前記両足のそれぞれの足部と接続され、使用者の両脚のそれぞれの近傍に沿って延びる左右の脚部と、
使用者の腰の近傍に設けられ、前記左右の脚部をそれぞれ個別に回転可能に支持すると共に、前記左右の脚部をそれぞれ正転又は逆転させる左右のモータを有する腰部と、
一方の前記足部の裏面の曲面に沿って地面を捉えながら、前記一方の足部と接続された一方の脚部とは反対側の他方の前記脚部を蹴り出し時には正転させ、振り出し時には逆転させるように前記腰部の前記モータの正転又は逆転を制御する制御部と、
を備え、

前記両足のそれぞれの足部と接続され、使用者の両脚のそれぞれの近傍に沿って延びる左右の脚部と、
使用者の腰の近傍に設けられ、前記左右の脚部をそれぞれ個別に回転可能に支持すると共に、前記左右の脚部をそれぞれ正転又は逆転させる左右のモータを有する腰部と、
一方の前記足部の裏面の曲面に沿って地面を捉えながら、前記一方の足部と接続された一方の脚部とは反対側の他方の前記脚部を蹴り出し時には正転させ、振り出し時には逆転させるように前記腰部の前記モータの正転又は逆転を制御する制御部と、
を備え、
前記左右の足部の裏面の曲面に沿って地面を前記左右の足部の裏面で地面を交互に捉える受動歩行機構による歩行を実現する。
本発明者は、下肢支援装具の軽量化を図るため、膝部及び腰部のそれぞれに設けるアクチュエータの一方を省略することを検討した。この場合、膝部と腰部のアクチュエータの機能を考慮すると、腰部のアクチュエータが必須と考えられる。しかし、腰部のアクチュエータのみとした場合、脚部の蹴り出しと振り出しはできても、膝部のアクチュエータを省略したために、膝から下のアクティブな制御ができず、それだけではスムーズに全身を前進又は後退させることは困難なことを見出した。
図1は、実施の形態1に係る下肢支援装具10の概略を示す概略図である。図2は、実施の形態1に係る下肢支援装具10の構成を示すブロック図である。図3は、実施の形態1に係る下肢支援装具の制御部16の構成の一例を示すブロック図である。
左右の足部11a、11bのそれぞれの裏面には地面を捉える曲面12a、12bが設けられている。この裏面12a、12bの曲面に沿って地面を捉えることができるので、歩行イメージを自然なものとすることができる。図4は、図1の足部の裏面の曲面の曲率半径Rの様々な例を示す概略図である。この曲面12a、12bの曲率半径Rは、例えば、使用時の重心30から足部11(11a、11b)の裏面12までの距離R1以下であってもよい。さらに、曲率半径Rは、使用者の足首32から足部11(11a、11b)の裏面12までの距離R2以上であってもよい。また、曲率半径Rは、上記の他、例えば、膝部18から足部11(11a、11b)の裏面12(12a、12b)までの距離R3、脚部13(13a、13b)と腰部14との接続箇所から足部11(11a、11b)の裏面12(12a、12b)までの距離R4であってもよい。なお、図4に示すように、曲率半径Rの大きさに対応して、足部11の裏面12の厚さが変化する。
上記のように、裏面に設ける曲面の曲率半径を使用時の重心から裏面までの距離R1以下の長さを曲率半径Rとすることによって、エネルギー効率を向上させることができる。また、足部11a、11bの表面側には使用者の足を載せる。この場合、表面側は、適宜、足を載せるのに適した形状等にしてもよい。
左右の脚部13a、13bは、両端を両足のそれぞれの足部11a、11bと腰部14とにそれぞれ接続されている。また、脚部13a、13bは、使用者の両脚のそれぞれの近傍に沿って延びている。さらに、脚部13a、13bは、足部側の下部脚部17a、17bと、腰部側の上部脚部19a、19bと、下部脚部17a、17bと上部脚部19a、19bとを屈曲可能に接続する膝部18a、18bと、を有してもよい。また、膝部18a、18bは、下部脚部17a、17bが膝部18を中心として前方に向かう回転を抑止する逆転防止機構(図示せず)を備えてもよい。これによって、この下肢支援装具10が、使用者の膝では実現できない膝の逆転状態に陥らないようにすることができ、安全に使用できる。
腰部14は、使用者の腰の近傍に設けられ、左右の脚部13a、13bをそれぞれ個別に回転可能に支持する。また、腰部14には、左右の脚部13a、13bをそれぞれ正転及び逆転させる左右のモータ15a、15bを有する。モータ15a、15bは、正転及び逆転が可能なモータであればよい。制御部16は、一方の足部11a(11b)の裏面12a(12b)の曲面に沿って地面を捉えながら、その一方の足部11a(11b)と接続された一方の脚部13a(13b)とは反対側の他方の脚部13b(13a)の蹴り出し時には正転、あるいは振り出し時には逆転させるように腰部14のモータ15b(15a)の正転及び逆転を制御する。
また、上記の左右の足部11a、11bの裏面12a、12bで接地する際に、裏面12a、12bの曲面に沿って地面を連続的に捉えるようにすれば、歩行をさらに円滑に行うことができ、受動歩行の効果をより得やすくなる。
なお、左右の足部11a、11bの裏面12a、12bの曲面において、土踏まずに相当する部分のみを接地することにより、間欠接地を行うことも可能である。この場合、歩行の円滑性は劣るものの、上記説明と同様の受動歩行の効果を得ることができる。
あるいは、裏面12a、12bにおいて、一つの曲面ではなく、複数の曲面を設け、各曲面の凸部からなる仮想的な曲面で接地するようにしてもよい。この場合、各曲面の凸部での間欠的な接地を順に行うようにすることで、歩行を円滑に行うことができ、受動歩行の効果も得ることができる。また、各曲面の凸部で点接触によって接地するので地面からの影響を受けにくくすることができる。
