Abstract
Description
Technical Field
[0001] This application relates to the field of footwear, and more particularly to an elastic insole. Background Technology
[0002] As components that come into direct contact with our feet, insoles cover a wide area, almost completely conforming to the sole of the foot, and perform multiple functions such as support, slip resistance, and shock absorption. However, most existing insoles on the market currently use a multi-layered material design. While this design meets the basic requirements of insoles to some extent, it still falls short in terms of overall performance in terms of support, breathability, elasticity, and slip resistance. Specifically, these insoles may experience slow rebound, reduced slip resistance, and poor breathability during use, affecting wearing comfort and safety.
[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0009] The anti-slip layer is made of elastic material and is integrally connected with the shock-absorbing and rebounding layer. The anti-slip layer forms the pad surface of the elastic insole, and the surface is provided with anti-slip patterns. The anti-slip patterns are arranged in an alternating pattern and surround to form a number of breathable holes.
[0010] The cushioning and rebound layer is made of elastic material and is thicker than the anti-slip layer. The cushioning and rebound layer forms the base of the elastic insole.
[0011] The support layer is integrally connected to the interior of the cushioning and rebound layer and is located in the arch area of the elastic insole. The hardness and toughness of the support layer are greater than those of the anti-slip layer and the cushioning and rebound layer.
[0012] In some embodiments, the elastic material is TPU material.
[0013] In some embodiments, the TPU material has a hardness of 65A-75A.
[0014] In some embodiments, the anti-slip layer, the shock-absorbing and rebounding layer, and the support layer are integrally printed.
[0015] In some implementations, the support layer uses PLA material.
[0016] In some embodiments, the shock-absorbing and rebounding layer has a plurality of cubic structures, and the cubic structures are hollowed out from each other.
[0017] In some embodiments, the anti-slip texture forms a mesh structure, and the vent holes are mesh holes.
[0018] In some embodiments, the support layer has a first protrusion extending toward the ball of the foot area of the elastic insole, and two second protrusions extending toward the sides of the heel area of the elastic insole, respectively, with a recess between the second protrusions to accommodate the heel.
[0019] In some embodiments, the support layer has a forefoot support portion extending from both sides of the midfoot toward the forefoot of the elastic insole, the forefoot support portion continuing to the toes, or further extending to the front of the insole.
[0020] In some embodiments, the support layer has two second protrusions extending to both sides of the elastic insole heel area and continuing to extend along the periphery of the heel, forming a closed loop at the heel.
[0021] In some embodiments, the elastic insole further includes an elastic protrusion that has elastic deformation capability and protrudes from the surface of the elastic insole, the elastic protrusion being used to support the concave area of the sole of the foot.
[0022] (III) Beneficial Effects
[0023] Compared with the prior art, the beneficial effects of the technical solution provided in this application include at least the following:
[0024] The elastic insole of this application offers multiple advantages in use. First, the anti-slip layer, with its anti-slip texture, effectively enhances slip resistance during wear, improving safety while walking or exercising. Simultaneously, these anti-slip textures not only fulfill their anti-slip function but also form ventilation holes. This design, while maintaining the necessary support of the anti-slip layer, greatly improves the insole's breathability, making it more comfortable to wear and reducing foot dampness and odor.
[0025] Secondly, the anti-slip layer and the shock-absorbing rebound layer are made of elastic materials, and the thickness of the shock-absorbing rebound layer is greater than that of the anti-slip layer. This feature allows the insole to provide rebound force during use, effectively reducing the impact on the feet when walking or running, and improving wearing comfort and exercise efficiency.
[0026] Furthermore, the support layer is cleverly placed inside the cushioning and rebound layer. Utilizing its own hardness and toughness, it supports the arch area and effectively disperses pressure on the sole of the foot, thereby significantly improving the support performance and stability of the insole. This design is especially important for people who stand or walk for long periods of time.
[0027] Finally, the elastic insole of this application maintains a high degree of simplicity in its overall structure, which not only reduces the difficulty and cost of production, but also makes the insole lighter and more portable, and easier for daily use and cleaning maintenance.

