Description

Technical Field

[0001] This invention relates to the field of insole technology, and more specifically to an anti-slip layer combination insole. Background Technology

[0002] Insoles are the part of a shoe that is in closest contact with the foot. They are soft pads used to absorb the weight of the body and the force and reaction force generated by the foot and the ground when walking. Existing insoles are usually made of cotton or fiber blends, but these materials will gradually compress and collapse with use, losing their shock absorption function.

[0003] Existing insoles are typically made of EVA low-foam material, cut and then bonded with a layer of anti-slip fabric. These insoles have a fixed shape, with only minor adjustments based on shoe size, making them unsuitable for all users. They are uncomfortable to wear, and due to fit issues, they tend to shift inside the shoe, sometimes even slipping out from the heel. This shifting not only increases discomfort but also causes the anti-slip fabric to peel off. When part of the anti-slip fabric peels off, it curls and folds, affecting comfort. When all the anti-slip fabric peels off, only the EVA material remains, losing its friction-increasing function and increasing the risk of injury during use. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an anti-slip layer combination insole, with the aim of providing an adaptive insole that offers advantages such as anti-slip layer and enhanced comfort.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] An anti-slip layer combination insole includes an anti-slip sleeve, a support body, and an elastic block. The support body has a cavity inside, and the elastic block is located inside the cavity. The anti-slip sleeve includes an anti-slip surface layer and an anti-slip edging. The anti-slip surface layer is connected to the upper surface of the support body. One end of the anti-slip edging is fixedly connected to the anti-slip surface layer, and the other end surrounds the support body downwards. The opening of the anti-slip edging is constricted and located below the support body.

[0007] Conventional insoles are prone to delamination due to two main reasons: weak adhesion and exposed adhesive edges. Friction between the adhesive edges and the inner layer of the shoe causes the seams to detach. After the seams detach, friction from the foot causes the anti-slip fabric to curl and fold, which worsens over time. In this invention, the anti-slip surface layer is bonded to the support body using an edge-wrapping process. The anti-slip edge wraps downwards around the support body, providing stronger connectivity and preventing the anti-slip surface layer from curling. Furthermore, the anti-slip edge surrounds the support body, creating a seamless look and making it less prone to delamination.

[0008] In addition, the support body of the present invention has a receiving cavity, and an elastic block is provided in the receiving cavity. The elastic block can effectively support the support body. The elastic block is replaceable, which can meet the needs of most consumer groups. This allows the present invention to reduce shock and reduce the pressure on the knees when running and walking, making it more comfortable to use.

[0009] Furthermore, the anti-slip surface layer is a fiber-woven fabric, and the anti-slip edging is a ring-shaped sheet made of TPU material and fiber-woven fabric, with an outer contour consistent with the shape of the anti-slip surface layer, and the outer ring of the anti-slip edging is fixedly connected to the anti-slip surface layer.

[0010] Furthermore, the anti-slip edging is a sheet-like structure made of fiber textile tape and TPU material, and the fiber textile tape and the anti-slip surface layer are an integral structure.

[0011] The anti-slip surface layer uses fiber textile fabric because it has excellent sweat-wicking and breathability, quickly transferring foot sweat, keeping feet dry, and improving comfort. The anti-slip edging uses TPU material and fiber textile fabric to maintain the integrity of the anti-slip cover and extend its service life. On the other hand, TPU is a high-quality elastic material, and the composite material formed by the fiber textile fabric as a reinforcing material is more wear-resistant and tear-resistant. In addition, TPU also has anti-slip properties. When it comes into contact with the TPU-made sole, it has excellent anti-slip effect, keeping the insole stable inside the shoe and preventing it from shifting outward.

[0012] Furthermore, the support is made of TPU material and includes an upper piece, a lower piece, and a connecting piece. The upper and lower pieces have the same shape, and the projection of the upper piece on the horizontal plane surrounds the projection of the lower piece on the horizontal plane. The upper and lower pieces are connected by the connecting piece, and the space between the upper and lower pieces is a receiving cavity.

