Description

  The present invention relates to a hallux valgus supporter that is attached to a foot for the purpose of preventing or correcting hallux valgus.

  Various types of hallux valgus supporters to be worn on the feet for the purpose of preventing or correcting hallux valgus have been proposed so far (for example, Patent Documents 1 to 3). This type of hallux valgus supporter is generally provided with a thumb insertion part for inserting the thumb of the toe and a toe attachment part to be attached to the toe. In many cases, the side surface opposite to the side on which the little finger is located is pulled toward the toe mounting portion side (rear side). For this reason, the tip portion of the thumb inserted into the thumb insertion portion is likely to be pressed by the pull-up, and the user may feel uncomfortable or uncomfortable.

  In view of such a situation, a conventional hallux valgus supporter is provided with a hole (hereinafter sometimes referred to as a “pressing force relief hole”) at the tip of the thumb insertion portion, and the above-mentioned pusher. Some have been made to be able to relieve pressure (see, for example, FIG. 1 of Patent Document 1). However, in this case, the big toe of the big toe protrudes from the pressing force relief hole, and the pressing force is locally applied to the outer peripheral portion of the thumb from the position along the peripheral edge of the pressing force relief hole in the thumb insertion portion. There is a risk that uncomfortable feeling or uncomfortable feeling may be caused. Sometimes, the nails of the thumb are strongly pinched from both sides, and pain may be felt.

  In this regard, by providing a pressing force relief hole on the top side of the thumb insertion part (the part that covers the nail), or by providing a small pressing force relief hole, it is difficult for the toe to protrude from the pressing force relief hole. There is also a support for hallux valgus that has been devised. However, since the thumb insertion part is usually formed of a stretchable fabric, even if the above-described device is applied, it is possible to completely prevent the toe from protruding from the pressing force relief hole. I can't. On the contrary, when the above-mentioned device is applied, if the toe of the toe gets into the pressure relief hole, the discomfort and discomfort that the user learns will increase as the above device is applied. , Would be counterproductive.

JP 2005-152218 A JP 2007-330743 A JP 2011-019560 A

  The present invention has been made in order to solve the above-described problems. Even if a pressing force relief hole is not particularly provided in the thumb insertion portion, the pressing force applied to the tip portion of the thumb due to pulling up of the thumb insertion portion or the like is provided. It is an object of the present invention to provide a hallux valgus supporter that can relieve pressure and can reduce discomfort and discomfort caused to the user.

The above issues
A thumb insertion part for inserting a big toe,
With a foot tip mounting part for mounting on the foot tip,
It is a support for hallux valgus that is made of stretch fabric.
Thumb insertion part
A planar portion α that covers one side of the outer periphery of the toe;
A planar portion β covering the other side of the outer periphery of the toe;
A planar portion γ continuously provided from the edge of the planar portion β on the fingertip side and folded in a state of being overlapped with the inner surface side of the planar portion α,
An edge α ₁ on one side in the width direction of the planar part α, an edge β ₁ on one side in the width direction of the planar part β, and an edge γ ₁ on one side in the width direction of the planar part γ are mutually connected. It is assumed to be a sewing part A that is overlapped and sewn,
An edge α ₂ on the other side in the width direction of the planar part α, an edge β ₂ on the other side in the width direction of the planar part β, and an edge γ ₂ on the other side in the width direction of the planar part γ are mutually connected. On the other hand, it is a sewing part B that is overlapped and sewn,
By providing a support for a hallux valgus characterized in that the fingertip side edge of the planar portion α and the fingertip side edge of the planar portion β are non-sewn portions that are not sewn together. Solved.

