Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
168 words
A card file comprising a tray structure, and control means for effecting selective fanned separation of cards and the like within said tray, said control means comprising a pair of elongated pleated strip members and means supporting the strip members for disposing the same at positions spaced upwardly from the bottom of said tray and disposed along opposite sides thereof, the pleats of said strip members being resiliently urged apart and adapted to receive and separate individual cards between said pleats with the pleats maintaining the cards in substantially parallel array and in transverse edgewise alignment and being of sufficient inherent resiliency to normally tend to open up with included cards, means being provided for holding the cards relatively together at their bottoms, whereby the cards are separated at their tops by said strip members under the resilient urging of said pleats sufficient to maintain the cards in one area selectively fanned without skewing thereof for ease of viewing relative to cards in another area of the tray.
Claim 2
Dependent Claim
168 words
A card file comprising a tray structure, and control means for effecting selective fanned separation of cards and the like within said tray, said control means comprising a pair of elongated pleated strip members and means supporting the strip members for disposing the same at positions spaced upwardly from the bottom of said tray and disposed along opposite sides thereof, the pleats of said strip members being resiliently urged apart and adapted to receive and separate individual cards between said pleats with the pleats maintaining the cards in substantially parallel array and in transverse edgewise alignment and being of sufficient inherent resiliency to normally tend to open up with included cards, means being provided for holding the cards relatively together at their bottoms, whereby the cards are separated at their tops by said strip members under the resilient urging of said pleats sufficient to maintain the cards in one area selectively fanned without skewing thereof for ease of viewing relative to cards in another area of the tray.
