Shelving unit

Claim 1

A shelving unit comprising a base, at least one upright, and a plurality of shelves mountable thereon: in which each shelf has at least one bracket with rearwardly extending tabs for engagement with shelf-retaining slots in the upright; in which the upright comprises a lower vertically elongated member extending upwardly from the base, and an upper vertically elongated member in telescoping relationship with the lower member, at least part of the upper member extending upwardly from the upper end of the lower member, means for preventing relative horizontal movement of the upper and lower members, and means for selectably supporting the upper member in each of a plurality of heights on the lower member; in which the lower member comprises an elongated, oblique sheet metal web having a face side and a back side and a first series of shelf-retaining slots, each slot extending through the web from the face side to the back side, said first series extending in a line downwardly along said oblique sheet metal web from a location adjacent to the upper end thereof; in which the upper member comprises an elongated vertical sheet metal web constituting the front side thereof, the web having a face side and a back side the face side having a first planar surface and a second planar surface, the second planar surface being spaced rearwardly and located to one side of the first planar surface, and having a second series of shelf-retaining slots each slot extending from the face side of the second planar surface to the back side of the web, the second series of slots being arranged in a vertical line positioned directly to the rear of the line of said first series of slots; and in which, at least at the upper end of the lower member, the back side of the elongated sheet metal web of the lower member is in such close proximity to the face side of the sheet metal web of the upper member that if one of said shelves is positioned at the uppermost end of the lower member, with a tab extending through the uppermost shelf-retaining slot in the lower member, the tab extends through the plane of said first planar surface, and the spacing between the planes of the first and second planar surfaces being such that said tab does not reach said second planar surface.
