Description

Technical Field

[0001] This utility model relates to the field of women's shoe technology, specifically to a women's shoe with an anti-cracking upper. Background Technology

[0002] Women's shoes are an indispensable part of daily use. Most of the existing women's shoes have curved uppers, which are located at the front, while the back is relatively high. This causes the front to bend under the pressure of walking, which increases the probability of the upper cracking under pressure.

[0003] A search revealed that patent application number 201620406202.0 discloses a crack-resistant shoe upper, comprising a shoe upper substrate layer, a flax fiber layer bonded to the lower surface of the substrate layer, a printed surface layer bonded to the upper surface of the substrate layer, a fiberglass mesh layer bonded between the substrate layer and the printed surface layer by an adhesive, a crack-resistant coating layer coated on the upper surface of the printed surface layer, and a polytetrafluoroethylene (PTFE) film layer bonded to the upper surface of the crack-resistant coating layer. This invention utilizes fiberglass material with excellent mechanical strength, reducing the impact of surface shear stress on the shoe upper and making it less prone to cracking. Furthermore, the crack-resistant coating possesses good toughness, further reducing the likelihood of cracks under thermal expansion and contraction. Simultaneously, PTFE exhibits excellent overall strength, further enhancing the crack-resistant performance of the shoe upper surface, and also possesses high lubricity and non-stickiness, making the shoe upper less susceptible to staining.

[0004] The aforementioned application documents achieve the effect of preventing cracking through the setting of various materials, but the method used is to add top surface material, which does not substantially increase the compressive strength, resulting in limited compressive strength of the shoe upper when applied to women's shoes.

[0005] Therefore, we propose a women's shoe with an anti-cracking upper. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a women's shoe with an anti-cracking upper, solving the problem that existing shoe uppers do not have an anti-compression component added from the inside, resulting in limited overall compressive strength and easy cracking.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a women's shoe with an anti-cracking upper, including an upper part and a shoe collar part on the rear side, and a shoe heel part is fitted at the bottom of the shoe collar part;

[0008] The main body of the shoe upper consists of a shoe upper substrate layer and a shoe shield shell. A polytetrafluoroethylene film layer is glued to the top of the shoe upper substrate layer, and a printed surface layer is also glued to the top of the polytetrafluoroethylene film layer.

[0009] The bottom of the shoe shield shell is fitted with a layer of flax fibers.

[0010] As a preferred embodiment of the present invention, the polytetrafluoroethylene film layer and the printed surface layer are bonded together by an upper glass fiber mesh layer and an adhesive.

[0011] The upper fiberglass mesh layer can be glued to the top of the shoe upper substrate layer from the top side. With the outer mesh layer, the outer polytetrafluoroethylene film layer and the printed surface layer can be attached, increasing the overall adhesion and laying effect, assembling them into one piece, thereby increasing the tensile strength.

[0012] As a preferred embodiment of this utility model, the bottom surface of the shoe shield shell and the flax fiber layer are bonded together by a lower glass fiber mesh layer and an adhesive.

[0013] The lower fiberglass mesh layer allows the flax fiber layer to be assembled on the inside of the shoe shield shell from the inside, further enhancing its tensile and compressive strength from the inside and preventing cracking on the inside.

[0014] As a preferred embodiment of this utility model, the upper substrate layer is adhered to the shoe shield shell, and the shoe shield shell is a toe shell that is adapted to the overall shape and curvature of the upper part of the shoe.

[0015] The design of the shoe shield shape allows it to fit the outer upper substrate layer, ensuring that the entire upper part of the shoe is fitted to the front of the shoe collar, thus guaranteeing a seamless and aesthetically pleasing appearance.

[0016] As a preferred embodiment of this utility model, the shoe shield shell is composed of an inner thermoplastic polyurethane elastomer and a silicone layer wrapped around it on the outside.

[0017] The material of the shoe shield shell is designed to quickly return to its original position after being deformed under pressure, ensuring pressure resistance.

