Description

【０００１】
【発明の属する技術分野】
この発明は、もたれ用手摺に関するものであって、更に詳細には、例えばキッチン又は洗面台等のカウンタに取り付けられている把持又はもたれかかることが可能なもたれ用手摺に関するものである。
【０００２】
【従来の技術】
例えば、キッチン又は洗面台等のキャビネットのカウンタ（取付基体）に手摺を取り付ける場合には、手摺杆とカウンタの取付面例えば幕板との間に隙間を設け、ねじ等の固定手段によって取り付けている。
【０００３】
従来、この種の手摺の取付構造としては、例えば特開平８−３７５号公報や特開平８−３８０号公報に開示されているものが知られている。
【０００４】
特開平８−３７５号公報に開示されている手摺の取付構造は、キャビネットの幕板に切欠きを形成し、幕板の裏面側に支持アームの固定片を固着させ、支持アームの支柱を幕板の切欠きに嵌め込むと共に、キャビネットの手前上方に支持アームを立設させ、支持アームの上端の支持片に手摺バーを水平に取り付ける構造である。
【０００５】
このように構成される手摺の取付構造によれば、幕板の裏面側に支持アームの固定片を固着させ、幕板に形成された切欠きから支持アームの支柱を外方に突出するので、幕板への支持アームの固定片が外部に露出されず美観の向上を図ることができる。
【０００６】
また、特開平８−３８０号公報に開示されている手摺の取付構造は、前面が開口する保持ケースをキャビネットの幕板に固着させ、この保持ケースに手摺バーに固着させた挿入具を挿入保持し、この挿入具と保持ケースとを保持ケースの下方からねじ止めして固定することにより、手摺をカウンタに取り付ける構造である。
【０００７】
このように構成される手摺の取付構造によれば、幕板と手摺との間に保持ケースを介在することによって、幕板と手摺の間に間隔を設け、保持ケースと挿入具の取付けを保持ケースの下方からねじ止めすることができるので、手摺の取付作業を容易にすることができる。
【０００８】
【発明が解決しようとする課題】
しかしながら、前者すなわち特開平８−３７５号公報に記載の手摺の取付構造においては、幕板に切欠きを形成し、幕板の裏面側に支持アームの固定片を固着させる構造であるため、幕板への切欠きを形成するための加工が必要であり、手摺の取付作業に手間がかかるという問題があった。
【０００９】
また、後者すなわち特開平８−３８０号公報に記載の手摺の取付構造においては、幕板に取り付けられた保持ケース内に挿入具を挿入して、下方からねじ止めする構造であるため、保持ケースと挿入具の寸法誤差により、保持ケースと挿入具との当接面に隙間が生じるおそれがあり、また、保持ケースの下方からねじ止めを行うことによってねじ部材が外部に露出した状態になるので、美観が損なわれるという問題があった。
【００１０】
この発明は、上記事情に鑑みなされたもので、手摺の取付作業を容易に行うと共に、取付状態の美観の向上を図るようにしたもたれ用手摺を提供することを目的とするものである。
【００１１】
【課題を解決するための手段】
上記目的を達成するために、請求項１記載の発明は、上端に把持面を有し、外側にもたれ面を有する手摺材と、取付基体に取り付けられる取付部と、この取付部から取付基体の前上方側に延在する支持部と、この支持部の先端側に設けられ、手摺杆の両端部をそれぞれ固定する固定部とを有するブラケットを具備し、上記ブラケットの取付部に、ねじ孔を有する取付座を設け、取付座を上記取付基体の表面に当接した状態で、取付基体の裏面側から挿通される取付ねじをねじ孔に螺合させて固定可能に形成し、上記手摺杆は、上端に断面円弧状の把持面を有すると共に、この把持面の外側から下方に向かって漸次外方側に緩やかに隆起する曲線状のもたれ面を有し、上記ブラケットの支持部は、上記手摺杆の把持面及びもたれ面に連続する第１の外表面を有すると共に、この第１の外表面に連続して下方及び内方に向かって曲面状に延在する第２の外表面とを有することを特徴とする。
【００１２】
このように構成することにより、取付基体に、ブラケットを取付基体の裏面側から取付固定するので、ブラケットの外方部に取付ねじの取付部等を形成する必要がなく、ブラケットの外方部に取付部等を塞ぐキャップ等を被着する必要がないので、構成部材の削減が図れると共に、ブラケットの形状を自由に形成例えばデザインすることができ、美観の向上を図ることができる。
【００１３】
