Child resistant flint lighter with free wheel

Abstract

A child resistant flint lighter having a body on which a pair of brackets are formed, a pivotal means being of bar-shaped and installed on the pair of brackets, a free wheel rotatably installed on the pivotal means, a flint wheel covering on the pivotal means, a fixed wheel covering on the pivotal means and fixed with respect to the flint wheel, a flint with respect of which the flint wheel and fixed wheel is able to rotate, and a flint spring pressing the flint on the flint wheel. In this invention, there is only one bar-shaped pivotal means needed in stead of the complex shafts in the conventional lighter. It will significantly reduce the complexity and time of manufacturing and assembling the pivotal means to the lighter.

1 . A lighter comprising a body on which a pair of brackets are formed, a pivotal means being of bar-shaped and installed on said pair of brackets, a free wheel rotatably installed on said pivotal means, a flint wheel covering on said pivotal means, a fixed wheel covering on said pivotal means and fixed with respect to said flint wheel, a flint with respect of which said flint wheel and fixed wheel is able to rotate, and a flint spring pressing said flint on said flint wheel. 
   
   
       2 . The lighter as claimed in  claim 1 , wherein said pivotal means is two basically identical shorter bars. 
   
   
       3 . The lighter as claimed in  claim 1 , wherein a radius of said free wheel is of 0.1 to 1.0 millimeter greater than a radius of said fixed wheel. 
   
   
       4 . The lighter as claimed in  claim 2 , wherein a radius of said free wheel is of 0.1 to 1.0 millimeter greater than a radius of said fixed wheel. 
   
   
       5 . The lighter as claimed in  claim 1 , wherein a thickness of said free wheel is 0.8 to 1.2 millimeter. 
   
   
       6 . The lighter as claimed in  claim 2 , wherein a thickness of said free wheel is 0.8 to 1.2 millimeter. 
   
   
       7 . The lighter as claimed in  claim 1 , wherein said flint wheel and said fixed wheel are loose-fitted to said pivotal means. 
   
   
       8 . The lighter as claimed in  claim 1 , wherein said flint wheel and said fixed wheel are close-fitted to said pivotal means.
