Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the above-described conventional furniture unit, since the plug-connecting furniture and the bench are connected by a connecting frame that extends horizontally forward from the support column of the plug-connecting furniture, there is a concern that the overall appearance quality of the furniture unit is impaired by the connecting frame having a large cross section. ​Another possible solution is to reduce the cross-section of the connecting frame. While this would avoid a decrease in appearance quality, it would reduce the support stability of the plug-connected fixtures.

[0006] Therefore, the present invention can enhance support stability while suppressing a decrease in appearance quality. Fixture units and plug-in fixtures This aims to provide... [Means for solving the problem]

[0007] The plug-connecting fixture according to the present invention is a plug-connecting fixture that is elongated in the vertical direction and has a plug-connecting portion, and is supported by a support structure via a connecting member, and is characterized by comprising a groove formed along the vertical direction on the outer surface, and a connected portion disposed within the groove and to which the connecting member is connected.

[0008] With the above configuration, the connecting portion of the connecting member is housed within the groove and connected to the connected portion of the plug-connecting fixture. As a result, the connecting portion of the connecting member on the plug-connecting fixture side is hidden within the groove and is difficult to see from the outside. Furthermore, the connected portion of the plug-connecting fixture is located within a groove that extends vertically. Therefore, by connecting the connecting portion of the connecting member to a wide area in the vertical direction within the groove, or to a position sufficiently spaced apart vertically, a vertically long plug-connecting fixture can be stably supported by the support structure.

[0009] The plug-connecting fixture further comprises a skeletal member extending in the vertical direction and a cover member that covers the outside of the skeletal member and is detachably attached to the skeletal member, wherein at least a portion of the skeletal member is exposed inside the groove, and the connected portion may be positioned on the exposed portion of the skeletal member within the groove.

[0010] In this case, the cover member can be removed from the frame member without removing the connecting member from the plug-connecting fixture. Therefore, during maintenance, only the cover member can be removed to perform the maintenance work. Thus, adopting this configuration improves workability during maintenance.

[0011] The plug connector fixture comprises two grooves on which the connected portion is located, and the two grooves on which the connected portion is located may be formed symmetrically with their openings facing opposite sides in the horizontal cross-section of the plug connector fixture.

[0012] In this case, two different connecting members can be connected to each of the two grooved sections. Therefore, when this configuration is adopted, the symmetrical positions in the horizontal cross-section of the plug-connecting fixture can be stably supported by the two connecting members.

[0013] The connected portions may be arranged at multiple locations within the groove that are spaced apart in the vertical direction, and the connecting member may be selectively connected to any of the connected portions.

[0014] In this case, the part of the plug-connected fixture that is to be connected can be selected and used to match the height of the connection part with the connecting member on the support structure side. Therefore, when this configuration is adopted, it can be easily applied to support structures with various specifications that have different heights of connection parts with the connecting member.

[0015] The fixture unit according to the present invention comprises a fixture body installed on the floor, a plug-connecting fixture having a plug-connecting portion and being elongated in the vertical direction, and a connecting member connecting the plug-connecting fixture to the fixture body, wherein the plug-connecting fixture has a groove formed along the vertical direction on its outer surface, and the connecting member has a first connecting portion that is coupled to the plug-connecting fixture, a second connecting portion that is coupled to the fixture body, and an arm portion that connects the first connecting portion and the second connecting portion, wherein the first connecting portion is coupled to the plug-connecting fixture within the groove.

[0016] With the above configuration, the connecting member is connected to the plug-connecting fixture with its first connecting portion housed within the groove. As a result, the first connecting portion of the connecting member is hidden within the groove and difficult to see from the outside. Furthermore, the first connecting portion of the connecting member is connected to the plug-connecting fixture within a groove that extends vertically. Therefore, the first connecting portion of the connecting member can be connected to the plug-connecting fixture over a wide range in the vertical direction, or at a position sufficiently spaced apart vertically. Consequently, even a vertically long plug-connecting fixture can be stably supported by the fixture body using the connecting member.

