Description of the Related Art

During the period of 1867 to 1885, the development of bicycles in Western Europe has been gradually fixed and become a familiar appearance in the world today. In the past 130 years, although flywheels, chains, pneumatic tires, and transmission mechanisms have been invented to improve riding efficiency or comfort, the basic structure of bicycles has not undergone fundamental changes. The most ingrained element is the rotary pedaling prime mover.

As shown inFIGS. 9A-9C, it shows a schematic diagram of a conventional rotary pedaling prime mover at different pedaling angles, wherein R is the turntable lever arm, F is the pedaling force of a leg, A is the angle of forward rotation from the top dead center, B is the angle between the handle and the horizontal plane, B+A=90 degrees, Fø is the component of F in the direction parallel to R, F⊥ is F in the direction perpendicular to R, and the downward pedaling by gravity will produce a torque τ=F×R×sin(A), or τ=F×R×cos(B). Generally speaking, the effective torque applied to the pedal is only in the range of 90 degrees from 2 o'clock to 4 o'clock, and when the pedal reaches the 3 o'clock direction, the moment τ generated by gravity pedaling down can reach the maximum value, that is, τ=F×R. However, when one leg applies force to the pedal lever arm R of the turntable, the lifting of the other leg does not apply torque to the turntable, unless the pedal is equipped with shoe covers or shoe clips, and even if the leg force is greater than the body weight, as long as the human body sitting on the chair cushion, the maximum force that the rider can step on is only the body weight, unless the human body leans forward from the seat and pulls the arms upwards to pull the arms downwards to increase the downward pressure on the pedals. The movement of “stand-up pedaling” has the opportunity to exert pressure under excess body weight; if it is a reclining or recumbent bicycle, although the foot is stepped forward or pulled back (when there is a shoe cover or a shoe jam), each cycle is additional invalid power consumption of leg lift must be applied from bottom dead center to top dead center.

In view of the shortcomings of the above-mentioned rotatory pedaling prime mover, a prime mover that can provide the most effective work is highly expected by the industry. Therefore, the present invention disclose a reciprocating linear pedaling prime mover. The feature of this linear reciprocating pedaling prime mover is that the reciprocating rotatory motion of the legs is modified into the reciprocating linear flexion and extension of the legs, by which one leg is flexed while the other leg is stretching, the combined force of the legs can be multiplied by the force. After each linear motion stroke is completed, the reverse linear motion stroke is repeated, and the driving direction remains unchanged. At any moment of the full stroke of the reciprocating linear flexion and extension of the legs, both can generate 2 times of the instantaneous power equivalent to the maximum moment point of the circular rotation, that is, the moment when the gravity is stepped down, τ=(F1+F2)×R×sin(90 degrees)=(F1+F2)×R×cos (0 degrees)=(F1+F2)×R≅2×F×R.
