Description

HANGING FILE SYSTEM
BACKGROUND OF THE INVENTION
1. Field of the Invention This invention relates to paper filing systems, and more particularly to hanging file systems.

2. Description of Related Art In the past, hanging folders were designed to help maintain papers neatly in file drawers.
A hanging folder has hangers that extend from each end of the opening of the folder, which ride on rails provided across a file drawer. When papers are placed in the hanging folder, they are either first organized in a separate file folder or simply left loose in a stack. Chinese Utility Model Patent No. 982124627 (filed April 2, 1998; issued May 24, 1999; assigned to Idea Enhancement Group Inc., the assignee of the present application), disclosed a new hanging binder that organizes, binds and files the papers in a hanging file drawer, without requiring the use of a separate hanging folder and file folder. (This Chinese patent is fully incorporated by reference herein) The hanging binder disclosed has four posts spaced apart along a binding spine and a binder flap having four holes spaced apart to match the posts. The papers to be filed have holes punched along an edge at spacing matching the location of the posts. To file a paper, the paper is placed against the binder with the posts through the holes, and the binder flap is closed onto the posts with the tip of the posts into the holes on the binder cover.
The tips of the posts are snapped into the holes on the binder flap, thus securing the paper on the posts. To remove a paper, the binder flap is unsnapped to provide access to the paper. The hanging binder has a hanger extending from each end of its spine, which hangers may retract into the spine when the hanging binder is not placed in a hanging file drawer. Each hanger is separately supported in a cantilevered fashion by the two posts closest to the respective end.
The above-mentioned hanging binder maintains a stack of loose-leaf papers in an organized fashion for the convenience of future references. It also maintains the stack of loose-leaf papers in a manner that allows a person the flexibility and ease of inserting papers to or removing papers from the stack. Further, it maintains the stack of loose-leaf papers in a manner that allows easy turning of the pages to allow a person to review the papers.
The present invention provides an improvement over the earlier hanging binder design.

DESCRIPTION OF PREFERRED EMBODIMENTS
The present description is of the best presently contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
Reference is made to Chinese Utility Model Patent No. 982124627 (filed April 2, 1998;
issued May 24, 1999; assigned to Idea Enhancement Group Inc., the assignee of the present application), which is fully incorporated by reference herein.
The present invention is directed to a hanging file system that makes use of an improved hanging binder. The filing system includes a number of complementary hanging file supports, implementations and accessories.
In one aspect of the present invention, an improved hanging binder reduces the number of posts required to support retractable hangers. Figs. 1 to S illustrate the improved hanging binder in accordance with one embodiment of the present invention. The hanging binder 10 comprises an elongated spine 12 and two hanger members 20 and 22 slidable within the spine 12. The spine 12 has a generally U-shaped cross-section (i.e., generally a U-shaped channel; see Fig.
3A). It has a back 13 and two opposing flaps 14 and 15. The flap 15 has three posts 16 extending perpendicularly from the flap 15, across the inside of the spine 12, to the flap 14. The flap 14 is hingedly connected to the back 13 and has three holes 18 matching the location of the tips 19 of the posts. Referring also to Figs. 6 and 7, the holes 18 have a constriction 21, and the posts 16 have a ball-head tip 19 and a neck 17. The ball-head tip 19, neck 17, hole 18 and constriction 21 are sized to cooperate as a snap fastener, such that the posts 16 and the holes 18 snap together when the posts 16 are inserted through the holes 18. The posts 16 and holes 18 may have a cylindrical, oval, square or rectangular cross-sections. The illustrated embodiment shows an elongated oval cross-section. Alternatively, other types of releasable interlocking structure may be used for coupling the flap 14 and posts 16.
The spine 12 may be made of a plastic or light metal material. For example, plastic such as polyethylene and polyvinyl chloride may be used to make the spine. The flaps 14 and 15 and the back 13 may be formed from an initially flat piece of material. The flaps 14 and 15 may be bent from the back 13 and~shaped to form the U-shaped (cross-section) spine 12. To facilitate bending, the sheet material may be scored at the bends 1 and 2 (Fig. 3A) or the thickness of the material is otherwise reduced at the bends. The bend 2 acts as a hinge for the flap 14. The posts 16 may be formed integral to the flap 15 or separately and welded to the flap 15. Alternatively, the flaps 14 and 15 may b separate pieces connected to the back 13.
Referring to Figs. 3B to 5, the hanger members 20 and 22 have a generally L-shaped cross-section, except at the ends 24 and 25. The ends 24 and 25 are generally U-shaped in cross-section, and have generally U-shaped notches 26 on the sides, which define hangers 27 for riding on hanging file support rails typically provided in file drawers and the like.
