Abstract An image exhibiting member having a screen at which images appear, preferably a television receiver, is provided in combination with first and second panels positioned one at either side of the screen and projecting forwardly therefrom and a third panel hingedly mounted above the screen for movement in a first plane into cooperating relationship with the first and second panels to provide a light shield for the screen. The third panel has first, second and third segments, the second segment being positioned intermediate the first and third segments. The first and third segments are hingedly connected to the second segment for movement in planes different from the plane of movement of the second segment.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
166 words
In combination, an image-exhibiting member having a screen on which images appear; first and second panels positioned at opposite sides of said screen and projecting forwardly therefrom, said first and second panels mounted, respectively, for pivotal movement about substantially vertical axes at opposite sides of said screen; a third panel hingedly mounted above said screen about a substantially horizontal axis for movement in a first plane into cooperating relationship with said first and second panels to provide a light shield for said screen; said third panel having first, second and third segments, said second segment positioned intermediate said first and third segments, said first and third segments hingedly connected along one side to opposite sides, respectively, of said second segment so that said first and second panels may be moved about their respective hinged axes and said first and third segments will pivot about their hinged axes to remain in cooperative engagement with said first and second panels at all times to maintain said light shield.
