Description

Shoe pad for preventing chap of sole

Technical Field

The utility model relates to a shoe body structure, in particular to an insole which has better buffer performance and can effectively protect the sole and prevent the chapping of the sole.

Background

Due to seasonal changes or the decline of the health of the middle-aged people, puerpera (postpartum) and other reasons, the blood circulation at the heel of a person is not smooth, the metabolism is slow, and the secretion of sweat glands is not good; in addition, environmental factors such as wind, cold and dry air cause more old people, weak people or people in cold regions to suffer from heel chapping, especially the foot root and half sole parts, and the foot beauty of modern people is affected by the dryness, chapping, heel pain and inconvenience for our life.

At present, except for the medical treatment for foot chap, the most common method is to use a plaster patch to be attached to the cracked affected part, but once the plaster is easily peeled off, the appearance is not good, and the healing is slow. The other one heals and creates a new split. The ointment is also applied to the affected part, but the open application can easily cause the ointment to contaminate shoes and socks and greatly weaken the drug effect. There are some membrane glue type rhagadia prevention socks, which prevent foot rhagadia by wrapping affected part with silica gel layer, but the glue is fixed on socks, which has certain wearing limitation, and considering the structural stability of glue layer forming, it can only be formed on the inner side of relatively thick cotton socks, so it can only be worn in cold and dry winter, and it can feel stuffy and hot in summer, which is very uncomfortable and inconvenient.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to fig. 1 and 2, in the present embodiment, an insole body 1 for preventing chapped foot is shown in fig. 1, the outer side of which is turned outwards by a back cover layer 14 and is used as a covering edge 3 after being adhered, and has four thickened layer regions on the surface, including a first thickened layer 2, a second thickened layer 4, a third thickened layer 5 and a fourth thickened layer 6, corresponding to two sole stress positions of the front sole, a lateral arch stress position and a heel position, respectively, which are positions where the chap of the normal foot is likely to occur. The insole for preventing the chapped sole of the foot can be put into shoes such as leather shoes, sports shoes, cloth shoes and the like as a wrapping and protecting structure to wrap and protect the position where the chapped foot is easy to appear.

In this embodiment, the cross-sectional structure of any thickening layer region including the first thickening layer 2, the second thickening layer 4, the third thickening layer 5, and the fourth thickening layer 6 is the same as that shown in fig. 2, and includes the bottom sheet 12 as the base layer of the insole body, in this embodiment, the bottom sheet 12 is formed of EVA, the base thickness is 3mm, and the thickness of the region corresponding to the four thickening layers of the first thickening layer 2, the second thickening layer 4, the third thickening layer 5, and the fourth thickening layer 6 on the bottom sheet 12 is 5-8 mm, and the thickness continuously decreases from the center of the thickening layer to the outer edge. Blind grooves are formed in the upper and lower surfaces of the four thickening layers, a plurality of pre-holes 10 are formed in the blind grooves, and elastic contraction rings are formed at the outer contour line positions of the blind grooves; in addition, the blind grooves on the upper and lower surfaces of the bottom sheet 12 are filled with silica gel to form an upper silica gel layer 11 and a lower silica gel layer 13, and the bottom surfaces of the blind grooves are formed with rough lines for facilitating the adhesion of the upper silica gel layer 11 and the lower silica gel layer 13. The upper silica gel layer 11 and the lower silica gel layer 13 are connected into a whole at the position corresponding to the pre-opening hole 10, and are in continuous transition with the thickening layer at the outer edge corresponding to the thickening layer. The elastic shrinkage ring surrounds the outer side of the upper silica gel layer 11 and the outer side of the lower silica gel layer 13, and enables the upper silica gel layer 11 and the lower silica gel layer 13 to shrink inwards in an unstressed state.

In this embodiment, the thickness of the lower silica gel layer 13 is uniform and 2 mm; the lower surface of the lower silica gel layer 13 is a plane so as to facilitate the bottom sealing layer 14 to seal the lower surface and perform outer edge wrapping, and in the embodiment, the bottom sealing layer 14 is a cotton cloth layer.

Go up silica gel layer 11 and have the cambered surface of laminating with heel or sole front face stress position in corresponding thickening layer position, go up the thickness of silica gel layer 11 in the thinnest position department that corresponds the thickening layer position and be greater than 2mm in order to guarantee that go up silica gel layer 11 to the parcel nature of the easy chap position of foot. In addition, an elastic mesh fabric layer 8 is formed on the surface of the upper silica gel layer 11, a film layer is adhered to the surface of the elastic mesh fabric layer 8, and a drug slow release layer 9 is formed on the surface of the film layer, in this embodiment, the drug slow release layer 9 is a mixture powder for relieving foot rhagadia and comprising angelica, ligusticum wallichii and safflower components, the surface of the drug slow release layer 9 is sealed by a soft rubber surface layer 7, the soft rubber surface layer 7 is formed by latex or silica gel materials, in this embodiment, the latex is formed by latex materials with better skin-friendly feeling, and the selected latex is softer than the silica gel adopted in the upper silica gel layer 11; meanwhile, a micropore array is formed on the soft rubber surface layer 7 so as to facilitate the release of the drug property in the drug slow-release layer 9.

The insole for preventing chapped foot in this embodiment can be used as a disposable consumable, or can be used as a common insole after the medicine slow-release layer 9 completely releases the medicine property until the upper silica gel layer 11 or the lower silica gel layer 13 deforms and damages.

In another embodiment, the soft rubber surface layer 7 is used as a detachable replacement structure to be detached and replaced, and the insole for preventing chapped feet is more suitable for being used as an insole of sports shoes, wherein a non-woven fabric substrate is formed on the bottom surface of the soft rubber surface layer 7, a non-dry rubber layer is formed on the surface of the elastic mesh-shaped fabric layer 8, and the soft rubber surface layer 7 is adhered to the surface of the elastic mesh-shaped fabric layer 8 on the side of the non-woven fabric substrate, so that the detachable replacement of the soft rubber surface layer 7 can be realized.

Meanwhile, in order to further improve the antibacterial effect of the insole for preventing chapped foot, a chitin spunlace non-woven fabric layer with the thickness not more than 0.2mm can be formed on the surface of the soft rubber surface layer 7 to serve as a bacteriostatic and antiallergic layer to improve the antibacterial performance of the insole.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
