Description

Technical Field

[0001] This utility model relates to the field of footwear, specifically to a shoe front structure, shoe upper, and shoe. Background Technology

[0002] When manufacturing shoe uppers, one of the processes involved in designing the toe structure is hot pressing, followed by rapid sewing of the upper fabric. This leaves little time for operators, leading to tight schedules and high labor intensity on assembly lines. This process is necessary to shape the upper and prevent wrinkles from forming at the toe due to thermal expansion and contraction, which would affect the quality of the toe construction. Furthermore, a toe-setting machine is required to maintain the three-dimensional shape of the toe, adding to the operational steps and increasing costs. Utility Model Content

[0003] The purpose of this invention is to provide a shoe toe structure, shoe upper, and shoe, which aims to improve the existing shoe toe manufacturing process, which requires shaping and sewing to be completed in a short time, resulting in low production efficiency and flexibility.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a shoe front piece structure, comprising:

[0005] The upper layer has a first notch at the toe for forming a flat curved surface when it is made into a toe;

[0006] A first adhesive film is disposed on the outer surface of the surface layer and covers the first notch; and

[0007] An inner layer is disposed on the inner surface of the outer layer and covers the first notch. A second adhesive film is disposed between the inner layer and the inner surface of the outer layer. The second adhesive film is provided with a second notch that overlaps and aligns with the first notch, so that the first adhesive film is bonded to the inner layer through the second notch.

[0008] As a preferred structure of this utility model, the first notch is two arc-shaped segments, a semi-elliptical shape, or a triangular shape arranged symmetrically on the axis.

[0009] As a preferred structure of this utility model, the surface layer is a mesh structure.

[0010] As a preferred structure of this utility model, the edge formed by the first adhesive film and the inner layer covering the first gap is aligned with the edge of the surface layer, forming the sewing area of ​​the tufting fabric.

[0011] As a preferred structure of this utility model, the toe is provided with a stitching structure for sewing together the surface layer, the first adhesive film, the inner layer and the second adhesive film.

[0012] As a preferred structure of this utility model, one side of the first adhesive film is a smooth surface and the other side is an adhesive surface.

[0013] This disclosure also provides a shoe upper, including the forefoot structure as described above.

[0014] This disclosure also includes a shoe comprising the forefoot structure as described above.

[0015] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] 1. This utility model designs a notch in the surface layer, then adheres and bonds it to the outer surface of the surface layer using a first adhesive film, and the inner layer is bonded using a second adhesive film. The notch is then re-bonded, eliminating the need for a complete shoe toe structure. This allows for storage and flexible design of the next production step after hot-press bonding. Furthermore, the notch design prevents wrinkles during bending and fabrication of the shoe toe structure, resulting in efficient and high-quality production. Attached Figure Description

[0033] Example 1

[0034] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a shoe toe structure, including an outer layer 10, a first adhesive film 20, and an inner layer 30. The toe portion 1 of the outer layer 10 is provided with a first notch 101 for forming a flat curved surface when the toe 1 is made. The first adhesive film 20 is disposed on the outer surface of the outer layer 10 and covers the first notch 101. The inner layer 30 is disposed on the inner surface of the outer layer 10 and covers the first notch 101. A second adhesive film 40 is disposed between the inner layer 30 and the inner surface of the outer layer 10. The second adhesive film 40 is provided with a second notch 401 that overlaps and aligns with the first notch 101, so that the first adhesive film 20 is bonded to the inner layer 30 through the second notch 401.

[0035] The shoe forefoot structure disclosed herein is a structure corresponding to the forefoot position of the shoe upper. The shoe forefoot structure can be an independent forefoot part or an integral shoe piece structure (including the heel piece).

[0036] In this disclosure, the first adhesive film 20 can be a protective film, meaning one side of the first adhesive film 20 is smooth and the other side is an adhesive surface, used for bonding. Alternatively, the stability of the bond can be improved by hot-melt bonding. The second adhesive film 40 can be a hot-melt film, used for bonding by hot pressing to achieve the bonding purpose.

[0037] Furthermore, such as Figure 5 and Figure 6 As shown, this disclosure provides a stitching structure 2 on the toe 1 to sew together the surface layer 10, the first adhesive film 20, the inner layer 30, and the second adhesive film 40. That is, after the heat-pressing bonding is completed, the toe 1 is sewn together by stitching to improve the stability of the toe 1 structure.

[0038] During manufacturing, the first adhesive film 20, the surface layer 10, the second adhesive film 40, and the inner layer 30 are stacked sequentially from top to bottom, such that the first notch 101 of the surface layer 10 and the second notch 401 of the second adhesive film 40 are stacked and aligned, so that the first adhesive film 20 can pass through the two notches and bond with the inner layer 30, while other areas of the inner layer 30 are bonded to the surface layer 10 through the second adhesive film 40.

[0039] The first notch 101 of this disclosure is symmetrically arranged as two arc-shaped segments, a semi-elliptical shape, or a triangle, etc. The second notch 401 has the same outline or shape as the first notch 101, preferably a semi-elliptical notch structure. The notch design eliminates wrinkles that occur after the toe area 1 is bent and shaped. Different notch shapes help adapt to different shoe shapes; for example, shoes with a wider toe 1 can use symmetrically arranged two arc-shaped segments or a semi-elliptical notch, while shoes with a pointed toe 1 can use a triangular notch, thus ensuring the smoothness and comfort of the toe 1 after molding.

[0040] The surface layer 10 of this disclosure has a mesh structure, such as a large mesh or a small mesh structure, preferably a large mesh structure, to enhance the breathability and softness of the toe 1. Furthermore, the first adhesive film 20 and the second adhesive film 40 are used for bonding at the notch area and do not affect the overall breathability of the toe 1.

[0041] like Figure 5 As shown, the first adhesive film 20 and the inner layer 30 cover the edge formed by the first notch 101 and are aligned with the edge of the surface layer 10 to form the sewing area 102 of the tufting fabric 3.

[0042] Specifically, after the first notch 101 on the opposite layer 10 is heat-fused (heat-fusion bonding can be performed directly on the plane without the need for heat-pressing and shaping using the toe-shaped machine 1), the upper is then sewn together using the lasting fabric 3 to form the upper structure. For the parallel heat-pressed toe panel structure, the edges remain neat and wrinkle-free for a long time, and it will not deform due to thermal expansion and contraction. Therefore, there is no need to complete sewing and heat-pressing in a short time for subsequent lasting, allowing for flexible production arrangements and improving production flexibility and practicality.

[0043] Example 2

[0044] like Figure 5 and Figure 6 As shown, this embodiment provides a shoe upper, including a forefoot structure as described in Embodiment 1. The forefoot and heel pieces can be sewn and / or glued together, or the forefoot structure can have an integrally formed heel piece, and then subjected to overall heat pressing to form a complete upper structure. Subsequently, the upper fabric 3 is sewn together. This yields a finished shoe upper, which is then glued and sewn to the sole to obtain the desired shoe.

[0045] Example 3

[0046] This embodiment provides a shoe, including a forefoot structure as described in Embodiment 1. The design of the forefoot structure ensures that the toe area 1 is wrinkle-free during bending and shaping, guaranteeing efficient and high-quality upper production. Different upper materials or structures can then be combined to form different upper structures, such as mesh or leather, resulting in various upper designs. These, in turn, can be combined with different sole designs, such as rubber or foam soles, to meet diverse market demands.

[0047] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
