Description

【０００１】
【発明の属する技術分野】
本発明は、主に一般室内で使用するポータブルトイレの便座取付構造に関するものである。
【０００２】
【従来の技術】
従来のポータブルトイレの便座取付構造は、便座の後部縁の左右に突設された取付部の左右水平方向に設けられた軸孔部に、それぞれ軸部材を挿入して便器本体に回動可能に取り付けられる構造であった。例えば、特許文献１には便器の便座や便蓋等を便器本体に取り付けるヒンジ機構の技術が開示されている。この従来技術（特許文献１）は、二つの軸受部を有する基台を便器本体に取り付け、この基台の二つの軸受部で便座を回動可能に軸止する構造であるが、便座を軸受部に取り付ける際には、便座の後部縁の左右に設けられた軸孔を軸受部に合わせておき、二つの軸部材をそれぞれの軸受部に挿入して行うものである。

【発明が解決しようとする課題】
上記従来の技術では、便座を便器本体に取り付けるには、まず便器本体に基台を嵌め込み、そして便座の後縁部に設けられた二つの軸孔にそれぞれ軸部材を挿入しなければならなかった。よって、便座の取付けのための部品点数が多く、取付け作業が面倒であった。より詳細に言えば、上記従来の技術では、少なくとも基台と二つの軸部材の合計３点の部品が便座取付けのために必要であった。しかも、部品点数が多いため、便座を分解したときに部品を紛失しやすいという問題もあった。
【０００５】
さらに、便座の開閉に際して、騒音や振動防止を主な目的に緩衝動作を行うためのダンパーを回動軸部に設けることがあるが、このようなダンパーを取り付けるとさらに部材点数が増えると共に、取付作業などが煩雑化する問題があった。さらに、軸部の周辺にダンパー部材が露出してポータブルトイレの見栄えが悪くなる問題があった。
【０００６】
本発明は、斯かる実情に鑑み、部品点数の少ないポータブルトイレの便座取付構造を提供することを目的とする。さらに、本発明の目的は、簡単に便座を取り付けることができるポータブルトイレの便座取付構造を提供することにある。また、ダンパー部材を取り付けても、便座の取付作業が簡単に行える取付構造を提供することも本発明の目的である。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、請求項１に記載の発明では、便器本体の上面後部に左右水平方向に向けて配置される回動軸を中心に回動可能に取り付けられた便座部を備えたポータブルトイレであって、前記便座部には、後端部から後方に突出した取付部が予め定められた間隔を開けて左右に二カ所設けられており、前記左右の取付部に対する軸部の少なくとも一つは、便器本体部に配設されるダンパー付き軸部材で軸支され、前記ダンパー付き軸部材の軸部を外部に露出するようにして上部から覆い隠すと共に、前記左右の取付部の間の部分に位置するように、前記便器本体部に対して着脱可能に設けられている樹脂製のカバー部材を備えている、ことを特徴とするポータブルトイレの便座取付構造を提供する。
【０００８】
本発明における便座部は、後端部から後方に突出した取付部が左右に二箇所設けられており、それぞれは予め定められた間隔を開けている。この取付部のそれぞれに軸部を挿入することによって、軸部回りに便座部が回動可能に便器本体に取り付けられる。即ち、回動軸は左右の水平方向の同じ軸位置であり、それぞれの取付部にそれぞれの軸部材が配設される。
【０００９】
そして、これら二箇所の取付部のうち、少なくとも一つの取付部にはダンパー付きの軸部材が挿入される。このダンパー付き軸部材とは、軸部材を介して取り付けられる便座部を回動させて、下げたときや上げたときに、騒音や振動防止を主な目的に緩衝動作を行うための手段を備えたものである。この緩衝手段としてのダンパーを軸部材側に設けることで、本体部にしっかりと固定できると共に、便座側の構造はシンプルになる。
【００１０】
カバー部材は、このダンパー部材を内部に納め、その軸部分のみを外部に露出する構造であり、取付状態で便座部の左右の取付部の間の位置に配設される。即ち、便座部の左右の取付部の間の位置にダンパー付き軸部材が配置され、その上部を覆うようにカバー部材が取り付けられる。言い換えれば、カバー部材は、便座の取付部の間の空間を塞ぐような構造で、取付軸部などの外部への露出を防ぎ、見栄えも向上する。さらに、この左右の取付部の間の空間を有効活用して、ダンパー部材などの構造部を配設している。
【００１１】
なお、軸部は、左右の水平方向の軸方向であるので、左右の取付部の対向する内側面にそれぞれ軸部に対する受け部が設けられる。逆に、カバー部は、前記それぞれの内側面に対向する外側面部を備えている。これにより、カバー部材を取り付けると、便座部の後端部の取付部の間の空間にカバー部材が填り込んだ状態となるので、外見上もスッキリしてゴミなども溜まりにくく、掃除も楽にできる。
【００１２】
そして、少なくとも一つの取付部に挿入されるダンパー付き軸部材は、軸部のみをこのカバー部材の外側面部からから露出するようにして、取付部の内側面部の受け部に取り付ける構造である。
【００１３】
次に、請求項２に記載の発明では、請求項１に記載のポータブルトイレの便座取付構造において、前記左右の取付部のうち、第一の取付部に対する軸部が、前記ダンパー付き軸部材で軸支され、第二の取付部に対する軸部が、前記カバー部材の外壁部から突出するように一体的に設けられた軸部材からなる、ことを特徴とするものである。
【００１４】
この発明では、一方の取付部をダンパー付き軸部材で構成し、他方の取付部を単なる軸部材に軸支させる構造としたものであり、他の軸部材を個別に設けずに、カバー部材に直接設けていることが特徴である。
【００１５】
即ち、本発明の第二の取付部には、単純な軸部材が挿入される軸受け穴部が水平方向に設けられていれば、カバー部材に一体的に設けられた軸部材と係合して回動構造を形成する。カバー部材は、取付部の内側面に対向する外側面（外壁面）を備えているので、その対向する外側面部に軸部材を設けておけばよい。
【００１６】
そして、カバー部材に対して、まず第二の取付部の軸部を係合させた後、第一の取付部に対して、ダンパー付き軸部材をカバー部材の外壁部（側壁部）から露出させるように嵌め込めば、第一の取付部への軸部材の取付けも完了する。
【００１７】
カバー部材には、ダンパー付き軸部材の少なくとも軸部分を露出させるために、部分的な孔や、縁部から連続する長穴などを備えているが、いずれにしても、ダンパー付き軸部材を仮固定できるような構成が望ましい。例えば、軸部露出用の孔部分で簡単に引っかけておけるなどが好ましい。そして、このような状態で、ダンパー付き軸部材をカバー部材と一緒に便器本体へ取り付ければ良い。
【００１８】
そして、カバー部材とダンパー付き軸部材が本体部に取り付けられることによって、便座部の軸部が本体部に固定されるので、便座部が便器本体に回動可能に取り付けられるのである。同時に、ダンパー付き軸部材の作用により、開閉時の動作に緩衝作用が加わって、便座の回動動作時に衝撃や大きな音などが生じない。これにより、室内などで使用しても無駄な騒音などを発生しない利点がある。
【００１９】
このように、前記第二の取付部に挿入される軸部材は、本発明においては、便器本体に対して着脱可能に設けられた樹脂製のカバー部材の外壁部から突出するように一体的に設けられている。これは、カバー部材の樹脂成形時に同時に形成してしまうのが製造工程の簡略化や、部品点数の削減効果があって好ましい。
【００２０】
この構成により、便座部の第一の取付部にダンパー付き軸部材を挿入し、第二の取付部にはカバー部材と一体的に設けられた軸部材を挿入し、このカバー部材をそのまま便器本体に取り付ければ便座は便器本体に回動可能に取り付けられることとなる。つまり、便器本体に便座を取付けるための部品点数は、軸部材が外壁部に突出したカバー部材とダンパー付き軸部材の合計２点で良いこととなる。よって、部品点数が少なく、簡単に便座を便器本体に取り付けることができる。しかも、部品点数が少ないので便座を取り外して便器の清掃などを行う際に、構成部品が紛失する心配もない。
【００２１】
ここで、カバー部材の便器本体への取付構造は本発明においては特に限定されるものではない。例えば、便器本体に穴部を設けておき、カバー部材の下部に突起部を設け、この突起部を便器本体の穴部に挿入して取り付けるよう着脱可能に構成すればよい。
【００２２】
