Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the configuration as disclosed in Patent Document 1, since the wiring connection part is provided on the side surface of the support column, the connection port faces sideways (forward). For this reason, it is difficult to visually recognize the connection port, and it may be difficult to insert and remove wiring into and from the connection port. An object of the present invention is to provide a chair that can enhance the visibility of a connection port of a wiring connection part and easily and surely perform insertion and removal of wiring.

Means for Solving the Problems

[0005] To achieve the above object, a chair according to an aspect of the present invention includes a seating surface facing upward, and an upward-facing surface formed on a side of the seating surface and facing upward, a base member installed on a floor surface, a table top plate arranged above the base member with a space therebetween and having a top surface facing upward, a support member extending upward from the base member and supporting the table top plate, and a wiring connection part provided on the upward-facing surface and having a connection port opening upward.

[0006] In this way, by providing a wiring connection portion having a connection port that opens upward on the upward-facing surface formed on the side of the seating surface, the connection port can be easily visually recognized. Therefore, it is possible to insert and remove the wiring into and from the connection port while visually recognizing the connection port. As a result, the visibility of the connection port of the wiring connection portion can be enhanced, and it becomes possible to easily and surely insert and remove the wiring.

[0007] In the chair according to one aspect of the present invention, the table top may be supported by the support member so as to be displaceable between a first state in which at least a part of the table top overlaps the upward-facing surface in plan view and a second state in which the table top is located closer to the seating surface side than the first state. According to this configuration, in the first state, at least a part of the table top overlaps the upward-facing surface in plan view, and even when the table top is located above the wiring connection portion, since the connection port faces upward on the upward-facing surface, the visibility of the connection port can be easily ensured. Also, since at least a part of the table top overlaps the upward-facing surface in plan view, the table top is located on the side of the seating surface. Therefore, the accessibility of the user to the seating surface is enhanced. Also, in the first state, articles such as the user's belongings can be placed on the top surface of the table top. At that time, since the table top is located on the side of the seating surface, it is possible to suppress the articles placed on the top surface from disturbing the user seated on the seating surface. Also, in the second state, since at least a part of the table top is located closer to the seating surface side than the first state, it overlaps the seating surface in plan view. As a result, at least a part of the table top is located in front of the user as seen from the user seated on the seating surface. Therefore, in the second state, it is easy for the user to perform various operations on the top surface of the table top.

[0008] In the chair according to one aspect of the present invention, the table top may be supported by the support member so as to be rotatable about an axis along the vertical direction and displaceable between the first state and the second state. According to this configuration, the table top plate can be easily displaced from the first state to the second state, and the connection port can be placed in a visible state.

[0009] In the chair according to one aspect of the present invention, in the first state, the entire table top plate may overlap the base member in plan view. According to this configuration, in the first state, since the entire table top plate overlaps the base member in plan view, the table top plate does not protrude outward from the base member, and interference with the surroundings can be avoided. Even in this state, since the connection port faces upward on the upward-facing surface, the visibility of the connection port can be easily ensured.

[0010] In the chair according to one aspect of the present invention, the wiring connection portion may be arranged so as to overlap the table top plate in the first state in plan view. According to this configuration, in the first state, the wiring connection portion is covered from above by the table top plate. Thereby, when a beverage or the like placed on the top surface of the table top plate by the user spills in the first state, it is possible to suppress the liquid from directly falling on the wiring connection portion. Even in this state, since the connection port faces upward on the upward-facing surface, the visibility of the connection port can be easily ensured.

[0011] In the chair according to one aspect of the present invention, the wiring connection portion may be arranged so as to be laterally displaced with respect to the table top plate in the second state in plan view. According to this configuration, the wiring connection portion is laterally displaced with respect to the table top plate in the second state in plan view, so that the wiring connection portion is not covered from above by the table top plate and is exposed upward. Thereby, the visibility of the connection port is further enhanced.

