Description

Shoes made of the outsole with air holes}

The present invention relates to a shoe using a shoe sole provided with a plurality of vents, in more detail in the shoe sole which is in contact with the ground, forming a plurality of vents penetrating through the shoe sole, the interior window laminated on the inner surface of the shoe sole in the shoe The middle structure of a synthetic resin material, such as TPR (Thomo Plastic Rubber) formed with a plurality of protrusions and through holes on the bottom thereof, has a triple structure in which a waterproof nonwoven fabric and an insole are sequentially stacked, and the valley between the protrusions and the protrusions of the bottom of the TIPI midsole The present invention relates to a shoe provided with a shoe sole vent for providing a ventilation function inside the shoe to be a passage of air flowing into and out of the vent and at the same time obtaining a cushioning effect by the protrusion.

In the early years, shoes developed as people walked simply played a role of protecting the feet from being uncomfortable and injured.However, with the improvement of living standards and the development of shoe manufacturing technology, walking, mountain, orthodontic, and specific Shoes have been used depending on the purpose of exercise.

In particular, as the importance of health has emerged, sports shoes have made rapid progress, and new materials and structures have been continuously developed.

However, unlike slippers or sandals, shoes have a common weakness regardless of their purpose, which is a problem of breathability.

Since shoes are made to fulfill the basic purpose of walking and protecting the foot, the space inside the shoe that covers the foot is sealed except for a certain part of the upper part where the shoe can be taken off. .

Therefore, when the shoes are worn, the inside of the closed shoes can not be properly ventilated, and a lot of sweat is generated in the feet, which promotes a warm and humid environment that allows various bacteria to grow inside and inside the shoes. By causing the odor from the inside of the shoe and the foot, not only causes discomfort, but also causes problems such as skin diseases such as athlete's foot.

The shoes are joined without gaps along the rim of the sole where the upper is in contact with the ground, except where the shoes are worn and taken off, and the interior windows are stacked on the inner surface of the sole to prevent direct contact between the inner surface of the sole and the foot. As a structure, in order to alleviate the odor or athlete's foot of the foot as described above, the interior window may be manufactured from a material containing a specific substance or component such as activated carbon or green tea component, but such interior window is less effective with time. Has a problem.

Similar to the above, Korean Utility Model Publication No. 91-14959 has a breathable bag packed with a dehumidifying agent and an air freshener to remove moisture from shoes caused by sweat and prevent odors between midsole and insole. Although one sole has been disclosed, this does not make its own breathable improvement in the shoe, but it is inconvenient to continuously replace the material by using only a third material to improve the atmosphere in the shoe.

Therefore, methods have been developed to directly improve the breathability inside the shoe rather than by the third material, and the representative one is provided with one or two small diameter vents at specific positions of the outer skin corresponding to the central portion of the side of the foot. In order to improve the breathability in the shoe by the direct inflow of air, the effect was insignificant.

In addition, Korean Patent Publication No. 2000-015884 discloses a forced ventilation shoe having a structure in which a sole is formed with a protrusion on an inner surface and a through hole and a midsole having a protrusion is laminated on a lower surface thereof, which is a protrusion of the midsole. By forming the air layer between the midsole and the sole, so that the through-hole of the midsole is located in the upper part spaced apart from the protrusion on the inner surface of the sole, after the midsole is pressed by the weight of the person, the upper part of the protrusion inside the sole of the sole can be separated While the air of the air layer is inserted through the through hole to the outside of the air layer to obtain a cushioning effect due to the ventilation inside the shoe and the compression and restoring force of the air layer, but also in the shoe by the direct inflow of outside air There is no improvement in breathability.

In addition, Korean Utility Model Publication No. 96-3725 discloses a ventilated shoe sole formed with a plurality of vents and protrusions passing through the side surface of the sole to the upper surface of the shoe sole, which may be introduced through the vent of the side. There is a lack of means for water, and the protrusions come into direct contact with the sole, so that the effect of acupressure can be seen, but there is a problem that is not appropriate to wear for a long time.

