Description

【０００１】
【発明の属する技術分野】
本発明は、排水管などの流水部材の固定装置に関するものであり、特に、流水部材の現地施工の効率化を図ることが可能な流水部材の固定装置、保持部材の位置決め具および位置決め具の規制部材に関するものである。
【０００２】
【従来の技術】
従来、図１１に示すような排水管（流水部材）Ｐの固定装置１００が知られている。この固定装置１００は、例えば建屋内で発生した各種の汚水を排出するために床下のコンクリート基礎Ｓに敷設される排水管Ｐを固定するためのものであり、細長い矩形状のベース板１０１と、このベース板１０１の両側部から立設された一対のねじ軸１０２と、両側部が各ねじ軸１０２に外嵌されることによって当該ねじ軸１０２に装着される上下一対のバンド体１０３と、各バンド体１０３がねじ軸１０２に外嵌された状態で当該上下一対のバンド体１０３を挟持して締結する各ねじ軸１０２当り２個のナット１０６とからなっている。
【０００３】
前記バンド体１０３は、各側部に設けられた一対の座金部１０４と、これら一対の座金部１０４間に形成された円弧部１０５とから構成されている。かかるバンド体１０３は、各座金部１０４がねじ軸１０２に外嵌された状態で上下の円弧部１０５によって排水管Ｐを挟持し得るようになっている。そして、上下の円弧部１０５によって排水管Ｐが挟持された状態で、各ねじ軸１０２に螺着されている上下のナット１０６で各座金部１０４を締結することにより、排水管Ｐが固定装置１００に固定されることになる。
【０００４】
このような固定装置１００は、ベース板１０１を介してアンカーボルト１０７をコンクリート基礎Ｓ内に螺着し締結することによりコンクリート基礎Ｓ上に敷設されるようになっている。
【０００５】
【発明が解決しようとする課題】
ところで排水管Ｐは、通常、自然流下で汚水を流出させるようになされているため、上流側から下流側に向けて先下がりに傾斜するように敷設されている。したがって、バンド体１０３は、この傾斜に合わせて高さ位置が調節されなければならないが、この高さ位置の調節は、ねじ軸１０２に螺着されているナット１０６を回転操作することによって行われるため昇降速度が非常に遅く、コンクリート基礎Ｓ上に多数敷設された固定装置１００の全てを対象としてかかる作業を行うためには多数の時間を要し、排水管Ｐの敷設工事が極めて非効率なものなるという問題点を有していた。
【０００６】
本発明は、かかる状況に鑑みなされたものであり、流水部材の確実な固定性を確保した上で迅速な高さ位置調節を行うことが可能であり、これによって流水部材の敷設工事の効率化を図ることができる排水管等の流水部材の固定装置、保持部材の位置決め具および位置決め具の規制部材を提供することを目的としている。
【０００７】
【課題を解決するための手段】
請求項１記載の発明は、排水管等の流水部材を保持する保持部材と、この保持部材を所定の高さ位置で支持する支持部材と、設定された保持部材の高さ位置を位置決めする位置決め具とを備えてなる流水部材の固定装置において、前記支持部材は保持部材を支持し得るように構成された少なくとも１本の支柱を備え、前記位置決め具は、支柱との係止で昇降が規制される係止姿勢および支柱との係止が解除されることにより昇降が許容される係止解除姿勢間で姿勢変更可能な係止体と、該係止体の姿勢変更を操作するための操作部とを備え、前記係止体は、操作部のワンタッチ操作で係止姿勢および係止解除姿勢が変更自在に構成されてなることを特徴とする流水部材の固定装置である。
【０００８】
請求項８記載の発明は、排水管等の流水部材を保持する保持部材を、所定の高さ位置で支持部材に連結して位置決めする保持部材の位置決め具であって、支柱との係止で昇降が規制される係止姿勢および支柱との係止が解除されることにより昇降が許容される係止解除姿勢間で姿勢変更可能な係止体と、該係止体の姿勢変更を操作するための操作部とを備え、前記係止体は、操作部のワンタッチ操作で係止姿勢および係止解除姿勢が変更自在に構成されてなることを特徴とする保持部材の位置決め具である。
【０００９】
これらの発明によれば、係止体は、操作部のワンタッチ操作で係止姿勢と係止解除姿勢との間で姿勢変更し得るように構成されているため、従来のようにボルト締め等の面倒な操作を行うことなく保持部材の高さ位置調節および位置決めを容易に行うことができ、流水部材固定装置の現地施工の迅速性を確保する上で有効である。
【００１０】
請求項２記載の発明は、請求項１記載の発明において、前記該支柱には複数の装着孔が狭小隙間を介して連通するように連設されてなる上下方向に延びた長孔が設けられ、前記係止体は、長孔に嵌挿される係止突起を有し、且つ係止姿勢に姿勢設定された状態で係止突起が狭小隙間に阻止されることにより昇降が規制される一方、係止解除姿勢に姿勢設定された状態で係止突起が狭小隙間を通過して昇降し得るように構成されてなることを特徴とするものである。
【００１１】
この発明によれば、係止解除姿勢に姿勢設定された状態の係止体は、係止突起が長孔の狭小隙間を通過し得るようになっているため、操作部を摘持して上下方向に力を加えることにより、当該係止体を支柱に沿って昇降させることができ、これによって保持部材の高さ位置を調節することができる。
【００１２】
保持部材の高さ位置が調節された状態で、操作部を所定の方向に操作して係止体の係止突起が長孔の狭小隙間を通過し得ない係止姿勢に姿勢変更させることにより係止体は係止突起が所定の装着孔に嵌り込んで昇降し得なくなるため、保持部材を設定された高さ位置で支柱に固定することができる。
【００１３】
請求項３記載の発明は、請求項１または２記載の発明において、前記支柱は、保持部材を挟持し得るように対面距離が可変に構成された一対からなることを特徴とするものである。
【００１４】
この発明によれば、保持部材は一対の支柱に挟持されるため、支柱が１本である場合に比較して当該保持部材の支柱による支持状態がさらに安定したものになる。
【００１５】
請求項４記載の発明は、請求項２または３記載の発明において、前記支柱には、上端縁から前記長孔に連通した開口が設けられ、該開口は、少なくとも係止解除姿勢に設定された係止体を通過し得るように口幅寸法が設定されていることを特徴とするものである。
