Description

[Technical Field]

[0001] The present invention relates to a furniture system. [Background technology]

[0002] BACKGROUND ART Chairs are known in offices, public facilities, and the like, in which a chair body having a seat is attached to a support rod that extends substantially horizontally (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2016 / 063826 Summary of the Invention [Problem to be solved by the invention]

[0004] Such chairs are used by a wide variety of people, and therefore may require a variety of configurations.

[0005] Therefore, an object of the present invention is to provide a fixture system that can be modified in various ways. [Means for solving the problem]

[0006] (1) A fixture system according to one aspect of the present invention comprises a leg body installed on a floor surface, a support rod supported by the leg body and extending in the left-right direction, a seat supported by the support rod, and a connecting member between the leg body and the support rod that is detachably attached to each of the leg body and the support rod and is configured to be able to change the relative positional relationship between the leg body and the support rod, and is configured to be switchable between a first state in which the leg body and the support rod are connected without the connecting member, and a second state in which the leg body and the support rod are connected via the connecting member. According to this aspect, when switched to the first state, the support rod is connected to the leg body without the connecting member. On the other hand, when switched to the second state, the support rod is connected to the leg body via the connecting member. Therefore, it is possible to provide a furniture system that can be changed into various forms.

[0007] (2) In the above aspect (1), the device may be configured to be switchable between a third state in which the leg body and the support rod are connected via a connecting member different from that in the second state, and a fourth state in which the leg body and the support rod are connected via a connecting member different from that in the third state. According to this aspect, when switched to the third state, the support rod is connected to the leg via a connecting member different from that in the second state. On the other hand, when switched to the fourth state, the support rod is connected to the leg via a connecting member different from that in the third state. Therefore, it is possible to change to various other forms.

[0008] (3) In the above aspect (1) or (2), the support rod may be configured to be able to change its vertical position relative to the leg by switching between the first state and the second state. According to this aspect, the height of the support rod relative to the leg can be changed. When the support rod is set higher than a predetermined height relative to the leg, the seat becomes higher, which helps the occupant stand up. On the other hand, when the support rod is set lower than a predetermined height relative to the leg, the seat becomes lower, which is suitable for people who want to sit comfortably.

[0009] (4) In the aspect (2) above, when viewed from the left-right direction, the support rod may be configured so that the inclination of the support rod relative to the leg can be changed by switching between the first state and the third state. According to this aspect, the inclination of the support rod relative to the leg can be changed to either forward or backward. When the support rod is tilted forward relative to the leg, the seat surface tilts forward, which helps the occupant stand up. On the other hand, when the support rod is tilted backward relative to the leg, the seat surface tilts backward, which is suitable for people who want to sit deeply when sitting.

[0010] (5) In the above aspect (2) or (4), the support rod may be configured to be able to change its position in the front-rear direction relative to the leg by switching between the first state and the fourth state. According to this aspect, by changing the front-to-rear position of the support rod relative to the leg, it is possible to further change the configuration in various ways.

[0011] (6) In any of the above aspects (1) to (5), the connecting members may be disposed on both sides of the support rod in the left-right direction. According to this aspect, the support rod can be stably supported at both ends.

[0012] (7) In any of the above aspects (1) to (6), the leg body may be provided with a leg-side recess that is recessed downward and into which the support rod can be fitted, the connecting member may include a connecting main body portion that is arranged between the leg body and the support rod, the lower surface of the connecting main body portion may be provided with a connecting-side convex portion that protrudes downward and can be fitted into the leg-side recess, and the upper surface of the connecting main body portion may be provided with a connecting-side recess that is recessed downward and into which the support rod can be fitted. According to this aspect, when connecting without a connecting member, the support rod is fitted into the leg-side recess, thereby firmly connecting the leg to the support rod. On the other hand, when connecting via a connecting member, the connecting-side protrusion is fitted into the leg-side recess, and the support rod is fitted into the connecting-side recess, thereby firmly connecting the connecting member to each of the leg and the support rod.

