Description

insole

This creation is about an insole, especially an insole with a puncture-proof layer that prevents sharp objects from piercing the insole and avoids injury to the soles of the feet.

Generally, in dangerous workplaces, such as construction sites, fields, and forests, there may be sharp objects such as nails, wood chips, and sharp stones on the path that people walk. For safety reasons, avoid staff being stabbed while walking. Sharp objects worn on the soles stab the feet, and those who frequently enter and exit the above-mentioned types of workplaces need to wear work shoes that can prevent puncture.

According to FIG. 1 , a puncture-proof work shoe which is common in the market and can prevent the sole of the foot from being stabbed by a sharp object, as shown in FIG. 1 , includes a sole 11 and an insole 12 in a work shoe 10 and is pre-formed in the inner layer of the sole 11 . A steel sheet 13 is embedded, through which the sharp object is prevented from piercing the insole 12 to achieve the protective effect.

However, according to the above-mentioned conventional method, the puncture-proof work shoes are easily restricted to the type of the shoes, and only the fixed type of shoes have the function of preventing puncture, but the dangerous working environment is not only the construction site, but not only the work. The shoes need to have the effect of preventing puncture. For example, hiking shoes, rain boots, training shoes, etc., are shoes that people who may be in a dangerous environment need to wear, so the above-mentioned steel is pre-embedded in the inner layer of the sole 11 The mechanism by which the sheet 13 protects the sole of the foot is not replaceable and lacks wide applicability for use in various types of shoes.

In view of this, the creator has developed and designed this creation in order to solve the above problems and to deeply conceive and actively research and improve the trial.

Therefore, the main purpose of the present invention is to provide an insole for the wine puncture layer, which can be placed in any kind and style of shoes to prevent the foot from being injured by the sharp object piercing the insole.

In order to achieve the above object, the present invention relates to an insole comprising: a pad body comprising an upper pad and a lower pad; a top layer on the surface of the upper pad, in direct contact with the foot; a puncture prevention a layer, the puncture prevention layer is coated in the pad body; and a glue layer coating and covering the puncture prevention layer for bonding the pad body to the puncture prevention layer.

Wherein, the pad system is a bulletproof cloth.

Wherein, the pad system is a metal piece.

Wherein, the metal piece is in contact with the tibia of the sole of the foot, and has a decompression groove recessed downward for dispersing the pressure of the tibia.

Therefore, the advantage of this creation is that it is not necessary to purchase an additional puncture-proof shoe, and it is only necessary to use the insole provided with the puncture-proof layer, and the pad body can be placed in the shoes worn by the usual work or other dangerous activities, thereby preventing Sharp objects pierce the insole and cause injury to the feet.

The detailed description of the present invention and the technical description are further described in the following examples, but it should be understood that these examples are for illustrative purposes only and are not to be construed as limiting.

Please also refer to Figure 2 to Figure 5. The present invention relates to an insole comprising: a pad body 100 comprising an upper pad 110 and a lower pad 120; a top layer 130, the top layer 130 is located on the surface of the upper pad 110, in direct contact with the foot; a puncture prevention layer 200, the puncture prevention layer 200 is coated in the pad body 100; and a glue layer 300 coating and covering the puncture prevention layer 200 for the pad body 100 and the The puncture resistant layer 200 is bonded.

The pad body 100 is made of moisture wicking, soft and elastic, such as polyurethane (PU), superplastic olefin (EVA), latex and rubber, and covers the pad body 100. The top layer 103 is made of a breathable soft, thin cloth that provides a soft and comfortable touch when the sole is in contact with the insole.

In the implementation, first, the upper and lower surfaces of the puncture prevention layer 200 are coated with a viscous colloid to form a glue layer 300, and the upper pad 110 of the pad body 100 is respectively adhered to the upper surface of the puncture prevention layer 200. The lower pad 120 of the pad body 100 is adhered to the lower surface of the puncture prevention layer 200. In order to prevent the insole from being used for a long time, the adhesive layer 300 loses its viscosity, resulting in the upper pad 110 and the lower pad. 120 is lifted off from the puncture prevention layer 200, and finally the upper pad 110 and the edge of the lower pad 120 which have been bonded to the puncture prevention layer 200 are further subjected to hot pressing to press the upper pad 110 and the lower pad 120. The edges are tightly bonded together, so that the puncture prevention layer 200 is completely covered in the upper pad 110 and the lower pad 120, and is not exposed to the pad body 100, and only needs to be directly adapted to the size of the foot. The pad body 100 can be placed in the shoe 400 worn during work or activities.

Wherein, the puncture prevention layer 200 is a bulletproof cloth, and the fiber of the bulletproof cloth has greater toughness and tensile strength than the general fiber, so the puncture prevention effect is superior to the general insole material, and the thickness is about according to the required puncture function strength requirement. A good anti-puncture effect can be achieved from 1 mm to 4 mm.

Please refer to FIG. 6, FIG. 7 and FIG. 8. Further, the puncture prevention layer 200 is a metal sheet 210. Since the surface of the metal is relatively smooth, in order to avoid the effect of the smoothness of the surface of the metal sheet 210 on the adhesion of the metal sheet 210, the metal sheet 210 must be sandblasted first. The surface of the metal sheet 210 is coated on the metal sheet 210, and the upper surface 110 and the lower surface 120 of the surface of the metal sheet 210 are respectively adhered to the upper and lower surfaces of the metal sheet 210. In the hot pressing manner, the edges of the upper pad 110 and the lower pad 120 are closely adhered, so that the metal piece 210 is completely covered in the upper pad 110 and the lower pad 120, and is not exposed to the outside of the pad body 100.

The metal sheet 210 has a good anti-puncture effect, and only needs a thickness of about 0.3 mm to 0.5 mm to achieve the puncture prevention effect, but the hardness of the metal is high, although the puncture prevention layer 200 made of the metal sheet 210 is Covered in the soft and elastic body 100, but because the sole of the person has a protruding tibia, after a long time standing, running, and walking for a long time, the humerus will suffer from excessive pressure due to the weight of most of the body. The pain, together with the metal sheet, reduces the softness of the body of the pad 100 itself, making it difficult to decompress the tibia. Therefore, further, the metal piece 210 and the foot The bottom humerus contact has a decompression groove 211 which is recessed downward. When the foot is stepped on the pad body 100, the soft pad body 100 is fitted with the foot type depression, and the tibial portion just falls into the metal piece 210. In the decompression tank 211, the pressure for dispersing the tibia is used to reduce the pain of the sole caused by prolonged activities.

Therefore, the present invention inserts the puncture-proof layer 200 into the pad body 100 of the insole, so that the wearer can select a suitable shoe style according to the needs of his work or the active environment, and then put the insole with the puncture-proof effect into the You can use it in your shoes without having to pay for the purchase of shoes with anti-puncture effect.

The present invention has been disclosed in the above preferred embodiments, and it should be understood by those skilled in the art that the present invention is only intended to depict the present invention and should not be construed as limiting the scope of the present invention. It should be noted that variations and permutations equivalent to those of the embodiments are intended to be included within the scope of the present invention. Therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application below.
