Description

[Technical field]

[0001] The present invention relates to a display unit with a tabletop. [Background technology]

[0002] In a display unit with a tabletop, a configuration is disclosed in which an article support part is provided above the tabletop to improve convenience. For example, the following Patent Documents 1 and 2 disclose a configuration including a support column extending upward from the upper surface of the tabletop and a support member extending from the upper end of the support column along the upper surface of the tabletop to support an article. [Prior art documents] [Patent documents]

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

[0004] However, in the above-mentioned conventional technology, since the support pillars are provided within the plane of the upper surface of the tabletop, there is a problem in that the working area on the upper surface of the tabletop is narrowed.

[0005] The present invention provides a furniture unit with a top that makes it easy to ensure a work area on the upper surface of the top, even when an item support section is provided. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention employs the following aspects. (1) A display unit with a top plate according to one embodiment of the present invention comprises a lower structure rising from a floor surface, a top plate supported from below by the lower structure, a connecting portion connected to the underside of the top plate, a support member extending from the connecting portion along the underside of the top plate and having an extension portion that protrudes from the outer periphery of the top plate in a plan view, and an upper structure that is removably attached to the extension portion and extends above the top plate, with an item being supported on a portion located above the top plate.

[0007] According to this aspect, since the upper structure is attached to the extension that protrudes from the outer periphery of the tabletop, it is easier to secure a work area on the upper surface of the tabletop, compared to, for example, a case in which the upper structure protrudes from the top surface of the tabletop. Furthermore, since the upper structure is detachably attached to the extension, it is easier to load and unload parts, compared to a configuration in which the upper structure and the support member are integrally formed. Therefore, it is possible to improve the work efficiency during assembly. In addition, since the upper structure is detachably attached to the extension, it is possible to flexibly change the form of the tabletop-equipped furniture depending on whether the upper structure is required or not.

[0008] (2) In the display fixture with a tabletop relating to the above aspect (1), it is preferable that the upper structure has an upright portion extending upward from the extension portion and an item support portion extending from the upper end of the upright portion in a cross direction that intersects the up-down direction. According to this aspect, since the article support portion extends in the intersecting direction, an article can be placed at any position in the intersecting direction.

[0009] (3) In the display unit with a tabletop according to the above aspect (1) or (2), it is preferable that the support member is integrally formed with the lower structure. According to this aspect, since the support member and the lower structure are integrally provided, the structure can be simplified and the cost can be reduced compared to a structure in which the support member and the lower structure are provided separately. Also, by making the support member a part of the lower structure, the strength of the lower structure as a whole to support the upper structure can be ensured. Therefore, the upper structure can be stably supported with a simpler structure compared to a case in which the strength of the support member alone to support the upper structure is ensured.

[0010] (4) In a fixture with a tabletop relating to any one of the above aspects (1) to (3), it is preferable that the support members are arranged at intervals along the outer peripheral edge of the tabletop, the upper structure includes pillars respectively attached to the extension portions of the support members, and the pillars attached to the support members are connected to each other above the tabletop. According to this embodiment, it is easier to ensure the strength of the upper structure, and it is possible to improve the degree of freedom in terms of the size and weight of the items supported by the upper structure. Moreover, since the sides and the top of the tabletop are surrounded by the upper structure, it is possible to give a feeling of being surrounded to the users of the tabletop-equipped furniture. This allows both individual work and group work to be carried out efficiently.

[0011] (5) In the fixture with a tabletop relating to any one of the above aspects (1) to (4), it is preferable that the extension portion has a recess that is open upward and to the sides, and the lower end portion of the upper structure is fitted into the recess. According to this aspect, the ease of assembly between the extension portion and the support can be improved.

[0012] (6) In the fixture with a tabletop according to any one of the above aspects (1) to (5), it is preferable that a wiring insertion space through which wiring can pass is formed inside the upper structure. According to this aspect, even if electrical equipment is installed on the upper structure as an item, the wiring can be routed downward without being exposed to the outside of the upper structure, thereby improving the appearance of the fixture with a top plate. Effect of the Invention

[0013] According to each of the above aspects, even when an upper structure is provided, it is easy to ensure a work area on the upper surface of the tabletop. [Brief description of the drawings]

[0015] 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.

[0016] [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.

