Description

化粧道具およびアイラッシュカーラーMakeup tools and eyelash curlers
 本発明は、化粧道具およびアイラッシュカーラーに関する。 The present invention relates to a makeup tool and an eyelash curler.
 一般的に、アイラッシュカーラー(まつげカール器、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, buhler) has a configuration using the principle of leverage, and is made of 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、肌に接触する部分として、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 area, the parts that correspond to the skin, such as the gripping parts that the fingers contact and the contact surfaces that the eyelids contact, are made of resin from above the metal. There have been proposed eyelash curlers that partially cover or partially constitute a resin member (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).
日本国実用新案出願公開昭和59-40002号公報Japanese Utility Model Application Publication No. 59-40002 日本国特開2007-68695号公報Japanese Patent Application Laid-Open No. 2007-68695 日本国特開2004-57581号公報Japanese Patent Application Laid-Open No. 2004-57581
 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、生産性が低下してしまった。 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. The productivity has declined as much.
 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作成しようとすると、挟み込みに強度が足りないため、特許文献3に示す、外側全体の樹脂製のアイラッシュカーラーは、挟み込みのためのバネを有し、複雑で大型な構成であって、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、操作方法が異なっていた。 In addition, when trying to create a resin eyelash curler having the same shape as a general metal shape, the strength of the pinch is insufficient, so that a resin eyelash curler of the entire outer side shown in Patent Document 3 is used for pinching. It has a spring, and has a complicated and large-sized configuration, and has a similar appearance and a different operation method 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、樹脂製の化粧道具の提供を目的とする。 Therefore, the present invention has been made in view of the above circumstances, and aims to provide a resin-made makeup tool capable of performing the same operation as that of a metal, while ensuring strength without increasing the size of a general metal shape. I do.
 上記課題を解決するため、本発明の一態様では、
ヤング率が2500N/mm2~40000N/mm2の樹脂材料で形成され、少なくとも最大応力発生箇所は断面係数が5mm3~40mm3に構成される化粧道具、を提供する。
In order to solve the above problems, in one embodiment of the present invention,
Young's modulus is made of a resin material of 2500N / mm 2 ~ 40000N / mm 2, at least the maximum stress generating portion is section modulus provides a cosmetic tool configured to 5mm 3 ~ 40mm 3.
 一態様によれば、樹脂製の化粧道具において、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。 According to one aspect, in a resin-made makeup tool, the same operation as that of a metal-made makeup tool can be performed without increasing the size of a general metal-made makeup tool while ensuring strength.

 上まつ毛をカールする際に、図1に示す状態でアイラッシュカーラー1は把持され、下側プレス部(下当接部材、挟圧片)31は、上側プレス部11との間に挟んだまつ毛の下面を下側から押し上げて、上まつ毛を上向きに癖付けする。 When curling the upper eyelashes, the eyelash curler 1 is gripped in the state shown in FIG. 1, and the lower press portion (lower abutting member, pressure piece) 31 is positioned between the upper press portion 11 and the lower surface of the eyelashes Push up from below to make the upper lashes habit upward.
 また、下まつ毛をカールする際に、アイラッシュカーラー1は図1とは上下逆さまに把持され、下側プレス部31は、上側プレス部11との間に挟んだまつ毛の上面を、上側から押し下げて、下まつ毛を下向きに癖付けする。 Also, when curling the lower eyelashes, the eyelash curler 1 is gripped upside down from FIG. 1, and the lower press part 31 pushes down the upper surface of the eyelashes sandwiched between the upper press part 11 from above, Habit the lower lashes downward.
 リンク部(昇降支柱)32A,32Bは、上端が下側プレス部と連接され、略V状に傾斜して、下端が連結部33と連接している。 The upper ends of the link portions (elevating columns) 32A and 32B are connected to the lower press portion, are inclined in a substantially V shape, and the lower ends are connected to the connecting portion 33.
 連結部33は立体的なU字(コの字)状の形状である。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-shape (U-shape). 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、先端側係合孔22と、連結部33の側面の小孔331A,332Bとが一致した状態で、先端側係合孔22及び小孔331A,332Bを貫通するように、ピン軸PS1で係止される。 The distal end of the distal side arm 21 of the power point member 20 is inserted inside the U-shape of the connecting portion 33 of the operation member 30, and the distal side engaging hole 22 and the small holes 331 </ b> A and 332 </ b> B on the side surface of the connecting portion 33 coincide with each other. In this state, it is locked by the pin shaft PS1 so as to pass through the front end side engagement hole 22 and the small holes 331A, 332B.
 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)311A,311Bが設けられている。係合フック311A,311Bが、一対の支柱12A,12Bに対して係合することで、固定部材10の支柱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, substantially circular (hook-shaped) engagement hooks (engagement portions) 311A and 311B are provided. The engagement hooks 311A and 311B engage with the pair of columns 12A and 12B, thereby enabling the fixing member 10 to slide along the columns 12A and 12B.
 なお、使用の際には、下側プレス部31の上面の溝には、弾性部材であるクリッパーゴムR(図17(a)参照)が挟まれて、セットされる。 In use, the clipper rubber R (see FIG. 17A), which is an elastic member, is set in the groove 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、第2の係合孔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との連結する先端側係合孔22が、持ち手25の移動とは反対の方向に上下に移動し、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 at one end is moved closer to the handle 16, the power point member 20 moves the pin shaft PS <b> 2, which is a connection portion between the second engagement hole 23 and the small holes 151 </ b> A and 151 </ b> B, into place. By rotating as a fulcrum (fulcrum B), the distal end side engagement hole 22 connected to the connection portion 33 with the action member 30 at the other end moves up and down in a direction opposite to the movement of the handle 25. Then, the action member 30 is pushed up together with the pin shaft PS1.
 これより、持ち手25を移動させることで、作用部材30は、先端側係合孔22の昇降に応じて、係合フック311A,311Bが、固定部材10の支柱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。 Thus, by moving the handle 25, the operating member 30 causes the engaging hooks 311A, 311B to slide along the columns 12A, 12B of the fixed member 10 in accordance with the elevation of the distal end side engaging hole 22. Then, the lower press unit 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、弾性部材(クリッパーゴムR)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 eyelashes between the elastic member (the clipper rubber R) and the upper press portion 11. This gives the lashes a habit.
 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.
 <比較例>
 図3は、比較例の金属製のアイラッシュカーラー9の図である。図3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。
<Comparative example>
FIG. 3 is a diagram of a metal eyelash curler 9 of a comparative example. The eyelash curler 9 shown in FIG. 3 is an example of a general metal eyelash curler.
 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3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、細い金属棒のフレームとが別々に形成された後、接着される。 In the metal eyelash curler 9 shown in FIG. 3, the fixing member 70 is bonded after the upper press portion (metal frame) 11 and the thin metal rod 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 frame of 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、金属棒の上側の支柱72A,72Bに相当する両端部において、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 rod, the lower end is twisted in a ring shape to form a handle 76, and opposing portions at both ends corresponding to the upper columns 72 </ b> A and 72 </ b> B of the metal rod. Is formed with a long slit. 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、図1に示した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、持ち手と同じ太さである。 On the other hand, since the eyelash curler 1 of the present invention shown in FIG. 1 is made of resin, the arm 14 (21, 24) of the fixing member 10 and the power point member 20 is made of one piece, It is the same thickness as.
 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。 In the configuration of the present invention, in the fixing member 10 and the power point member 20, the cross-sectional shape of the handles 16, 25 is made the same as that of the arms 14, 21, 24, so that the handles 16, 25 can be made thick. As a result, the holdability is improved, and even if force is applied, it does not sink into the finger and does not hurt, so that sufficient force can be applied.
 ここで、本発明者は、樹脂製のアイラッシュカーラーの強度検証のために、金属製のアイラッシュカーラーにおける力の掛かり方について検討し、実験を行った。 Here, the present inventor studied how to apply a force to a metal eyelash curler and conducted an experiment in order to verify the strength of the resin eyelash curler.
 <形状の検討(はねだし単純梁の近似)>
 前提として、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。
<Examination of shape (approximation of simple beams)>
As a premise, since the eyelash curler has a complicated shape, the shape was calculated by replacing it with a simple shape.
 図4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4において、上図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、下図は、アイラッシュカーラー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。 FIG. 4 is a diagram for explaining how to apply a force in the eyelash curler by approximation. In FIG. 4, the upper diagram shows the positions of the fulcrum and the load point in the eyelash curler, and the lower diagram shows the fulcrum and the load point of the eyelash curler, which are approximated to a simple beam (one-side concentrated load).
 睫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、アイラッシュカーラーの連結部は、支点A,Bに置き換えることが出来る。 At the moment when the eyelashes are sandwiched, 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 can be replaced with fulcrums A and 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5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 a simple beam that protrudes, and when considering load and 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.
 図5は、力を受ける部分である固定部材及び力点部材を構成するから成る梁の一例の断面の幅(奥行)(x)及び高さ(y)の説明図である。なお、図5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の断面形状は、図5に示す矩形に限られず、円形や、楕円形、半円形などの他の形状であってもよい。 FIG. 5 is an explanatory diagram of a width (depth) (x) and a height (y) of a cross section of an example of a beam composed of a fixed member and a power point member which are portions receiving a force. Note that the configuration of the beam having a rectangular cross section shown in FIG. 5 is an example, and the cross-sectional shapes of the fixing member 10 and the power point member 20 are not limited to the rectangle shown in FIG. 5, but may be circular, elliptical, semicircular, or the like. Other shapes may be used.
