Abstract
Abstract The invention relates to an article supporting assembly that is useful as a toolbox, for shelving, for article display purposes, and a wide variety of other purposes. The basic assembly includes a center plate, at least two spanners, each having first and second opposite edges, at least two cover plates, and article supporting structures formed on the center plate and the cover plates. Each of the spanners is hinged to the center plate generally along the first spanner edges, the cover plates are hinged together, and each cover plate is hinged to a spanner generally along the second edge of the spanner, so that the cover plates are pivotal from a first position generally parallel to the center plate (spaced the width of the spanner) to a second position generally perpendicular to the center plate. A casing preferably surrounds the center plate, with a handle formed on the casing. Two sets of spanners and cover plates may be provided, one on each side of the center plate, and the center plate may be mounted on the casing for rotational movement.

Claim 4
Dependent Claim
15 words
An assembly as recited in claim 2 wherein said attaching means comprise a permanent magnet.
Claim 5
Dependent Claim
31 words
An assembly as recited in claim 1 further comprising casing means for covering the space between said cover plates and center plate when said cover plates are in said first position.
Claim 6
Dependent Claim
64 words
An assembly as recited in claim 4 wherein said casing means comprise a housing generally quadrate in plan, and including top, bottom, and two side portions, with two open end portions generally corresponding to said cover plates and said center plate; and wherein said housing top, bottom, and two side portions have a width at least as large as the width of said spanners.
Claim 7
Dependent Claim
45 words
An assembly as recited in claim 5 further comprising releasable holding means for holding said cover plates to said casing means so that said cover plates are immobile with respect to said casing means and said center plate while said releasable holding means are activated.
