Description

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

The present invention relates to a shoe midsole having a shock dispersing function and a cloud walking function, and more particularly, by forming a cushioning space formed in the shoe sole narrowly only on the heel portion and the sole of the foot along a walking load path. While maintaining the function, the midsole and the upper can be formed as wide as possible to increase the adhesion between the midsole and the upper to produce high-quality shoes, while the midsole and the sole, except the buffer space narrowly formed on the heel and the sole It relates to a shoe midsole having an impact dispersion function and a cloud walking function to simplify the structure of the midsole so that the adhesive area with the upper replaces the function of the rib.

In general, shoes are worn in order to protect the human foot, and are manufactured and marketed in a wide variety of shapes and types. However, shoes are usually covered by covering the instep of the foot and the ankle, and the sole is protected from the ground while protecting the sole. It is composed of a shoe sole to increase the frictional force 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, in recent years, a great deal of time and effort has been put into the development of functional footwear that prevents excessive stress on the joints and soles of the knees and feet of the wearer and contributes to health promotion by simply walking and wearing shoes. Investing.

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 described above, the functional footwear that enables the cloud walking is known as a shoe midsole having a shock dispersion function and a cloud walking function of Korean Patent No. 0884659 (Registration Date: February 12, 2009) registered by the applicant.

1A is a perspective view of a shoe midsole having an impact dispersion function and a cloud walking function pre-registered by the applicant, and FIG. 1B is a cross-sectional view of FIG. 1A applied to a shoe sole 10 to serve as a cushioning material for supporting a walking load. In the shoe midsole 11, the upper surface of the midsole 11 is formed with a buffer space 12 as an empty space from the heel portion to the toe portion along the outer portion of the sole, the buffer space 12 ) Is formed so that the flat cross-sectional area is increased toward the heel and toe part of the sole of the midfoot arch of the sole, and at the bottom of the midsole 11 at regular intervals along the longitudinal direction of the midsole 11 18 is formed, and the buffer space 12 has a configuration in which the rib 17 protrudes along a portion corresponding to the incision groove 18.

The buffer space 12 reduces the substantial volume of the midsole 11 that elastically supports the load of the human body along the walking load path, so as to reduce the support force of the midsole 11 with respect to the load of the human body in that portion. Accordingly, the compression deformation of the midsole 11 due to the load of the human body is to be expressed differently for each sole area by the buffer space 12, and the compression-deformed midsole 11 portion is restored to its original state when the load is removed. will be.

That is, when the load of the human body acts along the walking load path, the compressive strain of the midsole 11 increases at the heel portion and the toe portion, and the compressive deformation amount increases from the heel and the toe to the center portion of the sole corresponding to the midfoot arch. By reducing, the deformation line of the midsole 11 due to the load of the human body is formed in an arc shape suitable for the propelled rolling walk along the walking load path.

The incision groove 18 is easily bent along the walking path to the shoe sole 10 during walking to make the cloud walking more smoothly, while each incision groove 18 is the side and bottom of the shoe sole 10 By exposing through the part to the structure of the midsole 11 is to be expressed through the shoe sole 10 and to contribute to the improvement of appearance.

The rib 18 wears shoes such that a non-illustrated shoe insole (insole), which is typically covered at the top of the midsole 11 in the sole 10, is more firmly supported by the rib 17. The load distribution function and the propulsion rolling function are achieved without disturbing one's walking.

As described above, the applicant's shoe midsole of the pre-registered Patent No. 884659 can efficiently perform the impact dispersion function and the cloud walking function, but the toe portion along the outer portion of the sole from the heel portion to the upper surface of the midsole 11 The adhesion area between the midsole 11 and the upper coupled to the midsole 11 is markedly reduced by the buffer space 12 formed as an empty space, which decreases the adhesion between the upper and the midsole 11. In addition to the problem of causing mass production of defective products, the ribs 17 are formed in the buffer space 12, which makes the structure of the midsole 11 complicated, thereby increasing the cost of shoes. Will be.

The present invention by narrowly forming the buffer space formed in the shoe sole solely to the heel portion and the sole portion along the walking load path in order to improve the problems of the prior art registered by the applicant as described above, the impact dispersion function and the cloud walking function as it is While maintaining the adhesive area between the midsole and the upper as wide as possible to increase the adhesive strength of the midsole and the upper to manufacture high-quality shoes, while the midsole and the upper with the exception of the buffer space narrowly formed on the heel and the sole The technical problem is that the adhesive area replaces the function of the rib so that the structure of the midsole can be simplified to contribute to manufacturing cost reduction.

The present invention is a buffer space as an empty space is formed on the upper surface of the shoe midsole that serves as a cushioning material to support the walking load, the bottom portion of the midsole is formed at regular intervals along the longitudinal direction of the midsole is formed In the cushioning space, the shoe sole is formed with a rib, the buffer space is characterized in that formed in a width of 1 ~ 10mm with a predetermined interval on the heel portion and the sole of the midsole.

As another embodiment of the present invention, the buffer space and the rib formed in the midsole are removed.

According to the present invention as described above, in the shoe midsole formed with a buffer space along the walking load path, by forming the buffer space narrowly on the heel portion and the sole portion while maintaining the impact dispersion function and cloud walking function in the midsole and upper The adhesion area between the midsole and the upper is ribbed, except that the cushioning area formed on the heel and the sole is narrow, so that the shoes can be manufactured with high quality. By simplifying the structure of the midsole to replace the function of will have the effect of contributing to the reduction of manufacturing cost.

