Description

[Technical field]

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

[0002] A tabletop-equipped fixture such as a table or desk has a tabletop and a support structure that supports the tabletop from below. Some such tabletop-equipped fixtures have an overhanging portion where the end of the tabletop protrudes laterally from the support structure. For example, Patent Document 1 discloses a table whose tabletop is supported by four legs. The tabletop of this table has an overhanging portion that is triangular in plan view and protrudes outward in the width direction from the legs. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Jitsuhei 7-50972 Publication Summary of the Invention [Problem to be solved by the invention]

[0004] However, in a display unit with a tabletop that has an overhanging top, such as that disclosed in Patent Document 1, when a load from an item or a user is applied to the overhanging part on one side of the width of the tabletop, the supporting structure on the other side of the width (the opposite side) may lift up from the floor, potentially compromising the stability of the display unit when installed. The present invention aims to provide a display unit with a tabletop that can increase installation stability even when a load acts on the overhanging portion. [Means for solving the problem]

[0005] In order to solve the above problems, the present invention employs the following aspects. (1) A display unit with a tabletop according to one embodiment of the present invention comprises a support structure having a pair of leg members spaced apart in the width direction, and a tabletop supported from below by the support structure, wherein the tabletop comprises a main body portion located between the pair of leg members in the width direction, and an overhang portion extending outward in the width direction from the main body portion with respect to at least one of the pair of leg members, and the main body portion has an average mass per unit area when viewed from the top and bottom direction that is greater than that of the overhang portion. According to this aspect, the average mass per unit area of ​​the main body of the tabletop when viewed from above and below is greater than that of the overhanging portion, so when a load acts vertically downward on the overhanging portion on one side in the width direction, the mass of the main body prevents the leg member on the other side in the width direction from being lifted up. As a result, the installation stability of the tabletop-equipped fixture can be improved even when a load acts on the overhanging portion. In this case, by prioritizing the weight of the main body, the tabletop as a whole can be made lighter and thinner than when the weight of the entire tabletop is secured to improve installation stability.

[0006] (2) In the display unit with a tabletop according to the above aspect (1), it is preferable that the main body portion is provided with a weight that applies a load vertically downward. According to this aspect, by providing a weight to the main body, the average mass per unit area of ​​the main body of the tabletop when viewed from the top can be easily made larger than that of the overhanging part. Also, by adjusting the mass of the weight according to the widthwise outward projection dimension of the overhanging part, the installation stability of the tabletop-equipped fixture can be appropriately improved.

[0007] (3) A display unit with a tabletop according to one embodiment of the present invention comprises a support structure having a pair of leg members spaced apart in the width direction, and a tabletop supported from below by the support structure, wherein the tabletop comprises a main body portion located between the pair of leg members in the width direction, an overhang portion extending outward in the width direction from the main body portion for at least one of the pair of leg members, and a weight at least a portion of which is located on the side opposite the side on which the overhang portion is located, sandwiching the leg member on which the overhang portion is located in the width direction, and which applies a vertically downward load to the main body portion. According to this aspect, by providing at least a part of the weight on the opposite side of the leg member having the overhang portion in the width direction between the leg member having the overhang portion and the weight, when a load acts vertically downward on the overhang portion, the opposite side of the leg member having the overhang portion is prevented from being lifted up due to the weight of the weight. As a result, the installation stability of the tabletop-equipped furniture can be improved even when a load acts on the overhang portion.

[0008] (4) In the display fixture with a top relating to the above-mentioned (2) or (3), the top has a hollow structure comprising a lower plate extending along a plane intersecting in the vertical direction, an upper plate spaced above the lower plate and extending along a plane intersecting in the vertical direction, and a frame material interposed between the outer peripheral edge of the lower plate and the outer peripheral edge of the upper plate and connecting the lower plate and the upper plate, and it is preferable that the weight is contained in the internal space of the main body surrounded by the lower plate, the upper plate, and the frame material. According to this aspect, since the weight is accommodated in the internal space of the main body, the weight is not exposed to the outside of the main body, and thus it is possible to prevent damage to the appearance.

[0009] (5) In the display fixture with a tabletop relating to the above-mentioned (4) aspect, it is preferable that the weight further comprises a positioning portion that is adhered to the upper surface of the lower plate and that positions the weight in a plane along the upper surface of the lower plate. According to this aspect, the positioning portion enables the weight to be positioned in a plane along the upper surface of the lower plate relative to the lower plate, improving workability when adhering the weight to the upper surface of the lower plate.

[0010] (6) In the fixture with a tabletop relating to the above-mentioned (4) or (5) aspect, it is preferable that the tabletop further includes a reinforcing beam fixed to at least one of the underside of the upper plate and the upper side of the lower plate and extending in a direction intersecting the vertical direction, and that the weight is provided separately from the reinforcing beam. According to this aspect, by providing the weight separately from the reinforcing beam, the average mass per unit area of ​​the main body of the tabletop, when viewed from the top and bottom, can be made greater than that of the overhanging portion, without affecting the design of the reinforcing beam.

[0011] (7) In the display fixture with a tabletop relating to any one of the above aspects (2) to (6), it is preferable that the weight extends in the width direction and is arranged so as to straddle the pair of leg members when viewed from the top-bottom direction. According to this aspect, since the weight extends in the width direction, the weight contributes to improving the strength of the tabletop in the width direction. Furthermore, since the weight is provided so as to straddle the pair of leg members when viewed from above, the strength of the tabletop supported from below by the pair of leg members is particularly increased.

[0012] (8) In the display fixture with a countertop according to any one of the above aspects (2) to (7), it is preferable that the weight is made of metal and formed into a solid block shape. According to this aspect, by forming the weight from metal in the shape of a solid block, it is possible to prevent the weight from becoming too large while allowing the mass of the weight to act effectively on the main body portion.

[0013] (9) In a display unit with a countertop relating to any one of the above aspects (2) to (8), it is preferable that the overhanging portions are provided on both widthwise sides of the main body, the countertop is formed symmetrically in the widthwise direction with respect to the center in the widthwise direction when viewed from the top-bottom direction, and the weight is provided in an area including the center in the widthwise direction. According to the present aspect, when the overhang portions are provided on both sides of the main body portion in the width direction, by providing the weight in an area including the center portion in the width direction, regardless of whether a load acts on the overhang portion on either side in the width direction, the mass of the main body portion can effectively prevent the leg member on the opposite side to the side on which the load acts in the width direction from being lifted up.

