The present invention relates to a shock absorbing structure using the repulsive force of a magnet and a shoe equipped with the structure.

Conventionally, as a device for absorbing and cushioning shock and vibration in general, there are various kinds of devices using elasticity of a spring or air compressibility such as an air mat, and such devices have an effect of absorbing impact force and vibration force.

In order to achieve this effect, Korean Patent Application No. 2000-0005385 (Publication No. 201-077535) proposes a vibration damping device using magnetic force. The shock absorbing vibration absorber includes a compressible case and two magnets installed inside the case and rejected with each other by the repulsive force caused by the same poles facing each other, thereby forming a space that can be compressed therebetween. In this way, it is configured to obtain a buffered vibration absorption effect in this configuration.

The shock absorbing vibration absorber is a pair of two permanent magnets installed so that the same poles facing each other, a plurality of pairs of permanent magnets are arranged at a predetermined interval from each other and to cushion the shock or vibration by the repulsive force between the permanent magnets of each pair In practice, the repulsive force between the mutually opposing permanent magnets is so weak that when the external force of a large load is applied, these permanent magnets are almost in close contact with each other. That is, when the device is applied to a shoe, a person with a weight of about 40 to 50 kg walks wearing the shoe, so that the permanent magnets facing each other closely adhere to each other by the weight of the weight. There is little buffering effect. In addition, even if a plurality of pairs of mutually opposing permanent magnets spaced apart from each other appeared that the effect is almost no.

Therefore, in order to improve the repulsion between the mutually opposing permanent magnets, a permanent magnet having a large magnetic force should be employed. In this case, an increase in the volume or weight of the permanent magnet is inevitable. In other words, if the design is applied to the shoe so that the permanent magnet repulsion can withstand close to each other by the weight of the weight but is not in close contact, the shoe must be too heavy by the weight of the permanent magnet and the permanent magnet occupies the sole of the shoe. As the volume becomes too large, it becomes difficult to design comfortable shoes.

On the other hand, shoes using the repulsive force of the magnet is disclosed in Korean Patent Application No. 2002-0016414 (Publication No. 2003-0077344). In this shoe, a ring-shaped magnet with half pole N pole and the other half pole S pole is installed on the sole so that different poles face each other. In this case, as in the case of Korean Patent Application No. 2000-0005385, the repulsion between magnets It was confirmed that there was a problem due to this weakness.

In addition, Korean Utility Model Registration No.0251082 (Double Application Patent Registration No.0434684) has a deformation of the midsole due to the weight of the body due to the repulsive force of two permanent magnets which are installed on the upper and lower surfaces of the midsole of the shoe to face each other. Shoes that are configured to suppress and improve cushioning function are disclosed. In this case, as in the case of Korean Patent Application No. 2000-0005385, it was confirmed that there is a problem due to the weak repulsion between the magnets.

Therefore, in the related art, a technique for absorbing and cushioning external shocks or vibrations by repulsive force between magnets has been proposed, but when applied to an actual product, the effect is almost ineffective. .

Accordingly, the present invention has been made in view of the above-described conventional situation, and magnets facing each other are close to each other even with relatively large loads without significantly increasing the weight and volume of the magnet while using the repulsive force of the magnet. It is an object of the present invention to provide a shock absorbing structure using a repulsive force of a magnet capable of completely absorbing and cushioning external shocks or vibrations, thereby preventing the contact with each other.

In order to achieve the above object, the shock-absorbing structure using the repulsive force of the magnet according to the present invention includes at least two rod-shaped magnets having different polarities in the height direction, which are in close contact with each other in the longitudinal direction, and adjacent magnets have different polarities. A first side magnetic assembly arranged to have; At least two rod-shaped magnets, which are spaced apart from the first magnet assembly by a predetermined distance, have different polarities in the height direction, are in close contact with each other in the longitudinal direction, and adjacent magnets are arranged to have different polarities and face each other. And a second magnet assembly in which magnets are arranged to have the same polarity as that of the magnet of the first magnet assembly.

In addition, in order to achieve the above object, the shoe according to the present invention, at least two rod-shaped magnets having different polarities in the height direction is in close contact with each other in the longitudinal direction and the adjacent magnets are arranged so as to have different polarities A side magnetic assembly; At least two rod-shaped magnets having different polarities in the height direction are arranged to be in close contact with each other in the longitudinal direction, and adjacent magnets are arranged to have different polarities, and have the same polarity as that of the magnets of the first magnet assembly facing each other. The second magnet assembly in which the magnets are arranged so as to have a space between the second side magnet assemblies is arranged to be spaced apart from each other with an air layer at a predetermined interval inside the window member having a stretch force.

