Description
【０００１】[0001]
本考案は、特に、ニッケル・チタン系の超弾性合金部品を含む金属製眼鏡フレ ームの改良に関するものである。 The present invention particularly relates to improvement of a metal spectacle frame including a nickel-titanium-based superelastic alloy component.
【０００２】[0002]
近年は、その機能性や意匠性の優秀さなどから、種々の金属製眼鏡フレームが 提供されているが、その中でも、特に、ニッケル・チタン系の超弾性合金を利用 した眼鏡フレームが大いに脚光を浴びている。それは、このニッケル・チタン系 合金の超弾性により、掛け心地の良さは勿論のこと、各部品の原形への回復力・ 原形の維持力等が期待できるので、例え、不測の外力が加わっても、型くずれし たり壊れたりする心配が少ない利点を有するからである。 In recent years, various metal eyeglass frames have been provided due to their excellent functionality and design, and among them, eyeglass frames that use nickel-titanium-based superelastic alloys are particularly popular. Taking a bath. Because of the super elasticity of this nickel-titanium alloy, it can be expected not only to be comfortable to wear, but also to be able to restore each component to its original shape, maintain its original shape, and so on, even if an unexpected external force is applied. This is because it has the advantage that there is little concern that it will lose its shape or break.
【０００３】 そして、この超弾性合金部品を含む金属製眼鏡フレームにあって、当該超弾性 部品を相手部品の対応個所に接合する場合には、相手部品が同種金属部品であっ ても異種金属部品であっても、通常は、この接合部位に金属キャップをカシメに より固定して、当該金属キャップを相手部品にろう付けするか、或いは、特開昭 ６３−２１４７１６号公報等に示す如く、超弾性合金部品の接合部位にろう付け に馴染む金属材料のメッキを施し、当該メッキ層を利用して、相手部品にろう付 けすることにより、眼鏡フレームを組み立てている。In a metal spectacle frame including the superelastic alloy component, when the superelastic component is joined to a corresponding portion of the mating component, even if the mating component is the same metal component, the dissimilar metal component is used. However, usually, a metal cap is fixed to this joint portion by caulking, and the metal cap is brazed to a mating component, or, as shown in JP-A-63-214716, etc. The joint parts of the elastic alloy parts are plated with a metal material that is suitable for brazing, and the spectacle frame is assembled by brazing the mating parts using the plating layer.
【０００４】[0004]
然し乍ら、従来にあっては、斯る全ての超弾性合金部品を任意断面形状の単線 材で構成して、該超弾性合金部品の接合部位を相手部品にろう付けする関係で、 超弾性合金部品に大きな捻じり力等が加わると、特に、その接合部に応力が集中 して、折損してしまう恐れを十分に有していた。しかも、接合部はろう付けによ る熱影響を受けて脆弱となっているので、この点からも、折損が助長されること となる。 従って、折角、原形への回復力・原形の維持力等が期待できる超弾性に着目し て、超弾性合金を部品の一部に利用したにも拘らず、従来にあっては、この接合 部又はその近傍の折損により、超弾性効果を大いに発揮させることができなくな ってしまう大きな問題点を有していた。 However, in the past, all such superelastic alloy parts were made of a single wire having an arbitrary cross-sectional shape, and the joining portion of the superelastic alloy part was brazed to the mating part, so that the superelastic alloy part was manufactured. If a large twisting force is applied to the joint, the stress is concentrated especially on the joint, and there is a sufficient risk of breakage. In addition, the joint is vulnerable to the heat of brazing, which also promotes breakage. Therefore, in spite of using superelastic alloys as part of parts, focusing on superelasticity that can be expected to be bent, recovery to original shape, maintenance of original shape, etc. Or, there was a big problem that the superelastic effect could not be fully exerted due to breakage in the vicinity thereof.
【０００５】[0005]
本考案は、斯る従来の金属製眼鏡フレームの課題を有効に解決するために開発 されたもので、超弾性合金部品を含む金属部品同士の接合により組み立てられる 金属製眼鏡フレームを前提として、上記超弾性合金部品を、少なくとも、その一 部に超弾性合金線材を有する撚り線構造となす構成を採用した。 The present invention was developed in order to effectively solve the problems of the conventional metal eyeglass frames, and is based on the premise that the metal eyeglass frames are assembled by joining metal parts including superelastic alloy parts. At least a part of the superelastic alloy component has a stranded wire structure having a superelastic alloy wire rod.
