Japanese Patent No. 3434604

ところで、前記のような３分割タイプの便器において、ボウル部の支持が少ないと、ボウル部に作用する耐衝撃性が低下しやすいという問題があった。   By the way, in the three-part type toilet as described above, there is a problem that if the support of the bowl portion is small, the impact resistance acting on the bowl portion tends to be lowered.

本発明は、前記問題を解消するためになされたもので、ボウル部に作用する耐衝撃性を向上させるとともに、スカート部によるボウル部の支持が安定するように工夫した便器を提供することを目的とするものである。   The present invention has been made to solve the above-described problems, and it is an object of the present invention to provide a toilet devised so as to improve the impact resistance acting on the bowl portion and to stabilize the support of the bowl portion by the skirt portion. It is what.

前記課題を解決するために、本発明は、スカート部と、スカート部の内部に配置されるボウル部と、スカート部の上部に接合されるリム部とに３分割された便器であって、前記スカート部の内面に、ボウル部の裏面に沿うように突出するボウル支持リブを形成し、ボウル支持リブでボウル部の裏面を支持するようにし、このボウル支持リブは、スカート部の平面視において、スカート部の中心から放射状となるように複数個を形成していることを特徴とする便器を提供するものである。 In order to solve the above problems, the present invention is a toilet bowl divided into three parts: a skirt part, a bowl part arranged inside the skirt part, and a rim part joined to the upper part of the skirt part, Formed on the inner surface of the skirt portion is a bowl support rib that protrudes along the back surface of the bowl portion, and the bowl support rib supports the back surface of the bowl portion . A toilet is provided in which a plurality of skirts are formed radially from the center of the skirt .

スカート部によるボウル部の支持をより安定させるために、前記ボウル支持リブの隣り合う隙間に発泡材を充填することが好ましい。   In order to further stabilize the support of the bowl portion by the skirt portion, it is preferable to fill a gap between adjacent bowl support ribs with a foam material.

スカート部によるボウル部の支持をより安定させるために、前記ボウル支持リブのボウル受け部に発泡成形体を配置することが好ましい。   In order to further stabilize the support of the bowl portion by the skirt portion, it is preferable to dispose the foam molded body in the bowl receiving portion of the bowl support rib.

寒冷地における便器内の残水の凍結を防止するために、前記発泡成形体は、少なくともボウル部の貯水面以下に位置することが好ましい。   In order to prevent freezing of the residual water in the toilet in a cold region, the foamed molded body is preferably located at least below the water storage surface of the bowl portion.

本発明によれば、スカート部の内面に形成したボウル支持リブでボウル部の裏面を支持するようにしたから、ボウル部に作用する垂直方向の衝撃荷重と水平方向の衝撃荷重とに対する耐衝撃性が向上するとともに、スカート部によるボウル部の支持が安定して、接合時の位置ズレが発生しにくくなる。
また、複数個のボウル支持リブを形成することにより、耐衝撃性がより向上するとともに、スカート部によるボウル部の支持がより安定するようになる。
さらに、ボウル支持リブを放射状に形成することにより、少ない個数で耐衝撃性がより向上するとともに、スカート部によるボウル部の支持がより安定するようになる。 According to the present invention, since the back surface of the bowl portion is supported by the bowl support rib formed on the inner surface of the skirt portion, the impact resistance against the vertical impact load and the horizontal impact load acting on the bowl portion. And the support of the bowl part by the skirt part becomes stable, and the positional deviation at the time of joining is less likely to occur.
Further, by forming a plurality of bowl support ribs, the impact resistance is further improved, and the support of the bowl part by the skirt part becomes more stable.
Furthermore, by forming the bowl support ribs radially, the impact resistance can be further improved with a small number, and the support of the bowl part by the skirt part becomes more stable.

以下、本発明を実施するための最良の形態について、図面を参照しながら詳細に説明する。なお、背景技術と同一構成・作用の箇所は、同一番号を付して詳細な説明を省略する。   Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings. Note that portions having the same configuration and operation as those of the background art are denoted by the same reference numerals, and detailed description thereof is omitted.

図１（ａ）は便器の側面断面図、図１（ｂ）はスカート部１のボウル支持リブ１ｃの要部斜視図、図２（ａ）はスカート部の平面図、図２（ｂ）は図２（ａ）のI−I線断面図、図２（ｃ）は図２（ｂ）のII−II線断面図である。   1 (a) is a side sectional view of the toilet, FIG. 1 (b) is a perspective view of the main part of the bowl support rib 1c of the skirt portion 1, FIG. 2 (a) is a plan view of the skirt portion, and FIG. 2A is a cross-sectional view taken along the line I-I in FIG. 2A, and FIG. 2C is a cross-sectional view taken along the line II-II in FIG.

