Description

Shoe with the function of shock absorption and airing

The present invention relates to a shock absorbing structure of the sole that is applied to the shoe, and more particularly to the shock absorbing structure of the shoe sole is secured breathable to use the elasticity of the spring and rubber but the air supply is smoothly into the shoe will be.

In recent years, many kinds of shoes have been manufactured to improve living standards and meet various needs of consumers. Generally, a shoe is composed of a sole and an upper coupled to the upper part of the sole, and in particular, the sole is composed of a midsole forming the sole of the shoe and an outsole forming the sole of the shoe.

Among the configuration of the outsole as described above, the midsole is usually made of a foam-molded structure of a synthetic resin material of various materials, the outsole is made of a rubber material so as to meet the functions for wear resistance and slip, recently used as a material of the midsole As a synthetic resin, EVA (ETHYLENE VINYLACETATE), which is not only light but also absorbs shock, has resilience, and is advantageous in terms of preventing discoloration and environmental pollution, is mainly used.

The shoe to which the sole is applied as described above should be able to reduce the impact on the human body such as ankle or muscle by absorbing the impact generated during walking and dispersing effectively. Therefore, various shock absorbing structures have been proposed. For example, a shock absorbing gel is used in the midsole to impart a shock absorbing function to the sole, or a structure in which an elastic member such as an air bag or a spring is embedded.

Here, according to the shock-absorbing structure using the spring to form a space inside the sole and simply buried the spring in the space, the buried spring is moved around in the space bar, it is not fixed in place, stable shock absorption effect It was a difficult configuration to implement.

On the other hand, the inside of the shoe is always moist and maintain a high temperature by the body temperature, there was a lot of fear that the bacteria breed and smell. Therefore, in addition to the shock-absorbing structure, the structure of the sole to supply the air into the shoe to keep the interior of the shoe in a comfortable state is required.

The present invention proposes to solve the above problems as the spring can be stably contracted and expanded to effectively absorb the shock while supplying air into the shoe during walking to maintain the interior of the shoe in a comfortable state The purpose is to obtain a shock absorbing structure of the sole.

According to the present invention, the spring can be stably contracted and expanded up and down to work with elastic projections to effectively absorb shocks, and the inside of the shoes is comfortable as air is naturally supplied to the shoes during walking. You will get a shoe sole that will help you stay in shape.

The present invention is provided with a sole consisting of an upper sole and a lower sole in order to effectively absorb the shock generated during walking while supplying air into the shoe during walking to maintain a comfortable state of the shoe sole. However, a space is formed in the lower window so that the spring is disposed, and the upper window is formed by opening an air passage through which the air flows in the transverse direction and opening the upper surface, while forming an elastic protrusion in which the spring is fitted. And, the spring and the protrusion is configured to absorb the shock,

The protrusion is formed along the body from the side wall to the upper passage is connected to the air passage is formed so that the air in the space is passed through the inlet passage to the air passage is configured to be discharged into the shoe inside We propose a shock absorbing structure of the shoe sole to ensure breathability.

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 5.

1 is an exploded perspective view of each part showing the structure according to the first embodiment of the sole according to the present invention, Figure 2 is a plan view showing the structure of the sole according to the present invention, Figure 3 is a second embodiment of the sole according to the present invention An exploded perspective view of each part showing its structure.

As shown, the sole 100 according to the present invention is largely divided into the upper window 100 and the lower window 120 to form a sole 100 by being bonded to each other.

The space 122 is formed on the upper surface of the lower window 120. The space 122 is formed by the upper surface of the lower window 120 is formed, the bar is mainly formed in the portion to which the load is applied, it is usually installed in the heel portion and may be formed in the front heel portion as needed. As shown in FIGS. 1 and 3, the size of the space 122 may be adjusted according to the configuration of the spring 130 and the protrusion 112.

The spring 130 is placed on the lower window 120. Spring 130 has a suitable elasticity can be applied to one configured in a variety of shapes, but preferably applied to the wound in a hexagonal shape that can absorb shock well. In particular, the iron wire constituting the spring 130 may be applied to the plate form to stably absorb the impact.

The width of the iron wire constituting the spring 130 is 3 ~ 7mm, the thickness is used in the range of 0.5 ~ 1.5mm, the diameter is formed to be 20 ~ 60mm. If the elasticity of the spring 130 is too small or too large to fall outside the above range it is preferable to form within the above-described range because the function to absorb the impact is reduced.

The spring 130 as described above is to absorb the impact while contracting when the load is applied, and to push the foot when inflated to play a smooth walk.

The upper window 110 is bonded to the upper portion of the lower window 120, the air passage 118 through which the air flows is formed through the body in the transverse direction to the upper surface to reach the inside of the shoe. The bottom surface is formed with a protrusion 112 of elastic material (rubber, silicone, polyurethane, pylon, etc.) to which the spring 130 is fitted. The protrusion 112 causes the spring 130 to contract and expand in position.

The protrusion 112 has an inflow path 114 penetrating upward from the side wall along the body. The inflow passage 114 serves as a passage through which air is introduced from the space 122 formed in the lower window 120 to be discharged into the shoe, and an upper end thereof is connected to the air passage 118.

Therefore, when a load is applied from the upper side, the space 112 is also narrowed, and air is introduced into the inflow path 114 and then moved along the air passage 188 to be discharged into the shoe. In particular, since the inlet of the inflow path 114 is formed on the side of the protrusion 112, it is prevented from being blocked by the inner wall surface of the space 122, thereby enabling smooth air movement.

