Picture frame assembly

Abstract

A picture frame assembly incorporates at least one angled slotted shim tab and preferably a plurality of angled slotted shim tabs each movably mounted on a backing member of the picture frame assembly and with each shim tab cooperating with a shim tab receiving groove circumscribed, formed, or cast in a back picture opening rabbet return of an outer frame of the frame assembly to secure an artwork within the outer frame. In use, the angled slotted shim tab is pressured into close engagement with the shim tab receiving groove by an angled slot in the shim tab acting against outer portions of a threaded insert mounted transversely in the backing member near its outer edge and a capscrew that is threaded through the angled slot and tightened to secure the shim tab to the backing member.

1 . A picture frame assembly for the display of an artwork comprising 
 a backing member, said backing member having at least one insert receiving bore located near its outer edge; each said insert receiving bore receiving and retaining therein a threaded insert;    an angled slotted shim tab associated with each said threaded insert, each said angled slotted shim tab having an angled shim tab slot and a groove engaging edge;    a capscrew associated with each said threaded insert and each said capscrew threaded through each said angled slotted shim tab and received within each said threaded insert,    an outer frame, having a back picture opening rabbet return; said rabbet return having at least one shim tab receiving groove circumscribing the perimeter of said rabbet return; and each said shim tab receiving groove sized to receive and cooperate with each said groove engaging edge of each said angled slotted shim tab.    
   
   
       2 . A picture frame assembly according to  claim 1  wherein each said groove engaging edge is single beveled.  
   
   
       3 . A picture frame assembly according to  claim 1  wherein each said groove engaging edge is double beveled.  
   
   
       4 . A picture frame assembly according to  claim 1  wherein each said groove engaging edge is a straightedge.  
   
   
       5 . A picture frame assembly according to  claim 1  wherein each said groove engaging edge is a curved edge.  
   
   
       6 . A picture frame assembly according to  claim 1  further comprising a picture support flange extending inwardly in said picture sight opening.  
   
   
       7 . A picture frame assembly for the display of artwork comprising 
 an outer frame, having a back outer frame surface and a front outer frame surface,    a back picture opening rabbet return in said back outer frame surface communicating transversely through said outer frame and joining with a front picture sight opening in said front outer frame surface, said back picture opening rabbet return extending towards said front outer frame surface, said back picture opening rabbet return having a shim tab receiving groove circumscribed around the inner perimeter of said back picture opening rabbet return and said groove spaced from said back outer frame surface,    a backing member sized to be received within said back picture opening rabbet return, said backing member having a backing member front surface, a backing member back surface, and a backing member outer edge,    an insert receiving bore transverse through said backing member and located near said backing member outer edge,    a threaded insert inserted and retained within said insert receiving bore from said backing member front surface,    an angled slotted shim tab having a groove engaging edge and an angled slotted shim tab slot, and    a capscrew threaded through said shim tab slot and engaging said threaded insert.    
   
   
       8 . A picture frame assembly according to  claim 7  wherein each said groove engaging edge is single beveled.  
   
   
       9 . A picture frame assembly according to  claim 7  wherein each said groove engaging edge is double beveled.  
   
   
       10 . A picture frame assembly according to  claim 7  wherein each said groove engaging edge is a straightedge.  
   
   
       11 . A picture frame assembly according to  claim 7  wherein each said groove engaging edge is a curved edge.  
   
   
       12 . A picture frame assembly according to  claim 7  further comprising a picture support flange extending inwardly in said picture sight opening.