[0017] <Tabletop 11> As shown in FIG. 2, the tabletop 11 has an upper surface and a lower surface that are both flat and parallel to a floor surface F. The tabletop 11 has a square shape in plan view, and includes 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 directed away from the center O1 of the tabletop 11 in plan view. The radius of curvature of the tabletop corners 11a is smaller than the radius of curvature of the tabletop side portions 11b. The tabletop corners 11a are located closer to the center O1 of the tabletop 11 than the corners formed by connecting tangents (e.g., tangents L1 and L2) that pass through the outermost portions of adjacent tabletop side portions 11b in plan view. In the following description, in a plan view, the direction along one of the diagonals of the tabletop 11 (straight lines passing through the center O1 of the tabletop 11 and connecting opposing tabletop corner portions 11a) may be referred to as the X-direction, and the direction along the other diagonal may be referred to as the Y-direction.

[0018] FIG. 3 is a cross-sectional view taken along 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 vertical 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.

[0019] <Support structure 12> FIG. 4 is a 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.

[0020] <Lower structure 21> FIG. 5 is an exploded perspective view of the support structure 12. 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.

[0021] 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.

[0022] 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.

[0023] 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. The frame connecting portion 41 is located between adjacent beams 35 and is connected to each of the adjacent beams 35.

[0024] 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.

[0025] The connection part 43 connects between the tabletop connecting part 42 and the leg connecting part 44. The dimension of the connection part 43 in the Y direction is equal to that of the frame connecting part 41, and extends from the tabletop connecting part 42 to the +X side. The +X side end part of the connection part 43 protrudes from the outermost part of the tabletop corner part 11a to 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] <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 62. 4 and 5, each support pillar 61 is fixed to each leg connecting portion 44. Since each support pillar 61 has the same configuration, the following description will explain the details of support pillar 61 by taking the support pillar 61 located on the +X side as an example.

[0031] The support pillar 61 has a vertical rod 61a and a horizontal 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.

[0032] 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.

[0033] 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.

[0034] 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 that extends 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.

[0035] 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.

[0036] 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 connects the horizontal rods 61b of the pillars 61 facing each other in the X direction. The bridging bar 71 is formed in a square tube shape with a rectangular cross section, similar to the horizontal rods 61b. The center part 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 pillars 61 facing each other in the X direction communicate with each other and function as a wiring insertion space S2 through which wiring can be inserted.

[0037] 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 column 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 constitute an article support section that supports articles in the space above the top board 11.

[0038] 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.

[0039] Here, as shown in FIG. 2, the tabletop side portion 11b is located on the opposite side of the center O1 of the tabletop 11 in plan view with respect to a virtual line Q1 that connects the vertical rods 61a located on both sides of the tabletop side portion 11b at the top surface position of the tabletop 11. Specifically, the entire tabletop side portion 11b is located outside the virtual line Q1. In this case, the portion of the tabletop 11 that is located outside the virtual line Q1 constitutes a bulging portion 11d. The bulging portion 11d bulges in an arc shape in a direction away from the center O1 of the tabletop 11. In the illustrated example, the virtual line Q1 is a straight line connecting the outermost parts (centers on the outer side surface) of the vertical rods 61a. However, the virtual line Q1 may be a straight line connecting the innermost parts (centers on the inner side surface) of the vertical rods 61a.

[0040] Furthermore, the table top side 11b is located on the opposite side of the table top 11 from the center O1 of the table top 11 in plan view with respect to an imaginary line Q2 that connects the lower ends of the support legs 32 located on both sides of the table top side 11b. However, the table top side 11b may be located closer to the center O1 of the table top 11 in plan view with respect to the imaginary line Q2.

[0041] 3 and 5, each communication space S1 is provided with a wiring cover 77. Since each wiring cover 77 has the same configuration, the following description will explain the details of the wiring cover 77 by taking the wiring cover 77 provided in the +X side communication space S1 as an example.

[0042] The wiring cover 77 is formed in a triangular shape when viewed from the Y direction, and is open downward and toward the +X side. Specifically, the wiring cover 77 includes a side wall portion 77a and a top wall portion 77b.

[0043] The side wall portion 77a is a triangular plate-like shape when viewed from the Y direction. The side wall portion 77a is disposed on the upper surface of the connection portion 43 at both sides of the wire passage groove 53 in the Y direction. This closes both ends of the communication space S1 in the Y direction. The upper end edge of the side wall portion 77a extends along the inclined surface 11c2 while being in close proximity to the inclined surface 11c2. Meanwhile, the +X side end edge of the side wall portion 77a extends along the inner wall portion 61a1 while being in contact with the inner wall portion 61a1 of the vertical rod 61a. The uppermost end (the boundary portion between the upper end edge and the +X side end edge) of the side wall portion 77a is located above the outlet 61c.