 また、図4に示した、「はねだし単純梁(片側集中荷重)」の公式では支点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 formula of “spring out simple beam (single-side concentrated load)” shown in FIG. 4, 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、(図6~図14参照)樹脂の選定を行った。 Therefore, the present inventor selected a resin (see FIGS. 6 to 14) by a simulation based on an existing metal eyelash curler when external force (load P) is applied to the eyelash curler as an object. .
 [グリップ力、クランプ圧の考察]
 ((実験例1))
 樹脂製のアイラッシュカーラーの強度を確保するために、前提として、図3に示す比較例の金属製のアイラッシュカーラー9を用いた際のクランプ圧(クリップ圧)を調査する実験を行った。
[Consideration of grip force and clamp pressure]
((Experimental example 1))
In order to ensure the strength of the resin-made eyelash curler, an experiment was conducted as a premise for investigating the clamp pressure (clip pressure) when using the metal eyelash curler 9 of the comparative example shown in FIG.
 本実験では、複数の被験者に、図3に示すアイラッシュカーラー9を用いて、通常使用時と同様に使用してもらい、その際のクランプ圧を測定した。金属製のアイラッシュカーラーは、一般的なステンレス製のものを用いた。 In this experiment, a plurality of test subjects were used in the same manner as in normal use using the eyelash curler 9 shown in FIG. 3, and the clamp pressure at that time was measured. As a metal eyelash curler, a general stainless steel eyelash curler was used.
 本実験において、6人の被験者を対象として、金属製のアイラッシュカーラーの使用時圧力であるクランプ圧を測定した。この際、まつ毛を挟む部分である、下側プレス部91の上に設置されるクリッパーゴムRの直下に圧力センサーR(図14参照)を設置したハンドメイド式の測定機構を用いて、睫毛を挟む圧力のクランプ圧を測定した。なお、クランプ圧は、自作の圧力センサーを用いて測定したため、指標であって、単位は設定していない。 ク ラ ン プ In this experiment, the clamp pressure, which was the pressure when using a metal eyelash curler, was measured for six subjects. At this time, the eyelashes are sandwiched by using a hand-made measuring mechanism in which a pressure sensor R (see FIG. 14) is installed immediately below a clipper rubber R installed on the lower press portion 91, which is a portion for sandwiching the eyelashes. The pressure clamping pressure was measured. Note that the clamp pressure was measured using a self-made pressure sensor, and is therefore an index, and the unit is not set.
 図6に、金属製アイラッシュカーラー9の使用時のまつげクランプ圧を、ハンドメイド式測定機構で測定した測定結果を示す。図6の(a)~(f)のグラフにおいて、縦軸はクランプ圧、横軸は時間(単位:秒)を示す。6人の被験者は、20代~50代の男女であって、人物A、人物B、人物C、人物D、人物E、人物Fとする。 FIG. 6 shows the results of measuring the eyelash clamping pressure when using the metal eyelash curler 9 using a hand-made measuring mechanism. In the graphs (a) to (f) of FIG. 6, the vertical axis represents the clamping pressure, and the horizontal axis represents time (unit: seconds). The six subjects are men and women in their twenties to fifties, and are assumed to be person A, person B, person C, person D, person E, and person F.
 ここで、図6に示すように、クランプ圧の最大値は、それぞれ、328.26、498.34、380.67、318.58、238.9、257.33であった。 Here, as shown in FIG. 6, the maximum values of the clamping pressure were 328.26, 498.34, 380.67, 318.58, 238.9, and 257.33, respectively.
 そこで、下記の樹脂製のアイラッシュカーラーに対するクランプ圧の最大値は、上記実験での最大値498.34に少し余裕を持たせて、クランプ圧500を目標値と設定して実験した。 Therefore, the maximum value of the clamping pressure for the resin-made eyelash curler described below was set to a target value with a margin of 498.34 in the above-mentioned experiment, with a margin.
 (目標値に対応する圧力)
 また、上述のように、実際の被験者が使用することでクリッパーゴムRに掛かる圧力は、クランプ圧として測定できるが、持ち手16,25にかかる力の人力によるクランプ圧を、持ち手への機械等で印加可能な荷重(外力)としての圧力(N)に換算するために数値について検討した。
(Pressure corresponding to target value)
Further, as described above, the pressure applied to the clipper rubber R by the use of the actual subject can be measured as the clamp pressure. However, the clamp pressure due to the manual force applied to the handles 16 and 25 is applied to the mechanical Numerical values were examined in order to convert the pressure (N) as a load (external force) that can be applied by the above method.
 まず、金属製のアイラッシュカーラー1でクランプ圧500となるときの荷重Pを、試験機とハンドメイド式の圧力センサー(図17(a)参照)で測定し導き出した値が、持ち手ごとに10Nである。詳しくは、クランプ圧が500(図19実線参照)の前後で、持ち手に印加する荷重であるグリップ力は17N~21N(図18実線参照)であるため、略中央値の20Nとして、持ち手16,25両方で半分ずつに振り分けて10Nを導いた。 First, the load P when the metal eyelash curler 1 reaches a clamping pressure of 500 is measured by a tester and a handmade pressure sensor (see FIG. 17A), and the derived value is 10 N for each handle. . More specifically, since the grip force, which is the load applied to the handle, is about 17N to 21N (see the solid line in FIG. 18) before and after the clamping pressure is 500 (see the solid line in FIG. 19), the handle is set to approximately the median value of 20N. Both 16 and 25 were divided in half and 10N was led.
 なお、P=10Nを用いて、上述の「はねだし単純梁(片側集中荷重)」における、支点B周辺に発生する曲げモーメントMBは、下記式で表される。
MB = P(荷重) ×b(長さ)
Note that, using P = 10N, the bending moment MB generated around the fulcrum B in the above “spring-out simple beam (one-side concentrated load)” is expressed by the following equation.
MB = P (load) xb (length)
 今回は、後述する構成例において、
a =12mm    
b =50mmにより
MB = P ×b = 10(N) × 50 =500N・mmとなる。
This time, in the configuration example described later,
a = 12mm
b = 50mm
MB = P × b = 10 (N) × 50 = 500 N · mm
 この、持ち手への荷重10Nをカール効果が期待できる荷重値として考慮して、下記の素材の選定や、後述の耐久実験を行った。 し て The following materials were selected and a durability test described below was performed, taking into account the load of 10 N on the handle as a load value at which the curl effect can be expected.
 <素材の選定>
 ((実験例2))
 本発明者は、素材別に、固定部材10及び力点部材20である梁の幅(x)や高さ(y)を変化させて、機械的強度判定、成形性判定に基づいて、総合判定を行った。この際、外力(グリップ力)として、両方の持ち手に対して、上記で算出した10Nの荷重を印加した。
<Selection of material>
((Experimental example 2))
The present inventor makes a comprehensive judgment based on the mechanical strength judgment and the formability judgment by changing the width (x) and the height (y) of the beam as the fixing member 10 and the power point member 20 for each material. Was. At this time, a load of 10 N calculated above was applied to both handles as an external force (grip force).
 図7は、SUS製と、6PA+GF55%樹脂製のアイラッシュカーラーを比較する判定表を示す。 FIG. 7 shows a judgment table for comparing an eyelash curler made of SUS and a 6PA + GF55% resin.
 金属製のアイラッシュカーラー9は、一般的にステンレス製(SUS304)であることが多い。図7の6PA+GF55%樹脂のアイラッシュカーラー1は、一般的なステンレス製のアイラッシュカーラーを模して成形したものである。 The metal eyelash curler 9 is generally often made of stainless steel (SUS304). The eyelash curler 1 of 6PA + GF55% resin in FIG. 7 is formed by imitating a general stainless steel eyelash curler.
 ここで、ヤング率(N/mm2)は、同軸方向のひずみと応力の比例定数、縦弾性係数を示す。断面係数Z(mm3)は、部材の断面性能を表す指標であって、具体的には曲げに対する強さ・抵抗力である。 Here, the Young's modulus (N / mm 2 ) indicates a proportional constant of strain and stress in the coaxial direction and a longitudinal elastic modulus. The section modulus Z (mm 3 ) is an index indicating the section performance of the member, and specifically, is a strength / resistance to bending.
 図7、図8における各条件での判定は、下記の基準で判断した。 判定 The judgments under each condition in FIGS. 7 and 8 were based on the following criteria.
 機械的強度判定:使用時に材料に発生する応力値が材料そのものの強度以下なる場合になることで、力が加わるように剛性が確保できていることで判定した。 判定 Judgment of mechanical strength: Judgment was made when the value of the stress generated in the material during use became less than the strength of the material itself, and the rigidity was secured to apply a force.
 成形性判定:成形するに際し不良が発生しないかどうか判定した。 (4) Moldability judgment: Judgment was made as to whether or not defects occurred during molding.
 総合判定:機械的強度、成形性の総合的な判定である。 Comprehensive judgment: Comprehensive judgment of mechanical strength and moldability.
 なお、これらの判定は、金属製アイラッシュカーラー1及び6PA+GF55%樹脂製アイラッシュカーラー1の断面係数4.5の構成を除き、CAE(Computer Aided Engineering)演算によるシミュレーション上の判定である。 These judgments are simulation judgments by CAE (Computer Aided Engineering) except for the configuration of the metal eyelash curler 1 and the 6PA + GF55% resin eyelash curler 1 having a section coefficient of 4.5.
