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、ボウル部の肉厚が薄いと、尿水等が当たりやすい部分が振動することで、当たり音が大きくなり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 when the bowl portion is thin, a portion that is easily hit by urine water vibrates and the hitting sound tends to increase.

本発明は、前記問題を解消するためになされたもので、尿水等が当たりやすい部分の振動を抑制して当たり音を減衰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 an object of the present invention is to provide a toilet devised so as to attenuate the hit sound by suppressing the vibration of a portion that is easily hit by urine water or the like. .

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、前記ボウル部の上端部は、リム部の内辺部の底部に接合する一方、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、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一体形成して、この各ボウル支持リブとボウル部の裏面との間に制振材を配置して、ボウル支持リブで制振材を介してボウル部の裏面を支持するとともに、各ボウル支持リブの下端部は、便器の設置フロアに接するようにしたことを特徴とする便器を提供するものである。 The problem to solve, the present invention includes a skirt portion, and a bowl portion which is disposed inside of the skirt, a three segmented toilet bowl and rim portion joined to the upper portion of the skirt, the The upper end portion of the bowl portion is joined to the bottom portion of the inner side portion of the rim portion, and a bowl support rib that protrudes along the back surface of the bowl portion is formed on the inner surface of the skirt portion in a plan view of the skirt portion. A plurality of pieces are integrally formed so as to radiate from the center of the portion, and a vibration damping material is disposed between each bowl support rib and the back surface of the bowl portion, and the bowl is supported by the bowl support rib via the vibration damping material. In addition to supporting the back surface of each section, the lower end portion of each bowl support rib is in contact with the installation floor of the toilet bowl.

本発明によれば、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、このボウル支持リブとボウル部の裏面との間に制振材を配置して、ボウル支持リブで制振材を介してボウル部の裏面を支持するようにしたから、ボウル部の裏面の制振材の箇所が多重（多層）構造となって肉厚が厚くなるので、制振材の箇所をボウル部の表面（洗浄面）の後方側に設定すれば、尿水等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。
また、ボウル支持リブで制振材を介してボウル部の裏面を支持できるので、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より安定して、接合時の位置ズレが発生しにくくなる。
さらに、各ボウル支持リブの下端部は、便器の設置フロアに接するようになるから、スカート部を便器の設置フロアに安定して置くことができ、スカート部が撓みにくくなるとともに、ボウル部の支持も安定するようになる。 According to the present invention, on the inner surface of the skirt portion, a bowl support rib that protrudes along the back surface of the bowl portion is formed, and a damping material is disposed between the bowl support rib and the back surface of the bowl portion, Since the back surface of the bowl part is supported by the bowl support rib via the vibration damping material, the vibration damping material on the back surface of the bowl part has a multiple (multilayer) structure and the wall thickness is increased. If the location of the material is set on the rear side of the surface (cleaning surface) of the bowl portion, the vibration of the portion that is easily hit by urine water or the like is suppressed and the hit sound can be attenuated.
In addition, since the back surface of the bowl part can be supported via the damping material by the bowl support rib, the impact resistance against the vertical impact load and the horizontal impact load acting on the bowl part is improved, and the skirt part The support of the bowl portion is more stable, and the positional deviation at the time of joining is less likely to occur.
Furthermore, since the lower end of each bowl support rib comes into contact with the toilet floor, the skirt can be stably placed on the toilet floor, making the skirt difficult to bend and supporting the bowl. Will also become 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 line I-I in FIG. 2A, and FIG. 2C is a cross-sectional view taken along 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. The lower end of each bowl support rib 1c comes into 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.

図３（ａ）は制振材８を表示した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、ボウル部２の裏面側の少なくとも一部に制振材８を配置して、制振材８を介してボウル支持リブ１ｃでボウル部２の裏面２ｂを支持するようにしている。この制振材８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 the skirt portion displaying the damping material 8, FIG. 3B is a cross-sectional view taken along the line III-III in FIG. 3A, and FIG. 3C is the view in FIG. It is an IV-IV line cross-sectional view, and as shown in FIGS. 3 (a) and 3 (b), the contour and hatching are shown by imaginary lines, the damping material 8 is disposed on at least a part of the back surface side of the bowl portion 2, The back surface 2b of the bowl portion 2 is supported by the bowl support rib 1c through the vibration damping material 8. The damping material 8 does not need to be disposed on the entire surface on the 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、ボウル部２の裏面２ｂ側の少なくとも一部に制振材（例えばマグネシウム材）８を配置することにより、ボウル部２の裏面２ｂの制振材の箇所が多重（多層）構造となって肉厚が厚くなるので、制振材８の箇所をボウル部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。   In this way, by arranging the damping material (for example, magnesium material) 8 on at least a part of the back surface 2b side of the bowl portion 2, the portion of the damping material on the back surface 2b of the bowl portion 2 has a multiple (multilayer) structure. Therefore, if the location of the damping material 8 is set on the rear side of the surface (cleaning surface) of the bowl portion 2, particularly male urine (see arrow a in FIG. 3B) The vibration of the portion that is easy to hit is suppressed and the hit sound can be attenuated.

