Description

Technical Field

[0001] The present invention relates to a space forming device.

Background Art

[0002] In various facilities such as offices and public facilities, a space forming device for working in an internal space isolated from the external space may be installed. The space forming device includes a booth body that forms the internal space, and furniture (for example, chairs, desks, etc.) installed in the booth body. The booth body is configured by combining, for example, a plurality of panels. Users of the space forming device enter the internal space through an entrance formed in the booth body and perform various operations in the internal space.

[0003] For example, Patent Document 1 and Non-Patent Document 1 below disclose a configuration in which a table is fixed to one of a plurality of panels. Further, in the configuration of Patent Document 1 below, a configuration in which a sofa is fixed to a panel arranged at a position facing the table among a plurality of panels is disclosed.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, among the above-described prior arts, in the configuration of Patent Document 1, the entrance and exit of the booth body are formed diagonally forward with respect to the sofa. Therefore, the external space is likely to be reflected in the line of sight of the seated person on the sofa (the user of the space forming device).

[0007] On the other hand, in the configuration of Non-Patent Document 1, since the entrance and exit of the booth body are formed in a range from the rear to the side with respect to the chair, the external space is less likely to be reflected in the line of sight of the seated person on the chair compared to the configuration of Patent Document 1. However, in the configuration of Non-Patent Document 1, due to the relationship of carrying a chair with casters into the booth body, it is necessary to secure a large entrance and exit. Therefore, even in the configuration of Non-Patent Document 1, there is still room for improvement in blocking the external space from the line of sight of the user in the internal space.

[0008] An object of the present invention is to provide a space forming device that makes it difficult for the user in the internal space to be concerned about the external space and can improve the workability in the internal space.

Means for Solving the Problems

[0009] In order to solve the above problems, the present invention adopts the following aspects. A space forming device according to one aspect of the present invention includes a panel unit in which a plurality of panels are combined to form an internal space. The panel unit includes a first side extending in a first direction intersecting in the vertical direction, a second side facing the first side in a second direction intersecting the first direction when viewed from the vertical direction, a third side extending in the second direction and connecting between a first end of the first side and a first end of the second side, and a fourth side extending from a second end of the first side in the second direction and forming an entrance to the internal space between the second end of the second side. The panel unit further includes a first connecting portion connecting the second side and the third side and restricting displacement of the second side and the third side in a direction in which an angle formed by the second side and the third side expands or contracts, and a second connecting portion connecting the first side and the fourth side and restricting displacement of the first side and the fourth side in a direction in which an angle formed by the first side and the fourth side expands or contracts.

[0010] In the space forming device of the above aspect, the first connecting portion may be a table disposed in the internal space.

[0011] In the space forming device of the above aspect, among the table, a surface facing the second side in the second direction may be connected to the second side in a state of being in contact with the second side, and among the table, a surface facing the third side in the first direction may be connected to the third side in a state of being in contact with the third side.

[0012] In the space forming device of the above aspect, among the table, a surface facing the first side in the second direction may be connected to the first side in a state of being in contact with the first side.

[0013] In the space forming device of the above aspect, the second connecting portion may be a seating member disposed in the internal space.

[0014] In the space forming device of the above aspect, the seating member includes a box-shaped support structure and a seat provided on an upper surface of the support structure, and the support structure may be fixed to the first side and the fourth side.

[0015] In the space forming device of the above aspect, the seating member may include a backrest provided at a portion of the upper surface of the support structure that is located on the fourth side of the seat rather than the seat in the first direction.

Effect of the Invention

[0016] According to each of the above aspects, the external space is less likely to be a concern for users of the internal space, and the workability in the internal space can be improved.

Modes for Carrying Out the Invention

[0018] Next, embodiments of the present invention will be described with reference to the drawings. In the embodiments and modifications described below, corresponding components may be denoted by the same reference numerals and description thereof may be omitted. In the following description, expressions indicating relative or absolute arrangements such as "parallel", "orthogonal", "center", "coaxial", etc. not only strictly represent such arrangements, but also represent states in which they are relatively displaced with tolerances or at angles and distances that can obtain the same function. Further, in the present embodiment, "facing each other" includes not only the case where the orthogonal directions (normal directions) of two surfaces coincide with each other, but also the case where the orthogonal directions intersect each other.

