[0011] The embodiment of the chair will be described below with reference to Figures 1 to 12. The chair of this invention has partitions behind and to the side of the user, allowing the user to sit in a relaxed state in an atmosphere as if they were in a private room, and in that state they can drink beverages, read books, or browse websites on their smartphones. Here, the height direction of the chair is defined as H, the width direction as W, and the thickness direction as T. Furthermore, the upward direction of the height direction H is defined as U, and the downward direction as D. In addition, the forward direction of the thickness direction T is defined as F, and the backward direction as R.

[0012] The chair 11 is configured as a so-called sofa, allowing the user to sit deeply in a relaxed state. As shown in FIGS. 1 to 6 and FIG. 9, the chair 11 includes a lower frame 12 provided at the central portion in the width direction W, a pair of side frames 13 that support the lower frame 12 from the outside in the width direction W, a seat portion 14 supported by the lower frame 12, a support portion 17 that can be attached so as to stand upright with respect to either the first plate portion 15 or the second plate portion 16 of the lower frame 12 described later, a table portion 21 that is attached to the support portion 17 so as to be rotatable in the lateral direction, a first partition 22 that is supported by the pair of side frames 13 and is provided so as to surround the seat portion 14, a second partition 23 attached to the lower frame 12, and a holder component 25 that holds small items with respect to the beam member 24 of the side frame 13.

[0013] As shown in FIG. 6, the lower frame 12 has a lower frame main body 26, a first plate portion 15 provided at the left end in the width direction W when viewed from the front direction, and a second plate portion 16 provided at the right end opposite to the left end in the width direction W when viewed from the front direction. The lower frame main body 26 is formed by welding or the like a hollow metal bar into a square frame. The lower frame main body 26 includes a pair of horizontal frames 27 formed to extend in the width direction W, and a plurality of vertical frames 31 formed to extend in the thickness direction T so as to cross the pair of horizontal frames 27. The distance dimension between the pair of horizontal frames 27 in the thickness direction T has a dimension approximately the same as the dimension of the seat portion 14 in the thickness direction T described later. The plurality of vertical frames 31 are composed of a total of five, one at the central portion in the width direction W and two at each of the left and right ends.

[0014] As shown in FIG. 6, the first plate portion 15 is formed in a substantially circular plate shape. The first plate portion 15 is formed in the vicinity of one of the pair of horizontal frames 27, i.e., the front horizontal frame 27A. Also, the first plate portion 15 is formed on a plurality of vertical frames 31 formed at the left end when viewed from the front. The first plate portion 15 has a plurality of first screw holes 32 (for example, four) for fixing a column portion 17 described later with screws in the vicinity of the outer edge portion of the first plate portion 15.

[0015] The second plate portion 16 is formed in the vicinity of one of the pair of horizontal frames 27, i.e., the front horizontal frame 27A. Also, the second plate portion 16 is formed on a plurality of vertical frames 31 formed at the right end when viewed from the front. The second plate portion 16 is formed in a substantially circular plate shape having the same size as the first plate portion 15. The second plate portion 16 has a plurality of second screw holes 33 (for example, four) for fixing a column portion 17 described later with screws in the vicinity of the outer edge portion of the second plate portion 16. The first plate portion 15 and the second plate portion 16 are connected to the lower frame body 26 by welding or the like.

[0016] As shown in FIG. 6, each of the pair of side frames 13 includes a front leg portion 34 provided at the front side, a rear leg portion 35 provided at the rear side, a connecting portion 36 that connects the upper end portion of the front leg portion 34 and the upper end portion of the rear leg portion 35, a beam member 24 provided below the connecting portion 36 and connecting the front leg portion 34 and the rear leg portion 35, a first support portion 37 provided below the beam member 24 and protruding from the front leg portion 34 toward the center in the width direction W, a second support portion 41 provided below the beam member 24 and protruding from the rear leg portion 35 toward the center in the width direction W, and a third support portion 42 that connects the first support portion 37 and the second support portion 41. The side frame 13 is integrally formed by welding each portion.

