Description

アイラッシュカーラーEyelash curler
 本発明はアイラッシュカーラーに関する。 The present invention relates to an eyelash curler.
 一般的に、アイラッシュカーラー(まつ毛カール器、ビューラー)は、梃子の原理を用いた構成であって、2本の指を用いるステンレス等の金属で形成されている。 Generally, an eyelash curler (eyelash curler, burer) has a configuration using the principle of leverage, and is formed of a metal such as stainless steel using two fingers.
 しかし、一般的な梃子の原理を用いた金属製のアイラッシュカーラーでは、把持部では1本の金属棒をひねってリング状に成形され、他の部分では金属棒が2本並んで延伸しているため、把持部において金属断面が細く、ホールド性が悪かった。また、金属アレルギーの人は使用できなかった。 However, in the case of a metal eyelash curler using the general leverage principle, a single metal rod is twisted and formed into a ring shape at the grip portion, and two metal rods are stretched side by side at the other portion. In addition, the metal section was thin at the grip portion, and the holdability was poor. Also, people with metal allergies could not use it.
 そこで、金属アレルギーを防いだり、肌あたりをやさしくするため、指が接触する把持部や、まぶたが接触する当接面等に対応する部分を、金属の上から樹脂で部分的に覆ったり、部分的に一部の部材を樹脂で構成するアイラッシュカーラーが提案されている(例えば、特許文献1、特許文献2)。 Therefore, in order to prevent metal allergies and soften the skin, parts corresponding to the gripping parts with which the fingers contact, the contact surfaces with which the eyelids contact, etc. are partially covered with resin from above the metal. There have been proposed eyelash curlers in which some members are made of resin (for example, Patent Documents 1 and 2).
 また、外側に金属を使用せずに、外側全体が樹脂製のアイラッシュカーラーとして、バネを有するアイラッシュカーラーが存在する(例えば、特許文献3)。 ア イ Also, there is an eyelash curler having a spring as an eyelash curler made entirely of resin without using metal on the outside (for example, Patent Document 3).

 しかし、特許文献1や2のように、金属製のアイラッシュカーラーの一部に樹脂部を取りつけたり、一部を樹脂で置き換えたりすると、金属単体のアイラッシュカーラーと比較して、組立てのための製造工程が多くなる分、生産性が低下する。 However, when a resin part is attached to a part of a metal eyelash curler or a part is replaced with resin as in Patent Documents 1 and 2, the manufacturing process for assembling is more complicated than that of a metal single eyelash curler. As the number increases, productivity decreases.
 また、一般的な金属製の形状と同じ形状で樹脂製のアイラッシュカーラーを形成しようとすると、挟み込みのための強度が足りないため、特許文献3に示す、外側全体が樹脂製のアイラッシュカーラーでは、挟み込みのためのバネを設けていた。しかし、バネを設ける分、複雑で大型な構成となってしまった。またこの構成では、梃子を用いる一般的な金属製のアイラッシュカーラーと比較して、外観が類似せず、操作方法が異なる。 In addition, when trying to form a resin eyelash curler in the same shape as a general metal shape, the strength for pinching is insufficient, so that an eyelash curler in which the entire outside is made of resin as shown in Patent Literature 3, A spring was provided. However, the provision of the spring results in a complicated and large configuration. In addition, in this configuration, the appearance is not similar and the operation method is different as compared with a general metal eyelash curler using a lever.
 そこで、本発明は上記事情に鑑み、一般的な金属製の形状よりも大型化することなく、強度を担保して、金属製と同様の操作ができる、樹脂製のアイラッシュカーラーの提供を目的とする。 In view of the above circumstances, an object of the present invention is to provide a resin-made eyelash curler that can perform the same operation as that of a metal, while ensuring strength and without increasing the size of a general metal shape. .

 上側プレス部が一体的に形成された固定部材と、
 下側プレス部が前記上側プレス部に対して、上下に移動可能である作用部材と、
 前記固定部材と係合する部分を支点として回動することで、前記作用部材を上下に移動させる力点部材と、を有しており、

 また、図3を参照して、アーム14に形成された支持穴部15を形成する両側の側面(側壁)には幅方向に貫通する、小孔151A,151Bが形成されている。なお、本構成では、支持穴部15を規定する側面は、アーム14の他部分よりも広い構成を示しているが、他のアーム14と同じ幅であってもよい。 Also, referring to FIG. 3, small holes 151A, 151B are formed in the side surfaces (side walls) on both sides forming the support hole 15 formed in the arm 14 so as to penetrate in the width direction. In this configuration, the side surface that defines the support hole 15 is wider than the other part of the arm 14, but may have the same width as the other arm 14.
 力点部材20は、アーム部21,24と持ち手25を有している。先端側アーム21には、第1の係合孔である先端孔(先端係合孔)22と、第2の係合孔である支点孔(支点係合孔)23とが形成されている。 The power point member 20 has arms 21 and 24 and a handle 25. The distal arm 21 has a distal hole (distal engaging hole) 22 as a first engaging hole and a fulcrum hole (fulcrum engaging hole) 23 as a second engaging hole.
 アーム部(第2のアーム部、柄部、軸部ともいう)21,24は、先端部から連結部を超えて延伸する先端側アーム21と、先端側アーム21とは延伸方向が異なり、持ち手25の内側の部分である直線部251(図3参照)と同じ方向に延伸する中央アーム24を有している。 The arm portions (also referred to as a second arm portion, a handle portion, and a shaft portion) 21 and 24 have different extending directions from the distal arm 21 extending from the distal end beyond the connecting portion, and have a different holding direction. It has a central arm 24 that extends in the same direction as the straight portion 251 (see FIG. 3) that is the inner part of the hand 25.
 力点部材20の先端側アーム21が、持ち手25とは反対側の先端側の端部から、固定部材10の支持穴部15に挿入され、支点孔23と、支持穴部15の側面の小孔151A,151Bとが一致した状態で、支点孔23及び小孔151A,151Bを貫通するように、ピン軸PS2で係止される。 The distal arm 21 of the power point member 20 is inserted into the support hole 15 of the fixing member 10 from the distal end opposite to the handle 25, and the fulcrum hole 23 and the small side surface of the support hole 15 are formed. In a state where the holes 151A and 151B coincide with each other, the holes are locked by the pin shaft PS2 so as to pass through the fulcrum hole 23 and the small holes 151A and 151B.
 この係合により、ピン軸PS2を回転軸として、力点部材20が固定部材10に対して回転することができる。即ち、力点部材20は、第1種梃子の原理を用いて、持ち手25を力点、固定部材10との係合部を支点、上端部を作用点として回動する。 By this engagement, the power point member 20 can rotate with respect to the fixed member 10 about the pin axis PS2 as a rotation axis. That is, the power point member 20 rotates using the handle 25 as a power point, an engagement portion with the fixing member 10 as a fulcrum, and an upper end portion as an action point, using the first-type lever principle.
 力点部材20を固定部材10に対して回転させる際に、図3に示す固定部材10のアーム14、及び力点部材20のアーム部21,24は、応力発生範囲である。応力発生範囲には、使用の際に最も応力が大きくなる最大応力発生箇所を含んでいる。なお、応力発生範囲とは、応力が比較的大きく発生する部位であって、他の部位にも、応力は発生する。 ア ー ム When the power point member 20 is rotated with respect to the fixed member 10, the arm 14 of the fixed member 10 and the arm portions 21 and 24 of the power point member 20 shown in FIG. The stress generation range includes the maximum stress generation point where the stress is maximized in use. Note that the stress generation range is a portion where a relatively large stress is generated, and the stress is also generated in other portions.
 持ち手(ハンドル、指環、取っ手、把持部)25は、指が入る指穴が形成されてリング形状である。例えば、持ち手25の指穴には、使用者が自分で上まつ毛をカールする際、使用者の人差し指、中指、又は薬指が挿入される場合が多い。あるいは、施術者によってまつ毛をカールしてもらう際、又は自分で下まつ毛をカールする際は、施術者の親指が持ち手25に挿入される場合が多い。 The handle (handle, finger ring, handle, grip portion) 25 has a ring shape with a finger hole into which a finger enters. For example, the index finger, the middle finger, or the ring finger of the user is often inserted into the finger hole of the handle 25 when the user curls the upper eyelash by himself. Alternatively, the practitioner's thumb is often inserted into the handle 25 when the practitioner curls the eyelashes or curls the lower eyelashes by himself.
 力点部材20は、持ち手25と、延伸するアーム部21,24とが一体的に形成されており、力点部材20において、アーム部21,24は一本で形成され、持ち手25と同じ太さである。 The power point member 20 is formed integrally with a handle 25 and extending arm portions 21 and 24.

Further, the central arm 24 extends in the same direction as the straight portion 251 (see FIG. 3) which is a portion inside the handle 25. Due to the inclination of the arms 21 and 24 of the power point member 20, the straight portion 251 of the handle 25 continuously extending from the arm 24 becomes substantially parallel to the straight portion 161 of the handle 16 continuously extending from the arm 14. Therefore, the force can be applied without waste.
 また、図1、図2、図3を参照して、固定部材10において、持ち手16は、1本のアーム14の下端から厚さ方向y(図6C参照)に分岐点BP1で分岐して、アーム14から直線状に延伸する直線部161と、該直線部161の下端から第1の厚さ方向に膨らんで折り返して分岐点BPに戻る湾曲部162によって指穴を形成するように構成されている。 Also, with reference to FIGS. 1, 2, and 3, in the fixing member 10, the handle 16 branches from the lower end of one arm 14 in the thickness direction y (see FIG. 6C) at a branch point BP1. The finger hole is formed by a straight portion 161 extending linearly from the arm 14 and a curved portion 162 which bulges from the lower end of the straight portion 161 in the first thickness direction and turns back to return to the branch point BP. ing.
