Description

Mid-sole for a shoes with impact dispersion and round walking function}

The present invention attaches a hard support pad to the bottom surface of the cushion pad to be a cushioning material, and the support pad has a constant distance from the heel to the rest of the toe except the portion corresponding to the toe through the outer surface of the sole. By making the supportive protrusion protrude, the sole portion of the foot where the walking load mainly acts is more comfortably supported by the cushion pad, while the supporting load allows the walking load to be evenly distributed over the entire surface of the sole. Due to this, the fatigue applied to the sole of the foot can be further reduced, and at the same time, the cushion pad located at the portion where the support bar is not formed is compressed and deformed in an arc shape along the walking path by the walking load, thereby causing the wearer to More comfortable, natural and efficient cloud walking Having a lock function and a shock dispersion cloud walking function relates to a shoe midsole.

In general, shoes are worn to protect the foot of the human body and are manufactured and marketed in a wide variety of shapes and types. However, shoes are usually covered by protecting the soles of the foot and the ankle, and the soles of the foot are protected. It is composed of a shoe sole to increase the frictional force between the and to improve the walking ability, and to mitigate the impact on the sole of the foot during walking.

In the case of the conventional shoes as described above, to absorb the shock transmitted from the ground to the soles when walking, insoles on the inner bottom surface of the shoes or the soles and heel portion of the shoe made of rubber and foam sponge with excellent cushioning In addition, it is known that an elastic restoring body such as an air bag or a spring is incorporated in a shoe sole.

As described above, when manufacturing a shoe sole made of rubber or foam sponge, or when an elastic restoration such as an air bag or a spring is embedded in the shoe sole, only a simple shock absorbing function can be performed. When based on a walking path that comes in contact with the ground while having a schematic arc shape up to now, the conventional general shoe sole has a problem that hardly contributes to the aspect to perform natural and efficient walking.

In particular, with the recent increase in living standards and the spread of five-day workweeks, the number of people who enjoy outdoor activities has increased significantly, thereby making people who enjoy outdoor activities feel a better fit and at the same time Footwear manufacturers are investing a lot of time and effort in the development of functional footwear that prevents excessive stress on the joints and soles of the foot and contributes to health promotion by simply walking and wearing shoes.

As various functions that can be applied to the shoes as described above, the anti-slip function, shock absorption function and athlete's foot prevention and odor removal function according to the ventilation is already being actively applied, and the ball with the shock absorption during walking Functional shoes are also provided that allow for natural and efficient propelled walking (hereinafter referred to as 'cloud walking') as if rolling on a flat surface.

As a functional shoe and a walking propulsion member that can be applied to the cloud as described above, the applicant has been filed as a patent application No. 120288 in 2005 (application date: December 09, 2005) and patented No. 10-560367 BACKGROUND ART A registered walking propulsion member and a shoe incorporating the walking propulsion member are known (registered date: March 07, 2006).

The walking propulsion member previously filed by the present applicant is provided with upper and lower bodies in a shoe heel shape, and partition walls are installed at regular intervals between the upper and lower bodies, and the partition walls are formed of the upper and lower bodies. A first bulkhead formed vertically at a point of 5 to 4/5, and an inclination increases as the distance from both sides of the reference bulkhead increases to 16 to 20 degrees at both ends of the upper and lower bodies; The second compression partition is made.

Therefore, when a predetermined pressure is applied through the pre- filed walking propulsion member, the compression ratio becomes high at one end of the walking propulsion member, and the compression ratio decreases toward the middle portion of the walking propulsion member, and at the middle portion of the walking propulsion member. Compression ratio is increased again toward the other end portion, and thus the outer shape of the walking propulsion member is bent in an arc shape as a whole.

If the above-described propelled walking propulsion member is embedded in the heel portion of the shoe sole or if the walking propulsion member itself is installed with the heel, the walking propulsion member elected by the load of the body sequentially acting along the heel when the wearer walks It is compressed to a curved shape suitable for rolling walks, and as a result, it is possible to achieve the joint protection of the pedestrian's knees and feet and to reduce the fatigue of the foot through natural and efficient walking as well as absorbing shocks when walking.

However, since the pre-registered walking propulsion member is applied only to the heel portion of the shoe sole, it was able to achieve a short-term cloud walking at the initial point of walking when the heel touches the ground, ), There was a lack in terms of providing continuous rolling gait while properly distributing the load applied to the sole over walking and end of walking from the toe (heel).

As a result, more rational and efficient load distribution and cloud walking cannot be achieved over the entire length of the foot when the wearer walks, so that the joint protection of the knee and the foot of the pedestrian and the fatigue relief effect of the foot are somewhat reduced. In the case of the propelled walking propulsion member, like the airbag or the spring, it is manufactured as a separate part from the sole and built in the sole of the shoe, thereby increasing the manufacturing cost of the shoe due to the cumbersome process according to the manufacture of the shoe sole. It was also a factor.

