  • Patent number: 4232918
    Abstract: This invention relates to an improved suspension system for filing computer paper vertically in a file drawer or cabinet. A bundle of a desired number of sheets of paper may be filed using a system having a pair of assemblies, each of which has two members to engage the upper corners of the sheets of paper. The first member of each assembly has a flat panel-like portion which extends at an upper corner thereof to define a downwardly open hook and three vertically spaced horizontally extending prongs. The second member is flat and rectangular shaped and has three vertically spaced apertures which mate to receive the three prongs therethrough. The prongs of each first member are inserted through the upper three holes along one side of the computer paper, and the second member is then located on the prongs. This is repeated on the other side with the other assembly to hold the sheets of paper in a single bundle.