[0013] (8) In the above aspect (7), the connecting side convex portion may be fitted into the leg side recess, the support rod may be fitted into the connecting side recess, and the leg body may be fixed to the support rod by being tightened and fixed to the seat via the connecting member. According to this aspect, with the connecting side convex portion engaged with the leg side recess and the support rod engaged with the connecting side recess, the leg body is tightened and fixed to the seat via the connecting member, thereby firmly fixing the leg body, connecting member and seat to the support rod.

[0014] (9) In the above aspect (7), the leg body may be fastened to the connecting member with the connecting side convex portion engaged with the leg side concave portion, and the connecting member may be fastened to the support rod by fastening to the seat with the support rod engaged with the connecting side concave portion. According to this aspect, the leg body is tightened and fixed to the connecting member with the connecting side convex portion fitted into the leg side concave portion, and the connecting member is tightened and fixed to the seat with the support rod fitted into the connecting side concave portion, thereby firmly fixing the leg body, connecting member and seat to the support rod.

[0015] (10) In any of the above aspects (1) to (9), the seat may be provided in plurality and arranged side by side in the left-right direction. According to this aspect, the relative positional relationships between the multiple seats and the legs can be changed by attaching and detaching the connecting members. Therefore, by adding a small number of members, the relative positions of all the seats relative to the legs can be changed all at once.

[0016] (11) In any of the above aspects (1) to (10), optional components may be further provided that are arranged side by side in the left-right direction of the seat in a plan view and supported by the support rod. According to this aspect, the relative positional relationship between the optional component and the leg body can be changed together with the seat by attaching and detaching the connecting component. Therefore, by adding only a few components, the relative positions of the seat and the optional component relative to the leg body can be changed all at once. [Effects of the Invention]

The leg connector 22 is configured to be connectable to the left and right ends of the support rod 20. The front ground rod 23 extends linearly downward and forward from the leg connector 22 in a side view. The rear ground rod 24 extends linearly downward and rearward from the leg connector 22 in a side view. The front ground rod 23 and the rear ground rod 24 extend such that the front-to-rear distance between their respective inner edges in the front-to-rear direction increases as they extend downward in a side view. The lower ends of the front ground rod 23 and the rear ground rod 24 contact the floor surface F.

[0025] The leg body 21 is provided with a leg-side recess 21d that is recessed downward and into which the support rod 20 can be fitted. In the example shown in the figure, the leg-side recess 21d is recessed downward from the upper surface of the leg connecting part 22. A pair of front and rear wall parts of the leg connecting part 22 (boundary parts with the front ground rod 23 and the rear ground rod 24) are formed with bolt insertion holes 22h that penetrate in the vertical direction.

[0026] <Support rod> The support rod 20 is supported by the leg body 21. The support rod 20 extends in the left-right direction. The support rod 20 is made of, for example, a metal material. Note that the support rod 20 only needs to be made of a material with high strength and rigidity, since it must support the weight of the seat 30, optional member 4, and seated person. The material from which the support rod 20 is made can be changed according to design specifications.

[0027] The support rod 20 is formed into a rectangular cross section that extends linearly in the left-right direction. When viewed from the left-right direction, the support rod 20 is formed into a rectangular shape that is long in the up-down direction. Legs 21 are attached to multiple points in the longitudinal direction of the support rod 20. The legs 21 are provided on both sides of the support rod 20 in the left-right direction. The support rod 20 is placed on the floor surface F via the legs 21.

FIG. 10 is a side view showing the first state of the furniture system 1, including a cross section XX of FIG. 9. FIG. 11 is a side view showing a second state of the furniture system 1 of the embodiment. FIG. 12 is a side view showing the second state of the furniture system 1, including a cross section corresponding to FIG. 10. FIG. 13 is a side view showing a fourth state of the furniture system 1 of the embodiment. Referring also to Figures 7 to 13, the furniture system 1 is configured to be switchable between a first state (see Figure 10) in which the leg body 21 and the support rod 20 are connected without the connecting member 107, and a second state (see Figure 12) in which the leg body 21 and the support rod 20 are connected via the connecting member 107.

