Cap with hinged ultraviolet ray visor

摘要

A cap with a hinged ultraviolet ray visor is disclosed. The ultraviolet ray visor or a main visor is made of a transparent or translucent material capable of intercepting ultraviolet rays, and is rotatably attached to both sides of an elastic head band at both ends thereof by two joint pins. In an embodiment, an auxiliary visor is attached to both sides of the head band at both ends thereof by the two joint pins so as to be positioned between the head band and the main visor. The angular position of the main visor relative to the head band is easily adjusted by a user when necessary.
