Description

The present invention relates to a space forming device.

In various facilities such as offices and public facilities, a space forming device may be installed to perform work in an internal space isolated from the external space. The space forming device comprises a booth body that forms the internal space, and fixtures (e.g., chairs, desks, etc.) installed within the booth body. The booth body is composed, for example, of a combination of multiple panels. Users of the space forming device enter the internal space through an entrance formed within the booth body, and perform various tasks within the internal space.

For example, Patent Document 1 and Non-Patent Document 1 listed below disclose a configuration in which a table is fixed to one of a plurality of panels.
In addition, the configuration of Patent Document 1 below discloses a configuration in which a sofa is fixed to a panel that is positioned opposite a table among multiple panels, while the configuration of Non-Patent Document 1 below allows a chair with casters to be brought in through the entrance of the booth body.

Okamura Corporation, "Office Furniture General Catalog 2019", December 2018, P. 567-P. 568

However, in the configuration of Patent Document 1, among the above-mentioned conventional technologies, the entrance to the booth body is formed diagonally forward from the sofa. Therefore, the outside space is easily reflected in the line of sight of the person sitting on the sofa (the user of the space forming device).

On the other hand, in the configuration of Non-Patent Document 1, the entrance and exit of the booth body is formed in a range extending from the rear to the side of the chair, so that the external space is less likely to be visible to the seated person in the chair than in the configuration of Patent Document 1.
However, in the configuration of Non-Patent Document 1, a large entrance and exit must be secured in order to carry chairs with casters into the booth body. Therefore, even with the configuration of Non-Patent Document 1, there is still room for improvement in terms of blocking the external space from the line of sight of users in the internal space.

The present invention aims to provide a space-forming device that makes it less distracting for users of the interior space from the exterior space and improves workability in the interior space.

In order to solve the above problems, the present invention employs the following aspects.
A space forming device according to one aspect of the present invention comprises a panel unit formed by combining a plurality of panels to form an internal space, and a seating member arranged in the internal space, the panel unit comprising a first side extending in a first direction intersecting the vertical direction, a second side opposite 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 a first end of the first side and a first end of the second side, and a fourth side extending in the second direction from the second end of the first side and forming an entrance/exit to the internal space between the second end of the second side and the fourth side, the seating member being fixed in the internal space at a position adjacent to the fourth side and not overlapping with the entrance/exit when viewed from the first direction.

According to this aspect, the seating member is disposed in the interior space adjacent to the fourth side and at a position not overlapping with the entrance when viewed from the first direction, so that the external space is less likely to be seen by a user seated on the seating member. This makes it less likely for a user in the interior space to be distracted by the external space, and improves workability in the interior space.
Moreover, in the space forming device of this embodiment, since the seating member is fixed in the internal space, it is easier to reduce the opening width of the doorway compared to when the seating member is brought in and out through the doorway after the panel unit is installed. This makes it less likely that the external space will be visible to the user sitting on the seating member.
Furthermore, by forming an entrance between the fourth side and the second side, the space forming device of this aspect can make the fourth side extend continuously, compared to a case where an entrance is provided in the middle of the fourth side, for example. This makes it easier to secure an installation space for the seating member, and can improve the comfort of the interior space.

In the space forming device of the above aspect, it is preferable that the fourth side faces a second end of the second side in the second direction.
According to this aspect, the entrance can be opened only in the first direction, so that the external space is less likely to be seen by a user seated on the seating member.

In the space forming device of the above aspect, it is preferable that the seating member is fixed to the panel unit.
According to this aspect, the position of the seating member relative to the panel unit can be stabilized.

In the space forming device of the above aspect, it is preferable that the seating member is fixed to the fourth side.
According to this aspect, since the seating member is disposed closer to the fourth side, the user in the internal space can be disposed closer to the fourth side. This makes it more difficult for the external space to be seen by the user seated on the seating member.

In the space forming device of the above aspect, it is preferable that the seating member is fixed to two intersecting sides of the panel unit.
According to this aspect, the connection strength between the adjacent panels can be ensured, and thus it is possible to restrict the displacement of the adjacent panels in a direction that increases or decreases the angle between the intersecting surfaces of the adjacent panels.

In the space forming device of the above aspect, it is preferable that the seating member is fixed to the first side and the fourth side.
According to this aspect, by fixing the seating member to the fourth side and the first side adjacent to the seating member, it is possible to ensure the area of the internal space and simplify the fixing structure of the seating member.

