JPS5924009Y2 - metal eyeglass frames - Google Patents

Description

[Detailed explanation of the invention] If the lens frame of the glasses is made thin so as not to be an eyesore, since the frame is thin, attachment of the butterfly legs by brazing is weak, and attachment of the joint by brazing is also weak.

Also, when opening and closing the temple, the frame tends to turn inside out at the joint, making it easy for the lens to come off.

In addition, in cases where the left and right lens frames are connected by a bridge like this, the outer end of the bridge is extended close to the joint and brazed to the lens frame, so when opening and closing the temple, the joint part Although there is little tendency for the frame to turn over, the joint and butterfly legs are attached to a narrow lens frame, so the attachment is weak.

The present invention aims to provide a metal eyeglass frame with a thin lens frame that does not have such drawbacks.

In the present invention, an outer edge 3 with grooves 2 for fitting the frame is placed on the upper part of a thin metal lens frame 1 and brazed to the top, and the tips of butterfly legs 4 are attached to the inner lower end of the outer edge 3. The present invention relates to a metal eyeglass frame characterized in that a piece of a joint 5 is brazed to the outer lower end, and each end of a crest 6 is brazed to the left and right outer edges 3, 3.

According to the present invention, since the upper part of the frame is made by fitting the thin lens frame 1 into the groove 2 on the lower surface of the outer edge 3 and brazing it, this part becomes a double frame and is not only strong but also Since the joint 5 and the butterfly leg 4 are brazed, the installation is strong.

Further, each end of the crest 6 is fixed to the left and right outer edges 3, 3 by brazing, and even if the left and right outer edges 3, 3 and the ridge 6 are integrated, they are strong and will not bend or twist.

A joint 5 is attached to the end of this integrally strong outer edge 3, 3.
Since the lenses are brazed, even when the temples are opened and closed, their movement does not affect the thin lens frame 1, the lens frame does not turn over, and the lens can be mounted securely.

Furthermore, since most of the frame 1 is thin except for the upper part, the frame not only does not become an eyesore, but also has excellent effects such as good appearance because the upper part of the frame is thicker and the lower part is thinner and the thickness varies.