[0050] The example in Figure 10 shows the case where the furniture system 1 is switched to the first state. In the first state, the support rod 20 is connected to the leg 21 without the connecting member 107. In the first state, the upper part of the support rod 20 is fitted into the seat-side recess 30d, and the lower part of the support rod 20 is fitted into the leg-side recess 21d. In this fitted state, a bolt 75 is inserted from below the leg connecting portion 22 through the bolt insertion hole 22h, and the tip portion of the bolt 75 is tightened into the corresponding bolt fastening hole 32j of the seat support portion 32.

[0051] The example in Figure 12 shows the case where the furniture system 1 has been switched to the second state. In the second state, the support rod 20 is connected to the leg body 21 via the connecting member 107. The connecting member 107 in the second state includes a connecting main body 170 that is disposed between the leg body 21 and the support rod 20. The lower surface of the connecting main body 170 is provided with a connecting side convex portion 171 that protrudes downward and can fit into the leg side concave portion 21d. The upper surface of the connecting main body 170 is provided with a connecting side concave portion 172 that is recessed downward and can fit into the support rod 20.

[0052] A lower wall portion 173 formed in a plate shape along the XY plane is provided on the underside of the connecting main body portion 170. A connecting side protrusion 171 that protrudes downward and can fit into the leg side recess 21d is provided on the center side of the underside of the lower wall portion 173 in the front-to-rear direction. The connecting side protrusion 171 is formed in a convex shape with front and rear edges that follow the front and rear inner surfaces of the leg side recess 21d when viewed from the left-right direction.

[0053] A bolt insertion hole 173h penetrating in the up-down direction is formed on the outer side in the front-rear direction of the lower wall portion 173. The connecting side protrusion 171 is formed in a convex shape having front and rear edges that follow the inner front-rear surfaces of the leg side recess 21d when viewed from the left and right direction. The outer portion of the connecting main body 170 is formed to surround a part of the bolt 77 from the outer side in the front-rear direction and the outer side in the left and right directions.

[0054] The connecting side protrusion 171 is fitted into the leg side recess 21d. The support rod 20 is fitted into the connecting side recess 172. The leg body 21 is fixed to the support rod 20 by being fastened to the seat 30 via the connecting member 107.

[0055] In the second state, the connecting-side protrusion 171 is fitted into the leg-side recess 21d, the upper part of the support rod 20 is fitted into the seat-side recess 30d, and the lower part of the support rod 20 is fitted into the connecting-side recess 172. In this fitted state, a bolt 77 is inserted from below the leg connecting part 22 through the bolt insertion holes 22h and 173h, and the tip side portion of the bolt 77 is tightened into the corresponding bolt fastening hole 32j of the seat support part 32.

[0056] With the leg 21 fastened to the seat 30 via the connecting member 107, the lower surface of the lower wall 173 may abut against the upper surface of the leg connecting portion 22, the lower surface of the connecting-side convex portion 171 may abut against the bottom surface of the leg-side concave portion 21d, the front and rear edges of the connecting-side convex portion 171 may abut against the front and rear inner surfaces of the leg-side concave portion 21d, respectively, the upper surface of the support rod 20 may abut against the upper bottom surface of the seat-side concave portion 30d, or the lower surface of the support rod 20 may abut against the upper surface of the lower wall 173. This allows the leg 21, connecting member 107, and seat 30 to be accurately and stably positioned relative to the support rod 20.

[0057] With the leg 21 fastened to the seat 30 via the connecting member 107, a gap may be formed above the tip of the bolt 77 in the bolt fastening hole 32j. This prevents the bolt 77 from bottoming out when fastened, allowing the support rod 20, the connecting member 107, and the leg 21 to be firmly fixed to the seat 30.

[0058] The support rod 20 is configured so that its vertical position relative to the leg body 21 can be changed by switching between a first state and a second state. By switching between the first state and the second state, it is possible to change the height of the support rod 20 relative to the leg body 21. In the first state, the support rod 20 is lowered to a predetermined level or lower relative to the leg body 21 (see FIG. 10). In the second state, the support rod 20 is higher than a predetermined level relative to the leg body 21 (see FIG. 12).

