Description

[Technical Field]

[0001] The present invention relates to a furniture unit having a plurality of functional components such as a seat. [Background technology]

[0002] BACKGROUND ART As a chair unit used in waiting rooms and the like of public facilities, a chair unit having a plurality of seats attached to a beam member extending substantially horizontally is known (see, for example, Patent Document 1).

[0003] The chair unit described in Patent Document 1 has a beam member that extends in a substantially horizontal direction supported by multiple legs that contact the floor. Multiple chair bodies, each with a seat and a backrest, are attached to the beam member in a line in the direction in which the beam member extends. A table and armrests are also attached to the beam member adjacent to the sides of the chair. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 2016 / 063826 Summary of the Invention [Problem to be solved by the invention]

[0005] In the chair unit described in Patent Document 1, the chair body, table, and armrests are fixed in fixed positions relative to the beam members. For this reason, if the chair body, table, and armrests are designed to have a support form (height, inclination, etc.) that allows able-bodied people to use them in a relaxed manner, there is a concern that elderly people, pregnant women, etc. may have difficulty standing up from a seated position. In addition, not only in chair units such as these, but also in furniture units in which multiple functional components are fixed at fixed positions on a beam member, it is desirable to be able to change the support mode (height, inclination posture, etc.) of the multiple functional components according to the diverse needs of users.

[0006] SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a furniture unit that allows the support mode of a plurality of functional members to be changed according to the needs of the user. [Means for solving the problem]

[0007] In order to solve the above problems, a fixture unit according to one aspect of the present invention employs the following configuration. A furniture unit according to one aspect of the present invention is characterized by comprising: legs that contact the floor surface; a beam member that extends in a direction intersecting the vertical direction and is supported by the legs; a plurality of functional members that are arranged along the extension direction of the beam member and support loads from below by the beam member; and an auxiliary beam member that extends across the lower positions of the plurality of functional members and is detachably attached between the beam member and the plurality of functional members to change the support state of the plurality of functional members.

[0008] The above configuration makes it possible to change between a usage form in which auxiliary beam members are not attached between the beam member and the multiple functional members and a usage form in which auxiliary beam members are attached. In the usage form in which auxiliary beam members are attached between the beam member and the multiple functional members, it is possible to change the height, tilt position, etc. (support mode) of the multiple functional members compared to the usage form in which auxiliary beam members are not attached. In addition, since the auxiliary beam member extends across the lower positions of multiple functional components, adding one auxiliary beam member makes it possible to simultaneously change the support mode of multiple functional components. Therefore, when this configuration is adopted, it is possible to suppress an increase in the number of parts and to simplify the work of changing the support mode of the functional components.

[0009] It is desirable that the extension length of the auxiliary beam member be set to be substantially the same as the extension length of the beam member.

[0010] In this case, by attaching the auxiliary beam member, it becomes possible to simultaneously change the support mode of all the functional members.

[0011] The furniture unit may further comprise a clamping member that is positioned below the functional member, sandwiching the beam member between them, and clamps and fixes the beam member together with the functional member from above and below; when the auxiliary beam member is not in use, the functional member is fixed to the beam member by clamping the beam member from above and below between the functional member and the clamping member; and when the auxiliary beam member is in use, the functional member is fixed to the auxiliary beam member and the beam member by clamping the auxiliary beam member and the beam member from above and below between the functional member and the clamping member.

[0012] In this case, when the auxiliary beam member is not used, the beam member is sandwiched alone from above and below by the functional member and the clamping member. When the auxiliary beam member is used, the beam member is overlapped with the auxiliary beam member and the functional member and the clamping member sandwich both beam members from above and below. Therefore, a common clamping member can be used in both configurations in which the auxiliary beam member is used and configurations in which the auxiliary beam member is not used. Therefore, when this configuration is adopted, it is possible to minimize the addition of new parts when changing the support mode of the functional member.

[0013] When the auxiliary beam member is in use, a spacer may be interposed between the functional member and the clamping member.

