Description
本願は、ネイル施術の下処理（甘皮処理、角質処理、ジェルネイル、アクリルスカルプチュア）、人工爪の除去に用いるネイル施術用ハンドピースの構造に関する。より具体的には従来例に係るネイル施術用ハンドピースと比較すると、本願では爪の丸みに合わせてより繊細なビット操作を可能とするために、ネイル施術用ハンドピースの筐体に指が係合可能な指固定具を追加したことを特徴とする指固定具付きネイル施術用ハンドピースの構造に関する。本願ではこの指固定具と係合する指は一般的には中指であるが、中指には拘らず他の指、例えば人差し指や薬指と係合する構造でもよい。なおネイル施術用ハンドピースに指固定具を追加装備する主な目的は、指を引っ掛けてドリルビット先端を微細にコントルールできる「引っ掛かり」構造を達成するためである。 The present application relates to the structure of a nail treatment handpiece used for pre-treatment of nail treatments (cuticle treatment, keratin treatment, gel nails, acrylic sculpture) and removal of artificial nails. More specifically, compared to the conventional handpiece for nail treatment, in the present application, the finger is engaged with the casing of the handpiece for nail treatment in order to enable more delicate bit operation according to the roundness of the nail. The present invention relates to the structure of a handpiece for nail treatment with a finger fixing device, which is characterized in that a finger fixing device that can be combined with the finger fixing device is added. In the present application, the finger that is engaged with this finger fixing device is generally the middle finger, but it is not limited to the middle finger, but may have a structure that engages with other fingers, such as the index finger or the ring finger. The main purpose of adding a finger fixing device to a handpiece for nail treatment is to achieve a "catch" structure in which the tip of the drill bit can be minutely controlled by hooking the finger.
一般的にネイルサロンや美容サロンで行われるネイル施術とは、角質化した余分な皮膚の除去、爪の表面についた薄皮（ルーススキン）と呼ばれる物の除去を行った後に、爪にマニキュアやジェルを1色のみ塗るだけでなく、ストーンやホログラムを乗せてみたり、カラフルな模様や絵を描いたり、いわば指の爪をキャンバスに見立てアート感覚で自由にデザインすることを指称する。その際、人工爪接着の下地を準備するために甘皮除去や爪表面を極浅く削る(サンディング)、そのサンディング処理された爪にネイルジェルの塗布及びネイルアートが施される。この甘皮除去やサンディング処理に、近年ネイル施術用ハンドピースが使用されることが多い。すなわちそのネイル施術用ハンドピースに各種形状のビットを装着し、爪の各部位毎の甘皮除去やサンディング処理が行われる。一般的なネイル施術用ハンドピース１００は図９（Ａ）に示すような構造となっている。また図９（Ｂ）は、実際にハンドピース１００を握持した斜視図である。なおネイル施術用のハンドピースはストレート(直線型)が多く、以下の記述ではストレートを例にとり、ネイルサロン(いわば爪の美容院に相当する)で使用されている従来例に係るネイル施術用ハンドピースは、非常に機能的構造を有しているが、使用されて間もない為、詳細な諸点において以下の諸点でなお改良の余地が存在する。 Nail treatments, which are generally performed at nail salons and beauty salons, involve removing excess keratinized skin and removing what is called loose skin on the surface of the nails, and then applying nail polish or gel to the nails. It refers to not just painting your nails in one color, but also putting stones or holograms on them, drawing colorful patterns or pictures, and using your fingernails as a canvas to freely create designs with an artistic feel. At that time, the cuticle is removed and the nail surface is shaved very shallowly (sanding) in order to prepare the base for adhering the artificial nail. Nail gel is applied and nail art is applied to the sanded nail. In recent years, nail treatment handpieces have often been used for this cuticle removal and sanding treatment. That is, bits of various shapes are attached to the nail treatment handpiece, and cuticle removal and sanding are performed for each part of the nail. A general nail treatment handpiece 100 has a structure as shown in FIG. 9(A). Moreover, FIG. 9(B) is a perspective view of the handpiece 100 actually gripped. Note that most nail treatment handpieces are straight (straight line type), and the following description uses a straight handpiece as an example, and refers to a conventional nail treatment hand used in a nail salon (equivalent to a nail beauty salon). Although the piece has a very functional structure, since it has only recently been used, there is still room for improvement in the following detailed points.
