Description

Technical Field

[0001] The present invention relates to a furniture with a top plate.

Background Art

[0002] Some furniture with a top plate such as a desk has a desktop panel attached to the edge of the top plate as viewed from above and below. The desktop panel extends upward from the top plate and serves to partition the working space on the top plate and other spaces. Patent Document 1 discloses a furniture with a top plate that is attached so as to be movable in a direction approaching or separating the desktop panel from the edge of the top plate as viewed from above and below. In such a furniture with a top plate, by widening the gap between the edge of the top plate and the desktop panel, wiring can be easily passed through the gap.

[0003] In the furniture with a top plate of Patent Document 1, a long hole (through hole) extending in the moving direction of the desktop panel is formed in a connection member provided on the desktop panel. Then, by passing a screw member through the long hole and screwing it into the female screw of the top plate, the desktop panel can be moved relative to the top plate. Further, by fastening the connection member to the top plate with a screw member, the desktop member is fixed to the top plate so as not to be movable.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in conventional furniture with a tabletop, such as that described in Patent Document 1, optional elements such as desktop panels are fixed to the tabletop only by screw members passed through elongated holes in the connecting members. As a result, the load caused by the weight of the optional elements is concentrated on the screw members passed through the elongated holes. This leads to the problem that the fixing part between the tabletop and the optional elements deteriorates over time. When the fixing part between the tabletop and the optional elements deteriorates, the fixing force of the screw members decreases, and there is a possibility that the optional elements may move unexpectedly relative to the tabletop.

[0006] This invention has been made in view of the above circumstances, and aims to provide a fixture with a tabletop that can suppress the deterioration of the fixing portion between the tabletop and the optional element over time. [Means for solving the problem]

[0007] (1) Embodiment 1 of the fixture with a top plate according to the present invention comprises a top plate having an upper surface and a lower surface facing the opposite side of the upper surface, a support structure that supports the top plate from below, an optional element attached to the top plate, and a fixing structure that moves the optional element relative to the top plate in a linear direction along the upper and lower surfaces, thereby changing the gap between the edge of the top plate and the optional element in a plan view from the top and bottom, and fixing the optional element to the top plate so that it cannot move, wherein the fixing structure comprises a first female screw and a second female screw formed in the first component of the top plate and the optional element, and the top plate and the optional element The present invention is characterized by comprising: an elongated hole formed in the second component, penetrating in the vertical direction and extending in the linear direction, and facing the first female thread in the vertical direction; a through hole formed in the second component, penetrating in the vertical direction and facing the second female thread in the vertical direction, and having the same size and shape as the second female thread when viewed from the vertical direction; a first screw member that passes through the elongated hole and is screwed into the first female thread, thereby sandwiching the second component between itself and the first component; and a second screw member that passes through the through hole and is screwed into the second female thread, thereby sandwiching the second component between itself and the first component.

[0008] In the fixture with a top plate according to Embodiment 1, the optional element can be fixed to the top plate so as not to move by passing a first screw member and a second screw member through the elongated holes and through-holes formed in the top plate and the second component of the optional element, respectively, and then screwing them into the first female threads and second female threads formed in the top plate and the first component of the optional element, respectively. The optional element is fastened and fixed to the top plate not only by the first screw member passed through the elongated holes, but also by the second screw member passed through the through-holes. This prevents the load caused by the weight of the optional element from concentrating on the first screw member passed through the elongated holes. Therefore, deterioration of the fixing part between the top plate and the optional element over time can be suppressed.

[0009] Furthermore, in the fixture with a top plate according to Embodiment 1, the insertion hole of the panel device and the second female screw of the top plate are of the same size and shape when viewed from above. This prevents or suppresses the panel device from moving unexpectedly relative to the top plate, as the second screw member is passed through the insertion hole and then screwed into the second female screw.

[0010] Furthermore, in the fixture with a top plate according to Embodiment 1, the option element can be moved linearly relative to the top plate by removing the second screw member from the second female thread and insertion hole, and by releasing the fastening state of the option element by the first screw member, while keeping the first screw member screwed into the first female thread by passing it through the elongated hole. In other words, the gap between the option element and the edge of the top plate can be changed in a plan view seen from above and below.

[0011] (2) Embodiment 2 of the fixture with a top plate according to the present invention is, in Embodiment 1, the optional element is arranged to overlap the upper or lower surface of the top plate in the vertical direction and has a mounting plate portion that is attached to the top plate, the first female screw and the second female screw are formed in the top plate, and the elongated hole and the through hole are formed in the mounting plate portion.

[0012] In this configuration of a fixture with a tabletop, it becomes unnecessary to create elongated holes in the tabletop. Furthermore, creating elongated holes in the mounting plate is easier than creating them in the tabletop. Therefore, it becomes possible to easily manufacture fixtures with tabletops.

[0013] (3) Embodiment 3 of the fixture with a top plate according to the present invention is, in Embodiment 2, the mounting plate portion may have an opening formed in the outer edge of the mounting plate portion, such that the elongated hole opens when viewed in a plan view from the top and bottom direction.