  The hallux valgus supporter according to the present invention inserts the planar portion γ continuously provided from the fingertip side edge (front edge portion) of the planar portion β into the inner surface side (thumb insertion portion) of the planar portion α. It is structured so as to be folded back so as to overlap the thumb-contacting side), and the thumb of the foot is inserted into the gap between the planar portion β and the planar portion γ. In addition, in the hallux valgus supporter according to the present invention, the planar portion α, the planar portion β, and the planar portion γ are sewn together at the edges on both sides in the width direction, but are not sewn at the front edge ( At the edges on both sides in the width direction of the planar portions α, β, γ, although the stretchability of the thumb insertion portion is hindered by a thread or the like for sewing the portion, the tip portion (front end portion) of the thumb insertion portion Stretchability is not hindered by thread etc.) Therefore, when the thumb insertion portion is pulled rearward, the planar portion γ that overlaps the inner surface side of the planar portion α is displaced so as to be pulled out to the front side, and the pressing force due to the pulling is released. Be able to. Further, the tip of the thumb insertion portion is not sewn, and the front edge of the planar portion α and the front edge of the planar portion β are separated, but the planar portion γ Therefore, even if the thumb insertion part is pulled backward strongly, the separated part does not open its mouth (a state where a hole is opened). The thumb is not sticking out.

  In the hallux valgus supporter according to the present invention, the planar portion α and the planar portion β of the thumb insertion portion have a shape that becomes narrower toward the fingertip side (a substantially trapezoidal shape with a narrower front edge side and a wider rear edge side). ) Is also preferable.

  As a result, when the thumb insertion part is tapered and the thumb insertion part is pulled backward, the pressing force applied from the thumb insertion part to the fingertip of the thumb is easily dispersed, and the user feels uncomfortable or uncomfortable. It becomes possible to make it harder to remember. Further, it is easy to hold the tip of the big toe at the tapered portion of the thumb insertion portion, and even when the thumb insertion portion is strongly pulled backward, the planar portion α and the planar portion γ It is also possible to make it difficult for the thumb to enter the gap.

In the hallux valgus supporter according to the present invention,
The foot mounting part
A planar portion δ covering the upper,
While covering the range from the sole to the back of the ankle, a planar portion ε provided with a heel opening for exposing the heel,
It shall consist of one piece of fabric having
While the planar portion δ has the stitched portion D,
It is also preferable that the planar portion ε does not have a stitched portion.

  This makes it possible to reduce the manufacturing cost of the hallux valgus supporter by reducing the number of stitches as well as forming the entire hallux valgus supporter including the thumb insertion part from one piece of fabric (elastic fabric). become. In addition, the portion of the planar portion ε that covers the rear surface of the ankle (hereinafter sometimes referred to as “ankle rear surface covering portion”) is a portion that easily hits the rear surface of the ankle. This makes it possible to improve the comfort of the hallux valgus supporter.

  However, in this case, the ankle rear surface covering portion in the planar portion ε cannot be cut three-dimensionally, and the ankle rear surface covering portion is hardly adhered to the user's ankle rear surface (the upper edge side of the ankle rear surface covering portion is the ankle rear surface). It tends to be in a state of being lifted from). For this reason, in the hallux valgus prevention supporter according to the present invention, when the surface portion ε is not provided with a stitched portion, the edge portion of the surface portion ε with the heel opening portion is located inside the heel opening portion. It is preferable to provide a protruding convex portion or a concave portion recessed on the opposite side.

  Thereby, it becomes possible to make it difficult for the upper edge side of the ankle rear surface covering portion in the planar portion ε to lift from the ankle rear surface. This is because the upper edge side of the ankle rear surface covering part is lifted from the rear surface of the ankle, which is mainly due to the difference in expansion and contraction between the upper edge side and the lower edge side of the ankle rear surface covering part. As described above, by providing a convex part or a concave part at the boundary edge of the planar part ε with the heel opening part, the perimeter of the heel opening part is lengthened and the ankle rear surface covering part is This is because the difference between the expansion and contraction on the edge side and the expansion and contraction on the lower edge side can be reduced.

  As described above, according to the present invention, the pressing force applied to the tip of the thumb due to the pulling-up of the thumb insertion portion can be released without providing a pressing force relief hole in the thumb insertion portion. It is possible to provide a hallux valgus supporter that can reduce discomfort and discomfort that occurs to the elderly.

