[0003] [Patent Document 1] Patent No. 6893463 [Patent Document 2] Patent No. 6422184 [Patent Document 3] Patent No. 7243255 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the support needs to have a certain level of strength since items (for example, lighting devices, table taps, etc.) will be attached to it. In this case, if an attempt is made to ensure the strength of the support by, for example, making the entire item support part thicker, this could degrade the appearance of the fixture with a tabletop.

[0005] The present invention provides a display unit with a top plate that can stably support items while improving the appearance. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention employs the following aspects. (1) A fixture with a tabletop according to one embodiment of the present invention comprises a lower structure rising from a floor surface, a tabletop supported from below by the lower structure, and an upper structure having a plurality of upright portions extending upward relative to the tabletop, and connecting rods extending above the tabletop in a transverse direction that intersects the up-down direction and connecting the upper ends of the plurality of upright portions, the connecting rods being provided with reinforcing members extending in the transverse direction and to which optional members can be attached.

[0007] According to this aspect, the upper structure extends above the tabletop, giving the user of the tabletop-equipped furniture a feeling of being surrounded. In addition, by providing a reinforcing member along the connecting rod, the connecting rod can be reinforced by the reinforcing member. This allows the entire upper structure to be made thinner, improving the appearance, and stably supporting optional components.

[0008] (2) In the fixture with a tabletop according to the above aspect (1), it is preferable that the reinforcing member is provided on the outside of the connecting rod. According to this aspect, the reinforcing member can be attached to the connecting rod later, and thus the ease of assembly of the reinforcing member and the degree of freedom in design can be improved.

[0009] (3) In the display fixture with a tabletop relating to the above aspect (2), it is preferable that the optional component includes electrical equipment, and the reinforcing component is electrically connected to the optional component and has a power supply section that supplies power to the optional component. According to this aspect, the upper structure can support electrical equipment, thereby providing a user-friendly fixture with a top plate.

[0010] (4) In the fixture with a tabletop relating to the above-mentioned aspect (3), it is preferable that the reinforcing member is attached to the connecting rod while supporting the power supply unit, and includes a mounting fixture extending in the intersecting direction, and a cover member surrounding the mounting fixture while exposing the power supply unit to the outside. According to this aspect, the appearance of the reinforcing member is improved, and the connecting rod can be reinforced by both the mounting fixture and the cover member.

[0011] (5) In the fixture with a tabletop according to the above aspect (2), it is preferable that the reinforcing member includes a rail member that enables the mounting position of the optional member along the intersecting direction to be changed. According to this aspect, the optional member can be attached to any position on the rail member in the cross direction, thereby improving the usability of the furniture with a tabletop.

[0012] (6) In the fixture with a tabletop according to the aspect (5) above, it is preferable that the optional component is a lighting device and the rail component is a duct rail. According to this aspect, by using the duct rail as the reinforcing member, the lighting device can be supported on the upper structure, which allows the upper surface of the tabletop to be illuminated regardless of the positional relationship between the lighting (e.g., ceiling lighting) installed in the facility itself and the upper structure.

[0013] (7) In the fixture with a tabletop according to the above aspect (5) or (6), it is preferable that the reinforcing member has a rail cover surrounding the rail member. According to this aspect, the connecting rod can be reinforced by both the duct rail and the rail cover.

[0014] (8) In a fixture with a tabletop relating to any one of the above aspects (1) to (6), it is preferable that there are three or more upright portions, the connecting rods extend from the upper ends of each of the upright portions toward the center of the tabletop in a planar view and intersect with each other above the tabletop, and the reinforcing member is arranged to span the intersecting portions of the connecting rods. According to this aspect, by reinforcing the intersection portion of the connecting rod with a reinforcing member, it is easy to increase the strength of the upper structure. Effect of the Invention

[0015] According to each of the above aspects, it is possible to stably support an article while improving the appearance. [Brief description of the drawings]

[0017] Next, an embodiment of the present invention will be described with reference to the drawings. In the embodiments and modifications described below, the same reference numerals may be used to designate corresponding configurations, and the description may be omitted. In the following description, expressions indicating relative or absolute arrangements, such as "parallel," "orthogonal," "center," and "coaxial," not only strictly indicate such arrangements, but also indicate a state in which the two surfaces are relatively displaced with an angle or distance to the extent that the same function is obtained. In this embodiment, "facing" does not only mean a case in which the orthogonal directions (normal directions) of the two surfaces are aligned with each other, but also includes a case in which the orthogonal directions intersect with each other.

[0018] (First embodiment) [Display unit with tabletop 1] Fig. 1 is a perspective view of a tabletop-equipped fixture 1. Fig. 2 is a cross-sectional view corresponding to line II-II in Fig. 1. The tabletop-equipped fixture 1 shown in Figures 1 and 2 is a table installed on the floor surface F of various facilities (for example, an office or public facility). The tabletop-equipped fixture 1 comprises a tabletop 11, a support structure 12, and a lighting unit 13. In the following explanation, the direction perpendicular to the floor surface F will be referred to as the up-down direction (arrow UP indicates the upward direction), and the two directions perpendicular to the up-down direction will be referred to as the front-rear direction (arrow FR indicates the forward direction) and the left-right direction (arrow LH indicates the left side), respectively.

