Description

【０００１】
【発明の属する技術分野】
本発明は、排水栓装置、更に詳しくは操作部の押し釦を押動操作する度にロックとロック解除を交互に繰り返して排水栓を開栓・閉栓するスラストロック機構を作動部として有する排水栓装置に関するものである。
【０００２】
【従来技術】
従来、排水栓装置として特開平８−１７７１００号公報（前者）が存在する。
この先行技術は、図１３に示すようにレリースワイヤ３のアウターチューブ２３端部に鍔部２３１を周設し、その鍔部２３１をジョイント金具９の押し釦ケース２１側ではない逆側の端部に形成した収容凹部１９に収容し、その収容凹部１９内の前記鍔部２３１とアウターチューブ２３外周面との間にアウターチューブ２３に遊嵌する回転案内用リング材１０を介装し、そのジョイント金具９を回転案内用リング材１０に固定すると共にそのジョイント金具９の押し釦ケース２１側の端部を押し釦ケース２１の下端に設けた螺子孔２１’に螺着して構成した操作部１とレリースワイヤ３との連結構造を開示している。
この操作部１は、ジョイント金具９を挿通して上方に突出するインナーコア１３の上端を押し釦３１の軸３１１に連結した状態でその軸３１１を押し釦ケース２１に開孔した通孔２１２下方開放部から上方に向けて挿入しながらジョイント金具９に押し釦ケース２１の螺子孔２１’に螺着させる構造のものであり、回転案内用リング材１０が、アウターチューブ２３の鍔部２３１に係止して抜けを防止した状態でアウターチューブ２３と無関係にジョイント金具９と共回りして、レリースワイヤ３を回転させることなくジョイント金具９を押し釦ケース２１に連結可能にしている。
前記するレリースワイヤの他端は、排水栓に設けたスラストロック機構からなる作動部に連結されている。
また、本出願人提案の技術として特願平１１−３６８４０２号（後者）開示の容体内レリースワイヤ配線タイプの排水栓装置も存在する。
この先行技術は、排水栓２に設けたスラストロック機構５２を作動部とした容体内レリース配線タイプの排水栓装置であり、その排水栓を、図１４に示すように排水口１０１内の口芯に配設した有底筒状の案内部１２と、栓蓋２２から垂設され前記案内部１２に上下動可能な案内される内部中空な昇降体３２と、その昇降体３２の底部から同昇降体３２内に一端側が挿入され他端部を案内部１２の底部に係止した支軸４２と、前記栓蓋２２を貫通して昇降体３２内に位置するレリースワイヤ３他端側のインナーコア１３と、支軸４２と昇降体３２との間に設けられ操作部の押動操作によるインナーコア１３の前進で同インナーコア１３他端を支軸４２に形成されている凹部４２１底に突き当てて昇降体３２と共に栓蓋２２を持上げロックして開栓し次のインナーコア１３の前進でそのロックを解除して閉栓するスラストロック機構５２とを有する構成としている。
【０００３】
しかしながら、前者では、レリースワイヤ３を操作部（詳細には押し釦ケース）１に連結するに際してジョイント金具９の螺子込みが必須であり、プライヤー等の工具での増し締めも必要となるため、生産工場での操作部に対するレリースワイヤの組付け作業が非常に面倒である。
また、ジョイント金具９が押し釦ケース２１の下端から露出することから、例えば浴槽、流し、洗面器等の容体、特に浴槽内にレリースワイヤを配線するタイプの排水栓装置においては、押し釦ケース２１の下部に露出するジョイント金具９で入浴者が怪我をする問題をも有している。
更に、閉栓状態で踏みつける等して押圧力が排水栓（栓蓋）に掛かっている状態で誤って押し釦を押動操作するアクシデント時に、インナーコアが座屈変形する虞れがあった。
また、後者においては、開栓状態で図１４に示すように支軸４２の上方のインナーコア１３が昇降体３２内の空間に臨むことから、開栓状態から押し釦３１を押動操作してロックを解除した段階で押し釦３１を押しっぱなしのまま誤って栓蓋２２に負荷荷重がかかるアクシデントによって、凹部４２１上方部位の昇降体３２内空間でインナーコア１３部分が座屈変形する問題が発生する（二点鎖線参照）。この問題は、清掃時に発生したり、子供が悪ふざけをした時等に発生する。このように座屈変形が生じると排水栓装置の分解を伴うインナーコア１３の交換を強いられ、交換作業が非常に面倒になってしまう。
【０００４】
【発明が解決しようとする課題】
本発明は上記従来事情に鑑みてなされたもので、その目的とする処は、操作部に対するレリースワイヤの連結作業が簡単で、しかも金具が外部に露出しない排水栓装置を提供することにある。
他の目的とする処は、閉栓状態で踏みつける等して押圧力が栓蓋に掛かっている状態で誤って押し釦を押動操作してもインナーコアが座屈する虞れがない排水栓装置を提供することにある。
また、更に他の目的とする処は、排水栓にスラストロック機構を作動部として有する容体内レリース配線タイプの排水栓装置において、開栓状態から押し釦を押動操作してロックを解除した段階で押し釦を押っぱないしのまま誤って栓蓋に負荷荷重がかかってもインナーコアが座屈する虞れがない排水栓装置を提供することにある。
【０００５】
【課題を解決するための手段】
上記目的を解決するために講じた技術的手段は、浴槽、流し、洗面器等の容体に設けられた排水栓にレリースワイヤを介して連結された操作部の押動操作で前記排水栓を開閉する排水栓装置において、前記操作部における押し釦ケースに押し釦側とは逆側から凹設された凹窪部にレリースワイヤ一端側を挿入してそのレリースワイヤから突出するインナーコアを押し釦で押動可能とし、レリースワイヤにおけるアウターチューブ一端に形成された鍔部を凹窪部底に当て付けられたワッシャー部材に当接し、該アウターチューブに外嵌状に設けられて一端が前記鍔部に当接もしくは近接するリング状部材の他端を、前記凹窪部に連通して押し釦ケースの側部に開孔した差込孔からレリースワイヤを避けて差し込まれて凹窪部に係止される止め部材で直接的もしくは間接的に支承していることを特徴とするものである（請求項１）。
前記止め部材は、差込時にレリースワイヤと干渉しない開放部を前方側を開放した平面視形状に形成する。そして、凹窪部内面には差し込まれる止め部材が係止する係止凹部が凹設形成されている。
そして、前記間接的に支承とは、介在部材を介して支承することを指し、介在部材の一例としては凹窪部とアウターチューブとの間を水密状に閉塞するＯリングが挙げられる。
また、前記する止め部材は、ＰＯＭ等の合成樹脂材で成形されている。
【０００６】
前記技術的手段によれば、押し釦ケースに凹設されている凹窪部底に同凹窪部開放部から挿入するワッシャー部材を当接させ、次にリング状部材を外嵌した状態でレリースワイヤの一端側をその凹窪部開放部から挿入し、しかる後、押し釦ケースの側部に開孔してある差込孔から差し込み凹窪部に係止される止め部材でリング状部材を支承する。
これによってレリースワイヤにおけるアウターチューブ一端の鍔部はワッシャー部材と止め部材で支承されるリング状部材とで抜けないように支持され、そのアウターチューブから突出するインナーコアは押し釦ケースに上下動可能に挿嵌される押し釦の軸で押動可能となる。
従って、ワッシャー部材、リング状部材を外嵌状に備えたレリースワイヤの一端側を順次凹窪部の開放部から挿入し、そして側方から止め部材を差し込む簡単な作業でレリースワイヤの操作部（詳細には押し釦ケース）への連結作業が終了する。
【０００７】
