Description

Breathable athletic shoes {Ventilative athletic shoes}

The present invention relates to a breathable sneaker, more specifically, in a conventional sneaker consisting of the sole, midsole, insole, upper, forming a half-moon-shaped groove that can be installed on the both sides of the midsole inlet tube, the outside air, On the inner side of the midsole is formed an air passage connected to the half-moon groove, and through the air passage to supply air to the inside of the sneakers (especially the sole) to maximize the ventilation, of course by supplying fresh air The present invention relates to breathable sneakers that not only prevent the production of diseases such as athlete's foot, but also have a function of absorbing the impact of the user's weight when walking.

In general, there have been many structural or technical developments in sneakers, but the concept of protecting the feet from the outside, which is the basic purpose of sneakers, has not been greatly deviated. In addition, there have been many developments such as texture, ventilation, and waterproofing, but the outsole that binds the upper and protects the bottom of the foot has always been limited by the basic concept of waterproofing.

In addition, the soles of the feet receive the most heat in actual sneakers, and the most sweat glands are distributed on the soles of the feet, which causes the most frequent disease of the feet toes and soles, and the most fatigued by exercise. The place is also by the soles.

In addition, wearing sneakers designed for outdoor use by athletes who play indoor sports (basketball, volleyball, handball, taekwondo, boxing, wrestling, tennis, etc.) will give up the opportunity of another advantage and lead to a decrease in performance. In recent years, the current trend is to differentiate the sneakers that are worn according to the exercise, and the development trend is also in the indoor sneakers.

In particular, in recent years, in developing sneakers according to the characteristics of each exercise, even if the water soaks in the outsole, it maximizes the breathability through the floor to make the soles more comfortable to have better results for the purpose of the athlete. .

For example, the sole 11, midsole 12, insole 13 and upper as shown in the conventional breathable sneaker shown in Fig. 1A (Korean Registered Utility Model No. 0248603 (Registration Date: September 18, 2001)) In the shoe consisting of, the sole 11 is formed with a plurality of vent holes (V) penetrating the inner and outer surfaces of the front portion (F), and is laminated on the inner surface of the sole 11, the edge portion S of a predetermined width A plurality of hemispherical protrusions P are provided in the middle portion M and the rear portion R of the lower surface except for), and the front portion F penetrates through the upper and lower surfaces of the hemispherical protrusion P. And a midsole 12 having insertion protrusions P ′ that can be formed or inserted into the ventilation hole V without a gap, and are stacked on an upper surface of the midsole 12 and have the same outer circumferential shape as the midsole 12. The insole 13 is formed of a plurality of fine ventilation holes H 'penetrating the upper and lower surfaces.

Such a breathable sneaker of the conventional registered utility model No. 0248603 is formed to correspond to a plurality of projections on the sole 11 and the midsole 12 to minimize the inflow of water into the sneakers, the projection of the sole 11 Although it can be inserted completely without a gap into the ventilation hole (V), it is difficult to prevent the inflow of water as well as the structure is complicated, rather there is a problem that the effect of ventilation is reduced.

In addition, Figure 1b is a structural diagram showing the breathable sneakers (Korean Registered Utility Model No. 0278149 (Registration Date: May 30, 2002)) of another conventional embodiment, the sole 11, the midsole 12 and the insole 13 Covered and bonded with the silver wire mesh 15 and the membrane 17 so that fresh air can be circulated at all times in the state of wearing sneakers through the vent hole 16 formed therein, the foreign matter is filtered by the silver wire mesh 15 As the sweat and moisture inside the body are discharged through the membrane 17, the moisture introduced from the outside can be waterproofed by the membrane 17 so that the user can always keep comfortable temperature and humidity even when walking or running for a long time. It is.

Such conventional registered utility model 0278149 requires additional components of the silver wire mesh 15 and the membrane 17, the silver wire mesh 15 and the membrane 17 to the sole 11 and the midsole 12, In addition, the process of covering and bonding between the insole and the upper 14 is additionally required, which not only increases the overall structure and causes cost increase, but also prevents inflow of water by the membrane 17 to some extent. Is extremely deteriorated, there is a problem that can not be practical.

In particular, the sole 11 of the above-mentioned prior art registration Utility Model Nos. 0248603 and 0278149 have many problems in manufacturing since the vents are formed. The reason for this is that the bottom surface of the sole 11 should be formed with various irregularities in order to prevent slipping when grounding with the floor in indoors or outdoors. However, when the ventilation hole is formed, the process of forming the irregularities in the mold method Not only this is difficult, there are many problems, such as the effect of the anti-slip decreases as much as the uneven pattern is not formed in the portion where the ventilation hole is formed.

In addition, the above-mentioned prior art registered Utility Model Nos. 0248603 and 0278149 have a problem that when the user stands still while wearing sneakers, the sole 11 is in close contact with the ground surface so that no ventilation is achieved at all. .

