Permanently Mountable Frame Assembly For Interchangeable Sheet Media Display

A method for displaying sheet media, comprising:

• permanently attaching a back frame section to a surface;
• selecting a front frame section having a transparent barrier;
• placing a sheet medium so that it will be behind said transparent barrier;
• and
• removably securing said front frame section to said back frame section.

A frame assembly for the display of interchangeable sheet media, comprising:

• a back frame section adapted for rigid attachment to a surface;
• a front frame section adapted for removable securement to said back frame section;
• a transparent barrier on said front frame section;
• a media-carrying region behind said barrier for receiving a sheet medium for display;
• said back frame section nesting within said front frame section and comprising mounting holes for receiving fasteners for attachment of said back frame section to said surface;
• said securement of said front frame section being provided by one or more bracket members on a flange of said back frame section engaging a corresponding number of blind apertures on a flange of said front frame section;
• a security locking mechanism for removable attachment of said front frame section to said surface;
• said security locking mechanism comprising a security clip on said front frame section and a security locking fastener adapted to engage said security clip and said surface when said front frame section is positioned for attachment to said surface;
• said security locking clip and said security locking fastener being situated between said front frame section and said surface so as to be inaccessible when said front frame section is positioned for attachment to said surface except by way of a security tool that operates said security locking fastener;
• said security tool being adapted for insertion between said back frame section and said surface and including a key notch adapted to engage said security locking fastener;
• said security locking fastener comprising a threaded stem for engaging said surface, a key-receiving shank for receiving said security tool, and a tabbed head member for engaging said security locking clip;
• security clip comprising a slot that receives said security locking fastener, said slot being sized to receive said shank and to allow said tabbed head to pass therethrough in a first orientation while preventing said tabbed head from passing therethrough in a second orientation;
• said first and second orientations being determined by a rotational position of said security locking fastener;
• said rotational position of said security locking fastener being adjustable by way of said security tool;
• and
• said back frame section having a substantially rectangular cross-sectional shape and said front frame section having a decorative irregular cross-sectional shape;
• whereby said sheet medium can be removed from said frame assembly and exchanged with another sheet medium by manipulating said front frame section while said back frame section remains rigidly attached to said surface.