[0012] In the chair according to one aspect of the present invention, the base member may include a plate-like member having the upward-facing surface, and the wiring connection portion may be provided on the plate-like member. According to this configuration, by providing a plate-like member having an upward-facing surface on the side of the seating surface, the seating surface and the upward-facing surface can be clearly demarcated. As a result, it becomes easier for a user sitting on the seating surface to visually recognize the wiring connection portion provided on the upward-facing surface. Also, by providing the wiring connection portion on the plate-like member, the wiring connection portion can be firmly supported.

[0013] In the chair according to one aspect of the present invention, the wiring connection portion may be arranged at an end portion on the side spaced apart from the seating surface in the width direction on the upward-facing surface. According to this configuration, a wide space on the upward-facing surface can be secured and effectively utilized between the wiring connection portion and the seating surface. Also, since the wiring is connected to the wiring connection portion at the end of the upward-facing surface, the wiring is less likely to interfere with a user sitting on the seating surface.

Effects of the Invention

[0014] According to one aspect of the present invention, the visibility of the connection port of the wiring connection portion can be enhanced, and the insertion and removal of the wiring can be performed easily and reliably.

[0016] Hereinafter, embodiments for carrying out the chair according to the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to only this embodiment.

[0017] FIG. 1 is a perspective view showing the overall configuration of a chair 1 according to an embodiment of the present invention. FIG. 2 is a perspective view showing the chair body 2 of the chair 1. FIG. 3 is a front view of the chair body 2. FIG. 4 is a plan view of the chair body 2. As shown in FIG. 1, the chair 1 includes a chair body 2 and a panel member 9. As shown in FIGS. 2 to 4, the chair body 2 mainly includes a base member 3, a support member 5, a table top 6, a backrest 7, and a wiring connection portion 8.

[0018] The base member 3 is installed on the floor surface F. The base member 3 has a seating surface 101 facing upward and an upward surface 102 formed on the side of the seating surface 101 and facing upward. In the present embodiment, the base member 3 has a rectangular shape in plan view, and the seating surface 101 and the upward surface 102 are arranged along the long side direction of the base member 3. In the following description, the long side direction of the base member 3 in which the seating surface 101 and the upward surface 102 are arranged is defined as the width direction Dw, and the direction orthogonal to the width direction Dw in the horizontal plane is defined as the front-rear direction Dfr. Note that the plan view shape of the base member 3 may be circular, elliptical, polygonal, or the like.

[0019] The base member 3 includes a support structure 30, a seating member 40, and a plate-like member 45. As shown in FIGS. 2 and 3, the support structure 30 is installed on the floor surface F. The support structure 30 has a base portion 31 and support legs 32.

[0020] FIG. 5 is a view showing the configuration of the base portion 31 of the chair body 2, and is a cross-sectional view taken along the line A-A in FIG. 4. The base portion 31 is generally in the shape of a substantially rectangular parallelepiped box, and is constituted by, for example, panel materials made of a wood-based material. As shown in FIG. 5, the base portion 31 includes a bottom plate 33, side plates 34, and an upper plate 35. The bottom plate 33 is disposed at a distance above the floor surface F. The bottom plate 33 is provided along a horizontal plane intersecting the vertical direction Dv. The bottom plate 33 has a rectangular shape in plan view. The side plates 34 are provided along the four sides of the bottom plate 33. The side plates 34 stand upright upward from the four sides of the bottom plate 33 respectively. The upper plate 35 is provided on the side plates 34. The upper plate 35 is disposed at a distance above the bottom plate 33. The upper plate 35 is provided along a horizontal plane and forms a base upper surface 31t facing upward.

[0021] The legs 32 extend downward from the base portion 31. The legs 32 are provided, for example, at the four corners of the base portion 31. By the legs 32 standing on the floor surface F, the base portion 31 is supported above the floor surface F. At the lower ends of the legs 32, an adjuster for height adjustment, a caster roller (both not shown) that can roll on the floor surface F may be provided.

[0022] Such a support structure 30 includes a first support portion 36, a second support portion 37, and a partition wall 38. The first support portion 36 is provided on one side in the width direction Dw on the upper plate 35 of the base portion 31. The first support portion 36 is formed in a part of the upper plate 35. The first support portion 36 has a first support surface 36f. The first support surface 36f is formed by a part of the base upper surface 31t and faces upward. The first support surface 36f supports the seating member 40 from below.

