Description

Prefabricated shoes {ASSEMBLY SHOES}

The present invention relates to a shoe, and more specifically, consists of a dual structure of a detachable inner shoe and an outer shoe, and improves breathability to effectively release sweat or moisture generated in the inner shoe. It relates to a structured prefab shoe.

Footwear, which has been used to protect feet while walking bipedally, has been developed as new materials have been developed with the development of science and technology, and today it is suitable for various activities such as household, walking, mountain, body correction, special exercise, etc. Eggplant shoes are being made. These shoes are made not only to protect the feet of the person wearing them, but also to pursue the convenience of activities made while wearing shoes.

At this time, the foot inserted into the shoe forms a distribution of about 500,000 glands, which occupy about 20% of the total sweat hole of a person, and is the most secreted part of sweat except forehead. Accordingly, if you are active while wearing shoes, you will release up to 12 times more sweat than usual. Therefore, it is also important to protect the wearer's feet and pursue the convenience of wearing, but if the air permeability is not secured, the shoes sweat and the smell of the feet is generated due to the heat generated from the feet. After all, one of the important components of shoes can be said to solve the problems caused by effectively dissipating heat or sweat generated from the feet.

In order to solve this problem, conventionally, a technology has been proposed in which air can be discharged through the insole by forming an air hole through which an air can be discharged on the side or bottom surface of the outer shell where the surface is exposed. Shinan No. 20-0192510 (Air exhaust shoes), Patent Publication No. 10-2000-0035118 (Shoe insole with air hose installed), and Patent No. 10-0470751 (Shoes with air circulation to the outside) For example. However, these prior arts cannot be prevented from entering water into the shoes when water is accumulated on the ground because the ventilation is made through the bottom of the shoes or the side of the shoes, and a very fatal weakness to shoes that require waterproof function, such as boots Can act as

Accordingly, the present inventor has proposed a dual-structured shoe with a through hole formed in the inner skin and the outer skin so that air can be discharged through the instep and the ankle. This is registered patent publication No. 10-1737910 (breathable shoes having a double structure on the upper part) and patent registration number 10-1711881 (sulfo breathable shoes), publication 10-2017-0122645 (double on the upper part) It has been disclosed through a breathable shoe having a structural part), and also disclosed in Patent No. 10-1767884 (a method for manufacturing breathable boots).

However, since this prior art forms an integral structure of a double structure in which air can be discharged between the outer skin and the inner skin, there is a difficulty in considering a dual structure for discharging air from the design of the shoe to the manufacturing. There is a disadvantage that has a certain limit in the effective discharge of sweat.

Although not defined differently, all terms including technical terms and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present invention pertains. Commonly used dictionary-defined terms are further interpreted as having meanings consistent with related technical documents and currently disclosed contents, and are not interpreted as ideal or very official meanings unless defined.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1A is a cross-sectional view of an inner shoe in a prefabricated shoe having a dual structure with improved breathability according to an embodiment of the present invention, and FIG. 1B is a cross-sectional view of an inner shoe inserted into an outer shoe.

The prefabricated shoes of the present invention consist of an inner shoe that can be worn on a user's foot and an outer shoe that can couple the inner shoe 100 therein.

First, referring to FIG. 1A, the inner shoe 100 constituting the prefabricated shoe of the present invention may have a structure of a shoe that the body 110 can wear on the user's foot by itself, but an exercise or activity process A hot air outlet 120 for discharging heat generated from the foot, or a water outlet that is not shown in the drawing but can discharge sweat to the bottom may be provided. The hot air outlet 120 or the moisture outlet constituting the inner shoes 100 will be described in more detail below.

The body 110 of the inner shoes 100 may be made of a material such as natural rubber, synthetic rubber, or synthetic resin. For example, non-toxic, excellent chemical resistance, excellent insulation, polyethylene (PE), light resistance, chemical resistance, excellent electrical insulation, polyvinyl chloride (PVC), non-adhesive, non-oily and high insulating thermoplastic With rubber, cold resistance and TPR (Thermoplastic Rubber) that is resistant to acids and alkalis, excellent heat resistance and flexibility at low temperatures, SBS (Styrene butadiene styrene), SEBS (Styrene ethylene butylene styrene) or EPDM (Ethylene propylene diene M-class) It can be done. In addition, it may be made of rubber or foam resin such as SEPS, SEEBS, SEEPS, EVA, TPU, PU, PS, PP, TPO, TPV. In addition, it may be made of a fabric such as leather or Gore-Tex of a certain thickness to be detachable inside the outer shoe 200. That is, the body 110 of the inner shoe 100 may be used as long as it is a material having elasticity or elasticity so that it can be inserted and fitted inside through the entrance of the outer shoe 200.

