Description

[Technical Field]

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

[0002] In conference rooms and work spaces in offices, public facilities, schools, residences, etc., furniture with a top that provides a work surface for workers to work on is used. Electronic devices are generally used in office work. Power supply to electronic devices is important for working with electronic devices, and office furniture that can supply power to electronic devices is required. Such furniture utilizes power supplied from power outlets installed on the walls or floors that form the work space, for example.

[0003] In recent years, office furniture (movable tables) that supply power to electronic devices from pre-charged batteries have become known (see, for example, Patent Document 1). In this furniture, the battery storage compartment is fixed to the side of the table body by mounting brackets located in two positions, one above the other. Furniture with this configuration not only makes it possible to supply power to electronic devices from the battery, but also makes it possible to freely change the location of the furniture, since there is no need to connect wiring to the furniture. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 3839906 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the fixture described in Patent Document 1 has a structure in which the storage section is fixed to the side of the table body, and therefore when the battery is stored in the storage section, the weight of the battery makes it difficult to stabilize the position of the fixture's center of gravity.

[0006] The present invention has been made in consideration of the above problems, and aims to provide a display unit with a top that can supply power from a battery to electronic devices and stabilize the position of the center of gravity. [Means for solving the problem]

[0007] A furniture unit with a top plate according to one aspect of the present invention includes a top plate having an upper surface that is a work surface and a lower surface located opposite the upper surface, a base that supports the lower surface of the top plate and has a battery storage section that can store a battery, a power terminal section that is located on the base or the top plate, wiring that electrically connects the power terminal section and the battery, and casters that support the base and can run on a floor surface. The battery storage section is located inside the base.

[0008] According to the fixture with a top plate according to the above aspect, the battery storage unit capable of storing the battery is located inside the base, which minimizes the space required for installing the battery in the fixture with a top plate. Furthermore, since the battery storage unit is located inside the base, the center of gravity of the fixture with a top plate can be more stable than in a structure in which the battery storage unit that stores the battery is located outside the base.

[0009] 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 tabletop-equipped furniture are misaligned, making the tabletop-equipped furniture unstable and difficult to move smoothly.

[0010] In contrast, with a structure of a tabletop-equipped fixture in which the battery storage unit is located inside the base, when the battery is stored in the battery storage unit, the center of gravity of the battery and the center of gravity of the tabletop-equipped fixture are less likely to shift from each other. This makes it possible to stabilize the center of gravity of the tabletop-equipped fixture. Therefore, when moving the tabletop-equipped fixture, the tabletop-equipped fixture is less likely to tip over, and can be moved smoothly.

[0011] Furthermore, the tabletop-equipped furniture according to the above-mentioned aspect includes a power terminal unit located on the base or tabletop, wiring that electrically connects the power terminal unit to the battery storage unit, and casters that support the base and can move along the floor. This eliminates the need to connect the tabletop-equipped furniture to outlets installed on the walls or floor that form the office space. Furthermore, tabletop-equipped furniture equipped with casters can be moved.

[0012] This allows users of the tabletop-equipped fixture to move it to any position they like and use it. Because there are no restrictions on where the tabletop-equipped fixture can be used in the office space, the convenience of the tabletop-equipped fixture can be increased.

[0013] In one aspect of the present invention, when viewed from the top of the fixture, the position of the center of gravity of the top, the position of the center of gravity of the base, and the position of the center of gravity of the battery may coincide.

[0014] According to the above-described aspect of the tabletop-equipped fixture, the center of gravity of the tabletop, the center of gravity of the base, and the center of gravity of the battery are all aligned, so when a battery is stored in the battery compartment, the center of gravity of the tabletop-equipped fixture will not shift due to the weight of the battery. This allows the tabletop-equipped fixture to have a stable center of gravity. Therefore, when the tabletop-equipped fixture is moved, it is less likely to tip over, allowing for smooth movement.