[0017] As shown in Figure 6, both the front leg portion 34 and the rear leg portion 35 are formed from hollow rod material. The dimensions D1 between the lower ends of the front leg portion 34 and the rear leg portion 35 are formed to be greater than the dimensions D2 between the upper ends of the upper ends of the legs in the thickness direction T (D1 > D2). In other words, they are formed in a roughly "V" shape when viewed from the side.

[0018] As shown in Figure 6, the beam member 24 is formed approximately midway between the connecting portion 36 and the first support portion 37 and the second support portion 41 in the height direction H. The beam member 24 is formed in a position corresponding to the gap 43 between the first partition 22 and the second partition 23, which will be described later, in the height direction H. The beam member 24 has a plurality of third screw holes 44 on its inside in the width direction W for attaching the holder component 25, which will be described later. The first support portion 37 and the second support portion 41 have a diameter that is slightly smaller than the diameter of the horizontal frame 27 of the lower frame 12. Therefore, the first support portion 37 and the second support portion 41 can be fitted inside the pair of horizontal frames 27. The third support portion 42 is formed to span the centers of the first support portion 37 and the second support portion 41 in the width direction W.

[0019] As shown in Figure 6, the dimension of the connecting portion 36 in the thickness direction T is T1, the dimension of the beam member 24 in the thickness direction T is T2, and the dimension of the third support portion 42 in the thickness direction T is T3. In this case, the dimensional relationship of each of the above is T1 <T2<T3である。

[0020] As shown in Figure 8, the seat portion 14 has a seat body 45 and a through hole 46 that penetrates the seat body 45 in the height direction H. The seat body 45 is formed in a substantially rectangular shape when viewed from above U. The seat body 45 has cushioning material bonded to the surface of a substantially rectangular wooden frame. The top surface 47 and bottom surface 51 of the cushioning material of the seat body 45 are hollowed out in a substantially circular shape around the through hole 46. The through hole 46 is formed on the front side of the seat portion 14 when viewed from the front direction F and on the left end in the width direction W. The through hole 46 is formed with a diameter slightly larger than the first support portion 52 of the support portion 17, which will be described later. Note that the through hole 46 is not essential, and the dimensions of the seat portion in the width direction W may be made smaller than the seat portion 14 of this embodiment, and the smaller seat portion may be placed side by side with respect to the support portion 17.

[0021] As shown in Figure 8, the support column 17 has a first support column 52 that can be attached to the lower frame 12 and a second support column 53 to which the desk portion 21 (described later) can be attached. The support column 17 can house a power cable (not shown) inside. The first support column 52 has a fixing portion 54 that is fixed to the first plate portion 15 or the second plate portion 16 and a first cylindrical portion 55 that is formed in a cylindrical shape.

[0022] As shown in Figure 8, the fixing portion 54 is formed in a substantially disc shape. The fixing portion 54 has a plurality of fourth screw holes (not shown) near its outer edge and a plurality of first support portion fixing screws 56 that pass through each of the plurality of fourth screw holes. The plurality of fourth screw holes are formed in positions that overlap with the plurality of first screw holes 32 and the plurality of second screw holes 33 described above (for example, four). The plurality of first support portion fixing screws 56 can fix the fixing portion 54 to the first screw holes 32 or the second screw holes 33 by screwing the screws together. The fixing portion 54 of the first support portion 52 can be placed on top of the first plate portion 15 or the second plate portion 16 of the lower frame 12, and the support portion 17 can be fixed to the first plate portion 15 or the second plate portion 16 by screwing screws (not shown) into the first screw holes 32 or the second screw holes 33 and the fourth screw holes 56.

[0023] In this embodiment, as an example, the support column 17 is fixed to the first plate portion 15 with screws. The first cylindrical portion 55 is formed in an elongated cylindrical shape in the height direction H. The first cylindrical portion 55 is formed to stand upright from the fixing portion 54 in the upward direction U. The first cylindrical portion 55 is connected to the approximate center of the fixing portion 54 by welding or the like.

[0024] As shown in Figures 5 and 8, the second support column 53 has a desk mounting portion 57 which is attached to the desk portion 21 described later, a second cylindrical portion 61 which is formed in a cylindrical shape, an outlet 62 which is formed on the outer surface of the second cylindrical portion 61 and connected to a power cable, and a locking portion 63 which is formed at the lower end of the second cylindrical portion 61.