また、浴槽、流し、洗面器等の容体に設けられた排水栓にレリースワイヤを介して連結された操作部の押動操作で前記排水栓を開閉し、該操作部を容体の内壁面に設けた排水栓装置において、前記操作部における押し釦ケースに押し釦側とは逆側から凹設された凹窪部にレリースワイヤ一端側を挿入してそのレリースワイヤから突出するインナーコアを押し釦で押動可能とし、レリースワイヤにおけるアウターチューブ一端に形成された鍔部を凹窪部底に当て付けられたワッシャー部材に当接し、該アウターチューブに外嵌状に設けられて一端が前記鍔部に当接もしくは近接するリング状部材の他端を、前記凹窪部に連通して押し釦ケースの側部に開孔した差込孔からインナーコアを避けて差し込まれて凹窪部に係止される止め部材で間接的に支承してなり、前記間接的に支承させる手段が、止め部材とリング状部材との間に介在されて凹窪部とアウターチューブとの間を閉塞する環状のシール部材である場合も有効なものである（請求項２）。
この環状のシール部材の一例としてＯリングが挙げられる。
【０００８】
前記技術的手段によれば、容体内レリースワイヤ配線タイプの排水栓装置でありながら、請求項１と同様な簡単な作業でレリースワイヤの操作部（詳細には押し釦ケース）への連結が行える上、インナーコアへの凹窪部からの水の進入が凹窪部を閉塞する環状のシール部材で防止される。
【０００９】
そして、更にリング状部材の前記一端がアウターチューブの鍔部に当接もしくは近接する鋭利形状に形成してあると好適なものである（請求項３）。
【００１０】
前記技術的手段によれば、アウターチューブの引張り方向に対して鍔部に食込んでアウターチューブの抜け強度を増強する。
【００１１】
更に、容体内レリースワイヤ配線タイプ、容体外レリースワイヤ配線タイプに関らず、ワッシャー部材がアウターチューブの鍔部外面と凹窪部内面との空間を閉塞して凹窪部に嵌挿され前記鍔部を嵌合する有底筒状を呈していると更に好適なものである（請求項４）。
【００１２】
前記技術的手段によれば、ワッシャー部材、リング状部材を外嵌挿したレリースワイヤの一端側を順次凹窪部の開放部から挿入する必要上、アウターチューブの鍔部回りと凹窪部内面との間に空間（クリアランス）が生じる。その空間（クリアランス）のため、閉栓状態に踏みつける等して栓蓋に押圧力が掛かっている状態で押し釦を誤って押動操作すると、栓蓋を押し上げられずに逃げ場を失うインナーコアは、前記空間（クリアランス）で逃げて屈曲しその部分で座屈変形を起してしまう。その座屈変形の原因となる逃げ場をアウターチューブの鍔部と凹窪部内面との空間（クリアランス）を閉塞する有底筒状のワッシャー部材で無くす。
その際、インナーコアには圧縮力が作用するが、インナーコアが金属材からなるコイル状のものの場合には、自らの圧縮で対応し、非圧縮性のインナーコアの場合には、アウターチューブの弾性的な伸延で対応する。
【００１３】
また、浴槽、流し、洗面器等の容体に設けられた排水栓にレリースワイヤを介して連結された操作部の押動操作で前記排水栓を開閉する排水栓装置において、前記操作部における押し釦ケースに押し釦側とは逆側から凹設された凹窪部にレリースワイヤ一端側を挿入してそのレリースワイヤから突出するインナーコアを押し釦で押動可能とし、レリースワイヤにおけるアウターチューブ一端に形成された鍔部を凹窪部底に当て付けられたワッシャー部材に当接すると共にそのワッシャー部材に対して前記鍔部を挟んでアウターチューブに外嵌挿されるバネ受け部材を設け、そのバネ受け部材と、前記凹窪部に連通して押し釦ケースの側部に開孔された差込孔からレリースワイヤを避けて差し込まれて同凹窪部に係止する止め部材とに亘って圧縮弾機を介在している場合も有効なものである（請求項５）。
【００１４】
この前記技術的手段によれば、押し釦ケースに凹設されている凹窪部底に同凹窪部開放部から挿入するワッシャー部材を当接させ、バネ受け部材、圧縮弾機を外嵌挿した状態でレリースワイヤの一端側をその凹窪部開放部から挿入し、しかる後、押し釦ケースの側部に開孔してある差込孔から差し込み凹窪部に係止される止め部材で圧縮弾機の前記鍔部とは逆側の端部を支承する。
これによってレリースワイヤにおけるアウターチューブ一端の鍔部は止め部材と圧縮弾機の弾撥力を受けたバネ受け部材で抜けないように支持され、そのアウターチューブから突出するインナーコアは押し釦ケースに上下動可能に挿嵌される押し釦の軸で押動可能となる。
従って、ワッシャー部材、バネ受け部材、圧縮弾機を外嵌挿したレリースワイヤの一端側を順次凹窪部の開放部から挿入し、そして側方から止め部材を差し込む簡単な作業でレリースワイヤの操作部（詳細には押し釦ケース）への連結作業が終了する。
また、閉栓状態に踏みつける等して栓蓋に押圧力が掛かっている状態で押し釦を誤って押動操作すると、栓蓋を押し上げられずに逃げ場を失うインナーコアの変形でアウターチューブに弾性的な伸延応力が生じる。その際、圧縮弾機を圧縮してアウターチューブの端部間を接近させ、それによってアウターチューブがインナーコアの圧縮による逃げ場を確保して、インナーコアの座屈変形を防止する。
【００１５】
そして、前記排水栓装置がその操作部を容体の内壁部に設けられる容体内レリース配線タイプであり、且つ前記止め部材と圧縮弾機との間に前記凹窪部とアウターチューブとの間を閉塞する環状のシール部材を介在している場合には、前記と同様にインナーコアへの凹窪部からの水の進入が凹窪部を閉塞する環状のシール部材で防止する上で好適である（請求項６）。
【００１６】
また、操作部を容体の内壁部に設けた容体内レリース配線タイプにおいて、押し釦ケースが容体の内壁部に設けられるベース板に取り付けられ、前記差込孔がベース板に相対して開孔されていると、止め部材がベース板で隠されることから、入浴者にとってより安全設計である（請求項７）。
【００１７】
また、容体内レリースワイヤ配線タイプの排水栓装置において、排水栓が、排水口内の口芯に配設した有底筒状の案内部と、栓蓋から垂設され前記案内部に上下動可能な案内される内部中空な昇降体と、その昇降体の底部から同昇降体内に一端側が挿入され他端部を案内部の底部に係止した支軸と、前記栓蓋を貫通して昇降体内に位置するレリースワイヤ他端側のインナーコアと、支軸と昇降体との間に設けられ操作部の押動操作によるインナーコアの前進で同インナーコア他端を支軸に形成されている凹部底に突き当てて昇降体と共に栓蓋を持上げロックして開栓し次のインナーコアの前進でそのロックを解除して閉栓するスラストロック機構とを有する構成とし、前記栓蓋もしくは昇降体から昇降体内に向けてインナーコアの案内筒を垂設し、該案内筒を前記支軸の凹部に僅かなクリアランスを介して遊嵌もしくは摺接関係に構成し、且つ案内筒の垂設長さを前記ロック解除状態において該案内筒が前記凹部内に位置する長さにしている場合も有効なものである（請求項８）。
【００１８】
前記技術的手段によれば、押し釦を押動操作してインナーコアを前進させてインナーコア他端を支軸に形成されている凹部底に突き当てて昇降体と共に栓蓋を持上げてスラストロック機構をロックして開栓し、次の押し釦の押動操作によるインナーコアの前進でスラストロック機構のロックを解除して閉栓する。
その開栓状態から押し釦を押動操作してロックを解除した段階で押し釦を押しっぱなしのまま誤って踏みつける等して押圧力が栓蓋に作用した際のインナーコアの外方への逃げが案内筒で妨げられ、インナーコアの座屈変形が防止される。座屈変形はないもののインナーコアには圧縮力が作用するが、インナーコアが金属材からなるコイル状のものの場合には、自らの圧縮で対応し、非圧縮性のインナーコアの場合には、アウターチューブの弾性的な伸延で対応すること前記と同様である。
