Description

Toe corrector and manufacturing method thereof

The present invention relates to a toe corrector and a method of manufacturing the same, and more particularly, to a toe corrector that is manufactured to fit the shape of a user's foot and can effectively correct a deformed toe shape, and a manufacturing method thereof.

In general, hallux valgus refers to a disease in which the metatarsophalangeal joint, which is the root part of the big toe, protrudes and the big toe is bent toward the center, and the shape of the foot is deformed. Hallux valgus may occur congenitally, but most of it is acquired due to the fact that the big toe is pushed in the shoe while repeatedly wearing shoes with high heels and narrow fronts. When you walk or stand for long periods of time in high heeled, narrow toe shoes, the high heel shifts the load on your body to the front of your foot, which in turn puts an excessive load on the front of your foot or your toes. This can change the shape of the feet and toes. In addition, when the width of the front part of the shoe is narrow, the pressure applied from both sides and the upper side of the foot increases, so that the shape of the foot and toes may be deformed. When such hallux valgus occurs, the root of the big toe is in continuous contact with the shoe, so the skin thickens and a bunion that causes bursitis between the skin and bone is accompanied. will cause In addition, when hallux valgus occurs, the big toe, which should provide propulsion during walking, does not perform its original role, so calluses are formed on the remaining toes and soles of the feet, causing inflammation and pain. It can also cause skin diseases such as athlete's foot or eczema. Therefore, various toe corrective devices for forcibly spaced apart between the big toe and the second toe have been proposed, but the conventional orthodontic instruments are ready-made products and thus do not provide corrective force suitable for the user's deformed foot shape, resulting in poor correction effect. There is this.

Accordingly, there is a need for a device that is manufactured to fit the shape of the user's foot and can effectively correct the deformed toe shape.

The toe correction device 1 according to an embodiment of the present invention is a device for correcting the deformation of the toes due to hallux valgus by forcibly spaced apart between the big toe and the other toes.

Since the toe corrector 1 is custom-made to fit the shape of the user's foot, it is possible to provide corrective force corresponding to the shape of the deformed foot for each user, thereby maximizing the toe correction effect. In addition, since the toe correction device is formed in the form of a cap made of a plurality of resin layers and covered on the front end of the foot, it is possible to walk comfortably while wearing it, and to wear shoes after wearing, so that continuous correction is possible. .

Hereinafter, with reference to FIGS. 2 to 4, it will be described in more detail with respect to the toe correction device (1).

Figure 2 is an enlarged perspective view of the toe correction device of Figure 1, Figure 3 is a view for explaining the structure of the foot, Figure 4 is a longitudinal cross-sectional view of the foot fixing part.

The toe correction device 1 according to the present invention includes a foot fixing part 10 , a first toe fixing part 20 , a second toe fixing part 30 , and a spacing maintaining part 40 .

The foot fixing part 10 is formed in a ring shape surrounding the sole and the back of the foot to fix the foot, and may be made of a hard material having elasticity. More specifically, the foot fixing part 10 may be made of a resin including at least one of urethane, carbon fiber reinforced resin (auxiliary agent), silicone, and other resins. For example, the foot fixing part 10 may be formed of urethane, or formed by mixing urethane with a carbon fiber-reinforced resin as an auxiliary agent), or may be formed by mixing urethane and silicone. When the fixing part 10 is formed by mixing two materials, the fixing part 10 may form a hard material or a semi-hard material depending on the mixing ratio of each material. Since the foot fixing part 10 is formed of a hard material having elasticity, it is elastically deformed when an external force is applied while maintaining the external shape, and can be elastically restored when the external force is removed.

