Abstract

Abstract An extremely simple and inexpensive light shield or shroud for television screens, adjustable in nature, for encirlcing the screen of a television set (or the front end of the set itself), thus enabling viewing of the screen in sunlight or other areas where excessive light reduces the contrast in the screen such as to otherwise prevent adequate viewing. In collapsed form, the shield lies flat for shipment or storage purposes, yet it can be readily pivoted in place, with the two adjustable sides being pivotally positioned together with an adjustable top and bottom, and then conformed in dimension to the top, bottom and sides of the television set, thus to adequately shield the screen from sunlight (or artificial glare) by the resultant rectangular enclosure. The entire assembly is comprised of four identically shaped sections of cardboard or equivalent material, each of which is scored near the mid-section thereof in order that each of these elements can be configured to a right-angular shape and pivotally interconnected, thus to form the desired rectangular shape. At the forward end (away from the television screen), each of these elements is provided with apertures on each side of the widest end thereof, and these are adapted to interfit with like apertures in an adjacent right-angular configuration. These apertures permit the insertion of a suitable pressure applied grommet or equivalent, thus permitting adjustment, and fixed adjustment of the adjacent elements to different sized television screens.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 141 words
An adjustable shield for a screen of an apparatus enabling imposition of images thereon comprising four foldable and interconnecting sections, each of said sections being of approximately the same size in overall length and width, each of said sections being adapted to be folded by folding means intermediate the width thereof thereby to be positioned in right angular configuration, each of said sections at one end thereof having an aperture on each side thereof, each of said sections when in said configuration overlapping an adjacent section that sufficient amount to place the side apertures of one section in alignment with the side apertures of the adjacent section, and pivot pin means in each of said aligned apertures, whereby said sections at the opposite ends thereof form a rectangular opening of adjustable size to fit different sizes of said apparatus and screen.
Claim 2
Dependent Claim 141 words
An adjustable shield for a screen of an apparatus enabling imposition of images thereon comprising four foldable and interconnecting sections, each of said sections being of approximately the same size in overall length and width, each of said sections being adapted to be folded by folding means intermediate the width thereof thereby to be positioned in right angular configuration, each of said sections at one end thereof having an aperture on each side thereof, each of said sections when in said configuration overlapping an adjacent section that sufficient amount to place the side apertures of one section in alignment with the side apertures of the adjacent section, and pivot pin means in each of said aligned apertures, whereby said sections at the opposite ends thereof form a rectangular opening of adjustable size to fit different sizes of said apparatus and screen.
Claim 3
Dependent Claim 17 words
The invention as defined in claim 1 wherein said pivot pin means comprises a pressure applied grommet.
Claim 4
Dependent Claim 18 words
The invention as defined in claim 1 wherein said pivot pin means comprises a screw threaded type grommet.
Claim 5
Dependent Claim 71 words
The invention as defined In claim 1 wherein said folding means comprises a score line across each of said sections to permit positioning of one half of one side of each section at an approximate right angle to the other half of the other side of each section, whereby when said halves are so positioned each section when overlapped with an adjacent section will form an approximate rectangle in cross-sectional configuration.
Claim 6
Dependent Claim 53 words
The invention as defined in claim 1 wherein there are a plurality of said apertures on each side of each of said sections at said one end thereof, thereby to permit greater adjustment of size of said shield via adjustment of the positioning of the amount of overlap of adjacent of said sections.
Claim 7
Dependent Claim 22 words
The invention as defined in claim 5 wherein at least three apertures are provided on each side of each of said sections.
