Abstract

ピン留めと、先端部付近に留め部を設けたピンからなる留め具であって、ピン留めは薄板状バネ材の長手方向の中央部を折曲げ成形することにより、頂部とその両側の１対の傾斜部とからなる三角形の側面形状を持たせ、頂部にはピンを挿入するためのピン留め孔を設けると共に、ピン留め孔における長手方向の周縁部からは、ピン留め孔に挿入されたピンの留め部に係合する長さの１対の留め部材を傾斜部と同一方向へ突出させている留め具。この発明により、ピン挿入力は小さいがピン抜き力は大きく、しかも簡単な操作でピン留め状態を解除できるピン留め式の留め具が提供される。A pin fastener and a fastener having a pin provided in the vicinity of the tip, wherein the pin clamp is formed by bending a central portion in the longitudinal direction of the thin plate-like spring material to form a pair of the top portion and both sides thereof. The pin is inserted into the pin-clamping hole from the peripheral edge in the longitudinal direction of the pin-clamping hole. The fastener which makes the pair of fastening member of the length engaged with the fastening part protrude in the same direction as an inclination part. According to the present invention, there is provided a pinning type fastener that has a small pin insertion force but a large pin pulling force and can release the pinned state by a simple operation.

Description

本発明は、ピンとピン留めからなるピン留め式の留め具に関する。本発明は、特に好ましくは、タイタック、ピンブローチ、ピアス、ネックレス等の装飾品の留め具に適用されるが、装飾品以外の比較的小さなサイズの各種の物品の留め具にも適用される。     The present invention relates to a pin-type fastener comprising a pin and a pin. The present invention is particularly preferably applied to fasteners for ornaments such as tie tacks, pin broaches, earrings, necklaces, etc., but also to fasteners for various articles of relatively small size other than ornaments.

従来、例えばピアス等の身体装飾品におけるピン留め式の留め具は、第１図の（ａ）に簡単に示すように、先端部付近に周溝２を有するピン１をピン留め具（図示省略）に挿入し、ピン留め具の留め部材３を周溝２に係合する位置に進入させて固定する構造が一般的である。そして、適宜な操作により留め部材３を周溝２から離脱させることにより、ピン留め具からピン１を抜くことができるようになっている。
特に、近年のピン留め式の留め具においては、ピンの周溝に対する留め部材の進入と離脱とを、弾性的な変形機能を持つバネ材を利用して行う構造が多い。通常のピン留め具は小さなサイズであるため、バネ材を利用するピン留め機構によって留め具の構造を簡素化することは、合理的である。
〔文献１〕 特開２００２−３３６０１４
第１の従来技術として、上記の文献１において提案された耳飾り（ピアス）の留め具では、第２図の（ａ）に示すように、基板４の中央部であるガイド部５に孔６を設けている。そして孔６には筒状のガイドピース７を嵌め込み、このガイドピース７の貫通孔８からピンを挿入するようになっている。一方、基板４の周囲部にはガイド溝１０を伴う弾性片９を形成している。弾性片９は、基板４の裏側へゆるやかに曲げられて、ループ部１１を構成している。つまり、第２図の（ｂ）に示すようにピン１２を基板４のガイド部５側から挿入し、その周溝１３にループ部１１を食い込ませて、ピン１２を留める構造である。
次に、第２の従来技術として、第３図の（ａ）及び（ｂ）に断面図で示すピン留め具も提案されている。このピン留め具１４においては、全体的に円形又は楕円形であるカバー１５の内部に、弾性的に変形可能な材料からなる１対の留め部材１６が収納されている。これらの留め部材１６は、中央のピン挿入部１７を中心としてほぼ対称に構成されており、それぞれ図示する形状のピン留めアーム１８と押さえアーム１９とを備えている。
ピン留め状態においては、第３図の（ａ）に示すように双方の留め部材１６の押さえアーム１９がそれぞれ他方の留め部材１６を反対方向へ押しつけ、その結果、一対のピン留めアーム１８がピン挿入部１７の方向へ押付けられている。そのため、ピン挿入部１７にあるピン（図示省略）は１対のピン止めアーム１８によって留められる。
ピン留め具１４からピンを抜く場合は、留め部材１６からカバー１５の外側へ突出したボタン部２０を中央方向へ押し込む。すると、第３図の（ｂ）に示すように、１対のピン留めアーム１８がそれぞれ押さえアーム１９の付勢力に抗してピンから離脱し、ピン留め状態が解除される。
しかし、上記した第１及び第２の従来技術においては、ピン留め具の留め部材（即ち、第１の従来技術におけるループ部１１、第２の従来技術におけるピン留めアーム１８）がピンの周溝に対して径方向（真横の方向）から当接されると言う構造である。このような構造の場合、ピン挿入力（ピン留め具に対するピンの挿入時に要する力）と、ピン抜き力（留め部材の離脱操作なしにピンが抜けるために要する力）とは、基本的に同じ強さとなる。従って、ピン留め操作の容易さを考慮してピン挿入力を小さく設定すると、ピン抜き力も小さくなる。その結果、例えばピアスが髪の毛などに引掛かることによって、ピン抜き操作を行っていないのにピンが抜けてしまう恐れがある。そのため、知らぬ間にピアスが脱落したり、ピアスを紛失してしまったりすることが少なくない。
次に、前記した第１の従来技術においては、非常に小さな筒状ガイドピース７を製造し、かつ、これを基板４の孔６に嵌め込む必要がある。更に、この嵌め込み部分を溶接等の手段により固定する必要がある。又、前記した第２の従来技術においては、非常に小さくて複雑な形状の１対のピン留め具１４を正確に製造し、カバー１５に対して組付ける必要がある。従って、これらの製造コスト及び組付けコストの増大を余儀なくされる。2. Description of the Related Art Conventionally, pin-type fasteners for body ornaments such as earrings, for example, as shown in FIG. 1 (a), pin 1 having a peripheral groove 2 in the vicinity of the tip portion is not shown. ), And the fixing member 3 of the pin fastener is moved into a position where it engages with the circumferential groove 2 and is fixed. Then, the pin 1 can be removed from the pin fastener by detaching the fastening member 3 from the circumferential groove 2 by an appropriate operation.
In particular, in recent pinning-type fasteners, there are many structures in which the fastening member enters and leaves the peripheral groove of the pin using a spring material having an elastic deformation function. Since ordinary pin fasteners are small in size, it is reasonable to simplify the fastener structure with a pinning mechanism that utilizes spring material.
[Reference 1] JP 2002-336014 A
As a first prior art, in the earring fastener proposed in the above-mentioned document 1, as shown in FIG. 2 (a), a hole 6 is formed in the guide portion 5 which is the central portion of the substrate 4. Provided. A cylindrical guide piece 7 is fitted into the hole 6, and a pin is inserted from the through hole 8 of the guide piece 7. On the other hand, an elastic piece 9 with a guide groove 10 is formed around the substrate 4. The elastic piece 9 is gently bent toward the back side of the substrate 4 to form a loop portion 11. That is, as shown in FIG. 2 (b), the pin 12 is inserted from the guide part 5 side of the substrate 4, and the loop part 11 is bitten into the peripheral groove 13 so that the pin 12 is fastened.
Next, as a second prior art, a pin fastener shown in cross-sectional views in FIGS. 3 (a) and 3 (b) has also been proposed. In this pin fastener 14, a pair of fastening members 16 made of an elastically deformable material are housed inside a cover 15 that is generally circular or elliptical. These fastening members 16 are configured substantially symmetrically with a center pin insertion portion 17 as a center, and are provided with a pin fastening arm 18 and a holding arm 19 each having a shape shown in the drawing.
In the pinned state, as shown in FIG. 3 (a), the holding arms 19 of the two fastening members 16 respectively press the other fastening member 16 in the opposite direction. As a result, the pair of pinning arms 18 are pinned. It is pressed in the direction of the insertion portion 17. Therefore, the pins (not shown) in the pin insertion portion 17 are fastened by a pair of pinning arms 18.
When the pin is pulled out from the pin fastener 14, the button part 20 protruding from the fastening member 16 to the outside of the cover 15 is pushed in the center direction. Then, as shown in FIG. 3 (b), the pair of pinning arms 18 are separated from the pins against the urging force of the pressing arm 19, and the pinned state is released.
However, in the first and second prior arts described above, the fastening member of the pin fastener (that is, the loop portion 11 in the first prior art and the pinning arm 18 in the second prior art) is the peripheral groove of the pin. It is the structure said to contact | abut with respect to the radial direction (right side direction). In the case of such a structure, the pin insertion force (the force required when inserting the pin into the pin fastener) and the pin pulling force (the force required for the pin to come out without the operation of removing the fastening member) are basically the same. Become strength. Accordingly, if the pin insertion force is set small in consideration of the ease of pinning operation, the pin pulling force is also reduced. As a result, for example, when the piercing is caught on the hair or the like, the pin may come off even though the pinning operation is not performed. For this reason, it is not uncommon for piercings to drop or to be lost without knowing it.
Next, in the first prior art described above, it is necessary to manufacture a very small cylindrical guide piece 7 and fit it into the hole 6 of the substrate 4. Furthermore, it is necessary to fix the fitting portion by means such as welding. In the second prior art described above, a pair of pin fasteners 14 having a very small and complicated shape must be accurately manufactured and assembled to the cover 15. Therefore, these manufacturing costs and assembly costs are inevitably increased.

