Description

【０００１】
【発明の属する技術分野】
本発明は傷病者の歩行訓練を行う歩行訓練装置において用いられる吊具に関する。
【０００２】
【従来の技術】
歩行機能が失われたり、低下した傷病者に対しては、理学療法士の指導の下、歩行訓練が必要となる（本明細書においては歩行訓練を受ける傷病者を「被訓練者」と呼称し、理学療法士など、訓練担当のスタッフを「トレーナー」と呼称する）。歩行訓練を行うための装置、あるいは歩行訓練に使用できる装置はこれまでにも種々提案され、また実用化されている。特許文献１にそのような装置の例を見ることができる。
【０００３】
特許文献１に記載された装置では、身長より高い歩行器の上部より吊り下げたパラシュートハーネスにより被訓練者の身体を支持し、自力歩行させる。
【０００４】
【特許文献１】
特開２００２−３５０６５公報
【０００５】
【発明が解決しようとする課題】
特許文献１記載の装置のように、ハーネス型式の身体保持手段で被訓練者の身体を上から吊って支えることとすれば、被訓練者に支持バーを握らせたりさせる負担をかけることなく歩行訓練を行うことができる。しかしながら被訓練者の身体を吊って支える場合、従来の装置では次のような問題が発生していた。これを図６〜８に基づき説明する。
【０００６】
図６は従来の吊具及び身体保持手段にて被訓練者を支える状態を示す斜視図である。吊具４００は両端にフック状の連結部４０１を有する天秤棒状の部材であり、紐状部材４０２によって上方より懸垂支持（以下「吊支」の言葉を用いる）されている。被訓練者４１０の身体に装着される身体保持手段４１１は、被訓練者４１０の腰に巻くベルト４１２、股間を通して左右の大腿部に巻く２本のベルト４１３、及びベルト４１２より被訓練者４１０の胴体を前後から挟むように延び出す左右１対ずつ計４本の吊り紐４１４を組み合わせたものである。吊り紐４１４は連結部４０１に掛けるための輪状部分をそれぞれの端部に備える。
【０００７】
吊具４００は被訓練者４１０の真上に位置する。左側の２本の吊り紐４１４は左側の連結部４０１に連結し、右側の２本の吊り紐４１４は右側の連結部４０１に連結する。左側の２本の吊り紐４１４は被訓練者４１０の胴体の左部分を前後から挟み、右側の２本の吊り紐４１４は被訓練者４１０の胴体の右半分を前後から挟む形になる。
【０００８】
図示しない引上力発生装置が紐状部材４０２を介して吊具４００に所定の引上力を与え、被訓練者４１０の質量を見かけ上減少させる。このため被訓練者４１０は脚力が衰えていても立ち上がり、あるいは歩くことができる。
【０００９】
正常な歩行では腰部と肩部は逆方向に回旋する。これに対し図６の状態では、例えば左足を踏み出すため腰部を回旋して腰の左側を前方に突き出した場合、左側の２本の吊り紐４１４が前方に引かれる。この２本の吊り紐４１４は被訓練者４１０の胴体の左半分を前後から挟んでいるので、左肩は後ろ側を通る吊り紐４１４により前方に押し出される。つまり左足と左手が同時に前方に出る、いわゆる「ナンバ歩き」を強制される形になる。正常歩行とは手足の振り出しが異なり、歩きにくいし、このような不自然な歩き方は身につけない方が望ましい。
【００１０】
ベッドや椅子に腰掛けた体勢から立ち上がる訓練を行う際にも問題が生じる。図７は被訓練者４１０をベッドや椅子に腰掛けた体勢で吊り下げた状態を示す。このように腰掛け体勢から立ち上がる場合、胴体を前傾させて重心を足裏の上方延長上に移す必要がある。ところが吊り紐４１４が胴体を前後からぴったりと挟み、しかも上方に引上力が働いている状態では、図８のように胴体を前傾させようとしても肩が後ろに押し戻され、なかなか立つことができない。
【００１１】
本発明は上記のような問題点を解決するためになされたものであり、被訓練者の胴体の自然な動きを阻害しない歩行訓練用吊具を提供することを目的とする。
【００１２】
【課題を解決するための手段】
本発明の歩行訓練用吊具は次の構成を備える。
【００１３】
（１）被訓練者の腰に装着したベルトより被訓練者の胴体の前部を通って延び出す吊り紐を連結する前方連結部と、前記ベルトより被訓練者の胴体の後部を通って延び出す吊り紐を連結する後方連結部とを、被訓練者の胴体と吊り紐との間に隙間が生じるように前後方向に離して配置した。
【００１４】
