[Industrial applications]

 The present invention relates to a tool for sitting comfortably by slightly lifting the buttocks when sitting by sitting straight, cross-legged, etc.

[0002]

[Prior art]

 Conventionally, most seat chairs used to relieve pain in the ankles and knees caused by sitting and crossing for a long time are of the type that pulls out the legs or the type that folds the legs, and therefore becomes compact. Although it is convenient for carrying around, it is not stable and causes noise when recombining your knees, causing trouble to other people. It had the drawback of leaving marks and scratching the floor between the boards.

In addition, when pulling out or inserting a leg, or when standing up or folding it, it is necessary to operate it with both hands many times, which is very troublesome for a physically handicapped person or an elderly person. And it was inconvenient. In addition, there are often no heating facilities in places where the sitting position continues for a long time, and it has been very difficult to keep warm with conventional seats.

[Problems to be solved by the device]

 The present invention has been made with the object of solving the above-mentioned problems, and it is compact when carried, and even when it is used for a long time, the floor between the boards is kept without leaving a mark on the tatami mat in a Japanese-style room. It does not hurt, has excellent stability, does not generate abnormal noise, and can be folded and assembled with one hand with almost one touch, and if necessary, it can be used with a throwaway warmer to keep warm. It aims to provide a new folding seat chair.

[0005]

[Means for Solving the Problems] As a result of various studies for achieving the above object, a flat bottom plate is used to support the entire weight, and the front face and the top face are integrally rotated with respect to the bottom plate. It was found that it would be a very suitable seat chair if it was assembled, the rear plate was attached to the rear side of the rear of the top surface in a foldable manner, and the lower end of the rear plate was received by the rear part of the bottom plate. Furthermore, in order to ensure that the lower end of the back plate is guided to the position where it should come into contact with it, it is more preferable to provide a raised edge and tapered ribs in front of and behind it, and also, the disposable body warmer on the top surface. We have found that it is easier to keep warm by attaching a cover for attaching the.

That is, according to the present invention, an L-shaped plate formed continuously from the front surface to the top surface is rotatably attached to a front portion of a bottom plate having a flat bottom surface, and a rear rear side of the L-shaped plate is attached. A foldable seat chair characterized in that a rear plate is foldably attached to the rear plate so that the lower end of the rear plate is detachably abutted against the rear part of the bottom plate. A raised edge is provided on the rear end of the rear plate to fix the taper rib with a gap between the lower edge of the rear plate and the rear edge, and to insert the disposable body warmer on the L-shaped plate. The creation of a cover was created.

The rear plate (4) is mounted so as to be rotatable as shown in (a), and the rear plate (4) is located behind the rear part of the L-shaped plate (2) about the pin (5) as a rotation center. It is mounted so that it can be folded as shown.

The L-shaped plate (2) is continuously formed from the front surface to the top surface, and if the reinforcing plates (6) are fixed to the left and right sides of the L-shaped plate (2) as shown in the figure, the strength can be improved. It is also suitable because it can be used for mounting the pins (3) and (5). That is, in this embodiment, the protrusions (7) provided at both front ends of the bottom plate (1) and the left and right reinforcing plates (6) are incorporated by the pins (3), respectively, and the L-shaped plate (2) is the bottom plate. It is designed to be rotatable with respect to (1).

If the back reinforcing plate (8) is fixed to both the left and right sides of the back plate (4), the strength can be improved and the reinforcing plate (6) and the back reinforcing plate (8) can be attached. By utilizing the pin (5), the back plate (4) can be assembled so as to be foldable with respect to the L-shaped plate (2). The lower end of the back plate (4) is detachably abutted on the rear part of the bottom plate (1).

In this case, a raised edge (9) is provided at the rear end of the bottom plate (1) as shown in the figure, and the lower end of the back plate (4) is in contact with the raised edge (9). It is very suitable to fix the taper ribs (10) at a contacting interval. The taper rib (10) has a triangular cross section as shown in the figure, for example, and has a taper portion inclined toward a valley where the lower end of the back plate (4) abuts. Since it can be reliably guided to this valley, the assembly can be easily brought into contact with a predetermined position by simply pressing it from the top, and the assembled state can be stably and safely maintained by the action with the raised edge (9). .
