Description

Shoes with cushioning function {A SHOES HAVING A SPECIFIC FUNTION OF CUSHION}

The present invention relates to a shoe having a shock absorbing function, and is applied to shoes of various uses, such as walking, breaking, running, climbing, and daily walking, in which the shock absorbing effect caused by stepping is improved. It is about giving.

Recently, it is widely known that walking is beneficial to health, and students and workers tend to increase walking volume, and shoes of various configurations and forms are produced and produced according to this trend.

In the case of walking, in order to increase the foot muscle strength and increase the effect of aerobic exercise, the shoe is deformed on the shape of the heel, the shoe composed by rounding the bottom, and the spring is provided between the insole, the midsole, and the sole of the shoe to absorb shock. Provided shoes, etc. are conceived.

However, the impact of repeated stepping is applied along with the exercise effect of long-term walking, which adversely affects joints or muscles. There is a need for shoes with a configuration that increases and absorbs repeated impacts by stepping.

In addition, a shoe having a plain shape in appearance is required so that the floor can be used for commuting as well as a shoe with a unique configuration and shape such as a rounded jeans, which is designed for walking.

A number of shoes having been made in this regard are designed and applied and known in advance to provide a cushioning means.

In particular, a shoe that provides shock absorption by arranging a spring between an insole, a midsole, and an outsole of a shoe has been disclosed in various configurations as a myriad of prior applications.

For example, Patent No. 10-1035380, 'Spring buffer shoes', Korean Patent No. 10-0973724, 'Shoe cushioning members', Korean Patent No. 10-1164112, 'Shock buffer shoes and its manufacturing method', Korean Utility Model Registration 20- Registered Korean Utility Model No. 0150995, Pumping Assembly for Ventilated Shoe, Korea 'Shoe Shock Absorbing Pad Structure' No. 20-0361981 Korea

Many patents, such as shoes having a shock absorption function of Patent No. 10-0937229 and 'shock absorbing shoes' of Korean Patent No. 10-0757206, are reproduced.

In particular, among the above-mentioned sources, in particular, the shoes having a shock absorbing function of Korean Patent No. 10-0937229 are generally claimed as a right to include a plurality of coil springs having a small diameter in the core of the shock absorbing pad in a shoe with a spring. And, 'shock absorbing shoes' of Korean Patent No. 10-0757206 discloses that the elastic spring made of a coil spring separately manufactured and inserted into the shoe.

In addition, the 'shock absorbing shoes' of the Korean Patent No. 10-0757206 is similar to the configuration of the spring of the elastic pad of the front and back of the shoe bottom in the configuration of Korean Utility Model No. 20-0361981, separately configured elastic pad By excavating a plurality of small diameter coil springs,

The Korean Utility Model No. 20-0361981 also discloses to provide elastic pad bodies of coil springs, which are elastic means in the front and rear of shoes, and the elastic coils are disposed on both the front and rear of the shoe bottom. Esau is a well known composition.

However, Korean Patent No. 10-0937229, 'Shoes having an impact absorption function' is a configuration in which a coil spring having a small diameter is embedded in a core of a cushioning elastic pad in a shoe having a spring.

Incorporating many small diameter coil springs into the front of the shoe, ie the front of the shoe, which is subjected to repeated impacts, is very difficult in the manufacturing process, and is likely to protrude into the sole of the user, which is a relatively soft material. There is a risk of causing injuries and injuries to the soles, and the height of the soles is deformed because the height of the coil springs must be consistently ensured in disposing a plurality of small diameter coil springs in the front to give a constant elastic force. As a result, the product quality is lowered and it is unreasonable to be applied to daily use.

The shock absorbing shoe of Korea Patent No. 10-0757206 is manufactured by separately preparing two elastic coils of coil springs and inserting them into the shoes, but since the separate elastic bodies are made independent by the guide means, they must be inserted and fixed in the shoes. There was a problem that the manufacturing process is increased and production costs are rising.

In addition, in Korean Utility Model No. 20-0361981, the elastic springs of the coil springs are provided on the front and the rear of the shoes, and the problem of the configuration of the use of these coils is that the coils with repeated expansion and contraction have a considerable height in order to provide sufficient elastic force. It becomes difficult to apply to everyday shoes,

Exposing a large number of coil springs on the front of the shoe is very difficult in the production process, and there are problems such as a small diameter of the coil spring protrudes into the insole, causing pain in the sole of the foot during repeated use.

In view of the problems of these crews, the present invention provides a resilient force to both the front and rear ridges of the front sole of the shoe and the walking and running of the shoe in the same way as the effect of the conventional crew. To minimize the application of the impact of the foot.

