Description

装身具の挟着構造Tightening structure for jewelry
この発明はイヤリングや指輪、ブレスレット等に適用される装身具の挟着構造に関するものである。 The present invention relates to a sandwiching structure for jewelry applied to earrings, rings, bracelets and the like.
本発明者は、従来から新規な装身具の挟着構造を提案してきた。
先ず第1に、特開平１０－２７６８１０号公報（特許文献１参照）において、図７に示すように一対の取付脚部２２，２３を備えた主装飾体２１と、一対の取付脚部２２，２３間に納まる取付基部２５が形成された挟着部材２４とを備え、取付脚部２２，２３と取付基部２５との間にワッシャ２６を介在させた上、これらをピン２７によって貫通させ、かつ当該部位を加締めることによって両者を閉じた際に挟着力を付与するイヤリングを提案した。 The inventor of the present invention has conventionally proposed a novel sandwiching structure for jewelry.
First, in Japanese Patent Laid-Open No. 10-276810 (see Patent Document 1), as shown in FIG. 7, a main decorative body 21 having a pair of mounting legs 22, 23, and a pair of mounting legs 22, 23, a sandwiching member 24 having a mounting base 25 formed between the mounting legs 25, 23, and a washer 26 interposed between the mounting legs 22, 23 and the mounting base 25, and these pins are penetrated by pins 27, and We proposed an earring that gives pinching force when both parts are closed by caulking the part.
上述のワッシャ状の板材を介在させたイヤリングにおいては、耳たぶに対しては両者の摩擦によってそれ程大きな挟着力を発揮せずに装着することができ、またこの両者の開閉を繰り返すことによって接触し合う取付脚部と取付基部とが接触摩擦により摩耗したり変形することもある程度防ぐことができるものの、使用中に挟着力が低下しやすいという問題はいまだ残されたままである。 In the above-mentioned earring with a washer-like plate interposed, it can be attached to the earlobe without exerting such a large clamping force due to friction between the two, and contact with each other by repeatedly opening and closing the both. Although it is possible to prevent the mounting leg and the mounting base from being worn or deformed by contact friction to some extent, the problem that the clamping force tends to decrease during use still remains.
そこで本発明者は、実用新案登録第３１３０９９３号公報（特許文献２）において、図８に示すように一方の主装飾体３１と他方の挟着部材３４とに一対の取付脚部３２，３３と取付基部３５とを形成するとともに、前記一対の取付脚部３２，３３と取付基部３５との間に少なくとも２枚以上の平滑な金属板材３６を介装してこれらをピン３７によって軸着するとともに、前記金属板材３６とともに該軸部を加締めてなるイヤリングであって、前記取付基部３５の板面には前記金属板材３６よりも大きい面積の凹部３８が形成されているイヤリングを提案した。 Therefore, the present inventor, in Utility Model Registration No. 3130993 (Patent Document 2), as shown in FIG. 8, a pair of mounting legs 32 and 33 are attached to one main decorative body 31 and the other sandwiching member 34. The mounting base 35 is formed, and at least two or more smooth metal plate members 36 are interposed between the pair of mounting legs 32 and 33 and the mounting base 35, and these are pivotally attached by pins 37. The earring is formed by caulking the shaft portion together with the metal plate material 36, and an earring in which a recess 38 having a larger area than the metal plate material 36 is formed on the plate surface of the mounting base 35.
また、前記一対の取付脚部３２，３３と取付基部３５との間に介在させる平滑な金属板材３６が１枚であってもよいことを見出し、実用新案登録第３１３９６５９号公報（特許文献３）も提案している。 Further, it has been found that there may be one smooth metal plate 36 interposed between the pair of mounting legs 32, 33 and the mounting base 35, and utility model registration No. 3139659 (Patent Document 3). Has also proposed.
さらに、前記取付基部を前記金属板材の面積よりも細い幅に形成し、一方の主装飾体と他方の挟着部材とにそれぞれ形成された取付脚部と取付基部とが相対的に回動する際、前記金属板材にかかる負荷が前記取付基部の幅方向の端縁との係合部分にかかるようにしたイヤリングを特開２０１１－０７８４６０号公報（特許文献４）において提案している。 Further, the mounting base is formed with a width narrower than the area of the metal plate, and the mounting leg and the mounting base formed on one main decorative body and the other sandwiching member respectively rotate relatively. In this regard, Japanese Patent Laid-Open No. 2011-078460 (Patent Document 4) proposes an earring in which a load applied to the metal plate material is applied to an engagement portion with an end edge in the width direction of the mounting base.

