Abstract

(57) [Summary] [Purpose] The user's back is comfortable when in use,
Further, the present invention provides a school bag which is capable of preventing stuffiness of a storage space for contents. [Structure] On a back plate that contacts the user's back, a large number of through holes that connect the space on the back side of the user to the back plate and the accommodation space for contents are scattered.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bag used by a person carrying a backpack such as a school bag or a backpack (in the present description, these are collectively referred to as a school bag).

[0002]

[Prior Art]

 When a conventional school bag is used while being carried on its back, the back plate of the school bag separates the space on the back side of the user who carries the backpack from the accommodation space inside the school bag.

[0003]

[Problems to be solved by the device]

 In this conventional school bag, when the user runs up and sweats on the back, the back plate causes the back side of the user to retain hot air and moisture, which causes the user to feel uncomfortable. there were. In addition, there is a problem in that the material forming the school bag is easily odorized inside the school bag, and the stored items are odorized.

The present invention has been made in order to solve the above-mentioned problems (technical problems) of the prior art. When the user sweats on the back, the evaporation can be promoted, and the accommodation space can be improved. The purpose of the present invention is to provide a land cell that can promote the replacement of the air in and keep the inside clean.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the school bag according to the present invention has a large number of through-holes, which communicate with the accommodation space inside the school bag, provided in the back plate of the school bag facing the back of a person.

[0006]

[Action]

 If the back plate repeatedly contacts and separates from the user's back while the user carries the backpack, the space on the user's back side and the accommodation space are separated through the many through holes provided in the back plate. Forced ventilation is performed between. This forced ventilation promotes the evaporation of the sweat of the user on the back side of the user and the replacement of the air in the accommodation space side.

【Example】

 Hereinafter, drawings showing examples of the present application will be described. Reference numeral 1 indicates a school bag. 2 is its main body, and 3 is an accommodation space, which is open at the top as is well known. 4 is a lid piece, 5 is a latch, and 6 is a backpack band. Next, 8 indicates a back plate of the main body 2. Reference numeral 9 denotes a back rest surface of the back plate 8, the central portion 10 of which is formed in a concave shape, while the left and right side portions 11, 11 and the lower portion 12 are formed in a bulge shape, which is stable on the user's back. It is arranged to follow. Reference numeral 13 denotes a through hole provided in the back plate 8, and a large number of them are scattered in the area shown by the reference numeral 14 in FIG. As is apparent from FIG. 3, this through hole 13 is formed in a state where the outside of the back plate 8 on the back contact surface 9 side and the accommodation space 3 inside the main body 2 communicate with each other.

Next, the structure of the back plate 8 will be described with reference to FIG. Reference numeral 15 is a base material, which is formed to have a size over the entire area of the back plate 8 and is formed of a hard plate-shaped body. Reference numeral 16 is a covering member, which covers the entire area of the backing surface 9 side of the base material 15, and is formed of a soft sheet-like material having a soft feel. The left and right side parts 11, 11 and the lower part 12 have a flexible cushioning material interposed between the base material 15 and the covering member 16 so as to softly contact the user's back. I am doing it. Reference numeral 17 denotes an activated carbon sheet used only at the location of the recessed central portion 10, and 18 denotes a covering member for covering the activated carbon sheet 17, which is formed of a soft synthetic resin sheet material, and the periphery thereof is a base. It is fixed to the material 15 by sewing means. Adhesive means may be used.

Next, a usage state of the school bag 1 having the above configuration will be described. In the storage space 3, textbooks, notebooks and other school supplies are stored in a familiar manner. Then, carry the shoulder strap 6 and carry it on your back.

In the above-described use state, the back plate 8 of the school bag 1 is pressed against the back 20 of the user due to movement of the body as the user walks or runs, and Repeatedly becoming separated. As a result of this repetition, forced ventilation is performed through the through hole 13 between the space on the back 20 side of the user and the accommodation space 3 by the pump action. That is, when the back plate 8 approaches the user's back 20, the air in the space on the back side is compressed by the back 20 and the back plate 8 to increase its pressure, so that the air there is accommodated through the through hole 13. It flows into 3. On the contrary, when the back plate 8 separates from the back 20, the pressure in the space between the two is reduced, so that the air in the accommodation space 3 flows through the through hole 13 to the space on the back side. In this case, in particular, as is apparent from FIG. 4, the left and right sides of the central portion 10 in which the through hole 13 is provided are surrounded by bulging side portions 11, 11, and the lower side of the central portion 10 is also bulged. Since it is surrounded by the protruding lower part 12, the pumping action is performed with high efficiency, and the forced ventilation through the through hole 13 is performed more reliably. As a result of the forced ventilation as described above, the back 20 of the user is kept in a well-ventilated state. Further, the air inside the accommodation space 3 is forcedly ventilated through the through hole 13 to pass through the through hole 13, the upper opening portion 21 of the main body 2 and the space 22 between the main body 2 and the lid piece 4 so as to be exposed to the outside air. Good replacement with air.

[0011]

[Effect of the device]

 As described above, in the present invention, when the user walks or runs while carrying the back 20 on his back, the back plate 8 may contact the back 20 with the movement of the user's body. By repeatedly separating and separating, the space between the user's back side with respect to the back plate 8 and the accommodation space 3 in the main body 2 is forcedly ventilated through the through hole 13 by the pumping action accompanying the repeated contact and separation. There is a feature that can be done. This has the effect of keeping the breathability of the user's back at all times, and has the effect of bundling a comfortable condition of use. Moreover, in the accommodation space 3 in the main body 2, the air there is forced. Since it can be replaced, it has an effect of eliminating stuffiness inside the accommodation space 3.
