Abstract
Abstract A shelf has a generally rectangular planar member having truncated corners. The planar member is provided with peripheral skirts which extend substantially normally to the plane defined by the planar member. The portions of the skirts in the regions of the truncated corners define support flanges when the planar member comprises a sheet metal member. When the planar member comprises a wire grid, the support flange comprises upper and lower sets of peripheral wires which are diagonally bent and form extensions extending about the corners of the planar member. The support flanges extend substantially normally to the plane defined by the planar member. A corner connector has a corner structure adapted to be mounted on a post structure and to at least partially receive a respective support flange. A clamping bar is positioned on the other side of a support flange relative to an associated corner structure. Screws are utilized to draw the corner structure and clamping bar together with a respective support flange positioned therebetween.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
183 words
A shelf comprising a generally rectangular one piece planar member having downwardly depending corner portions, said corner portions at each corner being disposed in a plane substantially normal to the plane defined by said planar member; corner connectors at each corner, each connector comprising a corner structure disposed on one side of a respective corner portion and a clamping bar disposed on the opposing side of the respective corner portion, at least one of said corner structure and clamping bar being provided with a recess dimensioned to receive a corner portion when the latter is clamped between an associated corner structure and clamping bar, the surfaces of said corner structure and clamping bar being substantially complementary to each other; and fastening means for maintaining each corner structure and associated clamping bar in abutment against each other and against a respective corner portion with the latter being received within the respective recess, said corner structures further being provided with means for mounting the same on a shelf support post, whereby each corner connector forms a substantially closed crevice-free structure which houses a corner portion.
Claim 2
Dependent Claim
183 words
A shelf comprising a generally rectangular one piece planar member having downwardly depending corner portions, said corner portions at each corner being disposed in a plane substantially normal to the plane defined by said planar member; corner connectors at each corner, each connector comprising a corner structure disposed on one side of a respective corner portion and a clamping bar disposed on the opposing side of the respective corner portion, at least one of said corner structure and clamping bar being provided with a recess dimensioned to receive a corner portion when the latter is clamped between an associated corner structure and clamping bar, the surfaces of said corner structure and clamping bar being substantially complementary to each other; and fastening means for maintaining each corner structure and associated clamping bar in abutment against each other and against a respective corner portion with the latter being received within the respective recess, said corner structures further being provided with means for mounting the same on a shelf support post, whereby each corner connector forms a substantially closed crevice-free structure which houses a corner portion.
Claim 3
Dependent Claim
16 words
A shelf as defined in claim 1, wherein said planar member comprises a sheet metal member.
Claim 4
Dependent Claim
16 words
A shelf as defined in claim 1, wherein said planar member comprises a wire grid member.
Claim 5
Dependent Claim
47 words
A shelf as defined in claim 1, wherein said planar member comprises a sheet metal member provided with a peripheral bead, said corner connectors comprising clamping means having a clamping bar a portion of which is configurated to mate interiorly of said bead in a complementary manner.
Claim 6
Dependent Claim
60 words
A shelf as claimed in claim 1, wherein said planar member comprises a wire grid, said corner portions comprising wire portions diagonally oriented relative to the sides of said planar member, said corner connectors comprising clamping means having grooves formed therein for receiving said wire portions in pressure fit relation when said corner connectors are mounted on said planar member.
Claim 7
Dependent Claim
70 words
A shelf as claimed in claim 1, wherein each of said means for mounting said corner structures is provided with a tapered bore, and further comprising complementary tapered sleeves receivable in said bores, said sleeves being adjustably movable on the support post, whereby the positions of said corner connectors can be adjusted along the post by moving the sleeves on the post and supporting said corner connectors on said sleeves.
Claim 8
Dependent Claim
28 words
A shelf as defined in claim 1, wherein said planar member has truncated corners, and said corner portions each extend across a truncated corner of said planar member.
