Description

Satchel type speed folding carriage for children

The utility model belongs to the physical construction technical field.

The applicating history of child's car for a long time.Child's car kind of selling on the market at present, is more.Have medium-sized, luxury, the stair climbing type, multifunctional etc.These child's cars generally can fold.Shape after folding, have two kinds basically: a kind of is flush type.Most child's cars all are folded into this style.Another kind is the shape that is folded into two big umbrellas.With coventional type child car, the size that is folded into behind the flush type is about long 75 centimetres, wide 42 centimetres, thick 22 centimetres.To use certain more luxury child's car, the size after folding is about long 87 centimetres, wide 38 centimetres, thick 27 centimetres.And the weight of existing child's car is generally all heavier.From the above, the folding main purpose of all child's cars is to be convenient to family place when withdraw from use at present.For out carrying is very inconvenient.

The utility model provides a kind of and can fast folding becomes undersized, in the satchel of packing into, portable child's car.Except using at home, (as go to the park, the friend family of going into the street, call on relatives, take advantage of bus, high-rise building etc. up and down) can be carried when going out, and promptly where child walks, and where car takes to.Like this, just omitted and had the manual labor that child works hard at any time in arms.

Satchel formula fast folding child car is made up of vehicle body, handlebar and wheel three parts, as shown in Figure 1.Vehicle body is mainly by member (1)～(7), (11) of flat rectangular cross section, trapezoidal plate (19), compositions such as dull and stereotyped (15), (18), (20).Handlebar (9) is the pipe section, but with member (7) junction be the flat tube section.Four wheels adopt the cardan wheel that the plane thrust ball bearing is arranged.

The folding operation process is as follows: (8) take off handlebar (9) from the junction earlier; With folding 90 ° of four wheels, make the wheel disk parallel with the car baseplane; (4) disconnect (totally four) with horizontal member (3) and (6) from the junction, and each is superimposed with forked members (1), (7), (17).Forked members is a fulcrum with the connection hinge on the trapezoidal plate, and is all folding to the headstock direction.

Realize small size, fast folding at the utility model below, planform is variable etc., and problem is described in detail.

Trapezoidal plate (19): it is a primary element of realizing the small size fast folding.Its effect has three: (1) both coupled together forked members securely, can dwindle one times to the vehicle body folded size again.(2) microcephaly of trapezoidal plate is preceding, major part after, making between the member of folding back has certain interval, to hold the thickness of wheel, makes folding smooth.(3) because 2 members in rear portion (17) length of forked members is shorter, the forward and backward wheel in folding back is staggered, unlikely overlapping, reduce thickness; And 2 members (7) are longer because of linkage section is arranged, and just in time flush with front end after folding, and dwindle folded length.

Attaching parts (4): it is a channel member.One end and member (6) riveted joint, the other end adopt the double bolt of band spring to be connected with member (3).During joint, member (3) gently is pressed in the groove of (4), two latches insert in the hole of (3) under the elastic force effect.Pull out latch when folding, member (3) just disconnects.Adopting the double bolt structure is for solid and reliable.

Connecting piece (8): handlebar adopts tooth bar to mesh (interlock) structure with being connected of member (7).During connection handlebar is inserted in the toothed linkage section of member (7), promotes the key piece, the two tooth bar interlock.Only need the backspace key piece during dismounting, just desirable handlebar down.

Vehicle wheel frame (13): it adopts two fulcrum structures with being connected of last transverse plane thrust ball bearing.A fulcrum is that hinge connects, and another fulcrum is that spring tongue connects.Pull out latch, wheel just is that fulcrum is folding with the hinge.During expansion vehicle wheel frame is removed directly, latch inserts voluntarily.Adopt two fulcrum structures solid and reliable.

Backrest (15) is supported in support (16).The plank (20) that again folding is put under the seat (18) is routed up, and the bolt bar rest below seat (18) just can become long 57 centimetres bed.Annulus (21) and cross bar (18) are used for an extension mosquito net.

When without this child Che Shi, top two members (3) and (6) are disconnected, fold towards following commentaries on classics member (1), (3), member (6) is connected with spring tongue with support (22), remove seat and cross-arm thereof and backrest, just become the baggage car of right-angled triangle vehicle body or the car of purchaseing grain, buy vegetables.Carry, use all and make things convenient for.Because the design's sound construction is so there is certain load-carrying capacity.

The utility model is selected density little (gently) for use, is had the material manufacture of certain mechanical strength and rigidity.Can be made into middle-grade product.

The utility model is compared with existing other child's car, and its advantage is:

(1) in little, the satchel of can packing into of folded size, in light weight, be easy to carry.Satchel is of a size of high 32 centimetres, wide 28 centimetres, thick 11 centimetres, as shown in Figure 2.

(2) folding or launch fast, but in half a minute complete operation.Skilled back required time is shorter.

(3) can be transformed into baggage car or shopping cart easily.Sound construction has certain load-carrying capacity.

Claims
