Airbag for shoes and its processing technology

Abstract

The invention relates to the technical field of airbags, in particular to an airbag for shoes, comprising an upper film and a lower film, the upper film can completely cover the lower film, and an airbag cavity is formed between the upper film and the lower film. The airbag of the present invention is composed of an upper film and a lower film. The upper film and the lower film are not of the same area, nor are they of the same shape that can be scaled in equal proportions. However, the shape and area of ​​the upper film can completely exceed and cover the lower film. When the air bag is combined with shoes and clothing Finally, the upper film with a larger shape and area is exposed to the outside public, while the lower film is hidden between the upper film and the clothing, ensuring the flatness of the joint between the shoes and clothing and the airbag; in the hot pressing process, The edge of the lower film is hot-pressed and bonded to the shoe upper, while the edge of the upper film is hot-pressed and combined with the lower film to form an airbag, and the outer edge is hot-pressed on the shoe upper, so that the airbag is covered with the edge and hot-pressed on the upper when it is formed. , which improves the airtightness and is not prone to air leakage.

Description

technical field [0001] The invention relates to the technical field of airbags, in particular to an airbag for shoes and a processing technology thereof. Background technique [0002] Inflatable articles of manufacture or bladders for inflatable articles of manufacture have been known for decades. Such manufactured items include inflatable air mattresses and pillows, lifeboats and buoys, and sports equipment. In the field of sports equipment, air bags have been incorporated into the interior of balls, such as basketballs, footballs, soccer balls, etc., and into apparel and protective equipment such as baseball and boxing gloves, helmets, chest protectors, and footwear. [0003] For example, when used in footwear, air cells can be used to provide customized cushioning and improve fit to the wearer's foot. In some cases, air cells may replace shoelaces to secure the shoe to the wearer's foot. Air cells can also be used in the sole of a shoe to cushion the bottom of the wear...

AI Technical Summary

Problems solved by technology

[0006] This kind of practice guarantees the making of airbag, but when being used for footwear (clothing and protective equipment such as baseball and boxing gloves, helmet, chest protector and footwear), there are following deficiencies: (1) airbag edge is combined with footwear There is an obvious difference in the thickness of the two layers of TPU film, resulting in low flatness at the joint between the shoes and the airbag; When the wearer moves and squeezes, it is easy to cause air leakage; (3) The common airbags on the market need to make two TPU films of the same shape and size into the airbag first, and then they can be heated by hot pressing or other methods. Combining the airbag with the upper, the processing technology is not convenient