In addition, by providing an improved elastic means, it is possible to minimize the height of the foot portion and the bottom of the entire shoe even in shoes for everyday use, while providing a shoe that is excellent in aesthetic sense while being applied to low shoes.

In addition, the shoe according to the present invention, unlike the conventional configuration, the elastic imparting means is simple in its manufacturing process it is possible to reduce the production cost and increase the life of the shoe.

In the present invention, to solve the problems as described above,

Between the upper body, the insole which occludes the bottom of the upper body and the bottom sole, which is the bottom part, separates the midsole of the shape of the back of the foot and the cushion pad sole for forming the intermediate layer together with the midsole, so as to form the front gucci part. In the shoe having a cushioning function having a protection sole as a cover for closing between the insole and the midsole cushion pad, and having a front buffer means and a rear buffer means consisting of a spring,

The rear buffer means guides a pair of cone springs having different diameters disposed in the spring accommodation space drilled into the shoe heel of the bottom sole as a pair of stopper protrusions protruding from the bottom of the spring accommodation space. Have it,

The front cushioning means has a plurality of spring slits cut in the shoe length direction of the cushion pad sole interposed between the insole and the bottom sole, and a plurality of elastic curved parts seated on the spring slits to impart elasticity. It is a basic feature of being the leaf spring of the dog,

Among the pair of cone springs of the rear buffering means, the smaller diameter cone springs accommodated in the inner part having a smaller diameter may be I-shaped coil springs,

One or more elastic curved portions of the leaf spring of the front buffer means can be bent to adjust the elastic force is a limited optional technical component.

Shoes having a shock absorbing function of the present invention provides a new configuration of the shock absorbing means to the front and rear of the shoe, by minimizing the impact applied to the user's joints, etc. when walking, it is possible to configure the height of the shoe heel low It is possible to apply to shoes in the form of shoes, especially those that can be used in everyday life.

In addition, by improving the structure and fixing method of the spring as a shock absorbing means, it is possible to provide a configuration that can reduce the material cost and the labor cost required for production assembly.

1 shows an exemplary shape of the shoe 1 as an exploded perspective view,

Since the configuration of most shoes, sports shoes and the like is basically the same technical idea can be manufactured as shoes of various shapes and uses.

The shoe 1 includes an upper body 10 which accommodates an upper user's foot, an insole 20 that closes the bottom bottom of the upper body 10 and connects with the user's sole, and a bottom that is a bottom part. It has a sole (40).

Between the insole 20 and the bottom sole 40, the front sole of the cushion pad brush 71 is formed to form an intermediate cushion layer together with the midsole 60, which is a protective member of the back of the sole shape, and the midsole 60. Separate it to have it.

In addition, the protection sole 30 is provided as a cover for closing between the insole 20 and the midsole 60-cushion pad sole 71.

Since the insole portion 20 is in direct contact with the sole of the user, it is elastic and has good shape-maintaining material, for example, a material such as polyurethane, and has a contour (CONTOUR) suitable for accommodating the sole of the user. It is preferably molded and preferably added germanium, jade powder, nano silver powder or the like during molding to provide deodorization and antibacterial properties.

In addition, the protection brush 30 is a relatively rigid material which is cut into the sole shape and protrudes upward of the front and rear cushioning means having a lower elasticity, thereby preventing the user from harming the sole of the foot and maintaining shape. Is provided.

The bottom sole 40 formed of synthetic rubber, synthetic resin, natural resin, or the like has the sole shoe 41 integrally or separately molded at the rear foot portion, and the above-mentioned midsole 60-cushion pad sole 71 is formed. The receiving water receiving space 42 is recessed into a reduced floor shape.

As shown in FIGS. 1, 2, and 3, the shoe sole 41 has a rear buffer means 50.

In order to configure the rear shock absorbing means 50, the shoe heel 41 has a spring receiving space 43 in a columnar shape and the bottom portion 43 'as a recessed accommodation space, the spring receiving space 43 As shown in the bottom portion 43 ', a pair of cone springs 51 and 52 having different diameters are accommodated.

A pair of stopper protrusions for accommodating the small-diameter cone springs 51 and 52 inside the large-diameter cone spring 51 and for accommodating the large diameter portion below the cone springs 51 and 52 so that the position thereof does not change. 44, 45) as protruding ring-shaped protrusions.

In this configuration, a pair of cone springs 51 and 52 having different diameters protrude upward in a ring shape and are fitted to the inner diameter side of the large diameter portion of the cone springs 51 and 52 to prevent the flow of the cone springs 51 and 52. The stopper protrusions 44 and 45 which are prevented are separated and guided, and the relative movement is limited.

