Description

Sole {SHOE SOLE}

The present invention relates to a shoe sole formed on the bottom of a shoe, such as shoes, sneakers, etc. More specifically, by forming a shoe sole using a memory foam having excellent elasticity and resilience function for a comfortable fit when wearing shoes, The present invention relates to a shoe sole capable of uniformly dispersing the applied pressure to reduce the fatigue of the foot along with the shock absorbing effect of walking, thereby maintaining a comfortable wearing condition.

Its high density but low elasticity can absorb more than 95% of the strongest impacts.

In general, the foot is connected to 60 or so reflexes and 7,000 reflexes, which are distributed on the soles of the body, so that it is important to be called the 'second heart'.

The foot, which is responsible for such important functions of the human body, wears shoes such as shoes or sneakers to protect from the outside during walking, and these shoes are mostly worn on the lower part of the shoes to absorb a comfortable fit of the foot and the shock applied during walking. A shoe sole made of various materials is formed.

That is, in the conventional shoe sole has a predetermined cushioning function in order to make the wearer's feet more comfortable, such a shoe sole has a variety of materials and shapes, such as a fabric made of the same shape as the sole of the shoe The midsole consisting of an upper pad and a lower pad formed of a cushion member such as a sponge having the same shape on the lower surface of the upper pad is bonded to the sole, and the wearer is softened by the softness of the upper pad of the midsole and the cushion of the lower pad. You can relax your feet to some extent.

In some cases, a thin insole may be provided on the upper portion of the midsole so as to be in direct contact with the wearer's foot, or the insole may be provided to be separated or fixed from the midsole.

However, in such a conventional shoe sole, when the wearing period of the shoe has elapsed for a certain degree or more, a portion of the sole to which the wearer's load is concentrated is squeezed, and the compressed portion is no longer restored.

As a result, the function of the midsole for comforting the wearer's foot cannot be properly exhibited, so that the wearer becomes in the same state as wearing the shoe without the midsole, thereby increasing the fatigue of the foot, thereby not benefiting the wearer's health.

In addition, the shoe covering the foot of the wearer except the sole is made of leather or polypropylene material corresponding to the shape of the foot, it is difficult to discharge the sweat or water generated from the foot, from this fungus, eczema It maintains the proper temperature and water for the bacteria and athlete's foot.

Therefore, when the shoes are worn for a long time, the inside of the shoes is not ventilated, and the inside of the shoes is sweaty and smells and the moisture adversely affects the health of the feet.

The present invention is to solve the above problems, by forming a memory foam having excellent elasticity and recovery function in the sole, by absorbing the impact of walking by uniformly dispersing the pressure applied to the sole by the walking load when wearing shoes The purpose is to provide a shoe sole that can reduce the fatigue of the foot by having a comfortable fit.

In addition, by having a structure that can circulate the air inside the shoe in the shoe sole formed with a memory foam, keeps the inside of the shoe comfortable and clean to prevent the occurrence of odor and to suppress the growth of various bacteria, as well as the foot hygiene state The purpose is to provide a shoe sole that can improve health.

Technical concept of the present invention for achieving the above object, is formed on the sole 110 of the shoe, the upper surface of the sole 110 of the shoe, and has the same shape as the sole 110 of the shoe Including a midsole 120 consisting of an upper pad 122 and a lower pad 124, the lower pad 124 is achieved by a shoe sole characterized in that formed of a memory foam.

Here, a first elastic piece 112a inclined upward is formed on an upper surface of the sole contacting the lower pad 124 of the midsole 120, and a second elastic piece (corresponding to the first elastic piece 112a) is formed. It is preferable that 124a is formed on the lower pad 124 so that the first elastic piece 112a and the second elastic piece 124a match.

In addition, the first elastic piece 112a and the second elastic piece 124a formed in the sole 110 and the lower pad 124 are cut in a “b” shape on each surface thereof, and the first elastic piece ( It is preferable that 112a) and the 2nd elastic piece 124a join each other.

In addition, the first elastic piece 112a and the second elastic piece 124a formed in the sole 110 and the lower pad 124 are protruded to be inclined at their respective surfaces, and each protruding first elastic piece is formed. Fixing grooves 112c and 124c are preferably formed in each of the sole 110 and the lower pad 124 so that the front ends of the 112a and the second elastic pieces 124a are inserted into and fixed to the mating surface.

In addition, the midsole 120 preferably includes a vent hole 121 penetrating the upper pad 122 and the lower pad 124.

The sole according to the present invention, the lower pad of the midsole is formed of a memory foam excellent in elasticity and recovery function, the midsole and the sole is bonded by a plurality of elastic pieces, thereby the pressure applied to the sole by the walking load when wearing shoes It is possible to reduce the fatigue of the foot by uniformly dispersed in the memory foam and elastic pieces to absorb the impact of walking and to have a comfortable fit.