[0017] The plug connection fixture has multiple plug connection parts arranged such that the plugs are attached and detached in different directions when viewed from above, and also has two grooves into which different connecting members are connected, and the two connecting members connected to each groove may be arranged in a V-shape when viewed from above, such that the distance between them gradually widens from the plug connection fixture towards the fixture body.

[0018] In this case, the two connecting members, which are positioned to open outwards in a V-shape from the plug connector towards the fixture body, can stably support the load of plug attachment and detachment on the fixture body. Therefore, even if the connecting members are made smaller to improve the appearance quality, the wobbling of the plug connector due to plug attachment and detachment can be suppressed.

[0019] The vertical width of the first connecting portion may be set to be wider than the vertical width of the arm portion.

[0020] In this case, the vertical width of the first joint can be increased to enhance support stability to the plug-connecting fixture, while the vertical width of the arm portion exposed to the outside of the plug-connecting fixture can be narrowed to improve the appearance quality. [Effects of the Invention]

[0021] In the plug-connecting fixture according to the present invention, since a coupling portion for coupling a connecting member is arranged in a groove portion extending in the vertical direction, by coupling the connecting member to the coupling portion in the groove portion, while suppressing an increase in size of the connecting member and external exposure of a coupling portion between the connecting member and the plug-connecting fixture, the connecting member can stably support the support structure. Therefore, when the plug-connecting fixture according to the present invention is adopted, it is possible to enhance the support stability while suppressing a deterioration in appearance quality.

[0022] Further, in the fixture unit according to the present invention, since a groove portion extending in the vertical direction is formed on an outer surface of the plug-connecting fixture and a first coupling portion of the connecting member is coupled to the plug-connecting fixture within the groove portion, while suppressing an increase in size of the connecting member and external exposure of a coupling portion between the connecting member and the plug-connecting fixture, the plug-connecting fixture can stably support the fixture body. Therefore, when the fixture unit according to the present invention is adopted, it is possible to enhance the support stability of the plug-connecting fixture while suppressing a deterioration in appearance quality.

Mode for Carrying Out the Invention

[0024] Embodiments of the present invention will be described below with reference to the drawings. Figure 1 is a perspective view of the furniture unit 1 of this embodiment. Figure 2 is a side view of the furniture unit 1, and Figure 3 is a partial cross-sectional plan view of the furniture unit 1 with the individual chair 51 (described later) removed. In this embodiment, the furniture unit 1 consists of a bench 2, which is the furniture body, and a plug-connection furniture unit 3, which are integrally connected by a connecting member 4. The bench 2 is installed on the floor surface F and constitutes a support structure that supports the plug-connection furniture unit 3. Hereinafter, the side facing forward when a person is seated on the bench 2 in a normal posture will be referred to as the front side, the opposite side as the rear side, and the directions to the left and right of a person seated on the bench 2 in a normal posture will be referred to as the left and right directions.

[0025] The bench 2 has a rectangular cross-section support rod 50 (beam member) that extends approximately horizontally in the left-right direction, and multiple individual chairs 51 are supported and fixed to it. Legs 52 are attached to both ends in the longitudinal direction of the support rod 50, and the support rod 50 is installed on the floor surface F via these legs 52. The support rod 50 is made of a highly rigid metal material because it supports the weight of multiple individual chairs 51 and the occupants. All individual chairs 51 attached to the support rod 50 have the same structure. In addition, an armrest 53 is provided on the side of each individual chair 51, which is supported and fixed to the support rod 50.

[0026] The individual chair 51 comprises a seat 54 that supports the seated person's buttocks, a backrest 55 that supports the seated person's back, and a pair of connecting legs 56 that extend downward from the lower surface of the left and right side edges of the seat 54, with their lower end regions fixed to a support rod 50. A fitting recess (not shown) that opens downward in a roughly U-shape is formed at the lower end of each connecting leg 56, and this fitting recess is fitted into the upper half of the support rod 50.

