Description
- This application claims the benefit under Title 35, U.S.C. §119(e) of U.S. Provisional Application Serial No. 60/291,700, entitled V-FOLD DRAWER WITH FILING EXTRUSION, filed May 17, 2001.
- 1. Field of the Invention
- The present invention relates to office furniture systems, and in particular, to a drawer or other container for office furniture systems which is configured to hold hanging file folders therein.
- 2. Description of the Related Art
- Office furniture systems, including desks and workstations, for example, typically include drawers or other containers associated therewith which are configured to hold hanging file folders therein. Hanging file folders generally include a hinged file folder having a plurality of hanger clips attached to the free edges thereof opposite the hinge for hanging the file folders from the hanging structure of a drawer. The hanging structure of the drawer typically includes one or more rails, bars, or other elements which are fastened or clipped onto the upper portions of the drawer walls.
- One method of manufacturing such a drawer includes cutting a groove in one of the side faces of an elongate drawer plank adjacent a lower portion thereof. Then, a plurality of V-shaped miter cuts are made intermediate the ends of the drawer plank to define a plurality of drawer walls therein, which cuts are perpendicular to the long dimension of the drawer plank. Next, a base panel is provided which is fitted within the grooves in the walls of the drawer plank, followed by folding the drawer plank about the miter cuts, and attaching the ends of the drawer plank to one another to thereby form a drawer having a base panel with a plurality of vertical walls therearound. After forming the drawer, the file hanging structure is attached to the upper portions of the drawer walls.
- A problem with such drawers is that, after the drawer is formed as described above, the subsequent attachment of the file hanging structure to the drawer is a time-consuming task, typically requiring a number of individual assembly steps which must be performed by hand. For example, one file hanging structure includes four rail members, which each must be attached to the upper portions of the drawer walls using a plurality of screw fasteners. Other file hanging structures include, for example, a plurality of corner blocks with rail members extending therebetween, or a plurality of individual extruded rail members which are separately attached to each of the drawer walls by fitting protruding tongues thereof within corresponding grooves cut in the top edges of each of the drawer walls.
- What is needed is a drawer for hanging file folders, which drawer may be made according to a process wherein the step of separately attaching the several components of the file hanging structure to the drawer after the drawer is formed is eliminated, such that the drawer is easier and less costly to manufacture.
- The present invention provides a drawer for hanging file folders, which is formed from a drawer subassembly including an elongate drawer plank to which is attached, along a longitudinal edge thereof, an elongate plastic or metal support rail or extrusion piece from which hanging file folders may be hung. The drawer subassembly is subsequently folded about a plurality of hinge portions therein which are common to the drawer plank and to the support rail, and a base panel is captured within the drawer subassembly as same is folded to define a drawer including a base panel surrounded by a plurality of vertical walls from which hanging file folders may be hung.
- The support rail includes an upper portion having a U-shaped, L-shaped, or any other cross section which may support hanging file folders, and a lower portion thereof may include a longitudinal connecting tongue which is adapted to fit within a corresponding longitudinal groove disposed within the top edge of the drawer plank. The drawer plank additionally includes a groove cut in one of the sides faces thereof adjacent a lower portion of same into which the base panel is captured, and also includes one or more connecting elements associated with the first and second longitudinal ends of the drawer plank.
- To form the drawer, the connecting tongue of the support rail is fitted within the groove along the top edge of the drawer plank, or the support rail is otherwise attached to the drawer plank, in order to form the drawer subassembly. Subsequently, a series of V-shaped miter cuts are made in the drawer subassembly through part of the thicknesses of the each of the drawer plank and the support rail to define the hinge portions of the drawer subassembly. The miter cuts are disposed perpendicular to the long dimension of the drawer subassembly, and, along with the ends of the drawer subassembly, define a plurality of drawer walls therein. Thereafter, the drawer subassembly is folded about the hinge portions with a drawer base panel captured within the grooves in the lower portions of the drawer walls, and the first and second ends of the drawer plank are subsequently attached to one another to form the drawer.
- Advantageously, the attachment of the support rail to the drawer plank prior to making the miter cuts in the drawer subassembly and folding same to form the drawer obviates the need to separately attach multiple components of a file hanging structure to the drawer walls after the drawer is formed, thereby decreasing the difficulty and cost of manufacturing the drawer.