In particular, in the case of athletic shoes, the problem of shoe internal ventilation by the violent movement of the foot is more important, a variety of methods for improving ventilation in addition to the conventional methods for improving the ventilation has been developed.

As most of them have been described above, a method of forming air flow paths on the lower surface of the midsole of the flexible material and allowing the air between the sole and the midsole to be circulated by the pump-type compression force that is repeatedly pressed by the weight of the foot. However, these methods have a problem that the ventilation function inside the shoe is restricted and its efficiency is lowered because direct external air intake is not made.

And these days, modern people who are busy have a tendency to exercise indoors, also called health, rather than outdoor exercise, which takes some time to exercise for health, but shoes have no distinction between indoor and outdoor. That is, in the case of indoor exercise shoes, since the floor is used in a dry place, a more substantial ventilation structure can be taken, but conventional shoes have no distinction between indoor and outdoor.

In addition, in the case of outdoor sports in most dry place it is necessary to focus more on ventilation than waterproof structure.

The present invention is to solve the various problems of the conventional shoe having a problem in the ventilation of the shoe room, to form a plurality of vent holes penetrating the upper and lower surfaces of the sole of the sole corresponding to the front of the sole of the sole, By forming a plurality of protrusions on the lower surface of the midsole laminated on the inner surface to allow the outside air to flow directly into the shoe according to the movement of the foot, improve the breathability inside the shoe to minimize the occurrence of foot odor or athlete's foot It is an object of the present invention to provide a more suitable and hygienic shoe.

In addition, there is another object of the present invention to provide a shoe suitable for outdoor sports by additionally adding a waterproof non-woven fabric on the inner surface of the shoe and the upper surface of the upper middle.

The object of the present invention is a shoe sole formed with a plurality of ventilation openings penetrating the outer surface and the inner surface of the shoe that is in contact with the ground, and a plurality of hemispherical protrusions are formed on the inner surface of the sole and the upper and lower surfaces between the projections A midsole provided with a through hole therethrough and a breathable insole stacked on the upper surface of the midsole.

The shoe provided with a shoe sole vent of the present invention has a technical feature that a plurality of vent holes directly penetrating the inner and outer surfaces of the shoe sole is formed in the bottom portion, and the midsole is laminated to the inner surface of the sole where the vent is formed, but is formed on the bottom of the midsole. The tip end of the projection comes into contact with the inner surface of the sole, and an air flow path due to the projection is formed between the inner surface of the sole and the lower surface of the midsole.

Therefore, the outside air introduced through the vent of the shoe sole is circulated through two paths. That is, one is to move to the inner wall of the upper of the shoe, which is the outer peripheral end side of the midsole through the air flow path between the projections and flows into the shoe, and the other is to immediately pass through the through hole of the midsole and the breathable insole It will flow into.

That is, a shoe provided with a shoe sole vent of the present invention has a technical feature that the inflow and outflow of air is efficiently carried out through the upper inner wall side and the central part, ie, the entire bottom of the shoe, which is a specific part of the shoe.

And, the material of the midsole is made of a synthetic resin material having excellent elasticity, such as TI TI, so that the projection formed on the lower surface of the midsole causes elastic deformation against external pressure, thereby giving a cushion-like cushion effect.

However, the shoe of the present invention, because the vent provided in the sole is limited to use on the water floor, it can change the projection formed on the lower surface of the midsole to prevent this, It is also desirable to additionally couple the waterproof nonwoven fabric to the.

The details of the purpose and technical constitution according to the present invention, including the effect thereof, will be clearly understood by the following description with reference to the drawings showing preferred embodiments of the present invention.

Figure 1 is a perspective view of one embodiment of a shoe sole constituting the present invention shoe, Figure 2 is a top and bottom plan view of one embodiment midsole, Figure 3 is a top plan view of another embodiment midsole, Figure 4 is an embodiment insole Top view of the, Figure 5 shows a longitudinal cross-sectional view and a cross-sectional view of the sole and midsole and insole in one embodiment.