In the space forming device of the above aspect, it is preferable that the seating member allows a user to sit facing the third side, and that a table is arranged in the internal space at a position adjacent to the third side.
According to this aspect, when a user is seated on the seating member, the table is disposed in front of the user and the entrance is disposed behind the user. This allows the entrance to be opened only to the rear, making it more difficult for the user seated on the seating member to see the outside space.

According to each of the above aspects, users of the interior space are less likely to be bothered by the exterior space, and workability in the interior space can be improved.

Next, an embodiment of the present invention will be described with reference to the drawings. In the embodiments and modifications described below, the same reference numerals may be used to designate corresponding configurations, and the description may be omitted. In the following description, expressions indicating relative or absolute arrangements, such as "parallel," "orthogonal," "center," and "coaxial," do not only strictly indicate such arrangements, but also indicate a state in which there is a relative displacement with an angle or distance to the extent that a tolerance or the same function is obtained. In this embodiment, "facing" does not only mean that the orthogonal directions (normal directions) of the two surfaces are aligned with each other, but also includes cases in which the orthogonal directions intersect with each other.

(Space forming device 1)
FIG. 1 is a perspective view of the space forming device 1 as seen from the rear (the entrance/exit 26 side).
The space forming device 1 shown in Fig. 1 is installed on a floor surface F in various facilities such as offices and public institutions. The space forming device 1 forms an internal space S2 isolated from an external space S1, and is used, for example, when performing work 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/back, up/down, left/right, etc. refer to directions as seen by a user of the seating member 13. Therefore, the front/back/left/right directions of the table 12 are based on the direction in which a user of the seating member 13 faces.

<Panel unit 11>
FIG. 2 is a plan view of the space forming device 1. As shown in FIG.
As shown in FIG. 1 and FIG. 2, the panel unit 11 is a so-called freestanding panel (low partition) in which the panels 21 to 24 support each other and stand on their own. The panel unit 11 is formed in a square shape in a plan view seen from the top and bottom direction. However, the panel unit 11 may have a rectangular shape or other shape. Each side of the panel unit 11 is composed of one panel 21 to 24. The panel unit 11 forms an internal space S2 inside the panel unit 11 by combining the multiple panels 21 to 24 together. 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.

Each of the panels 21-24 is constructed with a plate-shaped base material made of, for example, wood or metal, covered with a decorative material. Note that the panels 21-24 may be made of nonwoven fabric, woven fabric, or the like, so long as they have a plate-shaped exterior. Also, a portion of the panels 21-24 may be made of glass, mesh, or the like.

The front wall panel 21 constitutes a front wall of the panel unit 11. The front wall panel 21 stands upright from the floor surface F with the front-rear direction (first direction) as its thickness direction and the left-right direction (second direction) as its width direction.
The first side wall panel 22 constitutes the left wall of the panel unit 11. The first side wall panel 22 stands upright from the floor surface F with the left-right direction being the thickness direction and the front-rear direction being the width direction. The front end surface (first end) of the first side wall panel 22 is connected to the rear surface of the left end portion of the front wall panel 21 via a connector (not shown).
The second sidewall panel 23 (second side) constitutes the right side wall of the panel unit 11. The second sidewall panel 23 faces the first sidewall panel 22 in the left-right direction. The second sidewall panel 23 stands upright from the floor surface F with the left-right direction being the thickness direction and the front-rear direction being the width direction. The front end surface (first end) of the second sidewall panel 23 is connected to the rear surface of the right end portion of the front wall panel 21 via a connector (not shown).

The various dimensions (width, height, thickness) of the front wall panel 21 and the second side wall panel 23 are all 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 (front-to-rear dimension) 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.

FIG. 3 is a rear view of the space forming device 1. FIG.
As shown in Figures 1 and 3, the rear wall panel 24 constitutes 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 upright from the floor surface F with the front-rear direction as its thickness direction and the left-right direction as its width direction. As shown in Figures 2 and 3, the front surface at the left end portion of the rear wall panel 24 is connected to the rear end surface (second end portion) of the first side wall panel 22 via a connector (not shown). The height and thickness of the rear wall panel 24 are equal to those of the other panels 21 to 23.