[0027] The leg body 52 comprises a base portion 52a whose upper end is attached to the support rod 50, and a front leg 52b and a rear leg 52c that branch and extend from the base portion 52a. Floor contact members 58 are attached to the lower ends of the front leg 52b and the rear leg 52c. A fitting recess 52a-1 that opens upward is formed on the upper surface of the base portion 52a of the leg body 52, and this fitting recess 52a-1 is fitted into the lower half of the support rod 50. In this state, the base portion 52a of the leg body 52 is fixed to the support rod 50 by being bolted to the connecting leg 56 at the outer end of the single chair 51 at the end. Furthermore, the connecting legs 56 at the inner end of the end-type individual chair 51 and the connecting legs 56 of the remaining individual chair 51 sandwich the support rod 50 between them and a roughly U-shaped receiving bracket 57 that opens upward, and are fixed to the support rod 50 by being bolted to the receiving bracket 57 in that state.

[0028] The plug connection unit 3 is a unit equipped with connector blocks 10 that allow plugs such as power plugs and communication plugs (e.g., USB plugs, wired LAN connection plugs) to be plugged in and out, and is formed to be long in the vertical direction. The plug connection unit 3 of this embodiment is equipped with four similar connector blocks 10. Each connector block 10 has a power plug socket 11 on the end face that is exposed to the outside, to which a power plug can be plugged in and out, and a communication plug socket 12 to which a communication plug can be plugged in and out. In this embodiment, the power plug socket 11 and the communication plug socket 12 constitute the plug connection section.

[0029] The plug-connection fixture 3 comprises a skeletal member 13 extending in the vertical direction, a front cover member 14F covering the front side of the skeletal member 13, and a rear cover member 14R covering the rear side of the skeletal member 13. Cables (power cables and signal cables), not shown, connected to each of the connector blocks 10 sockets 11 and 12 are supported by the skeletal member 13. Cables pulled out from the bottom of the skeletal member 13 are connected to the power and signal wiring of the facility where the fixture unit 1 is installed. The front cover member 14F and the rear cover member 14R are detachably attached to the skeletal member 13 by screws or the like.

[0030] Figure 4 is a perspective view of the skeletal member 13 from the rear. Figure 5 is a diagram showing the front view (a), side view (b), and top view (c) of the rear cover member 14R. The front cover member 14F has the same structure as the rear cover member 14R. Figure 6 is a cross-sectional view along the line VI-VI in Figure 2. As shown in Figure 4, the skeletal member 13 comprises a base plate 13a installed on the floor surface F, a pair of side frames 13b extending vertically upward from the base plate 13a, and a plurality of connecting frames 13c extending horizontally and connecting the pair of side frames 13b to each other. The pair of side frames 13b are arranged on the base plate 13a spaced apart in the left-right direction.

[0031] The base plate 13a is made of a rectangular metal plate that is longer in the front-to-back direction than in the left-to-right direction. The left and right side frames 13b have a cross-sectional shape (see Figure 6) in which a long metal plate in the vertical direction is bent multiple times in a direction intersecting the vertical direction. Display panels 15 made of acrylic resin or the like are attached to the upper ends of the left and right side frames 13b. The display panels 15 show diagrams of plugs, etc., so that it can be recognized from the outside that there is a fixture that can be connected to a plug. The connecting frame 13c is made of a metal plate.

