Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair which can be suitably used for meditation and meditation which are carried out to eliminate mental stress and maintain a healthy physical condition.

[0002]

2. Description of the Related Art In today's social life, many people complain of mental stress, and there are many diseases caused by mental stress. Zazen and meditation are known as means for relieving such stress.

Normally, zazen is usually performed with the legs crossed, but since it causes pain such as numbness in the legs, zazen has been developed while sitting on a chair. This is also to spread Zazen to the general public, including foreigners.

In meditation, it is basic to perform abdominal breathing together with Zazen, and a few abdominal breathing is performed quietly before entering a meditation state. The key to abdominal breathing is straightening your back and relaxing your entire body.

Conventionally, no dedicated chair for performing meditation and meditation has been known, and an ordinary comfortable chair with a backrest has to be used.

[0006]

According to the prior art, the conventional chair having a backrest does not contact the backrest when the back is extended because the backrest is inclined rearward. There was a problem that it was difficult to maintain a good posture in which the body was straightened for a long time.

Therefore, in view of the problems of the prior art, the object of the present invention is to incline the seat plate rearward with respect to the horizontal plane and to incline the lumbar plate forward with respect to the vertical plane along the rear legs. Therefore, even if it is a beginner, it is to provide a chair that can easily maintain a good posture with the back stretched for a long time.

[0008]

The structure of the present invention for achieving the above object comprises a front leg, a rear leg, a seat plate and a lumbar support plate, and the seat plate is 6 degrees to 10 degrees with respect to a horizontal plane. The gist of the invention is to incline rearward by a first inclination angle of 10 degrees and to incline the lumbar support plate forward with a second inclination angle of 10 to 15 degrees with respect to the vertical plane along the rear legs.

A footrest can be attached to the front leg.

[0010]

According to the structure of the invention, the seat plate is slanted rearward with respect to the horizontal plane so that the user's buttocks can be slid rearward so that the seat plate is lightly placed between the seat plate and the lumbar support plate. It can be fitted, and at this time, the waist pad can support the user's waist in an appropriate position. In addition, the lumbar pad can be pushed forward with respect to the vertical plane to push the user's lumbar region forward and straighten the back muscles. Therefore, the user can easily adjust the basic posture of abdominal breathing.

Further, if a footrest is attached to the front leg, even a user whose heel does not reach the floor can stabilize the whole body by putting the sole of the foot on the footrest.

Embodiments Embodiments will be described below with reference to the drawings.

The chair 10 includes front legs 11, 11 and a rear leg 1.
2, 12, a seat plate 13, and a waist support plate 14 (FIGS. 1 and 2).

The front legs 11 and 11 are square members each having a downward taper, and are connected by a front plate 16 and a footrest 18. It is assumed that the front plate 16 and the footrest 18 are formed with tenons 16a, 16a, 18a, 18a at both ends (FIG. 3) and are fitted into recesses (not shown) of the front legs 11, 11. In addition, a foot rest 18b is formed on the footrest 18 by notching the upper surface of the central portion (FIG. 1, FIG.
(Fig. 2).

The rear legs 12 and 12 are deformable members that are longer than the front legs 11 and 11. The lower legs have a downward taper, and the upper portions have mounting surfaces 12a and 12a for the lumbar support plate 14. ing. The central portion of the rear legs 12 and 12 has a rear plate 17
Are connected through the upper mounting surfaces 12a, 12a,
The waist support plate 14 is fixed.

The rear legs 11 and 11 are frame-shaped connected to the front plate 16 connecting the front legs 11 and 11 via the lateral plates 15 and 15. The front end of each lateral plate 15 is connected to the rear surface of the front plate 16 via the tenon 15a (FIG. 3), and the rear end is connected to the front end surface of the rear leg 11 via the tenon 15b (FIG. 1). ). The upper surfaces of the horizontal plates 15 and 15 are inclined rearward with respect to the horizontal plane H at the first inclination angle θ1. Further, a triangular reinforcing plate 19 is mounted on each frame-shaped top formed by the front plate 16, the lateral plates 15, 15, and the rear plate 17 (FIG. 2).