[0019] <Tabletop 11> As shown in FIG. 2, the tabletop 11 has an upper surface and a lower surface that are both flat and arranged parallel to the floor surface F. The tabletop 11 has a square shape in plan view, including a plurality of tabletop corners 11a and tabletop side portions 11b that connect adjacent tabletop corners 11a. Each of the tabletop corners 11a and tabletop side portions 11b is formed in a protruding arc shape that is away from the center O1 of the tabletop 11 in plan view. In the following description, the direction along one of the diagonals of the tabletop 11 (straight lines that pass through the center O1 of the tabletop 11 and connect opposing tabletop corners 11a) in plan view may be referred to as the X-direction, and the direction along the other diagonal may be referred to as the Y-direction.

[0020] FIG. 3 is a cross-sectional view corresponding to line III-III in FIG. 1 and 3, the outer peripheral surface 11c of the top plate 11 is configured to have a uniform shape all around. As shown in Fig. 3, the outer peripheral surface 11c includes an upper flat surface 11c1 and an inclined surface 11c2. The upper flat surface 11c1 extends downward from the outer periphery of the upper surface of the top plate 11. The upper flat surface 11c1 extends linearly in the up-down direction in a cross-sectional view. The inclined surface 11c2 extends downward from the upper flat surface 11c1 toward the center O1 of the tabletop 11 in a plan view. The lower edge of the inclined surface 11c2 is continuous with the outer periphery of the lower surface of the tabletop 11. In the illustrated example, the vertical dimension of the inclined surface 11c2 is larger than that of the upper flat surface 11c1.

[0021] <Support structure 12> FIG. 4 is an exploded perspective view of the support structure 12. As shown in FIG. 4, the support structure 12 includes a lower structure 21 and an upper structure 22.

[0022] <Lower structure 21> FIG. 5 is an enlarged view of FIG. 4 and 5, the lower structure 21 supports the top board 11 from below. Specifically, the lower structure 21 includes an outer peripheral frame 31 and a plurality of support legs 32. The peripheral frame 31 is formed in a polygonal shape (square shape) having the same number of sides as the tabletop side portions 11b in a plan view, and is formed in a frame shape that is slightly smaller than the outer shape of the tabletop 11. The peripheral frame 31 is fixed to the underside of the tabletop 11 at a portion located inside the outer periphery of the tabletop 11. The peripheral frame 31 includes a plurality of beams 35 and corner brackets 36.

[0023] Each beam 35 is formed, for example, with a hat-shaped cross section that opens upward. Each beam 35 is provided corresponding to each tabletop side portion 11b. Each beam 35 extends along the lower surface of the tabletop 11 in the extension direction of the corresponding tabletop side portion 11b (front-rear or left-right direction). Each beam 35 is fixed to the tabletop 11 by fixing each flange portion to the lower surface of the tabletop 11.

[0024] As shown in Fig. 5, the corner brackets 36 are provided at each corner of the outer perimeter frame 31. The corner brackets 36 connect the outer perimeter frame 31 and the upper structure 22 to each other, and connect the outer perimeter frame 31 and the support legs 32 to each other. The corner brackets 36 are integrally formed in an L-shape when viewed from the side. All of the corner brackets 36 have the same configuration. Therefore, the corner brackets 36 will be described in detail below using the corner bracket 36 located on the +X side as an example.

[0025] As shown in FIGS. 3 and 5, the corner bracket 36 includes a frame connecting portion 41, a top board connecting portion 42, a connection portion 43, and a leg connecting portion 44. The frame connecting portion 41 is a portion that connects the corner bracket 36 and the beam 35 together. The frame connecting portions 41 are located between adjacent beams 35 and are connected to each of the adjacent beams 35 .

[0026] The tabletop connecting portion 42 is a portion that connects the corner bracket 36 and the tabletop 11. The tabletop connecting portion 42 is formed in a hexagonal shape in a plan view. Specifically, the tabletop connecting portion 42 extends from the frame connecting portion 41 toward the +X side along the underside of the tabletop 11, and is a portion that is wider on both sides in the Y direction than the frame connecting portion 41. The tabletop connecting portion 42 is located on the -X side with respect to the outer periphery of the tabletop corner portion 11a in a plan view. Therefore, the tabletop connecting portion 42 overlaps with the tabletop 11 in a plan view. The tabletop connecting portion 42 is connected to the underside of the tabletop 11 by a screw or the like that penetrates the tabletop connecting portion 42 from below.