- Additionally, the U-shaped cross section of the upper portion of the support rail allows a plurality of adjacent drawer subassemblies to be pushed together through an automated assembly line in which each of the miter cuts are made in a plurality of drawer subassemblies simultaneously, because the U-shaped cross sections of the support rails contact the edges of adjacent drawer subassemblies in a manner which prevents adjacent drawer subassemblies from overlapping one another when multiple drawer subassemblies are pushed through the assembly line.
- In one form thereof, the present invention provides a drawer for containing hanging file folders, including an elongate drawer plank; an elongate support rail attached to the drawer plank and adapted to support at least one hanging file folder therefrom, the drawer plank and the support rail having a plurality of common hinge portions therein about which the drawer plank and the support rail are folded to define a drawer having a plurality of vertical walls.
- In another form thereof, the present invention provides a method of manufacturing a drawer for hanging file folders, including the steps of providing a drawer subassembly including an elongate drawer plank to which is attached an elongate support rail adapted to support at least one hanging file folder, the drawer subassembly having a long dimension defined between first and second ends; forming a series of hinge portions in the drawer subassembly intermediate the first and second ends, the hinge portions disposed perpendicular to the long dimension of the drawer subassembly; and folding the drawer subassembly about the hinge portions to define a drawer having a plurality of walls.
- The above-mentioned and other features and advantages of this invention, and the manner of attaining them, will become more apparent and the invention itself will be better understood by reference to the following description of embodiments of the invention taken in conjunction with the accompanying drawings, wherein:

- Corresponding reference characters indicate corresponding parts throughout the several views. The exemplifications set out herein illustrate preferred embodiments of the invention, and such exemplifications are not to be construed as limiting the scope of the invention in any manner.
- Referring to FIG. 1,
drawer subassembly 20 is shown, which is a component of hangingfile folder drawer 22, shown in FIG. 6.Drawer 22 may hold therewithin a plurality of hangingfile folders 24, as described further below.Drawer subassembly 20 generally includesdrawer plank 26 andsupport rail 28. -
Drawer plank 26 may be formed of solid wood, pressed particle board, medium density fiber board, or an extruded plastic material, for example.Drawer plank 26 is elongate in overall shape, and includes opposite first andsecond ends lower edges outer side faces first groove 42 is cut longitudinally alongupper edge 34 ofdrawer plank 26, and asecond groove 44 is cut longitudinally ininner side face 38 ofdrawer plank 26 adjacentlower edge 36 thereof. Connecting elements are associated with each of first andsecond ends drawer plank 26, which connecting elements are shown in FIG. 1 as a plurality ofdowel rods 46 infirst end 30, which may be fitted within a plurality of corresponding holes 48 (FIG. 4), adjacentsecond end 32 to secure first andsecond ends - Referring to FIGS. 1 and 1A,
support rail 28 is also elongate in overall shape, and includes upper portion 50 and lower portion 52. Upper portion 50 includesbase 54 and a pair ofparallel rail members 56 extending therefrom such that, as shown in FIG. 1A, upper portion 50 defines a U-shaped cross section. Alternatively,base 54 may only include onerail member 56 extending therefrom such that upper portion 50 defines an L-shaped cross section, as shown in FIG. 7. Lower portion 52 ofsupport rail 28 includes longitudinal connectingtongue 58 having a plurality of barbs 60 extending from opposite sides thereof.Support rail 28 may be an extrusion piece formed of metal, or a single piece of extruded plastic material, such as polyvinyl chloride (PVC), for example. - To attach
support rail 28 todrawer plank 26,tongue 58 ofsupport rail 28 is fitted or pressed withingroove 42 ofdrawer plank 26 as shown in FIG. 1, such that barbs 60 oftongue 58 are embedded withindrawer plank 26 to firmly and securely attachsupport rail 28 todrawer plank 26, formingdrawer subassembly 20, as shown in FIG. 2. - Thereafter, a series of hinge portions62 a-c are formed in