[0023] The second support portion 37 is provided side by side on the upper plate 35 of the base portion 31 on the other side (one side in the horizontal direction) of the first support portion 36 in the width direction Dw. The second support portion 37 has a second support surface 37f located below the seating surface 101. The second support surface 37f is formed by the upper surface of the plate body 37d. In a portion surrounding the outer periphery of the second support surface 37f, the side plate 34 extends upward from the upper surface 31t of the base portion. The plate body 37d is supported from below by the upper end of the raised portion member 37k provided so as to rise upward from the upper surface 31t of the base portion and the upper end of the side plate 34. Thereby, the plate body 37d is disposed above the upper surface 31t of the base portion. The second support surface 37f is formed by the upper surface of the plate body 37d. The second support surface 37f (plate body 37d) is provided at a position different in the width direction Dw from the portion of the upper surface 31t of the base portion that constitutes the first support surface 36f. In this way, the first support surface 36f is located below the second support surface 37f.

[0024] The seating member 40 is placed on the first support surface 36f. The seating member 40 is provided so as to cover the entire first support surface 36f. The seating member 40 has a predetermined thickness in the vertical direction Dv. The upper surface of the seating member 40 is located above the second support surface 37f in the vertical direction Dv. The seating member 40 is made of a material such as sponge and is elastically deformable. As shown in FIG. 2, the front end portion 40a of the seating member 40 is curved obliquely downward toward the front.

[0025] As shown in FIG. 5, the partition wall 38 is provided between the first support portion 36 and the second support portion 37 in the width direction Dw. The partition wall 38 protrudes above the first support surface 36f and the second support surface 37f. The upper end of the partition wall 38 is provided at substantially the same height as the upper surface of the seating member 40. The end portion 40s of the seating member 40 on the second support portion 37 side abuts against the partition wall 38. FIG. 6 is a perspective view showing the second support surface 37f and the step portion D provided on the base portion 31. At least the upper surface of the seating member 40 and the partition wall 38 are covered with a skin material 39 made of cloth, a vinyl-based material, or the like. In the present embodiment, the skin material 39 integrally covers the entire side surface of the base 31 in addition to the upper surface of the seating member and the partition wall 38. As a result, as shown in FIGS. 5 and 6, a stepped portion D covered with the skin material 39 together with the seating member 40 is provided on the second support surface 37f side with respect to the first support surface 36f. The seating surface 101 is formed by covering the upper surface of the seating member 40 with the skin material 39. The edge 39e of the skin material 39 is located on the second support surface 37f and is covered with a plate-like member 45 (see FIG. 7).

[0026] As shown in FIGS. 3 and 5, the plate-like member 45 is placed on the second support surface 37f. The plate-like member 45 is provided on the side of the seating member 40. The plate-like member 45 is provided along a horizontal plane, and its upper surface forms an upward-facing surface 102. The upward-facing surface 102 and the seating surface 101 are provided at substantially the same height and are continuous in the width direction Dw. The upward-facing surface 102 and the seating surface 101 may have different heights in the vertical direction Dv, but the height difference between the upward-facing surface 102 and the seating surface 101 is preferably, for example, within 10 cm.

[0027] The plate-like member 45 is formed of a material different from that of the seating member 40 and the skin material 39. The plate-like member 45 uses the upward-facing surface 102 as an article placement surface and is formed of a material harder than the seating member 40 constituting the seating surface 101, such as a wood-based material, a resin-based material, or a metal material. In addition, in the present embodiment, since the plate-like member 45 functions as the opening surface of the wiring connection portion 8, it is more preferable to use a material having insulation properties among the above materials. The plate-like member 45 covers the entire second support surface 37f. In the present embodiment, "plate-like" refers to a shape in which the minimum dimension in the width direction Dw and the minimum dimension in the front-rear direction Dfr are larger than the maximum dimension in the vertical direction Dv. Therefore, the plate-like member 45 is not limited to having a flat upward-facing surface 102 and may have a stepped surface or a curved surface. Also, the upward-facing surface 102 is not limited to being flush with the seating surface 101.

