US Patent 7900783 Standard and track shelving systems

A shelving system is disclosed that includes two tracks and a standard. The standard has an end portion slidably receivable within an opening one of the tracks, such that the position of the standard relative to the track is slidably adjustable along that track. The rearward portion of each track defines a recess. An elongate member is slidably receivable within the recesses of the tracks such that each track is slidable along the elongate member, whereby the slidable engagement of the elongate member within the recesses of the tracks aligns the tracks and allows slidable adjustment of the relative positioning of the tracks to each other.