[0015] In one aspect of the present invention, the wiring may be arranged inside the base. According to the fixture with a tabletop according to the above-mentioned embodiment, the wiring is not exposed to the outside of the base. In other words, the wiring can be hidden by the base. Therefore, it is possible to prevent the design from being impaired by the wiring being exposed to the outside of the base, and in other words, it is possible to provide a fixture with a tabletop that has excellent design.

[0016] In one aspect of the present invention, the power supply terminal portion may be located on the base, and the upper surface of the top plate may be a single plane. According to the above-described embodiment of the tabletop-equipped fixture, the power terminal is not located on the tabletop, making it less visually noticeable. Therefore, it is possible to provide a tabletop-equipped fixture with excellent design. Since the top surface of the tabletop is a single plane without any recesses or protrusions, such as wiring outlets where power strips for supplying power to electronic devices can be placed, a large work surface can be secured, improving the convenience of the tabletop-equipped fixture.

[0017] The fixture with a top plate according to one aspect of the present invention may further include an article tray positioned below the lower surface of the top plate. The article tray may be supported by the base. According to the above-described aspect of the display unit with a tabletop, a user can place items on the tray. Furthermore, the display unit with a tabletop can be moved while the items are placed on the tray. This improves the ease of use of the display unit with a tabletop.

[0018] In a fixture with a top plate according to one aspect of the present invention, the power terminal portion may be disposed between the underside of the top plate and the item tray. According to the above-described aspect of the display unit with a top, when a user uses an electronic device, the electronic device can be electrically connected to the power terminal via a power cable. Furthermore, the excess portion of the power cable can be placed on the item tray. This improves the ease of use of the display unit with a top. [Effects of the Invention]

[0019] According to the fixture with a top plate according to this aspect of the present invention, it is possible to supply power from a battery to electronic devices, and the position of the center of gravity of the fixture with a top plate can be stabilized. [Brief explanation of the drawings]

[0021] A fixture according to one 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).

[0024] Of the two directions perpendicular to the up-down direction, the shorter side of the tabletop is called the depth direction (X direction). One of the depth directions is called the forward direction (+X direction), and the opposite direction is called the rearward direction (-X 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 term "user" used in this embodiment does not mean a person who uses an electronic device placed on the top plate of a fixture. A person who places an item or luggage on the top plate, 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 a user. Note that since a user is in an office space, the user may also be referred to as an office worker.

[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] 1 and 2, the furniture 100 according to this embodiment includes a top panel 10, a base 20, a power terminal 30, a discharger 40, wiring 50, casters 60, and an article tray 70. A battery B, which will be described later, is detachable from the discharger 40.

[0030] <Tabletop> The top panel 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 a wiring outlet where a power strip for supplying power to an electronic device can be placed. In other words, the upper surface 11 does not have any uneven parts that would interfere with the user's work. The upper surface 11 is a work surface on which the user performs work. In other words, the user can operate the electronic device while placing it 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. Because the edge 10E protrudes in the X and Y directions further than the base 20, a user can easily grip the tabletop 10. Therefore, when moving the fixture 100, the user can grip 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] <Base> The base 20 is a member that supports the top panel 10. The base 20 has a support 21, a base plate 22, a top panel connection portion 23, a first extension portion 24A, a second extension portion 24B, a battery accommodating portion 25A, a unit accommodating portion 25B, a plate connection portion 26, a first cover member 27, and a second cover member 28.

[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] <Strut> The support pillar 21 is composed of a top panel 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. The support pillar 21 is an example of an upper member that constitutes the base portion 20.

[0039] 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.

[0040] 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.

[0041] <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. That is, the base 20 supports 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.

[0042] A power supply terminal section 30 is provided inside the top panel connection section 23. The top plate connection portion 23 has a support pillar opening 23B formed on the surface of the support pillar 21. The support pillar opening 23B is formed on a surface of the support pillar 21 facing the +X direction and a surface facing the -X direction. The support pillar opening 23B exposes a plug insertion port 31 of a power terminal portion 30 (described later) to the outside of the support pillar 21. In other words, the top plate connection portion 23 exposes two power terminal portions 30 to the outside of the support pillar 21.

