Description




BACKGROUND OF THE INVENTION




Modern offices commonly include a plurality of partitions dividing the office space into individual workspaces. Open office plans have been developed to reduce overall officing costs, and generally incorporate large, open floor spaces in buildings that are equipped with modular furniture systems which are readily reconfigurable to accommodate the ever-changing needs of a specific user, as well as the divergent requirements of different tenants. One arrangement commonly used for furnishing open plans includes movable partition panels that are detachably interconnected to partition off the open spaces into individual workstations and/or offices. Such partition panels are configured to receive hang-on furniture units, such as worksurfaces, overhead cabinets, shelves, etc., and are generally known in the office furniture industry as “systems furniture”. Another arrangement for dividing and/or partitioning open plans includes modular furniture arrangements, in which a plurality of differently shaped, freestanding furniture units are positioned in a side-by-side relationship, with upstanding privacy screens attached to at least some of the furniture units to create individual, distinct workstations and/or offices. Both of these types of modular furniture systems, as well as others, have been widely received due to their ability to be readily reconfigured and/or moved to a new site, since they are not part of the permanent leasehold improvement.




Hang-on binder bins have been widely used in office furniture arrangements to provide storage space for books, office supplies and the like. Such binder bins are commonly positioned above worksurfaces to provide for efficient use of the office space, and permit ready access by the user. However, existing binder bins may include relatively complex door opening mechanisms including slides, bearings, pivots, or the like that add to the manufacturing costs and complexity of the unit. Also the mechanism may bind, or otherwise fail, requiring repair to permit proper operation of the binder bin.




SUMMARY OF THE INVENTION




One aspect of the present invention is a storage unit for use in an office environment. The storage unit includes a structural frame having two opposing side panels, at least one laterally extending panel extending between and interconnecting the side panels to define an interior space. The frame includes a perimeter defining an access opening that provides access to the interior space. The storage unit includes a flexible cover having opposing side edges, a front edge, and a rear edge. The flexible cover is attached to the structural frame proximate said rear edge of said flexible cover, and extends freely from the attachment to the frame. The flexible cover has an engagement feature which is selectively engageable with the frame at first and second locations on the frame. Engagement of the cover with the frame at the first location places the flexible cover in a closed position with the opposing side edges of the flexible cover extending proximate the perimeter defining the access opening. Engagement of the flexible cover with the frame at the second location places the flexible cover in an open position wherein the flexible cover is positioned to allow access to the interior space of the storage unit through the access opening.




Another aspect of the present invention is a partition panel system for use in an office environment. The partition panel system includes a partition panel and a storage unit attached to the partition panel. The storage unit has two side panels and a laterally extending panel extending between and interconnecting the side panels. The storage unit defines an interior space and an access opening. The storage unit also includes a flexible cover having opposing side edges, a front edge, and a rear edge. The flexible cover is attached to the storage unit proximate the rear edge of the cover, and extends freely from the attachment to the storage unit. The flexible cover has an engagement feature which is selectively engageable with the storage unit at first and second locations on the storage unit. Engagement of the flexible cover with the storage unit at the first location places the flexible cover in a closed position wherein the cover substantially obstructs access to the interior space of the storage unit. Engagement of the flexible cover with the storage unit at the second location places the flexible cover in an open position wherein the cover is positioned to allow access to the interior space of the storage unit through the access opening.

in a generally overhead position relative to a seated user. Partition


20


is described in detail in commonly assigned, co-pending U.S. patent application Ser. No. 09/881,833, filed on even dated herewith, entitled PANEL SYSTEM, the entire contents of which are incorporated herein by reference. Partition


20


includes a plurality of upright frame members


22


, and upper and lower horizontal frame members


23


and


24


. Each of the upright frame members


22


includes a vertical row of slots

20


.




