Description

Technical Field

[0001] The utility model belongs to the technical field of shoe soles, and in particular relates to a multi-purpose amphibious sports shoe outsole. Background Art

[0002] In outdoor sports, many outdoor sports shoes only have a single waterproof function or a drainage function. Traditional drainage shoes will allow road water to seep in through the drainage holes on rainy days or on flooded roads, causing the inside of the shoes to get wet or even accumulate water. Waterproof shoes cannot drain water in wading environments, causing water to accumulate in the shoes. In order to make the shoes suitable for both environments, a new outsole is designed and invented so that the shoes will not get water when worn in non-wading environments or on rainy days, ensuring that the feet are dry and comfortable. A sole that can quickly drain water in a wading environment is particularly important.

[0003] The prior art (CN 206371584 U) discloses an amphibious mosquito repellent outdoor shoe, specifically disclosing that a plurality of through holes are evenly distributed on the sole, the through holes are arranged through the bottom surface and the top surface of the sole, the insole and the shoe body are separate structures, a plurality of protrusions are arranged on the bottom surface of the insole, the number and positions of the protrusions correspond to the through holes, and the shape of the protrusions is cone-shaped. When the insole is taken out of the shoe body, the through holes of the sole are in a conducting state, and the moisture in the shoe will be discharged from the through holes in time after passing through deeper water. When the insole is placed in the shoe body, the protrusions are plugged into the through holes to close the through holes.

[0004] Although the above-mentioned prior art can be used for both water and water, there are many sharp stones, branches, shrubs, etc. outdoors. Opening holes at the bottom of the sole for drainage may cause the risk of sharp objects penetrating through the holes and injuring the feet.

[0005] To this end, the technical problem to be solved by the utility model is that the existing amphibious outdoor shoes have holes at the bottom of the soles for drainage. Since there are many sharp stones, branches, shrubs, etc. outdoors, there may be a hidden danger of sharp objects penetrating through the holes and injuring the feet by opening holes at the bottom of the soles for drainage.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 8 and Fig. 9 As shown, the utility model provides a multi-purpose amphibious sports shoe outsole, comprising a sole body composed of a sole portion, an arch portion and a heel portion, the sole body comprising a rubber layer 1, a polyurethane layer 2, an anti-puncture layer 3 and a replaceable midsole 4; the bottom of the rubber layer 1 is provided with an anti-slip pattern 11, the outer edge of the polyurethane layer 2 extends upward, and drainage holes 21 are symmetrically provided on both sides of the outer edge of the polyurethane layer 2;

[0031] The replaceable midsole 4 includes a water-blocking midsole 41 and a drainage midsole 42. The water-blocking midsole 41 is symmetrically provided with sealing plugs 411 on both sides of the outer edge of the forefoot. The drainage midsole 42 is provided with drainage grooves on the upper surface. The drainage grooves include a longitudinal drainage groove 421, a transverse drainage groove 422 and an oblique drainage groove 423. The transverse drainage groove 422 and the oblique drainage groove 423 are interconnected with the longitudinal drainage groove 421.

[0032] The number of sealing plugs 411, the number of transverse drainage grooves 422 and the number of drainage holes 21 are all consistent;

[0033] When in a wading environment, the anti-puncture layer 3 is provided with a water-blocking bottom 41, and the sealing plug 411 is blocked in the drainage hole 21, and the sealing plug 411 is interference-fitted with the hole wall of the drainage hole 21;

[0034] When in a non-water-wading environment, the anti-puncture layer 3 is provided with a drainage midsole 42 , and the transverse drainage groove 422 is connected to the drainage hole 21 .

[0035] The utility model is provided with an anti-skid pattern on the rubber layer, which can adapt to the anti-skid requirements of different environments; a drainage hole is provided on the polyurethane layer, the drainage hole is communicated with the drainage groove, the drainage hole can quickly discharge the water in the drainage groove; an anti-puncture layer is provided, which can effectively protect the footwear and prevent sharp objects on the ground from penetrating the bottom of the footwear and injuring the foot; a replaceable drainage midsole and a water-blocking midsole are provided, which have excellent drainage function in a wading environment, and in a non-wading environment, water will not enter the inside of the footwear and ensure that the foot is dry.

[0036] As shown in Figure 1, the outsole has four layers and adopts a molding process. The rubber layer 1 is vulcanized and formed using a flat vulcanizer, and the polyurethane layer 2 is injected by an injection method to form a dual-density sole, which achieves the unity of functionality and comfort. It has the advantages of light weight, excellent elasticity and good cushioning performance. The anti-puncture layer 3 is located above the polyurethane layer 2, and the replaceable midsole 4 is placed in the shoe to obtain the final product.

