Description

Shoe Window {SOLE OF SHOE}

The present invention relates to a shoe window which is inserted into and used inside a shoe.

Normally, when the person touches the ground when walking, the person touches the outside of the hind axle, and then the inside of the hind axle touches as the ankle turns inward, and then moves the center of gravity toward the front of the foot, causing the foot to rotate outward again. Pronation movement is performed to minimize the impact on the body.

However, in some people, when the center of gravity moves from the outside of the heel to the inside, as shown in Fig. 13 (a), the ankle is excessively turned inward or there is little or insufficient movement inward. The concave part of the can't function properly and can be absorbed by the foot.

Here, the recesses of the soles of the feet are referred to as foot arches or arches of the feet, which may cause injury by not absorbing shocks when walking, and may cause walking for a long time, as well as vaginal valgus and callus. , Various symptoms such as flat feet, joint pain, knee pain, shin stress, fracture and ankle pain can be accompanied and worsened.

As mentioned above, it is argued that unfavorable foot function is a decisive factor in all walking-related diseases in the medical and biomechanical fields. This is based on the fact that they all come from people who have used shoes.

Therefore, there have been many technologies to compensate for excessive adduction or abduction of the foot, which is a characteristic of non-ideal gait caused by the use of shoes. It was only to prevent the phenomenon from happening temporarily, which made it difficult to develop into a normal walking system.

Of these technologies, U.S. Patent No. 4,232,457, Mosher introduced an assistive device made of a hard or slightly elastic material, focusing primarily on supporting the inner arch of the foot. In addition, in US Pat. No. 5,085,585, Kendal uses a modified horseshoe-shaped device for supporting the inner arch to support the user's foot or help walking.

In the end, they weaken the musculoskeletal structure surrounding the foot, and due to the structure of the foot that is continuously weakening, there is a problem that requires the use of a stronger and more dependent instrument.

As a more ideal solution, U.S. Pat. .

However, the use of the instrument invented by Burke and Gardiner does not support the inner part of the foot in the direction of supporting or directing the foot for biomechanical walking, which is ideal for early use and recovery. I found that there are significant limitations in terms of direction.

In other words, these instruments stimulate the foot to some extent but take a long time to act as corrections, so there is a need for a technique that can reduce the dependence of the assistive device while providing an immediate correction role and a gradual healing effect. will be.

On the other hand, the technology by Burke and Gardiner is remarkable in that the main apex located at the intersection of the cubic bone, the scapula and the outer tongue, and the inside of the user's shoe due to the pressure applied to the sole during walking, jogging and driving We see the result of the instrument moving from outside to inside.

Indeed, the apex of the foot is much wider and more inward than Burke and Gardiner's introduction, and this narrow peak causes intense pressure on the foot, causing severe discomfort, which can cause damage to the instrument.

The reason for this is that when the user walks the foot, the natural phenomenon of turning the foot is accompanied by excessive strain on the muscles that support the movement of the foot to match the centered vertex, especially as shown in Figs. 1 and 2, Gardiner The apex (a1) located in the position introduced by the result increases the degree of adduction during walking, adding fatigue to the musculoskeletal system of the user, and increasing the possibility of discomfort and injury.

The present invention is to solve the above-mentioned problems, to overcome the excessive pronation of the foot can be strengthened the musculoskeletal system including the bones and muscles and related tissues of the foot necessary for ideal walking, while at the same time resulting from the structure of the weakened foot The purpose is to provide a shoe window that can help strengthen the muscles of the foot to overcome the civil war.

The preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, in which the technical parts already known will be omitted or compressed for simplicity of explanation.

Window 100 of an embodiment of the present invention, as shown in Figures 2 to 16, includes a structure 110 and the bottom body 120 to abut the arch portion of the foot in contact with the arch (Arch) of the foot. It is configured by. Here, the arch refers to an open portion that does not touch a flat plane as a recessed portion of the foot.

At this time, the structure 110 may be made of a material having flexibility and compressibility to give comfort to the sole surface. For example, it is possible to use polyurethane or derivatives thereof, ethyl vinyl acetate or derivatives thereof, viscoelastic polymers, natural sponge rubbers and derivatives thereof, and other embodiments of the present invention. Other materials applicable to the examples may be used.

