Description

  The present invention provides a rucksack that is used daily during schooling, commuting, travel, shopping, etc., with a security function against slips, etc., and is long on a back strap so that one rucksack can be used in three ways. The present invention relates to a multifunctional security rucksack provided with a thickness adjusting mechanism.

In general, a conventional rucksack is provided with an opening for taking in and out at the front or upper part of the bag body, and the opening becomes a blind spot of the user when carried on the back.
In addition, when the contents are frequently taken in and out, the shoulder strap of the rucksack is carried on the arm or one shoulder without carrying it. Furthermore, conventional multi-functional rucksacks have individual strings depending on the application and need to be replaced, or have been used by attaching and detaching hand straps.

Therefore, there are the following problems.
(B) When carrying a rucksack, the opening always becomes the blind spot of the user, so if you forget to close the opening, you will not notice it even if you drop the contents, or the opening is exposed to the outside It was easy to encounter damage such as pickpockets.
(B) When carrying a rucksack without carrying it, the back strap was hung on the arm like a handbag or on one shoulder like a shoulder bag, but the rucksack has a unique shape to carry However, it did not look good as a handbag or a shoulder bag, and it could not be said that it was easy to use. Also, multi-functional bags that can be used as both a carrying bag and a carrying bag require separate work for attaching and detaching individual laces depending on the application, and it takes time, and multiple laces are attached.
The present invention has been made to solve the above problems.

  The rucksack opening is provided only on the back of the bag body that comes in contact with the back when it is carried on the back, and there is no opening or exit on the front of the bag body, and the length of the back strap is adjustable. A mechanism is provided so that it can be used comfortably and safely as a rucksack or shoulder bag when the string is the longest and as a handbag when the string is the shortest. This is a multifunctional security rucksack characterized by the above.

When the bag is carried as a rucksack, an opening for taking in and out the contents is provided only on the back of the bag body that is in contact with the back. In the structure that does not provide any outlets, etc., the opening of the bag body is not exposed to the outside even when used on the back, and since the opening is in contact with the back, It is not easy for the user to take out the contents from the opening without being noticed by the user, and it is possible to prevent damage such as pickling.
Furthermore, since there is no outlet / outlet in the front part of the bag body, the front part can be used as the bottom part. Therefore, when used as a handbag or shoulder bag, the front part of the bag body can completely be the bottom part of the bag body even if the opening located on the back part of the bag body is directed upward. There is no hindrance to taking in and out and carrying around. It can be easily used as a handbag or shoulder bag by simply adjusting the length of the back strap. There is no need to attach or detach individual strings, the bag body always maintains a simple appearance, and the design and fashionability of each bag is high.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

(A) The bag body (1) of the rucksack has a shape as shown in FIGS. 1 and 2, and its back surface (1a), front surface (1b), and side surface (1c) are all side surfaces. ing.
(B) As shown in FIG. 1, the opening (2) for taking in and out the contents is provided only in the back surface (1a), and all the in and out of the front portion (1b) shown in FIG. Do not make a mouth.
(C) The back strap (3) is provided in a flat belt shape so that it can be carried on both shoulders, and has a length adjusting mechanism (4) capable of adjusting the length.
(D) In Example 1, the length adjusting mechanism (4) uses the buckle (4a) and the frame (4b), and one end of the back strap (3) is sewn to the bag body (1). Yes, the other end is first passed through the buckle (4a) and then stitched to the back body (1) via the frame (4b). Thus, the back strap (3) passed through the frame (4b) slides along with the sliding movement of the buckle (4a).
The present invention is configured as described above.
When this is used as a rucksack on the back, the buckle (4a) is slid to adjust the back strap (3) to a longer length, and is carried on the back through each arm as shown in FIG. The length of the back strap (3) is adjusted according to the user's physique and preference.
When carried on the back as shown in FIG. 5, the opening (2) of the bag body (1) is in contact with the back and is not exposed to the outside, and the front surface (1b) is entirely covered. Therefore, it is impossible to take out the contents from the outside. The conventional rucksack is the same, but when the user himself puts in and out the contents of the bag, he takes it down from the back and opens and closes the opening (2).
Further, when the back strap (3) is adjusted to be long, the two back straps (3) are bundled and hung on one shoulder and used as a shoulder bag.
Next, when used as a handbag or a handbag as shown in FIG. 6, the buckle (4a) is slid and the back strap (3) is adjusted to a short length according to preference. When the contents are taken in and out, as shown in FIG. 3, the back part (1a) can be directed upward and the front part (1b) can be placed at the bottom. Even if the front part (1b) is the bottom part, there is no problem in use.
In any application, it can be adjusted without using a separate string or accessory, and the application can be easily changed and used comfortably while maintaining design and fashionability.

  The shape and material of the bag body (1), the back strap (3), and the length adjusting mechanism (4) of the present invention are arbitrary. For example, as shown in Fig. 7, the material of the bag body is made of cotton, the shape is oval, and the back strap is made of only one leather, and the length adjustment mechanism is a belt buckle type. And The bag having the above-described structure can be used as a multifunctional security rucksack because it is possible to carry one shoulder on a shoulder strap and carry it on the back.

  In Example 1 and Example 2 of the present invention, the state of the appearance of the rucksack is described, but as an example of the interior of the bag body (1), as shown in FIG. Or, by providing individual independent spaces and providing lids (fasteners, drawstrings, buttons, double-sided fasteners, etc.) on the opening side of each space, the contents become messy during use in each application Can be minimized. Even if you forget to close the opening (2) and carry it on your back, you can prevent the contents from being scattered outside if you close the lid.
