テンプルは、眼鏡を顔面に安定して掛けるための眼鏡部品である。最近は様々な素材があり、その選択肢も広がっている。加工のしやすさやコストが安いなどの理由からプラスチックや合成樹脂を用いたテンプルがある一方、豪華さを醸し出すために金製や宝石を埋め込んだテンプルなどがある。金属製の素材は丈夫で弾力性があるといったメリットがある反面、重く、アレルギー源になるなどのマイナス面もある。金だけで作ったテンプルは上記の金属のマイナス面をカバーできるが、強度の面で問題があり、また金だけを用いたテンプルは高価すぎるなどの問題点もある。そこで注目を浴びている金属としてチタンあるいはやチタン合金がある。チタンは丈夫で軽い金属であり、アレルギー源となることもないなどの利点がある。チタン製の時計に人気が集まっているのも、このような理由からである。
【０００４】
しかしチタン自体、見た目は地味である。しかも金のように、選択した金属によってはロー付けが難しい。そこで、チタンを使用したテンプルに金を装飾したい場合には、チタンに溝を彫り、金を埋め込んでかしめるといった方法が採られている。『異種金属複合眼鏡枠』（特許文献１）では、装飾となる中空の貴金属部材を眼鏡枠用金属部材に差し込み、嵌合部をプレス接合することによって異種金属の接合を行っている。また『チタン・ニッケル合金製部品と異種金属部品との接合方法』（特許文献２）では、チタン・ニッケル合金部品の接合部を厚肉に成形して、この厚肉の接合部を異種金属部品の所定部位に当て、厚肉接合部を高温度に発熱して溶接している。
【０００５】
【発明が解決しようとする課題】
金属製のテンプルは丈夫であり、弾力性もある。しかし、一般に重い、錆やすいなどの欠点がある。これに対してチタンあるいはその合金は軽く、錆びにくいという利点がある。しかも金属アレルギーを起こすことがないので、金属アレルギーのある人にも優しい素材となっている。
【０００６】
しかし、チタンあるいはその合金には、他の金属とロー付けしにくいという欠点がある。このようなマイナス面を解決した発明として、従来技術で挙げた『異種金属複合眼鏡枠』や『チタン・ニッケル合金製部品と異種金属部品との接合方法』などがある。
【０００７】
それぞれの技術にはそれぞれのメリットもあるが、またマイナス面もある。例えば『チタン・ニッケル合金製部品と異種金属部品との接合方法』では高電圧を用いなければならないし、窪みを彫って埋め込む方法では細かな作業が必要となるなどのマイナス面がある。
【０００８】
そこで本発明が解決しようとする課題は、組立細工が容易であり、どのような異種金属同士でも組み合わせることができる方法を提唱することである。また本発明では、装飾用となる金属を容易に取り替えられることも念頭に置いている。
【０００９】
【課題を解決するための手段】
上記の課題を解決するために、本発明では、テンプルをテンプルの主体となる部材に装飾用の部材を取り付ける構造とする。ここでテンプルの主体となる部材を「テンプル主体部材」または略して「主体部材」と呼び、装飾用の部材を「装飾部材」と呼ぶ。双方とも金属であり、主体部材は丈夫で軽く、弾力性のある金属を選び、装飾部材には貴金属を選ぶ。例えば前者はチタン、後者は金などである。このような異種金属は直接ロー付けすることが難しいために、本発明では装飾部材にもコマ部を設け、主体部材のコマとともにネジ留めあるいはピン留めによってヨロイに装着してヒンジ機構を形成し、装飾部材の他端を固定部材を用い主体部材と固定する。具体的には以下の構造のテンプルとなっている。
【００１０】
眼鏡のテンプルの主体となる金属と装飾部材とからなる、それぞれが異なる金属を組み合わせて構成されたテンプルにおいて、装飾部材の一端をコマ構造にし、該装飾部材のコマと主体部材のコマとでヨロイのコマを挟んでネジやピンなどで留めてヒンジ機構を構成するとともに、装飾部材のコマと逆方向の端を固定部材を用いてテンプル主体部材に固定する。ただし、装飾部材の交換を容易にするためには、コマ部の固定にネジを用いることが好ましい。
【００１１】
固定部材で固定させる部分を、固定部材を用いずに直接装飾部材を主体部材に巻き付けて固定することもできるが、見た目に見栄えがしない。このため、本発明では固定部材を用いている。その意味において、固定部材そのものも装飾の意味合いがあり、様々なデザインの固定部材が考えられる。固定部材の基本的に構造は以下の二通りある。
【００１２】
固定部材においては、主体部材を差し込む貫通孔と、装飾部材の先端を差し込む嵌合穴とから構成された構造を基本とする。固定部材で装飾部材を主体部材に取り付けるには、固定部材の貫通孔に主体部材を差し込み、かつ装飾部材の先端を嵌合穴に嵌合し、貫通孔の部分をかしめやロー付けなどする。
【００１３】