Hereinafter, a shock absorbing structure using a repulsive force of a magnet according to a preferred embodiment of the present invention with reference to the accompanying drawings and a shoe equipped with the structure will be described in detail.

1 is a view for explaining the concept of the shock absorbing structure using the repulsive force of the magnet according to the present invention.

As shown in the figure, the shock absorbing structure using the repulsive force of the magnet according to the present invention, the first magnet coupling 10 and the second magnet coupling 20 is arranged spaced apart from each other via air via a predetermined interval It is. As used herein, the expressions "first side" and "second side" are confused because the expression may vary depending on how the shock absorber according to the present invention is arranged, and in which direction the shock absorber is viewed. It is named to eliminate the misunderstanding. That is, in the drawing, the "first side" is the upper side and the "second side" is the lower side, but when the drawing is turned 90 degrees clockwise, the "first side" becomes the right side and the "second side" becomes the left side. Because.

The first magnet assembly 10 has a structure in which three magnets 10A to 10C are wrapped in half with the first magnet coupling housing 12, and the second magnet assembly 20 has three magnets. It is structured to wrap 20A-20C by the 2nd magnet coupling housing 22 in half. Here, the first and second magnet coupling housings 12 and 22 are made of iron plates and have a shape in which portions facing each other are opened. In other words, the magnets 10A to 10C on the first side and the magnets 20A to 20C on the second side face each other. Here, in the present example, a structure in which three magnets are coupled in one magnet coupling housing is exemplarily illustrated, and of course, two or four or more may be coupled in one magnet coupling housing. In addition, in the accompanying drawings, the front and / or rear part of the magnet is not enclosed by the magnet coupling housing for the purpose of simplicity and understanding of the drawings, but the front part and / or the rear part of the magnet is also half by the magnet coupling housing. It is desirable to be wrapped around.

Here, the three first side magnets 10A to 10C having different polarities in the height direction are closely contacted with each other in the longitudinal direction, and adjacent magnets are arranged to have different polarities, and also have different polarities in the height direction. The three first side magnets 20A to 20C are also in close contact with each other in the longitudinal direction, and adjacent magnets are arranged to have different polarities.

In addition, the three second magnets 20A to 20C have magnets arranged to have the same polarity as the first side magnets 10A to 10C facing each other. That is, the opposing surfaces of the first side magnet 10A and the second side magnet 20A facing each other are the same N pole, and the first side magnet 10B and the second side magnet 20B facing each other are the same. The opposing surfaces are the same S poles, and the opposing surfaces of the first side magnet 10C and the second side magnet 20C facing each other are the same N pole.

Therefore, between the first side magnet 10A and the second side magnet 20A facing each other, between the first side magnet 10B and the second side magnet 20B, and between the first side magnet 10C and the first side magnet 10A. Between the two magnets 20C, repulsive force, which is a repulsive force, acts respectively.

Concatenate two permanent magnets with a magnetic flux density of 3500 G (Gaussian) in one magnet coupling housing and measure their magnetic flux density, and use 3 permanent magnets with a magnetic flux density of 3500 G (Gaussian) in one magnet coupling housing. Dogs were spliced and their magnetic flux density was measured. Approximately 4000 G was measured when two permanent magnets were connected, and 4500 G was measured when three permanent magnets were connected. As such, when a plurality of bar magnets are jointly coupled, the magnetic flux density increases.

In addition, the magnet opposing housing 12, 20 is opened to face the magnet 10A to 10C (20A to 20C) so that the surface facing the open, the magnetic flux is prevented from escaping to the side of the housing wrapped The imbalance of the flux flow causes the magnetic force to increase toward the unenclosed housing.

Therefore, as the plurality of rod-shaped permanent magnets are connected to and coupled to the first and second magnetic coupling bodies 10 and 20, the first and second magnetic coupling bodies 10 and 20 are further connected between the first and second magnetic coupling bodies 10 and 20. Stronger repulsive forces will work.

2A and 2B are schematic diagrams of a shock absorbing structure using repulsive force of a magnet according to a preferred embodiment of the present invention.