The present invention has been devised to solve the problems of the prior art and the prior application, the shoe sole having a shock dispersion function and the cloud walking function according to the present invention is hard (바닥) of the bottom surface of the cushion pad is a cushion material A support pad is attached to the support pad so that the support pads are protruded at regular intervals from the heel to the rest of the toe, except for the part corresponding to the toe. The pads allow for more comfortable support, while the support bars allow the walking load to be evenly distributed over the entire surface of the sole, thereby further reducing the fatigue applied to the sole during walking. Let it be technical problem.

In addition, the present invention, when the walking load acts along the cushion pad located in the portion where the support is not formed, the compression rate of the cushion pad is lowered toward the middle foot portion, the compression rate of the cushion pad is increased toward the heel and toe portion By adjusting the arrangement of the supporters so that the cushion pads located in the areas where the supporters are not formed are bent in a curved shape along the length of the sole along the walking path, which makes the shoes wearer more comfortable. Another technical challenge is to make the joints of the ankles and knees safer by performing a more natural and efficient cloud walking.

Finally, the present invention allows the support pad forming the sole of the shoe can be directly applied to the outsole (sole, outsole), only by adhering the cushion pad and the support pad molded into the required shape It is another technical task to contribute to the aspect of reducing the manufacturing cost of functional footwear by improving the productivity of functional footwear, thereby allowing the manufacture of shoe soles capable of rolling clouds.

The present invention as a means for solving the above technical problem, in the shoe midsole is applied to the shoe sole to support the walking load, the shoe sole is made of a cushion pad and a support pad to be the bottom plate, the support The support surface protrudes at regular intervals on the upper surface of the pad, and the portion of the upper surface of the support pad from the heel to the outer surface of the sole and the toe of the foot becomes a flat portion without the support skin being formed, and the flat portion is the sole of the foot. The area is increased toward the heel and tiptoe portion of the middle arch portion of the, and the lower side of the cushion pad is characterized in that the insertion groove corresponding to the support bar of the support pad is formed, the support pad Is characterized in that the sole for a shoe sole.

According to the present invention as described above, by preventing the support to be located in the lower part of the sole where the load at the time of walking from the heel of the wearer to the toe portion through the lateral surface of the sole of the foot is not concentrated, the sole portion of the sole is cushion pad By being more comfortable to support by, while supporting the foot to distribute the walking load evenly over the entire surface of the sole, thereby reducing the fatigue applied to the sole when walking.

In addition, by reasonably adjusting the support structure of the support pad formed on the support pad and the resulting cushion pad support for each foot part, the cushion pad located at the portion where the support bar is not formed is compressed and deformed in a circular arc shape along the walking path. This makes it possible for people who wear shoes to perform more natural and efficient propulsion rolling walks, which makes the wearer's knee and ankle joints more secure. Of course, just walking and wearing the shoe to which the shoe midsole of the present invention is effective to contribute to the health of the wearer.

In addition, since the support pad constituting the shoe sole of the present invention can be applied to the outsole (out-sole), the cushion pad and the support pad are formed in the required shape, and then simply adhered to the cloud. There is an effect to easily manufacture a functional shoe sole that can walk, thereby improving the productivity of the functional shoe has the effect of contributing to the aspect of reducing the manufacturing cost of the functional shoe.

Hereinafter, described in detail with reference to the accompanying drawings, the present invention for achieving the above object is as follows.

Shoe sole 10 according to the present invention, as shown in Figures 1 to 3, respectively, cushion pad 11 to be a cushion material, and to support the cushion pad 11 in the lower portion of the cushion pad 11 The cushion pad 11 is made of a support pad 12 as a bottom plate, and the cushion pad 11 is a material applied to a normal shoe sole and is made of a material having excellent elasticity such as natural rubber, synthetic rubber or polyurethane foam, and the support pad ( 12) may be made of a hard synthetic resin material having superior rigidity than the cushion pad (11).

Bars 14 protrude from the upper surface of the support pads 12 at regular intervals, and the support bars 14 compress the cushion pads 11 when a walking load acts on the cushion pads 11. As the function of controlling the amount of deformation, by adjusting the position of the support body 14 is formed, that is, the structure of the support structure 14 so that the compression degree of the cushion pad 11 is expressed differently for each sole area. It becomes possible.

In other words, the compression deformation of the cushion pad 11 due to the walking load is reduced in the portion where the support bar 14 is formed, whereas the cushion pad 11 due to the walking load in the part where the support bar 14 is not formed. The compressive strain of is that large, and in the drawing from the heel to the toe through the lateral surface of the sole of the foot to the support 14 is not formed on the support pad 12.

Therefore, the corresponding portion is formed by the flat portion 15 by only the support pad 12, the flat portion 15 is the heel and the center of the sole of the foot (concave in the center of the sole) In order to gradually increase the area toward the tiptoe, that is, the interval where the support 14 is not formed is gradually widened, and the area ratio occupied by the flat portion 15 is shown in Table 1.