[0028] As shown in FIG. 3, the support member 5 extends upward from the upper surface 102. The support member 5 supports the table top 6 described later. The support member 5 supports the table top 6 so as to be rotatable about an axis along the vertical direction Dv. The support member 5 is disposed within the range of the base member 3 in a plan view. That is, the support member 5 does not protrude outward in the horizontal direction more than the base member 3. The support member 5 is disposed on the upper surface 102. In the present embodiment, the support member 5 is disposed, for example, at the front end of the plate-like member 45 forming the upper surface 102. The support member 5 is disposed, for example, at the center in the width direction Dw of the plate-like member 45.

[0029] The support member 5 penetrates the plate-like member 45 in the vertical direction Dv and extends to the lower side of the plate-like member 45. A lower plate 51 is provided at the lower end of the support member 5. The lower plate 51 is fixed to the lower surface of the plate-like member 45 by bolts (not shown) or the like. Since the plate-like member 45 is formed of a hard material, the lower plate 51 and the support member 5 are firmly supported by the plate-like member 45.

[0030] FIG. 7 is a perspective view showing the support member 5 and the regulating mechanism 55 provided on the chair body 2. As shown in FIG. 7, a stopper member 56 constituting the regulating mechanism 55 described later is provided at the upper end of the support member 5. The stopper member 56 has an outer diameter larger than that of the upper end of the support member 5. In a plan view, the stopper member 56 is, for example, teardrop-shaped and has a convex portion 56t protruding radially outward in a part of the circumferential direction around the axis of the support member 5.

[0031] As shown in FIGS. 2 and 3, the table top 6 is disposed above the base member 3 with a space therebetween. The table top 6 is provided along a horizontal plane. The table top 6 has a top surface 6f facing upward. The table top 6 is supported by the support member 5. The support member 5 supports one end portion 6a of the table top 6. In the present embodiment, the table top 6 has a rectangular shape in a plan view. The support member 5 supports one end portion 6a on one side in the long side direction of the table top 6.

[0032] As shown in FIG. 3, a table side plate 61 is fixed to the lower surface of the table top plate 6. As shown in FIGS. 3 and 6, a cylindrical portion 61s extending downward is integrally provided on the table side plate 61. The upper end portion of the support member 5 is inserted into the inside of the cylindrical portion 61s from below. A slight clearance is provided in the radial direction between the inner peripheral surface of the cylindrical portion 61s and the outer peripheral surface of the upper end portion of the support member 5. The lower end of the cylindrical portion 61s is supported on a stopper ring 53 (see FIG. 7) provided on the outer peripheral surface of the support member 5. Thereby, the table top plate 6 is rotatably supported around an axis extending in the vertical direction Dv at the upper end portion of the support member 5.

[0033] FIG. 8 is a view showing a state in which the table top plate 6 of the chair body 2 rotates. FIG. 9 is a plan view when the table top plate 6 is in the second state P2. As shown in FIGS. 4, 8, and 9, the table top plate 6 is displaceable between a first state P1 and a second state P2 by rotating around the axis of the support member 5. As shown in FIGS. 4 and 8, in the first state P1, the entire table top plate 6 overlaps the base member 3 in plan view. In the first state P1, at least a part of the table top plate 6 overlaps the upward facing surface 102 in plan view. In the first state P1, the table top plate 6 is located on the side of the seating surface 101. In the first state P1, the table top plate 6 is located vertically above the plate-like member 45 forming the upward facing surface 102. In this state, as shown in FIGS. 2 and 3, a space S capable of storing articles or the like placed on the upward facing surface 102 is formed between the plate-like member 45 and the table top plate 6 located above it.

