【発明の詳細な説明】
本発明は、めがねフレームの製造に際して左右のレンズ
枠やそれらの連結金具、鼻当て等のフレーム用部材を互
いに接合するための接合方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joining method for joining frame members such as left and right lens frames, their connecting fittings, and nose pads to each other during the manufacture of eyeglass frames.
近年、めがねフレームとして、装飾性に勝れ且つ軽量で
強度の大きい金属製のものが多く使用されている。金属
素材としてチタンを使用すれば、それを一段と軽量且つ
高強度なものに形成することができる。In recent years, many frames made of metal have been used as eyeglass frames because they are highly decorative, lightweight, and strong. If titanium is used as the metal material, it can be made even lighter and stronger.
ところが、金属チタンによってめがねフレームを形成す

ことから、レンズ枠やその連結金具、鼻当て等のめかね
フレーム用部材の接合が困難となり、通常の接合方法で
はめがねとして必要十分な接合強度を得ることはできな
い。However, when forming eyeglass frames from titanium metal, it is generally very difficult to join the titanium metal materials, making it difficult to join eyeglass frame components such as lens frames, their connecting fittings, and nose pads. With this joining method, it is not possible to obtain sufficient joining strength for eyeglasses.

非常に小さく、接合部の大部分には隙間が形成されるこ
とになるため、部材にねじれや曲りが生じ易い。That is, in the case of brazing, although there is an advantage that the joint area can be increased, the joint strength cannot be increased very much, and the joint part is likely to peel off due to the action of external force. In addition, although spot welding can achieve greater joint strength than brazing, the joint area is very small and gaps are formed in most of the joints, so it is difficult to Twisting and bending are likely to occur.
而して、上述したような問題は、めがねフレームを金属
チタンを用いて形成した場合に特に顕著であるが、その
他の金属素材で形成した場合にも同様に発生する。The above-mentioned problems are particularly noticeable when glasses frames are made of titanium metal, but they also occur when glasses frames are made of other metal materials.

ものである。The present invention aims to provide a joining method that can easily join metal eyeglass frame members with extremely high strength, and the eyeglass frame members to be joined to each other are temporarily joined by spot welding. , the temporarily joined members are brazed around the welding points.
而して、本発明の接合方法によれば、接合部を点溶接で

長所が結合して非常に大きな接合強度を得ることができ
る。According to the joining method of the present invention, after the joint is temporarily joined by spot welding, the area around the welding point is brazed, so that the shortcoming of spot welding, which is the small joint area, can be avoided by brazing. On the other hand, the drawback of low joint strength is compensated for by spot welding, and the advantages of both can be combined to obtain a very high joint strength.
以下、本発明の接合方法を、めがねフレーム用部材とし
てのレンズ枠と鼻当てとを接合する場合について説明す
る。Hereinafter, the bonding method of the present invention will be described with respect to the case of bonding a lens frame and a nose pad as a member for an eyeglass frame.
第１図において、１はレンズを取付けるためのレンズ枠
、２は鼻当てを示しており、これらのレンズ枠及び鼻当
てはいずれも金属チタンを素材として形成されている。In FIG. 1, numeral 1 indicates a lens frame for attaching a lens, and numeral 2 indicates a nose pad, both of which are made of titanium metal.

、溶接点４の廻りに微小な間隙５が形成されている。” - If the nose pad 2 can be placed on the lens frame 1, the second
As shown in the figure, when attaching the nose pad 2 (the Q frame 3 is brought into contact with the lens frame 1 and the joints are temporarily joined by spot welding. This spot welding can be performed by a well-known method such as electric resistance welding. As a result, a small gap 5 is formed around the welding point 4 in the temporarily joined joint.
次に、仮接合した上記接合部を、溶接点４を中心にして
広い面積でろう（ｌけする。このろう付けにより、上記
間隙５はろう材θで埋められ、接合部全体が強固に接合
されることになる。即ち、必要な接合強度は主として点
溶接で確保され、これにろう（ｑけによる強度が加わる
ため全体としての接合強度は非常に大きくなり、また、
点溶接における接合面積が小さいという欠点はろう付け
で補償され、十分な接合面積が確保されるため、接合部
における両部材のねじれや曲り等が生じにくい。Next, the temporarily joined joint is brazed over a wide area around the welding point 4. Through this brazing, the gap 5 is filled with the brazing material θ, and the entire joint is firmly joined. In other words, the necessary joint strength is mainly secured by spot welding, and since the strength due to soldering is added to this, the overall joint strength becomes very large.
The drawback of spot welding having a small joint area is compensated for by brazing, and since a sufficient joint area is ensured, twisting or bending of both members at the joint is less likely to occur.

金具８との接合等にも適用し得ることはいうまでもなく

る場合にも有効に適用することができる。It should be noted that the bonding method described above can also be applied to the bonding of the left and right lens frames 1 and the connecting frame 7 that connects them, the bonding of the lens frame 1 and the mounting bracket 8, etc. Needless to say, the present invention can also be effectively applied to cases where each of the above members is made of metal other than titanium.