[0037] like Figure 2 , Figure 3 and Figure 4 As shown, the arch of the rubber layer 1 is concave upward, and the edges of the arch, heel and toes extend upward. The rubber layer 1 is provided with anti-slip patterns 11 at the sole and heel to increase the ground contact area of ​​the pattern and increase stability to meet the anti-slip requirements when used in different environments. The rubber layer 1 is strong, durable, stable and anti-slip.

[0038] The raw materials of the rubber layer 1 are synthetic rubber, natural rubber, accelerator, sulfur, reinforcing agent and the like.

[0039] like Figure 5 As shown, the polyurethane layer 2 is symmetrically provided with three pairs of drainage holes 21 on both sides of the outer edge of the forefoot, through which water can be quickly discharged in a wading environment. The drainage holes are arranged on the side of the shoe to avoid anti-puncture materials that are not water-permeable.

[0040] The polyurethane layer 2 is the part that plays a bonding role between the sole and the upper. The raw materials of the polyurethane layer 2 are divided into polyether polyol (material A), polyisocyanate (material B), water, diamine chain extender, catalyst, foaming agent, and uniform foaming agent; the raw material of the polyurethane layer 2 is liquid, and can penetrate into the leather and cloth surfaces of the upper at the moment of injection into the mold during production. Therefore, the bonding strength between the polyurethane sole and the upper is extremely high. The polyurethane material has high strength, good elasticity, low density, and light weight, which meets the needs of shoes and boots.

[0041] like Figure 6 As shown, the material of the anti-puncture layer 3 is ultra-high molecular weight polyethylene filaments. The anti-puncture layer 3 is located between the polyurethane layer 2 and the replaceable midsole 4, which can effectively protect the shoes and boots and prevent sharp objects on the ground from penetrating the bottom of the shoes and boots to injure the feet.

[0042] like Figure 7 As shown, the outer edge of the replaceable midsole 4 contacts the drainage hole 21 on the outside of the polyurethane layer 2, and the raw materials of the replaceable midsole 4 are EVA, OBC, SEBS, a cross-linking agent, a filler, a reinforcing and toughening agent, and a wear-resistant agent.

[0043] like Fig.10 As shown, the sole of the replaceable midsole 4 is concave to fit the curvature of the sole of the human foot, and the overall structure is thick in the middle in the transverse direction and thin on both sides. The head end of the replaceable midsole 4 is the thinnest, and the longitudinal direction gradually thickens as it extends downward from the head end, and the sole and heel parts have the same thickness.

[0044] like Figure 8 As shown, the water-blocking midsole 41 is symmetrically provided with three pairs of sealing plugs 411 on both sides of the outer edge of the forefoot. The sealing plugs 411 are interference fit with the drainage holes 21 provided on both sides of the outer edge of the forefoot of the polyurethane layer 2, thereby preventing water from entering the inside of the shoe.

[0045] like Fig. 9 As shown, the upper surface of the drainage midsole 42 is provided with drainage grooves, and a longitudinal drainage groove 421 is provided along the central axis of the drainage midsole 42, and the longitudinal drainage groove 421 runs through the entire drainage midsole 42; six transverse drainage grooves 422 are arranged at intervals at the forefoot position of the drainage midsole 42, symmetrically distributed on both sides of the longitudinal drainage groove 421, and the six transverse drainage grooves 422 have the same width and extend to the outer edge of the drainage midsole 42; four oblique drainage grooves 423 are arranged at intervals at the heel of the drainage midsole 42, forming two groups of herringbone shapes.

[0046] The transverse drainage grooves 422 and the oblique drainage grooves 423 are interconnected with the longitudinal drainage grooves 421, which helps to drain the internal circulating water. The provision of drainage grooves strengthens the circulation of water in the shoe, diverts the water flow, and finally discharges it out of the shoe through the drainage holes 21, thereby improving the breathability and quick-drying performance.

[0047] The two replaceable midsoles perform functions alternately. The water-blocking midsole 41 seals the drainage hole 21 to prevent the accumulated water outside the shoe from entering the shoe, thereby achieving the water-blocking function; the drainage midsole 42 drains the accumulated water in the shoe by means of drainage grooves arranged on the upper surface to flow out of the drainage hole 21 along the grooves.

[0048] In actual use, different midsoles can be selected according to different environments. In a non-water-wading environment, the water-blocking midsole 41 is used and placed in the shoe. The sealing plugs 411 arranged on both sides of the forefoot edge of the water-blocking midsole 41 are interference-fitted with the drainage holes 21, thereby preventing external water from entering the shoe and ensuring that the feet are dry. In a water-wading environment, the drainage midsole 42 is used and placed in the shoe. The drainage grooves arranged on the upper surface of the drainage midsole 42 cooperate with the drainage holes 21, thereby quickly draining the water in the shoe and improving the breathability and quick-drying performance of the footwear.

[0049] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