前記開栓状態から押し釦を押動操作してロックを解除した段階で押し釦を押しっぱなしのまま誤って踏みつける等して押圧力が栓蓋に作用する条件とは、即ち押し釦側と栓蓋側双方からの負荷荷重が作用する条件とは、例えば浴槽では清掃後給水する際に押し釦を押動操作してロックを解除した後に滑って押し釦を押動したまま足で栓蓋を踏みつけた場合や、子供が槽内で遊んでいる最中に手による押し釦の押動操作と栓蓋に掛かる人体荷重の相互作用がほぼ同時に行なわれた時等に発生する。
【００１９】
【発明の実施の形態】
図１〜図９は本発明排水栓装置の第１の実施の形態を、図１０は同第２の実施の形態を、図１１及び図１２は、同第３の実施の形態を各々示している。まず第１の実施の形態を説明すると、符号Ａは排水栓装置である。
【００２０】
この排水栓装置Ａは、操作部１と、容体１００の底に設けられている排水栓２と、前記操作部１と排水栓２とを連結する遠隔操作用のレリースワイヤ３とから構成されている。
【００２１】
操作部１は、図１、図８に示すようにベース板１１と、押し釦ケース２１と、押し釦３１とから構成されており、そのベース板１１は、例えば浴槽（容体）１００の内壁面に両面テープ、ボルト・ナット等の取付手段２００で取付け固定されており、そのベース板１１から浴槽１００内に向けて起設した引っ掛け片（図示せず）に押し釦ケース２１を係脱可能に係止し、その押し釦ケース２１に先端に押し釦３１を取付けた軸３１１が上下動可能に挿入されている。
【００２２】
押し釦ケース２１は、ＡＢＳ樹脂等の耐熱性の合成樹脂製であり、ベース板１１側及び上端側を開放した正面視略縦長矩形状を呈してなり、各稜線部を湾曲状にして入浴者の肌に対して優しい外観形状にしてある。
また、この押し釦ケース２１は、押し釦３１側とは逆側、即ち下側から凹設された凹窪部２１１を備えると共に、その凹窪部２１１底に連通してその凹窪部２１１よりも小径な前記軸３１１用の通孔２１２を開孔し、下端近傍の側部、詳細にはベース板１１側から前記凹窪部２１１に連通する差込孔２１３を開孔している。
【００２３】
前記押し釦ケース２１へのレリースワイヤ３一端の取付けは、本実施の形態においては２枚のワッシャー部材４、リング状部材５、環状のシール部材（例えばＯリング）６、止め部材７を使用して行なわれる。
【００２４】
レリースワイヤ３は、インナーコア１３と、そのインナーコア１３を摺動可能な案内するアウターチューブ２３とからなっており、その両端にフレア加工で鍔部２３１を周設した構成になっており、インナーコア１３をその両端から突出させてある。
【００２５】
リング状部材５は、金属製もしくは合成樹脂製であり、レリースワイヤ３のアウターチューブ２３に遊外嵌され、鍔部２３１に相対する端部を鋭利形状、即ち尖頭状の鋭利部１５が形成されている。
【００２６】
止め部材７は、ＰＯＭ等の合成樹脂材で成形されており、図３に示すように、下半部を凹設することによって上半部に差込用段突部１７１、１７１を両側面部に突設状に有する平面視矩形状の本体１７の中央部に前側を開放したレリースワイヤの通孔１７２を開孔し、その通孔１７２の内面形状を縦断面視で先窄み形状とし、後面部に下側に向けて位置決め片１７３を垂設した構成になっている。
また、止め部材７の前側開放部は、差込時に干渉せずにレリースワイヤ３を通孔１７２に導く程度の広さを有している。
【００２７】
前記差込孔２１３は、本実施の形態においては、ベース板１１に面する側に開孔されており、且つその入口部分に前記止め部材７後面部の位置決め片１７３を位置決めする凹段部２１３ａが凹設してある。
【００２８】
前記凹窪部２１１は、前記差込孔２１３に連続して前記止め部材７の差込用段突部１７１、１７１を係止させるために係止起立片２１４、２１４を内面に突設形成しており、止め部材７を差込孔２１３から位置決め片１７３が凹段部２１３ａに位置決めされるまで差し込むと、係止起立片２１４、２１４が前記差込用段突部１７１、１７１を自ずと係止するようになっている。
【００２９】
押し釦３１は、押し釦ケース２１と同様にＡＢＳ樹脂等の耐熱性の合成樹脂製であり、下面及び後面を開放した箱状を呈してなり、軸３１１先端に取付けられて押し釦ケース２１の上側開放部の外面に沿って上下動する大きさに形成されている。
【００３０】
環状のシール部材６は、レリースワイヤ３に水密状に嵌合されており、凹窪部２１１にセットした際、その凹窪部２１１内面との間を閉塞する所定の径のものを使用する。
【００３１】
押し釦ケース２１にレリースワイヤ３一端を取付ける際には、レリースワイヤ３に環状のシール部材（例えばＯリング）６、下位のワッシャー部材４、リング状部材５を順次嵌挿させた後、上位のワッシャー部材４をアウターチューブ２３の鍔部２３１上に載置（位置）させた状態でインナーコア１３の先端を押し釦３１の軸３１１下端に連結し、その状態で軸３１１を凹窪部２１１の下端開放部から通孔２１２に挿入する。続いて差込孔２１３から止め部材７を差込み係止する。すると止め部材７上面で環状のシール部材６が若干圧潰されてその弾性力で凹窪部２１１底に位置決めされる上位のワッシャー部材４とリング状部材５先端の鋭利部１５でアウターチューブ２３の鍔部２３１が軽く挟持され、抜け止め不能となる。無論、止め部材７を差込係止した状態でリング状部材５先端の鋭利部１５がアウターチューブ２３の鍔部２３１に近接するレイアウトすること自由である。
しかる後、軸３１１に押し釦３１を取付け、押し釦ケース２１をベース板１１に係止して操作部１のセットは完了する。
【００３２】
図１、図８は、各々排水栓が閉栓状態、開栓状態の時の操作部１を示している。

【００３５】
案内部１２は、前記排水口部材１０１ａに設けた支持ブラケット１０１ａ’に一体に成形したり、そのブラケット１０１ａ’に嵌合係止された有底筒体であり、内径を、前記昇降体３２を上下案内可能とすべくその昇降体３２よりも僅かながら大径に形成されている。
尚、前記昇降体３２の外面には係合用凸条（図示せず）を等間隔をおいて突設する一方、案内部１２の外面にはその係合用凸条を上下方向にスライド可能に案内する係合用案内溝（図示せず）を凹設し、両者の係合関係で横振れを起すことなく、昇降体３２が上下動するように配慮されている。
【００３６】

固定歯５２３と係止歯５２２とは、互いに前述した鋸状歯部５２３ａ、５２２ａが向かい合うように対向配置されている。
固定歯５２３は、昇降体３２における底部、詳細には、昇降体３２の下開放部を閉塞するキャップ３２３に前述した鋸状歯部５２３ａを形成することで構成されている。
係止歯５２２は、昇降体３２の側壁に、互いに９０度の間隔を空けて４個形成されており、この４個の係止歯５２２…の下端に夫々前述した鋸状歯部５２２ａが形成されている。
前記昇降体３２における前記４個の係止歯５２２…相互の間には、前記回転リング５２１における上側の係合歯部５２１ａが案内される溝部３２’が刻設されている。
スプリング５２４は、前記昇降体３２の底部と、回転リング５２１を抜止不能とする前記下側の鍔部４２１との間に圧縮状に介在させてある。
【００３７】
栓蓋２２は、円板部２２１と、その円板部２２１に係着する凸曲面状の蓋部２２２とからなる内部中空状を呈してなり、蓋部２２２の側方から栓蓋２２の中央側に向けて上向き傾斜状にレリースワイヤ３の他端側（下端側）を導入して保持している。
【００３８】
前記レリースワイヤ３の栓蓋２２内への保持部は、円板部２２１から立ち上げ形成した立ち上げ部２２１ａの頂底と、その立ち上げ部２２１ａと相対する蓋部２２２の内面に凹設したガイド溝２２２ａの底とでレリースワイヤ３を抱持している。
符号２２２ｂは、前記ガイド溝２２２ａ縁から垂設して前記立ち上げ部２２１ａの両側面に当接して立ち上げ部２２１ａを挟持する前後一対の位置決め片である。
