Description

本発明は、巻き爪が生じている指、特に、親指に装着して巻き爪を矯正する巻き爪矯正具に関するものである。   The present invention relates to an incurvated nail corrector that is attached to a finger, particularly a thumb, in which the ingrown nail is generated to correct the ingrown nail.

巻き爪矯正具としては、従来から種々の形状、構造を有するものが開発され、例えば、特許文献１に記載されているように、ゴム弾性を有する伸縮矯正具、又は、弾性金属板の長さ方向の両側端に巻き爪の両側端に引っ掛けるフック形状の係止片を取付けてなる巻き爪矯正具や、特許文献２に記載されているように形状記憶合金又は形状記憶樹脂よりなり、爪の甲部に貼着して加温することにより、巻き爪を矯正する方向に屈曲させるように構成した矯正具、さらには、特許文献３に記載されているように、弾性を有する細長い薄板の先端部を下方に折り返して巻き爪の先端部に引っ掛ける係止片部に形成してなり、爪の上面に粘着テープによって固定して係止片部を巻き爪の先端部に係止させた状態に保持するように構成した矯正具などが開発されている。   As curly nail correction tools, those having various shapes and structures have been developed. For example, as described in Patent Document 1, the length of a stretchable correction tool having rubber elasticity or an elastic metal plate is used. It consists of a shape nail corrector formed by attaching hook-shaped locking pieces that are hooked to both ends of the direction nail on both sides in the direction, or a shape memory alloy or shape memory resin as described in Patent Document 2, A corrector configured to bend in the direction of correcting the wound nail by sticking to the upper and heating, and further, as described in Patent Document 3, the tip of an elongated thin plate having elasticity It is formed in the locking piece part that folds down the part and hooks on the tip part of the winding claw, and is fixed to the upper surface of the claw with adhesive tape, and the locking piece part is locked to the tip part of the winding claw Corrective tools configured to hold It has been issued.

しかしながら、特許文献１に記載された構造の巻き爪矯正具においては、ゴム弾性を有する伸縮矯正具は、爪の幅方向にその弾性収縮力を作用させるように構成しているため、巻き爪の両側端に係止させているこの伸縮矯正具の両側端の係止片に対しては、その弾性収縮力が巻き爪の両側端間を狭めようとする作用力として大きく働く一方、巻き爪を引き起こす方向、即ち、矯正しようとする方向への作用力が小さくなり、矯正力として有効に作用させることができないといった問題点がある。   However, in the curly nail corrector having the structure described in Patent Document 1, the elastic corrector having rubber elasticity is configured to exert its elastic contraction force in the width direction of the nail. While the elastic contraction force acts on the locking pieces on both ends of this stretchable orthodontic tool that is locked on both ends, it acts as an action force to narrow the gap between both ends of the winding nail. There is a problem in that the acting force in the direction to be caused, that is, the direction to be corrected becomes small and cannot be effectively applied as the correcting force.

一方、特許文献２に記載されているような形状記憶合金又は形状記憶樹脂よりなる巻き爪矯正具によれば、この矯正具を爪の甲部に貼着する接着剤の接着力が弱いと矯正具が爪の甲部から簡単に剥離して矯正ができなくなり、接着力が強いと剥離が困難となる問題点が生じ、その上、巻き爪を矯正するには、この矯正具をドライヤや温湯で加温する必要があって長時間、連続的に矯正力を発揮させることが困難であるばかりでなく、加温を止めると、元の形状に復帰して矯正が行えなくなるといった問題点がある。   On the other hand, according to the wound nail corrector made of a shape memory alloy or shape memory resin as described in Patent Document 2, it is corrected if the adhesive force of the adhesive that sticks the corrector to the back of the nail is weak. The tool can be easily peeled off from the back of the nail and cannot be corrected. If the adhesive strength is strong, the peeling becomes difficult. It is not only difficult to exert the corrective power continuously for a long time, but also when the heating is stopped, there is a problem that the original shape is restored and correction cannot be performed. .

