Abstract

The utility model designs a two-power health-care bicycle for children, which is composed of wheels, a bicycle body and a seat cushion, wherein, the bicycle body is formed by hinging two X-shaped steel frames at the middle part, and two rear wheels are respectively connected with both sides of the rear lower feet of the steel frames. The front feet are provided with two front wheels and driving foot pedals, and the front wheels can rotate around the middle point of a wheel shaft. A seat and a handrail are arranged on the fork of the upper part of the X-shaped steel frames, and a power spring is arranged between the seat and the rear feet. In this way, when the children ride on the seat cushion, the bicycle can be moved forward both by treading the foot pedals with feet and by pressing armrests with hands. Simultaneously, the X-shaped supporting frames move up and down around the supporting point in an open and close mode under the gravity function. Since the wheel arranged on the supporting feet is provided with a non-return device, the bicycle only can move forward. When the X-shaped bicycle frames are opened and closed, the bicycle body moves forward.

Description

Double dynamical stationary bike for children

The utility model belongs to the improvement of toy for children class, particularly a kind of stationary bike for children.

Existing perambulator is common generally is divided into two-wheeled or three-wheel, by pin collapse wheels or chain, vehicle body is advanced or retreats.Children not only can temper the coordination ability of trick, and can temper its leg power when riding this perambulator.But children move more singlely in the process of advancing to pedal, and the muscle at other position of health (as waist) can not fully be taken exercise except shank.

The purpose of this utility model is a kind of double dynamical stationary bike for children of design, during use except driving with pin the front-wheel, the power that can also advance as vehicle body with hand and waist can make each position of children's whole body all can obtain taking exercise, and trains the coordination ability of its hand, pin, waist simultaneously.

The technical solution of the utility model is: a kind of double dynamical stationary bike for children, comprise wheel, vehicle body and seat cushion, vehicle body is linked in the middle by two " X " shaped steel frames and forms, the back leftover bits and pieces of " X " shaped steel frame forms a bifurcated, both sides link respectively two trailing wheels, have a wheel shaft to link between two front-wheels, the front and back four wheels all is provided with the unidirectional mechanism that can only advance; The forward foot in a step of " X " shaped steel frame is attached at the mid point of this wheel shaft by rolling bearing, and promptly the preceding wheels that linked by wheel shaft can rotate around this wheel shaft mid point, left and right sides front-wheel be respectively equipped with outward drive foot-operated; Seat cushion is installed in the back of " X " shaped steel frame and goes up on the pin, and the preceding pin of going up of " X " shaped steel frame is equipped with handrail; " X " shaped steel frame power spring is housed between the rear foot up and down.

Like this, when child rides on the seat cushion, make vehicle body advances except spoiling with the pedal pin, also available hand is pushed handrail downwards, and under the effect of power spring, " X " shape support is done open and close movement up and down around its fulcrum, because the wheel on the leg has non-return device, can only cause " X " shape vehicle frame in folding forward, vehicle body be advanced forward.

This stationary bike for children carries out comprehensive reform with existing perambulator, action novelty above children ride over, interesting strong, when making children produce enjoyment at the volley, body parts such as waist, leg, arm all obtain taking exercise, and can take exercises the coordination ability between each position simultaneously.

Fig. 1 is the overall structure schematic diagram of this perambulator.

Fig. 2 is front-wheel of this perambulator and foot-operated STRUCTURE DECOMPOSITION figure.

Describe in detail below in conjunction with accompanying drawing.As shown in Figure 1, vehicle body 1 is " X " shape, is that two steelframes link together in the centre, can rotate the action of similar scissors around fulcrum 6.The back leftover bits and pieces of " X " shaped steel frame forms bifurcated, and both sides link respectively two trailing wheels 2.A common wheel shaft is arranged between two front-wheels 5, and the forward foot in a step of " X " shaped steel frame is attached at the mid point of this wheel shaft by rolling bearing 7, and promptly the preceding wheels that linked by wheel shaft can rotate around this wheel shaft mid point.Front-wheel 5 outer being respectively equipped with in the left and right sides ride 8, are used to control the direction of vehicle body.Seat cushion 3 is installed in the back pin of going up of " X " shaped steel frame, support a power spring 4 is housed between the rear foot up and down.Handrail 9 is installed in the preceding pin of going up of " X " shaped steel frame.

A key character of this car has been that the front and back four wheels all is provided with the unidirectional mechanism that can only advance, and so just guarantees pushing handrail downwards with hand, and " X " shape support is let go the back under the effect of power spring after closure before and after its fulcrum, and vehicle body is advanced forward.

Fig. 2 is the STRUCTURE DECOMPOSITION figure that front-wheel of this perambulator and pin are spoilt.Among the figure structure of visible the near front wheel be set with successively from left to right on wheel shaft 10 that pedal crank head hold-down nut 11, locking nut 12, wheel cap 13, stage clip 14, clutch and brake pepperyly take turns 15, wheel disc 16 etc.Pedal crank head hold-down nut 11 all is provided with internal thread with locking nut 12, can be tightened on wheel shaft 10.Locking nut 12 is provided with the interlock tip, and the outside of wheel cap 13 has the groove that can embed this interlock tip, and locking nut 12 drives wheel cap 13 rotations by the interlock tip like this.Peppery 15 centers of taking turns of two mutual interlocks have the cross shrinkage pool, and the left side of wheel cap 13 right sides of both sides and wheel disc 16 all is provided with the cross projection 17 that can embed this shrinkage pool, and stage clip 14 is located between wheel cap and peppery the wheel.

Front-wheel wheel shaft 10 is through the power rotation axis between two front-wheels.Wheel outer shaft sleeve between two front-wheels has sleeve pipe 19, also is with nylon sleeve 18 between sleeve pipe 19 and the wheel shaft 10, dies of a sudden illness in the wheel shaft rotation process preventing.Steering spindle 20 is located at the mid point of sleeve pipe 19, and preceding wheels can be around its flexible rotation.

Like this, foot-operated by stepping on, make the locking nut rotation, rotate thereby drive wheel cap by the interlock tip, drive peppery the wheel and the wheel disc rotation by the cross projection in the wheel cap inboard again, thereby wheel is advanced.When riding backward rotation, the peppery wheel skidded, and rides and can not drive front-wheel.
