The head and the wheels of the combined children's cycle can use components of the existing children's tricycle, the frame structure can be bent into a body by using shapes, the front section of the frame structure is near the front wheel, the back section of the frame structure is near the ground and parallel to the ground. The utility model has the advantages of simplicity and reasonableness, convenient assembly and disassembly, stability and safety.

Description

Combined children's cycle

The utility model relates to a kind of combination perambulator.

Be suitable for children, particularly 3 to 8 years old used perambulator of children has three-wheel vehicle on market, two-wheel bicycle and two-wheel scooter.With advancing age, children's mobility and interest can change.Existing perambulator is fit to wherein a kind of mobility of children or interest, and can not satisfy the requirement of children in different interest stage or mobility.

The utility model is exactly to design for the deficiency that remedies existing perambulator.Design objective is to provide a kind of can adapt to children ' s activity ability and interests change, the combination perambulator of one-object-many-purposes.

Task of the present utility model is finished by following proposal:

The combination perambulator comprises front-wheel, handlebar, front fork, trailing wheel and the rear axle of band pedal rotating shaft, the vehicle frame of being made up of front fork sleeve, back vent and frame body.With the frame body that section bar is bent into, leading portion is near front-wheel, and front end and front fork sleeve weld, and then near ground and parallel to the ground, the rear end is connected with back vent back segment.A, a trailing wheel are in the middle of back vent two arms; B, two trailing wheels are respectively in the outside of back vent two arms; C, a pedal are fastened on vehicle frame part parallel to the ground; D, the rigid support that has a saddle are fastened on the vehicle frame.They have following array configuration: ac, ad, bc, bd, acd, bcd.

Wherein ac is combined into a two-wheeled scooter, and ad is combined into a two-wheel bicycle, and bc is combined into the scooter of a three-wheel, and bd is combined into the bicycle of a three-wheel, but acd is combined into the two-wheel bicycle of loading, but bcd is combined into the tricycle of loading.

Headstock and wheel can be selected the kind of selling on the present market for use.Improvement of the present utility model is vehicle body and back vent, and they are made with section bar, generally uses the round iron pipe.

The utility model can provide two kinds of interchangeable back vents, realizes the assembled scheme of a or b, and a kind of is the back vent that is suitable for single-wheel, and another kind is to be suitable for the two-wheel back vent.Back vent adopts removable Bolt Connection in the vehicle frame rear end.

The utility model can also be realized like this: back vent by with the cross bar (13) of vehicle frame rear end welding, being arranged symmetrically in the hosel (12) at cross bar two ends and the yoke (10) of pair of curved forms, the yoke rear end has cross through hole to join rear axle (11), and the yoke front end is plugged among the hosel (12).When a, two yoke rear ends are drawn close the symmetry grafting to the midline, join short rear axle; When b, two yoke rear ends are arranged the symmetry grafting to the left and right, join long rear axle.

Yoke (10) and hosel (12) are used bolt.

The utility model is compared with existing product, and following advantage is arranged:

1, simple in structure, retail price is equivalent to toy tricycle on the market; 2, assembly highly versatile, existing perambulator factory is easy to tissue production; 3, one-object-many-purposes can adapt to the variation of the mobility and the interest of child growth different phase; 4, make the best use of everything, alleviate the head of a family's economical burden; 5, under the guidance of being grown up, children can oneself assemble, and ability and inspiration children ' s creative thinking that the cultivation children are done yourself have positive effect.

Fig. 1 is about embodiment bc combination of the present utility model.Long and short dash line is depicted as the state of ac combination.

Fig. 2 is that long and short dash line is depicted as the state of ad combination about the bd combination.

Describe in further detail in conjunction with the accompanying drawings:

Attached Fig. 1 and 2 is four kinds of main combinations about the utility model most preferred embodiment.This example adopts the headstock and the wheel of existing perambulator, and trailing wheel (9) is littler than front-wheel (6).The frame body (5) of vehicle frame becomes with a steel tube bending, and frame body leading portion is near front-wheel (6), and front end and front fork sleeve (2) weld.Back segment is then near ground and be parallel to ground, overhead with trailing wheel (9) radius with high, welding has two arms (13) of hosel (12), symmetric arrangement about the rear end.Two yokes (10) of back vent curve draw back Z-shaped with steel pipe, and front end is plugged among the hosel (12), uses bolt, and there is cross through hole the rear end, and rear axle (11) runs through it

When two yokes (10) rear end is drawn close the symmetry grafting to the midline, join short rear axle, a trailing wheel (9) is between two yokes, and meson and spring cotter location are joined in the rear axle two ends, become a two-wheel car.Short rear axle does not draw in the accompanying drawings specially.

When two yokes (10) rear end is arranged the symmetry grafting to the left and right, join long rear axle (11), two trailing wheels (9) are in the outside of yoke, and meson and spring cotter location are joined in rear axle (11) two ends, become a three-wheel vehicle.

Two through holes that frame body (5) back segment part parallel to the ground is opened in advance are with bolted connection fixed pedestal (14) or saddle pillar (15).Frame body front end also is welded with bracket sleeve tube (4), can tightly overlap the location to the saddle pillar front end.

Saddle pillar (15) curves trisquare shape with steel pipe, and the front end inserting is in bracket sleeve tube (4), and the rear end is welded with otic placode (17) and fixes with the through hole bolt together of frame body (5) rear end, and saddle (16) is made with plastics, timber etc., is fixed on the support.

Pedal can have gripping pattern on (14), generally makes with steel plate, is welded with otic placode (8) and vehicle frame bolt together below.

Product can or external member sell.Inventory is as follows: connects the vehicle frame of headstock, the support of saddle arranged, and pedal, two yokes of back vent, two rear axles, long rear axle, short rear axle and some annexes, annex comprises bolt, meson, spring cotter can also attach wrench.