As shown in the figure, the shock absorbing structure using the repulsive force of the magnet according to the present invention, the first buffer member 15 surrounding the first magnet assembly, and the second buffer member surrounding the second magnet assembly And a casing member 30 surrounding the first buffer member 15 and the second buffer member 25 spaced apart from each other by a space of a predetermined interval. In the figure, the front of the casing member is shown open only for convenience of explanation and understanding, but it is preferable that substantially all six surfaces are sealed.

In addition, the casing member 30 is preferably fixed to the first buffer member 15 and the second buffer member 25 by an adhesive, even if not bonded, the first side magnetic coupling body and the second side magnet As the repulsive force between the combination is acting, if an external force is not applied, it maintains a constant distance from each other.

In addition, the casing member 30 should be made of a flexible and tough material as a whole, or at least a portion corresponding to the gap space formed by the separation of the first buffer member and the second buffer member should be made of a flexible material. do.

When an external force is applied to the shock absorbing structure of the present invention configured as described above in the A direction and / or the B direction, the repulsive force between the first magnet coupling body and the second magnet coupling cancels in proportion to the magnitude of the external force. Accordingly, the distance between the first side magnet coupling body and the second side magnet coupling body, that is, the distance between the first buffer member 15 and the second buffer member 25 is narrowed.

The inventors of the present invention concatenate three permanent magnets each having a length, width, height of 5 cm, 1.5 cm, and 1 cm, and a magnetic flux density of 3500 G by connecting the first magnet coupling body and the second magnet coupling body with a magnetic flux of 4500 G. The density was generated and the first and second magnet assemblies were applied to the shoe as shown in Figs. 3A and 3B. And a 70-kg-weight person walked in the shoes and found that there was still a space gap when walking. This is because the repulsive forces between the magnet assemblies could not be canceled by the pressed load.

Accordingly, the shock absorbing structure of the present invention is designed to appropriately design the length, width, height, magnetic flux density of the magnet, and the number of magnets constituting one magnet assembly according to the application thereof, thereby providing an external force suitable for the application. It is expected to be able to perform a buffering action by absorbing shock.

Between the sole and the sole 44 is made of an intermediate window 42 made of a elastic material such as urethane. The shock absorbing structure according to the invention is mounted on the midsole 42.

That is, the three rod-shaped magnets having different polarities in the height direction are in close contact with each other in the longitudinal direction, and the adjacent magnets are arranged to have different polarities, and the first magnet assembly 10 arranged in the height direction has different polarities. The magnets are arranged such that the three bar-shaped magnets are in close contact with each other in the longitudinal direction and magnets adjacent to each other are arranged to have different polarities and have the same polarity as the magnets of the first side magnet assembly 10 facing each other. The two-side magnet assembly 20 is spaced apart from each other in the middle window 42 made of elastic elastic elastic resin material with the air layers of the air cushion tubes 48 spaced from each other.

Here, the first side and the second side magnetic assembly 10, 20 is substantially the same as the configuration described with reference to FIG. The air cushion tube 48 is preferably formed with a plurality of through holes 49 for the air outflow and inflow of air.

In addition, the first and second magnet assemblies 10 and 20 are preferably molded at the time of manufacturing the intermediate window 42, and the air cushion tube 48 and the through-hole 49 are also formed. It is desirable to.

According to the shoe equipped with a shock absorbing structure using the repulsive force of the magnet configured as described above, there is still a space gap in the stepping foot when walking in the shoe, so that the impact on the soles, ankles and knees due to the weight It can absorb and almost completely absorb vibrations.

In FIGS. 3 and 4, the length direction of the shoe and the length direction of the magnet coincide with each other, but the magnet may be disposed such that the length direction of the shoe and the length direction of the magnet are perpendicular to each other.

In addition, this invention is not limited only to the specific Example mentioned above, It can implement | transform in various ways, and can implement it in the range which does not deviate from the summary of this invention.

As described above, according to the present invention, the magnetic flux is increased by a magnetic coupling body in which a plurality of magnets are connected in series, and the magnetic coupling bodies are disposed to face each other in the same polarity direction, thereby greatly increasing the weight and volume of the magnet while using the repulsive force of the magnet. It is possible to completely absorb and cushion external shocks or vibrations by preventing the magnets facing each other from close to each other even under relatively large loads, but not contacting each other by repulsion between them even without a large load.