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

Figure 2a is a perspective view of a shoe midsole having an impact dispersion function and a cloud walking function according to the present invention, Figure 2b is a cross-sectional view of Figure 2a, a shoe midsole applied to a shoe sole to serve as a cushioning material to support the walking load (11) is provided, the heel portion and the sole portion of the upper surface of the midsole 11 is formed with a width of 1 ~ 10mm, a buffer space 12 as an empty space is formed, the bottom portion of the midsole 11 The cutting grooves 18 are formed at regular intervals along the longitudinal direction of the midsole 11, and ribs 17 are formed between the buffer spaces 12.

Wherein the buffer space 12 is not less than 1mm in width can not be smoothly performed impact dispersion function and cloud walking function, when formed in the width of 11mm or more, the adhesion area with the upper becomes less production of defective products It becomes preferable to form in 1-10 mm width by becoming a factor.

The midsole for shoes 11 to be applied to the present invention is a cushioning material for absorbing the impact applied to the sole when walking using synthetic rubber such as natural rubber or synthetic rubber or polyurethane foam or polypropylene.

When the midsole 11 for shoes according to the present invention is based on the sole of the human body, the buffer space 12 as an empty space of 1 to 10mm wide in the portion corresponding to the heel and the sole, the midsole 11 Is formed at a predetermined depth at the bottom of the), the buffer space 12 is preferably such that the depth of the buffer space 12 is in the range of 1/2 ~ 2/3 of the entire thickness of the midsole (11).

The buffer space 12 reduces the substantial volume of the midsole 11 that elastically supports the load of the human body along the walking load path, so as to reduce the support force of the midsole 11 with respect to the load of the human body in that portion. Accordingly, the compression deformation of the midsole 11 due to the load of the human body is to be expressed differently for each sole area by the buffer space 12, and when the load is removed, the compression-deformed midsole 11 portion is restored to its original state. .

In other words, when the load of the human body acts along the walking load path, the compressive strain of the midsole 11 increases at the heel portion and the sole of the foot, and the compressive strain decreases toward the central portion of the sole corresponding to the midfoot arch. Deformation diagram of the midsole 11 by the load of is to form an arc shape suitable for the propelled rolling walk along the walking load path.

In addition, when the buffer groove 16 is formed to be inclined with respect to the midsole 11, there is an advantage that the compression strain of the midsole 11 sufficient for rolling gait at the corresponding portion can be obtained, the buffer groove 16 It is most preferable in terms of cloud walking that the angle of inclination of the wearer is within the range of 16 to 20 degrees formed by the foot and the ground when the wearer walks.

The bottom portion of the shoe midsole 11 according to the present invention is formed with a cutting groove 18 at regular intervals along the longitudinal direction of the midsole 11, the cutting groove 18 is a shoe sole during walking (10) C) is easily bent along the walking path to make the cloud walking more smoothly, while each incision groove 18 is exposed through the side and bottom of the shoe sole 10 so that the structure of the midsole 11 It is to be expressed through the sole 10 and to contribute to the improvement of appearance.

In addition, the incision groove 18 is also formed in the vertical direction with respect to the midsole 11 similarly to the buffer groove 16 described above, and in the portion corresponding to the heel and the toe, the incision groove 18 is outer side. It is preferable to be inclined with the midsole 11 toward the direction.

In addition, the shoe midsole 11 of the present invention automatically ribs 17 between the buffer space 12 when the buffer space 12 described above is formed in the heel portion and the sole portion in a width of 1 to 10 mm. As illustrated, a shoe insole (insole), which is not covered at the top while simplifying the structure of the midsole 11, is more firmly supported by the rib 17 having a large area, so that it is possible to walk the person wearing the shoe. It is intended to achieve the load distribution function and the propulsion rolling function by the buffer space 12 described above without causing any trouble.

In particular, since the buffer space 12 is formed in the heel portion and the sole portion having a width of 1 ~ 10mm, the rib 17 has a large area, which is soon included in the adhesion area with the upper midsole 11 and The adhesive area with the upper is formed as wide as possible to be firmly combined to produce high quality shoes.

When the shoe midsole 11 of the present invention is applied to a shoe sole as described above, a part of the sole from which the walking load is substantially applied when the wearer walks, that is, the part from the heel to the toe through the lateral surface of the sole of the foot The buffer space 12 or the buffer groove 16 can be supported more comfortably, thereby reducing the fatigue applied to the soles of the wearer during the walking process.

In particular, as the buffer space 12 or the buffer groove 16 can perform a more natural and efficient propulsion rolling gait over the entire surface of the sole from the heel of the wearer to the forefoot and the toe, The joints of the knees and ankles of the field can be more securely protected, thereby further contributing to the health promotion aspect of the wearer.

3 is a perspective view of a shoe midsole having an impact dispersion function and a rolling walking function according to another embodiment of the present invention, and removes the buffer space 12 and the rib 17 formed on the upper surface of the shoe midsole 11.

In other words, by removing the buffer space 12 and the rib 17, the entire upper surface of the midsole 11 as an adhesive surface with the upper to further increase the adhesive force, the impact dispersion function and rolling gait due to the reduction of stability and resilience elasticity The function may be somewhat deteriorated, but it can be applied differentially according to consumers' preferences and product grades.
