Description

Technical Field

[0001] The present application relates to the field of shoes and clothing, and in particular to a waterproof and breathable composite structure, a shoe upper, and a casual shoe. Background Art

[0002] The shoe upper of a shoe is generally formed by laminating multiple layers of materials to achieve the effects of protecting the feet, providing comfort, and being aesthetically pleasing.

[0003] The composite structure used in the existing shoe upper is generally composed of a mesh fabric and a foam. The foam is soft and elastic. After the mesh fabric and the foam form the shoe upper, the comfort of the shoe upper is high. The foam itself has many pores, but most of the pores inside the foam are separated from each other, and air is difficult to pass through the foam, thereby reducing the breathability of the composite structure. Summary of the Utility Model

[0004] In order to improve the breathability of the composite structure, the present application provides a waterproof and breathable composite structure, a shoe upper, and a casual shoe.

[0005] The waterproof and breathable composite structure, the shoe upper, and the casual shoe provided by the present application adopt the following technical solutions:

[0006] A waterproof and breathable composite structure includes a mesh fabric, a first foam, a first gauze, and a first waterproof and breathable membrane connected in sequence. The first foam is provided with a plurality of ventilation holes.

[0007] By adopting the above technical solutions, the ventilation holes allow air to pass through the first foam, thereby improving the breathability of the composite structure. At the same time, the first waterproof and breathable membrane allows water vapor and air to pass through, and can block water from passing through, so that the composite structure has good waterproof performance.

[0008] Optionally, both sides of the first foam are provided with a plurality of ventilation grooves, the ventilation grooves are arranged horizontally and vertically in a staggered manner, and some of the ventilation holes are located on the inner bottom wall of the ventilation grooves.

[0009] By adopting the above technical solutions, after the composite structure is made into a shoe upper, when the shoe upper contacts the foot, some of the ventilation holes are blocked, and there will also be some trademarks and patterns on the outer surface of the shoe upper, and the trademarks and patterns will also block the ventilation holes. After the ventilation holes are blocked, air enters the ventilation grooves, and then the air flows along the ventilation grooves and is discharged, thereby improving the breathability of the composite structure.

[0010] Optionally, the first foam is provided with a plurality of reinforcing tubes, the reinforcing tubes are fixedly installed inside the ventilation holes, and the number of the fixing tubes is less than or equal to the number of the ventilation holes.

[0011] By adopting the above technical solution, the composite structure is made into a shoe upper, and the shoe upper and the foot are mutually extruded, so that the ventilation holes are deformed and closed. The ventilation holes are kept open by the reinforcement tubes, thereby improving the ventilation performance of the composite structure. At the same time, by adjusting the number of reinforcement tubes, the hardness of the first foam can be adjusted, so as to conveniently adjust the hardness of the shoe upper, and further improve the comfort of wearing casual shoes.

[0012] Optionally, an extension part is fixedly installed at one end of the reinforcement tube close to the mesh fabric, and the extension part penetrates through the mesh fabric.

[0013] By adopting the above technical solution, the extension part increases the roughness of the first foam on the side close to the mesh fabric, thereby reducing the relative sliding between the first foam and the mesh fabric.

[0014] A shoe upper includes a shoe upper body and a tongue fixedly installed on the shoe upper body, and both the shoe upper body and the tongue are made of a waterproof and breathable composite structure of the present application.

[0015] By adopting the above technical solution, the composite structure of the present application has good waterproof and breathable performance, so that the shoe upper body and the tongue also have good waterproof and breathable performance.

[0016] A casual shoe includes a sole and a shoe upper fixedly installed on the sole, and the shoe upper adopts the above-mentioned shoe upper

[0017] By adopting the above technical solution, the shoe upper of the present application has good waterproof and breathable performance, so that the casual shoe also has good waterproof and breathable performance.

[0018] Optionally, fixing straps are fixedly installed on both sides of the tongue, the side of the fixing strap away from the tongue is fixedly connected to the top side of the sole, and the space between the two fixing straps is for the human foot to pass through.

[0019] By adopting the above technical solution, the fixing straps are used to fix the tongue and prevent the tongue from moving around. At the same time, the fixing straps also securely lock the foot in the shoe.

[0020] Optionally, the fixing strap includes a second gauze, a second foam and a second waterproof and breathable membrane. There are two second gauzes which are arranged oppositely, the second foam is installed between the two second gauzes, and the second gauze close to the shoe upper is fixedly connected to the second waterproof and breathable membrane.

[0021] By adopting the above technical solution, the second foam is soft and elastic, thereby improving the comfort when the foot contacts the fixing strap. When the first waterproof and breathable membrane cracks and is damaged, some water may flow into the casual shoe. The second waterproof and breathable membrane blocks the water entering the casual shoe, thereby reducing the situation that the fixing strap absorbs water and affects the comfort.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By providing air vents on the first foam for air circulation and using a waterproof and breathable membrane to block water passage, the waterproof and breathable performance of the composite structure is improved.

[0024] 2. By shaping the air vents with a fixing tube, the situation where the air vents are deformed and closed after the foam is squeezed is reduced, thereby improving the breathable performance of the composite mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 drawings.

[0031] Embodiment 1.

[0032] Embodiment 1 of the present application discloses a waterproof and breathable composite structure, a shoe upper and a casual shoe.

[0033] Referring to Figure 1 , a waterproof and breathable composite structure includes a mesh fabric 1, a first foam 2, a first gauze 3, and a first waterproof and breathable membrane 4 connected in sequence. The first foam 2 is provided with a plurality of air vents 5. The mesh fabric 1 and the first gauze 3 itself have holes for air passage, and the air vents 5 allow air to pass through the first foam 2, and then the first waterproof and breathable membrane 4 allows air and water vapor to pass through and blocks water passage, thereby improving the waterproof and breathable performance of the composite structure. The air vents 5 on the first foam 2 can use punching equipment, and the structure of the air vents 5 is simple, thus facilitating the production of the first foam 2 with air vents 5.