[0013] The support body provides the same level of slip resistance when in contact with the anti-slip edging, preventing delamination of the anti-slip surface layer adhesive seam due to relative movement between the anti-slip edging and the support body. Furthermore, even if there is some separation between the anti-slip surface layer adhesive seam and the support body, the anti-slip fabric is prevented from curling due to the wrapping effect of the edging, thus preventing further delamination of the adhesive seam and avoiding delamination between the anti-slip surface layer and the support body. The support body has a two-piece structure with a connecting piece in the middle. The reasonable design of the shape and structure of the support body reduces the difficulty of processing and also provides a certain thickness for the insole, providing a certain degree of elastic shock absorption.

[0014] Furthermore, the connecting piece is inclined to connect the upper piece and the lower piece, and the length direction of the connecting piece is set along the length direction of the insole. The inner ends of the receiving cavities on both sides of the connecting piece overlap vertically. The upper end of the connecting piece corresponds to the middle of the outer longitudinal arch of the foot, and the lower end corresponds to the middle of the inner longitudinal arch of the foot.

[0015] The inclined connecting piece deforms more noticeably when stepped on, and the deformation is not concentrated between the upper and lower pieces. This prevents a noticeable bulge from forming in the middle of the support when stepped on, thus ensuring more comfortable use. The connecting piece, which is set along the length direction, restricts the relative sliding of the upper and lower pieces, limiting their relative stability within a certain range and preventing excessive slippage that could lead to movement risks.

[0016] As living standards gradually improve, people are paying more and more attention to the function of insoles. Insoles that not only need shock absorption but also have other health benefits such as sweat absorption, antibacterial properties, or arch support are more popular. However, the existing arch support insoles on the market are all fixed structures, simply raised at the arch based on shoe size. But people's arches are different; some have flat feet, and some have high arches. The simple arch support insoles on the market cannot meet the needs of most consumers. To make insoles fit one's arch, professional customization is required, which is expensive and time-consuming. Apart from professional athletes, it is difficult for other consumers to accept insole customization.

[0017] Furthermore, the elastic block has an air cavity filled with gas, and the elastic block is provided with a partition, which has a vent hole.

[0018] Furthermore, the air volume in the air chamber is 90% to 95% of the maximum volume of the air chamber.

[0019] The partition is a diaphragm connected to the inner wall of the air chamber or a pressing line formed by pressing the inner walls of the air chamber together using a hot pressing method. The elastic block is used for support and shock absorption. The air chamber filled with gas is compressible and can effectively absorb energy and absorb shock, reducing the impact on the legs and knees caused by running or exercise. The partition with ventilation holes in the air chamber can slow down the gas flow speed in the air chamber, giving the air chamber damping characteristics, thereby providing a better shock absorption effect. The multiple partitions are inclined in different directions, which also has the function of limiting the relative sliding of the upper and lower walls of the elastic block.

[0020] Furthermore, the support body is evenly distributed with square holes penetrating the upper and lower surfaces of the support body, and the upper and lower surfaces of the support body are provided with crisscrossing grooves in a mesh pattern, the grooves connecting to the square holes, and the upper and lower surfaces of the elastic block are provided with limiting parts, the limiting parts extending into the square holes.

[0021] The limiting part extending into the square hole can further restrict the movement of the elastic block and prevent the invention from deforming during use. In addition to limiting the movement of the elastic block, the square hole also serves as a ventilation channel. The elastic block deformed by stepping will change the volume of the receiving cavity. The elastic block with changed volume will draw in or expel air through the square hole, causing the gas inside the shoe to flow and increasing the ventilation effect of the shoe. At the same time, it can also evaporate the sweat absorbed by the anti-slip surface, keeping the shoe dry. The dry shoe environment can inhibit bacterial growth. Compared with the insoles of the prior art, the present invention has stronger ventilation and breathability.

[0022] The limiting part can not only restrict the movement of the elastic block, but also position the elastic block at different positions depending on the position of the limiting part extending into the square hole, so as to meet the needs of different groups.

[0023] Furthermore, the limiting part includes a jump plate and a limiting ball. In its natural state, the jump plate is a spherical crown shell with its opening facing away from the elastic block and its spherical arch facing the elastic block. The spherical outer surface of the jump plate is fixedly connected to the outer wall of the elastic block, and the limiting ball is fixedly connected to the center of the spherical inner wall of the jump plate.