[0059] For example, the height H of the connecting member 107 may be set in the range of 40 mm to 60 mm. The height of the connecting member 107 corresponds to the height in the vertical direction from the lower surface of the connecting-side protrusion 171 to the upper surface of the lower wall portion 173. The height H of the connecting member 107 is not limited to the above and can be changed according to design specifications.

[0060] Referring to Figures 6, 10 and 13 together, the fixture system 1 is configured to be switchable between a third state (see Figure 6) in which the leg body 21 and the support rod 20 are connected via a connecting member 7 different from that in the second state, and a fourth state (see Figure 13) in which the leg body 21 and the support rod 20 are connected via a connecting member 207 different from that in the third state.

[0061] The example in FIG. 6 shows the furniture system 1 switched to the third state. In the third state, the support rod 20 is connected to the leg 21 via a connecting member 7 that is different from that in the second state. In the third state, the connecting-side protrusion 71 is fitted into the leg-side recess 21d, and a bolt 75 is inserted from below the leg connecting portion 22 through the bolt insertion hole 22h. The tip end of the bolt 75 is fastened into the nut 73j of the connecting member 7. In addition, the upper part of the support rod 20 is fitted into the seat-side recess 30d, and the lower part of the support rod 20 is fitted into the connecting-side recess 72. In this fitted state, a bolt 76 is inserted from below the middle wall portion 74 through the bolt insertion hole 74h, and the tip end of the bolt 76 is fastened into the corresponding bolt fastening hole 32j of the seat support portion 32.

[0062] When viewed from the left-right direction, the support rod 20 is configured to be able to change the inclination of the support rod 20 relative to the leg body 21 by switching between a first state and a third state. In other words, the support rod 20 is configured to be able to change the inclination of the support rod 20 relative to the leg body 21 in the up-down direction by switching between the first state and the third state. By switching between the first state and the third state, it is possible to change the inclination of the support rod 20 relative to the leg body 21 to a forward tilt or a backward tilt. In the third state shown in FIG. 6, the support rod 20 is inclined forward relative to the leg body 21. Although not shown, in another third state, the support rod 20 may be inclined backward relative to the leg body 21.

[0063] For example, the inclination angle A of the upper surface of the middle wall portion 74 of the connecting member 7 may be set in the range of 5 degrees to 45 degrees. The inclination angle A corresponds to the acute angle formed by a line (XY plane) extending along the front-to-rear direction in a side view and a line extending along the upper surface of the middle wall portion 74. The inclination angle A is not limited to the above and can be changed according to design specifications.

[0064] 13 shows the case where the furniture system 1 is switched to the fourth state. In the fourth state, the support rod 20 is connected to the leg 21 via a connecting member 207 that is different from that in the third state. The connecting member 207 that is different from that in the third state includes a connecting body 270 that is disposed between the leg 21 and the support rod 20.

[0065] The connecting body 270 is formed into a shape that follows the XY plane. In a side view, the connecting body 270 extends forward from above the leg connecting portion 22 toward the support rod 20. A connecting side protrusion 271 that protrudes downward and can fit into the leg side recess 21d is provided on the underside of the rear part of the connecting body 270. A connecting side recess 272 that is recessed downward and can fit into the support rod 20 is provided on the upper surface of the front part of the connecting body 270.

[0066] The connecting-side protrusion 271 is fitted into the leg-side recess 21d, the upper part of the support rod 20 is fitted into the seat-side recess 30d, and the lower part of the support rod 20 is fitted into the connecting-side recess 272. In this fitted state, a bolt may be inserted from below the leg connecting part 22 through the bolt insertion hole and the tip part of the bolt may be tightened into the corresponding bolt fastening hole in the rear part of the connecting main body part 270, or a bolt may be inserted from below the front part of the connecting main body part 270 through the bolt insertion hole and the tip part of the bolt may be tightened into the corresponding bolt fastening hole in the seat support part 32 (not shown).