[0034] Referring to Figure 2 , OneA shoe upper, including a shoe upper body 6 and a tongue 7 fixedly installed on the shoe upper body 6. Both the shoe upper body 6 and the tongue 7 are made of a waterproof and breathable composite structure according to an embodiment of the present application, thereby improving the waterproof and breathable performance of the shoe upper.

[0035] In another embodiment, when the shoe upper body 6 is made using a composite mechanism, the ventilation holes 5 are densely arranged at the part where the shoe upper body 6 fits with the foot, thereby improving the ventilation performance of the shoe upper. At the part where the shoe upper body 6 is separated from the foot, the density of the ventilation holes 5 is small, thereby improving the waterproof performance of the shoe upper.

[0036] Refer to Figure 2 , A casual shoe, including a sole 8 and a shoe upper fixedly installed on the sole 8. The shoe upper adopts a shoe upper according to an embodiment of the present application.

[0037] Fixing straps 9 are fixedly installed on both sides of the tongue 7. The side of the fixing strap 9 away from the tongue 7 is fixedly connected to the top side of the sole 8. A space between the two fixing straps 9 is for a human foot to pass through.

[0038] The fixing strap 9 can fix the human foot inside the casual shoe, thereby improving the comfort of wearing the casual shoe. At the same time, the fixing strap 9 helps to keep the tongue 7 fixed, thereby reducing the occurrence of the tongue 7 shifting.

[0039] Refer to Figure 3 , The fixing strap 9 includes a second gauze 91, a second foam 92 and a second waterproof and breathable membrane 93. There are two second gauzes 91 and they are arranged oppositely. The second foam 92 is installed between the two second gauzes 91. The second gauze 91 close to the shoe upper is fixedly connected to the second waterproof and breathable membrane 93.

[0040] During the wearing process of the casual shoe, the casual shoe will gradually age, causing the first waterproof and breathable membrane 4 to leak. When part of the water enters the casual shoe due to the leakage of the first waterproof and breathable membrane 4, the second waterproof and breathable membrane 93 blocks it, thereby reducing the situation where the comfort is affected after the fixing strap 9 absorbs water.

[0041] The implementation principle of a waterproof and breathable composite structure, a shoe upper and a casual shoe according to an embodiment of the present application is as follows: By opening ventilation holes 5 on the first foam 2 for air to pass through, and then the first waterproof and breathable membrane 4 has the performance of stopping water and allowing air to pass through, thereby improving the waterproof and breathable performance of the composite structure.

[0042] Embodiment 2.

[0043] An embodiment of the present application discloses a waterproof and breathable composite structure, a shoe upper and a casual shoe.

[0044] Refer to Figure 4, A waterproof and breathable composite structure, in which a plurality of ventilation grooves 10 are formed on both sides of the first foam 2, and the ventilation grooves 10 are arranged in a crisscross pattern horizontally and vertically. After the ventilation grooves 10 are formed by cutting on both sides of the first foam 2, some ventilation holes 5 will be on the inner bottom wall of the ventilation grooves 10.

[0045] After the composite mechanism is made into a shoe upper, trademarks and patterns will be set on the outer surface of the shoe upper, thus blocking the ventilation holes 5. After the ventilation holes in the ventilation grooves 10 are blocked, air is discharged from the ventilation grooves 10, thereby improving the breathable performance of the composite structure.

[0046] The first foam 2 is provided with a plurality of reinforcing tubes 11, and the reinforcing tubes 11 are fixedly installed inside the ventilation holes 5. One end of the reinforcing tube 11 close to the mesh 1 is fixedly installed with an extension part 12, and the extension part 12 penetrates through the mesh 1. The number of the fixed tubes is less than or equal to the number of the ventilation holes 5.

[0047] When using a punching device to punch the first foam 2 to form ventilation holes 5, the punching part on the punching device will pass through the first foam 2 to form ventilation holes 5. If it is necessary to install the reinforcing tubes 11 inside the ventilation holes 5, the punching part is heated, and then the inner wall of the punching part comes into contact with the inner wall of the ventilation holes 5, and the inner wall of the punching part melts to form the reinforcing tubes 11. When the punching part is pulled out of the ventilation holes 5, the punching part remains heated. Then the punching part will bring out the melted part of the first foam 2 from the ventilation holes 5, thus forming the extension part 12.

[0048] If the extension part 12 is not needed, when the punching part is pulled out of the ventilation holes 5, let the reinforcing tubes 11 cool and solidify, and then pull out the punching part.

[0049] The implementation principle of a waterproof and breathable composite structure, a shoe upper and a casual shoe in an embodiment of the present application is that the reinforcing tubes 11 are beneficial to shaping the ventilation holes 5, thereby reducing the situation that the ventilation holes 5 are closed after the first foam 2 is squeezed, and further improving the breathable performance of the composite structure.

[0050] The more the number of the fixed tubes, the greater the hardness of the first foam 2. By adjusting the number of the fixed tubes, it is convenient to adjust the hardness of the composite structure. When wearing the casual shoes, the hardness of the composite structure is adjusted, thereby adjusting the hardness of the shoe upper, and further improving the comfort of wearing the casual shoes.

[0051] The extension part 12 is beneficial to increasing the roughness of the first foam 2 close to the mesh 1, thereby reducing the relative sliding between the mesh 1 and the first foam 2.

[0052] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
