Abstract
A directory casing comprising a base supporting an unbound stack of tab-indexed cards thereon, and a top cover pivotally coupled at its rear end to the base, with the tabs of the cards projecting forwardly out of the top cover. Upon manual depression of any selected tab, the top cover opens automatically with the card or cards overlying the card having the selected tab. In the directory casing of this general character, the invention provides means for holding the stack of cards in rearwardly declining disposition on the base, whereby when any selected tab is depressed, a comparatively great spacing is formed between the card having the selected tab and the overlying card or cards, and failure-proof opening of the top cover is assured.
Claims11
A directory casing comprising a base adapted to support on its top a stack of cards each having a tab projecting forwardly therefrom, said top of the base including a resiliently supported front end portion which is depressible by manual force exerted on any of the tabs of the cards thereon, a top cover pivotally coupled at its rear end to the base and adapted to be closed over the cards thereon so as to leave their tabs exposed, spring means biasing the top cover in an opening direction, engaging means for normally locking the top cover in a closed position against the bias of the spring means and, upon exertion of manual force on a selected one of the tabs, for permitting the top cover to open with the card or cards, if any, overlying the card having the selected tab, and stationary card-declining means provided on the top of the base and arranged rearwardly of the resiliently supported front end portion thereof to support the cards on the top of the base in rearwardly declining disposition, whereby upon exertion of manual force on a selected one of the tabs, a sufficient spacing can be formed between the front end portions of the card having the selected tab and the card lying immediately thereover.
