Description

Technical Field

[0001] This application relates to an insole, and more particularly to a composite insole. Background Art

[0002] An insole is an important part of a shoe and can serve multiple purposes, including comfort in daily wear and height enhancement.

[0003] In existing insoles, for the sake of wearing comfort, a support block is often provided in the arch area to support the foot. However, the support block is mostly in an integral form. When the foot is worn in the wrong position, although the arch area can deform, due to the fixed shape of the support block, when the deformation degree is too large, a repulsive force is likely to be generated, resulting in uncomfortable wearing. Summary of the Utility Model

[0004] The embodiments of this application provide a composite insole to solve the problems existing in the related art. The technical solutions are as follows:

[0005] The embodiments of this application provide a composite insole, including:

[0006] An insole body, with anti-slip patterns on both the heel part and the forefoot part of the insole body;

[0007] A support block, which is arranged on the heel part of the insole body. The support block has through holes adapted to the anti-slip patterns, and the support block has a notch, and the notch is communicated with the through holes.

[0008] In one embodiment,

[0009] The insole body includes:

[0010] An intermediate layer, with convex parts on both the heel part and the forefoot part of the intermediate layer, and the anti-slip patterns are arranged on the convex parts;

[0011] A bottom layer, with through holes adapted to the convex parts opened on the bottom layer, and the bottom layer is attached to the side of the intermediate layer with the convex parts;

[0012] A surface layer, which is attached to the side of the intermediate layer away from the bottom layer.

[0013] In one embodiment,

[0014] The support block is made of a hard material, and the side of the support block has an arc-shaped protrusion.

[0015] In one embodiment,

[0016] The thickness of the convex part of the heel part is greater than that of the convex part of the forefoot part.

[0017] In one embodiment,

[0018] There is a height difference between the anti-skid teeth arranged at intervals on the anti-skid pattern.

[0019] In one embodiment,

[0023] In one embodiment,

[0024] The surface is made of cloth.

[0025] In one embodiment,

[0026] The surface of the surface layer has fine lines.

[0027] In one embodiment,

[0028] When the raised portions of the heel and forefoot of the middle layer are embedded in the through holes, the raised portions on the heel and the raised portions on the forefoot are located on the same plane.

[0029] The advantages or beneficial effects of the above technical solution at least include:

[0040] In the following text, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0041] Figures 1-3 Structural diagram of a composite insole 100 according to an embodiment of the present application is shown. As Figures 1-3 shown, the insole may include:

[0042] Insole body 110, and anti-slip patterns 111 are provided on both the heel part and the forefoot part of the insole body 110;

[0043] Support block 120, the support block 120 is disposed on the heel part of the insole body 110, the support block 120 has through holes adapted to the anti-slip patterns 111, the support block 120 has a notch 121, and the notch 121 communicates with the through holes.

[0044] In this embodiment, the support block 120 and the insole body 110 are integrally formed by heating. When the insole body 110 is placed inside the shoe, the anti-slip patterns 111 are attached to the inner bottom surface of the shoe to prevent the insole body 110 from slipping inside the shoe. The support block 120 is disposed at the insole body 110 to support the insole body 110 and support the heel. By providing a notch 121 on the support block 120, the notch 121 communicates with the through holes. When the heel part of the insole body 110 deforms, the support block 120 can be deformed through the setting of the notch 121, improving the comfort of the heel part of the insole body 110;

[0045] By providing a support block 120 at the insole body 110, the support block 120 supports the heel, reducing the pressure on the heel during walking. At the same time, it can also correct the heel part to a certain extent. By providing through holes and notches 121 on the support block 120, when the heel part of the insole body 110 deforms, the deformation of the support block 120 can be more complete, and there will be no repulsive force during deformation, which affects the comfort of wearing the insole.

[0046] As Figures 2-3 shown, in one embodiment,

[0047] The insole body 110 includes:

[0048] An intermediate layer 112, with raised portions 1121 on both the heel part and the forefoot part of the intermediate layer 112, and anti-slip patterns 111 are provided on the raised portions 1121;

[0049] A bottom layer 113, with through holes adapted to the raised portions 1121 opened on the bottom layer 113, and the bottom layer 113 is attached to the side of the intermediate layer 112 with the raised portions 1121;

[0050] A surface layer 114, and the surface layer 114 is attached to the side of the intermediate layer 112 away from the bottom layer 113.

