Description

A shoe sole capable of shock absorption and ventilation Technical Field

[0001] The invention relates to the technical field of soles, in particular to a sole capable of shock absorption and ventilation. Background Art

[0002] Shoes are a common daily necessity used to protect the feet from being pricked by sharp objects when walking on the road. Traditional shoes are of a covered structure, with the upper only having a notch at the ankle. The sweat seeping from the surface of the sole of the foot is absorbed by the socks and is difficult to evaporate to the outside of the upper, creating a humid environment inside the shoe, which is prone to breeding fungi and mold and causing athlete's foot, endangering the wearer's foot health. At present, most breathable shoes on the market have air holes added to the upper to improve the air permeability of the shoe, but this type of shoe still has shortcomings. The sole of the foot is in contact with the sole, and the sweat on the sole of the foot is difficult to evaporate from the air holes on the upper, which cannot meet the ventilation requirements. In addition, the sole is not equipped with a shock-absorbing device. When the user walks a lot while wearing the shoes, it is easy to get foot fatigue, which gives people a poor wearing experience. In addition, existing shoes lack a balance adjustment function, and long-term wear may affect walking posture or bone health.

[0003] Summary of the Invention

[0004] The present invention provides a shock-absorbing and ventilating sole, which at least solves the problem that existing shoes cannot meet the ventilation requirements of the soles of the feet and are not equipped with a shock-absorbing device, resulting in poor comfort.

[0005] The present invention adopts the following technical solutions:

[0006] A shoe sole capable of shock absorption and ventilation comprises an outsole, wherein the inner surface of the forefoot of the outsole is provided with a groove, and a plurality of ventilation holes connected to the groove are respectively provided on both sides of the outsole. A high-elasticity shock absorption and ventilation device is placed in the groove, and the high-elasticity shock absorption and ventilation device comprises a base plate and a plurality of inclined shock absorption and ventilation sheets arranged at equal intervals on the base plate. The inclined shock absorption and ventilation sheets are uniformly inclined forward or backward. When the shock absorption and ventilation device is filled into the groove, the inclined shock absorption and ventilation sheets protrude out of the groove by 0.7 to 2.0 mm.

[0007] According to a further improvement, the angle between the inclined shock-absorbing ventilation sheet and the bottom plate is 30° to 65°.

[0008] As a further improvement, the ventilation holes extend obliquely upward from the side walls of the outsole to the side walls of the groove, and the apertures of the ventilation holes gradually decrease from the outside to the inside.

[0009] As a further improvement, four ventilation holes communicating with the grooves are respectively provided on both sides of the outsole.

[0010] As a further improvement, the height of the high-elasticity shock-absorbing ventilation device is 3 to 6.5 mm.

[0011] In a further improvement, the outsole is integrally formed by injection molding of EVA.

[0012] As a further improvement, a porous gasket covering the groove and bonded to the top of the groove is provided on the outsole, and the porous gasket ensures that the forefoot is subjected to a stable force when the shoe is worn.

[0013] As a further improvement, a balance control hole tube is provided in the forefoot of the outsole to guide the walking posture.

[0014] As a further improvement, the total area of ​​the openings of the porous gasket is less than 1 / 2 of the total area of ​​the ventilation holes, or between 1 / 3 and 1 / 2 thereof, so as to achieve ventilation and exhaust mainly through the ventilation holes.

[0015] On the other hand, the present application provides a shoe adopting the sole described in the present application. The shoe comprises an upper and the sole described in the present application.

[0016] Further improved, the orifice tube assembly includes a closed end, an air intake section, a balancing pipe, a control chamber, a plug-in plug, an air horn, and a recovery base. The closed end is connected to the air intake section and the balancing pipe in sequence and then installed on one side of the control chamber. The plug-in plug is connected to the other side of the control chamber. The air horn and the balancing pipe are installed side by side on one side of the control chamber. The recovery base is installed at the lower part of the control chamber, and the balancing pipe is configured to be bent obliquely to the horizontal direction.

[0017] From the above description of the structure of the present invention, it can be seen that compared with the prior art, the present invention has the following advantages: a groove is provided on the inner surface of the forefoot of the outsole of the present invention, and ventilation holes connected to the outside are provided on both sides of the groove. The ventilation holes enhance the air permeability in the shoe, and a high-elasticity shock-absorbing ventilation device is adapted in the groove. The inclined shock-absorbing ventilation sheet is uniformly tilted forward or backward, and the inclined shock-absorbing ventilation sheet undergoes elastic deformation to enhance the shock-absorbing performance of the sole, and at the same time has an exhaust or air intake function, thereby improving the air convection exchange inside and outside the shoe, and promoting the sweat or sweat of the sole to be discharged from the sole through the ventilation holes, thereby ensuring that the sole is dry, hygienic and healthy, and the elastic shock-absorbing wearing experience is comfortable. The bottom of the porous gasket is provided with a waterproof and breathable cloth ， To achieve the effect of waterproof and breathable soles.

