Abstract
Description
本実施形態の介助ロボットの全体構成について、図1-図5を参照して説明する。介助ロボット1は、被介助者M1(図9,図10に示す)の体の一部(例えば、上半身)を支えて起立動作及び着座動作を補助する。介助ロボット1は、図1-図5に示すように、基台10、昇降アーム20,30、昇降部40、保持部50、アタッチメント60、昇降アクチュエータ70,80、前後動アクチュエータ90,100及び制御装置120を備える。以下の説明において、前後左右は、介助ロボット1の進行方向を前方としたときの前後左右とする。
制御装置120は、被介助者M1による操作に応じて、昇降アクチュエータ70,80、前後動アクチュエータ90,100を制御する。
アタッチメント60について図1-図5を参照して説明する。アタッチメント60は、本体部61、胴体パッド62、左右のグリップ63a,63b、左右の肘載置部64a,64b、左右の脇保持部65a,65b、及び、操作部66を備える。
本体部61は、保持部50の本体フレーム51に着脱可能に取り付けられる。
被介助者M1は、座位姿勢をとり、両手で脇保持部65a,65bをそれぞれ把持する。そして、被介助者M1は、脇保持部65a,65bを支点Cを中心に左右にそれぞれ旋回させ、脇保持部65a,65b間を拡開する。これにより、被介助者M1とグリップ63a,63bとの間の空間は、腕通過領域Aとして広く開放される。そして、被介助者M1は、両手を脇保持部65a,65bから離し、両腕を伸ばして腕通過領域A内における脇保持部65a,65bのU字の内側を通して両手でグリップ63a,63bをそれぞれ把持する。
なお、上述した実施形態では、脇保持部65a,65bは、下側に凹となる円弧状(U字形状)に形成したが、被介助者M1の脇に挟み込み可能な形状であればよい。例えば、図11の側面図に示すように、脇保持部68の上面68sのみがU字形状に形成されていればよい。また、図12の平面図に示すように、被介助者M1に対し脇保持部69の内側面69sが左右方向にそれぞれ凹となる円弧状に形成してもよく、これにより被介助者M1の背中側を保持可能となる。また、脇保持部65a,65bの形状を後方のみ立ち上がり部を有するL字形状としても良い。
また、脇保持部65a,65bには、引張コイルばね5を設ける構成としたが、一対の脇保持部65a,65bを縮閉する方向にそれぞれ付勢する弾性部材であればよく、例えば他の形態のばね(圧縮コイルばねやねじりコイルばね等)やゴム等でもよい。また、一対の脇保持部65a,65bを拡開する方向にそれぞれ付勢する弾性部材を設ける構成としてもよい。これにより、脇保持部65a,65bが開いた状態が原位置となるので、被介助者M1が介助ロボット1に乗り込む際に脇保持部65a,65bを開放する手間を省くことができる。
本実施形態の介助ロボット1は、基台10と、基台10に備えられ、被介助者M1の両脇をそれぞれ保持可能な一対の脇保持部65a,65bと、を備え、被介助者M1の起立動作又は着座動作を介助する。そして、一対の脇保持部65a,65bは、少なくとも被介助者M1の脇を保持する部位Sa,Sbよりも被介助者M1に対し奥側に設けられる支点Cを中心にそれぞれ旋回可能に設けられる。
また、一対の脇保持部65a,65bには、一対の脇保持部65a,65bを縮閉する方向にそれぞれ付勢する弾性部材5が設けられるので、被介助者M1は、被介助者M1の両脇を保持する部位Sa,Sbを被介助者M1の両脇の下の位置に容易に合わせられる。
また、一対の脇保持部65a,65bを縮閉する方向にそれぞれ付勢する弾性部材5に代えて、一対の脇保持部65a,65bに、一対の脇保持部を拡開する方向にそれぞれ付勢する弾性部材を設ければ、脇保持部65a,65bが開いた状態が原位置となり、被介助者M1が介助ロボット1に乗り込む際に脇保持部65a,65bを開放する手間を省くことができる。
また、脇保持部65a,65bには、支点Cとなる旋回ピン2と、案内ピン3が挿入されて旋回の案内となる長穴4と、が設けられるので、旋回のストロークを制限して必要以上に旋回しないようにできる。また、脇保持部65a,65bの旋回機構が簡易な構成となり、コスト高となることを抑制できる。