また、本発明においてカバー部材はダンパー付き軸部材の軸部を外部に露出するようにして上部から覆い隠すように構成される。即ち、ダンパー付き軸部材は、便座部の第一の取付部に挿入される部分（軸部）以外の部分がカバー部材で覆い隠されるようになっている。従って、外見上、ダンパー付き軸部材は殆ど見えることがなく、外観にも優れたものとなる。
【００２３】
なお、本発明のカバー部材の形状は、ダンパー付き軸部材の軸部を外部に露出するようにして上部から覆い隠せるようになっていれば何れのものであっても良い。また、本発明のダンパー付き軸部材は、便座部の回動速度を緩やかにするためのものであり、回動動作に緩衝作用を生じさせるものであれば、その構成は特に限定されるものではない。
【００２４】
請求項３に記載の発明では、請求項１又は２に記載のポータブルトイレの便座取付構造において、前記便座部が、ヒーターなどの電気構造を備え、該電気構造のコードを略クランク状に折り曲げた状態で前記カバー部材の内部を取り回して、前記カバー部材の側面部に設けたコード通し切り欠き部を通して取出すようにしたことを特徴とするものである。
【００２５】
便座部がヒーターなどの電気構造を備えて構成されている場合には、便座部に電気を供給するために電気コードが付いているのが一般的であるが、この電気コードを自由な状態でそのままコンセントに差込む構造のものでは、便座部の開閉のたびにコードが折れ曲がったりしてコードが断線等してしまうことがある。
【００２６】
そこで、本発明では電気コードをクランク状に折り曲げてカバー部材の内部で取り回して通過させるようにして、電気コードが折れ曲がり難くなるようにしたのである。より詳細に言えば、本発明は電気コードをカバー部材内に通過させる際に、便座部に取り付けられた電気コードを略クランク形状に折り曲げた状態でカバー部材内に取り込み、カバー部材の側面部に設けたコード通し切り欠き部を通して外部へ取出すように構成されている。
【００２７】
一例としては、例えば図２に示すように、便座部の後端面部で、左右取付部のいずれかの外側部分から電気コードを外部に取り出して、カバー部材の後部において、一方の側面から他方の側面側へ渡るように取り回すことで、電気コードの略クランク形状を構成できる。
【００２８】
他の例としては、電気コードを軸部の内部を貫通させることも考えられる。即ち、軸部を大径にして内部貫通孔を設け、その軸内貫通孔の内部に電気コードを通すことも可能である。便座側では、これに対応する取付部の内部を通して、前記貫通孔付き軸部へと電気コードを導けば、この軸を通過する部分で、電気コードに略クランク状に取り回されることになる。この場合のカバー部材からの取り出し部は、左右の側面部でも良いが、後側の側面部（後面部）でも構わない。
【００２９】
いずれの場合でも、カバー部材は上部から被せる構造であるので、カバー部材の本体部に接する部分に上方へ向かう切り欠き部を設けてコード通し切り欠き部とすれば、長いコードも邪魔にならずにこの切欠部を通して取付けが簡単に行える。
【００３０】
このように構成することによって、カバー部材が電気コードをクランク状に保持するから、電気コードが勝手に折れ曲がったりすることを防止できる。よって、電気コードが断線するようなトラブルを防ぐことができるのである。
【００３１】
本発明の別の態様では、請求項１〜３のいずれかに記載のポータブルトイレの便座取付構造において、本体部に上部が開放された構成の受け部を備えたダンパー取付部を有し、前記ダンパー付き軸部材は、前記ダンパー取付部に上部から嵌め込むことで設置される保持構造部を備えている。
【００３２】
このため、ダンパー付き軸部材は、ダンパー取付部に上部から保持構造部を組み入れる（又は嵌め込む）ことで、本体部に保持されて設置できるので、取付作業が容易になる。さらに、カバー部材と一緒に取り付ける際にも、簡単に取付作業を行える。
【００３３】
例えば、ダンパー軸部材は、軸とは反対側の後部や、取付時の下方となる部分に所定形状の凸部を保持構造部として設け、前記便器本体部には前記凸部に対応する凹部（受け部）からなるダンパー取付部（支持部材）を設けておき、しかも、ダンパー取付部の凹部の上部が開放された構成とすれば、その上部から前記凸部を組み入れればダンパー付き軸部材は簡単に装着できることになる。
【００３４】
この場合には、ダンパー付き軸部材は、その後部（便座部の取付部に挿入される軸部と反対の部分）に凸部を有し、この凸部が便器本体部に立設するダンパー取付部に設けられた凹部に嵌め込まれるようになっているから、ダンパー付き軸部材がガタガタしたり、回動したりすることなく、しっかりと便器本体部に取り付けられるようになる。なお、このような取付構造は、便座部のダンパー部として力を受けても大丈夫な程度の強度で設計されていることは言うまでもない。
【００３５】
つまり、ダンパー付き軸部材の凸部（保持構造部）と、この凸部に対応するダンパー取付部（支持部材）の凹部（受け部）との嵌合によってダンパー付き軸部材がしっかりとダンパー取付部（支持部材）によって本体部に保持され、便座部の回動が安定するのである。しかも、凸部と凹部との嵌合による取付構造とすることにより、便座部の取り付け作業は簡単に行うことが可能である。なお、本発明における凸部と凹部は、嵌合状態がしっかりと維持されるようになっていれば何れの形状であっても構わない。
【００３６】
本発明の別の態様によれば、上記いずれかに記載のポータブルトイレの便座取付構造において、前記カバー部材は下方に突出した構成の差込部を備え、前記便器本体部には、この差込部を受け入れる差込孔部が設けられ、この差込部は差込穴部に挿入された状態で、差込部や差込穴部の素材の可撓性を利用して取付固定されることを特徴とする。
【００３７】
即ち、カバー部材を取り付ける際には、差込部を差込穴部に挿入して押し込めば、その材料の可撓性を利用して一部変形しながら差し込まれ、最終的には可撓性を利用したロック構造で固定されるものである。そして、取り外す際には、この取付時の可撓性の変形状態の逆方向に力を加えてやることで、ロック状態を開放して、差込穴部から差込部を抜き出すことができるものとなる。
【００３８】
例えば、カバー部材の本体取付時の下端部に、下方に突出した可撓性部材からなる差込部を二箇所に設け、前記便器本体部の上面部には前記差込部に対応する差込穴部を設け、前記差込部を前記差込穴部に嵌め込むことにより、前記カバー部材を前記便器本体部へ取り付けられるように構成する。
【００３９】
この構成では、カバー部材の下端部に下方に突出した差込部を二箇所設けているので、その装着時には、差込部の相対的な距離が離れるか近づく方向に、素材の可撓性を利用して変形するように構成し、最終的な取付状態では、この変形が開放されて嵌り込む様な構成にすればよい。具体的には、差込部にテーパ部を備えて、差し込まれた状態ではこのテーパ部の根元部（テーパの出っ張りがない部分）に嵌合するような構成にすればよい。
【００４０】
これにより、カバー部材の便器本体部への取り付けは、差込部を差込穴部に嵌め込むだけの簡単なものとなる。あるいは、差込部は可撓性部材からなるものであるため、カバー部材を便器本体部へ取り付けるときには、可撓性部材からなる差込部を手で撓ませて便器本体部の差込穴部に嵌め込むだけで簡単にカバー部材を便器本体部に取り付けることができることとなる。また、カバー部材を取り外すときにも、差込部が可撓性部材であるから、嵌め込むときと逆向きに差込部を撓ませるだけで簡単に便器本体部から取り外すことができる。
【００４１】
ここで、本発明における差込部は少なくとも二箇所に設けられていれば十分である。少なくとも二箇所に設けられていれば便器本体にしっかりと取付固定できるからである。勿論、それ以上差込部を設けておいても良い。
【００４２】
次に、本願請求項４記載発明では、便器本体の上面後部に左右水平方向に向けて配置される回動軸を中心に回動可能に取り付けられた便座部を備えたポータブルトイレであって、前記便座部には、その後端部から後方に突出した取付部に対して、軸受け部が左右に二カ所設けられており、前記左右の軸受け部の一つには、便器本体部に配設されるダンパー付き軸部材で軸支され、前記ダンパー付き軸部材の軸部を外部に露出するようにして上部から覆い隠すと共に、前記便器本体部に対して着脱可能に設けられている樹脂製のカバー部材を備えており、前記左右の軸受け部の他の一つには、前記樹脂製のカバー部材の前記軸受け部と対向する壁部から突出するように一体成形された軸部材を備えている、ことを特徴とするポータブルトイレの便座取付構造を提供する。