[0032] Near the upper ends of the rear surfaces of the left and right side frames 13b, metal fixing pieces 16 are installed for screwing the rear cover member 14R in place. Furthermore, a retaining plate 17 for holding two connector blocks 10 is fixed to the upper rear region of the left and right side frames 13b, below the installation position of the fixing pieces 16. The retaining plate 17 has a shape in which its central portion in the left-right direction protrudes to the rear in a roughly V-shape. The left and right side edges of the retaining plate 17 are connected to the rear surfaces of the left and right side frames 13b. On the left and right inclined walls flanking the central top of the retaining plate 17, fitting and fixing openings 18 are formed for fitting and fixing the corresponding connector blocks 10. The left and right fitting and fixing openings 18 are formed at different heights in the vertical direction. Each connector block 10 is fixed to the fitting and fixing opening 18 such that its insertion openings 11 and 12 face in a direction approximately perpendicular to the inclined walls of the retaining plate 17. As a result, the sockets 11 and 12 of the left connector block 10 on the rear side face diagonally to the rear left, and the sockets 11 and 12 of the right connector block 10 on the rear side face diagonally to the rear right.

[0033] In Figure 4, the skeletal member 13 is viewed from the rear, so the structure on the front side is not visible, but the front side of the skeletal member 13 has the same structure as the rear side. Fixing pieces 16 and retaining plates 17, which have the same structure as the rear side, are attached to the front side of the left and right side frames 13b at the same height as those on the rear side. Corresponding connector blocks 10 are fitted and fixed into the left and right fitting and fixing openings 18 of the front side retaining plate 17. As a result, the insertion openings 11 and 12 of the left connector block 10 on the front side face diagonally forward to the left, and the insertion openings 11 and 12 of the right connector block 10 on the front side face diagonally forward to the right. Note that the arrows in Figure 3 indicate the direction in which the plugs are attached to and detached from the front and rear connector blocks 10.

[0034] Furthermore, as shown in Figure 6, the left and right side frames 13b have a roughly hat-shaped cross-section in the horizontal direction. More specifically, the left and right side frames 13b have an outer wall 13b-1 facing outward in the left-right direction, a rear wall 13b-2 and a front wall 13b-3 that bend inward in the left-right direction from the rear and front ends of the outer wall 13b-1, a rear flange 13b-4 that bends rearward from the inner end of the rear wall 13b-2, and a front flange 13b-5 that bends forward from the inner end of the front wall 13b-3. The left and right side edges of the rear retaining plate 17 are fastened and fixed to the rear wall 13b-2 of the left and right side frames 13b by screws 19. Similarly, the left and right side edges of the front retaining plate 17 are fastened and fixed to the front wall 13b-3 of the left and right side frames 13b by screws 19.

[0035] As shown in Figure 5, the rear cover member 14R is made of a vertically elongated metal plate that is bent so that its center in the left-right direction protrudes to the rear in a roughly V-shape. The front cover member 14F has the same structure as the rear cover. Therefore, only the detailed structure of the rear cover member 14R will be described below, and the detailed structure of the front cover member 14F will not be described.

[0036] As shown in Figures 5 and 6, the rear cover member 14R has inclined walls 14b on both the left and right sides of the top portion 14a that protrudes to the rear. On the left and right inclined walls 14b, at positions corresponding to the left and right fitting and fixing holes 18 of the rear retaining plate 17, a substantially rectangular opening 20 is formed to expose a portion of the end face of the connector block 10 held in each fitting and fixing hole 18 to the outside. The insertion holes 11 and 12 on the end faces of each connector block 10 are exposed to the outside of the rear cover member 14R through the opening 20.

[0037] Reinforcement plates 21 are attached to multiple vertically spaced locations on the inside of the rear cover member 14R. Each reinforcement plate 21 is attached to the left and right inclined walls 14b on the inside of the rear cover member 14R by welding or the like. A tongue-shaped piece 22 protruding to the rear is extended from the upper end of the reinforcement plate 21 located near the upper end of the rear cover member 14R. The tongue-shaped piece 22 is superimposed on the upper surface of the fixing piece 16 of the skeletal member 13 shown in Figure 4 and fastened to the fixing piece 16 by screws (not shown). The upper end of the rear cover member 14R is open, and this opening is detachably closed by a separate lid member 23 shown in Figure 1. The screw fastening of the tongue-shaped piece 22 to the fixing piece 16 is performed by passing it through the opening at the upper end before attaching the lid member 23 to the upper end of the rear cover member 14R.