 図6の表に示すように、一般的なステンレス製(SUS304)の金属製のアイラッシュカーラー9は、持ち手16,25に10Nずつ荷重を掛けた際、固定部材10及び力点部材20からなる梁の幅xや、高さyが2.75mmと小さくても、引張強さ(強度)が十分に大きく、たわみ量が小さいため、すべての判定をクリアしている。 As shown in the table of FIG. 6, a general stainless steel (SUS304) metal eyelash curler 9 has a beam composed of the fixing member 10 and the force point member 20 when a load of 10 N is applied to the handles 16, 25. Even if the width x and the height y are as small as 2.75 mm, all the judgments are cleared because the tensile strength (strength) is sufficiently large and the amount of deflection is small.
 これに対して、例えばPA(ポリアミド)+GF(ガラスファイバー(ガラス繊維))55で、梁10,20の幅x、高さyが金属製と近い3mmの樹脂製のアイラッシュカーラーでは、たわみ量が大きくなるため、すべての判定が×(NG)になっている。 On the other hand, for example, in a resin eyelash curler of PA (polyamide) + GF (glass fiber (glass fiber)) 55 and the width x and height y of the beams 10 and 20 are 3 mm, which is close to that of metal, the deflection amount is large. Therefore, all the judgments are x (NG).
 また、本発明者は、PA+GF55%樹脂について、梁部(固定部材10、力点部材20)の幅及び高さを徐々に変化させた場合について、図7と同様のシミュレーション上の判定を行った。 {Circle around (4)} The inventor made a simulation determination similar to that in FIG. 7 for the case where the width and height of the beam portion (fixing member 10 and power point member 20) were gradually changed for PA + GF 55% resin.
 図8は、6PA+GF55%樹脂を素材として、梁の幅x及び高さyを変化させることで断面係数を変化させた判定表である。図8では、PA+GF55%の樹脂製のアイラッシュを用いて、梁の寸法(幅、高さ)を変化させて評価した結果を示す。 FIG. 8 is a judgment table in which the section modulus is changed by changing the width x and the height y of the beam using 6PA + GF55% resin as a material. FIG. 8 shows the results of evaluation by changing the dimensions (width, height) of the beam using an eyelash made of resin of PA + GF55%.
 図8に示すように、PA+GF55%樹脂で構成した場合であっても、梁10,20の幅xや高さyを増加させることで、判定を「○」にすることができる。 判定 As shown in FIG. 8, even in the case of the PA + GF 55% resin, the judgment can be made “○” by increasing the width x and the height y of the beams 10 and 20.
 上記の図8を算出した結果から射出成形時の肉厚に依る成形性、アイラッシュカーラーを使用時の操作性を考慮して、ヤング率が2500~40000(N/mm2)の範囲の中で断面係数5~40(mm3)が最適と思われる。その理由を下記説明する。 From the result of calculating FIG. 8 described above, considering the moldability depending on the wall thickness during injection molding and the operability when using an eyelash curler, the cross section is within the range of Young's modulus of 2500 to 40,000 (N / mm 2 ). A coefficient of 5 to 40 (mm 3 ) seems to be optimal. The reason will be described below.
 図9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10は、断面係数とヤング率で規定された本発明の素材の推奨範囲を示す図である。 FIG. 9 shows the evaluation results when an eyelash curler is formed from a plurality of materials and used, and FIG. 10 is a diagram showing the recommended range of the material of the present invention defined by the section modulus and the Young's modulus.
 詳しくは、図9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)、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、ナイロン6/10、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、断面係数7.5~32(mm3)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. 9 shows SUS304 (stainless), polyamide (PA), a fiber reinforced resin obtained by adding 55% of glass fiber (GF) to PA, nylon 6/10, Evaluation results of polyether ether ketone (PEEK), polybutylene terephthalate (PBT), GF polyamide MXD6, and CF polyamide MXD6 when an eyelash curler having a dimension satisfying a cross-sectional coefficient of 7.5 to 32 (mm 3 ) was used. It is.
 なお、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って、ここで用いた、ガラス強化ポリアミドMXD(PAMXD6+GF50)は、ポリアミドMXD6にガラス繊維(GF)が50%配合された、市販のレニー(登録商標)1022Hを用いた。カーボン強化ポリアミドMXD6はポリアミドMXD6にカーボン繊維(CF)を40%配合された市販のレニーC408を用いた。 The polyamide MXD6 is a crystalline thermoplastic polymer obtained from meta-xylylenediamine (MXDA) and adipic acid, and the glass-reinforced polyamide MXD (PAMXD6 + GF50) used here is made of polyamide MXD6 made of glass fiber ( Commercially available Reny (registered trademark) 1022H containing 50% of (GF) was used. As carbon reinforced polyamide MXD6, commercially available Reny C408 obtained by mixing 40% of carbon fiber (CF) with polyamide MXD6 was used.
 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10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。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 section modulus increases, and the position on the graph of FIG. 10 moves upward, so that the evaluation is 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)、強度評価を満たさなかった。 Further, as for PBT, the strength evaluation was not satisfied even if the cross-sectional area was increased similarly to “PA + GF 55%” (even when the cross-sectional modulus was 32 (mm 3 )).
 図10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. 10, 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て、図10の推奨範囲に入れるためには、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10のグラフ上の位置が右方向に移動することになる。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、カーボン繊維)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。 Therefore, in order to increase the strength of the material containing resin without increasing the cross-sectional area and to fall within the recommended range of FIG. 10, the material constituting the eyelash curler was prepared by mixing glass fiber (GF) with resin. It is preferable to form with fiber reinforced resin. For example, when glass fiber is added to a resin having the same section modulus, the Young's modulus increases, and the position on the graph of FIG. 10 moves rightward. Further, CF (carbon fiber, 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 glass fiber (GF) or carbon fiber (CF) in an amount of 30% by mass or more and 65% by mass or less.
 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。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。よって、金属に近いまつ毛を挟む圧力を得ることができる。 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. 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. Therefore, a pressure for pinching the eyelashes close to the metal can be obtained.
 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(PET)、又は、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 (PET), or polyphenylene sulfide (PPS), and polyamide MXD6.
 なお、図9に示さなかった樹脂のヤング率の一例として、PEEKのヤング率は3900MPa程度、ガラス繊維強化PEEKは6300MPa程度、PETのヤング率は2800~4200MPa程度、ガラス繊維強化PETは9000~9900MPa程度、PETG、ガラス強化PETGのそれぞれのヤング率はPET、ガラス強化PETよりも少し大きい程度、PPSは3300MPa程度、ガラス繊維強化PPSは3900MPa程度である。なお、ガラス繊維強化樹脂は、ガラス繊維の配合割合によって、ヤング率が変化する。 As examples of the Young's modulus of the resin not shown in FIG. 9, the Young's modulus of PEEK is about 3900 MPa, the glass fiber reinforced PEEK is about 6300 MPa, the Young's modulus of PET is about 2800 to 4200 MPa, and the glass fiber reinforced PET is 9000 to 9900 MPa. The Young's modulus of PETG and glass reinforced PETG is slightly larger than PET and glass reinforced PET, PPS is about 3300 MPa, and glass fiber reinforced PPS is about 3900 MPa. The Young's modulus of the glass fiber reinforced resin changes depending on the mixing ratio of the glass fiber.
 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や、PA、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, PA, PEEK, PET, PETG, PPS, etc., the above is recommended. By setting the section modulus large within the range, 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における、応力発生範囲については、上記推奨範囲内のヤング率及び断面係数を満たすことが好ましいが、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の断面については、上記推奨範囲のヤング率を満たせば、断面係数は推奨範囲よりも小さくてもよい。 Here, with respect to the stress generation range in the fixing member 10 and the force point member 20 to which the force of the user's finger is directly applied, it is preferable to satisfy the Young's modulus and the section modulus within the above recommended range, but the force is indirectly applied. As for the cross section of the link portions 32A and 32B of the action member 30 performing the elevating operation, the section modulus may be smaller than the recommended range as long as the Young's modulus of the recommended range is satisfied.
 なお、ここでは、PA+GF55%について検討したが、アイラッシュカーラーを構成する強化樹脂(グラスファイバー)において、ガラスファイバーの含有量を増やした、PA+GF65%で形成すると、さらに強度を上昇させることもできる。 In this case, PA + GF 55% was examined here. However, when the reinforcing resin (glass fiber) constituting the eyelash curler is formed of PA + GF 65% with an increased glass fiber content, the strength can be further increased.
 さらに、本発明者は、上記で選定した素材の数値範囲に含まれる素材の一例を用いて、特定の寸法の第1実施形態のアイラッシュカーラーについて応力及び変形量の解析を行った。 Furthermore, the inventor analyzed stress and deformation of the eyelash curler of the first embodiment having specific dimensions using an example of a material included in the numerical range of the material selected above.
 <第1実施形態と解析>
 ((実験例3))
 本発明者は、CAE(Computer Aided Engineering)によって強度を担保できる寸法として、図11に示す寸法の第1実施形態に係るアイラッシュカーラーを形成し、解析、測定実験を行った。
<First Embodiment and Analysis>
((Experimental example 3))
The inventor formed an eyelash curler according to the first embodiment having dimensions shown in FIG. 11 as dimensions capable of ensuring strength by CAE (Computer Aided Engineering), and conducted analysis and measurement experiments.
