Backpack having a tube-type shoulder belt

Abstract

The present invention relates to a backpack comprising a shoulder belt having two ring-shaped tubes provided with respective air-injection portions so as to enable a user to inject air into the tubes to inflate the shoulder belt and to thus enable the backpack to tightly contact a shoulder of a wearer. Thus, the backpack is prevented from slipping down from the shoulder of the wearer or from moving sideways, thereby protecting the waist of the wearer from being burdened to thus prevent spondylopathy and fatigue, and rendering user activity convenient. The shoulder belt of the backpack of the present invention has the ring-shaped tubes provided with respective air injection portions. In addition, two tubes of the shoulder belt are interconnected via a pipe, the length of each tube is extended toward the body of the backpack such that the length of each tube is the same as that of the body of the backpack, and the tubes are coupled to a back of the backpack. Preferably, the shoulder belt may be wrapped in fabric or the like so as to be protected and connected to the body of the backpack, or the shoulder belt may be made of fabric or the like, and the upper portions thereof may have spaces for accommodating said tubes, respectively.

Description

TECHNICAL FIELD[0001]The present invention relates to a backpack including shoulder belts respectively having hook-shaped (∩-shaped) tubes. More particularly, the present invention relates to a backpack which enables a wearer to inject air into the tubes to inflate the tubes into the ∩-shaped form and to thus enable the backpack to tightly contact the wearer's shoulders despite of weight of the backpack, so that the backpack is prevented from slipping from the wearer's shoulders or from moving sideways and the wearer can feel less pressure of the backpack to the wearer's shoulders.BACKGROUND ART[0002]In general, because a backpack that a student mainly uses instead of a school bag or uses for traveling or hiking contains heavy things such as books or articles therein, the weight of the heavy backpack is transferred to the a wearer's body as it is, so that the wearer feels too much pressure.[0003]Particularly, because the heavy backpack imposes a heavy burden on the wearer's waist an...

Benefits of technology

[0016]The backpack having the tube-type shoulder belt according to the present invention has hooks formed by air injected into the tubes located on the upper portions of the shoulder straps for suspending the backpack on the wearer's shoulders so as to prevent the backpack not from slipping down from the wearer's shoulders and moving sideways by fixing and supporting the backpack on the wear

Problems solved by technology

In general, because a backpack that a student mainly uses instead of a school bag or uses for traveling or hiking contains heavy things such as books or articles therein, the weight of the heavy backpack is transferred to the a wearer's body as it is, so that the wearer feels too much pressure.

Particularly, because the heavy backpack imposes a heavy burden on the wearer's waist and shoulders, it has a bad effect on the wearer's spine and increases fatigue, and especially, threatens teenage students' health.

Moreover, because the wearer who carries the bag on the wearer's shoulders cannot walk in a correct posture due to a severe pressure and pain on the shoulders and walks in an awkward posture, and hence, in the case of teenagers who carry the bags on their shoulders every day, they have several problems in that their spines are crooked or distorted in the process of their growth and in that they may feel pains on the waist, shoulders, or neck.

However, such a method is just a temporary expedient and, actually, it is not easy to relieve the strain or pressure on the waist and shoulders, and hence, some of the backpacks respectively have a strap
