Additional hanging bracket members incorporated with cross rail frame members support the cross rail frame members on frame members attached to a file drawer.
Description




BACKGROUND OF THE INVENTION




In a principal aspect, the present invention relates to a system for support of hanging files in a file drawer, and, more particularly to an adjustable hanging file system that may be adjusted to support or accommodate files of various dimensions.




Storage of documents, correspondence and the like in file drawers by means of hanging files is a well-known expedient. There are numerous examples in prior art patents which disclose systems that are installed in file drawers for the purpose of supporting hanging files. For example, U.S. Pat. No. 5,393,136 granted Feb. 28, 1995 for a Drawer With a Convertible Filing Support System discloses a mechanism wherein a file support system may be installed in a file drawer to accommodate various sizes of hanging files. Other patents including the following depict various hanging file systems which may be incorporated into file drawers: U.S. Pat. No. 4,726,635 issued Feb. 23, 1988 for Hanging File Folder Support Assembly for Drawers; U.S. Pat. No. 5,494,175 issued Feb. 27, 1996 for Hanging File Support Structure for a Drawer; U.S. Pat. No. 5,873,642 issued Feb. 23, 1999 for Hanging File Bar Support Assembly for a Drawer; U.S. Pat. No. 5,678,797 issued Oct. 21, 1997 for a Flush Mounted Support Bracket; U.S. Pat. No. 4,887,873 issued Dec. 19, 1989 for a File System with Hang Rail; U.S. Pat. No. 4,869,563 issued Sep. 26, 1989 for a Single Piece Construction File Hanger; U.S. Pat. No. 4,219,247 issued Aug. 26, 1980 for Suspended Filing Drawer; and U.S. Pat. No. 3,456,994 issued Jul. 22, 1969 for a File Folder Suspension For Drawers.




While all of these prior art systems appear to be useful, a need has remained for an improved system which permits ease of adjustment of the hanging file system within a drawer to accommodate hanging files of various sizes with a minimum amount of effort. Concomitantly, a file drawer hanging support system which is rigid and rugged yet is inexpensive, easy to install and requires a minimum amount of tooling in order to install, repair and replace is a desired goal.




SUMMARY OF THE INVENTION




Briefly, the present invention comprises a hanging file system that includes frame members and custom bracket members that are cooperative with the frame members to form a grid in a file drawer which is adjustable to accommodate hanging files of various dimensions. Each frame member is preferably formed with a u-shaped cross section and thus includes a first depending skirt and a spaced, parallel, second depending skirt, the first and second depending skirts being connected by a top crown section thereby resulting in a longitudinal slot in the bottom side between the skirts. The open bottom side or slot of each frame member is adapted to receive support brackets affixed to the sides of a drawer. A grid of frame members may thus be attached to the walls of a drawer. By providing frame members which are comprised of generally parallel, elongate, spaced side skirts connected by a crown to define a bottom slot or channel, one may insert the supporting bracket members into the channel in a manner which avoids interference with hanging files suspended or supported on the top crown of the frame members. The structure of the frame members also enables positioning and secure attachment of the bracket members to the frame members. That is, each bracket member includes a portion or element which fits between parallel skirts of a frame member thereby facilitating attachment of the frame member to the bracket member.




Additional molded brackets or bracket members support cross frame members on the basic grid of frame members attached to a drawer. Further, the spacing of the additional cross frame members is easily adjusted to accommodate various sizes of hanging files.




The construction enables the utilization of light gauge metal which, because of the ability to shape the metal with appropriate reinforcing ribs and ridges including a connecting crown section, enables support of heavy loads by a lighter gauge material.




Thus, it is an object of the invention to provide an improved adjustable hanging file system.




It is a further object of the invention to provide an adjustable hanging file system which is capable of supporting significant loads.




Another object of the invention is to provide a hanging file system which may be manufactured from lighter gauge metal relative to prior art systems, yet which provides significant rigidity and support equivalent to such systems while being lighter in weight and more easily manufactured.




Another object of the invention is to provide a hanging file system which can be easily adjusted to accommodate all sizes of files without utilization of special tools.




Another object of the invention is to provide a hanging file system that can be easily installed in existing file cabinets with a minimal amount of tools and without special installation equipment.




A further object of the invention is to provide a hanging file system that includes bracket members that support frame members on the side walls of a drawer by engaging and fitting against the edge of the drawer walls.




Yet another object of the invention is to provide bracket members cooperative with u-cross section shaped frame members that adjustably engage and support the frame members on a grid of similar frame members attached to the walls of a drawer.