[0018] The porous gasket of the present application allows the forefoot to be more stably stressed when the shoe is worn, and the one-way discharge of gas inside the shoe also improves the gas environment inside the shoe, ensuring that the soles of the feet are dry, hygienic and healthy. The porous gasket can be better combined with the hole tube structure to achieve that when the walking posture is incorrect, the walking posture can be corrected with the sound of the air horn. When the walking posture is correct, no obvious correction prompt sound is issued, thereby cultivating good shoe wearing habits, further extending the service life of the shoes, and ensuring the health of human bones.

[0039] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0040] 1 to 7 , a shock-absorbing and ventilating sole is shown, comprising an outsole 1 , wherein a groove 11 is provided on the inner surface of the forefoot of the outsole 1 , and a plurality of ventilation holes 10 connected to the groove 11 are provided on both sides of the outsole 1 , wherein a high-elasticity shock-absorbing and ventilating device 2 is placed in the groove 11 , and the high-elasticity shock-absorbing and ventilating device 2 is composed of a base plate 22 and a plurality of inclined shock-absorbing and ventilating sheets 21 arranged at equal intervals on the base plate 22 , and the inclined shock-absorbing and ventilating sheets 21 are uniformly inclined forward or backward. When the shock-absorbing and ventilating device is filled in the groove 11 , the inclined shock-absorbing and ventilating sheets 21 extend out of the groove 11 by 0.7 to 2.0 mm. The inclined shock-absorbing and ventilating sheets 21 protrude from the sole of the shoe for easy stepping on by the sole of the foot, thereby achieving a shock-absorbing and ventilating effect.

[0041] 5 to 7 , the included angle between the inclined shock-absorbing ventilation sheet 21 and the bottom plate 22 (the included angle marked as B in FIG. 7 ) is 30° to 65°, preferably 61°.

[0042] 6 , the ventilation holes 10 extend obliquely upward from the side wall of the outsole 1 to the side wall of the groove 11 , and the aperture of the ventilation holes 10 gradually decreases from the outside to the inside. Preferably, the maximum aperture of the ventilation holes 10 is 6-18 mm, and the minimum aperture is 2-5 mm.

[0043] 1 , 2 and 5 , four ventilation holes 10 communicating with the grooves 11 are respectively provided on both sides of the outsole 1 .

[0044] The height of the high-elasticity shock-absorbing ventilation device 2 is 3 to 6.5 mm, and preferably 6.5 mm.

[0045] The outsole 1 is integrally formed by injection molding of EVA.

[0046] A groove 11 is provided on the inner surface of the forefoot of the outsole 1 of the present invention, and ventilation holes 10 connected to the outside are provided on both sides of the groove 11. The ventilation holes 10 enhance the air permeability inside the shoe. A high-elastic shock-absorbing ventilation device 2 is adapted in the groove 11. The inclined shock-absorbing ventilation sheet 21 is uniformly tilted forward or backward. The inclined shock-absorbing ventilation sheet 21 undergoes elastic deformation to improve the shock-absorbing performance of the sole. At the same time, it has an exhaust or intake function, improves the air convection exchange inside and outside the shoe, and promotes the sweat on the sole of the foot to be discharged from the ventilation hole 10 to the outside of the sole, ensuring that the sole of the foot is dry, hygienic and healthy, and the elastic shock-absorbing wearing experience is comfortable.

[0047] As shown in FIG8 , which is a schematic diagram of the installation of the porous gasket and the perforated tube, the outsole 1 is provided with a porous gasket 3 covering the groove 11 and bonded to the top of the groove 11. The porous gasket 3 ensures that the forefoot is subjected to a stable force when the shoe is worn. FIG8 is cut along the AA direction to obtain FIG12 and FIG15 ;