[0038] As shown in Figure 6, the left and right inclined walls 14b of the rear cover member 14R are provided with bent walls 24 that are sharply bent inward in the left and right directions at their lateral extension ends. When the rear cover member 14R is assembled to the frame member 13, the tip of the bent wall 24 abuts against or is close to the surface of the outer wall 13b-1 of the side frame 13b of the frame member 13. Similarly, as shown in Figure 6, when the front cover member 14F is assembled to the frame member 13, the tip of the bent wall 24 of the front cover member 14F abuts against or is close to the surface of the outer wall 13b-1.

[0039] At this time, the outer wall 13b-1 of the skeletal member 13 and the bent walls 24 of the rear cover member 14R and the front cover member 14F form a groove 25 with a roughly U-shaped cross-section that opens outward in the left-right direction. The groove 25 is formed on the outer surface of the plug connection fixture 3 so as to extend along the vertical direction. Furthermore, as shown in Figure 3, the two grooves 25 on the left and right sides are formed symmetrically with respect to the center line o1 connecting the tops 14a of the front cover member 14F and the rear cover member 14R, with their openings facing opposite sides in the rhomboid horizontal cross-section of the plug connection fixture 3. As shown in Figure 2, the outer wall 13b-1 forming the bottom surface of each groove 25 has a pair of screw holes 27, which are the connecting parts to which the connecting member 4 is attached, formed at multiple locations spaced apart in the vertical direction. Therefore, a portion of the skeletal member 13 is exposed inside each groove 25, and the screw hole 27, which is the part to be connected, is located in the exposed portion.

[0040] Furthermore, locking claws 26 that protrude toward the front are provided at one location near the upper end and two locations near the lower end of the extended ends of the left and right inclined walls 14b of the rear cover member 14R. Each of these locking claws 26 is inserted into a slit (not shown) formed in the side frame 13b (rear wall 13b-2) of the skeletal member 13, and in that state is screwed to the side frame 13b.

[0041] Furthermore, the base plate 13a at the lower end of the skeletal member 13 shown in Figure 4 is covered by a base cover 37, which is a decorative panel, as shown in Figures 1 to 3.

[0042] Figure 7 is an enlarged view of part VII in Figure 1, showing the connection portion of the connecting member 4 on the plug-connecting fixture 3 side. Figure 8 is a perspective view of the connecting member 4, and Figures 8(a) and (b) sequentially show the procedure for connecting the connecting member 4 to the support rod 50 of the bench 2. Figure 9 is a perspective view of the connecting member 4, and Figures 9(a) and (b) sequentially show the assembly procedure for the connecting member 4. In this embodiment, two symmetrical connecting members 4 are used. Each connecting member 4 has a first connecting portion 28 that is connected to the plug-connecting fixture 3, a second connecting portion 29 that is connected to the support rod 50 of the bench 2, and an arm portion 30 that connects the first connecting portion 28 and the second connecting portion 29.

[0043] The first connecting portion 28 is composed of a rectangular metal block that is elongated in the vertical direction. The first connecting portion 28 is positioned within the groove 25 of the plug connector 3. The thickness of the first connecting portion 28 in the left-right direction is set to be approximately the same as the depth of the groove 25. Screw holes 31 are formed near the upper and lower ends of the first connecting portion 28. These screw holes 31 are aligned with one of the pairs of screw holes 27 in the groove 25, and fixing screws 32 are inserted as shown in Figure 7. The first connecting portion 28 is thus connected within the groove 25 of the plug connector 3 by tightening the fixing screws 32 into the screw holes 27.