[0046] See Figures 1 to 6 As shown, Figure 1 This is a top view of the elastic insole in an embodiment of this application. Figure 2 This is a schematic diagram of the internal structure of the elastic insole in an embodiment of this application. Figure 3 yes Figure 1 Cross-sectional view of section A in the middle.

[0047] Insoles are in closer contact with our feet than soles, almost completely covering the entire foot, and also serve the functions of support, slip resistance, and shock absorption. Currently, existing insoles are mainly made of multiple layers of materials, which are insufficient in terms of comprehensive performance consisting of breathability, elasticity, and slip resistance.
[0048] To solve the above-mentioned technical problems, this embodiment provides an elastic insole, such as... Figure 1 and Figure 2 As shown, it includes: anti-slip layer 1, shock-absorbing and rebounding layer 2, and support layer 3.
[0049] The anti-slip layer 1 is made of elastic material and is integrally connected with the cushioning and rebound layer 2. The anti-slip layer 1 forms the surface of the elastic insole. The surface of the anti-slip layer 1 has anti-slip patterns 11, which are arranged in an alternating pattern and form several ventilation holes 12. Compared with the traditional anti-slip patterns 11 arranged in a straight line, the alternating pattern of these anti-slip patterns 11 can both form ventilation holes 12 and ensure a certain degree of elasticity and support.
[0050] The cushioning and rebound layer 2 uses elastic material and is thicker than the anti-slip layer 1. The cushioning and rebound layer 2 forms the bottom of the elastic insole and is mainly used for support and to provide rebound force to achieve shock absorption.
[0051] The support layer 3 is integrally connected to the interior of the cushioning and rebound layer 2 and is located in the arch area of the elastic insole. The hardness and toughness of the support layer 3 are greater than those of the anti-slip layer 1 and the cushioning and rebound layer 2.
[0052] When the above-described elastic insole is used, the anti-slip layer 1 achieves a good anti-slip effect through the anti-slip texture 11; simultaneously, the anti-slip texture 11 forms ventilation holes 12, which improve breathability; the anti-slip layer 1 and the cushioning and rebound layer 2 use elastic materials, and the thickness of the cushioning and rebound layer 2 is greater than that of the anti-slip layer 1, which can provide a better rebound effect during use; the support layer 3 is located inside the cushioning and rebound layer 2, and can better support the arch area through its own hardness and toughness, improving support performance; equally importantly, the overall structure of the elastic insole is simple and easy to manufacture. It can be seen that the above-described elastic insole achieves improved breathability, elasticity, and anti-slip performance, bringing users a more comfortable, safe, and efficient wearing experience, with overall performance significantly superior to traditional insoles.
[0053] Understandably, the thickness and shape of the anti-slip layer 1 and the shock-absorbing rebound layer 2 in different areas of the elastic insole can be adaptively adjusted according to the shape of the human foot to achieve a comfortable and safe use.
[0054] For example, the elastic material is TPU. TPU, or thermoplastic polyurethane, is a thermoplastic elastomer with excellent properties. TPU has excellent elasticity and abrasion resistance, can withstand large deformations and recover quickly, and resists wear and cutting.
[0055] Furthermore, the TPU material has a hardness of 65A-75A. Currently, the printed TPU used in the market generally uses 85A-95A material, which results in an effect that is too hard, making it uncomfortable to wear and providing a poor experience. TPU material of 65A-75A, which has a hardness of 70A, has moderate hardness, providing both sufficient elasticity and a certain degree of support, thus improving the comfort of elastic insoles.
[0056] In one embodiment where the anti-slip layer 1, the shock-absorbing and rebounding layer 2, and the support layer 3 are integrally connected, the anti-slip layer 1, the shock-absorbing and rebounding layer 2, and the support layer 3 are integrally printed. Compared to existing bonded insoles, this method is simpler and more efficient to manufacture, and it also improves the durability of elastic insoles.
[0057] In some embodiments, the support layer 3 uses PLA material. PLA, or polylactic acid, is a biodegradable thermoplastic derived from renewable resources such as corn starch, sugarcane, and cassava roots. PLA has good physical properties, such as high transparency, moderate heat resistance, good mechanical strength, and good toughness.