[0014] (10) In a display unit with a tabletop according to any one of the above aspects (2) to (9), it is preferable that, when viewed from the top, the tabletop is formed asymmetrically in the front-to-back direction relative to the center of the tabletop in the front-to-back direction, and the weight is provided on the side of the tabletop which has a smaller area when viewed from the top-to-bottom direction relative to the center of the front-to-back direction. According to this aspect, when the tabletop is asymmetrically formed in the front-to-rear direction with respect to the center of the tabletop in the front-to-rear direction when viewed from the top-to-bottom direction, the side of the tabletop with a larger area in the front-to-rear direction with respect to the center of the tabletop in the front-to-rear direction has a larger mass than the side of the tabletop with a smaller area in the front-to-rear direction with respect to the center of the tabletop in the front-to-rear direction. In contrast, according to this aspect, the weight balance of the tabletop in the front-to-rear direction can be improved because the weight is provided on the side of the tabletop with a smaller area in the front-to-rear direction with respect to the center of the tabletop in the front-to-rear direction.

[0015] (11) In a fixture with a tabletop relating to any one of the above aspects (2) to (10), it is preferable that the support structure has a support axis that supports the tabletop so that the tabletop can rotate around an axis extending in the width direction, and that the weight is provided in the front-to-back direction either in front of the support axis, in a position that overlaps with the support axis when viewed from the top-to-bottom direction, or in a position behind the support axis. According to this aspect, when the tabletop is rotatable around an axis extending in the width direction by a support shaft provided on the support structure, the weight can be arranged at an appropriate position in the front-rear direction to adjust the effect on the rotation of the tabletop. For example, when the weight is arranged in a position forward of the support shaft, the tabletop can be prevented from rotating from a horizontal state. When the weight is arranged in a position rearward of the support shaft, the tabletop can be easily raised from a horizontal state. When the weight is arranged in a position overlapping with the support shaft when viewed from the top-bottom direction, the effect of the weight on the rotation of the tabletop can be reduced.

[0016] (12) In the display unit with a tabletop according to any one of the above aspects (1) to (11), it is preferable that the main body portion is heavier than the overhang portion. According to this aspect, by making the weight of the main body greater than that of the overhanging portion, when a load acts on the overhanging portion on one side in the width direction, the mass of the main body is prevented from lifting the leg member on the other side in the width direction. Effect of the Invention

[0017] According to one aspect of the present invention, installation stability can be improved even when a load acts on the overhang portion. [Brief description of the drawings]

[0019] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to this embodiment.

[0020] (First embodiment) Fig. 1 is a perspective view showing the appearance of a tabletop-equipped fixture 1 according to a first embodiment of the present invention. Fig. 2 is a side view of the tabletop-equipped fixture 1 as viewed from the width direction Dw. As shown in Figs. 1 and 2, the tabletop-equipped fixture 1 is placed on a floor surface F. The tabletop-equipped fixture 1 includes a tabletop 40A and a support structure 11. The tabletop-equipped fixture 1 in this embodiment is a so-called flap type, and the tabletop 40A is rotatable. Note that the tabletop-equipped fixture 1 may be configured such that the tabletop 40A cannot be rotated.

[0021] The support structure 11 supports the tabletop 40A from below. The support structure 11 mainly includes a pair of leg members 12 and a tabletop rotation mechanism 3 (see FIG. 2). In the following description, the direction perpendicular to the floor surface F is referred to as the up-down direction Dv, the direction intersecting the up-down direction Dv and separating the pair of leg members 12 is referred to as the width direction Dw, and the direction intersecting the up-down direction Dv and the width direction Dw is referred to as the front-rear direction Da. In addition, in the front-rear direction Da, one side is referred to as the front, and the other is referred to as the rear. Note that the front and rear in the front-rear direction Da do not limit the usage mode of the tabletop-equipped fixture 1, that is, the side on which the user is positioned relative to the tabletop-equipped fixture 1. In this embodiment, in the front-rear direction Da, the side on which the valance 21 described below is provided is referred to as the rear, and the opposite side is referred to as the front.

[0022] The pair of leg members 12 are provided with a gap therebetween in the width direction Dw. The pair of leg members 12 have a configuration symmetrical to each other. The pair of leg members 12 are joined together via a cross frame 16 extending in the width direction Dw. Each leg member 12 includes a leg pillar 13 and a support leg 14.

[0023] The leg pillars 13 extend in the vertical direction Dv and support the tabletop 40A from below. The leg pillars 13 extend from above to below, gradually inclining backward. The support leg 14 extends outward in the width direction Dw from below the center of the leg pillar 13 in the up-down direction Dv, then curves forward and extends diagonally downward toward the front. The lower end of each leg 13 and the rear end of each support leg 14 are grounding parts that come into contact with the floor surface F. In this embodiment, the lower end of each leg 13 and the rear end of each support leg 14 are provided with casters 15 that enable the tabletop-equipped furniture 1 to be moved on the floor surface F.

[0024] 2, the tabletop rotating mechanism 3 is provided at the upper end of the leg pillar 13. The tabletop rotating mechanism 3 supports the tabletop 40A at the upper end of the leg pillar 13 so that the tabletop 40A can rotate about a central axis C of a support shaft 4 extending in the width direction Dw. The tabletop rotating mechanism 3 includes a tabletop side bracket 3a, a leg pillar side bracket 3b, and the support shaft 4.

[0025] The top plate side bracket 3a is joined to the lower surface 40b of the top plate 40A by bolts (not shown) etc. The pillar side bracket 3b is joined to the upper end of the pillar 13 by welding or the like. The support shaft 4 is disposed below the tabletop 40A. The support shaft 4 is disposed rearward of the center portion Ca of the tabletop 40A in the front-rear direction Da. The support shaft 4 extends in the width direction Dw. The support shaft 4 connects the tabletop side bracket 3a and the leg pillar side bracket 3b to be rotatable relative to each other around the central axis C of the support shaft 4.

[0026] FIG. 3 is a diagram showing a state in which the top plate 40A of the tabletop-equipped furniture 1 shown in FIG. 2 is flipped up. The tabletop rotation mechanism 3 can rotate between a use position P1, where the work surface 40t of the tabletop 40A is aligned with a horizontal plane, and a flip-up position P2, where the front edge 40f of the tabletop 40A is flipped up relative to the rear edge 40r, as shown in Fig. 3. The tabletop rotation mechanism 3 is equipped with a locking mechanism (not shown) that can restrict the relative rotation of the tabletop side bracket 3a and the leg column side bracket 3b when the tabletop 40A is in either the use position P1 or the flip-up position P2. Reference numeral 3c in the figure denotes an unlocking lever for unlocking the locking mechanism.

