Adjustable mounting device for mounting an optical engine in a display apparatus

Abstract

An adjustable mounting device includes a base, first and second linearly displaceable support units, and first and second tiltable support units. The first linearly displaceable support unit is mounted movably on the base, and is operable to move along a first axis relative to the base. The first tiltable support unit is mounted pivotally to the first linearly displaceable support unit, and is operable to pivot about a second axis relative to the base. The second linearly displaceable support unit is mounted movably on the first tiltable support unit, and is operable to move along the second axis relative to the base. The second tiltable support unit is mounted pivotally to the second linearly displaceable support unit, and is operable to pivot about the first axis relative to the base.

1 . An adjustable mounting device for mounting an optical engine in a display apparatus, said adjustable mounting device comprising: 
 a base;    a first linearly displaceable support unit mounted movably on said base, and operable to move along a first axis relative to said base;    a first tiltable support unit mounted pivotally to said first linearly displaceable support unit, and operable to pivot about a second axis relative to said base;    a second linearly displaceable support unit mounted movably on said first tiltable support unit, and operable to move along the second axis relative to said base; and    a second tiltable support unit mounted pivotally to said second linearly displaceable support unit, and operable to pivot about the first axis relative to said base.    
   
   
       2 . The adjustable mounting device as claimed in  claim 1 , wherein said base includes a platform, said first linearly displaceable support unit including a support plate and at least one guiding mechanism, said guiding mechanism including a guide slot that is formed in one of said platform and said support plate, and that extends along the first axis, and a guide pin that is provided on the other one of said platform and said support plate, and that extends through said guide slot.  
   
   
       3 . The adjustable mounting device as claimed in  claim 1 , wherein said first linearly displaceable support unit includes: 
 a support plate;    first coupling lug mounted on said base;    a second coupling lug mounted on said support plate, and registered with said first coupling lug along the first axis; and    a driving member engaged threadedly with said second coupling lug and secured rotatably to said first coupling lug.    
   
   
       4 . The adjustable mounting device as claimed in  claim 1 , wherein said first tiltable support unit includes: 
 a pair of pivot lugs mounted on said first linearly displaceable support unit and registered with each other along the second axis;    a support plate mounted pivotally to said pair of pivot lugs; and    a driving member engaged threadedly with said first linearly displaceable support unit and secured rotatably to said support plate.    
   
   
       5 . The adjustable mounting device as claimed in  claim 1 , wherein said second linearly displaceable support unit includes a support plate and at least one guiding mechanism, said guiding mechanism including a guide slot that is formed in one of said first tiltable support unit and said support plate, and that extends along the second axis, and a guide pin that is provided on the other one of said first tiltable support unit and said support plate, and that extends through said guide slot.  
   
   
       6 . The adjustable mounting device as claimed in  claim 1 , wherein said second linearly displaceable support unit includes: 
 a support plate;    a first coupling lug mounted on said first tiltable support unit;    a second coupling lug mounted on said support plate, and registered with said first coupling lug along the second axis; and    a driving member engaged threadedly with said second coupling lug and secured rotatably to said first coupling lug.    
   
   
       7 . The adjustable mounting device as claimed in  claim 1 , wherein said second tiltable support unit includes: 
 a pair of pivot lugs mounted on said second linearly displaceable support unit and registered with each other along the first axis;    a support plate mounted pivotally to said pair of pivot lugs; and    a driving member engaged threadedly with said second linearly displaceable support unit and secured rotatably to said support plate.
