The specific embodiment
Conjunction with figs. is enumerated following preferred embodiment, in order to structure of the present utility model and effect are elaborated.
Please consult Fig. 1 earlier, be the bicycle 10 learning to drive of helping of the utility model first preferred embodiment, bicycle 10 includes a car body 20 and a foot-operated group 40.
Please cooperate and consult Fig. 2, car body 20 has a vehicle frame 22, and the rear and front end of vehicle frame 22 is pivoted with a front-wheel 24 and a trailing wheel 26 and vehicle frame 22 respectively and is installed with a pipe 221 in the position near trailing wheel 26, in order to install a seat cushion 223 that supplies the rider to take.The place ahead of seat pipe 221 is installed with a junction 28, the cross section of connecting portion 28 is square, and connecting portion 28 has on one slotted eye 282 and slotted eye 284 once, as shown in Figure 3, upper and lower slotted eye 282,284 is interconnected, connecting portion 28 is equiped with a screw rod 286 and a fixed block 288 in last slotted eye 282, screw rod 286 passes fixed block 288 and stretches into down in the slotted eye 284.Car body 20 also has a connection piece 30, and attaching parts 30 has a pipe link 32 and a plate 34, and the bottom of pipe link 32 is fixedly arranged on the end face of connecting panel 34, and the top of pipe link 32 is then stretched into down in the slotted eye 284.Pipe link 32 has a screw 322, and pipe link 32 is spirally connected by screw 322 and screw rod 286, and attaching parts 30 can be combined with the connecting portion 28 of car body 22.The bottom surface of connecting panel 34 has a turtledove type chute 342.
Foot-operated group 40 has a gear case 42 and two cranks 44, and an end of each crank 44 is connection gear case 42 respectively, and the other end connects a pedal 46.Gear case 42 has a driven wheel 422, and the end face of gear case 42 has a turtledove type slide rail 424.Gear case 42 embeds in the turtledove type chute 342 of attaching parts 30 by turtledove type slide rail 424, as Fig. 2 and shown in Figure 4, foot-operated group 40 is installed on the vehicle frame 22, and makes the trailing wheel 26 of driven wheel 422 contact car bodies 20.By stepping on two pedals 46, can drive driven wheel 422 by two cranks 44 and rotate, driven wheel 422 will drive trailing wheel 26 synchronously and rotate, and advance in order to order about bicycle 10.
When child begins to learn to drive bicycle, have no idea once to learn to control, action such as balance and pushes pedals, therefore, when utilizing the utility model to learn to drive bicycle, can be earlier pull down from vehicle frame 22, allow child contact to earth, and advance according to the personal habits action with both feet with riding group 40, how study is controlled bicycle 10 and is driven the needed sense of equilibrium when advancing, and also can prevent that both feet from running into pedal 46 and injured.When child association how to control with balancing leg treadmill 10 after, the turtledove type slide rail 424 that to ride group 40 again embeds in the turtledove type chute 342 of attaching parts 30, makes driven wheel 422 contact trailing wheels 26, when pushes pedals 46, driven wheel 422 can drive trailing wheel 26 and rotate, and advances in order to order about bicycle 10.Owing to learned higher the controlling and balance of degree of difficulty before, therefore can very fast association more how to cooperate pushes pedals 46 to advance, in order to shorten the time that study drives bicycle 10, and in pushes pedals 46, as if the strength deficiency of transmission, can utilize the turtledove type slide rail 424 and the relation of turtledove type chute 342 to adjust the position of foot-operated group 40, increase the area of contact of driven wheel 422 and trailing wheel 26, thus, can increase the strength of driven wheel 422 transmission trailing wheels 26.In addition, also can make pipe link 32 in moving up and down in the slotted eye 284 down by screwing or unscrew screw rod 286, foot-operated group 40 also can move up and down along with pipe link 32, can adjust the area of contact of driven wheel 422 and trailing wheel 26 equally.
Thus, the utility model not only can help child to drive bicycle fast, in order to shorten the time that study drives bicycle, and, utilize cooperating of turtledove type slide rail and turtledove type chute, can adjust the strength of transmission according to different riders' needs, to increase the utility model convenience in the use.
See also Fig. 5, the bicycle of learning to drive for helping of being provided of the utility model second preferred embodiment 50, its keystone configuration is identical substantially with last embodiment, precisely because difference is: in the present embodiment, the end face of gear case 62 is installed with a pipe link 622, and pipe link 622 stretches in the following slotted eye of connecting portion 52 and is spirally connected with screw rod 54; Thus,, make pipe link 622, also can adjust the position of foot-operated group 60, in order to the area of contact of adjusting strip driving wheel 624, to reach the purpose of this utility model with trailing wheel 56 in moving up and down in the slotted eye down equally by screwing or unscrew screw rod 54.