1 and 3, the upper part of the right end of the rear wall panel 24 is cut out from the lower part to form a relief portion 28. The relief portion 28 is configured such that the right end surface of the rear wall panel 24 is inclined toward the left side (the first side wall panel 22 side) as it moves from the bottom to the top. Therefore, the width (dimension in the left-right direction) of the rear wall panel 24 is maximum at the bottom, and gradually decreases from the bottom to the top at the top. 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 this embodiment, the width of the lower part of the rear wall panel 24 is preferably set in a range of about 1/2 to 3/4 of the width of the front wall panel 21. The width of the rear wall panel 24 may be uniform throughout the entire height in the vertical direction, or may vary throughout the entire height in the vertical direction. The relief portion 28 may be cut out in a stepped shape at the right end of the rear wall panel 24.

Between the right end of the rear wall panel 24 and the rear end (second end) of the second side wall panel 23, an entrance 26 is formed for accessing the internal space S2. In this embodiment, the rear end 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 of the second side wall panel 23 (the face facing the first side wall panel 22) face each other in the left-right direction. Therefore, the entrance 26 is only open to the rear and upward. However, the front end of the second side wall panel 23 may be located rearward or forward of the extension line of the rear wall panel 24.

<Table 12>
FIG. 4 is a side view of the space forming device 1 as seen from the right side.
1 to 4, the table 12 is disposed at the front of the internal space S2, at a vertically central position. Specifically, the table 12 is formed in a rectangular plate shape with the left-right direction as the long side and the front-rear direction as the short side. In the illustrated example, the left-right length of the table 12 is equal to the distance between the side wall panels 22, 23. The front-rear length of the table 12 is approximately half the width of the side wall panels 22, 23.

The table 12 is connected to the panel unit 11 via brackets 31 provided on the front wall panel 21 and the side wall panels 22, 23. In this case, the table 12 is attached to the panel unit 11 with three of its outer surfaces, excluding the rear end surface, in close proximity to or in contact with the corresponding panels (the front wall panel 21 and the side wall panels 22, 23). Therefore, the table 12 is connected to the front wall panel 21 via the brackets 31 with its front end surface in close proximity to or in contact with the front wall panel 21. The table 12 is also connected to the first side wall panel 22 via the brackets 31 with its left end surface in close proximity to or in contact with the first side wall panel 22. The table 12 is connected to the second side wall panel 23 via the brackets 31 with its right end surface in close proximity to or in contact with the second side wall panel 23.

In this way, the table 12 is fixed across the intersecting planes of adjacent panels (the front wall panel 21 and the first side wall panel 22, or the front wall panel 21 and the second side wall panel 23) between the front wall panel 21 and the side wall panels 22, 23. Therefore, the table 12 functions as a first connecting part that connects adjacent panels while restricting the displacement of the adjacent panels in the direction that increases or decreases the angle between the intersecting planes. Note that the table 12 may be configured to span at least the front wall panel 21 and the second side wall panel 23.

As shown in FIG. 3, the right end of the table 12 is visible from the rear through the entrance 26. An item storage section 35 is provided at the right end of the table 12. That is, the item storage section 35 is visible from the rear through the entrance 26. The item storage section 35 is formed in a U-shape that opens upward. The upper end of the item storage section 35 is attached to the underside of the table 12 via a bracket 35a, thereby forming a storage space S3 that opens in the front-rear direction between the item storage section 35 and the underside of the table 12. The item storage section 35 supports items stored in the storage space S3 from below and both the left and right sides. This allows, for example, a third party in the external space to determine the presence or absence of a user of the space forming device 1 based on the presence or absence of items in the storage space S2. The space forming device 1 may be provided with storage fixtures (e.g., drawers, shelves, etc.) other than the above-mentioned item storage section 35. The space forming device 1 may also be provided with various optional components such as lighting 38 (see FIG. 1) that illuminates the top surface of the table 12, wiring connection parts 39 (such as electrical outlets, LAN ports, and USB ports) as shown in FIGS. 2 and 4, wiring ducts 40, and hooks.

<Seating member 13>
The seating member 13 is a sofa. The seating member 13 is disposed in a portion of the internal space S2 that is located closer 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 with 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). Therefore, the seating member 13 functions as a second connecting portion that connects the adjacent panels 22, 24 to each other in a state in which the displacement of the adjacent panels 22, 24 in a direction in which the angle between the intersecting surfaces increases or decreases.

