The square seat 4, the seat body 5 with a panel, and the seat body 6 with a counter panel 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 panel-attached seat 5, and the counter-panel-attached seat 6 of the embodiment constitute the parts of the component unit 2, but are not limited to those related to seats, and include, for example, a top plate. It is a concept.

As shown in FIGS. 1 and 2, the square seat 4 is formed into a square shape in plan view. In addition, in this specification, the words "square shape" and "rectangular shape" are concepts that include rounded or chamfered corners.

As shown in FIGS. 1 and 3, the seat body 5 with a panel includes 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. It is equipped with A cushion body 10 that protrudes toward the surface is provided on the upper side of the surface of the panel 9 (the surface facing the rectangular seat 7). That is, in the embodiment, a cushion panel 9b having a cushion body 10 is used as the panel 9 of the seat body 5 with a panel. The cushion panel 9b may be one in which the cushion body 10 is separately attached to the plate-like panel 9b (see FIG. 12(a)), or may be provided integrally (see FIG. 3(b)).

As shown in FIG. 3, in the embodiment, a pair of connecting pieces 11 that protrude in the same direction are provided on the lower end side of the cushion panel 9b. The cushion panel 9b can be attached to and removed from 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 screwing the pair of connecting pieces 11 to the lower surface of the rectangular seat 7 from below. Possibly installed. A seat body 5 with a panel is a rectangular seat 7 with a cushion panel 9b attached thereto. As is clear from the manner in which the cushion panel 9b is attached to the rectangular seat 7, the panel 9 of the paneled seat body 5 consists of a plate panel 9a (see FIGS. 4(b) and 12(a)) and a cushion panel 9b ( (see FIG. 3(b)).

As shown in FIGS. 1 and 4, the counter-panel seat 6 has four sides having the same length as the short side of the rectangular seat 7, and a small square seat 8 having a similar shape to the square seat 4, and a seat next to the small square seat 8. It is provided with two panels 9 erected along two matching sides. In the embodiment, one panel 9 is a cushion panel 9b having a structure common to that of the paneled seat body 5. The other panel 9 is a plate-like panel 9a (see FIG. 4(b)).

As shown in FIG. 4, in the embodiment, a pair of connecting pieces 11 that protrude in the same direction are also provided on the lower end side of the plate-like panel 9a. By overlapping the lower surfaces of the plate panel 9a and the cushion panel 9b on the two adjacent sides of the small square seat 8, and screwing the pair of connecting pieces 11 onto the lower surface of the small square seat 8 from below, A plate panel 9a and a cushion panel 9b are removably attached to the square seat 8. A plate panel 9a and a cushion panel 9b are attached to a small square seat 8 to form a seat body 6 with a pair of panels. As is clear from the manner in which the plate-like panel 9a and the cushion panel 9b are attached to the small square seat 8, the panel 9 of the counter-panel seat body 6 can also be selected from the plate-like panel 9a and the cushion panel 9b. be. As is clear from the above description, in this specification, the generic concept of the plate panel 9a and the cushion panel 9b is collectively referred to as the panel 9.

As mentioned above, the rectangular seat 7 of the paneled seat body 5 has a long side having the same length D1 as one side of the square seat 4. The small square seat 8 of the counter-panel seat 6 has four sides having the same length as the short side D2 of the rectangular seat 7, and has a similar shape to the square seat 4. As shown in FIG. 5, the square seat 4, the panel-attached seat body 5, and the panel-attached seat body 6 are standardized to have the same square shape in plan view. That is, the seat body 5 with a panel has a square shape in 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.

In the embodiment, the length L in the side direction of the panel 9 of the seat body 5 with a panel and the seat body 6 with a counter panel is set to be the same. In this case, the length L of each panel 9 in the side direction 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, when manufacturing each panel 9, it is possible to use common parts.

In configuring the seat body 6 with a pair of panels, the length of one panel 9 in the side direction is the length of the long side of the rectangular seat 7, and the length of the other panel 9 in the side direction is the length of the long side of the rectangular seat 7. The length of the side may be D2 (which is also the length of one side of the small square seat 8).

As shown in FIGS. 6, 7, and 23 to 27, the base structure 3 includes an underframe 12 that is rectangular in plan view, and four leg supports 13 that support the four corners of the underframe 12. It is equipped with The underframe 12 shown in FIGS. 6 and 7 is configured as a main underframe that is rectangular in plan view and includes a pair of long frames 12a and a pair of short frames 12b. Both the long frame 12a and the short frame 12b are formed into hollow square shapes. Adjacent long frames 12a and short frames 12b are removably connected via L-shaped corner connectors 14 to form an underframe 12 having a rectangular frame shape in plan view (main underframe having a rectangular shape in plan view). There is.

