Description

【０００１】
【発明の属する技術分野】
本発明は、足の不自由な人や、足腰の弱い老人などの被介助者を、ベッドと車椅子、車椅子と洋式トイレの便座、あるいは、車椅子どうし間で移動させるなどの場合に使用する移乗介助機に関する。
【０００２】
【従来の技術】
上述のような移乗介助機としては、従来、次のようなものが知られている。
すなわち、走行車輪付きの搭乗台に一体に支柱が設けられ、その支柱に膝パットが設けられている。
また、支柱に上下揺動可能に昇降アームが設けられるとともに、昇降アームに胸パットが設けられている。
更に、昇降アームの途中箇所に、被介助者の臀部から腰に回して支持するスリング（シート）を係止できるように構成されている。
【０００３】
上記構成により、例えば、ベッドから車椅子に被介助者を乗り移らせる場合を例にして説明すると、被介助者をベッドに腰掛けさせ、臀部や腰部の下方に回してスリング（シート）を当てがい、そのスリング（シート）を昇降アームに係止し、昇降アームを上昇させて吊り上げ、車椅子側に移動して車椅子に乗り移らせている。
【０００４】
【発明が解決しようとする課題】
しかしながら、上述のような従来例では、ベッドに腰掛けた被介助者の臀部や腰部の下方にスリング（シート）を当てがうときに、介助者が被介助者を抱き上げるようにしなければならず、介助者に大きな負担がかかる欠点があった。
【０００５】
また、トイレの中などで介助する場合に、スペースが狭くて介助作業が極めてしづらい欠点があった。
更に、被介助者にとっては、体を荷物のように吊り上げられ、品物と同じ扱いを受けているような感じになり、拒否感を抱く欠点があった。また、スリング（シート）を当てがった状態で移動する場合もあり、不格好な感じを抱き、同様に拒否感を抱く欠点があった。
【０００６】
本発明は、このような事情に鑑みて為されたものであって、請求項１および２に係る発明の移乗介助機は、乗り移りを容易に行えるようにすることを目的とし、請求項３に係る発明の移乗介助機は、乗り移りを円滑に行えるようにすることを目的とし、請求項４に係る発明の移乗介助機は、車椅子と便器との間での乗り移りを容易に行えるようにすることを目的とし、請求項５に係る発明の移乗介助機は、乗り移りを良好に行えるとともに被介助者を機体本体側に乗り移らせた後での移動を安全に行えるようにすることを目的とする。また、請求項６に係る発明の移乗介助機は、被介助者を機体本体側に乗り移らせた後での移動を安全に行えるようにすることを目的とする。
【０００７】
【課題を解決するための手段】
請求項１に係る発明の移乗介助機は、上述のような目的を達成するために、
機体本体に、水平方向に突出する片持ち状態で被介助者を搭乗支持する支持部材を設け、前記支持部材の先端と基端とにわたり、被介助者の臀部と接触した状態においてその接触位置を相対的に移動させずに臀部との接触面積を拡縮しながら水平方向に移動可能に、腰掛け姿勢の被介助者の臀部を載せる幅を有する無端ベルトを巻き掛け、前記無端ベルトの上方箇所に位置させて、被介助者が持つ手すりを前記無端ベルトと同じ水平方向に移動可能に設けて構成する。
ここでいう被介助者とは、足の不自由な人や、足腰の弱い老人などのことを総称する。
【０００８】
（作用・効果）請求項１に係る発明の移乗介助機の構成によれば、ベッドや車椅子や便器などの他部に腰掛け姿勢で座っている被介助者に臀部の前側を少し浮かせてもらい、そこに無端ベルトの先端を進入して潜りこませ、無端ベルトを移動することにより臀部の後側の下方まで抵抗無く進入させ、被介助者を支持部材に搭乗支持させることができる。
そのうえ、被介助者が手すりを持った状態で、無端ベルトと同じように移動しながら乗り移りを行うことができる。
このため、介助者が被介助者を抱き上げたりしなくても、被介助者を支持部材に搭乗支持できるから、被介助者の乗り移りを容易に行える。近年では老齢化が進み、非力な老人が介助者として介護にあたることも多く、極めて有用である。
