Description

[Technical Field]

[0001] The present invention relates to a fixture with a top. [Background technology]

[0002] BACKGROUND ART In conference rooms and work spaces in offices, public facilities, schools, residences, and the like, furniture with a top that has a work surface for workers to work on is used (for example, Patent Document 1).

[0003] In recent office environments, it has become increasingly common for workers to flexibly change where they work within the office space by moving furniture with tabletops depending on the work they are doing that day, their mood, or the organization they belong to.

[0004] In response to these changes in the working environment, a new type of furniture with a tabletop has been proposed, with casters on the underside so that workers can move it easily. This type of furniture with a tabletop allows workers to work more freely and efficiently. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-085164 Summary of the Invention [Problem to be solved by the invention]

[0006] When moving a tabletop-equipped fixture, it is necessary to move not only the items used by the worker in their work, but also the worker's luggage, etc. at the same time. For this reason, it is preferable that the tabletop-equipped fixture has an article placement section on which luggage can be placed. However, if an article placement section is provided in the tabletop-equipped fixture, the structure of the tabletop-equipped fixture becomes complicated, which increases the number of steps required to manufacture the tabletop-equipped fixture and increases manufacturing costs.

[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a piece of furniture with a top that has an item placement section on which office workers can place their belongings and that can reduce manufacturing costs. [Means for solving the problem]

[0008] One aspect of the present invention provides a fixture with a top plate comprising a top plate having a work surface, a base supporting the top plate, a flat plate member having an upper surface and a lower surface located opposite the upper surface, casters supporting the lower surface and capable of running on a floor surface, and a support structure supporting the base, wherein on the upper surface, the flat plate member has a central portion supporting the base, and an item placement portion located around the central portion and on which items are placed.

[0009] According to the fixture with a tabletop according to the above aspect, the support structure includes a flat plate member and casters, and the item placement section is located around the center of the flat plate member, so that the worker can move the fixture with the tabletop while placing items, luggage, etc. that the worker will use for work on the item placement section. This increases the worker's work freedom and allows them to work efficiently.

[0010] Furthermore, there is no need to provide a separate item placement section on the tabletop-equipped fixture; the function of the item placement section is given to the flat plate member that forms part of the support structure, so the structure of the tabletop-equipped fixture is simplified, the manufacturing labor required to manufacture the tabletop-equipped fixture does not increase, and manufacturing costs can be reduced.

[0011] In one aspect of the fixture with a tabletop according to the present invention, the edge of the tabletop may be located outside the edge of the flat plate member when viewed in the vertical direction. According to the above-described aspect of the tabletop-equipped fixture, the article placement section does not protrude beyond the edge of the tabletop. Furthermore, when the tabletop-equipped fixture is moved, the article placement section does not come into contact with obstacles present around the tabletop-equipped fixture, ensuring safety when the tabletop-equipped fixture is moved.

[0012] In one aspect of the fixture with a tabletop according to the present invention, the flat plate member may have a shape that follows the shape of the tabletop. Here, "the flat plate member has a shape that imitates the top plate" means, for example, that if the planar shape of the top plate is a polygonal shape with multiple corners, the planar shape of the flat plate member is also a polygonal shape, and the number of corners on the top plate is the same as the number of corners on the flat plate member. As an example, the planar shape of the flat plate member may be similar to the planar shape of the top plate. In such a similarity relationship, it is preferable that the center of gravity of the flat plate member and the center of gravity of the top plate coincide when viewed in the Z direction. As an example, if the sides forming the planar shape of the top plate are curved, the sides forming the planar shape of the flat plate member may also be curved.

[0013] According to the above-described aspect of the tabletop-equipped fixture, the flat plate member has a shape that follows the tabletop, so the item placement section does not protrude beyond the edge of the tabletop. Furthermore, when the tabletop-equipped fixture is moved, the item placement section does not come into contact with obstacles around the tabletop-equipped fixture, ensuring safety during movement. Furthermore, because the flat plate member has a shape that follows the tabletop, the area of ​​the item placement section on the flat plate member can be expanded as much as possible.

[0014] In one embodiment of the present invention, the item mounting section may include a first item mounting section located on both sides of the central portion in a first direction parallel to the flat plate member, and a second item mounting section located on both sides of the central portion in a second direction parallel to the flat plate member and perpendicular to the first direction.

[0015] In one embodiment of the present invention, in a fixture with a top, the first item mounting section has a first width in the first direction from the end of the central portion to the edge of the flat plate member, and the second item mounting section has a second width in the second direction from the end of the central portion to the edge of the flat plate member, and the first width may be different from the second width.

[0016] According to the fixture with a top plate according to the above-described embodiment, the first and second item placement sections can be formed in separate locations on the flat plate member. Furthermore, since the first width is different from the second width, the sizes of the first and second item placement sections can be changed. Therefore, items of various shapes can be placed on the item placement section having the first and second item placement sections, thereby increasing the convenience of the fixture with a top plate.

[0017] In one aspect of the furniture with a top plate according to the present invention, the base may have an item support surface located adjacent to the item placement portion. According to the fixture with a top plate according to the above-described embodiment, when an item is placed on the item placement section, the item contacts the item support surface, thereby maintaining the position of the item. This prevents the item from tipping over on the item placement section. In particular, even if an office worker moves the fixture with a top plate while an item, luggage, or the like is placed on the item placement section, the item support surface prevents the item from tipping over.

[0018] In the fixture with a top plate according to one aspect of the present invention, the article placement section may be covered with a cover member. According to the fixture with a top plate according to the above aspect, when an item is placed on the item placement section, the cover member is positioned between the item placement section and the item, thereby preventing the item from being damaged by friction generated between the item placement section and the item. [Effects of the Invention]

[0019] According to the fixture with a top panel according to this aspect of the present invention, it is possible to provide an article placement section on which an office worker's belongings are placed, and to reduce manufacturing costs. [Brief explanation of the drawings]

[0021] A fixture according to an embodiment of the present invention will be described with reference to the drawings. The fixture according to this embodiment is an example of a fixture with a top. In the following description, components having the same or similar functions are denoted by the same reference numerals. Duplicate descriptions of those components may be omitted. The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the size ratio between parts, etc., may not necessarily be the same as the actual ones.

[0022] In this embodiment, an XYZ Cartesian coordinate system is set up to explain the positional relationship of the fixture configuration. Of the directions perpendicular to the floor surface on which the fixtures are placed, the direction of gravity is referred to as the downward direction (-Z direction), and the direction opposite to the direction of gravity is referred to as the upward direction (+Z direction). When there is no need to distinguish between the downward and upward directions, they are simply referred to as the up-down direction (Z direction).

[0023] Of the two directions perpendicular to the up-down direction, the longitudinal direction of the tabletop is referred to as the left-right direction (Y direction). One of the left-right directions is referred to as the right direction (+Y direction), and the opposite direction is referred to as the left direction (-Y direction). The Y direction is an example of the second direction.

[0024] Of the two directions perpendicular to the up-down direction, the shorter side direction of the tabletop is referred to as the depth direction (X direction). One of the depth directions is referred to as the forward direction (+X direction), and the direction opposite the forward direction is referred to as the rearward direction (-X direction). The X direction is an example of a first direction.

