However, when traveling for a long time using a thick material or a backpack wearing an auxiliary back, there is a problem that the back of the backpack is in close contact with a person's back and is not discharged to the outside even when sweat occurs on the person's back.

The present invention was created to solve the problems inherent in the backpack according to the prior art as described above, an object of the present invention is that the air passage between the back of the backpack and the back of the person while the backpack is in close contact with the person It is to provide a backpack having an air frame for backrest is formed.

Another object of the present invention is to provide a backpack having an air frame for suspenders to reduce the pressure applied to the person from the backpack by the weight of the backpack.

Still another object of the present invention is to provide a backpack having a waist support air frame that can prevent the backpack from sliding down downward in close contact with a waist of a person.

In order to achieve the above object, the present invention, an accommodating part for storing an object, suspenders installed on the upper center and lower ends of the back portion of the accommodating part, and is installed in the lower portion of the backpack so that the backpack is in close contact with the waist In the backpack consisting of a belt, the backrest case of the housing is provided in the vertical direction is provided with a backpack having an air frame so that the air passage is provided in the backrest case.

In order to achieve the other object of the present invention, the present invention provides a backpack having an air frame capable of absorbing the shock so that the impact caused by the weight of the backpack on the suspenders is not applied to the shoulder of the person.

In order to achieve another object of the present invention, the present invention provides a backpack having an air frame that is installed in the waist support portion of the backpack in the horizontal direction so that the backpack is in close contact with the waist so that the backpack does not slide downward.

According to the present invention, the air frame is installed vertically in the backrest case of the storage unit constituting the backpack so that an air passage is formed in the backrest case, and the airframe is installed in the longitudinal direction of the suspenders in the suspenders by the load of the bag. To absorb the shock applied to the belt, the air frame in the longitudinal direction of the belt can be installed to absorb the pressure applied to the waist and abdomen by the belt can improve the wearing feeling of wearing the backpack.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention, the same reference numerals will be used for the same parts throughout the drawings.

1 to 3B, the backpack 100 according to the present invention includes an accommodating part 50 for accommodating an object, and an upper center and a lower end of an upper back case 10 of the accommodating part 50. Suspenders 20 are installed on the shoulder so that the shoulder bag can be carried. The belt 30 is installed under the backpack 100 so that the backpack 100 is in close contact with the waist of the person.

Two air frames 70 are installed in the backrest case 10 of the accommodating part 50 in the longitudinal direction, and an air passage is formed between the back part of the person and the backrest case 10. The air frame 70 is inserted into the fabric 60 constituting the backrest case 10, the air frame 70 is extruded to have a pipe shape in which two to three tubes are joined using polyurethane. To make it. After cutting the pipe-shaped air frame 70 to a predetermined length, both ends are welded and sealed with ultrasonic waves to fill the inside of the pipe with air of a predetermined pressure. When the air frame 70 is inserted into the back support case 10 in the vertical direction at regular intervals, the air frame 70 has a constant thickness, so a passage is formed between the two air frames 70. Air circulates along the passage. Since the two air frames 70 are in close contact with the back of a person, even if a person travels for a long time and sweat occurs on the back, the sweat is quickly discharged to the outside by air circulated through the air passage. In addition, since the two air frames 70 are in close contact with the back portion, there is an effect that the backpack 100 is fixed without shaking from side to side.

In addition, the air frame 70 is inserted into the backrest case 10 also inside the fabric forming the suspenders 20. When the air frame 70 is inserted into the upper portion of the suspenders 20 and the backpack 100 is carried on the shoulder, the air frame 70 is positioned on the shoulder, and thus the impact applied to the shoulder by the weight of the backpack 100. Is absorbed by the airframe 70.

In addition, the air frame 70 inserted into the backrest case 10 is also inserted into the fabric forming the belt 30. When the air frame 70 is inserted into the inner side of the belt 30 and the belt 30 is filled in the waist, the air frame 70 is located at the left and right sides of the waist, and thus the pressure applied to the waist by the belt 30. The air frame 70 is to be absorbed.

In addition, the waist frame 40 of the backpack 100, the air frame 70 is inserted into the backrest case 10 is installed in the horizontal direction. Since the air frame 70 is inserted into the fabric of the waist support 40 in the horizontal direction, the air frame 70 is in close contact with the waist of the person to prevent the backpack 100 from sliding down.

The air frame 70 may be manufactured by extruding into a shape in which three pipes are combined as shown in FIG. 3A, and also extruded by combining two flat pipes as shown in FIG. 3B. The frame 70 can be manufactured.

According to the present invention, in order to form an air passage in the back support case constituting the backpack, the air frame is installed vertically in the back support case, and the air frame is installed in the longitudinal direction of the suspenders in the suspenders by the load of the bag. To absorb the shock applied to the belt, the air frame in the longitudinal direction of the belt can be installed to absorb the pressure applied to the waist and abdomen by the belt can improve the wearing feeling of wearing the backpack.