請求項２記載の発明は、上端に把持面を有し、外側にもたれ面を有する手摺杆と、取付基体に取り付けられる取付体と、この取付体に取り付けられる取付部と、この取付部から取付基体の前上方側に延在する支持部と、この支持部の先端側に設けられ、手摺杆の両端部をそれぞれ固定する固定部とを有するブラケットを具備し、上記ブラケットの取付部に、ねじ孔を有する取付座を設け、上記取付体の裏面に、上記取付基体の取付部に突設された係止受部に係合する係止金具を装着し、上記ブラケットの取付座を上記取付体の表面に当接した状態で、取付体の裏面側から挿通される取付ねじをねじ孔に螺合させて固定し、上記取付体の係止金具を上記取付基体の係止受部に係止させた状態で、取付基体の裏面から挿通される取付ねじを取付体に螺着させて固定可能に形成し、上記手摺杆は、上端に断面円弧状の把持面を有すると共に、この把持面の外側から下方に向かって漸次外方側に緩やかに隆起する曲線状のもたれ面を有し、上記ブラケットの支持部は、上記手摺杆の把持面及びもたれ面に連続する第１の外表面を有すると共に、この第１の外表面に連続して下方及び内方に向かって曲面状に延在する第２の外表面とを有することを特徴とする。
【００１４】
このように構成することにより、取付体に、ブラケットを取付体の裏面から取付固定するので、ブラケットの外方部に取付ねじの取付部等を形成する必要がなく、ブラケットの外方部に取付部等を塞ぐキャップ等を被着する必要がないので、構成部材の削減が図れると共に、ブラケットの形状を自由に形成例えばデザインすることができ、美観の向上を図ることができる。また、取付体の裏面に装着された係止金具を、取付基体に設けられた係止受部に係止させた状態で、取付基体の裏面側から挿通される取付ねじを取付体に螺着させて固定することにより、手摺の取付を容易にすることができると共に、手摺を確実かつ強固に固定することができる。
【００１５】
また、請求項１，２記載の発明によれば、手摺杆を上方から見た場合、上端に断面円弧状の把持面が位置するので、全体の厚味を薄く印象付けることができ、手摺の存在による違和感を抑制することができる。また、もたれ面が把持面の外側から下方に向かって漸次外方側に緩やかに隆起する曲線をなすので、作業者が手摺杆に寄りかかった際に、作業者の体の曲線にフィットして、違和感をなくすことができる。また、ブラケットをブラケットの把持面及びもたれ面に連続する第１の外表面と、この第１の外表面に連続する第２の外表面とで形成することにより、ブラケットの外形を３次曲線で立体的に形成することができ、美観の向上を図ることができる。更には、ブラケットの把持面及びもたれ面に連続する外表面により、作業者の衣服に引掛けることのない形状とすることができる。
【００１６】
請求項３記載の発明は、請求項１又は２記載のもたれ用手摺において、上記手摺杆を、アルミニウム製押出形材にて形成される手摺杆本体と、この手摺杆本体の外表面に被着される合成樹脂製の手摺外装材とで形成し、ブラケットを合成樹脂製材にて形成し、このブラケットの固定部を、上記手摺杆本体の中空部内に嵌挿可能な突片にて形成すると共に、ブラケットの固定部に、手摺杆の端部外表面を呑み込むフランジ部を形成し、かつ、手摺杆の裏面側から挿通される固定ねじを突片に螺合して固定することを特徴とする。
【００１７】
このように構成することにより、手摺杆本体とブラケットとの外装を合成樹脂によって形成することができるので、手摺杆本体とブラケットとに一体感を表すことができる。また、ブラケットの固定部を、手摺杆本体の中空部内に嵌挿し、手摺杆の裏面側から挿通される固定ねじによって取り付けることにより、手摺杆本体とブラケットとの連結部の強度を増すことができると共に、手摺杆本体とブラケットとの固定を確実にすることができる。また、固定ねじの取付部を上面及び前面側から目隠しすることができるので、美観の向上が図れる。
【００１８】
また、手摺杆を切断することによって切断端部が均一な面を形成しない場合や、切断によって生じたバリを、ブラケットの固定部に形成されたフランジ部によって覆い被すことができるので、手摺杆の端部仕上げ処理を行う必要がなく、施工作業が容易になると共に、手摺杆とブラケットとの連結部の美観を向上させることができる。
【００１９】
請求項４記載の発明は、請求項１ないし３のいずれかに記載のもたれ用手摺において、上記ブラケットの取付部に、一端が開口する取付座の収納部を設けると共に、収納部における対向する側部に取付座を摺動可能に案内する嵌合溝を形成してなることを特徴とする。
【００２０】
このように構成することにより、ブラケットの収納部に形成された嵌合溝に取付座が嵌合されるので、ブラケットと取付座との取り付けを確実にすることができる。
【００２１】
【発明の実施の形態】
以下に、この発明のもたれ用手摺について、添付図面に基づいて詳細に説明する。
【００２２】
図１は、この発明のもたれ用手摺の取付状態を示す斜視図、図２は、もたれ用手摺の組立て状態の外面を示す斜視図（ａ）及び、（ａ）の裏面を示す斜視図（ｂ）、図３は、図１のＩ−Ｉ線に沿う断面図、図４は、図１のII−II線に沿う断面図、図５は、図２のIII−III線に沿う断面図、図６は、図２のIV−IV線に沿う断面図、図７は、もたれ用手摺の組付け状態を示す分解斜視図、図８は、もたれ用手摺の取付状態を示す斜視図、図９は、もたれ用手摺の平面図（ａ）、正面図（ｂ）、底面図（ｃ）、裏面図（ｄ）及びブラケットの横側面図（ｅ）、図１０は、もたれ用手摺を形成するブラケットの裏面部を示す分解斜視図である。
