Description

Shoe midsole having impact absorption power and pushing function}

The present invention relates to a shoe midsole, and more particularly, to a midsole having a shock absorbing and acupressure function by forming a plurality of accommodation spaces inside the shoe midsole and mounting a rubber ball having a shock absorbing material inside the space. will be.

In general, many kinds of shoes have been produced in recent years. Shoes can be roughly divided into shoes that emphasize appearance and sports shoes that emphasize function. In addition, the shoe has an upper part covering a large instep part and a window part which forms a bottom and contacts the sole. In particular, the sole is in contact with the ground, which is required to be abrasion resistance and non-slip, such as the upper part of the sole, the midsole is important to the shock absorbing function, and the upper part of the midsole in contact with the human foot There is this.

Today, since the impact transmitted to the feet by the weight when walking is very large, a lot of efforts are being made to improve the shock absorption function of the shoes regardless of the type of shoes. This is in line with efforts to improve the shock absorbing function of the midsole and much research has been done on the midsole.

Hereinafter, with reference to the drawings showing a conventional intermediate window will be described in detail.

1 is a perspective view of a conventional general intermediate window. As shown, the polymer material is molded through a press or an injection molding machine so that the specific gravity is low and the elasticity is imparted to form the same curvature as the bottom of the human foot. Thus, the function of the shock absorbing of the midsole 1 depends on the elasticity exhibited by the material itself and the microscopic space present inside the material. In order to improve the shock absorbing function of the middle window (1), which depends on the elasticity of the material itself, of course, a lot of research and development has been made on the development of the material of the middle window (1), and various kinds of materials are developed or adopted today It is used as a material of the middle window 1.

However, the dependence of the shock absorbing function of the midsole 1 on the material itself has the following problems.

The material used for the midsole 1 is a single foamed body such as urethane or E.V.A., which has a problem that it is difficult to obtain many effects on shock absorption as a single body. The material used for the middle window 1 has a certain shape and the whole inside and the outside are filled with tangible materials. When the shoe is in contact with the ground while wearing shoes, the midsole 1 is loaded by the weight. In order for the intermediate window 1 to have a shock absorbing function against the load applied in this way, a predetermined volume of the intermediate window 1 that expands in the horizontal direction (horizontal portion) when the load is applied in the vertical direction, that is, vertically downward by the foot, is applied. Should have the property to move to and then return to another part within the midsole 1 while maintaining the shape of the midsole 1, ie elasticity.

By the way, since the material of the middle window 1 has a certain shape and the whole inside and the outside are filled with tangible materials, the predetermined volume of the middle window 1 with respect to the load within a certain shape of the middle window 1 is different from the other part of the middle window 1. There is a problem that moving to. That is, the middle window 1 should be smoothly contracted and restored as the load is added or decreased. The space in which the horizontal expansion of the middle window 1 can be absorbed in accordance with the contraction of the middle window 1 due to the vertical downward load. There is a problem in that there is a limit to the shock absorption function of the middle window (1) due to the material itself.

In general, the shock absorbency and resilience play a role opposite to each other, the ergonomically the rear portion of the midsole (1), that is, the portion corresponding to the back of the foot squeezes the shock absorbency, the front portion of the midsole (1), ie near the toes The part that demands repulsion elasticity. However, when manufacturing the middle window (1) as a single body has a problem that it is difficult to satisfy the above functions because it is manufactured to have a suitable shock absorbing and resilience at the same time. In order to improve this, the receiving space portion is formed in the rear part of the middle window 1 to improve shock absorbency by inserting a material such as an air pump, spring, or jelly, but these materials are not excellent in absorbing shock because they have a large empty space.

Accordingly, the present invention is to solve the above problems, the individual shock absorbing members inserted by inserting a plurality of shock absorbing members into the interior of the middle window and the gap between these members is the horizontal direction of the shock absorbing member by weight. The object of the present invention is to maximize the shock absorbing function by providing a space capable of absorbing expansion.

Another object of the present invention is to provide an intermediate window having a pressure-sensitive effect by applying a constant pressure to the bottom of the foot by an impact absorbing member inserted into the intermediate window.

10: middle window 12: lower body

12a, 12b, 12c: receiving space 14: upper body

a: rubber ball

The present invention for achieving the above object, the lower body 12 having at least one or more receiving spaces (12a, 12b, 12c) is formed in the upper opening, and receiving the lower body 12 A plurality of rubber balls (a) inserted into the space part and having a shock absorbing property are attached to the upper surface of the lower body 12 into which the rubber balls (a) are inserted, or when manufacturing shoes, that is, attaching the upper part and the window part. Combination is possible without using an adhesive in the process, the upper surface is composed of the upper body 14 made of a shape corresponding to the curved shape of the sole, the vertical load applied to the expansion and contraction of the rubber ball (a) in the horizontal direction The technical gist of the present invention is to provide a shoe midsole in which shock absorption is achieved.

Therefore, according to the present invention, there is an advantage that the shock absorbency is increased and the acupressure effect by the rubber ball.

