Abstract
Abstract An assembly for displaying panels, for example, a picture frame, comprises a frame member having a display opening therein. The frame member has a front face, which is the face facing a viewer looking at the panel or picture displayed in the frame member, and an opposite rear face. A rearwardly facing peripheral shoulder is formed about the perimeter of the display opening so that the size of the display opening in the rear face is larger than its size in the front face. A flexible back closure member is affixed by tongue and groove locking formations across the rear of said display opening to maintain panels (e.g., a glass panel, a picture, and a backing board) within said display opening with the peripheral portions thereof seated against the peripheral shoulder.

Independent Claim
371 words
An assembly for displaying one or more panels comprises: a. a frame member having an outer periphery, a front face and an oppositely facing rear face; b. a display opening extending axially through said frame member, the perimeter of said display opening defining the inner periphery of said frame member; c. a retaining shoulder formed about said perimeter of said display opening and adapted to have seated thereon a peripheral edge portion of the frontmost one of said one or more panels, said retaining shoulder being defined by (1) a rearwardly facing ledge disposed intermediate of said front face and rear face and (2) a side wall extending from said ledge towards said rear face and terminating therein so that said display opening is larger in the rear face portion thereof than it is in the front face portion thereof; d. a first locking formation comprising one of a tongue and a groove, said first locking formation being disposed about the perimeter of said display opening and axially rearwardly of said ledge to define between said ledge and said first locking formation a mounting space to receive said panels; e. at least one closure member, a portion at least of which is flexible, having edges and being of bowed resilient construction in the free state, and affixed to said frame member by engagement of said first locking formation with a second locking formation as defined herein below; f. said second locking formation being complementary to said first locking formation and comprising the other of said tongue and groove, said second locking formation being located on said closure member adjacent at least two opposite ones of said edges thereof; said first and second locking formations being engageable with each other by flexing a portion of said closure member to engage said second locking formation thereof with respective portions of said first locking formation whereby said closure member is locked onto said frame transversely across at least a portion of the rear face portion of said display opening and in contact with and deformed against the rearmost one of said one or more panels to bias said one or more panels against said ledge and thereby retain said panels within said mounting space.
