Computer monitor support

Abstract

A computer monitor support includes a first support immovably connected to a lower side of a desktop, and a second support pivotally connected to the first support via an upper and a lower link to movably located in front of the first support for supporting a computer monitor thereon. The first and the second support, and the upper and the lower link together form a four-bar linkage. A lifting mechanism is connected to the four-bar linkage to lift or lower the second support and to incline the second support downward or upward, respectively, at the same time, so that any user may set the computer monitor on the second support to a vertical position and an angle of elevation most suitable for the user to look at a display on the monitor comfortably and clearly.

What is claimed is:  
     
         1 . A computer monitor support, comprising: 
 a first support including a first top plate immovably connected to a lower side of a desktop, and a first upright bracket fixedly connected to a bottom of said first top plate; said first upright bracket having a U-shaped cross section to include two sidewalls and a sideward opening that is oriented forward, and being provided on said two sidewalls with a first pair of upper connection holes and a first pair of lower connection holes;    a second support being located in front of said first support, and including a second top plate on which a computer monitor is seated, and a second upright bracket fixedly connected to a bottom of said second top plate; said second upright bracket having a U-shaped cross section to include two sidewalls and a sideward opening that is oriented toward said first support, and being provided on said two sidewalls with a second pair of upper connection holes and a second pair of lower connection holes;    a first link having a U-shaped cross section to include two sidewalls and a sideward opening that is oriented downward; said first link being provided on said two sidewalls near two ends thereof with a first pair of rear connection holes and a first pair of front connection holes;    a second link being located below said first link, and having a U-shaped cross section to include two sidewalls and a sideward opening that is oriented upward; said second link being provided on said two sidewalls near two ends thereof with a second pair of rear connection holes and a second pair of front connection holes; and    a lifting mechanism including an extension tube being driven by a motor and a lead screw of said lifting mechanism to extend forward or retreat;    said first link being pivotally connected at a rear end to said first upright bracket by extending a first upper pivot shaft through said first pair of upper connection holes on said first upright bracket and said first pair of rear connection holes on said first link, and at a front end to said second upright bracket by extending a second upper pivot shaft through said second pair of upper connection holes on said second upright bracket and said first pair of front connection holes on said first link;    said second link being pivotally connected at a rear end to said first upright bracket by extending a first lower pivot shaft through said first pair of lower connection holes on said first upright bracket and said second pair of rear connection holes on said second link, and at a front end to said second upright bracket by extending a second lower pivot shaft through said second pair of lower connection holes on said second upright bracket and said second pair of front connection holes on said second link; and    said first lower pivot shaft connecting said first upright bracket to said rear end of said second link also extending through a rear locating block of said lifting mechanism, and said second upper pivot shaft connecting said second upright bracket to said front end of said first link also extending through an outer end of said extension tube.    
     
     
         2 . The computer monitor support as claimed in  claim 1 , wherein a distance between said second pair of rear connection holes and said second pair of front connection holes on said second link is slightly larger than a distance between said first pair of rear connection holes and said first pair of front connection holes on said first link.  
     
     
         3 . The computer monitor support as claimed in  claim 1 , wherein a distance between said second pair of upper connection holes and said second pair of lower connection holes on said second upright bracket is slightly larger than a distance between said first pair of upper connection holes and said first pair of lower connection holes on said first upright bracket.
