Description

Shoes{SHOES}

The present invention relates to a shoe, and more particularly, to a shoe with improved breathability that effectively releases sweat or moisture generated in the shoe.

Shoes, which have been used to protect feet while walking on a bipedal foot by humans, have been developed with the development of science and technology, and nowadays, various types of shoes are suitable for various activities such as home, walking, mountain, body correction, and special exercise. Different types of shoes are being made. These shoes not only protect the feet of the person wearing them, but are made to pursue the convenience of activities performed while wearing the shoes.

At this time, the foot inserted into the shoe forms a distribution of about 500,000 sweat glands, which occupies about 20% of a person's total sweat holes, and is the area that secretes the most sweat except for the forehead.

Accordingly, in the case of an activity while wearing shoes, sweat is secreted up to about 12 times more than usual.

Therefore, it is important to protect the wearer's feet and pursue the convenience of wearing them, but if breathability is not secured, the shoes become sweaty due to the heat generated from the feet and foot odors are generated. In the end, it can be said that one of the important elements of a shoe is to solve the problem caused by it by effectively discharging heat or sweat generated from the foot.

In order to solve this problem, conventionally, a technology has been proposed in which air can be discharged to the outside through an insole by forming an air hole through which air can be discharged on the side or bottom surface of the outer shell exposed to the surface. Model No. 20-0192510 (air discharge shoes), Patent Publication No. 10-2000-0035118 (Shoe Insole with Air Hose), and Patent Publication No. 10-0470751 (Shoes with external air circulation). For example. However, since this conventional technology is ventilated through the bottom of the shoe or the side of the shoe, it is inevitable that water enters the shoe when water is accumulated on the ground, and it is a very fatal weakness in shoes that require a waterproof function such as boots. Can act as

Accordingly, the present inventors have proposed a dual structure shoe in which through holes are formed in the inner and outer skins so that air can be discharged through the instep and ankle portions. These include Registration Patent Publication No. 10-1737910 (breathable shoes having a double structure in the upper part), Registration Patent Publication No. 10-1711881 (sulfo breathable shoes), and Unexamined Patent Publication No. 10-2017-0122645 (double in the upper part. Breathable shoes having a structural part), and in Patent Publication No. 10-1767884 (Method of Manufacturing Breathable Boots), a method of manufacturing such shoes has been disclosed.

Registered Utility Model No. 20-0192510 (2000.08.16) Unexamined Patent Publication No. 10-2000-0035118 (20001.10.05) Registered Patent Publication No. 10-0470751 (2005.03.08) Registered Patent Publication No. 10-1737910 (2017.05.19) Registered Patent Publication No. 10-1711881 (2017.03.13) Unexamined Patent Publication No. 10-2017-0122645 (2017.11.06) Registered Patent Publication No. 10-1767884 (2017.08.23)

In addition, terms used in the present specification are terms used to appropriately express embodiments of the present invention, and these may vary according to related people or customs in the field. Accordingly, definitions of these terms should be made based on the contents throughout the present specification.

The terminology used herein is for reference only to specific embodiments and is not intended to limit the invention. Singular forms as used herein also include plural forms unless the phrases clearly indicate the opposite. As used in the specification, the meaning of'comprising' specifies a specific characteristic, region, integer, step, action, element and/or component, and other specific characteristic, region, integer, step, action, element, component and/or group It does not exclude the existence or addition of

Hereinafter, a shoe according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, a shoe according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5.

The shoe 1 according to an embodiment of the present invention includes a body 10, an air passage part 20 protruding in the front outward direction of the body 10, and a plurality of feet attached to the air passage part 20. It has a support part (30).

The body 10 is a part that is worn on the foot of the user 200 by inserting the foot of the user 200, and the bottom portion 110, the instep portion 120 connected to the bottom portion 110, and the instep portion 120 ) And has an ankle part 130 connected to it.

The bottom portion 110 is a portion where the sole of the user 200 is located, and contacts the sole of the user when wearing shoes.

The instep portion 120 is a portion surrounding the instep of the user 200, and the foot of the user 200 is inserted into the space surrounded by the bottom portion 110 and the instep portion 120 to wear shoes.

The ankle part 130 is a part that is seamlessly connected to the end of the instep part 120 and protrudes toward the body of the user 200, and according to the protruding length of the ankle part 130, not only the user's ankle but also a part of the leg is It is worn under shoes (1).

