Description

Protecting device for toe}

The present invention relates to a toe protector, and relates to a toe protector to prevent blisters from occurring.

During long walking and vigorous exercise, such as mountain climbing and trekking, blisters form in various places on the feet. For example, new shoes that do not fit on the bottom of the foot will cause blisters on the soles of the feet, and if the shoes are too small or loose, blisters will appear on the heels.

As a patent that prevents blisters on the heels, technologies such as Korean Patent Publication No. 20150029603 and the manufacturing method of a side correction pad for rock shoes have been suggested in the technology to protect the heels.

Another factor that causes walking discomfort is blisters on the toes. Later, this is called a toe blister. Since the toe blister causes discomfort every time the foot is stepped, the technology to improve these problems is only introduced on the Internet, although a technique for improving these problems is to fit a finger on the toe. These toe thimbles are nothing more than protecting the toes from breaking.

Republic of Korea Patent Publication No. 20150029603, Manufacturing method of side correction chad for rock paintings

The present invention is proposed under the above-described background, and proposes a toe protection device capable of preventing blisters occurring on the toes and capable of painlessly removing already formed blisters.

The present invention proposes a toe protection device that can be comfortably used without feeling foreign to other toes adjacent to the affected toe as well as to the affected toe.

The present invention proposes a toe protection device that can be adaptively used in the patient and the affected area.

In the toe protection device according to the present invention, a base corresponding to the branching portion of the toe having an opening into which the toe is fitted: an end placed on the opposite side of the base: and between the base and the end, surrounding the toe in a hollow, left and right An enclosure that absorbs the torsion force applied to the blister candidate of the toe by providing a raised portion in which one side is provided thicker than the other side based on the direction is included. According to the present invention, the occurrence of blisters on the toes is suppressed by the raised portion, and pain caused by the generated blisters can be reduced. Since the enclosure surrounds the toe, there is an advantage that a separate support member for the toe protection device is not required.

The raised portion is formed on the left side of the toe for the toe of the right foot, and is formed on the right side of the toe for the left toe, and can be used on the toes of both feet.

The raised portion is raised inward from the enclosure to increase the thickness of the enclosure at a corresponding portion, so that other adjacent toes are not indirectly received, and a feeling of foreign body received by adjacent toes can be reduced.

The end may be opened to reduce foreign body sensation and allow sweat to evaporate.

A wing portion extending from the upper side of the base portion in the instep direction is included, so that even if sweat occurs during long walking, the rotation of the toe protector can be prevented.

The wing portion extends in the interval between the toes, thereby preventing rotation of the toe protector and reducing a feeling of foreign body.

The upper part of the enclosure is provided as a straight portion, and the lower part of the enclosure is provided in a curved shape similar to the soft cells of the toe, and is provided similarly to the shape of the toe, so it is convenient.

The enclosure is provided with at least two holes to allow sweat to be discharged, so that odor due to sweat deposition in the protective device can be prevented.

The raised portion is provided only on a portion of the inner surface of the enclosure, thereby reducing the feeling of foreign body and pressure received by other adjacent toes.

In the toe protection device according to the present invention of the other aspect, the base corresponding to the branching portion of the toe having an opening into which the toe is fitted: an end placed on the opposite side of the base: and between the base and the end, the toe is hollowed out. Surrounding, at the bottom, the side facing the big toe is provided thicker than the side facing the little toe, and the enclosure that absorbs the torsion force applied to the blister candidate of the toe absorbs the force applied to the toe during a person's walking Thus, it can absorb the force exerted on the toes during walking and running. ,

The enclosure may be provided soft. For example, silicone can be used.

According to the present invention, blisters on the toes that may occur due to accumulation of steps can be prevented, and blisters that have already occurred can be quickly removed.

According to the present invention, there is no foreign body sensation with respect to the other toes adjacent to the toe when it is attached to a blistered toe, and discomfort of the other adjacent toes can be eliminated.

According to the present invention, a function is adaptively given only to the affected area by grasping the reason why blisters occur due to the accumulation of steps and improving it, so that there is no inconvenience in use.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. The spirit of the present invention is not limited to the embodiments, and those skilled in the art who understand the spirit of the present invention can easily propose other embodiments included within the scope of the same idea by adding, changing, deleting, and adding components. Although there may be, it will be said that this is also included within the scope of the idea of the present invention.

