Description

Technical Field

[0001] This utility model relates to the field of insole technology, and in particular to a healthy walking aid insole. Background Technology

[0002] Insoles are bottom components located on the inner surface of the shoe cavity that come into contact with the sole of the foot. They play a role in improving the hygiene of the shoe cavity and the comfort of wearing them. Among them, walking assist insoles, as important products that improve foot health and enhance the walking experience, are receiving increasing attention from consumers.

[0003] Traditional walking aid insoles only provide cushioning, but they cannot provide effective support for key areas such as the arch, heel, and metatarsals during long walks or exercise, which can easily lead to foot fatigue or even foot diseases. Therefore, we have proposed a healthy walking aid insole to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing walking aid insoles, which have a single function and can only provide cushioning. They cannot effectively support key parts such as the arch, heel, and metatarsals during long-term walking or exercise, which can easily lead to foot fatigue and diseases. Therefore, this invention proposes a healthy walking aid insole.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A healthy walking assistive insole includes a support layer, a cushioning layer, a breathable layer, and a protective layer. The top of the support layer is bonded to the bottom of the cushioning layer, the bottom of the support layer is bonded to the top of the breathable layer, and the top of the protective layer is bonded to the bottom of the breathable layer. The support layer, cushioning layer, breathable layer, and protective layer form an insole body. A support structure for increasing support is fixedly provided on the top of the support layer, and a massage component for massaging the sole of the foot is fixedly connected to the top of the cushioning layer.

[0007] In one possible design, the support structure includes a first protrusion and a second protrusion, the first protrusion being fixedly sewn to the top of the support layer and located in the heel region, and the second protrusion being fixedly sewn to the top of the support layer and located in the metatarsal region, the tops of both the first protrusion and the second protrusion penetrating the cushioning layer and extending above the cushioning layer.

[0008] In one possible design, a support protrusion is fixedly bonded to the top of the support layer in the arch support area to support the arch of the foot. The top of the support protrusion penetrates the cushioning layer and extends above the cushioning layer.

[0009] In one possible design, a contact layer is fixedly bonded to the top of the buffer layer, the contact layer being made of silver ion antibacterial cloth.

[0010] In one possible design, the massage component includes multiple massage bumps, which are divided into two groups and respectively fixedly disposed on the top of the buffer layer in the forefoot contact area and the arch contact area.

[0011] In one possible design, the breathable layer has multiple breathable holes, and the outer sides of the support layer and the buffer layer each have multiple side holes. The multiple side holes on the support layer and the multiple side holes on the buffer layer correspond to each other and are connected.

[0012] In one possible design, the bottom of the protective layer has multiple anti-slip grooves.

[0013] In this application, when a user uses the health walking assistive insole, the support structure of the support layer plays a role when the foot is subjected to force during walking or standing. The first protrusion located in the heel area, the second protrusion located in the metatarsal area, and the support protrusion located in the arch support area, through the structural design of penetrating the cushioning layer and extending above it, directly provide support to the heel, metatarsal and arch areas. The first protrusion, the second protrusion and the support protrusion effectively disperse the pressure in this area according to the structural characteristics of the human foot, maintain the normal shape of the arch, evenly distribute the foot pressure, reduce the concentration of local pressure, thereby relieving foot fatigue and preventing foot diseases.

[0014] During walking, when the foot lands, the impact force first acts on the contact layer and then is transmitted to the cushioning layer. The cushioning layer is made of materials with good elasticity and shock absorption properties (such as the elastic deformation of materials like EVA and PU), which can absorb the impact force, convert it into its own elastic potential energy and release it slowly, reducing vibration damage to joints such as the knees and hips, and protecting the human joints. As the foot moves, the massage protrusions located in the forefoot contact area and arch contact area at the top of the cushioning layer generate relative movement and compression with the sole of the foot. Under the pressure and movement of the foot, the massage protrusions press and stimulate the acupoints and muscles on the sole of the foot, thereby achieving a massage of the sole of the foot, promoting blood circulation in the sole of the foot, and improving the comfort of use.

[0015] Meanwhile, the heat and moisture generated by the feet can enter the breathable layer through the side holes on the outside of the support layer and the cushioning layer after passing through the contact layer. Under the action of pressure difference, the air is discharged from the inside of the insole through the holes to the outside environment, and exchanges with the outside air, keeping the air inside the insole circulating and avoiding the feet being in a stuffy and humid environment. The contact layer made of silver ion antibacterial cloth further reduces bacterial growth and odor.

[0016] The anti-slip grooves at the bottom of the protective layer are in close contact with the sole. The anti-slip grooves increase the friction between the insole and the sole, and change the roughness and engagement of the contact surfaces, preventing the insole from sliding inside the shoe during walking, thus ensuring the stability and safety of the user while walking.