The foot fixing part 10 is composed of an entrance part 10a through which the toes enter and exit, and a fixing part 10b for fixing the sole and the back of the foot, and the entrance part 10a may be formed more flexible than the fixing part 10b. . For example, the inlet portion 10a and the fixing portion 10b are made of the same resin layer on the surface in contact with the foot, and the fixing portion 10b may be formed by stacking more resin layers than the inlet portion 10a. have. At this time, as shown in (a) of FIG. 4 , the inlet portion 10a is formed to be more flexible than the fixed portion 10b by keeping the step portion and the resin layer constituting the fixed portion 10b in an empty state. Alternatively, as shown in (b) of FIG. 4 , a separate soft material 11 is laminated on the stepped portion and the resin layer constituting the fixed portion 10b to be formed more flexible than the fixed portion 10b. have. Since the inlet portion 10a is formed to be more flexible than the fixing portion 10b, the operation of putting the foot fixing portion 10 on and taking off the foot can be easily performed, and discomfort can be minimized in a state of being worn on the foot. Since the inlet portion 10a is coupled with the anti-slip portion 60 to the inner surface in contact with the sole, slipping can be minimized while worn on the foot. The material of the slip prevention part 60 is not limited, but may be formed of a material having friction, such as urethane or silicone. The foot fixing part 10 has a first toe fixing part 20 and a second toe fixing part 30 extending respectively.

The first toe fixing part 20 is a part extending from the foot fixing part 10 to fix the big toe, and may be integrally formed with the foot fixing part 10 .

The first toe fixing part 20 is closed at the end to surround the entire big toe and can be accommodated therein. By accommodating the first toe fixing part 20 inside the entire big toe, it is possible to provide an appropriate corrective force to the deformed big toe. In other words, as shown in (a) of FIG. 3, an external force is applied inward to the root part of the big toe protruding outward, that is, the metatarsophalangeal joint, and at the same time, an external force is applied to the big toe bent toward the center. The position of the big toe can be corrected.

The second toe fixing part 30 is a part extending from the foot fixing part 10 to fix the remaining toes, and may be integrally formed with the foot fixing part 10 . That is, for convenience of explanation, the foot fixing part 10 and the second toe fixing part 30 are separately described, but the foot fixing part 10 and the second toe fixing part 30 are also integral structures with each other, and toe correction. Each area of the device 1 may be partitioned. As shown, the second toe fixing part 30 may be accommodated inside while surrounding the entire remaining toes, and the ends may be opened so that one or more of the tips of the remaining four toes may be exposed to the outside.

Between the first toe fixing part 20 and the second toe fixing part 30, a gap maintaining part 40 may be formed. The interval maintaining part 40 is to maintain the interval between the first toe fixing part 20 and the second toe fixing part 30, from the first toe fixing part 20 and the second toe fixing part 30 It may be extended to form a curved surface (40a) toward the foot fixing portion (10). By forming the gap maintaining part 40 between the first toe fixing part 20 and the second toe fixing part 30, the big toe and the remaining toes are forcibly spaced apart so that the position of the big toe can be corrected.

The foot fixing part 10, the first toe fixing part 20, the second toe fixing part 30, and the spacing maintaining part 40 are formed in the form of a cap made of a plurality of resin layers to form the front end of the foot. can be covered on Here, the front end of the foot may refer to a front portion extending from the toe end (A) and covering the toe joint (B), as shown in (b) of FIG. 3 . The foot fixing part 10, the first toe fixing part 20, the second toe fixing part 30, and the spacing maintaining part 40 are formed in a cap shape made of a plurality of resin layers and covered by the front end of the foot. , it has the advantage of being able to walk comfortably while wearing it, as well as wearing shoes after wearing it, so that continuous correction is possible. On the other hand, since the longer the length of the foot fixing part 10 protruding to the outside of the toe joint (B), the lower the fit, it is preferable to minimize the length of the foot fixing part 10 protruding to the outside of the toe joint (B).

In addition, a plurality of ventilation holes 50 may be formed through the foot fixing part 10 , the first toe fixing part 20 , and the second toe fixing part 30 . By forming a plurality of ventilation holes 50 through the foot fixing portion 10, the first toe fixing portion 20, and the second toe fixing portion 30, the toe correcting device 1 is formed in the form of a cap, so that the feet Even if it is covered with the front end, ventilation is easy, so it is possible to minimize the occurrence of skin diseases such as athlete's foot and eczema due to moisture. Although the drawing shows that three ventilation holes 50 are formed through the upper surface of the foot fixing part 10, the present invention is not limited thereto, and the number and arrangement of the ventilation holes 50 may be variously modified.

Hereinafter, with reference to FIGS. 5 and 6, it will be described in more detail with respect to the toe corrector 1 according to another embodiment of the present invention.