As shown in FIGS. 23 to 26, the underframe also includes a sub-underframe 12' which is square in plan view and whose four sides are the same length as the short side (short frame 12b) of the main underframe. The sub-frame 12' is formed by using four short frames 12b having a hollow square shape, and connecting the adjacent short frames 12b detachably to each other via L-shaped corner connectors 14. The sub-frame 12' differs from the main frame 12 in that it does not include the long frame 12a, and they basically have the same structure. In the embodiment, a combination of three of the square seat 4, the seat with a panel 5, or the seat with a pair of panels 6 can be attached to the underframe 12 (main underframe) shown in FIGS. 1 to 22. Only one of the square seat 4, the seat body 5 with a panel, or the seat body 6 with a pair of panels can be attached to the underframe 12'. Hereinafter, when the underframe 12 is simply referred to, it will be explained as a concept that includes both the main underframe 12 and the sub-underframe 12'. In the embodiment, the upper end side of the corresponding leg support 13 is detachably attached to each corner connector 14.

The square seat 4, the seat body 5 with a panel, and the seat body 6 with a pair of panels are configured so that the attachment direction to the base structure 3 can be changed in four horizontal directions (four directions: front, back, left, and right). On the lower surface side of the square seat 4, a total of eight female threaded holes 15 (hidden nuts) are provided, two on each side. Four of these female screw holes 15 are placed in a line-symmetrical positional relationship across each diagonal line DI1 in a plan view of the square seat 4.

Further, on the lower surface side of the rectangular seat 7 of the paneled seat body 5, there are provided two female threaded holes 16 along each side, a total of eight female threaded holes 16 (black nuts). These four female threaded holes 16 are also placed in a line-symmetrical positional relationship across each diagonal line DI2 in a plan view of the seat body 5 with panel. Similarly, on the lower surface side of the small square seat 8 in the counter-panel seat body 6, there are provided two female threaded holes 17 along each side, for a total of eight female threaded holes 17 (black nuts). These four female threaded holes 17 are also placed in a line-symmetrical positional relationship across each diagonal line DI3 in a plan view of the panel-attached seat body 6.

In the underframe 12 (the long frame 12a and the short frame 12b, or the four short frames 12b), a plurality of insertion holes 18 are formed at appropriate intervals along the longitudinal direction to penetrate in the vertical direction and allow screws to be inserted therethrough. ing. In the embodiment, six insertion holes 18 are formed in the long frame 12a and two insertion holes 18 are formed in the short frame 12b.

The insertion holes 18 of the underframe 12 are formed so that the mounting direction of the square seat 4, the seat body 5 with a panel, or the seat body 6 with a panel mounted on the underframe 12 is set in four horizontal directions (front, rear, left, and right directions). After modification, it is set to match the female threaded holes 15 to 17 of the square seat 4, the seat body 5 with a panel, or the seat body 6 with a counter panel.

In the embodiment shown in FIGS. 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, are inserted into six female screw holes 15 of the square seat 4, and two on the right side of the short frame 12b. Match. Further, a total of four insertion holes 18, two on the center side of each long frame 12a, match with four female screw holes 16 of the rectangular seat 7. 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 screw holes 17 of the small square seat 8.

With the square seat 4, the panel seat 5, or the counter-panel seat 6 placed on the underframe 12 in a predetermined mounting orientation, insert screws from below into the insertion holes 18 and female threaded holes 15 to 17 that match each other. By screwing, the square seat 4, the seat body 5 with a panel, and the seat body 6 with a counter panel can be attached to and removed from the base structure 3 by changing the mounting direction in four horizontal directions (front, rear, left, and right directions). can be attached to.

In this case, as described above, the square seat 4, the panel-attached seat body 5, and the counter-panel-attached seat body 6 are standardized to have the same square shape in plan view. Therefore, even if the mounting orientation of the panel-attached seat body 5 and the panel-attached seat body 6 is changed, the presence of the panel 9 does not become an obstacle, and the seat body 5 with a panel and the counter-panel seat body 6 can be attached to the base structure 3 as they are.

