【発明の属する技術分野】
本発明は、建物に設置する手摺の複数の手摺杆を連結すると共に連結個所で設置壁面に取付けることのできる手摺杆の取付連結装置、特に浴室等の水を多用す個所に設置して有効な手摺杆の連結兼取付装置に関する。
【０００２】
【従来の技術】
浴室等で、設置壁面上で、上下に延長する手摺杆と水平に延長する手摺杆とをＬ字状をなすように配置した手摺が近年屡々使用されるようになってきている。Ｌ字状をなす手摺を得る方法として、長い手摺杆をＬ字状に曲げ加工する方法があるが、曲げ加工の場合には加工上の制約を受けるためにその曲率半径をあまり小さくすることができないことから、手摺の把持部として特に有効な個所である直線部分の長さが制限されることになるので、手摺機能の低下に繋がる上に、曲り部で設置壁面への手摺杆固定用の取付金具を取付けることは可成り困難であって、実際的には近接する直線部において取付金具を設けることが通例であり、曲り部付近での力学的強度が十分に確保できなかったり、また取付金具によって手摺杆の直線部が占用されるために、更なる手摺機能の低下を生じることになる。
【０００３】
また２本の手摺杆をＬ字状の曲り部で連結する方法も採用されているが、現在手摺杆相互の連結と設置壁面への固定のための取付との両者を行うと共に、連結兼取付部で優れた機能と滑らかな外見とを備えた連結兼取付装置は開発されておらず、一般的には比較的無骨な外見を有する連結金具と取付金具とを用いて手摺が設置されているのが実情である。
【０００４】
【発明が解決しようとする課題】
本発明が解決しようとする課題は、曲り部ふくむ手摺杆相互の連結を行うと共に、該連結個所において設置壁面に固定するための取付を行うことができ、手摺機能を充分に発揮できると共に、外観も優美な手摺杆の連結兼取付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】
前記課題を解決するために、本発明による手摺杆の連結兼取付装置は、設置壁面に取付けられるべき取付板部から複数の手摺杆の端部を支持するための複数の支持板部が立設されたブラケット本体を有する手摺杆の連結兼取付装置において、該ブラケット本体の取付板部には取付用透孔が穿設された取付基部から複数の手摺杆におけるそれぞれの軸線方向に沿う延長部が形成され、各該支持板部は各該延長部の端部において支持すべき該手摺杆端部を挿入固定する支持凹部が凹設される外面と該外面に対向する内面を形成するように立設され、各該支持板部の内面側には各該手摺杆の軸線方向と垂直な該支持板部の外形輪郭に沿う段状面が形成され、該段状面の両側において凹窪が形成され、各側端縁部においては該ブラケット本体における各該段状面に対応する内側面と該支持板部と同形の外形輪郭とを有すると共に該ブラケット本体の該取付板部上を被覆するブラケットカバーにはその各側端縁部の両側の該内側面に係合突起が突設され、該ブラケット本体における各該段状面の両該凹窪には対応する該ブラケットカバーの各該側端縁部における両該係合突起が弾発的に係合されて該ブラケットカバーが該ブラケット本体に嵌着され、該凹窪と該係合突起との所要数の係合個所においては、該凹窪は該ブラケット本体における該段状面の内方に向けられて形成され、またこれに対応する該係合突起は該ブラケットカバーの側端縁部から内方に向けて突設されたものであることを主な特徴とする。
【０００６】
また、該手摺杆の連結兼取付装置において、ブラケット本体の設置壁面に対する取付位置を容易に確認できるようにするために、前記ブラケット本体の取付板部における取付基部外面および取付用透孔内周面の一方または双方には、少なくとも支持される前記手摺杆における軸線投影線上の位置決め用指標が付されていることを特徴とする。
【０００７】
さらに、設置壁面に対するブラケット本体のより水密性のよい取付を得るために、前記ブラケット本体の取付板部の平面外形輪郭に対応する平面外形を有し、前記取付用透孔周囲に対応する位置に取付ネジ通過開口が開設されると共に該取付ネジ通過開口に接して下向き山形状縁が周回されている水密性柔軟材料製の座板を前記設置壁面と該ブラケット本体の該取付板部との間に介在させて取付けられることを特徴とする。
【０００８】