5 is an enlarged perspective view of a toe corrector according to another embodiment of the present invention, and FIG. 6 is an operational view showing a state in which the elastic deformation range of the spacing maintaining unit is varied by the corrector.

Toe correction device (1) according to another embodiment of the present invention is the corrector 70 is inserted into the gap maintaining portion (40). The toe corrector 1 according to another embodiment of the present invention is substantially the same as the above-described embodiment, except that the corrector 70 is inserted into the gap maintaining unit 40 . Therefore, it is mainly described, but unless otherwise stated, the description of the remaining components is replaced with the above-mentioned matters.

A corrector 70 may be inserted into the gap maintaining unit 40 . The corrector 70 is for limiting the elastic deformation range of the interval maintaining unit 40, it may be inserted into the interval maintaining unit 40 to be fixedly coupled to the curved surface (40a). The material of the corrector 70 is not limited, but may be formed of, for example, a material harder than the foot fixing unit 10 such as silicone, plastic, or the like. When the corrector 70 is not inserted into the gap maintaining part 40, as shown in (a) of FIG. 6, the elastic deformation range (H1) of the gap maintaining part 40 becomes longer, so that the toes are fixed As the magnitude of the force is reduced, the effect of correcting the position of the toe is reduced, and, of course, the big toe is maintained in a bent state, thereby increasing the fatigue of the foot. When the corrector 70 is inserted into the gap maintaining part 40, as shown in (b) of FIG. 6, the elastic deformation range (H2) of the gap maintaining part 40 is shortened, so the force of fixing the toes As the size of the toe increases, the effect of correcting the position of the toes is increased, and the fatigue of the feet can be reduced because the big toe is kept in an extended state. Although the figure shows that the corrector 70 is formed to correspond to the shape of the gap maintaining unit 40, it is not limited thereto, and the shape of the corrector 70 may be variously modified.

Hereinafter, with reference to FIG. 7, it will be described in more detail with respect to the toe corrector 1 according to another embodiment of the present invention.

7 is a perspective view showing an enlarged toe correction device according to another embodiment of the present invention.

In the toe correction device 1 according to another embodiment of the present invention, the end of the second toe fixing part 30 is opened so that the remaining toes are exposed to the outside. The toe correction device 1 according to another embodiment of the present invention is substantially the same as the above-described embodiment, except that the end of the second toe fixing part 30 is opened and the remaining toes are exposed to the outside. Therefore, it is mainly described, but unless otherwise stated, the description of the remaining components is replaced with the above-mentioned matters.

The second toe fixing part 30 has an open end so that one or more of the tips of the remaining four toes can be exposed to the outside. The end of the second toe fixing part 30 is opened and the remaining toes are exposed to the outside, so that ventilation is easier, and thus the occurrence of skin diseases due to moisture can be effectively prevented. In the drawing, the end of the second toe fixing unit 30 is fully opened and all of the remaining toes are exposed to the outside, but the present invention is not limited thereto, and only some of the ends of the second toe fixing unit 30 are opened and the rest. Some of the toes may be closed and only some of the remaining toes may be exposed to the outside.

Hereinafter, with reference to FIGS. 8 and 9, it will be described in more detail with respect to the manufacturing method of the toe correction device (1).

8 is a flowchart illustrating a method of manufacturing a toe corrector, and FIG. 9 is a view for explaining a manufacturing step of a plaster model.

The manufacturing method of the toe correction device according to the present invention comprises the steps of (A) manufacturing a mold by solidifying a mold raw material at the front end of the foot after aligning the toes, and (B) step of producing a plaster model by injecting gypsum into the mold And, (C) step of coating paraffin on the gypsum model, (D) step of coating and curing the liquid resin on the paraffin-coated gypsum model to prepare a prototype of the orthodontic device, and paraffin from the gypsum model on which the prototype of the orthodontic device is formed (E) of removing the orthodontic device prototype.

First, after aligning the big toe and the remaining toes, the mold material is solidified at the front end of the foot including the toes to manufacture a mold (step (A)). For example, a member such as a rubber band is hung on the big toe bent toward the center and pulled outward to align the big toe so that the big toe is spaced from the other toes, and the front end of the foot including the aligned big toe and the remaining toes A mold can be manufactured by solidifying a mold raw material, which is an impression material, such as alginate, silicone, or rubber.

