【発明の属する技術分野】
この発明は、高齢者や身体障害者などの自助用又は介護用として主に一般住宅や介護施設などの玄関や居室、或いは浴室、便所などの出入り口開口を水平方向に横断する形に設置され、高齢者や身体障害者が掴まり歩きができる、出入り口横断用の着脱自在手摺りの技術分野に属し、更に言えば、出入り口開口に常設することが可能で、出入り口のドアや引き戸などの開閉に支障がなく、また、健常者や高齢者、身体障害者などが出入り口を通行する際には邪魔にならないように取り外すか又は回転して退避させておくこと、或いは出入り口開口に沿って縦に仮止めして縦の手摺りとして利用することもできる、出入り口横断用の着脱自在手摺りに関する。
【０００２】
【従来の技術】
従来、高齢者や身体障害者の自助用又は介護用手摺りを、出入り口開口についても水平方向に横断させて配置し手摺りの連続性を確保すること、そして、同手摺りが無用の場合、又は健常者や高齢者、身体障害者などが出入り口を通行する際には、邪魔にならないように取り外すか又は退避させて少なくとも出入り口を全面開放の状態にできる、出入り口横断用の着脱自在手摺りは既に公知に属する（例えば特許文献１を参照）。
【０００３】
【特許文献１】
特開２００１−１０７５３０号公報
【０００４】
【発明が解決しようとする課題】
従来の上記特許文献１記載の出入り口横断用の着脱自在手摺りは、その一側端部が建造物壁面に回動可能に支持され、他側端部は建造物壁面の支持具に対して着脱可能に支持された構成である。そして、支持具に対して手摺りを着脱可能に支持させる構成として、特許文献１記載の発明では、その図１１〜図１４及び図１６〜図１８に詳示されている通り、握り玉を掴んで引き上げ抜き差し操作する進退ピンによる機構が採用されている。
【０００５】
したがって、出入り口横断用の着脱自在手摺りの他側端部を、建造物壁面の支持具に対して着脱するためには、片手で手摺りの他側端部を握り持ち、他方の手で進退ピンの握り玉を掴んで引き上げる操作をすることが必要条件である。要するに両手による操作をしなければならない。
【０００６】
そのため出入り口を通行しようとする者が両手に荷物を持っていたり、或いは高齢者や身体障害者を少なくとも片手で支えた介助状態の場合には、上記手摺りの着脱操作は不可能である。一旦荷物を床上へ下ろしたり、又は介助中の高齢者や身体障害者を他の手摺りなどに掴まらせておいてから、当該手摺りの着脱操作を行うほかはなく、甚だ使い勝手が悪く不便である。
【０００７】
したがって、本発明の目的は、手摺りの着脱操作を、少なくとも片手によって簡単、確実にでき、しかも手摺りを取り外したり回転して退避させた場合でも構成部品等が紛失する不具合は決して生じないし、また、縦に仮止めした手摺りはそのまま縦の手摺りとしても使用可能である、出入り口横断用の着脱自在手摺りを提供することにある。

【００１０】
請求項３に記載した発明に係る出入り口横断用の着脱自在手摺りは、
手摺りが、出入り口開口を水平方向に横断させて配置され、その一側端部は出入り口開口の片側の建造物壁面へ着脱自在に設置され、他側端部は他方の建造物壁面へ回転自在に設置して成るもので、

前記他側位置の手摺り支持用ブラケットにはヒンジ支持板が設けられており、手摺りの他側端部の前記ヒンジ板は、その長孔へ通したヒンジピンにより前記ヒンジ支持板と回転可能に連結されていること、
前記他側位置の手摺り支持用ブラケットの上方に位置する手摺りの仮止め用ブラケットは、手摺りの一側端部が前記ヒンジピンを中心として上方へ約９０°回転すると同手摺りの嵌合板のフック部を掛け止め可能な仮止め具を有すること、

【００１１】
請求項４に記載した発明は、請求項１又は２又は３に記載した出入り口横断用の着脱自在手摺りにおいて、
出入り口開口の両側の建造物壁面が手摺りと平行に形成されている場合に、前記建造物壁面の手摺り支持位置に設置された手摺り支持用ブラケットは、同建造物壁面へ固定された取付板から垂直方向に所定の寸法で突き出された支持板を有し、該支持板に垂直な板状の係止片が内向きに設けられた構成であることを特徴とする。
【００１２】

出入り口開口の両側の建造物壁面が手摺りと直角に形成されている場合に、前記建造物壁面の手摺り支持位置に設置された手摺り支持用ブラケットは、同建造物壁面へ固定された取付板に垂直な板状の係止片が内向きに設けられた構成であることを特徴とする。
