Description
【0001】[0001]
この考案は、人力によって推進力等を発生する自転車に関するものである。 The present invention relates to a bicycle that generates propulsive force and the like by human power.
【0002】[0002]
従来、主に足でペダルを漕ぐことによって推進力を発生させる場台、椅子に座 るような姿勢、すなわちサドル(1)がペダルの回転軸(2)より後方に位置す る関係で人間とペダルが設置されているものがあった。 Conventionally, when a person uses a foot to generate propulsive force mainly by pedaling, he or she sits on a chair, that is, because the saddle (1) is located behind the rotation axis (2) of the pedal. Some had pedals installed.
【0003】[0003]
これには次のような欠点があった。 (イ)従来の自転車では、漕ぐ人間とペダルの位置関係が、実用性を重視した位 置に設定されているため、高速あるいは強く漕ぐ時の運転姿勢は理想的では なかった。これは初期の自転車が実用性を重んじた開発・発展段階を歩んだ ためである。 (ロ)これにより、高い速度で巡行したり、強い加速度を得ようとする場合には 、サドルから乗り出し、人間とペダルの位置関係をより強い前傾姿勢に修 正する必要があった。 (ハ)このため不必要な体力が消費され、非常に疲れるものとなっていた。また 、着座したまま強く漕ぐと、太股の背面の腱など、体の局部に過度の負担 がかかり、傷害を引き起こす場合もあった。 本考案は、これらの欠点を除くためになされたものである。 This had the following drawbacks. (A) In conventional bicycles, the positional relationship between the person who pedals and the pedal is set in a position that places importance on practicality, so the driving posture when riding at high speed or strongly was not ideal. This is because the early bicycles went through a development and development stage that emphasized practicality. (B) As a result, when cruising at a high speed or trying to obtain strong acceleration, it was necessary to get out of the saddle and correct the positional relationship between the human and the pedal to a stronger forward leaning posture. (C) As a result, unnecessary physical strength was consumed and it became very tiring. In addition, if the person is strongly seated while rowing, excessive strain may be applied to local parts of the body such as the tendons on the back of the thigh, which may cause injury. The present invention has been made to eliminate these drawbacks.
【0004】[0004]
サドル(1)の真下付近、あるいはより後方にペダルの回転軸(2)を設置し 、その他の自転車の構成部品等とフレーム(5)により結合する。 本考案は、以上のような構成よりなる自転車である。 The rotation shaft (2) of the pedal is installed near the rear of the saddle (1) or at the rear of the saddle (1) and is connected to other components of the bicycle by the frame (5). The present invention is a bicycle configured as described above.
【0005】[0005]
これには以下の作用がある。 サドル(1)に座り、ハンドル(6)を握り、ペダル(7)(8)に足を乗せ ると、自動的に、従来の自転車に乗車してサドルから腰を浮かせた姿勢、つまり 強く漕ぐことができる姿勢をとることができる。 これにより、サドル(1)から腰を浮かせたり立ち上がる必要が無いまま体重 を有効に漕ぐ力に変換でき、全身の筋肉を偏りなく使うことができるため、無駄 な体力消費が抑えられ、長時間強く漕ぎ続けることができる。 This has the following effects. Sit on the saddle (1), grasp the handle (6), and put your foot on the pedals (7) and (8), and you will automatically ride on a conventional bicycle and lift your hips from the saddle, that is, paddle strongly. You can take the posture that you can. As a result, the weight can be effectively converted into the power to paddle without having to lift or stand up from the saddle (1), and the muscles of the whole body can be used without being biased. You can continue rowing.

以下、本案の実施例ついて説明する。 (イ)サドル(1)の真下付近、あるいはさらに後方にペダルの回転軸(2)を 設け、これらをフレーム(5)に設置する。 (ロ)前輪(3)などの部品をフレーム(5)に設置する。また後輪(4)はペ ダルの回転軸(2)の後方、または下方に設置する。ペダルの回転力はチェ ーン等を介して後輪(4)に伝えられる。 本案は以上のような構造で、この自転車に乗車した場合、サドル(1)に着座 しペダル(7)(8)に足を乗せただけで、自転車を漕ぐことに最も適する姿勢 、つまり従来の自転車ではサドルから立ち上がることによって作りだしていた姿 勢を自動的にとることができる。 そしてこの姿勢のまま着座しているため、自転車を漕ぐことに最も適する姿勢 を維持することができ、非常に体力消耗の少ない状態で高い速度で漕ぎ続けるこ とができる。 また第4図に示すように、後輪(4)の回転軸とぺダルの回転軸(2)を同軸 とすると、前輪(3)と後輪(4)の間隔が長くなりすぎず、旋回半径が小さく なり運転性能が向上する。 この場合、ペダル(7)(8)を漕ぐことによって発生する回転力は、プラネ タリーギヤ、内歯歯車等を介して後輪(4)に伝達するか、あるいは第4図に示 すように、チェーンあるいはベルト、ギヤ等により一旦後輪及びペダルの回転軸 とは異なる回転軸のスプロケット(9)あるいはギヤ等に伝達し、その後に後輪 (4)に伝達する方法等がある。 このとき、変速器を取り付ける場合、その位置は自由であり、後輪(4)側あ るいはスプロケット(9)側、出力側あるいは入力側などさまざまな方式が考え られる。 Hereinafter, examples of the present invention will be described. (A) A pedal rotation shaft (2) is provided near or below the saddle (1), and these are installed on the frame (5). (B) Parts such as the front wheel (3) are installed on the frame (5). The rear wheel (4) is installed behind or below the rotary shaft (2) of the pedal. The rotational force of the pedal is transmitted to the rear wheel (4) via a chain or the like. With the above structure, when the rider rides on this bicycle, he / she can sit on the saddle (1) and put his / her feet on the pedals (7) and (8), which is the most suitable posture for biking. With a bicycle, you can automatically take on the posture you were creating by standing up from the saddle. Since the person is still seated in this position, he / she can maintain the position most suitable for biking, and can continue to row at high speed with very little physical exhaustion. Further, as shown in FIG. 4, if the rotation axis of the rear wheel (4) and the rotation axis of the pedal (2) are coaxial, the distance between the front wheel (3) and the rear wheel (4) does not become too long, and the turning The radius is reduced and driving performance is improved. In this case, the rotational force generated by pedaling the pedals (7), (8) is transmitted to the rear wheel (4) via a planetary gear, an internal gear, or the like, or as shown in FIG. There is a method in which a chain, a belt, a gear or the like temporarily transmits to a sprocket (9) or a gear having a rotating shaft different from the rotating shafts of the rear wheel and the pedal, and then to the rear wheel (4). At this time, when the transmission is mounted, its position is free, and various methods such as the rear wheel (4) side or the sprocket (9) side, the output side or the input side can be considered.

以上のように本案の構造を持った自転車では、人間の体の特定の部位に過度の 負担をかけることなく、力を高効率で推進力に変換することができる。これによ り、より高い速度での走行が可能となるほか、強い加速力も得ることができる。 また漕ぐことによって身体に傷害を起こす危険性が大幅に低減される。 また自転車以外の場合でも、人間が脚力によって出力する物であれば、本案が 効果を発揮するため広い分野で応用できる。 As described above, the bicycle having the structure of the present invention can convert the force into propulsive force with high efficiency without imposing an excessive burden on a specific part of the human body. As a result, it is possible to drive at a higher speed and also obtain a strong acceleration force. In addition, the risk of injury to the body by rowing is greatly reduced. In addition, other than bicycles, as long as humans output by leg force, the present invention is effective and can be applied in a wide range of fields.