  The preferred embodiment of the hallux valgus supporter according to the present invention will be described more specifically with reference to the drawings. FIG. 1 is a view showing a state in which the supporter 10 for hallux valgus according to the present invention is mounted on the toe as viewed from the thumb side. FIG. 2 is a view showing a state in which the hallux valgus supporter 10 according to the present invention is mounted on the toe as viewed from the little finger side. FIG. 3 is an enlarged cross-sectional view showing the periphery of the thumb insertion portion 11 in a state where the big toe is inserted. FIG. 4 is a view showing a state in which the hallux valgus supporter 10 according to the present invention is viewed from the upper side (back side). FIG. 5 is a view showing a state in which the hallux valgus supporter 10 according to the present invention is viewed from the lower side (the sole side). FIG. 6 is a development view of the hallux valgus supporter 10 according to the present invention. In FIGS. 1, 2, 4, 5, and 6, the outer surface of the hallux valgus supporter 10 (the surface facing outward when mounted) is shown by dark (fine) hatching, and the inner surface ( The surface that comes into contact with the toes when worn is shown with thin (large eyes) shaded hatching.

1. Outline of Hallux Vest Supporter 10 As shown in FIGS. 1 and 2, a hallux valgus supporter 10 according to the present invention includes a thumb insertion portion 11 for inserting a thumb, and a foot tip mounting portion 12 for mounting on a foot tip. It is intended to be used by putting on (wearing) the toes. The hallux valgus supporter 10 is generally formed of a stretchable fabric, and the side surface near the base of the thumb insertion portion 11 (the side surface opposite to the side where the little finger is located) is connected to the toe mounting portion 12. By pulling to the side (rear) and preventing the tip of the thumb from facing the little finger side, hallux valgus is prevented or corrected.

  Further, in the external sales supporter 10 of the present embodiment, by giving anisotropy to the stretchability of the stretchable fabric forming the supporter 10, a force that twists in the direction of the arrow 20 in FIG. 1 is generated. The torsional force also makes it difficult for the tip of the thumb to face the little finger. Specifically, the hallux valgus supporter 10 of the present embodiment is formed by folding a predetermined portion of one stretchable fabric shown in FIG. 6 and stitching the predetermined portion as described later. The above-mentioned torsional force is made easier by extending the stretch fabric in the direction connecting the lower right side of the drawing and the upper left side of the drawing than in the direction connecting the upper right side of the drawing and the lower left side of the drawing. Is to occur.

  The hallux valgus supporter 10 according to the present invention can be mounted on either the left foot or the right foot. That is, the hallux valgus supporter according to the present invention can be prepared for the left foot and for the right foot. The support for the hallux valgus for the left foot and the support for the hallux valgus for the right foot are usually substantially symmetrical. Therefore, in the following description, only the support for the hallux valgus for the left foot will be described, and the description for the support for the hallux valgus for the right foot will be omitted.

2. Thumb Insertion Unit As shown in FIG. 3, the thumb insertion unit 11 includes a planar portion α that covers one side of the outer periphery of the toe (the side that covers the thumb nail in the hallux valgus supporter 10 of the present embodiment), and the foot A surface portion β that covers the other side of the outer peripheral portion of the thumb (side that covers the belly of the thumb in the hallux valgus supporter 10 of the present embodiment) and a fingertip side edge of the surface portion β are provided continuously. And a planar portion γ that is folded back on the inner surface side of the planar portion α. The big toe is inserted into the gap between the inner surface (upper surface) of the planar portion β and the inner surface (lower surface) of the planar portion γ. The side surface on the little finger side of the root portion of the thumb insertion portion 11 has a cut-out shape as shown in the notch portion 11a in FIGS. 4 and 5, and the side far from the little finger in the thumb insertion portion 11 is strongly pulled backward. It is easy.

