本考案は、腰掛具に関し、特に、和室等で使用される正座椅子に関する。   The present invention relates to a stool and, more particularly, to a sitting chair used in a Japanese-style room or the like.

正座椅子は、座板に腰掛けるとともに膝下を該座板の下にくぐらせて正座姿勢を保つことがきるように構成した腰掛具であり、正座時に生じる足の痛みを緩和し、しびれの発生を防止でき、快適な正座姿勢を持続することを可能にするものである。   A seating chair is a stool configured to be able to maintain a sitting posture by sitting on a seat plate and passing a lower part of the knee under the seat plate. This makes it possible to maintain a comfortable sitting posture.

従来の正座椅子は、使用者が正座時に臀部を載せる座板と、該座板の両側部に設けられ該座板を支持する脚部とから構成される。   2. Description of the Related Art A conventional sitting chair is composed of a seat plate on which a user places his buttocks when sitting down, and legs provided on both sides of the seat plate to support the seat plate.

また、使用者の体形や使用情況などに応じて座板の高さや傾斜角度を使用者により調整可能に構成した正座椅子も知られている(特許文献1参照)。   Further, there is also known a sitting chair in which a height and an inclination angle of a seat plate can be adjusted by a user according to a user's body shape and usage conditions (see Patent Document 1).

図7は特許文献1記載の正座椅子を示す図である。この正座椅子は、水平方向に延びる座板10と、その両横側縁に縦に取り付けて座板10を支える長方形の2枚の足板20から構成される。座板10の両横側縁には該座板10と一体で下方に延びるリブ30を有し、該リブ30の端部には大小の2つの凹部の組み合わせでなるくびれ40が前後方向に2個設けられており、2枚の足板20には前記リブ30との取り付け時に前記くびれに対応する位置にネジ止め用の上下2個のオニメナット50が埋め込まれている。   FIG. 7 is a diagram showing a sitting chair described in Patent Document 1. This sitting chair is composed of a horizontally extending seat plate 10 and two rectangular foot plates 20 which are vertically attached to both lateral side edges to support the seat plate 10. On both lateral edges of the seat plate 10, there are provided ribs 30 extending downward integrally with the seat plate 10, and at the end of the rib 30, a narrow portion 40 made of a combination of two large and small concave portions is provided in the front-back direction.

It is performed by combining. The height and the inclination angle can be adjusted in several steps by changing the combination of the fixing of any one of the upper and lower onyme nuts 60 and the one of the large and small constrictions 40.
JP 2001-145543 A

従来の正座椅子は座板が床と平行に脚部により支持されるように構成されるものが一般的であるが、座板が床面にたいして平行に位置するように構成されたものは、正座姿勢によってつくりだされる膝の屈曲角度、もしくは腿と地面との角度に対応しないことにより、長時間の使用時に足の痛みが生じ快適に正座姿勢を保つことが困難になるという問題がある。   Conventional seat chairs are generally configured so that the seat plate is supported by the legs in parallel with the floor, but those configured so that the seat plate is positioned parallel to the floor surface are common seats. By not responding to the knee flexion angle or the angle between the thigh and the ground created by the posture, there is a problem in that the foot becomes painful when used for a long time, making it difficult to maintain a comfortable sitting posture.

また、特許文献1記載の正座椅子は座板の上面を床面に対し傾斜角度を持たせることが可能であるが、かかる正座椅子では座板の上面の傾斜角度が使用者の上体の動きかかわらず固定的であるから、使用時にとり得る姿勢が固定され上体の運動を制約し長時間にわたり使用する場合にはやはり次第に苦痛が生じるという問題がある。   Further, in the straight seat chair described in Patent Document 1, the upper surface of the seat plate can be inclined with respect to the floor surface. Regardless, since it is fixed, there is a problem that the posture that can be taken at the time of use is fixed, and the use of the body for a long period of time is restricted by the movement of the upper body.

