Description

Shoe outsole structure

The technical field of this creation is about the outsole structure of the shoe.

The common characteristics of the general sole material of the shoe include abrasion resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, and deformation. There are many types of materials for soles, including natural rubber, synthetic rubber, and plastics (PVC, PU, TPR, EVA...). Based on meeting various functional requirements and various surface effects, the combination of different materials has become a trend. The combination technology of the different material soles can realize the double-layer (or multi-layer) shoe outsole structure, and can also realize the outsole decoration of the shoes. Double-layer (or multi-layer) shoe outsole structures are typically combined with two layers of different materials using injection or foam forming techniques. The outsole modification of the shoe can also be shot or foamed, or it can be embedded and bonded.

The above-mentioned double-layer (or multi-layer) shoe outsole structure changes the function of the outsole of the shoe through the synergistic action of the materials, such as elasticity, wear resistance, supportability, and the like. The technique of hemming modification has so far only modified the side of the outsole of the shoe.

The creator of the present invention believes that the above-mentioned double-layer (or multi-layer) shoe outsole structure and the edging structure have an improved space, and the improvement thereof should focus on providing more protection for the easily hydrolyzed sole layer (for example, PU layer) and prolonging. The service life of the outsole of the shoe is further derived from the more refined surface finish.

The purpose of the present invention is to provide a shoe outsole structure which improves the disadvantages of the double layer (or multi-layer) and the edging modified shoe outsole described in the prior art, thereby realizing the sole for protecting the easily hydrolyzable material. The layer, the life of the outsole of the shoe is extended, the sole of the shoe is at least double-layered, and the upper side of the shoe has a glossy and fine surface.

The shoe outsole structure of the present invention achieves the above object, comprising a first sole layer, a second sole layer coupled to the first sole layer, and a second sole layer and the first sole layer a film that extends over the sidewall of the second sole.

For the convenience of the description, the central idea expressed in the column of the above novel content is expressed by a specific embodiment. Various items in the embodiments are depicted in terms of ratios, dimensions, amounts of deformation, or displacements that are suitable for illustration, and are not drawn to the proportions of actual elements, as set forth above.

As shown in the first to fourth figures, the sole bottom structure of the present shoe includes a first sole layer 10, A second sole layer 20 is coupled to the first sole layer 10, and a protective film 30 is bonded between the second sole layer 20 and the first sole layer 10, and the protective film 30 is extended and covered. The shoe side wall 21 of the second shoe bottom layer 20.

Further, the material of the first sole layer 10 includes, but is not limited to, natural rubber, synthetic rubber, polyvinyl chloride (PVC), thermoplastic rubber (TPR), ethylene vinyl acetate (Ethylene Vinyl Acetate). , EVA). The material of the second sole layer 20 is selected from, but not limited to, polyurethane (PU). The material of the film 30 is selected to include, but is not limited to, Thermoplastic Polyurethane (TPU), and the thickness of the film 30 is about 0.1 mm to 0.4 mm. .

A method for making the outsole of the present invention is described in the fifth to seventh embodiments. This method is only used to illustrate the creation, but is not intended to limit the implementation of the creation. As shown in the fifth figure, the first sole layer 10 is formed in a cavity of the lower mold 41 of a mold 40. The upper surface of the formed first sole substrate 10 has a groove 11 for flattening the protective film 30. The upper surface of the lower mold 41 covers the cavity and the first sole layer 10; as shown in the sixth figure, the upper mold 43 and the lower mold 41 are clamped, and the polyurethane material is passed through the injection hole 431 of the upper mold 43 ( PU) 201 is injected into the mold 40 on the film 30, and the film 30 and the PU material are lowered into the groove 11 of the first shoe bottom layer 10 due to the weight of the material, and the mold along the lower mold 41 The peripheral surface of the hole is laid, and when the polyurethane material (PU) is injected for a predetermined amount, the injection is stopped. As shown in the seventh figure, the mold is heated to shape the polyurethane material (PU) therein, and after a molding time, the mold outsole is taken out. As shown in the eighth figure, the shoe outsole type includes a second sole layer 20 and a first sole layer 10, and a protective film 30 is disposed therebetween, and the protective film 30 extends over the shoes of the second sole layer 20. The side wall 21 is contoured and has a residual material 31 extending upward. The shoe outsole structure as shown in the first figure can be obtained by a procedure for removing the remaining material along the edge of the shoe.

In the present embodiment, the second sole layer 20 is made of a polyurethane (PU) material, which has the advantages of light weight, good elasticity, density and hardness in the process, adjustable impact resistance, good heat insulation performance, and the like. However, the disadvantage is that the weather resistance is not easy to be hydrolyzed. To solve this disadvantage, the second shoe sole 20 is protected by a thermoplastic polyurethane (TPU) film 30, which has wear resistance. Good tear resistance, good bending strength, high tensile strength, large elongation at break, low temperature resistance (-50 ° C), low long-term compression set, oil resistance, aliphatic solvent resistance, hydrocarbon solvent resistance, oxygen and The odor is resistant and aging resistant, and in particular, the protective film 30 covers the sidewall 20 of the second sole layer 20, thereby avoiding the problem of hydrolysis of the second sole layer 20 exposed outside the outsole of the shoe. Moreover, the protective film 30 can be of various colors, so that after the upper side wall 21 of the second sole layer 20 is wrapped, a double-layered two-color shoe outsole structure is created. In addition, the second shoe bottom layer 20 is covered by the cover film 30 by the shoe side wall 21, and the material property of the film 30 is used to express a fine gloss surface effect.
