Description

【０００１】
【発明の属する技術分野】
本発明は仮設トイレに関する。
【０００２】
【従来の技術】
例えば災害が発生した時の非難場所やイベント会場、あるいは工事現場などといった不特定多数の人が集まる場所では排泄物を衛生的に処理するために仮設トイレが必要である。このように用いられる仮設トイレは例えば特開平５−２４５０６２号公報に開示されている。ここでの仮設トイレはマンホール口上に設置される敷板を有し、敷板には穴が開けられており、この穴を通して排泄物がマンホール内に落下せしめられる。また敷板の穴の周りであって敷板の底壁面にはリング状の突起が設けられる。この突起は敷板がマンホール口上に設置された時にその外周面がマンホール内周面に接するような大きさとされている。このため敷板がマンホール口上に設置された時に突起はマンホール口の内周面に係合し、敷板をマンホール口に対して位置決めする。
【０００３】
【発明が解決しようとする課題】
ところでマンホール口の大きさは個々に異なる。このため上記仮設トイレを予定していた径より大きな径のマンホール口に設置しようとした場合、敷板の底壁面の突起はマンホール口の内周面に係合せず、したがって敷板はマンホール口に対して位置決めされない。一方、上記仮設トイレを予定していた径より小さな径のマンホール口に設置しようとした場合には敷板の底壁面の突起がマンホール口内に収容されず、したがって敷板はマンホール口に対して位置決めされない。
【０００４】
そこで本発明の目的は異なる大きさのマンホール口に適合可能な仮設トイレを提供することにある。
【０００５】
【課題を解決するための手段】
上記課題を解決するために、１番目の発明では、下水道のマンホール口上に設置される敷板を具備し、該敷板にマンホール口に開口する開口を形成した仮設トイレにおいて、敷板の底壁面から突出する第一の突出部分を前記開口の周囲領域の敷板の底壁面に有すると共に該第一の突出部分が設けられた敷板の底壁面の領域の外側の領域に第二の突出部分を有し、第一の突出部分が第二の突出部分よりも大きく敷板の底壁面から突出し、第二の突出部分の外周面は敷板を第二の径のマンホール口に設置した時に該第二の径のマンホール口の内周面に当接して敷板をマンホール口に対して位置決めし、第一の突出部分の外周面は敷板を第一の径のマンホール口に設置した時に該第一の径のマンホール口の内周面に当接して位置決めすると共に第二の突出部分が敷板の荷重を支持する。
上記課題を解決するために、２番目の発明では、下水道のマンホール口上に設置される敷板を具備し、該敷板にマンホール口に開口する開口を形成した仮設トイレにおいて、敷板の底壁面から突出する第一の突出部分を前記開口の周囲領域の敷板の底壁面に有すると共に該第一の突出部分が設けられた敷板の底壁面の領域の外側の領域に第二の突出部分を有し、第二の突出部分は該第二の突出部分が敷板の底壁面から突出する突出量を零とできるように構成され、第二の突出部分の外周面は敷板を第二の径のマンホール口に設置した時に該第二の径のマンホール口の内周面に当接して敷板をマンホール口に対して位置決めし、第一の突出部分の外周面は敷板を第二の径とは異なる第一の径のマンホール口に設置した時に該第一の径のマンホール口の内周面に当接して敷板をマンホール口に対して位置決めすると共に第二の突出部分はその突出量を零とされている。
３番目の発明では、２番目の発明において、前記第二の突出部分は敷板に枢動可能に取り付けられた支持棒に支持されており、該支持棒を枢動することにより第二の突出部分が敷板内に収容され、第二の突出部分の突出量が零とされる。
上記課題を解決するために、４番目の発明では、下水道のマンホール口上に設置される敷板を具備し、該敷板にマンホール口に開口する開口を形成した仮設トイレにおいて、敷板の底壁面から突出する位置決め突起を前記開口の周囲領域の敷板の底壁面に設け、該位置決め突起は敷板を第一の径のマンホール口に設置すべき時には該第一の径のマンホール口の内周面に当接する第一の外周面を提供し、敷板を第一の径とは異なる第二の径のマンホール口に設置すべき時には該第二の径のマンホール口の内周面に当接する第二の外周面を提供し、マンホール口の径に応じて前記位置決め突起と敷板の開口との間の距離を調節できるように前記位置決め突起を構成した。
