Description

この考案は、装飾体に設けたピンを挟持するためのピアス用キャッチに関する。   This invention relates to a piercing catch for pinching a pin provided on a decorative body.

図6、図7を用いて、従来例のピアス用キャッチについて説明する。
図6に示すように、ピアスは、ピン1を設けてなる装飾体2と、後述するピアス用キャッチC1とからなる。
このピアスを使用するときは、具体的に示しないが、装飾体2に設けたピン1を、耳にあけたピアス孔に挿入し貫通させる。そして、耳の裏側で、このピン1をピアス用キャッチC1で受ける。
A conventional piercing catch will be described with reference to FIGS. 6 and 7.
As shown in FIG. 6, the piercing includes a decorative body 2 provided with a pin 1 and a piercing catch C <b> 1 described later.
When this piercing is used, although not specifically shown, the pin 1 provided on the decorative body 2 is inserted into the piercing hole opened in the ear and penetrated. Then, on the back side of the ear, the pin 1 is received by the piercing catch C1.

ピアス用キャッチC1は、金やプラチナ等の貴金属からなり、図7にも示すように、略円形の受け板部3と、この受け板部3の側部に一体に成形した一対の板バネ部4とからなる。
そして、一対の板バネ部4を受け板部3の裏側に向けて起立させるとともに、それぞれ内側に向けてカールさせるように曲げ加工している。このようにカールさせた一対の板バネ部4は、互いに隣り合う方向に弾性力を発揮することになる。
さらに、上記受け板部3の中央付近には、ピン挿入孔5を形成している。このようにしたピン挿入孔5の軸線は、上記カールさせた一対の板バネ部4間にちょうど位置することになる。
The piercing catch C1 is made of a noble metal such as gold or platinum, and as shown in FIG. 7, a substantially circular receiving plate portion 3 and a pair of leaf spring portions integrally formed on the side portion of the receiving plate portion 3 It consists of four.
The pair of leaf springs 4 are bent so as to stand toward the back side of the receiving plate 3 and curl toward the inside. The pair of leaf springs 4 curled in this way exerts an elastic force in directions adjacent to each other.
Further, a pin insertion hole 5 is formed near the center of the receiving plate portion 3. The axis of the pin insertion hole 5 made in this way is located exactly between the pair of curled leaf spring portions 4.

前述したように、ピン1を耳にあけたピアス孔に挿入したら、上記ピアス用キャッチC1を耳の裏側に持ってきて、ピン1を、このピアス用キャッチC1の受け板部3の表側からピン挿入孔5に挿入する。
そして、そのままピン1を進めていくと、このピン1が、隣り合う一対の板バネ部4間に挿入される。したがって、これら板バネ部4,4が弾性に抗して押し広げられ、ピン1を挟持する方向に弾性力を発揮することになる。
As described above, when the pin 1 is inserted into the pierced hole opened in the ear, the piercing catch C1 is brought to the back side of the ear, and the pin 1 is pinned from the front side of the receiving plate portion 3 of the piercing catch C1. Insert into the insertion hole 5.
When the pin 1 is advanced as it is, the pin 1 is inserted between a pair of adjacent leaf springs 4. Accordingly, the leaf springs 4 and 4 are spread against the elasticity, and exert an elastic force in the direction of pinching the pin 1.

上記従来例のピアス用キャッチC1では、金やプラチナ等の貴金属を曲げ加工して、弾性力を発揮させるようにしている。
しかし、金やプラチナ等の貴金属のいた部材を曲げ加工するだけでは、十分な挟持力を得ることができない。特に、金やプラチナ等の貴金属は一般的に軟らかい。このような貴金属製の板部材は、剛性に乏しく、特に、厚みの薄い板部材の場合には、どうしても弾性力に限界がある。
薄い貴金属製の板部材で形成した板バネ部4,4は、弾性力が弱く、ピアスのピン1に対する挟持力も弱区なってしまうため、その弾性力をできるだけ強くしようとすると、板バネ部4に厚みを持たせなければならず、材料コストが高くなってしまうという問題があった。
In the piercing catch C1 of the conventional example, a precious metal such as gold or platinum is bent to exert an elastic force.
However, sufficient bending force cannot be obtained only by bending a member having a precious metal such as gold or platinum. In particular, noble metals such as gold and platinum are generally soft. Such a plate member made of noble metal is poor in rigidity, and particularly in the case of a plate member having a small thickness, the elastic force is inevitably limited.
The leaf springs 4 and 4 formed of a thin precious metal plate member have a weak elastic force, and the pinching force of the piercing pin 1 is also weak. Therefore, when trying to make the elastic force as strong as possible, the leaf spring portion 4 However, there is a problem that the material cost becomes high.