【００１６】
この発明によれば、保持部材に取り付けられた状態の係止体の一部（長孔に嵌め込まれる部分）を開口から嵌め込むことによって係止体を支柱に装着することが可能になり、保持部材の支柱に対する装着操作が容易になる。特に支柱が２本の場合は、一対の支柱間の距離を予め設定した状態で一対の係止体を支柱頂部から各長孔に装着することが可能になり、保持部材の支持部材に対する装着操作の迅速化に貢献する。
【００１７】
請求項５記載の発明は、請求項１乃至４のいずれかに記載の発明において、前記操作部は、前記係止体から前記支柱と反対方向に突設され、前記係止突起の中央部に長孔の狭小隙間を通過し得る軸体が貫通され、該軸体が係止体、長孔および保持部材に抜け止め状態で嵌挿されてなることを特徴とするものである。
【００１８】
この発明によれば、操作部を摘持して係止体を軸体回りに正逆回動させることにより、係止突起が狭小隙間を通過し得る隙間通過姿勢（係止解除姿勢）と、同通過し得ない隙間非通過姿勢（係止姿勢）との間で当該係止体の姿勢変更を行うことができ、係止体の姿勢変更構造が簡単なものになる。
【００１９】
請求項６記載の発明は、請求項５記載の発明において、前記軸体には係止体および保持部材を支柱に密着させる付勢手段が外嵌されてなることを特徴とするものである。
【００２０】
この発明によれば、軸体に外嵌された付勢手段の付勢力によって係止体および保持部材が支柱に押圧されて密着するため、この押圧密着による摩擦力で係止体の設定された姿勢が安定する。
【００２１】
請求項７記載の発明は、請求項６記載の発明において、前記係止体には、支柱に対する対向面に膨出され且つ前記係止突起が膨設されてなる膨出突起が設けられ、該膨出突起は、係止突起が隙間通過姿勢に姿勢設定された状態で狭小隙間を通過し得るように長孔に嵌り込む一方、係止突起を隙間非通過姿勢に姿勢変更させることにより長孔から抜け出るように形状設定されてなることを特徴とするものである。
【００２２】
この発明によれば、係止体は、係止突起が狭小隙間を通過し得る隙間通過姿勢に姿勢設定されることにより膨出突起が長孔に嵌り込み当該長孔に案内されつつ昇降し得るようになるため、この状態で係止体を昇降させて保持部材の高さ位置を調節することができる。
【００２３】
保持部材の高さ位置が設定された状態で操作部を軸体回りに所定の方向に向けて回動操作すれば、膨出突起が付勢手段の付勢力に抗して長孔から抜け出すとともに、膨出突起に設けられた係止突起が隙間非通過姿勢に姿勢設定された状態で装着孔に嵌り込み、これによって係止体は昇降が阻止され、保持部材は高さ位置が固定された状態になる。
【００２４】
そして、保持部材の高さ位置が固定された状態においては、膨出突起の長孔からの抜け出しにより付勢力が増加した付勢手段によって板体の支柱に対する押圧力が増大し、これによって係止体の係止姿勢が安定した状態になるため、保持部材の設定された高さ位置が変化するような不都合が有効に阻止される。
【００２５】
請求項９記載の発明は、請求項５乃至７のいずれかに記載の流水部材の固定装置に対し、係止体および操作部の少なくとも一部を囲うように装着されることを特徴とする位置決め具の規制部材である。
【００２６】
この発明によれば、装着孔に嵌り込んでいる係止突起がその装着孔から外れる（すなわち、係止体が係止姿勢から係止解除姿勢に強制的に姿勢変更される）程の大きな外力が流水部材や保持部材に加わり、その結果、保持部材の高さ位置のずれが生じるような場合であっても、規制部材が支柱と係止体とを一体化し、係止体の強制的な姿勢変更を規制するため、上記問題の発生が好適に防止される。
【００２７】
請求項１０記載の発明は、請求項９記載の発明において、対向する一対の側部と、該一対の側部を連結する連結部とを備え、一対の側部は、操作部に着脱自在に装着されるとともに、装着状態にて支柱を幅方向で挟み込む形状に設定されてなることを特徴とするものである。
【００２８】
この発明によれば、装着孔に嵌り込んでいる係止突起がその装着孔を幅方向に拡開させてその装着孔から外れる程の大きな外力が流水部材や保持部材に加わり、その結果、保持部材の高さ位置のずれが生じるような場合であっても、規制部材の一対の側部が装着孔の拡開を規制するため、上記の問題の発生が好適に防止される。
【００２９】
【発明の実施の形態】
図１は、本発明に係る流水部材の固定装置１０の一実施形態を示す分解斜視図である。また、図２および図３はその組立て斜視図であり、図２は、位置決め具５０が係止姿勢に姿勢設定されることにより保持部材４０の高さ位置が固定された状態、図３は、位置決め具５０が係止解除姿勢に姿勢設定されることにより保持部材４０の高さ位置が調節され得るようになった状態をそれぞれ示している。
【００３０】
これらの図に示すように、固定装置１０は、コンクリート基礎Ｓ（図２）に固定されるベース部材２０と、このベース部材２０に装着される一対の支柱３０と、これら一対の支柱３０間に介設されて支持される、排水管（流水部材）Ｐを保持するための保持部材４０と、この保持部材４０の設定された高さ位置を固定するための位置決め具５０とを備えた基本構成を有している。
【００３１】
前記ベース部材２０は、本実施形態においては、断面視でＵ字形状を呈した鋼材等の金属材料によって形成されている。かかるベース部材２０は、長尺で矩形状の平板部２１と、この平板部２１の両側部から上方に向けて突設され平板部２１の全長に亘って延びる幅方向一対の側板２２とからなり、平板部２１がコンクリート基礎Ｓに接地された状態で当該平板部２１の両端部がアンカーボルト２３によってコンクリート基礎Ｓに固定されることによりベース部材２０がコンクリート基礎Ｓ上に敷設されるようになっている。
【００３２】
前記ベース部材２０の平板部２１には、図１における右方位置に幅方向中央部で長手方向に延びる遊び孔２４が穿設されている。この遊び孔２４は、右側の支柱３０の左右動を案内するためのものである。
【００３３】
前記支柱３０は、外幅寸法がベース部材２０の側板２２間の内寸法より僅かに小さく寸法設定された断面視でＵ字形状を呈する鋼材等の金属材料によって形成されている。かかる支柱３０は、ベース部材２０の平板部２１上に立設される支柱本体３１と、この支柱本体３１の基端部から対向方向に向けて直角に折り曲げられて形成した据付座部３２とからなっている。