At this time, the ankle part 130 may be omitted or the protruding length of the ankle part 130 may be adjusted, and various types of shoes are manufactured by omitting the ankle part 130 or adjusting the protruding length.

The air passage portion 20 is a convex portion protruding outwardly with a predetermined width W20 at the front center portion of the instep portion 120 and the ankle portion 130.

The air passage part 20 is located in a straight line along the ankle part 130 from the instep part 120 of the body 10.

At this time, the air passage part 20 is located at the connection part between the bottom part 110 and the instep part 120 and the upper couple of the fore nose part 121 of the shoe 1 where the toe is mainly located, that is, the start part of the instep It extends in a straight line along the same direction from the portion (ie, the instep start portion) 122 corresponding to the instep portion 120 to the end portion of the ankle portion 130. In this example, the front nose portion 121 forms a part of the instep portion 120.

At this time, the width W20 of the air passage part 20 may be the same regardless of the height, and the discomfort and aesthetics of the user 200 wearing the shoe 1 are not impaired. It is good if it is large enough to efficiently discharge heat or sweat. For example, the width W20 of the air passage part 20 may be 0.5 cm to 2 cm.

The protruding height H20 of the air passage part 20 may be different from each other in the width direction at the same height. That is, since the planar shape of the inner surface and the outer surface of the air passage part 20 is made of a curved surface rather than an angular shape, as shown in FIG. 2, the air passage part 20 at the same height has a protruding height ( H20) may be larger than the protruding height H20 of the edge portion.

In this example, the protrusion height H20 extends from the instep start portion 122 toward the ankle portion 130 and extends at the same distance as the inner surface of the adjacent air passage portion 20 at a virtual line L1 It is the shortest distance to the inner surface of the air passage part 20, and the width W20 of the air passage part 20 is between both sides of the inner surface of the air passage part 20 facing each other in the width direction. May be the shortest distance.

Therefore, as shown in Figure 3, the air passage portion 20 has a predetermined width (W20) in the front center portion of the body 10, protrudes outward, and extends toward the body of the user 200 ( It extends to the end of the body 10 along the extension direction of 10).

The plurality of foot support portions 30 are portions for safely and conveniently supporting the feet and legs of the user 20 inserted into the shoes 1, respectively, between both sides of the inner surface of the air passage portion 20 It is located and is arranged to be spaced apart along the extension direction of the air passage portion 20 (ie, the direction opposite to the width direction, from the instep portion 120 to the ankle portion 130).

The foot support part 30 may have the same shape and size such as a bar shape or a band shape, but at least one of the shape and size of the foot support part 30 may be different depending on the location where it is located. have. When at least one of the shape and size is different depending on the location, the shape and size of the foot support 30 may be determined according to the shape of the user's body in contact with the foot support 30.

Therefore, one side of the foot support part 30 is connected to one side of the inner surface of the air passage part 20, and the other side of the foot support part 30 is connected to the other side of the inner surface of the air passage part 20 There, each foot support portion 30 is positioned side by side in the width direction of the air passage portion 20.

At this time, since the adjacent two foot support portions 30 are spaced apart at the same interval, the plurality of foot support portions 30 may be spaced apart at regular intervals along the extending direction of the air passage portion 20.

However, in an alternative example, the separation distance between adjacent two foot supports 30 may be different. In this case, as shown in FIG. 1, instead of being uniformly positioned along the extension direction of the air passage portion 20, the plurality of foot support portions 30 may be positioned only at a predetermined specific position.

For example, the plurality of foot support portions 30 are spaced apart at predetermined intervals in the portion of the air passage portion 20 corresponding to the user's instep portion and the portion of the air passage portion 20 corresponding to the user's leg portion. The foot support part 30 may not be located in the part of the air passage part 20 corresponding to the ankle part where the foot bending phenomenon mainly occurs. In this case, the separation distance from the portion where the foot support part 30 is located may be the same.

In this way, when the plurality of foot support portions 30 are located only at a predetermined specific position of the air passage portion 20, the plurality of foot support portions 30 are already in order to minimize the discomfort of the foot located in the shoe (1). As described above, the foot support part 30 may not be located in a part where the bending operation of the shoe 1 is mainly performed in the air passage part 20, that is, a part corresponding to the ankle part.

