JP2000016370A - Power device capable of lightly traveling bicycle even in slope by rotating force of rotated lever - Google Patents

Abstract

PROBLEM TO BE SOLVED: To travel a bicycle with small force by a simple device by providing a power device capable of changing small force to large force by combining levers to be used. SOLUTION: Two same levers are used, and each one end of two levers is fitted to the common shaft. In this case, bearings of one end parts of two levers are formed as a one-way clutch structure so that when pushed, it is rotated, and when pulled, it is raced. The tip (force point) of each lever is connected to parts of both ends of a crankshaft rotated by a foot pedal through a pull rod. Thus, when the crankshaft is rotated by the foot pedal, two levers are alternately pushed and pulled repeatedly, whereby the rotation of the gear of the shaft rotated by small force is transmitted to a wheel throgh a transmission means such as a chain or the like by the principle of lever to travel a bicycle.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

In the past, the research and development of running a bicycle lightly has been carried out by using gears to combine a number of gears and various other methods, but it has reached the limit that there is no more. ing. At present, electric bicycles are on sale. This is a useful car that requires only half the power and is really convenient, but it has to be recharged all the time and the price is too high for running by human power, so anyone can buy it easily. Had a problem in that it was not.

[0002]

According to the present invention, the power is exerted by using only the gear as in the prior art, but the problem can be solved by using a lever. This is because even if the gears are combined, the rotation slows down, and if you try to increase the rotation, the power is lost and the problem cannot be solved. By increasing the number of levers and crankshafts to increase the rotation, the rotation can be increased without lowering the power of the first lever. Next, in the production process, two same levers are used, and both are coaxially mounted. The bearings (fulcrum) of the two lever rods rotate when they are pushed, and idle when pulled. Attach another pulling rod to the tip (power point) of the two levers and both ends of the crankshaft, and rotate the crankshaft by turning the attachment parts at both ends of the pulling rod lightly. Rotating movement in the same direction can be made by repeatedly pushing and pulling the lever lever. If the rotation is slow, increasing the same lever and crankshaft can increase the rotation without reducing the power, and can change the lever's power to a large rotational force, thus solving the problem.

[0003]

According to the present invention, a combination of levers can be used to change a large force with a small force, and the production cost can be reduced. In addition, it is economical because it is not necessary to purchase a new bicycle by making it possible to attach it by using the bicycle currently in use.

Claims (2)

[Claims] (1) Two levers are used, and both are coaxially mounted. Push both lever levers to rotate, and pull to allow idle rotation. Attach another pulling rod to the tip of the two levers and to both ends of the crankshaft, one at a time, so that the mounting part turns lightly. When the crankshaft is rotated, the two levers alternately push and pull. By repeating, rotational movement in the same direction can be performed. If the rotation is slow, increasing the lever and the crankshaft can increase the rotation without reducing the power, so that the power of the lever can be changed to a large rotational force. 2. A device that can be changed to a large rotating force by using a lever is set as a set so that it can be easily attached, and can be easily attached to a bicycle currently in use, and light even on a slope. Make it run. The method of claim 1.