[0014] In this case, when the auxiliary beam member and the beam member are clamped and fixed from above and below by the functional member and the clamping member with a spacer interposed between them, the functional member is stably fixed to the auxiliary beam member and the beam member. Therefore, when this configuration is adopted, it is possible to firmly fix the functional member in a predetermined position.

[0015] The spacer may be formed integrally with the auxiliary beam member.

[0016] In this case, there is no need to prepare multiple separate spacer parts when using the auxiliary beam member, which prevents an increase in the number of parts and makes it easier to change the support mode of the functional member.

[0017] The spacer may be provided with at least one of an inclined support portion that inclines the functional member downward or upward in the front compared to when the auxiliary beam member is not in use, and an offset support portion that offsets the functional member forward or backward compared to when the auxiliary beam member is not in use.

[0018] In this case, the inclination angle and the front-rear position of the functional member can be changed by the inclined support portion and the offset support portion of the spacer.

[0019] The auxiliary beam member may be provided with a wire accommodating portion therein for accommodating wires, and with a terminal attachment / detachment portion connected to the wires on its outer surface.

[0020] In this case, since the terminal detachable portion is provided on the outer surface of the long auxiliary beam member arranged above the beam member, the terminal detachable portion can be placed in an appropriate position for easy use. Also, in this configuration, since the wiring housing portion is provided inside the long auxiliary beam member, it is possible to easily route the wiring to the appropriate position.

[0021] At least one of the plurality of functional members may be a seat on which a user can sit.

[0022] In this case, when an auxiliary beam member is attached between the beam member and the seat body, it is possible to change the support mode (height, tilt position, etc.) of the seat body compared to when the auxiliary beam member is not attached. Therefore, when the furniture unit is used as a priority seat for elderly people, pregnant women, etc., attaching an auxiliary beam member between the beam member and the seat body makes it possible to raise the seat height of the seat body or tilt the seat forward. Therefore, when this configuration is adopted, attaching an auxiliary beam member can improve usability for elderly people, pregnant women, etc. [Effects of the Invention]

[0023] The fixture unit according to one aspect of the present invention includes an auxiliary beam member that extends across the lower positions of the plurality of functional members and is detachably attached between the beam member and the plurality of functional members to change the support mode of the plurality of functional members. Therefore, when the fixture unit according to this aspect is adopted, the support mode of the plurality of functional members can be changed according to the needs of the user.

[0025] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, embodiments of the present invention will be described with reference to the accompanying drawings. In the following embodiments, common parts are designated by the same reference numerals, and some overlapping descriptions will be omitted.

[0026] [First embodiment] Fig. 1 is a perspective view of a furniture unit 1 of this embodiment, and Fig. 2 is a side view of the furniture unit 1. Fig. 3 is a vertical cross-sectional view of part III of the furniture unit 1 in Fig. 1. The furniture unit 1 of this embodiment is a chair unit used in airport waiting rooms, etc. The furniture unit 1 can be changed between a first usage configuration shown in Figs. 1 to 3 and a second usage configuration shown in Figs. 4 to 7.

[0027] First, the configuration of the furniture unit 1 in the first usage mode shown in Figs. 1 to 3 will be described. As shown in Figures 1 to 3, the furniture unit 1 comprises a pair of legs 10 placed on the floor surface F, a beam member 11 spanning the pair of legs 10, a plurality (three) of chair bodies 12 (single chairs) supported and fixed to the beam member 11, and two armrests 13 supported and fixed to the beam member 11 between adjacent chair bodies 12. The furniture unit 1 also comprises an auxiliary beam member 40 (see Figures 4 to 7) for changing the configuration from a first usage configuration to a second usage configuration. In this embodiment, the plurality of chair bodies 12 and armrests 13 constitute functional members of the furniture unit 1.

[0028] The leg body 10 comprises a base support 14 extending vertically in a short distance, a pair of leg pillars 15 extending downward from the base support 14 in two branches, and an adjuster 16 attached to the lower end of each leg pillar 15. The base support 14 has a rectangular horizontal cross section. A substantially rectangular groove 17 that opens upward is formed on the upper surface of the base support 14. The groove 17 extends in the chair width direction, which will be described later. The groove 17 is designed to fit into the lower half region of the end of the beam member 11 in the extension direction.

