Hinge

Abstract

A hinge mounted between a cover and a base of a notebook has a base bracket having a mounting hole, a cover bracket having a stationary hole, a limiting spacer and a pintle. The limiting spacer is mounted securely on one side of the base bracket and has a mounting hole and a limiting flange. The pintle has a proximal end mounted securely in the stationary hole of the cover bracket, a distal end mounted rotatably through the mounting hole of the limiting spacer and the mounting hole of the base bracket, and a head formed near the proximal end. The head has a limiting protrusion selectively abutting a front end or a rear end of the limiting flange to keep the cover of the notebook in position when the cover being closed or opened and to prevent the base bracket from resulting stress concentration.

1 . A hinge adapted for a notebook comprising: 
 a base bracket having 
 a mounting hole formed through the base bracket; and  
 a side;  
   a cover bracket having a stationary hole formed through the cover bracket;    a limiting spacer mounted securely on the side of the base bracket and having 
 a top;  
 a mounting hole formed through the limiting spacer and corresponding to the mounting hole of the base bracket; and  
 a limiting flange formed on and protruding axially from the top of the limiting spacer and having 
 a front end; and  
 a rear end;  
 
   a pintle extending through the limiting spacer, the base bracket and the cover bracket and having 
 a proximal end mounted securely in the stationary hole of the cover bracket;  
 a distal end mounted rotatably through the mounting hole of the limiting spacer and the mounting hole of the base bracket and having an outer thread defined around the distal end of the pintle; and  
 a head formed near the proximal end of the pintle and having 
 an annular edge; and  
 a limiting protrusion formed on and protruding from the annular edge of the head of the pintle and selectively abutting the front end and the rear end of the limiting flange of the limiting spacer; and  
 
   a nut mounted around the distal end of the pintle and screwing onto the outer thread of the distal end.    
     
     
         2 . The hinge as claimed in  claim 1 , wherein the limiting flange of the limiting spacer is curved.  
     
     
         3 . The hinge as claimed in  claim 2 , wherein the limiting protrusion of the head of pintle is curved.  
     
     
         4 . The hinge as claimed in  claim 1 , wherein 
 the base bracket further has a positioning hole defined through the base bracket and located below the mounting hole of the base bracket; and    the limiting spacer further has 
 a riveting hole formed through the limiting spacer and corresponding to the positioning hole of the base bracket; and  
 a rivet mounted through the positioning hole of the base bracket and the riveting hole of the limiting spacer.  
   
     
     
         5 . The hinge as claimed in  claim 2 , wherein 
 the base bracket further has a positioning hole defined through the base bracket and located below the mounting hole of the base bracket; and    the limiting spacer further has 
 a riveting hole formed through the limiting spacer and corresponding to the positioning hole of the base bracket; and  
 a rivet mounted through the positioning hole of the base bracket and the riveting hole of the limiting spacer.  
   
     
     
         6 . The hinge as claimed in  claim 3 , wherein 
 the base bracket further has a positioning hole defined through the base bracket and located below the mounting hole of the base bracket; and    the limiting spacer further has 
 a riveting hole formed through the limiting spacer and corresponding to the positioning hole of the base bracket; and  
 a rivet mounted through the positioning hole of the base bracket and the riveting hole of the limiting spacer.  
   
     
     
         7 . The hinge as claimed in  claim 1 , wherein 
 the base bracket further has a positioning hole defined through the base bracket, located below and communicating with the mounting hole of the base bracket; and    the limiting spacer further has a positioning protrusion formed on and extending from the limiting spacer and inserting into the positioning hole of the base bracket.    
     
     
         8 . The hinge as claimed in  claim 2 , wherein 
 the base bracket further has a positioning hole defined through the base bracket, located below and communicating with the mounting hole of the base bracket; and    the limiting spacer further has a positioning protrusion formed on and extending from the limiting spacer and inserting into the positioning hole of the base bracket.    
     
     
         9 . The hinge as claimed in  claim 3 , wherein 
 the base bracket further has a positioning hole defined through the base bracket, located below and communicating with the mounting hole of the base bracket; and    the limiting spacer further has a positioning protrusion formed on and extending from the limiting spacer and inserting into the positioning hole of the base bracket.    
     
     
         10 . The hinge as claimed in  claim 1 , wherein 
 the stationary hole of the cover bracket is non-circular; and    the proximal end of the pintle is non-circular and corresponds to the stationary hole of the cover bracket.
