Abstract

The present invention relates to non-slip footwear having a non-slip portion on an inner surface and a non-slip portion on an outer surface and, more particularly, to non-slip footwear which can prevent skin damage while maintaining a non-slip function by staggering a non-slip portion of an inner surface and a non-slip portion of an outer surface.

Description

Non-Slip Footwear

The present invention relates to a non-slip foot garment having non-slip portions respectively provided on the inner surface and the outer surface thereof, and in particular, by disposing the non-slip portions of the inner surface and the non-slip portions of the outer surface so as to prevent skin damage while maintaining the non-slip function. It is about non-slip feet.

The foot is the part of the body that balances the body, supports body weight, and absorbs shock. This is where many blood vessels and nerves pass.

As a means to protect the feet, stockings, tights, oversocks, socks, etc. (hereinafter referred to as "footwear") are used.

In addition to basic protection, foot apparel can also be equipped with additional features such as improved athletic performance, injury prevention, and reduced foot odor through sweat absorption.

Typical foot apparel may have slips on the soles and inner surfaces of the foot garments during use, due to the low coefficient of friction of the selected fiber materials, and on the outer surface of the foot garments and on the inner surfaces of the shoes.

For example, when a woman wears a high-heeled heel (shoe) while wearing a woman's shoes, her weight is forward and her foot is concentrated in front of the shoe, concentrating her toes, resulting in instep, nails, and even shorts. Even muscles can cause pain and stiffness, causing foot fatigue and pain.

Also, as you walk, your feet and tights will slip with your closing force and weight every time you step, and between your tights and your shoes, your toes will be shocked and these shocks will continue to occur while you walk. .

In addition, when the heel is slipped, as the heels are worn, the heel is pulled out and the ankle is easily bent or the gait is unstable, causing an ankle to sprain easily.

According to the report of the Health Insurance Review and Assessment Service, there were 1.6 million patients with ankle sprains in 2010, but it has increased to 1.18 million in 2014.

On the other hand, when looking at sports activities such as running and skating, the wearer's foot slips in the socks when the wearer changes speed or direction during a sports activity or starts or stops quickly, Socks are slipping in shoes.

This is due to the lack of sufficient grip between the feet and the socks, the socks and the shoes.

This lack of sufficient grip will cause sports athletes to injure their ankles and knees.

In an effort to prevent injuries caused by the slip phenomenon as described above and to improve athletic performance, the applicant of the present invention has disclosed "non-slip socks for sports" (Korean Patent Publication No. 10-1686547, Patent Document 1), "for sports Non-slip insole "(Korea Patent Publication No. 10-1638404, Patent Document 2) and the like to apply for registration.

Patent Documents 1 and 2 relate to a cross-sectional structure of a material for enhancing non-slip function in socks and insoles, and a manufacturing method.

As another technique for such a gripping material, the "Construction of a gripping fabric" (US Patent No. 9,498,003, Patent Document 3) is to be formed on the inner surface and the outer surface of the socks, respectively, the anti-slip material, A technique for maximizing athletic ability by allowing the non-slip material of the inner surface and the non-slip material of the outer surface to coincide or overlap each other in the phase is disclosed.

The patent document 3 is a technique for disposing a material for enhancing the non-slip function by maximizing the frictional force of the socks and feet, the contact portion of the socks and shoes when the reference to each point where the slip occurs by overlapping or integrating I will say.

The technique disclosed in Patent Literature 3 manufactures and sells actual socks at a company called True Sox in the United States.

However, when analyzing the reviews of users who actually purchase and use the company's product, there is no difference about the fact that the prevention of slip is increased, but due to the excessive non-slip function, the wearer's foot is injured as shown in FIG. 11. It has been shown that there is a problem that occurs.

This phenomenon occurs when the wearer's feet and the non-slip material of the socks are in good contact with each other during sports activities (the inside non-slip material of the socks and the soles of the socks, and the non-slip material of the socks and the inside of the shoe at the same point). This is because when the weight is loaded at that point, the weight is delivered to the same point, which increases the skin's strength.

At this time, the better the non-slip performance of the non-slip material, the more difficult the skin is subjected to the force.

In particular, since the skin of the sole and the adjacent side of the foot of the wearer is composed of a weaker skin than the sole of the foot, the wound can be more easily caused on the skin.

