Abstract
Abstract A display stand, made entirely of corrugated fiberboard as the preferred material, which may be shipped with all component parts in a flat or knock-down position. The legs of the display stand are pre-cut and pre-formed in a unique mechanical design so that they may be simply assembled using a roll-up method without the need for tools or fasteners. Once assembled, the legs form a telescoping design whereby they may be interfitted with each other and with cooperating shelves to provide a multi-shelf display stand which, although made of light-weight materials to reduce shipping costs, is extremely sturdy in use.

Claim 1
Independent Claim
380 words
A leg assembly for a telescoping display stand wherein said leg assembly comprises, a first lower zone (80), said first lower zone (80) having a plurality of sections formed therein via vertical score lines (20), at least one tab (30) formed on an outer section (11) of said first lower zone, wherein one of the sections of said first lower zone (80) has at least one slot (40) formed therein, said slot (40) being formed at the same level as said tab (30), a second upper zone (90) attached to said first lower zone (80) via a vertical score line (20), said second upper zone (90) extending substantially above said first lower zone (80), said second upper zone (90) having a plurality of sections formed therein via vertical score lines (20), wherein one of the sections of said second upper zone (90) has at least one slot (50) formed therein, said slot (50) being formed at the same level as said tab (30) and said slot (40), means for manually rolling said leg assembly along said vertical score lines (20) such that said at least one slot (40) in said first lower zone (80) overlies said at least one slot (50) in said second upper zone (90), means whereby said plurality of sections are formed such that said at least one tab (30) may be inserted into said slots (40, 50) to thereby retain the leg in a locked position ready for use, means whereby upon being in said locked position a ledge (70) is formed between said first lower zone (80) and said second upper zone (90), said ledge (70) being formed around the entire periphery of said leg assembly when in its locked position, wherein said leg assembly is comprised entirely of corrugated fiberboard material and requires no separate fastener elements, wherein said plurality of sections of said second upper zone (90) are of reduced width relative to said plurality of sections in said first lower zone (80) to provide means whereby said second upper zone, upon assembly, may be slidably and securely received into a first lower zone of another identical leg assembly, wherein said second upper zone (90) is positioned laterally of said first lower zone (80) when said leg assembly is in its flattened position.
Claim 2
Dependent Claim
380 words
A leg assembly for a telescoping display stand wherein said leg assembly comprises, a first lower zone (80), said first lower zone (80) having a plurality of sections formed therein via vertical score lines (20), at least one tab (30) formed on an outer section (11) of said first lower zone, wherein one of the sections of said first lower zone (80) has at least one slot (40) formed therein, said slot (40) being formed at the same level as said tab (30), a second upper zone (90) attached to said first lower zone (80) via a vertical score line (20), said second upper zone (90) extending substantially above said first lower zone (80), said second upper zone (90) having a plurality of sections formed therein via vertical score lines (20), wherein one of the sections of said second upper zone (90) has at least one slot (50) formed therein, said slot (50) being formed at the same level as said tab (30) and said slot (40), means for manually rolling said leg assembly along said vertical score lines (20) such that said at least one slot (40) in said first lower zone (80) overlies said at least one slot (50) in said second upper zone (90), means whereby said plurality of sections are formed such that said at least one tab (30) may be inserted into said slots (40, 50) to thereby retain the leg in a locked position ready for use, means whereby upon being in said locked position a ledge (70) is formed between said first lower zone (80) and said second upper zone (90), said ledge (70) being formed around the entire periphery of said leg assembly when in its locked position, wherein said leg assembly is comprised entirely of corrugated fiberboard material and requires no separate fastener elements, wherein said plurality of sections of said second upper zone (90) are of reduced width relative to said plurality of sections in said first lower zone (80) to provide means whereby said second upper zone, upon assembly, may be slidably and securely received into a first lower zone of another identical leg assembly, wherein said second upper zone (90) is positioned laterally of said first lower zone (80) when said leg assembly is in its flattened position.
Claim 3