One side in the width direction of the planar portion α (in the hallux valgus supporter 10 of this embodiment, the side closer to the little finger when worn on the toes. Hereinafter, “one side in the width direction of the planar portion β and the planar portion γ. The same applies to the edge portion α ₁ (FIG. 6), the edge portion β ₁ (FIG. 6) on one side in the width direction of the planar portion β, and the edge portion γ on the one side in the width direction of the planar portion γ. ₁ (FIG. 6) is a sewn portion A (FIGS. 2, 4, and 5) that is overlapped and sewn together. Further, the other side in the width direction of the planar portion α (in the hallux valgus supporter 10 of the present embodiment, the side farther from the little finger when worn on the toe. Hereinafter, the “width direction of the planar portion β and the planar portion γ” The same applies to “other side”.) Edge α ₂ (FIG. 6), edge β ₂ (FIG. 6) on the other side in the width direction of the planar part β, and edge on the other side in the width direction of the sheet part γ The part γ ₂ (FIG. 6) is a sewn part B sewn together. In the hallux valgus supporter 10 of this embodiment, as shown in FIG. 4, the sewing line of the sewing part A appears along the right edge of the thumb insertion part 11, and the sewing line of the sewing part B is the thumb. It appears along the left edge of the insertion portion 11.

  On the other hand, the fingertip side edge of the planar portion α and the fingertip side edge of the planar portion β are non-sewn portions X (FIGS. 1 to 5) that are not sewn together. For this reason, when the support member 11 for hallux valgus is attached to the foot tip and the thumb insertion portion 11 is pulled rearward, the planar portion γ that overlaps the inner surface side of the planar portion α is pulled out to the front side. It is possible to release the pressing force resulting from the displacement. Therefore, it is possible to reduce the discomfort and discomfort that occur to the user. By the way, as already described, since the distal end portion of the thumb insertion portion 11 is the stitched portion X, the front edge portion of the planar portion α and the front edge portion of the planar portion β are in a separated state. It is. However, since the separated portion is closed by the planar portion γ, even if the thumb insertion portion 11 is strongly pulled backward, the separated portion is in a state where the mouth is opened (a hole is opened). The toe does not protrude from the non-sewn portion X.

  The shape of the planar portion α and the planar portion β forming the thumb insertion portion 11 is not particularly limited as long as the shape of the thumb portion can be held. In the hallux valgus supporter 10 according to the present embodiment, the planar portion α and the planar portion β are shaped so that the width becomes narrower toward the fingertip side (the leading edge side is narrow and the trailing edge side as shown in FIGS. 4 and 5). Is a broad trapezoidal shape). For this reason, when the thumb insertion part 11 is pulled back, the pressing force applied to the fingertip of the thumb from the thumb insertion part 11 is easily dispersed. Further, even when the thumb insertion portion 11 is strongly pulled backward by making it easier to hold the tip of the toe with the tapered portion of the thumb insertion portion 11, the planar portion α and the planar portion γ. It is also possible to make it difficult for the thumb to enter the gap.

Further, the shape of the planar portion γ is not particularly limited, but is usually a shape that follows the planar portion α. The front-rear length L ₁ (FIG. 4) of the overlapping portion of the planar portion α and the planar portion γ is not particularly limited. However, too short a longitudinal length L ₁ of the overlapping portion, when the thumb insertion portion 11 is pulled strongly to the rear, the portion dough at the tip of the finger insertion portion 11 is separated (unsewn portion X) There is a risk of opening the mouth. Therefore, longitudinal length L ₁ of the overlapping portion of the planar portion α and planar portion γ is preferably When higher 5 mm, more preferably when a 10mm or more, further preferable to set 15mm or more. The upper limit of the longitudinal length L ₁ of the overlapping portion of the planar portion α and planar portion γ is not particularly limited, considering the length, etc. of the big toe, is up to at most about 50 mm. In hallux valgus supporter 10 of the present embodiment, longitudinal length L ₁ of the overlapping portion of the planar portion α and planar portion γ is set to about 20 mm.

