Description

EVA shoe outsole structure

This creation is about an EVA shoe outsole structure, especially an EVA shoe that has good flexibility and can conform to the foot movement curve of the walking or running of the consumer's foot, making the consumer more comfortable when walking or running. Outsole structure.

The traditional shoes are made of rubber material, and the outsole has the characteristics of wear resistance, slip resistance and softness, but the weight is heavier, the weight of the shoes cannot be made light, and the color of the outsole of the material is presented. It is also quite monotonous.

Ethylene-vinyl acetate copolymer (EVA) is used to make outsoles because of its light weight, softness, comfort, shock absorption and easy to shape.

In addition, the hardness of the EVA material can be changed by the increase or decrease of the proportion of the foaming agent, and the change of the hardness will also relatively change the wear resistance of the EVA material; that is, when the EVA material is relatively soft, the wear resistance is low and the deformation is easy. When the EVA material is relatively hard, the wear resistance is high and it is not easy to be deformed; therefore, in order to improve the durability of the shoe, the shoe manufacturer usually uses a relatively hard material EVA material as the sole of the shoe, but the shoes of the shoe. The outsole is not able to provide the comfort of the consumer while walking because it cannot change with the movement curve of the human foot during walking or running.

Please refer to the new TW 382911 patent, which is a rubber sole and EVA surface synthetic sole, especially designed for footwear with higher wear resistance. The sole made of rubber and EVA replaces the traditional rubber sole. At the same time, the wear resistance requirement is increased, and the wearing comfort is greatly improved, and the cost is greatly reduced. The structural design is mainly made of a rubber material and a thin layer of the bottom layer, and an EVA material is blended with the rubber to form an elastic surface layer. The vulcanization and fusion type is further formed to form a sole structure having different characteristics, and the rubber structure of the bottom layer imparts high wear resistance, and the EVA material of the surface layer provides appropriate cushioning elasticity for better wearing comfort. And to reduce the overall weight and reduce costs, become a practical and economical innovative sole structure.

Referring to the new TW M392570 patent, it is an EVA double-density sole structure, which is made of EVA foam. The shape is corresponding to the shape of the human foot. It is divided into three parts: the sole of the shoe, the middle part of the shoe and the heel of the shoe. A forefoot wear-resistant area is provided on the sole of the sole of the sole, and a heel wear-resistant area is provided on the heel of the sole of the sole, and the hardness of the forefoot wear-resistant area and the wear-resistant area of the heel Higher than the hardness of the sole, according to the dynamic foot pressure observation, the forefoot wear zone is disposed in the area covered by the front end of each tibia and the thumb of the foot, and the wear-receiving area of the heel is disposed on the corresponding foot The calcaneus is formed to form a sole having the same material and having two different hardnesses, which not only maintains the original better wear resistance, but also reduces the overall weight of the shoe and effectively improves the wearing comfort of the shoe.

The above two patent documents are used to improve the wear resistance or comfort or light weight of the sole of the shoe through the use of the bottom layer of the EVA material. Today, the creator also uses the traditional outsole in the actual implementation. The creation of the creation is based on the missing points.

The main purpose of this creation is to provide an EVA shoe outsole structure.

The main purpose and effect of the above-mentioned creation are achieved by the following specific technical means: an EVA shoe outsole structure comprising a bottom layer and at least one layer of EVA layer, the EVA layer being disposed on the bottom layer, The EVA layer is provided with a plurality of horizontal slots corresponding to the position of the sole of the foot.

The EVA shoe outsole structure as described above, wherein when the EVA layer is two or more layers, the thickness of each of the EVA layers is the same or different, and the lateral slot is only provided in the uppermost layer of the EVA. Floor.

The EVA shoe outsole structure as described above, wherein, when the EVA layer is two or more layers, the thickness of each of the EVA layers is the same or different, and the lateral slots penetrate through the EVA layer of each layer.

The EVA shoe outsole structure as described above, wherein each layer of the EVA layer is selected to have a different color.

The advantages of the EVA shoe outsole structure of this creation are: By using the lateral slots provided on the EVA layer and corresponding to the soles of the feet, the EVA layer can be made to have better flexibility, so that the EVA shoe outsole composed of the EVA layer can be more suitable for the consumer to walk or run. The curve of the foot movement is more comfortable when worn.

In order to make the technical content, creative purpose and the effect achieved by this creation more complete and clear, please elaborate below, and please refer to the illustrated drawings and drawings: please refer to the first As shown in the figure and the second figure, the first figure reveals the stereoscopic appearance of the EVA shoe outsole structure of the present invention, and the second figure reveals the appearance side view of the EVA shoe outsole structure of the present invention.

The EVA shoe outsole structure of the present invention comprises a bottom layer (1) and an EVA layer (2). The EVA layer (2) is disposed on the bottom layer (1), and the EVA layer (2) corresponds to the position of the human foot. a plurality of transverse slots (3) are provided, and the transverse slots (3) may penetrate the thickness of the EVA layer (2) or may not be recessed through the thickness of the EVA layer (2); It is shown that the transverse slot (3) penetrates the thickness of the EVA layer (2).

In addition, the EVA shoe outsole structure of the present invention has an EVA layer (2) of two or more layers. As shown in the fourth and fifth figures, the EVA shoe outsole structure of the present invention has a two-layer EVA layer (2). Of course, the setting of the EVA layer (2) is not limited to the second layer, and may be two or more layers. Wherein, the thickness of each layer of the EVA layer (2) may be the same or different, and the color between the layers of the EVA layer (2) may also be different, so as to increase the color of the EVA layer (2). The variability of the EVA shoe outsole structure further enhances the economic benefits of the EVA shoe outsole structure of this creation. As shown in the fourth and fifth figures, EVA layers (2) of different thicknesses were selected.

Furthermore, when the EVA layer of the present EVA shoe has a multi-layered EVA layer (2), the lateral slot (3) may be provided only in the uppermost EVA layer (2) or through each layer of the EVA layer. (2).

Accordingly, by providing the transverse slot (3) in the corresponding foot on the EVA layer (2), the EVA shoe outsole structure can be better curved, so that the EVA shoe outsole can be more in line with the consumer walking or The curve of the soles of the feet during running is more comfortable to wear.

The above are only some of the examples of this creation, and are not intended to limit the creation of this creation. It should be included in the scope of this patent, based on the creative spirit and characteristics of this creation.

In summary, the present embodiment can achieve the expected use efficiency, and the specific structure disclosed therein has not been seen in similar products, nor has it been disclosed before the application, and has fully complied with the provisions of the Patent Law. And the request, the application for a new type of patent in accordance with the law, please forgive the review, and grant the patent, it is really sensible.