【０００６】[0006]
依って、本考案にあっては、全ての超弾性合金部品が一部に超弾性合金線材を 有する撚り線構造となっているので、例え、当該部品に大きな捻じり力が加わっ ても、その撚り線相互間に働く減衰作用で、接合部に対する応力の集中を効果的 に緩和して、従来の如く、接合部又はその近傍からの折損を有効に防止すること が可能となる。 従って、超弾性効果を十二分に発揮できる金属製眼鏡フレームを初めて提供で きる訳である。 Therefore, in the present invention, since all superelastic alloy parts have a stranded wire structure having a part of the superelastic alloy wire, even if a large twisting force is applied to the parts, With the damping action that acts between the twisted wires, it is possible to effectively alleviate the concentration of stress on the joint, and to effectively prevent breakage from the joint or its vicinity as in the conventional case. Therefore, it is the first time to provide a metal spectacle frame capable of fully exerting the superelastic effect.
【０００７】[0007]
以下、本考案を図示する一実施例に基づいて詳述する。 まず、実施例に係る金属製眼鏡フレームの基本構成を説明すると、本実施例に あっても、一応、図１に示す如く、一対のリム１の内側に架橋されるブレースバ ー２・ブリッジ３と、各リム１の外側に設けられる一対のテンプル４とを、超弾 性合金で成形することを前提とするものであるが、その他リム１やパッド足５な どの部品をも上記超弾性合金で成形することを否定するものではない。又、超弾 性合金については、超弾性を有するニッケル・チタン系の形状記憶合金を使用す るものとする。 Hereinafter, the present invention will be described in detail with reference to an illustrated embodiment. First, the basic configuration of the metal spectacle frame according to the embodiment will be described. Even in the embodiment, as shown in FIG. 1, a brace bar 2 and a bridge 3 that are bridged inside a pair of rims 1 are provided. It is assumed that the pair of temples 4 provided on the outer side of each rim 1 are formed of a super elastic alloy, but other parts such as the rim 1 and the pad foot 5 are also made of the above super elastic alloy. It does not deny molding. As for the superelastic alloy, nickel-titanium type shape memory alloy having superelasticity shall be used.
【０００８】 そして、本実施例は、斯る構成を前提として、上記のブレースバー２・ブリッ ジ３及びテンプル４に関して、従来と異なり、任意本数の超弾性合金線材Ｓ１か ら成る撚り線で構成すると共に、該撚り線構造の各部品２・３・４の接合部位に 、ろう付けに馴染む金属材料、例えば、ステンレス鋼等の金属材料で成形された 密着コイルばね６を外嵌して、該密着コイルばね６をリム１の対応個所にろう付 けせんとするものである。On the premise of this structure, the present embodiment is different from the conventional one in that the brace bar 2, the bridge 3 and the temple 4 are composed of twisted wires made of an arbitrary number of superelastic alloy wire rods S1. At the same time, the contact coil spring 6 formed of a metal material familiar to brazing, for example, a metal material such as stainless steel is externally fitted to the joint portion of each of the parts 2, 3 and 4 of the stranded wire structure, The contact coil spring 6 is brazed to the corresponding portion of the rim 1.
【０００９】 そこで、便宜上、ブレースバー２を取り上げて具体的に説明すると、上記密着 コイルばね６の内径をブレースバー２の接合端部を緊密に嵌入できる大きさに設 定して、該密着コイルばね６の内径を強制的に拡げながら、図２に示す如く、内 部に超弾性合金の撚り線から成るブレースバー２の接合端部を嵌入すると、その 撚り線端部を不用意にバラケさせることなく、密着コイルばね６がブレースバー ２の接合端部に緊密強固に外嵌されるので、後は、この密着コイルばね６をリム １の対応個所にろう付け７すれば、従来の如き金属キャップやメッキ層を利用し なくとも、図３に示す如く、ブレースバー２がリム１に必要な強度を伴って確実 に接合される。 従って、後は、ブリッジ３やテンプル４についても、具体的には図示しないが 、これと同様に、その接合部位に密着コイルばね６を緊密強固に外嵌して、リム １の対応個所にろう付け７すれば、これにより、図１に示す金属製眼鏡フレーム が確実に組み立てられることとなる。Therefore, for the sake of convenience, the brace bar 2 will be specifically described. The inner diameter of the close contact coil spring 6 is set to a size that allows the joint end portion of the brace bar 2 to be tightly fitted, and the close contact coil 2 is As shown in FIG. 2, by forcibly expanding the inner diameter of the spring 6, if the joint end of the brace bar 2 made of a stranded wire of a superelastic alloy is fitted inside, the end of the stranded wire will be unintentionally scattered. Since the contact coil spring 6 is tightly and tightly fitted onto the joint end portion of the brace bar 2 without any need, if the contact coil spring 6 is brazed 7 to the corresponding portion of the rim 1 thereafter, it is possible to perform the same operation as the conventional metal. As shown in FIG. 3, the brace bar 2 is securely joined to the rim 1 with the necessary strength without using a cap or a plating layer. Therefore, after that, although not specifically shown, the bridge 3 and the temple 4 are also fitted with the close contact coil springs 6 tightly and firmly at their joints so that the bridge 3 and the temple 4 will be at the corresponding positions of the rim 1. By attaching 7, the metal spectacle frame shown in FIG. 1 can be reliably assembled.
