Description

Technical Field

[0001] The utility model relates to a lightweight breathable sole, in particular to a lightweight breathable sole, and belongs to the technical field of soles. Background Art

[0002] The sole is the bottom of the shoe, typically made of a wear-resistant, non-slip, and supportive material. Its primary function is to protect the wearer's foot, provide a comfortable walking experience, and ensure stability and safety when walking on various surfaces. The design and material choice of the sole vary depending on the type of shoe, its intended use, and the wearer's needs.

[0003] In order to improve the wear resistance and puncture resistance of existing soles, multiple layers of high-density materials are generally added to the soles. As a result, the soles are too heavy, which increases the load on the wearer's feet and affects the wearer's experience. In addition, the soles are relatively thick and have poor breathability.

[0004] Therefore, there is an urgent need to improve lightweight breathable soles to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a lightweight breathable sole, which is light in weight, comfortable to wear and has a good breathability effect.

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include: a lightweight breathable sole, including a comfort layer, a shock-absorbing layer and a wear-resistant layer arranged in sequence from top to bottom, a cavity is provided in the comfort layer, a plurality of support blocks are arranged in the cavity, and a plurality of support blocks are provided with air holes, a breathable layer is provided in the cavity, the upper end surface of the outer ring of the comfort layer is provided with a plurality of exhaust holes communicating with the cavity, and the lower end surface of the wear-resistant layer is provided with a plurality of buffering and anti-sliding blocks.

[0007] Preferably, the comfort layer is an EVA foam layer.

[0008] Preferably, the shock-absorbing layer is a thermoplastic polyurethane layer.

[0009] Preferably, the wear-resistant layer is a tendon layer.

[0010] Preferably, the breathable layer is a PVC woven layer, and an extrusion cavity is formed by a plurality of the support blocks. The lower end surface of the breathable layer is provided with a plurality of breathable cottons adapted to the extrusion cavity.

[0011] Preferably, the support block is a thermoplastic polyurethane block.

[0012] Preferably, there is a height difference between the upper end surface of the support block and the comfort layer, and the upper end surface of the breathable layer is flush with the upper end surface of the comfort layer.

[0013] Preferably, the buffer anti-sliding block includes a rubber base and a rubber anti-sliding block arranged inside the rubber base and slidably connected to the rubber base, and the rubber anti-sliding block is connected to the rubber base via a rubber block.

[0014] The utility model has at least the following beneficial effects:

[0015] 1. By utilizing a lightweight comfort layer, a shock-absorbing layer, and a wear-resistant layer, the shoe has good wearing comfort. When the user steps on the shoe, the breathable layer and the support block are stepped on and squeezed, thereby squeezing the cavity. Several air holes and exhaust holes are used to exhaust the gas outward, so that the gas enters the shoe for ventilation. When the foot is lifted, the outside air will also enter the squeezing cavity through the air holes and exhaust holes, and pass through the breathable layer, thereby bringing breathable comfort to the user's feet.

[0016] 2. When the wearer steps on the shoe, the rubber anti-sliding block slides slightly in the rubber base. The setting of the rubber block makes it have an elastic effect in itself and can also stretch and rebound, which greatly improves the buffering effect of the anti-sliding block when stepping on the shoe.

[0023] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] like Figure 1-Figure 4 As shown, the lightweight breathable sole provided by this embodiment includes a comfort layer 1, a shock-absorbing layer 2 and a wear-resistant layer 3 arranged in sequence from top to bottom. The comfort layer 1 is an EVA foam layer, which has good flexibility and elasticity and is very comfortable to wear, thereby improving the comfort of the user when stepping on it; the shock-absorbing layer 2 is a thermoplastic polyurethane layer, which has excellent wear resistance, tear resistance and elasticity, so that the shock-absorbing layer 2 has a shock-absorbing effect when stepping on it; the wear-resistant layer 3 is a tendon layer. The tendon sole has good elasticity and low-temperature resistance, is wear-resistant and non-slip, and has a relatively light texture, which ensures light weight without affecting the wear resistance of the sole and improves the service life;

[0025] A cavity 4 is defined within the comfort layer 1, within which a plurality of support blocks 5 are arranged, each of which has a ventilation hole 6. A breathable layer 7 is defined within the cavity 4, and the upper end surface of the outer ring of the comfort layer 1 is provided with a plurality of exhaust holes 8 communicating with the cavity 4.

[0026] Furthermore, the breathable layer 7 is a PVC woven layer, and an extrusion cavity 10 is formed by a plurality of support blocks 5. The lower end surface of the breathable layer 7 is provided with a plurality of breathable cottons 11 adapted to the extrusion cavity 10. The provision of the breathable cottons 11 not only retains the comfort when stepping on, but also does not affect the ventilation effect of the extrusion cavity 10 and the plurality of air holes 6 and the exhaust holes 8.

[0027] When the user steps on the shoe, the breathable layer 7 and the support block 5 are stepped on and squeezed, thereby squeezing the extrusion cavity 10. The air is exhausted outwards through the plurality of air holes 6 and the exhaust holes 8, so that the air enters the shoe for ventilation. When the user lifts the foot, the outside air also enters the extrusion cavity 10 through the air holes 6 and the exhaust holes 8, and passes through the breathable layer 7, thereby providing breathable comfort to the user's foot.

[0028] Furthermore, the support block 5 is a thermoplastic polyurethane block, which combines hardness and softness, has excellent wear resistance, tear resistance and elasticity, and improves support and elasticity when stepping on. There is a height difference between the upper end surface of the support block 5 and the comfort layer 1, and the upper end surface of the breathable layer 7 is flush with the upper end surface of the comfort layer 1, ensuring good comfort when stepping on.

[0029] The lower end surface of the wear-resistant layer 3 is provided with several buffer anti-slip blocks 9. The buffer anti-slip blocks 9 include a rubber base 901 and a rubber anti-slip block 902 arranged inside the rubber base 901 and slidingly connected to the rubber base 901. The rubber anti-slip block 902 can greatly improve the anti-slip effect of the sole. The rubber anti-slip block 902 is connected to the rubber base 901 through a rubber block 903. When the wearer steps on it, the rubber anti-slip block 902 slides slightly in the rubber base 901. The setting of the rubber block 903 makes it have an elastic effect and can also be stretched and rebounded, which greatly improves the buffering effect of the buffer anti-slip block 9 when stepping on it. It should be noted that through the connection of the rubber block 903, the rubber anti-slip block 902 will only slide slightly elastically on the rubber base 901 and will not turn outward.

[0030] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0031] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0032] The above description shows and describes several preferred embodiments of the present invention. However, as previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge in the relevant field. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