上記課題を解決するために、５番目の発明では、下水道のマンホール口上に設置される敷板を具備し、該敷板にマンホール口に開口する開口を形成した仮設トイレにおいて、前記開口の周囲領域に敷板から突出する第一の突出部分を有すると共に該第一の突出部分が設けられた領域よりも前記開口に対して外側の領域に敷板から突出する第二の突出部分を有し、敷板が第二の径のマンホール口に設置される時には第二の突出部分の外周面が第二の径のマンホール口の内周面に当接して敷板をマンホール口に対して位置決めし、敷板が第二の径とは異なる第一の径のマンホール口に設置される時には第一の突出部分の外周面が第一の径のマンホール口の内周面に当接して敷板をマンホール口に対して位置決めすると共に敷板から下方への第二の突出部分の突出量が零とされている。
上記課題を解決するために、６番目の発明では、下水道のマンホール口上に設置される敷板を具備し、該敷板にマンホール口に開口する開口を形成した仮設トイレにおいて、前記開口の周囲領域に敷板から突出する位置決め突起が設けられ、敷板が第一の径のマンホール口に設置される時には前記位置決め突起が該第一の径のマンホール口の内周面に当接する第一の外周面を提供し且つ敷板が第一の径とは異なる第二の径のマンホール口に設置される時には前記位置決め突起が該第二の径のマンホール口の内周面に当接する第二の外周面を提供するように前記位置決め突起と敷板の開口との間の距離がマンホール口の径に応じて調節されるように前記位置決め突起が構成されている。
【０００９】
【発明の実施の形態】
以下、図面に示した実施例を参照して本発明を詳細に説明する。図１を参照すると本発明に係わる仮設トイレ１が示されている。仮設トイレ１は敷板２と、この敷板２上に設置される覆い部分３とを具備する。覆い部分３は四つの側壁３ａと、これら側壁３ａの一つに取り付けられるドア３ｂと、側壁３ａ上に設置される屋根３ｃとを具備する。本発明の敷板２は後述するように蓋を取られたマンホール口上に設置される。また敷板２は軽量かつ堅牢な材料である金属または樹脂により作製される。
【００１０】
図２および図３を参照すると敷板２にはその略中央領域に開口４が形成される。開口４は略楕円形または略長円形である。マンホール口上に設置された本発明の仮設トイレ１の利用者はこの開口４を通して排泄物をマンホール内に落下させることができる。
また開口４の周囲領域であって敷板２の底壁面には敷板２から突出する位置決め突起が設けられる。位置決め突起は二組の突出部分、すなわち四つの第一の突出部分５と四つの第二の突出部分６とを有する。図２に示したように第一の突出部分５はそれぞれ円Ｃ１上に開口４を包囲するように等角度間隔を開けて設けられる。また第二の突出部分６はそれぞれ円Ｃ１より径が大きい円Ｃ２上に開口４および第一の突出部分５を包囲するように等角度間隔を開けて設けられる。このように本実施例では開口４の周囲領域であって敷板２の底壁面に第一の突出部分５が配置され、この第一の突出部分５が設けられた領域の外側の周囲領域であって敷板２の底壁面に第二の突出部分６が設けられる。なお本実施例では円Ｃ１と円Ｃ２とは同心円をなしているが必ずしも同心円をなしていなくてもよい。
【００１１】
また図３に示したように第一の突出部分５が敷板２から突出する量は第二の突出部分６が敷板２から突出する量より大きい。すなわち第一の突出部分５は第二の突出部分６よりも大きく敷板２から突出する。このように本実施例では開口４周りに敷板２の底壁面に対して段違いとなった二つの領域が形成される。なお敷板２上であって開口４近傍には把手２ａが取り付けられる。
【００１２】
