Description

Technical Field

[0001] The present invention relates to a plug connection fixture to which a plug for supplying power, communicating electronic data, etc. is connected, and a fixture unit.

Background Art

[0002] In recent years, due to the spread of portable communication terminals such as smartphones and notebook computers, there has been a demand for facilities that can connect plugs for power supply and plugs for electronic data communication in various places such as airports, stations, and offices. In response to such demands, a fixture unit in which a plug connection fixture is integrated with a fixture body such as a bench has been developed (see, for example, Patent Document 1).

[0003] In the fixture unit described in Patent Document 1, a plug connection fixture having a plurality of plug connection portions is disposed on the back of a bench that is the fixture body. The plug connection fixture has a support column extending upward from the floor surface, and is coupled to a beam member of the bench by a connecting frame that extends horizontally forward from the support column. In this fixture unit, since a plurality of plug connection portions are disposed in the vicinity of the back of the bench on which a person sits, the convenience when a person sitting on the bench uses a device such as a communication terminal is improved.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the above conventional fixture unit, since the plug connection fixture and the bench are connected by a connecting frame that extends horizontally forward from the support column of the plug connection fixture, there is a concern that the overall appearance quality of the fixture unit may be impaired by the connecting frame having a large cross section. As a countermeasure, it may be considered to reduce the cross-section of the connecting frame. In this case, although a decrease in appearance quality can be avoided, the support stability of the plug connection fixture will decrease accordingly.

[0006] Therefore, the present invention aims to provide a plug connection fixture and a fixture unit that can enhance the support stability while suppressing a decrease in appearance quality.

Means for Solving the Problem

[0007] The plug connection fixture according to the present invention is a plug connection fixture that is long in the vertical direction and has a plug connection portion, and is supported by a support structure via a connecting member, and includes a groove portion formed along the vertical direction on an outer surface, and a coupled portion disposed in the groove portion to which the connecting member is coupled.

[0008] With the above configuration, the coupling portion of the connecting member is coupled to the coupled portion of the plug connection fixture while being accommodated in the groove portion. For this reason, the coupling portion of the connecting member on the plug connection fixture side is hidden in the groove portion and is less visible from the outside. Further, the coupled portion of the plug connection fixture is disposed in the groove portion extending along the vertical direction. Therefore, by coupling the coupling portion of the connecting member within a wide range in the vertical direction in the groove portion or at positions sufficiently separated vertically, a plug connection fixture that is long in the vertical direction can be stably supported by the support structure.

[0009] The plug connection fixture may further include 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, and at least a part of the skeletal member is exposed inside the groove portion, and the coupled portion may be disposed at the exposed portion of the skeletal member in the groove portion.

[0010] In this case, the cover member can be removed from the skeletal 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. Accordingly, when this configuration is adopted, the workability during maintenance can be improved.

[0011] The plug connecting fixture includes two groove portions in which the to-be-connected portion is disposed, and the two groove portions in which the to-be-connected portion is disposed may be formed so that their openings face opposite sides and are line-symmetric in the horizontal cross-section of the plug connecting fixture.

[0012] In this case, two different connecting members can be coupled to the to-be-connected portions of the two groove portions. Therefore, when this configuration is adopted, the line-symmetric positions in the horizontal cross-section of the plug connecting fixture can be stably supported by the two connecting members.

[0013] The to-be-connected portion is disposed at a plurality of locations spaced apart in the vertical direction within the groove portion, and the connecting member may be selectively coupled to the to-be-connected portion at any one location.

[0014] In this case, the to-be-connected portion on the plug connecting fixture side can be selected and used in accordance with the height of the coupling portion with the connecting member on the support structure side. Therefore, when this configuration is adopted, it can be easily applied to support structures of various specifications having different heights of the coupling portion with the connecting member.

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

[0016] With the above configuration, the connecting member is coupled to the plug connecting device with the first coupling portion housed in the groove portion. For this reason, the first coupling portion of the connecting member is hidden in the groove portion from the outside and becomes less visible from the outside. Further, the first coupling portion of the connecting member is coupled to the plug connecting device within the groove portion extending along the vertical direction. For this reason, the first coupling portion of the connecting member can be coupled to a wide range in the vertical direction of the plug connecting device or at positions sufficiently separated vertically. Therefore, thereby, a vertically long plug connecting device can be stably supported by the connecting member on the device body.

