Sun visor

Abstract

A sun visor includes two head band portions extended from a central visor portion and each having one or more coupling members to couple the head band portions together and to form a head encircling device and to adjustably attach the sun visor onto a head of a user. Two or more folding lines are formed between the center visor portion and each of the head band portions, and inclined relative to each other, to form a superposed portion between the center visor portion and the head band portions after the head band portions are folded relative to the center visor portion along the folding lines, and to form a frustum-shaped structure, but not a cylindrical-shaped structure for the head encircling device.

1 . A sun visor comprising: 
 a central visor portion, and    two head band portions extended from said central visor portion and each having at least one coupling member provided therein and engageable with each other, to couple said head band portions together and to form a head encircling device and to adjustably attach said sun visor onto a head of a user, and    a first and at least one second folding lines provided and formed between said center visor portion and each of said head band portions, and inclined relative to each other, to form a superposed portion between said center visor portion and each of said head band portions after said head band portions are folded relative to said center visor portion along said folding lines, and to form a frustum-shaped structure, but not a cylindrical-shaped structure for said head encircling device.    
   
   
       2 . The sun visor as claimed in  claim 1 , wherein said at least one coupling member includes a slot formed in said head band portions respectively.  
   
   
       3 . The sun visor as claimed in  claim 1 , wherein said at least one coupling member includes a catch formed in said head band portions respectively.  
   
   
       4 . The sun visor as claimed in  claim 1 , wherein said first folding line is perpendicular to said head band portions respectively, and inclined relative to said at least one second folding line.  
   
   
       5 . The sun visor as claimed in  claim 1 , wherein said head band portions are perpendicular to said central visor portion respectively.  
   
   
       6 . The sun visor as claimed in  claim 1 , wherein said first and said at least one second folding lines include one end contacted with each other.
