Description

Technical Field

[0001] The utility model specifically relates to the technical field of shoes, and particularly to a rear upper piece of shoes made of polymer materials. Background Art

[0002] Sports shoes are a type of footwear specifically designed for various sports activities, which play roles such as protecting the feet, providing comfort, and enhancing sports performance. The design and materials of sports shoes vary according to the type of sport and the needs of users. For example, running shoes, basketball shoes, football shoes, etc., are designed to provide the best support and protection. Modern sports shoes usually also have the characteristics of fashion and personalization to meet the needs and tastes of different consumers.

[0003] In the rear upper piece of traditional sports shoes, a foam layer is provided at the counter edge, and then a knitted fabric is provided on the inner side of the foam layer; due to the characteristics that the foam itself is not wear-resistant and not tear-resistant, it cannot be used alone in the exposed part and can only be padded inside the lining to increase comfort; most knitted fabrics are Tricot; Tricot is a very thin knitted fabric, mainly used as the lining after being bonded with the foam layer, but its strength is poor; the continuous process of putting on and taking off shoes will accelerate the damage of the knitted fabric. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rear upper piece of shoes made of polymer materials, in which a sponge layer and a PU layer are provided at the counter edge. The sponge layer is used to increase the comfort of the shoes, and the PU layer improves the smoothness when the user puts on and takes off shoes. Moreover, the PU layer has a soft texture, making the user feel more comfortable; and the fabric layer is made of fibers in polymer materials; this improves the structural strength and wear resistance of the outer surface of the rear upper piece; to solve the technical problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A rear upper piece of shoes made of polymer materials, including a lining layer, in which a gauze layer and a sponge layer are provided on the inner side of the lining layer; a PU layer is provided on the inner side of the sponge layer; the PU layer is connected to a fabric layer, and the fabric layer is located on the outer side of the lining layer.

[0007] As a further technical solution of the present invention, the lining layer is arranged in an "I" shape; the gauze layer has the same shape as the lining layer, and the gauze layer is adhesively fixed to the lining layer.

[0008] As a further technical solution of the present invention, the upper edge and the lower edge of the gauze layer and the lining layer are both arranged in an arc shape.

[0009] As a further technical solution of the present invention, the sponge layer is arranged in a trapezoidal shape and is adhesively fixed to the gauze layer.

[0010] As a further technical solution of the present invention, the PU layer is connected to the fabric layer by quilting.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model increases the comfort of the shoes through the sponge layer, and the PU layer improves the smoothness of the user when putting on and taking off the shoes. The PU layer is soft in texture, making the user more comfortable to wear. The fabric layer is made of fibers from polymer materials, which improves the structural strength and wear resistance of the rear upper surface.

[0013] 2. The utility model adopts PVC plastic material, which is a polymer material, as the inner lining layer. The inner lining layer increases the overall straightness of the rear upper piece, and the overall collapse of the rear upper piece will not occur due to wearing and taking off shoes.

[0014] 3. In the utility model, the upper and lower edges of the gauze layer and the inner lining layer are both arranged in an arc shape; when the rear upper piece is bent as a whole into a U-shape, it can be better fitted and quilted with the sole. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4, in the embodiment of the present utility model, a rear upper piece of a polymer material shoe includes a lining layer 2, and a gauze layer 3 and a sponge layer 4 are arranged on the inner side of the lining layer 2; a PU layer 5 is arranged on the inner side of the sponge layer 4; the PU layer 5 is connected to a fabric layer 1, wherein the fabric layer 1 is located on the outer side of the lining layer 2; the PU layer 5 and the fabric layer 1 are connected by quilting.

[0022] Specifically, the lining layer 2 includes side ears arranged on both sides, and the lining layer 2 is arranged in an "I" shape; the gauze layer 3 has the same shape as the lining layer 2, and the gauze layer 3 is fixedly bonded to the lining layer 2.

[0023] By adopting the above technical solution, when manufacturing the rear upper piece, first apply glue on the inner side of the lining layer 2 and bond the gauze layer 3 thereto; then bond the sponge layer 4 on the inner side of the gauze layer 3; subsequently, connect the PU layer 5 and the fabric layer 1 by quilting, bond the fabric layer 1 to the outside of the lining layer 2, fold the side ears of the lining layer 2 and the fabric layer 1 inward to wrap and fix the sponge layer 4, then fold the PU layer 5 upward and bond it to the inner side of the sponge layer 4; finally, quilt the remaining three sides of the PU layer 5 and the fabric layer 1 to form the rear upper piece of the shoe.

[0024] Furthermore, the lining layer 2 is made of PVC plastic material in the polymer material. Through the setting of the lining layer 2, the overall straight shape of the rear upper piece is increased, and the situation that the rear upper piece collapses as a whole due to wearing and taking off shoes will not occur.

[0025] In this embodiment, the upper edge and the lower edge of the gauze layer 3 and the lining layer 2 are both arranged in an arc shape.

[0026] By adopting the above technical solution, the setting of the arc-shaped edge can better fit and quilt with the sole when the rear upper piece is bent into a U shape as a whole.

[0027] In this embodiment, the sponge layer 4 is arranged in a trapezoidal shape and is fixedly bonded to the gauze layer 3.

[0028] The working principle of the present utility model is: when manufacturing the rear upper piece, first apply glue on the inner side of the lining layer 2 and bond the gauze layer 3 thereto; then bond the sponge layer 4 on the inner side of the gauze layer 3; subsequently, connect the PU layer 5 and the fabric layer 1 by quilting, bond the fabric layer 1 to the outside of the lining layer 2, fold the side ears of the lining layer 2 and the fabric layer 1 inward to wrap and fix the sponge layer 4, then fold the PU layer 5 upward and bond it to the inner side of the sponge layer 4; finally, quilt the remaining three sides of the PU layer 5 and the fabric layer 1 to form the rear upper piece of the shoe.
