Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a footwear outsole having improved breathability using a water-

The present invention relates to a footwear outsole generally referred to as a shrine or a ladies' dress, shoes and casual shoes. More specifically, the present invention relates to an outsole for a footwear, The water repellent leather fabric is heated and compressed using a solid adhesive mesh and the ventilation hole is formed in the bottom portion of the recessed portion with the mesh filter inserted, And to solve the problems such as clogging of pores or clogging of air holes due to sand or soil that can flow from the bottom of the outsole.

In general, men's and women's formal shoes or shoes such as sneakers, leisure shoes, and hiking boots are essential items in everyday life and have various designs and functions according to the user's taste or purpose.

Such a shoe should have a good fit, but it should also alleviate the fatigue of the foot. The shoe has a technical characteristic of minimizing the pressure feeling by effectively dispersing the weight even if it is worn for a long time.

Such shoes generally include an out sole that is directly rubbed against the ground, a mid sole attached to the upper surface of the outsole, and an insole that is attached to the upper surface of the midsole and is in contact with the wearer's foot, And an upper which is attached or adhered using the outsole.

Here, the outsole, which is a floor window, is generally manufactured by foam molding of polyurethane or the like, and the outsole must have a predetermined elastic force and a shock absorbing property. In addition to the elasticity and shock absorbing properties, it will be required to have abrasion resistance to prevent shortening of service life due to frequent friction with the ground and chemical resistance to prevent physical properties from various contaminants.

However, it is general that the above-mentioned shoe outsole for general use is made of usual raw rubber or rubber mixture, and the shoe outsole does not sufficiently satisfy shock absorption, abrasion resistance and chemical resistance required by the consumer It is true.

In particular, since most of the shoes have an enclosed internal space (technically speaking, air communication and circulation are not free), the athlete's foot or bad smell Outsoles with various measures and advanced components are being developed.

In such an air-permeable outsole, pumping means for forcibly supplying outside air into the inside of the shoe is generally used, or it is common for shoes to form a fine hole by punching on the upper or outsole. Shoes are difficult to use when it comes to rain, and they are often used only in dry or sunny weather.

Accordingly, in order to solve the above-mentioned problems, it is required to provide a light and soft fit feeling as well as to secure excellent breathability and improve visual psychological effect due to a ventilation hole having a relatively large inner diameter as in the registered patent No. 10-0865936, It is possible to maintain a comfortable wearing state by securing excellent permeability and breathability in addition to complete blocking of water and to be harmless to the human body because it is adhered through heat fusion and by using an environmentally friendly material in which the antibacterial property and environmental hormone are not detected, And the shoe window has been registered and registered.

In addition, Japanese Patent Application No. 10-0886792 discloses a method of manufacturing an outsole having an outsole formed by molding a raw material mixed with an oil-resistant material, forming a vent hole having a relatively large size on the outsole, And a functional blowing resin are successively laminated on the outer surface of the midsole, and a breathable sponge is inserted and formed in the midsole to ensure ventilation and waterproofing by the oil-resistant and functional blowing resin. And the breathable sponge has been registered and registered with an oil-resistant shoe sole that is light in weight of the entire shoe while providing a comfortable feeling of comfort while exhibiting excellent breathability.

In addition, a vent hole having various shapes and sizes is formed on the upper part of the dress shoes. The vent hole is formed by passing through both the outer shell and the inner core. Between the outer shell and the inner core, And a cut-out portion in which the water repellent fiber paper is exposed is formed in an intermediate portion excluding the edge of the inner skin, and a skin, a water-repellent isher, and an inner skin are formed on the side of the dress shoes, Water and water-repellent functions, and also has a ventilation, room, and water-repellent function which is intended to overcome the problems of conventional formal shoes due to excellent air permeability, A method of manufacturing an upper and an upper shoes for shoes having been proposed and registered.

In the case of Patent No. 10-0933084, an outsole is formed by mixing an abrasion-resistant material and a non-slip material with a polyurethane excellent in impact absorbability, abrasion resistance and chemical resistance, and the polyurethane outsole is provided with a ventilation groove And a ventilation hole communicating with the ventilation groove is continuously arranged from the side of the outsole to form a polyurethane outsole for shoes having excellent breathability, which is reasonably overcome the problems of the conventional footwear outsole. It has been registered.

However, in the case of a conventional outsole, that is, an outsole in which a plurality of air holes are formed in the outsole so as to have air permeability, foreign substances such as sand or soil are continuously introduced into the air holes, and these foreign substances block the air holes, It is weakened or the air permeability is lost.

