Description

Protecting device for toe

The present invention relates to a toe protector, and to a toe protector for preventing blisters from forming on the toes.

During long walking and strenuous exercise, such as climbing or trekking, blisters are formed in various places on the feet. For example, a new shoe that doesn't fit the underside of the foot will cause blisters on the sole of the foot, and blisters will form on the heel if the shoe is too small or too loose.

As a patent for preventing blisters on the heel, Korean Patent Laid-Open Patent No. 20150029603, a method of manufacturing a side correction pad for rock climbing shoes, etc., has been proposed in the technology for protecting the heel.

Another factor that causes discomfort in walking is blisters that occur on the toes. Hereafter, these are called toe blisters. The toe blisters cause inconvenience every time they step, so despite causing great inconvenience to pedestrians, only a technique for improving these problems is introduced on the Internet by inserting a thimble that fits the finger to the toe. These toe thimble only serve to protect the toe from breaking.

Republic of Korea Patent Publication No. 20150029603, manufacturing method of side correction chad for rock climbing

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

The present invention proposes a toe protection device that can be used comfortably without feeling a foreign body not only on the affected toe but also on other adjacent toes.

The present invention proposes a toe protection device that can be adaptively used for patients and affected areas.

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

The raised part 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, respectively.

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

By opening the end, it is possible to reduce a feeling of foreign body and to allow sweat to evaporate.

Wings extending from the upper side of the base to the instep direction are included to prevent rotation of the toe protector even when sweating while walking for a long time.

The wing portion, by extending in the gap between the toes, to prevent rotation of the toe protection device, it is possible to reduce the feeling of foreign body.

The upper portion of the enclosure is provided as a straight portion, and the lower portion 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, which is convenient.

The enclosure may be provided with at least two holes to allow sweat to be discharged, thereby preventing odor due to the deposition of sweat in the protective device.

The raised portion is provided only on 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 another aspect, the base corresponding to the branching part of the toe having an opening through which the toe is fitted: an end placed on the opposite side of the base: and between the base and the end, hollow toe to absorb forces applied to the toes during gait of a person, comprising an enclosure that surrounds, in the bottom portion, provided with a side facing the big toe thicker than the side facing the little toe, comprising an enclosure that absorbs a torsion force applied to the blister candidate of the toe This can absorb the force applied to the toes during walking and running. ,

The enclosure may be provided as flexible. For example, silicone may be used.

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

According to the present invention, there is no feeling of foreign body with respect to other toes adjacent to the toes when worn on the blistered toes, and discomfort of other adjacent toes can also be eliminated.

According to the present invention, by identifying the reason for blistering due to step accumulation and improving it, the function is adaptively given only to the affected part, so 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 suggest other embodiments included within the scope of the same idea by adding, changing, deleting, and adding components. However, it will be said that this is also included within the scope of the present invention.

Prior to the description of the embodiment, the results of the inventor's study on the factors of blisters occurring 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 load is concentrated on the toes at a specific point in time during a walking motion. 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, and the two feet are placed obliquely outward at a predetermined angle in many cases. Although this may have a stable effect for extension of the center of gravity and maintenance of a standing posture, it causes dynamic characteristics in the toes and acts as a problem that further increases fatigue in the toes.

Specifically, the second factor creates a mismatch between the direction in which the pedestrian travels and the direction the foot faces, and creates a force that pushes the toes in one direction as a whole.

Specifically, at the moment when the first factor acts the most, that is, just before the heel of the other foot closes to the foot, the moment when the maximum force is applied to one toe (hereinafter referred to as the maximum torsion moment), the toe is pushed. Force may be the most influential. At this time, the direction of the force generates a torsional force that rotates the sole of the foot outward in the moving direction 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 the human body structure.

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

1 is a view schematically showing a portion where the toes are visible at the tip 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 criterion. Therefore, in understanding the drawing, it can be understood as a drawing observing the cross section of the toe from the back in the traveling direction.

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

Figure 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 there is a toe bone in the center of the toe, the soft cell tissue surrounding the toe force bone is inevitably deformed.

3 is a portion showing a position where the toes are deformed by the torsion force. Referring to FIG. 3 , the hatched portion shows 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 fills the hatched area, and when there is no torsion force, the toe returns to its original state.

If these gait motions are repeated, eventually the soft cell tissue of the toes is deformed. In particular, the epidermal cells are exfoliated, causing body fluid to leak and toe blisters. Here, the toe blister is mainly generated at the most distal joint of the toe. This is because the load is concentrated on the corresponding portion by 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 continuous walking.

Referring to FIG. 4 , it can be seen that the repeated load applied to each toe causes deformation of the soft cell tissue of the toe, and blister candidates 21, 31, 41, and 51 occur. Among the blister candidates, the actual development of blisters depends on a person's gait habits or surgical form, but is mainly seen in the fourth toe (4) and third toe (3).

