Description
上記課題を解決するために請求項１に記載の眼鏡用テンプルは、複数本の金属線を撚り合わせてなる金属撚り線から形成され、湾曲状の耳掛け部分を有する眼鏡用テンプルにおいて、前記金属撚り線の周囲から押圧力を付与することで前記金属線を塑性変形させて形成された前記金属線間の隙間と、前記隙間部分で前記金属撚り線を湾曲状に変形させた湾曲部分とを有する。
本発明では、金属線間に形成された隙間によって金属撚り線を湾曲状に変形させることが容易になり、芯材など別の形状維持部材は不要になる。もちろん、金属撚り線を構成する金属線の数が４本以上になる場合には、中央に一本又は複数本の金属線が配置されることはあるが、本発明では中央に配置される前記金属線は形状維持機能を有している必要はない。すなわち、前記金属撚り線の中心に前記金属線その他形状維持のため部材を有しない構成としてある。
請求項２に記載するように、前記金属撚り線のピッチは基準撚りピッチよりも小さいものであるのが好ましく、請求項３に記載するように、前記金属撚り線が３本の前記金属線から形成される場合に、前記ピッチを前記金属撚り線の直径の３〜４倍とするのがよい。請求項４に記載するように、前記複数本の金属線の少なくとも一部がチタン又はチタン合金であってもよい。
In order to solve the above problems, the temple for spectacles according to claim 1 is formed of a metal stranded wire formed by twisting a plurality of metal wires, and in the temple for spectacles having a curved ear hook portion, the metal A gap between the metal wires formed by plastically deforming the metal wires by applying a pressing force from the periphery of the stranded wire, and a curved portion in which the metal stranded wire is deformed into a curved shape in the gap portion Have.
In the present invention, the gaps formed between the metal wires make it easy to deform the metal stranded wire into a curved shape, and another shape maintaining member such as a core material is not necessary. Of course, when the number of metal wires constituting the metal stranded wire is four or more, one or a plurality of metal wires may be arranged at the center, but in the present invention, the metal wires are arranged at the center. The metal wire does not have to have a shape maintaining function. That is, it is set as the structure which does not have a member for the said metal wire or other shape maintenance in the center of the said metal stranded wire.
As described in claim 2, the pitch of the metal stranded wire is preferably smaller than the reference twist pitch, and as described in claim 3, the metal stranded wire comprises three metal wires. When formed, the pitch may be 3 to 4 times the diameter of the metal stranded wire. As described in claim 4, at least a part of the plurality of metal wires may be titanium or a titanium alloy.
上記構成の本発明の眼鏡用テンプルは、以下の方法によって製造することができる。
請求項５に記載の製造方法は、複数本の金属線を撚り合わせてなる金属撚り線から形成され、湾曲状の耳掛け部分を有する眼鏡用テンプルの製造方法であって、前記金属撚り線の周囲から押圧力を付与し、前記金属線間に隙間が形成されるように前記金属撚り線を塑性変形させる塑性変形工程と、撚りがほどけないように前記金属撚り線の端末を処理する端末処理工程と、前記隙間部分で前記金属撚り線を湾曲状に変形させることで、所定長さの前記金属撚り線を湾曲加工する湾曲加工工程とを有する。前記端末処理工程と前記湾曲加工工程とはその工程の前後が逆になってもよい。本発明では、前記金属撚り線として前記金属線その他形状維持のため部材を有しないものを用いることができる。
The temple for spectacles of this invention of the said structure can be manufactured by the following methods.
The manufacturing method according to claim 5 is a manufacturing method of a temple for spectacles which is formed of a metal stranded wire formed by twisting a plurality of metal wires and has a curved ear hook portion, A plastic deformation step of applying a pressing force from the periphery and plastically deforming the metal stranded wire so that a gap is formed between the metal wires, and an end treatment of processing the end of the metal stranded wire so that the twist is not released And a curving step of curving the metal stranded wire having a predetermined length by deforming the metal stranded wire in a curved shape in the gap portion . The front end processing step and the bending processing step may be reversed before and after the processing. In the present invention, as the metal stranded wire, it is possible to use the metal wire or the like which does not have a member for shape maintenance.
押圧力の付与は、請求項６に記載するように複数回に分けてもよいし、前記金属撚り線のピッチは、請求項７に記載するように基準撚りピッチよりも小さくてもよい。また、前記金属撚り線が３本の前記金属線から形成される場合は、請求項８に記載するように、前記ピッチを前記金属撚り線の直径の３〜４倍とするのが好ましい。
また、本発明では、請求項９に記載するように、前記金属撚り線の塑性変形率を調整することによって、前記湾曲の曲率半径を大小調整することができる。なお、前記押圧力の付与は、請求項１０に記載するようにスウェージング加工によって行うようにしてもよい。
The application of the pressing force may be divided into a plurality of times as described in claim 6, and the pitch of the metal stranded wire may be smaller than the reference twist pitch as described in claim 7 . When the metal stranded wire is formed of three metal wires, as described in claim 8, it is preferable to make the pitch 3 to 4 times the diameter of the metal stranded wire.
In the present invention, as described in claim 9 , the curvature radius of the curve can be adjusted in size by adjusting the plastic deformation rate of the metal stranded wire. The application of the pressing force may be performed by swaging as described in claim 10 .