For example, FIG. 8 shows a plan view in which the mounting direction of the seat body 5 with a panel in the middle is changed from the state shown in FIG. 1. (a) shows the case where the panel 9 is placed on the left side, (b) shows the case where the panel 9 is placed on the front side, and (c) shows the case where the panel 9 is placed on the right side. FIG. 9 shows a plan view in which the mounting direction of the panel-attached seat body 6 on the left side is changed from the state shown 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, (c) is when the cushion panel 9b is placed on the right side, This is a case where the plate-like panel 9a is placed on the rear side.

With the above configuration, there is no need to diversify the types of seats 4 to 6 for each desired layout, so it is possible to flexibly meet various user needs while reducing costs. Furthermore, if the component unit 2 of the present invention is used, in order to separate users who are seated next to each other, it is only necessary to select the seat body 5 with a panel or the seat body 6 with a counter panel, so that it is difficult for others to interfere with the seat body 5. It can be easily set to have appropriate closedness. In this respect as well, it is possible to respond flexibly to user needs.

As an example of such a flexible layout, in FIG. 10, the square seat 4 at the right end in FIG. 9a) is omitted and a cushion panel 9b is attached to the right side. In addition, in FIG. 11, the square seat 4 at the right end in FIG. 6 is changed to a seat body 5 with a panel. In FIG. 11, in the middle panel-attached seat body 6, a cushion panel 9b is arranged on the rear side of the rectangular seat 7, and a plate-like panel 9a is arranged on the right side of the rectangular seat 7. In addition, in FIG. 11, even if the panel-attached seat body 5 at the right end is changed to the panel-attached seat body 6 of FIG. 1, and the panel-attached seat body 5 in the middle is left as is, substantially the same aspect will be obtained.

In addition, in the embodiment, when attaching the square seat 4, the panel-attached seat 5, or the panel-attached seat 6 to the underframe 12, the underframe 12, the square seat 4, the panel-attached seat 5, or the panel-attached seat 6 are mounted on the underframe 12. A spacer 19 is interposed between the body 6 and the body 6. Each spacer 19 is formed with an insertion hole 20 through which a screw passes.

Therefore, in the embodiment, with the square seat 4, the panel seat 5, or the opposite panel seat 6 arranged on the underframe 12 in a predetermined mounting orientation, the insertion holes 18 and the spacers 19 are inserted so that they match each other. By screwing screws into the holes 20 and female threaded holes 15 to 17 from below, the square seat 4, the panel seat 5, and the counter panel seat 6 can be installed in four horizontal directions ( It can be changed in four directions (front, rear, left and right) and is detachably attached.

Therefore, a gap is formed between the underframe 12 and the component unit 2 (the square seat 4, the panel-attached seat 5, and the panel-attached seat 6). Due to the existence of the gap, a mounting member made of a metal fitting or the like that is the same as or thinner than the spacer 19 can be attached to the underframe 12, for example, and a table 21 or the like as an optional member can be supported by the underframe 12 via the mounting member. It is now possible. Furthermore, due to the existence of the above-mentioned gap, it is also possible to span the receiving stay 23, which is an optional member capable of accommodating an outlet 22, etc., over the underframe 12, and to suspend other optional members (see Fig. 7).

Although three types of seats are used in the embodiment: a square seat 4, a rectangular seat 7, and a small square seat 8, the present invention is not limited to these. For example, after configuring the four peripheral parts of the square seat 4 to be expandable and deformable, one side of the square seat 4 may be contracted and a panel 9 may be erected to form the seat body 5 with a panel, or the seat body 5 with a panel may be constructed by The seat body 6 with a counter panel may be constructed by erecting two panels 9 with the two sides shortened. In addition, as an example of "configuring the four peripheral parts of the square seat 4 to be expandable and deformable", the cushions on the four peripheral parts of the square seat 4 are pressed and elastically deformed, and the thickness of the panel 9 is reduced in order to attach the panel 9. It is possible to adopt a structure such as configuring the square seat 4 so that it can be retracted (concave), or configuring the four peripheral parts with a bellows-like body that expands and contracts. In this case, by shrinking the portion of the square seat 4 on which the panel 9 is erected, the square seat 4, the seat body 5 with a panel, and the seat body 6 with a counter panel can be formed into a square shape of the same size in plan view. , it becomes possible to standardize. Even when the four peripheral parts of the square seat 4 are configured to be expandable and deformable, the panel 9 of the panel-attached seat body 5 and the counter-panel-attached seat body 6 can be selected from the plate-like panel 9a and the cushion panel 9b.

