Description

Shoe cushion device

A shoe air cushion device of the present invention specifically refers to the technology applied in the field of footwear. Its main technology is to provide the insole corresponding to the forefoot when the wearer is stepping on the shoes. The insole corresponding to the forefoot can be adjusted at any time according to the size of the stepping force. , So that the forefoot can be comfortably cushioned when walking, running and jumping, etc., which is an invention with excellent practicality.

Shoes are the best protection for the feet. They can not only keep out the cold, but also prevent damage to the feet caused by foreign objects. Therefore, shoes are indispensable for people. A pair of comfortable shoes can Providing people to walk longer, run faster, and jump farther is the goal that all businesses have pursued for many years. However, most of the above goals on the market will have insoles in the shoes, and there are many types of insoles. For example, the more common general insoles, such as the type of patent announcement number I644631, but also functional insoles, such as the patent announcement number M551846 "breathable and shock-absorbing insole", I538631 "air cushion shoe body", etc. The discussion is about functional insoles. The most important feature of the above-mentioned functional insoles is that they can achieve cushioning and breathable effects to match the wearer's use of walking, running, jumping and other related foot movements.

However, the above-mentioned functional insoles are used to circulate and replenish the air cushion through repeated pedaling. Although they can provide the comfort of the wearer’s feet, they ignore a problem, which is when the air cushion corresponds to the forefoot. Part, when the internal gas When the body is overfilled, the air cushion will be too hard, which will greatly reduce the shock absorption effect, and when the gas in the air cushion is overfilled, it will explode. Most of the inflatable insoles are made by high-frequency welding. Therefore, when the gas in the air cushion is overfilled, the wearer’s instant stepping force, whether it is from the rear heel or directly from the forefoot, will easily cause the air cushion to burst from the weld. Inflatable insoles still have certain problems in use. The relevant industry still needs to think carefully about how to adjust and improve it to prevent the inflatable insole from bursting, and the inflatable insole cannot effectively absorb shock.

In view of the above situation, the inventor devoted a lot of time to research related knowledge, compared the advantages and disadvantages, carried out research and development of related products, and went through many experiments and tests, and finally launched a "shoe air cushion device" to improve the above shortcomings , To meet the needs of the public.

The main purpose of the present invention is to provide the air cushion corresponding to the forefoot when the wearer wears shoes walking, running and jumping, and the amount of gas filling is relatively moderate, and the air cushion corresponding to the forefoot will not be overfilled, which is more suitable for the wearer when pedaling. It has comfort and softness but maintains the effect of cushioning and shock absorption, and at the same time, it provides the wearer with more comfort when wearing and stepping on. It improves the inflatable insoles listed in the prior art, which will cause bursts and bursts due to over-inflation. Overfilling of gas will also cause the air cushion to be too hard, making the wearer feel uncomfortable during walking, running and jumping. To this end, the inventors tried their best to achieve the objectives and effects of the aforementioned invention. An air cushion device for shoes of the present invention, which is installed in the shoe body and pressed by the foot, includes: a front air cushion corresponding to the forefoot of the foot ; A middle air cushion, which corresponds to the foot socket of the foot, the middle air cushion is provided with a first air inlet pipe and a first air outlet pipe, and the first air inlet pipe and the first air outlet pipe are connected to the air cushion at one end, and The first outlet pipe another The end is connected to the front air cushion, and a first one-way valve is arranged in the first air outlet pipe, and the first air inlet pipe is connected to the inside of the shoe body and sucks air into the middle air cushion, and the first air inlet There is a second one-way valve in the tube to restrict the direction of outside air entering, and the gas in the middle air cushion is guided into the front air cushion for filling; and a rear air cushion, which corresponds to the rear heel of the foot, and the rear air cushion is provided with a second inlet A trachea and a second air outlet. One end of the second air inlet pipe is connected to the rear air cushion and the other end is provided with a suction hole. The suction hole sucks the gas from the shoe body into the rear air cushion and is pressed by the heel The second air outlet pipe exits the shoe body, and the second air inlet pipe is provided with a third one-way valve, which restricts the second air inlet pipe to guide the air after the shoe body is sucked; wherein, the front The gas to be filled in the air cushion penetrates the depression of the foot socket to slightly compress the compression of the air cushion, so that the gas filling the front air cushion is not too full and too hard, and maintains the softness of the front air cushion and has a buffer, The effect of shock absorption.
