Description

An elastic carrying device and elastic backpack

technical field

The present application relates to the technical field of human wearable devices, and in particular, to an elastic carrying device and an elastic backpack.

Background technique

Backpacks have unique advantages as a transportation method that humans have used for thousands of years, such as freeing hands, stability and reliability. Therefore, backpacks have become one of the preferred solutions for people to carry their belongings today. Soldiers usually travel for long periods of time with heavy loads. When walking with a load on the back, the muscles of the lower limbs of the human body will do extra work, which will lead to fatigue of the muscles of the lower limbs, and it is impossible to walk with weight for a long time. Moreover, the shoulder straps of most backpacks are basically fixed on the back of the backpack, so when the center of gravity vibrates up and down during walking, the pressure on the shoulders of the backpack is very large, resulting in sore shoulder muscles, which will increase the fatigue of the human body. .

Because of this, elastic backpacks with cushioning function came into being. The existing elastic backpack separates the backpack from the back of the human body, and makes the backpack vibrate up and down so that the person is basically maintained at the same level when walking, which can effectively reduce problems such as muscle soreness and increase the weight-bearing distance.

However, although the existing elastic backpack can reduce the energy loss of the human body, it is very difficult to assemble and disassemble due to its integrated structure, and the assembly and disassembly speed is slow, which is very inconvenient to use. For soldiers, this can result in wasting valuable time during encounters.
