Description

Technical Field

[0001] The utility model relates to shoe materials, and more specifically, to a buffer insole. Background Art

[0002] The insole is padded inside the shoe and is used to cooperate with the outsole and midsole of the shoe to support the sole of the foot, so as to achieve a comfortable support effect for the sole of the foot. Traditional insoles are made of cloth, bamboo, wood, or leather. Limited by the material characteristics, the obtained support effect is limited. With the development of the industry and the needs of sports, etc., improved solutions of making insoles with EVA, sponge, silica gel, TPR, and latex have been adopted, improving the support effect of the insoles.

[0003] Existing insoles are commonly made of a single material or are compounded in a laminated manner with multiple materials. However, the existing insole structure is designed in a single or multi-material pressing and laminating manner, making the structure design relatively simple and difficult to meet the sports needs. During sports, a single structure is difficult to meet the support function for the foot, and after long-term compression and deformation, the buffer effect and support degree also decrease accordingly. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a buffer insole.

[0005] The above technical purpose of the present utility model is achieved through the following technical solutions: A buffer insole includes an integral insole body. Buffer recesses are formed on the bottom surface of the insole body in the forefoot area and the heel area. A buffer sheet with a hollow reticular structure is filled in the buffer recesses. A flank part in the arch area is integrally formed on the side of the insole body. The flank part is used to provide the elastic deformation ability to wrap the arch area.

[0006] By adopting the above technical solutions, in this application, buffer recesses are opened on the integral insole body, so that when the buffer insole is applied to sports scenarios such as running and walking, the buffer of the force application point can be achieved through the deformation of the buffer recesses. Specifically, when the forefoot area and the heel area are stressed, through the easy deformation of the buffer recesses, the air in the buffer recesses can be excluded and deformed after being stressed, and when the deformation is restored, it reacts on the foot, providing an upward acting force to achieve the buffering of the insole. Moreover, a buffer sheet with a hollow reticular structure is filled in the buffer recesses, which improves the support effect while ensuring the deformation ability of the insole body in the forefoot area and the heel area. And the provided flank part can better wrap the arch area of the foot, playing a good supporting and protecting role for the arch of the foot, and avoiding the situation of foot fatigue for the wearer during use.

[0007] Further: The buffer sheet is embedded in the buffer recess and bonded to the insole body. The cross-sectional shape of the hollow reticular structure formed on the buffer sheet is a rhombus structure arranged in an array.

[0008] By adopting the above technical solution, the buffer sheet adopts a diamond structure and is embedded in the buffer recess. Due to the easy deformation of the diamond structure, it can undergo elastic deformation when stressed, expel the air at the hollow part, have a good buffering effect, and ensure good anti-deformation fatigue performance.

[0009] Further: An arch support sheet is provided on the pad body at the outer area and metatarsal arch area of the foot.

[0010] By adopting the above technical solution, by adding an arch support sheet, while ensuring the buffering of the forefoot area and heel area, it can strengthen the support for the arch, achieve the support for the arch during movement, and ensure the force generation of the foot.

[0011] Further: A plurality of groove parts arranged horizontally and vertically are formed on the arch support sheet at the outer area, and support ribs are formed on the arch support sheet at the metatarsal arch area.

[0012] By adopting the above technical solution, the groove parts are arranged on the arch support sheet at the outer area. When the insole is installed in the shoe and subjected to the weight of the foot and the body, the groove parts can increase the contact friction with the shoe, avoid the insole shifting under the action of the generated friction during walking, and the set support ribs can play a supporting role.

[0013] Further: A plurality of the support ribs are arranged in a curve along the length direction of the flank part, and are used to provide a supporting force for the flank part to support the foot in the direction towards the foot at the metatarsal arch area.

[0014] By adopting the above technical solution, the support ribs are arranged in a curve to achieve a better fit with the foot at the metatarsal arch area, and thus play a good supporting force. During walking and movement, it can provide a good supporting effect for the arch part of the foot.

