Description

この発明は、装飾体に設けたピンを保持するためのピアス用キャッチに関する。 The present invention relates to a piercing catch for holding a pin provided on a decorative body.

図４〜図８を用いて、従来のピアス用キャッチについて説明する。
図４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Ｃとからなる。
このピアスを使用するときは、具体的に示していないが、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Ｃで受ける。
図５に示すピアス用キャッチＣは、金やプラチナ等の貴金属からなり、図６に示す板状部材ｃ１を成型したものであり、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。なお、図５，図６において互いに対応する部分には同じ符号をつけている。 A conventional piercing catch will be described with reference to FIGS.
As shown in FIG. 4, the piercing includes a decorative body 2 provided with a pin 1 and a piercing catch C 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. The pin 1 is received by the piercing catch C on the back side of the ear.
The piercing catch C shown in FIG. 5 is made of a noble metal such as gold or platinum, and is formed by molding the plate-like member c1 shown in FIG. 6, and includes a substantially circular receiving plate portion 3 and a side of the receiving plate portion 3 It consists of a pair of leaf | plate spring part 4 shape | molded integrally by the part. 5 and 6, the same reference numerals are given to portions corresponding to each other.

図６に示す板状部材ｃ１の板バネ部４，４は、それぞれ、その基端４ａから先端４ｂに向かってやや先細りにした形状で、受け板部３の外径方向に突出し、先端４ｂは、板バネ部４の長さ方向に直交する直線状にカットされている。
また、板状部材ｃ１は、受け板部３の中央付近に、ピン挿入孔５を形成するとともに、板バネ部４，４の表側には、プレス加工により線状凹部６，６を形成している。プレス加工によって線状凹部６，６を形成すると、その裏側には線状凸部７，７が形成される。そして、上記線状凹部６，６の深さは、上記装飾体２に設けたピン１の半径以下にしている。 The plate springs 4 and 4 of the plate-like member c1 shown in FIG. 6 are each tapered slightly from the base end 4a toward the tip 4b, and protrude in the outer diameter direction of the receiving plate 3 and the tip 4b is The leaf spring portion 4 is cut in a straight line perpendicular to the length direction.
Further, the plate-like member c1 has a pin insertion hole 5 near the center of the receiving plate part 3, and linear depressions 6 and 6 are formed on the front side of the plate spring parts 4 and 4 by pressing. Yes. When the linear concave portions 6 and 6 are formed by pressing, the linear convex portions 7 and 7 are formed on the back side thereof. And the depth of the said linear recessed parts 6 and 6 is made into the radius of the pin 1 provided in the said decorative body 2 or less.

このような板状部品ｃ１の一対の板バネ部４を、基端４ａ付近で、紙面の裏側である受け板部３の裏側に向けて起立させるとともに、それぞれの先端４ｂが、上記基端４ａの裏側付近に位置するように曲げ加工し、図５に示すピアス用キャッチＣを形成する。このようにカールさせた一対の板バネ部４の間に、上記ピン挿入孔５の中心を通る軸線がちょうど位置するとともに、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。 A pair of leaf springs 4 of such a plate-like component c1 are erected in the vicinity of the base end 4a toward the back side of the receiving plate part 3 which is the back side of the paper surface, and each tip 4b is connected to the base end 4a. 5 to form a piercing catch C shown in FIG. An axis passing through the center of the pin insertion hole 5 is located between the pair of leaf springs 4 curled in this way, and the pair of curled leaf springs 4 are elastic in the direction adjacent to each other. Will be demonstrated.

このようなピアス用キャッチＣに、装飾体２のピン１を挿入すると、ピン１が、隣り合う一対の板バネ部４間であって、上記線状凹部６，６間に挿入される。上記線状凹部６，６によって形成される隙間は、上記ピン１の外径よりも小さいので、上記ピン１が挿入されることによって、板バネ部４，４が弾性に抗して押し広げられ、板バネ部材４，４がピン１を挟持する方向に弾性力を発揮することになる。 When the pin 1 of the decorative body 2 is inserted into such a piercing catch C, the pin 1 is inserted between the pair of adjacent leaf springs 4 and between the linear recesses 6 and 6. Since the gap formed by the linear recesses 6 and 6 is smaller than the outer diameter of the pin 1, insertion of the pin 1 causes the leaf springs 4 and 4 to be expanded against elasticity. The leaf spring members 4 and 4 exhibit an elastic force in the direction in which the pin 1 is sandwiched.