本発明の目的は、ピン留め式の留め具であって、ピン挿入力は小さいがピン抜き力は大きく、しかも簡単な操作によってピン留め状態を容易に解除できる留め具を提供することである。本発明の他の目的は、このような留め具の構造をシンプルにして、その製造コストを低減することである。
（第１発明）
本願の第１発明は、ピン留めと、先端部付近に周溝、凹部又は凸部からなる留め部を設けたピンとからなり、前記ピン留めの留め部材を前記ピンの留め部に係合させてピンを留め、この留め部材を前記留め部から離脱させてピン留め状態を解除する留め具であって、
前記ピン留めは、薄板状バネ材の長手方向の中央部を鋭角状又は円弧状に折曲げ成形して、頂部とその両側の１対の傾斜部からなる三角形の側面形状を持たせたものであり、
前記頂部にはピンを挿入するためのピン留め孔を設けると共に、このピン留め孔における長手方向の周縁部からは、ピン留め孔に挿入されたピンの留め部に係合する長さの１対の前記留め部材を傾斜部と同一方向へ突出させており、
更に、前記１対の傾斜部の長手方向端部を前記三角形の側面形状の底辺に沿う方向へ折曲げ成形することにより、ピン留めの三角形の側面形状を弾性的に圧縮変形させると言うピン留め状態解除操作に対するストッパを形成させた留め具である。
第１発明に係る留め具においては、留め具のピン留めの際、ピン留めの三角形の形状における底辺側から、頂部のピン留め孔に対してピンを挿入する。その時、ピンはピン留め孔に突出した１対の留め部材を弾性的に変形させて押退けながら挿入される。そして、ピンの留め部が留め部材の突出位置に到ると、留め部材がピンの留め部に係合し、ピン留めが完了する。ピンの留め部が周溝又は凹部からなる場合、留め部材が留め部へ進入する際には軽い打撃音を発生するので、ピン留めの完了を容易に確認できる。１対の留め部材は傾斜部と同一方向へ突出しているため、ピンの挿入に対する抵抗は弱く、ピン留め状態にあるピンの抜けに対する抵抗は極めて強い。即ち、ピン挿入力は小さくピン抜き力は大きい。
ピン留め状態を解除したい場合は、ピン留めの１対の傾斜部の両端部を親指と人指し指とで摘み、端部間を圧縮するように力を加える（ピン留めの三角形の側面形状を弾性的に圧縮変形させる）だけで良い。この操作により、ピン留めの頂部がより鋭く曲がるように弾性的変形を起こし、傾斜部から突出した１対の留め部材が互いに開く方向へ変位する。従って、留め部材がピンの留め部から離脱し、ピン留めからピンを抜くことができる。
そして、ピン留めの１対の傾斜部の長手方向端部を三角形の側面形状の底辺に沿う方向へ折曲げ成形してストッパを形成しているので、ピン留め状態解除操作においては、ストッパがピンに当たるまで、ピン留めを圧縮変形させれば良い。その結果、ピン留め状態解除操作が簡単かつ確実になり、しかもピン留めを過剰に圧縮変形させることによる頂部の破損や、頂部の弾性的変形能の劣化を有効に防止することができる。
（第２発明）
本願の第２発明は、ピン留めと、先端部付近に周溝、凹部又は凸部からなる留め部を設けたピンとからなり、前記ピン留めの留め部材を前記ピンの留め部に係合させてピンを留め、この留め部材を前記留め部から離脱させてピン留め状態を解除する留め具であって、
前記ピン留めは薄板状バネ材の長手方向の中央部を鋭角状又は円弧状に折曲げ成形することにより、頂部とその両側の１対の傾斜部からなる三角形の側面形状を持たせ、
前記頂部にはピンを挿入するためのピン留め孔を設けると共に、このピン留め孔における長手方向の周縁部からは、ピン留め孔に挿入されたピンの留め部に係合する長さの１対の前記留め部材を傾斜部と同一方向へ突出させ、
更に、前記１対の傾斜部の長手方向端部の一方又は双方を前記三角形の側面形状の底辺に沿う方向へ折曲げ成形して底辺部を形成すると共に、この底辺部における前記ピン留め孔の直下の部分には、ピンを通過させるためのピン通孔を設けた留め具である。
第２発明においては、上記の第１発明におけるストッパに基づく作用・効果を除き、第１発明と同じ作用・効果が得られる。更に、次の作用・効果がある。即ち、ピン留め状態にあるピンとピン留めは、頂部のピン留め孔と底辺部のピン通孔との２点において、互いに動きを拘束される。そのため、ピン留めがピンに対して揺れ動かないので、ピン留め状態の留め具が不安定に揺れ動かない。
（第３発明）
本願の第３発明は、前記第２発明における傾斜部の長手方向端部の双方に前記底辺部を設ける場合において、その一方の底辺部に設けられ他方の底辺部の方向へ折曲げ成形された耳片により、双方の底辺部を、長手方向への相対的なスライド動作が可能な状態において互いに拘束させた留め具である。
第３発明においては、１対の傾斜部から折曲げ成形した双方の底辺部が耳片によって互いに拘束されるので、ピン留めの構造的な強度が高い。なお、双方の底辺部は長手方向への相対的なスライド動作が可能であるため、上記の耳片を設けても、第１発明で前記したようなピン留めの弾性的変形を伴うピン留め状態の解除操作に支障はない。
（第４発明）
本願の第４発明は、ピン留めと、先端部付近に周溝、凹部又は凸部からなる留め部を設けたピンとからなり、前記ピン留めの留め部材を前記ピンの留め部に係合させてピンを留め、この留め部材を前記留め部から離脱させてピン留め状態を解除する留め具であって、
前記ピン留めは薄板状バネ材の長手方向の中央部を鋭角状又は円弧状に折曲げ成形することにより、頂部とその両側の１対の傾斜部からなる三角形の側面形状を持たせ、
前記頂部にはピンを挿入するためのピン留め孔を設けると共に、前記１対の傾斜部からはそれぞれ短手方向へ折返し片を突出させて前記傾斜部の表面（前記三角形の外側の面）に重ねるように折曲げ成形し、これら１対の折返し片からは、ピン留め孔に挿入されたピンの留め部に係合する長さの前記留め部材をピン留め孔の中心に向かって傾斜部と同一方向へ突出させた留め具である。
第４発明に係る留め具においては、第１発明の場合と同様、薄板状バネ材を加工して簡単にピン留めを製造でき、しかも従来のピン留めに比較してシンプルな構造であるため、低コストの留め具を提供することができる。
又、第１発明の場合に比較してピン留めの構造がやや複雑であるが、ピン留め孔と留め部材を薄板状バネ材の同じ部分に形成する必要がないため、ピン留め孔と留め部材とを形成する工程が容易である。
（第５発明）
本願の第５発明は、前記第４発明における折返し片の短手方向先端部に設けられ傾斜部の方向へ折曲げ成形された耳片により、折返し片の先端部を傾斜部に対して密着させた留め具である。
傾斜部の表面に重ねるように折曲げ成形した折返し片は、留め部材を備えているので、ピンをピン留めに挿入する操作を行うたびに、折返し片を傾斜部の表面から起き上がらせようとする力を受ける。折返し片が傾斜部の表面から起き上がってしまうと、良好なピン留め状態を実現できなくなる。従って、第５発明のように耳片を用いて折返し片を傾斜部に対して密着させておけば、このような不具合を完全に防止できる。
（第６発明）
本願の第６発明は、ピン留めと、先端部付近に周溝、凹部又は凸部からなる留め部を設けたピンとからなり、前記ピン留めの留め部材を前記ピンの留め部に係合させてピンを留め、この留め部材を前記留め部から離脱させてピン留め状態を解除する留め具であって、
前記ピン留めは薄板状バネ材の長手方向の中央部を鋭角状又は円弧状に折曲げ成形することにより、頂部とその両側の１対の傾斜部からなる三角形の側面形状を持たせ、
前記頂部にはピンを挿入するためのピン留め孔を設けると共に、前記１対の傾斜部からはそれぞれ短手方向へ折返し片を突出させて前記傾斜部の表面（前記三角形の外側の面）に重ねるように折曲げ成形し、これら１対の折返し片からは、ピン留め孔に挿入されたピンの留め部に係合する長さの前記留め部材をピン留め孔の中心に向かって傾斜部と同一方向へ突出させ、
更に、前記１対の傾斜部の長手方向端部の一方又は双方を前記三角形の側面形状の底辺に沿う方向へ折曲げ成形して底辺部を形成すると共に、この底辺部における前記ピン留め孔の直下の部分には、ピンを通過させるためのピン通孔を設けた留め具である。
第６発明においては、上記の第５発明と同じ作用・効果が得られる点に加え、次の作用・効果がある。即ち、ピン留め状態にあるピンとピン留めは、頂部のピン留め孔と底辺部のピン通孔との２点において、互いに動きを拘束される。そのため、ピン留めがピンに対して揺れ動かないので、ピン留め状態の留め具が不安定に揺れ動かない。
（第７発明）
本願の第７発明は、前記第６発明における折返し片の短手方向先端部に設けられ前記傾斜部の方向へ折曲げ成形された耳片により、折返し片の先端部を傾斜部に対して密着させた留め具である。
傾斜部の表面に重ねるように折曲げ成形した折返し片は、留め部材を備えているので、ピンをピン留めに挿入する操作を行うたびに、折返し片を傾斜部の表面から起き上がらせようとする力を受ける。折返し片が傾斜部の表面がら起き上がってしまうと、良好なピン留め状態を実現できなくなる。従って、第７発明のように耳片を用いて折返し片を傾斜部に対して密着させておけば、このような不具合を完全に防止できる。
（第８発明）
本願の第８発明は、前記第６発明又は第７発明における傾斜部の長手方向端部の双方に前記底辺部を設ける場合において、その一方の底辺部に設けられ他方の底辺部の方向へ折曲げ成形された耳片により、双方の底辺部を、長手方向への相対的なスライド動作が可能な状態において互いに拘束させた留め具である。