[0015] In summary, the present utility model has the following beneficial effects:

[0016] In this application, by providing buffer recesses on the pad body with an integral structure, when the buffer insole is applied to sports scenarios such as running and walking, the buffer of the force application point can be achieved through the deformation of the buffer recesses. Specifically, when the forefoot area and heel area are stressed, due to the easy deformation of the buffer recesses, the air in the buffer recesses can be expelled and deformed after being stressed, and when restoring the deformation, it reacts on the foot to provide an upward acting force, realizing the buffering of the insole. Moreover, the buffer sheet filled in the buffer recesses has a hollow mesh structure. While ensuring the deformation ability of the pad body in the forefoot area and heel area, the support effect is improved. And the set flank part can better wrap the metatarsal arch area of the foot, play a better supporting and protecting role for the arch of the foot, and eliminate the situation of foot fatigue of the wearer during use.

[0021] The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0022] As Figures 1 to 3 shown, a buffer insole includes an integrally structured cushion body 1. Buffer recesses 2 are formed on the bottom surface of the cushion body 1 and are located in the forefoot area and the heel area. A buffer sheet 3 with a hollow reticular structure is filled in the buffer recesses 2. In this embodiment, the cushion body 1 is made of the existing ESPRO material, which has the functions of damping, energy absorption, and shock absorption, can effectively absorb and disperse the impact force, and plays a good buffering role. Moreover, buffer recesses 2 are formed by recessing on the cushion body 1, which can increase the deformation amount of the forefoot area and the heel area during movement, so as to achieve an increase in buffering performance. When the forefoot area and the heel area are stressed, through the easy deformation of the buffer recesses 2, the air in the buffer recesses 2 can be discharged and deformed after being stressed, and when the deformation is restored, it acts on the foot in the opposite direction, providing an upward acting force to realize the buffering of the insole. On this basis, a buffer sheet 3 made of rubber material is filled in the buffer recesses 2, which can play a good support and buffering effect. In addition, a flank part 4 located in the metatarsal arch area is integrally formed on the side of the cushion body 1. The flank part 4 is used to provide the elastic deformation ability to wrap the metatarsal arch area. The provided flank part 4 can better wrap the metatarsal arch area of the foot, play a better supporting and protecting role for the arch of the foot, and eliminate the situation of foot fatigue when the wearer is using it.

[0023] The buffer sheet 3 is embedded in the buffer recess 2 and bonded to the cushion body 1. The cross-sectional shape of the hollow reticular structure formed on the buffer sheet 3 is a rhombic structure arranged in an array. The buffer sheet 3 adopts a rhombic structure and is embedded in the buffer recess 2. Through the easy deformation of the rhombic structure, it can elastically deform when stressed, discharge the air at the hollow part, has a good buffering effect, and ensures good anti-deformation fatigue performance.

[0024] An arch support sheet 5 is provided on the cushion body 1 and is located in the outer area and the metatarsal arch area of the foot. While ensuring the buffering of the forefoot area and the heel area, it can strengthen the support for the arch, support the arch during movement, and ensure the exertion of the foot.

[0025] The arch support piece 5 is provided with a plurality of groove parts 51 that are horizontally and vertically staggered in the outer region, and a support rib 52 located in the metatarsal arch region is formed on the arch support piece 5. Since the groove parts 51 are arranged on the arch support piece 5 in the outer region, when the insole is installed in the shoe and is subjected to the weight of the foot and the body, the groove parts 51 can increase the contact friction with the shoe, avoiding the situation of insole offset under the action of the friction generated during walking, and the support rib 52 is provided.

[0026] A plurality of support ribs 52 are arranged in a curve along the length direction of the flank part 4, for providing a support acting force in the direction towards the foot in the metatarsal arch region for the flank part 4. The support ribs 52 being arranged in a curve enables them to fit as closely as possible to the foot in the metatarsal arch region, thereby playing a good support acting force. During walking and exercise, it can provide a good support effect on the arch part of the foot.
