Abstract: Disclosed is an improved structure for coupling some selected parts of a pair of glasses, particularly for fixing a lens to an associated rim and at the same time, the rim to the joint piece, to which one or the other temple is hinged. The rim has a loop hole at its outer side, dividing the rim circumference into upper and lower rim halves. The rim has two broach sections fixed to the opposite ends of the upper and lower rim halves, and the joint piece has a hollow coupler member to permit the broach sections to be press-fitted therein, thereby holding the lens inside the rim. Two catch pins are fixed to the inner sides of the adjoining rims. These catch pins are inserted into the lateral holes of the opposite ends of the bridge, thus detachably connecting the bridge to the adjoining rims.

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.
