Abstract
The utility model relates to a ratchet type lengthened pedal power-saving bicycle. A pedal arm 2 the length of which is 40 to 60 cm is arranged on a centre shaft 9 of a bicycle chain dish 4 to be positioned between the bicycle chain dish and a ratchet wheel 8 fixedly arranged on the centre shaft, and a pedal 1 is arranged on one end of the pedal arm, while the ratchet wheel 8 is arranged on the other end. A back-action elastic member 6 is arranged on the pedal arm 2. Compared with an existing bicycle which is driven by the circular motion of pedal thereof, the bicycle of the utility model can be operated to precede continuously by that feet tread alternately the pedal 1 up and down, and meanwhile because the long-armed pedal can save labor, the speed of bicycle can be raised without the increased power of human body.
Description
Technical field
The utility model design non-motorized vehicles, particularly a kind of improvement design-calculated bicycle that carried out.
Background technology
Bicycle pedals and chain dish constitute lever construction.According to the laborsaving principle of lever, the long more bicycle of riding of foot-operated arm is just laborsaving more.But since foot-operated overhead distance, front-wheel and ride between distance and the restriction of multiple factor such as human body lower limbs range of movement, the general length of existing bicycle pedals arm is about 20cm.If do not change the structural pattern of existing bicycle pedals, want to realize that by the foot-operated arm that extends laborsaving driving bicycle running is difficult to finish.
Summary of the invention
The utility model is changed the physical construction of existing bicycle pedals and the type of drive that rotation scrunches, and a kind of bicycle of the foot-operated arm that extends is provided, and purpose is that it is ridden is more laborsaving.
The length of the foot-operated arm 2 of said bicycle is 40～80cm, and the one end is equipped with rides 1, and the other end is equipped with ratchet 10, and foot-operated arm 2 slidable fit are on the axis 9 of chain dish 4, between chain dish 4 and ratchet 8; Ratchet 8 is fixedly mounted on the axis 9; Also establish resilient elastic component 5 on the foot-operated arm 2.
The utility model is alternately trampled stretcher 1 up and down with bipod, bicycle is turned round continuously to move ahead, rather than existing the foot-operated of bicycle of picture drive to travel as circular movement and since long-armed foot-operated can be laborsaving, the speed of a motor vehicle is improved not strengthening under the situation that human body exerts oneself.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is structure enlarged diagram between foot-operated arm, ratchet and the chain dish.
The specific embodiment
Below specified embodiment by accompanying drawing 1 and accompanying drawing 2.The length of foot-operated arm 2 is 40～80cm, is good with 50cm or greater than 50cm usually.The one end is equipped with ratchet 10, and slidable fit is on the axis 9 of chain dish 4, between chain dish 4 and ratchet 8.Ratchet 8 is fixedly mounted on the axis 9.Also establish resilient elastic component 5 on the foot-operated arm 2, time power elastic component 5 shown in Figure 1 is a tension spring, and an end of spring is fixed on the foot-operated arm 2, and the other end is fixed on the vehicle frame 3.Return power elastic component 5 and also can make the jump ring structure.
When riding, only using foot is trampled stretcher 1 downwards, and chain dish 4 rotations that make foot-operated arm 2 drive axis 9 and be attached thereto by ratchet 10 and ratchet 8 move ahead wheel 7 by chain 6 again.Pine is during pin, returns power elastic component 5 and makes stretcher 1 original place of rebounding, and do not produce propulsive effort when ratchet 8 is with ratchet 10 counter motions simultaneously.Bipod is alternately trampled stretcher 1 up and down, bicycle is turned round continuously move ahead, rather than existing the foot-operated of bicycle of picture drives to travel as circular movement.Since long-armed foot-operated can be laborsaving, the chain dish also can than doing of existing bicycle more greatly, the speed of a motor vehicle is improved not strengthening under the situation that human body exerts oneself.This long-armed riding also can be installed on the tandem bicycle.
Claims (1)