[0025] The terms "X direction" and "Y direction" are used to explain the relative positions of the multiple components that make up the fixtures, and the shape and structure of each of the multiple components, and do not define the layout of the fixtures. The direction parallel to the X and Y directions is sometimes called the "horizontal direction." When the shape viewed in the Z direction is a square, the direction in which one side extends is referred to as the X direction, and the direction perpendicular to the X direction is referred to as the Y direction.

[0026] In this embodiment, ordinal numbers such as "first" and "second" are used to avoid confusion in understanding the components of the fixtures, and do not limit the quantity of the components. In this embodiment, the shape seen from the Z direction may be referred to as the "planar shape."

[0027] The meaning of the term "office worker" used in this embodiment is not limited to a person who uses an electronic device placed on the top of a fixture. In an office space, a person who places items or luggage on the top, base plate, or item tray of a fixture, a person who installs a battery on a fixture, or a person who uses a battery installed on a fixture to charge an electronic device may also be referred to as an office worker. Note that, since an office worker uses the fixture, the office worker may also be referred to as a user.

[0028] <Fixtures> Fig. 1 is a perspective view showing the fixture according to this embodiment. Fig. 2 is an exploded perspective view of the fixture according to this embodiment, showing the components that make up the fixture. Fig. 1 shows a state in which battery B is installed in discharge unit 40. Battery B is not shown in Fig. 2.

[0029] As shown in Figures 1 and 2, the furniture 100 according to this embodiment includes a top plate 10, a support 21, a base plate 22, a power terminal unit 30, a discharge unit 40, wiring 50, casters 60, and an article tray 70. A battery B, which will be described later, is detachable from the discharge unit 40. The support 21 is an example of a base. The base plate 22 is an example of a flat member.

[0030] <Tabletop> The top plate 10 has an upper surface 11 and a lower surface 12 located opposite the upper surface 11. The upper surface 11 is a single plane. The term "single plane" refers to a single plane that does not have any recesses or protrusions such as wiring outlets where power strips for supplying power to electronic devices can be placed. In other words, the upper surface 11 does not have any uneven parts that would interfere with the work of an office worker. The upper surface 11 is a work surface on which an office worker works. In other words, an office worker can operate an electronic device by placing the electronic device on the upper surface 11, which is the work surface.

[0031] The electronic device can obtain the power output by battery B. The electronic device is not particularly limited. Examples of the electronic device include a notebook personal computer, a portable tablet terminal, a smartphone, a wireless communication router, a desk lamp, a desk fan, and a display.

[0032] 1 and 2, the planar shape of the tabletop 10 is, for example, a substantially rectangular shape. The term "substantially rectangular shape" refers to the overall shape of the tabletop when viewed in the Z direction, and does not necessarily mean only a geometrically defined rectangle. The term "substantially" used to describe the shape refers to a shape with chamfered corners, a shape with curved sides extending in the X and Y directions, and a shape that includes manufacturing errors. In the following explanation, the same interpretation applies to the word "abbreviated" which describes the shape of the components that make up the fixtures.

[0033] The tabletop 10 has an edge 10E that protrudes in the X and Y directions. The edge 10E protrudes further in the X and Y directions than the support 21, allowing an office worker to easily grasp the tabletop 10. Therefore, when moving the fixture 100, the worker can grasp the edge 10E to perform the work.

[0034] The planar shape of the tabletop 10 is not limited to a substantially rectangular shape. The planar shape of the tabletop 10 may be, for example, a substantially triangular shape, a substantially square shape, a substantially parallelogram shape, a substantially rhombus shape, a polygonal shape with five or more corners, a substantially circular shape, a substantially elliptical shape, or a substantially oval shape. The shape of the tabletop provided on known fixtures used in general office spaces may be applied to the tabletop 10, or the shape of the tabletop provided on known tables used in entertainment facilities, eating and drinking establishments, etc. The material of the tabletop 10 is not particularly limited, and known materials may be used.

[0035] The size of the top plate 10, that is, the area of ​​the upper surface 11, can be changed as appropriate according to the design. The height of the fixture 100, that is, the height from the floor surface FL to the upper surface 11, can be changed as appropriate depending on the design. In the case of the fixture 100 shown in Fig. 1, the height is set to, for example, 720 mm.

[0036] <Strut> The support pillar 21 is a member that supports the top plate 10. The support pillar 21 has a top plate connection portion 23, a first extension portion 24A, a second extension portion 24B, a battery accommodating portion 25A, a unit accommodating portion 25B, and a plate connection portion 26. A first cover member 27, a second cover member 28, and a base plate 22, which will be described later, are connected to the support pillar 21.

[0037] As shown in FIG. 2, the top plate 10, the support column 21, the base plate 22, the first cover member 27, the second cover member 28, the discharge unit 40, and the article tray 70 are separable from one another.

[0038] Regarding the shape of the support pillars 21, in a cross section parallel to the X and Y directions, the support pillars 21 have a substantially rectangular outer shape (outline). The outline of the support pillars 21 has a shape in which the support pillars 21 gradually become thinner in the +Z direction upward from the floor surface FL. The shape of the support pillars 21 is not limited to the shapes shown in FIGS. 1 and 2. The support pillars 21 may have a shape in which the outline of the support pillars 21 does not change in the Z direction, that is, a shape in which the support pillars 21 extend straight from the base plate 22 toward the tabletop 10 without inclining. When viewed in the X direction, the support pillars 21 have a substantially trapezoidal shape.

[0039] The material of the support 21 is determined appropriately in consideration of the strength and weight of the fixture 100. The support 21 may be made of a resin material or a metal material. The support pillar 21 may have an adjustment mechanism for adjusting the height from the floor surface FL to the top board 10. In this case, the adjustment mechanism includes, for example, a gas spring.

[0040] <Top board connection part> The top plate connection portion 23 has an upper end portion 23A. The upper end portion 23A is connected to the lower surface 12. In this embodiment, an article tray 70 is disposed between the upper end portion 23A and the lower surface 12, and the upper end portion 23A and the lower surface 12 are indirectly connected via a part of the article tray 70. The upper end portion 23A and the lower surface 12 may also be directly connected. The connection structure connecting the lower surface 12 and the top plate connection portion 23 is not particularly limited. The lower surface 12 and the top plate connection portion 23 may be fixed using known fixing members such as screws, or the lower surface 12 and the top plate connection portion 23 may be fixed by adhesive.

[0041] A power supply terminal section 30 is provided inside the top panel connection section 23. In the Z direction, the power supply terminal unit 30 is disposed between the article tray 70 and the top panel 10. The top panel connection unit 23 has a support column opening 23B formed in the surface of the support column 21. The support column opening 23B is formed on the surface of the support column 21 facing the +X direction and the surface facing the -X direction. The support column opening 23B exposes a plug insertion port 31 of the power supply terminal unit 30 (described later) to the outside of the support column 21. In other words, the top panel connection unit 23 exposes the two power supply terminal units 30 to the outside of the support column 21.

[0042] The pillar opening 23B may be formed on a surface of the pillar 21 facing the +Y direction or on a surface facing the -Y direction. In this case, the power supply terminal portion 30 can be exposed to the outside of the pillar 21 in the +Y direction or the -Y direction.

[0043] <First extension part, second extension part> The first extension portion 24A and the second extension portion 24B are aligned in the Y direction. The end of the first extension portion 24A and the end of the second extension portion 24B in the +Z direction are connected to the top panel connection portion 23. The end of the first extension portion 24A and the end of the second extension portion 24B in the -Z direction are connected to the plate connection portion 26. The first extension portion 24A and the second extension portion 24B extend from the plate connection portion 26 toward the top panel connection portion 23 so as to be inclined with respect to the Z direction.

