Description

【０００１】
【発明の属する技術分野】
本発明は、身体弱者用の用便装置に関する。
【０００２】
【従来の技術】
足腰の弱った老人、怪我人、病人、及び、身体障害者等の身体弱者が楽に着座・起立できるような介助機能を有する用便装置としては、例えば、便器本体の上方開口部の前端に、便座の前端を水平軸心廻りに揺動自在に枢着し、かつ、その便座の後半部を、ばねにて上方へ弾発的に押し上げるように構成したものが公知であった。また、身体弱者がトイレまで移動できないような場合は、寝室、ベッドサイドでいわゆるポータブルトイレを使用して排泄を行うのが一般的であった。
【０００３】
【発明が解決しようとする課題】
しかし、上述のような従来の用便装置では、着座する際や立ち上がる際に、便座が前傾状態となるため、前傾した便座に腰を下ろすと、身体全体が前下方へずり落ちてしまい、身体弱者が不安を感じるという問題があった。かつ、車椅子が必要な重度の身体障害者等を介護者が車椅子から便座に移動させるのが困難であった。また、トイレまで移動できないような身体弱者の場合、従来のポータブルトイレでは着座や立ち上がる際に足腰に苦痛を感じたり、立ち上がることができないことがあった。
【０００４】
そこで、本発明は、上述の問題を解決して、身体弱者の移動及び着座と起立を安全にかつ楽に行うことができる用便装置を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上述の目的を達成するために本発明に係る用便装置は、便座と、該便座を水平状の上昇位置と水平状の下降位置の間で昇降可能に支持する左右一対の平行四節リンクを有する支持枠と、該支持枠の一方の平行四節リンクを無段階揺動位置に停止可能に揺動駆動させる電動伸縮駆動体と、他方の平行四節リンクを上記便座が上昇する揺動方向へ弾発的に付勢する付勢手段と、を備えたものである。
【０００６】
また、支持枠が、左右一対の側枠部と、その一対の側枠部の縦杆部の上端部を橋絡する連結横杆と、を備え、平行四節リンクが、夫々、上記側枠部の縦杆部に一体に形成された後リンク部と、後端部がその後リンク部に枢結される上・下リンク杆と、該上・下リンク杆の前端部が枢結される前リンク部と、から構成され、該前リンク部と一体に揺動するように、アームレストが、該前リンク部に間接又は直接に着脱自在に取付けられている。
【０００７】
また、支持枠が、左右一対の側枠部と、その一対の側枠部の縦杆部の上端部を橋絡する連結横杆と、を備え、平行四節リンクが、夫々、上記側枠部の縦杆部に一体に形成された後リンク部と、後端部がその後リンク部に枢結される上・下リンク杆と、該上・下リンク杆の前端部が枢結される前リンク部と、から構成され、該前リンク部に、アームレストが、回倒・復起自在に又は上下動可能に、間接又は直接に取付けられている。
【０００８】
また、電動伸縮駆動体の下端部に長孔付き取付片を設け、その長孔付き取付片の長孔を貫通する水平支軸により、揺動可能として支持枠に該電動伸縮駆動体の下端部が枢着され、かつ、該電動伸縮駆動体を伸縮方向と略平行な斜め下方へ常時弾発的に付勢する弾発部材を、付設し、上記便座を押上げる方向への外力が作用したときに上記弾発部材に抗して上記電動伸縮駆動体が、斜め上方へ動いて逃げるように構成されている。また、便座が、平面的に見て環状とされている。
【０００９】
また、支持枠が、左右一対の側枠部と、その一対の側枠部の縦杆部の上端部を橋絡する連結横杆と、を備え、平行四節リンクが、夫々、上記側枠部の縦杆部に一体に形成された後リンク部と、後端部がその後リンク部に枢結される上・下リンク杆と、該上・下リンク杆の前端部が枢結される前リンク部と、から構成され、便座の上昇状態に於て、上記上・下リンク杆が水平又は前方下傾となるように構成されている。また、支持枠が、左右一対の側枠部と、その一対の側枠部の縦杆部の上端部を橋絡する連結横杆と、を備え、平行四節リンクが、夫々、上記側枠部の縦杆部に一体に形成された後リンク部と、後端部がその後リンク部に枢結される上・下リンク杆と、該上・下リンク杆の前端部が枢結される前リンク部と、から構成され、該前リンク部が下降状態に於て平行四節リンクの前下部に空間部が生じるように前傾姿勢とされている。また、便座に、便槽が着脱自在に取付けられている。
【００１０】
【発明の実施の形態】
以下、図示の実施の形態に基き本発明を詳説する。
【００１１】
図１と図２と図３と図４は本発明に係る用便装置の実施の一形態を示し、この装置は、足腰の弱った老人、怪我人、病人、及び、身体障害者等の身体弱者の用便時の着座及び立上がりを介助するためのものであり、洋式の便器本体Ａの上方に配設される便座１と、支持枠２は、便座１を水平状の上昇位置と水平状の下降位置の間で昇降可能に支持する左右一対の平行四節リンク８，８を有する支持枠２と、その支持枠２の左右一対の平行四節リンク８，８の内の一方の平行四節リンク８を無段階揺動位置に停止可能に揺動駆動させる電動伸縮駆動体３と、他方の平行四節リンク８を便座１が前方下傾となる揺動方向へ弾発的に付勢する付勢手段35と、を備える。付勢手段35は、図２ではガススプリングの例を示す。なお、この付勢手段35はガススプリングに限定するものではなく、コイルバネ、板バネ、空気バネ、トーションバー等、他方の平行四節リンク８を便座１が前方下傾となる揺動方向へ弾発的に付勢可能なものであればよい。
【００１２】
支持枠２は、床面上に固定又は載置される水平杆部４ａとその後端部に連設される縦杆部４ｂと縦杆部４ｂに一体に形成される後リンク部42とから成る左右一対の側枠部４，４と、その一対の側枠部４，４の縦杆部４ｂの上端部を橋絡する連結横杆５と、を備える。
【００１３】
また、平行四節リンク８は、側枠部４の縦杆部４ｂに一体に形成された後リンク部42と、その後リンク部42に後端部が枢結される上・下リンク杆９，10と、上・下リンク杆９，10の前端部が枢結される前リンク部11と、から構成され、上・下リンク杆９，10が平行とされると共に、その上・下リンク杆９，10の後端の２つの枢結軸Ｓ₁ , Ｓ₂ を通る直線Ｌと、上・下リンク杆９，10の前端の２つの枢結軸Ｓ₃ , Ｓ₄ を通る直線Ｍが、平行とされている。
【００１４】
