Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of shoes and clothing, and specifically, to an inflatable airbag connecting the arch of the foot. Background Art
[0002] With the improvement of people's health awareness and the pursuit of comfort, footwear products are constantly evolving towards a more user-friendly and functional direction. As an important part of the human body, the foot bears a huge amount of pressure during daily activities. Therefore, it is particularly important to wear a pair of shoes with good support and shock absorption effects. Traditional sole designs mostly use single materials such as EVA (ethylene-vinyl acetate copolymer), PU (polyurethane), or rubber. Although these materials have certain elasticity and durability, they have certain limitations in providing foot support, especially in terms of insufficient support for the key part of the arch of the foot.
[0003] Early sole designs mainly used single materials such as EVA, PU, or rubber, which were widely used because of their light weight, durability, and certain elasticity. Traditional sole designs usually include an outsole, a midsole, and an insole. The outsole is used to provide abrasion resistance and traction; the midsole is responsible for absorbing impact and providing cushioning; the insole is the part that directly contacts the foot, and usually some soft materials are added to improve comfort.
[0004] In recent years, with the progress of materials science, many new materials have emerged, such as memory foam, carbon fiber composite materials, etc. The application of these new materials has significantly improved the performance of the sole. Modern sole designs focus on structural innovation, such as using a dual-density midsole design, built-in air cushion technology, etc., to provide better shock absorption effects and foot support. With the application of 3D printing technology, more and more brands are starting to offer personalized customization services, and the sole can be customized according to the user's foot shape and gait characteristics.
[0005] In terms of arch support technology, some sports shoes and casual shoes will add additional support materials under the insole, such as plastic plates, foams, or gel pads, etc., to provide arch support. Traditional arch support designs are often fixed and difficult to adapt to the differences in arch height and weight of different users. Once the shoes are manufactured, the strength of the arch support cannot be changed, which makes it impossible for users to obtain the best support effect when their weight changes or their foot conditions change. In addition, the existing arch support systems are usually static and cannot automatically adjust according to the user's gait or activity intensity, so the support effect during activities such as running and jumping is limited. Summary of the Invention
[0006] To solve the technical problems of the non-adjustable support strength and lack of dynamic adaptability in the existing arch support design, the present invention provides an inflatable airbag connecting the arch of the foot.
[0007]
The present invention discloses an inflatable airbag connecting to the arch of the foot
[0008] Preferably, the inflatable airbag is composed of an upper TPU film and a lower TPU film connected to each other along the edge, and an airbag cavity reserved between the upper TPU film and the lower TPU film.
[0009] Preferably, the inflatable airbag is connected to the shoe. The vamp airbag part is arranged above the surface of the vamp sheet material, the arch airbag part is arranged under the insole, and the connecting part extends from the surface of the vamp sheet material along the inner side of the shoe to under the insole to connect the vamp airbag part and the arch airbag part.
[0010] Preferably, a covering layer can also be arranged on the upper surface of the vamp airbag part.
[0011] Preferably, the vamp airbag part can be arranged in at least one area on the surface of the vamp sheet material.
[0012] By adopting the above technical solutions, the beneficial effects of the present invention are as follows: In the prior art, additional support materials such as plastic plates, foams or gel pads are usually used for arch support, and their settings are often fixed. Once the shoes are manufactured, the arch support strength cannot be changed. However, the inflatable airbag of the present application has an arch airbag part. Through the inflation and deflation mechanism of the airbag, users can easily adjust the arch support strength according to their own needs, so as to provide more appropriate support and reduce foot fatigue, especially arch fatigue. At the same time, the integrated design of the vamp airbag part and the arch airbag part enables the user's instep and arch to obtain better wrapping at the same time, improving the wearing comfort of the shoes.