図１（ａ）において、スカート部１の内部にボウル部２が配置されるとともに、スカート部１の上部にリム部３が接合されている。このリム部３は、上辺部３ａと内辺部３ｂとで形成して、スカート部１の上端部１ａをリム部３の上辺部３ａの下面に当接させて接合するとともに、ボウル部２の上端部２ａをリム部３の内辺部３ｂの底部３ｃに接合している。   In FIG. 1A, the bowl portion 2 is disposed inside the skirt portion 1, and the rim portion 3 is joined to the upper portion of the skirt portion 1. The rim portion 3 is formed by an upper side portion 3a and an inner side portion 3b, and the upper end portion 1a of the skirt portion 1 is brought into contact with and joined to the lower surface of the upper side portion 3a of the rim portion 3, and the bowl portion 2 The upper end 2 a is joined to the bottom 3 c of the inner side 3 b of the rim 3.

スカート部１の内面には、ボウル部２の裏面２ｂに沿うように突出するボウル支持リブ１ｃを一体形成している。このボウル支持リブ１ｃは、図２（ａ）〜（ｃ）のように、スカート部１の平面視において、例えばスカート部１の中心から放射状となるように複数個（本例では８個）を形成して、ボウル支持リブ１ｃの上縁部をボウル部２の裏面２ｂに沿う湾曲形状のボウル受け部１ｄに形成することで、ボウル支持リブ１ｃでボウル部２の裏面２ｂを支持するようにしている。各ボウル支持リブ１ｃの下端部は、便器の設置フロアに接するようになる。これにより、スカート部１を便器の設置フロアに安定して置くことができ、スカート部１が撓みにくくなるとともに、ボウル部２の支持も安定するようになる。   A bowl support rib 1 c that protrudes along the back surface 2 b of the bowl part 2 is integrally formed on the inner surface of the skirt part 1. As shown in FIGS. 2 (a) to 2 (c), the bowl support rib 1c includes a plurality of (eight in this example) so as to radiate from the center of the skirt 1 in a plan view of the skirt 1, for example. The upper edge of the bowl support rib 1c is formed in a curved bowl receiving portion 1d along the back surface 2b of the bowl portion 2, so that the back surface 2b of the bowl portion 2 is supported by the bowl support rib 1c. ing. The lower end part of each bowl support rib 1c comes in contact with the toilet floor. Thereby, the skirt part 1 can be stably placed on the installation floor of the toilet, the skirt part 1 is hardly bent, and the support of the bowl part 2 is also stabilized.

このように、スカート部１の内面に形成したボウル支持リブ１ｃのボウル受け部１ｄでボウル部２の裏面２ｂを支持することにより、図１（ａ）のように、ボウル部２に作用する垂直方向の衝撃荷重Ｖと水平方向の衝撃荷重Ｈとに対する耐衝撃性が向上するとともに、スカート部１によるボウル部２の支持が安定して、接合時の位置ズレが発生しにくくなる。   Thus, by supporting the back surface 2b of the bowl portion 2 with the bowl receiving portion 1d of the bowl support rib 1c formed on the inner surface of the skirt portion 1, the vertical acting on the bowl portion 2 as shown in FIG. The impact resistance against the horizontal impact load V and the horizontal impact load H is improved, and the support of the bowl portion 2 by the skirt portion 1 is stabilized, so that positional displacement during joining is less likely to occur.

また、複数個のボウル支持リブ１ｃを形成することにより、耐衝撃性がより向上するとともに、スカート部１によるボウル部２の支持がより安定するようになる。   Further, by forming the plurality of bowl support ribs 1c, the impact resistance is further improved, and the support of the bowl part 2 by the skirt part 1 becomes more stable.

さらに、ボウル支持リブ１ｃを放射状に形成することにより、少ない個数で耐衝撃性がより向上するとともに、スカート部１によるボウル部２の支持がより安定するようになる。   Furthermore, by forming the bowl support ribs 1c radially, the impact resistance is further improved with a small number, and the support of the bowl part 2 by the skirt part 1 becomes more stable.

さらにまた、ボウル支持リブ１ｃの隣り合う隙間ｓに発泡材を充填すれば、ボウル支持リブ１ｃと発泡材とが相俟ってボウル部２の裏面全体を支持できるので、スカート部１によるボウル部２の支持がより安定するとともに、便器全体を軽量化できるようになる。   Furthermore, if the gap s adjacent to the bowl support rib 1c is filled with a foam material, the bowl support rib 1c and the foam material can be combined to support the entire back surface of the bowl portion 2, so that the bowl portion by the skirt portion 1 can be supported. The support of 2 becomes more stable, and the entire toilet can be reduced in weight.