In addition, foreign matter such as sand or soil introduced into the vent hole penetrates to the upper part of the outsole through the vent hole, thereby generating a gap between the outsole and the water repellent member, thereby causing the waterproof function to be lost, It has a very short life span.

Further, in the case of the conventional ventilated outsole, a large amount of adhesive is used in fixing the water repellent member to the upper part of the outsole. Such an adhesive often blocks the vent hole in the process of adhering the vent member, So that the air circulation effect is extremely weak.

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

FIG. 1 is a block diagram of a footwear outsole according to the present invention, FIG. 2 is an exploded perspective view of a footwear outsole according to the present invention, FIG. 3 is an overall sectional view of a footwear outsole according to the present invention, FIG. 5 is a partially enlarged cross-sectional view of a footwear outsole according to the present invention. FIG.

First, the outsole for footwear according to the present invention comprises an outsole 10 formed by using a material having excellent elasticity, abrasion resistance and chemical resistance, such as polyurethane, and a metal netting or synthetic resin netting, , A mesh filter (20) composed of a mesh so that foreign substances such as sand and earth can be blocked, a fixed guider (30) made of a soft resilient material such as polyurethane and a hot melt resin An adhesive mesh 40 and a water repellent leather fabric 50 made of artificial or natural leather.

At this time, the outsole 10 is formed with a concave recess 11 at the upper part of the forefoot portion of the wearer's foot or the forward portion of the sole of the wearer. In the recess 11, And the adhesive grooves 13 are formed at the edge of the bottom surface of the recess 11 in a predetermined depth.

The mesh filter 20 is formed to have the same or smaller size as the bottom surface of the recessed groove 11 except for the adhesive groove 13 which is seated in the recessed groove 11, Should not penetrate the adhesive groove 13 and should be able to completely cover the air holes 12 and 12 'of the recess 11.

In addition, it is more preferable that the fixed guider 30 is made of a material having superior resilience and flexibility as compared with the outsole 10 as a body that receives most of its body weight through the sole of the wearer. Circulation holes 31 and 31 'having the same positions as those of the air vent holes 12 and 12' are arranged in the insertion groove 32 in a vertical penetration manner .

Particularly, the fixed guider 30 is inserted into the recessed groove portion 11, and the adhesive projection portion 33 corresponding to the adhesive groove portion 13 of the recessed groove portion 11 is positioned at the bottom edge of the fixed guider 30, And the amount of downward protrusion of the adhesive protrusion 33 is slightly shorter than the depth of the adhesive groove 13 so that the adhesive liquid 14 is applied to the adhesive groove 13, So that the outsole 10 and the fixed guider 30 can be adhered and fixed in close contact with each other through the liquid 14.

The adhesive mesh 40 is made of a low temperature melting hot melt resin or the like and the adhesive mesh 40 is seated in the insertion groove 32 of the fixed guider 30. [ In addition, the adhesive mesh 40 must be in a molten state to such an extent that the fixed guidder 30 or the water repellent leather fabric 50 is not thermally deformed, and is formed by using a low-temperature hot melt which is melted at a temperature of 60 to 80 캜 It is also possible to use a hot-melt resin which can be instantly melted at a temperature of 120 ° C or later, if necessary.

In addition, the water-repellent leather fabric 50 is made to be able to communicate air freely, while blocking water and foreign matter. Using the water-repellent leather material 50, And the fresh air can be continuously introduced through the outsole 10, so that it can be worn in a more pleasant state. In the course of walking, rainwater, sand, Foreign matter or the like is prevented from flowing into the inside.

The waterproof water-repellent leather fabric 50 is preferably a PITARD-WR100 manufactured by Pittard of the United Kingdom. The leather fabric of the PITAD company has breathability of the leather fabric itself, Is known to have a breathable and water repellent function during the presence of a leather product by adhering the hydrofibric raw material to fine particles of leather.

Also, since the above-mentioned PITAD-WR100 is processed by a processing method, that is, a highly water-repellent method, the leather is permanently retained even if the leather is cut in all directions and the surface is wounded. In case of attempting to realize water repellent function through the silicone back treatment, if the leather is flawed or if it is used continuously, the water repellent treatment is broken in the wet or wrinkled part, so that the function is not maintained. However, The leather fabric 50 improves upon this problem. When applied to the outsole of the present invention, the leather fabric 50 can continuously perform both the breathability and the water repellent function even when the water is wet or bended.

