Description

Shoe having impact absorption power and pushing function}

The present invention relates to a functional shoe, and more particularly, a spring member is installed at the rear portion of the shoe sole, and a shiatsu protrusion is formed at one side of the middle portion to absorb shock by the spring member and to prevent foot flatness by the acupressure protrusion. The present invention relates to a shoe having a function and having excellent appearance in shock absorption and acupressure.

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. The shoe has an upper portion covering the instep portion and a window portion forming the bottom and making contact with the sole. In particular, the sole is in contact with the ground, which is required to be abrasion-resistant and non-slip, such as the sole of the sole, the midsole is located in the upper part of the sole and the shock absorbing function is important, and the insole in contact with the foot of the human body There is this.

Today, a lot of shoes have been released to give these shoes a variety of functions for the health of the human body, and strive to give more improved functions. For example, since the impact transmitted to the foot by the weight when walking is very large, efforts are being made to improve the shock absorbing function of the shoes regardless of the type of shoes. This is a great deal of research on soles in line with efforts to improve the shock absorbing function of shoe soles.

In general, the sole is molded to have the same curvature as the bottom of the human foot by giving a low specific gravity and elasticity by foaming the polymer material through a press or an injection machine. Thus, the function of shock absorption of the sole depends on the elasticity exhibited by the material itself and the microscopic spaces present in the material. In order to improve the shock absorbing function of the sole which is dependent on the elasticity of the material itself, a lot of research and development has been made on the material development of the sole. Today, various kinds of materials have been developed or adopted and used as the sole material. .

However, relying on the material itself for the shock absorbing function of the sole has the following problems.

The material used for the sole is a urethane or a single foam such as 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 sole has a certain shape, and the inside and the outside are filled with tangible materials. When the shoe is in contact with the ground while it is worn, the sole is loaded by weight. In order for the sole to have a shock-absorbing function, the predetermined volume of the sole that expands in the transverse direction (horizontal portion) maintains the shape of the sole when the sole is applied vertically, ie, vertically downward by the foot. It must have the property of resilience, moving to another part of the sole and then returning.

However, since the sole material has a certain shape and the entire inside and the outside are filled with tangible materials, it is limited to move the predetermined volume of the sole to other parts of the sole with respect to the load within the predetermined shape of the sole, which is sufficient for external impact. There is a problem that the shock absorbing function can not be.

In addition, in recent years, the development of a traffic culture reduces the absolute walking distance of people, causing a variety of problems, in particular has a problem that the soles are flat feet. Of course, shoes with acupressure function have been released by forming a plurality of protrusions on the sole of the shoe, but these shoes have acupressure function on the entire sole of the foot, and the effect is not excellent, and it does not help to solve the flat feet at all. There is a problem.

Accordingly, the present invention is to solve the above problems, to supplement the shock absorbing function on the back portion of the most impacted shoes, providing a shoe that can intensively pressure the concave portion of the middle side of the sole shock absorbing function An object of the present invention is to provide a shoe with an anti-flat foot function.

Another object of the present invention is to provide a shoe that exhibits a unique aesthetic by forming a shoe so that the back portion of the shoe flows up and down as it is exposed to the outside each time it is walking.

In addition, it is another object of the present invention to provide a shoe that improves quickness during athletic play, such as running help due to the cushioning action of the back of the shoe.

And it may be installed around the outer periphery of the locking projection body, and may further include an auxiliary member for stopping the contraction of the intermediate window spans the upper surface of the outsole and the locking jaw end of the guide groove.

Therefore, according to the present invention, acupressure is simultaneously applied to the shock absorber and the sole recess during use of the shoe, which is beneficial to health.

