Description

Shoe sole for shock absorbing}

The present invention relates to a shoe sole that can effectively absorb the impact when the wearer lands.

In general, shoes have been used in various forms and types to protect the feet when a person walks. The conventional shoe structure consists of an upper that protects the instep and ankle, and a sole that protects the sole and increases the frictional force with the ground while improving walking ability and simultaneously cushioning the upper. It is taking structure.

In addition, the sole is generally composed of a midsole (midsole), outsole (outsole, outsole), and the sole of the shoe sole consisting of the midsole is also produced and spread.

On the other hand, recently active walking shoes have been widely spread.

Korean Patent No. 10-0377822 "Active rolling device" discloses an active walking shoe having no heel of the shoe and the sole bottom of the shoe forms an arc. Shoes of this type are generally referred to as "cloud shoes," "active walking shoes," and "Masai walking shoes."

Such a shoe is divided into the following steps: i) landing, ii) centering the heel to the heel, iii) pushing the ground away from the heel, i) impacting the landing, especially the heel It is very important to absorb shocks effectively.

The present invention is to provide a shoe sole having a shock absorbing structure by the U-shaped tube-shaped airbag, cushion plate, and coil spring in order to effectively absorb the impact applied to the heel portion.

In order to solve the above problems, the present invention, the midsole 110, the cushion body receiving portion 111 is formed in the groove shape on the rear surface; An air bag 130 having a U-shaped tube seated in the rear of the cushion member accommodating portion 111 and disposed toward the front; The first cushioning body 141 and the U-shaped airbag seated on the cushion body accommodating part 111 and inserted between the U-shaped airbag 130 and having a spring through-hole 141a formed in a vertical direction in the center thereof ( Cushion plate 140 made of a synthetic resin foam consisting of a second cushion body 142 disposed in front of 130; A coil spring 150 inserted and seated in the spring through-hole 141a in a vertical direction; Characterized in that comprises a.

In the above, an air flow passage 112 is formed on the upper surface of the midsole 110 to communicate the cushion body accommodating portion 111 and the upper heel portion of the midsole 110, and the second cushion body 142. It is preferable that a cutout 142a communicating with the air flow passage 112 is formed in front of the).

In the above, it is preferable that the cutout 142a has a wedge shape in which the area decreases toward the rear side.

In the above, the width of the second cushion body 142 is preferably the same as the width of the U-shaped airbag 130.

In the above, it is preferable that the traction 120 is coupled to the upper surface of the midsole 110, and a plurality of air flow holes 121 are formed in the front heel.

According to the present invention as described above, the shock applied to the heel portion is effectively absorbed by the airbag in the form of a U-shaped tube, a cushion plate, and a coil spring.

Hereinafter, the specific configuration and operation will be described based on an embodiment of the present invention.

1 is an exploded perspective view of a shoe sole according to the present invention, FIG. 2 is an exploded perspective view of a state in which the main part of FIG. 1 is coupled to a shoe midsole, and FIG. 3 is a conceptual cross-sectional view of the coupled state of FIG. 1.

The shoe sole of the present embodiment is composed of a midsole 110, a traction 120, an air bag 130, a cushion plate 140, and a coil spring 150.

The midsole 110 of the present embodiment applied an active walking shoe sole having a lower longitudinal central portion thereof.

The cushion body accommodating part 111 is formed in the groove shape in the upper surface rear part of the midsole 110. As shown in FIG.

As for the planar form of the cushion body accommodating part 111, the back part takes the form of a horseshoe.

In addition, the upper surface of the midsole 110 is formed with an air flow passage 112 for communicating the cushion body receiving portion 111 and the upper front heel portion of the midsole 110.

An air bag 130 having a U-shaped tube is mounted to the rear of the cushion body accommodating part 111 having a rear portion having a shape such as a horseshoe.

That is, the airbag 130 has a U-shape disposed toward the front of the shoe, and the airbag 130 is located at the heel portion of the shoe.

The cushion plate 140 is seated in the remaining space of the cushion body accommodating part 111.

The cushion plate 140 may be made of a synthetic resin foam, and may be divided into a first cushion body 141 and a second cushion body 142.

The first cushioning body 141 is a portion inserted between the U-shaped airbags 130, and a spring through hole 141a is formed in the center in the vertical direction.

The second cushion body 142 is a portion disposed in front of the U-shaped airbag 130.

The width of the second cushion body 142 substantially matches the width of the U-shaped airbag 130.

A metal coil spring 150 is inserted and seated in the vertical direction in the spring through hole 141a of the first cushioning body 141.

In addition, a cutout portion 142a communicating with the air flow passage 112 is formed in front of the second cushion body 142.

Therefore, the site | part in which the cutout part 142a was formed is a site | part which remains as an empty space substantially in the cushion body accommodating part 111. FIG.

The incision 142a is wedge shaped to decrease in area toward the rear of the shoe.

As such, in the state in which the airbag 130, the cushion plate 140, and the coil spring 150 are mounted on the midsole 110, the texture 120 to the insole are adhered to the upper surface of the midsole 110.

In this case, a plurality of air flow holes 121 are formed in the front heel portion of the texture 120, and the air flow holes 121 have a structure in communication with the air flow passage 112.

The operation of this embodiment as described above will be described.

The most impacted area when a shoe user lands is the heel of the shoe.

In the present embodiment, a coil spring 150 having a relatively large rigidity is provided at the center of the heel portion so as to absorb a relatively strong impact at the heel portion of the shoe, and a shape such as a horseshoe around the coil spring 150 is provided. The U-shaped airbag 130 is disposed to effectively absorb the impact applied to the edge of the heel.

In addition, the first cushion body 141 provided between the coil spring 150 and the U-shaped airbag 130 (in fact, the coil spring 150 is mounted on the first cushion body 141) is very strong. By having a restoring force to maintain the arrangement structure of the coil spring 150 and the U-shaped airbag 130, and serves to assist the shock absorption.

In addition, the second cushion body 141 is disposed in front of the heel portion to absorb a relatively weak impact.

In addition, when the cushion plate 140 including the first cushion body 141 and the second cushion body 142 is compressed, air of the cushion body accommodating part 111, in particular, air located in the cutout 142 a flows through the air. It can be discharged to the air flow hole 121 along the passage (112), thereby enabling the ventilation of the inside of the shoe or the flow of air.

The above embodiments are merely preferred embodiments of the present invention, and the technical idea of the present invention may be variously modified or adjusted by those skilled in the art. If such modifications or adjustments use the technical idea of the present invention, it is within the scope of the present invention.

The present invention can be used as a shoe sole that can effectively absorb the impact when the wearer lands.