[0014] In this configuration of a fixture with a top plate, the shaft of the first threaded member, which is screwed into the first female thread, can move in and out of the elongated hole by passing through the opening in the mounting plate. In other words, with the first threaded member screwed into the first female thread, the shaft of the first threaded member can be moved in and out of the elongated hole. Therefore, optional elements can be easily attached to and detached from the top plate.

[0015] (4) Embodiment 4 of the fixture with a top plate according to the present invention is that in Embodiment 3, the opening may extend in a direction that intersects the linear direction in a plan view as seen from the up and down direction.

[0016] In a fixture with a tabletop configured in this way, when the optional elements are slid linearly relative to the tabletop, it is possible to effectively prevent the optional elements from accidentally detaching from the tabletop.

[0017] (5) Embodiment 5 of the fixture with a top plate according to the present invention is such that, in Embodiment 3 or Embodiment 4, the opening may be located away from both ends of the elongated hole in the linear direction.

[0018] In a fixture with a tabletop configured in this way, when a user slides an optional element linearly relative to the tabletop, the optional element is often positioned in either a first position where the shaft of the first screw member contacts the first end of the elongated hole in the linear direction, or a second position where the shaft of the first screw member contacts the second end of the elongated hole in the linear direction. Therefore, by positioning the opening away from both ends (first and second ends) of the elongated hole, it is possible to reliably prevent the optional element from accidentally detaching from the tabletop, even when it is positioned in the first or second position.

[0019] (6) In any of embodiments 3 to 5 of the fixture with a top plate according to the present invention, it is preferable that the optional element has a plurality of mounting plate portions, and the direction in which the opening extends in a plan view from the top and bottom is the same among the plurality of mounting plate portions.

[0020] In a display unit with a tabletop configured in this way, even if the optional elements are large or heavy enough to require the user to hold them with both hands, attaching and detaching the optional elements from the tabletop becomes easier and safer.

[0021] (7) In any of embodiments 1 to 6 of the present invention, embodiment 7 of the fixture with a top plate may be such that, in a plan view from the top and bottom, the difference between the diameter of the first female screw and the width of the elongated hole is greater than the difference between the diameter of the second female screw and the diameter of the insertion hole.

[0022] In a fixture with a top plate configured in this way, the gap between the shaft of the first female screw member and the inner surface of the elongated hole when the first screw member is passed through the elongated hole and screwed into the first female screw is larger than the gap between the shaft of the second screw member and the inner surface of the through hole when the second screw member is passed through the through hole and screwed into the second female screw. Therefore, when the second screw member is passed through the insertion hole and screwed onto the second female screw, the rattling of the option element with respect to the top plate can be reduced as compared with the state where the second screw member is removed from the insertion hole and the second female screw. Thereby, the integrality of the top plate fixture including the top plate and the option element can be improved. On the other hand, although the first screw member is passed through the long hole and screwed onto the first female screw, in the state where the second screw member is removed from the insertion hole and the second female screw, the option element can be moved greatly in the width direction of the long hole as compared with the state where the second screw member is passed through the insertion hole and screwed onto the second female screw. Thereby, the slide movement of the option element with respect to the top plate can be performed smoothly.

Advantages of the Invention

[0023] According to the present invention, it is possible to suppress the aging deterioration of the fixing portion between the top plate and the option element.

[Modes for carrying out the invention]

[0025] An embodiment of the present invention will be described below with reference to the attached drawings. As shown in Figure 1, the furniture with a tabletop 1 is, for example, a desk and is placed on the floor surface F. As shown in Figures 1 and 2, the furniture with a tabletop 1 comprises a tabletop 2, a support structure 3, a panel device 4 (optional element), and a fixing structure 5.

[0026] In the following explanation, the direction perpendicular to the floor surface F is defined as the vertical direction Dv, the direction in which the panel device 4 extends within the plane perpendicular to the vertical direction Dv is defined as the width direction Dw, and the direction intersecting the vertical direction Dv and the width direction Dw is defined as the front-to-back direction Da.

[0027] The top plate 2 is plate-shaped and provided along a surface that intersects the vertical direction Dv. The top plate 2 has an upper surface 2a that faces upward in the vertical direction Dv, and a lower surface 2b that faces downward in the vertical direction Dv (facing the opposite side of the upper surface 2a). The upper surface 2a of the top plate 2 functions as a work surface for the user of the furniture with a top plate 1. In this embodiment, the top plate 2, when viewed from above, is formed in a rectangular shape, for example, with the width direction Dw as the long sides 21A and 21B, and the front-to-back direction Da as the short side 22.

[0028] As shown in Figure 1, the support structure 3 supports the top plate 2 from below. The support structure 3 is placed on the floor surface F at the location where the furniture with the top plate 1 is installed. The support structure 3 in this embodiment has a pair of support legs 31 and a connecting rod 32.

[0029] A pair of support legs 31 are spaced apart in the width direction Dw. Each support leg 31 is formed in a rectangular frame shape when viewed from the width direction Dw and has a pair of leg members 34, 35, a lower connecting member 36, and an upper connecting member 37.