[0044] As shown in Figure 8, the second connecting portion 29 consists of an upper clamp 29a fitted to the upper half of the support rod 50 of the bench 2, and a lower clamp 29b fitted to the lower half of the support rod 50 of the bench 2. The upper clamp 29a and the lower clamp 29b are formed from metal plates. The upper clamp 29a has an upper wall 29a-1 that abuts the upper surface of the support rod 50, a rear wall 29a-2 that abuts the rear surface of the support rod 50, and a front wall 29a-3 that abuts the front surface of the support rod 50, with the vertical extension length of the rear wall 29a-2 being longer than the vertical extension length of the front wall 29a-3. Joining flanges 29a-4 that bend outward are provided at the lower ends of the rear wall 29a-2 and the front wall 29a-3, respectively.

[0045] The lower clamp 29b comprises a lower wall 29b-1 that abuts the lower surface of the support rod 50, a rear wall 29b-2 that abuts the rear surface of the support rod 50, and a front wall 29b-3 that abuts the front surface of the support rod 50, with the vertical extension length of the front wall 29b-3 being longer than the vertical extension length of the rear wall 29b-2. Joining flanges 29b-4 that bend outward are extended from the lower ends of the rear wall 29b-2 and the front wall 29b-3, respectively. The second connecting part 29 is fixed to the support rod 50 of the bench 2 by fitting the upper clamp 29a and lower clamp 29b onto the support rod 50 of the bench 2 from above and below, respectively, and then fastening the connecting flanges 29a-4 and 29b-4 together with screws 33.

[0046] The arm portion 30 is formed from a metal rectangular tube member with a vertically elongated cross-section. The first connecting portion 28 is integrally attached to the rear end of the arm portion 30 by welding or the like, and the upper clamp 29a of the second connecting portion 29 is detachably attached to the front end of the arm portion 30 by screw fastening (see screw 34 in Figure 9) or the like. The arm portion 30 has a vertically elongated cross-sectional shape in which the vertical width is wider than the horizontal width, but the vertical width of the arm portion 30 is narrower than the vertical width of the first connecting portion 28. Conversely, the vertical width of the first connecting portion 28 is set to be wider than the vertical width of the arm portion 30. Furthermore, since the upper clamp 29a of the second connecting portion 29 is detachably connected to the front end of the arm portion 30, it can be replaced with a different upper clamp 29a and lower clamp 29b of different sizes and shapes depending on the size and shape of the support rod 50 to be attached.

[0047] In this embodiment, as shown in Figure 3, two different connecting members 4 are connected within the left and right grooves 25 of the plug-connecting fixture 3. The connecting members 4 connected within each groove 25 are arranged in a V-shape when viewed from above, with the distance between them gradually increasing from the plug-connecting fixture 3 towards the bench 2 (fixture body), and their front ends are connected to the support rods 50 of the bench 2.

[0048] As described above, the plug-connecting fixture 3 of this embodiment has a groove 25 extending vertically along its outer surface, and a screw hole 27 (connected portion) into which the first connecting portion 28 of the connecting member 4 is connected is located within the groove 25. Therefore, by connecting the connecting member 4 to the screw hole 27 portion (connected portion) within the groove 25, it is possible to stably support the plug-connecting fixture 3 on the bench 2 with the connecting member 4 while suppressing the enlargement of the connecting member 4 and the external exposure of the connection portion between the connecting member 4 and the plug-connecting fixture 3. Thus, when the plug-connecting fixture 3 of this embodiment is adopted, it is possible to improve support stability while suppressing a decrease in appearance quality.

[0049] Furthermore, the plug-connecting fixture 3 of this embodiment is equipped with two grooves 25 to which different connecting members 4 are joined, and the two grooves 25 are formed such that their openings face opposite sides in the horizontal cross-section of the plug-connecting fixture 3 and are symmetrical with respect to the center line o1. Therefore, when the plug-connecting fixture 3 of this embodiment is adopted, the symmetrical positions in the horizontal cross-section of the plug-connecting fixture 3 can be stably supported by the two connecting members 4.