 また、力点部材20において、持ち手25は、1本で構成されるアーム部21,24の中央アーム24の下端から厚さ方向に分岐点BP2で分岐して、アーム部の一部である中央アーム24から直線状に延伸する直線部251と、該直線部251の下端から第1の厚さ方向とは反対方向の第2の厚さ方向に膨らんで折り返して分岐点BP2に戻る湾曲部252によって指穴を形成するように構成されている。 In the power point member 20, the handle 25 branches from the lower end of the central arm 24 of the single arm unit 21, 24 at a branch point BP <b> 2 in the thickness direction, and forms a central part of the arm unit. A straight portion 251 extending linearly from the arm 24, and a curved portion 252 which bulges from the lower end of the straight portion 251 in a second thickness direction opposite to the first thickness direction, returns and returns to the branch point BP2. Are formed to form finger holes.

 リンク部(昇降支柱)32A,32Bは、上端が下側プレス部31と連接され、略V状に傾斜して、下端が連結部33と連接している。 The link portions (elevating columns) 32A, 32B have their upper ends connected to the lower press portion 31, are inclined substantially V-shaped, and have their lower ends connected to the connecting portion 33.
 また、本実施形態では、連結部33の上端側には、リンク部32A,32Bは、係合溝部の前で合流する合流部332Jが設けられている。合流部332Jは、アイラッシュカーラー1の中で最も細いリンク部32A,32Bを補強している。 In the present embodiment, a joining portion 332J is provided on the upper end side of the connecting portion 33 so that the link portions 32A and 32B join in front of the engaging groove portion. The joining portion 332J reinforces the thinnest link portions 32A and 32B in the eyelash curler 1.
 連結部33は立体的な先端がU字(コの字)状の係合溝部形状である。そして、連結部33を形成する両側の側面には幅方向に貫通する、小孔331A,331Bが形成されている。 The connecting portion 33 has a three-dimensional U-shaped (U-shaped) engagement groove. Small holes 331A and 331B are formed on the side surfaces on both sides forming the connecting portion 33 so as to penetrate in the width direction.
 力点部材20の先端側アーム21の先端が、作用部材30の連結部33のU字の内側に挿入され、先端孔22と、連結部33の側面の小孔331A,331Bとが一致した状態で、先端孔22及び小孔331A,331Bを貫通するように、ピン軸PS1で係止される。 The distal end of the distal end arm 21 of the power point member 20 is inserted inside the U-shape of the connecting portion 33 of the action member 30, and the distal end hole 22 and the small holes 331 </ b> A and 331 </ b> B on the side surface of the connecting portion 33 are aligned. , And is locked by the pin shaft PS1 so as to pass through the distal end hole 22 and the small holes 331A and 331B.
 この係合により、ピン軸PS1を回転軸として、力点部材20が回転した際に、作用部材30は一緒に連動して上下に昇降することができる。 By this engagement, when the power point member 20 rotates about the pin axis PS1 as the rotation axis, the action member 30 can move up and down in conjunction with it.
 また、下側プレス部31の左右の両端には、一部を欠いた略円形状(フック形状)の係合フック(係合部、両端フック)311A,311Bが設けられている。係合フック311A,311Bが、一対の平行支柱12A,12Bに対して係合することで、下側プレス部31が固定部材10の平行支柱12A,12Bに沿ってスライド移動可能になる。 係 合 At the left and right ends of the lower press portion 31, engagement hooks (engagement portions, both end hooks) 311A and 311B having a substantially circular shape (hook shape) partially omitted are provided. By engaging the engaging hooks 311A and 311B with the pair of parallel columns 12A and 12B, the lower press portion 31 can slide along the parallel columns 12A and 12B of the fixing member 10.
 図3では、係合フック311A,311Bは、側方(奥行方向)に開口している例を示しているが、本実施形態では、係合フック311A,311Bは、正面視からみた後方(第2の厚さ方向)が開口していてもよい。 FIG. 3 shows an example in which the engaging hooks 311A and 311B are open to the side (in the depth direction). However, in the present embodiment, the engaging hooks 311A and 311B are located rearward (from the front). 2 (thickness direction).
 なお、下側プレス部31の上面には、弾性部材であるクリッパーゴムCR(図2参照)が挟まれる。そのため、下側プレス部31の上面には、クリッパーゴムCRを挟むための溝部312Gが形成されている。 ク リ A clipper rubber CR (see FIG. 2), which is an elastic member, is sandwiched on the upper surface of the lower press portion 31. Therefore, a groove 312G for sandwiching the clipper rubber CR is formed on the upper surface of the lower press portion 31.
 この構成により、一端側の持ち手25を持ち手16に近づけるように移動させると、力点部材20は、支点孔23及び小孔151A,151Bとの連結部であるピン軸PS2を支点(支点B)として回動することで、他端側の作用部材30との連結部33との連結する先端孔22が、持ち手25の移動とは反対の方向に移動し、作用部材30がピン軸PS1とともに、押し上げられる。 With this configuration, when the handle 25 on one end side is moved closer to the handle 16, the power point member 20 causes the pin shaft PS2, which is a connecting portion between the fulcrum hole 23 and the small holes 151A and 151B, to be supported by a fulcrum (fulcrum B). ), The distal end hole 22 connected to the connecting portion 33 with the operating member 30 at the other end moves in the direction opposite to the movement of the handle 25, and the operating member 30 is moved to the pin shaft PS1. With it, it is pushed up.
 これにより、持ち手25を移動させることで、作用部材30は、先端孔22の昇降に応じて、係合フック311A,311Bが、固定部材10の平行支柱12A,12Bに沿ってスライドしながら、下側プレス部31を昇降させる。 Thereby, by moving the handle 25, the operating member 30 causes the engaging hooks 311 </ b> A, 311 </ b> B to slide along the parallel columns 12 </ b> A, 12 </ b> B of the fixing member 10 according to the elevation of the distal end hole 22. The lower press section 31 is moved up and down.
 また、力点部材20は、固定部材10の一部を支点として回動することで、作用部材30を上下に移動させる。 力 The force member 20 moves the action member 30 up and down by rotating about a part of the fixed member 10 as a fulcrum.
 固定部材10の上側プレス部11に対して、作用部材30の下側プレス部31が接近し、クリッパーゴムCRと、上側プレス部11の間でまつ毛に圧力をかける(クランプする)ことで、まつ毛にくせを付ける。 The lower press portion 31 of the action member 30 approaches the upper press portion 11 of the fixing member 10 and applies pressure (clamps) to the lashes between the clipper rubber CR and the upper press portion 11 to make the lashes Add a habit.
 図4Aは第1実施形態のアイラッシュカーラー1の正面図であり、図4Bは、第1実施形態のアイラッシュカーラー1の背面図である。 FIG. 4A is a front view of the eyelash curler 1 of the first embodiment, and FIG. 4B is a rear view of the eyelash curler 1 of the first embodiment.
 図4A及び図4Bを参照して、力点部材20が回転する方向と直交する方向を奥行方向としたとき、固定部材10において、アーム(第1のアーム部)14の少なくとも一部と、第1の持ち手16の奥行方向における幅(x1)が等しい。また、力点部材20において、第2のアーム部21,24の少なくとも一部である中央アーム24と、第2の持ち手25の、奥行方向における幅(x1)が等しい。 Referring to FIGS. 4A and 4B, when a direction orthogonal to the direction in which force member 20 rotates is defined as a depth direction, at least a part of arm (first arm portion) 14 and first Of the handle 16 in the depth direction are equal. In the power point member 20, the width (x1) in the depth direction of the central arm 24, which is at least a part of the second arm portions 21, 24, and the second handle 25 is equal.
 図1~図4Bを参照して、第1の持ち手16の直線部161と湾曲部162と、第2の持ち手25の直線部251と湾曲部252は、奥行方向において重なっている。 ~ Referring to FIGS. 1 to 4B, the straight portion 161 and the curved portion 162 of the first handle 16 and the straight portion 251 and the curved portion 252 of the second handle 25 overlap in the depth direction.
 ここで「幅が等しい」、「重なっている」とは、完全に等しいもの、完全に重なっているものだけではなく、ある程度の誤差を含むものであって、一部分が重なっているものも含むとする。例えば、直線部251,161と湾曲部252,162とで、幅が異なっていてもよく、その場合は奥行方向において、太い方が細い方に一部分が重なっている形状となる。 Here, “equal in width” and “overlapping” mean not only completely equal and completely overlapping, but also including some degree of error, including partially overlapping. I do. For example, the width may be different between the straight portions 251 and 161 and the curved portions 252 and 162, and in such a case, in the depth direction, the thicker portion partially overlaps the thinner portion.
 また、図1~図4Bを参照して、本実施形態では、アーム14は、分岐点から持ち手16まで一本で延伸しており、持ち手16の幅(奥行)及び高さ(厚み)は、アーム14の奥行方向の幅及び厚みと、同じ太さである。 Also, with reference to FIGS. 1 to 4B, in the present embodiment, the arm 14 extends from the branch point to the handle 16 by one, and the width (depth) and height (thickness) of the handle 16 are provided. Is the same thickness as the width and thickness of the arm 14 in the depth direction.
 この構成により、同じ太さで、奥行き方向に重なっている持ち手16,25から、同じ幅で、同じ方向に延伸するアーム部14,21,24を介して、操作時に、指からの挟む力がまっすぐに加わるため、まつ毛の挟み込みの力が伝達されやすい。 With this configuration, the force of pinching by a finger at the time of operation from the handles 16 and 25 having the same thickness and overlapping in the depth direction via the arms 14, 21 and 24 extending in the same direction with the same width. Is applied straight, so that the force of pinching the eyelashes is easily transmitted.
 アイラッシュカーラー1において、固定部材10と、力点部材20と、作用部材30は、それぞれ、樹脂で一体的に構成されているが、構成する樹脂の詳細については後述する。 In the eyelash curler 1, the fixing member 10, the power point member 20, and the action member 30 are each integrally formed of a resin, but details of the constituent resins will be described later.