(考案の目的)
本考案の目的は、以上のような問題を解決するものであり、使用者の姿勢によりつくりだされる膝の屈曲角度や腿と床面との角度に適合した正座椅子を提供することにある。
(Purpose of the invention)
An object of the present invention is to solve the above-described problems, and to provide a seating chair suitable for a bending angle of a knee or an angle between a thigh and a floor surface created by a posture of a user. .

本考案の目的は、長時間の間しびれをきらすことなく楽に座っていられるとともに、簡単な構造により座板の傾斜角度が上体の動きに応じて自動的に変化可能な正座椅子を提供することにある。   It is an object of the present invention to provide a sitting chair which can be comfortably seated for a long time without numbness and which can easily change the inclination angle of a seat plate according to the movement of the upper body with a simple structure. It is in.

本考案の他の目的は、正座の姿勢変更に自由度をもたらし、垂直な正座姿勢から前傾姿勢までの上体の動きに適合する使用感のよい正座椅子を提供することにある。   It is another object of the present invention to provide a seating chair that gives a degree of freedom in changing the sitting position and that is suitable for use in the movement of the upper body from a vertical sitting position to a forward leaning position.

本考案は、座板と該座板の両側部に設けられ座板を支持する脚板とを備える正座椅子において、前記脚板の床面側の端部は、後方に座板の面の前後方向に対する所定角度の傾斜を有するとともに、前方に前記角度より大きい角度の傾斜部を有し、又は前方に前記角度より大きい角度の円弧状の傾斜部を有し、又は後方から前方にかけて順次傾斜角度が大きくなる円弧状の傾斜部を有し、又は前方に弾性部材を有し前下がりでなることを特徴とする。   The present invention relates to a front seat having a seat plate and a leg plate provided on both sides of the seat plate to support the seat plate, wherein the end portion of the leg plate on the floor surface side is rearward with respect to the front-back direction of the surface of the seat plate. With a predetermined angle of inclination, having a slope of an angle larger than the angle in front, or having an arc-shaped slope of an angle larger than the angle in front, or gradually increasing the inclination angle from back to front It is characterized by having an arc-shaped inclined portion, or having an elastic member at the front and falling forward.

(作用)
腰掛具を使用しない場合につくりだされる自然な座姿勢のみならず、上体の前傾姿勢など、上体の移動時の膝の屈折角度、もしくは腿と床面との適宜の角度で腰掛けることができ、上体の動きに応じた座面の複数の前下がりの傾斜により座板が前方に自動的に傾斜する。
(Action)
Sit not only in the natural sitting posture created when the stool is not used, but also at the appropriate bending angle of the knee when moving the upper body, or the appropriate angle between the thigh and the floor surface, such as the forward leaning posture of the upper body The seat plate is automatically tilted forward by a plurality of downward slopes of the seat surface in response to the movement of the upper body.

本考案によれば、座板が単に前下がりの状態を保つのではなく、使用者の上体の姿勢に応じて前下がりの程度が自動的に変化することから、膝への負担がなく安定しかつ楽な正座姿勢から上体を前傾し跪いた姿勢までの座板の連続的な傾斜角度が実現でき、姿勢の固定化による苦痛が緩和され楽な正座を可能とするのみならず、正座での日常生活で極めて使い勝手がよく、茶道、華道、書道等、上体の運動を伴う状況での正座の補助椅子としても好適である。   According to the present invention, the seat plate does not simply maintain the forward-downward state, but the degree of forward-downward changes automatically according to the posture of the upper body of the user, so that there is no burden on the knees and stable. It is possible to realize the continuous inclination angle of the seat plate from the easy and easy sitting position to the posture in which the upper body leans forward and kneels down, not only the pain due to the fixed posture is eased, but also easy sitting is possible, It is extremely easy to use in everyday life in the sitting position, and is also suitable as an auxiliary chair for the sitting position in situations involving upper body movements such as tea ceremony, flower arrangement, and calligraphy.