さらに、図４に示すように、便座１の上昇状態に於て、上・下リンク杆９，10が前方下傾となるように構成する。また、支持枠２の側枠部４の縦杆部４ｂをやや前方に傾斜させる。これにより、左右の縦杆部４ｂ，４ｂの上端を相互に連結する連結横杆５がやや前方へ移動し、便器本体Ａの後方の水タンクＴに当たらない。かつ、便座１が前上方へ上昇するので便座の後端部が支持枠２の連結横杆５に干渉することが無い。また、洗浄水を人の局部に向けて噴射するノズルを有する局部洗浄装置を便座１の後部に取付けても、その局部洗浄装置が連結横杆５に干渉しない。また、縦杆部４ｂが枢結軸Ｓ₁ , Ｓ₂ を通る直線Ｌと同方向に傾斜するので、設計上合理的である。なお、便座１の上昇状態に於て、上・下リンク杆９，10が水平となるように構成してもよい。
【００１５】
また、図１と図２と図３に示すように、前リンク部11は、下降状態に於て、平行四節リンク８の前下部に空間部Ｒが生じるように前傾姿勢とされている。また、左右一対の平行四節リンク８，８の上リンク杆９，９は、横連結部材６にて相互に連結される。横連結部材６は、上リンク杆９，９に上方突出状に固設された支持片６ａ，６ａと、その支持片６ａ，６ａの間に固定状に設けられる横連結杆６ｂと、から成る。横連結杆６ｂは、下降状態に於て、便座１の後端部の下面を受ける。
【００１６】
しかして、アームレスト７が、前リンク部11と一体に揺動するように、前リンク部11に間接に着脱自在に取付けられている。具体的には、図３と図４と図５に示すように、平行四節リンク８，８の前リンク部11，11に、取付支持部12，12が上方延伸状に設けられ、その取付支持部12，12の上端部に平面的に見て環状の便座１の前部の左右両側面が固着される。かつ、その取付支持部12，12の上端部に上方及び側方へ開口する凹部44が設けられると共にボルト部材45, 45が側方突出状に固着された連結部43を設ける。
【００１７】
また、アームレスト７は、水平部７ａと、その水平部７ａの前方に連設される手掛け部７ｂを、有している。そして、アームレスト７の途中部下面に取付用縦部材46の上端部が固着される。その取付用縦部材46は、取付支持部12の凹部44に嵌脱自在に嵌入する嵌入凸部47を下端部に有する。かつ、その嵌入凸部47の側外面に、取付支持部12のボルト部材45, 45が挿通される小貫孔48, 48を有する取付片49が固着される。しかして、取付支持部12の凹部44に嵌入凸部47を嵌めると共に取付片49の小貫孔48, 48にボルト部材45, 45のねじ軸部を挿通させてそのねじ軸部に先端側からナット部材50, 50を螺嵌することにより、アームレスト７を前リンク部11に間接的に取付ける。また、ナット部材50, 50を螺退させて取外せば、アームレスト７を取外すことができる。一方のアームレスト７の先端には、電動伸縮駆動体３の伸縮操作をするためのスイッチ30が取付けられる。なお、左右両方のアームレスト７，７ともに、図５にて説明した構造にて着脱自在とされる。また、連結部43にねじ孔を設け、アームレスト７側の取付片49の小貫孔48, 48に、別体としてのボルト部材を挿通させて連結部43のねじ孔に螺入させることにより、アームレスト７を取付けるように構成してもよい。
【００１８】
また、図１と図３と図４に示すように、電動伸縮駆動体３は、上端部が支持枠２の一方の平行四節リンク８に設けられた取付支持部12に枢着される上部材15と、下端部が支持枠２の一方の側枠部４に枢着される下部材16と、を備えている。
【００１９】
具体的には、図６の断面図に示すように、上部材15は、円筒状の内筒体15ａの下端にナット部材15ｂを固着して成る（なお、図６では紙面に向かって左側を上、右側を下として描いてある）。つまり、上部材15は、下端に雌ねじ部17を有する。また、内筒体15ａの上端部には、枢結用の貫孔18ａを有するボス部18が設けられる。
【００２０】
また、下部材16は、枢結用の長孔付き取付片14が下端に突設されたケーシング22と、そのケーシング22に上方突出状に設けられると共に上部材15がスライド自在に挿入される外筒体20と、上部材15の下端の雌ねじ部17に螺進退自在に螺合するスクリューシャフト24と、ケーシング22に取付けられる電動モータ23と、その電動モータ23とスクリューシャフト24を連動連結する減速機構25と、を有する。
【００２１】
減速機構25は、例えば、相互に噛合する大径と小径のヘリカル歯車からなり、大径のヘリカル歯車をスクリューシャフト24の下端に固着し、小径のヘリカル歯車を電動モータ23の出力軸に固着する。
【００２２】
しかして、スクリューシャフト24が矢印Ｂ方向へ回転するように電動モータ23を回転駆動させると、ナット部材15ｂが上昇して内筒体15ａが外筒体20から上方へ出て行くため、電動伸縮駆動体３の長さが増加する。また、電動伸縮駆動体３の伸長状態に於て、スクリューシャフト24が矢印Ｃ方向へ回転するように電動モータ23を回転駆動させると、ナット部材15ｂが下降して内筒体15ａが外筒体20に挿入されて行くため、電動伸縮駆動体３の長さが減少する。
【００２３】
なお、図１〜図４に於て、スイッチ30を上方へ揺動させれば、電動伸縮駆動体３が伸長し、下方へ揺動させれば電動伸縮駆動体３が短縮し、スイッチ30から手を離せば電動伸縮駆動体３が停止するように、構成する。
【００２４】
（図６にもどって）外筒体20には、上・下リミットスイッチ34ａ，34ｂが付設される。そのリミットスイッチ34ａ，34ｂは、上部材15の内筒体15ａの下部に設けられた突部を検知するように構成され、その検知信号により、電動モータ23が停止する。即ち、電動伸縮駆動体３の長さが最大になった時及び最小になった時に、自動的に停止する。なお、図４は、電動伸縮駆動体３を最短とした状態を示す。
【００２５】
また、図７と図８と図９に示すように、電動伸縮駆動体３の下端部───下部材16の下端部───に長孔付き取付片14を設け、その長孔付き取付片14の長孔14ａを貫通する水平支軸36により、揺動可能として支持枠２に該電動伸縮駆動体３の下端部を枢着し、かつ、電動伸縮駆動体３を伸縮方向と略平行な斜め下方へ常時弾発的に付勢する弾発部材37を、付設する。水平支軸36は、支持枠２の側枠部４の水平杆部４ａに上方突出状に固着された支持片38の上部に固着される。また、長孔付き取付片14と支持枠２の側枠部４には、それぞれ、ばね係止部40ａ，40ｂが設けられ、そのばね係止部40ａ，40ｂに弾発部材37としての引張りばねの両端部が係止される。
