Abstract
Abstract The invention relates to adjustable storage arrangements, such as racks, which may be readily erected and dismantled from a plurality of interconnectable, elongate shaped members comprising uprights and/or cross-pieces, at least some of which have substantially the same, open or channel cross-section, generally resembling a triple "sigma" contained within a rectangle. Trapezoidal re-entrant areas are provided on three sides of the said cross-sectional shape, and equidistant engagement apertures are situated in at least one line parallel to the longitudinal direction of each shaped member which comprises an upright, in the larger side of the upright opposite the open side thereof. Angle brackets are secured generally perpendicularly to the ends of the shaped members which form the cross-pieces, which brackets are capable of fitting round the front part, and either the right or left-hand part, respectively, of the triple-sigma-shaped upright. The brackets have projections which fit into the engagement apertures in the upright, and wedge the bracket against one of the side-walls of the upright when the cross-piece is moved downwardly relative to the upright.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
144 words
An arrangement for assembling uprights and cross-pieces which have substantially the same, open cross-sectional shape, said uprights being generally of sigma shape in cross-section, symmetrically facing each other and having in the arms and base of the sigma a generally V shaped re-entrant part or depression, having a flat portion at its apex, equidistant engagement apertures situated in at least one line parallel to the longitudinal direction of the upright in the base thereof opposite the opening, angle brackets secured generally perpendicularly to the ends of the cross-pieces which are capable of fitting round the front part, and one of the right or left-hand part of the upright, the said brackets having means to fit into the engagement apertures in the upright and to wedge the said bracket against one of the side-walls of the upright when the said cross-piece is translationally moved downwards.
Claim 2
Dependent Claim
144 words
An arrangement for assembling uprights and cross-pieces which have substantially the same, open cross-sectional shape, said uprights being generally of sigma shape in cross-section, symmetrically facing each other and having in the arms and base of the sigma a generally V shaped re-entrant part or depression, having a flat portion at its apex, equidistant engagement apertures situated in at least one line parallel to the longitudinal direction of the upright in the base thereof opposite the opening, angle brackets secured generally perpendicularly to the ends of the cross-pieces which are capable of fitting round the front part, and one of the right or left-hand part of the upright, the said brackets having means to fit into the engagement apertures in the upright and to wedge the said bracket against one of the side-walls of the upright when the said cross-piece is translationally moved downwards.
Claim 3
Dependent Claim
35 words
An arrangement according to claim 1, characterised in that the re-entrant area of the shaped members comprising the uprights or cross-pieces lies substantially along the major axis of a rectangle circumscribed about the cross-sectional shape.
Claim 4
Dependent Claim
36 words
An arrangement according to claim 1, characterised in that the re-entrant area of the shaped members comprising the uprights or cross-pieces lies substantially along the major axis of geometrical inertia or stability of the cross-sectional shape.
Claim 5
Dependent Claim
64 words
An arrangement according to claim 1, characterised in that the said line of engagement apertures is situated in the flat apex of said depression or reentrant area of the shaped members forming the uprights the said assembly brackets being secured to the ends of the cross-pieces and incorporating a plurality of lugs adapted to fit sideways into the said engagement apertures in an upright.
Claim 6
Dependent Claim
93 words
An arrangement according to claim 4, characterised in that the lugs on the brackets fixed to the cross-pieces are cut out to form hooks, the upper part of which is vertical and the lower part of which slopes by a few degrees, the upper parts of the engagement apertures in the uprights being of constant width and the lower parts being of decreasing width, the said hooks leaving a slot between themselves and the bodies of the brackets, the width of which decreases until it equals the cross-sectional thickness of the shaped members.
Claim 7
Dependent Claim
62 words
An arrangement according to claim 1, characterised by two lines of engagement apertures situated in the two flat surfaces on either side of the re-entrant area or depression of the base of the sigma cross-sectional shape of the uprights, the said assembly brackets welded to the ends of the cross-pieces being provided with studs adapted to fit into the said engagement apertures.
Claim 8
Dependent Claim
41 words
An arrangement according to claim 6, characterized in that the said studs comprise a body and a head, the said heads projecting from the said brackets by an amount at least equal to the thickness of the metal of the upright.
Claim 9
Dependent Claim
58 words
An arrangement according to claim 6, characterised in that the said vertically aligned engagement apertures are formed by an upper part suitable to receive the head of the stud and a lower part, the width of which decreases to a size less than the diameter of the head and greater than that of the body of the stud.
Claim 10
Dependent Claim
60 words
An arrangement according to claim 8, further characterised in that the said engagement apertures have, in their lower part, an edge which is inclined to the vertical and which is operable to urge the body of the stud sideways until the said angle bracket is wedged against the side-wall of the upright when the said cross-piece is translationally moved downwards.