[0017] A plurality of the plug connecting portions may be arranged such that the plug detachment directions are different in a top view, and the plug connecting device may include two groove portions to which different connecting members are respectively coupled, and two connecting members coupled to each groove portion may be arranged in a V shape such that the separation width between them gradually increases from the plug connecting device toward the device body in a top view.

[0018] In this case, the plug detachment load can be stably supported on the device body by the two connecting members arranged to open in a V shape from the plug connecting device toward the device body. For this reason, even if each connecting member is made small to improve the appearance quality, it is possible to suppress the tilting of the plug connecting device due to the detachment and attachment of the plug.

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

[0020] In this case, while increasing the support stability for the plug connecting device by widening the vertical width of the first coupling portion, it is possible to improve the appearance quality by narrowing the vertical width of the arm portion exposed outside the plug connecting device.

Advantages of the Invention

[0021] In the plug connection fixture according to the present invention, since a coupled portion to which a coupling member is coupled is arranged in a groove portion along the vertical direction, by coupling the coupling member to the coupled portion within the groove portion, it is possible to suppress the increase in size of the coupling member and the external exposure of the coupling portion between the coupling member and the plug connection fixture, while enabling the support structure to be stably supported by the coupling member. Therefore, when the plug connection fixture according to the present invention is adopted, it is possible to enhance the support stability while suppressing the deterioration of the appearance quality.

[0022] Further, in the fixture unit according to the present invention, since a groove portion along the vertical direction is formed on the outer surface of the plug connection fixture and the first coupling portion of the coupling member is coupled to the plug connection fixture within the groove portion, it is possible to suppress the increase in size of the coupling member and the external exposure of the coupling portion between the coupling member and the plug connection fixture, while enabling the plug connection fixture to be stably supported by 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 connection fixture while suppressing the deterioration of the appearance quality.

Embodiments for Carrying Out the Invention

[0024] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the furniture unit 1 of the present embodiment. FIG. 2 is a side view of the furniture unit 1, and FIG. 3 is a partial cross-sectional plan view of the furniture unit 1 with the single chair 51 to be described later removed. In the furniture unit 1 of the present embodiment, a bench 2 as a furniture main body and a plug-connected furniture 3 are integrally coupled by a coupling member 4. The bench 2 is installed on the floor surface F and constitutes a support structure for supporting the plug-connected furniture 3. Hereinafter, the side where a seated person sitting in a regular posture on the bench 2 faces forward is referred to as the front side, the opposite side is referred to as the rear side, and the directions on the left and right of the seated person sitting in a regular posture on the bench 2 are referred to as the left-right direction.

[0025] A plurality of single chairs 51 are supported and fixed to a support rod 50 (beam member) having a rectangular cross-section that extends substantially horizontally in the left-right direction on the bench 2. Legs 52 are attached to both ends of the support rod 50 in the longitudinal direction, and the support rod 50 is installed on the floor surface F via the legs 52. The support rod 50 is formed of a metal material with high rigidity in relation to supporting the plurality of single chairs 51 and the load of the seated person. All the single chairs 51 attached to the support rod 50 have the same structure. Further, armrests 53 supported and fixed to the support rod 50 are arranged on the side portions of each single chair 51.

[0026] The single chair 51 includes a seat 54 that supports the buttocks of the seated person, a backrest 55 that supports the back of the seated person, and a pair of connecting legs 56 that extend downward from the lower surfaces of the left and right side edges of the seat 54 and whose lower end regions are fixed to the support rod 50. A fitting recess (not shown) that opens downward in a substantially U-shape is formed at the lower end of each connecting leg 56, and the fitting recess is fitted to the upper half of the support rod 50.

[0027] The leg body 52 includes a base portion 52a whose upper end is attached to the support rod 50, a front leg 52b and a rear leg 52c that branch and extend forward and backward 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. On the upper surface side of the base portion 52a of the leg body 52, a fitting recess 52a-1 that opens upward is formed, and the fitting recess 52a-1 is fitted to the lower half of the support rod 50. 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 in this state. Also, the connecting leg 56 at the inner end of the single chair 51 at the end and the connecting legs 56 of the remaining single chairs 51 sandwich the support rod 50 between them and a substantially U-shaped receiving fitting 57 that opens upward, and are fixed to the support rod 50 by being bolted to the receiving fitting 57 in this state.

