Abstract: A hinge and joint for a pair of eyeglasses is disclosed. A split frame has upper and lower rim end pieces that bend and extend rearwardly. A vertically-extending hollow shaft is provided on the end of a temple. A spring or springs are positioned laterally between the rim end pieces and the shaft, such that the shaft bears against the spring or springs. A U-shaped housing fits over the exterior top, bottom, and side of the joint and has a pair of aligned slots in top and bottom flanges. A pin is placed through the aligned slots in the housing and the shaft of the temple. Lateral force provided by the spring or springs biases the joint away from the aligned position, and that force, in combination with upper and lower shoulders on the pin, keep the joint and hinge together.

Abstract: A rim locker for spectacle frame comprises a first portion and a second portion which are connected to two edges of lens rim in cut-off position respectively. The second portion has a screw hole for inserting a screw and the first portion is having thread to let the screw in for fastening the lens rim. The screw further has a stopping cap and the first portion further has a cylinder housing for hiding and moving the stopping cap, so that when the rim-locker is opening, the stopping cap will moving along the track of the housing, and stop at the end to prevent the screw slip off from the rim-locker and protect the screw threads not strip off easily.

Abstract: There is provided a spectacle frame comprising: a front for holding therein two lenses; the front having front end pieces extending rearward at each end thereof, each front end piece having an upper portion and a lower portion; and one of the upper portion and the lower portion having a geometric projection for engagement in and disengagement from a corresponding sized and shaped geometric opening in the other of the upper portion and the lower portion, the engagement and disengagement being by lateral movement only. A clip for engagement with front end pieces of a spectacle frame is also disclosed.

Abstract: A front part includes an upper frame and a lower frame, which are formed by bending a wire material, in which the upper frame and the lower frame each have rim pieces formed at both ends of a connecting part, which are retained to each other at the center, and in which wraparound endpieces provided on the outside of the upper and lower rim pieces are connected to each other to be assembled. The upper and lower frames have the wraparound endpieces in which rings are formed on the outside thereof, and temple has also rings formed at ends thereof. The rings are assembled, a shaft is fitted in shaft holes of the rings and is tightened with a screw.

Abstract: In spectacle frames having exchangeable edge bars (10) of the type that by one end is fastened by an engagement with the bridge (2) the edge bar is retained at its far end by a fixing member (16) in the form of a pin or rivet cooperating with a hole, said fixing member being subject to a snap lock effect. The edge bar can thereby be instantly replaced without needing any tools.

Abstract: To avoid excessive stressing of lenses and still facilitate the attaching and removing of the lens to the rim, a pair of eyeglasses has an improved rim lock member. The rim lock member has a two-parallel wire arrangement and a metal piece slidably movable thereon. The opposite ends of the loop hole of each rim are connected to the two parallel wire ends, and the space of the loop hole can be controlled by moving the metal piece on the two-parallel wire arrangement. Specifically the loop hole of each rim can be reduced by moving the metal piece toward the rim on the two-parallel wire arrangement until the circumferential length of time rim is shortened to wind tightly around the lens, thereby holding the lens fixedly. The bridge of the front of a pair of rimless eyeglasses has a similar parallel wire-and-metal assembly structure.