【００２３】
上記もたれ用手摺Ｈは、図１及び図２に示すように、上端に把持面１２を有し、外側にもたれ面１１を有する手摺杆１と、この手摺杆１の両端部をそれぞれ固定すると共に、取付基体であるキャビネットＣのカウンタ８の下方に配設される幕板９に、後述する取付座７と取付ねじ７８を介して取り付けられるブラケット２とで主に構成されている。
【００２４】
上記手摺杆１は、図１、図２、図７及び図８に示すように、キャビネットＣのカウンタ８の前面部に対して平行に延在する垂直状の内側壁１３と、この内側壁１３の下端から外方に向かってＬ字状に折曲される底面１４と、上記内側壁１３の上端から上外方に折曲され略円弧状に形成される把持面１２と、この把持面１２の外側から下方に向かって漸次外方側に緩やかに隆起する曲線状のもたれ面１１とで中空状に形成されている。また、手摺杆１の内側壁１３の切断端部１６には、後述するブラケット２の固定部４に突設される突片４１に形成される２つのねじ受部４６に連通するように、ねじ取付孔１５が穿設されている。
【００２５】
この場合、手摺杆１はアルミニウム製押出形材にて形成される手摺杆本体１７と、この手摺杆本体１７の外表面に被着される合成樹脂製の手摺外装材１８とで形成されている。また、上記手摺外装材１８は、二層に形成されており、内側の合成樹脂の外側に例えば木粉入りの合成樹脂層が被着して形成されている（図５、図６参照）。
【００２６】
上記ブラケット２は、合成樹脂製部材にて形成されており、図１ないし図７に示すように、キャビネットＣのカウンタ８の下方に配設される幕板９に、後述する取付座７を介して例えば取付ねじ７８によって取り付けられる取付部５と、この取付部５からキャビネットＣの前上方側に曲線状に延在する支持部３と、この支持部３の先端側に手摺杆１に向かって水平方向に突設すると共に、手摺杆１の中空部内に嵌合可能な固定部４とによって形成されている。
【００２７】
上記支持部３は、図２及び図９に示すように、手摺杆１の把持面１２に連続する上部外表面３１と、この上部外表面３１から前及び外下方に向かって曲面状に連続し、手摺杆１のもたれ面１１に連続する側部外表面３２とからなる第１の外表面３３と、上部外表面３１から側部外表面３２と反対側に曲面状に屈曲されて、下方の取付部５に延在する内側部外表面３４と、この内側部外表面３４の下端から側部外表面３２の下端に向かって曲面状に屈曲すると共に、側部外表面３２の下方に連続して延在する下部外表面３５とからなる第２の外表面３６とによってカウンタ８に対して開口する中空状に形成されている。また、第１の外表面３３と第２の外表面３６とを有す支持部３の中空部内には、図１０に示すように、側部外表面３２と内側部外表面３４との内部を水平に連続する仕切壁３７が形成されており、この仕切壁３７によって仕切壁３７の上方に開口する上部開口部６と、下方に開口する取付部５とに分割されている。
【００２８】
なお、この場合、上部開口部６は、図９（ｅ）及び図１０に示すように、側面視略Ｌ字状に形成されており、上部開口部６内の中央付近には、上部開口部６に向かって突出する円柱体にねじ孔を設けたキャップ用ねじ受部６３が形成されている。この上部開口部６には、側面視略Ｌ字状のキャップ６１が閉塞され、このキャップ６１を貫通するキャップ用取付ねじ６２をキャップ用ねじ受部６３に螺合することによって固定されている。なお、キャップ６１は、ブラケット２と同様に、合成樹脂製部材にて形成されている。
【００２９】
上記固定部４は、図５、図６及び図７に示すように、支持部３の内側部外表面３４の先端側から手摺杆１に向かって突設し、断面形状が手摺杆本体１７の中空部内に嵌挿可能な中空状の突片４１によって形成される。また、上記突片４１の基端部４２には、基端部４２を囲むように段部４３が形成されている。この段部４３の全周に渡って溝部４４が形成されており、段部４３の外周には、手摺杆１とブラケット２を連結する際、固定部４の段部４３に当接する手摺杆１の端部外周面１９を呑み込む薄肉のフランジ部４５が形成されている（図５参照）。
【００３０】
このように、突片４１の基端部４２に溝部４４を有する段部４３を形成すると共に、段部４３の外周にフランジ部４５を形成することにより、手摺杆１の端部外周面１９を呑み込むことができるので、手摺杆１の切断端部１６が均一な面を形成していない場合や、バリ等がある場合に、フランジ部４５によって覆うことができ、手摺杆１とブラケット２の連結部の美観の向上を図ることができる。
【００３１】
