Description

Technical Field

[0001] The utility model relates to a sole, in particular to a wear-resistant TPR sole. Background Art

[0002] As an important part of footwear products, the sole is in direct contact with the ground. Generally, the common characteristics of sole materials should include wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy to fit the foot shape, not easy to deform after shaping, heat preservation, easy to absorb moisture, etc. At the same time, it should cooperate with the midsole to have a braking effect when walking and changing feet so as not to slip and be easy to stop. The TPR sole has the characteristics of high production efficiency and recyclability, and is widely used in casual shoes by the footwear industry. However, the TPR sole has poor high-temperature wear resistance, the sole is easy to be worn through, and the heel friction of people with out-toed feet is more severe, with poor wear resistance.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0022] In the description of the present invention, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like are involved, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0023] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] As Figure 1 and 2 shown, a wear-resistant TPR sole includes a sole body 1, and a wear-resistant member 2 is provided on the bottom surface of the sole body 1. The wear-resistant member 2 includes a rubber sheet 21, an inner wear-resistant layer 22, a fabric 24, and a TPR wear-resistant layer 25 that are sequentially bonded and connected. The multi-layer structure improves wear resistance from the inside to the outside. The TPR wear-resistant layer is injection-molded from TPR material and has good wear resistance. Even if it is worn, through the protection of the fabric, the inner wear-resistant layer and the rubber sheet, the multi-layer protection can effectively prevent the sole from being worn through.

[0025] The inner wear-resistant layer is formed by pouring polyurethane material. After the fabric and the TPR wear-resistant layer are both worn, the inner wear-resistant layer can further play a role in preventing wear, rather than being directly discarded after the outermost layer is worn. The rubber sheet, as the innermost anti-wear structure, plays the final anti-wear role.

[0026] The inner wear-resistant layer is adhesively connected to the fabric by a hot-melt method. For the hot-melt method, it can be realized by the following two methods:

[0027] Hot-melt glue is coated on the surface of the inner wear-resistant layer 22, and the fabric 24 is adhesively connected to the inner wear-resistant layer through the hot-melt glue. Or a hot-melt adhesive film 23 is pressed on the surface of the inner wear-resistant layer 22, and the fabric 24 is adhesively connected through the hot-melt adhesive film 23. The thickness of the hot-melt adhesive film 24 can be selected to be 0.15 - 0.3 MM. The high-temperature hot-melt adhesive film can withstand temperatures above 120 °C. Under relatively high-temperature conditions, the hot-melt adhesive film melts, thereby realizing the adhesive connection between the inner wear-resistant layer and the fabric.

[0028] Protrusions 5 are integrally formed on the TRP wear-resistant layer 25, and a concave cavity is provided on the fabric. The protrusions are fitted into the concave cavity, which can ensure a tighter connection between the TPR wear-resistant layer and the fabric.

[0029] Interlaced patterns are provided on the TPR wear-resistant layer to further improve the wear resistance.

[0030] Both the inner wear-resistant layer and the fabric are provided with a plurality of holes, and the plurality of holes are arranged in an array, and the holes are through holes. When the hot melt glue is coated on the surface of the inner wear-resistant layer, part of the glue will penetrate through the holes on the inner wear-resistant layer and bond to the rubber sheet, and part of the glue will penetrate through the holes on the fabric and bond to the TPR wear-resistant layer. Through hot melt bonding, the connection between the layers is formed, which is more stable. And the hot melt adhesive film will also melt at a higher temperature environment and penetrate into the holes to form a stable bond.

[0031] The utility model realizes the effective improvement of wear resistance through a multi-layer structure, and avoids the sole of the shoe being easily worn and the whole shoe being discarded.

[0032] When setting, since the heel position is the most easily worn, usually only wear-resistant parts need to be set at the heel position.

[0033] It should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