【００４３】
この発明では、便座部には後方に突出する状態で設けられた取付部が存在し、その取付部には、左右に二カ所の軸受け部を備えている。この軸受け部は、便座部の回動中心となる軸受け部であるから同軸上に構成されていることはいうまでもない。さらに、左右に二カ所の軸受け部が存在すればよいので、取付部を一カ所として、その左右の側面部にそれぞれ軸受け部を設けたものでも、取付部を左右に二カ所設けた上で、それぞれの取付部に軸受け部を設けているものでも良い。
【００４４】
さらに、本発明では、二カ所の軸受け部のうち、一カ所にはダンパー付き軸受け部材を軸支させ、便座の開閉動作に緩衝作用を付加するものとしている。他の軸受け部には、自由か移動可能な軸受け部で構成し、そこに軸部材を設けて回動中心となるようにしている。
【００４５】
ダンパー付き軸受け部材は、本体部に取り付けられるが、その軸部を除いてカバー部材が覆い隠す構成であり、カバー部材から軸受け部のみが突出した構成とすることができるものである。
【００４６】
そして、そのカバー部材には、他方の軸受け部に対する軸部材が一体成形されているので、この一体成形軸部材側を最初にカバー部材の一つの軸受け部に装着し、その後、ダンパー付き軸部材をカバー部材を取り付けた状態のままで装着する。これにより、便座部は二つの軸受け部に、それぞれ軸部材が装着された状態となり、その状態でカバー部材に（回動可能に）保持されている。
【００４７】
そして、カバー部材ごと、便座部と、ダンパー付き軸部材を便器本体に取り付ければ、一度で便器本体部にこれらの部材が装着できるので、組み立て工程が極めて容易である。さらに、部品点数も少なくて、製造コストを抑えることも可能である。
【００４８】
また、別の態様としては、上記請求項４に記載のポータブルトイレの便座取付構造において、前記便座部が、ヒーターなどの電気構造を備え、該電気構造のコードを略クランク状に折り曲げた状態で前記カバー部材の内部を取り回して、前記カバー部材の側面部に設けたコード通し切り欠き部を通して取出すように構成する。
【００４９】
この構成によれば、電気コードをクランク状に折り曲げてカバー部材の内部で取り回して通過させるようにできるから、電気コードが折れ曲がり難くなる。より詳細に言えば、電気コードをカバー部材内に通過させる際に、便座部に取り付けられた電気コードを略クランク形状に折り曲げた状態でカバー部材内に取り込み、カバー部材の側面部に設けたコード通し切り欠き部を通して外部へ取出すようにすれば、電気コードが折れ曲がり難くなるのである。
【００５０】
一例としては、便座部の後端面部で取付部の外側部分から電気コードを外部に取り出して、カバー部材の後部において、一方の側面から他方の側面側へ渡るように取り回すことで、電気コードの略クランク形状を構成できる。
【００５１】
他の例としては、電気コードを軸部の内部を貫通させることも考えられる。即ち、軸部を大径にして内部貫通孔を設け、その軸内貫通孔の内部に電気コードを通すことも可能である。便座側では、これに対応する取付部の内部を通して、前記貫通孔付き軸部へと電気コードを導けば、この軸を通過する部分で、電気コードに略クランク状に取り回されることになる。この場合のカバー部材からの取り出し部は、左右の側面部でも良いが、後側の側面部（後面部）でも構わない。
【００５２】
いずれの場合でも、カバー部材は上部から被せる構造であるので、カバー部材の本体部に接する部分に上方へ向かう切り欠き部を設けてコード通し切り欠き部とすれば、長いコードも邪魔にならずにこの切欠部を通して取付けが簡単に行える。
【００５３】
このように構成することによって、カバー部材が電気コードをクランク状に保持するから、電気コードが勝手に折れ曲がったりすることを防止できる。よって、電気コードが断線するようなトラブルを防ぐことができるのである。
【００５４】
【発明の実施の形態】
以下、本発明の一実施形態に係るポータブルトイレにおける便座の取付構造を図示例と共に説明する。尚、図中、図と同一の符号を付した部分は同一物又は相当物を表わしている。本発明の一実施形態に係る便座の取付構造は、図１に示すように、ポータブルトイレの便座部１の後縁部に設けられた二つの取付部２ａ，２ｂのうち、第一の取付部２ａにダンパー付き軸部材３を挿入し、第二の取付部２ｂには軸部材６を挿入すると共に、カバー部材４を便器本体５の上面後部に取付けて、便座部１を便器本体部５に取り付ける構造のものである。
【００５５】
取付部２ａ，２ｂは、それぞれ所定の間隔を開けて、便座部１の後縁部から後方（図１中の右斜め上方向）に突出するように形成されており、取付部２ａにはダンパー付き軸部材３を挿入するための孔部２０ａが開けられている。また、取付部２ｂには軸部材６を挿入するための孔部２０ｂが開けられている。
【００５６】
ダンパー付き軸部材３は、その後部に断面略矩形の凸部７（保持構造部）が設けられている。また、便器本体部５の上面にはダンパー取付部（支持部材）であるブラケット２２が立設されており、このブラケット２２は上面部と一側側面部とに亘る凹部８が受け部として形成されている。この凹部８は、上部が開放されており、その内部は、ダンパー付き軸部材３の凸部７の外形形状に対応するように形成されていて、この凹部８にダンパー付き軸部材３の凸部７を上方から嵌め込むことによって、ダンパー付き軸部材３は回動することなくしっかりと本体部に固定されるようになっている。なお、凹部８の上面開口部分はダンパー付き軸部材３の凸部の挿入を容易とするために凸部の形状よりやや大きくして、テーパ状の受け部を備えている。
【００５７】
カバー部材４は、樹脂製部材（本実施形態ではプラスチック製）で一体成型された略矩形箱型形状となっており、底部は開放されている。そして、左右側面部の外壁部は、二つの取付部２ａ，２ｂの内壁部と相対するように若干の隙間を持って近接して配置される。一方の外壁部の外側には、先端部がやや細い略円柱形状の軸部材６が外部へ突出するようにカバー部材３と一体的に成形されている。また、他方の側面（軸部材６が設けられている側面部と対向する側面）部には、貫通孔２１が設けられており、ここから、ダンパー付き軸部材３の軸部（取付部２ａの孔部２０ａに挿入する部分）が外部に露出するように取り付けられる。
【００５８】
即ち、ダンパー付き軸部材３の本体部分は、カバー部材４が上部から覆い隠すように配置され、あるいは、カバー部材４の内部にダンパー付き軸部材３の軸部以外の部分が収納されて、ダンパー付き軸部材３の軸部のみがカバー部材４の外部に露出することになる。実際には、ダンパー付き軸部材３の軸部は、便座部１の取付部２ａの孔部２０ａに挿入される。
【００５９】
さらに、カバー部材４の左右側壁部の下端部で対向する位置には、二つの差込部９ａ，９ｂが下方に突出した状態で取り付けられている。この二つの差込部９ａ，９ｂはカバー部材と一体成型されているので可撓性部材で形成されており、手で押さえると撓むようになっている。そして、差込部９ａ，９ｂは、外側に先端から徐々に分厚くなるテーパ状の傾斜面（若しくは、くさび状の傾斜面）を備えており、側壁の下部に連続する根元部が一番分厚くなって、いわゆる略矢尻状に構成されている。
【００６０】
便器本体５の上面後部には、これらの差込部９ａ，９ｂに対応するように開けられた差込穴部１０ａ，１０ｂが配設されており、カバー部材４の差込部９ａ，９ｂをそれぞれ嵌め込めばカバー部材４が便器本体部５に取付固定される。その際に、先端の楔状の傾斜面部に当接して若干変形しながら差し込まれ、差込部９ａ、９ｂの根元まで入った状態でくさび状部が差込孔１０ａ、１０ｂとの接触が開放されて、差込孔内部の入り口脇に、矢尻状部分が係合して固定される。
【００６１】
カバー部材４を取り外すときには、差込部９ａ，９ｂを双方が近づく方向に手で撓ませて（弾性変形させて）、矢尻状部分と差込穴１０ａ，１０ｂとの係合を解いてから引き抜けば、カバー部材４が便器本体部５から簡単に取り外される着脱可能な構成となっている。
【００６２】
カバー部材４は、図２に示すように、本体部に取り付けた状態で、その側壁部は取付部２ａ，２ｂの内壁部にそれぞれ対向して近接し、上面部は便座部１の上面部とほぼ面一になるような大きさに構成されている。このため、便器本体に取り付けた状態では、便座部１と連続する一体構造のように、表面に凹凸のないスムーズな外形が構築できる。
