Abstract: A framed window pane paint hand-held semi-flexible plastic pane-shield positionable against a substantially right-angled corner of a window frame, the pane-shield having a linear edge continuous with a bottom surface of its flange. The linear edges of the hand-held pane-shield intersect at up to a ninety-degree angle or more. The pane shield's bottom surface angles upwardly from its linear edge at an angle of about 20 degrees relative to a mounted window pane surface. The intersecting flanges and their linear edges are each about 4 or more inches in length and each is sufficiently flexible as to expand, relative to the other, to sharply engage and flushly fit along a window frame edging having an edging corner that ranges from slightly less than 90 degrees possibly to greater than 90 degrees.

Abstract: A framed window pane paint shield device has two separate biased-apart pane-shields positionable against and between diagonally opposite right angled corners of a window frame, each pane-shield having a linear edge continuous with a bottom surface of its flange. The linear edges of each pane-shield intersect at a ninety degree angle. Each pane shield's bottom surface angling upwardly from its linear edge at an angle of about 20 degrees relative to a mounted window pane surface while the two pane-shields are biased-apart by an axial-extending compression helical spring mechanism. One of the flanges and its linear edge is about 4 inches in length and the intersecting other linear edge is about 7 inches in length and each is sufficiently thin as to sharply engage the window frame adjacent the window panel.
