【０００１】
【発明の属する技術分野】
本発明は、椅子に関する。
【０００２】
【従来の技術】
従来の椅子の座面は、フラット、若しくは体圧を分散するような形態であった。
【０００３】
【発明が解決しようとする課題】
本発明は、人体座骨部の形態を考え人が座った時に脊柱が鉛直線状にり、且つ、骨盤に圧力が加わる事により、術者にとって患者を矯正しやすくする。
【０００４】
【課題が解決しようとする手段】
前記目的を達成する為に、座面座骨接触部材１を椅子前面側から見て角度を付けて固定し、且つ、椅子側面側Ｂ，Ｃから見て角度を付けたもので、座骨接触部材１は三角柱にする事により、より安価に、且つ、丈夫になる。
【０００５】
又、踏み台３、そして左右の踏み台の間１１を有する事により、術者の手法により患者との密着度、適正な位置を確保する。
【０００６】
【発明の実施の形態】
本発明の椅子を実施例に基づいて説明する。
【０００７】
【実施例】
（第１実施例）
図１は本発明の椅子５を、上部から見た図、図２は椅子５に設置してある座骨接触部材１を上部から見た図、図３は椅子５を側面側Ｂから見た図、図４は椅子５に設置した座骨接触部材１を座骨接触部材１から見て側面から見た図、図５は椅子５を後方側Ｄから見た図、図６は椅子５を前方側Ａから見た図である。
【０００８】
フラットな座面１２に座骨接触部材１は椅子５に中央に位置する対象軸２に対して左右一対づつ対象に位置して固定しており（中央にある対象軸２に対して左右が線対象に位置している）、座骨接触部材１は三角柱のかたちをしており、立方体、若しくは、正立方体の対角線上で二つに割ったかたちをしていて、座骨接触部材１の角度的位置は、向かい合う左右２つの座骨接触部材１の互いに前方側Ａに向かい（左右の平面であって斜面である座面９は対象軸２方向に向かい合っている）、且つ、平面で斜面である座面９の底辺１３の延長線の交わる角度６は、４０度から１１０度（理想角度は６０度）、これは図１と図２の座面９の底辺１３の延長線の角度６である。そして、図４の座骨接触部材１を側面から見た角度７は２０度から７０度（理想角度は、３５度から４５度）の角度を有する事により（ようするに左右の斜面である座面９は椅子５の前面にたいして前内上方を向いている）、人が座った時、人体座骨部が座骨接触部材１に接触しこの角度と重力により、仙腸関節に圧力が加わり、且つ、姿勢はよくなり、人体を矯正する際に術者は軽い力で矯正が出来る。
【０００９】
又、左右の座骨接触部材１と座骨接触部材１の間の最短距離８は０．１センチメートル以上、１０センチメートル以下とし、そして、後方側Ｄから見て左右の座骨接触部材１の平面であって斜面である座面９はお互い対象軸２に向いており（お互い内側に向き合っており）、且つ斜面である座面９の底辺１３は前方側Ａに向かって斜め外側に向かっていて、座面９は角度７を有する為子供から大人まで色々な左右の座骨の幅の大きさ（殿部の大きさ）をカバー出来る。
【００１０】
そして、後方側Ｄから見て左右の座骨接触部材１の平面であって斜面である座面９はお互い対象軸２に向いており（お互い内側に向き合っており）、斜面である座面９の底辺１３は前方側Ａに向かって斜め外側に向かっている為、患者が斜面である座面９に座骨部を乗せて座った時に患者の骨盤はしまり背筋は伸び、後方側Ｄから見た左右の辺１４お互いに接していない。
【００１２】
尚、斜面である座面９の底辺１３の大きさは５センチメートル以上でないと安定した骨盤を確保出来ず、辺１４の大きさも７５ミリメートル以上でなければ安定した骨盤を確保できない。
【００１３】
尚、三角柱である座骨接触部材１のかたちは、斜面である座面９の方向的角度６、又、斜面である座面９の側面のから見た角度７は、三角柱で無くても前記に記す斜面である座面９の角度６、又斜面である座面９の側面のから見た角度７、その他の斜面である座面９の位置的なものも確保出来ればどの様なかたちでも良い。
【００１４】
尚、斜面である座面９は図説しないが斜面である座面９を覆うカバーがあり、平面で斜面である座面９とそのカバーの間にはクッション材が存在するように作り、この事により人体座骨部の違和感を取り除け、又平面で斜面である座面９は殿部の曲線あった曲線（凹がた）にっする事により、より違和感を取り除ける。
【００１５】
又、椅子の脚１０は図説していないが高さを調節する駆動装置を有しており、そして左右の座骨接触部材１は斜面である座面９の角度、お互いの距離、お互いの図２に示す角度６は各々駆動する駆動装置を有している為、色々な患者の背骨の高さ、かたち等に適応できる。
【００１６】
又、患者の頸椎以上を矯正する場合術者はより高い位置から矯正した方が力の入力がしやすく、且つ、色々な患者に対応させる為、踏み台３を後方部に装着し（踏み台３は高さを調節できる駆動装置を内蔵している。）、且つ患者との密着度を計り易くする為に、左右の踏み台３の隙間１１を設ける。
【００１７】
そして、斜面である座面９は斜面である為、前方に滑り安くそれを防ぐ為斜面である座面９の表面に０．３ミリメートル以上の凹凸を付けるか、樹脂、ゴム等の滑り止めを有すか、０．３ミリメートル以上の凹凸を有する樹脂、ゴム等の滑り止めを有し、座る人の臀部の滑りを防ぐ。
【００１８】