The outer shoe 200 may be fixed by inserting an inner shoe 100 worn on a user's foot. Inner shoes 100, because the diameter of the ankle, or the surface area from the toe to the heel is smaller than that of the outer shoes 200, a user applies the force of a certain size to the inner shoes 100 to the inside of the outer shoes 200 Can be pushed on.

1B shows a cross-section when the inner shoe 100 is inserted into the outer shoe 200 as described above. The inner shoes 100 inserted into the outer shoes 200 may be adhered to and fixed to a part of the inner surfaces of the outer shoes 200 by frictional force of a surface having elasticity or elasticity.

At this time, the outer surface of the inner shoe 100 and the inner surface of the outer shoe 200 may be in close contact in some areas, but some other areas may be spaced apart to a certain extent. It may serve as a discharge passage 150 through which heat or sweat moisture generated inside can be discharged to the outside. Therefore, in the state in which the inner shoes 100 are inserted and fixed to the outer shoes 200, the heat or sweat moisture generated during a user's exercise or activity is between the inner shoes 100 and the outer shoes 200. It may be discharged through the discharge passage 150 formed in. As a result, the user wearing the prefabricated shoes of the present invention can reduce discomfort due to heat or sweat generated from the feet.

At this time, the outer shoe 200 is preferably made of a waterproof material so that the heat or sweat generated from the user's foot is discharged to the outside, and water or the like existing outside does not flow inside. Therefore, here, it will be described on the assumption that the waterproof effect is required, such as boots or restaurant cooking shoes or boots. However, the present invention is not limited to the case of such boots or boots, and may be applicable to all types of shoes that require a waterproof function from the outside. The material constituting the body of the outer shoe 200 may be made of a material such as natural rubber, synthetic rubber, or synthetic resin, like the inner shoe 100. Polyethylene (PE), polyvinyl chloride (PVC), thermoplastic rubber, Thermoplastic Rubber (TPR), Styrene butadiene styrene (SBS), Styrene ethylene butylene styrene (SEBS) or Ethylene propylene diene M-class (EPDM) It can be done. In addition, it may be made of rubber or foam resin such as SEPS, SEEBS, SEEPS, EVA, TPU, PU, PS, PP, TPO, TPV. In addition, the inner shoes 100 may be made of a fabric such as leather or Gore-Tex of a certain thickness so that they can be inserted therein. That is, the outer shoe 200 may be used as long as it is a material having elasticity or elasticity so that the inner shoe 100 is inserted and fitted therein.

As described above, since the inner shoes 100 and the outer shoes 200 are detachable in the prefabricated shoes of the present invention, the inner shoes from the outer shoes 200 after the user completes the work by wearing the prefabricated shoes of the present invention By separating (100), it is easy to wash or clean foreign substances such as water and moisture attached to the inside and outside of the inner shoe 100 and the inside and outside of the outer shoe 200.

Hereinafter, in the prefabricated shoes of the present invention, the various configurations of the inner shoes 100 and the outer shoes 200 will be described in more detail.

2A and 2B are plan views illustrating inner shoes equipped with a hot air outlet in a prefabricated shoe having a dual structure with improved breathability according to an embodiment of the present invention.

FIG. 2A shows a case where the hot air outlet 120 is formed of a circular single vent hole on the user's instep. Since the heat generated from the user's feet during exercise or activity is composed of light gaseous components, since it is discharged in the upward direction of the feet, the hot air outlet 120 for discharging heat is formed in the instep portion that can be directed upward. It is preferred. However, if the hot air outlet 120 is formed too large, the instep portion located in the hot air outlet 120 may be rubbed against the inner surface of the outer shoe 200 in the state where the inner shoes 100 are inserted into the outer shoes 200. It may be desirable to form such a size that friction does not occur.

2B shows a case in which the hot air outlet 120 is configured by forming a plurality of small vent holes 121 at the user's instep. 2B, when the hot air outlet 120 is configured using a plurality of small vent holes 121, the entire open area may be smaller than in FIG. 2A, but the user's instep is exposed to the outside through the hot air outlet 120. Since the possibility of friction between the inner surface and the instep of the outer shoe 200 is reduced, there is an advantage to increase the safety for the user.