従来例に係るネイル施術用ハンドピースの第１の問題点として、ネイルアート業界の主役である比較的若い女性の多くが、正しくハンドピースを握持することが出来ない点である。すなわちハンドピースを正しく握持する以前の問題として、「箸を正しく持って使える」割合は、年齢とともに増える傾向にあるものの、小学校全体で15.7％、中学校全体で23.1％、高校で23.7％と、２割強に止まり、更に親の世代（26歳～50歳）でさえも、いずれも50％台前半で推移しており、約半数の親が箸を正しく使えていないという驚くべき現実がある。また同様に、「鉛筆を正しく持って使える」割合も、どの学齢段階においても１割以下と極端に低く、加齢による増加もあまりみられない。親の世代をみても、30歳代～40歳代の前半までは僅か15％前後、46～50歳は27.5％と、正しく持てる人が３割にも満たないのが現実である。なおこれ等のデータは決して誇張した数字ではなく、1998年文部科学省の「青少年の生きる力を育むための総合的調査研究」から引用した信頼性が高いデータである。従ってこの様な基礎的な生活技術が欠落した若い女性が、いきなりネイル施術用のハンドピースを初めから正しく握持して使いこなすのは至難の業と言わねばならない。特に本願発明者がネイルの講師として多くの講習会で接した受講生には、ハンドピースについて正しい握持の仕方から教授しなければならないのが現実であり、従って既存のハンドピースの構造は、誰でも最初から正しく握持できる構造とはなっていないという欠点を有している。 The first problem with the conventional nail treatment handpiece is that many relatively young women, who are the main players in the nail art industry, are unable to grip the handpiece correctly. In other words, the percentage of people who are able to properly hold and use chopsticks, which is a problem before grasping the handpiece correctly, tends to increase with age, but it was 15.7% in elementary schools, 23.1% in junior high schools, and 23.7% in high schools. The percentage remains at just over 20%, and even among the parents' generation (26 to 50 years old), the percentage remains in the low 50s, and there is a surprising reality that approximately half of parents cannot use chopsticks properly. . Similarly, the percentage of students who can ``hold and use a pencil correctly'' is extremely low at less than 10% at all school age levels, and does not show much of an increase with age. Looking at the generation of parents, only around 15% of people in their 30s to early 40s and 27.5% of people between 46 and 50 years old, so the reality is that fewer than 30% of people have the right skills. These data are by no means exaggerated numbers, and are highly reliable data taken from the 1998 Ministry of Education, Culture, Sports, Science and Technology's ``Comprehensive research and research to foster youth's zest for life''. Therefore, it must be said that it is extremely difficult for a young woman who lacks such basic life skills to suddenly grasp and use a nail treatment handpiece correctly from the beginning. In particular, the reality is that the present inventor has had to teach the students, who have attended many seminars as a nail instructor, from the correct way to grasp the handpiece, and therefore the structure of the existing handpiece is It has the disadvantage that it is not structured so that anyone can grasp it correctly from the beginning.
従来例に係るネイル施術用ハンドピースの第２の問題点として、これは本願発明の中心的課題であるが、既存のハンドピース１００は先端に装着したドリルビットを下方へ当接させ難い構造である点である。再び図９（Ａ）を参照にして以下具体的に述べる。ハンドピース１００の重心Ｏを通る軸芯をＸ軸、親指と人差し指で摘まむ点（ＡおよびＢ１）を通りＸ軸と直交する軸をＹ軸、そしてその交点（重心Ｏ）からの垂直方向をＺ軸とする。正しいハンドピースの握持の仕方は（A）に示すように、ハンドピースをＹ軸方向の親指末節との接点であるＡ点と、人差し指末節との接点であるＢ１点との２点で摘まみ、さらに人差し指基節近傍のＢ２点、または（B）に示すように指間部にハンドピースを乗せて安定的に保持する。そして安定的に保持したハンドピース１００をネイルアートの施術者は手首Ｓでスナップを効かせつつ微細にコントロールすることで、先端のドリルビットを被施術者の爪の上や指周りで左右に動かすことになる。このハンドピースの握り方は、上述の鉛筆のコントロール方法と実質上は同一である。しかしながら歯科の医療行為とは異なりネイルアートでは、比較的長時間にわたりこの動作を繰り返しつつ爪の表面を削り（サンディングして）、例えば爪表面の汚れを完全に除去してジェルと爪を密着させる等のネイル処理を行う。この場合、ドリルビットの先端を爪表面上から遠ざけるにはＣ点で中指を少し押し上げれば済むが、反対にドリルビットの先端を爪表面に当接させる場合、つまりドリルビットで爪に対してサンディング処理等を行う場合には、中指でハンドピースをＺ軸下方へ押し下げるには中指は全く無力である。理由はハンドピース１００自体に、中指を係合させる「引っ掛かり」構造が全く無いためである。そのためドリルビットの先端を爪表面に当接させる場合には、親指と人差し指でＡ点とＢ１点を強く挟持して押し下げるのと同時に、ドリルビット先端から比較的遠いＢ２点または指間部をスナップ点Ｓで押し上げることで、ドリルビットを爪に対して当接させることが初めて可能となる。ただしドリルビットから手首のスナップ点Ｓまでの距離が遠いため、スナップの動きによってドリルビットを微細にコントロールすることは難しく、そのため親指末節との接点であるＡ点と人差し指末節との接点であるＢ１点での握持に負荷が集中し易い傾向がある。換言すると現状のネイル施術用ハンドピース１００を流用するネイルアート操作では、爪表面での繊細なドリルビット・コントロールを長時間にわたり行うのは困難であるという欠点を有している。そのためＸ軸方向のドリルビット２０からより近い点で、ドリルビット先端を微細にコントロールできる「引っ掛かり」構造が求められる。以上を要約すれば、問題点として、多くの人はハンドピースを強く握り、ドリルビットを爪に対して主に人差し指や親指で上からの圧力を掛け過ぎることにより爪を削り過ぎてしまう点、および人差し指や親指のみで操作することにより、ビット先端の可動域が直線的かつ狭くなるという構造上の問題が存在する。