[0044] <Battery compartment> Battery storage section 25A is provided inside support pillar 21. In other words, the phrase "inside support pillar 21" means that battery storage section 25A is formed at a position inside contour 21E that forms the outer shape of support pillar 21 in a projection view of fixture 100 seen in the -Z direction. The battery storage section 25A can store the battery B. In other words, the battery B can be stored in the space inside the battery storage section 25A. The battery B can be attached to and detached from the discharge section 40 in the battery storage section 25A.

[0045] <Unit storage area> The unit accommodating section 25B is provided inside the support 21. In the Z direction, the unit accommodating section 25B is located below the battery accommodating section 25A. The unit accommodating section 25B can accommodate the discharge section 40. In other words, the discharge section 40 can be accommodated in the space inside the unit accommodating section 25B. The battery accommodating section 25A and the unit accommodating section 25B may be simply referred to as the accommodating section 25.

[0046] In the Z direction, the battery storage section 25A is located between the top board connection section 23 and the base plate 22. In other words, in the Z direction, the battery storage section 25A is located between the top board connection section 23 and the plate connection section 26. In the Y direction, the battery accommodating portion 25A is located between the first extending portion 24A and the second extending portion 24B. When viewed in the X direction, the battery storage section 25A is surrounded by the top panel connection section 23, the first extension section 24A, the second extension section 24B, and the plate connection section 26, and has a substantially O-shape. In other words, when viewed in the X direction, the through-space that passes through the support column 21 is the battery storage section 25A.

[0047] The worker can visually check the battery storage section 25A and can confirm whether or not the battery B is stored in the battery storage section 25A. The worker can reach out his or her fingers to the battery storage section 25A and remove the battery B stored in the battery storage section 25A from the battery storage section 25A or store the battery B in the battery storage section 25A.

[0048] When viewed in the -Z direction, the unit accommodating portion 25B is a space formed inside the plate connecting portion 26. The discharge portion 40 is disposed in the unit accommodating portion 25B.

[0049] <Plate connection part> The plate connecting portion 26 has two wall portions 26X extending in the X direction and two wall portions 26Y extending in the Y direction. The plate connecting portion 26 forms an internal space surrounded by the walls 26X and 26Y. This internal space is the unit accommodating portion 25B.

[0050] <First cover member, second cover member> The first cover member 27 and the second cover member 28 are, for example, low-friction members, and may be made of, for example, felt fabric. When viewed in the X direction, the first cover member 27 has a shape that corresponds to the outer shape of the battery accommodating section 25A. By inserting the first cover member 27 into the battery accommodating section 25A in the X direction, the first cover member 27 is fixed to the inside of the support column 21.

[0051] The first cover member 27 has two extending cover portions 27A extending in the Y direction. A cover opening 27B is formed inside the extending cover portions 27A and positioned below the first cover member 27. The cover opening 27B is a portion that exposes the mounting surface 44b of the discharger 40. Specifically, the cover opening 27B exposes the mounting surface 44b to the battery housing portion 25A.

[0052] When the discharge portion 40 is disposed inside the plate connection portion 26, the two extending cover portions 27A hide the gap between the discharge portion 40 and the plate connection portion 26 in the X direction, thereby improving the design of the battery storage portion 25A. The cover opening 27B formed in the first cover member 27 prevents the entire discharge unit 40 from being exposed to the battery storage section 25A, while realizing electrical connection between the battery B and the discharge unit 40.

[0053] The second cover member 28 has a ring shape. The outer contour of the ring shape corresponds to the base plate 22. The inner contour of the ring shape corresponds to the outer shape of the support column 21. The second cover member 28 is disposed on and fixed to the base plate 22.

[0054] <Support structure> The base plate 22 and the casters 60 form a support structure. The base plate 22 and the casters 60 support the support column 21 .

[0055] <Base plate> The base plate 22 is located on the opposite side of the support column 21 from the top plate connection portion 23 in the Z direction. The base plate 22 is a plate-like member connected to the plate connection portion 26. In the example shown in FIGS. 1 and 2, the base plate 22 is parallel to the X and Y directions.

[0056] There are no particular limitations on the connection structure that connects the base plate 22 and the plate connection portion 26. The base plate 22 and the plate connection portion 26 may be fixed using a known fixing member such as a screw, or the base plate 22 and the plate connection portion 26 may be fixed by adhesive. The material of the base plate 22 is appropriately determined in consideration of the strength and weight of the fixture 100. For example, the base plate 22 may be made of a resin material or a metal material.

[0057] The base plate 22 has a plate upper surface 22A, a plate lower surface 22B, and a plate flange 22F. The plate upper surface 22A is an example of an upper surface. The plate lower surface 22B is an example of a lower surface. The plate flange 22F is an example of an edge portion of a flat plate member. The plate upper surface 22A is a surface on which the second cover member 28 is placed. The plate upper surface 22A supports the discharge unit 40 arranged inside the plate connection unit 26. The plate lower surface 22B is connected to the casters 60. In this embodiment, four casters 60 are connected to the plate lower surface 22B.

[0058] The plate flange 22F is a protrusion that protrudes in the +Z direction from the plate upper surface 22A. The plate flange 22F is provided on the outer peripheral edge of the base plate 22 and is formed so as to surround the outer periphery of the base plate 22 in the X and Y directions. The plate flange 22F is a portion that prevents an item of luggage from falling outward from the base plate 22 when the item of luggage is placed on the base plate 22.

[0059] When viewed in the Z direction, the edge 10E of the top plate 10 is located outside the plate flange 22F. In other words, the size of the base plate 22 is smaller than the size of the top plate 10, and the plate flange 22F is located inside the area surrounded by the edge 10E when viewed in the Z direction.

[0060] The planar shape of the base plate 22 follows the planar shape of the top plate 10. 1 and 2, the shape of the base plate 22 follows the shape of the tabletop 10 and is substantially rectangular. The shape of the base plate 22 is selected appropriately depending on the shape of the tabletop 10. Specifically, the planar shape of the base plate 22 may be, for example, a substantially triangle, a substantially square, a substantially parallelogram, a substantially rhombus, a polygon with five or more corners, a substantially circle, a substantially ellipse, or a substantially oval. The shape of the base plate 22 is not limited as long as a shape that follows the planar shape of the tabletop 10 is adopted and the position of the fixture 100 can be stabilized.

[0061] On plate upper surface 22A, base plate 22 has central portion 22C that supports support column 21, and article placement portion 22D located around central portion 22C. Article placement portion 22D is a portion on which an article is placed.

[0062] <Central part> A discharge part 40 is disposed on the central part 22C and is located inside the plate connection part 26. The shape of the central part 22C when viewed in the Z direction, that is, the planar shape of the central part 22C, is the same as that of the plate connection part 26. In other words, the area between the central portion 22C and the plate flange 22F is the article placement portion 22D. When viewed in the -Z direction, the article placement portion 22D has a ring shape, that is, a substantially O-shape.

[0063] <Item placement section> The article placement section 22D has a first article placement section 22E and a second article placement section 22S. The first article placement sections 22E are located on both sides of the central section 22C in the X direction. That is, two first article placement sections 22E are provided on the plate upper surface 22A. The second article placement sections 22S are located on both sides of the central section 22C in the Y direction. That is, two second article placement sections 22S are provided on the plate upper surface 22A. In other words, the two first article placement sections 22E and two second article placement sections 22S are provided on the plate upper surface 22A so as to surround the central section 22C.

