Abstract

(57) [Summary] [Purpose] To provide a backpack bag having a novel backrest part which is excellent in cushioning property as well as breathability and does not cause discomfort even when sweating. [Composition] Outer mesh 1 in order from the side that touches the back,
It is characterized in that it comprises a backrest portion 5 having a structure in which a lock material 2, a core material 3 and a lining 4 are superposed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a backpack bag such as a rucksack, and more particularly to an improvement of a backrest portion that contacts the back.

[0002]

[Prior art]

 The back part of the conventional backpack bag uses elastic foam material such as urethane as the core material.

[0003]

[Problems to be solved by the device]

 The back part of the conventional backpack bag, which uses the elastic foam core as described above, has cushioning properties but insufficient breathability, and the sweat does not dry easily when sweating on the back. I felt sick and uncomfortable. Therefore, an object of the present invention is to provide a backpack bag which has not only cushioning properties, but also excellent breathability and has a novel backrest portion that does not cause discomfort even when sweating.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the backpack bag of the present invention comprises a backrest part having a structure in which a mesh-shaped outer material 1, a locking material 2, a core material 3, and a lining 4 are superposed in this order from the side that contacts the back. It is characterized by that. Here, the lock material 2 refers to a material in which animal or plant fibers or synthetic fibers are curled into a spring shape and hardened into a mat shape with a binder.

[0005]

[Action]

 The breathability is remarkably improved by making the outer material 1 into a mesh shape and providing the lock member 2. The lock material 2 is of course also good in cushioning properties.

[0006]

Embodiment An embodiment of the present invention will be described below with reference to the drawings. First, FIG. 1 shows the entire backpack as an example of a backpack bag. In the figure, the position indicated by reference numeral 5 is the backrest part. The cross-sectional structure of the backrest 5 is as shown in Fig. 2. From the side that touches the back, the cloth-made surface material 1 in the order of cloth, the synthetic fibers are curled in the shape of a spring, and the mat is fixed with a binder. In addition, a lock material 2, a core material 3 made of elastic foam material, and a lining 4 made of waterproof cloth are laminated. The core material 3 has a cushioning property together with the lock material 2, and the backrest portion 5 has a waist.

[0007]

[Effect of device]

 The backpack bag of the present invention is as described above, and includes the backrest portion 5 having a structure in which the mesh-shaped outer material 1, the lock material 2, the core material 3, and the lining 4 are stacked in order from the side that contacts the back. Not only the cushioning property, but also the breathability is remarkably improved, and even if you sweat on your back, the sweat dries immediately and you will not feel uncomfortable, and the usability will be greatly improved.