 図11は、第1実施形態の樹脂製アイラッシュカーラー1の一例における各部の断面係数を示す図である。 FIG. 11 is a diagram showing the section modulus of each part in an example of the resin eyelash curler 1 of the first embodiment.
 後述の解析や実験で用いるアイラッシュカーラー1では、図11で示した下記寸法で形成した。これの寸法は、CAEによって、強度を担保できる寸法として算出された寸法に相当している。 ア イ The eyelash curler 1 used in the analysis and experiment described later was formed with the following dimensions shown in FIG. These dimensions correspond to dimensions calculated by the CAE as dimensions that can ensure strength.
 この構成では、下記の断面係数に設定されている。
固定部材10の断面係数Z=14.98mm3
力点部材20の持ち手側の断面係数Z=14.98mm3
力点部材20の先端側の断面係数Z=10.92mm3
作用部材Cの支持部の断面係数Z=1.57mm3
In this configuration, the section modulus is set as follows.
Section modulus Z of the fixing member 10 is 14.98 mm 3.
Section modulus Z on the handle side of the power point member 20 is 14.98 mm 3.
Section modulus Z on the tip side of the power point member 20 = 10.92 mm 3
Section modulus Z of the supporting portion of the working member C = 1.57 mm 3
 なお、力点部材20において、支点Aと支点Bに挟まれた部分を太くし過ぎると、力点部材の回転時に、先端側アーム21の先端部の移動に際して操作性が低下するおそれがあり、また、力点部材20において、上述の図4で示したように、持ち手25側の変位量が大きいため、後端側が太くすることが望まれる。そのため、上記のように、力点部材20の先端側アーム21において、太さを2段階に設定した。 If the portion sandwiched between the fulcrum A and the fulcrum B in the power point member 20 is too thick, the operability may decrease when the distal end portion of the distal end arm 21 moves when the power point member rotates. In the power point member 20, as shown in FIG. 4 described above, since the displacement amount on the handle 25 side is large, it is desired that the rear end side be thick. Therefore, as described above, the thickness of the distal end arm 21 of the power point member 20 is set to two levels.
 なお、上記断面係数は矩形を前提として算出しているが、断面は、円や六角形など等であってもよい。 Although the section modulus is calculated on the premise of a rectangle, the section may be a circle, a hexagon, or the like.
 図12は、6PA+GF55%樹脂で構成された、アイラッシュカーラー1に対する解析条件を示す図である。 FIG. 12 is a diagram showing analysis conditions for the eyelash curler 1 composed of 6PA + GF55% resin.
 図12に示すように、固定部材10の上端部である上側プレス部11の両端とXYZ軸を固定して、固定部材10と、力点部材20との交点であるヒンジ部(支点B)とを、摩擦なしで固定した。 As shown in FIG. 12, the XYZ axes are fixed to both ends of the upper press portion 11, which is the upper end of the fixing member 10, and the hinge portion (fulcrum B), which is the intersection of the fixing member 10 and the power point member 20, is fixed. , Fixed without friction.
 荷重として、持ち手部16,25に、25N+25Nの力を加えた。持ち手部16,25への荷重25Nはグリップ力50Nに相当する。なお、本実験で持ち手16,25へ印加する25N+25Nの荷重は、通常使用時よりも大きい荷重(負荷)である。 (4) A force of 25N + 25N was applied to the handles 16, 25 as a load. The load 25N applied to the handle portions 16, 25 corresponds to a grip force 50N. Note that the load of 25N + 25N applied to the handles 16, 25 in this experiment is a load (load) larger than that during normal use.
 これらの解析条件を用いて、本発明者は、図11のアイラッシュカーラー1における応力及び変形量についてCAE解析を行った。 Using these analysis conditions, the inventor performed a CAE analysis on the stress and deformation amount in the eyelash curler 1 of FIG.
 図13は、6PA+GF55%樹脂で構成された、図11のアイラッシュカーラー1において第2の解析条件で解析を行った際の、応力の分布を示す図である。 FIG. 13 is a view showing a stress distribution when the eyelash curler 1 of FIG. 11 is made of 6PA + GF55% resin and analyzed under the second analysis condition.
 図13で示すように、応力は、図4に示したはねだし単純梁(片側集中荷重))の構造から矛盾せず、固定部材10と力点部材20との連結部である支点B付近で最大応力が発生している。本構成では、力点部材20では、支点Bを挟んで高さ(y)が変化するため、支点B周辺において、高さが短くなった先端側に、応力が大きく発生する。なお、固定部材10及び力点部材20における、最大応力発生箇所は、図2で示した応力発生範囲であるアーム14及びアーム部21,24の範囲内である。 As shown in FIG. 13, the stress is consistent with the structure of the spring-out simple beam (one-side concentrated load) shown in FIG. 4, and is near the fulcrum B, which is the connection between the fixing member 10 and the power point member 20. Maximum stress is occurring. In the present configuration, since the height (y) of the power point member 20 changes with the fulcrum B interposed therebetween, a large stress is generated around the fulcrum B on the distal end side where the height is reduced. In addition, the maximum stress generation point in the fixing member 10 and the power point member 20 is within the range of the arm 14 and the arm portions 21 and 24 which is the stress generation range shown in FIG.
 図13では、通常使用時よりも大きい荷重をかけて、力点部材20の先端側アーム21の支点B周辺に、163.6MPaの応力がかかっている例を示しているが、通常使用時においても、応力が掛かりやすい部分は、同様である。 FIG. 13 shows an example in which a load of 163.6 MPa is applied around the fulcrum B of the distal end arm 21 of the power point member 20 by applying a larger load than in the normal use. The same applies to portions where stress is likely to be applied.
 図14は、6PA+GF55%樹脂で構成された、のアイラッシュカーラー1において第1の解析条件で解析を行った際の、変形量の分布を示す図である。 FIG. 14 is a diagram showing the distribution of the amount of deformation when the eyelash curler 1 composed of 6PA + 55% GF resin is analyzed under the first analysis condition.
 本実験では持ち手の移動量である変位量は指定しなかったが、図14に示す変形量は、両側の持ち手16,25に25Nずつ機械的な圧力を掛けても、持ち手16,25の内側同士は接触しないことがわかる。 In this experiment, the displacement amount, which is the movement amount of the handle, was not specified, but the deformation amount shown in FIG. 14 was obtained even when mechanical force was applied to the handles 16, 25 on both sides by 25 N each. It turns out that the inside of 25 does not contact.
 ((実験例4))
 また、本発明者は、図3に示す金属製のアイラッシュカーラー9と、図11に示す樹脂製アイラッシュカーラー1を、持ち手16,26が接触し始めるまで押し込んで、クランプ圧を測定する比較実験を行った。
((Experimental example 4))
In addition, the present inventor performed a comparative experiment in which the metal eyelash curler 9 shown in FIG. 3 and the resin eyelash curler 1 shown in FIG. 11 were pushed in until the handles 16 and 26 started to contact, and the clamp pressure was measured. Was.
 そのため、比較に用いた金属製のアイラッシュカーラー9の寸法について、図15に示す。図15は、図3に示す比較例の金属製アイラッシュカーラー9の寸法の一例を示す図である。 た め FIG. 15 shows the dimensions of the metal eyelash curler 9 used for comparison. FIG. 15 is a diagram showing an example of the dimensions of the metal eyelash curler 9 of the comparative example shown in FIG.
 各部の断面係数は下記の通りである。
固定部材10、力点部材20の断面係数Z=2mm3
作用部材30の断面係数Z=0.33mm3
The section modulus of each part is as follows.
Sectional modulus Z of fixing member 10 and force member 20 = 2 mm 3
Section modulus Z of action member 30 = 0.33 mm 3
 図16は、持ち手同士が接触を開始した際の、クランプ圧の測定結果を示す。本実験では、図17(a)に示すようにクリッパーゴムRの直下に圧力センサー210を設置して、クランプ圧を測定した。 FIG. 16 shows the measurement results of the clamp pressure when the hands start contacting each other. In this experiment, as shown in FIG. 17A, the pressure sensor 210 was installed immediately below the clipper rubber R, and the clamp pressure was measured.
 それぞれのアイラッシュカーラーの寸法の違いにより、持ち手16,25(76,85)の対向する面が接触し始めるまでの・変位量(移動量)は異なる。なお、樹脂製のアイラッシュカーラー1と金属製のアイラッシュカーラー9とを比較して、変位量は、持ち手16,25の指穴の内周側の指が接触する部分の移動量に相当するため、梁の寸法が太くなると、その分変位量が少し増える。 変 位 The amount of displacement (movement) until the opposing surfaces of the handles 16, 25 (76, 85) start to contact is different due to the difference in the dimensions of each eyelash curler. In addition, comparing the resin-made eyelash curler 1 and the metal-made eyelash curler 9, the amount of displacement corresponds to the amount of movement of the part of the fingers of the handles 16, 25 on the inner peripheral side of the finger holes. As the dimension of the element becomes thicker, the amount of displacement slightly increases.
 なお、比較例に係る金属製アイラッシュカーラー9は、以後実験では、SUS304ステンレスで構成された図15の寸法例のものを用いる。また、本実験で、図18、図19を測定した際の図11の寸法のアイラッシュカーラー1は、6PA+GF55%の樹脂で構成されている。 金属 As the metal eyelash curler 9 according to the comparative example, a size example shown in FIG. 15 made of SUS304 stainless steel will be used in the subsequent experiments. In this experiment, the eyelash curler 1 having the dimensions shown in FIG. 11 when measuring FIGS. 18 and 19 is made of 6PA + GF55% resin.