[0027] 2, the tabletop-equipped fixture 1 in this embodiment includes a back panel 21. Note that the back panel 21 is not an essential component, and the fixture may be configured without the back panel 21. The front panel 21 is provided below the top panel 40A. The front panel 21 is provided behind the leg posts 13. The front panel 21 extends along a plane intersecting the front-rear direction Da. The front panel 21 is connected to the support structure 11 via a lower link mechanism 25 and an upper link mechanism 26, which are provided on both sides in the width direction Dw.

[0028] The lower link mechanism 25 includes a lower bracket 251 , a link arm 252 , a first rotating shaft 253 , and a second rotating shaft 254 . The lower bracket 251 is fixed to the front surface 21b of the lower end of the apron 21. One end of the link arm 252 is connected to the lower bracket 251 via a first rotating shaft 253, and the other end is connected to the leg column 13 via a second rotating shaft 254. The first rotating shaft 253 connects the lower bracket 251 and the link arm 252 to be relatively rotatable about an axis extending in the width direction Dw. The second rotating shaft 254 connects the other end of the link arm 252 to the leg column 13 to be relatively rotatable about an axis extending in the width direction Dw.

[0029] The upper link mechanism 26 includes a front panel side arm 261 , a top panel side arm 262 , and an upper rotating shaft 263 . The front panel side arm 261 is fixed to the front surface 21b of the upper end of the front panel 21. The front panel side arm 261 extends obliquely upward toward the front. The top panel side arm 262 is fixed to the lower surface of the top panel 40A behind the support shaft 4. The top panel side arm 262 may be fixed to the top panel side bracket 3a. The top panel side arm 262 is L-shaped when viewed from the width direction Dw, and integrally includes a rearward extending portion 262a extending rearward and a downward extending portion 262b extending downward from the rear end of the rearward extending portion 262a. The upper rotating shaft 263 connects the tip of the front panel side arm 261 and the tip of the top panel side arm 262 to be rotatable around an axis extending in the width direction Dw.

[0030] The lower link mechanism 25 and the upper link mechanism 26 enable the skirting board 21 to rotate between a hanging position P3 (see Figure 2) and a storage position P4 (see Figure 3) in conjunction with the rotation of the top board 40A between the use position P1 and the flip-up position P2.

[0031] As shown in FIG. 3, when the top panel 40A is in the use position P1, the top panel 21 is disposed in a hanging position P3 so as to extend in the up-down direction Dv behind the top panel 40A when viewed in the width direction Dw. When the tabletop 40A is rotated around the support shaft 4 so that the front edge 40f is flipped upward from the use position P1 towards the flip-up position P2, the tabletop side arm 262 is displaced together with the tabletop 40A. Then, the tip of the top panel side arm 261 connected to the tip of the tabletop side arm 262 is displaced forward and downward. As a result, the upper part of the top panel 21 is displaced forward and downward and approaches the leg pillar 13. At this time, the lower part of the top panel 21 is also pushed downward, and the link arm 252 is rotated around the second pivot shaft 254 so that the first pivot shaft 253 is displaced downward. As a result, the lower part of the top panel 21 is pulled forward and downward and approaches the leg pillar 13. In this way, when the top panel 40A is in the raised position P2, the front panel 21 is disposed in the stored position P4 so as to be closer to the leg pillar 13 than the hanging position P3 when viewed from the width direction Dw.

[0032] Fig. 4 is a perspective view showing a state where the top plate 40A of the above-mentioned tabletop-equipped fixture 1 has the upper plate 42 removed. Fig. 5 is a plan view showing a state where the top plate 40A has the upper plate 42 removed. As shown in Figs. 1, 4, and 5, the top plate 40A is, for example, hexagonal when viewed from the up-down direction Dv, and is formed with a uniform thickness over the entire top plate 40A. The top plate 40A has a front edge portion 40f, a rear edge portion 40r, a pair of front side edges 40p, and a pair of rear side edges 40q. The front edge portion 40f extends in the width direction Dw at the front of the top plate 40A. The rear edge portion 40r extends in the width direction Dw at the rear of the top plate 40A. In this embodiment, the front edge portion 40f is formed longer in the width direction Dw than the rear edge portion 40r.

[0033] The pair of front side edges 40p extend rearward from the outer ends of the front edge 40f in the width direction Dw at both sides of the table top 40A in the width direction Dw, inclining outward in the width direction Dw. The pair of rear side edges 40q extend rearward from the pair of rear side edges 40q at both sides of the table top 40A in the width direction Dw, inclining inward in the width direction Dw. Here, as shown in FIG. 5, in the tabletop 40A of this embodiment, on both sides in the width direction Dw, the apex 40z formed by the front side edge 40p and the rear side edge 40q is positioned forward of the center Ca of the tabletop in the front-to-rear direction Da.

[0034] The top plate 40A has a main body portion 40T and an overhang portion 40S. The main body portion 40T is located between a pair of leg members 12 in the width direction Dw. In this embodiment, the overhang portions 40S are provided on both sides of the main body portion 40T in the width direction Dw. The overhang portions 40S are provided to protrude from the main body portion 40T to the pair of leg members 12 in the width direction Dw. The overhang portions 40S refer to a portion located outside in the width direction Dw with respect to the portion of the leg member 12 that is the outermost in the width direction Dw. In this embodiment, the overhang portions 40S are portions that are outside in the width direction Dw of the lower ends of the leg columns 13 and the rear ends of the support legs 14, which are the ground contact portions. In this embodiment, the tabletop 40A having the overhang portions 40S on both sides in the width direction Dw is formed to be line-symmetrical in the width direction Dw with respect to the center portion Ca in the width direction Dw when viewed from the up-down direction Dv. Also, the tabletop 40A is formed to be asymmetrical in the front-rear direction Da with respect to the center portion Ca in the front-rear direction Da of the tabletop 40A when viewed from the up-down direction Dv.

[0035] FIG. 6 is a cross-sectional view of the main body portion 40T of the top plate 40A as viewed in the width direction Dw. As shown in FIGS. 4 to 6, the top plate 40A includes a lower plate 41, an upper plate 42 (see FIG. 6), a frame member 43, a reinforcing beam 44, a cushioning material 47, and a weight 50A.

[0036] As shown in FIG. 5 and FIG. 6, the lower plate 41 is provided at the lower part of the top plate 40A. The lower plate 41 extends along a plane intersecting with the up-down direction Dv. The lower plate 41 is made of, for example, a metal plate. A front rib 41a extending in the width direction Dw is integrally formed at the front end of the lower plate 41. As shown in FIG. 6, the front rib 41a has a rising wall portion 41a1 rising upward from the lower plate 41 and a rear extension portion 41a2 extending rearward from the upper end of the rising wall portion 41a1. In addition, a rear rib 41b extending in the width direction Dw is integrally formed at the rear end of the lower plate 41. The rear rib 41b has a rising wall portion 41b1 rising upward from the lower plate 41 and a front extension portion 41b2 extending forward from the upper end of the rising wall portion 41b1.