[0067] The support rod 20 is configured to be able to change its position in the front-to-rear direction relative to the leg body 21 by switching between a first state and a fourth state. In the fourth state shown in Fig. 13, the support rod 20 is disposed forward relative to the leg body 21. Although not shown, in another fourth state, the support rod 20 may be disposed rearward relative to the leg body 21.

[0068] <Action and effect> As described above, the furniture system 1 of the above embodiment comprises the leg body 21 placed on the floor surface F, the support rod 20 supported by the leg body 21 and extending in the left-right direction, the seat 30 supported by the support rod 20, and the connecting member 107 provided between the leg body 21 and the support rod 20 so as to be detachable from each of the leg body 21 and the support rod 20 and configured to change the relative positional relationship between the leg body 21 and the support rod 20. The furniture system 1 is configured to be switchable between a first state in which the leg body 21 and the support rod 20 are connected without the connecting member 107, and a second state in which the leg body 21 and the support rod 20 are connected via the connecting member 107. According to this configuration, when switched to the first state, the support rod 20 is connected to the leg 21 without the connecting member 107. On the other hand, when switched to the second state, the support rod 20 is connected to the leg 21 via the connecting member 107. Therefore, it is possible to provide a furniture system 1 that can be changed into various forms.

[0069] In the above embodiment, the fixture system 1 is configured to be switchable between a third state in which the leg body 21 and the support rod 20 are connected via a connecting member 7 different from that in the second state, and a fourth state in which the leg body 21 and the support rod 20 are connected via a connecting member 207 different from that in the third state. According to this configuration, when switched to the third state, the support rod 20 is connected to the leg 21 via a connecting member 7 that is different from that in the second state. On the other hand, when switched to the fourth state, the support rod 20 is connected to the leg 21 via a connecting member 207 that is different from that in the third state. Therefore, it is possible to change to various other forms.

[0070] In the above embodiment, the support rod 20 is configured so that its position in the up-down direction relative to the leg 21 can be changed by switching between the first state and the second state. This configuration makes it possible to change the height of the support rod 20 relative to the leg body 21. When the support rod 20 is made higher than a predetermined height relative to the leg body 21, the seat surface becomes higher, which can assist the seated person in standing up. On the other hand, when the support rod 20 is made lower than a predetermined height relative to the leg body 21, the seat surface becomes lower, which is suitable for people who want to sit comfortably.

[0071] In the above embodiment, the support rod 20 is configured so that the inclination of the support rod 20 relative to the leg 21 can be changed by switching between the first state and the third state when viewed from the left-right direction. This configuration makes it possible to change the inclination of the support rod 20 relative to the leg 21 to be inclined forward or backward. When the support rod 20 is inclined forward relative to the leg 21, the seat surface is inclined forward, which can assist the seated person in standing up. On the other hand, when the support rod 20 is inclined backward relative to the leg 21, the seat surface is inclined backward, which is suitable for people who want to sit deeply when sitting.

[0072] In the above embodiment, the support rod 20 is configured so that its position in the front-rear direction relative to the leg 21 can be changed by switching between the first state and the fourth state. According to this configuration, by changing the front-rear position of the support rod 20 relative to the leg 21, it is possible to change the configuration in a variety of ways.

[0073] In the above embodiment, the connecting members 7 are disposed on both sides of the support rod 20 in the left-right direction. According to this configuration, the support rod 20 can be stably supported at both ends.

[0074] In the above embodiment, the leg 21 is provided with a leg-side recess 21d facing downward, into which the support rod 20 can be fitted. The connecting member 7 includes a connecting main body 70 arranged between the leg 21 and the support rod 20. A connecting-side protrusion 71 that protrudes downward and can be fitted into the leg-side recess 21d is provided on the lower surface of the connecting main body 70. A connecting-side recess 72 facing downward, into which the support rod 20 can be fitted, is provided on the upper surface of the connecting main body 70. According to this configuration, when connection is made without using the connecting member 7, the support rod 20 is fitted into the leg-side recess 21d, thereby enabling the leg 21 to be firmly connected to the support rod 20. On the other hand, when connection is made via the connecting member 7, the connecting-side protrusion 71 is fitted into the leg-side recess 21d and the support rod 20 is fitted into the connecting-side recess 72, thereby enabling the connecting member 7 to be firmly connected to each of the leg 21 and the support rod 20.