[0064] The first article placement section 22E has a first width W1 in the X direction from the end 22XE of the central section 22C to the plate flange 22F. The second article placement section 22S has a second width W2 in the Y direction from the end 22YE of the central section 22C to the plate flange 22F. The first width W1 is different from the second width W2. In this embodiment, the second width W2 is larger than the first width W1. Note that if the shape of the base plate 22 is approximately square, the first width W1 and the second width W2 may be the same.

[0065] The symbol GP in FIG. 1 indicates the position of the center of gravity of the fixture 100. The symbol LY is an imaginary line that is parallel to the Y direction and passes through the center of gravity GP. The symbol LX is an imaginary line that is parallel to the X direction and passes through the center of gravity GP. The two first item placement sections 22E are symmetrical with respect to the imaginary line LY. The two second item placement sections 22S are symmetrical with respect to the imaginary line LX. The item placement section 22D is covered with a second cover member 28 made of felt fabric.

[0066] The angle between the wall 26X of the plate connecting portion 26 and the second article placement portion 22S is approximately a right angle. The wall 26X extends from the plate upper surface 22A toward the top board 10. Therefore, when an item is placed on the second article placement portion 22S, the item comes into contact with the wall 26X, thereby maintaining the position of the item. In other words, the wall 26X is an example of an article support surface located adjacent to the second article placement portion 22S. The article support surface may be a curved surface.

[0067] The angle between wall portion 26Y of plate connecting portion 26 and first article placement portion 22E is approximately a right angle. Wall portion 26Y extends from plate upper surface 22A toward top board 10. Therefore, when an item is placed on first article placement portion 22E, the item comes into contact with wall portion 26Y, thereby maintaining the position of the item. In other words, wall portion 26Y is an example of an item support surface located adjacent to first article placement portion 22E.

[0068] <Caster> The caster 60 has a rotatable roller that comes into contact with the floor surface FL. The caster 60 is capable of running on the floor surface FL while supporting the plate underside 22B. The caster 60 supports the fixture 100 while allowing the fixture 100 to move in the X and Y directions. The caster 60 is, for example, a commercially available known caster part.

[0069] The casters 60 may have a known locking mechanism that stops the rotation of the casters 60. Since the fixture 100 is equipped with the casters 60, the fixture 100 can be freely moved on the floor surface FL. In the example shown in FIG. 2, the number of casters 60 is four. The number of casters 60 can be changed as appropriate, and there is no limit to the number of casters 60 as long as it is three or more.

[0070] <Item tray> The article tray 70 is fixed to the top panel connection portion 23. The article tray 70 is fixed to the support column 21 so as to surround the periphery of the support column 21. When viewed in the -Z direction, the article tray 70 is located inside the area surrounded by the edge portion 10E of the top panel 10.

[0071] The article tray 70 can hold the worker's luggage and small items. For this reason, the article tray 70 may also be referred to as an article placement section. Examples of the worker's luggage and small items that can be placed on the article tray 70 include smartphones, handbags, handkerchiefs, cosmetics, newspapers, books, etc. There are no restrictions on the type of luggage or small items as long as they are items that the worker carries.

[0072] The article tray 70 is located below the lower surface 12 of the top panel 10. In other words, the article tray 70 is located between the lower surface 12 and the battery housing section 25A. The article tray 70 is located on the opposite side of the support column 21 from the base plate 22 in the Z direction.

[0073] The article tray 70 has a plate member 71, a protrusion 72 protruding from the plate member 71 in the +Z direction, and a tray opening 73 formed on the surface of the protrusion 72. A space is formed inside the protrusion 72. In other words, the article tray 70 has a recess 74 having a shape corresponding to the shape of the protrusion 72. This is a portion formed in the plate member 71 so as to be recessed in the +Z direction. The upper end 23A of the top panel connection portion 23 is inserted into the recess 74. With the upper end 23A inserted into the recess 74, the article tray 70 is fixed to the support 21.

[0074] When the article tray 70 is fixed to the support column 21, the tray opening 73 coincides with the position of the support column opening 23B. As a result, the power supply terminal portion 30 is exposed to the outside through the tray opening 73 and the support column opening 23B. The tray opening 73 and the support column opening 23B are located between the lower surface 12 of the top panel 10 and the article tray 70. In other words, the power supply terminal portion 30 is located between the lower surface 12 of the top panel 10 and the article tray 70.

[0075] In this embodiment, the article tray 70 is fixed to the support 21 by inserting the upper end 23A into the recess 74, but the connection structure connecting the article tray 70 and the support 21 is not particularly limited. The article tray 70 and the support 21 may be fixed using a known fixing member such as a screw, or the article tray 70 and the support 21 may be fixed by adhesive.

[0076] The plate member 71 of the article tray 70 has a tray upper surface 71A and a tray flange 70F. The tray upper surface 71A can accommodate not only the worker's articles but also the excess portion of the power cable connected to an electronic device.

[0077] The tray flange 70F is located on the edge of the article tray 70. The tray flange 70F is a protrusion that protrudes in the +Z direction from the tray upper surface 71A. The tray flange 70F is provided on the outer periphery of the article tray 70, and is formed so as to surround the outer periphery of the article tray 70 in the X and Y directions. The tray flange 70F is a portion that prevents an article from falling outward from the article tray 70 when the article is placed on the article tray 70.

[0078] In the X and Y directions, the tray flange 70F does not protrude outside the edge 10E of the top plate 10. In other words, when viewed in the -Z direction, the tray flange 70F is located inside the area surrounded by the edge 10E of the top plate 10. In other words, in the horizontal direction, the edge 10E of the top plate 10 is located outside the tray flange 70F located at the edge of the article tray 70.

[0079] The material of the article tray 70 is determined appropriately in consideration of the weight of the articles to be placed on the article tray 70. For example, the article tray 70 may be made of a resin material or a metal material. 1 and 2, the planar shape of the article tray 70 is substantially rectangular. The planar shape of the article tray 70 can be changed in consideration of the manner in which the fixture 100 is used and the shape of the articles to be placed on the article tray 70.

[0080] <Modification of the article tray> The article tray 70 shown in FIG. 2 includes a protrusion 72 having a tray opening 73, but the shape of the article tray 70 is not limited to the shape shown in FIG. The article tray 70 may have a through hole instead of the protrusion 72. In this case, the through hole has a shape corresponding to the planar shape of the top panel connection part 23, and is formed in the central region of the plate member 71. The position of the through hole in the X direction and the Y direction is the same as that of the protrusion 72.

[0081] In this configuration, the article tray 70 and the top plate connection part 23 are fixed with the top plate connection part 23 inserted into the through hole. In other words, the top plate connection part 23 is fitted into the through hole. The connection structure of the top plate connection part 23 to the through hole is not particularly limited. The article tray 70 and the support 21 may be fixed by adhesive. A flange extending in the Z direction from the periphery of the through hole may be provided, and the flange and the top plate connection part 23 may be fixed using a known fixing member such as a screw. In the structure of this modified example, it is possible to connect the upper end part 23A and the underside 12 of the top plate 10 without using the article tray 70.

[0082] In this modification, the item tray 70 does not have a protrusion 72 with a tray opening 73. Therefore, when the item tray 70 is fixed to the support 21, the power terminal portion 30 is exposed to the outside through the support opening 23B. The support opening 23B is located between the lower surface 12 of the top plate 10 and the item tray 70. In other words, the power terminal portion 30 is located between the lower surface 12 of the top plate 10 and the item tray 70.

