Abstract
Abstract A tabular indexing system is provided having index insert sheets incorporating perforations defining a plurality of index tabs, so that unused index tabs may be removed from the insert sheets, and protective carries into which the index sheets are inserted. The index insert sheets are preferably the size of a full sheet of paper and may be used in photocopiers for making multiple sets of indexes. Index insert sheets having pre-formed, die-cut tabs also may be used. The protective carriers are suitable for use in loose-leaf binders or the like. The index insert sheets may be provided with perforations defining semicircular tabs that may be opened and used for holding additional sheets of paper on the insert to prevent the index tab from being covered.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
90 words
In a tabular indexing system having divider sheets placed between pages to be indexed, an indexing system having: index insert sheets having index tabs along at least one edge; and protective carriers having an enclosed pocket area for carrying said index insert sheets, said protective carriers being closed along at least two edges, thereby defining the enclosed pocket area, open along at least a first edge for allowing insertion of the index insert sheets such that the tabs of the index insert sheets extend beyond the pages to be indexed.
Claim 2
Dependent Claim
90 words
In a tabular indexing system having divider sheets placed between pages to be indexed, an indexing system having: index insert sheets having index tabs along at least one edge; and protective carriers having an enclosed pocket area for carrying said index insert sheets, said protective carriers being closed along at least two edges, thereby defining the enclosed pocket area, open along at least a first edge for allowing insertion of the index insert sheets such that the tabs of the index insert sheets extend beyond the pages to be indexed.
Claim 3
Dependent Claim
25 words
The tabular indexing system of claim 1 wherein the index insert sheets have perforations along at least one edge defining a plurality of index tabs.
Claim 4
Dependent Claim
65 words
The tabular indexing system of claim 1 wherein the index insert sheets have semicircular perforations defining holding tabs, located adjacent the index tabs, that may be bent away from the index insert sheet on either side, thereby preventing a sheet of paper placed on either side of the index insert sheet under the bent holder tab from shifting so as to cover an index tab.
Claim 5
Dependent Claim
58 words
The tabular indexing system of claim 1 wherein the index insert sheets have projecting portions forming index tabs and the protective carriers are provided with projecting portions along an edge, the enclosed pocket area of the protective carrier including the projecting portion, such that the said projecting portions accomodate the projecting index tabs of the index insert sheets.
Claim 6
Dependent Claim
15 words
The tabular indexing system of claim 1 wherein the protective carriers are constructed of polypropylene.
Claim 7
Dependent Claim
25 words
The tabular indexing system of claim 1 wherein the protective carrier is open along two adjacent edges for allowing insertion of the index insert sheets.
Claim 8
Dependent Claim
28 words
The tabular indexing system of claim 1 wherein the protective carriers have a plurality of holes along one edge for receiving the rings of a multiple ring binder.
Claim 9
Dependent Claim
118 words
In a tabular indexing system having divider sheets placed between pages to be indexed, the indexing system with divider sheets comprising: index insert sheets having index tabs along at least one edge, the index insert sheets being of the same size as the pages to be indexed; and protective carriers having an enclosed pocket area for receiving the index insert sheets, said protective carriers being closed along the periphery of at least two edges thereby defining the enclosed pocket area, and open along at least a first edge for allowing insertion of the index insert sheets such that the index tabs along at least one edge of the index insert sheets extend beyond the pages to be indexed.
Claim 10
Dependent Claim
118 words
In a tabular indexing system having divider sheets placed between pages to be indexed, the indexing system with divider sheets comprising: index insert sheets having index tabs along at least one edge, the index insert sheets being of the same size as the pages to be indexed; and protective carriers having an enclosed pocket area for receiving the index insert sheets, said protective carriers being closed along the periphery of at least two edges thereby defining the enclosed pocket area, and open along at least a first edge for allowing insertion of the index insert sheets such that the index tabs along at least one edge of the index insert sheets extend beyond the pages to be indexed.
Claim 11
Dependent Claim
40 words
The indexing system of claim 8 wherein the protective carriers are formed from a single sheet of polypropylene folded over on itself and having a plurality of holes along one edge for receiving the rings of a multiple ring binder.
Claim 12
Dependent Claim
34 words
The indexing system of claim 8 wherein the protective carriers are formed of two sheets of plastic and having a plurality of holes along one edge for receiving the rings of a multiple binder.