【発明の実施の形態】
本発明の実施の形態について添付図面を参照して説明する。図１には、上下方向および水平方向に延びる直角状をなす２本の手摺杆１，１について、それぞれの手摺杆１，１が端部で連結されると共に該連結部分で設置壁面２となるタイル壁面に取付けられるようにされた本発明にかかる連結兼取付装置５の例についてその設置状況が示されている。図中符号３はタイル壁面の目地を示し、また符号４は２本の手摺杆１，１の非連結側で、手摺杆１，１のそれぞれの端部を支持固定して設置壁面２に取付ける端部ブラケットを示す。連結兼取付装置５は、手摺を支持することのできる建物の任意の個所の設置壁面２に設置して使用することができるが、特に水を多用する浴室、洗面所、ユティリティルーム、厨房等に設置して使用する場合に有効である。
【０００９】
手摺杆１，１のそれぞれの端部を連結状に支持固定すると共に設置壁面２に取付けるために、連結兼取付装置５には、ブラケット本体１０が設けられている。ブラケット本体１０は、例えばＡＢＳ樹脂のような弾性を有する合成樹脂により成形される。図２、図３および図４で明らかなように、ブラケット本体１０には、設置壁面２に取付けられる取付板部１１が形成されている。取付板部１１は、設置壁面２に対して締着される取付ネジを挿通するための取付用透孔１２，１２，１２が穿設された取付基部１３と取付基部１３から直角に配置された手摺杆１，１のそれぞれの軸線方向に沿って延びる延長部１４，１４により構成され、したがって取付板部１１はＬ字状をなす平面外形を有する。取付板部１１の延長部１４，１４の端部にはその外面に手摺杆１，１の端部を挿入固定するための支持凹部１５，１５を備えた支持板部１６，１６が立設され、支持板部１６の外面に対向する内面側には手摺杆１，１のそれぞれ軸線方向と垂直な支持板部１６，１６の外形輪郭に沿う段状面１７，１７が形成されている。
【００１０】
取付板部１１と支持板部１６，１６との間には、両者を接合して補強する出隅側および入隅側の壁部が形成されている。即ち出隅側にはその外面が段状面１７，１７と面一とされると共にそれぞれの支持板部１６，１６と取付板部１１とが接合される出隅側壁部１８，１８が、また入隅側にはその外面が支持板部１６，１６の外周輪郭と面一とされると共に取付板部１１と両支持板部１６，１６とが接合される入隅側壁部１９が形成されている。入隅側壁部１９にはその頂面２０に沿って凹入溝２１が形成されており、凹入溝２１の端部内側面は段状面１７と同一面とされ、段状面１７，１７の位置における凹入溝２１は後述する一方の凹窪２２を形成する。また各支持板部１６の凹窪２２の位置に対向する出隅側の段状面１７には、後述する他方の凹窪２３が段状面１７から内方に向けて凹入するように形成されている。取付板部１１における略正方形状の３個の取付用透孔１２，１２，１２は、Ｌ字状をなすように穿設され、手摺杆１，１端部に近接する取付用透孔１２の内周面には、位置決め用指標２４となる厚さ方向の溝が設けられている。
【００１１】
各取付用透孔１２の位置決め用指標２４は、各手摺杆１における軸線投影線上に位置するものと、この投影線と垂直な線上に位置するものとの２種類が付される。また取付板部１１の外側面にも、各手摺杆１における軸線投影線上に位置する個所か、または各手摺杆１における軸線投影線に直交し且つ取付用透孔１２に付されたこの投影線に垂直な位置決め用指標２４を通る直線が取付板部１１の外側面と交差する個所において位置決め用指標２５となる厚さ方向の溝が設けられている。さらに取付板部１１には後述するブラケットカバー３５の係合を案内し且つその係合状態を補強する目的で内側壁部１９に近接して先端部が先細にされた嵌合用軸２６が立設されている。また取付板部１１裏面には、図３に示されるように、取付用透孔１２，１２，１２の回りを囲む浅い周回状凹陥部３４が形成されている。
【００１２】
