This makes it possible to connect the positive and negative terminals to the terminals of the connection destination (in this embodiment, the mounting part 11c described later) regardless of the rotation position of the mobile battery B around the axis.

[0040] The wagon 1 includes a wagon body 11, casters 12 (rolling parts), a power supply part 13, and a charging part 14. As shown in Fig. 1 and Fig. 2, the wagon body 11 has a shape in which a plurality of shelf parts 11a (storage parts) and a vertical plate part 11b that connects the plurality of shelf parts 11a to each other in the vertical direction are integrated.

[0041] The shelf section 11a is a plate-shaped portion on which a plurality of mobile batteries B can be placed and stored. In this embodiment, three shelf sections 11a are provided, arranged in the vertical direction. Each shelf section 11a is provided with an attachment section 11c (installation section) on which the mobile battery B can be installed. In this embodiment, each shelf section 11a is provided with a plurality of attachment sections 11c (four in this embodiment). These four attachment sections 11c are arranged along the longitudinal direction of the shelf section 11a, which has a rectangular shape in a plan view.

[0042] As shown in FIG. 1, each mounting portion 11c is provided with a recess 11d in which the mobile battery B can be attached. The diameter of the recess 11d is larger than the diameter of the lower part of the mobile battery B, and the lower part of the mobile battery B can be accommodated therein. The shape of the recess 11d is not particularly limited, and may be, for example, a crater-like shape curved toward the bottom at the center in a plan view. Each recess 11d is provided with a terminal portion connected to each of the negative terminal and the positive terminal of the bottom of the mobile battery B attached to the mounting portion 11c.

[0043] 3, these mounting parts 11c are electrically connected to the power supply unit 13 and the charging unit 14. That is, the power supply unit 13 and the charging unit 14 are electrically connected to the mobile battery B attached to the mounting parts 11c.

[0044] The vertical plate portion 11b connects the ends of the three shelf plate portions 11a that are arranged so as to overlap when viewed from the top-bottom direction. In this embodiment, two vertical plate portions 11b are provided. One vertical plate portion 11b connects one end of the three vertical plate portions 11b in the longitudinal direction. The other vertical plate portion 11b connects the other end of the three vertical plate portions 11b in the longitudinal direction.

[0045] Each of the vertical plate portions 11b has an outer surface provided with a handle portion 11e that is held by a user when moving the wagon 1. The outer surface of one of the vertical plate portions 11b has two outlets 13b (plug-in portions) (described later) provided in the power supply unit 13. As shown in FIG. 1, these outlets 13b are disposed below the handle portion 11e.

[0046] In such a wagon body 11, the mobile battery B can be attached and detached to the mounting portion 11c provided on the shelf portion 11a, and the mobile battery B attached to the mounting portion 11c is stored on the shelf portion 11a. The mobile battery B attached to the mounting portion 11c is simply placed on the bottom of the recess 11d, and can be removed from the mounting portion 11c without resistance by the user lifting it up. Note that the mobile battery B placed on the bottom of the recess 11d has a positive terminal and a negative terminal (not shown) provided on the bottom surface in contact with the terminal portion provided on the mounting portion 11c.

[0047] The casters 12 are connected to the underside of the wagon body 11 and support the wagon body 11 from below. The casters 12 are capable of rolling on the floor, allowing the wagon body 11 to move smoothly along the floor surface. Such casters 12 are arranged at the four corners of the wagon body 11 in a plan view. The number and arrangement of the casters 12 can be changed as desired within a range in which the wagon body 11 can be stably supported.

[0048] The power supply unit 13 supplies the power stored in the mobile battery B to an external electrical device. The power supply unit 13 includes, for example, an inverter 13a and an outlet 13b. The inverter 13a is disposed at a midpoint of the connection wiring 13c that connects the mounting unit 11c and the outlet 13b, and converts the DC power output from the mobile battery B into AC power. By converting the DC power into AC power in this way, the inverter 13a makes it possible to extract AC power similar to that of a general commercial power source from the outlet 13b. The inverter 13a is fixed to, for example, the underside of the wagon body 11.