この構成によれば、前後の吊り紐の間隔は吊具に近づくに従って広がり、被訓練者の胴体前後と吊り紐との間に隙間が生まれる。このため被訓練者は吊り紐に束縛されることなく胴体を動かすことが可能になる。胴体の動きが自由なので、正常歩行、すなわち腰部と肩部を逆方向に回旋させて同じ側にある手足を互いに逆方向に振り出す歩行を楽に行うことができる。
【００１５】
（２）上記のような歩行訓練用吊具において、歩行訓練装置に吊支される吊支連結部を設け、この吊支連結部から前記前方連結部まで前後方向距離を、この吊支連結部から前記後方連結部までの前後方向距離よりも長くした。
【００１６】
この構成によれば、被訓練者の胴体の前面側に特に大きなゆとりが生まれる。そのため前傾姿勢がとりやすく、立ち上がり訓練を無理なく行うことができる。また被訓練者は自身の前傾とともに吊具も前傾させることになるが、吊支連結部から前方連結部までの前後方向距離が吊支連結部から後方連結部までの前後方向距離よりも長いと吊具を前傾させるのに要する力が小さくて済み、立ち上がり訓練が一層容易になる。
【００１７】
（３）上記のような歩行訓練用吊具において、前記前方連結部と後方連結部の少なくとも一方は、複数のものを前記吊支連結部に対して異なる位置に配置した。
【００１８】
この構成によれば、吊支連結部に対し前後方向又は左右方向に位置の異なる前方連結部又は後方連結部のうち、いずれのものに吊り紐を掛けるかを選択することにより、被訓練者の身体の状況に合わせて、被訓練者の胴体の前後左右のゆとり、あるいは前後左右の吊り紐にかかる力の比率を調節することができる。
【００１９】
【発明の実施の形態】
以下、本発明の第１実施形態を図１〜４に基づき説明する。
【００２０】
図１は歩行訓練装置１の外観斜視図である。歩行訓練装置１はフレーム２を備え、フレーム２は垂直な柱状本体１０を倒れないように支持している。柱状本体１０の上端部からはアーム１２が水平に突き出す。アーム１２の内部には、アーム１２の長手方向に沿って直線的にスライドするスライダが設けられており、スライダは吊具５１を吊支する。柱状本体１０の正面下部には操作／表示部９２とコントローラ９３が設けられている。
【００２１】
図２は被訓練者を吊具５１で支える状況を示す斜視図である。吊具５１は天秤棒形状の横棒５１ａに平面形状矩形の枠５１ｂを固定した構造である。枠５１ｂのうち、横棒５１ａより前の部分はやや前下がりに傾斜している。
【００２２】
吊具５１は滑車ハウジング５３を介して吊支される。吊具５１は横棒５１ａの正面から見て中心部を上下に貫通するスイベル軸５３ａにより滑車ハウジング５３に連結され、滑車ハウジング５３の向きと無関係に水平面内で回転可能である。スイベル軸５３ａが吊具５１の吊支連結部となる。滑車ハウジング５３の内部には図示しない動滑車が設けられ、この動滑車に巻き掛けられた紐状部材５５により滑車ハウジング５３はスライダから吊り下げられ、上下可能になっている。
【００２３】
枠５１ｂの四隅には、被訓練者２１０から見て左前方の隅と右前方の隅とにフック状の前方連結部５２Ｆが、左後方の隅と右後方の隅とには同じくフック状の後方連結部５２Ｒが、それぞれ設けられる。これら２個ずつの前方連結部５２Ｆと後方連結部５２Ｒに、被訓練者２１０の身体を保持する身体保持手段２００を連結する。
【００２４】
身体保持手段２００は、被訓練者２１０の腰に巻くベルト２０１、股間を通して左右の大腿部に巻く２本のベルト２０２、及びベルト２０１から四方（被訓練者２１０の胴体の左前方、右前方、左後方、及び右前方）に延び出して前方連結部５２Ｆ及び後方連結部５２Ｒに個別に連結する４本の吊り紐２０３を組み合わせたものである。吊り紐２０３は前方連結部５２Ｆ又は後方連結部５２Ｒに掛ける輪状部分をそれぞれの端部に備える。
【００２５】
吊具５１において、前方連結部５２Ｆと後方連結部５２Ｒは、側面から見た場合、被訓練者２１０の胴体と吊り紐２０３との間に隙間が生じるように、前後方向に離して配置されている。相当程度厚みのある胴体であっても吊り紐２０３との間に隙間が生じるように、前方連結部５２Ｆと後方連結部５２Ｒとの前後方向間隔を設定する。吊支連結部（スイベル軸５３ａ）から前方連結部５２Ｆまでの前後方向距離（図３のＬ_１）は、吊支連結部から後方連結部５２Ｒまでの前後方向距離（図３のＬ_２）よりも長い。
【００２６】
続いて歩行訓練装置１の使用方法を説明する。
【００２７】
