Description

Technical Field

[0001] The utility model relates to the field of insoles, in particular to an anti-collapse insole memory foam. Background Art

[0002] Sports shoe insoles are generally made of foam as the main material. They are soft and have a microscopic pore structure, so they have good sweat absorption and breathability and are very comfortable to wear.

[0003] GB / T 43549-2023 "Static Compression Deformation Test Method for Footwear Insoles" stipulates that the static compression deformation test method for insoles is used to determine the compression deformation resistance of insoles. This is because the pore structure of the foam will be destroyed after the same part of the foam is squeezed for a long time, causing collapse in that part. Taking memory foam as an example, once its pore structure is destroyed, its memory performance will be affected, which will affect the matching between the insole and the shoe cavity and the shock-absorbing ability of the insole for the foot. The purpose of the utility model is to propose a new foam structure to solve the above-mentioned technical problems. Utility Model Content

[0004] The utility model aims to provide an anti-collapse insole memory foam 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 solution: it includes a foam upper layer, a foam lower layer and a sphere, the bottom surface of the foam upper layer is provided with upper cavities in a matrix shape, the top surface of the foam lower layer is provided with lower cavities in a matrix shape, the foam lower layer is located below the foam upper layer, the number and size of the lower cavities correspond to the number and size of the upper cavities, the sphere is placed in a space formed by the upper cavities and the lower cavities, and the volume of the sphere is smaller than the space formed by the upper cavities and the lower cavities.

[0006] In order to optimize the above technical solution, further measures are taken: it also includes protrusions, which are respectively located in the upper hole cavity and the lower hole cavity and are connected to the upper layer and the lower layer of foam to form an integrated structure. During the wearing process, as the insole bends and deforms, the protrusions can drive the ball to creep through friction, causing the ball to roll in the space formed by the upper hole cavity and the lower hole cavity.

[0007] As a further improvement to the above technical solution: the protrusion can press against the sphere to ensure that the protrusion can stably cooperate with the sphere.

[0008] As a further improvement of the technical solution: the size of the protrusions located on the outside of the upper hole cavity and the lower hole cavity is larger than the protrusions located on the inside of the hole cavity and the lower hole cavity. Such a structural design can prevent the ball from running off the track and ensure that the ball is located at the center of the space formed by the upper hole cavity and the lower hole cavity.

[0009] As an improvement to the above technical solution: it also includes a fabric layer, which is bonded to the top surface of the foam upper layer. The fabric layer can improve the comfort of the insole made of foam.

[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 an anti-collapse insole memory foam, which can be used to prepare insoles. The protrusions cooperate with the spheres to support the foot. During wearing, as the insole twists and deforms, the spheres will turn over inside the insole. The same part of the insole is not prone to collapse due to long-term pressure, thereby increasing the service life of the insole. BRIEF DESCRIPTION OF THE DRAWINGS

[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 1-4 The utility model provides an anti-collapse insole memory foam, comprising a foam upper layer 1, a foam lower layer 2, a sphere 3, a protrusion 4 and a fabric layer 5, and the bottom surface of the foam upper layer 1 is provided with upper cavities 101 in a matrix shape.

[0021] The top surface of the foam lower layer 2 is provided with lower cavities 201 in a matrix shape. The foam lower layer 2 is located below the foam upper layer 1 . The number and size of the lower cavities 201 correspond to the number and size of the upper cavities 101 .

[0022] The sphere 3 is placed in the space formed by the upper cavity 101 and the lower cavity 201. The volume of the sphere 3 is smaller than the space formed by the upper cavity 101 and the lower cavity 201. In implementation, the sphere 3 can be made of the same material as the foam or rubber or other foaming materials. The specific material is not a necessary technical feature nor the technical content that the applicant wants to protect. Therefore, it will not be further explained and will not constitute an unclear technical problem. Technicians can choose materials with different compositions according to actual needs in implementation. As long as the above requirements are met, they can be applied without substantial impact on the technical effect.

[0023] The protrusion 4 is respectively located in the upper cavity 101 and the lower cavity 201 and is connected to the foam upper layer 1 and the foam lower layer 2 to form an integrated structure. The protrusion 4 can resist the sphere 3. The protrusion 4 located outside the upper cavity 101 and the lower cavity 201 is larger than the protrusion 4 located inside the cavity and the lower cavity 201.

[0024] The fabric layer 5 is in contact with the top surface of the foam upper layer 1, and quick-drying fabric, bactericidal fabric or deodorizing fabric is preferably used to improve the wearing comfort of the insole.

[0025] Working principle: The foam can be cut into a preset shape and placed directly in the shoe cavity as an insole for use with sports shoes. The sphere 3 and the protrusion 4 in the space formed by the upper cavity 101 and the lower cavity 201 can cooperate with each other to support the foot.

[0026] During the wearer's exercise, the sports shoes will deform and bend, and the insole placed in the shoe cavity will also deform and bend synchronously. During the deformation and bending of the insole, the protrusion 4 can drive the sphere 3 to flip through the friction force, so that the force-bearing position of the sphere 3 in the insole will constantly change, and it is not easy for the same part of the insole to be flattened by external force for a long time, and the collapse of the insole can be suppressed.

[0027] 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.