[0049] The outlet 13b is designed to accept an attachment plug of an external electrical device, and is shaped according to a general standard. As shown in FIG. 1, in this embodiment, two outlets are provided on the outer surface of the vertical plate portion 11b of the wagon body 11. Note that in FIG. 3, one outlet 13b is omitted. The location of the outlet 13b is not limited to the outer surface of the vertical plate portion 11b, and it is also possible to arrange it in other positions, such as the upper surface of the shelf portion 11a. Furthermore, the number of outlets 13b is not limited to two, and may be one or three or more.

[0050] The charging unit 14 is detachable from an external power source (e.g., a commercial power source) and supplies power from the external power source to the mobile battery B via the attachment unit 11c. As shown in FIG. 3, the charging unit 14 includes, for example, a converter 14a and an attachment plug 14b. The converter 14a is provided at a midpoint of the connection wiring 14c that connects the attachment unit 11c and the attachment plug 14b, and converts AC power supplied from the external power source into DC power. By converting AC power into DC power in this way, the converter 14a supplies DC power to the mobile battery B, enabling the mobile battery B to be charged. Such a converter 14a is fixed, for example, to the underside of the wagon body 11.

[0051] The attachment plug 14b is designed to be pluggable into a socket provided on an external power source, and its shape is set in accordance with a general standard. A part of the connection wiring 14c on the attachment plug 14b side is pulled out from the wagon body 11 as a power cable 14d, as shown in Figures 1 and 2.

[0052] In the fixture system S1 of this embodiment, when power is supplied from the outlet 13b to an external electrical device, a charged mobile battery B is attached to the attachment section 11c. This causes the power supply section 13 to supply power from the mobile battery B to the electrical device.

[0053] In addition, in the fixture system S1 of this embodiment, when charging the mobile battery B, the plug 14b of the charging unit 14 is inserted into an outlet of an external power source, and the mobile battery B is attached to the attachment unit 11c. This supplies DC power to the mobile battery B, and the mobile battery B is charged.

[0054] In addition, when the attachment plug 14b is inserted into the outlet of the external power source and an electrical device is connected to the outlet 13b of the power supply unit 13, both charging of the mobile battery B and supply of power to the electrical device are performed.

[0055] The wagon 1 provided in the fixture system S1 of this embodiment as described above has an attachment section 11c on which a mobile battery B can be installed, and a power supply section 13 that supplies power from the mobile battery B attached to the attachment section 11c to electrical equipment.

[0056] According to the wagon 1 of this embodiment, the mobile battery B can be installed, and the power of the installed mobile battery B can be supplied to an external electrical device. Therefore, it is possible to supply power to an electrical device without connecting the wagon 1 to an external power source. Therefore, according to the wagon 1 of this embodiment, it is not necessary to connect to an external power source with the power cable 14d in order to supply power to an external electrical device. Therefore, it is not necessary to connect the power cable 14d of the wagon 1 to a commercial power source at all times. Therefore, according to the wagon 1 of this embodiment, it is possible to improve the freedom of arrangement and design, and further improve the freedom of work using electrical devices.

[0057] In addition, in the wagon 1 of this embodiment, the power supply unit 13 includes a socket 13b to which the plug of an electrical device can be connected. This makes it possible to connect electrical devices that are used by connecting them to a socket in a general home, office, etc. Therefore, according to the wagon 1 of this embodiment, it is possible to supply power from the mobile battery B to electrical devices that are used by connecting them to a socket in a general home, office, etc. In this way, according to the wagon 1 of this embodiment, since it includes the socket 13b, the plug of any electrical device can be connected to the socket 13b, and the user can use any electrical device.

[0058] Moreover, the wagon 1 of this embodiment includes a shelf portion 11a capable of storing the mobile battery B, and a mounting portion 11c is provided on the shelf portion 11a. This makes it possible to supply power from the mobile battery B to an electrical device in the fixture in which the mobile battery B is stored. This makes it possible to supply power from the mobile battery B to the electrical device when the mobile battery B is stored.

