Description
Technical Field
[0001] The utility model relates to the field of shoes, in particular to a composite breathable shock-absorbing and rebound structure, and a sole and a shoe containing the composite breathable shock-absorbing and rebound structure. Background Art
[0002] Breathability is very important for running shoes, which can ensure the comfort and health of the feet during running. The breathable performance of running shoes allows air to circulate, helping to discharge the sweat and moisture of the feet, thereby reducing the damp feeling and possible odor of the feet. Good breathable performance can improve the comfort when wearing running shoes. When running, the repeated contraction and relaxation of the foot muscles will generate heat, especially in long-distance or high-intensity running, this heat accumulation is more obvious. If the foot temperature is too high, it may also increase the risk of blisters and abrasions. And due to the factor of gravity, the sweat and the water poured into the shoe from the outside accumulate at the lowest part of the shoe and cannot be discharged in time, affecting the comfort and sports performance, and increasing the risk of illness and injury of the wearer.
[0003] The midsole materials of existing shoes mostly use single materials such as EVA, PU, and PEBAX. Although these materials have certain shock-absorbing and rebound performance, they do not have breathability. Existing running shoes can often only breathe through the upper and the arch of the sole, while the sole under the forefoot and the heel that is repeatedly impacted cannot meet the demand for breathability in order to meet the necessary support, shock-absorbing and rebound performance. This limits the sports performance and comfort of sports shoes, and a material and structure that can replace the midsole of existing sports shoes is needed, which can not only meet the required shock-absorbing and rebound performance, but also achieve good breathable and water-permeable performance. Summary of the Utility Model

[0015] Further, the first ventilation component corresponds to the forefoot and the front side of the midfoot regions of the human foot, and the second ventilation component corresponds to the rear side of the midfoot and the heel regions of the human foot.
[0016] Further, a first region is arranged at the first end and / or the second end of the shock absorption component to reduce the rigidity of the first end and / or the second end of the shock absorption component.

[0038] For a better understanding of the purpose, structure, and function of the present utility model, the composite breathable shock-absorbing and resilient structure of the present utility model will be described in detail below with reference to the accompanying drawings.
[0039] As Figure 1 shown, the composite breathable shock-absorbing and resilient structure includes a rigid shock-absorbing component 100 and an elastic breathable component 200. The composite breathable shock-absorbing and resilient structure can be disposed inside the sole. Define the side of the sole body close to the inner side of the human foot as the inner side of the sole body, and the side of the sole body close to the outer side of the human foot as the outer side of the sole body. The connection direction between the inner side and the outer side is defined as the transverse direction. Then, the shock-absorbing component 100 is a rigid plate with a certain elasticity, including a first end 101 and a second end 102 arranged front and back. At least one downwardly arched concave structure is formed between the first end 101 and the second end 102. The concave structure is preferably an arc-shaped structure. Of course, it can also be a protruding structure with an angular cross-section or an inverted trapezoidal structure, as long as it can adapt to the rolling form of the sole during the pushing stage.
[0040] The breathable component 200 can be made of elastic fabric and is wrapped around the first end 101 and the second end 102 of the shock-absorbing component 100. The surface of the breathable component 200 located on the upper side of the first end 101 and the second end 102 is the top surface 201, and the surface located on the lower side of the first end 101 and the second end 102 is the bottom surface 202. After the breathable component 200 is wrapped around the shock-absorbing component 100, it is in a stretched state, and the two ends of the shock-absorbing component 100 are pulled toward the middle and stretched by the breathable component 200 to enhance the upward support force for the foot. A transversely connected ventilation chamber is formed between the top surface 201 of the breathable component 200 and the concave structure, and air between the sole of the human foot and the breathable component 200 can flow in the ventilation chamber to achieve a breathable effect under the premise that the composite breathable shock-absorbing and rebound structure provides support, shock-absorbing and rebound for the human foot.
[0041] Of course, the breathable component 200 can also be connected only to the two ends of the shock absorbing component 100, so that a transverse ventilation chamber is formed between the top surface 201 of the breathable component 200 and the concave structure. The breathable component 200 can also be in a non-stretched state after being connected to the shock absorbing component 100, and the shock absorbing component 100 can also generate an upward supporting force on the foot by relying on its own curvature.