【００６３】
加えて、カバー部材４の後部の両側面（側壁）部の下部には、コード通し切り欠き部１１が設けられており、後述する便座部１の電気コード１２（図２参照）が通過することができるようになっている。
【００６４】
次に、本実施形態に係るポータブルトイレの便座取付構造による便座部の取付方法について図１及び図２と共に説明する。本実施形態に係るポータブルトイレの取付構造によって便座部１を取り付けるには、まず、便座部１の取付部２ｂにカバー部材４と一体となった軸部材６を挿入する。次に、カバー部材４の貫通孔２１と便座部１の取付部２ａの孔部２０ａを位置合わせした状態で、ダンパー付き軸部材３の軸部を、カバー部材４の内側から貫通孔２１に挿し入れた後に、前記孔部２０ａに角度を合わせながら挿入する。この状態で、便座部１はカバー部材４に仮固定されている。
【００６５】
そして、カバー部材４の差込部９ａ，９ｂを手で若干内側に撓ませながら、ダンパー付き軸部材３の凸部７が、ブラケット２２の凹部８にしっかりと嵌め込まれるようにして、便器本体部５の差込穴部１０ａ，１０ｂに上方から嵌め込めば、便座部１の取付けは完了する。即ち、カバー部材の取付作業は、ダンパー付き軸部材の取付作業と一緒に同時に行われる。
【００６６】
このように、本実施形態に係るポータブルトイレの便座取付構造によれば、ダンパー付き軸受け部材とカバー部材とを、便座部１を取り付ける際に一緒に、かつ、極めて簡単に取り付けることが可能となる。しかも、便座部１を取付けるための部品は軸部材６が設けられたカバー部材４とダンパー付き軸部材３の僅かに２点のみである。つまり、２点の部品のみで簡単に便座部１を取り付けることができるのである。
【００６７】
さらに、カバー部材４の外形が、取付部に対向して近接配置される側面部と、便座部の上面部にほぼ面一となるカバー部材の上面部を備えているので、取付状態が便座と一体的にスッキリ納まるものとなっている。
【００６８】

[0004]
[Problems to be solved by the invention]
In the above prior art, in order to attach the toilet seat to the toilet body, the base must first be fitted into the toilet body, and the shaft members must be inserted into two shaft holes provided at the rear edge of the toilet seat. . Therefore, the number of parts for mounting the toilet seat is large, and the mounting operation is troublesome. More specifically, in the above-described conventional technique, at least three parts, a base and two shaft members, are required for mounting the toilet seat. Moreover, since the number of parts is large, there is also a problem that the parts are easily lost when the toilet seat is disassembled.
[0005]
Further, when opening and closing the toilet seat, there is a case where a damper for performing a buffering operation for the main purpose of preventing noise and vibration is provided on the rotating shaft portion, but when such a damper is attached, the number of members further increases, and There was a problem that the work became complicated. Further, there is a problem that the damper member is exposed around the shaft portion and the appearance of the portable toilet is deteriorated.
[0006]
In view of such circumstances, an object of the present invention is to provide a toilet seat mounting structure for a portable toilet with a small number of parts. A further object of the present invention is to provide a toilet seat mounting structure for a portable toilet to which a toilet seat can be easily mounted. It is another object of the present invention to provide a mounting structure that allows a toilet seat to be easily mounted even when a damper member is mounted.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 includes a toilet seat portion rotatably mounted on a rotation shaft disposed in the left and right horizontal direction at a rear upper surface of a toilet body. In the portable toilet, the toilet seat portion is provided with two mounting portions protruding rearward from a rear end at predetermined intervals at two places on the left and right, and at least a shaft portion for the left and right mounting portions. One is pivotally supported by a shaft member with a damper disposed on the toilet body, and covers and hides the shaft portion of the shaft member with the damper from above so as to be exposed to the outside. And a resin cover member provided detachably with respect to the toilet body so as to be located at a portion of the toilet body.
[0008]
The toilet seat according to the present invention is provided with two mounting portions protruding rearward from the rear end on the left and right sides, and each of them has a predetermined interval. By inserting a shaft into each of the mounting portions, the toilet seat is rotatably mounted on the toilet body around the shaft. That is, the rotating shafts are located at the same axial position in the left and right horizontal directions, and the respective shaft members are disposed in the respective mounting portions.