3. Foot Toe Mounting Part The foot toe mounting part 12 has a planar part δ and a planar part ε as shown in FIGS. The planar portion δ is a portion that covers the instep of the foot. In the hallux valgus supporter 10 of the present embodiment, the planar portion δ ₁ that covers the left side of the upper and the planar portion δ ₂ that covers the right side of the upper It is formed by joining together. On the other hand, the planar portion ε is a portion that covers a range from the sole to the rear surface of the ankle, and in the hallux valgus supporter 10 of the present embodiment, the planar portion ε ₁ that covers the sole and the belt-shaped portion that covers the rear surface of the ankle. The planar portion ε ₂ (corresponding to the “ankle rear surface covering portion” described above) is included.

Further, the planar portion epsilon, between the planar portion epsilon ₁ and planar portion epsilon _2, is provided with a heel opening 12a for exposing the heel. Furthermore, a four-finger opening 12b for exposing the four fingers from the index finger to the little finger is provided on the front left side of the foot mounting part 12. Furthermore, a foot tip insertion opening 12 c for inserting a foot tip into the inside of the hallux valgus supporter 10 is provided on the upper rear side of the foot tip mounting portion 12.

Further, the hallux valgus supporter 10 of the present embodiment has a planar portion α, a planar portion β, and a planar portion α that form the thumb insertion portion 11 in addition to the planar portion δ and the planar portion ε that form the foot-tip mounting portion 12. The planar portion γ is formed of one stretchable fabric shown in FIG. 6, and the portions shown in FIGS. 4 and 5 are formed by folding back predetermined portions of the stretchable fabric and stitching each portion. The planar portion δ is sewn at the stitching portion D, but is not sewn at the planar portion ε. Of the planar portion ε, the planar portion ε ₁ is a portion on which the weight of the user is applied, and the planar portion ε ₂ is a portion that easily hits the rear surface of the ankle. by separate component epsilon ₁ and planar portion epsilon ₂ is not provided sutures, it is possible to improve the comfort of the hallux valgus supporter. A specific method for forming the hallux valgus supporter 10 from a single stretchable fabric will be described in detail in “4. Method for manufacturing a hallux valgus support” to be described later.

However, in the case without the suture portion into the planar portion epsilon (especially planar portion epsilon ₂₎ is planar portion epsilon (particularly planar portion epsilon ₂₎ will not be able to draping, the planar portion epsilon ₂ (The upper edge side of the planar portion ε ₂ (the upper edge when worn on the foot tip, the lower edge of the paper in FIGS. 4 to 6). ) Is likely to rise from the back of the ankle). In this respect, in the hallux valgus prevention supporter 10 of this embodiment, as shown in FIGS. 4 to 6, a protrusion protruding inward of the heel opening at the boundary edge with the heel opening 12 a in the planar portion ε. By providing the shape portion 12c ₁ and increasing the peripheral length of the heel opening 12c ₁ and suppressing the difference between the expansion state on the upper edge side and the expansion state on the lower edge side of the surface portion ε ₂ , the surface portion so as to prevent the lifting of the ε _2.

Convex portion 12c _1, if the boundary edges of the heel opening 12a in the planar portion epsilon, where providing it is not particularly limited. However, rather than providing the convex portion 12c ₁ to the front section (section remote from the planar portion epsilon ₂₎ of the boundary edge, closer to the side section (planar section epsilon ₂ after the terminal edge It was confirmed that the raised portion of the planar portion ε ₂ is not small when the convex portion 12 c ₁ is provided in the section). Therefore, even in the hallux valgus supporter 10 of the present embodiment is provided with the convex portion 12c ₁ to the side sections after the border edge between the heel opening 12a in the planar portion epsilon. In the hallux valgus supporter 10 of this embodiment, the convex portion 12c ₁ is provided at only one place, but may be provided at a plurality of places. Further, the convex portion 12c ₁ may be replaced by a concave portion recessed on the outside of the heel opening.

