Four of these female screw holes 16 are also arranged in a line-symmetrical positional relationship with each diagonal line DI2 in the plan view of the paneled seat body 5 interposed therebetween. Similarly, on the lower surface side of the small square seat 8 in the seat body 6 with a panel, a total of eight female screw holes 17 (demon nuts) are provided, two along each side. Four of these female screw holes 17 are also arranged in a line-symmetrical positional relationship with each diagonal line DI3 in the plan view of the seat body 6 with a panel in between.

The underframe 12 (long frame 12a and short frame 12b) is formed with a plurality of insertion holes 18 penetrating in the vertical direction through which screws are inserted at appropriate intervals along the longitudinal direction. 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 have the square seat 4, the seat with panel 5, or the seat with panel 6 mounted on the underframe 12 in four horizontal directions (four directions in front, back, left, and right). After being changed, it is set to match the female screw holes 15 to 17 of the square seat 4, the seat with panel 5, or the seat with panel 6.

In the embodiment shown in FIGS. 6 and 7, a total of six insertion holes 18 including two on the right side of each long frame 12a and two on the right side of the short frame 12b are six of the female screw holes 15 of the square seat 4. Match. Further, a total of four insertion holes 18 on the center side of each long frame 12a match the four female screw holes 16 of the rectangular seat 7. Then, a total of six insertion holes 18 including two on the left side of each long frame 12a and two on the left side of the short frame 12b match the six female screw holes 17 of the small square seat 8.

With the square seat 4, the seat with panel 5, or the seat with panel 6 arranged on the underframe 12 in a predetermined mounting direction, screws are inserted from below into the insertion holes 18 and the female screw holes 15 to 17 that match each other. By screwing, the square seat 4, the seat with panel 5, and the seat with panel 6 can be attached to and detached from the base structure 3 in four horizontal directions (four directions in front, back, left, and right). Attached to.

In this case, as described above, the square seat 4, the seat with panel 5, and the seat with panel 6 are standardized by being configured in a square shape having the same size in a plan view. Therefore, the panel-attached seat body 5 and the anti-panel-attached seat body 6 can be mounted on the base structure 3 as they are without the presence of the panel 9 obstructing even if the mounting direction is changed.

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

With the above configuration, it is not necessary to diversify the types of seats 4 to 6 for each desired layout, so that it is possible to flexibly meet various user needs while controlling costs. Further, by using the component unit 2 of the present invention, in order to separate the users who are seated next to each other, the seat body 5 with a panel or the seat body 6 with a panel may be selected so as not to be interfered with by others. It can be easily set to have an appropriate degree of closure (closeness). In this respect as well, it is possible to flexibly respond to user needs.

As an example of such a flexible layout, in FIG. 10, the square seat 4 at the right end in FIG. 1 is changed to the seat body 5 with a panel, and the left panel 9 (plate-shaped panel) in the seat body 6 with a pair of panels at the left end is shown. 9a) is omitted, and the cushion panel 9b is attached to the right side. Further, in FIG. 11, the square seat 4 at the right end in FIG. 1 is changed to the seat body 5 with a panel, the seat body 5 with a panel in the middle is changed to the seat body 6 with a panel, and the seat body with a panel at the left end is changed. 6 is changed to a seat body 5 with a panel. In FIG. 11, in the seat body 6 with a pair of panels in the center, the cushion panel 9b is arranged on the rear side of the rectangular seat 7, and the plate-shaped panel 9a is arranged on the right side of the rectangular seat 7. In addition, in FIG. 11, even if the rightmost paneled seating body 5 is changed to the anti-paneled seating body 6 of FIG. 1 and the center is left as the paneled seating body 5, substantially the same mode is obtained.

In the embodiment, when the square seat 4, the seat with panel 5, or the seat with panel 6 is mounted on the underframe 12, the underframe 12, the square seat 4, the seat with panel 5, or the seat with panel 6 is attached. 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, the square seat 4, the seat with panel 5, or the seat with panel 6 is arranged on the underframe 12 in a predetermined mounting direction, and the insertion holes 18 and the spacers 19 that match each other are inserted. By screwing screws into the holes 20 and the female screw holes 15 to 17 from below, the square seat 4, the seat with panel 5, and the seat with panel 6 are mounted in four horizontal directions with respect to the base structure 3 ( It can be changed in four directions (front, back, left and right) and can be attached and detached.

