A chair 10 according to an embodiment will be described based on the drawings. A chair 10 is shown in FIGS. 1-7. FIG. 1 shows a perspective view of a chair 10. 2 shows a front view of the chair 10, FIG. 3 shows a back view of the chair 10, FIG. 4 shows a top view of the chair 10, FIG. 5 shows a bottom view of the chair 10, and FIG. A right side view is shown. FIG. 7 is a perspective view of the chair 10 shown in FIG. 1, and the outlines of the tatami mats 12 and 14 (or recesses 16 and 18) are shown in broken lines. Note that the left side view of the chair 10 is symmetrical to the right side view of FIG. 6, so illustration thereof is omitted.

The chair 10 includes tatami mats 12 and 14. The chair 10 includes a seat portion 20, a backrest portion 22, and leg portions 24. The seat portion 20 and the backrest portion 22 include frame portions 26 and 28 having common dimensions (including a common shape).

The frame portion 26 of the seat portion 20 includes four side portions 26a, 26b, 26c, and 26d and one bottom portion 26e, which define a recessed portion (hereinafter referred to as a first recessed portion) 16. A tatami mat (hereinafter referred to as first tatami mat) 12 is fitted into this first recess 16 . Due to this fitting, the first tatami 12 is generally accommodated in the first recess 16 without any play. Note that when the first tatami 12 is fitted into the first recess 16, the surface 12a of the first tatami 12 projects outward from the frame 26. Note that the technology of the present disclosure can also allow a mode in which the surface 12a of the first tatami mat 12 does not substantially protrude outward from the frame portion 26.

The frame portion 28 of the backrest portion 22 includes four side portions 28a, 28b, 28c, and 28d and one bottom portion 28e, which define a recessed portion (hereinafter referred to as a second recessed portion) 18. A tatami (hereinafter referred to as second tatami) 14 is fitted into this second recess 18 . Due to this fitting, the second tatami mat 14 is generally accommodated in the second recess 18 without any play. Note that when the second tatami 14 is fitted into the second recess 18, the surface 14a of the second tatami 14 projects outward from the frame 28. Note that the technique of the present disclosure can also allow a mode in which the surface 14a of the second tatami mat 14 does not substantially protrude outward from the frame portion 28.

The first tatami mat 12 and the second tatami mat 14 are designed to have common dimensions (including a common shape). Therefore, the first tatami mat 12 and the second tatami mat 14 are compatible. The first tatami mat 12 has a tatami floor, a tatami face, and a tatami edge. The surface 12a of the first tatami mat 12 corresponds to a tatami surface made of rush. Similarly, the second tatami mat 14 has a tatami floor, a tatami face, and a tatami edge, and the surface 14a of the second tatami 14 corresponds to the tatami face made of rush. However, the tatami facing of the first tatami mat 12 may be manufactured using a material other than rush, such as Japanese paper or resin, or may be made of a chemical product, that is, an industrial tatami facing or a chemical tatami facing. Similarly, the tatami facing of the second tatami mat 14 may be manufactured using a material other than rush, such as Japanese paper or resin, or may be made of a chemical product, that is, an industrial tatami facing or a chemical tatami facing. Note that a tatami without a tatami edge, that is, a tatami that is made up of a tatami surface up to the edge, can also be used as at least one of the first tatami 12 and the second tatami 14. Note that in this embodiment, the first tatami mat 12 and the second tatami mat 14 are compatible, but at least one of the design, size, and shape of the first tatami mat 12 is changed from that of the second tatami mat 14 or Alternatively, the first tatami mat 12 may be used exclusively for the seat portion 20, and the second tatami mat 14 may be used exclusively for the backrest portion 22. In this case, the first recess 16 may have a shape that corresponds to the first tatami 12, and the second recess 18 may have a shape that corresponds to the second tatami 14.

Although the leg portions 24 are configured to directly support the seat portion 20 and the backrest portion 22 in the chair 10, the leg portions 24 are not limited to this, and may be configured to support at least the seat portion 20. The chair 10 has a plurality of legs 24, more specifically four legs 24a, 24b, 24c, and 24d. However, the legs 24 are not limited to having four legs, and may have one, two, three, five or more legs, and may have various configurations. be. For example, the legs 24 may be foldable. Here, the two front legs 24a and 24b among the four legs are made of substantially round bar members, but the present invention is not limited to this. The legs 24a and 24b are provided to support lower portions of both front ends of the seat portion 20, which is arranged substantially horizontally. The remaining legs 24c and 24d are provided to support a bracket 30 that supports the lower portions of both rear ends of the seat surface 20, and to support the backrest 22 at both ends thereof. The legs 24c and 24d are formed of substantially rectangular plates, but are not limited thereto. Although the bracket 30 is made of wood, it is not limited thereto, and may be made of metal or resin, for example. Similarly, although the frame portion 26 of the seat portion 20 and the frame portion 28 of the backrest portion 22 are each made of wood, the invention is not limited thereto, and for example, at least one of them may be made of metal or resin.

The chair 10 configured as described above further has the following features.

The backrest part 22 is provided so as to be inclined with respect to the seat part 20. Therefore, the surface 12a of the first tatami mat 12 of the seat portion 20 and the surface 14a of the second tatami mat 14 of the backrest portion 22 are designed to have an angle of more than 90°. That is, the angle θ between the surface 12a and the surface 14a shown in FIG. 6 exceeds 90° (θ>90°). The angle θ of the backrest portion 22 with respect to the seat portion 20 is preferably an angle that increases the comfort of the user using the chair 10. Note that this angle θ of the backrest portion 22 with respect to the seat surface portion 20 is preferably an angle at which the second tatami mat 14 is more stably held in the second recess 18.

The first tatami mat 12 is provided on the chair 10 so that the tatami edge 12b of the first tatami mat 12 extends in the width direction A1. The second tatami mat 14 is provided on the chair 10 so that the tatami edge 14b of the second tatami mat 14 extends in the width direction A1. Therefore, when the user sits on the chair 10, the tatami edges 12b, 14b can be prevented from extending to the center of the user's buttocks or along the spine, thereby further enhancing the user's comfort. Note that the present disclosure is not limited thereto, and allows, for example, at least one of the tatami edges 12b and 14b to extend in the depth direction A2 (perpendicular to the width direction A1). The chair 10 is relatively long in the width direction A1, and the tatami mats 12 and 14 each have an elongated shape.

In this way, the chair 10 has features in the tatami mats 12 and 14. Therefore, the chair 10 is shown in FIGS. 8 to 13, with the characteristic parts of the tatami mats 12 and 14 shown in solid lines, and the other parts shown in broken lines. 8 is a front view of the chair 10, FIG. 9 is a rear view of the chair 10, FIG. 10 is a top view of the chair 10, FIG. 11 is a bottom view of the chair 10, and FIG. 12 is a bottom view of the chair 10. FIG. 13 is a right side view, and FIG. 13 is a perspective view of the chair 10. Note that the left side view of the chair 10 is symmetrical to the right side view of FIG. 12, so illustration thereof is omitted.

Although the embodiments and modifications thereof according to the present invention have been described above, the present invention is not limited thereto. Various substitutions and changes are possible without departing from the spirit and scope of the present invention as defined by the utility model claims of the present application.

For example, the chair 10 is a so-called bench-like chair that is long in the width direction A1, but the chair of the present disclosure is not limited to this, and may also have a shape in which the length of the width direction A1 is closer to the depth direction A2. may be included.
