DETAILED DESCRIPTION OF THE INVENTION

The present inventor recognized that hanging file systems provide advantage for storing and cataloguing small planar objects, such as optical memory storage disks, including CDs and DVDs, magnetic memory storage disks, including floppy disks, and paper or plastic products including photographs, checks, receipts, credit cards, photographs, greeting cards, personal notes, deposit slips, memos, recipes, ticket stubs, and cards, such as baseball cards, time cards, and golf score cards. He recognized that hanging file systems permit storing CDs or other small planar objects alphabetically, chronologically, or in any other desired organization. He also recognized that they have advantage in that they permit additional CDs to be added at any desired location in the file without having to move other files to maintain the organization. They also permit CDs to be removed from any location without having to move other files to maintain the organization. He also recognized that they also allow several CDs to be stored in each hanging file folder, each in its own protective envelope. They also allow printed documentation to be stored in each hanging file folder along with a CD. They also permit convenient labeling and provice an easy way to locate a particular CD.

The present inventor recognized that by shrinking dimensions for standard hanging file folders he could provide an improved system for storing and cataloguing CDs and other small planar objects at very low cost while provided a compact storage system whose dimensions fairly conform to the size of the small planar object.

The present inventor also recognized that two or more rows of such shrunken hanging file folders could be provided in a standard letter or legal sized filing drawer. He provided an adapter for a standard letter and legal sized filing drawer so that two or more rows of hanging file folders could be arranged in either of these drawers. He also provided a portable container sized to match the shrunken hanging file folders.

Standard letter size file drawer 10 includes two rows 12a, 12b of hanging file folders 13, as shown in FIGS. 1a, 1b. Each hanging file folder 13 is fabricated of folded heavy paper, and has open sides 14, as shown in FIG. 2a, similar to standard low cost letter and legal sized hanging file folders but smaller in at least one dimension. Hanging file folder 13 can have either a V shaped bottom 15a or it can have a flat bottom 15b (FIG. 5b) to accommodate a larger number of CDs or other small planar objects.

Each hanging file folder 13 has a hanger spacing L_H, as shown in FIGS. 1, 2a, 2b, and 3. L_H is the distance between midpoints 16a, 16b of hangers 18a, 18b. L_H is about 5⅝ inches to accommodate compact disks or video disks, as shown in FIG. 3. Hangers 18a, 18b hang from pair of rails 20a, 20b and from pair of rails 22a, 22b in file drawer 10. Rails 20a, 20b and rails 22a, 22b are spaced from each other by this same 5⅝ inch distance to accommodate these hanging file folders 13. Standard compact disks, which typically have a diameter of about 4¾ inches, are stored in envelope 24a, 24b that has an envelope length L_E of about 5 inches, as shown in FIGS. 4a 4b. In this case hanger spacing length L_H is preferably in the range from about 5⅜ inches to about 5¾ inches, and more preferably 5⅝ inches, so that two rows of hanging file folders 13 can fit in standard letter sized file drawer 10.

Preferably envelope 24a, 24b is provided for holding each individual CD, DVD, floppy disk, photographic film or prints, or other small planar object within folder 13, thereby allowing storage of multiple such small planar objects in each hanging file folder 13 while avoiding the possibility of one small planar object scratching another. Envelope 24a, 24b also permits handling without risk of placing fingerprints on the CD or other small planar object. Envelope 24a, 24b is sized to hold the CD, DVD, floppy disk or other small planar object. For a CD, envelope 24a, 24b is approximately square and with a dimension of about 5 inches on a side.

Envelope 24a, 24b may be fabricated of paper or it may be fabricated of a transparent material, such as plastic. It can also be fabricated of a non-woven fabric. Alternatively a paper envelope may have transparent plastic portion 26, allowing CD 27 or a label on CD 27 to be viewed without opening the envelope, as shown in FIG. 4a, which illustrates window type CD envelope 24a that is well known in the art. Envelope 24a may have flap 28, as shown in FIG. 4a or flap 28 may be omitted, as shown for envelope 24b in FIG. 4b which provides another prior art way to see CD 27 within.

In some cases an envelope may not be needed, for example, where only a single small planar object is stored in each folder 13 or for storing recipes or receipts for which there is no concern about scratching.

Printed insert piece 30 may be included in hanging file folder 13, along with CD 27 enclosed in envelope 24a, 24b to provide identifying information or other information about CD 27, as shown in FIGS. 5a, 5b.

