Abstract
Abstract A shelf mountable on vertical support members is made of a rectangular piece of sheet metal and is provided with truncated corners. A flange extends around the periphery of the shelf including the regions of the truncated corners to reinforce the shelf. Connector members are clamped to the flange at the truncated corners and are adapted for mounting on the vertical support members. Spaced parallel ribs substantially extend between one pair of opposing edges of the shelf and are parallel to the other pair of edges. A row of elongate rectangular apertures is provided between each pair of spaced parallel ribs. The rows have lengths substantially corresponding to those of the ribs. In this manner, objects placed on the ribs are maintained at a level above the surface of the shelf and air is permitted to pass through the apertures and circulate around the objects including along the supported surfaces thereof. The ribs reinforce the shelf in the regions weakened by the apertures.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
264 words
A shelf mountable on a shelf support structure, said shelf comprising a substantially flat, one-piece rectangular sheet of material having downwardly depending corner portions, said corner portions at each corner being disposed in a plane substantially normal to a plane defined by said flat sheet; connector means on said sheet for mounting said shelf on the support structure, said connector means including corner connectors at each corner, each connector including a corner structure disposed on one side of a respective corner portion and a clamping bar disposed on an 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, surfaces of said corner structure and clamping bar being substantially complementary to each other; 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, each corner connector defining a substantially closed crevice-free structure which houses a corner portion; a plurality of spaced protuberances projecting above one major surface of said sheet; and a plurality of apertures provided between said spaced protuberances, whereby objects placed on said protuberances are maintained at a level above said one major surface and air is permitted to pass through said apertures and circulate around the objects including along supported surfaces thereof.
Claim 2
Dependent Claim
264 words
A shelf mountable on a shelf support structure, said shelf comprising a substantially flat, one-piece rectangular sheet of material having downwardly depending corner portions, said corner portions at each corner being disposed in a plane substantially normal to a plane defined by said flat sheet; connector means on said sheet for mounting said shelf on the support structure, said connector means including corner connectors at each corner, each connector including a corner structure disposed on one side of a respective corner portion and a clamping bar disposed on an 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, surfaces of said corner structure and clamping bar being substantially complementary to each other; 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, each corner connector defining a substantially closed crevice-free structure which houses a corner portion; a plurality of spaced protuberances projecting above one major surface of said sheet; and a plurality of apertures provided between said spaced protuberances, whereby objects placed on said protuberances are maintained at a level above said one major surface and air is permitted to pass through said apertures and circulate around the objects including along supported surfaces thereof.
Claim 3
Dependent Claim
18 words
A shelf as defined in claim 1, wherein said flat sheet of material is made from sheet metal.
Claim 4
Dependent Claim
42 words
A shelf as defined in claim 1, wherein said corner portions are truncated, said sheet being provided with a peripheral flange extending substantially around an entire periphery of said sheet including in regions of said truncated corner portions to reinforce said sheet.
Claim 5
Dependent Claim
16 words
A shelf as defined in claim 1, wherein said protuberances comprise a plurality of spaced ribs.
Claim 6
Dependent Claim
28 words
A shelf as defined in claim 4, wherein said ribs substantially extend between one pair of opposing edges and are parallel to the other pair of opposing edges.
Claim 7
Dependent Claim
18 words
A shelf as defined in claim 4, wherein said spaced ribs are straight and parallel to each other.
Claim 8
Dependent Claim
22 words
A shelf as defined in claim 6, wherein said apertures comprise a row of spaced apertures between each two spaced parallel ribs.
Claim 9
Dependent Claim
44 words
A shelf as defined in claim 7, wherein each aperture is substantially rectangular and has dimensions of the same order of magnitude as the spacing between two ribs, whereby the spaces between adjacent ribs are substantially open to maximize the amount of ventilation therethrough.
Claim 10
Dependent Claim
28 words
A shelf as defined in claim 7, wherein said ribs and rows of apertures are straight and each parallel to one pair of opposing edges of said sheet.
Claim 11
Dependent Claim
30 words
A shelf as defined in claim 9, wherein said ribs and rows of apertures are approximately the same length and each substantially extend between the other pair of opposing edges.
