Description

Technical Field

[0001] This utility model relates to the field of breathable shoe technology, and in particular to an improved self-breathing shock-absorbing elastic shoe sole. Background Technology

[0002] Shoes, as an essential part of daily life, come in various functions and styles. However, regardless of their appearance, comfort and adequate protection for the feet are paramount. With the rapid development of living standards, people's demands for shoes are increasing. Some shoes require breathability and dryness, others warmth, and still others slip resistance. Shock absorption is particularly important. When walking or exercising, especially during strenuous activity, the impact transmitted from the ground to the feet can cause significant damage, especially to the ankles and knees. Shoes need shock absorption to reduce the impact on the feet and body. The shock absorption of shoes directly affects comfort and athletic performance, especially in competitive sports. A pair of comfortable shoes with good shock absorption not only protects an athlete's feet but also improves performance. From a comfort perspective, a well-cushioned sole absorbs more impact from the ground during exercise.

[0003] Patent authorization number CN221653716U discloses an ultralight shock-absorbing and breathable sole and shoe, including an outsole and a midsole stacked on the outsole. The midsole is made of elastic material, and the bottom surface of the midsole has multiple grooves. The inner wall of the grooves and the top surface of the outsole form a closed cavity. The bottom of the grooves has vents that connect to the top of the midsole. By providing a cylindrical cavity in the midsole, and vents that communicate with the shoe cavity on the top of the cavity, when the foot is stepped on, the midsole compresses and deforms to expel the gas in the cavity, promoting airflow between the sole and the midsole, keeping the sole dry, preventing bacterial growth, and protecting foot health.

[0004] However, based on the full text and accompanying drawings of the aforementioned patent, although the midsole is made of elastic material, it is relatively difficult for the midsole to deform under normal walking pressure in practice. This means the compression of the grooves is relatively limited, thus affecting the final air-wicking effect. In other words, the existing technology still has certain shortcomings. Therefore, this application discloses an improved self-aspirating shock-absorbing elastic sole to overcome these shortcomings. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and provides an improved self-breathing shock-absorbing elastic sole that enables air exchange inside the shoe to help keep feet dry; it has good elasticity and is comfortable to walk on.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] An improved self-aspirating, shock-absorbing elastic sole includes a bottom layer and an insole. The bottom layer has upward-protruding edges forming flanges, which surround and form mounting positions. The insole is embedded into the mounting positions, and the edges of the insole are tightly joined with the base of the flanges to form a closed space between the bottom layer and the insole. A first longitudinally compressible elastic post is provided on the lower surface of the insole corresponding to the forefoot area, and a second longitudinally compressible elastic post is provided on the lower surface of the insole corresponding to the heel area. The outer diameter of the second elastic post is larger than that of the first elastic post. The mounting positions of the bottom layer correspond to the forefoot area... The inner pad has a receiving surface, and the bottom mounting position has a grid frame corresponding to the heel area. When the inner pad is embedded and assembled into the mounting position, the lower end of the first elastic column is in contact with the receiving surface, and the lower end of the second elastic column is inserted into the mesh of the grid frame. The inner pad has several ventilation holes. When a person steps on it, the first and second elastic columns are deformed and compressed, which increases the air pressure in the closed space and squeezes the gas out of the ventilation holes. When the person lifts their foot, the first and second elastic columns are decompressed and reset, which decreases the air pressure in the closed space and draws in external gas through the ventilation holes, thereby achieving ventilation.

[0008] Furthermore, the inner pad is designed in an arc shape that matches the shape of the forefoot, and the inner pad is designed in an arched flat shape for the heel.

[0009] Furthermore, the grid frame includes staggered support walls, with support columns at the intersections of the support walls, and the support walls and support columns are staggered from the second elastic column; the upper surfaces of the support walls and support columns are flush; the height of the second elastic column is higher than the height of the support walls and support columns.

[0010] Furthermore, the diameter of the support column is 6 to 10 mm; the thickness of the support wall is 2.5 to 3.5 mm.

[0011] Furthermore, the first elastic column and the second elastic column have the same structure, both including a first cylinder and a second cylinder connected by a hollow structure; the diameter of the first cylinder is larger than the diameter of the second cylinder, and the second cylinder is located below the first cylinder; the junction of the first cylinder and the second cylinder forms a smooth, downward retracting transition section.

[0012] Furthermore, the diameter of the first cylinder is 13 to 14 mm, and the diameter of the second cylinder is 9 to 10 mm; the wall thickness of the first cylinder and the second cylinder is 2 to 3 mm.

[0013] Furthermore, the ventilation holes are located in the front area of ​​the inner pad, corresponding to the toes.