【００３９】
また、レリースワイヤ３の他端側は、栓蓋２２を挿通させて前記抱持部先端から同レリースワイヤを下向きに湾曲させ、その先端を、円板部２２１において昇降体３２の真上部分に水密状に連結させてある。
【００４０】
前記水密状の連結部は、円板部２２１の丁度中央部において大径凹部２２１ｂと小径凹部２２１ｃとを上下２段にして同芯をもって凹設すると共に下段の小径凹部２２１ｃ底にインナーコア１３のみを昇降体３２内に通す通し孔２２１ｄを開孔し、前記レリースワイヤ３におけるアウターチューブ２３先端を小径凹部２２１ｃ底に位置決めすると共に大径凹部２２１ｂの底にアウターチューブ２３に固定したワッシャー２３２を配置し、その上にＯリングＯをその一部が上方に突出するように同大径凹部２２１ｂ内に嵌合し、大径凹部２２１ｂ、小径凹部２２１ｃを挟んで円板部２２１に設けた一対のレール２２１ｅ、２２１ｅに２又状の係止片２２１ｆ’、２２１ｆ’を有する係止体２２１ｆを抜差し可能に係止して前記ＯリングＯを圧潰し、それによってアウターチューブ２３の他端（下端）が円板部２２１に水密状に連結されて、インナーコア１３のみが昇降体３２内に突出させてある。
【００４１】
インナーコア１３の他端（下端）は、前記通し孔２２１ｄに連通して円板部２２１から垂設した案内筒２２１ｇを通って、図示するように支軸４２の上端側から凹設した凹部４２１底に当接もしくは接近するように位置させてある。
前記案内筒２２１ｇは、ロック解除状態においても凹部４２１内に位置する程度を最低限の長さとして垂設されている（図９参照）。また、この案内筒２２１ｇは、支軸４２の凹部４２１に対して僅かなクリアランスを介して遊嵌もしくは摺接する関係になっている。
【００４２】
また、前記支軸４２下端部と案内部１２の底部との間には、支軸４２の下端部が係止される係止手段８が構成されている。
【００４３】
この係止手段８は、前記案内部１２の底に形成した係止孔１８と、支軸４２の下端部に近傍に凹設した係止凹部２８とで構成されており、その係止孔１８に係止凹部２８が係止され、それによって支軸４２は上下移動不能になっている。
本実施の形態では、少なくとも支軸４２の下端部位を軸方向に２分するように切り割りして若干の弾性を持たせるようにしてある。
【００４４】
このように構成されている排水栓２の作動を順を追って説明すると、
図２に示す状態は、閉栓状態である。この閉栓状態では、回転リング５２１の上下の係合歯部５２１ａ、５２１ａは、溝部３２’の上端域に位置している。
この図２に示す係止状態、即ち図６から押し釦３１を押動操作すると、インナーコア１３が前進して支軸４２を押動するが、支軸４２下端部が前記係止手段８で上下移動不能に係止されていることから行き場を失ったインナーコア１３は、昇降体３２を上昇させることになる。詳細にはスプリング５２４を圧縮しながら前記回転リング５２１の下側の係合歯部５２１ａが溝部３２’で案内されると共に固定歯５２３の鋸状歯部５２３ａに、同下側の係合歯部５２１ａが接触して、（図７（ａ））に示すようにその鋸状歯部５２３ａの斜面に沿って移動するまで昇降体３２は上昇する（矢印が示す方向は、昇降体３２の上下動及び回転リング５２１の回転方向を示し、以下の（ｂ）（ｃ）（ｄ）も同様である。）。そして、押し釦３２の押動操作を停止すると、図７（ｂ）に示すように上記スプリング５２４の付勢力を受けて下降する係止歯５２２の鋸状歯部５２２ａに回転リング５２１における上側の係合歯部５２１ａが係止し、栓蓋２２を排水口１０１から上方に離間させて開口（開栓）する（図９）。尚、開栓時には、支軸４２の凹部４２１内に、インナーコア１３の案内筒２２１ｇの先端が少なくとも位置するレイアウトになる。
この開栓状態から再び閉栓状態にする時には、押し釦３１を押動操作して、スプリング５２４の付勢力に抗して昇降体３２をいったん上昇させて固定歯５２３の鋸状歯部５２３ａに回転リング５２１の下側の係合歯部５２１ａを接触させると共にその鋸状歯部５２１ａの斜面に沿ってその下側の係合歯部５２１ａを移動させ（図７（ｃ））、そして、押し釦３１の押動操作を停止すると、スプリング５２４の付勢力で下降する係止歯５２２の鋸状歯部５２２ａの斜面で回転リング５２１の上側の係合歯部５２１ａが案内されながら同上側の係合歯部５２１ａが溝部３２’に導かれて（図７（ｄ））昇降体３２を前記する図２まで下降させ、閉口（閉栓）する。
【００４５】
従って、斯様な構成になっている排水栓装置においては、プライヤー等の特殊工具を使用して螺子込む作業を遂行することなく、ワッシャー部材４、４、リング状部材５、シール部材６のレリースワイヤ３への外嵌挿、止め部材７の差込によって金属部材が外部に露出することなく操作部１にレリースワイヤ３の一端側を連結することができる。
また、開栓時には、支軸４２の凹部４２１内に、インナーコア１３の案内筒２２１ｇの先端が少なくとも位置するレイアウトになっているため、開栓状態から押し釦３１を押動操作してロックを解除した段階で誤って押し釦３１を押動操作しっぱなしで栓蓋２２を踏みるようなアクシデントが生じることになっても、案内筒２２１ｇでインナーコア１３の昇降体３２内空間への逃げが防止される（図９参照）。
【００４６】
次に図１０で示す第２の実施の形態を説明すると、この実施の形態は、前記する上位のワッシャー部材４が、前記アウターチューブ２３の鍔部２３１外周面と凹窪部２１１内面との空間（クリアランス）Ｓを閉塞する有底筒状に形成した振れ防止用の筒状部１４を有すること以外、前記する第１の実施の形態と同様であるため、同一符号を付けて説明は省略する。
【００４７】
前記する第１の実施の形態では、上下のワッシャー部材４、４、リング状部材５を外嵌挿したレリースワイヤ３の一端側を順次凹窪部２１１の開放部から挿入する必要上、アウターチューブ２３の鍔部２３１回りと凹窪部２１１内面との間に空間（クリアランス）Ｓが生じる（図１、図８参照）。閉栓状態に踏みつける等して栓蓋２２に押圧力が掛かっている状態で押し釦３１を誤って押動操作したりすると、逃げ場を失うインナーコア１３は、前記空間Ｓで逃げて屈曲しその部分で座屈変形を起してしまう。その座屈変形の原因となる逃げ場をアウターチューブ２３の鍔部２３１と凹窪部２１１内面との空間Ｓを閉塞する振れ防止用の筒状部１４で無くす構造である。
この筒状部１４は、レリースワイヤ３の一端を操作部１に連結する凹窪部２１１への差込時に丁度嵌合される程度の径に形成されている。
押し釦ケース２１にレリースワイヤ３一端を取付ける順序は、前記第１の実施の形態と同様であるため、省略する。
【００４８】
次に図１１、図１２で示す第３の実施の形態を説明すると、この実施の形態は、前記するリング状部材を省略する代わりに、前記する筒状部１４を有するワッシャー部材４に対してアウターチューブ２３の鍔部２３１を挟んでアウターチューブ２３に外嵌挿するバネ受け部材４’を設け、そのバネ受け部材４’と、環状のシール部材７すぐ上のワッシャー部材４との間に圧縮弾機Ｂを介在した構造になっている。
前記バネ受け部材４’と、環状のシール部材６すぐ上のワッシャー部材４は共に平ワッシャーである。
前記圧縮弾機Ｂは、バネ受け部材４’と、止め部材７上の環状のシール部材６とに亘って介在してある。
【００４９】
