Description

Backrest backpack

This creation is about a back-mounted backpack, especially a backpack that can be carried and towed.

Press, there is a kind of towed backpack on the market. The backpack can be combined with a towable trailer. By dragging the backpack with the tug on the trailer, it can be used as a suitcase. However, such a trailer combined with a backpack is still attached to the backpack. After being used for towing, the trailer cannot be completely stored due to its large size, which causes inconvenience in use.

Moreover, because the combination of the trailer and the backpack is not a fixed structure like a suitcase, but is separately combined. The combination of the two is generally achieved by using a rope belt or a matching male and female buckle to achieve mutual integration, but there is often a case where the combination of the backpack and the back frame is loose, and the reason for the poor combination includes the insufficient bearing capacity of the combined structure itself. Especially in the case of heavy objects, it is easy to be shaken by the road surface during towing, and the influence of the shift of the center of gravity is increased, and the rope belt is torn and deformed due to insufficient bearing capacity, and the backpack is gradually loosened. Then, the cracked backpack face is pulled, which makes it difficult to recover.

In view of this, there are still some shortcomings and unsatisfactory things in the past, and the case is improved through the creator's research and improvement, and the creation is created in the end, and the following examples illustrate the characteristics of the case.