As a result, after the manufacturing process of the individual member for producing the outsole 10, the mesh filter 20, the fixed guider 30, the adhesive mesh 40, and the water repellent leather fabric 50 as described above, An adhesive agent for applying or injecting the adhesive liquid 14 into the adhesive groove 13 in the interior groove 11 is subjected to a filter setting process for inserting the mesh filter 20 into the upper side groove 11 of the housing 10, The coating process may be performed.

At this time, the filter-laying process and the adhesive-applying process may be carried out mutually alternately. In this state, the mesh filter 20 is placed on the bottom of the recess 11 in a state where the adhesive liquid is applied first. You can also do that.

Next, after the mesh filter 20 is subjected to the laying process and the adhesive applying process, the fixed guider 30, which is attached to the orifice groove 11 of the outsole 10, is placed, The adhesive protrusions 33 protruding from the bottom surface of the fixed guider 30 are inserted into the adhesive grooves 13 of the recess 11 and adhered to each other by the adhesive liquid 14, The mesh filter 20 is inserted between the upper surface of the recessed groove 11 and the bottom surface of the fixed guider 30 and the air holes 12 and 12 'formed in the outsole 10 are inserted The air introduced through the mesh filter 20 is freely communicated to the circulation holes 31 and 31 'of the fixed guider 30 while the air introduced into the air holes 12 and 12' Various foreign substances are blocked by the mesh filter 20 and circulated through the circulation holes 31 and 31 'of the fixed guider 30 Will not be introduced.

The air holes 12 and 12 'formed in the outsole 10 are formed to have an inner diameter sufficient to allow foreign matter such as inflowing sand to easily escape from the air holes 12 and 12' Since the holes 31 and 31 'are made to discharge only hot and humid air inside the shoe, they are manufactured to have a relatively small inner diameter as compared with the air holes 12 and 12' It is possible to prevent the pores 12 and 12 'from being clogged so that the air can be freely communicated.

After the stitching and bonding process is performed on the fixed guider 30 as described above, a process of placing a separate adhesive mesh 40 in the insertion groove 32 formed in the upper portion of the fixed guider 30 is performed The adhesive mesh 40 is made of a lattice type solid adhesive and is spaced apart from the circulation holes 31 and 31 'formed in the insertion groove 32 When the adhesive mesh 40 is placed in the insertion groove 32, the circulation holes 31 and 31 'are exposed and opened between the meshes of the adhesive mesh 40.

The water repellent leather fabric 50 is placed inside the insertion groove 32 so that the water repellent leather fabric 50 presses the adhesive mesh 40. In this state, The waterproof waterproof leather 50 is heated while the adhesive mesh 40 located at the bottom is heated and the solid adhesive mesh 40 is heated, (40) is brought to a molten state.

Therefore, the adhesive mesh 40, which is melted at a high temperature, is formed in the insertion groove portion 32 of the fixed guider 3 in a state in which the water repellent leather material 50 is firmly fixed in the state where the circulation holes 31 and 31 ' Since the circulation holes 31 and 31 'are in close contact with the water repellent leather fabric 50, the air inside the shoe can be discharged smoothly or the air can flow smoothly into the air outside the shoe. You can.

Accordingly, the footwear outsole according to the present invention absorbs the weight and load of the wearer, which acts on the outsole of the shoe, primarily by the relatively fixed rigid guider 30 to provide a load dispersion and a cushioning feeling. The hot and humid air due to wearing is discharged to the outside along the circulation holes 31 and 31 'and the air holes 12 and 12' through the water-repellent leather fabric 50. At the same time, External air flows into the inside of the shoe along the vent holes 12 and 12 'and the circulation holes 31 and 31' according to the pressure difference between the shoes and the outside which occur during walking or exercising. It is possible to obtain better fit by discharging sweat and smell.

Particularly, since the mesh filter 20 blocks foreign substances such as sand or soil that may flow from the bottom of the outsole 10, it is possible to prevent the bottom of the water repellent leather fabric 50 from being lifted or contamination of the inside of the shoe The adhesive mesh 40 can faithfully perform the waterproof and water-repellent function of the water-repellent leather fabric 50, and at the same time, the water-repellent leather fabric 50 is adhered to the circulation hole 31 ) 31 'can be prevented from being clogged, so that it is possible to continuously maintain the excellent air permeability.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the present invention as defined by the appended claims. Examples should be understood.