[0027] The connection part 43 connects between the tabletop connector 42 and the leg connector 44. The dimension of the connection part 43 in the Y direction is equal to that of the frame connector 41, and extends from the tabletop connector 42 to the +X side. The +X side end of the connection portion 43 protrudes from the outermost portion of the top plate corner portion 11a toward the +X side. The leg connecting portion 44 is a portion that connects the corner bracket 36 and the support leg 32. The leg connecting portion 44 extends downward from the +X side end of the connection portion 43. Therefore, in a plan view, the leg connecting portion 44 protrudes from the outermost portion of the tabletop corner portion 11a to the +X side. In the illustrated example, the leg connecting portion 44 extends at an angle toward the +X side as it extends downward.

[0028] In the corner bracket 36, a wire passing groove 53 is formed in a portion of the connection portion 43 that overlaps with the top plate 11 in a plan view. The wire passing groove 53 opens on the upper surface of the connection portion 43 and extends in the X direction through the connection portion 43. The +X side end of the wire passing groove 53 is located on the +X side of at least the lower surface of the top plate 11, among the outermost portions of the top plate corner portion 11a. Therefore, the +X side end of the wire passing groove 53 is open upward on the +X side with respect to the lower surface of the top plate 11. In the illustrated example, the +X side end of the wire passing groove 53 is located at the same position as the upper surface of the top plate 11, among the outermost portions of the top plate corner portion 11a. However, the +X side end of the wire passing groove 53 may be located on the +X side or -X side with respect to the upper surface of the top plate 11, among the outermost portions of the top plate corner portion 11a.

[0029] In the corner bracket 36, a wiring outlet hole 54 is formed at the boundary between the top plate connecting portion 42 and the connection portion 43. The wiring outlet hole 54 passes through the corner bracket 36 in the vertical direction. The upper end of the wiring outlet hole 54 communicates with the inside of the wiring passage groove 53. Meanwhile, the lower end of the wiring outlet hole 54 opens at the lower surface of the corner bracket 36.

[0030] A pillar accommodating groove 55 is formed in the corner bracket 36 in a portion extending from the +X side end of the connection portion 43 to the leg connecting portion 44. The pillar accommodating groove 55 opens upward and on the +X side and extends in the vertical direction. Therefore, the pillar accommodating groove 55 opens on the outer surface of the corner bracket 36 (leg connecting portion 44). The upper end of the pillar accommodating groove 55 and the wire passing groove 53 are disposed across a partition wall 56. A communication groove 57 is formed in the partition wall 56 to communicate between the pillar accommodating groove 55 and the wire passing groove 53.

[0031] As shown in Figs. 4 and 5, the support leg 32 is formed in a rod shape extending in the vertical direction. The lower end of the support leg 32 is in contact with the floor surface F. In this embodiment, the support leg 32 extends toward the +X side as it heads downward along the inclination direction of the leg connecting part 44. The support leg 32 is fixed to the lower end of the leg connecting part 44. Specifically, the support leg 32 is fixed to the leg connecting part 44 by a screw or the like penetrating a part of the leg connecting part 44 located in the bottom wall 44a of the support column receiving groove 55. The bottom wall 44a is formed with a recess 58 for receiving the head of the screw.

[0032] <Superstructure 22> 1, the upper structure 22 surrounds the side and top of the tabletop 11. The upper structure 22 includes a plurality of support columns 61 and a connecting bar (connecting rod) 62. As shown in FIGS. 4 and 5, each of the pillars 61 is fixed to each of the leg connectors 44 . Since each of the pillars 61 has the same configuration, the following description will be given in detail of the pillar 61 by taking the pillar 61 located on the +X side as an example.

[0033] The support pillar 61 has a vertical rod (standing portion) 61a and a horizontal rod (connecting rod) 61b, and is formed in an L-shape in a side view. The vertical rod 61a is formed in a square tube shape with the Y direction as the longitudinal direction and the X direction as the transverse direction. The vertical rod 61a extends in the vertical direction on the side of the tabletop 11 (the portion facing the outermost part of the tabletop corner portion 11a in the X direction). The lower end of the support column 61 is fixed to the leg connecting portion 44 below the tabletop 11. Specifically, the vertical rod 61a is fitted into the support column receiving groove 55 from the +X side and detachably fixed to the leg connecting portion 44 by a screw or the like penetrating the leg connecting portion 44 from the -X side. In this case, the outer surface of the vertical rod 61a is disposed flush with the outer surfaces of the support leg 32 and the leg connecting portion 44.

[0034] The vertical rod 61a passes through the side of the tabletop 11 and protrudes upward from the upper surface of the tabletop 11. Specifically, the vertical rod 61a extends at an incline toward the -X side as it goes upward along the inclination direction of the support leg 32. The upper end of the vertical rod 61a is located on the -X side (inner side) of the tabletop corner portion 11a in a plan view. However, the entire vertical rod 61a may be located on the +X side of the tabletop corner portion 11a.

