In addition, the height of one of the front and rear side walls of the fitting groove is set to a height that allows the eyeglass frame to ride over the rim by elastic deformation.

In this decorative rim, if the whole or a part is elastically deformed so that the side wall of the fitting groove goes over the rim of the spectacle frame, the fitting groove can be easily fitted to the outer periphery of the rim of the spectacle frame. Can be mounted on the rim of the spectacle frame. Also, if the operation is performed in reverse, it can be easily removed from the spectacle frame. Therefore, the spectacle frame can be easily replaced by the spectacle wearer, and the user can enjoy a change in the design of the spectacle frame depending on time and case.

According to a second aspect of the present invention, in the decorative rim for an eyeglass frame according to the first aspect, the height of the side wall on the rear side of the fitting groove is set to a height at which the rim can ride over the rim of the eyeglass frame by elastic deformation. A notch for yoke is formed on a part of the front side wall to avoid interference with the yoke of the eyeglass frame, and a notch for bridge is formed on a part of the rear side wall to avoid interference with the bridge of the eyeglass frame. It is characterized by having.

The decorative rim can be mounted on the rim of the spectacle frame from the front side by setting the height of the fitting groove. In that case, the eyeglasses of the eyeglass frame enter the notch for the eyeglasses, and the bridge of the eyeglass frame enters the notch for the bridge, so that the eyeglasses are securely housed in the eyeglass frame without interfering with each part.

The decorative rim for a spectacle frame according to the third aspect of the present invention is the decorative rim for an eyeglass frame according to the first or second aspect, on the inner periphery of the front side wall of the fitting groove, on the front surface of the main lens fitted to the rim of the spectacle frame. The sub-lens located is fitted.

This decorative rim is a main lens (eyeglass lens)
Since it has a sub lens located in front of the camera, if you use a dark color lens for light shielding as a sub lens,
A light-shielding function can be easily provided.

According to a fourth aspect of the present invention, the decorative rim for an eyeglass frame is formed as a ring-shaped body having a fitting groove on its inner periphery to be detachably fitted to an outer periphery of the rim of the eyeglass frame, and the ring-shaped body is provided. It is characterized in that the body is cut in the circumferential direction with a notch for the yoke which avoids interference with the yoke of the spectacle frame.

Since the decorative rim has a ring cut out with a cutout for the yoke, it can be easily mounted on the rim of the spectacle frame simply by opening it using elasticity. In addition, the ring of the decorative rim is cut off with the cutout for the yoke, so that the appearance is not impaired.

According to a fifth aspect of the present invention, there is provided a method of mounting the decorative rim for an eyeglass frame on the eyeglass frame according to the second aspect, wherein the decorative rim is inserted into a temple of the eyeglass frame with the rear surface facing forward, and the decoration is performed.

The bridge notch 3 is provided on the rear surface. However, in some frames, for example, both the bridge and the yoke are brazed to embrace the rim from the front, and many of the frames are also braided to embrace the rim from the rear. . Therefore, in that case, the cutouts of the decorative rim are arranged on the front side or the rear side of both the flap portion and the bridge portion. In that case, FIG.
Since it is impossible to adopt the mounting method as shown in (1), the frame is simply fitted from the rear surface to the front surface or from the front surface to the rear surface. As described above, the location of the cutout provided on the decorative rim varies depending on the direction in which the bridge or the yoke is attached to the rim. In addition, the mounting direction of the decorative rim also changes according to the notched direction.

In the above embodiment, acetate is used as the material of the decorative rim, but other materials can of course be used. For example, tortoiseshell, ABS resin,
In addition to epoxy resin, celluloid, propionate, nylon, carbon, PAN-based high-strength type carbon fiber, carbon fiber reinforced resin (Carbomax), silicon carbide (whisker), silicon rubber, elastomer, and the like can be used.