また、構造的に簡単でありコスト増を抑え連続的な傾斜の自動調節を可能とする。脚部に弾性体(弾性部材)を設ける場合には、より柔軟な傾斜角度の自動調整が可能となる。脚部は傾斜を与える端部を除きその形状は任意であり板面を最小限に留めることにより美観を損なうことがない正座椅子の実現が可能である。   In addition, it is structurally simple, and enables an automatic adjustment of a continuous inclination while suppressing an increase in cost. When an elastic body (elastic member) is provided on the leg portion, more flexible automatic adjustment of the inclination angle is possible. The shape of the legs is arbitrary except for the end portion that gives the inclination, and by minimizing the plate surface, it is possible to realize a sitting chair without impairing the aesthetic appearance.

本考案の正座椅子によれば、座板に予め所定角度の前下がりの傾斜が与えられているとともに、座板に腰掛けた際の体重のかけ方に応じて更に傾斜の角度が変化するため、座姿勢での使用にかかわらず、浴室での足を伸ばした状態での使用、ガーデニングや雑草取り、胡座での使用等にも好適である。   According to the seat chair of the present invention, the seat plate is given a forward inclination of a predetermined angle in advance, and the angle of the inclination further changes according to the weight applied when sitting on the seat plate. Regardless of use in a sitting posture, it is also suitable for use in a bathroom with legs extended, gardening, weed removal, use in crosses, and the like.

次に、本考案の正座椅子の実施の形態について、以下図面を参照して詳細に説明する。
(第1の実施の形態)
図1は本考案の第1の実施の形態を示す図であり、図1(a)は腰掛具の上方斜視図、図1(b)は腰掛具の側面図である。
Next, an embodiment of the sitting chair of the present invention will be described in detail below with reference to the drawings.
(First Embodiment)
FIG. 1 is a view showing a first embodiment of the present invention. FIG. 1A is an upper perspective view of a stool, and FIG. 1B is a side view of the stool.

本実施の形態の正座椅子の基本構造は、略長方形の座板1と該座板1の短辺側の2辺に直角方向に取り付けた2枚の脚板2、3から構成される。   The basic structure of the sitting chair according to the present embodiment includes a substantially rectangular seat plate 1 and two leg plates 2 and 3 attached to two short sides of the seat plate 1 at right angles.

また、脚板2、3は、座板1に上体の直立に近い姿勢で腰掛けた時に座板1が前下がりとなるように、床面に接する端部側の後方において、座板1に取り付けられる端部側に対し、正座時に足腰の屈曲による臀部から膝裏まで傾斜角度に対応する略直線状の所定傾斜が形成された形状構造を備える。この場合、下肢、特に、膝下は床面から僅かに隙間が形成されるなど、脚板の高さにより膝に上体の大きな重みが掛からないようにすると好適である。   Further, the leg plates 2 and 3 are attached to the seat plate 1 at the rear of the end portion in contact with the floor surface so that the seat plate 1 is lowered forward when sitting on the seat plate 1 with the body close to an upright posture. A shape structure in which a substantially linear predetermined inclination corresponding to the inclination angle from the buttocks to the sole of the knee due to the bending of the legs and hips when sitting straight is formed on the end side. In this case, it is preferable that a large weight of the upper body is not applied to the knee by the height of the leg plate, for example, a slight gap is formed from the floor surface in the lower limbs, particularly below the knee.

更に、脚板2、3の床面に接する端部側の前方においては、前記略直線状の傾斜する端部から延長する単一ないし順次異なる複数の曲率でなるR形状部が形成された傾斜部又は円弧状傾斜部4の形状構造を備える。   Furthermore, in front of the end portions of the leg plates 2 and 3 that are in contact with the floor surface, an inclined portion formed with a single or sequentially different plurality of R-shaped portions extending from the substantially straight inclined end portion is formed. Or, it has a shape structure of the arc-shaped inclined portion 4.

本実施の形態においては、前記略直線状の所定傾斜部分は脚板2、3の端部の長さ方向の後方から略2/3までの範囲に形成され、R形状部4は2つの曲率の曲面部分でなり脚板2、3の端部の同長さ方向の前方から略1/3までの範囲に形成される。   In the present embodiment, the substantially linear predetermined inclined portion is formed in a range from the rear in the length direction of the end portions of the leg plates 2 and 3 to approximately 2/3, and the R-shaped portion 4 has two curvatures. It is a curved portion and is formed in a range from the front of the ends of the leg plates 2 and 3 in the same length direction to approximately 1/3.