A second problem with the conventional handpiece for nail treatment, which is a central problem of the present invention, is that the existing handpiece 100 has a structure that makes it difficult for the drill bit attached to the tip to contact downward. That's a certain point. This will be specifically described below with reference to FIG. 9(A) again. The axis passing through the center of gravity O of the handpiece 100 is the X axis, the axis passing through the points (A and B1) pinched between the thumb and index finger and perpendicular to the X axis is the Y axis, and the vertical direction from the intersection (center of gravity O ) is the Y axis. Let it be the Z axis. As shown in (A), the correct way to grip the handpiece is to grip the handpiece at two points: point A, which is the point of contact with the distal phalanx of the thumb in the Y-axis direction, and point B1, which is the point of contact with the distal phalanx of the index finger. Place the handpiece at point B2 near the base of the index finger, or between the fingers as shown in (B), and hold it stably. Then, the nail art practitioner holds the handpiece 100 stably and uses the wrist S to make a snap while finely controlling the tip to move the drill bit at the tip from side to side over the nail and around the finger of the patient. It turns out. This method of gripping the handpiece is substantially the same as the method of controlling the pencil described above. However, unlike dental medical procedures, in nail art, this action is repeated over a relatively long period of time to scrape (sand) the surface of the nail, for example, to completely remove dirt from the nail surface and ensure that the gel adheres to the nail. Perform nail treatments such as In this case, in order to move the tip of the drill bit away from the nail surface, all you need to do is push up your middle finger a little at point C, but on the other hand, if you want the tip of the drill bit to come into contact with the nail surface, in other words, When performing a sanding process or the like, the middle finger is completely powerless to push the handpiece down in the Z-axis direction. This is because the handpiece 100 itself has no "catch" structure for engaging the middle finger. Therefore, when bringing the tip of the drill bit into contact with the surface of the nail, firmly pinch points A and B1 with your thumb and forefinger and press down, while at the same time snapping point B2 or the area between your fingers that is relatively far from the tip of the drill bit. By pushing up at point S, it becomes possible for the first time to bring the drill bit into contact with the pawl. However, since the distance from the drill bit to the snap point S on the wrist is long, it is difficult to finely control the drill bit by the snap movement. There is a tendency for the load to concentrate on gripping at a point. In other words, the current nail art operation using the nail treatment handpiece 100 has the disadvantage that it is difficult to perform delicate drill bit control on the nail surface for a long period of time. Therefore, a "hook" structure is required that allows fine control of the tip of the drill bit at a point closer to the drill bit 20 in the X-axis direction. To summarize the above, the problem is that many people over-grip the nail by gripping the handpiece too tightly and applying too much pressure from above with the drill bit, mainly with their index finger or thumb. There is also a structural problem in that the range of motion of the tip of the bit becomes linear and narrow due to operation using only the index finger or thumb.
そして更に従来例に係るネイル施術用ハンドピースの第３の問題点は、上記の第２の問題点で述べた構造的な不具合のために、ネイル施術用のハンドピースを長時間使用するとネイルアートでは疲れ易いという不具合を有する点である。すなわち第3の問題点は、ネイル施術用ハンドピースで余分な力を入れてしまう点と、ビット先端の可動域が少なくなることで施術時間が延び長時間施術につながる為、肩こりや腱鞘炎、疲れ易いなどの不具合を有する点である。しかしながら既存のハンドピースには、これ等3つの問題に対する具体的な解決策を開示したものは検索されていない。 Furthermore, the third problem with the conventional handpiece for nail treatment is that due to the structural defect mentioned in the second problem above, if the handpiece for nail treatment is used for a long time, However, it has the disadvantage of being easily tiring. In other words, the third problem is that extra force is applied with the handpiece for nail treatment, and the range of motion of the tip of the bit is reduced, which lengthens the treatment time and leads to long treatments, which can lead to stiff shoulders, tendonitis, and fatigue. It has some disadvantages such as being easy to use. However, no existing handpiece has been found that discloses specific solutions to these three problems.