drawer subassembly 20. As shown in FIG. 3, such hinge portions are defined by a plurality of V-shapedmiter cuts 63 a-c made through a portion of the thicknesses of each ofdrawer plank 26 andsupport rail 28 ofdrawer subassembly 20, whereinmiter cuts 63 a-c are cut in a direction perpendicular to the long dimension ofdrawer subassembly 20. As shown in FIG. 3, threesuch miter cuts 63 a-c may be made indrawer subassembly 20 to define three hinge portions 62 a-c, and also to define fourdrawer walls 64 a-d, withfirst drawer wall 64 a defined betweenfirst end 30 ofdrawer subassembly 20 andfirst hinge portion 62 a,second drawer wall 64 b defined between first andsecond hinge portions 62 a,b, third drawer wall 64 c defined between second andthird hinge portions 62 b,c, andfourth drawer wall 64 d defined betweenthird hinge portion 62 c andsecond end 32 ofdrawer subassembly 20. - Referring to FIGS. 7 and 8,
miter cuts 63 a-c indrawer assembly 20 may be made simultaneously by a cutting tool including a plurality of cutting members, one of which is shown in the form ofblade 66. The cutting tool comprises part of anautomated assembly line 68 which also includes pushingmember 70. Pushingmember 70 pushes a group including a plurality ofdrawer subassemblies 20 throughassembly line 68 in a manner in whichdrawer subassemblies 20 abut against one another such that the support rails 28 of onedrawer subassembly 20 abut againstlower edge 36 ofdrawer plank 26 of anadjacent drawer subassembly 20. - As illustrated in FIG. 7, if support rails28 of
drawer subassemblies 20 have an L-shaped cross section, as described above, it has been found that overlap between the support rail of one drawer subassembly and the bottom edge of an adjacent drawer subassembly may occur when a group ofadjacent drawer subassemblies 20 are pushed through automatedassembly line 68. If the foregoing overlap occurs,blades 66, rather than making miter cut 63 a-c through only portion of the thickness ofdrawer subassemblies 20, may cut entirely through one ormore drawer subassemblies 20. Therefore, support rails 28 which have such an L-shaped cross section may not be preferred in an automated manufacturing process in which a plurality ofdrawer subassemblies 20 are pushed in a flat manner adjacent to one another through anautomated assembly line 68, as described above. - Alternatively, referring to FIG. 8, if the support rails28 of the
drawer subassemblies 20 have a U-shaped cross section, as described above, the pair ofrail members 56 of upper portion 50 thereof (FIG. 1A) press against an adjacentlower edge 36 of anadjacent drawer subassembly 20 at two points of contact onlower edge 36, such that overlap ofadjacent drawer subassemblies 20 is prevented. In this manner, a plurality ofdrawer subassemblies 20 may be pushed through automatedassembly line 68 adjacent to one another without overlapping ofadjacent drawer subassemblies 20, such thatblades 66 cut through only a portion of the thicknesses ofdrawer subassemblies 20 to makemiter cuts 63 a-c therein. - Referring to FIG. 4, after
miter cuts 63 a-c are made indrawer subassembly 20,drawer subassembly 20 is folded about hinge portions 62 a-c. Additionally,drawer base panel 71 is inserted withingrooves 44 ofdrawer plank 26. Afterdrawer subassembly 20 is thus folded aboutbase panel 71 and about hinge portions 62 a-c to capturebase panel 71 therein,dowel rods 46 offirst end 30 ofdrawer plank 26 are fitted within the correspondingholes 48 insecond end 32 ofdrawer plank 26, and a suitable adhesive, such as a hot melt glue, for example, is applied therebetween. An adhesive may also be applied if desired betweenbase panel 71 andgrooves 44 indrawer plank 26. Referring to FIG. 5, afterdrawer subassembly 20 has been thus folded to definedrawer 22,drawer 22 is fixedly held in a square orientation by a plurality of holdingelements 72 of a holding machine or jig until the adhesive cures. - After the adhesive cures,
drawer 22 may be removed from the holding machine or jig, and suitable drawer hardware such as drawer slide 74 for example, may be attached thereto for slidably attachingdrawer 22 to a piece of office furniture. Hangingfile folders 24 may be hung withindrawer 22 onsupport rail 28, such thatclips 76 offolders 24 are hung on and supported bysupport rail 28 withfolders 24 disposed withininterior space 78 ofdrawer 22. - As may be appreciated from the foregoing assembly process, the attachment of
