Description

Shoe Shock Absorber

The present invention relates to a shock absorber for a shoe, and more particularly, a front air chamber and a rear air chamber, and an air passage connecting the front air chamber and the rear air chamber, and alternately acting on the forefoot and the rear of the wearer. In the shock absorber for shoes in which the front air chamber and the rear air chamber alternately contract and expand by foot pressure, the air flow passage reduces the cross-sectional area of the air flow passage when air suddenly flows in one direction. The present invention relates to a shock absorber for a shoe, in which a wearer can experience an enhanced shock absorbing effect while walking by being provided with an air passage cross-sectional reduction means capable of preventing sudden air flow.

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 more cushioning function in shoes, the material of the shoe window or its structure may be composed in a complex manner or a shock absorber may be used as a separate part. There are certain limitations, and there is a lot of research on how to improve the cushioning function by embedding the root canal buffer in the shoe.

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.

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.

The present invention has been proposed to solve the above problems, the present invention by adding a means for controlling the flow of air to a certain level in the air flow path, the air filled in a specific buffer space is quickly escaped and buffered It is an object of the present invention to provide a shock absorber for shoes that can prevent the phenomenon of deterioration.

It is another object of the present invention to reduce fatigue by continuously stimulating the wearer's foot while air is gradually released from a specific buffer space by the pressure delivered by forming a plurality of acupressure protrusions on the surface of the buffer space or its periphery.

In addition, the other end of the air flow guide plate may be equipped with a clamp surrounding the outer surface of the air flow path and the air flow guide plate at a constant pressure at the same time.

The air flow path cross-sectional reduction means may include a first coupling part formed to be coupled to the inner surface of the air flow path in a width direction except for the air flow hole, and the air flow hole may be spaced apart from the first coupling part at a predetermined interval. The second coupling part is formed to be coupled to the inner surface of the air flow path in a width direction without being small, and has a length in a range between the air flow hole and the inner width of the air flow path, and the space between the first coupling part and the second coupling part. It may consist of one-way air flow derivatives enshrined.

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 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 installed in the front air chamber 10 and the rear air chamber 20, the air flow path 40, and any point of the air flow path 40. It is characterized in that it comprises an air flow path cross-sectional reduction means 100. 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, and may be formed of a plurality of different from the disclosed.

The air flow path cross-sectional reduction means 100 is installed at any point of the air flow path 40, and is a means for appropriately controlling when the weight of the wearer is suddenly transmitted and the air flows in one direction at a time. 5 is a schematic plan view of the air flow path cross-sectional reduction means as an embodiment according to the present invention, Figure 6 is a cross-sectional view A-A 'of FIG. As disclosed, the air flow path cross-sectional reduction means 100 is coupled to couple the air flow guide plate 120 and the air flow guide plate 120 located in the longitudinal direction inside the air flow path 40 with the inner surface of the air flow path. The unit 140 may be formed.

Although the shape of the air flow guide plate 120 may be variously changed, it is preferable that the air flow guide plate 120 is formed in a film shape, and configured to be positioned in the center of the air flow path 40 by the coupling part 140. Air flowing freely through the air flow path flows through the space between the inner surface of the air flow path 40 and the air flow guide plate 120 when the air flow path cross-sectional reduction means is installed. The coupling unit 140 may be formed by simply bonding the air flow guide plate to the inner surface of the air flow path, and may be made of a conventional adhesive means.

Referring to each of Figures 7 to 9 as an embodiment according to the present invention looks at the operating configuration of the air channel cross-sectional area reduction means. When the wearer wears a shoe with a shock absorber according to the present invention and starts walking, the weight of the wearer acts on the rear air chamber while the back of the bottom of the shoe window contacts the ground first. Air filled in the rear air chamber by external pressure (body weight) flows through one end of the air passage to the front air chamber (see FIG. 7).

The front end portion of the air flowing naturally into the front air chamber by a constant external pressure reaches a point where the air flow path cross-sectional area reduction means is provided and is no longer naturally flown and stagnated (see FIG. 8). The reason why the flowing air is stagnant is because the air flow guide plate 120 and the coupling part 140 occupy a part of the cross-sectional area of the air flow path, thereby obstructing the flow of flowing air. In this state, when a constant external pressure is continuously applied, the front end of the stagnant air is sequentially pushed between the air flow guide plate 120 and the inner surface of the air flow path. In this process, the gap between the air flow guide plate and the air flow path is To some extent, the flow of air is partially improved (see FIG. 9).