本実施の形態の脚部2、3の構造の機能は以下のとおりである。脚板2、3の床面側の端部における傾斜角度を形成した後方の直線部は、座板1に略直立の姿勢で腰掛けた時に使用者の正座による自然な臀部から下肢にかけての床面に対する傾斜に適合する前下がりの座板1の角度を確保するものであり、また、床面に接する端部側の前方の2つの異なる曲率でなるR形状等が形成された曲線部は、略直立姿勢の腰掛け状態から上体の重心を移動する前傾姿勢に移行した場合に、脚板2、3の後方に床との間の隙間を容易に生ぜしめ、座板1が前傾姿勢の程度に応じたより大きな傾斜角度、つまり、より大きな前下がりの傾斜が自動的に形成されることを可能とし、この時、上体の重心移動と相まって膝下が容易に床面に接し座板の前下がりの程度に応じて体重の一部から殆どまでを膝で支えることを可能とし、正座状態から跪くような通常の生活行動から各種の作法を要する行動まで殆どの行動を容易にとることを可能とするものである。   The function of the structure of the legs 2 and 3 of the present embodiment is as follows. The rear straight portion that forms the inclination angle at the floor-side end of the leg plates 2 and 3 is positioned with respect to the floor from the natural buttocks to the lower limbs when the user sits on the seat plate 1 in a substantially upright posture. The curved portion formed with two different curvatures in front of the end portion in contact with the floor is formed to be substantially upright, which secures the angle of the seat plate 1 lowered forward in conformity with the inclination. When shifting from the sitting state of the posture to the forward leaning posture in which the center of gravity of the upper body is moved, a gap between the floor and the floor is easily created behind the leg plates 2 and 3, and the seat plate 1 is moved to the degree of the forward leaning posture. In accordance with the greater inclination angle, that is, the greater downward inclination, it is possible to automatically form, and at this time, together with the movement of the center of gravity of the upper body, the lower part of the knee easily touches the floor surface and the lowering of the front of the seat plate Depending on the degree, it is possible to support part to most of the weight with the knee And it is intended to allow to take facilitate most behavior from normal life activities, such as kneeling from sit until action requiring various manners.

本考案の正座椅子の具体的な材料、寸法は以下のとおりである。座板1及び脚板2、3を木製とし、標準的な成人を想定すると、腰掛時に左右方向の辺(長辺側)の寸法を約420mm、同前後方向の辺(短辺側)の寸法を約152mmの長方形とする。脚板2、3は横方向は約150mm、縦方向は使用時に後方となる側を約140mmの略台形の平板とする。   The specific materials and dimensions of the sitting chair of the present invention are as follows. Assuming a standard adult, the seat plate 1 and the leg plates 2 and 3 are made of wood, and the size of the side in the left-right direction (long side) is about 420 mm and the size of the side in the front-rear direction (short side) when sitting down. It is a rectangle of about 152 mm. Each of the leg plates 2 and 3 is a substantially trapezoidal plate having a width of about 150 mm in the horizontal direction and a length of about 140 mm on the rear side in use in the vertical direction.

脚板2、3の床面側の端部は、後方の略2/3の範囲(100mm)を座板の面の前後方向に対する11°ないし13°、好適には略12°の傾斜を形成するとともに、同前方には略1/3の範囲(50mm)に後方から続き曲率半径100(mm)Rないし200(mm)RのR形状部、好適には略150(mm)R(R1)のR形状部を形成する。また、これに続き20(mm)Rないし50(mm)R、好適には30(mm)R(R2)の丸みを有するR形状部を形成する。   The floor-side ends of the leg plates 2 and 3 form an inclination of 11 ° to 13 °, preferably approximately 12 ° with respect to the front-rear direction of the surface of the seat plate in an approximately 略 rearward range (100 mm). At the same time, an R-shaped portion having a radius of curvature of 100 (mm) R to 200 (mm) R, preferably approximately 150 (mm) R (R1), is provided at the front in a range of approximately 1/3 (50 mm) from the rear. An R-shaped part is formed. Subsequently, an R-shaped portion having a roundness of 20 (mm) R to 50 (mm) R, preferably 30 (mm) R (R2) is formed.

