The moving-side top plate 20 can be operated from the front side of the cart 2 by placing an electronic device such as a personal computer (reference numeral P in FIG. 1) on the upper surface 20a, and is placed on the moving-side top plate 20. The rear side outer peripheral portion 20c (FIG. 1) protrudes upward so that the electronic device does not fall to the rear side.

  An insertion hole 20d is provided in a predetermined position on the moving-side top plate 20 so as to penetrate in the thickness direction, whereby an output-side outlet (not shown) of the power receiving device 40 can be connected from the lower surface 20b side to the top. It is inserted toward the upper side of the plate.

Furthermore, a pair of cart guide members 16, 16 that guide the cart 2 when the cart 2 is moved from the lower surface 11 b to move the cart 2 to enter the concave portion 29 on the lower surface 11 b of the fixed top plate 11. (Guide means) is provided.
The cart guide members 16, 16 are a pair of rod-like members disposed on both sides of the cart 2 when the fixed-side top plate 11 enters the recess 29, and are bent in the middle of the extending direction. As shown in FIG. 3, the pair of cart guide members 16, 16 are separated from each other in the lateral width of the cart 2 at the front end 16 a that is the front side, that is, the lateral width between the side frames 23, 23. It is larger than the size and gradually decreases toward the rear end 16c, becomes substantially equal to the lateral width of the cart 2 at the bending point 16b, and extends from the proximal end 16a to the distal end 16c.

  For this reason, even if the position of the cart 2 is shifted when the cart 2 is moved and the fixed-side top plate 11 of the table 1 enters the recess 29, the rear column 232 of the cart 2 abuts against the cart guide member 16. Thus, the cart 2 is guided to a correct position in the left-right direction. Further, when the cart 2 is moved toward the table 1 to a predetermined position, the edge portion 11d of the fixed-side top plate 11 of the table 1 abuts against the stopper 52 and the movement is restricted.

Next, the power supply device 10 including the power supply device 30 provided on the table 1 and the power reception device 40 provided on the cart 2 will be described in detail with reference to the drawings.
As shown in FIG. 2, the power supply device 10 brings a power feeding side coil 31 provided on the table 1 and a power receiving side coil 41 provided on the cart 2 close to each other, and receives power by electromagnetic induction generated by a current of the power feeding side coil 31. Non-contact power feeding is performed by generating a current in the side coil 41.

  As shown in FIGS. 1, 5, and 7, the power supply device 30 includes a cover body 33 in which a power supply side coil 31 (power supply unit) including a frequency converter 35 and a switch unit 32 (switch mechanism) have a thin box shape. The power supply side coil 31 is connected to an outlet (not shown) provided on the fixed side top plate 11 of the table 1 via a power cable 34 (see FIG. 1). In FIG. 1, the frequency converter 35 is housed in a cover different from the cover body 33.

The cover body 33 has an open top surface and is fixed at a predetermined position on the bottom surface 11 b of the fixed-side top plate 11. The cover body 33 is provided with an opening 33a into which a convex portion 48 of a power receiving device 40 on the cart 2 side, which will be described later, can enter.
The power supply side coil 31 is provided so as to be exposed on the lower surface of the cover body 33 with the coil power supply surface 31a facing downward. At this time, the surface direction of the coil power supply surface 31 a is a horizontal direction and is flush with the lower surface of the cover body 33.

As shown in FIG. 5 and FIG. 6, the switch portion 32 has a working end of the rotation operation plate 322 when the rotation operation plate 322 provided with the spring member 321 rotates against the bias of the spring member 321. The switch 323 is turned on at 322a.
The rotation operation plate 322 has a substantially fan-shaped rotation plate 322A in plan view that rotates about a rotation axis 322c in a direction orthogonal to the bottom surface 33b of the cover body 33, and one end (base) of the rotation plate 322A in the circumferential direction. At the end 322b), an overhanging piece 322B protruding outward in the radial direction of the rotating plate 322A is provided. Further, the projecting piece 322B was urged to the outer peripheral part forming the arc of the rotary operation plate 322 in a state where the projecting piece 322B was disposed at the position of the opening 33a of the cover body 33, that is, the position where the approach path of the convex portion 48 was blocked. The spring member 321 is attached, that is, the rotation operating plate 322 is pressed against the protruding piece 322B by the convex portion 48 entering the cover body 33 from the opening 33a, thereby resisting the bias of the spring member 321. Thus, it rotates in one direction (in the opposite direction to the clockwise direction in the figure) around the rotation shaft 322c, and moves to the position of the two-dot chain line in FIG.

  The switch 323 is a lever-type switch, and the lever portion 323a can selectively take an on / off position depending on the position of the working end 322a of the rotary operation plate 322. That is, the switch 323 is in an off state when the rotation operation plate 322 is not rotating, and the lever portion 323a is pressed by the action end 322a by the rotation of the rotation operation plate 322 to be in an on state. Is flowing.