[0009]
Then, a shaft member with a damper is inserted into at least one of the two mounting portions. The shaft member with a damper is provided with a means for rotating the toilet seat attached via the shaft member to perform a buffering operation mainly for preventing noise and vibration when the toilet seat portion is lowered or raised. It is a thing. By providing the damper as the buffer means on the shaft member side, it can be firmly fixed to the main body and the structure on the toilet seat side is simplified.
[0010]
The cover member has a structure in which the damper member is housed inside and only a shaft portion thereof is exposed to the outside, and is disposed at a position between the left and right mounting portions of the toilet seat in the mounted state. That is, the shaft member with the damper is disposed at a position between the left and right mounting portions of the toilet seat, and the cover member is mounted so as to cover the upper part thereof. In other words, the cover member has a structure that closes the space between the mounting portions of the toilet seat, prevents the mounting shaft portion and the like from being exposed to the outside, and improves the appearance. Further, a structural portion such as a damper member is disposed by effectively utilizing the space between the left and right mounting portions.
[0011]
Since the shafts are in the left and right horizontal axial directions, receiving portions for the shafts are respectively provided on opposed inner surfaces of the left and right mounting portions. Conversely, the cover portion has an outer surface facing the respective inner surfaces. As a result, when the cover member is attached, the cover member is inserted into the space between the attachment portions at the rear end of the toilet seat, so that it looks cleaner and it is difficult for dust to collect and it is easy to clean it can.
[0012]
The shaft member with a damper inserted into at least one attachment portion has a structure in which only the shaft portion is exposed from the outer surface portion of the cover member, and is attached to the receiving portion on the inner surface portion of the attachment portion.
[0013]
Next, in the invention according to claim 2, in the toilet seat mounting structure for a portable toilet according to claim 1, of the left and right mounting portions, a shaft portion for the first mounting portion is the shaft member with the damper. It is characterized in that the shaft is rotatably supported, and the shaft with respect to the second mounting portion is formed integrally with the shaft so as to protrude from the outer wall of the cover member.
[0014]
In this invention, one of the mounting portions is constituted by a shaft member with a damper, and the other mounting portion is configured to be supported by a simple shaft member. The feature is that it is provided directly.
[0015]
That is, if the second mounting portion of the present invention is provided with a bearing hole in which a simple shaft member is inserted in the horizontal direction, the second mounting portion engages with the shaft member provided integrally with the cover member. Form a pivot structure. Since the cover member has an outer surface (outer wall surface) facing the inner surface of the mounting portion, a shaft member may be provided on the outer surface facing the outer surface.
