Description

Children's tricycle driven by rocking chair

The utility model relates to a kind of perambulator, particularly a kind of rolling chair driving type perambulator.

Traditional perambulator is by foot-operated transmission.But, generally can't ride with foot-operated for the child below three years old; And concerning making big slightly children year, also may feel dull sometimes to foot-operated riding.Therefore, need a kind of energy to adapt to hang down and make children and have more recreational new-type perambulator, to remedy the deficiency of perambulator in the past.

The purpose of this utility model will provide a kind of new-type perambulator that shakes the chair transmission exactly.It becomes foot-operated transmission for shaking the chair transmission on the basis of perambulator in the past.Rock by the front and back that are installed in the rolling chair on the vehicle frame, drive the flywheel unidirectional rotation forward intermittently that is installed on the hind axle by chain, thereby perambulator is moved ahead.

The utility model is achieved in that on the vehicle frame of rolling chair driving type perambulator, be equipped with can before and after the rolling chair that rocks; The middle part of hind axle at it is equipped with flywheel; Between flywheel and hind axle for being fixedly connected, between hind axle and two trailing wheels also for being fixedly connected; Carry out transmission by chain between rolling chair and flywheel.When riding, children are sitting on the rolling chair, hold handlebar, with health rolling chair front and back are rocked, and by the flywheel unidirectional rotation forward intermittently on the chain drive hind axle, thereby perambulator are moved ahead.Lively and lovely animal head type is arranged at the handlebar top of rolling chair driving type perambulator, and for example moulding of duckling head dummy makes it to have more interest.

It is the transmission of rolling chair that the utility model becomes the foot-operated transmission of perambulator in the past, and it is artless and vivacious to adapt to children, the psychology that hobby is hunted for novelty, and being particularly suitable for still can not be with riding the child who rides below three years old; Concerning making big slightly children year, also have more recreational and attractive because of its more traditional perambulator.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is an axonometric drawing of the present utility model.

Fig. 2 is that A of the present utility model is to plan view.

With reference to Fig. 1, Fig. 2, the utility model is by rolling chair (1), vehicle frame (7), hind axle (4), and flywheel (13), chain (2), trailing wheel (3), (5), handlebar (6), front fork (8), front-wheel (9), front wheel spindle (10) is formed.On the vehicle frame (7) of rolling chair driving type perambulator, rolling chair (1) is housed; Connect by bearing pin (14), (15) realization activity between rolling chair and vehicle frame.On the hind axle (4) of rolling chair driving type perambulator, flywheel (13) is housed; The structure of flywheel is: there is a ratchet device inside, and profile is a sprocket wheel, can adopt the flywheel of bicycle.Between flywheel and hind axle for being fixedly connected, between hind axle and trailing wheel (3), (5) also for being fixedly connected.Carry out transmission by chain (2) between rolling chair and the flywheel; The two ends of chain are separately fixed at center (11), (12) of rolling seat support rear and front end.Connect for activity between the front-wheel (9) of rolling chair driving type perambulator and the front wheel spindle (10).On the handlebar (6) of rolling chair driving type perambulator, lively and lovely animal head type (16) is arranged, for example moulding of duckling head dummy, the two ends jug (17) of duckling head dummy, (18).

When riding, children are sitting on the rolling chair, and both hands are held the handle of handlebar, with health rolling chair front and back are rocked.When the rolling chair rocks forward, drive flywheel by chain and rotate forward, perambulator is moved ahead; When the rolling chair rocked backward, chain drove flywheel and dallies backward, and perambulator is motionless, thereby realized travelling forward of perambulator intermittence.The moulding of the duckling head dummy on handlebar top makes perambulator have more interest.
