Abstract

The invention relates to five toe shoes for protecting feet while working or taking part in leisure activities on land or water and in the mountains. In particular, a five toe shoe comprises: an upper which is made out of a moisture-permeable fiber material and has a toe area to encase each toe separately according to the shape; an insole which is made out of a porous material; a midsole which is placed underneath the insole and has a metal mesh to allow water in the shoe to exit therethrough; and an outsole which has a drain formed in coincidence with the metal mesh of the midsole and a toe area for each toe separately according to the shape, being connected to the toe area of the upper in a one-to-one correspondence therebetween. Thus, five toe shoes may contribute greatly to foot health of wearers by improving breathability as water from the inside of the shoes drains naturally by gravity via the insole, midsole and outsole and evaporates quickly through the upper at the same time, and offer more convenience in activities with the toe area encasing each toe separately according to the shape.

Description

Toe shoes

The present invention relates to a toe shoe worn when performing work or leisure activities in the land, water and mountain, and more specifically, the water inside the shoe is quickly drained through the insole, midsole and sole, and effectively through the upper It relates to a toe shoe that evaporates to improve breathability and thus contribute to the health of the wearer's foot and provide the convenience of activity.

When performing work or leisure activities on land, water, and mountains, walking barefoot is not only uncomfortable to walk, but also frequently causes foot injuries. However, when water activity is worn by wearing general shoes to prevent foot injury, walking is very inconvenient, and water inside the shoe is not drained and evaporated quickly, which adversely affects the health of the wearer's foot.

In order to solve the above problems, research and development on the toe shoes worn on the foot when active in the water is actively progressing. For example, Korean Laid-Open Patent Publication No. 2000-12697 (name of the invention: sea bathing shoes) discloses a sea bathing shoe including a bottom of a polyurethane material and a zipper of a connection portion. These bathing shoes can protect your feet relatively safely, reduce discomfort on the water floor and provide buoyancy, but the toes are not divided into individual toe shapes, which means that your toes are often injured when you are active in the water. There is a problem in that the water inside the shoe is not drained and evaporated quickly, so that a blister or athlete's foot occurs on the wearer's foot or the foot becomes cold, which adversely affects the health of the foot.

In addition, Korean Utility Model Publication No. 20-0433258 (designated toe shoes) discloses a toe shoe in which five toe inserts are formed at the tip of the shoe. These toe shoes are divided into individual toe inserts, each toe insert is inserted into each toe to prevent injury to the toe when active in the water, and can provide convenience for walking activities, but drain the water inside the shoe Since there is a lack of means for evaporation or evaporation, there is a problem that the water inside the shoe is not drained and evaporated quickly, which adversely affects the health of the wearer's foot.

In addition to the above water-based footwear, the research and development of shoes that can protect the health of the wearer's foot and improve the wearing comfort by quickly draining the water inside the shoes are actively being conducted. For example, Korean Registered Utility Model Publication No. 20-042202 (the name of Goan: Water leisure shoes) discloses water leisure shoes in which a plurality of through holes are formed on the circumferential surface. The upper of these water leisure shoes is configured to rapidly evaporate water, but since the sole lacks a means of draining or evaporating water, the water inside the shoe does not drain and evaporate quickly, which may affect the health of the wearer's feet. There is a problem that adversely affects.

In addition, Korean Patent Laid-Open Publication No. 1990-0002732 (Invention: Ship Shoes) is a drainage part in which water inside the shoe is collected at the front part and the rear part of the midsole, and a drainage path formed at the side part and the rear part of the shoe at the drain part. Disclosed is a shoe for a ship comprising a sole formed. These marine shoes can theoretically drain the water inside the shoe through a drain, but the exit of the drain does not form the bottom of the shoe sole, which is affected by gravity, but rather the sides and rear of the shoe sole that are not affected by gravity. Since it is formed as, in reality, the water inside the shoe is not properly drained, and there is a problem that the water inside the shoe is not quickly evaporated through the upper.

