HINGE COUPLING DEVICE AND HINGE COUPLING STRUCTURE FOR SPECTACLE FRAME

摘要

PURPOSE: A hinge connecting device for an eyeglass frame is provided to control the movement between hinge pieces by adjusting the connecting length between a fixing piece and a fixing cap by rotating the fixing piece according to the movement of the hinge piece formed in a leg and a front. CONSTITUTION: Hinge connecting devices (1,1') for an eyeglass frame hinge legs (120) to both ends of a front (110) by penetrating a gap between the hinge pieces (111,112) of the front and the hinge piece (121) of a leg. A pair of hinge pieces comprises an upper hinge piece (111) and a lower hinge piece (112) and is vertically separated from each other at the end of the front. A single hinge piece (121) which is layered on the hinge pieces of the front is protruding from a gap between the upper and lower hinge pieces of the front. Hinge holes (111a,112a,121a) are vertically connected to each other in the hinge pieces of the front and the leg. A hinge connecting device penetrates the hinge holes of vertically laminated hinge pieces (111,112,121) to hinge the same.