【００２６】
そして、便座１を下降させる際に便座１と便器本体Ａとの間に手等が挟まって、便座１を押上げる方向への外力が作用したときに、弾発部材37に抗して電動伸縮駆動体３が、矢印Ｅにて示す如く斜め上方へ動いて逃げるように構成する。なお、電動伸縮駆動体３が斜め上方へ動いて逃げることができるストローク幅Ｗは、便座１と便器本体Ａとの間に手等が挟まっても怪我をしないような値に設定される（図８と図９参照）。
【００２７】
しかして、この装置に着座するには、図４に示すように、便座１を上昇させて、便座１に腰掛ける。このとき、便座１は下降状態に比してやや前方へ移動しているので、便器本体Ａが邪魔となることがない。なお、このときの便座１の前端部の高さは、起立した人の臀部よりも僅かに低い高さである。
【００２８】
これにより、僅かに腰を低くするのみで臀部が便座１に当接して、着座する人を中腰状態に支持することができる。また、この上昇位置に於て、便座１が水平状態に維持されるので、身体が便座１からずり落ちる虞れが無く身体弱者が不安を感ずることが無くかつ安全である。その後、アームレスト７の先端のスイッチ30を下方へ揺動させれば、電動伸縮駆動体３が一定速度で短縮して、便座１がゆっくりと後下方へ下降する。
【００２９】
その後、便座１が図３に示すように便器本体Ａの真上位置にまで下降して、電動伸縮駆動体３のリミットスイッチが作動し自動的に停止する。こうして、便座１が水平状の下降位置に保持される。このとき、平行四節リンク８，８の前下部に空間部Ｒが生じるので、身体弱者の足の動きの邪魔とならない。
【００３０】
次に、用便を済ませた後、スイッチ30を上方へ揺動させれば、電動伸縮駆動体３が一定速度で伸長して、便座１がゆっくりと前上方へ上昇する。その後、前述の如く、便座１が水平状態のまま上昇位置に到達すると、電動伸縮駆動体３が自動的に停止する。
【００３１】
これにより、便座１が十分高い位置で停止するので、起立状態に近い位置にまで臀部が押し上げられる。かつ、便座１が水平状に保持されるので、臀部が便座１からずり落ちることが無く安全である。従って、身体弱者にでも自力で楽に、かつ、安全に立ち上がることができる。
【００３２】
また、便座１の下降時又は上昇時に於て、スイッチ30から手を離せば、そのときの位置に便座１を停止できる。これにより、途中で一服したい場合や、座り直したい場合等に便利であり、使用者が立ち上がり易い任意の位置で便座１を停止できるという利点もある。かつ、安全面でより優れる。さらに、便座１の下降速度及び上昇速度は、着座する人の体重の大小に関係なくほぼ一定であり、便座１はゆっくりと下降又は上昇するため、安全性が一層高い。
【００３３】
また、平行四節リンク８により、便座１全体が前上方へ押し出されるので、身体弱者の臀部を前上方へ押し出すことができ、一層立ち上がり易い。さらに、支持枠２の前端部に支柱等の邪魔なものが無いので、狭いトイレに設置しても、身体弱者の出入りの邪魔とならないという利点がある。
【００３４】
さらに、図７にて説明したように、掃除中等に於て、誤って電動伸縮駆動体３が作動して便座１と便器本体Ａとの間に手等が挟まっても、弾発部材37に抗して電動伸縮駆動体３が、矢印Ｅにて示す如く斜め上方へ動いて逃げる。即ち、通常の（手等を挟んでいない）下降状態では、図８に示すように、電動伸縮駆動体３が下方に降りて長孔14ａの上端部に水平支軸36が位置しているが、上記の如く手等を挟むと、図９に示すように、便座が下降せずに弾発部材37の弾発力に抗して電動伸縮駆動体３が斜め上方へ逃げる。これにより、便座１と便器本体Ａとの間で手等が潰れることが無く安全性に一層優れる。
【００３５】
また、図５にて説明したように、アームレスト７を取外して使用するのも好ましい。そのようにすれば、自力で用便ができないような重度の身体障害者を介護者が車椅子から便座１に移動させることや便座１から車椅子に移動させることが容易となる。
【００３６】
なお、この用便装置は、ばねの弾発力により便座を押し上げるように構成した従来の用便装置に比して、水平状態を保持するためのロック機構が不要である点、及び、押上力を調整するためにばね部材の取付位置を変更するための機構が不要である点に於て、優れている。かつ、中間の任意の高さ位置で便座１を停止できるという利点もある。
【００３７】
また、電動伸縮駆動体３にて一方の平行四節リンク８を上方へ揺動させ、かつ、付勢手段35にて他方の平行四節リンク８を上昇方向へ弾発付勢するので、左右の平行四節リンク８，８をこぜを生ずることなくバランスよく昇降させることができると共に全体の構成部材を簡素化できる。さらに、横連結部材６と環状の便座１により、その横連結部材６と便座１と左右の平行四節リンク８，８とからなる構造の剛性を大きくすることができ、上昇・下降時及び停止時に、便座１がぐらついたり左右に傾いたりするのを防止でき、一層安全性が高い。
【００３８】
また、平行四節リンク８，８の前リンク部11，11に、便座１とアームレスト７，７を直接に着脱自在に取付けるも自由である。その場合、前リンク部11の上端部に凹部44を設けると共にボルト部材45, 45を固着し、かつ、アームレスト７に上下方向に長寸の取付支持部12を固着すればよい。
【００３９】
次に、図10と図11は他の実施の形態を示し、前リンク部11に、アームレスト７が、間接に、回倒・復起可能に取付けられている。具体的には、図10に示すように、取付支持部12の上端部と、アームレスト７の取付用縦部材46の下端部を、ヒンジ機構60とロック・解除機構61を介して、前後方向の水平軸心廻りに回動可能に、かつ、アームレスト７を回倒可能な解除状態と、復起状態に保持可能なロック状態とに、切換自在に、連結する。そして、アームレスト７を便座１よりも低い位置まで、側外方へ回倒可能とする。
【００４０】
ロック・解除機構61は、図11に示すように、取付支持部12に固着される取付片62と、その取付片62に前後方向スライド自在に取付けられるスライド部材63と、取付用縦部材46に固着されると共に、スライド部材63の半球状の先端部が挿入・離脱自在に挿入される孔部64を有する係止片65と、スライド部材63を先端側へ弾発付勢する弾発部材66と、を備える。