In addition, by forming an empty space between the midsole and the sole, by repeating the operation of the midsole and the sole is in contact with each other or falling due to the walking load, thereby smoothing the flow of air between the midsole and the sole outsole Can be made comfortable, thereby improving the health of the wearer as well as the hygiene of the foot.

The terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary meanings and the inventor may properly define the concept of the term to describe its design in the best possible way It must be construed as a meaning and a concept consistent with the technical idea of the present invention based on the principle.

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

1 is a perspective view showing a shoe sole according to the present invention, Figure 2 is an exploded perspective view showing the midsole and the sole of the sole according to the present invention. Referring to the drawings, a shoe sole made of various materials is formed at the bottom of a shoe such as shoes or sneakers. In other words, the sole 100 according to the present invention is largely composed of a sole 110 formed in the lower portion of the shoe and in direct contact with the ground, and a midsole 120 formed in the upper portion of the sole 110. .

The midsole 120 includes an upper pad 122, such as a fabric having the same shape as the sole 110, and a lower pad 124 having the same shape on the lower surface of the upper pad 122.

In particular, the lower pad 124 according to the present invention is preferably formed of a memory foam, to evenly distribute the pressure applied to the sole by the walking load to absorb the impact of walking and to have a comfortable fit This can reduce foot fatigue.

The memory foam forming the lower pad 124 of the midsole 120 is a kind of sponge that was developed as part of a NASA space program in the 1960s. These foams were developed to mitigate the tremendous shocks and vibrations that astronauts have on the spine and neck due to the gravity of the spacecraft when it leaves the atmosphere. Polyurethane-based foams are extremely sensitive to heat and pressure, resulting in excellent body pressure. Distributed function In other words, the memory foam has a high density but low elasticity and has a physical property capable of absorbing 95% or more of strong impacts.

These memory foams have been proven to maintain resilience even when subjected to 125,000 impacts, divided by 16 times, with a weight of about 110Kg, and are soft materials that do not press the body.

As the above-described memory foam is formed on the lower pad 124 forming the midsole 120, as described above, the pressure applied to the sole by the walking load is uniformly distributed to absorb the shock caused by walking and to provide a comfortable fit. This can reduce the fatigue of the foot.

As such, the midsole 120 in which the memory foam is formed may be bonded over the entire area of the upper surface of the sole 110, but in some cases, the first elastic piece may be attached to each of the midsole 120 and the sole 110. The sole 100 is formed by forming the second elastic piece 124a and 112a and fixing the midsole 120 and the sole 110 by the first elastic piece 112a and the second elastic piece 124a. By improving the elasticity of the better shock absorption can be exerted, and by circulating the air inside the shoe to make the interior of the shoe comfortable, as well as using a small amount of adhesive, it will be possible to reduce the shoe manufacturing cost. This will be described with reference to Figs. 3A to 4B.

3A and 3B are cross-sectional views showing elastic pieces formed on each of the midsole and the sole of the shoe sole according to the present invention. Referring to the drawings, the upper surface of the sole 110 and the lower surface of the midsole 120 facing the sole 110 and the midsole 120, respectively, the first elastic piece 112a and the second elastic A large number of pieces 124a are formed.

That is, the first elastic piece 112a having a predetermined length and inclined upward is formed on the upper surface of the sole 110, and corresponds to the first elastic piece 112a on the lower surface of the midsole 120. The second elastic piece 124a having a predetermined length to be inclined downward is formed, and the first elastic piece 112a and the second elastic piece 124a are joined as shown in FIG. 3A.

In this case, the first elastic piece (112a) and the second elastic piece (124a) is formed by cutting in a "b" shape on each surface, respectively, the first elastic piece (112a) and the second elastic piece (124a) The receiving grooves 112b and 124b are formed in the grooves.

As described above, the first elastic piece 112a and the second elastic piece 124a are formed on the upper surface of the sole 110 and the lower surface of the midsole 120, respectively, and the first elastic piece 112a and the second elastic piece 112a are formed. By bonding the elastic pieces 124a so as not to fall, an empty space is formed between the sole 110 and the midsole 120.

As such, the empty space formed between the sole 110 and the midsole 120 not only serves as a passage through which air in the shoe can be circulated, but also by the respective elastic pieces 112a and 124a joined together. By improving the resilience, better shock absorption can be exerted.

That is, as shown in FIG. 3B, when a shoe is worn, a load of the wearer is applied to the upper surface of the midsole 120, whereby the first elastic piece 112a and the second elastic piece 124a joined to each other are attached. The first elastic piece 112a and the second elastic piece 124a are inclined to be received in the respective receiving grooves 112b and 124b.

