Abstract

The utility model relates to a multiple-drive bicycle for children. On the basis of a common three-wheeled bicycle for children, a frame structure can be changed to two-body type which can rotate correspondingly; a flywheel and a chain are added on a rear shaft; the reciprocating movement of the chain can be realized; the flywheel can be driven to rotate; finally, the whole bicycle can be driven to forward. The utility model can be used as an ordinary bicycle advancing through pedaling and riding; the utility model can also be used as a rider horseback riding type for advancing through skipping; the utility model can be used for advancing with the rowing type. The utility model has two functions of entertainment and physical body building. The utility model has obvious functions for exercising waist, back and the strength for children and reinforcing the physique.

Description

Multiple-drive bicycle for children

The utility model relates to a kind of carriage for children, and specifically a kind of available multiple mode drives the perambulator that advances.

Existing perambulator kind is more, but function is comparatively single, can not satisfy children and move curiosity, interest characteristics widely more.The structure of common perambulator has generally comprised handlebar, front fork, pedal, front and back wheel, saddle, rear axle and vehicle frame etc., and its type of drive is the single mode of foot-driven.

The purpose of this utility model just provides a kind of perambulator new construction with multiple type of drive, the demand that changes with the amusement variety that satisfies children.

The utility model is achieved in that on the basis of common toy tricycle changing body frame structure for automotive is two bodily form formulas, and can relatively rotate, install flywheel and link chain mechanism on the rear axle additional,, realize the crank motion of chain with spring traction vehicle frame and chain, the rotation of drive flywheel finally drives car load and advances.The driving that can realize two or more modes is advanced thus.

Below in conjunction with accompanying drawing utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a kind of deformation state figure of the present utility model.

As shown in Figure 1, the structure and the fit system of parts such as the handlebar 1 of this perambulator, front fork 2, pedal 3, front-wheel 4, saddle 5, rear axle 11, two trailing wheels 10 and existing perambulator are basic identical, and vehicle frame is connected to form by rotating shaft by herringbone beam 7 and support 8.Herringbone beam 7 has level frame and declivity frame.Saddle 5 is housed on the level frame, and its front end is fixed on the front fork 2.The upper end of support 8 is fixed with the intubate 15 that can buy car in installments and insert to 1, its bottom is connected on the rear axle 11, be connected to spring 13 between the lacing film of lacing film in the middle and herringbone beam's declivity frame bottom, flywheel 12 is housed on rear axle 11, the chain 9 one that is enclosed within on the flywheel is terminated at herringbone beam's declivity frame bottom, and the other end is connected to herringbone beam's declivity frame bottom by spring 14 after connecting spring 14 again.When children were seated on the saddle, foot-operated pedal 3 can realize that traditional pedaling ride type of drive.This perambulator great-jump-forward of also can realizing riding drives, promptly when saddle bears a heavy burden, sinks naturally, and herringbone beam 7 declivity frame bottom reach, the chain 9 that joins with this bottom moves forward thereupon and drives the flywheel rotation, is rotated by flywheel drive rear axle and trailing wheel, and vehicle is advanced.When children erected, spring 13 was pulled back declivity frame bottom, makes the saddle upper fin, and simultaneously spring 14 is oppositely strained chain.So walking vehicle makes the effect with body weight for humans power up-and-down movement perambulator finish above-mentioned action again and again, promptly advances as horseback riding type ground.

In Fig. 2, the perambulator integral structure remains unchanged substantially, just handlebar is extracted from front fork 2, inserts in the intubate 15 again, and chain 9 takes off knot with the end that herringbone beam's declivity frame bottom joins, and the lacing film with intubate 15 bottoms joins again.Be seated at like this on the saddle, return and remove handlebar, make the bottom reach of intubate 15, the same principle drives the chain reach, flywheel, rear axle, trailing wheel is rotated advance.Walking vehicle is loose power then, and spring 14 retracts chain 9 and intubate bottom, constitutes the one-period motion, moves handlebar as the shape of rowing the boat so repeatedly, can make this perambulator continue to advance.

In this perambulator, saddle 5 is connected with herringbone beam's level frame by the slip underframe 6 that is fixed on its bottom, can regulate the front and back position of saddle thus according to children's different heights, makes it the degree that reaches comfortable.

This perambulator had both had recreational, also can realize the purpose of body-building, and children are tempered waist, the back of the body and arm strength, and increase lung capacity etc. all has tangible effect.

Claims

1, a kind of perambulator that drives more, include handlebar 1, front fork 2, pedal 3, front-wheel 4, saddle 5, rear axle 11, two trailing wheel 10 and vehicle frames, it is characterized in that vehicle frame is connected to form by rotating shaft by herringbone beam 7 and support 8, herringbone beam 7 has level frame and declivity frame, saddle 5 is housed on the level frame, its front end is fixed on the front fork 2, the upper end of support 8 is fixed with the intubate 15 that can buy car in installments and insert to 1, its bottom is connected on the rear axle 11, be connected to spring 13 between the lacing film of lacing film in the middle and herringbone beam's declivity frame bottom, flywheel 12 is housed on rear axle 11, the chain 9 one that is enclosed within on the flywheel is terminated at herringbone beam's declivity frame bottom, and the other end is connected to herringbone beam's declivity frame bottom by spring 14 after connecting spring 14 again.

2, the perambulator that drives according to claim 1 is characterized in that saddle 5 is connected with herringbone beam's level frame by the slip underframe 6 that is fixed on its bottom more.
