Description

本発明は、病変などによって爪の甲が分厚く盛り上がった部分（鉤わん爪）を除去し整形するのに好適な爪整形具に関する。 The present invention relates to a nail shaping tool suitable for removing and shaping a portion where the nail plate is raised thickly due to a lesion or the like.

例えば、爪水虫（爪白癬）に罹った足の爪は、爪甲（爪の甲部分）が分厚く盛り上がって変色し「鉤わん爪」と称される状態になる。この鉤わん爪を治療する際には、爪甲の盛り上がり部分を削って平坦にし、その平坦部分に治療薬を塗布して爪内面側へ浸透させることになる。従来は、盛り上がり部分を爪用のやすりで削ることにより、爪甲を薄く平坦に整形していた。因みに、一般に使用される喰切り型の爪切りや、ニッパー形の爪切り（特許文献１）では、大きく盛り上がった鉤わん爪を一対の切刃の間に挟むこと、これ自体が困難なため、鉤わん爪を除去する用途には供し得ない。
特開２０００−５０９４２号公報（段落番号０００８、図１） For example, a toenail suffering from nail athlete's foot (claw tinea) is raised and discolored with a thick nail plate (a part of the nail plate) into a state referred to as a “wrinkle nail”. When treating this wrinkle nail, the raised part of the nail plate is shaved and flattened, and a therapeutic agent is applied to the flat part to penetrate into the inner surface of the nail. Conventionally, the nail plate has been shaped thinly and flatly by scraping the raised part with a nail file. By the way, in the commonly used bite type nail clipper and nipper type nail clipper (Patent Document 1), it is difficult to sandwich a large raised nail clipper between a pair of cutting blades. It cannot be used for the purpose of removing wrinkles.
JP 2000-50942 A (paragraph number 0008, FIG. 1)

しかし、やすりで鉤わん爪を削り落とす上記の整形作業は、盛り上がり部分の除去に多くの時間と手間とが掛かるうえ、やすりで盛り上がり部分を削り落とす際に、病変した爪の粉が周辺に飛散する。 However, the above-mentioned shaping work that scrapes off the crunchy nail with a file takes a lot of time and effort to remove the raised part, and when the raised part is scraped off with a file, the affected nail powder is scattered around To do.

そこで、本発明の目的は、爪甲の盛り上がり部分を鉋で削るようにして除去できる、鉤わん爪の整形に好適な爪整形具を提供することにある。本発明の目的は、爪甲の盛り上がり部分を簡便に除去して整形できる爪整形具を提供することにある。 Therefore, an object of the present invention is to provide a nail shaping tool suitable for shaping a crab nail, which can be removed by scraping the raised portion of the nail plate. An object of the present invention is to provide a nail shaper that can easily remove and shape a raised portion of a nail plate.

本発明の爪整形具は、Ｘ字状に組まれて軸３で交差揺動可能に連結される一対の挟み体１・２を備えている。両挟み体１・２は、軸３の一側に設けられる握り柄４・５と、軸３の他側に設けられる作用腕６・７とをそれぞれ含む。両作用腕６・７の対向面の一方には、爪先ないし指先を受け止める受部１１が形成され、他方には削り刃１２が形成されており、削り刃１２で爪甲の盛り上がり部分を爪基端側から爪先へ向かって削ることができるようにしたものである。 The nail shaping tool of the present invention is provided with a pair of sandwiching bodies 1 and 2 that are assembled in an X shape and are connected to a shaft 3 so as to be capable of cross-swing. Both sandwiching bodies 1 and 2 include grip handles 4 and 5 provided on one side of the shaft 3 and working arms 6 and 7 provided on the other side of the shaft 3, respectively. A receiving part 11 for receiving a toe or fingertip is formed on one of the opposing surfaces of both working arms 6 and 7, and a shaving blade 12 is formed on the other. It can be cut from the end side toward the toe.

削り刃１２と対向する受部１１の爪受面１５は、凹凸面に形成することができる。削り刃１２における爪受面１５との対向縁に形成された子刃１２ｂは、連続山形状に形成することができる。受部１１は、一方の作用腕６に装着固定したプラスチック製の受ブロック１４で構成することができる。 The claw receiving surface 15 of the receiving portion 11 facing the sharpening blade 12 can be formed on an uneven surface. The child blade 12b formed on the edge of the cutting blade 12 facing the claw receiving surface 15 can be formed in a continuous mountain shape. The receiving part 11 can be constituted by a plastic receiving block 14 attached and fixed to one working arm 6.

