Description

[Technical field]

[0001] The present invention relates to a chair device. [Background technology]

[0002] It is already known that chair devices with various designs can be constructed by removably attaching multiple seats and tabletops to a base structure. This type of chair device is configured so that the design can be easily changed by combining the seats, tabletops, and base structures (see, for example, Patent Document 1, etc.). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-54835 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional chair device, when changing the design to, for example, an I-shape or L-shape, it is necessary to use a dedicated base structure and seat corresponding to the desired layout. Therefore, it is necessary to diversify (multiply) the types of base structure and seat for each layout, which leads to high costs and makes it difficult to flexibly respond to various user needs.

[0005] Furthermore, for example, chair devices installed in lobbies, waiting rooms, etc., are configured to accommodate multiple users, and recently, even for this type of chair device, there is a demand for it to have a moderate degree of closedness so that it is less susceptible to interference from others.

[0006] However, the conventional chair device does not have a partition-like component to separate users seated next to each other, and so in this respect too, there is a problem in that it is not possible to flexibly respond to user needs. [Means for solving the problem]

[0007] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a chair apparatus which has been improved by examining the current situation as described above.

[0008] The chair device according to the present invention includes a base structure having legs that contact a floor, and a plurality of components attached to the base structure, the components including a plurality of chairs each having a seat, and one or a plurality of plate-like panel bodies positioned on the sides of the chairs and extending in the front-rear direction, the panel body including an extension that protrudes forward beyond the front end of the seat. The panel body is fixed to at least one of the plurality of chairs, and is attached to the base structure as a chair unit including the panel body. This is what it is.

[0009] In the chair device of the present invention, when the panel body is placed on one side of at least one of the multiple chairs, the width in the front-to-back and left-to-right directions in a planar view, excluding the extension portion, may be standardized to predetermined dimensions.

[0010] In the chair device of the present invention, when the panel body is placed on one side of at least one of the multiple chairs, excluding the extension portion, it may be configured in a square shape with equal widths in the front-to-back and left-to-right directions when viewed in a plane.

[0011] In the chair device of the present invention, an end panel having the same shape as the panel body may be disposed on the other side of at least one of the plurality of chairs.

[0012] In the chair device of the present invention, the parts include a top plate disposed on the other side of the chair, An end panel having the same shape as the panel body is disposed on the other side of at least one of the plurality of chairs, The end panel is disposed on the other side of the chair across the top plate. Location It may be arranged so that

[0014] In the chair device of the present invention, at least one of the multiple chairs has a backrest, the backrest comprising a plate-shaped body and a cushion body protruding forward from the plate-shaped body, the height of the plate-shaped body being set higher than the cushion body, and the plate-shaped body and the panel body being set to the same height. Effect of the Invention

[0015] According to the chair device of the present invention, it is not necessary to diversify the types of seats for each desired layout, and various user needs can be flexibly met while keeping costs down. By using the chair device of the present invention, when separating users seated next to each other, it is only necessary to select a panel body, and it is easy to set it to have a moderate degree of closure (closeness) so that it is difficult for others to interfere, and it is possible to flexibly meet user needs. It blocks the line of sight of the person next to you and improves the feeling of being enclosed, making it easier to relax and concentrate. Since it can block the flying of droplets of the seated person between the adjacent plate-shaped panel bodies, it is effective in preventing droplet infection of various viruses such as the new coronavirus and influenza.

[0017] Next, an embodiment of the present invention will be described with reference to the drawings. In the following description, the terms "front-rear" and "left-right" are used to specify directions, but these are based on the orientation of the user of a chair device as a piece of furniture using the component unit of the present invention. In other words, the direction in which the seats are arranged in the chair device is the left-right or horizontal direction, and the depth direction is the front-rear direction. However, these terms are used for convenience of explanation and do not limit the technical scope of the present invention. In addition, the horizontal direction is used as a general term for the left-right or horizontal direction and the front-rear direction.

[0018] The chair device 1 as a combination piece of furniture shown in Fig. 1 comprises a parts unit 2 consisting of a selective combination of a square seat 4, a seat body with panel 5, and a seat body with opposing panel 6, and a base structure 3 that supports the parts unit 2. The square seat 4, the seat body with panel 5, and the seat body with opposing panel 6 are selectively combined as appropriate and attached to the base structure 3 side by side in the left-right direction (horizontal direction). The square seat 4, the seat body with panel 5, and the seat body with opposing panel 6 in the embodiment constitute the parts of the parts unit 2, but are not limited to seat-related items, and the concept also includes items such as tabletops.

[0019] 1 and 2, the square seat 4 is formed in a square shape in a plan view. In this specification, the terms square and rectangular are concepts that include shapes with rounded or chamfered corners.

[0020] As shown in Fig. 1 and Fig. 3, the panel-attached seat body 5 comprises a rectangular seat 7 whose long side is the same length as one side of the square seat 4, and a panel 9 erected on one of the long sides of the rectangular seat 7. A cushion body 10 protruding toward the front side is provided on the upper side of the surface of the panel 9 (the surface facing the rectangular seat 7). In other words, in this embodiment, a cushion panel 9b having a cushion body 10 is used as the panel 9 of the panel-attached seat body 5. The cushion panel 9b may be a plate-shaped panel 9a to which the cushion body 10 is attached separately (see Fig. 12(a)), or may be an integral part (see Fig. 3(b)).