[0019] (Space forming device 1) FIG. 1 is a perspective view of the space forming device 1 as viewed from the rear (entrance / exit 26 side). The space forming device 1 shown in FIG. 1 is installed on the floor surface F in various facilities such as offices and public institutions. The space forming device 1 forms an internal space S2 isolated from the external space S1 and is used, for example, when working in the internal space S2. The space forming device 1 includes a panel unit 11, a table 12, and a seating member 13. In the following description, directions such as front, rear, up, down, left, and right indicate the directions as viewed from the user of the seating member 13. Therefore, the front, rear, left, and right directions of the table 12 are based on the direction in which the user of the seating member 13 is facing directly.

[0020] <Panel unit 11> FIG. 2 is a plan view of the space forming device 1. As shown in FIGS. 1 and 2, the panel unit 11 is a so-called self-standing panel (low partition) in which the panels 21 to 24 support each other and stand independently. The panel unit 11 is formed in a square shape in a plan view as viewed from the vertical direction. However, the panel unit 11 may have a shape such as a rectangular shape. Each side of the panel unit 11 is composed of one panel 21 to 24 respectively. The panel unit 11 forms an internal space S2 inside the panel unit 11 by combining a plurality of panels 21 to 24. Specifically, the panels 21 to 24 include a front wall panel (third side) 21, a first side wall panel (first side) 22, a second side wall panel (second side) 23, and a rear wall panel (fourth side) 24.

[0021] Each of the panels 21 to 24 has a configuration in which a plate-shaped base material made of, for example, wood or metal is covered with a decorative material. Note that the panels 21 to 24 may have a configuration formed of non-woven fabric, woven fabric, etc. as long as the outer shape is plate-shaped. Also, a part of the panels 21 to 24 may be composed of glass, mesh, etc.

[0022] The front wall panel 21 forms the front wall of the panel unit 11. The front wall panel 21 stands up from the floor surface F with the front-rear direction (the first direction) as the thickness direction and the left-right direction (the second direction) as the width direction. The first side wall panel 22 forms the left side wall of the panel unit 11. The first side wall panel 22 stands up from the floor surface F with the left-right direction as the thickness direction and the front-rear direction as the width direction. The front end surface (the first end portion) of the first side wall panel 22 is connected to the rear surface at the left end portion of the front wall panel 21 via a connecting tool (not shown). The second side wall panel 23 (the second side) forms the right side wall of the panel unit 11. The second side wall panel 23 faces the first side wall panel 22 in the left-right direction. The second side wall panel 23 stands up from the floor surface F with the left-right direction as the thickness direction and the front-rear direction as the width direction. The front end surface (the first end portion) of the second side wall panel 23 is connected to the rear surface at the right end portion of the front wall panel 21 via a connecting tool (not shown).

[0023] All kinds of dimensions (width, height, thickness) of the front wall panel 21 and the second side wall panel 23 are equal. The height and thickness of the first side wall panel 22 are equal to those of the front wall panel 21 and the second side wall panel 23. The width (the dimension in the front-rear direction) of the first side wall panel 22 is shorter than that of the second side wall panel 23 by the thickness of the rear wall panel 24. However, the dimensions of the front wall panel 21 and the side wall panels 22, 23 may be equal or different respectively.

[0024] Figure 3 is a rear view of the space forming device 1. As shown in FIGS. 1 and 3, the rear wall panel 24 forms the rear wall of the panel unit 11. That is, the rear wall panel 24 faces the front wall panel 21 in the front-rear direction. The rear wall panel 24 stands up from the floor surface F with the front-rear direction as the thickness direction and the left-right direction as the width direction. As shown in FIGS. 2 and 3, the front surface at the left end portion of the rear wall panel 24 is connected to the rear end surface (the second end portion) of the first side wall panel 22 via a connecting tool (not shown). Note that the height and thickness of the rear wall panel 24 are equal to those of the other panels 21 to 23.