図５に示されるように、支持板部１６は厚肉に形成され、支持凹部１５は、支持板部１６の外面から厚みの奥深い内壁２７に至る迄形成された円孔と、内壁２７から支持板部１６の外面を超えて突出する環状突起２８との間隙で形成される。また支持凹部１５の下側部には支持凹部１５に向って取付板部１１側から連通孔２９が穿孔されている。本発明で使用される手摺杆１は、ステンレス鋼管のような鋼管３０に、軟質、半硬質、或は硬質の合成樹脂被覆層３１を被覆成形した合成樹脂被覆鋼管が使用され、特に好ましくは、その合成樹脂被覆層３１の外表面に手摺杆１の長手方向に沿う把持用凹部が間隔をおいて列設された被覆鋼管が使用される。そして手摺杆１の先端部分における合成樹脂被覆層３１は、支持板部１６の支持凹部１５に挿入できるように、所定位置から先端にかけて支持凹部１５の形状に相当する太さに表面側を皮剥き加工して縮径した被覆層とされる。また先端部分には固定ネジ３３を通過させるための通孔３２が穿設される。
【００１３】
手摺杆１を支持板部１６に固定する場合に、縮径加工された手摺杆１の先端部を支持凹部１５に挿入すると、手摺杆１における鋼管３０内周が環状突起２８に接触することにより鋼管３０は容易に抜出さないように支持される。そして連通孔２９を通じて、固定ネジ３３を手摺杆１先端に穿孔された通孔３２を通過させて環状突起２８に螺着すると手摺杆２は支持板部１６に完全に固定される。この状態で、手摺杆２における合成樹脂被覆層３１の表面は、支持板部１６の外形輪郭内に収容されるか、または外形輪郭と外周部では同一面を形成するように取付けられる。なお図５中、符号６はブラケット本体１０を設置壁面２上に取付けるために取付板部１１の取付用透孔１２から設置壁面２に対して締付けられた取付ネジを示し、また符号７は取付ネジ６が挿通される座金を示す。
【００１４】
ブラケット本体１０を被覆するブラケットカバー３５は、例えばＡＢＳ樹脂のような弾力性を有する硬質合成樹脂や金属によって成形され、図２および図３に示されるように、各側端縁部３６，３６においてはブラケット本体１０の支持板部１６における段状面１７に対応する内側面を有すると共に支持板部１６と同形の外形輪郭を有し、出隅側壁部１８，１８を含む出隅側から入隅側壁部１９の頂面２０にかけて取付板部１１上を被覆する形状とされる。したがってブラケット本体１０にブラケットカバー３５が被覆された場合に、その出隅側下縁３７はブラケット本体１０の取付板部１１下面に対応する位置に達し、またその入隅側下縁３８は入隅側壁部１９の頂面２０に当接する位置に達する。そして側端縁部３６，３６において前記支持板部１６の段状面１７における一方の凹窪２２に対応する位置の内側面には、垂下する係合突起３９が、またこれと対向する位置の段状面１７における凹窪２３に対応する位置の内側面には、内向きの係合突起４０がそれぞれ突設されている。ブラケットカバー３５にはさらにブラケット本体１１における嵌合用軸２６の位置に対応させて嵌合用軸２６と嵌合することのできる嵌合用管軸４１が立設されている。
【００１５】
ブラケット本体１０にブラケットカバー３５を被覆装着する場合には、ブラケット本体１０の嵌合用軸２６にブラケットカバー３５の嵌合用管軸４１を嵌合させて押込むと、やがてブラケット本体１０の段状面１７にブラケットカバー３５の側端縁部３６が当接し、ブラケット本体１０における取付板部１１の出隅側周縁をブラケットカバー３５の出隅側下縁３７が内包し、ブラケット本体１０の頂面２０にブラケットカバー３５の入隅側下縁３８が当接すると同時に、ブラケットカバー３５における係合突起３９，４０がそれぞれブラケット本体１０における凹窪２２，２３に弾発的に係合される。係合突起４０は内向きに突設され、また凹窪２３は段状面１７から内方に向けて凹入するように設けられているから、被覆状態のブラケットカバー３５はブラケット本体１０から簡単に離脱することのない係止状態を得ることができる。
【００１６】
またブラケット本体１０の支持板部１６の外面輪郭とブラケットカバー３５の側端縁部３６外面とは面一に形成されるから、把持した手に抵抗を感じるような段差を生むことがなく、接続個所が目立たないスムースな外観を得ることができる。さらに係合突起３９，４０と凹窪２２，２３は、いずれも段状面１７上の位置で弾発的に係合されるから、ブラケットカバー３５はその側端縁部３６をブラケット本体１０の段状面１７上に常時維持され、ブラケットカバー３５に加わる外力を局部的な応力集中を伴うことなくブラケット本体１０に伝達することができると共に、経年の使用によってもブラケット本体１０とブラケットカバー３５との間に隙間を生じたりすることがない。