[0030] The pair of leg members 34 and 35 are spaced apart in the front-rear direction Da. Each leg member 34 and 35 extends in the vertical direction Dv. In this embodiment, the leg member 34 positioned in front of the pair of leg members 34 and 35 in the front-rear direction Da is located below the tabletop 2. The leg member 35 positioned in rear of the pair of leg members 34 and 35 is located behind the tabletop 2 and is longer in the vertical direction Dv than the leg member 34 positioned in front. The leg members 34 and 35 may have a structure that allows them to extend and retract in the vertical direction Dv. In this case, by extending the leg members 34 and 35 so that the tabletop 2 is positioned higher in the vertical direction Dv, it is possible for the user to operate the fixing structure 5 described later.

[0031] The lower connecting member 36 extends in the front-rear direction Da and connects the lower ends of the pair of leg members 34 and 35. Both ends of the lower connecting member 36 in the front-rear direction Da are fixed to each of the pair of leg members 34 and 35 by means of welding, screwing, or other means. The upper connecting member 37 extends in the front-rear direction Da and connects the upper ends of the pair of leg members 34 and 35. Both ends of the upper connecting member 37 in the front-rear direction Da are fixed to each of the pair of leg members 34 and 35 by means of welding, screwing, or other means.

[0032] The connecting rod 32 extends in the width direction Dw and connects the pair of support legs 31. In Figure 1, the connecting rod 32 connects the intermediate parts in the vertical direction Dv of the rearward-positioned leg member 35 of the pair of support legs 31. Each end of the connecting rod 32 in the width direction Dw is fixed to the leg member 35 of the pair of support legs 31 by means of welding, screwing, or other means. Although not shown, the connecting rod 32 may also connect the intermediate parts in the front-rear direction Da of the upper connecting member 37 of the pair of support legs 31. In this case, each end of the connecting rod 32 in the width direction Dw may be fixed to the upper connecting member 37 of the pair of support legs 31 by means of welding, screwing, or other means.

[0033] The aforementioned top plate 2 is connected to the support structure 3 described above with bolts (not shown) or the like. The top plate 2 may also be connected with bolts or the like to, for example, the two upper connecting members 37 of the support structure 3 or the connecting rods that connect them.

[0034] As shown in Figures 1 to 3, the panel device 4 is attached to the tabletop 2 by a fixing structure 5, which will be described later. The panel device 4 extends upward from the edge of the tabletop 2 as viewed from the vertical direction Dv, thereby separating the workspace on the upper surface 2a of the tabletop 2 from other spaces. The edge of the tabletop 2 includes the edge of the tabletop 2 or the area near it.

[0035] In this embodiment, the panel device 4 is located on or near the rearmost long side 21B of the top plate 2, as viewed from the vertical direction Dv. Furthermore, the panel device 4 extends across the entire long side 21B of the top plate 2 in the width direction Dw. That is, the width dimension Dw of the panel device 4 is equivalent to (or slightly different from) the width dimension Dw of the top plate 2. However, the width dimension Dw of the panel device 4 may differ significantly from the width dimension Dw of the top plate 2.

[0036] The panel device 4 includes a panel 41 and a support portion 42. Panel 41 separates the workspace on the upper surface 2a of the top plate 2 from other spaces, and only needs to be formed in a plate shape. In this embodiment, panel 41 is formed in a flat plate shape with the front-to-back direction Da as the thickness direction, and extending in the width direction Dw and the up-to-down direction Dv. Also, in this embodiment, panel 41 extends in the width direction Dw over almost the entire length of the long side 21B of the top plate 2. The specific materials and components of panel 41 are arbitrary. Panel 41 may be, for example, a resin plate with its surface covered with nonwoven fabric, or it may be composed solely of nonwoven fabric. In the panel 41 illustrated in Figure 3, recesses 411 are formed at both ends in the width direction Dw of the lower end of the panel 41, which is supported by a support portion 42 described later. Each recess 411 is shaped to be recessed upward relative to the lower edge of the panel 41 when viewed from the front-rear direction Da.

[0037] As shown in Figures 2 and 3, the support portion 42 supports the panel 41. Specifically, the support portion 42 supports the lower end of the panel 41 and has the role of standing the panel 41 upright in the vertical direction Dv on the top plate 2. The support portion 42 also supports the panel 41 in a detachable manner. The support portion 42 has a first upright portion 44, a second upright portion 45, and a bracket 46.

[0038] The first upright portion 44 and the second upright portion 45 are positioned on both sides of the panel 41 in the front-rear direction Da (thickness direction of the panel 41), and support the lower end of the panel 41 from the front-rear direction Da. The first upright portion 44 and the second upright portion 45 are arranged sequentially towards the rear. The first upright portion 44 and the second upright portion 45 are formed separately and connected to each other via a bracket 46, which will be described later.

