Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to shoe inserts for correction, and more specifically to shoe inserts for correction which not only corrects unevenly deformed joints of a human body evenly by wearing shoes with shoe inserts inside but also provides enough massage effects.
2. Description of the Related Arts
Basically, shoe inserts were used to absorb or disperse shock as much as possible by putting shoe inserts inside shoes so that shock mainly occurring while walking is not given directly to feet and not transmitted to a human body, or to correct shoes when shoes are loose because the size of shoes are bigger than feet.
These shoe inserts may have effects of cushioning and size correction, however, these shoe inserts also had problems of not preventing pain of feet and knees and also, in worse cases, diseases such as arthritis, or cervical and lumbar discs occurring by having bad impact on joints of the knees, the hip, the waist and the neck since a leg becomes twisted when the heel is twisted because the structure of feet supporting most of weight while walking is not normal.
That is, femur and tibia make ideal angle and the up-and-down space between inner side and outer side of the knee joint is balanced in case of having normal legs for an exemplary embodiment, on the other hand, the knee joint and the hip joint become twisted when a heel is twisted due to the side wear of a shoe or bad walking habit, thus generating unstable standing posture or walking posture since legs bend in a ‘O’ shape if up-and-down space of outer side of the knee joint is bigger than that of inner side, and also causing degenerative arthritis since the friction pressure of inner side of the knee increases. On the contrary, if legs bend in a ‘X’ shape when up-and-down space of outer side of the knee joint is smaller than that of inner side, the shock absorption is occurred due to the imbalance of the knee or hip joint in the process of transmitting mobility generated from a foot to the upper body through the knee, and mobility cannot function at its best.
So, shoe inserts for correction were proposed to solve these problems in the past, wherein narrowing the space between the knees which were widened in a ‘O’ shape when using shoe inserts for correction for a long time by forming the rear portion supporting the rear-sole portion flat and forming the middle portion and the front portion supporting the middle-sole portion and the front-sole portion to be inclined upwardly to the outer side so that the outer side edge of the middle-sole portion and the front-sole portion gets lifted from the sole of the foot to the side of the little toe by the inclined surface when wearing the shoes.
These shoe inserts for correction had problem of not correcting when a heel is twisted since only edges of outer side of a middle-sole portion and a front-sole portion were lifted up by the inclined surface, excluding the heel, while keeping the heel in a flat state same as normal shoe inserts.
In addition, these shoe inserts for correction had disadvantage of having limited purpose since the shoe inserts for correction cannot be used in the correction of ‘X’ shaped knee since only edges of outer side of the middle-sole portion and the front-sole portion are lifted up, and also had problems of causing waste of resources and costs since the shoe inserts should have been manufactured not only in various sizes with different heights of the inclined surface in order to fit the foot size of the users but also in whole size of the sole of a foot.

SUMMARY OF THE INVENTION

The present invention is invented by considering these and the purpose of is to provide shoe inserts for correction to effectively correct twisted heel so that not only the pain of feet and knee but also diseases such as arthritis or cervical and lumbar discs can be prevented.
In addition, the other purpose of the present invention is not to waste resources and costs.
Moreover, another purpose of the present invention is to provide shoe inserts for correction which contributes to health maintenance by preventing wearing discomfort and also improving massage effect sharply.

The shoe inserts for correction are provided to not waste resources and costs and to correct legs by choosing and using the shoe inserts whether which side between the outer side or the inner side of the heel is twisted by placing the body having the correction means disposed at the inner side of the lower surface of the rear-sole portion into the shoes when legs are bent in a ‘X’ shape since the up-and-down space of inner side of the knee joint becomes bigger than that of the outer side, whereas, by placing the body having the correction means disposed at the outer side of the lower surface of the rear-sole portion into the shoes when legs are bent in a ‘O’ shape since the heel is twisted and the up-and-down space of inner side of the knee joint becomes smaller than that of the outer side.
In addition, the present invention provides shoe inserts for correction that can choose and use the right ones by comprising a correction means protruding downwardly in an integral form on the lower surface of the rear-sole portion or comprising a separately manufactured correction means coupled to the lower surface of the rear-sole portion and at the same time forming the up-and-down thickness in proportional to the twisted degree of a heel.