この実施の形態では、図１１に示すように、通常時において圧縮弾機Ｂの弾撥力でアウターチューブ２３１はワッシャー部材４を介して間接的に凹窪部２１１に弾接している。そして、例えば閉栓状態に踏みつける等して栓蓋２２に押圧力が掛かっている状態で押し釦３１を誤って押動操作した場合に、インナーコア１３に圧縮力が生じるが、アウターチューブ２３の鍔部２３１がバネ受け部材４’を介して圧縮弾機Ｂを圧縮するように端部間を接近させるように下降して（図１２参照）、アウターチューブ２３がインナーコア１３の逃げ場を作ることから、インナーコア１３の座屈変形を防止することができる。
【００５０】
尚、本発明は、容体内レリースワイヤ配線タイプの排水栓装置を詳述しているが、請求項１、３、４においては容体外レリースワイヤ配線タイプの排水栓装置を包含するものである。
即ち、通常容体外レリース配線タイプの排水栓装置は、浴槽であればその上縁面に、また洗面器であればボール部サイドの上縁面等に各々操作部が取付けられる。詳細には、その操作部は、円筒状の押し釦ケースから取付鍔部を突設し、その取付鍔部を上縁面やその上縁面に設けた凹部に収容状に取付け、その押し釦ケースに上下動可能に嵌挿された軸の先端に押し釦には取付けてあり、一方排水栓は、浴槽の底に開口されている排水口に設けられた排水口部材に、操作部（詳細には押し釦）の押動操作によるインナーコアの前進で支軸を上昇させて栓蓋を持上げロックして開栓し次のインナーコアの前進でそのロックを解除して栓蓋を下降させて閉栓するスラストロック機構を内蔵したメカボックスを備えた周知な構造になっている。
前記レリースワイヤの一端側を操作部に前記第１、第２、第３の実施の形態と同様な構成でもって連結し、レリースワイヤの他端側においては前記周知な構造でメカボックスの底部に連結しインナーコアのみをメカボックス内に位置する支軸を昇降できるように挿通させるようにする。
このようにすることよって、容体外レリース配線タイプの排水栓装置であっても、増し締めを伴うジョイント金具の螺子込み作業が全く不要であり、操作部（詳細には押し釦ケース）へのレリースワイヤの組付作業が非常に簡単な排水栓装置を構成することができるものであるし、前記と同様な原因でのインナーコアの座屈変形を防止することができる。また、その容体外レリース配線タイプの排水栓装置の場合には、前記環状のシール部材は敢えて必要ではない。その場合に、前記リング状部材５の下端、圧縮弾機Ｂの下端は止め部材７上のワッシャー部材４または止め部材７で直接支持する構造を採用する。
【００５１】
【発明の効果】
本発明は以上のように、押し釦ケースに凹設されている凹窪部底に同凹窪部開放部から挿入するワッシャー部材を当接させ、続いてリング状部材を外嵌状に有するレリースワイヤの一端側をその凹窪部開放部から挿入し、最後に押し釦ケースの側部に開孔してある差込孔から止め部材を差し込み係止することで、レリースワイヤの操作部（詳細には押し釦ケース）への連結作業が完了する。
従って、従来のように増し締めを伴うジョイント金具の螺子込み作業が全く不要であり、操作部（詳細には押し釦ケース）へのレリースワイヤの組付作業が非常に簡単に行える。
しかも、従来のようにジョイント金具のような金属部材が押し釦ケースの下端から露出することがないから、例えば浴槽内にレリースワイヤを配線するタイプの排水栓装置のようにその露出する金属金具で入浴者が怪我をすることもなく、安全である。
【００５２】
また、止め部材とリング状部材との間に環状のシール材を介在して凹窪部とアウターチューブとの間を閉塞しているものにあっては、容体内レリースワイヤ配線タイプの排水栓装置において、仮に操作部の一部が浸っても水が凹窪部からインナーコアを伝ってレリースワイヤ内に進入することがなく、インナーコアの摺動性を損なわず、作動不良を回避することができる。
【００５３】
更に、特に容体内レリースワイヤ配線タイプの排水栓装置において、アウターチューブの抜けを防止するリング状部材において、アウターチューブの鍔部に当接もしくは接近する端部が鋭利状を呈していると、例えば使用中（入浴中、洗面器や流しを使用中）に誤ってレリースワイヤに手、指等が触れて引張り力が作用してもその鋭利な端部がアウターチューブの鍔部に食込んで抜けをより確実に防止する上で有効である。
【００５４】
また、ワッシャー部材がアウターチューブの鍔部の外面と凹窪部内面との空間を閉塞する振れ防止用の有底筒状を呈しているものにあっては、閉栓状態で踏みつける等して栓蓋に押圧力が掛かっている状態で押し釦を誤って押動操作するアクシデント時でも逃げ場を無くしてインナーコアの座屈変形を防止することができる。
【００５５】
そして、操作部において、レリースワイヤにおけるアウターチューブ一端に形成された鍔部を凹窪部底に当て付けられたワッシャー部材に当接すると共にそのワッシャー部材に対して前記鍔部を挟んでアウターチューブに外嵌挿されるバネ受け部材と、前記凹窪部に連通して押し釦ケースの側部に開孔された差込孔からレリースワイヤを避けて差し込まれて同凹窪部に係止する止め部材とに亘って圧縮弾機を介在している構成にあっては、前記と同様に閉栓状態で踏みつける等して栓蓋に押圧力が掛かっている状態で押し釦を誤って押動操作するアクシデント時にその圧縮弾機を圧縮してアウターチューブ端部間を接近させてインナーコアが逃げる余裕を自ずと作り出すので、アウターチューブに負担を掛けることなくインナーコアの座屈変形を防止することができるし、アウターチューブの弾性変形による反発力をインナーワイヤに掛けることも極力防止し、インナーワイヤにとっても親切設計である。
【００５６】
また、容体内レリースワイヤ配線タイプの排水栓装置において、押し釦ケースが容体の内壁部に設けられるベース板に取り付けられ、前記差込孔がベース板に相対して開孔されていると、止め部材さえもベース板で隠されて容体内に露出しないため、入浴者に対する安全性を更に向上させることができる。
【００５７】
しかも、容体内レリースワイヤ配線タイプの排水栓装置において、押し釦を押動操作してインナーコアを前進させてインナーコア他端を支軸に形成されている凹部底に突き当てて昇降体と共に栓蓋を持上げてスラストロック機構をロックして開栓し、次の押し釦の押動操作によるインナーコアの前進でスラストロック機構のロックを解除して閉栓する構造のものにあって、例えば浴槽では清掃後給水する際に押し釦を押動操作してロックを解除した後に滑って押し釦を押っぱなしのまま足で栓蓋を踏みつけた場合や、子供が槽内で遊んでいる最中に手による押し釦の押動と栓蓋に掛かる人体荷重の相互作用がほぼ同時に行なわれてインナーコアに押圧力が作用するアクシデントが生じても、インナーコアの外方への逃げを案内筒で阻止して座屈変形を防止する安全性を付与する。
【００５８】
その上、栓蓋もしくは昇降体から昇降体内に向けて垂設するインナーコアの案内筒が支軸に凹設した凹部内に遊嵌もしくは摺動する構成であるから、開栓する時及び閉栓する時昇降体が支軸の挿通部を中心にグラ付くことがなく優れた直進性を発揮し、スラストロック機構を構成する歯の噛み合い関係が不良になって空作動するようなアクシデントも未然に防止することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a drain plug device, and more particularly, a drain plug having a thrust lock mechanism as an operating unit that opens and closes a drain plug by alternately repeating locking and unlocking each time a push button of an operation unit is pushed. It concerns the device.