Therefore, a gap is formed between the underframe 12 and the component unit 2 (square seat 4, seat with panel 5, seat with panel 6). The presence of the gap makes it possible to attach the table 21 to the underframe 12 and the receiving stay 23 capable of accommodating the outlet 22 and the like (see the alternate long and short dash line in FIG. 7).

As the seats of the embodiment, three types of seats, a square seat 4, a rectangular seat 7, and a small square seat 8, are used, but the seats are not limited thereto. For example, after the four peripheral parts of the square seat 4 are configured to be expandable and deformable, one side of the square seat 4 is contracted to erect the panel 9 to form the seat body 5 with a panel, or the square seats 4 are adjacent to each other. The two panels 9 may be erected by shrinking the two sides to form the seat body 6 with a panel. 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 panel may be formed into a square shape having the same size in a plan view. , It becomes possible to standardize. Even when the four peripheral portions of the square seat 4 are configured to be stretchable and deformable, the panel 9 of the seat body 5 with a panel and the seat body 6 with a panel can be selected from the plate-shaped panel 9a and the cushion panel 9b.

Further, as described above, the cushion panel 9b may be a plate-shaped panel 9a to which the cushion body 10 is attached separately (see FIG. 12A), or may be integrally provided (FIG. 3 (b). ) And FIG. 4 (b)). The same applies when the four peripheral portions of the square seat 4 are configured to be stretchable 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. 12B can be adopted. Although the cushion panel 9b having a high height is shown in FIG. 12B, even a plate-shaped panel 9a having no cushion body 10 having such a high height can be adopted.

Further, in the embodiment, the panel 9 is attached to the rectangular seat 7 or the small square seat 8, but the present invention is not limited to this mode, and the panel 9 and the seats 7 and 8 are attached to the underframe 12 of the base structure 3. A seat body 5 with a panel and a seat body 6 with a panel are configured in a manner of being attached by each fixing means, and the square seat 4, the seat body with a panel 5, and the seat body with a panel 6 are attached as in the embodiment. It is also possible to adopt a structure that is standardized by forming a square shape of the same size in a plan view.

Next, the detailed structure of the base structure 3 will be described with reference to FIGS. 13 and later. As described above, the base structure 3 is formed in a rectangular frame shape in a plan view by connecting the long frame 12a and the short frame 12b or the short frames 12b adjacent to each other via the L-shaped corner connector 14. And four leg struts 13 attached to the four corner connectors 14. The frames 12a and 12b are formed in 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 the frames 12a and 12b. The fitting protrusions 31 are formed with screw holes 32 opened vertically, while the screw insertion holes 33 opened vertically are formed at both ends of the frames 12a and 12b in the longitudinal direction. .. In a state where 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 inserted. Matches. In this state, by screwing the 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 detachably fastened via the corner connector 14.

A leg mounting hole 34 having a downward opening is formed in the central portion of the corner connector 14. By screwing the screw from above with the upper end side of the leg support 13 fitted into the leg mounting hole 34, the leg support 13 is detachably fastened to the corner connector 14 which is the corner portion of the underframe 12.

Further, each fitting protrusion 31 is also formed with a through hole 35 opened in the horizontal direction. Then, corresponding to the through holes 35, screw insertion holes 36 opened in the horizontal direction are formed at both ends of the frames 12a and 12b in the longitudinal direction. With the corresponding fitting protrusions 31 of the corner connector 14 fitted into the end openings of the frames 12a and 12b, the through holes 35 of the fitting protrusions 31 and the screw insertion holes 36 of the frames 12a and 12b. Needless to say, they match. The through hole 35 of each fitting protrusion 31 and the screw insertion hole 36 of each of the frames 12a and 12b are for attaching the extension connector 37 described later to the underframe 12.

By the way, at each corner of the underframe 12, a block-shaped extension connector 37 for connecting another base structure 3 to the outside can be attached to two places on the outer side in the horizontal direction. Holding portions 38 for holding the underframe 12 are provided on the two side portions facing each other in the extension connector 37. The extension connector 37 is formed with a connecting screw hole 39 that is open in the horizontal direction and has both holding portions 38.

The underframe 12 is held by the holding portion 38 of the extension connector 37, the connecting screw holes 39 of the extension connector 37 are matched with the screw insertion holes 36 on the underframe 12 side, and the screws of the frames 12a and 12b are inserted. By screwing a long screw from the inside of the underframe 12 into the connecting screw hole 39 of the extension connecting tool 37 through the hole 36 and the through hole 35 of each fitting protrusion 31, the extension connecting tool is inserted into the corner portion of the underframe 12. 37 is detachably fastened.