[0083] <Discharge section, wiring, power terminal section, battery> FIG. 3A is a perspective view showing the battery B, discharge unit 40, and wiring 50 in the fixture 100 according to this embodiment. FIG. 3B is a perspective view showing the wiring 50 and power terminal unit 30 in the fixture 100 according to this embodiment. FIG. 4 is a block diagram schematically showing the electrical connection relationship between the power terminal unit 30, battery B, discharge unit 40, wiring 50, and electronic devices in the fixture 100 according to this embodiment. The support pole 21 described above is not shown in FIGS. 3A, 3B, and 4. FIG. 3A shows the positional relationship between the cover opening 27B, which exposes the mounting surface 44b, and the discharge unit 40. FIG. 3B shows only one of the two power terminal units 30. FIG. 3B shows the positional relationship between the support pole opening 23B, which exposes the plug insertion port 31, and the power terminal unit 30.

[0084] <Discharge section> The discharge unit 40 is a unit to which the battery B can be attached. The discharge unit 40 converts DC power output from the battery B into AC power and supplies the power to the power supply terminal unit 30 via wiring 50. The discharge unit 40 includes a case 44a, a mounting surface 44b, and an inverter 44c. The discharge unit 40 receives the power output from the battery B. For this reason, the discharge unit 40 may also be referred to as a power receiving unit.

[0085] The case 44a is a container that supports the mounting surface 44b and the inverter 44c. The case 44a is mounted on the base plate 22 inside the plate connecting portion 26. The case 44a may be fixed to the base plate 22 with adhesive, screws, or the like, but may also be mounted on the base plate 22 in an unfixed state.

[0086] The case 44a has an open end that is opened when the mounting surface 44b is removed. The open end faces upward and is closed by the mounting surface 44b when the mounting surface 44b is attached to the case 44a from above. The case 44a also houses an inverter 44c inside. When viewed in the -Z direction, the case 44a has substantially the same shape as the opening shape of the cover opening 27B.

[0087] The inverter 44c is a converter that converts DC power output from the battery B into AC power. As shown in FIG.

[0088] The mounting surface 44b has mounting recesses 44b1 that allow the battery B to be detachably attached in the Z direction. In this embodiment, the number of mounting recesses 44b1 is two. The number of mounting recesses 44b1 may be one, or three or more. Since the mounting surface 44b has two mounting recesses 44b1, multiple batteries B can be attached to the discharge unit 40.

[0089] In this configuration, the worker can visually determine whether or not the battery B is attached to the attachment recess 44b1. The worker can install the battery B in the attachment recess 44b1 and remove the battery B from the attachment recess 44b1. In other words, the worker can easily replace the battery B.

[0090] The mounting surface 44b has a flange 44F. The size of the flange 44F is larger than that of the case 44a in the X and Y directions. That is, when the case 44a is inserted into the cover opening 27B, the flange 44F is not inserted into the cover opening 27B. When viewed in the -Z direction, the flange 44F hides the gap between the case 44a and the cover opening 27B.

[0091] The mounting recess 44b1 is, for example, circular in shape. The diameter of the mounting recess 44b1 is larger than the diameter of the lower part of the battery B and can accommodate the lower part of the battery B. The mounting recess 44b1 is provided with terminals. The terminals of the mounting recess 44b1 can be connected to the negative and positive terminals provided on the bottom of the battery B when the battery B is attached to the mounting recess 44b1. The shape of the mounting recess 44b1 is not limited to a circle, and a shape other than a circle may be adopted for the mounting recess 44b1.

[0092] <Wiring> The wiring 50 is a member that electrically connects the power supply terminal unit 30 and the battery B (discharge unit 40). Specifically, one end of the wiring 50 is connected to the power supply terminal unit 30. The other end of the wiring 50 is electrically connected to the discharge unit 40. In other words, the wiring 50 can be electrically connected to the battery B.

[0093] When battery B is accommodated in battery accommodating section 25A and battery B is placed on discharge section 40, an electric current flows between inverter 44c of discharge section 40 and battery B. In this state, wiring 50 electrically connects power supply terminal section 30 and battery B, and supplies power from battery B to power supply terminal section 30.

[0094] The wiring 50 is arranged inside the support pillar 21. In other words, the wiring 50 is arranged inside the plate connection portion 26, the second extension portion 24B, and the top plate connection portion 23 that constitute the support pillar 21. The wiring 50 extends approximately in the Z direction inside the support pillar 21. A guide portion that regulates the extension direction of the wiring 50 may be arranged inside the support pillar 21.

[0095] <Power terminal section> The power terminal unit 30 is a component to which a power cable connected to an electronic device of an office worker is connected. As shown in Figures 1 and 2, the power terminal unit 30 is disposed between the underside 12 of the tabletop 10 and the article tray 70 in the Z direction. The power terminal unit 30 is disposed inside the tabletop connection unit 23 that constitutes part of the support column 21.

[0096] As shown in Fig. 4, there are two power terminal units 30. As shown in Fig. 3B, one power terminal unit 30 has two plug insertion ports 31. The plug insertion ports 31 are connected to wiring 50. The power terminal unit 30 can be called, for example, a power tap, a terminal mounting portion, or a socket. The power terminal unit 30 is disposed on the top panel connection portion 23, which is part of the support column 21.

[0097] The plug insertion port 31 can output power converted from DC power to AC power by the inverter 44c to the electronic device. In other words, the plug insertion port 31 of the power terminal unit 30 can extract AC power similar to that from a general commercial power source. When the plug P of the power cable of the electronic device is connected to the plug insertion port 31 of the power terminal unit 30, the power terminal unit 30 can supply power from the battery B to the electronic device through the wiring 50.

[0098] In this embodiment, there are two power supply terminal portions 30. One power supply terminal portion 30 is exposed to the outside of the support column 21 through the support column opening 23B in the +X direction. The other power supply terminal portion 30 is exposed to the outside of the support column 21 through the support column opening 23B in the -X direction.

[0099] The power supply terminal unit 30 may include, for example, a USB (Universal Serial Bus) outlet tap. The USB outlet tap converts AC power into DC power and supplies power to a mobile device such as a tablet terminal or smartphone connected to the USB outlet tap. The power supply terminal unit 30 may also have a switch that switches the electrical connection between the power supply terminal unit 30 and the discharge unit 40. Furthermore, the power supply terminal unit 30 may include a wireless LAN terminal or a LAN (Local Area Network) cable connector. The power supply terminal unit 30 may be a contactless power supply device.

[0100] <Modifications of the power supply terminal portion and the discharge portion> The power supply terminal unit 30 may include a female terminal (female connector) of a USB terminal. In this case, the discharge unit 40 may supply DC power supplied from the battery B directly to the USB terminal without going through the inverter 44c. This makes it possible to supply DC power to an electronic device that includes a male terminal (male connector) of a USB terminal that is connected to the female terminal of the USB terminal. USB terminal standards include, for example, USB Type-A, USB Type-B, and USB Type-C.

[0101] According to this modification, power conversion by the inverter 44c is not required, i.e., there is no need to convert DC power to AC power, and there is also no need to convert AC power to DC power, so that an efficient power supply can be achieved.

