Abstract
Abstract A binder made of a rigid covering case and containing an assemblage of envelopes constitutes a diskette file. The diskette file provides a secure receptacle suitable for storage of 10, 20, or any number of magnetic diskettes used on microcomputers. When the binder is open, an accordion-like assemblage of envelopes structure expands to form a fan of the diskettes stored in the envelopes. The top of each diskette in the fan of the open binder is revealed and a single diskette can be located and retrieved without having to manipulate any of the other diskettes in the file. The assemblage of envelopes is bound to the covering case. The case consists of 5 coupled and hinged sections; front, bottom, back, top and flap. The flap folds over and attaches to the front panel. When such a binder is closed, the book-like diskette file may contain a large number of diskettes in a well-protected, organized filing pattern suitable for cataloguing and storage in library book-shelf fashion.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
149 words
A binder for storing computer magnetic diskettes comprising a plurality of envelope sections attached to one another in an accordian-type manner and encased within a cover wherein: each envelope section is configured and dimensioned to substantially accommodate a single computer diskette therein and comprises a front panel and a rear panel joined together along their respective side and bottom edges with said rear panel having a height greater than said front panel, said side edges having an inwardly facing generally U-shaped edge; said envelope sections being successively joined together with a bonding material with the rear panel of each envelope section completely adhered to the front panel of the adjacent panel except for the side edges thereof and the bottom of said front and rear cover panels spaced a fixed predetermined distance so as to permit said envelopes and binder to open in a controlled accordian, fan-shape like manner.
Claim 2
Dependent Claim
149 words
A binder for storing computer magnetic diskettes comprising a plurality of envelope sections attached to one another in an accordian-type manner and encased within a cover wherein: each envelope section is configured and dimensioned to substantially accommodate a single computer diskette therein and comprises a front panel and a rear panel joined together along their respective side and bottom edges with said rear panel having a height greater than said front panel, said side edges having an inwardly facing generally U-shaped edge; said envelope sections being successively joined together with a bonding material with the rear panel of each envelope section completely adhered to the front panel of the adjacent panel except for the side edges thereof and the bottom of said front and rear cover panels spaced a fixed predetermined distance so as to permit said envelopes and binder to open in a controlled accordian, fan-shape like manner.
Claim 3
Dependent Claim
31 words
A binder as defined in claim 1, wherein the bonding material is applied to a panel of each envelope in such a manner that the assembled envelopes have pleated side edges.
Claim 4
Dependent Claim
37 words
A binder as defined in claim 1, wherein said bonding material is applied to an envelope panel in a general trapezoidal configuration leaving a triangular area at the edges of each panel free of said bonding material.
Claim 5
Dependent Claim
24 words
A binder as defined in claim 3, wherein the base of each said triangular area is at the top edge of said envelope panel.
Claim 6
Dependent Claim
37 words
A binder as defined in claim 1, wherein the cover comprises a plurality of hingedly connected sections encasing the assembled envelope sections, the front and rear envelopes of said assembly being adhered to the adjacent cover sections.
Claim 7
Dependent Claim
39 words
A binder as defined in claim 5, wherein the cover section underlying the assembled envelope sections confines the movement of the lower panel edges of each assembled envelope sections when said assembly is opened in a controlled accordian manner.
Claim 8
Dependent Claim
19 words
A binder as defined in claim 5 wherein each cover section is wider than each of the envelope sections.
Claim 9
Dependent Claim
35 words
A binder as defined in claim 5, wherein the last cover section overlies said first cover section and wherein said binder additionally includes means to fasten said last cover section to said first cover section.
Claim 10
Dependent Claim
150 words
A binder for storing computer magnetic diskettes comprising a plurality of envelope sections attached to one another in an accordian-type manner and encased within a cover wherein: each envelope section is configured and dimensioned to substantially accommodate a single computer diskette therein and comprises a front panel and a rear panel joined together along their respective side and bottom edges with said rear panel having a height greater than said front panel, said envelope sections being successively joined together with the rear panel of each envelope section completely adhered to the front panel of the adjacent panel with a bonding material applied in a trapezoidal configuration leaving a triangular area of the edges of each panel free of said bonding material with the bottom edge of each panel bonded along their entire length so as to permit said envelopes and binder to open in a controlled, accordian, fan-shape like manner.
Claim 11