[0021] As shown in Fig. 3, in this embodiment, a pair of connecting pieces 11 protruding in the same direction is provided on the lower end side of the cushion panel 9b. The cushion panel 9b is detachably attached to the rectangular seat 7 by overlapping the lower surface side of the cushion panel 9b with one of the long sides of the rectangular seat 7 and fastening the pair of connecting pieces 11 to the underside of the rectangular seat 7 from below with screws. The rectangular seat 7 and the cushion panel 9b attached to it constitute the panel-attached seat body 5. As is clear from the manner in which the cushion panel 9b is attached to the rectangular seat 7, the panel 9 of the panel-attached seat body 5 can be selected from a plate-shaped panel 9a (see Figs. 4(b) and 12(a)) and a cushion panel 9b (see Fig. 3(b)).

[0022] 1 and 4, the panel-attached seat body 6 is equipped with a small square seat 8 having four sides the same length as the short sides of the rectangular seat 7 and a similar shape to the square seat 4, and two panels 9 erected along two adjacent sides of the small square seat 8. In this embodiment, one panel 9 is a cushion panel 9b having the same structure as that of the panel-attached seat body 5. The other panel 9 is a plate-shaped panel 9a (see FIG. 4(b)).

[0023] As shown in FIG. 4, in the embodiment, a pair of connecting pieces 11 protruding in the same direction is also provided on the lower end side of the plate-shaped panel 9a. The lower surface sides of the plate-shaped panel 9a and the cushion panel 9b are overlapped with the two adjacent sides of the small square seat 8, and the pair of connecting pieces 11 are screwed from below to the lower surface side of the small square seat 8, so that the plate-shaped panel 9a and the cushion panel 9b are detachably attached to the small square seat 8. The plate-shaped panel 9a and the cushion panel 9b attached to the small square seat 8 constitute the paired panel seat body 6. As is clear from the mounting mode of the plate-shaped panel 9a and the cushion panel 9b to the small square seat 8, the panel 9 of the paired panel seat body 6 can also be selected from the plate-shaped panel 9a and the cushion panel 9b. As is clear from the above explanation, in this specification, the higher concept of the plate-shaped panel 9a and the cushion panel 9b is collectively called the panel 9.

[0024] As described above, the rectangular seat 7 of the panel seat body 5 has a long side with the same length D1 as one side of the square seat 4. The small square seat 8 of the counter panel seat body 6 has four sides with the same length as the short side D2 of the rectangular seat 7, and is similar in shape to the square seat 4. As shown in Fig. 5, the square seat 4, the panel seat body 5, and the counter panel seat body 6 are standardized by being configured in a square shape of the same size in a plan view. In other words, the panel seat body 5 has a square shape in a plan view with the panel 9 attached to the rectangular seat 7, and the four sides have the same length as one side D1 of the square seat 4.

[0025] In the embodiment, the side length L of the panels 9 of the panel seat body 5 and the counter panel seat body 6 is set to be the same. In this case, the side length L of each panel 9 is approximately the same as the length D1 of the long side of the rectangular seat 7 (which is also the length of one side of the square seat 4). Therefore, it is possible to standardize parts when manufacturing each panel 9.

[0026] In addition, when constructing the panel-attached seat body 6, the side length of one panel 9 may be the length D1 of the long side of the rectangular seat 7, and the side length of the other panel 9 may be the length D2 of the short side of the rectangular seat 7 (which is also the length of one side of the small square seat 8).

[0027] As shown in Figs. 6 and 7, the base structure 3 includes an underframe 12 having a rectangular frame shape in plan view, and four leg supports 13 supporting the four corners of the underframe 12. The underframe 12 includes a pair of long frames 12a and a pair of short frames 12b. The long frames 12a and the short frames 12b are both formed in a hollow angular shape. The adjacent long frames 12a and short frames 12b are detachably connected via L-shaped corner connectors 14 to form the underframe 12 having a rectangular frame shape in plan view. In the embodiment, the upper end side of the corresponding leg support 13 is detachably attached to each corner connector 14.

[0028] The square base 4, panel-attached base body 5, and counter-panel-attached base body 6 are configured so that the mounting orientation with respect to the base structure 3 can be changed in four horizontal directions (front, back, left, and right). A total of eight female screw holes 15 (mesh nuts) are provided on the underside of the square base 4, two along each side. These female screw holes 15 are positioned in a line-symmetrical relationship with four holes on each side of the diagonal line DI1 of the square base 4 in a plan view.

[0029] Further, eight female threaded holes 16 (mesh nuts) are provided on the underside of the rectangular seat 7 of the panel-mounted seat body 5, two on each side. These female threaded holes 16 are also arranged in a line-symmetrical relationship with four holes in each direction across the diagonal line DI2 of the panel-mounted seat body 5 in a plan view. Similarly, eight female threaded holes 17 (mesh nuts) are provided on the underside of the small square seat 8 of the panel-mounted seat body 6, two on each side. These female threaded holes 17 are also arranged in a line-symmetrical relationship with four holes in each direction across the diagonal line DI3 of the panel-mounted seat body 6 in a plan view.

[0030] The underframe 12 (long frame 12a and short frame 12b) has a plurality of insertion holes 18 formed at appropriate intervals along the longitudinal direction, which penetrate vertically and through which screws can be inserted. In the embodiment, six insertion holes 18 are formed in each of the long frames 12a, and two insertion holes 18 are formed in each of the short frames 12b.