[0024] When the elastic block is compressed, it contacts the inner wall of the cavity. At this time, one end of the square hole is closed, making it difficult for gas to flow. The pop-up disc has the characteristic of bulging outward under pressure and returning to its original shape due to the deformation of its own material after pressure is released. During walking or running, it can increase the amount of gas flow in the square hole, so that the whole invention has gas flow, further improving the ventilation and breathability of the invention. The inflation volume of the elastic block of the invention is 90% to 95% of the maximum volume of the air cavity, which can meet the usage conditions of the pop-up disc.

[0025] Furthermore, the elastic block can be a one-piece structure or a split structure.

[0026] Furthermore, when the elastic block is an integral structure, the shape of the elastic block is consistent with the shape of the upper and lower pieces, and the center of the elastic block is provided with a fitting hole for fitting over the connecting piece.

[0027] The integrated structure allows the elastic block to be fitted over the connecting piece and restrained by the connecting piece. When the elastic block is stepped on, it cannot detach from the upper and lower pieces. Although the present invention does not use adhesive to connect the elastic block and the cavity between the upper and lower pieces remains open, the elastic block will not move outward due to the limiting effect of the limiting part. This means that the elastic block and the support body of the present invention do not delaminate.

[0028] The elastic block has an air cavity. When the integrated elastic block is stepped on, because the whole is interconnected, the air in the air cavity at the position of the heel and the ball of the foot will transfer to the arch of the foot. This causes the upper piece at the corresponding arch position to be lifted by the elastic block, forming a curved surface that fits the sole of the foot. This invention enables the upper piece with the anti-slip surface layer to fit completely against the user's sole, so that the foot pressure is evenly distributed, fatigue is reduced, and the comfort of use is improved. It avoids the defects of insoles on the market that cannot generally meet the needs of consumers, and does not require the high cost and long cycle of professional customization.

[0029] Because the integrated elastic block of this invention can redistribute gas under pressure, ensuring that every point on the sole of the foot is evenly stressed, the integrated structure can also be used for medical orthopedic correction. For example, O-shaped or X-shaped legs caused by foot eversion or inversion, as well as foot membrane inflammation caused by fear of external impact or prolonged walking, can all cause people to have strange postures when walking or standing. After using this invention, the shock absorption and pressure-bearing sinking effect of the gas can contain the defects in the affected area, thereby reducing the defects and preventing them from being reflected in the posture of walking or standing, making body management twice as effective.

[0030] Furthermore, when the elastic block is split, the elastic block is composed of a first bladder, a second bladder, and a third bladder. Each of the first, second, and third bladders has an air cavity. The first bladder is located at the position corresponding to the calcaneus on the insole. The second bladder is located at the position corresponding to the middle of the foot on the insole. The middle of the second bladder is provided with a fitting hole for fitting over the connecting piece. The third bladder is located at the position corresponding to the transverse arch to the metatarsal bone on the insole.

[0031] Insoles must be used in conjunction with shoes in daily life. Except for shoes with hidden height-increasing insoles, shoe designs usually do not have a very high inner cavity. Therefore, for the sake of comfort and universality, the thickness of insoles usually cannot exceed 10mm. Insoles that are too thick will increase the difficulty of wearing shoes.

[0032] The split structure can better meet different needs. For example, consumers who run a lot and require high shock absorption can use a thicker, more airy, and more elastic cushioning block to increase the shock absorption effect in the heel. Consumers who stand a lot can use the first and third bladders with less air and the second bladder with more air to balance the pressure on the feet during long periods of standing. Women who wear high heels need the first and second bladders with less air and the third bladder with more air to reduce excessive pressure on the soles of the feet caused by wearing high heels. Because the air in the split structure does not transfer within the first, second, and third bladders, the support and shock absorption effect on a specific area is more obvious.