本願発明が解決しようとする第１の課題は、従来のネイル施術用ハンドピース１００では特に若い女性が正しくハンドピースを握持することが出来ない点である。また第２の課題は、ドリルビットを上下方向（Ｚ軸方向）に動かすための作用点であるスナップ点Ｓがドリルビットから遠いため、ドリルビットを微細にコントロールすることが難しい点である。更にまた第３の課題は、ネイル施術用のハンドピースをネイルアートで長時間使用すると疲れ易いという点である。換言すると本願発明が解決しようとする第1の課題は、ネイル施術用ハンドピース１００では操作しやすくハンドピースを握持することが出来ない点であり、また第2の課題は、多くの人はハンドピースを強く握り、ドリルビットを被施術者の爪に対して主に人差し指や親指、中指で上からの圧力をかけ過ぎることにより、爪を削り過ぎてしまう点である。更にまた第3の課題は、ネイル施術用ハンドピースを施術で余分な力を入れて長時間使用すると、肩こりや腱鞘炎、疲れ易いなどの不具合を有する点にある。 The first problem to be solved by the present invention is that the conventional nail treatment handpiece 100 makes it difficult for young women in particular to grasp the handpiece correctly. The second problem is that the snap point S, which is the point of action for moving the drill bit in the vertical direction (Z-axis direction), is far from the drill bit, making it difficult to finely control the drill bit. Furthermore, a third problem is that using a nail treatment handpiece for a long time during nail art can easily cause fatigue. In other words, the first problem that the present invention seeks to solve is that the handpiece 100 for nail treatment cannot be easily operated and gripped, and the second problem is that many people cannot easily hold the handpiece. The problem is that by gripping the handpiece too tightly and applying too much pressure from above with the drill bit, mainly with the index finger, thumb, or middle finger, the nails are ground too much. Furthermore, the third problem is that if a handpiece for nail treatment is used for a long time with excessive force during treatment, it may cause problems such as stiff shoulders, tendonitis, and easy fatigue.
上記課題を解決するために本願発明では、ドリルビット先端を微細にコントロールできる「引っ掛かり」構造として、ネイル施術用ハンドピースの筐体に指が係合可能な指固定具を追加装備したことを最も主要な特徴とする。この指固定具は、ネイル施術用のハンドピースの重心から先端に取付けたドリルビット側の筐体に、この筐体から突出するように取付けられている。そしてハンドピースの筐体を複数本の指で摘まみ、かつこの指固定具に人差し指、中指、または薬指の何れかの指の末節または中節を係合させる。これにより「引っ掛かり」構造を有しない従来例に係る一般的なネイル施術用のハンドピースと比較すると、本願の指固定具付きネイル施術用ハンドピースでは前述の指固定具に所定の指を係合させることにより、ドリルビットの先端を微細にコントロールすることが可能となる。
In order to solve the above problems, the present invention has the most advantageous feature of adding a finger fixing device to the casing of the nail treatment handpiece, which allows fingers to engage , as a "catch" structure that allows fine control of the tip of the drill bit. Main characteristics. This finger fixture is attached to a casing on the side of a drill bit attached to the tip of the handpiece for nail treatment so as to protrude from the casing. Then, the casing of the handpiece is grasped with a plurality of fingers, and the distal or middle phalanx of the index finger, middle finger, or ring finger is engaged with the finger fixing tool. As a result, compared to a conventional handpiece for general nail treatment that does not have a "catch" structure, the handpiece for nail treatment with a finger fixation device of the present application allows a predetermined finger to be engaged with the finger fixation device described above. This makes it possible to finely control the tip of the drill bit.
このように本願発明に係る指固定具付きネイル施術用ハンドピースでは、筐体から「引っ掛かり」構造としての指固定具が突出するように構成されているためネイル施術の初心者でも扱い易く、それと同時にこの突出した指固定具に指を係合させるため、従来例と比較するとドリルビットに近い点に爪に対する当接作用点を置くこととなり、これによりドリルビット操作を微細に行うことが可能となる。また併せて手首によりドリルビット先端の可動域拡大と爪の丸みに合わせた、ドリルビット操作のより繊細なコントロールが可能となる利点を有する。更にまた、指で「引っ掛かり」構造としての指固定具を軽く押し下げることで、ドリルビットを被施術者の爪表面と当接させることが可能となり、長時間に渡るネイルアート操作でも施術者が疲れにくいという利点を有する。 In this manner, the handpiece for nail treatment with a finger fixing device according to the present invention is configured such that the finger fixing device as a "catch" structure protrudes from the housing, making it easy to handle even for beginners in nail treatment, and at the same time. In order to engage the finger with this protruding finger fixing device, the point of contact with the nail is placed closer to the drill bit than in the conventional example, and this makes it possible to perform minute operations on the drill bit. . In addition, the wrist has the advantage of expanding the range of motion of the tip of the drill bit and allowing more delicate control of the drill bit operation in accordance with the roundness of the claw. Furthermore, by lightly pressing down on the finger fixing device, which has a "catch" structure, it is possible to bring the drill bit into contact with the surface of the nail of the patient, which reduces the fatigue of the practitioner even during long nail art operations. It has the advantage of being difficult to use.