又、斜面である座面９を底辺１３を支点として可動させる為、斜面である座面９の底辺１３は、人が座った時の大腿部後面が当たる面と留める際、蝶番、若しくは、ゴム、樹脂等の弾性体を取り付けて支店部材として用いて、斜面である座面９の底辺１３を可動させ、図説していないが座面９の角度は駆動装置が内蔵されており角度を自由に変えることが出来る。
【００１９】
又、斜面である座面９を底辺１３の対称辺１５も支点として可動させる時は、底辺１３を固定しないで、斜面である座面９の底辺１３の対称辺１５は、人が座った時の大腿部後面が当たる面と留める際、蝶番、若しくは、ゴム、樹脂等の弾性体を取り付けて支店部材として用いて、底辺１３の対称辺１５も可動させ、図説していないが座面９の角度は駆動装置が内蔵されており角度を自由に変えることが出来る。
【００２０】
【発明の効果】
前記により患者は本発明の椅子に座ることにより脊椎は伸び、術者は矯正をしやすく成った。

DETAILED DESCRIPTION OF THE INVENTION
The chair of this invention is demonstrated based on an Example.
[0007]
【Example】
(First embodiment)
1 is a view of the chair 5 of the present invention as viewed from above, FIG. 2 is a view of the ischial contact member 1 installed on the chair 5 as viewed from above, and FIG. 3 is a view of the chair 5 as viewed from the side B. 4 is a side view of the sciatic contact member 1 installed on the chair 5 as viewed from the sciatic contact member 1, FIG. 5 is a diagram of the chair 5 viewed from the rear side D, and FIG. It is the figure seen from.
[0008]
The ischial contact member 1 is fixed to a flat seating surface 12 on the chair 5 in a pair of left and right positions with respect to the target axis 2 located in the center (the left and right sides of the target axis 2 in the center are line targets). The ischial contact member 1 is in the form of a triangular prism, and is divided into two on the diagonal line of a cube or regular cube. The angular position of the ischial contact member 1 is The two left and right ischial contact members 1 face each other toward the front side A (the left and right planes and the sloped seating surface 9 faces the direction of the target axis 2), and the flat and sloped seating surface 9 The angle 6 at which the extension line of the base 13 intersects is 40 degrees to 110 degrees (the ideal angle is 60 degrees), which is the angle 6 of the extension line of the base 13 of the seating surface 9 in FIGS. 4 is 20 degrees to 70 degrees (ideal angle is 35 degrees to 45 degrees) when viewed from the side. When the person sits down, the human bone is in contact with the sciatic contact member 1 and the angle and gravity apply pressure to the sacroiliac joint, and the posture is good. Therefore, when correcting the human body, the surgeon can correct with a light force.