Hereinafter, with reference to the drawings showing a preferred embodiment according to the present invention will be described in more detail.

Figure 2 is a perspective view of the middle window is mounted rubber ball according to the present invention, Figure 3 is a cross-sectional view A-A of FIG. As shown, the middle window 10 is equipped with a rubber ball (a) according to the present invention, the outer shape has the same shape as the conventional middle window (1), but the combination of the upper body 14 and the lower body 12 Is done. That is, the lower body 12 is formed with receiving spaces 12a, 12b and 12c, respectively, and a plurality of rubber balls a made of elastic material are inserted into the receiving spaces 2a, 12b and 12c. Then, the upper body 14 is coupled to the upper surface of the lower body 12 into which the rubber ball a is inserted to form the middle window 10.

On the other hand, the upper surface of the upper body 14 is a portion in contact with the sole, it is formed to correspond to the shape of the sole of the contact. That is, the shape of the bottom of the foot is a three-dimensional shape consisting of a curved curve rather than a full plane, so that the front portion where the toes are located and the rear portion where the heel is located slightly protrude. And, one side of the center portion of the sole is formed with a protrusion and the other side is to form a depression to form a more comfortable state by forming corresponding to the shape of the sole.

On the other hand, the load that the foot is applied to the ground due to the weight is through the three starting points formed on the foot. Therefore, it is preferable that each accommodation space portion 12a, 12b, 12c formed in the lower body 12 of the middle window 10 is formed at positions corresponding to the three starting points.

The accommodation space portion has a first accommodation space portion 12a in contact with the toe portion of the three starting points. In addition, there is a second accommodation space portion 12b in contact with the protrusion on the left side of the center portion of the midsole 12, and a third accommodation space portion formed in the lower region of the midsole 12 and in contact with the heel portion. There is (12c).

In addition, each of the receiving spaces 12a, 12b, 12c is filled with a plurality of rubber balls (a). Since the rubber ball is in the shape of a sphere, a constant gap 16 exists between the rubber balls a filled in the respective receiving space portions 12a, 12b, and 12c.

After the rubber balls a are filled in each of the accommodating spaces 12a, 12b, and 12c, the upper body 14 is attached to the upper surface of the lower body 12. The rubber ball (a) is not bonded to the surface of the upper body because the upper body 14 is attached with an adhesive (not shown) on the remaining portions except for the surface facing the respective receiving spaces (12a, 12b, 12c). .

Hereinafter, the operation and effects of the present invention having the configuration as described above will be described.

First, in most shoes, the insole (not shown) is located on the upper surface of the midsole 10. When shoes are worn, the load on the body is applied to the insoles through the feet. The load applied to the insole is transmitted to the midsole 10 and is applied to each receiving space portion 12a, 12b, 12c of the midsole 10. Since each receiving space portion 12a, 12b, 12c of the middle window 10 occupies most of the space of the middle window 10, the load applied to the middle window 10 is mainly applied to the receiving space portions 12a, 12b, 12c. do. Therefore, the load is transmitted to the plurality of rubber balls a inserted in the accommodation spaces 12a, 12b, 12c. Due to the load applied to the filled rubber ball a, the rubber ball a is compressed in the vertical direction, i.e., vertically downward under the load, and elastically expands in the horizontal direction, i.e., in the horizontal direction to disperse the applied load. do. By the way, since the rubber ball a is a perfect sphere, there is a gap between each rubber ball a. Therefore, the gap between each rubber ball a in the receiving space portions 12a, 12b, 12c sufficiently accommodates the lateral expansion of the rubber ball a. That is, the expansion of the rubber ball (a) by the load applied to the rubber ball (a) can be made sufficiently within the limit that its elasticity allows.

In the conventional middle window 10, even when the elastic material is used, since the inside of the material is concentrated without a gap, the expansion space inside the material due to the load is not sufficiently secured, and thus the elasticity of the material is not sufficiently exhibited.

Therefore, according to the present invention, since the expansion space of the rubber ball (a) is secured between the rubber balls (a) filled in each of the receiving space (12a, 12b, 12c), the shock absorbency is much higher than that of the conventional middle window (10) To become better.

In addition, since the rubber ball a is in the shape of a perfect sphere, when the foot comes in contact with the rubber ball a filled in each of the receiving spaces 12a, 12b, and 12c, there is also an effect of acupressure. That is, the rubber ball (a) is contracted and expanded according to the applied load, and a constant pressure is applied to the sole of the foot. Accordingly, the bottom surface of the foot in contact with the rubber ball (a) exhibits a constant acupressure effect, which causes walking. It becomes even more noticeable.

As described above, according to the present invention, there is an effect that the shock absorption is excellent due to the gap between the rubber ball can be absorbed expansion of the rubber ball by filling the rubber ball to form the receiving space portion inside the middle window, unlike the prior art.

In addition, the elasticity of the rubber ball due to the contraction and expansion action of each rubber ball is transferred to the bottom of the foot, thereby providing another effect that the sole surface is acupressure.