[0017] Beneficial effects: The healthy walking assist insole described in this utility model provides precise support for different parts of the foot by having a support structure corresponding to the heel area, metatarsal area and arch support area respectively, effectively relieving foot fatigue and preventing foot diseases;

[0018] In this utility model, the health walking assist insole has massage protrusions in the massage component set in the forefoot contact area and the arch contact area, which can massage the sole of the foot during walking, promote blood circulation, and improve the comfort of use.

[0019] In this invention, the contact layer of the health walking aid insole is made of silver ion antibacterial cloth, which has good antibacterial properties and can effectively inhibit bacterial growth. At the same time, the holes in the breathable layer and the side holes on the outside of the support layer can ensure air circulation, keep the feet dry, and reduce odor.

[0020] In this invention, a support structure is used to precisely support the foot in the areas corresponding to the heel, metatarsals, and arch, relieving walking fatigue and preventing disease. Massage bumps are located in the area where the forefoot and arch meet, massaging the soles of the feet and promoting blood circulation while walking. The contact layer uses silver ion antibacterial cloth to inhibit bacteria, and combined with the breathable layer holes and the side holes of the support layer, it ensures air circulation and keeps the feet dry and odor-free.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1: Refer to Figure 1-3An insole comprises a support layer 1, a cushioning layer 2, a breathable layer 3, and a protective layer 4. The support layer 1 is made of high-strength and resilient EVA material, providing stable support for the foot. Its top is bonded to the bottom of the cushioning layer 2 using environmentally friendly hot melt adhesive. During bonding, the hot melt adhesive is evenly applied to the top of the support layer 1, and then the cushioning layer 2 is adhered. Heating and pressure are then applied to firmly bond the two together. Similarly, the bottom of the support layer 1 is bonded to the top of the breathable layer 3 using environmentally friendly hot melt adhesive, ensuring a tight and stable connection between the layers.

[0027] The cushioning layer 2 is made of memory foam, which has excellent cushioning performance and resilience, effectively absorbing the impact of walking. The top of the cushioning layer 2 is fixedly bonded to the contact layer 5, which is made of silver ion antibacterial cloth and is bonded with low-temperature adhesive to ensure the bonding effect while avoiding the impact of high temperature on the performance of the silver ion antibacterial cloth.

[0028] The breathable layer 3 is made of mesh fabric with multiple evenly spaced ventilation holes 12 to enhance the breathability of the insole. The top of the breathable layer 3 is bonded to the bottom of the support layer 1, and the bottom is bonded to the top of the protective layer 4 using environmentally friendly hot melt adhesive. The protective layer 4 is made of wear-resistant rubber material, and the bottom has multiple anti-slip grooves 10 to increase friction with the sole and prevent the insole from slipping.

[0029] The support structure includes a first protrusion 6, a second protrusion 8, and a support protrusion 7. The first protrusion 6 and the second protrusion 8 are made of the same EVA material as the support layer 1 and are sewn onto the top of the support layer 1 using a sewing machine. The first protrusion 6 is located in the heel area, and the second protrusion 8 is located in the metatarsal area. Both protrusions penetrate the cushioning layer 2 and extend above it. During the sewing process, the sewing position and depth are strictly controlled to ensure that the first protrusion 6 and the second protrusion 8 are firmly connected to the support layer 1 and are accurately positioned.

[0030] The support protrusion 7 is made of high-density sponge and is fixedly glued to the arch support area at the top of the support layer 1 with strong adhesive. Its top also extends through the cushioning layer 2 and above the cushioning layer 2. When attaching the support protrusion 7, first apply adhesive to the corresponding position on the support layer 1, then accurately place and press the support protrusion 7 to ensure a firm bond.

[0031] This application can be used in the field of insole technology, or in other fields applicable to this application.

[0032] Example 2: Reference Figure 1-2An improvement upon Embodiment 1: A health-enhancing walking insole, applied in the field of insole technology, comprises a massage component consisting of multiple massage protrusions 11 made of silicone material, offering good elasticity and comfort. The massage protrusions 11 are divided into two groups, respectively fixed with adhesive to the forefoot contact area and arch contact area on top of the cushioning layer 2. During installation, adhesive is precisely applied according to the ergonomically designed positions, accurately attaching the massage protrusions 11 to the cushioning layer 2, ensuring that the massage protrusions 11 will not fall off during use and can effectively massage the soles of the feet.

[0033] The ventilation holes 12 on the breathable layer 3 are formed by die stamping during the production of the mesh fabric, ensuring that the ventilation holes 12 are evenly distributed and of uniform size. The multiple side holes 9 on the outer side of the support layer 1 and the buffer layer 2 are processed by laser cutting. The multiple side holes 9 on the support layer 1 and the multiple side holes 9 on the buffer layer 2 correspond to each other and are connected, ensuring that air can flow smoothly and achieve good breathability.

[0034] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