【００４１】
しかして、スライド部材63を、矢印Ｇにて示す如く基端方向へ引けば、先端部が孔部64から抜けて、解除状態となり、アームレスト７を、図10に矢印Ｈにて示す如く、側外方へ倒すことができる。
【００４２】
また、アームレスト７を、倒れた状態から、矢印Ｉにて示すように起こすと、ロック・解除機構61のスライド部材63の先端が自動的に孔部64に入り、ロック状態となる（図11参照）。なお、前リンク部11に、アームレスト７を直接に回倒・復起可能に取付けてもよい。その場合、前リンク部11の上部と取付用縦部材46の下部の間にヒンジ機構60とロック・解除機構61を設ければよい。
【００４３】
次に、図12と図13は、別の実施の形態を示し、前リンク部11に、アームレスト７が、間接に、上下動可能に取付けられている。即ち、図12に示すように、取付支持部12の上部に、上下方向の角孔部68を成す取付金具67が固着され、その取付金具67にて形成された角孔部68に、アームレスト７の取付用縦部材46が、上方から挿入される。そして、アームレスト７を、便座１の上面と略同等の位置に下降可能とする。
【００４４】
しかして、図12と図13に示すように、取付金具67には、ロック・解除用のスライド部材69が側方へスライド自在に取付けられ、取付用縦部材46には、スライド部材69の半球状先端部が挿入・離脱自在に挿入される複数の孔部70…が、上下に所定ピッチ毎に設けられる。また、取付金具67とスライド部材69の先端の頭部との間に、スライド部材69を先端へ弾発付勢する弾発部材71が介装される。
【００４５】
上述の構成により、スライド部材69を側外方へ引けば、その先端部が孔部70から抜けて、アームレスト７を上下動させることができる。また、スライド部材69から手を離して、アームレスト７をゆっくり上昇又は下降させれば、孔部70にスライド部材69の先端が自動的に入って、ロック状態となり、アームレスト７の高さをそのまま維持できる。従って、アームレスト７の高さ調整ができる。かつ、アームレスト７を最下位置にまで下降させれば、重度の身体障害者の乗り降りの際に邪魔とならない。また、取付用縦部材46を角孔部68から上方へ引抜いて、アームレスト７を取外すこともできる。
【００４６】
なお、前リンク部11に、アームレスト７を、直接に上下動可能に、取付けてもよい。その場合、前リンク部11の上部側外面に取付金具67を固着して角孔部68を形成し、その角孔部68に取付用縦部材46を挿入すればよい。
【００４７】
また、図14と図15は、便座１に、便槽81を着脱自在に取付けたものである。即ち、図14の用便装置は、便座１の下面の左右両側に、正面視Ｌ字型のレール状の引掛け部80, 80が相互に対向状に固着されている。便槽81は上端縁に外鍔部81ａを有する。そして、便槽81の外鍔部81ａを引掛け部80, 80に係止する。これにより、この用便装置を使用した後は、便槽81を前方へ引き抜いて便座１から取り外して排泄物を容易に捨てることができる。
【００４８】
また、図15の用便装置は、便座１に便槽81を着脱自在に取付けるための引掛け部材82, 82が、便座１に着脱自在に取付けられている。即ち、引掛け部材82, 82は、便座１に係脱自在に係止する係止部82ａと、その係止部82ａの下端部に形成される引掛け本体部82ｂと、から成る。このように構成したことにより、引掛け部材82, 82や便座１の裏に汚物が付着した場合に、便座１から引掛け部材82, 82を取り外せば、簡単に清掃ができる。従って、清掃性に優れて衛生的である。
【００４９】
なお、本発明は上述の形態以外の形態とするも可能であり、例えば、本装置に、洗浄水を人の局部に向けて噴射するノズルを有する局部洗浄装置を付設するも自由である。その場合、便座１の後部下面側又は横連結部材６にノズルを（洗浄水が略上方へ噴射されるように）取付ければよい。また、付勢手段35としては、ガススプリング以外にも、例えば、コイルばねや板ばねを使用してもよい場合がある。
【００５０】
【発明の効果】
本発明は上述の構成により、次のような著大な効果を奏する。
【００５１】
請求項１記載の用便装置によれば、便座１を水平状に維持したままで昇降できるので、便座１の上昇状態に於て、着座する際に身体が便座１からずり落ちることが無く、不安を感じることが無い。かつ、身体弱者が用便の前後で楽に着座及び起立することができる。特に、電動伸縮駆動体３が一方にのみ設けられているにかかわらず、付勢手段35を他方に配することによって、安定して支持枠２等が昇降して、便座１の上昇・下降時及び停止時に、便座１がぐらついたり左右に傾いたりするのを防止できる。また、着座した状態で便座１が不意に浮き上がる虞が無く、安全性が高い。その上、便座１を上昇又は下降の途中の任意の位置に停止させることも可能であり、途中で一服したい場合や立ち上がり易い上昇位置で止めたい場合に便利である。さらに、着座する際と起立する際に、便座１がゆっくりと下降又は上昇するので、安全が一層高くなり、身体弱者が安心して使用できる。また、全体の構造を簡素化できる。
【００５２】
請求項２記載の用便装置によれば、請求項１記載のものと同様の効果を奏すると共に、アームレスト７，７を取付けた状態に於て、便座１とアームレスト７，７が一体状に下降及び上昇するので、着座及び立ち上がりを一層楽にかつ安全に行い得る。かつ、立ち上がる際に力を入れ易い。また、アームレスト７，７を取外せば、自力で用便ができないような重度の身体障害者を介護者が車椅子から便座１に移動させることや便座１から車椅子に移動させることが容易となる。
【００５３】
請求項３記載の用便装置によれば、請求項１記載のものと同様の効果を奏すると共に、便座１とアームレスト７，７が一体状に下降及び上昇するので、着座及び立ち上がりを一層楽にかつ安全に行い得る。そして、アームレスト７が、回倒・復起自在なものでは、アームレスト７を倒せば、自力で用便ができないような重度の身体障害者を介護者が車椅子から便座１に移動させることや便座１から車椅子に移動させることが容易となる。また、アームレスト７が、上下動可能なものでは、アームレスト７の高さ調整ができ、使用者（身体弱者）の体に合った最も楽な姿勢をとることができる。
