To solve the problem that it is difficult to drive a self-propelled wheelchair for a wheelchair user having extremity dysfunction (especially, functional difference between left and right, upper and lower limbs) such as disabled both hands.SOLUTION: In order to move a caster straight easily, and to secure some degree of rotation, a stretch material is used, to thereby impart straight directivity to the caster. As a method 1, the stretch material is wound directly around the caster and a frame. When the method 1 cannot be used due to a structure, as a method 2, an adapter for attaching the stretch material is attached to the caster (wheel), and thereby the stretch material is attached to the adapter and the frame.SELECTED DRAWING: Figure 11
【課題】両手が使えないなどの四肢機能障害(特に左右上下肢の機能差)を有す車いす使用者では、自走型車いすを駆動しにくい。【解決手段】車いすのキャスターを直進させやすく、ある程度の回旋性も確保するために、伸縮素材を使用し、キャスターに直進方向性をもたらした。方法1として伸縮素材を直接的、キャスターとフレームに巻く。構造上、方法1を用いることが出来ない場合、方法2として、キャスター(車軸)に伸縮素材を取り付けるためのアダプターを付け、アダプターとフレームに伸縮素材をつけるもの。【選択図】図11
