In the conventional sitting chair described in the previous section, the seat is made of a hard material such as wood or metal, so the weight is shifted to reduce or prevent pain such as numbness, but there is little cushioning Therefore, the burden on the pressure surface of the buttocks (5) is large and it cannot be used for a long time sitting on the seat. Use was inconvenient with no sense of stability. Furthermore, it is necessary to equip with equipment during use, and it takes time, so it cannot be used immediately.

In view of these circumstances, portable straight-seat chairs are simple, can be used immediately at the destination, can easily balance even when weight is moved, and reduce or prevent pains such as numbness and assist human body functions Providing a portable sitting chair that can be used on a cushion without damaging the human body and floor, etc. The issue was to help.

A hollow part (2) with a predetermined height (H1), width (L1), depth (L2), and foot (4) that can be inserted between the crotch or both legs (4) when sitting upright is formed with a cushioning material. The orthopedic chair of the present invention reduces the burden on the pressure surface of the buttocks (5) by placing a part of the portable sitting chair on the back of the foot (4) and reduces the weight to reduce or prevent pain such as numbness Even if it moves, it is easy to balance, and even when sitting for a long time, it can sit in a natural posture. In addition, it can be used on a cushion without damaging the human body or floor, thereby solving the problem.

  The cushioning material is protected by covering the entire sitting chair with the cover (6).

By storing the full seat covered with the cover (6) in the bag (3), it is convenient to carry and can be used immediately at the destination.

According to the present invention, since it is made of a cushioning material, it is light, so a part of a portable sitting chair can be placed on the back of the foot (4), and the weight is not concentrated on one point but the pressure surface can be dispersed. And the foot (4) will follow the hollow part (2) lower part, the foot (4) placed by folding a little touches the floor etc. with the shin and instep, and the foot (4) has a large load. Does not enter. Therefore, most of the body weight enters from the sciatic bone and can further support the buttocks (5), so that the user can maintain a constant position in the sitting position, so that balance can be easily taken and numb even if the user moves weight. It is possible to relieve or prevent such pain and assist the human body's function that the person is always moving, so that even when sitting for a long time, the person can sit in a natural posture.

According to the present invention, the portable sitting chair has a softness close to the skin of the human body and thus does not damage the human body or the floor. In addition, even if you accidentally fall from your hand to the floor etc., no sound will be generated, so the atmosphere of the place will not be destroyed. Furthermore, a person with a disability such as a wound or a pain in the foot (4) can be used as a cushion for assisting the handicapped place such as when sitting with the foot (4) collapsed.

According to the present invention, since the bottom surface of the portable seat chair is flat, it can be used on a cushion. Further, the rear of the bottom surface has a convex curved surface like Mt. Fuji due to the formation of the hollow portion (2). This shape has a role like a tail of a kangaroo, that is, the pressure surface can be further dispersed to balance the whole.

According to the present invention, the boundary part from the flat part of the regular seat to the bottom part including the side part is trimmed to a curved surface, and the whole is covered with the cover (6) to protect the cushioning material and to make the human body feel when seated. Good.

According to the present invention, since the sitting chair is contained in the bag body, it is simple and good-looking, and since it has a handle etc., it is convenient to carry. And it can be used immediately at the destination.

  The portable sitting chair of the present invention is a sitting position that can be proud of the world developed in Japan, because it can easily sit up, but it is disliked because it easily causes pain such as numbness of the foot (4). There are a lot of things, but the seat has excellent features such as low center of gravity and low eye line, and it is used in Japanese traditional culture. It will be easy to sit and become one of the bottlenecks in the spread of Japanese traditional culture.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a main body (1) of the present invention according to an embodiment to which the present invention is applied. The cushioning material of the main body (1) of the present invention is entirely covered with a stretchable fabric cover (6) (for example, cotton ribbed) shown in FIGS. 2 to 7, and FIG. A chair is placed in a bag (3) (for example, cotton cloth). FIG. 9 is a diagram of the use of the portable seat chair of the present invention.