4). Next, a method for manufacturing the hallux valgus supporter 10 will be described. The hallux valgus supporter 10 of this embodiment is manufactured through the following steps 1 to 6.

[Step 1]
First, the stretchable fabric cut into the shape of FIG. 6 is formed by placing the planar portion γ so that the edge β ₁ and the edge γ ₁ overlap and the edge β ₂ and the edge γ ₂ overlap. Fold back to the back side (inner surface side, back side of the paper in FIG. 6) of the shape portion β.
[Step 2]
The stretchable fabric that has finished the process 1 is arranged such that the edge α ₁ and the edge β ₁ overlap and the edge α ₂ and the edge β ₂ overlap, and the surface α is the front of the surface β. Fold back to the side (outer side, front side in FIG. 6). At this time, it overlaps an edge alpha ₁ and the edge beta ₁ and the edge gamma _1, has an edge alpha ₂ and the edge beta ₂ and the edge gamma ₂ that the overlapping state.
[Step 3]
The stretchable fabric that has finished Step 2 is stitched at a portion where the edge α ₁ , the edge β _1, and the edge γ ₁ overlap to form a stitched portion A, and the edge α ₂ and the edge β ₂ sutured at the edge gamma ₁₂ and is overlapped portion and stapling portion a. Thereby, the thumb insertion part 11 is formed. At this time, the thumb insertion part 11 is in a state where the front and the back are turned over. The reason why the seam and the back are turned upside down is to prevent the seam allowance of the sewn part A and the seam allowance of the sewn part B from appearing on the outer surface of the hallux valgus supporter 10.

[Step 4]
The stretchable fabric having been subjected to the step 3, to overlap and the edge [delta] ₃ and the edge [delta] _4, folding the stretchable fabric into a tubular shape. This cylindrical folding is performed so that the front side of the stretchable fabric is the inside and the back side of the stretchable fabric is the outside.
[Step 5]
The stretchable fabric that has become cylindrical after the process 4 is stitched at a portion where the edge δ ₃ and the edge δ ₄ overlap to form a stitched portion B. Thereby, the foot tip mounting portion 12 is formed, and the foot tip mounting portion 12 at this time is in a state where the front and back are turned over. The reason why the seam and the back are turned upside down is to prevent the seam allowance of the stitched portion D from appearing on the outer surface of the hallux valgus supporter 10.

[Step 6]
The front and back of the toe mounting portion 12 of the stretchable fabric (valgus valgus supporter 10) that has finished Step 6 are turned over, and the front and back of the thumb insertion portion 11 are also turned over. Thereby, the supporter 10 for hallux valgus shown in FIG.4 and FIG.5 is obtained. At this time, the seam allowance of the suture part A, the seam allowance of the seam part B, and the seam allowance of the seam part D are hidden on the inner surface side of the tubular stretchable fabric (valgus valgus supporter 10) and on the outer surface side. It does not appear.

  When the above manufacturing method is adopted, the hallux valgus having a relatively complicated form as shown in FIGS. 4 and 5 is obtained by performing the suturing only at the three portions of the stitching portion A, the stitching portion B, and the stitching portion C. Supporter 10 can be manufactured. Therefore, the manufacturing cost of the hallux valgus supporter 10 can be reduced.

  By the way, in the said process 1-6, although each part was stitched in the state where the front and back of the hallux valgus supporter 10 turned over, if the seam allowance may appear on the outer surface side of the hallux valgus supporter 10, You may reverse the direction which folds each planar part in each process. In this case, the above step 6 need not be performed. Moreover, in the said process 1-6, after forming the thumb insertion part 11 (after performing process 1-3), the foot tip insertion part 12 was formed (process 4, 5), but this order is reverse. It may be. That is, the thumb insertion portion 11 may be formed after the foot tip insertion portion 12 is formed.