[0028] The plug connection appliance 3 is an appliance provided with a connector block 10 that can insert and remove plugs such as a power plug and communication plugs (for example, a USB plug, a plug for wired LAN connection), and is formed to be long in the vertical direction. The plug connection appliance 3 of the present embodiment includes four similar connector blocks 10. Each connector block 10 has a power plug insertion port 11 to which a power plug is detachably connected on the end face on the side exposed to the outside, and a communication plug insertion port 12 to which a communication plug is detachably connected. In the present embodiment, the power plug insertion port 11 and the communication plug insertion port 12 constitute a plug connection portion.

[0029] The plug connection appliance 3 includes a skeleton member 13 that extends in the vertical direction, a front cover member 14F that covers the front side of the skeleton member 13, and a rear cover member 14R that covers the rear side of the skeleton member 13. Cables (power cables and signal cables) (not shown) that connect to the respective insertion ports 11 and 12 of each connector block 10 are supported by the skeleton member 13. The cables drawn out from below the skeleton member 13 are connected to the power wiring and signal wiring of the facility where the appliance unit 1 is installed. Also, the front cover member 14F and the rear cover member 14R are detachably attached to the skeleton member 13 by screwing or the like.

[0030] Figure 4 is a perspective view of the skeletal member 13 as viewed from the rear side. Figure 5 is a view showing together the front view (a), side view (b), and plan view (c) of the rear cover member 14R. Note that the front cover member 14F has the same structure as the rear cover member 14R. Also, Figure 6 is a cross-sectional view taken along the line VI-VI of Figure 2. As shown in Figure 4, the skeletal member 13 includes 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 spaced apart in the left-right direction on the base plate 13a.

[0031] The base plate 13a is composed of a rectangular metal plate whose front-rear direction is longer than the left-right direction. The left and right side frames 13b have a cross-sectional shape (see Figure 6) obtained by bending a metal plate that is long in the vertical direction a plurality of times in a direction intersecting the vertical direction. A display plate 15 made of acrylic resin or the like is attached to the upper end portions of the left and right side frames 13b. The display plate 15 shows a diagram of a plug or the like so that it can be recognized from the outside that there is a fixture to which a plug can be connected. The connecting frame 13c is formed of a metal plate.

[0032] In the vicinity of the upper end portion on the rear side of the left and right side frames 13b, a metal fixing piece 16 for screwing the rear cover member 14R is installed. Further, below the installation position of the fixing piece 16 in the upper region on the rear side of the left and right side frames 13b, a holding plate 17 for holding the two connector blocks 10 is fixed. The holding plate 17 has a shape in which the central portion in the left - right direction protrudes substantially in a V - shape toward the rear side. The left and right side edges of the holding plate 17 are coupled to the rear surfaces of the left and right side frames 13b. On the left and right inclined walls sandwiching the central top portion of the holding plate 17, fitting and fixing ports 18 for fitting and fixing the corresponding connector blocks 10 are formed respectively. The left and right fitting and fixing ports 18 are formed at different height positions in the vertical direction. Each connector block 10 is fixed to the fitting and fixing port 18 such that the insertion ports 11, 12 face in a direction substantially orthogonal to the inclined wall of the holding plate 17. As a result, the insertion ports 11, 12 of the left connector block 10 on the rear side face obliquely backward to the left, and the insertion ports 11, 12 of the right connector block 10 on the rear side face obliquely backward to the right.

[0033] In FIG. 4, since the skeletal member 13 is viewed from the rear side, the structure on the front side cannot be visually recognized, but the front side of the skeletal member 13 has the same structure as the rear side. On the front side of the left and right side frames 13b, a fixing piece 16 and a holding plate 17 having the same structure as the rear side are attached at the same height position as those on the rear side. The corresponding connector blocks 10 are respectively fitted and fixed to the left and right fitting and fixing ports 18 of the holding plate 17 on the front side. As a result, the insertion ports 11, 12 of the left connector block 10 on the front side face obliquely forward to the left, and the insertion ports 11, 12 of the right connector block 10 on the front side face obliquely forward to the right. Note that each arrow in FIG. 3 indicates the detachment direction of the plug in each of the front - side and rear - side connector blocks 10.

