Description

The travelling draw-rod suitcase of collapsible expansion

Technical field

The present invention relates to a kind of travelling draw-rod suitcase of collapsible expansion.

Background technology

At present the scope of application of draw-bar box very extensively, it has vertical vertical contour structures, also is equipped with in addition a pair of or two pairs of wheels that can slide on the ground, and the traction handle that can prolong.

Although their use is very universal, people still constantly increase the requirement of this class luggage case, that is, need to its dimensions be limited.

Its tangible a lot of places of the problems referred to above all can be mentioned, no matter be in family, when people need to deposit a temporary transient no luggage case, or in " use procedure ", for example working as you need to be placed on luggage case in the cargo hold, or place on the aircraft on the luggage carrier of luggage, or be placed in the boot of automobile, or be placed on the luggage carrier of train.

In fact just there has been the draw-bar box produced for these specific demands before should saying, namely had this such structure that can shrink expansion that is similar to a little bellows device.

Because similar conceptual design has been arranged, in fact, as people without draw-bar box the time, it more reasonably can be shunk deposit (namely it being retracted to minimum gauge) in the built-in wardrobe or on the shelf fully.But, in fact, even when using it, too can be in the situation of the article that hold some, reasonably contraction is stored within the foregoing minimum gauge spatial dimension.

But, if in the time of need to leaving the number of articles of cabinet interior in and exceeded above-mentioned its minimum internal capacity, a similar draw-bar box that can shrink expansion, according to its contraction extension principle of little bellows, be easy to its inner space expansion is widened, in itself its expansion increased to its inside heap(ed) capacity scope.

The existing draw-bar box that can extend expansion, half shell-like structure of normally being made by two relative hard materials consists of, and between these two half-shell structures, reinforces shroud by four limits of a material softness and is connected, and described shroud is made with cloth usually.

From this aspect, be readily appreciated that the effect that above-mentioned four limits that are present on the centre position reinforce shroud.Just because of this, the characteristic of above-mentioned little bellows is set, in fact can limits the distance of above-mentioned two half-shell structures, be used for respectively increasing or reducing the capacity of draw-bar box the inside.

For the structure of the draw-bar box of understanding better existing collapsible expansion, shown in Figure 1A, this draw-bar box T1 that can shrink expansion type has two slide fasteners 10,20.Article one, slide fastener 10 is installed on the edge that is connected to the opening part around the chest, with above-mentioned with soft material make around to reinforce shroud 30 corresponding, be positioned near the edge of first half shell 40 among two half-shell structures.

When needs were put into or take out different article, slide fastener 10 can alternately open and close whole draw-bar box T1.

Second slide fastener 20 is installed in around draw-bar box T1 itself whole, be designed to the distance between above-mentioned two half-

shell structures

40,50 furthered or away from.

In fact, if want to allow the overall structure of draw-bar box T1 be in when shrinking the compact structure state, above-mentioned slide fastener should be closed.In this case, make above-mentioned made four limits in the centre of soft material of using reinforce the maximum collapse amount that shroud 30 obtains between two half-

shell structures

40,50.

As shown in Figure 1B, when only having four limits of the soft material in the middle of need to extend elongating above-mentioned being positioned to reinforce shroud 30, just need pull open above-mentioned slide fastener 20, thereby allow two half-

shell structures

40,50 distance increase, whole draw-bar box T1 expansion is increased, reach the heap(ed) capacity of corresponding cabinet interior.

Just as shown in Figure 1B, wherein zip teeth 20a one end of second slide fastener 20 is made near the position of above-mentioned article one slide fastener 10, and an other zip teeth 20b makes near the side seam of second half-shell structure 50 in above-mentioned two half-shell structures.

That is to say, in the prior art, two above-mentioned

slide fasteners

10,20 arrangement positions that present side by side, wherein article one slide fastener 10 is positioned at first hard half-shell structure 40 1 sides, and second slide fastener 20 then is positioned at a side of second hard half-shell structure 50.

So, be widely used although have to admit a kind of like this similar techniques, yet it must be noted that, by side by side slide fastener 10 of above-mentioned two of mentioning, 20 setting, make it equally also exist the defective that can not be ignored just.

In this case, in fact, remove the deformability that four limits of being made by soft material in the centre position reinforce shroud 30 that is positioned at above-mentioned, also limited significantly in addition the possibility of the contraction of each draw-bar box T1.

In fact be readily appreciated that the shrinkage that this four limits of being made by soft material reinforce shroud 30, particularly when two half-

shell structures

40,50 are closing the distance, can find an obvious obstacle, be considered to mutually be caused by described two slide fasteners that are arranged side by

side

10,20, have influence on two hard half-

shell structures

40,50 relative marginal positions itself; In Figure 1A, be confirmed again about this point.

In a word, this means between described two half-shell structures that separate 40,50 keeping a distance of separating that side by side slide fastener 10 of this distance and two, 20 overall width distance are complementary.

Summary of the invention

Carry out careful analysis and assessment for this situation, produced the design of draw-bar box of the present invention, and according to suggestion of the present invention, overcome well defective of the prior art, more particularly, can make the contractility (namely dwindling on specification) of draw-bar box itself be significantly higher than the product of the conventional model of corresponding tradition.

Emphasize especially the advantage of the function of this increase amount of contraction, the draw-bar box of especially small-sized specification, (being commonly referred to as " cabin luggage ") is very suitable for those and gets used to draw-bar box is with the people who boards a plane as hand-baggage.

Because as airline, under the policy of compression Cost reduction, also be intended to reduce step by step to bring into the specification of the draw-bar box that loads in the cabin.

In fact can expect, in this respect, some airline so-called " low cost " operation, even only allow those hand-baggage that highly is no more than 20 centimetres are brought in the cabin.