[0042] Specifically, the breathable component 200 mainly realizes the function of ventilation, and also plays the role of pulling the shock-absorbing component 100 toward the middle and supporting the foot upward. The remaining support and shock-absorbing rebound effect is achieved by the hard shock-absorbing component 100. Since the shock-absorbing component 100 is stretched by the breathable component 200, it is subjected to the force of maintaining the bending arc, thereby providing upward supporting force, and the gap in the middle can well meet the needs of air flow and achieve good breathability.
[0043] When the composite breathable shock-absorbing and rebounding structure is stressed during running, when the breathable component 200 is pressed down, the breathable component 200 pulls the first end 101 and the second end 102 of the shock-absorbing component 100 toward the middle, so that the arc radius of the concave structure is reduced, that is, the concave structure is bent inward, and then the shock-absorbing component 100 absorbs the pressure to play a shock-absorbing role. In addition, the deformation of the shock-absorbing component 100 when it touches the bottom and is pressed will also play a shock-absorbing role. Finally, the stored energy will be applied to the foot and the ground along with the lifting of the foot, playing a rebound role. Therefore, the composite breathable shock-absorbing and rebounding structure can replace the midsole of the existing sole, and can still achieve the functions of ventilation, support, shock absorption and rebound in the core stress area.
[0044] Furthermore, the tension of the breathable component 200 can be adjusted according to the actual shock-absorbing and rebounding requirements. The breathable component 200 can be made of traditional natural fiber materials, artificial synthetic materials, and fabrics made of co-spun materials of natural fibers and synthetic fibers. It is not limited by the material and weaving method of the fabric, and the strength, thickness and mesh size of the breathable component 200 can be adjusted according to actual needs. The connection between the breathable components 200 and between the breathable components 200 and the shock-absorbing component 100 can be fixed by gluing, hot pressing, integrated molding, sewing, mortise and tenoning, nesting, etc.
[0045] In order to better understand the purpose, structure and function of the utility model, the following, in combination with the accompanying drawings, takes the specific structure of the composite breathable shock-absorbing and rebound structure as an example to further describe the composite breathable shock-absorbing and rebound structure of the utility model, and the sole and shoe containing the composite breathable shock-absorbing and rebound structure.
[0046] Embodiment 1, as Figure 1 As shown, the composite breathable shock-absorbing and rebound structure includes a shock-absorbing component 100 and a breathable component 200. The shock-absorbing component 100 includes a first end 101 and a second end 102. The first end 101 corresponds to the toe part of the human foot, and the second end 102 corresponds to the heel part of the human foot. That is, the shock-absorbing component 100 penetrates the entire sole of the foot from front to back and serves as a core force-bearing structure to provide an upward shock-absorbing support effect for the entire sole of the foot, thereby enhancing the overall stability of the sole.
[0047] Among them, the height of the first end 101 is equivalent to the height of the second end 102, and a low point with a height lower than the first end 101 and the second end 102 is set between the first end 101 and the second end 102, thereby making the shock-absorbing structure as a whole a concave structure, which corresponds to the forefoot, midfoot and heel areas of the human foot.
[0048] The breathable component 200 is wrapped around the first end 101 and the second end 102 of the shock-absorbing component 100 in a stretched state. Since the first end 101 and the second end 102 are two relatively high positions of the shock-absorbing component 100, the breathable component 200 and the concave structure between the first end 101 and the second end 102 form a first ventilation chamber 300. The transverse through-type setting of the first ventilation chamber 300 allows air to flow quickly in the first ventilation chamber 300.
[0049] The purpose of providing the above-mentioned shock-absorbing structure is to maximize the space of the first ventilation chamber 300 and achieve maximum breathability in the entire palm area of the sole.
[0050] Embodiment 2, as Figure 2As shown, compared with the first embodiment, the same components include the shock absorption component 100 and the breathable component 200. The shock absorption component 100 includes a first end 101 and a second end 102. The first end 101 corresponds to the toe part of the human foot, and the second end 102 corresponds to the heel part of the human foot.