[0025] As shown in FIGS. 1 and 3, among the right end portions of the rear wall panel 24, a relief portion 28 that is notched at the upper part relative to the lower part is formed. The relief portion 28 is configured to be inclined toward the left side (the first side wall panel 22 side) as the right end face of the rear wall panel 24 faces upward from below. Therefore, the width (dimension in the left-right direction) of the rear wall panel 24 forms the maximum width portion at the lower part, and gradually decreases upward as it goes from below to above. The width (maximum width) of the lower part of the rear wall panel 24 is shorter than that of the front wall panel 21. In the present embodiment, it is preferable that the width of the lower part of the rear wall panel 24 is set in a range of not less than 1 / 2 times and not more than 3 / 4 times the width of the front wall panel 21. Note that the width of the rear wall panel 24 may be uniform over the entire height in the vertical direction, or may vary in width over the entire height in the vertical direction. Further, the relief portion 28 may be formed by notching the right end portion of the rear wall panel 24 in a stepped shape.

[0026] An entrance / exit 26 that can access the internal space S2 is formed between the right end portion of the rear wall panel 24 and the rear end portion (the second end portion) of the second side wall panel 23. In the present embodiment, the rear end portion of the second side wall panel 23 is located on the extension line of the rear wall panel 24. That is, the right end face of the rear wall panel 24 and the left side face (the face facing the first side wall panel 22) of the second side wall panel 23 face each other in the left-right direction. Therefore, the entrance / exit 26 is open only to the rear and upward. However, the front end portion of the second side wall panel 23 may be located behind or in front of the extension line of the rear wall panel 24.

[0027] FIG. 4 is a side view of the space forming device 1 as viewed from the right side. As shown in FIGS. 1 to 4, the table 12 is at the front part within the internal space S2 and is arranged at an intermediate position in the vertical direction. Specifically, the table 12 is formed in a rectangular plate shape with the left-right direction as the longitudinal direction and the front-rear direction as the short direction. In the illustrated example, the length of the table 12 in the left-right direction is equal to the distance between the side wall panels 22 and 23. The length of the table 12 in the front-rear direction is about half of the width of the side wall panels 22 and 23.

[0028] Table 12 is connected to the panel unit 11 via brackets 31 provided separately on the front wall panel 21 and the side wall panels 22 and 23. In this case, Table 12 is attached to the panel unit 11 in a state where three sides of the outer surface except the rear end face are close to or in contact with the corresponding panels (the front wall panel 21 and the side wall panels 22 and 23). Therefore, Table 12 is connected to the front wall panel 21 via the bracket 31 in a state where the front end face is close to or in contact with the front wall panel 21. Also, Table 12 is connected to the first side wall panel 22 via the bracket 31 in a state where the left end face is close to or in contact with the first side wall panel 22. Table 12 is connected to the second side wall panel 23 via the bracket 31 in a state where the right end face is close to or in contact with the second side wall panel 23.

[0029] In this way, Table 12 is fixed across the intersecting surfaces of adjacent panels (between the front wall panel 21 and the first side wall panel 22, or between the front wall panel 21 and the second side wall panel 23) among the front wall panel 21 and the side wall panels 22 and 23. Therefore, Table 12 functions as a first connecting portion that connects adjacent panels while restricting the displacement of adjacent panels in the direction in which the angle formed by the intersecting surfaces expands or contracts. Note that Table 12 may have a configuration that spans at least between the front wall panel 21 and the second side wall panel 23.

[0030] As shown in FIG. 3, the right end of the table 12 is visible from the rear through the entrance / exit 26. An article storage section 35 is provided at the right end of the table 12. That is, the article storage section 35 is visible from the rear through the entrance / exit 26. The article storage section 35 is formed in a U shape that opens upward. The upper end of the article storage section 35 is attached to the lower surface of the table 12 via a bracket 35a, thereby forming a storage space S3 that opens in the front-rear direction between the lower surface of the table 12. The article storage section 35 supports the articles stored in the storage space S3 from below and from both the left and right sides. Thereby, for example, a third party in the external space can determine the presence or absence of a user of the space forming device 1 based on the presence or absence of articles in the storage space S2. Note that the space forming device 1 may include storage furniture (for example, drawers, shelves, etc.) other than the above-described article storage section 35. Further, the space forming device 1 may be provided with various optional members such as a lighting 38 (see FIG. 1) for illuminating the upper surface of the table 12, a wiring connection section 39 (a power outlet, a LAN port, a USB port, etc.), a wiring duct 40, and a hook as shown in FIGS. 2 and 4.

