BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to shoe midsoles and thrusts, and more particularly, to shoe soles and shanks used for midsoles that can comfortably and effectively support a foot.

In recent years, due to the increase in artificial structures, many people are moving on hard concrete and asphalt, and the shock applied to the body through the sole of the foot when walking is causing pain in various joints connected to the feet, knees and parts of the body. Can be induced. Thus, the importance of shoe midsoles directly touching the feet to protect the feet and joints from these shocks is increasing day by day. Indeed, there are already insoles that can use foam to provide cushioning and shock absorption to the shoe, but in practice they are almost exclusively used in sneakers, and these foam insoles can simply provide a soft fit, thus making it easier to shape the foot. It cannot be said that it responds directly.

These insoles are not suitable for shoes other than sports, such as shoes, and furthermore cannot be used for straightening feet or for other therapeutic purposes. For example, when the insole composed of the conventional foam described above is used for the shoe, the height of the shoe is increased by the insole using the foam as a whole, thereby impairing the overall appearance of the shoe. This can come off well.

In particular, in the case of shoes, a midsole using a thrust is used. Shank is to enter the portion corresponding to the center of the sole of the sole of the midsole, it can function to maintain the shape of the shoe with an iron core or iron piece as the spine of the shoe and prevent it from peeling off. Therefore, lumbar braces are generally used to support recesses in the soles of the feet, usually extending from the heel to the location of the spring.

Lumbar braces play an important role in maintaining the shape of the shoe as an element for supporting the shoe midsole. However, since the waistband is generally formed of a metal such as iron, it is difficult to further form another structure in the region where the waistband is located in the midsole.

One aspect of the present invention provides a waist strap that can provide a variety of structures to the shoe midsole and a shoe sole employing the same.

One aspect of the present invention provides a shoe midsole that allows the user to comfortably walk.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the shoe midsole partially wraps the cushion portion and the cushion portion formed in the midsole base to correspond to the sole portion, the midsole base formed to correspond to the sole of the shoe And a waistband secured to the midsole base. The waistband is generally formed from the heel region of the midsole to the yongcheon region, and the cushion portion is formed to correspond to the yongcheon region so that the user can feel comfortable.

In particular, the waist strap may be formed to surround the cushion portion so as not to interfere with each other in the spring area. For example, the waistband may be made into a U-shaped shape and the cracked portion of the waistband may be positioned around the cushion portion. It is also possible to make the waist shaping in a U-shape or U-shape and to have the cracked portion of the shackle positioned around the cushion portion. In some cases, two separately manufactured waistbands may be attached to the midsole base so that the two waistband combinations are around the cushion portion.

Since the conventional straight waistband extends to the spring area, it may prevent the cushion portion from being formed wide. On the contrary, if a straight waistband is made short to form a wide cushion, it is difficult for the waistband to perform a function of supporting the shoe. However, in the present invention, since the waist strap supports the periphery of the cushion portion, it is possible to secure a sufficient length for performing the function, and it is possible to form a wide cushion portion.

The cushion portion may be formed in the midsole base and may be attached separately. In some cases, a through hole may be formed at a position corresponding to the yongcheon couple in the midsole base, and a cushioning portion may be formed in the midsole base by filling the through hole with a foamable resin or other high elastic resin.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments. For reference, in the present description, the same numbers refer to substantially the same elements, and may be described by quoting the contents described in other drawings under the above rules, and the contents repeated or deemed apparent to those skilled in the art may be omitted.

1 and 2, the shoe midsole 100 includes a midsole base 110, a cushion unit 120, a waistband 130, and a midsole endothelium 140.

The midsole base 110 is formed in a shape corresponding to the sole of the shoe and may be formed of a general midsole material. A through hole 112 is formed in the midsole base 110 corresponding to a portion corresponding to the spring in the foot structure, and the through hole 112 is filled with a high elastic resin such as an expandable resin to form the cushion part 120. have. The cushion unit 120 may be manufactured separately and fitted into the through hole 112, and in some cases, the liquid resin or the resin in the fluid state is formed and integrally formed in the midsole base 110 having the through hole 112 formed therein. It may be provided by.