In order to cooperate with this, the bottom surface of the cover brush 60 may preferably have stopper protrusions 61 'and 62' for projecting downward and for receiving the small diameter portions of the cone springs 51 and 52, respectively. The cone springs 51 and 52 seated inside the space 43 are not necessarily necessary because they can be sufficiently supported by the lower stopper protrusions 50 'and 51'.

In addition, when the inner diameter of the cone spring 52 forms a shoe having a high shoe heel portion, it is of course possible to apply an I-shaped coil spring to the present invention as in the conventional art.

The main reason for forming the spring receiving space 42 in the shoe heel 41 in this manner and by using a pair of cone springs (51, 52) to facilitate the buffer is as follows.

In the case of using a single I-shaped coil spring, as in the conventional prior application, in order to withstand sufficient elastic force and the impact of repeated stepping, the height of the coil spring, whose diameter is limited to be accommodated in the shoe, must be guaranteed at least a certain amount. Therefore, naturally, the height of the heel of the shoe should be unnecessarily high, which is not desirable in general shoes and becomes inconvenient to use.

Therefore, when a pair of cone springs with different diameters are disposed as in the present invention, the elastic force can be greatly increased, and accordingly, the height of the heel can be reduced to produce shoes for various uses, and the assembly configuration is simply performed. Cost can be reduced.

Furthermore, the cone springs 51 and 52 have better shape retention compared to the I-shaped coil springs, and thus the shape of the cone springs 51 and 52 can be easily maintained even when stepping on the shoes of the user repeatedly, thereby increasing the life of the shoes.

Front cushioning means 70 for imparting elasticity to the front gingiva portion of the shoe bottom sole 40 in cooperation with the rear cushioning means 50 of the upper shoe heel 41 are shown in FIGS. 1, 2 and 4. .

In the shoe of the present invention, while providing an elastic cushioning means to the front of the shoe portion, as in the prior art, it is possible to solve the problem of increasing the height of the shoe, and to reduce the production cost and the application to shoes of various uses .

As shown in Figs. 1, 2 and 4,

The front cushioning means 70 is a front pad portion of the sole formed between the insole portion 20 and the bottom sole 40 and cushion pad brush 71 made of a material such as silicone, urethane, etc. to impart relatively elasticity. ) And a plurality of spring slits 72 (three in the figure) cut in the shoe length direction of the cushion pad brush 71.

As shown in the drawing, the spring slits 72, which are channel-shaped in the longitudinal direction, are bent and bent at the central portion as shown in the figure, and the leaf springs 75 processed into long strap shapes to impart an elastic force are placed.

Preferably, it may have a cover plate 77 that closes the upper side of the cushion pad brush 71 in which the spring slit 72 is formed, and the cover insertion channel 77 'also corresponds to the cushion pad brush 71 corresponding thereto. It is preferable that the cover plate 77 is formed so that the cover plate 77 is small and adhered, so that the thickness of the cover plate 77 is buried by the elasticity of the cushion pad brush 71 so as to be buried. This is not necessary.

The cover plate 77 is formed of a relatively high hardness material to suppress the protrusion of the leaf spring 75 inserted into each spring slit 72, that is, the protrusion of the user's foot. It may further have a cover stopper (not shown) of the cover plate 77 protruding downward to separate and close each spring slit 72.

The leaf spring 75 has an elastically curved portion 75 'for imparting elasticity, which is bent into a roughly' s' shape as shown in FIG. 5, and the impact on the bottom surface of the bottom sole 40 by repeated impacts. Contact bending portions 75 "are formed at both ends of the leaf spring 75 so as not to be wound so that the corner portions are not directly connected to the floor. Due to the interposition of the contact bending portions 75", Both ends of the leaf spring 75 can be prevented from digging into the bottom surface of the bottom sole 40 in response to repeated up and down impacts.

The leaf spring 75 may have a '' shape, but as shown in the bottom view of FIG. 5, a leaf spring having two or more elastic curved portions 175'-1 and 175'-2 in a 'ㅆ' shape ( 175) and in this case, the elastic force is higher and the height of the elastic curved portions 175'-1, 175'-2 of the entire leaf spring 175 is reduced, so that shoes having a lower bottom can be manufactured.

In addition, if necessary, the plurality of leaf springs 75 may be a single machined leaf spring connected to each other at the side of the elastic curved portion 75 'rather than a separate leaf spring.

Although three spring slits 72 are shown in the figure, two or more spring slits 72 may be employed depending on the strength and thickness of the leaf spring 55, which is a spring provided.
