Description

TECHNICAL FIELD

[0001] The utility model relates to the field of shoes. BACKGROUND

[0002] The upper is made of leather material, PU leather and synthetic leather, and the sole is made of rubber and TPR material. The upper and the sole are prone to delamination. The reason is that the surface of the upper made of leather, PU leather and synthetic leather is rough, and the bonding part of the upper and the sole is not completely dense, which may have small gaps, and water may enter the gaps, and the bonding part may be easily separated after water enters.

[0003] In order to make the upper and the sole more firmly connected, the upper is usually extended into the midsole and the outsole, and is clamped by the midsole and the outsole to increase the firmness. Alternatively, the upper is extended and wrapped to the bottom of the sole to increase the firmness. The above two structures not only increase the amount of the upper and the production cost, but also still have the problem of delamination. SUMMARY

[0004] In view of the technical problems in the background art, the technical problem to be solved by the utility model is to provide a shoe which is not prone to delamination and has a long service life.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: the shoe comprises a sole, a medium layer and an upper,

[0006] The medium layer is sheet-shaped and has a first surface and a second surface. The second surface of the medium layer is smooth. The first surface of the medium layer is attached to the inner surface of the upper. The connecting part of the upper and the side surface of the sole is sewn to the medium layer. The second surface of the medium layer is attached to the side surface of the sole.

[0007] The upper of the utility model is attached to the sole through the medium layer. The smooth surface of the medium layer is closely attached to the side surface of the sole, and the air between the two is discharged. The two are firmly attached, and it is difficult for water to enter between the medium layer and the side surface of the sole, so that the medium layer and the sole are not prone to delamination, and the shoe has a longer service life.

[0008] Preferably, the medium layer is made of TPU or PVC material.

[0009] Preferably, the sole is made of any one of TPR, PVC, PU, TPU, rubber and EV foam. The medium layer and the sole are attached by glue, and the attachment surfaces of the two are combined to form a firm bonding force.

[0010] Preferably, the part of the side surface of the sole attached to the medium layer is recessed inward and forms a receiving groove. The medium layer is matched with the shape of the receiving groove, and the medium layer is placed in the receiving groove. The setting of the receiving groove not only makes the appearance more beautiful, but also makes the positioning of the medium layer in the receiving groove more accurate, and the attachment processing is more convenient.

[0011] As a preferred manufacturing method, the upper is first sewn to the interlayer, and then adhesive is applied to the interlayer and / or the side of the sole. After adhesive application, the interlayer and the side of the sole are tightly bonded together, and air between them is expelled. This process is simple, uses less upper material, and results in better shoe quality. Attached Figure Description

[0015] The following describes the embodiments and related details and working principles of this utility model with reference to the accompanying drawings. This type of shoe includes a sole 5, a medium layer 2, and an upper 1. The upper 1 is made of leather. The medium layer 2 is sheet-like, having a first side and a second side. The second side of the medium layer 2 is smooth and is made of TPU or PVC. The sole 5 is made of any one of TPR, PVC, PU, ​​TPU, rubber, or EV foam. The first side of the medium layer 2 is bonded to the inner surface of the upper 1, and the connecting part 3 between the upper 1 and the side of the sole 4 is sewn to the medium layer 2, forming a physical connection between the upper and the medium layer. The second side of the medium layer 2 is bonded to the side of the sole 4, and the bonding surfaces of the medium layer and the sole fuse together, forming a strong bond, ultimately ensuring a firm connection between the upper and the insole.

[0016] To make the shoes more aesthetically pleasing, the part of the sole side 4 that is bonded to the medium layer 2 is recessed inward to form a receiving groove 6. The shape of the medium layer 2 matches that of the receiving groove 6, and the medium layer 2 is placed inside the receiving groove 6. The medium layer 2 is essentially hidden inside the receiving groove 6, so there is no feeling of thickening. Moreover, the medium layer 2 is positioned more accurately in the receiving groove 6, and the bonding process is also more convenient. Figure 2 In the middle, the connecting part 3 of the medium layer 2 and the upper 1 is placed in the receiving groove 6, so that the outer surface of the upper 1 is flush with the side of the sole 4.

[0017] The working principle of the preferred embodiment is further explained below with reference to the accompanying drawings. The upper is made of leather, the sole is made of TRP, and the medium layer is made of TPU. During manufacturing, the upper 1 is first sewn to the medium layer 2. Then, the medium layer 2 and / or the side of the sole 4 are evenly coated with adhesive. After the adhesive is applied, the medium layer 2 and the side of the sole 4 are tightly bonded together, and the air between them is expelled. At the same time, the bonding surfaces of the medium layer and the sole will fuse together, making the medium layer 2 firmly bonded to the sole 5.

[0018] This invention is not only easy to manufacture, but also uses less upper 1 and produces better quality shoes. The upper 1 is firmly sewn to the medium layer 2, and the rough surface of the upper 1 will not affect its sewing connection with the medium layer 2, and it will not come off when wet; the smooth surface of the medium layer 2 is bonded to the side of the sole 4, expelling the air between them, so that the two are tightly bonded and fused together. This kind of bonding is strong and will not come off when wet, resulting in a longer service life for the shoes.