第８発明においては、１対の傾斜部から折曲げ成形した双方の底辺部が耳片によって互いに拘束されるので、ピン留めの構造的な強度が高い。なお、双方の底辺部は長手方向への相対的なスライド動作が可能であるため、上記の耳片を設けても、第１発明で前記したようなピン留めの弾性的変形を伴うピン留め状態の解除操作に支障はない。
（第９発明）
本願の第９発明は、ピン留めと、先端部付近に周溝、凹部又は凸部からなる留め部を設けたピンとからなり、前記ピン留めの留め部材を前記ピンの留め部に係合させてピンを留め、この留め部材を前記留め部から離脱させてピン留め状態を解除する留め具であって、
前記ピン留めは薄板状バネ材の長手方向の中央部を鋭角状又は円弧状に折曲げ成形することにより、頂部とその両側の１対の傾斜部からなる三角形の側面形状を持たせ、
前記頂部にはピンを挿入するためのピン留め孔を設けると共に、このピン留め孔における長手方向の周縁部からは、ピン留め孔に挿入されたピンの留め部に係合する長さの１対の前記留め部材を傾斜部と同一方向へ突出させ、
更に、前記１対の傾斜部の一方の長手方向端部を前記三角形の側面形状の底辺に沿う方向へ折曲げ成形して底辺部を形成すると共に、この底辺部における前記ピン留め孔の直下の部分には、ピンを通過させるためのピン通孔を設け、
又、前記１対の傾斜部の他方の長手方向端部を前記三角形の頂部方向へ折曲げ成形して立上げ部を形成すると共に、この立上げ部の先端に設けた耳片を折曲げ成形して、前記ピン留め孔に挿入されたピンの先端を囲むシェルター部材を形成した留め具である。
第９発明に係る留め具においては、第１発明の場合と同様、薄板状バネ材を加工して簡単にピン留めを製造でき、しかも従来のピン留めに比較してシンプルな構造であるため、低コストの留め具を提供することができる。更に第９発明においては、次の作用・効果がある。
即ち、第１点として、ピン留め状態にあるピンとピン留めは、頂部のピン留め孔と底辺部のピン通孔との２点において互いに動きを拘束される。そのため、ピン留めがピンに対して揺れ動かないので、ピン留め状態の留め具が不安定に揺れ動かない。
第２点として、立上げ部を設けて、この立上げ部に、ピン留め孔に挿入されたピンの先端を囲むシェルター部材を形成したので、ピン留め状態にあるピンの先端がシェルター部材の内部に収容される。その結果、留め具を不注意に扱ってピンの尖った先端が装着者の指や皮膚に刺さると言う事故を防止することができる。
（第１０発明）
本願の第１０発明は、ピン留めと、先端部付近に周溝、凹部又は凸部からなる留め部を設けたピンとからなり、前記ピン留めの留め部材を前記ピンの留め部に係合させてピンを留め、この留め部材を前記留め部から離脱させてピン留め状態を解除する留め具であって、
前記ピン留めは薄板状バネ材の長手方向の中央部を鋭角状又は円弧状に折曲げ成形することにより、頂部とその両側の１対の傾斜部からなる三角形の側面形状を持たせ、
前記頂部にはピンを挿入するためのピン留め孔を設けると共に、前記１対の傾斜部の長手方向端部を前記傾斜部の表面（前記三角形の外側の面）又は裏面（前記三角形の内側の面）に重ねるように折曲げ成形してピン留め片を形成し、これら１対のピン留め片の長手方向端部からは、ピン留め孔に挿入されたピンの留め部に係合する長さの前記留め部材をピン留め孔の中心に向かって傾斜部と同一方向へ突出させた留め具である。
第１０発明に係る留め具においては、第１発明の場合と同様、薄板状バネ材を加工して簡単にピン留めを製造でき、しかも従来のピン留めに比較してシンプルな構造であるため、低コストの留め具を提供することができる。
又、第１発明の場合に比較してピン留めの構造がやや複雑であるが、ピン留め孔と留め部材を薄板状バネ材の同じ部分に形成する必要がないため、ピン留め孔と留め部材とを形成する工程が容易である。
（第１１発明）
本願の第１１発明は、前記第１０発明におけるピン留め片を傾斜部の表面に重ねるように折曲げ成形する場合において、ピン留め片の短手方向に設けられ傾斜部の方向へ折曲げ成形された耳片により、ピン留め片を傾斜部に対して密着させた留め具である。
傾斜部の表面に重ねるように折曲げ成形したピン留め片は、留め部材を備えているので、ピンをピン留めに挿入する操作を行うたびに、ピン留め片を傾斜部の表面から起き上がらせようとする力を受ける。ピン留め片が傾斜部の表面から起き上がってしまうと、良好なピン留め状態を実現できなくなる。従って、第１１発明のように耳片を用いてピン留め片を傾斜部に対して密着させておけば、このような不具合を完全に防止できる。
（第１２発明）
本願の第１２発明は、ピン留めと、先端部付近に周溝、凹部又は凸部からなる留め部を設けたピンとからなり、前記ピン留めの留め部材を前記ピンの留め部に係合させてピンを留め、この留め部材を前記留め部から離脱させてピン留め状態を解除する留め具であって、
前記ピン留めを、バネ部材と、前記留め部材を備える留めベースとによって構成し、
前記バネ部材は、鋭角状又は円弧状に曲がった形状を有する頂部と、その両側の１対の直線状の傾斜部からなる三角形の側面形状を持ち、かつ、前記頂部にはピンを挿入するためのピン留め孔を備え、
前記１対の傾斜部の一方又は双方に前記留めベースを固定することにより、留めベースの留め部材が前記傾斜部と同一方向へかつ前記ピン留め孔に挿入されたピンの留め部に係合する長さに突出するように構成した留め具である。
第１２発明に係る装飾品の留め具においては、ピン留めを構成するバネ部材と、留め部材を備える留めベースとを一体に成形する必要はない。又、バネ部材の構成材料は、弾性的に変形し得る材料であれば良く、折曲げ加工が可能な材料を用いる必要がない。これらの点から、相対的に材料の選定や留め具の設計が容易である。又、ピン留めの構造がシンプルであるため、低コストの留め具を提供できる。
留め具のピン留めの際には、バネ部材の三角形の形状における底辺側から、頂部のピン留め孔に対してピンを挿入する。その時、ピンはピン留め孔に突出した留め部材に対して、これを押退けようとする力を及ぼす。この力は、留め部材を備える留めベースを通じてバネ部材に伝達され、バネ部材が幾分の変形を起こすことにより、ピンが留め部材を押退けてピン留め孔に挿入される。
そして、ピンの留め部が留め部材の突出位置に到ると、上記したバネ部材の幾分の変形が元に戻り、その結果として、留め部材の先端部が元の突出位置に復帰してピンの留め部に係合し、ピン留めが完了する。ピンの留め部が周溝又は凹部である場合、留め部材が留め部に係合する際には軽い打撃音を発生するので、ピン留めの完了を容易に確認できる。留め部材は傾斜部と同一方向へ突出しているため、ピンの挿入に対する抵抗は弱く、ピン留め状態にあるピンの抜けに対する抵抗は極めて強い。即ち、ピン挿入力は小さく、ピン抜き力は大きい。
ピン留め状態を解除したい場合は、バネ部材の１対の傾斜部の両端部を親指と人指し指とで摘み、端部間を圧縮するように力を加えるだけで良い。この操作により、バネ部材の頂部がより鋭く曲がるように弾性的変形を起こし、傾斜部から突出した１対の留め部材が互いに開く方向へ変位する。従って、留め部材がピンの留め部から離脱し、ピン留めからピンを抜くことができる。
（第１３発明）
本願の第１３発明は、ピン留めと、先端部付近に周溝、凹部又は凸部からなる留め部を設けたピンとからなり、前記ピン留めの留め部材を前記ピンの留め部に係合させてピンを留め、この留め部材を前記留め部から離脱させてピン留め状態を解除する留め具であって、
前記ピン留めを、バネ部材と、前記留め部材を備える留めベースとによって構成し、
前記バネ部材は、鋭角状又は円弧状に曲がった形状を有する頂部と、その両側の１対の直線状の傾斜部からなる三角形の側面形状を持ち、かつ、前記頂部にはピンを挿入するためのピン留め孔を備え、
前記１対の傾斜部の一方又は双方に前記留めベースを固定することにより、留めベースの留め部材が前記傾斜部と同一方向へかつ前記ピン留め孔に挿入されたピンの留め部に係合する長さに突出するように構成し、
更に、前記１対の傾斜部の長手方向端部が前記三角形の側面形状の底辺に沿う方向へ曲がった形状の底辺部を有し、これらの底辺部の先端間には一定のスペースが余されており、かつ前記ピン留め孔に挿入されるピンを通過させ得る切欠き部が形成されている留め具である。
第１３発明に係る装飾品の留め具においては、上記の第１２発明と同じ作用・効果が得られる点に加え、次の作用・効果がある。即ち、ピン留め状態にあるピンとピン留めは、バネ部材の頂部のピン留め孔と底辺部との２点において互いに動きを拘束される。そのため、ピン留めがピンに対して揺れ動かないので、ピン留め状態の留め具が不安定に揺れ動かない。An object of the present invention is to provide a pinning type fastener that has a small pin insertion force but a large pin pulling force and that can be easily released from a pinned state by a simple operation.