[0016]
Then, after the shaft portion of the second mounting portion is first engaged with the cover member, the shaft member with the damper is exposed from the outer wall portion (side wall portion) of the cover member with respect to the first mounting portion. If it fits in this way, the attachment of the shaft member to the first attachment portion is also completed.
[0017]
The cover member is provided with a partial hole, a long hole continuous from the edge, and the like in order to expose at least the shaft portion of the shaft member with a damper. A configuration that can be fixed is desirable. For example, it is preferable that the shaft can be easily hooked at the hole for exposing the shaft. Then, in this state, the shaft member with the damper may be attached to the toilet body together with the cover member.
[0018]
Since the shaft portion of the toilet seat is fixed to the main body by attaching the cover member and the shaft member with a damper to the main body, the toilet seat is rotatably mounted to the toilet main body. At the same time, due to the action of the shaft member with the damper, a shock-absorbing action is added to the operation at the time of opening and closing, so that no impact or loud noise is generated when the toilet seat rotates. Thus, there is an advantage that useless noise is not generated even when used indoors.
[0019]
Thus, in the present invention, the shaft member inserted into the second mounting portion is integrally formed so as to protrude from the outer wall of the resin cover member detachably provided to the toilet body. Is provided. It is preferable that the cover member is formed at the same time as the resin molding, because the manufacturing process is simplified and the number of parts is reduced.
[0020]
With this configuration, a shaft member with a damper is inserted into the first mounting portion of the toilet seat portion, and a shaft member integrally provided with the cover member is inserted into the second mounting portion, and the cover member is directly used as the toilet body. , The toilet seat is rotatably attached to the toilet body. In other words, the number of components for attaching the toilet seat to the toilet body is two in total, that is, the cover member whose shaft member protrudes from the outer wall and the shaft member with a damper. Therefore, the number of parts is small, and the toilet seat can be easily attached to the toilet body. In addition, since the number of parts is small, there is no fear that the components will be lost when the toilet seat is removed and the toilet bowl is cleaned.
[0021]
Here, the mounting structure of the cover member to the toilet body is not particularly limited in the present invention. For example, a hole may be provided in the toilet body, a protrusion may be provided in the lower portion of the cover member, and the protrusion may be detachably configured to be inserted and attached to the hole in the toilet body.
[0022]
Further, in the present invention, the cover member is configured to cover the upper part of the shaft member with the damper so as to expose the shaft part to the outside. That is, the shaft member with the damper is configured such that the portion other than the portion (the shaft portion) inserted into the first mounting portion of the toilet seat is covered and covered by the cover member. Therefore, the shaft member with the damper is hardly visible in appearance, and the appearance is excellent.
[0023]
The shape of the cover member of the present invention may be any shape as long as the shaft portion of the shaft member with the damper is exposed to the outside and can be covered from above. In addition, the shaft member with a damper of the present invention is for slowing down the rotation speed of the toilet seat, and its configuration is not particularly limited as long as it causes a buffering action in the rotation operation. Absent.
[0024]
According to a third aspect of the present invention, in the portable toilet toilet seat mounting structure according to the first or second aspect, the toilet seat portion has an electric structure such as a heater, and a cord of the electric structure is bent into a substantially crank shape. In this state, the inside of the cover member is circulated so as to be taken out through a cord through cutout portion provided on a side surface of the cover member.
[0025]
When the toilet seat is provided with an electric structure such as a heater, an electric cord is generally provided to supply electricity to the toilet seat. In the case of a structure that is directly inserted into an outlet, the cord may be bent and broken, etc. each time the toilet seat is opened and closed.
[0026]
Therefore, in the present invention, the electric cord is bent into a crank shape, routed inside the cover member and passed therethrough, so that the electric cord is hardly bent. More specifically, when passing the electric cord through the cover member, the present invention takes in the cover member in a state where the electric cord attached to the toilet seat portion is bent into a substantially crank shape, and takes in the side portion of the cover member. It is configured to be taken out to the outside through the provided cord notch.
[0027]
As an example, as shown in FIG. 2, at the rear end face of the toilet seat portion, the electric cord is taken out from one of the outer portions of the left and right mounting portions to the outside, and at the rear portion of the cover member, one side is used as the other. By arranging the electric cord so as to extend to the side, a substantially crank shape of the electric cord can be formed.
[0028]
As another example, it is conceivable to pass an electric cord through the inside of the shaft portion. That is, it is also possible to provide an internal through-hole with a large diameter of the shaft portion and to pass an electric cord through the inside of the through-hole. On the toilet seat side, if the electric cord is guided to the shaft portion with the through hole through the inside of the corresponding mounting portion, the electric cord is routed in a substantially crank shape at a portion passing through the shaft. . In this case, the take-out portion from the cover member may be the left and right side portions, or may be the rear side portion (rear surface portion).
[0029]
In any case, since the cover member has a structure that can be covered from above, if a cut-out portion is provided at the portion in contact with the main body portion of the cover member so as to be directed upward, and a cord-passing cut-out portion is provided, a long cord does not interfere. The mounting can be easily performed through the notch.
[0030]
With this configuration, since the cover member holds the electric cord in a crank shape, the electric cord can be prevented from being bent without permission. Therefore, it is possible to prevent trouble such as disconnection of the electric cord.
[0031]
In another aspect of the present invention, the portable toilet toilet seat mounting structure according to any one of claims 1 to 3, further comprising a damper mounting portion provided with a receiving portion having an upper portion opened in a main body portion, The shaft member with a damper includes a holding structure portion that is installed by being fitted into the damper mounting portion from above.
[0032]
For this reason, the shaft member with the damper can be held and installed in the main body by incorporating (or fitting) the holding structure portion into the damper mounting portion from above, thereby facilitating the mounting operation. Further, the mounting work can be easily performed even when mounting together with the cover member.
[0033]
For example, the damper shaft member is provided with a convex portion having a predetermined shape as a holding structure at a rear portion opposite to the shaft or a portion below the shaft at the time of mounting, and a concave portion ( If a damper mounting portion (supporting member) comprising a receiving portion) is provided and the upper portion of the concave portion of the damper mounting portion is opened, the shaft member with the damper can be formed by incorporating the convex portion from the upper portion. It will be easy to install.