[0025] As shown in Figures 5 and 8, the desk mounting portion 57 is formed in the shape of a roughly square plate. The desk mounting portion 57 rotatably supports the desk portion 21. The second cylindrical portion 61 is formed to stand upright from the center of the desk mounting portion 57 toward a downward direction D. The second cylindrical portion 61 is connected to the desk mounting portion 57 by welding or the like. The inner diameter of the second cylindrical portion 61 is formed to be slightly larger than the inner diameter of the first cylindrical portion 55. Therefore, the first cylindrical portion 55 can be fitted inside the second cylindrical portion 61. The first support portion 52 and the second support portion 53 are fixed by screws or the like after being fitted in place.

[0026] As shown in Figure 5, the outlet 62 is formed on the side surface of the second cylindrical portion 61. The outlet 62 is positioned opposite the back portion 64 of the second partition 23, which will be described later. As shown in Figure 8, the locking portion 63 is formed in a flat, approximately ring shape that extends approximately horizontally from the second cylindrical portion 61. Therefore, when the first support portion 52 is fitted onto the second support portion 53, the locking portion 63 of the second support portion 53 is locked to the base body 45. Thus, it is possible to prevent the second support portion 53 from penetrating the through hole portion 46.

[0027] As shown in Figures 5 and 8, the desk section 21 has a desk body 65 formed in a substantially trapezoidal shape, and a rotating shaft 66 formed below the desk body 65 and capable of rotating at that position. The rotating shaft 66 is rotatably attached to the desk mounting portion 57 of the second support column 53. The rotating shaft 66 is formed in a substantially disc shape. The desk body 65 is formed in a flat plate shape from a material such as wood. As shown in Figure 5, the desk body 65 is formed such that, when viewed from above U, the dimensions of the desk section 21 in the short-side direction decrease as it moves away from the support column 17. The desk body 65 is fixed to the rotating shaft 66, which will be described later, in the vicinity of the support column 17. Therefore, as shown in Figure 7, the desk body 65 and the rotating shaft 66 are rotatable laterally around the support column 17. Here, the later direction may be parallel to the horizontal plane or substantially parallel to the horizontal plane. Here, the direction approximately parallel to the horizontal plane may be a direction inclined by a few degrees downward D from the horizontal direction. Alternatively, the direction approximately parallel to the horizontal plane may be a direction inclined by a few degrees upward U from the horizontal direction.

[0028] As shown in Figure 1, the first partition 22 is formed in a roughly "U" shape with an opening facing forward when viewed from above U. The first partition 22 is integrally formed from a felt material or the like. As shown in Figures 3, 5, and 6, the first partition 22 has an inner wall portion 67 located inside the chair 11, an outer wall portion 71 located outside the chair 11, and contact portions 72 that abut against the respective connecting portions 36 of the pair of side frames 13.

[0029] The first partition 22 is mounted so as to cover the pair of side frames 13 from above in the upward U shape. The cross-sectional shape of the first partition portion 22 when cut along the height direction H is formed in a substantially inverted "U" shape. As shown in FIG. 5, the dimension H1 of the inner wall portion 67 located inside the chair 11 in the height direction H of the first partition 22 is formed to be smaller than the dimension H2 of the outer wall portion 71 located outside the chair 11 in the height direction H (H1 < H2). As shown in FIGS. 1, 2, 5, and 6, the first partition 22 is fixed to the front legs 34 and the rear legs 35 of the pair of side frames 13 from the inside of the chair 11 by screws.

[0030] As shown in FIG. 1, the second partition 23 is provided so as to surround the seat portion 14. As shown in FIG. 6, the second partition 23 includes a bottom portion 73 formed so as to contact the bottom surface 51 of the seat portion 14, a back portion 64 located on the back surface of the seat portion 14, and a pair of side wall portions 74 formed so as to extend forward in the F direction from both ends in the width direction W of the back portion 64. The second partition 23 is integrally formed of a felt member or the like. The second partition 23 is provided below the first partition 22.