なお、上記フランジ部４５は、支持部３の上部外表面３１及び側部外表面３２とで形成される第１の外表面３３の延長上にあり、連続されて形成されている。手摺杆１とブラケット２を連結した状態では、フランジ部４５が手摺杆１の端部外周面１９を呑み込むため、厳密には手摺杆１の把持面１２及びもたれ面１１とフランジ部４５との間に段が生じるが、フランジ部４５の肉厚は薄いため、無視できる許容範囲である。また、上記突片４１の中空部内には、突片４１と手摺杆１を固定する際に、手摺杆１の裏面から固定ねじ４７を取り付けるためのねじ受部４６が形成されている。
【００３２】
上記取付部５は、図２（ｂ）、図３、図４及び図７に示すように、支持部３の側部外表面３２と内側部外表面３４と下部外表面３５及び仕切壁３７の端部によって矩形状に開口して形成されている。この取付部５の一端すなわち下部外表面３５の端部には開口段部５１が設けられ、仕切壁３７及び両側部５６，５７すなわち側部外表面３２及び内側部外表面３４の端部によって下向きに開口するコ字状の収納部５３が形成されている。
【００３３】
上記収納部５３の対向する側部５６，５７の内側には、後述する取付座７を摺動可能に嵌合（案内）する嵌合溝５４が設けられており、取付部５内部には、取付座７と当接すると共に、開口段部５１と面一になる上面部と、取付座７を取付ねじ７７によって取り付けるための略筒状の取付ねじ受部５５が、側部外表面３２及び内側部外表面３４の内面に沿って４個形成されている。また、開口段部５１の中央には、取付座７を収納部５３に取り付ける際に、取付座７に取り付けられた例えばナット等の雌ねじ部材７５が開口段部５１と干渉しないように切欠き部５２が形成されている。
【００３４】
上記取付座７は、図３、図４及び図７に示すように、上記幕板９の取付面９ａに当接し得る当接部７１と、この当接部７１の両側端から裏面側に略直角に折曲される折曲段部７２と、折曲段部７２の先端から当接部７１と平行に折曲されて側方に向かって延在する取付片７３とからなる略ハット状に形成されている。
【００３５】
この場合、当接部７１には、図３、図４及び図７に示すように、上下部位に適宜間隔をおいて２つの取付ねじ用孔７４が穿設されると共に、当接部７１の裏面には、この取付ねじ用孔７４と連通するように例えばナット７５が溶接等により固定されている。
【００３６】
このように当接部７１に、取付ねじ用孔７４及びこれに連通するナット７５を形成することにより、もたれ用手摺Ｈを幕板９に取り付ける際、幕板９の裏面側から幕板９に穿設された貫通孔９１を貫通する取付ねじ７８を当接部７１のナット７５に螺合して、幕板９に取付座７（ブラケット２）を固定することができる。なお、ナット７５に代えて当接部７１にバーリング加工した孔を設け、この孔に雌ねじを刻設するようにしてもよい。
【００３７】
一方、上記両取付片７３には、図３及び図７に示すように、それぞれの上下部位に上記取付部５に形成された取付ねじ受部５５に連通すると共に、取付ねじ７７を挿通する取付ねじ用孔７６が穿設されている。
【００３８】
上記のように構成される取付座７は、ブラケット２の収納部５３の対向する側部５６，５７の嵌合溝５４に案内されて収納部５３内に収納され、取付ねじ用孔７６に挿通される取付ねじ７７を取付ねじ受部５５に螺合することによってブラケット２に一体に設けられている。
【００３９】
なお、上記取付座７は、必ずしも上記に説明した略ハット状の形状に限定されるものではなく、例えば、図１１に示すように、当接部及び取付片が一体に形成される矩形状の厚板７９によって形成してもよい。この場合、取付ねじ用孔７６には、例えば座ぐり等の凹部７６ａを形成して、取付ねじ７７の頭部を収容するようにしておく方が好ましい。
【００４０】
なお、この場合、取付座７は、例えばステンレス製板又はスチール製板をプレス加工等によって形成されている。
【００４１】
上記のように構成されるもたれ用手摺Ｈを、キャビネットＣのカウンタ８の下方に配設された幕板９に取り付けるには、まず、手摺杆１を取付位置に適した長さに切断すると共に、手摺杆１の内側壁１３の切断端部１６に、ブラケット２の突片４１に形成されたねじ受部４６に連通するようにねじ取付孔１５を穿設する。
【００４２】
また、ブラケット２の取付部５に形成された収納部５３の開口段部５１から、収納部５３の両側部５６，５７に形成された嵌合溝５４に取付座７の両取付片７３の両端部を嵌合すると共に、上方にスライド（摺動）させて、取付座７を取付部５の取付位置に配置し、取付ねじ用孔７６に取付ねじ７７を挿通し、取付部５の取付ねじ受部５５に螺合することによって取付座７を取付部５に固定する。
【００４３】
次に、図７に示すように、手摺杆１の中空部内に固定部４の突片４１を嵌挿し、手摺杆１の切断端部１６を固定部４の段部４３に当接した状態で、固定ねじ４７を手摺杆１のねじ取付孔１５を貫通し、突片４１に形成されるねじ受部４６に螺合することによって手摺杆１とブラケット２を連結する。この状態で、手摺杆１の端部外周面１９は、ブラケット２の固定部４に形成されたフランジ部４５によって呑み込まれた状態になる。