The seat plate 13 is formed by attaching a cushion 13a to the upper surface of a flat and substantially square plate material (FIGS. 1 and 2), and the upper surfaces of the front legs 11, 11, the front plate 16, and the horizontal plates 15, 15. It is fixed on the plane formed by. Therefore, the seat plate 13
Follows the horizontal plates 15 and 15 and is inclined rearward with respect to the horizontal plane H at the first inclination angle θ1.

The waist support plate 14 is formed by attaching a cushion 14a to the front surface of a substantially rectangular plate material which is curved in the lateral direction (FIGS. 1 and 4). As for the thickness of the waist support plate 14, the upper part is thicker and the lower part is thinner so that the user's waist is in close contact with the waist support plate 14. Further, the waist support plate 14 has its rear surface fixed to the mounting surfaces 12a, 12a of the rear legs 12, 12 in close contact with each other. At this time, the front surface of the waist contact plate 14 is inclined forward with respect to the vertical plane V along the rear legs 12 and 12 by the second inclination angle θ2.

The chair 10 thus assembled can be stably placed on the floor by the front legs 11, 11 and the rear legs 12, 12.

The chair 10 can easily and straightly extend the user's back muscles. That is, since the seat plate 13 is tilted backward by the first tilt angle θ1 with respect to the horizontal plane H, the user's buttocks slide backward and fit between the seat plate 13 and the waist support plate 14. It will be in a state (Fig. 1). on the other hand,
Since the waist support plate 14 is inclined forward by the second inclination angle θ2 with respect to the vertical plane V, the waist of the user is supported by the waist support plate 14 by appropriately setting the second inclination angle θ2. Therefore, the user's spine can be straightened.

Here, the first inclination angle θ1 of the seat plate 13 is 6
A range of .ltoreq..theta.1 .ltoreq.10 (degrees) is suitable, and particularly preferably 8 .ltoreq..theta.1 .ltoreq.9 (degrees). For θ1 <6 (degrees),
The buttocks do not fit well, and when θ1> 10 (degrees), they are too tight and cramped. In addition, the second tilt angle θ of the waist support plate 14
2 is preferably in the range of 10≤θ2≤15 (degrees), and particularly preferably 13.5≤θ2≤14.5 (degrees). θ2
At <10 (degrees), the user's body tends to warp, and θ2
When> 15 (degrees), the user leans forward and the buttocks do not fit well.

Further, the height d3 of the lumbar support plate 14 should also be set appropriately. The height d1 of the front legs 11, 11 is about 360 mm so that the user's back muscles are straightened.
When the distance d2 between the rear legs 12, 12 and the rear legs 12, 11 is set to about 410 mm, the height d3 of the waist support plate 14 is 630≤d3.
It is preferable that ≦ 650 (mm).

The footrests 18 attached to the front legs 11 and 11 are
Users with long legs may not use this,
A user whose legs are short and whose heel does not reach the floor can further stabilize the entire body and relax by using the footrest 18.

In the above description, the footrest 18 can be omitted. Further, each constituent member of the chair 10 is not limited to a plate material and may be a pipe material as long as the first tilt angle θ1 and the second tilt angle θ2 can be appropriately set. Any material such as a steel material and a synthetic resin material can be used. The seat plate 1
It is also possible to continuously and integrally mold 3 and the waist support plate 14 with a synthetic resin material.

[0025]

As described above, according to the present invention, the seat plate is inclined rearward with respect to the horizontal plane, and the lumbar support plate is inclined forward with respect to the vertical plane along the rear leg. Since the person's buttocks fit lightly between the seat plate and the lumbar plate, the back muscles can be easily straightened,
Even a beginner can maintain the basic posture of abdominal breathing for a long time, and has an excellent effect that it is easy to unify the mind.