[0075] In the above embodiment, the connecting-side protrusion 171 is fitted into the leg-side recess 21d. The support rod 20 is fitted into the connecting-side recess 172. The leg 21 is fixed to the support rod 20 by being fastened to the seat 30 via the connecting member 107. According to this configuration, with the connecting side convex portion 171 engaged with the leg side recess 21d and the support rod 20 engaged with the connecting side recess 172, the leg body 21 is tightened and fixed to the seat 30 via the connecting member 107, thereby firmly fixing the leg body 21, the connecting member 107 and the seat 30 to the support rod 20.

[0076] In the above embodiment, the leg 21 is fastened to the connecting member 7 with the connecting side protrusion 71 fitted into the leg side recess 21d. The connecting member 7 is fastened to the support rod 20 by being fastened to the seat 30 with the support rod 20 fitted into the connecting side recess 72. According to this configuration, the leg body 21 is tightened and fixed to the connecting member 7 with the connecting side convex portion 71 fitted into the leg side concave portion 21d, and the connecting member 7 is tightened and fixed to the seat 30 with the support rod 20 fitted into the connecting side concave portion 72, thereby firmly fixing the leg body 21, connecting member 7 and seat 30 to the support rod 20.

[0077] In the above embodiment, a plurality of seats 30 are provided side by side in the left-right direction. According to this configuration, the relative positional relationship between the multiple seats 30 and the leg bodies 21 can be changed by attaching and detaching the connecting members 7. Therefore, by adding a small number of members, the positional relationship of all the seats 30 relative to the leg bodies 21 can be changed all at once.

[0078] In the above embodiment, the optional members 4 are further provided, which are arranged side by side in the left-right direction of the seat 30 in a plan view and supported by the support rod 20. According to this configuration, the relative positional relationship between the optional member 4 and the leg 21 can be changed together with the seat 30 by attaching and detaching the connecting member 7. Therefore, by adding a small number of members, the positional relationship between the seat 30 and the optional member 4 relative to the leg 21 can be changed all at once.

[0079] Furthermore, according to the embodiment, the seat height can be adjusted to an optimum position. For example, the seat height can be changed from a standard seat height (e.g., about 420 mm) that is easy to stand up and sit down at to a seat height (e.g., about 480 mm) that is easy to stand up and sit down at for people who require support for their legs and hips, or to a seat height (e.g., about 530 mm) that is easy for patients on crutches to sit down at.

[0080] Furthermore, according to the embodiment, a configuration can be provided in which a seat and armrests are combined to make it easy to stand up and sit down. For example, when the seat is normally tilted backward, the seat can be set to a first state in which the legs and support rods are connected without a connecting member, allowing the occupant to sit comfortably. On the other hand, if priority is given to ease of standing up and sitting down, the seat can be set to a third state in which the legs and support rods are connected via a connecting member different from that in the second state, and the tilt of the support rods relative to the legs can be changed to a forward tilt, thereby raising the seat so that it is flat. In addition, tilting the armrests at the same time makes them more comfortable for the occupant's arms, making it easier for the occupant to place their hands on the seat when standing up.

[0081] Furthermore, according to the embodiment, armrests are provided on both the left and right sides of the middle seat in the left-right direction, so that the armrests can be used as an aid when standing up and sitting down. Furthermore, armrests are not provided on the outside of the two outer seats in the left-right direction, so it is possible to park a wheelchair or stroller next to the seat or to communicate with other passengers. This allows for flexibility when priority seats are set up.

[0082] Furthermore, according to the embodiment, by providing one connecting member per leg, it is possible to raise the height (change the relative positional relationship between the leg and the support rod) with a minimum number of parts, which makes it possible to reduce the number of construction steps.

[0083] Furthermore, according to the embodiment, the same configuration as the current (existing) model can be achieved in terms of ease of cleaning, prevention of the placement of hazardous materials, etc. For example, by setting the legs and the support rod in the first state in which they are connected without a connecting member, the height of the support rod and the seat can be set to the same as the current model. Therefore, by widening the leg area, it is possible to improve the ease of cleaning and prevent hazardous materials from being placed under the seat.