[0014] Furthermore, the bottom surface of the bottom layer is provided with a plurality of first anti-slip blocks in the middle of the forefoot area, and a first hydrophobic inner groove is provided between adjacent first anti-slip blocks. A first hydrophobic outer groove communicating with the first hydrophobic inner groove is provided around the bottom surface of the bottom layer. The bottom surface of the bottom layer is provided with a plurality of second anti-slip blocks in the middle of the heel area, and a second hydrophobic inner groove is provided between adjacent second anti-slip blocks. A second hydrophobic outer groove communicating with the second hydrophobic inner groove is provided around the bottom surface of the bottom layer.

[0015] Furthermore, the opening width of the first and second hydrophobic outer grooves gradually narrows from the inside out.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When a person walks, the first and second elastic columns are compressed and reset, allowing the closed space to exchange air with the outside world. This airflow circulates in the sole of the shoe, keeping the inside dry. In addition, the first and second elastic columns themselves have excellent elasticity, making walking comfortable.

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] like Figures 1 to 6 As shown, this utility model claims protection for an improved self-aspirating shock-absorbing elastic sole, including a bottom layer 1 and an inner pad 2. The four edges of the bottom layer 1 protrude upward to form a flange 101, and the flange 101 surrounds and forms an mounting position. The inner pad 2 is embedded and assembled into the mounting position, and the four edges of the inner pad 2 are tightly connected with the root of the flange 101 so that the bottom layer 1 and the inner pad 2 enclose a closed space. When the inner pad 2 is combined with the bottom layer 1, the flange 101 is still higher than the surface of the inner pad 2 so that the inner side of the flange 101 protrudes and is fixed to the shoe upper.

[0028] The lower surface of the inner pad 2 is provided with a first elastic column 3 that can be compressed longitudinally corresponding to the forefoot area, and the lower surface of the inner pad 2 is provided with a second elastic column 4 that can be compressed longitudinally corresponding to the heel area. The first elastic column 3 and the second elastic column 4 are made of silicone material, so they have good elasticity. The outer diameter D1 of the second elastic column 4 is larger than the outer diameter D2 of the first elastic column 3, which means that the load-bearing capacity of the second elastic column 4 is greater than that of the first elastic column 3. Since the weight of the human body is concentrated in the heel area when stepping, it is necessary to increase the load-bearing effect of the second elastic column 4.

[0029] The mounting position of the bottom layer 1 has a receiving surface 102 corresponding to the forefoot area, and a grid frame 103 corresponding to the heel area. When the inner pad 2 is embedded and assembled into the mounting position, the lower end of the first elastic column 3 is connected to the receiving surface 102, and the lower end of the second elastic column 4 is inserted into the mesh 104 of the grid frame 103. The mesh 104 is recessed, so the insertion of the lower end of the elastic column 4 into the grid frame 103 not only makes the lower end of the inner pad 2 fit tightly with the bottom layer 1, but also achieves a certain positioning effect, that is, makes it difficult for the inner pad 2 to move in the bottom layer 1. In addition, it also increases the air capacity of the closed space formed by the bottom layer 1 and the inner pad 2.

[0030] The grid frame 103 includes staggered support walls 1031, with support columns 1032 at the intersections of the support walls 1031. The support walls 1031 and support columns 1032 are staggered with the second elastic column 4. The support walls 1031 and support columns 1032 work together to bear the load. Furthermore, the height of the second elastic column 4 is higher than the height of the support walls 1031 and support columns 1032. That is, when the second elastic column 4 is inserted into the mesh 104, its upper end slightly protrudes from the upper surfaces of the support walls 1031 and support columns 1032, thus allowing the second elastic column 4 to have compression space. In other words, the grid frame 103 has a certain limiting effect on the compression of the second elastic column 4. When stepped on, the second elastic column 4 is compressed. When the compression reaches the point where the bottom of the inner pad 2 connected to the second elastic column 4 comes into contact with the upper surface of the support wall 1031 and the support column 1032, the second elastic column 4 will stop compressing (in reality, the support column 1032 is also made of rubber material, so it will also undergo a slight deformation). Therefore, the grid frame 103 also has a certain protective effect on the second elastic column 4, preventing the second elastic column 4 from being over-compressed and shortening its service life or affecting its reset.

[0031] The upper surfaces of the support wall 1031 and the support column 1032 are flush, which helps to support the bottom part of the inner pad 2 at the connection with the second elastic column 4 during compression.

