Abstract

【課題】従来の自転車がクランクペダルで走行するのは基本的に駆動力を弱めると云う欠点があるので、長いペダルレバーを後輪に具えて上下往復運動によって高い効率で走行する自転車を提供する。【解決手段】先端にペダル２、２’、先端とは反対側の端部にフリーホイールを固着したレバー１と、前記レバーが左右に設備された後輪ハブと、該左右レバーに、各々バネ４、４’を装着し、夫々バネの他端を、車体後部に設備した構造になる。【選択図】図１The present invention provides a bicycle that travels with high efficiency by reciprocating up and down with a long pedal lever provided on the rear wheel because running a conventional bicycle with a crank pedal basically has the disadvantage of weakening the driving force. . A lever having a pedal attached to a tip thereof, a freewheel attached to an end opposite to the tip, a rear wheel hub provided with the lever on the left and right, and springs provided on the left and right levers. 4 and 4 'are attached, and the other ends of the springs are provided at the rear of the vehicle body.

Description

考案の詳細な説明Detailed description of the invention

本考案は左右の長い中空のペダルレバーをバネに支持されて、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 efficient driving force by reciprocating up and down with a long left and right hollow pedal lever supported by a spring.

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。さらに、拙者の実用新案登録３１１５８５３号による複雑な内歯車や歯車の連結によって、レバーの上下運動で走行する自転車は効率を弱める欠点を持っている。A conventional bicycle driven by a crank has a weak driving force and a heavy electric auxiliary drive device, which requires charging of a battery. Basically, a bicycle driven by a crank is inefficient. . Furthermore, due to the complicated connection of internal gears and gears according to my utility model registration No. 3115853, a bicycle running with the lever up and down has a drawback that the efficiency is reduced.

考案が解決しようとする課題Issues that the device is trying to solve

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、一定の人力では複雑な機構があると、効率を弱めることになる。  When a bicycle is reciprocated with a long pedal lever, the efficiency is higher than that of a crank motion. However, if there is a complicated mechanism with a constant human power, the efficiency is reduced.

課題を解決するための手段Means for solving the problem

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、さらに、内歯車に、平歯車を内接連結し、長い中空レバーの上下運動による機構に替え、長い中空ペタルレバーの元部位にフリーホイールを設備し、後輪ハブに連結し、夫々左右ペダルレバーを支持するバネを設けて車体本体部に据え付けて課題の解決を計る。  In order to solve the above-mentioned problems, instead of the crank mechanism of the conventional bicycle, a spur gear is inscribed and connected to the internal gear, and the mechanism is moved up and down by a long hollow lever. Freewheels are installed in the parts, connected to the rear wheel hubs, and springs that support the left and right pedal levers are provided and installed on the vehicle body to solve the problem.

考案の実施例Example of the invention

実施例について図面を参照して説明すると、図１に示すように中空の長いレバー（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（３）、（３’）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る。後輪主軸（５）に自在に回転するように嵌め合わされた後輪ハブの左右両側面にフリーホイール（３）、（３’）を据付け、左右のペダルレバーがそれぞれ上下運動すると、後輪ハブは一体となって回転することになる。さらに、後輪ハブはフリーホイール（６）を設備すると、後輪の前進回転はフリーとなって、より軽快に回転する。  The embodiment will be described with reference to the drawings. As shown in FIG. 1, pedals (2) and (2 ') are provided at the ends of long hollow levers (1) and (1'), and a freewheel ( 3) and (3 ') are mounted so that they are driven and rotated in the forward direction, and idle in the backward direction. The freewheels (3) and (3 ') are installed on the left and right sides of the rear wheel hub fitted so as to freely rotate on the rear wheel main shaft (5), and when the left and right pedal levers move up and down, respectively, the rear wheel hub. Will rotate together. Further, when the rear wheel hub is provided with a freewheel (6), the forward rotation of the rear wheel is free, and the rear wheel rotates more lightly.

考案の効果The effect of the invention

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複雑な機構の問題を除去した構成である。そしてベダルレバーに据え付けたバネ（４，４’）で、左右交互ばかりでなく、左右随意に上下運動を行えて、長い中空のペダルレバーが上下往復運動することで、高率な駆動力を得る自転車が提供される。  According to the present invention, a driving force that cannot be obtained with a conventional bicycle using a crank can be obtained by the above-described configuration and the embodiment, and a problem of a complicated mechanism when a pedal lever is provided is eliminated. The spring (4, 4 ') installed on the pedal lever allows not only alternating left and right, but also up and down movement freely, and a long hollow pedal lever reciprocates up and down to obtain a high rate of driving force. Is provided.