[0029] The beam member 11 has a shape with a vertically long rectangular cross section that extends linearly. The beam member 11 is supported by the pair of legs 10 by fitting into each groove 17 at the top of each leg 10. The beam member 11 supported by the pair of legs 10 extends substantially horizontally in one direction (a direction intersecting the vertical direction). The beam member 11 is made of a highly rigid metal material in order to support the weight of multiple chair bodies 12 and seated occupants. All of the chair bodies 12 supported and fixed to the beam member 11 have the same structure.

[0030] The chair body 12 comprises a seat body 18 that supports the buttocks of the seated person, and a backrest 19 that supports the back of the seated person. The seat body 18 and the backrest 19 are interconnected by a frame portion (not shown). Cushion members covered with a covering material are attached to the upper surface of the seat body 18 and the front surface of the backrest 19 (the surface facing the upper surface of the seat body 18). Note that the structure of the seat body 18 and the backrest 19 is not limited to this, and for example, the outside of the frame portions of the seat body 18 and the backrest 19 may be covered with a resin such as urethane. In addition, in this embodiment, the chair body 12, which is a functional member, is configured to have a seat body 18 and a backrest 19, but the chair body 12 may also be configured as a single seat body 18 without a backrest 19.

[0031] Hereinafter, the side facing the front of the backrest will be referred to as the "front," and the opposite side will be referred to as the "rear." The direction perpendicular to the vertical and front-to-back directions will be referred to as the "chair width direction." In the appropriate locations on the drawings, there is an arrow UP pointing upward in the vertical direction, an arrow FR pointing forward in the front-to-back direction, and an arrow LH pointing forward and leftward in the chair width direction.

[0032] Connecting legs 20 protrude downward from the left and right side edges of the seat body 18. The lower region of each connecting leg 20 has a generally rectangular horizontal cross section. A generally rectangular groove 21 that opens downward is formed on the underside of the lower region of each connecting leg 20. The groove 21 extends along the width direction of the chair. The upper half region of the beam member 11 can be fitted into the groove 21.

[0033] The two chair bodies 12 arranged at both ends in the chair width direction have their outer connecting legs 20 fastened to the beam member 11 in cooperation with the base supports 14 of the corresponding left and right legs 10. Specifically, as shown in Fig. 2, the base supports 14 are fastened to the connecting legs 20 with a plurality of bolts 22 in a state in which the grooves 21 of the connecting legs 20 are fitted into the upper half region of the beam member 11 and the grooves 17 of the base supports 14 of the legs 10 are fitted into the lower half region of the beam member 11. One end of the chair width direction of the chair body 12 is fixed to the longitudinal end of the beam member 11 by the base support 14 and the connecting legs 20 sandwiching the beam member 11 from above and below.

[0034] The inner connecting legs 20 of the two chair bodies 12 and the left and right connecting legs 20 of the remaining chair bodies 12 are fastened to the beam member 11 in cooperation with connecting fittings 23 that are concave in front view. The connecting fittings 23 have a substantially rectangular horizontal cross section. A substantially rectangular groove 24 that opens upward is formed on the upper surface of the connecting fitting 23. The groove 24 extends along the width direction of the chair. The groove 24 is designed to fit into the lower half region of the beam member 11. As shown in FIG. 3 , the groove 21 of the connecting leg 20 is fitted into the upper half region of the beam member 11, and the groove 24 of the connecting fitting 23 is fitted into the lower half region of the beam member 11. In this state, the connecting fittings 23 are fastened to the corresponding connecting legs 20 with multiple bolts 22. The chair body 12 is fixed to the beam member 11 by sandwiching the beam member 11 between the connecting fittings 23 and the connecting legs 20 from above and below.

