Abstract

The present invention provides a pierced-earring catch in which a pin nip force at a pin nip part does not increase when the pierced-earring catch is pinched and removed from a pierced-earring pin. Even if the pinching force is significantly increased, only an upper soft structural part is flattened and deformed. Hence, there is almost no influence on a first nip part 6a and a second nip part 6b, where a pin nip portion 6c inside a lower stiff structural part is positioned below a finger contact section 11. Hence, an urging nip force of the pin nip part 6c hardly increases, and no significant resistance to a removal operation from the pin is produced.

The catch <A> is composed of a resin elastic body <9>, and a metal spring member <1> provided in the resin elastic body <9> by integral molding by injection molding or the like. Yes.
 樹脂製弾性体<9>は、上部側を上側湾曲凸部<d>とし、下部側を下側湾曲凸部<e>とし、上側湾曲凸部<d>と下側湾曲凸部<e>の間に凹湾曲形態で連絡してなる環状凹部<11>を形成している。

The elastic body <9> made of resin has an upper curved convex portion <d> on the upper side, a lower curved convex portion <e> on the lower side, an upper curved convex portion <d> and a lower curved convex portion <e>. An annular recess <11> is formed which is communicated in the form of a concave curve.
The spring member <1> is curled in a curved manner from the metal substrate <3> having a pin hole <5> through which the pin <7> passes in the center, and the left and right sides of the substrate <3>.

An insertion hole <10> is formed. The pin <7> inserted into the pin insertion hole <10> is clamped at a pin clamping location <4c> between the first curved portion <4a> and the second curved portion <4b>. The curved portion <4> is a metal material that is relatively hard and hardly deformed.
 ピン<7>がピン挿入穴<10>に挿入されると、第1の湾曲部<4a>と第2の湾曲部<4b>はピン<7>によって外側に押され動く。このとき樹脂製弾性体<9>の弾性反発力が第1の湾曲部<4a>と第2の湾曲部<4b>に働くため、ピン挿入穴<10>に挿入されたピン<7>は、硬い第1の湾曲部<4a>と第2の湾曲部<4b>のピン挟持箇所<4c>で強めに挟持される。樹脂製弾性体<9>の底部材である基板<3>には、ピン<7>をピン挿入穴<10>に導入するためのすり鉢状の凹部<12>が形成されている。 When the pin <7> is inserted into the pin insertion hole <10>, the first curved portion <4a> and the second curved portion <4b> are pushed outward by the pin <7> and moved.