[0035] As shown in FIG. 3, a communication space S1 is formed in the area surrounded by the vertical rod 61a, the connection portion 43, and the inclined surface 11c2 of the top plate 11. The communication space S1 is a triangular space whose size gradually decreases in the X direction as it goes upward when viewed from the Y direction. The upper end of the communication space S1 is closed by the inner wall portion 61a1 located on the -X side of the vertical rod 61a approaching or abutting the upper flat surface 11c1. On the other hand, the lower end of the communication space S1 communicates with the inside of the wire passing groove 53 through the +X side end of the upper end opening of the wire passing groove 53 or the communication groove 57.

[0036] A drawer opening 61c is formed in a portion of the vertical rod 61a that is located below the upper surface of the top plate 11. The drawer opening 61c penetrates an inner wall portion 61a1 of the vertical rod 61a in the X direction. The drawer opening 61c is a long hole extending in the vertical direction. In the illustrated example, the upper end edge of the drawer opening 61c is located below the upper flat surface 11c1. Meanwhile, the lower end edge of the drawer opening 61c is located below the lower surface of the top plate 11. Therefore, the inside of the vertical rod 61a communicates with the communication space S1 through the drawer opening 61c.

[0037] As shown in Figs. 1 and 2, the horizontal rod 61b is connected to the upper end of the vertical rod 61a as a single unit. The horizontal rod 61b is formed in a square tube shape with a rectangular cross section, similar to the vertical rod 61a. The horizontal rod 61b extends upward from the upper end of the vertical rod 61a while curving toward the -X side, and then extends linearly toward the -X side. The horizontal rods 61b of the columns 61 facing each other in the X direction and the horizontal rods 61b of the columns 61 facing each other in the Y direction face each other across the center O1 of the tabletop 11 in a plan view.

[0038] As shown in Fig. 4, an insertion portion 61b1 is formed at the tip end (-X side end) of the horizontal rod 61b. The insertion portion 61b1 is formed in a U-shape that opens downward when viewed from the X direction. The insertion portion 61b1 protrudes toward the -X side from the tip end of the horizontal rod 61b.

[0039] The connecting bar 62 connects the horizontal bars 61b of each support 61 above the tabletop 11. In a plan view, the connecting bar 62 is formed in an X shape that intersects at the center O1 of the tabletop 11. Specifically, the connecting bar 62 includes a bridging bar 71, a first dividing bar 72, and a second dividing bar 73. The bridging bar 71 is formed in a square tube shape with a rectangular cross section, similar to the horizontal bars 61b. The bridging bar 71 connects the horizontal bars 61b of the columns 61 facing each other in the X direction. Specifically, the insertion portion 61b1 of the horizontal bars 61b is inserted into the bridging bar 71. The bridging bar 71 is connected to the cross rod 61b via the insertion portion 61b1 by being fastened to the insertion portion 61b1 with a screw or the like.

[0040] The center of the bridging bar 71 in the X direction overlaps with the center O1 of the tabletop 11 in a plan view. The inside of the bridging bar 71 and the inside of the supporting column 61 facing it in the X direction communicate with each other and function as a wiring insertion space S2 through which wiring can be inserted.

[0041] The first dividing bar 72 connects between the horizontal rod 61b of the support 61 located on the +Y side and the bridging bar 71. The second dividing bar 73 connects between the horizontal rod 61b of the support 61 located on the -Y side and the bridging bar 71. In the upper structure 22, the horizontal rod 61b and the connecting bar 62 form a connecting rod that connects the upper ends of the vertical rods 61a to each other in the space above the top board 11.

[0042] The sides of the table top 11 are surrounded by vertical rods 61a in the portions corresponding to the table top corners 11a, and the top of the table top 11 is surrounded by horizontal rods 61b and connecting bars 62 in the portions located diagonally above the table top 11. Therefore, the table top side portions 11b are open in the front-to-rear direction (or left-to-right direction) between adjacent vertical rods 61a, and are open upward between adjacent horizontal rods 61b.

[0043] 3 and 5, each communication space S1 is provided with a wiring cover 77. For example, the wiring cover 77 provided in the +X side communication space S1 is formed in a triangular shape when viewed from the Y direction, and is open downward and toward the +X side. In the communication space S1, the outlet 61c and the upper end opening of the wiring passage groove 53 communicate with each other through the inside of the wiring cover 77.

[0044] <Lighting unit 13> FIG. 6 is a perspective view of the upper structure 22 seen from below with the lighting device 84 removed. 1 and 6, the lighting unit 13 is suspended from a connecting bar 62 and illuminates the upper surface of the tabletop 11. The lighting unit 13 includes a reinforcing member 70, a plug 83, and a lighting device 84.

[0045] FIG. 7 is a cross-sectional view taken along line VII-VII in FIG. As shown in Figures 6 and 7, the reinforcing member 70 externally reinforces the horizontal bars 61b that face each other in the X direction and the bridging bar 71 (hereinafter simply referred to as the horizontal bars 61b and the bridging bar 71), and also has a lighting device 84 attached as an optional member. The reinforcing member 70 includes a mounting fixture 80, a duct rail 81, and a rail cover 82.