  Next, as shown in FIGS. 4, 7, and 8 (a), the power receiving device 40 includes a power receiving side coil 41 (power receiving unit) including a rectifier 41 b, and a voltage converter 43 in the power receiving side coil 41. And a battery 42 connected to each other via a power supply cable for an electronic device used on the moving top plate 20 on the output side of the battery 42. (Not shown) is connected. In addition, in Fig.8 (a), the code | symbol 49 has shown the heat sink.

  The power receiving side coil 41 is exposed on the upper surface 44b of the cover body 44 with the coil power receiving surface 41a facing upward, and the coil 2 is the coil power feeding surface of the power feeding side coil 31 in a state where the cart 2 is positioned at the power feeding position R with respect to the table 1. It arrange | positions in the position which opposes 31a with a space | interval.

  As shown in FIG. 7, the battery 42 includes a battery main body 421, a charge control unit 422 that controls charge input from the power receiving side coil 41, and an output control unit 423 that controls a voltage output from the battery main body 421. And.

As shown in FIG. 8B, on the front side surface 44b of the cover body 44, an energization state display unit 46A for displaying “charging” in the non-contact power supply state and a “remaining battery amount” in the battery 42 are displayed. A display unit 46 including a charge state display unit 46B is provided (see FIGS. 1 and 2). The energization state display unit 46A and the charge state display unit 46B use light emitting diodes (LEDs), and are connected to the voltage converter 43 and the charge control unit 422, respectively, and are lit according to received signals. And this display part 46 forms the inclined surface in which a display surface faces diagonally upward.
Note that, as described above, in the state where the cart 2 and the table 1 are combined at the power feeding position R, the display unit 46 is in front of the edge portion 11d of the fixed-side top plate 11, that is, in a plan view. It is located in the part which does not overlap with the fixed side top plate 11.

  In the power supply device 10 configured as described above, when the power feeding side coil 31 and the power receiving side coil 41 are brought close to each other, the switch 323 of the switch unit 32 is turned on in the power feeding device 30, for example, AC 100V electricity is supplied by the DC power source. It is converted to DC 24V and flows to the power supply side coil 31. Then, current is generated in the power receiving side coil 41 by electromagnetic induction caused by the current in the power feeding side coil 31, and non-contact power feeding is performed. Further, in the power receiving device 40, the voltage supplied by the power receiving side coil 41 is converted to 17V DC by the voltage converter 43 and charged to the battery body 421. At the time of output, the voltage is converted to 15V DC by the output control unit 423, and the power cable Will be output via.

Next, the operation of supplying power to the power receiving device 40 of the cart 2 and the operation of the above-described fixture system will be described in detail based on the drawings.
As shown in FIGS. 1 to 4, when the battery 42 mounted on the cart 2 is charged, that is, when electricity is supplied to the power receiving device 40, the cart 2 is disposed at a predetermined power feeding position R on the table 1. Specifically, the cart 2 is moved so as to be close to the table 1 and is moved into the accommodating portion 13 of the table 1. At this time, by causing the cart 2 to enter between the pair of cart guide members 16, 16, the cart 2 is guided along the cart guide members 16, 16 to a predetermined power feeding position R.

  When the cart 2 is disposed at the power feeding position R, the power receiving side coil 41 of the power receiving device 40 of the cart 2 approaches the power feeding side coil 31 of the power feeding device 30 of the table 1, and electricity flows through the power feeding device 30. That is, as shown in FIGS. 5 and 6, when the cart 2 is disposed at the power feeding position R, the convex portion 48 provided on the cover body 44 of the power receiving device 40 of the cart 2 is the cover body of the power feeding device 30. It enters the opening 33a of 33. Then, the projecting portion 322B of the switch portion 32 is pressed by the convex portion 48, whereby the rotation operating plate 322 resists the bias of the spring member 321 in one direction around the rotation shaft 322c (clockwise in the figure). The lever portion 323a is pressed by the action end 322a due to the rotation of the rotating operation plate 322, and the lever portion 323a is turned on, so that a current flows through the power supply side coil 31.

Next, since the power feeding side coil 31 and the power receiving side coil 41 are close to each other, when a current flows through the power feeding side coil 31, a current is generated in the power receiving side coil 41 due to electromagnetic induction caused by the current in the power feeding side coil 31. Thus, non-contact power feeding is performed. Further, in the power receiving device 40, the voltage supplied by the power receiving coil 41 is converted to an appropriate voltage via the voltage converter 43 and charged to the battery body 421, and is converted into a DC voltage by the output control unit 423 at the time of output. Thus, the non-contact power supply for supplying power to the power receiving device 40 of the cart 2 is performed.
In this way, it is possible to secure the power source of the electronic equipment to be used from the power cable wired on the moving side top plate 20 of the cart 2 by non-contact power feeding, and after charging the battery 42, the cart 2 is placed on the table. It is possible to move to a place away from 1 and connect the electronic device to the battery 42 on the moving side top plate 20 to use it for a long time.