[0039] In this embodiment, the first upright portion 44 and the second upright portion 45 are formed in a flat plate shape with the front-to-back direction Da as the thickness direction, and extending in the width direction Dw and the vertical direction Dv. However, the vertical dimension Dv of the first upright portion 44 and the second upright portion 45 is sufficiently smaller than the vertical dimension Dv of the panel 41. Furthermore, the first upright portion 44 and the second upright portion 45 are formed in a strip shape with the width direction Dw sufficiently larger than the vertical dimension Dv. In addition, the first upright portion 44 and the second upright portion 45 extend in the width direction Dw over almost the entire length of the long sides 21A and 21B of the top plate 2, respectively.

[0040] The specific materials and components of the first upright portion 44 and the second upright portion 45 may be arbitrary. In this embodiment, the first upright portion 44 and the second upright portion 45 are made of metal plates. The first upright portion 44 and the second upright portion 45 may have the same configuration as, for example, the panel 41 described above.

[0041] As shown in Figure 2, the bracket 46 is a component formed integrally with a connecting plate portion 461 and a mounting plate portion 462. The connecting plate portion 461 is formed in the shape of a strip plate with the front-to-back direction Da as the thickness direction and extending in the up-to-down direction Dv. The mounting plate portion 462 is formed in the shape of a strip plate with the up-to-down direction Dv as the thickness direction and extending in the front-to-back direction Da. The mounting plate portion 462 extends forward from the lower end of the connecting plate portion 461. Therefore, the bracket 46 is formed in an L-shape when viewed from the width direction Dw. In this embodiment, the bracket 46 is constructed by bending a metal strip plate into an L-shape.

[0042] The connecting plate portion 461 is positioned between the first upright portion 44 and the second upright portion 45 in the front-rear direction Da described above. The connecting plate portion 461 is interposed between the first upright portion 44 and the second upright portion 45 and functions as a spacer that defines the distance between the first upright portion 44 and the second upright portion 45 in the front-rear direction Da. The connecting plate portion 461 connects the first upright portion 44 and the second upright portion 45. Specifically, the connecting plate portion 461 is fixed to the first upright portion 44 by rivets 49. The connecting plate portion 461 is also fixed to the second upright portion 45 by welding. Note that the method of fixing the connecting plate portion 461 to the first upright portion 44 and the second upright portion 45 is not limited to these and may be arbitrary.

[0043] The mounting plate portion 462 is positioned overlapping the lower surface 2b of the top plate 2 in the vertical direction Dv and is attached to the top plate 2 by a fixing structure 5, which will be described later.

[0044] In this embodiment, one bracket 46 is placed at each end of the first upright portion 44 and the second upright portion 45 in the width direction Dw. The positions of the two brackets 46 (particularly the connecting plate portion 461) in the width direction Dw correspond to the positions of the two recessed portions 411 (see Figure 3) of the panel in the width direction Dw. Therefore, when the lower end of the panel 41 is inserted between the first upright portion 44 and the second upright portion 45, at least the upper end of the connecting plate portion 461 of the bracket 46 is inserted into the recessed portion 411. Also, the top of the recessed portion 411 abuts against the upper edge of the connecting plate portion 461. In other words, the panel 41 is supported from below by the connecting plate portion 461 of the bracket 46. This determines the position of the panel 41 in the vertical direction Dv relative to the support portion 42. The brackets 46 may be arranged in a row of three or more, spaced apart in the width direction Dw. Furthermore, the brackets 46 (especially the mounting plate portion 462) may extend for a long distance in the width direction Dw, for example. In this case, the number of brackets 46 may be, for example, just one.

[0045] As shown in Figures 4 and 7, the fixing structure 5 attaches the panel device 4 to the top plate 2 so that it can move in a linear direction along the lower surface 2b, thereby changing the gap G between the edge of the top plate 2 and the panel device 4 in a plan view from the vertical direction Dv. In addition, the fixing structure 5 fixes the panel device 4 to the top plate 2 so that it cannot move. In this embodiment, the "linear direction" corresponds to the front-to-back direction Da. Also, the "edge of the top plate 2" corresponds to the long side 21B of the top plate 2 located at the rear.

[0046] As shown in Figure 4, the fixing structure 5 includes a first female screw 51, a second female screw 52, ​​an elongated hole 53, a through hole 54, a first threaded member 55, and a second threaded member 56.

[0047] The first female thread 51 and the second female thread 52 are formed in the top plate 2 (first component). The sizes of the first female thread 51 and the second female thread 52 may be different, for example, but in this embodiment they are the same. The relative positional relationship of the first female thread 51 and the second female thread 52 as viewed from the vertical direction Dv is not limited to that illustrated in Figure 4.