[0032] Both the first elastic column 3 and the second elastic column 4 have the same structure, including a first cylinder 401 and a second cylinder 402 connected by a hollow structure. The diameter of the first cylinder 401 is larger than the diameter of the second cylinder 402, and the second cylinder 402 is located below the first cylinder 401. The joint between the first cylinder 401 and the second cylinder 402 forms a smooth, downward-retracting transition section. The hollow structure of the first cylinder 401 provides space for the second cylinder 402 to retract upward. When stepped on, the second cylinder 402 retracts to the first cylinder 401, causing the whole to be compressed longitudinally. The hollow structure of the first cylinder 401 and the second cylinder 402 also helps to reduce the weight of the inner pad 2, making the whole lighter.

[0033] The inner pad 2 is provided with several ventilation holes 201, which are located in the front area of ​​the inner pad 2 corresponding to the toes. The inventors found that the toes area has more foot sweat, so setting the ventilation holes 201 in this area helps to ventilate and remove heat and foot sweat. When a person steps on the pad, the first elastic column 3 and the second elastic column 4 are deformed and compressed, which increases the air pressure in the closed space and squeezes the gas out of the ventilation holes 201. When the person lifts their foot, the first elastic column 3 and the second elastic column 4 are decompressed and reset, which decreases the air pressure in the closed space and draws in external gas through the ventilation holes 201, thereby achieving ventilation.

[0034] from Figure 3 As can be seen, the inner pad 2 is designed with an arc shape that matches the shape of the forefoot, so that it fits the forefoot when worn, thereby improving comfort; the inner pad 2 is designed with an arched flat shape for the heel area. Since the heel area bears a lot of weight and requires a high degree of stability, the arched flat design helps to achieve a stable load-bearing effect.

[0035] The diameter of the support column 1032 is 6 to 10 mm; the thickness of the support wall 1031 is 2.5 to 3.5 mm; in this embodiment, the diameter D4 of the support column 1032 is 8 mm; the thickness D3 of the support wall 1031 is 3 mm. The inventors have found that the support column 1032 and the support wall 1031 of this size can meet the load-bearing capacity of ordinary people, and can also undergo slight deformation when stepped on, without being too stiff and causing discomfort.

[0036] The diameter of the first cylinder 401 is 13 to 14 mm, and the diameter of the second cylinder 402 is 9 to 10 mm; the wall thickness of the first cylinder 401 and the second cylinder 402 is 2 to 3 mm; in this embodiment, the diameter of the first cylinder 401 is 13.1 mm, the diameter of the second cylinder 402 is 9.3 mm, and the wall thickness of the first cylinder 401 and the second cylinder 402 is 2.5 mm; therefore, the inventors have found that the first cylinder 401 and the second cylinder 402 of this specification can not only meet the requirements of high elasticity compression, but also have a moderate load-bearing capacity, so that there will be no effect of stepping into the void or collapsing when stepping on them, and the center of gravity is stable.

[0037] In addition, the distance between adjacent first elastic columns 3 and adjacent second elastic columns 4 is controlled at 5 to 7 mm. This distribution is moderate and can meet the basic elasticity requirements without being too dense.

[0038] The bottom layer 1 has several first anti-slip blocks 5 in the middle of the forefoot area, and a first drainage inner groove 6 between adjacent first anti-slip blocks 5. The bottom surface of the bottom layer 1 has a first drainage outer groove 7 that communicates with the first drainage inner groove 6. The bottom layer 1 has several second anti-slip blocks 8 in the middle of the heel area, and a second drainage inner groove 9 between adjacent second anti-slip blocks 8. The bottom surface of the bottom layer 1 has a second drainage outer groove 10 that communicates with the second drainage inner groove 9.

[0039] The bottom surfaces of the first anti-slip block 5 and the second anti-slip block 8 can also be reinforced with friction patterns to enhance friction with the ground. The first hydrophobic inner groove 6, the first hydrophobic outer groove 7, the second hydrophobic inner groove 9, and the second hydrophobic outer groove 10 are all designed for hydrophobic purposes, similar to the tread pattern on tires. When walking on water in rainy weather or at other times, water below the bottom layer 1 will be drained outwards through the interaction of the first hydrophobic inner groove 6 and the first hydrophobic outer groove 7, and the second hydrophobic inner groove 9 and the second hydrophobic outer groove 10, preventing water from accumulating on the lower surface of the bottom layer 1 and causing slippage. Additionally, from... Figure 5 It can be seen that the opening width of the first hydrophobic outer groove 7 and the second hydrophobic outer groove 10 gradually narrows from the inside to the outside. Since the outer ends of the first hydrophobic outer groove 7 and the second hydrophobic outer groove 10 correspond to the edge of the bottom layer 1, the moderate narrowing can prevent the exposed opening from being too large and affecting the overall aesthetics.

[0040] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
