  • Patent number: 5448405
    Abstract: A glare filter for use with a visual display terminal having a display screen on its forward side is disclosed. The glare filter includes a filter screen, a mount, and couplings. The filter screen has lateral edges, a top edge, and a bottom edge. A mount is secured to the terminal and includes two lateral guides that form channels. The distance between the channels is slightly larger than the width of the filter screen to slidably receive the lateral edges of the filter screen. The channels are oriented generally transverse to the surface of the display screen, such that the filter screen may be held above the terminal and above the display screen. The couplings extend from the filter screen and slidably and pivotally engage within the channels of the lateral guides. The couplings are pivotally movable relative to the mount when the filter screen is extended to a forwardmost position relative to the mount. This allows the filter screen to be pivoted downwardly to a position overlying the display screen.
