【考案の詳細な説明】
本考案は、めがね用レンズを金属製前フレームに取り付
ける構造に関する。[Detailed Description of the Invention] The present invention relates to a structure for attaching spectacle lenses to a metal front frame.
従来では、レンズを前フレームに固定するに当って、レ
ンズに形成された取り付は孔に金続製ボルトを貫通し、
このボルトを金続製前フレームに刻設された内ねしに螺
着している。Conventionally, when fixing a lens to the front frame, a bolt made of gold was passed through the hole in the mounting hole formed on the lens.
This bolt is screwed into the inner thread carved into the front frame made by Kintsugi.
このような先行技術では、金属製前フレームに外力が作
用したとき、前フレームは比較的変形しやすく、これに
対して、レンズは剛性であり、またレンズと金属製ボル
トとが接触することによって、レンズの取り付は孔から
ひびが入ったり、割れたりする。In such prior art, when an external force is applied to the metal front frame, the front frame is relatively easily deformed, whereas the lens is rigid, and the contact between the lens and the metal bolt deforms the front frame. , the lens attachment may crack or break from the hole.
したがって本考案は、外力によってレンズが損傷しない
ようにしためがね用レンズの取り付は構造を提供するこ
とである。Therefore, the object of the present invention is to provide a structure for attaching eyeglass lenses to prevent the lenses from being damaged by external forces.
第１図は本考案の一実施例のめがねの斜射図であり、第
２図は第１図の切断面線ＩＩ −ＩＩから見た簡略化し
た断面図である。FIG. 1 is a perspective view of eyeglasses according to an embodiment of the present invention, and FIG. 2 is a simplified sectional view taken along section line II--II in FIG. 1.
レンズ１は、ガラスまたは合成樹脂製である。The lens 1 is made of glass or synthetic resin.
このレンズ１の外周部には、取り付は孔２が形成される
。A mounting hole 2 is formed in the outer periphery of this lens 1.
レンズ１が取り付けられる前フレーム３は、鉄またはア
ルミニウムなどの金属製である。The front frame 3 to which the lens 1 is attached is made of metal such as iron or aluminum.
この前フレーム３には、取り付は孔２に対応して、取り
付は孔４が形成される。The front frame 3 is provided with mounting holes 4 corresponding to the mounting holes 2.
レンズ１と前フレーム３との間には、合成樹脂製のワッ
シャ５が介在される。A synthetic resin washer 5 is interposed between the lens 1 and the front frame 3.
レンズ１と前フレーム３とワッシャ５とは、これらを貫
通する合成樹脂製のリベット状止め具６によって固定さ
れる。The lens 1, front frame 3, and washer 5 are fixed by a rivet-like stopper 6 made of synthetic resin that passes through them.
前フレーム３には、耳に掛けるための側フレーム１０が
ヒンジによって装着される。A side frame 10 for hanging on the ear is attached to the front frame 3 by a hinge.
止め具６によってレンズ１を前フレーム３に取り付ける
に当っては、第３図に示す形状を有する止め具６を準備
する。When attaching the lens 1 to the front frame 3 using the fastener 6, the fastener 6 having the shape shown in FIG. 3 is prepared.
この止め具６は、頭部７と軸部８とを有する。This stopper 6 has a head 7 and a shaft 8.
軸部８をレンズ１の取り付け（Ｌ２、ワッシャ５、およ
び前フレーム３の取り付は孔４に貫通する。The shaft portion 8 passes through the hole 4 for attaching the lens 1 (L2, the washer 5, and the front frame 3).
そこで、前フレーム３外方に取り付は孔４から突出して
いる止め具６の軸部８の端部を熱溶融する。Therefore, when attaching the front frame 3 to the outside, the end portion of the shaft portion 8 of the stopper 6 protruding from the hole 4 is thermally melted.
これによって軸部８の端部には取り付は孔４よりも大径
の抜は止め部９が形成される。As a result, a removal stopper 9 having a diameter larger than that of the mounting hole 4 is formed at the end of the shaft portion 8 .
止め具６およびリベット５はポリアミド系合成樹脂であ
ってもよい。The stopper 6 and the rivet 5 may be made of polyamide synthetic resin.
これらの合成樹脂は、比較的硬く、摩耗しにくく、また
加工しやすいという点で優れている。These synthetic resins are superior in that they are relatively hard, resistant to wear, and easy to process.
以上のように本考案によれば、合成樹脂契止め具がレン

ムに固着されるので、前述の先行技術のようにレンズと
金属製ねじとが接触することが本考案では無く、したが
って外力によってレンズの取り付は孔付近からひびが入
ったり、割れたりすることが防がれる。As described above, according to the present invention, the synthetic resin fastener passes through the lens and the metal front frame, and the lens is fixed to the front frame. According to the present invention, the lenses are not in contact with each other, so that the lens attachment is prevented from cracking or breaking near the holes due to external force.
またレンズと前フレームとの間に合成樹脂製ワッシャが
介在されるので、レンズとフレームとが直接に接触する
ことがなく、ワッシャの弾性によって、またレンズと前
フレームとの相互の滑りが向上されて、レンズの損傷が
防がれる。In addition, since a synthetic resin washer is interposed between the lens and the front frame, the lens and frame do not come into direct contact, and the elasticity of the washer improves the mutual sliding between the lens and the front frame. This will prevent damage to the lens.
第１図は本考案の一実施例の斜視図、第２図は第１図の
切断面線ＩＩ −ＩＩから見た簡略化した断面図、第３
図は予め準備された止め具６の斜視図である。FIG. 1 is a perspective view of one embodiment of the present invention, FIG. 2 is a simplified cross-sectional view taken from section line II-II in FIG. 1, and FIG.
The figure is a perspective view of a fastener 6 prepared in advance.
