Abstract

Abstract A shelf has a platform suspended by at least three cords or other flexible suspension means. The upper ends of the cords are gathered in a knot formed with a loop for suspension from a hook. The lower ends of the cords are attached to the platform, two of these cords being attached at, or near, the opposite ends of the side of the platform which, in one use of the shelf, is located near a wall. A slide similar to a bead receives the latter two cords. When the shelf is suspended from a hook located remote from a wall the bead is slid up to the knot and, since the cords are of the same length, the platform is horizontal. If the point of suspension is on or close to a wall, the bead is slid downwards to reduce the straight-line distance between the points of attachment to the platform and the knot. the position of the bead is adjusted so that the platform is horizontal (or at some desired slope).

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 172 words
In a shelf combination, a platform, at least three cords, the lower ends of said cords attached to said platform at widely spaced-apart positions on said platform to suspend said platform, means joining together the upper ends of each of said cords and having a loop for attachment to a hook or other suspension, and a slider manually slidable along only two of said cords between an upper location and a lower location to adjust the effective lengths of said two said cords to adjust the angle of said platform to the horizontal when said shelf is suspended by said loop, said slider comprising a bead formed with a bore, said two cords extending through said bore, the friction between said two cords and said bore holding said bead in a position of adjustment, said platform being formed with holes at said spaced positions, the lower ends of said cords passing through said holes, and fastened below said platform, said attachment of said cords to said platform being independent of said slider.
Claim 2
Dependent Claim 172 words
In a shelf combination, a platform, at least three cords, the lower ends of said cords attached to said platform at widely spaced-apart positions on said platform to suspend said platform, means joining together the upper ends of each of said cords and having a loop for attachment to a hook or other suspension, and a slider manually slidable along only two of said cords between an upper location and a lower location to adjust the effective lengths of said two said cords to adjust the angle of said platform to the horizontal when said shelf is suspended by said loop, said slider comprising a bead formed with a bore, said two cords extending through said bore, the friction between said two cords and said bore holding said bead in a position of adjustment, said platform being formed with holes at said spaced positions, the lower ends of said cords passing through said holes, and fastened below said platform, said attachment of said cords to said platform being independent of said slider.
Claim 3
Dependent Claim 26 words
The combination of claim 1 in which the number of said cords is four and said spaced positions are located at the corners of a Rectangle.
Claim 4
Dependent Claim 27 words
The combination of claim 1 in which the number of said cords is three and said spaced positions are located at the corners of an isosceles triangle.
Claim 5
Dependent Claim 23 words
The combination of claim 1 in which said means joining together said upper ends of said cords is a knot of said cords.