[0034] Further, as shown in FIG. 6, the left and right side frames 13b are formed such that their horizontal cross-sections are substantially hat-shaped. Specifically, the left and right side frames 13b include 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 and extend inward in the left-right direction from the respective end portions on the rear and front sides of the outer wall 13b-1, a rear flange 13b-4 that bends and extends rearward from the inner end portion of the rear wall 13b-2, and a front flange 13b-5 that bends and extends forward from the inner end portion of the front wall 13b-3. The left and right side edges of the above-described rear holding 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 holding 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 FIG. 5, the rear cover member 14R is constituted by a vertically long metal plate that is bent such that the center in the left-right direction protrudes substantially in a V shape toward the rear. Note that the front cover member 14F has the same structure as the rear cover. Therefore, hereinafter, only the detailed structure of the rear cover member 14R will be described, and the description of the detailed structure of the front cover member 14F will be omitted.

[0036] As shown in FIGS. 5 and 6, the rear cover member 14R has inclined walls 14b disposed on both the left and right sides of a top portion 14a that protrudes rearward. At positions corresponding to the left and right fitting and fixing openings 18 of the rear holding plate 17 among the left and right inclined walls 14b, substantially rectangular openings 20 are formed for exposing a part of the end face of the connector block 10 held in each fitting and fixing opening 18 to the outside. The insertion ports 11 and 12 of the end face of each connector block 10 are exposed to the outside of the rear cover member 14R through the openings 20.

[0037] At a plurality of vertically spaced positions inside the rear cover member 14R, reinforcing plates 21 are joined. Each reinforcing plate 21 is joined to the left and right inclined walls 14b inside the rear cover member 14R by welding or the like. At the upper end of the reinforcing plate 21 disposed near the upper end of the rear cover member 14R, a tongue piece 22 protruding rearward is extended. The tongue piece 22 is overlapped on the upper surface of the fixing piece 16 of the skeletal member 13 shown in FIG. 4, and is fastened and fixed to the fixing piece 16 by a screw (not shown). The upper end of the rear cover member 14R is open, and the opening is detachably closed by a separate lid member 23 shown in FIG. 1. The screwing of the tongue piece 22 to the fixing piece 16 is performed through the upper opening before attaching the lid member 23 to the upper end of the rear cover member 14R.

[0038] At the left and right extending ends in the left and right directions of the left and right inclined walls 14b of the rear cover member 14R, as shown in FIG. 6, bent walls 24 that are acutely bent inward in the left and right directions are provided. In a state where the rear cover member 14R is assembled to the skeletal member 13, the tip of the bent wall 24 abuts or is close to the surface of the outer wall 13b-1 of the side frame 13b of the skeletal member 13. As shown in FIG. 6, in a state where the front cover member 14F is assembled to the skeletal member 13, the tip of the bent wall 24 of the front cover member 14F also abuts 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 portion 25 having a substantially U-shaped cross section that opens outward in the left-right direction. The groove portion 25 is formed to extend along the vertical direction on the outer surface of the plug connecting fixture 3. Further, as shown in FIG. 3, the two groove portions 25 on both the left and right sides are formed symmetrically with respect to the center line o1 that connects the top portions 14a of the front cover member 14F and the rear cover member 14R, with their openings facing the opposite left and right sides in the rhombus-shaped horizontal cross section of the plug connecting fixture 3. As shown in FIG. 2, a plurality of pairs of screw holes 27, which are joined portions where the connecting member 4 is joined, are formed at a plurality of locations spaced apart in the vertical direction on the outer wall 13b-1 that forms the bottom surface of each groove portion 25. Therefore, a part of the skeletal member 13 is exposed inside each groove portion 25, and the screw holes 27, which are joined portions, are arranged in the exposed portion.

[0040] In addition, locking claws 26 that protrude toward the front side are provided at one location near the upper end and two locations near the lower end of the extending 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 is screwed to the side frame 13b in that state.

[0041] Note that the base plate 13a at the lower end of the skeletal member 13 shown in FIG. 4 is covered with a base cover 37, which is a decorative plate, as shown in FIGS. 1 to 3.

