Description

Shoe sole protection sheet {Outsole Reinforcing sheet}

The present invention is a reinforcing sheet formed by weaving a fiber with a high hardness of warp and weft yarn, and relates to a shoe bottom protection reinforcing sheet, characterized in that to prevent damage to the shoe by a pointed object by coupling to the outsole of the shoe. .

In general, the bottom of the shoe is composed of a triple structure divided into outsole, insole, and midsole.

The outsole, the insole, and the midsole are mainly made of synthetic resin such as rubber or silicone, and the midsole is formed with a functional member for the purpose of cushioning shoes.

In general, a shoe should form a cushion between the bottom surface and the foot to absorb the shock applied to the joints of the wearer's feet, knees, spine, and the like, which is formed on the midsole to form the cushion of the shoe. Functional members have been developed from materials such as sponges, and in recent years, it has become common to use an air sole (hereinafter referred to as an air sole) that provides a cushion function to absorb shock.

By the way, the aerosol is generally made of a plastic material, the weight is light, but the durability is weak.

Therefore, when the aerosol, which is a key part of the shoe, steps on a sharp or sharp object while walking, there is a problem that the load of the human body is concentrated and burst despite the small impact.

Indeed, complaints about the quality of shoes due to damage to the aerosols are constantly bursting, and even though the sneakers containing aerosols are expensive, once the aerosols are damaged, repair is almost impossible.

Shoes that have damaged aerosols will hear wind noise whenever you walk, and you will feel uncomfortable walking because of unbalanced walking, so shoes with aerosols should be replaced, no matter how new.

This problem with aerosol-embedded shoes is already widely recognized, and in order to solve this problem, the prior application model 20-0381788 also suggests a method of embedding titanium metal between the outsole and the midsole.

However, the prior application registration utility model has a problem in that it is difficult to apply practically because the built-in metal on the floor greatly damages the elongation (flexibility) to be formed in the shoe when walking, and makes the weight of the shoe heavy and makes the foreigner feel when landing.

An object of the present invention is to provide a reinforcing sheet for protecting the sole of the shoe, which protects the airbag from the impact of the bottom of the shoe with the built-in airbag, and does not impair the flexibility generated in the shoe while walking.

In order to achieve the above object, the present invention is a reinforcing sheet formed by weaving a fiber with a high hardness of warp and weft, shoe soles, characterized in that to prevent the damage of the shoes by a pointed object by coupling to the outsole of the shoe Surface protection reinforcement sheet is the technical subject.

Wherein the fiber is nylon, polyester, Kevlar fiber, glass fiber, cotton, polyethylene (PE), polypropylene (PP), mono-based one or more selected from the fibers of the shoe sole surface protection reinforcement sheet, characterized in that It is preferable.

And the shoe bottom protection reinforcing sheet is preferably a shoe bottom protection reinforcing sheet, characterized in that the adhesive force is formed when the rubber or thermoplastic resin is coated on both sides of the shoe when combined with the outsole.

In addition, the rubber is preferably made of a reinforcing sheet for protecting the shoe sole surface, characterized in that one or more rubber selected from NR, IR, SBR, NBR, IIR, BR, EPDM, CSM rubber.

In addition, the shoe bottom protection reinforcing sheet is particularly preferably coupled to the shoe sole to protect the shoe sole surface, characterized in that to prevent damage to the aerosol formed in the midsole.

The shoe bottom protection reinforcing sheet is preferably a shoe bottom protection reinforcing sheet, characterized in that coupled to the outsole of the shoe to have a slope or weft angle 10 to 80 degrees inclination angle based on the front direction of the shoe. .

According to the present invention protects the airbag from the impact of the bottom surface of the shoe with the airbag built-in, there is an advantage that there is provided a reinforcement sheet for protecting the shoe sole surface without added weight without harming the flexibility generated in the shoe when walking. .

Hereinafter, the present invention will be described with reference to the drawings. In the following description of the present invention, a detailed description of related arts or configurations will be omitted when it is determined that the gist of the present invention may be unnecessarily obscured will be.

The terms to be described below are terms defined in consideration of functions in the present invention, and may be changed according to intentions or customs of users or operators, and the definitions should be made based on the contents throughout the specification for describing the present invention.

In general, the bottom of the shoe is largely composed of the outsole 30 and insole 10, the midsole 20, the cushion of the shoe is mainly formed in the midsole 20.

The cushion of the shoe has been developed from materials such as sponges, and in recent years, it has become common to use aerosols that provide a cushion function to absorb shocks.

However, the aerosol is made of plastic, the weight is light, but the durability is weak. Therefore, the aerosol, which is a key part of the shoe, is easily damaged by a small impact, and the complaints about quality are constantly popping out.

Moreover, despite the high price of sneakers with aerosols, repairs are almost impossible once the aerosols are damaged.

The symptoms of shoes with damaged aerosols are audible every time you walk, and the gait is out of balance, making you feel uncomfortable to walk.

Therefore, shoes with aerosols should be replaced no matter how new shoes are, and in the case of shoes equipped with aerosols, the protection device for the aerosols should be largely provided.

The present invention is a reinforcing fabric of the shoe outsole for protecting the aerosol as described above.