In this way, when a plurality of foot support parts 30 are located in a specific position, the activity of the shoe 1 is improved, and the foot support part 30 and the skin contact with the skin when folding the ankle of the shoe 1 Skin damage caused by is prevented.

In this way, as the plurality of foot support portions 30 are positioned along the extension direction of the air passage portion 20, the open portion of the air passage portion 20 in which each foot support portion 30 is located is the corresponding foot support portion ( 30) and is separated from the space surrounded by the instep portion 120 and the ankle portion 130.

Accordingly, the lower and side portions are surrounded by the bottom portion 110, the instep portion 120, the ankle portion 130 and the air passage portion 20 of the body 10, and the upper portion of the shoe 1 is opened. The space is a space (S10) surrounded by a floor part 110, an instep part 120, an ankle part 130, and a plurality of foot support parts 30, an air passage part 20, and a plurality of foot support parts 30 It is divided into a space (S10) surrounded by.

At this time, the space (S10) is a foot insertion space into which the user's foot is inserted, and the space (S20) becomes an air passage through which air flows between the inside and the outside of the shoe (1), so that the air passage part 20 and the The air passage (S20) is formed between the foot support (30).

At this time, the air passage (S20) is separated from the foot insertion space (S10) of the body (10) in which the user's foot is inserted in the portion where the foot support portion (30) is positioned, but the foot support portion (30) is not positioned. Since the insertion space (S10) and the foot insertion space (S10) communicates with the outside through the air passage (S20).

Therefore, due to the formation of the air passage 20, air flows between the inside and the outside of the shoe 1 so that heat or sweat generated in the shoe 1 is quickly discharged to the outside through the air passage 20 It makes the environment inside the shoes (1) comfortable.

In addition, as a plurality of foot support portions 30 each positioned across the width direction of the air passage portion 20 protruding outward from the body 10 of the shoe 1 are positioned, as shown in FIG. , The foot insertion space S10 in which the user's foot is substantially inserted and positioned is, as already described, a space surrounded by the body 10 and a plurality of foot support portions 30.

Therefore, when the foot is inserted into the foot insertion space (S10), the instep and shin of the user 200 located in the front portion of the shoe 1 are limited by the plurality of foot support portions 30, so that the body 10 The problem that the foot insertion space S10 increases due to the air passage portion 20 protruding to the outer portion of the is prevented.

For this reason, despite the formation of the air passage portion 20, the foot insertion space S10 by the air passage portion 20 does not increase, so that the foot insertion space ( Since the size of S10) is determined, the problem of deteriorating the fit of the shoes 1 due to the air passage 20 does not occur.

In the shoe 1 of this example, the body 10, the air passage part 20, and the foot support part 30 may all be made of the same material, and may be made of a material such as natural rubber, synthetic rubber, or synthetic resin.

For example, polyethylene (PE), which is non-toxic, has excellent chemical resistance, and has excellent insulation, polyvinyl chloride (PVC), which has excellent light resistance, chemical resistance and electrical insulation, and is non-adhesive, non-oil, and thermoplastic with high insulation properties. Rubber, TPR (Thermoplastic Rubber), which is resistant to cold resistance and acids or alkalis, SBS (Styrene butadiene styrene), which has excellent heat resistance and flexibility at low temperatures, SEBS (Styrene ethylene butylene styrene), or EPDM (Ethylene propylene diene M-class). Can be done.

In addition, the trunk (10), air passage (20) and foot support (30) are SEPS (styrene ethylene propylene styrene), SEEBS, SEEPS (styrene-ethylene-ethylene/propylene-styrene), EVA (ethylene vinyl acetate), It may be made of rubber or foamed resin such as TPU (thermoplastic polyurethane), PU (polyurethane), PS (polystyrene), PP (polypropylene), TPO, TPV (thermoplastic cured rubber).

In an alternative example, the bottom portion 120 of the trunk 10 may be made of a material different from the other portions 120 and 130 of the trunk 10, and in this case, the bottom portion 120 and the instep portion 120 ) And the ankle part 130 may be made of a material such as natural rubber, synthetic rubber, or synthetic resin.