[0102] The discharge unit may also include both a first power supply system that uses the inverter 44c and a second power supply system that does not use the inverter 44c. In this case, the first power supply system has the electrical connection structure shown in FIG. 4. The second power supply system has an electrical connection structure that includes a battery B placed on the placement surface 44B of the placement tray, a power supply terminal unit 30 that has a female USB terminal, and wiring that connects the battery B and the power supply terminal unit 30. The second power supply system may also include a control circuit. The control circuit of the second power supply system may, for example, control the DC voltage output from the power supply terminal unit 30 to be constant.

[0103] <Battery> Battery B is a portable power storage device that can be charged and discharged, in other words, a rechargeable portable battery. Battery B has a prismatic main body B1, a handle B2 provided on the top of main body B1, and a display B3 provided on the side of main body B1.

[0104] The handle B2 extends in the +Z direction and has a curved shape. An office worker can lift the battery B by grasping the upper part of the handle B2. The shape of the handle B2 is not limited to the shape shown in FIG. 3A, but it is preferable that the handle B2 has a shape that allows it to be lifted with one hand.

[0105] The main body B1 of battery B contains a rechargeable lithium battery or the like. The bottom surface of the main body B1 of battery B is provided with a negative terminal and a positive terminal connected to the lithium battery. The negative and positive terminals of the main body B1 can be connected to the terminals of the mounting recess 44b1.

[0106] Display unit B3 displays the remaining charge amount of battery B. The worker can visually check the information displayed on display unit B3 and determine whether or not to replace battery B. Display unit B3 is, for example, a liquid crystal display device.

[0107] In this embodiment, the number of batteries is two. The number of batteries is not limited. The number of batteries may be one, or three or more. When the number of batteries is two or more, even if one battery has no charge, the electronic device can continue to be charged as long as the other battery has sufficient charge. In other words, a battery backup function can be realized.

[0108] <Batteries, power terminals, discharge parts, wiring, and electrical connections for electronic devices> As shown in FIG. 4, in the discharge unit 40, the mounting surface 44b having the mounting recess 44b1 is electrically connected to the inverter 44c. 4, the discharge unit 40 may include a control device. For example, when a plurality of batteries B are attached to the discharge unit 40, the control device may select a battery B that will consume power.

[0109] Each of the two power supply terminal units 30 is connected to the discharge unit 40 via wiring 50. In other words, in the fixture 100, two power supply terminal units 30 are connected to the discharge unit 40. Power can be supplied from a single discharge unit 40 to multiple power supply terminal units 30.

[0110] In this embodiment, the number of wires 50 is two. One wire 50 connects the discharge unit 40 to one of the power supply terminal units 30. The other wire 50 connects the discharge unit 40 to the other power supply terminal unit 30. These wires 50 are housed inside the support 21, and therefore the wires 50 cannot be seen from outside the fixture 100.

[0111] Each of the wires 50 electrically connects the inverter 44c of the discharge unit 40 to the plug insertion port 31 of the power supply terminal unit 30. Specifically, one end of the wire 50 is connected to the plug insertion port 31. The other end of the wire 50 is connected to the inverter 44c. Each of the wires 50 conducts AC power output from the inverter 44c to the plug insertion port 31.

[0112] In this configuration, the battery B is attached to the mounting recess 44b1 of the discharger 40, and the plug P of the electronic device D is inserted into the plug insertion port 31 of the power supply terminal unit 30. The discharger 40 converts DC power output from the battery B into AC power using the inverter 44c. The AC power generated by the inverter 44c is supplied to the power supply terminal unit 30 via the wiring 50, and then supplied to the electronic device D from the plug insertion port 31 of the power supply terminal unit 30.

[0113] When replacing the battery B, the worker removes the battery B, which was previously attached to the discharge unit 40, from the discharge unit 40 by lifting it up from the attachment recess 44b1. Then, the worker attaches a new battery B to the attachment recess 44b1 from above.

[0114] <Center of gravity of fixtures> The fixture 100 has a shape that is line-symmetrical with respect to the imaginary line LY, and also has a shape that is line-symmetrical with respect to the imaginary line LX. When viewed in the Z direction, the position of the center of gravity of the tabletop 10, the position of the center of gravity of the support column 21, and the position of the center of gravity of the battery B coincide with the center of gravity GP. The fixtures according to the modified examples described below may have a shape that is line-symmetrical with respect to at least one of the imaginary lines LY and LX.

[0115] <Action and effect> According to the fixture 100 of this embodiment, the battery storage section 25A capable of storing the battery B is disposed inside the support pole 21, thereby minimizing the space required for installing the battery B in the fixture 100. Furthermore, because the battery storage section 25A is disposed inside the support pole 21, the position of the center of gravity of the fixture 100 can be made more stable than in a structure in which the battery storage section 25A that stores the battery B is provided outside the support pole 21.

[0116] Specifically, in a structure where the battery housing is located outside the base, the center of gravity of the battery and the center of gravity of the fixture are misaligned, making the fixture unstable and difficult to move smoothly.

[0117] In contrast, with the structure of fixture 100 in which battery storage section 25A is disposed inside support column 21, when battery B is stored in battery storage section 25A, the position of the center of gravity of battery B and the position of the center of gravity of fixture 100 are less likely to shift from each other. This makes it possible to stabilize the position of the center of gravity of fixture 100. Therefore, when fixture 100 is moved, fixture 100 is less likely to tip over, and fixture 100 can be moved smoothly.

[0118] Furthermore, the fixture 100 according to this embodiment includes a power terminal unit 30 arranged on the support pillar 21, wiring 50 that electrically connects the power terminal unit 30 and the battery storage unit 25A, and casters 60 connected to the support pillar 21. This eliminates the need to connect the fixture 100 to an outlet provided on the wall or floor that forms the office space.

[0119] Therefore, an office worker using the fixture 100 can freely move the fixture 100 to a position and use the fixture 100. Since the position in the office space where the fixture 100 can be used is not limited, the convenience of the fixture 100 can be improved.

[0120] In the Z direction, the position of the center of gravity of the tabletop 10, the position of the center of gravity of the support 21, and the position of the center of gravity of the battery B are all aligned, so when the battery B is stored in the battery storage section 25A, the position of the center of gravity of the fixture 100 will not shift due to the weight of the battery B. This makes it possible to stabilize the position of the center of gravity of the fixture 100. Therefore, when the fixture 100 is moved, the fixture 100 is less likely to tip over, and the fixture 100 can be moved smoothly.

[0121] The wiring 50 is arranged inside the support 21. Therefore, the wiring 50 is not exposed to the outside of the support 21. In other words, the wiring 50 can be hidden by the support 21. Therefore, it is possible to prevent a decrease in design due to the wiring 50 being exposed to the outside of the support 21, and in other words, it is possible to provide fixture 100 with excellent design.

[0122] The power terminal unit 30 is disposed on the support 21. In other words, the power terminal unit 30 is not disposed on the top plate 10. Therefore, the power terminal unit 30 is not visually noticeable. Therefore, it is possible to provide a fixture 100 with excellent design.

[0123] Because the power supply terminal unit 30 is disposed between the article tray 70 and the top plate 10, there is no need to form a recess or protrusion on the top surface of the top plate 10, such as a wiring outlet, where the power supply terminal unit 30 can be disposed. Therefore, the top surface 11 of the top plate 10, which is the work surface, does not become narrower, and a work surface with a large area can be secured, thereby improving the convenience of the fixture 100.

