  • Patent number: 4077520
    Abstract: A vertical storage rack for cards or the like comprises a casing means carried by the casing for forming a plurality of downwardly-extending pockets which overlap each other from front to back and have openings one above the other at the front of the rack and means for supporting the bottom edges of the cards in the pockets at levels which can be decided by the user either by adjusting the depths of the pockets or by inserting the cards against selected parts of the pocket. Preferably each pocket is formed of a sheet of flexible material the front edge of which is fixed and forms the bottom edge of the pocket opening and the rear edge of which is supported by adjusting means which can be operated to raise or lower the back of the pocket and thus adjust its depth. Vertical dividing members are movable between different positions along the pockets and divide the latter into individual pockets the width of which can be adjusted.