At this time, when the inclined first elastic piece 112a and the second elastic piece 124a are laid down to be received in the respective receiving grooves 112b and 124b, the first elastic piece 112a and the second elastic piece 124a are laid down. As the inherent elastic force of) is exerted, the shock due to the walking load is primarily absorbed.

As such, when the first elastic piece 112a and the second elastic piece 124a are accommodated in each of the receiving grooves 112b and 124b, the empty spaces of the sole 110 and the midsole 120 are reduced and the midsole 120 is reduced. In other words, while the lower surface of the lower pad 124 formed of the memory foam and the upper surface of the sole 110 are in contact with each other, the pressure applied to the sole by the walking load is uniformly dispersed in the memory foam to the walking It will absorb the impact.

In particular, when the stepper to which the walking load of the wearer is transmitted falls from the ground, the midsole 120 and the sole 110 that are in contact with each other by the elasticity of the first elastic piece 112a and the second elastic piece 124a are dropped, and thus the midsole ( An empty space is formed between the sole 120 and the sole 110, and when the stepping foot is separated from the ground and re-contacts with the ground to apply a walking load, the midsole 120 and the sole 110 are repeatedly contacted with each other. By circulating the air of the shoe makes the interior of the shoe a pleasant state.

On the other hand, the first elastic piece 112a and the second elastic piece 124a formed in the sole 110 and the midsole 120 are fixed to each other without being bonded to each other, or use a small amount of adhesive by reducing the adhesion area to a minimum. By doing so, it may be possible to reduce shoe manufacturing costs. This will be described with reference to FIGS. 4A and 4B.

4a and 4b is a cross-sectional view showing another embodiment of the elastic piece formed in each of the midsole and the sole of the shoe sole according to the present invention. Referring to the drawings, each of the upper surface of the sole 110 facing the sole 110 and the midsole 120 and the lower surface of the midsole 120 have a predetermined length and are inclined first elastic pieces. 112a and the second elastic piece 124a are formed to protrude, so that the protruding ends of the first elastic piece 112a and the second elastic piece 124a are inserted into and fixed to the mating surface. Fixing grooves 112c and 124c are formed in the pads 124, respectively.

Thus, the front ends of the first elastic piece 112a and the second elastic piece 124a are inserted into and fixed to the fixing grooves 112c and 124c formed in the sole 110 and the lower pad 124, respectively. This does not arbitrarily separate from the sole 110.

To this end, the tips of the fixing grooves 112c, 124c, the first elastic piece 112a and the second elastic piece 124a may have a coupling structure such as a hook, and in some cases, the first elastic piece An adhesive is applied from the tip of the first elastic piece 112a and the second elastic piece 124a so that the tip of the piece 112a and the second elastic piece 124a and the fixing grooves 112c and 124c can be closely joined. After applying to the fixing grooves (112c) (124c) may be adhesively fixed.

As described above, the first elastic piece 112a and the second elastic piece 124a are formed on the upper surface of the sole 110 and the lower surface of the midsole 120, respectively, and the first elastic piece 112a and the second elastic piece 112a are formed. As the elastic piece 124a is fixed to the mating fixing grooves 112c and 124c, an empty space is formed between the sole 110 and the midsole 120, from which a passage through which air in the shoe can be circulated. Not only serves to improve the elasticity of the sole by each elastic piece bonded can be exerted more excellent shock absorption.

In addition, a plurality of first elastic pieces 112a and second elastic pieces 124a are formed on the lower pad 124 and the sole 110 of the midsole 120 formed of the memory foam as described above. By forming an empty space between the sole 110 and the midsole 120 by the 112a and 124a, the air in the shoe may be more effectively circulated when the air in the shoe is circulated. This will be described with reference to FIG.

5 is a cross-sectional view showing a vent hole formed in the midsole of a shoe sole according to the present invention. Referring to the drawings, the first elastic piece 112a and the second elastic piece 124a are formed on the upper surface of the sole 110 and the lower surface of the lower pad 124 of the midsole 120 formed of the memory foam, respectively. By bonding, the empty space is formed between the sole 110 and the midsole 120, the air of the empty space between the sole 110 and the midsole 120 smoothly to the upper portion of the midsole 120 A vent hole 121 penetrating the upper pad 122 and the lower pad 124 is formed in the midsole 120 to exhaust or intake air.

As the vent hole 121 is formed in the midsole 120 as described above, the midsole 120 and the sole 110 contact with each other or fall off due to a walking load, and thus the midsole 120 and the bottom are repeated. The volume of the empty space between the windows 110 is repeatedly decreased and increased to exhaust or intake air between the midsole 120 and the sole 110 through the air vents.

Thus, by smoothing the flow of air between the midsole 120 and the sole 110 can be comfortable inside the shoe, thereby improving the health of the wearer as well as the health of the foot.