図１（Ａ）は本願発明に係る指固定具１０を装着した指固定具付きネイル施術用ハンドピース１の概念図である。本願発明の指固定具付きネイル施術用ハンドピース１は、図９に示す従来例に係るネイル施術用のハンドピース１００と対比すると、指固定具１０を装着した点を除き全て同一である。この実施例では、指固定具１０は中指の末節と係合可能な湾曲形状のレバーで構成されている。もちろん係合する指は中指に限定する趣旨ではなく薬指と係合可能であってもよい。また指固定具１０の取付位置は、Ｘ軸、Ｙ軸、そしてＺ軸の交点である指固定具付きネイル施術用ハンドピース１の重心ＯからＸ軸のドリルビット２０側で、Ｚ軸下方に向け、指が係合する位置に取り付けられる。指固定具１０の形状は曲線状のレバーに限定せず、直線状でも円形でも、その形状は指と係合し易ければ特に限定はしない。材質は金属製、樹脂製等でもよい。指固定具付きネイル施術用ハンドピース１の実際の握持方法は、図１（Ｂ）に示すように指固定具付きネイル施術用ハンドピース１の筐体を指間部に当接させて握持する場合が多い。
FIG. 1(A) is a conceptual diagram of a finger fixing device-equipped nail treatment handpiece 1 equipped with a finger fixing device 10 according to the present invention. The handpiece 1 for nail treatment with a finger fixing device of the present invention is completely the same as the handpiece 100 for nail treatment according to the conventional example shown in FIG. 9 except that the finger fixation device 10 is attached. In this embodiment, the finger fixture 10 is comprised of a curved lever that can be engaged with the distal phalanx of the middle finger. Of course, the finger to be engaged is not limited to the middle finger, and may be capable of engaging with the ring finger. The installation position of the finger fixture 10 is from the center of gravity O of the finger fixture-equipped nail treatment handpiece 1, which is the intersection of the X-axis, Y-axis, and Z-axis, to the drill bit 20 side of the X-axis, and below the Z-axis. It is attached in a position where the finger can be engaged. The shape of the finger fixture 10 is not limited to a curved lever, and may be linear or circular, as long as it can be easily engaged with a finger. The material may be metal, resin, etc. The actual method of grasping the hand piece 1 for nail treatment with a finger fixing device is as shown in FIG. often have.
次に指固定具１０の指固定具付きネイル施術用ハンドピース１への取付は、第１実施例として図２（Ａ）に示すようにハンドピースの筐体にネジで螺合させる湾曲形状のレバーで構成するネジ式指固定具１０ａとしてもよい。この場合ハンドピースの筐体には雌ネジ１１を埋設し、基部に雄ネジを設けたレバーで構成するネジ式指固定具１０ａを螺合させる。この様にネジ式指固定具１０aを指固定具付きネイル施術用ハンドピース１の筐体から下方へ突出させることで、従来例に係るハンドピース１００の様な２点操作、すなわち図９（Ａ）に示すＹ軸方向の親指末節との接点であるＡ点と、人差し指末節との接点であるＢ１点とで指固定具付きネイル施術用ハンドピース１を摘まみ、さらに人差し指基節との接点であるＢ２点でハンドピースを乗せて保持する２点操作ではなく、本願発明では更に指の末節をネジ式指固定具１０aに係合させる第３の作用点を加えた３点操作が可能となる。この３点操作により、従来の２点操作と比較して、爪表面へのサンディング動作の微細なコントロールが可能となる利点を有する。 Next, the finger fixing device 10 is attached to the nail treatment handpiece 1 with a finger fixing device, as shown in FIG. 2(A) as a first embodiment. It may also be a screw-type finger fixture 10a composed of a lever. In this case, a female screw 11 is embedded in the casing of the handpiece, and a screw-type finger fixing device 10a constituted by a lever with a male screw provided at the base is screwed together. In this way, by protruding the screw-type finger fixture 10a downward from the housing of the nail treatment handpiece 1 with a finger fixture, two-point operation like the conventional handpiece 100, that is, FIG. ) Pinch the nail treatment handpiece 1 with a finger fixing tool between point A, which is the point of contact with the distal phalanx of the thumb in the Y-axis direction, and point B1, which is the point of contact with the distal index finger, and then the point of contact with the proximal phalanx of the index finger. Instead of a two-point operation in which the handpiece is placed and held at point B2, the present invention enables a three-point operation in which a third point of action is added to engage the distal phalanx of the finger with the screw-type finger fixture 10a. Become. This three-point operation has the advantage of allowing finer control of the sanding operation on the nail surface compared to the conventional two-point operation.
