Problems solved by technology

This method of riding a bicycle must first force the legs and feet forward and then step down. People are relatively tired when riding, and the effect cannot be well exerted. Although the patent number is "2012201148089" and the patent number is "2012100804348" A kind of pedal bicycle has corrected the driving mode, because the driving force of the corrected driving mode is greater than that of the traditional driving mode, and it is necessary to install a speed change device to convert the excess driving force into the driving speed, which increases the In addition, the fulcrum of the pedal rod is set in the middle part, and the elastic rope to reset the pedal rod must be installed between the fulcrum and the pedal, so that when designing a compact bicycle, the elastic rope The installation will affect the treadmill, especially when getting on and off the bike, it is easy to touch the elastic rope

Embodiment 1

[0015] Embodiment one, as figure 1 As shown, a bicycle includes a vehicle frame 1, a front wheel 2, a rear wheel 3, a steering rod 5, a saddle 6 and a braking system 26, and the two sides of the vehicle frame 1 are provided with a pedal rod 4, and one end of the pedal rod 4 A shaft hole connected with the frame is provided and is connected with the frame 1 through the shaft 7. The other end of the pedal rod 4 is provided with an arc-shaped rack 9 centered on the axis of the shaft 7. The pedal rod 4 Pedals 8 are arranged between the two ends of the rear wheel 3, and ratchet gears 10 meshed with the arc rack 9 are respectively arranged on both sides of the rear wheel 3. The pedal rod 4 is provided with a reset device, and the reset device is arranged on the vehicle frame The pulley 18 on 1 and the elastic rope 19 hanging on the pulley 18, the pulley 18 is provided with a groove, the elastic rope 19 is hung in the groove, the outer side of the pulley 18 is provided with a baffle ...

Embodiment 2

[0016] Embodiment two, such as figure 1 As shown, the bicycle is designed as a tricycle (not shown in the picture), and other settings are the same as above, because the tricycle will not fall down, so that not only ordinary people can use it, but also can be used by one-legged disabled people. Tie or lock the elastic rope on the pulley so that the elastic rope will not slide back and forth on the pulley, so that the other pedal will not spring up when the disabled person steps on the pedal with one foot. The pedal will also bounce under the action of the elastic rope, and the car can be driven forward as long as one foot is stepped on.

Embodiment 3

[0017] Embodiment three, as figure 2 Shown, the setting of bicycle is the same as above, the curved tooth bar 9 that is arranged on one end of pedal rod replaces with bicycle chain, makes curved tooth bar 9 into arc groove, and chain 25 is set in the groove, and chain 25 two ends pass through The chain locking screws 23 are respectively fixed to the two ends of the arc groove, the chain 25 cooperates with the ratchet gear 10, the both sides of the ratchet gear 10 need not be provided with the retaining ring 13, and the both sides of the arc groove can be set on the ratchet gear 10 The both sides of it, so that it can not move laterally, the arc rack 9 of pedal rod 4 and one end can be integrated or split.

Environmental protection, "driving less, cycling more" is gradually being recognized by people and encouraged by the government. It is this era background and the role of historical tradition that bicycles have regained their former status in people's minds, but the tradition The bicycle is rotated 360 degrees by the pedal, and the wheel is driven by the sprocket and the chain to drive forward. This method of riding a bicycle must first force the legs and feet forward and then step down. People are relatively tired when riding, and the effect cannot be well exerted. Although the patent number is "201220114808...