座板と脚板とは木ネジにより固定し、強化のため断面が直角三角形で長さが約145mmの図示しない力木を一対用いて座板1の両横端の下部の脚部2、3の内側にその斜面が内下方を向くように取り付ける。   The seat plate and the leg plate are fixed with wood screws, and for strengthening, a pair of unillustrated power woods having a right-angled triangle and a cross section of approximately 145 mm in length is used for strengthening the lower leg portions 2 and 3 at both lateral ends of the seat plate 1. Attach so that the slope faces inward and downward.

(第2の実施の形態)
第1の実施の形態においては、脚板の端部の前部にR形状部を設けた例を示したが、この構造は本考案の前述の技術思想に則り上体の重心の移動に応じた座板の前下がりの傾斜角度が可変になれば良いのであるから、R形状に限られるものではないことは明らかである。
(Second embodiment)
In the first embodiment, an example is shown in which an R-shaped portion is provided at the front of the end of the leg plate, but this structure is adapted to the movement of the center of gravity of the upper body according to the above-described technical idea of the present invention. It is clear that the present invention is not limited to the R-shape, since it is only necessary that the inclination angle of the seat plate in the front downward direction can be changed.

図2は本考案の第2の実施の形態を示す図であり、図2(a)は腰掛具の上方斜視図、図2(b)は腰掛具の側面図である。   2A and 2B are views showing a second embodiment of the present invention, wherein FIG. 2A is an upper perspective view of the stool, and FIG. 2B is a side view of the stool.

本実施の形態においては、脚板2、3の前部の形状を座板1に対し後部の傾斜角度に対し、より大きな傾斜角度を有するように切り欠き状の傾斜部5を形成した形状構造を備えるものである。本例の場合も図1に示す正座椅子と同様の寸法を適用可能である。   In the present embodiment, a shape structure in which the notch-shaped inclined portion 5 is formed so that the front portions of the leg plates 2 and 3 have a larger inclination angle with respect to the inclination angle of the rear portion with respect to the seat plate 1. It is provided. Also in the case of this example, the same dimensions as those of the sitting chair shown in FIG. 1 can be applied.

(第3の実施の形態)
図3は、本考案の第3の実施の形態を示す図である。図3(a)では脚板の前部形状を図2に示す切り欠き状の形状とし、当該部分に上体の重心移動により変形する弾性力を有する弾性部材6を固定した形状構造を備える。本実施の形態によれば、上体の重心移動により前部弾性部材が変形し、座板の自然な前下がりの前傾角度が実現されるという利点がある。
(Third embodiment)
FIG. 3 is a diagram showing a third embodiment of the present invention. In FIG. 3A, the leg plate has a notch shape as shown in FIG. 2, and has a shape structure in which an elastic member 6 having an elastic force that is deformed by the movement of the center of gravity of the upper body is fixed to the portion. According to the present embodiment, there is an advantage that the front elastic member is deformed by the movement of the center of gravity of the upper body, and a natural forward tilt angle of the seat plate is naturally lowered.

図3(b)では、脚板の前部形状を切り欠き状の形状に代えて段差を有する形状としたものである。脚板の端部は弾性部材6を有する範囲を含めて直線状としているが、使用者の上体の移動により弾性部材6の変形により自動的な傾斜角度の変化が実現される。   In FIG. 3B, the front portion of the leg plate has a stepped shape instead of the cutout shape. Although the end of the leg plate is linear including the range having the elastic member 6, the inclination angle is automatically changed by the deformation of the elastic member 6 due to the movement of the upper body of the user.

弾性部材6の弾性材料としては、例えば、ゴム、シリコンゴム、プラスチック材料等が利用可能であり、前部の切り欠き状箇所への固着は、弾性材料を成型して切り欠き状箇所に設けた溝に嵌着する等の方法が採用可能である。   As the elastic material of the elastic member 6, for example, rubber, silicon rubber, plastic material, or the like can be used, and the elastic material 6 is fixed to the notch-shaped portion at the front by molding the elastic material and providing the cutout-shaped portion. A method such as fitting in a groove can be adopted.