また、特許文献３に記載されているような巻き爪矯正具によれば、弾性を有する細長い薄板の先端部を下方に折り返して巻き爪の先端部に引っ掛ける係止片部に形成してなるものであるから、使用に際して、この係止片部を巻き爪の一側端縁部又は他側端縁部における先端部に簡単に引っ掛けることができて巻き爪に対する装着が容易に行える利点を有するが、係止片部を巻き爪の先端部に引っ掛けた状態にしてこの矯正具を粘着テープによって爪の上面に固定しても、係止片部に巻き爪を引き起こそうとする充分な矯正力を生じさせることが困難であり、また、この矯正部を巻き爪の先端を支点として積極的に巻き爪の上面に向かって弾性変形させ、その弾性力によって係止片部に巻き爪を引き起こそうとする矯正力を生じさせようとしても、支点が巻き爪の先端であるため、係止片部を巻き爪の先端から前方に向かって離脱させる方向に作用して巻き爪を矯正する方向には殆ど作用せず、効果的な矯正力を得ることができないといった問題点があった。   Moreover, according to the ingrown nail correction tool as described in Patent Document 3, the tip of the elastic thin thin plate is formed into a locking piece that is folded downward and hooked to the end of the ingrown nail. Therefore, in use, there is an advantage that this locking piece portion can be easily hooked to the tip end portion of one side edge portion or the other side edge portion of the winding nail and can be easily attached to the winding nail. Even if the locking piece is hooked on the tip of the wound nail, even if this corrector is fixed to the upper surface of the nail with adhesive tape, sufficient correction force to cause the locking nail to cause the wound nail In addition, the correction part is positively elastically deformed toward the upper surface of the winding nail with the tip of the winding nail as a fulcrum, and the elastic nail causes the winding nail to the locking piece part. Trying to generate the corrective power Since the fulcrum is the tip of the wound nail, it acts in a direction to detach the locking piece from the tip of the wound nail toward the front, and hardly acts in the direction to correct the wound nail, and effective correction force There was a problem that could not be obtained.

本発明はこのような問題点に鑑みてなされたもので、その目的とするところは、巻き爪に対する装着が簡単に行えるばかりでなく、テコの原理を利用して巻き爪に対し、長時間に亘って有効で且つ安定した矯正力を発揮して巻き爪の矯正を行うことができる巻き爪矯正具を提供するにある。   The present invention has been made in view of such problems, and the object of the present invention is not only to be easily attached to the winding nail, but also to the winding nail for a long time using the lever principle. An object of the present invention is to provide an incurvated nail correction tool which can correct an incurvated nail while exhibiting an effective and stable correction force.

上記目的を達成するために本発明の巻き爪矯正具は、請求項１に記載したように、硬質の弾性板片からなり、先端に巻き爪に引っ掛けるフック形状の係止片部を形成している巻爪矯正具本体の基端に、この巻き爪矯正具本体に対して斜め上方に５度〜２５度の角度でもって傾斜しているレバー片を一体に設けていると共に、巻き爪矯正具本体とレバー片との屈折連設部を支点部に形成してなり、レバー片を粘着テープ等の固定用テープによって爪上に固定するように構成している。   In order to achieve the above object, the ingrown nail correction tool according to the present invention comprises a hard elastic plate piece as described in claim 1 and has a hook-shaped engaging piece portion hooked on the ingrown nail at the tip. A lever piece that is inclined at an angle of 5 to 25 degrees obliquely upward with respect to the curly nail corrector body is integrally provided at the proximal end of the curly nail corrector body, and the curly nail corrector A refracting continuous portion between the main body and the lever piece is formed at the fulcrum portion, and the lever piece is fixed on the claw with a fixing tape such as an adhesive tape.

このように構成した巻き爪矯正具において、請求項２に係る発明は、巻き爪矯正具本体の両側端面間の横幅を長さ方向の中間部から先端部に向かって徐々に幅狭くなるように形成していると共に、少なくとも巻き爪の患部側に位置する側部の側端面を凸円弧状に湾曲した湾曲側端面に形成してその側部を患部保護片部に形成していることを特徴とする。   In the ingrown nail corrector configured as described above, the invention according to claim 2 is such that the lateral width between the both end surfaces of the ingrown nail corrector main body is gradually narrowed from the intermediate portion in the length direction toward the tip end portion. And at least the side end surface of the side located on the affected part side of the wound nail is formed as a curved side end surface curved in a convex arc shape, and the side part is formed on the affected part protection piece part. And

さらに、請求項３に係る発明は、上記巻き爪矯正具本体を支点部から先端部に向かって緩やかな凸円弧状に湾曲させていることを特徴とする。   Furthermore, the invention according to claim 3 is characterized in that the curled nail correction tool body is curved in a gentle convex arc shape from the fulcrum portion toward the tip portion.