 図16に示したように、金属製のアイラッシュカーラー9の持ち手同士が接触し始めるのは23mm変位したときで、その際のクランプ圧は750である。樹脂製の図11のアイラッシュカーラー1の持ち手同士が接触し始めるのは23mm変位したときで、その際のクランプ圧は744である。 As shown in FIG. 16, the handles of the metal eyelash curlers 9 start contacting each other at a displacement of 23 mm, and the clamping pressure at that time is 750. The handle of the resin-made eyelash curler 1 shown in FIG. 11 comes into contact with each other when it is displaced by 23 mm, and the clamping pressure at that time is 744.
 持ち手同士が接触する状態のクランプ圧は、最大クランプ圧に相当する。図16からわかるように、図11の寸法の樹脂製のアイラッシュカーラー1では、最大クランプ圧は、金属製に近い744となった。そのため、図11のアイラッシュカーラー1では、金属製と同等の最大クランプ圧が達成できる。 ク ラ ン プ The clamp pressure when the handles are in contact with each other is equivalent to the maximum clamp pressure. As can be seen from FIG. 16, in the case of the resin-made eyelash curler 1 having the dimensions shown in FIG. 11, the maximum clamping pressure was 744, which is close to that of metal. Therefore, in the eyelash curler 1 of FIG. 11, a maximum clamping pressure equivalent to that of metal can be achieved.
 ((実験例5))
 本発明者は、図11に示した寸法の樹脂製アイラッシュカーラー1と、図15に示した寸法の金属製アイラッシュカーラー9のグリップ力とクランプ圧を測定した。
((Experimental example 5))
The inventor measured the grip force and the clamping pressure of the resin eyelash curler 1 having the dimensions shown in FIG. 11 and the metal eyelash curler 9 having the dimensions shown in FIG.
 図17は、装置により徐々に変化する荷重を与えてグリップ力、クランプ圧を測定するためのハンドメイド式の測定機構及び第1の測定機による荷重位置を示す図である。図17において(a)はクランプ圧を測定するための測定機構(ハンドメイド式の圧力センサー)を示す図であり、(b)は第1の試験機によってアイラッシュカーラーを固定する位置と荷重を架ける荷重位置を示す図である
 第1の測定環境では、試験機は、アイラッシュカーラー1,9に対して、図17(b)に示すように、持ち手16を下側にした状態で固定し、上側から、即ち、持ち手25の外側から荷重を加えている。
FIG. 17 is a view showing a hand-made measuring mechanism for measuring a grip force and a clamping pressure by giving a load that gradually changes by the device, and a load position by a first measuring machine. 17A is a diagram showing a measuring mechanism (a hand-made pressure sensor) for measuring a clamp pressure, and FIG. 17B is a diagram showing a position where an eyelash curler is fixed by a first tester and a load position where a load is applied. In the first measurement environment, the tester fixes the eyelash curlers 1 and 9 with the handle 16 on the lower side as shown in FIG. That is, the load is applied from outside the handle 25.
 また、クランプ圧(図19)の測定の際には、アイラッシュカーラー1(9)の睫毛を挟むための、図17(a)に示すように、下側プレス部31の溝部のクリッパーゴムRの直下に、回路基板220に接続された圧力センサー210を設置した状態で、図17(b)に示す位置に荷重がかかることで、上側プレス部11が降下する。この際、図17(b)に示す荷重位置に変化する荷重を与えた際に、回路基板220に圧力センサー210の測定値を記憶させるハンドメイド式の圧力測定機構で、上側プレス部11及びクリッパーゴムRにより下側プレス部31を押す圧力(挟み込み圧力)を測定する。 Also, when measuring the clamp pressure (FIG. 19), as shown in FIG. 17A, for holding the eyelashes of the eyelash curler 1 (9), immediately below the clipper rubber R in the groove of the lower press portion 31. In a state where the pressure sensor 210 connected to the circuit board 220 is installed, a load is applied to the position shown in FIG. At this time, when a load that changes to the load position shown in FIG. 17B is applied, the upper press unit 11 and the clipper rubber are a hand-made pressure measurement mechanism that stores the measurement value of the pressure sensor 210 on the circuit board 220. The pressure (pinching pressure) for pressing the lower press portion 31 is measured by R.
 なお、図17(a)に示す圧力センサー210は、図6で人の手による挟みこみを測定する際と同じものを用いた。このように、クリッパーゴムRの直下に圧力センサー210を設置して、睫毛を挟む圧力のクランプ圧を測定した。 The pressure sensor 210 shown in FIG. 17 (a) was the same as that used in FIG. 6 for measuring pinching by a human hand. In this manner, the pressure sensor 210 was installed immediately below the clipper rubber R, and the clamp pressure for clamping the eyelashes was measured.
 図18,図19は、第1実施形態の図11の樹脂製アイラッシュカーラー1と金属製のアイラッシュカーラー9を図17に示す測定環境で測定した際の測定結果である。図18は、グリップ力の比較を示し、図19は、クランプ圧の比較を示す。 FIGS. 18 and 19 show the measurement results when the resin eyelash curler 1 and the metal eyelash curler 9 of FIG. 11 of the first embodiment were measured in the measurement environment shown in FIG. FIG. 18 shows a comparison of grip force, and FIG. 19 shows a comparison of clamp pressure.
 図18に示すように、同じ変位量となるように必要なグリップ力は、金属製アイラッシュカーラー9と、樹脂製のアイラッシュカーラー1とでほぼ等しくなる。即ち、アイラッシュカーラー1は、比較例に係る金属製のアイラッシュカーラー9と、変形しやすさが等しいことがわかる。 As shown in FIG. 18, the grip force required to achieve the same displacement is substantially equal between the metal eyelash curler 9 and the resin eyelash curler 1. That is, it can be seen that the eyelash curler 1 is as easy to deform as the metal eyelash curler 9 according to the comparative example.
 また、図19から、同じ変位量となるようにグリップ力を付加したときに、樹脂製のアイラッシュカーラー1のクランプ圧は、金属製のアイラッシュカーラー9のクランプ圧とほぼ等しくなる。 From FIG. 19, when the grip force is applied so as to have the same displacement, the clamp pressure of the resin-made eyelash curler 1 becomes substantially equal to the clamp pressure of the metal-made eyelash curler 9.
 この実験により、図16に示したように最大クランプ圧が700以上となるアイラッシュカーラー1を用いて、図19に示すように、実使用時のクランプ圧を、目標値である500程度になるような変位量として、使用時の変位量を14mmに設定することができる。詳しくは、アイラッシュカーラー1では、図16の持ち手16,25同士が接触する位置まで変位するクランプ圧(最大クランプ圧:744)と比較して、使用時のクランプ圧を小さくすることができる(使用時クランプ圧<最大クランプ圧)ため、使用時に持ち手16,25同士を接触させる必要はない。 According to this experiment, as shown in FIG. 19, using the eyelash curler 1 having the maximum clamp pressure of 700 or more as shown in FIG. 16, the clamp pressure in actual use was set to about 500 which is the target value as shown in FIG. As the displacement amount, the displacement amount during use can be set to 14 mm. More specifically, in the eyelash curler 1, the clamp pressure during use can be reduced as compared with the clamp pressure (maximum clamp pressure: 744) that is displaced to the position where the handles 16, 25 in FIG. (Hour clamping pressure <maximum clamping pressure), so that there is no need to bring the handles 16, 25 into contact with each other during use.
 よって、第1実施形態のアイラッシュカーラー1では、使用時クランプ圧を、最大クランプ圧に対して変形量に余裕を持たせることが出来、部品に発生する応力を軽減できる。 Therefore, in the eyelash curler 1 of the first embodiment, the amount of deformation of the clamp pressure during use can be given a margin with respect to the maximum clamp pressure, and the stress generated in the parts can be reduced.
 このように、樹脂材料を選択して、断面係数を調整して構成することで、樹脂製でも、比較例の金属製のアイラッシュカーラーと同等のクランプ圧を実現することが可能であるとともに、そのクランプ圧を実現するためのグリップ力も金属製と近づけることができる。 In this way, by selecting a resin material and adjusting the cross-sectional coefficient to configure, it is possible to realize a clamping pressure equivalent to that of the metal eyelash curler of the comparative example even with resin, The grip force for realizing pressure can be made close to that of metal.
 ((実験例6))
 また、本発明者は、樹脂製のアイラッシュカーラー1を用いて、被験者による、まつ毛カール実験を行った。本実験において、3人の被験者を対象として、樹脂製のアイラッシュカーラー1の使用時圧力であるクランプ圧を測定した。
((Experimental example 6))
In addition, the present inventor performed an eyelash curl experiment by a subject using the eyelash curler 1 made of resin. In this experiment, the clamp pressure, which is the pressure during use of the resin eyelash curler 1, was measured for three subjects.
 図20は、樹脂製アイラッシュカーラー1の使用時のまつげクランプ圧を、ハンドメイド式測定器で測定した測定結果である。 FIG. 20 shows the result of measuring the eyelash clamp pressure when using the resin eyelash curler 1 with a hand-made measuring device.