[0009]
In addition, the shortest distance 8 between the left and right sciatic contact members 1 and the sciatic contact member 1 is 0.1 centimeters or more and 10 centimeters or less. The bearing surfaces 9 that are slopes face each other toward the target axis 2 (facing inside each other), and the bottom side 13 of the seat surface 9 that is the slope faces diagonally outward toward the front side A, Since the seating surface 9 has an angle 7, it can cover various widths of the left and right seat bones (the size of the buttocks) from children to adults.
[0010]
Then, the seat surfaces 9 that are the planes and the inclined surfaces of the left and right ischial contact members 1 as viewed from the rear side D face each other toward the target axis 2 (facing inside each other), and the seat surfaces 9 that are the inclined surfaces Since the base 13 is obliquely outward toward the front side A, the patient's pelvis is stuck and the back muscles are stretched when the patient sits on a seating surface 9 that is a slope, and the left and right sides as viewed from the rear side D. The sides 14 do not touch each other.
[0012]
In addition, a stable pelvis cannot be secured unless the size of the bottom side 13 of the seating surface 9 which is a slope is 5 cm or more, and a stable pelvis cannot be secured unless the size of the side 14 is 75 mm or more.
[0013]
In addition, the shape of the ischial contact member 1 that is a triangular prism is such that the directional angle 6 of the seating surface 9 that is an inclined surface, and the angle 7 viewed from the side surface of the seating surface 9 that is an inclined surface are not limited to the triangular prism. As long as the angle 6 of the seating surface 9 that is the slope to be described, the angle 7 seen from the side surface of the seating surface 9 that is the slope, and the position of the seating surface 9 that is the other slope can be secured, it may be in any form. .
[0014]
Although the seat surface 9 that is an inclined surface is not illustrated, there is a cover that covers the seat surface 9 that is an inclined surface, and a cushioning material exists between the seat surface 9 that is an inclined surface and the cover. Therefore, it is possible to remove the sense of incongruity of the human body bone, and to eliminate the sense of incongruity by making the seat surface 9 which is a flat and inclined surface into a curved line (concave shape) of the buttocks.
[0015]
Further, the chair leg 10 has a drive device for adjusting the height, although not illustrated, and the left and right ischial contact members 1 are the angle of the seating surface 9 which is a slope, the mutual distance, and the mutual FIG. The angle 6 shown in FIG. 5 has a drive device for driving each of the angles 6, and can be adapted to various patient spine heights and shapes.
[0016]
In addition, when correcting the patient's cervical spine or more, the surgeon corrects from a higher position so that it is easier to input force, and in order to deal with various patients, the step 3 is attached to the rear part (the step 3 is In order to make it easy to measure the degree of close contact with the patient, a gap 11 between the left and right step stands 3 is provided.
[0017]
And since the seating surface 9 which is a slope is a slope, in order to prevent it from slipping forward, the surface of the seating surface 9 which is a slope is provided with unevenness of 0.3 mm or more, or a slip stopper such as resin, rubber or the like is provided. It has a slip stopper such as a resin or rubber having unevenness of 0.3 mm or more to prevent the seated person's buttocks from slipping.
[0018]
Further, in order to move the seating surface 9 that is an inclined surface with the base 13 as a fulcrum, the base 13 of the seating surface 9 that is an inclined surface is a hinge, or An elastic body such as rubber or resin is attached and used as a branch member, and the base 13 of the seating surface 9 that is a slope is moved. The angle of the seating surface 9 is not illustrated, but the drive device is built in and the angle can be freely set. Can be changed to
[0019]
Further, when the seat surface 9 that is an inclined surface is moved with the symmetrical side 15 of the base 13 as a fulcrum, the base 13 is not fixed, and the symmetrical side 15 of the base 13 of the seat 9 that is an inclined surface is When the rear surface of the thigh is brought into contact with the surface, a hinge, or an elastic body such as rubber or resin is attached and used as a branch member, and the symmetrical side 15 of the base 13 is also moved. The angle of can be freely changed by the built-in drive device.