本発明の爪整形具によれば、使用時に、爪先ないし指先を受部１１で受け止め、削り刃１２を爪基端側から爪先へ向かって移動させることにより、爪甲の盛り上がり部分を削り刃１２で削ぎ落としながら除去できる。したがって、やすりで盛り上がり部分を削っていた従来の整形作業に比べて、爪の整形が簡便に、しかも短時間で行える。整形作業時に病変した爪の粉が周辺に飛散するのも解消でき、鉤わん爪の整形に好適である。 According to the nail shaping tool of the present invention, at the time of use, the toe or fingertip is received by the receiving part 11 and the shaving blade 12 is moved from the nail proximal side toward the toe to remove the raised portion of the nail plate. Can be removed while scraping. Therefore, the nail can be shaped easily and in a short time compared to the conventional shaping work in which the raised portion is cut with a file. It is also possible to eliminate the nail powder that has been damaged during the shaping operation from being scattered around, and it is suitable for shaping the nail claw.

受部１１の爪受面１５が、凹凸面に形成された爪整形具によれば、爪先ないし指先を爪受面１５で受け止めた状態において、受部１１が爪や指先に沿って滑るのを防止して、爪整形具を爪に対して確りと保持固定でき、より安定した状態で爪整形作業を行うことができる。 According to the nail shaping tool in which the nail receiving surface 15 of the receiving part 11 is formed in an uneven surface, the receiving part 11 can slide along the nail or the fingertip in a state where the toe or fingertip is received by the nail receiving surface 15. Thus, the nail shaping tool can be securely held and fixed to the nail, and the nail shaping work can be performed in a more stable state.

削り刃１２の子刃１２ｂが連続山形状に形成されていると、削り刃１２を爪甲の盛り上がり部分に対して食い込ませやすい。したがって、爪甲の盛り上がり部分を削り刃１２でさらに適確に削ぎ落として、爪の整形を迅速に行える。 If the child blade 12b of the cutting blade 12 is formed in a continuous mountain shape, the cutting blade 12 is likely to bite into the raised portion of the nail plate. Therefore, the raised portion of the nail plate can be further accurately scraped off by the sharpening blade 12 to quickly shape the nail.

作用腕６に装着したプラスチック製の受ブロック１４で受部１１が構成されていると、外形形状や大きさなどが異なる複数種の受ブロック１４を用意しておくことにより、受ブロック１４部分の大きさや形状が異なる爪整形具を簡単にシリーズ化できるうえ、挟み体１・２を共用できる分だけ、シリーズ商品化した爪整形具を低コストで提供できる。爪先や指先に対する爪受面１５の当りが柔らかになる利点もある。 When the receiving portion 11 is configured by the plastic receiving block 14 attached to the working arm 6, by preparing a plurality of types of receiving blocks 14 having different outer shapes and sizes, the receiving block 14 portion Nail shaping tools of different sizes and shapes can be easily made into a series, and the nail shaping tools that have been commercialized as a series can be provided at low cost as much as the clip bodies 1 and 2 can be shared. There is also an advantage that the contact of the nail receiving surface 15 with the toe or fingertip is soft.

（実施例１）図１ないし図４は本発明に係る爪整形具の実施例１を示す。図２に示すように、爪整形具は、Ｘ字状に組まれて軸３で交差揺動可能に連結した一対の挟み体１・２で鋏のように構成する。両挟み体１・２は、軸３の一側に設けられる握り柄４・５と、軸３の他側に設けられる作用腕６・７とをそれぞれ備えている。 (Example 1) FIG. 1 thru | or FIG. 4 shows Example 1 of the nail shaper which concerns on this invention. As shown in FIG. 2, the nail shaping tool is configured like a ridge by a pair of sandwiching bodies 1 and 2 that are assembled in an X shape and are connected so as to be able to cross and swing by a shaft 3. Both sandwiching bodies 1, 2 include grips 4, 5 provided on one side of the shaft 3 and working arms 6, 7 provided on the other side of the shaft 3, respectively.

一対の挟み体１・２を軽快に開閉するために、握り柄４・５は、裁ち鋏の握り部分と同様の涙滴リング状に形成してあって、リング部分に親指と残る四指とを差し込むことができる。リング部分の外面にはプラスチック製のグリップ８を被覆してある。より小さな操作力で爪を削るために、リング部分の直線辺部のほぼ中央に操作力が作用すると想定するとき、操作力の作用点から軸３の中心までの長さは、作用腕６・７の先端から軸３の中心までの長さの約３倍に設定してある。 In order to lightly open and close the pair of sandwiching bodies 1 and 2, the grip patterns 4 and 5 are formed in a teardrop ring shape similar to the grip portion of the cleaver, and the thumb and the remaining four fingers on the ring portion Can be plugged in. The outer surface of the ring portion is covered with a plastic grip 8. When it is assumed that the operating force acts on the center of the straight side of the ring portion in order to cut the nail with a smaller operating force, the length from the operating point of the operating force to the center of the shaft 3 is the acting arm 6. The length from the tip of 7 to the center of the shaft 3 is set to about 3 times.