support rail 28 todrawer plank 26 to formdrawer subassembly 20 before hinge portions 62 a-c are formed therein, and also beforedrawer subassembly 20 is folded to definedrawer 22, obviates the additional manufacturing steps of separately connecting the several components of a file hanging structure todrawer 22, thereby decreasing the difficulty and cost of assemblingdrawer 22. - However, various details regarding the construction of
drawer 22 may vary from that described above. In particular, the shape ofsupport rail 28 may vary widely from the foregoing L-shaped or U-shaped configurations described above. For example,support rail 28 could have a T-shaped or W-shaped cross section, or any other shape adapted to supportclips 76 of hangingfile folders 24. - For example, as shown in FIG. 10,
support rail 100 includesupper portion 102 havingbase 104 and a pair ofparallel rail members 106 extending therefrom, andlower portion 108 ofsupport rail 100 includesslot 110 for supporting rod orcrossbar 112 from which hanging files 24 may also be hung in an orientation perpendicular to any hanging files which are hung fromrail members 106.Support rail 100 also includes connectingtongue 58, similar to that ofsupport rail 28, for connectingsupport rail 100 todrawer plank 26. Referring to FIG. 14,support rail 136 is shown, which is similar to supportrail 100, whereinsupport rail 136 includes asingle rail member 106. Referring to FIG. 17,support rail 140 is shown, which is also similar to supportrail 100, and includesarms 142 for attachingsupport rail 140 todrawer plank 26. - Referring to FIG. 11,
support rail 114 includescentral portion 116 andparallel rail members 118 defining an H-shaped cross section from which hanging files 24 may be hung, withdrawer plank 26 received betweenrail members 118 for attachingsupport rail 114 todrawer plank 26.Support rail 150, shown in FIG. 16, is similar to supportrail 114, and includes a singleelongated rail member 118 to define an upper portion ofsupport rail 150 having an L-shaped cross section. - Referring to FIG. 12,
support rail 120 includesbase portion 122 withU-shaped section 124 attached thereto from which hanging files 24 may be hung.Support rail 120 also includes connectingtongue 58, similar to that ofsupport rail 28, for connectingsupport rail 120 todrawer plank 26. In FIG. 15,support rail 160 is shown, having an upper portion with a T-shaped cross section, and further including connectingtongue 58. - Also, barbs60 of
tongue 58 ofsupport rail 28 may be eliminated, in favor of the use of fasteners, an interference fit, or an adhesive, for example, to attachsupport rail 28 todrawer plank 26. In view of the foregoing, groove 42 may be eliminated fromupper edge 34 ofdrawer plank 26. For example, as shown in FIG. 11,support rail 114 is attached todrawer plank 26 by the engagement betweenupper edge 34 ofdrawer plank 26 betweenparallel rail members 118 ofsupport rail 114, andparallel rail members 118 may also includeinternal barbs 144, shown in FIG. 18, for engaging side faces 38, 40 ofdrawer plank 26 adjacentupper edge 34 thereof. Also, as shown in FIG. 13,support rail 114 may additionally include a pair ofprotrusions 126 extending interiorly of the lower ends ofparallel rail members 118, which protrusions 126 engagegrooves 128 respectively formed in eachside face drawer plank 26 adjacentupper edge 34 thereof. - Additionally, as shown in FIGS. 9 and 19,
drawer subassembly 130 may only include twohinge portions drawer assembly 130, when folded about such hinge portions, defines only three walls orsides 132 a-c ofdrawer 22, to which afourth side 132 d may be separately attached, if desired. As shown in FIG. 9,fourth side 132 d may comprise a drawer front including suitable drawer pull hardware, such aspull knob 134.Fourth side 132 d may be attached to the front edges ofsides 132 a,c as shown in FIG. 9, or alternatively, as shown in FIG. 19,fourth side 132 d may be attached to the interior faces ofsides 132 a,c adjacent the front edges thereof such thatfourth side 132 d is captured betweensides 132 a,c. - While this invention has been described as having a preferred design, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
