Abstract
Abstract A rope-suspended shelving unit wherein a plurality of generally rectangular shelves each of which has a front and rear edge are provided with first holes respectively in the four corners or only in the rear two corners. A second hole is substantially in the middle between one of the rear holes and either the respective front hole or the front edge. A third hole is substantially in the middle between the second hole and the respective front hole or front edge. The holes are adapted so that a rope, chain, cable or the like can pass through them so as to maintain the shelves in layered relationship at predetermined yet adjustable intervals. An elastic stabilizer is arranged on the part of the rope or the like in contact with the rear edge of the shelf so that the rope is fixed on the back side of the shelf in the lowermost step so that no receiving metal fixture is required and the formation is simple and stable in contact with the wall. An elastic bushing is affixed in the holes to further prevent slippage of the rope in contact with the shelves.

Claim 1
Independent Claim
221 words
A suspended shelving unit for hanging a set of shelves downwardly along a wall from a hook assembly at adjustable spacing intervals comprising in combination, at least two shelves each having an edge disposable away from said wall and a wall engaging edge and defining a first set of apertures for receiving a first flexible line at the wall engaging edges and a second set of apertures for receiving a second line at the edge away from said wall, a first line fed through the first apertures at the wall engaging edges and looped about the shelf edge at each aperture to support and space the shelves a predetermined distance apart forming a generally parallel relationship to the wall, a second flexible line fed through the second set of apertures and looped about the shelf edge at each edge away from said wall to support and space the shelves said predetermined distance apart, a hook assembly engaging both lines at their uppermost extremities with said second line defining an acute angle with said wall toward the uppermost shelf thereby to provide a force by weight of the shelves on said second line tending to hold the shelves against the wall, whereby the loops of said flexible lines about said shelves may be rearranged to change said predetermined distance between adjacent shelves.
Claim 2
Dependent Claim
221 words
A suspended shelving unit for hanging a set of shelves downwardly along a wall from a hook assembly at adjustable spacing intervals comprising in combination, at least two shelves each having an edge disposable away from said wall and a wall engaging edge and defining a first set of apertures for receiving a first flexible line at the wall engaging edges and a second set of apertures for receiving a second line at the edge away from said wall, a first line fed through the first apertures at the wall engaging edges and looped about the shelf edge at each aperture to support and space the shelves a predetermined distance apart forming a generally parallel relationship to the wall, a second flexible line fed through the second set of apertures and looped about the shelf edge at each edge away from said wall to support and space the shelves said predetermined distance apart, a hook assembly engaging both lines at their uppermost extremities with said second line defining an acute angle with said wall toward the uppermost shelf thereby to provide a force by weight of the shelves on said second line tending to hold the shelves against the wall, whereby the loops of said flexible lines about said shelves may be rearranged to change said predetermined distance between adjacent shelves.
Claim 3
Dependent Claim
24 words
A shelving unit as defined in claim 1 wherein said second flexible line is looped about the shelf edge disposable away from said wall.
Claim 4
Dependent Claim
34 words
A shelving unit as defined in claim 1 having an elastic stabilizer member disposed on said wall engaging edge encompassing said line and providing increased friction against lateral movement of shelves against said wall.
Claim 5
Dependent Claim
16 words
A shelving unit as defined in claim 1 wherein said stabilizer member encompasses said first line.
Claim 6
Dependent Claim
25 words
A shelving unit as defined in claim 3 secured to the wall solely at said hook assembly, with said shelves suspended therefrom by said lines.
Claim 7
Dependent Claim
21 words
A shelving unit as defined in claim 1 having elastic bushings disposed within each aperture to receive the respective lines therethrough.
Claim 8
Dependent Claim
41 words
A shelving unit as defined in claim 1 wherein the second flexible line from said first shelf to the second shelf is disposed at an acute angle to said wall to thereby urge the lowermost shelf toward contact with said wall.
Claim 9
Dependent Claim
22 words
A shelving unit as defined in claim 5 wherein the two shelves have differing widths and the wider shelf is disposed lowermost.
Claim 10
Dependent Claim
37 words
A shelving unit as defined in claim 1 wherein the second set of apertures comprises at least two apertures through which the line is looped for supporting the edge of each shelf disposable away from said wall.
Claim 11
Dependent Claim
40 words
A shelving unit as defined in claim 1 wherein both said lines are extended through the bottommost shelf, and resilient means below the bottommost shelf engaging both the respective two lines and biasing the respective two lines toward each other.