特許第5041748号公報Japanese Patent No. 5041748
 以下に、樹脂製弾性体<9>を、第1の湾曲部<4a>(第1の挟持部)と第2の湾曲部<4b>(第2の挟持部)の側方(図13では右側と左側)から、親指と人差指で摘んだ場合に生じる状態について述べる(図13参照)。 Hereinafter, the elastic body <9> made of resin is placed on the sides of the first curved portion <4a> (first clamping portion) and the second curved portion <4b> (second clamping portion) (in FIG. 13). A state that occurs when the thumb and index finger are picked from the right side and the left side will be described (see FIG. 13).
 ≪キャッチ<A>≫
 ピン<7>がピン挿入穴<10>に挿入されているピン挿入状態の樹脂製弾性体<9>を、親指と人差指で摘み(以下「摘み」、「摘む」、「摘んで」ないし「摘んだ」等という。)、該ピン<7>から抜くピンからの抜き操作時の、該樹脂製弾性体<9>の摘み形態は以下の通りである。
≪Catch <A> ≫
The pin elastic state <9> with the pin <7> inserted into the pin insertion hole <10> is picked with the thumb and index finger (hereinafter referred to as “pick”, “pick”, “pick” or “pick”). The pinching form of the resin elastic body <9> at the time of pulling out from the pin <7> is as follows.
 キャッチ<A>が小キャッチでは5.4mm×4.0mm、大キャッチでは6.7mm×5.0mmと小さいため、摘んだ指の両指先は下側湾曲凸部<e>の下部側を下方に越えて摘んだ状態である下側凸部指掛かり摘み形態となるものである。この下側凸部指掛かり摘み形態となる理由は、(ア)下側湾曲凸部<e>の下部角(下部縁)が小キャッチでは半径(R)1.0mm、大キャッチでは半径(R)0.9mmと大きく湾曲した湾曲下部角であり、(イ)上側湾曲凸部<d>と下側湾曲凸部<e>とが同じ太さで、(ウ)環状凹部<11>の上下幅が1.1mmないし1.3mmと狭く、(エ)環状凹部<11>と上側湾曲凸部<d>および下側湾曲凸部<e>の連絡が滑らかな湾曲連絡形態であり、(オ)摘み指からみて上下距離が4mm~5mmと小さい形態の樹脂製弾性体<9>は、摘む指に対して実質的には湾曲下部角形態のストレート構造体であるためである。 Since the catch <A> is as small as 5.4 mm x 4.0 mm for the small catch and 6.7 mm x 5.0 mm for the large catch, both fingertips of the picked fingers are below the lower curved convex part <e>. The lower convex portion is in a state of being picked over the top and is in a pinching form. The reason for this lower convex finger gripping configuration is that (a) the lower corner (lower edge) of the lower curved convex portion <e> has a radius (R) of 1.0 mm for a small catch, and a radius (R) for a large catch. (B) The upper curved convex part <d> and the lower curved convex part <e> have the same thickness, and (c) the upper and lower parts of the annular concave part <11>. The width is as narrow as 1.1 mm to 1.3 mm, and (d) the ring-shaped concave portion <11> is smoothly connected to the upper curved convex portion <d> and the lower curved convex portion <e>. This is because the resin-made elastic body <9> whose vertical distance is as small as 4 mm to 5 mm when viewed from the picking finger is a straight structure substantially having a curved lower corner with respect to the finger to be picked.
 湾曲下部角形態のストレート構造体の4mm~5mmの小さなキャッチ<A>を摘む場合、樹脂製弾性体<9>が指から抜けないようにするために、最も指掛かりが大きい箇所である下側湾曲凸部<e>の最大突出部位よりも下方の内向き傾斜面に、指先が強くかかるような摘み動作とならざるを得ないものでもある。このようにキャッチ<A>からピンを抜く際には、下側湾曲凸部<e>の下部の内向き傾斜部分に指先が強くかかった状態でキャッチ<A>を保持することにより、ピアスピンを抜く操作を容易に行うことができる。 When picking a small catch <A> of 4 to 5 mm in a straight structure with a curved lower corner, the lower side where the finger hold is the largest to prevent the resin elastic body <9> from coming off the finger This is also a pinching operation in which the fingertip is strongly applied to the inwardly inclined surface below the maximum projecting portion of the curved convex portion <e>. Thus, when pulling out the pin from the catch <A>, by holding the catch <A> with the fingertip strongly applied to the inwardly inclined portion of the lower part of the lower curved projection <e>, The pulling operation can be easily performed.
 上側湾曲凸部<d>は、小キャッチでは半径(R)0.9mm、大キャッチでは半径(R)1.0mmという肉厚で鈍角の無い緩やかな湾曲突起形態である。このような肉厚で緩やかな湾曲の湾曲突起形態は、指の摘まみ力を強めても潰れ変形が小さく、かつ、上方に反り逃げるような変形は緩やかな湾曲による滑りも加わって殆ど生じないものである。よって、指も上方への逃げが生じることがなく、よってフィット感が悪く下側湾曲凸部<e>およびバネ部材<1>(ピン挟持硬質体)の位置に指が位置して、それを強く摘まむことになるものである。 The upper curved convex portion <d> is a gently curved projection with a wall thickness of radius (R) 0.9 mm for a small catch and radius (R) 1.0 mm for a large catch and no obtuse angle. Such a thick and gently curved curved protrusion form has little crushing deformation even when the finger picking force is increased, and deformation that warps upward and escapes hardly occurs due to slippage due to gentle bending. Is. Therefore, the finger also does not escape upward, so that the fit is poor and the finger is positioned at the position of the lower curved convex portion <e> and the spring member <1> (pin clamping hard body). It will be picked strongly.
 したがって、摘んだ指の摘み力を強めると、上側軟らかめ構造部位(上側湾曲凸部<d>)部位はほんのわずか潰れ変形し、下側硬め構造部位(環状凹部<11>と下側湾曲凸部<e>)は上側湾曲凸部<d>の変形よりは小さな変形ないし殆ど変形しないものとなる。そのまま、摘み力を強めると当然キャッチ<A>は指から押し出されて行く動き(指から抜ける動き)となる。 Therefore, when the picking force of the picked finger is increased, the upper soft structure portion (upper curved convex portion <d>) portion is slightly crushed and deformed, and the lower stiffened structural portion (annular concave portion <11> and lower curved convex portion is formed. The portion <e>) is smaller or hardly deformed than the upper curved convex portion <d>. If the picking power is increased as it is, naturally the catch <A> is pushed out from the finger (moving out of the finger).
 この押し出されて行く動きを止めるためには、下側硬め構造部位(特に下側湾曲凸部<e>)側を強く摘み、該下側湾曲凸部<e>の下部側に指肉を回し込む摘み動作になる。そして、下側硬め構造部位(特に下側湾曲凸部<e>)側を強く摘むと、そこの内側に位置しているバネ部材<1>への両側部側からの押力が強まり、上側湾曲凸部<d>と下側湾曲凸部<e>のピン挟持箇所<4c>のピン挟持力が著しく強まり、ピンからの抜く操作抵抗が著しく強まってしまうピン挟持力増強動作となるものである。 In order to stop the pushed-out movement, the lower stiff structure portion (particularly, the lower curved convex portion <e>) is strongly picked, and the finger is turned to the lower side of the lower curved convex portion <e>. It becomes a picking operation. And if the lower stiff structure part (especially lower curved convex part <e>) side is picked strongly, the pushing force from the both side parts to the spring member <1> located inside will become strong, This is a pin clamping force increasing operation in which the pin clamping force of the pin clamping portion <4c> of the curved convex portion <d> and the lower curved convex portion <e> is remarkably increased, and the operation resistance pulled out from the pin is remarkably increased. is there.
 キャッチ<A>は4mm~5mmと小さく、キャッチを摘んでピンを抜く操作においては、環状凹部<11>は上下の幅が狭くかつ湾曲角が小キャッチでは半径(R)0.9mm、大キャッチでは半径(R)1.0mmという鈍角の無い上側湾曲凸部<d>との緩やかな湾曲連絡であるため、上側湾曲凸部<d>への指の掛かりが弱い。よって、上側湾曲凸部<d>は指肉が掛かる指掛かり部位(爪掛かりを除く)としての機能は弱いものである。 The catch <A> is as small as 4 to 5 mm, and in the operation of picking the catch and pulling out the pin, the annular recess <11> has a radius (R) of 0.9 mm for a catch with a narrow top and bottom width and a small bending angle. Then, since it is a gentle curved contact with the upper curved convex portion <d> having an obtuse angle with a radius (R) of 1.0 mm, the finger is not easily hooked on the upper curved convex portion <d>. Therefore, the upper curved convex portion <d> has a weak function as a finger hook portion (excluding the nail hook) where the finger meat is applied.
 また、下側湾曲凸部<e>の下部面に指を掛けないで摘んだ場合、または上側湾曲凸部<d>、環状凹部<11>および下側湾曲凸部<e>の側部面のみに指を掛けて摘んだ場合には、摘む力を強めるとキャッチ<A>が容易に指から滑り抜け落ちてしまうものである。 Further, when picked without placing a finger on the lower surface of the lower curved convex portion <e>, or side surfaces of the upper curved convex portion <d>, the annular concave portion <11>, and the lower curved convex portion <e> In the case of picking with only a finger, the catch <A> easily slips off from the finger when the picking force is increased.
 また、キャッチ<A>は、硬質部材であるバネ部材<1>を樹脂製弾性体<9>の胴部に位置させた形態であり、かつ、バネ部材<1>の最上部位置が、環状凹部<11>の最上部位置から下方に小キャッチでは0.25mm、大キャッチでは0.27mm(弾性構造体胴部)と極めて狭い配置とされている。このため、環状凹部<11>(弾性構造体胴部)は全体が、バネ部材<1>による硬めの構造となっており、かつ、バネ部材<1>位置する下側湾曲凸部<e>も硬め構造部位となっている。 The catch <A> is a form in which the spring member <1>, which is a hard member, is positioned on the body of the resin elastic body <9>, and the uppermost position of the spring member <1> is annular. From the uppermost position of the recess <11>, the small catch is 0.25 mm and the large catch is 0.27 mm (elastic structure body), which is an extremely narrow arrangement. For this reason, the annular recess <11> (elastic structure body) as a whole has a hard structure by the spring member <1>, and the lower curved convex portion <e> located in the spring member <1>. Is also a harder structural part.
 すなわち、硬質のバネ部材<1>が位置する環状凹部<11>および下側湾曲凸部<e>は下側硬め構造部位を形成し、バネ部材<1>の配置の無い上側湾曲凸部<d>部位は上側軟らかめ構造部位を形成し、かつ、上側軟らかめ構造部位の下側硬め構造部位に連絡する部位である、バネ部材<1>の最上部位置と環状凹部<11>の最上部位置(=上側湾曲凸部<d>の最下部位置)のキャッチ離れ区間は、小キャッチでは0.25mm、大キャッチでは0.27mmという狭いキャッチ離れ距離であるものである。 That is, the annular concave portion <11> where the hard spring member <1> is located and the lower curved convex portion <e> form a lower rigid structural portion, and the upper curved convex portion <where the spring member <1> is not disposed < The d> part forms the upper soft structure part and is the part that communicates with the lower hard structure part of the upper soft structure part and the uppermost position of the spring member <1> and the uppermost part of the annular recess <11>. The catch separation section at the upper position (= the lowermost position of the upper curved convex portion <d>) has a narrow catch separation distance of 0.25 mm for the small catch and 0.27 mm for the large catch.
 このため、キャッチ<A>は、狭いそのキャッチ離れ区間は摘まみ力によって伸びることは殆んど無いないものであり、かつ、上側湾曲凸部<d>の上方逃げ変形が生じ難いことによって、指の摘み力強め操作では下側硬め構造部位も強く摘まむことになり、ピン挟持箇所<4c>のピン挟持力が著しく強まってしまうピン挟持力増強動作になるものである。 For this reason, the catch <A> is such that the narrow catch separation section is hardly stretched by the picking force, and the upper curved convex portion <d> is less likely to cause upward escape deformation, In the operation of strengthening the pinching force of the finger, the lower stiff structure portion is also strongly picked, and the pin pinching force increasing operation in which the pin pinching force of the pin pinching portion <4c> is remarkably increased is performed.
 また、キャッチ<B>に関して、特許文献1の段落[0018]において、「ピン<7>を受ける際には、キャッチの外周に形成されている環状凹部<11>を指先や爪の先で摘むことができる」と記載されている。しかし、実際には下側湾曲凸部<e>の下部面に指を掛けず、指先(指先肉)を環状凹部<11>に位置させて摘まもうとしても、摘み力を強めると即指から滑り抜け落ちるため、指肉での摘みではピンを抜く操作がし難いものである。 Regarding the catch <B>, in paragraph [0018] of Patent Document 1, “when receiving the pin <7>, the annular recess <11> formed on the outer periphery of the catch is pinched with the tip of a fingertip or nail. Is possible. " However, in fact, even if an attempt is made to place a fingertip (fingertip meat) in the annular recess <11> without placing a finger on the lower surface of the lower curved projection <e>, if the picking force is increased, Because it slips down, it is difficult to remove the pin by finger picking.
 これに対し、親指爪と人差指爪を環状凹部<11>に入れて摘むと、比較的しっかりとキャッチを摘むことができ、容易に抜き操作を行うことができる。よって、キャッチ<A>、<B>ともに、環状凹部<11>は「爪掛かり部」ないし「爪摘み部」として機能するものであり、指肉に掛かる「指摘み部」としては機能しないものであるとするのが相当であるものである。 On the other hand, when the thumb nail and the index finger nail are put in the annular recess <11> and picked, the catch can be picked relatively firmly and the pulling operation can be easily performed. Therefore, in both the catches <A> and <B>, the annular recess <11> functions as a “nail catching part” or “nail picking part” and does not function as an “pointing part” on the finger meat. It is a considerable thing to be.
 爪が長い人、爪に付けたネイルが長い人は、指先や爪で摘むことが難しいので、通常は、爪同士が当たらない親指と人差指の横腹部位同士で摘む指横腹部位摘み形態(図5の図(b)参照)にして、ピンからの着脱操作をおこなっている。かかる指横腹部位摘み形態では、キャッチ<A>、<B>は前述したように摘み力を強めると指から押し出され抜け落ちてしまう。 People with long nails and people with long nails attached to the nails are difficult to pick with their fingertips and nails, so the finger flank part is usually picked between the thumb and index finger flank parts (FIG. 5). (See (b) in FIG. 4), and the attachment / detachment operation from the pin is performed. In such a finger flank portion picking form, the catches <A> and <B> are pushed out of the finger and fall off when the picking force is increased as described above.
 ≪キャッチ<B>について≫
 特許文献1のキャッチ<B>では、第1の湾曲部<4a>および第2の湾曲部<4b>の上下方向のほぼ中心位置にある挟持箇所<4c>は、環状凹部<11>の中心位置<C>とほぼ同じ位置にある。また、第1の湾曲部<4a>および第2の湾曲部<4b>の最上部であるバネ部材<1>の最上部は環状凹中心位置<C>より上方に位置している。
≪About Catch <B> ≫
In the catch <B> of Patent Document 1, the sandwiched portion <4c> at the substantially vertical center position of the first curved portion <4a> and the second curved portion <4b> is the center of the annular recess <11>. The position is substantially the same as the position <C>. The uppermost part of the spring member <1>, which is the uppermost part of the first curved part <4a> and the second curved part <4b>, is located above the annular concave center position <C>.
 また、樹脂製弾性体<9>内のバネ部材<1>の最上部が環状凹部<11>の最上部位置から上方に位置している。大キャッチでは0.43mm、小キャッチでは0.37mmの位置である。よって、バネ部材<1>がある環状凹部<11>付近は、該硬質のバネ部材<1>により、変形し難い中央硬めの構造となっている。このようなバネ部材<1>が中心に位置している形態においても、キャッチ<B>を摘んだときの摘み力による内側への押圧力が、該バネ部材<1>に強く作用する。従って、前記したキャッチ<A>で述べたことと同様なピン挟持力増強動作となるものである。 Also, the uppermost part of the spring member <1> in the resin elastic body <9> is located above the uppermost position of the annular recess <11>. The position is 0.43 mm for the large catch and 0.37 mm for the small catch. Therefore, in the vicinity of the annular recess <11> where the spring member <1> is located, the hard spring member <1> has a hard central structure that is difficult to deform. Even in such a configuration in which the spring member <1> is located at the center, the inward pressing force by the picking force when the catch <B> is picked acts strongly on the spring member <1>. Therefore, the pin clamping force increasing operation is the same as that described in the above catch <A>.
 本発明は以上のような従来技術の欠点に鑑み、弾性構造体を指で摘みその摘み力を強めてのピンからの抜き操作において、ピン挟持箇所のピン挟持力が著しく増大して著しく抜き難くなることが生じないピアス用キャッチを提供することを目的としている。 In view of the drawbacks of the prior art as described above, the present invention makes it difficult to remove the pin from the pin when the elastic structure is picked with a finger and the pin is pulled from the pin with a strong picking force. It aims to provide a piercing catch that never happens.