次に、本願の第１発明〜第１３発明の実施形態を、その最良の実施形態を含めて説明する。以下において単に「本発明」と言う時は、第１発明〜第１３発明を全体的に指している。
〔留め具の全体的な説明〕
本発明に係る留め具は、ピン留めと、先端部付近に留め部を設けたピンとからなるピン留め式の留め具である。そして、ピン留めの留め部材をピンの留め部に係合させることによってピンを留め、この留め部材をピンの留め部から離脱させることによってピン留め状態を解除するものである。
なおピンの留め部は周溝、凹部又は凸部からなる。留め部である周溝は必ずしもピンの全周にわたって設ける必要はない。又、周溝の深さは限定されず、摩擦抵抗も勘案して留め部材の係止力が十分に大きい場合には、周溝が非常に浅く形成され、あるいは、ほとんど周溝が認められない程度であっても良い。留め部である凹部又は凸部の形状は、留め部材を係合させ得る限りにおいて、限定されない。
本発明の留め具は、特に好ましくは、装飾品の留め具に適用される。装飾品以外の比較的小さなサイズの各種の物品、例えばおもちゃ、日用雑貨等についても、その部品同士を、一方にピン留めを他方にピンを設けることにより、互いに留め付けることができる。更に、これらの物品を壁面やボード等に、一方にピン留めを他方にピンを設けることにより、留め付けることにも利用できる。
本発明に係る留め具が用いられる装飾品の種類は、ピン留め式の留め具を備える装飾品である限りにおいて限定されないが、タイタック、ピンブローチ、ピアス、ネックレス等が代表的に例示される。これらの装飾品において、例えば、宝石等をあしらった装飾部材側にピンを取り付け、この装飾部材をピン留め具で留める方式とすることができる。又、他の取り付け方式として、電線や電気コードのジョイントとしても利用できる。ノコギリや柄付きの刃物において、柄の部分と刃物の部分との接続等にも利用できる。
（第１発明〜第１１発明に係るピン留め）
ピン留めには多様な実施形態があるが、前記した第１発明〜第１１発明においては、いずれのピン留めも薄板状バネ材を用いて構成される。
特に好ましくは、薄板状バネ材は、折曲げ加工が可能で、かつ単一の長方形の薄板状バネ材を加工して構成される。この場合には、ピン留めの製造に当たり、平坦で長方形の単一の薄板状バネ材を準備して、例えば打ち抜き加工を施すことによりピン留め孔や留め部材を形成し、次いで、好ましくは加熱処理を伴って必要な折曲げ成形を行う。従って、単一の薄板状バネ材を用いて製造できるため、複数の部品の組み付けが不要であり、しかもピン留めの構造がシンプルであるため、低コストの留め具を提供できる。
上記の薄板状バネ材は、弾性的な変形能力を有する材料からなる。真鍮やステンレス鋼等のバネ鋼はもち論使用できるが、金や白金等の貴金属も一定の弾性的変形能力を有しており、利用できる。硬質プラスチックス製の薄板状バネ材も使用可能である。
薄板状バネ材の厚さは、バネ材の弾性的変形能力の程度や、折り曲げ加工の容易さ等を考慮して適宜に決定される。長方形の薄板状バネ材の寸法は、基本的には製造すべきピン留めの大きさを考慮して決定されるが、同時に、後述の型板部材を成形するために必要な縦横の寸法が必要である。従って、薄板状バネ材に必要とされる縦横の寸法は、ピン留めの実施形態によって異なる場合がある。
薄板状バネ材を加工してピン留めを製造する方法は限定されないが、特に効率的で好ましい方法は、次の第１工程と第２工程からなる。
第１工程として、薄板状バネ材に打ち抜き加工を施して、型板部材（ピン留めを製造するために必要な所定の形状を備えた平坦な薄板状バネ材）を成形する。型板部材は、例えばカッターを用いた加工等の、打ち抜き加工以外の適宜な加工方法によって成形しても良い。
第２工程として、型板部材に対して必要な折り曲げ加工を施し、ピン留めを構成する。第２工程においては、折り曲げ部の形状を固定させるために、加熱処理しながら折り曲げ加工を行うことが好ましい。折り曲げ加工としては、以下の各実施形態に共通する頂部の折り曲げ加工、第１の実施形態におけるストッパの折り曲げ加工、第２、第４及び第５の実施形態における底辺部の折り曲げ加工、第２〜第６の実施形態における耳片の折り曲げ加工、第３及び第４の実施形態における折返し片の折り曲げ加工、第５の実施形態における立上げ部の折り曲げ加工、第６の実施形態におけるピン留め片の折り曲げ加工が含まれる。
（第１２発明及び第１３発明に係るピン留め）
第１２発明及び第１３発明に係るピン留めは、弾性的な変形が可能な材料からなるバネ部材と、留め部材を備える留めベースとによって構成される。
バネ部材の構成材料は、弾性的な変形が可能な材料からなる限りにおいて限定されず、例えば真鍮やステンレス鋼等のバネ鋼の他、一定の弾性的変形能力を有する金や白金等の貴金属も利用できるが、より好ましくは、有機質のバネ材料であるプラスチック材やゴム材（例えばシリコーンゴム材）を利用できる。
バネ部材は、鋭角状又は円弧状に曲がった形状を有する頂部と、その両側の１対の直線状の傾斜部からなる三角形の側面形状を持ち、かつ、前記頂部にはピンを挿入するためのピン留め孔を備える。前記１対の傾斜部の一方又は双方にはピンを留めるための留め部材を備えた留めベースを固定する。留めベースの構成材料は限定されないが、硬質の材料からなることが好ましく、弾性的な変形能は必ずしも要求されない。
バネ部材の傾斜部に留めベースを固定することにより、留めベースに設けた留め部材が、前記傾斜部と同一方向へかつ前記ピン留め孔に挿入されたピンの周溝に喰込む長さに突出するように構成する。
ここにおいて、バネ部材の傾斜部に留めベースを「固定する」とは、留めベースが、少なくともその固定位置よりも傾斜部の先端側へ移動しないようにすることを言う。このような固定手段の内容は限定されないが、例えば、後述の実施形態や実施例において例示するように、留めベースを折曲げ加工が可能な材料を以て構成すると共に、この留めベースに設けた折返し片をバネ部材の傾斜部に巻き付けるようにして折り返したり、その折返し片の端部を傾斜部の先端側に設けた屈曲部に当接させることができる。更に、バネ部材が比較的軟質のプラスチック材やゴム材からなる場合には、折曲げた折返し片をバネ部材の傾斜部に対して食い込ませることもできる。更に、バネ部材の傾斜部と、留めベースとの各一方に、留めベースの固定位置において互いに噛み合って留めベースの傾斜部先端側への移動を制約することとなる適宜な係止手段を構成しても良い。

第４図の（ｃ）に、ピン留め２２を製造するための型板部材２４を示す。この型板部材２４は、折曲げ加工が可能でかつ弾性的な変形能力を有する長方形の薄板状バネ材に対して、打ち抜き加工その他の適宜な加工を施して成形したものである。型板部材２４の中央部２５（破線で囲んだ部分）はピン留め孔を形成する部分である。中央部２５には、一定の形状に切り込み２６を設けることにより、型板部材２４の長手方向に沿って向合う１対の留め部材２７を先端へ向かって次第に幅が細くなる形状に形成している。このような形状の留め部材２７を形成することは設計上の重要な意味を持つが、その点については、実施例２において後述する。
１対の留め部材２７の先端部間には、正確に計算して設計された小さなスペース２８を切り抜いている。言い換えれば、中央部２５にはピン留め孔を形成し、このピン留め孔における長手方向の周縁部から中央部に向けて１対の留め部材２７を突出させ、これらの留め部材２７の先端間にスペース２８を余した形状としている。
このような型板部材２４の中央部２５を、図４（ａ）に示すように円弧状に折り曲げ加工する。その際、加熱処理を行うことにより折り曲げ形状を固定させることが好ましい。但し、１対の留め部材２７は折り曲げない。型板部材２４の長手方向の両端部も破線２９に沿って折り返しても良い。破線２９の部分には、この折り返しを容易にするため、浅い溝状の切込みを入れておいても良い。
こうして形成されたピン留め２２は、単一の長方形の薄板状バネ材からなり、このバネ材の中央部は円弧状に折曲げ成形された頂部３０とされ、頂部３０の両側には１対の傾斜部３１を備える三角形の側面形状を持っている。円弧状に折曲げ成形された頂部３０においては、ピン留め孔における長手方向の周縁部から、１対の留め部材２７を突出させた形状となっている。１対の留め部材２７は、折り曲げ加工されないので、傾斜部と同一方向へ突出している。１対の留め部材２７は、ピン留め孔にピン２３が挿入されたとき、ピンの周溝３２に喰込む長さに突出している。
（実施例１の使用状態）
実施例１に係る留め具２１は、以下のように使用される。即ち、留め具２１をピン留めする際には、ピン留め２２の三角形の形状における底辺側から、頂部３０のピン留め孔に対してピン２３を挿入する。その際、ピン２３は、ピン留め孔に突出した１対の留め部材２７を弾性的に変形させて外側へ押退けながら挿入される。１対の留め部材２７は、傾斜部３１と同一方向へ突出しているため、上記したピンの挿入に対して強い抵抗を示さない。そして、ピン２３の周溝２３ａが留め部材２７の突出位置に到ると、留め部材２７が弾性的に元の形状に戻ってピン２３の周溝２３ａへ進入し、ピン留めが完了する。
留め部材２７がピン２３の周溝２３ａへ進入した際には、軽い打撃音を発するため、ピン留めの完了を容易に確認できる。このため、留め具２１を確実にピン留めすることができる。ピン留め状態にある留め具２１においては、留め部材２７がピン２３の抜ける方向に対する反対方向へ向かって突出した状態で周溝２３ａに食い込んでいるので、そのままの状態では、ピン２３はピン留め具２２から抜けない。このため、ピン留め２２やピン２３が例えば髪の毛や他の部材に引っ掛かったりしてもピン留め状態が維持され、装飾品の脱落による紛失等の不具合が起こらない。
留め具２１のピン留め状態を解除したい場合には、ピン留め２２の１対の傾斜部３１の各端部を、例えば親指と人指し指とで摘んで、第４図の（ｂ）に示す矢印の方向（傾斜部３１の端部間を圧縮する方向）へ力を加える。この操作により、第４図の（ｂ）に示すように、ピン留め２２の頂部３０がより鋭く曲がるように弾性的変形を起こす。
この様子を、第８図によって更に詳しく図示する。第８図の（ａ）はピン留め状態にある頂部３０を示し、第８図の（ｂ）はピン留め状態を解除する際の頂部３０を示す。第８図の（ｂ）に示すように、ピン留め具２２の頂部３０がより鋭く曲がるように弾性的変形を起こすことにより、１対の留め部材２７が互いに開く方向へ変位する。従って、１対の留め部材２７がピン２３の周溝２３ａから離脱する。そのため、ピン留め２２からピン２３が簡単に抜ける。
［実施例２］
（実施例２の製造工程と構成）
本実施例に係る留め具３２は、ピン留め３３と、実施例１の場合と同じピン２３からなる。ピン留め３３は第５図の（ｂ）に示す型板部材３４を用いて製造される。型板部材３４は、折曲げ加工が可能でかつ弾性的な変形能力を有する材料からなる。
この型板部材３４は、前記した型板部材２４と同様に中央部に切り込み２６を設けることにより、１対の留め部材２７とスペース２８を形成している。しかし、型板部材３４においては、長手方向の両端部に、後述する底辺部３７を構成するための延長部分３５を設けている。延長部分３５において、底辺部３７を構成した際に頂部３０の直下となる部分にはピン通孔３６を形成している。ピン通孔３６は図の左右方向に長い長円形に形成されているので、挿入されたピン２３が左右方向へ相対移動することができる。
このような型板部材３４の長手方向の中央部を、第５図の（ａ）に示すように円弧状に折り曲げ加工して、頂部３０と１対の傾斜部３１を形成する。更に、傾斜部３１の端部である延長部分３５を、第５図の（ｂ）の破線に沿って折り曲げ加工することにより、互いに重なる１対の底辺部３７を形成する。これらの破線の部分には、この折り返しを容易にするため、浅い溝状の切込みを入れておいても良い。底辺部３７における頂部３０の直下部には、前記のピン通孔３６が位置している。
又、１対の底辺部３７の先端は、それぞれ、他方の底辺部３７の基部までは到らない長さである。従って、第６図の（ａ）に示すように、留め具３２のピン留め状態を解除する際にピン留め具３３の頂部３０をより鋭く曲がるように弾性的変形させる操作の邪魔にはならない。
第５図の（ｂ）に示すように、延長部分３５の一方の先端には耳片３８が形成されている。上記のように底辺部３７を形成した後、この耳片３８を他方の底辺部３７の方向へ折曲げ成形する。以下の各実施例で図示される耳片についても同様であるが、耳片３８においては、図示する破線に沿って折り返しを容易にするための浅い溝状の切込みを入れておいても良い。上記の耳片３８の折曲げ成形により、双方の底辺部３７を、長手方向への相対的なスライド動作が可能な状態において、互いに拘束させている。