[0037] The upper plate 42 is provided above and spaced apart from the lower plate 41. The upper plate 42 extends along a plane intersecting with the vertical direction Dv. The upper plate 42 is formed by, for example, stacking an upper plate base material and a decorative plate that is provided on the upper plate base material and forms the work surface 40t in the vertical direction Dv.

[0038] The frame material 43 is interposed between the outer peripheral edge of the lower plate 41 and the outer peripheral edge of the upper plate 42, and connects the lower plate 41 and the upper plate 42. As shown in Figs. 4 and 5, the frame material 43 is provided on both ends of the lower plate 41 (and the upper plate 42) in the width direction Dw. When viewed from the up-down direction Dv, each frame material 43 is bent and extends continuously along the end of the front edge portion 40f in the width direction Dw, the front side edge portion 40p, the rear side edge portion 40q, and the end of the rear edge portion 40r in the width direction Dw. In this case, each frame material 43 is formed in a ring shape extending along the outer periphery of the top plate 40A together with the front rib 41a and the rear rib 41b. In addition, an edge material 49 (see Fig. 6) constituting the outer periphery of the top plate 40A is attached so as to surround the front rib 41a, the rear rib 41b, and the frame materials 43 on both sides in the width direction Dw. Each frame material 43 is made of, for example, MDF (Medium Density Fiberboard) material, and is joined to the lower plate 41 and the upper plate 42 by adhesive or the like.

[0039] The top plate 40A has a hollow structure surrounded by a lower plate 41, an upper plate 42, a front rib 41a, a rear rib 41b, and frame members 43 on both sides in the width direction Dw, and has an internal space S.

[0040] As shown in Figs. 4 to 6, the reinforcement beam 44 is provided in the internal space S of the top plate 40A. In this embodiment, the reinforcement beam 44 has a first reinforcement beam 44A and a second reinforcement beam 44B. The first reinforcement beam 44A is provided inside the frame members 43 on both sides in the width direction Dw, extending in the width direction Dw and connecting the vicinity of the tops 40z. In other words, both ends of the first reinforcement beam 44A in the width direction Dw are located outside the leg members 12 when viewed from the up-down direction Dv. The second reinforcement beam 44B is provided rearwardly and spaced apart from the first reinforcement beam 44A. The second reinforcement beam 44B extends in the width direction Dw. Specifically, the second reinforcement beam 44B is provided so as to bridge between the leg members 12 when viewed from the up-down direction Dv. Therefore, as shown in FIG. 5, each of the first reinforcement beam 44A and the second reinforcement beam 44B is provided so as to overlap with the tabletop side arm 262 when viewed from the up-down direction Dv. As a result, the load from the vertically upward direction supported by the first reinforcement beam 44A and the second reinforcement beam 44B is transmitted to the pair of leg members 12 (pillars 13) via the tabletop rotation mechanism 3.

[0041] As shown in Fig. 6, each of the first reinforcement beam 44A and the second reinforcement beam 44B is made of a so-called C-shaped channel material and integrally includes a base 44c, a pair of walls 44d, and a pair of extensions 44e. The base 44c extends in a strip shape in the width direction Dw along the upper surface of the lower plate 41. Each of the pair of walls 44d rises upward from both ends of the base 44c in the front-rear direction Da. Each of the pair of extensions 44e extends from the upper end of the wall 44d toward the wall 44d side that faces it in the front-rear direction Da. The base portions 44c of the first reinforcement beam 44A and the second reinforcement beam 44B are joined to the upper surface of the upper plate 42 by welding, screws, adhesive, etc. The first reinforcement beam 44A and the second reinforcement beam 44B add rigidity to the lower plate 41 and the upper plate 42 against bending moments caused by loads from above.

[0042] The front rib 44a, the rear rib 41b, the frame members 43 on both sides in the width direction Dw, and the first and second reinforcing beams 44A and 44B have the same height. The front rib 44a, the rear rib 41b, the frame members 43 on both sides in the width direction Dw, and the first and second reinforcing beams 44A and 44B are each joined to the lower surface of the upper plate 42 by an adhesive or the like.

[0043] As shown in Figs. 4 to 6, the top plate 40A further includes a cushioning material 47 between the lower plate 41 and the upper plate 42. The cushioning material 47 is provided in the internal space S between the front rib 44a and the first reinforcement beam 44A and between the first reinforcement beam 44A and the second reinforcement beam 44B. The cushioning material 47 is made of, for example, polystyrene foam. The cushioning material 47 is in contact with the upper surface of the lower plate 41 and the lower surface of the upper plate 42 for vibration and sound insulation, etc.

[0044] The weight 50A is accommodated in the internal space S of the main body 40T of the top plate 40A. The weight 50A applies a vertically downward load to the main body 40T of the top plate 40A. The weight 50A is made of metal, such as SPHC (hot-rolled mild steel plate), and is formed in a solid block shape. The weight 50A is thicker than the lower plate 41 and the upper plate 42. The weight 50A is disposed between the pair of leg members 12 over its entire width direction Dw. In the illustrated example, the weight 50A is disposed inside the pair of leg members 12 in the width direction Dw when viewed from the up-down direction Dv. 5, the weight 50A is provided on the opposite side of the leg member 12R on the side on which the overhang portion 40S1 is provided on one side in the width direction Dw of the leg member 12. The weight 50A is provided on the opposite side of the leg member 12L on the side on which the overhang portion 40S2 is provided on the other side in the width direction Dw of the leg member 12 from the side on which the overhang portion 40S2 is provided.

[0045] The weight 50A is, for example, bonded to the upper surface of the lower plate 41. That is, the weight 50A is in contact with at least the upper surface of the lower plate 41. However, the weight 50A may be in contact with both the upper surface of the lower plate 41 and the lower surface of the upper plate 42, or may be in contact with only the lower surface of the upper plate 42. Furthermore, the weight 50A may be fixed to the lower plate 41 by screws or the like.

[0046] By providing such weights 50A, the average value of the mass per unit area of ​​the main body 40T when viewed from the up-down direction Dv is greater than that of the overhanging portions 40S. Also, the weight of the entire main body 40T including the weights 50A is greater than the weight of one of the overhanging portions 40S. In this embodiment, the weight of the entire main body 40T is greater than the total weight of each of the overhanging portions 40S.