【００３４】
支柱本体３１および据付座部３２の幅方向両側部には、支柱３０の内角側に突出した正面視でＬ字形状の側板３３が設けられているとともに、支柱本体３１の側板３３間には垂直板３４が、また据付座部３２の側板３３間には水平板３５がそれぞれ形成されている。このような支柱３０は、一対が各据付座部３２を互いに対向方向に向かわせた状態でベース部材２０の側板２２間に装着されることによって一対の支柱本体３１がベース部材２０上で互いに対向配置で立設されるようになっている。
【００３５】
そして、本実施形態においては、一方の支柱３０（図１〜図３に示す例では左方の支柱３０）は、その据付座部３２がベース部材２０の側板２２間に嵌め込まれた状態で、平板部２１を下面側から貫通したリベット２５が水平板３５の中央部に穿孔された貫通孔に嵌入され、かしめ処理されることによってベース部材２０に固定されている。
【００３６】
これに対し、他方の支柱３０（図１〜図３に示す例では右方の支柱３０）は、その据付座部３２がベース部材２０の側板２２間に嵌め込まれた状態で、平板部２１の遊び孔２４を下面側から貫通したリベット２５が水平板３５の中央部に穿孔された貫通孔に嵌入され、かしめ処理されることによってベース部材２０に装着されている。したがって、右側の支柱３０は、リベット２５が遊び孔２４に案内されつつ当該遊び孔２４の範囲内で左右方向に正逆移動し、排水管Ｐの径寸法に応じて一対の支柱本体３１間の間隔寸法を変化させ得るようになっている。
【００３７】
また、各支柱本体３１の垂直板３４には、上下方向に延びる長孔３７が穿設されている。この長孔３７は、菱形状を呈した菱形孔（装着孔）３８の複数個が一部を重ね合せながら上下方向に連設されることによって形成されている。そして、互いに隣接した菱形孔３８の重なり合っている部分には、幅寸法が菱形孔３８の直径寸法より小さな狭小隙間３８ａが形成されている。かかる長孔３７を介して位置決め具５０が支柱本体３１に装着される。
【００３８】
かかる長孔３７を備えた支柱本体３１の上端面には長孔３７に連通した開口３８ｂが設けられている。この開口３８ｂは、位置決め具５０を長孔３７内へ導くためのものであり、開口幅が長孔３７の狭小隙間３８ａの隙間寸法と同一に寸法設定されている。
【００３９】
前記保持部材４０は、排水管Ｐを挟み込んで保持するためのものであり、帯状の金属材料が円弧状に折り曲げ処理されることによって形成されている。かかる保持部材４０は、半円状の配管受け部４１と、この配管受け部４１の上方位置に形成された幅方向一対の配管抜止め部４２と、配管受け部４１の上端部と、配管抜止め部４２の下端部との間に介設され、かつ、コ字形状を呈して外方に向けて突設された一対のコ字状部４３とを備えて構成されている。
【００４０】
前記配管受け部４１は、内面側が保持するべき排水管Ｐの外径（半径）寸法と等しい曲率半径を有しており、これによって排水管Ｐが配管受け部４１に密着状態で支持されるようになっている。
【００４１】
前記各配管抜止め部４２は、排水管Ｐの外周面に密着し得る曲率半径を備えた円弧状の配管押え部４２ａと、各配管押え部４２ａの上端部から互いに離間する方向に向けて斜め上方に延設された案内片４２ｂとからなっている。案内片４２ｂは、保持部材４０に装着される排水管Ｐを案内するためのものであり、一対の案内片４２ｂに排水管Ｐを支持させた状態で、当該排水管Ｐを下方に向かって押圧することにより、案内片４２ｂが配管押え部４２ａの弾性力に抗して互いに離間し、これによって排水管Ｐは一対の案内片４２ｂ間をすり抜けて保持部材４０内に嵌り込み、配管受け部４１に保持されることになる。
【００４２】
前記各コ字状部４３は、保持部材４０の支柱本体３１への接続用として使用されるものであり、位置決め具５０を構成する後述の軸体５１の頭部５１ｂを嵌め込み得るように互いに離間方向に膨出して形成され、外面が各支柱本体３１の対向面と密着し得る対向面を備えた平板状の軸座４３ａをそれぞれ備えている。各軸座４３ａには、摺接状態で後述の軸体５１を挿通する挿通孔４３ｂがそれぞれ穿設されている。
【００４３】
前記位置決め具５０は、前記長孔３７との関連で保持部材４０の高さ位置を固定するためのものである。以下、図４および図５を基に位置決め具５０について詳細に説明する。図４は、位置決め具５０の構成要素である係止体および操作部を構成する係止金具の第１実施形態を示す展開図である。また、図５は、図４の位置決め具５０の完成斜視図であり、（イ）は、保持部材４０に装着される前の状態、（ロ）は、保持部材４０に装着された状態をそれぞれ示している。
【００４４】
位置決め具５０は、図５に示す軸体５１と、図４に展開状態を示す係止金具５２と、前記軸体５１に外嵌されるスプリングワッシャ５９とを備えて構成されている。前記軸体５１は、図５に示すように、筒状に形成された軸体本体５１ａと、この軸体本体５１ａの一端部に同心で形成された軸体本体５１ａより大径の頭部５１ｂとからなるいわゆる中空リベットが採用されている。軸体本体５１ａは、外径寸法が保持部材４０のコ字状部４３の軸座４３ａに穿設された挿通孔４３ｂより僅かに小さく径設定され、これによって摺接状態で挿通孔４３ｂに嵌挿され得るようになっている。
【００４５】
前記係止金具５２は、図４に示すように、金属製の所定の原料板材にプレス処理を施すことによって打ち抜きで形成され、２本の二点鎖線で示す山折り線に沿って直角に山折りすることによって形成されている。かかる係止金具５２は、中央部に形成された異形平板状の係止体５３と、該係止体５３の左右の端部から外方（図４の紙面の裏面側）に向かって図４の二点鎖線の位置から折り曲げられて形成した左右一対の操作部５７と、各操作部５７から前方（操作部５７の突出方向と反対方向）へ向けて突設された幅方向一対のストッパー５８とからなっている。
【００４６】
