DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a highly efficient bicycle that runs lightly with a small driving force by using a long wheel and a plurality of long chains and a chain wheel by linear reciprocating motion and utilizing the characteristics of a freewheel. .

[0002]

2. Description of the Related Art A conventional bicycle driven by a crank has a low body power and a complicated auxiliary driving device by electric power.

[0003]

When a bicycle is reciprocated by elongating a pedal lever, or when the bicycle is linearly moved up and down by a linear sliding pedal, rotation of a rear wheel is required unless a vertical distance is longer than that of a crank. There is a disadvantage that the number is small. In order to improve this point, it is necessary to have a long chain motion stroke even in vertical reciprocation or linear motion.

[0004]

Means for Solving the Problems In order to solve the above problems, a conventional bicycle is provided with a freewheel provided on a crankshaft by removing a crank, or a rear wheelset provided with left and right freewheels on a rear wheel vehicle. The pedal levers are freely connected directly from the left and right, and at least four chain wheels are installed on this pedal lever, and at least six chain wheels are mounted on the frame alternately so as to be aligned with this chain wheel. The chain wheel at the upper front corresponding to the tip of the pedal lever or the chain wheel at the uppermost front row of the frame is a freewheel. From the freewheel of the rear wheel, the chain car at the upper rear of the frame, the chain car at the rear of the pedal lever, the chain car at the middle of the next frame, the next car at the pedal lever, the freewheel chain car at the upper front of the frame,
The chain is sequentially connected to the chain vehicle at the lower front part of the frame by chain, and finally connected to the chain adjustment vehicle and connected to the freewheel of the rear wheel axle to connect the chain. The left and right pedal levers are connected to each other by a link or a cable through a universal wheel. Now, if you pedal with your left foot and push down the pedal lever, the pedal lever chain wheel will be pushed down, and the chain will move up to twice as long as the pedal lever has moved. With a plurality of these chain cars, a single push down will move the chain several times, so the freewheel of the rear wheel will make a large rotation. The link or cable raises the pedal lever on the right foot, and then rows down with the right foot, and the chain travels a long stroke as if rowing with the left foot. Since the pedal lever is connected to the rear wheel axle and is long, a long driving distance of the chain can be obtained even with a small driving force and a short vertical reciprocating stroke. Also, a linear axis is provided on the left and right, and a linear sliding pedal is engaged with the linear axis so as to move up and down. Two chain wheels are installed on this linear pedal, and four chain wheels are fixedly installed on the frame. Of which, the front upper part is connected as a freewheel chain car to the freewheel provided on the rear wheel axle by a chain as described above, and connected to the freewheel provided on the rear wheel axle. Chains can exercise long journeys.

[0005]

[Operation] When the chain wheel provided on the pedal lever is depressed, the chain wheel on the rear and middle portions of the frame and the chain wheel on the middle and front portions are depressed when the pedal lever is pressed down.
The front upper chain car is freewheel and stops so that the chain does not move when the pedal lever is depressed, so the chain pulls in the chain while rotating the freewheel on the rear wheel axis, and the length of movement of the chain Although the distance is twice as long in the calculation of the length of depression of the pedal lever, this ratio varies depending on the interval between the upper chain wheels provided on the frame. Now, if the chain wheel at the front of the pedal lever was pushed down 30 cm, the chain would have moved 1.6 times that distance, and the chain wheel at the rear and middle pedal lever would move only a shorter distance than the chain wheel at the tip. The ratio also changes depending on the distance between the chain wheels provided on the actual pedal lever. However, assuming that the chain moves 80% of the length of the chain wheel at the tip end, By the above calculation, the chain moves by 86.4 cm, which is 2.88 times 30 cm. In a conventional bicycle, the crank pedal is about 17 cm. One rotation is 17 cm × 2 × 3.14 = 106.8 cm, and the movement of one foot is half a rotation, which is 53.4 cm. Three
The chain moves 53.4cm with 4cm movement, so 1.5
7 times. Furthermore, the length of the crank pedal is 17cm
Making it longer causes inconvenience in running. On the other hand, the present device can tolerate a length of about 60 cm by freely coupling the pedal lever to the rear wheel axle, and is comparable to a conventional bicycle with a driving force of about 1/12. However, in this device, even if it is deemed that a driving force about four times that of a conventional bicycle is necessary, a power of about one third is sufficient, so that a bicycle that runs lightly with surprisingly high efficiency is provided.
