Abstract
Abstract The present invention is an improved information organizing device fashioned from a sheet material in which columns of parallel slits are made. These slits form columns of opposing, downwardly converging legs of material. Between these legs of material is placed a pinch crease that imparts a twist in the legs raising certain edges of the legs and thus facilitating the insertion of information vehicles such as memo cards.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
113 words
An information organizing device comprising: (a) at least one sheet of a flexible material restrained at its edges from inward movement; (b) at least two, side by side, spaced columns of downwardly converging slits, each column having a plurality of nearly parallel slits made in said sheet of said flexible material to form legs in said material between parallel slits; and (c) a pinch crease fashioned into said sheet of said flexible material along a central axis between the columns of slits and spaced from the near terminal ends of the parallel slits, the pinch crease gathering the sheet material toward the central axis so as to impart a twist into the legs.
Claim 2
Dependent Claim
113 words
An information organizing device comprising: (a) at least one sheet of a flexible material restrained at its edges from inward movement; (b) at least two, side by side, spaced columns of downwardly converging slits, each column having a plurality of nearly parallel slits made in said sheet of said flexible material to form legs in said material between parallel slits; and (c) a pinch crease fashioned into said sheet of said flexible material along a central axis between the columns of slits and spaced from the near terminal ends of the parallel slits, the pinch crease gathering the sheet material toward the central axis so as to impart a twist into the legs.
Claim 3
Dependent Claim
46 words
An information organizing device as recited in claim 1 further comprising: (d) a rigid inner sheet over and above which at least one sheet of said flexible material, restrained at its edges from inward movement by said rigid inner sheet, is placed to construct a panel.
Claim 4
Dependent Claim
25 words
An information organizing device as recited in claim 2 wherein at least one of said panels is constructed in the fashion of a notebook page.