[0051] In this embodiment, the bottom layer 113 and the support block 120 are integrally formed by heat bonding. The through holes on the support block 120 correspond to the through holes on the heel part of the bottom layer 113. The bottom layer 113 has through holes adapted to the notches 121, facilitating the positioning of the support block 120. The two raised portions 1121 on the intermediate layer 112 respectively pass through the through holes on the heel part and the forefoot part and are flush with the surfaces of the support block 120 and the forefoot part of the bottom layer 113, and the surface layer 114 is in contact with the human body.

[0052] As Figures 2-3 shown, in one embodiment,

[0053] The support block 120 is made of a hard material, and the side of the support block 120 has an arc-shaped protruding portion.

[0054] In this embodiment, the support block 120 is made of PU material, which can deform when subjected to pressure, improving the comfort of the insole body 110. The side of the support block 120 has an arc-shaped protruding portion, making the sides of the bottom layer 113, the intermediate layer 112, and the surface layer 114 all form arc-shaped protruding portions. When the insole is used, the arc-shaped protruding portions support the user's heel part.

[0055] As Figure 1 and Figure 3 shown, in one embodiment,

[0056] The thickness of the raised portion 1121 at the rear heel is greater than that of the raised portion 1121 at the forefoot.

[0057] In this embodiment, the thickness of the rear heel is greater than that of the forefoot. When the intermediate layer 112 is connected to the bottom layer 113 and the support block 120, it ensures the flushness of the bottom surface of the bottom layer 113 and the support block 120. At the same time, it makes the resilience of the rear heel higher than that of the forefoot, thereby improving the support for the heel.

[0058] Furthermore, since the pressure borne by the rear heel is relatively greater than that of the forefoot, the thickness of the raised portion 1121 at the rear heel is set to be greater than that of the forefoot. The thickness of the raised portion 1121 on the forefoot and the rear heel can also be adjusted according to requirements.

[0059] The material of the raised portion 1121 is PU (polyurethane) material, and the density is 60 / m 3 ~120 / m 3 , having high resilience and ensuring the comfort of wearing.

[0060] Such as Figure 1 and Figure 3 shown, in one embodiment,

[0061] There is a height difference between the anti-slip teeth arranged at intervals on the anti-slip pattern 111.

[0062] In this embodiment, there is a height difference between adjacent anti-slip teeth on the anti-slip pattern 111. When the raised portion 1121 contacts the sole, the higher anti-slip teeth fit with the sole, so that a gap is formed between the lower anti-slip teeth and the sole, facilitating the passage of air and enhancing the breathability of the sole.

[0063] When the raised portion 1121 is under pressure, the higher anti-slip teeth are deformed by the downward pressure, so that the lower anti-slip teeth contact the sole.

[0064] In one embodiment,

[0065] The bottom layer 113 is made of SEBS material.

[0066] In this embodiment, the SEBS material is a thermoplastic elastomer, full name Styrene EthyleneButylene Styrene, having good stability and aging resistance, and at the same time having plasticity and high elasticity. It can be processed and used without vulcanization, and is integrally formed with the support block 120 in a thermoplastic form through high temperature.

[0067] In one embodiment,

[0068] The intermediate layer 112 is made of PU material.

[0069] In this embodiment, the middle layer 112 is made of PU (polyurethane) material, which has high resilience and enhances the comfort of the insole.

[0070] In one embodiment,

[0071] The surface layer 114 is made of cloth.

[0072] In this embodiment, the surface layer 114 contacts the foot, and the surface layer 114 is set to be a cloth material to improve the skin-friendly feeling of the insole and improve the comfort when wearing.

[0073] In one embodiment,

[0074] The surface of the surface layer 114 has fine lines.

[0075] In this embodiment, the surface of the surface layer 114 has fine lines. When the shoe is worn, the surface layer 114 contacts the foot, and the fine lines enhance the friction between the foot and the skin to avoid slipping.

[0076] If Figure 1 and Figure 3 As shown, in one embodiment,

[0077] When the raised portions 1121 on the heel and forefoot of the intermediate layer 112 are embedded in the through holes, the raised portions 1121 on the heel and the raised portions 1121 on the forefoot are located on the same plane.

[0078] In this embodiment, when the raised portions 1121 on the heel and forefoot of the middle layer 112 are embedded in the through holes, the raised portions 1121 on the heel and the raised portions 1121 on the forefoot are located on the same plane, which facilitates the placement of the insole and the inside of the shoe, and at the same time, the insole surface layer 114 has a certain curvature, thereby supporting the foot and relieving the pressure on the foot.
