Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
149 words
A paint shield for carpets or the like comprising a first substantially planar portion (1) of sheet-like material having a handle means (3) thereon for manipulating the paint shield; a second portion (2) of sheet-like material integral with said first portion extending downwardly with respect to the first portion at an obtuse angle to form a hollow between said portions for overlapping at least a portion of a carpet adjacent a given surface within the hollow, the free length wise edge of the second portion having a serrated pattern (9, 10) forming closely spaced, adjacently located points to provide for essentially point contact between the free lengthwise edge of the paint shield and the given surface, and to retain paint or the like at the top surface of the paint shield and prevent the paint from dripping off the free edge of the second portion and towards the carpet.