Prior to the description of the examples, the results of the inventor's research on the cause of blisters on the toes will be described.

First, as a first factor, since a person walks upright, a large load is applied to a single foot, and all the loads are concentrated on the toes at a specific point in time during the movement of walking. For example, the toe of one foot is subjected to the greatest load just before the heel of the other foot closes to the foot.

As a second factor, a person's feet are not aligned in a straight line, but in many cases, both feet are placed obliquely toward the outside at a predetermined angle. This may have a stable effect for the expansion of the center of gravity and maintenance in a standing position, but it causes a dynamic characteristic in the toe and acts as a problem of increasing fatigue to the toe.

Specifically, the second factor creates a discrepancy between the direction the pedestrian goes and the direction the foot is facing, and creates a force that pushes the toe as a whole in one direction.

Specifically, the moment when the first factor acts the most, that is, just before the heel of the other foot closes to the foot, and the moment when the maximum force is applied to one toe (hereinafter referred to as the maximum torsion moment), the toe is pushed. Force can act the most. At this time, the direction of the force generates a torsional force in which the sole of the foot rotates outward in the direction of travel around the ankle. Accordingly, a clockwise torsion occurs in the right foot when viewed from above, and a counterclockwise torsion occurs in the left foot when viewed from above. Such a phenomenon is a phenomenon that can appear characteristically in a person's body structure.

The maximum torsion moment creates a repetitive impact on the toe and eventually becomes a factor causing blisters on the toe.

1 is a schematic view of a portion where the toe is visible at the end of the right foot.

On the other hand, the viewpoints of all drawings were based on the viewpoint of a person with a blister on the toe, not the objective observer standard. Therefore, in understanding the drawings, the cross section of the toe can be understood as a view observed from the rear side in the traveling direction.

Referring to Figure 1, 1 is the largest toe and 5 is the smallest toe. In addition, the dotted line in the arrow indicates the direction of travel during walking, and the solid line indicates the direction of the torsion force.

2 shows the direction of the force applied to each toe of the right foot when the torsion force is applied. Referring to FIG. 2, when a person walks, the torsion force generated by touching the floor 6 causes the toe to be pushed to the right. At this time, since the toe bone is in the center of the toe, the soft cell tissue surrounding the toe force bone is inevitably deformed.

3 is a part showing a position at which a toe is deformed by the torsion force. Referring to FIG. 3, the hatched part indicates a place where the soft cell tissue of each toe is deformed and filled when the torsion force is applied. In other words, when the torsion force is applied, the soft cell tissue is filled to the hatched area, and when there is no torsion force, the toe returns to its original state.

If this walking motion is repeated, eventually the soft tissue of the toe is deformed. In particular, epidermal cells are separated, and fluid leaks and toe blisters are formed. Here, the toe blister mainly occurs at the most tip of the toe. This is because the load is concentrated in the corresponding portion due to the first factor and the second factor.

4 is a view showing a state in which the soft cell tissue of the toe is deformed due to continued walking.

Referring to Figure 4, it can be seen that the repeated load applied to each toe creates a deformation of the soft cell tissue of the toe, and blister candidates (21) (31) (41) (51) have occurred. Among the blister candidates, actually developing to a blister depends on a person's walking habit or surgical form, but can be seen mainly in the fourth toe (4) and the third toe (3).

Here, the blister candidate corresponds to the convex portion located immediately below the tip of the toe. For example, it may be adjacent to the area where the first joint of the toe tip is located. Of course, the exact location of the blister candidate may vary slightly from person to person, but it can be seen that it is placed right inside the tip. In the present disclosure, the position of the blister candidate is an important point that flows through the content of the specification, and is preferably defined only by the content of the present disclosure.

After a blister on the toe occurs, it causes great discomfort to the pedestrian, so it reaches the point where it is impossible to exercise further.

The embodiment is proposed under the above-described background, and may be said to be a toe protection device that does not cause blisters on the toes or can comfortably remove blisters that have occurred on the toes without pain.

5 is a perspective view of a toe protection device according to an embodiment.