If the extension connector 37 does not have the holding portion 38, the load will be concentrated on the long screw, and it will be difficult to withstand the load. Therefore, in the embodiment, the relative displacement between the underframes 12 is regulated by the holding portion 38 of the extension connector 37, and the vertical load is applied by the holding portion 38 so that the long screw is not loaded in the vertical direction. It is structured to receive. Further, when the leg support 13 is attached to the extension connector 37 (details will be described later), the load can be distributed and received by the extension connector 37 and the leg support 13 due to the presence of the lower holding portion. ..

In the embodiment, the block-shaped extension connector 37 can be attached not only to each corner of the underframe 12 but also to the longitudinal middle portion of each long frame 12a at two locations on the outer side in the horizontal direction. In this case, screw insertion holes 37 opened in the horizontal direction are formed at two locations in the middle of the longitudinal portion of each long frame 12a. The underframe 12 is held by the holding portion 38 of the extension connecting tool 37, the screw insertion hole 40 of each long frame 12a is matched with the connecting screw hole 39 of the extension connecting tool 37, and the screw insertion hole of each long frame 12a. By screwing the long screw from the inside of the underframe 12 into the connecting screw hole 39 of the extension connecting tool 37 via the 40, the extension connecting tool 37 can be attached to and detached from two places in the middle of the long frame 12a of the underframe 12. To be concluded.

As shown in FIG. 13, the arrangement interval of the screw insertion holes 36, 40 adjacent to each other 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.

The extension connector 37 is formed with a leg mounting hole 41 having a downward opening shape. By screwing the screw from above with the upper end side of the leg support 13 fitted into the leg mounting hole 41, the leg support 13 is detachably fastened to the extension connector 37. Therefore, each leg support 13 of the embodiment can be replaced with either the underframe 12 (corner connecting tool 14) or the extension connecting tool 37. As described above, in the embodiment, not only the leg columns 13 but also the long frame 12a, the short frame 12b, the corner connecting tool 14 and the extension connecting tool 37 have the same shape, and the parts are shared. It is possible to reduce the management effort and cost.

As can be seen from the above description, in the embodiment, in the case where a plurality of the base structures 3 are connected in the horizontal direction, the adjacent base structures 3, 3 are connected to each other via the extension connector 37. It is possible to connect them in a row by connecting them. That is, the adjacent base structures 3 and 3 can connect the short frames 12b (short side side) of the underframe 12 (main underframe) to each other via the extension connector 37, and the extension connector 37 The long frames 12a (long side side) of the underframe 12 (main underframe) can be connected to each other via the above.

It shows a state in which the base structures 3 are connected in an L shape. In FIG. 19, short frames 12b of the underframe 12 (main underframe) are connected to each other via two extension couplers 37, and one underframe 12 (main underframe) is connected via two extension couplers 37. The short frame 12b of the above and the long frame 12a of the other underframe 12 (main underframe) are connected, and as a result, the three base structures 3 are connected in a T shape. In addition, in FIGS. 16 to 19, the insertion hole 18 and the screw insertion hole 33 in the underframe 12 are not shown.

As described above, the base structure 3 of the embodiment can be combined to create various layouts without diversifying the types. Therefore, it is possible to flexibly respond to various user needs while controlling costs. In particular, since various parts can be standardized, there is a great merit that the labor of parts management can be reduced and the cost can be reduced.

As an example of such a flexible layout of the base structure 3, the 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 the chair device 1 using the pair of the base structures 3 of the I-shaped connection shown in FIG. In this example, from the right end, a rear-facing seat with a panel 6, a front-facing two-panel seat 5, a front-facing anti-panel 6, a rear-facing panel-attached seat 5, and a rear-facing anti-panel seat. The component units 2 arranged in the order of 6 are mounted on the pair of the base structure 3 of the I-shaped connection. In the example shown in FIG. 20, the panel 9 of the seat body 5 with a panel and the seat body 6 with a panel is a cushion panel 9b having a high height.

It is mounted on the pair of. In the example shown in FIG. 22, the panel 9 of the seat body 5 with a panel and the seat body 6 with a panel is a cushion panel 9b having a normal height.

Also in the examples shown in FIGS. 20 to 22, as each component of the component unit 2, for example, a square seat 4, a seat with a panel 5, a seat with a panel 6, or a top plate or a shelf of the same standard is appropriately selected. As described above, they can be combined in a specific manner.

