Abstract

Abstract A pre-assembled array of corner shelves is fastened together by three flexible lines threaded through apertures in the shelves so that they can hang downwardly from a single hook mounted in the corner between two intersecting walls. The lines are so disposed to form an acute angle with the corner line toward the frontmost edge of the shelf disposed in the corner, thereby to force the shelf against the corner and adjacent walls by its own weight and that of objects on it to support the structure and prevent it from slipping or sliding. The spacing may be rearranged simply by moving the lines and the shelves may be readily leveled in the same manner. The shelf array is simply removed for cleaning walls or the shelves without loosening any mounting hardware.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 215 words
A shelf array suspendable from a single hook for disposal in a corner location adjacent two intersecting walls, comprising in combination, at least one shelf generally triangular in shape having defined therein near an edge along two sides and in triangular corner therebetween a series of apertures, a flexible line array comprising three flexible lines arrayed in three parts respectively through the apertures in the corner and the apertures along the two adjacent edges respectively with loops through the shelf in all three lines to thereby support it in a changeable position that is movable to level the shelf or to adjust spacing of the shelf against the wall, holding means comprising a ring member surrounding all three lines adjacent the corner location and a securing member adjacent thereto securing an uppermost one end of one of the three lines to retain the line through the corner aperture substantially parallel to the intersection of the walls when hanging and to dispose the other two lines toward an uppermost shelf at an acute angle away from the corner respectively to the foremost aperture along the two edges thereby to cause the weight of the shelf and any contents thereon to be urged toward the corner for contact with the walls adjacent thereto for support and stability.
Claim 2
Dependent Claim 215 words
A shelf array suspendable from a single hook for disposal in a corner location adjacent two intersecting walls, comprising in combination, at least one shelf generally triangular in shape having defined therein near an edge along two sides and in triangular corner therebetween a series of apertures, a flexible line array comprising three flexible lines arrayed in three parts respectively through the apertures in the corner and the apertures along the two adjacent edges respectively with loops through the shelf in all three lines to thereby support it in a changeable position that is movable to level the shelf or to adjust spacing of the shelf against the wall, holding means comprising a ring member surrounding all three lines adjacent the corner location and a securing member adjacent thereto securing an uppermost one end of one of the three lines to retain the line through the corner aperture substantially parallel to the intersection of the walls when hanging and to dispose the other two lines toward an uppermost shelf at an acute angle away from the corner respectively to the foremost aperture along the two edges thereby to cause the weight of the shelf and any contents thereon to be urged toward the corner for contact with the walls adjacent thereto for support and stability.
Claim 3
Dependent Claim 24 words
A shelf array as defined in claim 1 wherein a plurality of shelves are disposed in parallel spaced relationship by said flexible line array.
Claim 4
Dependent Claim 94 words
An array as defined in claim 2 wherein the apertures along the edges includes a foremost aperture near a corner and a further aperture spaced between two corners and the lines are fed from a topmost shelf to a lower shelf at an acute angle defined by the passage of the line from the further aperture of the upper shelf to the foremost aperture of a lower shelf thereby providing a force from weight of the lower shelf and any contents thereon urging that shelf into supporting contact with the walls adjacent the corner.
Claim 5
Dependent Claim 51 words
A shelf array as defined in claim 2 wherein the flexible lines are passed through a lowermost shelf and biasing means below the lowermost shelf flexibly engaging the ends of the three lines with a common spring array to take up slack and permit relative longitudinal movement of any individual line.