In addition, when the non-slip material is formed to protrude by the coating or the like at the same point inside and outside of the socks, it gives a foreign body to the foot when worn, and the foreign body is changed into a feeling of pressure due to continuous pressure when worn for a long time. The thinner is, the greater the feeling of foreign body and pressure, which causes the wearer's skin to come in contact with the non-slip material, causing tingling and fever, and severe blisters and wounds.

As described above, as the graphing ability of the anti-slip material is maximized to maximize the athletic performance and prevent the injury caused by the slip phenomenon, there is a need to newly propose an arrangement of the anti-slip material corresponding to the conventional non-slip material. something to do.

Hereinafter, the non-slip feet of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, the inner non-slip portion 10 is formed on the inner surface 1a of the foot garment body 1 in contact with the wearer's foot 2, as shown in FIGS. It relates to a non-slip leg garment having an outer non-slip portion (20) for preventing slipping on the outer surface (1b) of the foot garment body (1) opposite to the inner surface (1a).

The present invention is characterized in that the inner non-slip portion 10 and the outer non-slip portion 20 in the above-described configuration is arranged so as to be non-overlapping with each other when viewed in a plane, that is, when viewed from above or below from above.

As a specific example, referring to FIG. 1, the outer non-slip portion 20 is formed on the outer surface 1b of the foot body 1 but has a lattice shape.

In more detail, the outer non-slip part 20 has a grid portion 30 having a lattice shape in plan view, and a slip portion 40 is formed in an inner space of the grid portion 30. To take.

At this time, the opposite non-slip portion 10 is formed on the inner surface 1a of the foot garment body 1, but the grid portion 30 so as not to overlap the grid portion 30 of the outer non-slip portion 20 in plane. ) Is formed at the position where the slip 40 is formed.

In FIG. 1, the dotted line indicates the position of the inner non-slip portion 10 of the inner surface 1a, which is opposite to the outer surface 1b, on a plane, indicating that the inner non-slip portions 10 are completely spaced apart without overlapping or overlapping each other. will be.

In this configuration, as shown in the enlarged part of FIG. 1, the inner non-slip part 10 may more preferably form a spaced part 50 in which an outer circumferential surface thereof is spaced apart from the grating part 30.

Here, the separation part 50 forms a kind of buffer area.

The width of the separation unit 50 may be formed in various sizes according to the socks, and may be formed from 1mm to 8mm in size.

In addition, the position of the grating portion 30 is not formed only on the outer surface 1b of the illustrated foot apparel body 1, and in contrast to FIG. 1, the grating portion 30 is formed on the inner surface 1a. Embodiments will also be possible.

On the other hand, the inner non-slip portion 10 and the outer non-slip portion 20 will be arranged in a non-overlapping configuration with each other will be possible in various ways as shown in FIGS.

In addition, although not shown, the inner non-slip portion 10 and the outer non-slip portion 20 may be formed of several different patterns instead of one pattern.

In the figure, the portion indicated by the dotted line represents the inner non-slip portion 10, and the portion indicated by the solid line represents the outer non-slip portion 20.

In the figure, the inner non-slip portion 10 and the outer non-slip portion 20 are examples in which each unit unit exists in an independent form, and each independent unit does not overlap each other on a plane.

Among the various embodiments, the most preferred embodiment will be referred to as the embodiment of FIG.

In addition, the inner and outer non-slip portion may be the entire sole portion, and may be formed by non-slip treatment of part or all of the forefoot portion, the heel portion, and the heel portion that are partially applied to the sole. In other words, the wider the range of the non-slip portion, the more it can inhibit the intrinsic physical properties of the foot, such as stretch stone, it is also possible to adjust the range of the non-slip portion according to the type of the foot.

On the other hand, in the present invention, the inner non-slip portion 10 and the outer non-slip portion 20 may be made of a material having a variety of known non-slip functions, and can be installed in various ways such as integrally woven, adhesively applied to the adhesive. Can be.

The material may be composed of natural rubber, synthetic rubber, natural latex, thermoplastic rubber (TPR), thermoplastic elastomer (TPE), polyurethane, polyvinylchloride, synthetic and / or slip resistant finishes such as natural suede, and the like.

In addition, the attachment method may be formed by attachment using a hot press, attachment after drying by spraying, attachment by drying after pouring, painting, screen printing, and the like.

On the other hand, the material is most preferably made of a wet polyurethane sheet.

