Description

Sole

The new model relates to a shoe material, especially a shoe sole.

Normal shoes are mainly composed of a cloth or leather upper which is glued to a sole. The sole and the upper together form a foot space for the user's feet to extend into. The sole is made of a single material, such as polyurethane (Polyurethane, PU for short), synthetic rubber, or natural rubber.

However, when the color of the shoe sole is to be changed, since the current sole is made of a single material, it is usually only possible to dye a single material as a whole or gradually, and the color change that can be produced is limited.

Furthermore, when the sole is made of new and unused polyurethane, synthetic rubber, or natural rubber materials, the source of the material is relatively difficult to say that it is environmentally friendly.

Therefore, the purpose of the present invention is to provide a shoe sole that can overcome at least one of the disadvantages of the prior art.

Therefore, the sole of the present invention includes a sole body. The sole body has a bottom surface and a top surface spaced apart from each other. The sole body includes a base and a plurality of particles respectively dispersed on the base. The material of the particles is made of cross-linked Polyurethane (PU for short). ), Ethylene Vinyl Acetate (EVA for short), Polyvinylchloride (PVC for short), Polyolefin elastomer (POE for short), Thermoplastic elastomer (Thermoplastic elastomer) , Referred to as TPE), at least one substance selected from the group consisting of synthetic rubber and natural rubber.

The effect of the present invention is to use the design that the particles are dispersed on the base to provide a sole with innovative structure and maintain the predetermined structural strength and support for the foot.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are represented by the same numbers.

1 to 3, a first embodiment of the sole 1 of the present invention is suitable for being combined with an upper 91 to form a shoe 90, such as a slippers. In the first embodiment, the sole 1 has a single-layer structure and includes a sole body 10. The sole body 10 generally has a sole shape in plan view, and has a bottom surface 11 suitable for contacting the ground, a top surface 12 spaced apart from the bottom surface 11, and a surrounding edge connected to the periphery of the bottom surface 11 and the top surface 12面13。 13. In the first embodiment, the sole 1 serves as a footbed of the shoe 90.

The sole body 10 further includes a base 14 and a plurality of particles 15 respectively dispersed on the base 14 and combined with the base 14. The substrate 14 is made of polyurethane (Polyurethane, PU for short), Ethylene Vinyl Acetate (EVA for short), Polyvinylchloride (PVC for short), and polyolefin elastic Polyolefin elastomer (POE for short), Thermoplastic Elastomer (TPE for short), synthetic rubber and natural rubber. In this embodiment, the substrate 14 is selected from synthetic rubber and natural rubber. In other variations of this embodiment, the substrate 14 includes polyurethane. The size of the particles 15 is 0.1 mm~10 mm, and the material of the particles 15 is made of cross-linked polyurethane, ethylene-vinyl acetate copolymer, polyvinyl chloride, polyolefin elastomer, thermoplastic elastomer, At least one substance selected from the group consisting of synthetic rubber and natural rubber. Specifically, the particles 15 are made of cross-linked ethylene-vinyl acetate copolymer. Based on the base 14 being 100 wt%, the weight percentage of the particles 15 is 10 wt%-50 wt%. In addition, the sole body 10 has a minimum thickness D from the bottom surface 11 to the top surface 12, and the range of the minimum thickness D is not less than 11 mm. Therefore, by spreading the particles 15 on the base 14 with a predetermined size and a predetermined weight percentage, the sole 1 has a predetermined structural strength and provides a predetermined supporting force for the foot when the user wears the shoe 90 .

It should be noted that the particles 15 may also be in the material group composed of recycled polyurethane, ethylene-vinyl acetate copolymer, polyvinyl chloride, polyolefin elastomer, thermoplastic elastomer, synthetic rubber and natural rubber. The selected at least one substance is prepared by crushing, cutting or crushing, and the above-mentioned materials can be fully reused, effectively achieving the effect of environmental protection.

The bottom surface 11 of the sole body 10 also has a plurality of recessed portions 111 spaced apart and recessed in the direction of the top surface 12 respectively, and a protruding portion 112 connected to the recessed portions 111. The concave portions 111 and the convex portion 112 together form a three-dimensional pattern structure of concave and convex, and can be used to prevent slippage when the bottom surface 11 contacts a ground, especially when the ground is a smooth or slippery surface. Can highlight the effect of anti-slip.