In the present exemplary embodiment, the cushion part 120 is formed to correspond to the through hole 112 of the midsole base 110, but according to another embodiment, the cushion part may be provided without forming a through hole in the midsole base. For example, a cushion portion may be formed by attaching a separate cushion member to the midsole base.

Referring back to FIGS. 1 and 2, the waistband 130 may be provided in an approximately U-shaped shape. The waistband 130 specifically includes a body portion 132 and a branch portion 134, the body portion 132 is formed and fixed in the longitudinal direction to the midsole base 110, the branch portion 134 is the body Split into two portions from the portion 132 extends around the cushion portion 120. Fixtures such as rivets 136 may be used to secure the brace 130, and other adhesives may be additionally used.

The midsole endothelium 140 is provided on the hem 130 and the midsole base 110, and the midsole endothelium 140 may be provided as a product by covering the hem 130 and the midsole base 110. For reference, in this embodiment, the waistband 130 is attached on the midsole base 110, but in some cases, the waistband may be provided on the bottom surface of the midsole base.

Referring to FIG. 2, the cushion unit 120 may be formed to correspond to the spring area of the sole, and may sufficiently support the portion Y corresponding to the spring in general. In addition, because the waistband is extended by bypassing the periphery of the cushion portion 120, it is possible to secure a sufficient length to support the sole of the shoe shape.

FIG. 3 is a plan view assuming a case in which a cushion part is formed in a conventional shoe midsole, and FIG. 4 is a plan view for explaining a case in which a cushion part is formed using a V-shape waist in the shoe midsole of FIG. 1.

Referring to Figure 3, the conventional waistband 30 is formed in a straight line as a whole, extending from the heel region to the yongcheon region. Therefore, the cushion portion 20 is formed to a size that does not interfere with the waistband 30. Referring to the drawings, when the length of the waist 30 is L, the length of the cushion portion 20 is formed may be formed of C1.

Referring to FIG. 4, the waist shackle 130 is formed in a U-shape, and is formed to surround the periphery of the cushion part 120 in the spring area. Comparing the dimensions, when the total length of the waist 130 is the same as L, the cushion portion 120 can be formed to a size larger than the cushion portion size of Figure 3 as C2.

That is, under the same conditions, the cushion unit 120 according to the present embodiment may be formed over a wider area, and may provide the user with a more comfortable feeling. The wide cushion portion allows the user to stay comfortable for long periods of time and can greatly assist in improving foot health.

5 to 7 is a plan view for explaining a waistband according to other embodiments of the present invention. For reference, the midsole base 110, the cushion unit 120, and the like other than the waistband may refer to the above-described contents.

Referring to FIG. 5, the waistband 230 is formed in a U-shaped shape, and the branch part 234 connected to the body part 232 is formed in a U-shaped or yoke shape. Branches are not formed in a straight line like a general V-shape, and may be formed in various shapes while maintaining a similar connection relationship in some cases.

Referring to FIG. 6, two waistbands 332 and 334 may be mounted to the midsole base 110. The waistbands 332 and 334 are fixed to be spaced apart from each other, and the portions adjacent to the cushion portion may be positioned at both sides of the cushion portion. Even if the shackle is not formed as one component, the shackles 332 and 334 can be formed long, and in some cases, there is an advantage that the shackles can be applied.

Referring to FIG. 7, the waist 430 may also be provided in a U-shape. The lumbar 430 may extend branching from the heel region and extend so that each end is located at the side of the cushion portion. The U-shape waistband may be provided by one integrally manufactured part, but in some cases, a separately manufactured waistband iron piece may be fixed by arranging the U-shaped or U-shaped letter.

Cushion portions in the midsole can be formed over a fairly large area by using a thrust that splits into a U-shaped or U-shaped shape. In other words, even when the waistband is formed sufficiently long with minimal interference between the cushion section and the waistband, the cushion section can sufficiently support the spring area.

Shoes using the midsole for shoes of the present invention can provide a long period of comfort even when standing because it provides a wide cushion.

In addition, the cushion part may form a through-hole and use a high elastic resin filled therein, so that the entire thickness of the midsole may serve as a cushion, and even if a structure using the entire thickness as a cushion is formed, the influence of the thrust may be minimized. There is a number.