3 is a prefabricated shoe of a dual structure with improved breathability according to an embodiment of the present invention, showing a cross-sectional view when heat is discharged through a discharge passage in a state in which an inner shoe equipped with a hot air outlet is coupled to an outer shoe .

Referring to FIG. 3, when the inner shoes 100 in which the hot air outlet 120 is formed are coupled to the inside of the outer shoes 200, the heat generated from the feet during the exercise or activity process of the user is the inner shoes 100 It may be discharged between the inner shoes 100 and the outer shoes 200 through the hot air outlet 120. The hot air outlet 120 may be formed of a single vent hole formed in the instep portion as described above, or may be formed of a plurality of small vent holes. In particular, the heat generated during exercise or activity shows a warm temperature when generated by the user's feet, and thus moves upward. Therefore, the hot air outlet 120 formed in the instep portion allows the heat generated from the side of the foot or the foot, including the instep portion, to be easily discharged to the outside of the inner shoe 100.

While the inner shoes 100 are inserted into the outer shoes 200, some of the surfaces of the inner shoes 100 may contact the inner surfaces of the outer shoes 200 by friction. At this time, the area contacted between the inner shoes 100 and the outer shoes 200 may be greatly influenced by a difference in diameter and size of the inner shoes 100 and the outer shoes 200. For example, when the difference between the ankle portion diameter of the inner shoe 100 and the ankle portion diameter of the outer shoe 200 is 5 mm or less, the outer surface of the inner shoe 100 and the outer shoe 200 by attraction force due to friction force The inner surface of the can be in contact with a significant portion. Accordingly, the inner shoes 100 and the outer shoes 200 may be formed such that a discharge passage 150 through which heat can be discharged may be formed between the outer surface of the inner shoes 100 and the inner surface of the outer shoes 200. It is desirable to determine the diameter and size.

The heat between the outer surface of the inner shoe 100 and the inner surface of the outer shoe 200, in particular the outer surface connecting the ankle from the instep of the inner shoe 100, and the inner surface of the outer shoe 200 adjacent thereto When the discharge passage 150 is formed in a space such that air can be moved, heat from the hot air outlet 120 of the inner shoes 100 may be easily discharged to the outside through the discharge passage 150.

In addition, the inner shoes 100 or the outer shoes so that the gas generated by the vaporization of the heat discharged through the hot air outlet 120 of the inner shoes 100 or the moisture discharged through the moisture outlet 200 can be effectively discharged ( It is also possible to additionally form a member for the discharge passage in 200).

Referring to FIG. 11, when the inner shoe 100 in which the discharge groove 131 is formed is coupled to the inside of the outer shoe 200, sweat or moisture generated from the foot during a user's exercise or activity process may affect the user's foot. It rides and flows down, and can be gathered to the bottom portion of the outer shoe 200 through the discharge groove 131 of the inner shoe 100. As described above, the discharge groove 131 may be formed of a discharge groove 131 having a linear or circular shape formed on the sole portion of the user. In particular, since sweat or moisture generated in the course of exercise or activity is a liquid component, it flows downward due to its weight, so it is effective to form the discharge groove 131 on the sole portion of the inner shoe 100. In addition, the water discharged through the discharge groove 131 is not compressed between the bottom surface of the inner shoe 100 and the bottom surface of the outer shoe 200, so that it can accumulate on the inner bottom surface of the outer shoe 200 As described above, it may be effective to form the inner bottom surface of the outer shoe 200 in a curved shape.

While the inner shoes 100 are inserted into the outer shoes 200, some of the surfaces of the inner shoes 100 may contact the inner surfaces of the outer shoes 200 by friction. At this time, the outer bottom surface of the inner shoes 100 and the inner bottom surface of the outer shoes 200 may be in contact, but in general, the shoe is not formed in a flat shape, and the toe portion and the metatarsal bone follow the user's foot flexion. , And the heel portion is in close contact with the floor, the arch portion between the metatarsal and heel has a convex structure from the ground. In addition, since the toe, metatarsal, and heel portions do not contact the floor at the same time, the bottom surface of the inner shoes 100 and the outer shoes 200 are sequentially contacted with the ground during a user's walking or exercise process. The bottom surface is partially alternating between contact and non-contact.

Therefore, moisture accumulated on the bottom surface of the outer shoe 200 through the discharge groove 131 is vaporized as a gas component over time, and the bottom surface of the inner shoe 100 and the bottom surface of the outer shoe 200 After moving along the non-contact space, it may be discharged to the outside through the discharge passage 150 formed between the inner shoes 100 and the outer shoes 200.