[0031] The insertion holes 18 of the frame 12 are set to match the female threaded holes 15-17 of the square base 4, panel-mounted base body 5 or anti-panel base body 6 after the mounting orientation of the square base 4, panel-mounted base body 5 or anti-panel base body 6 placed on the frame 12 is changed to each of the four horizontal directions (front, back, left, and right).

[0032] 6 and 7, a total of six insertion holes 18, two on the right side of each long frame 12a and two on the right short frame 12b, match with six female threaded holes 15 of the square seat 4. Also, a total of four insertion holes 18, two on the center side of each long frame 12a, match with four female threaded holes 16 of the rectangular seat 7. And a total of six insertion holes 18, two on the left side of each long frame 12a and two on the left short frame 12b, match with six female threaded holes 17 of the small square seat 8.

[0033] With the square seat 4, panel-mounted seat body 5 or anti-panel seat body 6 placed on the frame 12 in a specified installation orientation, screws are screwed from below into the matching insertion holes 18 and female threaded holes 15-17, whereby the square seat 4, panel-mounted seat body 5 and anti-panel seat body 6 can be attached to the base structure 3 in four horizontal directions (front, back, left, and right) and can be detachably attached so that their installation orientation can be changed in four horizontal directions (front, back, left, and right).

[0034] In this case, as described above, the square seat 4, the panel seat body 5, and the paired panel seat body 6 are standardized to have the same size square shape in a plan view. Therefore, the panel seat body 5 and the paired panel seat body 6 can be attached to the base structure 3 as is without being hindered by the presence of the panel 9 even if the installation direction is changed.

[0035] For example, Fig. 8 shows plan views in which the mounting orientation of the panel-attached seat body 5 in the middle is changed from the state in Fig. 1. (a) is when the panel 9 is placed on the left side, (b) is when the panel 9 is placed on the front side, and (c) is when the panel 9 is placed on the right side. Fig. 9 shows plan views in which the mounting orientation of the panel-attached seat body 6 on the left side is changed from the state in Fig. 1. (a) is when the cushion panel 9b is placed on the left side and the plate-like panel 9a is placed on the front side, (b) is when the cushion panel 9b is placed on the front side and the plate-like panel 9a is placed on the right side, and (c) is when the cushion panel 9b is placed on the right side and the plate-like panel 9a is placed on the rear side.

[0036] With the above configuration, it is not necessary to diversify the types of seats 4 to 6 for each desired layout, so it is possible to flexibly meet various user needs while suppressing costs. Furthermore, by using the component unit 2 of the present invention, users seated next to each other can be separated by selecting the panel seat body 5 or the counter panel seat body 6, and it is easy to set it to have an appropriate level of closure so that others do not interfere with each other. In this respect, too, it is possible to flexibly meet user needs.

[0037] As an example of such a flexible layout, FIG. 10 shows a case where the square seat 4 at the right end in FIG. 1 is changed to a panel seat body 5, the left panel 9 (plate-shaped panel 9a) of the left end paired panel seat body 6 is omitted, and a cushion panel 9b is attached to the right side. FIG. 11 shows a case where the square seat 4 at the right end in FIG. 1 is changed to a panel seat body 5, the panel seat body 5 in the middle is changed to a paired panel seat body 6, and the paired panel seat body 6 at the left end is changed to a panel seat body 5. In FIG. 11, in the paired panel seat body 6 in the middle, a cushion panel 9b is arranged on the rear side of the rectangular seat 7, and a plate-shaped panel 9a is arranged on the right side of the rectangular seat 7. In FIG. 11, even if the panel seat body 5 at the right end is changed to the paired panel seat body 6 in FIG. 1 and the panel seat body 5 is left as it is, the same configuration will be obtained.

[0038] In the embodiment, when mounting the square seat 4, the panel seat body 5, or the paired panel seat body 6 on the underframe 12, a spacer 19 is interposed between the underframe 12 and the square seat 4, the panel seat body 5, or the paired panel seat body 6. Each spacer 19 is formed with an insertion hole 20 through which a screw passes.

[0039] Therefore, in the embodiment, with the square seat 4, the panel-mounted seat body 5 or the anti-panel seat body 6 arranged on the frame 12 in a predetermined mounting orientation, by screwing screws from below into the matching insertion holes 18, the insertion holes 20 of the spacer 19 and the female threaded holes 15-17, the square seat 4, the panel-mounted seat body 5 and the anti-panel seat body 6 can be attached to the base structure 3 in four horizontal directions (front, back, left, right, and four directions) and can be detachably attached so that their mounting orientation can be changed in four horizontal directions (front, back, left, and right).

[0040] For this reason, a gap is formed between the frame 12 and the component unit 2 (the square seat 4, the panel-equipped seat body 5, and the counter-panel-equipped seat body 6). The presence of this gap makes it possible to attach a table 21 to the frame 12 and to attach a receiving stay 23 capable of accommodating an outlet 22, etc. (see the two-dot chain line in FIG. 7).

[0041] In the embodiment, three types of seats, a square seat 4, a rectangular seat 7, and a small square seat 8, are used, but the present invention is not limited to these. For example, the four peripheral parts of the square seat 4 may be configured to be expandable and deformable, and then one side of the square seat 4 may be shrunk to erect a panel 9 to form a panel seat body 5, or two adjacent sides of the square seat 4 may be shrunk to erect two panels 9 to form a paired panel seat body 6. In this case, standardization is possible by configuring the square seat 4, the panel seat body 5, and the paired panel seat body 6 to have the same size square shape in a plan view by shrinking the part of the square seat 4 where the panel 9 is erected. Even when the four peripheral parts of the square seat 4 are configured to be expandable and deformable, the panel 9 of the panel seat body 5 and the paired panel seat body 6 can be selected from a plate panel 9a and a cushion panel 9b.