In addition, the Korean Utility Model Publication No. 1992-1878 (the name of the draft: shoes having a drainage function at the bottom) is provided with drainage holes at the upper, middle, and bottom portions, respectively, to drain the water inside the shoe. A shoe having a drainage function at the bottom thereof is disclosed. A shoe having a drainage function at such a bottom may drain water from the inside of the shoe to the ground through a drain hole in the upper, middle, and lower parts of the shoe, but lacks a means for blocking foreign matter from entering the shoe into the shoe. Because of this, foreign matter on the ground is likely to flow into the shoe through the upper, middle and bottom drain holes, and there is a problem that the water inside the shoe does not evaporate quickly through the upper.

In addition, Korean Laid-Open Patent Publication No. 2005-009873 (name of the invention: the sole of the shoe provided with a vent on the bottom surface and the outer periphery) is provided with a double midsole and a plurality of vents and a plurality of vents are formed in the upper and lower separation The shoe sole is provided with a vent hole in the bottom surface and the outer periphery and the outer periphery is inserted between the moisture-proof waterproof plate therebetween. These shoe soles can be thought of as draining the water inside the shoe through the vents in the midsole and the vents in the soles, but in reality the moisture-permeable waterproof soles of the soles are configured to pass moisture or air and to prevent the inflow of moisture. There is a problem that the water inside the shoe is not quickly drained through the moisture-proof plate of the sole.

In addition, all the prior art shoes described above are not distinguished between the endothelial and the outer skin, some prior art shoes are simply configured using only porous fibers that can easily permeate moisture, such porous fibers only The upper constructed using is not very durable and greatly shortens the life of the shoe, and it is difficult to put it to practical use because the elasticity and flexibility of the porous fiber, which is the upper material, is insufficient, and the fit of the toe shoe wearer is reduced. I have it.

Accordingly, it is an object of the present invention to include means for quickly draining and evaporating water in a shoe such that the water in the shoe is naturally drained by gravity through the insole, midsole and sole, and quickly evaporated through the upper for breathability It is improved, and the toe part is divided into individual toe shapes to provide toe shoes that provide the convenience of activities in the land, water and mountain.

In order to solve the above problems, the present invention is made of a moisture-permeable fiber material and the toe portion is formed to be divided by toe shape; Insole formed from a porous material; A midsole formed at a lower portion of the insole and formed with a metal mesh portion through which water in the shoe is drained; A sole which is formed to correspond to the metal mesh part of the midsole, and the toes are divided according to the toe shape so as to correspond to the upper toe shape, respectively; And a vent made of a hydrophobic fiber knitted fabric at a portion between the toe section and the toe section formed by connecting the toe portion of the upper and the toe portion of the outsole.

Toe shoes according to the present invention is naturally drained through the insole, midsole and sole by gravity by gravity, and at the same time rapidly evaporated through the upper to improve ventilation, greatly contribute to the health of the wearer's foot, It is categorized by type to provide the convenience of activities by increasing the activity and landing feeling of walking during water activities, and can be used for various purposes in land and mountain as well as water activities.

In addition, in the toe shoe of the present invention, the metal mesh portion is formed in the hole of the sole in which water inside the shoe is naturally drained by gravity, thereby preventing foreign substances on the ground from flowing into the hole of the sole.

1 to 5, in the toe shoe of the present invention, the toe portion of the shoe is divided into individual toe sections, and the toes are individually inserted into each of the toe sections when the shoes are worn.

To this end, the toe shoe according to an embodiment of the present invention is made of a moisture-permeable fiber material and includes an upper (1a) formed to be divided by the toe portion.

In other words, the toe shoe is composed of the upper (1a) and the sole, the sole is composed of the insole (2), midsole (3) and the sole (4), the upper (1a) covering the wearer's foot as a whole The toe part, that is, the tip part, is divided into the same shape as the five toes, and the divided toe shape is individually connected to the branched toe shape of the sole 4, so that the toe part of the toe shoe is an individual toe. It is divided into compartments.