[0034] As shown in FIG. 4, in the first state P1, the table top 6 having a rectangular shape in plan view is arranged with its long side direction along the front-rear direction Dfr. That is, the table top 6 is long in the front-rear direction Dfr of the base member 3 and short in the width direction Dw of the base member 3 in the first state P1. In the first state P1, the linear table top side portion 6s along the long side direction of the table top 6 is arranged along the side plate 34 forming the side of the base member 3 and parallel to the side plate 34. In the first state P1, the other end portion 6b of the table top 6 on the side opposite to the one end portion 6a supported by the support member 5 is behind the center in the front-rear direction Dfr of the plate-like member 45 (upper surface 102) and in front of the rear end 45r of the plate-like member 45. In the first state P1, the other end portion 6b of the table top 6 overlaps with the backrest 7 in the front-rear direction when viewed in the width direction Dw. In the first state P1, the opposite side portion 6p of the table top 6 located on the side opposite to the table top side portion 6s in the short side direction is on the seating surface 101 side of the boundary between the seating surface 101 and the upper surface 102 and is located on the upper surface 102 side of the backrest 7. That is, the table top 6 straddles the boundary at least at a portion located on the opposite side portion 6p side rather than the central portion (connection portion of the cylindrical portion 61s) in the short side direction. However, in the first state P1, the entire table top 6 may overlap with the upper surface 102 in plan view.

[0035] As shown in FIG. 9, in the second state P2, at least a part of the table top plate 6 is located closer to the seating surface 101 side than in the first state P1. In the second state P2, at least a part of the table top plate 6 overlaps the seating surface 101 in plan view. In the second state P2, the table top plate 6 is arranged to be inclined forward toward the seating surface 101 side in the width direction Dw of the base member 3. In the second state P2, at least a part of the table top plate 6 protrudes forward from the base member 3. In the illustrated example, in the second state P2, the entire opposite side portion 6p protrudes forward from the base member 3, and the top plate side portion 6s does not protrude from the base member 3. In this state, the table top plate 6 is located forward or obliquely forward as viewed from the user seated on the seating surface 101. Note that in the present embodiment, the angle (position) around the axis of the table top plate 6 in the second state P2 is not limited. The angle (position) around the axis of the table top plate 6 is arbitrarily set according to the preference of the user.

[0036] FIG. 10 is a plan view when the table top plate 6 is in the third state P3. As shown in FIGS. 8 and 10, in the present embodiment, the table top plate 6 can also be set to the third state P3. In the third state P3, the table top plate 6 has a larger rotation angle from the first state P1 than in the second state P2. In the illustrated example, in the third state P3, in addition to the entire opposite side portion 6p, a part of the top plate side portion 6s also protrudes forward from the base member 3.

[0037] Here, as shown in FIG. 7, the upper end portion of the support member 5 passes through the table side plate 61 and extends upward. The stopper member 56 is disposed above the table side plate 61. On the upper surface of the table-side plate 61, protrusions 63 and 64 that protrude upward are provided. The protrusions 63 and 64 constitute the restricting mechanism 55. On the lower surface of the table top plate 6, a stopper member 56 and a counterbore 66 that is recessed upward are formed so as to allow the protrusions 63 and 64 to escape. In such a restricting mechanism 55 including the stopper member 56 and the protrusions 63 and 64, when the table-side plate 61 rotates around the axis of the support member 5 integrally with the table top plate 6, either of the protrusions 63 and 64 abuts against the convex portion 56t of the stopper member 56, thereby restricting the rotation range of the table top plate 6. In the present embodiment, the restricting mechanism 55 restricts the rotation range of the table top plate 6 between the first state P1 and the third state P3. Note that the table top plate 6 may be configured to be rotatable only between the first state P1 and the second state P2. In this case, the restricting mechanism 55 restricts the rotation range of the table top plate 6 between the first state P1 and the second state P2.

[0038] As shown in FIGS. 2 and 4, the backrest 7 is provided at the rear end portion of the base member 3. The backrest 7 extends upward from the seating member 40. The backrest 7 has a backrest surface 7f facing forward. The backrest 7 is provided in a part of the width direction Dw of the base portion 31. The backrest 7 is provided in a part of the width direction Dw of the seating member 40. The seating surface 101 is formed to include the front of the backrest 7. Since the user leans on the backrest 7, the user selects his / her position in the width direction Dw with reference to the backrest 7. Thereby, the backrest 7 has a function of guiding the seating position of the user on the seating surface 101 to the region in front of the backrest 7.

[0039] The backrest 7 is arranged closer to the seating surface 101 side in the width direction Dw than the table top plate 6 in the first state P1. Thereby, it is possible to prevent a user sitting at a position in front of the backrest 7 on the seating surface 101 from interfering with the table top plate 6 in the first state P1.