 図20において、横軸は時間、縦軸はクランプ圧を示す。本実験においても、図6と同様に、アイラッシュカーラーの睫毛を挟む、クリッパーゴムの直下に圧力センサーを設置して、睫毛を挟む圧力のクランプ圧を測定した。 In FIG. 20, the horizontal axis represents time, and the vertical axis represents clamp pressure. In this experiment, as in FIG. 6, a pressure sensor was placed just below the clipper rubber between the eyelashes of the eyelash curler and the clamp pressure of the pressure between the eyelashes was measured.
 なお、図20(a)は、図6(a)に示す人物A、図20(b)は図6(b)に示す人物B,図20(c)は図6(c)に示す人物Cと同一人物である。 20A is a person A shown in FIG. 6A, FIG. 20B is a person B shown in FIG. 6B, and FIG. 20C is a person C shown in FIG. And the same person.
 図6と図20を比較すると、いずれの人物も、樹脂製のアイラッシュカーラー1では、図6での金属製アイラッシュカーラー9と同等またはそれ以上のクランプ圧を達成していることがわかる。したがって、アイラッシュカーラー1では、金属製のアイラッシュカーラー9とほぼ同じ使い方で、且つ同じような力の掛け方で、微調整しながらまつ毛のカールを実現することができる。 比較 Comparing FIG. 6 with FIG. 20, it can be seen that any person achieves the same or higher clamping pressure with the resin eyelash curler 1 as with the metal eyelash curler 9 in FIG. Therefore, in the eyelash curler 1, it is possible to realize curling of the eyelashes while performing fine adjustment by using the same method as the metal eyelash curler 9 and applying the same force.
 ((実験例7))
 また、第1実施形態の図11の寸法のアイラッシュカーラー1と、図15に示す比較例の金属製のアイラッシュカーラー9を用いた際のクランプ圧を、異なる装置で調査する実験を行った。
((Experimental example 7))
Further, an experiment was conducted in which the clamping pressure when using the eyelash curler 1 of the first embodiment having the dimensions of FIG. 11 and the metal eyelash curler 9 of the comparative example shown in FIG.
 本実験では、6人の被験者を対象として、図15に示す寸法の金属製のアイラッシュカーラー9を用いて、通常使用時と同様に使用してもらい、その際の使用時圧力であるクランプ圧を、後述の図26(a)に示すセンサーシート410で測定した。この際、まつ毛を挟む部分である、下側プレス部91の上に設置されるクリッパーゴムRの直下に、パソコン等の情報処理装置430と接続可能なセンサーシート410を挟んで、睫毛を挟む圧力のクランプ圧を測定した。 In this experiment, six test subjects were used to use the metal eyelash curler 9 having the dimensions shown in FIG. 15 in the same manner as in normal use, and the clamp pressure, which is the pressure during use, was used. The measurement was performed using a sensor sheet 410 shown in FIG. At this time, a pressure for pinching the eyelashes with the sensor sheet 410 connectable to the information processing device 430 such as a personal computer directly under the clipper rubber R installed on the lower press portion 91 which is a portion for pinching the eyelashes Was measured.
 図21に、金属製のアイラッシュカーラー9の、使用時の人によるまつげクランプ圧を、センサーシート410で測定した測定結果を示す。図21の(a)~(f)のグラフにおいて、縦軸はクランプ圧、横軸は時間(単位:秒)を示す。6人の被験者は、上述のA~Fとは異なる人物であって、人物G、人物H、人物I、人物J、人物K、人物Lとした。 FIG. 21 shows a measurement result obtained by measuring the eyelash clamp pressure by a human at the time of use of the metal eyelash curler 9 with the sensor sheet 410. In the graphs (a) to (f) of FIG. 21, the vertical axis represents the clamping pressure, and the horizontal axis represents time (unit: second). The six subjects were different from the above-mentioned A to F, and were set as a person G, a person H, a person I, a person J, a person K, and a person L.
 図21により、いずれの被験者も数回に分けてまつ毛をクランプすることがわかる。また、まつ毛のカールに要する全体の時間や回数、1回あたりのクランプ時間等は、個人差がある。 に よ り From FIG. 21, it can be seen that all the subjects clamp the eyelashes several times. In addition, the total time and number of times required for curling the eyelashes, the clamping time per one time, and the like vary from individual to individual.
 ここで、図21に示すように、各人のクランプ圧の最大値は、それぞれ、0.27、0.16、0.29、0.21、0.14、0.19(N:ニュートン)であった。 Here, as shown in FIG. 21, the maximum values of the clamping pressure of each person were 0.27, 0.16, 0.29, 0.21, 0.14, 0.19 (N: Newton), respectively.
 ((実験例8))
 図22は、6PA+GF65%樹脂で構成された第1実施形態のアイラッシュカーラー1の、使用時の人によるまつげクランプ圧を、センサーシート410で測定した測定結果である。
((Experimental example 8))
FIG. 22 shows a measurement result obtained by measuring the eyelash clamping pressure by the human eye when using the eyelash curler 1 of the first embodiment made of 6PA + GF65% resin using the sensor sheet 410.
 図22において、横軸は時間、縦軸はクランプ圧を示す。本実験においても、図21と同様に、アイラッシュカーラー1の睫毛を挟む、クリッパーゴムRの直下にセンサーシート410を挟んで、睫毛を挟む圧力のクランプ圧を測定した。 In FIG. 22, the horizontal axis represents time, and the vertical axis represents clamp pressure. Also in this experiment, similarly to FIG. 21, the clamp pressure of the pressure which clamps the eyelashes was measured by sandwiching the sensor sheet 410 directly under the clipper rubber R between the eyelashes of the eyelash curler 1.
 なお、図22において(a)~(f)は、図21(a)~(f)に示す人物G、人物H、人物I、人物J、人物K、人物Lとそれぞれ同一人物である。 In FIG. 22, (a) to (f) are the same persons as persons G, H, I, J, K, and L shown in FIGS. 21 (a) to 21 (f), respectively.
 ここで、図22に示すように、各人のクランプ圧の最大値は、それぞれ、0.26、023、0.24、0.19、0.14、0.25(N:ニュートン)であった。 Here, as shown in FIG. 22, the maximum values of the clamping pressure of each person were 0.26, 023, 0.24, 0.19, 0.14, 0.25 (N: Newton), respectively.
 図21と図22を比較すると、いずれの人物も、樹脂製の第2実施形態のアイラッシュカーラー1では、図21での金属製アイラッシュカーラー9と同等またはそれ以上のクランプ圧(まつげ挟み圧力)を達成していることがわかる。 Comparing FIG. 21 with FIG. 22, any person achieves a clamp pressure (eyelash pinching pressure) equal to or higher than the metal eyelash curler 9 in FIG. 21 in the resin-made eyelash curler 1 of the second embodiment. You can see that it is.
 したがって、第1実施形態のアイラッシュカーラー1では、金属製のアイラッシュカーラー9とほぼ同じ使い方で、且つ同じような力の掛け方で、微調整しながらまつ毛のカールを実現することができる。 Therefore, in the eyelash curler 1 of the first embodiment, it is possible to realize curling of the eyelashes while making fine adjustments by using the same method as the metal eyelash curler 9 and applying the same force.

FIG. 23 is a configuration diagram of an eyelash curler 2 according to the second embodiment of the present invention. FIG. 24 is an exploded view of the eyelash curler 2 according to the second embodiment of the present invention.
 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、及びの力点部材と作用部材との係合のヒンジ構成等が異なる。 In this embodiment, the material and the like are the same as the resin used in the first embodiment, but the hinge configuration of the engagement between the fixing member and the power point member and the engagement between the power point member and the action member are different. .
 図23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. 23, 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24に示すように、固定部材40において、アーム44に形成された係合穴部45において、幅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. 24, in the fixing member 40, a fulcrum shaft 48 for fitting that extends in the width direction is provided in an engagement hole 45 formed in the arm 44.
 そして、力点部材50の先端側アーム51が、持ち手55とは反対側の先端側の端部から、固定部材40の係合穴部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むこと、係合穴部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 engagement hole 45 of the fixing member 40 from the distal end side opposite to the handle 55, the power point member 50 is fixed to the fixing member 40. The force point member 50 and the fixing member 40 are connected by pushing down from above and engaging the fitting groove 53 with the fulcrum shaft 48 in the engagement hole 45.
 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を第2の支点(図4の支点B)として、力点部材50が固定部材40に対して回動自在に連結する。 The fulcrum shaft 48 of the fixing member 40 fitted in the fitting groove 53 of the fulcrum member 50 is used as a second fulcrum (the fulcrum B in FIG. 4), and the fulcrum member 50 is rotatably connected to the fixing member 40. I do.
 なお、図24においては、支点軸48は係合穴部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、係合穴部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. 24 shows an example in which the fulcrum shaft 48 extends in the entire width direction of the engagement hole 45. However, the fulcrum shaft 48 that can be fitted in the fitting groove 53 is provided in the engagement hole portion. It may be a double-sided projecting shape that protrudes from the inner side surface of the forty-fifty-five and has a broken central portion.
 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。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。 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. 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とが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. As described above, the fitting hook 52 of the power point member 50 and the fitting tube 63 of the operation member 60 are fitted, so that the operation member 60 can move in conjunction with 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4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4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. 4) and the connection between the power point member 50 and the operating member 60 (the first fulcrum A in FIG. 4) are formed in the hook shape. 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、ピン軸PS1,PS2を用いることなく、第2実施形態のアイラッシュカーラー2は、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, the eyelash curler 2 of the second embodiment can realize a completely metal-free engagement portion of the components without using the pin shafts PS1 and PS2 for connecting the members in the first embodiment. .
