Sole structure with three-dimensional shape and texture

The present invention relates to the technical field of the structure of a sole, in particular to a surface which can make the surface of the sole have good waterproofness and wear resistance to enhance the service life and practicability, and also can make the surface of the sole have a delicate and clear three-dimensional shape. The sole structure with a three-dimensional shape and texture on the surface of the road to increase product diversification and overall beauty and texture.

The materials of the early soles are made of materials that are less waterproof and less wear-resistant. Therefore, after a period of use, it is easy to be eroded, deteriorated and worn by water to shorten the service life. Moreover, in the early soles for aesthetics and advertising effects, the Metropolis painted the pattern, color or trademark on the circumference of the sole, but because the circumferential surface of the sole is easily worn, and the water will also erode the sprayed paint, which is prone to occur. The problem of fading or color shedding.

In order to improve the above problems, a manufacturer has developed a conventional sole structure as disclosed in Japanese Patent Publication No. 00583919, which is mainly to heat-melt a TPU film (Thermoplaspic Polyurethane Urethane thermoplastic polyurethane) on the circumferential surface of a sole body. The urethane film) uses the TPU film to produce a protective and decorative effect to achieve waterproof, abrasion and aesthetic effects. However, due to In the conventional sole structure, the TPU film is bonded to the circumferential surface of the sole body by heat-pressure fusion, so that the circumferential surface of the sole body needs to be smooth to make the TPU film be flatly bonded. When the circumferential surface of the sole body has a rough three-dimensional shape or a three-dimensional texture, the TPU film may not be attached to the circumferential surface of the sole body by heat-pressure fusion. A true and uniform entire surface is pressed against the circumferential surface of the sole body, so that a gap (especially at a depression or a turning point) is easily generated between the TPU film and the circumferential surface of the sole body, so that it cannot be firmly bonded. Further, it is easy to fall off, and the gaps are also easy to invade the water to shorten the service life of the sole. Therefore, the surface of the conventional sole structure cannot have a special and diversified three-dimensional shape, and if it is intended to have a three-dimensional texture, it can only be formed by first forming a three-dimensional texture on the TPU film and then thermocompression bonding thereto. The sole body, but this is limited by the thickness of the TPU film, and can only form a very shallow three-dimensional texture, so the three-dimensional texture finally formed on the surface of the shoe body can not be very delicate and clear, and After a period of time, it is easy to be damaged or disappeared, which affects the overall beauty and texture.

The main purpose of this creation is to solve the problem that the sole structure with waterproof and wear-resisting effect can only be used to change the color and pattern on the TPU film to increase the shape change, and it is impossible to form a delicate and clear three-dimensional shape and texture on the surface. , which in turn leads to problems such as simple and rigid shape and the inability to raise consumer desires.

This creation provides a sole with a three-dimensional shape and texture. The structure comprises a sole body and at least one skin. Wherein, the sole system forms a shape corresponding to a human foot in a foam molding manner, and the circumferential surface of the sole body has a plurality of three-dimensional shapes and at least one three-dimensional texture. The skin comprises an outer layer on the outer side and a joint layer on the inner side, and the joint layer is viscous for bonding to the surface of the sole body when heated and molten, by placing the skin on the skin The outer side of the circumferential surface of the sole body is then heated and evacuated to form a tight hot-melt bond of the skin along the three-dimensional shape of the surface of the sole body with the three-dimensional texture.

The sole structure provided with the three-dimensional shape and texture of the surface of the present invention can form a close hot-melt fit along the three-dimensional shape and the three-dimensional texture of the surface of the sole body by heating and vacuuming, and further When the skin is adhered to the surface of the sole body, it is more vague and firm, and the same three-dimensional shape and three-dimensional texture as the circumferential surface of the sole body are clearly formed. Therefore, the surface of the sole can be improved in water repellency and wear resistance by using the skin to improve the service life and practicability, and the surface of the sole can have a delicate and clear three-dimensional shape and texture to increase product variety. And the overall beauty and texture.