 本発明の請求項1~6はそれぞれ次に述べるような効果を奏する。
 請求項1記載の発明は以下のような効果を奏する。
(1)ピン挟持硬質体の最上部位置が、弾性構造体胴部の最上部位置より1mm以上(従来技術の3倍以上)下方に位置してなる広い上下距離となっている。よって、弾性構造体上側凸部と弾性構造体胴部の1mm以上の部位が、ピン挟持硬質体の無い弾性構造体のみの上側軟らかめ構造部位を形成している。それより下側はピン挟持硬質体を有する下側硬め構造部位を形成している。
Claims 1 to 6 of the present invention have the following effects.
The invention described in claim 1 has the following effects.
(1) The uppermost position of the pin clamping hard body is a wide vertical distance located 1 mm or more (three times or more of the prior art) below the uppermost position of the elastic structure body. Therefore, the 1 mm or more site | part of an elastic structure upper side convex part and an elastic structure body part forms the upper soft structure structure part only of an elastic structure without a pin clamping hard body. The lower side forms a lower stiff structure portion having a pin clamping hard body.
 これにより、親指と人差指で弾性構造体上側凸部と弾性構造体胴部を摘み、その摘み力を強めると、上側軟らかめ構造部位は潰れ変形するともに、弾性構造体上側凸部には押し上げ作用が働き、下側硬め構造部位には押し下げ作用が働く。上側軟らかめ構造部位を形成している弾性構造体胴部(以下「軟らか構造形成胴部位」という。)は、指による押し潰し作用と前記押し上げ作用と前記押し下げ作用によって、上下方向に伸びる伸び形態(以下「胴部伸び形態」という。)となる。
 また、弾性構造体上側凸部の下部も上方に押され反り上がった反り逃げ形態となる。
As a result, when the elastic structure upper convex part and the elastic structure body part are picked with the thumb and forefinger and the picking force is increased, the upper soft structure part is crushed and deformed, and the elastic structure upper convex part is pushed up. Works, and a lowering action acts on the lower stiff structure portion. The elastic structure body part forming the upper soft structure part (hereinafter referred to as “soft structure forming body part”) is extended in the vertical direction by the crushing action by the finger, the pushing-up action, and the pushing-down action. (Hereinafter referred to as “trunk stretch form”).
In addition, the lower part of the upper protrusion of the elastic structure is also pushed upward to be warped and escaped.
 前記胴部伸び形態では、ピン挟持硬質体が位置している下側硬め構造部位は下方へ押し逃がす形態であるので、摘み指の摘み力がピン挟持硬質体に直接的には作用することが無いないし小さい挟持力非作用形態となる。よって、親指と人差指で弾性構造体を摘んでその摘み力を強めてピンから抜き操作を行う際に、ピン挟持体のピン挟持力を直接的には強めることのないピアス用キャッチを実現している。また、胴部伸び形態によって摘み指による摘み感が、確りとした安定感、安心感のあるもの、フィット感のある摘み持ちやすさが良好なピアス用キャッチを実現している。 In the trunk extension configuration, the lower stiff structure portion where the pin clamping hard body is located is configured to be pushed downward, so that the pinch finger picking force may directly act on the pin clamping hard body. There is no or small clamping force non-operational form. Therefore, when pinching the elastic structure with the thumb and forefinger and pulling it out from the pin by increasing the picking force, a piercing catch that does not directly increase the pin clamping force of the pin clamping body is realized. Yes. In addition, the gripping feeling with the picking finger is realized by the body stretch form, and the catch for piercing with a sense of stability, security, and easy to hold with a good fit is realized.
 キャッチの親指と人差指による摘み形態は指先による摘み形態以外に、指横腹部位摘み形態がある。これは、爪が長いないし長いネイルを付けているなどによって、指先では摘まめないので、爪同士が当たらない親指と人差指の横腹部位同士で摘む指横腹部位摘み形態である(図5の図(b)参照)。このような指横腹部位摘み形態でも、本発明はフィット感の良い摘み持ちと抜き易さを実現する。 ¡Picking with the thumb and forefinger of the catch includes the finger flank part picking form in addition to the fingertip picking form. This is a finger flank portion picking form in which the nails are not picked by the fingertips due to long or long nails attached, etc., and the finger flank portions are picked between the flank portions of the thumb and index finger where the nails do not touch each other (FIG. 5 ( b)). Even in such a finger flank region picking form, the present invention realizes a good gripping and easy removal.
 請求項2載の発明は、以下のような効果を奏する。
弾性構造体上側凸部の上下幅が0.6mm~2.0mmであり、かつ、該弾性構造体上側凸部が指に掛かる鈍角部位又は鋭角部位を有する形態であり、前記鈍角部位および前記鋭角部位が湾曲角形態では半径0.5mm以下の湾曲角である。
 よって、弾性構造体上側凸部の鈍角部位又は鋭角部位が、指の摘まみ力を強めるとより指に食い込み、滑り難い摩擦大の強い掛かり状態となる。この強い掛かり状態により上下幅0.6mm~2.0mmの弾性構造体上側凸部は上方(図において)に反り逃げる反り逃げ形態となり、その反り逃げ距離だけ指の摘み部位がピン挟持硬質体から離れる指逃げ形態とになる。この指逃げ形態によってピン挟持硬質体の直接的抑え込みが回避され、ピン挟持体のピン挟持力を直接的には強めることのないピアス用キャッチを実現する。また、摘み力の低減化、フィット感と摘み持ちやすさの向上を実現する。
The invention according to claim 2 has the following effects.
The upper and lower widths of the upper protrusion of the elastic structure are 0.6 mm to 2.0 mm, and the upper protrusion of the elastic structure has an obtuse angle part or an acute angle part that is applied to the finger, and the obtuse angle part and the acute angle When the portion has a curved angle form, the radius is 0.5 mm or less.
Therefore, when the obtuse angle part or the acute angle part of the convex part on the upper side of the elastic structure increases the picking force of the finger, the finger is further bitten, and it is in a state of strong friction that is hard to slip. Due to this strong engagement state, the upper convex portion of the elastic structure having a vertical width of 0.6 mm to 2.0 mm is warped upward (in the figure) and the finger picking part is separated from the pin clamping hard body by the warping escape distance. It becomes a finger escape form to leave. This finger escape form avoids the direct pinching of the pin clamping hard body, and realizes a piercing catch that does not directly increase the pin clamping force of the pin clamping body. In addition, the picking power is reduced, and the fit feeling and the ease of picking are improved.
 請求項3載の発明は、以下のような効果を奏する。
 弾性構造体胴部の上下幅が1.3mm以上であり、かつ、ピン挟持硬質体の最上部位置が該弾性構造体胴部の中心位置より下方に位置してなる形態である。よって、弾性構造体胴部とピン挟持硬質体の最上部位置との距離は0.65mm以上(1.3÷2)である。0.65mm以上は、特許文献1の発明の大キャッチの0.27mm、小キャッチの0.25mmの、2倍以上の距離である。すなわち、弾性構造体胴部のピン挟持硬質体の無い上側軟らかめ構造部位の上下距離が0.65mm以上と長いので、該上側軟らかめ構造部位が伸びやすい形態となっている。
 この上側軟らかめ構造部位が伸びやすい形態によって、指の摘まみ力を強めると該上側軟らかめ構造部位が伸び、その伸びた距離だけ指の摘み部位がピン挟持硬質体から離れる指逃げ形態とになる。この指逃げ形態によってピン挟持硬質体の直接的抑え込みが回避され、ピン挟持体のピン挟持力を直接的には強めることのないピアス用キャッチを実現する。また、摘み力の低減化、フィット感と摘み持ちやすさの向上を実現する。
The invention according to claim 3 has the following effects.
The upper and lower width of the elastic structure body is 1.3 mm or more, and the uppermost position of the pin-clamping hard body is located below the center position of the elastic structure body. Therefore, the distance between the elastic structure body and the uppermost position of the pin clamping hard body is 0.65 mm or more (1.3 / 2). The distance of 0.65 mm or more is twice or more the distance of 0.27 mm for the large catch of the invention of Patent Document 1 and 0.25 mm for the small catch. That is, since the vertical distance of the upper soft structure portion without the pin-clamping hard body of the elastic structure body is as long as 0.65 mm or more, the upper soft structure structure portion is easily stretched.
By increasing the gripping force of the finger by the form in which the upper softening structure part is easy to extend, the upper softening structure part is extended, and the finger picking part is separated from the pin clamping hard body by the extended distance. Become. This finger escape form avoids the direct pinching of the pin clamping hard body, and realizes a piercing catch that does not directly increase the pin clamping force of the pin clamping body. In addition, the picking power is reduced, and the fit feeling and the ease of picking are improved.
 請求項4載の発明は、請求項1又は3記載の発明と同様な効果を奏する。 The invention according to claim 4 has the same effect as the invention according to claim 1 or 3.
 請求項5記載の発明は、請求項1~3又は4記載の発明と同様な効果を奏するとともに、次に述べるような効果を奏する。
(1)弾性構造体下側凸部で指先が外側に逃がされ、該弾性構造体下側凸部の側部を強く摘むことが回避されるので、ピン挟持硬質体への影響が弱められる。また、弾性構造体下側凸部に当たっている指先の押力によって該弾性構造体下側凸部が下方に押し下げられ、横押しの作用を下方に逃がすので、ピン挟持硬質体への影響が弱められる。さらに、弾性構造体下側凸部の横肉厚によって指の摘み力が緩和され、ピン挟持硬質体への影響が緩和される。
(2)弾性構造体下側凸部にピン挟持硬質体の半分以上が位置した形態であるので、ピン挟持硬質体に付勢力を与える弾性体構造部位の側部厚みを弾性構造体下側凸部によって十分に確保することができる。これによって、ピン挟持硬質体周辺の強度を考慮することなく、弾性体構造体胴部の胴太さの一部ないし全部を、細い形態(くびれを含む)とすることを可能としている。例えばピン挟持硬質体の横幅よりも細い胴部とすることも可能とする。細い胴部とすることによって、弾性体構造体胴部をより伸びやすく、伸びの大きいものとすることが可能となる。
The invention described in claim 5 has the same effects as those of the invention described in claims 1 to 3 or 4 and also has the following effects.
(1) Since the fingertip is relieved to the outside by the elastic structure lower convex part and it is avoided to strongly pick the side part of the elastic structure lower convex part, the influence on the pin clamping hard body is weakened. . Further, the elastic structure lower convex portion is pushed down by the pressing force of the fingertip that hits the elastic structure lower convex portion, and the side pushing action is released downward, so the influence on the pin clamping hard body is weakened. . Furthermore, the pinch strength of the finger is mitigated by the lateral wall thickness of the lower convex portion of the elastic structure, and the influence on the pin clamping hard body is mitigated.
(2) Since more than half of the pin-clamping hard body is located on the lower convex part of the elastic structure, the thickness of the side part of the elastic structure part that applies an urging force to the pin-clamping hard body is set to the lower convex part of the elastic structure. It can be sufficiently secured by the part. Accordingly, a part or all of the body thickness of the elastic body body can be made into a thin form (including a constriction) without considering the strength around the pin clamping hard body. For example, it is possible to make the body thinner than the lateral width of the pin-clamping hard body. By using a thin body portion, it is possible to make the elastic body body body portion more easily stretchable and larger in elongation.
 請求項6記載の発明は、請求項1~4又は5記載の発明と同様な効果を奏するとともに、弾性構造体上側凸部の表面に形成された微細な凸凹からなる滑り止め部位は、摘んだ指の滑り難さと指掛かりを強化し、よって摘み易さと抜き操作易さを大きく向上したものとしている。また、上型、弾性構造体上側凸部と弾性構造体胴部が形成される非分割の中型、下型で形成する形態では、前記中型からの抜き易さを実現している。 The invention described in claim 6 has the same effect as that of the invention described in claims 1 to 4 or 5, and a non-slip portion made of fine unevenness formed on the surface of the upper protrusion of the elastic structure is picked. The finger slipping difficulty and finger hooking are strengthened, and thus the ease of picking and the ease of pulling out are greatly improved. Further, in the form formed by the non-divided middle mold and the lower mold in which the upper mold, the elastic structure upper convex part and the elastic structure body part are formed, it is easy to remove from the middle mold.