It is assumed that the base structure 3 of the embodiment is basically sold as a set of the underframe 12 and the four leg columns 13. As can be seen from FIGS. 20 to 22, when it is desired to add the base structure 3, the leg struts are formed by combining the underframe 12, the two leg struts 13 and the two extension connecting members 37 into one set. The underframe 12 can be added while suppressing the number of 13 to the minimum necessary, which not only has a high cost merit, but also has a very good appearance in terms of design.

Further, since each leg support 13 of the embodiment can be replaced with either the underframe 12 (corner connecting tool 14) or the extension connecting tool 37, the leg support can be attached at the optimum position according to the layout. It is effective in improving the stability of the chair device 1 (furniture). If necessary, leg struts may be attached to both the underframe 12 (corner connector 14) and the extension connector 37, in which case the stability will be further increased.

23 to 26 show an example in which a square-shaped subframe 12'in a plan view having the same length as the short frame 12b is used in one of the adjacent base structures 3. As described above, the sub-underframe 12'has basically the same structure as the main underframe except that it does not have the long frame 12a. The mode and the like are also configured as the underframe 12 in the same manner as the main underframe. In FIGS. 23 to 26, in the adjacent base structures 3 and 3, the short frame 12b (short side side) of the main frame 12 and the short frame 12b of the sub frame 12'are connected via the extension connector 37. It is possible. In FIG. 27, the adjacent base structures 3 and 3 have a long frame 12a (long side side) of the main frame 12 and a short frame 12b (one side side) of the sub frame 12'via the extension connector 37. It can be connected.

In FIG. 23, the short frame 12b of the main frame 12 and the short frame 12b of the sub frame 12'are connected via two extension couplers 37, and the base structure 3 and the sub table of the main frame 12 specifications are connected. It shows a state in which the base structure 3 of the frame 12'specification is connected in an I shape. In FIG. 24, the short frame 12b of one main frame 12 and the short frame 12b of the sub frame 12'are connected via two extension couplers 37, and the other is connected via two extension couplers 37. By connecting the short frame 12b of the main frame 12 and the short frame 12b of the sub frame 12', the two base structures 3 of the main frame 12 specification and the base structure 3 of the sub frame 12' specification are connected. It shows a state of being connected in an L shape.

In FIG. 25, the short frames 12b of the three main underframes 12 are connected to the three short frames 12b of the sub-underframe 12'via six extension couplers 37, respectively, and the three main underframe 12 specifications are shown. It shows a state in which one base structure 3 and a base structure 3 of the subframe 12'specification are connected in a T shape. Further, in FIG. 26, the short frames 12b of the four main underframes 12 are connected to the four short frames 12b of the sub underframe 12 ′ via eight extension couplers 37, and the main underframe 12 specifications are shown. It shows a state in which the four base structures 3 and the base structure 3 of the subframe 12 specifications are connected in a cross shape.

In FIG. 27, the long frame 12a of the main frame 12 and the short frame 12b of the sub frame 12'are connected via two extension couplers 37, and the base structure 3 and the sub table of the main frame 12 specifications are connected. It shows a state in which the base structure 3 of the frame 12'specification is connected in an L shape. In addition, in FIGS. 23 to 27, the insertion hole 18 and the screw insertion hole 33 in the main underframe 12 and the sub underframe 12'are not shown.

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 significantly diversifying the types. Therefore, it is possible to flexibly respond to various user needs while controlling costs. Also in the examples shown in FIGS. 23 to 27, as each component of the component unit 2 on each underframe 12, for example, a square seat 4, a seat with a panel 5, a seat with a panel 6, a top plate or a shelf of the same standard, etc. Needless to say, it can be installed in combination as appropriate.

The configuration of each part in the present invention is not limited to the illustrated embodiment, and various changes can be made without departing from the spirit of the present invention. For example, the underframe 12 may be one in which the frames 12a and 12b are connected in a frame shape by an appropriate connecting means such as welding without using the corner connecting tool 14. In this case, the leg mounting holes 34 may be formed directly in the frames 12a and 12b. An example is shown in which the leg mounting holes 34 and 41 are provided in the underframe 12 and the extension connector 37, but the mounting mode of the leg support 13 is not particularly limited, and the leg mounting portion may be a leg mounting hole or a leg mounting. The protrusions can be changed as appropriate in terms of design.