【００１３】
【発明の実施形態】
以下に、図示した本発明の実施形態を説明する。
図１は本発明に係る出入り口横断用の着脱自在手摺り１と、出入り口開口Ａ、及び同開口に取り付けられたドアＢ、並びに開口両側の建造物壁面Ｃに設置された左右の手摺りＤ、Ｄとの関係を示している。
【００１４】
つまり、この出入り口横断用の着脱自在手摺り１は、出入り口開口Ａを水平方向に横断して配置され、もって左右に隣接する手摺りＤ、Ｄと一連の関係を確保するものである。その上で、当該手摺り１の両端部を開口両側の建造物壁面Ｃへ着脱自在に設置して成る。
【００１５】
図２〜図６は、請求項１記載の発明に係る実施形態を示したもので、上記出入り口横断用の着脱自在手摺り１の両端部には、下向きのコ字形状溝を有する嵌合板４、４が設けられている。この嵌合板４は、図５に例示したように、平鋼板等をＵ字形に折り曲げ加工して成るもので、端末キャップ３と一体構造に製作されており、同端末キャップ３を手摺り１の端部へ嵌め込み、図６のように止めネジ５０で固定して設置されている。因みに、手摺り１には、外径が３５ｍｍ前後のいわゆる丸棒状の木材が使用される。
【００１６】
前記嵌合板４の両側壁面には、先方に向かって２０°程度の緩やかな角度で下る傾斜状に長孔５が形成され、同長孔５へ水平方向に通したロックピン６が長孔５の長手方向へ移動自在に設置されている。
【００１７】
一方、出入り口開口Ａの両側の建造物壁面Ｃの手摺り支持位置には、手摺り１の両端部の前記嵌合板４、４の先端位置を規制する配置で手摺り支持用ブラケット２、２が設置されている。この手摺り支持用ブラケット２は、建造物壁面Ｃが手摺り１と平行な場合のもので、図５で明らかなように、壁面Ｃへ止めネジ５１で固定された取付板７から垂直方向に、手摺り１の取り付けが壁面Ｃから適度に離れる寸法（例えば５０ｍｍ程度）だけ突き出された支持板２ａを有し、この支持板２ａの片面（内向き面）から内向きに垂直な姿勢で、手摺り１の両端部の前記嵌合板４のコ字形状溝が嵌る板状の係止片８が設けられている（請求項４記載の発明）。図３で明らかなように、手摺り支持用ブラケット２の支持板２ａが、手摺り１の両端部の前記嵌合板４の先端位置を規制する配置で設置されている。
【００１８】
手摺り支持用ブラケット２の前記係止片８の内向きへの突き出し寸法は、図４の２点鎖線による図示で明らかなように、手摺り１の嵌合板４における前記長孔５内を移動するロックピン６を同長孔５の内端寄りに位置させると通過し得る寸法とされている。また、同係止片８において、嵌合板４のコ字形状溝の上面壁４ａおよびロックピン６が載る上辺部８ａの形状は、図示例の場合は約１／４円弧形状とされている。これは要するに支持板２ａの位置から内方（図３に示す左右の手摺り支持用ブラケット２、２の位置から見て内向き）に向かって、前記ロックピン６を長孔５に沿って内端寄り位置へ移動させるのに適した形状の一例を示したものである。従って、前記した１／４円弧形状の限りではなく、内方へ向かって適度に下る傾斜面等であっても良い。
【００１９】
同係止片８の下辺部８ｂは、嵌合板４のコ字形状溝の上面壁４ａが当該係止片８の上辺部８ａへ載った状態で（例えば図２を参照）、前記ロックピン６がその自重の重力作用又は手先の操作等で長孔５内を外端寄り位置にまで移動可能な形状、好ましくは長孔５の上縁と一致した角度及び高さレベルの傾斜形状とされている。
【００２０】
従って、本発明の着脱自在手摺り１を、手摺り支持用ブラケット２から取り外す際には、図４の左側に２点鎖線で示したように、少なくとも手摺り１の一側端部を片手で握り持ち、且つその指先で嵌合板４のロックピン６を長孔５の内端寄り位置へ移動させて同手摺り１を持ち上げると簡単、確実に、手摺り支持用ブラケット２の係止片８から取り外せる。このとき他側端部の嵌合板４及びロックピン６は、当該手摺り１の一側端部が前記した手順で手摺り支持用ブラケット２から外されて持ち上げられる回転動作に追従して、その係止片８から円滑に抜け外れる。つまり、片手の操作で手摺り１を左右両方の手摺り支持用ブラケット２、２から取り外せるのである。
【００２１】