[0040] Also, as shown in FIG. 10, the backrest 7 is arranged to overlap at least a part of the table top plate 6 in the width direction Dw in the second state P2. Thereby, when viewed from a user sitting at a position in front of the backrest 7 on the seating surface 101, the table top plate 6 is arranged forward or obliquely forward, facilitating operations such as working on the top surface 6f. In the illustrated example, in the table top plate 6, the region on the other end portion 6b side with respect to the center in the top plate side portion 6s overlaps the backrest 7 in the width direction Dw.

[0041] As shown in FIG. 7, the wiring connection portion 8 is provided on the upward-facing surface 102. The wiring connection portion 8 is provided on the plate-like member 45. The wiring connection portion 8 is housed in a recess 48 formed in the second support portion 37 of the base portion 31. The wiring connection portion 8 has a connection port 8a that opens upward. The connection port 8a penetrates the plate-like member 45 and is exposed on the upper surface of the plate-like member 45. A user can connect wiring such as electronic devices placed on the table top plate 6 to the connection port 8a. Examples of the wiring connected to the connection port 8a include power supply wiring, communication signal lines, and wiring connected to various connectors.

[0042] As shown in FIG. 4, the wiring connection portion 8 is arranged to overlap the table top plate 6 in the first state P1 in a plan view. Therefore, in the first state P1, the wiring connection portion 8 is covered from above by the table top plate 6. Thereby, when a beverage or the like placed by the user on the top surface 6f spills in the first state P1, it is possible to suppress the liquid from directly falling onto the wiring connection portion 8. Also, as shown in FIG. 9, the wiring connection portion 8 is arranged to be laterally displaced with respect to the table top plate 6 in the second state P2 in a plan view. Therefore, in the second state P2, the wiring connection portion 8 is not covered from above by the table top plate 6 and is exposed upward. Thereby, it is possible to easily insert and remove the wiring connected to electronic devices or the like placed and used on the top surface 6f into and from the wiring connection portion 8.

[0043] In the present embodiment, the wiring connection portion 8 is disposed at an end portion on the side spaced apart from the seating surface 101 in the width direction Dw on the upward-facing surface 102 (plate-like member 45). Thereby, a space on the upward-facing surface 102 can be widely secured and effectively utilized between the wiring connection portion 8 and the seating surface 101. Further, since the wiring is connected to the wiring connection portion 8 at the end portion of the upward-facing surface 102, the wiring is less likely to interfere with a user sitting on the seating surface 101.

[0044] As shown in FIG. 2, the chair body 2 as described above may be configured such that the support structure 30, the wiring connection portion 8, the seating member 40, the skin material 39, and the backrest 7 constitute a chair unit 201, and the plate-like member 45, the support member 5, and the table top plate 6 constitute a table unit 202. When assembling the chair body 2, if the chair unit 201 and the table unit 202 are assembled separately and then the table unit 202 is assembled to the chair unit 201, the assembly work can be performed efficiently.

[0045] As shown in FIG. 1, the panel member 9 includes a back plate portion 91 located behind the base member 3 and side plate portions 92 located on both sides of the base member 3. The panel member 9 is fixed to the base portion 31 of the base member 3 by a mounting bracket or the like (not shown). The back plate portion 91 and the side plate portions 92 rise upward from the base member 3. The panel member 9 is provided so as to surround the space above the upper surface 3t of the base member 3 from the rear and both sides.

[0046] Thus, in the present embodiment, it includes a seating surface 101 facing upward, and an upward-facing surface 102 formed on the side of the seating surface 101 and facing upward, a base member 3 installed on the floor surface F, a table top plate 6 disposed above the base member 3 with a space therebetween and having a top surface 6f facing upward, a support member 5 extending upward from the base member 3 and supporting the table top plate 6, and a wiring connection portion 8 provided on the upward-facing surface 102 and having a connection port 8a opening upward. According to such a configuration, by providing the wiring connection portion 8 having the connection port 8a that opens upward on the upward surface 102 formed on the side of the seating surface 101, the connection port 8a can be easily visually recognized. Therefore, it is possible to insert and remove the wiring into and from the connection port 8a while visually recognizing the connection port 8a. As a result, the visibility of the connection port 8a of the wiring connection portion 8 can be enhanced, and it becomes possible to easily and surely insert and remove the wiring.