トレーナーは吊具５１を手で引き下ろし、被訓練者２１０に装着した身体保持手段２００の４本の吊り紐２０３のうち、被訓練者２１０の胴体の左前の吊り紐２０３は被訓練者２１０から見て左前にある前方連結部５２Ｆに、右前の吊り紐２０３は右前にある前方連結部５２Ｆに、左後の吊り紐２０３は左後にある後方連結部５２Ｒに、右後の吊り紐２０３は右後にある後方連結部５２Ｒに、それぞれ連結する。
【００２８】
上記のように４本の吊り紐２０３を吊具５１に連結した後、吊具５１から手を離せば、吊具５１は図示しない復元用錘による復元力で上昇し、吊り紐２０３はぴんと張る。紐状部材５５もぴんと張る。
【００２９】
錘によって与えられる所定の引上力が吊具５１を介して被訓練者２１０に伝わる。錘による引上力の生成については、本出願人の別出願に係る特願２００２−３２２０９９に、それに関する機構が開示されている。引上力により被訓練者２１０の質量は見かけ上減少し、脚部の負担が少なくなる。被訓練者２１０はトレーナーの指示に従い、スライダのスライド可能範囲とアーム１２の旋回可能範囲とにより区画される扇形の領域を歩き回る。
【００３０】
被訓練者２１０の胴体前後と吊り紐２０３との間には隙間が生じており、被訓練者２１０は吊り紐２０３に束縛されることなく胴体を動かすことができる。そのため、正常歩行、すなわち腰部と肩部を逆方向に回旋させて同じ側にある手足を互いに逆方向に振り出す歩行を楽に行うことができる。
【００３１】
また歩行訓練装置１を用いて、被訓練者２１０がベッドや椅子に腰掛けた姿勢から立ち上がる、立ち上がり訓練も行うことができる。図３は被訓練者２１０をベッドや椅子に腰掛けた体勢で吊り下げた状態を示す。
【００３２】
前述のように、吊支連結部（スイベル軸５３ａ）から前方連結部５２Ｆまでの前後方向距離Ｌ_１が、吊支連結部から後方連結部５２Ｒまでの前後方向距離Ｌ_２よりも長くなっているので、被訓練者２１０の胴体の前面と吊り紐２０３との間には十分な隙間が生じている。立ち上がろうとする被訓練者２１０は図４のように吊り紐２０３に邪魔されることなく胴体を深く前傾させることができ、重心を足裏の上方延長上に移して立ち上がる動作を簡単に行える。
【００３３】
被訓練者２１０が前傾の姿勢をとると、吊具５１が下がる。図３のＢ点における下向きの力Ｆ_ＢとＣ点における下向きの力Ｆ_Ｃの合力が引上力Ｆ_Ａに打ち勝って吊具５１が下がるのであるが、Ｆ_Ｂを生じさせようとすると胴体は上に引かれる。そのため、Ｆ_Ｂが大きいと前傾姿勢がとりにくい。Ｆ_Ｃは被訓練者２１０の体重で引く力なので問題とはならない。
【００３４】
Ｃ点を支点とすると、上下方向の力の釣り合いは次式のようになる。
【００３５】
【数１】

【００３６】
Ｌ_１／Ｌ_２が大きくなるとＦ_Ｂは小さくなる。従って、吊支連結部から前方連結部５２Ｆまでの前後方向距離が吊支連結部から後方連結部５２Ｒまでの前後方向距離よりも長ければ、それだけ吊具５１を前傾させるのに要する力が小さくて済み、立ち上がりが容易になる。
【００３７】
Ｌ_１／Ｌ_２の値は１．５〜３の範囲内にあるのが望ましい。ここではＬ_１／Ｌ_２＝２とした。被訓練者２１０の身体の状況によっては上記範囲をはみ出す値を設定してよく、Ｌ_２の方をＬ_１より長くしても構わない。
【００３８】
また吊具５１を正面から見た場合、吊支連結部から前方連結部５２Ｆ又は後方連結部５２Ｒまでの左右方向における距離は、必ずしも左右均等である必要はない。これも被訓練者の身体の状況に応じ、左右不均等に設定することができる。
【００３９】
次に、本発明の第２実施形態を図５に基づき説明する。
【００４０】
図５は吊具５１の上面図である。この吊具５１には、枠５１ｂの四隅以外にも前方連結部５２Ｆと後方連結部５２Ｒを有する。すなわち、平面形状矩形の枠５１ｂの中で、正面から見て左側の辺を構成する縦棒と右側の辺を構成する縦棒には、枠５１ｂの四隅以外の箇所に、前方連結部５２Ｆと後方連結部５２Ｒを２個ずつ配置する。片側２個の前方連結部５２Ｆは、吊支連結部より前方にして、吊支連結部からの前後方向距離の異なる２箇所に配置されている。同様に片側２個の後方連結部５２Ｒは、吊支連結部より後方にして、吊支連結部からの前後方向の異なる２箇所に配置されている。
【００４１】
また、枠５１ｂの中で前方の辺を構成する横棒と後方の辺を構成する横棒にも、枠５１ｂの四隅以外の箇所に、前方連結部５２Ｆと後方連結部５２Ｒを６個ずつ配置する。片側３個の前方連結部５２Ｆは、吊支連結部の左又は右において、吊支連結部からの左右方向距離の異なる３箇所に配置されている。同様に片側３個の後方連結部５２Ｒは、吊支連結部の左又は右において、吊支連結部からの左右方向距離の異なる３箇所に配置されている。
