Shock Absorber for Shoes {Air bag for shoes}

The present invention relates to a shock absorber for shoes, and in particular, consisting of a front air chamber and a rear air chamber filled with a certain volume of air, and an air flow path connecting the front air chamber and the rear air chamber, alternately acting 1. A shock absorber for shoes in which the front and rear air chambers alternately contract and expand by the wearer's forefoot and rear foot pressures, the upper surface of any position of the air passage or the inner surface of any position of the air passage. A pressure control plate of an elastic material positioned at any one selected from among; Pressing means for adjusting the amount of air flowing through the air flow path by pressing the pressure control plate with a constant force; It relates to a shoe shock absorber comprising a.

Shoe is an article worn to protect the foot from the outside environment, one of the main functions of the shoe is to absorb and mitigate the external shock transmitted to the foot. In order to secure a more improved cushioning function in shoes, the material or structure of the shoe window is composed in combination, or use a shock absorber as a separate part. The method of changing the material of the double shoe window or securing the enhanced cushioning function as a complex structure has certain limitations. Therefore, researches on the method of enhancing the cushioning function by embedding the roots cushioning device in the shoe are active.

A commonly used shock absorber has a configuration in which air is filled in a single closed space to repeat contraction and expansion according to the weight transfer process of the wearer. The method of embedding in the rear of the shoe window is mainly used. By the way, a number of separate shock absorber configurations have been proposed by analyzing the process of sequentially transferring the wearer's load out of the configuration of such a conventional shock absorber. Examples of such techniques are Korean Patent Publication No. 2006-0133285 and Korea Registered Patent number 0941588.

Korean Patent Laid-Open Publication No. 2006-0133285 discloses an operation configuration in which air is circulated to a plurality of internal spaces separated through a plurality of air passages when a wearer's weight acts as an air pumping unit, and Korean Patent No. 0941588 discloses a connection passage. After refilling the air chamber of any one selected from the two air chambers connected by the air, the air chamber is repeated to the operation configuration in which the air chamber alternately contracts and expands in accordance with the weight transfer order of the wearer.

The above techniques can be expected that the cushioning function can be naturally exerted by the weight delivered by providing a cushioning space at a plurality of locations in which the wearer's weight is primarily delivered and interconnecting them. However, these techniques do not involve any additional means in the air flow paths interconnecting these spaces, except that the buffer spaces are operated separately, so that the pressure of the wearer when the weight of the wearer is transferred to the buffer space The air filled in the buffer space easily escapes to the other buffer space in a very short time, and thus there is a problem in that the originally intended buffer function cannot be expected.

Preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. In describing the embodiments of the present invention, those having no direct relation to the technical features of the present invention or those skilled in the art to which the present invention pertains, and parts that may be overlapped in each embodiment may be used. Detailed description thereof will be omitted.

1 is a schematic overall configuration diagram of a shock absorber for a shoe as an embodiment according to the present invention. As disclosed in the drawings, the cushioning device for shoes according to the present invention is basically provided at the front air chamber 10 and the rear air chamber 20, the air flow path 30, and any point of the air flow path 30. It is characterized by including the air flow rate adjusting means (A). Reference numeral 1 is a window in which the shock absorber is mounted according to the present invention, and may be any one of an insole, a midsole, and a sole.

Each of the front air chamber 10 and the rear air chamber 20 is a portion to which the weight delivered through the forefoot and the back of the wearer acts, and a predetermined volume of air is filled therein, and the wearer is sequentially delivered. Given that the air charged in each interior space must flow in one direction depending on the weight, it is preferable to fill the air in the range of 40% to 80% of the volume of the interior space rather than filling all the interior spaces with air. . It is obvious that the shapes of the front and rear air chambers are completely arbitrary.

The air passage 40 is a passage when air filled in the front air chamber 10 and the rear air chamber 20 flows in one direction. The shape of the air flow path may be variously changed depending on the case, it may be formed of a plurality of different from the disclosed as well as in this case it will be apparent that the air flow path is also designed to change correspondingly.

The air flow rate adjusting means (A) is provided at any point of the air flow path 30, and a means for appropriately controlling when the weight of the wearer is suddenly delivered and the air flows in one direction at once, the pressure regulating plate and the pressing means It consists of. The pressure regulating plate may be located at any one point selected from an upper surface of an arbitrary point of the air channel or an inner surface of any point of the air channel as a means for controlling the flow of air flowing through the air channel. The pressurizing means is a means for pressing the pressure regulating plate with a constant force, whereby the amount of air flowing inside the air flow path is controlled.

