The lower plate portion 51 and the upper plate portion 52 are manufactured by processing steel plates. The upper plate portion 52 is formed with a larger planar shape than the lower plate portion 51.

[0030] The lower plate portion 51 has a lower plate portion main body 54 disposed along the lower surface of the top plate 5, and an upright portion 55 protruding upward from the edge portion of the lower plate portion main body 54. The upright portion 55 has a first upright plate portion 551 protruding upward from the edge portion of the lower plate portion main body 54, and a second upright plate portion 552 extending inward (toward the center of the top plate 5 in plan view) from the upper end portion of the first upright plate portion 551.

[0031] The upper plate portion 52 has an upper plate portion main body 56 disposed along the upper surface of the top plate 5, a protruding portion 57 protruding downward from the edge portion of the upper plate portion main body 56, and a surface material 591 provided along the upper surface of the upper plate portion main body 56 and constituting the upper surface of the top plate 5. The protruding portion 57 has a first protruding plate portion 571 protruding downward from the end portion of the upper plate portion main body 56, a second protruding plate portion 572 extending inward from the lower end portion of the first protruding plate portion 571, and an end cover material 592 covering the first protruding plate portion 571 from the front side. The first protruding plate portion 571 has a dimension in the vertical direction smaller than that of the first upright plate portion 551. In this embodiment, the surface material 591 is provided along the upper surface of the upper plate portion main body 56, but the surface material 591 may not be provided and the upper surface of the upper plate portion main body 56 may constitute the upper surface of the top plate 5.

[0032] When the upper plate portion 52 is disposed on the lower plate portion 51, the protruding portion 57 of the upper plate portion 52 is disposed outside the upright portion 55 of the lower plate portion 51 (on the side facing outward of the top plate 5 in plan view). The upper plate portion main body 56 overlaps on the second upright plate portion 552, the first protruding plate portion 571 is disposed at an interval outside the first upright plate portion 551, and the second protruding plate portion 572 is disposed outside the first upright plate portion 551 at a position above the lower plate portion 51.

The reinforcing member 53 is arranged in a posture extending in the entire width direction of the top plate 5 with the C-shaped cross section opening upward. The reinforcing member 53 is provided to increase the strength of the top plate 5. As described above, the top plate 5 of the present embodiment has a long shape extending in the width direction. Therefore, when a user touches the top plate 5 with their hand or an article is placed on the top plate 5, the central portion in the width direction of the top plate 5 tends to deform downward and bend. By arranging the reinforcing member 53 to extend in the entire width direction of the top plate, the strength of the top plate 5 is increased, and the above-described deformation can be suppressed.

[0035] The reinforcing member 53 has a bottom plate portion 531 arranged along the upper surface of the lower plate portion 51, a first side plate portion 532 extending upward from the rear end portion of the bottom plate portion 531, a first folded-back plate portion 533 extending forward from the upper end portion of the first side plate portion 532, a second side plate portion 534 extending upward from the front end portion of the bottom plate portion 531, and a second folded-back plate portion 535 extending rearward from the upper end portion of the second side plate portion 534. The upper plate portion main body 56 is placed on the first folded-back plate portion 533 and the second folded-back plate portion 535.

[0036] The reinforcing member 53 is provided at least near the front end portion 5a (the end portion on the chair 3 side) of the top plate 5. In FIG. 5, the reinforcing member 53 provided near the front end portion 5a of the top plate 5 is shown. The second side plate portion 534 is arranged behind the first standing plate portion 551. A plurality of reinforcing member holes 531a penetrating vertically are formed at intervals in the width direction in the middle portion in the front-rear direction of the bottom plate portion 531. Nuts 536 are joined above each of the plurality of reinforcing member holes 531a on the bottom plate portion 531. A lower plate hole 54a penetrating vertically is formed at a position directly below the reinforcing member hole 531a in the lower plate portion main body 54. A bolt 44 described later can be fastened to the nut 536 from the lower side of the lower plate portion 51 through the lower plate hole 54a and the reinforcing member hole 531a.