前記の実施例１や後述の各実施例にも共通することであるが、本実施例における１対の留め部材２７は、基端から先端に向かい同じ幅を持つ形状であっても良いが、第５図の（ｂ）に示すように先端へ向かって次第に幅が細くなる形状であることが特に好ましい。
１対の留め部材２７が第５図の（ｂ）に示す形状である場合、型板部材３４における頂部３０に相当する部分（幅Ａで示す部分）が、型板部材３４における留め部材２７の基端部（幅Ｂで示す部分）よりも幅が広くなる。このため、型板部材３４を折曲げ加工してピン留め３３の頂部３０を形成する際、幅Ａで示す部分に折曲げ力が集中しない。従って、第８図の（ｂ）に示すように、幅Ａで示す部分から、その両側の幅Ｂで示す部分に到るまで、全体を均等で緩やかな円弧状に折曲げることができる。このような折曲げ形状を有する頂部３０は、ピン留め３３の三角形の側面形状を弾性的に圧縮変形させるピン留め状態解除操作の繰り返しに対して、優れた耐久性を示す。
１対の留め部材２７が、仮に、基端から先端に向かい同じ幅を持つ形状であった場合、型板部材３４の折曲げ加工において、頂部３０に相当する部分に折曲げ力が集中し、この部分がシャープな円弧状に折曲げられる。このため、第８図の（ｃ）に示すように、１対の留め部材２７の先端間の距離Ｗが、後述する第８図の（ｂ）の場合に比較して、小さくなる。つまり、１対の留め部材２７をピン２３の周溝から離脱させるためには、ピン留め３３をより大きく圧縮変形させることが必要となる。大きな圧縮変形の繰り返しは、頂部３０の弾性的な変形能力の耐久性には悪影響を与える。
（実施例２の使用状態）
実施例２に係る留め具３２の使用状態は、次に述べる点を除いて、実施例１の場合と同様である。即ち、留め具３２のピン留めにおいて、ピン２３は、ピン留め３３の三角形の形状における底辺側から、ピン通孔３６を通過させ、次いで頂部３０のピン留め孔に挿入する。ピン留め状態にあるピン２３とピン留め３３は、頂部３０のピン留め孔と底辺部３７のピン通孔３６との２点において、互いに動きを拘束される。そのため、ピン留め３３がピン２３に対して揺れ動かないので、ピン留め状態の装飾品が不安定に揺れ動かない。
更に、双方の底辺部３７が耳片３８によって互いに拘束されるので、ピン留め３３の構造的な強度が高い。なお、双方の底辺部３７は長手方向への相対的なスライド動作が可能であるため、耳片３８を設けても、実施例１で前記したようなピン留め状態を解除するためのピン留め３３の変形に支障はない。
第７図は、ピン留め状態にある留め具３２の斜視図である。
〔実施例２の変更例〕
実施例２においては、第６図の（ｂ）に示す型板部材３９を用いても良い。この型板部材３９においては、前記した型板部材２４、３４に比較して、１対の留め部材４０が先端へ向かって次第に細くなる形状ではなく、基端から先端まで同じ幅である。
［実施例３］
（実施例３の製造工程と構成）
第１０図の（ａ）及び（ｂ）に示すように、本実施例に係る留め具４１は、ピン留め４２と、実施例１の場合と同じピン２３からなる。ピン留め４２は第９図に示す型板部材４３を用いて製造される。
この型板部材４３は、実施例１に係る型板部材２４と同様に、折曲げ加工が可能で、かつ弾性的な変形能力を有する材料からなる長方形の薄板状バネ材に対して、打ち抜き加工等の適宜な加工を施して成形したものである。型板部材４３の中央部４４には単にピン留め孔４５を形成している。中央部４４の長手方向の両端部には、実施例２に係る型板部材３４と同様の延長部分３５を設け、かつ、これらの延長部分３５にはピン通孔３６を形成している。
一方、中央部４４におけるピン留め孔４５の左右両側の部分からは、短手方向へ折返し片４６を突出させている。更に、これらの折返し片４６からは、中央部４４上に折返された際にピン留め孔４５中へ突出することとなるように、１対の留め部材４７が設けられている。１対の留め部材４７の先端間には、前記型板部材２４の場合のスペース２８と同等のスペース４９が設定されている。又、折返し片４６にはそれぞれ、耳片４８を設けている。
このような型板部材４３の長手方向の中央部を実施例１の場合と同様に円弧状に折り曲げ加工して、頂部３０と１対の傾斜部３１を形成する。更に、傾斜部３１の端部である延長部分３５を、第９図の破線に沿って折り曲げ加工することにより、互いに重なる１対の底辺部３７を形成する。延長部分３５には、図示する破線に沿って、折り返しを容易にするための浅い溝状の切込みを入れておいても良い。底辺部３７における頂部３０の直下部には、前記のピン通孔３６が位置している。１対の底辺部３７の先端は、それぞれ、他方の底辺部３７の基部までは到らない長さである。
更に、前記１対の折返し片４６を、図示する破線に沿って、それぞれ傾斜部３１の表面に重ねるように折曲げ成形する。折返し片４６には、図示する破線に沿って、折り返しを容易にするための浅い溝状の切込みを入れておいても良い。このような折曲げ成形の結果、１対の折返し片４６から突出させた１対の留め部材４７が、ピン留め孔４５の中央部方向へ突出した状態となる。なお、前記した耳片４８を傾斜部３１の方向へ折曲げ成形することにより傾斜部３１に係止させ、この耳片４８によって折返し片４６をそれぞれ傾斜部３１に密着させる。
（実施例３の使用状態）
実施例３に係る留め具４１では、留め部材４７が折返し片４６から突出されている点において構成上の差異はあるが、留め具４１をピン留めする操作やピン留め状態を解除する操作において実施例１の場合と同様である。
又、実施例２の場合と同様、ピン留め状態にあるピン２３とピン留め４２とは、頂部３０のピン留め孔４５と底辺部３７のピン通孔３６との２点において互いに動きを拘束されため、ピン留め状態の装飾品が不安定に揺れ動かない。
〔実施例３の変更例〕
図示はしないが、実施例３の変更例として、実施例２の場合と同様に、底辺部３７の一方に設けた耳片を他方の底辺部３７の方向へ折曲げ成形することにより、双方の底辺部３７を、長手方向への相対的なスライド動作が可能な状態において、互いに拘束させることも好ましい。
［実施例４］
（実施例４の製造工程と構成）
第１１図の（ａ）に示すように、本実施例に係る留め具５０はピン留め５１と、実施例１の場合と同じピン２３からなる。この留め具５０は、例えばネックレスに好ましく適用されるもので、ピン留め５１とピン２３とはそれぞれネックレスの鎖５２に連結されている。
ピン留め５１は第１１図（ｂ）に示す型板部材５３を用いて製造される。型板部材５３は、実施例１に係る型板部材２４と同様に、折曲げ加工が可能で、かつ弾性的な変形能力を有する材料からなる長方形の薄板状バネ材に対して、打ち抜き加工等の適宜な加工を施して成形したものである。型板部材５３の中央部５４には、一定の形状に切り込み２６を設けることにより、中間にスペース２８を余して１対の留め部材２７を形成している。
中央部５４の長手方向の一端部には実施例２に係る型板部材３４と同様の延長部分３５を設け、延長部分３５にはピン通孔３６を形成している。一方、中央部５４の長手方向の他端部には、後述する立上げ部５５を形成するための延長部分５６を設けている。そして、延長部分５６における先端部分には、破線で示す折曲げ予定部５７を介して、短手方向へ１対の耳片５８を突出させている。
このような型板部材５３の長手方向の中央部を実施例１の場合と同様に円弧状に折り曲げ加工して、頂部３０と１対の傾斜部３１を形成する。なお、本実施例においては、頂部３０の折り曲げ角度を鋭角状にして、装飾品の留め具５０を細身に形成している。
そして、前記の延長部分３５を第１１図の（ｂ）の破線に沿って折り曲げ加工することにより、ピン通孔３６を有する底辺部３７を形成する。底辺部３７の先端は、第１１図の（ａ）に示すように、他方の傾斜部３１までは到らない長さである。従って、留め具５０のピン留め状態を解除する際に、ピン留め５１の頂部３０をより鋭く曲がるように弾性的変形させる操作の邪魔にはならない。
一方、もう一つの延長部分５６は、図示する破線に沿って、ピン留め５１の三角形の頂部方向へ折曲げ成形し、立上げ部５５を形成する。延長部分５６には、図示する破線に沿って、折り返しを容易にするための浅い溝状の切込みを入れておいても良い。次いで、この立上げ部５５の先端に設けた前記耳片５８を折曲げ予定部５７で折曲げ、更にその先端の破線部に沿っても折曲げ、ピン留め孔に挿入されたピン２３の先端を囲むシェルター部材５９を筒形に形成している。
（実施例４の使用状態）
実施例４に係る留め具５０においては、実施例２の場合と同様、ピン留め状態にあるピン２３とピン留め５１とは、頂部３０のピン留め孔と底辺部３７のピン通孔３６との２点において互いに動きを拘束されため、ピン留め状態の装飾品が不安定に揺れ動かない。
又、留め具５０が細身に形成されているため、例えばネックレスとして使用した場合に衣類の下に隠れる留め具の膨らみが小さいので、外観や体裁が良い。又、立上げ部５５の存在によって、留め具５０が安定する。更に、ピン留め孔に挿入されたピン２３の先端を囲むシェルター部材５９を形成したので、留め具５０を不注意に扱って、ピンの尖った先端が装着者の指や皮膚に刺さると言う事故を防止することができる。
［実施例５］
（実施例５の製造工程と構成）
本実施例に係る留め具も、ピン留めと、実施例１の場合と同様のピン２３からなる。本実施例に関しては、説明及び図示の重複を避けるために、ピン留めを製造するための型板部材６０又は６１のみを図示して説明する。
第１２図（ａ）、（ｂ）に示すように、第１の型板部材６０も、第２の型板部材６１も、実施例１に係る型板部材２４と同様に、折曲げ加工が可能で、かつ弾性的な変形能力を有する材料からなる長方形の薄板状バネ材に対して、打ち抜き加工等の適宜な加工を施して成形したものである。
第１の型板部材６０において、その中央部６２には単にピン留め孔４５を形成している。中央部６２の長手方向の両端部にはそれぞれ、ピン留め片を形成するための延長部分６３を設け、それぞれの延長部分６３における先端部分には、短手方向へ突出する１対の耳片６４と、長手方向へ突出するやや幅の狭い留め部材６５を設けている。
この型板部材６０から本実施例に係るピン留め具を製造する際には、型板部材６０の長手方向の中央部を実施例１の場合と同様に円弧状に折り曲げ加工して、頂部と１対の傾斜部を形成する。そして延長部分６３を第１２図の（ａ）の破線６３ａに沿って傾斜部の表面側に重ねるように折曲げてピン留め片を形成する。延長部分６３には、この破線に沿って、折り返しを容易にするための浅い溝状の切込みを入れておいても良い。この折曲げ加工により、１対の留め部材６５がピン留め孔４５中へ突出する状態となる。次に、ピン留め片の耳片６４を傾斜部の方向へ折曲げ成形することにより傾斜部に係止させ、この耳片６４によってピン留め片を傾斜部に密着させる。
第２の型板部材６１においては、第１の型板部材６０に比較して１対の耳片６４を備えない点のみが異なる。この型板部材６１から本実施例に係るピン留め具を製造する際には、型板部材６１の長手方向の中央部を折り曲げ加工して頂部と１対の傾斜部を形成した後、延長部分６３を第１２図の（ｂ）の破線に沿って傾斜部の裏面側に重ねるように折曲げ、ピン留め片を形成する。この場合、ピン留め片は傾斜部の裏面側から重ねられているので、耳片等を用いて傾斜部に係止させる必要はない。
［実施例６］
（実施例６の構成）
第１３図〜第１５図に示すように、本実施例に係る留め具は、ピン留め６６と、実施例１の場合と同じピン２３からなる。ピン留め６６は、バネ部材６７と、留めベース６８とによって構成されている。
バネ部材６７は適度な硬さと弾性的変形能力を有するシリコーンゴムの成形品であって、鋭角状又は円弧状に曲がった形状を有する頂部６９と、その両側の１対の直線状の傾斜部７０からなる三角形の側面形状を持ち、かつ、前記頂部にはピン２３を挿入するためのピン留め孔７１を備えている。
前記１対の傾斜部７０の長手方向端部においては、それぞれ、ピン２３の挿入方向とほぼ平行な方向へ屈曲した垂直部７２を介して、前記三角形の側面形状の底辺に沿う方向へ曲がった形状の底辺部７３を形成している。これらの底辺部７３の先端間には一定のスペース７４が余されており、かつピン留め孔７１に挿入されるピン２３を通過させ得る切欠き部７５が形成されている。なお、バネ部材６７における傾斜部７０において、上記の底辺部７３を形成せず、更には底辺部７３及び垂直部７２を形成しない構成とすることも可能である。