[0031] As shown in Figure 5, the bottom portion 73 is formed to be sandwiched between the lower frame 12 and the seat portion 14. As shown in Figure 6, the bottom portion 73 has a pair of insertion holes 75 for passing the support portion 17 through, at positions corresponding to the first plate portion 15 and the second plate portion 16 of the lower frame 12. As shown in Figures 1 to 3 and Figure 5, the pair of side wall portions 74 are formed on the inside of the pair of side frames 13 with respect to the width direction W. The pair of side wall portions 74 and the back portion 64 have a top surface 76 at a position lower than the position of the beam member 24 of the side frame 13 with respect to the height direction H. That is, the second partition 23 is provided with a gap 43 with respect to the height direction H from the inner wall portion 67 of the first partition 22. Therefore, the beam member 24 of the side frame 13 can be exposed between the first partition 22 and the second partition 23. As shown in Figures 1, 2, 5, and 6, the second partition 23 is fixed to the front legs 34 and rear legs 35 of the pair of side frames 13 from the inside of the chair 11 by screws.

[0032] As shown in Figure 9, the chair 11 allows holder components 25 to be attached to each beam member 24 of the pair of side frames 13 from the inside of the chair 11. The holder component 25 may, for example, be a bottle holder capable of supporting a cylindrical small medium such as a PET bottle as shown in Figure 10, or, as another example, a tablet stand capable of supporting a plate-shaped small medium such as a tablet terminal as shown in Figure 11, or a holder that supports any other small medium. The holder component 25 has a storage section 77 capable of supporting a small medium and a storage section mounting section 81 that is attached to each beam member 24 of the pair of side frames 13 mentioned above. The storage section 77 may have components that can be appropriately replaced depending on the small medium to be stored. The storage section mounting section 81 has a fifth screw hole 82 for fixing the holder component 25 to the beam member 24 with a screw or the like.

[0033] The assembly method of the chair 11 of this embodiment will be described with reference to Figures 6 and 8. First, as the first step, the first support portion 37 and the second support portion 41 of the pair of side frames 13 are fitted onto the pair of horizontal frames 27 so that the first plate portion 15 and the second plate portion 16 of the lower frame 12 are positioned towards the front. Then, the lower frame 12 and the pair of side frames 13 are fixed together with screws (not shown).

[0034] In the second step, the first support column 52 of the support column 17 is fixed to the first plate 15 with screws (if the desk 21 is to be attached to the right side of the chair 11 when viewed from the front, the first support column 52 of the support column 17 is attached to the second plate 16).

[0035] In the third step, the insertion hole 75 of the second partition 23 is passed through the first support column 52 from the upper direction U, and the second partition 23 is attached to the lower frame 12. At this time, the second partition 23 and the pair of side frames 13 are fixed with screws from the inside of the chair 11.

[0036] In the fourth step, the seat portion 14 is attached to the bottom portion 73 of the second partition 23 by passing the through-hole 46 of the seat portion 14 through the first support portion 52.

[0037] In the fifth step, the second support column 53 is fitted onto the first support column 52 from above (U). Then, the first support column 52 and the second support column 53 are fixed together with screws (not shown). Furthermore, the desk section 21 is fixed to the desk section mounting section 57 of the second support column 53.

[0038] In the sixth step, the first partition 22 is fitted onto the pair of side frames 13 from above (U). Then, the first partition 22 and the pair of side frames 13 are secured to each other with screws from the inside of the chair 11.

[0039] Finally, as the seventh step, the holder component 25 is fixed to each beam member 24 of the pair of side frames 13 from the inside of the chair 11 with screws. This completes the assembly of the chair 11 in this embodiment.