そのうえ、介助者が体を支えていなくても、被介助者が臀部に追随する状態で体全体を移動でき、乗り移りを一層容易に行える。また、被介助者を機体本体側に乗り移らせた後での移動を安定感のある状態で安全に行える。移動の際に被介助者を支えていなくても良いから、介助者が非力な場合に、特に有用である。
【０００９】
請求項２に係る発明の移乗介助機は、前述のような目的を達成するために、
機体本体に、水平方向に突出する片持ち状態で被介助者を搭乗支持する支持部材を設け、前記支持部材の先端と基端とにわたり、被介助者の臀部と接触した状態においてその接触位置を相対的に移動させずに臀部との接触面積を拡縮しながら水平方向に移動可能に、腰掛け姿勢の被介助者の臀部を載せる幅を有する無端ベルトを巻き掛け、前記支持部材の下方の先端と基端とにわたり、足を載置可能な足載置用無端ベルトを巻き掛けて構成する。
（作用・効果）請求項２に係る発明の移乗介助機の構成によれば、ベッドや車椅子や便器などの他部に腰掛け姿勢で座っている被介助者に臀部の前側を少し浮かせてもらい、そこに無端ベルトの先端を進入して潜りこませ、無端ベルトを移動することにより臀部の後側の下方まで抵抗無く進入させ、被介助者を支持部材に搭乗支持させることができる。
そのうえ、被介助者が足載置用無端ベルトに足を乗せた状態で、無端ベルトと同じように移動しながら乗り移りを行うことができる。
このため、介助者が被介助者を抱き上げたりしなくても、被介助者を支持部材に搭乗支持できるから、被介助者の乗り移りを容易に行える。近年では老齢化が進み、非力な老人が介助者として介護にあたることも多く、極めて有用である。
そのうえ、被介助者の足が宙に浮いた状態にならずに体全体を移動でき、安定感のある状態で、乗り移りを一層容易に行える。また、被介助者を機体本体側に乗り移らせた後での移動を安定感のある状態で安全に行える。
また、請求項３に係る発明の移乗介助機は、前述のような目的を達成するために、
請求項１または２に記載の移乗介助機において、
支持部材の下方に従動用支持部材を設け、前記従動用支持部材の先端と基端とにわたり、被介助者の臀部と乗り移る前に接触していたかまたは乗り移り後に接触する他部と接触した状態においてその接触位置を相対的に移動させずに他部との接触面積を拡縮しながら無端ベルトと同じ水平方向に移動可能に、従動用無端ベルトを巻き掛けて構成する。
【００１０】
（作用・効果）請求項３に係る発明の移乗介助機の構成によれば、無端ベルトの移動に伴い、ベッド上のシーツや車椅子の座席シートや便器の便座などの他部に従動用無端ベルトの下向き面が接触し、他部との間での接触に伴う抵抗を受けることなく従動用無端ベルトを進入させ、被介助者を支持部材に搭乗支持させることができる。
このため、無端ベルトがベッド上のシーツを巻き込むとか、車椅子の座席シートや便器の便座などの他部に接触して突っ張るといったことなく、支持部材を円滑に移動でき、介助者が被介助者を抱き上げたりしなくても、被介助者を支持部材に搭乗支持できるから、被介助者の乗り移りを円滑に行える。
【００１１】
請求項４に係る発明の移乗介助機は、前述のような目的を達成するために、
請求項１ないし３に記載の移乗介助機において、
機体本体に走行可能に走行車輪を設け、無端ベルトの下方箇所に位置させて、前記機体本体に、先端に機体支持輪体を備えた機体支持フレームを一対設け、前記機体支持フレームの先端側の間隔を、車椅子の左右車輪間に進入可能な縮み状態と、便器を挟む拡がり状態とに変更可能に構成する。
【００１２】
（作用・効果）請求項４に係る発明の移乗介助機の構成によれば、洋式トイレの便器の設置側部分の幅が車椅子の左右車輪の内側間隔よりもやや広いくても、車椅子との間で乗り移りを行うときには、機体支持フレームの先端側の間隔を縮めた状態で左右車輪間に進入することができ、一方、洋式トイレの便器との間で乗り移りを行うときには、機体支持フレームの先端側の間隔を拡がって便器を挟む状態で進入することができる。