 なお、本実施形態において、力点部材20と作用部材30との連結部と、固定部材10と力点部材20との連結部において、それぞれの部材を連結するための連結軸であるピン軸(PS1,PS2)によって回転可能に固定されているが、ピン軸PS1,PS1を構成する素材は、樹脂や金属等、いずれの素材であってもよい。 In the present embodiment, a pin shaft (PS1, which is a connecting shaft for connecting the members at the connecting portion between the power point member 20 and the acting member 30 and at the connecting portion between the fixing member 10 and the power point member 20). Although it is rotatably fixed by PS2), the material forming the pin shafts PS1 and PS1 may be any material such as resin and metal.
 なお、ピン軸PS1,PS2を樹脂で構成すると、アイラッシュカーラー1を構成する構成要素の全てが樹脂製になり、完全金属フリーが実現できる。 When the pin shafts PS1 and PS2 are made of resin, all the constituent elements of the eyelash curler 1 are made of resin, and it is possible to realize completely metal-free.

 図5A,図5Bは、比較例の金属製のアイラッシュカーラーの図である。図5A,図5Bに示すアイラッシュカーラー9は、一般的な金属製のアイラッシュカーラーの一例である。図5Aは比較例の金属製のアイラッシュカーラー9の前面斜視図であり、図5Bは比較例の金属製のアイラッシュカーラー9の背面斜視図である。
<Comparative example>
5A and 5B are diagrams of a metal eyelash curler of a comparative example. The eyelash curler 9 shown in FIGS. 5A and 5B is an example of a general metal eyelash curler. FIG. 5A is a front perspective view of the metal eyelash curler 9 of the comparative example, and FIG. 5B is a rear perspective view of the metal eyelash curler 9 of the comparative example.
 金属製のアイラッシュカーラー9について、図1に示す本発明のアイラッシュカーラー1との構造面での相違点を下記説明する。 Regarding the metal eyelash curler 9, a difference in structure from the eyelash curler 1 of the present invention shown in FIG. 1 will be described below.
 図5A,図5Bで示す金属製のアイラッシュカーラー9では、固定部材70は、上側プレス部(金属フレーム)11と、細い金属棒とが別々に形成された後、接着される。力点部材80は、一本の細い金属棒を変形することで成形されている。作用部材90は、下側プレス部(金属フレーム)91と、細い金属棒とが別々に形成された後、接着される。 In the metal eyelash curler 9 shown in FIGS. 5A and 5B, the fixing member 70 is bonded after the upper press portion (metal frame) 11 and the thin metal bar are separately formed. The power point member 80 is formed by deforming a single thin metal bar. The operation member 90 is bonded after a lower press portion (metal frame) 91 and a thin metal bar are separately formed.
 詳しくは、固定部材70において、金属棒を加工することで、下端でリング状に捻って持ち手76を形成して、金属棒の平行支柱72A,72Bに相当する上側の両端部において、対向する部分には縦に長い切れ込み孔を形成しておく。この際、下端でリング状に捻られ、支柱部72A,73A,72B,73Bから持ち手76の手前までの、延伸部であるアーム74では、2本の細い金属棒(741,742)が接触した又は近接した状態で並んでいる。そして、金属棒である平行支柱72A,72Bの先端の内側面の切れ込み孔に金属フレームを挿入して溶着することで、上側プレス部71と平行支柱72A,72Bとが連結される。 More specifically, in the fixing member 70, by processing a metal bar, the lower end is twisted in a ring shape to form a handle 76, and opposes at both upper ends corresponding to the parallel columns 72 </ b> A and 72 </ b> B of the metal bar. A longitudinally long slit is formed in the portion. At this time, two thin metal rods (741, 742) are twisted in a ring shape at the lower end and are in contact with the arm 74, which is an extended portion, from the support portions 72A, 73A, 72B, 73B to a position short of the handle 76. Lined up or in close proximity. Then, the upper press portion 71 and the parallel columns 72A, 72B are connected by inserting and welding a metal frame into the notch holes on the inner surfaces at the tips of the parallel columns 72A, 72B, which are metal rods.
 力点部材80において、下端でリング状に捻って持ち手85を形成し、持ち手85から先端までの延伸部であるアーム部81,84では、2本の細い金属棒(811,812)、(841,842)が接触した状態で並んでいる。 In the power point member 80, a handle 85 is formed by twisting the ring at the lower end, and two thin metal rods (811, 812) and (2) in the arms 81 and 84, which are extending portions from the handle 85 to the distal end. 841, 842) are in contact with each other.
 作用部材90において、1本の金属を折り曲げて略V字形状にした金属棒の端部を、金属フレームである下側プレス部91に対して溶着することで、リンク部92A,92Bと下側プレス部91とが連結される。 In the action member 90, the ends of a metal bar formed by bending a single metal into a substantially V-shape are welded to the lower press portion 91, which is a metal frame, so that the link portions 92A and 92B and the lower side are joined. The press section 91 is connected.
 また、作用部材90において、リンク部92A,92Bの略V字状の頂点が、力点部材80と連結される際、力点部材80の先端係合孔82に、細い金属棒が挿入された状態で折れ曲げられてリンク部92A,92Bの形状となった状態で、リンク部92A,92Bの上端が下側プレス部91に溶着される。このように、作用部材90の成形と、作用部材90と力点部材80との連結が同時に行われるため、製造後は作用部材90と力点部材80とは脱着しない。 When the substantially V-shaped vertices of the link portions 92A and 92B of the action member 90 are connected to the power point member 80, the thin metal rod is inserted into the distal end engagement hole 82 of the power point member 80. The upper ends of the link portions 92A and 92B are welded to the lower press portion 91 in a state where the link portions 92A and 92B are bent and formed into the shapes of the link portions 92A and 92B. As described above, since the forming of the operating member 90 and the connection between the operating member 90 and the power point member 80 are performed at the same time, the operating member 90 and the power point member 80 are not detached after manufacturing.
 この構成では、固定部材70及び力点部材80において、リングを形成する持ち手76,85では、2本にまとめられたアーム74、(81,84)に対して1本分の細さとなるため、持ち手76,85では、断面の円柱が細く、ホールド性が悪い。 In this configuration, in the fixing member 70 and the power point member 80, the handles 76 and 85 forming the ring are thinner by one than the arms 74 and (81, 84) combined into two. In the handles 76 and 85, the column of the cross section is thin, and the holding property is poor.
 これに対して、本発明のアイラッシュカーラー1は、樹脂で構成されているため、固定部材10及び力点部材20において、アーム14,(21,24)は一本で構成され、持ち手16,25と同じ太さである。 On the other hand, since the eyelash curler 1 of the present invention is made of resin, the arm 14, (21, 24) of the fixing member 10 and the power point member 20 is made of a single arm, They are the same thickness.
 このように本発明の構成では、固定部材10及び力点部材20において、持ち手16,25の断面形状をアーム部14,21,24と同じ太さにすることで、持ち手16,25を太くすることが出来、ホールド性が向上し、力をかけても指にめり込まず、痛くならないため、十分に力をかけることができる。 As described above, in the configuration of the present invention, in the fixing member 10 and the force applying member 20, the cross-sectional shapes of the handles 16, 25 are made the same thickness as the arms 14, 21, 24, so that the handles 16, 25 are made thick. Can be performed, the hold property is improved, and even if force is applied, the finger does not sink into the finger and does not hurt, so that sufficient force can be applied.
 さらに、本発明のアイラッシュカーラー1では、図3、図4A、図4Bを参照して、第1の持ち手16の直線部161と湾曲部162と、第2の持ち手25の直線部251と湾曲部252とは、奥行方向において重なっている。 Further, in the eyelash curler 1 of the present invention, referring to FIGS. 3, 4A and 4B, the straight portion 161 and the curved portion 162 of the first handle 16 and the straight portion 251 of the second handle 25 are curved. The portion 252 overlaps in the depth direction.
 そのため、図5A,図5Bに示す金属製の構成のように直線部と湾曲部とでねじれて構成される持ち手よりも、奥行方向に重なっている持ち手の方が、力がまっすぐに掛かるため、より操作しやすく、まつ毛への力がかかりやすい。 For this reason, a handle that overlaps in the depth direction exerts a straighter force than a handle that is twisted between a straight portion and a curved portion as in the metal configuration illustrated in FIGS. 5A and 5B. Therefore, it is easier to operate, and the force on the eyelashes is easily applied.
 また、金属製のアイラッシュカーラー9では、固定部材70のアーム74は2本の金属棒741,742で構成され、この棒の間隔が傾斜支柱73A,73Bとして広がるすぐ下の挟み込み部75で、側方から、力点部材80のアーム81を挟み込み、ピン83を通すことで挟み込み部75にアーム81を係合している。そのため、挟み込み部75でアーム81を挟み込んでいる支点の部分の上側は剥き出しになっている。この構成を用いて、まつ毛カール動作の際に、力点部材80を固定部材70に対して回動させると、挟み込み部75でアーム81を挟み込んでいる支点の部分に、髪、ティッシュ、又はコットン等が、巻き込まれてしまう恐れがあった。 In the metal eyelash curler 9, the arm 74 of the fixing member 70 is composed of two metal rods 741 and 742, and the interval between the rods is widened as inclined supports 73 </ b> A and 73 </ b> B. Thus, the arm 81 of the power point member 80 is sandwiched, and the arm 81 is engaged with the sandwiching portion 75 by passing the pin 83. Therefore, the upper side of the fulcrum where the arm 81 is sandwiched by the sandwiching portion 75 is exposed. Using this configuration, when the power point member 80 is rotated with respect to the fixing member 70 during the eyelash curling operation, hair, tissue, cotton, or the like is applied to the fulcrum where the arm 81 is sandwiched by the sandwiching portion 75. However, there was a risk of getting caught.