[0035] 1, the armrest 13 includes an armrest body 25 that has a rectangular frame shape in a side view, and a connecting leg 26 that protrudes downward from the lower end of the armrest body 25. An upper edge 25u of the armrest body 25 extends in the front-to-rear direction while sloping downward at a predetermined angle from the rear end toward the front. The upper surface of the upper edge 25u allows a user seated in the chair body 12 to rest their elbows or elbow tips.

[0036] The connecting leg 26 of the armrest 13 has substantially the same shape as the connecting leg 20 of the chair body 12. In Figure 3, the reference numerals of the corresponding parts of the armrest 13 are placed in parentheses. Like the connecting leg 20 of the chair body 12, the connecting leg 26 of the armrest 13 is fastened and fixed to the beam member 11 in cooperation with a connecting metal fitting 23. In other words, with the groove 24 of the connecting leg 26 fitted into the upper half region of the beam member 11 and the groove 24 of the connecting metal fitting 23 fitted into the lower half region of the beam member 11, the connecting metal fitting 23 is fastened and fixed to the connecting leg 26 with a plurality of bolts 22. In this embodiment, the base support 14 and the connecting fitting 23 of the leg 10, together with the functional parts, constitute a clamping member that clamps and fixes the beam member 11 from above and below. The base support 14 and the connecting fitting 23, which are the clamping members, are arranged below the functional parts (chair body 12, armrests 13) with the beam member 11 in between.

[0037] Next, the configuration of the furniture unit 1 in the second usage mode shown in Figs. 4 to 7 will be described. Fig. 4 is a perspective view of the furniture unit 1 in the second usage mode, and Fig. 5 is a partially cross-sectional side view of the furniture unit 1 in the second usage mode. Fig. 6 is a perspective view of the beam member 11 and the auxiliary beam member 40, and Fig. 7 is a vertical cross-sectional view of part VII of Fig. 4 of the furniture unit 1. The furniture unit 1 in the second usage form differs from the furniture unit 1 in the first usage form in that an auxiliary beam member 40 is added. The auxiliary beam member 40 is used by stacking it on the upper surface of the beam member 11, as shown in Figure 6. In this embodiment, the extension length of the auxiliary beam member 40 is set to be the same as the extension length of the beam member 11. The extension length of the auxiliary beam member 40 being "the same" as the extension length of the beam member 11 also includes cases where there is a dimensional difference of the order of tolerance.

[0038] The auxiliary beam member 40 comprises a beam main body 40a having a substantially rectangular cross section extending in one direction (the chair width direction), and a plurality of spacer pieces 45 (spacers) formed integrally on the side surfaces of the beam main body 40a in the front-to-rear direction (the chair front-to-rear direction). The beam main body 40a is formed so that its width in the front-to-rear direction (the chair front-to-rear direction) is substantially the same as that of the beam member 11. As shown in Figures 5 and 7, the beam main body 40a is placed on the upper surface of the beam member 11.

[0039] In this state, the recessed grooves 17 (see Figure 5) of the base support posts 14 of the legs 10 and the recessed grooves 24 (see Figure 7) of the connecting fittings 23 are fitted into the lower half region of the beam member 11. Also, the recessed grooves 21 (see Figures 5 and 7) of the connecting legs 20 of the chair body 12 and the recessed grooves 24 (see Figure 7) of the connecting legs 26 of the armrests 13 are fitted into the upper half region of the auxiliary beam member 40 (beam body 40a). The auxiliary beam member 40 extends across the lower positions of the three chair bodies 12 and two armrests 13 (multiple functional members), and is detachably attached between the beam member 11 and the multiple functional members (chair bodies 12 and armrests 13).

[0040] The spacer pieces 45 extend downward a predetermined distance from the lower region of the side surface of the beam main body 40a. The length of each spacer piece 45 in the chair width direction is equal to the length of the connecting fitting 23 and the base support 14 of the leg body 10 in the chair width direction. The spacer pieces 45 are arranged in pairs on the front and rear side surfaces of the beam main body 40a. Each spacer piece 45 has a bolt insertion hole 47 that penetrates in the vertical direction. A bolt 22A is inserted into the bolt insertion hole 47 to fasten the upper and lower components (the connecting leg 20 and the base support 14, and the connecting legs 20, 26 and the connecting fitting 23).

