<実施例1>
以下、本発明を具体化した実施例1を図1〜図10を参照して説明する。本実施例1の便器装置Aは、便鉢30を有する便器本体Bの上面に載置した状態で取り付けられるものである。便器装置Aは、上向きの座面12を有する便座10と、前向きの背当て面16を有する背もたれ15と、洗浄水を貯留するためのタンク31とを備えている。
<Example 1>
Hereinafter, Example 1 embodying the present invention will be described with reference to FIGS. 1 to 10. The toilet device A of the first embodiment is mounted on the upper surface of the toilet body B having the toilet bowl 30. The toilet device A includes a toilet seat 10 having an upward seating surface 12, a backrest 15 having a forward facing backrest surface 16, and a tank 31 for storing wash water.

<便座10>
便座10は、常には、便鉢30の上端面に載置された倒伏姿勢(図1〜4を参照)に置かれている。便座10は、その後端部の回動軸11(図5,6,8参照)を支点として倒伏姿勢に対して約90°立ち上がった起立姿勢(図8を参照)へ回動し得るようになっている。この回動軸11は、後述する背もたれ15の下端縁部15Eの近傍に配されている。
<Toilet seat 10>
The toilet seat 10 is always placed in a lying position (see FIGS. 1 to 4) placed on the upper end surface of the toilet bowl 30. The toilet seat 10 can rotate to an upright posture (see FIG. 8) that stands up about 90 ° with respect to the lying posture with the rotation shaft 11 (see FIGS. 5, 6 and 8) at the rear end as a fulcrum. ing. The rotating shaft 11 is arranged in the vicinity of the lower end edge portion 15E of the backrest 15 described later.

便座10の外面のうち倒伏姿勢で上向きとなる環状領域は、便座10に座った着座者(図示省略)の臀部を下から支える座面12となっている。便座10は、その座面12を含む全体が硬質の合成樹脂製である。また、便座10の座面12を含む外面全体が撥水性を有している。尚、以下の説明における方向は、便座10が倒伏姿勢である状態を基準として定義する。 Of the outer surface of the toilet seat 10, the annular region that faces upward in the prone position is the seat surface 12 that supports the buttocks of the seated person (not shown) sitting on the toilet seat 10 from below. The entire toilet seat 10, including the seat surface 12, is made of a hard synthetic resin. Further, the entire outer surface of the toilet seat 10 including the seat surface 12 has water repellency. The direction in the following description is defined based on the state in which the toilet seat 10 is in the prone position.

便座10の後端縁部10Eには、便座10の全幅に亘って上方へ突出する立上り部13が一体に形成されている。つまり、便座10の後端縁部10Eは上方へ立ち上がった形状をなしている。換言すると、立上り部13は、便座10の後端縁部10Eを構成する部位であり、立上り部13の上端縁13Eが、便座10の後端縁部10Eの上端縁となっている。立上り部13の前面は、座面12の後端縁部を斜め上後方へ延長させた形態の弧状凹面14となっている。つまり、座面12の後端縁部と弧状凹面14の下端縁部は、継ぎ目や隙間のないように滑らかに連続している。弧状凹面14は、立上り部13と同様、便座10の全幅に亘って形成されている。弧状凹面14は、着座者の臀部を斜め下後方から支える面として機能する。この弧状凹面14は、座面12の後端縁部のみを延長させた形態であるから、便座10のみに形成された部位であり、後述する背もたれ15には形成されていない。 The rear end edge portion 10E of the toilet seat 10 is integrally formed with a rising portion 13 projecting upward over the entire width of the toilet seat 10. That is, the rear end edge portion 10E of the toilet seat 10 has a shape that rises upward. In other words, the rising portion 13 is a portion constituting the rear end edge portion 10E of the toilet seat 10, and the upper end edge 13E of the rising portion 13 is the upper end edge of the rear end edge portion 10E of the toilet seat 10. The front surface of the rising portion 13 is an arc-shaped concave surface 14 in which the rear end edge portion of the seat surface 12 is extended diagonally upward and backward. That is, the rear end edge portion of the seat surface 12 and the lower end edge portion of the arcuate concave surface 14 are smoothly continuous without any seams or gaps. The arc-shaped concave surface 14 is formed over the entire width of the toilet seat 10, similarly to the rising portion 13. The arc-shaped concave surface 14 functions as a surface that supports the buttocks of the seated person from diagonally below and behind. Since the arc-shaped concave surface 14 is a form in which only the rear end edge portion of the seat surface 12 is extended, it is a portion formed only on the toilet seat 10, and is not formed on the backrest 15 described later.