また、弾性力を十分に発揮させられないということは、挟持したピン1がはずれてしまうことがあるということで、ピアスの装飾体2を紛失してしまう危険もある。
さらに、弾性力が弱いということは、言い換えれば、復帰力も弱く、一対の板バネ部4,4の間に、何回もピン1を出し入れするうちに、板バネ部4が変形してしまうおそれがある。そして、板バネ部4が変形して押し広げられたままになると、ピン1が抜けやすくなってしまう。
Moreover, the fact that the elastic force cannot be sufficiently exhibited means that the pin 1 that has been sandwiched may come off, and there is a risk of losing the pierced decorative body 2.
Furthermore, the weak elastic force means that the restoring force is also weak, and the leaf spring portion 4 may be deformed while the pin 1 is inserted and removed many times between the pair of leaf spring portions 4 and 4. There is. And if the leaf | plate spring part 4 deform | transforms and it is pushed and extended, it will become easy to remove | pin_out.

一方、最近では、樹脂製の本体にピン挿入孔を形成してなるピアス用キャッチが使用されることもある。このピアス用キャッチは、ピンをピン挿入孔に挿入すると、樹脂製本体自身の弾性力によって、そのピンを挟持するようにしたものである。
このようにした樹脂製のピアス用キャッチでは、通常は、十分な弾性力を発揮させることができ、耐久性にも優れるが、どうしても装飾性に欠け、安っぽいイメージをつくってしまう。
また、樹脂製の場合、ピンに人の脂や汗が付着すると、貴金属製のものに比べて滑りやすくなり、ピンが抜けてしまうこともあった。
この発明の目的は、貴金属製であっても、材料コストを抑えながら、十分な弾性力を発揮させて、ピンが抜け落ちを防ぐことができるピアス用キャッチを提供することである。
On the other hand, recently, a piercing catch having a pin insertion hole formed in a resin main body is sometimes used. In this piercing catch, when the pin is inserted into the pin insertion hole, the pin is held by the elastic force of the resin main body itself.
The resin piercing catch made in this way can usually exert a sufficient elastic force and is excellent in durability, but it is inevitably lacking in decoration and makes a cheap image.
Further, in the case of resin, when human fat or sweat adheres to the pin, it becomes slippery compared to a noble metal and the pin may come off.
An object of the present invention is to provide a piercing catch that can exhibit a sufficient elastic force and prevent a pin from falling off even if it is made of a noble metal, while suppressing the material cost.

この考案にピアス用キャッチは、ピン挿入孔を形成した受け板部と、この受け板部と一体に成形するとともに、受け板部の裏側に向かって起立させ、曲げ加工によりカールさせた一対の板バネ部とを備え、装飾体に設けたピンを、上記受け板部の表側からピン挿入孔に挿入すると、このピンが、カールさせた一対の板バネ部の間に位置して、その弾性力によって挟持される構成するとともに、上記一方の板バネ部から受け板部を通って他方の板バネ部に連続し、ほぼ平行に配置された複数の線状凹部によって波板部を形成した点に特徴を有する。   The catch for piercing in this device is a pair of plates that are formed integrally with the receiving plate portion with pin insertion holes, and are raised toward the back side of the receiving plate portion and curled by bending. When the pin provided on the decorative body is inserted into the pin insertion hole from the front side of the receiving plate portion, the pin is located between the pair of curled plate spring portions and its elastic force is provided. And the corrugated plate portion is formed by a plurality of linear concave portions arranged substantially in parallel to the other plate spring portion through the receiving plate portion from the one leaf spring portion. Has features.

この考案のピアス用キャッチによれば、波板部を設けることで、貴金属製の板状部材の厚みをそれほど厚くしなくても、板バネ部の弾性力を十分に高めることができる。従って、貴金属の使用量を抑え、すなわち材料コストを抑えながら、装飾体のピンが抜け落ちることがないピアス用キャッチを実現できる。   According to the piercing catch of the present invention, by providing the corrugated plate portion, the elastic force of the leaf spring portion can be sufficiently increased without increasing the thickness of the noble metal plate-like member so much. Therefore, it is possible to realize a piercing catch that prevents the pins of the decorative body from falling off while suppressing the amount of noble metal used, that is, reducing the material cost.