【００４４】
次に、上記のように組み付けられたもたれ用手摺Ｈのブラケット２に設けられた取付座７の当接部７１を、幕板９に予め設けられた貫通孔９１の部位に当接する。この状態で、幕板９の裏面側から貫通孔９１内に取付ねじ７８を貫挿し、取付ねじ７８を取付座７のナット７５に螺合することによって、幕板９にもたれ用手摺Ｈを取付固定する。
【００４５】
したがって、上記のようにもたれ用手摺Ｈを構成するので、キャビネットＣのカウンタ８の前面部にもたれ用手摺Ｈを取り付ける場合、幕板９の裏面側から取付ねじ７８によって取り付けることができるので、ブラケット２の外表面に取付ねじ７８の取付部を形成する必要がなく、取付部を塞ぐキャップなどを形成する必要がないので、ブラケット２の形状を立体的に自在に形成することができ、美観の向上が図れる。
【００４６】
なお、上記実施形態では、もたれ用手摺ＨをキャビネットＣのカウンタ８の下方に配設された幕板９に直接取り付ける場合について説明したが、必ずしもこのような取付構造に限定されるものではない。例えば、図１２ないし図１４に示すように、もたれ用手摺Ｈに、キャビネットＣの幕板９に取り付けられる取付体例えば幕板体９０を予め取付固定して、もたれ用手摺ＨをキャビネットＣの幕板９に取り付けるようにしてもよい。
【００４７】
この場合、上記幕板体９０は、図１２及び図１３に示すように、もたれ用手摺Ｈの長さよりも若干長い矩形状の板体に形成されており、この幕板体９０の裏面には、上、下部にそれぞれ下向きのＬ字状係止凸条９２を有する係止金具９３が例えば取付ねじ９３Ａ（図１３参照）によって装着されている。また、幕板体９０には、ブラケット２と幕板体９０とを固定する取付ねじ９４の取付孔９５が穿設されている。また、幕板体９０及び係止金具９３には、幕板９に穿設された貫通孔９６を挿通する取付ねじ７８Ａのねじ受孔９７が設けられている（図１２及び図１３参照）。
【００４８】
なお、この場合、ブラケット２と幕板体９０とは、上記実施形態と同様に、ブラケット２の取付部５に設けられる取付座７を介して固定されている。すなわち、上記ブラケット２の取付部５に設けられた取付座７の当接部７１に、幕板体９０を当接した状態で、幕板体９０の裏面から取付孔９５を挿通する取付ねじ９４を取付座７に形成されたナット７５に螺合することによって、ブラケット２と幕板体９０は固定されている（図１４参照）。
【００４９】
このように、幕板体９０は、もたれ用手摺Ｈと一体に形成されるので、取付ねじ９４はブラケット２の表面に露出することがない。なお、ブラケット２と幕板体９０とを一体に形成した後、取付ねじ９３Ａをもって係止金具９３が幕板体９０に固定される。なお、取付ねじ９４の頭部を皿状に形成し、取付孔９５の開口端に座ぐりを施すことにより、取付ねじ９４の頭部が突出することがない。
【００５０】
一方、キャビネットＣのカウンタ８の下方に配設される幕板９の取付面９ａには、係止金具９３の係止凸条９２と係脱可能な係止受部９８が突設されている。この場合、係止受部９８は、係止金具９３の上、下部の係止凸条９２にそれぞれ係脱可能に係合する上下部に平行な上向きのＬ字状係止凹条９９を具備している。この場合、この係止受部９８は、図示しない取付ねじによって幕板９の取付面９ａに装着されている。
【００５１】
なお、上記係止金具９３及び係止受部９８は、例えばアルミニウム製押出形材あるいは鋼製板材をプレス加工したものなどで形成されている。
【００５２】
なお、図１２ないし図１４に示す実施形態において、その他の部分は、上記第一実施形態と同じであるので、同一部分には同一符号を付して説明は省略する。
【００５３】
上記のように構成される幕板体９０を、予め、もたれ用手摺Ｈのブラケット２に取付固定することにより、幕板体９０に装着された係止金具９３の係止凸条９２を、キャビネットＣの幕板９に装着された係止受部９８の係止凹条９９に係止させて仮固定することができる。そして、この状態で、幕板９の裏面から貫通孔９６を挿通する取付ねじ７８Ａを幕板体９０のねじ受孔９７に螺合させることによって、もたれ用手摺ＨをキャビネットＣのカウンタ８の下方に配設された幕板９に取付固定することができる。
【００５４】
したがって、もたれ用手摺Ｈの取付を容易にすることができると共に、もたれ用手摺Ｈを確実かつ強固に固定することができる。また、幕板体９０とブラケット２を、幕板体９０の裏面から挿通される取付ねじ９４によって固定することにより、ブラケット２の外方部に取付ねじ９４の取付部等を形成する必要がなく、ブラケット２の外方部に取付部に取付部等を塞ぐキャップ等を被着する必要がないので、構成部材の削減が図れると共に、ブラケット２の形状を自由に形成例えばデザインすることができる。
【００５５】