[0002]
[Prior art]
Conventionally, Japanese Unexamined Patent Publication No. 8-177100 (the former) exists as a drain plug device.
In this prior art, as shown in FIG. 13, a flange 231 is provided around the end of the outer tube 23 of the release wire 3, and the flange 231 is connected to the opposite end of the joint fitting 9 on the opposite side from the push button case 21 side. The rotation guide ring member 10 that fits loosely into the outer tube 23 is interposed between the flange portion 231 and the outer peripheral surface of the outer tube 23 in the accommodation recess 19 formed in the accommodation recess 19. An operating unit 1 in which the metal fitting 9 is fixed to the rotation guide ring member 10 and the end of the joint metal 9 on the push button case 21 side is screwed into a screw hole 21 ′ provided at the lower end of the push button case 21. And a connection structure between the cable and the release wire 3.
The operation unit 1 is provided below the through hole 212 in which the shaft 311 is opened in the push button case 21 with the upper end of the inner core 13 projecting upward through the joint fitting 9 connected to the shaft 311 of the push button 31. It has a structure in which it is screwed into the screw hole 21 ′ of the push button case 21 to the joint fitting 9 while being inserted upward from the open portion, and the rotation guide ring member 10 is engaged with the flange portion 231 of the outer tube 23. In a state where the joint fitting 9 is stopped and prevented from coming off, the joint fitting 9 rotates together with the joint fitting 9 irrespective of the outer tube 23 so that the joint fitting 9 can be connected to the push button case 21 without rotating the release wire 3.
The other end of the release wire is connected to an operating portion including a thrust lock mechanism provided on the drain plug.
Further, as a technique proposed by the present applicant, there is also a drain plug device of a container release wire wiring type disclosed in Japanese Patent Application No. 11-368402 (the latter).
This prior art is a container release wiring type drain plug device in which a thrust lock mechanism 52 provided on the drain plug 2 is used as an operating portion, and the drain plug is connected to a center of a drain port 101 as shown in FIG. A cylindrical guide portion 12 having a bottom and a hollow internal lifter 32 vertically suspended from the stopper 22 and guided up and down by the guide portion 12, and a vertical lifter 32 from the bottom of the lifter 32 A support shaft 42 having one end inserted into the body 32 and the other end locked to the bottom of the guide portion 12, and an inner core at the other end of the release wire 3 penetrating the stopper 22 and positioned in the elevating body 32. 13, the other end of the inner core 13 is provided between the support shaft 42 and the elevating body 32, and the other end of the inner core 13 is abutted against the bottom of the concave portion 421 formed on the support shaft 42 by advancing operation of the operation unit. Lift the stopper 22 together with the elevating body 32 and lock it. Plug and to release the lock in advance of the next inner core 13 is configured to have a thrust lock mechanism 52 for plugging.
[0003]
However, in the former case, when the release wire 3 is connected to the operation unit (specifically, the push button case) 1, the joint fitting 9 must be screwed in, and additional tightening with a tool such as pliers is also required. The work of assembling the release wire to the operation unit at the factory is very troublesome.
Further, since the joint fitting 9 is exposed from the lower end of the push button case 21, for example, in a drain plug device of a type in which a release wire is wired in a container such as a bathtub, a sink, a basin, etc., in particular, a bathtub. There is also a problem that the bather is injured by the joint fitting 9 exposed at the lower part of the bath.
Further, there is a possibility that the inner core may be buckled and deformed during an accident in which the push button is erroneously pushed in a state in which the pressing force is applied to the drain plug (plug lid) by stepping on the plug in a closed state.
In the latter case, since the inner core 13 above the support shaft 42 faces the space in the elevating body 32 in the open state as shown in FIG. 14, the push button 31 is pushed from the open state to operate. There is a problem that the inner core 13 is buckled and deformed in the space inside the elevating body 32 above the concave portion 421 due to an accident in which a load is erroneously applied to the stopper 22 while the push button 31 is kept pressed when the lock is released. Occurs (see dash-double-dot line). This problem occurs at the time of cleaning or when a child plays a prank. When such buckling deformation occurs, the replacement of the inner core 13 accompanying the disassembly of the drainage plug device is forced, and the replacement work becomes very troublesome.
[0004]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a drainage plug device in which the operation of connecting a release wire to an operation unit is simple and a metal fitting is not exposed to the outside.
Another purpose is to provide a drain plug device that does not cause the inner core to buckle even if the push button is pressed by mistake while the pressing force is applied to the plug lid by stepping on the plug in a closed state. To provide.
Still another object is to release the lock by pushing the push button from the open state in a container release wiring type drain cock device having a thrust lock mechanism as an operating part in the drain cock. An object of the present invention is to provide a drain plug device in which the inner core is not likely to buckle even if a load is applied to the plug lid by mistake while the push button is not pressed.
[0005]
[Means for Solving the Problems]
The technical means taken to solve the above-mentioned object is to open and close the drain cock by a pushing operation of an operating part connected via a release wire to a drain cock provided in a container such as a bathtub, a sink, a basin or the like. In the drain plug device, the one end side of the release wire is inserted into the recessed portion recessed from the side opposite to the push button side of the push button case in the operation section, and the inner core projecting from the release wire is pushed with the push button. Pushable, and a flange formed at one end of the outer tube of the release wire abuts against a washer member applied to the bottom of the recessed portion, and is provided on the outer tube so as to fit externally, and one end of the release tube is attached to the flange. The other end of the ring-shaped member which is in contact with or close to the recess is inserted into the insertion hole opened to the side of the push button case while communicating with the depression, avoiding the release wire and locked in the depression. Stop In which it characterized in that it is directly or indirectly supported (claim 1).
The stop member has an open portion that does not interfere with the release wire at the time of insertion, and is formed in a plan view shape with the front side opened. A locking recess is formed on the inner surface of the recessed portion to be locked by a stopper member to be inserted.
The term "indirectly supporting" means supporting via an intervening member, and an example of the intervening member includes an O-ring that closes a gap between the concave portion and the outer tube in a watertight manner.
The stop member is formed of a synthetic resin material such as POM.
[0006]
According to the above technical means, the washer is inserted into the recess of the push button case from the opening of the recess, and then the ring-shaped member is released. One end of the wire is inserted from the recessed opening, and then the ring-shaped member is inserted into the insertion hole opened on the side of the push button case and locked by the recessed portion. To support.
As a result, the flange portion at one end of the outer tube of the release wire is supported so as not to come off by the washer member and the ring-shaped member supported by the stopper member, and the inner core protruding from the outer tube is vertically movable to the push button case. It can be pushed by the axis of the push button to be inserted.
Therefore, the operation part of the release wire (e.g., a simple operation of inserting one end side of the release wire provided with the washer member and the ring-shaped member in the form of an external fitting from the opening portion of the concave portion and inserting the stopper member from the side, Specifically, the connection work to the push button case is completed.
[0007]
Further, the drain plug is opened and closed by a pushing operation of an operation unit connected to a drain plug provided on a container such as a bathtub, a sink, a basin via a release wire, and the operation unit is provided on an inner wall surface of the container. In the drain plug device, one end of a release wire is inserted into a recessed portion recessed from the side opposite to the push button side of the push button case in the operation section, and the inner core projecting from the release wire is pushed with a push button. Pushable, and a flange formed at one end of the outer tube of the release wire abuts against a washer member applied to the bottom of the recessed portion. The other end of the ring-shaped member that is in contact with or close to the recess is inserted into the insertion hole opened to the side of the push button case while communicating with the depression, avoiding the inner core, and locked in the depression. Indirect with stop member It is also effective when the means for supporting and indirectly supporting is an annular seal member interposed between the stopper member and the ring-shaped member and closing the gap between the concave portion and the outer tube. (Claim 2).