[0124] Furthermore, the top surface 11 of the tabletop 10 is a single plane, which allows a wide work surface to be secured, thereby increasing the convenience of the furniture 100. The single plane of top surface 11 does not have any recesses or protrusions such as wiring outlets. Therefore, for example, a container filled with liquid such as a beverage will not get caught on a recess or protrusion, causing the liquid to spill onto top surface 11. Therefore, the liquid will not spread across top surface 11. Furthermore, in such cases, the liquid will not come into contact with an electronic device placed on top surface 11, preventing the electronic device from breaking down.

[0125] The article tray 70 is located below the underside 12 of the tabletop 10 and is supported by the support pillars 21. This allows an office worker to place articles on the article tray 70. Furthermore, the furniture 100 can be moved with articles placed on the article tray 70. This improves the ease of use of the furniture 100.

[0126] In the horizontal direction, the edge 10E of the top plate 10 is located outside the tray flange 70F. Therefore, for example, when a container containing a liquid such as a beverage is placed on the top plate 10, even if an employee's fingers or arms accidentally come into contact with the container and the liquid spills from the container, the liquid will not reach the item tray 70. Therefore, items placed on the item tray 70 will not get wet with the liquid. Furthermore, if the item placed on the item tray 70 is an electronic device, the electronic device will not come into contact with the liquid, preventing the electronic device from breaking down.

[0127] The power terminal section 30 is disposed between the underside 12 of the tabletop 10 and the item tray 70. Therefore, when an office worker uses an electronic device, the plug P of the power cable of the electronic device can be electrically connected to the power terminal section 30. Furthermore, the excess portion of the power cable can be placed on the item tray 70. This improves the ease of use of the fixture 100.

[0128] Furthermore, the battery is hidden when viewed in the Y direction, so that the design of the fixture 100 can be improved when viewed from the Y direction. In addition, the worker can insert his or her fingers into the battery storage section 25A from both the +X direction and the -X direction. This allows the worker to grasp the battery B from both the +X direction and the -X direction and remove the battery B from the discharge section 40. In addition, the worker can install the battery B in the discharge section 40 from both the +X direction and the -X direction.

[0129] Casters 60 are arranged on the underside 22B of the base plate 22, so that the worker can move the fixture 100 by holding the tabletop 10 with their fingers and pushing or pulling it horizontally. The worker does not necessarily have to hold the tabletop with their fingers. The fixture 100 can be moved by simply pushing the tabletop horizontally. In particular, the positions of the centers of gravity of the tabletop 10, the support 21, and the battery B all coincide with the center of gravity GP, stabilizing the position of the center of gravity of the fixture 100. This makes it less likely for the fixture 100 to tip over when moved.

[0130] On plate upper surface 22A, article placement section 22D is located around center section 22C of base plate 22, so the worker can move fixture 100 while placing items, luggage, etc. that the worker uses for work on article placement section 22D. This increases the worker's freedom of work and enables the worker to work efficiently.

[0131] In this embodiment, there is no need to provide a separate article placement section 22D on the fixture 100. Because the base plate 22 has the function of the article placement section 22D, the structure of the fixture 100 is simplified. Therefore, the number of steps required to manufacture the fixture 100 does not increase, and manufacturing costs can be reduced.

[0132] In the horizontal direction, edge 10E of top plate 10 is located outside tray flange 70F, so when fixture 100 is moved, article placement section 22D does not come into contact with obstacles present around fixture 100. Therefore, safety can be ensured when fixture 100 is moved.

[0133] Furthermore, even if a container filled with a liquid such as a beverage is placed on the top panel 10 and an employee accidentally touches the container with their fingers or arm, causing the liquid to spill from the container, the liquid will not reach the article placement section 22D. Therefore, the article placed on the article placement section 22D will not get wet with the liquid. Furthermore, if the article placed on the article placement section 22D is an electronic device, the electronic device will not come into contact with the liquid, preventing the electronic device from breaking down.

[0134] Because base plate 22 has a shape that follows the shape of tabletop 10, article placement section 22D does not protrude outside the edge of tabletop 10. Furthermore, when fixture 100 is moved, article placement section 22D does not come into contact with obstacles present around fixture 100, ensuring safety when moving fixture 100. Furthermore, because base plate 22 has a shape that follows the shape of tabletop 10, the area of ​​article placement section 22D on base plate 22 can be expanded as much as possible.

[0135] Because article placement section 22D has two first article placement sections 22E and two second article placement sections 22S, first article placement section 22E and second article placement section 22S can be formed in different locations on base plate 22. Furthermore, because first width W1 is different from second width W2, the sizes of first article placement section 22E and second article placement section 22S can be changed. Therefore, articles of various shapes can be placed on article placement section 22D, which has first article placement section 22E and second article placement section 22S, and the convenience of fixture 100 can be improved.

[0136] The base has walls 26X and 26Y that serve as article support surfaces, so when an item is placed on article placement section 22D, the item comes into contact with walls 26X and 26Y, maintaining the article's position. This prevents the item from tipping over on article placement section 22D. In particular, even if an office worker moves fixture 100 with an item, luggage, or the like placed on article placement section 22D, walls 26X and 26Y can prevent the item from tipping over.

[0137] Article placement section 22D is covered with second cover member 28, which is made of felt fabric. Therefore, when an article is placed on article placement section 22D, second cover member 28 is positioned between article placement section 22D and the article. This prevents the article from being damaged by friction generated between article placement section 22D and the article.

[0138] The two first article placement sections 22E are symmetrical with respect to the imaginary line LY. The two second article placement sections 22S are symmetrical with respect to the imaginary line LX. Therefore, it is possible to provide fixture 100 with excellent design.

[0139] <Modification> In the modifications described below, the same members as those shown in FIGS. 1 to 4 are denoted by the same reference numerals, and their description will be omitted or simplified.

[0140] <Variation 1> In the above-described embodiment, a structure has been described in which the power supply terminal unit 30 is disposed inside the top panel connection unit 23 that constitutes part of the support column 21. The power supply terminal unit 30 may be disposed on the lower surface 12 of the top panel 10. The connection structure connecting the lower surface 12 and the power supply terminal unit 30 is not particularly limited. The lower surface 12 and the power supply terminal unit 30 may be fixed using a known fixing member such as a screw, or the lower surface 12 and the power supply terminal unit 30 may be fixed by adhesive.

[0141] A wire holding portion for holding the wire 50 may be provided on the lower surface 12. The wire holding portion is, for example, a hook. With this configuration, the wire 50 connected to the power supply terminal portion 30 can be held by the wire holding portion.

[0142] The underside 12 is a portion that is difficult for an office worker to see, and therefore the power terminal portion 30 arranged on the underside 12 is not visually noticeable. This makes it possible to provide fixture 100 with excellent design.

[0143] <Variation 2> FIG. 5A is a side view showing fixture 101 according to Modification 2. FIG. In the fixture 101, the height of the battery storage section 25A in the Z direction is greater than the height of the fixture 100 shown in Fig. 1. In other words, in the X direction, the opening area of ​​the battery storage section 25A of the fixture 101 is greater than the opening area of ​​the battery storage section 25A of the fixture 100. In the fixture 101, a beam member 29 is provided between the first extension portion 24A and the second extension portion 24B. The beam member 29 extends in the Y direction and connects the end of the first extension portion 24A to the second extension portion 24B.

