Abstract
Abstract A display shelf comprises a hollow box of stiff board material having one side open. The shelf is mounted by assembly over a relatively rigid supporting block having upper and lower surfaces spaced to slidably and frictionally contact the interior surfaces of opposite horizontal sides of said shelf. The supporting block is fastened to an upright wall and the assembly of the hollow box-like shelf upon the supporting block produces a shelf structure which conceals its own support. In an embodiment particularly suited for attachment to perforated walls, bolt elements having an L-shaped shank have the foot portions of their shanks entered into perforations of the wall and the supporting block for the shelf is bored to receive threaded ends of the bolt elements. Appropriate nuts are engaged to the bolt elements to secure the supporting block to the perforated wall and then the box-like shelf is slidably assembled over the supporting block.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
255 words
A shelf assembly comprising, in combination, a shelf member including rectangular first and second panels having generally flat and confronting surfaces, said shelf member including a third panel engaged to a first margin of each of said first and second panels, said shelf member including a fourth panel engaged to a second margin of each of said first and second panels and a fifth panel engaged to a third margin of each of said first and second panels, said third, fourth, and fifth panels cooperating to support the confronting surfaces of said first and second panels a first distance apart, a support member slidably received between said first and second panels and having opposite outer surfaces frictionally containing the confronting surfaces of said first and second panels, the confronting surfaces of said first and second panels each having an area larger than the area of the outer surface of said support member frictionally contacted thereto whereby said first and second panels have outer margins of their confronting surfaces spaced from said support member, said first and second panels being flexible, said outer surfaces of said support member spaced apart a second distance greater than said first distance, said first and second panels being flexed by entry of said support member between said first and second panels, the flexure of said first and second panels providing a restoring force to compressively grip said support member between said first and second panels, and means to affix said support member to one face of a vertically disposed wall.
Claim 2
Dependent Claim
255 words
A shelf assembly comprising, in combination, a shelf member including rectangular first and second panels having generally flat and confronting surfaces, said shelf member including a third panel engaged to a first margin of each of said first and second panels, said shelf member including a fourth panel engaged to a second margin of each of said first and second panels and a fifth panel engaged to a third margin of each of said first and second panels, said third, fourth, and fifth panels cooperating to support the confronting surfaces of said first and second panels a first distance apart, a support member slidably received between said first and second panels and having opposite outer surfaces frictionally containing the confronting surfaces of said first and second panels, the confronting surfaces of said first and second panels each having an area larger than the area of the outer surface of said support member frictionally contacted thereto whereby said first and second panels have outer margins of their confronting surfaces spaced from said support member, said first and second panels being flexible, said outer surfaces of said support member spaced apart a second distance greater than said first distance, said first and second panels being flexed by entry of said support member between said first and second panels, the flexure of said first and second panels providing a restoring force to compressively grip said support member between said first and second panels, and means to affix said support member to one face of a vertically disposed wall.
Claim 3
Dependent Claim
29 words
The shelf assembly of claim 1 including a one piece flexible sheet member adhered to one face of all of said first, second, third, and fourth, and fifth panels.