[0041] The spacer pieces 45 are provided at the following locations on the front and rear side surfaces of the beam main body 40a. (1) A position corresponding to the butt joint between the connecting leg 20 of the chair body 12 and the base support 14 of the leg body 10 (see FIG. 5). (2) A position corresponding to the butt joint between the connecting leg 20 of the chair body 12 and the connecting metal fitting 23 (see FIG. 7). (3) A position corresponding to the butt portion of the connecting leg 26 of the armrest 13 and the connecting fitting 23 (see FIG. 7).

[0042] The spacer pieces 45 arranged at the respective positions described above are interposed between the functional members (chair body 12, armrest 13) and the corresponding clamping members (base support 14, connecting metal fitting 23).

[0043] The lower half regions of both ends of the beam member 11 in the chair width direction are fitted into the recessed grooves 17 on the upper surfaces of the base supports 14 of the legs 10. In this state, the beam body 40a of the auxiliary beam member 40 is placed on the upper surface of the beam member 11. In this state, multiple chair bodies 12 and armrests 13 are installed on the upper surface of the beam body 40a.

[0044] As shown in Figure 5, the connecting legs 20 on one end of the chair bodies 12 at both ends have their grooves 21 fitted into the upper half regions of the beam bodies 40a. In this state, bolts 22A passing through the base support 14 of the leg body 10 and the front and rear spacer pieces 45 of the auxiliary beam member 40 are tightened into the connecting legs 20. As a result, one connecting leg 20 of the chair body 12, together with the base support 14, firmly sandwiches the beam member 11 and the auxiliary beam member 40 from above and below, and as a result, is fixed to the beam member 11 and the auxiliary beam member 40. The bolt 22A used in the second usage mode has a longer axial length than the bolt 22 used in the first usage mode.

[0045] 7, the connecting legs 20 on the other end side of the end chair bodies 12 and the connecting legs 20 of the central chair body 12 have their recessed grooves 21 fitted into the upper half regions of the beam body 40a. In this state, the connecting metal fittings 23 and the bolts 22A passing through the front and rear spacer pieces 45 of the auxiliary beam member 40 are tightened into the connecting legs 20. As a result, the connecting legs 20 of the chair body 12, together with the connecting metal fittings 23, firmly sandwich the beam member 11 and auxiliary beam member 40 from above and below, and as a result, are fixed to the beam member 11 and auxiliary beam member 40.

[0046] Similarly, the connecting leg 20 of the armrest 13 has the groove 21 fitted into the upper half region of the beam body 40a. In this state, the bolt 22A passing through the connecting fitting 23 and the front and rear spacer pieces 45 of the auxiliary beam member 40 is tightened into the connecting leg 20. As a result, the connecting leg 20 of the armrest 13 is fixed to the beam member 11 and the auxiliary beam member 40. In this embodiment, multiple spacer pieces 45 are distributed at multiple locations spaced apart in the longitudinal direction on the front and rear sides of the beam main body 40a, but it is also possible to provide one spacer piece 45 on each of the front and rear sides of the beam main body 40a so that they are continuous in the longitudinal direction.

[0047] As described above, the furniture unit 1 of this embodiment is provided with auxiliary beam members 40 that extend across the lower positions of multiple chair bodies 12 and armrests 13 (functional members) and are detachably attached between the beam members 11 and the chair bodies 12 and armrests 13. This allows for appropriate use between a mode in which the auxiliary beam members 40 are not attached between the beam members 11 and the chair bodies 12 and armrests 13, and a mode in which the auxiliary beam members 40 are attached. In other words, if the mode in which the auxiliary beam members 40 are not attached is the standard specification, adding the auxiliary beam members 40 to the furniture unit 1 of the standard specification makes it possible to raise the height of the top surface of the seat support 18 of the chair body 12 and the height of the upper edge 25u of the armrest body 25. Therefore, when the furniture unit 1 of this embodiment is adopted, the support mode of the multiple functional members can be changed according to the needs of the user.

