Description

A kind of pedal drive bicycle

Technical field

The present invention relates to the bicycle field, particularly a kind of through pedal is done work, drive foot pedal apparatus and drive corresponding chain gear apparatus, drive trailing wheel by chain gear apparatus and rotate, realize a kind of pedal drive bicycle that the back-wheel drive front-wheel advances.

Background technology

In the society now that makes rapid progress, bicycle is also constantly changing profile, material, function, unmodified only along with the development of society; Be bicycle basic structure, promptly handle connects front-wheel through front fork, and trailing wheel is fixed through back vent; Marriage chain wheel apparatus connecting crank again, the pedal of stepping on the crank through manpower makes the back-wheel drive front-wheel forward, front fork, back vent and crank etc.; All be installed on the support and fix, also be unable to do without the saddle on support certainly, supply the people easily to sit down; Therefore, bicycle also becomes the walking-replacing tool of people's leisure and environmental protection trip naturally.

It is big that treadmill has a volume, and the characteristics of Heavy Weight are difficult for carrying; Usually in this specific place, fitness room, place; Therefore just place indoor in the majorityly, receive airless puzzlement, and there is the problem of energy dissipation in treadmill; Spend in people's power potential energy on the simple mechanical work the effective utilization when not possessing acting to energy.

Summary of the invention

The objective of the invention is to overcome the deficiency of prior art, provide a kind of human body not only capable of using to run energy drives that acting produces, but also the pedal drive bicycle that can carry out outdoor activity.

Therefore; The present invention includes rack-mount handle and be installed in the front-wheel and the trailing wheel that can pivot on the said support, the after poppet arm that support is provided with slide rail and is used for fixing trailing wheel, the after poppet arm is fixed a rear support bracket; Be provided with the chain wheel set of strap drive function between after poppet arm and the bearing support; Chain wheel set comprises drive wheel, flower wheel and chain, and drive wheel is provided with transmission component, and the end of transmission component is movably arranged on the said slide rail.

Said transmission component comprises crank, drive link and pedal, and an end of said drive link is to be movably installed on the said slide rail, and the other end of said drive link flexibly connects crank.

Drive link is provided with and can comes and goes the pulley that slides along slide rail.

Said pedal is respectively left-hand tread plate and right-hand tread plate; Cooresponding with said left-hand tread plate is Left Drive bar and left slide rail; Said right-hand tread plate is cooresponding to be right drive link and right slide rail, and when said left-hand tread plate was positioned at the oblique upper end position of left slide rail, said right-hand tread plate then was positioned at the oblique lower end position of right slide rail.

It between said slide rail and the support slideway for oblique shape.

Be to be the circular arc slideway between said slide rail and the support.

Beneficial effect of the present invention is the after poppet arm that support is provided with slide rail and is used for fixing said trailing wheel, and said after poppet arm is fixed a rear support bracket, is provided with the chain wheel set of transmission between said after poppet arm and the said bearing support; Said chain wheel set comprises drive wheel, flower wheel and chain, and drive wheel is provided with transmission component, and the end of said transmission component is movably arranged on the said slide rail; Said transmission component comprises crank, drive link and pedal; One end of drive link is to be movably installed on the said slide rail, and the other end of said drive link flexibly connects crank, and drive link is provided with and can comes and goes the pulley that slides along track; Therefore; Alternately sliding significantly of left and right sides pedal and make left and right sides crank drive drive wheel to rotate, utilize the sliding stroke of pedal and this slide rail, realize that finally people's running is moved; Can in treadled cycle, guarantee the steady scanning frequency of bicycle again.

Fig. 1 is a block diagram of the present invention.

Fig. 2 is a support block diagram of the present invention, shows the gap tilt effect of slide rail and support body.

Fig. 3 is the rear drive sprocket scheme drawing.

The specific embodiment

As shown in Figure 1, the present invention includes the handle 1 that is installed on the support 4 and be installed in the front-wheel 2 and trailing wheel 3 that can pivot on the said support 4, the after poppet arm 42 that support 4 is provided with slide rail 41 and is used for fixing trailing wheel 3; After poppet arm 42 is fixed rear support brackets 5, is provided with the chain wheel set 6 of transmission between said after poppet arm 42 and the bearing support 5, and chain wheel set 6 comprises drive wheel 61, flower wheel 62 and chain 63; Drive wheel 61 is provided with transmission component 7; The end of said transmission component 7 is movably arranged on the said slide rail 41, and said transmission component 7 comprises crank 71, drive link 72 and pedal 73, and an end of drive link 72 is to be movably installed on the said slide rail 41; The other end of drive link 72 flexibly connects crank 71; Drive link 72 is provided with and can comes and goes the pulley 43 that slides along slide rail 41, sees through the action of doing work more smoothly when pulley 43 helps people's pushes pedals 73, certainly; Also pulley 43 assistant slidings can be set; That is to say, when the contact surface between drive link 72 and the slide rail 41 has enough slick and sly contact surfaces, just can realize doing to come and go the action of sliding according to slide rail 41.

As shown in Figure 2, be to be oblique shape slideway between said slide rail 41 and the support 4, further, and according to the action of human body road-work, can be being to be the circular arc slideway between said slide rail 41 and the support 4.

Combine shown in Figure 1 like Fig. 3; Said pedal 73 is respectively left-hand tread plate and right-hand tread plate; Cooresponding with said left-hand tread plate is Left Drive bar and left slide rail, and said right-hand tread plate is cooresponding to be right drive link and right slide rail, when said left-hand tread plate is positioned at the oblique upper end position of left slide rail; Said right-hand tread plate then is positioned at the oblique lower end position of right slide rail, and two pedals form the alternating movement of oblique upper and lower end.

It should be noted that said rear support bracket 5 is installed in formation oblique angle effect on the after poppet arm 42, makes crank 71 be set at the vertex of rear support bracket 5; When human body stands on the pedal 73, will be easily to exert pressure to crank 71 gravity is basipetal, promptly most gravity is born by crank 71; Cooperate rear support bracket 5 drive wheel 61 postposition simultaneously; Make the people when velocipede, the action span in the time of can using common run, it is excessive and cause the problem that pulls a muscle to solve span.

Therefore, alternately sliding significantly of left and right sides pedal and make left and right sides crank drive drive wheel 61 to rotate utilized the sliding stroke of pedal 73 and this slide rail 41, finally realizes people's running action, can in treadled cycle, guarantee the steady scanning frequency of bicycle again.