[0031] <seating member 13> The seating member 13 is a sofa. The seating member 13 is disposed in the internal space S2 at a portion close to the first side wall panel 22 and the rear wall panel 24. Specifically, the seating member 13 includes a support structure 41, a backrest 42, and a seat 43. The support structure 41 is formed in a box shape. The support structure 41 is fixed to both the lower part of the rear wall panel 24 and the lower part of the first side wall panel 22 by screws or the like. That is, the support structure 41 is fixed across the intersecting surfaces of the adjacent panels (the first side wall panel 22 and the rear wall panel 24) that intersect each other. Therefore, the seating member 13 functions as a second connecting portion that connects the adjacent panels 22 and 24 in a state where displacement of the adjacent panels 22 and 24 in a direction in which the angle formed by the intersecting surfaces expands or contracts is restricted.

[0032] The backrest 42 stands upright upward from the rear end portion on the upper surface of the support structure 41. The backrest 42 has a configuration in which, for example, a back plate and a cushion material are covered with an outer skin. The upper end position of the backrest 42 is located below the lower end of the escape portion 28. The backrest 42 is fixed to the rear wall panel 24, for example, by a pin protruding from the back plate being locked in a locking hole provided in the rear wall panel 24. However, the backrest 42 may be fixed to the rear wall panel 24 by screwing or the like. Further, the backrest 42 may be in contact with the upper surface of the support structure 41 or may be spaced upward from the support structure 41. Note that the seating member 13 may be configured not to have the backrest 42. In this case, the rear wall panel 24 may be used as the backrest of the seating member 13. Further, the backrest 42 and the seat 43 may also be fixed to the first side wall panel 22 by engagement between a pin and a locking groove, screwing, or the like. In this case, the backrest 42 and the seat 43 themselves function as the second connecting portion.

[0033] The seat 43 is provided at a portion of the upper surface of the support structure 41 that is located in front of the backrest 42. The seat 43 has a configuration in which, for example, a seat plate and a cushion material are covered with an outer skin. In the example of FIG. 4, the front end of the seat 43 is arranged at the same position in the front-rear direction as the rear end of the table 12. However, the front end of the seat 43 may be arranged in front of or behind the rear end of the table 12.

[0034] As described above, the seating member 13 of the present embodiment is close to or in contact with the first side wall panel 22 and the rear wall panel 24 in a state where at least the support structure 41 is fixed to both the first side wall panel 22 and the rear wall panel 24. In the seating member 13, the widths of the support structure 41, the backrest 42, and the seat 43 are equal to each other. In the present embodiment, the maximum width of the seating member 13 is equal to the width of the lower portion of the rear wall panel 24. Therefore, the right end surface of the seating member 13 is flush with or located to the left of the right end surface in the lower portion of the rear wall panel 24. Therefore, the seating member 13 is arranged at a position where it does not overlap with the entrance / exit 26 when viewed from the rear. That is, the seating member 13 is not visible from the rear through the entrance / exit 26.

[0035] In the above-described space forming device 1, the user can enter and exit between the external space S1 and the internal space S2 through the entrance / exit 26. Further, in the internal space S2, the user can sit on the seating member 13 and work in a state where the surroundings are surrounded by the panel unit 11 and facing the table 12 directly.

[0036] As described above, the space forming device 1 of the present embodiment is configured such that the seating member 13 is fixed in the internal space S1 surrounded by the panel unit 11, adjacent to the rear wall panel 24, and at a position that does not overlap with the entrance / exit 26 when viewed from the rear. According to this configuration, in the internal space S2, since the seating member 13 is arranged adjacent to the rear wall panel 24 and at a position that does not overlap with the entrance / exit 26 when viewed from the rear, it becomes difficult for the external space S1 to be reflected in the line of sight of the user sitting on the seating member 13. As a result, it becomes difficult for the external space S1 to be a concern for the user in the internal space S2, and the workability in the internal space S2 can be improved. Moreover, in the space forming device 1 of the present embodiment, since the seating member 13 is fixed in the internal space S2, it is easier to reduce the opening width of the entrance / exit 26 compared to the case of carrying in and out the seating member through the entrance / exit 26 after the installation of the panel unit 11. Thereby, it becomes more difficult for the external space S1 to be reflected in the line of sight of the user sitting on the seating member 13. Furthermore, the space forming device 1 of the present embodiment forms the entrance / exit 26 between the rear wall panel 24 and the second side wall panel 23, so that the rear wall panel 24 can be continuously extended compared to the case where the entrance / exit is provided in the middle part of the rear wall panel 24, for example. Thereby, it becomes easier to secure the installation space for the seating member 13, and the comfort in the internal space S2 can be improved.