上述のように、実用新案登録第３１３０９９３号公報（特許文献２）および実用新案登録第３１３９６５９号公報（特許文献３）、特開２０１１－０７８４６０号公報（特許文献４）においては、前記一対の取付脚部と取付基部との間に１枚もしくは２枚以上の平滑な金属板材を介装してこれらを軸着するとともに、前記金属板材とともに該軸部を加締めてなるイヤリングが提案されている。
しかしながら、平滑な金属板材を１枚以上とすることによって挟着力が極めて長期間にわたって保持されるというメリットはあるものの、この種の製品の弱点であった挟着力の持続に関する問題点を根本的に解消することができないという問題があった。 As described above, in the utility model registration No. 3130993 (Patent Document 2), the utility model registration No. 3139659 (Patent Document 3), and Japanese Patent Application Laid-Open No. 2011-078460 (Patent Document 4), the pair of attachments Earrings have been proposed in which one or two or more smooth metal plate members are interposed between a leg portion and an attachment base portion, and these are pivotally attached, and the shaft portion is crimped together with the metal plate material. .
However, although there is a merit that the clamping force can be maintained for a very long time by using one or more smooth metal plate materials, the fundamental problem with respect to the persistence of the clamping force, which was a weak point of this type of product, is There was a problem that it could not be resolved.
この発明は従来の装身具の挟着構造の前記欠点を改良するものであって、一対の取付脚部と取付基部との間に３枚以上の平滑な金属板材を介装し、前記一対の取付脚部の輪郭内に収容される面積のものを使用するとともに、一対の取付脚部と取付基部に接する両端の金属板材をそれぞれ取付脚部と取付基部に強固に結合させ、一方の主装飾体と他方の挟着部材とにそれぞれ形成された取付脚部と取付基部とが相対的に回動する際、前記３枚以上の各金属板材の係合面に負荷がかかって充分な挟着力が得られるとともに、長い期間の使用に耐えられる装身具の挟着構造を提供しようとするものである。 The present invention is to improve the above-mentioned drawback of the conventional accessory sandwiching structure, wherein three or more smooth metal plate members are interposed between a pair of mounting legs and a mounting base, and the pair of mountings One of the main decorative bodies is one having an area accommodated in the contour of the leg, and firmly joining the pair of mounting legs and the metal plate at both ends contacting the mounting base to the mounting leg and the mounting base, respectively. When the mounting leg portion and the mounting base portion formed on each of the other clamping members relatively rotate, a load is applied to the engagement surfaces of the three or more metal plate members so that a sufficient clamping force is obtained. It is an object of the present invention to provide a sandwich structure for an accessory that can be obtained and can withstand long-term use.
すなわちこの発明の装身具の挟着構造は、一方の主装飾体と他方の挟着部材とに一対の取付脚部と取付基部とを形成するとともに、前記一対の取付脚部と取付基部との間に３枚以上の金属板材を介装してこれらを軸着するとともに、前記金属板材とともに該軸部を加締めてなる装身具の挟着構造であって、当該加締めの際に前記取付脚部と取付基部とに接する前記３枚以上の金属板材の両側のものは前記取付脚部と取付基部に強固に係合しており、また中間の金属板材はフリーの状態であって両側の金属板材とバネ性をもって押し合うように接合しており、一方の主装飾体と他方の挟着部材とにそれぞれ形成された取付脚部と取付基部とが相対的に回動する際、前記各金属板材の接合面に負荷がかかるようにしたことを特徴とするものである。 That is, according to the sandwiching structure of the accessory of the present invention, a pair of mounting legs and a mounting base are formed on one main decorative body and the other sandwiching member, and between the pair of mounting legs and the mounting base. 3 or more metal plate members are interposed between the metal plate members, and the shaft portion is crimped together with the metal plate material, and the attachment leg portion is clamped. The metal plate members on both sides of the three or more metal plates that are in contact with the mounting base are firmly engaged with the mounting legs and the mounting base, and the intermediate metal plate is in a free state and the metal plates on both sides When the mounting leg and the mounting base formed on one main decorative body and the other sandwiching member rotate relatively, the metal plate members It is characterized in that a load is applied to the joint surface of
この発明の装身具の挟着構造において、前記金属板材は、前記軸部を加締める際に変形する力を受け、したがって前記各金属板材の接合面は不均一な係合部分を備えており、接合時に力が分散されて前記バネ性が長持ちするようにしたことをも特徴とするものである。 In the sandwiching structure for an accessory according to the present invention, the metal plate member receives a force that deforms when the shaft portion is caulked, and therefore, the joining surface of each metal plate member has a non-uniform engagement portion. It is also characterized in that the force is sometimes dispersed to make the spring property last longer.