 これに対して、本発明は、固定部材10において、力点部材20が挿通する支持穴部15の上側のアーム21の上端には、合流部141Jが存在しているため、固定部材10に対して回動する力点部材20の支点の上側は剥き出しになっていない。そのため、近くに髪等が存在しても、力点部材20と固定部材10との係合部に挟み込まれる可能性が低い。 On the other hand, according to the present invention, in the fixing member 10, the joining portion 141J exists at the upper end of the arm 21 above the support hole 15 through which the power point member 20 is inserted. The upper side of the fulcrum of the rotating force point member 20 is not exposed. Therefore, even if hair or the like exists nearby, the possibility of being pinched by the engaging portion between the power point member 20 and the fixing member 10 is low.
 <構成近似>
 アイラッシュカーラーは複雑な形状であるので、単純な形状に置き換えて形状算出を行った。
<Structure approximation>
Since the eyelash curler has a complicated shape, the shape was calculated by replacing it with a simple shape.
 図6A,図6B,図6Cは、アイラッシュカーラーにおける力の掛かり方を近似して説明する図である。図6Aはアイラッシュカーラーにおける支点及び荷重点の位置を示す図、図6Bは、図6Aの支点及び荷重点をはねだし単純梁(片側集中荷重)に近似した図である。図6Cは、固定部材及び力点部材の梁部の断面図であって、図6AのD断面に相当する。 FIGS. 6A, 6B, and 6C are diagrams for explaining how a force is applied in the eyelash curler by approximation. FIG. 6A is a diagram showing the positions of the fulcrum and the load point in the eyelash curler, and FIG. 6B is a diagram in which the fulcrum and the load point in FIG. 6A are projected and approximated to a simple beam (one-side concentrated load). FIG. 6C is a cross-sectional view of a beam portion of the fixing member and the power point member, and corresponds to a D section of FIG. 6A.
 まつ毛を挟んだ瞬間はアイラッシュカーラーの回転部である力点部材20は回転を規制され、殆ど回転及び移動がないものと考えることが出来るため、図6Aに示すアイラッシュカーラーの連結部は、図6Bの支点A,Bに置き換えることが出来る。 At the moment when the eyelashes are pinched, the power point member 20, which is the rotating part of the eyelash curler, is restricted from rotating, and it can be considered that there is almost no rotation and movement. Therefore, the connecting part of the eyelash curler shown in FIG. , B.
 荷重点Cは力点部材20の持ち手25とし、荷重Pは指からアイラッシュカーラーに加えられる力(グリップ力)とする。 The load point C is the handle 25 of the power point member 20, and the load P is the force (grip force) applied from the finger to the eyelash curler.
 ここで、固定部材10及び力点部材20が、はねだし単純梁の「梁」として機能し、荷重や作用について考慮する際、図6Cに示すように、力を受ける部分である固定部材10及び力点部材20から成る梁の断面の幅(奥行)(x)及び高さ(厚み)(y)が考慮される。 Here, the fixing member 10 and the force-point member 20 function as “beams” of the projecting simple beam, and when considering the load and the action, as shown in FIG. The width (depth) (x) and height (thickness) (y) of the cross section of the beam composed of the power point member 20 are considered.
 なお、説明において、図6Aに示すように、力点部材20が回動する方向を回転方向、回転方向と直交する方向を奥行方向とする。また、図6Cに示すように、固定部材10および力点部材20の断面において奥行方向と直交する方向を厚さ方向とする。 In the description, as shown in FIG. 6A, the direction in which the force applying member 20 rotates is referred to as a rotation direction, and the direction orthogonal to the rotation direction is referred to as a depth direction. In addition, as shown in FIG. 6C, a direction perpendicular to the depth direction in the cross section of the fixing member 10 and the power point member 20 is defined as a thickness direction.
 図6Cに示すように、力が直接付加される、固定部材10のアーム14及び持ち手16、力点部材20のアーム部21,24及び持ち手25の断面は、円形の金属製の厚みを変えずに、断面積を増やしてより強い強度を得るために、四角形、又は角丸四角形であると好適である。しかし、図6Cに示す、断面が四角形の梁の構成は一例であって、固定部材10及び力点部材20の梁の断面形状は、図6Cに示す矩形に限られず、成形性や触感等を重視して、円形や、楕円形、半円形などの他の形状であってもよい。 As shown in FIG. 6C, the cross section of the arm 14 and the handle 16 of the fixing member 10 and the arms 21, 24 and the handle 25 of the force-point member 20 to which a force is directly applied changes the thickness of the circular metal. Instead, in order to increase the cross-sectional area and obtain stronger strength, it is preferable that the shape be a square or a rounded square. However, the configuration of the beam having a quadrangular cross section shown in FIG. 6C is an example, and the cross sectional shape of the beam of the fixing member 10 and the power point member 20 is not limited to the rectangular shape shown in FIG. Alternatively, the shape may be another shape such as a circle, an ellipse, and a semicircle.
 また、図6Bに示した、「はねだし単純梁(片側集中荷重)」の構造では支点B周辺に発生する曲げモーメントMBが最大となる。 で は In addition, in the structure of “spring-out simple beam (single-side concentrated load)” shown in FIG. 6B, the bending moment MB generated around the fulcrum B is the maximum.
 そこで、本発明者は、物体であるアイラッシュカーラーに外力(荷重P)が加わる場合を、金属製の既存のアイラッシュカーラーを基にした、シミュレーションにより、評価を行い、樹脂の選定を行った。その結果を、後述の図8Aに示す。 Therefore, the present inventor evaluated the case where an external force (load P) was applied to the eyelash curler as an object by simulation based on the existing metal eyelash curler, and selected a resin. The result is shown in FIG. 8A described later.
 図7A,図7Bは、力点部材における寸法の比率を示す図である。詳しくは、図7Aは、力点部材での力の比率と可動角度を考慮した本発明のアイラッシュカーラー1の構成例を示す図であり、図7Bは、力点部材での力の比率を考慮したアイラッシュカーラーの構成例を示す図である。 FIGS. 7A and 7B are diagrams showing the ratio of the dimensions of the power point member. More specifically, FIG. 7A is a diagram illustrating a configuration example of the eyelash curler 1 of the present invention in which the force ratio and the movable angle of the power point member are considered, and FIG. 7B is a diagram of the eyelash curler in which the force ratio of the power point member is considered. It is a figure showing the example of composition.
 上記のはねだし単純梁(片側集中荷重)」の構造をアイラッシュカーラーに適用する際、力点部材において、一般的に下記の点が知られている。 When applying the above structure of “spring out simple beam (single-side concentrated load)” to an eyelash curler, the following points are generally known in a power point member.
 アイラッシュカーラー1は、第1種梃子の原理により、力点部材20を回動させて、持ち手25を力点として、作用部材30に作用させることで、カール動作を行っている。そのため、支点と作用点までの距離よりも、力点と作用点までの距離が遠い方が、より軽い力でまつ毛カール動作が実現できる。そのため、図7A,図7Bに示す、距離a<距離bのように設計することはよく知られている。 The eyelash curler 1 performs a curling operation by rotating the power point member 20 and acting on the action member 30 with the handle 25 as the power point according to the principle of the first type lever. Therefore, when the distance between the power point and the action point is farther than the distance between the fulcrum and the action point, the eyelash curling operation can be realized with a lighter force. Therefore, it is well known to design the distance a <the distance b shown in FIGS. 7A and 7B.
 また、力点部材20における、支点Bから先端側までの区間の距離a、支点Bから持ち手側までの区間の距離bの寸法は、梃子の原理でクランプ圧(まつ毛を挟み込む圧力)に影響を及ぼす点を考慮して、a:b=1:3以上であると好適である。即ち、力点部材20において、支点から力点部材20の下端までの距離を、上端から支点までの距離の3倍以上に設定する。本実施形態では、力点部材20において、ピン軸PS2によって固定部材10と係合する支点である支点孔23から力点部材20の下端までの距離を、ピン軸PS1によって作用部材30と係合する先端孔22から支点孔23までの距離の3倍以上に設定する。 The dimension of the distance a between the fulcrum B and the tip side and the distance b between the fulcrum B and the handle side of the power point member 20 influences the clamping pressure (pressure for pinching the eyelashes) by the principle of leverage. In consideration of the effect, it is preferable that a: b = 1: 3 or more. That is, in the power point member 20, the distance from the fulcrum to the lower end of the power point member 20 is set to be three times or more the distance from the upper end to the fulcrum. In the present embodiment, the distance from the fulcrum hole 23, which is the fulcrum engaged with the fixing member 10 by the pin axis PS2, to the lower end of the power point member 20 in the power point member 20, is determined by the tip that engages with the action member 30 by the pin axis PS1. The distance from the hole 22 to the fulcrum hole 23 is set to three times or more.
 しかし、携帯性を考慮すれば小型な方が望ましいが、単に比率を設定しただけでは、例えば、図7Bのように、力点部材及び固定部材が短い構成も含まれる。このように力点部材20が短い構造だと、支点Bに対して、力点及び作用点のどちらも近いため、持ち手に対してかなり大きな力を掛ける必要があるとともに、支点Bにおける可動角度を大きく設定する必要がある。 However, it is desirable to have a small size in consideration of portability, but simply setting the ratio also includes a configuration in which the power point member and the fixing member are short as shown in FIG. 7B, for example. When the power point member 20 has such a short structure, since both the power point and the action point are close to the fulcrum B, it is necessary to apply a considerably large force to the handle and increase the movable angle at the fulcrum B. Must be set.
