Description

Seat is by recumbency riding type high-speed bicycle

The utility model relates to a kind of bicycle.

The process of riding of existing bicycle is that the bicyclist is sitting on no backrest and the narrow again seat, both hands are held the handlebar on the front-wheel, and left and right sides pin is stepped on foot-operated on the dynamic crankshaft handle respectively downwards and allowed chain crop rotation circumference rotate and drive flywheel and trailing wheel by chain and rotate bicycle is advanced.It is foot-operated that this process of riding can not firmly be stepped on cyclist left and right sides pin simultaneously, the seat is narrow not to have backrest again, not only allow the cyclist feel the discomfort of waist, stern, hip, leg and hand when riding, but also the vehicle body (being wheel base) that influences bicycle can not shorten and the bicycle speed of advance can not better be improved.

Steamboat footpath and variable speed bicycle that bicycle manufacturer provides to market, for shortening vehicle body and improving the speed of a motor vehicle and played certain effect, but whole process and the mode of taking of riding fails to change, people's sticky feeling and better shorten the wheel base of bicycle and improve the speed of a motor vehicle when also just failing to solve by bike.

The purpose of this utility model is exactly can the whole process of riding of change lean on recumbency riding type high-speed bicycle with the seat of taking mode for people provide a kind of, people's discomfort sensation when it can reduce by bike effectively better shortens the bicycle wheels distance and improves the speed of a motor vehicle.

The purpose of this utility model be achieved in that the seat that the back of the body arranged be installed in the trailing wheel top of bicycle or two trailing wheels with hind axle and vehicle frame on or on the vehicle frame between the front and back wheel, the plate of pedaling that has antifriction-bearing box is installed on the preceding pipe of bicycle or front wheel spindle is rotated central siphon, left and right sides step tread plate is being pedaled on the plate rotation central siphon with pedaling plate holder plate and screw retention, the shackle rod of an activity and one respectively are installed on the step tread plate of the left and right sides to be connected on the crankshaft handle, installing on sprocket wheel or the vehicle frame on the preceding pipe of bicycle or passing through the drive sprocket bracing frame on the front wheel spindle drive sprocket is installed at bicycle, connect the multistage flywheel on the trailing wheel or connect the little driven sprocket at cycle frame middle part by chain by chain initiatively, and by with same driven chain wheel shaft of little driven sprocket on big driven sprocket on driven chain be connected multistage flywheel on trailing wheel or the hind axle.When the people rides, the cyclist lies and is sitting on the backed seat, left and right sides pin steps down on the step tread plate of the left and right sides respectively and firmly steps on step tread plate simultaneously, step on step tread plate downwards with the half sole of pin on one side, make the shackle rod that is connected on the step tread plate pull down the dynamic crankshaft handle, another side is stepped on step tread plate downwards with the back palm of pin, make the shackle rod on the step tread plate upwards push crankshaft handle, the crankshaft handle of the right and left is stepped on step tread plate the cyclist, and the rotation of whole chain crop rotation circumference is rotated and driven in the drop-down effect in top down on the shackle rod.Left and right sides pin cooperates firmly steps on step tread plate simultaneously, makes the whole process of riding become easily laborsaving, and this just can not realize at standard bicycle.Rider's power passes to little driven sprocket by the chain on the drive sprocket, pass on the multi-change speed flywheel on the hind axle by the chain on the big driven sprocket again, by several grades speed change like this, thereby guaranteed that bicycle can better improve the speed of a motor vehicle under people's application force.Moreover because the cyclist lies to be sitting on the backed seat, left and right sides pin cooperates firmly steps on step tread plate simultaneously downwards, on push up the drop-down crankshaft handle that makes, sprocket rotation, thus guaranteed that whole process and the mode of taking of riding obtains change.

The utility model is because substitute the narrow seat of standard bicycle with backed seat, substitute the foot-operated of standard bicycle with step tread plate, can lie when riding is sitting on the seat, and step tread plate is firmly stepped in pin cooperation in the left and right sides simultaneously advances bicycle, so comfortable especially and easily laborsaving; Simultaneously owing to having increased driven sprocket, so the speed that bicycle advances can better be improved; In addition because this bicycle can produce three-wheel and quadricycle, so realize security and stability requirement by bike easily.