In another example, the body 10 and the air passage part 20 are made of the same material as each other, but a part of the foot support 30 may be made of a different material from the body 10 and the air passage part 20 . In this case, the body 10 and the air passage part 20 are made of a material such as natural rubber, synthetic rubber, or synthetic resin, but the portion of the foot support 30 adjacent to the user's body and in contact with the skin It is made in the form of an added fiber, etc., and the other part of the foot support 30 may be made of the same material as the body 10.

In this example, the number of foot support portions 30 is plural, but otherwise, it may be one.

Next, with reference to FIGS. 6 to 16, the shoes 1a-1f according to another embodiment of the present invention will be described.

In this embodiment, compared to the shoe 1 shown in FIGS. 1 to 5, the same reference numerals as the shoe 1 shown in FIGS. 1 to 5 for components having the same structure and performing the same function And a detailed description thereof will be omitted.

First, a shoe 1a for one example according to another embodiment of the present invention will be described with reference to FIGS. 6 to 7B.

Compared with the shoe 1 shown in FIGS. 1 to 5, the shoe 1a according to another embodiment of the present invention further includes an insole 50 positioned at the bottom 110 of the body 10. .

Therefore, as shown in Figure 6, the other shoe (1a) in this example is a body 10 having a bottom portion 110, an instep portion 120 and an ankle portion 130, the front center of the body 10 The air passage portion 20 positioned to protrude outward from the portion, a plurality of foot support portions 30 positioned along the extension direction of the air passage portion 20, and the insole 50 positioned in contact with the bottom portion 110 Equipped.

This insole 50 has substantially the same shape as the shape of the bottom part 110 and is located in the bottom part 110 surrounding the foot insertion space S10 of the shoe 1a, so the bottom part 110 Has a size smaller than the size of

In this example, the insole 50 may include a moisture discharge unit 51 as shown in FIGS. 7A and 7B.

At this time, the moisture discharging part 51 may be in the form of a hole that completely penetrates the insole 50 in the thickness direction of the insole 50 or a groove formed on the surface of the insole 50 without completely penetrating the insole 50. .

The shape of the water discharging part 51 formed on the insole 50 may be, for example, a linear shape as shown in FIG. 7A or a circular shape as shown in FIG. 7B, but is not limited thereto. They may have various shapes such as the same polygon, ellipse shape, and wave shape, and all may have the same shape and size or different sizes and shapes.

In addition, since the insole 50 of the present example is detachably located on the bottom portion 110, it may be located in the foot insertion space S10 or removed outside the foot insertion space S10 according to the needs of the user. Therefore, the user can separate the insole 50 from the shoe 1a and wash it separately.

The insole 50 may be made of a material having elasticity such as natural rubber, synthetic rubber, or synthetic resin, and fibers may be additionally attached to the surface in contact with the sole of the user.

When these insoles 50 are additionally provided on the shoes 1a, the magnitude of the impact applied to the feet of the user 200 wearing the shoes 1a is greatly reduced and the protective function of the feet is further strengthened, so that the user 200 )'S satisfaction is improved.

Moreover, sweat discharged from the sole of the foot by the water discharge part 51 formed in the insole 50 is discharged toward the bottom part 110 through the water discharge part 51 or is collected in a groove formed in the water discharge part 51 . Accordingly, the fit of the shoe 1a is improved and the foot is protected from sweat.

In addition, when the moisture discharge part 51 is formed in a hole shape, the sweat discharged to the bottom part 110 is vaporized and quickly discharged to the outside through the air passage part 20, and heat generated from the user's feet is also It is quickly discharged to the outside through the moisture discharge part 51 and the air passage part 20.

In this way, when the shoe 1a additionally includes the insole 50, the corresponding inner surface (ie, the upper surface) of the bottom portion 110 in contact with the insole 50 in the shoe 1a shown in FIG. ) Has a flat surface.

However, in the shoe 1b according to another example according to the present embodiment shown in FIGS. 8 and 9, the inner surface of the bottom portion 110b of the body 10b is not a flat surface but a concave-convex surface (凹凸面). Except for this point, the shoe 1b shown in FIGS. 8 and 9 has the same structure as the shoe 1a shown in FIG. 6. The moisture discharge part 51 formed in the insole 50 of this example has a hole shape penetrating the insole 50 in the thickness direction.