[0048] As shown in Figure 9, the preferred embodiment of the porous gasket 3 is that its bottom is concave, and an extension 31 is provided around the bottom of the porous gasket 3, as shown in the AA cross-sectional view in Figure 9 (back cross-sectional view, that is, the left side in Figure 9 is the surface appearance, and the right side is the cross-sectional bottom appearance), the opening of the porous gasket 3 is preferably a conical hole 32, and the back cross-sectional shape of the conical hole 32 is shown in the enlarged view C in the AA cross-sectional view in Figure 9. The material of the porous gasket is preferably a hard elastic rubber material, as shown in the enlarged view B in Figure 9, a circular groove 33 is provided on the upper surface of the porous gasket 3, and the conical small mouth of the conical hole 32 on the porous gasket 3 is provided in the circular groove 33, so that the porous gasket 3 can be further realized. When stepping on, the conical small mouth of the conical hole shrinks and closes, that is, the entire gasket 3 becomes airtight at this time, thereby facilitating downward exhaust and almost no upward exhaust. At the same time, the circular groove 33 is provided to collect sweat or gas, and the extension 31 is preferably made of a hard material. When not stepping on the foot, the tapered opening of the tapered hole 32 of the gasket 3 is in a normal open state, and the sole of the foot is in a breathable state. The specific shape of the tapered hole is not limited. For example, the upper surface can be a circle with a diameter of about 1 mm, and the bottom surface can be a circle with a diameter of about 3 mm.

[0049] At least the bottom of the porous gasket 3 is provided with a waterproof and breathable cloth, and preferably the waterproof and breathable cloth is integrally formed on the concave surface of the bottom of the porous gasket 3 to achieve a waterproof and breathable effect.

[0050] A balance control hole tube 4 is provided in the forefoot of the outsole to guide the walking posture. As shown in Figure 10, the hole tube 4 assembly includes a closed end 41, an air intake section 42, a balance pipe 43, a control compartment 44, a plug-in plug 45, an air horn 46, and a recovery base 47. The closed end 41 is connected to the air intake section 42 and the balance pipe 43 in sequence and then installed on one side of the control compartment 44. The plug-in plug 45 is connected to the other side of the control compartment 44. The air horn 46 and the balance pipe 43 are installed side by side on one side of the control compartment 44. The recovery base 47 is installed at the lower part of the control compartment 44. Preferably, holes are provided on at least part of the air intake section 42 to facilitate air intake. The balance pipe 43 is provided with an inclined horizontal bending structure, which is beneficial to the horizontal movement of the plug-in plug 45. In order to better achieve horizontal movement, as shown in Figure 12, an auxiliary rod 431 is preferably provided in the middle position of the balance pipe 43.

[0051] As shown in Figure 11, the plug-in plug 45 is a closed tube, and the plug-in plug 45 is composed of a restoring spring 451 and a convex sealing ring 452. A concave sealing groove 441 is provided at the connection between the control chamber 44 and the plug-in plug 45. When the convex sealing ring 452 cooperates with the concave sealing groove 441, the gas in the control chamber 44 can be sealed.

[0052] The following describes the process of correcting walking posture through the structure and working principle of the hole tube of the present application:

[0053] FIG12 is a cross-sectional view of the installation position of the hole tube 4. As shown in FIG8 and FIG12, the hole tube 4 is arranged at the bottom of the porous gasket extension 31, in the middle of the two ventilation holes 10, around the groove 11, as shown in FIG12, the hole tube 4 includes at least a sealing area 12 (slash line shaded area) composed of elastic plastic, a ventilation area 13 and a ventilation area 14; FIG13 is a schematic diagram of the structure of the hole tube installed on both sides of the sole. As shown in FIG12 and FIG13, the hole tube 4 is installed on both sides of the sole. , symmetrically arranged, as shown in the enlarged view A in Figure 13, when the hole tube 4 is in a non-stressed state, or when the hole tube 4 on any side is pressed downward by the extension 31 of the porous gasket, a safety distance for horizontal movement is set between the plugs 45 installed on the hole tubes on both sides of the sole, so that no collision occurs. As shown in Figures 12, 13, 15, and 17, when the convex sealing ring 452 cooperates with the concave sealing groove 441 without disengagement, the sealing of the gas in the control chamber 44 can be achieved;

[0054] When the perforated tubes 4 on both sides of the sole are pressed downward by the extension 31 of the porous gasket, the two plug-in plugs 45 installed on both sides of the sole collide, the convex sealing ring 452 is separated from the concave sealing groove 441, and the gas in the control chamber 44 leaks out from the plug position.

[0055] As shown in Figure 14, the holes in the air intake section 42 are tangent to the sealing area 12 to close the holes on the air intake. When not stepping on or in a force balance state, the holes in the air intake section 42 are tangent to the sealing area 12, and the holes in the air intake section 42 are surrounded to prevent gas from entering.