[0144] According to the fixture 101, the same effect as that of the fixture 100 described above can be obtained. Furthermore, according to fixture 101, the opening area of ​​battery storage section 25A is increased, thereby reducing the area of ​​support 21 as viewed in the X direction. Therefore, fixture 101 has a stylish shape, which can improve the design of fixture 101. Since beam member 29 is provided between the end of first extension section 24A and second extension section 24B, fixture 101 can be made to have excellent strength.

[0145] In addition, in the fixture 101, the worker can easily grasp the beam member 29. Therefore, the worker can push or pull the tabletop 10 horizontally while holding the beam member 29 with his or her fingers. In other words, the fixture 100 can be easily moved using the beam member 29.

[0146] <Variation 3> FIG. 5B is a side view showing fixture 102 according to Modification 3. FIG. The height of the fixture 102 in the Z direction, i.e., the height from the floor surface FL to the upper surface 11 of the top board 10, is lower than that of the fixture 100. The height of the fixture 102 is, for example, 600 mm. Furthermore, the width of the battery storage section 25A in the Y direction of the fixture 102 is greater than the width of the fixture 100 shown in FIG.

[0147] According to the fixture 102, the same effect as that of the fixture 100 described above can be obtained. Furthermore, according to fixture 102, the width of battery accommodating section 25A is increased, so that battery B is less likely to come into contact with first extending section 24A or second extending section 24B when attaching or detaching battery B to or from battery accommodating section 25A. Therefore, the worker can easily attach or detach battery B.

[0148] <Variation 4> FIG. 5C is a schematic cross-sectional view showing fixture 103 according to Modification 4. As shown in FIG. 5C shows the structure of the support columns 21 as seen in the −Z direction and through the tabletop 10. In FIG. 5C, the outer shape of the tabletop 10 is indicated by dotted lines.

[0149] In the fixture 103, the support 21 has a third extension portion 24C. The third extension portion 24C is connected to an end of the first extension portion 24A in the +X direction and an end of the second extension portion 24B in the +X direction. The third extension portion 24C extends from the plate connection portion 26 toward the top board connection portion 23 so as to be inclined with respect to the Z direction. In other words, the support 21 has a substantially U-shape when viewed in the Z direction.

[0150] In fixture 103, third extension 24C hides battery storage section 25A in the +X direction. In other words, third extension 24 covers battery storage section 25A so that battery B is not exposed in the +X direction. An office worker who is next to fixture 103 or far away from fixture 103 in the +X direction can see support column 21 having third extension 24C.

[0151] According to the fixture 103, the same effect as that of the fixture 100 described above can be obtained. Furthermore, according to fixture 103, third extension portion 24C covers battery housing portion 25A, so that the design of fixture 103 can be improved. In this modified example, a structure has been described in which the third extension portion 24C is provided in a portion of the support 21 located in the +X direction, but the third extension portion 24C may also be provided in a portion of the support 21 located in the -X direction.

[0152] <Variation 5> FIG. 5D is a schematic cross-sectional view showing fixture 104 according to Modification 5. 5D shows the structure of the support columns 21 as seen in the −Z direction and through the tabletop 10. In FIG. 5D, the outer shape of the tabletop 10 is indicated by dotted lines. In the fifth modification, the same members as those shown in FIG. 5C are denoted by the same reference numerals, and the description thereof will be omitted or simplified.

[0153] Like the above-described fixture 103, fixture 104 has a third extending portion 24C that connects the end of first extending portion 24A in the +X direction and the end of second extending portion 24B in the +X direction. Furthermore, fixture 104 has a hinge 24D connected to the end of first extending portion 24A in the -X direction, and a door 24E connected to hinge 24D.

[0154] Door 24E is rotatable around hinge 24D. An engaging portion that engages with the end of second extending portion 24B in the -X direction is provided at tip 24F of door 24E. That is, door 24E can perform an opening and closing operation to open and close battery housing portion 25A.

[0155] When door 24E is closed, door 24E hides battery storage section 25A in the -X direction. In other words, door 24E covers battery storage section 25A so that battery B is not exposed in the -X direction. In this case, an office worker who is located next to fixture 104 or far from fixture 104 in the -X direction can see door 24E.

[0156] When door 24E is open, battery B is exposed in the −X direction. In this case, an office worker standing next to fixture 104 in the −X direction can visually observe battery B and can install or remove battery B.

[0157] According to the fixture 104, the same effects as those of the fixtures 100 and 103 described above can be obtained. Furthermore, with fixture 104, the interior of battery storage section 25A can be hidden by closing door 24E. This improves the design of fixture 104 as seen by an office worker who is adjacent to fixture 104 or far away from fixture 104 in the -X direction. Also, by opening door 24E, battery B can be attached or detached.

[0158] In this modification, the hinge 24D and the door 24E are provided on the portion of the support 21 located in the -X direction, but the hinge 24D and the door 24E may be provided on the portion of the support 21 located in the +X direction.

[0159] <Variation 6> FIG. 5E is a schematic cross-sectional view showing fixture 105 according to Modification 6. As shown in FIG. 5E shows the structure of the support columns 21 as seen in the −Z direction and through the tabletop 10. In FIG. 5E, the outer shape of the tabletop 10 is indicated by dotted lines. In the sixth modification, the same members as those shown in FIGS. 5C and 5D are denoted by the same reference numerals, and their description will be omitted or simplified.

[0160] The fixture 105 differs from the fixture 104 in the shape of the tabletop 10 and the number of batteries B. In this modification, the tabletop 10 has a circular plate shape when viewed in the Z direction. One battery B is located in the center of the circular plate. The structures of the third extension 24C, hinge 24D, and door 24E are the same as those of the fixtures 103 and 104.

[0161] According to the fixture 105, the same effects as those of the fixtures 100, 103, and 104 described above can be obtained. Furthermore, according to the fixture 105, the shape of the top panel 10 is a disk, and the number of batteries B is one, so the thickness of the support pole 21 can be reduced. Therefore, the fixture 105 has a stylish shape, and the design of the fixture 105 can be improved.

[0162] <Variation 7> FIG. 5F is a schematic cross-sectional view showing fixture 106 according to Modification 7. 5F shows the structure of the support columns 21 as seen in the −Z direction and seen through the tabletop 10. In FIG. 5F, the outer shape of the tabletop 10 is shown by dotted lines. In the seventh modification, the support pillar 21 does not have the second extension portion 24B, but has the first extension portion 24A. In other words, the fixture 106 has a cantilever structure.

[0163] An office worker who is next to or far from the fixture 106 in the +Y direction, the -X direction, and the +X direction can visually check the battery storage unit 25A arranged on the fixture 106 and can confirm whether or not a battery B is stored in the battery storage unit 25A. The office worker can reach out their fingers to the battery storage unit 25A and remove the battery B stored in the battery storage unit 25A from the battery storage unit 25A or store the battery B in the battery storage unit 25A. This makes it even easier to install and remove the battery B. In addition, the battery B can be hidden when viewed in the -Y direction, improving the design.

[0164] 5C to 5E, the support pillar 21 has a substantially U-shape when viewed in the Z direction, but the support pillar 21 may have a substantially C-shape. Specifically, the combined shape of the first extension portion 24A, the second extension portion 24B, and the third extension portion 24C may have a substantially C-shape when viewed in the Z direction. In addition, in a structure including the door 24E, the shape formed by combining the first extension portion 24A, the second extension portion 24B, the third extension portion 24C, and the door 24E may have a substantially O-shape when viewed in the Z direction.