The manufacturing process of the sole 1 is mainly to first mix a softened base preparation material and the particles 15 to form a mixture, and then put the mixture into a mold for hot pressing. Depending on the material of the base 14, use the base 14 Taking synthetic rubber or natural rubber as an example, the heating temperature is 140°C to 160°C, and the heating time is 5 minutes to 10 minutes; finally, trimming is performed to become the sole 1. Because the sole 1 is formed by mixing the shaped solid particles 15 into the softened base preparation material and forming it by hot pressing, there is a boundary area between the base 14 and the particles 15.

Because the particles 15 are firmly bonded to the substrate 14, and part of the surface of the particles 15 is exposed from the substrate 14, and the substrate 14 together constitute the bottom surface 11, the top surface 12 and the surrounding surface 13. Therefore, when the color of the particles 15 and the color of the base 14 are different, the sole body 10 with two colors interlaced will appear. Furthermore, the particles 15 can also be controlled to have different colors or different colors. For example, some of the particles 15 are a first color, and the remaining ones of the particles 15 are a different color from the first color. The second color of one color enables the sole body 10 as a whole to produce a multi-color interlaced effect.

Referring to FIG. 4, the shoe 90 can also have an insole 92 combined with the top surface of the sole 1, which can also expose the bottom surface 11 and the surrounding surface 13 of the sole 1 to the outside, and is a multi-color interlaced sole 1.

Referring to Figure 5, in other variations of this embodiment, the sole 1 is used as a large sole, and an adhesive (not shown) can be used to form a single material without the A midsole 93 made of particles 15 is adhered between the top surface 12 of the sole body 10 and the bottom surface of the insole 92, and the upper 91 is bonded to the insole 92 to form, for example, a sports shoe or casual shoe Of shoes 90. Among them, the material of the midsole 93 made of a single material is, for example, but not limited to, polyurethane, ethylene-vinyl acetate copolymer, polyvinyl chloride, thermoplastic elastomer, synthetic rubber or natural rubber; or according to actual needs, The midsole 93 is directly thermally pressed to the top surface 12 of the sole body 10, and the adhesive is omitted.

Refer to Fig. 6, which is a second embodiment of the new sole 1. This second embodiment is similar to the first embodiment, except that the sole 1 of the second embodiment is used as the midsole and is suitable for The adhesive (not shown in the figure) or directly heat-compresses it to a large bottom 94 that is made of a single material and is integrally formed without the particles 15. It should be noted that the bottom surface 11 of the sole 1 of the second embodiment may not have the recessed portions 111 and the protruding portions 112 but a flat surface, or the bottom surface 11 of the sole 1 may be a sole made of the single material The top surface of 94 has complementary concave and convex shapes, which can be combined with each other without gaps.

Referring to Figures 7 and 8, it is a third embodiment of the new sole 1. The third embodiment is similar to the first embodiment. The difference is that the third embodiment also has a stack and is combined with The auxiliary layer body 2 of the top surface 12 of the sole body 10 has a double-layer structure. The auxiliary layer body 2 similarly to the sole body 10 includes an auxiliary substrate 21 and a plurality of auxiliary particles 22 dispersed on the auxiliary substrate 21. The material of the auxiliary substrate 21 is different from that of the substrate 14 (Figure 1), but it is also made of polyurethane, ethylene-vinyl acetate copolymer, polyvinyl chloride, thermoplastic elastomer, synthetic rubber, and natural rubber. A substance selected from the group of substances. The auxiliary particles 22 are made of materials that are cross-linked polyurethane, ethylene-vinyl acetate copolymer, polyvinyl chloride, polyolefin elastomer, thermoplastic elastomer, synthetic rubber, and natural rubber. The selected at least one substance may be the same or different from the material made of the particles 15. The auxiliary particles 22 can also be made of recycled polyurethane, ethylene-vinyl acetate copolymer, polyvinyl chloride, polyolefin elastomer, thermoplastic elastomer, synthetic rubber, and natural rubber. At least one substance selected. In the third embodiment, the auxiliary layer body 2 is directly thermally pressed to the top surface 12 of the sole body 10.

In summary, the new sole 1 of the present invention utilizes the design of the particles 15 dispersed on the base 14, so that the sole 1 can not only have the predetermined structural strength and supporting force, but also utilize the base 14 and the particles. The color of 15 has different characteristics, so that the sole 1 presents a rich variety of colors and effectively enhances the visual effect. In addition, when the particles 15 are from recycled materials, the effect of environmental protection can be effectively implemented, so it can indeed achieve the purpose of cost innovation.
