Abstract

The utility model relates to a pedal rocking bicycle, which is characterized in that a drive arm 22 is driven by handlebars 32 held by hands of people to swing so as to cause a small flying chainwheel 19 to rotate under the action of a small drive arm 10 and a drive rod 20, and then the bicycle is driven to run. Furthermore, the bicycle is also driven by pedals 18 with traditional pedal modes, and thereby, the utility model can be used as a vehicle and for physical exercises.

Description

Foot-operated rocking bicycle

The utility model relates to foot-operated rocking bicycle technical field.

At present the shortcoming that exists of the bicycle that uses is: type of drive is single, and rider's waist makes the lumbar spine unbalance stress to front curve, and health can not get having a rest and regulating, each joint of arm pressurized all the time by bike time the, and the damage easily that is hit.

The purpose of this utility model is: designs a kind of foot-operated rocking bicycle, bicycle both can have been ridden advance, and again can be by Rocking cycle advancing the comfort when making the more reasonable application of force of rider and having increased by bike.

The utility model is achieved in that there is front-wheel 27 vehicle frame 11 front portions; There is trailing wheel 28 at its rear portion; Seat 12 is arranged on the vehicle frame 11; It is characterized in that: be fixed with rocking arm 1 on the front fork central shaft 24 of front fork 29; The other end of rocking arm 1 is connected with rocker-arm link 2 by axle I 30; The other end of rocker-arm link 2 is connected with hinged segments 4; Hinged segments 4 is connected with small rocker 5 by axle II 31; Small rocker 5 other ends are fixed on the handlebar axis 8; Axle II 31 and handlebar swinging axle 25 are on same axis; Handlebar sleeve 9 connects handlebar axis 8; Handlebar sleeve 9 is fixed on to wave by handlebar swinging axle 25 and supports on 26; Waving support 26 is fixed on the vehicle frame 11; Actuating arm 22 connects handlebar sleeve 9; Steel wire gate 7 one ends connect the long pawl 3 in location; Handlebar 32 connects handlebar axis 8; Steel wire gate 7 other ends are fixed on the handlebar 32; Actuating arm 22 is connected with drive rod 20 by axle III 33; The other end of drive rod 20 is connected with little actuating arm 10 by swinging shaft 34; Connecting extension spring I 21 and extension spring II 23 between actuating arm 22 and the drive rod 20; The little sprocket wheel 19 that flies is arranged on the little actuating arm 10; The little sprocket wheel III 17 that flies is on pedal 18 axles; The little sprocket wheel II 16 that flies is fixed on the vehicle frame 11 by axle; The little sprocket wheel I 15 that flies is coaxial with hinge wheel 14; Chain I 35 and the little sprocket wheel 19 that flies; The little sprocket wheel I 15 that flies; Little sprocket wheel II 16 and little 17 engagements of sprocket wheel III, the minor sprocket that chain II 6 connects on hinge wheel 14 and the trailing wheel 28 of flying of flying.

The utility model has the advantages that: reasonable in design, novel, rider's application of force is reasonable and increased comfort, is tempering health again by bike in the vehicle.

Below in conjunction with accompanying drawing, the utility model is described further with embodiment:

Fig. 1 front view, the view of Fig. 2 for making progress, the view of Fig. 3 for making progress at Figure 1B at Figure 1A.

In the accompanying drawing: 1. rocking arm, 2. rocker-arm link, the 3. long pawl in location, 4. articulating joint, 5. small rocker, 6. chain II, 7. steel wire gate, 8. handlebar axis, 9. handlebar sleeve, 10. little actuating arm, 11. vehicle frames, 12. seats, 13. the car after-frame, 14. hinge wheels, 15. fly the sprocket wheel I for a short time, 16. fly the sprocket wheel II for a short time, 17. fly the sprocket wheel III for a short time, 18. pedals, 19. fly sprocket wheel for a short time, 20. drive spindles, 21. extension spring I, 22. actuating arm, 23. extension spring II, 24 front fork center shafts, 25. the handlebar oscillating axle, 26, wave support, 27. front-wheels, 28. trailing wheel, 29. front forks, 30. I, 31. the axle II, 32. handlebars, 33. III, 34. wave axle, 35. chain I.

When this bicycle pedals drives, earlier the long pawl 3 in location being stuck in to locate on the vehicle frame 11 by steel wire gate 7 makes the handlebar 32 can not swing, hold handlebar 32 and grasp direction, foot-operated pedal 18 makes and flies 17 rotations of sprocket wheel III for a short time, chain I 35 drives this moment fly sprocket wheel I 15 for a short time and hinge wheel 14 rotates, and bicycle moves ahead under chain II 6 drives, and does not mesh owing to fly sprocket wheel 19 reverse ratchets for a short time, therefore its axle does not rotate, and flies sprocket wheel II 16 for a short time and plays 35 effects of tensioner chain I; When this bicycle waves driving, the long pawl 3 in location is mentioned from vehicle frame 11, but this moment the rider just both hands pull back handlebar 32 and swing backward, make handlebar sleeve 9, handlebar axis 8 and actuating arm 22 are swung forward around handlebar oscillating axle 25, actuating arm 22 is swung forward through drive spindle 20 drive actuating arms 10 and is swayed, the at this moment for a short time sprocket wheel 19 that flies also rotates, for a short time fly sprocket wheel I 15 and hinge wheel 14 rotations through 35 drives of chain I, bicycle moves ahead under 6 effects of chain II, when actuating arm 10 arrives preceding dead point, extension spring II 23 is tightened up, the moment that drive spindle 20 produces drives actuating arm 10 smoothly by preceding dead point, go-cart is the same 32 its principle of work forward with hand subsequently, and bicycle just can advance continuously; When turning of bicycle, it is all capable of free rotation no matter to ride or wave the driving bicycle, if left-handed turning to, handlebar 32 left-handed turning certain angles, the also same angle of phase inversion of small rocker 5 thereupon, small rocker 5 drives rocking arms 1 by rocker-arm link 2 and rotates equal angular too, because rocking arm 1 is formed one with front fork 29, therefore front-wheel 27 also rotates same angle, otherwise in like manner; Because the axle II 31 on the small rocker 5 and handlebar oscillating axle 25 be on same axial line, so can not cause that front-wheel 27 swings during handlebar 32 swings.