【００４２】
第２実施形態の吊具５１は上記のように構成されているので、吊支連結部からの前後方向距離の異なる前方連結部５２Ｆ及び後方連結部５２Ｒのうち、いずれのものに吊り紐２０３を掛けるかを選択することにより、被訓練者２１０の胴体の前後のゆとり、あるいは前後の吊り紐２０３にかかる力の比率を調節することができる。また吊支連結部からの左右方向距離の異なる前方連結部５２Ｆ及び後方連結部５２Ｒのうち、いずれのものに吊り紐２０３を掛けるかを選択することにより、被訓練者２１０の胴体の左右のゆとり、あるいは左右の吊り紐２０３にかかる力の比率を調節することができる。
【００４３】
すなわち第２実施形態の吊具５１を用いれば、被訓練者２１０の身体の状況に合わせて、被訓練者２１０の胴体の前後左右のゆとり、あるいは前後左右の吊り紐２０３にかかる力の比率を自由に設定できる。なお、前方連結部５２Ｆ及び後方連結部５２Ｒの数の設定、及び前後左右における配置ピッチの設定は任意である。前方連結部５２Ｆと後方連結部５２Ｒの一方についてのみ枠５１ｂの四隅以外への増設を図り、他方は増設しない構成とすることも可能である。
【００４４】
また吊具５１の枠５１ｂに横棒を追加し、この追加した横棒を利用して前方連結部５２Ｆ、後方連結部５２Ｒを増設してもよい。
【００４５】
以上本発明の実施形態につき説明したが、この他、発明の主旨を逸脱しない範囲で様々な変更を加えて実施することができる。
【００４６】
【発明の効果】
本発明の歩行訓練用吊具では、被訓練者の胴体前後と身体保持手段の吊り紐との間に隙間が生じるので、被訓練者は吊り紐に束縛されることなく胴体を動かし、正常歩行、すなわち腰部と肩部を逆方向に回旋させて同じ側にある手足を互いに逆方向に振り出す歩行を行うことができる。また、歩行訓練装置に吊支される吊支連結部から前方連結部までの前後方向距離を、吊支連結部から後方連結部までの前後方向距離よりも長くすることにより、被訓練者の胴体の前面側に特に大きなゆとりを生じさせ、前傾姿勢をとりやすくすることができる。同時に、吊具を前傾させるのに要する力が小さくて済むこととなり、立ち上がり訓練が一層容易になる。さらに、前方連結部と後方連結部の少なくとも一方は、複数のものを吊支連結部に対して異なる位置に配置することとし、吊支連結部に対し前後方向又は左右方向に位置の異なる前方連結部又は後方連結部のうち、いずれのものに吊り紐を掛けるかを選択できるようにすることにより、被訓練者の身体の状況に合わせて、被訓練者の胴体の前後左右のゆとり、あるいは前後左右の吊り紐にかかる力の比率を調節することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a hanger used in a walking training device that performs walking training for a patient.
[0002]
[Prior art]
For a patient who has lost or deteriorated walking function, walking training is required under the guidance of a physiotherapist. (In this specification, a patient receiving walking training is referred to as a "trainee." And training staff, such as physiotherapists, are called "trainers." Various devices for performing walking training or devices that can be used for walking training have been proposed and put into practical use. An example of such a device can be found in US Pat.
[0003]
In the device described in Patent Literature 1, a trainee's body is supported by a parachute harness suspended from an upper part of a walker whose height is higher, and the trainee walks on his own.