[0056] FIG15 is a schematic diagram of the motion state of the hole tube when the force on the sole of the stepping side is unbalanced. When the walking posture is unbalanced or the force on the sole of the stepping side is unbalanced, the extension 31 of the porous gasket is stressed, and the tapered small mouth of the tapered hole on the porous gasket shrinks downward to exhaust air. At the same time, the extension 31 compresses the ventilation hole 10 at its bottom position to partially shrink (as shown by the broken dotted line on the left side of FIG8 ). At the same time, the extension 31 presses the hole tube 4 at the bottom of the stressed side to move downward. As shown in FIG16 , the hole on the air intake section 42 leaves the sealing area 12 Entering the ventilation area 13, the air intake section 42 takes in air. At the same time, the plug 45 on the orifice tube 4 at the position of the force-bearing side moves forward in the horizontal direction within a safe distance and will not collide. Figure 17 is a schematic diagram of the position of the orifice tube and its airflow when the force on the sole of the shoe on one side is unbalanced. The gas in the control chamber 44 will not leak from the plug position. The gas in the control chamber 44 flows through the air horn 46 to produce a sound prompt, thereby prompting or correcting the walking posture. The gas flowing out of the air horn 46 is connected to the nearby ventilation hole 10 through the ventilation area 14 and discharged. In addition, when stepping on the orifice tube 4 to move downward and touch the recovery base 47, the spring contracts. When the stepping force is released, the orifice tube 4 returns to the position in the non-stressed state under the action of the spring (such as the position of the orifice tube in Figure 12).

[0057] When the sole of the foot jumps high or runs, the two sides of the sole are subjected to force. Figure 18 is a schematic diagram of the position structure of the hole tubes on both sides when the two sides of the sole are subjected to force. As shown in Figure 18, the hole tubes 4 on both sides of the sole are simultaneously pressed downward by the extension 31 of the porous gasket. As can be seen from the enlarged view D in Figure 18, the plug-in plugs 45 installed on the hole tubes on both sides of the sole move relative to each other in the horizontal direction exceeding the safe distance and colliding. As can be seen from the EE cross-sectional view in Figure 18, the plug-in plugs 45 installed on both sides of the sole collide to cause the convex sealing ring 452 to extend into the control compartment 44, and the convex sealing ring 452 is separated from the concave sealing groove 441. Figure 19 is a schematic diagram of the airflow direction of the hole tubes on both sides when the two sides of the sole are subjected to force. At this time, The gas in the control chamber 44 leaks out from the positions on both sides of the plug and is discharged through the nearby ventilation holes. The air flow pressure is reduced, and no obvious prompt sound is emitted when flowing through the air horn 46. Therefore, when the walking posture is correct and the two sides are stepped on, no obvious correction prompt sound is emitted. When the stepping force is released, the hole tubes 4 on both sides restore to the position in the non-stressed state under the action of the spring. The convex sealing ring 452 on the plug-in plug that extends into the control chamber 44 restores to the matching position with the concave sealing groove 441 under the action of the return spring 451 to achieve sealing. Preferably, a locking position is set at the end of the plug-in plug 45 to prevent the convex sealing ring 452 that extends into the control chamber 44 from being pulled out of the control chamber 44 by the return spring 451 when it is restored to the position.

[0058] The total area of ​​the openings of the porous gasket is less than 1 / 2 of the total area of ​​the ventilation holes, or is between 1 / 3 and 1 / 2 of the total area, so as to achieve breathability and mainly exhaust air through the ventilation holes to improve the gas environment in the shoe; preferably, when the openings are conical holes, the opening area of ​​the gasket refers to the area of ​​the conical small mouth, and the total area of ​​the ventilation holes of the sole side openings refers to the opening area of ​​the smaller ventilation hole diameter.

[0059] A waterproof, breathable fabric is provided on the outsole surface, at least on the bottom portion corresponding to the porous gasket 3. Specifically, at least the bottom portion of the porous gasket 3 is provided with the waterproof, breathable fabric. FIG20 is a schematic diagram of a porous gasket provided with the waterproof, breathable fabric. As shown in FIG20 , the waterproof, breathable fabric 33 is preferably integrally formed on the concave bottom surface of the porous gasket 3 to achieve a waterproof and breathable sole.

[0060] In addition, at least the arrangement of the total opening area and the cooperation of the shrinkage and closure structure of the tapered holes on the porous gasket can further change the air flow or pressure entering the orifice tube 4.

[0061] The porous gasket of the present application allows the forefoot to be more stably stressed when the shoe is worn, and the one-way discharge of gas inside the shoe also improves the gas environment inside the shoe, ensuring that the soles of the feet are dry, hygienic and healthy. The porous gasket of the present application cooperates with the hole tube structure to achieve the following: when the walking posture is incorrect, the walking posture can be corrected with the sound of the air horn; when the walking posture is correct, no obvious correction prompt sound is issued, thereby cultivating good shoe wearing habits, further extending the service life of the shoes, and ensuring the health of human bones.

[0062] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