Moreover, the present invention provides shoe inserts for correction comprises; a body formed in a size supporting only bottoms of a rear-sole portion and a middle-sole portion of a foot; a correction means disposed at one of an outer side or an inner side of the lower surface of the rear-sole portion of the body in a manner of crossing back and forth; a coupling recess recessed into a portion corresponding to an arcuate portion of the foot; a massage member formed of one of soft synthetic resin, rubber or rubber magnet to gain sufficient massage effect when wearing the shoes by forming in different heights according to the depth of the arcuate portion and inserting and coupling to the coupling recess after selecting the right one according to the depth of the arcuate portion; and a slide-preventing means for preventing the body from being slid forward.
Furthermore, the present invention provides shoe inserts for correction comprises a slide-preventing means with a friction member disposed at the front end portion of the lower surface of the body or with a size supporting the entire sole, and which is formed in a shape of an insole comprising a supporting jaw formed at a boundary, formed by making the rear portion thinner than the front portion, between a front-sole portion and a rear portion to support a front end portion of the body and thus prevent the body from being slid forward while using the slide-preventing means.

Effects of the Invention

The shoe inserts for correction according to the present invention is characterized to correct twisted heel more effectively by selecting and using shoe inserts comprising correction means with right location and thickness according to which side of heel is twisted and the twisted degree.
In addition, resources and costs are not wasted since shoe inserts for correction are not manufactured in various sizes that is proportional to size of feet or twisted degree of heel by manufacturing separate correction means and coupling to lower surface of a real-sole portion.
Moreover, the shoe inserts for correction may have advantage of massage effect and good wearing comfort since a body is not being slid forward.

DETAILED DESCRIPTION OF THE INVENTION

As follows, shoe inserts for correction according to the present invention is described in detail in accordance with attached drawings.
FIG. 1 is a perspective view of a shoe insert for correction according to the first exemplary embodiment of the present invention. FIG. 2 is a perspective view illustrating a lower surface of shoe inserts for correction of FIG. 1. FIG. 3 is a cross-sectional view illustrating the use state of a shoe insert for correction of FIG. 1 from the side.
The shoe inserts for correction according to the first embodiment of the present invention of FIG. 1 to FIG. 3 is characterized by comprising a body 10 and a correction means 20 formed in the lower surface of the body.
The body is formed in a size supporting only bottoms of a rear-sole portion and a middle-sole portion of a foot, excluding a front-sole portion, and an upper surface 11 is formed in a manner of supporting bottom by adhering to the bottoms of the rear-sole portion and the middle-sole portion.
In addition, a massage member 12 is formed at a portion of the upper surface 11 corresponding to an arcuate portion of a foot to stimulate the sole of a foot so that blood circulates smoothly. Around a massage member, a great number of air holes 13 are formed to be penetrated up and down and it is ventilated between the upper surface and the sole of a foot so that it prevents from sweating or generating smell.
A correction means 20 is disposed at one of an outer side or an inner side of the rear-sole portion, supporting a heel, on a lower surface 14 of a body 10 in a manner of crossing back and forth.
That is, a correction means 20 is disposed at outer side of the rear-sole portion of the lower surface 14 in case where legs are bend in a ‘O’ shape since outer side of a heel is twisted downward and the up-and-down space of inner side of the knee joint becomes smaller than that of outer side of the knee joint. On the other hand, the correction means is disposed at inner side of the rear-sole portion of the lower surface in case where legs are bend in a ‘X’ shape since inner side of a heel is twisted downward and the up-and-down space of inner side of the knee joints becomes bigger than that of the outer side of the knee joint.
Accordingly, when placing a body 10 in which a correction means 20 is disposed at the outer side of the rear-sole portion into a shoe, the outer side of a heel is lifted when wearing shoes since outer side of the rear-sole portion becomes higher than that of inner side in proportional to the up-and-down thickness of the correction means in case of ‘O’ shaped legs.
In this case, the up-and-down space of the outer side gets smaller slowly since pressure generated according to the degree how much outer side of a heel is lifted is applied to the outer side of the knee joint, whereas, the up-and-down space of the inner side of the knee joint where pressure is not affected gets bigger, and thus the up-and-down spaces of outer and inner side of the knee joint are corrected to be even and ‘O’ shaped legs become balanced legs.
