DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a backpack. More specifically, the present invention relates to a backpack for storing a notebook computer having a considerable weight, such as a so-called day bag whose material is flexible and lightweight.

[0002]

2. Description of the Related Art With the spread of personal computers in recent years, it has become common for thin notebook computers to be carried in a bag. Often seen as a bag carrying a notebook computer is a handbag-type hard case bag. Because the bag is a hard case, it is possible to protect the notebook computer from impact.

[0003]

Since a notebook personal computer is thin and has a considerable weight, when carrying the personal computer, a conventional hard case carrying bag may cause a shock which is a fatal injury to precision equipment. It is effective to protect from.
However, since this bag itself has a considerable weight, if the weight of the notebook computer is further added to the bag, a considerable pressure is applied to the hand of the person carrying the bag. In addition, carrying one hand is dangerous because you may accidentally drop your bag when it hits a person or object. In order to solve such a problem, it is conceivable to use a backpack such as a so-called day bag which has a small overall weight and can be carried in a backpacking manner. However, since this kind of backpack is made of a flexible material, it is difficult for a thin and heavy laptop to stabilize in the bag, and it can easily fall down in the front-rear direction and become unstable. Will be stored.
Therefore, the swing of the notebook personal computer in the bag portion is inevitable, and it is inevitable that the result will cause damage. Especially when the laptop is tilted forward and retracted, the laptop will not be able to handle a large shock when the bag is hit against a hard object such as a building wall or door. And result in critical damage that renders it unusable. In addition, when the notebook computer easily swings in the bag portion, the tension at the upper end of the backpack becomes stronger or weaker every time the notebook PC is swung, and it is uncomfortable. In addition, when the upper part of the notebook computer tilts in the opposite direction to the back due to the rocking, and it stabilizes in that state, the base of the backpack is bent back in the tilt direction of the notebook computer, and the shoulder belt is shouldered. Because I strongly press it, I feel uncomfortable in my back.

[0004] These problems are solved by the fact that the notebook personal computer can always maintain a standing state on the back of the carrying bag, but in the case of a student who is a user of the notebook personal computer, a notebook other than the notebook personal computer is used. Since books, writing instruments and writing utensils are indispensable for commuting to school, they can be stowed together to stabilize the storage state so that the notebook computer does not tilt.
However, these storage amounts are not always constant, which is troublesome. Also, when you take out a book, you might end up dropping your laptop. Also, in the case of working adults, for example, clothes changed during a business trip can be stored together with a laptop computer, but similarly, storage items are put in and out of bags, so the storage amount is not constant, so laptop computers It cannot always be stored in a standing state.

According to the present invention, a notebook personal computer is always stored in a stable state, and at the same time, it is possible to obtain an extremely stable backing state for protecting a precision instrument from a shock which is a weak point of the precision instrument and for securely carrying the precision instrument. It is an object of the present invention to provide a carrying bag that can be used.

In other words, a pair of shoulder belts is attached to the outer surface with the back as the boundary, and a PC storage unit is attached to the opposite inner surface. Therefore,
The laptop inside the PC compartment will be in close contact with the inside of the back, so the thickness of the back of the bag and the thickness of the laptop will be added to the back of the bag. The thickness of the back. In addition, a portion of this thicker thickness comes from laptops, so the back is extremely sturdy.

In such a bag, the notebook computer does not lean forward in the bag, and can always be kept in a standing state, so that the notebook computer does not swing during carrying. And when you carry your laptop, you can carry it with peace of mind because the laptop is close to your back and has a sense of unity. In addition, since injury is substantially avoided, it is possible to carry with confidence. Furthermore, since the upper part of the notebook computer does not tilt forward, the base of the shoulder belt does not bend, and the shoulders are not strongly pressed.

The chain double-dashed line indicates a state in which the hand is attached to the backpack. FIG. 2 is a perspective view of the back side of the backpack, FIG. 3 is a perspective view showing a state in which the first bag portion is opened, and FIG.
FIG. 5 is a schematic sectional view taken along the line II of FIG. 5, FIG. 5 is a sectional view of the first bag portion, FIG. 6 is a schematic sectional view taken along the line II-II of FIG. 1, and FIG. FIG. 8 is an enlarged view, FIG. 8 is a sectional view showing a stored state of the notebook personal computer, and FIG. 9 is a view of another embodiment.