[0042] FIG. 7 is an enlarged view of part VII of FIG. 1 showing the joining portion of the connecting member 4 on the side of the plug connecting fixture 3. FIG. 8 is a perspective view of the connecting member 4, and FIGS. 8(a) and 8(b) sequentially show the joining procedure of the connecting member 4 to the support rod 50 of the bench 2. Further, FIG. 9 is a perspective view of the connecting member 4, and FIGS. 9(a) and 9(b) sequentially show the assembly procedure of the connecting member 4. In the case of this embodiment, two connecting members 4 having a bilaterally symmetric shape are used. Each connecting member 4 has a first coupling portion 28 coupled to the plug connecting device 3, a second coupling portion 29 coupled to the support rod 50 of the bench 2, and an arm portion 30 coupling the first coupling portion 28 and the second coupling portion 29.

[0043] The first coupling portion 28 is constituted by a rectangular parallelepiped metal block that is long in the vertical direction. The first coupling portion 28 is disposed within the groove portion 25 of the plug connecting device 3. The thickness of the first coupling portion 28 in the left - right direction is set to be substantially the same as the depth of the groove portion 25. Thread holes 31 are formed in the vicinity of each of the upper end portion and the lower end portion of the first coupling portion 28. These thread holes 31 are aligned with a pair of any of the thread holes 27 within the groove portion 25, and fixing screws 32 are inserted as shown in FIG. 7. The first coupling portion 28 is thus coupled within the groove portion 25 of the plug connecting device 3 by tightening the fixing screws 32 into the thread holes 27.

[0044] As shown in FIG. 8, the second coupling portion 29 is composed 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 of metal plates. The upper clamp 29a includes an upper wall 29a - 1 that abuts against the upper surface of the support rod 50, a rear wall 29a - 2 that abuts against the rear surface of the support rod 50, and a front wall 29a - 3 that abuts against the front surface of the support rod 50. The extension length of the rear wall 29a - 2 in the vertical direction is set to be longer than the extension length of the front wall 29a - 3 in the vertical direction. Joining flanges 29a - 4 that bend outward are respectively extended at the lower end of the rear wall 29a - 2 and the lower end of the front wall 29a - 3.

[0045] The lower clamp 29b includes a lower wall 29b - 1 that abuts against the lower surface of the support rod 50, a rear wall 29b - 2 that abuts against the rear surface of the support rod 50, and a front wall 29b - 3 that abuts against the front surface of the support rod 50. The extension length of the front wall 29b - 3 in the vertical direction is set to be longer than the extension length of the rear wall 29b - 2 in the vertical direction. Joining flanges 29b - 4 that bend outward are respectively extended at the lower end of the rear wall 29b - 2 and the lower end of the front wall 29b - 3. The second coupling part 29 is fixed to the support rod 50 of the bench 2 by fitting the upper clamp 29a and the lower clamp 29b onto the support rod 50 of the bench 2 from above and below respectively, and fastening the joining flanges 29a-4 and 29b-4 to each other with screws 33 in that state.

[0046] The arm part 30 is formed of a vertically long metal square tube member. At the rear end part of the arm part 30, the first coupling part 28 is integrally coupled by welding or the like, and at the front end part of the arm part 30, the upper clamp 29a of the second coupling part 29 is detachably coupled by screw fastening (see the screw 34 in Fig. 9) or the like. The arm part 30 has a vertically long cross-sectional shape in which the width in the vertical direction is wider than the width in the left-right direction, but the width in the vertical direction of the arm part 30 is narrower than the width in the vertical direction of the first coupling part 28. Conversely, the width in the vertical direction of the first coupling part 28 is set wider than the width in the vertical direction of the arm part 30. Since the upper clamp 29a of the second coupling part 29 is detachably coupled to the front end part of the arm part 30, it can be replaced with another upper clamp 29a and lower clamp 29b having different sizes and shapes according to the size and shape of the support rod 50 of the object to be attached.

[0047] In the present embodiment, as shown in Fig. 3, two different connecting members 4 are coupled in the left and right groove parts 25 of the plug connection fitting 3. The connecting members 4 coupled in each groove part 25 are arranged in a V shape such that the distance between them gradually widens from the plug connection fitting 3 toward the bench 2 (the fitting main body) in a top view, and in that state, the front end parts are coupled to the support rod 50 of the bench 2.