この発泡材は保温性（若しくは断熱性）を有するので、寒冷地における便器内の残水の凍結を防止することができるとともに、発泡材によってボウル部２の肉厚が実質的に厚くなるので、このような肉厚を厚くする箇所をボウル部２の表面（洗浄面）の後方側に設定すれば、特に男性の尿水等〔図３（ｂ）の矢印ａ参照〕が当たりやすい部分の振動が抑制されて当たり音を減衰できるようになる。   Since this foam has heat insulation (or heat insulation), it can prevent freezing of the residual water in the toilet in a cold region, and the wall thickness of the bowl portion 2 is substantially increased by the foam, If such a thickened portion is set on the rear side of the surface (cleaning surface) of the bowl portion 2, the vibration of the portion that is particularly likely to hit male urine etc. (see arrow a in FIG. 3B). Is suppressed and the hit sound can be attenuated.

なお、ボウル支持リブ１ｃは、スカート部１とは別体の発泡成形体として別に成形して、それをスカート部１に接合しても良く、同時にボウル支持リブ１ｃの隣り合う隙間ｓに発泡材を充填することもできる。   The bowl support rib 1c may be separately molded as a foam molded body separate from the skirt portion 1, and may be joined to the skirt portion 1, and at the same time, the foam support material may be placed in the gap s adjacent to the bowl support rib 1c. Can also be filled.

図３（ａ）は別実施形態のスカート部の平面図、図３（ｂ）は図３（ａ）のIII−III線断面図、図３（ｃ）は図３（ｂ）のIV−IV線断面図であり、図３（ａ）（ｂ）に仮想線で輪郭とハッチングを示したように、ボウル支持リブ１ｃのボウル受け部１ｄに、ボウル部２の裏面２ｂに沿う略半球形状の発泡成形体５を配置している。この発泡成形体５は、ボウル部２の裏面２ｂ側の全面に配置する必要は無く、少なくともボウル部の貯水面（喫水面）Ｌの付近だけ、好ましくは、貯水面（喫水面）Ｌ以下に位置するように配置する。   3A is a plan view of a skirt portion according to another embodiment, FIG. 3B is a cross-sectional view taken along line III-III in FIG. 3A, and FIG. 3C is IV-IV in FIG. 3B. 3 (a) and 3 (b), the outline and hatching are shown in phantom lines in FIGS. 3 (a) and 3 (b), and the bowl receiving portion 1d of the bowl support rib 1c has a substantially hemispherical shape along the back surface 2b of the bowl portion 2. The foam molded body 5 is arranged. The foamed molded body 5 does not need to be disposed on the entire back surface 2b side of the bowl portion 2, and is at least near the water storage surface (draft surface) L of the bowl portion, preferably below the water storage surface (draft surface) L. Arrange to position.

このように、ボウル支持リブ１ｃのボウル受け部１ｄに発泡成形体５を配置することにより、発泡成形体５でボウル部２の裏面全体を支持できるので、スカート部１によるボウル部２の支持がより安定するようになる。   In this way, by disposing the foam molded body 5 on the bowl receiving portion 1d of the bowl support rib 1c, the entire back surface of the bowl portion 2 can be supported by the foam molded body 5, so that the bowl portion 2 is supported by the skirt portion 1. It becomes more stable.

また、発泡成形体５を少なくともボウル部２の貯水面（喫水面）Ｌ以下の位置とすることにより、発泡成形体５は保温性（若しくは断熱性）を有するので、寒冷地における便器内の残水の凍結を防止することができるとともに、発泡成形体５によってボウル部２の肉厚が実質的に厚くなるので、特にボウル部２の表面（洗浄面）の後方側において、尿水等〔図３（ｂ）の矢印ａ参照〕が当たりやすい部分における当たり音を減衰できるようになる。   In addition, by setting the foam molded body 5 to a position at least below the water storage surface (draft surface) L of the bowl portion 2, the foam molded body 5 has heat retention (or heat insulation). The freezing of water can be prevented and the thickness of the bowl portion 2 is substantially increased by the foamed molded body 5, so that urine water or the like [particularly on the rear side of the surface (cleaning surface) of the bowl portion 2 [Fig. 3 (b) arrow a]], it is possible to attenuate the hit sound in the portion where it is easy to hit.
