Description of the invention 6) [Technical Field to which the Invention belongs] The present invention relates to a hinge for eyeglasses, which can make the hinge part of the constituent components of the eyeglasses not to be hooked with metal The side is a spectacle hinge with a structure that expands from the normal side to the same side. [Conventional Technology] Conventionally, there is a well-known spring-attached hinge system for spectacles that allows the metal hooks of the spectacles to elastically adhere to the side portions of the face of the person carrying the spectacles. For example, in Japanese Patent Application Laid-Open No. 6-6 4 2 64, it is described that the hinge part and the outer surface of the metal hook are on the same side, and when the metal hook is expanded outward, the top of the metal hook and the hinge part is used. The connected part is a fulcrum and the metal hook is rotated instead of the hinge shaft as the fulcrum. In this configuration, when the metal hook is expanded outwardly from the hinge portion, the hinge device constituting the aforementioned hinge is configured to slide the metal hook. In addition, there is also a hinge for spectacles that allows the metal hooks of the spectacles to elastically fit to the side portions of the face of the spectacles, as described above. The simpler structure is, for example, Japanese Patent Application Laid-Open No. 6 4- Japanese Patent No. 3 820 describes that a flat portion of a hinge portion is rotated through a lateral groove provided at an opening on the outer side of the metal hook, so that the metal hook can be turned inward and outward. [Problems to be Solved by the Invention] However, in the aforementioned conventional hinges, the structure described in Japanese Patent Application Laid-Open No. 6-64264 is required to ensure that the hinge can be reliably slid against the metal hook. Dovetail groove processing is adopted, and the size of this paper is applicable to China National Standard (CNS) A4 (210 X 297 mm) ---- I ----- II,.

Description of the invention) The cost of manufacturing on the ground also becomes higher. Furthermore, in the narrow part of the small spectacle parts, it is necessary to perform a dovetail groove or a complicated process. The mechanical strength of the entire spectacles and the hinge part becomes a problem. In addition, the structure described in Japanese Patent Application Laid-Open No. 6 4-3 8 2 0 is an advantage because of its simpler structure. However, the lateral grooves of the hinge portion can be seen in appearance, and the design of the glasses is lacking. One of the body sensations that are valued; moreover, when the metal hook is not folded when not in use, the flat portion of the hinge portion protrudes, which also becomes a disadvantage in the design of glasses. The present invention is made to solve the above-mentioned problems, and an object thereof is to provide a simple structure, but as an irreconcilable part of the appearance of the glasses, it can create a sense of unity and high-quality. It is usually a hinged spectacle of a structure that can be opened to the outside in a smooth state. [Means to Solve the Problem] In order to achieve the above-mentioned object, the present invention is a hinge provided on a hinge portion of a pair of glasses and a metal hook, and includes an outer hinge body, which is inserted into a part of the outer hinge body and penetrates through the aforementioned outer body. The hinge body and the middle hinge body, and the hinges supporting the outer hinge body and the middle hinge body so that the rotating shaft body which can be relatively rotated are characterized in that between the outer hinge body and the middle hinge body A flat body with a slit portion formed in a part thereof to form two elastic arm portions is inserted, so that one of the elastic arm portions is fastened to a portion of the outer hinge body, and the other is fastened to a portion of the middle hinge body. When the metal hook expands to the outside of the hinge portion, it narrows the slit and applies the Chinese National Standard (CNS) A4 specification (210 x 297 mm) to the previous paper size.