In addition, in consideration of the case where the sweat or moisture discharged through the discharge groove 131 collects on the bottom surface of the outer shoe 200, the inner shoe 100 of the prefabricated shoe of the present invention, the bottom surface of the inner shoe 100 And it may further include a member that can form a space for collecting moisture between the bottom surface of the outer shoe 200. Such a member may be formed as a protrusion protruding downward in the bottom surface of the inner shoe 100, or may be formed as a protrusion protruding upward in the inner bottom surface of the outer shoe 200.

12 is a prefabricated shoe of a dual structure with improved breathability according to an embodiment of the present invention, showing a cross-sectional view when the inner shoe provided with a bottom projection is coupled to the outer shoe, and FIG. 13 is an outer provided with a bottom projection It is a sectional view showing a case where an inner shoe is combined with a shoe.

First, referring to FIG. 12, in the inner shoe 100 of the prefabricated shoe according to the embodiment of the present invention, a straight or circular discharge groove 131 may be formed on the bottom surface. The sweat or moisture generated in the sole portion is collected on the bottom surface of the outer shoe 200 through the discharge groove 131, but when the bottom surface of the inner shoe 100 and the bottom surface of the outer shoe 200 are in contact, the bottom Sweat or moisture accumulated on the surface may be introduced into the inner shoes 100 again through the discharge grooves 131 of the inner shoes 100. To prevent this, a bottom protrusion 132 may be attached to the bottom surface of the inner shoe 100 in a downward direction. The bottom protrusion 132 prevents the outer bottom surface of the inner shoes 100 from contacting the inner bottom surface of the outer shoes 200, and the outer bottom surface of the inner shoes 100 and the inner bottom surface of the outer shoes 200 It provides a space for sweat and moisture to gather between the sides.

In order to effectively discharge sweat and moisture and prevent it from re-introducing, the bottom protrusion 132 formed on the bottom surface of the inner shoe 100 is located in a portion where the discharge groove 131 through which sweat or moisture is discharged is not formed. It is preferred. Therefore, when the water outlet 130 is made of a straight discharge groove, a plurality of floor protrusions 132 may be formed at regular intervals along a space where the discharge groove 131 is not formed. When the water outlet 130 is formed of a circular discharge groove, the size and position of the bottom protrusion 132 may be determined in consideration of the space and area where the discharge groove 131 is not formed. The bottom protrusion 132 may be formed in a semicircle shape or a square shape, or may be formed in various other shapes.

The sweat or moisture collected by the space formed by the bottom protrusion 132 of the inner shoe 100 vaporizes as a gas over time, and the vaporized gas is the outer surface of the inner shoe 100 and the outer shoe 200 It may be discharged to the outside through the discharge passage formed between the inner surface of the.

13, the bottom protrusion may be formed on the inner bottom surface of the outer shoe 200.

At this time, when the bottom projection 232 is formed on the inner bottom surface of the outer shoe 200, it is preferable to arrange it so as not to block the discharge groove 131 of the inner shoe 200. Accordingly, in this case, a pair of inner shoes 100 and outer shoes 200 will be configured to have positions corresponding to each other in consideration of the shape and position of the discharge groove 131 of the inner shoes 100. Even when the bottom protrusion 232 is formed on the inner bottom surface of the outer shoe 200, sweat or moisture flowing out from the inner shoe 100 accumulates on the bottom surface of the outer shoe 200, and becomes a gas over time. It may be vaporized and discharged to the outside through the discharge passage.

At this time, the bottom protrusion 232 formed on the inner bottom surface of the outer shoe 200 may have various shapes, for example, it is formed in a lattice shape as shown in FIG. 14A, where moisture or water is collected between square grooves or , As shown in FIG. 14B, moisture or moisture may be collected by the bottom protrusion formed in a honeycomb shape.

On the other hand, such a bottom protrusion may be formed on the outer bottom surface of the inner shoe 100 or may be formed on the inner bottom surface of the outer shoe 200, the inner bottom surface of the inner shoe 100 and the inner portion of the outer shoe 200 It may be formed together on the bottom surface.

In the prefabricated shoes of the present invention, when the bottom surface of the inner shoe 100 is in close contact with the bottom surface of the outer shoe 200, such as sweat discharged downward through the discharge groove 131 of the inner shoe 100 It may be difficult to discharge or vaporize moisture to the outside. To this end, the prefabricated shoes of the present invention may be further provided with an exhaust pump between the outer bottom surface of the inner shoe 100 and the inner bottom surface of the outer shoe 200.