In the embodiment of the present invention shown in FIGS. 1 to 6, the piercing catch 1 has a picking force picked by a finger such as a silicon rubber member, a natural rubber member, a synthetic rubber member, or an elastic synthetic resin member. An elastic structure 2 made of an elastic material that is elastically deformed when strengthened, and that is inserted into and removed from a pin 3 that is a pier spin by picking with a finger;
A pin insertion hole 44 into which the pin 3 is inserted, provided upward from the bottom of the elastic structure 2;
Elasticity that forms the upper side of the elastic structure 2, bites into the finger that has picked up the elastic structure 2, and protrudes over the entire circumference of the side part with a substantially right angle (if it is obtuse) A structure upper projection 10;
An elastic structure body 8 having a smaller width than the elastic structure upper protrusion 10, which is formed below the elastic structure upper protrusion 10 of the elastic structure 2;
An elastic structure lower convex portion 9 having a lateral protrusion width larger than that of the elastic structure upper convex portion 10 in a form protruding over the entire circumference on a side portion formed at the lower portion of the elastic structure body portion 8; ,
The upper end surface of the lower protrusion 9 of the elastic structure, the connecting surface of the upper surface and the elastic structure body 8, or the fingertip of the finger picking up the elastic structure 2 composed of the upper surface and the connecting surface is used. Part 11 per finger to stop;
For pinning up the plate, the pin 3 inserted in the pin insertion hole 4 is inserted in the pin insertion hole 4 in a state of being sandwiched between the half or more in the elastic structure lower convex portion 9 and is integrally formed. A pin clamping rigid body 6 made of a rigid member having a first clamping part 6a and a second clamping part 6b in which a bead 15 is formed;
It has a configuration including a pin clamping portion 6c that is a portion for pinching the pin 3 of the first clamping portion 6a and the second clamping portion 6b.

As a result, the inserted pin 3 is inserted by pushing the first holding part 6a and the second holding part 6b laterally outward. When the pin 3 is inserted, the first sandwiching portion 6a and the second sandwiching portion 6b, which are hard members, are opened and moved in the laterally outward direction while deforming the elastic structure 2 without being deformed. The elastic structure 2 is in a state in which an elastic push-back force that tries to push back the first sandwiching portion 6a and the second sandwiching portion 6b with its elastic repulsion force is always applied, and the first sandwiching portion is caused by this elastic push-back force. The clamping force which clamps the pin 3 of 6a and the 2nd clamping part 6b is strengthened.

The same applies to a configuration in which there is an inclined connecting portion between the body portion and the lower convex portion of the elastic structure.)