【００１７】
連結兼取付装置５を設置壁面２に設置するには、先ず連結すべき２本の手摺杆１，１について端部を前述のように皮剥き加工し、各手摺杆１の端部をブラケット本体１０の支持凹部１５に挿入固定する。この状態で２本の手摺杆１，１は連結状態となる。皮剥き加工を開始した箇所には被覆層の段部面が形成されているので、被覆層段部面をブラケット本体１０における支持板部１１の外面に密着させると、該部での水密性が確保されブラケット本体１０内部への浸水が防止できる。次に各手摺杆１，１の反対側の端部をそれぞれ端部ブラケット４，４に取付ることによって連結された手摺の組立体が完成する。かかる組立体について、取付用透孔１２に付された位置決め用指標２４や取付板部１１の外側面上に付された位置決め用指標２５を利用して連結兼取付装置５の設置壁面２上の設置位置を設定する。
【００１８】
例えば設置壁面２が縦横に目地３が通るタイル面であって、目地３の交差部分に連結兼取付装置５を配置して、取付ネジ６はすべて目地３上に配置することにより、タイル上に穿孔することを防止したい場合には、上下方向に延びる手摺杆に関しては、上下方向の手摺杆１が固定された支持板部１６についての軸線投影線上に付された位置決め用指標２４，２５を上下方向に通る目地位置に合わせると共に、水平方向に延びる手摺杆に関しては、水平方向の手摺杆１が固定された支持板部１６についての軸線投影線上に付された位置決め用指標２４，２５を水平方向に通る目地位置に合わせると、取付用透孔１２，１２，１２の中心は、いずれもがタイルの上下方向目地上、水平方向目地上および上下方向目地と水平方向目地との交点上に位置することになり、この状態で取付ネジ６を締着すれば、すべての取付ネジ６はタイルの目地上に位置し、タイル上に穿孔することなく連結兼取付装置５を設置壁面２に取付けることが可能である。
【００１９】
取付ネジ６は必ずしも取付用透孔１２，１２，１２のすべてに挿入締付けを行う必要はなく、所要数の挿入締付けで足りる。なお位置決め用指標２４，２５を設置壁面２上の通常の罫書線に合致させて連結兼取付装置５の位置決めができることは云うまでもない。総じて位置決め用指標２４，２５を利用することによって連結兼取付装置５の取付作業を迅速且つ正確に行うことができるので設置作業の能率を上げることができる。連結兼取付装置５の取付に次いで端部ブラケット４，４の取付を行って手摺の設置作業を終了する。設置壁面２がタイル面の場合に、端部ブラケット４，４についても手摺杆１，１の軸線投影線上にその取付ネジ孔が存在する端部ブラケットを使用すれば、締着されるすべての取付ネジをタイルの目地上に配置することができる。
【００２０】
ブラケット本体１０は、直接設置壁面２に取付けることも可能であるが、図３に示されるような座板４５を介在させて取付けることにより、取付部の水密性を向上させることができる。座板４５は水密性の柔軟材料、例えばゴム或は柔軟な合成樹脂材料により成形され、図６および図７にその詳細が示されるように、その平面はブラケット本体１０における取付板部１１側の平面外形輪郭に相当する平面外形を有し、ブラケット本体１０の連通孔２９に密嵌する上向き突出部４６が突設され、また取付板部１１の周回状凹陥部３４に対応する形状を有すると共に周回する頂縁４７を下方に突出する山形条４８が周設された取付ネジ通過開口４９が開設されている。この座板４０は、ブラケット本体１０の設置壁面２への取付に先立って、上向き突出部４６，４６をブラケット本体１０の連通孔２９に密嵌させることによって仮着しておく。
【００２１】
座板４５を仮着したブラケット本体１０は取付壁面２の所定箇所に取付ネジ６によって取付けられるが、締着時に取付ネジ６が取付ネジ通過開口４９を通過して設置壁面２に捻込まれ、取付ブラケット１０と設置壁面２とによって押圧された山形条４８は、取付ネジ通過開口４９を外方から水密に隔離するように変形した状態でブラケット本体１０の凹陥部３４内に収容される。したがって取付ブラケット本体１０と設置壁面２との間隙から水が侵入して取付ネジ６の箇所から設置壁面２の内部に浸水することを極力防止することができる。また取付ブラケット１０の連通孔２９に密嵌した上向き突出部４６はブラケット本体１０と設置壁面２との間隙から侵入した水が手摺杆１の固定支持部に浸水することを防止する機能を有する。