In addition, when the cart 2 and the table 1 are in a state where the predetermined power feeding position R is established, the power receiving side coil 41 provided in the cart 2 is disposed opposite to the power feeding side coil 31 provided in the table 1, Since non-contact power feeding is performed, it is possible to save the trouble of inserting the power cord into the outlet in the cart 2, and it is possible to eliminate the need for wiring many power cables on the floor surface.
In addition, since the power supply side coil 31 is provided on the table 1 placed on the floor surface F, it is easy to avoid placing the power feeding unit directly on the floor surface F and placing the table 1 indoors. In addition, the power feeding unit can be provided at a low cost. Moreover, since it is not necessary to process the floor structure, there is an advantage that it is possible to avoid that the use in the office is limited.
Furthermore, power can be supplied while at least a part of the cart 2 is accommodated in the accommodating portion 13 of the table 1, the area occupied by the fixture can be reduced, and the space can be effectively utilized.

  Furthermore, since the cart 2 can be guided to the power feeding position R where power can be fed by the cart guide members 16, 16, the positioning of the power feeding side coil 31 and the power receiving side coil 41 can be easily performed. The cart 2 for contact power feeding can be efficiently moved. In addition, the cart guide member 16 that hangs down is housed in the storage portion 13 of the table 1, and is hardly exposed to the outside, so that the appearance as a fixture can be improved.

Further, the display surface of the display unit 46 indicating the power supply operation state is formed with an inclined surface directed toward the line of sight of the user who works on the display unit 46 side (front side) with respect to the cart 2. Since the display part 46 is easy to see, visibility can be improved and usability is further improved.

Moreover, when the cart 2 and the table 1 are combined at the predetermined power feeding position R, the charging state of the display unit 46 of the power receiving device 40 provided integrally with the cover body by the user of the cart 2 in the energized state by power feeding. The remaining state of the battery 42 can also be confirmed visually by the display unit 46B. And since the charging state display part 46B is located ahead of the edge part 11d of the fixed side top plate 11 in the state combined in the electric power feeding position R, the fixed side top plate 11 located above the power receiving apparatus 40 is shown. Visibility is not obstructed by this, and visibility can be secured.
Further, even when the cart 2 is moved to a place away from the table 1 while the battery 42 provided in the power receiving device 40 is charged, the remaining state of the battery 42 can be confirmed by the charge state display unit 46B. .

  As described above, in the fixture system according to the present embodiment, in the state where the cart 2 and the table 1 are at the predetermined power feeding position R, the display disposed on the side surface of the power receiving device 40 integrally provided with the power receiving side coil 41. There is an advantage that visibility can be ensured without the field of view being obstructed by the fixed side top plate 11 positioned above the power receiving device 40. Therefore, it is possible to improve the usability and appearance as a space in which the table 1 and the cart 2 are used.

As mentioned above, although the embodiment of the furniture system by this invention was described, this invention is not limited to said embodiment, In the range which does not deviate from the meaning, it can change suitably.
For example, in the present embodiment, the power supply device 10 using electromagnetic induction provided with the power supply side coil 31 and the power reception side coil 41 is used as non-contact power supply, but is limited to such a power transmission method using non-radiation type electromagnetic induction. For example, a non-radiation type magnetic resonance method or a radiation type electromagnetic wave (microwave power transmission) method may be employed. Further, instead of non-contact power feeding, contact power feeding may be employed.

  In the present embodiment, an example in which the cart 2 (movable fixture) is used in a place away from the table 1 (fixed fixture) is used. However, the present invention is not limited to this. Of course, it is also possible to use it in a state of being combined at the charging position R.

  Furthermore, in this Embodiment, it is set as the fixture system by the combination of the cart 2 which has the recessed part 29, and the table 1, However, It is not limited to such a form. For example, a top plate-like extending member that protrudes horizontally from a fixed fixture such as a shelf may be used as the fixed side top plate. In this case, a moving fixture having a configuration in which the concave portion 29 is not provided may be used, and the coil power receiving surface 41a of the power receiving side coil 41 may be exposed on the upper surface of the moving side top plate.

Furthermore, in the present embodiment, as the display unit 46, the energization state display unit 46A and the charge state display unit 46B are provided, but the charge state display unit 46B may be omitted.
And in this Embodiment, although the display part 46 forms the inclined surface in which a display surface faces diagonally upwards, it is not restrict | limited to an inclined surface, A display surface is a perpendicular surface orthogonal to a horizontal surface. There may be.

Further, the configuration of the table 1 and the cart 2, such as the shape and size, the usage application of the cart 2, the cart guide member 16 and the like are not particularly limited.
Furthermore, the positions of the power supply device 10, the power supply device 30, and the power receiving device 40 can be set as appropriate according to conditions such as the shape of the fixed fixture and the mobile fixture.