このため、車椅子と便器との間での乗り移りを行うときに、車椅子および便器のいずれに対しても機体本体を接近させることができ、移乗介助機を介しての車椅子と便器との間での乗り移りを容易に行える。
【００１３】
請求項５に係る発明の移乗介助機は、前述のような目的を達成するために、
請求項１ないし４のいずれかに記載の移乗介助機において、
支持部材を対地的に昇降可能に設け、無端ベルト上に載せた被介助者の臀部の載置レベルを変更可能に構成する。
【００１４】
（作用・効果）請求項５に係る発明の移乗介助機の構成によれば、乗り移りの際には、ベッドや車椅子や便器の便座などの他部の高さに合うように、被介助者が搭乗する無端ベルトの高さを調整することができる。また、被介助者を機体本体側に乗り移らせた後で移動する際には、被介助者の体格などに合わせて移動しやすい高さに調整することができる。
このため、ベッドや車椅子や便器の便座などの他部の高さの違いにかかわらず、乗り移りを良好に行うことができ、また、被介助者を機体本体側に乗り移らせた後での移動を安全に行える。
【００１５】
【００１６】
【００１７】
【００１８】
【００１９】
請求項６に係る発明の移乗介助機は、前述のような目的を達成するために、
請求項１ないし５のいずれかに記載の移乗介助機において、
無端ベルト上に乗り移らされた被介助者の背中をもたれさせる背もたれを、被介助者の背後に位置させる使用姿勢と被介助者の背後から退避した不使用姿勢とに姿勢変更可能に設けて構成する。
【００２０】
（作用・効果）請求項６に係る発明の移乗介助機の構成によれば、被介助者をベッドや車椅子や便器の便座などの他部との間で乗り移らせるときには、その介助作業に邪魔にならない不使用姿勢に背もたれを退避しておき、被介助者を機体本体側に乗り移らせた後には、被介助者の背中をもたれさせる使用姿勢に変更し、被介助者の背中を背もたれにもたれさせた状態で機体本体を移動することができる。
このため、被介助者を機体本体側に乗り移らせた後での移動を、被介助者の体を背もたれに支持させた状態で安全に行える。移動の際に被介助者を支えていなくても良いから、一人の介助者でも容易に移動でき、極めて有用である。
【００２１】
【発明の実施の形態】
次に、本発明の移乗介助機の実施例を図面に基づいて詳述する。
【００２２】
図１は、本発明に係る移乗介助機の基本構成例を示す全体斜視図、図２は全体側面図であり、一対のキャスター式の走行車輪１と操向ハンドル２とを備えた機体本体３に、水平方向に突出する片持ち状態で被介助者ＨＵを搭乗支持する支持部材４が設けられ、移乗介助機５が構成されている。
【００２３】
図３の側面図、および、図４の要部の斜視図に示すように、支持部材４が鋼板で構成され、その基端側で機体本体３の左右側板６，６に溶接などによって一体連接されている。
左右側板６，６に、電動モータ（図示せず）を内蔵した主動ローラ７と、２個の第１の遊転ローラ８，８が回転可能に設けられている。支持部材４の先端側に断面形状円形の第１の丸鋼９が溶接などにより一体連接されている。
【００２４】
主動ローラ７と、第１の遊転ローラ８，８と支持部材４と第１の丸鋼９とにわたり、腰掛け姿勢の被介助者ＨＵの臀部Ｈを載せる幅を有する無端ベルト１０が巻き掛けられている。支持部材４および第１の丸鋼９の外表面、ならびに、無端ベルト１０の内周面は、いずれも接触抵抗が小さくなるように滑りやすいようになっている。
【００２５】
上記構成により、主動ローラ７を緩い速度で回転させ、被介助者ＨＵの臀部Ｈと接触した状態においてその接触位置を相対的に移動させずに臀部Ｈとの接触面積を拡縮しながら無端ベルト１０が水平方向に移動し、臀部Ｈと無端ベルト１０との間での接触抵抗が無い状態で、臀部Ｈと、ベッド上のシーツや車椅子の座席シートや便器の便座などの他部Ｂとの間に、無端ベルト１０を進入できるようになっている。