[0050] Furthermore, the plug-connecting fixture 3 of this embodiment comprises a skeletal member 13 extending in the vertical direction, and a front cover member 14F and a rear cover member 14R that are detachably attached to the skeletal member 13, with the groove 25 being formed by the skeletal member 13, the front cover member 14F, and the rear cover member 14R. The screw holes 27, which are the connecting parts within the groove 25, are formed in the skeletal member 13. Therefore, maintenance of the inside of the plug-connecting fixture 3 can be performed by removing at least one of the front cover member 14F and the rear cover member 14R without removing the connecting member 4 from the plug-connecting fixture 3. Thus, when the plug-connecting fixture 3 of this embodiment is adopted, the workability during maintenance can be improved.

[0051] Furthermore, in this embodiment, the plug-connecting fixture 3 has multiple pairs of screw holes 27, which are the parts to be connected, formed at vertically spaced locations within the groove 25, and the first connecting portion 28 of the connecting member 4 can be selectively connected to any pair of screw holes 27. Therefore, the height of the connection between the connecting member 4 and the plug-connecting fixture 3 can be changed to match the height of the connection between the connecting member 4 and the bench 2 (support structure, fixture body). Consequently, when the plug-connecting fixture 3 of this embodiment is adopted, it can be easily applied to benches 2 (support structure, fixture body) with various specifications that have different connection heights with the connecting member 4.

[0052] Furthermore, in this embodiment, the fixture unit 1 has two connecting members 4 that are connected to different grooves 25, and in a top view, they are arranged in a V-shape such that the distance between them gradually widens from the plug-connecting fixture 3 towards the bench 2 (fixture body). Therefore, when plugs are attached to or detached from the plug connection parts (insertion ports 11, 12) of the plug-connecting fixture 3, the load of attaching and detaching the plugs can be stably supported by the bench 2. Consequently, when the fixture unit 1 of this embodiment is adopted, even if each connecting member 4 is made smaller to improve the appearance quality, the wobbling of the plug-connecting fixture 3 due to the attachment and detachment of plugs can be suppressed.

[0053] Furthermore, in this embodiment, the vertical width of the first connecting portion 28 of the connecting member 4 of the fixture unit 1 is set to be wider than the vertical width of the arm portion 30 of the connecting member 4. Therefore, by widening the vertical width of the first connecting portion 28, the support stability for the plug-connecting fixture 3 can be increased, while the vertical width of the arm portion 30 exposed to the outside of the plug-connecting fixture 3 can be narrowed to further improve the appearance quality.

[0054] Furthermore, in this embodiment, the fixture unit 1 has a second connecting portion 29 of the connecting member 4 that is detachably connected to the arm portion 30 of the connecting member 4. Therefore, when this embodiment of the fixture unit 1 is adopted, it is possible to easily accommodate various benches 2 (fixture body) with different specifications by replacing the second connecting portion 29 of the connecting member 4 with one of a different size or shape.

[0055] It should be noted that the present invention is not limited to the embodiments described above, and various design modifications are possible without departing from the spirit of the invention. For example, in the above embodiment, the furniture unit 1 is configured by connecting a plug-connected furniture unit 3 to a bench 2 which is the furniture body, but the furniture body that constitutes the furniture unit is not limited to a bench, but may be other furniture such as a desk or a cart. Furthermore, in the plug-connected furniture unit 3 of the above embodiment, a front cover member 14F and a rear cover 14B are detachably attached to the front and rear sides of the frame member 13, respectively, but the cover members may be attached to only one of the front or rear sides of the frame member 13. Furthermore, the support structure that supports the plug-connected furniture via the connecting member is not limited to furniture such as benches, but may also be the wall of a building, etc. [Explanation of Symbols]