なお、上記実施形態では、手摺杆１を、アルミニウム製押出形材にて形成される手摺杆本体１７と、手摺杆本体１７の外表面に被着される合成樹脂製の手摺杆外装材１８とで構成し、ブラケット２を合成樹脂製材にて形成する場合について説明したが、必ずしもこのような構造とする必要はない。例えば、手摺杆１をアルミニウム製押出形材にて形成し、ブラケット２をアルミニウム製鋳物にて形成してもよい。この場合、ブラケット２に取付座７を一体に形成することができる。
【００５６】
【発明の効果】
以上に説明したように、この発明のもたれ用手摺は、上記のように構成されているので、以下のような優れた効果が得られる。
【００５７】
（１）請求項１記載の発明によれば、取付基体に、ブラケットを取付基体の裏面側から取付固定するので、ブラケットの外方部に取付ねじの取付部等を形成する必要がなく、ブラケットの外方部に取付部等を塞ぐキャップ等を被着する必要がないので、構成部材の削減が図れると共に、ブラケットの形状を自由に形成例えばデザインすることができ、美観の向上を図ることができる。
【００５８】

A bottom surface 14 bent in an L shape outward from the lower end of the inner wall, a gripping surface 12 bent upward and outward from the upper end of the inner side wall 13, and the gripping surface 12. It is formed in a hollow shape with a curved leaning surface 11 that gradually rises outward from the outside of the plate. Further, the cut end portion 16 of the inner wall 13 of the handrail 1 is screwed so as to communicate with two screw receiving portions 46 formed on the protruding piece 41 protruding from the fixing portion 4 of the bracket 2 described later. A mounting hole 15 is formed.
[0025]
  In this case, the handrail rod 1 is formed of a handrail rod main body 17 formed of an aluminum extruded profile and a handrail exterior member 18 made of synthetic resin that is attached to the outer surface of the handrail rod main body 17. . Further, the handrail exterior material 18 is formed in two layers, and is formed by adhering a synthetic resin layer containing, for example, wood powder on the outside of the inner synthetic resin (see FIGS. 5 and 6).
[0026]
  The bracket 2 is formed of a synthetic resin member. As shown in FIGS. 1 to 7, the bracket 2 is disposed on a curtain plate 9 disposed below the counter 8 of the cabinet C via a mounting seat 7 described later. For example, the attachment portion 5 attached by the attachment screw 78, the support portion 3 extending in a curved shape from the attachment portion 5 to the front upper side of the cabinet C, and toward the handrail 1 on the distal end side of the support portion 3 It is formed by a fixing portion 4 that protrudes in the horizontal direction and can be fitted in the hollow portion of the handrail 1.