[0046] As shown in FIG. 6, the fixture 80 has a top wall 80a and a side wall 80b, and is formed in a U-shape that opens downward. The fixture 80 extends in the X direction with the top wall 80a facing the lower surface of the horizontal rod 61b and the bridging bar 71. That is, the center of the fixture 80 in the X direction crosses the intersection of the bridging bar 71 and the dividing bars 72 and 73 of the connecting bar 62 (the portion that overlaps with the center O1 in a plan view). In addition, both ends of the fixture 80 in the X direction are arranged to straddle the boundary between the horizontal rod 61b and the bridging bar 71 in the X direction. The fixture 80 is fixed to the horizontal rod 61b by fastening the portion of the top wall 80a located outside the bridging bar 71 in the X direction to the horizontal rod 61b with a screw or the like.

[0047] As shown in FIG. 7, the duct rail 81 includes an exterior rail 130 and a support rail 131. The exterior rail 130, like the fixture 80, is U-shaped and opens downward, and extends in the X direction. That is, the center of the exterior rail 130 in the X direction crosses the intersection (the portion overlapping the center O1 in a plan view) of the bridging bar 71 and the dividing bars 72 and 73 of the connecting bar 62. The exterior rail 130 is fixed to the fixture 80 while being accommodated inside the fixture 80. In this embodiment, the exterior rail 130 is formed, for example, by extruding a metal material. The fixture 80 is not an essential component, and the duct rail 81 may be fixed directly to the cross bar 61b or the bridging bar 71 without the fixture 80.

[0048] A pair of support rails 131 are provided in the exterior rail 130, facing each other in the Y direction. The support rails 131 are formed by extruding an insulating material such as a resin material. Each support rail 131 extends in the X direction over the entire area of ​​the exterior rail 130. An electrode holding groove 131a is formed on the surfaces of each support rail 131 facing each other in the Y direction. An electrode plate 132 is provided in the electrode holding groove 131a. The electrode plate 132 is a plate-like plate with the Y direction as its thickness direction, and extends in the X direction within the electrode holding groove 131a. In addition, a plug support groove 130a is formed in a portion of the exterior rail 130 between the bottom wall of the exterior rail 130 and the support rail 131. The plug support groove 130a extends in the X direction below the electrode holding groove 131a, similar to the electrode holding groove 131a.

[0049] The wiring 81a shown in FIG. 6 is connected to the end of the electrode plate 132 in the X direction. The wiring 81a extending from the duct rail 81 is drawn into the wiring insertion space S2 through a through hole 61b2 formed in the horizontal rod 61b (the horizontal rod 61b arranged on the +X side with respect to the bridging bar 71). Specifically, the through hole 61b2 penetrates a portion of the lower wall part of the horizontal rod 61b located on the +X side with respect to the mounting fixture 80 in the vertical direction. The wiring 81a is routed through the inside of the horizontal rod 61b (the wiring insertion space S2) toward the +X side through the through hole 61b2. The wiring 81a that has passed through the inside of the horizontal rod 61b is guided downward inside the vertical rod 61a. As shown in FIG. 3, the wiring 81a guided inside the vertical rod 61a is drawn into the wiring cover 77 in the communication space S1 through the draw-out port 61c, and then passes through the wiring cover 77. Thereafter, the wiring 81a is guided into the wiring passing groove 53 through the communication groove 57 or the upper end opening of the wiring passing groove 53. After passing through the wiring passing groove 53, the wiring 81a is pulled out into the space below the top plate 11 through the wiring pull-out hole 54. The wiring 81a pulled out into the space below the top plate 11 is connected to an external power source (not shown) or the like.

[0050] 1, the rail cover 82 is formed in a tubular shape whose length in the X direction is longer than the mounting fixture 80 and the duct rail 81. The rail cover 82 is attached to the horizontal rod 61b in a state in which it surrounds the periphery of the mounting fixture 80 and the duct rail 81 together.

[0051] FIG. 8 is an exploded perspective view of the rail cover 82. As shown in FIG. As shown in FIGS. 7 and 8, the rail cover 82 includes a first cover body 100 and a second cover body 101 disposed on both sides of the bridging bar 71 in the Y direction.

[0052] The first cover body 100 is formed in a C-shape when viewed from the X-direction. Specifically, the first cover body 100 includes a first top wall portion 100a, a first side wall portion 100b, a bottom wall portion 100c, and a rising portion 100d. The first top wall portion 100a extends in the X direction along the upper surfaces of the horizontal rod 61b and the bridging bar 71. The first top wall portion 100a is overlapped with the horizontal rod 61b and the bridging bar 71 from above. The width of the first top wall portion 100a in the Y direction is approximately half that of the horizontal rod 61b and the bridging bar 71. As shown in FIG. 8, first slits 100a1 are formed at both ends of the first top wall portion 100a in the X direction. The first slits 100a1 penetrate the first top wall portion 100a in the up-down direction and extend in the X direction.

