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安全機能付入浴装置に関する。
【０００２】
【従来の技術】
従来技術の実開平７−３７１７５号公報には、支柱、担架部、ベ−ス部、昇降式ストレッチャー、昇降式浴槽、浴槽本体、入浴装置、昇降式浴槽の底面又は昇降式ストレッチャーの上面に設けられるスイッチ、押圧部、制御回路等からなる入浴装置が開示されている。
【０００３】
【発明が解決しようとする課題】
前記従来装置は、上昇する浴槽が担架部に衝突し担架部を持ち上げると、担架部に繋がるベ−ス部も持ち上げられ、ベ−ス部に設けられたスイッチが浴槽に当たって作動させられ、浴槽が上昇を停止し、担架部の損傷を回避するというものである。前述の従来装置では、衝突を検出する部位が最初に衝突する衝突部位とは離れた異なる部位である。検出部位と衝突部位が同一部位でなく離れている故に衝突現象の検出の速さが劣り、及び正確さにも劣る。
【０００４】

【００４９】
又、図示を省略するが、前記昇降制御部６６は、浴槽部４が上昇中にある時、槽内取着位置検出器３９が担架取着位置被検出器４０に異状接近し作動すると、浴槽部４を一旦停止させ直ぐに下降させるという浴槽反応回路を含む。更に、搬送車２の昇降機３０は、担架２３が下降中にある時、担架取着位置被検出器４０が、槽内取着位置検出器３９に異状接近し作動すると、担架２３を一旦停止させ直ぐに上昇させる担架反応回路を含む。
【００５０】
又、浴槽部４が動いて担架２３に異状接近した時、該浴槽部４は停止し、担架２３が動き退き離間する構成としてもよい。或いは、浴槽部４が上昇して担架２３に異状接近した時、該浴槽部４は継続上昇し、浴槽部４と共に担架２３も上昇するものとしてもよい。即ち、担架２３は浴槽部４と一定距離を保って退避し、浴槽部４が担架２３へ衝突する事象を避ける。
【００５１】
又、図示を省略するが、安全機能８４の機能を解除する解除スイッチが、検出器２４に付随して設けられる。清掃時や保守点検時等に前記解除スイッチを投入すれば、搬送車２が浴槽１にセッティングされていなくても、浴槽１を任意に昇降させることができる。

【００５６】
第１実施例を使用して入浴する際は、搬送車２に取着された担架２３を水平状にて下降させ、入浴者を療養寝台等から担架２３に移乗させる。移乗後、背載置部３５を持ち上げ前傾リクライニング姿勢にする。然る後に、搬送車２を走行移動させ、湯を満たした浴槽１に接近し、担架２３を上昇させる。
【００５７】
次に、搬送車２の脚枠部１６を、浴槽１の切欠き部１７へ差し込み、該搬送車２を浴槽１の横側にセットする。搬送車２を浴槽１に対して適正位置にセットすると、脚枠部１６の搬送車位置被検出器２１がベ−ス部３の浴槽位置検出器２４に当接し該浴槽位置検出器２４が作動する。
【００５８】
浴槽位置検出器２４が作動すると、浴槽部４は昇降可能状態になり、該状態下で操作者は上昇スイッチ５５を押し、浴槽部４を上昇させ、入浴者を湯中に暫時浸け、入浴を行なう。
【００５９】
通常、搬送車２を上限位置に固定して入浴するため、浴槽部４が上限まで上昇しても、担架２３に浴槽部４底面が当たらないが、誤操作により担架２３が少し下がった位置で固定されていてその状態下で入浴作動をなした時、通常通りに浴槽部４が上昇中に該浴槽部４の槽内取着位置検出器３９が、臀部載置部３４の担架取着位置被検出器４０に異状接近し作動すると、浴槽部４の上昇移動が停止する。
【００６０】
退浴時は、操作者は下降スイッチ５７を押し浴槽部４を下降させ、入浴者及び担架２３を湯から出し、浴槽部４の上方に位置した担架２３を、搬送車２を浴槽１から引き離すと同時に浴槽部４から離す。次に、担架２３を下降させ、必要に応じて背載置部３５を水平にし、搬送車２を走行移動させ、入浴者を療養寝台へ移乗し、入浴を終わる。
【００６１】
上述のように浴槽部４を上昇させて担架２３に近づける操作とは異なる操作例として、浴槽部４を介助に好適な適宜高さに上昇させて停止させておき、次に、担架２３を適宜距離下降させて浴槽部４内に入れる。浴槽部４の上昇距離、及び担架２３の下降距離は使用時に適宜に選択する。又、非昇降式の浴槽部４に対して、昇降式の担架２３のみ下降させて該担架２３を浴槽部４へ入れ入浴する。
【００６２】
図６に示す参考例は、第１実施例における浴槽位置検出器２４を距離検出器６２に代え、及び、搬送車位置被検出器２１を支柱被検出器８３に代えたものである。
【００６３】
参考例に係る支柱被検出器８３は支柱２５に添って上下方向に取着される長尺形状の部材であり、距離検出器６２は、該支柱被検出器８３に所定間隔をもった接近状態で、浴槽部４と一体的に昇降している。
【００６４】
距離検出器６２は、支柱被検出器８３に近接しているとオン作動し、浴槽部４が昇降可能状態であり、この状態時に、上昇・下降スイッチ５５・５７を押せば、浴槽部４は随意に昇降させることができる。
【００６５】
距離検出器６２は、支柱被検出器８３から水平方向に所定距離以上に離間するとオフ作動し、浴槽部４は昇降不可能状態になる。例えば、浴槽部４が上昇中に、支柱被検出器８３から所定距離以上に離間し距離検出器６２がオフ作動すると、浴槽部４は停止する。同様に、浴槽部４が下降中に距離検出器６２がオフ作動すると、浴槽部４は停止する。
【００６６】
又、浴槽部４と担架２３との離合関係における安全機能８４の作用として、浴槽部４が、上昇中に万一の故障時に担架２３に異状接近すると、該浴槽部４の上昇は停止する。他の安全機能８４の作用例では、浴槽部４が上昇中に担架２３に異状接近すると浴槽部４と共に担架２３も上昇させ、浴槽部４と担架２３が一定距離を保って、両部材は衝突を回避する。
【００６７】
図７に示す第２実施例は、第１実施例の搬送車２が差し込み式であるのに対し、跨ぎ式搬送車９０であり、第１実施例における脚枠部１６、支柱２５及びアーム２６を、前・後縦フレーム８８・８９に代えたものである。第３実施例の跨ぎ式搬送車９０は、浴槽部４の前・後側壁１０・１４に検出器２４が設けられ、前後の脚フレーム８６に被検出器２１が設けられる。
【００６８】
跨ぎ式搬送車９０が浴槽部４の適正位置にセッティングされると、脚フレーム８６の被検出器２１が前・後側壁１０・１４の検出器２４を作動させ、浴槽部４が昇降可能となる。
【００６９】
尚、検出器２４は近接スイッチであり、被検出器２１は脚フレーム８６に設けられる磁石であるが、他の例では、脚フレーム８６の特定部位（＝押圧片）が前・後側壁１０・１４の押圧スイッチでなる検出器２４に直接当接し該検出器２４が作用するものとしてもよい。
