車いすを運転する時に、図３に示すタイヤと一体になっているタイヤハンドル を手で回し、タイヤを回転させて、前進・後退を行っている。坂道を上る時は、 タイヤハンドルより手を放すと、勝手に坂道を下ってしまうので手が放せない。 又、現状のブレーキ装置を使用すると、車いすは停止するが、その状態では前進 も後退もできない。 When driving a wheelchair, the tire handle integrated with the tire shown in Fig. 3 is turned by hand, and the tire is rotated to move forward and backward. If you release your hand from the tire handle when you go up a hill, you will not be able to release your hand because you will go down the hill without permission. If the current brake system is used, the wheelchair stops, but cannot move forward or backward in that state.

この発明は、図１（０７）に示すバネによりタイヤに固定されているリムと接 触させる（０１）部品を傾け（０１）にかける力の方向を変える事によりタイヤ の回転方向を一方向回転にさせるものである。 According to the present invention, the tire shown in FIG. 1 (07) is brought into contact with the rim fixed to the tire by the spring (01). It is what makes it.
【０００５】[0005]
考案実施の形態を図により説明すると、各部品の配置が図１の状態にあると、 （０１）はリムと接触しないのでタイヤは自由に回転するが、図２の状態にある 時は、（０１）は（０７）のバネにより矢印方向Ａへ押し上げられている。（０ １）は、（０３）の為に（０２）を支点として図２に示す矢印Ｂ方向へ回転しよ うとするのでリムと接触する。リムはＣ方向へ回転しようとする時には、（０１ ）部品と噛み込む状態になりＣ方向へは回転しない。又、矢印Ｃの逆方向へ回転 する時（０１）は、（０２）を支点として図２に示す矢印Ｂ方向と逆方向へ逃げ るので、リムと噛み込みの状態にはならずスムーズに回転する。 When the arrangement of each component is in the state of FIG. 1, the tire rotates freely because (01) does not contact the rim, but when in the state of FIG. 01) is pushed up in the arrow direction A by the spring (07). (01) comes into contact with the rim because it tries to rotate in the direction of arrow B shown in FIG. 2 with (02) as a fulcrum for (03). When trying to rotate in the C direction, the rim is engaged with the (01) component and does not rotate in the C direction. Also, when rotating in the direction opposite to arrow C (01), it escapes in the direction opposite to the direction of arrow B shown in FIG. 2 with (02) as a fulcrum. I do.

この考案により、車いすで坂道を上る時などタイヤハンドルより手を放しても 車は坂道を下らずに停止するので安全である。又、その状態を保ったままでタイ ヤを前進方向へのみ回転させることが出来るので、前進も可能である。 With this design, even if you release your hand from the tire handle, such as when going up a hill with a wheelchair, the car stops without going down the hill and is safe. In addition, the tire can be rotated only in the forward direction while maintaining that state, so that forward movement is possible.
