Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a foldable room chair used when sitting in a room.

[0002]

[Prior art]

 When sitting in a sitting room with legs folded for a long time, sitting chairs have long been used to prevent numbness and cramps from occurring in the feet. There are various types of chairs with various shapes and decorations according to preference, but in general there is a seat plate with a soft seat fixed on a horizontal plate, and a seat plate at both ends of which is several tens of cm above the floor. The holding legs are fixed.

[0003]

[Problems to be solved by the invention]

 However, the above-mentioned conventional tatami chair cannot be folded because the legs are fixed to the seat plate. Legs generally have a height of about 20 to 30 cm. However, when the legs are fixed and not used or stored in a storage when not in use, the proportion of the storage space is large because of the height of the legs. Cannot be stored compactly.

[0004] The present invention has been made in consideration of the above-mentioned problem, and it has been proposed that, when a chair is stored, a leg material is displaced so as to substantially overlap within a range of a seat plate so that the chair can be stored in a minimum storage space. Make it an issue.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides leg members at both ends of a seat plate having a flexible and resilient seat so as to be freely foldable with respect to the seat plate by a link rotation support mechanism. The foldable chair is constructed so that it is supported perpendicular to the board, and when not in use, the legs are parallel to the seat and in a plan view, most of the seats are folded within the area of the seat. .

[0006] The above-mentioned tatami chair is used when sitting in a tatami room for a long time in a sitting position or with legs extended and relaxed. In use, the leg is set upright to hold the seat plate, and the seat or leg is extended on the seat plate for use. When not in use, the legs are folded parallel to the seat and stored.The whole is flat and thin, and the legs are mostly within the size of the seat, and they are not standing upright. It is convenient for storing in closet and storage.

Embodiment

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view of a foldable Japanese-style room chair according to an embodiment, and FIG. 2 is a side view thereof and an end view taken along a line BB. The shape shown in the figure shows a state in use. The folding chair is provided with leg members 2 at both ends of a seat plate 1 so as to be foldable with respect to the seat plate 1 via a link rotation support mechanism 3. In the illustrated example, the seat plate 1 forms a seat by entirely covering the core material 1b having flexibility and elasticity with the seat cloth 1a and the core plate 1c placed thereunder, and attaching it. It is attached to the plate 1d.

[0008] The seat cloth 1a is subjected to a process of drawing an elegant picture pattern on its surface and enhancing the sense of quality. The core material 1b may be a flexible and elastic material such as an elastic fiber material or a plastic foam material including cotton, or a rubber material. The core plate 1c is a strong rectangular wooden plate having a thickness of about 1 cm. The wooden board is firmly fixed to the mounting plate 1d with wood screws so that it can sufficiently withstand the weight even when used repeatedly for a long time.

In the example shown in the drawing, the leg material 2 is formed so that the upper edge forms a curved slope that is slightly inclined forward, and the front edge also continues to the curved edge. When the end of the seat plate 1 comes in contact with and is supported near the intermediate height, a grip hole 2a is provided slightly above the seat plate 1, and a horizontal member 2b for stabilizing the leg member 2 is provided at the lower end. Fixed. The outer shapes of the seat plate 1 and the leg members 2 may be variously different from those shown in the drawings.

The link rotation support mechanism 3 includes a link 3a for rotatably connecting the seat plate 1 and the leg member 2 to each other, and a support member 3c fixed to the leg member 2 and supporting an end of the seat plate 1. There. One end of the link 3a is rotatably connected to a fixed seat 3b fixed to the bottom surface of the mounting plate 1d of the seat plate 1 via a shaft 3x, and the other end is connected to a support member 3c of the leg member 2 via the shaft 3x. And are rotatably connected. The support member 3c is fixed to the inside of the leg member 2 so that the upper end is located at an intermediate position of the leg member height, and a concave groove 3s is formed at the upper end.

An engaging member 3t at an end of the seat plate 1 is fitted into the concave groove 3s to prevent the seat plate 1 from being pulled out, and is provided so as to support the seat plate 1 with a contact surface including the concave groove 3s. As shown in FIG. 4, four sets of the link rotation support mechanisms 3 are provided symmetrically with respect to the seat plate 1 and the leg member 2 with respect to an orthogonal line (virtual) passing through the center of the seat plate 1. All weights are shared.

In use, the foldable seating chair configured as described above is set upright with the leg material 2 standing on the seat plate 1 as shown in FIG. 1 and FIG. It is used by stretching. When the leg member 2 is set up vertically, the leg member 2 is set up so that the locking member 3t at the end of the seat plate 1 is fitted into the upper concave groove 3s of the support member 3c. When the left and right legs 2 are assembled as shown in FIGS. 2 and 3, the link 3a of the link rotation support mechanism 3 resists the left and right swings of the leg 2 even if the seated person swings slightly left and right. Since the erect state is maintained, the seat can be stably maintained.

The above-mentioned chair is not required, and when stored in a closet or a storage, the leg material 2 is folded against the seat plate 1 and contracted into a flat shape, so that the leg material 2 can be stored in a compact and flat shape. When folding the leg member 2, first, the leg member 2 is pushed down against the seat plate 1, and the concave groove 3 s of the support member 3 c is engaged with the locking member 3 t of the seat plate 1 as shown in FIG. The legs 2 are rotated about the axes 3x and 3x of the link 3a, and folded in parallel to the seat plate 1 as shown in FIG. The contact is made in the closest state at a distance of thickness δ of 3b.

If the leg material 2 is folded and made into a flat plate as described above, if the leg material 2 and the seat plate 1 are tied with a string so as not to be separated from each other, if the leg material 2 is obstructed to be stored in the closet, The storage is compact and can be done without taking up much space. At the time of use, the leg material 2 is used upright in the reverse procedure.

In the illustrated example, the thicknesses of the fixed seat 3b, the link 3a, and the support member 3c are all the same as δ, so that when folded, the seat plate 1 and the leg member 2 pass through these members. Although they are approached with a distance δ apart, their thicknesses need not all be the same. At each position where each link rotation support mechanism 3 is mounted, the fixed seat 3b is embedded in the core plate 1c of the seat plate 1, while the support member 3c is embedded in the leg member 2, and the link 3a is mounted on the seat plate 1 or leg member. 2 can be folded so that the leg material 2 comes into direct contact with the seat plate 1 regardless of the thickness of these members. Can be thin.

The tatami chair of the above embodiment is generally used in an indoor tatami room, and is considered to be frequently used. For example, the tatami chair is used outdoors for a tea ceremony or a Noh theater. It is needless to say that, as in the case where a floor equivalent to a parquet floor is installed and used there, it is not necessarily limited to an indoor parquet floor and can be used on an outdoor parquet floor.

[0017]

[Effect of the invention]

 As described in detail above, the folding chair of the present invention has leg members provided at both ends of the seat plate so as to be freely foldable by the link rotation support mechanism. Because it is folded parallel to the board and folded in parallel, it contracts into a flat shape, so it can function as a normal tatami chair when in use, and can be folded into a contracted state when not in use by folding the legs. There is the advantage that the legs can be folded out of the way during storage, without impairing the function as a stable tatami chair, and can be stored without taking up much storage space.