Here, the blister candidate corresponds to the convex portion located just below the tip of the toe. For example, it may be adjacent to the portion where the first joint of the tip of the toe bone is placed. Of course, the exact location of the blister candidate may vary slightly from person to person, but it is known that it is placed right inside the tip. The location of the blister candidate in the present disclosure is an important point flowing through the contents of the specification, and it is preferable to be defined only by the contents of the present disclosure.

After blisters on the toes, it causes great inconvenience to pedestrians, so they can't do any more exercise.

The embodiment is proposed under the background described above, and it can be said that blisters do not occur on the toes or that the blisters can be removed comfortably without pain.

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

5, the toe protection device according to the embodiment includes a base having an opening 100 as an inlet end at which the toes are inserted, an end 110 provided on the opposite side of the inlet end, and the base and the end The enclosure 120 surrounding the toe between the (110) is included. The interior of the enclosure is empty so that a toe can enter the enclosure and its inner surface can interface with the toe. For this purpose, the material of the toe protection device is preferably a material such as soft silicone.

The user may insert the toe through the opening 100 and insert the base so that the toe touches the hem at which the toes are branched from each other. That is, the total length (L1) of the toe protection device 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 protection device, the base end (S1) and the tip (S3) may be provided the same as the original shape of the toe. On the other hand, the working portion S2 in the center may be provided with a raised portion to push the blister candidates 21, 31, 41, and 51 inward. The raised portion may correspond to the lower left portion of the interior of the enclosure 120 . The lower left portion of the enclosure internal space hatched by a solid line in FIGS. 6 and 7 may correspond thereto.

The raised portion serves as one side for thickening the enclosure corresponding to the bottom of the toe so that the pushing phenomenon causing the toe blisters does not reach the toes at the location where the toe blisters occur.

Even if the torsion force is applied, the raised part serves to remove the blister candidate in the first place, and applies mild pressure over the entire range to the blister that has already formed so that the blister can be quickly removed.

The diameter of the enclosure 120 of the toe protection device, compared to the base end (S1) and the tip (S3), the working portion (S2) may be provided with the largest.

Not only the raised part is provided on the inside of the working part S2, but also the wings 121 and 122 are provided on the outside to prevent the phenomenon that the candidate blisters the toes.

6 is a cross-sectional view of an operating part according to an embodiment.

Referring to FIG. 6 , between the adjacent toe on the side where the blister candidate occurs and the toe on which the toe protection device is mounted, the thickness of the enclosure is provided so that the enclosure absorbs the torsion force so that the blister candidate becomes a blister can be prevented This can help prevent blisters from forming on your toes. Here, the thickened portion of the enclosure corresponds to a place where the blister candidate is placed, and may correspond to the lower left and right sides of the enclosure.

A raised portion is provided on the inside of the enclosure 120 in a shape that is raised compared to other portions. One wing part 121 extends outward from the raised part. The wing portion 121 may be provided on a lower portion of the enclosure. In this embodiment, the wing portion 121 may be provided on the outside of the raised portion. The wing portion serves as a one-way method for thickening the enclosure so that the pushing phenomenon causing the toe blisters does not reach the toes at the location where the toe blisters occur.

The wing portion 121 has a shape that becomes thinner toward the outside so that the adjacent toes can be comfortably placed without a foreign body feeling. A thick portion provided between the wing portion 121 and the raised portion may act as a portion for absorbing deformation when the torsion force is applied. Therefore, blister candidates 21, 31, 41, and 51 in the toes may not occur from the beginning. A lower surface of the wing part 121 may be provided flat.

In order to further obtain the above characteristics, 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 part 124 and the raised part is provided to be thick so that no deformation is applied to the blister candidates of the toes, 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 part 123 is provided with 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 in advance.

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

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

On the other hand, the reinforcing member 140 is to prevent the enclosure from being twisted or rotated due to the material of the toe protection device provided as soft. 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 the enclosure.

7 is a cross-sectional view of an operating part according to another embodiment.

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

Accordingly, the shape of the two wing portions 121 and 122 may be said to be the same as a whole.

It can be seen that the shapes of the wing parts 121 and 122 in the other embodiments are different from each other, because the positions of the wing parts are different from each other. It will be described in more detail with reference to the plan view of the toe protection device of Figure 8.

Referring to FIG. 8 , the direction of the toes (dotted-dotted line) and the direction of forgetting the blister candidates 21, 31, 41, and 51 (solid line) intersect at an angle alpha, not at right angles to each other. Therefore, the line for forgetting the wing portions 121 and 122 should be provided accordingly.