ところで図３に示したように第二の突出部分６の外周面は比較的大きい口径（例えば６０ｃｍ）のマンホール口７上に敷板２が設置された時にマンホール口７の内周面に当接する。この時、第一の突出部分５はマンホール口７内に完全に収容されている。また敷板２の荷重はその底壁面の一部により地面８に支持される。ここでは敷板２は第二の突出部分６によりマンホール口７に対して位置決めされる。
【００１３】
一方、図４に示したように第一の突出部分５の外周面は比較的小さい口径（例えば４０ｃｍ）のマンホール口９上に敷板２が設置された時にマンホール口９の内周面に当接する。この時、第二の突出部分６は敷板２の荷重を地面８に支持する。ここでは敷板２は第一の突出部分５によりマンホール口９に対して位置決めされる。
【００１４】
このように本発明によれば口径が異なるマンホール口に対して敷板を位置決めすることができる。
なお第二の突出部分の底面積は第一の突出部分の底面積より広い。これによれば第二の突出部分により敷板の荷重が地面に支持される場合における敷板の安定性が高められる。
【００１５】
次に第二実施例を説明する。図５を参照すると第二実施例の位置決め突起は二組の突出部分、すなわち三つの第一の突出部分１０と、三つの第二の突出部分１１とを有する。第一の突出部分１０は円Ｃ１に沿って設けられる。また第一の突出部分１０は開口４の中心に関して等角度間隔を開けて、すなわち１２０°の角度をもって配置される。さらに第二の突出部分１１は円Ｃ１より径が大きい円Ｃ２に沿って第一の突出部分１０の外側の領域に設けられる。これら第二の突出部分１１も開口４の中心に関して等角度間隔を開けて、すなわち１２０°の角度をもって配置される。
【００１６】
第一実施例と同様に第一の突出部分１０が敷板２から突出する量は第二の突出部分１１が敷板２から突出する量より大きい。
第二実施例の敷板２がマンホール口上に設置された時の各突出部分の機能は第一実施例での機能と同様である。すなわち第二の突出部分１１の外周面は口径が比較的大きいマンホール口上に敷板２が設置された時にマンホール口の内周面に当接する。この時、第一の突出部分１０はマンホール口内に収容されている。また敷板２の荷重はその底壁面の一部により地面に支持される。ここでは敷板２は第二の突出部分１１によりマンホール口に対して位置決めされる。一方、第一の突出部分１０の外周面は口径が比較的小さいマンホール口上に敷板２が設置された時にマンホール口の内周面に当接する。この時、第二の突出部分１１は敷板２の荷重を地面に支持する。ここでは敷板２は第一の突出部分１０によりマンホール口に対して位置決めされる。
【００１７】
第二実施例によれば突出部分を構成する材料の量が少ないので敷板が軽量化される。また第二実施例の突出部分の数は第一実施例の突起部分の数より少ないが第二の突出部分は開口の中心に関して１２０°の角度間隔に位置する三つの点に設けられているので第二の突出部分により敷板が地面に支持された時における敷板の安定性は十分に確保されている。
【００１８】
次に第三実施例を説明する。図６を参照すると第三実施例の位置決め突起は二組の突出部分、すなわち二つの第一の突出部分１２と、二つの第二の突出部分１３とを有する。第一の突出部分１２は円Ｃ１に沿って設けられる。また第一の突出部分１２は開口４の中心に関して互いに反対側に対称に配置される。さらに第二の突出部分１３は第一の突出部分１２の外側の領域に円Ｃ１より径が大きい円Ｃ２に沿って設けられる。これら第二の突出部分１３も開口４の中心に関して互いに反対側に対称に配置される。これら突出部分が設けられる角度は開口の中心に関して１２０°の角度間隔に位置する三つの点上に突出部分が配置される角度とされる。
【００１９】
また第一実施例と同様に第一の突出部分１２が敷板２から突出する量は第二の突出部分１３が敷板２から突出する量より大きい。
