Description

Functional shoes {Functional shoes}

The present invention relates to a functional shoe, and more particularly, to a functional shoe that can be combined with the shock absorbing system applied to most functional shoes in the shoe sole to improve the functionality and durability.

In general, shoes worn on the feet of the body start with the purpose of preventing direct contact of the foot with the ground, and prevent slippage, alleviate the impact of the foot against the load on the body, and consider the health of the body, including the feet. Has been improved.

Normal shoes have an upper surrounding the foot, an outsole for protecting the sole surface when walking, and a midsole and upper interposed between the upper and the sole to increase the fit by shock absorption. Interposed on the inner bottom surface is composed of an insole (Insole) for giving a more improved fit.

In the case of walking or running with such shoes, the impact from the ground is mainly absorbed from the sole or midsole, and thus, a sole or midsole made of various materials and structures has been developed to give a better shock absorption function. .

The shock absorbing system applied to such shoes mainly includes cushions such as rubber plates or sponges, air tubes using compressed air, and the like. The use of shock absorbing forms has been proposed, but there is a disadvantage in that it cannot be practically used as a shoe due to deterioration of durability of the spring.

As such, as functional footwear companies spread shoes in various ways, various problems occur.

For example, the toe is pushed forward due to the functional shoe cushion, which presents many problems.

First, there is no circulation and foot puffing occurs.

Second, after the blisters due to friction, calluses develop, resulting in toe deformities (valgus valgus, pelvic distortion, etc.).

Third, the joints of the soles of the shoe and the functional parts fall off due to the impact during ignition, or the shoe sole is cracked.

Fourth, there are many cases in which the bottom of the shoe loses stability due to high stability, and the center movement is shaken, causing a lot of bad results when the functional shoe is ignited.

As a result, the conventional functional shoes are not getting a satisfactory response to the customers, the situation is required to improve a lot.

Therefore, the present invention has been devised in view of the above, and by integrally formed in the sole without attaching along the shock buffer system to alleviate the impact when walking, not only can improve the shock absorption performance, but also wear for a long time The purpose is to provide a functional shoe that can also improve the durability of the shoe, such as not falling or cracking.

In addition, the present invention implements an integrated structure of the shoe sole and the impact buffer system, it is possible to reduce the thickness of the sole of the shoe, and accordingly another object to provide a functional shoe that can increase the degree of freedom of shoe design.

In addition, another object of the present invention is to insert the waist strap for maintaining the stiffness of the shoe when the sole injection is made integrally, so that the sole and the waist strap does not move separately, such as to supplement the stiffness of the shoe as well as to extend the life To provide a functional shoe that can be.

Functional footwear provided by the present invention in order to achieve the above object is a functional shoe including a shoe sole, the sole is a constant in the front region and the rear region where the toes and heel touches relative to the arch area that the arch of the sole touches. A plurality of projections having a height is formed integrally with the sole, it is characterized in that it is possible to mitigate the impact when walking by using the cushion function exhibited by the projections.

Here, the protrusion is preferably formed in a cylindrical shape to form an irregular arrangement over the entire area of the front region and the rear region.

In the case of the protrusion formed in the rear region, the protrusion is formed from the bottom in the groove formed in the rear region, and the upper end thereof is positioned higher than the upper surface of the sole of the shoe so that the space is formed around the protrusions when the insole is covered on the protrusions. It is desirable to obtain an air cushion function using compressed air while being formed.

In particular, the functional shoe is a means for maintaining the stiffness of the sole,

And shaped over the arch area and over a portion of the rear region, and features a thrust that is integrally formed by being inserted into the sole injection molding.

Functional shoes provided by the present invention has the following advantages.

First, the shock-absorbing system is not attached separately to the sole of the sole, but is formed integrally when manufacturing the sole, so that the shock absorber can be absorbed better than the existing attachment, and there is no fear of falling or cracking even after a long ignition. In addition, the massage function when walking and has the advantage that noise does not occur.

For example, by integrating the functions (shoe function and shock buffer function) into one without dividing them into two, the three-step walking is advantageous because the floor is not thick when walking, and the sole function does not fall off the joints due to impact. There is an advantage that does not occur.

Second, the thickness of the shoe sole is significantly reduced compared to the functional shoes on the market these days, it is possible to make a good time in terms of design, and also has the advantage that can be safely centered and walking compared to the existing shoes.

Third, the waistband is a shoe sole (urethane, etc.) by bending the waist and the heel together, the shoe sole is firmly compressed during injection, so that the shoe sole and the waist strap is fixed, so that the waist strap and the sole does not move separately.

Fourth, by joining the raw rubber by digging a groove on the outer bottom of the sole, it is possible to walk smoothly three foot (heel-foot-toe) and to extend the life of the shoe.

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

1 to 3 are a perspective view and a cross-sectional view showing a functional shoe according to an embodiment of the present invention.