便座10を前方から見た正面視において、図2に示すように、立上り部13の上端縁13E(即ち、弧状凹面14の上端縁)は、少なくとも幅方向中央部が水平、好ましくは、全幅に亘ってほぼ水平な直線状をなしている。また、便座10を上方から見た平面視において、弧状凹面14は、図7に示すように、左右方向における中央部を後方へ凹ませた形態で湾曲している。この湾曲形状は、弧状凹面14の高さ方向全領域に亘って設定されている。したがって、立上り部13の上端縁13Eの平面視形状も、左右方向における中央部を凹ませた形態で湾曲した形状である。 When the toilet seat 10 is viewed from the front, as shown in FIG. 2, the upper end edge 13E of the rising portion 13 (that is, the upper end edge of the arcuate concave surface 14) has at least a horizontal center portion in the width direction, preferably the entire width. It has an almost horizontal straight line. Further, in a plan view of the toilet seat 10 viewed from above, the arcuate concave surface 14 is curved in a form in which the central portion in the left-right direction is recessed rearward, as shown in FIG. This curved shape is set over the entire height direction of the arcuate concave surface 14. Therefore, the plan view shape of the upper end edge 13E of the rising portion 13 is also a curved shape in which the central portion in the left-right direction is recessed.

<背もたれ15>
背もたれ15は、タンク31の前面に固定して設けられている。背もたれ15は、全体として正面視形状が略方形の板状をなしている。背もたれ15の前面(正面)は、その全領域が背当て面16となっている。図9に示すように、背もたれ15は、発泡ウレタン等の弾性を有する弾性部材17と、金属製(硬質)のフレーム18とをインサート成形等によって一体化させた形態である。弾性部材17の表面(背当て面16)には、合成皮革等の可撓性を有するシート材(図示省略)が貼り付けられて一体化されている。シート材は、弾性部材17と一体となって弾性変形するようになっている。この背もたれ15(背当て面16)を構成する弾性部材17の材料は、便座10(座面12及び弧状凹面14)とは異なり、且つ便座10よりも柔らかい材料である。
<Backrest 15>
The backrest 15 is fixedly provided on the front surface of the tank 31. The backrest 15 has a substantially square plate shape as a whole when viewed from the front. The entire area of the front surface (front surface) of the backrest 15 is the back support surface 16. As shown in FIG. 9, the backrest 15 has a form in which an elastic member 17 having elasticity such as urethane foam and a metal (hard) frame 18 are integrated by insert molding or the like. A flexible sheet material (not shown) such as synthetic leather is attached to and integrated with the surface of the elastic member 17 (back support surface 16). The sheet material is elastically deformed integrally with the elastic member 17. The material of the elastic member 17 constituting the backrest 15 (back support surface 16) is different from the toilet seat 10 (seat surface 12 and arcuate concave surface 14) and is softer than the toilet seat 10.

背もたれ15の背当て面16は、便座10の弧状凹面14と同様、その高さ方向全領域に亘り、平面視において左右方向における中央部を凹ませた形態で湾曲している(図7を参照)。背もたれ15には、その背当て面16の下端部を前方へ突き出させた形態の膨出部20が形成されている。膨出部20の高さは、便座10に座った着座者の腰部と対応するように設定されている。膨出部20の前面(背当て面16)の平面視形状も、その高さ方向全領域に亘り、左右方向における中央部を凹ませた形態で湾曲した形状である。 Similar to the arcuate concave surface 14 of the toilet seat 10, the backrest surface 16 of the backrest 15 is curved in a shape in which the central portion in the left-right direction is recessed over the entire area in the height direction (see FIG. 7). ). The backrest 15 is formed with a bulging portion 20 in which the lower end portion of the backrest surface 16 is projected forward. The height of the bulging portion 20 is set so as to correspond to the lumbar region of the seated person sitting on the toilet seat 10. The plan view shape of the front surface (back support surface 16) of the bulging portion 20 is also a curved shape in which the central portion in the left-right direction is recessed over the entire area in the height direction.