なおネイルアーティストは、当然ではあるが各人によって掌および指長は各々異なる。そのため上述の指固定具付きネイル施術用ハンドピース１の筐体にネジ式指固定具１０aの雄ネジを取り付ける雌ネジ１１を、図２（Ｂ）に示すようにドリルビット２０方向へ直線状に複数個所に設けてもよい。これによりネイルアートの施術者は自己の掌および指長に合わせて、湾曲形状のレバーで構成したネジ式指固定具１０aの取付位置を簡便に変更可能である。 Naturally, nail artists have different palm and finger lengths. Therefore, the female screw 11 for attaching the male screw of the screw-type finger fixture 10a to the housing of the above-mentioned finger fixture-equipped nail treatment hand piece 1 is inserted in a straight line in the direction of the drill bit 20 as shown in FIG. 2(B). They may be provided at multiple locations. This allows the nail art practitioner to easily change the mounting position of the screw-type finger fixture 10a, which is comprised of a curved lever, according to the length of his or her palm and fingers.
従来例に係るネイル施術用のハンドピース１００では、Ｙ軸方向の親指末節との接点であるＡ点と人差し指末節との接点であるＢ１点と、人差し指基節との接点であるＢ２点、との２点操作による作用点がドリルビット２０から遠い位置に置かれている構造と比較すると、本願発明の指固定具付きネイル施術用ハンドピース１では第３の作用点としてのネジ式指固定具１０ａが、図２（Ａ）に示すようにドリルビット２０から比較的近い点に置かれている構造であるため、指の末節の微細な動きをドリルビット２０に伝達させ易く、従ってドリルビット２０の先端を微細にコントロールすることが可能となる。そして図２（Ｂ）の様に複数個所に雌ネジを設けて、ネジ式指固定具１０aの取付位置を使用者であるネイルアーティスト毎に変更可能とすれば、先端のドリルビット２０とネジ式指固定具１０の距離を自在に変更でき、これにより使い勝手が更に良い構成となるように各自で指固定具付きネイル施術用ハンドピース１をテーラーメイド化することも可能となる。 In the conventional nail treatment handpiece 100, a point A is a contact point with the distal phalanx of the thumb in the Y-axis direction, a point B1 is a contact point with the distal index finger phalanx, and a point B2 is a contact point with the proximal phalanx of the index finger. Compared to the structure in which the point of action of the two-point operation is placed at a position far from the drill bit 20, the nail treatment handpiece with finger fixing device 1 of the present invention has a screw-type finger fixing device as the third point of action. 10a is placed relatively close to the drill bit 20 as shown in FIG. This makes it possible to finely control the tip of the tip. If female screws are provided at multiple locations as shown in FIG. 2(B), and the mounting position of the screw-type finger fixing device 10a can be changed for each nail artist, then the drill bit 20 at the tip and the screw-type The distance of the finger fixing device 10 can be freely changed, and thereby each person can tailor-make the nail treatment handpiece 1 with the finger fixing device to obtain a configuration that is even more convenient to use.
更に上述の実施例１のように指固定具付きネイル施術用ハンドピース１の筐体に複数個の雌ネジを取り付ける構成に代わり、第２実施例として図３に示すように、取付位置調整機構１０ｂ-１を埋設したラチェット式指固定具１０ｂとしてもよい。すなわち指固定具付きネイル施術用ハンドピース１の筐体に溝状の取付位置調整機構１０ｂ-１を埋設し、これにラチェット式指固定具１０ｂを係合させるラチェット構造として、この溝に沿ってレバーで構成したラチェット式指固定具１０ｂを任意に摺動移動させる構造である。そして例えばラチェット式指固定具１０ｂの取付基部を拡幅するように付勢された構造とし、この拡幅付勢した取付基部が取付位置調整機構１０ｂ-１のラチェットと係合することにより、ラチェット式指固定具１０ｂを固定することが出来る。なおこの取付位置調整機構自体は、従来例に多く開示されされているため詳述は割愛する。 Furthermore, instead of the configuration in which a plurality of female screws are attached to the housing of the finger fixing handpiece 1 as in the first embodiment described above, as shown in FIG. 3 as a second embodiment, an attachment position adjustment mechanism is provided. 10b-1 may be used as a ratchet type finger fixture 10b embedded therein. That is, a groove-shaped attachment position adjustment mechanism 10b-1 is embedded in the housing of the nail treatment handpiece 1 with a finger fixing device, and a ratchet structure in which the ratchet type finger fixing device 10b is engaged with the mounting position adjusting mechanism 10b-1 is installed along this groove. It has a structure in which a ratchet type finger fixture 10b composed of a lever is slidably moved. For example, the mounting base of the ratchet type finger fixture 10b is biased to widen the width, and the width biased mounting base engages with the ratchet of the mounting position adjustment mechanism 10b-1. The fixture 10b can be fixed. Note that this attachment position adjustment mechanism itself has been disclosed in many prior art examples, so a detailed description thereof will be omitted.
