Shoe with coated welt

Abstract

Provided is a shoe with a coated welt. The shoe comprises a shoe sole, a shoe upper arranged on the shoe sole, and a welt arranged between the shoe sole and the shoe upper, wherein the welt comprisesa welt body and a coated piece, the welt body is made from a thermoplastic material and prepared by a means of extrusion molding, the welt body is provided with a bottom surface corresponding to the shoe sole, a top surface opposite to the bottom surface, and an outer wall face and an inner wall face, the outer wall face and the inner wall face are connected to the portion between the bottom surface and the top surface and oppositely arranged, the inner wall face is opposite to the shoe upper, the coated piece is arranged on the welt body and at least fully coats the top surface and the outerwall face, the coated piece is flexible, and comprises at least one coating layer and an explicit pattern, the coating layer is made from different materials of the welt body, the explicit pattern isformed on the coating layer and arranged opposite to at least one of the top surface and the outer wall face, and the coating piece is not a successive extension structure of any one of the shoe sole,the shoe upper and the welt body.

Description

technical field [0001] The invention relates to a shoe, in particular to a shoe with a covered welt. Background technique [0002] In the production of shoe welts, it is generally made by plastic extrusion molding. Depending on the machine, single-color or multi-color welts can be produced. However, refer to figure 1 and figure 2 , the above-mentioned multi-color welt 1 passes through several along the longitudinal direction (see figure 1 ) or landscape (see figure 2 ) stacked together and respectively have different colors of welt assembly 11 to achieve the appeal of multi-color appearance, the welt assembly 11 extends along the extension direction of the welt 1 . Since the molding thickness and shape of each welt assembly 11 is limited due to the extrusion molding method and the overall shape of the welt 1, the welt assembly 11 is used as the main appearance part of the welt 1 On a top surface 12 and an outer wall surface 13, the change of color patterns presented is...

AI Technical Summary

Problems solved by technology

Since the molding thickness and shape of each welt assembly 11 is limited due to the extrusion molding method and the overall shape of the welt 1, the welt assembly 11 is used as the main appearance part of the welt 1 On a top surface 12 and an outer wall surface 13, the change of color patterns presented is also limited, and it is difficult to adjust the welt 1 to produce different appearance color pattern changes in accordance with different appearance designs of shoes. Although the general welt can be printed on the surface to form a decorative pattern, but the shape of the welt is three-dimensional and varied, generally not suitable for direct printing, and the quality of printing is difficult to control and the surface texture of the welt cannot be effectively improved, so it is difficult to meet consumer demand. expectations

[0003] Furthermore, although the U.S. patents US6,978,560 and US7,003,902 mention using an upper or a wrapping sheet to wrap an interior strip to form an edge, however , the US6,978,560 case because the production of the welt needs to be combined with the shoe upper, so it is not easy to implement, and it is difficult to use the commercially available welt product as the rod for the production of the welt; in addition, the US7,003,902 case The covering material of the welt has a marginal portion arranged between the upper and the sole. The marginal portion is superimposed with the upper and lower double-layer structures. After superposition, the thickness of the marginal portion will increase. Therefore, its The disadvantage is that during the actual manufacturing process of the shoes, the edge of the welt is prone to wrinkle, which affects the bonding strength between the welt and the upper. Furthermore, the edge of the welt will add additional material cost, especially when the cladding is leather