The backrest 42 stands upward from the rear end of the upper surface of the support structure 41. The backrest 42 is, for example, a structure in which the back plate and the cushioning material are covered with an outer skin. The upper end position of the backrest 42 is located below the lower end of the relief portion 28. The backrest 42 is fixed to the rear wall panel 24, for example, by a pin protruding from the back plate being engaged in an engagement 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. 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. 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. The backrest 42 and the seat 43 may also be fixed to the first side wall panel 22 by engaging a pin with a locking groove, or by screwing. In this case, the backrest 42 and the seat 43 themselves function as the second connecting part.

The seat 43 is provided on a portion of the upper surface of the support structure 41 that is located in front of the backrest 42. The seat 43 is configured, for example, with a seat plate and cushioning material covered with an outer skin. In the example of FIG. 4, the front end of the seat 43 is located at a position equivalent in the front-to-rear direction to the rear end of the table 12. However, the front end of the seat 43 may be located forward or rearward of the rear end of the table 12.

In this manner, the seating member 13 of this embodiment is in close proximity to or in contact with the first side wall panel 22 and the rear wall panel 24 with at least the support structure 41 fixed to both the first side wall panel 22 and the rear wall panel 24. In the seating member 13, the support structure 41, the backrest 42, and the seat 43 have the same width. In this embodiment, the maximum width of the seating member 13 is the same as the width of the lower part of the rear wall panel 24. Therefore, the right end face of the seating member 13 is located flush with or to the left of the right end face of the lower part of the rear wall panel 24. Therefore, the seating member 13 is located in a position that does not overlap with the entrance 26 when viewed from the rear. In other words, the seating member 13 is not visible from the rear through the entrance 26.

In the space forming device 1 described above, a user can enter and exit the external space S1 and the internal space S2 through the entrance 26. In addition, by sitting on the seating member 13 in the internal space S2, the user can work while being surrounded by the panel units 11 and facing the table 12.

In this way, the space forming device 1 of this embodiment is configured so that the seating member 13 is fixed within 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 behind.
According to this configuration, in the internal space S2, the seating member 13 is disposed adjacent to the rear wall panel 24 and at a position not overlapping with the entrance/exit 26 when viewed from behind, so that the external space S1 is less likely to be seen by a user sitting on the seating member 13. This makes it less likely that a user of the internal space S2 will be bothered by the external space S1, and improves workability in the internal space S2.
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 where the seating member is carried in and out through the entrance/exit 26 after the installation of the panel unit 11. This makes it more difficult for the external space S1 to be seen by the user seated on the seating member 13.
Furthermore, in the space forming device 1 of the present embodiment, by forming the entrance 26 between the rear wall panel 24 and the second side wall panel 23, the rear wall panel 24 can be extended continuously, as compared to a case where the entrance is provided in the middle of the rear wall panel 24. This makes it easier to ensure the installation space for the seating member 13, and improves the comfort of the interior space S2.

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 26 can be opened only to the rear, so that the external space S1 is less likely to be seen by a user seated on the seating member 13.

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 relative to the panel unit 11 can be stabilized.

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 seen by the user seated on the seating member 13.

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 .
This configuration ensures the connection strength between the adjacent panels, thereby restricting the displacement of the adjacent panels in a direction that increases or decreases the angle between the intersecting surfaces of the adjacent panels.
Furthermore, 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 ensure the area of the internal space S2 and simplify the fixing structure of the seating member 13, etc.

In the space forming device 1 of the present embodiment, the seating member 13 is configured to allow a person to sit facing forward, and the table 12 is disposed in front of the seating member 13 .
According to this configuration, when a user is seated on the seating member 13, the table 12 is disposed in front of the user and the entrance/exit 26 is disposed behind the user. This allows the entrance/exit 26 to be opened only to the rear, so that the external space S1 is less likely to be seen by the user seated on the seating member 13.

(Other Modifications)
Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Addition, omission, substitution, and other modifications of the configuration are possible 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 scope of the attached claims.
For example, in the above embodiment, a configuration has been described in which each side of the panel unit 11 is formed by one panel each of the panels 21 to 24, but this is not limited to the configuration. One side may be formed by multiple panels, or multiple sides may be formed by a single panel (for example, an L-shaped panel).
In the above 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 do not have to be disposed in the internal space S2. However, it is preferable that at least the seating member 13 is disposed in the internal space S2.