Figure 2 shows a schematic configuration of the air flow control means as an embodiment according to the present invention, the pressure control plate 110 is located on the upper surface of any point of the air flow path, the pressure control plate 110 is a constant force The configuration of the pressing means 140 for pressing is disclosed.

The pressure control plate 110 adjusts the amount of air flowing in the air passage by applying a constant pressure to the air passage while contacting the air passage 30. The shape of the pressure regulating plate 110 may be variously changed, but in order to evenly transmit the external pressure to the respective portions of the air flow path, it is preferable that the pressure control plate 110 be configured to properly correspond to the shape of the air flow path 30. In addition, in view of the fact that the air flow path material of the conventional shock absorber is made of a smooth film, it is preferable to configure the material of the pressure regulating plate with an elastic body in order to improve the adhesion with the air flow path.

The pressure means 140 is a means for applying a predetermined force to the pressure control plate 110, it is preferable that the lower plate 142 in close contact with the air flow path 30 and the upper plate 146 in contact with the pressure control plate 110. The coupling of the upper plate 146 and the lower plate 142 may be made by means such as the coupling pin 143 and the pin hole 147, as shown in the figure, this coupling means may be changed in various ways depending on the product structure Can be. A constant pressure is applied to the pressure regulating plate by the coupling means having a predetermined height, whereby the pressure regulating plate presses the air flow path at a constant pressure.

It is preferable that the pressurizing means is made of a synthetic resin material, but the present invention is not limited thereto and does not exclude the case of selecting and using an appropriate one from various materials such as metal. However, in selecting the material of the pressurizing means, the material of the air flow path and the pressure control plate should be considered. In addition to the function of applying a constant force to the pressure regulating plate, the pressing means according to the present invention performs a function of appropriately protecting the pressure regulating plate from the external environment. That is, the pressure control plate made of an elastic body is to increase the durability of the shock absorber by preventing the durability is lowered or out of the original position due to frequent operation.

Briefly look at the operating configuration of the present invention. First, when the wearer starts walking, the air filled in the rear air chamber flows to the front air chamber through one end of the air passage as the rear surface of the shoe window contacts the ground first and the weight of the wearer acts on the rear air chamber. (FIG. 2 a). The front end portion of the air flowing naturally into the front air chamber by a certain external pressure reaches a point where the pressure control plate 110 and the pressurizing means 140 are provided and can no longer flow naturally. The reason why the flowing air is stagnant is because the pressure regulating plate 110 presses a portion of the air flow path 30 at a predetermined pressure, thereby reducing the cross-sectional area of the air flow path through which air can flow.

In this state, if a constant external pressure is continuously applied, the flow force of the front end of the stagnant air becomes larger than the pressure of the pressure regulating plate. Accordingly, the cross-sectional area of the reduced air flow path is sequentially restored to allow the air to move to the front air chamber. do. Next, when the front of the bottom of the shoe window is in contact with the ground, the weight of the wearer acts on the front air chamber, so that the air charged in the front air chamber moves to the rear air chamber through the air passage, wherein the air is operated as described above. The principle is filled from the front air chamber to the rear air chamber via the air passage.

That is, due to the presence of the pressure regulating plate and the pressurizing means according to the present invention, the air stagnated in the air flow path does not rapidly pass through the air flow path and is not charged to the front air chamber, and the air flows gradually in a relaxed state and the air flows gradually. To pass through, due to this technical feature the present invention is able to exhibit a more enhanced buffer function than the prior art. Unlike the disclosed, the pressure control plate according to the present invention can be located on the inner surface of the air flow path as described above, in which case the upper and lower plates of the pressing means are in close contact with the outer surface of the air flow path where the pressure control plate is located. do. Further, in order to prevent the pressure regulating plate from flowing on the inner surface of the air passage, a portion of an adjacent portion of the air passage in which the pressure regulating plate is located may be joined. Even when the pressure regulating plate is located on the inner surface of the air flow path, the operation configuration is obviously the same as the above-described embodiment, and description thereof will be omitted.