[0042] As mentioned above, the cushion panel 9b may be a plate-shaped panel 9a to which the cushion body 10 is attached separately (see FIG. 12(a)), or may be an integral part (see FIG. 3(b) and FIG. 4(b)). The same applies when the four peripheral parts of the square seat 4 are configured to be expandable and deformable. The height of the plate-shaped panel 9a and the cushion panel 9b is not limited to that of the embodiment, and a high height as shown in FIG. 12(b) can be used. FIG. 12(b) shows a high cushion panel 9b, but even a plate-shaped panel 9a without a cushion body 10 can be used with such a high height.

[0043] Furthermore, in the embodiment, the panel 9 is attached to the rectangular seat 7 and the small square seat 8, but this is not limited to the above. It is also possible to configure the panel-attached seat body 5 and the counter-panel seat body 6 in such a manner that the panel 9 and the seats 7, 8 are attached to the frame 12 of the base structure 3 by their respective fixing means, and to adopt a structure in which the square seat 4, the panel-attached seat body 5 and the counter-panel seat body 6 are configured to be square in shape of the same size when viewed in a plane, as in the embodiment, and standardized.

[0044] Next, the detailed structure of the base structure 3 will be described with reference to Figure 13 onwards. As described above, the base structure 3 includes an underframe 12 configured into a rectangular frame shape in plan view by connecting adjacent long frames 12a and short frames 12b, or connecting the short frames 12b together, via L-shaped corner connectors 14, and four leg supports 13 attached to the four corner connectors 14. Each of the frames 12a, 12b is formed into a hollow angular shape.

[0045] As shown in Figures 14 and 15, the corner connector 14 has a pair of fitting protrusions 31 that fit into the end openings of the frames 12a and 12b. Each fitting protrusion 31 has a screw hole 32 that opens up and down, while each frame 12a and 12b has a screw insertion hole 33 that opens up and down at both longitudinal ends. When the corresponding fitting protrusions 31 of the corner connector 14 are fitted into the end openings of the frames 12a and 12b, the screw holes 32 of each fitting protrusion 31 match with the screw insertion holes 33 of the frames 12a and 12b. In this state, the adjacent long frame 12a and short frame 12b are detachably fastened to each other via the corner connector 14 by screwing a screw into the screw hole 32 from above or below through the screw insertion hole 18.

[0046] A downward-opening leg attachment hole 34 is formed in the center of the corner connector 14. With the upper end of the leg support 13 fitted into the leg attachment hole 34, a screw is screwed in from above, whereby the leg support 13 is detachably fastened to the corner connector 14, which is the corner of the underframe 12.

[0047] Each fitting protrusion 31 also has a through hole 35 that opens in the horizontal direction. Corresponding to the through hole 35, horizontal screw insertion holes 36 are formed at both longitudinal ends of each frame 12a, 12b. It goes without saying that the through holes 35 of each fitting protrusion 31 and the screw insertion holes 36 of each frame 12a, 12b match with each other when the corresponding fitting protrusion 31 of the corner connector 14 is fitted into the end opening of each frame 12a, 12b. The through holes 35 of each fitting protrusion 31 and the screw insertion holes 36 of each frame 12a, 12b are for attaching an extension connector 37, which will be described later, to the underframe 12.

[0048] Now, block-shaped extension connectors 37 for connecting another base structure 3 can be attached to two horizontally outer corners of the underframe 12. The extension connector 37 has holding parts 38 for holding the underframe 12 on two opposing sides. The extension connector 37 has connecting screw holes 39 that open in the horizontal direction where both holding parts 38 are located.

[0049] The extension coupler 37 is held by the holding portion 38 of the extension coupler 37, the connecting screw hole 39 of the extension coupler 37 is aligned with the screw insertion hole 36 on the underframe 12 side, and a long screw from the inside of the underframe 12 is screwed into the connecting screw hole 39 of the extension coupler 37 via the screw insertion hole 36 of each frame 12a, 12b and the through hole 35 of each fitting protrusion 31, whereby the extension coupler 37 is detachably fastened to the corner portion of the underframe 12.

[0050] If the extension connector 37 did not have the holding portion 38, the load would be concentrated on the long screw, making it difficult for it to withstand the load. Therefore, in the embodiment, the holding portion 38 of the extension connector 37 regulates the relative displacement between the underframes 12, and the holding portion 38 bears the vertical load so that the long screw is not subjected to the vertical load. In addition, when the leg support 13 is attached to the extension connector 37 (details will be described later), the presence of the lower holding portion allows the extension connector 37 and the leg support 13 to bear the load in a distributed manner.

[0051] In the embodiment, block-shaped extension connectors 37 can be attached not only to each corner of the underframe 12 but also to two locations on the horizontal outside of the longitudinal midsection of each long frame 12a. In this case, horizontally opening screw insertion holes 36 are formed in two locations on the longitudinal midsection of each long frame 12a. The extension connectors 37 are detachably fastened to the two locations on the midsection of the long frames 12a of the underframe 12 by holding the underframe 12 with the holding portion 38 of the extension connector 37 and matching the screw insertion holes 40 of each long frame 12a with the connecting screw holes 39 of the extension connector 37, and screwing long screws from the inside of the underframe 12 into the connecting screw holes 39 of the extension connector 37 through the screw insertion holes 40 of each long frame 12a.