[0084] <Modification> In the above embodiment, an example has been described in which the fixture system is switchable between a third state in which the legs and the support rod are connected via a connecting member different from that in the second state, and a fourth state in which the legs and the support rod are connected via a connecting member different from that in the third state, but this is not limited to this. For example, the fixture system may be configured to be switchable from the first state or the second state to the third state, but not switchable to the fourth state. For example, the fixture system may be configured to be switchable from the first state or the second state to the third state or the fourth state. The fixture system may be configured to be switchable at least between the first state and the second state. The manner of switching to a state different from the second state can be changed according to design specifications.

[0085] In the above embodiment, an example has been described in which the support rod is configured to be able to change its position in the up-down direction relative to the leg body by switching between a first state and a second state, but this is not limited to this. For example, the support rod may be configured to be able to change its inclination relative to the leg body by switching between the first state and the second state, or to change its position in the front-to-back direction relative to the leg body, or to change its position in the left-to-right direction relative to the leg body, or to change to a combination of these. The furniture system may be configured so that the relative positional relationship between the leg body and the support rod can be changed. The configuration for changing the relative positional relationship between the leg body and the support rod can be changed according to design specifications.

[0086] In the above embodiment, an example has been described in which the support rod is configured to be able to change the inclination of the support rod relative to the leg body by switching between a first state and a third state when viewed from the left and right, but this is not limited to this. For example, the support rod may be configured to be able to change its position in the front-to-back direction relative to the leg body by switching between the first state and the third state, or it may be configured to be able to change its position in the left-to-right direction relative to the leg body, or it may be configured to be able to change to a combination of these. The furniture system may be configured so that the relative positional relationship between the leg body and the support rod can be changed. The configuration for changing the relative positional relationship between the leg body and the support rod can be changed according to design specifications.

[0087] In the above embodiment, an example has been described in which the support rod is configured to be able to change its position in the front-to-rear direction relative to the leg body by switching between the first state and the fourth state, but this is not limited to this. For example, the support rod may be configured to be able to change its position in the left-to-right direction relative to the leg body by switching between the first state and the fourth state, or it may be configured to be able to change to a position that is a combination of these. The furniture system may be configured so that the relative positional relationship between the leg body and the support rod can be changed. The configuration for changing the relative positional relationship between the leg body and the support rod can be changed according to the design specifications.

[0088] In the above embodiment, the connecting members are disposed on both sides of the support rod in the left-right direction, but this is not limiting. For example, the connecting members may be disposed on the center side of the support rod in the left-right direction. For example, the connecting members may be disposed in positions corresponding to the installation locations of the legs. The arrangement of the connecting members in the left-right direction of the support rod can be changed according to design specifications.

[0089] In the above embodiment, an example has been described in which the leg has a leg-side recess that is recessed downward and into which the support rod can fit, but this is not limited to this. For example, the leg may have a leg-side abutment that can abut against the support rod. For example, the leg may not have a leg-side recess. For example, when connecting without a connecting member, the leg may be fastened and fixed to the support rod with the leg-side abutment abutting against the support rod. The manner in which the leg is connected to the support rod can be changed according to design specifications.

[0090] In the above embodiment, the connecting member includes a connecting body disposed between the leg and the support rod, and the lower surface of the connecting body is provided with a connecting-side protrusion that protrudes downward and can fit into the leg-side recess. However, this is not limited to this. For example, the lower surface of the connecting body does not need to be provided with a connecting-side protrusion. For example, when connecting via a connecting member, the connecting member may be fastened to the leg with the lower surface of the connecting body abutting against the leg. The manner in which the connecting member is connected to the leg can be changed according to design specifications.

[0091] In the above embodiment, an example was described in which the upper surface of the connecting body is provided with a connecting-side recess that is recessed downward and into which the support rod can fit, but this is not limited to this. For example, the upper surface of the connecting body does not have to be provided with a connecting-side recess.
