Abstract
Description
Technical Field
[0001] The utility model relates to the field of shoes, in particular to a shock-absorbing sole with a hollow structure and a shoe containing the shock-absorbing sole. Background Art
[0002] When landing with the heels during running, the feet need to repeatedly bear an impact force equivalent to about 1.5-3 times the body weight. The burden on the lower limbs caused by high-intensity running in a short period of time or accumulated running over time cannot be underestimated. Therefore, shock absorption is one of the most important elements in running shoe design. The purpose of shock absorption is to slow down the speed and amplitude of the ground impact force when the foot contacts the ground.
[0003] However, the human foot undergoes complex periodic posture changes during running. The existing support plate structure is difficult to fully adapt to the movement state of the foot and provide sufficient shock absorption for the foot to reduce the burden on the entire lower limb musculoskeletal system and reduce risks such as osteoarthritis. It is also difficult to simultaneously meet the functional needs of runners in terms of comfort and stability.
[0004] Therefore, designing a sole structure with a hollow structure shock-absorbing function is of great significance for improving the shock-absorbing effect of the shoe and reducing the impact of the ground on the human body when landing. Utility Model Content
[0005] The purpose of the utility model is to provide a shock-absorbing sole with a hollow structure, and a shoe with a shock-absorbing sole with a hollow structure, which can fully adapt to the movement state of the foot by transferring the impact reaction force absorbed by the heel area to the forefoot area through the hollow structure. The specific technical solution is as follows:
[0006] A shock-absorbing sole with a hollow structure, the midsole includes a forefoot area, a midfoot area and a heel area, at least one first hollow channel that can generate elastic deformation is arranged on the midsole to absorb impact reaction force, and the first hollow channel of the midsole is arranged in a direction from the heel area to the forefoot area, so that the first hollow channel guides the impact reaction force absorbed in the heel area to be transmitted to the forefoot area.
[0007] Furthermore, the first hollow channel includes a first free end and a second free end. The first free end is arranged near the heel area of the midsole and penetrates the side of the midsole to form a hole opening backwards, and the second free end is arranged in the forefoot area of the midsole.
[0008] Furthermore, the midsole also includes a second hollow channel, the second hollow channel includes a third free end and a fourth free end, the third free end is close to the inner side and / or outer side of the midsole, and runs through the side of the midsole to form a hole opening backwards, and the fourth free end is arranged in the forefoot area of the midsole.
[0009] Furthermore, the spacing distance between a first hollow channel and an adjacent first hollow channel gradually decreases in the direction from the heel area to the forefoot area, and / or the spacing distance between a first hollow channel and an adjacent second hollow channel gradually decreases in the direction from the heel area to the forefoot area.
[0010] Furthermore, the forefoot region where the second free end of the first hollow channel or the fourth free end of the second hollow channel is located corresponds to the anterior metatarsal joint of the human foot.
[0011] Furthermore, four first hollow channels and two second hollow channels are provided, and the third free ends of the second hollow channels are provided in the midfoot region and / or the forefoot region.
[0012] Furthermore, the first free end of the first hollow channel or the third free end of the second hollow channel passes through the midsole to form an open hole, so that the hot air generated in the forefoot area of the midsole can be discharged outwardly through the hole.
[0013] Furthermore, the hollow channel is filled with an elastically deformable buffer component.
[0014] Furthermore, the width of the hollow channel is set to 5 cm to 10 cm.
[0015] Furthermore, the hollow channel is arranged at any one position of the interior, the upper surface and the lower surface of the midsole.
[0016] A shoe comprises the shock-absorbing sole with the hollow structure described above.
[0017] The shock-absorbing sole and shoe with a hollow structure of the utility model have the following advantages:
[0018] By setting a channel with a hollow structure in the direction from the heel area to the forefoot area in the midsole of the shoe from the rear to the front, the hollow channel can produce elastic deformation. When the human body is running, the heel area first contacts the ground. At this time, the heel will be subjected to the impact reaction force from the ground. The impact reaction force is guided by the hollow channels set vertically in the front and back, and transitions from the heel area of the midsole to the forefoot area as it rolls with the sole of the foot and is gradually released, thereby achieving the effect of reducing the peak ground reaction force and shock absorption, reducing the burden of the impact on the entire lower limb musculoskeletal system, and providing better shock absorption effect.
[0019] In addition, since the hollow channel is set to extend from the heel area to the forefoot area, the impact reaction force is guided to roll and disperse from the heel area to the forefoot area of the midsole, avoiding excessive pressure on local areas, thereby fully adapting to the movement state of the foot and simultaneously improving the comfort and stability of the human body when running. BRIEF DESCRIPTION OF THE DRAWINGS
[0020] Figure 1It is a schematic diagram of the midsole of the shock-absorbing sole with a hollow structure of the present invention.