この発明の装身具の挟着構造において、前記金属板材は、その厚さを０．０５～０．２５ｍｍの範囲のものとしたことをも特徴とするものである。 In the jewelry sandwiching structure according to the present invention, the thickness of the metal plate is in the range of 0.05 to 0.25 mm.
以上のようにこの発明においては、前記取付脚部と取付基部との間に３枚以上の金属板材を介装するとともに、一対の取付脚部と取付基部に接する両端の金属板材をそれぞれ取付脚部と取付基部に強固に結合させ、一方の主装飾体と他方の挟着部材とにそれぞれ形成された取付脚部と取付基部とが相対的に回動する際、前記３枚以上の金属板材の両側のものは前記取付脚部と取付基部に強固に係合しており、また中間の金属板材はフリーの状態であって両側の金属板材とバネ性をもって押し合うように接合して当該接合面に負荷がかかるようにしたものである。 As described above, in the present invention, three or more metal plate materials are interposed between the mounting leg portion and the mounting base portion, and the pair of mounting leg portions and the metal plate materials at both ends in contact with the mounting base portion are respectively attached to the mounting leg portions. When the mounting legs and the mounting bases, which are formed on one main decorative body and the other sandwiching member, are relatively coupled to each other and the mounting base, the three or more metal plate members The both sides of the metal plate are firmly engaged with the mounting leg and the mounting base, and the intermediate metal plate is in a free state and joined so as to press against the metal plates on both sides with springiness. The load is applied to the surface.
そうすることによって、意外にも挟着力が大幅に向上し、しかもその挟着力が極めて長期間にわたって保持されるという顕著な効果を奏することが可能となり、この種の製品の弱点であった挟着力の持続に関する問題点を根本的に解消することに成功したのである。 By doing so, it is possible to achieve a remarkable effect that the clamping force is significantly improved and the clamping force is maintained for an extremely long period of time, and the clamping force that has been a weak point of this type of product. It has succeeded in fundamentally resolving the problems related to the sustainability.
この発明における装身具の挟着構造が、なぜ耳たぶへの挟着力が従来に比して飛躍的に高まり、しかもその挟着力が長期間一定に保持されることとなるのかは詳らかではないが、前記一対の取付脚部と取付基部とを軸着する際に、前記一対の取付脚部と取付基部に接する両端の金属板材はそれぞれ取付脚部と取付基部に噛み合って（食い込んで）強固に結合するものと考えられる。したがって、互いに結合した金属板材と取付脚部、金属板材と取付基部との間では回動操作が行われなくなる。
そのため、一方の主装飾体と他方の挟着部材とにそれぞれ形成された取付脚部と取付基部とが相対的に回動する際、前記中間の金属板材がフリーの状態で各金属板材の接合面に負荷がかかるようになっている。
このように、前記一対の取付脚部と取付基部に接する両端の金属板材の無用な挙動をなくしたことにより、前記３枚以上の各金属板材の係合面にのみ負荷がかかるようになり、特に前記中間の金属板材との接合面が不均一となってバネ性が維持されるため、挟着力が長期間一定に保持されるという顕著な効果を奏することができるようになったものと考えられる。
ちなみに、従来の単にワッシャを介在させた装身具の挟着構造では、数十回～数百回くり返して開閉操作すると挟着力の低下が見られたのに対し、この発明における装身具の挟着構造ではそれ以上の開閉操作でも挟着力の低下がまったく見られず、挟着力自体も従来のワッシャ型の装身具の挟着構造よりも格段に優れていたのである。 The pinching structure of the accessory in this invention is not clear why the pinching force on the earlobe is dramatically increased compared to the prior art, and that the pinching force is kept constant for a long time, When the pair of mounting legs and the mounting base are pivotally attached, the metal plate members at both ends contacting the pair of mounting legs and the mounting base are engaged with the mounting legs and the mounting base, respectively, and are firmly coupled. It is considered a thing. Therefore, the rotation operation is not performed between the metal plate member and the attachment leg portion, and the metal plate member and the attachment base portion which are coupled to each other.
For this reason, when the mounting leg portion and the mounting base portion formed on one main decorative body and the other sandwiching member rotate relative to each other, the intermediate metal plate members are joined to each other in a free state. The surface is loaded.
Thus, by eliminating the unnecessary behavior of the metal plate members at both ends in contact with the pair of mounting legs and the mounting base, a load is applied only to the engagement surfaces of the three or more metal plate members, In particular, since the joining surface with the intermediate metal plate material is non-uniform and the spring property is maintained, it is considered that the remarkable effect that the clamping force is kept constant for a long period of time can be achieved. It is done.
