Description

Cushion shoes & cushion insole {CUSHIONING SHOES AND CUSHIONING SHOE INSOLE}

The present invention relates to a cushioning shoe and a cushioning insole mounted to the shoe.

In general, shoes have been used in various forms and types to protect the foot 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.

Insoles can be divided into insoles (midsoles), midsoles (midsoles), and outsoles (soles), and insoles are often used on top of the soles, that is, on the tops of insoles.

The present inventors have invented the Republic of Korea Patent No. 10-0552090 "Shoes", the prior art is to mount a cushion member protruding downward from the bottom of the sole, to allow the air flow passage to communicate with the cushion member, You can see great exercise effect in your daily life without any space restrictions, and protect your knees and ankle joints with cushioning force of cushion member, and discharge harmful substances such as foot smell and sweat through the air flow to the wearer's foot Proposed shoes that can keep you healthy at all times.

The present invention is proposed to improve the prior art as described above.

The following points have been derived as improvements of the prior art as described above.

In the prior art, since the cushion member protrudes downward from the bottom of the midsole, its unusual shoe structure is likely to attract other people's eyes, so those who are distracted by those around them are reluctant to wear it.

In the prior art, the cushion member protrudes downward from the bottom of the midsole, and the bottom surface of the downwardly protruding cushion member comes into contact with the ground, whereby the landing area is narrowed.

In the prior art, the cushion member protrudes downward from the bottom of the midsole, and thus, the latest active walking type shoes (also known as masai walking shoes) are formed in an arc shape in which the sole of the sole protrudes downward to protrude downward. It was difficult to apply.

In order to solve the above problems, the cushion member is inserted into the midsole, but the cushion member does not protrude from the midsole so that the cushion member does not protrude from the lower surface of the midsole, that is, the overall shape of the shoe can be variously designed. However, there are the following problems when attempting such a design.

The height of the cushion member must be very small in order for the cushion member to be inserted inside the midsole so that the bottom of the cushion member does not protrude from the lower surface of the midsole. That is, it is possible if the height of the cushion member is much smaller than the height of the midsole. The smaller height of the cushion member also means that the amount of air that can be filled inside the cushion member is small, which means that the amount of air that can be flowed is reduced.

-In order for the cushion member to be inserted into the midsole so that the bottom of the cushion member does not protrude from the lower surface of the midsole, the portion of the midsole into which the cushion member is inserted must have a certain thickness. The part having a thickness enough to be inserted into the heel is mainly a heel part, and since such a part is a part that is subjected to a considerable impact in landing, etc., it can absorb the shock at the landing and lose weight while standing still. It should be designed to be strong enough to support it. However, when the cushion member is inserted into the midsole, the portion occupied by the midsole decreases as much as the cushion member is inserted. Therefore, most of the shock and load must be absorbed by the cushion member, but the amount of flowing air of the cushion member is reduced, so that the landing shock is properly absorbed. It's difficult and hard to have enough strength to support your weight.

In order to solve this problem, in order to increase the support strength of the cushion member, the cushion member made of synthetic resin should be able to increase the amount of air flowing (ie, the amount of air that can be filled) while becoming harder. However, when the cushioning member becomes harder, this means that the cushion becomes smaller, which results in a decrease in the amount of air that can be flowed, which conflicts with the problem of increasing the flow amount of air.

Therefore, the cushion member is inserted into the midsole, but the cushion member does not protrude from the lower surface of the midsole, but the rigidity of the cushion member while trying to propose a new structure of the cushion shoes that can increase the amount of air flow.

In addition, the present invention, as well as applying the cushion member to the midsole, can also be applied to the shoe insole.