 以上の寸法、形状等は例示であり、本発明は上記寸法に限定されるものではない。

The above dimensions, shapes, and the like are examples, and the present invention is not limited to the above dimensions.
The vertical width of the elastic structure is 3.5 mm to 10.0 mm, preferably 4.0 mm to 8.0 mm, more preferably 4.5 mm to 6.5 mm.
The lateral width of the elastic structure is 3.5 mm to 10.0 mm, preferably 4.0 mm to 8.0 mm, and more preferably 4.0 mm to 6.5 mm.
The lateral width of the upper protrusion of the elastic structure is 3.0 mm to 8.0 mm, preferably 3.5 mm to 7.0 mm, and more preferably 4.0 mm to 6.5 mm.
The vertical width of the elastic structure body portion is 1.3 mm or more, preferably 1.6 mm or more, more preferably 1.8 mm or more.
The body diameter of the elastic structure body is 2.0 mm to 6.5 mm, preferably 2.5 mm to 5.5 mm, and more preferably 3.0 mm to 5.0 mm.
 弾性構造体上側凸部10は上下幅0.975mmとしている。それは、2.0mm以上だと幅広(厚肉)のため上方への反り逃げが悪くなり、0.6mm以下だと凸部の潰れ変形が大きすぎて指への掛かり(食い込み)が悪くなるからである。適当な反り逃げが得られる弾性構造体上側凸部10の上下幅は、0.6mm~2.0mm、好ましくは、0.6mm~1.7mm、より好ましくは0.6mm~1.5mm、さらに好ましくは0.7mm~1.2mmとするのがよい。また、弾性構造体上側凸部10の下部側の指掛かり部位または指食い込み部位は、鈍角形態ないし鋭角形態とするのがよく、該鈍角形態および鋭角形態は湾曲角形態では半径0.5mm以下の湾曲角とするのが、良好な指への掛かり状態を得るものとできる。 The elastic structure upper convex portion 10 has a vertical width of 0.975 mm. If it is 2.0 mm or more, it is wide (thick) and the upward warping escapes worse, and if it is 0.6 mm or less, the crushing deformation of the convex part is too large and the hooking on the finger (bite) worsens. It is. The upper and lower widths of the upper protrusion 10 of the elastic structure that can provide appropriate warp relief are 0.6 mm to 2.0 mm, preferably 0.6 mm to 1.7 mm, more preferably 0.6 mm to 1.5 mm, The thickness is preferably 0.7 mm to 1.2 mm. Further, it is preferable that the finger catching portion or the finger biting portion on the lower side of the elastic structure upper convex portion 10 has an obtuse angle shape or an acute angle shape, and the obtuse angle shape and the acute angle shape have a radius of 0.5 mm or less in a curved angle shape. It is possible to obtain a good hooking state on the finger by setting the bending angle.
 また、弾性構造体上側凸部10の頂部形態は、緩やかな湾曲面としている。これによって、中のピン挟持硬質体6が大きく見える凸レンズの機能を果たしている。さらに、緩やかな湾曲面とすることで、弾性構造体上側凸部10の上下肉厚幅を、摘み時の掛かりと反り逃げが好適となる厚さにしている。 Moreover, the top form of the upper protrusion 10 of the elastic structure is a gently curved surface. This fulfills the function of a convex lens in which the pin pinching rigid body 6 inside can be seen larger. Furthermore, by making it a gentle curved surface, the upper and lower wall thickness width of the elastic structure upper convex portion 10 is set to a thickness that is suitable for hooking and warping escape.
 ピン挟持硬質体6の最上部位置が、弾性構造体胴部8の最上部位置より1.725mm下方(0.6mm以上)に位置してなる広い上下距離となっている(後述する「特徴形態(1)」)。従って、弾性構造体上側凸部10と弾性構造体胴部8の1.725mm部位(0.6mm以上)が、ピン挟持硬質体6の無い弾性構造体2のみの上側軟らかめ構造部位となっている。それより下側はピン挟持硬質体6を有する下側硬め構造部位となっている。
 これにより、親指と人差指で弾性構造体上側凸部10と弾性構造体胴部8を摘みその摘み力を強めると、上側軟らかめ構造部位は潰れ変形する。その変形および指のハの字摘み形態によって、弾性構造体上側凸部10には押し上げ作用が働き、下側硬め構造部位には押し下げ作用が働く。そして、上側軟らかめ構造部位を形成している弾性構造体胴部8(以下「軟らか構造形成胴部位」という。)は指による押し潰し作用と前記押し上げ作用と前記押し下げ作用によって、上下方向に伸びる伸び形態(以下「胴部伸び形態」ともいう。)となる。また、弾性構造体上側凸部10の下部も上方に押し反り上がった反り逃げ形態となり、指の弾性構造体胴部8への入りと潰しを行い易くする。
The uppermost position of the pin clamping hard body 6 is a wide vertical distance located 1.725 mm below (0.6 mm or more) from the uppermost position of the elastic structure body 8 (see “Features” described later). (1) "). Therefore, the 1.725 mm part (0.6 mm or more) of the elastic structure upper convex part 10 and the elastic structure body part 8 becomes the upper soft structure part of only the elastic structure 2 without the pin clamping hard body 6. Yes. The lower side is a lower stiff structure portion having a pin clamping hard body 6.
Thus, when the elastic structure upper projection 10 and the elastic structure body 8 are picked up with the thumb and forefinger to increase the picking force, the upper soft structure portion is crushed and deformed. Due to the deformation and the C-shaped shape of the fingers, the elastic structure upper convex portion 10 has a push-up action, and the lower hard structure portion has a push-down action. The elastic structure body part 8 (hereinafter referred to as “soft structure forming body part”) forming the upper soft structure part extends in the vertical direction by the crushing action by the finger, the pushing-up action, and the pushing-down action. It becomes an elongated form (hereinafter also referred to as “trunk stretched form”). In addition, the lower part of the upper protrusion 10 of the elastic structure also has a warp escape form in which the upper structure is pushed upward to make it easier for the finger to enter and collapse the elastic structure body 8.
 この胴部伸び形態は、ピン挟持硬質体6が位置している下側硬め構造部位は下方へ押し逃がす形態であるので、摘んだ指の摘み力がピン挟持体に直接的には作用することが無い、または小さい摘まみ力非作用形態となる。よって、親指と人差指で弾性構造体を摘んでその摘み力を強めてピンから抜き操作を行う際に、ピン挟持硬質体6のピン挟持力を直接的には強めることのないピアス用キャッチを実現している。
 また、胴部伸び形態および弾性構造体上側凸部の反り逃げ形態によって指の摘み感が、確りとした安定感、安心感のあるもの、フィット感のある摘み持ちやすさの良いピアス用キャッチを実現している。
In this body extension form, the lower stiff structure portion where the pin clamping hard body 6 is located is pushed downward and the picking force of the picked finger acts directly on the pin clamping body. There is no or small picking force non-acting form. Therefore, when catching an elastic structure with the thumb and forefinger to increase the picking force and pulling it out of the pin, a pinching catch that does not directly increase the pin clamping force of the pin clamping hard body 6 is realized. is doing.
In addition, the grip of the pierced ear with a sense of stability, a sense of security, and a fit that is easy to hold with a sense of grip is ensured by the body stretch form and the warp relief form of the upper protrusion of the elastic structure. Realized.
 摘み指の摘み部位は下方に広がるハの字摘み形態である(後述する「特徴形態(2)」)。それに加えて、前述の「特徴形態(1)」の構造から(参考として図5参照)、弾性構造体2を親指と人差指(中指の場合もあり)とで強めに摘んだ形態である摘み力強め形態(指横腹部位摘み形態(図5の(b)図参照)を含む。)は、上側軟らかめ構造部位が潰れ下側硬め構造部位が潰れない状態であるので、摘み指は下方に向かって広がったハの字摘み形態となる。 The picking part of the picking finger is a C-shaped picking form that spreads downward ("feature form (2)" described later). In addition, from the structure of the above-mentioned “characteristic form (1)” (see FIG. 5 for reference), the picking force is a form in which the elastic structure 2 is strongly picked with the thumb and index finger (may be the middle finger). In the strong form (including the finger flank part picking form (see FIG. 5B)), the upper soft structure part is crushed and the lower hard structure part is not crushed, so the pick finger is directed downward. It becomes the form of picking out the letter C.
 前記ハの字摘み形態は、上方に行くほど指間距離が狭くなる形態である。それは、上方に行くほど摘み力が強くなる摘み形態である。よって、ハの字摘み形態で摘み力を増すと、弾性構造体2の部位で強く抑える部位は、上側軟らかめ構造部位の弾性構造体上側凸部10と弾性構造体胴部8である。上側軟らかめ構造部位は、強く摘むと弾性構造体2の上方が潰れ反り伸び状態となりかつ胴部伸び状態となる上側潰れ伸び状態となる。この上側潰れ伸び状態は、摘み力を上方に逃がす摘み力上方逃がし状態である。このハの字摘み形態による摘み力上方逃がし状態によっても、弾性構造体下側凸部9が真横からは強く摘まれない状態となる。 The shape of picking up the C is such that the distance between the fingers becomes narrower as it goes upward. It is a picking form in which the picking power increases as it goes upward. Therefore, when the picking force is increased in the C-shaped picking form, the elastic structure upper convex part 10 and the elastic structure body part 8 of the upper soft structure part are strongly suppressed by the part of the elastic structure 2. When the upper soft structure portion is strongly picked, the upper part of the elastic structure 2 is in a state of being crushed and warped and stretched, and is in an upper state of being crushed and stretched. This upper side crushing extension state is a state in which the picking force is released upward to release the picking force upward. Even in the state where the picking force is released upward by the C-shaped picking form, the elastic structure lower convex portion 9 is not strongly picked from the side.
 前述した「特徴形態(1)」及び「特徴形態(2)」によって、第1の挟持部と第2の挟持部の挟持力が増強される横方向から、弾性構造体を指で摘んでその摘み力を強くしても、第1の挟持部と第2の挟持部が内側に寄ることが少なく、またはほとんど無い。よって、摘み抜き操作時にピン挟持箇所の挟持力が著しく強くなることがなく、弾性構造体上側凸部10が指に食い込み掛かっていることもあって、どの方向から摘んでもピアスピンから容易に抜くことができるピアス用キャッチを実現している。 From the lateral direction in which the clamping force between the first clamping part and the second clamping part is increased by the above-mentioned “characteristic form (1)” and “characteristic form (2)”, the elastic structure is picked with a finger. Even if the picking force is increased, the first holding portion and the second holding portion are rarely or hardly moved inward. Therefore, the pinching force at the pin clamping portion does not remarkably increase during the pinching operation, and the elastic structure upper convex portion 10 may bite into the finger, so that it can be easily pulled out of the pier spin from any direction. A piercing catch that can be used.
 ピン挟持硬質体6の最上部位置と弾性構造体胴部8の最上部位置の距離は、0.6mm以上がよい、好ましくは0.9mm以上がよい、より好ましくは、1.3mm以上がよい、さらに好ましくは1.5mm以上がよい。 The distance between the uppermost position of the pin clamping hard body 6 and the uppermost position of the elastic structure body 8 is preferably 0.6 mm or more, preferably 0.9 mm or more, more preferably 1.3 mm or more. More preferably, it is 1.5 mm or more.
 弾性構造体上側凸部10の下部角である角カットの無い鈍角部位または鋭角部位が指への食い込み掛かりを強くするので、弾性構造体上側凸部10の滑り難さを実現し、その反り逃げ形態もより大きくなる。よって、摘み力の低減化、フィット感と摘み持ちやすさの向上を実現する。上記鈍角ないし鋭角とは、半径0.3mm以内の湾曲角ないし直線カット3mm以内のカット角である。 Since the obtuse angle part or the acute angle part without the corner cut which is the lower corner of the elastic structure upper convex part 10 strengthens the biting into the finger, the elastic structure upper convex part 10 is difficult to slip, and its warpage escapes. The form is also larger. Therefore, a reduction in the picking power, an improvement in fit and ease of picking are realized. The obtuse angle or acute angle is a bending angle within a radius of 0.3 mm or a cutting angle within a straight cut of 3 mm.
 弾性構造体下側凸部9の機能について述べる。
(1)弾性構造体下側凸部9で指先が外側に逃がされ、該弾性構造体下側凸部9の側部を強く摘むことが回避されるので、ピン挟持硬質体6への影響が弱められる。また、弾性構造体下側凸部9に当たっている指先の押力によって該弾性構造体下側凸部9が下方に押し下げられ、横押しの作用を下方に逃がすので、ピン挟持硬質体6への影響が弱められる。弾性構造体下側凸部9の肉厚によって指摘み力が弱められ、ピン挟持硬質体6への影響が弱められる。
(2)弾性構造体下側凸部9にピン挟持硬質体6の半分以上が位置した形態であるので、ピン挟持硬質体6に付勢力を与える弾性体構造部位の側部厚みを弾性構造体下側凸部によって十分に確保することができる。
 これによって、弾性体構造体胴部8の胴太さの一部ないし全部を、細い形態(くびれを含む)とすることを可能としている。例えばピン挟持硬質体6の横幅よりも細い胴部とすることも可能とする。細い胴部とすることによって、弾性体構造体胴部8をより伸びやすい形態にできる。
The function of the elastic structure lower convex part 9 will be described.
(1) Since it is avoided that the fingertip is released to the outside by the elastic structure lower convex portion 9 and the side portion of the elastic structure lower convex portion 9 is strongly picked, the influence on the pin clamping hard body 6 Is weakened. Further, since the elastic structure lower convex portion 9 is pushed downward by the pressing force of the fingertip hitting the elastic structure lower convex portion 9 and the side pushing action is released downward, the influence on the pin clamping hard body 6 is affected. Is weakened. The pointing force is weakened by the thickness of the lower protrusion 9 of the elastic structure, and the influence on the pin clamping hard body 6 is weakened.
(2) Since more than half of the pin sandwiching hard body 6 is positioned on the lower convex portion 9 of the elastic structure, the side thickness of the elastic structure part that applies a biasing force to the pin sandwiching hard body 6 is determined as the elastic structure. It can be sufficiently secured by the lower convex portion.