[0004]
[Patent Document 1]
JP-A-2002-35065
[Problems to be solved by the invention]
If the trainee's body is hung from above and supported by the harness-type body holding means as in the device described in Patent Document 1, walking can be performed without imposing a burden on the trainee to grip the support bar. Training can be performed. However, when the trainee's body is suspended and supported, the following problems have occurred in the conventional device. This will be described with reference to FIGS.
[0006]
FIG. 6 is a perspective view showing a state in which a trainee is supported by a conventional hanging device and body holding means. The hanging member 400 is a balance bar-shaped member having hook-shaped connecting portions 401 at both ends, and is suspended from above by a string-shaped member 402 (hereinafter, the term “hanging member” is used). The body holding means 411 attached to the body of the trainee 410 includes a belt 412 wound around the waist of the trainee 410, two belts 413 wound around the right and left thighs through the crotch, and the belt 412. A total of four hanging strings 414 are combined, each pair of right and left extending so as to sandwich the body from front and rear. The hanging string 414 has a loop-shaped portion at each end for hanging on the connecting portion 401.
[0007]
The hanging device 400 is located directly above the trainee 410. The two left suspension strings 414 are connected to the left connection section 401, and the two right suspension strings 414 are connected to the right connection section 401. The two hanging strings 414 on the left side sandwich the left part of the body of the trainee 410 from front and back, and the two hanging strings 414 on the right side sandwich the right half of the body of the trainee 410 from front and back.
