Protection of posterboard inventory

Abstract

A display rack for displaying one or more sheets of posterboard or other similar sheet material has vertical columns supporting vertically spaced apart tiers, each tier having a perimeter frame having side rails secured to and supported by the vertical columns and front and rear rails. Corner guards are secured to the perimeter frame at the intersections of the side rails and the front and rear rails and positioned for respectively receiving a corner of the posterboard, each corner guard having a bottom wall, a side wall, an end wall deployed for holding posterboard on the tier. Corner guards at the rear corners have side walls that taper or flare outwardly. Clips adapt the corner guards for retrofitting to display racks.

1 . A corner guard adapted to be retrofitted to a wire-form display rack having at least one tier with a perimeter frame and protect one or more sheets of posterboard displayed thereon, the corner guard comprising a bottom wall, a side wall and an end wall, and further comprising means for attaching the corner guard to a perimeter frame of a tier of a wire-form display rack with the corner guard overlying a portion of the perimeter frame to maintain the corner guard in a desired orientation. 
     
     
         2 . A corner guard as defined in claim I wherein the sidewall of the cornerguard is tapered outwardly toward its distal end. 
     
     
         3 . A corner guard as defined in  claim 1  wherein the sidewall of the corner guard flares outwardly adjacent its distal end. 
     
     
         4 . A corner guard as defined in  claim 1  wherein the bottom wall of the corner guard is adapted to overlie a portion of the perimeter frame. 
     
     
         5 . A corner guard as defined in  claim 1  wherein the bottom wall, side wall and end wall are unitary molded polymer. 
     
     
         6 . A corner guard as defined in  claim 2  wherein the means for attaching the corner guard to the perimeter frame of a tier of a display rack are C-shaped clips sized and adapted to retain the corner guard on a tier of the display rack. 
     
     
         7 . A corner guard as defined in  claim 6  wherein the C-shaped clips are positioned to retain the corner guard on a tier of the display rack with the end wall of the corner guard aligned with or spaced along the tier from a stop of the tier. 
     
     
         8 . A display rack for displaying one or more sheets of posterboard or other similar sheet material comprising vertical columns supporting vertically spaced apart tiers, each tier having a perimeter frame having side rails secured to and supported by the vertical columns and front and rear rails, and corner guards secured to the perimeter frame at the intersections of the side rails and the front and rear rails and positioned for respectively receiving a corner of the posterboard, each corner guard having a bottom wall, a side wall, and an end wall deployed for holding posterboard on the tier. 
     
     
         9 . A display rack as defined in  claim 8  wherein the side walls of at least the corner guards secured to the perimeter frame at the intersections of the side rails and rear rail taper outwardly to the distal ends of the sidewalls. 
     
     
         10 . A display rack as defined in  claim 8  wherein the side walls of at least the corner guards secured to the perimeter frame at the intersections of the side rails and rear rail flair outwardly adjacent the distal ends of the sidewalls. 
     
     
         11 . A display rack as defined in  claim 8  wherein the side walls of at least the corner guards secured to the perimeter frame at the intersections of the side rails and rear rail extend forwardly past rearward vertical columns. 
     
     
         12 . A display rack as defined in  claim 8  wherein the stops are positioned along the front rails of the tiers and the corner guards secured to the perimeter frame at the intersections of side rails and front rail have their end walls aligned with or spaced toward the rear rail from the stops of a tier.