[0048] Furthermore, in the furniture unit 1 of this embodiment, the auxiliary beam member 40 extends across the lower positions of multiple functional members (multiple chair bodies 12 and armrests 13), so the support mode of multiple functional members can be changed simultaneously by adding one auxiliary beam member 40. Therefore, when the furniture unit 1 of this embodiment is adopted, an increase in the number of parts can be suppressed and the work of changing the support mode of the functional members can be simplified.

[0049] In particular, in the furniture unit 1 of this embodiment, the extension length of the auxiliary beam member 40 is set to be the same as the extension length of the beam member 11. Therefore, by attaching one auxiliary beam member 40, the support mode of all functional members (all chair bodies 12 and armrests 13) can be changed simultaneously.

[0050] The furniture unit 1 of this embodiment is also provided with the base support 14 and the connecting fitting 23, which are clamping members that clamp and fix the beam member 11 together with the functional members (chair body 12, armrest 13) from above and below. When the auxiliary beam member 40 is not in use, the functional members (chair body 12, armrest 13) are fixed to the beam member 11 by clamping the beam member 11 from above and below between the functional member and the clamping members (base support 14, connecting fitting 23). When the auxiliary beam member 40 is in use, the functional members (chair body 12, armrest 13) are fixed to the auxiliary beam member 40 and the beam member 11 by clamping the auxiliary beam member 40 and the beam member 11 from above and below between the functional member and the clamping members (base support 14, connecting fitting 23). Therefore, in the furniture unit 1 of this embodiment, the common clamping members (base support 14, connecting fitting 23) can be used as is in both a configuration in which the auxiliary beam member 40 is used and a configuration in which the auxiliary beam member 40 is not used. Therefore, when the furniture unit 1 of this embodiment is adopted, it is possible to minimize the addition of new parts when changing the support mode of the functional member.

[0051] Furthermore, in the furniture unit 1 of this embodiment, when the auxiliary beam member 40 is in use, a spacer (spacer piece 45) is interposed between the functional member (chair body 12, armrest 13) and the clamping member (base support 14, connecting metal fitting 23). Therefore, when the clamping member (base support 14, connecting metal fitting 23) is fastened to the functional member (chair body 12, armrest 13) with bolt 22A, the upper surface of the clamping member and the lower surface of the functional member each abut against the spacer, making it possible to stably fix the functional member to the auxiliary beam member 40 and beam member 11. Therefore, when this configuration is adopted, it becomes possible to firmly fix the functional member at a predetermined position.

[0052] In particular, in this embodiment, since the spacer (spacer piece 45) is formed integrally with the auxiliary beam member 40, there is no need to prepare a plurality of separate spacer components when using the auxiliary beam member 40. Therefore, when the furniture unit 1 of this embodiment is adopted, it is possible to suppress an increase in the number of parts and to make it easier to change the support mode of the functional members.

[0053] The furniture unit does not necessarily have to include the seat body 18 (chair body 12) as a functional member. However, when at least one of the plurality of functional members is the seat body 18 (chair body 12) as in the furniture unit 1 of this embodiment, the following additional effect can be obtained. That is, in a usage mode in which the auxiliary beam member 40 is attached between the beam member 11 and the seat body 18, the height of the seat surface of the seat body 18 can be made higher than in a usage mode in which the auxiliary beam member 40 is not attached. Therefore, when the furniture unit 1 is used as a priority seat for use by elderly people, pregnant women, etc., attaching the auxiliary beam member 40 between the beam member 11 and the seat body 18 makes it possible for elderly people, pregnant women, etc. to easily stand up from a seated position. In particular, in this embodiment, by attaching the auxiliary beam member 40, the height of the armrest 13 is also increased, so that when elderly people, pregnant women, etc. stand up from a seated position, they can place their hands on the top surface of the armrest 13 at a high position and raise their hips more easily.