【００２２】
前記した実施の形態は、２本の手摺杆１，１が直角状に配設される連結兼取付装置５についてのものであるが、図８に示されるように２本の手摺杆１，１が直線状に配設される連結兼取付装置８や、図９に示されるように３本の手摺杆１，１，１がＴ字状に配設される連結兼取付装置９も本発明の実施の形態に含まれる。これらの実施の態様において、ブラケット本体の段状面におけるブラケットカバーの係合は、入隅側では前記した連結兼取付装置５の入隅側の係合個所と同様であり、また直線状側では前記した連結兼取付装置５の出隅側の係合個所と同様に構成される。
【００２３】
【発明の効果】
本発明は次のような効果を奏する。
Ａ．手摺杆の連結すると共に連結部において設置壁面に取付けることができるから、連結具と取付具とを別体に設置する場合に比較して強度的に優れ、外観上も簡素で優美である。
Ｂ．手摺杆の連結と連結部における設置壁面への取付を同一個所で纏めて行うので、連結具や取付具を別々に設置する必要がなく、連結および取付の作業を能率良く行うことができる。
Ｃ．必要に応じて、合成樹脂被覆層を有する手摺杆において連結すべき端部付近の皮剥ぎ作業を行うほかに前処理作業は不必要であり、連結および取付作業は高度の技術を必要としないで迅速に行うことができる。
【００２４】
Ｄ．ブラケット本体における取付ネジ等はブラケットカバーで被覆され、またブラケット本体とブラケットカバーとの接続面は面一とされるので、取付ネジ頭が露出することなく、把持した手に抵抗を感じるような段差を生じるようなことがなく、接続個所が目立たないスムースな外観を得ることができる。
Ｅ．ブラケットカバーの係合突起はブラケット本体の段状面において凹窪に弾発的に係合されるから、ブラケットカバーの側端縁部はブラケット本体の段状面上に常時維持され、ブラケットカバーに加わる外力を局部的な応力集中を伴うことなくブラケット本体に伝達することができると共に、経年の使用によってもブラケット本体とブラケットカバーとの間に隙間を生じたりすることがない。
Ｆ．ブラケットカバーにおける一方の係合突起は内向きに突設され、またこの係合突起に対応するブラケット本体の凹窪は段状面から内方に向けて凹入するように設けられているから、被覆状態のブラケットカバーはブラケット本体から簡単に離脱することのない係止状態を得ることができる。
【００２５】
Ｇ．ブラケット本体の取付用透孔に付された位置決め用指標や取付板部の外側面上に付された位置決め用指標を利用して連結兼取付装置の設置壁面上の位置決めを行うことにより、設置壁面のタイル目地上にすべての取付ネジを配置するなどの位置決め操作を迅速且つ正確に行うことができるので設置作業の能率を上げることができる。
Ｈ．ブラケット本体を座板を介在させて設置壁面に取付けることにより、取付部の水密性を向上させることができる。
Ｉ．Ｌ字形やＴ字形等の曲り部や分岐部を有する手摺の場合には、手摺杆の曲げ加工や溶接接続加工等が不要であり、また曲り部や分岐部で確実に設置壁面に取付固定されるので、手摺杆の途中に別途取付具を設置する必要がなく、曲り部および分岐部における曲率半径を小さくできるので手摺杆の有効長さである手摺杆の直線部の長さを大きくすることができる。
Ｊ．手摺杆連結のためのブラケット本体への挿入固定は、ブラケット本体の底面側から行うために固定ネジが表面に露出せず、ビス頭や部材端部等で手摺を把持した手を傷つけたりしない。

TECHNICAL FIELD OF THE INVENTION
INDUSTRIAL APPLICABILITY The present invention is effective in connecting a plurality of handrails of a handrail to be installed in a building and installing and connecting a handrail to an installation wall, which can be attached to an installation wall at a connection point, particularly, in a location where water is frequently used such as a bathroom. The present invention relates to a device for connecting and attaching a handrail.
[0002]
[Prior art]
In a bathroom or the like, a handrail in which a vertically extending handrail rod and a horizontally extending handrail rod are arranged in an L-shape on an installation wall has been frequently used in recent years. As a method of obtaining an L-shaped handrail, there is a method of bending a long handrail rod into an L-shape. In the case of bending, however, the radius of curvature of the handrail is required to be too small due to processing restrictions. Since it is not possible to do so, the length of the linear portion, which is particularly effective as a handrail gripping portion, is limited, leading to a decrease in the handrail function, and a bent portion for fixing the handrail rod to the installation wall surface. It is quite difficult to attach the mounting bracket, and in practice, it is customary to provide the mounting bracket in the close straight section, and it is not possible to secure sufficient mechanical strength near the bend, or Since the linear portion of the handrail rod is occupied by the metal fitting, the handrail function is further reduced.
[0003]
Although a method of connecting two handrails by an L-shaped bent portion is also adopted, both the connection between the current handrails and the mounting for fixing to the installation wall are performed, and the connection and mounting are performed. A connecting and mounting device having excellent functions and a smooth appearance in the part has not been developed, and generally a handrail is installed using a connecting bracket and a mounting bracket having a relatively rugged appearance. That is the fact.