[0052] As shown in FIG. 13, the arrangement interval between adjacent screw insertion holes 36, 40 in each long frame 12a is set to the same DH as the arrangement interval between the screw insertion holes 36, 36 in each short frame 12b.

[0053] The extension connector 37 is formed with a leg attachment hole 41 that opens downward. With the upper end of the leg support 13 fitted into the leg attachment hole 41, a screw is screwed in from above, whereby the leg support 13 is detachably fastened to the extension connector 37. Therefore, each leg support 13 in the embodiment can be replaced with either the underframe 12 (corner connector 14) or the extension connector 37. In this manner, in the embodiment, not only each leg support 13 but also the long frame 12a, the short frame 12b, the corner connector 14, and the extension connector 37 are all identical in shape, and each part is standardized, which reduces the effort required for parts management and enables cost reduction.

[0054] As can be seen from the above description, in the embodiment, when a plurality of base structures 3 are connected in the horizontal direction, adjacent base structures 3, 3 can be connected by connecting the underframes 12 to each other via the extension connector 37. That is, adjacent base structures 3, 3 can connect the short frames 12b (short side sides) of the underframe 12 (main underframe) to each other via the extension connector 37, and can connect the long frames 12a (long side sides) of the underframe 12 (main underframe) to each other via the extension connector 37. Furthermore, the short frame 12b (short side side) of one underframe 12 (main underframe) and the long frame 12a (long side side) of the other underframe 12 (main underframe) can be connected to each other via the extension connector 37.

[0055] Fig. 16 shows a state in which the short frames 12b of the underframe 12 (main underframe) are connected to each other via two extension connectors 37, and two base structures 3 are connected in an I-shape. Fig. 17 shows a state in which the long frames 12a of the underframe 12 (main underframe) are connected to each other via two extension connectors 37, and two base structures 3 are connected in an island shape. Fig. 18 shows a state in which the short frame 12b of one underframe 12 (main underframe) is connected to the long frame 12a of the other underframe 12 (main underframe) via two extension connectors 37, and two base structures 3 are connected in an L-shape. Fig. 19 shows a state in which the short frames 12b of the underframes 12 (main underframes) are connected to each other via two extension connectors 37, and the short frame 12b of one underframe 12 (main underframe) is connected to the long frame 12a of the other underframe 12 (main underframe) via two extension connectors 37, resulting in three base structures 3 being connected in a T-shape. Note that illustration of the insertion holes 18 and screw insertion holes 33 in the underframes 12 is omitted in Figs. 16 to 19.

[0056] In this way, since the base structure 3 of the embodiment is itself standardized, various layouts can be created by combining them without diversifying the types. Therefore, various user needs can be flexibly responded to while suppressing costs. In particular, since various parts can be standardized, the labor of parts management can be reduced and costs can be reduced, which is a great advantage. For example, by standardizing both the base structure 3 (combination of the underframe 12) and the part unit 2 by 1 unit or 1.5 units, using the side direction length L of the panel 9 (which is also the length D1 of one side of the square seat 4) as a reference unit, there is an advantage that size variations can be easily narrowed down (consolidated) or expanded.

[0057] As an example of such a flexible layout of the base structure 3, a chair device 1 using the connection mode of the base structure 3 shown in Figs. 16 to 19 is shown in Figs. 20 to 22. Fig. 20 is an example of a chair device 1 using a pair of I-shaped connected base structures 3 shown in Fig. 16. In this example, from the right end, the component units 2 arranged in the order of a rearward facing paired panel seat body 6, two forward facing panel seat bodies 5, a forward facing paired panel seat body 6, a rearward facing panel seat body 5, and a rearward facing paired panel seat body 6 are mounted on the pair of I-shaped connected base structures 3. In the example shown in Fig. 20, the panels 9 of the panel seat body 5 and the paired panel seat body 6 are both high cushion panels 9b.

[0058] Fig. 21 shows an example of a chair device 1 using a pair of base structures 3 connected in an island shape as shown in Fig. 17. In this example, a parts unit 2 consisting of a total of six square seats 4 arranged in three columns in the left-right direction and two rows in the depth direction is mounted on the pair of base structures 3 connected in an island shape.

[0059] Fig. 22 is an example of a chair device 1 using a pair of L-shaped connected base structures 3 shown in Fig. 18. In this example, a component unit 2 using a pair of panel-equipped seat bodies 6 at the corners of the pair of base structures 3 and a panel-equipped seat body 5 for the remaining portion is mounted on the pair of L-shaped connected base structures 3. In the example shown in Fig. 22, the panels 9 of the panel-equipped seat body 5 and the panel-equipped seat body 6 are both cushion panels 9b of normal height.

[0060] As mentioned above, in the examples shown in Figures 20 to 22, each part of the part unit 2 can be appropriately selected and combined, for example, the square base 4, the panel-mounted base body 5, the opposing panel-mounted base body 6, or a tabletop or shelf of the same standard.

[0061] It is assumed that the base structure 3 of the embodiment will basically be sold as a set consisting of the underframe 12 and the four leg supports 13. As can be seen from Figures 20 to 22, when it is desired to add more base structures 3, by combining the underframe 12, two leg supports 13, and two extension connectors 37 into one set, it is possible to add more underframes 12 while keeping the number of leg supports 13 to a minimum, which is not only highly cost-effective but also very aesthetically pleasing in terms of design.