もう一つの固定部材は溝と、溝の逆面に窪みを持つ構造としたものである。この固定部材で装飾部材と主体部材を安定的に固定するには、固定部材の溝に主体部材を嵌合させ、装飾部材の先端を固定部材の窪みに差し込む。すなわち、固定部材は装飾部材と主体部材の弾性力で挟む形になる。この構造の固定部材では、宝石や様々な色や形状の金属部材以外の素材も使用することができる。
【００１４】
後者の固定部材の場合には、装飾部材と主体部材で固定部材を挟む形になっている。従って、より安定的に装飾部材を固定するために、補強部材を使用する。補強部材はピン形状であり、主体部材のコマ近辺にピンをロー付けし、ピンの先端を予め装飾部材に設けた凹に差し込み、コマをネジやピンで留める。これにより、装飾部材と主体部材間の捻れ方向の力に対する補強となる。もう一つの構造は補強部材を使用しないで、予め主体部材に凸部と装飾部材に凹部を設けておき、凸部を凹部に噛み合わせて捻れ方向に対する補強を行う方法である。もちろん、凸部を装飾部材に設け、凹部を主体部材に設ける形でもよいが、一般に主体部材の方が丈夫な金属であるために、前者の方が優れている。
【００１５】
【発明の実施の形態】
本発明の実施の形態を図を用いて説明する。図１は、コマ部の基本構造である。（ａ）はネジ留め前、（ｂ）はネジ留め後である。テンプル1はテンプル主体部材2（主体部材）と装飾部材3とから構成される。コマの構造は必ずしも図の通りである必要はなく、図は一例として挙げてある。主体部材のコマ210はネジ孔211と開き止め212からなり、装飾部材はコマ310とネジ孔311とからなる。また眼鏡のフロント枠と連結しているヨロイ4のコマ410はネジ孔411と開き止め412とから構成されている。各孔をあわせてネジ5で留めれば、コマによってテンプルが開閉する（ヒンジ機構）。ただしヨロイの開き止め412と主体部材の開き止め212によって約９０゜以上は開かない。（ｂ）はテンプルを一杯に開いた状態であり、双方の開き止めによって、これ以上矢印の方向（図の拡開方向）に動かない状態である。
【００１６】
図２の（ａ）は、固定部材の基本構造である。固定部材6は貫通孔610と嵌合穴620からなり、（ｂ）で示すように主体部材2を貫通孔610に通し、装飾部材3を嵌合穴620に差し込む。装飾部材の先端が嵌合穴の底621に届いてもよいし、届かなくてもよい。ただし必ず一部が嵌合穴に差し込まれていなければならない。また主体部材の入口と出口の所をロー付け、接着剤あるいはかしめるなどして、装飾部材が主体部材の上を滑らないようにする。図では貫通孔も嵌合穴も円筒形にしているが、主体部材と装飾部材の形状に合わせた形状にする。ロー付けの場合には、固定部材は主体部材にロー付けしやすい素材を選ぶ必要がある。またかしめる場合には、主体部材の貫通部（貫通孔610の位置）に切り欠きを入れておき、主体部材を貫通孔に挿入後、貫通孔を潰して主体部材に固定部材を固定させる方法を採ってもよい。以上、コマ部と固定部材によって装飾部材は主体部材に安定的に固定され、主体部材とともに開閉する。
【００１７】
図２の形状の固定部材ではあまりにも味気ない。そこで様々なデザインを施した固定部材を用いれば、固定部材そのものを装飾とすることもできる。例えば、図３は鞍形デザインの固定部材6の例である。貫通孔610に主体部材2を通し、嵌合穴620の底621に届くまで装飾部材3を差し込む。一方、コマ部をネジ留めすれば、異種金属組み合わせテンプルが完成する。図４は完成図である。レンズ7にヨロイ4が装着され、コマ410が主体部材2のコマ210と装飾部材3のコマ310とともにネジ留めされている。装飾部材は変形した“く”の字形に折り曲げられ、固定部材6の付近で主体部材と接しながら固定部材の嵌合穴に嵌合されている（図のｌ、ｍは切断位置で、（Ｌ）、（Ｍ）はｌ、ｍに対応した断面図である）。なお110はテンプルエンドで、合成樹脂などをかぶせた「モダン」と呼ばれる部分である。
【００１８】
図５は合成樹脂や宝石などの素材で作った固定部材である。（ａ）において、固定部材6に溝630と窪み640を彫っておく。組み立てるときに、溝630に主体部材2を合わせ、自然な滑らかな曲線で描かれた窪み640に装飾部材3の先端を挿入して固定部材6を押さえる形にする。この例ではヨロイ方向に装飾部材と主体部材に捻りを入れて弾性力を生んでいる。図６は図５の固定部材を用いて装飾部材を取り付け組み立てた異種金属組み合わせテンプルの側面図である。基本的に図４と同じであるが、主体部材2と装飾部材3を捻ってあることと、固定部材6が窪み640と溝630からなる構造をしている点が異なる。ｌ断面は固定部材のほぼ中央部で、ｍ断面は装飾部材の先端が窪みに触れる辺りで、それぞれの部材を切断したときの断面の様子を表している。固定部材は主体部材と装飾部材の弾性力で固定され、溝と窪みによって装飾部材が主体部材から外れることを防いでいる。図７に上面図と正面図を載せておく。なお上面図は眼鏡を掛けたときの頭上方向から見た図であり、正面図は眼鏡を掛けた人の顔の外部正面から見た図である。