[0048] The elongated holes 53 and through holes 54 are formed in the panel device 4 (second component). Specifically, the elongated holes 53 and through holes 54 are formed in the mounting plate portion 462 of the panel device 4. In this embodiment, the panel device 4 has a plurality of mounting plate portions 462, and one elongated hole 53 and one through hole 54 are formed in each of these mounting plate portions 462. The elongated hole 53 penetrates the mounting plate portion 462 in the vertical direction Dv and extends in the front-rear direction Da, and faces the first female screw 51 of the top plate 2 in the vertical direction Dv. The through-hole 54 penetrates the mounting plate portion 462 in the vertical direction Dv and faces the second female thread 52 in the vertical direction Dv. The through-hole 54 has the same size and shape as the second female thread 52 when viewed from the vertical direction Dv. That is, the through-hole 54 is formed as a circle of the same size as the second female thread 52 when viewed from the vertical direction Dv. Specifically, the diameter dimension D4 of the through-hole 54 is the same as or slightly larger than the diameter dimension D2 of the second female thread 52 (see Figure 5).

[0049] As shown in Figure 5, in a plan view from the vertical direction Dv, the difference between the diameter dimension D1 of the first female thread 51 and the width dimension W3 of the elongated hole 53 is the same as the difference between the diameter dimension D2 of the second female thread 52 and the diameter dimension D4 of the through hole 54. Note that the difference between the diameter dimension D1 of the first female thread 51 and the width dimension W3 of the elongated hole 53 may be larger than, for example, the difference between the diameter dimension D2 of the second female thread 52 and the diameter dimension D4 of the through hole 54. The above "width dimension W3 of the elongated hole 53" is the dimension of the elongated hole 53 in the direction perpendicular to the front-to-back direction Da in a plan view from the vertical direction Dv, that is, the dimension of the elongated hole 53 in the width direction Dw.

[0050] As shown in Figures 4 and 6, the first screw member 55 is passed through the elongated hole 53 and then screwed into the first female thread 51, thereby sandwiching the mounting plate portion 462 between it and the top plate 2. Specifically, by passing the shaft portion 551 of the first screw member 55 through the elongated hole 53 and then screwing it into the first female thread 51, the mounting plate portion 462 is sandwiched between the head 552 of the first screw member 55 and the top plate 2. By adjusting the state in which the first screw member 55 is screwed into the first female thread 51, the distance between the top plate 2 and the head 552 of the first screw member 55 can be made larger than the thickness of the mounting plate portion 462. When the distance between the top plate 2 and the head 552 of the first screw member 55 is larger than the thickness of the mounting plate portion 462, the mounting plate portion 462 is located between the top plate 2 and the head 552 of the first screw member 55, but is not sandwiched between them. In this state, the mounting plate portion 462 can be moved relative to the top plate 2 in the longitudinal direction (front-to-back direction Da) of the elongated hole 53 (see Figures 4 and 7).

[0051] The second screw member 56 is inserted through the through hole 54 and then screwed into the second female thread 52, thereby sandwiching the mounting plate portion 462 between it and the top plate 2. Specifically, similar to the case of the first screw member 55 illustrated in Figure 6, the shaft portion of the second screw member 56 is inserted through the elongated hole 53 and then screwed into the second female thread 52, so that the mounting plate portion 462 is sandwiched between the head of the second screw member 56 and the top plate 2. When the second screw member 56 is inserted through the through hole 54 of the mounting plate portion 462 and screwed into the second female thread 52 of the top plate 2, even if the mounting plate portion 462 is not sandwiched between the top plate 2 and the second screw member 56, it is possible to restrict the movement of the mounting plate portion 462 along the longitudinal direction of the elongated hole 53 along the lower surface 2b of the top plate 2. By sandwiching the mounting plate portion 462 between at least one of the first screw member 55 and the second screw member 56 described above and the top plate 2, the mounting plate portion 462 can be fixed to the top plate 2 in a way that prevents it from moving.

[0052] As shown in Figure 4, an opening 57 is formed in the mounting plate portion 462. In a plan view of the mounting plate portion 462 from the vertical direction Dv, the opening 57 forms an elongated hole 53 at the outer edge of the mounting plate portion 462. The opening 57 penetrates the mounting plate portion 462 in the vertical direction Dv and extends from the inner edge of the mounting plate portion 462 that forms the elongated hole 53 to the outer edge of the mounting plate portion 462. The size of the opening 57 in the direction intersecting the direction in which the opening 57 extends, as viewed from the vertical direction Dv, is set to allow the first screw member 55 (especially the shaft portion) to pass through.

[0053] In this embodiment, the opening 57 described above extends in a direction intersecting the longitudinal direction (linear direction) of the elongated hole 53 when viewed from the vertical direction Dv in a plan view of the mounting plate portion 462. Specifically, the opening 57 extends from the elongated hole 53 to the outer edge of the mounting plate portion 462 on one side in the width direction Dw (the left side in Figure 4). For this reason, the size of the opening 57 in the front-rear direction Da when viewed from the vertical direction Dv is set to allow the first screw member 55 (especially the shaft portion) to pass through.

[0054] In this embodiment, the opening 57 is located away from both ends in the longitudinal direction (linear direction) of the elongated hole 53. Here, the first end 531 of the elongated hole 53 is located on the base end side of the mounting plate portion 462. The second end 532 of the elongated hole 53 is located on the tip side of the mounting plate portion 462. In the illustrated example, the opening 57 is located in the middle of the elongated hole 53 in the longitudinal direction. The opening 57 may also be located offset from the middle of the elongated hole 53 towards the first end 531 side or the second end 532 side of the elongated hole 53.