[0062] In addition, since each leg support 13 in the embodiment can be attached to either the underframe 12 (corner connector 14) or the extension connector 37, the leg support can be attached to the optimal position according to the layout, which is effective in improving the stability of the chair device 1 (furniture). If necessary, the leg support may be attached to both the underframe 12 (corner connector 14) and the extension connector 37, which will further increase stability.

[0063] 23 to 26 show an example in which a sub-frame 12' having a square shape in plan view and four sides with the same length as the short frame 12b is used in one of the adjacent base structures 3. As described above, the sub-frame 12' is different from the main frame in that it does not have the long frame 12a, but has the same basic structure, and the positions of the insertion holes 18 and the manner of connection with the extension connector 37 are configured in the same manner as the main frame 12. In FIGS. 23 to 26, the adjacent base structures 3, 3 are configured so that the short frame 12b (short side) of the main frame 12 and the short frame 12b of the sub-frame 12' can be connected via the extension connector 37. In FIG. 27, the adjacent base structures 3, 3 are configured so that the long frame 12a (long side) of the main frame 12 and the short frame 12b (one side) of the sub-frame 12' can be connected via the extension connector 37.

[0064] Fig. 23 shows a state in which the short frame 12b of the main underframe 12 and the short frame 12 of the sub-underframe 12' are connected via two extension connectors 37, and the base structure 3 of the main underframe 12 specifications and the base structure 3 of the sub-underframe 12' specifications are connected in an I-shape. Fig. 24 shows a state in which the short frame 12b of one main underframe 12 and the short frame 12b of the sub-underframe 12' are connected via two extension connectors 37, and the short frame 12b of the other main underframe 12 and the short frame 12b of the sub-underframe 12' specifications are connected in an L-shape.

[0065] Fig. 25 shows a state in which the short frames 12b of three main underframes 12 are respectively connected to the three short frames 12b of the sub-frame 12' via six extension connectors 37, and the three base structures 3 of the main underframe 12 specifications and the base structure 3 of the sub-frame 12' specifications are connected in a T-shape. Furthermore, Fig. 26 shows a state in which the short frames 12b of four main underframes 12 are connected to the four short frames 12b of the sub-frame 12' via eight extension connectors 37, and the four base structures 3 of the main underframe 12 specifications and the base structure 3 of the sub-frame 12 specifications are connected in a cross shape.

[0066] Fig. 27 shows a state in which the long frame 12a of the main underframe 12 and the short frame 12 of the sub-frame 12' are connected via two extension connectors 37, and the base structure 3 for the main underframe 12 and the base structure 3 for the sub-frame 12' are connected in an L-shape. Note that illustration of the insertion holes 18 and screw insertion holes 33 in the main underframe 12 and the sub-frame 12' is omitted in Figs. 23 to 27.

[0067] In this way, even when the base structure 3 of the main frame 12 specification and the base structure 3 of the sub-frame 12' specification are combined, various layouts can be created without diversifying the types. Therefore, it is possible to flexibly respond to various user needs while suppressing costs. It goes without saying that even in the example shown in Figures 23 to 27, the square seat 4, the panel seat 5, the counter panel seat 6, or a tabletop or shelf of the same standard can be appropriately and selectively combined and installed on each frame 12 as each part of the part unit 2.

[0068] 28 and 29 show an example of a chair device 1 using a base structure 3 with one main frame 12. In this example, a component unit 2 in which three paired panel seat bodies 6 are arranged side by side is mounted on the base structure 3. In the example of Figs. 28 and 29, the rear panel of the paired panel seat body 6 (which may be called a chair) is a high cushion panel 9b that functions as a backrest. Needless to say, the cushion panel 9b, which corresponds to the backrest, is a plate-like panel 9a (which may be called a plate-like body) to which a cushion body 10 is attached either separately or integrally.

[0069] A plate-shaped panel 9a (panel body) extending in the front-rear direction intersecting with the backrest surface of the cushion panel 9b (backrest) is disposed on one of the left and right sides of the small square seat 8 in each pair of panel-attached seat bodies 6. The cushion panel 9b (plate-shaped panel 9a portion) and the plate-shaped panel 9a on one of the left and right sides are set to the same height. It is also possible to provide a cushion body 10 on the surface of the plate-shaped panel 9a on one of the left and right sides (the surface facing the small square seat 8). The cushion body 10 may also be provided separately from or integrally with the plate-shaped panel 9a on one of the left and right sides.

[0070] The front side of each plate-shaped panel 9a opposite to the cushion panel 9b protrudes forward from the small square seat 8, and separates the adjacent paired panel seat bodies 6, 6. That is, in the example of Fig. 28 and Fig. 29, the side length La of the plate-shaped panel 9a is set longer than the side length L of the cushion panel 9b. In other words, each plate-shaped panel 9a has an extension 49 that protrudes forward from the front end of the small square seat 8. Although the extension 49 in the example of Fig. 28 and Fig. 29 is integrally formed with the plate-shaped panel 9a, it goes without saying that it may be formed separately. For example, if the extension 49 is formed of a plate material such as a transparent or translucent acrylic resin, it is possible to take measures against droplet infection without making the seated person feel a sense of obstruction, and it is easy to wipe and clean, and has excellent cleanability and anti-fouling properties.