なお、上記板バネ部４，４に線状凹部６，６を形成したのは、以下の理由による。
上記したように、ピアス用キャッチＣは、金やプラチナ等の貴金属の板部材を曲げ加工して板バネ部４，４を形成し、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板部材は一般に柔らかく、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ことがある。特に、高価な材料は、コストの面からも余り厚くすることができない。そのため、このような貴金属製の板部材は、剛性に乏しく、弾性力に限界がある。上記板バネ部４，４の弾性力が不足すると、ピン１の挟持力が弱くなって装飾体２を紛失してしまう危険もある。 The reason why the linear concave portions 6 and 6 are formed in the leaf spring portions 4 and 4 is as follows.
As described above, the piercing catch C is formed by bending a noble metal plate member such as gold or platinum to form the leaf spring portions 4 and 4 so as to exert an elastic force.
However, plate members made of noble metals such as gold and platinum are generally soft, and a sufficient clamping force may not be obtained only by bending. In particular, expensive materials cannot be made too thick in terms of cost. Therefore, such a noble metal plate member has poor rigidity and has a limit in elastic force. If the elastic force of the leaf springs 4 and 4 is insufficient, there is a risk that the pinching force of the pin 1 is weakened and the decorative body 2 is lost.

そこで、このピアス用キャッチＣでは、板バネ部４，４に上記線状凹部６及び線状凸部７によってリブを構成し、板バネ部４，４の剛性を高めて必要な弾性力が得られるようにしている。
また、上記線状凹部６，６間にピン１が挿入されれば、この線状凹部６，６の方向に、ピン１が保持されることになって、ピアス用キャッチＣに対してピン１が傾きにくくなることも期待できる。
登録実用新案第３１０８５２２号公報 Therefore, in this piercing catch C, ribs are formed on the plate spring portions 4 and 4 by the linear concave portions 6 and the linear convex portions 7 to increase the rigidity of the plate spring portions 4 and 4 to obtain a necessary elastic force. I am trying to do it.
Further, if the pin 1 is inserted between the linear recesses 6 and 6, the pin 1 is held in the direction of the linear recesses 6 and 6, and the pin 1 against the piercing catch C Can be expected to be less inclined.
Registered Utility Model No. 3108522

上記従来のピアス用キャッチＣは、カールさせた板バネ部４の先端４ｂが、基端４ａ付近で板バネ部４の裏側に接触するが、ピアス用キャッチＣは小さなパーツなので、板バネ部の先端４ｂ側の表面と基端４ａ付近の裏面とのカーブを完全に一致させることは殆ど不可能である。そのため、先端４ｂ付近で、板バネ部４の表面と基端４ａの裏面とが、面で接触することはなく、図７に示すように、板バネ部４の先端４ｂが板バネ部４の裏側に突き当たるようになる。 In the conventional piercing catch C, the tip 4b of the curled leaf spring portion 4 contacts the back side of the leaf spring portion 4 near the base end 4a, but the piercing catch C is a small part. It is almost impossible to make the curves of the surface on the front end 4b side and the back surface near the base end 4a completely coincide. Therefore, the front surface of the leaf spring portion 4 and the back surface of the base end 4a do not come into contact with each other in the vicinity of the distal end 4b, and the distal end 4b of the leaf spring portion 4 is connected to the leaf spring portion 4 as shown in FIG. It comes to hit the back side.