[0043] 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.

[0044] <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.

[0045] <Battery compartment> Battery storage section 25A is provided inside base 20. The phrase "inside base 20" means "inside support 21." In other words, the phrase "inside base 20" means that battery storage section 25A is formed at a position inside contour 21E that forms the outer shape of support 21 of base 20 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.

[0046] <Unit storage area> The unit accommodating portion 25B is provided inside the base portion 20. 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.

[0047] 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.

[0048] The user can visually check battery storage section 25A and can confirm whether battery B is stored in battery storage section 25A. The user can reach out with his or her fingers to battery storage section 25A to remove battery B stored in battery storage section 25A from battery storage section 25A or store battery B in battery storage section 25A.

[0049] 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.

[0050] <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.

[0051] <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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] <Base plate> The base plate 22 is located on the opposite side of the top plate connection portion 23 in the Z direction. The base plate 22 is an example of a lower member that constitutes the base portion 20. The base plate 22 has the function of supporting the base portion 20, and is therefore an example of a support member. The base plate 22 is a plate-like member that is connected to the plate connection portion 26.

[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.

[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 the 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 the surface to which the casters 60 are connected. 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] 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. 1 and 2, the planar shape of the base plate 22 is substantially rectangular. As long as the position of the fixture 100 can be stabilized, the shape of the base plate 22 is not limited.

[0060] <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 base 20. 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 known caster part that is commercially available.

[0061] 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.

[0062] In this embodiment, the base plate 22, which is a plate-like member, is used as an example of the lower member constituting the base 20, but a member other than a plate-like member may be used as the lower member. For example, the lower member may be a leg member equipped with a rod having a tip end to which the caster 60 is fixed. For example, the leg member may be a leg that is used for a known chair or the like.

[0063] <Item tray> The article tray 70 is fixed to the top panel connection portion 23. The article tray 70 is supported by the base portion 20 so as to surround the periphery of the base portion 20. 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.

[0064] The article tray 70 can accommodate the user'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 user's luggage and small items that can be placed on the article tray 70 include smartphones, handbags, handkerchiefs, cosmetics, newspapers, books, etc. The types of luggage and small items are not limited as long as they are items that the user carries.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] Plate member 71 of article tray 70 has tray upper surface 71A and tray flange 70F. Tray upper surface 71A can accommodate not only a user's articles but also the excess portion of a power cable connected to an electronic device.

[0070] 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.

[0071] In the X and Y directions, tray flange 70F does not protrude outside edge 10E of top plate 10. In other words, when viewed in the -Z direction, tray flange 70F is located inside the area surrounded by edge 10E of top plate 10.

[0072] 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.

[0073] <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.

[0074] 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.

[0075] 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.

[0076] <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.

[0077] <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.

[0078] 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.

[0079] 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.

[0080] The inverter 44c is a converter that converts DC power output from the battery B into AC power. As shown in FIG.

[0081] 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.

[0082] In this configuration, the user can visually determine whether or not the battery B is attached to the attachment recess 44b1. The user can install the battery B in the attachment recess 44b1 and remove the battery B from the attachment recess 44b1. In other words, the user can easily replace the battery B.

[0083] 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.

[0084] 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.

[0085] <Wiring> The wiring 50 is a member that electrically connects the power supply terminal unit 30 and the battery B (discharge unit 40). Specifically, when the battery B is accommodated in the battery accommodation unit 25A and the battery B is placed on the discharge unit 40, the inverter 44c of the discharge unit 40 and the battery B are electrically connected. In this state, the wiring 50 electrically connects the power supply terminal unit 30 and the battery B, and supplies the power of the battery B to the power supply terminal unit 30.

