The present invention relates to a bicycle capable of driving with a pinwheel driving force using hands, feet and wind. In a general bicycle, the power of the bridge is transmitted by the pedal when the wind or the slope is climbed, and it is very difficult to drive, especially during long distances, so the fitness speed drops so that the driving speed is not suitable.

The present invention was devised to eliminate such drawbacks, and as the acceleration power of the bicycle was applied, more wind power was used, and the driving force due to the rotation of the propeller, which is the principle of the airplane, was used. Of course, the improved handle handle can be obtained by driving up and down reciprocating as a bicycle using a combination of human and natural forces at the same time will be described in detail below the present invention.

Gearbox is installed on the existing bicycle handle to build the horizontal axis bevel gear, driving first gear and driving third gear on the drive transmission 1 horizontal axis, and inserts ball bearings outside the gearbox to the one-side chain gear on the right side and wind power on the left side. The brake shaft is installed and the pinwheel shaft of the longitudinal bevel gear meshed with the transverse bevel gear is fixed with a ball bearing, and both sides of the gear box are combined with a second handle on the second transmission axis. The second gear and the fourth driving gear is constructed as a driving bicycle which can be driven by using the limbs and wind power, which is composed of a handle safety wind key attached to an inlet and a gearbox support, and will be described with reference to the accompanying drawings.

When driving for the first time, hold the primary steering wheel and drive up and down by holding the secondary steering wheel with both hands after gaining the inertia force.When lifting the secondary steering wheel 17 as shown in Figs. 1 and 2, The driving second gear 10 and the fourth driving gear 12 do not transmit force by the spot unidirectional gears in the driving fourth gear 12 attached to the driving transmission second horizontal shaft 13. In pressing down (17), the drive fourth gear (12) connected to the drive transmission second transverse shaft (13) when the secondary handle (17) is pushed down so as not to press the wind brake prevention spring (33). The drive transmission second horizontal axis 13 is rotated by the spot one-way gear inside, and the driving transmission second horizontal axis 13 is engaged with the driving third gear 11 so that a force is transmitted to the drive transmission first horizontal axis 8 and the one-sided chain gear 30, thereby cycling the bicycle. The front wheel is to play a role.

The transverse bevel gear 7 and the longitudinal bevel gear 6 mesh with each other as the drive transmission first transverse shaft 18 is rotated, where the drive first gear 9 which is engaged with the drive second gear 10 is rotated more. As the chain is rotated, the one-way gear 30 attached to the end of the first transmission shaft 18 is driven forward by the gear 20 of the front wheel 21 as the chain 19.

And because the pinwheel built on the longitudinal bevel gear (6) is rotated more than the air volume by operating the secondary handle 17 up and down, the proscilla acts to push the air volume back like the principle of an airplane.

As shown in FIGS. 3 and 4, the handle safety key 32 to be attached together with the gearbox support 24 at the lower portion of the gearbox 14 is formed by the indentation of uneven parts such as stones on the road surface. Do not allow the handle to turn easily.

Then, the braking device 25 by pressing the secondary handle 17 in contact with the wind braking prevention spring 33 while driving, the wind braking projection 26 provided on the left side of the secondary handle 17 ascends to the top (27) While lifting the brake, the braking device attached to the left end of the first transverse side 8 of the drive transmission is wrapped with a braking band to brake the wind.

In addition, as shown in FIG. 2, the bicycle itself may be braked by attaching an existing braking device to a primary handle or a secondary handle at a convenient place.

In the driving bicycle using the limbs and the wind of the present invention, when braking and then driving again, as described above, the first handle is operated by holding the first handle, stepping on the pedal as a foot, and inertia reciprocating the second handle up and down. This is because if the secondary handle is reciprocated forcibly from the beginning after braking, damage to the gear such as a spot bearing in the gearbox is caused.

According to the experiments of the present inventors, the force for pushing the pedal with one foot is about 40 (㎏), and the force for pressing with both hands is about 30 (㎏). It has many effects. For example, the gear ratio of the driving gear (spot bearing) unidirectional gear, the driving gear 2, the gear 3 and the gear 4 is made low so that it is possible for people with inconvenient legs or those with body length to use it alone. The present invention, such as being able to be driven, is not limited thereto, and may be modified.
