Backpack with an elastic breathable fabric

Abstract

A backpack with an elastic breathable fabric contains a body and an elastic breathable fabric. The body includes an outer surface, a back surface, at least one strap connected with the back surface, a receiving space defined between the outer surface and the back surface, and a contacting portion formed on a central position of the back surface. The elastic breathable fabric, is formed in a mesh shape, has a pre-set tension, and is fixed on the contacting portion of the back surface of the body. Also, the elastic breathable fabric includes a plurality of tiny holes so that the elastic breathable fabric communicates with the receiving space. Thereby, when the elastic breathable fabric contacts with the user's back, it provides breathable wicking function. Also, the elastic breathable fabric has the pre-set tension to recover elasticity quickly, thus reducing carrying pressure to user's body.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a backpack, and more particularly to a backpack with an elastic breathable fabric which obtains breathable perspiration, enhances comfort, and reduces carrying pressure.BACKGROUND OF THE INVENTION[0002]Conventional backpack with a fixed breathable member is disclosed in TW Pat. No. 099224480 and contains a body. The body includes a back surface and two carrying straps mounted on the back surface; two weave straps sewed with the two carrying straps of the body, wherein each weave strap has a connector and a buckle so as to adjust its tightness and length; four flexible pads covered on the back surface of the body; at least one locking assembly defined between the two weave straps so as to fix user's chest and waist.[0003]However, the four flexible pads contact with the user's back, thus causing poor ventilation and sultriness.[0004]Another conventional backpack with a removable breathable member is disclosed in US publicati...

AI Technical Summary

Benefits of technology

The invention is a backpack with a special fabric that allows air and sweat to pass through, making it more comfortable and reducing carrying pressure. The fabric is fixed to the back of the user and creates a breathable effect. It also quickly recovers its elasticity, so the user is not carrying too much weight. The fabric can be sewn, glued, hot melted, or high-frequency welded to make manufacturing easier.

Problems solved by technology

However, the four flexible pads contact with the user's back, thus causing poor ventilation and sultriness.

Nevertheless, such a breathable mesh fabric has complicated structure, and the upper side of the backpack supports the user's shoulder by using the two supporting corners and a lower side of the backpack supports the user's buttock, such that support points generates on the upper side and the lower side of the backpack, so the user's back cannot support and carry the backpack properly, thus having using comfort and carrying pressure to the user's body.
