Description

【０００１】
【発明の属する技術分野】
本発明は、身体障害者や養護老人等の入浴に供される昇降式搬送車に関する。
【０００２】
【従来の技術】
従来技術の実開昭５０−３０５９２号公報には、キャスター、下部フレ−ム、昇降装置、レール、上部フレ−ム、載置部、導入部、側面板、枠部材、ローラー、担架、ストッパー等からなる「医療用担架搬送車」が開示されている。
【０００３】
【発明が解決しようとする課題】
前記従来装置は、載置した担架を昇降させることができるものであるが、中央に介助者が入れる空間部が無い。従来装置は担架の高さ調節はできるが、介助者が入る空間部が無いので、並置した浴槽等へ担架を移乗させる操作は容易にできないものであった。
【０００４】
又、搬送車を入浴に使用する場合、入浴中の入浴者の介護又は看視は、搬送車を除去移動させなければできず、搬送車の操作に多くの手数が掛かり、不都合であった。
【０００５】
又、搬送車を除去移動せずそのままの位置で、介助者が、入浴中の入浴者の介護又は看視できる装置が要望されていた。更に、従来装置では、浴槽内の入浴者の介助は浴槽縁が高いため容易ではなかったので、踏み台等に上がったやや高い位置から容易に行き届いた入浴介助できる装置が要望されていた。
【０００６】
本発明の目的は、上記課題を解決したものであり、手動で容易に載置物を昇降操作、介助作業及び移乗操作できる昇降式搬送車を提供することにある。
【０００７】
【課題を解決しようとする手段】
即ち本発明は、上方に担架載せ部（４）が設けられる平面視略長方形状の搬送車（１）にはその長手方向の略中央部に介助者が出入りできる幅の前記搬送車（１）の一方側長辺から他方側長辺を横断する空間部（５）が設けられており、該空間部（５）の外方であって前記搬送車（１）の長手方向両側には前記担架載せ部（４）の一方側及び他方側をそれぞれ昇降させる昇降機（３）が配設され、介助者は前記搬送車（１）を浴槽に並置した後、前記空間部（５）内に入り込んで前記搬送車（１）と前記浴槽間における担架の移乗操作及び前記浴槽上へ移乗された前記担架上に臥す入浴者への介助作業が行える昇降式搬送車である。又、前記搬送車（１）の長手方向両側に配設される各昇降機（３）に駆動源（１１）が設けられている。更に、前記駆動源（１１）は、連動手段（４０）に連結されて連動し、該連動手段（４０）は、前記駆動源（１１）の駆動量を補正する補正機能を有する。更に又、前記補正機能は、前記駆動源（１１）の延出位置又は角度、又は、前記担架載せ部（４）の位置又は角度を検出する検出器（３１）を有し、該検出器（３１）は、前記駆動源（１１）の延出位置を検出する駆動源位置検出器（６２）であり、又は、前記担架載せ部（４）の位置を検出する担架載せ部位置検出器（６３）であり、又は、前記駆動源（１１）の角度を検出する駆動源角度検出器（６４）であり、又は、前記担架載せ部（４）の角度を検出する担架載せ部角度検出器（６５）である。又、昇降機（３）は、速度制御器（３０）で昇降速度が制御される。更に、前記担架載せ部（４）の昇降の開始直後に昇降速度は漸増し、所定の速度に至って昇降し、停止にかけて昇降速度を漸減し停止に至るように、前記昇降機（３）が制御される。更に又、前記担架載せ部（４）に垂下状に軸支されて空間部（５）にある可動水受盤（２１）は、回動させて水平状に係止することが可能であり、更に、垂下状にある前記可動水受盤（２１）が、前記担架載せ部（４）と共に下降する時、当該下降事象を感知した前記可動水受盤（２１）は、水平方向に回動し又は上方向に移動し又は前記可動水受盤（２１）自体が収縮する。又、昇降機（３）及び昇降機（３）を動かす駆動源（１１）が１個である。