These and other objects, advantages and features of the invention will be set forth in the detailed description which follows.

DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to the figures, and in particular,

FIG. 1

, the adjustable hanging file system of the invention is comprised of four basic elements. The first element is a frame member


30


. Each frame member


30


comprises an elongate, formed metal rail described in greater detail below. The frame members


30


are supported on the inside of a file drawer cabinet


32


by a second element, molded brackets or bracket members


34


. Multiple bracket members


34


support each frame member


30


although the bracket members


34


may be varied in design in accord with the design of the file drawer and the hanging support system installed in the drawer.




The third element is a cross rail bracket or bracket member


36


which is fitted into the ends of frame members


30


thereby enabling such frame members


30


to be supported as cross frame members by the grid of frame members


30


attached to a drawer


32


. The fourth element comprises cap members


38


fitted into opposite ends of certain frame members


30


.




In sum, there are four basic components in the system: frame members


30


, frame member mounting brackets


34


, frame support or cross rail brackets or bracket members


36


, and frame end caps


38


. In the following figures, each of these separate components is depicted and a description is provided.

FIGS. 2-4

construction.




Referring to

FIGS. 2-4

, rail or frame member


30


is comprised of a first elongate skirt


40


and a second elongate skirt


42


. The skirts


40


and


42


are spaced from one another, are generally parallel and are connected by a crown section or crown


44


. Each skirt, for example, skirt


40


includes a series of formed, parallel elongate reinforcing side ribs


46


and


48


. The side ribs


46


and


48


provide additional structural integrity for the frame member


30


. Various patterns of side ribs


46


may be employed, e.g., continuous, discontinuous, angled, etc.




In the preferred embodiment, the crown


44


has an arcuate shape in cross section, although various other shapes in cross section may be adopted for the connecting crown


44


. In the preferred embodiment, the lower edge


41


,


43


of each skirt


40


and


42


is folded or formed upwardly and inwardly as depicted in

FIG. 4

to avoid any sharp edges from being engaged by a user of the system and to enhance structural integrity. Opposed, aligned openings


50


and


52


in skirts


40


and


42


are provided along the length of the skirts


40


and


42


. The openings


50


and


52


define detents through which fasteners, e.g., rivets


39


, may be inserted to hold the various component parts together or otherwise cooperatively engage and position the brackets


34


,


36


and end cap


38


in a detent position. The brackets


34


, as well as end caps


38


are typically held in position by fasteners


39


extending through the openings


50


,


52


. The cross rail brackets


36


typically include detent projections


68


which engage in the openings


50


or


52


to hold the cross rail brackets


36


and thus the cross rail frame members


30


associated therewith in position.





FIGS. 5-9

illustrate the cross rail support brackets


36


. The cross rail support brackets


36


typically include a hook section


60


with a downwardly depending plate


62


extending from hook section


60


. The hook


60


includes an inner curved section


66


which is designed to fit over and engage smoothly with the top or outside of crown


44


of a frame member


30


. Inside surface of plate


62


includes a projecting prong or tab


68


which is designed to engage with an opening such as opening


50


or


52


in the side of frame member


30


.




Extending transversely from the plate


62


is a mounting flange


64


. Preferably the mounting flange or transverse plate


64


extends at a right angle from the downwardly extending plate


62


. As shown in

FIG. 5

, the transverse plate


64


also includes a transverse passage


70


. The passage


70


may be aligned with openings


50


and


52


for insertion of a fastener, e.g., fastener or rivet


39


, therethrough to attach a frame member


30


onto the plate


64


. Preferably, bracket


36


includes a lip or flange


45


which is positioned over and spaced from the top edge of plate


62


. This lip


45


covers or fits over the crown


44


and end of frame member


30


into which bracket


36


is inserted and thereby functions to prevent files from sticking into or engaging any gap at the attachment end of frame member


30


.





FIGS. 10-23

illustrate various embodiments of support brackets


34


that are used in combination with frame members


30


to support or attach frame members


30


onto the sides of a drawer panel


32


. Typically, each bracket


34


includes an upwardly projecting tab or section


80


which has a width substantially equal to the width of the space between the skirts


40


and


42


. The upwardly projecting section


80


thus has parallel side walls that fits between the inside of skirts


40


and


42


. An opening or passageway


82


through the section


80


is provided for receipt of a fastener


39


which attaches the bracket


36


to the frame member


30


. Note skirts


40


,


42


may be parallel or may diverge slightly outwardly from crown


44


.