Meanwhile, as shown in FIGS. 3 and 4, the structure 110 has a protruding shape to contact the arch. In the center of the structure 110, the front portion of the medial tubercle of the talus, the main bone, and the first lingual bone And a circumference located on the inner side of the cuboid is formed in a “T” shape, as shown in FIGS. 12A and 12B, close to a triangular shape, or as shown in FIG. 12C. Various configurations are possible, such as a surface, such a contact surface 115 is configured to include a support 111, a magnetic pole 113, and the like.

As shown in Figure 5, the support 111 is configured to support the open space of the arch in the direction of the axis (e) that hangs from the first metatarsal bone, the longest side of the triangle shape of the first metatarsal bone It is an inner part of the foot parallel to the axis (e), and has a surface extending to the medial portion of the columnar bone, it is configured to be located in a portion that does not exceed the outer surface of the second metatarsal bone.

As shown in FIGS. 4 to 6, the magnetic pole part 113 stimulates a position corresponding to the first lingual bone, a part of the second lingual bone, the main bone and the talus of the foot. Among these, the central position to be stimulated is the medial part of the vertebral bone as shown in Figs. 4 and 5, which is a part (a2) corresponding to the part not exceeding the lateral surface of the second metatarsal bone, This is the most desirable position to overcome.

The stimulating part is a face that comes into contact with the abdominal muscles of the flexor digit flexor muscle (Flexor Digitorum Brevis) and the flexor hallicus longus (flexor hallicus longus). To help.

At this time, the stimulation unit 113 is configured to stimulate the foot by making a surface having a certain area rather than stimulating only a narrow peak of a specific site, thereby strengthening the muscles of the foot that can overcome excessive pronation. Here, it is preferable to apply the embodiment of the present invention so that the height of the contact surface 115 is not less than 2.5% of the full length of the foot, and not greater than 7.5%.

On the other hand, the structure 110 is composed of a contact surface 115 having a constant area at the top contacting the arch of the foot, which is configured to form a surface 115 originating from the support 111 and the pole portion 113.

Here, the structure 110 is inclined outward from the contact surface 115 at the top, and the inclined surface abuts the arch portion of the foot. Here, the boundary b at which the inclination ends is formed to include the inner side corresponding to the open outer side of the arch and the 2/3 point of the second metatarsal bone, the outermost side of the cubic bone and the medial nodule of the calcaneus.

Therefore, the corresponding portion of the support portion 111 of the contact surface 115 of the structure 110 to support the arch portion of the foot to adjust the excessive pronation phenomenon, the stimulation portion 113 by weakening the muscles by continuously stimulating the muscles It is configured to help strengthen this.

In addition, the bottom body 120 extends from the structure 110 and abuts the bottom of the foot, and is used as the window 100 of the shoe having one configuration coupled with the structure 110, or the structure 110 and the bottom. Sieve 120 may be used in a variety of configurations, such as used as the window 100 of the shoe can be separated from each other.

Meanwhile, as shown in FIG. 11, the window 100 of the shoe according to the embodiment of the present invention has a portion o1 and a boundary b corresponding to the first metatarsal bone adjacent to the outside of the boundary b in the structure 110. The portion (o5) corresponding to the fifth metatarsal adjacent to the outside of the body may have a thickness less than or equal to a certain thickness or less than other portions that meet the boundary surface (b) to adapt to the movement of the foot in a flexible state when walking. It is possible to configure so that.

Further, the structure 110 extends downward from the contact surface 115, and as shown in Fig. 5, at positions corresponding to the axis d extending parallel to the second metatarsal bone, Figs. As can be seen in b), ridges are formed.

These ridges are configured to permit movement of the foot within a range that does not deviate by more than 12 degrees in the inward and outward direction of the foot with respect to the axis d extending parallel to the second metatarsal bone. These variables allow for the acceptance of anatomical changes due to genetic trends or external influences that can lead to malformations of the foot, such as big toe valgus or hallux valgus.

