Durable Skin Shoes {Strong skin shoes}

More particularly, the present invention relates to a skin shoes having enhanced durability. More specifically, the present invention relates to a skin shoe having durability enhanced, and more particularly, to a footwear which is formed by stretch- The present invention relates to a durable skin shoes which does not detach.

In general, shoes are used as a very important means of determining the health and walking habits of the feet while protecting the feet.

These shoes have been developed in various ways and have various functions and various shapes, and they are standardized and mass-produced by each manufacturer.

The shoe is usually made of different material or the same material as the sole, the middle, and the insole fixed from the bottom surface, and the upper having a predetermined shape is fixed to the upper side of the outer surface of the sole.

Then, the insole is detachably attached to the upper part of the insole constituting the shoe, or the insole is interposed between the insole and each manufacturer.

Meanwhile, conventionally, as a leisure activity becomes more common, a variety of shoes suitable for activities are being produced. Especially, when enjoying water leisure, many people substitute slippers or sandals for breathability, water is well- I would like to enjoy the activity of aqua shoe kind.

In general, these aquashuzes are characterized by a good grip and light weight, as well as wearing socks, and are made of a tough material to protect their feet sufficiently in the ground and under water, and are easy to wash.

Next, conventionally known techniques will be described by way of example.

1 is a perspective view of an aquashure disclosed in Korean Laid-Open Utility Model Publication No. 20-2012-0007877. The conventional art is made of a flexible synthetic resin material and has an insertion portion 10, 20 And an opening 40 is formed at a lower side of the insertion portions 10 and 20 so that the insertion portions 10 and 20 are inserted into the insertion portions 10 and 20, The front portion of the foot can be pulled out through the opening portion 40 in a fixed state. The insertion portions 10 and 20 include a sole insertion portion 10 in which the sole portion is inserted, And a toe insertion portion 20 to which the toe is inserted. The opening portion 40 is formed on the lower side of the foot insertion portion 10.

Such a conventional technique is in the form of a simple flipper, which is configured to be watery in water. However, since a part of the soles of the foot is opened to touch the ground, when walking on the sea or the white sand of the river or the rock of the valley, It is difficult to protect the soles from the risk of burning of the soles due to skin, sharp stones, and high temperature sand in children, and since the toes are formed in the form of flippers, they are difficult to use on the ground.

In addition, referring to FIG. 2, a footwear exclusive use footwear of the Korean Registered Utility Model No. 20-0330755 which is designed to protect the soles of the foot is made of a silicone material having elasticity or elasticity so as to be worn on the foot The bottom part 1 is formed thicker than the wool (upper) part 2 while having an inner skin 3 and a contact ring 4 and a webbing 20 on the front side And the like.

However, since the shoes for exclusive use of vacation are formed of silicone material, it is difficult to drain water or dry quickly, so that there is a problem that when the skin is worn for a long period of time, the skin tends to be scratched by moisture.

In addition, there is a problem that the webbing is integrally formed and is hardly worn on the ground like the aqua shoes described in the above-mentioned Korean Utility Model Publication No. 20-2012-0007877.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a sewing machine for a sewing machine, So that the sewing line is prevented from breaking even in a severe activity amount, and it is an object of the present invention to provide a skin shoes having enhanced durability.

In order to achieve the above-mentioned object, the present invention provides a wearer comprising: a wearable portion formed of a stretchable cloth and having an opening for putting a foot thereon; And a shoe sole attached to a bottom surface of the wearer to be integrally formed with the shoe sole.

The foot portion may include a foot portion having an upper surface that is in contact with the foot, a width gradually narrower toward the rear, and a heel portion that is vertically extended to support the heel at a rear end thereof. And a lid part which is sewn together around the foot part and is sewn to the heel part at the rear end thereof so as to cover the foot with the opening part formed at the upper part thereof.

Further, the soles are molded on the bottom surface of the wearer and are integrated with the wearer.

And the shoe portion is formed to be wider than the foot portion to receive the lower portion of the foot portion and the lid portion.

And a slip prevention protrusion is formed on a bottom surface of the soles.

The present invention provides the following effects.

First, since the outsole is mold-molded so that the sewing line is not exposed to the outside of the wearer's lower part, the sewing line does not pop up even in a severe activity amount.

Second, since the wear part is formed as a stretchable genuine material so as to surround the foot, it can be protected without being peeled off from the foot.

Third, even if it is worn in water for a long time, it is easy to drain off when coming to the ground, and it is dried easily, so that the effect is not caused by moisture.

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

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

3, the durability-enhanced skin shoes according to the present invention include a wearer 100 and a shoe sole 200.

At this time, the wearer 100 is made of a cloth having stretchability and air permeability.

Particularly, the wearer 100 is cut and formed in a cylindrical shape so that the wearer 100 can be put on the foot.