Preferred example may be made of a wet polyurethane sheet introduced in Patent Document 1 registered and filed by the applicant of the present invention.

As shown in FIG. 2, the pillar cell 11 having an inverted angular shape of the upper and lower straits is formed, and the whole or part of the pillar cell is formed on the opposite surface of the portion contacting the foot main body 1. It consists of a wet polyurethane sheet having a non-slip groove 12 communicated with the (11), the wet polyurethane sheet surface of the non-slip groove (12) by the hot melt adhesive 13 to the foot main body (1) This is an example attached to).

In FIG. 2, the enlarged portion shows the inner non-slip part 10, and the outer non-slip part 20 will also be apparent that the pillar cells and the non-slip grooves are symmetrically formed on the basis of the foot body 1.

Such a structure is described in Patent Document 1 as an example of the production method.

According to the example set forth in Patent Literature 1, the polyurethane was dissolved in dimethylformamide, coated with a comma coating or a knife coating on the carrier, and then coagulated in a coagulation bath containing a mixture of water and dimethylformamide. Substituted and removed, residual dimethylformamide was removed by hot air and dried to prepare a urethane sheet.The carrier was removed, and then the surface from which the carrier was removed was used as a non-slip surface. On the opposite side, a hot melt adhesive was applied to the sock body. The inner surface 1a and the outer surface 1b of (1) can be adhesively fixed to each other.

FIG. 3 shows a microscopic cross-sectional photograph of the configuration shown in FIG. 2, and FIG. 4 is a microscopic photograph showing a surface state.

The manufacturing method is a structure in which the pole cell 11 of the ottogi form is formed during the solidification process, and the surface from which the carrier such as the fabric or the polyester film is removed is non-slip surface, that is, the graping surface, so that sweat absorption is made smoothly. to be.

In this case, since the formation of the non-slip groove 12 may be uncertain depending on the material of the carrier, the auxiliary groove of reference numeral 12a may be additionally formed through a separate surface treatment such as peppering.

In another way, unlike Patent Document 1, the opposite side without carrier is formed with a skin during the solidification process, so that the hole in the surface is so small that the water absorption is slow, so that the surface membrane is removed with a pepper to a non-slip side with good sweat absorption. It can also be used.

As such, the surface of the wet urethane sheet can be used as a graphing surface by using the surface to be padded, or the fabric can be used as a graphing surface by using a fabric as a carrier, or a film can be removed by using a polyester film as a carrier. The face can be used as a graphing face.

Alternatively, when the wet urethane sheet is manufactured, the surface of the manufactured sheet after removing the surface skin of the manufactured sheet may be used as a graphing surface after impregnating and applying a nonwoven fabric to the polyurethane resin.

Such a non-slip material is preferably 1 mm or less in thickness in order to maintain the elasticity of the foot garments and to reduce foreign matters when wearing the foot garments.

On the other hand, in the above-described configuration, as shown in FIG. 1, the foot garment body 1 may be attached to the protective film 60 of the TPU material by a hot melt adhesive 61 to a portion covering the upper surface of the toe of the wearer. have.

When the protective film 60 is attached, the foot apparel body 1 may be good for sports socks, but most of all, it is useful when the foot apparel body 1 is made of a very thin material such as stockings, tights, and underlined clothing. .

This means that when women wear tights or tights and shoes with high heels, the feet become sore and the front of the shoe touches, and the big toe touches the shoe, especially the hard toe of the big toe and the inner lining of the shoe. And rub against each other to make holes in this area.

However, as described above, when the protective film 60 of the TPU material having excellent elongation through the hot melt adhesive 61 is attached, it is possible to prevent the hole.

At this time, the protective film 60 can be installed to prevent holes by applying heat and pressure to a thin TPU film of 50 microns thick heat melt pressure.

Referring to the action of the non-slip feet of the present invention configured as described above are as follows.

5 is a cross-sectional view conceptually illustrating a state in which a non-slip foot garment of the present invention is not worn by a wearer, and FIG. 6 is a cross-sectional view conceptually illustrating a state after wearing.

As shown in the figure, the inner non-slip portion 10 and the outer non-slip portion 20 are alternately arranged with each other, and a space of a margin exists like the spaced portion 50 therebetween.

Since the attached positions are staggered from each other, the non-slip material itself improves the transmission ability of the movement, but suppresses the transmission of excessive force as in Patent Document 3.