In addition, the structure 110 has an extension line p extending downwardly from the contact surface 115 which abuts the arch and extends asymmetrically in the portion of the talus adjacent to the calcaneus of the foot, the back of the calcaneus side corresponding to the extension line p. In the front, it is preferable to be configured to increase the density from the outside of the foot to the inside to prevent excessive pronation of the foot.

In other words, the structure 110 allows a portion to gradually increase in density from the outside of the foot to the inside of the foot at the same time from the back of the foot, thereby reducing the phenomenon of the outside of the calcaneus side, which is characteristic of excessive pronation. By providing a surface inclined forward from the outside of the calcaneus and from the rear of the calcaneus, as shown in FIG. 13 (b), the foot is corrected to reduce excessive adduction.

Meanwhile, in the embodiment of the present invention, the first and second inserts serving as the support 111 and the magnetic pole 113 may be inserted into the structure 110 and used as shown in FIG. 14. The first and second inserts having the compressive force may be inserted into the triangular-shaped contact surface 115 accompanying the same.

The first and second inserts are replaceable, and the first insert serves to support the muscles, which are the role of the stimulator 113, in order to control excessive pronation by the role of the support 111. As shown in FIG. 9 for stimulation, each may be configured in a separate and independent form.

At this time, the first and second inserts are used to change the height and compression characteristics according to the role of the user by using the spring, liquid, hydraulic mechanism and compressible material to adjust the height and compression characteristics according to the role of the user It is possible.

That is, the first insert adjusts its height and compression characteristics to adjust the desired degree of adduction phenomenon, and the second insert may adjust its height and compression characteristics to adjust muscle active pressure. In addition, it is configured to enable the user to use the difference between the first and second inserts according to the type of shoes, flexibility, the degree of muscle structure change and the degree of pronation required.

On the other hand, the second insert is mounted on the site that presses upward pressure on the flexor digit flexor (Flexor Digitorum Brevis) and flexor hallicus Longus (near flexion) required for muscle activity.

The foot's response to this pressure is to contract the muscles to strengthen the muscles of the foot. Therefore, the first and second inserts are replaced with each other to adjust the degree. As shown in FIG. 10, the first and second inserts have different height, density, and compression characteristics and are connected to each other. It is also possible to have

Alternatively, as shown in Fig. 9, it is also possible to use a configuration such as a protrusion f that can apply pressure to the foot so that the surface of the second insert can give additional stimulation to the muscles of the foot.

As another method for implementing the shoe window 100 of the embodiment of the present invention, a molding method or an injection method may be used to control the compression characteristics of the first and second inserts, and the thermoplastic rubber and its Derivatives, silicones and derivatives thereof, and thermoplastic urethanes and derivatives thereof may be prepared by pouring or injecting viscoelastic liquids. In addition, by inserting or applying other materials having various compression characteristics, it is possible to have a control function using a mechanism such as a spring, a compressed gas, and an air bag.

On the other hand, as shown in Figure 14, as shown in Figure 14, by inserting the first and second inserts (h1, h2) for the first and second inserts in the structure 110, the first insert for adjusting the pronation phenomenon is inserted And a second insertion hole h2 for inserting a second insert for stimulating a muscle in contact with the contact surface 115 of the structure 110.

In this case, each of the insertion holes h1 and h2 fits the sizes of the insertion holes h1 and h2 to accommodate the first and second inserts according to a predetermined ratio, so that the first and second inserts are inserted into the insertion holes h1 and h2 by frictional force. It is preferable to be configured so as not to fall out from the), and it is preferable to configure an adhesive, a hook, a hook-type binding mechanism or a clasp relationship between the insertion holes h1 and h2 and the first and second inserts in the insertion holes h1 and h2. The first and second inserts can be inserted and fixed.

Alternatively, as shown in FIG. 15, there is a lower layer in a product consisting of an insole and a midsole of a shoe or an outsole, a midsole and an insole of a shoe, and a structure 110 having first and second inserts in the lower layer. The structure 110 is mounted on the upper surface of the lower layer by being mounted, and can be attached by attaching using adhesive or by using a ring or the like, and it is possible to use a material such as Velcro.