[0051] Different from the first embodiment, the height of the first end 101 is greater than that of the second end 102. A third end 103 is provided at a position of the shock absorption component 100 close to the heel direction. The height of the third end 103 is equivalent to that of the first end 101 and is also greater than that of the second end 102. A low point with a height less than both of them is provided between the first end 101 and the third end 103. Thus, the shock absorption structure forms a concave structure and a convex structure from front to back. The concave structure corresponds to the forefoot and midfoot regions of the human foot, and the convex structure corresponds to the heel region of the human foot.
[0052] The breathable component 200 is sleeved around the first end 101 and the second end 102 of the shock absorption component 100 in a stretched state. Since the first end 101 and the third end 103 are two relatively high positions of the shock absorption component 100, the breathable component 200 between the first end 101 and the third end 103 forms a second ventilation chamber 301 with the concave structure. The second ventilation chamber 301 is provided with a transverse through-hole, so that air can flow in the second ventilation chamber 301.
[0053] The function of setting the above shock absorption structure is to ventilate and dissipate heat for the second ventilation chamber 301 in the forefoot and midfoot regions. Especially for the forefoot region corresponding to the lowest point of the concave structure, the longitudinal chamber space is the largest to enhance the breathability of the forefoot. The convex structure provides more upward support force to the heel region and enhances the stability of the heel part.
[0054] The second embodiment is for high-level elite runners. During running, they mainly land on the mid-forefoot. Therefore, the most core stress area of the sole is also the main heat-generating area on the sole of the foot. The breathable shock absorption structure is arranged in the forefoot region of the sole to maximize the breathability of the forefoot region.
[0055] Embodiment three, as Figure 3 As shown, compared with the first embodiment, the same components include the shock absorption component 100 and the breathable component 200. The shock absorption component 100 includes a first end 101 and a second end 102. The first end 101 corresponds to the toe part of the human foot, and the second end 102 corresponds to the heel part of the human foot.
[0056] Different from the first embodiment, a fourth end 104 is provided at a position of the shock absorption assembly 100 close to the midfoot area. The height of the fourth end 104 is equivalent to that of the first end 101 and the second end 102. A low point is respectively provided between the first end 101 and the fourth end 104, and between the second end 102 and the fourth end 104. Thus, two concave structures are formed from front to back in the shock absorption structure. The first concave structure corresponds to the forefoot and the front area of the midfoot, and the second concave structure corresponds to the back area of the midfoot and the heel area.
[0057] The breathable assembly 200 is sleeved around the first end 101 and the second end 102 of the shock absorption assembly 100 in a stretched state. At the same time, the breathable assembly 200 also passes through the fourth end 104. The fourth end 104 divides the top surface 201 of the breathable assembly 200 into two parts. Among them, between the fourth end 104 and the first end 101 is the first breathable assembly 200, and the first breathable assembly 200 and the first concave structure form a third ventilation chamber 302. Between the fourth end 104 and the second end 102 is the second breathable assembly 200, and the second breathable assembly 200 and the second concave structure form a fourth ventilation chamber 303.
[0058] The function of setting the above shock absorption structure is to form two breathable chambers in the forefoot and heel areas respectively. The lowest points of the third ventilation chamber 302 and the fourth ventilation chamber 303 respectively correspond to the forefoot and heel areas, so that the longitudinal space of the ventilation chamber corresponding to the lowest point is the largest, thereby increasing the breathability. Especially when the general runners are running, they mainly land on the heel of the foot and then transition from the heel area to the forefoot area to exert force by pedaling. Ventilation and heat dissipation are carried out for the two main stress and heat generation areas of the sole.
[0059] Embodiment 4, as Figure 4 shown, compared with the first embodiment, the same is that it also includes a shock absorption assembly 100 and a breathable assembly 200. The shock absorption assembly 100 includes a first end 101 and a second end 102. The first end 101 corresponds to the toe part of the human foot, and the second end 102 corresponds to the heel part of the human foot.