That is, when the frictional force and the compressive load are applied to the inner surface of the user's foot and the main body of the foot at the point of the inner non-slip portion 10 at the point, the bottom portion of the inner surface of the shoe is not located because the outer non-slip portion 20 is not located. Since it is possible to slip and to cushion a part of the friction at the point, but the outer non-slip portion 20 is located in the immediate vicinity of the lower portion so that the outer non-slip portion 20 around the role to reduce the friction again do.

This is not a method of intensively reducing friction at one point, but primarily reducing friction at the inner non-slip part 10 and reducing friction at the second non-slip part 20 at the displaced point around it. It is to play a role, it is possible to prevent skin wounds due to the intensive non-slip function provided to the wearer's feet.

In particular, when the space of the same space as the spaced portion 50 is formed, such a buffer effect can be further enhanced.

Since the spaced portion together with the non-overlapping staggered arrangement provides a buffer space, it is possible to smoothly absorb the sweat while preventing skin damage as compared with the configuration of Patent Document 3.

On the other hand, as can be seen from the changes in Fig. 5 to 6 when the wearer's load is applied in the worn state, the inner non-slip portion 10 and the outer non-slip portion 20 on the inner surface 1a and the outer surface 1b. As a result of staggering, the lower part of the foot garment body 1 comes into contact with the surface of the shoe 3 and the upper part comes into contact with the wearer's foot 2.

Since the load is applied to the user's foot (2), and underneath the shoe (3) is supported, the compressive force is received between the two, so that the body of the foot (1) made of a material having a soft and reliable Is modified as shown.

Therefore, in the case of the socks overlapping each other up and down as in Patent Document 3, the non-slip material is located at the same point, on the contrary, a thick portion and a thin portion are formed to provide the wearer with an uncomfortable feeling, while the configuration as shown in FIG. The overall flat surface provides a more comfortable fit.

In an enlarged view of the state of FIG. 6, an arrow shows a state of movement of sweat.

Referring to the absorption and discharge of sweat through this figure are as follows.

First, since the pillar cell 11 and the non-slip groove 12 are formed in the inner non-slip portion 10 as described above, the sweat discharged from the wearer's foot 2 is absorbed.

At this time, since the hot melt adhesive 13 is generally a material close to waterproof, the hot melt adhesive 13 delays the absorption of sweat, and if sweat continues to occur, the sweat moves through the sidewall surface of the inner non-slip part 10. do.

This part corresponds to the spaced-apart spaced part 50 between the inner non-slip part 10 and the outer non-slip part 20 in plan view, and this part corresponds to a wavy cross-sectional change of the foot body 1 as shown in the figure. As a result, an empty space is formed between the user's feet 2 so that a small amount of sweat temporarily stays.

However, when the foot body body (1) is made of a material having excellent sweat absorption, such as sports socks, the sweat is absorbed by the body body (1).

When continuous sweating occurs, the sweat is directed to the bottom of the shoe (3). At this time, in the area where the outer non-slip part (20) is attached to the outer surface (1b) of the main body of the foot (1) by the hot melt adhesive (23). Absorption of sweat is inhibited, and the sweat is eventually moved through the spaced part 50, and then absorbed into the column cell 21 inside the outer non-slip part 20 through the side wall surface of the outer non-slip part 20. Will be.

Such a configuration is that the inner non-slip portion 10 and the outer non-slip portion 20 will be sufficiently sweated, while the foot body 1 will be configured to smoothly drain the sweat.

This action has a difference in action from the sock disclosed in Patent Document 3.

Even if the structure of Patent Literature 3 is made of the same material as the non-slip portion of the present invention, Patent Literature 3 has a structure in which the non-slip portions overlap each other up and down, so that the graphing member on the inner surface absorbs sweat, and then the graphing on the outer surface. Since the member is located directly underneath it, it is possible to enter and exit through the sidewall of the graping member on the outer surface only after the sock is sufficiently wet, so that drainage is not desired and the sock is wet and the surface of the user's foot that comes in direct contact with the sock is sweaty. It becomes a vane state.

That is, the sweat absorption to the graping member of the outer surface is not smooth.

Non-slip foot apparel of the present invention can be applied to a variety of clothing that directly wraps and protects the wearer's feet, such as sports, mountaineering socks, tights, over socks, life socks.
