Abstract

The bicycle for health and recreation is a health and recreation instrument, which takes traditional bicycle as prototypes, and can ride freely out of the door after refitted and prepared. The bicycle is driven by feet pedaling downwards at the same time, which can make the rider moving in waves and non-uniformly by using crank-Bar Linkage driving the back of eccentric Wheel. The rider will feels exciting and enjoying as ride a running pony because of the body rising, falling, dashing and lagging from time to time, and by this way, the rider can get the purpose of amusements and fitness. The bicycle is highly full of novelty and innovation, reliability, safety and suitable to people of all ages.

Description

Recreation bicycle

Affiliated technical field

The utility model is a kind of main for teenager's amusement, can take exercises, improve the exerciser of balanced capacity and alerting ability again in amusement.

Background technology

Health and fitness facilities in the market mostly is fixed, and is dull relatively.General bicycle for teenager's amusement mostly is parallel and travels, and lacks recreational and pungency.

Summary of the invention and technique effect

Comprehensive in the market bicycle and some deficiency of health and fitness facilities, the technical solution of the utility model be traditional bicycle repacking is mixed with can be in outdoor freedom, travel safely and take exercise; Can do significantly in motion, rhythmical undulation; The recreation bicycle of scalable dynamics size again on diligent.

The technical measures that the utility model adopts are that (1) 1. is diligent mode and the saddle type soft cushion of mating horses (as Fig. 3, Fig. 5 shows) with both feet with pedaling the parallel double pedal at present.(2) with the parallel double pedal 1. link step on handle 2., preceding crank 4., connecting rod 6., 8. rear crank be type of drive, make after crank shaft 7. (that is be coaxial composite eccentric axle 7.) rotate (as shown in Figure 3).(3) trailing wheel is an eccentric wheel.It is with bicycle rim and corresponding different length No. 13 bike spokes voluntarily, with cross-like or radiation-like, by eccentric size requirements, is assembled into composite eccentric with the bicycle pattern wheel of connecting shaft and takes turns 9. (as Fig. 3, shown in Figure 4).

Technique effect of the present utility model is that when car moved ahead, the person of riding can along with the rhythm of pedaling under the both feet, can experience strong rhythmical advancing wave upon wave just as riding over the little horse back of running quickly.Moreover, not at the uniform velocity move ahead in the time of also can making the person of riding and preshoot, time then stagnate, very stimulate joyful (with 26 o'clock bicycles was example, pedaled once under the person's of riding both feet, and back eccentric wheel rotates a week, and its difference of height is 15 centimetres).

When both feet are pedaled down on riding over shape of a saddle cushion, understand the impression that pin is stepped on stirrup when riding.Because of it is step hard, require great effort than traditional bicycle when pedaling down, so can temper both legs muscle.As the torque adjusting hole on the crank before will changing both feet firmly dynamics can being adjusted 5..

Brake before and after being furnished with on the car, turns to flexibly driving safety, but than driving standard bicycle higher difficulty is arranged, and the raising person's of riding alerting ability and balanced capacity is beneficial to.

Drive the utility model and ride traditional bicycle or operation fitness equipment, on recreational, pungency, diverse impression is arranged.Ground such as it can be on the square, court, road drive, not only can amusement but also can body-building.

Wherein: pedal * 2 1., step on handle * 2 2., shared axis 3., preceding crank 4., the torque adjusting hole 5., connecting rod 6., 7. (7. coaxial with the composite eccentric axle), rear crank are 8., 9. composite eccentric wheel (7. make up consubstantiality with the composite eccentric axle) for after crank shaft.

Fig. 3 is architectural feature and operation logic figure

When 1. the parallel double pedal was in the extreme higher position, 7. the composite eccentric axle was in extreme lower position (as shown in Figure 3).When both feet simultaneously to the parallel double pedal when 1. diligent, 1. and step on handle and 2. move downward simultaneously pedal, with step on the 2. same axis of handle preceding crank 3. and 4. travel forward simultaneously, 6. the linkage connecting rod travels forward, 8. the connecting rod rear crank that 6. links again makes circular movement, and after crank shaft is 7. in company with rotating (annotate: after crank shaft is 7. 7. coaxial with the composite eccentric axle, and 9. is combined into one with the composite eccentric wheel), so 9. the composite eccentric wheel rotates the 7. lifting of composite eccentric axle.

When 1. the parallel double pedal moved to extreme lower position, both feet stopped hard to pedal, and at this moment, 7. the composite eccentric axle has been lifted to the extreme higher position.The effect that relies on inertia that car moves ahead and car center of gravity to glide, 9. the composite eccentric wheel is rotated further, the linkage rear crank 8. with connecting rod 6., preceding crank 4., step on handle 2., 1. pedal be withdrawn into Fig. 3 position.So go round and begin again, 7. the composite eccentric axle of car trailing wheel constantly moves ahead as wave.

Specific embodiments

The utility model can be ordered partially self car parts and antifriction-bearing box is reequiped preparation.Its running part and trailing wheel part can be implemented by technical measures of the present utility model.All size, various style bicycle all can be by its different sizes preparations.

This place has produced sample car and can supply to visit, test, and it is for reference to have detailed physical construction drawing.

Easy to make, the deft design of the utility model, Bicycle Plant, accessory factory, fitness equipment factory, hardware factory all can be under technical personnel instructs processing and fabricating.

At present in the society one child's bicycle heat, keep-fit fever are arranged, be expected the utility model and can satisfy needs in the society.

Claims (2)

1, a kind of recreation bicycle, constitute by vehicle frame, front-wheel, trailing wheel, seat saddle, handlebar, transmission combination etc., it is characterized in that the vehicle frame middle and lower part establishes the parallel double pedal and 1. step on handle 2., before connecting crank 4., connecting rod 6., 8. rear crank constitute the combination of transmission, the composite eccentric wheel is established in the vehicle frame rear portion 9..
