Abstract

The present invention relates to a connection structure for thin-plate eyeglass frames and temples, in which: eyeglass frames and temples pressed by wire cutting or by a press on a thin steel plate are simply assembled without being coupled by a screw; there is a function of elastically maintaining a folded or unfolded state by a repellent force such as a spring hinge when the temples are folded or unfolded; there are no gaps between the temples such that the temples are fixed without moving in an axial direction or in either an upper or lower direction; and lenses are easily mounted during assembling. The purpose of the present invention is to solve prior problems, and thus the invention provides a connection structure for a thin-plate glasses frame and temples, in which: a glasses frame and temples pressed by wire cutting or by a press on a thin steel plate are simply assembled without being coupled by a screw; a folded or unfolded state is elastically maintained by a repellent force such as a spring hinge when the temples are folded or unfolded; the temples are fixed without moving in an axial direction or in either upper or lower directions since there are no gaps between the temples; and upper and lower connecting portions of the temples are detachably divided such that lenses are easily mounted when the lenses are assembled. To accomplish said purpose of the present invention, the invention is formed as follows: a side portion of an eyeglass frame (10) formed as a thin plate is divided into two upper and lower sides and the two sides are curved to the back, respectively, so that an upper connection plate (20) and a lower connection plate (30) are comprised to be detached from each other; hooks (21, 31), which are respectively widened in an inner side direction as going toward the back and having rear ends that are rapidly curved again in an outer side direction, are formed in the middle of the upper connection plate (20) and the lower connection plate (30) by partial cutting; guide protrusions (22, 32) are inwardly protruded on the intermediate upper and lower parts of the upper and lower connection plates (20, 30) remaining after the hooks (21, 31) have been separated; a fore-end of a temple (40) formed as a thin plate is curved at a certain angle such that the fore-end is inwardly inclined to form through holes (41) on the upper and lower parts of said inwardly curved portion, wherein fore-ends of the hooks (21, 31) of the upper connection plate (20) and the lower connection plate (30) are penetrated and inserted into the through holes, respectively; slide protrusions (42) are protruded to be curved in a front outer direction on upper, intermediate, and lower parts of the end of the temple (40) having the through holes (41), so that the slide protrusions elastically come in contact with the guide protrusions (22, 32) of the upper connection plate (20) and the lower connection plate (30); and an interval between stopping portions (43) and the through holes (41) at the end of the temple (40), which comes in contact with the inner side of the curved portions of the hooks (21, 31), is narrowed in width to allow rotation therein.
