  • Vertical card file
    Patent number: 6095625
    Abstract: A file for storing and displaying cards is disclosed. The card file consists of a base, a cover, and a tray, the cover being pivotally attached to the base and the tray being slidably disposed with respect to the cover and pivotally coupled to the base. The tray is attached to the base in such a way that when the cover is opened, the tray pivots downwardly, thereby presenting the cards at an angle. The weight of the address cards keeps the device in either the open or closed orientation chosen by the user. The card file in accordance with the present invention can be suitably adapted to display a picture or time keeping instrument in the face of the cover, so that when the cards are concealed, the card file serves as an office accessory.
