Description

Scalable knapsack

[technical field]

The utility model relates to a kind of mankind life article, relates in particular to a kind of scalable knapsack.

[background technology]

At present, the knapsack on the market generally is made up of inclusion and braces.

A kind of knapsack (notification number: CN2537262 is disclosed at Chinese utility model patent specification, the day for announcing: on February 26th, 2003), its clip Text is as follows: a kind of knapsack, comprise the preceding width of cloth, the middle width of cloth that constitutes knapsack, the back panel that has braces, link together by slide fastener between the width of cloth and the middle width of cloth before its special feature is.The utility model compared with the prior art, having the user can be according to different occasion arbitrary combination knapsack, uses needs, simple in structure, advantage of low manufacturing cost to satisfy.

Above-mentioned knapsack has the characteristics of arbitrary combination, but, knapsack is not using, and when it is shelved, can take bigger space because of its intrinsic volume is excessive, thereby a kind of existing fixed volume capacity, the knapsack that shared volumetric spaces is littler than actual volume again when not using or shelving become the present pericervical sore business men technical issues that need to address.

[utility model content]

The technical problems to be solved in the utility model is to overcome above-mentioned defective, and a kind of existing fixed volume capacity is provided, littler than the actual volume again scalable knapsack of shared spatial volume when not using or shelving.

For solving the problems of the technologies described above, the utility model is taked following scheme:

A kind of scalable knapsack, have inclusion and braces, it is characterized in that: described inclusion is connected to form by loam cake, waist and base, described waist is made by collapsible lining and is connected loam cake and base, base is connected with braces, and a rotating rotating disk is installed at the top of loam cake, upwards is distributed with some expansion strips (band) in the footpath of inclusion outer surface, one end of described expansion strip (band) is installed on the rotating disk, and the other end is fixed on the base.

Loam cake wherein adopts material of greater hardness (for example hard plastic) to make, and, radially evenly offer several guide grooves at last exterior surface, expansion strip (band) can be placed in the guide groove, as a kind of preferred version, the number of guide groove is identical with the bar number of expansion strip (band), the corresponding expansion strip (band) of guide groove.

As a better mode, guide groove wherein has three～ten, expansion strip (band) is corresponding with the quantity of guide groove, be embedded with an expansion strip (band) in each guide groove, one end of each expansion strip (band) is installed on the rotating disk, and the other end is fixed on the base, by the rotation of rotating disk, make expansion strip (band) tighten up or decontrol, and make base near or away from loam cake.When base during near loam cake, the waist of being made by collapsible lining tightens, the smaller volume of whole knapsack; When base during away from loam cake, the waist of being made by collapsible lining unclamps, and when the amplitude of unclamping was maximum, it is maximum that the content volume of knapsack reaches.

And as a kind of priority scheme, handle is installed on rotating disk, one location device is installed on handle, this positioner is a location button, pressing navigation button can rotate rotating disk, and after driving knapsack and tightening or unclamp certain position, unclamp navigation button rotating disk is no longer rotated, play the effect of location rotating disk.

Offer a strip opening in base bottom, opening is by slide fastener or easy-to-drawly buckle stitchings, by this opening, in the thing threading knapsack that can place needs.

The utility model reaches the purpose that knapsack is freely stretched by rotating disk and expansion strip (band), have simple in structure, advantage of low manufacturing cost.

[specific embodiment]

Among the figure:

1: inclusion;

11: loam cake; 12: waist; 13: base;

2: braces;

3: rotating disk;

31: handle; 32: navigation button; 33: rotary column; 34: fixture;

4: expansion strip (band).

See also Fig. 1 and Fig. 2, Fig. 1 and Fig. 2 are respectively three-dimensional structure diagram and the side view of waist of the present utility model when tightening state.Scalable knapsack has inclusion 1 and braces 2, wherein, inclusion 1 is again by loam cake 11, waist 12 connects to form with base 13, base is connected with braces 2, offer a strip opening (figure does not show) in the base bottom, opening is by slide fastener or easy-to-drawly buckle stitching, by this opening, can put into the thing that needs are placed in the knapsack, at the top of loam cake 11 rotating disk 3 is installed, radially evenly offer some guide grooves at last exterior surface, can be three～ten, illustrated embodiment is six guide grooves, is embedded with a flexible expansion strip (band) in each guide groove, one end of every expansion strip (band) is connected on the rotating disk 3, and the other end is fastened on the base 13.Rotate rotating disk 3, make expansion strip (band) 4 pack up or decontrol, and waist 12 is in tighten or releasing orientation; When waist 12 is in when tightening state, waist 12 is folding, makes base 13 as much as possible near loam cake 11; Handle 31 is installed on rotating disk 3, this handle 31 can make things convenient for the rotation of rotating disk 3, a positioner is installed on handle 31, this positioner is a navigation button 32, and under the normal condition, rotating disk 3 is in the lock state, by pressing navigation button 32, can rotate rotating disk 3, drive expansion strip (band) 4 and make waist 12 be in different states, reach the purpose of flexible knapsack.

See also Fig. 3, Fig. 4 and Fig. 5.Along with the rotation of rotating disk 3, the expansion strip (band) 4 that tightens up is decontroled gradually, at this moment, base is gradually away from loam cake, and waist 12 unclamps gradually to full-gear, and when the amplitude of unclamping was maximum, it is maximum that the content volume of knapsack reaches.

See also Fig. 6, Fig. 6 is the structure chart of a kind of embodiment of this practical turntable.As shown in the figure, rotating disk 3 has a handle 31 and rotary column 33, navigation button 32 is installed on handle 31, several fixedly fixtures 34 of expansion strip (band) are installed equably in the bottom of rotary column 33, the number of this fixture 34 is general corresponding with the bar number of expansion strip (band).

Although the utility model has been done detailed explanation and has been quoted embodiment as proof; but for those of ordinary skill in the art; according to above-mentioned explanation, various replacement schemes, modification and the change that obviously can make all should be included within the protection domain of claim.