[0060] Different from the first embodiment, a first area is provided on both sides of the first end 101 and the second end 102 of the shock absorption assembly 100. The first area includes a U-shaped dividing line and an empty groove in the middle of the dividing line. The dividing line of the first end 101 of the shock absorption assembly 100 is provided at the middle position of the first end 101, and the U-shaped opening of the dividing line faces forward, so that the first end 101 forms a first bifurcated structure forward, and / or the dividing line of the second end 102 of the shock absorption assembly 100 is provided at the middle position of the second end 102, and the U-shaped opening of the dividing line faces backward, so that the second end 102 forms a second bifurcated structure backward.
[0061] The function of setting the above-mentioned first region is that the empty slots in the first region reduce the rigidity of the first end 101 and the second end 102 of the shock-absorbing component 100, better dispersing the impact force received by the front and rear ends of the foot when landing. At the same time, the empty slots in this first region can reduce the stiffness of the longitudinal bending of the forefoot and the heel, increase the longitudinal movement space in the middle region between the front and rear ends of the foot, and enhance the flexibility of the turning movement during exercise.
[0062] Furthermore, the empty slots in the first region correspond to the second and third phalanges of the human foot, enhancing the movement space of the second and third phalanges and improving the flexibility of this region of the foot during turning.
[0063] Of course, in addition to setting empty slots in the first region, the rigidity of this region can also be reduced by decreasing the thickness of this region, making the thickness of the first region smaller than that of other positions of the shock-absorbing component 100. As long as the effect of reducing the rigidity of this region can be achieved, the number and shape of the first region can also be selected according to actual needs.
[0064] Example Five, as Figure 5 shown, compared with Example One, the same is that it also includes a shock-absorbing component 100 and a breathable component 200. The shock-absorbing component 100 includes a first end 101 and a second end 102. The first end 101 corresponds to the toe part of the human foot, and the second end 102 corresponds to the heel part of the human foot.
[0065] The difference from Example One is that the breathable component 200 includes a breathable component 200 body, a second region 106, and a third region 107. Among them, the breathable component 200 body refers to the part of the breathable component 200 except for this second region 106 and the third region 107. The second region 106 is arranged corresponding to the forefoot region of the human foot, and the third region 107 is arranged corresponding to the heel region of the human foot. The structural strengths of the breathable component 200 body, the second region 106, and the third region 107 are the first strength, the second strength, and the third strength respectively. The second strength is greater than the first strength, and the third strength is less than the first strength.
[0066] Furthermore, the strength of the second region 106 can be enhanced by pasting or spraying a composite reinforcing material layer on the second region 106. Specifically, materials such as polyurethane, polypropylene, polyethylene, polyamide, polyurea, polytetrafluoroethylene, polyvinylidene chloride, polyolefin resin, ethylene-vinyl alcohol copolymer, and ethylene-octene copolymer can be used.
[0067] Furthermore, the strength of the second region 106 can be enhanced and the strength of the third region 107 can be reduced by setting a number of through holes in the third region 107 or by changing the textile density, structure, etc. of the second region 106 and the third region 107.
[0068] The purpose of setting the above-mentioned second area 106 and third area 107 is to meet the support requirements of the breathable component 200 at different positions of the sole of the human body. Since the forefoot area is subjected to the greatest force during the extension phase of the human body, the structural strength of the second area 106 is increased, and the heel area is subjected to less force, so the structural strength of the third area 107 is reduced accordingly, so as to achieve a balance between the breathability and support requirements of various areas on the sole of the human foot.
[0069] Of course, the number and specific positions of the second area 106 and the third area 107 can also be set in a targeted manner according to the exercise habits of different users, as long as the effect of balancing the breathability and support requirements of each corresponding area can be met.
[0070] Embodiment six, as Figure 6 As shown, compared with the first embodiment, the same thing is that it also includes a shock absorbing component 100 and a breathable component 200, the shock absorbing component 100 includes a first end 101 and a second end 102, the first end 101 corresponds to the toe part of the human foot, and the second end 102 corresponds to the heel part of the human foot.