そして、上記板バネ部４の先端４ｂは直線状にカットされているので、先端４ｂが板バネ部４の裏側に突き当たった場合、図７、図８に示すように、先端４ｂの中央付近のみが、板バネ部４の裏側に突出している線状凸部７に接触することになる。このように、板バネ部４の先端４ｂは、その中央付近が線状凸部７に接触しているので、図８における左右方向、すなわち板バネ部４の幅方向の外力が作用すると、先端４ｂが上記線状凸部７上を滑って、基端４ａに対して上記左右方向にずれてしまうことがある。 And since the front-end | tip 4b of the said leaf | plate spring part 4 is cut linearly, when the front-end | tip 4b collides with the back side of the leaf | plate spring part 4, as shown in FIG. 7, FIG. 8, only the center vicinity of the front-end | tip 4b is shown. However, it comes into contact with the linear convex portion 7 protruding to the back side of the leaf spring portion 4. Thus, since the tip 4b of the leaf spring portion 4 is in contact with the linear convex portion 7 near the center, if an external force in the left-right direction in FIG. 4b may slide on the linear convex portion 7 and shift in the left-right direction with respect to the base end 4a.

特に、上記ピン１の挿入方向は、図８における左右方向なので、板バネ部４，４間にピン１が挿入されると、上記左右方向の力が作用し、この力によって先端４ｂがずれて板バネ部材４の形状が変わってしまうことがある。
このように、ピン１を挿入した状態で、板バネ部材４が変形してしまうと、弾性力によってピン１を確実に保持できなくなる。また、ピン１の抜き差しによって、変形を繰り返すと、板バネ部４が破損してしまうこともある。 In particular, since the insertion direction of the pin 1 is the left-right direction in FIG. 8, when the pin 1 is inserted between the leaf spring portions 4, 4, the left-right force acts, and the tip 4 b is displaced by this force. The shape of the leaf spring member 4 may change.
Thus, if the leaf spring member 4 is deformed in a state where the pin 1 is inserted, the pin 1 cannot be reliably held by the elastic force. Further, if the deformation is repeated by inserting and removing the pin 1, the leaf spring portion 4 may be damaged.

また、上記線状凹部６と線状凸部７とは、同一板部材の表裏に一体的に形成されるものので、板部材に厚みがあることから、線状凸部７の幅は線状凹部６の幅よりも大きくなっている。そのため、仮に、上記先端４ｂ付近で、その表面が基端４ａ付近の裏面と面で接触したとしても、上記線状凸部７が線状凹部６に、ぴったりはまることはなく、図８の左右方向、すなわち、板バネ部４の幅方向の外力が作用すれば、先端４ｂが、上記線状凸部７上を滑ってずれてしまい、板バネ部材４が変形してしまう。
この発明の目的は、ピンの抜き差しによって板バネ部に外力が作用しても、板バネ部が変形することがなく、ピンを確実に保持できて、しかも耐久性の高いピアス用キャッチを提供することである。 Moreover, since the said linear recessed part 6 and the linear convex part 7 are integrally formed in the front and back of the same board member, since the board member has thickness, the width | variety of the linear convex part 7 is linear. It is larger than the width of the recess 6. Therefore, even if the front surface is in contact with the back surface near the base end 4a in the vicinity of the distal end 4b, the linear convex portion 7 does not fit into the linear concave portion 6, and the right and left in FIG. If an external force in the direction, that is, the width direction of the leaf spring portion 4 is applied, the tip 4b slips on the linear convex portion 7 and the leaf spring member 4 is deformed.
An object of the present invention is to provide a piercing catch that can reliably hold a pin even when an external force is applied to the leaf spring portion by inserting and removing the pin, can reliably hold the pin, and has high durability. That is.

この発明は、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、この一対の板バネ部の表側であって先端から基端あるいは受け板部まで連続する線状凹部と、この線状凹部によってその裏側に形成される線状凸部とを備え、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、このピンが上記一対の板バネ部に形成した線状凹部内に位置し、カールさせた一対の板バネ部の弾性力によって挟持される構成にするとともに、上記一対の板バネ部の先端には、その幅方向中央に切り欠きを形成し、この切り欠きが上記受け板部または板バネ部の裏側の線状凸部をまたいで板バネ部の先端を、受け板部または板バネ部の裏面に接触させることを特徴とする。 The present invention includes a receiving plate portion in which a pin insertion hole is formed, a pair of leaf spring portions that are molded integrally with the receiving plate portion, raised toward the back side of the receiving plate portion, and curled by bending, A linear concave portion that is continuous from the front end to the base end or the receiving plate portion on the front side of the pair of leaf spring portions, and a linear convex portion that is formed on the back side by the linear concave portion, and is provided on the decorative body When the pin is inserted into the pin insertion hole from the front side of the receiving plate portion, the pin is located in a linear recess formed in the pair of leaf spring portions, and the elastic force of the curled pair of leaf spring portions is In addition to being configured to be sandwiched, a notch is formed at the center of the pair of leaf springs in the width direction, and this notch forms a linear protrusion on the back side of the backing plate or leaf spring. Also straddle the end of the leaf spring with the receiving plate or plate bar Wherein the contacting the rear surface of the part.