Thereby, a part or all of the body thickness of the elastic body body body portion 8 can be made into a thin form (including a constriction). For example, it is possible to make the body narrower than the lateral width of the pin sandwiching rigid body 6. By setting it as a thin trunk | drum, the elastic body structure trunk | drum 8 can be made into the form which extends more easily.
 「ピン挿入孔4」は止り孔形態でもよい。
「弾性構造体下側凸部9に内設された、または弾性構造体下側凸部9から弾性構造体胴部8にまたがる形態で内設された、・・・ピン挟持硬質体6」には、全部位を埋設した全部位埋設形態(全部部位内設形態)とするのもよいし、一部を弾性構造体胴部8の底部から露出した一部露出形態(一部部位内設形態)とするなどの形態などがある。
The “pin insertion hole 4” may have a blind hole shape.
“Pin clamping rigid body 6, which is provided in the elastic structure lower convex portion 9, or is provided in a form extending from the elastic structure lower convex portion 9 to the elastic structure body portion 8”. May be all-embedded form in which all the parts are buried (all-parts-embedded form), or partly exposed form (part-part-built-in form in which a part is exposed from the bottom of the elastic structure body 8) ) And the like.
 指あたり部位11位置が、ピン挟持硬質体6と略同じかそれより上方に位置するようにするのもよい。また、弾性構造体下側凸部9の上部縁角に上方に突出する小凸部を設け、指当たりをより感じやすいものとするのもよい。 It is also possible that the position of the part 11 per finger is substantially the same as or higher than the pin-clamping hard body 6. Moreover, it is good also as providing the small convex part which protrudes upwards in the upper edge angle of the elastic structure lower side convex part 9, and making it easy to feel finger contact.
 上部縁角16は指あたり部位が広くなるよう、かつ、角を感じ易くなるようより鈍角とするのがよい。弾性構造体を指で軽く摘んだ指横腹部位摘み形態で、該指の指腹で該指あたり部位の当たりを確かに感じ取ることができる指あたり部位の形態は多様な形態がある。
 例えば、弾性構造体胴部より0.7mm以上横に突出している形態、図10に示すような指先が感じる凸凹や突起を設けた形態、弾性構造体下側凸部の上部縁に行くほど高くなるテーパー形態としたもの、弾性構造体胴部の太さと弾性構造体下側凸部の突出形態の関係、弾性構造体胴部の1.3mm以上の上下距離などが例示できる。
It is preferable that the upper edge angle 16 is a more obtuse angle so that the part around the finger becomes wider and the angle can be easily felt. There are various forms of the per finger area where the elastic structure can be lightly picked with a finger and the finger pad of the finger can surely feel the hit of the per finger area.
For example, a form projecting laterally by 0.7 mm or more from the elastic structure body part, a form provided with irregularities and protrusions felt by the fingertips as shown in FIG. 10, and higher as it goes to the upper edge of the lower convex part of the elastic structure Examples thereof include a taper configuration, a relationship between the thickness of the elastic structure body portion and the protruding shape of the lower protrusion of the elastic structure body, a vertical distance of 1.3 mm or more of the elastic structure body portion, and the like.
 本実施例1では、弾性構造体2は透明なシリコンゴム製部材からなっている。弾性構造体2に内設されたピン挟持硬質体6はゴールド、ホワイトゴールドまたはピンクゴールドなどの光沢性の金製部材からなっている。よって、ピン挟持硬質体6は透明な弾性構造体2によって、外からその色彩や形状が見える。
 上部部位21は緩やかな凸湾曲である凸レンズとして機能して、中のピン挟持硬質体6を大きく見せる。ピン挟持硬質体6の露出している底部面には14Kなどの刻印が施され、該露出形態によってルーペで即確実に確認できる。
 ピアス用キャッチ1は、金型60内にピン挟持硬質体6がセットされた状態で、加熱熔融したシリコンゴムが金型内に圧縮送り込まれ充填されて形成される(図6参照)。非透明の弾性構造体も本発明の技術的範疇に含まれるものである。
In the first embodiment, the elastic structure 2 is made of a transparent silicon rubber member. The pin clamping hard body 6 provided in the elastic structure 2 is made of a glossy gold member such as gold, white gold or pink gold. Therefore, the pin clamping hard body 6 can be seen from the outside by its transparent elastic structure 2.
The upper part 21 functions as a convex lens having a gentle convex curve, and shows the pin pinching hard body 6 inside. The exposed bottom surface of the pin-clamping hard body 6 is marked with 14K or the like, and can be surely confirmed with a loupe depending on the exposed form.
The piercing catch 1 is formed by filling and filling silicon rubber, which is heated and melted, with the pin clamping hard body 6 set in the mold 60 (see FIG. 6). Non-transparent elastic structures are also included in the technical scope of the present invention.
 ピン挟持硬質体は、ゴールドなどの貴金属に限定されず、チタン、ステンレス、メッキした鋼材、硬質性合成樹脂製部材など多種、多様な形態がある。また、その形態も挟持部が外側から内側に向かう湾曲形態に限られず、例えば図7に示すような内側から外側に向かう形態など多様な形態がある。 The pin sandwiched hard body is not limited to gold and other precious metals, but has a wide variety of forms such as titanium, stainless steel, plated steel, and hard synthetic resin members. Moreover, the form is not limited to the curved form in which the sandwiching portion is directed from the outside to the inside, and there are various forms such as a form from the inside to the outside as shown in FIG.
 下部連絡部14、弾性構造体下側凸部9の上部角および下部角は、5mmという小ささから視覚的には湾曲角とは見えない、鈍角に見える。すなわち、意匠的、実質的には下部連絡部14、弾性構造体下側凸部9の上部角線および下部線は一本の直線として見える。 The upper and lower corners of the lower connecting portion 14 and the lower convex portion 9 of the elastic structure appear as obtuse angles, which are visually invisible as a bending angle because of the small size of 5 mm. In other words, the upper corner lines and the lower lines of the design, substantially the lower connecting portion 14 and the elastic structure lower convex portion 9 appear as one straight line.
 摘み易さを優先させた場合、弾性構造体2の上下幅および横幅を0.5mm程度大きくした、上下幅5.5mm、横幅6.0mmの大きめの弾性構造体とするのがよい。この場合、弾性構造体上側凸部10、弾性構造体下側凸部9の上下幅、弾性構造体胴部8の胴太さは変えない。よって、弾性構造体胴部8の上下幅が2.475mmとなる。一見しただけで、弾性構造体2のものより大きめの弾性構造体が一回り大きく見える。
 全体が一回り大きくなりかつ弾性構造体胴部8の上下幅が2.475mmと長くなっていることから、掴み易さとフィット感がよりよいものとなる。
 横幅を変えない上下幅のみを大きくした形態でもよい。
When priority is given to the ease of picking, it is preferable that the elastic structure 2 has a large elastic structure 2 with a vertical width of 5.5 mm and a horizontal width of 6.0 mm, with the vertical width and horizontal width increased by about 0.5 mm. In this case, the vertical width of the elastic structure upper protrusion 10 and the elastic structure lower protrusion 9 and the body thickness of the elastic structure body 8 are not changed. Therefore, the vertical width of the elastic structure body portion 8 is 2.475 mm. At first glance, an elastic structure larger than that of the elastic structure 2 appears to be slightly larger.
Since the whole is enlarged one by one and the vertical width of the elastic structure body portion 8 is as long as 2.475 mm, the gripping and the fit feeling are better.
The form which enlarged only the up-and-down width which does not change a width may be sufficient.
 図6はピアス用キャッチ1の成型金型例を示している。
 金型60は弾性構造体2の最上部である上部部位21を形成する上型61と、弾性構造体上側凸部10の全部、弾性構造体胴部8の全部および弾性構造体下側凸部9の下部湾曲縁部位を除く大部分を形成する中型62と、弾性構造体下側凸部9の下部湾曲縁部位を形成する下型63とからなっている。
 中型62は非分割型であり、単に形成孔が設けられた形態である。また、中型62の弾性構造体下側凸部9および弾性構造体胴部8の上部箇所には、SG#116のホーニングによって梨地部位65が形成されている。この梨地部位65によって、弾性構造体下側凸部9および弾性構造体胴部8の上部箇所の表面には、図においてはハッチングで表現した微細な凸凹部位である滑り止め部位21が形成されている。
FIG. 6 shows an example of a molding die of the piercing catch 1.
The mold 60 includes an upper mold 61 that forms the upper part 21 that is the uppermost part of the elastic structure 2, all of the elastic structure upper protrusion 10, all of the elastic structure body 8, and lower elastic structure protrusion. 9 includes a middle die 62 that forms most of the lower curved edge portion except the lower curved edge portion 9 and a lower die 63 that forms the lower curved edge portion of the lower convex portion 9 of the elastic structure.
The middle mold 62 is a non-split type and is simply a form in which a formation hole is provided. In addition, a satin portion 65 is formed by SG # 116 honing at the upper portion of the elastic structure lower projection 9 and the elastic structure body 8 of the middle mold 62. Due to the satin portion 65, a non-slip portion 21 is formed on the surface of the upper portion of the lower protrusion 9 of the elastic structure and the upper portion of the elastic structure body 8, which is a minute convex recess expressed by hatching in the drawing. Yes.
 梨地部位65に磨き処理(鏡面処理)を行わなければ、滑り止め部位21は、透明部材である弾性構造体2にあっては、薄っすらとした曇り状態に見える。それは弾性構造体2内のピン挿入孔4や挿入されたピン3は明確に見える臼曇り形態である。
 滑り止め部位21は摘んだ指が滑り難く滑り止めとして機能し、弾性構造体2の摘み易さの安定性、弱い摘み力でのピンからの抜き取りやすさなど、ピン抜き操作性を大きく向上させる。
If the polishing process (mirror surface process) is not performed on the satin-finished area 65, the anti-slip area 21 looks thin and cloudy in the elastic structure 2 that is a transparent member. That is, the pin insertion hole 4 in the elastic structure 2 and the inserted pin 3 are in a mortar cloud form.
The anti-slip portion 21 functions as an anti-slip function, making it difficult for the picked finger to slip, and greatly improves the pin pulling operability such as the stability of the ease of picking of the elastic structure 2 and the ease of pulling out the pin with a weak picking force. .
 本実施例1においては、ホーニングによって梨地部位65を形成した後で、梨地部位65を凸凹が無くならない程度で鏡面磨き処理を行っている。こうすることで、滑り止め部位21の薄曇り状態が解消され、表面は光沢があって内部の透過が良好となり、肉眼では臼曇り状態が明確には認視できない程度となる。滑り止め部位21は光沢の凸凹部位となっているが、滑り止めとして機能する。中型62からの抜けやすさも機能する。 In the first embodiment, after the satin portion 65 is formed by honing, the specular portion 65 is mirror-polished to such an extent that unevenness is not lost. By doing so, the lightly clouded state of the non-slip portion 21 is eliminated, the surface is glossy and the internal transmission is good, and the frosted state cannot be clearly recognized with the naked eye. The non-slip portion 21 is in the form of a glossy concave, but functions as a non-slip. The ease of removal from the middle mold 62 also functions.
 中型62内にあるピアス用キャッチ1の取り出しは、上型61および下型63が固定されているプレス機から中型62を取り外し、取り出し用の治具にセットし、ピアス用キャッチ1の上部を1.2mmの押し出しピンによって押し、押し出すことで行う。
 押し出しピンが1.2mm以上の太さだと、弾性構造体2の外側への押し量が大きく、抵抗も増大し、抜いた後の弾性構造体2の変形が戻らない、当初の意匠形態が損なわれる。
 押し出しピンが1.2mm以下の太さだと、押し出しピンがピン挿入孔4に潜り込み押し出し抜きができない。これは、中型62の突出部位65である弾性構造体上側凸部10が掛かる部位が鏡面仕上げであるため、両者の密着が極めて高く摩擦ないし吸盤的作用が著しく大きいためと考えられる。
 梨地部位65を設けることで、中型62内にあるピアス用キャッチ1は、1.2mmの押し出しピンの押し出し操作で、変形も少なく、ピン挿入孔4へ押し出しピンの潜り込みも生じない、良好な押し出しが実現される。
The piercing catch 1 in the middle die 62 is taken out by removing the middle die 62 from the press machine to which the upper die 61 and the lower die 63 are fixed, setting it in a jig for taking out, and placing the upper portion of the piercing catch 1 on the 1 It is done by pushing and pushing with a 2mm push pin.
If the extrusion pin has a thickness of 1.2 mm or more, the pushing amount to the outside of the elastic structure 2 is large, the resistance increases, the deformation of the elastic structure 2 after being pulled out does not return, and the original design form is damaged. It is.
If the extrusion pin has a thickness of 1.2 mm or less, the extrusion pin enters the pin insertion hole 4 and cannot be extruded. This is presumably because the portion on which the upper protrusion 10 of the elastic structure, which is the protruding portion 65 of the middle mold 62, is mirror-finished, so that the close contact between them is extremely high and the frictional or sucker action is extremely large.
By providing the matte portion 65, the piercing catch 1 in the middle mold 62 is excellently extruded by pushing out the 1.2 mm push pin, and hardly deforms and does not cause the push pin to enter the pin insertion hole 4. Is realized.
 10×10=100の100個取りの金型とした場合、梨地部位65が無い金型では、100本の押し出しピンによる一斉の押し出しは、人が全体重をかけたとしても容易には抜けない。例えば身近にあった50t級のプレスの使用によって可能であった。これに対して、梨地部位65を設けた金型では、人が軽く体重をかけただけで、100個一斉に容易に抜き出すことができる。よて、高い生産性を実現する。 When 100 × 100 = 100 molds are used, with a mold without the satin portion 65, simultaneous extrusion by 100 extrusion pins does not come out easily even if the person puts the whole weight on it. . For example, it was possible by using a familiar 50t class press. On the other hand, in the mold provided with the satin portion 65, 100 people can be easily extracted all at once even if the person applies light weight. Therefore, high productivity is realized.
 図7に示す本発明の実施例2において、前記実施例1と主に異なる点は、ピン挟持硬質体をピン挟持硬質体19としたピアス用キャッチ17を形成した点にある。