[0037] In the space forming device 1 of the present embodiment, the rear wall panel 24 is configured to face the rear end portion of the second side wall panel 23 in the left-right direction. According to this configuration, the entrance / exit 26 can be opened only to the rear, so that it becomes more difficult for the external space S1 to be reflected in the line of sight of the user sitting on the seating member 13.

[0038] In the space forming device 1 of the present embodiment, the seating member 13 is fixed to the panel unit 11. According to this configuration, the position of the seating member 13 with respect to the panel unit 11 can be stabilized.

[0039] In the space forming device 1 of the present embodiment, the seating member 13 is fixed to the rear wall panel 24. According to this configuration, since the seating member 13 is disposed closer to the rear wall panel 24, the user in the internal space S2 can be disposed closer to the rear wall panel 24. As a result, the external space S1 is less likely to be reflected in the line of sight of the user sitting on the seating member 13.

[0040] In the space forming device 1 of the present embodiment, the seating member 13 is fixed to both of the adjacent panels among the panels 21 to 24. According to this configuration, the connection strength between the adjacent panels can be ensured. Thereby, the displacement of the adjacent panels in the direction in which the angle formed by the intersecting surfaces of the adjacent panels intersecting each other expands or contracts can be restricted. Moreover, by fixing the seating member 13 to the rear wall panel 24 and the first side wall panel 22 adjacent to the seating member 13, it is possible to secure the area of the internal space S2 and simplify the fixing structure of the seating member 13.

[0041] In the space forming device 1 of the present embodiment, the seating member 13 is configured to be forward-facing and seatable, and a table 12 is disposed in front of the seating member 13. According to this configuration, with the user sitting on the seating member 13, the table 12 is disposed in front of the user and the entrance / exit 26 is disposed behind. As a result, the entrance / exit 26 can be opened only at the rear, so that the external space S1 is less likely to be reflected in the line of sight of the user sitting on the seating member 13.

[0042] (Other modifications) The preferred embodiments of the present invention have been described above, but the present invention is not limited to these embodiments. Additions, omissions, substitutions, and other modifications can be made without departing from the spirit of the present invention. The present invention is not limited by the above description, but is limited only by the appended claims. For example, in the above-described embodiment, the configuration in which each side of the panel unit 11 is formed by a single panel 21 to 24 has been described, but the present invention is not limited to this configuration. One side may be composed of a plurality of panels, or a plurality of sides may be composed of a single panel (for example, an L-shaped panel). In the above-described embodiment, the configuration in which both the table 12 and the seating member 13 are disposed in the internal space S2 has been described, but the present invention is not limited to this configuration. The seating member 13 and the table 12 may not be disposed in the internal space S2. However, at least the seating member 13 is preferably disposed in the internal space S2.

[0043] In the above-described embodiment, the configuration in which the seating member 13 is fixed to the first side wall panel 22 and the rear wall panel 24 has been described, but the seating member 13 may be fixed to only one of the panels, or may be fixed to three or more panels. As such a configuration, for example, as shown in FIG. 5, the support structure 41 may be fixed to the front wall panel 21 in addition to the rear wall panel 24 and the first side wall panel 22. In the seating member 13 shown in FIG. 5, a footrest portion 90 may be provided in a portion of the support structure 41 that is located in front of the seat 43 (a portion that is located below the table 12). Further, if the seating member 13 is immovably fixed in the internal space S2, it may be fixed to, for example, the floor surface F or the like. Even in such a case, the seating member 13 is preferably disposed adjacent to the rear wall panel 24. Note that "disposed adjacent" includes that the seating member 13 is disposed along the front surface of the rear wall panel 24, or is disposed rearward (closer to the rear wall panel 24) than the central portion in the front-rear direction within the internal space S2.