[0044] The top wall portion 77b bridges between the upper edges of the side wall portions 77a. The top wall portion 77b extends along the inclined surface 11c2 in a state close to the inclined surface 11c2. The top wall portion 77b surrounds the outlet 61c from above and the -X side. Therefore, 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. The installation method of the wiring cover 77 can be changed as appropriate. The wiring cover 77 may be attached to at least one of the corner bracket 36 and the vertical rod 61a, for example, or may be simply placed on the corner bracket 36. In addition, the wiring cover 77 may be, for example, only the side wall portion 77a or only the top wall portion 77b, as long as it is configured so that at least the outlet 61c and the upper end opening of the wiring passage groove 53 are not visible.

[0045] <Lighting unit 13> 1, 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 duct rail 81, a rail cover 82, a plug 83, and a lighting device 84.

[0046] FIG. 6 is a perspective view of the upper structure 22 seen from below with the lighting device 84 removed. 6, the duct rail 81 is U-shaped and opens downward, and extends in the X-direction. The duct rail 81 is fixed to the lower surface of the bridging bar 71.

[0047] The wiring 81a extending from the duct rail 81 is drawn into the wiring insertion space S2 through the through hole 71a formed in the bridging bar 71. Specifically, the through hole 71a penetrates the lower wall portion 71b of the bridging bar 71 in the vertical direction. The wiring 81a is routed through the inside of the bridging bar 71 (the wiring insertion space S2) toward the +X side through the through hole 71a. The wiring 81a that has passed through the inside of the bridging bar 71 is guided inside the horizontal rod 61b of the support 61 located on the +X side, and then 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 opening 61c, and then passes through the wiring cover 77. The wiring 81a is then guided into the wiring passing groove 53 through the communication groove 57 or the upper end opening of the wiring passing groove 53. The wiring 81a passes through the wiring passage groove 53, and then is drawn out into the space below the top plate 11 through the wiring drawing hole 54. The wiring 81a drawn out into the space below the top plate 11 is connected to an external power source (not shown) or the like.

[0048] FIG. 7 is a cross-sectional view taken along line VII-VII in FIG. As shown in Fig. 6 and Fig. 7, the rail cover 82 is formed in a cylindrical shape extending in the X direction. The rail cover 82 is attached to the bridging bar 71 so as to surround the periphery of the duct rail 81. In this embodiment, the duct rail 81 is attached to the bridging bar 71 by attaching half-split members having clearances to avoid the split bars 72, 73 to the bridging bar 71 from both sides in the Y direction. As shown in Fig. 6, an exposure opening 82b exposing the duct rail 81 is formed in a portion of the bottom wall 82a of the rail cover 82 that faces the duct rail 81 in the up-down direction. The plug 83 is attached to the duct rail 81 through the exposed opening 82b. That is, the plug 83 is electrically connected to an external power source or the like via the duct rail 81. 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.

[0049] 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 top plate 11 but reduced in size. As shown in Figs. 2 and 6, the lighting body 91 includes a plurality of lighting corners 91a and lighting side portions 91b connecting adjacent lighting corners 91a. The lighting corners 91a are formed in a circular arc shape protruding in a direction away from the center O2 of the lighting body 91 in a plan view. The lighting side portions 91b connect adjacent lighting corners 91a in a straight line.

[0050] As shown in FIG. 1, the spokes 92 connect the opposing lighting corners 91a to each other and are formed in an X-shape that intersects at the center O2 of the lighting body 91. The spokes 92 are suspended from a plug 83 via a wire 94. As shown in FIG. 2, the lighting body 91 is arranged such that the centers O1 and O2 of the lighting corners 91a and the tabletop corners 11a, and the lighting side portions 91b and the tabletop side portions 11b are aligned around the centers O1 and O2 in a plan view, and are concentrically arranged. That is, in a plan view, the corresponding lighting corners 91a and the tabletop corners 11a face each other in the X direction or the Y direction. Meanwhile, in a plan view, the corresponding lighting side portions 91b and the tabletop side portions 11b face each other in the front-rear direction or the left-right direction.