逆に、取り外された手摺り１を、左右の手摺り支持用ブラケット２、２の係止片８へ取り付ける際には、手摺り１の中央部を握り持ち、同手摺りを水平状態のまま図３のように両端部の嵌合板４、４を左右の係止片８、８に合わせて嵌めそのまま手を離す。手摺り１は自重により下がると、係止片８の上辺部８ａ上のロックピン６が長孔５を移動し、図２のように嵌合板４の上面壁４ａが係止片８の上辺部８ａに載った状態で下辺部８ｂにロックピン６が移動して自動的にロックされる。あるいは、手摺り１の一側端部を片手で握り持ち、且つ同手摺り１を図４のように適度に傾けて、先ずは他側端部の嵌合板４を該当する手摺り支持用ブラケット２の係止片８へ図４の右側部分に図示したように当てがい、しかる後に一側端部を下ろす回転操作を進める。そして、嵌合板４を係止片８へ嵌めると共に、同嵌合板４の上面壁４ａが係止片８の上辺部８ａに当たるまで嵌め込む。すると、上辺部８ａ上のロックピン６が長孔５に沿って内端寄り位置へと押し上げられ、ロックピン６が長孔５内を外端位置まで転がり下りて係止片８の下辺部８ｂへ止まる。したがって、手摺り１の取り付け操作も、片手のみで行うことができる（以上、請求項１記載の発明）。かくして、ロックピン６が一旦長孔５の外端寄りに位置すると、手摺り１は、如何なる方向に如何に大きな力を加えても手摺り支持用ブラケット２、２から抜け外れることは決してないのである。
【００２２】
次に、図７と図８は、建造物壁面Ｃが手摺り１と直角に形成されている場合の手摺り支持用ブラケット２’と、これに取り付ける手摺り１の実施形態を示している（請求項５記載の発明）。
この手摺り支持用ブラケット２’は、手摺り１と直角な建造物壁面Ｃへ止めネジ５１で固定した取付板７の片面に直接垂直な板状の係止片８が内向きに設けられた構成である。したがって、この係止片８へは、上記実施例と全く同様に、手摺り１の端部に設けた下向きのコ字形状溝を有する嵌合板４が嵌め込まれ、ロックピン６により止めることができる。
【００２３】
次に、図９と図１０は、請求項２に記載した発明に係る出入り口横断用の着脱自在手摺りの実施形態を示している。
本実施形態の場合も、手摺り１は、出入り口開口Ａを水平方向に横断させて配置され、その一側端部は出入り口開口Ａの片側の建造物壁面Ｃへ着脱自在に設置され、他側端部は他方の建造物壁面Ｃへ回転自在に設置して成る。
【００２４】
手摺り１の一側端部には、下向きのコ字形状溝を有する嵌合板４が設けられている。この嵌合板４の両側壁面に先方へ下る傾斜状の長孔５が形成され、同長孔５へ水平方向に通したロックピン６が長孔５の長手方向へ移動自在に設置された構成は上記の例と同じである。同手摺り１の他側端部には、手摺り１の長手方向に長い長孔１８を有するヒンジ板１９がやはり端末キャップ３により設けられている。
【００２５】
出入り口開口Ａの一側の建造物壁面Ｃの手摺り支持位置には、手摺り１の一側端部の前記嵌合板４の先端位置を規制する配置で上記した構成の手摺り支持用ブラケット２が、他側位置には、前記ヒンジ板１９の回転支持に適切な配置で手摺り支持用ブラケット２２が設置されている。
【００２６】
前記一側位置の手摺り支持用ブラケット２に、手摺り１の一側端部の前記嵌合板４のコ字形状溝が嵌る垂直な板状の係止片８が設けられていることは、上記第１実施形態と同じである。そして、同係止片８の内向きへの突き出し寸法は、手摺り１の一側端部の前記嵌合板４における前記長孔５内を移動するロックピン６が同長孔５の内端寄りに位置すると通過し得る寸法とされ、同係止片８において嵌合板４のコ字形状溝の上面壁４ａおよびロックピン６が載る上辺部８ａは、内方に向かって、前記ロックピン６を長孔５に沿って内端寄り位置へ移動させるのに適した形状とされ、同係止片８の下辺部８ｂは、嵌合板４のコ字形状溝の上面壁４ａが前記係止片８の上辺部８ａへ載った状態で前記ロックピン６が長孔５内をその外端寄り位置まで移動可能な形状とされていることも、上記実施形態と同じである。
【００２７】
他側位置の手摺り支持用ブラケット２２は、壁面Ｃへ止めネジ５１で固定した取付板２４から垂直に前方へ突き出した支持板２８に壁面Ｃと平行なヒンジ支持板２５が垂直に設けられている（図１３参照）。そして、手摺り１の他側端部の前記ヒンジ板１９は、その長孔１８へ通したヒンジピン２３により前記ヒンジ支持板２５と回転可能に連結されている。
【００２８】
