Patent ID: 8025165

Claim:
A rack system comprising: a storage rack frame comprising: at least four spaced apart uprights, each residing approximately vertically and forming a rectangle; and at least two pairs of lateral beams longitudinally spaced apart and approximately parallel, the at least two pair of lateral beams supported by the uprights and defining an approximately horizontal plane; lateral tracks supported by the lateral beams; at least two rows of bins comprising: at least one row of forward bins slidably cooperating with the lateral tracks to allow lateral movement of the forward bins within each of their respective rows; and a row of rear bins residing behind the at least one row of forward bins and supported by the lateral beams, wherein the sum of the widths W 1 of the forward bins in each of the at least one row and the widths W 1 of the individual forward bins are selected to allow access to the rear bins by laterally sliding adjacent forward bins apart, and wherein the rear bins slidably cooperate with longitudinal tracks to slide the rear bins forwards and rearwards in a direction orthogonal to the lateral movement of the forward bins.
