Description

Stationary bike for children

The utility model belongs to sports apparatus class or toy for children class, and it is specifically related to a kind of novel structure that is suitable for the sports apparatus that children use.

Along with the rapid raising of people's living standard, the following situation of the normal appearance of the only-child of general family: 1. because overnutrition grows up to the little rolypoly of overweight; 2. because snacks are too much, the apocleisis phenomenon occur and cause malnutrition.So all influence the normal growing of children, supply and the adjustment with medicine is a kind of way of passiveness separately, and its correct approach is to strengthen exercising, building up health, and forms a kind of normal eating habit and rule of life.But simple exercise is difficult to accept for children, and the health and fitness facilities of using for children must be interesting strong, the attractive and temptation to children.

The purpose of this utility model provides a kind of body-building apparatus---stationary bike for children novel, that be particularly suitable for children, and it has interesting strong, the appropriate characteristics of amount of exercise.

By as above design, the feature of the stationary bike for children that this programme provided is: it is by walking four wheels, pedal, front axle, saddle, front frame, back vehicle frame, extension spring, the pivot pin of vehicle frame before and after connecting, rear axle is formed, its front frame is the form of a single-beam, thereafter vehicle frame adopts the structure of twin beams, saddle is contained in the upper end of front frame, be welded with the pivot pin seat in the back on front frame top, pivot pin just is through in the hole of pivot pin seat and back vehicle frame, be welded with the preceding link plate of spring in the back at front frame middle part, be welded with the back link plate of spring at the middle part of rear axle, extension spring hangs between the link plate of front and back, front frame and front axle connect with preceding pin hinge, its rear axle directly is contained in the hole of vehicle frame lower end, back, between its four wheels and the antero posterior axis freewheel clutch that each wheel of restriction rotates backward is housed all.

In this programme, the single-beam of its front frame connects breeches pipe by the lower end and front axle is hinged.The twin beams of its back vehicle frame has the curved shape of symmetry, and its upper end open is equivalent to children's shoulder breadth, and the opening of its lower end is less than the distance between two trailing wheels.On its preceding link plate of spring, be provided with the ammunition feed spring and select four through holes hanging.Freewheel clutch on its four wheels is the freewheel clutch that adopts ratchet, pawl type, and wherein its ratchet is contained on the antero posterior axis and can not rotates, and its ratchet is contained on the wheel hub.

Adopt this programme can embody following superiority: 1. the front and back vehicle frame of this stationary bike for children is to be hinged with pivot pin, front and back wheel is close mutually under the effect of extension spring again, when children ride on the saddle, because of spring being stretched and making diaxon separately, both feet are pedaled on pedal, front and back wheel is drawn close when firmly two handles being furthered again, because of the effect of the freewheel clutch of front-wheel can not rotate backward, can only be that trailing wheel advances, two-wheeled separately when pulling force reduces, trailing wheel can not rotate backward under the effect of freewheel clutch, and can only be that front-wheel is advanced forward, stretched operation repeatedly, this car just can be walked forward steppingly, this function makes it have the characteristics of toys, has increased exercise in the playing of happiness, and children take like a shot; 2. alternative four holes are arranged on the preceding link plate of its spring, can adjust amount of exercise when changing hitch point, so this apparatus is to the adaptability broad of child age; 3. its front and back vehicle frame, axletree all adopt shape to have the strong rigidity in school, the hinging manner of bearing pin before adopting between front frame and the front axle, so it is also less demanding to surface state, can keep four wheels to land at any time, good stability is arranged, children's safety is had enough guarantees; 4. its simple in structure, low cost of manufacture is convenient to promote the use of.

Fig. 1 is the front view of this programme stationary bike for children.

Fig. 2 is a side view.

The embodiment of existing accompanying drawings this programme.This stationary bike for children by four wheels 1, pedal 2, front axle 3, front frame 9, back vehicle frame 8, rear axle 13, saddle 7, connect before and after vehicle frame pivot pin 6, be welded in pivot pin seat 5 on the front frame, front frame lower end connection breeches pipe 4, connect the hinged preceding bearing pin 12 of breeches pipe and front axle, extension spring 10, the preceding link plate 11 of spring, the back link plate 14 of spring and formed.Its four wheels are contained on the antero posterior axis, and rear axle is contained in two holes of vehicle frame lower end, back; With they hinge-coupled, its pivot pin passes in the hole of pivot pin seat and back vehicle frame the front and back vehicle frame with pivot pin, and the pivot pin seat is welded in the back of front frame; Front frame is a single-beam, and it is by the connection breeches pipe of lower end and preceding bearing pin and before takes out and realize hinge-coupled, also welding pedal on front axle; Be welded with the preceding link plate of spring in the front frame back, be welded with the back link plate of spring in the centre of rear axle, between is hanging extension spring, four selective holes are arranged on its preceding link plate, the freewheel clutch that each wheel of restriction rotates backward all is housed on its four wheels, what this clutch adopted is the structure of ratchet, pawl type, and its ratchet is contained on the wheel shaft and can not rotates, and ratchet is contained on the wheel hub of wheel.

At ordinary times under the effect of spring, draw close mutually between the front and back wheel, when children ride on the saddle, by gravity saddle to be depressed, both feet are pedaled on pedal, the upper end that both hands are held the back vehicle frame is that the handlebar position is drawn repeatedly and put operation, this car promptly automatically moves ahead, and the amplitude of its stretching fast more then this car of frequency big more, operation walks just fast more, adds suitable amount of exercise in being at play, help metabolism vigorous by the exercise can strengthen children physique, impel its blossom out; Its spring can be realized the adjustment of exercise load by changing hitch point, therefore age of children is had the adaptability of broad; This car can have the effect of balanced exercise to the muscle of children's whole body in use, and it can also advance interesting by force steppingly simultaneously, and children is very easily accepted.The pilot sample of this programme uses proof through experiment: it has, and interest is strong, movement effects is good, less demanding to the athletic ground, wide to user's age adaptability, the characteristics of low cost of manufacture, is subjected to the welcome of children deeply.