 そこで、本仕様において、力点(荷重点)である持ち手25の直線部251(図6A参照)を、指穴側から押す際の使用感とカールするだけのクランプ圧が発生するバランスを意識した値として、下側プレス部31の移動量を4mm以上確保する場合、可動角度や、力のかけ方を考慮して、a=10mm以上であると好適である。即ち、第1実施形態では、力点部材20において、上端から支点Bまでの距離である上端である先端孔22から、支点Bの位置にある支点孔23までの距離を10mm以上に設定すると好適である。 Therefore, in this specification, the balance between the usability when pressing the straight portion 251 of the handle 25 (see FIG. 6A), which is the power point (load point), from the finger hole side and the clamp pressure sufficient to curl is generated. As a value, when the moving amount of the lower press portion 31 is to be 4 mm or more, it is preferable that a = 10 mm or more in consideration of a movable angle and a method of applying force. That is, in the first embodiment, in the power point member 20, it is preferable that the distance from the tip end hole 22 which is the upper end which is the distance from the upper end to the fulcrum B to the fulcrum hole 23 at the fulcrum B is set to 10 mm or more. is there.
 <素材の選定>
 図8Aは複数の素材で、アイラッシュカーラーを形成して使用した際の評価結果であり、図8Bは、ヤング率と断面係数に基づく実施可能範囲を示す図である。
<Selection of material>
FIG. 8A is an evaluation result when an eyelash curler is formed from a plurality of materials and used, and FIG. 8B is a diagram illustrating a feasible range based on a Young's modulus and a section modulus.
 詳しくは、図8Aは、所定の断面積と断面係数を有する素材であるSUS304(ステンレス)、ナイロン6/10、ポリアミド(PA)、PAにガラスファイバー(GF)を55%加えた繊維強化樹脂、ポリエーテルエーテルケトン(PEEK)、ポリブチレンテレフタレート(PBT)、GFポリアミドMXD6、CFポリアミドMXD6について、図7Aを満たす寸法を有するアイラッシュカーラーを形成して使用した際の、評価結果である。 More specifically, FIG. 8A shows SUS304 (stainless steel), nylon 6/10, polyamide (PA), a material having a predetermined cross-sectional area and a cross-sectional modulus, a fiber-reinforced resin obtained by adding 55% of glass fiber (GF) to PA, It is an evaluation result when an eyelash curler having a dimension satisfying FIG. 7A is formed and used for polyetheretherketone (PEEK), polybutylene terephthalate (PBT), GF polyamide MXD6, and CF polyamide MXD6.
 なお、繊維強化樹脂である「PA+GF55%」については、断面積を変化させることで、断面係数を変えて強度評価を行った。断面積を大きくすることで、断面係数が上がり、図8Bのグラフ上の位置が上方向に移動することになり、同じ素材であっても評価が良くなることがある。例えば、「PA+GF55%」の素材で、断面係数が4.5(mm3)の場合は、強度を満たさず、総合判定は「×」であったが、断面係数が15.05(mm3)の場合、及び断面係数が36(mm3)の場合、強度を満たし、総合判定は「〇」になった。 In addition, about "PA + GF55%" which is a fiber reinforced resin, the cross-sectional area was changed and the cross-sectional coefficient was changed, and the strength was evaluated. By increasing the cross-sectional area, the cross-sectional modulus increases, and the position on the graph of FIG. 8B moves upward, and the evaluation may be improved even with the same material. For example, in the case of a material of “PA + GF55%”, when the section modulus is 4.5 (mm 3 ), the strength is not satisfied, and the overall judgment is “×”, but when the section modulus is 15.05 (mm 3 ), and When the section modulus was 36 (mm 3 ), the strength was satisfied, and the overall judgment was “〇”.
 また、PBTについては、断面積を「PA+GF55%」と同様に大きくしても(断面係数=32(mm3)にしても)、強度評価を満たさず、総合判定は「〇」にならなかった。 Regarding PBT, even if the cross-sectional area was increased similarly to “PA + GF 55%” (even if the cross-sectional modulus was 32 (mm 3 )), the strength evaluation was not satisfied, and the overall judgment did not become “Δ”. .
 図8Bにおいて、四角で囲んだ部分はシミュレーションにより設定した推奨範囲である。この推奨範囲は、ヤング率が2500~40000(N/mm2)の素材で、断面係数5~40(mm3)とした。 In FIG. 8B, a portion surrounded by a square is a recommended range set by a simulation. The recommended range is a material having a Young's modulus of 2500 to 40000 (N / mm 2 ) and a section modulus of 5 to 40 (mm 3 ).
 なお、この範囲において、樹脂のヤング率が大きいほど、断面係数を小さくできる。即ち、樹脂のヤング率が大きいほど、金属製のものに近づけるように細くしても、強度を確保することができる。使用者の操作性を考慮すると、断面係数は30(mm3)以下が好ましく、断面係数は20(mm3)以下であるとさらに好ましい。 In this range, the section modulus can be reduced as the Young's modulus of the resin increases. That is, as the Young's modulus of the resin increases, the strength can be ensured even if the resin is made thinner so as to be closer to a metallic one. In consideration of the operability of the user, the section modulus is preferably 30 (mm 3 ) or less, and more preferably 20 (mm 3 ) or less.
 逆に、ヤング率が小さく弱い樹脂であっても、断面係数を大きくすれば、シミュレーションにより強度は満たす可能性があるが、操作性を考慮して、断面積を大きくし過ぎないように、断面係数の上限値を40(mm3)に設定した。 Conversely, if the resin has a low Young's modulus and is weak, if the section modulus is increased, the strength may be satisfied by simulation.However, in consideration of the operability, the cross section should not be too large. The upper limit of the coefficient was set to 40 (mm 3 ).
 そこで、断面積を大きくせずに、樹脂を含んだ素材の強度を上げるためには、アイラッシュカーラーを構成する素材は、樹脂に、ガラス繊維(GF)を配合した繊維強化樹脂によって形成すると好適である。例えば、同じ断面係数を有する樹脂にガラス繊維を加えると、ヤング率が大きくなり、図8Bのグラフ上の位置が右方向に移動することになる。 Therefore, in order to increase the strength of the material containing the resin without increasing the cross-sectional area, it is preferable that the material constituting the eyelash curler is formed of a fiber-reinforced resin in which glass fiber (GF) is mixed with the resin. . For example, when glass fibers are added to resins having the same section modulus, the Young's modulus increases, and the position on the graph of FIG. 8B moves to the right.
 また、ガラス繊維に加えて、あるいはガラス繊維に代えて、CF(カーボンファイバー)を混合してもよい。例えば、繊維強化樹脂では、ガラス繊維(GF)又はカーボン繊維(CF)を、30質量%以上、65質量%以下、配合すると好適である。 CFFurthermore, CF (carbon fiber) may be mixed in addition to or instead of glass fiber. For example, in the case of a fiber-reinforced resin, it is preferable to mix 30% by mass or more and 65% by mass or less of glass fiber (GF) or carbon fiber (CF).
 このGFやCFの添加により、樹脂材料そのもの(例えば、PA)が持つ変形や破断に対して、剛性を強化することができる。例えば、一般的なヤング率の数値は、PA:1200~2900Mpa等であるが、ガラス繊維を添加することで、ヤング率を上昇させる(例えば、4725Mpaにする)ことができる。また、この添加により、樹脂材料そのもの(例えば、PA)が持つ変形や破断に対する抵抗力を示す引っ張り強さに対して、構造解析計算上の発生応力を、30%程度に抑えられるような形状になる。よって、強化樹脂で形成したアイラッシュカーラーについて、金属製のアイラッシュカーラーのまつ毛を挟む圧力に近づけることができる。 剛性 By the addition of GF or CF, the rigidity of the resin material itself (for example, PA) against deformation and breakage of the resin material itself can be enhanced. For example, a typical value of the Young's modulus is PA: 1200 to 2900 Mpa, but the Young's modulus can be increased (for example, to 4725 Mpa) by adding glass fiber. In addition, by this addition, the resin material itself (for example, PA) is formed into a shape capable of suppressing the generated stress in structural analysis calculation to about 30% of the tensile strength indicating resistance to deformation and breakage. Become. Therefore, it is possible to make the eyelash curler formed of the reinforced resin close to the pressure for pinching the eyelashes of the metal eyelash curler.
 ガラス繊維と混合される樹脂は、ファイバーが配合可能な樹脂であれば特に制限はない。例えば、樹脂の例として、ポリアミド(PA)(様々なナイロンを含む)、ポリエーテルエーテルケトン(PEEK)、ポリエチレンテレフタレート(PETG)、グリコール変性PET(PETG)、ポリフェニレンサルファイド(PPS)、ポリアミドMXD6等である。 樹脂 The resin mixed with the glass fiber is not particularly limited as long as the resin can be mixed with the fiber. For example, examples of the resin include polyamide (PA) (including various nylons), polyetheretherketone (PEEK), polyethylene terephthalate (PETG), glycol-modified PET (PETG), polyphenylene sulfide (PPS), polyamide MXD6, and the like. is there.
 ここで、ポリアミドMXD6は、メタキシリレンジアミン(MXDA)とアジピン酸とから得られる結晶性の熱可塑性ポリマーである。ここで使用したGFポリアミドMXD6は、ポリアミドMXD6にガラス繊維(GF)が50%配合された、市販のReny(登録商標)1022Hを用いた。CFポリアミドMXD6は、ポリアミドMXD6にカーボン繊維(CF)が40%配合された市販のRenyC408を用いた。 ポ リ ア ミ ド Here, polyamide MXD6 is a crystalline thermoplastic polymer obtained from meta-xylylenediamine (MXDA) and adipic acid. As the GF polyamide MXD6 used here, a commercially available Reny (registered trademark) 1022H obtained by mixing 50% of glass fiber (GF) with polyamide MXD6 was used. As the CF polyamide MXD6, a commercially available RenyC408 obtained by mixing 40% of carbon fibers (CF) with polyamide MXD6 was used.