図４において各作用腕６・７は、それぞれ挟み体１・２の交差平面を越えて折り曲げ形成されており、一方の作用腕６には爪先端縁を受け止める受部１１が形成され、他方の作用腕７には爪甲の盛り上がり部分を削る削り刃１２が形成されている。この実施例では、作用腕６の先端に装着した受ブロック１４で受部１１を構成した。 In FIG. 4, each working arm 6, 7 is formed so as to be bent beyond the intersecting plane of the sandwiching bodies 1, 2. One working arm 6 is formed with a receiving portion 11 for receiving the claw tip edge, and the other The working arm 7 is formed with a shaving blade 12 for shaving the raised portion of the nail plate. In this embodiment, the receiving portion 11 is constituted by the receiving block 14 attached to the tip of the working arm 6.

受ブロック１４は、断面コ字状のポリアセタール製の成形品であり、削り刃１２と対向する壁面に爪先や指先を受け止めるための爪受面１５を有する。滑り止めのために、爪受面１５は連続山形の条歯群からなる凹凸面に形成した。作用腕６と、これに装着の受ブロック１４とは、リベット１６で分離不能に締結されている。 The receiving block 14 is a molded product made of polyacetal having a U-shaped cross section, and has a nail receiving surface 15 for receiving a nail tip and a fingertip on a wall surface facing the cutting blade 12. In order to prevent slipping, the nail receiving surface 15 was formed as an uneven surface composed of a group of continuous chevron teeth. The working arm 6 and the receiving block 14 attached thereto are fastened by a rivet 16 so as not to be separated.

図３において削り刃１２は、爪受面１５へ向かって下り傾斜する削り刃１２ａと、これの先端側の小刃１２ｂとを含み、その反対面側が平坦な片刃構造を採る。図１において小刃１２ｂは直線状に形成してある。なお、ここでの爪整形具は、右利き用を示しており、左利き用の場合には、受部１１と削り刃１２とを左右逆に配置すればよい。図８は爪整形具の外観を示す。 In FIG. 3, the cutting blade 12 includes a cutting blade 12 a that is inclined downward toward the claw receiving surface 15, and a small blade 12 b on the tip side of the cutting blade 12 a, and adopts a single blade structure in which the opposite surface side is flat. In FIG. 1, the small blade 12b is formed linearly. In addition, the nail shaper here is for right-handed use, and in the case of left-handed use, the receiving portion 11 and the cutting blade 12 may be arranged in the left-right direction. FIG. 8 shows the appearance of the nail shaping tool.

使用時には、まず鉤わん爪の爪先を削り刃１２と受部１１とで上下に挟んで直線状に切断する。鉤わん爪は病変によって爪の成分であるケラチンの状態がもろくなっており、削り刃１２と受部１１とで爪先を挟むことができさえすれば、片方の削り刃１２のみで爪先を問題なく切断できる。もちろん、ニッパー型や喰い切り型の爪切りを用いて、爪先を直線状に切断してもよい。このように、爪先を直線状に切断することにより、爪受面１５を爪先の切断面に確りとあてがうことができる。 At the time of use, first, the tip of the hooked nail is vertically cut between the sharpening blade 12 and the receiving portion 11 and vertically. The state of keratin, which is a component of the nail, is fragile due to the lesion, and as long as the nail can be sandwiched between the shaving blade 12 and the receiving part 11, the nail can be removed with only one shaving blade 12 Can be cut. Of course, the tip of the nail may be cut in a straight line by using a nipper type or a bite type nail clipper. In this way, by cutting the toe in a straight line, the nail receiving surface 15 can be surely applied to the cut surface of the toe.