[0053] As shown in Figs. 7 and 8, the first side wall 100b covers the bridging bar 71, the horizontal rod 61b, the mounting fixture 80, and the duct rail 81 from the +Y side. The first side wall 100b extends downward from the +Y side edge of the first top wall 100a. The lower edge of the first side wall 100b is located below the duct rail 81. A first recess 100e is formed in the center of the first cover body 100 in the X direction so as to straddle the first top wall 100a and the first side wall 100b. The first dividing bar 72 is housed inside the first recess 100e.

[0054] As shown in Fig. 6, the bottom wall portion 100c extends in the X direction along the horizontal rod 61b and the bridging bar 71 below the horizontal rod 61b and the bridging bar 71. The bottom wall portion 100c covers the duct rail 81 from below, straddling the boundary portion between the horizontal rod 61b and the bridging bar 71 in the X direction. The bottom wall portion 100c of this embodiment covers the through hole 61b2 from below. Specifically, the bottom wall portion 100c includes a flat wall 100c1 and an inclined wall 100c2.

[0055] The flat wall 100c1 extends from the lower edge of the first side wall portion 100b to the -Y side. An exposure opening 100c3 is formed in at least the center of the flat wall 100c1 in the X direction. The exposure opening 100c3 exposes at least a part of the duct rail 81 downward. The exposure opening 100c3 can be formed in any position of the bottom wall portion 100c. The inclined walls 100c2 are connected to both end edges of the flat wall 100c1 in the X direction. The inclined wall 100c2 is inclined upward as it moves away from the flat wall 100c1 in the X direction. The tip end (the outer end in the X direction) of the inclined wall 100c2 is close to or in contact with the lower surface of the horizontal rod 61b.

[0056] The rising portion 100d extends upward from the -Y side edge of the flat wall 100c1.

[0057] 7 and 8, the second cover body 101 is formed in an L-shape when viewed from the X direction. Specifically, the second cover body 101 includes a second top wall portion 101a and a second side wall portion 101b. The second top wall portion 101a is disposed adjacent to the first top wall portion 100a in the Y direction above the horizontal rod 61b and the bridging bar 71. The second top wall portion 101a extends in the X direction along the horizontal rod 61b and the bridging bar 71, and overlaps the horizontal rod 61b and the bridging bar 71 from above. The second top wall portion 101a is formed with a width in the Y direction that is approximately half that of the horizontal rod 61b and the bridging bar 71. As shown in FIG. 8, the second top wall portion 101a has second slits 101a1 formed at the same positions in the X direction as the first slits 100a1. The second slits 101a1 penetrate the second top wall portion 101a in the vertical direction and extend in the X direction.

[0058] As shown in Figs. 7 and 8, the second side wall 101b covers the bridging bar 71, the horizontal bar 61b, and the duct rail 81 from the -Y side. The second side wall 101b extends downward from the -Y side edge of the second top wall 101a. The lower end of the second top wall 101a overlaps the rising portion 100d from the -Y side. This allows the rail cover 82 to surround the mounting fixture 80 and the duct rail 81 together. A second recess 101e is formed in the center of the second cover body 101 in the X direction so as to straddle the second top wall 101a and the second side wall 101b. The second dividing bar 73 is housed in the second recess 101e.

[0059] 8, the rail cover 82 is provided with connectors 103 that connect the first cover body 100 and the second cover body 101 to each other. The connectors 103 are provided at both ends of the rail cover 82 in the X direction. Each connector 103 has a first protruding piece 103a and a second protruding piece 103b, and a connection piece 103c that connects the upper ends of the protruding pieces 103a, 103b to each other, and is formed in a U-shape that opens downward.

[0060] A first insertion hole 61b3 is formed in the upper wall portion of the horizontal rod 61b at a position overlapping the first slit 100a1 in a plan view, and a second insertion hole 61b4 is formed in a position overlapping the second slit 101a1 in a plan view. In the connector 103, the first protruding piece 103a is inserted into the first slit 100a1 and the first insertion hole 61b3, and the second protruding piece 103b is inserted into the second slit 101a1 and the second insertion hole 61b4. In this way, the connector 103 connects the cover bodies 100, 101 to each other and connects the rail cover 82 to the horizontal rod 61b.

[0061] FIG. 9 is a cross-sectional view corresponding to the line IX-IX in FIG. As shown in Fig. 9, the plug 83 is attached to the duct rail 81 through the exposure port 100c3. As shown in Fig. 7, the plug 83 includes a plug body 83a, a mounting base 83b, a mounting flange 83c, and an electrode 83d.