On the other hand, when placing a body 10 in which a correction means 20 is disposed at the inner side of the rear-sole portion into a shoe, the inner side of a heel is lifted when wearing shoes since inner side of the rear-sole portion becomes higher than that of outer side in proportional to the up-and-down thickness of the correction means in case of ‘X’ shaped legs.
In this case, the up-and-down space of the inner side gets smaller slowly since pressure generated according to the degree how much inner side of a heel is lifted is applied to the inner side of the knee joint, whereas, the up-and-down space of the outer side of the knee joint where pressure is not affected gets bigger, and thus the up-and-down spaces of outer and inner side of the knee joint are corrected to be even and ‘X’ shaped legs become balanced legs.
Also, it is reasonable to provide a correction means 20 in various up-and-down thicknesses so that users may choose and use the ones having right thickness according to twisted degree of a heel.
FIG. 4 is a perspective view of a lower surface of a shoe insert for correction according the second exemplary embodiment. FIG. 5 is a perspective view illustrating a shoe insert by separating a shoe insert for correction of FIG. 4. FIG. 6 is a cross-sectional view illustrating the use state of a shoe insert for correction of FIG. 4 from the rear direction.
The shoe inserts for correction according to the second exemplary embodiment of the present invention of FIGS. 4 to 6, are identical to the shoe inserts for correction according to the first exemplary embodiment in a manner of comprising a body 10 which is formed in a size supporting only bottoms of a rear-sole portion and a middle-sole portion of a foot, excluding a front-sole portion, and an upper surface 11 which is formed in a manner of supporting bottom by adhering to the bottoms of the rear-sole portion and the middle-sole portion, and a correction means 20 which is disposed at one of an outer side or an inner side of the rear-sole portion on a lower surface 14 of the body. However, the shoe inserts for correction according to the second exemplary embodiment is characterized to provide the correction means which can be coupled to or separated from the lower surface.
This correction means 20 comprises a coupling plate 21 protruding from one of an outer side or an inner side of the rear-sole portion on a lower surface 14 in a manner of crossing back and forth, and a correction member 22 having a coupling recess portion 21′ recessed into an upper surface of the correction member in a manner of crossing back and forth, such that the coupling plate is couple thereto.
Installing the correction member 22 to be coupled to or to be separated on the lower surface 14 of the rear-sole portion by using the coupling plate 21 and the coupling recess portion 21′ is for a user to choose and couple the correction member with right thickness by manufacturing and providing the up-and-down thickness of the correction member in various sizes.
FIGS. 7 a to 7 c are rear views illustrating different examples of shoe insert for correction of FIG. 4.
A shoe insert for correction according to different examples of FIGS. 7 a to 7 c is an example of having an outer side of the up-and-down thickness bigger than that of an inner side by forming the upper surface of the correction member 22, coupled to the outer side of the rear-sole portion of the lower surface 14, to gradually incline upwardly from the inner side to the outer side.
The user may use the shoe insert by coupling the correction member with right thickness according to the downwardly twisted degree of the outer side of the heel to the body 10 by forming the difference of up-and-down thickness between the inner side and the outer side of the correction member in various sizes.
In this case, since only correction member 22 should be manufactured separately, not manufacturing shoe insert for correction itself in various sizes according to the twisted degree of the heel, so it has effect of not wasting a great number of resources and costs since only correction member can be purchased and replaced, not discarding the body, when a new shoe insert for correction is needed after twisted state is being corrected to certain degree.
Meanwhile, using the correction member by coupling the correction member 22 to the outer side of the lower surface 14 of the rear-sole portion of the body 10 was described as an example as above, however, it is not limited to this, so the case of manufacturing the correction member coupled to the inner side of the lower surface of the rear-sole portion when inner side of the heel is twisted downwardly can also belong to the rights of the present invention.
Of course, the up-and-down thickness of the inner side of the correction member should be bigger than that of the outer side corresponding to the downwardly twisted degree of the inner side of the heel when using the correction member 22 by coupling to the inner side of the lower surface of the rear-sole portion.
In addition, the coupling plate 21 is protruded on the lower surface 14 and the coupling recess portion 21′ is formed on the upper surface of the correction member 22, however, the coupling plate can also be formed on the upper surface of the correction member and the coupling recess portion can be formed on the lower surface.