[0040] Next, the operation of the chair 11 of the present embodiment will be described. The first support portion 37 and the second support portion 41 have a diameter that is slightly smaller than the diameter of the horizontal frame 27 of the lower frame 12. Therefore, the first support portion 37 and the second support portion 41 can be fitted inside the pair of horizontal frames 27. The inner diameter dimension of the second cylindrical portion 61 is formed to be slightly larger compared to the inner diameter dimension of the first cylindrical portion 55. Therefore, the first cylindrical portion 55 can be fitted inside the second cylindrical portion 61. The locking portion 63 is formed in a substantially ring shape that is flat and extends in the horizontal direction from the second cylindrical portion 61. Therefore, when the first support column portion 52 is fitted into the second support column portion 53, the locking portion 63 of the second support column portion 53 is locked to the seat body 45. Accordingly, it is possible to prevent the second support column portion 53 from penetrating through the through hole portion 46 as much as possible. The rotating shaft 66 is rotatably attached to the desk attachment portion 57 of the second support column portion 53. Further, the desk body 65 is fixed to the rotating shaft 66 in the vicinity of the support column portion 17. Therefore, the user can smoothly sit on or get off the chair 11 by rotating the desk portion 21 to an arbitrary position. The dimension H1 in the height direction H of the inner wall portion 67 located inside the chair 11 of the first partition 22 is formed to be smaller compared to the dimension H2 in the height direction H of the outer wall portion 71 located outside the chair 11 (H1 < H2). Further, the second partition 23 is provided with a gap 43 in the height direction H with respect to the inner wall portion 67 of the first partition 22. Therefore, the beam member 24 of the side frame 13 can be exposed between the first partition 22 and the second partition 23.

[0041] Next, a modified version of the chair 11A of this embodiment will be described. As shown in Figure 12, in the modified chair 11A, the support column 17 is fixed to the second plate portion 16. Furthermore, in the modified chair 11A, the through hole 46 in the seat portion 14 for passing the support column 17 is formed at the front side of the seat portion 14 when viewed from the front direction F and at the right end in the width direction W. Therefore, the modified chair 11A can be assembled so that the desk portion 21 is located to the right of the chair 11 when viewed from the front. The method of fixing the support column 17 to the second plate portion 16 is the same as the method of fixing the support column 17 to the first plate portion 15 in the above embodiment. The effects and advantages of this modified chair 11A are substantially the same as those of the above embodiment.

[0042] According to this embodiment and its modifications, the following can be said: The chair 11 comprises a lower frame 12 having a first plate portion 15 provided at one end in the width direction W and a second plate portion 16 provided at the other end opposite to the one end in the width direction W; a pair of side frames 13 supporting the lower frame 12 from the outside in the width direction W; a seat portion 14 supported by the lower frame 12; a support column 17 that can be attached to stand upright on either the first plate portion 15 or the second plate portion 16; a desk portion 21 that is rotatably attached laterally to the support column 17; and a first partition 22 that is supported by the pair of side frames 13 and is provided to surround the seat portion 14.

[0043] With this configuration, since the first plate portion 15 and the second plate portion 16 are formed at both ends of the lower frame 12 with respect to the width direction W, the desk portion 21 can be fixed to any position on either the left or right side of the chair. Therefore, users can be provided with a chair 11 that can be fitted with the desk portion 21 on either the left or right side of the chair, depending on the application.

[0044] In this case, the chair 11 includes a second partition 23 attached to the lower frame 12, which is located below the first partition 22, with a gap 43 in the height direction H relative to the first partition 22, and is provided so as to surround the seat 14.

[0045] In this configuration, the partition section is composed of two parts: a first partition 22 and a second partition 23. Therefore, compared to partitions that are not divided into parts, it can be packaged in less space during transport. Consequently, transportation costs can be reduced.

[0046] In this case, the pair of side frames 13 have beam members 24 at positions corresponding to the gap 43, and a holder component 25 for holding small objects can be attached to the beam members 24.

[0047] This configuration allows for the attachment of holder components 25 to the beam member 24, thereby improving user efficiency. For example, by attaching drink holders or tablet stands to the beam member 24, a space can be provided for users that is both relaxing and offers improved work efficiency.

[0048] In this case, the support column 17 is capable of housing a power cable inside, and has an outlet 62 connected to the power cable in a position facing the back 64 of the second partition 23.

[0049] With this configuration, since the power outlet 62 is formed in the support column 17, a large space can be secured for the seat 14 of the chair 11. Therefore, it is possible to prevent the power outlet 62 from getting in the way when the user sits down or gets up, or when they are working. Thus, the user's work efficiency and ease of sitting down and getting up can be ensured.

[0050] The embodiments described above can be implemented with various further substitutions and modifications. Naturally, the different embodiments and modifications described above can also be combined as appropriate to constitute a single invention. [Explanation of symbols]
