Adjustable hinge assembly

Abstract

An adjustable hinge assembly has a stationary leaf, a pivoting leaf, an extending arm and a mounting bracket. The stationary leaf connects securely to a base of a portable electronic device. The pivoting leaf is connected pivotally to the stationary leaf. The extending arm is mounted slidably on the pivoting leaf. The mounting bracket is mounted rotatably in the extending arm and connects securely to a cover of the portable electronic device having a rear edge. Consequently, the adjustable hinge assembly enables the portable electronic device to have a unique appearance and change position of the cover before opening the electronic device to prevent the cover from hitting the base.

1 . An adjustable hinge assembly comprising
 a stationary leaf having
 a distal end; 
 a proximal end; and 
 a connecting tab being formed on and protruding up from the proximal end; 
   a pivoting leaf having
 a pivoting end being connected pivotally to the connecting tab of the stationary leaf; 
 a connecting end; and 
 a mounting tab being formed on the connecting end of the pivoting leaf; 
   an extending arm having
 a proximal end; 
 a middle; and 
 a sliding portion corresponding to the mounting tab of the pivoting leaf and being mounted slidably on the mounting tab of the pivoting leaf; and 
   a mounting bracket having a pivot post protruding transversely from the mounting bracket and having a distal end mounted rotatably in the extending arm.   
   
   
       2 . The adjustable hinge assembly as claimed in  claim 1 , wherein
 the sliding portion of the extending arm further has an outer surface; and
 at least two detents being formed in the outer surface of the sliding portion; and 
   the extending arm further has
 a resilient boss plate mounted securely to the connecting tab of the stationary leaf and having
 an inner surface; 
 an outer surface; and 
 a boss being formed on and protruding from the inner surface of the resilient boss plate and corresponding to and engaging one of the detents. 
 
   
   
   
       3 . The adjustable hinge assembly as claimed in  claim 2 , wherein
 the sliding portion of the extending arm further has an elongated hole being formed longitudinally through the sliding portion, aligning with the connecting holes of the mounting tab and having two ends;   the resilient boss of the extending arm further has multiple mounting holes being formed through the resilient boss plate and aligning respectively with the connecting holes of the pivoting leaf; and   the extending arm further has multiple fasteners being mounted respectively through the mounting holes of the resilient boss plate and the elongated hole of the extending arm and being secured respectively in the connecting holes of the mounting tab of the pivoting leaf.   
   
   
       4 . The adjustable hinge assembly as claimed in  claim 1 , wherein
 the connecting tab of the stationary leaf further has a top edge; and
 a gudgeon being formed through the connecting tab near the top edge; and 
   the pivoting leaf further has
 a through hole being formed through the pivoting end and aligning with the gudgeon of the connecting tab; and 
 a pintle being mounted rotatably in the gudgeon of the stationary leaf and the through hole of the pivoting leaf and having multiple washers mounted around the pintle. 
   
   
   
       5 . The adjustable hinge assembly as claimed in  claim 1 , wherein the mounting bracket further has
 multiple side tabs; and   multiple fixing holes being formed respectively through the side tabs.   
   
   
       6 . The adjustable hinge assembly as claimed in  claim 1 , wherein each mounting hole of the resilient boss plate further has a resilient lip protruding from the outer surface; and
 the fasteners of the extending arm press respectively against the resilient lips of the mounting holes.   
   
   
       7 . The adjustable hinge assembly as claimed in  claim 1 , wherein the fasteners are bolts.