また、請求項４に係る発明は、上記レバー片に上下面間に亘って貫通した通気孔を設けていることを特徴とする。なお、巻き爪矯正具本体は、金属薄板製であってもよいが、好ましくは、腰の強い弾性を有する硬質合成樹脂、特に、請求項５に記載したようにポリカーボネート樹脂よりなることが望ましい。   The invention according to claim 4 is characterized in that the lever piece is provided with a vent hole penetrating between the upper and lower surfaces. The curly nail corrector main body may be made of a thin metal plate, but is preferably made of a hard synthetic resin having strong elasticity, in particular, a polycarbonate resin as described in claim 5.

請求項１に係る発明によれば、硬質の弾性板片からなる巻き爪矯正具本体の先端に巻き爪に引っ掛けるフック形状の係止片部を形成しているので、指先から突出する巻き爪の先端にこの係止片部を容易に係止させることができるのは勿論、巻爪矯正具本体の基端に、この巻き爪矯正具本体に対して斜め上方に傾斜しているレバー片を一体に設けていると共に、巻き爪矯正具本体とこのレバー片との屈折連設部を支点部に形成しているので、巻き爪矯正具本体の先端係止片部を巻き爪の先端に係止させて支点部を爪の上面に受止させると、レバー片がこの支点部から後方に向かって斜め上方に傾斜した状態となり、従って、レバー片を粘着テープ等の固定用テープによって爪の上面に押し付けるようにして固定すると、レバー片が支点部を中心にして下方に向かって弾性的に押圧されて、巻き爪矯正具本体がテコの作用によりその先端側を起立させる方向に作動し、巻き爪の先端部に係止している係止片部を積極的に上方に持ち上げようとする矯正力が発生して巻き爪を効果的に矯正することができる。   According to the first aspect of the present invention, since the hook-shaped locking piece portion hooked on the winding nail is formed at the tip of the winding nail correction tool body made of a hard elastic plate piece, the winding nail protruding from the fingertip is formed. Of course, the locking piece can be easily locked to the tip, and a lever piece that is inclined obliquely upward with respect to the curl nail corrector body is integrated with the base end of the curl nail corrector body. Since the refracting portion of the curl nail corrector main body and this lever piece is formed at the fulcrum part, the tip locking piece of the curl nail corrector main body is locked to the tip of the curl nail. When the fulcrum part is received on the upper surface of the nail, the lever piece is inclined obliquely upward from the fulcrum part to the rear, and therefore the lever piece is fixed to the upper surface of the nail by a fixing tape such as an adhesive tape. When fixed by pressing, the lever piece is centered on the fulcrum Then, the locking piece portion that is elastically pressed downward and operates in a direction in which the curly nail correction tool main body rises its tip side by the action of the lever and is locked to the leading end portion of the curling nail. A correction force that actively lifts upward is generated, and the wound nail can be corrected effectively.

さらに、このようにテコの作用によって係止片部を巻き爪の矯正方向に作用させた状態にして固定用テープによって固定するので、巻き爪矯正力を長時間に亘って安定的に且つ有効に発揮させて巻き爪を矯正することができる。その上、巻き爪矯正具本体に対して斜め上方に傾斜するレバー片の傾斜角度を５度以下にした場合には、レバー片を下方に押圧した時に該レバー片が直ちに爪上に当接して巻き爪に係止している係止片部にテコの作用による充分な矯正力を発揮させることができず、また、上記傾斜角度を２５度以上にすると、レバー片を爪の上面まで押し下げた状態にして固定テープにより巻き爪矯正具を固定することによって係止片部に生じる、巻き爪を弾性的に引き上げようとする矯正力が大きくなりすぎて痛みを生じさせる虞れがあると共にレバー片の弾性復元力が大きくなって固定テープによる安定した巻き爪の固定が困難となるが、本発明によれば、上記巻き爪矯正具本体に対して斜め上方に傾斜するレバー片の傾斜角度を５度〜25度に設定しているので、テコの作用による安定した巻き爪矯正力を長時間に亘って発生させて巻き爪を矯正することができる。   In addition, since the locking piece is made to act in the correction direction of the ingrown nail by the action of the lever as described above and fixed by the fixing tape, the incurvated nail correction force is stably and effectively applied over a long period of time. It can be used to correct wound nails. In addition, when the inclination angle of the lever piece inclined obliquely upward with respect to the curly nail correction tool body is set to 5 degrees or less, the lever piece immediately contacts the nail when the lever piece is pressed downward. The locking piece portion locked to the winding nail cannot exert a sufficient correction force due to the action of the lever, and when the inclination angle is 25 degrees or more, the lever piece is pushed down to the upper surface of the nail. The lever piece is likely to cause pain due to an excessively large correction force to elastically pull up the wound nail generated in the locking piece by fixing the curl nail correction tool with the fixing tape in the state However, according to the present invention, the inclination angle of the lever piece that is inclined obliquely upward with respect to the curl nail corrector main body is set to 5 according to the present invention. Set to 25 degrees Runode, it is possible to correct the stable pincer nail correction force a long time to generate over the by pincer nail due to the action of leverage.