[0044] In the above-described embodiment, the seating member 13 has been described by taking a sofa as an example, but the configuration is not limited thereto. The seating member 13 may have a configuration in which the seat is supported by legs, such as a chair, a stool, a bench, etc., in addition to a sofa. In the above-described embodiment, the configuration in which the corner portions of the panel unit 11 are formed at right angles has been described, but the configuration is not limited thereto. The corner portions of the panel unit 11 may be rounded. In the above-described embodiment, among the panels 21 to 24 constituting the panel unit 11, the configuration in which adjacent panels extend in directions perpendicular to each other has been described, but the configuration is not limited thereto. Adjacent panels may extend in directions intersecting each other. Further, the panel unit 11 is not limited to a square shape in plan view, and may be a rectangular shape or the like. Furthermore, in the above-described embodiment, the case where the first direction is the front-rear direction and the second direction is the left-right direction has been described, but the present invention is not limited thereto, and the first direction may be the left-right direction and the second direction may be the front-rear direction.

[0045] Part or all of the space forming device according to the above-described embodiment can be appended as follows. [Appendix 1] Comprising a panel unit in which a plurality of panels are combined to form an internal space, The panel unit is A first side extending in a first direction intersecting in the vertical direction, A second side facing the first side in a second direction intersecting the first direction when viewed from the vertical direction, A third side extending in the second direction and connecting between a first end portion of the first side and a first end portion of the second side, A fourth side extending in the second direction from a second end portion of the first side and forming an entrance to the internal space between the second end portion of the second side, A first connecting portion that connects the second side and the third side and restricts displacement of the second side and the third side in a direction in which an angle formed by the second side and the third side expands or contracts, A space forming device comprising a second connecting portion that connects the first side and the fourth side and restricts displacement of the first side and the fourth side in a direction in which the angle formed by the first side and the fourth side expands or contracts.

[0046] According to the configuration of [Appendix 1], among the second side and the fourth side that form the entrance / exit, the second side is connected to the third side via the first connecting portion, and the fourth side is connected to the first side via the second connecting portion. Thereby, the support strength of the second side and the fourth side can be improved. Therefore, even if it becomes easier for a user to contact the second side and the fourth side when passing through the entrance / exit as the opening width of the entrance / exit is reduced, the robustness against the impact applied to the second side and the fourth side can be improved.

[0047] In the above-described embodiment, the table 12 is adopted as an example of the first connecting portion, and the configuration in which the intersecting surfaces of the front wall panel 21 and the second side wall panel 23 that intersect each other are connected by the table 12 has been described. However, the configuration is not limited to this. For example, as in the space forming device 1 shown in FIG. 6, the first connecting portion 100 may connect the front wall panel 21 and the first side wall panel 22 by being bridged between the upper end surfaces or the lower end surfaces of the front wall panel 21 and the first side wall panel 22. Further, in the above-described embodiment, the seating member 13 is adopted as an example of the second connecting portion, and the configuration in which the intersecting surfaces of the rear wall panel 24 and the first side wall panel 22 that intersect each other are connected by the seating member 13 has been described. However, the configuration is not limited to this. For example, as in the space forming device 1 shown in FIG. 6, the second connecting portion 101 may connect the rear wall panel 24 and the second side wall panel 23 by being bridged between the upper end surfaces or the lower end surfaces of the rear wall panel 24 and the second side wall panel 23. Further, the space forming device 1 may adopt the connecting portions 100 and 101 in addition to the table 12 and the seating member 13.

[0048] Furthermore, as the first connecting portion and the second connecting portion, any configuration may be adopted as long as it restricts the displacement of adjacent panels in a direction in which the angle formed by the intersecting surfaces of adjacent panels that intersect each other expands or contracts. That is, the first connecting portion and the second connecting portion are not limited to configurations such as the table 12 and the seating member 13 (support structure 41) in which the vertical direction is the thickness direction and the outer peripheral surface is arranged along each intersecting surface. The first connecting portion and the second connecting portion may connect the intersecting surfaces by, for example, an angle or the like in which the direction orthogonal to the intersecting surface is the thickness direction. In this case, a configuration without the table 12 and the seating member 13 may be adopted.

[0049] In addition, within the scope not departing from the gist of the present invention, it is possible to appropriately replace the components in the above-described embodiments with well-known components, and the above-described modified examples may be appropriately combined.
