Abstract
【課題】自転車の発進時の漕ぎ出し負荷を移動式ウェイト付タイミングベルトを使い漕ぐ力をアシストすることを提供する。【解決手段】自転車ペダルの軸を一体化したペダル（１）とタイミングプーリー（２・３・４）を使いタイミングベルトを掛けクランクが１回転した時にペダル側プーリー（２）も１回転することでベルトを回転させる動力が生まれウェイト付タイミングベルト（９）がクランクアームの角度によってウェイトの位置と回転周期を一定に移動することで漕ぐ時の負荷を軽減することができる。【選択図】図１PROBLEM TO BE SOLVED: To provide assisting a rowing force by using a timing belt with a mobile weight for a rowing load at the time of starting a bicycle. SOLUTION: A pedal (1) having an integrated bicycle pedal shaft and a timing pulley (2, 3, 4) are used to hang a timing belt, and when the crank makes one rotation, the pedal side pulley (2) also makes one rotation. Power to rotate the belt is generated, and the timing belt with weight (9) moves the position of the weight and the rotation cycle to a constant level depending on the angle of the crank arm, so that the load when rowing can be reduced.

Description
本発明は、自転車の漕ぎ出し負荷をウェイト付ベルトを回転させて運転者の脚力をアシストする事に関する。The present invention relates to assisting the driver's leg strength by rotating a weighted belt for the starting load of a bicycle.
従来の自転車は、発進時に脚力に負荷がかかるため変速ギアを使い発進を軽くしたりギア自体を小さな物にしたりして漕ぎ出し負荷を軽減するように構成されている。Since a load is applied to the leg force when starting a conventional bicycle, a transmission gear is used to lighten the start or the gear itself is made smaller to reduce the load of rowing.
従来の自転車は、変速や小型のギアを使うと軽く回転するがその分多く回転させなければ進まないが上記のテコの原理では、クランクアームの長さが変わると漕ぎにくくなりまた一定の動きの重りでは、左右の漕ぎ出し時に常にどちらかに負荷がかかる。A conventional bicycle rotates lightly when using gears or small gears, but it does not move unless it is rotated that much, but according to the above lever principle, it becomes difficult to row when the length of the crank arm changes and it moves constantly. With weights, a load is always applied to either side when rowing left or right.
本発明は、上述した課題を解決するために従来のペダルは、ペダル本体の軸が回転していたが本発明は、ペダル軸がペダルと一体式にする事でペダル（１）とプーリー（２）が連結して回転する動力を利用してウェイト付ベルトを動かしてクランクアームの角度の変化と同じにウェイトの位置が変わることで左右のペダルを漕ぎ出す時に常に適正な位置でウエイトが移動できるため右側ペダルを漕ぎ出す時は、クランクアーム先端にウエイトが移動して左側ペダルのクランクアームではクランク軸側にウェイトが移動する。In the present invention, in order to solve the above-mentioned problems, the shaft of the pedal body is rotated in the conventional pedal, but in the present invention, the pedal shaft is integrated with the pedal, so that the pedal (1) and the pulley (2) are integrated. ) Is connected and rotates to move the belt with weight, and the position of the weight changes in the same way as the angle of the crank arm changes, so that the weight can always move at the proper position when pedaling the left and right pedals. Therefore, when pedaling the right pedal, the weight moves to the tip of the crank arm, and the weight moves to the crank shaft side in the crank arm of the left pedal.
電動自転車ほどの効果は無いがペダルとプーリーを連結する事によって従来にない回転運動が得られる。Although it is not as effective as an electric bicycle, by connecting a pedal and a pulley, an unprecedented rotational movement can be obtained.
図２に示すようにタイミングベルト（８）は回転周期を一致させタイミングベルト（９）はベルトにウェイトが固定されている。 As shown in FIG. 2, the timing belt (8) has the same rotation cycle, and the timing belt (9) has a weight fixed to the belt.
またプーリーとベルトを交換してチェーン駆動にすればベルト駆動よりも幅を狭めることができる。Also, if the pulley and belt are replaced to drive the chain, the width can be narrower than that of the belt drive.
図１に示すようにペダル（１）とプーリー（２）を連結させて回転できるようにしてプーリー（３）は大・小２段プーリーになっており常にプーリー（２）からの動力で回転することができプーリー（４）は常に自由回転ができるように固定する。As shown in FIG. 1, the pedal (1) and the pulley (2) are connected so that they can rotate, and the pulley (3) is a large / small two-stage pulley, which always rotates with the power from the pulley (2). The pulley (4) can be fixed so that it can always rotate freely.
図１に示すようにプーリー（２）とプーリー（３）の小側にタイミングベルトを掛けプーリー（３）の大側とプーリー（４）にウェイト付タイミングベルトを掛けることによってペダル（１）が回転するとベルトが動くことができる。As shown in FIG. 1, a timing belt is hung on the small side of the pulley (2) and the pulley (3), and a weighted timing belt is hung on the large side of the pulley (3) and the pulley (4) to rotate the pedal (1). Then the belt can move.