[0047] As shown in FIG. 5, the weight 50A is provided in an area including the center part Ca in the width direction Dw of the tabletop 40A. The weight 50A is provided on the rear side of the tabletop 40A, which has a smaller area when viewed from the up-down direction Dv, with respect to the center part Ca in the front-back direction Da. Furthermore, in this embodiment, the weight 50A is provided at a position in the front-back direction Da where the weight 50A overlaps with the support shaft 4 when viewed from the up-down direction Dv. As shown in FIG. 5 and FIG. 6, the weight 50A is provided behind the center of gravity G1 in the front-back direction Da of the tabletop 40A alone, excluding the weight 50A. When the weight of the tabletop 40A itself is about 18 kg, such a weight 50A is preferably about 4 to 8 kg in mass. In this embodiment, the weight 50A has a mass of, for example, 6 kg. By providing such a weight 50A, the center of gravity G2 of the tabletop 40A including the weight 50A is shifted rearward from the center of gravity G1. In this embodiment, the center of gravity G2 of the tabletop 40A and the weight 50A combined is located forward with respect to the support shaft 4.

[0048] In this manner, in this embodiment, the main body portion 40T of the tabletop 40A is configured so that the average value of the mass per unit area when viewed in the up-down direction Dv is greater than that of the overhang portion 40S. According to this configuration, when a vertically downward load acts on one of the overhanging portions 40S in the width direction Dw, the mass of the main body portion 40T prevents the leg member 12 on the other side in the width direction Dw from being lifted. As a result, even when a vertically downward load acts on the overhanging portion 40S, the installation stability of the tabletop-equipped fixture 1 can be improved. In this case, by giving priority to the weight of the main body portion 40T, the tabletop 40A as a whole can be made lighter and thinner than when the weight of the entire tabletop 40A is secured to improve installation stability.

[0049] In this embodiment, a weight 50A is provided on the main body 40T. With this configuration, the average mass per unit area of ​​the main body 40T of the tabletop 40A when viewed in the vertical direction Dv can be easily made larger than that of the overhanging portion 40S. Also, by adjusting the mass of the weight 50A according to the outward projection dimension of the overhanging portion 40S in the width direction Dw, the installation stability of the tabletop-equipped fixture 1 can be appropriately improved.

[0050] In this embodiment, the pair of leg members 12 are configured so that the weight 50A is provided on the opposite side to the side on which the overhang portion 40S is provided, sandwiching the leg member 12 on which the overhang portion 40S is provided in the width direction Dw. With this configuration, when a vertically downward load acts on the overhang portion 40S, the mass of the weight 50A prevents the side opposite the leg member 12 on which the overhang portion 40S is provided from lifting up in the width direction Dw. As a result, even when a load acts on the overhang portion 40S, the installation stability of the tabletop-equipped fixture 1 can be improved.

[0051] In this embodiment, the weight 50A is configured to be housed in the internal space S of the main body portion 40T. According to this configuration, the weight 50A is not exposed to the outside of the main body 40T, and thus it is possible to prevent the appearance from being spoiled.

[0052] In this embodiment, the weight 50A is provided separately from the reinforcing beam 44. According to this configuration, the average mass per unit area of ​​the main body 40T of the tabletop 40A when viewed in the vertical direction Dv can be made greater than that of the overhang portion 40S without affecting the design of the reinforcement beam 44. In particular, since at least a portion of the reinforcement beam 44 (first reinforcement beam 44A) protrudes outward relative to the pair of leg members 12, the overall tabletop 40A can be made lighter and thinner while also ensuring the rigidity of the entire tabletop 40A, including the overhang portion 40S.

[0053] In this embodiment, the weight 50A is made of metal and formed into a solid block shape. According to this configuration, the mass of the weight 50A can be effectively applied to the main body portion 40T while preventing the weight 50A from becoming large.

[0054] In this embodiment, the overhang portions 40S are provided on both sides of the body portion 40T in the width direction Dw, and the weight 50A is provided in a region including the center portion Ca in the width direction Dw. According to this configuration, regardless of whether a load acts on the overhang portion 40S on either side in the width direction Dw, the mass of the main body portion 40T can effectively prevent the leg member 12 on the opposite side to the side on which the load acts in the width direction Dw from being lifted up.

[0055] In this embodiment, the weight 50A is provided on the side of the tabletop 40A that has a smaller area as viewed from the vertical direction Dv with respect to the central portion Ca in the front-rear direction Da. When viewed from the vertical direction Dv, the tabletop 40A is formed asymmetrically in the front-rear direction Da with respect to the central portion Ca of the tabletop 40A in the front-rear direction Da. Therefore, the tabletop 40A alone has a larger mass on the side of the tabletop 40A that has a larger area as viewed from the vertical direction Dv with respect to the central portion Ca of the tabletop 40A in the front-rear direction Da than on the side of the tabletop 40A that has a smaller area as viewed from the vertical direction Dv. In response to this, the weight 50A is provided on the side of the tabletop 40A that has a smaller area as viewed from the vertical direction Dv with respect to the central portion Ca of the tabletop 40A in the front-rear direction Da, thereby improving the weight balance of the tabletop 40A in the front-rear direction Da.

[0056] In this embodiment, the top plate 40A is rotatable around an axis extending in the width direction Dw by a support shaft 4 provided on the support structure 11, and the weight 50A is configured to be positioned so as to overlap with the support shaft 4 when viewed from the vertical direction Dv. According to this configuration, the effect of the weight 50A on the rotation of the tabletop 40A can be suppressed, and the tabletop 40A can be rotated with a light force.

[0057] In this embodiment, the weight of the main body portion 40T is made greater than the weight of the overhang portion 40S. According to this configuration, when a load acts on the overhang portion 40S on one side in the width direction Dw, the leg member 12 on the other side in the width direction Dw is prevented from being lifted up due to the mass of the main body portion 40T.

[0058] 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.

[0059] (First Modification of the First Embodiment) For example, in the above-described first embodiment, the weight 50A is provided at a position in the front-rear direction Da that overlaps with the support shaft 4 when viewed from the up-down direction Dv, but this is not limiting. FIG. 7 is a diagram showing a first modified example of the tabletop-equipped fixture 1 according to the first embodiment of the present invention. 7, in the top plate 40B of the tabletop-equipped fixture 1 in this modified example, a weight 50B is provided at a position rearward of the support shaft 4. In this modified example, the weight 50B extends elongatedly in the width direction Dw, similar to the second reinforcing beam 44B in the above embodiment, and also functions as a reinforcing member for the lower plate 41 and the upper plate 42.