請求項２に係る発明によれば、巻き爪矯正具本体は、その両側端面間の横幅を長さ方向の中間部から先端部に向かって徐々に幅狭くなるように形成していると共に、少なくとも巻き爪の患部側に位置する側部の側端面を外側方に向かって凸円弧状に湾曲した湾曲側端面に形成してその側部を患部保護片部に形成しているので、巻き爪の食い込み等によって生じている炎症部分をこの患部保護片部によって被覆してズボンの裾などが患部に当たって強い痛みを与えるのを防止することができる。   According to the invention of claim 2, the curly nail corrector main body is formed such that the lateral width between both side end surfaces is gradually narrowed from the intermediate portion in the length direction toward the tip portion, and at least Since the side end surface of the side located on the affected part side of the wound nail is formed on the curved side end surface curved in a convex arc shape toward the outer side, and that side part is formed on the affected part protection piece, The inflamed part caused by biting or the like can be covered with the affected part protection piece to prevent the bottom of the pants from hitting the affected part and giving strong pain.

さらに、請求項３に係る発明によれば、巻き爪矯正具本体を支点部から先端部に向かって緩やかな凸円弧状に湾曲させているので、巻き爪先端部に対する係止片部の係止が巻き爪矯正具本体に邪魔されることなく円滑且つ確実に行うことができると共に、上記患部保護片部上を介して指に固定テープを巻着した場合に、患部保護片部と患部との間に空間を設けることができて、固定テープが患部に密着することなく、患部を効果的に保護することができる。   Further, according to the invention of claim 3, since the curly nail corrector main body is curved in a gentle convex arc shape from the fulcrum portion toward the tip portion, the latch piece portion is locked to the tip portion of the curl nail. Can be performed smoothly and reliably without being obstructed by the curly nail corrector body, and when the fixing tape is wound around the finger via the above-mentioned affected part protective piece part, A space can be provided between them, and the affected part can be effectively protected without the fixing tape being in close contact with the affected part.

また、請求項４に係る発明によれば、上記レバー片に通気孔を設けているので、この通気孔から通気性を有する粘着テープ等の固定テープを通じて外部に通気させて、レバー片により被覆されている爪部分における爪で呼吸している爪の付け根の柔らかい部分である爪母が蒸れるのを防止することができ、快適な着用を可能にすることができる。   According to the invention according to claim 4, since the lever piece is provided with a vent hole, the vent piece is vented to the outside through a fixing tape such as an air-permeable adhesive tape and is covered with the lever piece. The nail mother, which is the soft part of the base of the nail that is breathing with the nail in the nail part, can be prevented from being steamed, and comfortable wearing can be made possible.

上記巻き爪矯正具を腰の強い弾性を有する硬質合成樹脂、特に、請求項５に記載したようにポリカーボネート樹脂によって形成することにより、支点部を中心として下方に撓もうとするレバー片の弾性抵抗力を比較的大きくすることができ、巻き爪の先端に係止した係止片部に上記テコの作用を介して巻き爪の矯正に必要な充分な矯正力を長時間に亘って安定的に付与することができる巻き爪矯正具を提供することができる。   By forming the curly nail correction tool from a hard synthetic resin having strong elasticity, in particular, a polycarbonate resin as described in claim 5, the elastic resistance of the lever piece which is to be bent downward about the fulcrum portion The force can be made relatively large, and the corrective force necessary for correcting the ingrown nail can be stably applied over a long period of time through the action of the lever to the engaging piece portion engaged with the tip of the ingrown nail. An ingrown nail correction tool that can be applied can be provided.

