Backpack

Abstract

The invention relates to the technical field of daily use articles and specifically relates to a backpack. The backpack includes a bag body and bands connected with the bag body. The bag body includes a back part contacting with a human body. The back part is provided with a spine protecting pad. The spine protecting pad is provided with a ventilating diversion trench in the shape of an S. According to the invention, the backpack with structural improvement has a scientific design of structural features through integrating an ergonomic principle, so that stress can be decomposed scientifically and effectively and the load sense is relieved when a user uses the backpack. At the same time, the heavy load of backpacks for teenagers and children needing to use too heavy backpacks for a long time can be relieved effectively by using the backpack provided by the invention, problems of lower back pain, neck and shoulder muscle pain and the like caused by long term use of heavy backpacks can be avoided and demand for healthy growth of teenagers and children can be met.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a backpack. Background technique [0002] Backpack is a general term for backpacks carried on the shoulders. According to the different uses of the backpack, it is divided into computer backpacks, sports backpacks, leisure backpacks, school bags and rope bags, military backpacks, mountaineering bags and so on. The main features are easy to carry, free hands, light load, good wear resistance, which provides convenience for going out. The back structure of the backpack directly determines the use and grade of the backpack. However, when going out for a long time or climbing mountains, the human body will feel tired. Therefore, it is a research hotspot for those skilled in the art to research a backpack with a reasonable structure and reduce the user's burden. The scientific design of the structural features of the backpack is especially important for school-age childre...

Problems solved by technology

In order to solve the injury caused by the overweight schoolbag to children, an improved technical solution has appeared in the prior art to solve this technical problem. For example, in the prior art, the children's schoolbag is designed as a trolley schoolbag. Injuries caused by children's bodies, but the trolley schoolbag is very inconvenient when going up and down stairs, buses and on uneven roads, and the wheels of the trolley schoolbag are easy to wear and tear, and it is easy to be caught when the crowd is crowded, especially when primary school students are fighting with each other. Injury from tripping, so it is not advisable to use a trolley bag instead of a normal school bag

However, most of the existing improvements for backpacks are functional improvements, and there are few structural designs to reduce the weight of the backpack, and the above-mentioned technical problems cannot be effectively solved at present.