Shoe inserts for correction according to the first and the second exemplary embodiments of the present invention may correct twisted heel more effectively by selecting and using the right ones having a correction means 20 on right location and with right thickness according to the twisted degree and to which side of the heel is twisted.
FIG. 8 is a separation perspective view of a shoe insert for correction according to the third exemplary embodiment of the present invention. FIG. 9 is a perspective view illustrating a lower surface of a shoe insert for correction of FIG. 8. FIG. 10 is a cross-sectional view illustrating the use state of a shoe insert for correction of FIG. 8 from the side.
A shoe insert for correction according to the third exemplary embodiment of the present invention of the FIG. 8 to FIG. 10 is characterized by comprising a body 10, a correction means 20, a coupling recess 30 of a massage member 12, and a slide-preventing means 40.
The body 10, as same as in the first and the second embodiments, is formed to support the bottom by having the upper surface 11 closely adhered to the bottoms of the rear-sole portion and the middle-sole portion, and the edge 10 a excluding the front end portion of the middle-sole portion is extended to a fixed height so that the inner side is in a curved shape. The body further comprises a massage member 12 enabling a smooth blood circulation by stimulating the sole of the foot by being protruded at a portion of an upper surface corresponding to an arcuate portion of the foot, and a great number of air hole 13 formed around the massage member to be penetrated up and down.
A correction means 20 which is disposed at one of an outer side or an inner side of the rear-sole portion, supporting a heel, on a lower surface 14 of a body 10 in a manner of crossing back and forth, and also which is in various up-and-down thicknesses so that users may choose and use the ones having right thickness according to twisted degree of a heel, is identical to the above first and the second exemplary embodiments.
That is, a correction means 20 is disposed at outer side of the rear-sole portion of the lower surface 14 in case where legs are bend in a ‘O’ shape since outer side of a heel is twisted downward and the up-and-down space of inner side of the knee joint becomes smaller than that of outer side of the knee joint, and accordingly the body is selected and placed into a shoe, then the outer side of a heel is lifted when wearing shoes since outer side of the rear-sole portion becomes higher than that of inner side in proportional to the up-and-down thickness of the correction means in case of ‘O’ shaped legs. Then, the up-and-down space of the outer side gets smaller slowly since pressure generated according to the degree how much outer side of a heel is lifted is applied to the outer side of the knee joint, whereas, the up-and-down space of the inner side of the knee joint where pressure is not affected gets bigger, and thus the up-and-down spaces of outer and inner side of the knee joint are corrected to be even and ‘O’ shaped legs become balanced legs.
On the other hand, the correction means 20 is disposed at inner side of the rear-sole portion of the lower surface in case where legs are bend in a ‘X’ shape since inner side of a heel is twisted downward and the up-and-down space of inner side of the knee joints becomes bigger than that of the outer side of the knee joint, and accordingly the body is selected and placed into a shoe, then the inner side of a heel is lifted when wearing shoes since inner side of the rear-sole portion becomes higher than that of outer side in proportional to the up-and-down thickness of the correction means in case of ‘X’ shaped legs. Then, the up-and-down space of the inner side gets smaller slowly since pressure generated according to the degree how much inner side of a heel is lifted is applied to the inner side of the knee joint, whereas, the up-and-down space of the outer side of the knee joint where pressure is not affected gets bigger, and thus the up-and-down spaces of outer and inner side of the knee joint are corrected to be even and ‘X’ shaped legs become balanced legs.
A coupling recess 30 is recessed into a portion of an upper surface 11 of the body 10 corresponding to an arcuate portion of the foot, and comprises an upper coupling portion 31 having an inner circumferential surface with a great diameter and a lower coupling portion 32 having a diameter shorter than that of the upper coupling portion and formed directly below the upper coupling portion in a connected manner.
A massage member 12 comprises a body portion 12 a downwardly extending with a diameter as great as being closely inserted into the upper coupling portion 31, an upper surface portion 12 b extending from an upper side of the body portion in a curved shape, and an adhering portion 12 c downwardly extending from a lower surface of the body portion 12 a to have a diameter as great as being closely inserted into the lower coupling portion 32.
The massage member 12 is formed of one of soft synthetic resin, rubber or rubber magnet each having its own elasticity.