 なお、樹脂単体で強い強度を有するもの、例えば特殊なポリアミドMXD6の単体などにおいて、ガラス繊維やカーボンで強化しなくても、5000(N/mm2)以上のヤング率を有している場合、シミュレーションにより強度が補償できれば、断面係数5~40(mm3)の範囲のいずれの太さでも、本発明のアイラッシュカーラーの素材として採用可能である。 In the case where the resin alone has a strong strength, for example, a special polyamide MXD6 alone and has a Young's modulus of 5000 (N / mm 2 ) or more without being reinforced with glass fiber or carbon, If the strength can be compensated for by simulation, any thickness in the range of the section modulus of 5 to 40 (mm 3 ) can be adopted as the material for the eyelash curler of the present invention.
 また、特殊な樹脂でなくても、樹脂のヤング率が2500(N/mm2)以上であれば、ナイロン6/10、PEEK、PET、PETG、PPSなどであっても、上記推奨範囲内において断面係数を大きく設定することで、ガラス繊維を混合せずに、単体でアイラッシュカーラーを形成することができる。この場合、ナイロン6/10以外のこれらの樹脂単体では、ヤング率が2500(N/mm2)~5000(N/mm2)程度であると見込まれるため、成形において断面係数を、上記推奨範囲の下端から少し離れた、例えば10(mm3)以上に設定すれば、樹脂単体でも、所定の強度を実現可能であり、本発明のアイラッシュカーラーの素材として採用することができる。 Even if it is not a special resin, if the Young's modulus of the resin is 2500 (N / mm 2 ) or more, even if it is nylon 6/10, PEEK, PET, PETG, PPS, etc., it is within the above recommended range. By setting a large section modulus, an eyelash curler can be formed by itself without mixing glass fibers. In this case, it is expected that the Young's modulus of the resin alone other than nylon 6/10 is about 2500 (N / mm 2 ) to 5000 (N / mm 2 ). If it is set slightly away from the lower end, for example, at least 10 (mm 3 ), a predetermined strength can be realized even with a single resin, and it can be used as a material for the eyelash curler of the present invention.
 ここで、使用者の指の力が直接かかる固定部材10及び力点部材20の応力発生範囲であるアーム部14,21,24については、上記推奨範囲内の2500N/mm3~40000N/mm3のヤング率及び5mm3~40mm3の断面係数を満たすことが好ましい。 Here, the force of the user's fingers for arm 14,21,24 is stress generation range of the fixing member 10 and the force point member 20 such direct, of 2500N / mm 3 ~ 40000N / mm 3 in the recommended range It is preferable to satisfy Young's modulus and a section modulus of 5 mm 3 to 40 mm 3 .
 なお、間接的に力がかかり昇降動作を行う作用部材30のリンク部32A,32Bについて素材について上記推奨範囲のヤング率を満たせば、太さを規定する断面係数は推奨範囲よりも小さくてもよい。 In addition, if the materials of the link portions 32A and 32B of the action member 30 that indirectly apply a force and perform the elevating operation satisfy the Young's modulus in the above-mentioned recommended range, the section modulus defining the thickness may be smaller than the recommended range. .
 <部分用アイラッシュカーラー>
 上記実施形態では、目の幅全域に近い、まつ毛全体を挟む、全域タイプのアイラッシュカーラーを前提として説明したが、本発明の上記素材及び断面形状を有するアイラッシュカーラーは、部分用のアイラッシュカーラーであってもよい。
<Partial eyelash curler>
In the above embodiment, the eyelash curler of the whole area type, which is close to the entire width of the eyes, sandwiches the entire eyelashes, has been described, but the eyelash curler of the present invention having the above-described material and cross-sectional shape may be an eyelash curler for a part. .
 図9は、本発明の第1実施形態の変形例の部分用アイラッシュカーラーの構成図である。 FIG. 9 is a configuration diagram of a partial eyelash curler according to a modification of the first embodiment of the present invention.
 部分用アイラッシュカーラー2は、図9に示すように、上述の第1実施形態と類似する構成であって、まつ毛を挟む上側プレス部11P及び下側プレス部31Pの奥行方向の幅が短い。そのため、固定部材10Pの支柱部12C,13C,12D,13Dの間隔及び、作用部材30Pのリンク部32C,32Dの間隔も、第1実施形態よりも狭い。 As shown in FIG. 9, the partial eyelash curler 2 has a configuration similar to that of the above-described first embodiment, and the width of the upper press portion 11P and the lower press portion 31P sandwiching the eyelashes in the depth direction is short. Therefore, the interval between the support portions 12C, 13C, 12D, and 13D of the fixing member 10P and the interval between the link portions 32C and 32D of the operation member 30P are also narrower than in the first embodiment.
 短い幅の上側プレス部11Pと下側プレス部31Pとの間に挟んでまつ毛を部分的にカールさせるために必要な力は、目の幅全域の幅でまつ毛をカールさせるために必要な力よりも小さい。 The force required to partially curl the lashes between the short width upper press portion 11P and the lower press portion 31P is greater than the force required to curl the lashes across the width of the eye. Is also small.
 そのため、図9で示すように、力点部材20Pの回転の可動域が狭くなるように、力をかけない状態における持ち手16と持ち手25も幅が狭く、設定されている。 Therefore, as shown in FIG. 9, the handle 16 and the handle 25 in a state where no force is applied are also set to have a small width so that the movable range of the rotation of the power point member 20P is reduced.
 本構成においても、図8Bに示すヤング率及び断面係数の推奨範囲内の樹脂を用いて形成することで、強度を担保して、一般的な金属製の形状よりも大型化することなく、金属製と同様の操作によって、まつ毛をカールすることができる。 Also in this configuration, by using a resin within the recommended range of the Young's modulus and the section modulus shown in FIG. 8B, the strength is ensured, and the metal is not increased in size than a general metal shape. The lashes can be curled by the same operation as that for the eyelashes.
 さらに、図9に示す部分用アイラッシュカーラー2では全域タイプよりも必要な力が小さいため、素材について上記推奨範囲のヤング率を満たせば、太さを規定する断面係数は推奨範囲よりも小さくてもよい。 Further, in the partial eyelash curler 2 shown in FIG. 9, since the required force is smaller than that of the whole-area type, if the material satisfies the Young's modulus in the above-mentioned recommended range, the section modulus defining the thickness may be smaller than the recommended range. .
 また、本構成でも、固定部材10Pにおいて、係合部の上側のアームの上端には、傾斜支柱13C,13Dと合流する合流部141Jが存在しているため、髪等が存在しても、力点部材と固定部材との係合部分に挟み込まれることを予防できる。 Also in the present configuration, in the fixing member 10P, at the upper end of the upper arm of the engaging portion, the merging portion 141J merging with the inclined columns 13C and 13D is present. It is possible to prevent the member from being caught in the engaging portion between the member and the fixing member.
 さらに、本構成においても、持ち手16,25の直線部と湾曲部とで、奥行方向に重なっているため、力がまっすぐに掛かり、より操作しやすく、まつ毛への力が加わりやすい。 Further, also in this configuration, since the straight portions and the curved portions of the handles 16, 25 overlap in the depth direction, the force is applied straight, the operation is easier, and the force on the eyelashes is easily applied.

<Second embodiment>
FIG. 10 is an overall perspective view of an eyelash curler 3 according to a second embodiment of the present invention. FIG. 11 is an overall perspective view of the eyelash curler 3 of the second embodiment viewed from an angle different from FIG. FIG. 12 is an exploded view of the eyelash curler 3 of the second embodiment.
 本実施形態では、素材等は、第1実施形態で用いた樹脂と同じであるが、固定部材と力点部材との係合(支点)、及びの力点部材と作用部材との係合(作用点)のヒンジ構成等が異なる。 In the present embodiment, the material and the like are the same as the resin used in the first embodiment, but the engagement (fulcrum) between the fixing member and the power point member, and the engagement between the power point member and the action member (action point). 3) is different in the hinge configuration and the like.
 図12に示すように、本実施形態では、力点部材50において、先端部から少し離れた部分に、ヒンジ下側が凹んだ嵌合用の溝(窪み)である嵌合溝53が形成されている。 As shown in FIG. 12, in the present embodiment, a fitting groove 53 which is a fitting groove (dent) in which the lower side of the hinge is recessed is formed in the power point member 50 at a portion slightly away from the distal end.
 図12に示すように、固定部材40において、アーム44に形成された支持穴部45には、幅方向(奥行方向)に延伸する嵌合用の支点軸48が設けられている。 As shown in FIG. 12, in the fixing member 40, the supporting hole 45 formed in the arm 44 is provided with a fulcrum shaft 48 for fitting extending in the width direction (depth direction).
 そして、力点部材50の先端側アーム51が、上端側から、固定部材40の支持穴部45に挿入された状態で、力点部材50を固定部材40に対して上から下に押し込み、支持穴部45内で、嵌合溝53が支点軸48に係合することで、力点部材50と固定部材40とを連結させる。 Then, with the distal end arm 51 of the power point member 50 inserted into the support hole 45 of the fixing member 40 from the upper end side, the power point member 50 is pushed downward from above with respect to the fixing member 40, and The fitting groove 53 engages with the fulcrum shaft 48 in the connection point 45, thereby connecting the power point member 50 and the fixed member 40.
 力点部材50の嵌合溝53に嵌合された、固定部材40の支点軸48が第2の支点(図6Aの支点B)となることで、力点部材50が固定部材40に対して回動自在に連結される。 When the fulcrum shaft 48 of the fixing member 40 fitted in the fitting groove 53 of the power point member 50 becomes the second fulcrum (the fulcrum B in FIG. 6A), the power point member 50 rotates with respect to the fixing member 40. Freely connected.
 なお、図12においては、支点軸48は支持穴部45の幅方向全域に延伸している例を示しているが、嵌合溝53と嵌合可能な支点軸48は、支持穴部45の内側面から突出して中央部が途切れている、両側突起形状であってもよい。 FIG. 12 shows an example in which the fulcrum shaft 48 extends in the entire width direction of the support hole 45. However, the fulcrum shaft 48 that can be fitted in the fitting groove 53 is It may have a double-sided projection shape that protrudes from the inner side surface and has a broken central portion.
