Description

[Detailed description of the invention] This invention relates to an improvement of a rucksack,
A waterproof cover is installed inside the cover provided on the top of the rucksack body, and this can be stored and taken out whenever necessary to cover the outer surface of the rucksack body, preventing rainwater from falling directly onto the rucksack body. The purpose is to obtain a rucksack of extremely practical value that can prevent such problems.

Traditionally, backpacks especially for mountain climbing have been designed to protect against unexpected rain,
Taking into consideration mountain conditions where the weather conditions are extremely variable, such as blizzards and dense fog, we use fabrics made of thick cotton cloth or synthetic fibers such as polyester and nylon that are water resistant, moisture resistant, and have excellent impact resistance. The material used is made from waterproof fabric.

However, even though these rucksacks are waterproofed as mentioned above, there are small gaps between the opening and closing part of the rucksack body and its lid, or the various pockets provided in each part and the lid that covers them. This may allow rainwater etc. to enter and wet the contents, but it is still not completely satisfactory in terms of achieving a complete waterproofing effect.

Therefore, even when mountaineers encounter unexpected rain, they often leave their backpacks exposed to the rain, concentrating only on protecting themselves, allowing moisture to enter through the small gaps mentioned above. They were often unaware that moisture had seeped into the contents.

In order to prevent such defects, some backpacks are equipped with a storage section in a part 9 of the backpack body, such as near the top or the lower end of the back, for storing a waterproof hood that covers the backpack body.

However, in all of these types of backpacks, the storage section is formed directly into a part of the main body of the backpack, so when the contents are stuffed into the main body of the backpack, the contents will be stored inside the backpack. The storage area for the hood, which is provided between the inner and outer covers of the sack, is strongly compressed and the allowable space is significantly narrowed, making it difficult to fold and store the hood and making it difficult to take it out in the event of unexpected rain. Moreover, if the hood is forcibly pushed in for storage, the fabric is likely to be damaged, significantly shortening its useful life.

In addition, the external shape of these rucksacks changes depending on the size and capacity of the items they store, and especially those of the type where the storage opening provided at the top can be squeezed with a string etc., this part tends to deform, and the hood When the hood is covered, a gap is created between the hood and the main body of the rucksack, causing wrinkles, and rainwater or the like accumulates in this area.

The present invention overcomes the deficiencies of the conventional products and provides a backpack that fully satisfies the user.

That is, the present invention comprises a tsuyutsukusak main body A, the tsuyutsukusack main body, a thin plate-like covering C1 having an expanse that covers the top of the tsuyutsukusack main body A, and the tsuyutsukusack main body A.
A storage part 2 having a storage opening 1 that can be opened and closed in a series on the outer surface of the covering body C is provided with the outer cover 4 of the covering body C. It is formed between the inner jacket 5, a series 3 of the covers B is attached inside the storage part 2, and the covers B are formed in the storage part 2 so that they can be stored and taken out.

The above-mentioned present invention will be explained according to an embodiment shown in the drawings. Figures 1 to 3 show that a storage part 2 is formed between an outer cover 4 and an inner cover 5 of a cover C that covers the opening/closing part of the bag body A. A storage opening 1 equipped with a latch 6 such as a slide fastener is provided in the storage part 2, and a cover B is attached to a part of the inside of the storage part 2. This figure shows the cover B stored in the storage part 2 of the bag main body A with the attachment part as the axis.

In Figures 2 to 3, the cover B is taken out from the storage section 2, and the cover B is covered with the bag body A.
The cover B is completely attached to the bag main body A by tightening with a tightening string 8 inserted through the peripheral edge 7 of the bag.

Therefore, in the present invention, since the storage section 2 is provided in the plate-shaped cover C connected to the top of the storage sack main body A, the storage section 2 can be used regardless of the shape or size of the contents packed in the storage sack main body A. Since the cover 2 can always maintain a space in which the cover B can be folded and stored, it can be taken out and stored very easily, and the cover C is formed in a plate shape to cover the top of the bag body A. When the covering body A is covered with the cover B, the cover B and the covering body B come into close contact with each other, and the cover B
It is possible to create tension on the surface and minimize the adhesion of rainwater, etc.

Furthermore, the user can easily open and close the storage opening 1 and take out the cover B from the storage opening 1 and cover the backpack body A with the user wearing the backpack on his/her back.

Therefore, even if unexpected rain occurs, the installation work can be done quickly.

The above-mentioned cover B is made of waterproof fabric made of synthetic fibers such as nylon, vinyl, polyester, and acrylic, or film-like or sheet-like materials such as nylon and vinylon, or woven fabrics of natural or synthetic fibers such as nylon and vinyl. A desired cover B can be obtained by using a fabric coated with a synthetic resin film such as the following.

Furthermore, as a means for attaching the cover B to the backpack body A, the tightening cord 8 inserted through the periphery 7 of the cover B may be made of any elastic material such as a rubber cord or the like. If you use a stretchable one, it will be easier to attach it to the main body of the Tsuyutsukusack.

Further, it is desirable that the inner cover 4 and the outer cover 5 of the cover C forming the storage portion 2 are made of waterproof fabric.

Further, the latching tool 6 attached to the storage opening 1 of the storage portion 2 may be any one such as a slide fastener or a snap.

Figure 3 shows a retaining device 9 such as a hook on a chain 3 of the cover B.
The figure shows a case in which the cover B is attached to the housing section 2 and can be detached from the storage section 2 at will.

If the cover B is made detachable in this way, it is convenient to take out only the cover B and dry it.

Of course, it is also optional to use a retainer such as a snap such as a hook or a velvet fastener for the aforementioned retainer.

As mentioned above, this invention can be stored in a rucksack at all times to deal with unexpected rain or snowstorms, and is suitable for mountain climbing.

This is an extremely practical idea that can be applied to all types of fishing equipment.