 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2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。 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 2 is contaminated, it is possible to disassemble and clean the eyelash curler 2, whereby it is possible to clean even small irregularities of the engaging portion, and thereafter, it is possible to assemble.
 さらに、例えば、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と第2の支点Bでは係合の方向が反対方向であるため、一方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。 Furthermore, even if a load is suddenly applied, for example, in a makeup pouch or luggage, destruction can be avoided by releasing the hook. At this time, since the direction of engagement between the first fulcrum A and the second fulcrum B is opposite, when a strong force is applied in one direction, either the first fulcrum A or the second fulcrum B is applied. Since only the engagement state 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の先端部には、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、延伸部(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。 A fitting hook 52 having a concave upper side is provided at the distal end of the distal arm 51 of the power point member 50, and a lower concave fitting is provided at a portion closer to the distal end than the handle 55 of the distal arm 51. A mating groove 53 is formed, and the extending portions (second arm portions) 51 and 54 extend from the tip to the handle 55 by one.
 そのため、本実施形態のアイラッシュカーラー2においても、第1実施形態同様に、金属製と異なり、持ち手の部分を、延伸部(アーム部)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 2 of the present embodiment, similarly to the first embodiment, unlike the case of metal, the handle portion can be made as thick as the extending portion (arm portion). Can also improve the holdability.
 力点部材50の後端側アーム54において、嵌合溝53よりも第2の持ち手55に近い部分であって、上側の面には、波打ち状に凹凸が形成されている。 In the rear end arm 54 of the force point member 50, a portion closer to the second handle 55 than the fitting groove 53, and an upper surface is formed with wavy irregularities.
 この波打ち状の凹凸形状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の指孔には親指を入れ、力点部材50側の持ち手55の指孔には、他の指を入れる。最も力が入りやすい中指を持ち手55の指孔に入れた場合、あるいは薬指を指孔に入れた場合、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。 (4) The undulating irregularities 541 and 542 improve the fit. In particular, when applying 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 forefinger or the middle finger also supports the power point member 50 due to the uneven shapes 541 and 542, and the operation is performed. Becomes stable.
 また、持ち手55のさらに後端には、指掛け部56が設けられている。例えば、使用者が自分で自分のまつ毛をカールする際、力点部材50側の持ち手55の指孔には中指を入れ、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の指孔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の指孔には薬指を入れ、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 portion 56 is provided. For example, when the user curls his or her own eyelashes, 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 on the power point member 50 side is used. The index finger is inserted into the finger hole 55, the middle finger is inserted into the finger hook portion 56, or the ring finger is inserted into the finger hole of the handle 55 on the power point member 50 side, and the little finger is inserted into the finger hook portion 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、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, when the eyelashes are curled to support the emphasis member 50 with the concave and convex shapes 541 and 542 and the finger hook portion 56 except for the finger put in the finger hole of the handle 55. In addition, the burden on one finger at the time of push is shared, and the operation is stabilized.
 また、固定部材40の第1の持ち手46及び力点部材50の第2の持ち手55を閉じた際に対向する部分には、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 first handle 46 of the fixing member 40 and the second 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、固定部材に対する力点部材の過剰な回転を防止する。 (4) When pressing the eyelashes, the tips of the hit points 47, 57 of the handles 46, 55 abut against each other, thereby preventing excessive rotation of the power point member with respect to the fixing member.
 なお、持ち手の内側にヒットポイント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ゴム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、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 inside the handle, for example, when the rubber is crushed and thinned by repeated use, the clamp pressure of the press portion when the rubber is pushed in is insufficient. It may disappear. Therefore, when setting the hit points 47 and 57, it is preferable to set the length and the like including the case where the rubber is crushed.
 <第2実施形態と解析>
 ((実験例9))
 図25は、第2実施形態のアイラッシュカーラー2の寸法例を示す図である。構成の一例として、第2実施形態のアイラッシュカーラー2において、図25で示した下記寸法で設計した。
固定部材40の応力発生範囲の断面係数Z=16.88mm3
力点部材50の応力発生範囲であるアーム部54の断面係数Z=16.875mm3
<Second embodiment and analysis>
((Experimental example 9))
FIG. 25 is a diagram illustrating a dimension example of the eyelash curler 2 of the second embodiment. As an example of the configuration, the eyelash curler 2 of the second embodiment was designed with the following dimensions shown in FIG.
Section modulus Z of the stress generation range of the fixing member 40 is 16.88 mm 3.
The section modulus Z of the arm portion 54, which is the stress generation range of the power point member 50, is equal to 16.875 mm 3.
 なお、本構成では、アーム部54が外側に指を置くための凹凸を有しているため、この断面係数は、最も厚さが薄い部分の断面係数に相当する。
また、支点B周辺のアーム部51は、荷重点側の最も薄い部分よりは分厚く、その断面係数Z=17.63mm3
作用部材60の断面係数Z=1.725mm3
In this configuration, since the arm portion 54 has irregularities for placing a finger on the outside, the section coefficient corresponds to the section coefficient of the thinnest portion.
Further, the arm portion 51 around the fulcrum B is thicker than the thinnest portion on the load point side, and its section modulus Z = 17.63 mm 3
Section modulus Z of the acting member 60 = 1.725 mm 3
 図26は、装置により徐々に変化する荷重を与えてグリップ力、クランプ圧を測定するためのセンサーシートによる測定機構及び第2の試験機による荷重位置を示す図である。 FIG. 26 is a diagram showing a measurement mechanism using a sensor sheet for measuring a grip force and a clamping pressure by giving a load that gradually changes by the device, and a load position by the second tester.
 図26に示す第2の測定環境では、グリップ力(図27)の測定の際には、第1の試験機と異なる試験機を用いた。 で は In the second measurement environment shown in FIG. 26, a different testing machine from the first testing machine was used for measuring the grip force (FIG. 27).
 第2の測定環境では、試験機は、アイラッシュカーラー1,9に対して、図26(b)に示すように、持ち手16を下側にした状態で固定し、持ち手25(55、85)の指穴の中側から荷重を加えている。 In the second measurement environment, the testing machine fixes the eyelash curlers 1 and 9 with the handle 16 down as shown in FIG. 26B, and the handle 25 (55, 85). The load is applied from the inside of the finger hole.
 また、クランプ圧(図28)の測定の際には、図26(a)に示すように、アイラッシュカーラー1(2、9)の睫毛を挟むための、クリッパーゴムRの直下に、センサーシート410を設置して、図26(b)に示す位置に、第2の試験機により変化する荷重を与えた際の、挟む圧力を測定した。 When measuring the clamp pressure (FIG. 28), as shown in FIG. 26 (a), the sensor sheet 410 is placed immediately below the clipper rubber R for pinching the eyelashes of the eyelash curler 1 (2, 9). The test piece was installed and a pinching pressure was measured when a load changed by the second testing machine was applied to the position shown in FIG. 26 (b).
 なお、センサーシート410の他端は、センサコネクタ420を介して、情報処理装置430に接続されている。そのため、下側プレス部31(61、91)の溝部のクリッパーゴムRの直下に設置したセンサーシート410は、第2の測定機により変化する荷重を与られた際に、上側プレス部11及びクリッパーゴムRにより下側プレス部31を押す圧力(挟み込み圧力)を測定して、センサコネクタ510を介して、情報処理装置430へ自動的にデータを送信する。なお、図26(a)に示すセンサーシート410は、上述の図21、図22で人の手による挟みこみを測定する際と同じものを用いた。 The other end of the sensor sheet 410 is connected to the information processing device 430 via the sensor connector 420. For this reason, the sensor sheet 410 installed immediately below the clipper rubber R in the groove of the lower press portion 31 (61, 91) receives the upper press portion 11 and the clipper when the load changed by the second measuring machine is applied. The pressure (pinching pressure) of pressing the lower press unit 31 by the rubber R is measured, and the data is automatically transmitted to the information processing device 430 via the sensor connector 510. The sensor sheet 410 shown in FIG. 26A is the same as that used for measuring the pinching by a human hand in FIGS. 21 and 22 described above.
 図26に示す第2の測定環境では、図26(b)に示すように持ち手25(55、85)の指穴の中側から荷重を加えているため、荷重を印加する位置は、図4で示す荷重点Cにほぼ近い位置である。 In the second measurement environment shown in FIG. 26, the load is applied from the inside of the finger hole of the handle 25 (55, 85) as shown in FIG. 26 (b). 4 is a position almost close to the load point C.
 この荷重の位置により、第2の測定環境では、図14に示す第1の測定環境よりも、さらに人による使用の状態に近づけて、アイラッシュカーラー1(2、9)に対して荷重を付加して、グリップ力、クランプ圧を測定することができる。 Due to the position of the load, in the second measurement environment, a load is applied to the eyelash curler 1 (2, 9) in a manner closer to the state of use by a person than in the first measurement environment shown in FIG. , Grip force and clamp pressure can be measured.
 図27は、金属製、6PA+GF65%樹脂で構成された第1実施形態、6PA+GF65%樹脂で構成された第2実施形態、PAMXD6+GF50%樹脂で構成された第2実施形態の、4種類のアイラッシュカーラーの持ち手の荷重点に加えたグリップ力(荷重)を、図26に示す測定環境で測定した際の測定結果である。PAMXD6は、ポリアミドMXD6を意味する。 FIG. 27 shows four types of the first embodiment made of metal, 6PA + GF65% resin, the second embodiment made of 6PA + GF65% resin, and the second embodiment made of PAMXD6 + GF50% resin. 26 is a measurement result when the grip force (load) applied to the load point of the handle of the eyelash curler is measured in the measurement environment shown in FIG. PAMXD6 means polyamide MXD6.