[0071] In this case, if the side length L of the cushion panel 9b (which is also the length D1 of one side of the square seat 4) is taken as one unit of reference, the side length La of the plate-like panel 9a is, for example, a length equivalent to 1.5 units. Of course, the side length La of the plate-like panel 9a is not particularly limited as long as it is longer than the aforementioned one unit. For example, it is preferable that the side length La of the plate-like panel 9a is such that the legs below the knees of a person normally seated on each pair of panel-attached seat bodies 6 are covered. The left and right plate-like panels 9a and the end panel 9c are attached to the corresponding small square seat 8 in the same manner as described above (via a pair of connecting pieces 11). Therefore, the pair of panel-attached seat bodies 6 with the plate-like panels 9a and the end panels 9c can be attached to the base structure 3 as a unit. This makes it easy to carry out construction, dismantling, and reassembly.

[0072] Among the multiple seat bodies 6 with opposing panels, an end panel 9c with the same shape as the plate-like panel 9a is arranged on the other left or right side where the seat bodies 6 with opposing panels are not adjacent. Therefore, the cushion panel 9b (plate-like panel 9a portion) with a high height, the plate-like panel 9a on one side of the left or right side, and the end panel 9c are set to the same height. The side length Lc of the end panel 9c is also set to be longer than the side length L of the cushion panel 9b, and is a length equivalent to, for example, 1.5 units, similar to the side length La of the plate-like panel 9a. In other words, it can be said that the end panel 9c also has an extension 59 that protrudes forward from the front end of the small square seat 8. In the example of Figures 28 and 29, the extension 59 is integrally provided with the end panel 9c, similar to the plate-like panel 9a, but it may be configured separately. For example, if the extension 59 is also made of a plate material such as a transparent or translucent acrylic resin, it is possible to take measures against droplet infection without making the seated person feel a sense of obstruction, and it is easy to wipe and clean, and has excellent cleanability and anti-fouling properties.

[0073] The other configurations are the same as those described above. For example, in a state where at least one of the plurality of panel-attached seat bodies 6 has a plate-shaped panel 9a on one side, the widths in the front-rear and left-right directions in plan view are standardized to a predetermined dimension, except for the extension part 49 of one of the left and right plate-shaped panels 9a. In the example of Fig. 28 and Fig. 29, in a state where each panel-attached seat body 6 has a plate-shaped panel 9a on one side, the panel-attached seat body 6 is configured to have a square shape with equal widths in the front-rear and left-right directions in plan view. This point is as described above based on Fig. 5 and the like. With this configuration, each panel-attached seat body 6 can be laid out by changing the mounting direction, so that various user needs can be flexibly met while suppressing costs.

[0074] Even in the case of the above configuration, it is easy to set the appropriate level of closure so that it is difficult for others to interfere, and it is possible to flexibly respond to user needs. In particular, since each plate-like panel 9a and end panel 9c has extensions 49, 59 that protrude forward from the front end of the small square seat 8, the closure can be further improved and it is possible to provide a comfortable environment for the seated person. It blocks the line of sight of the person next to you and improves the sense of being enclosed, making it easier to relax and concentrate. In addition, it is possible to block the flying of droplets of the seated person between the adjacent pair of panel-attached seat bodies 6, 6, which is effective in preventing droplet infection of various viruses such as the new coronavirus and influenza.

[0075] In the example of Figures 28 and 29, the end panel 9c with the same shape as the plate panel 9a is arranged on the other left or right side of the multiple panel-attached seat bodies 6 that are not adjacent to each other, so that all panel-attached seat bodies 6 can provide a space with a high sense of closedness. In addition, since the high cushion panel 9b and the plate panel 9a and end panel 9c on one of the left and right sides are set to the same height, if these panels are set to a height that covers the head of the seated person, a space with a high sense of closedness can be more effectively secured in each panel-attached seat body 6, which contributes to creating an environment in which the seated person can feel comfortable. The cushion panel 9b and the plate panel 9a and end panel 9c on one of the left and right sides are lined up without any unevenness, giving a good appearance and providing the same effect of blocking the view of the surroundings from the side and back.

[0076] In particular, since each plate-like panel 9a is provided with an extension portion 49 that protrudes forward beyond the front end of the small square seat 8, this more effectively prevents splashes and the like from the seated person from flying between adjacent paired panel seat bodies 6, 6.

[0077] 30 to 32 show an example of a chair device 1 using a pair of I-shaped connected base structures 3. This example is a modified example of the one shown in Figs. 28 and 29, and in this example as well, a parts unit 2 in which three paired panel seat bodies 6 are arranged side by side is mounted on a pair of I-shaped connected base structures 3. The rear panel of the paired panel seat body 6 (which may be called a chair unit) is a high cushion panel 9b that functions as a backrest. Needless to say, the cushion panel 9b, which corresponds to the backrest, is a cushion body 10 attached separately or integrally to a plate-shaped panel 9a (which may be called a plate-shaped body).

[0078] 30 to 32, the pair of long frames 12a in each underframe 12 are made to have different lengths. In this case, if the side direction length L of the cushion panel 9b (which is also the length D1 of one side of the square seat 4) is taken as one reference unit, the length of the long frame 12a in one underframe 12 is set to a length equivalent to, for example, 2.5 units, and the length of the long frame 12a in the other underframe 12 is set to a length equivalent to, for example, 2 units. Therefore, on the pair of base structures 3 connected in an I-shape, component units for 4.5 units are mounted in the left-right direction.