That is, the wearing portion 100 is a shoe upper having an opening portion 111 opened at an upper portion thereof, so that the wear portion 100 sandwiched between the forefoots through the opening portion 111 sequentially covers the foot portion. The wearer 100 has a structure in which the wearer 100 wears in the form of wrapping an ankle (including a foot).

As shown in FIGS. 4 to 5, the wearer 100 is formed in such a manner that the soles contact with the upper surface of the wearer 100 and the width gradually decreases toward the rear of the wearer 100, and the heel is supported at the rear end A foot part 120 including a vertically extending heel part 121 and a foot part 120 sewn along the foot part 120 and a rear end sewn together with the heel part 121, And a lid 110 which is formed to cover the foot.

On the other hand, a tightening band 112 may be attached to the opening 111 to be fixed to the foot.

Since the tightening band 112 is a general content, detailed description will be omitted.

On the other hand, since the footrest 120 and the lid 110 are tightly sewn together, a thick sewing line L is formed as shown in FIGS.

Thus, the wearing part 100 including the foot part 120 and the lid part 110 has a structure to be worn in the form of wrapping around the ankles (including the foot).

Further, since the heel portion 121 is generally applied to a shoe, a detailed description thereof will be omitted.

Next, the shoe sole 200 is made of a stretchable material, that is, a shoe sole 200. At this time, rubber is preferably used as the preferred sole 200.

Meanwhile, there is no particular limitation on the shape of the shoe sole 200, but it is preferable to have the shapes shown in Figs. 6 and 7. The bottom surface 250 of the shoe sole 200 has a flat shape so that a large area of the bottom surface thereof can be in contact with the ground, and a slip prevention protrusion 210 is formed to prevent slippage.

In addition, when the soles 200 are formed for mass productivity, uniformity, etc., the mold is preferably molded through a mold, and the manufacturing method will be described in detail.

In addition, in the illustrated example, the shoe sole 200 is illustrated as having a plurality of non-slip protrusions 210 formed therein. However, this is merely one example of the preferred embodiment, I will do it.

Such durable skin shoes can be manufactured in the form of the example of Fig.

According to Fig. 8, the skin shoes with enhanced durability can be automatically manufactured while the mold 300 rotates on the conveyor belt C. Fig.

For example, in the manufacturing method according to the present invention, the fixing step of the wearing portion 100 is first performed.

The fixing step of fixing the wearing part 100 includes fixing the wearing part 100 formed by sewing the foot part 120 and the lid part 110 to a fixture (not shown) provided at the inner center of the upper frame 320 .

Accordingly, when the wearer 100 is fixed, the bottom surface of the wearer 100 faces the ceiling so as to attach the wearer 100 and the shoe sole 200.

When the mold 300 is positioned below the injection hopper H containing the sole solution F, the lower hopper 310 is rotated from the injection hopper H to the lower hopper 310, And the sole filling fluid (F) is injected into the solenoid charging cavity (312).

Since the liquid injecting step is controlled by a controller (not shown) of the system in a time control manner or the like, injection is completed before the mold 300 located below the injection hopper H is completely discharged during the index time.

Thus, when the liquid injection is completed, the upper mold 320 is rotated toward the lower mold 310 to close the mold 300 and the mold 300 is reversed.

The combining step is a step of bonding the sole 200 to the bottom surface of the wearing part 100 made of cloth so as to form the sole part 200. The reason for turning the mold part 300 upside down is that the sole part 200 And the wearer 100 is positioned below the wearer 100, so that more uniform and firm attachment of the mold 300 to the gravity is achieved due to the mold-forming force and the gravity of the mold 300.

In this case, since the wearing portion 100 is made of a cloth material, the porosity differs depending on the type of cloth. Therefore, when the mold is formed, the sole solution F, which is a rubber liquid, It can leak.

However, when the solefilling solution F sucks, a part of the sole solution F hardens on the inner side of the wearer's body 100, so that the sole solution F comes into contact with the soles of the wearer when worn.

Therefore, in such a case, it is preferable to apply a waterproofing agent to the inner surface of the wearer 100 in advance to prevent the liquid from leaking before fusion.

Thereafter, a curing step is performed in which the mold 300 is fixed while passing through the heating zone 400.

The curing step is a step in which heat is applied to the cured product through the heating zone 400 so as to be hardened by curing. It should be noted that the curing process is accompanied by a cooling process which is not necessarily quenched and must be slowly cooled .

If it is quenched, productivity may be improved, but cracking or non-sticking may be caused, resulting in a higher product defect rate.

Particularly, as the most preferable curing condition, the temperature of the heating zone 400 is maintained at 20-60 DEG C, and the process rotation time is most preferably 10-20 minutes.

In this case, if the temperature of the heating zone 400 is lowered to less than 20 ° C, the quality of the sole solution (F) hardens rapidly, and if it exceeds 60 ° C, It can not be processed in time and the cost is increased. Therefore, it should be limited to the above range.

Thus, when the curing is completed, the product separation step is performed.

The product separating step is a process of extracting the cured product by opening the mold 300.