In order to solve the above problems, the present invention, in the cushion shoes, the cushion member insertion portion is formed to be concave upwards on the lower heel portion, in communication with the cushion member insertion portion in order to discharge air to the upper front heel portion A midsole in which a flow path is formed; A semicircular cross-section is formed extending from the edge of the bottom and the bottom and the outer convex semicircular cross-section is formed of a cushion forming a closed curve structure and extending from the upper edge of the upper portion of the cushion portion to the inner side, the center of the auxiliary cushion portion is opened, The air filled therein is inserted into the cushion member insertion part so as to flow along the air access passage by vertical contraction and restoration of the cushion part and the auxiliary cushion part. A cushion member provided to be positioned high; An outsole fixed to the bottom surface of the midsole and the bottom surface of the cushion member at the same time to fix the cushion member; It comprises a, it is preferable that a plurality of incision grooves are formed radially outward from the center open to the auxiliary cushion portion.

According to the present invention as described above, while the cushion member is not protruded from the midsole or insole body, it is possible to increase the air flow while the cushion member is hardened, thereby applying elasticity and air cushioning action of the cushion member itself to shoes of various designs. New types of cushioning shoes and shoe insoles.

Hereinafter will be described in detail the configuration and operation according to the first embodiment of the present invention.

Figure 1 is a perspective view of the sole of the first embodiment according to the present invention, Figure 2 is a plan view of Figure 1, Figure 3 is a cross-sectional view AA of Figure 2, Figure 4 is a BB section of Figure 2, Figure 5 3 is an exploded cross-sectional view, FIGS. 6 and 7 are a perspective view and a plan view of the cushion member inserted into FIG. 1, and FIG. 8 is a cross-sectional view taken along CC of FIG. 7.

The shoe of this embodiment has a sole of the same type as in FIG. 1.

1 is a state in which the midsole 100 and the sole 200 of the sole is bonded, an insole (insole, not shown) may be provided on the upper portion of the midsole 100.

In addition, in Figure 1, between the midsole 100 and the sole 200, a cushion member 300 is built in the heel portion.

First, the midsole 100 will be described.

On the upper surface 110 of the midsole 100, an air access passage 111 is formed in a groove shape.

In addition, the lower surface 120 of the midsole 100, the heel portion is formed with a cushion member insertion portion 121 to concave upward.

In addition, a connection passage 122 is formed between the cushion member inserting portion 121 and the air access passage 111 so that the cushion member inserting portion 121 and the air access passage 111 communicate with each other.

The cushion member 300 is mounted to the cushion member insertion portion 121 of the midsole 100.

The cushion member 300 is made of a single resin material (eg, P.U., etc.) by injection molding, and its structure includes a bottom part 310, a cushion part 320, and an auxiliary cushion part 330.

The bottom 310 seals the lower portion. The bottom 310 is in the form of a flat plate, the shape may be a horseshoe shape as shown in Figs. 6 and 7 or a circular shape as shown in Figs. 9 and 10, in addition to the various forms can be applied Can be.

Cushion 320 is formed extending from the edge of the bottom 310 to the top and as shown in Figs. 8 and 11, the semicircular cross-section is convex outward to form a closed curve structure can be contracted and restored up and down.

The auxiliary cushion portion 330 extends upward from the upper edge of the cushion portion 320. In addition, the center of the auxiliary cushion portion 330 is open.

In addition, the auxiliary cushion portion 330 is formed with four incision grooves 331 radially from the open center toward the outside.

As such, the auxiliary cushion portion 330 is formed in the upper portion of the cushion portion 320 so that the amount of air that can be filled in the cushion member 300 increases, and the cushion member 300 moves downward from the upper portion thereof. When receiving a force (that is, when receiving a shock when landing), the auxiliary cushion unit 330 is first subjected to the force, and then has a structure such that the cushion unit 320 is compressed.

Therefore, when a large force is applied, the cushion portion 320 is compressed very little compared to the large movement of the auxiliary cushion portion 330 downward. This structure considers that the cushion member 300 is harder than the conventional one. If the cushion member 300 is made of a relatively soft product instead of hardening, the cushion part 320 itself may be greatly compressed and increase the amount of air flow under a large force, but the cushion part 320 itself may be increased. Due to their low stiffness, they will not absorb landing shocks properly or will not support their weight.

In addition, the cutting grooves 331 formed in the auxiliary cushion part 330 are formed so that the auxiliary cushion part 330 can be moved better downward even with a small force. This is because the cushion member 300 uses a harder material, and thus, if there are no cutout grooves 331, the downward movement of the auxiliary cushion part 330 is prevented due to the rigidity of the cushion member 300.