[0060] In a modification of this embodiment, the weight 50B is provided at a position rearward of the support shaft 4. According to this configuration, when the tabletop 40A is rotated from the use position P1 to the flip-up position P2, the tabletop 40A can be easily raised.

[0061] (Second Modification of the First Embodiment) FIG. 8 is a diagram showing a second modified example of the tabletop-equipped fixture 1 according to the first embodiment of the present invention. As shown in FIG. 8, in the tabletop 40C of the tabletop-equipped furniture 1 in this modified example, a weight 50C is provided in a position forward of the support shaft 4.

[0062] In a modification of this embodiment, the weight 50C is provided in front of the support shaft 4. According to this configuration, when the table top 40A is rotated from the use position P1 to the flip-up position P2, the weight 50C suppresses the rotation of the table top 40A. This makes it possible to prevent the table top 40A from rotating too forcefully.

[0063] Second embodiment Next, a second embodiment of the tabletop-equipped display unit according to the present invention will be described. In the second embodiment described below, the same components as those in the first embodiment will be denoted by the same reference numerals in the drawings, and the description thereof will be omitted. FIG. 9 is a plan view showing a state in which the top plate 40D of the tabletop-equipped fixture 1 according to the second embodiment of the present invention has the upper plate 42 removed. As shown in FIG. 9, the top plate 40D includes a lower plate 41, an upper plate 42 (see FIG. 6), a frame member 43, a reinforcing beam 44, a cushioning material 47, and a weight 50D. In this embodiment, the reinforcing beams 44 include only a first reinforcing beam 44A.

[0064] The weight 50D is provided at a distance from the first reinforcing beam 44A to the rear. The weight 50D extends in the width direction Dw. Specifically, the weight 50D is provided so as to straddle a pair of leg members 12 when viewed from the up-down direction Dv. The weight 50D is provided so as to overlap the tabletop side arm 262 when viewed from the up-down direction Dv. Both ends 50s of the weight 50D in the width direction Dw protrude further to both sides in the width direction Dw than the tabletop side arm 262. As a result, the load from above in the vertical direction supported by the weight 50D is transmitted to the pair of leg members 12 (pillars 13).

[0065] The weight 50D is accommodated in the internal space S of the main body 40T of the top plate 40D. The weight 50D applies a vertically downward load to the main body 40T of the top plate 40D. The weight 50D is formed in a solid block shape. A part of the weight 50D is provided on the opposite side to the side where the overhang portion 40S1 is provided, across the leg member 12R on the side where the overhang portion 40S1 is provided on one side in the width direction Dw of the leg member 12. Also, a part of the weight 50D is provided on the opposite side to the side where the overhang portion 40S2 is provided, across the leg member 12L on the side where the overhang portion 40S2 is provided on the other side in the width direction Dw of the leg member 12.

[0066] FIG. 10 is a cross-sectional view taken along line AA of FIG. The weight 50D is, for example, adhered to the upper surface of the lower plate 41. As shown in Fig. 9 and Fig. 10, in this embodiment, the top plate 40D has a positioning portion 70 that positions the weight 50D in a plane along the upper surface of the lower plate 41. The positioning portion 70 has, for example, a positioning protrusion 71 and a positioning recess 72.

[0067] A plurality of positioning protrusions 71 are provided at predetermined positions on the upper surface of the lower plate 41. In this embodiment, the positioning protrusions 71 are provided in, for example, two locations. The positioning protrusions 71 may be provided in three or more locations. As shown in Fig. 10, the positioning protrusions 71 protrude upward from the upper surface of the lower plate 41. The positioning recesses 72 are formed on the lower surface of the weight 50D. The positioning recesses 72 are formed in the same number as the positioning protrusions 71, at positions corresponding to each of the positioning protrusions 71. Each positioning recess 72 is formed so as to be recessed upward from the lower surface of the weight 50D.

[0068] When attaching weight 50D to the upper surface of lower plate 41, positioning portion 70 positions weight 50D relative to lower plate 41 by inserting each of the multiple positioning protrusions 71 into each of the multiple positioning recesses 72. Further, the weight 50D is formed with an escape hole 76 for avoiding interference with a nut 75 to which a bolt for joining the top plate side arm 262 and the lower plate 41 is fastened, for example.

[0069] By providing such weights 50D, the average value of the mass per unit area of ​​the main body 40T when viewed from the up-down direction Dv of the tabletop 40D is greater than that of the overhanging portions 40S. Also, the weight of the entire main body 40T including the weights 50D is greater than the weight of one of the overhanging portions 40S. In this embodiment, the weight of the entire main body 40T is greater than the combined weight of each of the overhanging portions 40S.

[0070] In this manner, in this embodiment, the main body portion 40T of the tabletop 40D is configured so that the average value of the mass per unit area when viewed in the up-down direction Dv is greater than that of the overhang portion 40S. According to this configuration, when a vertically downward load acts on one of the overhanging portions 40S in the width direction Dw, the mass of the main body portion 40T prevents the leg member 12 on the other side in the width direction Dw from being lifted. As a result, even when a vertically downward load acts on the overhanging portion 40S, the installation stability of the tabletop-equipped fixture 1 can be improved. In this case, by giving priority to the weight of the main body portion 40T, the tabletop 40D as a whole can be made lighter and thinner than when the weight of the entire tabletop 40D is ensured to improve installation stability.

[0071] In this embodiment, a weight 50D is provided on the main body 40T. With this configuration, the average mass per unit area of ​​the main body 40T of the tabletop 40D when viewed from the up-down direction Dv can be easily made larger than that of the overhanging portion 40S. Also, by adjusting the mass of the weight 50D according to the outward projection dimension of the overhanging portion 40S in the width direction Dw, the installation stability of the tabletop-equipped fixture 1 can be appropriately improved.

[0072] In this embodiment, of the pair of leg members 12, at least a portion of the weight 50D is provided on the side opposite the side on which the overhang portion 40S is provided, sandwiching the leg member 12 on which the overhang portion 40S is provided in the width direction Dw. With this configuration, when a vertically downward load acts on the overhang portion 40S, the mass of the weight 50D prevents the side opposite the leg member 12 on which the overhang portion 40S is provided from lifting up in the width direction Dw. As a result, even when a load acts on the overhang portion 40S, the installation stability of the tabletop-equipped fixture 1 can be improved.