[0055] The mounting plate portion 462, which has the elongated hole 53 and opening 57 described above, has a pair of projections 464 that form a part of the periphery of the elongated hole 53 when viewed from the vertical direction Dv. The pair of projections 464 extend in a direction that moves toward each other in the front-rear direction Da. The opening 57 described above is formed between the opposing surfaces 464a of the pair of projections 464 that are facing each other in the front-rear direction Da when viewed from the vertical direction Dv.

[0056] As shown in Figure 2, the brackets 46, which include the mounting plate portion 462 in which the elongated holes 53, insertion holes 54, and openings 57 (see Figure 4) of the fixing structure 5 described above are formed, are arranged in multiples with spacing in the width direction Dw, as previously mentioned. The direction in which the opening 57 extends from the elongated hole 53 to the outer edge of the mounting plate portion 462 is the same for all of the brackets 46. Specifically, in all of the brackets 46, as shown in Figure 4, the opening 57 extends from the elongated hole 53 to the outer edge of the mounting plate portion 462 on one side in the width direction Dw (the left side in Figure 4).

[0057] As shown in Figures 4 and 7, in the fixture 1 with a top plate of this embodiment, the mounting plate 462 can be moved relative to the top plate 2 in the longitudinal direction (front-to-back direction Da) of the elongated hole 53, with the first screw member 55 inserted through the elongated hole 53 of the mounting plate 462 and screwed into the first female thread 51 of the top plate 2, while the second screw member 56 is not screwed into the second female thread 52 of the top plate 2. As a result, the panel device 4 can be moved in the front-to-back direction Da relative to the top plate 2 while attached to the top plate 2 by the first screw member 55.

[0058] Specifically, the panel device 4 (particularly the panel 41, the first upright portion 44, and the second upright portion 45) is movable in the front-rear direction Da between a first position P1 where the shaft of the first screw member 55 contacts the first end 531 of the elongated hole 53, as shown in Figure 4, and a second position P2 where the shaft of the first screw member 55 contacts the second end 532 of the elongated hole 53 in the front-rear direction Da, as shown in Figure 7. As shown in Figures 4 and 7, in a plan view from the vertical direction Dv, the gap G2 between the panel device 4 positioned at the second position P2 and the long side 21B of the top plate 2 is larger than the gap G1 between the panel device 4 positioned at the first position P1 and the long side 21B of the top plate 2. As a result, in the fixture with a top plate 1 of this embodiment, the gap G between the long side 21B (edge) of the top plate 2 and the panel device 4 can be changed in the front-rear direction Da by moving the panel device 4 in the front-rear direction Da. When the panel device 4 is positioned at the second position P2, tasks such as inserting wiring through the gap G can be easily performed. Note that, for example, there does not need to be a gap G between the panel device 4 positioned at the first position P1 and the long side 21B of the top plate 2.

[0059] In the fixture with a top plate 1 of this embodiment, the panel device 4 can be attached to and detached from the top plate 2 while the first screw member 55 is screwed into the first female screw 51 of the top plate 2. For example, when removing the panel device 4 from the top plate 2, first, as shown in Figure 8, the panel device 4 is moved in the front-rear direction Da relative to the top plate 2, so that the first screw member 55, which is screwed into the first female screw 51, is positioned in the same position as the opening 57 in the front-rear direction Da. This position of the panel device 4 is called the third position P3. Then, by moving the panel device 4 to the other side in the width direction Dw (to the right in Figure 8), the shaft portion of the first screw member 55, which is screwed into the first female screw 51, passes through the opening 57 of the mounting plate portion 462 and comes out to the outside of the mounting plate portion 462. In other words, the mounting plate portion 462 is detached from the first screw member 55. This allows the panel device 4 to be removed from the top plate 2. To attach the panel device 4 to the top plate 2, simply reverse the removal procedure described above.

[0060] As described above, in the fixture with a top plate of this embodiment, the panel device 4 can be fixed immovably to the top plate 2 by passing the first screw member 55 and the second screw member 56 through the elongated hole 53 and the insertion hole 54 formed in the panel device 4 (second component), respectively, and then screwing them into the first female screw 51 and the second female screw 52 formed in the top plate 2 (first component), respectively. The panel device 4 is fastened and fixed to the top plate 2 not only by the first screw member 55 passed through the elongated hole 53, but also by the second screw member 56 passed through the insertion hole 54. This prevents the load caused by the weight of the panel device 4 from concentrating on the first screw member 55 passed through the elongated hole 53. Therefore, deterioration over time of the fixing portion between the top plate 2 and the panel device 4 can be suppressed.

[0061] Furthermore, in the fixture 1 with a top plate of this embodiment, the insertion hole 54 of the panel device 4 and the second female screw 52 of the top plate 2 are of the same size and shape when viewed from the vertical direction Dv. Therefore, when the second screw member 56 of the panel device 4 is passed through the insertion hole 54 and then screwed into the second female screw 52, ​​it is possible to suppress or prevent the panel device 4 from moving unexpectedly relative to the top plate 2.