A downwardly projecting attachment tab on section


84


is provided with an opening


86


for receipt of a fastener


87


to enable attachment of the bracket


36


to a panel


32


such as illustrated in part in

FIG. 11. A

flange surface


89


projects laterally from the junction between the upper section


80


and the lower section


84


to facilitate alignment of the bracket


36


on the side edge of panel


32


and to support the weight of the frame and files supported by the frame. This flange


89


feature reduces the load on the fasteners


87


as well as facilitating alignment of the bracket and frame members


30


.





FIGS. 16-23

illustrate various alternatives for the construction of the support bracket


34


wherein the relationship of the position of the upwardly depending upper section


80


is adjusted relative to the lower bracket attachment section


84


. In each instance, however, there are provided separate sections with openings through the center thereof for attachment to a panel


32


and the frame member


30


respectively. Further, a flange


89


is provided in most instances to enable positioning of the bracket


36


appropriately with respect to the edge of a drawer side wall or panel


32


. Thus, the orientation and relationship of the frame members


30


relative to the side panels


32


of a drawer may be adjusted to accommodate the design of the drawer. Other types of bracket members


34


may also be provided, for example to recess the frame members


30


within the drawer


32


in alignment with the upper edge of the panels


32


of the drawer. Thus, the particular design of the bracket


34


may be widely varied depending upon the installation to be effected.





FIGS. 24-26

illustrate a typical end cap


38


which fits into or slides into the end of a frame member


30


. The end cap


38


includes an outer peripheral flange


90


which limits the extent of insertion of plate on main body


92


of the end cap


38


between the rails


40


,


42


of frame member


30


. A transverse opening


94


is provided in end cap


38


through which a fastener


3995


may be fitted to retain the end cap


38


in position. The end caps


38


provide an additional protective function to the ends of the frame member


30


and also, because the width of the insert


92


is substantially equal to the distance or width or space between the skirts


40


and


42


, the end cap


38


provides additional structural integrity for the frame member or rail


30


.




Similarly, the upwardly extending sections


80


of the brackets


34


enhance the structural integrity of the frame members


30


. The frame members


30


are made from a lighter gauge steel than many prior art support systems, yet provide wide surfaces, namely, the crown


44


and side skirts


40


,


42


upon which hanging files may be rested. The frame members


30


thus are lightweight yet have enhanced structural integrity due to the parallel design and position of the skirts


40


,


42


as well as the reinforcing ribs


46


and


48


and the crown


44


all of which promote the structural integrity of the system.




In use, the rails or frame members


30


are cut to a proper length and installed on the opposite sides of the vertical side wall panels


32


forming a drawer and optionally at the rearward and forward ends thereof by means of attachment brackets


34


. Additional frame members


30


of appropriate length are then provided with cross member brackets


36


at their opposite ends. Note that the cross member brackets


36


are formed so that the transverse plate


64


is positioned to maintain the surface of crowns


44


in a coplanar relationship with the crowns


44


of frame members


30


that are positioned at right angles with respect thereto. That is, the crowns


44


of all the frame members


30


, are all coplanar.




The cross frame members


30


having cross rail brackets


36


thereon are fitted over the frame members


30


mounted on the sides of the drawer


32


. The cross frame members (


30


A in

FIG. 1

) spacing may be adjusted and the detent projection


68


may engage an opening


50


,


52


to maintain the cross frame member (


30


A in

FIG. 1

) in a desired spaced position. The cross frame members


30


are easily moved between detent positions to thereby adjust for support of differently sized files. Also the cross frame members


30


may be constructed to extend for the length or width of the drawer and may also form intermediate support frame members (


30


B in FIG.


1


). Thus the arrangement and adjustment of frame members


30


is highly variable and may accommodate a broad range of file sizes and arrays. The crowns


44


of the frame members


30


in the various arrays are coplanar in view of the design of the various cross rail or cross member brackets


34


,


36


. The end caps


38


are optional elements.




It is possible to vary the construction without departing from the spirit and scope of the invention. For example, as previously noted, the construction of the brackets


34


and


36


may be varied. The cross sectional configuration of the frame members


30


may be varied, eg the shape of the crown


44


and the shape of the side skirts


40


,


42


. The end cap


38


construction may also be varied and, in fact, end caps


38


may be provided which act to connect and join adjacent frame members


30


arranged at angles to one another or in a linear array. Thus, the end caps


38


may serve as linear connectors of lengths of frame members


30


. Therefore, the invention is to be limited only by the following claims and equivalents thereof.