更に、前記昇降機（３）を動かす前記駆動源（１１）が１個である。更に又、上方に担架載せ部（４）が設けられる平面視略長方形状の搬送車（１）にはその長手方向の略中央部に介助者が出入りできる幅の前記搬送車（１）の一方側長辺から他方側長辺を横断する空間部（５）が設けられており、該空間部（５）の外方であって前記搬送車（１）の長手方向両側には前記担架載せ部（４）の一方側及び他方側を昇降させる前記駆動源（１１）がそれぞれ配設され、介助者は前記搬送車（１）を浴槽に並置した後、前記空間部（５）内に入り込んで前記搬送車（１）と前記浴槽間における担架の移乗操作及び前記浴槽上へ移乗された前記担架上に臥す入浴者への介助作業が行えることを特徴とする昇降式搬送車である。
【０００８】
【発明の実施の形態】
本発明の搬送車１を入浴に用いる場合、搬送車１を浴槽（図示省略）に横着けし、搬送車１上の担架（図示省略）を前記浴槽の上に移動させ、前記浴槽を上昇させ、前記担架上の入浴者を入浴させる。
【０００９】
担架３を浴槽１に移乗させる時、搬送車１の略中央部に設けられた空間部５に介助者が入り、操作容易に、前記担架を搬送車１から前記浴槽に入れ、又、前記浴槽から搬送車１へ引き戻す。搬送車１に設けらた昇降機３は、載置した患者を昇降させる。
【００１０】
搬送車１に設けられた複数個の昇降機３は、各昇降機３に設けられる駆動源１１により作動する。
【００１１】
複数個の駆動源１１は、連動手段４０に連結されて連動する。連動手段４０が擁する補正機能２８は、駆動源１１の駆動量を補正する。
【００１２】
補正機能２８が有する検出器３１は、駆動源１１の延出位置（＝ストローク）又は角度、又は、担架載せ部４の位置又は角度を検出する。検出器３１が有する駆動源位置検出器６２は、駆動源１１の延出位置を検出する。検出器３１が有する担架載せ部位置検出器６３は、担架載せ部４の位置を検出する。
【００１３】
検出器３１が有する駆動源角度検出器６４は、駆動源１１の角度を検出する。検出器３１が有する担架載せ部角度検出器６５は、担架載せ部４の角度を検出する。
【００１４】
速度制御器３０は、昇降機３の昇降速度を制御する。
【００１５】
速度制御器３０は、担架載せ部４の移動の開始直後に速度は漸増し、所定の速度に至って昇降し、停止の暫時前は速度を漸減し停止に至るように、昇降機３を制御する。
【００１６】
台車部２は、昇降機３と担架載せ部４を載設する。担架載せ部４は、可動水受盤２１を垂下状に軸支する。
【００１７】
可動水受盤２１は、回動して水平状に係止可能である。又、水受けに供しない時には垂下状にしておりこの時の垂下状にある可動水受盤２１は、担架載せ部４と共に下降させると、台車部２に当たって回動し、担架載せ部４の下降を妨げない。又は、垂下状にある可動水受盤２１は台車部２に当たって収縮し担架載せ部４の下降を妨げない。
【００１８】
台車部２に載設される昇降機３は１個の駆動源１１で昇降する。或いは、昇降機３は複数の昇降機３でなり、これらの昇降機３は１個の駆動源１１で作動する。搬送車１に設けらた駆動源１１は、載置した患者を昇降させる。
【００１９】
【実施例】
図１乃至３に示す本発明の第１実施例に係る搬送車１は、台車部２と、台車部２上に載設される昇降機３と、昇降機３上に載設され担架載せ部４とからなる。搬送車１の長手方向（＝前後方向）における略中央部には、左右が開口され、介助者が搬送車１中に出入りできる空間部５が設けられる。空間部５の他の参考例では、空間部５の左右のいずれか一方が開口される。
【００２０】
更に、搬送車１を移動させる時に掴む前・後取っ手６・７と、搬送車１の下部に設けられ搬送車１を床面に容易に走行させるキャスタ−８とからなる。キャスタ−８はストッパー（図示省略）付きである。