更にまたネイル施術用のハンドピースが既に広く入手可能である現状を考慮して、既存のネイル施術用ハンドピースに簡便に指固定具１０を装着する構造として図４に示すような貼付式指固定具１０ｃがある。この実施例のレバーで構成した指固定具は、粘着層を裏面に有する貼付板に固定されている。そしてこの固定板を既存のネイル施術用ハンドピースの任意の箇所に貼付するという極めて簡便な構成である。従ってこの貼付式指固定具１０ｃは、ハンドピースの筐体とは別個のオプションとして購入可能である。なお粘着層には当然保護膜を有しており、保護膜を剥がして、如何なるタイプの既存のネイル施術用ハンドピースへの後付けが可能である。なお粘着層を裏面に有する貼付板を、ハンドピースの筐体の曲面に合うように構成してもよい。曲面が多少異なっても粘着層が十分にその差を吸収して粘着可能である。こうした粘着タイプの構成は、例えば携帯電話の裏面に貼付する携帯電話保持具等で広く用いられているため、詳述は省略する。 Furthermore, considering the current situation in which handpieces for nail treatment are already widely available, an adhesive type finger fixation device as shown in FIG. There is a tool 10c. The finger fixture made up of the lever of this embodiment is fixed to an adhesive plate having an adhesive layer on the back surface. This fixing plate can be attached to any desired location on an existing handpiece for nail treatment, making it extremely simple. Therefore, this stick-on finger fixture 10c can be purchased as an option separate from the handpiece housing. Note that the adhesive layer naturally has a protective film, and by peeling off the protective film, it can be retrofitted to any type of existing nail treatment handpiece. Note that the attachment plate having the adhesive layer on the back surface may be configured to fit the curved surface of the housing of the handpiece. Even if the curved surfaces are slightly different, the adhesive layer can sufficiently absorb the difference and adhere. Such an adhesive type structure is widely used, for example, in a mobile phone holder that is attached to the back of a mobile phone, so a detailed description thereof will be omitted.
同様に既存のハンドピースに簡便に指固定具を装着する他の構造として、図５に示すようなリング式指固定具１０ｄがある。このリング式指固定具１０ｄには、リングが設けられている。このリングにテーパー状のハンドピース先端を挿入することで、このリング式指固定具１０ｄをテーパー状のハンドピースの筐体に固定可能である。またリングの途中に例えばリング径を調整可能とするリング直径調整機構を付加することでリング直径を微調整する構成とし、これにより使用するネイルアーティストの指の長さに応じて、このリング式指固定具１０ｄの取付位置をテーパー状のハンドピースの所定の位置に微調整して取り付けることも可能である。なおこのリングの直径を調整するリング直径調整機構も従来例に数多く存在するため詳細は割愛する。 Similarly, as another structure for easily attaching a finger fixture to an existing handpiece, there is a ring-type finger fixture 10d as shown in FIG. This ring type finger fixture 10d is provided with a ring. By inserting the tip of the tapered handpiece into this ring, the ring-type finger fixing device 10d can be fixed to the housing of the tapered handpiece. In addition, by adding a ring diameter adjustment mechanism in the middle of the ring, the ring diameter can be finely adjusted. It is also possible to finely adjust the attachment position of the fixture 10d and attach it to a predetermined position on the tapered hand piece. Note that there are many ring diameter adjustment mechanisms in the prior art for adjusting the diameter of this ring, so the details will be omitted.
更にまた上記実施例４で述べたようにネイル施術用のハンドピースが既に広く入手可能である現状を考慮して、図６（Ａ）および（Ｂ）には既存のハンドピースに指固定具１０を簡便に装着する他の構造として、人差し指を挿入するリング１とネイル施術用ハンドピースの筐体へ挿入固定するリング２を有するダブルリング式指固定具１０ｅが開示されている。リング１とリング２は相互に連結され、かつ回動可能であり、挿入する人差し指の挿入角度に応じて回転調整することが可能となっている。上述の実施例1から実施例３では、主として中指または薬指で指固定具１０を操作する構成であるが、本実施例４では親指と中指でハンドピースの筐体を保持し、人差し指をリング１へ挿入して操作を行う。なお人差し指を挿入するリング１の形状は、図示するような線状のリングに限定する趣旨ではなく指に自然にフィットする形状であれば如何なる形状でも良い。また上述の筐体へ挿入固定するリング２は、リング状であり筐体に対して回転可能である。そのため任意の回転位置へリング２を回動させ、かつその回転位置でリング１へ挿入可能な任意の指を挿入することで、当該ダブルリング式指固定具１０ｅを使用することが可能である。 Furthermore, as described in the above-mentioned Example 4, taking into account the current situation that handpieces for nail treatment are already widely available, FIGS. As another structure for easily attaching the handpiece, a double ring type finger fixing device 10e has been disclosed which has a ring 1 into which the index finger is inserted and a ring 2 which is inserted and fixed into the housing of the nail treatment handpiece. Ring 1 and ring 2 are interconnected and rotatable, and can be rotated according to the insertion angle of the index finger. In the first to third embodiments described above, the finger fixing device 10 is operated mainly with the middle finger or the ring finger, but in the fourth embodiment, the housing of the handpiece is held with the thumb and middle finger, and the index finger is attached to the ring 1. Insert and operate. The shape of the ring 1 into which the index finger is inserted is not limited to the linear ring shown in the figure, but may be of any shape as long as it fits the finger naturally. Further, the ring 2 inserted and fixed into the above-mentioned casing is ring-shaped and rotatable with respect to the casing. Therefore, it is possible to use the double ring type finger fixing tool 10e by rotating the ring 2 to an arbitrary rotational position and inserting any insertable finger into the ring 1 at the rotational position.