[0071] Different from the first embodiment, a hard fourth area 108 is set in the middle area of the top surface 201 of the breathable component 200. The fourth area 108 corresponds to the midfoot area of the human foot. The fourth area 108 can adopt the same material as the shock absorbing component 100, that is, a hard plate with a certain elasticity.
[0072] Since the human foot is not a flat surface and different areas are subjected to different forces, by setting the fourth area 108, it is possible to fit different foot shapes under the sole, especially the arch area, and decompose the pressure acting on the arch area to avoid stress concentration, thereby enhancing the overall stability of the foot. The breathable component 200 and the fourth area 108 are spliced together to provide support, ventilation, shock absorption and rebound effects on the sole of the foot.
[0073] Furthermore, a hollow area or a plurality of through holes is provided in the fourth area 108 of the breathable component 200 to reduce the weight of the fourth area 108 and increase the longitudinal air permeability while achieving upward support and avoiding stress.
[0074] Of course, the number and specific positions of the fourth areas 108 can also be set in a targeted manner according to the movement habits of different users, as long as they can fit different foot shapes, decompose downward pressure, avoid stress concentration, and thus enhance the overall stability of the foot.
[0075] Embodiment seven, as Figure 7As shown, compared with Embodiment 3, the same components include a shock absorption component 100 and a ventilation component 200. The shock absorption component 100 includes a first end 101 and a second end 102. The first end 101 corresponds to the toe part of the human foot, and the second end 102 corresponds to the heel part of the human foot. A fourth end 104 is provided at a position of the shock absorption component 100 close to the midfoot area, so that the shock absorption structure forms two concave structures from front to back.
[0076] Different from Embodiment 3, a support and rebound part 400 is arranged in the ventilation chamber. The support and rebound part 400 can be made of a material with support and rebound properties, or can be an air cushion or an elastic plate, etc. The third ventilation chamber 302 is completely filled with a material with support and rebound properties to completely fill the gap of the concave structure and provide higher upward support and rebound performance. In the middle area of the fourth ventilation chamber 303, a part of the material with support and rebound properties is filled, that is, a part of the cavity is reserved to ensure breathability under the sole while providing upward support and rebound performance.
[0077] In addition, a number of elastic particles can also be used to directly fill the gap, and the elastic particles are wrapped with a fabric or a film to prevent scattering.
[0078] Of course, according to the exercise habits of different users, the support and rebound part 400 and its filling ratio can also be set at different positions specifically, as long as the effect of providing higher upward support and rebound performance can be achieved.
[0079] The above-mentioned shock absorption component 100 is arranged corresponding to the toe to the heel of the human foot from front to back to provide shock absorption support for the entire sole. It can also be set only in the forefoot area or the heel area according to specific exercise characteristics or the exercise mode of high-level athletes, or the first end 101 of the shock absorption component 100 can be set at any position corresponding to the toe to the midfoot of the human foot, and the second end 102 can be set at any position corresponding to the midfoot to the heel of the human foot to achieve the effect of targeted ventilation and shock absorption for this area.
[0080] In addition, by using a fabric or fiber material for the ventilation component 200, liquid can pass through the tiny gaps between the materials, so that the sweat on the sole can flow downward through the ventilation component 200 and then be discharged through both sides of the ventilation chamber, achieving the effect of water permeability while ensuring breathability.

[0083] Further, in order to meet the requirements of fitting the foot shape and filling the gap between the structure and the ground surface, some traditional sole materials can be added outside the above structure. It can be made of one, two or more materials selected from nylon elastomer, thermoplastic polyurethane (including aromatic type and aliphatic type), cast polyurethane, millable polyurethane, thermoplastic polyether ester elastomer, ethylene-octene copolymer, ethylene-octene block copolymer, ethylene-vinyl acetate copolymer, styrene-butadiene-styrene block copolymer, hydrogenated styrene-butadiene-styrene block copolymer, polyisobutylene, high styrene rubber, brominated butyl rubber, cis-butadiene rubber, silicone rubber, ethylene propylene diene monomer rubber, natural rubber, isoprene rubber, nitrile rubber, chloroprene rubber, etc., through supercritical foaming or chemical foaming.