As shown in FIGS. 1 to 5, the back bag comprises a main bag 1, ie, a first bag portion 1a and a second bag portion 1b provided in front of the first bag portion 1a. And The first bag portion 1a has a rear surface 2, a body gore 3 having one peripheral edge on the periphery of the rear surface 2, and a second peripheral portion of the body gore 3 facing the rear surface. Of the first bag 1a (or the partition 4a of the first bag 1a and the second bag 1b). Back surface 2 of first bag 1a
As shown in FIG. 8, a base end of a backpack belt 5 is attached to an intersection between the back surface 2 and the body gore 3. The back surface 2 has an outer fabric 6 and an inner fabric 7, and a cushion body 8 having substantially the same size as the back surface 2 and a thickness of about 3 to 8 mm is interposed therebetween. A cushion body 9 having a substantially U-shape and a thickness of about 10 to 15 mm is provided on a lower peripheral edge of an upper side surface of the outer cloth 6, and the cushion body 9 is covered with a covering material 24. In addition, the front end of the backpack belt 5 has a connecting tool 11 for connecting to a length adjusting tool 10 provided near the lower part of the backpack.

The first bag section 1a has a personal computer storage section 12 therein. Specifically, a personal computer storage section 12 is provided directly on the lower surface of the inner cloth 7 on the back surface 2. The back surface 2 of the bag 1 also serves as the back surface of the personal computer storage unit 12, and the personal computer storage unit 12 includes the back surface 2, the front surface unit 13, the side gores 14, and the bottom gores 15. The back surface 2 has the cushion body 8 as described above, but the front surface portion 13, the side gore 14, and the bottom gore 15 also have the same cushion body 16.
Each of these cushion bodies 16 is interposed between two thin fabrics. As shown in FIGS. 4 and 5, a gap is formed between the personal computer housing 12 and the body gore 3. More specifically, the side gores 14, 14 meet the inner cloth 7, but are located inside the back side edge, and a gap is formed between the side gores 14 and 14. The edge of the bottom gore 15 overlaps with the edge of the body gore 3 and the bottom edge of the back face 2 and the bottom edge of the body gore 3 at the same time. As a result, a thicker, harder attachment part is obtained. Therefore, the bottom surface (bottom gore) of the personal computer housing 12 is located slightly above the bottom surface of the body gore 3. In addition, bottom gore 15 and body gore 3
Some gaps are also formed between the bottom surfaces of. The upper end of the opening 17 of the personal computer housing 12 is separated from the upper part of the body gore 3 so that the upper part of the body gore 3 does not become an obstacle for taking out the notebook computer. A lid 18 adjacent to the opening 17 is attached to the inner cloth 7.
Further, the width of the side gore 14 of the personal computer housing 12 is shorter than the width of the body gore 3 of the first bag portion 1a. Therefore, different amounts of gaps 19 are formed around the personal computer storage portion 12 between the first bag portion 1a and the personal computer storage portion 12. Note that a larger gap between the bottom gore 15 of the personal computer housing 12 and the bottom of the body gore 3 is more effective in further protecting the notebook personal computer from impact. To the appropriate part of the inner cloth 7 and the bottom gore 1
A reliable gap may be formed between 5 and the body gore 3.

As each of the cushions 8, 9 and 16, it is preferable to use a foam, particularly a foam having adhesive elasticity. As the foam having adhesive elasticity, "Temperfiom", a type T of shock absorbing resin foam manufactured and sold by Dynamic Systems, Inc. of the United States, is used.
In addition to -47, T-41, T-38, and T-36, those having the same level of performance as those commercially available under the trade name of memory foam are particularly preferable. These have high absorption and diffusion performance of shock and vibration, high air permeability and heat absorption, high moisture absorption and moisture permeability, so they fit on your back, but when you sweat on your back It has the effect of preventing stickiness and dirt due to sweat. In addition, since it is lightweight (specific gravity: about 0.1), there is an advantage that the burden on the user is light.