Further, as described above, the cushion panel 9b may be one in which the cushion body 10 is separately attached to the plate-like panel 9a (see FIG. 12(a)), or may be provided integrally (see FIG. 3(b)). ) and FIG. 4(b)). The same applies to the case where the four peripheral parts of the square seat 4 are configured to be expandable and contractible. The heights of the plate panel 9a and the cushion panel 9b are not limited to those in the embodiment, and a high height as shown in FIG. 12(b) can be adopted. Although the cushion panel 9b shown in FIG. 12(b) has a high height, even a plate-like panel 9a without a cushion body 10 can be used as a high-height cushion panel 9b. In the embodiment, the panel 9 is attached to the rectangular seat 7 or the small square seat 8, but the panel 9 and the seats 7, 8 are not limited to such an embodiment. The seat body 5 with a panel and the seat body 6 with a counter panel are constructed in such a manner that they are attached by their respective fixing means, and similarly to the embodiment, the square seat 4, the seat body 5 with a panel, and the seat body 6 with a panel panel are attached. It is also possible to adopt a structure that is standardized by forming squares of the same size in plan view.

Next, the detailed structure of the base structure 3 will be described with reference to FIG. 13 and subsequent figures. As mentioned above, the base structure 3 includes an underframe 12 configured to have a rectangular frame shape in plan view by connecting adjacent long frames 12a and short frames 12b or short frames 12b to each other via L-shaped corner connectors 14. and four leg supports 13 attached to four corner connectors 14. Each frame 12a, 12b is formed into a hollow square shape.

As shown in FIGS. 14 and 15, the corner connector 14 includes a pair of fitting protrusions 31 that fit into the end openings of each frame 12a, 12b. Each fitting protrusion 31 is formed with a screw hole 32 that opens upward and downward, while screw insertion holes 33 that open upward and downward are formed at both longitudinal ends of each frame 12a, 12b. . When the corresponding fitting protrusion 31 of the corner connector 14 is fitted into the end opening of each frame 12a, 12b, the screw hole 32 of each fitting protrusion 31 and the screw insertion hole 33 of each frame 12a, 12b are connected. matches. In this state, by screwing a screw into the screw hole 32 from above or below through the screw insertion hole 18, the adjacent long frame 12a and short frame 12b are removably fastened via the corner connector 14.

A leg mounting hole 34 with a downward opening is formed in the center of the corner connector 14. The leg support 13 is removably fastened to the corner connector 14, which is a corner portion of the underframe 12, by screwing in a screw from above while the upper end of the leg support 13 is fitted into the leg mounting hole 34.

Further, each fitting protrusion 31 is also formed with a through hole 35 that opens in the horizontal direction. Corresponding to the through holes 35, screw insertion holes 36 that open in the horizontal direction are formed at both ends of each frame 12a, 12b in the longitudinal direction. With the corresponding fitting protrusion 31 of the corner connector 14 fitted into the end opening of each frame 12a, 12b, the through hole 35 of each fitting protrusion 31 and the screw insertion hole 36 of each frame 12a, 12b are inserted. Needless to say, they match. The through hole 35 of each fitting protrusion 31 and the screw insertion hole 36 of each frame 12a, 12b are for attaching an extension connector 37, which will be described later, to the underframe 12.

Now, at each corner of the underframe 12, block-shaped extension connectors 37 for connecting another base structure 3 can be attached at two locations on the outside in the horizontal direction. Holding portions 38 for holding the underframe 12 are provided on two opposing sides of the extension connector 37, respectively. The extension connector 37 is formed with a horizontally opened connecting screw hole 39 in which both the holding parts 38 are located.

Hold the underframe 12 with the holding part 38 of the extension connector 37, align the connection screw hole 39 of the extension connector 37 with the screw insertion hole 36 on the underframe 12 side, and insert the screws into each frame 12a, 12b. By screwing a long screw from the inside of the underframe 12 into the connecting screw hole 39 of the extension connector 37 through the hole 36 and the through hole 35 of each fitting protrusion 31, an extension connector is attached to the corner part of the underframe 12. 37 is removably fastened.

