members 30 are disposed between the two connecting members 26 in an X-shaped cross state, and each installation member 30 is connected to both of the two connecting members 26. At this time, the rod constituting the installation member 30 is expandable as described above, and when it is connected to the two connecting members 26, it is connected to each connecting member 26 in a slightly compressed state, that is, in a stretched state.

[0048] As described above, by disposing the installation member 30 below the horizontal portion 18 stretched along the horizontal direction, even if an object or person is placed on the horizontal portion 18, the load can be received by the installation member 30. This allows the horizontal portion 18 on which an object or person is placed to be appropriately supported by the installation member 30.

[0049] Moreover, the installation members 30 are detachably attached to the connecting members 26, and can be removed from the respective connecting members 26 when the interior unit 10 is not in use. Moreover, as described above, the connecting members 26 can be detachably joined to the first support column 20 and the second support column 24, and can be removed from the respective upper ends of the first support column 20 and the second support column 24 when the interior unit 10 is stored.

[0050] With the above configuration, when the interior unit 10 is not in use, the installation member 30 and the connecting member 26 can be removed, the first support 20 can be moved to a predetermined location (storage location), and the extended horizontal portion 18 can be wound around the shaft body 12, thereby storing (putting away) the interior unit 10.

[0051] <Second embodiment of the present invention> Next, as another example of the interior unit of the present invention, a second embodiment different from the above-mentioned first embodiment will be described with reference to Figures 7 to 11. In Figures 7 to 11, the same reference numerals as in the first embodiment are used for parts and devices common to the first embodiment.

[0052] The interior unit according to the second embodiment (hereinafter, interior unit 10X) has a configuration generally common to the interior unit 10 according to the first embodiment, as shown in Figs. 7 to 11. On the other hand, in the interior unit 10X, the second support pillar 24 is not provided, and the case 14 is fixed by the first wall surface W1 and the second wall surface W2, as shown in Figs. 8 and 10. That is, in the second embodiment, the case 14 is disposed in a state where it is sandwiched between the two second wall surfaces W2 in the central axial direction.

[0053] In addition, in the second embodiment, each of the two first supports 20 does not move and is fixed to the floor F, specifically, it is located a predetermined distance away from the first wall surface W1 in the extension direction and adjacent to the second wall surface W2 in the central axis direction.

[0054] 7, 9, and 11, in the second embodiment, a slit-groove-like guide portion 36 extending linearly along the horizontal direction (specifically, the extension direction) is formed on each of the two second wall surfaces W2. The guide portion 36 extends in the extension direction from the end of the second wall surface W2 adjacent to the first wall surface W1 to the position where the first support column 20 is fixed.

[0055] An end portion in the central axis direction of the outer edge 18a of the horizontal portion 18 of the band-shaped body 16 is inserted into the guide portion 36. Strictly speaking, the tip of the horizontal portion 18 is wider than the other portions, and an end portion in the central axis direction of the outer edge 18a at the tip of the horizontal portion 18 is inserted into and engaged with the guide portion 36. That is, in the second embodiment, as shown in Figs. 8 to 11, the horizontal portion 18 is movable in the horizontal direction (more specifically, the payout direction) along the guide portion 36 with an end portion in the central axis direction of the outer edge 18a engaged with the guide portion 36.

[0056] When using the interior unit 10X configured as described above, the horizontal portion 18 of the band 16 is unrolled (pulled out) horizontally along the guide portion 36. Then, when the tip of the band 16 reaches a position directly above the upper surface of the first support 20 in the unrolling direction, the portion of the outer edge 18a of the horizontal portion 18 that corresponds to the tip is joined to the first support-side joint 20a and the support-side joint 28a. Through this procedure, the interior unit 10X is ready for use. When the internal unit 10X is not in use, the horizontal portion 18 can be wound around the shaft body 12 by following the steps described above in reverse order to store (put away) the internal unit 10X.

[0057] As described above, in the second embodiment, similarly to the first embodiment, the horizontal portion 18 of the strip 16 is stretched horizontally to form a temporary floor, and the interior space of the room R of the building can be divided vertically. Moreover, as described above, the interior unit 10X can be stored when not in use. Furthermore, in the second embodiment, the horizontal portion 18 can be moved horizontally along the guide portion 36 formed on the second wall surface W2, making it easier to stretch the horizontal portion 18 horizontally. From this viewpoint, the second embodiment is more preferable. On the other hand, in the second embodiment, it is necessary to form the guide portion 36 on the second wall surface W2, and if the guide portion 36 is not formed on the second wall surface W2 in an existing building, work is required to newly form the guide portion 36 on the second wall surface W2. In contrast, in the first embodiment, such work is not necessary, and from this viewpoint, the first embodiment is more preferable. [Explanation of symbols]