[0047] In the present embodiment, the table top plate 6 is supported by the support member 5 so as to be displaceable between a first state P1 in which at least a part of the table top plate 6 overlaps the upward surface 102 in plan view and a second state P2 in which the table top plate 6 is located closer to the seating surface 101 than the first state P1. According to such a configuration, in the first state P1, even if at least a part of the table top plate 6 overlaps the upward surface 102 in plan view and the table top plate 6 is located above the wiring connection portion 8, since the connection port 8a faces upward on the upward surface 102, the visibility of the connection port 8a can be easily ensured. Also, since at least a part of the table top plate 6 overlaps the upward surface 102 in plan view, the table top plate 6 is located on the side of the seating surface 101. Therefore, the accessibility of the user to the seating surface 101 is enhanced. Also, in the first state P1, articles such as the user's belongings can be placed on the top surface 6f of the table top plate 6. At that time, since the table top plate 6 is located on the side of the seating surface 101, it is possible to suppress the articles placed on the top surface 6f from disturbing the user seated on the seating surface 101. Also, in the second state P2, since at least a part of the table top plate 6 is located closer to the seating surface 101 than the first state P1, it overlaps the seating surface 101 in plan view. As a result, at least a part of the table top plate 6 is located in front of the user as seen from the user seated on the seating surface 101. Therefore, in the second state P2, it is easy for the user to perform various operations on the top surface 6f of the table top plate 6.

[0048] In this embodiment, the table top plate 6 is supported by the support member 5 so as to be rotatable about an axis along the vertical direction Dv, and is displaceable between a first state P1 and a second state P2. According to such a configuration, the table top plate 6 can be easily displaced from the first state P1 to the second state P2, and the connection port 8a can be placed in a visible state.

[0049] In this embodiment, in the first state P1, the entire table top plate 6 overlaps the base member 3 in plan view. According to such a configuration, in the first state P1, since the entire table top plate 6 overlaps the base member 3 in plan view, the table top plate 6 does not protrude outward from the base member 3, and interference with the surroundings can be avoided. Even in this state, since the connection port 8a faces upward on the upward-facing surface 102, the visibility of the connection port 8a can be easily ensured.

[0050] In this embodiment, the wiring connection portion 8 is arranged so as to overlap the table top plate 6 in the first state P1 in plan view. According to such a configuration, in the first state P1, the wiring connection portion 8 is covered from above by the table top plate 6. Thereby, when a beverage or the like placed by a user on the top surface 6f of the table top plate 6 spills in the first state P1, it is possible to suppress the liquid from directly falling onto the wiring connection portion 8. Even in this state, since the connection port 8a faces upward on the upward-facing surface 102, the visibility of the connection port 8a can be easily ensured.

[0051] In this embodiment, the wiring connection portion 8 is arranged to be laterally displaced with respect to the table top plate 6 in the second state P2 in plan view. According to such a configuration, the wiring connection portion 8 is not covered from above by the table top plate 6 and is exposed upward. Thereby, the visibility of the connection port 8a is further enhanced.

[0052] In this embodiment, the base member 3 includes a plate-like member 45 having an upward-facing surface 102, and the wiring connection portion 8 is provided on the plate-like member 45. According to such a configuration, by providing the plate-like member 45 having the upward-facing surface 102 on the side of the seating surface 101, the seating surface 101 and the upward-facing surface 102 can be clearly partitioned. As a result, it becomes easier for a user sitting on the seating surface 101 to visually recognize the wiring connection portion 8 provided on the upward-facing surface 102. Also, by providing the wiring connection portion 8 in the plate-like member 45, the wiring connection portion 8 can be firmly supported.