The present invention in order to solve the above problems in the general sneakers consisting of the sole, midsole, insole, upper to form a half-moon-shaped groove so that the outside air inlet tube can be installed on both sides of the midsole, On the inner side, an air passage is connected to the half moon groove, and the air passage supplies air to the inside of the sneaker (especially the sole), thereby maximizing the realization of ventilation, and generating sweat by supplying fresh air. Not only prevents the formation of diseases such as athlete's foot, but also maintains breathability through the side of the midsole even when standing still while wearing sneakers, and absorbs the impact of the user's weight when walking to improve performance. Making a contribution is a technical task.

The present invention is in contact with the ground and having a waterproof function and non-slip function, the upper and the sole surrounding the outside of the foot of the user combined with each other the midsole that functions as a supplement, such as shock absorption, and installed inside the upper In the sneakers comprising an insole in contact with the sole of the, the midsole has a plurality of half-shaped grooves are formed at regular intervals to suck and discharge air on both sides, the bottom of the midsole is a ventilation flow path connected to the groove portion Is formed in the longitudinal direction at regular intervals, a plurality of first through-holes are formed at regular intervals in the ventilation passage, the half-shaped grooves to absorb the shock when the user's weight is transmitted to prevent damage to the midsole A buffer tube is installed to flow in, and the insole has a ball into the sneaker at a position corresponding to the first through hole.

Hereinafter, the configuration of the breathable running shoes according to the present invention will be described with reference to FIGS. 2 to 5 as follows.

First, the breathable sneakers of the present invention are in contact with the ground and has a waterproof function and a non-slip function sole 11, and the upper 14 and the sole 11 surrounding the outside of the foot of the user by combining with each other, such as shock absorption It is composed of a midsole 12 that functions as a complement, and the insole 13 installed inside the upper 14 and in contact with the sole of the human body.

The midsole 12 has a plurality of half moon grooves 21a, 21b formed at regular intervals on both sides thereof, and the grooves 21a, 21b and the bottom surface of the midsole 12, as shown in FIG. Two ventilation passages 22a and 22b are connected in a longitudinal direction at regular intervals, and the plurality of first passages 23a and 23b are formed at regular intervals in the ventilation passages 22a and 22b. It is.

In addition, the half moon-shaped grooves 21a and 21b have a half moon-shaped buffer tube 24a and 24b that absorb shocks and prevent distortion or tearing of the midsole 12 when a user's weight is transmitted. Inflow is installed, the insole 13 has a plurality of air supply to the inside of the sneakers at a position corresponding to the first through holes (23a, 23b) formed in the ventilation passages (22a, 22b) of the midsole 12 The second through holes 13a and 13b are formed and constituted.

Wherein the buffer tube (24a) (24b) is firmly attached so as not to be separated from the midsole (12) using an adhesive when installed in the recessed portion (21a) (21b) of the midsole (12).

Referring to the working relationship of the breathable running shoes of the present invention configured as described above are as follows.

First, when the user stands still while wearing the breathable sneaker 10 of the present invention, the outside air passes through the buffer tubes 24a and 24b installed in the recesses 21a and 21b of the midsole 12. It flows into the side of the sneaker, and the introduced air passes through the ventilation passages 22a and 22b of the midsole 12 and the first through holes 23a and 23b of the midsole 12 and the second through hole of the insole 13. It is delivered to the sole of the user via (13a) (13b).

On the other hand, when the sneaker 10 is in contact with the ground to walk, the midsole 12 is compressed by the user's weight, the humid air is evenly distributed in the upper 14, especially the front of the sole, the second through hole of the insole 13 (13a) (13b) and the first through holes (23a) and (23b) of the midsole 12 exit the ventilation passage (22a) (22b), the humid air flowing through the ventilation passage (22a) (22b) (12) is discharged to the outside through the buffer tube (24a, 24b) provided in the recessed portion (21a) (21b).

On the contrary, when the sneaker 10 is separated from the ground to walk, the midsole 12 is released from compression to form a space portion, so that a difference in air pressure occurs with the outside air rapidly through the buffer tubes 24a and 24b. It flows in and is transmitted to the sole of a user through the 1st through holes 23a and 23b of the midsole 12, and the 2nd through holes 13a and 13b of the insole 13 by this air pressure difference.

As described above, the breathable sneakers of the present invention keep the feet in a comfortable state by supplying to the sole by sucking the outside air and supplying the outside air at the same time as the midsole 12 is pumped by the user's weight when walking or walking. In addition, air is also introduced through the side of the midsole 12 in the on-time state, as well as having a shock absorbing function when walking by the buffer tube (24a, 24b).

In addition, even when water below the height of the sole 11 is accumulated on the ground, water does not flow into the sneaker 10 at all, and no slip is formed at the bottom of the sole 11 so that slippage is prevented. Will not affect the pattern formation at all.

As described above, the present invention forms a half moon-shaped groove so that a tube into which outside air flows in both sides of the midsole may be installed in a conventional sneaker composed of a sole, a midsole, an insole, and an upper, and an inner side of the midsole. There is formed an air passage connected to the half moon groove, and through the air passage to supply air to the inside of the sneakers (especially the sole) to maximize the implementation of ventilation, and to suppress the generation of sweat by supplying fresh air In addition to preventing the formation of diseases such as athlete's foot, even when standing still while wearing sneakers, it maintains breathability through the side of the midsole and can also contribute to improving performance by absorbing the shock of the user's weight when walking. It has an effect.