[0051] As shown in FIG. 6, the lighting body 91 includes a hood 95, a shade 96, and a light-emitting portion 97. The hood 95 constitutes the outer shape of the lighting body 91 in plan view. Specifically, the hood 95 is formed in a U-shape that opens downward in cross section, and is formed in a square frame shape. The hood 95 is made of a material that does not have optical transparency. A wiring 83a extending from the plug 83 is drawn into the lighting body 91. The shade 96 is made of a light-transmitting material and closes the lower end opening of the hood 95. The light-emitting unit 97 is housed inside the hood 95. The light-emitting unit 97 is composed of, for example, an LED or an organic EL. The light emitted by the light-emitting unit 97 passes through the shade 96 and is irradiated onto the upper surface of the tabletop 11.

[0052] Next, a method of using the display unit with tabletop 1 will be described. In the tabletop-equipped furniture 1 of this embodiment, 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.

[0053] 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.

[0054] In this way, the display fixture with a top plate 1 in this embodiment is configured to include a lower structure 21 that rises from the floor surface F, a top plate 11 supported from below by the lower structure 21, a top plate connecting portion 42 connected to the underside of the top plate 11, and a corner bracket (support member) 36 that extends from the top plate connecting portion 42 along the underside of the top plate 11 and has a connection portion 43 and a leg connecting portion 44 (extension portion) that protrudes from the outer peripheral edge of the top plate 11 in a plan view, and an upper structure 22 that is detachably attached to the leg connecting portion 44 and extends above the top plate 11, and has a lighting unit (item) 13 supported on a portion located above the top plate 11. According to this configuration, since the upper structure 22 is attached to the leg connectors 44 that protrude from the outer periphery of the tabletop 11, it is easier to secure a work area on the upper surface of the tabletop 11 compared to, for example, a case in which the upper structure 22 protrudes from the top surface of the tabletop 11. Furthermore, since the upper structure 22 is detachably attached to the leg connectors 44, it is easier to carry in and out parts compared to a configuration in which the upper structure 22 and the corner brackets 36 are integrally formed. This improves the work efficiency during assembly. Also, since the upper structure 22 is detachably attached to the leg connectors 44, the form of the tabletop-equipped furniture 1 can be flexibly changed depending on whether the upper structure 22 is required or not.

[0055] In the present embodiment of the tabletop-equipped fixture 1, the upper structure 22 is configured to include a vertical rod (standing portion) 61a, a horizontal rod 61b extending from the upper end of the vertical rod 61a in the X direction or Y direction (intersecting direction), and a connecting bar 62 (item support portion). According to this configuration, since the horizontal rod 61b and the connecting bar 62 extend in the X direction or the Y direction, articles such as the lighting device 84 can be placed at any position in the intersecting direction.

[0056] In the tabletop-equipped fixture 1 of this embodiment, the corner brackets 36 are configured to be provided integrally with the lower structure 21. According to this configuration, since the corner brackets 36 are provided integrally with the lower structure 21, the configuration can be simplified and costs can be reduced compared to a configuration in which the corner brackets 36 and the lower structure 21 are provided separately. Also, by making the corner brackets 36 a part of the lower structure 21, the strength of the lower structure 21 as a whole to support the upper structure 22 can be ensured. Therefore, the upper structure 22 can be stably supported with a simpler configuration compared to a case in which the strength to support the upper structure 22 is ensured by the corner brackets 36 alone.

[0057] In the present embodiment of the tabletop-equipped fixture 1, multiple corner brackets 36 are provided at intervals along the outer periphery of the tabletop 11, and the upper structure 22 includes pillars 61 each attached to the leg connecting portions 44 of the multiple corner brackets 36, and the pillars 61 attached to each corner bracket 36 are connected to each other above the tabletop 11. This configuration makes it easier to ensure the strength of the upper structure 22, and allows for greater freedom in terms of the size and weight of the items supported by the upper structure 22. Moreover, the sides and top of the tabletop 11 are surrounded by the upper structure 22, providing a sense of enclosure to users of the tabletop-equipped furniture unit 1. This allows both individual and group work to be done efficiently.

[0058] In the present embodiment of the tabletop-equipped display unit 1, a pillar accommodating groove (recess) 55 that is open upward and to the sides is formed in the leg connecting portion 44, and the lower end of the pillar 61 (vertical rod 61a) is configured to be fitted into the pillar accommodating groove 55. According to this configuration, the ease of assembly between the leg connecting portion 44 and the support column 61 can be improved.