However, since the expansion interval between the air flow guide plate and the air flow path is limited due to the presence of the coupling portion 140, the air stagnated in the air flow path does not rapidly pass through the air flow path and is filled into the front air chamber, but is relaxed. At constant flow, the air slowly passes through the air path. Due to the technical features of such an air flow path cross-sectional reduction means, the present invention is able to exhibit a more enhanced cushioning function than the prior art. 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. The operation configuration that occurs at the point where the air flow path cross-sectional reduction means is installed in the process of air flowing through the air flow path is the same as described above.

On the other hand, the present invention does not exclude the case where a portion of the inner surface of the air flow path is joined to each other so as to additionally control the flow of air to at least one selected from the front or the rear of the air flow path cross-sectional reduction means. FIG. 10 illustrates an example in which the junction 190 is formed at each of the front and the rear of the air flow guide plate 120. The junction part 190 is formed by bonding the inner surfaces of the air flow paths 40 to each other, and may be formed by selecting any one of various methods widely known in the related art, such as compression.

In addition, the present invention proposes a case where a plurality of protrusions are formed on at least one selected from the front part or the rear part of the air flow guide plate. 11 and 12 each show an example of such an embodiment, in which a plurality of protrusions 110 are formed at the rear portion of the air flow guide plate 120. When the air flows into the air flow guide plate 120, the protrusion 110 prevents the air flow guide plate 120 from being in close contact with the inner surface of the air flow path 40 so that air flows smoothly inside the air flow path. It will help you do it. Although not disclosed, it is to be understood that junctions may additionally be formed in this embodiment.

In addition, the present invention proposes a shock absorber having the configuration as shown in FIG. 2 as another embodiment of the shoe shock absorber, wherein the schematic planar configuration and cross-sectional configuration of the air flow path cross-sectional reduction means constituting the shock absorber are shown in FIGS. 13 and 14, respectively. Is disclosed. This embodiment can control the sudden flow of air by constantly pressing the outer surface of the air passage with the clamp 160. That is, by mounting the clamp 160 to maintain the constant internal spacing on the outer surface of the air flow path 40, the air flow path at the point where the clamp 160 is mounted is more than the other point of the air flow path by the structure of the clamp itself The area is kept small to control sudden air inflow, and even under constant external pressure, the structural support of the clamp prevents the rapid flow of air.

As another example of the air flow path cross-sectional reduction means, the present invention does not exclude a configuration in which the joint is additionally provided at either the front or the rear of the clamp, or at both the front and the rear of the clamp, in addition to the clamp. The above description can be applied as it is to the added junction configuration, and detailed description thereof will be omitted. 15 and 16 each show an example of an air flow path cross-sectional reduction means in which the joining

portions

196 and 197 are added to the front and rear of the clamp in addition to the clamp 160 configuration. In addition, in this embodiment, the case where a separate elastic body is added between the clamp and the outer circumferential surface of the clamp or the inner circumferential surface of the portion of the air passage that the clamp wraps is not excluded. According to this configuration, there is an advantage that the air flow can be additionally controlled by the elastic body.

In addition, the present invention does not exclude a case in which the air flow guide plate is installed inside the air flow path, and any one end selected from both end portions of the air flow guide plate is combined with the air flow path inner surface. This embodiment is different from the embodiment disclosed in FIG. 5 in that a coupling part for securing a certain space between the air flow guide plate and the inner surface of the air flow path is formed only at one end of both sides of the air flow guide plate. There are technical features. By this feature, one end of the air flow guide plate is supported by the coupling portion 142 to ensure a space of a predetermined distance between the air flow guide plate and the inner surface of the air flow path to facilitate the inflow of air, The other end side of the air flow guide plate is not provided with a coupling portion does not have a coupling portion for supporting a certain space between the air flow guide plate and the inner surface of the air flow path is not secured space for air flow Accordingly, even when air is introduced by external pressure, air does not flow from the other end without the coupling portion toward one end with the coupling portion, thereby providing the same result as if the one-way valve is installed.