Therefore, when coupling the massage member 12 to the coupling recess 30, the body portion 12 a is firmly coupled to the upper coupling portion 31 and the adhering portion 12 c to the lower coupling portion 32, and at the same time the upper surface portion 12 b is exposed to the upper part of the body 10.
When wearing shoes by placing the body 10 coupled with a massage member 12, the massage member is kept firmly since the massage member is pressed by the weight, so it is not separated when walking or running.
Also, when forming the massage member 12 with a rubber magnet, the massage effect increases due to the magnet.
A slide-preventing means 40 is formed of one of a frictional protrusion downwardly protruding in an integral form from the lower surface 14 with begin spaced from the front end portion of the middle-sole portion by a predetermined interval, or soft synthetic resin or rubber, in a shape of a thin band on the front end portion of the middle-sole portion.
When wearing shoes with the body 10 installed with the slide-preventing means 40, a strong frictional force occurs since the body is compressed to the bottom of the shoe due to the weight of the user.
Then, it is prevented for the body 10 from being slid forward since a strong frictional force occurs due to the slide-preventing means when walking or running with shoes, thus providing good use state and wearing comfort.
The reason why slide-preventing means is formed as above is that it cannot be completely prevented for the body from being slid forward due to the wearing stated of the shoes and the walking habit, only with body 10 extending the edge 14 excluding the front end portion of the middle-sole portion to the fixed height so that the inner side is in a curved shape thus preventing the body from being slid forward since the heel is caught on the inner and the outer portion of the rear-sole portion and the middle-sole portion.
FIG. 11 is a perspective view of a separation of a shoe insert for correction according to the fourth exemplary embodiment of the present invention. FIG. 12 is a floor plan of combined shoe insert for correction of FIG. 11. FIG. 13 is a cross-sectional view illustrating the use state of a shoe insert for correction of FIG. 11 from the side.
The shoe insert for correction according to the fourth embodiment of the present invention of FIG. 11 to FIG. 13 comprises a body 10, a correction means 20, a coupling recess 30 of a massage means 12, and a slide-preventing means 40 as it is in the above fourth embodiment.
The slide-preventing means 40 has a size as great as supporting the entire sole, and is formed in a shape of an insole having a supporting jaw 43 formed at a boundary between a front-sole portion 41 and a rear portion 42, the boundary formed by making the rear portion 42 thinner than the front portion 41, to support a front end portion of the body 10 and thus prevent the body from being slid forward while using the slide-preventing means 40.
The supporting jaw 43 is formed thin by compressing the rear portion 42 more than the front portion 41 in the process of manufacturing normal shoe insert by pressing and cutting the synthetic resin sheet formed in fixed thickness to have a cushion with the press.
It provides good use state and wearing comfort because the body is not slid forward since the front end portion is adhered closely to the supporting jaw due to the weight when wearing shoes having the front end portion of the body 10 supporting the supporting jaw 43 after placing the slide-preventing means 40 into the bottom of the shoe.
In addition, it is not necessary to manufacture the shoe inserts for correction in various sized since by marking the cutoff lines 44 by the foot size on front end portion of one of upper surface or lower surface of the slide-preventing means 40, anyone can purchase and cut and use the shoe inserts.
FIG. 14 is a front view of different examples of massage member applied to shoe inserts for correction according to the third and fourth embodiments of the present invention.
Anyone can have enough massage effect by purchasing and using the shoe inserts for correction with the massage member 12 with right height, wherein the massage member 12 according to different example of FIG. 14 has different depth of arcuate portion of the foot which contacts with the upper surface portion 12 b according to the user so the height h from the body portion 12 a to the upper surface portion can be formed in various sizes.
By selecting and using the massage member 12, the body 10 is not needed to be manufactured in various sizes since all you have to do is to purchase the massage member with right size, if necessary, and couple to the coupling recess, thus providing effects of not wasting resources and costs.
The shoe inserts for correction according to the third and the fourth exemplary embodiments of the present invention correct the twisted heel efficiently by selecting and using the inserts comprising correction means 20 on right location and with the right thickness according to which side of heel is twisted and the twisted degree and, at the same time, may gain massage effect and good wearing comfort since a body 10 is not being slid forward.
