Embodiment Construction

[0057] Hereinafter, bicycles according to embodiments of the present invention will be described in detail with reference to the drawings.

[0058] A side view of the bicycle according to the first embodiment of the present invention is figure 1 And its A-A line sectional view is figure 2 As shown, it is characterized in that when the front ends of the left and right sides of the crank shaft are combined with the crank arms (CA), the center angle difference between the crank arms is removed, and the crank arm (CA) and the frame (F) as an integrated component of the crank shaft A reaction unit (11) is provided between them.

[0059] From the perspective of constituent elements, the bicycle of the embodiment includes: a frame (F), a front wheel (W1) and a rear wheel (W2) are respectively combined at the front end and a rear end; The crank arm (CA), the crank shaft is connected to the lower end of the frame (F) in a rotatable state between the front wheel (W1) and the rear whe...

Abstract

The present invention relates to a bicycle and adopts a mechanism for applying force to a pedal and generating a driving force for riding of a method wherein crank arms are coupled to the right and left front ends of a crankshaft while removing the difference in central angle between the crank arms, and a driving force for riding is generated through normal rotation and reverse rotation of the crank arms within an arbitrary section. Therefore, it is possible to obtain: a bicycle having a desirable structure in which a force is very effectively applied to a pedal without the loss of the force of a rider and a groin region of the rider incurs no pain; and a superior horseback riding type bicycle capable of providing a rider with a feeling close to actually riding a horse. In addition, since it is possible to easily alter the coupling angle of the crank arms, as necessary, into a normal bicycle shape, the horseback riding type bicycle of the present invention is very practical.

Description

technical field [0001] The present invention relates to a bicycle, and more particularly to an ideally configured bicycle in which the rider's forces act on the pedals very efficiently without causing pain in the groin region of the rider. [0002] The present invention also relates to a special bicycle which, thanks to the above-mentioned efficient force mechanism, enables the rider to experience an almost perfect riding sensation. Background technique [0003] Bicycles have a wide range of uses from transportation to sports and leisure tools. [0004] As is well known, the basic working mechanism is that the force of the cyclist acting alternately on the pedals on both sides passes through the crank arm, the crank shaft, the drive rotating body (usually a sprocket, but also in the case of bevel gears (chainless bicycles)) and the transmission member (Usually a chain, but there are cases where gears form a shaft (chainless bicycles)) is converted into the driving force tha...