 また、アーム44は、支持穴部45の上方にも存在しており、支持穴部15の上方は、傾斜支柱43A、43Bと合流する合流部441Jが存在する。そのため、支点が剥き出しになっておらず、近くに髪、ティッシュ、コットン等が存在しても、力点部材50と固定部材40との係合部に挟み込まれることを予防できる。 The arm 44 also exists above the support hole 45, and above the support hole 15, there is a junction 441J that merges with the inclined columns 43A and 43B. Therefore, even if the fulcrum is not exposed and hair, tissue, cotton, or the like is present nearby, it is possible to prevent the fulcrum from being caught in the engaging portion between the power point member 50 and the fixing member 40.
 また、作用部材60は、下側プレス部61と、一端が該下側プレス部61と連結するリンク部62A,62Bが設けられている。 作用 The operating member 60 is provided with a lower press portion 61 and link portions 62A and 62B having one end connected to the lower press portion 61.
 また、下側プレス部61の左右の両端には、一部を欠いた略円形状(フック形状)の係合フック(係合部)611A,611Bが設けられている。本実施形態では、組立ての際の作用部材60の固定部材40への着脱を容易にするため、係合フック611A,611Bは後方が開口している。係合フック(後方フック)611A,611Bが、一対の平行支柱42A,42Bに対して係合することで、作用部材60が、固定部材40の平行支柱42A,42Bに沿ってスライド移動可能になる。 略 At the left and right ends of the lower press portion 61, substantially circular (hook-shaped) engagement hooks (engagement portions) 611A and 611B are provided. In the present embodiment, the engaging hooks 611A and 611B are open rearward to facilitate attachment and detachment of the operating member 60 to and from the fixing member 40 during assembly. By engaging the engagement hooks (rear hooks) 611A and 611B with the pair of parallel struts 42A and 42B, the operation member 60 can slide along the parallel struts 42A and 42B of the fixed member 40. .
 本構成では、リンク部62A,62Bの他端がU字状に折れ曲がって一体的に形成されており、他端におけるリンク部62A,62Bの他端同士を連結する部が、筒状の嵌合筒63である。嵌合筒63は、作用部材60の係合部である。 In this configuration, the other ends of the link portions 62A and 62B are bent in a U-shape to be integrally formed, and a portion that connects the other ends of the link portions 62A and 62B at the other end is a cylindrical fitting. It is a tube 63. The fitting tube 63 is an engaging portion of the operation member 60.
 力点部材50の先端には、上側が凹んだ嵌合用フック52が形成されている。 嵌合 At the tip of the force point member 50, a fitting hook 52 having a concave upper side is formed.
 そして、力点部材50を、作用部材60に対して下から上に押し込むこと、嵌合用フック52が嵌合筒63に係合し、力点部材50と作用部材60とを連結させる。このように、力点部材50の嵌合用フック52と、作用部材60の嵌合筒と63が嵌合することで、作用部材60が、力点部材50の作用点と連動して移動可能になる。 Then, the force point member 50 is pushed into the action member 60 from below, and the fitting hook 52 is engaged with the fitting cylinder 63 to connect the force point member 50 and the action member 60. In this manner, the fitting hook 52 of the power point member 50 and the fitting tube 63 of the operating member 60 are fitted, so that the operating member 60 can move in conjunction with the operating point of the power point member 50.
 このように、固定部材40と力点部材50との連結(図6Aの第2の支点B)、及び力点部材50と作用部材60との連結(図6Aの第1の支点A)を、フック形状で実現することで、連結のために構成要素を貫通させる軸部を用いることなく、取り付け、取り外し等をすることが出来る。 As described above, the connection between the fixing member 40 and the power point member 50 (the second fulcrum B in FIG. 6A) and the connection between the power point member 50 and the operating member 60 (the first fulcrum A in FIG. By doing so, attachment and detachment can be performed without using a shaft portion that penetrates components for connection.
 そのため、第1実施形態における、各部材同士を連結するための、金属製のピン軸PS1,PS2を用いることなく、構成要素同士の係合部の完全金属フリーが実現できる。 Therefore, in the first embodiment, it is possible to realize a completely metal-free engagement portion between the components without using the metal pin shafts PS1 and PS2 for connecting the members.
 また、フックが抜ける方向に力をかけることで、係合状態を解除できるため、使用者の手により、分解、組立てが実現できる。例えば、アイラッシュカーラー3が汚れてしまった場合に、分解洗浄が可能になることで、係合部の小さな凹凸まで洗浄することができ、その後、組み立てることができるため、細部まで清潔さを保つことができる。 係 合 Furthermore, since the engaged state can be released by applying a force in the direction in which the hook comes off, disassembly and assembly can be realized by the user's hand. For example, when the eyelash curler 3 is contaminated, it is possible to disassemble and clean, so that it is possible to clean even small irregularities of the engaging portion, and then it is possible to assemble, so that it is possible to keep cleanness in detail. it can.
 また、化粧ポーチや荷物の中で、急激に負荷がかかった場合でも、フックが外れることで破壊が回避できる。この際、第1の支点A(図6A参照)と第2の支点Bでは係合の向きが反対方向であるため、一方向に強い力が掛かった場合、第1の支点A、第2の支点Bのどちらかのみの係合状態が外れるため、不意に係合状態が脱着した場合は、簡単に復活させることができる。 Also, even if the load is suddenly applied in the makeup pouch or luggage, the hook can be released to prevent destruction. At this time, the first fulcrum A (see FIG. 6A) and the second fulcrum B are in opposite directions of engagement, so that when a strong force is applied in one direction, the first fulcrum A and the second fulcrum A Since the engagement state of only one of the fulcrums B is released, if the engagement state is suddenly detached, it can be easily restored.
 また、力点部材50の、先端側アーム51の先端には、上側が凹んだ嵌合用フック52が設けられ、先端側アーム51の持ち手55より先端部に近い部分に、下側が凹んだ嵌合溝53が形成され、アーム部(第2のアーム部)51,54は、先端から持ち手55まで一本で延伸している。 Further, a fitting hook 52 having a concave upper side is provided at the distal end of the distal end arm 51 of the power point member 50, and a fitting with a concave lower side is provided at a portion closer to the distal end of the handle 55 of the distal end arm 51. A groove 53 is formed, and the arm portions (second arm portions) 51 and 54 extend from the tip to the handle 55 by a single piece.
 そのため、本実施形態のアイラッシュカーラー3においても、第1実施形態同様に、金属製と異なり、持ち手46,55の部分を、延伸部(アーム部44、51,54)と同じ太さに太くすることができるため、金属製よりもホールド性を向上させることができる。 Therefore, also in the eyelash curler 3 of the present embodiment, similarly to the first embodiment, unlike the case of the metal, the portions of the handles 46 and 55 are thickened to the same thickness as the extending portions ( arm portions 44, 51 and 54). Therefore, the holdability can be improved as compared with the case of metal.
 ここで、図6Aの比率を満たすように、本実施形態では、力点部材20において、固定部材40と係合する支点である嵌合溝53から力点部材50の下端までの距離を、上端である作用部材60と係合する嵌合用フック52から嵌合溝53までの距離の3倍以上に設定する。 Here, in the present embodiment, the distance from the fitting groove 53, which is a fulcrum, which engages with the fixing member 40, to the lower end of the power point member 50 is the upper end so as to satisfy the ratio of FIG. 6A. The distance is set to be three times or more the distance from the fitting hook 52 engaging with the action member 60 to the fitting groove 53.
 そして、本仕様においても、下側プレス部31の移動量を4mm以上確保するように、上端である嵌合用フック52から、支点となる嵌合溝53までの距離を10mm以上に設定する。 Also, in this specification, the distance from the fitting hook 52 at the upper end to the fitting groove 53 serving as a fulcrum is set to 10 mm or more so as to secure the moving amount of the lower press portion 31 of 4 mm or more.
 図12を参照して、力点部材50の中央アーム54において、嵌合溝53よりも持ち手55に近い部分であって、回転方向の先行面には、波打ち状に凹凸が形成されている。 参照 Referring to FIG. 12, in the central arm 54 of the power point member 50, a portion closer to the handle 55 than the fitting groove 53, and the leading surface in the rotation direction is formed with wavy irregularities.
 この波打ち凹凸形状541,542により、フィット性が向上する。特に、自分でメイクする場合、固定部材40側の持ち手46の指穴には親指を入れ、力点部材50側の持ち手55の指穴には、他の指を入れる。最も力が入りやすい中指を持ち手55の指穴に入れた場合、あるいは薬指を指穴に入れた場合、波打ち凹凸形状541,542により、人差し指や中指でも力点部材50を支持することになり、動作が安定する。 フ ィ ッ ト The undulations 541 and 542 improve the fit. In particular, when making makeup by yourself, a thumb is put in the finger hole of the handle 46 on the fixing member 40 side, and another finger is put in a finger hole of the handle 55 on the power point member 50 side. When the middle finger, into which the force is most likely to enter, is inserted into the finger hole of the handle 55, or when the ring finger is inserted into the finger hole, the wavy irregularities 541, 542 will support the force member 50 even with the index finger or the middle finger. Operation becomes stable.
 また、持ち手55のさらに後端には、指掛け部(フィンガーレスト、指置きともいう)56が設けられている。例えば、使用者が自分でまつ毛をカールする際、力点部材50側の持ち手55の指穴には中指を入れ、指掛け部56には薬指を入れる、或いは、力点部材50側の持ち手55の指穴には人差し指を入れ、指掛け部56には中指を入れる、または、力点部材50側の持ち手55の指穴には薬指を入れ、指掛け部56には小指を入れる。 指 Furthermore, at the rear end of the handle 55, a finger hook (also referred to as finger rest or finger rest) 56 is provided. For example, when the user curls the eyelashes by himself, the middle finger is inserted into the finger hole of the handle 55 on the power point member 50 side, the ring finger is inserted into the finger holder 56, or the handle 55 of the handle 55 on the power point member 50 side is inserted. The index finger is put in the finger hole, the middle finger is put in the finger hook part 56, or the ring finger is put in the finger hole of the handle 55 on the power point member 50 side, and the little finger is put in the finger hook part 56.