[0059] Moreover, the wagon 1 of this embodiment is provided with casters 12 that can roll on the floor. Therefore, the casters 12 roll on the floor, allowing the wagon 1 to be moved smoothly.

[0060] The wagon 1 of this embodiment is provided with a charging unit 14 that is detachable from an external power source and supplies power from the external power source to the mobile battery B via the mounting portion 11c. Therefore, by connecting the charging unit 14 to an external power source as necessary, it is possible to charge the mobile battery B.

[0061] Moreover, in this embodiment, the furniture system S1 includes the above-mentioned wagon 1 and a mobile battery B. Such furniture system S1 includes the wagon 1 on which the mobile battery B can be installed, and the wagon 1 can supply power from the mobile battery B to electrical equipment. This eliminates the need to keep the wagon 1 connected to an external power source at all times, improving the freedom of arrangement and design of the wagon 1, and further improving the freedom of work using electrical equipment.

The shelf 91 is a furniture that supports the monitor 92, and includes a shelf portion 91a (support portion), a base portion 91b, and a power supply portion 91c, as shown in Fig. 14.

[0155] The shelf portion 91a includes a frame-shaped shelf frame 91d and a shelf board 91e supported by the shelf frame 91d. The shelf frame 91d is a frame-shaped member that supports the shelf board 91e. The shelf frame 91d is a frame-shaped member that is supported from below by the base portion 91b. The shelf board 91e is a plate-shaped member that is supported by the shelf frame 91d and has an upper surface that serves as a surface for placing items.

[0156] The base 91b supports the shelf 91a from below so that the shelf 91a can be erected. The base 91b is hollow and accommodates a converter and the like that are part of the power supply unit 91c in this embodiment. That is, in this embodiment, a part of the power supply unit 91c is accommodated in the base 91b.

[0157] Furthermore, in the fixture system S9 of this embodiment, as shown in Fig. 14, a plurality of mounting sections 91f on which the mobile battery B can be installed are provided on the base section 91b. The mounting sections 91f have a recess into which the mobile battery B can be attached. The recess has a diameter larger than the diameter of the lower part of the mobile battery B and is capable of accommodating the lower part of the mobile battery B. The recess is provided with terminal sections connected to the negative and positive terminals of the bottom part of the mobile battery B attached to the mounting sections 91f.

[0158] These attachment parts 91f are electrically connected to the power supply unit 91c. That is, the power supply unit 91c is electrically connected to the mobile battery B attached to the attachment parts 91f. The power supply unit 91c supplies the power stored in the mobile battery B to the monitor 92. This power supply unit 91c includes, for example, a converter that converts the DC power supplied from the mobile battery B into a voltage suitable for the monitor 92. The monitor 92 is an electronic device that displays information using the power supplied from the power supply unit 91c.

[0159] According to the shelf 91 of this embodiment, the mobile battery B can be installed, and the power of the installed mobile battery B can be supplied to the electrical device. Therefore, it is possible to supply power to the electrical device without connecting the shelf 91 to an external power source. Therefore, according to the shelf 91 of this embodiment, it is not necessary to connect to an external power source with a power cable in order to supply power to the electrical device. Therefore, according to the shelf 91 of this embodiment, it is possible to improve the freedom of arrangement and design, and further improve the freedom of work using the electrical device.

[0160] Moreover, the shelf 91 of this embodiment includes a base portion 91b, and the mounting portion 91f is provided on the base portion 91b. Therefore, it is possible to supply power from the mobile battery B to an electrical device with the mobile battery B placed on the base portion 91b. Also, the mobile battery B can be attached to the base portion 91b, and the mobile battery B can be stably supported by the base portion 91b.

[0161] In addition, the shelf 91 of this embodiment is provided with a plurality of attachment portions 91f. This makes it possible to attach a plurality of mobile batteries B to the shelf 91, and makes it possible to supply power to the monitor 92 for a long period of time.

[0162] In the shelf 91 of this embodiment, a part of the power supply unit 91c is accommodated inside the base portion 91b. This prevents at least a part of the power supply unit 91c from being visible from the outside, and prevents the power supply unit 91c from affecting the design of the shelf 91.