[0037] The socket unit 4 has a block-shaped outer shape. The socket unit 4 has a power supply connection part 41 for supplying power to an electronic device used on the top plate 5. The socket unit 4 is not limited to the power supply connection part 41. It may also be used as a connection part for a USB terminal, a LAN terminal, etc., and may have connection parts for a plurality of different uses respectively. The socket unit 4 is provided at the front side portion of the lower surface of the top plate 5. The socket unit 4 is disposed at a position rearward of the front end portion (the end portion on the chair side) of the top plate 5. In the present embodiment, the socket unit 4 is provided along the lower surface of the lower plate portion main body 54, and is disposed at a rear side portion (the portion away from the chair 3) of the second protruding plate portion 572 located at the front end portion of the top plate 5. In the present embodiment, the socket unit 4 is disposed about 15 mm rearward of the front end portion 5a of the top plate 5.

[0038] The socket unit 4 has a main body portion 42 in which the power supply connection part 41 is accommodated, and a mounting plate portion 43 that protrudes laterally from the upper end portion of the main body portion 42. A mounting hole portion 43a through which a bolt 44 can be inserted is formed in the mounting plate portion 43. The socket unit 4 is arranged such that the mounting hole portion 43a overlaps the lower side of the lower plate hole portion 54a of the top plate 5. In the state arranged in this way, the socket unit 4 is fixed to the reinforcing member 53, that is, the top plate 5, by fastening the bolt 44 to the nut 536 through the mounting hole portion 43a, the lower plate hole portion 54a, and the reinforcing member hole portion 531a.

[0039] As shown in FIG. 2, two socket units 4 are provided at intervals in the width direction at the middle portion in the width direction of the top plate 5. The socket units 4 are arranged one by one at positions corresponding to between the adjacent chairs 3 in the width direction. The socket units 4 are provided so as not to contact the chair 3 even when the seating portion 32 of the chair 3 has moved to the side of the furniture 2 with the top plate.

[0040] In the furniture unit 1 according to the present embodiment, the power outlet unit 4 attached to the lower surface of the top plate 5 is disposed at a position farther from the chair 3 than the end of the top plate 5 on the chair 3 side. As a result, as shown in FIG. 4, when the user sits on the seating portion 32 with the legs 12 placed below the top plate 5, the user's legs are less likely to come into contact with the power outlet unit 4, and the user can sit on the seating portion 32 without taking an awkward posture so as not to contact the power outlet unit 4. In particular, when the thickness dimension of the top plate 5 is small, the power outlet unit cannot be accommodated inside the top plate. In such a case, even if the power outlet unit 4 is provided under the top plate 5, the user's legs are less likely to come into contact with the power outlet unit 4 as described above, and the user can sit on the seating portion 32 without taking an awkward posture so as not to contact the power outlet unit 4.

[0041] Further, in the furniture unit 1 according to the present embodiment, there is a step 58 on the lower surface of the top plate 5, and the power outlet unit 4 is attached to the lower surface of the lower plate main body portion on the lower side. With such a configuration, the power outlet unit 4 is located below the lower surface of the second protruding plate portion 572 near the end on the chair 3 side on the lower surface of the lower plate main body portion away from the end on the chair 3 side of the top plate 5. For this reason, the user's legs are less likely to come into contact with the power outlet unit 4, and the user can sit on the seating portion 32 without taking an awkward posture so as not to contact the power outlet unit 4, and the visibility of the power outlet unit 4 from the chair 3 side can be improved.

[0042] Further, in the furniture unit 1 according to the present embodiment, the top plate 5 is formed of a steel plate. With such a configuration, it is easy to form the protruding portion 57 of the upper plate portion 52 and the standing portion 55 of the lower plate portion 51. It is easy to perform processing such as the step 58 on the lower surface of the top plate 5.

[0043] Further, in the furniture unit 1 according to the present embodiment, the power outlet unit 4 is fixed to a reinforcing member 53 provided on the top plate 5 and extending in the entire width direction of the top plate 5. By adopting such a configuration, the power socket unit 4 can be firmly fixed to the top plate 5. Also, the installation position of the power socket unit 4 in the width direction can be adjusted within the length range of the reinforcing member 53. In addition, by providing the reinforcing member 53 between the upper plate portion 52 and the lower plate portion 51, the top plate 5 can be formed thinner.