[0033] The beneficial effects of the present invention through the above technical solution are as follows:

[0034] After the anti-slip surface layer of this invention is bonded to the support body, an edge-wrapping process is used, with the anti-slip edge wrapping downwards around the support body. This provides stronger connectivity, preventing the anti-slip surface layer from curling up, and also creates a sense of unity by surrounding the support body, making it less prone to delamination. The elastic blocks effectively support the support body, enabling this invention to absorb shock, reduce knee pressure during running and walking, and make it more comfortable to use. The anti-slip surface layer has excellent sweat-absorbing and breathable properties, quickly transferring sweat from the feet, keeping the feet dry, and improving comfort. The anti-slip edge uses TPU material and fiber textile fabric to maintain the integrity of the anti-slip cover, increase its service life, and provide excellent anti-slip properties, keeping the insole stable inside the shoe and preventing it from shifting outwards.

[0035] The inclined connecting piece of this invention deforms more significantly when stepped on, and the deformation does not concentrate between the upper and lower pieces, thus avoiding the formation of a noticeable bulge in the middle of the support when stepped on. This makes it more comfortable to use. The connecting piece, which is set along the length direction, restricts the relative sliding of the upper and lower pieces, keeping the relative stability of the upper and lower pieces within a certain range, and avoiding excessive slippage of the upper and lower pieces that could lead to movement risks.

[0036] The elastic block of the present invention has the function of ventilating and breathing the insole, enhancing the air flow inside the shoe, increasing the ventilation and breathability of the shoe, and at the same time evaporating the sweat absorbed by the anti-slip surface layer, keeping the shoe dry. The dry insole environment can inhibit bacterial growth. The present invention has stronger ventilation and breathability than the insoles of the prior art.

[0037] The elastic block of the present invention provides comprehensive support for the sole of the foot and can be combined according to different needs to correct specific physiological defects. Attached Figure Description

[0046] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0047] Example 1:

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, an anti-slip layer combination insole includes an anti-slip sleeve 1, a support body 2, and an elastic block 3. The support body 2 has a receiving cavity 4 inside, and the elastic block 3 is inside the receiving cavity 4. The anti-slip sleeve 1 includes an anti-slip surface layer 5 and an anti-slip edging 6. The anti-slip surface layer 5 is connected to the upper surface of the support body 2. One end of the anti-slip edging 6 is fixedly connected to the anti-slip surface layer 5, and the other end surrounds the support body 2 downwards. The opening of the anti-slip edging 6 is constricted and located below the support body 2. In simple terms, the anti-slip sleeve 1 forms a downward-opening pouch-like structure. The inner cavity of the anti-slip sleeve 1 contains the support body 2, and the support body 2 contains the elastic block 3. The anti-slip sleeve 1, the support body 2, and the elastic block 3 form a combined structure.

[0049] The anti-slip surface layer 5 is a fiber-woven fabric with a certain degree of elasticity. On the one hand, it is for moisture-proof and sweat-absorbing purposes, and on the other hand, the fabric can effectively prevent slipping when in contact with socks. The anti-slip edging 6 is a ring-shaped sheet made of TPU material and fiber-woven fabric, with an outer contour that matches the shape of the anti-slip surface layer. That is, a thin layer of TPU material is coated on the outside of the fiber-woven fabric. The outer contour of the anti-slip edging 6 is the same as the outer contour shape and size of the support body 2. The outer ring of the anti-slip edging 6 is fixedly connected to the anti-slip surface layer 5.

[0050] like Figure 4As shown, the support 2 is made of TPU material. Both the support 2 and the anti-slip edge 6 have a higher proportion of rigid segments than flexible segments in their TPU material, exhibiting good elasticity. TPU material is thermoplastic polyurethane elastomer rubber. TPU is a polymer material formed by the reaction and polymerization of diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with macromolecular polyols and low-molecular-weight polyols (chain extenders). TPU possesses excellent high tensile strength, high tensile strength, toughness, and aging resistance. It is a mature environmentally friendly material with unparalleled strength, toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, and weather resistance compared to other plastic materials. Simultaneously, it exhibits high waterproofness and breathability, windproofness, cold protection, antibacterial properties, mildew resistance, and warmth retention. It has many excellent functions such as UV resistance and energy release; by changing the ratio of each reactive component of TPU, products with different hardness can be obtained, and as the hardness increases, the product still maintains good elasticity. The support body 2 is mainly used as a foot support, which needs to have a certain toughness and good deformation ability to conform to the shape of the foot. The TPU of this invention is non-foamed. The non-foamed TPU material can produce elastic deformation when squeezed to avoid injury to the foot. When stepped on for a long time, it will not produce permanent plastic deformation. The support body 2 includes an upper piece 7, a lower piece 8 and a connecting piece 9. The upper piece 7 and the lower piece 8 have the same shape. The projection of the upper piece 7 on the horizontal plane surrounds the projection of the lower piece 8 on the horizontal plane. The upper piece 7 and the lower piece 8 are connected by the connecting piece 9. The space between the upper piece 7 and the lower piece 8 is the receiving cavity 4.