前記係止体５３は、幅寸法が支柱本体３１のそれと略同一に設定され、且つ図４における正面視で左上がり右下がりに段違いに形成された異形板体５４と、この異形板体５４の中央部に図４における左上がりの傾斜で延びる前方（図４の紙面の表側）に向かって膨出した直状膨出突起５５と、該直状膨出突起５５の先端面からさらに前方に向かって膨設された幅方向一対の係止突起５６とを備えている。直状膨出突起５５の中央部には、軸体本体５１ａが摺接状態で嵌挿し得る嵌挿孔５５ａが穿設されている。
【００４７】
前記直状膨出突起５５は、係止金具５２の横方向に対して略１０°〜１５°（本実施形態では１３°）で左上がりに傾斜して形成され、係止金具５２が図２に示す係止姿勢（隙間非通過姿勢）に姿勢設定された状態で長孔３７に嵌り込まないように長さ寸法が設定されているとともに、係止金具５２が図３に示すように係止解除姿勢（隙間通過姿勢）に姿勢設定された状態で長孔３７の狭小隙間３８ａに嵌り込み得るように幅寸法が設定されている。また、直状膨出突起５５の異形板体５４からの膨出量は、支柱本体３１の厚み寸法と略同一に設定されている。
【００４８】
前記係止突起５６は、直状膨出突起５５の先端面において嵌挿孔５５ａの孔心に対する点対称位置にそれぞれ蒲鉾状で設けられ、正面視（図４）および側面視でそれぞれ円弧状になるように膨設されている。かかる係止突起５６は、係止金具５２が係止姿勢（図２）に姿勢設定された状態で、図５の（イ）に一点鎖線で示すように、左側の係止突起５６は菱形孔３８の左隅部３８ｃに嵌り込む一方、右側の係止突起５６は１段下の菱形孔３８の右隅部３８ｄに嵌り込むように設置位置が設定されている。係止金具５２が係止姿勢に姿勢設定された状態では、一対の係止突起５６がこれら菱形孔３８の左右の隅部３８ｃ，３８ｄに嵌り込むことにより、位置決め具５０の上下動（昇降）が規制されるようになっている。
【００４９】
上記一対のストッパー５８は、図５の（イ）に示すように、一方のものが右側の操作部５７の上端部から前方に向かって突出しているとともに、他方のものが左方の操作部５７の下端部から前方に向かって突出し、これによって異形板体５４における嵌挿孔５５ａの孔心を基準にした点対称位置に設けられた状態になっている。かかる一対のストッパー５８は、係止金具５２が係止姿勢に姿勢設定された状態で、互いの対向面が、図２に示すように、それぞれ支柱本体３１の側板３３に当接するように寸法設定されている。
【００５０】
このように構成された位置決め具５０は、図５の（イ）に矢印で示すように、保持部材４０のコ字状部４３を支柱本体３１の側板３３間に嵌め込んだ状態で、軸体本体５１ａを保持部材４０のコ字状部４３の挿通孔４３ｂおよび支柱本体３１の長孔３７に挿通し、この状態で係止体５３の嵌挿孔５５ａおよびスプリングワッシャ５９を軸体本体５１ａに外嵌した上で、スプリングワッシャ５９が縮むようにしながら軸体本体５１ａの先端部をかしめることにより、図５の（ロ）に示すように、位置決め具５０が保持部材４０を支持しながら支柱本体３１に装着された状態になる。
【００５１】
そして、位置決め具５０が支柱本体３１に装着された状態では、係止金具５２は、軸体５１回りに正逆回動し得るようになっており、これによって一対の係止突起５６は、所定の菱形孔３８の左隅部３８ｃおよび１段下の菱形孔３８の右隅部３８ｄにそれぞれ嵌り込むとともに、各ストッパー５８が支柱本体３１の側板３３にそれぞれ当止した図２に示す係止姿勢と、この係止姿勢において５７を摘持して軸体５１回りに所定の方向に回動操作することにより直状膨出突起５５が長孔３７に嵌り込んだ図３に示す係止解除姿勢（図６の（イ）参照）との間で姿勢変更し得るようになる。
【００５２】
図６は、第１実施形態の位置決め具５０の作用を説明するため説明図であり、（イ）は、係止金具５２が係止姿勢に姿勢された状態、（ロ）は、係止金具５２が係止解除姿勢に姿勢設定された状態をそれぞれ示している。因みに図６において、（イ）および（ロ）の右に付された添え字の▲１▼は、内側から支柱本体３１に対面した図であり、添え字の▲２▼は、▲１▼の図のＡ−Ａ線断面図であることを示している。
【００５３】
まず、係止金具５２が係止姿勢に姿勢設定された状態では、図６の（イ）−▲１▼に示すように、左右一対のストッパー５８が支柱本体３１の各側板３３に当止した状態で、左側の係止突起５６が所定の菱形孔３８の左隅部３８ｃに嵌り込むとともに右側の係止突起５６が１段下の菱形孔３８の右隅部３８ｄに嵌り込み、しかも異形板体５４は、直状膨出突起５５が長孔３７から抜け出ていることにより、図６の（イ）−▲２▼に示すように、スプリングワッシャ５９の付勢力に抗して（すなわちスプリングワッシャ５９が縮んで）支柱本体３１から離間した状態になっている。
【００５４】
直状膨出突起５５は、スプリングワッシャ５９の付勢力によって支柱本体３１の垂直板３４に押圧されていることにより、その摩擦力で軸体５１回りに回動し難くなっており、これによって係止金具５２は、設定された係止姿勢が安定するようになされている。
【００５５】
この状態で一対の操作部５７を摘んで係止金具５２を軸体本体５１ａ回りに時計方向に回動させると、各係止突起５６は、図６の（ロ）−▲１▼に示すように、菱形孔３８の各隅部３８ｃ，３８ｄから外れるとともに、直状膨出突起５５が、図６の（ロ）−▲２▼に示すように、スプリングワッシャ５９の付勢力によって長孔３７に嵌り込んだ状態になる。この状態では、直状膨出突起５５が狭小隙間３８ａを通過し得るため、操作部５７を摘持して位置決め具５０を昇降させることができる。
【００５６】
そして、位置決め具５０を昇降させて新たな高さ位置が設定された後に、今度は操作部５７を軸体５１回りに反時計方向に回動させると、直状膨出突起５５がスプリングワッシャ５９の付勢力抗して支柱本体３１の垂直板３４に乗り上げていくと同時に、一対の係止突起５６が、図６の（イ）に示すように、新たな高さ位置で菱形孔３８に嵌り込み、これによって保持部材４０、すなわち排水管Ｐの高さ位置が固定される。
【００５７】
図７は、本発明に係る位置決め具５０ａの第２実施形態を示す図であり、（イ）は分解斜視図、（ロ）は組立て斜視図である。この実施形態の位置決め具５０ａは、先の実施形態で採用されていたような直状膨出突起５５が設けられていない点、先の係止突起５６に代えて菱形膨出突起５６０が設けられている点、およびスプリングワッシャ５９が設けられていない点で先の位置決め具５０と相違している。その他の構成は第１実施形態のものと同様である。