[0062] The plug body 83a is formed in a box shape in which wiring, a board, and the like connected to the lighting device 84 are housed. The mounting base 83b protrudes upward from the plug body 83a. The mounting flanges 83c protrude from the mounting base 83b in one direction among directions intersecting the up-down direction. The mounting flanges 83c are accommodated in the plug support groove 130a and are supported from below by the bottom wall of the exterior rail 130. The electrodes 83d protrude in a pair above the mounting flange 83c in the same direction as the mounting flange 83c. The electrodes 83d are housed in the electrode holding groove 131a when the mounting flange 83c is fitted into the plug support groove 130a. The electrodes 83d are connected to the electrode plates 132 in the electrode holding groove 131a. This allows power to be supplied to the lighting device 84 via the duct rail 81 and the plug 83. In the illustrated example, the plug 83 is attached to a portion of the duct rail 81 that overlaps with the center O1 of the top plate 11 in a plan view. However, the plug 83 can be attached to any position of the duct rail 81 in the X direction.

[0063] 1 and 9, the lighting device 84 is suspended from a plug 83. The lighting device 84 includes a lighting body 91 and spoke portions 92. The lighting body 91 is formed in a square frame shape in a plan view. That is, the lighting body 91 is formed in a similar shape to the tabletop 11 but reduced in size. The spokes 92 connect opposite corners of the lighting body 91, respectively, and are formed in an X shape intersecting at the center O2 of the lighting body 91. The spokes 92 are suspended from the plug 83 via a wire 94. As shown in FIG. 2, the lighting body 91 is disposed with the center O2 in a plan view aligned with the center O1 of the tabletop 11.

[0064] A light-emitting unit 97 is housed within the lighting body 91. The light-emitting unit 97 is composed of, for example, an LED or an organic EL. Light emitted from the light-emitting unit 97 is irradiated onto the upper surface of the tabletop 11. A wiring 83a extending from a plug 83 is drawn into the lighting body 91.

[0065] Next, a method of using the display unit with tabletop 1 will be described. In the tabletop-equipped furniture 1 of this embodiment, as shown in Fig. 1, the tabletop side portion 11b is open between adjacent supports 61. Therefore, a user of the tabletop-equipped furniture 1 can perform work on the upper surface of the tabletop 11 while facing either the tabletop side portion 11b facing the front-rear or left-right direction.

[0066] Here, in the tabletop-equipped fixture 1 of this embodiment, the sides and the top of the tabletop 11 are simply surrounded in a frame by the upper structure 22. Therefore, the atmosphere within the facility in which the tabletop-equipped fixture 1 is installed is not impaired (while maintaining a certain sense of openness), and a certain sense of enclosure can be given to users of the tabletop-equipped fixture 1. Therefore, when users facing adjacent tabletop sides 11b work individually, the support pillars 61 are arranged between the adjacent tabletop sides 11b, so that the space each user can use on the upper surface of the tabletop 11 is roughly clear. Also, the upper structure 22 adds a feeling of enclosure to the tabletop-equipped furniture 1, so that users are less likely to be bothered by the gaze of third parties passing around the tabletop-equipped furniture 1. Therefore, workers working individually can concentrate on their respective tasks. On the other hand, since the entire top surface of the tabletop 11 is open and flat, when multiple users work together to perform a task, they can use the entire top surface of the tabletop 11 without being obstructed. Therefore, multiple users using the same tabletop-equipped furniture 1 can be given a sense of being surrounded by the upper structure 22, and can be encouraged to work as a group with a sense of unity.

[0067] In this manner, in the tabletop-equipped fixture 1 of this embodiment, the horizontal rod 61b and the bridging bar 71 are provided with the reinforcing member 70 that extends in the X direction (the intersecting direction) and to which the lighting device 84 can be attached. According to this configuration, the upper structure 22 extends above the tabletop 11, giving a feeling of being surrounded to the user using the tabletop-equipped fixture 1. Furthermore, by providing reinforcing members 70 along the horizontal rods 61b and the bridging bars 71, the horizontal rods 61b and the bridging bars 71 can be reinforced by the reinforcing members 70. This allows the overall upper structure 22 to be made thinner, improving the appearance, while also allowing optional components such as the lighting device 84 to be stably supported.

[0068] In the tabletop-equipped fixture 1 of this embodiment, the reinforcing member 70 is provided on the lower surface (outer surface) of the horizontal rod 61b and the bridging bar 71. According to this configuration, the reinforcing member 70 can be attached to the horizontal rod 61b and the bridging bar 71 later, and the ease of assembly of the reinforcing member 70 and the degree of freedom in design can be improved.

[0069] In the tabletop-equipped fixture 1 of this embodiment, the reinforcing member 70 includes a duct rail 81. According to this configuration, the plug 83 of the lighting device 84 can be attached to any position in the X direction on the duct rail 81. This can improve the usability of the furniture 1 with a top plate.