[0051] The connecting piece 9 is inclined to connect the upper piece 7 and the lower piece 8. The connecting piece 9 is an arc-shaped or long strip-shaped sheet. The length direction of the connecting piece 9 is generally set along the length direction of the insole. The inner ends of the receiving cavities 4 on both sides of the connecting piece 9 overlap vertically. The upper end of the connecting piece 9 corresponds to the middle of the outer longitudinal arch of the foot, and the lower end corresponds to the middle of the inner longitudinal arch of the foot.

[0052] The elastic block 3 has an air cavity 10 filled with gas. The elastic block 3 is provided with a partition 11, and the partition 11 is provided with a vent hole 12.

[0053] The partition 11 and the vent 12 enable the distribution of gas flow within the elastic block 3 while also providing damping characteristics, thereby achieving a shock absorption effect.

[0054] The support body 2 has square holes 13 that penetrate the upper and lower surfaces of the support body 2. The upper and lower surfaces of the support body 2 are provided with crisscrossing grooves 14 in a mesh pattern. The grooves 14 are connected to the square holes 13. The upper and lower surfaces of the elastic block 3 are provided with limiting parts 15, which extend into the square holes 13.

[0055] like Figure 5As shown, the elastic block 3 is an integral structure. The shape of the elastic block 3 is consistent with the shape of the upper piece 7 and the lower piece 8. The elastic block 3 has a fitting hole 16 in the middle for fitting over the connecting piece 9.

[0056] In this embodiment, the elastic block is formed by blow molding TPU, followed by molding and cutting. The lower end of the blow-molded tubular TPU is clamped to form a closed shape. Gas is stored inside the tubular TPU and extends downward. After extending to a sufficient length, the two sides of the tubular TPU are pressed together by a mold. The inside of the mold is the pressing line, and the edge of the mold is the cutting line. After the two molds are closed, the cutting line separates the elastic block inside the mold from the tubular TPU. The pressing line is joined to form a partition on the elastic block. The TPU at the discontinuous part of the pressing line does not form a connection, thus forming a vent hole on the pressing line. The space between the cutting line and the pressing line of the mold does not contact, so the cavity formed between the two layers of TPU is the air cavity, which contains the gas from the blow molding process.

[0057] This embodiment is universally applicable to everyone because the integrated elastic block 3 is interconnected. When stepped on, the gas in the air chamber 10 at the position of the heel and the ball of the foot will transfer to the arch of the foot, thereby causing the upper piece 7 at the corresponding arch position to be lifted by the elastic block 3, forming a curved surface that fits the sole of the foot. This invention enables the upper piece 7 with the anti-slip surface layer 5 to fit completely against the user's sole, so that the foot pressure is evenly distributed, fatigue is reduced, and the comfort of use is improved. It can achieve the effect of professional customization at low cost, avoiding the defects of insoles on the market that cannot generally meet the needs of consumers, and eliminating the need for the high cost and long cycle of professional customization.

[0058] Because the integrated elastic block of this invention allows the gas to flow and distribute under pressure, ensuring that every point on the sole of the foot is evenly stressed, it is especially beneficial for special populations. Therefore, the integrated structure is suitable for medical orthopedic correction, such as O-shaped or X-shaped legs caused by foot eversion or inversion, foot membrane inflammation caused by fear of external impact or prolonged walking, which can all cause people to have strange postures when walking or standing. After using this invention, the shock absorption and pressure-bearing sinking effect of the gas can contain the defects in the affected area, thereby reducing the defects and preventing them from being reflected in the posture of walking or standing, making body management twice as effective.