本発明の具体的な実施の形態を図面について説明すると、図１、図２に示すように、巻き爪矯正具Ａは、前後方向の長さが爪Ｂの先端から付け根までの長さよりも僅かに長く形成され、且つ、基端部側の横幅が爪Ｂの１／２〜１／３の幅に形成されている巻き爪矯正具本体１と、この巻き爪矯正具本体１の先端に下方から後方に向かってフック形状に折り返し屈曲形成してなる係止片部２と、巻き爪矯正具本体１の基端部に対してこの基端から後方に向かって斜め上方に緩やかに傾斜している矩形平板状のレバー片３とからなり、巻き爪矯正具本体１の基端とレバー片３の先端との連設部を支点部４に形成している。又、上記係止片部２の下面とレバー片３の下面とが略同一水平面上に配置されるように形成されている。   A specific embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the wound nail corrector A has a length in the front-rear direction slightly smaller than the length from the tip of the nail B to the root. And a curly nail corrector main body 1 which is formed to be 1/2 to 1/3 of the width of the nail B, and the lower end of the curly nail corrector main body 1 is formed downward. From the base end portion of the nail corrector main body 1 to the rear end of the hook nail corrector body 1 and gently slanting upward and obliquely upward from the base end. The fulcrum portion 4 is formed with a continuous portion between the proximal end of the curl nail corrector main body 1 and the distal end of the lever piece 3. Further, the lower surface of the locking piece portion 2 and the lower surface of the lever piece 3 are formed so as to be disposed on substantially the same horizontal plane.

巻き爪矯正具Ａを形成している材料としては、金属薄板から形成しておいてもよいが、腰の強い弾性を有するポリカーボネート樹脂や硬質塩化ビニル樹脂等の合成樹脂、特に、ポリカーボネート樹脂より形成しておくことが望ましい。この巻き爪矯正具Ａの具体的な大きさとしては、厚みが１mm程度、巻き爪矯正具本体１の先端からレバー片３の後端（基端）までの長さが18mm、巻き爪矯正具本体１の基端部とレバー片３との横幅が10〜12mm、巻き爪矯正具本体１の長さが８mm、巻き爪矯正具本体１の先端の横幅が５mm、係止片部２の長さが４mm程度でその先端部の幅が５mm程度、巻き爪矯正具本体１の先端部下面と係止片部２の先端間の隙間が１mmに形成されているが、このような寸法に特に限定されることはない。   The material for forming the ingrown nail correction tool A may be formed from a thin metal plate, but is formed from a synthetic resin such as a polycarbonate resin or a hard vinyl chloride resin having strong elasticity, particularly a polycarbonate resin. It is desirable to keep it. The specific size of the ingrown nail corrector A is about 1 mm thick, the length from the front end of the ingrown nail corrector main body 1 to the rear end (base end) of the lever piece 3 is 18 mm, the ingrown nail corrector The width of the base end of the main body 1 and the lever piece 3 is 10 to 12 mm, the length of the curly nail corrector main body 1 is 8 mm, the width of the tip of the curly nail corrector main body 1 is 5 mm, and the length of the locking piece 2 The gap between the tip bottom surface of the curly nail corrector body 1 and the tip of the locking piece 2 is 1 mm. There is no limit.

巻き爪矯正具本体１とレバー片３との連設部に形成している上記支点部４の屈折角度、即ち、巻き爪矯正具本体１の基端から後方に延長する水平面とレバー片３とのなす角度θを５度〜25度、好ましくは、10度〜15度の緩やかな傾斜角度に形成している。換言すれば、巻き爪矯正具本体１の上面とレバー片３の上面とのなす角度を155 度〜175 度、好ましくは165 度〜170 度に形成している。   The angle of refraction of the fulcrum part 4 formed at the connecting portion between the incurvated nail corrector main body 1 and the lever piece 3, that is, the horizontal plane extending backward from the base end of the ingrown nail corrector main body 1 and the lever piece 3 Is formed at a gentle inclination angle of 5 to 25 degrees, preferably 10 to 15 degrees. In other words, the angle formed between the upper surface of the ingrown nail corrector main body 1 and the upper surface of the lever piece 3 is 155 degrees to 175 degrees, preferably 165 degrees to 170 degrees.

