NEW SELF-PROPELLED WHEELCHAIR CAPABLE OF TRAVELING BY LITTLE ROTATION OF POWER ROTATING WHEEL TO GREATLY ROTATE POWER TIRE IN SELF-PROPELLING USING WHEELCHAIR
To solve a problem in the traveling using a self-propelled wheelchair in which conventionally a power tire may rotate and travel only as for a rotational amount of the kinetic power based on a rotational power wheel being rotated because the power tire and the rotational power wheel have a pair structure.SOLUTION: As before, in a self-propelled wheelchair, a power tire may rotate and travel only as for the rotational motion of a rotational power wheel, and therefore the rotational power wheel and the power tire are not made by a fixed pair structure but are separated so as to enable individual motion. A rotation center shaft of the rotational power wheel and the power wheel transmits rotational motion force to a gear 1 newly incorporating the gear in the power wheel rotation center shaft by a pair while converting rotation. The rotational motion force is transmitted from rotational power conversion gears 2-3 to a rotational outside shaft where a rotational outside shaft and a gear 4 become a pair at the outside of the power wheel rotation center shaft. Thereby, the rotational outside shaft is rotated and also a freewheel performs a similar rotational motion. Accordingly, the self-propelled wheelchair can be provided in which the rotational motion is transmitted to the power tire, and power tire spokes and the power tires are greatly rotated to travel forward.SELECTED DRAWING: Figure 1【課題】従来は、自走式車椅子を使って自走したとき回転動力輪を回した運動力の回転分しか動力タイヤと回転動力輪が一対構造のため動力タイヤは回転し進まなかった。【解決手段】 これまでのように自走式車椅子は回転動力輪の回転運動分しか動力タイヤは回転し進まなかったので、回転動力輪と動力タイヤを固定した一対作りとせず個別運動出来るように分離し、回転動力輪と動力輪回転中心軸は一対で動力輪回転中心軸に歯車を新たに組み込んだ歯車１に回転変換させながら伝え動力輪回転中心軸の外側に回転外軸と歯車４が一対となった回転外軸に回転動力変換歯車２－３から回転運動力を伝えることで回転外軸が回転しフリーホイールも同様の回転運動をする事で動力タイヤへ回転運動が伝わり、動力タイヤスポークと動力タイヤが大きく回転し進むことが出来る自走式車椅子を提供することが出来る。【選択図】図１
