Definitions

• the present invention relates generally to index sheets and, more particularly, to bindable index sheets which can be directly printable on by machines, such as computer-operated printers.
• Index tabs for quick identification and selection of information from looseleaf or hardbound binders are a common feature of nearly every well-organized office or home.
• these index tabs are provided as markings on certain sheets or pages of binders, books, notebooks, or other multiple sheet material.
• the index tabs are typically staggered or spaced, along two orthogonal planes. For example, the index tabs connected to the edge of adjacent index sheets are positioned just far enough away from each other so that the identifying text or characters or symbols appearing on both index tabs can be seen simultaneously. Uses for such index tabs range from simple referencing to presentations .
• index tabs are made in one of two ways.
• the tabs may be integrally formed as protrusions of the sheets themselves as shown, for example, in U.S. Patent No.
• the tabs may be separate components which are connected to the index sheets as shown, for example in U.S. Patent No. 4,962,603 issued to Kao et al. on October 16, 1990; U.S. Patent No. 5,135,261 issued to Cusack et al. on August 4, 1992; U.S. Patent No. 5,340,427 issued to Cusack et al. on August 23, 1994; and U.S. Patent No. 5,389,414 issued to Popat on February 14, 1995.
• index tabs as integral protrusions of the index sheet has been disadvantageous, since it has been difficult to machine print identifying text on the index tabs. For example, it has b een impractical to insert the entire index sheet into a standard typewriter in order to type text sideways onto the protruding index tab. It has also been difficult or impossible to feed index sheets directly through common office printers, such as laser printers, inkjet printers or office copiers, without encountering jamming problems, limited feed size problems, or distorted printing problems.

• DETAILED DESCRIPTION OF THE INVENTION Referring to Figs. 1-14, wherein similar reference characters designate similar elements or features throughout the Figs., there is shown multiple embodiments of a generally-planar index sheet or divider 10,10' of the present invention. Referring to the embodiments shown in Figs. 1-8, the index sheet 10 comprises a generally rectangular main body 12, a bindable member 14, at least one index tab 16, and a guide 18.
• the main body 12 includes opposed spaced-apart first (lefthand binding) and second (righthand index) edges 20,22 and opposed spaced-apart third (top) and fourth (bottom) edges 24,26. Each of the third and fourth edges 24,26 intersect and are generally perpendicular to each of the first and second edges 20,22.
• the main body 12 of the index sheet 10 may be formed, for example, of a substantially-pure paper-based medium or a composite material such as a paper/plastic laminate.
• a paper/plastic laminate is a product known as DuralonTM which is made by Arlon, Adhesives and Film Division, Santa Ana, CA.
• DuralonTM has a tear-resistant plastic film bonded between two layers of premier stock. It can be used with laser and dot matrix printers, as well as office copiers.
• the bindable member 14 extends outwardly from the first edge 20 of the main body 12 and defines at least one bindable hole 28, spaced from the main body 12, and a relatively-thin section 30.
• This section 30 will, as described below, function to define a fold line.
• the relatively-thin section 30 is positioned between the bindable hole 28 and the first edge 20 and extends between the third and fourth edges 24,26 of the main body of the index sheet. As shown in Fig. 5 and Fig. 7, part of the bindable member 14 is connected to either planar side 32,34 of the main body 12 of the index sheet 10.
• the free end of the bindable member 14 has a relatively-thicker thickness, compared to the part connected to the main body 12, which provides additional strength against tearing and allows the bindable member 14 to be easily folded so that it lays flat against the main body 12.
• the bindable member 14 can be applied to the main body stock as each is fed from a separate roll. This assembly can then be punched and die cut to a desired size.
• the bindable member 14 includes a laminated subassembly connected to the main body 12. As shown in Fig.
• the bindable member 14 includes a base strip 36, having an inner portion 38 and an outer portion 40, an outboard cover strip 42, and an optional inboard cover strip 44-
• Each of the strips 36,42,44 may be formed substantially from a reinforced material such as mylar, a paper-based medium, DuralonTM, or the like.
• the outboard cover strip 42 is overlappingly directly connected or laminated to an opposite planar side of the outer portion 40 of the base strip 36, by an adhesive or the like.

• the base strip 36 has a first width W j of about 1.188 inches (about 30 millimeters)
• the outboard cover strip 42 has a second width w 2 of about 0.625 inches (about 16 millimeters)
• the inboard cover strip 44 may have a third width w 3 of about 0.500 inches (about 13 millimeters) .
• the relatively-thin section 30 of the bindable member 14 is defined by that part of the base strip 36 along the lateral spacing between the inboard cover strip 44 and the outboard cover strip 42.
• the relatively-thin section has a width w tone of about 0.0625 inches (about 1.6 millimeters).
• the base strip 36 has a first uniform thickness t. ⁇ and the outboard cover strip 42 has a second uniform thickness t 2 greater in magnitude than the first thickness tj .
• the inboard cover strip 44 has a third uniform thickness t 3 greater in magnitude than the first thickness t. of the base strip 36 and less in magnitude than the second thickness t 2 of the outboard cover strip 42.
• the base strip 36 has a first thickness t x of about 0.00057 inches (about 0.014 millimeters)
• the outboard cover strip 42 has a second thickness t 2 of about 0.0038 inches (about 0.097 millimeters)
• the inboard cover strip 44 has a third thickness t 3 of about 0.0015 inches (about 0.038 millimeters).
• the outboard cover strip 42 and the inboard cover strip 44, or even all three strips 36,42,44 may have about the same uniform thickness.
• the bindable member 14 may be a monolithic component having the varying thicknesses t.,t 2 ,t, and situated as described above. In still another alternative embodiment, the bindable member 14 may be integrally formed with the main body 12 of the index sheet
• the relatively-thin section 30 is operable to be folded and unfolded along a fold line 50.
• the bindable member 14 When the bindable member 14 is in its folded state shown in Fig. 6, the bindable member 14 extends generally across opposite sides of the first edge 20.
• the first edge 20 When the bindable member 14 is in its folded state shown in Fig. 6, the bindable member 14 extends generally across opposite sides of the first edge 20.
• the relatively- thin section 30 is operable to be folded and unfolded generally along only one side of the first edge 20.
• the outboard cover strip 42 is interposed between the inner portion 38 and the outer portion 40 of the folded base strip 36.
• the width of the thin section 30 may vary depending on which embodiment of Figs. 6 and 7 is employed.
• the relatively-thicker outboard cover strip 42 laminated to the base strip 36 is advantageous for controlling the folding of the relatively-thin section 30.
• the relatively- thicker outboard cover strip 42 laminated to the base strip 36 is also advantageous for easily forming, by punching or the like, the one or more bindable holes 28.
• the relatively- thin section 30 of the bindable member 14 enables the fold line 50 to be uniform between the third and forth edges 24,26 of the main body 12.
• the relatively-thin section 30 also allows the bindable member 14 to fold over and lie flat against the main body 12 (Fig. 6) or on itself (Fig. 8) without the need for an adhesive or the like to maintain it in that folded state.
• the inboard cover strip 44 helps to better define the location and edge at which the relatively- thin section 30 naturally folds.
• the construction of the thin section 30 between the inner and outer portions 38,40 with their cover strips facilitates the flat positioning of the bindable member when in its folded position. No separate attaching means is required to hold the bindable member in its folded position. This, therefore, facilitates easy arrangement of the index sheet into a folded position which will feed properly through the printing equipment.