【００２６】
支持部材４の下方に、支持部材４と平行になる状態で鋼板製の従動用支持部材１１が設けられるとともに、その従動用支持部材１１が基端側で機体本体３の左右側板６，６に溶接などによって一体連接されている。
左右側板６，６に、２個の第２の遊転ローラ１２，１２が回転可能に設けられている。従動用支持部材１１の先端側に断面形状円形の第２の丸鋼１３が溶接などにより一体連接されている。
【００２７】
第２の遊転ローラ１２，１２と第２の丸鋼１３とにわたり、無端ベルト１０と同じ幅の従動用無端ベルト１４が巻き掛けられている。従動用支持部材１１および第２の丸鋼１３の外表面、ならびに、従動用無端ベルト１４の内周面は、いずれも接触抵抗が小さくなるように滑りやすいようになっている。
【００２８】
上記構成により、車椅子やベッドや便器などに乗り移る前に被介助者ＨＵの臀部Ｈと接触していた他部Ｂと接触した状態においてその接触位置を相対的に移動させずに他部Ｂとの接触面積を拡縮しながら、従動用無端ベルト１４を無端ベルト１０と同じ水平方向に移動し、他部Ｂと従動用無端ベルト１４との間での接触抵抗が無い状態で、臀部Ｈと、ベッド上のシーツや車椅子の座席シートや便器の便座などの他部Ｂとの間に、無端ベルト１０と共に従動用無端ベルト１４を進入できるようになっている。
【００２９】
図５の要部の平面図に示すように、無端ベルト１０の下方箇所に位置させて、機体本体３に、先端にキャスター式の機体支持輪体１５を備えた機体支持フレーム１６が一対設けられている。機体支持フレーム１６の基端側が鉛直方向の軸芯周りで回転可能に設けられている。
【００３０】
機体本体３に、機体支持フレーム１６に当接するストッパー１７が一体連接されるとともに、機体支持フレーム１６と機体本体３とにわたって巻きバネ１８が設けられ、機体支持フレーム１６の先端側の間隔を、ストッパー１７が機体支持フレーム１６に当接して両機体支持フレーム１６が互いに平行な姿勢になって、車椅子Ｂ１の左右車輪１９，１９間に進入可能な縮み状態と、両機体支持フレーム１６が先拡がりの姿勢になって、便器Ｂ２を挟む拡がり状態とに変更可能に構成されている。図中１６ａは、後述する便器Ｂ２などと当たった際に両機体支持フレーム１６を拡がりやすくするためのガイド輪体を示している。このガイド輪体１６ａは無くても良い。その場合は、両機体支持フレーム１６の対向する部分の先端側をテーパ面や曲面に形成しておくのが好ましい。
【００３１】
上記構成により、図６の動作説明に供する平面図に示すように、被介助者ＨＵを移乗介助機５に搭乗させて洋式トイレ２０内に走行するときには、車椅子Ｂ１の左右車輪１９，１９間に進入して被介助者ＨＵを乗り移らせたときの縮み状態になっている［図６の（ａ）］。
【００３２】
その縮み状態で走行して機体支持輪体１５が便器Ｂ２に当たるに伴い、巻きバネ１８の付勢力に抗して両機体支持フレーム１６が先拡がりの姿勢になって便器Ｂ２を挟み、被介助者ＨＵを便座の上方まで移動させ［図６の（ｂ）］、その状態で無端ベルト１０を駆動移動して抜き出し、被介助者ＨＵを便座に乗り移すことができるようになっている。
【００３３】
操向ハンドル２の下方箇所において、機体本体３に足踏み板２１が設けられ、方向転換するときや段差を乗り越えるときなどに、機体本体３を容易に傾けられるように構成されている。
【００３４】
図２に示すように、機体本体３の支持部材４側のフレーム３ａと走行車輪１側のフレーム３ｂとが平行４連リンク機構２２と昇降用アクチュエータ２３とを介して連動連結され、図７の動作説明に供する概略側面図に示すように、下位位置［図７の（ａ）］、中間位置［図７の（ｂ）］および上位位置［図７の（ｃ）］と、支持部材４を対地的に昇降し、無端ベルト１０上に載せた被介助者ＨＵの臀部Ｈの載置レベルを変更できるように構成されている。
