Description

Technical Field

[0001] The present application relates to the field of shoe components, and in particular to a non-slip breathable rear shoe body. Background Art

[0002] The back of the shoe is the key part of the shoe that covers the heel and extends to the inner and outer waist. However, due to structural or material reasons, the back of the shoe is easily lifted up during wearing, causing the shoe to separate from the foot, and then causing the heel to fall off, which seriously affects the wearing comfort and the use effect of the shoe.

[0003] Currently, the rear shoe body is formed by heat pressing multiple layers of foam, and the inner side of the rear shoe body is provided with an ergonomic heel groove that conforms to the human foot, making it more comfortable to wear and having an anti-slip effect, thereby reducing the phenomenon of heels falling off when wearing sports shoes. However, due to the setting of the heel groove, the overall rear shoe body is closer to the foot, thereby hindering the air circulation inside the shoe, and making it easier to feel stuffy when wearing the shoe. Therefore, how to improve the air permeability of the rear shoe body while ensuring anti-slip properties has become a problem that needs to be urgently solved in the current field of footwear product design. Utility Model Content

[0004] In order to obtain a rear shoe body that has both good air permeability and good anti-slip properties, the present application provides an anti-slip and breathable rear shoe body.

[0005] The present application provides a non-slip and breathable rear shoe body, including a main body, an inner surface of the main body is provided with a heel groove, and the main body is provided with a first foam sheet, a hot-melt adhesive shaping cloth, and a second foam sheet in sequence from the inner surface to the outer surface, the first foam sheet, the hot-melt adhesive shaping cloth, and the second foam sheet are hot-pressed, and at least one non-slip and breathable area is convexly provided on the inner surface of the main body, the non-slip and breathable area includes a first raised portion and a second raised portion, the first raised portion is not connected to the second raised portion, the first raised portion and the second raised portion are both located at the waist of the shoe, and are surrounded to form a mesh structure.

[0006] By providing a heel groove, it is convenient to accommodate the heel and reduce the possibility of heel falling off. The first raised portion and the second raised portion can increase friction and reduce the possibility of heel falling off. The first raised portion and the second raised portion extend from the side close to the heel groove to the waist of the shoe, so that they are both provided close to the heel and the back of the shoe, so that they can better fit the waist of the human foot and have good wrapping. The mesh structure surrounded by the first raised portion and the second raised portion can prevent the waist of the shoe from being completely close to the foot, and has a certain avoidance space, which is convenient for air circulation inside the shoe, thereby achieving better ventilation and reducing the feeling of stuffiness.

[0007] The first protrusion is not connected to the second protrusion, and the mesh structure formed has better air circulation, so the obtained shoe has better air permeability. The first foam sheet and the second foam sheet used in the present application both have better air permeability, making the rear shoe body more breathable. The hot melt adhesive shaping cloth heat-presses the first foam sheet and the second foam sheet to stably form a rear shoe body with a stable structure.

[0008] In summary, the first foam sheet and the second foam sheet have better air permeability, and the first protrusion and the second protrusion form a mesh structure with better air flow and anti-slip effect, thereby improving the anti-slip and air permeability of the rear shoe body, so that the resulting shoes are not easy to produce stuffiness and are not prone to heel falling off.

[0009] Preferably, a third protrusion is convexly provided on the inner surface of the main body, the third protrusion is located between the heel groove of the main body and the anti-slip breathable area, and the third protrusion is not connected to the first protrusion and the second protrusion.

[0010] By setting the third protrusion, in combination with the first protrusion and the second protrusion, the mesh joint surface formed has better anti-slip properties and air circulation, so that the rear shoe body has better air permeability and anti-slip properties, reducing the possibility of heel falling off when wearing the shoes, and making the air circulation in the shoes smooth when wearing the shoes, reducing the possibility of stuffiness.

[0011] Preferably, the height of the first protrusion is 0.5-2.1 mm. By using the above height range of the first protrusion, the anti-slip effect can be ensured while avoiding the protrusion being too high to cause discomfort when wearing.

[0012] Preferably, the first protrusion has the same height as the second protrusion and the third protrusion.

[0013] By arranging the first protrusion, the second protrusion and the third protrusion with the same height, it can be ensured that the three have consistent stability when providing the anti-slip effect.