[0054] [Second embodiment] FIG. 8 is a vertical cross-sectional view of a main part of the furniture unit 101 of this embodiment. The furniture unit 101 of this embodiment differs from the first embodiment only in the structure of the auxiliary beam member 140, and the other parts have the same configuration. In this embodiment, the auxiliary beam member 140 does not have spacer pieces integrally formed with the beam body. The auxiliary beam member 140 has a rectangular cross section that extends linearly in one direction. The spacers 145 interposed between the functional member and the clamping member are provided as separate parts from the auxiliary beam member 140. Each spacer 145 has an insertion hole 147 through which the shank of the bolt 22A is inserted.

[0055] The furniture unit 101 of this embodiment has the same configuration as the first embodiment except that the spacer 145 is configured as a separate part from the auxiliary beam member 140. Therefore, the same basic effects as those of the first embodiment can be obtained.

[0056] However, in this embodiment, since the spacer 145 is separate from the auxiliary beam member 140, the structure of the auxiliary beam member 140 can be simplified and the manufacturing of the auxiliary beam member 140 can be made easier than that of the first embodiment.

[0057] [Third embodiment] FIG. 9 is a perspective view of some components of the furniture unit 201 of this embodiment. In the furniture unit 201 of this embodiment, another function is added to the auxiliary beam member 240 attached between the beam member and the plurality of functional members. A wiring accommodating section 58 for accommodating wiring 60 such as power lines and signal lines is provided inside the auxiliary beam member 240, which extends along the width direction of the chair. Furthermore, a terminal connector 62 (detachable terminal section) into which a terminal such as a USB terminal or a power terminal can be inserted is attached to a part of the side surface (external surface) of the auxiliary beam member 240 in the front-to-rear direction (chair front-to-rear direction). The terminal connector 62 is connected to a plurality of wiring 60 routed inside the wiring accommodating section 58 of the auxiliary beam member 240. The terminal connector 62 is installed on the side surface of the auxiliary beam member 240, for example, at a position between adjacent chair body sections. 9 denotes a terminal insertion port formed on the front surface of the terminal connector 62.

[0058] In the furniture unit 201 of this embodiment, the auxiliary beam member 240 is a member that is arranged so as to straddle the lower positions of multiple chair bodies 12, so that the terminal connector 62 can be arranged in an appropriate position that is easy to use. In addition, because the wiring housing portion 58 is provided inside the long auxiliary beam member 240, the wiring 60 can be easily routed to the appropriate position.

[0059] [Fourth embodiment] FIG. 10 is a vertical cross-sectional view of a main part of a furniture unit 301 of this embodiment. The basic configuration of the furniture unit 301 of this embodiment is almost the same as that of the second embodiment, but the structure of the spacer 245 interposed between the functional member (connecting legs 20, 26) and the clamping member (connecting fitting 23, base support) is different from that of the second embodiment.

[0060] The spacer 245 of this embodiment includes a lower wall 54 that abuts against the upper surfaces of the connecting fitting 23 and the base support of the leg, and an upper wall 55 that abuts against the lower surfaces of the chair body and the connecting legs 20, 26 of the armrest. The lower surface of the lower wall 54 is formed approximately horizontal, while the upper surface 55u of the upper wall 55 is inclined downward and forward at a predetermined angle. The upper wall 55 of the spacer 245, which is located behind the beam member 11 and auxiliary beam member 140, and the upper wall 55 of the spacer 245, which is located in front of the beam member 11 and auxiliary beam member 140, are arranged so that their upper surfaces 55u form a continuous plane. The lower wall 54 of the spacer 245 is fastened and fixed to the connecting fitting 23 and the base support of the leg by a bolt 22C. The upper wall 55 of the spacer 245 is fastened and fixed to the chair body and the connecting legs 20, 26 of the armrest by another bolt 22B.