また、スカート部１の内面のボウル支持リブ１ｃで制振材８を介してボウル部２の裏面２ｂを支持できるので、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の支持がより安定して、接合時の位置ズレが発生しにくくなる。   Further, since the back surface 2b of the bowl portion 2 can be supported by the bowl support rib 1c on the inner surface of the skirt portion 1 via the vibration damping material 8, the vertical impact acting on the bowl portion 2 as shown in FIG. The impact resistance against the load V and the impact load H in the horizontal direction is improved, and the support of the bowl part 2 by the skirt part 1 is more stable, and misalignment during joining is less likely to occur.

さらに、スカート部１の内面のボウル支持リブ１ｃに制振材８を配置することにより、制振材８でボウル部２の裏面全体を支持できるので、ボウル支持リブ１ｃ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 disposing the damping material 8 on the bowl support rib 1c on the inner surface of the skirt portion 1, the entire back surface of the bowl portion 2 can be supported by the damping material 8, so that the bowl portion 2 is supported by the bowl supporting rib 1c. It becomes more stable.

さらに、制振材８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、制振材８が保温性（若しくは断熱性）を有するタイプであれば、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。   Furthermore, if the damping material 8 is a type having a heat retaining property (or heat insulating property) by placing the damping material 8 at least at a position equal to or less than the water storage surface (draft surface) L of the bowl portion 2, a toilet in a cold region is used. It is possible to prevent freezing of the remaining water inside.

なお、ボウル部２の裏面側の少なくとも一部に制振材８を配置すれば良いことから、スカート部１の内面のボウル支持リブ１ｃは必ずしも必要では無く、ボウル支持リブ１ｃが無いタイプ等でも本発明が適用できることは言うまでもない。   In addition, since the damping material 8 should just be arrange | positioned to at least one part of the back surface side of the bowl part 2, the bowl support rib 1c of the inner surface of the skirt part 1 is not necessarily required, and the type without the bowl support rib 1c, etc. Needless to say, the present invention is applicable.

制振材８は、合成樹脂製のボウル部２にインサートモールドすることが好ましい。このようにすれば、貼り付けの手間を省くことができる。   The damping material 8 is preferably insert-molded into the synthetic resin bowl 2. In this way, it is possible to save the labor of pasting.

制振材８を例えばマグネシウム材（金属材）とすることにより、耐衝撃性がより向上するようになる。   When the damping material 8 is made of, for example, a magnesium material (metal material), the impact resistance is further improved.

また、マグネシウム制振材８をチクソーモールドにより成形することにより、ボウル部２の裏面２ｂに隙間無く密着するような３次元形状で成形できるようになるので、より制振性が向上するようになる。   Moreover, since the magnesium damping material 8 is molded by a thixo mold, it can be molded in a three-dimensional shape so as to be in close contact with the back surface 2b of the bowl portion 2 so that the damping performance is further improved. Become.

前記実施形態において、便器は、スカート部１とボウル部２とリム部３とに少なくとも３分割された合成樹脂製の成形品であり、これらを溶着により接合して一体化した構造である。成形方法としては、射出成形、圧縮成形、真空成形等がある。成形材料としては、比較的強度があるアクリル系樹脂、補強材入りＡＢＳやＰＢＴ等を使用することができる。なお、ボウル部２は、陶器製や金属製であって可能である。   In the embodiment, the toilet bowl is a synthetic resin molded product divided into at least three parts, a skirt part 1, a bowl part 2, and a rim part 3, and these are joined and integrated by welding. Examples of the molding method include injection molding, compression molding, and vacuum molding. As the molding material, relatively strong acrylic resin, ABS or PBT with a reinforcing material, or the like can be used. The bowl portion 2 can be made of earthenware or metal.
