Description

Sole with shock absorption, dispersion and flexibility

The present invention relates to a shoe sole with enhanced impact absorption, dispersibility and flexibility.

In general, shoes are worn to protect the human foot, and are manufactured and marketed in a wide variety of forms 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 made up of a shoe sole to increase the frictional force of the to improve the walking, and to mitigate the impact on the soles of the foot when walking.

In the case of the conventional shoes as described above, insoles are placed on the inner bottom surface of the shoes to absorb shocks transmitted from the ground to the soles when walking, or the soles and heel portions are made of rubber and foam sponge material having excellent buffering capacity, Or it is known to incorporate elastic restorations, such as an air bag and a spring, in a shoe sole.

As described above, when manufacturing a shoe sole made of rubber or foam sponge, or when an elastic restoring body 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 is in contact with the ground while having a circular arc shape, there is a problem that the conventional general shoe can hardly contribute to the side to perform a 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 actively applied, and the ball with the shock absorption during walking Functional shoes are also provided that allow for natural and efficient propelled walking as if rolling on a flat surface.

Conventionally known conventional walking propulsion members are applied only to the heel portion of the sole, so that the short-term cloud walking can be achieved at the initial point of walking when the heel is in contact with 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 rolling cannot be performed over the entire length of the foot when the wearer walks, so that the joint protection of the pedestrian's knee and foot and the fatigue reduction effect of the foot are somewhat reduced. In the case of the conventional walking propulsion member, as in the case of an airbag or a spring, it is manufactured as a separate part from the sole and embedded in the sole, thereby increasing the manufacturing cost of the shoe due to the cumbersome process according to the manufacture of the sole. It also became.

The present invention is to provide a shoe sole that is enhanced in shock absorption, dispersibility and flexibility.

An embodiment of the present invention is formed in a region corresponding to the foot of the foot, the first region having an upper surface and a lower surface; A second region formed in an area corresponding to the forefoot of the foot and having an upper surface and a lower surface; And a third region formed in an area corresponding to the midfoot portion of the foot, wherein the third region connects the first and second regions to each other, wherein at least one of the first region to the third region has a plurality of recesses on the upper surface and the lower surface. A portion is arranged, and each of the concave portions discloses an impact absorbent, dispersibility and flexibility enhanced sole formed in the form of gradually decreasing width as the depth deepens.

The recess may include a plurality of stepped surfaces.

The concave portion formed on the upper surface and the concave portion formed on the lower surface may be formed so that their centers do not overlap each other.

The concave portion formed on the upper surface and the concave portion formed on the lower surface may be formed such that their centers overlap each other.

The recess formed in the upper surface and the recess formed in the lower surface may be connected to each other by a through hole.

The recesses may be arranged in a plurality of rows along the longitudinal direction of the shoe sole, and in a plurality of rows along a direction perpendicular to the length direction.

Convex portions may be formed on outer sides of the concave portions formed on the upper and lower surfaces, and a friction pad may be attached to the convex portions of the lower surface.

The concave portion may be any one selected from a circle, an ellipse, a triangle, a rectangle, a pentagon, a hexagon, a cross, a star, or a heart.

In the sole according to the present invention, a plurality of recesses and convex portions are formed on each of the upper and lower surfaces of at least one of the first region corresponding to the rear portion and the second region corresponding to the forefoot portion, thereby providing a shock absorbing space as compared with a general shoe sole. Increases. Therefore, not only the shock absorption from the outside is improved, but also the dispersibility of the impact is improved. In addition, the sole according to an embodiment of the present invention is arranged with a plurality of recesses at a predetermined interval in the form of a checkerboard or matrix, in particular a plurality of recesses arranged in a direction substantially perpendicular to the longitudinal direction of the foot as well as the approximately longitudinal direction of the foot. As a result, the degree of freedom in the deformation direction of the sole is increased, and thus the flexibility of the sole is also improved.