In the above embodiment, the seating member 13 is fixed to the first side wall panel 22 and the rear wall panel 24. However, 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 leg rest 90 may be provided on a portion of the support structure 41 located in front of the seat 43 (a portion located below the table 12).
As long as the seating member 13 is fixed in the internal space S2 so as not to move, it may be fixed to, for example, the floor surface F. Even in such a case, the seating member 13 is preferably disposed adjacent to the rear wall panel 24. Note that "disposed adjacent to" includes the seating member 13 being disposed along the front surface of the rear wall panel 24 and being disposed rearward of the center in the front-rear direction within the internal space S2 (closer to the rear wall panel 24).

In the above embodiment, the seating member 13 is described as a sofa, but is not limited to this configuration. The seating member 13 may be a chair, a stool, a bench, or the like, other than a sofa, with a seat supported by legs.
In the above embodiment, the corners of the panel unit 11 are formed at right angles, but the present invention is not limited to this configuration. The corners of the panel unit 11 may be rounded.
In the above embodiment, a configuration has been described in which adjacent panels of the panels 21 to 24 constituting the panel unit 11 extend in directions perpendicular to each other, but this is not limited to this configuration. Adjacent panels only need to extend in directions that intersect with each other. In addition, the panel unit 11 is not limited to a square shape in a plan view, and may be rectangular or the like. Furthermore, in the above embodiment, a case has been described in which the first direction is the front-rear direction and the second direction is the left-right direction, but this is not limited to this, and the first direction may be the left-right direction and the second direction may be the front-rear direction.

A part or all of the space forming device according to the above-described embodiment can be additionally described as follows.
[Appendix 1]
A panel unit is comprised of multiple panels that are combined together to form an internal space,
The panel unit includes:
a first side extending in a first direction intersecting the up-down direction;
a second side facing the first side in a second direction intersecting the first direction when viewed from the top-bottom direction;
a third side extending in the second direction and connecting a first end of the first side and a first end of the second side;
a fourth side extending in the second direction from the second end of the first side and forming an entrance to the internal space between the fourth side and the second end 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 between the second side and the third side increases or decreases;
A space forming device comprising: a second connecting portion that connects the first side and the fourth side and regulates displacement of the first side and the fourth side in a direction in which the angle between the first side and the fourth side is enlarged or reduced.

According to the configuration of [Appendix 1], of the second and fourth sides that form the entrance, the second side is connected to the third side via the first connecting part, and the fourth side is connected to the first side via the second connecting part. This improves the support strength of the second and fourth sides. Therefore, even if users are more likely to come into contact with the second and fourth sides when passing through the entrance as the opening width of the entrance is reduced, the robustness of the second and fourth sides against impacts applied thereto can be improved.

In the above-described embodiment, the table 12 is used 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 are connected to each other by the table 12 has been described, but the present invention is not limited to this configuration. For example, as in the space forming device 1 shown in Fig. 6, the first connecting portion 100 may be bridged between the upper end surfaces or the lower end surfaces of the front wall panel 21 and the first side wall panel 22 to connect the front wall panel 21 and the first side wall panel 22.
In the above embodiment, the seating member 13 is used as an example of the second connecting portion, and the configuration in which the mutually intersecting surfaces of the rear wall panel 24 and the first side wall panel 22 are connected by the seating member 13 has been described, but the present invention is not limited to this configuration. For example, as in the space forming device 1 shown in Fig. 6, the second connecting portion 101 may be bridged between the upper end surfaces or the lower end surfaces of the rear wall panel 24 and the second side wall panel 23 to connect the rear wall panel 24 and the second side wall panel 23. Furthermore, the space forming device 1 may employ each connecting portion 100, 101 in addition to the table 12 and the seating member 13.

Furthermore, the first connecting portion and the second connecting portion may be configured to restrict the displacement of adjacent panels in a direction in which the angle between the intersecting surfaces of adjacent panels increases or decreases. In other words, the first connecting portion and the second connecting portion are not limited to a configuration in which the thickness direction is the up-down direction, such as the table 12 and the seating member 13 (support structure 41), and the outer circumferential surface is disposed along each intersecting surface. The first connecting portion and the second connecting portion may connect the intersecting surfaces, for example, by an angle whose thickness direction is perpendicular to the intersecting surfaces. In this case, the configuration may not have the table 12 or the seating member 13.

In addition, the components in the above-described embodiment may be replaced with well-known components as appropriate without departing from the spirit of the present invention, and the above-described modified examples may be combined as appropriate.
