Description

The multifunction folding toy tricycle

The utility model relates to a kind of three-wheeled collapsible perambulator.

Perambulator is the vehicle that the baby plays and goes out to the preschool child.At present, the perambulator on the market of China, sold can be divided into substantially hand propelled child four-wheel van, foot-operated toy tricycle and with three kinds of vehicles such as the hanging van in the matching used limit of bicycle, because above-mentioned perambulator is according to the needs of children's different times and design-calculated, therefore, most heads of a family prepare complete for its children in good time, it is bigger so to change expense, and growth along with children, making some perambulator be eliminated gradually and have shelved, is very big in this waste of one-child family especially; Besides multiple perambulator puts that floor area is excessive again at home, and is very inconvenient.In view of the foregoing, though some people proposes the design plan of many high-mobility, multipurpose, wheeled vehicle perambulators,, because structure is complicated, very not satisfactory.

The purpose of this utility model is at the problems referred to above, its perambulator is designed again, new perambulator has both the function of above-mentioned three kinds of perambulators simultaneously, making it the trinity becomes a reality, the main points of this design are: connect backrest and stand-off face respectively on two tops of seat surface under the body gravity unmodified prerequisite of former perambulator, when three faces during, promptly form 3 faces that couch at same horizontal surface; The upset backrest puts down the stand-off face, is the seat of foot-operated toy tricycle.It is convenient to hang and move on its limit, perambulator left side for the ease of bicycle, and this wheel downward modulation device has been installed at the movable wheel carrier position on the perambulator off hind wheel.

Description of drawings:

Fig. 1: be seat attitude structural representation of the present utility model.

Fig. 2: be the status architecture scheme drawing that couches of the present utility model.

Fig. 3: be the birds-eye view of Fig. 2.

Fig. 4: be the left view of Fig. 2.

Fig. 5,6,7: be respectively that the master that the limit that is installed on the bicycle hangs attaching parts looks, overlooks, scheme drawing is looked on a left side.

The drawing reference numeral explanation:

1 regulates position retaining plate, 2 chassis, and 3 backrests, 4 seat surfaces, 5 tarpaulin after poppets, 6,7 pillars, 8 sheet trestles, 9 tarpaulin front frames, 10 stand-off face supports, 11 handlebars, 12 preceding wheel assemblies, 13 fasteners, 14 movable wheel carriers, 15 hinges, 16 limits hang pipe link.

The utility model is to realize (as shown in the figure) like this: many or can folding type three-wheeled bassinet by front jockey wheel, rear wheel, chassis (2), seat surface (4), handlebar (11) etc. zero, parts form, the two ends of seat surface support (4) and back bracket (3), stand-off face support (10) (this support is two joints) forms four joint structures, before sheet trestle (8) and the tarpaulin, after-poppet (9,5) form three joint structures, all adopt pin to connect between above-mentioned each joint, positioning and locking spare is housed on it, this kind locking member can adopt the dropper location, the screw-type location, directed support-board type location also can adopt coulisse to cooperate realization with bolt. Seat surface support (4), sheet trestle (8) are fixed on the chassis (2) by pillar (6,7). Chassis (2) with Tube connector between the front jockey wheel adopts nested mode to be flexibly connected the positioner that is made up of chute and bolt on it. Be accordion structure between handlebar (11) and the front wheel assembly (12), positioning and locking device is arranged on it, it can be the nested type sliding groove structure. Travel(l)ing rest (14) is contained on the perambulator off hind wheel, its front end is flexibly connected through hinge (15) and chassis (2), the other end has adjusting position retaining plate (1) fixed thereon, and the chassis bolt is contained in the retaining groove of controllable register. The limit hangs connecting rod (16) and is fixed on left side, chassis (2).

Pillar (6,7) respectively is that the metal tube of two joint different tube diameters is formed, and it adopts nested connection mode, and there are chute and lock bolt in its junction.If adopt two joint band irons to replace, then can directly realize being connected with chute and lock bolt.Folding arm rest frame and sunshade are housed on the pillar (6), the cape support keeps off the rain.The go-cart handrail also is equipped with at this kind perambulator rear portion.The limit extension attaching parts that is fixed on the bicycle rear support is made up of clamping plate, bolt, chuck, and it is hung pipe link (16) by the limit and is connected with this perambulator.

Now with using method division of the present utility model following (seeing Fig. 1,2):

1 is foot-operated: the chute internal fixation of wheel assembly before handlebar inserts, and stand-off face support puts down, and backrest lifts, and tarpaulin front frame and folding arm rest frame are turned over and are put a side of tarpaulin after poppet, can use as foot-operated toy tricycle.

2 hand propelled child vans: handlebar is folding, mention stand-off face support, put down backrest, make it with seat surface at grade, again tarpaulin front frame and folding arm rest frame are turned back, can use as van.

3 limits hang bicycle: under above-mentioned van state, the limit in chassis left side is hung pipe link to be fixed on the attaching parts on the bicycle, and the chassis bolt in the adjustment controllable register, off hind wheel and chassis spacing are strengthened, at this moment, this perambulator only off hind wheel lands, so action is very convenient, hangs for the limit of different model bicycle and all can use the controllable register adjustment.When need are taked to sit attitude, the tarpaulin front frame can be turned over the one side of putting the tarpaulin after poppet, stand-off face support puts down, and stand-off face support fwd one joint perk and being placed on the handlebar after folding can realize.

Embodiment of the present utility model:

This car exhibition is opened and is of a size of 900 * 400 * 650mm, and car weight 10kg adopts metal tube, bar and material manufacture such as canvas, leather.

The utility model is apparent than the advantage of prior art, its energy one car is multiplex, possess simultaneously seat, crouch, step on, hang several functions, all age group that all can regulate the preschool child owing to surface height, wheel base can both be suitable for. And aesthetic in appearance, folding convenient, limit hang flexibly, and be again multiplex because of a car, reduces investment outlay, the floor space advantage such as less, is children's a kind of comparatively ideal apparatus. It is particularly useful for having at present preschool child's two-earners family.