As described above, the upper (1a), which is divided by the toe shape by cutting the toe part, is composed of a three-layer structure of the outer skin, the middle skin, and the endothelial body, providing elasticity and flexibility to the toe shoes while evaporating the water inside the shoes quickly In order to make the outer shell is made of a spandex fabric material having excellent elasticity, the intermediate skin is a rubber material, the upper 1a is a knitted fabric having a three-layer structure consisting of the spandex fabric material. Toe shoes, in which upper 1a, which is a three-layer knit fabric of spandex fabric, rubber and spandex fabric, are formed, have greatly increased elasticity and flexibility, and the wearer feels greatly improved.

As described above, the one or more mesh vents 8 made of mesh fibers having a very excellent function of permeating air and moisture in one part of the upper 1a may provide additional breathability to the upper 1a. It is preferable in that it can.

Particularly, a part of the upper layer 1a having a three-layer structure is cut out, and one or more mesh vents 8 which cover the mesh fibers in the cut holes to easily transmit moisture through the upper portion 1a are formed. Air is smoothly communicated in and out of the toe shoe through the mesh vent 8 formed in at least one, and the moisture inside the shoe is easily released.

In addition, the toe shoe according to an embodiment of the present invention includes an insole formed of a porous material.

The outsole of the toe shoe consists of an insole (2), a midsole (3) and an outsole (4), which are formed on the top of the outsole and face the wearer's sole so that the insole (2) easily penetrates the water inside the shoe. Made of porous material.

Specifically, the insole 2 is made of a material selected from the group consisting of porous fabrics, synthetic resins, and synthetic rubber. When the insole 2 is made of porous fabric, the insole 2 permeates water easily. When the insole 2 is made of synthetic resin material or synthetic rubber material, it is preferable that a plurality of vent holes 9 are formed in the insole 2 to promote the function of draining the water inside the shoe.

By the insole 2 as described above, the water inside the shoe is easily drained to the midsole 3 and the sole 4, thereby greatly improving the wearing feeling of the toe shoe wearer and greatly contributing to the health of the foot.

In addition, the toe shoe according to an embodiment of the present invention includes a midsole formed in the lower portion of the insole and the metal mesh is formed to drain the water inside the shoe.

In the sole of a toe shoe, the midsole 3 disposed between the insole 2 and the sole 4 is formed with at least one metal mesh portion 6 to drain the water inside the shoe.

Specifically, a portion of the midsole 3 of natural rubber or synthetic rubber is perforated to form at least one hole, and foreign matter on the ground may be introduced into the shoe through the hole. Therefore, in the present invention, in order to prevent foreign substances on the ground from flowing into the shoe through the hole of the midsole 3, a mesh made of a metal material is covered in the hole so that the metal mesh part 6 communicating air is configured. The water penetrating the insole 2 passes through the metal mesh portion 6 of the midsole 3 and is drained out of the shoe. In addition, as described above, the metal mesh part 6 is formed in the midsole 3 to prevent water from being drained from the inside of the shoe and foreign matter from the ground flowing into the shoe.

In addition, the toe shoe according to an embodiment of the present invention is formed with a drain hole corresponding to the metal mesh portion of the midsole, and the toe is divided by toe shape includes a sole which is formed to correspond to each of the upper toe shape. .

In the sole of the toe shoe, the sole 4 disposed at the lower portion of the midsole 3 to support the midsole 3 is divided by the toe shape like the upper 1a, and the divided soles Since the toe shape of (4) is individually connected to the toe shape of the upper 1a, the toe portion of the toe shoe is divided into individual toe sections.

