Description

  The present invention relates to a sitting tool. More particularly, the present invention relates to a sitting tool that activates an autonomous action of a human to improve the posture naturally.

  Since ancient times, it has become a lifestyle in Japan to sit on a tatami mat. And when sitting on a tatami mat, if you sit on the front, you can sit in good posture with your back straight. However, you cannot sit for a long time in the sitting position.

  In addition, if you sit with your legs crossed, your hips and lower back will fall, and your back will naturally round, straining your hips and spine, and fatigue.

  However, in Zen meditation, which requires sitting for a long time in a good posture, a semicircular cushion (sitting) is laid under the hips and the hips and hips are raised. And if this sitting tool is used, the burden on a waist | wrist will be reduced rather than using a general cushion.

  However, since each person's height, weight, and flesh are different, uniform seating does not reduce the burden on the majority of people, it creates a feeling of pressure on the buttocks, and sitting for a long time is painful. It will be a series of patience.

  The present invention has been made in view of the problems of the prior art, and has as its main object to provide a sitting tool that can alleviate the pain in zazen and improve the posture.

The sitting tool of the present invention is a sitting tool composed of a sitting tool body and a cover that covers the sitting tool body, and the sitting tool body has a narrow part where the buttocks ride and a wide part located inside the knee. is a is, and trapezoidal rice cake-like with rounded corners, top plan of zag body is elliptical having a long axis in the width direction, the surface towards the lower bottom from the top plane, said lower base The angle of inclination of the gently inclined surface is such that the inside of the thigh does not come into contact with the surface of the sitting tool when the hip is on the top plane .

In the sitting tool of the present invention, it is more preferable that the surface from the top plane toward the upper base and the surfaces toward both sides are steeply inclined surfaces.

  Moreover, in the sitting tool of this invention, it is preferable that a sitting tool main body consists of an aggregate part and an outer skin part provided so that this aggregate part surface might be covered.

  Furthermore, in the sitting tool of the present invention, it is preferable that the hardness of the sitting tool body is different.

  According to the sitting tool of the present invention, an excellent effect that the back muscles are stretched and the posture is improved by the action of the autonomic nerve can be obtained.

  In addition, according to the preferred embodiment of the present invention, the pelvis can be moved to the left and right because the part other than the part where the buttocks ride is inclined, and by moving the pelvis to the left and right, the lumbar vertebrae and the spine move to feel fatigue. Sit for a long time without any numbness in the legs because the thigh is softened, the healing power works, the body is loosened, and the thighs are not compressed An excellent effect is obtained.

  Hereinafter, although the present invention is explained based on an embodiment, referring to an accompanying drawing, the present invention is not limited only to this embodiment.

  The sitting tool includes a sitting tool body 1 and a cover that covers the sitting tool body 1.

  As the cover, a conventionally used cover such as cloth or vinyl for the skin of the cushion can be suitably used.

  As shown in FIGS. 1 to 6, the shape of the sitting body 1 is a trapezoidal mirror with a narrow spot on the hip, a wide spot on the inner side of the knee, and rounded corners. Hereinafter, the narrow side is referred to as the upper base, and the wide side is referred to as the lower base. Here, the length of the upper base is about 35 cm to 40 cm, and the length of the lower base is about 40 cm to 45 cm.

  As shown by the dotted line in FIG. 1, the portion corresponding to the top plane 1a of the mirror is positioned at the place where the hip rides on the sitting tool, and the shape is an ellipse whose major axis is parallel to the upper base. . The height of the top plane 1a is about 6 cm to 8 cm. The position of the long axis of the ellipse is located approximately 1/3 from the upper base, and the length is about 60% to 70% of the trapezoidal width at that position. The length of the minor axis of the ellipse is about 20 to 30% of the height of the trapezoid.

  The rear side of the top plane 1a, that is, the upper bottom side is a steeply convex curved surface, the front side of the top plane 1a, that is, the lower bottom side is a gently inclined convex curved surface, and both sides are steeply convex curved surfaces. .

  The width of the gently inclined convex curved surface on the front side of the top plane 1a, that is, the length in the front-rear direction is about 30% to 40% of the height of the trapezoid. The angle of the gentle inclination is adjusted so that the inner side of the thigh does not come into contact with the surface of the sitting tool with the buttocks on the top plane 1a. Note that the front side of the top flat surface 1a has a gently inclined convex curved surface and the steeply curved convex curved surface.

  The material of the sitting tool body 1 is, for example, a synthetic resin (for example, urethane foam), and the hardness thereof is three types: hard, medium, and soft. The reason why different hardnesses are prepared is that each person has different physique, weight, and flesh, so that they can cope with it. Moreover, even if it is the same person, it is for taking into consideration that a mood change can be aimed at by changing the hardness grade of a sitting tool. For example, if you sit on a hard seat, you will feel more tense and improve your efficiency. If you sit on a medium-height seat, you can work while thinking, and if you sit on a soft seat, you can relax. I can work in the mood.

  Here, “hard” means that the Shore hardness is in the range of 90-95 degrees, and the amount of settlement when a normal adult (weight 60 kg) rests on the butt is about 27 mm. “Medium” means that the Shore hardness is in the range of 80-85 degrees, and the amount of settlement when a normal adult (body weight 60 kg) puts the buttocks on the seat is about 30 mm. "Soft" means that the Shore hardness is in the range of 70-75 degrees, and the amount of settlement when a normal adult (body weight 60 kg) puts the buttocks on the seat is about 34 mm Say.

  Although the sitting tool body 1 may be an integrated object, as shown in FIG. 7, an aggregate part (core material) 11 that maintains mechanical strength and an outer skin part that covers the surface of the aggregate part 11 are provided. 12 may be configured. In that case, the degree of hardness of the sitting tool body 1 is adjusted by the skin portion 12.

  The material of the aggregate part 11 is hard synthetic resin or wood.

  Therefore, according to the sitting tool of the present embodiment, the following effects can be obtained.

  Effect 1: Since the slope is down except for the part where the hips ride, the back muscles are stretched by the action of the autonomic nerve and the posture is improved.

  Effect 2: Since the part other than the part where the butt rides is a downward slope, the pelvis can be moved from side to side, and by moving the pelvis from side to side, the lumbar vertebrae and spine move, relieving fatigue and healing power, The body is relaxed and a comfortable feeling is obtained.

  Effect 3: Since the thighs are not compressed, the legs are not numb and can sit for a long time. It is suitable for Zazen that requires sitting for a long time.

  As mentioned above, although this invention has been demonstrated based on embodiment, this invention is not limited only to this embodiment, A various change is possible. For example, although described as a sitting tool in the present embodiment, the present invention is not limited to the application of the sitting tool alone, and can be used as a spinal bending and stretching exercise tool by sleeping on the sitting tool under the spine. .

  The present invention can be applied to a sitting tool.

It is a top view of an example of the sitting tool body concerning one embodiment of the present invention. It is the same front view. It is the same side view. It is the IV-IV sectional view taken on the line of FIG. It is the VV sectional view taken on the line. It is the VI-VI sectional view taken on the line. It is sectional drawing of the other example of the sitting tool main body which concerns on one Embodiment of this invention.
