Abstract
Abstract Shelving consists of at least two juxtaposed shelf units which include frame members, such as vertical posts, of metal profiled sections, together with floor and/or roof members. The shelf units are connected by sheet metal clips whose ends are bent over to engage wedge-shaped converging edges on the sections or floors or roofs, each clip being formed with a bead extending transversely across the clip and projecting on the opposite side to the bent-over ends. The bead is offset from the centre of the clip so that it lies wholly within one of the two shelf units connected by the clip, leaving the other unit clear for accommodating a common side wall extending to the frame members and the roof of the unit. Identical clips are used to connect the posts, which have a G-shaped cross-section, with vertical walls having U-section flanged edges. A rear wall with cranked edges can also be slotted into the apertures in the G-section posts.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
175 words
In shelving having at least a pair of juxtaposed shelf units, said units each having upright frame members and at least floor and roof members secured to the respective ones of said frame members of each of said units, the improvement comprising: a plurality of resilient clip means for securing one of said floor and roof members in one of said units to the other of said floor and roof members in a closely adjacent other one of said units, each of said clip means consisting of a pair of flat and coplanar strips of unequal length connected by a bead so that said bead is offset from the center of the combined length of said pair of strips, the ends of strips remote from said bead being bent to form bent-over ends, said bent-over ends of said strips engaging one of said roof and floor members in each of said units to hold said units together and to prevent a separation thereof, said bead being positioned offset from the parting line between said units.
Claim 2
Dependent Claim
175 words

Claim 3
Dependent Claim
68 words
The improvement according to claim 1, including wall means defining a common wall between said pair of units, said wall means being aligned with the frame members in one of said units on a side of said parting line opposite from said bead whereby said wall means are permitted to closely abut the edges of at least one of said floor and said roof of said one unit.
Claim 4
Dependent Claim
36 words
The improvement according to claiM 1, wherein said bent-over ends are bent at an angle greater than 90* and said bead projects from the plane of said strips in a direction opposite to said bent-over ends.
Claim 5
Dependent Claim
80 words
The improvement according to claim 2, wherein said upright frame members consist of vertically extending elongated and hollow posts having a vertical aperture therein; wherein at least one edge of said wall means consists of a U-shaped cross section at least closely adjacent one of said vertical posts, said bent-over ends of said clip means engaging an edge of said vertical aperture and a leg of said U-shaped edge to hold said units together and to prevent a separation thereof.
Claim 6
Dependent Claim
58 words
The improvement according to claim 2, wherein edges of said roof and floor members consist of a U-shaped cross section, said U-shaped edges being aligned with at least one of said upright frame members, said bent-over ends engaging an edge of each of the adjacent U-shaped edges of said roof and floor members of said pair of units.
Claim 7
Dependent Claim
15 words
The improvement according to claim 4, wherein said vertically extending posts have a G-shaped cross-section.
Claim 8
Dependent Claim
59 words
The improvement according to claim 4, including means defining a rear wall and intermediate compartment floors for each of said units, said rear wall being cranked along at least one vertical edge, said vertical edge being received in said vertical aperture while the inner surface of said rear wall lies against the rear edges of said intermediate compartment floors.