The hanger members may be made out of the same materials that can be used to make the spine. At the other ends 28 and 29 of the hanger members 20 and 22, the hanger members can slide relative to one another in a telescopic manner. The end 28 is reduced in overall size to fit inside of the end 29. Figs. 2, 3, and 4B show the hanger members in an extended state;,Figs 1 and 4C show the hanger members in a fully retracted state.
On each hanger member, there are two elongated slots (30, 31, 32, 33). The slots 30-33 are positioned such that the posts 16 extend through the slots 30-33 in the assembled binder. In the assembled state, the slots 31 and 32 overlap at the center post 16. The slots 30-33 are so sized and positioned such that in the fully extended position of the hanger members 20 and 22, the posts 16 stops at the inside ends 34-37 of the slots 30-33; and in the fully retracted position, the posts 16 stops at the outside ends 38-41 of the slots 30-33. The slots 30 and 33 have generally V-shaped or half-round protrusions 44 along the longitudinal edges of the slots 30 and 33. The protrusions 44 are positioned from the ends 34, 37, 38 and 41 of the slots 30 and 33 such that the posts 16 are trapped by the protrusions 44 when the posts are against the ends 34, 37, 38 and 41 of the slots 30 and 33. When the hanger members are in the fully retracted state as shown in Fig. 4B, the posts 16 are trapped against ends 38 and 41 of slots 30 and 33. In the fully extended state as shown in Fig. 4C, the posts 16 are trapped against ends 34 and 37 of slots 30 and 33. The posts 16 can slide over the protrusions 44 upon applying a force to extend or retract the hanger members 30 and 33. To facilitate sliding over the protrusions 44, slots 46 are provided in parallel to the edge of the slots 30 and 33 on which the protrusions 44 are located, next to narrow adjoining strips 48. When a force is applied to slide the hanger members 30 and 33 relative to each other, the posts 16 press against the protrusions 44, and in a cam action, push the protrusion "aside" while the narrow adjoining strips 48 flex to give way laterally because of the slots 46.
The hanger members 30 and 33 are essentially supported in a cantilevered manner by the posts 16. Two posts 16 are needed to support each hanger member. By using a common center post 16 to support the inside end of each hanger member, the number of posts is reduced, thus simplifying the design and construction of the hanging binder 10.
The size of the hanging binder 10 may correspond to any standard size paper, such as A4 size, legal size, letter size, etc. The position and spacing of the posts 16 may correspond to the spacing of holes made by standard hole-punchers.

To file a paper in the hanging binder 10, the flap 13 is opened at its hinge at bend 2, away from the posts 16. The paper is placed against the back 13 with the posts 16 through holes punched along one edge of the paper. The flap 14 is closed onto the posts 16 with the tip 19 of the posts into the holes on the binder cover. The tips 19 of the posts 16 are snapped into the holes 18 on the flap 14, thus securing the paper on the posts 16. To remove a paper, the flap 14 is unsnapped from the posts 16 to provide access to the paper. Fig. 1 shows the hanging binder with papers 4 filed thereon. The hanger members may be retracted into the spine 12 to conceal the hanger 27 when the hanging binder 10 is not placed in a hanging file drawer. This provides a clean elegant binder that can be handled without the hangers 27 getting in the way. When the binder 10 is placed in a file drawer, the hanger members 20 and 22 are extended to expose the hangers 27. The binder is supported with the hangers 27 riding on rails typically provided in a file drawer, in which the papers filed thereon will hang vertically.
Unlike the four-pin structure, which requires snapping and unsnapping of four posts to place and remove papers from the binder, less posts used in the present invention results in a structure that requires less effort for a person to use the binder 10.
In another aspect of the present invention, hanging binder supports are designed to complement usage of the hanging binder to provide filing of loose-leaf papers.
As shown in Fig.
8, in accordance with one embodiment of the present invention, a hanging file sleeve or box 50 provides support for portable storage of hanging file. The box 50 has a rectangular sleeve 52 having an opening 54. Inside the opening, at two opposing ends are support rails 56. In the embodiment shown, the opening is a narrow rectangular shape, and the support rails are slots oriented with their edges facing towards the opening. The size of the sleeve 52 and the spacing between the rails 56 are such to match the hanger 27 when they are fully extended from the spine 12. The hanging binder 10 can be inserted in the sleeve 52 and supported on the rails at the hangers 27. The distance between the rails 56 and the edge of the opening 54 may be such that the back 13 of the binder 10 would be flush with the edge of the opening 54 when the binder 10 is supported on the rails 56. This results in an elegant profile. To facilitate removal of binders 10 from the sleeve 52, the panels at the sides of the opening 54 are provided with cutouts 58.