【００１０】 又、本実施例の眼鏡フレームにあっても、超弾性が特に要求される部品、即ち 、ブレースバー２・ブリッジ３及びテンプル４を超弾性合金で成形している関係 で、不測の外力等が加わっても、原形への回復力・原形の維持力を発揮して、型 くずれしたり壊れたりする心配が少なくなることは言うまでもないが、特に、各 部品２・３・４が任意本数の超弾性合金線材Ｓ１から成る撚り線構造を呈してい る関係で、例え、当該部品２・３・４に大きな捻じり力が加わっても、その撚り 線相互間に働く減衰作用で、接合部に対する応力の集中を効果的に緩和できるの で、従来の如く、接合部又はその近傍から折損してしまうことを有効に防止する ことが可能となる訳である。Even in the spectacle frame of this embodiment, it is unexpected because the parts for which superelasticity is particularly required, that is, the brace bar 2, the bridge 3, and the temple 4 are formed of a superelastic alloy. Needless to say, even if external force is applied, the ability to recover to the original shape and the ability to maintain the original shape are exerted, and there is less concern that the shape will be lost or broken, but in particular, each part 2, 3, 4 is optional. Due to the stranded wire structure consisting of the number of superelastic alloy wire rods S1, even if a large twisting force is applied to the parts 2, 3 and 4, the joining action is caused by the damping action acting between the stranded wires. Since the concentration of stress on the joint can be effectively relieved, it is possible to effectively prevent breakage from the joint or the vicinity thereof as in the conventional case.
【００１１】 尚、上記の実施例における撚り線構造は、撚り線の全てを超弾性合金線材Ｓ１ で構成したものであるが、本考案はこれに限定されるものではなく、例えば、図 ４の（Ａ）に示す如く、撚り線の中心部の線材に超弾性合金線材Ｓ１を使用し、 外周部の線材にステンレス線材Ｓ２等を使用するか、或いは、図４の（Ｂ）に示 す如く、超弾性合金線材Ｓ１とステンレス線材Ｓ２等を交互に適宜組み合わせて 使用して、接合部に対する応力の集中を効果的に緩和できる撚り線構造を得るこ とも実施に応じ任意である。 但し、この場合にも、撚り線端部の固定には、金属キャップ等の公知手段の使 用を否定するものではないが、上記の密着コイルばね６を使用すれば、撚り線端 部をバラケされることなく確実に固定できるので、極めて最適となる。In the stranded wire structure in the above-mentioned embodiment, all of the stranded wires are made of the super elastic alloy wire rod S1, but the present invention is not limited to this, and for example, as shown in FIG. As shown in (A), a super elastic alloy wire S1 is used for the wire at the center of the stranded wire, and a stainless wire S2 or the like is used for the wire at the outer circumference, or as shown in (B) of FIG. It is also optional to obtain a stranded wire structure capable of effectively relieving the stress concentration on the joint by using the super elastic alloy wire rod S1 and the stainless wire rod S2 in combination appropriately. However, even in this case, use of a known means such as a metal cap is not denied to fix the end of the stranded wire. However, if the above-mentioned close contact coil spring 6 is used, the end of the stranded wire can be dispersed. It is extremely optimal because it can be securely fixed without being damaged.
【００１２】[0012]
以上の如く、本考案は、上記構成の採用により、例え、超弾性合金部品に大き な捻じり力等が加わっても、その撚り線相互間に働く減衰作用で、接合部に対す る応力の集中を効果的に緩和して、従来の如く、接合部又はその近傍からの折損 を有効に防止することが可能となるので、超弾性効果を十二分に発揮できる金属 製眼鏡フレームを初めて提供できることとなった。 As described above, according to the present invention, by adopting the above configuration, even if a large twisting force is applied to the superelastic alloy component, the damping action that acts between the twisted wires causes the stress to be applied to the joint portion. Since it is possible to effectively alleviate the concentration and effectively prevent breakage from the joint or its vicinity as in the past, it is the first time to provide a metal eyeglass frame that can fully exhibit the superelastic effect. It became possible.