【００５８】
すなわち、この実施形態の位置決め具５０ａは、軸体５１と、この軸体５１が嵌挿される係止金具５２とから構成され、係止金具５２は、係止体５３と操作部５７と、ストッパー５８とから構成されている点については、先の実施形態の位置決め具５０と同様であるが、係止体５３が異形板体５４と、この異形板体５４の中心位置に支柱本体３１に向かって膨設された、先の実施形態の係止突起５６に対応する菱形膨出突起５６０とからのみ構成され、直状膨出突起５５は設けられていないばかりか、先の実施形態で重要な役割を果たしたスプリングワッシャ５９は採用されていない。
【００５９】
前記菱形膨出突起５６０は、係止金具５２が係止姿勢に設定された状態で、長尺側の対角線Ｌ１と水平面との間で形成される角度αが、上下で隣設された菱形孔３８における上段の菱形孔３８の左隅部３８ｃと、下段の菱形孔３８の右隅部３８ｄとを結ぶ直線Ｌ２と水平面との間で形成される角度と同様になるように設定されているとともに、対角線Ｌ１の方が前記直線Ｌ２より若干短めに設定されている。
【００６０】
また、菱形膨出突起５６０の短尺側の対角線は、狭小隙間３８ａの隙間寸法より僅かに短く寸法設定されている。そして、菱形膨出突起５６０の左角部５６１が菱形孔３８の左隅部３８ｃに嵌り込むとともに、同右角部５６２が１段下の菱形孔３８の右隅部３８ｄに嵌り込むことにより、係止金具５２の昇降が阻止されるようになっている。
【００６１】
このように構成された菱形膨出突起５６０の中心位置には、軸体本体５１ａが摺接状態で貫通し得る嵌挿孔５５ａが穿設されている。かかる第２実施形態の位置決め具５０ａは、保持部材４０のコ字状部４３の挿通孔４３ｂおよび支柱本体３１の長孔３７を介して軸体本体５１ａを係止体５３の嵌挿孔５５ａに差し通し、軸体本体５１ａの先端部にかしめ処理を施すことにより、保持部材４０を支持した状態で支柱本体３１に装着される。
【００６２】
図８は、第２実施形態の位置決め具５０ａの作用を説明するための説明図であり、（イ）は、係止金具５２が係止姿勢に姿勢された状態、（ロ）は、係止金具５２が係止解除姿勢に姿勢設定された状態をそれぞれ示している。
【００６３】
まず、係止金具５２が係止姿勢に姿勢設定された状態では、図８の（イ）に示すように、左右一対のストッパー５８が支柱本体３１の各側板３３に当止した状態で、菱形膨出突起５６０の左角部５６１が所定の菱形孔３８の左隅部３８ｃに嵌り込むとともに右角部５６２が１段下の菱形孔３８の右隅部３８ｄに嵌り込み、これによって係止金具５２の昇降が規制された状態になっている。
【００６４】
この状態で一対の操作部５７を摘んで係止金具５２を軸体本体５１ａ回りに時計方向に回動させると、菱形膨出突起５６０の各角部５６１，５６２は、図８の（ロ）に示すように、菱形孔３８の各隅部３８ｃ，３８ｄから外れた状態になる。この状態で操作部５７を摘持して位置決め具５０を昇降させることができる。
【００６５】
そして、位置決め具５０を昇降させて新たな高さ位置が設定された後に、今度は操作部５７を軸体５１回りに反時計方向に回動させると、菱形膨出突起５６０の一対の角部５６１，５６２が、図８の（イ）に示すように、新たな高さ位置で菱形孔３８に嵌り込み、これによって保持部材４０、すなわち排水管Ｐの高さ位置が固定されることになる。
【００６６】
以上詳述したように、本発明の固定装置１０は、排水管Ｐを保持する保持部材４０と、この保持部材４０を所定の高さ位置で支持する支柱３０と、設定された保持部材４０の高さ位置を固定する位置決め具５０とを備えてなるものであり、支柱３０には複数の菱形孔３８が狭小隙間３８ａを介して連通するように連設されてなる上下方向に延びた長孔３７が設けられ、位置決め具５０は、菱形孔３８に嵌挿された状態で狭小隙間３８ａに阻止されて上下動が規制される係止姿勢と狭小隙間３８ａを通過し得る係止解除姿勢との間で姿勢変更可能な係止体５３と、該係止体５３の姿勢変更を操作するための操作部５７とを備え、係止体５３は、操作部５７のワンタッチ操作で係止姿勢および係止解除姿勢間で姿勢変更し得るように構成されてなるものである。
【００６７】
したがって、係止体５３が係止解除姿勢に姿勢設定された状態で操作部５７を摘持して上下方向に力を加えることにより、当該係止体５３を支柱３０に沿って昇降し、これによって位置決め具５０に接続された保持部材４０の高さ位置を調節することができる。
【００６８】
保持部材４０の高さ位置が調節された後に、操作部５７を所定の方向に操作して係止体５３を、その一部（係止突起５６または菱形膨出突起５６０）が長孔３７の狭小隙間３８ａを通過し得ない係止姿勢に姿勢変更することにより、係止体５３は昇降し得なくなるため、保持部材４０を、設定された高さ位置で支柱３０に固定することができる。
【００６９】
そして、係止体５３は、操作部５７のワンタッチ操作で係止姿勢および係止解除姿勢間で姿勢変更し得るように構成されているため、従来のようにボルト締め等の面倒な操作を行うことなく保持部材４０の高さ位置調節を容易に行うことができ、排水管Ｐ固定装置の現地施工の迅速性を確保することができる。
【００７０】
また、支柱３０には、上端縁から長孔３７に連通した開口３８ｂが設けられ、該開口３８ｂは、少なくとも係止解除姿勢に設定された係止体５３を通過し得るように口幅寸法が設定されているため、軸体５１を開口３８ｂから嵌め込むことによって係止体５３を支柱３０に装着することが可能になり、保持部材４０の支柱３０に対する装着操作が容易になる。特に支柱３０が２本の場合は、一対の支柱３０間の距離を予め設定した状態で一対の係止体５３を支柱３０頂部から各長孔３７に装着することが可能になり、保持部材４０の支柱３０に対する装着操作の迅速化に貢献することができる。
【００７１】
また、係止体５３を、支柱３０に昇降可能に取り付けられる異形板体５４と、該異形板体５４の片面に膨設され、且つ長孔３７に嵌挿された状態で狭小隙間３８ａを通過し得る隙間通過姿勢および同通過し得ない隙間非通過姿勢間で姿勢変更可能な係止突起（係止突起５６または菱形膨出突起５６０）とで構成し、係止突起の嵌挿孔５５ａに長孔３７の狭小隙間３８ａを通過し得る軸体５１が貫通し、該軸体５１を係止体５３、長孔３７および保持部材４０に抜け止め状態で嵌挿しているため、係止体５３を軸体５１回りに正逆回動させることによって係止突起が狭小隙間３８ａを通過し得る隙間通過姿勢（係止解除姿勢）と、同通過し得ない隙間非通過姿勢（係止姿勢）との間で当該係止体５３の姿勢変更を行うことができ、係止体５３の姿勢変更構造を簡単なものにすることができる。