さらに、巻き爪矯正具本体１の両側端間の横幅を基部から先端に向かって徐々に幅狭くなるように形成し、その先端から前方に突出する細幅の部分を上述したように下方から後方に向かって折り返すように屈曲させてなる係止片部２に形成しているが、巻き爪矯正具本体１の基部から先端に至る部分の横幅を直線状に幅狭くすることなく、両側端面を外側に向かって緩やかな凸円弧状に湾曲させて、幅狭くなる部分の両側部をできるだけ外側方に突出させてあり、この凸円弧状の湾曲側部を患部保護部1a、1aに形成していると共に、巻き爪矯正具本体１は側面から見て、その基部から先端部に亘る部分を上方に向かって緩やかな凸円弧状に湾曲させている。   Further, the lateral width between both side ends of the ingrown nail corrector main body 1 is formed so as to gradually become narrower from the base toward the tip, and the narrow portion protruding forward from the tip is rearward from below as described above. Is formed on the locking piece portion 2 that is bent so as to be folded back, but the lateral end surfaces of the curled nail correction tool main body 1 from the base portion to the tip end are not narrowed linearly. Curved in a gently convex arc shape toward the outside, both side portions of the narrowed portion are projected as far as possible outward, and this convex arc-shaped curved side portion is formed in the affected part protection part 1a, 1a At the same time, when viewed from the side, the curled nail corrector main body 1 has a portion extending from the base portion to the tip portion thereof curved upward in a gentle convex arc shape.

また、巻き爪矯正具Ａを爪上に装着した際に、爪の付け根部分（爪母）を被覆するレバー片３の中央部ないしは後部に上下面間に貫通した通気孔５を設けてあり、この通気孔５によって爪母が蒸れるのを防止するようにしている。なお、通気孔５の形状としては、円形であっても十字形状であっても、或いはその他の形状であってもよい。   In addition, when the curly nail correction tool A is mounted on the nail, the vent hole 5 penetrating between the upper and lower surfaces is provided in the center part or the rear part of the lever piece 3 that covers the base part (nail mother) of the nail, This ventilation hole 5 prevents the nail mother from being steamed. The vent hole 5 may have a circular shape, a cross shape, or other shapes.

次に、このように構成した巻き爪矯正具Ａを使用して巻き爪を矯正するには、まず、巻き爪矯正具Ａを巻き爪が生じている側、例えば、親指の一側部側に生じている場合には、その爪の一側部上に配設して図３、図４に示すように、係止片部２を巻き爪の先端に引っ掛けて係止させ、支点部４を爪Ｂの上面に受止させた状態にすると共に、巻き爪が生じている爪Ｂの一側端の先端部上を巻き爪矯正具本体１の一側部側の外方に向かって凸円弧状に張り出した患部保護部1aにより被覆した状態にする。   Next, in order to correct the ingrown nail using the ingrown nail correction tool A configured as described above, first, the ingrown nail correction tool A is placed on the side where the ingrown nail is generated, for example, on one side of the thumb. If it has occurred, it is arranged on one side of the claw, and as shown in FIGS. 3 and 4, the locking piece 2 is hooked and locked to the tip of the winding claw, and the fulcrum portion 4 is The upper surface of the nail B is in a state of being received, and a convex circle is formed on the tip of the one side end of the nail B where the nail is generated toward the outer side of the one side of the wound nail corrector body 1. The state is covered with the affected part protection part 1a projecting in an arc shape.

しかるのち、巻き爪矯正具本体１の基端から支点部４を介して後方に向かって斜め上方に傾斜しているレバー片３をその傾斜角度がなくなるように弾性変形させながら押し下げて指の甲部上に押し付けると、このレバー片３の押し下げ力を力点として巻き爪矯正具本体１が上記支点部４を支点とするテコ作用により起立する方向に作動して巻き爪の先端に係止している係止片部２が引き起こされて巻き爪を弾性的に矯正する作用力が発生する。   After that, the lever piece 3 that is inclined obliquely upward from the base end of the ingrown nail correction tool body 1 to the rear via the fulcrum part 4 is pushed down while being elastically deformed so that the inclination angle disappears, and the back of the finger. When pressed onto the part, the curled nail corrector main body 1 operates in the direction of standing by the lever action with the fulcrum part 4 as a fulcrum using the pushing force of the lever piece 3 as a power point, and is locked to the tip of the curl nail. The acting locking piece 2 is caused to generate an action force that elastically corrects the wound nail.

