Abstract

An improved structure for the midsole of air cushion shoes, especially sandwiched by a top midsole and a bottom midsole An air cushion is laminated and glued together. The bottom midsole is recessed on the other side of the arch of the wearer to fill in the air cushion, and then overlapped with the top midsole to form a complete air cushion shoe midsole. With this structure, it is possible to improve the conventional air-cushioned shoe midsole. Only a single one-piece midsole is formed by opening a hole corresponding to the middle of the arch of the wearer's foot and squeezing into the air cushion, which makes the production process labor intensive and inconvenient. The hardness of the top midsole material can be prefabricated to be softer and more comfortable than the bottom midsole. The hardness of the bottom midsole closer to the ground is prefabricated to be more elastic and tough than the top midsole material to increase the cushioning resilience of the ground. Effector.

Description

Improved structure of air cushion shoe midsole

This creation is related to an improved structure of an air cushion shoe midsole, especially a novel air cushion shoe midsole structure technology that changes the air cushion shoe midsole from a top midsole and a bottom midsole to sandwich an air cushion stack. .

The midsole of conventional air-cushioned shoes is only made of Polyurethane (PU) material. The midsole is made of polyurethane (PU). The overall material density of a single midsole produced by the molding method is the same, and it cannot be specifically distinguished in the same molded air cushion shoe midsole. The top density is lower than the bottom, which is softer and more comfortable, and the bottom density closer to the ground is prefabricated than The top is denser, so that the bottom enhances the elasticity and shock-absorbing resilience when stepping on the ground, that is to say, eliminates the cushioning and shock absorption performance brought by the air cushion itself. Only in terms of pure shoe midsole performance, a single molded midsole material is commonly used. If you want to wear a more comfortable foot feel in production, it is often impossible to take into account the improvement of the elasticity of the ground. On the contrary, it is necessary to increase the elasticity of the ground. Comfortable foot feel.

In view of the various deficiencies in the midsole structure of air-cushion shoes, the creator actively conceived a solution. After many experiments and discussions, the original creation was finally produced.

Therefore, this creation is to provide an improved structure for the midsole of air-cushioned shoes. The top midsole and a bottom midsole are laminated and laminated with an air cushion. The bottom midsole is recessed on the other side of the arch of the wearer to fill in the air cushion, and then it is up and down with the top midsole. The midsole of the air-cushioned shoe is laminated and glued to form a complete air-cushioned shoe midsole, which can improve the conventional air-cushioned shoe midsole. Only a single integrally formed midsole is pressed into the air cushion by opening a hole corresponding to the middle part of the arch of the wearer's foot, which makes the production process labor intensive. The lack of inconvenience makes the production process of inserting the air cushion into the midsole smoother and faster. This is the main purpose of the creation.

In addition, the improved structure of the midsole of this kind of air cushion shoe in this creation, the material strength of the top midsole can be prefabricated to be softer and more comfortable than the bottom midsole. This is another purpose of the creation.

Furthermore, the improved structure of the air-cushioned shoe midsole of this invention, the hardness of the bottom midsole closer to the ground can be prefabricated to be more elastic than the top midsole material, so as to increase the shock-absorbing resilience of stepping on the ground. This is another purpose of this creation.

In addition, the improved structure of the air-cushioned shoe midsole of this invention can be made of ethylene-vinyle acetate copolymer (EVA) foam material to make the top midsole and the bottom midsole, which is lightweight and not easy to hydrolyze. This is another purpose of this creation.

As for the detailed structure, application principle, function and effect of this creation, please refer to the following description with the accompanying drawings to get a complete understanding.

The first picture is an exploded view of the improved structure of the midsole of this creative air-cushion shoe. Please refer to the top view of the second picture and the side view of the third picture at the same time. As shown in these pictures, it can be seen that in this creative air-cushion shoe The improved structure of the sole is tied to the sole leather 1. A top midsole 3 and a bottom midsole 5 sandwich an air cushion 4 stacked and bonded to form an air cushion shoe midsole 2, wherein the bottom midsole 5 bears the wearer. On the other side of the arch of the foot, an air cushion half-inlaid hole 5A is recessed to fill in the air cushion 4, and then overlap with the top midsole 3 to form a complete air cushion shoe midsole 2. The bottom midsole 5 and the top midsole 3 can be separated It is foamed and molded with ethylene-vinyle acetate copolymer (EVA) material, and is laminated to the bottom midsole 5 corresponding to the top and rear ends of the recessed air cushion semi-recessed cavity 5A, protruding flat against the rear wall of the top midsole 3 The heel pad part 5B of the edge, and the front edge of the top midsole 3 corresponds to the front edge of the foot slightly beyond the front edge of the bottom midsole 5, and protrudes downwards to flatten against the vertical stop 3A of the front wall edge of the bottom midsole 5. The heel pad portion 5B and the hanging block 3A enable the front and rear ends of the top midsole 3 and bottom midsole 5 that are superimposed to be adhered to each other to form a more stable laminated structure.

With this structure, the three-dimensional shape of the entire air cushion shoe midsole is as shown in the fourth figure, and the implementation for the sports shoe body is as shown in the fifth figure. The air cushion 4 is sandwiched and glued to form the air cushion shoe midsole 2. In addition, the hardness of the top midsole 3 material can be prefabricated to be softer and more comfortable than the bottom midsole 5, and the bottom midsole 5 hardness prefabricated closer to the ground is more elastic than the top midsole 3 material. , In order to increase the effect of treading on the ground shock absorber resilience.

In summary, the improved structure of the air cushion shoe midsole of this creation does achieve the stated effect, and it has not been publicly used. It is in compliance with the provisions of the Patent Law. I urge the grant of a patent, which is indeed a virtue. Poop.

Those who need to be clarified, the above are the preferred and specific embodiments of the creation. If the changes made according to the conception of the creation, or the resulting functional effects, still do not exceed the spirit covered by the specification and illustrations, All should be combined with Chen Ming within the scope of this creation.