The foam sheet having adhesive elasticity is as follows:
Usually, it is preferable to adjust the shock absorbing action by stacking 2 to 5 sheets having a thickness of about 2 to 5 mm, but the thickness is 5 to 10 m.
m, or only one sheet of about 2 to 5 mm may be used. Since it is sticky,
The stacked foam sheets do not deviate from each other. Also,
Only a foam sheet having adhesive elasticity may be laminated, or may be laminated with a thin ordinary foam sheet (cushion sheet).

FIGS. 1 and 7 show the front of the first bag 1a.
, A second bag portion 1b is provided. Each bag portion is separated by a partition portion 4a made of a relatively strong nylon thin cloth which also serves as the lid portion 4 of the first bag portion. The capacity of the second bag portion 1b may be larger than that of the first bag portion. In the drawing, reference numeral 20 denotes the personal computer housing 12.
Thin fabric 21 with cushion body 16 of
Is an opening / closing fastener attached to the body gore 3, 22 is a hanging portion, 23 is an intersection of the back surface 2 and the body gore 3, 24 is a covering material of the cushion body 9, 25 is a gore of the second bag portion 1b, 26
Is an opening / closing fastener provided on the gore 25, and 27 is a sub-bag portion provided below the second bag portion 1b.

Next, the state of use will be described with reference to FIG. The PC storage unit 12 has a cushion body 16 on each surface except the opening 17.
However, the elastic action of the cushion body 16 is as follows.
Since the notebook personal computer can be brought into close contact with the personal computer storage unit 12 and also with the back surface 2, the back surface 2 of the book bag 1 of the backpack can be held by the close contact of the notebook personal computer A. It has a strong back that is not available. Also, the back surface 2 does not bend. However, since the elasticity of the U-shaped cushion body 9 can gently come into contact with the curved surface of the back, even if the back surface 2 is strong, the feeling of carrying is good. Therefore, even if a moderate amount of heavy goods are stored in the second bag portion 1b, the back surface 2 is prevented from being bent and pulled in the direction of the second bag portion. Is prevented from being forcibly pulled in the direction of, so that a sense of unity with the backpack can be obtained on the back, and the backpack can be carried in a stable backpack state.

Further, as shown in FIG. 6, the personal computer storage section 12 has a cushion body 16. Therefore, FIG.
When a laptop computer with a two-dot chain line larger than the width W and the thickness D inside the personal computer storage unit 12 shown in FIG. 5 is stored in the personal computer storage unit 12, as shown in FIG.
The cushion body 16 is pulled in the direction of the arrow. The notebook computer A is stored in close contact with the back surface 2 and the personal computer storage section 12. Therefore, the swing of the notebook personal computer when carried is prevented to the utmost. Further, as shown in FIG. 4 or FIG. 7, since a gap 19 is formed around the personal computer storage section 12, even if the carrying bag is placed on the floor or a desk in either the portrait or landscape orientation, the notebook type can be used. The impact is hardly transmitted to the personal computer A. Further, the shock is diffused by the cushion body 16, so that the notebook computer A is reliably protected from the frequent shocks when carrying. In addition, the weight of the conventional hard case-type bag is eliminated, and it is possible to carry it lightly and securely with a lightweight bag.

In another embodiment, not shown, the personal computer storage portion is in the form of a personal computer storage bag and can be completely separated from the first bag portion. The mounting position in the case of the personal computer storage bag is also inside the outer periphery of the back surface 2 as in the above-described embodiment, and the mounting method is detachably provided by a strong connecting tool such as a hook, a fastener, and a hook-and-loop fastener. Therefore, the notebook computer can be protected from impact. In addition, the notebook computer can be easily and quickly taken out by simply removing the personal computer storage bag from the first bag portion. After the storage bag is once removed from the first bag portion, it can be taken to the desk as it is.
And to take out the laptop from the storage bag,
Since it is not complicated, it can be taken out without fail.

In still another embodiment, as shown by a two-dot chain line in FIG. Normally, a notebook PC is carried in a backpack. However, even when used as a handbag in a crowded train or the like, there is a gap between the PC storage unit 12 and the body gore 3. Even if a shock is applied, the shock to the notebook computer is prevented.