As shown, the bottom of the front portion (F) of the sole 11, except for the middle portion (M) and the rear portion (R) corresponding to the arch and heel of the foot, a plurality of vents (V) penetrating the inner and outer surfaces of the sole ) Is formed, the lower surface of the midsole 12 is provided with a plurality of hemispherical protrusions (P) having a diameter smaller than the diameter of the vent hole (V) on the entire surface except the edge portion (S) of a predetermined width, A plurality of through-holes (H) penetrating the upper surface and the lower surface of the () is formed in the bottom of the front portion (F), the insole 13 having the same outer circumference shape as the midsole 12 is fine to penetrate the upper and lower surfaces A plurality of vent holes (H ') are formed.

Therefore, when the midsole 12 and the insole 13 are laminated on the inner surface of the sole 11, an air layer A is formed between the lower surface of the midsole and the inner surface of the sole by the projections P on the lower surface of the midsole, and the midsole. The edge portion (S) of the shoe is also spaced apart from the inner surface of the sole is a movement path to send the air introduced into the vent (V) of the sole to the inner wall side of the upper (not shown).

The diameter of the protrusion P is smaller than the diameter of the vent port V, so that the protrusion P can move freely from the outside of the vent port V to the inside thereof, whereby the inflow and outflow of air is further increased. This is to make it efficient.

At this time, the vent hole (V) of the shoe sole is a passage through which water can flow directly into the shoe when there is water on the bottom. That is, since the water of the bottom can immediately flow into the shoe interior through the vent hole (V) of the shoe sole and the through hole (H) of the midsole, as shown in FIG. 3 to prevent this, the lower surface of the midsole (F) The same number of hemispherical inserts having the same formation pattern as the ventilation holes V are formed on the lower surface of the midsole corresponding to the position of the ventilation holes V of the sole so that the protrusions formed on the sole are completely inserted into the ventilation holes V of the sole without gaps. While forming alternately with the projections (P '), in this case do not form the through hole (H). At this time, the diameter of the insertion projection (P ') is larger than the original projection (P).

Further, in order to more surely prevent water from flowing into the shoe, it is also preferable to additionally couple the waterproof nonwoven fabric to the upper and lower surfaces of the midsole in which the insertion protrusion is formed.

6 is a plan view of the bottom surface of the midsole in which the waterproof nonwoven fabric is bonded, and FIG. 7 is a longitudinal cross-sectional view of the midsole and the insole in which the shoe sole and the waterproof nonwoven fabric are coupled.

As shown, the same protrusions P as the midsole 12 are formed in the middle portion M and the rear portion B of the lower surface except for the edge portion S of the midsole 12, but the front portion ( F) is a waterproof non-woven fabric (12 'A) that covers the front portion (F) of the sole is attached to the surface except for the insertion projection (P') formed so that it can be inserted into the vent (V) of the sole without a gap, the upper surface This waterproof nonwoven fabric 12'A is also attached to the whole.

In addition, the thickness of the waterproof nonwoven fabric 12'A should be approximately equal to the height of the projection P formed on the middle portion M and the rear portion R of the midsole, but not to be small. This is because when the height of the protrusion P is greater, the waterproof nonwoven fabric 12'A may be spaced apart from the inner surface of the sole by the protrusion, and the waterproofing nonwoven fabric 12'A is also inserted into the sole. Its height should be determined so that it can be inserted without any gaps in the ventilation holes (V) without falling from the inner surface.

As another example, the waterproof nonwoven fabric 12'A may be replaced with a metal plate (not shown). Metal plate attachment can be used where there is a risk of serious injuries to the foot, such as military footwear, especially minefields.

At this time, it is more preferable to form a plurality of fine holes through which water, such as air, does not pass through the metal plate.

As described above, a shoe provided with a shoe sole vent of the present invention, because the inside of the shoe is directly ventilated by the outside air introduced through a plurality of vents formed in the sole, high ventilation efficiency to suppress foot odor It is expected to have a significant effect.

In particular, it may be suitable for those who have intense or fast-moving sports shoes or those who have a lot more sweat than ordinary people.
