Abstract
The invention discloses a tandem bicycle adopting double-pedals to drive one chain. The tandem bicycle is composed of the double-pedals, a front seat, a rear frame, a rear seat, a rear handlebar and a single bicycle body, wherein people at the front seat and the rear seat simultaneously tread the double-pedals to drive the chain to move forwards. Each double-pedal is formed by mounting a front seat pedal and a rear seat pedal which are independent of each other on a supporting rod, and the rear seat pedal is one to ten times thicker than the front seat pedal. A bearing or a ball in each rear seat pedal is filled with high-viscosity damping grease, so that the rear seat pedal needs to be treaded by external force to change the angle of the pedal face. The distance between the pedal face of each rear seat pedal and the corresponding supporting rod is one to nineteen times the distance between the other pedal face to the supporting rod. The included angle of the center line of an extending part for fixing the front seat at the upper portion of a seat rod of the front seat and the center line of the seat rod is smaller than 90 degrees. The rear seat is fixed to the rear frame. The front and rear positions of the rear seat can be adjusted on the rear frame. A row of mounting holes can be formed in the front and rear positions of the rear frame.
Description
Technical field
The present invention relates to a kind of tandem bicycle, it is characterized in that using Double-person pedal to drive a chain to advance.
Background technology
At present, known seat tandem bicycle front and back is all to be driven by chain so that the length of tandem bicycle and the single bicycle of weight ratio increase a lot, are unfavorable for train and aircraft on strap.
Summary of the invention
In order to overcome existing seat tandem bicycle front and back, because of chain, the long car weight of body is unfavorable for train and the deficiency of aircraft on strap, the present invention provides a kind of tandem bicycle using Double-person pedal to drive a chain, this tandem bicycle uses Double-person pedal to drive a chain to advance, it is no longer necessary to chain drive, so that the length of bicycle and weight will not substantially increase, facilitate train and aircraft on bicycle strap.
The people of the technical scheme is that front stall of the present invention and back seat steps on piece chain advance of Double-person pedal driving by stepping on simultaneously.Double-person pedal is to be contained in a pole by the pedal of front stall pedal and pillion steps the two independence above to be formed.Pillion steps thick 1 to 10 times than front stall pedal.Pour into high viscosity damping grease in bearing in pillion steps or ball, make pillion steps need external force to go to step on the angle that could change pedal tread.The pedal tread of the pillion steps distance away from pole is equal to 1 to 19 times of its another pedal tread distance away from pole.The centrage of the extension of the front stall angle with the centrage of seatpost is fixed less than 90 degree in the seatpost top of front stall.Rear handle is fixed on after-frame.Back seat is fixed on after-frame.Before and after back seat, position can adjust on after-frame.Row's installing hole can be had on position, it is simple to adjust position before and after back seat before and after on after-frame.Double-person pedal is arranged on single bicycle body, after-frame, back seat and rear handle or be combined into an entirety with former single bicycle body by welding or by screw installation, makes single bicycle become tandem bicycle.
The invention has the beneficial effects as follows, use Double-person pedal can need not chain device and just double can simultaneously drive a chain advance, so that the length of bicycle and weight will not substantially increase, facilitate train and aircraft on bicycle strap.

Detailed description of the invention
In FIG, Double-person pedal (1) is to be simultaneously driven by the people on front stall (2) and back seat (5).Rear handle (4) is fixed on after-frame (3).Back seat (5) is fixed on after-frame (3).Before and after back seat (5), position can be in the upper adjustment of after-frame (3).Row's installing hole can be had on position, it is simple to adjust position before and after back seat before and after on after-frame.After-frame (3) with former single bicycle body or weld together and be combined into an entirety, or can be installed by screw and be combined into an entirety.
In fig. 2, Double-person pedal is to be contained in a pole (8) by the pedal of front stall pedal (6) and pillion steps (7) the two independence above to be formed.Pillion steps (7) thick 1 to 10 times of front stall pedal (6) of ratio, it is to avoid when riding, the foot of two people touches together.Pour into high viscosity damping grease in bearing in pillion steps (7) or ball, make pillion steps (7) need external force to go to step on the angle that could change pedal tread.The pedal tread of pillion steps (7) distance away from pole (8) is equal to 1 to 19 times of its another pedal tread distance away from pole (8).
In figure 3, the angle of centrage of centrage and seatpost of extension of front stall is fixed less than 90 degree in the seatpost top of front stall, it is simple to front stall moves forward 2 to 8 centimetres, the center of gravity of bicycle so can be made toward reach, can leave installing space to rear handle again.