【００７２】
また、特に第１実施形態においては、異形板体５４に支柱３０に対する対向面に膨出され且つ係止突起５６が膨設されてなる直状膨出突起５５を設け、該直状膨出突起５５を、係止突起５６が隙間通過姿勢に姿勢設定された状態で狭小隙間３８ａを通過し得るように長孔３７に嵌り込む一方、係止突起５６を隙間非通過姿勢に姿勢変更させることにより長孔３７から抜け出るように形状設定したため、係止体５３は、係止突起５６が狭小隙間３８ａを通過し得る隙間通過姿勢に姿勢設定されることにより直状膨出突起５５が長孔３７に嵌り込み当該長孔３７に案内されつつ昇降し得るようになり、この状態で係止体５３を昇降させて保持部材４０の高さ位置を調節することができる。
【００７３】
保持部材４０の高さ位置が設定された状態で操作部５７を軸体５１回りに所定の方向に向けて回動操作すれば、直状膨出突起５５がスプリングワッシャ５９の付勢力に抗して長孔３７から抜け出すとともに、直状膨出突起５５に設けられた係止突起５６が隙間非通過姿勢に姿勢設定された状態で菱形孔３８に嵌り込み、これによって係止体５３は昇降が阻止され、保持部材４０を高さ位置が固定された状態にすることができる。
【００７４】
そして、保持部材４０の高さ位置が固定された状態においては、直状膨出突起５５の長孔３７からの抜け出しにより付勢力が増加したスプリングワッシャ５９によって異形板体５４の支柱３０に対する押圧力が増大し、これによって係止体５３の係止姿勢が安定した状態になるため、保持部材４０の設定された高さ位置が変化するような不都合を有効に防止することができる。
【００７５】
本発明は、前記の実施形態に限定されるものではなく、以下の内容をも包含するものである。
【００７６】
（１）上記の実施形態においては、支持部材としての支柱３０は一対が採用され、当該一対の支柱３０で保持部材４０を挟持するようになされているが、本発明は、支柱３０が一対で設けられることに限定されるものではなく、１本のみの支柱３０であっても保持部材４０を支持することができる。そして、一対の支柱３０の場合には排水管Ｐの径寸法に合わせて一対の支柱３０間の距離を調節しなければならないが、支柱３０が１本の場合にはかかる面倒な操作を行う必要がなくなり、その分保持部材４０の支柱３０に対する装着操作の作業性が良好になるとともに汎用性が向上する。
【００７７】
（２）上記の実施形態においては、一対の支柱３０の内の一方のものだけがベース部材２０に案内されながら水平方向に移動し得るようになっているが、本発明は、一方の支柱３０のみが移動し得るように構成されていることに限定されるものではなく、両方の支柱３０が移動し得るように構成してもよい。
【００７８】
（３）上記の実施形態においては、保持部材４０が支柱３０に装着された状態で、配管抜止め部４２間を覆うカバー体を設けるようにしてもよい。これによって排水管Ｐの上方へ向かう抜け出しをより確実に防止することができる。
【００７９】
（４）上記の実施形態においては、保持部材４０に配管抜止め部４２が設けられているが、本発明は、保持部材４０に配管抜止め部４２を設けることに限定されるものではなく、排水管Ｐの敷設状況によっては特に設けなくても配管受け部４１のみで排水管Ｐを支持することができる。
【００８０】
（５）上記の実施形態においては、支柱本体３１の垂直板３４に穿設される長孔３７は、菱形孔３８の複数個が一部を重ね合せながら上下方向に連設されることによって形成されているが、こうする代わりに菱形孔３８の複数個を、一部を重ね合せることなく他とは独立した状態で穿設し、隣接する菱形孔３８間に狭小隙間３８ａに相当する連絡隙間を設けるようにしてもよい。
【００８１】
（６）上記の実施形態においては、装着孔として菱形形状を呈した菱形孔３８が採用されているが、本発明は、装着孔が菱形孔３８であることに限定されるものではなく、円孔や楕円孔であってもよいし、正方形状または長方形状を呈した横辺が水平方向へ延びる四角孔であってもよい。
【００８２】
（７）上記の実施形態においては、一対ある各係止突起５６または菱形膨出突起５６０の左右の角部（左角部５６１および右角部５６２）は、上下で１段ずれた菱形孔３８にそれぞれ嵌り込むように位置設定または形状設定されているが、本発明は、各係止突起５６または菱形膨出突起５６０の左右の角部が上下で１段ずれた菱形孔３８にそれぞれ嵌り込むことに限定されるものではなく、１つの菱形孔３８の左隅部３８ｃおよび右隅部３８ｄにそれぞれ嵌り込むようにしてもよい。
【００８３】
（８）上記の第２実施形態の位置決め具５０ａにおいては、軸体本体５１ａにスプリングワッシャ５９が外嵌されていないが、第２実施形態においても軸体本体５１ａにスプリングワッシャ５９を外嵌した上でかしめ止めを行うようにしてもよい。
【００８４】
（９）上記の実施形態においては、係止金具５２は常時露出しているが、カバー部材を被せるようにしてもよい。図９は、固定装置１０にカバー部材６０を装着する状態の組立て斜視図である。カバー部材６０は、断面視でコ字形状を呈した鋼材等の金属材料によって形成されており、対向する一対の側部６１，６１と、この側部６１，６１を連結する連結部６２とからなり、一枚の平板を折り曲げることにより形成される。
【００８５】
一対の側部６１，６１は、それぞれ相手側に向かって膨出した膨出部６３を備えており、それぞれ膨出部６３が係止金具５２の操作部５７に形成された装着孔５７ａに嵌まり込むことで、カバー部材６０が係止金具５２に装着される。より詳細に言えば、一対の側部６１，６１の内面の間隔を一対の操作部５７，５７の外面の間隔よりも広くすることで、カバー部材６０を係止金具５２に外挿可能とし、且つ一対の膨出部６３，６３の間隔を一対の操作部５７，５７の外面の間隔よりも狭くすることで、カバー部材６０の弾性復元力をもってカバー部材６０を係止金具５２に装着可能とする。加えて、膨出部６３および装着孔５７ａをそれぞれ長尺形状とすることで、係止金具５２に対してカバー部材６０が回動することはなくなり、係止金具５２およびカバー部材６０の両者が一体化される。
