Abstract

<P>PROBLEM TO BE SOLVED: To provide a bicycle capable of reducing labor by utilizing a lever, a rotary disk, and a gear. <P>SOLUTION: Power is transmitted to the rotary disk and the gear by the vertical movement of the lever, to increase a labor saving effect larger than that of conventional crank type pedal rotary power. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

２本のてこ棒（図１−７、８）の各先端にペダル（図１−６）を取り付け途中に支点（図１−９）を付けて、てこ棒後方に接続棒（図１−１０）を取り付け、接続棒を、回転盤（図１−１１）に取り付ける。
てこ棒（図１−７）を踏み込む事により、てこ棒（図１−８）はシーソー棒（図３−１６）により上にあがり、てこ棒（図１−８）を踏み込めば、てこ棒（図１−７）は上にあがる。この繰り返しで回転盤（図１−１１）は回転し、回転盤が回転すると、歯車（図５−１７）も同時に回転し、この歯車に噛み合っている歯車（図５−１８）も回転し同時に歯車（図５−１２）も回転する、この歯車（図５−１２）よりチェーンにて後輪に接続され後輪が回転し、進行する。
てこ支点（図１−９）よりてこ先端ペダル（図１−６）迄の距離を長くすれば、力を得する事が大きく、また歯車（図５−１２、１７、１８）の組合せにより出力、速度も変える事ができる。
この考案により、てこ伝動装置は自転車以外にも運搬機などにも利用することが出来より利用価値の大きい物とした。

５前輪１０接続棒１５本体カバー２０接続棒フックAttach a pedal (FIG. 1-6) to the tip of each of the two lever bars (FIGS. 1-7 and 8), attach a fulcrum (FIG. 1-9) on the way, and connect a connecting rod (FIG. 1-10) behind the lever bar. ) Is attached, and the connecting rod is attached to the turntable (FIG. 1-11).
When the lever (FIG. 1-7) is depressed, the lever (FIG. 1-8) is lifted up by the seesaw bar (FIG. 3-16). FIG. 1-7) goes up. The revolving disk (FIG. 1-11) rotates by this repetition, and when the rotating disk rotates, the gear (FIG. 5-17) rotates at the same time, and the gear meshing with the gear (FIG. 5-18) also rotates and simultaneously. The gear (FIG. 5-12) also rotates. The gear (FIG. 5-12) is connected to the rear wheel by a chain, and the rear wheel rotates and proceeds.
If the distance from the lever fulcrum (FIG. 1-9) to the lever tip pedal (FIG. 1-6) is made longer, the force will be greater, and the output will be increased by the combination of gears (FIGS. 5-12, 17, 18). You can also change the speed.
With this idea, the lever transmission can be used not only for bicycles but also for transporters and the like, and has a greater utility value.