By the way, in the conventional accessory sandwiching structure simply having a washer interposed, when the opening / closing operation is repeated several tens to several hundreds of times, the clamping force is reduced. Even when the opening / closing operation was further performed, no decrease in the clamping force was observed, and the clamping force itself was much better than the clamping structure of the conventional washer-type accessory.

前記主装飾体１の連結部分には一対の取付脚部３，４が一体に備えられ、これと対向して副装飾体２の連結部分には前記取付脚部３，４間に嵌り合う取付基部５が一体に形成されている。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment in the case of applying a jewelry sandwiching structure of the present invention to an earring will be described in more detail with reference to the drawings.
In the embodiment shown in FIG. 1 to FIG. 6, 1 is a main decoration body, 2 is a sub-decoration body as an earlobe clamping part, and its overall shape is substantially the same arc shape, and in the assembled state it is a ring shape In this example, a jewel 13 made of diamond or the like is attached to the front side. Of course, both may be worn with either side facing the front of the earlobe. As materials, gold (K-18, etc.), platinum, silver, etc. can be used.
A pair of mounting leg portions 3 and 4 are integrally provided in the connecting portion of the main decorative body 1, and the fitting portion is fitted between the mounting leg portions 3 and 4 in the connecting portion of the sub-decorating body 2 so as to be opposed thereto. The base 5 is integrally formed.
そして、これらに開けられた貫通孔６，７にピン８を挿通し、この部位を加締めることとなるが、この際、取付脚部３，４と取付基部５との間に、厚さ０．０５～０．２５ｍｍ、好ましくは厚さ０．１５ｍｍのステンレス製等の、クッション性のある３枚以上の金属板材９を介して加締めたものである。
前記金属板材９の厚さを０．０５～０．２５ｍｍの範囲のものとした理由は、０．０５ｍｍ以下の場合にその弾性が生かせなくなってしまうためである。また０．２５ｍｍ以上の場合には、金属板材９そのものの弾性がなくなってしまうためである。
金属板材９は３枚以上であればよいが、３枚であっても経済性や組み付けの作業性等には問題がなく、挟着力の持続性を勘案すれば３枚とすることが望ましい。
なお、符号１０，１１は主装飾体１および副装飾体２の端面に形成した耳当部である。 Then, the pin 8 is inserted into the through holes 6 and 7 opened in these, and this portion is caulked, but at this time, the thickness 0 between the mounting legs 3 and 4 and the mounting base 5 is reduced. It is caulked through three or more metal plates 9 having cushioning properties, such as stainless steel having a thickness of 0.05 to 0.25 mm, preferably 0.15 mm.
The reason why the thickness of the metal plate 9 is in the range of 0.05 to 0.25 mm is that the elasticity cannot be utilized when the thickness is 0.05 mm or less. Further, when the thickness is 0.25 mm or more, the elasticity of the metal plate 9 itself is lost.
The number of the metal plate members 9 may be three or more. However, even if the number is three, there is no problem in economic efficiency and assembling workability, and it is desirable that the number is three considering the sustainability of the clamping force.
Reference numerals 10 and 11 denote ear pads formed on the end surfaces of the main decorative body 1 and the auxiliary decorative body 2.
この実施例においては、前記金属板材９の面積は、図５および図６に示すように、前記一対の取付脚部３，４と取付基部５の輪郭内に収容される広さに形成されており、しかも一対の取付脚部３，４と取付基部５に接する両端の金属板材９をそれぞれ取付脚部３，４と取付基部５に強固に結合させてある。もちろん、前記金属板材９の面積が前記一対の取付脚部３，４と取付基部５の輪郭内に収容される広さを越えても、取付脚部３，４と取付基部５とに強固に結合できれば何ら問題はない。
このような結合方法としては、軸部を構成するピン８部分を加締める際に両側の硬質である金属板材９がそれより軟質素材の使われている取付脚部３，４と取付基部５に食い込むようにすることができる。また、両側の金属板材９の取付脚部３，４と取付基部５に接する面を粗面化したり、両側の金属板材９の外周面等に突起やバリを形成しておくこともできる。 In this embodiment, the area of the metal plate 9 is formed so as to be accommodated within the contours of the pair of mounting legs 3, 4 and the mounting base 5, as shown in FIGS. 5 and 6. In addition, the metal plate members 9 at both ends contacting the pair of mounting legs 3 and 4 and the mounting base 5 are firmly coupled to the mounting legs 3 and 4 and the mounting base 5 respectively. Of course, even if the area of the metal plate 9 exceeds the area accommodated in the outline of the pair of mounting legs 3 and 4 and the mounting base 5, the mounting legs 3 and 4 and the mounting base 5 are firmly attached. There is no problem if they can be combined.