[0059] Example 2:

[0060] This embodiment is basically the same as Embodiment 1, and the same parts will not be repeated. The difference is as follows:

[0061] like Figure 6As shown, the elastic block 3 has a split structure, consisting of a first bladder 17, a second bladder 18, and a third bladder 19. Each of the first bladder 17, the second bladder 18, and the third bladder 19 has an air cavity 10. The first bladder 17 is located at the position corresponding to the calcaneus of the insole, the second bladder 18 is located at the position corresponding to the middle of the foot, and the second bladder 18 has a fitting hole 16 in the middle for fitting over the connecting piece 9. The third bladder 19 is located at the position corresponding to the transverse arch to the metatarsal bone of the insole.

[0062] The split structure of this embodiment can better meet different needs and is universally applicable. It also has a good match for people with special requirements for insoles. For example, consumers who run a lot and have higher requirements for shock absorption can use the elastic block 3 with thicker walls, more air, and better elasticity to increase the shock absorption effect in the heel. Consumers who stand a lot can use the first bladder 17 and the third bladder 19 with less air, and the second bladder 18 with more air to balance the foot pressure after standing for a long time. Female consumers who wear high heels need the first bladder 17 and the second bladder 18 with less air, and the third bladder 19 with more air. Because the air in the split structure does not transfer inside the first bladder 17, the second bladder 18, and the third bladder 19, the support and shock absorption effect for a specific part is more obvious.

[0063] Example 3:

[0064] This embodiment is basically the same as Embodiment 1 and Embodiment 2. Embodiment 3 further enhances its functionality based on Embodiment 1 and Embodiment 2.

[0065] like Figure 7 As shown, the limiting part 15 includes a jump plate 20 and a limiting ball 21. In its natural state, the jump plate 20 is a spherical crown shell with its opening facing away from the elastic block 3 and its spherical arch facing the elastic block 3. The spherical outer surface of the jump plate 20 is bonded or thermally fused to the outer wall of the elastic block 3. The limiting ball 21 is fixedly connected to the center of the spherical inner wall of the jump plate 20.

[0066] This embodiment, while generally applicable, is particularly suitable for people with excessive foot sweat. The invention itself has a ventilation and breathability function. The bouncy plate 20 has the characteristic of bulging outward under pressure and returning to its original shape due to the deformation of its own material when pressure is released. During walking or running, it can increase the air flow in the square hole, further enhancing the ventilation and breathability of the invention and making it more conducive to ventilation and moisture removal. On the one hand, it allows the sweat from the feet to be transferred downward from the anti-slip surface layer 5 and the anti-slip edge 6, preventing sweat from staying on the soles of the feet for a long time. On the other hand, when walking, the bouncy plate 20 can bulge outward and then return to its original shape, similar to the diaphragm of a diaphragm pump reciprocating at one end of the square hole, so that air flow is formed in the square hole 13. This air flow flows through the anti-slip surface layer 5 to form a ventilation effect, which is especially friendly to people with excessive foot sweat.

[0067] The anti-slip surface layer 5 of this invention is a 0.3mm thick double-sided woven quick-drying fabric. The upper piece 7 and lower piece 8 of the support body 2 are both 1.5mm to 2mm thick. The wall thickness of the elastic block 3 is 0.5mm to 1mm. When the elastic block 3 is fully inflated, the internal gas thickness is 4mm to 6mm. The overall thickness of the insole is about 9mm. However, after being stepped on, the thinnest part is 4mm to 5mm thick, and the thickest part can reach 15mm to 20mm locally. This allows the upper surface of the insole to fully conform to the sole of the foot, making it lightweight and comfortable to wear inside the shoe. It is breathable and moisture-wicking, adapts to the shape of the sole of the foot, does not peel off, and does not slip out, making it suitable for use by various consumer groups.

[0068] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made to the technical solutions of the present invention without departing from the spirit of the present invention or the scope of disclosure.