[0018] This utility model provides a women's shoe with an anti-cracking upper. It has the following beneficial effects:

[0019] This women's shoe with an anti-cracking upper utilizes a shoe shield shell as the main component, with various layers of materials attached to it by upper fiberglass mesh layers and printed surface layers on both sides of the top and bottom. This prevents cracking from the outside. The shoe shield shell and the upper base material layer increase the overall elasticity and allow it to quickly return to its original position after deformation, increasing the compressive and tensile strength and reducing the probability of cracking in the upper. This solves the problem of limited overall compressive strength and easy cracking in existing shoe uppers due to the lack of compressive components on the inside. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a women's shoe with an anti-cracking upper, including an upper part 1 and a shoe upper part 2 on the rear side, and a shoe heel part 3 is assembled at the bottom of the shoe upper part 2; the main body of the upper part 1 is an upper substrate layer 11 and a shoe shield shell 12, a polytetrafluoroethylene film layer 14 is glued to the top of the upper substrate layer 11, and a printed surface layer 16 is also glued to the top of the polytetrafluoroethylene film layer 14; a flax fiber layer 13 is glued to the bottom of the shoe shield shell 12;

[0026] Among them, the women's shoe with anti-cracking upper, through the setting of various components in the upper 1, can use the shoe shield shell 12 as the main component, and the upper glass fiber mesh layer 15 and printed surface layer 16 on the top and bottom sides are attached to the various layers of materials, which can prevent the shoe from cracking from the outside. The setting of the shoe shield shell 12 and the upper base material layer 11 on it can increase its overall elasticity and can quickly return to its original position after deformation, increasing the pressure resistance and tensile strength, reducing the probability of cracking of the upper 1, and solving the problem that the existing upper 1 does not have an anti-pressure component added from the inside, resulting in limited overall pressure resistance and easy cracking. Example 1:

[0027] The polytetrafluoroethylene film layer 14 and the printed surface layer 16 are bonded together by an upper glass fiber mesh layer 15 and an adhesive. The upper glass fiber mesh layer 15 can be bonded to the top of the shoe upper substrate layer 11 from the top side. By utilizing its outer mesh layer, the outer polytetrafluoroethylene film layer 14 and the printed surface layer 16 can be attached, increasing the overall adhesion and laying effect, assembling them into one piece, thereby increasing the tensile strength.

[0028] The bottom surface of the shoe shield shell 12 and the flax fiber layer 13 are bonded together with adhesive through a lower glass fiber mesh layer 17; wherein, the lower glass fiber mesh layer 17 can assemble the flax fiber layer 13 on the inner side of the shoe shield shell 12 from the inside, and further enhances its tensile and compressive strength from the inside, preventing cracking on the inside.

[0029] The upper substrate layer 11 is adhered to the shoe shield shell 12, and the shoe shield shell 12 is a toe shell that matches the overall shape and curvature of the upper 1. The shape of the shoe shield shell 12 can be adapted to the outer side of the upper substrate layer 11 to ensure that the upper 1 is fully assembled on the front side of the upper 2, thus ensuring its integrated aesthetic effect.

[0030] The shoe shield shell 12 is composed of an inner thermoplastic polyurethane elastomer and a silicone layer wrapped around it on the outside; the material of the shoe shield shell 12 can quickly return to its original position after being deformed under pressure, ensuring pressure resistance.

[0031] The working principle and usage process of this utility model are as follows: The upper substrate layer 11 is bonded to the shoe shield shell 12. Then, a polytetrafluoroethylene film layer 14 is bonded to the top side of the upper substrate layer 11. An upper glass fiber mesh layer 15 is wrapped around the top side of the polytetrafluoroethylene film layer 14. A printed surface layer 16 is also bonded to the top side of the polytetrafluoroethylene film layer 14 and the upper glass fiber mesh layer 15 by adhesive. At the same time, a lower glass fiber mesh layer 17 is bonded to the inner side of the shoe shield shell 12. Then, a flax fiber layer 13 is bonded to the innermost side. The upper glass fiber mesh layer 15 and the lower glass fiber mesh layer 17 ensure tensile strength from both the inside and outside. At the same time, the increased compressive strength and recovery ability of the shoe shield shell 12 can fundamentally prevent it from cracking.