【００８６】
また、一対の側部６１，６１は、各先端が支柱３０の側板３３と対向するような、装着状態にて支柱３０を幅方向で挟み込む形状に設定されている。従って、カバー部材６０を係止金具５２の回動方向に回動させようとしても、側板６１が支柱３０に当止されることで、支柱３０に対してカバー部材６０が回動することはなくなり、支柱３０、係止金具５２およびカバー部材６０の三者が一体化される。
【００８７】
なお、支柱３０の側板３３と対向する各側部６１の先端のうち、係止金具５２の回動側位置には、側板３３に向かって膨出した膨出部６４が形成されており、実際にはこの膨出部６４が支柱３０の側板３３に当止されるようになっている。従って、一対の側部６１，１の内面の間隔を支柱３０の一対の側板３３，３３の外面の間隔よりもある程度広くすることで、支柱３０に対するカバー部材６０の先端の円滑な外挿を実現しつつ、一対の膨出部６４，６４の間隔を支柱３０の一対の側板３３，３３の外面の間隔と略同一にすることで、カバー部材６０の回動ガタを無くすことができる。
【００８８】
このように、カバー部材６０を装着することにより、係止金具５２が隠れ、美観上好ましいものになるという効果があり、また、係止金具５２が不用意に回動操作されにくくなるという効果もある。
【００８９】
また、係止金具５２が微小に回動して菱形孔（装着孔）３８に嵌り込んでいる係止突起５６がその装着孔３８から外れる程の大きな外力が排水管Ｐに加わったとしても、支柱３０、係止金具５２および規制部材として機能するカバー部材６０の三者が一体化されて係止金具５２の回動が規制されているため、位置決め具５０が昇降方向に動いて保持部材４０の高さ位置が狂うのを好適に防止することができる。
【００９０】
さらに、菱形孔（装着孔）３８に嵌り込んでいる係止突起５６がその装着孔３８を幅方向に拡開させてその装着孔３８から外れる程の大きな外力が排水管Ｐに加わったとしても、規制部材として機能するカバー部材６０によって装着孔３８の拡開（支柱３０の側板３３，３３の幅方向の拡開）が規制されているため、位置決め具５０が昇降方向に動いて保持部材４０の高さ位置が狂うのを好適に防止することができる。
【００９１】
（１０）図１０は、位置決め具５０ｂの第３実施形態を示す説明図であり、（イ）は、操作部５７０が係止解除姿勢に姿勢設定された状態、（ロ）は、操作部５７０が係止姿勢に姿勢設定された状態をそれぞれ示している。図１０に示すように、この実施形態においては、位置決め具５０ｂは、保持部材４０のコ字状部４３から外方に向かって縦置きで突設された平板状のブラケット５１０と、このブラケット５１０の先端部に支持軸５１１回りに回動自在に軸支された係止金具５２０とを備えて構成されている。
【００９２】
前記ブラケット５１０は、支柱本体３１の長孔３７０に貫通されるように保持部材４０のコ字状部４３からの突出量が設定されている。長孔３７０は、本実施形態においては、上下方向に直線状に延びるものが採用されており、先の実施形態のような菱形孔３８は設けられていない。
【００９３】
前記係止金具５２０は、支柱本体３１に隣設された係止体５３０と、この係止体５３０の基端部から外方に向かって延設された長尺の操作部５７０とからなっている。係止体５３０と操作部５７０とは略直角に結合され、その結合位置が前記支持軸５１１回りに回動自在に軸支されている。
【００９４】
前記係止体５３０は、係止金具５２０が係止姿勢に姿勢設定された状態（すなわち支柱本体３１が保持部材４０のコ字状部４３に密着した状態）で、図１０の（ロ）に示すように、支持軸５１１と支柱本体３１との間の水平距離より僅かに長く長さ設定されている。
【００９５】
かかる位置決め具５０ｂによれば、操作部５７０が支柱本体３１から外方に向けて突出することにより係止金具５２０が係止解除姿勢に姿勢設定された状態では、図１０の（イ）に示すように、支柱本体３１が保持部材４０のコ字状部４３から離間し、ブラケット５１０を長孔３７０に沿って昇降させることが可能になっており、これによって保持部材４０の高さ位置を調節し得るようになっている。
【００９６】
そして、図１０の（イ）に示す状態において、保持部材４０の高さ位置が設定された後に、操作部５７０を支持軸５１１回りに反時計方向に操作すれば、ブラケット５１０は支持軸５１１回りに反時計方向に回動し、ブラケット５１０の先端部が支柱本体３１を押圧してコ字状部４３を支柱本体３１側に引き寄せるため、係止金具５２０は、図１０の（ロ）に示すように、支柱本体３１をブラケット５１０の先端部とコ字状部４３との間に挟持した係止姿勢に姿勢設定されることになる。
【００９７】
そして、係止金具５２０が係止姿勢に姿勢設定された状態では、ブラケット５１０の先端部が支持軸５１１を通る水平線より下方位置に位置しているため、当該ブラケット５１０の先端部が支柱本体３１から受ける反力は支持軸５１１回りの反時計方向に向かうモーメントとして作用するため、係止金具５２０は支持軸５１１回りに時計方向に向けて回動することはなく、係止姿勢が維持されることになる。なお、係止金具５２０の係止姿勢を解除するに際しては、操作部５７０を支持軸５１１回りに時計方向に向けて回動操作すればよい。
【００９８】
【発明の効果】
本発明の流水部材の固定装置によれば、保持部材の高さ位置を固定するための位置決め具の構成要素である係止体は、操作部のワンタッチ操作で係止姿勢および係止解除姿勢間で姿勢変更し得るように構成されているため、従来のようにボルト締め等の面倒な操作を行うことなく保持部材の高さ位置調節を容易に行うことができ、流水部材固定装置の現地施工の迅速性を確保することができる。

[0004]
Such a fixing device 100 is laid on the concrete foundation S by screwing and fastening the anchor bolt 107 to the concrete foundation S via the base plate 101.
