NEW SELF-PROPELLED WHEELCHAIR CAPABLE OF TRAVELING BY LITTLE ROTATION OF POWER ROTATING WHEEL TO GREATLY ROTATE POWER TIRE IN SELF-PROPELLING USING WHEELCHAIR

摘要

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