In the second embodiment of the present invention shown in FIG. 7, the main difference from the first embodiment is that a piercing catch 17 having a pin clamping hard body 19 as a pin clamping hard body 19 is formed.
The pin clamping hard body 19 includes a base portion 18 having a pin through hole 13, a first clamping portion 19a in which the left side of the base portion 18 is bent upwards inwardly and the tip is bent outwardly in an inclined linear form, The right side of the portion 18 is bent upward on the inner side, and the tip of the second holding portion 19b is bent in the form of an inclined straight line, and the pin 3 of the first holding portion 19a and the second holding portion 19b is pinched. It consists of a pin clamping part 19c.
 下部連絡部を直角形態の隅角である下部連絡部20としている。この結果、弾性構造体胴部8の上下距離は2.225mmとなっている。

 ピン挟持硬質体19の最上部位置が弾性構造体胴部8の胴部中心位置Cより下方に位置する範囲で、ピン挟持箇所19cが指あたり部位11より上方に位置する形態でもよい。
The lower connecting portion is a lower connecting portion 20 that is a right angle corner. As a result, the vertical distance of the elastic structure body 8 is 2.225 mm.
The uppermost position of the pin clamping hard body 19 is located below the trunk center position C of the elastic structure trunk 8. The part 11 per finger | toe is located above the pin clamping location 19c.
The pin clamping part 19c may be positioned above the part 11 per finger in a range where the uppermost position of the pin clamping hard body 19 is located below the trunk center position C of the elastic structure body part 8.
 図8に示す本発明の実施例3において、前記実施例1と主に異なる点は弾性構造体を弾性構造体29とし、ピン挟持硬質体6の全部を弾性構造体29内に埋設してなる形態のピアス用キャッチ30を形成した点にある。
 弾性構造体29は、弾性構造体胴部31と、弾性構造体胴部31の上部に形成した該弾性構造体胴部31よりも幅広の弾性構造体上側凸部32と、弾性構造体胴部31の下部に形成した該弾性構造体胴部31よりも幅広で弾性構造体上側凸部32よりも幅狭の弾性構造体下側凸部33とからなっている。弾性構造体29の下部にはピン通し孔13に連絡するピン3を該ピン通し孔13に誘導する誘い込み部34が形成されている。
 形成する金型の中型は割り型である。
In the third embodiment of the present invention shown in FIG. 8, the main difference from the first embodiment is that the elastic structure is an elastic structure 29 and the entire pin clamping hard body 6 is embedded in the elastic structure 29. The point is that the piercing catch 30 is formed.
The elastic structure 29 includes an elastic structure body 31, an elastic structure upper protrusion 32 wider than the elastic structure body 31 formed on the elastic structure body 31, and an elastic structure body An elastic structure lower convex portion 33 that is wider than the elastic structure body portion 31 formed below the elastic member 31 and narrower than the elastic structure upper convex portion 32 is formed. In the lower part of the elastic structure 29, a guiding part 34 for guiding the pin 3 communicating with the pin through hole 13 to the pin through hole 13 is formed.
The middle mold to be formed is a split mold.
 弾性構造体下側凸部33の上部の指あたり部位35は、その縁角を略直角である鈍角としかつピン挟持箇所6cの上方に位置し、ピン挟持硬質体6の全部は弾性構造体29内とされている。また、弾性構造体上側凸部32の下部縁角27および上部縁角28は鈍角という、2か所の鈍角を有した形態となっている。また、弾性構造体上側凸部32の上下幅(肉厚)は0.8mm(0.6mm~2.0mmの範囲内)としている。 The finger contact portion 35 on the upper side of the lower protrusion 33 of the elastic structure has an obtuse angle that is a substantially right angle and is located above the pin clamping portion 6c, and the entire pin clamping hard body 6 is the elastic structure 29. It is said to be inside. In addition, the lower edge angle 27 and the upper edge angle 28 of the elastic structure upper convex portion 32 have two obtuse angles called obtuse angles. The vertical width (thickness) of the upper protrusion 32 of the elastic structure is 0.8 mm (within a range of 0.6 mm to 2.0 mm).
 図9に示す本発明の実施例4において、前記実施例1と主に異なる点は弾性構造体を弾性構造体38としてなるピアス用キャッチ37を形成した点にある。実施例4は、
 シリコンゴム製部材、天然ゴム製部材、合成ゴム製部材、弾性合成樹脂製部材などの弾性材料からなる弾性構造体38と、
 弾性構造体38に内設された、ピン挿入孔4に挿入状態にあるピン3を対抗挟持形態で挟持する第1の挟持部6aと第2の挟持部6bを有してなる硬質製部材からなるピン挟持硬質体6と、
 弾性構造体38の弾性構造体胴部41と、
 弾性構造体胴部41の上部側の側部に形成された、弾性構造体38を摘んだ指がかかる弾性構造体上側凸部10と、
 弾性構造体胴部41の下部側に形成された、該弾性構造体胴部41よりも小径の弾性構造体下側小径部40と、
 弾性構造体胴部41の下縁角からなる下指掛かり部42と、を備えている。また、
 第1の挟持部6aと第2の挟持部6bが弾性構造体下側小径部40内に位置し、ピン挟持箇所6cの位置が、弾性構造体下側小径部40と弾性構造体胴部41の境より下方に位置している。
 弾性構造体胴部41の上下幅は1.5mmとしているが、これは1.4mm以上が良いく、好ましくは1.7mm~以上が良い。より好ましくは1.9mm以上である。
In the fourth embodiment of the present invention shown in FIG. 9, the main difference from the first embodiment is that a piercing catch 37 having an elastic structure 38 as an elastic structure 38 is formed. Example 4
An elastic structure 38 made of an elastic material such as a silicon rubber member, a natural rubber member, a synthetic rubber member, or an elastic synthetic resin member;
From a rigid member having a first clamping part 6a and a second clamping part 6b, which is provided in the elastic structure 38 and clamps the pin 3 inserted in the pin insertion hole 4 in a facing clamping manner. A pin sandwiching rigid body 6 and
An elastic structure body 41 of the elastic structure 38;
An elastic structure upper convex portion 10 on which a finger holding the elastic structure 38 is formed on the upper side portion of the elastic structure body 41;
An elastic structure lower small-diameter portion 40 having a smaller diameter than the elastic structure body 41 formed on the lower side of the elastic structure body 41;
And a lower finger hook portion 42 formed of a lower edge angle of the elastic structure body portion 41. Also,
The first clamping portion 6a and the second clamping portion 6b are located in the elastic structure lower side small diameter portion 40, and the pin clamping portion 6c is positioned at the elastic structure lower side small diameter portion 40 and the elastic structure body portion 41. It is located below the border.
The upper and lower width of the elastic structure body 41 is 1.5 mm, which is preferably 1.4 mm or more, and preferably 1.7 mm or more. More preferably, it is 1.9 mm or more.
 弾性構造体38を摘んだ指は最下部の内側に凹位置している弾性構造体下側小径部40には届かない、または届いても摘み力が強く作用することが無い。そして、指横腹部位摘み形態を含め摘んだ指は弾性構造体上側凸部10と下指掛かり部42の二箇所が食い込み掛かる二箇所摘み掛かり形態となるので、強く摘まなくても掛かり摩擦が大きく容易に抜き操作が行える。
 また、強く摘まなくてよい形態によって、第1の挟持部6aと第2の挟持部6bへの摘み力の影響を小さいものとしている。そして、ピン挟持箇所6cが摘み作用の及ばないないし小さい弾性構造体下側小径部40内に位置しているので、ピン挟持箇所6cの真横からの抑え込み作用は無い、ないし極めて小さいものとなる。よって、摘み抜き操作時にピン挟持箇所の挟持力が著しく強くなることが生じない。
The finger that picks up the elastic structure 38 does not reach the elastic structure lower small-diameter portion 40 that is recessed in the lowermost part, or the picking force does not act strongly even if it reaches. And since the finger picked including the finger lateral abdominal part picking form becomes a two-point picking form in which the two points of the elastic structure upper convex part 10 and the lower finger catching part 42 bite into, the hooking friction is large even if it is not picked strongly. Can be easily removed.
Moreover, the influence of the picking force on the first holding part 6a and the second holding part 6b is made small by the form that does not have to be strongly picked. And since the pin clamping location 6c does not reach the picking action or is located in the small elastic structure lower side small diameter portion 40, the pin clamping location 6c is not restrained from the side, or is extremely small. Therefore, the pinching force of the pin clamping portion does not increase significantly during the picking operation.
 図10に示す本発明の実施例5において、前記実施例1と主に異なる点は弾性構造体を弾性構造体44とし、ピン挟持硬質体6の全部を弾性構造体44内に埋設形態としてなるピアス用キャッチ45を形成した点にある。
 弾性構造体44は、弾性構造体上側凸部を、側部を一つの尖がり形態とした弾性構造体上側凸部46とし、弾性構造体胴部をくびれ形態の弾性構造体胴部47としている。摘み動作によって最も伸びるのは弾性構造体胴部47のくびれ部47aとなる。弾性構造体胴部47のくびれ部47aの下部傾斜面が指あたり部位48となる。弾性構造体下側凸部9の縁角は小さく上方に突出した指当たり突起49が形成されていて、指が当たったことを該指が確かに感じるようにしている。くびれ部47aの胴径は3.0mmとしているが、2.0mm~3.5mmであればよい。
In the fifth embodiment of the present invention shown in FIG. 10, the main difference from the first embodiment is that the elastic structure is an elastic structure 44 and the pin clamping hard body 6 is entirely embedded in the elastic structure 44. The pierce catch 45 is formed.
In the elastic structure 44, the upper protrusion of the elastic structure is an upper protrusion 46 of an elastic structure having a single pointed side, and the elastic structure body 47 is a constricted elastic structure body 47. . It is the constricted portion 47a of the elastic structure body portion 47 that extends most by the picking operation. The lower inclined surface of the constricted portion 47 a of the elastic structure body portion 47 becomes a finger contact portion 48. The elastic structure lower convex portion 9 has a small edge angle and is formed with a finger contact projection 49 protruding upward, so that the finger can surely feel that the finger has hit. The waist diameter of the constricted portion 47a is 3.0 mm, but may be 2.0 mm to 3.5 mm.
 弾性構造体44の上部には上部凹部43が設けられている。摘み力を強くした際に弾性構造体上側凸部46の上部側が潰れ変形しやすくしている。また、弾性構造体上側凸部46の側部突起部位である鋭角部位は、半径0.3mm(半径0.5mm以下)の湾曲角形態となっている。型は上型と下型のみでよい。 An upper recess 43 is provided on the upper portion of the elastic structure 44. When the picking force is increased, the upper side of the upper protrusion 46 of the elastic structure is easily crushed and deformed. Moreover, the acute angle part which is a side protrusion part of the elastic structure upper side convex part 46 has a curved angle form with a radius of 0.3 mm (a radius of 0.5 mm or less). Only the upper and lower molds may be used.
 図11に示す本発明の実施例6において、前記実施例1と主に異なる点は、弾性構造体を弾性構造体下側凸部の無い弾性構造体50とし、弾性構造体胴部を弾性構造体胴部52としてなるピアス用キャッチ51を形成した点にある。 In the sixth embodiment of the present invention shown in FIG. 11, the main difference from the first embodiment is that the elastic structure is an elastic structure 50 having no elastic structure lower convex portion, and the elastic structure body is an elastic structure. The point is that a piercing catch 51 as the body trunk portion 52 is formed.
 弾性構造体50は上下距離が3.5mm~8.5mmである。好ましくは4.0mm~7.5mm、さらに好ましくは4.5mm~6が良い。
 下方に行くにしたがって広がり形態の弾性構造体胴部52は、上下距離が4.0mmである。弾性構造体胴部52の上下距離は3.0mm~6mmが良い。弾性構造体胴部52の下方への広がりは、図よりも広くするのも良い。例えば、5.0mm~6.0mm。
 ピン挟持箇所6cの位置が、弾性構造体胴部52の底部面から3.0mm以内に位置している。好ましくは2.5mm以内、より好ましくは2.0mm以内が良い。
The elastic structure 50 has a vertical distance of 3.5 mm to 8.5 mm. The thickness is preferably 4.0 mm to 7.5 mm, more preferably 4.5 mm to 6.
The elastic structure body 52 that expands in the downward direction has a vertical distance of 4.0 mm. The vertical distance of the elastic structure body 52 is preferably 3.0 mm to 6 mm. The downward expansion of the elastic structure body portion 52 may be made wider than the figure. For example, 5.0 mm to 6.0 mm.
The position of the pin clamping portion 6 c is located within 3.0 mm from the bottom surface of the elastic structure body portion 52. Preferably it is within 2.5 mm, more preferably within 2.0 mm.
 本実施例では、弾性構造体胴部52の上下距離を4mmとし、ピン挟持箇所6cの位置が前記弾性構造体胴部52の底部面から2mmに位置させている。
 ピン挟持硬質体6を内設している弾性構造体50の下部側は、該ピン挟持硬質体6によって変形がし難い硬めの構造である下側硬め構造部位となっており、それより上部側である弾性構造体胴部52および弾性構造体上側凸部10は伸縮性の弾性材料のみの上側軟らかめ構造部位となっている。
In the present embodiment, the vertical distance of the elastic structure body 52 is 4 mm, and the pin clamping portion 6 c is positioned 2 mm from the bottom surface of the elastic structure body 52.
The lower side of the elastic structure 50 in which the pin clamping hard body 6 is provided is a lower stiffening structure portion that is a hard structure that is hard to be deformed by the pin clamping hard body 6, and the upper side thereof The elastic structure body 52 and the elastic structure upper convex part 10 are upper soft structure parts made of only a stretchable elastic material.
 ピン挟持硬質体6を内設している弾性構造体50の下部側は、該ピン挟持硬質体6によってその上部側よりは変形し難い硬めの構造である下側硬め構造部位となっている。
 弾性構造体50を親指と他の指とでの強め摘み形態は、下方に向かって広がり湾曲形態の両指がハの字形態で弾性構造体を摘んだハの字摘み形態となる。前記ハの字摘み形態は、上方に行くほど指間距離が狭くなる形態である。それは、上方に行くほど摘み力が強くなる摘み形態である。
 よって、ハの字摘み形態で摘み力を増すと、弾性構造体50の部位で強く抑える部位は最も上方にある弾性構造体上側凸部10である。
The lower side of the elastic structure 50 in which the pin holding hard body 6 is provided is a lower hard structure portion that is a hard structure that is harder to deform than the upper side by the pin holding hard body 6.
The strong picking form of the elastic structure 50 with the thumb and other fingers is a C-shaped picking form in which both fingers in a curved form spread downward and the elastic structure is picked up with a C-shaped form. The C-shaped picking form is a form in which the distance between fingers becomes narrower as it goes upward. It is a picking form in which the picking power increases as it goes upward.
Therefore, when the picking force is increased in the C-shaped picking form, the portion that is strongly restrained by the portion of the elastic structure 50 is the uppermost elastic structure protrusion 10.
 これにより、弾性構造体上側凸部10が最も強く摘み抑えられ、該弾性構造体上側凸部10が指に掛かった状態で、指の方は弾性構造体胴部52をそれほど強く摘むことなく、ピンからの抜き操作を行うことになる。
 よって、ピン挟持箇所6cの位置が、弾性構造体胴部52の中央部位より下方に位置させているピン挟持硬質体6への、ピン挟持箇所6cの真横からの抑え込み作用は生じ難いので、第1の挟持部6aと第2の挟持部6bを内側に強く押す作用は生じない、または生じたとしても微圧である。
 従って、どの方向から摘んでもピアスピンから容易に抜くことができるピアス用キャッチを実現している。
Thereby, the elastic structure upper convex portion 10 is most strongly held and suppressed, and the elastic structure upper convex portion 10 is hooked on the finger, and the finger does not grip the elastic structure body portion 52 so strongly. The operation to remove from the pin will be performed.
Therefore, it is difficult for the pin clamping part 6c to be restrained from the side of the pin clamping part 6c to the pin clamping hard body 6 positioned below the central part of the elastic structure body part 52. The action of strongly pressing the first clamping part 6a and the second clamping part 6b inward does not occur, or even if it occurs, it is a slight pressure.
Therefore, a piercing catch that can be easily removed from the pier spin from any direction is realized.
 図12は本発明の実施例7であって、前記実施例1と主に異なる点は、弾性構造体を弾性構造体55としてなるピアス用キャッチ56を形成した点にある。
 弾性構造体55は、弾性構造体胴部8にくびれ部57を形成している。くびれ部57は、高さ1.25mm、胴幅2.40mmとしている。弾性材料の少ない細いくびれ部57により、弾性構造体55を強く摘んだとき、くびれ部57が容易に伸長するので、指あたり部位11への指の押当たりを弱くできる。
 特に弾性構造体を硬めの材質にして、細いくびれ部57を上下距離1.0mm~2.5mmで胴太さが1.7~3mmとすることにより、可視的にみても明らかに伸びる形態を実現する。
FIG. 12 shows a seventh embodiment of the present invention, which is mainly different from the first embodiment in that a piercing catch 56 having an elastic structure as an elastic structure 55 is formed.
The elastic structure 55 forms a constricted portion 57 in the elastic structure body portion 8. The constricted portion 57 has a height of 1.25 mm and a trunk width of 2.40 mm. When the elastic structure 55 is strongly picked by the thin constricted portion 57 with a small amount of elastic material, the constricted portion 57 is easily extended, so that the finger pressing against the finger contact portion 11 can be weakened.
In particular, the elastic structure is made of a harder material, and the thin constricted portion 57 has a vertical distance of 1.0 mm to 2.5 mm and a body thickness of 1.7 to 3 mm, so that it can be clearly extended even when viewed visually. Realize.
 また、くびれ部57が細いことから指あたり部位11への指の当たり部位が第1の挟持部6aと第2の挟持部6bの真上に近い部位になる。よって、摘みの際の指による第1の挟持部6aと第2の挟持部6bの押し抑え方向は、真上に近い上方からの作用ということになる。
 これにより、第1の挟持部6aと第2の挟持部6bのピン挟持力を強める横からの押し抑え作用は生じないなし生じても弱いものとなる。
Further, since the constricted part 57 is thin, the contact part of the finger to the part 11 per finger becomes a part close to directly above the first holding part 6a and the second holding part 6b. Therefore, the pressing-down direction of the first clamping part 6a and the second clamping part 6b by the finger at the time of picking is an action from above close to the top.
As a result, the side-pressing action that increases the pin clamping force of the first clamping part 6a and the second clamping part 6b does not occur and is weak even if it occurs.
 第1の挟持部と第2の挟持部の頂上部を外側に位置させる、くびれ部をより胴細形態とすれば、摘み動作によって第1の挟持部と第2の挟持部を開き動作させて、または、第1の挟持部と第2の挟持部に開き作用を与えて、ピン挟持力を弱めてピンからの抜き取りを容易に行える形態も可能である。 If the top part of the first sandwiching part and the second sandwiching part are located outside, and the constricted part is made into a more narrow shape, the first sandwiching part and the second sandwiching part are opened by the picking operation. Alternatively, it is also possible to form the first holding portion and the second holding portion with an opening action so that the pin holding force is weakened so that the pin can be easily removed from the pin.