背もたれ15のうち膨出部20の形成領域は、他の領域よりも後方へ弾性的に変位し易い形態となっている。膨出部20を後方へ変位し易くするための手段として、背もたれ15を弾性部材17を用いて構成しているとともに、弾性部材17の背面(後面)に肉抜き凹部21を形成することで膨出部20を他の領域よりも肉薄としている。この構成により、膨出部20は、前方から押されたときに、肉抜き凹部21内に進出しながら後方へ弾性的に変位するようになっている。 The formed region of the bulging portion 20 of the backrest 15 is in a form that is more likely to be elastically displaced rearward than the other regions. As a means for facilitating the rearward displacement of the bulging portion 20, the backrest 15 is configured by using the elastic member 17, and the bulging recess 21 is formed on the back surface (rear surface) of the elastic member 17 to bulge. The protrusion 20 is thinner than the other areas. With this configuration, when the bulging portion 20 is pushed from the front, the bulging portion 20 is elastically displaced rearward while advancing into the lightening recess 21.

背もたれ15には、その下端縁部15Eを上方又は後方へ弾性変形させることを可能にするための変形許容手段として溝部22が形成されている(図6、9を参照)。溝部22は、背もたれ15を構成する弾性部材17の背面(後面)をその下端縁に沿って幅方向に細長く凹ませた形態である。溝部22は、背もたれ15のほぼ全幅に亘って連続して形成されている。溝部22の上端縁22Eは、肉抜き凹部21の下端縁に対し近接して平行をなすように位置している。溝部22の下端縁は、背もたれ15の下端縁に対し近接して平行をなすように位置している。 The backrest 15 is formed with a groove portion 22 as a deformation allowing means for elastically deforming the lower end edge portion 15E upward or backward (see FIGS. 6 and 9). The groove portion 22 has a form in which the back surface (rear surface) of the elastic member 17 constituting the backrest 15 is elongated in the width direction along the lower end edge thereof. The groove portion 22 is continuously formed over almost the entire width of the backrest 15. The upper end edge 22E of the groove portion 22 is located so as to be close to and parallel to the lower end edge of the lightening recess 21. The lower end edge of the groove 22 is positioned so as to be close and parallel to the lower end edge of the backrest 15.

背もたれ15のうち溝部22が形成されている下端縁部15Eは、他の領域よりも肉薄となっている。そして、肉薄となった背もたれ15の下端縁部15Eは、上方や後方へ弾性変形し易くなっている。また、弾性部材17の背面には、溝部22内に収容されて溝部22の上端縁と下端縁とを連結するリブ23が一体に形成されている(図6,9を参照)。リブ23は、上下方向に細長く、背もたれ15の幅方向に間隔を空けた複数位置に配されている。リブ23を形成したことにより、背もたれ15の下端縁部15Eが下方へ垂れ下がって型崩れすることを防止している。 The lower end edge portion 15E of the backrest 15 on which the groove portion 22 is formed is thinner than the other regions. The lower end edge portion 15E of the thin backrest 15 is likely to be elastically deformed upward or backward. Further, on the back surface of the elastic member 17, ribs 23 housed in the groove portion 22 and connecting the upper end edge and the lower end edge of the groove portion 22 are integrally formed (see FIGS. 6 and 9). The ribs 23 are elongated in the vertical direction and are arranged at a plurality of positions spaced apart in the width direction of the backrest 15. By forming the rib 23, the lower end edge portion 15E of the backrest 15 is prevented from hanging downward and losing its shape.