Table 1: Area ratio of the flat part according to the plantar part

Sole (support pad) Toe (heel) Footbow Heels 1/3 1/3 1/3 1/2 1/2 50-80% 30-50% 10-30% 0-10% 20-50% 50-80%

As described above, the area ratio occupied by the flat portion 15 is based on the planar cross-sectional area of the support pad 12. In Table 1, the area of the toe portion is divided into three portions, and the area of the heel portion is divided into two portions. The reason why it is divided into, is because the toe of the human foot is longer than the toe side of the foot relative to the foot, so that the reference area divided by each area to be similar to each other.

However, the example applied in Table 1 is only one representative embodiment, it is to be understood that the present invention is not limited within the range of the numerical values shown in Table 1, the material of the sole 10 Considering the material and elasticity of the cushion pad 11 and the thickness of each foot part, the area in which the flat portion 15 is formed can be found to be arbitrarily adjusted by the manufacturer.

As shown in FIGS. 2 and 3, the insertion groove 13 is formed at a position corresponding to the support teeth 14 of the support pad 12 on the lower side of the cushion pad 11. When the cushion pad 11 and the support pad 12 are integrally attached to each other, the support bars 14 may be easily inserted through the insertion grooves 13 of the cushion pad 11.

When the support pad 12 is based on the thickness of the cushion pad 11, the support pad 12 is preferably about 1/5 to 1/2 in terms of properly adjusting the overall thickness of the shoe sole, and the support When the height of the flesh 14 (= depth of the insertion groove) is based on the thickness of the cushion pad 11, it is about 4/5 ~ 1/2 is the most suitable level for rolling walk.

In addition, the interval between the support 14 is formed may vary depending on the size of the shoe sole, it is most preferable to be within the range of at least 0.3mm to a maximum of 1cm, each support 14 is less than 0.3mm If there is a gap, the molding work of the support pad 12 becomes somewhat difficult, and if each support 14 is formed at an interval exceeding 1 cm, the amount of compression deformation of the cushion pad 11 by the support 14 This is because the adjustment function may be degraded.

As described above, the flat portion 15, in which the support body 14 is not formed, corresponds to the portion of the sole where the actual walking load acts when the person wearing the shoe walks, that is, the walking load path P in FIG. By not forming the support ribs 14 on the sole portion, the sole portion is more comfortably supported by the cushion pad 11.

In addition, assuming that a uniform distribution load is applied over the entire sole surface, the cushion pad 11 corresponding to the flat portion 15 is compressed more and the cushion corresponding to the portion where the support ribs 14 are formed. Since the pad 11 is compressed less, this causes the foot portion where the walking load is not concentrated to additionally support the walking load by the support body 14, thereby reducing the walking load applied to the sole. More evenly distributed support.

As described above, the sole portion where the walking load is intensively acts more comfortably by the cushion pad 11, and the sole portion other than the sole portion where the walking load is intensively acts on the support body 14. As the walking load can be more evenly distributed and supported, the fatigue applied to the sole of the walking can be further reduced.

In particular, the area where the flat portion 15 is formed, that is, the area of the cushion pad 11 located at the portion where the support ribs 14 are not formed, gradually increases toward the heel and toe side of the sole of the sole of the foot. Since the walking load acts along the walking load path P shown in FIG. 2, the compressive deformation of the cushion pad 11 is reduced by the support bars 14 in the middle soup part, and the heel and the toe As the compression strain of the cushion pad 11 gradually increases.

Therefore, the amount of deformation of the cushion pad 11 along the walking load path P is approximately large → medium → small → medium → large → large. Deformation diagram of (11) is formed in a circular arc (적합한) shape suitable for the propelled rolling walk along the walking load path (P) corresponding to the full length of the sole, thereby the shoes to which the sole 10 of the present invention is applied When worn and walking, more natural, efficient and stable rolling can be performed.

In addition, similar to the partition wall of the pre- filed walking propulsion member, the support ribs 14 are formed in the vertical direction with respect to the cushion pad 11 at the midfoot arch or a position adjacent thereto, and at the portions corresponding to the heel and the toe When the support body 14 is formed to be inclined with the cushion pad 11 at an angle of about 16 to 20 degrees toward the outside direction, there is an advantage that more preferable propulsion rolling can be enabled.

Finally, in the shoe sole 10 according to the present invention, the support pad 12 is made of a hard synthetic resin material with excellent rigidity than the cushion pad 11, which is an outsole applied to the existing shoe sole (Outsole: Means that the support pad 12 can also perform the function of the out-sole, thereby allowing the support pad 12 can be easily applied as a sole for a shoe sole.

When the support pad 12 is applied to the sole of the shoe sole as described above, the cushion pad 11 and the support pad 12 are formed in the required shape, and then simply walked together, the cloud walking is performed. It is possible to easily manufacture a functional shoe sole as possible, thereby improving the productivity of the functional shoe can also contribute to reducing the manufacturing cost of the functional shoe.

In addition, when the support pad 12 is applied as a shoe sole, it is preferable that the lower side of the support pad 12 be a non-slip surface for preventing slip, and the cushion pad 11 ) And the upper of the cushion pad 11 along the outer surface of the support pad 12 so that the support pad 12, which becomes the sole, can be easily sewn together with the upper for shoes. It is preferable to form the rim for sewing.
