Claims

[Claims for Utility Model Registration] (1) A spectacle frame in which the lens frame is divided into an upper frame having a bridge in the center and a lower frame also having a bridge, which is attached to the bridge of the upper frame and the lower frame. The joint butterfly has a structure in which supporting pieces are provided at both ends of the connecting piece, and the connecting piece is provided with fitting grooves into which the bridge parts of the upper frame and the lower frame fit, and on both sides of the supporting piece. A U-shaped clamp having a pair of upper and lower engaging pieces, which forms a support groove into which the inner side of the lower frame is fitted, is fitted to the outside of the upper and lower walls of the fitting groove, and the clamp is engaged. An eyeglass frame characterized in that the inner surface of the joint piece is an inclined surface that matches the downwardly inclined surfaces provided on the outside of the upper and lower walls. (2) Both ends of the lens frame are divided into upper and lower parts, and a pair of clamping pieces facing each other is provided in the divided parts, and the clamping pieces are inserted into the side surfaces of a coupling device that fixes the clamping pieces. A fastening piece inserted into the insertion hole and a connecting tool are connected with a pin, and either the back of the connecting tool or the tip of the temple that is rotatably attached to the connecting tool is provided. is provided with a pair of upper and lower mounting pieces, and the other is formed with an insertion piece that is inserted between the mounting pieces, and a spherical convex portion is formed on either the inner surface of the mounting piece or the upper or lower surface of the insertion piece. and a locking recess that engages with the protrusion on the other side.