図３に示すように、爪受面１５を爪先にあてがった状態で、削り刃１２を爪甲の盛り上がり部分に食い込ませながら爪基端側から爪先へ向かって移動させて、恰も鉋で木材を削るのと同様にして、爪表面を削り刃１２で削り取る。多くの場合は、削り刃１２が食い込む位置を少しずつずらしながら盛り上がり部分を除去して、爪甲をできるだけ薄く整形する。このように、削り刃１２で爪表面を削ぎ落としながら整形すると、やすりで鉤わん爪を削り落とす場合とは異なり、病変した爪の粉が周りに飛散することはないし、盛り上がり部分をより短い時間で効果的に除去できる。 As shown in FIG. 3, with the nail receiving surface 15 applied to the toe, the cutting blade 12 is moved from the nail base side toward the toe while biting into the raised part of the nail plate, and the wood is removed with the scissors. The nail surface is scraped off with the sharpening blade 12 in the same manner as shaving. In many cases, the raised portion is removed while gradually shifting the position where the cutting blade 12 bites in, and the nail plate is shaped as thin as possible. In this way, when the nail surface is shaved off with the sharpening blade 12, the lesioned nail powder is not scattered around, unlike the case where the nail claw is scraped off with a file. Can be removed effectively.

（実施例２）図５は本発明に係る爪整形具の実施例２を示しており、削り刃１２の小刃１２ｂが連続山形状に形成されていて、盛り上がり部分に対する削り刃１２の食い込みを良くして、削り刃１２が爪表面に沿って滑るのを防止した。他は実施例１と同じであるので、同じ部材には同じ符号を付してその説明を省略する。以下の実施例においても同様に扱う。 (Example 2) FIG. 5 shows Example 2 of the nail shaping tool according to the present invention, in which the small blade 12b of the sharpening blade 12 is formed in a continuous mountain shape, and the biting of the sharpening blade 12 with respect to the raised portion is illustrated. As a result, the shaving blade 12 was prevented from sliding along the nail surface. Since others are the same as those of the first embodiment, the same members are denoted by the same reference numerals and the description thereof is omitted. The same applies to the following embodiments.

（実施例３）図６は本発明に係る爪整形具の実施例３を示しており、前記受ブロック１４を省略して、作用腕６の削り刃１２との対向面に爪受面１５を直接に設けた。この爪受面１５は、実施例１と同様に、連続山形の条歯群からなる凹凸面で形成した。 (Embodiment 3) FIG. 6 shows Embodiment 3 of the nail shaping tool according to the present invention, in which the receiving block 14 is omitted and a nail receiving surface 15 is provided on the surface of the working arm 6 facing the cutting blade 12. Directly provided. As in Example 1, the nail receiving surface 15 was formed as an uneven surface composed of a group of continuous chevron teeth.

（実施例４）図７は本発明に係る爪整形具の実施例４を示しており、基本的には実施例３の爪整形具と同じであるが、実施例２と同様に、削り刃１２の小刃１２ｂを連続山形状に形成して、削り刃１２の食い込みを良くした。 (Example 4) FIG. 7 shows Example 4 of the nail shaping tool according to the present invention, which is basically the same as the nail shaping tool of Example 3, but in the same manner as in Example 2, a sharpening blade Twelve small blades 12b were formed in a continuous mountain shape, and the biting of the cutting blade 12 was improved.

上記の実施例以外に、爪受面１５の滑り止め構造は条歯群で構成するする必要はなく、やすりの表面のような凹凸面で形成してもよい。爪の断面は上凸状に湾曲しているが、削り刃１２はこの爪の断面形状に沿わせて上凸状に湾曲形成することができる。小刃１２ｂは直線状に形成することが好ましいが、必要があれば凹曲状に湾曲形成してもよい。受ブロック１４は、爪先と同時に指先を受け止める構造にすることができる。作用腕６に削り刃１２と同様の切刃を形成しておき、切刃部分に受ブロック１４を着脱可能に装着することができる。一対の挟み体１・２は、握り柄４・５間に配置したばねで開き付勢することができる。握り柄４・５はリング構造にする必要はなく、ニッパーと同様のハンドル構造にしてもよい。 In addition to the above-described embodiment, the anti-slip structure of the nail receiving surface 15 does not need to be formed of a tooth group, and may be formed of an uneven surface such as a file surface. Although the cross-section of the nail is curved in an upward convex shape, the cutting blade 12 can be curved in an upward convex shape along the cross-sectional shape of the nail. The blade 12b is preferably formed in a straight line shape, but may be formed in a concave curved shape if necessary. The receiving block 14 can be configured to receive the fingertip simultaneously with the toe. A cutting blade similar to the cutting blade 12 is formed on the working arm 6, and the receiving block 14 can be detachably attached to the cutting blade portion. The pair of sandwiching bodies 1 and 2 can be opened and biased by a spring disposed between the grips 4 and 5. The grips 4 and 5 do not need to have a ring structure, and may have a handle structure similar to a nipper.
