Specific embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
Embodiment one、As shown in Figure 1，A kind of bicycle,Including vehicle frame 1、Front vehicle wheel 2、Rear wheel 3、Steering yoke 5、Saddle 6 and brake system 26，Vehicle frame 1 both sides are provided with foot-driven lever 4，One end of foot-driven lever 4 is provided with the axis hole being connect with vehicle frame axle and is connect with vehicle frame 1 axle by axle 7，The other end of foot-driven lever 4 is provided with the arc-shaped rack 9 of point centered on the axle center of axle 7，It is provided with pedal 8 between the two ends of foot-driven lever 4，The both sides of rear wheel 3 are respectively arranged with the ratchet-gear wheel 10 being meshed with arc-shaped rack 9，Foot-driven lever 4 is provided with resetting means，Resetting means is the pulley 18 being arranged on vehicle frame 1 and hangs over the elastic threads 19 on pulley 18，Arrange fluted on pulley 18，Elastic threads 19 hang in groove，It is provided with the baffle plate 20 preventing elastic threads 19 from skidding off outside pulley 18，Elastic threads 19 one end is fixed therein on the arc-shaped rack 9 an of foot-driven lever 4 one end，Elastic threads 19 other end is fixed on the arc-shaped rack 9 of another foot-driven lever 4 one end，Pedal 8 is provided with foot-operated rod set 12，Foot-operated rod set 12 is enclosed within foot-driven lever 4 and can move forward and backward，Foot-operated rod set 12 is provided with lock screw，It is provided with multiple holes do not punched inside foot-driven lever 4，Lock screw is worked in coordination with hole，Ratchet-gear wheel 10 both sides are provided with the back-up ring 13 preventing arc-shaped rack 9 from swinging，Service brake arrangement is separately provided with vehicle frame 1，Service brake arrangement is by service brake elastic threads 15、Service brake support 17、Brake pedal 22、Brake shoes 21 and buckle 16 form，Brake pedal 22 is fixedly installed on service brake support 17，Service brake elastic threads 15 one end and vehicle frame 1 are connected，The other end is connected with service brake support 17，Buckle 16 is arranged on service brake support 17 both sides and can be slided on vehicle frame 1 with vehicle frame 1 cooperation，Brake shoes 21 is arranged on the lower end of service brake support 17，When treadmill people tramples one of pedal 8 downwards，The arc-shaped rack 9 of one end also glides simultaneously，Ratchet-gear wheel 10 and rear wheel 3 is driven to rotate，When treadmill people tramples downwards another piece of pedal 8，The arc-shaped rack 9 of the other end also glides simultaneously，Ratchet-gear wheel 10 and rear wheel 3 is driven to rotate，That foot originally lifts，Pedal 8 is also and then upspring in the presence of elastic threads 19，That foot originally continues to trample，So back and forth movement，Car is driven to advance，Treadmill people stands or seat and all can be trampled，If seat and is trampled or trample people's body weight and more foot-operated rod set 12 can be moved backward，So can easily trample，If stand trampling，Especially fat person can be foot-operated rod set 12 toward reach，Road speed so can be accelerated，And the lock screw in foot-operated rod set 12 can be designed to the screw with spring or pin，Band Spring screwses or pin one end add a handle，Other end design is in round end or tip，The foot-driven lever set 12 as long as a handle can slide，The local screw or the pin meeting appliance for releasing single that slide into hole are tight，So easily adjust road speed，If road speed is too fast and chance emergency needs to brake，Even if traditional bicycle brake 26 once checks wheel 2 and wheel 3，Wheel 2 and wheel 3 also can continue to slide because of inertia，Service brake now can be used，Stepping on brake pedal 22 brake shoes 21 can directly contact ground，Producing friction with ground increases resistance，Bicycle is made quickly to stop，Can reduce or mitigation accident.
Embodiment two is as shown in figure 1, become tricycle bicycle designs（Not shown on the FIG.）Other settings are ibid, because tricycle will not be outwelled, so not only ordinary people can use, and be also available for single lower limb people with disability and use, need only be dead on pulley or locking elastic threads when single lower limb people with disability uses, so that elastic threads will not be slidably reciprocated on pulley, such people with disability's list foot is stepped on another pedal during pedal and will not be upspring, when its single foot lifts, pedal also can and then be upspring in the presence of elastic threads, as long as single foot is trampled also can drive to advance.
Embodiment three, as shown in Figure 2, the setting of bicycle is ibid, the arc-shaped rack 9 being arranged on foot-driven lever one end is substituted with bicycle chain, arc-shaped rack 9 is made into arc groove, setting chain 25 in groove, chain 25 two ends are fixed with the two ends of arc groove respectively by chain lock screw 23, chain 25 is cooperated with ratchet-gear wheel 10, the both sides of ratchet-gear wheel 10 need not arrange ring washer 13 again, the both sides of arc groove can be enclosed within the both sides of ratchet-gear wheel 10, make its will not transverse shifting, the arc-shaped rack 9 of foot-driven lever 4 and one end can one or split setting.