[0008]
A lifting force generator (not shown) applies a predetermined lifting force to the hanging device 400 via the string-shaped member 402, and apparently reduces the mass of the trainee 410. Therefore, the trainee 410 can stand up or walk even if his / her leg strength is weakened.
[0009]
In normal walking, the waist and shoulders rotate in opposite directions. On the other hand, in the state of FIG. 6, for example, when the waist is rotated to step on the left foot and the left side of the waist is projected forward, the two hanging strings 414 on the left side are pulled forward. Since these two suspension strings 414 sandwich the left half of the body of the trainee 410 from the front and rear, the left shoulder is pushed forward by the suspension string 414 passing through the rear side. In other words, the left foot and the left hand are simultaneously forced to go forward, so-called “number walking”. It is difficult to walk because the swing of the limbs is different from normal walking, and it is desirable not to wear such an unnatural way of walking.
[0010]
Problems also arise when training to stand up from a bed or chair. FIG. 7 shows a state where the trainee 410 is suspended in a posture of sitting on a bed or a chair. When the user stands up from the stool position, it is necessary to tilt the torso forward to shift the center of gravity to the upward extension of the sole. However, in a state where the suspending string 414 sandwiches the torso tightly from the front and back, and a pulling force is acting upward, even if the torso is tilted forward as shown in FIG. 8, the shoulder is pushed back and it is difficult to stand. Can not.
[0011]
The present invention has been made in order to solve the above problems, and has as its object to provide a walking training hanger that does not hinder the natural movement of the trainee's torso.
[0012]
[Means for Solving the Problems]
The walking training hanger of the present invention has the following configuration.
[0013]
(1) A front connecting portion for connecting a suspension string extending through a front portion of the trainee's torso from a belt attached to the trainee's waist, and extending from the belt through a rear portion of the trainee's torso. The rear connecting portion for connecting the hanging string to be put out was arranged in the front-rear direction so that a gap was formed between the body of the trainee and the hanging string.
[0014]
According to this configuration, the distance between the front and rear suspension strings is increased as approaching the suspender, and a gap is created between the front and rear of the trainee and the suspension string. Therefore, the trainee can move the torso without being bound by the hanging string. Since the torso can move freely, normal walking, that is, walking in which the waist and the shoulder are turned in the opposite directions and the limbs on the same side are swung in the opposite directions can be easily performed.
[0015]
(2) In the above-described walking training hanger, a hanger connection part hung by the walking training device is provided, and a distance in the front-rear direction from the hanger connection part to the front connection part is determined by the hanger connection part. From the front to the rear connecting portion.
[0016]
According to this configuration, a particularly large space is created on the front side of the body of the trainee. Therefore, it is easy to take a forward leaning posture, and it is possible to perform the standing training without difficulty. In addition, the trainee also leans forward with his own forward tilt, but the distance in the front-rear direction from the suspension connection part to the front connection part is longer than the front-rear distance from the suspension connection part to the rear connection part. Longer lengths require less force to tilt the sling forward, making standing training easier.
[0017]
(3) In the walking training hanger as described above, at least one of the front connection part and the rear connection part has a plurality of things arranged at different positions with respect to the suspension support connection part.
[0018]
According to this configuration, by selecting which one of the front connection portion or the rear connection portion that is different in the front-rear direction or the left-right direction with respect to the suspension connection portion, the hanging string is hung on the trainee. It is possible to adjust the ratio of the force applied to the front and rear and left and right suspension strings of the trainee's torso or the front and rear and left and right suspension strings according to the physical condition.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
[0020]

The suspension string 203 has a ring-shaped portion to be hung on the front connection portion 52F or the rear connection portion 52R at each end.
[0025]
In the hanging device 51, the front connecting portion 52F and the rear connecting portion 52R are spaced apart in the front-rear direction so that a gap is formed between the body of the trainee 210 and the hanging string 203 when viewed from the side. I have. The front-rear distance between the front connecting portion 52F and the rear connecting portion 52R is set such that a gap is formed between the suspension string 203 and the body even if the body has a considerable thickness. The front-rear distance (L _{1 in} FIG. 3) from the suspension connection portion (swivel shaft 53a) to the front connection portion 52F is greater than the front-rear distance (L _{2 in} FIG. 3) from the suspension connection portion to the rear connection portion 52R. Is also long.