この発明によれば、ピンの抜き差しなどによって、板バネ部に外力が作用しても、板バネ部の先端がずれて板バネ部が変形することがない。従って、板バネ部の弾性力が維持され、一対の板バネ部による挟持力でピンを確実に保持することができる。
また、ピンの抜き差しによって変形を繰り返すことがないので、板バネ部が破損しやすくなることもなく、ピアス用キャッチの耐久性も向上する。 According to this invention, even if an external force is applied to the leaf spring portion by inserting / removing pins, the tip of the leaf spring portion is not displaced and the leaf spring portion is not deformed. Therefore, the elastic force of the leaf spring portion is maintained, and the pin can be reliably held by the clamping force of the pair of leaf spring portions.
In addition, since the deformation is not repeated by inserting and removing the pin, the leaf spring portion is not easily damaged, and the durability of the piercing catch is improved.

図１〜図３に、この発明の実施形態を示す。
この実施形態のピアス用キャッチも、外観は、図５に示す従来のピアス用キャッチと同様なので、以下の説明にもこの図５を参照する。また、この実施形態のピアス用キャッチにおいて、従来と同様の構成要素には、同じ符号を用いて説明する。
この実施形態のピアス用キャッチは、図１に示す板状部材ｃ２で形成するものである。この板状部材ｃ２は、上記従来の板状部材ｃ１と同様に貴金属製の板部材を型抜きして形成したものであり、受け板部３の両側に一対の板バネ部４，４を備えている。そして、各板バネ部４には、表側に線状凹部６、裏側に線状凸部７を形成している。
なお、図１において紙面の表側を板部バネ部４の表側、紙面の裏側に対応する側を板バネ部４の裏側ということにする。 1 to 3 show an embodiment of the present invention.
Since the appearance of the piercing catch of this embodiment is the same as that of the conventional piercing catch shown in FIG. 5, FIG. 5 is also referred to in the following description. Moreover, in the piercing catch of this embodiment, the same reference numerals are used for the same constituent elements as in the prior art.
The piercing catch of this embodiment is formed by a plate-like member c2 shown in FIG. The plate-like member c2 is formed by punching a noble metal plate member in the same manner as the conventional plate-like member c1 and includes a pair of plate spring portions 4, 4 on both sides of the receiving plate portion 3. ing. And in each leaf | plate spring part 4, the linear recessed part 6 is formed in the front side, and the linear convex part 7 is formed in the back side.
In FIG. 1, the front side of the paper surface is referred to as the front side of the plate spring portion 4 and the side corresponding to the back side of the paper surface is referred to as the back side of the plate spring portion 4.

ただし、この実施形態の板状部材ｃ２は、板バネ部４の先端４ｂに、切り欠き８を形成している点が、上記従来の板状部材ｃ１と異なる。この切り欠き８はその幅及び深さを、上記線状凸部７の幅及び高さとほぼ同じにしている。
このような板状部材ｃ２の一対の板バネ部４を、基端４ａ付近で、受け板部３の裏側に向けて起立させるとともに、それぞれの先端４ｂが、上記基端４ａの裏側付近に位置するように曲げ加工し、図５に示すピアス用キャッチＣを形成する。このようにカールさせた一対の板バネ部４の間に、上記ピン挿入孔５に挿入したピン１（図４参照）が、カールさせた一対の板バネ部４の弾性力によって挟持されることになる。 However, the plate-like member c2 of this embodiment is different from the conventional plate-like member c1 in that a notch 8 is formed at the tip 4b of the leaf spring portion 4. The notches 8 have substantially the same width and depth as the width and height of the linear protrusion 7.
The pair of leaf springs 4 of the plate-like member c2 is raised near the base end 4a toward the back side of the receiving plate part 3, and each tip 4b is positioned near the back side of the base end 4a. The piercing catch C shown in FIG. 5 is formed by bending. The pin 1 inserted into the pin insertion hole 5 (see FIG. 4) is sandwiched between the pair of leaf springs 4 curled in this way by the elastic force of the pair of leaf springs 4 curled. become.