The present invention provides a reinforcement of a mesh structure in which one or more selected fibers from nylon, polyester, kebra fibers, glass fibers, cotton, polyethylene (PE), polypropylene (PP), and mono yarns of high hardness are woven with warp and weft yarns. As a woven fabric, it is bonded to the outsole of the shoe to prevent damage to the shoe by sharp or sharp objects.

In the case of general fabrics, the strength of a sharp or sharp object is weak, so that it is easily punctured and torn, but dense weaving of a hard fiber such as nylon or polyester increases the durability of a sharp or sharp impact.

The present invention as described above to protect the shoes, as shown in Figure 1, the shoe bottom surface protection reinforcement sheet 100 of the present invention is mainly inserted between the outsole 30 and the midsole 20 to form a reinforcement layer. The reinforcing layer thus formed protects the midsole 20 or the aerosol (not shown) formed on the upper layer of the midsole 20.

However, embodiments of the present invention are not necessarily limited thereto, and may be used between the midsole 20 and the insole 10 as necessary, or may be used alone with the outsole 30 and the present invention, and thus without the midsole 20. Lightweight shoe outsoles can also be used.

On the other hand, the reinforcing sheet 100 for protecting the shoe bottom surface of the present invention is coated with rubber or thermoplastic resin on both sides to form an adhesive force when bonded to the outsole, the midsole and the like of the shoe.

In general, the woven reinforcing sheet 101 alone may not be effectively bonded to the outsole 30 in the manufacturing process of the shoe, so that the rubber can be effectively carried out in preparation for the process of adhering to the outsole of the shoe in advance. (Natural rubber) or thermoplastic resin 102 is coated.

Particularly, when the rubber is used to bond the present invention to the outsole 30 or the like as one or more rubbers selected from NR, IR, SBR, NBR, IIR, BR, EPDM, CSM rubber, the rubber base rubber paste is very useful. Since excellent adhesion efficiency is generated, coating natural rubber on both sides of the present invention can improve production efficiency.

In addition, the rubber outsole (30) is made of a high hardness of 70 degrees, but in the case of natural rubber is only 55 degrees of hardness, it produces an excellent buffering effect when bonding with the outsole.

Thus, the present invention is formed as a reinforcing layer on the outsole 30 or midsole 20, insole 10 of the shoe in order to prepare for the sharp or sharp impact generated from the bottom of the shoe.

By the way, even if the present invention is only a woven thin film, since one more layer is formed, it may affect the bending performance of the shoe.

Shoes are equally as flexible as the elasticity of the floor, the flexuralness (elongation) to the folding that occurs during natural walking.

According to the present invention, in order to preserve the flexibility of the shoe, the reinforcement sheet for protecting the shoe bottom surface, as shown in FIG. 4, the inclination 120 or the weft 110 based on the frontal direction of the shoe has an inclination angle of 10 to 80 degrees. To the shoe's outsole.

That is, when the inclination 120 or the weft 110 is formed on the outsole of the shoe so as to be perpendicular or parallel to the front direction of the shoe as shown in FIG. 2, the inclination 120 or the weft 110 when the shoe is bent. The bending distance is limited by the length of) and the flexibility is greatly deteriorated.

However, as in the present invention, the inclination 120 or the weft 110 is inclined in a range of 10 to 80 degrees (ideally, an inclination angle of 45 degrees is most preferable as shown in FIG. 4) based on the front direction of the shoe. When formed so that the elasticity is formed by the weaving net structure formed by the warp and weft yarn as shown in Figure 5, the bendability of the shoe is greatly improved.

The diamond shape shown in FIG. 5 is an exaggerated view of the weaving net formed by the warp yarn 120 and the weft yarn 110, and shows elasticity of the weaving net structure with respect to the direction of force (F, F ') when the shoes are bent. The principle of formation is shown.

As shown in the figure, when the force (F, F ') vector is generated by the bending of the shoe according to the walking of the foot, the bent distance is formed because the diamond structure formed by the warp and weft is relaxed by receiving the force. When the force is lost, it is stretched to the original distance by the restoring force of the diamond structure.

As described above, the present invention improves the durability of the shoe against a sharp object or a sharp object by inserting the woven reinforcing sheet between the shoe's outsole 30 and the midsole 20.

The present invention is a technology that reverses the notion that a woven sheet is generally torn or punctured due to weak strength of a sharp or sharp object, and the sheet is densely woven with fibers of a hard material such as nylon or polyester. It was used as a reinforcing sheet of the sole of a shoe based on the results of experiments that it formed a strong strength on sharp or sharp objects and was not easily damaged.

As such, the present invention has a technical feature of preserving the bending force of the shoe by specifically adjusting the direction of the woven inclination 120 and the weft 110 while reinforcing the strength of the shoe sole.

Embodiments shown for the purpose of the present invention described above are only one embodiment in which the present invention is embodied, and as shown in the drawings, it can be seen that various forms of combinations are possible to realize the gist of the present invention.

Therefore, the present invention is not limited to the above-described embodiments, and various changes can be made by any person having ordinary skill in the art without departing from the gist of the present invention as claimed in the following claims. It will be said that the technical spirit of this invention is to the extent possible.