[0026]
Subsequently, a method of using the walking training device 1 will be described.
[0027]
The trainer pulls down the suspending tool 51 by hand, and among the four suspending strings 203 of the body holding means 200 attached to the trainee 210, the suspending string 203 on the left front of the body of the trainee 210 is viewed from the trainee 210. To the front connecting portion 52F at the left front, the right front hanging string 203 to the front connecting portion 52F at the right front, the left rear hanging string 203 to the rear connecting portion 52R at the left rear, and the right rear hanging string 203 to the right rear. Each is connected to a certain rear connecting portion 52R.
[0028]
After the four hanging strings 203 are connected to the hanging tool 51 as described above, if the hand is released from the hanging tool 51, the hanging tool 51 is raised by the restoring force of the restoring weight (not shown), and the hanging string 203 is taut. . The string-shaped member 55 is also stretched.
[0029]
A predetermined pulling force given by the weight is transmitted to the trainee 210 via the hanging tool 51. Regarding generation of a pulling force by a weight, a mechanism related thereto is disclosed in Japanese Patent Application No. 2002-322099 filed by the present applicant. Due to the pulling force, the mass of the trainee 210 is apparently reduced, and the burden on the legs is reduced. The trainee 210 walks around a fan-shaped area defined by the slidable range of the slider and the swivel range of the arm 12 according to the instruction of the trainer.
[0030]
There is a gap between the front and back of the trainee 210 and the suspension string 203, and the trainee 210 can move the trunk without being bound by the suspension string 203. Therefore, normal walking, that is, walking in which the waist and the shoulder are turned in the opposite directions and the limbs on the same side swing in the opposite directions can be easily performed.
[0031]
In addition, by using the walking training device 1, the trainee 210 can also perform a standing training in which the trainee 210 stands up from a posture sitting on a bed or a chair. FIG. 3 shows a state in which the trainee 210 is suspended in a posture of sitting on a bed or a chair.
[0032]
As described above, longitudinal distance L ₁ of Tsu支connecting portion from (swivel axis 53a) to the front connecting portion 52F is longer than the longitudinal distance L ₂ from Tsu支connecting portion to the rear connecting portion 52R Therefore, a sufficient gap is formed between the front surface of the body of the trainee 210 and the suspension string 203. As shown in FIG. 4, the trainee 210 who is trying to get up can lean his torso deeply forward without being hindered by the hanging string 203, and can easily perform the operation of shifting his center of gravity to the upward extension of the sole and standing up.
[0033]
When the trainee 210 takes a forward leaning posture, the hanging tool 51 is lowered. Although the resultant force of the downward force F _C in downward force F _B and the point C at point B in FIG. 3 is the suspender 51 is lowered by overcoming the pulling force F _A, and you make him produce F _B torso Pulled up. For this reason, F _B is large, the stoop is hard to take. F _C is not a problem because the forces that pull in the body weight of the trainee 210.
[0034]
Assuming that the point C is a fulcrum, the balance of the vertical force is as follows.
[0035]
(Equation 1)

[0036]
L ₁ / _{L 2} increases the _{F B} is reduced. Therefore, if the front-rear distance from the suspension connection portion to the front connection portion 52F is longer than the front-rear distance from the suspension connection portion to the rear connection portion 52R, the force required to tilt the hanger 51 forward is smaller. And start up becomes easy.
[0037]
The value of L ₁ / _{L 2} is desirably in the range of 1.5 to 3. Here, L ₁ / L ₂ = 2. May in some circumstances of the trainee 210 body to set the value protruding the above range, the direction of L ₂ may be longer than L _1.
[0038]
In addition, when the hanging tool 51 is viewed from the front, the distance in the left-right direction from the suspension connection portion to the front connection portion 52F or the rear connection portion 52R is not necessarily required to be equal in the left and right directions. This can also be set to be left and right unequal according to the physical condition of the trainee.