【００５４】
請求項４記載の用便装置によれば、請求項１、２又は３記載のものと同様の効果を奏すると共に、掃除中等に於て、誤ってスイッチに触れて電動伸縮駆動体３が作動して便座１と便器本体Ａとの間に手や腕等が挟まっても、弾発部材37に抗して電動伸縮駆動体３が、斜め上方へ動いて逃げるので、便座１がそれよりも下降することが無く、安全性に一層優れる。
【００５５】

[0010]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail below based on the illustrated embodiment.
[0011]
1, 2, 3, and 4 show an embodiment of a toilet device according to the present invention, which is used for an elderly person, an injured person, a sick person, and a physically handicapped person with weak legs. The toilet seat 1 disposed above the western toilet body A and the support frame 2 are for assisting the seating and rising of the vulnerable person in the stool. The support frame 2 having a pair of left and right parallel four-bar links 8 and 8 supported so as to be movable up and down between the lowered positions, and one of the pair of left and right parallel four-bar links 8 and 8 of the support frame 2. The electric telescopic drive body 3 that swingably drives the node link 8 to the stepless swing position and the other parallel four-bar link 8 are elastically biased in the swinging direction in which the toilet seat 1 tilts forward and downward. And urging means 35. The biasing means 35 shows an example of a gas spring in FIG. The biasing means 35 is not limited to a gas spring, and the other parallel four-bar link 8 such as a coil spring, a leaf spring, an air spring, or a torsion bar is elastically moved in a swinging direction in which the toilet seat 1 tilts forward and downward. It may be anything that can be energized on its own.
[0012]
The support frame 2 includes a horizontal hook 4a fixed or placed on the floor, a vertical hook 4b connected to the rear end thereof, and a rear link 42 formed integrally with the vertical hook 4b. A pair of left and right side frame parts 4 and 4 and a connecting horizontal gutter 5 that bridges the upper end of the vertical gutter part 4b of the pair of side frame parts 4 and 4 are provided.
[0013]
The parallel four-bar link 8 includes a rear link portion 42 formed integrally with the vertical flange portion 4b of the side frame portion 4, and upper and lower link rods 9 whose rear end portions are pivotally connected to the rear link portion 42, 10 and a front link portion 11 to which the front end portions of the upper and lower link rods 9 and 10 are pivoted, and the upper and lower link rods 9 and 10 are made parallel, and the upper and lower link rods Two pivot axes S at the rear end of 9, 10 ₁ , S ₂ A straight line L passing through and two pivot axes S at the front ends of the upper and lower link rods 9 and 10 _Three , S _Four A straight line M passing through is parallel.