[0005]
[Problems to be solved by the invention]
By the way, since the drainpipe P is usually designed to allow sewage to flow out under natural flow, it is laid so as to be inclined downward from the upstream side toward the downstream side. Therefore, the height position of the band body 103 must be adjusted according to the inclination, and the height position is adjusted by rotating the nut 106 screwed to the screw shaft 102. Therefore, the lifting speed is very slow, and it takes a lot of time to perform the work for all the fixing devices 100 laid on the concrete foundation S, and the laying work of the drain pipe P is extremely inefficient. There was a problem that it would be.
[0006]
The present invention has been made in view of such circumstances, and it is possible to quickly adjust the height position while ensuring the secure fixing of the flowing water member, thereby improving the efficiency of laying work of the flowing water member. It is an object of the present invention to provide a fixing device for a flowing water member such as a drain pipe, a positioning tool for a holding member, and a regulating member for the positioning tool, which can achieve the above.

[0062]
FIG. 8 is an explanatory diagram for explaining the operation of the positioning tool 50a according to the second embodiment. (A) is a state in which the locking fitting 52 is in the locking posture, and (B) is a locking state. The state where the metal fitting 52 is set to the unlocking position is shown.
[0063]
First, in a state in which the locking fitting 52 is set to the locking position, as shown in FIG. 8A, a pair of right and left stoppers 58 is abutted against each side plate 33 of the column main body 31, and a rhombus is formed. The left corner 561 of the bulging projection 560 fits into the left corner 38c of the predetermined diamond-shaped hole 38, and the right corner 562 fits into the right corner 38d of the diamond-shaped hole 38 one step below. Elevation is restricted.
[0064]
In this state, when the pair of operation portions 57 is pinched and the locking fitting 52 is rotated clockwise around the shaft body 51a, the respective corners 561 and 562 of the rhombus bulge 560 are (B) of FIG. As shown in FIG. 5, the corners 38c and 38d of the diamond-shaped hole 38 are out of the way. In this state, the operation part 57 can be gripped and the positioning tool 50 can be raised and lowered.
[0065]
Then, after the positioning tool 50 is moved up and down to set a new height position, when the operation unit 57 is rotated counterclockwise around the shaft body 51, a pair of corners of the rhombus bulging projection 560 are formed. As shown in FIG. 8A, 561 and 562 are fitted into the rhombus hole 38 at a new height position, whereby the height position of the holding member 40, that is, the drain pipe P is fixed. .

[0067]
Therefore, by holding the operating portion 57 and applying a force in the vertical direction in a state where the locking body 53 is set to the unlocking posture, the locking body 53 is moved up and down along the column 30, Thereby, the height position of the holding member 40 connected to the positioning tool 50 can be adjusted.
[0068]
After the height position of the holding member 40 is adjusted, the operating portion 57 is operated in a predetermined direction to change the locking body 53 so that a part thereof (the locking projection 56 or the diamond-shaped bulging projection 560) is By changing the posture to the locking posture that cannot pass through the narrow gap 38a, the locking body 53 cannot move up and down, so that the holding member 40 can be fixed to the column 30 at the set height position.
[0069]
And since the locking body 53 is configured so that the posture can be changed between the locking posture and the unlocking posture by one-touch operation of the operation part 57, a troublesome operation such as bolt tightening is performed as in the related art. The height position of the holding member 40 can be easily adjusted without the need, and promptness of on-site construction of the drainage pipe P fixing device can be secured.
[0070]
In addition, the column 30 is provided with an opening 38b communicating with the elongated hole 37 from the upper end edge. The opening 38b has a width dimension such that the opening 38b can pass through at least the locking body 53 set in the unlocking position. Since the setting is made, the locking body 53 can be mounted on the column 30 by fitting the shaft body 51 through the opening 38b, and the mounting operation of the holding member 40 on the column 30 becomes easy. In particular, when the number of the columns 30 is two, the pair of locking members 53 can be attached to the respective elongated holes 37 from the top of the columns 30 with the distance between the pair of columns 30 set in advance, and the holding member 40 This contributes to speeding up the mounting operation on the column 30.
[0071]
Further, the locking body 53 passes through the narrow gap 38 a in a state in which the locking body 53 is mounted on the column 30 so as to be able to move up and down, and is inserted into the elongated hole 37 while being swelled on one surface of the deforming plate 54. Locking projections (locking projections 56 or diamond-shaped bulging projections 560) that can be changed in posture between a gap passing position that can be passed through and a gap non-passing position that cannot pass through. Since the shaft 51 that can pass through the narrow gap 38a of the long hole 37 penetrates and the shaft 51 is fitted in the locking body 53, the long hole 37 and the holding member 40 in a retaining state, the locking body 53 By rotating the shaft forward and backward around the shaft body 51, a gap passing posture (an unlocking posture) in which the locking protrusion can pass through the narrow gap 38a, and a gap non-passing posture (a locking posture) in which the locking protrusion cannot pass the narrow gap 38a. The posture of the locking body 53 can be changed between The momentum change structure can be as simple.

The bulging portion 64 is adapted to be abutted on the side plate 33 of the column 30. Therefore, by making the interval between the inner surfaces of the pair of side portions 61, 1 wider than the interval between the outer surfaces of the pair of side plates 33, 33 of the column 30, a smooth extrapolation of the tip of the cover member 60 with respect to the column 30 is realized. In addition, by making the interval between the pair of bulging portions 64, 64 substantially equal to the interval between the outer surfaces of the pair of side plates 33, 33 of the column 30, rotation backlash of the cover member 60 can be eliminated.
[0088]
By attaching the cover member 60 in this manner, there is an effect that the locking fitting 52 is hidden and becomes beautifully preferable, and an effect that the locking fitting 52 is less likely to be inadvertently rotated. is there.
[0089]
Further, even if the locking fitting 52 is slightly rotated and a large external force is applied to the drain pipe P such that the locking projection 56 fitted into the diamond-shaped hole (mounting hole) 38 comes off the mounting hole 38, Since the support 30, the locking member 52, and the cover member 60 functioning as a restricting member are integrated and the rotation of the locking member 52 is regulated, the positioning member 50 moves in the vertical direction and the holding member 40 moves. It is possible to preferably prevent the height position from being out of order.
[0090]
Further, even if a large external force is applied to the drain pipe P such that the locking projection 56 fitted into the diamond-shaped hole (mounting hole) 38 expands the mounting hole 38 in the width direction and separates from the mounting hole 38. Since the expansion of the mounting hole 38 (expansion of the side plates 33, 33 in the width direction of the column 30) is restricted by the cover member 60 functioning as a restricting member, the positioning member 50 moves in the elevating direction to move the holding member 40. It is possible to preferably prevent the height position from being out of order.