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

1 is a side view of a shoe according to the present invention. As shown, the present invention consists of the sole 10, the midsole 20 and the upper portion of the upper 30. The sole 10 is formed to be flat throughout, and the upper protrusion rib 12 protruding upward from the rear end is formed. In addition, the middle window 20 is formed in the front portion is flat and inclined in the upward direction toward the rear side, the lower protrusion rib 22 is formed to protrude to the rear end. Only the front part of the sole 10 and the midsole 20 are bonded by the adhesive (a), and the rear part remains unbonded. Therefore, a constant space is formed at the rear of the sole 10 and the middle window 20, and the intermediate window 20 is provided with a septum buffer 40, a guide 50, 60, and acupressure 70 in the space. This flows up and down. Then, the upper 30 is connected to the midsole 20 to form a whole shoe.

Next, with reference to the drawings of Figures 2 to 5 will be described in more detail the shock absorbing portion 40, the guide portion 50, 60 and the acupressure portion 70 according to the present invention. First, the shock absorber 40 will be described. The shock absorbing portion 40, by using the elastic force of the spring, so that the support protrusion 42 is formed in the center portion of the rear upper surface of the sole 10, the coil spring (to the outer circumferential surface of the support protrusion 42) 44) to wrap. In addition, the lower side of the intermediate window 20 at a position corresponding to the support protrusion 42 is formed downwardly and a restricting groove 46 is formed in the inner side, so that the support protrusion 42 having the coil spring 44 audited therein is formed therein. To be inserted. Therefore, in the state that the impact is not applied, the coil spring 44 has a length that extends as much as possible, and when the impact is applied, the coil spring 44 is compressed along the restricting groove 46 to absorb the impact. .

Next, the guide parts 50 and 60 will be described. The guide parts 50 and 60 are intended to uniformly expand and expand the entire shoe surface when the spring 44 of the shock absorbing part 40 is compressed and inflated by an applied shock. It consists of a front guide member 60 formed in the front of the rear guide member 50 formed in the rear. That is, when the rear guide member 50 is described first, the length of the support protrusions 42 is slightly longer than the support protrusions 42 on both sides, and the locking protrusion 52 is provided with the protruding jaw 52a on the upper outer circumferential surface thereof. ) Is formed. The locking protrusion 52 is inserted into the bottom surface of the intermediate window 20 at a position corresponding to the locking protrusion 52 to move up and down, and a locking jaw 54a corresponding to the protruding jaw 52a is formed at a lower end thereof. The guide groove 54 is formed to prevent the separation of the locking projection 52_ is formed to form a rear guide member 50 to maintain the left and right balance of the rear of the shoe. Even if the up and down flow is made, the locking jaw 52a is supported by the protruding jaw 54a so that the separation of the intermediate window 20 is prevented.

Meanwhile, circular guide protrusions 62 and 70 are formed at both front sides of the support protrusion 42. The heights of the guide protrusions 62 and 70 are different from each other, because the high guide protrusions 70 among the guide protrusions 62 and 70 have a function of the acupressure part 70 to be described later. A front guide member 60 is formed at the bottom of the intermediate window 20 at a position corresponding to the guide protrusions 62 and 70, and the guide protrusions 62 and 70 are inserted into the front grooves 64 to move up and down. Therefore, the guide windows 50 and 60 are provided at both front and rear sides of the shock absorber 40, respectively, so that the intermediate window 20 can be vertically flown in the same plane without twisting from side to side.

Next, the acupressure unit 70 will be described. One side of the guide protrusion 70 forms an acupressure part 70. That is, as shown in Figure 4, when the user wears the shoe when the guide projection 70 of the portion where the concave groove of the sole is located to be formed somewhat longer in the vertical direction during the contraction of the middle window 20 by the load The end portion of the guide protrusion 70 constituting the acupressure portion 70 is to press the recessed groove portion. Then, the upper end of the guide protrusion 70 constituting the acupressure part 70 to form a round circle so that the pressure on the sole concave groove smoothly. Therefore, the acupressure part 70, as described above, serves as a guide for the shock absorbing part 40, and has a pressure function of the concave groove of the sole.