Referring to FIG. 5, the toe protection device according to the embodiment includes a base having an opening 100 as an inlet end at which a toe is inserted, an end 110 provided at the opposite side of the inlet end, and the base and end An enclosure 120 surrounding the toe is included between the 110. The inside of the enclosure is empty so that a toe can enter the enclosure so that the inside of the enclosure can be interviewed on the toe. To this end, the material of the toe protector is preferably a material such as soft silicone.

The user may insert a toe through the opening 100 and insert the base so that the toe contacts the hem where the toes are branched from each other. That is, the total length L1 of the toe protector may be provided similar to the length of each toe.

The end 110 may be closed or may be open. When the end 110 is open, effects such as ventilation and reduction of foreign body sensation due to toe interference can be obtained. When the end 110 is closed, there is an advantage in that the insertion position of the toe protection device is more accurately determined and the position does not change even while walking.

The shape of the enclosure 120 of the toe protector may be provided with the base end (S1) and the tip (S3) identical to the original shape of the toe. On the other hand, the working portion S2 in the approximately middle may be provided with a raised portion so as to push the blister candidates 21 to 51 inward. The raised portion may correspond to a lower left portion of the enclosure 120. The lower left portion of the inner space of the enclosure, which is hatched by a solid line in FIGS. 6 and 7, may correspond thereto.

The raised portion is one side for thickening the enclosure corresponding to the lower side of the toe so that the pushing phenomenon that causes the toe blister does not reach the toe at the position where the toe blister occurs.

Even when the torsion force is applied, the bulging portion may play a role of removing the blister candidate in the first place, and apply a weak pressure to the entire range of blisters that have already been formed so that the blisters can be quickly removed.

Compared to the base end (S1) and the tip (S3), the diameter of the enclosure 120 of the toe protector may be provided with the action portion (S2) largest.

Not only the raised part is provided inside the working part S2, but also wing parts 121 and 122 are provided outside the toe to prevent the blister candidate from becoming a blister.

6 is a cross-sectional view of a working portion according to an embodiment.

6, between the adjacent toe on the side where the blister candidate is generated and the toe on which the toe protector is mounted, the thickness of the enclosure is provided to be thick so that the enclosure absorbs the torsion force so that the blister candidate becomes a blister. Can be prevented. This prevents blisters from forming on your toes. Here, the portion where the enclosure becomes thick corresponds to the place where the blister candidate is placed, and the lower left and right sides of the enclosure may correspond.

Inside the enclosure 120, a raised portion is provided in a shape that is raised compared to other portions. Outwardly of the raised portion, one wing portion 121 extends outward. The wing portion 121 may be provided on the lower side of the enclosure. In this embodiment, the wing portion 121 may be provided outside the raised portion. The wing part becomes one side for thickening the enclosure so that the pushing phenomenon causing the toe blister does not reach the toe at the location where the toe blister occurs.

The wing portion 121 has a shape that becomes thinner toward the outside so that adjacent toes can be comfortably placed without feeling of foreign body. A portion provided thickly between the wing portion 121 and the raised portion may act as a portion that absorbs deformation when the torsion force is applied. Therefore, blister candidates 21 to 51 on the toes may not occur from the beginning. The lower surface of the wing portion 121 may be provided flat.

In order to further obtain the above features, the upper portion of the wing portion 121 may be provided with a first seating portion 124 in which the inflection direction is concave upward in the opposite direction to the other portion of the enclosure, and the side portion of the adjacent toe is placed. The thickness between the first seating portion 121 and the raised portion may be thick so that no deformation is applied to the blister candidate of the toe, and blisters may not occur. The wing portion 121 may be provided thinner toward the edge portion. A lower portion of the wing portion 121 may provide a second seating portion 123 extending to a lower portion of an adjacent toe. According to this, the second seating portion 123 is provided in a curved surface similar to the outer shape of the adjacent toe to guide the deformation, thereby preventing blisters that may occur on the opposite side of the blister candidate of the adjacent toe.

Since the shape of the wing part 121 corresponds to the adjacent toe, it is possible to prevent the enclosure 120 from rotating on the toe.

For reference, dotted arrows in the drawing indicate adjacent toes.