第二実施例の敷板２がマンホール口上に設置された時の各突出部分の機能は第一実施例での機能と同様である。すなわち第二の突出部分１３の外周面は口径が比較的大きいマンホール口上に敷板２が設置された時にマンホール口の内周面に当接する。この時、第一の突出部分１２はマンホール口内に収容されている。また敷板２の荷重はその底壁面の一部により地面に支持される。ここでは敷板２は第二の突出部分１３によりマンホール口に対して位置決めされる。一方、第一の突出部分１２の外周面は口径が比較的小さいマンホール口上に敷板２が設置された時にマンホール口の内周面に当接する。この時、第二の突出部分１３は敷板２の荷重を地面に支持する。ここでは敷板２は第一の突出部分１２によりマンホール口に対して位置決めされる。
【００２０】
次に第四実施例を説明する。図７を参照すると第四実施例の敷板２の底壁面には開口４の周りに略環状の位置決め突起１４が設けられる。図８を参照すると位置決め突起１４は開口４に近い内側の第一の突出部分１５と、この第一の突出部分１５の外側の第二の突出部分１６とを具備する。ここで第一の突出部分１５が敷板２から突出する量は第一実施例と同様に第二の突出部分１６が敷板２から突出する量より大きい。
【００２１】
第四実施例の敷板２がマンホール口上に設置された時の各突出部分の機能は第一実施例での機能と同様である。すなわち第二の突出部分１６の外周面は口径が比較的大きいマンホール口上に敷板２が設置された時にマンホール口の内周面に当接する。この時、第一の突出部分１５はマンホール口内に収容されている。また敷板２の荷重はその底壁面の一部により地面に支持される。ここでは敷板２は第二の突出部分１６によりマンホール口に対して位置決めされる。一方、第一の突出部分１５の外周面は口径が比較的小さいマンホール口上に敷板２が設置された時にマンホール口の内周面に当接する。この時、第二の突出部分１６は敷板２の荷重を地面に支持する。ここでは敷板２は第一の突出部分１５によりマンホール口に対して位置決めされる。
【００２２】
次に第五実施例を説明する。図９を参照すると第五実施例の位置決め突起は環状またはリング状の第一の突出部分１７と、環状またはリング状の第二の突出部分１８とを有する。第二の突出部分１８は第一の突出部分１７の外側の領域に配置される。
また第一実施例と同様に第一の突出部分１７が敷板２から突出する量は第二の突出部分１８が敷板２から突出する量より大きい。
【００２３】
第五実施例の敷板２がマンホール口上に設置された時の各突出部分の機能は第一実施例での機能と同様である。すなわち第二の突出部分１８の外周面は口径が比較的大きいマンホール口上に敷板２が設置された時にマンホール口の内周面に当接する。この時、第一の突出部分１７はマンホール口内に収容されている。また敷板２はその底壁面の一部により地面に支持される。ここでは敷板２の荷重は第二の突出部分１８によりマンホール口に対して位置決めされる。一方、第一の突出部分１７の外周面は口径が比較的小さいマンホール口上に敷板２が設置された時にマンホール口の内周面に当接する。この時、第二の突出部分１８は敷板２の荷重を地面に支持する。ここでは敷板２は第一の突出部分１７によりマンホール口に対して位置決めされる。
【００２４】
次に第六実施例を説明する。図１０を参照すると第六実施例の位置決め突起は二組の突出部分、すなわち四つの第一の突出部分１９と、四つの第二の突出部分２０とを有する。第一の突出部分１９は敷板２の底面であって開口４の周りに円Ｃ１に沿って設けられる。また第二の突出部分２０は第一の突出部分１９が設けられた領域の外側の領域には円Ｃ２に沿って設けられる。これら第二の突出部分２０は支持棒２１に取り付けられる。一つの支持棒２１には二つの第二の突出部分２０が取り付けられる。このように第六実施例では図１１を参照すると判るように第二の突出部分２０は支持棒２１を介して敷板２の底壁面から下方へと突出する。各支持棒２１は敷板２の底壁面から下方へと延びる側壁２２に枢動可能に支持される。側壁２２からはハンドル２３が横方向へと突出する。ハンドル２３を用いて支持棒２１を枢動することにより第二の突出部分２０を敷板２の底壁面に対して垂直にしたり、平行にしたりすることができる。
