Description
本考案は左右の長い中空のペダルレバーを上下に往復運動することで、効率の良い駆動力によって軽快に走行する自転車に関する。 The present invention relates to a bicycle that travels lightly with an efficient driving force by reciprocating up and down long left and right hollow pedal levers.
従来のクランクによって走行する自転車は駆動力が弱く、又電動による補助駆動装置も重く、バッテリーの充電をしなければならず、基本的にクランクによって駆動する自転車は効率が良くないと云う欠点がある。 A conventional bicycle driven by a crank has a weak driving force, and an electric auxiliary drive device is heavy, and a battery must be charged. Basically, a bicycle driven by a crank has a disadvantage that it is not efficient. .
自転車においてペダルレバーを長くして往復運動した場合はクランク運動よりも効率は良くなるが、上下往復運動の距離を長く規定しなければ後部車輪の回転数が少ないと言う不具合が生じる。この点を改善するのには高効率を保ちながら後輪の回転比率を良くする必要がある。 When the bicycle is reciprocated with a long pedal lever in a bicycle, the efficiency is better than that of the crank motion. In order to improve this point, it is necessary to improve the rotation ratio of the rear wheels while maintaining high efficiency.
上記の諸課題を解決するために従来の自転車にあるクランク機構に換えて、元部にフリーホイールを具えた長い中空のペダルレバーを後輪主軸に自在に嵌め合わされたパイプに左右両端にフリーホイールで据え付けて、一方のペダルレバーの内側に内歯車を該パイプに固着し該内歯車に、平歯車を内接連結し、該平歯車に噛み合う遊び歯車を連結接続し、さらに該遊び歯車と噛み合い連結接続する平歯車は後輪と固着させてパイプと自在にはめ合うように設備する。左右のペダルレバーは自転車本体部に設けたプーリーに接続するベルトを介して連結する。該ベルトによって、ペダルレバーが上下往復するとフリーホイールによって左右交互に後輪主軸に嵌め合わされたパイプを自転車の前方向に回転させ、該パイプに固着している内歯車も前方に回転するので、該内歯車に内接して噛み合う平歯車も前方に回転する。該平歯車に噛み合う遊び歯車は後方向に回転し、該遊び歯車と噛み合っている後輪と固着している平歯車は前方に回転し、同じく後輪は前方に回転し自転車は走行する。内歯車の大きさと平歯車の歯数比によって、後輪の回転数が変化し、ペダルレバーの長さによって効率の良い駆動力が得られ中空のレバーは上下運動で車体本体部が障害とならないようになって課題の解決を計る。 In order to solve the above-mentioned problems, instead of the conventional crank mechanism, a long hollow pedal lever with a free wheel at the base is fitted to a pipe that is freely fitted to the rear wheel main shaft and free wheels at both left and right ends. The internal gear is fixed to the pipe inside one pedal lever, the spur gear is inscribed and connected to the internal gear, and the idler gear that meshes with the spur gear is connected and further engaged with the idler gear. The spur gear to be connected and connected is fixed to the rear wheel and installed so as to fit the pipe freely. The left and right pedal levers are connected via a belt connected to a pulley provided on the bicycle body. When the pedal lever reciprocates up and down by the belt, the pipe fitted to the rear wheel main shaft alternately by left and right by the free wheel is rotated in the forward direction of the bicycle, and the internal gear fixed to the pipe is also rotated forward. A spur gear inscribed and meshed with the internal gear also rotates forward. The idle gear meshing with the spur gear rotates in the rear direction, the spur gear fixed to the rear wheel meshing with the idle gear rotates in the forward direction, the rear wheel also rotates forward, and the bicycle runs. Depending on the size of the internal gear and the gear ratio of the spur gear, the number of rotations of the rear wheel changes, and an efficient driving force is obtained by the length of the pedal lever. Then we will solve the problem.
本考案は上記の構成、実施例によって従来のクランクによる自転車では不可能な駆動力を得ることが出来、又ペダルレバーを具えた場合の不具合な問題を除去した機構を装置して、長い中空のペダルレバーが上下往復運動することで自転車本体の障害となることなく高率な駆動力によって走行する自転車が提供される。 The present invention can provide a driving force that is impossible with a conventional bicycle with a crank according to the above-described configuration and embodiments, and is equipped with a mechanism that eliminates the problem of trouble when a pedal lever is provided. A bicycle that travels with a high driving force without obstructing the bicycle main body by the pedal lever reciprocating up and down is provided.