[0021] Figure 2 It is a schematic diagram of the outsole of the shock-absorbing shoe sole with a hollow structure of the present invention. DETAILED DESCRIPTION
[0022] In order to better understand the purpose, structure and function of the present invention, the shock-absorbing sole with a hollow structure of the present invention is described in detail below in conjunction with the accompanying drawings.
[0023] like Figure 1 and Figure 2 As shown, the shock-absorbing sole with a hollow structure includes a midsole 100 and an outsole 200 arranged on the bottom surface of the midsole 100, wherein the midsole 100 includes a forefoot area, a midfoot area and a heel area which are connected in sequence, and the side of the sole body close to the toes of the human body is defined as the front of the sole body, and the side of the sole body close to the toes of the human body is defined as the back of the sole body, then at least one channel with a hollow structure is arranged on the midsole 100 from the back to the front in the direction from the heel area to the forefoot area, and the hollow channel can produce elastic deformation. When the human body is running, the heel area first contacts the ground, and at this time the heel will be subjected to an impact reaction force from the ground. The impact reaction force is guided by the hollow channels arranged vertically in the front and rear directions, and transitions from the heel area of the midsole 100 to the forefoot area along with the rolling of the sole of the foot and is gradually released.
[0024] Specifically, since the hollow channel of the midsole 100 can be elastically deformed, when the sole of the foot is subjected to impact reaction force, the force deformation of the hollow channel can absorb a portion of the energy generated by the ground impact reaction force, thereby achieving the effect of reducing the peak value of the ground reaction force and reducing shock, and reducing the burden of the impact on the entire lower limb musculoskeletal system. At the same time, the gas in the hollow channel can be compressed and gradually released after the impact. This compression and release process can effectively consume part of the impact force and reduce the direct impact on the foot, thereby providing a better shock absorption effect.
[0025] Furthermore, when running, the human foot first lands on the ground with the heel, and then transitions to the midfoot and forefoot in sequence. This is the most common way of landing when running, especially in long-distance or medium-slow running. This method allows the human body to disperse the impact reaction force of the ground by rolling on the heel, midfoot and forefoot, thereby reducing the pressure on the foot and knee joints. By setting the hollow channel to extend from the heel area to the forefoot area, the impact reaction force is guided to roll and disperse from the heel area to the forefoot area of the midsole 100, thereby avoiding excessive pressure on local areas, fully adapting to the movement state of the foot, and simultaneously improving the comfort and stability of the human body when running.
[0026] In addition, when the heel area of the human body touches the ground and is impacted, the midsole 100 material around the hollow channel will undergo elastic deformation and store energy. As the sole of the foot rolls forward, the stored energy will be gradually released to provide additional power support for the runner. The energy recovery and release of the impact reaction force can enable the human body to get a certain amount of power in each step, thereby reducing the burden on muscles and joints and improving running efficiency.
[0027] In order to better understand the purpose, structure and function of the present invention, the following, in conjunction with the accompanying drawings, takes the specific structure of the shock-absorbing sole with a hollow structure as an example to further describe the shock-absorbing sole with a hollow structure of the present invention and the shoes containing the shock-absorbing sole with a hollow structure.
[0028] like Figure 1 and Figure 2 As shown, the shock-absorbing sole with a hollow structure includes a midsole 100 and an outsole 200 arranged on the bottom surface of the midsole 100, wherein the midsole 100 includes a forefoot area, a midfoot area and a heel area which are sequentially connected, and a side of the sole body close to the inner side of the human foot is defined as the inner side of the sole body, and a side of the sole body close to the outer side of the human foot is defined as the outer side of the sole body, and four first hollow channels 110 and two second hollow channels 120 are arranged on the midsole 100 from back to front, and the interiors of the first hollow channels 110 and the second hollow channels 120 are hollow structures and can generate elastic deformation to guide the impact reaction force absorbed by the rear end to be transmitted forward and gradually released through elastic deformation, and the elastic deformation transitions to the forefoot area with the rolling of the sole of the foot, so as to fully adapt to the movement state of the foot and enhance the comfort and stability of the human foot during movement.
[0029] Specifically, a straight line is drawn between the two midpoints of the inner side and the outer side of the sole, and the straight line is used as the axis of symmetry. Four first hollow channels 110 are relatively symmetrically arranged on both sides. The first hollow channel 110 includes a first free end 111 and a second free end 112. The first free end 111 is arranged near the heel area of the midsole 100 and penetrates the side of the midsole 100 to form a hole that opens backwards, through which part of the impact reaction force can be released, and the heat generated by repeated impacts on the sole during running can be released, thereby improving comfort. Two adjacent first hollow channels 110 in the sole area are kept at a distance, and the impact reaction force from the middle of the sole area is absorbed by the two first hollow channels 110 near the axis of symmetry, and the impact reaction force from the inner side and the outer side of the sole area is absorbed by the two first hollow channels 110 far from the axis of symmetry. The second free end 112 is arranged in the forefoot area of the midsole 100, corresponding to the force generating area of the forefoot area in the extension phase, so as to gradually release the impact reaction force.