[0086] The wiring 50 is arranged inside the base 20. In other words, the wiring 50 is arranged inside the plate connecting portion 26, the second extending portion 24B, and the top plate connecting portion 23 that constitute the support 21. The wiring 50 extends approximately in the Z direction inside the support 21. A guide portion that regulates the extension direction of the wiring 50 may be arranged inside the support 21.

[0087] The wiring 50 is connected to the power supply terminal portion 30 arranged on the top panel connection portion 23. The wiring 50 may pass through the first extension portion 24A without passing through the second extension portion 24B, or may pass through both the first extension portion 24A and the second extension portion 24B. The wiring 50 may also be referred to as internal wiring.

[0088] <Power terminal section> The power terminal unit 30 is a component to which a power cable connected to a user's electronic device is connected. As shown in Figures 1 and 2, the power terminal unit 30 is disposed between the underside 12 of the top panel 10 and the article tray 70 in the Z direction. The power terminal unit 30 is disposed inside the top panel connection unit 23 that constitutes part of the base 20.

[0089] 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 unit, or a socket. The power terminal unit 30 is disposed on the top panel connection unit 23, which is part of the base unit 20.

[0090] 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.

[0091] 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.

[0092] The power supply terminal unit 30 may include, for example, a USB (Universal Serial Bus) outlet tap. The USB outlet tap converts AC power to 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 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.

[0093] <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.

[0094] 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.

[0095] 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 to 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.

[0096] <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.

[0097] The handle B2 extends in the +Z direction and has a curved shape. A user 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.

[0098] 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.

[0099] Display unit B3 displays the remaining charge of battery B. The user 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.

[0100] 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.

[0101] <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.

[0102] 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.

[0103] 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.

[0104] 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. Each of the wires 50 conducts AC power output from the inverter 44c to the plug insertion port 31.

[0105] 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.

[0106] Furthermore, when replacing the battery B, the user removes the battery B, which was previously attached to the discharger 40, from the discharger 40 by lifting it up from the attachment recess 44b1. Thereafter, the user attaches a new battery B to the attachment recess 44b1 from above.

[0107] <Center of gravity of fixtures> The symbol GP shown 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 fixture 100 has a shape that is line-symmetric with respect to the imaginary line LY and also has a shape that is line-symmetric with respect to the imaginary line LX. When viewed in the Z direction, the position of the center of gravity of the top board 10, the position of the center of gravity of the base 20, 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.

[0108] <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 base 20, 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 base 20, 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 base 20.

[0109] 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.

[0110] In contrast, with the structure of fixture 100 in which battery storage section 25A is disposed inside base 20, 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.

[0111] Furthermore, the fixture 100 according to this embodiment includes a power terminal unit 30 disposed on the base 20, wiring 50 electrically connecting the power terminal unit 30 and the battery storage unit 25A, and casters 60 connected to the base 20. This eliminates the need to connect the fixture 100 to outlets provided on the walls and floors that form the office space.

[0112] Therefore, a user of the fixture 100 can freely move the fixture 100 to a position where they like and use the fixture 100. Since there are no restrictions on the position where the fixture 100 can be used in the office space, the convenience of the fixture 100 can be improved.

[0113] In the Z direction, the position of the center of gravity of the tabletop 10, the position of the center of gravity of the base 20, 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.

[0114] The wiring 50 is arranged inside the base 20. Therefore, the wiring 50 is not exposed to the outside of the base 20. In other words, the wiring 50 can be hidden by the base 20. Therefore, it is possible to prevent a decrease in design due to the wiring 50 being exposed to the outside of the base 20, and in other words, it is possible to provide fixture 100 with excellent design.

[0115] The power terminal unit 30 is disposed on the base 20. In other words, the power terminal unit 30 is not disposed on the top plate 10. This makes the power terminal unit 30 less visually noticeable. This makes it possible to provide a fixture 100 with excellent design. 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.

[0116] The single plane of top surface 11 does not have any recesses or protrusions, such as a wiring outlet where a power strip for supplying power to an electronic device would be placed. 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 a case, the liquid will not come into contact with the electronic device placed on top surface 11, preventing the electronic device from breaking down.

