Description

Shoes {Shoes}

The present invention relates to a shoe worn on the foot, and more particularly to a shoe in which the cushioning function is further improved and the deformation of the window member is suppressed as much as possible.

As is well known, there are various kinds of shoes worn to protect the foot from the outside, but it is usually divided into a window member that supports the weight while protecting the sole and an outer shell protecting the foot.

These shoes, in recent years, rather than a function to protect the foot from the outside, it is important that the function to properly absorb the impact of the weight so that the wearer feels comfortable, and that the appropriate athletic performance according to the athletic characteristics is appropriately improved. It is becoming.

In particular, efforts to improve the cushioning function of the shoe has been studied in various fields for a long time, and as a result of this, the method of using the window member as a foamed resin material with excellent cushioning function and the air cushion tube as the window member It has been suggested to use it and has already been widely used.

However, according to the prior art, when the load is repeatedly applied to the window member, the restoring force of the window member or the air cushion tube of the foamed resin material is greatly decreased (deformation due to the repeated load), and the shock absorbing function is greatly reduced. do.

Therefore, when the shoe is used for a long time, the shock transmitted to the foot is increased due to the deterioration of the cushioning function, so that the wearer easily feels tired, and the foot joint of the wearer is seriously injured, thereby causing the product of the shoe. The problem is that the life is shortened.

In addition, there is a limit to improve the cushioning function by changing the material of the window member, there is a problem that the improvement of the buffering function by the air cushion tube is also limited in a certain limit.

Accordingly, the present invention has been invented to solve the above problems, the object of the present invention is to provide a shoe that is further improved cushioning function, the deformation of the window member is suppressed as much as possible.

The present invention for achieving the above object is made of a window member to support the weight while protecting the sole, and the outer shell to protect the instep, the window member, the sole in contact with the ground, the insole in contact with the sole, It is composed of a midsole that is disposed between the sole and the insole to cushion the impact of the load, at least a pair of permanent magnets are built in a layer on the upper surface and the lower surface of the middle window, the opposite permanent magnets are mutually repelled In the shoe forming the structure, the magnetic shielding means is provided in the lower portion of the permanent magnet disposed toward the sole.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a side view showing a first embodiment of the shoe according to the present invention, Figure 2 is a cross-sectional view taken along the line AA of Figure 1, according to the shoe 1 according to the present invention, while supporting the soles to support the weight Consists of the window member 10 and the outer shell 20 to protect the instep, the permanent magnet (31, 32) is formed in the window member 10 to face each other, the opposite permanent magnets (31, 32) ) Are mutually repulsive. In the first embodiment, the window member 10 is disposed between the sole 11 in contact with the ground 100, the insole 13 in contact with the sole, and the sole 11 and the insole 13 in the load. Consists of the middle window 12 to cushion the impact by, the permanent magnet (31, 32) forms a structure built in the middle window (12).

1 and 2, when a load is applied to the window member 10, the intermediate window 12 is compressively deformed and the shock caused by the load is primarily buffered, and at the same time, the permanent magnet 31 Since the impact due to the load is secondarily buffered by the repulsive force of (32), the cushioning function of the shoe is greatly improved. In addition, since the repulsive force of the permanent magnets 31 and 32 is maintained almost permanently, when the load applied to the window member 10 is removed, the repulsive force of the permanent magnets 31 and 32 is reduced to the intermediate window 12 in the compression-deformed state. It returns to a circular state quickly by this, and the deformation | transformation of the intermediate | middle window 12 by a repetitive load is suppressed. Therefore, the fall of the buffer function by deformation | transformation of the midsole 12, ie, the fall of the restoring force of the midsole 12, is suppressed as much as possible, and the product life of the shoe 1 is extended. This first embodiment is suitable for shoes worn by ordinary adults.

Figure 3 is a view showing a second embodiment of the shoe according to the present invention, according to the second embodiment, the deformation guide hole in the middle portion between the permanent magnets (31, 32) facing the layer forming the layer (12a) is formed.

In this way, when the deformation guide hole 12a is formed in the middle window portion between the permanent magnets 31 and 32, the middle window portion on which the permanent magnets 31 and 32 are installed is deformed to be very flexible, so that the cushioning function is more flexible. There is an advantage to be performed. This second embodiment is suitable as shoes worn by children or adolescents who weigh less.

Figures 4a and 4b is a view showing a third embodiment of the shoe according to the present invention, according to the third embodiment, according to the middle window portion between the permanent magnets (31, 32) facing the layer Air cushion tube 14 is characterized in that the interior, the air space of the air cushion tube 14, 14a is filled with a predetermined pressure. Here, reference numeral "12b" is an opening hole that allows the air cushion tube 14 to be flexible and properly deformed.

As such, when a load is applied to the window member 10 in the state where the air cushion tube 14 is installed in the middle window portion between the permanent magnets 31 and 32, the middle window 12 is compressively deformed and impacted by the load. This is primarily buffered, and at the same time the shock caused by the load is secondarily buffered by the repulsive force of the permanent magnets (31,32), and the air cushion tube (14) is deformed, the internal pressure of its sealed space (14a) Since the shock caused by the load is buffered in the third order, a much improved shock absorbing function can be obtained. These third embodiments are suitable as shoes worn by athletes.

On the other hand, as shown in Figure 3, if the magnetic shield means 40 in the lower portion of the permanent magnet 32 disposed toward the sole 11, by the magnetic force of the permanent magnet 32, even if the metal foreign matters The problem of sticking to the sole 11 can be solved.

According to the present invention as described above, since the deformation of the window member due to the load is suppressed by the repulsive force of the permanent magnet built into the window member, the buffering function is prevented from being lowered due to the deterioration of the restoring force due to the deformation of the window member. In addition, the product life of the shoe is extended, and the cushioning function of the shoe is further improved by the repulsive force of the permanent magnet.

The present invention is not limited to the embodiment as described above, and of course, various modifications can be made without departing from the scope of the following claims.