【００１９】
上記の例では捻れを入れてあるが、必ずしも捻れは必要ない。大切なことは、主体部材と装飾部材の弾性力で安定的に挟み込むことである。捻れを使わない例は実施例で挙げる。弾性力を利用するために、場合によってはコマの部分にもその力が及び、コマの回転を悪くすることがある。また固定部材での留めが弾性力のみであるから、捻れ方向に弱い場合がある。そこで、コマ付近に補強部材を使って捻れ防止とコマへの必要以上の力が掛からないようにする。その例が図８である。（ａ）に示すように、主体部材2に凸部213を設け、装飾部材3に凸部に対応する凹部313を設けておく。組立は簡単で、凸部213を凹部313に挿入し、コマ210、310、410をネジ5で留めるだけでよい。（ｂ）は完成図である。なお凸部はピンを主体部材にロー付けしたものを使用してもよい。
【００２０】
【実施例】
固定部材のデザインや、装飾部材の素材、デザインなどに様々なバリエーションを持たせることによって、個々の顧客の好みに合わせた飾りができる。図９は貫通孔を有する固定部材の例である。この例では主体部材2にチタン、装飾部材3に金（Ｋ１８）を使用している。構造的には図４と同じで、固定部材6のデザインのみが違っている。なお参考のため、寸法を載せておく。数値の単位はミリメーター（mm）である。
【００２１】
図１０の固定部材は、貫通孔と溝を組み合わせた例である。固定部材6の主体部材2側が貫通孔の途中から溝になっている。装飾部材3側は窪みになっている。窪みは穴（装飾部材の先端部を隙間なく嵌合させる穴）であってもよい。図１１は、図１０で使用している固定部材の構造を説明するための側面図（テンプルを顔に掛けたときの横顔方向から見た図）である。（ａ）は固定部材を側面から見た図で、630の左側（ヨロイ側）が貫通孔、右側（テンプルエンド側）が溝になっている。一方、窪み640（どちらかと言えば嵌合穴に近い形状）はヨロイとは反対側に設けてあり、装飾部材を引っかけられる形になっている。（ｂ）は主体部材と装飾部材を取り付けた図である。固定部材を主体部材にロー付けすれば安定的に固定できるが、図のままでも装飾部材と主体部材の弾性力で固定することができる。より安定させるには、図１２に示すように固定部材6の外周形状に合わせて装飾部材3を曲げて挟持部312を作れば、固定部材を抱えるような形になるために安定する。宝石や飾り玉などの固定部材を使う場合などのように、主体部材にロー付けのできない固定部材を使用する場合には、この方法は適している。
【００２２】
図１０では捻れを入れていない。捻れを入れなくても、金属素材の弾力性だけでもある程度固定部材を押さえられる。しかも貫通孔と挟持部とによって、安定した固定が可能となる。固定部材の素材として金を使用した場合には加工がしやすいために、図１２に示す挟持部312に対応した固定部材の位置に浅い溝を入れてもよい。主体部材をチタン、装飾部材と固定部材を金にすることによって、金の豪華さをよりいっそう演出することができる。主体部材がチタンであるから、丈夫で軽いテンプルとすることができる。
【００２３】
【発明の効果】
本発明は異種金属を組み合わせたテンプルに関するものである。異種金属を組み合わせることによって、テンプル主体部材に丈夫で軽い金属を用い、装飾部材に豪華さを演出する飾り用の金属を用いることによって、装飾性に富み、軽くて丈夫なテンプルを成形することができる。例えば主体部材にチタンあるいはチタン合金を用い、装飾部材に金を用いることによって、チタンの丈夫さと金の豪華さをもつテンプルとすることができる。
【００２４】
しかし、チタンと金はロー付けが難しい。その点、本発明ではコマと固定部材で装飾部材を固定する方法を採っているために、装飾部材と主体部材を直接ロー付けする必要はない。また装飾部材は固定部材に差し込む方法を採っているために、固定部材と主体部材がロー付けされていても、装飾部材を好みに合わせて容易に交換できる。
【００２５】
固定部材は装飾部材を安定的に主体部材に装着するために用いるものであるが、固定部材そのものも飾りとすることができる。例えば上記に挙げたいくつかの例のように、主体部材との接触部を溝形にした形態では、固定部材そのものが交換できるために、装着者は固定部材を複数買い求め、その日の好みに合わせて固定部材を交換することもできる。貫通孔の場合にはテンプルエンド側で外さなければならないため、個人が簡単に固定部材を交換することは難しい。しかしモダンを外せばよいので、交換が不可能ではない。溝形の場合には、この点の問題もなく、素人にも容易に交換できる。

[Technical field to which the invention belongs]