図1〜図5に、この考案の実施形態を示す。
図1、図2に示すピアス用キャッチC2は、略円形の受け板部3と、この受け板部の側部に一体に成形した一対の板バネ部4とからなる。なお、図2は、ピアス用キャッチC2の底面図である。
このピアス用キャッチC2は金やプラチナなどの貴金属製であるが、図3に示す板状部材から、一対の板バネ部4を受け板部3の裏側に向けて起立させるとともに、それぞれ内側に向けてカールさせるように曲げ加工して形成している。また、受け板部3のほぼ中央には、ピン挿入孔5を形成している。
1 to 5 show an embodiment of the present invention.
The piercing catch C2 shown in FIGS. 1 and 2 includes a substantially circular receiving plate portion 3 and a pair of leaf spring portions 4 formed integrally with the side portion of the receiving plate portion. FIG. 2 is a bottom view of the piercing catch C2.
The piercing catch C2 is made of a noble metal such as gold or platinum. From the plate-like member shown in FIG. 3, the pair of leaf spring portions 4 are raised to the back side of the receiving plate portion 3 and directed inward. And bent to form a curl. In addition, a pin insertion hole 5 is formed substantially at the center of the receiving plate portion 3.

上記ピアス用キャッチC2の概観は、図7に示す従来例のピアス用キャッチC1に似ているが、図1に示すピアス用キャッチC2は、一対の板バネ部4と受け板部3に連続する波板部6を備え、図3に示すように、上記板バネ部4,4は、ほとんどの部分が波板部6で構成されている。
この波板部6は、図3および図4に示すように、一方の板バネ部4から受け板部3を通過して他方の板バネ部4まで連続する複数の線状凹部7を設けることによって形成されている。これらの線状凹部7は、一定の厚みを備えた板状部材を曲げることによって形成したもので、これらの線状凹部7に隣接する部分は、線状凸部8になっている。
このように、線状凹部7と線状凸部8とが交互に配置されることによって、上記波板部6が形成されている。
The appearance of the piercing catch C2 is similar to the piercing catch C1 of the conventional example shown in FIG. 7, but the piercing catch C2 shown in FIG. 1 is continuous to the pair of leaf spring portions 4 and the receiving plate portion 3. As shown in FIG. 3, the leaf spring portions 4, 4 are configured by the corrugated plate portion 6 for the most part.
As shown in FIGS. 3 and 4, the corrugated plate portion 6 is provided with a plurality of linear concave portions 7 that continue from the one plate spring portion 4 through the receiving plate portion 3 to the other plate spring portion 4. Is formed by. These linear recesses 7 are formed by bending a plate-like member having a certain thickness, and portions adjacent to these linear recesses 7 are linear protrusions 8.
In this way, the corrugated plate portion 6 is formed by alternately arranging the linear concave portions 7 and the linear convex portions 8.

上記のような波板部6は、その線状凹部7の長さを曲げる方向、すなわち、図5に示す矢印x方向の曲げ力に対しては、波板部6を設けない場合と比べて剛性が高くなる。つまり、この浪板部6をカールさせて形成された板バネ部4,4の弾性力は強くなる。
従って、この考案の板バネ部4,4による挟持力は強く、装飾体2のピン1を確実に保持することができる。
The corrugated plate portion 6 as described above is compared with the case in which the corrugated plate portion 6 is not provided in the bending direction of the linear concave portion 7, that is, the bending force in the arrow x direction shown in FIG. Increases rigidity. That is, the elastic force of the leaf springs 4 and 4 formed by curling the slat plate 6 is increased.
Therefore, the clamping force by the leaf spring portions 4 and 4 of the present invention is strong, and the pin 1 of the decorative body 2 can be reliably held.

しかも、上記板バネ部4,4は、弾性力が強いため、ピン1の抜き差しを繰り返しても、変形が残ってしまうことがない。板バネ部4が変形したままになることがないので、一対の板バネ部4,4による挟持力を長期間維持することができる。
なお、この発明のピアス用キャッチC2は、貴金属を使用するので、樹脂製のピアス用キャッチと比べて、装飾性に優れている。
Moreover, since the plate spring portions 4 and 4 have strong elastic force, the deformation does not remain even if the pin 1 is repeatedly inserted and removed. Since the leaf spring portion 4 does not remain deformed, the clamping force by the pair of leaf spring portions 4 and 4 can be maintained for a long time.
In addition, since the catch C2 for piercing of this invention uses a noble metal, it is excellent in the decorativeness compared with the catch for piercing made of resin.
