Abstract

Abstract A file entirely of cloth construction for the orderly, nondamaging storage of documents within a safe deposit box. A flexible cloth cover and attached divider sheets receive the papers to be stored whereupon the file is folded lengthwise to a width acceptable for insertion into a safe deposit box. A back portion of the cover carries the divider sheets and is flexible, along with the remaining portion of the file, to facilitate safe deposit box entry and removal. The divider sheets, upon opening of the file, have offset edges with indices to promote rapid locating of the document sought. The divider sheets are arranged in sets and are attached to the back portion of the file cover by spaced rows of stitching.

Claim 1
Independent Claim 353 words
A file for documents ordinarily kept within a safe deposit box the file being both foldable and flexible along with its contents without creasing of its contents to facilitate insertion of the file into said box or other smaller storage area, said file comprising: a unitary rectangular cover of woven pliable material including a front portion, a rear portion and a central back portion, with each of said portions having a rectangular cross-section and being foldable along their respective contiguous edges, said back element includes a medial fold line parallel to the ends of said cover, thereby forming a flexible back portion which is folded against the front and rear portions, respectively, a first set of stacked rectangular divider sheets of woven material and slightly less in size than said cover overlying same when the file cover is open, said divider sheets having central fold lines parallel to the ends of said sheets and in substantial registry with said cover, parallel spaced apart rows of stitching through said cover and said divider sheets along their common fold lines, additional sets of stacked rectangular divider sheets of woven material, said additiona sets comprising a quantity of centrally folded sheets stacked at parallel intervals along their central fold lines to that portion of the first set of divider sheets overlying the inwardly folded back portion of each sheet of the additional sets and being of less size then the first set of divider sheets, said sets being of a woven fabric characterized by a stiff finish for desired frictional resistance to displacement of an inserted document, indices carried by each of said sheets with the indices of said first set of sheets being laterally offset from remaining indices on said additional sets of sheets when the file is open, and said cover and sets of divider sheets when closed with documents therein adapted to be folded in a lengthwise direction parallel to the end of the cover without creasing of the documents and additionally flexible in a transverse direction when so folded to facilitate both insertion and removal from a storage area of restricted size.