[0163] Moreover, in this embodiment, the furniture system S9 includes the above-mentioned shelf 91 and a mobile battery B. Such furniture system S9 includes the shelf 91 on which the mobile battery B can be installed, and the shelf 91 can supply power from the mobile battery B to an electrical device. This eliminates the need to connect the shelf 91 to an external power source, improving the freedom of arrangement and design of the shelf 91, and further improving the freedom of work using electrical devices.

[0164] Note that, instead of the monitor 92, other electrical devices such as a signage or a tablet can be connected to the shelf 91 of the present embodiment. Also, in addition to the monitor 92, other electrical devices can be connected.

[0165] Tenth embodiment Next, a tenth embodiment of the present invention will be described. In the description of this embodiment, the description of the same parts as those in the first embodiment will be omitted or simplified.

[0166] 15 is an exploded perspective view of the desk 6 (furniture) of this embodiment. As shown in this figure, the desk 6 of this embodiment is a furniture that provides a work surface on which a user can place electronic devices and the like, and includes a plurality of legs 6a, a top plate 6b, a battery tray 6c (tray), a wiring duct 6d (wiring housing section), and a power supply section 6e.

[0167] Each leg 6a is connected to the lower surface of the top plate 6b and supports the top plate 6b from below. The top plate 6b is a plate-like member with the front and back sides facing in the up-down direction, and in this embodiment, is rectangular in plan view with the left-right direction as the long side and the front-rear direction as the short side. The top plate 6b is supported from below by the legs 6a, which are fixed at each of the four corners in plan view with fasteners (not shown). The upper surface of such a top plate 6b forms a work surface on which electronic devices and the like are placed. In this embodiment, a central opening 6b1 in which a battery tray 6c is placed is provided in the center of the top plate 6b. In addition, four outlets 6e4 (receptacle portions) described later that are provided in the power supply unit 6e are provided on the top plate 6b.

[0168] Fig. 16 is a cross-sectional view of the top plate 6b including the battery tray 6c and the wiring duct 6d, viewed from above the top plate 6b. Fig. 17 is a cross-sectional view of the top plate 6b including the battery tray 6c and the wiring duct 6d, viewed from below the top plate 6b.

[0169] The battery tray 6c is a tray member provided with a plurality of mounting portions 6c3 to which mobile batteries are attached. As shown in Fig. 16 and Fig. 17, the battery tray 6c has an upper tray 6c1 and a lower tray 6c2.

[0170] The upper tray 6c1 is a plate-like portion slightly larger than the central opening 6b1 formed in the top plate 6b, and the edge portion is placed on the top surface of the top plate 6b from above. A plurality of attachment portions 6c3 are provided on the top surface of the upper tray 6c1. The upper tray 6c1 also has a claw portion 6c4 that is inserted into the central opening 6b1. The lower tray 6c2 is formed to have a container shape with an outer shape smaller than the central opening 6b1, and the side wall portion is engaged with the claw portion 6c4 of the upper tray 6c1. A boss portion 6c5 for screwing a screw is provided on the bottom of the lower tray 6c2. The upper tray 6c1 and the lower tray 6c2 are formed of, for example, resin. A plurality of boss portions 6c5 are provided along the longitudinal direction of the top plate 6b. The lower surface of the lower tray 6c2 is disposed to be the same or approximately the same as the lower surface of the top plate 6b in the height direction.

[0171] The mounting portion 6c3 provided on the upper surface of the upper tray 6c1 has a recess in which the mobile battery can be attached. The diameter of the recess is larger than the diameter of the lower part of the mobile battery, and the lower part of the mobile battery can be accommodated. The recess is provided with terminal portions connected to the negative and positive terminals of the bottom of the mobile battery attached to the mounting portion 6c3.

[0172] These attachment parts 6c3 are electrically connected to the power supply unit 6e. That is, the power supply unit 6e is electrically connected to the mobile battery attached to the attachment parts 6c3. The power supply unit 6e supplies the power stored in the mobile battery to an electric device (not shown) connected to the outlet 6e4.