[0079] In the example of Fig. 30 to Fig. 32, the side lengths L, La, and Lc of the high cushion panel 9b (plate-shaped panel 9a portion), one of the left and right plate-shaped panels 9a, and the end panel 9c are set to the same length, for example, a length equivalent to 1.5 units. Therefore, between the other left and right side of each small square seat 8 and the adjacent plate-shaped panel 9a or end panel 9c, a space of 0.5 units in the left and right direction is left. A top plate 50 on which luggage or the like can be placed is attached to the space. An outlet 51 is attached to each top plate 50. In other words, the end panel 9c is arranged on the other left and right side of the paired panel seat body 6 with the top plate 50 in between.

[0080] As in the examples of Figures 28 and 29, each of the left and right plate-shaped panels 9a has an extension 49 that protrudes forward from the front end of the small square seat 8. The extension 49 in the examples of Figures 30 to 32 is integral with the plate-shaped panel 9a, but it goes without saying that it may be configured separately. It can be said that the end panel 9c also has an extension 59 that protrudes forward from the front end of the small square seat 8. In the examples of Figures 30 to 32, the extension 59 is integral with the end panel 9c like the plate-shaped panel 9a, but it may be configured separately. In the examples of Figures 30 to 32, the extensions 49, 59 may also be made of a plate material such as a transparent or translucent acrylic resin, as in the examples of Figures 28 and 29. In this case, it is possible to take measures against droplet infection without making the seated person feel a sense of obstruction, and it is easy to wipe and clean, and it is also easy to clean and has excellent anti-fouling properties.

[0081] In the example of Fig. 30 to Fig. 32, for example, when at least one of the plurality of panel-attached seat bodies 6 has a plate-shaped panel 9a on one side, the width in the front-rear direction and the width in the left-right direction are standardized to a predetermined dimension in plan view, except for the extension part 49 of the left or right plate-shaped panel 9a. In the example of Fig. 30 to Fig. 32, when each panel-attached seat body 6 has a plate-shaped panel 9a on one side, the width in the front-rear direction is standardized to a predetermined dimension of 1 unit and the width in the left-right direction is standardized to a predetermined dimension of 1.5 units in plan view. Since 0.5 units of the width in the left-right direction is the top plate 50, in this case too, each panel-attached seat body 6 is configured in a square shape with equal widths in the front-rear direction and the left-right direction in plan view, except for the extension part 49, and it is possible to change the installation direction and lay out the layout. It goes without saying that even if the width in the left-right direction of each panel-attached seat body 6 (which may be called a chair) is standardized to 1.5 units, it is possible to change the installation direction and lay out the layout, although the orientation is limited to 180° increments.

[0082] In the example of Figs. 30 to 32, the plate-like panel 9a on one side of the left or right side is attached to the corresponding small square seat 8 in the same manner as described above (through a pair of connecting pieces 11). Therefore, the paired panel seat body 6 with the plate-like panel 9a can be attached to the base structure 3 as a unit. This makes it easy to carry out the construction, dismantling and reassembly work. The end panel 9c is attached to the base structure 3 (short frame 12b) through a fixing device (not shown). The end panel 9c, which is an option (non-standard) of the standardized paired panel seat body 6, is fixed separately to the base structure 3 so as not to impede the freedom of layout (changing the orientation of the component unit 2). Of course, it is also possible to adopt a configuration in which the end panel 9c is attached to the corresponding top plate 50 through a pair of connecting pieces 11 in the same manner as described above.

[0083] 30 to 32, a table 21 and a support stay 23 are attached to the underframe 12 in correspondence with each panel-attached seat body 6. A groove-shaped guide body 52 for accommodating wiring extending from, for example, an outlet 51 is provided downwardly on each support stay 23. A cushion body 10 is provided on the surface of one of the left and right plate-like panels 9a (the surface facing the small square seat 8). The other configurations are the same as those of the examples in FIGS. 28 and 29.

[0084] The configurations shown in the examples of Figures 30 to 32 also provide the same effects as those shown in Figures 28 and 29. For example, each plate-like panel 9a and end panel 9c has extensions 49, 59 that protrude forward from the front end of the small square seat 8, which further improves the closed-in feel and provides a comfortable environment for the seated person. It blocks the view of the person next to you and improves the sense of enclosure, making it easier to relax and concentrate. In addition, it is possible to block the flying of droplets from the seated person between the adjacent pair-panel seat bodies 6, 6, which is effective in preventing droplet infection of various viruses such as the new coronavirus and influenza.

[0085] The configuration of each part in the present invention is not limited to the illustrated embodiment, and can be modified in various ways without departing from the spirit of the present invention. For example, in each of the above-described embodiments, the panel-attached seat body 5 and the counter-panel seat body 6 are shown as being integrated with the seats 7, 8 and the panel 9, but it is also possible to directly fix each of the various parts to the base structure 3. In this case, the seats 7, 8 and the panel 9 are standardized as 1 unit, 1.5 units, etc., to increase the degree of freedom in layout, and it is possible to configure various layouts with the standardized (common) base structure 3. The underframe 12 may be formed by connecting the frames 12a, 12b to a frame shape by appropriate connecting means such as welding, without using the corner connectors 14. In this case, the leg mounting holes 34 may be formed directly in the frames 12a, 12b. Although an example in which the leg mounting holes 34, 41 are provided in the underframe 12 and the extension connector 37 has been shown, the mounting manner of the leg support 13 is not particularly limited, and the leg mounting portion may be made into a leg mounting hole or a leg mounting protrusion, and the design may be changed as appropriate.