【００２１】
前記台車部２にあって空間部５の下部位置に、介助者が上る踏み台１４が設けられる。
【００２２】
前記昇降機３は、搬送車１の前方に前昇降機９と、後方に後昇降機１０とからなる。
【００２３】
前昇降機９と後昇降機１０の各昇降機３に駆動源１１が設けらる。駆動源１１は具体的には電動アクチェーターである。前・後昇降機９・１０に係る前・後駆動源１２・１３は、連動手段４０に連結される。
【００２４】
前記担架載せ部４は、搬送車１の前方に前担架載せ部１５と、後方に後担架載せ部１６とからなる。
【００２５】
入浴に用いた場合に前記担架からの落下水を受け止める水受盤１８が、担架載せ部４に載設される。即ち、前担架載せ部１５に前水受盤１９が載設され、後担架載せ部１６に後水受盤２０が載設される。
【００２６】
空間部５には可動の可動水受盤２１が設けられ、該可動水受盤２１は、前後に二分されており、前担架載せ部１５に前可動水受盤２２が垂下状に軸４６（図２参照）で軸支され、後担架載せ部１６に後可動水受盤２３が垂下状に軸４６で軸支される。
【００２７】
前・後可動水受盤２２・２３は、水平位置と垂下状位置との間を回動・固定可能に設けられる。即ち、垂下状位置にある前・後可動水受盤２２・２３を水平位置に回動させると、前・後可動水受盤２２・２３は水平位置に、引っ張りバネ２４の収縮力により固定する。
【００２８】
水平位置にある前・後可動水受盤２２・２３を垂下状位置に回動させると、前・後可動水受盤２２・２３は垂下位置に、引っ張りバネ２４の収縮力により固定する。
【００２９】
図３に電気的構成をブロック図で示している。上昇・下降・緊急停止操作部２５・２６・２７は、駆動源１１を伸縮作動に上昇、下降、緊急停止の指示を与えるものである。
【００３０】
駆動源１１を連動させる連動手段４０は、駆動源１１の駆動量を補正する補正機能２８と、駆動源１１の駆動を制御する駆動源制御器２９と、駆動源１１の駆動速度を制御する速度制御器３０とを有する。
【００３１】
補正機能２８は、駆動源１１又は担架載せ部４の移動状態を検出する検出器３１と、検出器３１の出力を比較する比較器４１とを有する。具体的には、前・後駆動源１２・１３に添設され該駆動源１２・１３の延出位置を検出する駆動源位置検出器６２（＝前・後駆動源位置検出器３２・３３）であり、前記比較器４１は前・後駆動源位置検出器３２・３３の二出力値を比較しそれらの値が同値になるよう駆動源制御器２９を介して前・後駆動源１２・１３を駆動させる。
【００３２】
速度制御器３０は、担架載せ部４の移動の開始直後に速度は漸増し、所定の速度に至って昇降し、停止の暫時前は速度を漸減し停止に至るように、昇降機３を制御する前・後漸増漸減制御器３４・３５を有する。更に、前・後漸増漸減制御器３４・３５は、前記担架載せ部４の移動の開始時に漸増後は一定速度で昇降するように、昇降機３を制御するものである。
【００３３】
上限・下限前検出器３７・３８及び上限・下限後検出器４４・４５は、前・後駆動源１２・１３のそれぞれの延出端及び収縮端を検出するもので、上限・下限前検出器３７・３８及び上限・下限後検出器４４・４５が作動すると前・後駆動源１２・１３が漸減停止する。
【００３４】
尚、図１中、１７は前記担架を支持するレ−ル、２５は、担架載せ部４が上昇するように駆動源１１を駆動させる上昇操作部、２６は、担架載せ部４が上昇するように駆動源１１を駆動させる下降操作部、２７は、担架載せ部４が緊急停止するように駆動源１１の駆動を停止させる緊急停止操作部、３９はペダル、４２は４個のキャスター８に同時にロックを掛け或いは解除するために前記ストッパーを連結するストッパー連結具、６９は電源、７２は電源収納部である。
