ABSTRACT:
A computer monitor hood for use in conjunction with a computer monitor having a top surface, left and right side surfaces, and a forwardly facing screen, is disclosed. The computer monitor hood comprises a top shading panel having a front edge, a rear edge, and left and right side edges. Left and right side shading panels are operatively attached to the top shading panel and are disposed in generally vertically oriented relation to the left and right side edges of the top shading panel, respectively. The left and right side shading panels each have front, rear, and bottom edges. A front-to-rear main axis extends from the front edges to the rear edges of the shading panels. When the computer monitor hood is in place on a computer monitor, the top, left and right shading panels each project forwardly from the front of the computer monitor, at the respective of the top, left side, and right side surfaces of the computer monitor, so as to shade the screen of the computer monitor. A counterweight is operatively mounted in selectively movable relation on the computer monitor hood in any one of a plurality of front-to-rear positions so as to permit the counterweight to balance the computer monitor hood at a selected position on the computer monitor. Typically, at this selected position, the computer monitor hood is positioned as far forwardly as reasonably possible and is tilted downwardly, as balanced by the counterweight, so as to provide maximum shading for the screen of the computer monitor.