On the other hand, the reinforcing member 140 is for preventing the enclosure from being twisted or rotated due to the material of the toe protecting device provided in a soft material. The reinforcing member 140 may be achieved by fastening a relatively hard plastic plate to a part to reinforce the wing portion to which the torsion force is applied, or by increasing the thickness of the soft member itself providing an enclosure.

7 is a cross-sectional view of a working portion according to another embodiment.

Referring to FIG. 7, the wing portion is also provided on the opposite side where the raised portion is provided. According to this embodiment, since the other wing part 122 absorbs the torsion force applied to the blister candidate of the toe corresponding to it, it is possible to prevent blisters occurring on the two toes with one toe protection device. .

Therefore, it can be said that the shape of the two wing portions 121 and 122 as a whole is the same.

In the other embodiment, it can be seen that the shapes of the wing portions 121 and 122 are different, because the positions of the wing portions are different from each other. It will be described in more detail with reference to the top view of the toe protector of Figure 8.

Referring to FIG. 8, the directions of the toes (dashed-dotted lines) and the directions for forgetting the blister candidates 21 to 51 (solid lines) are not perpendicular to each other, but intersect each other with an angle alpha. Therefore, this is because the line for forgetting the wing portions 121 and 122 should be provided similarly accordingly.

The inventors who disclosed the above examples made another example for the toe protector by repeatedly manufacturing and wearing a prototype. It will be described in detail below.

The embodiments of FIGS. 5 to 8 have the following problems.

First, there was no problem for people with thin toes, but people with thick toes have a big problem with feeling of foreign bodies in the lower part of the toes such as wings.

Although the wing portion may play a role of preventing the rotation of the toe protection device, the torsion force was applied to the lower side of the toe protection device including the wing portion, and thus there was a case that a force to rotate the toe protection device was applied. . This happened a lot when the toe was sweaty and the toe protector was tightly fitted to the toe.

In the case of sweating in the toe protector, there is a problem in that moisture is deposited on the member constituting the material of the toe protector, resulting in an odor.

It was confirmed that the soft cell tissue of the toe was actually already deformed a lot and had a triangular shape. As such, the toes are in close contact with each other so that they are provided in a triangle, so there is no free space between the toes. Therefore, the toe protection device caused inconvenience to intervene a large volume member in the gap between the toes.

The inventor further studied an embodiment that improves the above-described problem. Here, there is something I want to note. The above improvement occurs only in people who have thick toes and sweat a lot, and those who have thin toes and no sweat are not very problematic. Therefore, it is necessary to refer to the point that the original embodiment can also be preferably used.

9 is a perspective view of a toe protection device according to another embodiment, Figure 10 is a right side view of the toe protection device according to another embodiment. The embodiment of the drawing can be applied to the toe of the right foot.

Contents that are not specifically mentioned in other embodiments may be applied as they are to other embodiments, except for contents that conflict with the contents of the original embodiment or cannot be applied in combination. In the opposite case as well, the content of the other embodiment may be applied to the original embodiment except for content that conflicts with the original embodiment or cannot be applied in combination.

9 and 10, the toe protection device 200 according to another embodiment includes an enclosure 220 provided with an end 110 at one end, and an opening 100 at the other end of the enclosure 220. It includes a wing portion 210 provided on the upper side.

The wing part 210 may extend from the inner end of the toe protection device to the instep. The wing portion 210 extends in contact with the instep where sweat does not occur, so that rotation of the enclosure 220 may be prevented. In other words, when the torsion force is applied during walking, when the enclosure 220 is about to rotate, the left and right ends of the wing portion 210 (the upper and lower ends of the wing portion in FIG. 10) are spaced between the instep and toes. It is possible to prevent the enclosure 220 from rotating by being caught.

The wing part 210 may be a part that the user can grasp when the user inserts the toe protection device according to the embodiment on the toe. Accordingly, the user can conveniently hold the toe protector and wear or remove it from the toe.

At least two holes are perforated in the enclosure 220 and the wing part 210 so that sweat from the toes can be discharged.

The upper portion of the enclosure 220 is provided as a substantially straight portion 230, and may correspond to the shape of an actual toe. Rather than referring to a straight line extending in one direction in a general sense, the straight portion 230 may be understood to include irregularities having a shape corresponding to the lifting and flying of each node of the toe in an engineering and industrial sense.