図示した手摺り支持用ブラケット２２の場合、ヒンジ支持板２５は、上向きに開口された縦長矩形状で薄型の袋構造に構成され、その内側壁２５ａ（図１０の左側壁）は上半部が切り欠かれ、図９のようにヒンジ板１９が内側へ約９０°回転することを可能に構成している。同ヒンジ板１９の先端部は、長孔１８の先端部に位置するヒンジピン２３を中心として約１／４回転することが可能な１／４円弧形状に形成されている。ヒンジ支持板２５の外側壁２５ｂ（図１０の右側壁）は、上端まで連続しており、これが左側の内側壁２５ａと共に後述する手摺り１の垂直な姿勢保持部として働く構成とされている。つまり、ヒンジ板１９の幅寸と、縦長矩形状で薄型の袋構造に構成されたヒンジ支持板２５の中空部内における左右の内側壁２５ａと外側壁２５ｂの内法寸法とはほぼ等しく構成されている。
【００２９】
図９のように水平方向に配置され、左右の手摺り支持用ブラケット２と２２に支持された手摺り１は、上記した第１実施形態の要領でロックピン６を係止片８から外すと、右側のヒンジピン２３を中心に矢印Ｆのように回転することができる。図１０のようにほぼ垂直な姿勢にまで約９０°回転した手摺り１は、そのヒンジ板１９の長孔１８を利用して下ろされる（ヒンジピン２３を長孔１８の上端へ位置させる。）ことにより、同ヒンジ板１９は長孔１８の長さに相当するストローク分だけ、縦長矩形状で袋構造のヒンジ支持板２５の中空部内に挿入される。その結果、同手摺り１のヒンジ板１９の両側縁は、ヒンジ支持板２５の内外の側壁２５ａと２５ｂによって規制（拘束）されてほぼ垂直な姿勢を保持する。つまり、手摺り１は、取り敢えず前記垂直な姿勢を保持して退避状態となるので、出入り口開口Ａは全開となり、同出入り口開口Ａを通行する人にとって障害物はないことになる。勿論、用済み後は、再び手摺り１を元の水平状態にまで戻し、一側端部の嵌合板４を手摺り支持用ブラケット２の係止片８へ嵌めてロックピン６で止めた使用状態とすることができる。
【００３０】
次に図１１以下は、請求項３記載の発明の実施形態を示している。
本発明に係る出入り口横断用の着脱自在手摺りも、図９、図１０の実施形態と同様に、手摺り１を、出入り口開口Ａを水平方向に横断させて配置し、その一側端部の嵌合板４は、出入り口開口Ａの片側の建造物壁面Ｃへ固定した手摺り支持用ブラケット２の係止片８へ着脱自在に設置し、他側端部のヒンジ板１９は、他方の建造物壁面Ｃへ固定した手摺り支持用ブラケット２２のヒンジ支持板２５へヒンジピン２３により回転自在に連結して設置されている。
【００３１】
本実施形態の場合、手摺り１の一側端部に下向きのコ字形状溝を有する嵌合板４が設けられていると共に、図１２及び図１３に示すように、嵌合板４から外向きのフック部１７が設けられていることが特徴である。一方、同手摺り１の他側位置の前記手摺り支持用ブラケット２２の上方位置には、矢印Ｆ方向へ約９０°回転した手摺り１の仮止め用ブラケット２０が設置されている（図１１）。
【００３２】
この仮止め用ブラケット２０は、手摺り１の一側端部の嵌合板４が手摺り支持用ブラケット２の係止片８から取り外され、前記ヒンジピン２３を中心として図１１の矢印Ｆのように上方へ約９０°回転すると、同手摺り１の嵌合板４のフック部１７を掛け止め可能な仮止め具２７を有する。仮止め具２７は、図１３及び図１４で明らかなように、建造物壁面Ｃへ止めネジ５１で固定した取付板２６から前方へ突き出た平面視が矩形枠形状に構成されており、更に嵌合板４の行き止まり２７ａも設けられている。
【００３３】
手摺り１の嵌合板４に設けたフック部１７を仮止め用ブラケット２０の仮り止め具２７へ掛け止めるには、嵌合板４を係止片８から外してそのままヒンジピン２３を中心に上方へ約９０°回転させ、他側端部のヒンジ板１９の長孔１８の長さの限度に同手摺り１をそのまま降ろす。すると、フック部１７が仮止め具２７へ図１５Ａから図１５Ｂのように引っ掛かってぶら下がり、下端はヒンジピン２３で支持された仮止め状態（退避状態）となり、出入り口開口Ａは全開状態となる。この仮止め状態は、高齢者や身体障害者、或いは健常者が掴まり、多少ぶら下がるような使用状態でも、これに耐えるように嵌合板４や、フック部１７、仮止め用ブラケット２０及びその仮り止め具２７の強度設計を行う。
【００３４】
