发明名称 Method for making a spectacle frame
摘要 A method for manufacturing a spectacle frame includes molding a frame having two extensions formed in the side portions. The extensions each has a groove for receiving a spring and a ball and each has a lateral channel intersecting the groove. A pair of legs each has one end pivotally coupled to the free end portion of the extensions by a pin for allowing the legs to be engaged with the ball. The legs are not required to be excavated. In addition, the spring members can be easily assembled in the extensions of the spectacle frame.