Midpoints 16a, 16b of hangers 18a, 18b typically extend about ¼ inch beyond side edges 34a, 34b of folder 13, as shown in FIG. 3. Thus, bottom edge 36 of folder 13 has length L_F that is about ½ inch less than hanger spacing L_H. For dimensions given above, this means that bottom edge 36 has a length L_F that is about 5⅛ inches long, about ⅛ inch longer than envelope length L_E. Bottom edge 36 preferably has a length that is about equal to or greater than length L_E of envelope 24.

Hangers 18a, 18b each extend to hanger ends 38a, 38b about ¼ inch beyond their midpoints 16a, 16b, making the total spacing from rail 20 to end 38b of hanger 18b about equal to 5⅞ inches. Two such rows 12a, 12b thus take up about 11¾ inches of the space between rails of standard file drawer 10. Spacing between rails of a standard letter sized file drawer is about 12⅛ inches. Thus, there is about ⅜ inch clearance between ends 38b of hangers 18b of hanging file folders in row 12a and ends 38a of hangers 18a of hanging file folders in row 12b in the two row system shown in FIGS. 1a, 1b. Greater clearance is available by providing the double row adapters in a legal size drawer or by shrinking some of the dimensions.

Of course, all of these dimensions can be changed. For smaller sized CDs or for smaller planar objects, hanging file folders 13 can be fabricated with hanger length L_H that is smaller than the approximately 5⅝ inches described herein above. For small planar objects having a sufficiently small length so that L_H is reduced below about 3¾ inches, 3 or more rows of hangers can be provided in a standard letter or legal size file drawer. Alternatively these smaller hanging file folders can be stored in specially fabricated box 60, as shown in FIGS. 6a–6c, that is sized to match the dimensions of folders 13.

For planar objects having a diameter or length larger than that of standard CDs but smaller than spacing available in letter sized hanging file drawer 10, hanging file folders with correspondingly larger L_H can be fabricated. In this case only one row of hanging file folders 13 may fit across standard letter size file drawer 10. Hanging file folders with an L_H sized to match the diameter or length of the small planar object can be used with an adapter in standard letter or legal sized drawer 10, as described herein above. Alternatively, these hanging file folders can be stored in specially fabricated box 60 that is sized to match the dimensions of folders 13, as shown in FIGS. 6a–6c.

With envelope 24a, 24b having a vertical dimension V_E of about 4⅞ inches, hanging file folder 13 would preferably have vertical dimension V_F that is about ⅜ inch more or about 5¼ inches. This dimension can range from the diameter of a CD of about 4⅝ to about 9 inches.

For accommodating other small planar objects, other length and vertical dimension for file folder 13 can be chosen that are slightly larger than the dimensions of the object being stored. Such hanging file folders can be sized to accommodate other small planar objects such as floppy disks, checks, receipts, credit cards, photographs, greeting cards, personal notes, deposit slips, memos, recipes, ticket stubs, and cards, such as baseball cards, time cards, and golf score cards. For envelopes holding 5×7 photographs for example, this vertical dimension of hanging file folder 13 might be around 7½ inches. For floppy disks having a vertical dimension of 3⅝ inches, vertical dimension of hanging file folder 13 would be about 4 inches. Thus, L_H can be as small as about 1½ inches, and L_H can range up in size corresponding to the length dimension of the small planar objects being stored. Similarly, length L_F can be as small as about 1 inch and L_F can also range up in size corresponding to the vertical dimension of the small planar objects. In the present invention, hanging file folders having length and vertical dimensions are provided to match the dimension of a product that is produced in sufficiently high volumes.

Rails 20a and 22b in FIGS. 1a, 1b may be the standard rails that are integral with standard letter sized drawer 10. Alternatively, rails 20a and 22b may be standard rails that are part of a standard adapter that is routinely used to fit into those letter or legal sized file drawers that do not have integral rails. Rails 20b and 22a are additional rails provided to accomplish the present invention within a standard letter or legal sized file drawer. In one embodiment, rails 20b and 22a may be supported by end rails (not shown) that may be integral with some standard letter sized file drawers.

Alternatively, rails 20b and 22a may be supported by end portions of a standard adapter used for letter or legal sized file drawers 10 (not shown) using clamps, as shown in FIG. 1a.

