Description

Buffer structure for sole

The present invention relates to a cushioning structure of a shoe window, and more particularly, a high buffering structure is made by a simple configuration by proposing a configuration including a cushioning portion formed of a plurality of ventilation holes and a cover portion sealing the buffering portion integrally formed in the window. It is intended to provide a cushioning structure of a shoe window that can secure the function.

Shoes have been worn as a means to effectively protect the foot from the external environment. Recently, a method of manufacturing a product having various functions has been proposed and a product using the same has been released and distributed. Among the functions of the proposed or distributed product, The greatest weight is associated with the cushioning structure to mitigate the shock delivered directly to the foot.

Typically, the cushioning structure of a shoe is roughly divided into a method of using air and a method of using a foam. The former is a method in which a shoe-filled housing is mounted on a shoe to properly control the force transmitted from the outside by air pressure. If the housing material is selected properly, the device is semi-permanent by the flow of sealed air. This is the most commonly used method in the industry because it has the advantage of being able to work with other devices. On the other hand, the latter has a certain wear resistance and at the same time a foam having a restoring force of a predetermined value or more is mounted on a specific part such as the heel of the shoe, or the window of the shoe itself is composed of different materials for each part to prevent external impact. As it adopts a moderating method appropriately, there is an advantage that the manufacturing process is simpler than the electron using air.

However, in order to achieve the intended purpose, the former has to control the direction of movement of the gas without a certain direction of movement in a specific direction inside a housing having a certain shape, so that a special structure of the housing or another structure that controls the housing itself is used. There is a disadvantage that the manufacturing process is somewhat complicated, such as to be provided separately. In addition, this method has a drawback in that the structural stability is reduced by reducing the integrity of the window in that the housing is separate from the window itself, the disadvantage of the structural stability is basically a significant reduction in the damping function There is a serious problem in that it must be connected. On the other hand, in the latter method, when the shoe window itself is made of a different material for each part, the resilience of the foam is remarkably inferior when repeated use due to the characteristics of the foam. In the case of mounting in advance to any part of the window after manufacturing in advance, there is a disadvantage in that the manufacturing process is complicated and the unit price is increased in that a separate additional process is required, and it has the problem of structural stability reduction of the former method.

The present invention has been proposed to solve the above problems, and an object thereof is to provide a shock absorbing structure that can properly distribute the load of the wearer in the window itself.

Another object of the present invention is to form a cushioning structure integrally with the window to ensure the structural stability of the shoe window and to enhance the fit.

It is still another object of the present invention to provide a buffer structure that can reduce the production cost by simplifying the manufacturing process by excluding the additional device in addition to the window.

In order to achieve the above object, the present invention provides a cushioning structure of a shoe window, including a window having a cushioning portion formed by a plurality of ventilation holes penetrating the upper and lower surfaces in a predetermined area, and a cover portion for sealing the buffer portion. What is achieved is its technical feature.

The buffer part may be made of a material different from that of the window.

In addition, the vent hole of the buffer portion may be formed vertically.

In addition, the buffer unit may be formed in a plurality of spaced apart at regular intervals.

In addition, each vent hole of the buffer unit may be filled with any one or more materials selected from the material of the window and the same or different materials.

In addition, the buffer portion may be formed stepped with the surface of the window.

The cover part may be made of an elastic material.

The window may be any one selected from an insole or a midsole.

As described above, the present invention allows the cushioning structure to be integrally formed in the window itself so that the cushioning function can be secured while securing the structural stability of the shoe window.

In addition, the present invention has the advantage that the manufacturing process can be significantly reduced by simplifying the structure by integrally providing a buffer structure to the window itself without mounting an additional additional device, thereby significantly reducing the production cost.

Figure 1 is an external view of the buffer structure as an embodiment according to the present invention, Figure 2 is a cross-sectional view of the line A-A 'of Figure 1, with reference to the accompanying drawings to examine the preferred embodiment of the present invention in detail. As disclosed, the present invention basically includes a window 10 provided with a shock absorbing portion 120 and a cover portion 200 that seals a portion of the shock absorbing portion 120 of the window 10 and isolates the outside from the outside. It can be seen that there is a technical feature in that it is made. The window 10 may be any one selected from an insole or a midsole.

The cushioning portion 120 of the window 10 is a portion formed by densely ventilating holes 122, it is preferable that the window 10 is provided in any portion that requires a cushioning function, the buffer portion is a load of the wearer Of course, it is possible to be provided at any one or more places selected from the forefoot, rear, and midfoot of the window as concentrated. In the figure, the case where the forefoot part and the forefoot part of a window is provided with the buffer part as an example is shown. On the other hand, the buffer unit 120 may be made of a material different from the material of the window 10, in consideration of the buffer function it will be preferable to be made of a material having a higher hardness than the material of the window. In other words, the material of the shock absorber is configured to have a higher hardness than other parts so as to appropriately accommodate the load of the wearer.

The vent hole 122 is preferably formed through the upper and lower surfaces of the window 10 so that a predetermined space is formed in the window 10, a predetermined amount in the inner space of the vent hole 122 The air or separate material is filled to ensure substantial cushioning function. The shape of the vent hole 122 is not particularly limited, and it is completely arbitrary whether or not the area of the buffer 120 is to be concentrated. Given that the load of the wearer typically acts perpendicular to the surface of the window, it is desirable to allow vent holes 122 to be formed perpendicular to the surface of the window 10, as shown in FIG. Will do. However, as described above, when the material of the buffer unit 120 is composed of high hardness and a separate filler is embedded in the vent hole 122, the vent hole 122 may be formed even if it is not formed vertically. This will be described later.

The cover part 200 is a means for sealing the shock absorbing part 120. The cover part 200 adds a certain amount of air or fillers present in each of the vent holes 122 of the shock absorbing part 120. Can act as a buffer. Considering that the shock absorber 120 may vertically move at a predetermined distance up and down as the load of the wearer acts, the cover 200 is preferably made of an elastic material. Of course it does not limit.

The present invention does not exclude the case where the buffer portion is formed to protrude from the surface of the window, an example of which is disclosed in FIG. 3. That is, when the buffer unit 140 is formed to protrude upward from the surface of the window 10, as shown in FIG. It is preferable to enclose and seal the site). 3 illustrates a case where the buffer portion is formed at a predetermined vertical height on the surface of the window, but this is merely an example, and the present invention does not exclude a case in which the buffer portion is formed in a form naturally corresponding to the curvature of the sole. to be.

Meanwhile, FIGS. 5 and 6 each disclose a shock absorbing part as another configuration of the present invention, and what is disclosed in each drawing assumes that the shock absorbing part is provided in each of the forefoot part and the forefoot part of the window as in the case of FIGS. 2 and 4 described above. The case shows the cross-sectional structure of the rear foot. First, FIG. 5 shows a case in which the vent hole 162 is formed perpendicular to the surface of the window 10 and is formed at an angle. The inclination angle of the vent hole formed in accordance with this embodiment is not particularly limited and may be variously changed depending on which specific portion of the window 10 is formed in the buffer unit 160.

FIG. 6 shows a configuration in which a separate filler 190 is filled in an inner space of each of the ventilation holes 182 formed in the buffer unit 180. The filler 190 may be made of any one or more materials selected from the same or different materials and the material of the window 10, which may of course include not only liquid, but also formed of any shape. . When a separate filler is added according to this embodiment, it is apparent that the buffer function of the buffer unit 180 may be doubled.

In the above, the above-described embodiments are limited to the preferred embodiments of the present invention. However, the present invention may be variously changed or modified, but only by way of example. The true scope of the present invention should be determined by the technical spirit described in the claims. .
