Claims (1)
- 上肢でハンドリムを操作することで前進・後退する車椅子の駆動輪に出力軸が結合され前記車椅子の前進方向に入力軸が駆動された場合にのみ駆動力を伝える一方向クラッチと、前記一方向クラッチの前記入力軸と一体に回転する前記車椅子の駆動軸の外周側に少なくとも部分的に巻かれた紐部材と、前記駆動軸の外周側に巻かれた前記紐部材の中央部分に対する一端側を前記駆動軸から離れる方向に牽引する牽引手段と、前記牽引手段による牽引により前記紐部材の前記中央部分に対する他端側が前記駆動軸方向に移動する移動を抑制する抑制手段と、を有する車椅子の駆動力自動解除式一方向回転駆動装置であって、
前記牽引手段は、車椅子のフレームに揺動自在に支承されたペダル支持フレームと前記ペダル支持フレームの一端に取り付けられたペダルと、を備え、
前記抑制手段は、前記紐部材の前記中央部分に対する他端側を引っ張った状態で車椅子のフレームに固定する引っ張りコイルバネを備え、
前記紐部材の長さは、前記ペダルを踏み込まない状態で緩みなく且つ前記紐部材と前記駆動軸との摩擦抵抗が略ゼロになるように選定されており、
前記牽引手段の牽引と前記抑制手段の抑制による前記駆動軸に巻き付く前記紐部材と前記駆動軸との間の摩擦抵抗によって前記牽引手段の牽引力で前記紐部材を介して前記駆動軸を前進方向に回転駆動し、前記牽引力がゼロになると前記摩擦抵抗もゼロになるため駆動力の伝達が自動的に解除されることを特徴とする車椅子の駆動力自動解除式一方向回転駆動装置。