[0062] In this embodiment, the fixture with a top plate 1 can be moved in the front-to-back direction Da (linear direction) relative to the top plate 2 by removing the second screw member 56 from the second female screw 52 and the insertion hole 54, and by releasing the fastening state of the panel device 4 to the top plate 2 by the first screw member 55, while keeping the first screw member 55 screwed into the first female screw 51 by passing it through the elongated hole 53. In other words, the gap G between the panel device 4 and the long side 21B (edge) of the top plate 2 can be changed in a plan view from the vertical direction Dv.

[0063] Furthermore, in the fixture with a top plate 1 of this embodiment, the elongated holes 53 are formed in the mounting plate portion 462 of the panel device 4, which is placed on top of the lower surface 2b of the top plate 2. Therefore, it is unnecessary to process the top plate 2 to form the elongated holes 53. Moreover, forming the elongated holes 53 in the mounting plate portion 462 is easier than forming the elongated holes 53 in the top plate 2. Thus, the fixture with a top plate 1 can be easily manufactured.

[0064] Furthermore, in the fixture with a top plate 1 of this embodiment, the mounting plate portion 462 has an opening 57 formed in the outer edge of the mounting plate portion 462, which opens to the elongated hole 53 when viewed from the vertical direction Dv in a plan view. As a result, the shaft portion of the first screw member 55, which is screwed into the first female screw 51, can pass through the opening 57 in the mounting plate portion 462 and move in and out of the elongated hole 53. That is, with the first screw member 55 screwed into the first female screw 51, the shaft portion of the first screw member 55 can be moved in and out of the elongated hole 53. Therefore, the panel device 4 can be easily attached to and detached from the top plate 2.

[0065] Furthermore, in the fixture with a top plate 1 of this embodiment, the opening 57 extends in a direction that intersects the longitudinal direction (linear direction) of the elongated hole 53 when viewed from the vertical direction Dv in a plan view. Specifically, the opening 57 extends in the width direction Dw, which is perpendicular to the front-to-back direction Da, which is the longitudinal direction of the elongated hole 53. Therefore, when the panel device 4 is slid in the front-to-back direction Da (the longitudinal direction of the elongated hole 53) relative to the top plate 2, the panel device 4 can be effectively prevented from unexpectedly detaching from the top plate 2.

[0066] Furthermore, in the fixture 1 with a top plate of this embodiment, the opening 57 is located away from both ends (first end 531, second end 532) of the elongated hole 53 in the longitudinal direction (linear direction). This ensures that even when the panel device 4 is positioned at a first position P1 where the shaft of the first screw member 55 contacts the first end 531 of the elongated hole 53, and at a second position P2 where the shaft of the first screw member 55 contacts the second end 532 of the elongated hole 53, the panel device 4 is reliably prevented from unexpectedly detaching from the top plate 2. When a user slides the panel device 4 relative to the top plate 2 in the longitudinal direction (linear direction) of the elongated hole 53, the panel device 4 is often positioned at either the first position P1 or the second position P2. For this reason, positioning the opening 57 at the above-mentioned position is particularly effective.

[0067] Furthermore, in the fixture 1 with a top plate of this embodiment, the direction in which the opening 57 extends when viewed from the vertical direction Dv is the same among the multiple mounting plate sections. Therefore, even if the panel device 4 is of a size or weight that requires the user to hold it with both hands, the panel device 4 can be attached to and detached from the top plate 2 more easily and safely.

[0068] Furthermore, in the fixture with a top plate 1 of this embodiment, the difference between the diameter dimension D1 of the first female screw 51 and the width dimension W3 of the elongated hole 53 may be greater than the difference between the diameter dimension D2 of the second female screw 52 and the diameter dimension D4 of the insertion hole 54. In such a configuration, the gap between the shaft of the first screw member 55 and the inner surface of the elongated hole 53 when the first screw member 55 is passed through the elongated hole 53 and screwed into the first female screw 51 is greater than the gap between the shaft of the second screw member 56 and the inner surface of the insertion hole 54 when the second screw member 56 is passed through the insertion hole 54 and screwed into the second female screw 52. Therefore, when the second screw member 56 is passed through the insertion hole 54 and screwed into the second female thread 52, the amount of movement that the panel device 4 can make relative to the top plate 2 can be kept small compared to when the second screw member 56 is removed from the insertion hole 54 and the second female thread 52. In other words, the rattle of the panel device 4 relative to the top plate 2 can be reduced. This improves the overall integrity of the top plate fixture 1, including the top plate 2 and the panel device 4. On the other hand, although the first screw member 55 is passed through the elongated hole 53 and screwed into the first female thread 51, when the second screw member 56 is removed from the insertion hole 54 and the second female thread 52, the panel device 4 can be moved more significantly in the width direction Dw of the elongated hole 53 compared to when the second screw member 56 is passed through the insertion hole 54 and screwed into the second female thread 52. This allows the panel device 4 to slide smoothly relative to the top plate 2.