The present invention relates to a temple configured by combining different metals and glasses using the temple. Specifically, the present invention relates to a temple provided with a means for decorating a temple by combining dissimilar metals that are difficult to braze with each other, such as titanium and gold, or a titanium alloy and gold, and glasses using the temple.
[0002]
[Prior art]
[Patent Document 1]
JP 2001-350120 A [Patent Document 2]
Japanese Patent Laid-Open No. 05-050268
The temple is a spectacle component for stably putting spectacles on the face. There are various materials these days, and the choices are expanding. There are temples using plastic or synthetic resin for reasons such as ease of processing and low cost, while there are temples made of gold or gemstones for luxury. Metal materials have the advantage of being strong and elastic, but they have the downside of being heavy and allergenic. A temple made only of gold can cover the negative side of the above-mentioned metal, but there is a problem in strength, and a temple using only gold is also too expensive. Therefore, there is titanium or a titanium alloy as a metal that is attracting attention. Titanium is a strong and light metal and has the advantage of not becoming a source of allergies. This is why titanium watches are gaining popularity.
[0004]
However, titanium itself is plain. Moreover, depending on the metal selected, such as gold, brazing is difficult. Therefore, when it is desired to decorate gold on a temple using titanium, a method of carving a groove in titanium and embedding gold is adopted. In the “dissimilar metal composite spectacle frame” (Patent Document 1), a hollow noble metal member serving as a decoration is inserted into a spectacle frame metal member, and a fitting portion is press-bonded to bond dissimilar metals. Also, in “Method of joining titanium / nickel alloy parts and dissimilar metal parts” (Patent Document 2), the joining part of titanium / nickel alloy parts is formed to be thick and the thick joining part is dissimilar metal parts. The thick-walled joint is heated to a high temperature and welded.
