【考案の詳細な説明】 本考案は眼鏡に関する。[Detailed explanation of the idea] The present invention relates to eyeglasses.
従来、眼鏡のレンズ枠にはセル枠、ナイロン繊
維枠あるいはワイヤー枠等があるが、夫々個有の
欠点を有している。 Conventionally, lens frames for eyeglasses include cell frames, nylon fiber frames, wire frames, etc., but each has its own drawbacks.
セル枠は、枠形状を成形するために切削工程が
必要なため製作上能率が悪い上、レンズの嵌め込
みの際には熱膨張させる必要があるのでレンズ取
り付け作業の能率も悪いという欠点がある。 Cell frames have disadvantages in that they require a cutting process to form the frame shape, which is inefficient in terms of production, and they also require thermal expansion when fitting lenses, which makes lens attachment work inefficient.
ナイロン繊維枠は製作やレンズ取り付けの点で
は能率が良いが、使用中に緩みが生じレンズがが
たつき易いという欠点がある。 Although nylon fiber frames are efficient in terms of manufacturing and lens attachment, they have the disadvantage that they tend to loosen and the lenses tend to wobble during use.
またワイヤー枠は、レンズの周囲にこのワイヤ
ーを巻いて締め付ける際にレンズに過大な力がか
かつてヒビ割れし易という欠点がある。 Another disadvantage of wire frames is that when the wire is wrapped around the lens and tightened, excessive force is applied to the lens, causing it to easily crack.
本考案は、従来の上記各種のレンズ枠の欠点に
鑑みてなしたもので、レンズ枠自体の製作が容易
かつ安価で、レンズ取り付け作業も能率的にして
かつレンズにひび割れが生ずることもなく、さら
に使用中においてもレンズが安定する新規なレン
ズ枠を用いた眼鏡を提供するものである。 The present invention was created in view of the drawbacks of the various conventional lens frames mentioned above.The lens frame itself is easy and inexpensive to manufacture, the lens installation work is efficient, and the lens does not crack. Furthermore, the present invention provides eyeglasses using a novel lens frame in which the lenses are stable even during use.
以下に、図示の実施例について本考案を具体的

嵌合する周溝を設ければよい。 When fitting the lens 1 into the lens frame 2, adjust the frame diameter of the lens frame 2 using the slit 2c.
Enlarge as shown in Figure 3A. By enlarging in this way, the lens 1 can be fitted into the lens frame 2 very easily, as shown in FIG. 3B. The fitting structure between the lens 1 and the lens frame 2 can be designed as appropriate. For example, as shown in FIG. A circumferential groove into which the protrusion 1aa fits may be provided on the inner circumferential surface.
上記の如く、レンズ１をレンズ枠２に嵌め込ん

Note that this cover 4 has a screw insertion hole 4 corresponding to the through hole 2d of the protrusion 2b.
It has a.

ワイヤー枠の場合に生じたレンズのヒビ割れの問
題は生じない。 As is clear from the specific description of the above embodiments,
According to the present invention, since the lens frame is manufactured by injection molding, manufacturing is efficient and the dimensional accuracy is good.Also, since the lens frame is formed with a protrusion having a slit, this slit can be used. As a result, the diameter of the lens frame can be easily increased, and thereby the lens can be easily fitted into the lens frame. In addition, the protrusion with the slit is covered with a cover to prevent magnification and then connected with the wafer, which prevents the lens frame from inadvertently expanding when using glasses, and the lens Stable within the frame. moreover,
Since this lens frame is made of soft resin as described above, it easily fits into the lens and does not cause the problem of cracking of the lens that occurs in the case of conventional wire frames.
