DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag suitable for carrying an electronic device such as a notebook computer or a precision instrument such as a measuring instrument which is not sensitive to vibration or impact.

[0002]

2. Description of the Related Art Conventionally, in order to carry a portable electronic device such as a notebook personal computer, a bag formed by sewing a sheet such as a canvas, or a rigid material such as plastic or light metal is formed to conform to the shape of the device. A hard case or the like in which a storage section is formed has been used.

[0003] In the above-described bag, since the impact from the outside or the vibration during carrying is directly applied to the housed device through a flexible sheet, not only the housed device and the like are easily damaged, but also the bag is housed. Not only does the device move inside the bag and collides with other items, causing damage to the device itself and other items, but also if the stored device is a laptop computer with a certain weight, the There is a problem that the weight is biased or the center of gravity moves, making it difficult to hold.

[0004] The hard case has the advantage of being resistant to external shocks and is used for transporting precision machines other than notebook computers. However, since the internal space is secured, the hard case is stored. Since it is easy for the moving device to move inside, there is a problem that the device itself or other storage items may be damaged by hitting the inner wall of the hard case or other storage items.

[0005] In order to avoid such a problem, a partition can be provided according to the shape of a device or an article to be housed in the hard case, but not only tends to be heavy or large in size but also large. It is necessary to prepare a dedicated hard case according to the shape of the device to be housed, so that other problems such as an increase in cost arise.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a bag which can be manufactured at a relatively low cost by sewing a cloth such as a canvas or a sheet of a synthetic leather or a natural leather. It is an object of the present invention to obtain a bag capable of protecting the bag from external shocks and vibrations.

Further, when the bag is placed on the floor or a desk, an impact is applied to the bottom of the bag, and the impact is indirectly applied to the equipment stored therein. The purpose is to reduce the impact when placing.

[0008]

According to a first aspect of the present invention, there is provided a bag according to the present invention, wherein a stretchable sheet HS having elasticity is provided in the body of the bag B in a hammock shape.

As the "stretchable sheet having elasticity" in the present invention, for example, a sheet formed by foaming chloroprene rubber and forming the sheet can be used. Further, “hammock-like” means that even when an article is placed on the stretchable sheet HS suspended in the main body of the bag B, the lowest portion HE of the stretchable sheet HS does not contact the bottom surface in the bag B. It is to say.

According to the structure of the first aspect, the article M placed on the stretchable sheet HS is suspended by the stretchable sheet, and the shock and vibration in the vertical direction are reduced by the stretchability of the stretchable sheet. Absorbed. Further, by making the elastic sheet HS thick, it is possible to protect the thick elastic sheet HS by absorbing shocks and vibrations not only from above and below but also from the side.

[0011] The bag according to the second aspect of the present invention comprises one outer surface Wa and the other outer surface W of the bag B.
In addition, bar-shaped buffer members Ca and Cz having a thickness such that the bottom surface does not touch the ground even when an article is stored and placed under the bag B are arranged at opposite edges of the bottom surface BE between the z. I do.

A sponge,
In addition to a foam such as styrene foam and foamed polyethylene, an air tube in which air is sealed in an airtight thin plastic bag may be used.

The thickness of the bag is such that it does not touch the ground even when articles are stored in the bag. If the bottom surface of the bag B is soft, a relatively thick cushioning member will be used. If the bottom surface BE is relatively stiff, for example, reinforced with a plastic plate, it can be made thinner as long as required cushioning can be maintained.