[0005]
[Problems to be solved by the invention]
Metal temples are strong and elastic. However, there are generally disadvantages such as heavy and easy to rust. On the other hand, titanium or its alloy is advantageous in that it is light and hardly rusts. Moreover, since it does not cause metal allergies, it is a material that is kind to people with metal allergies.
[0006]
However, titanium or its alloys have the drawback of being difficult to braze with other metals. As inventions that solve such a negative aspect, there are “dissimilar metal composite spectacle frame” and “method of joining titanium / nickel alloy parts and dissimilar metal parts” mentioned in the prior art.
[0007]
Each technology has its own merits, but there are also downsides. For example, in the “joining method of titanium / nickel alloy parts and dissimilar metal parts”, a high voltage must be used, and the method of engraving and embedding a recess requires a fine work.
[0008]
Therefore, the problem to be solved by the present invention is to propose a method that can be easily assembled and combined with any dissimilar metals. The present invention also keeps in mind that the decorative metal can be easily replaced.
[0009]
[Means for Solving the Problems]
In order to solve the above-described problems, in the present invention, the temple has a structure in which a decorative member is attached to a member that is a main body of the temple. Here, the member that is the main body of the temple is referred to as “temple main body member” or abbreviated as “main body member”, and the decorative member is referred to as “decorative member”. Both are made of metal, the main member is strong, light and elastic, and the precious metal is selected for the decorative member. For example, the former is titanium and the latter is gold. Since it is difficult to directly braze such dissimilar metals, in the present invention, the decorative member is also provided with a top portion, and is attached to the armor by screwing or pinning together with the main member top to form a hinge mechanism, The other end of the decorative member is fixed to the main member using a fixing member. Specifically, the temple has the following structure.
[0010]
In a temple composed of a metal that is the main body of a temple of glasses and a decorative member, each of which is composed of different metals, one end of the decorative member has a frame structure, and the frame of the decorative member and the frame of the main member A hinge mechanism is formed by fastening the frame with screws or pins, and the end of the decorative member opposite to the frame is fixed to the temple main member using a fixing member. However, in order to facilitate replacement of the decorative member, it is preferable to use a screw for fixing the top part.
[0011]
The portion to be fixed by the fixing member can be directly wound around the main member without using the fixing member, but it does not look good. For this reason, the fixing member is used in the present invention. In that sense, the fixing member itself has the meaning of decoration, and fixing members of various designs are conceivable. There are basically the following two structures of the fixing member.
[0012]
The fixing member basically has a structure composed of a through hole into which the main member is inserted and a fitting hole into which the tip of the decorative member is inserted. In order to attach the decorative member to the main member with the fixing member, the main member is inserted into the through hole of the fixing member, the tip of the decorative member is fitted into the fitting hole, and the through hole portion is caulked or brazed.
[0013]
Another fixing member has a structure having a groove and a depression on the opposite surface of the groove. In order to stably fix the decorative member and the main member with the fixing member, the main member is fitted into the groove of the fixing member, and the tip of the decorative member is inserted into the recess of the fixing member. That is, the fixing member is sandwiched by the elastic force of the decorative member and the main member. In the fixing member of this structure, materials other than jewelry and metal members of various colors and shapes can be used.