[0073] In this embodiment, weight 50D is bonded to the upper surface of lower plate 41 and further includes a positioning portion 70 for positioning weight 50D relative to lower plate 41 in a plane along the upper surface. According to this configuration, the positioning portion 70 can position the weight 50D relative to the lower plate 41 in a plane along the upper surface of the lower plate 41, improving workability when adhering the weight 50D to the upper surface of the lower plate 41.

[0074] The weight 50D extends in the width direction Dw and is configured to straddle the pair of leg members 12 when viewed in the up-down direction Dv. According to this configuration, since the weight 50D extends in the width direction Dw, the weight 50D contributes to improving the strength of the tabletop 40D in the width direction Dw. Furthermore, since the weight 50D is provided so as to straddle the pair of leg members 12 when viewed from above, the strength of the tabletop 40D supported from below by the pair of leg members 12 is particularly increased. In this way, by making the weight 50D function as a reinforcing element for the tabletop 40D, the weight 50D can be provided in place of the second reinforcing beam 44B shown in the first embodiment. This makes it possible to reduce the number of parts constituting the tabletop-equipped furniture 1.

[0075] (Modification of the embodiment) In the above embodiment, the shape of the table top 40A is a hexagon when viewed from above, but is not limited thereto. The shape of the table top 40A may be a polygon other than a hexagon when viewed from above, an oval shape, an ellipse shape, a sector shape, or the like. Furthermore, the arrangement of weights 50A-50D as shown in the above-described embodiment can be appropriately modified as shown in the multiple modified examples described below, so long as at least a portion of the weights 50A-50D is provided on the side opposite to the side on which overhang portion 40S is provided, sandwiching the leg member 12 on which overhang portion 40S is provided in the width direction Dw, of a pair of leg members 12.

[0076] FIG. 11 is a plan view of a top plate 40E of a tabletop-equipped fixture 1 according to a modified example of the above embodiment. 11, the tabletop 40E in this modification has a rectangular shape in a plan view. In such a tabletop 40E, the weight 50E may be disposed in the center in the front-rear direction Da. In this modification, the weight 50E is disposed between the pair of leg members 12 over the entire width direction Dw. With such a configuration, it is possible to achieve the same effects as those shown in the above-described embodiments and modified examples.

[0077] FIG. 12 is a plan view of a top plate 40F of a tabletop-equipped fixture 1 according to another modified example of the above embodiment. 12, in the tabletop 40F of this modified example, the weight 50F also extends in the width direction Dw, and both ends in the width direction Dw protrude on both sides in the width direction Dw with respect to the pair of leg members 12. The weight 50F is provided so as to straddle the pair of leg members 12 when viewed from the up-down direction Dv. With such a configuration, it is possible to achieve the same effects as those shown in the above-described embodiments and modified examples.

[0078] FIG. 13 is a plan view of a top plate 40G of a top plate-equipped fixture 1 according to yet another modified example of the above embodiment. 13, the tabletop 40G in this modification includes a pair of weights 50G spaced apart in the width direction Dw. Each weight 50G is arranged to straddle one of the leg members 12 in the width direction Dw when viewed from the up-down direction Dv. Each weight 50G extends in the width direction Dw and protrudes inward and outward from the leg members 12 in the width direction Dw. In this case, one of the pair of weights 50G, weight 50G1, is provided on the opposite side to the side where overhang portion 40S1 is provided, across leg member 12R on the side where overhang portion 40S1 is provided on one side in the width direction Dw of leg member 12. The other weight 50G2 is provided on the opposite side to the side where overhang portion 40S2 is provided, across leg member 12L on the side where overhang portion 40S2 is provided on the other side in the width direction Dw of leg member 12.

[0079] In a modified example of the above embodiment, weights 50G1 and G2 are provided on the side of the pair of leg members 12 opposite the side on which the overhang portion 40S is provided, sandwiching the leg member 12 on which the overhang portion 40S is provided in the width direction Dw. With this configuration, when a vertically downward load acts on one of the overhanging portions 40S, the mass of the weights 50G1, G2 prevents the side opposite the leg member 12 on which the overhanging portion 40S is provided from lifting up in the width direction Dw. As a result, even when a load acts on the overhanging portion 40S, the installation stability of the tabletop-equipped fixture 1 can be improved.

[0080] FIG. 14 is a plan view of a top plate 40H of a top plate-equipped fixture 1 according to yet another modified example of the above embodiment. 14, the tabletop 40H in this modification includes a pair of weights 50H spaced apart in the width direction Dw. When viewed from the up-down direction Dv, each weight 50H is provided on either side of the pair of leg members 12 in the width direction Dw. Each weight 50H extends in the width direction Dw. In this case, one weight 50H1 is provided on the opposite side to the side where the overhang portion 40S1 is provided, across the leg member 12R on the side where the overhang portion 40S1 is provided on one side in the width direction Dw of the leg member 12. The other weight 50H2 is provided on the opposite side to the side where the overhang portion 40S2 is provided, across the leg member 12L on the side where the overhang portion 40S2 is provided on the other side in the width direction Dw of the leg member 12.

[0081] In a modified example of the above embodiment, weights 50H1 and H2 are provided on the side of the pair of leg members 12 opposite the side on which the overhang portion 40S is provided, sandwiching the leg member 12 on which the overhang portion 40S is provided in the width direction Dw. With this configuration, when a vertically downward load acts on one of the overhanging portions 40S, the mass of the weights 50H1, H2 prevents the side opposite the leg member 12 on which the overhanging portion 40S is provided from lifting up in the width direction Dw. As a result, even when a load acts on the overhanging portion 40S, the installation stability of the tabletop-equipped fixture 1 can be improved.

[0082] FIG. 15 is a plan view of a top plate 40I of a top plate-equipped fixture 1 according to yet another modified example of the above embodiment. 15, in the tabletop 40I of this modification, the weight 50I extends in the front-rear direction Da. In this modification, the weight 50I is entirely disposed between a pair of leg members 12. The weight 50I is disposed in the center of the body portion 40T in the width direction Dw. With such a configuration, it is possible to achieve the same effects as those shown in the above-described embodiments and modified examples.

[0083] FIG. 16 is a plan view of a top plate 40J of a top plate-equipped fixture 1 according to yet another modified example of the above embodiment. 16, the tabletop 40J in this modification includes a pair of weights 50J spaced apart in the width direction Dw. The pair of weights 50J are provided on the inside in the width direction Dw, i.e., on the main body 40T, of the pair of leg members 12. Each weight 50J extends in the front-rear direction Da. In this case, one weight 50J1 is provided on the opposite side to the side where the overhang portion 40S1 is provided, across the leg member 12R on the side where the overhang portion 40S1 is provided on one side in the width direction Dw of the leg member 12. The other weight 50J2 is provided on the opposite side to the side where the overhang portion 40S2 is provided, across the leg member 12L on the side where the overhang portion 40S2 is provided on the other side in the width direction Dw of the leg member 12.