[0034]
In this case, the shaft member with the damper has a convex portion at a rear portion thereof (a portion opposite to the shaft portion inserted into the mounting portion of the toilet seat portion), and the convex portion is provided on the toilet body main body. Since the shaft member with the damper is not fitted to the concave portion provided in the portion, the shaft member with the damper can be firmly attached to the toilet body without rattling or rotating. It is needless to say that such a mounting structure is designed to have a strength sufficient to receive a force as a damper portion of the toilet seat portion.
[0035]
That is, the fitting of the protrusion (holding structure) of the shaft member with the damper and the recess (reception portion) of the damper mounting portion (support member) corresponding to this protrusion allows the shaft member with the damper to be securely attached to the damper mounting portion. It is held by the main body by the (supporting member), and the rotation of the toilet seat is stabilized. In addition, since the mounting structure is formed by fitting the convex portion and the concave portion, the operation of mounting the toilet seat can be easily performed. In addition, the convex part and the concave part in the present invention may have any shape as long as the fitted state is firmly maintained.
[0036]
According to another aspect of the present invention, in the portable toilet toilet seat mounting structure according to any one of the above, the cover member includes an insertion portion having a configuration protruding downward, and the insertion portion is inserted into the toilet body portion. An insertion hole for receiving the part is provided, and the insertion part is attached and fixed by utilizing the flexibility of the insertion part and the material of the insertion hole in a state of being inserted into the insertion hole. It is characterized by.
[0037]
That is, when attaching the cover member, if the insertion portion is inserted into the insertion hole portion and pushed in, the insertion is performed while partially deforming by utilizing the flexibility of the material, and finally the flexible material is inserted. It is fixed with a lock structure utilizing the. Then, when detaching, by applying a force in a direction opposite to the flexible deformation state at the time of attachment, the locked state can be released and the insertion part can be pulled out from the insertion hole part. It becomes.
[0038]
For example, at the lower end of the cover member when the main body is attached, two insertion portions made of a flexible member protruding downward are provided at two locations, and the upper surface portion of the toilet body main body has a plug corresponding to the insertion portion. A hole is provided, and the cover member is attached to the toilet body by fitting the insertion portion into the insertion hole.
[0039]
In this configuration, since two lower insertion portions are provided at the lower end of the cover member, the flexibility of the material is reduced in a direction in which the relative distance between the insertion portions is increased or decreased when the insertion portion is mounted. It may be configured so as to be deformed by utilizing, and in a final mounted state, the deformation is released and fitted. Specifically, the insertion portion may be provided with a tapered portion, and when inserted, may be configured to fit into the root portion of the tapered portion (a portion where there is no protrusion of the taper).
[0040]
Thereby, the attachment of the cover member to the toilet body becomes simple, by simply fitting the insertion portion into the insertion hole portion. Alternatively, since the insertion portion is made of a flexible member, when attaching the cover member to the toilet body, the insertion portion made of the flexible member is bent manually to insert the insertion hole portion of the toilet body. The cover member can be easily attached to the toilet body simply by fitting into the toilet body. Also, when removing the cover member, since the insertion portion is a flexible member, it can be easily removed from the toilet body simply by bending the insertion portion in the opposite direction to the insertion.
[0041]
Here, it is sufficient that the insertion portion in the present invention is provided in at least two places. This is because if it is provided at at least two places, it can be securely attached and fixed to the toilet body. Of course, more insertion portions may be provided.
[0042]
Next, in the invention described in claim 4 of the present application, a portable toilet provided with a toilet seat portion rotatably mounted on a rotating shaft disposed in the left and right horizontal direction at a rear portion of the upper surface of the toilet body, In the toilet seat portion, bearing portions are provided at two places on the left and right with respect to the mounting portion projecting rearward from the rear end portion, and one of the left and right bearing portions is provided on the toilet body portion. A resin cover which is supported by a shaft member with a damper, and which covers and hides the shaft portion of the shaft member with the damper from the top so as to be exposed to the outside, and which is detachably provided to the toilet body. The other one of the left and right bearing portions includes a shaft member integrally formed so as to protrude from a wall portion of the resin cover member facing the bearing portion, A portable toilet characterized by that To provide a seat mounting structure.
[0043]
In the present invention, the toilet seat portion has the mounting portion provided so as to protrude rearward, and the mounting portion has two bearing portions on the left and right. Needless to say, this bearing is coaxially configured because it is a bearing that becomes the center of rotation of the toilet seat. Furthermore, since it is sufficient that there are two bearing parts on the left and right, even if the mounting part is one place and the bearing parts are provided on the left and right side parts, the mounting part is provided on two places on the left and right, A bearing portion may be provided in each mounting portion.
[0044]
Further, in the present invention, a bearing member with a damper is pivotally supported at one of the two bearing portions to add a cushioning effect to the opening / closing operation of the toilet seat. The other bearing portion is constituted by a free or movable bearing portion, and a shaft member is provided thereon so as to be the center of rotation.
[0045]
The bearing member with a damper is attached to the main body, but is covered by a cover member except for the shaft portion, so that only the bearing portion protrudes from the cover member.
[0046]
Then, since the shaft member for the other bearing portion is integrally formed on the cover member, the integrally formed shaft member side is first mounted on one bearing portion of the cover member, and then the shaft member with a damper is mounted. Attach with the cover member attached. As a result, the toilet seat portion is in a state in which the shaft member is mounted on each of the two bearing portions, and is held (rotatably) by the cover member in this state.
[0047]
If the cover member, the toilet seat, and the shaft member with the damper are attached to the toilet main body, these members can be mounted on the toilet main body at one time, so that the assembling process is extremely easy. Furthermore, the number of parts is small, and the manufacturing cost can be reduced.
[0048]
Further, as another aspect, in the toilet seat mounting structure for a portable toilet according to the fourth aspect, the toilet seat portion includes an electric structure such as a heater, and a cord of the electric structure is bent in a substantially crank shape. It is configured such that the inside of the cover member is circulated and taken out through a cord through cutout portion provided on a side surface portion of the cover member.
[0049]
According to this configuration, since the electric cord can be bent into a crank shape and routed inside the cover member so as to pass therethrough, the electric cord is hardly bent. More specifically, when the electric cord is passed through the cover member, the electric cord attached to the toilet seat portion is taken into the cover member in a state of being bent into a substantially crank shape, and the cord provided on the side portion of the cover member If the electric cord is taken out through the cutout, the electric cord is hardly bent.
[0050]
As an example, the electric cord is taken out from the outside portion of the mounting portion at the rear end face portion of the toilet seat portion, and routed from one side surface to the other side surface at the rear portion of the cover member, so that the electric cord is Can be formed in a substantially crank shape.
