Hinge device for glasses

Abstract

This article is a hinge device provided in the temple of glasses and used to open and close the temple. As shown in the reference perspective view and the exploded reference perspective view, this article is composed of a shaft member that serves as an axis when opening and closing the temple, a bolt that fixes this article to the temple of the glasses frame by screwing a screw portion into the screw hole of this shaft member and tightening it, a lower washer interposed between the shaft head and the temple, and an upper washer interposed between the bolt head and the temple. And, as shown in the front view and the right side view, the peripheral surface is formed as a gently continuous inclined surface from the bolt head toward the upper washer and from the shaft head toward the lower washer, and this part presents an appearance like Mount Fuji.