したがって、本実施形態の手摺り１も、一側端部の嵌合板４におけるロックピン６を内端寄りへ移動させる操作によって手摺り支持用ブラケット２の係止片８から取り外すことができ、他側端部のヒンジ板１９を止めたヒンジピン２３を中心に回転可能である。そして、上方へほぼ９０°回転した手摺り１は、その嵌合板４に設けたフック部１７を仮止め用ブラケット２０の仮り止め具２７へ掛け止めることができる。そして、この仮止め状態では、縦の手摺りとして使用することが可能である。あるいはまた、逆に前記嵌合板４を手摺り支持用ブラケット２の係止片８へ嵌めてロックピン６により止めた本来の使用状態に、所謂片手の操作で戻すことができる。
【００３５】
【発明の効果】
請求項１〜５に記載した発明に係る出入り口横断用の着脱自在手摺りは、手摺りの着脱操作を、少なくとも片手によって簡単、確実にできる。しかも手摺りを取り外したり回転して退避させた場合でも構成部品等が紛失する不具合は決して生じない。また、垂直な姿勢に仮止めした手摺りはそのまま縦の手摺りとしても使用可能である等々の効果を奏する。

A plate-shaped locking piece 8 is provided in which the U-shaped groove of the fitting plate 4 at both ends of the handrail 1 is fitted (the invention according to claim 4). As is clear from FIG. 3, the support plates 2 a of the handrail support bracket 2 are installed in such a manner as to regulate the tip positions of the fitting plates 4 at both ends of the handrail 1.
[0018]
The inwardly protruding dimension of the locking piece 8 of the handrail support bracket 2 moves within the elongated hole 5 in the fitting plate 4 of the handrail 1 as is apparent from the two-dot chain line in FIG. When the lock pin 6 is positioned near the inner end of the elongated hole 5, the size of the lock pin 6 can pass. Further, in the locking piece 8, the shape of the upper surface wall 4a of the U-shaped groove of the fitting plate 4 and the upper side portion 8a on which the lock pin 6 is placed is approximately 1/4 arc shape in the illustrated example. This means that the lock pin 6 is moved inward from the position of the support plate 2a (inward as viewed from the position of the left and right handrail support brackets 2 and 2 shown in FIG. 3) along the long hole 5. FIG. 9 shows an example of a shape suitable for moving to an end position. Therefore, the present invention is not limited to the above-described quarter-arc shape, but may be an inclined surface or the like that is appropriately lowered inward.