As shown in Figures 1 to 3, the functional shoe is a shock-absorbing system that alleviates the impact when walking, for example, a shock-absorbing system such as a structure in which a plurality of protrusions are distributed in a predetermined area integrally to the sole. In this way, the shock absorbing performance can be further improved, and the shock-absorbing system can be completely eliminated even if it is worn for a long time, and the soles of the soles can be eliminated. Has characteristics.

To this end, the sole 10 made of urethane material or the like has an arch region 11 to which the arch of the sole touches, and an anterior region 12 to which the toe and heel touch, and a rear region to which the heel touches, based on the arch region 11. (13) is provided.

In particular, the front region 12 and the rear region 13 are integrally formed in the sole with a plurality of protrusions 14 having a predetermined height that can mitigate the impact when walking.

For example, the plurality of protrusions 14 may be integrally molded together at the sole injection molding.

Here, the protrusions 14 may be formed in a cylindrical shape, the shape of the protrusions 14 at this time is not limited to the cylindrical shape if it is a shape that can buffer the impact while stimulating the sole, or give acupressure effect Various shapes can be applied regardless of the shape.

In addition, the plurality of protrusions 14 formed in each region may be formed in an irregular arrangement form or a regular arrangement form in which a row and a row are aligned over the entire area of the front region 12 and the rear region 13. .

Preferably, based on adult shoes, approximately 20 projections 14 are formed in the front region 12 and 5-6 projections 14 are formed in the rear region 13, so that the front part of the sole of the foot is formed. It's a good idea to make sure you have a good balance between the back and the back.

In particular, in the case of the protrusion 14 formed in the rear region 13, it is preferable to form a groove portion 15 having a predetermined depth in the rear region 13 and to protrude from the bottom in the groove portion 15 thus formed. Do.

At this time, the height of the upper end of the groove portion 15 protruding from the bottom of the groove portion 15 can be located higher than the upper surface of the shoe sole.

The protrusion 14 is formed in the groove 15 of the rear region 13 when the insole 16 is covered on the sole 10, that is, when the insole 16 is covered on the protrusions. The space 17 may be formed around the spaces, and when the protrusions 14 are pressed by the heel, the air in the space 17 may be compressed to obtain an air cushion function using compressed air at this time. do.

In addition, in the present invention as a means for maintaining the rigidity of the sole 10 "

Provide a waist 18 in the shape of ".

Normally, the waist straps provided in the shoe are installed in a structure attached to nails, etc., the waist strap 18 provided in the present invention has a feature of being integrally installed in the sole 10 by being inserted at the sole injection molding.

Accordingly, unlike the shackles that are applied to existing shoes, even if the shoes are worn for a long time, they are maintained in a position that is disposed over the portions of the arch area 11 and the rear area 13, which are weak parts of the sole 10, without leaving their position. Thus, it is possible to obtain the advantage of increasing the durability and life of the shoe, such as to maintain the stiffness of the shoe for a long time.

That is, the waistband 18 is installed in a structure that is arranged over the inside of the upper surface of the arch region 11 of the shoe sole 10 and the inside of the upper surface of the groove 15 of the rear region 13, without fear of detachment It is possible to exert structural rigidity in position.

In addition, the functional shoe of the present invention can be used as a shoe sole 10 having a heel 22 as it is, but the step portion 19 is formed in the front of the bottom of the sole 10, step step 19 formed in this way ) Can be used by attaching the sole 20 made of a material such as rubber.

Therefore, looking at the state of use for the functional shoes of the present invention configured as described above are as follows.

Figure 4 is an enlarged view showing the state of use of the functional shoes according to an embodiment of the present invention.

As shown in FIG. 4, the functional shoe has a plurality of protrusions 14 integrally formed at the front region 11 and the rear region 13 of the inner bottom, and at the same time, has a heel 22 at the rear and An upper 21 is attached to the sole 10 to which 18 is inserted, and an insole 16 is installed on the inner bottom of the sole 10 so that the protrusions 14 may be covered, and the sole is forward toward the outer bottom. 20) may be attached to the form.

In the case of such functional shoes, when the user stepped on the foot, a plurality of protrusions 14 integrally formed on the sole 10 are pressed to compress and absorb the shock, thereby effectively alleviating the impact when walking. do.

In particular, since the plurality of protrusions 14 share the impact and absorb the shock, it is possible to obtain a more efficient impact mitigation effect.

In addition, in the case of the heel, since the air in the space 17 around the protrusions 14 is compressed, the air cushion acts as an air cushion, and thus cushions the air cushion with the elastic deformation of the protrusions 14. As the buffering effect is added, the most optimal buffering effect can be obtained.

In addition, since the sole 10 itself itself in the form of a single product can perform the role of the shoe as it is, it can significantly reduce the thickness of the sole of the shoe, and eventually increase the degree of freedom of design, such as design freedom associated with the shoe design can be increased. There is an advantage to that.
