Abstract
A collapsible rack is disclosed which comprises a plurality of partition members which are pivotally joined together at their bases with linking members to form an expandable lazy tong structure. A plurality of guide means which are each secured to and integral with the linking members are provided for guiding stacks of sheets placed in the rack. The guide means define slanted guide surfaces which extend between the bases of adjacent partition members. The guide surfaces all have a substantially common orientation on the linking members. The guide means also serve the function of improving the rigidity of the structure, defining back-up surfaces that insure the proper support of the sheets and fan the sheets into oblique relationship with each other enabling convenient removal of the sheets.
