1. Field of Invention
The present invention is generally related to hanging file folders for mounting to a pair of spaced apart rails. More specifically, the present invention is related to hanging file folders with a structure for permitting adjustment of an effective length of its rod for accommodating variances when adjusting folders along spaced apart rails.
2. Background
Hanging file folders for holding papers and documents within a pocket in a filing cabinet with parallel, spaced apart rails are known in the art. However, some hanging file folders tend to have a limited amount of strength and may not provide ease for sliding the folders along the length of rail when holding documents.
For example, as the load within the pocket of a file folder increases, the hooks and rods for hanging the file folder require increased strength in order to provide suitable engagement with the rails of a filing cabinet or the like. The hooks and rods must also be designed to resist derailing of the file folder from the rails. For example, as the load increases, a file folder may be twisted or flexed and may lock onto the rail. Thus, file folders with increased strength and better engagement with the rails of a filing cabinet are beneficial.
Additionally, the spaced apart rails within cabinets may not be provided perfectly at the same distance. For example, rails within a filing cabinet may not be parallel or may not be spaced the same distance from one another in one drawer or cabinet as compared to another. Also, file folders generally hang perpendicular to the rails when at rest.
One aspect of the invention provides a hanging file folder for mounting to a pair of spaced apart rails. The hanging file folder includes a first rod with a pair of hook portions on opposing ends thereof for engaging the pair of spaced apart rails; a second rod with a pair of hook portions on opposing ends thereof for engaging the pair of spaced apart rails; and a file folder body with first and second walls forming a pocket for holding materials therein. The first wall of the file folder body is connected to the first rod, and the second wall of the file folder body is connected to the second rod, such that the pocket is suspended between the first and second rods. At least one of the first and second rods has a resilient structure for permitting at least one of the hook portions thereof to move longitudinally and adjust an effective length of its rod for accommodating variances in the angle at which folders are mounted on the rails and maintaining engagement therewith.
An aspect of the invention provides a method of forming a hanging file folder for mounting to a pair of spaced apart rails. The method includes forming a first rod with a pair of hook portions on opposing ends thereof; forming a second rod with a pair of hook portions on opposing ends thereof; attaching a first wall of a file folder body to the first rod; and attaching a second wall of the file folder body to the second rod. At least one of the rods includes a resilient structure for permitting at least one of the hook portions thereof to move longitudinally and adjust an effective length of its rod for accommodating variances in the angle at which the folders are mounted on the rails to maintain engagement therewith.
Another aspect of the invention includes a rod for mounting to a pair of spaced apart rails. The rod includes an elongated body for hanging an object therefrom. The body has a first end and a second end. A pair of hook portions are provided on opposing ends of the rod for engaging the pair of spaced apart rails, and a resilient structure is provided to permit at least one of the pair of hook portions to move longitudinally with respect to the elongated body. An effective length of the body is adjusted to accommodate variances in the angle at which the rod is mounted on the rails and to maintain engagement therewith.

Generally, file folders may be laterally or perpendicularly hung on spaced apart rails provided within a drawer of a filing cabinet. As known in the art, file folders may be mounted on spaced apart rails running generally parallel with the length of the drawer or on spaced apart rails that may run parallel to the width of the drawer. For the herein disclosed embodiments, any type of rail system may be used. For example, as shown in
As another example,
Nonetheless, the above rails as shown in
The first wall 12 of the body 11 is connected to a first rod 18 and the second wall 14 of the body 11 is connected to a second rod 20. A bottom end of first wall 12 is connected to a bottom end of the second wall 14 of the body 11 of the file folder 10 at 13, thus forming a pocket 16 therebetween. The pocket 16 of the folder 10 is designed such that it is suspended between the first and second rods 18, 20. The folder 10 may be connected to the rods 18, 20 in any number of ways. For example, in an embodiment, an open end 22 of the first wall 12 and an open end 24 of the second wall 14 may be designed such that they surround the first rod 18 and second rod 20, respectively (e.g., as shown in
The hook and rod assembly 30 comprises a hook portion 32 and a rod portion 62. In an embodiment, hook and rod assembly 30 may be formed as a single unit. In an embodiment, at least one of the first and second hook portions 32 of the assembly 30 may be removably attached to the first and second rods 18, 20 or rod portions 62.