[0004]
[Problems to be solved by the invention]
The problem to be solved by the present invention is that the handrail rods including the bent portion can be connected to each other, and the connection point can be attached for fixing to the installation wall surface. Another object of the present invention is to provide an elegant handrail connecting and mounting device.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a handrail connecting / attaching device according to the present invention has a plurality of supporting plate portions for supporting end portions of a plurality of handrail bars from an attachment plate portion to be attached to an installation wall surface. In the device for connecting and attaching a handrail having a bracket body, a mounting plate portion of the bracket body has an extension extending along an axial direction of each of a plurality of handrails from a mounting base having a through hole for mounting. Each of the support plate portions is formed so as to form an outer surface in which a support recess for inserting and fixing the handrail rod end to be supported at an end of each of the extension portions is formed, and an inner surface opposed to the outer surface. A stepped surface is formed on the inner surface side of each of the support plate portions along the outer contour of the support plate portion perpendicular to the axis direction of each of the handrail bars, and concave portions are formed on both sides of the stepped surface. At each side edge portion of the bracket body. A bracket cover having an inner surface corresponding to the stepped surface and an outer contour having the same shape as the support plate portion and covering the mounting plate portion of the bracket main body has an inner surface on both sides of each side edge thereof. Engagement projections are protrudingly provided on the side surfaces, and both the engagement projections at each side edge of the corresponding bracket cover are elastically engaged with both the concave portions of each stepped surface of the bracket body. The bracket cover is fitted to the bracket main body, and at a required number of engagement points between the concave recess and the engaging projection, the concave recess is formed inside the stepped surface of the bracket main body. The main feature is that the engaging projection corresponding to the engaging projection is provided inwardly from the side edge of the bracket cover.
[0006]
Further, in the handrail connecting and mounting device, in order to be able to easily confirm the mounting position of the bracket body with respect to the installation wall surface, a mounting base outer surface and a mounting through-hole inner peripheral surface of the mounting plate portion of the bracket body are provided. One or both of them are provided with a positioning index on at least an axis projection line of the supported handrail bar.
[0007]
Furthermore, in order to obtain a more watertight attachment of the bracket body to the installation wall surface, the bracket body has a planar outer shape corresponding to the planar outer contour of the mounting plate portion of the bracket body, and is provided at a position corresponding to the periphery of the mounting through hole. A seat plate made of a water-tight flexible material having a mounting screw passage opening and having a downwardly ridged edge in contact with the mounting screw passage opening is provided between the installation wall surface and the mounting plate portion of the bracket body. It is characterized in that it can be attached with being interposed.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the accompanying drawings. In FIG. 1, two perpendicular rails 1, 1 extending in the vertical direction and the horizontal direction are connected at their ends, and the connecting portions form the installation wall surface 2 at the ends. An installation state of an example of the connection and attachment device 5 according to the present invention, which is adapted to be attached to a tile wall surface, is shown. In the figure, reference numeral 3 denotes a joint of the wall surface of the tile, and reference numeral 4 denotes a non-connection side of the two handrail bars 1, 1 and supports and fixes the respective ends of the handrail bars 1, 1 to the installation wall surface 2. 3 shows an end bracket. The connection and mounting device 5 can be installed and used on the installation wall 2 at any place in a building that can support handrails, and is particularly used in bathrooms, washrooms, utility rooms, kitchens and the like that use a lot of water. It is effective when installed and used.
[0009]
In order to support and fix each end of the handrail rods 1 and 1 in a connected manner and to attach them to the installation wall 2, a bracket body 10 is provided in the connecting and attaching device 5. The bracket body 10 is formed of an elastic synthetic resin such as an ABS resin, for example. As is clear from FIGS. 2, 3, and 4, the bracket main body 10 is formed with an attachment plate 11 that is attached to the installation wall surface 2. The mounting plate portion 11 is disposed at a right angle from the mounting base portion 13, in which mounting through holes 12, 12, 12 for inserting mounting screws fastened to the installation wall surface 2 are formed. Each of the handrail bars 1 and 1 is constituted by an extension portion 14 extending along the axial direction of the handrail bar 1. Therefore, the mounting plate portion 11 has an L-shaped planar outer shape.