[0069] Furthermore, in the panel device 4 provided in the fixture with a top plate 1 of this embodiment, the panel 41 is detachably attached to the support portion 42, which includes the mounting plate portion 462. Therefore, by removing the panel 41 from the support portion 42, only the support portion 42 of the panel device 4 can be slid or detached from the top plate 2. Since the size and weight of the support portion 42 are smaller than the size and weight of the panel device 4, which includes the support portion 42 and the panel 41, the user can easily slide or detach a part of the panel device 4 from the top plate 2.

[0070] In the above embodiment, the first upright portion 44 and the second upright portion 45 of the support portion 42 may be integrally formed from, for example, a single member. In this case, the support portion 42 does not need to include the connecting plate portion 461 that functions as a spacer.

[0071] Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above and can be modified as appropriate without departing from the spirit of the invention.

[0072] In the present invention, the mounting plate portion 462 is not limited to being configured as part of the bracket 46 or the support portion 42 including it, but may be provided by at least the panel device 4 (optional element).

[0073] In the present invention, the opening 57 formed in the mounting plate portion 462 and extending from the elongated hole 53 to the outer edge of the mounting plate portion 462 may be located, for example, at the first end 531 or the second end 532 of the elongated hole 53.

[0074] In the present invention, the opening 57 formed in the mounting plate portion 462 and extending from the elongated hole 53 to the outer edge of the mounting plate portion 462 may extend, for example, in the longitudinal direction (linear direction) of the elongated hole 53. In this case, the opening 57 may extend, for example, from the second end 532 of the elongated hole 53 to the tip of the mounting plate portion 462.

[0075] In the present invention, the first threaded member 55, which is passed through the elongated hole 53 and then screwed into the first female thread 51, may be, for example, a stepped thread as shown in Figure 9. The shaft portion 551 of the stepped threaded first threaded member 55 has a base shaft portion 551-1 on which no male thread is formed, and a tip shaft portion 551-2 on which a male thread is formed. The base shaft portion 551-1 and the tip shaft portion 551-2 of the first threaded member 55 are arranged in order from the head 552 side toward the extension direction of the shaft portion 551. The diameter of the base shaft portion 551-1 is larger than the diameter of the tip shaft portion 551-2. Also, the diameter of the base shaft portion 551-1 is less than or equal to the width dimension of the elongated hole 53. Furthermore, the length dimension of the base shaft portion 551-1 in the extension direction of the shaft portion 551 is the same as or slightly smaller than the thickness dimension of the mounting plate portion 462.

[0076] If the first threaded member 55 is a stepped thread as described above, the distance between the lower surface 2b of the top plate 2 and the head 552 of the first threaded member 55 can be made approximately equal to the thickness of the mounting plate 462 simply by screwing the tip shaft portion 551-2 of the first threaded member 55 into the first female thread 51 until the base shaft portion 551-1 abuts against the lower surface 2b of the top plate 2. Therefore, compared to the case where a male thread is formed along the entire shaft portion 551 of the first threaded member 55, the degree to which the first threaded member 55 is screwed into the first female thread 51 can be easily adjusted so that the distance between the lower surface 2b of the top plate 2 and the head 552 of the first threaded member 55 is optimized.

[0077] In the present invention, the panel device 4 should be movably mounted on the top plate 2 such that the gap G between the panel device 4 and a part of the circumferential edge (periphery) of the top plate 2 changes when viewed from at least the vertical direction Dv. For this reason, the panel device 4 may be located on or near the longer side 21A of the top plate 2 that is located in front of the top plate 2, which is rectangular in plan view, or on or near the shorter side 22 of the top plate 2. Furthermore, the plan view shape of the top plate 2 to which the panel device 4 is attached is not limited to a rectangle, but may be any shape such as a circle.

[0078] In the present invention, for example, the first female screw 51 and the second female screw 52 constituting the fixing structure 5 may be formed in the panel device 4 (first component), and the elongated hole 53 and insertion hole 54 constituting the fixing structure 5 may be formed in the top plate 2 (second component).

[0079] In the present invention, the mounting plate portion 462 of the panel device 4 may be arranged, for example, overlapping the upper surface 2a of the top plate 2 in the vertical direction Dv.

[0080] In the present invention, the optional element that is mounted to the top plate 2 so as to be movable in a linear direction along the lower surface 2b, thereby changing the gap G between the top plate 2 and its edges (e.g., long sides 21A, 21B, short side 22) in a plan view from the vertical direction Dv, is not limited to the panel device 4 shown in the above embodiment. The optional element may be, for example, a skirting plate suspended downward from the top plate 2. In this case, the skirting plate may include, for example, a mounting plate portion 462 similar to that in the above embodiment.

[0081] The furniture with a tabletop 1 to which the present invention is applied is not limited to the desk of the above embodiment, but may also be a box or wagon, etc., in which the support structure 3 that supports the tabletop 2 has a storage section for storing articles.