 このようにいずれの指を入れるにしても、持ち手55の指穴に入れた指以外で、力点部材50を、波打ち凹凸形状541,542、及び指掛け部56でサポートするため、まつ毛をカールする際、プッシュ時の1つの指への負担を分担させるとともに、動作が安定する。 Regardless of which finger is put in this way, the eyelashes are curled in order to support the emphasis member 50 with the wavy irregularities 541 and 542 and the finger hook portion 56, except for the finger put in the finger hole of the handle 55. In this case, the burden on one finger at the time of pushing is shared, and the operation is stabilized.
 また、固定部材40の持ち手46及び力点部材50の持ち手55を閉じた際に対向する部分であるには、ヒットポイント47,57がそれぞれ設けられている。 ヒ ッ ト Further, hit points 47 and 57 are provided in portions facing each other when the handle 46 of the fixing member 40 and the handle 55 of the power point member 50 are closed.
 まつ毛を押圧する際に、持ち手46,55のヒットポイント47,57の先端同士が当接することで、固定部材40に対する力点部材50の過剰な回転を防止する。 (4) When pressing the eyelashes, the tips of the hit points 47 and 57 of the handles 46 and 55 abut against each other, thereby preventing the power point member 50 from rotating excessively with respect to the fixing member 40.
 なお、持ち手46,55の内側内縁部にヒットポイント47,57を設けることで回転が規制されるため、例えば、繰り返し使用によりクリッパーゴム(不図示)が押しつぶされて薄くなった際に、押し込んだ際のプレス部のクランプ圧が足りなくなるおそれがある。そのため、ヒットポイント47,57を設置する際は、クリッパーゴムがつぶれた場合の含めて長さ等を設定すると好適である。 In addition, since the rotation is regulated by providing the hit points 47 and 57 on the inner inner edges of the handles 46 and 55, for example, when the clipper rubber (not shown) is crushed and thinned by repeated use, it is pushed in. In this case, there is a possibility that the clamping pressure of the press section becomes insufficient. Therefore, when setting the hit points 47 and 57, it is preferable to set the length and the like including the case where the clipper rubber is crushed.
 図13A,図13Bは、第2実施形態のアイラッシュカーラー3の正面図及び背面図である。 13A and 13B are a front view and a rear view of the eyelash curler 3 according to the second embodiment.
 図13A及び図13Bを参照して、力点部材50が回転する方向と直交する方向を奥行方向としたとき、固定部材40において、アーム(第1のアーム部)44の少なくとも一部と、持ち手46の、奥行方向における幅(x2)が等しい。また、力点部材50において、第2のアーム部51,54の少なくとも一部と、持ち手55の、奥行方向における幅(x2)が等しいことがわかる。 Referring to FIGS. 13A and 13B, when a direction orthogonal to the direction in which force point member 50 rotates is defined as a depth direction, at least a part of arm (first arm portion) 44 and a handle in fixing member 40 are provided. 46 have the same width (x2) in the depth direction. Further, in the power point member 50, it can be seen that the width (x2) in the depth direction of at least a part of the second arm portions 51 and 54 and the handle 55 is equal.
 なお、本実施形態では、波打ち凹凸形状541,542やヒットポイント47,57が設けられているため、アーム部44,51,54や持ち手46,55の梁の回転方向の厚み(高さ)及び幅は均一ではない。 In this embodiment, since the wavy irregularities 541 and 542 and the hit points 47 and 57 are provided, the thickness (height) of the beams of the arms 44, 51 and 54 and the handles 46 and 55 in the rotation direction is provided. And the width is not uniform.
 しかし、本実施形態においても、アーム44,51,54の奥行き方向(幅x2の方向)の中心線CLは、持ち手46,55の中心線CLと同じ方向に延伸し、重なっている。そのため、操作時に、指からの挟む力が持ち手46,55から、同じ中心線上に延伸するアーム部44,51,54を介して、まっすぐに加わるため、まつ毛の挟み込みの力が伝達されやすい。 However, also in the present embodiment, the center line CL in the depth direction (direction of width x2) of the arms 44, 51, 54 extends in the same direction as the center line CL of the handles 46, 55 and overlaps. Therefore, at the time of operation, a force for pinching from the fingers is applied straight from the handles 46, 55 via the arms 44, 51, 54 extending on the same center line, so that the force for pinching the eyelashes is easily transmitted.
 また、図10、図11、図12を参照して、固定部材40において、持ち手46は、1本のアーム44の下端から厚さ方向に分岐点BP1で分岐して、アーム44から直線状に延伸する直線部461と、該直線部461の下端から第1の厚さ方向に膨らんで折り返して分岐点BP1に戻る湾曲部462によって指穴を形成するように構成されている。 10, 11 and 12, in the fixing member 40, the handle 46 branches from the lower end of one arm 44 at the branch point BP1 in the thickness direction, and straightens from the arm 44. The finger hole is formed by a straight portion 461 extending to the right and a curved portion 462 that bulges from the lower end of the straight portion 461 in the first thickness direction and turns back to return to the branch point BP1.
 また、力点部材50において、持ち手55は、1本のアーム部51,54の下端から厚さ方向に分岐点で分岐して、アーム部51,54の一部である中央アーム54から直線状に延伸する直線部551と、該直線部551の下端から前記第1の厚さ方向とは反対方向の第2の厚さ方向に膨らんで折り返して分岐点に戻る湾曲部552によって指穴を形成するように構成されている。 In the power point member 50, the handle 55 branches off from the lower end of one of the arms 51, 54 at a branch point in the thickness direction, and extends straight from the central arm 54, which is a part of the arms 51, 54. A finger hole is formed by a straight portion 551 extending to the right and a curved portion 552 that bulges from a lower end of the straight portion 551 in a second thickness direction opposite to the first thickness direction, returns and returns to a branch point. It is configured to be.
 本実施形態は、持ち手46,55に形成された指穴は、略半円形状である。 は In the present embodiment, the finger holes formed in the handles 46 and 55 are substantially semicircular.
 図10~図13Bを参照して、固定部材40の持ち手46の直線部461と湾曲部462と、力点部材50の持ち手55の直線部551と湾曲部552は、奥行方向において重なっている。 With reference to FIGS. 10 to 13B, the straight portion 461 and the curved portion 462 of the handle 46 of the fixing member 40 and the straight portion 551 and the curved portion 552 of the handle 55 of the power point member 50 overlap in the depth direction. .
 さらに、本構成においても、持ち手46,55の直線部と湾曲部とで、奥行き方向に重なっているため、力がまっすぐに掛かり、より操作しやすく、まつ毛への力が加わりやすい。 Further, also in this configuration, since the straight portions and the curved portions of the handles 46 and 55 overlap in the depth direction, the force is applied straight, the operation is easier, and the force on the eyelashes is easily applied.
 本実施形態においても、図8Bに示した断面係数とヤング率で規定された実施可能範囲に入る樹脂を用いることで、金属製と同等のしなり及びクランプ圧により、同等の応力を実現できる。そのため、持ち手のホールド性を向上させながら、金属製の形状から大型化することなく、強度を担保して、金属製と同様の操作により、金属製と同等のまつ毛カール効果を発揮できる。 に お い て Also in this embodiment, by using a resin that falls within the operable range defined by the section modulus and the Young's modulus shown in FIG. 8B, the same stress can be realized by the same bending and clamping pressure as those made of metal. Therefore, while improving the holding property of the handle, the strength can be secured without increasing the size of the metal shape, and the same eyelash curl effect as that of the metal can be exhibited by the same operation as that of the metal.
 なお、第2実施形態では、作用点(支点A)及び支点(支点B)を構成要素同士のフックと溝を用いて係合する構成において、波打ち凹凸形状541,542やヒットポイント47,57が設けられている例を用いたが、波打ち形状やヒットポイントを、ピン軸によって係合する第1実施形態に適用してもよい。 In the second embodiment, in the configuration in which the action point (the fulcrum A) and the fulcrum (the fulcrum B) are engaged using the hooks and the grooves of the components, the wavy irregularities 541 and 542 and the hit points 47 and 57 are formed. Although the example provided is used, a wavy shape or a hit point may be applied to the first embodiment in which the pin shape engages.
 あるいは、構成要素同士をフックと溝を用いて係合する第2実施形態の構成において、波打ち凹凸形状541,542やヒットポイント47、57を設けなくてもよい。 Alternatively, in the configuration of the second embodiment in which the components are engaged with each other using the hooks and the grooves, the wavy irregularities 541 and 542 and the hit points 47 and 57 may not be provided.
 また、作用点及び支点を構成要素同士のフックと溝を用いて係合する構成において、第1実施形態のように、アーム部14,21,24と持ち手16,25の梁が、幅に加えて厚さも等しくなるように構成してもよい。 Further, in the configuration in which the action point and the fulcrum are engaged using the hooks and the grooves of the components, the beams of the arms 14, 21, 24 and the handles 16, 25 have a width as in the first embodiment. In addition, the thickness may be configured to be equal.
 また、第1実施形態では、略涙型の指穴が形成された持ち手、第2実施形態では、略半円形の指穴が形成されや持ち手について説明したが、指穴の形状は逆であってもよく、あるいは、円形、楕円形状等であってもよい。さらに、持ち手において、湾曲部の分岐点周辺が途切れている形状であってもよい。 Further, in the first embodiment, a handle having a substantially tear-shaped finger hole is described, and in the second embodiment, a substantially semi-circular finger hole is formed or the handle is described. However, the shape of the finger hole is reversed. Or a circular or elliptical shape. Further, the handle may have a shape in which the vicinity of the branch point of the curved portion is interrupted.