Further purpose of the present invention is, according to the draw-bar box that can extend expansion of the present invention, not only has more compact structure, comes compared with similar traditional draw-bar box, attempts in the situation of picking lock when running into the someone, and it is more solid firm and not fragile.

In this similar situation, in fact, want illegally to open luggage case if there is the people to nourish malice, all must have to these two different slide fasteners are opened simultaneously, and unlike traditional draw-bar box, only need pull open a slide fastener.

These above two purposes are to be based upon on the structure of draw-bar box, make every effort to the general structure basic simlarity with traditional classification, but but change in the installation site of above-mentioned two required slide fasteners.

A kind of travelling draw-rod suitcase of collapsible expansion, comprise a pair of relative half-shell structure, four limits that are positioned at the middle part are installed between these two half-shell structures reinforce shroud, this reinforcing shroud is to be made by soft and solid material, and be equipped with article one slide fastener, this slide fastener links together with its opening part edge all around and is corresponding with it; Especially, two slide fasteners according to draw-bar box of the present invention no longer are to lay side by side, but slide fastener be placed in another slide fastener above, be exactly specifically, one (refer to four limits of being made by soft material with mid portion reinforce shroud links together and keep consistency) be positioned at the position of more close the inside, and another (refer to and can make two hard half-shell structures widen expansion) is then on the position of outside more.

In fact, this solution obtains by linking together near the edge that determines the hard half-shell structure that the teeth component of two zips of above-mentioned second slide fastener (be used for expand with shrink draw-bar box use) is relative with two.

This that is to say, the teeth component of two zips of second slide fastener be connected to above-mentionedly be positioned at the centre position of two half-shell structures, four limits of being made by soft material reinforce on the shroud.

By this way, in case meet above another for one in two half-shell structures, and the four limits reinforcing shroud that middle soft material is made " is extruded " between them, the result who obtains is exactly that above-mentioned second slide fastener will be controlled four limits reinforcing shroud and the slide fastener relevant with it that above-mentioned soft material is made from the outside.

Can say that also this two slide fasteners are substantially overlapping dischargings, in this case, the slide fastener that four limits made from soft material reinforce shroud is installed in the position of the inside, and the slide fastener that connects two half-shell structures then is installed in outside position.

Because the similar overlapping placement of above-mentioned two slide fasteners mentioning, therefore might make two half-shell structures obtain to further to a greater extent, because their translations towards another one, the result is just hindered by second slide fastener noted earlier, and no longer is that (as aforementioned prior art) hindered by two slide fasteners.

The specific embodiment

With reference to these accompanying drawings, what described draw-bar box T adopted usually is by the made a pair of relative half-

shell structure

4,5 of hard material, four limits that are positioned at the centre position are installed between two half-shell structures reinforce shroud 3, made by soft material, be used for the connection between two and half shells itself 4,5.

Draw-bar box of the present invention also is to have adopted two coverings slide fastener 1,2 all around.

Article one slide fastener 1 in the above-mentioned slide fastener, the edge that reinforces the peripheral openings place of shroud 3 with four limits that are positioned at the centre position mentioned above links together, and corresponding with it.That is, article one slide fastener 1 is used for controlling opening and closure of whole draw-bar box T, and draw-bar box is widened configuration state after the expansion, shown in Fig. 2 B and Fig. 3 B.

On the contrary, second slide fastener 2 is used for also shrinking so that above-mentioned four limits that are positioned at the soft material of mid portion reinforce shroud 3, shown in Fig. 2 A and Fig. 3 A when wanting to make above-mentioned two half-

shell structures

4,5 to remain retracted them hithermost the time thereupon.

For the above reasons, the 2a of teeth branch, the 2b of two zips of second slide fastener 2 are sewn to above-mentioned four limits that are positioned at the softness of mid portion and reinforce on the shroud 3.

More precisely, the 2a of teeth branch of one of them zip of second slide fastener 2 be sewn on first hard material half-shell structure 4 around on the outer rim, and corresponding with it, and the 2b of teeth branch of an other zip be sewn on second hard material half-shell structure 5 around on the outer rim, and corresponding with it, very clear and definite showing in Fig. 2 B and Fig. 3 B.

Because these similar designs, second slide fastener 2, when needs are closed around draw-bar box T whole, formed the structure of a relative pinch confinement, overlap onto the outside of above-mentioned article one slide fastener 1, until fully it and the relative four limits reinforcing shroud 3 that is positioned at the softness of mid portion are stashed fully.

But prior it should be noted that, consider two such slide fasteners 1,2 similar overlapping placement, mean and only have second slide fastener 2, in the middle of namely outside slide fastener can be placed on, thereby between two half-

shell structures

4,5, produce a thickness, in fact half-shell structure itself is extruded contraction simultaneously, specifically sees shown in Fig. 2 A and Fig. 3 A.

Say that as the front this design can allow whole draw-bar box T in the situation of maximum collapse amount, hold the maximum degree of depth.

Here to further specify, in view of the contraction of whole draw-bar box T, when needs reduce inner amount of space, can open in due course four limits that are installed in that material softness on the centre position noted earlier and reinforce article one slide fastener 1 on the shroud 3.

Like this, in fact can not bring any type of opposite problem, because the closure place of draw-bar box T, or two half-

shell structures

4,5 connection can guarantee fully, depend in a word the closure of above-mentioned second slide fastener 2.

Here further explicitly point out at last, up to the present, according to the present invention, usually the draw-bar box T of the half-shell structure of two hard materials is used in suggestion, the half-shell structure that can use too the design of these innovation and creation to utilize two soft materials to make (is used leather, fabric or similar material) make draw-bar box, perhaps also can form with the half-shell structure of a hard material and the half-shell structure of a soft material.