[0058] To further enhance rebound and breathability, the cushioning and rebound layer 2 features several cubic structures 20 with open spaces between them. The cubic structures 20 can be integrally molded as protrusions on the bottom of the cushioning and rebound layer 2, and the spacing between them allows for greater elastic deformation space, thereby improving rebound capability and enhancing breathability at the bottom of the insole.
[0059] For example, the anti-slip textures 11 form a grid structure, and the ventilation holes 12 are grid holes. The grid holes can be triangular, square, or other shapes.
[0060] To improve the support effect of support layer 3, please refer to... Figure 1 , Figures 7 to 10 As shown, Figure 7 This is a schematic diagram of the first embodiment of the support layer in this application. Figure 8 This is a schematic diagram of the second embodiment of the support layer in this application. Figure 9 This is a schematic diagram of the third embodiment of the support layer in this application. Figure 10This is a schematic diagram of the fourth embodiment of the support layer in this application. The support layer 3 is provided with a first protrusion 31 extending towards the foot area of the elastic insole. The first protrusion 31 is used to support the area between the arch and the foot. The support layer 3 is also provided with two second protrusions 32 extending towards both sides of the heel area of the elastic insole. The second protrusions 32 are used to support both sides of the area between the heel and the arch. A concave portion 33 is provided between the second protrusions 32 to accommodate the heel, so as to better fit the shape of the foot and improve the stability of the insole's support for the foot.
[0061] For example, the support layer 3 has a forefoot support portion 34 extending from both sides of the midfoot toward the forefoot of the elastic insole. The forefoot support portion 34 continues to extend to the toes or further to the front of the insole. This arrangement can support the area between the arch and the forefoot, and balance the force on the foot, achieving a more stable support effect.
[0062] For example, the support layer 3 has two second protrusions 32 extending to both sides of the elastic insole heel area, which continue to extend along the outer periphery of the heel and form a closed loop at the heel. The closed loop can wrap around the bottom of the heel to achieve a stable support effect.
[0063] For example, such as Figure 8 and Figure 9 As shown, the support layer 3 has two second protrusions 32 extending towards both sides of the elastic insole heel area, continuously extending along the outer edge of the heel and forming a closed loop at the heel. This closed loop wraps around the bottom of the heel, achieving a stable support effect. Figure 10 As shown, the second protrusion 32 can also be arranged in an open manner around the concave portion 33 to meet the usage requirements of special heels such as large heels.
[0064] In some embodiments, the elastic insole further includes an elastic protrusion 35, see reference Figure 11 and Figure 12 As shown, Figure 11 This is a schematic diagram of the first embodiment of the elastic protrusion in this application. Figure 12 This is a schematic diagram of the second embodiment of the elastic protrusion in this application. The elastic protrusion 35 has elastic deformation capability and protrudes from the surface of the elastic insole, that is, it is located on the inner surface of the elastic insole. The elastic protrusion 35 is used to support the concave area of the sole. The specific location of the elastic protrusion 35 can be determined by analyzing the foot model to identify possible uneven pressure points on the foot due to arch height (high arch, low arch, normal). Based on the analysis results, specific elastic protrusions 35 can be added to key parts of the insole (as shown in the figure) to provide support or cushioning. The height, shape, and position of the elastic protrusion 35 are customized according to individual foot type. The personalized design of the elastic protrusion 35 can be further optimized through gait analysis data such as joint movement and plantar pressure distribution dynamic biomechanical data to improve exercise efficiency or alleviate physical discomfort.
[0065] For example, such as Figure 11 As shown, the elastic protrusion 35 is located in the area connecting the ball of the foot and the toes, and its shape is a crescent or scimitar shape adapted to the connecting area. Figure 12 As shown, another elastic protrusion 35 can be provided on the inside of the big toe to further enhance the cushioning and support effect of the forefoot and toe area.
[0066] For example, the elastic protrusion 35 may also be provided in the arch area, heel area, or area between the heel and arch as needed.
[0067] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