[0053] In the present embodiment, the wiring connection portion 8 is disposed at an end portion on the side spaced apart from the seating surface 101 in the width direction Dw on the upward-facing surface 102. According to such a configuration, a wide space on the upward-facing surface 102 can be secured and effectively utilized between the wiring connection portion 8 and the seating surface 101. Also, since the wiring is connected to the wiring connection portion 8 at the end portion 40s of the upward-facing surface 102, the wiring is less likely to interfere with a user sitting on the seating surface 101.

[0054] (Other Embodiments) As described above, the preferred embodiments of the present invention have been described, but the present invention is not limited to these embodiments. Additions, omissions, substitutions, and other modifications of the configuration are possible without departing from the spirit of the present invention. The present invention is not limited by the above description and is limited only by the appended claims.

[0055] For example, in the above-described embodiment, the wiring connection portion 8 is configured to be disposed at an end portion on the side spaced apart from the seating surface 101 in the width direction Dw on the upward-facing surface 102, but it is not limited to this. The wiring connection portion 8 may be disposed at other appropriate positions within the range of the upward-facing surface 102. For example, if the wiring connection portion 8 is disposed in the vicinity of the support member 5, the wiring of an electronic device or the like placed on the top surface 6f and connected to the connection port 8a is less likely to be pulled even when the table top plate 6 is rotated.

[0056] In the above-described embodiment, the table top plate 6 is configured to be rotatable, but it is not limited thereto. For example, as shown in FIG. 11, the table top plate 6 may be provided on a receiving member 58 provided at the upper end of the support member 5 so as to be slidable in the width direction Dw (a direction orthogonal to the plane of FIG. 11) via a slide guide 59. In such a configuration, the table top plate 6 is configured to be displaceable between a first state P1 and a second state P2 by sliding in the width direction Dw. In this case, even when the wiring connection portion 8 is disposed directly below the table top plate 6, since the connection port 8a of the wiring connection portion 8 covered from above by the table top plate 6 faces upward on the upward-facing surface 102, the visibility of the connection port 8a can be easily ensured.

[0057] In the above-described embodiment, the configuration in which the wiring connection portion 8 overlaps the table top plate 6 in a plan view at least in the first state P1 has been described, but it is not limited to this configuration. The wiring connection portion 8 may be configured not to overlap the table top plate 6 as long as it is open upward on the upward-facing surface 102.

[0058] In the above-described embodiment, the case where the upper surface of the plate-like member 45 is the upward-facing surface 102 has been described, but it is not limited to this configuration. Only the periphery of the wiring connection portion 8 in the base member 3 may be configured as the upward-facing surface 102, and the remaining portions may all be configured as the seating surface 101.

[0059] In the above-described embodiment, the configuration in which the upward-facing surface 102 is provided only on one side in the width direction Dw with respect to the seating surface 101 has been described, but it is not limited to this configuration. The upward-facing surface 102 may be provided on both sides in the width direction Dw with respect to the seating surface 101.

[0060] In the above-described embodiment, the configuration in which the chair 1 includes the backrest 7, the panel member 9, and the plate-like member 45 has been described, but it may be a configuration that does not include at least any one of the backrest 7, the panel member 9, and the plate-like member 45.

[0061] In the above-described embodiments, the configuration in which the table top plate 6 is positioned in front of the base member 3 in the second state P2 and the third state P3 has been described. However, the present invention is not limited to this configuration. In the second state P2 and the third state P3, the entire table top plate 6 may overlap with the base member 3 in a plan view.

[0062] In the above-described embodiments, the seating surface 101 and the upward-facing surface 102 are formed of different materials. However, the present invention is not limited to this. The seating surface 101 and the upward-facing surface 102 may also be formed of the same material.

[0063] In the above-described embodiments, the table top plate 6 has a rectangular shape in a plan view. However, the present invention is not limited to this. The planar shape of the table top plate 6 can be changed as appropriate. Further, in the above embodiment, the support member 5 is arranged at the center in the width direction Dw of the plate-like member 45 at the front end of the plate-like member 45. However, the present invention is not limited to this. The position of the support member 5 can be changed as appropriate. In addition, within a range not departing from the gist of the present invention, it is possible to appropriately replace the components in the above-described embodiments with well-known components, and the above-described modification examples may also be appropriately combined.
