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...

AI Technical Summary

Benefits of technology

The present invention is a backpack with a tube-type shoulder belt that can prevent the backpack from slipping down and moving sideways, reducing the burden on the wearer's waist and relieving the heavy feeling of the backpack. This reduces fatigue and spinal pain caused by carrying the backpack for a long time. The backpack corrects the wearer's posture and provides better support, which prevents spinal issues and fatigue.

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 for tightening the wearer's chest part to fix the backpack to the shoulders.

However, because the shoulder pads are in a simple structure that wrapping paper is covered and sewed on an urethane foam or a sponge, which is fit on the shoulder belts, the shoulder pads can just relieve pain or impact on the shoulders but cannot disperse the weight applied to the waist and shoulders when the wearer carries the backpack on the shoulders, and hence, the conventional methods cannot solve the above-mentioned problems.

However, the prior arts cannot reduce a burden applied to the wearer's waist because the backpack is not fixed to the wearer's shoulders, and hence, have a problem in that the backpacks may cause spondylopathy or fatigue because the backpack slips down from the wearer's shoulders due to the weight of the backpack or moves sideways.

Therefore, the backpacks according to the prior arts can relieve only the pain applied to the top of the shoulder of the wearer where the shoulder protector touches but cannot reduce the burden on the wearer's waist, and hence, cannot solve the problem caused by pressure applied to the wearer's spine or clavicle.