By the way, in the shoe as described above, the portion between the toe section and the toe section formed by connecting the toe portion of the upper 1a and the sole 4 is most likely to be wet. Accordingly, in order to easily evaporate the water filled between the toe section and the toe section of the toe shoes, the vent 5 made of hydrophobic knitted fabric is formed at the part between the toe section and the toe section. It is preferable in terms of improving the air permeability. Ventilation part 5, which provides breathability to the toe shoe, is not a mixed fiber of polyester and cotton, which is a material generally used in shoes but has a high affinity with moisture and lacks drainage, but excludes moisture. A hydrophobic knitted fabric knitted with hydrophobic fibers having a property of being used as a material, and the water filled between the toe section of the toe section and the toe section of the toe shoe is easily evaporated through the ventilation section 5 of the hydrophobic knit fabric. Will be.

The vent of the toe shoe can be constructed using a knitted fabric made of general synthetic fibers having excellent drainage, but among the synthetic fibers, polyester fibers having excellent drainage and hydrolysis resistance, nylon fibers having excellent flexibility, and polyester and nylon It is preferable to use a knitted fabric knitted with hydrophobic fibers selected from the group consisting of mixed fibers.

At least one drain port 7 for draining the water passing through the metal mesh part 6 of the midsole 3 to the outside of the shoe is formed in the sole 4 of the shape and structure as described above.

Specifically, since the sole 4 is perforated in the same position and shape as the metal mesh 6 of the midsole 3 to form the drain hole 7 of the sole 4, the water in the shoe is caused by gravity It is naturally drained to the outside of the shoe through the inlet 2, the metal mesh portion 6 of the midsole 3 through the drain 7 of the sole 4.

In addition, referring to FIG. 6, in the second embodiment of the present invention, an upper 1b using a double raschel knitted fabric having a cushioning material formed on the inner skin and a porous fiber formed on the outer material is used. And the insole 2, which is embraced by the upper 1b and is formed of a porous material, a midsole 3 having a metal mesh part 6 through which water in the shoe is drained, and a metal of the midsole 3. Drain hole 7 is formed to match the mesh portion 6 and the toe portion is divided by toe shape provided toe shoes including an outsole (4) formed to correspond to each of the toe shape of the upper (1b) do.

Conventional shoes are not distinguished between the inner and outer shells, and are simply configured using only porous fibers that can easily permeate moisture, and the uppers formed by using such porous fibers as materials have a very poor durability and thus have a long service life. Not only is it greatly shortened, the elasticity and flexibility of the porous fiber of the upper lacks the wear of the toe shoe wearer has a problem that it is difficult to put to practical use.

In order to solve the above problems, a double raschel structure of a double structure of a porous fiber, a cushioning material formed on one surface of the porous fiber to provide moisture permeability to the upper (1b) by excellent air communication function The upper 1b is comprised using the moisture permeable fiber material which is a knitted fabric.

As described above, the toe shoe having the upper 1b, which is a double-lasel knitted fabric made of a double structure of porous fibers and a cushioning material, is easily evaporated, and the elasticity and flexibility of the upper 1b are greatly increased. Thus, the feeling of wearing felt by the operator of the toe shoe is greatly improved.

The upper (1b) of the double-lassel structure knitted fabric material, the insole (2) formed of a porous material, the midsole (3) formed with a metal mesh portion 6 to drain the water inside the shoe, and the midsole (3) Toe shoes consisting of a sole (4) is formed to correspond to the toe shape of the upper (1b) is formed by the drain hole (7) to match the metal mesh portion (6) of the) This is made up.

As described above in detail with respect to the configuration of the toe shoe of the present invention, only the toe shoes including all of the above-described components, the water inside the shoe is natural and quick through the insole, midsole and sole by gravity At the same time, it is effectively evaporated through the upper to improve ventilation, which can greatly contribute to the health of the wearer's foot, and can be achieved by the purpose of the present invention that can be divided by toe shape and provide convenience of activities. It is obvious that such a purpose of the present invention cannot be achieved when the shoe does not include all of the above components.