【００３５】
第１実施例の使用状態を述べる。第１実施例を入浴に使用する例では、介助者は、入浴者及び前記担架を載せた搬送車１を所定位置へ移動させた後、ペダル３９を踏んで、キャスタ−８をロックする。
【００３６】
次に、上昇・下降操作部２５・２６を操作して搬送車１を昇降させ、適する高さに至らせる。例えば、介助者は、搬送車１を昇降調整し入浴者を洗浄に適する高さに至らせ、前記担架上の入浴者洗浄する。
【００３７】
或いは、浴槽（図示省略）上縁面と同高に至らせ、介助者は適宜踏み台１４に上がり楽な姿勢で、前記担架を前記浴槽真上へ移乗させる。移乗後、介助者は、浴槽上又は浴槽内にいる入浴者を介助する。
【００３８】
搬送車１に設けられた前・後昇降機９・１０は、各昇降機９・１０に設けられる駆動源１１により作動し、入浴者を昇降させる。上昇・下降操作部２５・２６は、上昇又は下降を指示し、駆動源１１を伸・縮させる。
【００３９】
複数個の駆動源１１は、連動手段４０に連結されて連動する。連動手段４０が擁する補正機能２８は、駆動源１１の駆動量即ちストロークの変化量を補正する。補正機能２８により、前・後担架載せ部１５・１６は均衡して昇降する。補正機能２８が有する前・後駆動源位置検出器３２・３３は、前・後駆動源１２・１３のそれぞれストロークを検出する。
【００４０】
比較器４１は、前・後駆動源位置検出器３２・３３の両値を比較し、両値が異なると、出力を発し、駆動源制御器２９を介して前・後駆動源１２・１３を適宜過大又は過小駆動し、前記両値が同じ値になるように作動させ、補正の機能を為す。
【００４１】
速度制御器３０は、昇降機３の昇降速度を制御する。速度制御器３０の前・後漸増漸減制御器３４・３５は、担架載せ部４の移動の開始直後に速度は漸増し、所定の速度に至って一定速度で昇降し、停止の暫時前は速度を漸減し停止に至るように、昇降機３を制御する。
【００４２】
即ち、担架載せ部４の昇降は、前・後漸増漸減制御器３４・３５が作動し、スロースタート及びスローストップする。更に、前・後漸増漸減制御器３４・３５は担架載せ部４の移動の開始直後に速度を漸増させ、所定の速度に至った時一定速度で昇降するように駆動源１１を制御する。
【００４３】
例えば、電源６９が低下し（＝電源情報）、電流パルスの振幅が下がった時は、前・後漸増漸減制御器３４・３５により電流パルスのパルス幅を増して、駆動源１１を一定速度に駆動する。又、昇降機３の機械的特性に起因して昇降速度が高さ位置ごとに異なる場合はその機械的特性（＝機械情報）に対応して電流パルスのパルス幅を増減変化させて担架載せ部４が一定速度で昇降するように駆動源１１を制御する。上述の電源情報や機械情報を駆動源制御器２９に記憶させている。
【００４４】
前・後駆動源１１の移動の上・下端では、上・下限前検出器３７・３８及び上・下限後検出器４４・４５が作動しスローストップする。
【００４５】担架載せ部４に垂下状に軸支された前・後可動水受盤２２・２３は、回動して水平状に、引っ張りバネ２４の引っ張り作用により係止可能である。
【００４６】
又、垂下状にした前・後可動水受盤２２・２３は、担架載せ部４と共に下降する時、該前・後可動水受盤２２・２３が直接にその下端が台車部２に当たって、軸４６を中心に水平方向へ回動し、傾斜面を呈するようになる。この回動により前・後可動水受盤２２・２３は、担架載せ部４の下降を妨げることを回避する。
【００４７】
図４に示す本発明の第２実施例は、第１実施例における前駆動源１２を除去し、後昇降機９と前昇降機１０を連結具４７で連結した連結式の昇降機に代えたものである。第２実施例では、電気的構成において、前駆動源１２が無いのでこれへの供給電源等、及び、補正機能は不要であるから、構成が簡潔である。