An O-ring is an example of this annular seal member.
[0008]
According to the above technical means, the release wire can be connected to the operation unit (specifically, the push button case) by the same simple operation as in claim 1, even though the drainage plug device is of the release wire wiring type in the container. In addition, intrusion of water from the concave portion into the inner core is prevented by the annular seal member closing the concave portion.
[0009]
Further, it is preferable that the one end of the ring-shaped member is formed in a sharp shape that abuts on or approaches the flange of the outer tube (claim 3).
[0010]
According to the above-mentioned technical means, the outer tube is pierced into the flange in the pulling direction of the outer tube so as to enhance the pull-out strength of the outer tube.
[0011]
Further, irrespective of the inside-body release wire wiring type and the outside-body release wire wiring type, the washer member closes the space between the outer surface of the outer tube flange portion and the inner surface of the recessed portion, and is inserted into the recessed portion and inserted into the recessed portion. It is more preferable that the end portion has a cylindrical shape with a bottom fitted therein (claim 4).
[0012]
According to the technical means, the washer member, one end side of the release wire into which the ring-shaped member is externally inserted is required to be sequentially inserted from the open portion of the concave portion. A space (clearance) is generated between them. Due to the space (clearance), if you push the push button by mistake while pressing on the stopper by pressing the stopper, etc. in the closed state, the inner core that loses the escape place without pushing up the stopper, It escapes and bends in the space (clearance) and causes buckling deformation at that portion. Escape areas that cause the buckling deformation are eliminated by a bottomed cylindrical washer member that closes the space (clearance) between the flange portion of the outer tube and the inner surface of the concave portion.
At that time, a compressive force acts on the inner core.If the inner core is a coil made of a metal material, the inner core responds by compressing it. Respond with elastic distraction.
[0013]
Further, in a drain plug device that opens and closes the drain plug by a pushing operation of an operation unit connected to a drain plug provided on a container such as a bathtub, a sink, and a basin via a release wire, the push button in the operation unit One end of the release wire is inserted into the recessed portion that is recessed from the side opposite to the push button side of the case, and the inner core protruding from the release wire can be pushed by the push button, and the inner core protruding from the release wire is attached to one end of the outer tube of the release wire. A spring receiving member is provided which abuts the formed flange portion on a washer member applied to the bottom of the recessed portion and which is externally fitted to the outer tube with the flange portion interposed between the washer member and the spring receiving member. And a stop member which is inserted into the insertion hole formed in the side portion of the push button case in communication with the recessed portion and which is inserted around the release wire to avoid the release wire and latches in the recessed portion. It is effective even if intervening bullet machine (claim 5).
[0014]
According to this technical means, the washer member inserted from the concave recess opening portion is brought into contact with the bottom of the concave recess formed in the push button case, and the spring receiving member and the compression elastic machine are externally inserted. In this state, insert one end of the release wire from the recessed portion opening, and then insert the release wire through the insertion hole opened in the side of the push button case with a stopper member that is locked in the recessed portion. The end of the compression ram that is opposite to the flange is supported.
As a result, the flange portion at one end of the outer tube of the release wire is supported so as not to come off by the stopper member and the spring receiving member receiving the elastic force of the compression ram, and the inner core protruding from the outer tube is vertically moved by the push button case. The push button can be pushed by the axis of the push button movably inserted.
Therefore, one end of the release wire, in which the washer member, the spring receiving member, and the compression spring are externally inserted, is sequentially inserted from the opening of the concave portion, and the stopper member is inserted from the side. The connection work to the section (specifically, the push button case) is completed.
Also, if you push the push button by mistake while pressing the lid with the pressing force, such as by stepping on the closed state, the inner tube deforms elastically due to the deformation of the inner core that loses the escape place without being able to push up the lid. High elongational stress occurs. At this time, the compression elastic machine is compressed to bring the end portions of the outer tube closer to each other, whereby the outer tube secures a relief area due to the compression of the inner core and prevents buckling deformation of the inner core.

The drain plug device is of a release wire type in which the operation unit is provided on the inner wall of the container, and the space between the concave portion and the outer tube is closed between the stopper and the compression ram. In the case where an annular seal member is provided, it is preferable to prevent water from entering the inner core from the concave portion with the annular seal member closing the concave portion as described above ( Claim 6).
[0016]
Further, in a case release wiring type in which the operation unit is provided on the inner wall of the container, a push button case is attached to a base plate provided on the inner wall of the container, and the insertion hole is opened relative to the base plate. In this case, since the stop member is hidden by the base plate, the design is safer for a bather.
[0017]
Also, in the container release wire wiring type drain plug device, the drain plug is provided with a bottomed tubular guide portion disposed at the mouth in the drain port, and is vertically suspended from the plug lid and can move up and down to the guide portion. An internally hollow elevating body to be guided, a support shaft having one end inserted into the elevating body from the bottom of the elevating body and the other end locked to the bottom of the guide part, and penetrating through the plug lid into the elevating body. The inner core at the other end of the release wire and the bottom of the recess formed between the support shaft and the elevating body, the other end of the inner core being formed on the support shaft when the inner core is advanced by the pushing operation of the operation unit. A thrust lock mechanism that lifts and locks the stopper lid together with the elevating body to open and then unlocks and closes the stopper with the advance of the next inner core. Hang the inner core guide tube toward The guide tube is configured to be loosely fitted or slidably engaged with the recess of the support shaft through a slight clearance, and the guide tube is inserted into the recess in the unlocked state when the length of the guide tube is set in the unlocked state. It is also effective when the length is set to be located (claim 8).
[0018]
According to the above technical means, the push button is pushed to move the inner core forward so that the other end of the inner core abuts against the bottom of the recess formed on the support shaft, and the stopper is lifted together with the elevating member to thereby lock the thrust. The mechanism is locked and opened, and the thrust lock mechanism is unlocked and closed by the advance of the inner core by the pushing operation of the next push button.
When the push button is pushed from the open state and the lock is released, the push button is pushed down and accidentally stepped on while holding down the push button. Escape is prevented by the guide tube, and buckling deformation of the inner core is prevented. Although there is no buckling deformation, a compressive force acts on the inner core, but if the inner core is a coil-shaped metal core, it will respond by its own compression, and if it is an incompressible inner core, It is the same as described above that the outer tube is elastically extended.
The condition in which the pressing force acts on the stopper by, for example, erroneously stepping on while keeping the push button pressed at the stage where the lock is released by pushing the push button from the opened state, that is, the push button side and The conditions under which the load from both the lid side is applied are, for example, in a bath tub, when the water is supplied after cleaning, the push button is pushed to release the lock, and then the lid is slid and the push button is pushed and the lid is pushed. Occurs when stepping on the button or when the interaction between the pushing operation of the push button by hand and the human body load on the stopper is performed almost simultaneously while the child is playing in the tank.

The tooth portion 521a is guided to the groove portion 32 '(FIG. 7D), and the elevating body 32 is lowered to the above-described FIG. 2 and closed (closed).
[0045]
Therefore, in the drain plug device having such a configuration, the washer members 4 and 4, the ring-shaped member 5, and the release of the seal member 6 can be released without performing a screwing operation using a special tool such as a pliers. One end side of the release wire 3 can be connected to the operation unit 1 without externally exposing the metal member to the operation unit 1 by externally fitting the wire 3 and inserting the stopper member 7.
Further, at the time of opening, since the layout is such that the distal end of the guide tube 221g of the inner core 13 is located at least in the concave portion 421 of the support shaft 42, the push button 31 is pushed from the opened state to lock. Even if an accident occurs in which the push button 31 is erroneously pushed and pressed and the stopper 22 is stepped on at the stage of release, the escape of the inner core 13 into the space inside the elevating body 32 by the guide cylinder 221g is performed. Is prevented (see FIG. 9).
