Description

A kind of knapsack

The utility model relates to for the knapsack of people's back of the body at the shoulder belongings, belongs to the daily necessities field.

It is very frequent contacting with knapsack in the human life; carry the knapsack that the stationery books are used when for example going to class; go shopping, out on tours all uses knapsack or the like through regular meeting; only, do not have the space between general known knapsack back and user's the back, promptly the knapsack back is directly to paste the back of touching in the user; like this in hot summer; owing to do not have the space between human body back and the knapsack, just can make the sultry perspiration in back, do not feel well.

Because the shortcoming of above-mentioned traditional backpacks, this creator is through long-time research and innovation, and development and Design goes out a kind of knapsack finally, this knapsack be in use and human body back between have the space, can make circulation of air, unlikely soaked with sweat, comfortable attractive in appearance.

The purpose of this utility model is achieved in that

A kind of knapsack, comprise inclusion and braces, it is characterized in that having additional an offset plate in inboard, inclusion back, this offset plate and inclusion back side cloth similar shape, offset plate middle part one side is sunk and is formed microscler depressed part, and depressed part forms jut in another side thus, and inclusion back side cloth and this offset plate are tightened combination, depressed part is outside inclusion, and jut is in inclusion.

Described depressed part is to be by the edge to the gradually dark arc sag structure in middle part, and offset plate integral body also be one with arc-shaped recess portion arc bending in the same way.

This face of offset plate jut be provided with a liner cloth cover in addition and with the outer cloth cover of inclusion with the offset plate overseam in wherein.

This offset plate is that polypropylene (polypropylene) material is made.

Hence one can see that, the utility model utilization sets up one by the molded offset plate of polypropylene thermal on knapsack, and the bounce of borrowing this offset plate, make knapsack face cloth tighten on this offset plate, as the combination of bow chord, borrow the depressed part of arc on the offset plate body and the integral body curved structure of arc in the same way, make in use that human body back and the knapsack back side have a space, promptly inclusion does not contact with the people back except that the shoulder braces basically, can make air space circulation thus, make that the back is unlikely to swelter, comfortable attractive in appearance.

To unitary construction of the present utility model, device, feature and effect thereof further understanding and understanding can be arranged for making, now the utility model be implemented the situation conjunction with figs. and be described in detail as follows.

Brief description of drawings

Fig. 1 is the utility model overall structure schematic diagram.

Fig. 2 is the shape of the offset plate in the utility model after hot-forming.

Fig. 3 is the A-A cutaway view of Fig. 2.

Fig. 4 is the B-B cutaway view of Fig. 2.

Shown in each accompanying drawing, a kind of knapsack of the utility model, comprise inclusion 1 and braces 2, it is characterized in that having additional an offset plate 3 in inboard, inclusion back, this offset plate and inclusion back side cloth similar shape, offset plate middle part one side is sunk and is formed microscler depressed part 31 (referring to Fig. 3), and depressed part forms jut 32 in another side thus, inclusion back side cloth and this offset plate are tightened combination, and depressed part is outside inclusion, and jut is in inclusion.Above-mentioned depressed part 31 is to be by the edge to the gradually dark arc sag structure (seeing also Fig. 4) in middle part, and offset plate integral body also be one with arc-shaped recess portion arc bending in the same way.This face of offset plate jut 32 is provided with a liner cloth cover in addition and with the outer cloth cover of inclusion offset plate is wrapped in wherein, so that the sense of inclusion inner body is stronger.

In sum, the innovative design of the utility model knapsack truly has its practicality with creative, and this structure does not see any publication, so propose utility application.

The above only is a preferred embodiment of the present utility model, when can not with the scope implemented of qualification the utility model.Promptly the equalization of doing according to technical solutions of the utility model generally changes and modifies, in the scope that all should still belong to technical solutions of the utility model and contained.
