Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
215 words
A method for spray painting one surface and effieciently shielding an adjacent surface using a large flexible masking blade and gripping means on said blade comprising: using a gripping means comprising an elongate handle; placing the front edge of said blade along a corner edge formed between said surface to be painted and said adjacent surface; pushing said gripping means to form a bend in said masking until said masking blade flexes to an angle of about 40° to 80° without permanent deformation of said blade; spray painting said surface to be painted using a spray gun, said gun being held a convenient distance from said blade thereby causing a paint dispersion with overspray of paint, one end of said gripping means being of sufficient distance from the front edge of said blade length, that upon flexing of the blade, a user's hand holding said gripping means is not reached by said overspray; and providing said masking blade to be of sufficient large height and width that even though said spray paint gun is held at a convenient spraying distance from said blade, said adjacent surface is shielded from said overspray such that said blade does not allow said overspray to reach under said blade to damage said adjacent surface being shielded from said overspray.
Claim 2
Independent Claim
215 words
A method for spray painting one surface and effieciently shielding an adjacent surface using a large flexible masking blade and gripping means on said blade comprising: using a gripping means comprising an elongate handle; placing the front edge of said blade along a corner edge formed between said surface to be painted and said adjacent surface; pushing said gripping means to form a bend in said masking until said masking blade flexes to an angle of about 40° to 80° without permanent deformation of said blade; spray painting said surface to be painted using a spray gun, said gun being held a convenient distance from said blade thereby causing a paint dispersion with overspray of paint, one end of said gripping means being of sufficient distance from the front edge of said blade length, that upon flexing of the blade, a user's hand holding said gripping means is not reached by said overspray; and providing said masking blade to be of sufficient large height and width that even though said spray paint gun is held at a convenient spraying distance from said blade, said adjacent surface is shielded from said overspray such that said blade does not allow said overspray to reach under said blade to damage said adjacent surface being shielded from said overspray.
Claim 3
Dependent Claim
20 words
The method of claim 1 wherein said blade has a reinforced back edge permitting flexing along the longitudinal axis only.
Claim 4
Dependent Claim
44 words
The method of claim 2 wherein said reinforced back edge has a sufficiently small width relative to the total width of said blade that although said back edge is stiffer than said blade, said blade easily flexes to an angle of about 40° to80°.
Claim 5
Dependent Claim
16 words
The method for shielding defined in claim 1 wherein said masking member is high impact styrene.
Claim 6
Dependent Claim
17 words
The method for shielding defined in claim 1 wherein said blade portion is about 0.06 inch thick.