[0014]
In the case of the latter fixing member, the fixing member is sandwiched between the decorative member and the main member. Therefore, in order to fix the decorative member more stably, the reinforcing member is used. The reinforcing member has a pin shape, and a pin is brazed around the top of the main member, the tip of the pin is inserted into a recess provided in advance in the decorative member, and the top is fastened with a screw or a pin. Thereby, it becomes reinforcement with respect to the force of the twist direction between a decoration member and a main body member. The other structure is a method in which a reinforcing member is provided in advance with a convex portion and a decorative member on which a concave portion is provided, and the convex portion is engaged with the concave portion to reinforce the twisting direction. Of course, the convex portion may be provided on the decorative member and the concave portion may be provided on the main member. However, since the main member is generally a stronger metal, the former is superior.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the basic structure of the frame section. (A) is before screwing, (b) is after screwing. The temple 1 includes a temple main member 2 (main member) and a decorative member 3. The frame structure does not necessarily have to be as shown in the figure, and the figure is given as an example. The main member piece 210 includes a screw hole 211 and an opening stopper 212, and the decorative member includes a piece 310 and a screw hole 311. Further, the frame 410 of the armor 4 connected to the front frame of the spectacles is composed of a screw hole 411 and an opening stopper 412. If the holes are combined and fastened with screws 5, the temple opens and closes with a frame (hinge mechanism). However, it cannot be opened more than about 90 ° by the end stop 412 of the armor and the end stop 212 of the main member. (B) is a state in which the temple is fully opened, and is not moved further in the direction of the arrow (the expanding direction in the figure) due to the two stoppers.
[0016]
FIG. 2A shows the basic structure of the fixing member. The fixing member 6 includes a through hole 610 and a fitting hole 620. The main member 2 is passed through the through hole 610 and the decorative member 3 is inserted into the fitting hole 620 as shown in FIG. The tip of the decorative member may or may not reach the bottom 621 of the fitting hole. However, it must be partly inserted into the fitting hole. In addition, the decorative member is prevented from slipping on the main member by brazing the inlet and the outlet of the main member and bonding or caulking. Although the through hole and the fitting hole are cylindrical in the figure, they are shaped according to the shapes of the main member and the decorative member. In the case of brazing, it is necessary to select a material that can be easily brazed to the main member for the fixing member. In the case of caulking, a method of fixing a fixing member to the main member by crushing the through-hole (the position of the through-hole 610) of the main member, inserting the main member into the through-hole, and then crushing the through-hole. May be taken. As described above, the decorative member is stably fixed to the main member by the top portion and the fixing member, and opens and closes together with the main member.
[0017]
The fixing member having the shape shown in FIG. Therefore, if fixing members having various designs are used, the fixing members themselves can be decorated. For example, FIG. 3 shows an example of a fixing member 6 having a saddle-shaped design. The main member 2 is passed through the through-hole 610, and the decorative member 3 is inserted until it reaches the bottom 621 of the fitting hole 620. On the other hand, if the frame part is screwed, a dissimilar metal combination temple is completed. FIG. 4 is a completed drawing. The lens 7 is equipped with the armor 4 and the frame 410 is screwed together with the frame 210 of the main member 2 and the frame 310 of the decorative member 3. The decorative member is bent into a deformed “<” shape, and is fitted in the fitting hole of the fixing member in contact with the main member in the vicinity of the fixing member 6 (l and m in the figure are cutting positions, (L ) And (M) are cross-sectional views corresponding to l and m). Reference numeral 110 denotes a temple end, which is a part called “modern” covered with a synthetic resin.
[0018]
FIG. 5 shows a fixing member made of a material such as synthetic resin or jewelry. In (a), a groove 630 and a recess 640 are carved in the fixing member 6. When assembling, the main body member 2 is aligned with the groove 630, and the tip of the decorative member 3 is inserted into the depression 640 drawn with a natural smooth curve so that the fixing member 6 is pressed. In this example, the decorative member and the main member are twisted in the alloy direction to generate an elastic force. FIG. 6 is a side view of a dissimilar metal combination temple in which a decorative member is attached and assembled using the fixing member of FIG. 4 is basically the same as FIG. 4 except that the main member 2 and the decorative member 3 are twisted and that the fixing member 6 has a structure composed of a recess 640 and a groove 630. The l cross section is the substantially central portion of the fixing member, and the m cross section is the area where the tip of the decorative member touches the dent, and represents the state of the cross section when each member is cut. The fixing member is fixed by the elastic force of the main member and the decorative member, and prevents the decorative member from being detached from the main member by the groove and the depression. FIG. 7 shows a top view and a front view. The top view is a view from the overhead direction when wearing glasses, and the front view is a view from the outside front of the face of the person wearing glasses.