[0051]
As another example, it is conceivable to pass an electric cord through the inside of the shaft portion. That is, it is also possible to provide an internal through-hole with a large diameter of the shaft portion and to pass an electric cord through the inside of the through-hole. On the toilet seat side, if the electric cord is guided to the shaft portion with the through hole through the inside of the corresponding mounting portion, the electric cord is routed in a substantially crank shape at a portion passing through the shaft. . In this case, the take-out portion from the cover member may be the left and right side portions, or may be the rear side portion (rear surface portion).
[0052]
In any case, since the cover member has a structure that can be covered from above, if a cut-out portion is provided at the portion in contact with the main body portion of the cover member so as to be directed upward, and a cord-passing cut-out portion is provided, a long cord does not interfere. The mounting can be easily performed through the notch.
[0053]
With this configuration, since the cover member holds the electric cord in a crank shape, the electric cord can be prevented from being bent without permission. Therefore, it is possible to prevent trouble such as disconnection of the electric cord.
[0054]

Then, the arrowhead-shaped portion is engaged and fixed to the entrance side inside the insertion hole.
[0061]
When removing the cover member 4, the insertion portions 9a and 9b are manually bent (elastically deformed) in a direction in which both approaches, and the engagement between the arrowhead-shaped portions and the insertion holes 10a and 10b is released, and then the pulling is performed. When the cover member 4 comes off, the cover member 4 has a detachable structure that can be easily removed from the toilet body 5.
[0062]
As shown in FIG. 2, when the cover member 4 is attached to the main body, the side walls thereof are opposed to and close to the inner walls of the attachment portions 2a and 2b, respectively, and the upper surface thereof is in contact with the upper surface of the toilet seat 1. It is configured to be almost flush. For this reason, when it is attached to the toilet body, it is possible to construct a smooth external shape with no irregularities on the surface, such as an integrated structure that is continuous with the toilet seat 1.
[0063]
In addition, a cord passage notch 11 is provided below both sides (side walls) of the rear part of the cover member 4 so that an electric cord 12 (see FIG. 2) of the toilet seat 1 described later passes therethrough. Can be done.
[0064]
Next, a method of mounting a toilet seat portion by the portable toilet toilet seat mounting structure according to the present embodiment will be described with reference to FIGS. In order to mount the toilet seat 1 by the portable toilet mounting structure according to the present embodiment, first, the shaft member 6 integrated with the cover member 4 is inserted into the mounting portion 2b of the toilet seat 1. Next, with the through hole 21 of the cover member 4 and the hole portion 20a of the attachment portion 2a of the toilet seat portion 1 aligned with each other, the shaft portion of the shaft member 3 with the damper is inserted into the through hole 21 from the inside of the cover member 4. After the insertion, it is inserted into the hole 20a while adjusting the angle. In this state, the toilet seat 1 is temporarily fixed to the cover member 4.
[0065]
Then, while the insertion portions 9a and 9b of the cover member 4 are slightly bent inward by hand, the projections 7 of the shaft member 3 with the damper are firmly fitted into the recesses 8 of the bracket 22, and the toilet body portion The fitting of the toilet seat portion 1 is completed when the fitting portion 5 is fitted into the insertion holes 10a and 10b from above. That is, the mounting operation of the cover member is performed simultaneously with the mounting operation of the shaft member with the damper.
[0066]
As described above, according to the toilet seat mounting structure for a portable toilet according to the present embodiment, the bearing member with the damper and the cover member can be mounted together with the toilet seat portion 1 and extremely easily. . In addition, there are only two parts for attaching the toilet seat 1: the cover member 4 provided with the shaft member 6 and the damper-mounted shaft member 3. In other words, the toilet seat 1 can be easily attached using only two parts.
[0067]
Furthermore, since the outer shape of the cover member 4 is provided with a side surface portion disposed close to and opposed to the mounting portion, and an upper surface portion of the cover member which is substantially flush with an upper surface portion of the toilet seat portion, the mounting state is the same as the toilet seat It fits neatly into one.
[0068]
And the cover member also serves as the shaft member of the mounting part, and since the member with the damper is housed inside and covered and hidden from the outside, the structural parts such as the damper can be stored neatly in a state that is not noticeable in appearance. Can be done.
[0069]
To remove the toilet seat 1, the insertion portions 9 a and 9 b of the cover member 4 are connected to each other from the back side of the main body (generally, from the toilet tub (not shown) side with the toilet seat 1 opened). The cover member 4 may be pulled upward in a state where the cover member 4 is pressed and bent by hand so as to approach. Even when the toilet seat 1 is removed, there are only two parts to be disassembled: the cover member 4 and the shaft member 3 with a damper, so that there is no risk of loss.
[0070]
Further, when the toilet seat portion 1 is of a type provided with a cord having an electric structure such as a heater, as shown in FIG. If the toilet seat cover 1 is rotated, the cord 12 does not bend if the cord 12 is passed around and taken out from the cord notch portion 11. Therefore, trouble such as disconnection of the cord is solved.
[0071]
FIG. 3 shows a toilet seat mounting structure for a portable toilet according to another embodiment. In this embodiment, the toilet seat portion 101 includes one attachment portion 102 projecting rearward (upper side in FIG. 3) from a rear end portion (upper end portion in FIG. 3). Bearing portions (holes 220a and 220b) are provided on both sides of the mounting portion 102. The cover member 104 is formed integrally with the shaft member 106. The shaft member 106 is inserted into the hole 220b, and the shaft member 103 with the damper having the shaft inserted into the hole 220a is partially exposed. The toilet seat 101 is configured to be rotatable about the shaft member 106 and the shaft member 103 with a damper as a shaft when the toilet seat 101 is attached to the toilet body so as to be covered from above. Even in this embodiment, the toilet seat 101 can be easily attached to the toilet body, and the same operation and effect as described above can be obtained.
[0072]
It should be noted that the toilet seat mounting structure of the portable toilet of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention. For example, in this embodiment, as the shaft member with the damper, the one in which the damper and the shaft portion are configured as an integral part is illustrated, but the damper portion is disposed inside the cover member, and the shaft structure that is continuous therefrom. As long as the action of the damper is transmitted to the portion, it is included in the scope of the present invention, and is not limited to the case where it is integrated.
[0073]
【The invention's effect】
As described above, according to the portable toilet seat mounting structure of the present invention, an excellent effect that the seat can be easily mounted with a small number of parts can be obtained. In addition, even in a toilet seat to which an electric cord is attached, disconnection of the electric cord can be prevented, and the toilet can be used for a long time.
