Description

Technical Field

[0001] The utility model relates to the field of insoles, in particular to a comfortable high-elastic cotton insole. Background Art

[0002] Sports equipment plays a vital role in the prevention and management of sports injuries. Proper sports equipment can not only improve sports performance, but also reduce the risk of injury.

[0003] Sports shoes are important sports equipment to protect the soles of athletes' feet. When running and jumping, the forefoot is prone to touch the ground alone. When the forefoot touches the ground alone, the pressure of the entire sole of the foot is concentrated on the forefoot, which will cause the muscles, tendons and ligaments to bear a greater load, which not only causes discomfort but also easily leads to sports injuries (an insole with application number 202320824882.8 also mentioned this technical problem in the background technology). The purpose of the utility model is to propose a new insole foam structure to alleviate the above-mentioned technical problems, improve comfort during exercise and reduce the possibility of sports injuries. Utility Model Content

[0004] The utility model aims to provide a comfortable high-elastic cotton insole to solve the problems mentioned in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a foam main body layer, an air cushion layer and a support sheet, the air cushion layer is located on the bottom surface of the foam main body layer and is in contact with the foam main body layer, the support sheet is placed in the air cushion layer, the support sheet includes a connecting part, a pressure-bearing part and a supporting part, the cross-section of the connecting part is semicircular and the two ends of the connecting part are respectively connected to the pressure-bearing part and the supporting part, and the pressure-bearing part is used to bear the forefoot pressure.

[0006] In order to optimize the above technical solution, further measures are taken as follows: slits are formed on the foam main layer, and the slits are distributed in columns and penetrate the foam main layer. The slits can reduce the cross-sectional area of ​​the foam main layer and make the foam main layer easy to bend. At the same time, the slit structure is set on the foam main layer to reduce the deformation of the foam main layer after bending, so as to avoid deformation causing the shoe cavity to be too narrow.

[0007] As a further improvement to the above technical solution: the slit is located at the toe bone portion of the insole, ensuring that the slit corresponds to a portion of the insole that is prone to bending.

[0008] As a further improvement of the technical solution: limiting blocks are formed on both sides of the connecting part inside the air cushion layer, and the limiting blocks press against the connecting part to prevent the limiting part from moving, thereby ensuring that the supporting sheet can function stably.

[0009] As an improvement to the above technical solution: the support part is horseshoe-shaped and can support both sides of the sole. Such a structure allows the support part to support the sole without affecting the cushioning and vibration reduction effect of the foam main layer and the sole on the sole.

[0010] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0011] The utility model provides a comfortable high-elastic cotton insole. When the wearer is in a state of padding the feet or the forefoot is alone on the ground, the support sheet can be tilted up to support the part of the foot that is not on the ground, which can reduce the compression of the forefoot and improve the sports comfort, and can also avoid the occurrence of sports injuries.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] See also Figure 1-4The utility model provides a comfortable high-elastic cotton insole, comprising a foam main body layer 1, an air cushion layer 2 and a support sheet 3. A slit 101 is formed on the foam main body layer 1. The slit 101 is located at the toe bone of the insole. The slit 101 is distributed in columns and penetrates the foam main body layer 1.

[0021] The air cushion layer 2 is located on the bottom surface of the foam main body layer 1 and is in contact with the foam main body layer 1 .

[0022] The support sheet 3 is placed in the air cushion layer 2, and the support sheet 3 includes a connecting portion 301, a pressure portion 302 and a supporting portion 303. The cross-section of the connecting portion 301 is semicircular, and the two ends of the connecting portion 301 are respectively connected to the pressure portion 302 and the supporting portion 303. The pressure portion 302 is used to bear the pressure of the forefoot, and the supporting portion 303 is horseshoe-shaped and can resist the two sides of the sole. Limiting blocks 304 are formed on both sides of the connecting portion 301 inside the air cushion layer 2, and the limiting blocks 304 resist the connecting portion 301 to prevent the limiting portion from moving. The support sheet 3 refers to a sheet-like component that plays a supporting role. The specific material is not the technical content to be protected by the applicant. Failure to disclose its specific material will not lead to unclear technical solutions. Technical personnel can choose different materials while meeting the technical solutions in specific implementation, and hard TPU is preferred.

[0023] Working principle: The foam main layer 1 and the air cushion layer 2 can cushion the foot. Under normal walking conditions, most insoles can fit closely to the foot to ensure that the foot is supported by the insole and the sole.

[0024] When the wearer is in a state of tiptoeing or the forefoot is touching the ground alone, the force on the sole of the foot will be concentrated on the forefoot, and the front pressure-bearing portion 302 of the support plate 3 is squeezed by the forefoot so that the rear support portion 303 is tilted, and the tilted support portion 303 can resist the part of the sole that is not touching the ground, ensuring that the forefoot and the part of the sole that is not touching the ground can be supported when the wearer is in a state of tiptoeing or the forefoot is touching the ground alone, which helps to reduce the strain on the forefoot muscles, tendons and ligaments, improve sports comfort and reduce sports injuries.

[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
