PROBLEM TO BE SOLVED: To provide a pedal-driven wheelchair which is simply structured and can turn in a small radius.SOLUTION: A pedal-driven wheelchair has running wheels for running on right and left sides of a seat and pedals to be driven by feet in front. A drive shaft which is rotated by the pedals is bridged laterally under the seat. Drive wheels are pivotally attached with right and left ends of the drive shaft. The running wheels arranged on the right and left sides of a car body are freely turnable idler wheels. The wheelchair runs with the drive wheels in contact with the right and left running wheels. The wheelchair is pivot turned by stopping one of the running wheels and rotating the other, by separating one drive wheel from the idler wheel for running opposed to the drive wheel while keeping the other drive wheel in contact with the other running wheels.COPYRIGHT: (C)2014,JPO&INPIT【課題】構造が簡単で、小旋回ができる足漕ぎ式車椅子を提供すること。【解決手段】座席の左右に走行用の走行車輪と、前方に足で駆動する足漕ぎペダルを持ち、座席の下方にペダルで回転する駆動軸を横架し、該駆動軸の左右端に駆動輪を軸着し、車体の左右に設けた走行車輪を回動自在な遊動輪とすると共に、該駆動輪を左右の走行車輪に接触させて走行すると共に、駆動輪の片方を片方の走行車輪と接触させたまま、他方の駆動輪をそれと対峙した走行用の遊動車輪から離すことにより、走行車輪の片方を止め、他方を回転させることにより、車椅子を信地旋回させること。【選択図】図1