[0014] Preferably, the thickness of the first foam sheet is greater than the thickness of the second foam sheet.

[0015] By setting foam sheets of different thicknesses, the breathability and comfort of the shoe body can be adjusted while ensuring the stability of the overall structure.

[0016] Preferably, the first foam sheet comprises a spandex layer and a first foam layer, the spandex layer is connected to the first foam layer via a first waterproof and breathable adhesive layer, and the first foam layer is connected to the hot melt adhesive shaping cloth.

[0017] The first waterproof and breathable adhesive layer can stably connect the spandex layer and the first foam layer, thereby improving the layer structure stability of the rear shoe body, wherein the spandex layer has better softness. When wearing the shoe, the spandex layer contacts the human foot, thereby improving the comfort of wearing the shoe. The first foam layer has a breathable effect, thereby improving the breathability of the shoe. At the same time, the first waterproof and breathable adhesive layer also has waterproof performance, thereby reducing water seepage inside the shoe.

[0018] Preferably, the thickness of the first foam layer is 5-15 mm.

[0019] The above thickness range of the first foam layer can ensure that the shoe body maintains structural stability and breathability while providing sufficient comfort.

[0020] Preferably, the second foam sheet includes a second foam layer and a mesh layer, the second foam layer and the mesh layer are connected via the second waterproof and breathable adhesive layer, and the second foam layer is connected to the hot-melt adhesive shaping cloth.

[0021] The provision of the mesh layer further enhances the air permeability of the second foam sheet, while the second waterproof and breathable adhesive layer ensures the stability and waterproof performance of the structure.

[0022] Preferably, the thickness of the second foam layer is 2-6 mm.

[0023] Through the thickness range of the above two foam layers, the overall strength and durability of the shoe body can be taken into account while ensuring breathability.

[0024] Preferably, the first waterproof breathable adhesive layer and the second waterproof breathable adhesive layer are both PUR hot melt adhesive layers. The PUR hot melt adhesive layer has the advantages of good bonding strength, good water resistance and air permeability of the PUR hot melt adhesive film, which can ensure a firm bond between the layers, so that the rear shoe body has better air permeability and anti-slip properties.

[0025] Preferably, the first foam layer and the second foam layer are each provided with at least one ventilation hole. The provision of the ventilation hole can further improve the air permeability of the first foam layer and the second foam layer, thereby enhancing the overall air permeability of the rear shoe body and also improving the wear resistance of the rear shoe body.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The first foam sheet and the second foam sheet have better air permeability, and the first protrusion and the second protrusion form a mesh structure with better air flow and anti-skid effect, thereby improving the anti-skid and air permeability of the rear shoe body, so that the obtained shoes are not easy to produce stuffiness and are not easy to fall off the heel.

[0028] 2. By setting the third protrusion, in combination with the first protrusion and the second protrusion, the mesh joint surface formed has better anti-slip properties and air circulation, so that the rear shoe body has better air permeability and anti-slip properties, reducing the possibility of heel falling when wearing the shoes, and making the air circulation in the shoes smooth when wearing the shoes, reducing the possibility of stuffiness.

[0029] 3. The provision of the ventilation holes can further improve the air permeability of the first foam layer and the second foam layer, thereby enhancing the overall air permeability of the rear shoe body and also improving the wear resistance of the rear shoe body.

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] Example 1

[0037] The present application embodiment discloses a non-slip breathable rear shoe body. Figure 1 and Figure 2, including a body 1, the inner surface of the body 1 is provided with a heel groove 11, the body 1 is provided with a first foam sheet 2, a hot melt adhesive shaping cloth 3, and a second foam sheet 4 in sequence from the inner surface to the outer surface, the first foam sheet 2, the hot melt adhesive shaping cloth 3, and the second foam sheet 4 are hot-pressed to form a rear shoe body with a stable structure; the second foam sheet 4 includes a second foam layer 41, a second waterproof and breathable adhesive layer 43, and a mesh layer 42, the second foam layer 41 and the mesh layer 42 are connected by the second waterproof and breathable adhesive layer 43, so that the second foam layer 41 and the mesh layer 42 are closely connected, and the second foam layer 41 is hot-melt connected with the hot melt adhesive shaping cloth 3. Among them, the thickness of the second foam layer 41 can be 2mm, 3mm, 4mm, 5mm or 6mm, and the preferred thickness in this embodiment is 4mm. This thickness selection makes the rear shoe body have better air permeability and comfort.