更にまた上記のようにネイル施術用のハンドピースが既に広く入手可能である現状を考慮して、図７には既存のハンドピースに指固定具１０を簡便に装着する他の構造として、円錐台状の基部に取り付けた中空テーパー状のキャップ構造であるキャップ式指固定具１０ｆが開示されている。この中空テーパー状のキャップ式指固定具１０ｆは、一般的なネイル施術用のハンドピースの筐体に被せるようにして装着する。またこのキャップ式指固定具１０ｆはハサミで切断可能な素材、例えばプラスチックで構成し、各ネイルアーティストが所有する既存のネイル施術用ハンドピースの筐体直径に合わせて切取り線（図中の点線）で切り取る構成としてもよい。そしてその切取ったキャップ式指固定具１０ｆにハンドピースの先端を挿入する。ハンドピースは先端に向けてテーパー状となっているため、ハンドピースの直径が切り取ったリング直径に合致するハンドピース筐体の特定の位置で、このキャップ式指固定具１０ｆをハンドピースに固定装着することが可能である。従って各ネイルアーティストは、所有する自己のハンドピースの所定の位置にこのキャップ式指固定具１０ｆが係止するように、円錐台の途中を切り取れば、任意の位置でこのキャップ式指固定具１０ｆをハンドピース筐体に固定装着することが可能である。 Furthermore, considering the fact that handpieces for nail treatment are already widely available as described above, FIG. A cap-type finger fixture 10f is disclosed which has a hollow tapered cap structure attached to a base of a shape. This hollow tapered cap-type finger fixing device 10f is attached so as to cover the housing of a general nail treatment handpiece. In addition, this cap-type finger fixing device 10f is made of a material that can be cut with scissors, such as plastic, and is cut along the cutout line (dotted line in the figure) according to the casing diameter of the existing nail treatment handpiece owned by each nail artist. It may also be configured to be cut out. Then, insert the tip of the handpiece into the cut-off cap-type finger fixture 10f. Since the handpiece is tapered toward the tip, this cap-type finger fixture 10f is fixedly attached to the handpiece at a specific position on the handpiece housing where the diameter of the handpiece matches the diameter of the cut ring. It is possible to do so. Therefore, each nail artist can place the cap-type finger fixture 10f at any desired position by cutting out the middle of the truncated cone so that the cap-type finger fixture 10f locks in a predetermined position on his or her own handpiece. can be fixedly attached to the handpiece housing.
最後に図８には、ハンドピースの筐体自体に中指または薬指を引っ掛ける窪みを具備する「くぼみ式指固定具１０ｇ」が開示されている。この実施例は、「くぼみ」に被施術者の爪が不用意に引っ掛からず、安全を考慮した構成であると共に、全体の構成をコンパクトにするためである。
Finally, FIG. 8 discloses a "recessed finger fixture 10g" which has a recess in the handpiece housing itself for hooking the middle finger or ring finger . This embodiment is designed to prevent the patient's nails from getting caught inadvertently in the "indentations" and is designed with safety in mind, as well as to make the overall structure compact.
指固定具１０をハンドピースの重心Ｏよりドリルビット２０側に取り付けることにより、不慣れな若いネイルアート研修生でも正しくハンドピースを握持できる。またより重要な点として指固定具１０に指を係合させることで、Ｚ軸下方への当接作用点がドリルビットに更に近づくため、ドリルビット先端の繊細なコントルールが可能となる。そして指を指固定具に軽く当てるだけで、ドリルビットを爪表面に対して適切に当接させることが可能となるため、長時間に渡るネイルアート操作でも疲れ難いという利点を有する。また既存のネイル施術用ハンドピースにも各種の指固定具１０ａ～１０ｇをオプションとして簡便に取り付けることが可能となり、Ｘ軸方向のドリルビット２０からより近い点で、ドリルビット先端を微細にコントロール出来るという利点を有する。 By attaching the finger fixture 10 closer to the drill bit 20 than the center of gravity O of the handpiece, even an inexperienced young nail art trainee can correctly grasp the handpiece. More importantly, by engaging the finger with the finger fixture 10, the point of contact in the downward direction of the Z-axis approaches the drill bit, allowing delicate control of the tip of the drill bit. Since it is possible to bring the drill bit into proper contact with the nail surface by simply touching the finger fixture lightly with the finger, there is an advantage that even long nail art operations are less tiring. In addition, various finger fixtures 10a to 10g can be easily attached to existing nail treatment handpieces as options, allowing fine control of the tip of the drill bit at a point closer to the drill bit 20 in the X-axis direction. It has the advantage of
