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 in the middle 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 main body 11.

The plug 14b can be inserted into a socket on the external power source, and is shaped according to a general standard. As shown in Figures 1 and 2, a portion of the connection wiring 14c on the plug 14b side is pulled out from the wagon body 11 as a power cable 14d.

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.

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 external power outlet, 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.

When the plug 14b is inserted into the socket of the external power source and an electrical device is connected to the socket 13b of the power supply unit 13, both charging of the mobile battery B and supply of power to the electrical device are performed.

According to the wagon 1 of this embodiment, a mobile battery B can be installed, and the power of the installed mobile battery B can be supplied to an external electrical device. This makes it 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 via the power cable 14d in order to supply power to the 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.

In addition, in the wagon 1 of this embodiment, the power supply unit 13 is provided with an outlet 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 an outlet in an ordinary 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 an outlet in an ordinary home, office, etc. In this way, according to the wagon 1 of this embodiment, since it is provided with the outlet 13b, the plug of any electrical device can be connected to the outlet 13b, and the user can use any electrical device.

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

The wagon 1 of this embodiment also has casters 12 that can roll on the floor. This allows the casters 12 to roll on the floor, allowing the wagon 1 to be moved smoothly.

The wagon 1 of this embodiment also includes 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 attachment portion 11c. Therefore, by connecting the charging unit 14 to an external power source as needed, it is possible to charge the mobile battery B.

In addition, in this embodiment, the fixture system S1 includes the above-mentioned wagon 1 and a mobile battery B. Such a fixture 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.

Each leg 6a is connected to the underside 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 legs 6a are fixed to the four corners of the top plate 6b in plan view with fasteners (not shown) and the top plate 6b is supported from below by these legs 6a. The upper surface of the 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. The top plate 6b is also provided with four outlets 6e4 (plug-in parts) (described later) provided in the power supply unit 6e.

Figure 16 is a cross-sectional view of the top plate 6b including the battery tray 6c and the wiring duct 6d, looking down from above the top plate 6b. Figure 17 is a cross-sectional view of the top plate 6b including the battery tray 6c and the wiring duct 6d, looking up from below the top plate 6b.

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

The upper tray 6c1 is a plate-like portion slightly larger than the central opening 6b1 formed in the top plate 6b, and its edge is placed on the top surface of the top plate 6b from above. The upper surface of the upper tray 6c1 is provided with a plurality of mounting portions 6c3. 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. The bottom of the lower tray 6c2 is provided with a boss portion 6c5 for screwing a screw. 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 at the same or approximately the same height as the lower surface of the top plate 6b.

The mounting portion 6c3 provided on the upper surface of the upper tray 6c1 has a recess in which a mobile battery can be attached. The diameter of the recess is larger than the diameter of the lower part of the mobile battery, and is capable of accommodating the lower part of the mobile battery. 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.

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 electrical device (not shown) connected to the outlet 6e4.

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.

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

The reinforcing beam 6d2 extends along the longitudinal direction of the top plate 6b and is provided so as to protrude upward from the upper surface of the bottom wall portion 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 portions, and is formed into a so-called hat shape. The edge portions of such a reinforcing beam 6d2 are welded to, for example, the bottom wall portion 6d1, and the center portion is abutted against the lower surface of the lower tray 6c2.

The battery tray 6c is reinforced by the wiring duct 6d by abutting the reinforcing beam 6d2 against the underside of the lower tray 6c2. The reinforcing beam 6d2 has screw insertion holes that are 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 inserting a screw 6f from below into the screw insertion hole and screwing it into the boss portion 6c5.

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 an outlet 6e4 to which an electrical device is connected.

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 pulled out from the battery tray 6c, supported by the wiring duct 6d, and connected to the control unit 6e2.

The control unit 6e2 is housed, for example, in the wiring housing space of the wiring duct 6d. This control unit 6e2 is equipped with an inverter as described above. This inverter converts the DC power output from the mobile battery into AC power. This makes it possible to extract AC power from the outlet 6e4 in the same way as a general commercial power source.

The control unit 6e2 also 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 whose 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.

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, power may be supplied to the electrical device in sequence starting from the mobile battery attached to the leftmost side of the attachment portion 6c3 arranged in the left-right direction.

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 electrical device, and is shaped in accordance with a general standard.

The desk 6 of the present 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 the present 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.

Figure 18 is an exploded perspective view of the desk 6 in which the power supply unit 6e described above has been replaced with a power supply unit 6g. In the example shown in Figure 18, it is possible to charge a mobile battery attached to the mounting part 6c3. The power supply unit 6g includes a connection wiring 6g1 connected to the mounting part 6c3, a control unit 6g2 that houses a converter and a control unit, a connection wiring 6g3 that connects the control unit 6g2 to an attachment plug 6g4, and an attachment plug 6g4 that can be plugged into an external outlet.

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 pulled out from the battery tray 6c, supported by the wiring duct 6d, and connected to the control unit 6g2.

The control unit 6g2 is housed, for example, in the wiring housing space of the wiring duct 6d. This control unit 6g2 is equipped with a converter as described above. This converter converts AC power output from a commercial power source or the like into DC power. This makes it possible to charge the mobile battery.

The control unit 6g2 also includes a control unit as described above. When multiple mobile batteries are attached to the attachment parts 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.

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, power may be supplied in sequence starting from the mobile battery attached to the leftmost side of the attachment portion 6c3 arranged in the left-right direction.

The connection wire 6g3 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 capable of being inserted into a socket provided on an external power source, and is shaped in accordance with general standards.

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 from the desk 6 to electrical devices. Therefore, as shown in FIG. 18, it is possible to adopt a configuration in which no outlet 6e4 is provided.