If the extension connector 37 did not have the holding portion 38, the load would be concentrated on the long screw, making it difficult to withstand the load. Therefore, in the embodiment, the relative displacement between the underframes 12 is regulated by the holding part 38 of the extension connector 37, and the holding part 38 is used to prevent vertical loads from being applied to the long screws. It has a structure that allows it to receive Furthermore, when the leg support 13 is attached to the extension connector 37 (details will be described later), the presence of the lower holding part allows the extension connector 38 and the leg support 13 to distribute the load and receive it. .

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 outside in the horizontal direction, at the mid-length of each long frame 12a. In this case, screw insertion holes 37 opened in the horizontal direction are formed at two locations midway along the length of each long frame 12a. Hold the underframe 12 with the holding part 38 of the extension connector 37, align the connection screw hole 39 of the extension connector 37 with the screw insertion hole 40 of each long frame 12a, and insert the screw insertion hole of each long frame 12a. By screwing a long screw from the inside of the underframe 12 into the connecting screw hole 39 of the extension connector 37 through the screw 40, the extension connector 37 can be attached and detached to two locations in the middle of the long frame 12a of the underframe 12. It is concluded.

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

The extension connector 37 has a leg mounting hole 41 that opens downward. The leg support 13 is removably fastened to the extension connector 37 by screwing in a screw from above while the upper end side of the leg support 13 is fitted into the leg attachment hole 41. Therefore, each leg support 13 of the embodiment can be replaced with either the underframe 12 (corner connector 14) or the extension connector 37. In this embodiment, not only each leg support 3 but also the long frame 12a, the short frame 12b, the corner connector 14, and the extension connector 37 have the same shape, and each part is common. This makes it possible to reduce management effort and costs.

As can be seen from the above description, in the embodiment, when a plurality of base structures 3 are arranged horizontally, the adjacent base structures 3 are connected to the underframes 12 via the extension connectors 37. It is possible to connect them in series by connecting them. That is, the adjacent base structures 3, 3 can connect the short frames 12b (short sides) of the underframe 12 (main underframe) via the extension connector 37, and the extension connector 37 The long frames 12a (long side sides) of the underframe 12 (main underframe) can be connected to each other via. Furthermore, the short frame 12b (short side) of one underframe 12 (main underframe) and the long frame 12a (long side) of the other underframe 12 (main underframe) are connected via the extension connector 37. can be concatenated.

FIG. 16 shows a state in which the short frames 12b of the underframe 12 (main underframe) are connected via two extension connectors 37, and the 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 the two base structures 3 are connected in an island shape. In FIG. 18, the short frame 12b of one underframe 12 (main underframe) and the long frame 12a of the other underframe 12 (main underframe) are connected via two extension connectors 37, and two A state in which the base structures 3 are connected in an L-shape is shown. In FIG. 19, the short frames 12b of the underframe 12 (main underframe) are connected to each other through two extension connectors 37, and one of the underframes 12 (main underframe) is connected through two extension connectors 37. The short frame 12b of the main underframe 12 (main underframe) is connected to the long frame 12a of the other underframe 12 (main underframe), and as a result, three base structures 3 are connected in a T-shape. Note that in FIGS. 16 to 19, illustrations of the insertion hole 18 and the screw insertion hole 33 in the underframe 12 are omitted.

In this way, the base structure 3 of the embodiment can create various layouts by combining the structures without diversifying the types. Therefore, it is possible to flexibly respond to various user needs while reducing costs. In particular, since various parts can be standardized, the effort of parts management can be reduced, and costs can also be reduced.

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 the pair of I-shaped connected base structures 3 shown in FIG. 16. In this example, from the right end, there is a seat with a panel facing backward 6, a seat with two panels facing forward 5, a seat with a panel facing forward 6, a seat with a panel facing backward 5, and a seat with a panel facing backward. The component units 2 arranged in the order of 6 are mounted on a pair of I-shaped connected base structures 3. In the example shown in FIG. 20, the panels 9 of the panel-attached seat body 5 and the panel-attached seat body 6 are both high-height cushion panels 9b.

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

FIG. 22 is an example of a chair device 1 using the pair of L-shaped connected base structures 3 shown in FIG. 18. In this example, the component unit 2 uses the panel-attached seats 6 at the paired corner portions of the base structure 3 and the panel-attached seats 5 at the other portions, and the base structure 3 is connected in an L-shape. It is mounted on a pair of In the example shown in FIG. 22, the panels 9 of the panel-attached seat body 5 and the panel-attached seat body 6 are both cushion panels 9b of normal height.