 前記弾性構造体胴部の上下幅が1.5mm以上であることを特徴とするピアス用キャッチ。
 弾性構造体を摘んだ指は最下部の内側に凹位置している弾性構造体下側小径部には届かない、または届いても摘み力が強く作用することが無い。
 そして、摘んだ指は弾性構造体上側凸部と下指掛かり部の二箇所が食い込み掛かる摘み掛かり形態となるので、強く摘まなくても掛かり摩擦が大きいので容易に抜き操作が行える。
 また、強く摘まなくてよい形態によって、第1の挟持部と第2の挟持部への摘み力の影響を小さいものとしている。
 そして、ピン挟持箇所が弾性構造体下側小径部と弾性構造体胴部の境より下方に位置しているので、ピン挟持箇所の真横からの抑え込み作用は無い、ないし極めて小さいものとなるので、摘み抜き操作時にピン挟持箇所の挟持力が著しく強くなることが生じない。

The finger that has picked up the elastic structure does not reach the lower small diameter portion of the elastic structure that is recessed inside the lowermost part, or even if it reaches, the picking force does not act strongly.
And since the picked finger has a pinching form in which two portions of the elastic structure upper convex portion and the lower finger hooking portion bite into, the picking finger can be easily pulled out because the hooking friction is large even if it is not strongly picked.
Moreover, the influence of the picking force on the first holding part and the second holding part is made small by the form that does not need to be strongly picked.
And since the pin clamping part is located below the boundary between the elastic structure lower small diameter part and the elastic structure body part, there is no restraining action from the side of the pin clamping part, or it becomes extremely small.
