  • Patent number: 7029535
    Abstract: Paint shields formed from relatively stiff but pliable material are configured to cover the transparent or translucent lenses of light fixtures so that frames of the fixtures which extend perimetrically about the lenses can be painted by brush, by roller or by spray without getting paint on the lenses. Edge regions of the paint shields are configured to be inserted between the frames and the lenses, and central regions of the paint shields preferably are transparent or translucent to permit light from the fixtures to pass through the installed paint shields. Peripheral regions of the shields preferably are provided with visible guide formations or may be scored or perforated to facilitate trimming the shields to fit small and undersized fixtures. Central portions may be designed to fold away from other portions of the shields to stiffen the installed shields to minimize sagging.

  • Patent number: 7022187
    Abstract: The present invention relates to an apparatus as well as systems and methods for masking ceiling or wall fixtures, such as recessed light fixtures, during residential and commercial painting and drywalling. Through the use of an insert mask, a user can quickly and safely mask a fixture without the use of special tools or ladders. Typically, the user positions the insert within a defined opening on the ceiling or wall fixture. The insert is fully inserted into the opening whereby a retaining surface on the insert creates a friction fit between the fixture and the insert. While the insert frictionally resides within the opening, any overspray or misapplication of painting or drywalling material is captured by a protective surface of the insert. Following the material application process, the insert can be removed from the fixture. In an embodiment, the insert mask system includes an insertion tool for insertion and removal of the insert from the fixture.

  • Patent number: 6955726
    Abstract: A mask frame assembly includes a frame having an opening and a mask having at least two unit mask elements. Both ends of each unit mask element are fixed to the frame in a state of tension. The unit mask elements include a unit masking pattern, and overlap each other on a predetermined width to form a single mask pattern block. Each unit mask element has a recessed wall in an overlapping portion thereof so as to maintain the thickness of the mask constant at an overlap between the unit mask elements. Accordingly, the mask frame assembly reduces distortion in an evaporation pattern due to an increase in the size of a mask pattern, facilitates the adjustment of a total pitch of evaporation patterns, and prevents evaporation from occurring at undesired positions.