上記板状部材ｃ２によって形成されたピアス用キャッチも、板バネ部４の先端４ｂが基端４ａ付近の裏側に突き当たることになるが、先端４ｂには切り欠き８を形成しているので、この切り欠き８が板バネ部４の裏側に突出している線状凸部７をまたいで、その両側が板バネ部４の裏面に接触している。図２，図３に示すように、上記切り欠き８内に、上記凸部７が収まっているので、図３における左右方向に外力が作用しても、先端４ｂが基端４ａ側の線状凸部７上を滑って、ずれてしまうようなことはない。つまり、ピン１を挿入したときに、板バネ部４が変形することがないということである。そのため、板バネ部４が破損しやすくなるということもない。
従って、この実施形態のピアスキャッチは、ピン１を確実に保持できるとともに、耐久性も高くなる。 In the piercing catch formed by the plate-like member c2, the distal end 4b of the leaf spring portion 4 abuts on the back side near the base end 4a, but the notch 8 is formed in the distal end 4b. The notch 8 straddles the linear convex portion 7 protruding to the back side of the leaf spring portion 4, and both sides thereof are in contact with the back surface of the leaf spring portion 4. As shown in FIGS. 2 and 3, since the convex portion 7 is accommodated in the notch 8, the distal end 4b is linear on the base end 4a side even if an external force acts in the left-right direction in FIG. There is no such thing as slipping on the projection 7 and shifting. That is, when the pin 1 is inserted, the leaf spring portion 4 is not deformed. Therefore, the leaf spring portion 4 is not easily damaged.
Therefore, the piercing catch of this embodiment can reliably hold the pin 1 and also has high durability.

なお、上記実施形態では、板バネ部４の先端４ｂに形成した切り欠き８の幅及び深さを、上記線状凸部７の幅及び高さと同等にしたが、切り欠き８の幅及び深さは、線状凸部７の幅及び高さ以上であればよい。ただし、板バネ部４の先端４ｂは、切り欠きの幅内で幅方向にずれる可能性があるので、切り欠き８の幅は、線状凸部７の幅に近いほどよい。
なお、上記実施形態では、板バネ部４の先端４ｂを基端４ａの裏側に接触させているが、上記先端４ｂは、受け板部３の裏面に接触させるようにしてもよい。この場合にも、受け板部３の裏側に形成された線状凸部７を切り欠き８がまたぐように構成する。これにより、板バネ部４の先端４ｂが板バネ部４の幅方向にずれて変形することを防止できる。 In the above embodiment, the width and depth of the notch 8 formed at the tip 4b of the leaf spring portion 4 are made equal to the width and height of the linear convex portion 7. However, the width and depth of the notch 8 are the same. The height may be equal to or greater than the width and height of the linear protrusion 7. However, since the tip 4b of the leaf spring portion 4 may be shifted in the width direction within the width of the cutout, the width of the cutout 8 is preferably closer to the width of the linear convex portion 7.
In the above embodiment, the distal end 4 b of the leaf spring portion 4 is brought into contact with the back side of the base end 4 a, but the distal end 4 b may be brought into contact with the back surface of the receiving plate portion 3. Also in this case, it is configured such that the notch 8 straddles the linear convex portion 7 formed on the back side of the receiving plate portion 3. Thereby, it can prevent that the front-end | tip 4b of the leaf | plate spring part 4 shifts | deviates to a width direction of the leaf | plate spring part 4, and deform | transforms.