[0039]
Next, a second embodiment of the present invention will be described with reference to FIG.
[0040]
FIG. 5 is a top view of the hanging tool 51. The hanging tool 51 has a front connecting portion 52F and a rear connecting portion 52R in addition to the four corners of the frame 51b. That is, in the rectangular frame 51b of the planar shape, the vertical bar forming the left side and the vertical bar forming the right side when viewed from the front include the front connecting portion 52F at a position other than the four corners of the frame 51b. Two rear connecting portions 52R are arranged. The two front connection portions 52F on one side are disposed at two positions at different distances from the suspension connection portion in the front-rear direction, ahead of the suspension connection portion. Similarly, the two rear connection portions 52R on one side are arranged at two different positions in the front-rear direction from the suspension connection portion, behind the suspension connection portion.
[0041]
In the horizontal bar forming the front side and the horizontal bar forming the rear side in the frame 51b, six front connection portions 52F and six rear connection portions 52R are arranged at positions other than the four corners of the frame 51b. I do. The three front connection portions 52F on one side are disposed at left or right sides of the suspension connection portion at three different distances from the suspension connection portion in the left-right direction. Similarly, the three rear connection portions 52R on one side are disposed at left and right sides of the suspension connection portion at three different distances from the suspension connection portion in the left-right direction.
[0042]
Since the hanging device 51 of the second embodiment is configured as described above, the hanging string 203 is attached to any one of the front connecting portion 52F and the rear connecting portion 52R having different front-to-back distances from the hanging support connecting portion. By selecting whether to hang or not, it is possible to adjust the clearance between the front and rear of the body of the trainee 210 or the ratio of the force applied to the front and rear suspension strings 203. In addition, by selecting which one of the front connecting portion 52F and the rear connecting portion 52R, which are different from each other in the left-right direction distance from the suspension connecting portion, to hang the suspension string 203, the left and right clearance of the trainee 210's torso can be obtained. Alternatively, the ratio of the forces applied to the left and right suspension strings 203 can be adjusted.
[0043]
That is, if the hanging device 51 of the second embodiment is used, the ratio of the force applied to the hanging string 203 of the trainee 210 in the front-rear, left-right, or front-rear, left-right directions can be adjusted according to the physical condition of the trainee 210. Can be set freely. The setting of the number of the front connecting portions 52F and the rear connecting portions 52R, and the setting of the arrangement pitch in front, rear, left and right are arbitrary. Only one of the front connecting portion 52F and the rear connecting portion 52R may be added to other than the four corners of the frame 51b, and the other may not be added.
[0044]
Further, a horizontal bar may be added to the frame 51b of the hanging tool 51, and the front connecting portion 52F and the rear connecting portion 52R may be added using the added horizontal bar.
[0045]
Although the embodiments of the present invention have been described above, other various modifications can be made without departing from the gist of the present invention.
[0046]
【The invention's effect】
In the walking training hanger of the present invention, since a gap is formed between the front and rear of the trainee's torso and the hanging string of the body holding means, the trainee moves the torso without being bound by the hanging string, and can walk normally. That is, walking can be performed in which the waist and the shoulder are turned in the opposite directions, and the limbs on the same side are swung in the opposite directions. Also, by making the front-rear distance from the suspension connection part to the front connection part suspended from the walking training device longer than the front-rear distance from the suspension connection part to the rear connection part, the body of the trainee A particularly large clearance is generated on the front side of the vehicle, and it is easy to take a forward leaning posture. At the same time, the force required for tilting the hanger forward is small, and the standing training is further facilitated. Further, at least one of the front connection portion and the rear connection portion is configured such that a plurality of the front connection portions and the rear connection portions are arranged at different positions with respect to the suspension connection portions, and the front connection portions have different positions in the front-rear direction or the left-right direction with respect to the suspension connection portions. Of the trainee's torso, or the front and rear, or the front and back, according to the physical condition of the trainee The ratio of the forces applied to the left and right suspension strings can be adjusted.
