ABSTRACT:
The picture frame assembly includes a frame of injection molded plastic, such as polyethylene, polypropylene or the like, or a laminate of injection molded plastic and film, or aluminum. The frame defines a viewing window which may be covered by a sheet of transparent glass or plastic in the frame. A backboard is used in the frame behind the window, which backboard includes an outer frame-supporting perimeter and an openable, hinged, generally central portion. When closed, the central portion also supports the frame. Preferably, the backboard comprises foldable material such as paperboard, cardboard, stiff cloth or paper, or the like, with the hinged thereof being a fold line at the base of the openable portion, the latter being defined by a cut line separating it from the perimeter. A finger hole may be provided to aid in moving the openable portion. A mask is disposed between the backboard and sheet of glass or plastic and may be a separate sheet with one or more picture openings and a masking perimeter blocking view of the finger hole, cut line and fold line. Alternatively, the mask may be silk screened on the inner surface of the glass or plastic sheet and serve the same purpose. Support inserts may be secured to the back of the frame over the backboard and optionally releasably hold a central portion closed.