[0046]
Next, a second embodiment shown in FIG. 10 will be described. In this embodiment, the upper washer member 4 is provided with a space between the outer peripheral surface of the flange 231 of the outer tube 23 and the inner surface of the concave portion 211. (Clearance) Since it is the same as the above-described first embodiment except that it has a run-out preventing tubular portion 14 formed in a bottomed tubular shape that closes S, the same reference numerals are given and the description is omitted. .
[0047]
In the above-described first embodiment, one end of the release wire 3 into which the upper and lower washer members 4 and 4 and the ring-shaped member 5 are externally inserted needs to be sequentially inserted from the open portion of the concave portion 211 and the outer tube A space (clearance) S is generated between the periphery of the flange portion 231 and the inner surface of the concave portion 211 (see FIGS. 1 and 8). If the push button 31 is erroneously pushed or pushed in a state in which the stopper lid 22 is being pressed by pressing the stopper lid 22 or the like, the inner core 13 losing the escape place escapes and bends in the space S to be bent. Buckling deformation occurs. The relief structure causing the buckling deformation is eliminated by the run-out preventing tubular portion 14 that closes the space S between the flange portion 231 of the outer tube 23 and the inner surface of the concave recess 211.
The cylindrical portion 14 is formed to have a diameter such that it can be fitted just when inserted into the concave portion 211 that connects one end of the release wire 3 to the operation portion 1.
The order in which one end of the release wire 3 is attached to the push button case 21 is the same as that in the first embodiment, and a description thereof will be omitted.
[0048]
Next, a third embodiment shown in FIGS. 11 and 12 will be described. In this embodiment, instead of omitting the ring-shaped member, the washer member 4 having the cylindrical portion 14 is used. A spring receiving member 4 ′ is provided to be externally inserted into the outer tube 23 with the flange portion 231 of the outer tube 23 interposed therebetween, and compression is performed between the spring receiving member 4 ′ and the washer member 4 immediately above the annular seal member 7. It has a structure in which a bullet B is interposed.
The spring receiving member 4 'and the washer member 4 immediately above the annular seal member 6 are both flat washers.
The compression ram B is interposed between the spring receiving member 4 ′ and the annular seal member 6 on the stopper member 7.
[0049]
In this embodiment, as shown in FIG. 11, the outer tube 231 is in elastic contact with the concave portion 211 indirectly via the washer member 4 due to the elastic repulsion of the compression elastic machine B in a normal state. When the push button 31 is erroneously pushed in a state in which a pressing force is applied to the stopper lid 22 by, for example, stepping on the stopper state, a compressive force is generated in the inner core 13. The portion 231 is lowered so as to approach the end portions so as to compress the compression ram B via the spring receiving member 4 ′ (see FIG. 12), so that the outer tube 23 creates a relief for the inner core 13. The buckling deformation of the inner core 13 can be prevented.
[0050]
Although the present invention has described in detail a drain wire plug device of a release wire wiring type in a container, claims 1, 3, and 4 include a drain plug device of a release wire wiring type outside a container.
That is, the operation unit is usually attached to the upper edge surface of the bathtub or the upper edge surface of the ball part side in the case of a wash basin. In detail, the operation unit projects a mounting flange from a cylindrical push button case, and mounts the mounting flange in an upper edge surface or a concave portion provided on the upper edge surface in a housing state, and the push button is provided. A push button is attached to the tip of a shaft that is vertically movably inserted into the case, while a drain plug is attached to a drain port member provided at a drain port opened at the bottom of the bathtub by an operation unit (details). Then push the push button) to raise the spindle with the advance of the inner core, lift the stopper, lock and open it, release the lock with the next advance of the inner core, and lower the stopper. It has a well-known structure including a radio box with a built-in thrust lock mechanism for closing.
One end of the release wire is connected to the operation unit in the same configuration as in the first, second, and third embodiments, and the other end of the release wire is connected to the bottom of the radio box by the well-known structure. Only the inner core is connected so that the support shaft located in the radio box can be moved up and down.
By doing so, even in the case of a drain plug device of the extracorporeal release wiring type, the work of screwing the joint fittings together with retightening is not required at all, and the release to the operation unit (specifically, the push button case) is performed. This makes it possible to form a drain plug device in which the operation of assembling the wires is extremely simple, and it is possible to prevent buckling deformation of the inner core due to the same reason as described above. Further, in the case of the drainage plug device of the extracorporeal release wiring type, the annular sealing member is not required. In this case, a structure is employed in which the lower end of the ring-shaped member 5 and the lower end of the compression ram B are directly supported by the washer member 4 on the stopper member 7 or the stopper member 7.
[0051]
【The invention's effect】
As described above, the present invention provides a release having a recessed portion formed in a push button case, which is brought into contact with a washer member to be inserted from the recessed portion opening portion, and then a ring-shaped member is externally fitted. One end of the wire is inserted from the open portion of the concave portion, and a stop member is inserted and locked from the insertion hole finally opened on the side of the push button case, thereby operating the release wire (details). The connection work to the push button case is completed.
Therefore, the work of screwing the joint fittings together with retightening as in the related art is not required at all, and the work of assembling the release wire to the operation unit (specifically, the push button case) can be performed very easily.
Moreover, since a metal member such as a joint fitting is not exposed from the lower end of the push button case as in the related art, for example, the exposed metal fitting such as a drain plug device of a type in which a release wire is wired in a bathtub is used. The bather is safe without injury.
[0052]
Further, in a device in which an annular sealing member is interposed between the stopper member and the ring-shaped member to close the gap between the concave portion and the outer tube, a drain wire plug type drain wire plug device in a container. Even if a part of the operation part is immersed, water does not enter the release wire through the inner core from the concave part, does not impair the slidability of the inner core, and avoids malfunction. it can.
[0053]
Furthermore, in particular, in a body release wire wiring type drain plug device, in a ring-shaped member that prevents the outer tube from coming off, if the end that comes into contact with or approaches the flange portion of the outer tube has a sharp shape, for example, Even if your hand or finger touches the release wire accidentally during use (during bathing, using a basin or sink) and a tensile force is applied, the sharp end of the release wire cuts into the flange of the outer tube and comes off. Is more effective in preventing the occurrence of the problem.
[0054]
Further, in the case where the washer member has a bottomed cylindrical shape for preventing run-out which blocks the space between the outer surface of the outer tube flange and the inner surface of the concave portion, the stopper is stepped on in a closed state or the like. Thus, even in the event of an accidental push operation of the push button in a state in which the inner core is under pressure, there is no escape place and buckling deformation of the inner core can be prevented.
[0055]
Then, in the operating section, the flange formed at one end of the outer tube of the release wire is brought into contact with a washer member applied to the bottom of the concave portion, and the outer portion of the release wire is connected to the outer tube through the flange. A spring receiving member to be inserted and a stop member communicating with the recessed portion and being inserted around the release hole from the insertion hole opened in the side portion of the push button case so as to be inserted into the recessed portion and locked in the recessed portion; In the configuration in which the compression ram is interposed over, in the event of an accident in which the push button is erroneously pushed in the state in which pressing force is applied to the stopper by, for example, stepping on the stopper in the closed state as described above. By compressing the compression ram and bringing the outer tube ends closer together, the inner core naturally creates room for escape, so the buckling of the inner core is reduced without straining the outer tube. It can be prevented, also prevented as much as possible to apply a repulsive force due to elastic deformation of the outer tube to the inner cable, is also friendly design for the inner wire.
[0056]
Further, in the drainage plug device of the release wire wiring type in the container, the push button case is attached to the base plate provided on the inner wall portion of the container, and the insertion hole is opened relative to the base plate. Even the members are hidden by the base plate and are not exposed to the inside of the container, so that the safety for the bather can be further improved.