[0070] As in the tabletop-equipped fixture 1 of this embodiment, by using a duct rail 81 as the reinforcing member 70, the lighting device 84 can be supported on the upper structure 22. This makes it possible to illuminate the top surface of the tabletop 11 regardless of the positional relationship between the lighting (e.g., ceiling lighting) provided in the facility itself and the upper structure 22.

[0071] In the tabletop-equipped fixture 1 of this embodiment, the reinforcing member 70 is configured to include a rail cover 82 that surrounds the periphery of the duct rail 81. According to this configuration, the bridging bar 71 and the cross bar 61b can be reinforced by both the duct rail 81 and the rail cover 82.

[0072] In the display unit 1 with a tabletop of this embodiment, the bridge bar 71 and dividing bars 72, 73 of the connecting bar 62 extend so as to intersect above the tabletop 11, and the reinforcing member 70 is arranged to straddle the intersecting portion of the connecting bar 62. According to this configuration, the intersecting portions of the connecting bars 62 are reinforced by the reinforcing members 70, which makes it easier to increase the strength of the upper structure 22.

[0073] Second embodiment 10 is a perspective view of the upper structure 22 viewed from below. The second embodiment is different from the first embodiment in that a hook ceiling 200 is used instead of the duct rail 81 as a power supply unit that supplies power to the lighting device 84. In the tabletop-equipped fixture 1 shown in FIG. 10, the reinforcing member 70 includes a mounting fixture 80, a hook ceiling (power supply section) 200, and a cover member 201.

[0074] As in the first embodiment, the mounting fixture 80 is formed in a U-shape that opens downward and extends in the X-direction. The mounting fixture 80 is fixed to the horizontal rod 61b by fastening a portion of the top wall portion 80a, which is located on the outer side in the X-direction with respect to the bridging bar 71, to the horizontal rod 61b with a screw or the like.

[0075] The hook-on ceiling 200 is a member for mechanically and electrically connecting the lighting device 84 to the reinforcing member 70. The hook-on ceiling 200 is attached to the top wall 80a from below, with a part of it housed inside the fixture 80. The plug-in part 200a is opened on the lower surface of the hook-on ceiling 200. In this embodiment, a plurality of the hook-on ceilings 200 (for example, three) are provided at intervals in the X direction. However, any number of the hook-on ceilings 200 can be provided at any position in the X direction relative to the fixture 80. A wiring 81a is connected to each hook-on ceiling 200, for example, through the inside of the horizontal rod 61b. As in the first embodiment described above, the wiring 81a is drawn into the wiring insertion space S2 through the through hole 61b2 and then connected to an external power source (not shown) or the like.

[0076] FIG. 11 is a cross-sectional view taken along line XI-XI of FIG. As shown in FIG. 10 and FIG. 11, the cover member 201 is attached to the horizontal rod 61b in a state in which it surrounds the periphery of the mounting tool 80 and the hook-on ceiling 200 together. The cover member 201 includes a first cover body 100 and a second cover body 101, which are disposed on both sides of the bridging bar 71 in the Y direction, similar to the above-mentioned rail cover 82. In the cover member 201, an exposure opening 201a is formed in the flat wall 100c1 of the first cover body 100. The exposure opening 201a exposes at least the lower surface (insertion portion 200a) of the hook-on ceiling 200 to the outside of the cover member 201. Specifically, the exposure opening 201a is formed in the flat wall 100c1 at a position that overlaps with each hook-on ceiling 200 in a plan view.

[0077] The lighting device 84 is suspended from at least one of the hook-up ceiling fixtures 200 via a plug 83. In the illustrated example, the plug 83 is attached to the hook-up ceiling fixture 200 located at the intersection of the connecting bars 62 in a plan view. Specifically, the plug 83 is attached to the hook-up ceiling fixture 200 by being inserted into the hook-up ceiling fixture 200 via the insertion portion 200a. The plug 83 is also electrically connected to the hook-up ceiling fixture 200 by being connected to an electrode (not shown) inside the hook-up ceiling fixture 200. As a result, power is supplied to the lighting device 84 via the hook-up ceiling fixture 200 and the plug 83.

[0078] In this embodiment, the reinforcing member 70 is configured to include a hook ceiling 200. According to this configuration, a lighting device (electrical equipment) 84 can be supported as an optional member on the upper structure 22. This makes it possible to illuminate the upper surface of the tabletop 11 regardless of the positional relationship between the lighting (e.g., ceiling lighting) provided in the facility itself and the upper structure 22. As a result, a user-friendly tabletop-equipped fixture 1 can be provided.

[0079] In this embodiment, the reinforcing member 70 is attached to the connecting bar (connecting rod) 62 while supporting the hook-on ceiling 200, and is configured to include a mounting fixture 80 extending in the X direction and a cover member 201 that surrounds the mounting fixture 80 with the hook-on ceiling 200 exposed to the outside. According to this configuration, the appearance of the reinforcing member 70 can be improved, and the connecting bar 62 can be reinforced by both the mounting fixture 80 and the cover member 201.