[0019]
In the above example, a twist is included, but the twist is not necessarily required. What is important is to stably hold the elastic member between the main member and the decorative member. Examples that do not use twist are given in the examples. Since the elastic force is used, in some cases, the force may reach the top of the frame, and the rotation of the top may be deteriorated. In addition, since the fastening with the fixing member is only the elastic force, it may be weak in the twisting direction. Therefore, a reinforcing member is used in the vicinity of the top so that twisting is prevented and excessive force is not applied to the top. An example is shown in FIG. As shown in (a), the main member 2 is provided with a convex portion 213, and the decorative member 3 is provided with a concave portion 313 corresponding to the convex portion. Assembling is simple, it is only necessary to insert the convex portion 213 into the concave portion 313 and fasten the tops 210, 310, 410 with the screws 5. (B) is a completed drawing. In addition, you may use the convex part which brazed the pin to the main body member.
[0020]
【Example】
By giving various variations to the design of the fixing member and the material and design of the decorative member, it is possible to create decorations tailored to individual customer preferences. FIG. 9 shows an example of a fixing member having a through hole. In this example, the main member 2 is made of titanium, and the decorative member 3 is made of gold (K18). Structurally, it is the same as FIG. 4 and only the design of the fixing member 6 is different. For reference, the dimensions are listed. The unit of the numerical value is millimeter (mm).
[0021]
The fixing member in FIG. 10 is an example in which a through hole and a groove are combined. The main member 2 side of the fixing member 6 is a groove from the middle of the through hole. The decorative member 3 side is hollow. The depression may be a hole (a hole that fits the tip of the decorative member without a gap). FIG. 11 is a side view for explaining the structure of the fixing member used in FIG. 10 (viewed from the side face direction when the temple is hung on the face). (A) is the figure which looked at the fixing member from the side, and the left side (Yoroi side) of 630 is a through hole, and the right side (Temple end side) is a groove. On the other hand, the recess 640 (if any) is provided on the opposite side to the armor, and is shaped so that the decorative member can be hooked. (B) is the figure which attached the main body member and the decoration member. If the fixing member is brazed to the main member, it can be fixed stably, but it can be fixed by the elastic force of the decorative member and the main member as shown. In order to make it more stable, as shown in FIG. 12, if the holding member 312 is formed by bending the decorative member 3 in accordance with the outer peripheral shape of the fixing member 6, the shape becomes such that the holding member is held, so that the shape becomes stable. This method is suitable when a fixing member that cannot be brazed to the main member is used, such as when a fixing member such as a jewel or a decorative ball is used.
[0022]
In FIG. 10, no twist is applied. Even without twisting, the fixing member can be held down to some extent only by the elasticity of the metal material. In addition, stable fixation is possible by the through hole and the clamping portion. Since processing is easy when gold is used as the material of the fixing member, a shallow groove may be formed at the position of the fixing member corresponding to the holding portion 312 shown in FIG. By using titanium as the main member and gold as the decorative member and the fixing member, it is possible to further enhance the luxury of gold. Since the main member is titanium, a strong and light temple can be obtained.

【The invention's effect】
The present invention relates to a temple combining different metals. By combining dissimilar metals, a strong and light metal can be used for the main body of the temple, and a decorative metal that can be used to decorate the decorative member can be used to form a light and durable temple. it can. For example, by using titanium or a titanium alloy as a main member and using gold as a decorative member, a temple having titanium durability and gold luxury can be obtained.
[0024]
However, titanium and gold are difficult to braze. In that respect, in the present invention, since the decorative member is fixed by the frame and the fixing member, it is not necessary to braze the decorative member and the main member directly. Moreover, since the decoration member employ | adopts the method of inserting in a fixing member, even if a fixing member and a main body member are brazed, a decoration member can be easily replaced | exchanged according to liking.
[0025]
The fixing member is used to stably attach the decorative member to the main member, but the fixing member itself can also be used as a decoration. For example, as in the above-mentioned examples, in the form in which the contact portion with the main member is grooved, the fixing member itself can be replaced. Therefore, the wearer purchases a plurality of fixing members and matches the preference of the day. The fixing member can be exchanged. In the case of a through hole, it must be removed on the temple end side, so it is difficult for an individual to easily replace the fixing member. However, it is not impossible to replace it because it is only necessary to remove modernity. In the case of the groove shape, there is no problem with this point, and it can be easily replaced by an amateur.