In addition, the auxiliary cushion portion 330 is formed with a tube groove 332, the air flow pipe 112 is provided along the tube groove 332, the connecting passage 122, the air access passage 111.

Therefore, the air filled in the cushion member 300 may move to the upper front portion (anterior heel portion) of the shoe through the air flow tube 112 according to the up and down contraction and restoration of the cushion unit 320 and the auxiliary cushion unit 330. have. Air moved from the cushion member 300 to the front of the shoe may be discharged to the front of the shoe inside through the air hole formed in the insole (not shown).

As such, the bottom portion 310 of the cushion member 300 inserted into the cushion member insertion portion 121 is positioned at the same level or higher than an extension line of the lower surface 120 of the surrounding midsole 100. That is, the cushion member 300 does not protrude downward from the lower surface of the midsole 100. By such a structure, the overall shoe design can be designed in various forms regardless of whether the cushion member 300 is inserted.

The sole 200 is provided below the midsole 100.

The sole 200 is fixed while contacting both the lower surface 120 of the midsole 100 and the bottom 310 of the cushion member 300. Therefore, the cushion member 300 may be seen to be fixed by the cushion member insertion portion 121 and the sole 200 of the midsole 100.

20 is a perspective view of the insole of the fourth embodiment according to the present invention, FIG. 21 is a plan view of FIG. 20, and FIG. 22 is a sectional view taken along line H-H of FIG. 20.

This embodiment applies the technical idea of the present invention to the insole.

In general, the general insole of the thin thickness is not applicable to the present invention, but in order to make the height of the insole is very thick insole (so-called "height height insole"), the technical idea of the present invention can be applied.

In general, the height of the insole is composed of a very thick and highly cushioned insole body 400 and a cushioning window (not shown) bonded to the upper surface of the insole body 400.

20 illustrates only the insole body 400 and the cushion member 300 provided therein.

First, the insole body 400 will be described.

The air inflow passage 411 formed in the insole body 400 is formed with a hole in the lower right side of the upper 410 and then extends to the rear portion in the form of a groove along the lower surface 420 and then opens the inside of the insole body 400. Gina is connected to the cushion member insertion portion 421.

In addition, the lower surface 420 of the insole body 400, the heel portion is formed with a cushion member insertion portion 421 concave upward.

The cushion member 300 is mounted on the cushion member insertion portion 421 of the insole body 400.

The form and installation structure of the cushion member 300 are the same as in the first embodiment. However, the tube groove 332 is formed in the shape of a hole in the cushion portion 320 of the cushion member 300, the air flow pipe 412 is provided along the tube groove 332 and the air access passage 411.

Accordingly, the air of the cushion member 300 may move to the front of the shoe along the air flow pipe 412. The air moved from the cushion member 300 to the front of the shoe may be discharged to the inside of the shoe through an air hole formed in a protective window (not shown) provided on the upper surface of the insole body 400.

As such, the bottom portion 310 of the cushion member 300 inserted into the cushion member inserting portion 421 is positioned the same as or higher than an extension line of the lower surface 420 of the surrounding insole body 400. That is, the cushion member 300 does not protrude downward from the bottom surface of the insole body 400.

In some cases, in order to firmly couple the insole body 400 and the cushion member 300, a separate outsole (not shown) may be provided at the lower portion of the insole body 400, but a sole is provided (not shown). Even if you don't, the insole is installed inside the shoe so it doesn't matter.

Meanwhile, in the above embodiments, one air access passage communicating with the inside of the shoe is communicated with the cushion member, but as mentioned in the prior art, the other air access passage allows the interior of the cushion member of the present embodiment to communicate with the outside of the shoe. By forming a separate and providing a check valve to block the air flow to the outside of the shoe in the air flow passage, the air flows into the cushion member from the outside of the shoe and may form an air flow to the air from the cushion member to the inside of the shoe have.

Embodiments of the present invention as described above are only 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. Such modifications and adjustments fall within the scope of the present invention if they use the technical idea of the present invention.
