Description

  The present invention relates to an attachment / detachment structure capable of easily attaching / detaching auxiliary glasses such as dustproof glasses, a working safety cover, or sunglasses to / from ordinary glasses.

  Special glasses such as dust-proof glasses and sunglasses are used as appropriate depending on the environment and working conditions. However, a person wearing glasses cannot originally wear normal glasses and special glasses. And if you wear special glasses, you cannot get normal vision. In order to solve this, special glasses such as prescription sunglasses may be used, but in this case, special glasses with prescription need to be specially ordered and become very expensive. There is a drawback.

In addition, as shown in Patent Documents 1 and 2, special glasses are used as auxiliary glasses that do not hang, and the auxiliary glasses can be attached to and detached from the normal glasses body, so that people wearing glasses can also feel like dustproof glasses. Special glasses are used freely. Patent Document 1 discloses the idea of attaching and detaching the protective cover to the spectacle body and using it as dust-proof spectacles. However, in this structure, the protective cover and the spectacles are fixed with a string-like body, so that they can be easily attached and detached. I can't. Moreover, although the idea of configuring the string-like body with an elastic member such as rubber has been disclosed, in this case, there is a drawback that the auxiliary glasses cannot always be firmly fixed. Further, Patent Document 2 discloses a concept of attaching and detaching a detachable lens by overlapping a lens of a main spectacle with a clip. However, in such a case, only the lens function is changed and used for dustproof spectacles or the like. In addition, the attached detachable lens is not necessarily attached stably and firmly.