 なお、第2実施形態については、6PA+GF65%樹脂、PAMXD6+GF50%樹脂のいずれの樹脂を用いた場合でも、図25で示す寸法例のアイラッシュカーラー2の形状を用いた。 In the second embodiment, the shape of the eyelash curler 2 of the dimension example shown in FIG. 25 was used regardless of whether 6PA + GF65% resin or PAMXD6 + GF50% resin was used.
 また、第2の測定環境では、図26(b)に示すように、アイラッシュカーラー1(2、9)に対して、持ち手25(55、85)の指穴内側から荷重を加える際、測定対象の4種類のアイラッシュカーラー1(2、9)に対して、荷重点Cの位置をヒンジ部(図4の支点B)より50mmの位置に統一した。これにより、4種類のアイラッシュカーラー9,1,2において、支点Bから荷重点Cまでの距離は等しくなる。 In the second measurement environment, as shown in FIG. 26B, when a load is applied to the eyelash curler 1 (2, 9) from the inside of the finger hole of the handle 25 (55, 85), For the four types of eyelash curlers 1 (2, 9), the position of the load point C was unified to a position 50 mm from the hinge portion (the fulcrum B in FIG. 4). As a result, the distance from the fulcrum B to the load point C is equal in the four types of eyelash curlers 9, 2, 1.
 この設定により、アイラッシュカーラー9、1、2の形状の違いによる、支点Bから荷重点Cまでの距離の違いに起因する、測定値のズレをほとんど無くすことができる。 With this setting, it is possible to almost eliminate the deviation of the measured values due to the difference in the distance from the fulcrum B to the load point C due to the difference in the shape of the eyelash curlers 9, 1, 2.
 図27に示すように、同じ変位量動かした場合、第1実施形態、6PA+GF65%樹脂で構成された第2実施形態、PAMXD6+GF50%樹脂で構成された第2実施形態のアイラッシュカーラー1,2は、金属製のアイラッシュカーラー9に対しては少し足りないが、ほぼ同じ、グリップ力を有している。 As shown in FIG. 27, when moved by the same amount of displacement, the eyelash curlers 1 and 2 of the first embodiment, the second embodiment composed of 6PA + GF65% resin, and the second embodiment composed of PAMXD6 + GF50% resin Although the metal eyelash curler 9 is slightly insufficient, it has almost the same grip force.
 図28は、金属製、6PA+GF65%樹脂で構成された第1実施形態、6PA+GF65%樹脂で構成された第2実施形態、PAMXD6+GF50%樹脂で構成された第2実施形態の、4種類のアイラッシュカーラーのクランプ圧を、図26に示す測定環境で測定した際の測定結果である。 FIG. 28 shows four types of the first embodiment made of metal, 6PA + GF65% resin, the second embodiment made of 6PA + GF65% resin, and the second embodiment made of PAMXD6 + GF50% resin. 26 is a measurement result when the clamp pressure of the eyelash curler is measured in the measurement environment shown in FIG.
 図28に示すように、同じ変位量動かした場合、第1実施形態、6PA+GF65%樹脂で構成された第2実施形態、PAMXD6+GF50%樹脂で構成された第2実施形態のアイラッシュカーラー1,2は、金属製に対しては少し足りないが、ほぼ同じ、クランプ圧を有している。 As shown in FIG. 28, when moved by the same displacement, the eyelash curlers 1 and 2 of the first embodiment, the second embodiment composed of 6PA + GF65% resin, and the second embodiment composed of PAMXD6 + GF50% resin It has almost the same clamping pressure, but slightly less than metal.
 ((実験例10))
 金属製のアイラッシュカーラー9と、6PA+GF65%樹脂で構成された第1実施形態のアイラッシュカーラーのクランプ圧を、図17に示す第1の測定環境と、図26に示す測定環境との両方で、測定し、測定環境の整合性を確認した。
((Experimental example 10))
The clamp pressure of the eyelash curler 9 made of metal and the eyelash curler of the first embodiment composed of 6PA + GF65% resin was measured in both the first measurement environment shown in FIG. 17 and the measurement environment shown in FIG. Then, the consistency of the measurement environment was confirmed.
 図17に示す第1の測定環境下で測定したクランプ圧のデータと、図26に示す第2の測定環境下で測定したクランプ圧のデータの換算について、それぞれの測定値の比をとることにより、相関性を出した。図29は、その相関表である。 The conversion between the data of the clamp pressure measured under the first measurement environment shown in FIG. 17 and the data of the clamp pressure measured under the second measurement environment shown in FIG. And gave a correlation. FIG. 29 is the correlation table.
 第1の測定環境のデータ(旧測定値)を、第2の測定環境のデータ(新測定値)に変換するには、測定値の誤差も考慮して、旧測定値に0.03%~0.05%の数値を乗算する。これにより、無単位の旧測定値を新測定値の圧力単位(MPa)に変換できる。 In order to convert the data of the first measurement environment (old measurement value) to the data of the second measurement environment (new measurement value), the error of the measurement value is also taken into consideration, and the old measurement value is changed from 0.03% to 0.05%. Multiplies the numbers. As a result, the old measured value without any unit can be converted into the pressure unit (MPa) of the new measured value.
 これにより、図17に示す第1の測定環境によるデータと、図26に示す第2の測定環境によるデータは相互に関連し、誤差が少ないことがわかる。 This shows that the data in the first measurement environment shown in FIG. 17 and the data in the second measurement environment shown in FIG. 26 are related to each other and have a small error.
 また、図21、図22の実使用時のセンサーシート410を用いたクランプ圧と、図28の測定のセンサーシート410を用いたクランプ圧とを比較すると、図21、図22の実使用時は、図28における最大値である13mm変位時と同程度、あるいは、13mm変位時よりも少し多く変位させている。これにより、第1実施形態のアイラッシュカーラー2は、13mm又は13mmより少し多く変位させることで、所望のクランプ圧を実現し、まつ毛を持ち上げることができる。 In addition, comparing the clamp pressure using the sensor sheet 410 in actual use in FIGS. 21 and 22 with the clamp pressure using the sensor sheet 410 in the measurement in FIG. 28, the actual use in FIGS. 28, the displacement is approximately the same as that at the time of displacement of 13 mm, which is the maximum value in FIG. 28, or slightly more than at the time of displacement of 13 mm. Thereby, the eyelash curler 2 of the first embodiment can realize a desired clamping pressure and lift the eyelashes by displacing the eyelash curler slightly by 13 mm or slightly more than 13 mm.
 また、前述の図28に示すように、第2実施形態のアイラッシュカーラー2によるクランプ圧は第1実施形態のアイラッシュカーラー1と、同程度のクランプ圧があることから、アイラッシュカーラー2も金属と同程度のレベルと予想できる。 Further, as shown in FIG. 28, the clamp pressure by the eyelash curler 2 of the second embodiment has the same clamp pressure as that of the eyelash curler 1 of the first embodiment. Can be expected.
 上記実験からわかるように、本実施形態のアイラッシュカーラー2においても、図10に示した断面係数とヤング率で規定された推奨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と予想できる。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。 As can be seen from the above experiment, also in the eyelash curler 2 of the present embodiment, by using a resin falling within the recommended range defined by the section modulus and the Young's modulus shown in FIG. Thus, it can be expected that equivalent stress can be realized. 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.
 <部分用アイラッシュカーラー>
 なお、上記の第1、第2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>
Although the first and second embodiments have been described on the premise that the eyelash curler of the whole area type is close to the entire width of the eyes, sandwiches the entire eyelashes, the eyelash curler of the present invention having the above-mentioned material and cross-sectional shape is partially Eyelash curler may be used.
 例えば、部分用アイラッシュカーラー3は、図30に示すように、上述の第1実施形態又は第2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又は下側プレス部31Pの幅が短い構成であってもよい。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。 For example, as shown in FIG. 30, the partial eyelash curler 3 has a configuration similar to that of the first embodiment or the second embodiment described above, and the width of the upper press portion 11P or the lower press portion 31P sandwiching the eyelashes is reduced. A short configuration may be used. 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.
 あるいは、図31に示すように、ピンセットタイプの部分用アイラッシュカーラー4であってもよい。 Alternatively, as shown in FIG. 31, a tweezers-type partial eyelash curler 4 may be used.
 部分用アイラッシュカーラー3,4において、図10に示した断面係数とヤング率で規定された推奨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ため、金属製と同等の、まつ毛カール効果を発揮できる。 In the partial eyelash curlers 3 and 4, by using a resin falling within the recommended range defined by the section modulus and the Young's modulus shown in FIG. 10, the same bending can be realized as that of a metal and the same stress can be realized by a clamping pressure. Therefore, the same eyelash curl effect as that of metal can be exhibited.
 なお、図30に示す部分用アイラッシュカーラー3,4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少し小さくてもよい。 In the partial eyelash curlers 3 and 4 shown in FIG. 30, since the required force is smaller than that of the whole type, if the material satisfies the Young's modulus of the recommended range described above, the section modulus defining the thickness is slightly smaller than the recommended range. You may.