For drawers having integral rails 20a, 22a (but not having integral end rails), two end support hangers 40a, 40b, may be provided, as shown in FIGS. 1b, 7a, and 7b, to form adapter 41a for letter sized drawers. A similar adapter 41b for legal size drawers is shown in FIG. 7c. Each end support hanger 40a, 40b extends from integral rail 20a to integral rail 22b. Additional rails 20b and 22a are supported by these added end support hangers 40a, 40b, as shown in FIG. 1a and FIGS. 7b, 7c. In one embodiment additional rails 20b and 22a extend through holes 42 in end support hangers 40a, 40b and are secured in end piece 44. Alternatively, rails 20b and 22a can be welded to end support hanger 40a, 40b.

Adapters 41a, 41b have a width W_A to fill a portion of drawer 10, as shown in FIG. 1b, and FIGS. 7a, 7c, leaving room for letter sized folders to be stored in the same drawer if desired. Alternatively, width W_A can be extended to fully fill drawer 10, as shown in FIG. 1a for adapter 41c formed with clamps.

Special end support hangers 40a, 40b are sized similar to hangers used to support standard letter sized hanging files that fit between rails 20a and 22b in a standard letter sized file drawer 10. However, special end support hangers 40a, 40b may be fabricated of a thicker material than used for hangers for letter or legal sized hanging folders since they will be bearing the weight of a large number of hanging file folders 13.

Hangers 18a, 18b may be formed with a single metal or plastic bar 46 extending through fold 48 in hanging file folders 13, as shown in FIG. 2b. Slots 50 can be provided in fold 48 to securely hold plastic tabs 52 that can hold identifying labels 54.

Adapter 41d for a letter sized drawer to provide for storing different sized small planar objects in each of two different length rows 43a, 43b is shown in FIG. 7d.

Substantial advantage is provided by shrinking dimensions of hanging file folders 13 from standard letter size to more nearly fit small planar objects. As described herein above, with CD hanging file folders 13 of the present invention being significantly smaller than ordinary prior art hanging file folders, standard file drawer 10 could hold two rows of such hanging file folders 13, using available space more efficiently and allowing finer cataloguing of CDs.

Specialized portable filing box 60 can be provided, as shown in FIGS. 6a–6c, sized for holding shrunken hanging file folders 13 of the present invention. Box 60 includes rail 62 and rail 64 spaced a distance L_H from each other to accommodate spacing L_H between midpoints 16a, 16b of hangers 18a, 18b of hanging file folder 13. Box 60 has a box length L_B sufficiently larger than length L_H of hanging file folders 13 to provide spacing for extending portions of hangers 18a, 18b of hanging file folders 13 and the thickness of side walls 66 of box 60. Box 60 has a vertical dimension V_B sufficiently larger than vertical dimension V_F of hanging file folders 13 to provide at least a small spacing under hanging file folders 13 and to take into account the thickness of the bottom surface (not shown) of box 60.

Portable filing box 60 preferably includes cover 68 having hinge 70 and latch 72 for retaining files in box 60 during transport. Cover 68 can include retaining bars 74 for holding hanging file folders 13 in place, as shown in FIGS. 6a, 6b. Retaining bars 74 may be fabricated of a pliable material, such as foam rubber to firmly hold hanging file folders 13 and their contents in place during transport. Preferably retaining bars 74 are located to avoid pressing on labels 54.

Alternatively, filing box 80 can be provided that needs no cover. File folders 13 and their contents can be secured in filing box 80 by providing elastic hold-downs 82, as shown in FIG. 6c. Elastic hold-downs 82 are secured to filing box 80 around button-shaped pins 84 that are connected to four edges of filing box 80, as shown in FIGS. 6c–6e.

Box 60, 80 may be fabricated of a material such as clear or opaque plastic, wood, metal, cardboard, or corrugated. Heavy paper, leather, or cloth could also be used with an internal frame. Preferably box 60 has rounded corners and handle 76 for easy carrying, as shown in FIG. 6a.

While several embodiments of the invention, together with modifications thereof, have been described in detail herein and illustrated in the accompanying drawings, it will be evident that various further modifications are possible without departing from the scope of the invention. For example, hanging file folders 13 can be fabricated of plastic or can have various colors. Nothing in the above specification is intended to limit the invention more narrowly than the appended claims. The examples given are intended only to be illustrative rather than exclusive.