Here, the protrusion 112 is preferably formed to concave the lower end upward. When the bottom portion is concave, the load is applied from the upper side when the protrusion 112 descends, so that the bottom portion of the protrusion 112 touches the inner bottom of the space 122 formed in the lower window 120. At this time, the edge of the groove formed at the bottom of the protrusion 112 is contracted to the bottom and at the same time to support the load in the air in the concave portion.

If pressure is continuously applied, the air escapes between the bottom edge of the protrusion 112 and the bottom of the space 122 formed in the lower window 120 by the air pressure, and the protrusion 112 further increases. You will descend. The above process is possible because the protrusion 112 is made of elastic material.

If the protrusion 112 continues to descend as air escapes as described above, the groove formed at the bottom of the protrusion 112 is contracted flatly, and as a result, the load is transmitted to the body of the protrusion 112 and the protrusion 112. The whole contracts. At this time, the inlet of the inflow passage 114 formed on the side of the protrusion 112 is also narrowed, so that the amount of air outflow in the space 122 is reduced.

According to the configuration as described above, the lower edge of the initial protrusion 112 is quickly absorbed shock while contracting, while the air is compressed to support the load to prevent the projection 112 from falling sharply, then the load continues When the air reaches the critical point, the air escapes from the lower groove of the protrusion 112, and the groove is contracted flat so that the entire protrusion 112 contracts and supports the load, so that the shock can be sequentially absorbed. do.

In addition, when the load is initially applied, as the thin edge portion of the groove formed at the bottom of the protrusion 112 is first contracted, it does not significantly affect the inlet area of the inflow passage 114, and air is smoothly discharged.

After the load is continuously applied, the grooves are contracted flat and the load is transmitted to the protrusions 112, and the inlet passage 114 is also narrowed as the entire body of the protrusions 112 is contracted to reduce the outflow of the ball. In other words, the shock absorber functions as a shock absorber.

On the other hand, the sole 100 according to the present invention as described above may be implemented by varying the configuration of the protrusion 122 formed in the space 122 and the upper window 110 formed in the lower window 120. That is, the width of the space 122 is formed to be large as necessary, and then two springs 130 may be disposed in one space 122. At this time, the lower window 120 should be formed of two projections 112 so that the two springs 130 are fitted, respectively.

According to this configuration there is an advantage that can be absorbed more effectively by placing a plurality of springs 130 and the projection 112 in the heel portion is heavily loaded bar, preferably to form one in the heel portion Since the ball of the foot is wide in the front heel to form two to effectively absorb the shock. At this time, when the size of the spring 130 and the protrusion 112 is small, it is also possible to form two on the heel portion and three on the front heel portion.

Hereinafter, look at the operation of the sole according to the present invention configured as described above.

Figure 4a, 4b is a state diagram showing the action of the sole according to the present invention.

As shown, when a load is applied while walking, the spring 130 absorbs a shock while being contracted under load.

At this time, the protrusion 112 formed in the upper window 110 is also lowered, and the lower end is in contact with the bottom of the space 122 formed in the lower window 120, and when the load is continuously applied, the protrusion 112 is applied. It also absorbs shock while shrinking.

When the bottom 112 contacts the bottom of the space 122, the concave groove formed at the bottom thereof contracts while the air is trapped, and the drawing air exits to the outside of the groove to reach a critical point. Will be lost.

Therefore, before the lower end of the protrusion 112 touches the bottom of the space 122, the shock is absorbed by the spring 130 only, and the lower end of the protrusion 112 reaches the spring 130 and the protrusion 112. The shock is absorbed by the edge of the groove formed at the bottom of the spring, and then the grooves are flattened while the air escapes, so that the spring 130 and the protrusion 112 absorb the shock, thereby sequentially absorbing the shock. I will be able to give.

On the other hand, when a load is applied as described above, the space 122 formed in the lower window 120 is also contracted under the load. As a result, the air in the space 122 is introduced along the inflow path 114 formed in the protrusion 112 to be discharged into the shoe through the air passage 118.

At this time, the inflow path 114 is maintained almost completely until the first and the edge of the groove formed in the bottom of the protrusion 112 is contracted, the groove formed in the bottom of the protrusion 112 is contracted flat projection When the load is transmitted to (112) and the whole body is contracted, the inlet is narrowed while contracting together. At first, the air is rapidly discharged, and later, the amount of outflow is reduced, acting as a kind of shock absorber. It helps with absorption.

This process helps to keep the inside of the shoe in a comfortable state by continuously supplying air while being able to absorb the shock smoothly while continuously repeating when walking.

Figure 5a, 5b is an exploded perspective view showing the structure and action of each part according to the third embodiment of the sole according to the present invention.

The sole according to the present invention configured as described above may be formed by inserting the casing 140 into the space 122 formed in the lower window 120. The casing 140 has a function of supporting the protrusion 112 and the spring 130 by forming and then inserting the space 122 in a sufficient width, and a lower window 120 formed of a soft material. As the shape changes during walking, the space 122 is prevented from being deformed, thereby stably absorbing the impact. Such a casing 140 may be configured in various forms as needed, such as a hexahedral shape, a cylindrical shape.

In addition, the sponge 142 may be filled in the casing 140 configured as described above. The sponge 142 may be any one of pylon, memory foam, etc., as long as it is an elastic material having voids, and serves to prevent the spring 130 from rubbing against the meshing 140 to generate noise. Here, the sponge 142 may be filled with the carved or inserted into the pre-formed to fit the shape of the casing 140, of course, the space between the spring 130 and the protrusion 112 is wide. In this case, it can be filled in the corresponding part and can be variously modified at the technical level of those skilled in the art.