背もたれ15を構成するフレーム18は、図9に示すように、弾性部材17内に大部分が埋設された方形枠部24と、方形枠部24から後方へ突出して背もたれ15から露出した複数の固定用機能部25とを一体化したものである。方形枠部24は、背もたれ15よりも一回り小さい大きさであり、背もたれ15が型崩れするのを防止する手段として機能する。方形枠部24を構成する水平な下枠部26は、肉抜き凹部21の下端縁と溝部22の上端縁との境界に沿うように配されている。そして、上記のリブ23の上端は、下枠部26に近接した位置に配されている。溝部22とリブ23が形成されている弾性部材17は、下枠部26と一体化されているので、リブ23の上端が所定の高さに保たれる。したがって、溝部22や背もたれ15の下端縁部15Eが下方へ垂れ下がるように変形する虞はない。 As shown in FIG. 9, the frame 18 constituting the backrest 15 includes a square frame portion 24 in which most of the frame 18 is embedded in the elastic member 17, and a plurality of fixed frames protruding rearward from the square frame portion 24 and exposed from the backrest 15. It is integrated with the functional unit 25. The square frame portion 24 has a size one size smaller than that of the backrest 15, and functions as a means for preventing the backrest 15 from losing its shape. The horizontal lower frame portion 26 constituting the square frame portion 24 is arranged along the boundary between the lower end edge of the lightening recess 21 and the upper end edge of the groove portion 22. The upper end of the rib 23 is arranged at a position close to the lower frame portion 26. Since the elastic member 17 on which the groove portion 22 and the rib 23 are formed is integrated with the lower frame portion 26, the upper end of the rib 23 is maintained at a predetermined height. Therefore, there is no possibility that the groove portion 22 and the lower end edge portion 15E of the backrest 15 are deformed so as to hang downward.

便座10の後端縁部10Eの上端縁(つまり、立上り部13の上端縁13E)と背もたれ15の下端縁部15Eは、上下方向において近接した位置関係で配置されている。便座10の後端縁部10Eの上面10Sは、側面視形状が略円弧形となっている。また、図5,6に示すように、便座10の後端縁部10Eの上面10Sと、背もたれ15の下端縁部15Eの下面15Sは、上下に近接して対向する位置関係となっている。そして、側面視において、座面12から弧状凹面14を経て背当て面16に至る領域は、極端な凹凸が存在しないような形態で連続している。この座面12と弧状凹面14と背当て面16は、便座10に座った着座者の臀部と腰部と背中を支えるための支え面として機能する。 The upper end edge of the rear end edge portion 10E of the toilet seat 10 (that is, the upper end edge 13E of the rising portion 13) and the lower end edge portion 15E of the backrest 15 are arranged in a close positional relationship in the vertical direction. The upper surface 10S of the rear end edge portion 10E of the toilet seat 10 has a substantially arc shape in terms of side view. Further, as shown in FIGS. 5 and 6, the upper surface 10S of the rear end edge portion 10E of the toilet seat 10 and the lower surface 15S of the lower end edge portion 15E of the backrest 15 are in a positional relationship close to each other in the vertical direction. Then, in the side view, the region from the seat surface 12 through the arcuate concave surface 14 to the back support surface 16 is continuous in such a form that there is no extreme unevenness. The seat surface 12, the arcuate concave surface 14, and the back support surface 16 function as support surfaces for supporting the buttocks, lumbar region, and back of the seated person sitting on the toilet seat 10.

<肘掛け27>
本実施例の便器装置Aは、左右対称な一対の肘掛け27を有している。肘掛け27は、タンク31の左右両側面に支持されており、背もたれ15の側縁から前方へ突出した形態である。肘掛け27は、金属製の心材28を発泡ウレタン等の弾性支持部材29で包囲した形態である(図10を参照)。肘掛け27の弾性支持部材29の素材は、背当て面16の素材(弾性部材17)よりは少し硬めのものが選択されているが、着座者が肘や腕を載せたときに不快感を感じない程度の弾力は有している。
<Arrest 27>
The toilet bowl device A of this embodiment has a pair of symmetrical armrests 27. The armrests 27 are supported on both the left and right sides of the tank 31, and project forward from the side edges of the backrest 15. The armrest 27 has a metal core material 28 surrounded by an elastic support member 29 such as urethane foam (see FIG. 10).