【００４８】
図５に示す参考例は、第１実施例における前昇降機９及び前駆動源１２を除去し、前担架載せ部１５を支持腕４８によって後担架載せ部１６に固定する構成に代えたものである。
【００４９】
参考例では、前担架載せ部１５は、後担架載せ部１６に支持され一体的に昇降する。垂下状にある可動水受盤２１は、担架載せ部４が下降する時、間接的に、台車部１に当って水平方向へ回動する。
【００５０】
詳しくは、担架載せ部４が下降すると台車部１に当接する当接具６７が後駆動源１３の適宜位置に取着され、担架載せ部４が下降した時該当接具６７の作動変位を、可動水受盤２１へ伝達する水受盤連結具３６が、当接具６７と可動水受盤２１の間に連結される。
【００５１】
担架載せ部４が下降した時、当接具６７及び連結具３６を介して間接的に、可動水受盤２１が水平方向へ回動する。
【００５２】
図６に示す本発明の第３実施例は、第１実施例におけるの前昇降機９及び前駆動源１２を、前立設駆動源４９のみで構成し、前昇降機９を削除し、及び、後昇降機３及び後駆動源１３を、後立設駆動源５０のみで構成し、後昇降機１０を削除したものに代えている。
【００５３】
第３実施例では、前担架載せ部１５は前立設駆動源４９で昇降し、後担架載せ部１６は後立設駆動源５０で昇降する。前担架載せ部１５と台車部２にわたって、及び、後担架載せ部１６と台車部２にわたって、前・後担架載せ部１６の高さを検出する前・後担架位置検出器５１・５２が、それぞれ設けられる。
【００５４】
第３実施例では、第１実施例における前・後駆動源位置検出器３２・３３を担架位置検出器６３（＝前・後担架位置検出器５１・５２）に代え、前・後駆動源１１が作動時に、前・後担架位置検出器５１・５２の両出力信号を元に、前・後担架載せ部１５・１６の高さを均衡させる。図６中、７０は台車部２に立設されるガイド枠、７１は担架載せ部４側のフレ−ムに取着される枠ロ−ラ−、６６は可動水受盤２１の下端に設けられ、踏み台１４に当って転動するロ−ラ−、である。
【００５５】
図７に示す本発明の第４実施例は、第１実施例における前・後駆動源位置検出器３２・３３を、駆動源１１の傾斜角度を検出する駆動源角度検出器６４（＝前・後駆動源角度検出器５３・５４）に代えたものである。更に、第１実施例における前・後可動水受盤２２・２３を、台車部２に当って、該台車部２に押されて自動的に収縮する前・後収縮水受盤５５・５６に代えたものである。
【００５６】
第４実施例では、前・後駆動源１２・１３が作動時に、前・後駆動源位置検出器３１・３２の両出力信号を元に、前・後担架載せ部１５・１６の高さを均衡させる。第５実施例では、前・後担架載せ部１５・１６が下降すると垂下状にある前・後収縮水受盤５５・５６は、その収縮部５７が台車部２に押され蔓巻きバネ５８に抗して外筐部５９に退入する。
【００５７】
又、前・後収縮水受盤５５・５６は、前・後担架載せ部１５・１６が上昇すると退入状態にある収縮部５７が台車部２から離れ、蔓巻きバネ５８の伸展力に押されて退入状態から進出状態の常態に戻る。
【００５８】
又、図７には、駆動源位置検出器３２・３３の他の実施例として、駆動源位置検出器３２・３３に代えて、前・後担架載せ部１５・１６の角度を検出する担架載せ部角度検出器６０を付加例示している。
【００５９】
担架載せ部角度検出器６０は、前担架載せ部１５と後担架載せ部１６の間に掛け渡された渡し枠６１に取着される。渡し枠６１はその両端を前担架載せ部１５と後担架載せ部１６に軸６５・６８で止められる。
【００６０】