[0084] In a modified example of the above embodiment, weights 50J1 and J2 are provided on the side of the pair of leg members 12 opposite the side on which the overhang portion 40S is provided, sandwiching the leg member 12 on which the overhang portion 40S is provided in the width direction Dw. With this configuration, when a vertically downward load acts on one of the overhanging portions 40S, the mass of the weights 50J1, J2 prevents the side opposite the leg member 12 on which the overhanging portion 40S is provided from lifting up in the width direction Dw. As a result, even when a load acts on the overhanging portion 40S, the installation stability of the tabletop-equipped fixture 1 can be improved.

[0085] FIG. 17 is a plan view of a tabletop 40K of a tabletop-equipped fixture 1 according to yet another modified example of the above embodiment. 17, the tabletop 40K in this modification includes a pair of weights 50K spaced apart in the width direction Dw. The pair of weights 50K are provided outside the pair of leg members 12 in the width direction Dw. Each weight 50K extends in the front-rear direction Da. Even in this case, one weight 50K1 is provided on the opposite side to the side where the overhang portion 40S1 is provided, across the leg member 12R on the side where the overhang portion 40S1 is provided on one side in the width direction Dw of the leg member 12. The other weight 50K2 is provided on the opposite side to the side where the overhang portion 40S2 is provided, across the leg member 12L on the side where the overhang portion 40S2 is provided on the other side in the width direction Dw of the leg member 12.

[0086] In a modified example of the above embodiment, weights 50K1 and K2 are provided on the side of the pair of leg members 12 opposite the side on which the overhang portion 40S is provided, sandwiching the leg member 12 on which the overhang portion 40S is provided in the width direction Dw. With this configuration, when a vertically downward load acts on one of the overhanging portions 40S, the mass of the weights 50K1, K2 prevents the side opposite the leg member 12 on which the overhanging portion 40S is provided from lifting up in the width direction Dw. As a result, even when a load acts on the overhanging portion 40S, the installation stability of the tabletop-equipped fixture 1 can be improved.

[0087] In the above-described embodiment and its modified example, the overhang portion 40S is provided on both sides in the width direction Dw, but this is not limited thereto. The overhang portion 40S may be provided on only one side in the width direction Dw. FIG. 18 is a plan view of a top plate 40L of a top plate-equipped fixture 1 according to yet another modified example of the above embodiment. 18, the tabletop 40L in this modification has an overhang portion 40S only on one side in the width direction Dw with respect to the main body 40T. In such a tabletop 40L, the weight 50L may be disposed on the main body 40T between the pair of leg members 12 over the entire width direction Dw. In this modification, the weight 50L extends in the width direction Dw. The weight 50L may also extend in the front-rear direction Da.

[0088] In such a configuration, the weight 50L is provided on the opposite side to the side on which the overhang portion 40S is provided, across the leg member 12R of the pair of leg members 12 on which the overhang portion 40S is provided in the width direction Dw. With this configuration, when a vertically downward load acts on the overhang portion 40S, the mass of the weight 50L prevents the side opposite the leg member 12R on which the overhang portion 40S is provided from being lifted in the width direction Dw. As a result, even when a load acts on the overhang portion 40S, the installation stability of the tabletop-equipped fixture 1 can be improved.

[0089] FIG. 19 is a plan view of a top plate 40M of a top plate-equipped fixture 1 according to another modified example of the above embodiment. 19, in the tabletop 40M of this modification, the weight 50M extends in the width direction Dw, and both ends in the width direction Dw protrude on both sides in the width direction Dw relative to the pair of leg members 12. One end 50z of the weight 50M in the width direction Dw extends into the overhang portion 40S. When viewed from the up-down direction Dv, the weight 50M is provided so as to straddle the pair of leg members 12, and functions as a reinforcing element for the tabletop 40.

[0090] Even in such a configuration, a portion 50x of the weight 50M is provided on the side opposite the side on which the overhang portion 40S is provided, sandwiching the leg member 12R on which the overhang portion 40S is provided in the width direction Dw. With this configuration, when a vertically downward load acts on the overhang portion 40S, the mass of the portion 50x of the weight 50M prevents the side opposite the leg member 12R on which the overhang portion 40S is provided from lifting up in the width direction Dw. As a result, even when a load acts on the overhang portion 40S, the installation stability of the tabletop-equipped fixture 1 can be improved.

[0091] FIG. 20 is a plan view of a top plate 40N of a top plate-equipped fixture 1 according to yet another modified example of the above embodiment. 20, the tabletop 40N in this modification includes a weight 50N disposed on the main body 40T on the side away from the overhang portion 40S in the width direction Dw. The weight 50N may extend in the width direction Dw. The weight 50N may also extend in the front-rear direction Da. In this case, the weight 50N is provided on the side of the leg member 12 opposite to the side on which the overhang portion 40S is provided, across the leg member 12R on the side on which the overhang portion 40S is provided.

[0092] With this configuration, when a vertically downward load acts on the overhang portion 40S, the mass of the weight 50N prevents the side opposite the leg member 12R on which the overhang portion 40S is provided from lifting up in the width direction Dw. As a result, even when a load acts on the overhang portion 40S, the installation stability of the tabletop-equipped fixture 1 can be improved.

[0093] (Other Modifications of the Embodiments) In the above embodiment, the weights 50A-50N are provided on the main body 40T to make the average mass of the main body 40T and the overhanging portion 40S different, but the present invention is not limited to this configuration. The average mass of the main body 40T and the overhanging portion 40S may be made different by making the thickness of the main body 40T and the overhanging portion 40S different. In the above embodiment, the top plates 40A-40K having the overhang portions 40S on both sides in the width direction Dw are formed line-symmetrically in the width direction, but the present invention is not limited to this configuration. The top plates 40A-40K may be formed asymmetrically. Furthermore, the top plates 40A-40K may be formed line-symmetrically in the width direction and the front-rear direction, such as a rectangular or circular shape.

[0094] In the above embodiment, the table tops 40A to 40D are configured to be rotatable around the support shaft 4, but this is not limiting. In the above embodiment, the lower end of each leg column 13 and the rear end of each support leg 14 are provided with casters 15, but this is not limited to the above. The lower end of each leg column 13 and the rear end of each support leg 14 may not be provided with casters 15. In addition, within the scope of the invention, the components in the above-described embodiments may be replaced with well-known components, and the above-described modified examples may be combined as appropriate.