In addition, when the shoes 1b shown in FIGS. 8 and 9 are compared with each other, the shapes of the irregularities formed on the inner surface of the bottom portion 110b of the shoe 1b are different from each other.

That is, in the case of FIG. 8, the concave portion 111 and the convex portion 112 formed on the inner surface of the bottom portion 110b have a curved surface such as a semicircle, whereas in the case of FIG. 9, the bottom portion ( The recessed portion 111 and the convex portion 112 formed on the inner surface of 110b) have an angled surface such as a square.

In this case, an example of the uneven surface formed on the inner surface of the bottom portion 110b of the shoe 1b of FIG. 9 is formed in a grid shape as shown in FIG. 10A to form a rectangular concave portion 111 or a honeycomb shape as shown in FIG. 10B. Consisting of a hexagonal recess 111 may be formed.

However, the uneven shape of the bottom portion 110b shown in FIGS. 8 and 9 is an example, and may have various shapes of uneven shape.

At this time, the concave portion 111 formed on the bottom portion 110b is formed at a position facing the moisture discharge portion 51.

In this way, since the inner surface of the bottom portion 110b in contact with the insole 50 is made of an uneven surface having a concave portion 111 and a convex portion 112, the insole 50 is a convex portion 112 of the bottom portion 110b ), but not in contact with the concave portion 111, so that an empty space exists between the bottom portion 110b and the insole 50, that is, between the moisture discharge portion 51 and the concave portion 111.

In general, the bottom portion of the shoe in contact with the floor is in close contact with the toe portion, the metatarsal bone, and the heel portion along the foot sole of the user 200, and the arch portion between the metatarsal bone and the heel does not contact the floor. You will have a structure.

In addition, the toe, metatarsal, and heel portions that are in contact with the floor with a shoe interposed therebetween do not come into contact with the floor at the same time, but contact the floor in turn according to the walking type or exercise process of the user 200.

Therefore, since the bottom portion 110b of the shoe 1b partially contacts and non-contacts the bottom, moisture such as sweat is transferred to the concave portion 111 of the bottom portion 110 through the moisture discharge portion 51. The accumulated moisture is vaporized over time, moves along the empty space between the insole 50 and the floor 110b, which do not contact the floor, and is discharged to the outside through the air passage S20.

Accordingly, by the bottom portion 110b that is the uneven surface, the moisture that has passed through the water discharge portion 51 of the insole 50 is efficiently collected in the recessed portion 111 of the uneven surface, and the insole 50 and the bottom portion Since water evaporation is efficiently performed through the space formed between (110b), the solder discharge effect is further improved.

In addition, the sweat discharged from the insole 50 toward the bottom portion 110b is located in the empty space between the moisture discharge portion 51 and the recess portion 111, so that the sweat discharged toward the bottom portion 110b is again in the insole 50 It is prevented from entering the side.

In addition, as already described, the user 200 is safe without damage to the insole such as tearing because there is a space between the insole 50 and the bottom portion 110b that is not compressed by the flat surface of the bottom portion 110b. And the insole 50 can be easily removed from the shoe 1b, so that the water surface of the insole 50 is extended.

The shoe 1c of another example according to this embodiment shown in FIG. 11 is different from FIGS. 8 and 9, and the inner surface of the bottom portion 110 of the body 10 in contact with the insole 50c is shown in FIG. Likewise, while having a flat surface, a plurality of floor protrusions 52 are attached to a corresponding surface (ie, a lower surface) of the insole 50c in contact with the bottom portion 110. Therefore, due to the plurality of bottom protrusions 52, the lower surface of the insole 50c has an uneven surface.

At this time, the bottom protrusion 52 is located between the adjacent moisture discharge portions 51 formed in the form of holes. The size, location, and shape of the bottom protrusion 52 may be determined according to the size, location, and shape of the moisture discharge unit 51.

As such, the shoe 1c of FIG. 11 has the same structure as the shoe 1a of FIG. 6 except that a plurality of bottom protrusions 52 are attached to the lower surface of the insole 50c.

By such a plurality of bottom protrusions 52, the inner surface of the bottom portion 110 is mostly in contact with the bottom protrusion 52 of the corresponding insole 50c, so between the insole 50c and the bottom portion 110 (ie An empty space is formed between the moisture discharge part 51 and the inner side of the bottom part 110 corresponding thereto.