[0061] When the connecting legs 20, 26 of the chair body and armrests are fastened to the upper wall 55 of the spacer 245 with the bolts 22B, the connecting legs 20, 26 are fixed to the spacer 245 in a forward tilted state because the upper surface 55u of the upper wall 55 is tilted downward and forward. Note that in Fig. 10, symbol L1 denotes the central axis of the beam member 11, and symbol L2 denotes the central axis of the auxiliary beam member 140. In this embodiment, the upper surface 55u of the upper wall 55 of the spacer 245 is inclined downward and forward, but the upper surface 55u of the upper wall 55 of the spacer 245 can also be inclined upward and forward. In this embodiment, the upper surface 55u of the upper wall 55 of the spacer 245 forms an inclined support portion. The inclined support portion inclines the functional members (chair body, armrests) downward and forward or upward and forward compared to when the auxiliary beam members 140 are not in use.

[0062] In the furniture unit 301 of this embodiment, the upper surface 55u of the upper wall of the spacer 245 is inclined. Therefore, when using the auxiliary beam member 140, not only the height of the functional member but also the inclination angle of the functional member in the front-to-back direction can be changed. Therefore, when the furniture unit 301 of this embodiment is adopted, the inclination angle of the chair body and armrests can be changed to suit the user's use. For example, changing the inclination angle so that the chair body and armrests are inclined downward and forward can assist the user sitting in the chair body when standing up. Furthermore, changing the inclination angle so that the chair body and armrests are inclined downward and backward allows the user to sit in the chair body more relaxed.

[0063] [Fifth embodiment] FIG. 11 is a vertical cross-sectional view of a main part of a furniture unit 401 of this embodiment. The basic configuration of the furniture unit 301 of this embodiment is almost the same as that of the second embodiment, but the structure of the spacer 345 is different from that of the second embodiment.

[0064] The spacer 345 of this embodiment includes a lower wall 54 that abuts against the upper surfaces of the connecting fittings 23 and the base support posts of the legs, and an upper wall 55 that abuts against the lower surfaces of the chair body and the connecting legs 20, 26 of the armrests. The lower surface of the lower wall 54 and the upper surface of the upper wall 55 are formed approximately horizontally. The lower wall 54 is fastened to the connecting fittings 23 and the base support posts of the legs with bolts 22C, and the upper wall 55 is fastened to the chair body and the connecting legs 20, 26 of the armrests with other bolts 22B. The front and rear side walls of each spacer 345 are provided with step portions 65 that offset the upper region forward relative to the lower region. Note that in FIG. 11, reference symbol L1 denotes the central axis of the beam member 11, and reference symbol L3 denotes the central axis of the auxiliary beam member 140.

[0065] In this embodiment, the upper region of the side wall of the spacer 345 is offset forward relative to the lower region, but the upper region of the side wall of the spacer 345 can also be offset rearward relative to the lower region. In this embodiment, the step portion 65 of the side wall of the spacer 345 and the top wall 55 form an offset support portion. The offset support portion offsets the functional components (chair body, armrests) forward or rearward compared to when the auxiliary beam member 140 is not in use.

[0066] In the furniture unit 401 of this embodiment, the upper region of the side wall of the spacer 345 is offset forward or backward relative to the lower region, so that in a usage mode using the auxiliary beam member 140, it is possible to change not only the height of the functional member but also the front-to-back position of the functional member. Therefore, when the furniture unit 401 of this embodiment is adopted, the chair body and armrests can be changed to front-to-back positions suitable for use by the user.

[0067] In the fourth embodiment, the spacer 245 is provided with an inclined support portion (inclined upper surface 55u), and in the fifth embodiment, the spacer 345 is provided with an offset support portion (step portion 65 and upper surface 55u). The spacer interposed between the base member and the functional member can also employ a combination of the inclined support portion and the offset support portion.

[0068] The present invention is not limited to the above-described embodiment, and various design modifications are possible within the scope of the present invention. For example, in the above-described embodiment, the furniture unit is provided with three chair bodies and two armrests, but the number of chair bodies and armrests is not limited to these and can be set arbitrarily.

[0069] In the above embodiment, the chair body (seat) and armrests are used as the functional components of the furniture unit, but the functional components are not limited to these. The functional components may be, for example, a table or the like.

[0070] Furthermore, in the above embodiment, the furniture unit includes a chair body and armrests, but the furniture unit may also be configured to include only a plurality of chair bodies (seat bodies). [Explanation of symbols]