[0027]
  As shown in FIGS. 2 and 9, the support portion 3 is continuous in a curved shape from the upper outer surface 31 continuous to the gripping surface 12 of the handrail 1 and from the upper outer surface 31 forward and outward. The first outer surface 33 including a side outer surface 32 continuous with the leaning surface 11 of the handrail 1 and the upper outer surface 31 is bent in a curved shape on the opposite side to the side outer surface 32, The inner part outer surface 34 that extends to the mounting part 5, is bent in a curved shape from the lower end of the inner part outer surface 34 toward the lower end of the side part outer surface 32, and is continuous below the side part outer surface 32. It is formed in a hollow shape opened to the counter 8 by a second outer surface 36 composed of a lower outer surface 35 extending in the direction. Further, in the hollow portion of the support portion 3 having the first outer surface 33 and the second outer surface 36, as shown in FIG. 10, the insides of the side outer surface 32 and the inner outer surface 34 are formed. A horizontally continuous partition wall 37 is formed. The partition wall 37 is divided into an upper opening 6 that opens above the partition wall 37 and a mounting portion 5 that opens downward.
[0028]
  In this case, the upper opening 6 is formed in a substantially L shape in a side view as shown in FIGS. 9E and 10, and there is an upper opening near the center in the upper opening 6. A screw receiving portion 63 for a cap provided with a screw hole in a cylindrical body projecting toward 6 is formed. A cap 61 that is substantially L-shaped in side view is closed in the upper opening 6, and is fixed by screwing a cap mounting screw 62 that penetrates the cap 61 into a cap screw receiving portion 63. The cap 61 is formed of a synthetic resin member, like the bracket 2.
[0029]
  As shown in FIGS. 5, 6, and 7, the fixing portion 4 protrudes from the front end side of the inner outer surface 34 of the support portion 3 toward the handrail 1, and has a cross-sectional shape of the handrail main body 17. It is formed by a hollow protrusion 41 that can be inserted into the hollow portion. Further, a stepped portion 43 is formed at the base end portion 42 of the protruding piece 41 so as to surround the base end portion 42. A groove portion 44 is formed over the entire circumference of the step portion 43, and the handrail rod 1 that contacts the step portion 43 of the fixing portion 4 when the handrail rod 1 and the bracket 2 are connected to the outer periphery of the step portion 43. A thin flange portion 45 that squeezes the outer peripheral surface 19 is formed (see FIG. 5).
[0030]
  In this way, the stepped portion 43 having the groove portion 44 is formed at the base end portion 42 of the projecting piece 41 and the flange portion 45 is formed at the outer periphery of the stepped portion 43, so that the end outer peripheral surface 19 of the handrail 1 is formed. Since it can be squeezed, it can be covered with the flange portion 45 when the cut end portion 16 of the handrail rod 1 does not form a uniform surface or when there is a burr or the like, and the handrail rod 1 and the bracket 2 can be connected. The aesthetics of the club can be improved.
[0031]
  The flange portion 45 is on an extension of the first outer surface 33 formed by the upper outer surface 31 and the side outer surface 32 of the support portion 3 and is formed continuously. In a state where the handrail rod 1 and the bracket 2 are connected, the flange portion 45 squeezes the outer peripheral surface 19 of the end portion of the handrail rod 1, so strictly speaking, between the grip surface 12 and the leaning surface 11 of the handrail rod 1 and the flange portion 45. However, since the thickness of the flange portion 45 is thin, the tolerance is negligible. Further, a screw receiving portion 46 for attaching a fixing screw 47 from the back surface of the handrail rod 1 when the projecting piece 41 and the handrail rod 1 are fixed is formed in the hollow portion of the protrusion piece 41.
[0032]

A U-shaped storage portion 53 that is open at the top is formed.
[0033]
  A fitting groove 54 for slidably fitting (guide) a mounting seat 7 described later is provided inside the opposing side portions 56 and 57 of the storage portion 53. An upper surface portion that is in contact with the mounting seat 7 and is flush with the opening step portion 51, and a substantially cylindrical mounting screw receiving portion 55 for mounting the mounting seat 7 with mounting screws 77 are provided on the side outer surface 32 and the inner side. Four pieces are formed along the inner surface of the outer surface 34. Further, at the center of the opening step 51, a notch is provided so that a female screw member 75 such as a nut attached to the attachment seat 7 does not interfere with the opening step 51 when the attachment seat 7 is attached to the storage portion 53. 52 is formed.
[0034]
  As shown in FIGS. 3, 4, and 7, the mounting seat 7 has a contact portion 71 that can contact the mounting surface 9 a of the curtain plate 9, and substantially from the both side ends of the contact portion 71 to the back side. In a substantially hat shape comprising a bent stepped portion 72 bent at a right angle and a mounting piece 73 bent in parallel with the contact portion 71 from the tip of the bent stepped portion 72 and extending sideways. Is formed.
[0035]
  In this case, as shown in FIGS. 3, 4, and 7, the attachment portion 71 is provided with two mounting screw holes 74 at an appropriate interval in the upper and lower portions, and For example, a nut 75 is fixed to the rear surface by welding or the like so as to communicate with the mounting screw hole 74.