The lower portion of the enclosure 220 may be substantially provided as a curved portion 240. The curved portion 240 may be provided in a shape similar to the convex lower shape of the end joint of the actual toe. By the curved portion 240, the toe protector maintains a shape corresponding to the shape of the end node where blisters occur at the toe, suppresses the occurrence of blisters as much as possible, and prevents rotation of the toe protector due to the torsion force. can do.

In FIG. 10, a place marked with'insert' in the arrow indicates an opening and indicates the direction in which the toe is inserted.

11 to 16 are cross-sectional views of the toe protection device, which are cut vertically while moving left and right in FIG. 10. 11 is a cross-sectional view of 1-1' of FIG. 10, FIG. 12 is a cross-sectional view of 2-2' of FIG. 10, FIG. 13 is a cross-sectional view of 3-3' of FIG. 10, and FIG. 14 is a 4- 5', FIG. 15 is a cross-sectional view of 5-5' of FIG. 10, and FIG. 16 is a cross-sectional view of 6-6' of FIG.

Referring to FIG. 11, a portion close to the end 110 may be provided such that the thickness of the wall constituting the enclosure 220 is substantially the same or thinner in all directions. For example, at a portion close to the opening 100, the enclosure may be provided in the form of a circular frame.

Referring to FIG. 12, in a position where blisters may occur due to the torsion force, the thickness of the enclosure 220 is increased to provide a raised portion 250. The raised portion 250 may absorb deformation of a portion where blisters may occur, that is, strain, and prevent that the end of the portion where blisters may occur may form a point and protrude.

The raised portion 250 is gradually thickened, and a portion corresponding to the apex of a portion where blisters may occur may be provided in the thickest.

Even if the raised portion 250 is provided, it is formed only on the inner surface portion of the enclosure 220, and the outer surface portion of the enclosure 220 is symmetrical with respect to the left and right direction, and thus may be provided in a substantially circular shape.

Referring to FIG. 13, it may be provided in the same shape as that of FIG. 12.

In the middle of FIGS. 12 and 13, the raised portion 250 may be provided in the thickest shape. Of course, the thickness of the raised portion may be kept the same in the length direction of the toe. This may be provided differently depending on the shape of the toe and the specific aspect of the blisters occurring on the toe. The examples have been presented as providing the middle part most convex.

Referring to FIG. 14, if the position of the raised portion 250 is moved out of the position, the enclosure 220 may be maintained in a shape having the same thickness again. However, since the portion of the toe in FIG. 14 has a portion extending in a straight line up and down, it may be provided in an oval shape extending up and down rather than being provided in a circular shape as shown in FIG. 11.

Referring to FIG. 15, the portion of the enclosure 220 surrounding the toe ends, and the wing portion 210 further extends from the upper side of the enclosure 220 to the rear. The start portion of the wing portion 210 may be provided in a curved shape so as to surround the upper side of the root portion of the toe. The wing part 210 may be further expanded toward the rear. The wing part 210 is sandwiched between the toes, so that rotation of the toe protection device may be prevented.

Referring to FIG. 16, the wing part 210 may be provided in a linear shape as a shape corresponding to a flat instep. As described above, the wing part 210 covers at least a portion of the instep so that rotation of the toe protector may be prevented.

It was confirmed that blisters did not occur when walking was continued by wearing the toe protector of all the above examples.

It was confirmed that when the toe protector of the examples of all the above examples was worn in a state where blisters occurred on the toes, the irritation applied to the blisters disappeared or weakened, so that the pain caused by the blisters disappeared, and it was possible to walk conveniently. However, in this case, it was confirmed that the blister was expanded to the other side of the toe, but the amount of body fluid inside the blister was the same, and only the two-dimensional range of the blister was expanded. Even in this case, there was no difficulty in walking because the pain caused by the blister disappeared at all. In addition, due to the fact that the blister does not grow, it is possible to obtain an effect that the blister is quickly removed.

According to the present invention, blisters on the toes caused by many walking can be conveniently prevented. In addition, since it can be manufactured conveniently at low cost, it can be said that its use is greatly expected.