前記１対の傾斜部７０には、それぞれ留めベース６８を固定している。但し、留めベース６８は、一方の傾斜部７０のみに１個だけ固定することもできる。留めベース６８は、折曲げ加工が可能な硬質の材料からなる板状の部材であって、図１３（ｂ）に実際の固定位置関係において１対に示すように、ベース部７６と、このベース部から突出した留め部材７７と、留め部材７７に対する直角方向へ突出した１対の折り返し片７８とを備える。
そして、留めベース６８は傾斜部７０に接合させた状態で、この傾斜部７０に巻き付けるように折り返し片７８を折曲げることにより、傾斜部７０に対して固定されている。留めベース６８における傾斜部７０先端側の端部は、前記した垂直部７２に当接しているため、その固定位置よりも傾斜部７０先端側へは移動しない。バネ部材６７に垂直部７２や底辺部７３を形成しない場合には、留めベース６８を固定するために、「実施形態」の欄で前記したような適宜な固定手段が施される。
上記の固定状態において、留めベース６８の留め部材７７は、傾斜部７０と同一方向へ、かつ、ピン留め孔７１に挿入されたピン２３の周溝２３ａに喰込む長さに突出している。
（実施例６の使用状態）
実施例６に係る留め具の使用状態は、基本的に実施例１及び実施例２の場合と同様である。
即ち、留め具をピン留めする際には、ピン留め６６におけるバネ部材６７の三角形の形状の底辺側から、頂部６９のピン留め孔７１に対してピン２３を挿入する。その際ピン２３は、ピン留め孔７１に突出した留め部材７７を外側へ押退けながら挿入される。１対の留め部材７７は、傾斜部７０と同一方向へ突出しているため、上記したピン２３の挿入に対して強い抵抗を示さない。そして、ピン２３の周溝２３ａが留め部材７７の突出位置に到ると、留め部材７７が元の位置戻ってピン２３の周溝２３ａへ進入し、ピン留めが完了する。
留め部材７７がピン２３の周溝２３ａへ進入した際には、軽い打撃音を発するため、ピン留めの完了を容易に確認できる。このため、留め具を確実にピン留めすることができる。ピン留め状態にある留め具においては留め部材７７がピン２３の抜ける方向に対する反対方向へ向かって突出した状態で周溝２３ａに食い込んでいるので、そのままの状態では、ピン２３はピン留め６６から抜けない。このため、ピン留め６６やピン２３が例えば髪の毛や他の部材に引っ掛かったりしても、ピン留め状態が維持され、装飾品の脱落による紛失等の不具合が起こらない。
留め具のピン留め状態を解除したい場合には、バネ部材６７の１対の傾斜部７０の各端部を、例えば親指と人指し指とで摘んで、傾斜部７０の端部間を圧縮する方向へ力を加える。この操作により、第１４図の（ｂ）に示すように、バネ部材６７の頂部６９が、より鋭く曲がるように弾性的変形を起こす。１対の底辺部７３の先端間に余したスペース７４が、この弾性的変形を許容する。この弾性的変形によって、第１４図の（ｂ）に示すようにスペース７４が無くなった時、ピン２３は、１対の切欠き部７５によって形成される孔を通過している状態となる。このようなバネ部材６７の弾性的変形により、１対の留め部材７７が互いに開く方向へ変位する。従って、１対の留め部材７７がピン２３の周溝２３ａから離脱する。そのため、ピン留め６６からピン２３が簡単に抜ける。
又、留め具のピン留めにおいて、ピン２３は、バネ部材６７の三角形の形状における底辺側からスペース７４を通過させ、次いで頂部６９のピン留め孔７１に挿入する。ピン留め状態にあるピン２３とピン留め６６は、頂部６９のピン留め孔７１と底辺部７３との２点において、互いに動きを拘束される。そのため、ピン留め６６がピン２３に対して揺れ動かないので、ピン留め状態の装飾品が不安定に揺れ動かない。
［実施例７］
（実施例７の製造工程と構成）
第１７図に示すように、本実施例に係る留め具７９は、ピン留め８０と、実施例１の場合と同じピン２３からなる。ピン留め８０は第１６図に示す型板部材８１を用いて製造される。
型板部材８１は、折曲げ加工が可能で弾性的な変形能力を有する長方形の薄板状バネ材に打ち抜き加工を施して成形したものである。型板部材８１の中央部には、一定の形状に切り込み８２を設けることにより、先端部間に小さなスペースを残して１対の留め部材８３を形成している。この実施例では、切り込み８２を図示のようにカーブ状に設けることにより、１対の留め部材８３が先端へ向かってカーブを伴って次第に細くなる形状とされている。そのため、型板部材８１を折曲げ加工してピン留め８０の頂部を形成する際、とりわけ緩やかな円弧状に折曲げることができる。
型板部材８１の長手方向の両端部には、２ケ所の折曲げ予定線８５、８６の先端側に、ストッパ８７（第１７図参照）となるべき延長部分８８を設けている。又、２ケ所の折曲げ予定線８５、８６に挟まれた部分には、小さな四角形の起立片８９（第１７図参照）を形成するための各１対の切り込み９０を形成している。
このような型板部材８１の長手方向の中央部を実施例１の場合と同様に円弧状に折曲げ加工して、第１７図及び第１８図に示すように、頂部８４と１対の傾斜部９１を形成する。更に、傾斜部９１の端部を折曲げ予定線８５、８６に沿って第１８図に示すように折曲げ加工することにより、底辺方向へ一定の長さで突出するストッパ８７を形成し、更に、底辺方向に対する直角方向へ起立片８９を折曲げ加工する。
（実施例７の使用状態）
実施例７に係る留め具７９の使用状態は、留め具７９をピン留めする操作や、ピン留め状態を解除する操作において実施例１の場合と基本的に同様である。但し、ピン留め８０を第１９図のように弾性的に圧縮変形させる際、手の指を起立片８９に当てて操作できるので、ピン留め状態を解除する操作が容易である。又、その操作は、ストッパ８７がピン２３に当たることによって規制されるためめ、ピン留め８０を過剰に圧縮変形させる恐れがない。
［実施例８］
第２１図に示すように、本実施例に係る留め具９２は、ピン留め９３と、実施例１の場合と同じピン２３からなる。ピン留め９３は第２０図に示す型板部材９４を用いて製造される。
本実施例においては、上記実施例７のストッパ８７に相当するストッパ９５の先端部に、１対のアーム片９６を形成している。ピン留め９３を構成する際は、第２１図に示すように、双方のストッパ９５における１対のアーム片９６を互いに上下にクロスして重なるように組み付ける。その結果、双方のアーム片９６が互いに拘束されるために、ピン留め９３の構造的安定性が向上する。更には、双方のアーム片９６がピン２３を通過させるピン通孔を形成する。本実施例における上記以外の点は、実施例７と同様である。

[Example 1]
(Manufacturing process and configuration of Example 1)
The fastener 21 includes a pin fastener 22 and a pin 23.
FIG. 4C shows a template member 24 for manufacturing the pinning 22. The template member 24 is formed by subjecting a rectangular thin plate-shaped spring material that can be bent and has elastic deformation capability to punching or other appropriate processing. A central portion 25 (portion surrounded by a broken line) of the template member 24 is a portion for forming a pinning hole. In the central portion 25, a pair of fastening members 27 facing along the longitudinal direction of the template member 24 are formed in a shape that gradually becomes narrower toward the tip by providing cuts 26 in a fixed shape. Yes. The formation of the fastening member 27 having such a shape is important in terms of design. This point will be described later in the second embodiment.
A small space 28 is cut out between the tip portions of the pair of fastening members 27 and is calculated and calculated accurately. In other words, a pinning hole is formed in the central portion 25, and a pair of fastening members 27 protrude from the peripheral edge in the longitudinal direction of the pinning hole toward the central portion, and between the tips of these fastening members 27. The space 28 has a surplus shape.
The central portion 25 of the template member 24 is bent into an arc shape as shown in FIG. At that time, it is preferable to fix the bent shape by performing a heat treatment. However, the pair of fastening members 27 are not bent. Both ends in the longitudinal direction of the template member 24 may be folded along the broken line 29. A shallow groove-shaped cut may be formed in the portion of the broken line 29 in order to facilitate this folding.
The pinning 22 formed in this way consists of a single rectangular thin plate spring material, and the central portion of the spring material is a top portion 30 formed by bending in a circular arc shape, and a pair of both sides of the top portion 30 is formed. It has a triangular side surface shape including the inclined portion 31. The top portion 30 bent in an arc shape has a shape in which a pair of fastening members 27 protrude from the peripheral edge portion in the longitudinal direction of the pin fastening hole. Since the pair of fastening members 27 are not bent, they protrude in the same direction as the inclined portion. The pair of fastening members 27 protrude to a length that bites into the peripheral groove 32 of the pin when the pin 23 is inserted into the pin fastening hole.