[0173] The wiring duct 6d can accommodate wiring and is fixed to the battery tray 6c to reinforce the battery tray 6c. The wiring duct 6d includes, for example, a bottom wall portion 6d1 and a reinforcing beam 6d2, and is made of, for example, metal. Such a wiring duct 6d has a higher rigidity than the battery tray 6c.

[0174] The bottom wall portion 6d1 is disposed opposite to the lower surface of the lower tray 6c2 of the battery tray 6c, and forms a space capable of accommodating wiring between the bottom wall portion 6d1 and the lower surface of the lower tray 6c2. The edge of the bottom wall portion 6d1 protrudes upward and is fastened to the lower surface of the top plate 6b with screws (not shown). The bottom wall portion 6d1 is provided with an opening for each boss portion 6c5 that exposes the boss portion 6c5 provided on the lower tray 6c2.

[0175] The reinforcing beam 6d2 extends along the longitudinal direction of the top plate 6b and protrudes upward from the upper surface of the bottom wall 6d1. As shown in Figures 16 and 17, the reinforcing beam 6d2 is formed by bending a plate material so that the center protrudes upward beyond the edge, and is formed into a so-called hat shape. The edge of such a reinforcing beam 6d2 is welded to, for example, the bottom wall 6d1, and the center is abutted against the lower surface of the lower tray 6c2.

[0176] The battery tray 6c is reinforced by the wiring duct 6d by abutting the reinforcing beam 6d2 against the lower surface of the lower tray 6c2. The reinforcing beam 6d2 has screw insertion holes provided for each boss portion 6c5 in accordance with the boss portion 6c5. As shown in Figures 16 and 17, the wiring duct 6d is fixed to the battery tray 6c by screwing a screw 6f inserted into the screw insertion hole from below into the boss portion 6c5.

[0177] The power supply unit 6e includes a connection wiring 6e1 connected to the mounting portion 6c3, a control unit 6e2 that houses an inverter and a control unit, a connection wiring 6e3 that connects the control unit 6e2 to an outlet 6e4, and the outlet 6e4 to which an electrical device is connected.

[0178] The connection wiring 6e1 is connected to the mounting portion 6c3 via a conductive path (not shown) provided in the battery tray 6c. The connection wiring 6e1 is also drawn out from the battery tray 6c, supported by a wiring duct 6d, and connected to the control unit 6e2.

[0179] The control unit 6e2 is housed in, for example, the wiring housing space of the wiring duct 6d. As described above, the control unit 6e2 includes an inverter. The inverter converts the DC power output from the mobile battery into AC power. This allows AC power similar to that of a general commercial power source to be extracted from the outlet 6e4.

[0180] In addition, the control unit 6e2 includes a control unit as described above. When multiple mobile batteries are attached to the attachment parts 6c3, the control unit 6e2 controls which mobile battery supplies power to the outlet 6e4 (i.e., the electrical device). For example, when multiple mobile batteries are attached, the control unit 6e2 detects the voltage of the mobile batteries and causes the mobile battery with the largest remaining charge to supply power to the electrical device. When the voltage of this mobile battery falls below a predetermined threshold, the control unit 6e2 causes the mobile battery with the largest remaining charge among the other mobile batteries to supply power to the electrical device. By performing such control, it is possible to replace a mobile battery whose remaining charge has decreased and power supply has been stopped, and by continuing to replace the mobile batteries, it is possible to continuously supply power to the electrical device without stopping the power supply to the electrical device.

[0181] The control unit 6e2 may select a mobile battery to supply power to an electric device based on the installation position of the mobile battery, regardless of the remaining charge of the mobile battery. For example, the control unit 6e2 may supply power to an electric device in order from the mobile battery attached to the leftmost side of the attachment portion 6c3 arranged in the left-right direction.

[0182] The connection wiring 6e3 is a wiring that connects the control unit 6e2 and the outlet 6e4. The connection wiring 6e3 supplies the power output from the control unit 6e2 to the outlet 6e4. The outlet 6e4 is designed to accept an attachment plug of an external electric device, and is shaped according to a general standard.