In addition, the contraction of the shoe is regulated by the protruding ribs 12 and 22 formed at the rear ends of the sole 10 and the midsole 20. That is, upon contraction, contraction is made to a portion where both end surfaces of the protruding ribs 12 and 22 touch first.

On the other hand, unlike normal walking, there is a case where shrinkage expansion should not be performed. In this case, an auxiliary member 80 is provided to prevent contraction and expansion of the shock absorber 40. That is, as shown in FIGS. 6 and 7, the auxiliary member 80 is detachably formed on the outer circumferential surface of the support protrusion 52. The vertical height of the auxiliary member 80 is configured to extend from the upper surface of the sole 10 to the lower surface of the locking projection 54a of the regulating groove 54, and is fitted to be coupled at both sides of the body of the support protrusion 52. The auxiliary member 80 has a semi-circular groove 86 corresponding to the body of the support protrusion 52 is formed on the inner side, the protruding pin 82 is formed on the intermediate surface of the one side auxiliary member 80, the other auxiliary member The pin groove 84 is formed on the middle surface of the 80. Therefore, when the auxiliary member 80 is coupled, the protruding pins 82 are fitted into the pin grooves 84, and in this state, the shoes are not contracted.

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

8 is a view showing a state of use. As shown, when the user walks wearing shoes, an impact is applied. At this time, the contracting action of the spring 44 occurs by the applied vertical load. The contraction of the spring 44 is made in the restricting groove 46, and the downward movement of the middle window 20 according to the contraction is a constant direction by the support protrusion 42 and the guide portion (50, 60) Is done only with Therefore, even when more load is applied to a specific position, the entire surface of the middle window 20 is evenly contracted in the downward direction, so that the impact applied is evenly distributed, thereby minimizing the adverse effect on the user.

On the other hand, the intermediate window 20 is contracted and at the same time the guide protrusion 70 constituting the acupressure portion 70 is to press the concave groove of the sole. That is, since the guide protrusion 70 constituting the acupressure part 70 has a longer vertical length than the other guide protrusion 62, the end portion of the acupressure part 70 is concave to the sole through the insole provided inside the shoe. The groove will be pressed.

And, when the foot falls to the ground there is no load applied to the coil spring 44 of the shock absorbing portion 40 is inflated by its elasticity, thereby the middle window 20 is lifted upwards . On the other hand, when the middle window 20 is lifted to the upper portion, the projection jaw 52a of the locking projection 52 is caught by the locking jaw 54a of the restricting groove 54, which is no longer lifted upward. Will be blocked. Therefore, the contraction and expansion of the middle window 20 is repeated for each step for walking, and the pressure is reduced by the pressure of the sole concave grooves by the acupressure unit 70 at each contraction, so that the impact is much reduced, and more comfortable walking by the pressure of the sole Will be able to.

On the other hand, in order to avoid climbing or climbing a rock wall or the like is to use the auxiliary member 80 provided separately. That is, the auxiliary member 80 is coupled to the outer circumferential surface of the body of the locking protrusion 52 to walk. The auxiliary member 80 is in close contact with the upper surface of the sole 10 and the lower surface of the locking jaw 54a of the restricting groove 54, so that the contraction of the shoe does not occur even when a force is applied in the vertical downward direction. Therefore, in this case, the auxiliary member 80 serves as a kind of heel heel to increase the height of the height. Unlike the above, in order to walk normally, the auxiliary member 80 is separated and stored separately so that the shock-absorbing and acupressure functions can be performed again.

As described above, the shoe according to the present invention has the effect that the pressure absorbing as well as the sole concave groove pressure at the same time by pressing the sole concave groove at the same time as the contraction and expansion by the applied load.

And, since the contraction and expansion is not made using the auxiliary member provided separately, there are other effects that can be used for various purposes as necessary.

In addition, as the site of contraction and expansion of the midsole is exposed to the outside as it is externally recognizable, there is another advantage that creates a unique new aesthetic as a change in the shape of the shoe according to the shrinkage expansion.