a illustrates an example of the removably attached hook portion 32 of
In an embodiment, hook 39 comprises an elongated portion 40 and a longitudinal portion 42. Elongated portion 40 of hook 39 also comprises an end portion 46. In an embodiment, elongated portion 40 may comprise a bulbous end portion 46, as shown in
Longitudinal portion 42 extends into a hook body 44. The end of longitudinal portion 42 transitions into hook body 44 and includes an extension portion 50 and an abutment portion 54. Extension portion 50 is formed such that it comes into contact with an opposite (i.e., inner) side of a rail when hanging file folder 10. In an embodiment, as shown in
The hook body 44 may also comprise a limiting portion 52. In an embodiment, the limiting portion 52 is provided as a stop for limiting the amount of longitudinal movement of the hook portion 32 with respect to rod portion 62. The area 51 between the extension portion 50 and limiting portion 52 provides a bearing surface for the hook portion 32 to move or slide on a a part of the rod, as will be discussed in greater detail below. Thus, limiting portion 52 limits the length the bearing surface 51 may move with respect to the rod 62.
As previously noted, at least one of the first and second rods may have at least one hook portions thereof moveably mounted to the rod portion 62. In an embodiment, the resilient structure is constructed and arranged between the rod 62 and the hook 39 near the distal end 38 of hook portion 32. In an embodiment, the hook body 44 of hook portion 32 comprises a resilient structure 58 as shown in
In an embodiment, the resilient structure 58 may be formed integrally as one continuous piece with the hook portion 32. For example, in an embodiment, the hook portion 32 is formed through a stamping, punching, or molding process. In an embodiment, hook portion 32 may be formed of nylon. The hook portion 32 may be of any known length. The elongated portion 40 of the hook 39 of hook portion 32 may be designed to extend below the height of a rail, for example. In an embodiment, the length (e.g., length L of the elongated portion 40 from the top of longitudinal portion 42 to the end portion 46 along Y-axis, as indicated in
In an embodiment, hook portion 32 may comprise a depth or thickness T of 2 millimeters (mm) and a length L of 9.6 millimeters (mm). In an embodiment, the hook portion 32 may comprise a thickness T to minimize the impact of the drawer space used by the file folder 10. That is, the thickness T may be adjusted such that a drawer may hold more file folders based on the depth or thickness of the hook. For example, a drawer maybe designed to hold eighty (80) file folders. However, by adjusting the depth or thickness T of the hook in the Z-direction (i.e., along Z-axis, as indicated in
The distance of the bearing surface 51 is set to limit the extension of the resilient structure 58. For example, the distance of the bearing surface 51 may be determined by a distance needed to extend the file folder. In an embodiment, the distance of the bearing surface 51 may also be determined by the amount of flexure or “flex” that would cause the resilient structure 58 to permanently yield (i.e. experience plastic deformation). In an embodiment, the amount of flex may be determined or affected by the material used to form resilient structure 58. For example, a material such as nylon may bend more than a high density polyethylene (HDPE) before yielding. In an embodiment, resilient structure 58 may comprise the material of which the hook portion 32 comprises. In an embodiment, the resilient structure 58 may comprise nylon or HDPE, for example. In an embodiment, the resilient structure 58 may comprise a spring steel.
The distal end 38 of hook portion 32 may also comprise an attachment feature such as a mounting portion 56.
b illustrates the rod portion 62 in accordance with an embodiment of the present invention.
The body 66 of rod 62 may be roll formed, for example. In an embodiment, the proximal end 64 of the body 66 comprises a channel 68 and a receiving portion 65. As shown, receiving portion 65 may be a section that is substantially flat. Rod 62 is designed to receive movably mounted hook portion 32 within its slot 68 and receiving portion 65, for example. Rod 62 comprises an end 70 for abutment with the abutment portion 54 of the hook portion 32. Rod 62 also comprises an end 71 for abutment with the distal end 38 of the hook portion 32.
The rod 62 may also comprise attachment features such as a rounded edge 72 and a male portion or extended mounting portion or pin 73. Limiting edge 72 and mounting portion 73 may be provided near the proximal end 64 of the rod 62, for example. Limiting edge 72 is designed to cooperate with the extension portion 50, bearing surface 51, and limiting portion 52 of the hook portion 32. The limiting edge 72 also provides an area for the bearing surface 51 to slide thereon along the rod 62, as shown in
The extended mounting portion or pin 73 may be formed with receiving portion 65 or in elongated body 66, for example. The extended mounting portion or pin 73 within the body 66 may be designed to cooperate with the female mounting portion or opening 56 of the hook portion 32. For example, when hook portion(s) 32 are connected to the first and second ends of a rod(s) 62, the opening 56 of the hook portion(s) 32 mate with the male, extended mounting portions 73 of the rod 62 to secure the hook portions 32 to the rod 62. In an embodiment, the extended mounting portion or pin 73 may comprise any number of shapes or designs designed to correspond with the shape of the mounting portion 56 of the hook 32.