As such a coupling method, when the pin 8 portion constituting the shaft portion is caulked, the metal plate material 9 which is hard on both sides is attached to the mounting leg portions 3 and 4 and the mounting base portion 5 where the soft material is used. Can be bitten. Moreover, the surface which touches the attachment leg parts 3 and 4 and the attachment base part 5 of the metal plate material 9 of both sides can be roughened, or a protrusion and a burr | flash can be formed in the outer peripheral surface etc. of the metal plate material 9 of both sides.
また、前記金属板材９が円形の場合であっても、打ち抜き等の際に真円になることはほとんどなく、その変形によって金属板材９をそれぞれ取付脚部３，４と取付基部５に強固に結合させ、かつ取付脚部３，４と取付基部５とが相対的に回動する際に一緒に回ってしまうことが防止できる。もちろん、金属板材９が四角等の多角形の場合には供廻り（ともまわり）を確実に防止することができる。
そして、一方の主装飾体１と他方の挟着部材２とにそれぞれ形成された取付脚部３，４と取付基部５とが相対的に回動する際、前記３枚以上の各金属板材９の係合面に重点的に負荷がかかるようになっている。 Further, even when the metal plate 9 is circular, it is rare to become a perfect circle upon punching or the like, and the deformation causes the metal plate 9 to be firmly attached to the mounting legs 3 and 4 and the mounting base 5 respectively. It is possible to prevent the attachment legs 3 and 4 and the attachment base 5 from rotating together when they are relatively rotated. Of course, when the metal plate 9 is a polygon such as a square, it is possible to reliably prevent the rotation (both rotations).
When the mounting legs 3 and 4 and the mounting base 5 formed on one main decorative body 1 and the other sandwiching member 2 are relatively rotated, each of the three or more metal plate members 9 is provided. A load is applied to the engaging surface of the main body.
なお図示はしないが、前記３枚以上の金属板材９は、前記軸部を構成するピン８部分を加締めた際に、自動的に軸周辺部分が内側に押し込まれるように変形する。
そして前記各金属板材９の係合面の接触による負荷と、このような変形に応じて不均一となった各金属板材９の係合面にかかる負荷とがあいまってバネ性が向上し、挟着力が長期間一定に保持されることとなるものと考えられる。 Although not shown, the three or more metal plate members 9 are deformed so that the peripheral portion of the shaft is automatically pushed inward when the pin 8 portion constituting the shaft portion is crimped.
The load due to the contact of the engagement surface of each metal plate 9 and the load applied to the engagement surface of each metal plate 9 that becomes non-uniform due to such deformation are combined to improve the spring property. It is considered that the wearing force is kept constant for a long time.
ちなみに、従来の単にワッシャを介在させた装身具の挟着構造では、数十回～数百回くり返して開閉操作すると挟着力の低下が見られたのに対し、この実施例における装身具の挟着構造ではそれ以上の開閉操作でも挟着力の低下がまったく見られず、挟着力自体も従来のワッシャ型の装身具の挟着構造よりも格段に優れていたのである。 By the way, in the conventional attachment structure of the jewelry simply interposing a washer, when the opening and closing operation was repeated several tens to several hundreds of times, the clamping force was reduced. However, even when the opening / closing operation was further performed, no decrease in the clamping force was observed, and the clamping force itself was much superior to the clamping structure of the conventional washer-type accessory.
この発明は以上の通り、一方の主装飾体と他方の挟着部材とにそれぞれ形成された取付脚部と取付基部とが相対的に回動する際、前記中間の金属板材がフリーな状態となって各金属板材の係合面にかかる負荷がばらつくこととなってバネ性が向上し、挟着力が長期間一定に保持されるようにしたものである。
したがって、図示したような円弧状の挟着部材を用いた場合のみならず、その他のデザインや、ピアス用のピンを設けたイヤリングの挟着構造、フリーサイズの指輪、ブレスレット等にも適用可能であることはいうまでもない。 As described above, when the mounting leg portion and the mounting base portion respectively formed on one main decorative body and the other sandwiching member are relatively rotated, the intermediate metal plate material is free. Thus, the load applied to the engagement surface of each metal plate material varies, so that the spring property is improved and the clamping force is kept constant for a long period of time.
Therefore, it is applicable not only to the case where the arc-shaped pinching member as shown in the figure is used, but also to other designs, pinching structures of earrings provided with pins for piercing, free size rings, bracelets, etc. Needless to say.
