Description

Children's exercise cycle

The utility model relates to the body-building vehicle of a kind of carriage for children, particularly a kind of children.

Existing perambulator, be generally the foot-operated f-w-d of three-wheel, or the electrically operated four-wheeled of trailing wheel, the former children's sport position is few, does not improve children's interest, and latter's price is higher, the bicycle that also has similar adult in addition, just the single-piece ratio is dwindled, and children's muscle power, capability of reaction, balance are not as adult, accident-proneness.

In the carriage for children of present disclosed 90222093.4 patents, adopt the spring shock absorption structure, make complex structure.In addition, bodywork length, handle height, weight, arm of force length compare etc., do not have the structure of adjustment, child growth phase height is not changed consider.

The purpose of this utility model is to overcome the deficiency in the above-mentioned perambulator, and a kind of simple in structure, good stability is provided, and drives with arm strength, and the perambulator of foot control direction can make children's whole body obtain taking exercise, especially the upper limbs stationary bike for children of partly being taken exercise.

The utility model is to adopt following proposal to realize:

The utility model is made up of front-wheel 14, trailing wheel 7, elastic support 8 and front-wheel elasticity connecting plate 11, driving crank 6, joystick 2 and foot controlled steering device 12, and elasticity connecting plate 11 is housed on front-wheel support, and elastic support 8 is " bow " type elastic construction.

This perambulator adopts foot controlled steering device 12 change of directions, is provided with the net or the plate of protection both feet safety.The activity of perambulator front-wheel tangles on the poroelasticity connecting plate, and is hinged by the different holes with connecting plate of front-wheel center pin 17, the scalable length over ends of body.By regulating rocking bar the position, different hole of screw and fulcrum 3 is installed in addition, can changes the height and position of handle, thereby change the arm of force, weighing arm length ratio, can better adapt to the change of children growth phase height and strength, the applicable area of its perambulator is enlarged.

Further specify the utility model below in conjunction with accompanying drawing;

Fig. 1 is the block diagram of the utility model stationary bike for children;

Fig. 2 is the top view of the utility model stationary bike for children;

Fig. 3 is the lateral plan of the utility model stationary bike for children;

In Fig. 1, can find out that stationary bike for children of the present utility model has graceful moulding and fleetline racing car outward appearance.

In Fig. 2, the 11st, the elasticity connecting plate, the 12nd, foot controlled steering device, both feet step on that the left and right of may command car turns on 12.Foot controlled steering device 12 can be done and reticulate or tabular.The 13rd, front wheel spindle, the 14th, front vehicle wheel, the 17th, the front-wheel center pin, hinged with the different holes on the connecting plate, the scalable length over ends of body.The length over ends of body adjustment amount can be at (being on the perambulator normal position) adjustment ± 60mm on the normal bit.The 10th, seat, the 6th, driving crank shakes joystick 2, by contact 4, connecting rod 5 driving crank 6 is rotated.Make trailing wheel 7 rotate the motion that promotes body-building vehicle thus.The 16th, the station plate that can supply the people to stand, the 15th, hind axle.

The front wheel tread of these children body-building vehicle is 350～500mm, and rear track 400～650mm is in 400～500mm as wheel base, and front wheel tread is equated with rear track, and general situation can make the front wheel tread width less than rear track.To keep a kind of racing car type characteristics.

In Fig. 3, the 1st, the handgrip of holding, the 2nd, joystick by handgrip 1 forward and backward transmission of shaking joystick 2, process contact 4, connecting rod 5, can make driving crank 6 forward or reverse (changeing promptly or the back commentaries on classics), body-building vehicle is travelled forward or drawback movement.The 8th, elastic support can provide elasticity to car load, and the 9th, the backrest of seat.

By regulating the installation screw on the joystick 2 and the position, different hole of fulcrum 3, the adjustable handle height be 80mm and fulcrum up and down variable range be ± 30mm.

This perambulator saves special-purpose spring, spring installation and frame is organic combines beautiful design, simple, novel together; Front wheel tread is less than or equal to track rear, makes vehicle that different appearance and modelings be arranged, and has the characteristics of racing car.

Shake joystick and car is advanced or retreat, do not allow it shake and promptly play braking action.

This perambulator can be driven for children, also can carry in addition on the manned station plate 16 after children stand in seat 10, and two children use jointly.

7, one of trailing wheels are driving wheel, and another is a follower, form differential gear.

Stationary bike for children of the present utility model is owing to adopt the four-wheel structure, rear tread is greater than front tread, center of gravity is low, stability is good, car body is streamline racing car type, children's hand, arm, waist, leg, pin participate in simultaneously, make whole body obtain motion, wheel base, rocking bar length and seat be capable of regulating all, and the children that can be suitable for like this all ages and classes, build use, namely strengthened children's upper limbs power, to temper the harmony of whole body, promote the growth of health, brain, forge manipulative ability, in amusement, take exercises, enlarge one's knowledge.

These children exercycle has beautiful design, simple in structure, advantage firmly in similar carriage for children, adapt to especially 3～10 years old children's amusement and body-building.