[0038] The first foam sheet 2 includes a first foam layer 22 and a spandex layer 21 connected by hot-melt adhesive shaping cloth 3, and the spandex layer 21 is connected by hot-melt with the first foam layer 22 through a first waterproof and breathable adhesive layer 23. When wearing shoes, the spandex layer 21 contacts the foot, which improves the comfort of wearing shoes. The thickness of the first foam layer 22 is greater than the thickness of the second foam layer 41, and the thickness of the first foam layer 22 can be 5mm, 8mm, 10mm, 12mm, 13mm, 14mm or 15mm, and the present application selects 15mm. The connection and thickness setting of the above structure form a stable heel groove, so that the shoes produced by the rear shoe body have better air permeability and anti-slip properties, and the structure of the rear shoe body has better stability.

[0039] Furthermore, the first waterproof breathable adhesive layer 23 and the second waterproof breathable adhesive layer 43 are both PUR hot melt adhesive layers, which not only improve the connection stability between the layer structures but also play a waterproof role.

[0040] The inner surface of the body 1 is provided with at least one anti-slip breathable area. The shoe waist of the present application refers to the inner waist and the outer waist of the shoe. The heel groove 11 of the body 1 is located between the inner waist and the outer waist. Figure 1 As shown, in this embodiment, the outer waist and the inner waist of the inner surface of the rear shoe body are both provided with anti-skid and breathable areas, and the anti-skid and breathable areas include a first raised portion 5 and a second raised portion 6, the first raised portion 5 is not connected to the second raised portion 6, the first raised portion 5 is close to the lower edge of the body 1, the second raised portion 6 is close to the upper edge of the body 1, the first raised portion 5 is not connected to the second raised portion 6, the first raised portion 5 and the second raised portion 6 are both located at the shoe waist and are surrounded to form a mesh structure. This arrangement enables the rear shoe body to have both better air permeability and anti-skid properties.

[0041] The implementation principle of the anti-slip and breathable rear shoe body in the embodiment of the present application is: by placing the first foam sheet 2, the hot melt adhesive shaping cloth 3, and the second foam sheet 4 in sequence and hot pressing them, the first protrusion 5 and the second protrusion 6 are formed on the inner side of the main body 1, and the first protrusion 5 and the second protrusion 6 are surrounded to form a mesh structure, so that the rear shoe body has better anti-slip properties. When used in shoes, it has better ventilation and anti-heel falling effects.

[0042] Example 2

[0043] The difference between Example 2 and Example 1 is that: Figure 3 A third protrusion 7 is convexly provided on the inner surface of the main body 1, and the third protrusion 7 is located at the edge of the heel groove 11 on the inner surface of the main body 1. The third protrusion 7 is not connected to the first protrusion 5 and the second protrusion 6, which further improves the anti-slip property of the rear shoe body. When the shoes are worn, the internal air circulation is good, which has better breathability and avoids the feeling of stuffiness (the rest is the same as Example 1).

[0044] Example 3

[0045] The difference between Example 3 and Example 2 is that: Figure 4 As shown, the first foam layer 22 and the second foam layer 41 are each provided with at least one breathable through hole 8. Taking the first foam layer 22 as an example, the number of the breathable through holes 8 provided in the first foam layer 22 may be 1, 2, 5, 10, 20, 30, 50, 100, etc. The number of the breathable through holes 8 may be irregularly distributed or arranged in a matrix, and the breathable through holes 8 of the first foam layer 22 are connected to the breathable through holes 8 of the second foam layer 41, or not connected. The breathable through holes 8 in this embodiment are irregularly distributed, and the breathable through holes 8 of the first foam layer 22 are not connected to the breathable through holes 8 of the second foam layer 41.

[0046] The implementation principle of the anti-slip and breathable rear shoe body of this embodiment is as follows: ventilation holes 8 are opened on the first foam layer 22 and the second foam layer 41, and then the first foam sheet 2 and the second foam sheet 4 are formed through the action of the PUR hot melt adhesive layer (the rest is the same as in Embodiment 1).

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