図中２４は、搭乗状態で被介助者ＨＵが持つ支持ハンドルを示している。
【００３５】
上記構成により、乗り移りの際には、ベッドや車椅子や便器の便座などの他部Ｂの高さに合うように、被介助者ＨＵが搭乗する無端ベルト１０の高さを調整し、乗り移りを良好に行うことができるようになっている。また、被介助者ＨＵを機体本体３側に乗り移らせた後で移動する際には、被介助者ＨＵの体格などに合わせて移動しやすい高さに調整し、被介助者ＨＵを機体本体３側に乗り移らせた後での移動を安全に行えるようになっている。
【００３６】
上記基本構成例の移乗介助機５によれば、図８の側面図に示すように、高さを合わせた後に無端ベルト１０を正転駆動し、無端ベルト１０および従動用無端ベルト１４を、ベッドＢに腰掛けた被介助者ＨＵの臀部ＨとベッドＢとの間に潜り込ませ、臀部ＨやベッドＢ上のシーツなどとの間で接触抵抗を受けることなく、被介助者ＨＵを無端ベルト１０上に搭乗させることができる。
【００３７】
また、無端ベルト１０上に搭乗させた状態で被介助者ＨＵをベッドＢ上まで移動させ、高さを合わせた後に無端ベルト１０を逆転駆動し、無端ベルト１０および従動用無端ベルト１４を、ベッドＢに腰掛けた被介助者ＨＵの臀部ＨとベッドＢとの間から、臀部ＨやベッドＢ上のシーツなどとの間で接触抵抗を受けることなく抜き出し、被介助者ＨＵをベッドＢ上に乗り移らせることができる。
このようにして、ベッドＢとの間での被介助者ＨＵの乗り移りを行う。
【００３８】
同様にして、図９の斜視図に示すように、車椅子Ｂ１の座席シートとの間で接触抵抗を受けることなく、車椅子Ｂ１との間での被介助者ＨＵの乗り移りを行う。また、図１０の斜視図に示すように、便座との間で接触抵抗を受けることなく、便器Ｂ２との間での被介助者ＨＵの乗り移りを行う。図１０においては、わかりやすくするために、両機体支持フレーム１６を先拡がりの姿勢で示している。これらにより、ベッドＢと車椅子Ｂ１、ベッドＢと便器Ｂ２、車椅子Ｂ１と便器Ｂ２、ならびに、車椅子Ｂ１どうしなどにおいて、移乗介助機５を介して、被介助者ＨＵを容易に乗り移らせることができる。
【００３９】
図１１は、本発明に係る移乗介助機の第１実施例を示す要部の側面図、図１２は要部の一部切欠平面図であり、基本構成例と異なるところは次の通りである。 すなわち、機体本体３に、無端ベルト１０の上方箇所に位置させて、前方に突出する片持ち状態でアングル状の手すりフレーム３１が一体連接され、その手すりフレーム３１に回転自在に３個の遊転ローラ３２が設けられ、それらの遊転ローラ３２にわたって、無端ベルト１０と同じ水平方向に移動するように、手すり用無端ベルト３３が巻き掛けられ、無端ベルト１０の上方で、被介助者ＨＵが持つ手すり３４が構成されている。他の構成は基本構成例と同じであり、同一図番を付してその説明は省略する。
【００４０】
この第１実施例によれば、乗り移りに際して、無端ベルト１０上に搭乗するとか無端ベルト１０上から降りるために被介助者ＨＵが無端ベルト１０上で移動するときに手すり３４を持ち、乗り移りを安定した状態で行える。
手すり用無端ベルト３３としては、無端ベルト１０と同調して駆動移動するように構成しても良い。また、手すり３４を伸縮可能な多段式のエアシリンダで構成しても良い。
【００４１】
図１３は、本発明に係る移乗介助機の第２実施例を示す要部の側面図、図１４は要部の平面図であり、基本構成例と異なるところは次の通りである。
すなわち、一対の機体支持フレーム１６それぞれの前後両端それぞれに支持ブラケット４１が立設されるとともに、支持ブラケット４１に遊転ローラ４２が設けられ、それらの遊転ローラ４２にわたって、無端ベルト１０と同じ水平方向に移動するように、足載置用無端ベルト４３が巻き掛けられている。他の構成は基本構成例と同じであり、同一図番を付してその説明は省略する。