[0014]
Further, as shown in FIG. 4, the upper and lower link rods 9 and 10 are configured to be inclined forward and downward when the toilet seat 1 is raised. Further, the vertical flange 4b of the side frame 4 of the support frame 2 is slightly inclined forward. As a result, the connecting horizontal gutter 5 that connects the upper ends of the left and right vertical gutter portions 4b, 4b moves slightly forward and does not hit the water tank T behind the toilet body A. In addition, since the toilet seat 1 rises forward and upward, the rear end portion of the toilet seat does not interfere with the connecting reed 5 of the support frame 2. Moreover, even if a local cleaning device having a nozzle for injecting cleaning water toward a local part of a person is attached to the rear portion of the toilet seat 1, the local cleaning device does not interfere with the connecting reed 5. Also, the vertical shaft 4b is connected to the pivot axis S. ₁ , S ₂ It is rational in design because it is inclined in the same direction as the straight line L passing through. Note that the upper and lower link rods 9 and 10 may be configured to be horizontal when the toilet seat 1 is raised.
[0015]
As shown in FIGS. 1, 2, and 3, the front link portion 11 is inclined forward so that a space portion R is generated in the lower front portion of the parallel four-bar link 8 in the lowered state. . Further, the upper link rods 9, 9 of the pair of left and right parallel four-bar links 8, 8 are connected to each other by the horizontal connecting member 6. The horizontal connecting member 6 includes support pieces 6a and 6a fixed to the upper link rods 9 and 9 so as to protrude upward, and a horizontal connection rod 6b fixedly provided between the support pieces 6a and 6a. . The horizontal connecting rod 6b receives the lower surface of the rear end portion of the toilet seat 1 in the lowered state.
[0016]
Thus, the armrest 7 is detachably attached to the front link portion 11 so as to swing integrally with the front link portion 11. Specifically, as shown in FIGS. 3, 4, and 5, mounting support portions 12, 12 are provided on the front link portions 11, 11 of the parallel four-bar links 8, 8 so as to extend upward. The left and right side surfaces of the front portion of the annular toilet seat 1 are fixed to the upper ends of the support portions 12 and 12 when viewed in plan. Further, a concave portion 44 that opens upward and laterally is provided at the upper end portion of the mounting support portions 12 and 12, and a connecting portion 43 to which the bolt members 45 and 45 are fixed in a laterally projecting manner is provided.
[0017]
Moreover, the armrest 7 has the horizontal part 7a and the handle part 7b provided in a row in front of the horizontal part 7a. The upper end portion of the mounting vertical member 46 is fixed to the lower surface of the middle portion of the armrest 7. The vertical member for attachment 46 has an insertion convex portion 47 at the lower end portion, which is detachably inserted into the concave portion 44 of the attachment support portion 12. In addition, a mounting piece 49 having small through holes 48 and 48 through which the bolt members 45 and 45 of the mounting support portion 12 are inserted is fixed to the outer surface on the side of the fitting convex portion 47. Then, the fitting convex portion 47 is fitted into the concave portion 44 of the mounting support portion 12, and the screw shaft portion of the bolt members 45, 45 is inserted into the small through holes 48, 48 of the mounting piece 49, and the nut is inserted into the screw shaft portion from the tip side. The armrest 7 is indirectly attached to the front link portion 11 by screwing the members 50 and 50 together. Further, the armrest 7 can be removed by removing the nut members 50, 50 by screwing them off. A switch 30 for performing an expansion / contraction operation of the electric expansion / contraction driving body 3 is attached to the tip of one armrest 7. Both the left and right armrests 7 are detachable with the structure described in FIG. In addition, a screw hole is provided in the connecting portion 43, and a bolt member as a separate body is inserted into the small through holes 48, 48 of the attachment piece 49 on the armrest 7 side so as to be screwed into the screw hole of the connecting portion 43. You may comprise so that 7 may be attached.
[0018]
As shown in FIGS. 1, 3, and 4, the electric telescopic drive body 3 is pivotally attached to an attachment support portion 12 provided at an upper end portion of one parallel four-bar link 8 of the support frame 2. A member 15 and a lower member 16 whose lower end is pivotally attached to one side frame 4 of the support frame 2 are provided.
[0019]
Specifically, as shown in the cross-sectional view of FIG. 6, the upper member 15 is formed by fixing a nut member 15b to the lower end of a cylindrical inner cylinder 15a (in FIG. It is drawn with the top and right side down.) That is, the upper member 15 has a female thread portion 17 at the lower end. Further, a boss portion 18 having a pivotal through hole 18a is provided at the upper end portion of the inner cylinder 15a.
[0020]
Further, the lower member 16 includes a casing 22 having an elongated attachment hole 14 for pivoting projecting at the lower end, an outer projecting shape provided on the casing 22 and an upper member 15 being slidably inserted. A cylindrical body 20, a screw shaft 24 that is screwed into the female thread portion 17 at the lower end of the upper member 15 so as to be able to advance and retreat, an electric motor 23 attached to the casing 22, and a reduction gear that interlocks and connects the electric motor 23 and the screw shaft 24 And a mechanism 25.
[0021]
The reduction mechanism 25 includes, for example, a large-diameter and a small-diameter helical gear that mesh with each other, and the large-diameter helical gear is fixed to the lower end of the screw shaft 24, and the small-diameter helical gear is fixed to the output shaft of the electric motor 23. .
[0022]
Thus, when the electric motor 23 is rotationally driven so that the screw shaft 24 rotates in the direction of arrow B, the nut member 15b rises and the inner cylinder 15a goes out from the outer cylinder 20, so that the electric expansion and contraction is performed. The length of the driving body 3 increases. Further, when the electric motor 23 is driven to rotate so that the screw shaft 24 rotates in the direction of arrow C in the extended state of the electric telescopic driving body 3, the nut member 15b is lowered and the inner cylinder 15a is changed to the outer cylinder. Since it is inserted into 20, the length of the electric telescopic drive body 3 is reduced.