図面を参照して説明すると、図１に示すように上下に枠を設けて中空の長いレバー（１）、（１’）の先端にペダル（２）、（２’）を設けて元部にフリーホイール（７）、（７’）を前進方向に駆動回転し、後方向には空回りするように具え付けて、後輪主軸（１０）に自在に回転するように嵌め合わされたパイプ（１３）の左右両側面にフリーホイール（７）、（７'）を据付け、フリーホイール（７）の内側に内歯車（３）をパイプ（１３）に固着する。該内歯車（３）に内接して連結する平歯車（４）は遊び歯車（５）と接続連結し、該遊び歯車（５）は平歯（６）と接続連結し、該平歯車（６）は後輪（１２）と固着してパイプ（１３）に自在に回転するように嵌め合わされる。車体本体部（１１）によって、平歯車（４）及び遊び歯車（５）は支持されている。レバー（１）、（１’）は車体本体部（１１）に設けられたプーリー（８）によってベルト（９）を介して中間部で連結し、上下往復運動が可能となる。ペダル（２）を踏んでレバー（１）を押し下げるとフリーホイール（７）は前方向に回転するのでパイプ（１３）に固着している内歯車（３）は前方向に回転して駆動力を伝える。該内歯車（３）に内接連結している平歯車（４）は同じく前方向に回転し、遊び歯車（５）は後方向に回転するので、平歯車（６）は前方向に回転し、該平歯車（６）と固着する後輪（１２）は前方向に回転し、自転車は前進走行する。レバー（１）が押し下げられると、レバー（１’）はプーリー（８）でベルト（９）を介して押し上げられ、フリーホイール（７’）は空回りするので他には何も影響を与えない。次にペダル（２’）を踏んでレバー（１’）を押し下げると、フリーホイール（７’）は前方に回転してパイプ（１３）に固着している内歯車（３）を前方に回転させて、駆動力を伝え、該内歯車（３）に内接連結している平歯車（４）を同方向に回転させ、遊び歯車（５）を介して同じように平歯車（６）を前方向に回転させて、該平歯車（６）に固着している後輪（１２）を前方向に回転させ自転車は前方に走行する。この時レバー（１）は押し上げられるが、フリーホイール（７）は空転するので他に全く影響を与えない。このレバー（１）、（１’）の交互往復運動を繰り返すことで、駆動力を後輪（１２）に与えて自転車は前進走行する。 Referring to the drawings, as shown in FIG. 1, a frame is provided at the top and bottom, and a pedal (2), (2 ′) is provided at the tip of a hollow long lever (1), (1 ′), and the base part is provided. The free wheel (7), (7 ') is driven and rotated in the forward direction, and is provided so as to rotate freely in the rear direction, and the pipe (13) fitted so as to freely rotate on the rear wheel main shaft (10). Free wheels (7) and (7 ') are installed on the left and right side surfaces of the inner wheel, and an internal gear (3) is fixed to the pipe (13) inside the free wheel (7). The spur gear (4) inscribed and connected to the internal gear (3) is connected to the idle gear (5), the idle gear (5) is connected to the spur gear (6), and the spur gear (6 ) Is fitted to the rear wheel (12) so as to freely rotate to the pipe (13). The spur gear (4) and the idle gear (5) are supported by the vehicle body (11). The levers (1) and (1 ') are coupled at an intermediate portion via a belt (9) by a pulley (8) provided on the vehicle body main body (11), and can be reciprocated vertically. When the pedal (2) is depressed and the lever (1) is pushed down, the free wheel (7) rotates in the forward direction, so that the internal gear (3) fixed to the pipe (13) rotates in the forward direction to generate driving force. Tell. Since the spur gear (4) inscribed and connected to the internal gear (3) also rotates forward, and the idle gear (5) rotates backward, the spur gear (6) rotates forward. The rear wheel (12) fixed to the spur gear (6) rotates forward, and the bicycle travels forward. When the lever (1) is pushed down, the lever (1 ') is pushed up by the pulley (8) via the belt (9), and the free wheel (7') is idle, so that nothing else is affected. Next, when the pedal (2 ') is depressed and the lever (1') is pushed down, the free wheel (7 ') rotates forward, causing the internal gear (3) fixed to the pipe (13) to rotate forward. Then, the driving force is transmitted, the spur gear (4) inscribed in connection with the internal gear (3) is rotated in the same direction, and the spur gear (6) is moved in the same way via the idle gear (5). The rear wheel (12) fixed to the spur gear (6) is rotated in the forward direction, and the bicycle runs forward. At this time, the lever (1) is pushed up, but the free wheel (7) is idle so that it has no other effect. By repeating this reciprocating reciprocating movement of the levers (1) and (1 '), a driving force is applied to the rear wheel (12) and the bicycle travels forward.
レバーの長さと内歯車の大きさ、平歯車の歯車比を変化させることで、最適の自転車走行が可能となる。 By changing the length of the lever, the size of the internal gear, and the gear ratio of the spur gear, it is possible to travel optimally.