[0183] The desk 6 of this embodiment includes a battery tray 6c on which the mounting portion 6c3 is provided, and a wiring duct 6d capable of accommodating wiring and fixed to the battery tray 6c to reinforce the battery tray 6c. According to the desk 6 of this embodiment, the battery tray 6c can be reinforced by the wiring duct 6d capable of accommodating wiring. Therefore, it is possible to reinforce the battery tray 6c without providing a reinforcing member for reinforcing the battery tray 6c separately from the wiring duct 6d.

[0184] Fig. 18 is an exploded perspective view of the desk 6 in which the power supply unit 6e described above is replaced with a power supply unit 6g. In the example shown in Fig. 18, a mobile battery attached to the attachment unit 6c3 can be charged. The power supply unit 6g includes a connection wiring 6g1 connected to the attachment unit 6c3, a control unit 6g2 that houses a converter and a control unit, a connection wiring 6g3 that connects the control unit 6g2 and an attachment plug 6g4, and an attachment plug 6g4 that can be inserted into an external outlet.

[0185] The connection wiring 6g1 is connected to the mounting portion 6c3 via a conductive path (not shown) provided in the battery tray 6c. The connection wiring 6g1 is also drawn out from the battery tray 6c, supported by a wiring duct 6d, and connected to the control unit 6g2.

[0186] The control unit 6g2 is housed in the wiring housing space of the wiring duct 6d, for example. This control unit 6g2 includes a converter as described above. This converter converts AC power output from a commercial power source or the like into DC power. This allows charging of the mobile battery.

[0187] In addition, the control unit 6g2 includes a control unit as described above. When multiple mobile batteries are attached to the attachment portion 6c3, the control unit 6g2 controls which mobile battery to supply power to. For example, when multiple mobile batteries are attached, the control unit 6g2 detects the voltage of the mobile batteries and supplies power to the mobile battery with the lowest remaining charge. When the voltage of this mobile battery becomes equal to or higher than a predetermined threshold, the control unit 6g2 supplies power to the mobile battery with the lowest remaining charge among the other mobile batteries.

[0188] The control unit 6e2 may select a mobile battery to supply power to an electrical device based on the installation position of the mobile battery, regardless of the remaining charge of the mobile battery. For example, the control unit 6e2 may supply power sequentially from the mobile battery attached to the leftmost side of the attachment portion 6c3 arranged in the left-right direction.

[0189] The connection wiring 6g3 is a wiring that connects the control unit 6g2 and the attachment plug 6g4. The connection wiring 6g3 supplies power to the control unit 6e2. The attachment plug 6g4 is designed to be pluggable into a socket provided on an external power source, and is shaped in accordance with a general standard.

[0190] As shown in Fig. 18, when a power supply unit 6g capable of charging a mobile battery is provided, it is possible to adopt a configuration in which power cannot be supplied to an electric device from the desk 6. For this reason, as shown in Fig. 18, it is possible to adopt a configuration in which the outlet 6e4 is not provided.

[0191] Although the preferred embodiment of the present invention has been described above with reference to the attached drawings, it goes without saying that the present invention is not limited to the above embodiment. The shapes and combinations of the components shown in the above embodiment are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present invention.

[0192] For example, in the above embodiment, a configuration has been described in which the attachment part is electrically connected by contacting the mobile battery B. However, the present invention is not limited to this. It is also possible to adopt a configuration in which the attachment part and the mobile battery B are electrically connected without contact. Also, a configuration may be adopted in which a mounting part is provided on which the mobile battery B is placed, and the mounting part allows power to be supplied from the mobile battery B to the electrical device. In this way, it is sufficient to provide an installation part on which the mobile battery B, including the attachment part and the mounting part, can be placed, and power can be supplied from the mobile battery B installed on the installation part to the electrical device.

[0193] In the above embodiment, the electrical device is a lighting device, a display, an electric telescopic leg, etc. However, the electrical device in the present embodiment is not limited to this. The electrical device in the present invention also includes a notebook computer, a tablet terminal, a smartphone, a humidifier, a fan, a webcam, etc.