【００２５】
第六実施例では図１１に示したように口径が比較的大きいマンホール口７上に敷板２が設置された時には支持棒２１は第二の突出部分２０が敷板２の底壁面から略垂直下方へと突出するような位置とされている。ここでは第二の突出部分２０の外周面がマンホール口の内周面に当接する。したがって敷板２は第二の突出部分２０によりマンホール口７に対して位置決めされる。この時、第一の突出部分１９はマンホール口７内に収容され、敷板２の荷重は敷板２の側壁２２により支持される。一方、図１２に示したように口径が比較的小さいマンホール口９上に敷板２が設置された時には支持棒２１は第二の突出部分２０が敷板２の底壁面に対して平行となるような位置に枢動せしめられる。ここで第一の突出部分１９の外周面がマンホール口９の内周面に当接する。したがって敷板２は第一の突出部分１９によりマンホール口９に対して位置決めされる。この時、第二の突出部分２０は敷板２内に収容され、敷板２の底壁面からの突出量は零とされる。ここでは敷板２の荷重は敷板２の側壁により支持される。
【００２６】
このように第六実施例ではマンホール口の口径に応じて位置決め突起の突出量を調節することができる。
なお第六実施例においては第一の突出部分１９が敷板２から突出量は第二の突出部分２０が敷板２から突出する量より大きいが、これとは異なり第一の突出部分１９が敷板２から突出量は第二の突出部分２０が敷板２から突出する量より小さくても等しくてもよい。
【００２７】
次に第七実施例を説明する。図１３および図１４を参照すると第七実施例の位置決め突起は四つの突出部分２５を有する。また敷板２には当該敷板２を貫通する四つのスリット２４が形成される。各スリット２４は開口４に隣接した領域から敷板２のコーナーに向かって延びる。各突出部分２５は敷板２の底壁面から略垂直下方へと延びるように各スリット２４に挿入される。突出部分２５はスリット２４に沿って矢印ＡＯおよび矢印ＡＩの方向に摺動可能である。
【００２８】
第七実施例では口径が比較的大きいマンホール口上に敷板２が設置すべき時には突出部分２５がマンホール口内に収容されるように突出部分２５を矢印ＡＩの方向に摺動させ、敷板２をマンホール口上に設置した後に突出部分２５の外周面がマンホール口の内周面に当接するまで突出部分２５を矢印ＡＯの方向へ摺動させる。これにより敷板２がマンホール口に対して位置決めされる。ここでは敷板２の荷重は敷板２の側壁２２により支持される。口径が比較的小さいマンホール口上に敷板２を設置すべき時にも同様に突出部分２５がマンホール口内に収容されるように突出部分２５を矢印ＡＩの方向に摺動させ、敷板２をマンホール口上に設置した後に突出部分２５の外周面がマンホール口の内周面に当接するまで突出部分２５を矢印ＡＯの方向へ摺動させる。これにより敷板２がマンホール口に対して位置決めされる。ここでも敷板２の荷重は敷板２の側壁２２により支持される。
【００２９】
このように第七実施例によればマンホール口の口径に応じて開口に対する位置決め突起の位置、すなわち開口と位置決め突起との間の距離を調節することができる。
なお第一実施例〜第三実施例および第五実施例〜第七実施例では敷板に二組の突出部分、すなわち内側の突出部分と外側の突出部分が設けられているが適合させるべきマンホール口の口径の種類に応じて二組以上の突出部分を設けてもよい。この場合、内側に設けられる組の突出部分ほどその突出量が大きくなるようにする必要がある。
【００３０】
また第一実施例〜第三実施例ならびに第六実施例および第七実施例の各突出部分の形状として扇形を採用し、扇形の円弧面がマンホール口の内周面に当接するようにしてもよい。
【００３１】
【発明の効果】
本発明によれば、口径の異なるマンホール口に敷板を常に安定した状態で設置することができる。
