Abstract

As shown in "Reference Drawing 1 Representing the Usage State", this article can separate the front frame left and right by releasing the joining by magnets at the joining part in the center of the bridge of the front frame. By attaching and detaching the magnetic attachment at the joining part of the bridge part, the user can wear the glasses or use them by hanging them around the neck. When rejoining after releasing the magnetic attachment of the bridge part, as shown in "Reference Drawing 1 Representing the Usage State", insert the fitting convex part into the fitting groove part to fit the joining surfaces and magnetically attach the magnets on the joining surfaces to connect the front frame. Also, "Reference Drawing 2 Representing the Usage State" is a partial enlargement of the "Cross-sectional View of Part A-A", showing the state of the left side surface viewed from the inside with the magnetic attachment released at the bridge joining part. As shown in "Reference Drawing 2 Representing the Usage State", the temple base end part of this article has a nested structure and functions as a length adjustment mechanism for adjusting the length of the temple. In the nested structure of the length adjustment mechanism, the inner part (the nested part) of the nested structure slides back and forth inside the outer part of the nested structure. As shown in "Reference Drawing 2 Representing the Usage State", the "outer part" of the nested structure is provided with a connecting hole part where five holes are connected horizontally, and the inner part (the nested part) of the nested structure is provided with a protrusion "stopper". By locking the stopper into each hole of the connecting hole part, the length of the temple is adjusted step by step.