[0030] The second hollow channel 120 includes a third free end 121 and a fourth free end 122. The two third free ends 121 are respectively arranged on the inner side and the outer side of the midfoot area adjacent to the forefoot area, and are arranged to penetrate the side surface of the sole to form a hole opening backwards, through which the impact reaction force received by the inner and outer sides during the turning process of the foot and the heat generated by the impact of the inner and outer sides during the turning process can be released. The fourth free end 122 is arranged in the forefoot area of the midsole 100, which also corresponds to the force area of the forefoot area in the extension phase, so as to gradually release the impact reaction force.
[0031] Of course, those skilled in the art can also set any number of hollow channels and spacing methods according to actual conditions, as long as the hollow channels are arranged vertically from back to front, so as to guide the impact reaction force of the heel area to roll forward through the elastic deformation direction of the hollow channels, thereby adapting to the movement state of the foot and simultaneously improving the comfort and stability of the human body when running.
[0032] Furthermore, the spacing distance between the first hollow channel 110 and the adjacent first hollow channel 110, as well as the spacing distance between the first hollow channel 110 and the adjacent second hollow channel 120 gradually decreases in the direction from the heel area to the forefoot area, that is, the first hollow channel 110 and the second hollow channel 120 are arranged to converge from the heel position toward the toe direction, so as to quickly concentrate and transmit the deformation at the heel position to the midfoot and forefoot areas along the above-mentioned hollow channels, so as to release the ground impact reaction force exerted on the heel.
[0033] Preferably, the second free end 112 of the first hollow channel 110 and the forefoot area where the fourth free end 122 of the second hollow channel 120 is located correspond to the anterior metatarsal joint of the human foot to balance the shock absorption and support requirements of the sole. In addition, the position of the anterior metatarsal joint is the maximum force point in the extension phase of the human foot. By centrally arranging the second free end 112 and the fourth free end 122 to this position to conform to the movement state of the human foot, the impact reaction force energy absorbed by the elastic deformation is released at this position, so that the extension of the human body in the forefoot area is maximally assisted, thereby reducing the burden on muscles and joints and improving running efficiency.
[0034] Furthermore, the second free end 112 of the first hollow channel 110 and the fourth free end 122 of the second hollow channel 120 are connected through the midsole 100 to form an open hole, so that the hot air generated in the forefoot area of the midsole 100 can be discharged outward through the hole, thereby achieving a ventilation effect and facilitating reducing the heat problem caused by repeated stepping on the forefoot during running.
[0035] In addition, a ventilation module can be set outside the sole and the ventilation pipe can be inserted into the channel to further increase the heat dissipation and ventilation performance of the running shoes and improve the comfort of the human foot.
[0036] Furthermore, a hollow third channel can be set between the first hollow channel 110 and between the first hollow channel 110 and the second hollow channel 120 according to design and functional requirements, which is equivalent to increasing the overall area and volume of the hollow channel, so that the impact reaction force on the sole area can be quickly dispersed and transmitted through the third channel, and an elastically deformable buffer component can be filled in the above-mentioned channel to change the shock absorption or rebound rolling performance of the shoe. The buffer component can adopt a hard elastomer or other buffering material, which can be adjusted according to the actual design and functional requirements.
[0037] Furthermore, the width of the first hollow channel 110 and the second hollow channel 120 is set to 5cm to 10cm. This width setting can provide the best cushioning effect under the premise that the supporting effect is basically not attenuated. In addition, the longitudinal height cushioning requirement of the first hollow channel 110 and the second hollow channel 120 is set. The higher the channel height, the better the cushioning effect of the running shoe.
[0038] Furthermore, the first hollow channel 110 and the second hollow channel 120 are arranged on the lower surface of the midsole 100, and can also be arranged inside or on the upper surface of the midsole 100. The above settings can absorb part of the energy generated by the ground impact reaction force through the deformation of the hollow channels, thereby achieving the effect of reducing the peak value of the ground reaction force and shock absorption, and reducing the burden of the impact on the entire lower limb musculoskeletal system.
[0039] The midsole 100 of the above-mentioned sole is a foam material, which is made of one, two or more materials selected from nylon elastomer, polyurethane (thermoplastic polyurethane (including aromatic and aliphatic types), cast polyurethane, mixed 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, high styrene rubber, brominated butyl rubber, butadiene rubber, silicone rubber, EPDM rubber, natural rubber, isoprene rubber, nitrile rubber, and chloroprene rubber through supercritical foaming or chemical foaming molding process. It is characterized by a hardness of 40-45C and a density of 0.12-0.18g / cm 3 .