[0048] As described above, in the plug connection fitting 3 of the present embodiment, a groove portion 25 extending along the vertical direction is formed on the outer surface, and a screw hole 27 (a portion to be coupled) for coupling the first coupling portion 28 of the coupling member 4 is disposed within the groove portion 25. Therefore, by coupling the coupling member 4 to the screw hole portion (portion to be coupled) within the groove portion 25, it is possible to suppress an increase in size of the coupling member 4 and external exposure of the coupling portion between the coupling member 4 and the plug connection fitting 3, while enabling the plug connection fitting 3 to be stably supported by the coupling member 4 on the bench 2. Thus, when the plug connection fitting 3 of the present embodiment is adopted, it is possible to enhance the support stability while suppressing a deterioration in appearance quality.

[0049] Further, the plug connection fitting 3 of the present embodiment includes two groove portions 25 to which different coupling members 4 are coupled, and the two groove portions 25 are formed so that in the horizontal cross-section of the plug connection fitting 3, their openings face opposite sides and are line-symmetrical with respect to each other across the center line o1. Therefore, when the plug connection fitting 3 of the present embodiment is adopted, it is possible to stably support the line-symmetrical positions in the horizontal cross-section of the plug connection fitting 3 by the two coupling members 4.

[0050] Moreover, the plug connection fitting 3 of the present embodiment includes a skeletal member 13 extending in the vertical direction, and a front cover member 14F and a rear cover member 14R detachably attached to the skeletal member 13, and the groove portion 25 is constituted by the skeletal member 13, the front cover member 14F, and the rear cover member 14R. And the screw hole 27 which is the portion to be coupled within the groove portion 25 is formed in the skeletal member 13 portion. Therefore, without removing the coupling member 4 from the plug connection fitting 3, it is possible to perform maintenance inside the plug connection fitting 3 by removing at least one of the front cover member 14F and the rear cover member 14R. Thus, when the plug connection fitting 3 of the present embodiment is adopted, it is possible to improve the workability during maintenance.

[0051] Furthermore, in the plug-connecting fixture 3 of the present embodiment, pairs of screw holes 27, which are the parts to be joined, are formed at a plurality of locations spaced apart in the vertical direction within the groove portion 25, and the first coupling portion 28 of the connecting member 4 can be selectively coupled to any one of the pairs of screw holes 27. Therefore, the height of the coupling portion between the connecting member 4 and the plug-connecting fixture 3 can be changed according to the height of the coupling portion with the connecting member 4 on the bench 2 (support structure, fixture body) side. Thus, when the plug-connecting fixture 3 of the present embodiment is adopted, it can be easily applied to benches 2 (support structures, fixture bodies) of various specifications with different heights of the coupling portion with the connecting member 4.

[0052] Also, in the fixture unit 1 of the present embodiment, two connecting members 4 coupled to different groove portions 25 are arranged in a V shape such that the distance between them gradually widens from the plug-connecting fixture 3 toward the bench 2 (fixture body) in a top view. Therefore, when a plug is detached from or attached to the plug-connecting portion (insertion ports 11, 12) of the plug-connecting fixture 3, the detachment and attachment load of the plug can be stably supported by the bench 2. Thus, when the fixture unit 1 of the present embodiment is adopted, even if each connecting member 4 is made small to improve the appearance quality, it is possible to suppress the tilting of the plug-connecting fixture 3 due to the detachment and attachment of the plug.

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

[0054] Furthermore, in the fixture unit 1 of the present embodiment, the second coupling portion 29 of the connecting member 4 is detachably coupled to the arm portion 30 of the connecting member 4. Therefore, when the fixture unit 1 of the present embodiment is adopted, by replacing the second coupling portion 29 of the connecting member 4 with ones of different sizes and shapes, it is possible to easily cope with various benches 2 (fixture bodies) of different specifications.

[0055] Note that the present invention is not limited to the above-described embodiments, and various design changes are possible without departing from the gist thereof. For example, in the furniture unit 1 of the above-described embodiment, the plug-connected furniture 3 is connected to the bench 2 which is the furniture main body, but the furniture main body constituting the furniture unit is not limited to the bench, and may be other furniture such as a desk or a wagon. Further, in the plug-connected furniture 3 of the above-described embodiment, the front cover member 14F and the rear cover 14B are detachably attached to the front side and the rear side of the frame member 13, respectively, but the cover member may be attached only to either the front side or the rear side of the frame member 13. Also, the support structure that supports the plug-connected furniture via the connecting member is not limited to furniture such as a bench, and may be a wall of a building or the like.