Figure 3 shows as a configuration of the pressing means of the shock absorber for a shoe as another embodiment according to the present invention. In detail, the upper plate 156 has a flat plate shape, and the lower plate 152 has barrier ribs 153 formed on both sides thereof, and a locking end 154 is provided on each of the barrier ribs. An air flow path is positioned inside the lower plate 152, and both side portions of the upper plate 156 are hooked ends 154 of the lower plate 152 in a state in which the pressure control plate and the upper plate 156 are sequentially positioned above the air passage. It is a structure that is fixed to it. The pressure regulating plate is subjected to a constant pressure by the coupling structure of the upper plate and the lower plate, and transmits the pressure to the air flow path. The operation configuration of this embodiment is also similar to the above-described embodiment, and a detailed description thereof will be omitted.

Figure 4 shows the configuration of a shock absorber for a shoe as another embodiment according to the present invention. In this embodiment, through holes 42 and 122 are formed in the air passage 40 and the pressure regulating plate 120, and the through end 163 and the coupling hole 167 in the upper plate 166 and the lower plate 162 as pressing means. ) Is a technical feature that is formed. The through end 163 is coupled to the coupling hole 167 of the upper plate in a state of being inserted through the through holes of the lower plate and the air flow path. As the through end is coupled with the coupling hole of the upper plate, the upper plate and the lower plate are integrated while maintaining a predetermined interval, and thus the pressure regulating plate positioned between the upper plate and the air passage presses the air passage with a constant force.

In the drawing, when the through end 163 is forcibly inserted into the coupling hole 167 having a relatively narrow width, the width is reduced while the through end 163 is inserted into the coupling hole 167 and the insertion is completed. A specific example of the through stage restored to its original state is disclosed. However, it is apparent that the present invention can be modified in various ways. Reference numeral 44 is a junction around the air flow passage through hole 42, and is to prevent air flowing through the air flow passage from leaking to the outside through the through hole. Bonding can be performed by any choice from a variety of ways well known in the art, such as thermal compression.

Figure 5 discloses a configuration of the pressing means of the shock absorber for a shoe as another embodiment according to the present invention. Specifically, the pressing means of this embodiment is similar to the above-described embodiment in that the upper plate 176 is provided with a coupling hole 177 and the lower plate 172 is provided with a through end 173, but provided in the lower plate The width of the through end is different from the above-described embodiment in that the width of the through end may be smaller than the coupling hole provided in the upper plate. In this embodiment, an additional configuration is required in order to prevent the upper plate 176 from being separated from the lower plate 172 while the through end 173 is inserted through the coupling hole 177. 173) proposes a structure that can rotate by a certain angle.

That is, when the through end is rotated by a predetermined angle (for example, 90 °) in a state where the through end is inserted into the coupling hole, the through end is shifted by a predetermined angle from the coupling hole, so that both can maintain the coupling relationship. If the height of the penetrating end is properly determined in consideration of the thickness of the air flow path and the pressure regulating plate located therein, it is obvious that the penetrating end can be easily maintained in engagement with the coupling hole even when an external force is applied. The rotating configuration of the through end is a technique well known in the related art, so a description thereof will be omitted.

Figure 6 shows the configuration of a shock absorber for a shoe as another embodiment according to the present invention. In this embodiment, the through-holes 52 and 132 are formed in the air flow path 50 and the pressure regulating plate 130, and the through-hole 187 is provided in the upper plate 186 as the pressing means. Similar to the example, but the lower plate 182 as the pressing means is provided with a through hole 183 and the through end 192 independent of the lower plate 182 is coupled to the fixed plate 196 independent of the upper plate 186. In this respect, there is a distinguishing feature from the above-described embodiment.

That is, the coupling portion 193 of the penetrating end is coupled to the coupling hole 197 of the fixed plate located at the upper portion of the upper plate in a state where the coupling portion 193 is inserted through the lower plate, the air flow path, the pressure regulating plate, and the upper plate. Moreover, the present invention does not exclude the case where the outer peripheral surface of the engaging portion 193 of the through end is formed in a thread shape, in which case it is possible to adjust the pressure applied by the pressing means within a certain range according to the coupling depth of the engaging portion. You lose.

If the outer circumferential surface of the coupling portion 193 has a thread shape, it is obvious that the inner circumferential surface of the coupling hole 197 should also have a thread shape. In this embodiment, the amount of air flowing through the air flow path varies depending on how much the thread and the engagement hole are engaged (depth), so that the wearer can appropriately control the degree of cushioning according to his / her movement state. To help. Unexplained reference numeral 54 denotes a joint formed around the air flow path through hole 52.

In the above description, but limited to the preferred embodiments of the present invention, but this is only an example, the present invention is not limited to this may be modified and carried out in various ways, and further technical features based on the technical spirit disclosed It will be apparent that it can be implemented in addition.