(第4の実施の形態)
図4は本考案の第4の実施の形態を示す図である。第2の実施の形態では脚部の床面側の端部の形状を傾斜する直線状の傾斜部とR形状部との組み合わせで構成したが、図4(a)に示すように脚板の端部を後方の一部を除き全体的に湾曲する形状(湾曲部)7として構成することにより、リラックスして使用するローリングチェアのように姿勢を揺動できる正座椅子を構成することが可能である。
(Fourth embodiment)
FIG. 4 is a diagram showing a fourth embodiment of the present invention. In the second embodiment, the shape of the end of the leg on the floor side is formed by a combination of a linear inclined portion and an R-shaped portion. However, as shown in FIG. By configuring the portion as a shape (curved portion) 7 that is entirely curved except for a portion at the rear, it is possible to configure a sitting chair that can swing its posture like a rolling chair that is used relaxedly. .

図4(b)は軽量化ないし外観上の工夫を施したものであり、正座椅子の使用を脚板の床面側の端部に脚板中央に大きい開口8を設けている。軽量化により前下がりの変化を容易にし、また側部方向からの見栄えを改善し使用者の抵抗感、違和感を少なくし、周囲からも意識されないように構成している。また、必要により座板及び脚板に透明材料を採用し又はクッションマット等の装飾布を積層し美観を損なわないよう工夫を加えることができる。開口を有する脚板の形状は他の実施の形態に適用可能であることは明らかである。   FIG. 4 (b) shows a lighter weight or an improved device for appearance. A large opening 8 is provided at the center of the leg plate at the end of the leg plate on the floor side when using a sitting chair. The weight is reduced to make it easier to change forward, and the appearance from the side is improved to reduce the resistance and uncomfortable feeling of the user, so that the surroundings are not conscious. If necessary, a transparent material may be used for the seat plate and the leg plate, or a decorative cloth such as a cushion mat may be laminated to add a device so as not to impair the aesthetic appearance. Obviously, the shape of the leg plate having the opening is applicable to other embodiments.

(第5の実施の形態)
以上に実施の形態では、座板と脚板との間に調整手段を設けない例を示しているが、本考案は調整手段を有する正座椅子にも適用可能であることは言うまでもない。
(Fifth embodiment)
As described above, the embodiment shows an example in which the adjusting means is not provided between the seat plate and the leg plate. However, it is needless to say that the present invention can be applied to a sitting chair having the adjusting means.

図7は第5の実施の形態を示す図である。図8に示すものと同様に、座板はくびれを設けたリブを有する構造とし、リブと脚板とをオニメナットとコインボルトを利用して固定する構造を備え、更に脚板の一方の側にR形状部を設けた構造を備える。第5の実施の形態においてもR形状部に代えて直線状の傾斜部や弾性部材を設けるように構成することが可能であることは明らかである。   FIG. 7 is a diagram showing a fifth embodiment. Like the one shown in FIG. 8, the seat plate has a structure having a rib provided with a constriction, a structure in which the rib and the leg plate are fixed by using an onime nut and a coin bolt, and further, an R shape is provided on one side of the leg plate. It has a structure provided with a part. It is clear that the fifth embodiment can also be configured to provide a linear inclined portion or an elastic member instead of the R-shaped portion.

以上、各種実施の形態について説明したが、本考案はこれらの実施の形態に限られるものではなく、安定した正座姿勢から上体の動きに応じて座板の連続的な傾斜角度が実現できるところの実用新案登録請求の範囲記載の脚板の傾斜構造を備える限り各種の変形及び変更が可能であることは明らかである。   Although various embodiments have been described above, the present invention is not limited to these embodiments, and a position where a continuous inclination angle of the seat plate can be realized from a stable sitting position according to the movement of the upper body. It is obvious that various modifications and changes are possible as long as the leg plate has the inclined structure described in the claims of the present invention.