When the mold is manufactured, the plaster is injected into the mold and solidified to produce a plaster model corresponding to the shape of the user's foot (step (B)). Referring to FIG. 9 in more detail, first, after manufacturing a plaster model corresponding to the shape of the foot, as shown in FIG. 9 (a), additional plaster is injected between the remaining toes of the plaster model. and solidified to integrally form the remaining toe parts. When the remaining toe parts of the plaster model are integrated, as shown in FIG. As the tip of the remaining toe part is cut, a plaster model of the shape as shown in FIG. 9(c) may be manufactured.

When the gypsum model is produced, paraffin is coated on the outside of the gypsum model (step (C)), and the paraffin can be poured and coated on the outside of the gypsum model, or the gypsum model can be dipped in paraffin and coated. At this time, by adjusting the thickness of the paraffin coated on the gypsum model, it is possible to adjust the clearance between the user's foot and the final completed orthodontic device prototype. For example, if the thickness of paraffin coated on the gypsum model is increased, the gap between the user's foot and the prototype of the brace increases, so that the prototype of the brace may fit slightly loosely on the foot. If the thickness is made thin, the clearance between the user's foot and the original orthodontic device is reduced, so that the original orthodontic device may fit somewhat tightly to the foot. It is possible to adjust the clearance between the user's foot and the original orthodontic device, so that it can be manufactured according to the user's needs, thereby improving the fit and satisfaction.

When the paraffin is coated, a liquid resin is coated on the paraffin-coated gypsum model and cured to prepare a prototype of the orthodontic device (step (D)). At this time, the process of coating and curing the liquid resin may be repeated to form a prototype of the orthodontic device in the form of a cap composed of a plurality of resin layers. The thickness of the resin layer can be varied according to user needs, and the elasticity and hardness of the orthodontic device can be adjusted by adjusting the thickness of the resin layer. In addition, in the circular orthodontic device, the process of coating and curing the liquid resin is repeated more than the inlet part 10a through which the toes enter the fixed part 10b for fixing the sole and the instep of the foot, so that the inlet part 10a is fixed to the fixed part ( 10b) can be made more flexible. If necessary, after coating the liquid resin, the inlet portion 10a may be coated with a material softer than the liquid resin to make the inlet portion 10a more flexible. Since the inlet portion 10a is formed more flexible than the fixed portion 10b, it is easy to put on and take off the circular orthodontic device on the foot, and it is possible to minimize the discomfort in the state of being worn on the foot.

When the original orthodontic appliance is manufactured, the original orthodontic appliance is separated by removing the paraffin by immersing the gypsum model on which the orthodontic original is formed in warm water (step (E)). If the gypsum model with the original orthodontic device is immersed in hot water at about 45~65℃, the paraffin melts and a gap is formed between the gypsum model and the original orthodontic device, so the original orthodontic device can be easily separated from the gypsum model.

When the original orthodontic appliance is separated from the plaster model, a plurality of ventilation holes 50 may be formed in the original orthodontic appliance. When the ventilation hole 50 is formed, it is possible to minimize the occurrence of skin diseases such as athlete's foot and eczema due to moisture because ventilation is easy. In addition, by combining the anti-slip portion 60 formed of a material having friction on the inner surface of the inlet portion 10a of the circular shape of the orthodontic device, it is possible to minimize slippage when worn. In addition, by inserting and combining the corrector 70 in the gap maintaining part 40 formed between the first toe fixing part 20 for fixing the big toe and the second toe fixing part 30 for fixing the remaining toes, It is possible to limit the elastic deformation range of the gap maintaining unit 40 . When the elastic deformation range of the gap maintaining unit 40 is limited, the magnitude of the force for fixing the toes is increased, so that the position correction effect of the toes is increased, and the big toe is maintained in an extended state, thereby reducing the fatigue of the foot.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those of ordinary skill in the art to which the present invention pertains can realize that the present invention can be embodied in other specific forms without changing the technical spirit or essential features. you will be able to understand Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