[0117] The item tray 70 is located below the underside 12 of the tabletop 10 and is supported by the base 20. This allows a user to place items on the item tray 70. Furthermore, the fixture 100 can be moved with items placed on the item tray 70. This improves the ease of use of the fixture 100.

[0118] When viewed in the -Z direction, the tray flange 70F of the item tray 70 does not protrude outside the edge 10E of the top plate 10. Therefore, for example, when a container containing a liquid such as a beverage is placed on the top plate 10, even if a user'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.

[0119] The power terminal section 30 is disposed between the underside 12 of the tabletop 10 and the item tray 70. Therefore, when a user 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.

[0120] 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. Furthermore, the user can insert his or her fingers into the battery accommodating section 25A from both the +X direction and the −X direction. This allows the user to grasp the battery B from both the +X direction and the −X direction and remove the battery B from the discharge section 40. Furthermore, the user can install the battery B in the discharge section 40 from both the +X direction and the −X direction.

[0121] Casters 60 are arranged on the underside 22B of the base plate 22, so the user can move the fixture 100 by holding the tabletop 10 with their fingers and pushing or pulling it horizontally. The user 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 base 20, 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.

[0122] <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.

[0123] <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 plate connection unit 23 that constitutes part of the base unit 20. The power supply terminal unit 30 may be disposed on the underside 12 of the top plate 10. The connection structure connecting the underside 12 and the power supply terminal unit 30 is not particularly limited. The underside 12 and the power supply terminal unit 30 may be fixed using a known fixing member such as a screw, or the underside 12 and the power supply terminal unit 30 may be fixed by adhesive.

[0124] 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.

[0125] The underside 12 is a portion that is difficult for the user 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.

[0126] <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.

[0127] 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.

[0128] In addition, in the fixture 101, a user can easily grasp the beam member 29. Therefore, the user can push or pull the tabletop 10 horizontally while holding the beam member 29 with their fingers. In other words, the fixture 100 can be easily moved using the beam member 29.

[0129] <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.

[0130] 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 user can easily attach or detach battery B.

[0131] <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.

[0132] 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.

[0133] 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. A user who is located next to fixture 103 or far away from fixture 103 in the +X direction can see support pole 21 having third extension 24C.

[0134] 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.

[0135] <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.

[0136] 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.

[0137] 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.

[0138] When door 24E is closed, door 24E hides battery housing section 25A in the -X direction. In other words, door 24E covers battery housing section 25A so that battery B is not exposed in the -X direction. In this case, a user who is located next to fixture 104 or far from fixture 104 in the -X direction can see door 24E.

[0139] When door 24E is open, battery B is exposed in the -X direction. In this case, a user standing next to fixture 104 in the -X direction can visually check battery B and can install or remove battery B.

[0140] 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 a user 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.

[0141] 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.

[0142] <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.

[0143] 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.

[0144] 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.

[0145] <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.

[0146] A user who is next to or far away from fixture 106 in the +Y direction, the -X direction, and the +X direction can visually check battery storage section 25A arranged on fixture 106 and can confirm whether battery B is stored in battery storage section 25A. The user can reach out their fingers to battery storage section 25A to remove battery B stored in battery storage section 25A from battery storage section 25A or store battery B in battery storage section 25A. This makes it even easier to install and remove battery B. In addition, battery B can be hidden when viewed in the -Y direction, improving the design.

[0147] 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.

[0150] The electronic devices D1 and D2 are connected to the power terminal unit 30 of the fixture 102 via a power cable (not shown). That is, the electronic devices D1 and D2 are driven by power supplied from the battery B of the fixture 102. Similarly, the electronic device D3 is connected to the power terminal unit 30 of the fixture 100 via a power cable (not shown). That is, the electronic device D3 is driven by power supplied from the battery of the fixture 100. The electronic device D4 is charged with power supplied from the battery B of the fixture 100. Therefore, the electronic device D4 is operated without using a power cable.
