Sole with resilience and shock absorbing function {Footwear sole having shock absorbing and repurcusion}

The present invention relates to a shoe sole to be used in a shoe is not only excellent resilience but also a technology for a shoe sole excellent shock absorption function.

In general, the sole basically has a function to absorb the shock generated during walking so that excessive shock is not transmitted to the body.

Of course, depending on the type of shoes, this function may be weakened.

Soles consist of outsoles, midsoles, and insoles, and most of the shock absorption is usually done in the midsole. The midsole is manufactured by foaming and has a shock absorbing function.

In general, rebound elasticity and shock absorption are considered to be opposite to each other, and high elasticity materials having excellent rebound elasticity are somewhat hard, and the shock absorption material has relatively soft characteristics.

Satisfying either repulsive elasticity or shock absorption is not difficult, but because only one of the functions is emphasized, the comfortable fit during walking was high, but there was a lack in reducing fatigue.

Accordingly, the present invention is to provide a shoe sole having a repulsion characteristic and a shock absorbing function that can provide a more improved walking characteristics by combining the two characteristics are excellent in the resilience characteristics and excellent shock absorption function in one sole.

The present invention for solving the above problems, in the sole, a midsole is formed in the depression recessed on the upper surface; A resilient elastic pad inserted into the recess and having a plurality of protruding support pillars contacting the bottom surface of the recess; Wrapping the support pillar is a shoe sole having a resilience and impact absorption function comprising a; shock absorbing pad embedded in the depression.

In addition, the resilient elastic pad is for a shoe sole having a resilience and impact absorption function, characterized in that the air pillar groove is opened to any one side in the center of the support pillar is formed.

In addition, the shock absorbing pad, a plurality of unit pads of different hardness is laminated and coupled, the sole layer having a resilience and impact absorption function, characterized in that an empty air layer is formed between the bottom of the unit pad and the bottom surface of the depression. It is about.

A shoe sole having resilience and shock absorbing function according to the present invention has an effect of providing a shoe that can reduce comfort and fatigue while having excellent resilience and shock absorbing function.

3 is a cross-sectional view of another embodiment of the present invention.

A shoe sole having a resilience and shock absorbing function according to the present invention will be described below in more detail with reference to the drawings.

The accompanying drawings show only one embodiment of the present invention and may be modified in various forms within the same technical category as the present invention.

1 is a plan view of an embodiment of the present invention, Figure 2 shows a cross-sectional view in FIG.

A shoe sole having a resilience and shock absorption function according to the present invention is the outsole 10 is located at the bottom of the sole like a conventional shoe sole and the midsole 20 is coupled to the outsole 10.

A concave depression 21 is formed on the upper surface of the midsole 20, and the depression 21 may be formed over the entire midsole 20 or may be partially formed as in the present embodiment.

In the present embodiment as shown in the figure it is to be formed in the recess 21 and the forefoot portion and forefoot portion is mainly a lot of load acting during walking.

The resilient elastic pad 30 and the shock absorbing pad 40 are installed in the recess 21 formed in the midsole 20, and the resilient elastic pad 30 and the shock absorbing pad 40 are alternately formed adjacent to each other. It shall be.

The resilient elastic pad 30 has a high elasticity, and a material such as urethane is suitable, and a plurality of support pillars 31 protruding to contact the bottom surface of the recess 21 are formed at the bottom of the resilient elastic pad 30. Only the support pillars 31 protruding from the entire area of the resilient elastic pad 30 come into contact with the bottom surface of the recessed portion of the midsole 20.

In addition, an open air pillar groove 32 may be formed at the center of each support pillar 31 of the resilient elastic pad 30. In the present embodiment, the air pillar groove 32 opening toward the upper surface of the resilient elastic pad 30 is formed for each support pillar 31.

The air column groove 32 formed for each support pillar 31 may be formed to be recessed from the bottom surface of the support pillar 31.

The resilient elastic pad 30 covers the recess 21 of the midsole 20, and the shock absorbing pad 40 is embedded in an empty space formed between the bottom surface of the resilient elastic pad 30 and the recess 21. . That is, the shock absorbing pad 40 is inserted into the recessed portion 21 and is coupled in a form to surround the support pillars 31.

The shock absorbing pad 40 has a soft characteristic unlike the resilient elastic pad 30. For example, when the hardness of the resilient elastic pad 30 is about 70 degrees, the hardness of the shock absorbing pad 40 is about 35 degrees. It should be about degree.

The shoe sole of the present invention in which the resilient elastic pad 30 and the shock absorbing pad 40 having the opposite characteristics are installed at the same time in one shoe sole harmonizes the advantages of the resilient elastic pad 30 and the impact absorbing pad 40. To improve the walking characteristics.

On the contrary, the disadvantages of the resilient elastic pad 30 are complemented by the shock absorbing pad 40, and the disadvantages of the shock absorbing pad 40 are complemented by the resilient elastic pad 30, thereby providing excellent characteristics through complementary actions. Will be exercised.

The shock absorbing pad 40 smoothly absorbs the shock during walking to reduce the shock transmitted to the body, and the resilient elastic pad 30 supports the sole of the user with high elasticity to give a light feeling when walking. It provides a feeling of wearing like walking in a state of zero gravity.

In addition, an acupressure protrusion 33 protruding upward may further be provided around the air pillar groove 32 formed along the center of the support pillar 31. The acupressure protrusion 33 is intended to protrude while forming a substantially circular circumference of the support pillar 31 and to cause a stimulus to the sole.

3 is a cross-sectional view of yet another embodiment of the present invention, showing a cross-sectional view of a portion corresponding to the line A-A and B-B in FIG.

The same structure as in the embodiment described above, but the shock absorbing pad 40 is made of a stack combination of a plurality of unit pads (40-1, 40-2, 40-3), the lower unit pad 40 of the lowest layer There is a difference in that an air space 50 is formed between the bottom surface of the recess 3 and the bottom of the recess 21.

The resilient elastic pad 30 having the support pillar 31 is coupled to the depression 21 of the midsole 20, and the shock absorbing pad 40 has a resilient elastic pad 30 to surround the support pillar 31. It is installed between the air layer (50).

In particular, the shock absorbing pad 40 is made of a laminated coupling form of a plurality of unit pads of different hardness, in the present embodiment it is assumed that the three unit pads are combined.

The upper upper pad 40-1 has a hardness of approximately 70 degrees, the middle upper pad 40-2 has a hardness of approximately 50 degrees, and the lower unit pad 40-3 has a hardness of approximately 30 degrees. It can be configured as

In addition, the lower unit pad 40-3 maintains the separation distance from the bottom surface of the recess so that the air layer 50 is formed between the shock absorbing pad 40 and the bottom surface of the recess.

The shock absorbing pad 40 including the plurality of unit pads 40-1, 40-2, and 40-3 may be absorbed in steps and air is formed on the bottom surface of the recess to form an air layer 50. There is also an advantage that can be expected by the buffer effect.

A shoe sole having a resilience and shock absorption function according to the present invention is absorbed most of the shock by the shock absorbing pad 40 when walking, and also the shoe sole that was compressed by the excellent elastic restoring force of the resilient elastic pad 30 is quickly restored. When walking, the user can feel walking very lightly.