In the examples shown in FIGS. 20 to 22, each part of the component unit 2 may be selected as appropriate, such as a square seat 4, a seat with a panel 5, a seat with a pair of panels 6, or a top plate or shelf of the same standard. As mentioned above, they can be combined.

It is assumed that the base structure 3 of the embodiment is basically sold as a set including the underframe 12 and the four leg supports 13. As can be seen from FIGS. 20 to 22, when it is desired to add more base structures 3, the underframe 12, two leg supports 13, and two extension connectors 37 can be combined into one set. The number of underframes 12 can be increased while suppressing the number of underframes 13 to the necessary minimum, which not only provides a high cost advantage but also a great appearance in terms of design.

In addition, each leg support 13 of the embodiment can be replaced with either the underframe 12 (corner connector 14) or the extension connector 37, so the leg support can be attached to an optimal position depending on the layout. This is effective in improving the stability of the chair device 1 (fixture). If necessary, leg supports may be attached to both the underframe 12 (corner connectors 14) and the extension connectors 37, in which case stability will be further increased.

FIGS. 23 to 26 show an example in which a sub frame 12' having a square shape in plan view and whose four sides are the same length as the short frame 12b is used in one of the adjacent base structures 3. As mentioned above, the sub-frame 12' is basically the same structure as the main frame except that it does not include the long frame 12a, and the position of the insertion hole 18 and the connection with the extension connector 37 are different from the main frame 12'. The underframe 12 is configured in the same manner as the main underframe. 23 to 26, in the adjacent base structures 3, 3, the short frame 12b (short side) of the main underframe 12 and the short frame 12b of the sub-underframe 12' are connected via an extension connector 37. It is now possible. In FIG. 27, the adjacent base structures 3, 3 have a long frame 12a (long side) of the main underframe 12 and a short frame 12b (one side) of the sub underframe 12' via an extension connector 37. Can be connected.

In FIG. 23, the short frame 12b of the main underframe 12 and the short frame 12 of the auxiliary underframe 12' are connected via two extension connectors 37, and the base structure 3 of the main underframe 12 specification and the auxiliary underframe are connected. A state in which the frame 12' base structure 3 is connected in an I-shape is shown. In FIG. 24, the short frame 12b of one main underframe 12 and the short frame 12 of the sub-frame 12' are connected via two extension connectors 37, and the other short frame 12b is connected via two extension connectors 37. The short frame 12b of the main underframe 12 and the short frame 12 of the sub-frame 12' are connected, and the two base structures 3 of the main frame 12 specification and the base structure 3 of the sub-frame 12' specification are connected. A state in which they are connected in an L shape is shown.

In FIG. 25, the short frames 12b of the three main underframes 12 are connected to the three short frames 12 of the sub-underframe 12' through six extension connectors 37, and three of the specifications of the main underframe 12 are shown. This figure shows a state in which two base structures 3 and a base structure 3 having a subframe 12' are connected in a T-shape. Furthermore, in FIG. 26, the short frames 12b of the four main underframes 12 are connected to the four short frames 12 of the sub-underframe 12' via eight extension connectors 37, and the specifications of the main underframe 12 are This shows a state in which four base structures 3 and a base structure 3 with a subframe 12 are connected in a cross shape.

In FIG. 27, the long frame 12a 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 specification and the sub-frame are connected. A state in which the base structure 3 having a frame 12' specification is connected in an L-shape is shown. Note that in FIGS. 23 to 27, illustrations of the insertion holes 18 and the screw insertion holes 33 in the main underframe 12 and the sub-underframe 12' are omitted.

In this way, even when the base structure 3 with the main underframe 12 specification and the base structure 3 with the subframe 12' specification are combined, various layouts can be created without diversifying the types so much. Therefore, it is possible to flexibly respond to various user needs while reducing costs. In the examples shown in FIGS. 23 to 27, each part of the component unit 2 is attached to each underframe 12, such as a square seat 4, a seat with a panel 5, a seat with a pair of panels 6, or a top plate or shelf of the same standard. Needless to say, they can be selectively combined and installed as appropriate.

Note that the configuration of each part in the present invention is not limited to the illustrated embodiment, and can be variously modified without departing from the spirit of the present invention. For example, the underframe 12 may be formed by connecting the frames 12a and 12b together in a frame shape using a suitable 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 is shown in which the leg mounting holes 34 and 40 are provided in the underframe 12 and the extension connector 37, the manner in which the leg support 13 is mounted is not particularly limited. It is possible to change the design as a protrusion as appropriate.