[0023]
1 to 4, if the switch 30 is swung upward, the electric telescopic drive body 3 is extended, and if it is swung downward, the electric telescopic drive body 3 is shortened. The electric telescopic drive body 3 is configured to stop when the hand is released.
[0024]
(Returning to FIG. 6) The upper and lower limit switches 34a and 34b are attached to the outer cylinder 20. The limit switches 34a and 34b are configured to detect a protrusion provided on the lower portion of the inner cylinder 15a of the upper member 15, and the electric motor 23 is stopped by the detection signal. That is, it automatically stops when the length of the electric telescopic drive body 3 is maximized and minimized. FIG. 4 shows a state where the electric telescopic drive body 3 is the shortest.
[0025]
Further, as shown in FIGS. 7, 8 and 9, a mounting hole 14 with a long hole is provided at the lower end of the electric telescopic drive body 3—the lower end of the lower member 16—and the mounting with the long hole is performed. A horizontal support shaft 36 penetrating the long hole 14a of the piece 14 is pivotally attached to the support frame 2 so as to be swingable, and the electric telescopic drive body 3 is substantially parallel to the telescopic direction. A resilient member 37 that is always resiliently biased downward is provided. The horizontal support shaft 36 is fixed to an upper portion of a support piece 38 fixed to the horizontal flange portion 4a of the side frame portion 4 of the support frame 2 so as to protrude upward. Further, the attachment piece 14 with the long hole and the side frame portion 4 of the support frame 2 are provided with spring locking portions 40a and 40b, respectively, and the spring locking portions 40a and 40b are tension springs as the elastic members 37. Both ends of the are locked.
[0026]
When the toilet seat 1 is lowered, a hand or the like is sandwiched between the toilet seat 1 and the toilet body A, and when an external force in the direction of pushing up the toilet seat 1 acts, the elastic member 37 is electrically stretched against the elastic member 37. As shown by the arrow E, the driving body 3 is configured to move obliquely upward and escape. It should be noted that the stroke width W that allows the electric telescopic drive 3 to move obliquely upward and escape is set to a value that does not cause injury even if a hand or the like is caught between the toilet seat 1 and the toilet body A (FIG. 8 and FIG. 9).
[0027]
To sit on this device, the toilet seat 1 is raised and seated on the toilet seat 1 as shown in FIG. At this time, since the toilet seat 1 has moved slightly forward compared to the lowered state, the toilet body A does not get in the way. In addition, the height of the front-end part of the toilet seat 1 at this time is slightly lower than the heel of the person who stood up.
[0028]
As a result, it is possible to support the seated person in the middle waist state with the buttocks abutting against the toilet seat 1 only by lowering the waist slightly. In addition, since the toilet seat 1 is maintained in the horizontal state at this raised position, there is no possibility that the body slides down from the toilet seat 1, and it is safe for the weak to feel no anxiety. Thereafter, if the switch 30 at the tip of the armrest 7 is swung downward, the electric telescopic drive body 3 is shortened at a constant speed, and the toilet seat 1 is slowly lowered rearward and downward.
[0029]
Thereafter, the toilet seat 1 is lowered to a position directly above the toilet body A as shown in FIG. 3, and the limit switch of the electric telescopic driving body 3 is activated to automatically stop. Thus, the toilet seat 1 is held in the horizontal lowered position. At this time, since the space R is formed in the front lower part of the parallel four-bar links 8, 8, it does not interfere with the movement of the weakly-worked person.
[0030]
Next, after the stool is finished, if the switch 30 is swung upward, the electric telescopic drive body 3 extends at a constant speed, and the toilet seat 1 slowly rises forward and upward. Thereafter, as described above, when the toilet seat 1 reaches the raised position in the horizontal state, the electric telescopic driving body 3 automatically stops.
[0031]
Thereby, since the toilet seat 1 stops at a sufficiently high position, the buttocks are pushed up to a position close to the standing state. And since the toilet seat 1 is hold | maintained horizontally, a buttocks does not slide down from the toilet seat 1, and it is safe. Therefore, even a weak person can stand up easily and safely by himself.
[0032]
Further, when the toilet seat 1 is lowered or raised, if the hand is released from the switch 30, the toilet seat 1 can be stopped at the position at that time. This is convenient for taking a dose on the way or re-sitting, and has the advantage that the toilet seat 1 can be stopped at any position where the user can easily stand up. And it is better in terms of safety. Furthermore, the descending speed and the ascending speed of the toilet seat 1 are substantially constant regardless of the weight of the person who is seated, and the toilet seat 1 slowly descends or rises, so that safety is further enhanced.
[0033]
Further, since the entire toilet seat 1 is pushed forward and upward by the parallel four-bar link 8, the buttocks of the weak body can be pushed forward and upward, and it is easier to stand up. Furthermore, since there is no obstruction such as a support post at the front end of the support frame 2, there is an advantage that even if it is installed in a narrow toilet, it does not obstruct the entry and exit of the physically weak.
[0034]
Further, as described with reference to FIG. 7, even during cleaning, even if the electric telescopic drive body 3 is mistakenly operated and a hand or the like is sandwiched between the toilet seat 1 and the toilet body A, the elastic member 37 On the contrary, the electric telescopic driving body 3 moves obliquely upward as shown by an arrow E and escapes. That is, in a normal lowered state (without a hand or the like), as shown in FIG. 8, the electric telescopic drive body 3 descends downward and the horizontal support shaft 36 is located at the upper end of the long hole 14a. When the hand or the like is sandwiched as described above, the electric telescopic drive body 3 escapes obliquely upward against the resilient force of the resilient member 37 without lowering the toilet seat as shown in FIG. Thereby, a hand etc. are not crushed between the toilet seat 1 and the toilet bowl main body A, and it is further excellent in safety | security.
