Collapsible bookcase

Abstract

The disclosed collapsible bookcase has generally rigid planar rear and side panels, and first couplings provided between them operable to pivot the side panels approximately 270 degrees between a collapsed condition with the side panels closely adjacent and generally parallel to the rear side of the rear panel and a set-up condition with the side panels angled normal to and forwardly away from the front side of the rear panels. Generally rigid planar shelves are pivoted by second couplings between the rear ends of the shelves and the rear panels operable to pivot the shelves approximately 90 degrees between a collapsed condition having the shelves adjacent and generally parallel to the front side of the rear panel and a set-up condition extended between the end panels and at different vertical spacings from one another. Supports between the end panels and shelves hold them in the set-up condition.

1 . A collapsible bookcase comprising 
 generally rigid planar rear and side panels, and first couplings provided between the rear and side panels operable to pivot them approximately 270 degrees between a set-up condition having the side panels angled forwardly away from the front side of the rear panels and a collapsed condition having the side panels arranged in side by side association closely adjacent and generally parallel to the rear side of the rear panel;    generally rigid planar shelves, and second couplings provided between the rear ends of the shelves and the rear panels and in alignment between the side panels and at different spacings from one another, operable to pivot the shelves approximately 90 degrees between a set-up condition having them angled forwardly away from the front side of the rear panels and a collapsed condition having them arranged in side by side association closely adjacent and generally parallel to the front side of the rear panel; and    supports provided between the side panels and shelves operable to hold them in the set-up condition.    
   
   
       2 . A collapsible bookcase according to  claim 1 , further comprising the first and second couplings and said supports each consisting of complementary sections integrally formed  
   
   
       3 . A collapsible bookcase according to  claim 1 , further comprising the first couplings being proximate the sides of the rear panel and proximate the rear of each side panel.  
   
   
       4 . A collapsible bookcase according to  claim 1 , further comprising the supports being on the forward edge of each side panel and underlying and interlocking with forward edges of each shelf.  
   
   
       5 . A collapsible bookcase according to  claim 1 , further comprising the first couplings being proximate the side edges of the rear panel and proximate the rearward edge of each side panel, and the supports being on the forward edge of each side panel and underlying and interlocking with forward edges of each shelf.  
   
   
       6 . A collapsible bookcase according to  claim 5 , further comprising the first and second couplings and said supports each being integrally formed respectively on the paired panels, and on the panel cooperating with the shelf.  
   
   
       7 . A collapsible bookcase according to  claim 1 , further comprising complementary nesting structures on top and bottom edges of the rear and side panels suited to allow like collapsible bookcases to be stacked vertically on one another with the structures suitably nested.  
   
   
       8 . A collapsible bookcase according to  claim 6 , further comprising complementary nesting structures on top and bottom edges of the rear and side panels suited to allow like collapsible bookcases to be stacked vertically on one another with the structures suitably nested.  
   
   
       9 . A collapsible bookcase according to  claim 8 , further comprising the first and second couplings and said supports each being integrally formed respectively on the paired panels, and on the panel cooperating with the shelf.