With further reference to

FIGS. 3 and 4

, the side panels


3


, shelf


4


, and rear panel


18


are all made of a wood material, and are interconnected in a conventional manner. Flexible cover


8


includes thin polymer sheet


31


made of a flexible polymer material that may be opaque, transparent, or colored to provide a pleasing appearance that is compatible with the partition system. Although other materials or thicknesses could be utilized, polymer sheet

. As illustrated in

FIG. 4

, side panels


3


include an edge portion


32


that is offset inwardly relative to the outer portion


33


of side panels


3


, such that the edges


9


of the flexible cover


8


fit closely around the edge


32


when the cover is in a closed position. When the flexible cover


8


is in a closed position, the edges


9


of the polymer sheet


31


are thus positioned below the outer edge portion


34


of side panels


3


. A metal strip


35


extends along the rear edge


11

to receive the edge of the polymer sheet


31


. The metal strip


35


is secured to the rear panel


18


via screws


38


(

FIG. 3

) or the like. Although the rear edge


11


of the flexible cover


8


is thus rigidly connected to the frame


2


of the storage unit


1


, the polymer sheet


31


has sufficient flexibility to permit the flexible cover


8


to be moved to the open position illustrated in FIG.


2


. Slots


15


extend inwardly from the edge


32


, and receive the end portions


12


of the metal strip


17


to retain flexible cover

41


. The relatively large radius


40


permits the polymer sheet


31


to flex around the edge portion


32


to permit the flexible cover


8


to close with side edges


9


contacting edge


32


. Side panels


3


, shelf

26


may be secured to the lower surface


45


of shelf


4


of storage unit


1


in the configuration illustrated in

FIGS. 1 and 2

. Alternately, bracket


26


may be secured to an upper surface


19


of a shelf


43


(FIG.


1


), with the bracket


26


extending upwardly above the shelf


43


. When the bracket


26


is attached to the lower surface


45


of shelf


4


of storage unit


1


, storage unit


1


may be positioned directly adjacent the upper edge


46


of partition


20


, such that a substantial portion of rear panel


18


of storage unit


1


extends above the upper edge


46


of partition


20


. Positioning of the storage unit


1


in this manner permits use of a somewhat lower partition


20


, with storage unit


1


maintaining privacy for the user. Thus, a less expensive, lower partition


20


can be utilized. When bracket


26


is secured to an upper surface


19


of a shelf


43


, the area below the shelf is not obstructed, such that file storage units, cabinets, or other items can be positioned directly below the shelf.




The bracket


26


illustrated in

FIG. 7

is a “right hand” bracket when utilized to support a storage unit


1


in the configuration illustrated in FIG.


1


. Alternately, the bracket


26


of

FIG. 7

can be rotated 180° and utilized as a “left hand” bracket


26


B with shelf


43


as illustrated in FIG.


1


. Bracket


26


includes first and second tabs


47


and


48


, each of which have openings


49


therethrough that accept conventional wood screws or other suitable fasteners for attaching the bracket


26


to a storage unit


1


or to a shelf


43


. A “left hand” bracket


26


may also be made from the same blank of sheet metal by bending the tabs into the positions shown in dashed lines designated


47


A and


47


B in

FIG. 7. A

“left hand” bracket


26


may be utilized in a left hand position when supporting a storage unit


1


, or rotated 180° and used in the right hand position designated


26


A in

FIG. 1

when utilized to support shelf


43


. Thus, a “right hand” bracket


26


can be used in a lower right position to support a binder bin


1


, or an upper left position when supporting a shelf, and a “left hand” bracket


26


can be used in a lower left hand position to support a storage unit


1


, or rotated 180° and utilized as an upper right hand bracket when supporting a shelf.




The storage unit


1


of the present invention has a relatively simple and durable construction that eliminates the complicated and costly slide and/or pivot mechanisms conventionally used for binder bins and the like. The appearance of the storage unit


1


can be readily varied to meet the requirement of a user by selecting a polymer sheet


31


having the desired color and/or light-transmitting properties. The mounting brackets


27


may be configured to readily mount the storage unit


1


on a wide variety of partitions having vertical rows of openings in the partition frame.




In the foregoing description, it will be readily appreciated by those skilled in the art that modifications may be made to the invention without departing from the concepts disclosed herein.