【００４２】
この第２実施例によれば、乗り移りに際して、無端ベルト１０上に搭乗するとか無端ベルト１０上から降りるために被介助者ＨＵが無端ベルト１０上で移動するときに足を足載置用無端ベルト４３上に乗せ、乗り移りを安定した状態で行える。
足載置用無端ベルト４３としては、無端ベルト１０と同調して駆動移動するように構成しても良い。
【００４３】
図１５は、本発明に係る移乗介助機の第３実施例を示す要部の斜視図であり、基本構成例と異なるところは次の通りである。
すなわち、支持ハンドル２４の一端側が延長され、そこに手すり５１と背もたれ５２とが形成されている。
【００４４】
機体本体３に、水平方向の軸芯周りで回転可能に支持ハンドル２４が取り付けられ、機体本体３と支持ハンドル２４とが、伸長側に付勢されるとともに通気孔（図示せず）の開閉によって任意の長さで停止する、いわゆるガススプリング５３を介して連結されている。
【００４５】
この構成により、背もたれ５２を回転させ、無端ベルト１０上に乗り移らされた被介助者ＨＵの背後に位置させる使用姿勢と被介助者ＨＵの背後から退避した不使用姿勢とに姿勢変更できるように構成されている。他の構成は基本構成例と同じであり、同一図番を付してその説明は省略する。
【００４６】
この第３実施例によれば、被介助者ＨＵをベッドや車椅子や便器の便座などの他部Ｂとの間で乗り移らせるときには、その介助作業の邪魔にならない上方の不使用姿勢に背もたれ５２を退避しておき、被介助者ＨＵを機体本体３側に乗り移らせた後には、被介助者ＨＵの背中をもたれさせる使用姿勢に変更し、被介助者ＨＵの体を背もたれ５２に支持させるとともに片側の手で手すり５１を持った状態で安全に移動することができる。
【００４７】
上記第３実施例では、片側にのみ手すり５１を形成しているが、全体をループ状に形成し、両側の手すりと背もたれを備えさせるように構成しても良い。
【００４８】
上記実施例では、機体本体３を手押し式に構成しているが、例えば、走行モータを設けて自走式に構成しても良い。また、走行車体に構成せずに、例えば、機体本体３を鉛直方向の支軸周りで回転可能に構成し、その回転によって、ベッドＢと車椅子Ｂ１との間で乗り移れるように構成するものでも良い。
【００４９】
また、上記実施例では、支持部材４を対地的に昇降するのに、平行４連リンク機構２２を設けているが、平行４連リンク機構２２に代えて十字状にリンクを連結したパンタグラフ式の昇降構成を採用しても良い。詳述すれば、十字状に連結したリンクの一方の一端側を機体本体３の支持部材４側のフレーム３ａに連結し、他方のリンクの一端側を走行車輪１側のフレーム３ｂに連結し、両リンクの他端側の一方を水平方向に駆動移動するように構成する。

【発明の効果】
以上説明したように、請求項１に係る発明の移乗介助機によれば、ベッドや車椅子や便器などの他部に腰掛け姿勢で座っている被介助者に臀部の前側を少し浮かせてもらい、そこに無端ベルトの先端を進入して潜りこませ、無端ベルトを移動することにより臀部の後側の下方まで抵抗無く進入させ、被介助者を支持部材に搭乗支持させることができる。
そのうえ、被介助者が手すりを持った状態で、無端ベルトと同じように移動しながら乗り移りを行うことができる。
このため、介助者が被介助者を抱き上げたりしなくても、被介助者を支持部材に搭乗支持できるから、被介助者の乗り移りを容易に行える。近年では老齢化が進み、非力な老人が介助者として介護にあたることも多く、極めて有用である。
そのうえ、介助者が体を支えていなくても、被介助者が臀部に追随する状態で体全体を移動でき、乗り移りを一層容易に行える。また、被介助者を機体本体側に乗り移らせた後での移動を安定感のある状態で安全に行える。移動の際に被介助者を支えていなくても良いから、介助者が非力な場合に、特に有用である。
