Abstract

Abstract The shelf assembly described herein comprises a shelf arrangement designed for assembly by sliding in a limited manner doweled or tubed component parts into interlocking arrangement from the rear of the assembly. This has the advantages of a locked arrangement once the assembly is fastened to the back of a door and allows for greater structural strength and improved appearance of the front of the assembly.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 407 words
A shelving assembly comprising: (a) a plurality of side panels of rectangular shape having attached at their linear ends either element of a dowel-tube arrangement, the outer configuration of said dowel conforming in size and shape to fit closely inside the opening in said tube, said side panels comprising two sets of a top panel, a bottom panel and at least one intermediate panel, the top and bottom side panels of said assembly having only one of said elements and the intermediate said panels having two of said elements so arranged as to be fitted to and interlocked with its opposite element in the adjacent side panel, said side panel also having a slit running perpendicular to the length of said side panel and extending from the rear edge of said side panel to at least half but not more than 0.9 of the width of said panel, and each said side panel having a flange affixed to the back linear edge of said side panel and extending perpendicularly therefrom and adapted to be fastened to a vertical door or wall area, said flange having an opening positioned at and communicating with the said slot extending part way through the width of said side panel, said opening being enlarged with respect to the width of said slot and adapted to receive a dowel element, and said flange being of appropriate length and positioned close to the adjacent end of any said doweled element attached to the corresponding side panel that it would extend over a portion of the tube element thereby preventing the dowel of the doweled element from sliding any further into the opening of said tube element and also thereby requiring the doweled member to be introduced from the opposite end into the opening of the tube member; and (b) a plurality of shelf elements comprising a rigid rectangular sheet or platform having a doweled element attached along the edge of each of the linear ends thereof, said doweled element being adapted to fit through the said opening in said flange and the end of said sheet to which said doweled element is attached being of an appropriate thickness to fit into one of said slots in said side panels, the width of the said rectangular sheet at the edge to which said doweled element is attached being only of appropriate dimension to extend the full length of the slot into which it is inserted.
Claim 2
Dependent Claim 407 words
A shelving assembly comprising: (a) a plurality of side panels of rectangular shape having attached at their linear ends either element of a dowel-tube arrangement, the outer configuration of said dowel conforming in size and shape to fit closely inside the opening in said tube, said side panels comprising two sets of a top panel, a bottom panel and at least one intermediate panel, the top and bottom side panels of said assembly having only one of said elements and the intermediate said panels having two of said elements so arranged as to be fitted to and interlocked with its opposite element in the adjacent side panel, said side panel also having a slit running perpendicular to the length of said side panel and extending from the rear edge of said side panel to at least half but not more than 0.9 of the width of said panel, and each said side panel having a flange affixed to the back linear edge of said side panel and extending perpendicularly therefrom and adapted to be fastened to a vertical door or wall area, said flange having an opening positioned at and communicating with the said slot extending part way through the width of said side panel, said opening being enlarged with respect to the width of said slot and adapted to receive a dowel element, and said flange being of appropriate length and positioned close to the adjacent end of any said doweled element attached to the corresponding side panel that it would extend over a portion of the tube element thereby preventing the dowel of the doweled element from sliding any further into the opening of said tube element and also thereby requiring the doweled member to be introduced from the opposite end into the opening of the tube member; and (b) a plurality of shelf elements comprising a rigid rectangular sheet or platform having a doweled element attached along the edge of each of the linear ends thereof, said doweled element being adapted to fit through the said opening in said flange and the end of said sheet to which said doweled element is attached being of an appropriate thickness to fit into one of said slots in said side panels, the width of the said rectangular sheet at the edge to which said doweled element is attached being only of appropriate dimension to extend the full length of the slot into which it is inserted.
Claim 3
Dependent Claim 27 words
The shelving assembly of claim 1 in which each said shelf element has a flange extending vertically upward from the front linear edge of said rectangular sheet.
Claim 4
Dependent Claim 28 words
The shelving assembly of claim 2 in which each said shelf element also has a flange extending vertically upward from the back linear edge of said rectangular sheet.
Claim 5
Dependent Claim 27 words
The shelving assembly of claim 1 in which each said shelf element has a flange extending vertically upward from the back linear edge of said rectangular sheet.
Claim 6
Dependent Claim 49 words
The shelving assembly of claim 1 in which each said dowel element is cylindrical in shape except for the portion attached to said side panel and the opening in each said tube element corresponds in size and cylindrical shape to accommodate a snug fit of the dowel element therein.
Claim 7
Dependent Claim 40 words
The shelving assembly of claim 1 in which said tube element of said side panel extends only to the inside surface of said flange attached to said side panel whereby the flanges on said adjacent side panels are thereby aligned.
Claim 8
Dependent Claim 63 words
The shelving assembly of claim 1 in which said assembly includes at the top thereof a back support member having two side arms extending perpendicularly forward therefrom and having attached to each of said side arms a doweled member in a manner similar to that described for said shelf elements, and said back support member having a plurality of pegs extending forward therefrom.