[0035]
Further, as described with reference to FIG. 5, it is also preferable to remove the armrest 7 for use. If it does in that way, it will become easy for a caregiver to move the seriously handicapped person who cannot use the stool by himself / herself from the wheelchair to the toilet seat 1 or from the toilet seat 1 to the wheelchair.
[0036]
In addition, this toilet device does not require a locking mechanism for maintaining a horizontal state, as compared with the conventional toilet device configured to push up the toilet seat by the spring force of the spring, and the lifting force This is advantageous in that a mechanism for changing the mounting position of the spring member is not necessary to adjust the angle. In addition, there is an advantage that the toilet seat 1 can be stopped at any intermediate height position.
[0037]
In addition, the electric telescopic drive body 3 swings one parallel four-bar link 8 upward, and the biasing means 35 elastically biases the other parallel four-bar link 8 in the upward direction. The parallel four-bar links 8, 8 can be lifted and lowered in a balanced manner without causing any kneading, and the entire constituent members can be simplified. Further, the lateral connecting member 6 and the annular toilet seat 1 can increase the rigidity of the structure including the lateral connecting member 6, the toilet seat 1, and the left and right parallel four-joint links 8, 8, and can be raised and lowered and stopped. Occasionally, the toilet seat 1 can be prevented from wobbling or tilting left and right, and the safety is further improved.
[0038]
Further, the toilet seat 1 and the armrests 7 and 7 can be directly and detachably attached to the front link portions 11 and 11 of the parallel four-bar links 8 and 8, respectively. In that case, a recess 44 is provided at the upper end portion of the front link portion 11, bolt members 45, 45 are fixed, and a long mounting support portion 12 is fixed to the armrest 7 in the vertical direction.
[0039]
Next, FIG. 10 and FIG. 11 show another embodiment, and the armrest 7 is attached to the front link portion 11 so as to be able to be turned over and restored indirectly. Specifically, as shown in FIG. 10, the upper end portion of the attachment support portion 12 and the lower end portion of the attachment vertical member 46 of the armrest 7 are connected in the front-rear direction via the hinge mechanism 60 and the lock / release mechanism 61. It is connected so as to be switchable between a released state in which the armrest 7 can be turned around and a locked state in which the armrest 7 can be held in the retracted state, so that the armrest 7 can be rotated around the horizontal axis. Then, the armrest 7 can be turned sideways outward to a position lower than the toilet seat 1.
[0040]
As shown in FIG. 11, the lock / release mechanism 61 includes an attachment piece 62 fixed to the attachment support portion 12, a slide member 63 attached to the attachment piece 62 so as to be slidable in the front-rear direction, and an attachment vertical member 46. A locking piece 65 having a hole 64 into which the hemispherical tip of the slide member 63 is inserted and removably inserted, and a resilient member 66 that resiliently biases the slide member 63 toward the distal end. And comprising.
[0041]
When the slide member 63 is pulled in the proximal direction as indicated by the arrow G, the distal end portion is pulled out of the hole 64 and is released, and the armrest 7 is moved to the side as indicated by the arrow H in FIG. Can be defeated outward.
[0042]
Further, when the armrest 7 is raised as shown by the arrow I from the collapsed state, the tip of the slide member 63 of the lock / release mechanism 61 automatically enters the hole 64 and enters the locked state (see FIG. 11). ). Note that the armrest 7 may be attached to the front link portion 11 so that it can be directly turned over and restored. In that case, a hinge mechanism 60 and a lock / release mechanism 61 may be provided between the upper portion of the front link portion 11 and the lower portion of the attachment vertical member 46.
[0043]
Next, FIG. 12 and FIG. 13 show another embodiment, and the armrest 7 is attached to the front link portion 11 so as to be movable up and down indirectly. That is, as shown in FIG. 12, a mounting bracket 67 forming a vertical hole 68 is fixed to the upper portion of the mounting support 12, and the armrest 7 is attached to the square hole 68 formed by the mounting bracket 67. The vertical mounting member 46 is inserted from above. The armrest 7 can be lowered to a position substantially equal to the upper surface of the toilet seat 1.
[0044]
Thus, as shown in FIG. 12 and FIG. 13, a slide member 69 for locking and releasing is slidably attached to the mounting bracket 67, and a hemisphere of the slide member 69 is attached to the mounting vertical member 46. A plurality of hole portions 70 are inserted at predetermined pitches in the upper and lower directions so that the tip end portion is inserted so as to be freely inserted and removed. Further, a resilient member 71 for resiliently biasing the slide member 69 toward the tip is interposed between the mounting bracket 67 and the head at the tip of the slide member 69.
[0045]
With the above-described configuration, when the slide member 69 is pulled outward, the tip end portion can be removed from the hole portion 70 and the armrest 7 can be moved up and down. Also, if the arm rest 7 is slowly raised or lowered by releasing the hand from the slide member 69, the tip of the slide member 69 automatically enters the hole 70 and is locked to maintain the height of the arm rest 7 as it is. it can. Therefore, the height of the armrest 7 can be adjusted. In addition, if the armrest 7 is lowered to the lowest position, it does not get in the way when a seriously disabled person gets on and off. Further, the armrest 7 can be detached by pulling the mounting vertical member 46 upward from the square hole portion 68.
[0046]
The armrest 7 may be attached to the front link portion 11 so as to be directly movable up and down. In that case, the mounting bracket 67 is fixed to the outer surface on the upper side of the front link portion 11 to form the square hole portion 68, and the mounting vertical member 46 may be inserted into the square hole portion 68.
[0047]
14 and 15 show the toilet seat 1 with a toilet tub 81 detachably attached thereto. That is, in the toilet device of FIG. 14, L-shaped rail-like hook portions 80, 80 in front view are fixed to each other on the left and right sides of the lower surface of the toilet seat 1 so as to face each other. The toilet bowl 81 has an outer collar 81a at the upper edge. Then, the outer collar 81a of the toilet tub 81 is locked to the hooks 80 and 80.