担架載せ部角度検出器６０は、前・後担架載せ部１５・１６の角度を検出し、前・後担架載せ部１５・１６が昇降時に、担架載せ部角度検出器６０の出力信号を元に駆動源１１を制御し、前・後担架載せ部１５・１６の角度の均衡を図るものである。通常は昇降時に前・後担架載せ部１５・１６が略水平を保つようにする。
【００６１】
図８に示す本発明の第５実施例は、第１実施例における可動水受盤２１をスライド可動水受盤６９に代えたものである。第５実施例では、担架載せ部４を下降させると垂下状のスライド可動水受盤６９はその下端が台車部１に当ると台車部１に押されて上方へ動く。
【００６２】
図示を省略するが、担架載せ部４が下降する事象をセンサ−で電気的に検出し、可動水受盤２１を検出信号に基づきモーターで水平方向へ回動させるという構成も可能である。
【００６３】
【発明の効果】
本発明は、上方に担架載せ部４が設けられる平面視略長方形状の搬送車１にはその長手方向の略中央部に介助者が出入りできる幅の前記搬送車１の一方側長辺から他方側長辺を横断する空間部５が設けられており、該空間部５の外方であって前記搬送車１の長手方向両側には前記担架載せ部４の一方側及び他方側をそれぞれ昇降させる昇降機３が配設され、介助者は前記搬送車１を浴槽に並置した後、前記空間部５内に入り込んで前記搬送車１と前記浴槽間における担架の移乗操作及び前記浴槽上へ移乗された前記担架上に臥す入浴者への介助作業が行えるものである。搬送車１を入浴に用いた場合には、搬送車１に載置される前記担架上の入浴者を、搬送車１と前記浴槽との間に移乗させる時、介助者は空間部５に入って該担架を操作できる。介助者は担架の移乗を、前屈みの苦しい姿勢になることなく、楽な姿勢で、容易に行なえ、好都合である。
【００６４】
又、身長の低い介助者は、搬送車１の側部から前記担架を前記浴槽へ移乗させることが甚だ困難であるといった従来装置の不都合を解消し、容易に担架を移乗させることができるようになり、好都合である。
【００６５】
又、入浴中の入浴者の介護又は看視が、搬送車１を除去移動させずにそのままの位置で容易にでき、搬送車１の操作に掛かる手数が減り、好都合である。
【００６６】
又、搬送車１に、載置した入浴者を昇降させる昇降機３が設けられているので、搬送車１を介助作業に最適の高さに調節でき、介助作業が容易になり、好都合である。
【００６７】
又、搬送時には、搬送車１を下降させ、入浴者を低位にして横揺れ等を少なくして、入浴者に不安感を与えず、安全に搬送でき、好都合である。
【００６８】
本発明は、前記搬送車１の長手方向両側に配設される各昇降機３に駆動源１１が設けられているので、昇降作動の応答が良好となり、担架載せ部４が安定に昇降し、介助作業の能率が向上が期待でき、好都合である。
【００６９】
本発明では、駆動源１１は、連動手段４０に連結されて連動し、連動手段４０は、駆動源１１の駆動量を補正する補正機能を有するので、該補正機能の作用により複数個の駆動源１１が適宜その駆動量が補正され、複数個の昇降機３が均衡して昇降し、異常傾斜等することが無く、好都合である。
【００７０】
本発明に係る補正機能は、前・後駆動源位置検出器３２・３３を有するので、駆動源１１のストロ−クを逐次検出しこの検出値を元に、複数個の昇降機３を均衡させて昇降でき、担架載せ部４を、異常傾斜させること無く安全に昇降させることができ、好都合である。
【００７１】
補正機能が前・後担架載せ部位置検出器５１・５２であるものでは、前・後担架載せ部１５・１６の位置を検出しこの検出値を元に、前・後担架載せ部１５・１６の高さ位置を均衡させながら昇降でき、好都合である。前・後担架載せ部位置検出器５１・５２を用いたものでは、駆動源１１から見て前・後担架載せ部１５・１６の検出部材が末端の部材であるので、安全性が高い。
【００７２】
