Electrically controlled pitch adjustable flat panel display bracket

Abstract

An electrically controlled pitch adjustable flat panel display bracket has a base, a frame, a driving device and at least one display rack. The frame is attached securely to the base. The driving device has a driving device body and an extending arm. The display rack is pivotally mounted inside the frame, protrudes out of the frame for attaching a flat panel display (FPD) and is pivotally mounted on the extending arm. The driving device body may be actuated by a remote control to extend and retract the extending arm to adjust a pitch of the FPD conveniently.

1 . An electrically controlled pitch adjustable flat panel display bracket comprising:
 a frame having
 a body being tubular and having
 a proximal end being attached to the flat surfaces; 
 a distal end; 
 a front surface; 
 an inner surface; and 
 an opening being formed on the front surface of the body; 
 
   a driving device having a controllably changeably length, being mounted on the inner surface of the body, being electronically controlled to change the length and having
 a driving device body being securely mounted on the inner surface of the body; and 
 an extending arm being telescopically mounted on the driving device body and having a distal end and being electronically controlled to move the distal end away and toward the driving device body; and 
   at least one display rack and each one of the at least one display rack being pivotally mounted on the inner surface of the body, protruding out of the frame and being pivotally mounted on the distal end of the extending arm.   
   
   
       2 . The electrically controlled pitch adjustable flat panel display bracket as claimed in  claim 1 , wherein
 the frame further has a cover corresponding to the opening of the body, detachably covering the opening of the body and having a rack opening; and   the at least one display rack protrudes out of the rack opening and each one of the at least one display rack has
 a rack bracket having
 a fastening surface being securely mounted on the inner surface of the body; and 
 a pivotal surface being connected parallelly to the fastening surface and having
 a guide slot being formed through the fastening surface; and 
 a fulcrum hole being formed through the fastening surface adjacent to the guide slot; and 
 
 
 a pivot rack having
 a proximal surface being pivotally mounted on the pivotal surface of the rack bracket; 
 a distal surface being perpendicular to the proximal surface and protruding out of the frame through the rack opening; 
 a fulcrum hole being formed through the proximal surface close to the distal surface and being pivotally mounted to the fulcrum hole; and 
 a guide hole being formed through the proximal surface of the pivot rack adjacent to the fulcrum hole of the pivot rack; and 
 
   the at least one display rack further has a pivotal mounting assembly having
 a hub assembly being mounted on the distal end of the extending arm; and 
 a bolt being mounted through each guide hole and guide slot and the hub assembly and the distal end of the extending arm to guide and limit movement of the distal end of the extending arm. 
   
   
   
       3 . The electrically controlled pitch adjustable flat panel display bracket as claimed in  claim 2  further having a base being comprising at least one disc and having a top surface and the frame being attached securely to the top surface of the base. 
   
   
       4 . The electrically controlled pitch adjustable flat panel display bracket as claimed in  claim 2 , wherein the electrically controlled pitch adjustable flat panel display bracket has two display racks being symmetrically mounted on the inner surface of the body and being pivotally mounted on the distal end of the extending arm. 
   
   
       5 . The electrically controlled pitch adjustable flat panel display bracket as claimed in  claim 3 , wherein the electrically controlled pitch adjustable flat panel display bracket has two display racks being symmetrically mounted on the inner surface of the body and being pivotally mounted on the distal end of the extending arm. 
   
   
       6 . The electrically controlled pitch adjustable flat panel display bracket as claimed in  claim 4 , wherein the guide slot is arced. 
   
   
       7 . The electrically controlled pitch adjustable flat panel display bracket as claimed in  claim 5 , wherein the guide slot is arced.
