Description

Technical Field

[0001] This utility model relates to the field of footwear technology, specifically to a type of footwear. Background Technology

[0002] The design and manufacture of shoes involves multiple stages, among which the connection between the upper and the sole is one of the most critical. Uppers are typically made of materials such as leather, synthetic fibers, and mesh, while soles are mostly made of materials like rubber and polyurethane. To ensure the comfort and durability of the shoes, the connection between the upper and the sole needs to be strong and have sufficient tensile strength.

[0003] To enhance the visual appeal of shoes, offset printing technology is often used for upper design, printing patterns or logos onto the shoe surface to provide a rich visual effect. However, the presence of the offset printing layer may affect the bonding strength at the joints. Currently, the connection between the upper and the sole is usually glued, but the adhesion between the sole and the offset printing layer is poor, resulting in reduced tensile strength at the joint and making it prone to separation during use. Utility Model Content

[0004] The purpose of this invention is to provide a shoe that improves the problem of existing shoes being prone to coming apart.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A type of shoe, comprising:

[0007] The sole includes a sole body and sidewalls extending upwards and disposed around the periphery of the sole body; and

[0008] The shoe upper has an adhesive layer on its outer side and a bonding portion that is bonded to the side wall. The adhesive layer corresponding to the bonding portion has a connection structure that allows adhesive to pass through the adhesive layer to connect the bonding portion and the side wall respectively.

[0009] In this invention, the adhesive can connect the bonding part of the shoe upper to the side wall of the sole through the connecting structure. This is equivalent to the side wall being glued to both the adhesive layer and the bonding part, thereby improving the connection strength, enhancing the tensile strength at the connection point, preventing delamination, and improving the overall durability of the shoe.

[0010] Preferably, the connection structure consists of a plurality of through holes for bonding disposed on the adhesive layer corresponding to the bonding portion.

[0011] In this invention, multiple through holes are provided on the adhesive layer located between the upper and the sole. The adhesive can pass through the through holes to connect the bonding part of the upper to the side wall of the sole. This is equivalent to the side wall being bonded to both the adhesive layer and the bonding part, thereby improving the connection strength, enhancing the tensile strength at the connection point, preventing delamination, and improving the overall durability of the shoe.

[0012] Preferably, a blank area without the adhesive layer is provided on the lower side of the bonding portion of the shoe upper, and the blank area is located between the bonding portion and the bottom surface where the shoe upper and the sole body are connected.

[0013] Preferably, the width of the blank area is 3 to 10 mm.

[0014] Preferably, the through hole is a circular hole, an elliptical hole, a rhomboid hole, or a rectangular hole; or, the through hole is a mesh-like hole or a honeycomb-like hole.

[0015] Preferably, the plurality of through holes are distributed at equal intervals, or the distribution density of the through holes gradually decreases from the bottom edge of the mating portion upwards.

[0016] Preferably, the width of the bonding portion is 3 to 10 mm.

[0017] Preferably, the width of the bonding portion is 8mm.

[0018] Preferably, the cross-sectional area of ​​the through hole is larger the closer it is to the blank area.

[0030] Example

[0031] Please refer to Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a shoe, including a sole 10 and an upper 11. The upper is typically made of materials such as leather, synthetic fibers, or mesh, while the sole is mostly made of materials such as rubber or polyurethane. The sole 10 has upwardly extending sidewalls 101 (defined as upward along the horizontal plane); the outer surface of the upper 11 has a printed layer 111 (defined as the side in contact with the foot as the inner side and the side away from the inner side as the outer side). The upper 11 has a bonding portion 112 that adheres to the sidewalls 101. The printed layer 111 corresponding to the bonding portion 112 has a connection structure that allows adhesive to pass through the printed layer 111 to connect the bonding portion 112 and the sidewalls 101. The connection structure consists of multiple through holes 1121 for bonding on the printed layer 111 corresponding to the bonding portion 112. Specifically, the printed layer 111 is a coating of patterns, text, or other design elements printed on the outer surface of the upper 11 using offset printing technology. The bonding portion 112 of the upper 11 is adhesively bonded to the sidewall 101 of the sole 10. Since the presence of the adhesive layer 111 affects the bonding strength (the surface of the adhesive layer 111 is relatively smooth, resulting in poor adhesion to the sidewall 101), multiple through holes 1121 are provided on the adhesive layer 111 at the bonding portion 112. Adhesive can pass through the through holes 1121 to connect the bonding portion 112 to the sidewall 101, effectively bonding both the sidewall 101 to the adhesive layer 111 and the bonding portion 112, thus enhancing the bonding strength. Furthermore, the upper 11 can be a mesh upper, nylon upper, or knitted upper, with a relatively rough surface, which effectively increases the adhesion of the adhesive, thereby improving the connection strength, enhancing the tensile strength at the connection point between the upper 11 and the sole 10, preventing delamination, and improving the overall durability of the shoe.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, a blank area 113 without an adhesive layer 111 is provided on the lower side of the bonding portion 112 of the upper 11. The blank area 113 is located between the bonding portion 112 and the bottom surface where the upper 11 connects to the sole body. That is, a portion of the bottom edge of the upper 11 is left untreated with adhesive, preserving the rough surface characteristics of the upper 11, which helps in the adhesive bonding between the upper 11 and the sole 10, further enhancing the strength of the connection. The width of the blank area 113 is 3–10 mm. In a preferred embodiment, the width of the blank area 113 is 8 mm to ensure that the upper 11 has a sufficiently rough surface for adhesive adhesion, improving the adhesive bonding effect between the upper 11 and the sole 10 and preventing delamination.

[0033] In this embodiment, the through-hole 1121 is a circular hole, an elliptical hole, a rhomboid hole, or a rectangular hole, or a mesh-like hole or a honeycomb-like hole. Furthermore, multiple through-holes 1121 are distributed at equal intervals to ensure that the adhesive is evenly distributed on the bonding portion 112; or, the distribution density of the through-holes 1121 gradually decreases from the bottom edge of the bonding portion 112 upwards, meaning that the through-holes 1121 are more densely distributed near the bottom edge of the bonding portion 112, resulting in more adhesive used in that area and a stronger bond. As the distribution of the through-holes 1121 gradually thins upwards, the bond strength gradually transitions, and relatively less adhesive is applied to the top edge of the bonding portion 112, avoiding adhesive overflow and ensuring that the connection between the upper 11 and the sole 10 is both strong and aesthetically pleasing.

[0034] In this embodiment, the width of the bonding portion 112 is 3 to 10 mm. In a preferred embodiment, the width of the bonding portion 112 is 8 mm to ensure that the adhesive area between the bonding portion 112 and the side wall 101 is sufficient.

[0035] In this embodiment, the cross-sectional area of ​​the through hole 1121 is larger the closer it is to the blank area 113. Therefore, the adhesive distribution area is larger the closer it is to the blank area 113. The adhesive connects the bonding part 112 and the side wall 101 through the through hole 1121, thereby forming a stronger bonding effect in this area and effectively preventing the shoe upper 11 from delaminating with the shoe sole 10.

[0036] 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.
