Description

Technical Field

[0001] The utility model relates to the technical field of insoles, in particular to a warm-keeping insole. Background Art

[0002] An insole is a pad placed at the bottom inside of a shoe, aiming to provide additional comfort and support. They can usually absorb shock, reduce foot pain and fatigue. The design of insoles takes into account the anatomical structure of the foot, helps correct foot posture, and alleviates problems such as flat feet or high-arched feet. In addition, some insoles also have antibacterial and moisture-absorbing functions, reducing odors and keeping feet dry. Whether for daily wear or sports, suitable insoles can significantly improve the wearing experience and are important accessories to enhance the comfort and functionality of shoes.

[0003] Current insoles are usually divided into several types, including EVA insoles, sponge insoles, cloth insoles, etc. Among them, cloth insoles are the most widely used due to their materials. They can not only have a certain buffering effect but also be washed in time when getting dirty. Compared with sponge and EVA insoles, cloth insoles have a longer service life. However, cloth insoles also have a relatively obvious defect during use. Mainly, after long-term use, under the pressure of the user's weight, the buffering effect of the cloth insole will become worse, and its thickness will also become thinner, resulting in a worse heat insulation and warm-keeping effect of the insole.

[0004] Therefore, a warm-keeping insole is proposed to solve or alleviate the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art and propose a warm-keeping insole.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A warm-keeping insole includes a pad body. The pad body includes a top layer, a bottom layer, and a plurality of elastic strips. A plurality of protrusions are arranged in an array along the length direction on the side of the bottom layer close to the top layer. The protrusions support the top layer, and a plurality of accommodating cavities are formed between the top layer and the bottom layer. The elastic strips are arranged in the accommodating cavities.

[0008] Preferably, the length of the elastic strip is equal to the length of the protrusion, and the elastic strip is made of silica gel material.

[0009] Preferably, both the top layer and the bottom layer are formed into a double-layer structure by warp and weft knitting of a plurality of contact yarns. The double-layer structure includes a surface structure and a lining structure. The surface structure is a reinforced twill structure, and the lining structure is a rib structure.

[0010] Preferably, the surface weave is a 4 - harness satin weave with warp floats and weft sinks. The weave cycle of the surface weave from left to right and from bottom to top is: float - float - sink - sink, sink - float - float - sink, sink - sink - float - float, float - sink - sink - float.

[0011] Preferably, the lining weave is a 4 - harness satin weave with warp floats and weft sinks. The weave cycle of the lining weave from left to right and from bottom to top is: float - sink - float - sink, float - sink - float - sink, sink - float - sink - float, sink - float - sink - float.

[0012] Preferably, the contact yarn includes a core yarn and an outer cladding layer located on its outer circle. The core yarn is formed by twisting profiled cross - section chitin fibers and spandex fibers, and the outer cladding layer is formed by two polyester fibers spirally wound around the outside of the core yarn.

[0013] Preferably, the outer circle of the pad body is turned inwards and a hem is formed by sewing with a suture.

[0014] The utility model has the following beneficial effects:

[0015] Through the design of elastic strips and protrusions, this insole maintains the distance between the top layer and the bottom layer, achieving the effects of temperature insulation and buffering. The chitin fibers provide antibacterial and bacteriostatic functions, and the polyester fibers enhance the structural strength and wear resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A warm insole, as Figure 1 shown, includes a pad body 1. The outer circle of the pad body 1 is folded inward and sewn through a sewing thread 3 to form a seal edge 2, asFigure 2 As shown, the cushion body 1 includes a top layer 101, a bottom layer 102, and a number of elastic strips 104. On the side of the bottom layer 102 close to the top layer 101, a number of protrusions 1021 are arrayed along its length direction. The protrusions 1021 support the top layer 101. A number of accommodation cavities 103 are formed between the top layer 101 and the bottom layer 102. The elastic strips 104 are arranged in the accommodation cavities 103. The length of the elastic strips 104 is equal to the length of the protrusions 1021, and the elastic strips 104 are made of silica gel material.

[0029] As Figure 3 shown, both the top layer 101 and the bottom layer 102 are formed by warp and weft knitting of a number of contact yarns to form a double-layer structure. The double-layer structure includes a surface structure and a lining structure. The surface structure is a reinforced twill structure, and the lining structure is a rib structure. The surface structure has 4 harnesses and the warp floats are floating, and the weft floats are sinking. The tissue cycle of the surface structure from left to right and from bottom to top is: floating floating sinking sinking, sinking floating floating sinking, sinking sinking floating floating, floating sinking sinking floating. The lining structure has 4 harnesses and the warp floats are floating, and the weft floats are sinking. The tissue cycle of the lining structure from left to right and from bottom to top is: floating sinking floating sinking, floating sinking floating sinking, sinking floating sinking floating, sinking floating sinking floating. As Figure 4 shown, the contact yarn includes a core wire 4 and an outer cladding layer 5 located on its outer circle. The core wire 4 is formed by twisting a profiled cross-section chitin fiber 401 and a spandex fiber 402. The outer cladding layer 5 is formed by two polyester fibers 501 spirally wound around the outside of the core wire 4.

[0030] In the actual production of the present utility model, the profiled cross-section chitin fiber 401 in a C shape is obtained by spinning through a spinneret plate, and it is twisted with the spandex fiber 402 through a twisting machine to obtain the core wire 4. Then, two polyester fibers 501 are spirally wound around the outside of the core wire 4 through a covering yarn machine to obtain the contact yarn. Subsequently, the contact yarn is fed into a water jet loom or an air jet loom, and is spray woven through the weaving structures of the surface structure and the lining structure in the double-layer structure to obtain the top layer 101 and the bottom layer 102. A number of protrusions 1021 are formed on the bottom layer 102 through a hot pressing process, and the elastic strips 104 made of silica gel material are bonded into the accommodation cavities 103 formed by the protrusions 1021. Then, the composite bonding between the bottom layer 102 and the top layer 101 is completed, the redundant parts are cut off, and the outer circle is turned inward and sewn through a sewing thread 3 to form a sealing edge 2, obtaining the complete cushion body 1;

[0031] For this insole, by providing the elastic strip 104 and the protrusion 1021, there is a certain distance between the top layer 101 and the bottom layer 102. The air in the accommodation cavity 103 remains in a state of slow flow rate, which can achieve a temperature insulation effect, preventing the low temperature of the ground from being transmitted to the human sole through the shoe sole and the insole. At the same time, due to the provision of the elastic strip 104, the insole has a certain buffering effect and can also slowly return to its original state through the elastic strip 104 when no one is pressing on it. The special-shaped cross-section chitin fiber 401 ensures that the insole has a certain antibacterial and bacteriostatic effect, and it is not prone to mildew and odor. The polyester fiber 501 ensures that the insole can maintain good structural strength and wear resistance and is not easily damaged.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