(Use state of Example 1)
The fastener 21 according to the first embodiment is used as follows. That is, when pinning the fastener 21, the pin 23 is inserted into the pinning hole of the top 30 from the bottom side in the triangular shape of the pinning 22. At that time, the pin 23 is inserted while elastically deforming the pair of fastening members 27 protruding into the pin fastening holes and pushing them outward. Since the pair of fastening members 27 protrude in the same direction as the inclined portion 31, the pair of fastening members 27 does not exhibit strong resistance to the above-described pin insertion. Then, when the circumferential groove 23a of the pin 23 reaches the protruding position of the retaining member 27, the retaining member 27 elastically returns to its original shape and enters the circumferential groove 23a of the pin 23, and the pinning is completed.
When the fastening member 27 enters the circumferential groove 23a of the pin 23, a light impact sound is emitted, so that the completion of the pinning can be easily confirmed. For this reason, the fastener 21 can be pinned reliably. In the fastener 21 in the pinned state, since the fastening member 27 bites into the circumferential groove 23a in a state of projecting in the direction opposite to the direction in which the pin 23 is pulled out, the pin 23 is the pin fastener in the state as it is. Can't escape from 22. For this reason, even if the pinning 22 or the pin 23 is caught by, for example, hair or other members, the pinning state is maintained, and problems such as loss due to dropout of the decorative article do not occur.
When it is desired to release the pinned state of the fastener 21, the end portions of the pair of inclined portions 31 of the pin fastener 22 are picked with, for example, the thumb and the index finger, and the arrow shown in FIG. A force is applied in the direction (the direction in which the space between the end portions of the inclined portion 31 is compressed). By this operation, as shown in FIG. 4B, elastic deformation is caused so that the top 30 of the pinning 22 bends more sharply.
This is illustrated in more detail in FIG. FIG. 8A shows the top 30 in the pinned state, and FIG. 8B shows the top 30 when the pinned state is released. As shown in FIG. 8 (b), by causing elastic deformation so that the top 30 of the pin fastener 22 bends more sharply, the pair of fastening members 27 are displaced in the direction of opening each other. Accordingly, the pair of fastening members 27 is detached from the circumferential groove 23 a of the pin 23. Therefore, the pin 23 can be easily removed from the pin clamp 22.
[Example 2]
(Production process and configuration of Example 2)
The fastener 32 according to the present embodiment includes a pin clamp 33 and the same pin 23 as in the first embodiment. The pinning 33 is manufactured by using a template member 34 shown in FIG. The template member 34 is made of a material that can be bent and has elastic deformation ability.
The template member 34 forms a pair of fastening members 27 and a space 28 by providing a notch 26 at the center as in the template member 24 described above. However, the template member 34 is provided with extended portions 35 for constituting a bottom portion 37 to be described later at both ends in the longitudinal direction. In the extended portion 35, a pin through hole 36 is formed in a portion directly below the top portion 30 when the bottom side portion 37 is formed. Since the pin through hole 36 is formed in an oval shape that is long in the left-right direction in the figure, the inserted pin 23 can relatively move in the left-right direction.
The central portion of the template member 34 in the longitudinal direction is bent into an arc shape as shown in FIG. 5A to form a pair of inclined portions 31 with the top portion 30. Further, the extended portion 35 that is the end portion of the inclined portion 31 is bent along the broken line in FIG. 5B to form a pair of base portions 37 that overlap each other. These broken line portions may be provided with shallow groove-shaped cuts in order to facilitate the folding. The pin through hole 36 is located immediately below the top 30 in the bottom 37.
Further, the tip ends of the pair of bottom side portions 37 each have a length that does not reach the base portion of the other bottom side portion 37. Therefore, as shown in FIG. 6 (a), when the pin 32 is released from the pinned state, it does not interfere with the operation of elastically deforming the top 30 of the pin clasp 33 so as to bend more sharply.
As shown in FIG. 5B, an ear piece 38 is formed at one end of the extended portion 35. After the bottom portion 37 is formed as described above, the ear piece 38 is bent in the direction of the other bottom portion 37. The same applies to the ear pieces illustrated in the following embodiments, but the ear pieces 38 may be provided with shallow groove-shaped cuts for facilitating folding along the illustrated broken lines. By bending the above-mentioned ear piece 38, both bottom sides 37 are restrained to each other in a state in which a relative sliding operation in the longitudinal direction is possible.
Although this is common to the first embodiment and each of the embodiments described later, the pair of fastening members 27 in the present embodiment may have a shape having the same width from the proximal end to the distal end. As shown in FIG. 5 (b), it is particularly preferable that the width gradually decreases toward the tip.
When the pair of fastening members 27 has the shape shown in FIG. 5B, the portion corresponding to the top 30 in the template member 34 (the portion indicated by the width A) is the portion of the fastening member 27 in the template member 34. The width is wider than the base end portion (the portion indicated by the width B). For this reason, when the template member 34 is bent to form the top portion 30 of the pinning 33, the bending force is not concentrated on the portion indicated by the width A. Therefore, as shown in FIG. 8 (b), the whole can be bent into a uniform and gentle arc from the portion indicated by the width A to the portion indicated by the width B on both sides thereof. The top portion 30 having such a bent shape exhibits excellent durability against repeated pinning state releasing operations that elastically compressively deform the triangular side surface shape of the pinning 33.
If the pair of fastening members 27 have a shape having the same width from the proximal end to the distal end, the bending force concentrates on the portion corresponding to the top 30 in the bending process of the template member 34, This part is bent into a sharp arc shape. For this reason, as shown in FIG. 8 (c), the distance W between the tips of the pair of fastening members 27 is smaller than in the case of FIG. 8 (b) described later. That is, in order to disengage the pair of fastening members 27 from the circumferential groove of the pin 23, it is necessary to further compress and deform the pin fastening 33. Repeated large compression deformation adversely affects the durability of the elastic deformation capability of the top 30.
(Use state of Example 2)
The usage state of the fastener 32 according to the second embodiment is the same as that of the first embodiment except for the points described below. That is, in the pinning of the fastener 32, the pin 23 passes from the bottom side in the triangular shape of the pinning 33 through the pin through hole 36 and then inserted into the pinning hole of the top 30. The pin 23 and the pin clamp 33 in the pinned state are restrained from moving at two points: a pin clamp hole at the top portion 30 and a pin through hole 36 at the bottom portion 37. Therefore, since the pin clamp 33 does not swing with respect to the pin 23, the pinned ornament does not swing unstable.
Further, since both bottom sides 37 are restrained by the ear pieces 38, the structural strength of the pinning 33 is high. In addition, since both the base parts 37 can be relatively slid in the longitudinal direction, even if the ear piece 38 is provided, the pinning 33 for releasing the pinning state as described in the first embodiment is used. There is no hindrance to deformation.
FIG. 7 is a perspective view of the fastener 32 in a pinned state.
[Modification of Example 2]
In the second embodiment, a template member 39 shown in FIG. 6B may be used. In this template member 39, compared to the above-described template members 24 and 34, the pair of fastening members 40 are not shaped to be gradually narrowed toward the distal end, but have the same width from the proximal end to the distal end.
[Example 3]
(Manufacturing process and configuration of Example 3)
As shown in FIGS. 10 (a) and 10 (b), the fastener 41 according to this embodiment includes a pin 42 and the same pin 23 as in the first embodiment. The pinning 42 is manufactured using a template member 43 shown in FIG.
Like the template member 24 according to the first embodiment, the template member 43 is punched against a rectangular thin plate-shaped spring material that can be bent and has elastic deformation ability. It is formed by performing appropriate processing such as. A pin hole 45 is simply formed in the central portion 44 of the template member 43. Extension portions 35 similar to the template member 34 according to the second embodiment are provided at both ends in the longitudinal direction of the central portion 44, and pin through holes 36 are formed in these extension portions 35.
On the other hand, the folded piece 46 protrudes from the left and right sides of the pinning hole 45 in the central portion 44 in the short direction. Further, a pair of fastening members 47 are provided from these folded pieces 46 so as to protrude into the pinning holes 45 when folded back on the central portion 44. A space 49 equivalent to the space 28 in the case of the template member 24 is set between the tips of the pair of fastening members 47. Each folded piece 46 is provided with an ear piece 48.
The central portion of the template member 43 in the longitudinal direction is bent into an arc shape in the same manner as in the first embodiment, so that the top portion 30 and a pair of inclined portions 31 are formed. Further, the extended portion 35 which is the end portion of the inclined portion 31 is bent along the broken line in FIG. 9 to form a pair of base portions 37 that overlap each other. The extended portion 35 may be provided with a shallow groove-shaped cut for facilitating folding along the broken line shown in the figure. The pin through hole 36 is located immediately below the top 30 in the bottom 37. The front ends of the pair of bottom side portions 37 have a length that does not reach the base portion of the other bottom side portion 37.
Further, the pair of folded pieces 46 are bent and formed so as to overlap the surface of the inclined portion 31 along the broken line shown in the figure. The folded piece 46 may be provided with a shallow groove-shaped notch for facilitating folding along the broken line shown in the figure. As a result of such folding forming, the pair of fastening members 47 projecting from the pair of folded pieces 46 project to the center portion of the pinning hole 45. Note that the above-described ear piece 48 is bent in the direction of the inclined portion 31 to be locked to the inclined portion 31, and the folded piece 46 is brought into close contact with the inclined portion 31 by the ear piece 48.
(Use state of Example 3)
In the fastener 41 according to the third embodiment, there is a structural difference in that the fastening member 47 protrudes from the folded piece 46, but the operation is performed in the operation of pinning the fastener 41 and the operation of releasing the pinned state. The same as in the case of Example 1.
As in the second embodiment, the pin 23 and the pin clamp 42 in the pinned state are restrained from moving at two points, that is, the pin clamp hole 45 in the top portion 30 and the pin through hole 36 in the bottom portion 37. For this reason, the pinned ornaments do not swing unstably.
[Modification of Example 3]
Although not shown in the figure, as a modification of the third embodiment, as in the second embodiment, both of the ear pieces provided on one of the bottom portions 37 are bent in the direction of the other bottom portion 37, so that both It is also preferable that the bases 37 are constrained to each other in a state in which a relative sliding operation in the longitudinal direction is possible.
[Example 4]
(Manufacturing process and configuration of Example 4)
As shown in FIG. 11 (a), the fastener 50 according to this embodiment includes a pin 51 and the same pin 23 as in the first embodiment. The fastener 50 is preferably applied to, for example, a necklace, and the pin clamp 51 and the pin 23 are connected to a chain 52 of the necklace, respectively.