An example of this embodiment is shown in FIG. 17, which shows a case where one end of both sides of the air flow guide plate 122 is coupled to the inner surface of the air flow path by the coupling part 142. Also in the configuration of this embodiment may be additionally provided with an additional junction 192 in the same manner as in the above-described embodiment. In the case of such a configuration, the air flow path cross-sectional reduction means is operated as a one-way valve so that air flows only in the flow direction of air shown in FIG. The present invention is not modified to exclude the case in which the coupling portion 142 is formed in the width direction of the air flow path at any portion selected from the front portion or the rear portion instead of both sides of the air flow guide plate 122. Do not. However, in this case, it is obvious that part of the coupling part should be configured to allow air to flow through only that part.

On the other hand, the present invention does not exclude the case where the coupling portion is formed only at one end of the air flow guide plate and then an induction pipe that can assist the flow of air is added. FIG. 12 illustrates an example in which the coupling part 144 is formed only at one end of the air flow guide plate 124, and the induction pipe 130 is fixedly coupled to the coupling part 144. . The induction pipe 130 is maintained in a fixed state on the inner surface of the air flow path 40, so that the air can flow only through the induction pipe 130, the coupling portion 144 of the c-shape as disclosed It is preferable that the induction pipe 130 is fixedly coupled through the coupling part.

In addition, the present invention does not exclude a case in which a separate clamp is further added to this configuration provided with an induction pipe, but an example thereof is disclosed in FIG. 19. As disclosed, one end of the air flow guide plate 124 is provided with a coupling portion 144 and the guide tube 130, the other end of the air flow guide plate 124, the clamp 162 is an air flow path 40 The outer surface of the shell is wrapped at the same time and a constant pressure is applied. This embodiment is characterized in that the primary control the flow of air by the coupling portion 144 and the guide pipe 130, and the secondary control of the flow of air by the clamp 162. It is apparent that the configuration and operation of the clamp can be applied to the description of the embodiment of FIG. 13 as it is. Of course, the above-described junction part may be additionally provided in the configuration of this embodiment, and the present invention may separate air flow control means between the clamp and the outer surface of the air passage or in the inner surface of the air passage where the clamp wraps. In addition, the case where an elastic body is added is not excluded.

In addition, the present invention in the configuration of the air flow path cross-sectional reduction means, instead of the air flow guide plate configuration to form a first coupling portion and the second coupling portion in the width direction inside the air flow path, the first coupling portion and the second coupling We propose a case where one-way airflow derivative is settled in the space between the parts. 20 is an example of such an embodiment, a first coupling part 126 having an air flow hole 127, a second coupling part 128 formed spaced apart from the first coupling part 126 by a predetermined interval, And the configuration of the one-way air flow derivative 150 is placed in the space between the first coupling portion 126 and the second coupling portion 128.

In this configuration, when air is continuously introduced through the air flow path 40, the air passes through the air flow hole 127 by the first coupling part 126 and passes the one-way air flow derivative 150. Both ends of the one-way air flow inductor 150, which is pressed and not supported by the second coupling part 128, are bent by air pressure, and the air introduced through the air flow hole 127 is directed toward the opposite air flow path. Flow (see FIG. 21). On the other hand, when air flows in the direction of the second coupling part 128, the one-way air flow derivative 150 is supported by the first coupling part 126 in its original shape, thereby preventing the flow of air. . To this end, the one-way air flow derivative 150 is preferably determined within a range between the air flow passage 40 inner width size and the air flow hole 127 size, the material is compressed and restored depending on whether the air is compressed It is preferably made of an elastic body so that it can be. This embodiment may also be provided with additional junctions in the same manner as the above embodiment.

In addition, the present invention is the air flow path cross-sectional reduction means, the air flow hole is formed in each of the pair of engaging surfaces formed in the width direction of the inner surface of the air flow path in a state spaced apart by a predetermined interval, the space between the coupling surface The case where the elastic body is placed is not excluded. An example of such a configuration is shown in Fig. 22, where 129 is a mating surface and 152 is an elastic body. That is, the air flowing into the air passage 40 is controlled by the coupling surface 129 excluding the air hole (not shown), and the air passing through the air hole is additionally flowed by the elastic body 152. Under control, proper buffer adjustment is possible. It is obvious that the junction can be formed additionally in this embodiment.

In addition, the present invention proposes a case of using a comb clip 170 provided with a plurality of comb 174, as shown in FIG. The comb teeth 174 are wrapped in the outer surface of the air flow path 40 in a width direction, it is preferably made of at least two so as to be spaced apart at a predetermined interval so as to wrap the other outer surface of the air flow path with a certain pressure. .