[0036]
  In this way, by forming the mounting screw hole 74 and the nut 75 communicating therewith in the contact portion 71, when the leaning handrail H is attached to the curtain plate 9, the back surface side of the curtain plate 9 is connected to the curtain plate 9. The mounting seat 7 (bracket 2) can be fixed to the curtain plate 9 by screwing a mounting screw 78 penetrating through the drilled through hole 91 into the nut 75 of the contact portion 71. Instead of the nut 75, a burring hole may be provided in the contact portion 71, and a female screw may be formed in the hole.
[0037]
  On the other hand, as shown in FIGS. 3 and 7, both the mounting pieces 73 are connected to the mounting screw receiving portions 55 formed in the mounting portion 5 in the respective upper and lower portions, and the mounting screws 77 are inserted. A screw hole 76 is formed.
[0038]
  The mounting seat 7 configured as described above is guided in the fitting groove 54 of the opposing side portions 56 and 57 of the storage portion 53 of the bracket 2 and stored in the storage portion 53, and is inserted into the mounting screw hole 76. The mounting screw 77 is integrally provided on the bracket 2 by screwing the mounting screw 77 to the mounting screw receiving portion 55.
[0039]
  The mounting seat 7 is not necessarily limited to the substantially hat-shaped shape described above. For example, as shown in FIG. 11, the mounting seat 7 has a rectangular shape in which the contact portion and the mounting piece are integrally formed. A thick plate 79 may be used. In this case, it is preferable to form a recess 76a such as a spot facing in the mounting screw hole 76 so as to accommodate the head of the mounting screw 77.
[0040]
  In this case, the mounting seat 7 is formed by pressing a stainless plate or a steel plate, for example.
[0041]
  To attach the leaning handrail H configured as described above to the curtain plate 9 disposed below the counter 8 of the cabinet C, first, the handrail rod 1 is cut to a length suitable for the mounting position. The screw mounting hole 15 is bored in the cut end portion 16 of the inner wall 13 of the handrail 1 so as to communicate with the screw receiving portion 46 formed on the protruding piece 41 of the bracket 2.
[0042]
  Further, both end portions of both mounting pieces 73 of the mounting seat 7 are inserted into the fitting grooves 54 formed on both side portions 56 and 57 of the storage portion 53 from the opening step portion 51 of the storage portion 53 formed in the mounting portion 5 of the bracket 2. The mounting seat 7 is placed at the mounting position of the mounting portion 5, the mounting screw 77 is inserted into the mounting screw hole 76, and the mounting screw of the mounting portion 5 is inserted. The mounting seat 7 is fixed to the mounting portion 5 by screwing into the receiving portion 55.
[0043]
  Next, as shown in FIG. 7, the protruding piece 41 of the fixing portion 4 is inserted into the hollow portion of the handrail rod 1, and the cut end portion 16 of the handrail rod 1 is in contact with the stepped portion 43 of the fixing portion 4. The handrail rod 1 and the bracket 2 are connected by screwing the fixing screw 47 through the screw mounting hole 15 of the handrail rod 1 and screwing into the screw receiving portion 46 formed on the protruding piece 41. In this state, the outer peripheral surface 19 of the end portion of the handrail 1 is pinched by the flange portion 45 formed in the fixing portion 4 of the bracket 2.
[0044]
  Next, the contact portion 71 of the mounting seat 7 provided on the bracket 2 of the leaning handrail H assembled as described above is brought into contact with the portion of the through hole 91 provided in the curtain plate 9 in advance. In this state, the mounting screw 78 is inserted into the through hole 91 from the back side of the curtain plate 9 and the mounting screw 78 is screwed into the nut 75 of the mounting seat 7 so that the handrail H for leaning is attached to the curtain plate 9.

[0045]
  Accordingly, since the leaning handrail H is configured as described above, when the leaning handrail H is attached to the front surface portion of the counter 8 of the cabinet C, the leaning handrail H can be attached from the back side of the curtain plate 9 by the attachment screw 78. Since it is not necessary to form a mounting portion of the mounting screw 78 on the outer surface of 2 and to form a cap or the like for closing the mounting portion, the shape of the bracket 2 can be freely formed in three dimensions. Improvement can be achieved.
[0046]
  In the above embodiment, the case where the leaning handrail H is directly attached to the curtain plate 9 disposed below the counter 8 of the cabinet C has been described, but the present invention is not necessarily limited to such an attachment structure. For example, as shown in FIGS. 12 to 14, a mounting body attached to the curtain plate 9 of the cabinet C, for example, a curtain plate body 90 is attached and fixed in advance to the leaning handrail H, and the leaning handrail H is attached to the curtain of the cabinet C. You may make it attach to the board 9. FIG.
[0047]