[0044] (Second Embodiment) Next, other embodiments will be described with reference to the accompanying drawings. Members and parts that are the same as or similar to those in the above-described first embodiment will be described using the same reference numerals, and descriptions thereof will be omitted. Configurations different from the embodiments will be described. As shown in FIG. 6, in the furniture unit 1B of the second embodiment, two furniture items 2, 2 with top plates are arranged adjacent to each other in the width direction. In the second embodiment, a power socket unit 4B is provided which is arranged so as to straddle the top plates 5 of two adjacent furniture items 2 in the width direction and is fixed to each of the two adjacent top plates 5 in the width direction.

[0045] In the furniture unit 1B according to the second embodiment, when the furniture units 1B are arranged in the width direction, the power socket unit 4B can be arranged at the widthwise end portions of each of the furniture items 2 with top plates. Also, the power socket unit 4B can connect the furniture items 2 with top plates adjacent to each other in the width direction.

For example, in the above embodiment, the seating portion 32 of the chair 3 is configured to be movable in the front-rear direction with respect to the top plate 5 by the leg members 34 of the chair lower structure 31 rotating around the axis of the shaft portion 331 in the width direction. In contrast, the seating portion 32 may be configured to be slidable in the front-rear direction with respect to the top plate 5. For example, the seating portion 32 and the leg members 34 may be integrated, and the integrated seating portion 32 and leg members 34 may be slidably supported in the front-rear direction by a grounding portion 33 fixed to the floor surface 11. Further, the grounding portion 33 and the leg members 34 may be integrated, and the seating portion 32 may be slidably supported in the front-rear direction by the integrated grounding portion 33 and leg members 34. Also, the seating portion 32 may be rotatably supported around an axis extending in the vertical direction. For example, the seating portion 32 may be attached on a column portion (chair lower structure) extending in the vertical direction supported by the floor surface and may be configured to be rotatable by a predetermined angle around the axis of the column portion. In such a case, the column portion supports the central portion in the width direction of the seating portion 32. By the seating portion 32 rotating around the axis of the column portion, either one side in the width direction of the seating portion 32 at the trailing edge portion 321a (the edge portion on the side of the furniture 2 with a top plate) with respect to the column portion moves forward with respect to the top plate 5, and the other side moves backward. In other words, by the seating portion 32 rotating around the axis of the column portion, either one side in the width direction of the seating portion 32 at the trailing edge portion 321a moves away from the front end portion 5a of the top plate 5, and the other side approaches it.

[0047] In the above embodiment, three chairs 3 are provided for one furniture 2 with a top plate, but the number of chairs 3 may be appropriately set. The dimensions of each member such as the thickness dimension of the top plate may be appropriately set.

[0048] In the above-described embodiment, there is a step 58 on the lower surface of the top plate 5, and the socket unit 4 is attached to the lower surface of the lower plate body 54 which is below the step 58. However, the lower surface of the top plate 5 may be flat, and the socket unit 4 may be attached to such a flat lower surface. Further, instead of the step 58 on the lower surface of the top plate 5, as shown in FIG. 8, an inclined surface 59 that inclines downward toward the front in a side view from the width direction may be formed, and the socket unit 4 may be attached to a portion on the back side (rear side) of the inclined surface 59 on the lower surface of the top plate 5.

[0049] In the above-described embodiment, the top plate 5 is formed of a steel plate, but it may be formed of a material other than the steel plate.

[0050] Also, in the furniture unit 1 according to the present embodiment, the socket unit 4 is fixed to a reinforcing member 53 provided on the top plate 5 and extending in the entire width direction of the top plate 5. On the contrary, the socket unit 4 may be fixed to a portion without the reinforcing member 53, or may be fixed to the top plate 5 without the reinforcing member 53. When the reinforcing member 53 is provided, it may be in a form other than the above. For example, although the reinforcing member 53 is provided between the lower plate portion 51 and the upper plate portion 52, it may be provided at the lower part of the top plate 5 and may constitute the lower surface of the top plate 5.

[0051] Also, in the above-described first embodiment, socket units 4 are provided one by one at positions corresponding to between the chairs 3 adjacent in the width direction. In the above-described second embodiment, the socket unit 4 is provided so as to connect the top plates 5 adjacent in the width direction. The position where the socket unit 4 is provided may be set as appropriate. For example, as in the furniture unit 1C shown in FIG. 7, two socket units 4 may be provided at positions corresponding to between the chairs 3 adjacent in the width direction so that a user seated on each chair 3 can use the power supply connection portion 41 of the socket unit 4.