In an embodiment, the rod 62 may be formed from 0.4 millimeter (mm) steel material. In an embodiment, the rod may be formed from metal. For example, the rod may be formed from steel, brass, aluminum, or titanium. In an embodiment, the rod may be formed using a roll forming, stamping, extruding and/or punching, or other known manufacturing processes. In an embodiment, hook portion 32 may be formed from a resilient material. In an embodiment, the rod and/or hook portion may be formed from plastic. In an embodiment, the parts of the assembly 30 may be formed via extrusion process.
The assembly process may be performed on a conveyor system, for example. The rod portion 62 and its features (e.g., channel 68, limiting portion 72) may be formed through processes such as roll forming, stamping, extruding and/or punching. The hook portions 32 may be formed by stamping, punching, injection molding, or extrusion processes, for example.
In an embodiment, the assembly process is designed based on speed. For example, due to high volumes, assembly of the features may meet or exceed rates of 200 parts per minute. In order to meet such a criteria, the hook portions 32 are sorted and positioned individually in a hopper or fixture 92. The fixture 92 is designed to hold a plurality of hook portions 32 until the rod is in place for assembly.
The manufacturing and assembly of the hook and rod assembly 30 may comprise the following steps: the rod is formed in the form of a substantially flat piece of material, as shown in
The rod 62 may then be deflected, stamped, or otherwise formed 98 around the hook portion 32 so as to form attachment features for maintaining the hook portion 32 and rod 62 in a mating relationship. For example, in an embodiment, to facilitate assembly, the attachment features (i.e., limiting edge 72, mounting portion 73) of rod portion 62 may be formed from flat portions 96, 94, respectively, during the assembly as shown by
The above described manufacturing and assembly method enables one to fasten or secure the hook portion 32 in the assembly 30 in one motion, thus aiding in the assembly time needed to run this process at a high rate. However, the above noted materials and processes are merely exemplary and should not be limiting, and the rod and hook portions may be assembled using any number of materials and/or processes.
Although the hook and rod assembly 30 is herein described with hook portion 32 removably mounted to rod portion 62, as noted above, in an embodiment, hook and rod assembly 30 may be formed as a single unit. For example, hook and rod assembly 30 may be formed from materials (e.g., such as steel and/or spring steel) that allow for a single or uniform body. In an embodiment, the hook portion 32 may be attached to the rod 62 using known processes for unifying the assembly 30. For example, the hook portion 32 may be formed of spring steel which is attached to a rod 62 of steel.
Also, in an embodiment, the hook and rod assembly 30 may be used alone for mounting to a pair of spaced apart rails. That is, hook and rod assembly 30 need not be used in pairs, as shown with a file folder 10. For example, when hanging a magazine, newspaper, or other object, only one rail may be needed. Thus, the hook and rod assembly 30 may comprise a single rod with a pair of hooks portions, as described above, for hanging on spaced apart rails.
The hook and rod assembly 30 as herein described improves the quality of a file folder. The assembly 30 provides greater strength for holding documents and file therein on rails in a filing cabinet. For example, the roll-forming of the rod portion 62 increases the amount of weight that maybe held by the file folder 10. The rod portion 62 also resists bending and twisting and thus resists deforming and buckling of the rod 62 under a load. The extension portion 80 also increases the strength of the overall assembly.
Also, the assembly 30 provides better engagement with rails 8 by providing minimal contact with the rail 8. By ensuring that only couple of points of the hook come in contact with the rail (e.g., by using a curved portion 48 with a changing radius), the file folder 10 or hook and rod assembly 30 may easily move with respect to the rail, such as when twisted with respect to the rails.
The assembly is also designed to resist derailing or binding of the file folder. The file folder 10 or assembly 30 may be twisted to a maximum gripping angle while in contact with the rail. Additionally, the assembly 30 also increases the ease of sliding the hook and rod assembly 30 of the file folder along the length of a rail. When the file folders or the assembly 30 are moved or adjusted along the rails, such as shown by file folder 6 of
The assembly 30 also allows for one to hang a file folder 10, magazine, or other object along spaced apart rails within cabinets which may not be provided at the same distance, such as along rails within a filing cabinet that may not be parallel or that may not be spaced the same distance from one another in one drawer or cabinet.
While the principles of the invention have been made clear in the illustrative embodiments set forth above, it will be apparent to those skilled in the art that various modifications may be made to the structure, arrangement, proportion, elements, materials, and components used in the practice of the invention.
It will thus be seen that the objects of this invention have been fully and effectively accomplished. It will be realized, however, that the foregoing preferred specific embodiments have been shown and described for the purpose of illustrating the functional and structural principles of this invention and are subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