この際、巻き爪矯正具本体１に対してレバー片３の傾斜角度を５度以下にしておくと、レバー片３を下方に押圧した時に、該レバー片３が直ちに爪Ｂ上に当接して巻き爪に係止している係止片部２にテコ作用による充分な矯正力を発揮させることができず、また、上記傾斜角度を２５度以上にすると、レバー片３を爪の上面まで押し下げるにはその間に大きな弾性抵抗力が発生して係止片部２による巻き爪を持ち上げようとする矯正力が大きくなりすぎるので、上記巻き爪矯正具本体１に対して斜め上方に傾斜するレバー片３の傾斜角度を５度〜25度、好ましくは、10〜15度に設定しておくことが望ましい。   At this time, if the inclination angle of the lever piece 3 is set to 5 degrees or less with respect to the curl nail corrector main body 1, the lever piece 3 immediately contacts the nail B when the lever piece 3 is pressed downward. The locking piece portion 2 locked to the winding nail cannot exert a sufficient correction force due to the lever action, and when the inclination angle is 25 degrees or more, the lever piece 3 is pushed down to the upper surface of the nail. In the meantime, since a large elastic resistance force is generated and the correction force for lifting the wound nail by the locking piece portion 2 becomes too large, the lever piece inclined obliquely upward with respect to the wound nail correction tool body 1 It is desirable that the inclination angle 3 is set to 5 to 25 degrees, preferably 10 to 15 degrees.

次いで、爪Ｂの上面に押し付けたレバー片３を図５、図６に示すように粘着テープ６によって指の甲部上に固定すると、上記テコ作用による巻き爪の弾性的な矯正力がそのまま保持されて、長時間に亘って安定した矯正力を発揮させることができる。また、巻き爪矯正具本体１の一側部に設けている凸円弧状に張り出している患部保護部1aによって、巻き爪の食い込みによって生じている炎症部分を被覆してズボンの裾やその他の外力がこの炎症部分に当たるのを防止している。   Next, when the lever piece 3 pressed against the upper surface of the nail B is fixed on the back of the finger by the adhesive tape 6 as shown in FIGS. 5 and 6, the elastic correction force of the wound nail by the lever action is maintained as it is. As a result, a stable correction force can be exhibited over a long period of time. In addition, the affected part protection part 1a projecting in a convex arc shape provided on one side of the ingrown nail corrector main body 1 covers the inflamed part caused by the encroachment of the ingrown nail to skirt the trousers and other external forces. Prevents it from hitting this inflamed part.

なお、巻き爪矯正具本体１の両側部に患部保護部1a、1aを設けているので、巻き爪が指の他側部側に発生している場合には巻き爪矯正具Ａを爪の他側部上に配設して巻き爪矯正具本体１の他側部に設けている患部保護部1aにより患部を被覆することができるが、被覆したい側のみに患部保護部1aを設けた構造としておいてもよい。   In addition, since the affected part protection parts 1a and 1a are provided on both sides of the curly nail corrector main body 1, when the curly nail is generated on the other side of the finger, the curly nail corrector A is attached to the nail. The affected part can be covered with the affected part protection part 1a provided on the other side part of the ingrown nail corrector body 1 disposed on the side part, but the affected part protection part 1a is provided only on the side to be covered. It may be left.

また、以上の実施例においては、巻き爪を矯正する係止片部２を巻き爪矯正具本体１の先端一個所のみに設けた巻き爪矯正具Ａを示したが、図７に示すように、巻き爪矯正具本体１の先端から下方に折り返し屈曲している部分を二股状に分岐させて二つの係止片部２、２に形成しておいてよい。その他の構造については上記実施例と同じであるので、同一部分に同一符号を付して詳細な説明を省略する。なお、巻き爪矯正具Ａの使用に際して、レバー片３の上面から指の表面にかけて貼着することにより、レバー片３を爪上に押し付けた状態に保持するためテープとして、粘着テープ６を使用しているが、救急絆創膏やそのたの固定用テープを使用してもよい。   Moreover, in the above Example, although the curly nail correction tool A which provided the latching piece part 2 which corrects a curly nail only in one point of the front-end | tip of the curl nail correction tool main body 1 was shown, as shown in FIG. The part bent and bent downward from the tip of the curly nail corrector main body 1 may be bifurcated to form the two locking pieces 2 and 2. Since other structures are the same as those in the above embodiment, the same parts are denoted by the same reference numerals and detailed description thereof is omitted. When using the curly nail corrector A, the adhesive tape 6 is used as a tape to hold the lever piece 3 on the nail by sticking it from the upper surface of the lever piece 3 to the surface of the finger. However, emergency bandages and other fixing tapes may be used.