The pinning 51 is manufactured using a template member 53 shown in FIG. As with the template member 24 according to the first embodiment, the template member 53 can be bent and is punched into a rectangular thin plate-shaped spring material made of a material having elastic deformation ability. These are formed by performing appropriate processing. In the central portion 54 of the template member 53, a pair of fastening members 27 are formed with a space 28 in the middle by providing a cut 26 in a fixed shape.
An extension portion 35 similar to the template member 34 according to the second embodiment is provided at one end portion in the longitudinal direction of the central portion 54, and a pin through hole 36 is formed in the extension portion 35. On the other hand, an extension portion 56 for forming a rising portion 55 described later is provided at the other end portion in the longitudinal direction of the central portion 54. A pair of ear pieces 58 project from the distal end portion of the extended portion 56 in a short direction via a planned bending portion 57 indicated by a broken line.
The central portion in the longitudinal direction of the template member 53 is bent into an arc shape in the same manner as in the first embodiment, so that the top portion 30 and a pair of inclined portions 31 are formed. In the present embodiment, the top 30 is bent at an acute angle, and the decorative fastener 50 is formed thin.
Then, the extended portion 35 is bent along the broken line in FIG. 11B to form a bottom portion 37 having a pin through hole 36. The tip of the bottom 37 has a length that does not reach the other inclined portion 31 as shown in FIG. Therefore, when releasing the pinned state of the fastener 50, the operation of elastically deforming the top 30 of the pinned 51 so as to bend more sharply is not disturbed.
On the other hand, the other extended portion 56 is bent and formed in the direction of the apex of the triangle of the pinning 51 along the broken line shown in the drawing to form the rising portion 55. The extended portion 56 may be provided with a shallow groove-shaped cut for facilitating folding along the broken line shown in the drawing. Next, the ear piece 58 provided at the tip of the rising portion 55 is bent at the planned bending portion 57 and further bent along the broken line portion at the tip, and the tip of the pin 23 inserted into the pin retaining hole. A shelter member 59 is formed in a cylindrical shape.
(Use state of Example 4)
In the fastener 50 according to the fourth embodiment, as in the second embodiment, the pin 23 and the pinned 51 in the pinned state are formed by the pinned hole of the top portion 30 and the pin through hole 36 of the bottom portion 37. Since the movement is restrained at two points, the pinned ornament does not swing unstably.
Moreover, since the fastener 50 is formed in a thin shape, for example, when used as a necklace, since the swelling of the fastener hidden under the clothing is small, the appearance and appearance are good. Further, the presence of the rising portion 55 stabilizes the fastener 50. Further, since the shelter member 59 surrounding the tip of the pin 23 inserted into the pin fastening hole is formed, the fastener 50 is carelessly handled and the pointed tip of the pin is stuck in the finger or skin of the wearer. Can be prevented.
[Example 5]
(Manufacturing process and configuration of Example 5)
The fastener according to the present embodiment also includes pinning and the same pin 23 as in the first embodiment. In order to avoid duplication of description and illustration, only the template member 60 or 61 for manufacturing the pinning will be illustrated and described with respect to the present embodiment.
As shown in FIGS. 12 (a) and 12 (b), both the first template member 60 and the second template member 61 are bent as in the template member 24 according to the first embodiment. A rectangular thin plate-shaped spring material made of a material that is capable of elastic deformation is formed by performing an appropriate process such as a punching process.
In the first template member 60, a pinning hole 45 is simply formed in the central portion 62. Extension portions 63 for forming pinning pieces are provided at both ends in the longitudinal direction of the central portion 62, and a pair of ear pieces 64 projecting in the short direction are provided at the tip portions of the respective extension portions 63. And a slightly narrow fastening member 65 protruding in the longitudinal direction.
When manufacturing the pin fastener according to the present embodiment from the template member 60, the center portion in the longitudinal direction of the template member 60 is bent into an arc shape in the same manner as in the first embodiment, A pair of inclined portions is formed. And the extension part 63 is bent so that it may overlap with the surface side of an inclined part along the broken line 63a of Fig.12 (a), and a pinning piece is formed. The extended portion 63 may be provided with a shallow groove-like cut for easy folding along the broken line. By this bending process, the pair of fastening members 65 project into the pin fastening holes 45. Next, the ear piece 64 of the pinning piece is bent and formed in the direction of the inclined part to be locked to the inclined part. The pin piece is brought into close contact with the inclined part by the ear piece 64.
The second template member 61 is different from the first template member 60 only in that the pair of ear pieces 64 is not provided. When the pin fastener according to the present embodiment is manufactured from the template member 61, the center portion in the longitudinal direction of the template member 61 is bent to form a pair of inclined portions with the top portion, and then the extended portion. 63 is bent along the broken line in FIG. 12 (b) so as to overlap the back side of the inclined portion to form a pinning piece. In this case, since the pinning piece is overlapped from the back side of the inclined portion, it is not necessary to use the ear piece or the like to be locked to the inclined portion.
[Example 6]
(Configuration of Example 6)
As shown in FIGS. 13 to 15, the fastener according to the present embodiment includes a pin clamp 66 and the same pin 23 as in the first embodiment. The pin clamp 66 includes a spring member 67 and a clamp base 68.
The spring member 67 is a molded product of silicone rubber having an appropriate hardness and elastic deformation capability, and has a top portion 69 having a sharp or arcuate shape and a pair of linear inclined portions 70 on both sides thereof. The pin has a triangular side shape and a pin retaining hole 71 for inserting the pin 23 at the top.
The longitudinal ends of the pair of inclined portions 70 are bent in a direction along the bottom of the triangular side surface shape through vertical portions 72 bent in a direction substantially parallel to the insertion direction of the pin 23. A bottom portion 73 having a shape is formed. A fixed space 74 is left between the tips of these bottom side portions 73, and a notch portion 75 through which the pin 23 inserted into the pinning hole 71 can pass is formed. In addition, in the inclined part 70 in the spring member 67, it is also possible to adopt a configuration in which the base part 73 is not formed, and further, the base part 73 and the vertical part 72 are not formed.
A fastening base 68 is fixed to each of the pair of inclined portions 70. However, only one fastening base 68 can be fixed to only one inclined portion 70. The fastening base 68 is a plate-like member made of a hard material that can be bent. As shown in FIG. 13B as a pair in the actual fixed positional relationship, the base portion 76 and this base And a pair of folded pieces 78 projecting in a direction perpendicular to the fastening member 77.
The fastening base 68 is fixed to the inclined portion 70 by bending the folded piece 78 so as to be wound around the inclined portion 70 in a state of being joined to the inclined portion 70. Since the end portion on the distal end side of the inclined portion 70 in the fastening base 68 is in contact with the vertical portion 72 described above, it does not move to the distal end side of the inclined portion 70 from its fixed position. When the vertical part 72 and the bottom part 73 are not formed on the spring member 67, in order to fix the fastening base 68, an appropriate fixing means as described above in the “embodiment” column is applied.
In the above-described fixed state, the fastening member 77 of the fastening base 68 protrudes in the same direction as the inclined portion 70 and has a length so as to bite into the circumferential groove 23 a of the pin 23 inserted into the pin fastening hole 71.
(Use state of Example 6)
The usage state of the fastener according to the sixth embodiment is basically the same as that of the first and second embodiments.
That is, when pinning the fastener, the pin 23 is inserted into the pinning hole 71 of the top 69 from the bottom side of the triangular shape of the spring member 67 in the pinning 66. At that time, the pin 23 is inserted while pushing the retaining member 77 protruding into the pin retaining hole 71 outward. Since the pair of fastening members 77 protrude in the same direction as the inclined portion 70, the pair of fastening members 77 does not exhibit strong resistance to the insertion of the pin 23 described above. When the circumferential groove 23a of the pin 23 reaches the protruding position of the retaining member 77, the retaining member 77 returns to the original position and enters the circumferential groove 23a of the pin 23, and the pinning is completed.
When the fastening member 77 enters the circumferential groove 23a of the pin 23, a light impact sound is emitted, so that the completion of the pinning can be easily confirmed. For this reason, a fastener can be pinned reliably. In the fastener in the pinned state, since the fastening member 77 bites into the circumferential groove 23a in a state of protruding in the direction opposite to the direction in which the pin 23 is removed, the pin 23 is removed from the pinned pin 66 in the state as it is. Absent. For this reason, even if the pinning 66 or the pin 23 is caught by, for example, hair or other members, the pinning state is maintained, and problems such as loss due to falling off of the ornament do not occur.
When it is desired to release the pinned state of the fastener, the ends of the pair of inclined portions 70 of the spring member 67 are gripped by, for example, the thumb and the index finger, and the space between the ends of the inclined portion 70 is compressed. Apply power. By this operation, as shown in FIG. 14B, the top portion 69 of the spring member 67 is elastically deformed so as to bend more sharply. The space 74 left between the tips of the pair of bottom side portions 73 allows this elastic deformation. Due to this elastic deformation, when the space 74 disappears as shown in FIG. 14 (b), the pin 23 passes through the hole formed by the pair of notches 75. Due to such elastic deformation of the spring member 67, the pair of fastening members 77 are displaced in a direction to open each other. Accordingly, the pair of fastening members 77 is detached from the circumferential groove 23 a of the pin 23. Therefore, the pin 23 can be easily removed from the pin clamp 66.
Further, in pinning the fastener, the pin 23 passes through the space 74 from the bottom side in the triangular shape of the spring member 67 and then is inserted into the pinning hole 71 of the top portion 69. The pin 23 and the pin clamp 66 in the pinned state are restrained from moving at two points, that is, the pin clamp hole 71 and the base 73 of the top 69. Therefore, the pinning 66 does not swing with respect to the pin 23, so that the pinned ornament does not swing unstably.
[Example 7]
(Manufacturing process and configuration of Example 7)
As shown in FIG. 17, the fastener 79 according to this embodiment includes a pin fastener 80 and the same pin 23 as in the first embodiment. The pinning 80 is manufactured using a template member 81 shown in FIG.
The template member 81 is formed by punching a rectangular thin plate spring material that can be bent and has an elastic deformation capability. A pair of fastening members 83 are formed in the central portion of the template member 81 by providing a notch 82 in a fixed shape, leaving a small space between the tip portions. In this embodiment, the notches 82 are provided in a curved shape as shown in the figure, so that the pair of fastening members 83 are gradually narrowed with a curve toward the tip. Therefore, when the template member 81 is bent to form the top portion of the pinning 80, it can be bent in a particularly gentle arc shape.