The inventor who disclosed the above embodiment made another embodiment with respect to the toe protector by repeating the production and wearing of the prototype. It will be described in detail below.

5 to 8 had the following problems.

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

Although the wing portion may serve to prevent rotation of the toe protector, as the torsion force is applied to the lower side of the toe protector including the wing portion, there is a case where a force to rotate the toe protector is rather applied. . This happened a lot when the toes were sweating and the toe protectors were tight on the toes.

When the toe protector sweats, moisture is deposited on the member constituting the material of the toe protector, and there is a problem such as smell.

The soft cell tissue of the toe was actually deformed a lot, and it could be confirmed that it had a triangular shape. Since the toes are in close contact with each other enough to be provided in a triangle as described above, there is no free space between the toes. Accordingly, in the toe protection device, it was rather inconvenient to intervene a large-volume member in the gap between the toes.

The inventors further studied an embodiment which improves the above-mentioned problem. Here, I want to point out something. The above improvements only happen to people with thick toes and sweat a lot, and people with thin toes who don't sweat a lot are fine. Therefore, it is necessary to refer to the point that the original embodiment can also be preferably used.

Figure 9 is a perspective view of a toe protector according to another embodiment, Figure 10 is a right side view of the toe protector according to another embodiment. Embodiments of the drawings may be applied to the toe of the right foot.

Contents that are not specifically mentioned in other embodiments may be directly applied to other embodiments, except for content that conflicts with the content of the original embodiment or cannot be merged. Conversely, the contents of other embodiments may also be applied to the original embodiment, except for content that conflicts with the original embodiment or cannot be merged.

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

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

The wing part 210 may be a part that the user can hold when the user puts the toe protection device according to the embodiment on the toe. Accordingly, the user can conveniently hold the toe protector, wear it on the toe or take it out.

At least two holes may be perforated in the enclosure 220 and the wing portion 210 to allow sweat from the toes to 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. The straight portion 230 may be understood as including irregularities of a shape corresponding to the lifting and flying of each joint of the toe in an engineering and industrial sense, rather than referring to a straight line extending in one direction in a general sense.

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

A place marked with 'insert' in the arrow in FIG. 10 indicates an open hole and indicates the direction in which the toe is inserted.

11 to 16 are cross-sectional views of the toe protection device, which is a cross-sectional view cut up and down 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. It is a cross-sectional view of 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 , the portion close to the end 110 may be provided such that the thickness of the wall constituting the enclosure 220 is substantially similar or equally thin in all directions. For example, in a portion close to the opening 100 , the enclosure may be provided in the form of a circular frame.

Referring to FIG. 12 , at a location where blisters may occur due to the torsion force, the thickness of the enclosure 220 is increased to provide the raised part 250 . The raised part 250 can absorb deformation of the blister-prone portion, that is, strain, and prevent the end of the blister-prone portion from protruding by forming a cusp.

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

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

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

12 and 13, the thickness of the raised portion 250 may be provided in the thickest shape. Of course, the thickness of the raised portion in the longitudinal direction of the toe may be kept the same. This may be provided differently depending on the shape of the toe and the specific aspect of the blister formed on the toe. The example is presented in which the middle part is provided with the most convexity.

Referring to FIG. 14 , when the position of the raised part 250 is deviated, the enclosure 220 may be maintained in a shape of the same thickness again. However, since the portion having the shape of the toe in FIG. 14 has a portion extending vertically in a straight line, it may be provided in an oval shape extending vertically 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 part 210 further extends from the upper side of the enclosure 220 to the rear. The starting portion of the wing portion 210 may be provided in a curved shape to surround the upper portion of the root portion of the toe. The wing portion 210 may be further extended toward the rear. The wing portion 210 is fitted between the toes, the rotation of the toe protector can be prevented.

Referring to FIG. 16 , the wing portion 210 may be provided in a straight shape as a shape corresponding to a flat instep. The wing portion 210 may cover at least a portion of the instep as previously described, thereby preventing rotation of the toe protector.

It was confirmed that blisters did not occur when walking was continued while wearing the toe protection device of all the above examples.

When the toe protection device of the Examples of all the above examples was worn in a state in which blisters occurred on the toes, it was confirmed that the stimulation applied to the blisters disappeared or weakened, so that the pain caused by the blisters disappeared and it was possible to walk comfortably. However, in this case, it was confirmed that the blister 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 enlarged. Even in this case, there was no difficulty in walking because the pain caused by the blisters disappeared. In addition, due to the fact that the blister does not grow, it was possible to obtain the effect that the blister is quickly removed.

According to the present invention, it is possible to conveniently prevent blisters on the toes caused by a lot of walking. In addition, since it can be conveniently manufactured at a low cost, its use is highly expected.
