Abstract
The utility model relates to a bicycle propelled by the disabled persons. The utility model is characterized in that the both sides of the bicycle are separately provided with a transmission mechanism of the chainwheel and the chain and a lever-typed hand car mechanism which is composed of a curved rocking rod, a transmission supporting rod, a supporting rod of the chainwheel and a supporting rod of the curved vehicle frame; the curved top of the curved rocking rod is hinged with the side face of a chair and the lower end of the curved rocking rod is hinged with one end of the transmission supporting rod; the other end of the transmission supporting rod is hinged on the position near the rear end of the middle part of the supporting rod of the chainwheel; the back end of the supporting rod of the chainwheel is hinged on the chainwheel and the front end of the supporting rod of the chainwheel is hinged with the supporting rod of the curved vehicle frame; the other end of the supporting rod of the curved vehicle frame is hinged on the front wheel frame of the bicycle frame. Having the advantages of simple structure, labor saving and sanitation, the utility model is suitable for the disabled persons in the leg.
Description
A kind of bicycle that supplies the shank disable person to take.
Existing wounded or disabled bicycle, a kind of is to travel with the direct rocking-turn sprocket wheel of hands, relatively heavier, dumb, easily overturns, and take very big strength Herba Plantaginis is advanced.Another kind is directly to push away or travel with wheel push boat arranged side by side with hands, and its defective is fine two hands ashes out the time, and rainy days two hands mud is very unhygienic.
The purpose of this utility model provides the wounded or disabled bicycle of a kind of little power, laborsaving when accomplishing to travel, health.This utility model purpose is achieved in that all pacifies the sprocket chain strip transmission mechanism respectively in the both sides of car and by curved rocking bar, transmission pole, sprocket wheel pole, the lever larry mechanism that curved vehicle frame pole constitutes, the bent crown hinge of curved rocking bar is connected on the seat side, lower end and transmission pole one end are hinged, the transmission pole other end is hinged on sprocket wheel pole middle part near on the back-end location, sprocket wheel props up rod rear end and is hinged on the sprocket wheel, front end and bent type vehicle frame pole one end are hinged, the curved vehicle frame pole other end is hinged on the car pot frame front wheel carrier, a left side, the brake of right braking mechanism is being separately fixed at a left side, on the right curved rocking bar.
When spurring curved rocking bar, curved rocking bar is a rotating fulcrum with the pin joint on the seat backward, and up move its lower end, hauls the up motion forward of sprocket wheel rear by transmission pole and sprocket wheel pole.When promoting curved rocking bar forward, its lower end moves down,
Pushing away the down motion backward of sprocket wheel the place ahead by transmission pole and sprocket wheel pole.One of curved rocking bar draws one to push away, and whole sprocket wheel is revolved forward turn around, and pushes away curved rocking bar if ceaselessly draw, and then sprocket wheel ceaselessly rotates, and drives trailing wheel by chain and flywheel and moves forward.If shake left and right curved rocking bar simultaneously, then full car travels forward.
If clutch the curved rocking bar and the brake handle on the left side, only shake the curved rocking bar on the right, then full car is toward turning left.Otherwise full car is then toward turning right.
Compared with the prior art, the light disabled person's labor intensity of this utility model, the characteristics of simple in structure, laborsaving, health are fit to the shank disable person and use.