It is noted that while the box 50 is designed for supporting hanging binders horizontally (i.e., the opening 54 horizontal), the box 50 may be stored on a shelf with the opening 54 vertical. It is expected that one would typically insert and remove binders 10 with the opening horizontal. The width of the sleeve 52 may be any size desired to hold a desired number of hanging binder 10. The hanging binders 10 may be color coded in accordance with subject matter.
Referring to Fig. 9, in accordance with another embodiment of the present invention, a hanging tile carrying case 60 provides easy transport and handling of hanging files. The case 60 is essentially similar in structure as the box 50 in the previous embodiment, with the exception that a carrying handle 62 is provided on an additional panel 64 that closes the opening 66. There is also a panel 68 that has a clasp, latch or other types of fastener 69 that secures the panel 68 in a closed position. There are rails 67 and cutouts 65 as in the previous embodiment. Optional flaps 63 may be provided at opposing ends of the opening 66. This may be folded and tucked under the panel 64 to protect the hanging binders 10 carried in the case 60.
The case 60 and the sleeve 52 may be made of a rigid material, such as plastic or metal.
Referring to Fig. 10, in accordance with a further embodiment of the present invention, a foldable hanging file base 70 facilitates storage of the case during shipping and saves space when not in use. The base 70 comprises a frame structure of slender members 72. The members 72 may be made from solid rods or hollow tubes of light metal or plastic. Two horizontal members 74 provide the support rails for hanging binders 10 shown in dotted lines in Fig. 10. Soft or flexible panels 71 may be supported or draped between the members 72 to form an enclosure to provide protection of the contents from the environment. The frame structure may be folded or collapsed at hinge 76 to a generally flat profile when the case 60 is not in use.
In another aspect of the present invention, a hanging binder supports a receptacle that provides filing of loose papers and/or articles. Referring to Fig. 11, in accordance with one embodiment of the present invention, the receptacle is in the form of an envelope or a file pocket 80, which has holes 82 punched along flange 83 for hanging on the posts 16 on the hanging binder 10. The file pocket 80 may have a flap 84 that closes an opening in the file pocket 80 for insertion of papers or articles by means of a Velcro fastener 88 or other types of releasable fastener or clasp. The file pocket 80 may be made of clear, colored and/or translucent plastic. A
Label holder 86 may be provided on the front of the file pocket 80 for holding a content identification label.
In another aspect of the present invention, a hanging binder supports at least one loose cover with enough stiffness to protect the contents within the hanging binder during handling and storage. Referring to Fig. 12, in accordance with one embodiment of the present invention, the cover structure 90 consists of a front cover 98 and a back cover 99, both of which have holes 92 punched along flanges 93 for hanging on the posts 16 on the hanging binder 10.
Since the holes 92 hang on the posts 16, the cover structure 90 can be removed from the binder 10 or reconfigured in any manner desired by the user. A label holder 96 may be provided on the front cover 98 for holding a content identification label. The front and back covers 98 and 99 are generally flat, preferably made of a plastic material. The material chosen should be stiff or the thickness of the material should be chosen so that the covers are of a stiffness that adequately protects the contents during handling and storage.
In another aspect of the present invention, a hanging binder has a fixed outer jacket that protects the contents within the hanging binder, as well as the hanging binder itself, during -_ handling and storage. Referring to Figs. 13 and 14, in accordance with one embodiment of the present invention, the jacket structure 100 comprises jacket front 102, jacket back 104, and jacket side 106 that surround flap 14, flap 15, and back 13> respectively, of the spine 12. The jacket front 102, back 104, and side 106 may be integrally formed from a single piece of material by bending along corners 112 and 114. Alternatively, the jacket structure 100 may be separately formed and then joined. The jacket structure 100 is attached to the spine 12 and extends to cover the contents within the hanging binder 10. In the illustrated embodiment, rivets 110 attach the jacket structure 100 to the spine 12. The jacket structure 100 may be attached to the spine 12 by other means, such as by using other fasteners besides rivets, by applying an adhesive, by plastic welding, or even by forming the jacket structure and the spine as an integral structure. In accordance with another embodiment of the present invention, the jacket structure 100 has one or more clear pockets 120 on the jacket front 102, jacket back 104, or jacket side 106 so that the pocket 120 can display papers, which slide in an opening 122. The pocket 120 is attached to the jacket structure 100 by any adhesive, joining, or forming means.
While the invention has been described in detail with respect to the illustrated embodiments in accordance therewith, it will be apparent to those skilled in the art that various changes, modifications, substitutions, alterations and improvement may be made without departing from the scope and spirit of the invention as defined by the appended claims.