[0059] In the tabletop-equipped fixture 1 of this embodiment, the upper structure 22 is configured to have a wiring insertion space S2 formed therein through which the wiring 81a can pass. According to this configuration, even when electrical equipment such as the lighting unit 13 is provided on the upper structure 22, the wiring 81a can be routed downward without being exposed to the outside of the upper structure 22. This can improve the appearance of the furniture with a top panel 1.

[0060] (Other variations) Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Addition, omission, substitution, and other modifications of the configuration are possible without departing from the spirit of the present invention. The present invention is not limited by the above description, but is limited only by the scope of the attached claims. In the above embodiment, a table has been used as an example of the tabletop-equipped fixture 1, but the present invention is not limited to this configuration. The tabletop-equipped fixture according to the present invention can be used in various fixtures having a tabletop, such as shelves and cart devices. In the above embodiment, the top plate 11 is formed in a square shape in plan view, but the present invention is not limited to this configuration.

[0061] In the above embodiment, a configuration has been described in which the tabletop-equipped fixture 1 includes an upper structure 22, but the present invention is not limited to this configuration. As shown in FIG. 9, the tabletop-equipped fixture 1 may be configured not to include an upper structure 22. In this case, a common lower structure 21 can be used regardless of whether the upper structure 22 is included or not. If the upper structure 22 is not attached, a cap 100 or the like can be provided inside the leg connecting portion 44 or the wire passing groove 53. This can prevent the leg connecting portion 44 or the wire passing groove 53 from being exposed to the outside, improving the appearance.

[0062] In the above embodiment, the lighting unit 13 has been described as an example of an article supported by the upper structure 22, but the present invention is not limited to this configuration. The article supported by the upper structure 22 can be appropriately selected from a signboard 110 as shown in Fig. 10, a monitor, a flag, a plant, a partition, a hook, a magnet, and the like. In the above embodiment, the configuration has been described in which an article is supported by the portion (horizontal rod 61b or connecting bar 62) of the upper structure 22 that intersects in the vertical direction above the top board 11, but the present invention is not limited to this configuration. The article may be supported by the vertical rod 61a.

[0063] In the above embodiment, the upper structure 22 is configured by a combination of rod-shaped members, but the present invention is not limited to this configuration. At least a part of the upper structure 22 may be in the form of a panel. For example, the upper structure may cover the top of the tabletop 11 in the form of a hood. In the above embodiment, the configuration has been described in which the support columns 61 of the upper structure 22 are provided to correspond to each tabletop corner portion 11a of the tabletop 11, but the configuration is not limited to this. The support columns 61 may be provided to correspond to any one of the tabletop corner portions 11a, or may be provided to the side of the tabletop side portion 11b.

[0064] In the above-described embodiment, a configuration has been described in which the support members that support the upper structure 22 are provided integrally with the lower structure 21 as corner brackets 36, but the present invention is not limited to this configuration. As shown in Fig. 11, the support members 130 include a connecting portion 130a fixed to the underside of the tabletop 11, and an extending portion 130b that extends from the connecting portion 130a along the underside of the tabletop 11 and protrudes from the outer periphery of the tabletop 11. A support column 61 that constitutes the upper structure 22 is attached to the extending portion 130b. Furthermore, when the lower structure 21 and the support members 130 are provided separately, the number of support legs 32 and the like is not limited by the number of columns 61. In this case, the support legs may be single-column legs or the like.

[0065] In the above embodiment, the configuration in which the multiple support columns 61 are connected to each other above the top board 11 has been described, but the present invention is not limited to this configuration. The upper ends of the support columns 61 may be free ends, for example. In the above embodiment, the horizontal rod 61b extends toward the center O1 of the tabletop 11 in a plan view, but the present invention is not limited to this configuration. The horizontal rod 61b may extend along the outer periphery of the tabletop 11 in a plan view, or may extend in a direction away from the center O1 of the tabletop 11.

[0066] In the above embodiment, the configuration in which the support pillar 61 (vertical rod 61a) is fitted into the support pillar receiving groove 55 of the leg connecting portion 44 has been described, but the present invention is not limited to this configuration. The support pillar receiving groove 55 may open only upward so that the support pillar 61 can be inserted from above. In addition, the method of attaching the support pillar 61 to the extension portion can be changed as appropriate, for example, by attaching the support pillar 61 to the extension portion by screwing the support pillar 61 into the extension portion, or by fixing the support pillar 61 to the extension portion by a separate screw or the like while the support pillar 61 is abutted against the extension portion in the vertical direction. In addition, the support member may be inserted into the support pillar 61.
